Essay on Social and Evolutionary Psychology - 1041 Words

Social and Evolutionary Psychology In an attempt to define civilized man’s relationship to the jungle and primitive societies, one must first consider the theories of social psychologists who have offered interpretations of modern man’s reactions upon insertion into a primitive setting. The main contrast in human states that arises from this argument is the concept of civilization versus savagery. Much is uncovered about the path man tends to take when confronted with these two options when studying the research as to what arises from man’s savage tendencies when the restraints of society no longer tame human primal instincts. One such field that explores the instinctual nature of the human psyche is†¦show more content†¦This deduction might suggest that upon reinsertion into a primal environment, humans would be even more prone to resorting back to their â€Å"instincts† as uncivilized beings. Thus, we learn from theories in Evolutionary Psychology that human â€Å"instincts† are the underlying driving forces to human action that are more potent than the restraints imposed upon man by society, and even more prevalent in â€Å"human nature† than in the daily conduct of animals apart from humans. Another field in which the distinction between civilized and primitive man is discussed is that of Social Psychology. Much emphasis is placed upon the effects of societal laws on the governance of human action. A major psychologist in this domain was William McDougall(1871-1938). In his work, An Introduction to Social Psychology, McDougall exposes various theories on the distinct aspects of civilized and primitive human tendencies: â€Å"We may accept Bagehot’s dictum that it is difficult to exaggerate the difference between civilised and primitive men (i.e., really primitive men, not the savages of the present time) in respect to their innate law-abidingness, and while we may accept also his view that the strict enforcement of law played a great part in producing thisShow MoreRelatedSocial Psychology And Evolutionary Psychology793 Words   |  4 PagesRecently a start-up social marketing Silicon Valley executive was quoted as saying If you are comfortable when you launch your site you waited too late.

Continuing with love and nurturing, advocates can see that children of gay or lesbian couples actually grow up with the ability to be more psychologically empowered.

In addition, they have a tendency to show their children the same if not more affection than heterosexual. The reason for more affection is in relation to the procedure the parents went through to adopt the child. The adoption processes for homosexuals are so hard that some move to different states just to get their case taking for consideration.

Organisational Change and Culture-Free-Samples-Myassignmenthelp.com

Question: Discuss about the Organisational Culture and responses to Overcoming Resistance to Change. Answer: The concept of organisational culture involves a system of values, beliefs as well as shared assumptions. These values which are shared have a strong impact or influence on the individuals in the organisation as well as help to determine the way in which people perform their jobs as also the ways in which they dress and behave. The organizational culture helps an individual gain an insight into the insides of the particular organisation. The key to maintain a successful position in the global market is to meet the changing needs and modify the culture accordingly. According to the area of operation of a particular organisation it needs to work and allow the changes to its culture. It is quite obvious that the culture in an organisation will be based on the area in which it operates. Every organisation is bound to have its own unique characteristic as well as personality traits. In other words it can be said that the unique personality of any particular organisation is the culture of that particular organisation (Mazzucato Perez, 2014). There are several characteristics of organisational culture. The range of these characteristics is varied and can be said to vary from high to low. Their impact on the organisation is also varied. Innovation: Those particular companies whose cultures place high value on innovation encourage their employees in taking risks and as well ask them to innovate in their jobs as well as their performance. In case of companies where innovation is not encouraged, employees and workers are required to perform their jobs in the same way in which they have been trained to do them. Ways of improving their performance are not mentioned (Nordin et al., 2012). Attention to detail: Characteristics of organisational culture determines the degree to which the organisations employees are required to be accurate in their job (Waddell et al. 2013). In case of organisational culture that focuses on detail the workers are expected to do their work with precision as well as accuracy. Organisations that do not focus on precision do not ask their employees for precision (Vaara et al., 2012). Emphasis on outcome: Several organisational cultures involve the focus solely on the outcome or the output of the organisation. Very less importance is given to the nature in which the outputs are achieved. The value and value creation of the organisation is given sole importance. In case of organisations which pressurize there sales executives to get sales orders irrespective of any scenario, it an be said that the sole emphasis is on the outcome characteristic (Newman, 2012). Emphasis on the people: There are certain companies which give a high importance to the people and the impact of decisions on the people. For this reason huge importance is given to the decisions taken by the stalwarts in the organisation and the way in which it impacts the people. Teamwork: There are certain organisations that focus on the team work and the way the employees work together effectively. Teamwork is given a high priority in terms of organisational culture. In case of the companies, there is a positive and fruitful relationship between the employees and the managers. Aggressiveness: This nature of organisational culture helps to ascertain whether the members of the group in a particular organisation are required to be easygoing or assertive in the way they deal with their sole competitors in the marketplace. Companies having an aggressive culture place importance in the outperforming and competitive attitude of the company. Stability: This is an existent as well as important type of organisational culture in which the value is given on stability. These types of companies are more or less predictable, rule-oriented as well as bureaucratic in nature. Consistent and mostly predictable outcomes are provided by these companies (Mitchell, 2013). There may be both positive as well as negative extremes to organisational culture. In a positive aspect it acts as an emotional energizer. However in worst situations, it harms the productivity and performance of the organisation. Organisational culture can also be referred to as a form of adhesive that binds the entire operations of the organisation. It also helps to understand an organisation inside-out. It can also be said that organisational culture is its immune system (Huhtala et al., 2013). There may be certain external as well as internal organisational forces which impact a particular organisational culture. The resistance to change in an organisational culture is that instance when the employees of the organisation resist change when they sense the arrival of change and try to stop or resist it as they fear their position and do not want to jeopardize it. There are several reasons which might influence the employees of a particular organisation to resist the changes. The most important reason is the lack of communication. This is due to the fact that in many case the authorities responsible for taking decisions in a particular organisation may take important decisions involving change without informing the employees and this may lead to resistance of change by the employees. Sometimes the employees or the workers of the organisation are not consulted at all while taking decisions involving change in a particular company which might dissatisfy them and it is possible that they might resist change (Hayes, 2014). In some cases, several misunderstandings exist about the need for employing change in a particular organisation. Employees feel that there is not much need for change in an organisation. Some employees feel that the concept of change and its implementation is extremely fickle and there is a possibility of it being a temporary fad which might change or vanish as time passes. Errors or poor nature of communication may also lead to resistance faced from employees of an organisation. Untold changes in the routines may lead to anger within the employee circle and this may cause them to resist change. In several cases as well exhaustion or saturation may lead to resistance by the employees. In several cases employees fall prey to errors of their own thought processes (Carlstrm Ekman, 2012). They also feel that the risks faced in comparison to the benefits are more in number. It is also common notion that the company does not have the ability to implement the change. Mostly they feel that the changes which are implemented are bound to fail and the decisions will prove to be wrong. The proper management of change is not handled by the authorities. In some cases it is also believed that the changes are inconsistent with the values of the organisation. In severe cases even the trust on the authorities is shaken (Cadden, Marshall Cao, 2013). It is the nature of every individual to desire safety. More so in case of individuals of huge organisations where the ball game changes every single day, implementation of change is not well accepted. Fear of the unknown is also a huge factor which influences the resistance to change. Absence of good incentives as well as rewards might also lead to anger amongst the employees and this might lead to resistance on their part. It can be said that if an organisation wants to prosper it has to take its employees along. In order to ensure this the organisation has to stop the resistance to change which is common amongst the employees. There are several ways in which the employee resistance can be stopped. Employees need to be updated about the changes that the company aims to implement. Regular updates should be provided to the employees at team meetings and other seminars. New business strategies should be made known to each team of employees in the organisation. Everyone present in the organisation needs to understand the strategies of the company and only then will they contribute positively towards the benefit of the organisation. One member form each team should always be present at meetings and occasions of strategic discussions. These members should be the most expressive as well as vocal. Important and efficient persons should be present to help in the management of planning as well as implementation. Small and team wise goals should be created for the teams in the organisation (Grant, 2014). Finally successful implementation should be tied to compensatory benefits. Performance reports should be regulated and rewards and recognition should be given to individuals who perform these goals. There are several external and internal factors that implement the requirement for change in any organisation. The successful removal of negative impacts on a particular organisation leads to a better brand image. These might include both internal as well as external competition, failure to achieve goals, changes in the needs of the organisations target customers and many more. Finally it can be concluded that a company needs to understand the goals as well as the impact of the organisational change and lead to its successful management.

What factors made a person better at estimating the size of an angle or the length of a line Essay Example

What factors made a person better at estimating the size of an angle or the length of a line Essay From this data we made a hypothesis on what factors made a person better at estimating the size of an angle or the length of a line. My hypothesis was that year 10 pupils would be better at estimating both the size of angles and the length of lines than the adults and the year 7 children but adults answers will be closer to the mean on average. To prove this I would have to use the information in the spreadsheet .I first found the mean of angle 1 ,angle2 ,line 1 and line 2 in all of the sample of year ten all of the sample of year seven and all of the sample of the adults because using this I could find the average percentage error of each group because I felt this was essential in trying to prove the hypothesis I made earlier .The means for each were as displayed in the table below:Year 10Year 7AdultsAngle157.7665.4251.25Angle 2142.72141.04147.05Line 13.874.553.6275Line 214.5214.6112.7325At the moment when I produced the data it didnt interpret the data into what I wanted to know bu t I could find using the spreadsheet so first decided to find the percentage error of each group again using the calculation shown in the preliminary testing this was(difference between original and average estimates / actual size/length)* 100But first we thought that in the data there may be rogue results these are called outliers and are values that do not follow the data in a reasonable trend and so can be eliminated using a certain formula that creates upper and lower fences and if values fall outside of these two fences they can be classed as outliers and will be dismissed from the data . To implement this formula we need to find the upper and lower quartiles of the data, so by using Microsoft excel this data was found. The formula to find upper and lower fences to eliminate outliers is as follows:Lower Fence = Lower quartile 1.5 * inter quartile rangeUpper Fence = Upper quartile + 1.5 * inter quartile rangeFrom this we gained our upper and lower fences which wereYear 10Upper FenceLower fenceAngle 173.537.5Angle 2190110Line 15.51.625Line 222.37.7Then we did the same for year 7Year 7Upper FenceLower fenceAngle 192.532.5Angle 220585Line 17.251.25Line 219.57.5And for the adultsAdultsUpper FenceLower fenceAngle 16533Angle 2188.75110.75Line 15.51.625Line 26.87517.675With this data we deleted rogue values which amounted only to three.So now we can find the percentage error without worrying about rogue values influencing what could be a vital difference.Year 10 (%)Year 7 (%)Adults (%)Angle 17.218.96.8Angle 27.99.035.12Line 14.6232Line 216.1716.881.9This gives us an idea of to which group is better at estimating the sizes of angles and the lengths of lines but to see this in another way we can use box plots which are very useful for comparing sets of data from different groups within a certain population. The length of the whiskers can give an indication of how the data is skewed, either positively or negatively. Also the true value can be marked on to compare e ach of the medians to each other. By looking at the box plots , more specifically where the quartiles are marked we can see whether people tended to over estimate or under estimate. If the median is inclined slightly towards the upper quartile then people in that group under estimated more often than not and vice versa.So here are some box plots that compare all the age groups at both angles and lines.From this we see that the adults mean value is closer to the actual value of both angle 1 and angle 2 plus both the values of lines 1 and 2 ,this provides even more evidence to suggest against my hypothesis that years 10 pupils have a better ability at estimating both angles and lines because we have seen this through a percentage error and several box plot diagrams that we gained from using the averages from different groups but to prove my second statement in the prediction that adults estimates would be closer to their mean answer, which effectively means that adults made similar es timates to each other than the year 10 and 7 pupils , I need to use a statistical device called standard deviation this measures the spread of values from the mean, the bigger the value the more the answers are spread from the mean.Angle 1Angle 2Line 1Line 2Year 1011200.952.5Year 715301.53Adults1019.512.4We see the adults standard deviation figure being the smallest for three out of the four categories which proves one of my hypothesis statements correct but the other wrong this is because It was more of a guess than a prediction.Over all the taking all statistical methods used I came to the conclusion that adults were actually better at estimating both angles but it was interesting to see that the adults guesses had a small deviation from the mean (standard deviation) . The year 10 pupils by my calculations were second best ,their percentage errors were either very close to the adults in two out of four cases or dramatically a field from the other angle and line like the other two cases but their was a link between the angle and the line that were quite a bit out from the adult counterparts they were both the larger angles and lines using this information this could of provided another route of investigation to follow but then their was a factor preventing this being time and also looking at the year 7 data they were exactly the opposite to year ten pupils , where as they tended to be further out on the larger values of angle 2 and line 2 ,year 7 tended to be further out on the smaller sets of angle 1 and line 1 so their could have been a connection between this data and their ages or maybe gender but time did not permit us to investigate these fields.If I could reiterate the experiment I would make a more detailed hypothesis inducing me to analyse all possible fields that could of affected a persons ability to estimate the size of angles and lengths of lines an example of this is gender or intelligence but the field that I investigated which was age came out to me with a very clear result , this was that on average the older you are the better you are at estimating the size of an angle and the length of a line ,but we must take into account that we used a random sample of 25% from each group this meant that we could of missed some peoples estimates that could of affected or swayed the results to a different conclusion this could be important. This means the concluding statement may not actually be correct if further investigated with more detail and with more age groups such as year 8 , 9 and 11 but is still correct for the investigation we carried out.

By looking at the box plots , more specifically where the quartiles are marked we can see whether people tended to over estimate or under estimate. If the median is inclined slightly towards the upper quartile then people in that group under estimated more often than not and vice versa.So here are some box plots that compare all the age groups at both angles and lines.From this we see that the adults mean value is closer to the actual value of both angle 1 and angle 2 plus both the values of lines 1 and 2 ,this provides even more evidence to suggest against my hypothesis that years 10 pupils have a better ability at estimating both angles and lines because we have seen this through a percentage error and several box plot diagrams that we gained from using the averages from different groups but to prove my second statement in the prediction that adults estimates would be closer to their mean answer, which effectively means that adults made similar es timates to each other than the year 10 and 7 pupils , I need to use a statistical device called standard deviation this measures the spread of values from the mean, the bigger the value the more the answers are spread from the mean.Angle 1Angle 2Line 1Line 2Year 1011200.952.5Year 715301.53Adults1019.512.4We see the adults standard deviation figure being the smallest for three out of the four categories which proves one of my hypothesis statements correct but the other wrong this is because It was more of a guess than a prediction.Over all the taking all statistical methods used I came to the conclusion that adults were actually better at estimating both angles but it was interesting to see that the adults guesses had a small deviation from the mean (standard deviation) . The year 10 pupils by my calculations were second best ,their percentage errors were either very close to the adults in two out of four cases or dramatically a field from the other angle and line like the other two cases but their was a link between the angle and the line that were quite a bit out from the adult counterparts they were both the larger angles and lines using this information this could of provided another route of investigation to follow but then their was a factor preventing this being time and also looking at the year 7 data they were exactly the opposite to year ten pupils , where as they tended to be further out on the larger values of angle 2 and line 2 ,year 7 tended to be further out on the smaller sets of angle 1 and line 1 so their could have been a connection between this data and their ages or maybe gender but time did not permit us to investigate these fields.If I could reiterate the experiment I would make a more detailed hypothesis inducing me to analyse all possible fields that could of affected a persons ability to estimate the size of angles and lengths of lines an example of this is gender or intelligence but the field that I investigated which was age came out to me with a very clear result , this was that on average the older you are the better you are at estimating the size of an angle and the length of a line ,but we must take into account that we used a random sample of 25% from each group this meant that we could of missed some peoples estimates that could of affected or swayed the results to a different conclusion this could be important. This means the concluding statement may not actually be correct if further investigated with more detail and with more age groups such as year 8 , 9 and 11 but is still correct for the investigation we carried out.

Medieval Times Essays - Damascus, Damask, Linen, Chemise, Wool

Medieval Times What Was Clothing Like in the Middle Ages? In the Middle Ages the tailoring business developed and fashion as a concept was born. There wasn't much difference among the distinct social classes in the way the clothing were cut, the differences became evident mostly in the colours and materials. The country folk prepared their fabrics themselves and the nobility and the bourgeois had the possibility to buy their own imported fabrics. What Materials Were Used to Make the Clothing? The domestic wool was revised into cloths of different strengths -durable, felt and carded fabrics. The most expensive, the finest and the most colourful cloth was an extremely important merchandise imported for example from the Netherlands, England and Germany. Preparing the fabrics and the threads was a time-consuming and valuable craft. Fabric was extremely valuable despite whether or not it was homemade or imported. The medieval threads were spindled with a distaff (an early part of a spinning wheel). For one whole dress where the density of threads was 12 threads per centimetre you needed as much as 15 000 metres of finished thread; i.e. 30 kilometres of one-filament thread. The thread had to be tightly woven and very durable. The clothes were used all the way to the end -- the parts that were worn-out and broken were mended and patched. When the piece of clothing was totally worn-out, the good parts were used again. This might be a reason why the archeological findings are mostly church textiles. The looseness of the clothes was received by the using of gussets which were triangular inserts used to expand clothing. This way you could also save the valuable fabric. The colours were important to the contemporary people and by lifting the coating the colours of the underclothes and the lining could be shown. The working cloth of the country folk was a linen shirt. Long, dragging clothes were typical in the Middle Ages especially for the rich. Height was emphasised in clothes as well as in architecture. Buttons were first used in the 14th Century, however, they were more used in men's than in women's clothes. Armorial bearing shapes and mi-parti outfits (two different colour halves of clothing) were typical in the Middle Ages. What Did Women Wear? The quantity and quality of medieval woman's clothing depended mostly on status. Queens wore elaborate, exquisitely detailed gowns while peasants wore ill-fitting hand-me-downs. Noblewomen and the wives of wealthy merchants could afford more costly garments. A good example is Margherita Datini. A detailed list of Margherita's clothes from 1397 reveals what the average outfit would contain. The only undergarment consisted of a long dress, or shift. Since it had to be worn against the skin, this garment was usually made from a soft cotton or linen. This would be covered by a wool or fur petticoat during the winter months. Over the petticoat would be a long-sleeved gown. The surcoat covered the gown, but was sleeveless. The average wardrobe of the period contained very few gowns, but an assortment of surcoats made from various material. Margherita had a wide array to choose from; blue damask, taffeta, Oriental damask, and silk are only a few. Some of the surcoats had detachable sleeves, making the outfit versatile and adaptable to the seasons. Women also wore capes, cloaks, and shawls as wraps. They could be made from wool, fur, silk, or velvet. Some of these garments may have included hoods, but there were other types of headdresses. Margherita and other women wore wimples, which were cloths that covered the head, neck, and under the chin. The wimple was sometimes covered by a fur or cloth cap, or straw hat. Ladies wore shoes that were carved wooden bottoms with leather laces. Slippers might be made from silk, but were more often made of leather. The heel was shaped either from small blocks of wood, or from layers of leather. Other accessories included linen undersocks, long wool or silk hose, veils, purses, fans, and handkerchiefs. Lower classes of women had an extremely limited wardrobe. Most pieces were handed down through the family, or were the cast-offs from the lady of the manor. She may or may not have the linen undergarment, and the dress was usually made from as

Free Essays on Medicinal And Recreational Drug Use In The 20th Century

Medicinal and Recreational Drug Use in the 20th Century The 20th century spawned several cures for illnesses which have plagued mankind since the beginning of time. According to The History Channel’s website, in the 1800’s the average life expectancy was between 40 and 50 years old, but with the advances that medicine made in the 20th century those ages rose to nearly 80. In 1929 Dr. Alexander Fleming published his discovery of a drug called penicillin. Penicillin is a mold considered an antibiotic which prevents germs from reproducing. Fleming noticed that when coexisting with a colony of germs in a Petri dish the colony would not grow. This was a huge breakthrough in medical science for the 20th century. In 1938 Howard Florey, Ernst Chain and Norman Heatley refined the drug to make it usable for humans and to prevent infections from becoming dangerous. This so-called â€Å"Miracle Drug† prevented thousands of deaths during the Second World War by quickly killing bacterial infections soldiers got while in battle. Penicillin has also cured thousands of cases of pneumonia which until the time of antibiotics was a deadly virus. Amoxicillin is another form of penicillin which is often prescribed for infections of the tonsils or throat. In 1943 Selman Waksman discovered Streptomycin which was the first antibiotic effective against tuberculosis (TB ). The chance of dying from a bacterial infection today is only 1/20 of what it was in the early 1900’s because of the difference antibiotics. Over the counter drugs (OTC) are drugs that do not require a prescription to obtain. Generally such drugs are less powerful with smaller chances of side effects. Some common OTC drugs are often pain relievers (Antipyretic analgesics) such as Tylenol. Tylenol’s main ingredient is Acetaminophen which is found in fever reducers and pain relievers. Acetaminophen was approved by the FDA in 1951. Although side effects of this drug are not likely, t...

BP Global Oil Spill in Gulf of Mexico & Its Affect on Local Businesses Research Paper

BP Global Oil Spill in Gulf of Mexico & Its Affect on Local Businesses - Research Paper Example Gulf of Mexico has been a home for as many as 36 Marine Protected Areas (MPA) accounting for 13 % of total MPAs throughout the nation in addition to the MPAs of the bordering States of Alabama, Florida, Louisiana, Mississippi and Texas waters totaling 75 not included in the national mainstream MPAs. Florida Keys National Marine Sanctuary and Flower Garden Sanctuary have been threatened by the oil spill which could implicate British Petroleum under National Marine Sanctuaries Act. The coral reefs have also been damaged by the oil haze extending for about 22 miles from the Deepwater Horizon site. The Act makes it liable for damaging any living or nonliving resource of national marine sanctuary affecting its conservation, recreational, ecological, historical, educational, cultural, scientific or aesthetic value. The Act provides for imposition of civil penalties as high as $ 100,000 on any person and each day of violation constituting a separate violation. Apart from civil penalties, re sponse costs, damages due to destruction, loss or injury plus interest are leviable under the Act. There are also other Acts such as federal Endangered Species Act, Marine Mammal Protection Act which can make BP liable for deaths of dolphins and sea turtles as a result.1 Background The above said blowout occurred at the BP’s Macondo well in the Gulf of Mexico resulting in the deaths of 11 workers who were on Transocean’s Deepwater Horizon Drilling rig. An estimated 4.9 million barrels of oil were spilled in the process. The wellhead was 1,500 m down below the sea water. The United States declared a moratorium on deepwater drilling until October 12, 2010. It is widely believed that the blowout could have been prevented but for the poor quality of equipment meant to prevent blowout.2 Known as the last-line of defense, the blind shear ram on the blowout preventer fixed on well head on the ocean floor would have crushed the drill pipe thus preventing a blowout. The blind s hear ram is believed to have failed for want of checks as simple as verifying whether the batteries had been sufficiently charged. BP’s investigation team is reported to have held that the well had been poorly designed. Offshore Pollution Liability Association (OPOL) where membership is voluntary provides for only a maximum liability of $ 250,000which is insufficient given the magnitude of loss resulting from the Gulf of Mexico incident. Although OPOL membership is a pre-condition for drilling license, there is no rationale for a voluntary membership. This is apt to weaken the legal control of the polluters who would claim that damages to biodiversity and ecosystem are indirect and therefore no compensation is payable.3 Marine oil spills are not unavoidable accidents. Adverse environmental conditions or any catastrophic events cannot be attributed to oil spills.4 The offshore drilling unit at the Deep Water Horizon was worth$365 million capable of operating in deep waters as low as 8000 feet and drill further down up to 30,000 feet. The drilling unit had been engaged in drilling an exploratory well 41 miles off the coast of Louisiana at the time of accident. The well from which oil spill started on April 20, 2010 was finally capped on July 15, 2010. The total damages to the company, environment and the coastal economy have been placed at $ 36.9 billion. Apart from human error and equipment failure, the U.S. Government’s failure to respond with damage control measure, media
