Performance Management Paper - Essay Example Coaching can be very effective in eliminating workplace conflicts, cementing relationships and having teams focus on their core work hence achieve the set objectives. To effectively coach my team, I will focus a lot on developing interpersonal skills and improving interactions instead of developing individuals. This is because the way individuals act and communicate with each other are crucial factors that drive effective performance in the team. One guiding principle in my team training therefore has to be team work, learning to work with colleagues and understanding to relate with others. To begin off, I must understand team dynamics; it is obvious that all of us have our own ways of working and communicating hence one can really be frustrated if not understood by colleagues. The objective is to have team members come together, discuss their personal profiles and assist them devise means to work together. Once managers understand this then they definitely do the same even with the junior most employees. Another guiding point in team training is establishing behaviour expectations; understanding the perspectives of others can greatly improve performance and relationships. But there must be some ground rules guiding the team members as they work to accomplish set goals. Having a very clear behaviour code and communication expectation is thus very important. Another key point of training is evaluating rewards and recognitions systems. It is very common for values held by different individuals to compete and hinder effective performance in teams. As the manager, it will be my role to determine any sources of competition in values and devise ways to fix the same. Supporting individual performance is another essential point in team coaching as some members may require to be supported in learning new skills so as to meet team expectations. Readiness for

Learning Disabilities Why Self esteem Essay Example for Free

Learning Disabilities Why Self esteem Essay As a child goes through teenage life, he or she is exposed to many different challenges, stressors, and prospects. An imperative factor in handling these challenges is a positive self-concept and high self-esteem. Through teenage life, schools should be preparing students to become a comfy part of the general population, quickly bending to their environs (Saghatoleslami, 2010). A population of students that necessitate closer attention are Learners who have been diagnosed with a learning disability. Learners with learning disabilities are likely to represent 2% to 10% of the student population (Reese, Bird, Tripp, 2007). Learners with learning disabilities tussle with self-concept and self-esteem, which in tum can lead to amendment difficulties, substance abuse, depression, and suicide ideation. It is, therefore, essential to monitor the self-worth of students and help mend and advance their self-concept and self-esteem. When bearing in mind students with learning disabilities, it is important to weigh their self-concept and self-esteem in a different way, understanding different social factors that come into play (Moller Pohlmann, 2009). There are many facets to self-concept and self-esteem, and coping with a learning disability has an influence on a students quality of life. For both students with LD and students who have not been diagnosed with LD, active parental involvement can directly influence a students self-concept and self-esteem (Saghatoleslami, 2010). The Individuals with Disabilities Education Act, Public Law, splits 12 types of categorizations of learning disabilities, in which children may be fit for special education and interrelated services. These types are; (a) autism, (b)deafness, (c)deaf-blindness, (d)hearing impairment, (e) mental retardation, (f) multiple disabilities, (g) orthopedic impairment, (h) severe emotional disturbance, (i) visual impairment, (j) speech or language impairment, (k) traumatic brain injury, (l) and specific learning disability (Moller Pohlmann, 2009). Autism is an age-linked disability significantly affecting verbal and non-verbal communication and social relations, typically evident before age three. Deafness is an earshot impairment that is so austere that the child is lessened in processing linguistic info, with or without augmentation; deaf-blindness is a synchronized visual and hearing impairments. Hearing impairment is of the audible range, whether perpetual or mutable. Mental hindrance rel ates to suggestively below usual general cerebral functioning, which prevail concurrently with shortfalls in adaptive performance. Multiple disabilities: the exhibition of 2 or more disabilities such as mental retardation-blindness, an amalgamation that involves special accommodation for ultimate learning (Moller Pohlmann, 2009). Additionally, there are corporal impairments; orthopedic impairment is physical disabilities, which include congenital impairments, caused by illness, and impairments from further causes (Berdine, 2010). Grave emotional disorder is a disability where a child of typical intellect, has strain over time and to a patent degree, building pleasing interpersonal relationships; (a) retorts inappropriately psychologically or emotionally under ordinary circumstances; (b) exhibits a pervasive mood of unhappiness; (c) or has a propensity to develop physical signs or fears. Detailed learning disability is a malady in one or more of the basic psychosomatic processes convoluted in understanding or in expending language, written or spoken, which may patent itself in an imperfect knack to speak, read spell, think, write, or do mathematical calculations; dialogue or language impairment: a communication (Moller Pohlmann, 2009). Disorder such as stuttering, impaired articulation, a type of linguistic i mpairment, or the voice impairment can be considered a detailed learning disability. Traumatic brain injury is an assimilated injury to the brain caused by a marginal physical force, resulting in partial or total functional disability or psychosocial impairment or possibly both (Berdine, 2010). Visual impairment is a pictorial struggle (including blindness) that, even with correction, unfavorably affects a child educational performance. Learning disabilities can disturb students in diverse manners. As studies designate, self-concept and self-esteem are two vital elements during a students foundational years. Throughout this time, students begin to express and realize who they will turn into as grownups. The self-concept that is established during this time canines over into maturity (Elbaum Vaughn, 2010). For this purpose, it is vital to consider the adverse effects of LD, especially during a teenager life. Dyson points out that children who have proficient denial, disgrace, and disappointment have outlooks of low self-worth and defenselessness (2008). Both students with LD and students without LD exhibit varying levels of self-concept and self-esteem. These self-concepts adapt and grow as a student develops from childhood, through adolescence, and into adulthood. Students with LD reported that they felt worse about their general intellectual ability than students without LD (Moller Pohlmann, 2009). This can result in negative self-concept and low self-esteem. By implementing evidence-based interventions, students with LD can develop a positive self-concept and improve their self-esteem. One such response includes positive parental involvement. When parents are involved in the lives of their children in a positive way, the self-concept and self-esteem of their child improves. A challenge of active parental involvement pertains to the difficulties of communicating with a child who has LD (Dyson, 2008). Utilizing parental programs to overcome such adversities positively affects the parent/child relationship. Through this active inte raction, adolescents with LD improved academically and emotionally. A lot of children with LD get these emotions more often than students with no LD. This can have a philosophical effect on their educational self-concept as well as their general self-esteem. The importance of this topic is substantial, as the American Psychiatric Association (2007) establish that between 3% and 8% of the learners’ population, especially children are affected by LD. Utilizing the Self-Perception Profile for teenagers, Moller and (2009) established that high school learners with LD conveyed they felt worse about their general mental ability than did students not diagnosed with LD. Furthermore, using the Piers-Harris Childrens Self-Concept Scale, it has been shown that students with LD scored significantly lower on the subscale of Intellectual and School Status. This is significant because these students were in separate classes with other students in special education (SPED), including students with emotional disturbances or cognitive impairments. When students are deliberately taken out of the general classroom, it becomes apparent to them that they are different from typically developing students. By separating students, it can have an adverse effect on their self-concept. This can have an adverse consequence on their self-esteem and academic achievement (Ochoa Emler, 2007). The response to this unruly is not as easy as moving towards an inclusive system where students with LD learn with typically developing students. In a study shepherded by Barrera, it was revealed that the self-concepts of students with learning disabilities attending comprehensive schools were inferior to those of their classmates devoid of learning disabilities (2009). The discoveries are all too shared, since a meta-analysis prepared by Barrera established the same incongruity (2009). Due to these common judgments, many schools have relocated away from an integrative class. In other situations, the self-concepts of students with learning disabilities may be improved through adapting instruction to the wants of each student (Elbaum Vaughn, 2010). Constructing the best erudition environment for each student wishes to be a precedence within the overall school system. Once students with LD associated themselves with others with LD, they conveyed that they felt improved about their recital than children with LD, who likened themselves to their aristocracies without LD (Ochoa Emler, 2007). This largesse contradictory information. When unraveling students with LD from archetypal students, it can have an undesirable consequence on their self-concept and self-esteem. On the affirmative side, nevertheless, when students with LD are studying with other students with LD, they may incline to compare themselves to their partners with LD. This outcome in a more optimistic self-concept and advanced self-esteem in students with LD. Every school is exclusive in its tactic to students with LD, and it is significant to consider these educations when determining whether or not students with LD should be encompassed in the general classroom or placed in a distinct studying setting. Age is an imperative factor in appreciating what the best intervention is for a stu dent with LD. While academic interventions were most consistently effective for elementary students, counseling interventions were the most reliably effective for middle and high school students (Elbaum Vaughn, 2010). These results have an effect on the academic self-concept for the student and do not necessarily hold true for other dimensions of self-concept. Elbaum and Vaughn also pointed out that, overall, counseling and mediated interventions were the only interventions that had a significant effect on general self-concept (2010). These findings complement previous statements regarding the importance of creating an intervention strategy that is malleable, as well as unique to each student who passes through the intervention plan (Reese, Bird, Tripp, 2007). To create a single intervention strategy, it may be useful for a school to use the interpersonal competence profile. By using the ICS-T and the ICS-S and comparing the two, a unique strategy can be created for each student that best serves his or her learning style. This tool can be useful to determine if an inclusive or separated intervention strategy would best help each student with LD. The insight provided by Berdine; because self-knowledge emerges from, and is sustained by, our experiences with others, negative self-views have interpersonal as well as personal components (2010). This means that for people to enjoy improvements in their â€Å"self-views†, changes must occur not only in the way they think about themselves, but also in the environments that sustain their own self-views (Berdine, 2010). The value of this quote is substantial. Not only is this positive self-concept paramount for students with LD, it is also significant for everyone. Our experiences in life and our perception of who we are define what we eventually become. In Positive Teacher and Parental Involvement, it is important for teachers and parents to affect the self-concept and self-esteem of students with LD by remaining positive and encouraging them to succeed. This is evident, as it was exhibited that there was an incongruity between self-assessments of students with LD and their ed ucators verdicts. They discovered that students alleged themselves to be more proficient than their teachers rule on them. Furthermore, Moller and Pohlmann (2009) indicated that teachers were commonly unaware of students perceptions of abilities. For better communication between teachers and students, it may be beneficial for tutors to devote time to students to converse their perceived strongholds and weaknesses. When parents were positively involved in the lives of their children, the self-concept of their children was affected in a positive way (Ochoa Emler, 2007). The students paternities can also petition or appeal to the learning institution, or to the director of distinctive education and complain of their child being gaged. They may sense that the child is not developing as he, or she ought to be, or identify or detect certain glitches in how the child does. If the school believes that the child, undeniably have a disability, then the school must perform a valuation. If conservatory staff do not sustain that the learner has a disability, they may well decline to consider the child, but should apprise the parents in lettering as to their whys and wherefores for rebuffing. If parents believe intensely that their child does, certainly, have a disability that needs special edification, they may entreaty a due process earshot, where they will have the chance to spectate why they believe their juvenile should be appraised. To be assessed, there are numerous of probable assessments that are acknowledged in the IDEA, that is, Individuals with Disa bilities Education Act (Elbaum Vaughn, 2010). When parents interacted and maintained, a positive attitude with their children, a more positive self-concept was developed and self-esteem was raised (Berdine, 2010). Conversely, when the interaction between parent and child was minimal, or family communication was poor, negative self-concept and low self-esteem resulted. Dyson (2008) found that children with LD themselves can contribute to a lack of communication between child and parent. In line, child and parental cognitive-behavioral factors reciprocally amplify one another over time. For parents of high school students with LD, communication was often directly related to the nature of the learning disability (Berdine, 2010). When a parent and child were unable to communicate wholly due to the childs disability, it adversely affected the relationship. This alone is reason enough for parents of children with LD to explore various options for the betterment of communication with their children. When this lack of communication comp ounds over time, stress can be built up for the child as well as the parent. If the guardian of a child with LD exhibits stress surrounding their childs disability, that child tends to have problems with social competence as well as display more behavior problems (Dyson,2008). This presents a direct correlation between parental stress regarding a childs disability and the self-concept and behavior of that child. When parents show a positive environment for their child with LD, it helps to reinforce a sense of positive self-concept and high self-esteem. Children with LD have a strong academic self-concept and high self-esteem when they receive positive feedback from teachers and parents (Dyson, 2008). When children have a healthy self-concept, they are less likely to have a low self-esteem (Reese, Bird, Tripp, 2007). To determine if a child is adequate for classification in one of these regions of exceptionality, an individualized appraisal or valuation, of the child must be carried out. This is accomplished through IDEA. The IDEA stipulates a number of requirements regarding estimates of children alleged of having a disability. While a more comprehensive description of these requirements is presented in the Persons with Disabilities Education Act, these rations are briefly summarized as follows: In advance a child is evaluated for the first time, the school district must acquaint parents in writing (Berdine, 2010). Parent’s commitment gives written consent for the school system to carry out this first evaluation also identified as a pre-placement appraisal. Evaluations must be accompanied by a multidisciplinary team such as speech and dialectal pathologist, occupational or physical therapist, medical specialists, and school psychologist. They must include at least one teacher or sentinel who is knowledgeable about the area of the childs alleged disability. The assessment must carefully investigate all areas related to the childs suspected impairment (Dyson, 2008). Indeed not a sole technique may be used as the sole norm for determining a childs eligibility for special services or for deciding his or her suitable educational placement. Moderately, the evaluation method must utilize a variety of valid evaluation instruments and observational data. All testing must be done independently. Trials and other evaluation materials must be delivered in the childs primary language or manner of communication, unless it is evidently non-realistic genuine to implement. All tests and other evaluation resources must be authenticated for the particular drive for which they are used. This tells that a test may not be used to evaluate a student in an exact area unless the test has been premeditated and validated through examination as measuring that definite area. Valuations must be conducted in a fair way. This means that the trials and evaluation resources and procedures that are the castoff may not be ethnically or culturally prejudiced against the child (Mon tgomery, 2011). The assessment team must guarantee that any test used is administered correctly by a person fitted to do so, that the test is being used for the objectives for which it was meant, and that the childs disability does not conflict with the childs ability to take any test measuring specific abilities, the childs visual impairment changes his or her ability to read and rightly answer the questions on an test. Suitable, comprehensively, and accurately assessing a child with an alleged disability clearly presents a substantial challenge to the assessment team (Dyson, 2008). Valuation in educational locales serves five main purposes: (a) screening and proof of identity: (b) to screen children and recognize those who may be experiencing delays or learning problems; (c) eligibility and diagnosis: to govern whether a child has a disability and is entitled to special education amenities, and to analyze the specific nature of the students glitches or disability;(d) IEP growth and placement: to p rovide comprehensive evidence so that an Individualized Education Program (IEP) can be enhanced and proper decisions may be implemented of the childs educational placement; (e) instructional scheduling: to develop and plan instruction apt to the childs individual needs; and evaluation: to assess student development. (Berdine, 2010). One program that was used to influence parental/child interaction positively was Systematic Training for Effective Parenting (STEP). (Barrera, 2009) Used STEP to deliver parents with training on how to answer more positively to their children. The outcomes displayed that parents had a very strong influence on their childrens self-concept. Additionally, Barrere suggested that classroom interventions to augment self-concept might be enhanced by involving parents in a synergistically designed parent program (2009). As previously mentioned, students with LD are more likely to struggle with social competence (Dyson, 2008). Having active parental involvement in the life of a student with LD helps facilitate improvement in this realm, thus positively influencing a students self-concept (Dyson, 2008). Intervention strategies for students with LD within the school setting resulted in underwhelming outcomes at times. To better the chances of success, schools may see benefits by involving paren ts in their intervention strategies. When parents interacted with their children frequently, positive outcomes generally occurred. As Reese, Bird, and Tripp (2007) found parent-child conversations regarding positive past events contained the highest amount of emotional talk regarding the child. Additionally, during conflict discussions, a moderate amount of positive talk was found. This positive talk can have a profound effect on the self-concept of a child. The link between conversations regarding past positive events and childrens self-esteem was substantial (Brown Hooper, 2009). In Critical Analysis, there were three main research questions addressed in this studies: (1) what is the dissimilarity stuck between self-esteem and self-concept? As the constructs of self-concept and self-esteem share similarities, it is important to delineate the two constructs in order to depict their differences clearly. Self-concept is defined as peoples overall composite or collective view of themselves through multidimensional sets of domain-specific perceptions. These judgments are based on self-knowledge and evaluation of value or worth of ones competences formed through involvements with and understandings of the environment. A persons self-concept not only comes from internal individual perceptions, but can also be influenced by different experiences and external information from others. Peoples self-concept addresses a more factual side of their life, such as knowing what they enjoy or what they tend to think about themselves. Self-esteem, as defined by Ochoa and Emler, is the sense an individual has about himself or herself that affects the way he/she views himself or herself (2007). These opinions include self-observations, perceived feelings of him/herself, and self-knowledge. How the individual feels is addressed within self-esteem, whereas self-concept addresses what the person thinks or sees about himself or herself. Self-concept is a construct that stays relatively constant over time, while self-esteem can vary throughout a persons lifetime (Berdine, 2010). (2) How do students with learning disabilities and scholars who have not been established with a learning disability compared in regards to self-concept and self-esteem? Present study endorses that there is an alteration in the levels of self-concept and self-esteem between students who have been detected as having learning disabilities and students who have not been analyzed as having a learning disability. Barrera, (2009) established that high school students with LD reported that they felt worse about their general Intellectual ability than did students who have not been diagnosed with LD. Students with Learning disabilities who were in separate classes with other students in SPED, such as students with emotional disturbances or cognitive impairments, were found to have a lower self-concept on the Intellectual and School Status subscale. This finding suggests that the separation of the individual with a learning disability from the general education classroom can have an adverse e ffect on the students self-concept. Comparatively, Brown and Hooper (2009) showed that students with learning disabilities attending inclusive schools had a lower self-concept than classmates without a learning disability. Whether students are included in the general education classroom or separated and placed with other students with disabilities, their self-concept was consistently lower than that of students without disabilities (Montgomery, 2011). It is important to note the research that the self-concepts of students with disabilities can be heightened through tailoring instruction to the needs of the individual student. According to Saghatoleslami when students with LD compared themselves to other peers with LD, they felt better about their performance than did children with LD, who associated themselves with their peers without LD (Saghatoleslami, 2010). These findings suggested that pairing students within the general classroom on the basis of instructional level and individual needs positively influenced the self-concept and self-esteem of pupils with learning disabilities. (3) Does the level of active parental and teacher involvement have an effect on a students self-concept and self-esteem? According to the existing research, active parental and teacher involvement has a positive impact on students self-concept and self-esteem. Dyson (2008) found that children with LD have a positive academic self-concept and high self-esteem when they receive positive feedback from teachers and parents. The environment the parent provides, as well as the dialog between the guardian and the youth, are both factors that play a role in the students development of self-concept and self-esteem. For instance, Dyson (2008) found that if a parent of a child with LD exhibits stress surrounding their learners disability, that child tended to have problems with social competence as well as display more behavior problems. When parents presented a positive environment for their child with LD, it helped to reinforce a positive self-concept and a sense of high self-esteem. Addition ally, communication was often related to the nature of the learning disability, especially when the parent and the child were not able to communicate due to the childs disability. This, in turn, adversely affected the relationship between a parent and child (Ochoa Emler, 2007). It was supported that with positive interaction and a parents positive attitude toward their children, a more positive self-concept was developed and self-esteem was raised from the child (Montgomery, 2011). The emphasis is a positive interaction and support from the parent to positively influence self-concept and self-esteem. Along with a positive stress, there is also a weight on alliance between the home and school to upkeep consistency between the two settings. Saghatoleslami (2010) found that active parental involvement in a wellness-based prevention program in schools was helpful in building positive self-concepts in children and college students. Additionally, Montgomery, (2011) suggested that classroom interventions used to increase self-concept might be enhanced by involving parents. The involvement of parents or other supportive figures, bettered the chances of success across settings, as there were collaboration and communication occurring between parents and teachers. A limitation of the analysis is the broadness of the subjects. While there is an assortment of LD types, there was no sub-typing of LD in this study. Furthermore, self-concept and self-esteem were measured on a broad scale, with minor sub-typing of self-concept. Socioeconomic status, ethnicity, gender, and physical attractiveness were not taken into consideration when measuring a students self-concept or self-esteem(Dyson, 2008). Finally, this studies are not applicable across cultures. The vast majority of research reviewed was conducted in the United States. Based on the analysis, it is clear that the most complex measure of self-concept and self-esteem is necessary. In future research, obtaining more data regarding self-concept and self-esteem will make additional subtypes available, both for these two domains, as well as subtypes of LD (Reese, Bird, Tripp, 2007). Further implementations need to be aimed at supporting students with LD. The focus of future support for students with LD should be not only academic, but have emotional and psychological support as well. Many interventions are aimed at improving the grades of students with LD. In addition to this, specific attention should be placed on the betterment of their self-concept, as well as the improvement of their self-esteem. Both teachers and paternities should be included in future studies to promote positive self-concepts and increase self-esteem. Through in future studies, effective evidence-based solutions will be found. References American Psychiatric Association. (2007). Diagnostic and statistics: manual of Mental Disorders.

A history of hand gestures

A history of hand gestures In this paper I will talk about the part of nonverbal communication called gestures. A gesture is a movement of the body or a part of it that is expressive of thought or feeling. However there is a degree of voluntarism. If someone pinches you and you flinch that is not a gesture. (Kendon, 1997) Gestures are a common part of communication that we all use to communicate everyday and most of us do not even think twice about using them. As gestures can include a wide range of things a narrower focus is required. For this paper I will be focusing on gestures specifically involving the use of hands and/or fingers. First I will talk about research done on gestures. Second I will talk about the interaction between gestures and verbal language. Lastly I will apply the use of gestures to personal friendships using , examples from an episode from the television show Smallville. Research Let us first consider primates such as apes and chimpanzees. Primates are mostly visual animals. Just as in humans, for primates vision is more highly developed than any of the other four senses including the sense of sound. Consider for a moment what this might mean. Primates, with the exception of humans, have much better cortical control over hand movements than over voice, which is mostly restricted to emotionally based sounds controlled by sub cortical structures. This means that early hominids would have been better at expressive, voluntary communication using hands. Perhaps this explains why it is much easier to teach higher level primates sign language than it is to teach them to speak. One early study showed that a chimpanzee raised by humans could learn to speak only three or four words but gorillas and chimpanzees have learned several hundred manual signs. (Corballis, 1999) However primates other than humans are restricted in using hands for communications because the arms and hands are also involved in postural support and locomotion. Most primates are adapted for living above ground in the tress. Apes live on the ground but move in a four legged fashion. Our closest genetic relatives, chimpanzees and gorillas, use what is known as knuckle walking in which the upper body is supported by the knuckles. Hominids are bipedal, walking upright which leaves their hands and arms free. (Corballis, 1999) There is speculation that the split that resulted in some great apes becoming hominids may have been caused by the formation of the Great Rift Valley in Africa. Those apes which were to become hominids were largely confined to the east of the valley. The discovery of a 3.5 million year old fossil in Chad which is west of the valley has caused some argument. However all other hominid fossils from between four million and two million years ago have been found to the east of the Great Rift Valley. Here the forests gave way to open grasslands called savannas. This new environment would have provided unique challenges for early hominids. They would have been vulnerable to specialized hunters and killers, the ancestors of tigers, lions, and hyenas. In this environment communication using gestures would have been much more effective than vocal communication. It is silent so predators are not alerted. It is also fundamentally spatial, and most of the information would be spatial, such as loc ations of predators, easy prey, or food. The earliest language being gestural would help explain how words came to be abstract rather than iconic. (Corballis, 1999) A leading figure in gesture research is psychologist Susan GoldinMeadow who has done several studies about the role of gestures in learning. It is a well established fact that students learn better if both words and hand gestures are used. Consider for example a teacher trying to illustrate water being poured into two containers of equal volume but different heights. The teacher will place one hand on top of the other and move them to illustrate differences in height. (Watts, 2006) Context We do not always gesture when we speak. Also the type of gesture, the role in relation to what is being said, and the role in relation to the situation vary. If you wanted a person to stay away you would not use a gesture telling them to come closer. Someone of the other gender gesturing for you to come closer has different meaning then if it is done by a friend or parent. If you are talking about a fish you caught you will hold your hands apart horizontally versus if you are describing how big a baby has gotten your hand would be vertical. (Kendon, 1997) Just like language gestures are not uniform to a culture or country. In the United States you wave your hand to say hello and goodbye. If you were in northern Europe you would wag your hand at the wrist. In Greece and Italy your palm would face inward and your fingers would be curled in. In Japan you bow slightly. How long and how deep you bow depends on the person. Lets go back to my earlier example of a gesture that means to come here. Here we curl one finger, usually the index, or all four fingers towards us. In the Philippines do not use the index finger. It is only used for dogs. In Latin America the index finger is a come on. In Indonesia and Australia its used for prostitutes. In southern Europe using all your fingers would be saying goodbye. In Korea you would hold your arm out and move your fingers up and down. If someone puts their hand out in front with the fingers outspread here it means stop. In Lebanon it means no. If you were in Greece its a curse. In Spain, Nigeria, a nd Chile it also has rude meanings. In the United States you typically point with your index finger to someone or something. In Europe pointing is not considered polite. In Africa you only point the index finger at inanimate objects. In China and Japan pointing is very rude. In Indonesia pointing with your index finger is very rude but you can use your thumb. In Zambia it is all right to point to objects. And In France if you do point it is best to do it discretely. (Kachka, 2008) Some gestures are country specific. In the Netherlands grabbing a nonexistent fly in front of your face is saying someone is nuts. In Poland flicking a finger against someones neck means you want them to join you for a drink. You only do this with close friends. In Russia giving someone a thumbs up and making a sprinkling motion over it means job well done. In India you say sorry by tapping someone on the shoulder and touching your forehead. In Turkey pretending to throw salt over your shoulder with an open palm means dont worry about it. (Kachka, 2008) Just like words gestures have their own origins. But since gestures predate verbal communication and thus written record the origins are difficult to trace. This does not keep people from speculating. Here is a myth behind a common gesture; the Roman emperors thumbs down gesture telling the gladiator to finish off the other gladiator. Todays popular culture has it that a thumbs down meant death while a thumbs up would grant the loser his life. There is no evidence of this. In fact most scholars now believe that the finish him gesture was a thumbs up while a thumb hidden inside a fist spared the loser. This is not absolutely verified. However since the thumbs up was an insult in Roman times this makes more sense than the accepted folklore. (Kachka, 2008)Application Now we will exam hand gestures in friendship. To do this we will be examining an episode of the CW show Smallville. As you might guess this show centers around the character Clark Kent played by actor Tom Welling. The series follows Clark as he deals not only with his developing powers and fighting meteor freaks (people exposed to Kryptonite who gain special abilities) but also school, friends, and crushes. Clark has two best friends, Pete Ross and Chloe Sullivan. The episode we will be focusing on is the episode Duplicity in which Pete finds out Clarks secret. The other notable characters in the episode include Clarks parents, Lex Luthor, and Dr. Hamilton. After Lex refuses to give Dr. Hamilton, who is dying from exposure to meteor rocks, any more funding for his research Dr. Hamilton runs someone off the road. Pete comes along and while helping the man comes across Clarks spaceship which was lost in a tornado in the season one finale. Pete gets Clark to help him hide it in his shed although Clark tries to get him to leave it but cant come up with a logical reason. Dr. Hamilton talks to the hurt driver in the hospital who admits he saw a spaceship and that the boy who saved him saw it too. When Clark tells his parents about Pete finding the spaceship his father makes him go with him to get the ship. But when they get there it is already gone. They drive away and Pete sees them leaving. When Pete confronts Clark he shows Pete his powers. Furious that Clark has been lying to him for so long Pete leaves. Clarks attempts to talk to him are rebuffed. But when Pete goes home Dr. Hamilton is searching the shed and Pete is kidnapped. Hamilton tortures him to see what he knows about the ship. Just as he is about to kill Pete by injecting him with meteor rocks Clark bursts in. Unfortunately he collapses due to the Kryptonite. Pete saves him by pushing Dr. Hamilton into a shelf full of meteor rocks. After they return the ship to the Kents cellar Pete says he understands why Clark and that he wont tell anyone. We will examine three scenes from the episode: the scene where Pete gets Clark to come with him to the cornfield, the scene in the cornfield where they are talking about what to do with the ship, and the scene where Pete confronts Clark about the missing ship and Clark reveals his powers. When Clark is shooting baskets from a hundred feet Pete drives up. â€Å"Clark, Clark, Clark. Youre dreaming if you think youre gonna make a basket from there.† Pete makes an exaggerated pointing motion towards the basketball hoop. â€Å"No, no, no. The ball rolled out here.† Clark makes a waving motion to indicate the spot. â€Å"Want to play a game of horse?† â€Å"Forget basketball. We gotta borrow your dads truck.† Pete makes a waving motion with one hand. â€Å"For what?† â€Å"Ill explain on the way. Come on, we dont have much time.† â€Å"Whats going on?† Clark holds his hands out at this side with palms turned out. â€Å"If I told you, youd never believe me.† Pete places his palms on his chest when he says. â€Å"You gotta see it with your own eyes.† Pete puts his hand on Clarks shoulder urging him to move. Pete leads Clark to the spaceship clapping his hands together and making trumpeting sounds. â€Å"Pretty mind-blowing, huh?† He gestures to the ship with his hand. â€Å"What do you think it is?† â€Å"Oh, Clark, its a spaceship!† Pete motions to the ship again. â€Å"What the hell else would it be?† Pete waves his arms in a questioning gesture. Kneeling down beside the ship Clark says, â€Å"Well, I mean, I dont know if it was some, like, downed specialty aircraft or a Russian satellite or something.† After he says this Clark also motions to the ship. As Pete kneels down beside the ship and runs his hands over it, he says â€Å" No, no, no. This things got extraterrestrial written all over it.† â€Å"Yeah, I bet theres little green guys running around the cornfield too, Pete.† â€Å"Im serious, Clark. Have you ever seen anything like it?† Pete spreads one hand palm out and motions to the surrounding area with the other one. â⠂¬Å"If the aliens came to Earth, dont you think theyd find a place a little more exciting than Smallville?† â€Å"No, no, no, think about it. Crop circles, cattle mutilation. Theyd be like kids in a candy store here! Come on, man, lets load it into the truck!† Pete waves his arms wildly at the surrounding area. Then he grabs the ship. Clark moves to stop him. â€Å"Wait, youre not just gonna take it.† â€Å"Clark, when the sheriff questioned me about the accident, I told him in all the confusion I couldnt remember where the truck went off the road. But its only a matter of time before he shows up. Come on. Come on!† When talking about the sheriff Pete spreads his arms with palms out and then motions to the ship. â€Å"All right fine. Well take it to my house.† â€Å"No, no, no, Clark! I know your dad. Hell make us turn it over to the authorities.† Pete puts his hand on Clarks chest with the palm out. â€Å"I wont even tell him. He wont know its there.† Clark spreads his arms out with his palms out. â€Å"Clark, were taking it to my house. Well hide it in the tool shed in my backyard. No one ever goes back there.† â€Å"Pete, my house would be perfect. Itll be safe there.† â€Å"Clark, last time I checked, I found this thing. Youre acting like you got license and registration on it, man. Lighten up. Were taking it to my place.† When Pete says† I† he places his hands on his chest. When he talks about Clark owning the ship he flips his hand out towards him. When he says †lighten up† he holds his hand up with his palm facing out and his fingers spread. When he says† my place† his hands are yet again on his chest. â€Å"Pete. Hey, I was just gonna come talk to you.† â€Å"Really?† â€Å"Yeah, about the ship† â€Å"Oh, someone broke in to my shed last night and stole it.† Pete holds his hands out palms up. â€Å" â€Å"Really?† â€Å"Yeah.† â€Å"Well, did you tell anyone it was there?† No, did you?† â€Å"No, my lips have been sealed.† â€Å"Youre such a liar.† â€Å"What do you mean?† â€Å"I saw you and your dad driving away from my shed last night.† Pete motions to Clark. â€Å" All night long I kept telling myself theres gotta be some sort of logical explanation. Clark Kent would never do anything like this.† Pete holds his hands out slightly with the palms facing out. â€Å"Pete, I swear we didnt take the ship.† Clark spreads his arms holding his hands out with the palms spread. â€Å"And all these years I used to think you were my best friend.† Pete motions to Clark again and starts t o get into his car. â€Å"Pete, wait. You dont understand.† Pete turns around and says holding his arms out slightly at his sides with palms facing out, â€Å"What dont I understand? Go ahead, explain it to me, Clark.† Clark doesnt know what to say. â€Å" Thats good, really illuminating. Wait till Chloe hears about this. I can already see the headlines. The Real Clark Kent Exposed!† Clark puts his hand on the car door. Pete starts to drive away. Clark watches him drive away and waves his arms then he appears in front of the car holding it to stop it from moving forward. â€Å"Pete, we need to talk.† The screen fades to black and then they are in the cellar talking. â€Å"So youre some sort of what? Youre not a human?† Pete holds both hands out at Clark with his palms facing each other. â€Å"I dont know what I am.† Clark spreads his arms with his palms facing out. â€Å" I dont know where that ship brought me from. I just know that I grew up in Smallville, and everything that I care about and everyone that I care about is here.† Clark motions to the surroundings and to Pete. â€Å"If you care about me so much, how come you never told me sooner?† â€Å"Pete, believe me, there wasnt a day that went by where I didnt want to tell you, but my parents thought it was too dangerous. Not just for me, but for anyone else who knew the truth.† When Clark says â€Å"you† he gestures to Pete. â€Å"You didnt think I could handle it?† Pete holds his arms out to Clark. â€Å"Can you?† Pete starts walking around Clark looking at him like hes an exhibit in a museum. â€Å"Pete, another reason why I didnt say anything is because I knew people would look at me the exact same way that youre looking at me right now.† â€Å"And hows that?† † Like a freak.† Pete motions at Clark with his palm facing up. â€Å"Pete, Ive tried my whole life just to blend in, to try and be mor e normal than anyone else. Would you just say something? Call me call me an alien, call me a monster. I dont care, just say something.† â€Å"Its like I dont even know you.† Yet again Pete motions to Clark. â€Å"Yes, you do know me. Im the same kid that used to camp in your backyard.† Clark motions to Pete. â€Å" We used to ride our bikes in the woods, we used to play basketball with your brothers. Nothing has changed.† â€Å"Yeah, right.† Clark holds his hand out and steps towards Pete, â€Å"Pete.† Pete backs away and waves him arms. â€Å"Back off, man!† â€Å"Pete, I would never hurt you.† â€Å"Too late.† Pete walks out. Conclusion Gestures are a part of nonverbal communication that movement of the body or a part of it that is expressive of thought or feeling. Gestures were used by primates as communication before verbal communication was developed and primates are much more able to learn sign language than verbal language. Early hominids would have found gestures much more useful than verbal communication for avoiding predators. There is evidence to support that both gestures and verbal language are required for effective learning. Gestures vary depending on the role in relation to what is being said, the role in relation to the situation, and the cultures in which they are used. There are many example of gestures in the media and one of those is the television show Smallville. Ponder this information the next time you have a conversation. It might be useful.

The Great Gatsby :: essays research papers

The Great Gatsby by F. Scott Fitzgerald is more than a story about a mans love for a women, but rather a mans will to achieve greatness as he perceived. Jay Gatsby was a man driven by money and power. He was a man with a vision, a vision to succeed in life. As a child, Jay Gatsby grew up on a farm. He saw his parents as nothing but lethargic farmers. Gatsby knew exactly what he didn’t want to be and that was like his parents. They were people who were content with who they were. Gatsby, on the other hand, was the exact opposite. He wanted to move on. Jay Gatsby wanted to be someone special, someone with prestige and someone definitely with money. Gatsby developed a self improvement plan to help him flourish as a young man. His plan detailed dumbbell exercises, studying electricity, practicing elocution and studying needed inventions. Even his parents knew he was driven. His father said: "Jimmy was bound to get ahead.. He always had some resolve like this or something. Do you notice what he’s got about improving his mind? He was always great for that" (182). The structured drive let Gatsby prevail in his endeavors. However, there are some things people just can’t get away from. James Gatsby desperately wanted to achieve success in life. However, it is difficult to flourish with a background like Gatsby’s. So to escape his past, he changed his name at the age of 17 from James Gats to Jay Gatsby. Nonetheless, changing his name only did so much for him. Gatsby ended up living a life of lies because of his hidden identity. Nobody really knew Gatsby. So in the absence of peoples knowledge, they conjured up rumors. "One time he killed a man who found out he was a nephew of von Hindenburg and second to the devil"(65). These were just some of the rumors about Gatsby. Some believed he was a German spy, while others thought he was a war hero. These were things he had to go through to reach his ultimate goal in life, which was to succeed. After he left the farm, Gatsby went to work for a man named Dan Cody. Cody was a stable father figure for Gatsby. He looked up to Dan and saw what he really wanted to be. "That’s Dan Cody, old sport.

Has Slavery Changed since Ancient Times? :: Slavery Essays

Has Slavery Changed since Ancient Times? Slavery has always been a large issue and possibly always will. The issues of today are often negative but did you know that back in ancient Roman times they were all for it? Well they were! The question that will be answered in this assessment is "In what ways, if any, has slavery changed from ancient to modern times?" I believe that slavery has changed very much from the past. Not that there may be more or less of it, but that it may be harsher and have worse conditions. In the ancient times slavery was a common and normal thing. In 70 A.D it was estimated that there were slaves in Rome. There were no troubles or controversies over it. Slavery was widespread and most families owned at least one slave. Today there is only one real way to become a slave but in Roman Times (rise of Rome) there were three. 1=Slavery due to crime committed. 2=Not being a Roman citizen. 3=Taken prisoner by Romans. An example is war. Some of these may seem unfair but it was the Romans belief in their superiority. There were many types of slaves that were good at different types of jobs. Often, rich families had so many slaves that they didn't really have to do any work around the house at all! There were other types of slaves apart from the above. These were Statuliberi = Slaves freed by their master's will. Servi sub unsufructu manumissi =Slaves made free by will remaining as slaves. Bona fide servientes = Freemen acting as slave to master Auctorati = Free men who were gladiators, under a contract to their gladiatorial master. Redempti = Freemen captured in war and ransomed back to non-relatives. They worked until they paid off their debt. Coloni adscripti glebae = Free persons who were tenant farmers. These slaves were not treated as a person but as an impersonal asset although they did have their rights. These were dismal rights but they were important for the slaves well-being. The rights were as follows: the slave was allowed his personal items (like money etc.), he could not be killed without a good reason. Masters had rights too of course. They could treat a slave anyway they wanted to. They could be abusive, friendly or do anything they wanted to the slave. They could defend themselves against slaves and could kill him/her if the master provided the courts with a good reason.

Environmental Economics & climatic change Essay

Many approaches to green house emissions are currently being examined in the United States. In fact members of the 110th Congress (2007-2008) are actually making legislations pertaining to global changes faster than has even been experienced before having made over 235 bills, resolutions and changes by July, 2008. One such proposal is the cap-and-trade system (Paltsev et al. 4). The cap-and-trade is a piece of legislation meant to identify the greenhouse-gas-emitting bodies it incorporates. It refers to those organizations which introduces caps on the emissions they are responsible for and allows trading in the emission allowances which arise therein (Obama & Biden, New Energy for America). They basically stipulate a set of accounting periods allocating allowed emissions for all the periods (Paltsev et al. 4). Cap-and-Trade Legislation; SO2 Program The permit trading programs offer pollution permits to organizations which reduce their pollution discharge lower than the target benchmarks. They are then allowed to either trade them or keep them for use in future (Ludwig 1). Following the Clean Air Amendments of 1990 the U. S put in place the Acid Rain Program to gain a reduction in sulfur dioxide (SO2) and nitrogen oxide (NOx), the main contributors of acid rain (Ludwig 1). The second program was the Hot-spots and acid rain program which basically involves regulatory tiering; embracing more than one regulatory regime at one specific time with the intention of exercising some control on the way permits are made use of (Obama & Biden, New Energy for America). The goal of the acid rain program is to reduce SO2 emissions by 50%; a task meant to be accomplished through two stages mandating all organizations to reduce their SO2 emissions (Ludwig 3). The Opt-in program established by the Congress according to section 410 of the Clean Air Act Amendments of the year 1990 was designed with the intention of drawing the SO2 sources with reduced marginal costs of compliance (Ludwig 3). It is important to note however that the permit trading programs are not effectively contributing towards reducing increased emissions. Indeed the acid rain program of the United States has had less and unlikely effects on pollution hot-spots (Ludwig 10). This is quite unfortunate given the main energy challenges facing the U. S, which are foreign oil dependence and global changes in the climate (Obama & Biden, New Energy for America). The safeguard the acid rain program makes use of is one of the reasons permit net flows have such a low effect on reducing emission. Alternative Method of Pollution Control It is worth appreciating that carbon trading at the markets was a positive step be it at the global, European or national fronts (NCEP, Ending the Energy Stalemate: A Bipartisan Strategy to Meet America’s Energy Challenges). It was in deed a challenge not only to the government but also to the private sector (Obama & Biden, New Energy for America). If the war against carbon emissions is to be worn, a global regulatory framework would be needed (Watson et al 1). This would call for British Government and the World Bank to embrace the same views. This means that the cap-and-trade legislations can no longer offer the best solution to the problem. What is needed is a different approach, an alternative way of reducing carbon emissions. In light of the climatic changes being experienced, carbon emissions should be reduced by all chances (Obama & Biden, New Energy for America). This calls for a new trading strategy; an approach which is more inclusive likely to involve all ventures emitting carbon such as aircrafts and ships (Watson et al 1). In the private sector this would call for a wider long-term market approach, voluntary in nature working to achieve public and private interests. The Kyoto Protocol should be strengthened coupled with better implementation of the Clean Development Mechanism (CDM) (Watson et al 1). Indications of progress are beginning to be seen with incentives for reducing emissions, development of alternative technologies as well as investments attraction (Watson et al 2). There is also the need for better liaison with the UN system more so in helping poor countries with their emission problems (NCEP, Ending the Energy Stalemate: A Bipartisan Strategy to Meet America’s Energy Challenges). This therefore means that carbon taxation is definitely not an alternative solution the emission problems. There is need to invest in fuel-efficient machinery, support domestic energy supply, as well as diversifying the nations’ sources of energy (Obama & Biden, New Energy for America). Organizations also need to commit themselves to the course of lowering their energy consumption (Watson et al 2). The Legislation I would Support As an undergraduate in ApEc 3611, I would support the second alternative because it more inclusive, realistic and possibly a better solution since it involves many stakeholders (Watson et al 2). What I imply here is that a new alternative to America’s and indeed the world’s energy problem is an idea whose time has come (NCEP, Ending the Energy Stalemate: A Bipartisan Strategy to Meet America’s Energy Challenges). Energy is a real challenge facing the world and for America, there is even greater need to address the issue because of foreign oil dependence (Obama & Biden, New Energy for America). Therefore I support the new alternatives to reducing carbon emissions. The private sector needs to embrace a wider long-term market perspective but within the confines of both the public and the private interests (Watson et al 2). This new perspective calls for more research into the areas of innovative technology as well as new investments. Indeed one of the mid-to-long term proposals to the energy crisis in America is to make investments towards the secure energy future of the nation alongside creating more than 5 million jobs all with the intention of lowering foreign oil dependence (Obama & Biden, New Energy for America). Such efforts will greatly reduce carbon emissions besides contributing towards the reduction of the country’s dependence on foreign oil (NCEP, Ending the Energy Stalemate: A Bipartisan Strategy to Meet America’s Energy Challenges). There is need to strengthen the Kyoto Protocol and the implementation of more stringent governance and accountability systems (Watson et al 2). The Emissions Trading System (ETS) needs to be reviewed (Hertel, Global Trade Analysis: Modeling and Applications). This is because for it to be successful, it needs to put caps on emissions. This will create both markets and prices for carbon emission permits (Watson et al 2). I therefore fully support these new alternatives since they offer a more proactive approach to the nation’s energy problems. Cost Benefit Analysis The lake in question is private property if the home owner has the property rights to it. This would mean that as a private good it can only be used by another party if it is paid for. It is the lake owner who would decide whether or not another party uses the lake. For this to happen, the total benefits accrued from the use of the lake will have to supersede the costs of using the same lake thus a Pareto improvement (Oka 18). The lake owner will have to carry out a cost-benefit analysis before he can allow fishing in the lake. This is an evaluation tool to determine if the use of scarce resources will generate efficiency (Fuguitt & Wilcox 2). Efficiency is in relation to the lake will be the benefit of peace and quiet at $2,000 per season. It means the benefit of allowing Walleye Wally to use the lake will be $ 2,000. With $ 2,500 he can meet the $2,000 and secure the fishing deal meaning that there will be fishing in the lake. However, with only $1,200 per season, he cannot meet the cost of foregoing the peace and quiet thus there will be no fishing. Assume Walleye Wally had the property rights and the benefits of peace and quiet to the home owner remain unchanged at $2,000. With $2,500 there would be fishing in the lake. The lake owner cannot however pay Walleye Wally not to fish since the cost of paying Walleye would supersede the benefit of peace and quiet, hence there will be no Pareto improvement. If Walleye got $1,200 per season there cannot be fishing in the lake since the benefit of the fishing will be less than the cost and hence no Pareto improvement. This transaction cannot be termed as efficient since one party will suffer loss in the transaction. The principle that by which the concept of efficiency is applied is here is the cost benefit analysis (Oka 19). Conclusion There are factors that would hinder the cost-benefit analysis. For public goods, it is difficult to measure the efficiency concept and the Pareto improvement concept is lost. The consideration of potential value that would be attached to sustainability would make it difficult to make an accurate cost-benefit analysis (Oka 26). In conclusion, cost-benefit is an economic tool used for gauging the efficiency of a transaction in the market economy (Oka 17). With regards to CO2 emissions, there is need for a new direction which will require a more centralized regime; a continual and joint effort between the government, businesses and the people (Obama & Biden, New Energy for America).
