Article Review I Am On The Couch - 1426 Words
~Unapologize~ Clarke sat on the couch in her motherââ¬â¢s house staring blindly at the half finished sketch in front of her. She couldnââ¬â¢t sleep, she couldnââ¬â¢t even think properly, the scene outside her home replaying in her mind over and over on repeat. Lexa had told her she loved her, and then she apologized and ran away. She reminded herself as the terrified expression of her girlfriend flashed through her mind. Why did she apologize? Did she get nervous? Or what if she just got caught up in the moment and didnââ¬â¢t mean it? Maybe sheââ¬â¢s just been humoring me with our relationship, maybe she wants to break up with me and is just too nice to break up with me like thatâ⬠¦ What if sheââ¬â¢s already found someone else and is just looking for a way toâ⬠¦show more contentâ⬠¦Somewhere in the back of her mind she wondered who was calling on her at this time of night but her brain was preoccupied with a jumble of thoughts that kept switching from Mufasa to her own father to Lexa and back to Mufasa so fast she couldnââ¬â¢t think straight. And the fact she wasnââ¬â¢t thinking rushed back to her all at once when she pulled the door and came face-to-face with her clearly nervous girlfriend who looked close to panicking just standing there. And I look like a total mess right now. ~Unapologize~ Lexa stood in next to the front door and froze. All of her previous insecurities flooding back into her system as she stood trembling in front of the massive door. Come on Woodsâ⬠¦ You can do thisâ⬠¦ Youââ¬â¢re just talking to your girlfriendâ⬠¦ Who you told not three hours ago that you love her and then fled the sceneâ⬠¦ Yeahâ⬠¦ Piece of cakeâ⬠¦ Lexa pressed the doorbell and it took every ounce of courage she had stored in her body not to bolt from the steps and back into the safety of her car. She ran what she wanted to say over again in her head, she would apologize for apologizing earlier and tell her that she could ignore what she said and did to whatever degree necessary for their relationship to move forward as it had been previously. However every word she had planned to say fledShow MoreRelatedChildhood Obesity and Its Effect1260 Words à |à 6 Pagesstatus (Wang, F. and Veugelers, P. J., 2008).

The Invisible Man By Ralph Ellison Essay - 2164 Words
Racism is prevalent throughout history. There has always been one group of people who believed they were better than other groups. Racism for a long time seemed to be a taboo. The topic could not be discussed because if it was, it meant people were trying to rebel against the status quo. Protest literature emerged from the Harlem Renaissance in the 1920ââ¬â¢s to 1930ââ¬â¢s. Protest literature is used to address real socio-political issues and express objections against them. In his novel, The Invisible Man, Ralph Ellison exposes the racism in society by focusing on the culture, in regards to the expected assimilation of African Americans and how the time period largely influenced the mistreatment of the African American population. He also uses symbols to show how African Americans were viewed in society. The third key principle of race, ethnicity and post-colonial analysis centers on a groupââ¬â¢s culture being erased in order to adapt to the ââ¬Å"newâ⬠dominant culture (Hall 269-271). The group being affected may try to hold on to established traditions, but may face a divide in their ranks. The older generations are more likely to cling on to established cultural traditions, but the new generations will try to adapt to the new one society presents to them. Ellison gives examples of the divide in the African American community. ââ¬Å"He was brought up along with the members of a country quartet to sing what the officials called ââ¬Å"their primitive spiritualsâ⬠when we assembled in the chapel onShow MoreRelatedInvisible Man By Ralph Ellison1366 Words à |à 6 Pagesfighter left standing, amidst unbridled carnage.

Psychology and Globalization Complex Relationship
Question: Discuss about the Psychology and Globalization for Complex Relationship. Answer: Introduction: The world has become a global village over the years. With the introduction of globalization in every aspect of life, the world has become small. Life has changed drastically across continents. Economies have taken a large leap towards growth. Globalization refers to the process of communication and integration among the citizens, organizations, governments of different countries, driven by trade and investment and supported by information technology. Globalization has impacts on economy, culture, environment, political systems, economic development and well-being of societies throughout the world (Knight, 2015). For thousands of years, people have indulged in travelling across the countries and continents for the need of buying and selling products, which is the base for todays international trade and globalization. As nations developed, organizations formed and they have invested in companies in other countries. The trend has grown multiple times after the First World War (1906). C ountries entered into agreements for international trade and other economic policies for the benefit of the global economy (Collier Venables, 2012). Today, economies have developed a lot due to this wave of globalization. In regards to this, we will discuss the effects of globalization on a multinational company, Costco (Retail Supermarket). Costco and globalization: Costco Wholesale Corporation is an American warehouse club, which provides merchandise of various products of various brands at substantially cheaper prices. It is designed to assist the small-to-medium sized businesses for reducing cost of purchasing. Individuals can also buy from Costco provided they have membership. It is a membership-only multinational retail supermarket. Currently, Costco is the largest membership-only warehouse club in US, and second-largest in the world, after Walmart. It is headquartered in Issaquah, Washington. As of Nov 20, 2016, Costco operates 723 branches all over the world, including 8 in Australia. In 2015, it has sold approximately $1.3 billion worth of merchandise in Australia (Minahan, Huddleston Bianchi, 2012). Costco Wholesale Australia Pty Ltd is the Australian section of the Costco USA. It is headquartered in Lidcombe, New South Wales and has employee strength of 2355 approximately. Costco operates in retail industries of supermarkets and grocery stores, fuel and consumer goods in Australia. According to The Australian, approximately 150,000 Australians have taken Costco membership since the opening of its first local store in 2009 in Melbournes Docklands (Minahan, Huddleston Bianchi, 2012). Costco first began its operation in Seattle, Washington in 1983. It merged with The Price Company in October 1993 and formed Price/Costco, Inc., and brought about the membership-only concept in their business. Price Enterprises changed its name to Costco Corporations in 1997. In 1999, Costco Companies Inc. changed its name to Costco Wholesale Corporation, listed as COST in NASDAQ. It has started to spread its operations in the international market since early 2000s. Now it has branches in USA, UK, Canada, Mexico, Australia, Japan, South Korea, Taiwan and Spain (Minahan, Huddleston Bianchi, 2012). Costco is one example of globalization of retail industry. It started as an American corporation, but overtime it followed the globalization process to become a multinational retail warehouse giant. In the new century, integration and interdependency of international economies started, to achieve more prosperity within obligatory rules by the government, imposed to avoid the problems that arise in an open market. This promoted semi-global markets and led the way for globalization of markets. Studies on cross-border integration and other factors show todays globalization level is only 10 to 15 percent (Grinin, 2012). Aspects of globalization: There are two aspects of globalization the globalization of markets and the globalization of production. Globalization of market refers to the assimilation of distinct and diverse national markets into one international market. The organizations with chain outlets represent this type of globalization, for example, Cocacola, Starbucks, KFC, MacDonalds, Walmart and many more. Costco also falls under this category. On the other hand, globalization of production refers to the acquisition of factors of production from places around the world to gain the benefit of the cost differences and quality of the factors. Companies do this to lower their cost of production and supply quality products in the domestic and international markets. Volkswagen, Boeing and many computer hardware companies fall under this category (Herrera, 2012). In the past few decades, there have been significant developments in the economic policies and technologies, which led to a increase in international trade and investments. Migration also increased leading to economic development of nations. For instance, international trade volume has risen by 20 times since 1950, and, in two years, from 1997 to 1999, the flow of foreign investment got almost doubled, from $468 billion to $827 billion. Thomas Friedman represented this wave of globalization as farther, faster, cheaper and deeper (Herrera, 2012). Globalization also led to liberalization of economies. Post Second World War, especially in the past two decades, nations have started to adopt trade liberalization policies. That led to increasing production capacity and new scope for trade and investments across the globe. Governments entered into agreements to reduce the commercial barriers and promoting trade and investment in foreign countries (Grinin, 2012). Hence, to take the chances for new opportunities in the foreign markets, organizations started to invest, build factories, produce and make marketing arrangements to capture the international customer base (Marsella, 2012). Costco has applied this logic in its operations. It studied the foreign markets and took the opportunity to expand in the international markets with different product merchandise. To understand the impact of globalization on the business operations of Costco, let us first have a glance on its business strategies. It sells bulk products at a lower price. The small to medium sized businesses and large families are the target customers. Costco does not carry multiple brands, apart from their home brand, Kirkland Signature label. This allows Costco to buy from a single vendor, thus lowering the price and marketing cost even more. A general Costco store carries approximately 3,700 distinct product varieties compared to a Walmart supercenter with approximately 1,40,000 varieties (Mora, 2016). It also does not store packing bags to lower its operating costs. Customers need to carry their own bags for shopping. Lighting costs are reduced on the sunny days to make maximum use of the sunlight during the daytime (Lukic, 2016). Costco uses shipping pallets to display products on the floor, rather than stacking them on the individual shelves (Minahan, Huddleston Bianchi, 2012). Effects of globalization: Australia adopted globalization in the 1980s. The economy was declining and unemployment rate was high prior to globalization. It has allowed foreign companies and investors to invest here freely, open up businesses, which led to efficient economy, competitive markets, improved quality of output, creation of jobs and thus, higher employment rate, innovation in technology and improvement in the living standards (Patel, 2017). We will discuss the effects of globalization in regards to the business operations of Costco. There has been increase in foreign investments in the country. Agreements with other nations led to opening of the economy for FDI s and trade relations (Martinez-Fernandez et al., 2012). Exports and imports both have increased significantly. For instance, Costco is a US-based corporation. While expanding its business, it has captured the economic scope of Australia and opened its first branch in Docklands, Melbourne in 2009 (Courtemanche Carden, 2014). Rate of employment increased in the economy. Since there has been a rise in the opening up of businesses, naturally more jobs were created in all the sectors like manufacturing, agriculture, service, mining (Jaumotte, Lall Papageorgiou, 2013). For example, with 8 branches in Australia, Costco has generated employment of approximately 2355 persons country-wide till date (Price, 2016). As a result of this growth in employment, living standards have improved, people have more money in their hands and liquidity has increased in the market. Hence, Costco has found it feasible to expand its stores in 8 locations in the country. People are now willing to spend money to maintain their living standards, which led to increased level of sales in the retail sector. Costco is a retail supermarket, selling multiple varieties of product in bulk and at a lower price. The supply vendors of Costco have experienced a surge in their manufacturing of the products and they sustain in the manufacturing industry by supplying to Costco only. Costco has followed the policy of diversification of investments in all their business strategy. They operate as a retail supermarket for all types of consumer goods including fuel. Since it is a multinational company, it can easily shelf a particular brand of a particular product from a different country. Exports and imports have become easier after emergence of globalization (Price, 2016). Problems: Studies on Costco have thrown some insights on its aspects. They face a few problems. Following are the major problem Faced: Variable membership cost Costco membership price is $60. People buy membership at $60, some never use it for inconvenience to shop, and some spend unnecessary more money to make worth of the $60. Individuals do not become interested to buy the membership due to the constraint of buying large. Since their price margin is very low, they must make part of their profit from the memberships. However, the price should be different for individuals and small families; and small-to-medium sized businesses and large families (Yang et al., 2016). Costco fuel is cheaper than its rivals. Even if its 15 cents less, people are lured by the small savings (Hinterhuber Liozu, 2014). They are willing to drive long way to save this little amount, because there are not many fuel stations of Costco. Costco sells in bulk. That is good for small-to-medium sized businesses and large families but not for small entities. Most of the time, people avoid going there due to the constraint of buying in bulk (Samuel, Shah Sahay, 2012). Costco is unbeatable for some non-perishable goods like pet food, toiletries, but not for some other things like food items. Buying in bulk ultimately leads to wastage of money and the product as well (Samuel, Shah Sahay, 2012). Recomendations: Costco has a wide range of problems. Following are a few recommendations that may help solve such problems. Costco must categorize the target customers and charge accordingly in order to make more people interested to buy the membership. Costco should open up more fuel stations and advertise their lower prices. Costco should introduce an option for buying little less, so that the customer base increases. Costco should put more emphasis on advertising its lower prices. Since, it is a competitive market, it is important to make customers aware about the offers and price discounts of the stores. To thrive in the industry and make profit, not only prices should be lower, but that has to be properly advertised also. Costco should opt for a viable operating strategy where there would be less wastage of resources (Samuel, Shah Sahay, 2012). Conclusion: Globalization has shaped the diverse Australian economy into an emerging and blooming one. It has impacts on all aspects of a business. In this highly competitive market, a company must take the global aspect of markets into consideration. The effect varies from one industry to the other. The dealings between countries also vary, so does the impacts on the businesses. There are other factors also which have impacts on the international and domestic business such as, culture, legal factors, immigration, terrorism, technological advancements, and infrastructural developments and so on. All of these together has led to an efficient and competitive economy. Organizations are improving their way of business and marketing which ultimately helps to achieve economic growth, and benefits the consumers most. In the discussion above, the effects of globalization on the company, Costco Wholesale Corporation, Australia, have been emphasized. Costco, a multibillion-dollar multinational wholesale w arehouse club, has taken the wholesale retail business to a new level. Knowledge of the Australian market and innovation of business strategies and marketing plans have helped them grow outside of the USA. This is a major effect of the globalization and the resultant trade agreements between the nations. References: Collier, P., Venables, A. J. (2012).

Interpersonal Communication and Conflict Negotiation
Question: Discuss about the Interpersonal Communication and Conflict Negotiation. Answer: Introduction Interpersonal communication possesses a direct influence on the organizational culture. Interpersonal communications play an important role in the business environment of an organization. According to Knapp et al. (2014), the confusion and misunderstandings can be considered as significant factors that can damage the business environment and an ultimate failure of the company within the industry. This particular discourse will discuss the essential factors that affect interpersonal communication. This study will also reveal the consequences of the cultural misunderstandings in the business environment. Employees of the business organization work together for sharing a special kind of bonding in order to deliver their best job performances. The maintenance of proper and adequate interpersonal communications helps the associated stakeholders to reduce and avoid any cultural misunderstandings as it can damage the positivity of the workplace and the business environment. On the other han d, interpersonal communication possesses enough capabilities for making a healthy interpersonal relationship and creating positive ambiance. Discussion As opined by Wood (2015), the concept of culture and interpersonal communication is closely associated with the sensitivity to the cultural differences. The economic condition of a company depends on the basic ability to communicate in an efficient and effective manner across various cultures. However, there is a huge contradiction regarding the influence of technology has made the interpersonal communication easier than the traditional mode of trading. Even the use of internet has made the process of intercultural communication easy as the multinational corporations can collect relevant news related to the business across the world. The perception of self in the interpersonal communication plays a pivotal responsibility for communicating with the rest of the world. The perception of self in interpersonal communication examines and identifies the core relationship in between the fundamental concepts of the communication and the self-identity. It helps to learn about the traits of an adaptive and self-aware communicator. Biocca and Levy (2013) have mentioned that the perception of self in interpersonal communication provides the facts on self-esteem. With the proper interpersonal communication, an individual can explore various paths of improving own communication skill and style in order to deal with other individuals from different cultural background within the workplace. There are different types of perceptions regarding the self in interpersonal communication and this perception possesses several stages. An individual should find out the ultimate consequences of the self-satisfying prophecies in the entire communication process. An individual can consist own thoughts and feelings regarding own strengths and weakness. Madianou and Miller (2013) have referred that from the social comparison, own evaluation and interpretation, others images concerning the particular individual and the actual cultural teaching process help to develop the perception of self in interpersonal communication. Interpersonal communication suggests the process with which the people exchange relevant information and feelings through verbal and non-verbal messages. Interpersonal communication of an individual involves not only the transmitting process of the messages; however, it also includes the facial expressions, tone of the voice, body languages and gestures. According to Berger (2014), the elements of the interpersonal communication suggest the communicators, messages, context and feedback. The implication of the interpersonal communication includes the process of collecting and providing relevant information. On the other hand, the culture and interpersonal communication influence the behavior and the attitudes of the individuals. With the proper employment of the interpersonal communication, an individual is capable of forming important contacts and to maintain appropriate relationships with the making sense of the world and its notion of experiences. Interpersonal communication also helps to express the personal requirements and there is constant growing of the sense of understanding the requirements of the other associated employees within the organization. Berger (2014) has suggested that interpersonal communication can be considered as irreversible, inescapable and complicated, however, it is necessary for the psychological, relational, environmental, cultural and situational context. In this essay, there will be a discussion on the cultural context, which engages all of the learned rules and behaviors that may affect the process of interaction or communication. It is noteworthy to mention here that the cultural aspects differ from one country to another. Interpersonal communication helps to earn the process of dealing with the individuals from different cultural background (Fussell and Kreuz 2014). Listening can be understood as the most fundamental component of the interpersonal communication skills. The skill of active listening can be improved and acquired with the practices. There are contradictions related to the active listening process as it is difficult to master and will and it takes patience and time for development. Concentration is the key component of active listening as it involves every sense and notion in order to provide a full attention to the message of the speaker. The listener should be conscious during the decision-making process and there should be capability of the listener for understanding the actual messages of the speaker. Active listening always promotes the non-judgmental and neutral decision. Hewes (2013) has determined that active listening considers the short periods and the patience pauses of the silence during the communication. Active listening always provides scope and opportunities to explore the feelings and thoughts of the message provide rs. It has been assessed that the procedure of active listening does not focus solely on the speaker and its messages; however, it reveals both the verbal and non-verbal signs of the listening. The non-verbal signs of active listening can be determined by smile, posture, eye contact, and distraction and mirroring. Hearing and listening cannot be considered as same thing and in order to be a good and patient listener, an individual should possess much more than letting in the audible stimuli. Often people fail to consider the impish link in between the necessity of the interpersonal communication for making a strong and stable bond with others. On the other hand, Monaghan et al. (2012) have mentioned that listening suggests a learned communication skill. It is often difficult to understand the characteristics of a good listener, however, it can be understood when another person is not listening to the former person. As opined by Hynes (2012), listening is a transactional and dynamic process of receiving the message and responds to the recalling or the other messages from the sender. In the interpersonal communication, an individual usually makes sense of the received messages of another communicator. Listening has been determined as dynamic only because it plays a pivotal role in the interperso nal communication. On the other hand, listening has been concerned as transactional as both the receiver and sender of the message are active agents in the entire process. Some of the critics have criticized the process of listening as a two-way street as it merely reveals the fact that listening is necessary, however, it is insufficient for maintaining the relationships in between the sender and the receiver of the messages. The major four components of the listening process consist of receiving, responding, recalling and rating. Verbal, nonverbal, emotional and conversational messages are significant for mitigating the consequences of the cultural understandings in the business environment of an origination. It has been evidenced that every individual employs a vast range of the paralinguistic mechanisms and nonverbal messages for expressing own emotion. All of the non-verbal and emotional messages can be concerned the facial gestures, facial expressions, tone of the voice and postures. In todays competitive business world, the business experts utilize not only the verbal communication, however, concentrates on the non-verbal and emotional messages as it can be determined to interact with the other persons in proper manner. However, there are still contradictions regarding the implication of nonverbal messages as it often fails to reveal the intense emotional state of an individual. As opined by Tzonis et al. (2012), during the crucial decisionmaking a session, it is next to impossible to communicate with th e emotional or non-verbal messages. On the other hand, the non-verbal communication shows the intentional signals of the emotional condition and reveals the limited value of communication with the help of emotions in this rational world. The interpersonal communication involves much more than the exact meaning of the words than the conveyed messages or the information. A nonverbal message suggests implicit messages, which are expressed through the non-verbal behaviors of an individual. On the other hand, a non-verbal message conveys the fundamental relationship in between two people and provides feedback to the other person. Emotional communication regulates the fundamental glow of the communication process by signaling to other individuals. Manning (2014) has referred that the non-verbal communication is an integral and complex part of the entire communication styles and skills. In most o the cases, the people are unaware of their own non-verbal behavior and fails to understand its necessity in the interpersonal commu nication for reducing any issues related to the cultural misunderstandings in the business environment. Burnside-Lawry (2012) has suggested that the verbal communication has been proved as an effective interpersonal communication instead of the implication of the non-verbal or the emotional communication process. However, the effective use of non-verbal communication can be learned from the experts as it can develop the communication styles and skills of the individual. The conversational messages involve greeting, phatic communication, such as small talk, establishment of relevant connection for opening channels for further interaction. Conversational messages can be denoted with the sets of conversation, relatively informal type of social interaction. The consequences of the cultural misunderstandings have a large impact on the individuals and the business operations of an origination. It is essential for the management and higher authority of the company to overcome any kind of issues related to the cultural misunderstanding with employing potential communication skills. In order to mitigate the cultural differences, the management should learn at first the process of dealing with people from various cultural backgrounds. The different cultural background can be determined by completely different mannerisms, gestures, and customs. Cultural misunderstandings also possess the language barriers and the tone of the voice (Weger et al. 2014). For instances, the nations like Germany and America, a business associate interacts in aggressive or assertive tone in order to share their ideas or suggestions. On the other hand, In Japan and China, a person speaks in a soft and passive manner for communication. During the marketing campaign or launching a new product, there may be some problems regarding the cultural misunderstanding because of different cultures. Some cultures possess a strong sense and notion of nationalism for conducting business in other countries in this era of globalization. On the other hand, there are effective recommendations for mitigating issues that evolved from cultural misunderstandings (Wolvin 2013). Technology enables every individual to stay connected with the other and it reduces the cultural misunderstandings in an efficient manner. The video conferencing and the international phone calls help to solve the cultural misunderstandings and the conflicts. From various researches, it has been revealed that to maintain a potential communication with the individuals from different cultures is challenging. The cultures provide individuals with different ways of thinking, hearing, seeing and interpreting the entire world. In this era of globalization, diverse cultures influence collides and mix together. Considering the basic degree of today's business world, the knowledge and skills of culture and mentality require essential skills to deal business functions. Intercultural contact enhances the potentiality of an individual and helps an organization to continue its business in the international market (Hung and Lin 2013). Conclusion This particular study clearly discusses several factors in detailed manner that are responsible for the interpersonal communications. It also outlines the ultimate consequences of the cultural misunderstandings in the business environments. This essay concentrates on the culture and several aspects of the interpersonal communication. At the end of the study, it can be understood that in order to avoid any kind of conflict, it is the best policy for avoiding any political discussion and negative discussion on the cultural aspects. In this study, there is also mention of type of barriers of interpersonal communication, which may influence the performance of an employee and ultimately of the entire business activities of an organization. There are recommendations to mitigate such issues related to the interpersonal communication in a proper manner. References Berger, C.R. ed., 2014.Interpersonal communication(Vol. 6).

Lord Of The Flies Essays - English-language Films, Films
Lord Of The Flies ?The Lord of the Flies is a picture of our society today.? Discuss the statement and show the way the statement applies The Lord of the Flies is about a mini-society of boys formed by chance. Their isolation from adults forced reality upon them and so they had to think for themselves and work together. As a commentary of today's society it does well to explain some of today's issues like violence, laws, pride, greed, fear, religious power and the conflict between living in a civilized society or savagery. It is all about the choice the boys made when life became real. In the beginning their lives were controlled and protected by their parents, teachers and police officers. Jack cannot kill the pig even though he can eat meat because of the ?enormity of the knife descending and cutting into living flesh.? (p 41). Roger cannot hit the boys with the stones even though he could if he wanted to because he has been conditioned by the society he used to live in. This is the type of society the children live in. Everything is a game until the beast. The beast signals the end of the games and start of reality. Lives are at stake in perspective of the boys and survival must occur in any form. Our society is much like this as today's society is also about survival and what choices we make to survive. The mini-society started off peaceful. The purpose was to set a signal fire and live off fruit until help came. The conflict came when the fire and hunting could not be committed to at the same time. As the fire was a 24 hour task and hunting needed the whole party, the party started to take sides. Ralph's fire would be the sensible thing to do to get rescued however hunting would lift the standard of living for all the boys and would also be a luxury, recreational event. The fire was hard work and immediate results were none even though long-term results would be better. The hunting side wins eventually. In Australia today we are spending beyond our ability to afford this spending. This means we have a great influx of goods and services but as a community we are cheating ourselves as this leads to a current account deficit and the cost of living in this deficit must be paid plus the deficit. In this book's case, the deficit was their morals and the interest was paid in life. The conch was the symbol of power and it represented the order in the beginning of the book. It brought them together and provided laws for the society. The main law being whoever holds it has the right to speak without interjection or disrespect while he was speaking. It is much like a policeman's badge or even the mace in our parliament. However, the beast held a greater power over the conch which was fear. It is used by Jack to gain power over the rest of the group. His promises and rallies to kill the beast eased the fear of the boys and hence he won over the group. The killing of Simon as the beast but saying the beast was still alive, showed Jack had used the beast to keep his power as leader of the tribe. In a way, it became a religion as Jack's ritual of killing pigs for their heads to keep the beast happy. This was his method of promoting hunting. Other examples of this in real society are the Vikings whose promise of Valhalla made them among the best warriors of all time in the world. In today's society, religions can give power and money to many people. Fear of gods or protection from all fears in society can make person donate to a religious unit material goods or loyalty. Even traditional religions like Catholicism can allow the leaders to lead a life of luxury. Violence in the book increases as it does in society today. At first, the intention of killing the first pig was there and then when a pig was finally killed, killing became easier. The restraint that deemed killing unacceptable in society was broken. Next

Principal methods for healthcare research Introduction Principal methods for healthcare research IntroductionTheir Respective Research Design and philosophyThe Contrastingà Research HypothesizesApproaches to samplingData Collection Methods and Data analysisQuality of studiesCriteria to establish rigor in qualitative methods. Patton (2002) p.552-558Study:Jeppson et al (2003)Binge and Purge Processes in Bulimia Nervosa: A Qualitative StudyMy interpretationQuestionDiscussionRelated Introduction Bulimia Nervosa (BN) is an eating disorder, which is characterised by repeated episodes of over eating and bingeing and by a set ofà compensatory behaviours intended to cause weight loss which includes vomiting, purging, fasting and excessive exercise. The American Psychiatric society (A.P.A. DSM-IV, 2000) and the World Health Organisation ( World Health Organization. International Statistical Classification of Diseases, 10th Revision (ICD-10). Geneva, Switzerland: W.H.O., 1992),à both suggest the following diagnostic criteria for the disorder 1. A persistent preoccupation with eating and irresistible craving for food. 2 .Repeated episodes of binging/overeating in which large quantities /amounts of food areà consumed 3. Patients experiencing BN take excessive measures to compensate for the ââ¬Ëfatteningââ¬Ëà à effects of food e.g. vomiting, purging and fasting. The Beating Eating Disorder Association (BEAT). Formerly known as the Eating Disorders Association, a voluntary sector group in the UK., as provided figures that up to 1.15 million people in the UK, experience a significant problem with BN, and up to 90.000 people are receiving treatment at any one time. It is not therefore surprising that BN is a major and widespreadà problem. Consequently a number of treatments have been developed and trialled, based on focused research, and developing an evidence base. The National Institute of Clinical Excellence (NICE). Published guidance in 2004, (Eating disorders: Core interventions in the treatment and management of anorexia nervosa, bulimia nervosa and related eating disorders. London: National Institute for Health and Clinical Excellence (NICE) 2004). Which recommends Cognitive Behavioural therapy (CBT) as an efficacious treatment as well as Selective Serotonin Re-uptake Inhibitors (SSRIââ¬â¢s) such as Fluoxetine. Research in this area is an important on a number of counts. Firstly, on clinical intervention grounds so that the treatment offered for the disorder can be expanded and improved and secondly given that the Disorder was only recognised in 1979 ( Russell, G.1979), and with a widespread epidemiology, sufferers experiences of t he disorder are important in clinical practice to deepen understanding of sufferers experiences.. The two papers presented here both focus on the condition from different perspectives andà ask different questions. The first paper is a qualitative study: Binge and purge Processes in Bulimia Nervosa: A Qualitative Investigation (Jeppson et al. 2003) using a grounded theory design focusing on the two core diagnostic behaviours of BN; binging and purging. They aimed to elucidate information on these processes and their function for Bulimicââ¬â¢s experience. The second paper is a comparative intervention study, following a quantitative research design aà form of Randomised Control Trial (RCT) Cognitive-Behavioural, Fluoxetine and Combined Treatment for Bulimia Nervosa: Short- and Long-term Results (Jacobi et al.2002). Both papers illustrate their design paradigms and contain a number of flaws, which will be discussed in relation to their respective research methods. Their Respective Research Design and philosophy Jeppson et al(2003), deployed a qualitative research design, which followed a grounded theory approach (Glaser Strauss,1967). Grounded theory was originally developed by these social researchers, before the approach ââ¬Ësplitââ¬â¢ into different camps, (Stebbins, R.A., 2001),à the approach essentially emphasizes the ââ¬â¢generation of theoryââ¬â¢ from data that is acquired in the actual process of conducting the research. So rather than beginning with an hypothesis that needs to be testedà that is the hallmark of the experimental quantitative research design, grounded theory begins the research process with an aim for exploration. The quantitative paradigm illustrated by the Jacobi et al. (2002) paper, forms the basis of RCTââ¬â¢s and Therapy trials which are common in much of health care research, including Cognitive Behavioural Therapy (CBT) and treatment approaches/interventions to Bulimia Nervosa.à At its philosophical ââ¬Ëcoreââ¬â¢ is the notion of empiricism (Owen, F. Jones R, 1977), whereby quantitative properties and phenomena and their relationships are observed and studied. Thus the process of measurement is crucial to the paradigm and this affords the connection between ââ¬Ëempiricalââ¬â¢ observations i.e did X effect Y and mathematics, through the expression of quantitative relationships As measurement is crucial to the quantitative paradigm, the choice of Randomised Comparison Study is entirely appropriate for the Jacobi investigation, as it wants to compare the treatment effects of three different conditions treating the disorder. Studies of this type are a form of scientific experiment, with RCTââ¬â¢s often referred to as the ââ¬Ëgold standardââ¬â¢ for intervention studies (Cartwright, A. 2007). They are often used for ââ¬Ësafetyââ¬â¢ studies in drug trials and for testing the effectivenessà of clinical interventions and services The two research studies presented here, display different philosophical foundations, which shape their whole approach to research deign. The Contrastingà Research Hypothesizes Jeppson et al (2003), developed an aim for their qualitative study based on previous research they had encountered on the BN binge-purge process that is seen to be central to the disorder. The study was not concerned with assessing the ââ¬Ëeffectsââ¬â¢ of interventions on binge and purge behaviour, but rather to try and understand what these behaviours meant and the functions they served for the patients they studied. They considered in previous research that quantitative methods, had focused on self-monitoring of these episodes and ranking them to ââ¬Ëmeasureââ¬â¢ links to mental state e.g. Stress, and had deemed that it had not sufficiently led to an understanding of their function as experienced by BN patients themselves. They had an idea that these behaviours were crucial and played a part in assisting sufferers with their ââ¬Ëemotional regulationââ¬â¢, but were curious and wished to expand an understanding of their role. They therefore set out with an ââ¬Ëaimââ¬â¢ for the research to find out what BN patients experiences of these two processes and the meanings /function they served for them, I believe this ââ¬Ëaimââ¬â¢ was entirely congruent with the qualitative method, and provided a question that RCTs looking at interventions had not and could not study. The Jacobi et al., paper(2002),à asked a different set of questions. They were interested in how CBT compared with the SSRI Fluoxetine, and a combination of them both .à They considered that both the psychological (Wilson, G.T., Fairburn, C.G., 1993) and pharmacological interventions (Goldstein et al.,1995) had developed an evidence base for treating BN. They designed an ambitious study to investigate the question of the relative short and long-term effectiveness of the three interventions. They questioned whether the combined approach would be more beneficial in the long-term, as previous research studies investigating a combination approach, had experienced high drop-out rates due to the side effects of the of the SSRI, which may have influenced their results. The study did not include a control or placebo condition, which would be the normal procedure for intervention type studies.The reason for this was that they consideredà previous research had demonstrated the effectiveness of CBT andà Fluoxetine, and was not needed. The study had four aims: To compare the effectiveness of CBT, Fluoxetine and there combination, to compare the short and long-term effects of these treatments. To inquire about the possible ââ¬Ëadditiveââ¬â¢ effect of combined intervention and to examine the differential effects of the treatments. These types of intervention question are suitable for a randomised study as the questions Jacobi and team are asking are essentially ones of intervention and differential effectiveness/measurement on a number of variables e.g. Binging and purging episodes, short and long term effects as ascertained by validated psychological questionnaires and clinical interview. Approaches to sampling It is generally considered that sample size is generally much smaller in qualitative studies than those recruited for quantitative studies such as RCTââ¬â¢s (Cresswell,J.W., 2003).à As qualitative studies are generally smaller in size, criticisms have been leveled at this paradigm. Although the paradigm does not seek to study the ââ¬Ëtotalââ¬Ë population, issues surrounding diversity and variation within a population are often cited (Jones,2007). The Jeppson study used only eight participants The approach to sampling used in the study is importantà as the process of selecting participants is relevant to the aims of the study.à They used purposeful sampling to generate the data for their enquiry. Purposeful sampling generally refers to the selection of participants who have experience or knowledge of the area under investigation (Procter et al, 2010) As all participants were selected with a specific diagnosis of BN (APA., DSM-IV,1994) they would all currently have experiences of the processes under investigation. They were recruited from a suburban area in Utah, USA., Descriptive information, including socio economic variation, inpatient and out patient status and educational information was given.à à This form of sampling used in the study is not random or based on statistical probability as in quantitative studies. Sampling in quantitative research design, especially RCTââ¬â¢s, differs. This type of sampling is in essence the selection of of observable units, which can be measured (Maxim, P.S., 1999). As outlined in the introduction, BN is widespread in the UK (and other european countries). It is not possible in the Jacobi study to observe the effects of the treatment interventions with the whole population of people experiencing BN. Therefore quantitative studies tend to study a sample of the group or population which may represent the larger population. The study recruited its patents by a mixture of media advert and direct referral to the Department of Psychology at the University of Hamburg. All underwent telephone screening, by a clinician not involved in the study (to assess inclusion criteria) and a semi structured psychiatric interview,and physical examination As selecting people for therapy trials isà open to sampling errors, in thatà some people selected,may be ââ¬Ëexceptionalââ¬â¢ or ââ¬Ëdifferentââ¬â¢ from those of the larger ââ¬ËBulimicââ¬â¢ population.The method attempts minimize these possibilities, by careful inclusion/exclusion criteria and the random distribution ofà the participants into one of the three treatment conditions[1] The size of sample for the Jacobi study is more important than the qualitative study, to gain meaningful results. Data Collection Methods and Data analysis The Jeppson et al study (2003) study, collected its data from interviewing eight participants who agreed to take part in the study, by using a semi-structured interview format, lasting one hour. The semi-structured format differs from a more limited ââ¬Ëformalizedââ¬â¢ set of questions, by nature of its flexibility. It allows for new questions to be added in response to what the interviewee says, inviting and generating further information, which the study utilised. The study used a ââ¬Ëframeworkââ¬â¢ and ââ¬Ëinterview guideââ¬â¢, which is a collection or set of topics to guide the interview process (Lindlof Taylor, 2002). The paper, makes reference to this, but does not provide specific details of what constituted the ââ¬Ëguide. To enhance validity, ââ¬Ëmember checksââ¬â¢ were conducted post interview, all participants received a 20 minute phone call, where findings were ââ¬Ësharedââ¬â¢; allowing corrective feedback on accuracy. Transcripts were also read by three mental health professionals The study reported that ââ¬Ëredundancyââ¬â¢ or theoretical saturation occurred between interview 5-7. Grounded theory employs this framework, so sampling frameà may be modified as a result of a process deemed, ââ¬Ëconstant comparison analysisââ¬â¢ i.e, that data is determined by its recurrence and re-evaluation to assist with the ââ¬Ëtheorizingà processââ¬â¢ of the area under investigation. The type of process involved in theà purposeful sampling used in Jeppsons study, accepts that it is impossible to identify ahead of time, all categories of emergent data that the researcher needs to review.à So its is purposely designed to pursue data collection categories to the point of concept or ââ¬Ëdata saturationââ¬â¢, which occurs when the dataà is stable and the pattern(s) unlikely to change (Locke,2001). They found this occurred during the interviewersà 5-7, and added 1 further interview according to protocol. (Lincoln Guba, 1985) Onceà Jeppson collected the data, key points were assigned (or marked) to it, referred to as ââ¬Ëcodesââ¬â¢. Concepts and categories were then then worked out. The categories that emerged are seen within this methodology as the basis of theory generation for the study. This process as been referred to by Glaser and Strauss (1967) as the reverse emergence ââ¬Ëhypothesisââ¬â¢.à Thus, it was considered that to gain information on the participants binge and purging behaviours it was best to ask them about their experiences so as generate theory from their responses, rather than to come to the study with a pre-determined hypothesis or theory which needed testing. As the researcher is part of the ââ¬Ëresearch processââ¬â¢ and data collection, ââ¬Ëreflexivityââ¬â¢, is a feature of the data collection process. This can be divided into ââ¬Ëpersonal reflexivityââ¬â¢ and ââ¬Ëepistemological reflexivityââ¬â¢. ââ¬ËPersonal reflexivityââ¬â¢ involves the researcher being aware and examining their own values, experiences etc. and how this may have shaped the research. It also involves thinking about how the research may have affected and possibly changed people and researchers. ââ¬ËEpistemological reflexivityââ¬â¢ as such, asksà how the research question is defined and conducted and how it may of limited what was found? by askingà searching questions about the data and its findings (Willig,C. 2001). Jeppson notes, that he was ââ¬Ëawareââ¬â¢ of himself and the potential influence on the study. Jacobi, collected its data by using a battery ofà validated Psychological Measures to assess outcomes from the three intervention conditions.They were administered at pre and post treatment, andà at 3 months and one year follow up. Descriptive statistics[2] were given using the mean[3]à and standard deviation[4] of patients with regard to age, marital status, andà education. Frequency of binging and vomiting, onset of these behaviours , lowest BMI etc., no table provided. Data analysis was conducted by using a number of inferential statistical tests, to ââ¬Ëmeasureââ¬â¢ and quantify a host of possible influences on the outcome results obtained form the measures of each condition. Individual one-way analyses of variance ( ANOVAs) were used to compare data, i.e., demographics, clinical variables:à frequency of binging etc pre and post.à The ANOVA technique involves measuring the variance of the group means and comparing that to the variance predicted if all groups were randomly sampledà from the same population i.e ANOVA, tests hypotheses about the mean(s) of a dependent variable(s) e.g frequency of binge eating across the different treatment groups, in relation to the independent variables i.e. group condition To analyze the differential effects of the 3 treatments is was originally proposed to use uni and multivariate analyses of covariance[5], e.g .to study the covariance of say mood state with frequency of purging across the treatment conditions, to see if the amount of change between two or more variable maps changes in another variable, an estimate of correlation.[6] Sample size, through attrition was assessed as to small to run theses tests, at one year follow up. The ANOVAs and MANOVA tests used in this study produce the F-statistic[7], which is used to calculate the P-value,[8] and significance. The choice of tests was appropriate[9], given 3 treatment conditions, and the comparative nature of the research question/hypotheses. Aà intention to treat analysis, conducted for drop-outs was in line with the research protocol for this study design. Quality of studies The two papers have approached the subject of BN from different research designs. It is important when consideringà research papers to assess their quality, in respect of their chosen methods. Jeppsonââ¬â¢s paper, in a my opinion is a well designed study. The aim is suited to qualitative methodology. Assessing the quality of the study as proved challenging as its requires a different set of criteria, from quantitative research (table 1), And Patton (2002), outlines a series of considerations to establish rigor for qualitative research (table 2 ). The use of one interviewer, sample containing severe bulimics (Anorexia?), may have influenced the themes and results?à Also some ââ¬Ëreporting issuesââ¬Ëà concerning method etc,, canà all factors effecting quality.

It, however, suffers from a number of serious flaws, undermining its validity and effects when assessed to by RCT quality criteria (Greenhalgh T.,2006). Firstly, the study fails to provide a power calculation. For to detect differences betweenà theà three intervention groups using randomisation, it is considered that the study should be ââ¬Ëpoweredââ¬â¢ i.e contain enough patients to determine statistical accuracy. Normally 80% is considered the minimum standard of accuracy for clinical trails. (Ellis, Paul D, 2010), and leaves it open to type 2 errors.[10] This was not assisted by the attrition rate, especially at follow up. It contributed to the study being significantly ââ¬Ëunderpoweredââ¬â¢, so much so that the resultsà at one year follow-up à being ofà poor quality, the results could be dismissed[11] (Table 3 provides a critical evaluation) Table 3. Critical evaluation of quantitative study. Question Study: Jacobi et al. (2002) Cognitive-behavioural, Fluoxetine and Combined Treatment for Bulimia Nervosa: Short and long term results Does the study address the focussed question? Yes Were the patients randomly selected from a defined population? Patients were selected/recruited by advertisement and referral to the Psychology dept. Of Hamburg University. All had met the diagnostic criteria for BN. Was the assignment of patients to the intervention and control group randomised? There was no control group. Study compared effects of three different treatment conditions. Paper states they were randomised, but does not say how and by what method Were the participants and observers both blinded? Not stated though this difficult to achieve within psychotherapy trials Aside from the intervention were the groups treated equally? Yes Was a follow up completed Yes- at I year Did the study have adequate power to see an effect if there was one? No, there was no power calculation provided though this is common in psychotherapy intervention trials/studies. Very high attrition rate at follow up. Were all the patients who entered the trial properly accounted for? Full disclosure is given about the dropouts, calculations were made that suggest that the results atà follow up lack validity Were the results of the trial presented in a manner that allowed for full examination? No: adequate data was presented on tests MANOVA/ANOVA.à Ciââ¬â¢s not reported Secondly, the randomization procedure which gives the randomized controlled trial its strength. The investigators did not provide details of the randomization methods its used for the study[12], although this may be attributable to poor reporting, its is a significant emission (Jadad, 1998). The paper whilst providing a range of data, omits to report confidence intervals (CI)[13] for the three conditions and its results, and their were noà proposed effect sizes included the aims/hypotheses. Discussion Both studies addressed their research using different methods. Both were appropriate for the investigation, illustrating that methodology needs to be tailored toà the aim/hypotheses of the question under investigation. The Jeppson study was well designed, and managed to explore its research aim sufficiently, so some its findings had generalisability in treatment settings, and would benefit the CBT practitioner working with BN and aid ââ¬Ëtherapeutic allianceââ¬â¢ by taking into account its findings. By increasing understanding of how the processes have functions for the individual, well beyond the ââ¬Ëbehaviourââ¬â¢ itself. Jacobiââ¬â¢s study, although ambitious with a good design in principle, was seriously flawed. The under-powering of the study, the absence of good reporting on a number of methods and data, leave the study flawed. Its hypothesis and aims were suited to the methodology, but its sample size and attrition rate madeà generalizability of the results difficult. It did provide some evidence (weak), that CBT is efficacious for the treatment of BN, which continues in clinical practice. Word Count:à 3489 References à American Psychiatric Association (1994).

Television - Essay Example The CBC had been charged with setting up a public service television system following the study carried out by a wide-ranging royal commission on the arts, letters and sciences, which reported in 1951. As the twenties came to a close, Canadian political elite became increasingly concerned that the commercial messages and entertainment-driven values from American radio stations that freely drifted across the border were eroding Canadian culture. The most popular radio show in Canada was the American produced situation comedy Amos n' Andy. In 1929 the Liberal government of Mackenzie King commissioned three men to study and report on the state of broadcasting in the country, beginning a relationship between the state and the media that has not weakened since. The three were Sir John Aird, a banker, Charles Bowman, a journalist with the Ottawa Citizen, and Augustin Frigon, an engineer at L'Ecole Polytechnique in Montral. The commissioners studied virtually every form of radio broadcasting in existence during the year of the investigation. By the time Aird delivered his report, the Liberals were out of office and a new Conservative Prime Minister, R. B. Bennett was in control. It was up to Bennett to decide which form broadcasting would take in Canada. Like King, Bennett was deeply concerned that American influence, especially its views on liberalism and republicanism, would soon dominate Canadian thinking.

Biology - Essay Example The idea of an island in the science of biology and evolution advances the idea of species evolutionary patterns. While the arguments have been made and supported for the use of fossils, and for the use of various short lived species of creatures there is still the variations of species in some areas versus others. Dawkins readily admits that he has no idea where the initial split occurred for species, however, he further clarifies by stating that given the common genetic heritage and the proliferation of biological islands separations and splits in various species is only a matter of time. Speciation is the term used by biologists to define the splitting of a species into daughter species. Creationists have adopted the idea of speciation to explain the variances that are obvious with the use of a small boat and the idea that two of every kind of animal was aboard. According to Carl Wieland of Creation.Com, ââ¬Å"Virtually all creation theorists assume that Noah did not have with hi m pairs of dingoes, wolves and coyotes, for example, but a pair of creatures which were ancestral to all these species, and probably to a number of other present-day species representative of the ââ¬Ëdog kindââ¬â¢.â⬠(Wieland) Unfortunately, creationists still rely on a much shorter time period which cannot explain the lengths of time needed for each major shift and even for the minor shifts in various dog breeds and canine sub species.

This area of knowledge acquired can really lead to the achievement of my personal goal to improve my knowledge in pathology. This is because as noted by the authors, the principles and management of pneumothrax form an important basis in the overall pathological pathway to radiography. 18- 20/09/2013: I read ââ¬ËAsthma and COPDââ¬â¢ and I acquired a lot of information about these diseases and how they effect the lung. I also learned how can I provide the management of radiographic procedure and good quality images for patient with one of these diseases. After reading this book, my knowledge about Asthma and COPD is improving. I however think that this area alone cannot be an end in itself but a means to an end. This means that I need to expand my knowledge in other areas of radiography pathology in order to make the achievement of my personal goal realistic. The reason for this assertion is that the authors noted that asthma and COPD do not form part of the most reported cases and incidence that radiographers have to deal with. In effect, to have a full understanding of the pathology requires adding some more knowledge areas. 23 ââ¬â 26/09/2013: I read ââ¬ËDiagnosis and Management of Bowel Diseaseââ¬â¢. From this, I acquired so much information about various bowel disease such as diarrhea, consitaption, irritable bowel syndrome and inflammatory bowel disease. This learning improved my knowledge of the bowel disease and helped me to improve the management of abdomen radiographic procedure due to patient condition and provide good quality images. The authors from whom I learnt this have noted that abdominal radiography is a very complex process that requires a lot of expanded knowledge base on the part of the radiographer. This means that there is shared responsibility for me to know much more about bowel diseases and

Effect of Light Intensity on Photosynthesis
Effect of Light Intensity on Photosynthesis Plants occur around the world in a wide variety of environments. Plants are able to adapt to their surroundings because of photosynthesis. What affects the rate of photosynthesis? First, one must be able to identify what photosynthesis is. Photosynthesis is processing light. The formula for photosynthesis is 6H2O + 6CO2 à ¯Ãâà C6 H12O 6 + 6O 2. This ultimately means that water and carbon dioxide produce sugar as the plants energy, then the plant releases oxygen and water stays in the roots of the plant. Photosynthesis takes place in the chloroplast and chlorophyll will not absorb green light, therefore, while all the colors like violet, indigo, blue, yellow, orange, and red are being absorbed by the tree, green is being reflected that being the reason why plants are green. Proposed Explanation Different shades of light affect the rate of photosynthesis. The dependent variable for this hypothesis was the plants that we used. The independent variable was the different shades of light which were green, blue, and yellow. We placed each plant under each shade of light to get more accurate results. The control was just the normal experiment where we placed each plant under the light without any shade of light. We chose this experiment because plants do not absorb green light, they reflect it. So we figured different shades of light would have a direct affect on the rate of photosynthesis. Fertilizer has a direct effect on the rate of photosynthesis. The dependent variable for this hypothesis were different plants from experiment one. The independent variables were the different amounts of fertilizer we added to each plant. The control for this experiment was testing each plant without any fertilizer. After we tested the control, we added 100mL, then 105mL, then 110mL to each pla nt after each test. We chose to test the affects has fertilizer on photosynthesis, because fertilizer helps plants grow, therefore we believe photosynthesis would take place at a faster pace. Baking soda has an effect on the rate of photosynthesis. The dependent variable for this experiment was three different plants than the ones used in experiment two. The independent variables were the amounts of baking soda added to each plant. The control for this experiment was testing each plant without any baking soda. Then we put one pinch in each plant then tested it, then we added another pinch to each plant and tested it, then we added another pinch to each plant for a total of three pinches to complete our experiment. We chose to test the affects baking soda has on photosynthesis because if we add baking soda it will make carbon dioxide which ultimately allows the rate of photosynthesis to increase. Predicted Results The majority of our experiments that we were going to conduct we felt we would have a pretty common sense idea of the outcomes. Here since we are testing the amount of oxygen produced in our three different hypothesis, we will first try the different shades of light, different amounts of fertilizers, and if the amount of baking soda has anything to do with the plants photosynthesis. Our first hypothesis was the different shades of light would affect the amount of oxygen produced by the plants submerged in the water. First we would do our controlled experiment of no light shade. Here we would predict that the plant would absorb some of the colors which in return would produce an average amount of oxygen. We predicted that if the shade of light shined on the plant was green then the outcome of the oxygen produced would be fairly low since plants tend to reflect green light away from them. After we would test the green light we would move onto the yellow light. Here we predicted that the plant would produce a nice amount of oxygen since the plant absorbs multiple colors besides green and relatively absorbs yellow more since the majority of light given off the sun is yellow. Next we would try the blue light. We felt that since the light was going to be blue that the oxygen produced would be fairly low because the light absorbed from the plants tends to be higher in the yellow and orange areas. The next set of predicted results would be if the amount of fertilizer added to the plants would affect the amount of oxygen given off. Since fertilizers are used to help plants grow and photosynthesize we felt that maybe fertilizer will also increase the amount of oxygen created. We felt that the more fertilizer that was added then the more oxygen would be produced. First we will do our control of no fertilizer added. Here again we feel that the plant would just give off a normal or average amount of oxygen off. If we added 100 ml of fertilizers to the plants we predicted that a low amount of oxygen would be given off. Only because we predicted that a higher amount of fertilizer would increase the amount of oxygen. Next we would give an extra 50 ml of fertilizer to the plants. Since more fertilizer was added again we predicted that an increase of oxygen would occur. Finally an additional 50 ml of fertilizer was added. Here since that is 200 ml we predicted that the amount of oxygen given off would at least be doubled from the 100 ml that was added earlier meaning that this should be a higher amount of oxygen produce overall. Lastly we would predict the baking soda amounts and the oxygen produced. The reason we chose to test the baking soda is because if introduced to the water near the plant this would increase the amount of carbon dioxide absorbed from the plant. The more carbon dioxide absorbed, the more bubbles created by the plant. This would be our weakest hypothesis because we feel that the amount of carbon dioxide received would not really reflect the amount of oxygen produced because our original instinct was that it would have to do with light absorption. First we would test the controlled experiment of having no baking soda added at all. Once again our predicted result would be that an average or normal amount of oxygen would be produced. Next we would try adding a pinch of the baking soda to the water where the plant is. Here we would predict that little or no change would occur to the plant oxygen production. Actual Results After completing our multiple tests, we found that the majority of our predicted results were actually correct. After doing the control experiment, we realized without having anything enhance the plants that there was an average of 11 to 13 bubbles produced within a minutes span. Our first hypothesis, different shades of light, was what we really felt strong about and also was the one we felt would prevail to be the best supported. And that is was. Since plants have a higher preference to absorb yellow light we predicted that it would produce the most oxygen under the yellow film. That it did, the yellow produced the most oxygen bubbles out of all the different shades of light. The different films in general produced the most oxygen bubbles. Our third trial that we did seemed to produce an unusual amount compared to the rest. Underneath the yellow film in one minute it produced 79 oxygen bubbles. This was inconsistent with the rest of our results. Next we did the second hypothesis wh ich was fertilizer effected the amount of oxygen produced. Earlier explained, fertilizer is used to increase the rate at which plants photosynthesize by providing the nutrients needed. The plants really were not affected at all from the fertilizer producing an average amount equal to the control. The average was at 13 bubbles a minute and was the same throughout all three trials. Our third hypothesis, carbon dioxide effects the amount of oxygen produced was also at a low average of 11 to 13 bubbles a minute. This experiment really held no inconsistencies as well. All together we felt that the different shades of light had to do a lot with the amount of oxygen produced and now we feel this hypothesis was supported through the amount of oxygen bubbles that were produced. Here we have a graph that shows the average amount of bubbles that were produced in each trial(s). Conclusion The first of our hypotheses we tested for was that different shades of light affect the rate of photosynthesis. Based on our experimental results our data supported our first hypothesis, because for all of the different light shades we used in our experiment each of the plants for the most part produced either more or less oxygen bubbles than the control, supporting that light shades do in fact effect the rate of photosynthesis. Our data showed that plants tend to photosynthesize at the fastest rate in yellow light than anything else as they produced the most amount of oxygen bubbles in the amount of time. The test results could easily be reproduced to produce the same results if the given materials were the same and more trials were to be done with more plants to make sure that the experiment was not a fluke. The first possible margin for error in these tests is the size, and condition of the plant. This causes a problem, as the plants could be larger possibly absorbing more carbon dioxide, which means more oxygen bubbles would be produced. The plant also could be less fresh possibly producing less oxygen. The second margin for error is the type of light, which in turn would affect possibly the heat of the water maybe having an effect on the photosynthesis rate. The last margin for error is miscalculating the time on either the preparation period, or the observed time allowing for more bubbles to be produced. The addition of fertilizer effects the rate of photosynthesis was our second hypothesis, this hypothesis was not supported by our hypothesis, because the results were so varied that it was nearly impossible to tell whether the addition of fertilizer affected the rate of photosynthesis in any way. The reason that we have came to this conclusion was because though at 100ml each of the plants produced a lower oxygen amount when we tested for the 110ml the results were near identical to the control, meaning that fertilizer did not affect the rate of photosynthesis. This is a simple experiment to conduct and could easily be repeated for the same results, given that our procedure was executed as it shouldve been. The results could also be because we added the fertilizer in a large amount then added only small 5ml amounts for the other two trials which might not have made much of a difference. A better way to conduct this wouldve been to start by adding 50ml of the fertilizer, then 100ml then 150ml, which have a greater difference between them than 5ml intervals, so if the fertilizer was to make a difference it would become more apparent at which level the fertilizer caused the plants to demonstrate that change in photosynthesis rate. Another could be possible incorrect measurement of the fertilizer into the plants, which would provide one or more, more or less fertilizer than the other plants, corrupting the experiment. This causes a problem because it would make it so that different levels of fertilizer concentrations were in each of the plants, giving each a different level of nutrients. The plants too may not have had enough time to fully absorb the fertilizer into their roots, making it s o that there would appear to be no change in the rate at which each plant photosynthesizes. The last hypothesis we tested for was that the addition of baking soda to the plants water would affect the rate of photosynthesis. This hypothesis was supported, because the plants produced more bubbles when carbon dioxide was added to the water than the control which contained none. Our research showed that adding baking soda in fact did increase the rate of photosynthesis, because through the control all of the plants did not produce more than 3 oxygen bubbles, but when baking soda was added the plants created more oxygen, thus supporting that adding baking soda to the plants would affect their photosynthesis rate. The experiment could be recreated for the same results, given that the person recreating it has a tool that measures in pinches. The margins for error for this experiment include: inaccurate measurements of baking soda per plant, possibly not enough time to let the baking soda absorb into the plant, and how well the baking soda was distributed within the water. Inaccurate measurements or baking soda would have produced different amounts of carbon dioxide amongst each of the plants producing different oxygen levels. The baking soda might not have received enough time to absorb into the plant on the tests with larger amounts, thus making it appear that the amount of baking soda is for the most part irrelevant, just so long as there is some in there. The distribution of the baking soda within the water could also have been a place for error, as there is a possibility that the baking soda did not get evenly distributed throughout the plant thus making the water have different levels of concentration of carbon dioxide, because there could be clumps of baking soda sitting their preventing a quick, complete diffusion of the carbon dioxide molecules. Effect of light intensity on photosynthesis Effect of light intensity on photosynthesis Plants which obtain energy from sunlight and carbon dioxide to make carbohydrates are the process called photosynthesis. Then plants will take carbon dioxide from the atmosphere, add some water and use the energy of sunlight to form sugar.à The overall equation can be summarized as below: 6CO2 + 6H2Oà à à C6H12O6 + 6O2 In biology, the requirements for photosynthesis are chlorophyll, carbon dioxide, light and water. In fact, most of photosynthesis occurs in the chloroplast, Chlorophyll absorbs sunlight then converted to chemical energy during the process of photosynthesis.(Campbell 2008) There are two stages for photosynthesis. They are light reaction and dark reaction. Firstly, light energy splits water into oxygen and hydrogen during the light reaction. Then NADP and hydrogen add together and form NADPH2.After that, oxygen atoms join each other and form O2, at this time it released in the atmosphere.(Bailey 1997) Moreover, light energy generates ATP from ADP. The light reaction can also be summarized as below: 2H2O + NADP + ADP + P sunlight O2 + NADPH2+ ATP Chlorophyll Hydrogen is transferred into dark reaction. Then oxygen is released. It only occurs in the presence of light. Therefore, NADPH2, O2 and ATP are the products of light reaction. Secondly, carbon fixation occurs in the dark reaction has shown as below: ATP + NADPH2 + CO2 > ADP + P + NADP + glucose Enzyme use NADPH2 and ATP as the energy to convert to carbon dioxide. And carbon dioxide is absorbed from the atmosphere in dark reaction.(Bailey 1997) And then CO2 is converted into carbohydrates such as glucose. The concentration of water, carbon dioxide, the temperature and the light intensity are the most common environmental factors to affect photosynthesis (Lincoln 2010). So the aim of this scientific experiment is to investigate the effects of light intensity on the rate of photosynthesis. Methods_____________________________________________________________ Kept all the beakers and test tubes to be used on ice.Stalks are removed from leaves and leaves are ground in 200mL solution of buffer A.Buffer A was a mixture of potassium dihydrogen orthophosphate 10mM,disodium hydrogen orthophosphate 10mM and magnesium chloride 5mM. Then the extract is poured through the two layers of muslin into a beaker and suspension is also poured through eight layers of muslin into other beaker. The centrifuge spun the suspension at full speed in one minute. Then suspension is poured off and green chhloroplast is produced in total of 15mL solution of buffer C and it stored in ice for use.Buffer C was a solution same to buffer A but without magnesium chloride. Used the different pipettes to perpare the solution of buffer B at 6.7mL and 0.2mL chloroplast solution into a test tube.Mixed each solution well.Zero the spectrophotometer using 1.0mL of mixture at absorbance wavelength of 590nm.The spectrophotometer is used to measure how much light that the mixture absorbed. Used the different pipettes to prepare the solution of buffer B at 6.7mL, 0.2mL of chloroplast solution and 0.1mL of the dye into another test tube. Mixed each solution well and put it into the cuvette.The cuvette was placed at 0.3m for 60s from the lamp and the optical density of 1.0mL of this solution was measured with the spectrophotometer. All readings noted in the table and the optical density of solution was measured again. Repeated the same process at 0.5m, 0.7m,0.9m,1.0m from the lamp and each distance had a new mixture. The chloropast solution should kept in ice in this experiment to make sure that the solutions did not have any reaction until they placed under the light. Recorded the optical density at 590nm in each different distance from the lamp. Results______________________________________________________________ Rate of dye reduction Distance from light intensity (m) The graph shows that the distance from light intensity are increased when the rate of dye reduction decrease between 0.3m to 1.1m. That mean the rate of photosynthesis also decreases in this graph. The maximum rate of dye reduction is 0.398 at 0.3m from the light and the minimum rate of dye reduction is 0.045 ate 1.1m from the light. According to the data of the above graph, Q1=0.065, Q3= 0.345 and IQR =0.28. The lowest rate of dye reduction is 0.065-1.5 x 0.28 = -0.355. In this case the lowest rate of dye reduction from the data lies above -0.355, so there is no outlier. On the other hand, the upper rate dye reduction is 0.345+1.5 x 0.28 = 0.765.Hence there is no outlier also. The data are positively skewed distribution because the data trend from the left to the right. Discussion____________________________________________________________ During the photosynthesis, the light intensity will increase when the rate of photosynthesis increase.(Pang 2006) In my result, the distances from light intensity are increased when the rate of photosynthesis decreases, which mean when the light intensity decrease, the rate of photosynthesis also decreases. In this case, my result is true. There are some experimental errors in this experiment. It is hard for us to make sure the chloroplast solution will not active until they were placed under the lamp because there were the other light from the surrounding in the room such as neighbour lamps. So the experiment should be done in a dark room that can reduce the effect of the light and the result will become more accurate .Also, more cuvette should be provided because it will effect the result if some of cuvette was not clean well. Moreover, there are some limitations in this experiment. Different solution should be used different pipette to prevent the other solution will add on the result.Also, meaured the volume of each solution that can help to reduce variations.Furthermore, placed the test tube of chloroplasts in the ice because this can ensures the temperature of the test tube is not affected by the heat realeased from the lamp. As temperature might affect the enzyme activity of the plant and hence the rate of photosynthesis. Light is needed for photosynthesis in plants. When chloroplasts in the leafs cell are facing to light,they form ATP from ADP. Oxygen is produced during the photosynthesis. (Campbell 2008) According to my result, light energy increases when more water molecules are split into oxygen. At this time, the light reaction occurs faster and more ATP and NADPH2 are produced.Therefore, it will have more sugar and oxygen formed in dark reaction.In this case thre rate of photosynthesis increases.
