The Effect of Organized Sport on Children

The Effect of Organized Sport on Children Free Online Research Papers It is obvious that the American society is obsessed with sports. All one needs to do to see this obsession is turn on the television and watch one of the dozens of twenty -four hour sports stations and commercials dedicated to sports. Still not convinced, then hop into your car and take a drive across any suburban American town and look at the parks and playing fields. They are full of adult and children athletes playing for leisure and competition. We, as adults, have made athletics into a billion dollar industry as spectators and participants. Our need for sports fuels our pride and self worth as Americans. However, organized youth sports in the U.S. are still a relatively new phenomenon. Prior to 1954, most organized sports in this country took place through social agencies such as the YMCA, Boys and Girls Club, Boy Scouts and Girl Scouts, etc. (Seefelt Ewing, 1997). Since this time, the benefits provided by these activities have developed into private youth sports organizatio ns primarily run by volunteering adults. Does our obsession have a purpose? Do organized sports play a positive role in the lives of our children? At first thought, any red blooded American would say absolutely. But can we explain why and in what way organized sports benefit our children? Parents and coaches have alluded to the idea that sports are great for kids for decades, but when this comment is made it seems to be accepted without any question. In the following text we will discuss specific benefits from participation in organized sports including the physical, psychological, and academic impact of sport on children. We will also look at the research to see the concrete proof that organized sports play a vital role in the development of the youth of this country. Physical The most alarming issue facing the health of our country and specifically our children is the epidemic of childhood obesity. The infrastructure of our nation’s health care system will be tested as we see the first wave of obese children reach adulthood and deal with the related health issues. The scary facts are that the lifestyle and diet we promote is trickling down to the children of this country. Health issues that are linked to adult obesity are now becoming more and more common in children and teens. For example, type II diabetes was once considered adult on-set diabetes, but today the cases of children with type II diabetes is raising at an alarming rate. The estimated yearly cost of obesity in this country is estimated at around 61 billion dollars. With these issues facing the children of this country we need a cure right? Well a portion of that cure is located in organized sports. The solution is simple to stopping the trend of childhood obesity; eat less and be mo re active. Today children in this country are far less active than prior generations. Through childhood activity, we are not only saving our children from a life of obesity as adults but we are also potentially saving this country billions of dollars in missed days of work, dollars spent on health care, and rising disability rates. (Healthierchildren.org). In 1997, the CDC stated within its â€Å"Guidelines for Schools and Communities for Promoting Lifelong Physical Activity† that youth sports can promote positive behavior that can last a lifetime (Seefelt Ewing, 1997). Much debate has been discussed in the general public about the frequency and duration it takes for a child athlete to receive benefits from physical activity. Boys and girls who participate in just two 50 minute training sessions per week improved their aerobic capacity by 15% in just six months (Eppright, Sanfacon, Beck Bradley, 1996). How young is too young for involvement in organized sports? Children under the age of 5 are more than likely to receive from organized sports the simplest of benefits. For example, children at this age seem to enjoy the advancement in motor skills and interaction and not the competitive aspect of the activity (Eppright, Sanfacon, Beck Bradley, 1996). A study in Singapore showed that even preschoolers could benefit from involvement in organized sports. This study showed that preschoolers who participated in organized sports where stronger physically, socially, and emotionally developed than peers who were not evolved in organized sports at the preschool level (Nonis, 2004). As with adults over training is a serious issue. A 1980 study detailed the risks of over training with child athletes. There is points in training were growth actually may be retarded (McKeag, 1980). This extreme should not scare parents from allowing there children to participate in a appropriate level of physica l activity. Academics We live in a competitive world and as a culture it is our duty to prepare children for the competition. The benefits of organized sports reach farther than the playing fields and hardwood floors of our schools. Organized sport has the potential to also help our children in the realm of academia. Sports help us to prepare for a life filled with stiff competition. Organized athletics teach children to respect authority and to develop time management skills outside the classroom; to be able to balance the responsibilities of being a student and an athlete. The typical stereo-type of the â€Å"dumb athlete† couldn’t be any farther from the actual truth. Current research actually points to a relationship between organized athletics and higher academics. The lessons learned outside the classroom transfer directly into relationships with teachers and peers in an educational environment. The research points to a direct correlation between organized sports and higher development rates in academics. Athletics teach our children to master skills and to focus on the development of virtue over the outcome (Durrant, 2007)). This is a concept that parents and coaches since the dawn of sports have stressed. Organized sports teach life lessons of discipline, hard work, dedication, and how to push through adversity. But the stereotype of the â€Å"dumb jock† has also haunted organized sport as well. The truth is that students who participate in extra curricular activities including organized sports tend to be more academically equipped (Fredricks Eccles, 2006). It must be noted that students who participate in multiple extracurricular activities including those outside of organized sport seem to benefit the most academically. Psychological The average person knows that there is a positive feeling of self that comes from physical activity and exercise. From a physiological stand point we could say that this is caused by the body producing natural endorphins that just make us feel good for a short period of time following exercise. But the truth is through organized sport we build a sense of self worth, and accomplishment not present in exercise and physical activity alone. These positive feelings we feel following participation in organized sport are the direct result of putting hard work in and seeing the outcome for the whole group not just the individual. The truth is that sports give children an opportunity to develop self concept and how to express themselves within a group. It seems that this is a natural need that even children who do not participate in organized sports have. For example, children in early elementary school are seen looking for situations to act out their competitive nature; competition becomes an independent social motive. Organized sports give these children an outlet for this natural behavior (Eppright, Sanfacon, Beck Bradely, 1996) As health professionals, it is our job to promote behavior that will increase quality of life and educate Americans on the risk taken in certain behaviors, yet in this country today our children are living lives of risk. Our children are putting themselves at risk for sexually transmitted diseases, substance abuse, adult obesity, diabetes, cancer, heart disease, etc. Extracurricular activities including organized sports have a direct impact on decreasing risky behavior by children. This can mainly be explained due to the type of peers a child associates with on a regular basis. If a child participates in extracurricular activities his or her choice of friends is likely to be from the pool of children that participate in the given extracurricular activity. Peers who are involved in extracurricular activities tend to be more academically conscience and less likely to live lifestyles promoting risky behavior (Fredricks Eccles, 2006). If a child is surrounding them selves with responsi ble peers risky behavior is likely being decreased. In American society today it seems antisocial behavior is accepted, we claim that it’s just a phase or that it’s alright to just be who we are. While both of these may be true, a healthy person is a pro-social person who can function in main stream society. So what role can organized sport play in creating positive pro-social behaviors in children? Children who have been involved in organized sport tend to be more pro-social than their counterparts who have not been exposed to organized sport at an early age. Sports have been used with some success with improving adults and children with antisocial issues, but no clear evidence has shown sports as an effective treatment for antisocial behavior issues (Duncan, 2004). Organized sports may not have a place in treatment of children with antisocial issues but it is clear that children who have been exposed to sports at an early age are less likely to have antisocial disorders. Organized sports participation has been proven to lower scores in the areas of externalizing problems, social problems, aggression problems, and delinquency problems (Donaldson Ronan, 2006). The number one psychological issue in the life of a child or young adult is the idea of self worth or self concept. The easiest way to define self concept is how do I feel about myself? What kind of self worth do I have? Various researchers have pointed to self concept as the variable with the most potential to reflect the most positive psychological gains (Sonstroem Morgan, 1988). Researchers have found a positive relationship between organized or formal sports and a positive concept of self (Donaldson Ronan, 2006). The strength of self concept is built through the knowledge that I, as a person on my own, can finish what I start. I, as a person, can put my mind to a given task and perform that task with the skill I have learned through hard work. And most of all, I can contribute to the group giving us overall success. The large focus of research in the health and sport community has focused on the benefits of organized sport, but can children receive the same social benefits from relatively unorganized sports activities? The answer to this question seems to be that children do not benefit from the same life skills that come from organized sports. Organized sports do create an environment where we learn to exist within the team concept. The world of organized sport appeals to young people who are drawn to the team concept and have a positive view of authority and the group concept. However, the earlier children are involved in organized athletics the more likely they are to be attracted to these sports as a adolescent (Donaldson Ronon, 2007). Many have witnessed the out of control parent at a little league game or a child who participates in too many activities and gives up a sport at a later age. These are examples of the negative impact of youth sports. The negative impact of youth sports is a real and valid concern. The psychological benefits of youth sports are just as great for the child who grows up to have nothing to do with competitive athletics (McKeag, 1980). Conclusion The proof is in the research, organized sports provide positive benefits. Physically, children who participate in organized sport are less likely to develop asthma and diabetes as adults. Academically, children who participate in organized sports are more likely to excel in the classroom. Socially, children who participate in organized sport are less likely to suffer from depression and less likely to participate in antisocial high risk behavior. With all the positives involved, why do we see so many states and individual school districts cutting funds and opportunities for children to participate in organized childhood sports? It is vital that we fight to not only keep childhood sports a priority in our primary schools but also expand those programs. As parents we must take it on ourselves to give our children every chance to benefit from organized youth sports, even if it means taking time out of our own busy schedules to volunteer. As Americans we cannot afford to see a day when o rganized sports are limited to only those families who can afford to pay for their children to participate in them. In order for organized sport to become a priority in this country, we as health professionals must educate the public on the positives and how they translate to the long term financial and social benefits for our country.

Illegal Immigration - For illegal immigration for America Research Paper

Illegal Immigration - For illegal immigration for America - Research Paper Example It also includes the existing laws being implemented to combat this long-term issue that has conquered America by storm. It will also document the reasons as to why the US immigration policies failed as evidenced by the increasing number of illegal immigrants from all over the world. The role of government is given an emphasis to come- up with domestic policies to ensure that security and anti-terrorism concerns of the country are dealt with by law. Lastly, it will also provide the worldwide effect of immigration in the US and the participation of the other nations on how to prevent their citizens from entering the US without legal documentation. Keywords: illegal immigration, immigration laws, amnesty, legalization, illegal immigrants. ILLEGAL IMMIGRATION IN AMERICA Since time immemorial America has been considered the land of â€Å"milk and honey† for millions of people from all across the world. Most of the citizens from poor countries aim to reach America as their end dest ination thinking that this is the place where there is more than enough for everything. It has been perceived as the land of abundance, wealth and endless opportunities. The ultimate goal of the illegal immigrants is to enter US and land a job which will earn them a substantial income to support their families in their country of origin. However, at present time, we all know that America has been experiencing economic recession and even its countrymen were not spared of this crisis, as many became unemployed, homeless and suffered financial distress. Dubbed as the â€Å"nation of nations†, Lemay (2009, p. xv) has reported that the United States has absorbed immigrants from 170 countries across the globe. It has been the home of almost 70 million legal immigrants and experienced the influx of an estimated 11 million of illegal immigrants. The unauthorized flow of illegal immigrants entering the America is caused by inefficiencies of the immigration system of the US government to enact stricter laws and policies to address the current problems. History Ngai (2007, p.2) has reported that as early as 1920’s, the unauthorized entry has become the most common form of illegal immigration which has been condemned by both the state and the society. These unauthorized immigrants may either be welcome or unwelcomed by the US. They became in demand by the economic sector as their labor is cheap and replaceable. In the middle decades of the 20th century, they were only billeted in the western and southwestern agriculture. But at present, illegal immigrants have evolved and can be found in almost every region in the United States. Based on the records, the United States documented the number of immigrants who earned the status of authorized immigrants. â€Å"An approximate of 70 million of them forms part of the legal immigrants, but as history would tell us, the flow of unauthorized entrants likewise increased. According to LeMay (2007 p.1), the heavy traffi c of these illegal immigrants commenced after 1970, and the massive volume was recorded at present time. Today, there is an estimate of 10.5 to 11 million illegal immigrants living in the US. The Evolution of US Immigration Laws In the study made by Kenney (2009, pp. 21-23), she highlighted the significant immigration laws: The Immigration and International Act of 1965 was the law which set the limit on the immigrants coming from the Western Hemisphere, including Mexico. It set a limit of 20,000

Peter roberts watches expanding in HONG KONG - Essay Example PESTEL analysis (Porter, 1980) focuses on the external forces that play a key in role in a firm’s ability to produce and sell. The political analysis relates to the political context of a country and governments often use them to influence the business operations. According to (Porter, 1980), these factors include trading policy; international relations and taxation policy just to mention a few. Hong Kong is relative a stable and thus offers an excellent environment for international investors to conduct business. However, the imposition of 30% tax on international companies while letting local companies free could pose challenges to Peter Roberts watches in terms of competition (HKTDC Research, 2015). Porter (1985) posits that economic factors have a significant effect on business and, in particular, the national economy where the business is located. The economic factors influence business largely in terms of income, interest rates, and general demand. Kotler et al. (2013) argues that high-interest rates discourage investment whereas high inflation affects employee wages. Hong Kong is a rising, stable economy with low inflation rates; consequently, this will be more appealing to Peter Roberts Watches to conduct business. Porter (1985) describes social factors as encompassing factors such as population growth rates, social attitudes, and social demographics among others. The significance of these factors is in their ability to affect the demand for a firm’s goods. Hong Kong’s population has a significantly large proportion of its population composed of the Y-generation (Lenway & Murtha, 1994). This generation is fashion conscious and has a high affinity for trendy products. Peter Roberts Watches firm’s ability to produce a variety of watches including fashion will ultimately appeal to this population hence market (Peter Roberts, 2015). Technological factors

How Continuous Quality Improvement Can Address Medical Errors

How Continuous Quality Improvement Can Address Medical Errors This paper will cover medical errors and how Continuous Quality Improvement can address them. Health care managers have addressed the issue of medical errors for many years. Medical errors can be caused by lack or communication and leadership. Quality improvement in the health care environment is a hot topic and managers are researching ways in which they can increase the quality of care that a patient receives. The quality of care that a patient receives can be the determining factor as to whether they live or die. It is critical that managers develop policies and implement control measure to control the rise of medical errors. Attention to medical errors escalated over five years ago with the release of a study from the Institute of Medicine (IOM), which found that between 44,000 and 98,000 Americans die each year in U.S. hospitals due to preventable medical errors (Kaiseredu, 2010). Hospital errors rank between the fifth and eighth leading cause of death, killing more Americans than breast cancer, traffic accidents or AIDS. Serious medication errors occur in the cases of five to 10 percent of patients admitted to hospitals. These numbers may understate the problem because they do not include preventable deaths due to medical treatments outside of hospitals (kaiseredu, 2010). Health care managers, along with the Food and Drug Administration, have study the medical error reports to determine the cause of errors. Medical errors are one of the leading causes as to why health care has declined. To improve healthcare managers must determine how to decrease the mortality rates. Managers can determine this by studying and analyzing medical reports. These reports provided managers with detailed information on what procedure was being conducted or what medication the patient was administered. In a study by the FDA that evaluated reports of fatal medication errors from 1993 to 1998, the most common error involving medications was related to administration of an improper dose of medicine, accounting for 41% of fatal medication errors. Giving the wrong drug and using the wrong route of administration each accounted for 16% of the errors. Almost half of the fatal medication errors occurred in people over the age of 60. Older people may be at greatest risk for medicati on errors because they often take multiple prescription medications (Stoppler Marks, 2010). History has shown that many surveys and research studies have been conducted, so that providers can learn where and why mistakes are being made. Once providers have a clear understanding, they can implement control measure to insure these mistakes do not occur. National Patient Safety Foundation Survey: The National Patient Safety Foundation (NPSF) commissioned a phone survey in 1997 to review patient opinions about medical mistakes. The findings showed that 42% of people believed they had personally experienced a medical mistake. In these cases, the error affected them personally (33%), a relative (48%), or a friend (19%) (Wrongdiagnosis, 2010). Patients that were given the survey have experienced the following medical errors: Misdiagnosis (40%), Medication error (28%), Medical procedure error (22%), Administrative error (4%), Communication error (2%), Incorrect laboratory results (2%), Equipment malfunction (1%), and Other error (7%). Patient safety should be the number one concern for health care organizations. Health care managers are held accountable for ensuring that patients are provided with quality care. They are also accountable for the patients that are injured or die due to a providerà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s medical error. The health care industries along with scientific researchers have developed tools in which the quality of care can be measured. Organizations can use these tools to determine if effective care is being provided. Once they have determined the level of care they are providing, they can educate providers on what they are doing both wrong and right. The most common method used to determine the quality of care, is through the use of surveys. Health care organizations can provide staff and patients with surveys to determine what areas the organization can improve and sustain. These surveys will not be provided to every patient the provider has treated but only a selected few will be surveyed. Quality measurement in the healthcare industry requires a large amount of resources and funding. Researchers will most likely use methods that have worked before and have provide them with data; they could use to enhance the level of care the organization is providing. Healthcare researchers are constantly trying to find ways in which the completely eliminate medical errors. Due to the continuous cycle of experienced providers leaving and new providers being hired, medical errors in many cases will never be eliminated. Health care organizations can however implement the necessary control measures to ensure that patients are not misdiagnosed or the wrong limb is not amputated (Cohen, 2007). Healthcare organizations can decrease medical errors by establishing a continuous quality improvement plan that calls for the development of a multidisciplinary team to research and investigate the causes of medical errors. The Department of Veteran Affairs uses a CQI model developed by the Joint Commission to reduce the number or medical mistakes made by providers. Joint Commissions surveys all the Veteran Affairs Medical centers to see whether their staff is following the medical policies and regulations in providing quality care. Joint Commission has also established policies regarding how health care organizations will report and handle sentinel events. A sentinel event is an unexpected occurrence involving death or serious physical or psychological injury, or the risk thereof. Serious injury specifically includes loss of limb or function. The phrase, or the risk thereof includes any process variation for which a recurrence would carry a significant chance of a serious adverse outcome. Such events are called sentinel because they signal the need for immediate investigation and response (Jointcommission, 2010). In conclusion medical errors can occur at anytime while a patient is receiving care. It is important that health care providers communicate and provide education to their staff on reducing the number of medical errors, the facility has encountered. Medical errors can lead to the organization being sued by the patient or the patient family member. Law suites can be devastating for any organization to go through and can reduce the amount of funds that have been allotted to providing quality care. Therefore it is important that medical errors are reduced and even eliminated.

Financing the Purchase of a Website - The Small Business Administration (SBA) :: Sell Websites Buy Websites

Financing the Purchase of a Website - The Small Business Administration (SBA) Reprinted with permission of VotanWeb.com One of the Small Business Administration's primary objectives is to help small businesses obtain financing. Although the SBA itself does not make direct loans, it has set up a number of loan programs to assist small businesses. In connection with most of these programs, the SBA provides guarantees to the private sector lenders who actually make the loans. With this guaranty in place, these lenders will generally make loans for the purchase of websites that they would not otherwise make. The discussion below focuses on those programs that are most commonly used by buyers in connection with financing the purchase of a website. Section 7(a) Program The Section 7(a) Loan Guaranty Program is one of the SBA's most important and widely used lending programs. Loans may be used for a wide variety of business purposes, including the purchase of websites and most other types of assets. Although in most cases, there is no limit on the size of the loan which can be requested from the lender, there is a limit on the amount of the loan that the SBA will guaranty. Generally the SBA will guaranty up to $1,000,000 and 75% (85% for loans under $150,000) of the loan. Thus, a $1,333,333 loan would be the largest fully guaranteed SBA loan under the Section 7(a) program. Eligibility for this type of loan guaranty is dependent on a number of factors. The website must be operated for profit, do business in the , and have a reasonable amount of equity invested by the owner. Note that all owners of 20% or more of the website must personally guaranty the loan. The size of the website must also be below certain size limits established by the SBA. These size limits vary by industry. Additional considerations include the website 's cash flow, and the owner's character, management capability, and equity contribution. Other details include: Loan Maturities - Term is based on the ability to repay, the loan purpose, and the useful life of the website. The maximum maturities are (i) the shorter of 25 years or the useful life for most hard assets and (ii) 7 years for working capital. Principal Repayments - Loan principal is structured to amortize over the period of the loan. Thus there is no "balloon" balance owing on the loan's maturity date. Interest Rates - Interest rates can be either fixed or floating, and are negotiated between the borrower and the lender.

Chapter # 1 Introduction 1. 1: Basic Introduction Radio Controlled (RC) plane is basically a smaller prototype of an actual aircraft and its dynamics are relatively difficult to understand. For RC Plane there is 3-degree of freedom. Important parameters are: roll, pitch and yaw. To achieve control of these parameters, there are three control surfaces ailerons, elevators and rudder. 1. : Transmitter/Receiver †¢ A Transmitter is an electronic device that gener ates and amplifies a carrier wave, modulates it with a meaningful signal derived from speech or other sources, and radiates the resulting signal from an antenna. The transmitter used for project has 6 channels and is programmable for both airplanes and helicopters. It has a 3-way flap switch, aileron and elevator dual rate switches, rudder mix switch, gear and aux2 switch. A preset memory makes it possible to set up several different models on the same radio. †¢ A  Receiver  converts signals from a radio  antenna  to a usable form.It uses  electronic filters  to separate a wanted  radio frequency  signal from all other signals, the  electronic amplifier  increases the level suitable for further processing, and finally recovers the desired information through  demodulation  and  decoding. Information carried on a radio signal may represent sound, images or data. We are using a 6 channel tiny 4 grams receiver with signal path diversity. 1. 3: Microcontro ller We will be using Arduino AT-Mega 328 Microcontroller and it has a dedicated PWM pin. It has built in ADC therefore no external ADC is required and it is very much faster than Atmel Microcontrollers . 4: Digital Gyroscope How Gyroscopes Work: Gyroscope can balance on almost on any surface with single contact: It can be a finger or even a string. They can resist motion about the spin axis in very odd ways; but the most interesting effect is that gravity-defying part which is called  Precession. We will be using Eclectic Gyroscope in our RC Plane to provide it with stable Flight. We are using Gyro ITG 3200. Chapter # 2 Literature Review 2. 1: History The earliest examples of electronically guided model aircraft were hydrogen-filled model  airships  of the late 19th century.They were flown as a music hall act around theater auditoriums using a basic form of spark-emitted radio signal. In 1920s, the  Royal Aircraft Establishment  of Britain built and tested the Larynx, a  monoplane  with a 100-mile (160  km) range powered by a Lynx engine. It was not until the 1930s that the British came up with the Queen Bee, a modified  de Havilland Tiger Moth, and similar target aircraft. Radio control technology has been in use since 1893, when Nikola Tesla created a boat that was controlled by transmitted radio waves. In 1917, the first radio controlled airplane was successful.During World War II, Germany tried a variety of weapons that were operated by radio control. Radio controlled model airplanes have evolved over the years and seen improvements since that first flight in 1917.

The less force needed to move the rudder the less stress is put on the servo during flight. Alternatively cut them off and use clear packing tape to re-attach them, one slice on each side.

[pic] Aileron For maximum throw, the aileron wing servo has to be swapped around vertically. The servo head should be pointing toward the back instead of the leading wing edge 4. Mechanical Analysis All dimensions of the Plane are From National Advisory Committee for Aeronautics  (NACA) , we selected the NACA series of 0015 as it was cheaper to fabricate. The Analysis of the Aerofoil was performed on Gambit & Fluent as these software are used for fluid analysis.We calculated the Coefficient of Drag & Lift using these software to determine whether the plane will fly or not. The coordinates of the NACA series 0015 was taken from the NACA site. Theoretical Calculations †¢ Length of Aerofoil (chord)= 19 cm †¢ Max Thickness of Aerofoil=2. 85 cm (2. 85/19)*100= 15 We Know that our Aerofoil is Symm etrical, therefore the The NACA Series number of our Foil is 0015 †¢ The NACA 0015 airfoil is symmetrical, the 00 indicating that it has no camber. The 15 indicates that the airfoil has a 15% thickness to chord length ratio: it is 15% as thick as it is long.NACA 0015 1. 000000, 0. 001580 0. 950000, 0. 010080 0. 900000, 0. 018100 0. 800000, 0. 032790 0. 700000, 0. 045800 0. 600000, 0. 057040 0. 500000, 0. 066170 0. 400000, 0. 072540 0. 300000, 0. 075020 0. 250000, 0. 074270 0. 200000, 0. 071720 0. 150000, 0. 066820 0. 100000, 0. 058530 0. 075000, 0. 052500 0. 050000, 0. 044430 0. 025000, 0. 032680 0. 012500, 0. 023670 0. 000000, 0. 000000 0. 012500, -0. 023670 0. 025000, -0. 032680 0. 050000, -0. 044430 0. 075000, -0. 052500 0. 100000, -0. 058530 0. 150000, -0. 066820 0. 200000, -0. 071720 . 250000, -0. 074270 0. 300000, -0. 075020 0. 400000, -0. 072540 0. 500000, -0. 066170 0. 600000, -0. 057040 0. 700000, -0. 045800 0. 800000, -0. 032790 0. 900000, -0. 018100 0. 950000, -0. 01 0080 1. 000000, -0. 001580 Chapter # 4 References 6. 1: Reference Books 6. 2: References Web-Sites file:///G:/GBx%20Brushless%20Motor%20Calculator. htm http://www. futaba-rc. com/ http://www. mathworks. com/products/sl-design-optimization/demos. html? file=/products/demos/shipping/sldo/spe_servomotor. html http://www. futaba-rc. com/servos/brushless. html www.

Sociology- Nature Versus Nurture - 1816 Words

Nature versus Nurture The roles of nature (what we genetically inherit) and or nurture (what we learn) in making us what we are have long been argued. The idea that humans are determined by these two influences dates back to the ancient Greek philosopher Protagorus who in the fifth century BC compared physics (nature) and nomos (tradition). It is however difficult to unravel the separate influences of nature and nurture. If the children of musically talented parents are themselves musically talent, is it because of genetic inheritance (nature) or because of a musical environment at home where they grow up(nurture)? The nature versus nurture debate concentrates on the question of how far our behavior is determined by nature at birth†¦show more content†¦Ã¢â‚¬ ¢ Both drove a blue Chevrolet. †¢ Both built white benches round the trunk of a tree in their gardens. †¢ Both had a habit of biting their fingernails. †¢ Both were chain smokers of same brand of cigarettes †¢ Their tem peraments, voice patterns and nervous habits were also similar. Thus the case of Jim Twins might lead us towards the idea that nature determines our human behavior. Sociobiology (the systematic study of the biological basis of all social behavior) was developed by E.O. Wilson in 1980 s. According to sociobiology’s human behavior is determined naturally just like animal behavior. According to sociobiologist Steven Gavlin and Alice Schlegel (1980) individuals act in order to maximize their genes in future generations. Thus the tendency of man to have sexual relationship with beautiful women is to maximize his genes. Similarly behavior of both men and women is thus guided by genetic factors. These above mentioned evidences shows that human behavior is determined by nature or genetic influences. Our race (color of the skin and other bodily features (sex, certain diseases, flood groups, are no doubt inherited. Human beings are directly influenced by nature.
