Paleozoic Era in the geology of Indiana Essay

Paleozoic Era means â€Å"time of ancient life†. It is estimated to have occurred somewhere around 544 and 245 million years ago. During this time period, the Paleozoic era, there was a great increase in variety and development of life. Animal fauna were abundant during the Paleozoic era. It is a time when different types and forms of plants and animals flourished and became diverse and plentiful. Many with hard shells and exoskeletons appeared. As a result more organisms formed into fossils which left trail of history behind for scientists to study. This era is very important in that is entails an explosion of animal growth in which nearly all living animals appeared and then at the end of the Paleozoic era, during the Permian sub era, suddenly a mass extinction wiped out nearly 90% of all living matter. Much research continues into the reasons why these two extreme situations occurred. (Palmer and Geismann Nov 2002) Subdivisions of the Paleozoic era are; in order of time period most recent to oldest, Permian is also referred to as the age of dinosaurs and Pangea. Pangea was the name when the earth was considered a supercontinent. The majority of the plates had massed together and had just one ocean. The land was relatively dry and had few glaciers. Next came the sub-era, Carboniferous Pennsylvanian (high carboniferous) and Mississippian (lower carboniferous) depicted mostly by the large coal deposits in the area of modern day Pennsylvania with many coal swamps which then spread towards the Mississippi river and became more limestone. The stratigraphy (the study of strata or layers) of the two areas is quite different as a result. This area today called Indiana is in the upper Mississippi River valley. It was mostly made up of Limestone and since sea covered much of the continent at this time, there was a large marine population. Many remnants left over were lime marked by green algae and calcium carbonate which has been eroded and formed by waves and sea water. Then came the Devonian sub era, in which small plants began to appear in the beginning and by the end large trees emerged. Also, tetra pods (considered the first vertebrates to exist on earth) or vertebrates began to inhabit the land. Arthropods (an invertebrate having an exoskeleton, segmented body and jointed appendages), insects and arachnids (eight legged and jointed invertebrate animals in the subphylum Chelicerata) also came about during the Devonian time period. Echinoderms (creature with a limited nervous system) and a wide variety of fish also became plentiful. The Silurian era was marked by great changes in the physical makeup of the earth. The basic climates over the earth stabilized and glaciers and their formations melted and the seas levels rose. As a result, the fish population grew by leaps and bounds. Corals reefs developed and marine life continued to thrive. Freshwater varieties and fish with jaws occurred for the first time. The Ordovician sub era was a period during the Paleozoic era when much of the northern hemisphere as mostly underwater and a large land mass was in the south called Gondwana. The land was moist and had migrated close to the South Pole. It is known for its marine invertebrates and limited plants on land. Glaciers ultimately formed and much of the land froze and formed glaciers. This ended with mass extinction of 60% of marine life. The Cambrian era was considered the explosion where a grand diversity of life on earth boomed all of a sudden. Various types of rock were formed during the Paleozoic era. The earth was six large land masses at this time. Modern day continents were relocated and divided later on. Therefore different rocks and formations existed. Limestone and coal are two examples of rock formed during the Paleozoic era. Sedimentary and Cambrian rock and fossils dating back to the Paleozoic era can be found in the state of Indiana. It was close to the equator during the Pangea and lay in a shallow sea of water. Later as the land changed, sand from the Acadian Mountains washed over the rocks and land in the sea. Mollusks, Crinoids, bryozoans, brachiopods, gastropods, bivalves, which are two half shelled filter-feeders, gastropods (snails) and trace fossils can be found as remnants of that time period in the state. Much of the large amounts of plants from the delta are where the large amount of coal originated from. Plants included ferns, seed ferns, moss and many types of swamp plants which also contributed to the large deposits of coal. Plant fossils from the late Paleozoic era include Lepidodendron, Sigillaria, Calamites, Pecopteris, Annularia and Asterphyllities. (Polly, David 2007) Currently, Indiana is rich in limestone, aggregates (crushed limestone dolomite, sand and gravel), aglime (agricultural lime) and other minerals and rock forms. It also has siliciclastic (made from broken pieces of silica rocks) and carbonate rocks (sedimentary rocks made up of mostly carbonate minerals) and coal. These rocks have all evolved from the Paleozoic era through the rock cycle of erosion, deposition, temperature and pressure. Older rocks are altered and become slightly different and newer younger versions.

Adolescence and Peer Influence

Adolescence is identified as a stage when an individual undergoes a process of growing up in order to become an adult. It involves a process when adolescents experience changes that occur physically and emotionally. Likewise, the whole process could become confusing and uncomfortable for the individual who is at the said phase (de Guzman, 2007). It is believed that many of the younger people who are moving towards the process of adolescence are expanding their ranges in the social life. Likewise, complexities of social involvement also expand. Majority of the teenagers or adolescents are geared towards total independence.As such, the relationship and time of the teenager at home are less frequent (Smetana, 1988; Steinberg & Silverberg, 1986; Noller & Callan, 1991 cited in Jackson & Rodriguez-Tome, 1995, p. 1). Adolescents become more engage in activities that they think represents who they really are. Through this, there is an increase in the awareness of teenagers in their social su rroundings.During the time of adolescence, peers play a substantial role in the lives of young people. Peers become the focus of the teenagers’ lifestyle and most of the activities that they carry out are affected by the peers that they have (Berndt, 1989; Hartup, 1983 cited in Jackson & Rodriguez-Tome, 1995).  It was observed that teenagers begin to build friendships that are intimate in nature, sometime exclusive which often becomes constant unlike the friendships that they have during their younger years. The friendship that teenagers establish serves as an important way for them to develop because for majority of adolescents, peers are avenue where they could freely explore themselves.It is also with their peers that they feel they are accepted and secure. Likewise, the peers that the youths have allow them to exercise things that could uplift there skills which they could later on use for their success (de Guzman, 2007). It was also posted that the social activities th at adolescent have could affect their decisions and interest in participating with sexual relationships (Miller & Simon, 1980; Zani, 1991 cited in Jackson & Rodriguez-Tome, 1995, p. 1).Peer influences are said to be complex in nature. Various studies were carried out in order to understand the influences of peers during the period of adolescence and it was found out that adolescents could acquire positive and negative influences from the peers that surrounds them. In order to further understand the changes that adolescents undergo, it is an imperative to know what peer pressure is and the role that the peers play in the life of young adults (de Guzman, 2007).Peer pressure is identified as the pressures and influences that young adults feel from their social mates (Atwater, 1988 cited in Foreman, 2001, n.p.). It should be noted that peers are those people that adolescents look up to for support and sometimes for approval. Peers are also considered as factors that are inevitable and n ecessary during the adolescence stage. Interaction with peer groups enable adolescents to exercise behaviors that are new to them and serves as a tool for them to develop there social skills which in turn could be used in future interactions (Steinberg, 1996 cited in Foreman, 2001, n.p.).Peer pressure could be present in different domains. While many people tend to believe that peer influences are the reasons why teenagers engage in behaviors that are unhealthy and unsafe, there are many cases when peers influence teens to engage in activities that are positive.According to studies regarding peer pressure, it was reported that many teens are pressured by their friends to engage in activities that are productive. Positive pressures from friends tend to motivate teenagers to engage in activities where they could excel such as athletics, music, community services, various extracurricular activities and other efficient endeavors.In fact, many of the teens claimed that the pressures they get from friends are more positive rather than engaging in the usage of drugs and sexual conducts. It was also supported by many parents that influence from peers posted a positive effect in the school performances of teenagers. Likewise, peers also augment the strengthening of family values. As such, this is a perspective of peer influence that drives adolescents to become well rounded persons and expand their domains in a positive manner (de Guzman, 2007).According to researches, influences from peers are a process where the teens are active recipients. The teens become friends with their peers because of the fact that they already have a lot of things in common which means that peers who enjoy doing things that are similar with their interest tend to gravitate towards each other (de Guzman, 2007). Although there are many instances where diversity could be seen among certain groups, researches also indicate that teenagers are more likely to group themselves according to their sim ilarities.Likewise, it was suggested that teenagers tend to reject people who are different from themselves. These differences could range from physical impairments, or different sets of educational motivation and interests. Nonetheless, the similarities among individuals appear to be an important factor during the socialization process because it serves as a connection for the young adult to create a bond with other people.Due to this, it is believed that teenagers who are not able to have a positive connection with other young adults during the time of adolescence could be at great risk of involving themselves with negative influences from different peer groups. It was perceived that adolescents who fail to establish positive bonds with their contemporaries become more distant and different which make them feel that they are not welcome.In this event, young individuals who received low standards of acceptance are more likely to engage themselves with peer groups who share the same issue. Thus, it is easier to join peer groups that have less positive perspectives. In a greater sense, such groups are often contemplated as those who engage in activities that are anti-social and self-destructive (Pledge, 2003).The point has been made that peer influences could be positive despite of the negative connotations attached to this process of socialization. However, it should be noted that just like positive influences, peers could also brought about negative influences that could reinforce the adolescents decision of engaging in risky behaviors.Risky behaviors were identified as actions that could produce outcomes that could be damaging physically, mentally and socially (Jessor, 1992 cited in Smith, 2001). Several types of risk behaviors include engagement in sexual activities, substance abuse, cigarette smoking and crime activities. Adolescent behaviors could be altered by peer group influences through verbal and non-verbal means.Verbal pressure that is done directly is the most common way of getting compliance from the young adult. For example, a certain peer group may not impose an adolescent to smoke; however, the members of the group may say things like â€Å"you are such a baby,† â€Å"just try it nothing wrong is going to happen† which could insinuate the adolescent to smoke in order for him or her to look better in the eyes of his or her peers.Meanwhile a non-verbal persuasion could be done by staring at the adolescent for a long time until he or she feels uncomfortable which in the end is more likely to succumb in performing the behavior (Duryea, 1985 cited in Smith, 2001).Aside from verbal and non-verbal methods, peer pressure could also be seen in different forms. The pressure could take the form of challenges or dares, social acceptance and coercion and the influences could also vary depending on the age and gender of the adolescent (Hayes and Hofferth, 1987, p. 105).Sexual activitiesThere are limited researches that li nk peer influences in the early acquaintance with sexual activity. However, it was consistently presented that peer influence is an important factor that greatly affect the initiation of sexual activities among adolescents.It was also suggested that the major source of sexual information are from same sex-peers (Libby and Carlson, 1973; Miller, 1976; Thornburg, 1978 cited in Hayes and Hofferth, 1987, p. 105). Likewise, an adolescent who believes that their same–sex peers are sexually experienced and the liberal approach of his or her peers regarding sex are indicators that the teenager is more likely to engage with sexual activities.Thus, it was contemplated that majority of the teenagers actually engage in activities based from the perception of his or her peers attitudes and behaviors even if it is correct or not (Newcomer et al., 1980 cited Hayes and Hofferth, 1987, p. 105). Some findings indicate that white male teenagers choose their peers in accordance to sexual activit ies that were carried out by the individuals within the circle while their black counterparts were neither influenced by the behavior of their friends or choose peers on such particular basis (Billy and Udry, 1983 cited Hayes and Hofferth, 105).Meanwhile, female adolescents could be persuaded to some extent based from their knowledge of what her female friends are engaging into yet it was manifested that adolescent girls are strongly influenced to practice the sexual act by their â€Å"best male friends† and sexual partners (Miller and Simon, 1974; Herold, 1980, Cvetkovich and Grote, 1980; Billy and Udry, 1983 cited in Hayes and Hofferth, 1987, p. 105).Moreover, it was found out that among adolescents age 10 to 14, the pressure in sexual involvement could be done through challenges and dares to the extent of fondling, kissing or even intercourse. Such occurrence is prevalent among girls (Lewis and Lewis, 1984 cited in Hayes and Hofferth, 1987, p. 105) while only minor peer in fluences were recorded among black teenage boys and girls (Billy and Udry, 1984 cited in Hayes and Hofferth, 1987).Generally, white girls are more at risk of involving themselves with sexual activities due to peer pressure (Hayes and Hofferth, 1987).Substance abuseAside from sexual activities, it was reliably demonstrated that peer groups also play an important role in influencing the decisions of adolescent to initiate the usage of drugs and alcohol. Likewise, it was also recorded that peers also affect the decision of the teenagers to reject, continue experimentation or augment the usage of drugs and other substances (Bauman & Ennett, 1996; Darling & Cumsille, 2003 cited in Hankin and Abela, 2005, p. 366).As adolescent marks the development shift of young individuals towards the path of maturity, it is within the same period that adolescents tends to increase their involvement with peers and is the beginning of the experimentation stage with drinking and smoking (Flory, Lynam, Mil ich, Leukfeld & Clayton, 2004; Sutherland & Shepherd, 2001 cited in Hankin and Abela, 2005, p. 366).As such, this strongly manifest that the involvement of an adolescent with a peer group is a substantial factor that contribute to the initial experimentation of drugs and other substance use. Moreover, various theories also point out that there is a strong relation with peer influence and initiation and escalation of substance abuse.Two notable theories are the Peer cluster theory (Oetting & Beauvais, 1998 cited in Hankin and Abela, 2005, p. 366) and the Primary socialization theory (Oetting & Donnermeyer, 1998 cited in Hankin and Abela, 2005, p. 366) indicates that normative and deviant social behaviors are the results of the interaction of characteristics that are cultural, social and psychological in nature. Thus, behaviors like smoking, drinking and drug usage are learned from the adolescent’s interaction with their peers.Crime activities  As it was said, the formation o f peer groups is an important part in the development process of a young adult. Such formation may be viewed as a way of an individual to attach themselves with people whom they think they could share who they really are. One of the peer groups prevalent nowadays are adolescent gangs. Although adolescent gangs are considered as peer groups, it is contemplated as a group comprised of young individuals whose behaviors are perceived negatively by the society.As such, adolescent members of gangs tend to engage in activities that are violent and anti-social (Geldrald K. and Geldrald D., 2004, p. 36). Based from researches, adolescent gangs are accounted for a large number of crimes in the urban setting. Many adolescent tend to engage themselves with this type of peer groups because they believe that this is an avenue for them to be accepted and freely express themselves.Because of these reasons adolescents see gang membership as an option for them to build their identity in any way possi ble whether it is wrong or right without thinking of the consequences.This is when peer pressure could be viewed as extremely powerful because adolescents who are members of gangs are more likely to engage themselves with risk like poor reputation, death, delinquency, substance abuse, infliction of transmitted diseases and early parenthood (Snyder, 2001).According to researches the very reason why many adolescents are vulnerable from the negative influences from their peers is because of the feeling of the need to belong in a particular group. Such needs lead many adolescents to take part in activities that could put them at risk. For majority of adolescents the need to belong to a particular peer group is an achievement of self-actualization and an attainment of the so called â€Å"maturity† and establishment of identity (Benthin, Slovic & Severson, 1993 cited in Smith, 2001).ConclusionBased from the facts that were presented in the study, it is apparent that peers play a si gnificant role in the lives of adolescents. Peer groups provide teenagers the feeling of belongingness and security. The influences of peers among adolescent could bring about positive end results which are actually important for the development of young individuals. Such positive influences from peers create a ground for adolescents to become well rounded people.Nonetheless, peer could also encourage negative influences among adolescents. The negative influences of peers may take the form of risky behaviors such as engagement in sexual activities, substance abuse and crime activities. It is also important to note that adolescents who are vulnerable to the negative influences of peer groups are those individuals that are not able to form connection with positive peer groups.Therefore, it is suggested that young individuals who encounter failures with forming bonds with peer groups should be taken into consideration in order to know the factors that affect their social involvement wi th other individuals. Moreover, it is also suggested that further analysis regarding the impact of peer influences should be investigated in order to further understand some of the points that were not presented in the study.

Achieving Happiness

Nowadays we believe that if we are wealthy and have material possessions we would be happy and content with our lives. Is this really the case, how does money and materialistic items help us achieve happiness? If we look at celebrities, athletes, or individuals who possess large sums of wealth and material possessions we believe they are the happiest individuals; that they have everything and buy anything. However, are they really content with their lives? In Gretchen Rubin’s book The Happiness Project, she explains that to be happy it must come from inside oneself; you must do the things you love, have fun, freedom, be positive, and most important that inner drive to push you on the right track in becoming happy. Rubin realizing she was in danger of wasting her life gave herself a year to conduct a happiness project; to not only become happier, but also to be more satisfied and content with every life. Every month she completed a different set of resolutions to help her along the way. Nonetheless, Rubin was innately motivated to achieve true happiness and had that inner drive to change old habits and create new ones. Moreover, the methods Rubin used to become happy relates to Daniel H. Pink’s book Drive. Pink helps us understand whether or not happiness comes from outside sources or is it within oneself to make the change. His study on extrinsic forces such as money or material possession implies that these only keeps people happy for a short period of time; on the other hand intrinsic forces such as ones inner drive is a greater force than outside influences. Rubin also used intrinsic motivation to commit to her happiness project and commit to her daily habits. Charles Duhigg defines habit as â€Å" Charles Duhigg’s book The Power of Habit explains how we human beings can change addictive habits or create new and healthy ones. Rubin created and changed habits such as, keeping a low temper, and having more fun. Her overwhelming happiness rubbed off on others and ultimately changed the atmosphere around her house and friends. This emotional contagion relates to Lauren Slater’s text book Opening Skinners Box: Great Psychological Experiments of the Twentieth Century where she explains two cientists John Darley and Bibb Latane’s who conducted an experiment to test the reaction of a naive subject; and if that naive subject attempted to aid themselves or others when something disastrous or out of the ordinary occurred. Rubin’s intrinsic motivation based on Drive, her creation of her habit loop and changing of habits explained by Duhigg, and social imitation based on Darley and Latane’s smoke experiment motivated her to change her habits, and become happier and content with her life. Gretchen Rubin was a mother of two young beautiful daughters, seven-year old Eliza and one-year old Eleanor. She was married to a handsome man named Jamie who loved her as much as she did. Rubin lived in New York City and was a full time writer. However, one April morning Rubin was sitting on a bus looking through rain spattered windows when realized she was in danger of wasting her life. She did not feel happy; she had everything: a loving husband, a loving family, two beautiful kids, friends, wealth, but she did not feel happy. Rubin describes â€Å"I wasn’t depressed and I wasn’t having a midlife crisis, but I was suffering from midlife malaise† (2). This midlife malaise was a sense of discontent and feeling of disbelief that she could not do and accomplish anything. As a result of being frustrated and unhappy, Rubin started her own happiness project; every month she set out 4 to 5 resolutions she wished to accomplish by the end of the month for one whole year. These goals led her to intrinsically motivate herself to start a long and dedicated track towards happiness. During the month of January she was dedicated to boost her energy and vitality; she had five resolutions to accomplish during that month: going to sleep earlier, exercising better, organizing her entire house, tackling a nagging task, and acting more energetic. Furthermore, these resolutions had to rely on being intrinsically motivated to complete them. Pink defines intrinsic motivation as â€Å"that enjoyment-based intrinsic motivation, namely how creative a person feels when working on the project, is the strongest and pervasive driver† (21). Her 2nd goal during January was to exercise better; however, her father used extrinsic motivation to try to make her exercise. Rubin says â€Å"with extrinsic motivation, people act to win external rewards or avoid external punishments† (22). As a result Rubin never became too fond of exercising on her own; only when someone forced her to she would. However, with this exercising goal, she inertly motivated herself to try to exercise every day; she did this to make herself feel better, boost energy, and look better. Studies show that when someone feels and looks better; they will be much happier with the way they look and feel. At the end of January Rubin was off to a promising start; she had been intrinsically motivated to become happier and rewarded herself with a check mark on her resolution chart, which made it easier for her to be motivated and stick with her happiness project. All the resolutions Rubin followed during every month were mostly habits that had to be developed. During the month of April, one of her resolutions was to sing in the morning. This was where instead of lashing out on her kids or husband as she used to do, she would try to sing their mistakes or complaints and make them laugh. This took extreme discipline for Rubin, because it was a habit of hers to attain a quick temper and lash out on her kids or husband. This is where the habit loop and golden rule of habit change comes into play. Duhigg defines the habit loop as â€Å"a loop which consists of the cue, routine, reward; cute, routine, reward becomes more and more automatic† (19). The cue is the trigger that tells your brain to go into instinctive mode and which habits to use† (19). Secondly, the routine is the action or addiction itself, it can be done mentally, emotionally, or physically (Duhigg 19). Lastly the reward is the pleasure and satisfaction in executing a habit. Rubin’s cue before her habit change was when her husband or kids complained about anything such as, when Rubin was changing Eleanor’s diaper and Eliza was complaining that she had not eaten her breakfast (Rubin 95). Her routine whenever this complaining occurred was lashing out or getting upset and lastly her reward was silence or the job getting done. According to Duhigg, the â€Å"golden rule of habit change is only achievable if you use the same cue; provide the same reward, but modify the routine to successfully change the habit† (62). Her new habit to sing in the morning changed her previous routine of lashing out to sing her child’s or husbands complaint and make them laugh and have silence. The cue was still the complaining and the reward was still silence or getting the job done. Rubin describes â€Å" One morning Eliza whined ‘why do I have to go to class today? I don’t want to go to tae kwon do ,’ I wanted to snap back, ‘ you always say you don’t want to go, but then you have fun,’ or ‘I don’t like to hear all this grumbling. ’ instead, even thou it wasn’t easy, I sang out ‘ I on’t want to go tae kwon do’† (96). This type of mentality in dealing with kids or spouses increases happiness and helps marital and child relations. This habit change allowed Rubin to not only deal with problems in a positive way, but also allowed her to spread happiness in an easy, but effective manner. Moreover, another habit that Rub in changed was during the month of June; she always had a problem with gossiping. However, one of her resolutions for that month was to stop gossiping all together. To obtain long term happiness, you must give up something that brings short term happiness; such as gossiping (Rubin 155). This short term happiness of gossiping is increasingly fun for social functions, but it is not a nice thing to do and whenever you say critical things about other people the spontaneous trait transference occurs. The spontaneous trait transference is a psychological phenomenon where people unintentionally transfer traits to the people who ascribe them (Rubin 156). For instance, if I was to tell Josh that Bill is ignorant; Josh would believe I was also ignorant. As a result Rubin wished to stop. Furthermore, her cue before stopping was an urge or a juicy story, the routine was talking excessively about it and lastly the reward was the happiness and satisfaction she gossiped. Moreover, she stopped her gossiping by replacing the routine with either walking away or defending the person individuals were talking about. Rubin shares an experience â€Å"I was at a meeting when someone mentioned of mutual acquaintances, ‘I heard that their marriage was in trouble. ’ ‘I hadn’t heard that,’ someone replied. So fill us in was the implication of her tone. ‘Oh I don’t think that’s true,’ I said dismissively. Let’s not talk about that was the implication of my tone† (155). Furthermore, two scientists John Darley and Bibb Latane conducted an experiment to test whether or not human beings are driven by social imitation. To test this they brought in three college students; two as actors and one as a naive subject and told them to fill out a questionnaire on college life. A few minutes into the experiment, nonhazardous smoke began to flow out from vents and captivate the room. The two actors continued to fill out the form, but the naive subject was more interested in the heavy smoke pouring out like cream. Slater describes â€Å"The confederates were instructed to keep filling out their forms, to display no fear. They did. The smoke started pouring like cream, coming faster, heavier, smearing the air and blotting out figures, faces. The smoke was an irritant and caused one to cough. Each time, the naive subject looked alarmed, looked at the smoke going from wisp to waft, looked at the calm confederates, and then, clearly confused, went back to filling out the questionnaire†(104). The results were extraordinary; the naive subject imitated the actors in the room, doing nothing about the smoke. Slater described â€Å"we are driven by imitation† (IDK). This experiment shows that we are driven by social imitation; copying other people to please ourselves and feel comfortable rather than feeling out of place. However, can this be related to happiness? Rubin described â€Å"a phenomenon called ‘emotional contagion’ is unconsciously catching emotions from other peoplewhether good moods or bad ones (127). Thus, social imitation and emotional contagion are the same; For example, we all have that friend that has a â€Å"contagious laughter†. Why do you think that is? Well, because of that friend’s continuous laughter, everyone else in the group may start to inexplicably feel the same way, sometimes without even realizing what is causing their reaction. During May, one of Rubin’s resolutions was to take time to be silly. Even though controlling her temper by singing complaints had done wonders, Rubin wanted even more happiness around her home. She wanted to create a happy atmosphere. One day while putting groceries away, Rubin used two clementine’s to make goggle eyes at her two daughters; not only making her laugh, but her whole family as well. Since, Eleanor and Eliza saw her mother laughing at her silly joke, they also joined in. This was exactly how the naive subject reacted when he saw the two confederates ignoring the smoke. Instead of reporting the smoke as an emergency, the naive subject also ignored the smoke. Moreover, social imitation or emotional contagion also played a role during the month of June when one of her resolutions was to make three new friends.

Manifest Destiny - Essay Example The increase in population of the initial 13 Colonies and the growth of the United States economy increased the desire to grow into additional land. The Manifest Destiny concept tremendously influenced the United States policy. This enhanced the American expansion to the West. The idea was largely put forward by posters, newspapers and other avenues. Despite the fact that it was not a formal policy of the government, it facilitated the passing of legislations like the Homestead Act, which promoted colonization and acquisition of areas in the West (Robinson 2010, 21). Additionally, the idea was a factor in the thought of America. Movement into the West regions provided a prospect for self development. To be familiar with the concept of Manifest Destiny, it is essential to comprehend the desire and need of the United States to expand. This paper will look at how issues around it affected the U.S, how the views of Americans on the issue changed over the period, and will also mention some events as examples. John OSullivan, a U.S newspaper editor writing on the planned occupation of Texas, was the first to use the term in 1845. He asserted that it was America’s â€Å"manifest destiny to spread to the whole continent.† The newspaper issue recommended that through expanding, America could turn out to be a renowned superpower. According to OSullivan, United States had been exclusively selected for the mission of Westward expansion. This would push out the wilderness and bring civilization. Between independence and 1920, the government passed land laws that were favorable for people to migrate. The federal government also persuaded people from Europe to come and inhabit. It used the military to protect the settlers from natives. It further put money into explorations, such as that of Clark and Lewis. Wherever there was sufficient water, homesteading was practiced by people from the Midwest to the Pacific regions. Cheap and available land,

Role of HR in Knowledge Management Research Paper

Role of HR in Knowledge Management - Research Paper Example Most of the organizations do not effectively utilize Human Resources’ contribution for the effective implementation of Knowledge Management. If people are managed effectively and their knowledge utilized efficiently, then evidently it can become a competitive advantage. Relying on modern information systems will be fruitful if people are actively involved in knowledge sharing. The different areas of Human Resources which help in effective knowledge sharing are reward systems, recruitment, retention, succession planning and training and development. The first and most obvious area of Human Resources involvement in Knowledge Management is reward management. It is very clear that employees will not be ready to share their knowledge and expertise until and unless they are rewarded. Rewards will motivate them to share their knowledge and it is purely on the shoulders of Human Resource people to undertake this task. This way H R enables knowledge sharing in different departments. In case of recruitment, retention and succession planning from a Knowledge Management perspective can be looked at as filling knowledge gaps. While recruiting new employees, they can select candidates who are more creative and innovative and can adapt themselves to the changing work environment. Also, retention of good employees is necessary. The HR policies and procedures should be designed in such a way that they allow employees to meet their personal objectives. Succession planning, on the other hand, is about planning to meet future skills and knowledge needs with existing resources. Human Resources’ involvement and its contribution is perhaps the greatest in training and development. Human Resources should get itself actively involved in the technological developments in the workplace as they can train the employees accordingly. Training is necessary for individuals to work in teams as co-operation and sharing of information brings in benefits for the whole organization. T hough Human Resources’ contribution is inevitable in the area of Knowledge Management, it has certain limitations as Human Resources and other departments are most in conflicts. This can be seen as a limitation of Human Resources’ intervention in effective Knowledge Management. Employees in other departments need to support the HR people for effective knowledge sharing as HR people becomes the mediator in knowledge sharing. This is not Human Resources’ role alone but its contribution is necessary. Building a culture for Knowledge management on certain values will require changes in systems and processes, and a way of doing things which both transmits the organizational culture to new employees and reinforces it to old employees. As with any change situation, conflicts can arise. This is where Human Resources can contribute to the development of the Knowledge Management culture by handling such conflicts. According to Chivu and Popescu (2008),  in terms of know ledge migration, Human Resource may play a major enabling role in helping identify the potential of knowledge migrants.

The future of AIS - Essay Example AIS is an automatic system of tracking the ships on high seas. Shipping, has been known for many centuries as a formidable industry in itself and as a crucial means of propagating many other trades and industries. This mode of transport is one of the most dangerous as well. Therefore shipping industry calls for improved safety standards. Vessel traffic systems (VTS) uses AIS for identifying the vessels, exchanging data/ information and taking due precaution in case the vessel appears to be indulging in some suspicious activities. AIS is one of the most reliable standards adopted by the International Maritime Organization, a specialized agency under the aegis of United Nations. IMO is responsible for improving maritime safety and prevent pollution from ships. During the times of fog or at night on the high seas, AIS helps in easily identifying the ships from a safe distance and thus avoids any possible accident. Though ships are also equipped with radar for identifying and exchanging signals during navigation, but there happen to be some zones known as blind arcs or shadows, where AIS proves to be very helpful. Generally a vessel equipped with AIS will display the information relating to; Within the usual radio range of 15-20 nautical miles, the Automatic Identification System can process up-to 4000 reports per minute (Desvignes et al, 2002). With the help of such information AIS can help in collision avoidance, safe navigation, ships routing, automatic reporting, search and rescue operations, security screening, and traffic analysis. To make all these things possible AIS facilitates (Capt McCabe, 2007): Ship to ship identification and information exchange: This helps in taking evasive actions, collision avoidance etc/ Ship to shore identification and information exchange: This helps in taking adequate steps for anchoring the ship. The ship sizes, type of material on board the ship requiring delicate handling etc are all taken care of during such information exchange. Short safety related messages (SSRM)L During the times of emergency brief messages about the difficult state of the ship can be broadcast to nearby shores and ships. Binary messages (texts): Binary text message for particular recipients can also be transmitted. Aids to navigation functions: Existing AIS could provide navigational aid in the form of information about the nearby vessels, places etc. Meteorological and hydrological information: To certain extent the expert system can also forewarn the ship about the weather conditions ahead, so that adequate precaution can be taken. Differential GNSS services: It makes use of differential navigation techniques combined with GLONASS and GPS, collectively referred to as Global Navigation Satellite Service (GNSS). Search and rescue
