The X - ray was discovered in 1985 by a German physicist, Sir W. C. Roentgen. Since then, the application of radiation has been widely used in radiology, nuclear medicine and radiotherapy for both diagnostic and treatment of different kind of diseases encountered by the human beings.(Luk, Leung, & Cheng, 2010).Even though the radiation play important role in diagnostic and treating the patient, the biological effect caused by medical radiation is more concerned in recent survey(Arslanoğlu et al., 2007). Due to the advanced development of medical equipment’s such as multi - detector row computed tomography and nuclear medicine there is significant increase in the population’s cumulative exposure(Rehani & Berris, 2012).The application of computer tomography has increased dramatically since 1970,with the number of annual scan go up to 72 million in 2007 form 2 million in 1980s (Baumann et al., 2011).The radiological examination performed every year crossed 3.6 bill ion and the number is expected to increase in future(Nations, Committee, & Radiation, 2010).since the radiological exam...

Psychology and Christianity Essay

An integrative approaches to Psychology and Christianity by David Entwistle explains the fundamental question whether Christians can take a place in psychology. By marrying both scientific and theological disciplines, the author takes a stand to argue that psychology and Christianity can help an individual to serve the Lord within the parameters of duty to love. In this book, Entwistle gives a concise understanding for the interplay between theology and science by taking us through the historical analysis of psychology and how it explains how individuals have their characteristics, qualities and talents which help them serve God and society (p 35-37). Arguably, a person cannot be an effective psychologist without the basis of what is right with is captured in Christianity as a moral concept. With regard to these, our society is shaped by history as well as environment. The knowledge we acquire throughout our existence is inspired by our past experiences. Significantly, Christianity has facilitated how we structure our mindsets over various moral issues in the society. To bridge the gap between Christianity and psychology, Entwistle argues that there are five important paradigms that show the interplay between theology and psychology. This includes spies, enemies, neutral parties, colonialists as well as allies as elements serving ones master called sovereign (p39). The argument presented by Entwistle articulates the concept that psychology resembles theology in line with goals and serve fundamental human purposes of improving as well as giving meaning to the life of a human being. The two disciplines revolves around human functioning and nature hereby, an integrative approach to psychology and Christianity underscores that when it comes to dealing with human life and truth, there should be a unified approach that uses both secular and sacred elements of thinking. With regard to these, both psychology and Christianity need to be integrated because life at large revolves around helping others with issues that promote quality lives and harmony in the society. Critical and Concrete Responses After reading an integrated Approach to Psychology and Christianity, I was led to thinking that the understanding of God and psychology relates coherently to the Maslow’s Hierarchy of Needs. I agree with the argument because my experiences in the past have acquired as a result of my environment and needs as a human being which moves closer to the relevance of psychology in the life of human beings. Similarly, the feeling of self-actualization is realized through a Christian’s association with God through divine moment of prayer, fellowship and engagement in charitable works because the Bible stipulates that such gestures will grant one an eternal life. On the same note, psychology understands that self actualization is a need that must be met after all the other seven basics ones have been met. Entwistle asserts that both eternal life and Maslow’s hierarchy of needs portend single ideas of achieving in life and feeling the sense of achievement. The truth revealed in the word of God and the various works of Jesus Christ as well as the Christian ministry is something that is characterized in my life. Arguably, life revolves around all these and it is somehow impossible to separate it from life in a Christian perspective. Equally, my life experiences have led me to conclude that certain things in life should be done in my own way. Accordingly, there are many times I have learnt from my experience and have faced many consequences as a result of my choices. In view of this, Entwistle asserts that doing things the way we want articulate the psychological belief of emotions, socialization, intelligence and human needs. However, this argument raises the question of conflicting forces between our beliefs and human desires. As Christianity stipulates how we should behave in line with morality, psychology justifies why we must attend to our human desires. As such, an integration approach to life should cover both Christian teachings and the sentiments echoed by psychologists (pg 59-63). I was a temperamental person who for years reprimanded people for wronging me. Although I justified my case by arguing that I respect my feelings and that is me, God called upon me to change my temperament by managing anger so that I can accommodate others. God’s intervention in this case harmonized how I lead my life because; I was able to strike a balance between my religious beliefs and human desires. Most significantly, managing a balance, or rather moving my hot tempers to reasonable levels necessitated the intervention of counseling services. Accordingly, I embarked on regular counseling with gave me an insight on how to understand other and tune my emotions to the levels that accommodate others feelings. This way, the book an integrated approach to psychology and Christianity, underscores the importance o integrate theology and psychology. Somehow, psychology helps Christians to understand their human face and through services such as psychotherapy, counseling, a Christian will be able to moderate the psyche of the soul as well as the soul of psychology. Personal Reflection Although Entwistle advocates for s linkage in the two disciplines and goes ahead to propose that Christians should integrate science theology in viewing issues of life, it becomes critical to the Christians because one question that is raised is how can Christians be motivated to use psychotherapy and counseling services as a way of integrating psychology and Christianity. Entwistle asserts that moral concepts of live are well explained in Christian doctrines and through psychology, such moral doctrines can be well explained and a Christian will consciously understand the essence of being a Christian. However, the book fails to recommend how counseling can be promoted and how psychotherapy and other psychological services can be enshrined in the Christian education. Accordingly, the question of how we as Christians should accomplish the goal of promoting the integration of science to theology takes the center stage of the entire debate that Entwistle engages in concerning reaping the full benefits of integrating psychology and Christianity. Arguably, Entwistle uses words that further complicate the message of integrative approach to psychology and Christianity. In essence, this makes it difficult for an average reader to appreciate the information being conveyed let alone retention. In addition, it plausible to note that as a reader I found it hard to grasp the interests as well as concept of integrating psychology and Christianity because of the fact that the book is written broad view hence it seems to argue in circles around the importance of using both psychology and Christians teaching. Recommended Action Owing to this weakness of language and jumping around ideas, there are measures that can be taken to help us benefit from the Christian psychological integration. Advising others on how to benefit from counseling will form the fundamental action that spearhead the campaign for integrating Christianity and psychology. In this view, sharing some of my experiences with regard to how I have benefited from counseling to succeed in my Christian faith and life at large will work in helping in the whole initiative of promoting such kind of integration. If possible, all counselors who happen to be Christians should uses their positions to root the belief of integrating Christianity and psychology into other Christians and equally work with other counselors to devise methods of overcoming challenges that may come with their initiatives. At the same time, the basis of my intervention will revolve around moral maturity. As such, it is recommended that encourage Christians to search for the truth and thus understand for themselves how best they can use psychology to succeed in their lives and Christian works. In a nutshell, Entwistle espouses that it is only through a concise integration of both science and theology that Christians will embrace the concept of togetherness. In other words, they will understand how humans functions and thus structure their spiritual beliefs in a realist way to avoid the self conflict that is always inherent among many believers. Psychology signifies the many teachings that are typical to Christianity such as values. Reference Entwistle, D. (2004). Integrative Approaches to Psychology and Christian.

To what extent has the traditional male role changed in the last 20 years?

The customary role of the male in relation to the home as being the head of the household, the protector and the provider is slowly eroding. The male’s duty was unquestionably embodied in these three ideas until the 1970’s. The growing feminist movement began to question and displace these roles as solely belonging to men The traditional male role has seen significant changes in the family unit, society and personally.In the past men were the sole breadwinners and they were left with the task of bringing home the money. It was their job to be financially sound so as to take care of their family’s needs. Being the sole breadwinner, it was the men who made all the major decisions in the home. Women on the other hand were left with the daunting task of being homemakers and taking care of the chores and looking after the children.I remember my grandmother talk about her father and how everyone in the house including her mother used to be as quiet as mice when their f ather came home as they were told not make any noise or the unthinkable would happen. Nowadays, it is just the opposite. The roles of both husband and wife have changed. Both the husband and the wife work to make ends meet. Most households cannot sustain themselves on just one salary.As both the man and the woman are out earning a living, it is only natural that household chores and child rearing has to be shared. Another area that has seen change is indecision making. While in the past it was the man who made all the decisions about the family, now it is collaborative decision making.Most women are equally educated as men and are able to sit and discuss on an equal footing with their spouse on methods of childrearing and even other major family decisions. There has also been change in the role of man in society. In the past, men have always held prominent positions in the workplace. They were the ones who made the decisions on how to run their companies.Women held minor positions s uch as clerks, stenographers and secretaries, while men were given positions such as directors, managers and CEO’s. You could see men working in corporate, financial, legal and political fields, Men held the full authority to run a family and the country from bottom to top.Now this is changing with many women breaking through the glass ceiling and taking on more powerful and significant functions in different aspects. With  education, women have been able to rise to greater heights. We have women who are CEO’s politicians and even Prime Ministers and Presidents of countries.Lastly, men from time immemorial have been pictured as being strong, fearless and successful. They have always been conditioned to not show any kind of emotions that could damage their role model image. Men were told that they should not cry and should always have a very stern character.Fathers were unapproachable and did not take an active part in their children’s emotional growth. This wa s left to the mother. But this is now changing. Men are moving away from being strong, silent and unfeeling. They are starting to express their feelings and taking on a more soft and thoughtful personality.In conclusion, it must be stated that the changes in the role of the male species is here to stay and must be respected within the structure of the family unit, society and as an individual. In my opinion, I think I would like to see the world judged based on humanity rather than prejudged roles.

Coulumbs Law Lab Report Essays

Coulumbs Law Lab Report Essays Coulumbs Law Lab Report Paper Coulumbs Law Lab Report Paper This relationship is described by the following equation: Equation 1: In this equation, and are the charges on point charges 1 and 2 and r is the distance between the two charges. The direction of the force in this special case is always along a straight line drawn between the two charges. Additionally, it is important to note that charge is conserved; it can be moved but cannot be created or destroyed. Specifically, in this lab, we will move the charges around to setup a test of Coulombs law on a simple electroscope. As mentioned above, he experiment will be split into two parts, first measuring the force as a function of distance and then we will look at how the magnitude and sign of the charges affects the force. Lastly, we will use Equation 1 above to determine the amount of charge (in Coulombs) that we can generate with static electricity. 3. Experimental Setup The apparatus used in this experiment included: an electroscope chamber with suspended sphere and top cover, 2 guide blocks with spheres, cotton and wool squares, plastic rods, and a white vinyl strip. It is crudely drawn below. Figure 1 Electroscope Setup 4. Reoccurred Part 1 Charging a Sphere 1. Began by removing the right side guide block and setting it aside. 2. Inductively charged the sphere attached to the left side guide block by doing the following: a. Rubbed the wool square on the vinyl strip to transfer charge to the strip b. Brought the sphere on the guide block near to the charged strip but do not touch them together. Wi th the sphere close to the strip, I touched the sphere with my finger and then removed my finger. C. After the finger was removed from the sphere, I pulled the sphere away from the charged strip. The sphere on the guide block was then charged. Recharged the sphere again for the next part 4. Slowly slid the guide block with the charged sphere into the left side of the chamber and carefully observed the two spheres as they approached each other and just before they touch. Recorded observations. Part 2 Dependence of Force on Distance 1 . Now we wanted to add charge to the suspended sphere by charging our guide block sphere as before and then sliding it into the chamber until the two spheres touch. 2. When the two spheres touch, the charge becomes equally distributed among them. We repeated this charge transfer and kept increasing the charge n the suspended sphere. Repeated this charging process until we had sufficient repulsive force to cause a separation of at least 1 CM to 2 CM. 3. Measured the displacement of the suspended sphere from equilibrium d for several different separation distances r. Took 5 different data points spread out over as wide a range as possible. Part 3 Dependence of Force on Charge 1 . Recharge the spheres, and after the two spheres have shared their charge, position the left guide block sphere such that you have a large displacement. Record the separation of the two charges r and the distance d. This is the first ATA point 2. Reduced the charge on the left guide sphere by half. To do this, grab the unused right guide block sphere and ground it using your finger, then remove your finger and touch the two spheres together. They now each have half the initial charge. 3. Now reposition the left guide guide block sphere to the previous value of r and record the new value of d. 4. Repeat this process two more times with 1/4 and 1/8 the original charge. 5. Experimental Results Part 2 Fee Calculation: Graph 1 Force vs Sphere Separation Graph 2- Force vs 1/raw Graph 3 Log of Force vs Log of 1/raw Part 3 Graph 4- Fee/Of vs Q/q Charge calculation 6. Questions part 1. A. What would happen if in step 2-c, you remove the charged strip from the vicinity of the sphere before your remove your finger from the sphere? B. What we have just done is charging by induction. In your own words describe what is happening in panels a through e in figure 2. C. The gray spheres are Styrofoam with a conductive coating. Why do we need the spheres to be conducting? D. Does the suspended force experience a force? Can you explain why the suspended sphere would experience a force even though it has no net charge? Doesnt this contradict Coulombs Law which says that you need two charged objects to have a force? E. Notice in the left panel of figure 3 that the size of the spheres is important the unlike charges are much closer to the charged sphere than the like charges. What is the consequence of this? Part 2- a. Plot a graph of the force as a function of the separation of the two spheres. Comment on the general trend of the data: does it look as you would expect? Why or why not? B. Is the graph linear? What would a linear dependence between Fix and 1/raw tell you? What does the slope of this plot represent physically?

Hacienda Tabi - Plantation Archaeology Mexico

Hacienda Tabi - Plantation Archaeology Mexico Hacienda Tabi is a landed estate of colonial origin, located in the Puuc region of the Yucatn Peninsula of Mexico, about 80 kilometers (50 miles) south of Merida, and 20 km (12.5 mi) east of Kabah. Established as a cattle ranch by 1733, it evolved into a sugar plantation that encompassed more than 35,000 acres by the end of the 19th century. Approximately one-tenth of the old plantation now lies within a state-owned ecological reserve. Hacienda Tabi was one of several plantations that were owned by descendants of early Spanish colonists, and, like plantations of the same period in the United States, survived on the basis of near-slavery of native and immigrant laborers. Originally established in the early 18th century as a cattle station or estancia, by 1784 the propertys production had diversified enough to be deemed a hacienda. Production on the hacienda eventually included a sugar mill in a distillery for producing rum, farm fields for cotton, sugar, henequen, tobacco, maize, and domesticated pigs, cattle, chickens, and turkeys; all of this continued until the Mexican Revolution of 1914–15 abruptly ended the peonage system in Yucatn. Timeline of Hacienda Tabi 1500s - much of the Puuc region is part of the Xiu Maya dynasty1531 - Spanish military forces marched into the Yucatn1542 - city of Merida founded by Francisco de Montejo1547 - first Spanish mission founded at Oxkutzcab1550s - encomienda system established in the Puuc1698 - Juan del Castillo y Arrue petitions for a land grant named Tavi to be used as an encomienda1733 - Tabi established as the name of the parcel in the Santa Elena Valley1784 - Tabi designated a hacienda; its owner is Bernadino Del Castillo1815 - Tabi purchased by Francisco Calero y Calero; a land survey commissioned1821 - Mexico achieves independence from Spain1820s - first state laws supporting peonage (debt slavery) system1847 - Caste War (Resistance movement between Maya and Spanish descendants) breaks out1855 - Tabi bought by Felipe Peon1876 - 1911, Porfirio Diaz rules Mexico1880s - narrow gauge rail established in the Yucatn1890s - industrial sugar mill at Tabi1893 - Tabi bought by Eulogio Duarte Troncoso; exten sive renovation of principal buildings undertaken 1900 - Tabi encompasses 35,000 acres and 851 resident laborers1908 - Journalist John Kenneth Turner publishes articles describing slavery on haciendas in Yucatn.1913 - Tabi owned by Eduardo Bolio Rendon Maldonado1914 - Mexican revolution reaches Yucatn, peonage system abolished1915 - Hacienda Tabis village for laborers abandoned The center of the plantation included an area of approximately 300 x 375 m (1000x1200 ft) within a thick wall enclosure of limestone masonry, measuring 2 m (6 ft) high. Three main gates controlled access to the great yard or patio principal, and the largest and main entry frames the sanctuary, which held room for 500 persons. The major architecture within the enclosure included a large two-story plantation house or palacio, consisting of 24 rooms and 22,000 ft ² (~2000 m ²). The house, recently refurbished with long-range plans for the development of a museum, boasts classic architecture, including a double colonnade on the south face and neoclassical pediments on the upper and lower levels. Also within the enclosure was a sugar mill with three chimney stacks, livestock stables, and a sanctuary based on colonial Franciscan monastery architecture. A handful of traditional Maya residences are also located within the enclosure wall apparently reserved for upper-level servants. two small rooms in the lower West and the plantation house were set aside for jailing peasants who disobeyed orders. A small external structure, called the burro building, was, according to oral tradition, used for public punishment. Life as a Laborer Outside the walls was a small village where as many as 700 laborers (peons) lived. Laborers lived in traditional Maya houses consisting of one-room elliptical structures made of masonry, rubble stone, and/or perishable materials. The houses were placed in a regular grid pattern with six or seven houses sharing a residential block, and blocks aligned along straight streets and avenues. The interiors of each of the houses were split into two halves by a mat or screen. One-half was the cooking area including a hearth kitchen and foodstuffs in the second half with the storage bathing area where clothing, machetes, and other personal goods were kept. Hanging from the rafters were hammocks, used for sleeping. Archaeological investigations identified a definite class division within the community outside of the walls. Some of the workers lived in masonry houses that appear to have had preferential placement within the village settlement. These laborers had access to better grades of meat, as well as imported and exotic dry goods. Excavations of a small house inside the enclosure indicated similar access to luxury goods, albeit clearly still occupied by a servant and his family. Historical documentation indicates that life on the plantation for the workers was one of ongoing indebtedness, built into the system, essentially making slaves of the workers. Hacienda Tabi and Archaeology Hacienda Tabi was investigated between 1996 and 2010, under the auspices of the Yucatn Cultural Foundation, the State of Yucatns Secretary of Ecology, and Mexicos National Institute of Anthropology and History. The first four years of the archaeological project were directed by David Carlson of Texas AM University and his graduate students, Allan Meyers and Sam R. Sweitz. The last eleven years of field investigation and excavation were conducted under the direction of Meyers, now at Eckerd College in St. Petersburg, Florida.

360 Report of Guccio Gucci in China Coursework Example | Topics and Well Written Essays - 1500 words

360 Report of Guccio Gucci in China - Coursework Example These strategies include: advertising, craftsmanship, public relations, a touch of mythology, and word of mouth (Marketing Mentor, n.d.). In order to develop effective marketing campaing in China, it is vital to understand the luxry market in China and consumers’ behavior. The Chinese luxury market is huge and is projected to grow by 18% annually from 2010 to 2015, exceeding 20% of the global luxury market (GroupM and CIC 2011). Luxury buyers in China value the status they gain by wearing luxury goods. Chinese consumers like to show their off their shopping achievements and purchasing power. That is why sharing of shopping experience is common in the luxury segment (GroupM and CIC 2011). By developing a business expansion strategy in China, Gucci’s marketers have to focus on the top domestic markets by RMB 10 million-plus population. These cities inlcude: 1) Beijing, 2) Guangdong, 3) Shanghai, 4) Zhejiang, 5) Jiangsu, 6) Fujian, 7) Shandong, 8) Liaoning, 9) Sichuan, and 10) Henan (GroupM and CIC 2011). See the map below. Fast growing luxury market in China captures consumers with different motivations and behaviors. In order to develop effective marketing strategy for this Asian market, Gucci has to consider the purchase drivers common for Chinese luxury consumers. There are indentified four major segments of Chinese luxury consumers: aspirational buyers; quality pursuers; status seekers; trend setters (GroupM & CIC, 2011). Aspirational buyers are mainly white-collars and college students who are very sensitive to price and tend to purchase accessories of famous luxury brands. The purchase drivers include: brand awareness, style and design, and price (GroupM & CIC, 2011). For Qaulity pursuers quality and fine workmanship are the major criteria while purchasing the luxury brands. The purchase drivers include: quality, price, style and design (GroupM & CIC, 2011). The third category of Status seekers implies

Customer Service Management of Rogers Cable Inc of Canada Essay

Customer Service Management of Rogers Cable Inc of Canada - Essay Example The deregulation of the media and communication industry brought the major challenge before the monopolistic RCI. The Canadian Telecommunication Act of 1993 was governed by three principles; the universal service, fair treatment of the customers and interconnectivity of networks. This marked the arrival of a competitive market in the industry. There was a need for RCI to survive among the potential competitors like Bell Canada. As the customers of RCI will be thrown open to various options, there was an urgent need to retain them. Consequently the customer service of RCI was facing a severe test. Hence the company conducted a refined analysis in regard to its customer service. The analysis revealed the critical condition about RCI’s service issue. The analysis produced that there was a significant number of repeat service calls after the installation. An in-depth analysis conducted on a sample of 100 customers confirmed that 20% of them had a repeat work. After considering the historical data it was observed that 16% of the repeat works were done in the houses which had a new (within the previous 30 days) installation. This called for the need to revise the prevailing customer service system which threw light on the cause of such considerable repeat work. The prevailing system, which was followed by RCI in fixing the technical problems in households, involved outsourcing of service technicians. Since the demand for service technicians is seasonal, RCI opted for outsourcing.... The analysis revealed the critical condition about RCI's service issue. Cause of Poor Customer Service The analysis produced that there was a significant number of repeat service calls after the installation. An in-depth analysis conducted on a sample of 100 customers confirmed that 20% of them had a repeat work. After considering the historical data it was observed that 16% of the repeat works were done in the houses which had a new (within the previous 30 days) installation. This called for the need to revise the prevailing customer service system which threw light on the cause of such considerable repeat work. The prevailing system, which was followed by RCI in fixing the technical problems in households, involved outsourcing of service technicians. Since the demand for service technicians is seasonal, RCI opted for outsourcing. Among all the technicians only 18 % constituted RCI's cable employees. This caused a communication gap between the Cable technical Support area of RCI and the outsourced technicians. Due to this communication gap the technicians were unaware of the urgency of fixing the problem in the customer's house. The company lacked a central system that will connect the outsourced companies for technicians with RCI. While focusing on the outsourced technicians a major fault was noticed in their skill set and tools for problem fixing. The technicians were not educated about the new Roger products and didn't have sufficient technical tools to carry out a successful problem fixing. Solution to the Problem The company after analyzing the problem initiated a program across the organization named FTR (First Time Right). The objective of the program was to spread quality awareness about RCI. Trial The program was experimented over a team
