EPA †Policy-making in the Federal System Essay Example for Free

EPA – Policy-making in the Federal System Essay The federal government enacted the Clean Air Act, so as to protect the citizens of the United States. At the same time Congress created the Environmental Protection Agency with its primary role of regulating and the enforcement of environmental policies at the state and tribal levels. A brief history on air pollution, in October 1928 in the industrial town of Donora Pennsylvania a thick cloud formed. This thick cloud lingered for five days, causing sickness in 6,000 and killing 20 of the town’s people. And in 1952, over 3,000 people died in London to what is known as the â€Å"Killer Fog†. These events alerted the federal government to the dangers that can come from air pollution and the public health issues that can arise from pollutants in the air. The original Clean Air Act of 1963 was passed, establishing funding for the study and cleaning of air pollution. The United States Environmental Protection Agency (EPA) was established and began operating on December 2, 1970. The EPA’s primary responsibility is enforcing and regulating the laws, these regulations and laws are for protecting the environment and public health. The EPA is a regulatory agency that Congress has authorizes to write regulation that explains the critical details that are necessary to implement environmental laws. (epa.gov/laws-regulation) The Clean Air Act 42 U.S.C.  §7401 et seq. (1970), regulated air emissions from stationary and mobile sources. With the approval of this Act the EPA was able to establish the National Ambient Air Quality Standards (NAAQS) which regulates emissions of hazardous air pollutants that can harm public health. The Energy Policy Act 42 USC  §13201 et seq. (2005) addressing energy  production in the United States, such as Energy efficiency; Renewable energy; Oil and gas; Coal; Nuclear matters; Vehicles and motor fuels. This Act provides loan guarantees for entities that develop or use inventive was that avoid producing greenhouse gases. Another provision of the Act increases the amount of biofuel that must be mixed with gasoline sold in the United States. (epa.gov/laws-regulation) America’s federal environmental laws set national standards, and on the condition that a state can shoulder the crucial task by enforcing these standards, they do by adopting laws that are as severe as the federal laws. Many states have assumed these responsibilities of enforcing the national standards by giving responsibility of specific programs throughout agencies within the state. The federal government is the overseer that enforces all cases and supervises the states’ activities while also monitoring state and the tribal operations of the Environmental Protection Agency programs. The Environmental Protection Agency supports the states and tribes to achieve effective enforcement and environmental compliance, and maintains support approved state programs through grant funds, and involvement. The Environmental Protection Agencies and state agencies make active efforts to educate the regulated community. A numerous compliance assistance tools have been put in place to help business, industry and state governments to conform to the environmental requirements. Web sites have been developed; hotlines, workshops, compliance training, fact sheets, and additional compliance guidelines are given to the regulated community. The Clean School Bus Program unites businesses, education, transportation, and public health organizations to encourage actions to stop the unnecessary idling of public schools busses. Modifying old schools busses with better emissions control technologies and proving cleaner fuels. The EPA is publishing a proposed rule designed to reduce air pollution, in 2017 the Tier 3 design would set new standards for vehicle emissions criteria and lessen the sulfur found in gasoline. This new rule would reduce tailpipe and evaporative emissions. The lower sulfur gasoline will improve  fuel economy by reducing gas consumption as well as reducing greenhouse gas (GHG) emissions. The Environmental Protection Agency seeks to provide a healthy environment. By partnership-building with states and communities the reduction of environmental pollutants becomes a joint venture.

Baroque Architecture Characteristics

Baroque Architecture Characteristics Introduction The Baroque period took the humanist Roman view of Renaissance architecture and showed it in a new rhetorical, theatrical and sculptural fashion they expressed the triumph of absolutist church and state. The main view of Baroque architecture was more concerned about color, light and shade, sculptural values and intensity which could be seen in its characteristics. Baroque is defined periods in literature as well as music; however critics perceived it to be unstructured, over ornamented, theatrical and grotesque. Although many things influenced the Baroque period it was also influenced by religion as well as the countries politics. Architects were interested in the space of the unfolding universe as well as the workings of the mind and attempted to portray passions of the soul through facial expressions. Features The features of the baroque era showed long, narrow naves that were replaced by a broader, or occasionally with circular forms. It displayed dramatic use of light that could be either strong light-and-shade contrast (known as chiaroscuro)effects; or they used uniform lighting by means of several windows. Another feature was opulent use of ornaments (puttos made of wood (often gilded), plaster or stucco, marble or faux finishing), they used large-scale ceiling frescoes and Baroques external faà §ade is often characterized by a dramatic central projection, however the interior is often no more than a shell for painting and sculpture which was seen in the late Baroque period. Baroque features also include illusory effects like trompe loeil and the blending of painting and architecture and in other countries such as Bavaria, Czech, Polish, and Ukrainian the Baroque style contained, pear domes that were are ubiquitous. Characteristics The main characteristics for the Baroque era were energy, great amounts of tension and a sense of movement from the buildings. Its painting, sculpture and architecture evolved from mannerism and broke away from the rules of contemporary architecture, they demanded freedom to plan, design and decorate their buildings with what they wanted. Columns had twisted shafts which were placed in front of pilasters surrounded by cornices and covered with curved and broken pediments. They contained â€Å"over the top† and often unsuitable details with carved decoration. Interiors had gilded sculptures often in awkward poses; the architecture was noted for its curved lines. Many of Baroques additions were finished in bronze, marble, gold and silver. Baroque had a dynamic look and feel to its design; it was a useful classification for isolating the tendencies and products of stylistic change. It was seen as spacious, brilliant, theatrical, passionate, sensual, ecstatic, opulent, extravagant , versatile and virtuoso. It was an age of expansion following on an age of discovery, its expansion led to still further discovery about architectural design and decoration. Section A: Interiors S.Maria Della Salute (1631-1682) The interior of S.Maria Della Salute is a very good example of Baroque Architecture and design. It displays the Baroque essence in a way but is not completely over ornamented nor does it contain any unsuitable details. Marble is mainly used in the columns and the base appears to be gilded in bronze. Sculptures are carved from marble and stand high in the round of the dome. An altar can be seen and one might assume it is also gilded in bronze. It is an artwork in a way but it is not â€Å"over the top† in any way which can be seen from this view point. S.Pietro (1656 – 1667) The S.Pietro is another great example of Baroque architecture and design. In this photo we can see the bronze altar that stands just in front of the apse, we can see paintings that are decorated with gold boarders, marble columns and high walls, the domes contain gold ceilings. Walls are decorated with sculptures in free standing positions in the walls also made of marble. Light is given through high standing windows and the main dome from above through a sky light. Versailles (1660 – 1685) The Palace of Versailles is the most well known piece of Baroque Architecture and design known to date. It defines what the baroque period was about. It was extravagant, sensual, dynamic, passionate (paintings), versatile and opulent. Decorations were not silver but pure gold. Soft fabrics, bright colours and beautiful sculptures decorated the interiors of the Palace. In the Hall of Mirrors as seen in figure 8 sculptures themselves were cast in gold high windows offered light and glass chandeliers hung from a ceiling decorated in painting and gilded gold boarders. In the Queens Chambers as seen in figure 7 one can tell that not even the bedrooms were kept simple. Gold was also used and to an extent it was overly used. The focus of ones eye is led to the gold decoration and not the architectural values of the building. The exterior as seen in figure 6 one can see that the balcony railings were gilded in gold decoration as the sun makes this easy to see. Marble is also used on the faà §ade of the building but it is mainly decorated in gold. Rich vibrant colours can be seen throughout the palace as seen in figure 7 of the Queens Chambers. Section B: Interior Design Although the Baroque era contributed to the great buildings we see today, one cannot forget about the interiors. Although lavishly decorated the interiors are very well designed to accommodate certain aspects. Architects need to think like that in order to obtain a good sense of what works and what does not. I believe interior design does actually hint about it along the lines. We design what we think the client would like and then get an idea if the client likes it of not, if not we simply make a few changes to get a better feel and a better view of what they want. It is the same now as it is then. Interior designers design the space in which the client will be in every day. It requires a great deal of insight and a knowledge about a person, one might consider reading your client by talking to them, when you do that you can get better ideas. Simple designs often make better designs in these days however in the past if it was big, spacious and contained lavish decorations it was clas sified as good. Conclusion So from looking at the baroque architecture one can say that it played a great role in the design of buildings today. Many people who obtain an over and above salary sometimes have one or two rooms that give remembrance to the baroque style. It was certainly lavish, dynamic and â€Å"over the top† decorations were definitely a bit much for today’s modern society. Bibliography Tansey, R.G Kleiner, F.S. 1954. Chapter 24.

Making Sense of a Change Management

Making Sense of a Change Management Change management is a systematic approach to dealing with change, both from the perspective of an organization and on the individual level. A somewhat ambiguous term, change management has at least three different aspects, including: adapting to change, controlling change, and effecting change. A proactive approach to dealing with change is at the core of all three aspects. For an organization, change management means defining and implementing procedures and/or technologies to deal with changes in the business environment and to profit from changing opportunities. Successful adaptation to change is as crucial within an organization as it is in the natural world. Just like plants and animals, organizations and the individuals in them inevitably encounter changing conditions that they are powerless to control. The more effectively you deal with change, the more likely you are to thrive. Adaptation might involve establishing a structured methodology for responding to changes in the business environment (such as a fluctuation in the economy, or a threat from a competitor) or establishing coping mechanisms for responding to changes in the workplace (such as new policies, or technologies). This book review is an attempt to understand the theoretical background for the changes that occur on individual as well as on organizational basis. The book Making Sense of Change Management: A complete Guide to the Models, Tools Techniques of Organizational Change written by Esther Cameron and Mike Green, highlights and explain different theories presented by the renowned businessmen, economists and educationists regarding different changing phenomenon appearing on the horizon of business world. Cameron and Greens objective for writing this book is to help their reader understand why change happens, how change happens, and what needs to be done to make change a more welcoming concept by carefully reviewing a wealth of resources that provide models, tools, and techniques of organizational change. Their purpose is not to explain how to plan and then implement a change initiative program. Rather the material presented in this book assist the readers to comprehend the change, its natu re, how it can be assessed and related to a particular situation and what type of outcomes can be carved out of the responses received on individual and organizational basis. Introduction of the Book The book Making Sense of Change Management: A complete Guide to the Models, Tools Techniques of Organizational Change is written by Esther Cameron and Mike Green. This book is about making sense of change management. The world we live in is continuously undergoing rapid changes at an intense rate. Each day dawns with a new invention, with an important discovery emerging from almost every field of life. The rate of change and discovery outpaces our potentials to keep up with them. The organization we work in or rely on to meet our needs and demands are also changing dramatically in terms of their strategies, their structures, their systems cultures, their boundaries and of course their expectations and responses to their stakeholders. This book and its writers Cameron and Green seems to hold the objective of helping their readers understand why change happens, how change happens, and what needs to be done to make change a more welcoming concept by carefully reviewing a wealth of resources that provide models, tools, and techniques of organizational change. Their purpose is not to explain how to plan and then implement a change initiative program instead of this their focus is on developing an understanding among their readers. The material in this volume is carefully organized within two parts. Part one, of this book is named as The Underpinning Theory and is comprised of first four chapters. Individual change is at the heart of everything that is achieved in organizations. Once individuals have the motivation to do something different, the whole world can begin to change[Individuals] are to some extent governed by the norms of the groups they belong to, and groups are bound together in a whole system of groups of people that interconnect in various habitual ways. So the story is not always that simple. Individuals, teams, and organizations all play a part in the process of change, and leaders have a particularly onerous responsibility: that is, making all this happen. Part Two The Applications is comprised of last four chapters (Chapters 5-8): In this Part, having looked at change and change management from three different perspectives (i.e. individual, team, and organization) and the roles, styles, and skills needed to become a successful leader of change, Cameron and Green apply this learning to specific types of change. They claim: We have identified four generic change scenarios, and we look at the particular management challenges involved in initiating and implementing each type of change. These change scenarios are structural, mergers and acquisitions, cultural, and IT-based process. Summary of the Book The very first chapter of the book draws together the key theories of how individuals go through change, using various models to explore the phenomenon. This chapter aims at providing managers and policy makers an insight and understanding of the change process and how it affects individuals and what strategies can be used to help the people to go through transition or transformation process without bearing a stress. Many of the change scenarios that you find yourself in require you to learn something new, or to adjust to a new way of operating, or to unlearn something. Buchanan and Huczynski (1985) define learning as the process of acquiring Knowledge through experience which leads to a change in behavior. Learning is not just an acquisition of knowledge, but the application of it through doing something different in the world. But learning to do something new usually involves a temporary dip (downfall) in the performance. When learning something new we tend to be more focus on that and become conscious of that change in our learning resulting in a change of our behavior. But once we have learnt that skill or has become habitual of that change our attention to that factor decreases and we are less conscious of it in other words we are unconsciously competent on that skill. There are four key schools of thought when considering individual change: The behaviorist approach is about changing the behaviors of others through reward and punishment. This leads to behavioral analysis and use of reward strategies. The cognitive approach states that the desired results can be achieved through positive reframing or the reinforcement of some desired attitudes. The writers believe that by setting goals and providing guidance and coaching to the employees or the people who are being affected by the change can ease the process of implementation of change. This approach link goal to motivation. The psychodynamic approach is about understanding and relating to the inner world of change. This is especially significant when people are going through highly affecting change. This approach treats people as individuals and understand their emotional states. The humanistic psychology approach in the personal development and growth of the employees by providing them a healthy atmosphere and fair chances to improve their skills to adapt to changing environment. The individuals history, the organizations history, the type of change and the consequence of the change are also key factors in an individuals response to change. Schein identified two competing anxieties in individual change: survival anxiety versus learning anxiety. Survival anxiety has to be greater than learning anxiety if a change is to happen. He advocated the need for managers to reduce peoples learning anxiety rather than their survival anxiety. The individuals in an organization work together sometimes in the form of groups or sometimes in the form of a team. Teams and groups have been differentiated in this book on the basis of their different characteristics and reasons for existence. Teams are considered more important for the organizations for accomplishing large or complex tasks. There are many types of organizational team, each with their significant benefits and downsides. Teams can be more effective by addressing five elements: Team mission, planning and goal setting; Team roles and responsibilities; Team operating processes; Team interpersonal relationships; Inter-team relationships; Teams relationships with the management. Teams are not built overnight. It takes time to develop as a team and have goal oriented affiliation among the team members. Tuckmans forming, storming, norming and performing model is useful for understanding the process. The team development process involves different leadership challenges at each stage. This book has made use of Bions work that highlights four possible pitfalls that need to be worked through. These are as follow: dependency fight or flight pairing cosiness The composition of a team is an important factor in determining how it can be successful. According to Belbin well-rounded teams work best. The Myers Briggs profile allows mutual of team members preferences for initiating or adapting to change whereas Belbins team types offer a way of analyzing a teams fitness for purpose and encouraging team members to do something about any significant gaps. The writers insist that the leaders should be aware of the type of team that can best suit the change process and how to manage that for effective and efficient achievement of the desired goals. Organizational behavior and assumptions how things really work are really important in determining the organizational response to change. This book deeply reviews the range of models and approaches developed by the significant authors in the field of business and socio-dynamics. The writers state that it is very important for the leaders and the individuals to understand their own assumptions about managing change, in order to challenge them and examine the possibilities offered by different assumptions. Comparisons of assumptions held by the employers and employees are very useful and increased understanding of each others perspective help to reduce frustration. Gareth Morgans work on organizational metaphors provides a useful way of looking at the range of assumptions that exist about how organizations work. The four most commonly used organizational metaphors are: The machine metaphor The machine metaphor is deeply ingrained in our ideas about how organizations run. According to it the project management and planning oriented approaches can be used to tackle the change. The political metaphor The political map of organizational life is recognized as vital key factor to organizational change. The organism metaphor This model is very prevalent in the human resource world, as it underpins much of the thinking that drove the creation of the HR function in organizations. The organism metaphor views change as a process of adapting to changes in the environment. The focus is on designing interventions to decrease resistance to change, and increase the forces for change. The metaphor of flux and transformation The metaphor for flux and transformation appears to model the true complexity of how change really happens. If we use this lens to view the organizational life it does not lead to a neat formulae or concise how to approaches. To be an effective manager we need to be flexible and select appropriate models and approaches for particular situations. Some of these models suggested in this book are as follow: Kurt Lewin three step model Bullock and Battens planned change approach Philip Kotters eight steps to change Beckhard and Harris change formula Nadler and Tushman Congruence model William Bridges model for managing the transition Carnalls change management model Senge systemic model Stacey and Shaw complex responsive processes. Different metaphors of change lead to different assumptions about what good leaders do. The writers of this book believe that the most effective ideas about change combine a number of metaphors, bringing the maximum benefits and avoiding the pitfalls of blinkered thinking. A popular notion of leadership is of the hero leader who leads from the front with determination, great vision and independence of mind. Bennis distinguished leadership from management and placed visionary leadership high on the agenda. Heifetz and Laurie and Jean Lipman-Blumen all argue against the need for visionary leadership. They advocate adaptive leadership which is about taking people out of their comfort zones, letting people feel external pressure and exposing conflict. Jean Lipman-Blumen instead emphasizes the need for leaders to ensure connectivity. Different metaphors of the change process imply different leadership roles. Senge advocates dispersed leadership, identifying three key types of leaders in an organizational system. If these three roles are in place and are well connected then change will happen naturally. Mary Beth ONeil names four key roles. Thoughts and actions i.e inner and outer leadership are both important for achieving organizational change. According to Kotter the hard work in the earlier stages of change process are vital for the success whereas Rosabeth Moss Kanter suggests that the harder part comes in the middle and the perseverance is necessary for success. Covey lists a set of principles and guidelines to help leaders to develop positive thinking pattern. The writers believe that the leader of change has to be courageous and self aware. He has to choose the right action at the right time and to keep a steady eye on the ball. However the leader cannot make the change happen alone. A team needs to be in place wit well thought out roles, and committed people. In this book the writers have identified four generic change scenarios and has looked at the particular management challenges involved in initiating and implementing each type of change. These change scenarios are: Structural change Mergers and acquisitions Cultural change IT- based change. Restructuring is an ever present phenomenon in todays organizations, though it could be highly unrewarding for those who initiates and those who experience it. But the leader needs to define the new changes with a clear vision and describe the objectives and goals of new structure, roles, and responsibilities, work processes for the individuals, interpersonal relationships in and out of the organization and new organizational and departmental strategies for the successful achievement of goals of organizational change. Mergers and acquisitions are another modern trend iof combating emerging environmental and technical changes. There are usually five main reasons for undertaking a merger or acquyisition: Growth Synergy Diversification Integration Deal doing Writer have suggested five golden rules for leaders to follow for effective mergers and acquisitions , which are as follow: communicate constantly get the structure right tackle the cultural issues keep customers on board use a clear overall process Culture is not just about induction programmes, it is everywhere in organizational life. Culture is vitally important for the organization because of its impact on performance. If the culture has to be changed we need to first develop an understanding about how it evolves. Schein (1999) suggests that there are six ways in which culture evolves. Some of these can be influenced by the leader and some cannot. A general evolution in which the organization adapt to its environment. A specific evolution of teams and sub-groups within the organization to their different environments. A guided evolution resulting from cultural insights on the part of leaders. A guided evolution through encouraging teams to learn from each other A planned and managed culture change through creation of parallel systems of project oriented task forces. A partial or total cultural destruction through new leadership. The writers suggest guidelines for achieving successful cultural change which is as follow: Always link to organizational vision, mission and objectives Create a sense of urgency and continually reinforce the need to change Attend to stake holder issues Build on the old and step into the new Generate enabling mechanisms create a community of focused and flexible leaders Insist on the collective ownership of the change. For having an IT-based change the organization needs to align organizational strategy with IT strategy other wise such changes will cause some major problems for the organization. My opinion about the book The book Making Sense of Change Management: A complete Guide to the Models, Tools Techniques of Organizational Change written by Esther Cameron and Mike Green, is about making sense of change management. The world we live in is continuously undergoing rapid changes at an intense rate. Each day dawns with a new invention, with an important discovery emerging from almost every field of life. The rate of change and discovery outpaces our potentials to keep up with them. The organization we work in or rely on to meet our needs and demands are also changing dramatically in terms of their strategies, their structures, their systems cultures, their boundaries and of course their expectations and responses to their stakeholders. This book and its writers Cameron and Green seems to hold the objective of helping their readers understand why change happens, how change happens, and what needs to be done to make change a more welcoming concept by carefully reviewing a wealth of resources that provide models, tools, and techniques of organizational change. Their purpose is not to explain how to plan and then implement a change initiative program instead of this their focus is on developing an understanding among their readers. The material in this volume is carefully organized within two parts. This book is a great resource for managers thrown into the midst of change, who need to gain understanding of what happens when you try to make significant changes in a business, and how best to manage people through it. This book is really helpful for leaders and managers in organizations to make sense of change management, providing insights into different frameworks and describing ways of approaching change at an individual, team, and organizational level. This book can be a guideline for any organization that needs to understand why change happens, how it happens and what needs to be done to make a change a welcome, rather than an unwelcome, visitor. It offers considered insights into the many frameworks, models and ways of approaching change and helps the reader to apply the right approach to each unique situation. This is a book that lives up to its titleit really does provide a toolkit to make sense of change. Every theory or main concept is accompanied by Stop and Think section where questions are listed to help the reader to reflect about what they have read in that section of the book. They also provide a chance to apply their theoretical knowledge to the real world situation and in this manner; way for cognitive and constructive learning is paved. The only thing which seems to be missing from this book is the case study. If each section or chapter is supplemented with a real world case study, this toolkit will become more effective and sharpen problem solving skills of the readers at one hand and an instant application of their learned skills on the other. Overall its an impressive practical book that will help managers who are looking for ideas rather than instruction. This is theoretically underpinned book on change which recognizes a multiplicity of perspectives.

AIDS :: Free AIDS Essays

Michelle Lee Pelletier & Sarah Smith December, 16, 1998 Mr. Marquis Honors Chemistry Aids A.I.D.S is an epidemic of the nineties. There are over one million people infected with the HIV in the United States, and over 250,000 cases of Aids. The World Health Organization estimates that there are between five and ten million infected with the H.I.V virus. This number is rising steadily. A.I.D.S is the end result of H.I.V, and to this day there is no cure. H.I.V was discovered in 1981, but not until 1984 was it proven to be the cause of A.I.D.S. Since then the definition of A.I.D.S. has changed many times, and will no doubt keep changing. And as people learn more about it, they seek out a cure. Scientist have been working hard on a cure for more than a decade. They have come up with many pill "cocktails" or other forms of medications, but so far the cure is still far away. People with A.I.D.S/HIV are running out of time, yet it seems that there is sadly till a lot of ignorance and misunderstanding of the disease, and without understanding a cure is pushed farther aw ay. Stealing a chance of survival from another person. The myths and truths need to be sorted out, a cure must be found, and the disease itself must be contained. The HIV virus was discovered in 1981. Compared to many other diseases that have had a relatively huge impact on mankind, it is relatively new. Cancers and so forth have been here since man. HIV was not connected to Aids, or proven to be the cause until 1984. Since The discovery it has gone through many changes, and many names. HIV was formally known as Lymphadenopathy-associated virus (lAV), Human T-Cell lymotropic virus type III (HTLV III). It is relatively new, which means that both AIDS and HIV are subjected to much change through the new few decades, we may know a significant amount about it at this time, but new information is learned everyday. The information behind the cause of Aids is inconclusive. Though it has been said the first case from a monkey in Africa, this may not be the story, but man did get the virus from monkeys. How they got it from the monkey is another thing. Perhaps the "monkey" (which is immune to the virus, which is believed to be because the mon key doesn't have co-receptors on it's white blood cells) had bleeding gums or had a higher content of HIV in its blood system.

Feedback Stress: Does Auditory Feedback Negatively Affect Performance o

The Stroop Effect In his historic study, Stroop found that reading names of colors interfered with individuals’ ability to name the ink color the word was printed in when the two differed (i.e., the word â€Å"BLUE† written in red ink) (1935). However, the basis of this phenomenon can be traced back to Cattell who found that naming colors and pictures took twice as long to accomplish than reading the word these colors or pictures represented (1886). He concluded that this was due to reading being an automatic process while identifying colors or pictures requires a conscious effort (Cattell, 1886). MacLeod (1991) reflects that it was Cattell’s work which strongly influenced future psychologist including Stroop. In his experiment, Stroop investigated how the reaction time to name colors increased when it conflicted with the automatic process of reading. He broke down his experiment into three parts. In the first, he tested how reading the name of a color printed in a different ink color (i.e., BLUE) differed from reading the name of a color printed in black ink (i.e., BLUE). The difference between the name of the color and the ink color it was printed in caused a slight interference resulting in an increased reaction time of 2.3 seconds (Stroop, 1935). In the second part of his experiment, Stroop (1935) looked at reaction time differences between naming the color of solid blocks (i.e., ââ€"   ââ€"   ââ€"   ââ€"   ââ€"  ) versus naming the color of the ink not the name of the color (i.e., responding â€Å"RED† for BLUE). He found that participants required 74% more time to name the color of the ink when it did not agree with the name of the color (Stroop, 1935). Stroop concluded that it was the interference between the automatic process of reading the na... ...a preliminary feedback intervention theory.

What is a sample?

Whereas a population is the entire group of objects that a certain researcher is interested in; a sample is defined as the fixed number of objects you get from a certain population. For example, Amelia wants to know if red flowers attract bees more than yellow flowers. In order to prove this assumption, Amelia takes a sample of a red flower (e. g. rose) and a yellow flower (e. g. a sunflower). There are lots of flowers that are red and yellow in color. Amelia could not afford to obtain every red and yellow flower in order to prove her assumption.Thus, it is practical for her to take a â€Å"representative† from all the red flowers and a â€Å"representative† from all the yellow flowers. Taking â€Å"representatives† from the entire population, you could now call these â€Å"samples†. It is essential to remember that the fundamental assumption underlying most of the theory of sampling is random sampling. This consists of the selection of individuals from th e population in such a way that each individual of the population has an equal chance of being selected. The process of such selection is called random sampling.The aim of the theory of sampling is to get as much information as possible, ideally all the information about the population from which the sample has been drawn. From the parent population, in particular, we would like to estimate the parameters of the population or specify the limits or ranges within which the population parameters are expected to lie with a specified degree of confidence. At work, we use sampling to prove or test something. For example, you want to determine if the new time management scheme will be beneficial to cut the costs on your company.So, as a manager, you could take some employees to undergo this new time management scheme in order to see if the new process is suitable for both the company and the employees. 2.

The normal distribution is the most commonly encountered distribution range in science. Random variables in normal distribution should be capable of assuming any value on the real number line, though this requirement is often not applied.For example, height at a given age for a given gender in a given racial group is adequately described by a normal random variable even though heights must be positive. A continuous random variable X, taking all real values in the range. The graph of variables with normal distribution is a symmetrical, bell-shaped curve, centered at its expected mean value. Typically, a binomial random variable is the number of successions in a series of trials in binomial distributions.For example, the number of ‘heads' occurring when a coin is tossed 50 times; thus a discrete random variable X is said to follow a binomial distribution with parameters n and p. However, the probability trials must meet the following requirements: a. the total number of trials is fixed in advance; b. there are just two outcomes of each trial; success and failure; c. the outcomes of all the trials are statistically independent; d. all the trials have the same probability of success. The similarity of normal and binomial distributions rely on the use of random variables as part of the data and their values could be both positive and negative.3. What do confidence intervals represent? Give an example of the use of a confidence interval. Before a simple research question could be resolved like, for instance, â€Å"What is the mean number of flowers that one person can remember? † it is necessary to specify the population of people to which this question will be addressed. The researcher could be interested in, for example, children under the age of 12 and girls. For the present example, assume the researcher is interested in all girls aged 9. Once the population is specified, the next step is t o take a random sample from it.In this example, let's say that a sample of 10 girls is drawn and each student's memory tested. The way to estimate the mean of all girls would be to compute the mean of the 10 girls in the sample. Indeed, the sample mean is an unbiased estimate of ? , the population mean. However, it will certainly not be a perfect estimate. By chance it is bound to be at least either a little bit too high or a little bit too low. For the estimate of ? to be of value, one must have some idea of how precise it is. That is, how close to ? is the estimate likely to be?So we use the confidence intervals to determine how close would be the unbiased estimate we have in our sample to the values that is indicated in the population mean. If the number of flowers that the 10 girls remembered were: 4, 4, 5, 5, 5, 6, 6, 7, 8, 9 then the estimated value of ? would be 5. 9 and the 95% confidence interval would range from 4. 71 to 7. 09. The wider the interval, the more confident yo u are that it contains the parameter you are interested in. The 99% confidence interval is therefore wider than the 95% confidence interval and extends from 4. 19 to 7. 61.

Attachment †Psychology Essay

Developmental Psychology Early Social Development: Attachment Attachment ï  ®Ã¢â‚¬ ¯ An emotional bond between two people. It is a two-way  process that endures over time. It leads to certain  behaviours such as clinging and proximity-seeking and  serves the function of protecting the infant. ï  ®Ã¢â‚¬ ¯ Primary attachment figure ï  ® The person who has formed the closest bond with a child,demonstrated by the intensity of the relationship. Usually  the biological mother, but other people can fulfil the role. ï  ®Ã¢â‚¬ ¯ Learning theory ï  ® A group of explanations which explain behaviour in terms  of learning rather than any innate or higher order  tendencies. Mainly used by behaviourists who rather focus  their explanations purely on what behaviour they observe. Learning Theory ï  ®Ã¢â‚¬ ¯Classical Conditioning (Pavlov) Unconditioned Stimulus (US) – food ↓ Unconditioned Response (UR) – pleasure ↓ Neutral Stimulus (NS) – the feeder ↓ Conditioned Stimulus (CS) – food from a feeder ↓ Conditioned Response (CR) – pleasure/attachment Learning Theory ï  ®Ã¢â‚¬ ¯ Operant Conditioning ï  ®Ã¢â‚¬ ¯ Reinforcement ï  ®Ã¢â‚¬ ¯ When doing something results in a pleasant  consequence, the behaviour is more likely to be produced. ï  ®Ã¢â‚¬ ¯ Punishment ï  ®Ã¢â‚¬ ¯ When doing something results in an unpleasant  consequence, the behaviour is unlikely to be produced. ï  ®Ã¢â‚¬ ¯ Dollard and Miller (1950) explain attachment using operant conditioning: ï  ®Ã¢â‚¬ ¯ When an infant is fed it reduces discomfort and increases pleasure, this serves as a reward and is the primary reinforcer. The person supplying the food is associated  with avoiding discomfort and is the source of reward which  becomes the secondary reinforcer. Attachment occurs  because the child seeks the person who supplies the  reward. Evaluating the Learning Theory ï  ®Ã¢â‚¬ ¯ Strengths It can provide adequate explanations of how attachments form. ï  ®Ã¢â‚¬ ¯ Behaviourists argue that since we are made up of the same building blocks of stimulus/response environments experiments done on animals are safe to generalize to human behaviour. ï  ®Ã¢â‚¬ ¯ Weakness ï  ®Ã¢â‚¬ ¯ It may be attention and responsiveness from the caregiver that is the primary reinforcer, not food. ï  ®Ã¢â‚¬ ¯ Learning theory is largely based on studies with non-human animals. Human behaviour may be similar in many ways but learning theory does not consider higher order thinking and emotions that can influence behaviour. ï  ®Ã¢â‚¬ ¯ Harlow (1959) demonstrated that it is not food but the level of contact and comfort the infant receives that increases attachment levels. The use of young rhesus monkeys were used to demonstrate this. ï  ®Ã¢â‚¬ ¯ 60 babies were studied in Glasgow and found that attachment was higher to the person who was most responsive and who interacted with them more (Schaffer and Emerson,1964). ï  ® ï  ® Cant explain the importance of sensitivity in attachment. Bowlby’s Attachment Theory (1969) ï  ®Ã¢â‚¬ ¯ ELEMENTS OF BOWLBY’S ATTACHMENT THEORY: ï  ®Ã¢â‚¬ ¯ Attachment is adaptive and innate ï  ®Ã¢â‚¬ ¯ Bowlby’s theory is an evolutionary theory because it sees attachment as a behaviour that adds to its survival and  ultimately its reproductive value. Having attachment  capabilities is an innate drive, similar to imprinting, that has long term benefits ensuring it stays close to its caregiver. ï  ®Ã¢â‚¬ ¯ Background on the Theory of Evolution ï  ®Ã¢â‚¬ ¯ Adaptive behaviours are behaviours that increase the  likelihood of survival and reproduction. ï  ®Ã¢â‚¬ ¯ Natural selection is the continuation of these adaptive traits within the animal to increase chances of survival. ï  ®Ã¢â‚¬ ¯ Sexual selection is the ability to reproduce, not just survive. Adaptive genes that lead to possessing traits to assist in  reproduction increases sexual selection. Bowlby’s Attachment Theory ï  ®Ã¢â‚¬ ¯ Sensitive Period ï  ®Ã¢â‚¬ ¯ A biologically determined period of time during the second quarter of the first year is the most crucial period in which attachments can be made. Once missed then it is more difficult for a child to make attachments and demonstrate social difficulties. ï  ®Ã¢â‚¬ ¯ Caregiving is adaptive ï  ®Ã¢â‚¬ ¯ Not only attachment but also caregiving is adaptively innate. Social releasers from the infant give signals to the caregiver (smiling, crying, etc) to take care of it. Attachment is the innate system in babies and caregiving is the innate system in adults. ï  ®Ã¢â‚¬ ¯ Secure base ï  ®Ã¢â‚¬ ¯ Having a secure attachment provides a child with a secure base in which to explore the world from. It fosters independence, not dependence. ï  ®Ã¢â‚¬ ¯ Monotropy and hierarchy ï  ®Ã¢â‚¬ ¯ Infants form a number of different attachments but has one particular bias towards a very special one called the primary attachment, this is called monotropy. Even with secondary attachments, this hierarchy of attachments recognizes the importance of a primary attachment figure (PAF). The PAF is one that responds most sensitively to the childs social releasers. Secondary attachments are important, without them, children tend to lack social skills. Bowlby’s Attachment Theory ï  ®Ã¢â‚¬ ¯ Internal working model ï  ®Ã¢â‚¬ ¯ A mental model of the world that enables individuals to predict and control their environment. The internal  working model based on attachment has several  consequences: ï  ®Ã¢â‚¬ ¯ In the short-term it gives the child insight into the caregivers behaviour and enables the child to influence  the caregivers behaviour so that a true partnership can be formed. ï  ®Ã¢â‚¬ ¯ In the long-term it acts as a template for all future relationships because it generates expectations about  how people behave. ï  ®Ã¢â‚¬ ¯ The continuity hypothesis ï  ®Ã¢â‚¬ ¯ The idea that emotionally secure infants go on to be  emotionally secure, trusting and socially confident adults. Evaluating Attachment Theory ï  ®Ã¢â‚¬ ¯ Strengths ï  ® ï  ® ï  ® ï  ® ï  ® Lorenz (1952) supports that imprinting is innate as the goslings imprinted on the first thing they saw moving, which was Lorenz. Research shows that once the sensitive period has passed and no attachments are formed, children display social difficulties with peers. If attachment and caregiving are an important biological function as Bowlby suggests then they would be found universally. Tronick et al (1992) studied an African tribe in Zaire and found despite tribal responsibility for raising kids a PAF is present. This is also evidence of monotropy. Schaffer and Emerson found that the more quickly a caregiver responded to a childs needs and the more interaction they had led to a stronger level of attachment. This interaction is important as it is not enough to have something to cuddle but to actually be cuddled back builds a stronger attachment. The Minnesota longitudinal study (2005) found that continuity between early attachment and later emotional/social behaviour. Infants classified as secure were later rated highest for social competence, less isolated, more empathetic and more popular. Evaluating Attachment Theory ï  ®Ã¢â‚¬ ¯ Weaknesses ï  ®Ã¢â‚¬ ¯ Multiple attachments, according to psychologists, are as equally important. There are no primary or secondary  attachments, all attachments are integrated into one single  working model. However, a review the research points to the  hierarchical model as being predominant (Prior and Glaser, ï  ® 2006). An alternative explanation to the continuity hypothesis exists, known as the temperament hypothesis. This is the belief that children form secure attachments simply because they have a more ‘easy’ temperament from birth, whereas more innately difficult children a more likely to form insecure attachments. The infants temperamental characteristics shapes a mothers level of responsiveness. Thomas and Chess (1977) identified infant personality types as easy, difficult and slow-to-warm-up. Belsky and Rovine (1987) found a link between physiological behaviours and later attachments types. The more calm and less anxious (aspects of temperament) an infant was the more likely they were to develop secure attachments. Types of Attachment ï  ®Ã¢â‚¬ ¯ The Strange Situation (Ainsworth and Wittig, 1969) http://www.youtube.com/watch?v=QTsewNrHUHU Aim: to see how infants behave under situations of stress  with the introduction of a stranger and the separation of  the parent. This tests stranger anxiety and separation  anxiety and also the infants willingness to explore with its secure base. Procedure: a 9Ãâ€"9 research room marked off into 16 squares  was used. The procedure consists of 8 episodes†¦ MEMORISE THEM!!! Data is collected by a group of observers that recorded  what the infant was doing every 15 seconds. Observer  noted the type of behaviour and level of intensity on a  scale of 1-7. Types of Attachment ï  ®Ã¢â‚¬ ¯ The Strange Situation Findings: ï  ®Ã¢â‚¬ ¯ Ainsworth  combined data from several studies to  make 106 middle-class infants observed. Similarities and differences were found in the way  the infants behaved. In terms of similarities, it was  noted that episode 2 onwards exploratory  behaviour decreased while crying increased. Proximity-seeking and contact-maintaining  increased during separation and when stranger  appeared. Finally, contact-resisting and proximityavoiding behaviours rarely occurred towards the caregiver prior to separation. Types of Attachment ï  ®Ã¢â‚¬ ¯ The Strange Situation Findings: ï  ® Ainsworth found differences in three main types of children. ï  ® ï  ® Insecure-avoidant: this is a style of attachment characterising those children that tend to avoid social interaction and intimacy with others. ï  ® ï  ® Secure attachment: this is a strong and contented attachment of an infant to his or her caregiver which develops as a result of sensitive responding by the caregiver to the infants needs. Insecure-resistant: this is a style of ambivalent attachment characterising  children who both seek and reject intimacy and social interaction. Main and Solomon (1986) re-analysed the strange situation video tapes and created a fourth attachment type: ï  ® Insecure-disorganised: these infants lack a coherent and consistent strategy for dealing with the stress of separation. Secure % of infants (Ainsworth, 1978) % of infants (Van Ijzendoorn et , 1999) Insecure avoidant Insecure resistant Insecure disorganised 66% 22% 12% XXX 62% 15% 9% 15% Evaluating Types of Attachment ï  ®Ã¢â‚¬ ¯ Strengths ï  ® Ainsworth’s Strange Situation technique has given psychologists a means to understand and study attachment which can lead to new future findings. ï  ® Intervention strategies have been developed to strengthen caregiving behaviour and attachments types. The Circle of Security Project (Cooper et al, 2005) which teaches caregivers to recognise signs of distress showed a decrease in disordered caregiving and an increase in secure attachment types. It has proven to be experimentally valid as its construct validity has been demonstrated by other studies supporting the four types of attachments and its predictive validity has been demonstrated in correlations between early attachment types and later behaviours. ï  ®Ã¢â‚¬ ¯ Its findings are also consistent which makes them reliable. Using interobserver reliablity methods, Ainsworth found almost perfect agreement at . 94 between the raters (1.0 is perfect). ï  ®Ã¢â‚¬ ¯ Weakness ï  ®Ã¢â‚¬ ¯ Or does it lack validity, because it is intended to measure the attachment type of an infant, BUT does it really simply measure the quality of a particular relationship? Main and Weston (1981) claim it is measuring one relationship instead of something innate within an individual. ï  ® Evaluating Types of Attachment ï  ®Ã¢â‚¬ ¯ Effects of attachment types ï  ®Ã¢â‚¬ ¯ Bowlby’s continuity hypothesis would predict that a child’s behaviour later in life would be effected by specific attachment types they develop. ï  ®Ã¢â‚¬ ¯ Prior and Glaser (2006) found that in later childhood, if as infants they developed a secure attachment type, they would  be less emotionally dependent and possess more  interpersonal harmony. Infants with the other three types  would be more aggressive, negative withdrawn in later  childhood. ï  ®Ã¢â‚¬ ¯ It would also effect you in your adult romantic lives as well. Hazen and Shaver (1987) conducted the ‘Love Quiz’ which  asked questions about early experiences and current love  experiences and found that there were characteristic  patterns of later romantic behaviour associated with each  early attachment type. Evaluating Types of Attachment ï  ®Ã¢â‚¬ ¯ Factors that influence attachment type ï  ® Sensitivity ï  ®Ã¢â‚¬ ¯ Ainsworth developed the Maternal Sensitivity Scale to rate mothers’ behaviour such as sensitivity and insensitivity to infants signals. The scale found: Securely  attached infant Observed  Mothers bx ï  ® ï  ® Insecurely attached infant Avoidant infant Resistant infant  more sensitive,  cooperating Unresponsive to  crying less  affectionate More rejecting and  less attention  giving Preoccupied with  routine activities when  holding infant Maternal reflective functioning ï  ®Ã¢â‚¬ ¯ Some studies have shown low correlations between measures of sensitivity and strength of attachment. Slade et al (2005) found the ability to understand what someone else is thinking or feeling may be more important. Temperament ï  ®Ã¢â‚¬ ¯ May play a role as previous research indicates, but it is unclear. Cultural Variations in Attachment ï  ®Ã¢â‚¬ ¯ KNOW the definitions of culture, cultural variations and the difference between individualistic and collectivistic cultures (pg.45) ï  ®Ã¢â‚¬ ¯ Cross-cultural Similarities ï  ®Ã¢â‚¬ ¯ Ainsworth’s Uganda study (1967) ï  ®Ã¢â‚¬ ¯ Tronick et al (1992) study on the African tribe in Zaire ï  ®Ã¢â‚¬ ¯ Fox (1977) infants in Isreali kibbutz raised by  nurses when tested in the Strange Situation  appeared equally attached to both caregivers,  except in the reunion behaviour where they  showed greater attachment to their mothers. Cultural Variations in Attachment ï  ®Ã¢â‚¬ ¯ Cross-cultural Differences ï  ®Ã¢â‚¬ ¯ Grossman and Grossman (1991) found that German infants appear more insecurely attached rather than secure. This may be due to the different childrearing practices as German culture involves keeping some interpersonal distance from the parent and infant. ï  ®Ã¢â‚¬ ¯ Takahashi (1990) used the Strange Situation on a group of 60 middle-class infants in Japan and found similar rates of secure attachment. However, the infants showed no evidence of insecure-avoidant and high rates of insecureresistance (32%). Different childrearing practices can explain the difference for in Japan the infants are rarely ever separated from their parents which is why they would be more distressed than their American counterparts. ï  ®Ã¢â‚¬ ¯ Conclusions ï  ®Ã¢â‚¬ ¯ These studies suggest that the strongest attachments are still formed with their mothers and that there are differences in attachment that can be related to differences in cultural attitudes. ï  ®Ã¢â‚¬ ¯ Meta-analysis study by Van IJzendoorn and Kroonenberg (1988) examined over 2000 Strange Situation classification studies in 8 countries. They found the variation between countries and culture were small with secure attachment being the most common in all countries followed by insecure-avoidant except in Japan and Israel. Variations within cultures however were greater. In conclusion the findings appear to be similar to that found in the US and this supports the view that attachment is an innate and biological process. Also data collected on different subcultures should not be generalised to be representative of a particular culture. Criticisms of Research on Cultural Variations ï  ®Ã¢â‚¬ ¯ Culture bias ï  ® ï  ® ï  ® Rothbaum et al (2000) argued that attachment theory and  research is not relevant to other countries because it is rooted in American culture. For example, the sensitivity hypothesis reflects western ideas of autonomy whereas in Japan sensitivity is about promoting dependence. The continuity hypothesis states that  secure infant attachments create more competent adults, however, this ‘competence’ is defined in terms of individuation. The secure base hypothesis in the west explains secure attached infants as independent and confident exploring whereas in Japan they  promote dependence and the concept of amae and so this can  explain why insecure-resistant behaviours are more typical. Rothbaum concludes that psychologists should produce a set of indigenous theories that are explanations of attachment that are rooted in individual cultures with a small group of universal principles (infant need for protection) but mostly with childcare practices relating to cultural values. Rothbaum was challenged by Posada and Jacobs (2001) which shows that attachment theory does apply to most cultures. Criticisms of Research on Cultural Variations ï  ®Ã¢â‚¬ ¯ Criticisms of cross-cultural research ï  ®Ã¢â‚¬ ¯ Tests  of procedures used may not be equally valid  in the country and may make the culture appear  Ã¢â‚¬Ëœinferior’ or ‘abnormal’. This is an example of  imposed etic. This is when a research method is  used in one culture even thought it was designed to  be used in another (intelligence tests or observations). ï  ®Ã¢â‚¬ ¯ The group that was tested may not be  representative of the culture and yet researchers  might make generalisations about the whole culture  or even the whole country. Disruption of Attachment ï  ®Ã¢â‚¬ ¯ Effects of Separation ï  ® ï  ® ï  ® ï  ® Spitz and Wolf (1946) observed 100 children in an institution became severely depressed after a few months. Skeels and Dye (1939) found similar children scored lower on intelligence tests. Bifulo et al (1992) found that negative effects of deprivation may occur later in life. When 249 women who had lost their mothers before they were 17 were studied, it was found that they were twice as likely to develop depressive/anxiety disorders later in life. Robertsons (1967-73) made films observing the effects of separation in children: ï  ® ï  ® When given a high level of emotional care and similar structures to that of their home life, the children exhibited some signs of distress, however, slept well and did not reject their PAF when they were reunited. Some were even reluctant to part with the foster mother which is a sign of a good emotional bond. John, however, was in a nursery and not given such attention. He became withdrawn and gave up on proximity seeking bx. When he was reunited with his mother he rejected her for months and demonstrated outbursts of anger towards her. Disruption of Attachment ï  ®Ã¢â‚¬ ¯ Physical and Emotional Disruption ï  ®Ã¢â‚¬ ¯ As the research evidence shows differences in the way physical and emotional attention is given can produce  negative effects in children. However, there are studies  that show these ill effects can be reversed. ï  ®Ã¢â‚¬ ¯ Sigvardsson (1979) studied over 600 adopted children in Sweden and at the age of eleven, 26% of them were  classified as ‘problem children’. However in a follow up study, ten years later they were no worse off than the  average population. ï  ®Ã¢â‚¬ ¯ So when alternative emotional care is provided, ill effects of separation can be reversed. However, for some  children disruption of attachment leads to permanent  difficulties. ï  ®Ã¢â‚¬ ¯ To criticise the validity of the research consider that they are based on case studies. Weakness of case studies are  that they are based on generalisations and they depend on  objectivity of the observers and are prone to observer bias. Failure to Form Attachment ï  ®Ã¢â‚¬ ¯ Isolated children ï  ®Ã¢â‚¬ ¯ Privation is the lack of having any attachments due to the failure to develop such attachments early in life. ï  ®Ã¢â‚¬ ¯ Genie ï  ® ï  ® The Czech twins ï  ® ï  ® Locked in a room by her father until she was 13. When discovered she could not stand erect or speak. She was disinterested in people and never recovered socially. Locked away by their step-mother until the age of 7. Were looked after by their sisters and by 14 had normal social and intellectual capabilities. By 20 they had above average intelligence and excellent social skills. Evaluation ï  ® Was unclear whether or not Genie was retarded at birth or if she ever formed an attachment with her mother. The Czech twins may have formed attachments to each other to compensate for complete lack of care. It is difficult to reach firm conclusions based on only these cases. Failure to Form Attachment ï  ®Ã¢â‚¬ ¯ Institutional Care ï  ® ï  ® Multiple studies show that the effects of institutionalisation within children is acute distress. Longitudinal studies have been conducted to see what long term effects are caused by institutionalisation. ï  ® ï  ® Hodges and Tizard (1989) followed a group of 65 British children from early life to adolescence. Children have been place in an institution from before they were 4 months old. Children have not yet formed attachments at this age. An early study found that 70% of the children were not able to care deeply for anyone. The children were assessed regularly up to the age of 16. Some children remained while most were adopted or restored with their original families. The restored children were less likely to develop an attachment with their mothers but the adopted ones were as closely attached to their adopted parents as the control group. However, both groups had problems with peers and showed signs of disinhibited attachment. These findings suggest that early privation had negative effects on the ability to form relationships even when given good subsequent emotional care. If failure to develop attachments after the sensitive period occur it can have an irreversible effect on emotional development. Failure to Form Attachment ï  ®Ã¢â‚¬ ¯ Effects of Privation and Institutionalisation ï  ®Ã¢â‚¬ ¯ Attachment disorder ï  ®Ã¢â‚¬ ¯ This has been recognised as a psychiatric condition and has been included in the DSMIV. There are two kinds of attachment disorder, inhibited and disinhibited. Children with an attachment disorder have no PAF, cant interact or relate to others before the age of 5 and have experienced severe neglect or frequent changes in caregivers. ï  ®Ã¢â‚¬ ¯ Poor parenting skills ï  ®Ã¢â‚¬ ¯ Harlow’s monkeys that were raised with surrogate mothers went on to become poor parents. Also, Quinton et al (1984) found similar findings when he compared 50 women who had been raised in institutions. When the women were in their 20’s the ex-institutionalised mothers were experiencing extreme difficulties acting as parents. ï  ®Ã¢â‚¬ ¯ Deprivation dwarfism ï  ®Ã¢â‚¬ ¯ Physical evidence by Gardner (1972) that institutionalised children are physically underdeveloped, potentially caused by stress hormones. ï  ®Ã¢â‚¬ ¯ Evaluation ï  ®Ã¢â‚¬ ¯ In the study of Romanian children, one-third recovered well despite not establishing a PAF prior to the sensitive period. Therefore, privation alone cannot explain negative outcomes. This suggests that damage occurs when there are multiple risk factors (Turner and Lloyd, 1995). ï  ®Ã¢â‚¬ ¯ Not sure if the children failed to form attachments early in life. Maybe they did and the problems they experienced later were more related to rejection. Impact of Day Care ï  ® ï  ® Day Care – the form of temporary care not given by the family or someone well known to the child and usually outside of the home. Social development – the aspect of a child’s growth concerned with the development of sociability, where the child learns to relate to others and with the process of socialisation, the child learns social skills appropriate to the society. ï  ®Ã¢â‚¬ ¯ Negative effects on social development ï  ®Ã¢â‚¬ ¯ Meta-analysis from findings of 88 studies supports Bowlby’s research that prolonged separation from the PAF leads to maladjustment. Violata and Russell (1994) concluded that regular day care for more than 20 hrs a week had an unmistakable negative effect on socio-emotional development, behaviour and attachment of young children. ï  ®Ã¢â‚¬ ¯ NICHD in USA conducted a longitudinal study of over 1000 children. Parents were interviewed regarding the effects of regular day care. The study showed  that the more time a child spent in day care, regardless of quality, the adults rated them as more disobedient and aggressive (NICHD, 2003). The children in day care were 3 times more likely to demonstrate behavioural problems than children that were cared by their mothers. Melhuish (2004) found evidence that children with high levels of day care in the first two years of development had elevated risks of developing anti-social behaviours. ï  ®Ã¢â‚¬ ¯ The Minnesota longitudinal study demonstrated the more securely attached infants are the more popular with peers they become. So therefore, the more insecure an infant, more peer related problems could be expected. Belsky and Rovine (1988) assessed attachment in children in day care and found that were more likely to be insecurely attached compared to children at home. Impact of Day Care ï  ®Ã¢â‚¬ ¯ Positive effects on social development ï  ® ï  ® ï  ® ï  ® ï  ® Good day care provides plenty of social stimulation, whereas, children living at home may lack social interactions. Brown and Harris (1978) found depressed mothers contributed  their low moods to being isolated at home with children. Depressed mothers are likely to form insecure attachments with their children which would have a negative effect on their children. Therefore, the independence gained with having a child in day care is a way to prevent this. Clarke-Stewart et al (1994) studied 150 children and found they were consistently more compliant and independent. The EPPE followed 3000 children in pre-schools and found increased sociability (Sylvia et al, 2003). Day care exposes children to their peers thus enabling them to develop social strategies (negotiate and make friends). Field (1991) found a positive correlation between the amount of time in day care and the number of friends children have once they enter school. Also, those that started day care before 6 months were more sociable than those that started later. Evaluating Research on Day Care ï  ®Ã¢â‚¬ ¯ Weaknesses of research on day care ï  ® When evaluating the research, one must consider the circumstances under which one can find positive or negative outcomes. ï  ® ï  ® ï  ® ï  ® Prodromidis (1995) found no correlation between Swedish children in day care and aggression. Freidman from NICHD explains the aggression study actually shows that day care children may be more aggressive than non-day care, but still 83% of children in day care between 10 -30 hours a week show no signs of aggression. Second important finding from the NICHD research is that the mothers sensitivity to the child, higher maternal education and income all play a more important role in decreased behavioural problems than the amount of time in day care. Finally, the findings are not causal. The data cannot show that day care caused aggression only that there is a link between the two. Therefore, the data suggests that childrens development is more strongly affected by factors at home than those in day care (Belsky et al, 2007). Evaluating Research on Day Care ï  ®Ã¢â‚¬ ¯ Weaknesses of Research on Day Care ï  ®Ã¢â‚¬ ¯ Cannot apply a cause relating to peer relations as  well, only a link. For example, shy and unsociable children have mothers that are shy and  unsociable, therefore, its possible that more  outgoing parents/children that go to day care. ï  ®Ã¢â‚¬ ¯ A lot of research supports the idea that day care  alone has no direct effect on development and  that there are other factors involved. Gregg et al  (2005) analysed findings from the Children of the  90’s study and concluded that for the majority of  children, maternal employment in their first 3  years of life had no adverse effects on behaviour. Evaluating Research on Day Care ï  ®Ã¢â‚¬ ¯ Mediating Factors ï  ® Quality of Care ï  ® ï  ® Individual Differences ï  ® ï  ® As the quality of care decreases it is expected that the attachment type will become poorer. NICHD study (1997) found that low-quality care was associated with poor social development. As parents have different interests in their child, day care staff are less invested and therefore provide a different kind of attention. This is reflected in Howes and Hamilton (1992) findings  that secure attachments  occurred in only 50% of day care staff but 70% in mothers. The NICHD study found the more secure a child’s attachment level is the better they cope with time spent in day care. However, another study showed that insecure children coped better than secure children (showed more aggressive bx) in day care. Child’s age and number of hours ï  ® ï  ® Gregg et al (2005) found that negative effects were more likely to be found in children starting day care before 18 months of age. However, the magnitude of these effects was small. Clarke-Stewart et al (1994) found no difference in attachment between spending a lot of time in day care (more than 30 hours) with those that spend a little time (less than 10 hours). Implications of Research into Attachment and Day care ï  ®Ã¢â‚¬ ¯ Attachment Research ï  ®Ã¢â‚¬ ¯ Attachment research has shown that when separation occurs, negative effects of this separation can be avoided if substitute emotional care can be provided and links to the PAF are made available. This research has changed the way hospitals handle visiting arrangements and the way institutional care is provided. ï  ®Ã¢â‚¬ ¯ A second implication is the way the adoptions process is managed allowing babies to be adopted earlier strengthening child/parent attachments (Singer, 1985). ï  ®Ã¢â‚¬ ¯ Another implication is the improvement of parenting skills, ie, Circle of Security, which improves infant/mother relationships. ï  ®Ã¢â‚¬ ¯ Finally, attachment research has been used to improve day care quality focusing on the importance of secondary attachment figures. ï  ®Ã¢â‚¬ ¯ Day Care Research ï  ®Ã¢â‚¬ ¯ As research shows, high quality care leads to positive outcomes. What is highquality care? ï  ®Ã¢â‚¬ ¯ Low child-staff ratios – 3:1 is ideal for sensitive care to be given ï  ®Ã¢â‚¬ ¯ Minimal staff turnover – allows for consistent care and decreases anxiety ï  ®Ã¢â‚¬ ¯ Sensitive emotional care – only 23% of carers demonstrated highly sensitive care, 50% was moderate care and 20% were emotionally detached. ï  ®Ã¢â‚¬ ¯ Qualified staff – qualified managers lead to better social development ï  ®Ã¢â‚¬ ¯ To ensure high-quality care, legal standards are implemented relating to staff ratio to age of the child, minimum qualifications of staff, Ofsted inspections and finally the sure Start programme.
