Effects of Social Media on Young Adults Essay

Looking at the average Millennial, one would see him toting all his smart devices and would wonder if Millennials are ever disconnected – from technology or from each other. The Millennial Generation, more than any other generation, feels the need to be constantly linked to each other. For young American adults aged 18-32, technology is their life; virtual reality has come to supersede physical reality. In what seems like every second of every day, teenagers can be found on their computers, tablets, and cell phones, searching though pages of social media. In fact, statistics prove that they are: an average teenager has 201 Facebook friends and 73% of teenagers are on at least one social network (Thomas). Across Facebook, Tumblr, Instagram and Twitter alone it shows how cyber space is endless. According to Social Media Watch, Twitter now boasts that as of May 2, 2013 it has 359 million active users; Facebook still holds the top social media spot with 701 million active users. Thanks to the sizeable growth in online activity, the Millennial Generation has lost touch with interpersonal communication. If not monitored, online social networking will become detrimental to the Millennial generation and following generations’ social and psychological development, as the anonymity of cyber space has been shown to encourage negative behavior, leading to increased feelings of disconnection from others. Each generation spends their childhoods in different ways. As for this century, Millennials find themselves trapped in the world of media, populated by televisions, radio, magazines, mobile phones, laptops and the Internet, which gives young adults access to what most young adults crave, social media.

There seems to be no decline for â€Å"the social networking movement. † Just a few examples of the seemingly infinite types of online networking are: Facebook, Twitter, Instagram, Linkedin and YouTube. According to Amanda Lenhart, of New York Department of Health, 93% of young adults go online. (Lenhart). With such a strong amount of people accessing the Internet, the dangers that can come from the massive amount of time spent online must be discussed. Social networking is being used as a new tool necessary for a growing technological society. Teenagers, being a large part of the online generation, have been caught up in the allure of online social networks and the way they have revolutionized how people go about their daily activities. A study showed that 48% of people ages 18-34 years old check Facebook when they wake up (Statistics Brain). This shows how highly young adults prioritize social media. Due to the excessive amount of time spent on these networks and the online freedom that young people have to continuously explore different social networking sites, they are prone to the negative effects it has on their development. While it may seem that social media is required for social survival in today’s society, in actuality it is just a way of communicating with greater ease. With moderation, social networks are vital to American culture. It is when these websites are abused with the intent to bully others, and once they are considered the only hobby for young adults, that they can become increasingly more dangerous. A large problem arises from communication via technology in lieu of face-to-face conversations, and its prevalence over other activities such as reading, sports, or other hobbies that positively shape the mind and body instead of being a catalyst for negative behavior. Social networking is affecting the schoolwork and test results of America’s youth. Researchers have found that the middle-school, high school and college students who used Facebook at least once during a 15 minute period get lower grades overall (Cosby). While they are trying to do homework students have a tendency to attempt to multitask and do their homework while simultaneously on different social media outlets. They claim to be successfully multitasking, but they are unaware of the affect these distractions are having on them. In reality, their efforts to multitask are making the simple task they were trying to accomplish take significantly longer than it ordinarily would. A study was performed at two West Coast high-tech firms to observe how many times employees were interrupted and the impact it had on their work. Each time a worker was distracted from a task, it would take an average of 16 minutes for the employee to return to the previous menial task they were in the process of doing. Even worse, some people forgot what they had been working on all together, showing effects on short-term memory (Sladick). This shows how impactful constantly checking social media or the interruption of a text message can be when working on something as small as writing an email. One of damaging effects of being â€Å"plugged in† all the time is this generation’s struggle to correspond with each other properly. Amanda Lenhart expresses her fear for the generation following her by speaking to the fact that 51% of young people primarily communicate with each other through texting, 42% use social media as a secondary source, and only 29% talk to each other as part of other activities outside of school (Lenhart). With online social interaction being so abundantly available to young adults, most would rather talk to someone over text messages or the Internet and avoid face-to-face contact, because of the stress that can come from talking to someone in person. America’s youth are showing a severe lack in the social skills necessary to be successful later in life, which will be harmful to the future success of American society. There are 30 million messages sent through Facebook every 20 minutes (Statistics Brain). While it may seem like a generation with a constant link to each other, brought on by the enormous quantity of messages sent between them, would have a excessive feeling of togetherness and an abundant number of fulfilling relationship, ironically, it is speculated these messages do not serve the same quality connection that one gets from an interpersonal conversation. A lack of interpersonal conversation ultimately leaves them feeling unhappy. There have been studies that prove the increased levels of Internet use have been associated with higher levels of depression and loneliness (Kersting). These online conversations do not provide people with the person to person bond that humans require to feel successful, but are more along the lines of shallow exchanges that include messages such as, ‘sup? ’ that would only require the simplest of responses, ‘nothing, u? ’. With this being the primary type of communication that they use, young people are unable to see the flaws that come from this type of interaction and how it will lead them to be dissatisfied if it continues to be the majority of how they communicate. The young adults have not learned the proper way to connect with other people nor have they used different conversational skills, or had to deal with different possibly complicated interpersonal situations, and they do not know how to get to know a person from somewhere other than behind the screen. Social media has a profound effect on American culture. The increase in technology brings forth the same idea of ‘which came first, the chicken or the egg? ’ Are the characteristics of the Millennial Generation: the need for instant gratification, the short attention spans, desire to be constantly connected, and the need to regularly multitask, because of the accessibility of technology? Or is the perpetual improvement of technologies in order to keep up with Millennials? Studies have shown a simultaneous rise of narcissism and social media usage in the Millennial generation, which raises the question: is there a relationship between the two? Narcissists are usually unable or unwilling to form connections that require emotional investments, such as face-to-face friendships, but still desire the social admiration and attention that a large number of friendships can offer (Bergman). This is the epitome of a person with thousands of ‘friends’ on his or her Facebook, who frequently participates in extensive, but insubstantial activity online. He or she feels loved, which increasingly fuels their narcissistic behavior. This is only one of the negative side effects that are on the upswing with the increased use of social technologies, others on the rise include aggression, anxiety and depression. The endless use of technology is affecting every part of people’s lives. With so many outlets for people to communicate with, the American culture has developed an addiction to social networking websites. People have been known to sleep with their phones, making different social media site the last thing they see each night, and allowing them to be contacted at any time of the night. Dr. Roseanne Barker, of The Barker Sleep Institute, says, â€Å"Americans are getting a lot of light exposure through electronics and technology during that last hour before sleep†¦ And it decreases the brain’s natural production of melatonin. † Melatonin is the body’s sleep-promoting hormone, she explains, and when phones constantly ring and beep throughout the night, it causes sleep fragmentation and disruption. Barker sees the issue in patients of all ages, but it is increasingly affecting the youth (Meckles). With adults placing technology at such a high place on their priority list, the idea is trickling down to America’s youth. Adolescents see the amount of time people older than them spend on the different types of social media and assume that the same behavior is acceptable for themselves. Studies claim a direct link between the use of cell phones and social networking and medical issues, like seizures and radiation (Meckles). A large problem coming from the hold technology has over people is how it affects their overall lifestyle, in this case their sleeping patterns, which causes an increase in more serious health effects that will affect them in the long run. One might say that social media has transformed the Internet into a tool that has made communication easier and more accessible. These networking sites allow people to communicate with people across the globe, showing them about how the other side lives. But what happened to it being dangerous for young people to engage in communication with strangers? Sure, a young person might think ‘this person is thousands of miles away, he or she can’t cause me any harm, why not add this person as a friend on Facebook? They could never find me in real life. ’ People have a false sense of security through the Internet. They find comfort in the anonymity available to them on social media sites. They feel a freedom from real life and freedom from consequences. Moreover, social networking offers young adults a place that puts a great emphasis on acting immorally. For example, all the different inappropriate themes posted all over the Internet that prompts impressionable young minds to think things that are usually seen as morally wrong are actually normal. Not to mention the danger that comes with certain social networking applications, such as Tinder. An application that uses a person’s GPS location to find people in his or her area and ‘matches’ them. Allowing the user to decide if he or she like a persons picture, if they do, the two people are allowed to communicate with each other through the application. Not only does that promote the importance of looks and allows a person to potentially create a fake identity to attract whatever type of person they are looking for, but it is a slyly built ‘dating’ site designed for teenagers. A person could mistakably be under the impression that it had a similar inconspicuousness that came with talking to a person across the globe, but actually be unknowingly be putting himself or herself at risk with a potentially dangerous person in his or her area. Anonymity causes people to question the validity of anything that is written on the Internet. If anyone is able to write whatever he or she feels on the Internet, then that is more difficult to determine what is true and what is false. This causes people to question everything they read even when the legitimacy is stated and has been proven. A recent study by researchers at the University of Wisconsin-Madison found that the negative comments on science articles affected how people perceived the validity of the science (Rooney). While it may be good that people do not immediately believe the things they read on the Internet, they have started to question verified data. In people thinking nothing on the web is true, they consistently try to disprove this data, and anonymously write scathing things about these studies causing other people who see these negative comments to think the research is not professionally done and therefore invalid. This type of anonymity on the Internet forces societies to take a step backwards. Anonymity on the social networking sites brings forth a major negative that has a serious impact on many young adults: cyber bullying. Cyber bullying can be very damaging to adolescents and teens. It can lead to anxiety, depression, and even suicide. 68% – 97% of online aggression victims also experience offline relational aggression and 24% -76% also experience offline physical victimization. Cyber bullying is a gateway for a bully to start abusing others in person. More than 32,000 suicides occurred in the U. S. This is the equivalent of 89 suicides per day, one suicide every 16 minutes or 11. 05 suicides per 100,000 populations (Kersting). With namelessness on the web, people will say anything they want regardless of how it may impact someone else, because they have no fear of being held accountable for the harm it may cause. Anonymity can be used for offensive or disruptive communication. It is not uncommon for people to anonymously say damaging things about other people. People frequently create fake emails in order to make fake profiles on Facebook, so they can publically say whatever they what to whoever they what free of blame or punishment. According to the Cyberbullying Research Center, about half of young people have experienced some form of cyber bullying, and 10 to 20 percent experience it regularly (Bullying Statistics). With the rise of use of social media sites this statistic is growing. As a way to increase awareness, a news station told the story of how someone made a false account and anonymously commented on a boy who was diagnosed with Asperger’s syndrome Facebook saying, ‘You should just go kill yourself. No one likes you, anyway. ‘ The boy, who already faces challenges in school, where kids bully him relentlessly, was smart enough to take this message to his mother and thankfully was given the proper help for him to deal with the bullying and did not take his own life (Finn). Due to the lack of face-to-face contact with the victim, an online bully may not know the effects they are having on the other person. Therefore, online bullies are less likely to feel guilt about the things they have said. In his or her anonymity these kids are more likely to say something even more hurtful through technology then they would normally say to someone’s face (Kersting). These cruel messages are not only free to be seen by any one on the Internet, but they can easily be distributed quickly and to a mass audience, such as a whole student body, leaving the victim with few or no people unaware of the mean, and probably false, comments that are being said about he or she. Making it impossible for the target of the bullying to avoid the negative things that are being said. The ease of access to social allows cyber bullies to attack other people at any time, leaving their victims to feel trapped by the things being said to and about them. It is not like it was for previous generations, where at 3:00 o’clock a person was free from whoever was bullying them at school and could go home to a safe, bully free environment. Social networking allows this generation’s bullies to harass their victims at any time. Because they are attacked round the clock, some victims feel that suicide is his or her only way to be free of the hurt. Someone might argue that for someone who feels suicide is his or her only way to be free of pain that there are plenty of resources to help them. The problem is that a majority of these resources are online, on the very social networking websites where these people are receiving abuse. The resources that will supposedly help them to feel better come from the place that is causing them the most pain, and therefore causes victims of bullying to avoid accessing them. They have the mindset that the social media websites will only cause them pain, making the information unavailable to the people who need it most. In the creation of fake profiles, dangerous people are able to pursue whatever type of target they are seeking. According to Jacob Palme, â€Å"Anonymity can be used to seek contacts for performing illegal acts, like a pedophile searching for children to abuse† (Palme). While there are certain websites that inform people if there is a pedophile living in their area, so they can protect their children from them. There is no such way to warn people of those same hazardous people all over the web, because it is impossible to detect them over the Internet. These dangerous people use anonymity to say what ever they need to in order to get an impressionable person to do what he or she wants. Parents need to have guidelines for how technology is used within the household in order to raise well-rounded citizens that will grow into successful people that will participate in the road to a prosperous society. To have this functioning culture, the community needs children that will grow into adults that are capable of functioning on their own. From a young age, Americas children need to learn about being responsible and not relying on other people or the Internet to gather information For example perhaps have young people share a cell phone that has to be checked out from the parent by the child. This type of rule would require the young adults to be involved in other activities such a reading, sports, or clubs with others and not have the dependence on technology, that so many people ages 18-32 suffer from. Another possible way to monitor social media is have hours of the day where its not allowed. For instance, having to check phones, tablets, and laptops in at night. This will allow kids to connect with people in real life and not just over Wi-Fi. Modern technologies can very well be a double-edged sword, they offer a person an abundance of knowledge at their fingertips, but also can be the cause of intense destruction to another. When improperly used, social networking has an enormous harmful affect on a person’s wellbeing, sometimes even leading to death as stated above. The dependence American culture has on technology is negatively impacting young peoples development. If awareness of the inevitable destruction from the unceasing use of technology does not become more widespread, then American culture has no chance of staying a superpower in the world. People will be in constant fear for what an anonymous person might say about them through social media, hindering them from saying anything at all. The intelligence levels will continue to decline as the use of social media increases and America will be raising a dysfunctional community full of feelings of disconnection and depression. Albert Einstein once famously said, â€Å"I fear the day that technology will surpass our human interaction.

Discrimination Problems

A problem facing human kind that I will start out with is discrimination and racism. For as long as humans have interacted on our planet, there has been discrimination. To me, discrimination is the act of treating individuals unequally because of a group or culture that one lives by. Everyone has been discriminatory at some point in his or her life, sometimes while not even knowing it, but it still needs to be thrown out of our society. In the late 1950†³s, discrimination acts ended against minority groups in a court of law; but did they? Today, some will still say that discrimination against any different type of ethnic group or organization will never just go away. How can a group/organization, educated or non-educated believe that a certain group that they abide by is superior to that of another? And is this still looked at as an acceptable way of living to some, or in some places? An example of an openly racist configuration is the Ku-Klux-Klan. Although most of our country is not supporting such a group, they are still given the right to voice their hatred. How is our nation ever supposed to improve and sustain peace when people are blaming others for something that we have all brought upon ourselves? Another problem I think our humankind is facing is lack of freedom and excess of social control. At this point in my life I am going through a very confusing stage of questioning. Questioning my values, my boundaries, my potential, basically my life in general. Often, I ask myself, â€Å"What the hell were we put on this planet for†? Was it to do what our society is showing us to do? -Or have we all gone completely mad? Who said that we need to succeed and compete, and sometimes make ourselves unhappy to achieve something that we are told is right? Who came up with having our whole world centered at education and goal oriented scholars? Where has the freedom really gone, and what will it lead to-certainly nothing more than what we have now. If freedom is being able to study what one wants and being able to work where one wants, as whatever one wants, these definitions of freedom are still centered around only one way of life-An organized society. True- our world would be beyond chaotic if one should pull the plug on rules, regulations and organization, but has anyone ever brought forth any kind of â€Å"what if†¦ â€Å"?. What would our world be if success and education were not looked at as the â€Å"appropriate and better† way of life? People would be able to live as they choose without the worries of fitting into any kind of society in which they did not want to fit into? What I am asking or yet proposing in a sense is what are we aiming for, and how excessive is our social control going to get? Does anybody have a certainty that what we are doing is in fact correct- if so, I†d like to meet him or her, and have Materialism is another one that I am going to take a shot at. This subject I can†t say I†m exactly fit to write about but it†s something of interest to me, which makes it somewhat of a â€Å"problematic subject† in my book. Materialism to me is our world looking at and making assumptions and opinions about the wrong thing, either the subject being money/success, man-made objects, social upbringing, education or whatever. I have never had a direct problem with materialism only because I have never been confronted or even in discussion with that subject. I grew up in a very materialistic environment and only now am realizing that it is a problem for our society. Where I grew up, in a suburban, upper-class township, everyone forms opinions on everyone by the external view of someone. As I have said above, how much money? Are they attractive? Who are their parents? And so forth. I had never been exposed to anything but that until now, and I am learning that not everyone is like that, so it†s not as much of a problem in some places than in others, although the places with heavy materialistic views and ways of life are not educated enough about this subject to know that materialism is wrong. These are just three of the many things that I think are problems facing human kind in the future and even right now.

Swedish Daddies - Assignment Example This is also to ensure that pressures to comply with the rest of the world by allowing paid paternity leave will reduce chances of employee turnover for those with families (Kamerman, Kamerman and Moss, 2011). The key stakeholders in the dilemma mentioned above include the fathers and the company policy makers and management. The fathers have to choose between working for an organization even without paid paternity leave hence risking their jobs as opposed to risking divorce and leaving their wives to handle everything concerning the baby on their own. This is a tough decision and for those companies without a paternity policy, the fathers just stay in their jobs and work. As for the policy makers and management of the companies that lack paid paternity leave, they risk family-oriented fathers leaving the company and looking for companies that have such policies. They therefore have to think of integrating such a policy. Since money issues will arise, they have to seek assistance from government as well as borrow a few leaves from other organizations with similar policies or simply reduce the paternity leave. Taking paternity leave paid or not depends on the character of an individual. Virtue ethics come to play here because there are those companies with the paid paternity leave but fathers do not take them. Culture is also different in different countries. Countries that are more masculine-oriented do not see the point in paternity leave as the role of child rearing is the work of women (Brandth, et al. 2011). For companies considering whether to establish such a leave policy, they should first think about the culture then think about the virtue ethics which may mean establishing the policy but not making it a mandate for the fathers to take the leave. To however know the virtue of the male employees, research should be carried out and no assumptions made. The

Speech class assignment Essay Example | Topics and Well Written Essays - 250 words

Speech class assignment - Essay Example Audience analysis is essential for gathering situational information. Situational information refers to the context under which a speaker will deliver one’s speech. To begin with, a speaker should know the size of the expected intended audience. This is useful for presentation materials such as visual aids, which the whole audience should adequately see (Hamilton 73). In addition, the speaker should know an audience’s intention of attending a lecture such that one gauges the interest that such people will pay to the speech. Other factors include the audience’s knowledge of a person such that the speaker assesses the trust that one will receive from the audience. In addition, audience analysis is crucial for understanding an audience’s mastery of a given topic. A speaker should be cautious not to overestimate an audience’s comprehension of a subject. This is because the speaker may become too abstract for an audience, which is highly likely to shift attention in case of incomprehensible speech. Such analysis would help the speaker in explaining theoretical concepts entailed in the speech before the actual presentation. On the other hand, presenting a simplistic discussion to a knowledgeable audience may kill its enthusiasm. Audience analysis helps a speaker unravel the demographics of an audience. The demographic factors include ethnic background, age, income status, class, religion, gender, and other related factors. These factors help a speaker articulate a speech in order to address the needs of an audience. It is essential to note that an individual is highly likely to pay attention to a speech that addresses one’s needs. A speaker, however, should be careful not to stereotype an audience because individuals are more complicated than simplistic categorizations. Categorization, therefore, is only important for giving attention to immediate

Overpopulation of Man O war causing reduced fish population Essay

Overpopulation of Man O war causing reduced fish population - Essay Example In the history of man, it has been known that he lived in practically any type of environment. There are those who lived in the wet lands; all they did was to reclaim the land thereby making them habitable. On the other hand, there are those who lived in the deserts; here too, they tried to make them a bit habitable. Man has even lived in the snow in the polar regions and just was the case with the men who lived in the other regions, here too, man tried making it more habitable (Joel, 2004). In the ensuing process of reclamation of the land or the ecosystem to suit the specifications of man, the environment suffers a great deal. The environment, whether very harsh or conducive, is home to other animals. Encroaching on these lands and making them habitable for humans inconveniences the rest of the animals a great deal. The inconvenience may result in the animals reacting in diverse ways; these could be as diverse as some of the animals dying in mass thereby resulting in extinction of species (Kevin, 1998). Man derives his food from his environment. This logical fact is responsible for the diversity that exists in men. Historically, there were esteemed hunters, gatherers, and even fishermen among others. Man depended on his environment more in the pre medieval times when the world was not as developed as it is today. This type of intense over dependencies resulted in more conflict between man and his environment; he never added any value to the ecosystem and to all that lived alongside with him. He tried to make his environment safer for his survival and this resulted in the death of those animals he deemed a threat to his peaceful life. To obtain food, he harvested plants and killed other animals. After making the environment safe and establishing food security for his family, it was eminent that man’s population would increase. Increase in the population of such a domineering animal only meant one thing, more resources would be reclaimed thus more other animals that had previously habited alongside him would be greatly inconvenienced. There would be increased demand for food; this meant that more of the other animals eaten by man would decrease in population. An increase in man’s population means increased demand for land which leads to the most basic need; habitation or accommodation. Consequently, more land is thus reclaimed. One other aspect of man’s life that was quite disastrous to the environment is his belief in ownership. He gets to an environment, grabs some huge junk of land and turns the land his with all that lives in it (Haynes, 2010). This claim of ownership gives him authority over all other animals and plants that live in the land. He is thus free to do with them as he so please even if it means cutting don the trees and killing the animals. The most basic food eaten by man in the history of man is fish, these are small aqua animals that are very rich in protein. This thus made them bearers of great po rtions of man’s implications on the environment. Fish replicates very fast, within five months, a fish is fully-grown and lays eggs, despite this rapid population growth, the fish in the terrestrial regions could not withstand the demand pressure that man laid on them (Thomas & Michael, 2001). The rate of increase of human’s population was alarming furthermore in the terrestrial regions, the commonly existing water bodies that were thus homes

Capital Strucutre Essay Example | Topics and Well Written Essays - 500 words

Capital Strucutre - Essay Example Based on the above assumption, the theory suggest that the firm value is independent of the capital strucutre and there is no fixed combination of the debt and equity which can suggest that it this level the firm has the optimum capital strucutre. However, in practice it is largely believed that the capital strucutre with 60% of debt and 40% of equity can be optimum for the firm. Higher debt capital may fund the growth of the firm however with increasing debt, it becomes hard for the organisations to keep the financial covenants of their debts intact therefore high debt ratios incur further risk for the organistion therefore there is no such magical relationship between debt to book capitalization ratio. The debt to book capitalization therefore vary from industry to industry and there Is no solid formula to determin tha the debt to book capitalization ratio of 60% therefore there is no capital strucutre theory under which it can be justified that a debt to book capitalization ratio should be 60%. A greenfield project is one which is built from scratch and is not constrained by any previous work. These projects are mostly constructed on the unused land where there is no room or need required to remodel the existing piece of land to demolish the existing strucutres. According to the transcation theory of foreign direct investment, the mode of entry into markets especially foreign markets depends upon how efficient the greenfiled projects will be as compared to the domestic facilities. If the greenfield projects are going to give more efficient results than the existing ones than going for greenfield projects can be a good move however if efficiencies are not achieved than in that case greefield projects may go awry. Therefore one of the most important lesson which can be learned from this is the fact that how good greefield projects can bring the desire efficiency and effectiveness in the company specially with relation to the operational efficiency. (Hennart). Apart from that the greenfield projects providethe organisation necessary room to look for better and more efficient resources.  

Social Learning Theory (one of the communication theories) Assignment

Social Learning Theory (one of the communication theories) - Assignment Example For instance, when the behaviour model displayed violent words and actions towards the Bobo doll, the children did the same. The method involved 36 boys and 36 girls. The children were from 3 to 6 years of age. The first group of participants (24 boys and girls) were made to observe a model who exhibited aggressive actions and words towards the Bobo doll. Meanwhile, the second group of the same population were made to watch a non-aggressive model. Finally, the last group was treated as the control batch and had no exposure to any models. The conclusions indicated that the children who were made to observe an aggressive model tended to exhibit more similarly violent behaviors. Interestingly, gender had a significant influence. If the role model was male, the girls showed more physical aggression. On the other hand, if the role model was female, the girls displayed more verbal hostility. However, there is no significant difference between girls’ and boys’ levels of verbal aggression. In addition, boys emulated role models of the same sex more as compared to girls. Bandura furthered that observational learning involves a live, verbal, or symbolic models. This means that exemplars may be live people or animals, auditory directions, or characters that may be seen in different kinds of media such as movies and books. The process starts with attention which entails interest on the part of the observer. After significant amount of attention is paid to the stimulus, retention ensues. This implies that the learner encodes observed information in his memory. Reproduction then happens when the observed behaviour gets replicated by the learner. Motivation comes into play when the observer experiences reinforcement after the reproduction. A learner may repeat the observed behaviour after a reward. Secondly, an individual’s mental condition is essential. Aside from external rewards, internal reinforcement enhances a person’s motivation to pay atten tion to the model. When one can feel and think satisfied as a result of observing, the social learning will be more successful. Thirdly, observational learning does not always lead to a change in behaviour. Novel knowledge can be earned without palpable alterations in one’s actions. â€Å"Social learning theory began as an attempt by Robert Sears and others to meld psychoanalytic and stimulus-response learning theory into a comprehensive explanation of human behaviour, drawing on the clinical richness of the former and the rigor of the latter† (Grusec, 1992, p.776). Though Bandura is most opulently related to this theory, it actually originated from Sears. The history dates back to the time of Sigmund Freud’s psychoanalysis. In 1935, there was a major movement that sought to unify learning and psychoanalytic theories. This resulted to Sears’ focus on socialization as significant aspect of the research. Particularly, he found out that children were being a ffected by the milieu that he encounters day by day. Children adapt the values and attitudes that their parents portray. Bandura agreed with some assertions of Sears but went against some. â€Å"Bandura is clearly the intellectual heir of Sears, influenced by but also reacting against the tradition that Sears represented† (Grusec, 1992, p.776). Together, the two experts utilize learning concepts in explaining how humans develop socially. Sears was more of the

School and Students Essay Example for Free

School and Students Essay Done By: Fariha Khan Yr: 8Australian International School should adopt the year round schooling process for the benefit of students. During long summer breaks, students forget what they have learned. Not everyone likes traveling during the same time every year. Short breaks help receive education and allow students take rests in the perfect time without over pressurizing students. So, adopting year round schooling in AusIS would help students and give better grades to them. In long summer breaks, students mostly forget what they learned the past year. Kid’s memories are not that good and for two-three months breaks, students do not want to review what they learned and usually stay busy traveling, having fun, playing or getting bored at home. If the long summer breaks were made short and spread throughout the whole year, it would help students remember what they learned. â€Å"It is assumed that shorter breaks help students retain information- therefore less time needs to be spent on review,† Kathryn L. Brandy, teacher in the year round school, Jacksonville Florida Times Union. If teachers would review bits of information to students, then they would remember the rest of the information. Long summer breaks would affect all the hard work of students throughout the whole year. So, it would be really helpful to students if the long summer breaks were made shorter and spread through the whole year, by this students will be able to catch up to all the work and help them remember what they learned. Traveling at the same time every year is not something everyone like. Some people like to travel during the winter, because it is cold and you do not get tired from long journeys. Whereas for summer holidays you get tired really fast, and the weather bothers a lot. It is very hot at the time and from the hotness some students catch cold. Many problems occur from the summer vacations which affect the student’s life in all the ways (education, health, and etc. ). So, traveling in the summer holidays wouldn’t be the opinion for everybody. If the year round schooling process would start in AusIS, the pressure of students would reduce and perfect amount of education would be enriched by the students. The long summer holidays are not always fun. It gets boring and even annoying for some people. After a big summer vacation, study starts to push in, and for a long time you are in a very big pressure, until another holiday knocks up. If the break was spread around the whole year, students would get perfect amount of education and a good holiday in the time needed. This would also give the opportunity to the students who do not like to travel during the summer to travel in some other time during the year. So, if the summer vacation would be spread through the year, it would help students get less pressurized and study. Finally, I feel that year round schooling would help students throughout the year. It would be better and come as benefit to students. Many problems are faced by most of the students. Some of the most important counted facts would come to be as students forget what they learned the past year. Traveling during summer isn’t what everybody would suggest or follow. Short breaks lessen the pressure of students and help students to enrich perfect amount of education. As, coming to my point I suggest that AusIS should adopt the year round schooling process which would come as benefit to students in health, education and traveling way.

Jefferson Essay Essay Example for Free

Jefferson Essay Essay Thomas Jefferson played a very important role in the history of the United States. Jefferson is most famously known for writing the Declaration of Independence. Thomas Jefferson talked many times about African-Americans in America. Where they equal to white people? How were whites and blacks different? What about slavery? Thomas Jefferson had an opinion on all of these subjects, but much of what Thomas Jefferson said was later contradicted with his own words. What did Thomas Jefferson mean when he said that all men were equal? Well, many people would agree with what it means today in modern times. Today the statement, all men are created equal means; all men and women whether black, white, tall, short, fat, or skinny were all created equal. That is not necessarily what it meant in the 1700s. Blacks were enslaved and worked hard while wealthy white men did nothing of the sort. Justice Thurgood Marshall said, â€Å"The blacks were so far inferior, that they had no rights which the white man was bound to respect†¦ and that the Negro might justly and lawfully be reduced to slavery for his benefit. This excerpt shows that in that time blacks were not treated the same as whites and clearly did not have the same rights. Conor Cruise O’Brien’s book confirms this belief as he takes a quote from Thomas Jefferson himself: â€Å"It is accepted that the words ‘all men are created equal’ do not, in their literal meaning, apply to women, and were not intended by the Founding Fathers to apply to slaves. † This shows that when Thomas Jefferson talks abo ut all men being created equally he means to say white men. The meaning of the word expatriation is as follows; to leave one’s native country to live elsewhere (Merriam-Webster). Jefferson wanted to send the blacks that were descendent of the original slaves back to Africa. The deal here was Africa was no longer their native country. This act was known as expatriation. The southern courts believed that slavery violated the natural rights of blacks and although slavery was allowed and legal it was immoral and unjust. Thomas Jefferson made it known that he supported the abolishment of slave trading. He said the following to Congress; â€Å"withdraw the citizens of the United States from all further participation in those violations of human rights which have been so long continued on the unoffending inhabitants of Africa. † By this Jefferson means that the people of the United States should stop the enslavement of blacks so that they no longer violate the human rights and stop offending the people of Africa. In this way Jefferson’s reasons for promoting expatriation and understanding for the natural rights of blacks were consistent. He wanted to send the blacks back because he wanted to stop offending the people of Africa. Jefferson believed that blacks and whites were very different. He said that he believed that blacks were originally their own race and became distinct by time and certain circumstances. According to Jefferson blacks came from their own species but were from the same general genus that is the human race. He said that blacks were inferior to whites in mind and body. This can be said to mean that whites were possibly better looking people or that they were more fit. It could have been said to mean that whites were smarter than blacks because they had an education that the blacks did not have. Jefferson did not believe blacks were men. â€Å"Men,† was said to be referred to as only white men. Samuel Eliot Morison says in his book; â€Å"In his views (Jefferson) blacks were not men. † The possession of individual rights was mainly determined by one’s race or skin color. Blacks had no rights early on in the 1700s but began to become free in the early 1800s. A wealthy white male had all rights; he was allowed to do what he wanted so long as it was just. A black man was free and eventually gained simple rights due to the belief that the United States was violating human rights. I do not believe that expatriation could have been a helpful solution to the problem of slavery in America. I believe this because if the slaves would have gone to Africa they would be gone, but there is no saying that the lazy southern farmers would not have brought in slaves from other places. They would have gotten so used to not having to work that they would not be able to start working again. I think that they would possibly keep indentured servants as permanent slaves or enslave poor people. I’m sure that expatriation would not solve the problem of slavery, at least not immediately. As I stated in the beginning, Jefferson’s view changed greatly throughout the course of his lifetime. Later in his life he began to appreciate black people more because of all their hard work. Also, he realized that blacks were the same as whites in that they were to be given human rights and that the people of the United States had been violating their rights from the very beginning. Jefferson also saw that blacks were men, and that really God created all men equal, black and white. Thomas Jefferson certainly lived an intriguing life. He lived during a time where slavery was legal. He lived during a time when slavery began to die out. Jefferson was part of the reason why blacks are free today. Although his beliefs shifted throughout the duration of his life he ended on the good side, the side that was just. He began to believe that all men are created equal with a literal meaning.

Looking At The Future Of Civil Engineering Construction Essay

Looking At The Future Of Civil Engineering Construction Essay It is very important for civil engineers of this generation to understand the responsibility of their profession in the perspective of the environment and society, and in the understanding this responsibility they must try to generate changes in their action and thinking. This can be successful but everyone has to be involved needs to support and encourage the sustainable thinking, this change can come through design and construction processes. Design sustainability is not an easy route as it must be applied in every design theory. Starting from the conception of the design and moving to the location, the structural materials, the structural methods and finally the possible demolition of the project, design sustainability have to be applied in many areas. On the other hand sustainable construction must aim to use less natural materials and materials which are dangerous to the environment, also less energy to cut the amount of the waste and reduce the environmental pollution without negotiating the quality of the project. Sustainable thinking, planning and acting must be involved in civil engineering to reduce the environmental effecting projects have over their whole design life. Only in the course of this process, and by implementing sustainable thinking at every phase in a project, can a set of ideologies to improve the quality of life be created. The economic component of sustainability has been the main driver of projects. As civil engineering considering the sustainability issues we need to consider more than today alone. It is vital to account for cost over a whole life cycle and the impact on the future development. These costs must be considered in tandem with the social consequences and environmental impacts. The social aspect of sustainability is one that has only recently come to the forefront, but has this not been part of the civil engineer`s role for many years. [1] The influence of engineers of the past and present has had wide- ranging social benefits in transportation, natural and physical security, safety, resource management and heritage, all of which improve the quality of life. The social benefits of these are immeasurable but need to be considered together with the impact on the environment and the economy. [1] All the significant factors that go into the design and construction of a project must be judged, making it hard task, but we must all try in order to achieve it. Clearly, it is going to be a long and difficult method before these ideologies are established, since all the information, the assessments and the resources available to both design and construction teams develop continuously but from project to projects it will become easier. The civil engineering profession has an exceptional opening to create a progression of change that will progress and sustain the environment and our planet in the long term. These are the very actions that make civil engineering a distinctive and very important profession for our planet and for our lives. There have been several projects in the UK and around the world, which are known to be the most sustainable building in the 21st century. Their design, development, use of material and the construction is processed and analysed so careful and that they have managed to come out with successful result in all of the following projects. They are known to be the environmentally friendly and economically friendly too. IBN-DLO Wageningen, the Netherlands This building of the IBN-DLO, the institute for forestry and nature research, sets a new standard in people friendly and environmental friendly building. The building, design by architect Stefan Behisch, behaves something like a living organism, with a self-regulation capacity for its temperature and water use, a capacity which responds to the cycles of summer and winter, day and night, heat and cold, rain and drought. This building can adapt and store energy to kick in when they climate changes and it will respond to the change very quickly, this somewhat is very environmental friendly building. The materials used to make this building can be all recycled and reused in there things or other projects. The roofing is made from glass, the frame consist of galvanised steel plus a considerable proportion of extruded alumina. The glass roof has proved to be 70% cheaper than comparable normal custom-made architectural atrium roofs. The wood-framed wall, doors and window are all made from w ood which is glued on to each other rather than they being nailed. The environment advantage of this is that a much larger proportion of the tree can be utilized for quality carpentry work; secondly the amount of frame timber has been kept to a minimum. This is possible because the whole building is made of glass so there is less need of window so less wood is used. an ecological issue. Every nail you dont use goes to the benefit of the environment Stefan Behisch said this during this project. [2] ECOS- Millennium environmental centre BALLYMENA, NORTHERN IRELAND This building is used to show the world that sustainable building is very much possible. Its used as a visitor centre, parkland, environmental information library and offices. Its not only used as museum but its used in everyday life. Its landscape architecture division developed the concept of a visitor centre where the building, displayed and surrounding landscape would be integrated to communicate a central theme of environmental sustainability. These are the methods they used to make their building a sustainable and environmentally friendly building. Heat Conservation and Efficient Heat Distribution Heavy mass structure retention of heat within insulated fabric, low temperature under floor heating distributed trough structural floors, passive solar gains- through south facing glazing and ramp structure, elevated solar absorption of renewable, efficient low energy lighting used where possible and combined heat and power unit fuelled from short rotation willow coppice crop grown on site. Renewable Energy- Predicted Annual Generation Biomass combined heat and power unit, solar water collection, photovoltaic array and predicted energy generation from renewable will be 71% of total predicted energy consumption. Materials Selection Where possible, PVC is not used. Alternative materials were used for electrical conduits and cabling. Plumbing and roof membrane durable and potentially recyclable materials were used; copper, steel, and concrete. Where possible renewable were used, timer stud partitions external timber cladding timber structure and floor. All timber was FSC certified. Use of organic and mineral paints, sustainable landscape management- avoidance of fertiliser and pesticides etc. Environmental Improvements and Town Connections Construction of new pedestrian and cycle path from existing housing and estate to town centre which is increasing bio-diversity through sustainable park management. Creation of habitats through new planting. Retention of existing trees and new lake construction. [3] Matsushita Electric Industrial Co. Ltd Information and Communication Center, Japan, Tokyo The unusually shaped building represents exceptional design in many respects. The trapezoidal structure encloses a huge, 9 story high atrium. Their intension was to blending technology, people and natural ventilation, a waterfall and pond, roughly cut stone walls and rocks, a floor with pebbled surface and stepping stones and some greenery. Matsushita wanted a highly intelligent large scale building, design in amity with nature. They wanted a holistic architecture that would reflect their own technological and environmental concerns. Three most important design solution that were required were The Ireko (or shell space concept) The creation of a heterogeneous indoor environment The use of natural energy systems throughout the building Ireko is the classical concept in Japanese architecture whereby space is approached by considering the layering of one environment within the other and how they and influence one another. The theory behind this classical Japanese architecture concept is to bring nature indoor and integrated into the building as an important interstice. [4] 60L, Australia 60 is the premier green commercial building in Australia, unique in its approach to energy and water consumption, and the use of recycled and re-used materials during construction. It achieved a commercially feasible, healthy, low energy, resource-efficient workplace with minimal impact on the environment. The design of the building and their motive to make this building the most sustainable they used wide range of materials which were new, recycled or re-used in the construction of the 60L. The original building was not demolished but was partially taken apart so that existing resources could be re-used. The bricks, timber glazed partition and the old building structure was re-used. The concrete poured was 60% recycled aggregate, in this situation crushed concrete reclaimed from other buildings. Timber windows and door frames were fabricated from recycled materials, as are the other items such as reinforcing steel and carpet. Most glues, adhesives, sealants and fillers frequently used in building giving off vastly toxic gases. Used of these was minimised wherever feasible. This building is using 50% less PVC than a typical commercial building of the same size and use. Where they used new material they where advised to use renewable materials such as timber, steel, bricks and copper. T hey used appropriate technology, rather than leading edge technology. In 60L case, it has changed the way water consumption in commercial building use to happen and they take a further step in being more environmentally friendly. They minimised the demand for water by providing water efficient fixtures fittings, including water-less urinals and low flush volume toilets pans. They collected rainwater to replace 100% of normal mains water consumption whenever possible. They installed 100% on site treatment and re-use of grey- water and black-water stream to produce reclaimed water for flushing toilets pans and irrigating the roof garden and landscape. Rainfall from the roof is harvested, and then transferred into the holding tanks by the use of a Syfonic system, which uses gravity to produce a siphon effect, which means water transfer is quicker and pipe diameter can be significantly reduced. [5] Finally, through research and understand of this essay I think sustainability and environmental friendly building is not impossible with this economic condition but its a long term program because sustainability and consideration of the environment has come on top of our agenda for past 10 to 15 years while there was major damage down in the past. There is a solution to the problem but this can take lot of time. We are all observers and assistants to the frequent degradation of our local and global environment. Issues such as deforestation, global warming, waste and rising sea levels are all indication to the fact. The management of sustainable construction must integrate the four dimensions: cost, time, quality and the environment. Each of which has local, national, international and global implications. In order to do this communication is required between personal, projects and companies to ensure that lesson learned and the information gathered is passed in and used to address the issue of sustainability. Sustainability is every person`s responsibility and as engineers we have the fundamental role of ensuring projects are intertwined with the reality of sustainability. In doing so we enable the sustainability agenda to be brought to the forefront of the design and delivery of all infrastructure projects in which we are involved. This needs to be from conception to implementation as the f uture of our planet depends on addressing the current issues, ensuring that sustainable agenda is approached and that in all areas it is implemented. The construction industry is traditionally and by its very nature a high usage sector of resources. As an engineer the first introduction to the concept of sustainability was during civil engineering design. As a concept sustainability was easy to define but when it came to the actual application to the project it became more difficult. In achieving sustainable infrastructure we have the chance to use lessons learned over time from innovative high profile sustainable construction projects and to implement new and improved systems of construction to schemes in which we are involved. In the long term everyone is aware that adopting a more mature and active approach to the sustainability agenda is really the only sensible option. I do believe that it is essential that civil engineers address this issue from now and in the future to make our society, economy and environment better and stronger. We are the designers and constructors of the future infrastructure and as such have a greater responsibility to the population and indeed the environment.

Three Types of Happiness Essay -- Happiness Essays

â€Å"Happiness cannot be traveled to, owned, earned, worn or consumed. Happiness is the spiritual experience of living every minute with love, grace and gratitude.† -- Denis Waitley Many people believe that happiness is simply a state of well being; to me, happiness is much more complex. Absolute happiness is anything that brings feelings of pure bliss to an individual’s life. One can gain happiness from simple pleasures of life, such as receiving a kiss from a three-year old, to advanced pleasures, such as a happy marriage or a successful career. Dr. Seligman, a well known psychologist and proponent of positive psychology, identified three types of happiness: pleasant life, engaged life, and meaningful life. Although Dr. Seligman states that the ultimate forms of happiness are â€Å"meaningful life† and â€Å"engaged life†, I believe that â€Å"pleasant life† happiness is just as important. One type of happiness is known as â€Å"engaged life†. â€Å"Engaged life† happiness involves exploring and harnessing one’s strengths and talents to the benefit of himself and society. I experience â€Å"engaged life† happiness when I play my piano. As soon as touch the smooth, ivory keys, I feel an intense surge of joy, and all my surroundings seem to be just a blur; the music soon takes over me, and I am lost in a world of Beethoven, Mozart, and Tchaikovsky. When I am at my piano, all my cares and doubts seem to disappear, and my life seems, at that solitary moment in time, to make perfect sense. Music is my life and my soul. Another type of happiness is â€Å"meaningful life†. â€Å"Meaningful life† happiness, according to Seligman, is the most genuine form of happiness. It is the epitome of life; the point where one feels completely and utterly satisfied... ...† and â€Å"meaningful life† happiness are truer forms of happiness as compared to â€Å"pleasant life† happiness, I stand firm in my belief that the simplistic pleasures one obtains from â€Å"pleasant life† happiness are just as powerful as the joys one obtains from â€Å"engaged life† and â€Å"meaningful life† happiness. My blackberry picking outing enabled me to not only obtain bucketfuls of delectable blackberries but also to spend precious moments of the day with my family, and that, in itself, makes me truly happy.

Lost Characters in Ernest Hemingways The Sun Also Rises :: Hemingway Sun Also Rises Essays

The Lost Characters in The Sun Also Rises In the novel The Sun Also Rises, by Ernest Hemingway, the lost generation is discussed. After the WWI, many were affected in different ways. This post-war generation is described by discrimination, lack of religion, escapism and inability to act. The First character that is introduced into the novel is Cohn. He, as an outsider, is Jewish. Throughout the novel he is looked down upon in one way or another, but already he is separated from the rest which is shown when he is being described: "He had a hard, Jewish, stubborn streak" (p 18). This quote already shows that he is Jewish, and therefore different from the rest. Also, the fact that his streak is `hard [and] ...stubborn" shows that he is hard to deal with or be around. Even thought he is discriminated against, he is one of the very few that inform these people of the `lost generation' exactly how worthless they are when he says to Jake "You know what's the trouble with you? You're an expatriate. One of the worst type... Nobody that ever left their own country ever wrote anything worth printing. Not even in the newspapers" (p 120) and "Hello, you bums" (p50). He literally rubs into Jake's face what kind of a waste he has become once he left his country. It is r ather surprising that the one who is much disliked and discriminated against sees the worthless characteristics of the others. The significance of the word `bums' used must be noticed since a bum is an idle worthless person by definition. This very well describes the `lost generation.' Nevertheless, racism isn't the only separation that the people make. Even the concierge, who one would think would not be too proud, "[takes] great pride in telling me which of my guests were well brought up, which were of good family, who were sportsmen, a French word pronounced with the accent on the men. The only trouble was that people who did not fall into any of those three categories were very liable to be told there was no one home, chez Barnes" (p 60). This shows how important wealth and back ground is, but the ones who are part of the `lost generation' are not included into any of those simply because their background is forgotten, and they are all worthless people.

E-R Diagram

Introduction:- In 1976 ,Chen developed the Entity-Relationship Diagrams ,a high-level data model that is useful in developing a conceptual design for database . An ER diagram is a diagram containing entities or â€Å"items†, relationships among them, and attributes of the entities . The E-R model is one of the best known tools for logical database design. Within the database community, it is considered a natural and easy-to-understand way of conceptualizing the structure of database.Claims that have been made for it include the following: it is simple and easily understood by non-specialist ,it is easily conceptualized ,the basic constructs (entities and relationships) are highly intuitive and thus provide a natural way of representing a user’s information requirements , and it is a model that describes a world in terms of entities and attributes that is most suitable for computer naive end users. In E-R diagram the emphasis is on representing the schema a rather than t he instances. This is more useful in database design because a database schema changes rarely ,whereas the contents of the entity sets changes frequently.In addition ,the schema is usually easier to display that the extension of database ,because it is much smaller Purpose:- Entity-relationship diagrams were first proposed as a means of quickly obtaining, with minimum effort, a good sense of the structure of a database. They are used to plan and design a database and to model a systems data. Key Elements Entities:- * An entity represents the principle data objects about which information is to be collected. * Collective nouns, or nouns, are usually used to name (describe) entities * For example, each person in an enterprise is an entity. An entity has a set of properties, and the values for some set of properties may uniquely identify an entity. For instance, a person may have a person_id property whose value uniquely identifies that person. Entity Set:- * An entity set is a set of entities of the same type that share the same properties, or attributes. The set of all persons who are customers at a given bank, for example, can be defined as the entity set customer. Attribute:- * An attribute is one of the various properties that describe the entity’s characteristics. These properties usually present a single fact – they are atomic. The designation of an attribute for an entity set expresses that the database stores similar information concerning each entity in the entity set; however, each entity may have its own value for each attribute. * Possible attributes of the customer entity set are customer-id, customer-name, customer-street, and customer-city. Domain (value set):- * For each attribute, there is a set of permitted values, called the domain, or value set, of that attribute. * The domain of attribute customer-name might be the set of all text strings of a certain length.Types of attribute in the E-R model:- The attributes used in the ER mo del can be categorized as 1. Simple or Composite 2. Single Valued or Multi Valued 3. Stored or Derived. 1. Simple or Composite * The attribute which are not divided into subparts are called simple attributes. * For example, an attribute customer-id is a simple attribute. * Composite attributes, on the other hand, can be divided into subparts (that is, other attributes). * For example, an attribute name could be structured as a composite attribute consisting of first-name, middle-initial, and last- name. Using composite attributes in a design schema is a good choice if a user will wish to refer to an entire attribute on some occasions and to only a component of the attribute on other occasions. Suppose we were to substitute for the customer entity-set attributes customer-street and customer-city the composite attribute address with the attributes, street, city, state, and zip-code. * Note also that a composite attribute may appear as a hierarchy. In the composite attribute address, i ts component attribute street can be further divided into street-number, street-name, and apartment-number. 2. Single Valued or Multi Valued The attributes that have a single value for a particular entity is called a single valued attribute. * For example, an attribute customer-id is a single valued attribute because for a particular entity it holds a single value. * The attribute that have multiple valued for a particular entity is called a multi valued attribute. * For example, an attribute phone-number is a multi valued attribute because for a particular customer it holds zero, one or several phone numbers. 3. Stored or Derived * Normally attributes are stored attributes, that is, their values are stored and accessed as such from the database. For example, the attributes name, address and date-of-birth of customer entity set are stored attributes. * However, sometimes attributes’ values are not stored as such, rather they are computed or derived based on some other value. This other value may be stored in the database or obtained some other way. * For example, we may store the name, father-name, address of customers, but age can be computed from date-of-birth. * The advantage of declaring age as derived attribute is that whenever we will access the age, we will get the accurate, current age of employee since it will be computed right at the time when it is being accessedFig Symbol used for different types of attributes in E-R diagram An example diagram representing all types of attributes is given below: 1. The attributes empId, empName and dateHired are simple and single valued. 2. The attribute address is a composite attributes because it can be sub divided into street and houseNo. 3. The attribute emp_Qual is a multi valued attribute because an employee has zero, one or many qualifications. 4. The attribute Experience is a derived attribute because it can be derived from the attribute dateHired. 5.The attributes other than Experience are stored at tribute because it can be stored and accessed from the database. Null value:- * An attribute takes a null value when an entity does not have a value for it. * The null value may indicate â€Å"not applicable†Ã¢â‚¬â€that is, that the value does not exist for the entity. * For example, one may have no middle name. Relationship:- * Relationship is a representation of the fact that certain entities are related to each other. * Verbs are usually used to describe relationships. * For example: Students take Courses – Students and Courses are entities, and take is the relationship.Relationship Set:- * Set of relationships of a given type. * For example: students registered in courses ,passengers booked on flight ,parents and their children. Participation: * The association between entity sets is referred to as participation; that is, the entity sets E1, E2, . . . ,En participate in relationship set R. * The participation of an entity set E in a relationship set R is said to b e total if every entity in E participates in at least one relationship in R. * If only some entities in E participate in relationships in R, the participation of entity set E in relationship R is said to be partial.Degree:- * The number of entity sets that participate in a relationship set is called the degree of the relationship set. * A binary relationship set is of degree 2; a ternary relationship set is of degree 3. Mapping Cardinalities (cardinality ratio) :- * Mapping cardinalities, or cardinality ratios, express the number of entities to which another entity can be associated via a relationship set. * Mapping cardinalities are most useful in describing binary relationship sets, although they can contribute to the description of relationship sets that involve more than two entity sets. For a binary relationship set R between entity sets A and B, the mapping cardinality must be one of the following: a) One to one. An entity in A is associated with at most one entity in B, and a n entity in B is associated with at most one entity in A. b) One to many. An entity in A is associated with any number (zero or more) of entities in B. An entity in B, however, can be associated with at most one entity in A. c) Many to one. An entity in A is associated with at most one entity in B. An entity in B, however, can be associated with any number (zero or more) of entities in A. ) Many to many. An entity in A is associated with any number (zero or more) of entities in B, and an entity in B is associated with any number (zero or more) of entities in A. Fig. one to one Fig. one to many Fig. Many to one Fig. Many to many Key :- * A key allows us to identify a set of attributes that suffice to distinguish entities from each other. * A super key is a set of one or more attributes that, taken collectively, allow us to identify uniquely an entity in the entity set.For example, the customer-id attribute of the entity set customer is sufficient to distinguish one customer entity fr om another. Thus, customer-id is a super key. Similarly, the combination of customer-name and customer-id is a super key for the entity set customer. The customer-name attribute of customer is not a super key, because several people might have the same name. * The concept of a super key is not sufficient for our purposes, since, as we saw, a super key may contain extraneous attributes. * If K is a super key, then so is any superset of K. We are often interested in super keys for which no proper subset is a super key.Such minimal super keys are called candidate keys. * It is possible that several distinct sets of attributes could serve as a candidate key. Suppose that a combination of customer- name and customer-street is sufficient to distinguish among members of the customer entity set. Then, both {customer-id} and {customer-name, customer-street} are candidate keys. Although the attributes customerid and customer-name together can distinguish customer entities, their combination d oes not form a candidate key, since the attribute customer-id alone is a candidate key. The primary key is a candidate key that is chosen by the database designer as the principal means of identifying entities within an entity set. * A key (primary, candidate, and super) is a property of the entity set, rather than of the individual entities. Any two individual entities in the set are prohibited from having the same value on the key attributes at the same time. * The designation of a key represents a constraint in the real-world enterprise being modeled. * Sometimes we may have to work with an attribute that does not have a primary key of its own .To identify its rows ,we have to use the primary attribute of related table. this is known as foreign key. * So a foreign key is a field in a relational table that matches a candidate key of another table. The foreign key can be used to cross-reference tables . For example ,say we have two tables ,a CUSTOMER table that includes all custome r data ,and an ORDERS table that include all customer orders . The intention here is that all orders must be associated with a customer that is already in the CUSTOMER table . To do this,we will place a foreign key in the ORDERS table and have it related to the primary key of the CUSTOMER table.Strong and Weak Entities:- * An entity set may not have sufficient attributes to form a primary key. Such an entity set is termed a weak entity set. An entity set that has a primary key is termed a strong entity set. * As an illustration, consider the entity set payment, which has the three attributes: payment-number, payment-date, and payment-amount. Payment numbers are typically sequential numbers, starting from 1, generated separately for each loan. Thus, although each payment entity is distinct, payments for different loans may share the same payment number.Thus, this entity set does not have a primary key; it is a weak entity set. * For a weak entity set to be meaningful, it must be asso ciated with another entity set, called the identifying or owner entity set. * Although a weak entity set does not have a primary key, we nevertheless need a means of distinguishing among all those entities in the weak entity set that depend on one particular strong entity. The discriminator of a weak entity set is a set of attributes that allows this distinction to be made. The discriminator of a weak entity set is also called the partial key of the entity set.The primary key of a weak entity set is formed by the primary key of the identifying entity set, plus the weak entity set’s discriminator. Symbols used in E-R diagram:- Steps in E-R Modeling :- Usually the following five steps are followed to generate ER models 1. Identify the entity set. 2. Identify the relevant attributes. 3. Identify the prime attribute. 4. Find relationships between entity set. 5. Draw a complete ER model. How to Prepare an ERD:- Step 1 Let us take a very simple example and we try to reach a fully o rganized database from it. Let us look at the following simple statement:A boy eats an ice cream. This is a description of a real word activity, and we may consider the above statement as a written document (very short, of course). Step 2 Now we have to prepare the ERD. Before doing that we have to process the statement a little. We can see that the sentence contains a subject (boy), an object (ice cream) and a verb (eats) that defines the relationship between the subject and the object. Consider the nouns as entities (boy and ice cream) and the verb (eats) as a relationship. To plot them in the diagram, put the nouns within rectangles and the relationship within a diamond.Also, show the relationship with a directed arrow, starting from the subject entity (boy) towards the object entity (ice ICE CREAM EATS BOY Well, fine. Up to this point the ERD shows how boy and ice cream are related. Now, every boy must have a name, address, phone number etc. and every ice cream has a manufacture r, flavor, price etc. Without these the diagram is not complete. These items which we mentioned here are known as attributes, and they must be incorporated in the ERD as connected ovals. FLAVOUR MANUFACTURER ADRESS NAME EATS ICE CREAM CREAM BOY PRICE PHONEBut can only entities have attributes? Certainly not. If we want then the relationship must have their attributes too. These attribute do not inform anything more either about the boy or the ice cream, but they provide additional information about the relationships between the boy and the ice cream. FLAVOUR MANUFACTURER NAME ADRESS TIME DATE PRICE PHONE ICE CREAM EATS BOY Step 3 We are almost complete now. If you look carefully, we now have defined structures for at least three tables like the following: BOYPHONE ADRESS NAME ICE CREAM MANUFACTURER FLAVOUR PRICE EATS TIME DATE However, this is still not a working database, because by definition, database should be â€Å"collection of related tables. † To make them connected, the tables must have some common attributes. If we chose the attribute Name of the Boy table to play the role of the common attribute, then the revised structure of the above tables become something like the following BOY PHONE ADRESS NAME ICE CREAM NAME PRICE FLAVOUR MANUFACTURER NAME TIME DATE EATS This is as complete as it can be.We now have information about the boy, about the ice cream he has eaten and about the date and time when the eating was done. Extended Features of E-R Diagram 1. Specialization †¢An entity set may include sub-groupings of entities that are distinct in some way from other entities in the set. For instance, a subset of entities within an entity set may have attributes that are not shared by all the entities in the entity set. The E-R model provides a means for representing these distinctive entity groupings. †¢ Consider an entity set person, with attributes name, street, and city.A person may be further classified as one of the following: a) cust omer b) employee Each of these person types is described by a set of attributes that includes all the attributes of entity set person plus possibly additional attributes. For example, customer entities may be described further by the attribute customer-id, whereas employee entities may be described further by the attributes employee-id and salary. The process of designating sub-groupings within an entity set is called specialization. The specialization of person allows us to distinguish among persons according to whether they are employees or customers. As another example, suppose the bank wishes to divide accounts into two categories, checking account and savings account. Savings accounts need a minimum balance, but the bank may set interest rates differently for different customers, offering better rates to favored customers. Checking accounts have a fixed interest rate, but offer an overdraft facility; the overdraft-amount on a checking account must be recorded. * In terms of an E-R diagram, specialization is depicted by a triangle component labeled ISA, as Figure shows. The label ISA stands for â€Å"is a† and represents, for example, that a customer â€Å"is a† person.The ISA relationship may also be referred to as a superclass-subclass relationship. Higher- and lower-level entity sets are depicted as regular entity sets i. e. , as rectangles containing the name of the entity set. ISA 2. Generalization * The refinement from an initial entity set into successive levels of entity subgroupings represents a top-down design process in which distinctions are made explicit. The design process may also proceed in a bottom-up manner, in which multiple entity sets are synthesized into a higher-level entity set on the basis of common features.The database designer may have first identified a customer entity set with the attributes name, street, city, and customer-id, and an employee entity set with the attributes name, street, city, employee-id, and sa lary. * There are similarities between the customer entity set and the employee entity set in the sense that they have several attributes in common. This commonality can be expressed by generalization, which is a containment relationship that exists between a higher-level entity set and one or more lower-level entity sets.In our example, person is the higher-level entity set and customer and employee are lower-level entity sets. Higher- and lower-level entity sets also may be designated by the terms superclass and subclass, respectively. The person entity set is the superclass of the customer and employee subclasses. * Specialization stems from a single entity set; it emphasizes differences among entities within the set by creating distinct lower-level entity sets. These lower-level entity sets may have attributes, or may participate in relationships, that do not apply to all the entities in the higher-level entity set.Indeed, the reason a designer applies specialization is to repre sent such distinctive features. If customer and employee neither have attributes that person entities do not have nor participate in different relationships than those in which person entities participate, there would be no need to specialize the person entity set. * Generalization proceeds from the recognition that a number of entity sets share some common features (namely, they are described by the same attributes and participate in the same relationship sets).On the basis of their commonalities, generalization synthesizes these entity sets into a single, higher-level entity set. Generalization is used to emphasize the similarities among lower-level entity sets and to hide the differences; it also permits an economy of representation in that shared attributes are not repeated. Difference between Specialization and Generalization No. | Specialization| Generalization| 1| It is a Top Down approach. | It is a Bottom Up approach. | 2| Specialization stems from a single entityset; it em phasizes differences among entities within the set by creating distinct lower-level entity sets. Generalization proceeds from therecognition that a number of entity sets share some common features (namely, they are described by the same attributes and participate in the same relationship sets). | 3| The process of designating sub-groupingswithin an entity set is calledspecialization. | The process of designating groupingsfrom various entity sets is calledgeneralization. | 4| Specialization is a result of taking a subsetof higher level entity set to form a lower- level entity set. | Generalization is a result of taking theunion of two or more disjoint (lower- level) entity sets to produce a higher- level entity set. | .

African Americans in the Civil War

Roman Robinson Kristen Anderson HIST 3060 February 25, 13 African Americans and the Civil War The role African Americans played in the outcome, and the road to the outcome of the Civil War was immense. The fact that the south had slaves and the north did not played an enormous role in the issues. The north wanted to abolish slavery, and the south did not and after the war started this became one of the main reasons for the Civil War. Since most African Americans could not read or write, this made them an easy target, for slavery, against the dominant white man.Once the slaves got to America they started to realize how much trouble they were actually in. The north and the south had a problem brewing, and that was due to the slave uprisings and the run a ways. African Americans played an enormous role in the outcome of the Civil War because of the part they took in it. The civil war, which took place from 1861 to the 1920s, the African American community made tremendous strides toward them becoming apart of America and equals in America. Since they had been controlled by the power of the whites for so long, their independence was extremely unfamiliar to them, with their new emancipation.Since they were so uncertain, they debated about the most effect way to go about actually receiving the rights they deserved. They did not just want to be inferior Negros. Some African Americans thought the actual approach would be to go along with the submissive status the whites held them to, so they could earn their respect until fairness pervaded. Others were more wishful with their thinking and thought the military would make whites surrender and give blacks their basic rights. Those who were still they are thought that no progress would ever come.These blacks decided that it was essential to escape the shackles and cruel attitudes toward blacks. The civil war initially began to save the Union. At the start of the war slave masters were terribly scared that the slaves would r un to join the Union and help the war efforts. To subsidize the problem, most owner enforced harsh restrictions on their slaves. Some owners even moved their whole plantations inland to avoid any contact with the outside northerners. This did not stop the slaves one bit though, this just caused more slave to flee to the north. The slaves that did decide to stay just demanded more freedom from their masters.Some would say the ones that stayed even gained more power; this forced their masters to give them offerings in exchange for work. The issues of emancipation and military service were intertwined from almost the beginning of the war. News from Fort Sumter made African Americans rush to enlist in military units. They were all turned away since there was a law dating from 1792 that kept African Americans from joining the U. S. army. In Boston disappointed African Americans met and passed a resolution that requested the Government to modify its laws to permit them to enlist. Then Lin coln’s Second Confiscation Act was passed.The act stated that, Confederates who did not surrender with in sixty days of the acts passage were to be punished by having their slaves freed. The Militia Act was also passed. This act stated African Americans were allowed to fight in the war. These two acts together thoroughly punished rebel slaveholders. The African Americans that enlisted both fought in the front lines and worked behind the scenes labor jobs. All these rights that the African Americans were receiving inspired them to return home and free their families and friends. Some of them even started living in the plantations that they used to be slaves of.They took them over and began their own cropping. Some of the other plantations had been left to older disabled white woman, when the men had left for the Confederate army. All of this led to the separation of slave labor in the south After trying terribly hard to keep the issue of slavery out of the war, the North decid ed to start enlisting African Americans to help them fight in the war. The Fifty-Fourth regiment was created by the Union Army, and was the only all black unit. This Union in particular contributed to the war efforts of the North and showed a new found power among blacks.The regiment started when John Andrew sent a request to the secretary of war, Edwin Stanton, to create a volunteer regiment of African Americans (3). African Americans from all over the country joined. To help recruit even further they called for help from African American leaders like, Frederick Douglas and William Wells Brown. In just two months over one thousand African Americans, one from at least every state, had enlisted in the regiment. The leader of the regiment would not be black though, they wanted the superior officer to have some certain credentials.The job description posted read: â€Å"Young Man of Military Experience Of firm antislavery principles, ambitious, Superior to the vulgar contempt of color Having Faith in the capacity of colored men for military purpose† (2) The man picked for the job was Robert Shaw. The African American regiment and their captain set off for Beaufort, South Carolina on May 28, 1863 (1). They were to attack Fort Wagner, which was a vital key to Charleston. They only way to storm the fort was to go through loads and loads of Confederates. The sheer size of the Confederates to the Fifty- Fourth regiment was an obstacle in itself.The regiment knew the amount of obstacles they would have to overcome to achieve a victory and yet they kept marching. Shaw and a few men marched to the top of the parapet, and there Shaw was shot and killed. Though this was almost a complete disaster for the regiment they had set a path for future African American soldiers. Frederick Douglas said, â€Å"Once let the black man get upon his person the brass letter, U. S. , let him get an eagle on his button, and a musket on his shoulder and bullets in his pocket, there is no power on earth that can deny that he has earned the right to citizenship. One thousand seventy-nine African Americans had served in the Civil War. They served in both the U. S. Army and about two thousand served in the Navy. By the time the war was over, forty thousand had died in battle and thirty thousand had died of disease and infection. African American soldiers performed all the jobs needed to run an army. They also served as carpenters, chaplains, cooks, guards, laborers, nurses, scouts, spies, steamboat pilots, surgeons, and teamsters (4). There were nearly 80 black commissioned officers (4). Harriet Tubman was the most famous spy; she served for the 2nd South Carolina Volunteers.Tubman decided to help the Union Army because she wanted freedom for all of the people who were forced into slavery, not just the few she could help by herself. And she convinced many other brave African Americans to join her as spies, even at the risk of being hanged if they were caught (4). Am ong Harriet Tubman were many other African American women who served as nurses, spies and scouts. Although, no women were allowed to formally join the army. When black troops were captured by the confederate soldiers, they faced harsher punishments than the white troops.In 1863 the Confederate Congress threatened to punish officers of African American troops and enslave the African Americans, if they were captured. As a result of this, President Lincoln issued General Order 233, which threatened payback on Confederate prisoners of war, if they mistreated African American troops. This order did scare the Confederates a little, but African American soldiers were still treated harsher than whites. In one of the worst examples of this abuse, Confederate soldiers shot to death black Union soldiers, captures at Fort Pillow, TN, in 1864().Confederate General Nathan B. Forrest witnessed it all and did nothing to stop it. The President, Abraham Lincoln, issued the Emancipation Proclamation o n January 1, 1863. This proclamation eventually led to the freedom of all slaves. The document officially made free all bondsmen in the areas of the Confederacy that were still in rebellion. Slavery although was not abolished in the Border States, Tennessee, or the Union occupied areas of Louisiana and Virginia. The proclamation only affected the states in rebellion, so after the efforts it didn’t actually free any slaves.On the other hand, it did strengthen the Northern war efforts, because they knew they were fighting for a cause. Over five hundred thousand slaves had escaped to the North by the end of the civil war. Many of the escapees joined the Union Army, which tremendously increased its power. As a result of the Emancipation Proclamation, the thirteenth Amendment was created. The Amendment created on December 18, 1865, legally freed all slaves still in bondage. The final step the Emancipation Proclamation was to depress England and France from arriving to the war on t he side of the South.England and France wanted to enter the war on the South side, because the South had supplied them both with cotton and tobacco. England and Frances stance changed when they heard that the war had changed to a fight over slavery. Both nations were opposed to slavery, so ended up giving their support to the Union. That led to the winning of the fight for freedom. Juneteenth was the day created to celebrate the emancipation, when the slaves heard about it that midsummer. The holiday is still celebrated today. Abraham Lincoln said, â€Å"A house divided against itself cannot stand.I believe this government cannot endure permanently half-slave and half-free. I do not expect the Union to be dissolved. I do not expect the house to fall, but I do expect it will cease to be divided. It will become all one thing or all the other. â€Å"(3) African Americans along with the rest of the Union were fighting for this freedom and equality that Abraham Lincoln, was talking abo ut. African American contributions were not limited to the role of working the fields in the south or supplying labor for industry in the north.Many African Americans in both south and north participated in either direct or supporting roles in the military. The War Between the States proved to be a war fought for democracy. The liberation that the slaves had been waiting for, recovered the ideas that founded the United States of America. All men were equal under the law. Since, the African Americans made such a persistent effort the changes were made more quickly. Africans pushed for their own emancipation by resisting their masters and other labor tasks.Although a formal Emancipation Proclamation and Thirteenth Amendment freed blacks in America, it would be a long time before they received all the rights they deserved. The minds of Americans had been so engrained with racism only decades of hard work would lessen this.
