Leadership and Ethics - 1248 Words
Abstract Although managers need leadership qualities in order to effectively complete their tasks, it is imperative to understand the difference between a manager and a leader. Management is a function in which directives are carried out and executed during the day to day activities of the business, while leaders innovate, and bring forth ideas envisioned that many would discount as possibilities. A leader must understand their role and the effect they have on others. Failure to understand the extinct a leader has on his/her organization and the operations of the company may cause turbulence and discontent in their subordinates. When this understanding is breached, resistance, mistrust, and defiance receive an open invitation.

Leaders are the individuals who go beyond the status quo, their views are different, and they are less conservative and willing to take the necessary ri sks to achieve a goal. These key factors separate leaders from managers. Leaders are able to lead because people have belief in their capabilities and it inspires individuals to stretch themselves beyond their limits. Leaders are capable of selecting talent, coaching, motivating, and building trust (Maccoby, M., 2000). Is the CEO trying to lead or manage this change initiative? The CEO is managing the change initiative as opposed to leading it. Leaders are individuals who are visionaries and see the horizon and the long term effects of the decisions made. He has leadership qualities as managers should have, however, managementââ¬â¢s trust in his decisions is lacking. Leaders are noble for building relationships and motivating individuals to follow their lead, however, he is experiencing resistance due to the lack of trust and belief his subordinates have in his capabilities. In Organizing Genius(Addison-Wesley, 1997) Bennis and Patricia Ward Biederman point out that leaders of gr eat teams pick talent on the basis of excellence and ability to work with others.

Essentials of Total Quality Management - MyAssignmenthelp.com
Question: Discuss about the Essentials of Total Quality Management. Answer: Introduction: Total Quality Management is a system of managing quality aspects in the business through maintaining high standards in organizational activities and processes(Tzamalis, Panagiotakos, Drosinos, 2016). The present research study has been emphasizing on benefits of implementing the approach of Total Quality Management. Along with this, the discussion is also made of quality management concepts, principles, and tools which help the business entity to achieve numerous benefits. Furthermore, the researcher has also mentioned the steps which are required to implement total quality management approach in business activities. Hence, in the study, the overall management of total quality management is being stated in a detailed manner. Total Quality Management is an important approach to implement in Domino's Pizza because the requirements of customers are changing on greater extent. Since Domino's Pizza is the largest pizza chain; hence the business is required to emphasize on the needs and demands of customers. Quality holds an important place in business services; therefore to maintain the interest of customers, it is vital for Domino's to implement quality management approaches(Sallis, 2014). At present, Domino's have been experiencing numerous problems and challenges which is reducing business's capabilities and efficiency; therefore this is the reason implementation of TQM is essential. It is also useful to raise business standards through adopting quality measures. Apparently, with the help of TQM, Domino's will be able to strengthen its competitive position in external market place, and that can also assist the business to enhance customer base. Currently, every business focuses on attaining competitive advantage; however, for that several efforts are required to be laid on developing quality standards. With the help of TQM, Domino's will be able to adapt to changing and emerging market which will also encourage business services(Pineda, 2013). Productivity level of business can also be enhanced; therefore there are various benefits which Domino's can acquire through implementing approaches of TQM. The approach also directs the business to eliminate waste and defects from the process of production; henceforth it is quite useful regarding organizational development. The main targets of Domino's are youngsters and kids; thus the business has to focus on health aspects so that customer's requirements can be met. In addition to the same, processes and activities of Domino's can be streamlined as a proactive work system. Similarly, challenges and problems in work systems can also be eliminated through the application of TQM. It has been observed that quality management approaches help in reducing duplicate efforts; thus unproductive activities can be eradicated from business's practices. Along with this, regarding cost and time, other benefits can also be acquired through correct implementation of Total Quality Management(Obeidat, Hashem, Alansari, Tarhini, Al-Salti, 2016). Currently, many competitors have entered in pizza industry; therefore this is bringing huge challenges for Domino's. Thus, to retain the position in external market place, it is necessary for a business to readdress all the problems and to take necessary steps. In the realm of competitiveness, Domino's must comprehend the requirement of customer satisfaction. Total Quality Management typically aims to improve quality standards through identifying the best measures to meet expectations of customers. The interventions of TQM can assist Domino's to quantify problems to eradicate all such problems that affect business processes. For instance- customers usually desire for timely services; however waiting time changes the interest of customers(Oakland, 2014). With the implementation of quality management approaches, waiting time can be reduced through suitable scheduling and client handling processes. At the same time, the process of delivery can also be enhanced so that faster services can be provided to the customers. Organizational development is yet another benefit that can be acquired through TQM. It can also improve work culture by educating the employees towards quality development. The proactive work culture at Domino's can prevent mistakes; hence ultimately corrective measures can be implemented. In this area, Domino's can also implement Juran Quality Trilogy which comprises of three legislative processes such as quality planning, quality control, and quality improvement. Quality planning involves the development of awareness for improvement which also leads to attaining organizational goals. However, the management of Domino's needs to show greater commitment to planning for changes and accordingly it generates the need for training and development(Mok, Sparks, Kadampully, 2013). Furthermore, quality control is yet another process that develops the methods to test the products and services for quality dimensions. Therefore, the stage of testing eradicates deviation from business processes, and ultimately it leads to transformation and improvement. Afterwards, Domino's can seek for excellence and perfection through improving business standards. Domino's is also required to diagnose the problems on a constant basis so that suitable solutions can be developed accordingly. Here, it is clear that Domino's is required to pay attention to the implementation of Total Quality Management because of the above-mentioned benefits. However, prior implementing the approaches, it is imperative for Domino's to ensure that employees give their consent to adopt the changes. Apart from this, The Deming Cycle can also be adopted at Domino's for the purpose of analyzing the efficiency of components of business processes. The process can allow Domino's to measure the performance level and accordingly, decisions related to improvements can be taken. What quality management concepts, principles, and tools should be implemented within Domino's to achieve business benefits? The tools of quality are designed for the purpose of identifying issues related to quality. Since Total Quality Management approach is essential for Domino's; therefore it is also vital for the business to identify all the related issues. There are various tools that can be applied in the quality area such as a cause-and-effect diagram, check sheet, control chart, histogram, Pareto chart, scatter diagram and stratification(Mohammad Mosadeghrad, 2014). To showcase the benefits of total quality management, several principles should be implemented so that degree of benefits can be enhanced. Application of Fishbone chart will assist Domino's to identify causes for an effect or problem and accordingly it provides ideas for improvement. Typically, it is used to structure a brainstorming session; hence Domino's can acquire numerous benefits through its application. The tool includes methods, machines, people, material, measurement, and environment. This can aid Domino's to find manage business aspects and practices in an appropriate manner. It also shows causes of a specific event which analyzes the entire process of production and manufacturing. Ishikawa is useful regarding identifying the ways to prevent quality defect which causes an overall effect(Jurow Barnard, 2013). Hence, each cause or reason that leads to imperfection is typically a source of variation. Afterwards, causes are grouped into different categories which help in identifying the sources of variation. It includes a root-cause analysis which is intended to express the relationship between different variables. At the same time, it also provides additional insights into process behavior. Therefore, Domino's has to ascertain the causes through brainstorming session and by analysis. Further, it is grouped into different branches, and that also leads to restructuring the approach. Hence, in this context, Domino's has to emphasize on lean manufacturing to strengthen production system. This also requires focusing on 5Ms. Therefore, implementation of Fishbone diagram can assist Domino's to identify all the elements that have the greatest impact on business processes and practices. Moreover, this includes a grouping of causes which separates overall business process. To implement quality aspects in Domino's, it is essential to find out the problems so that overall business practices can be improved. According to the problem statement, suitable ideas can be implemented to reduce the effect of possible causes(Gould, 2013). Moreover, Domino's can also implement Pareto chart wherein significant factors are depicted on a bar graph. The lengths of the bar show frequency or cost and then they are arranged with longest bars on the left and shortest to the right. Therefore, in this way Pareto chart is useful for Domino's in depicting the situations which are highly significant for business success. Through this, the frequency of problems or causes in a process can be identified, and at the same time, it can ascertain all specific components of a service. However, at the same time, Domino's needs to decide the categories to group items(Gimenez-Espin, Jimnez-Jimnez, Martnez-Costa, 2013). Measurement is also appropriate so that significant factors can be determined that has a direct impact on business services. For instance- the chart will be useful for Domino's in analyzing the frequency of problems like customer complaints. In the chart, all the complaints are equally rated and accordingly specific solutions can be found out. The left vertical axis in the chart represents the frequency of occurrence; however, on the alternate side, it can also represent cost or any other significant unit of measure. Contrary to this, the right vertical axis shows the cumulative percentage of a total number of occurrences of a specific factor. Since the reasons are placed in decreasing order; the cumulative function is termed as a concave function(Gharakhani, Rahmati, Farrokhi, Farahmandian, 2013). Domino's can implement Pareto chart to highlight the most important aspect among a different set of factors. Moreover, in the process of quality control, it is highly useful in showing sources of defects in the entire process. Additionally, it also describes the highest occurrence of the defect along with the reasons for which the problem is being developed. For each of the bar in the Pareto analysis, it shows acceptance limi ts and how it produces problems and challenges. Apart from this, the approach of stratification can also be implemented through the combination of other data analysis tools. The meaning of data is not comprehensive when a variety of sources are lumped together to see the impact of problems. The technique is also useful in separating the data to see the patterns. Domino's can use this technique of stratification especially when data analysis may require separation of different sources and conditions. This can also strengthen the data collection process of Domino's in different product and service categories. How to implement TQM in the business The specific plan is required to be developed for the purpose of implementing TQM in Domino's. In this respect, the business can implement Deming's approach and Crosby's approach to quality improvement(Fu, Chou, Chen, Wang, 2013). Hence, in this respect, the manager is suggested to consider all the necessary points. Creation of constancy of purpose is vital to improve products and services. Hence, Domino's should consider the areas of improvements and accordingly new changes should be implemented in business courses. Afterwards, adoption of new philosophy is vital to improve the business situation of Domino's. Inspection and observation are termed as the only method through which quality prospects can be ascertained(Doeleman, Ten Have, Ahaus, 2014). However, at this stage, Domino's should cease its dependence on inspection to maintain quality. Price should not be the only method to judge the quality of business; however, Domino's should adopt new measures to minimize total cost through handling business activities in an appropriate manner. There should be a constant focus on improvement after planning about business development. Provision of training is also vital to make people understand the way to deal with quality aspects(Augusto, Lisboa, Yasin, 2014). Leadership plays an important in quality management; therefore suitable leadership should be instituted accordingly(Davis, Lockwood, Pantelidis, Alcott, 2013). All the prospects of challenges and issues should be minimized through driving out the scope of fear. There should not be any barrier between staff areas to control organizational work practices. Domino's should ensure that targets are not determined for the employees since that can create burden and can also hamper quality prospects. The management of Domino's should also ensure to eliminate numerical goal for the employees. The system of performance management should be changed accordingly; therefore there should not be any rating system for the employees(Dale, 2015). Employees should be provided the opportunity to educate themselves which can lead to self-improvement. This is yet another chance of developing organizational performance. Lastly, in the process of change, top authorities of Domino's are entitled to employ equal rights and obligations to the employees so that all can contribute to accomplishing the aims. Apart from this, Crosby's 14 steps to quality improvement can also be adopted at Domino's to implement the plan of total quality management. The management of Domino's needs to show greater commitment to improving quality processes, and it should also be communicated to all the employees of Domino's. At the next stage, Domino's must also form quality improvement team so that the can contribute to the development of business standards. There should be a specific measure of quality in current practices, and that should be done prior Domino's establishes a plan for quality improvement(Chaudary, Zafar, Salman, 2015). Identification of cost for quality is also essential to implement the methods in suitable methods. Domino's should work on generating awareness among the employees regarding the importance of quality management. This can help the employees to contribute to organizational development. Afterwards, quality problems should also be identified at the same time so that corrective actions can be taken accordingly. The Proper system must be implemented in this area. Domino's should also plan for zero defects by showing greater commitment towards quality aspects of products and services(Bon Mustafa, 2013). All the supervisors of Domino's are entitled to maintain quality dimensions and for that training sessions are essential. Employees should execute total quality management process through eradicating all defects and challenges. The management of Domino's should involve everyone in goal setting so that overall improvement can be facilitated. Along with employees, management should also try to eliminate causes of errors through observation and survey. Employee recognition also holds importance in quality development, and this also allows the employees to participate in goal achievement procedure(Barata Cunha, 2017). Afterwards, quality councils should be created through emphasizing on specialist procedures. However, quality councils should meet on a regular basis. At last, the process of total quality management should be reviewed and analyzed to identify its contribution in the development of Domino's. Conclusion On the basis of entire discussion, it can be said that focus on quality is crucial as that not only improves the standard of business; but also it provides more opportunities for growth and success. From the research, it is identified that prior executing any process into practice; Domino's needs to ensure that it is suitable in eradicating all the defects and errors. Thus, on such basis, it is recommended that Domino's should facilitate equal participation of all the employees so that all can contribute to organizational development. Moreover, Domino's should also show greater commitment towards quality aspects; hence appropriate provision should be there for the employee training and coaching within the workplace.

Potlatch - The Sharing And Shaming Essays - Giving, Chinook Jargon
Potlatch - The Sharing And Shaming Anth 166 Potlatch- The Sharing and Shaming A potlatch is defined by Barbara Miller as ?A grand feast in which guests are invited to eat and to receive gifts from the hosts.? This is shown in the last film we saw, Ongka's Big Moka. Ongka had been the receiving end at a potlatch in the past, and it was his turn to provide the feast. However, ?Later, when it is the guest's turn to hold a potlatch, they will try to give away as much as - or more than - their host did, thus shaming him into giving the next potlatch.? We see this in the way Ongka feels compelled to provide almost 200 more pigs than his hosts did when he was their guest. Ongka's people did not have any kind of wealth (other than animals). Whatever type of class structure there might be came from the amount a person would give at their potlatch. The functional theory Miller refers to ?looks at a given practice or belief in terms of its contribution to the cultural continuity.? The contribution to the cultural community. When a person gives a great amount at a potlatch, because it is a contribution to the cultural community, that person gains a certain stature. Therefore, it is not really the generous nature of a person that leads him to provide these things for his community, but rather, the stature that they can gain from this donation. This is not true of the Igbo people in Chinua Achebe's Things Fall Apart. While the Igbo people do engage in reciprocal gift giving, they are more apt to share with a guest the kola nuts which contain, like coffee, a mild stimulant. In the Igbo culture, wealth is more determined by the amount of wives and children that he can support. This may be seen as true with Ongka too; since the wealth in that culture is determined mainly by animals and the amount they can provide at a potlatch, these things are similar to what is needed to support a family. ?Potlatching demonstrates how closely linked production, consumption, and exchange are.? Potlatching not only demonstrates these things, but also demonstrates how wealth and stature are perceived and achieved in these cultures. It is a way to provide for others as well, but more than that, a way to provide for onself and one's family. When one holds a potlatch, one can expect the favor to be returned. For Ongka, he had to provide more than the person who held the potlatch he went to, but he also knew that in the future, he would be invited to one even larger. Anthropology

How I Funded My Mission, Wrote My Book and Made Bulk Book Sales with Grants
How I Funded My Mission, Wrote My Book and Made Bulk Book Sales with Grants I started with a heart centered mission and a newly published book, How to Raise Respectful Parents: Better Communication with Teens and Parents. Like all new authors, I was proud of it, but I soon learned writing and publishing a book are only half the journey. I had to market, and I wanted to market it to those who needed my message the most. Grant writing is my day job. I knew funds were available for the kind of materials and workshops I wanted to offer. Often authors think that they can only apply for grants directly to fund themselves as writers to write their book. While that is possible; itââ¬â¢s rare and highly competitive. I sought a large entity/business with which my mission aligned with theirs: the school district. I offered to write grants for school programs for FREE. Yes, for FREE! In exchange for this service, I requested that I be allowed to write my workshops and books into the grant budget. School programs hurt for time and dollars. Since there was no expenditure of time and effort on the part of their personnel, they agreed. First Grant to Write the Book I interviewed the parent engagement coordinator and learned about the unique aspects of her program. I suggested that I use my expertise to better train her parent educators. I was delighted when she said, ââ¬Å"yes.â⬠I wrote a small grant to a local private family foundation and they funded us. I was hired under the grant to conduct training for the school districtââ¬â¢s parent educators. The development of those training materials became the basis of my first book. In effect, I wrote the first draft of my book with grant funds while providing a needed service to the school partner. Second Grant with Surprise Bulk Book Sales The second grant funding for my mission came through an existing afterschool program grant. Because of the positive relationships built during the first grant funded opportunity, I negotiated the opportunity to provide a series of teen and parent communication workshops funded through their afterschool grant. I shared that I was willing to donate 10 copies of my book for the workshop. The project coordinator liked the book and decided to purchase more copies. She ordered enough for each family in the workshop a total of 50 books! Just like that, I made my first bulk book sale. Ripple Effects Since my initial success, Iââ¬â¢ve helped two author friends find grant funding for their heart- centered missions. I interviewed them and wrote grant proposals for each. One friend funded bulk book sales with her grant template and the other friend funded her one woman show with writing workshop materials with a grant proposal. As a result, I have been asked to write a book about grant writing for authors. The Quick Start Guide to Grant Writing will be released in 2018.

Outline Types for Research Papers
Outline Types for Research Papers Outline Types for Research Papers Your first step when writing a research paper is the outline. It helps you arrange your thoughts and keeps ideas coherent. Whether the paper is meant to be a lengthy discussion or a short presentation, an outline is a useful guide for the writer. There is no single, correct way to write an outline. The best outline is one youââ¬â¢re comfortable creating and is appropriate for the assignment. Here are some types of outlines for research papers: Informal Outline Starting with an informal outline will help you concentrate and list your thoughts. Youââ¬â¢ll discover which points youââ¬â¢d like to emphasize, the details you lack, and how youââ¬â¢d like the paper to look. The informal outline consists mainly of words or phrases, with only bullets or numbers as a format. This kind of outline is especially handy when youââ¬â¢re pressed for time and need to draft something quickly. Formal Outline When writing a more formal or longer paper, or when you have more time to prepare the work, constructing a formal outline is a good idea. You can begin with an informal outline and transform it later With a formal outline, a specific format must be followed. Roman numerals, letters and numbers are used to organize the ideas. The phrase or sentence structure of the main points and supporting points must be the same. Both formal and informal outlines can be further expanded to form topic or sentence outlines: Topic Outline In a topic outline, your ideas and explanations are sorted and distributed into different parts. Each part focuses on a certain topic (written in phrase form), and enumerates the details below. The usual format for topic outlines is Roman numerals for the main points, capital letters for the topics under each main point, and numbers for those under the sub-topics. Sentence Outline The sentence outline presents (in sentence form) the proofs supporting your thesis statement. The summary of the entire research paper is embodied in the sentences of this outline. The main points are labelled with Roman numerals, the supporting points for each labelled with capital letters, and details for each supporting point labelled with numbers. Reverse Outline While formal and informal outlines are created before the actual writing of the paper, the reverse outline is developed when youââ¬â¢re done with an initial draft. It can be used to check: If the draft accomplishes its purpose If all key elements are present If the order of ideas makes sense To create a reverse outline, determine the main idea of each of your paragraphs. When combined, they should form the summary of your thesis statement. Following an outline helps you keep ideas clear and that you donââ¬â¢t neglect any important information. There can be instances when you need to make changes or add to your outline, but your main points should remain the same. If you need assistance drafting any research papers, in Ontario and Canada is available for your academic needs. Our team is committed to helping you compose, proofread, and edit your essays.

Biology DB 5 Essay Example | Topics and Well Written Essays - 500 words
Biology DB 5 - Essay Example Support is a function that is mainly conducted by the stem, and for this reason a yam is modification of a normal plant. Botanically yams are in the family of monocotyledonous referred to as Dioscoreaceae and genus Dioscorea. The main reason as to why they are grown is because of their tuber or storage organs. The root cortex of a yam as compared to that of a corn is huge, which enables it to store sugar, starch and other substances. Casparian strip, which is water-impermeable strip of waxy material situated in the endodermis does not control uptake of minerals into the xylem as compared to other plants such as corn plants. This is because most of the minerals are stored and retained in the root, which functions as a stem. Yam as a plant can be said to support leaves because a stem is absent, the anatomy of yam as a plant can be said to be a modification of other standard plant. Animals and animal products are beneficial to human beings for different purposes other than for food. Animal products are highly beneficial in production of materials for clothes. Pigs are essential in production of valuable products such as suede for manufacture of clothes and production of shoes. Cattle produce leather which is sourced from the hides in the animal skin. The leather is used in the manufacture of clothes, shoes, purses, wallets and car upholstery. Feathers from poultry especially from geese and ducks are important in stuffing down clothes such as pillows and jackets. Sheep is a great source of wool that is used in processing yarn for knitting socks, shirts and other different cloths. Rabbits are a source of far used in knitting socks, yarn and other types of clothing. The most important benefit of animals is medicinal applications. Animal products have been tested methodically as a source of drugs especially in modern medicine. For instance, a snake venom is used as an

Zulu African Tribe views on death and afterlife Term Paper
Zulu African Tribe views on death and afterlife - Term Paper Example It is believed that in the 16th century the Zulu migrated and settled in the south of the African continent. This paper is to examine the practices, customs, belief and views of the Zulu, a tribe found in South Africa regarding death and the afterlife. The Zulu tribe views on death and the afterlife The Zulu belief in gods, for instance, Inkosi Yezulu means ââ¬ËChief of the Skyââ¬â¢. This is a male god of the sky and is considered as the maker of all humans (Magesa, 187). However, despite him being the maker of everything, he is associated with lightening, thunder and rain clouds. This male god has a twin god called mother earth (Krige 46). The Zulu as well believe people who die go to the twin god. The Zulu also identify their ancestral spirits by names like amalozi, amathonga and amakhosi. This ancestral spirits are souls of the recently dead people and are normally considered effective contacts between the Zulu and their gods and therefore responsible for positive, construct ive and creative results among the Zulu. At the same time these ancestral spirits can also work for the ill of the tribe (Krige, 47). For this reason the Zulu hold these ancestors in high esteem so as to bring good will to the region. Umsamo is a particular place identified in the Zulu hut of Zulu chiefsââ¬â¢ jurisdiction where religious action is done.... Besides, their bodies are quietly unceremoniously buried. Ceremonies and rituals associated with death and the afterlife Immediately after death, one is considered to be in an "in-between" region which is some kind of limbo. The Zulu believe that the dead person stays in this ââ¬Ëin-betweenââ¬â¢ situation for a period that could be between one month and a year. However, being in this limbo position is necessitated by three things. One of the reasons for this is that after a personââ¬â¢s death, the villageââ¬â¢s chief herbalist will be devoted with finding out the cause of the departedââ¬â¢s death. These search periods will last for about one month, besides; if the person was not married he would be in limbo for that period of time until the cause of his demise is traced. In the event that he was married, the widow would mourn for a period of twelve months since the death occurred. A ritual is carried out which involves taking of medicine and praying to prior to beseech ing the current Chief to perform what is known as Ukubuyisa Idlozi. This is normally done as an initiation to "bring home the ancestor"(Lawson 32). They believe that this act makes it possible for the recently deceased person to join his ancestors in the Umsamo. Once the deceased person has been brought to the Umsamo, his position in this place will determine where he goes after here. In the event that a chief dies, the Zulu believe that his spirit will remain within the living world so as to oversee the happenings his homestead even in death. Except for Chiefs, it is believed that all those who die go to the underworld, which is located deep inside mother earth (Tempels 38). Ethical responsibilities and obligations to achieve the afterlife When a family member dies, the remaining family

Critique of the Ramayana Modern Prose Translation Essay Example for Free
Critique of the Ramayana Modern Prose Translation Essay In a just world, Mr. R. K. Narayanââ¬â¢s estate would be responsible for reimbursing seventeen-fifty, plus applicable taxes, to all those who purchased the Penguin Classics 2006 publication of his book, The Ramayana: A Shortened Modern Prose Version of the Indian Epic. Stated clearly on the back of the cover is the promise that R. K. Narayan ââ¬Å"recounts [The Ramayana] with the narrative flair of a master novelistââ¬â¢Ã¢â¬â¢. The back cover lied. Narayanââ¬â¢s re-telling condenses the epic poem so much to the point of nearly listing a series of events. No matter the inspiration, Narayanââ¬â¢s The Ramayana is still a story, and should therefore be able to stand on itââ¬â¢s own as a captivating taleââ¬âwith further literary research or expansion being used to enhance itââ¬â¢s appeal, not explain it. Arguably, the ââ¬Ënarrative flairââ¬â¢ of this re-telling is little more expressive than unsolicited summaries found on the Internet, and without further literary aide or instruction, does not stand as a solid piece of literature. What is worse, is that instead of allowing a greater breadth of readers to relate and experience tale of the Ramayana, new readers are alienated by itââ¬â¢s convoluted atmosphere. While the task is grand, Narayanââ¬â¢s translation is not listed as an aide to a larger, more in-depth version; it is still a novel and as such needs to be able to stand strong in its own right when evaluated alone. People who have no prior knowledge of the original Sanskrit story, and who have not been raised with the Hindu epic as a part of their life, should be able to pick up this book, read it, andââ¬âregardless of how far the tale may go in global historyââ¬âbe able to enjoy one hundred and fifty one pages of literature, without having any prior knowledge, or requiring further research. Having more knowledge, and doing more research on the original epic tale should increase what readers are able to receive from the book, but it should not be necessary in order to understand it. As it stands, without knowing the original tale, new readers are left with very little literary flow and a patchy depiction of what is supposed to be a lush world. At one point, while Bharatha and Rama argue as to who should be the rightful king, their entire episode is related with: ââ¬Å" The argument went on at a highly academic and philosophical level, the entire assembly watching with respect. (Narayan 60) That assertion does not express a deep academic and philosophical argument, but rather states that one was occurring; the reader doesnââ¬â¢t get to experience what transpired between the brothers, or garner any emotion from it. It goes on to almost quite literally depict the event with a he-said/he-said monotony: So be it; if I have the authorityââ¬âthen I confer it on you as the ruler,â⬠said Bharatha at one stage. ââ¬Å"On my command as the ruler, if you desire to think so, you shall be the King. â⬠It went on thus. Rama went on repeating that there could be no word higher than that of a father; no conduct other than obedience to it. Throughout he referred to Kaikeyi in the gentlest terms and always as ââ¬Å"motherâ⬠. (Narayan 61) The listed manner in which the plot is unfolded by Narayanââ¬â¢s re-telling is barely more narrative as a piece of literature than an excerpt from that of the free online encyclopedia Wikipedia: Bharatha refuses to profit from his mothers wicked scheming and visits Rama in the forest. He requests Rama to return and rule. But Rama, determined to carry out his fathers orders to the letter, refuses to return before the period of exile. However, Bharatha carries Ramas sandals, and keeps them on the throne, while he rules as Ramas regent. (Wikipedia Contributors) There is very little more efficiency or flair in Narayanââ¬â¢s telling, and in fact, Wikipedia depicts the stages of the long tale with better clarity; if the prose is not going to be linguistically lush and evocative, it may as well be clear (Wikipedia is not only clear, but free of charge as well). It is of course not a simple task to undertake translating an epic poem from a rhythmic language, into prose with a language devoid of the same musicality. However, to the novice reader of The Ramayana, they would not know the difficulty of the task, and thusââ¬âhowever harsh it may seemââ¬â should not be a factor in the reviewing of the story as it stands alone. Narayan was by no means an incapable writer, and as winner of numerous awards and accoladesââ¬ânot the least of which being multiple nominations for the Nobel Prize in Literature (Rajnish Wattas), he does not need defending that he has great ability as a writer, yet the bottom line remain that when it is stripped of further discussion, research, and introductions, The Ramayana: A Shortened Modern Prose Version of the Indian Epic just does not stand on itââ¬â¢s own as captivating modern prose. With nearly each new episode of the tale, Narayan prefaces the action with even more listed information, take for example the introduction to the chapter of Vali: The characters in the drama that follows are Vali, Sugreeva, Hanuman, and Rama. The action takes place in the mountainous forest regions of Kiskinda, a kingdom ruled and inhabited by monkeys. In the Ramayana, the articipants are not only human beings, but many others from Godââ¬â¢s creation, intelligent, cultured and with their own achievements of spirit as well as physique: Jambavan was a bear, Jatayu was an eagle, Lakshmanaââ¬âRamaââ¬â¢s brotherââ¬âwas himself a human incarnation of the Great Serpent Adisesha in whose coils Vishnu rested. (Narayan 90) Again, the story is told by listing statements of what is going on. As with the landscape, and even the characters themselves, nothing is depicted in the story-writing of the prose, but stated, as if the entire epic was a news article being reported by Narayan, as opposed to a vivid history with grand escapades and extreme characters. By translating an epic tale from poetic verse into shortened modern prose, the objective is ultimately to enable a broader audience to relate to and appreciate a classic tale. Poetry is a secluded literary world that does not have the mass appeal that modern prose does; yet Narayanââ¬â¢s re-telling is too constrained and overwhelmed by the amount of story condensed into it. By trying to constrain the length of the story to allow for more readers to get through it, Narayanââ¬â¢s ââ¬Ëmaster narrative flairââ¬â¢ seems lost, and the epic tale is a heavy list of events that merely occur on the page.

A Media Specialistââ¬â¢s Role in the Research Process :: Librarians Library Media Specialist Role Essays
A Media Specialistââ¬â¢s Role in the Research Process When settlers from the East planned to ââ¬Å"go West,â⬠they faced many challenges. Becoming hopelessly lost was likely. Starvation was a possibility. Floods threatened total destruction. Settlers needed an experienced guide to lead them to their destination. When students begin research projects, they face similar challengesââ¬âalthough the challenges are intellectual rather than physical. They can become hopelessly lost as they try to follow Internet links from one site to another. They can be starved for good information. They can be flooded with note cards that contain bland and useless facts. Students need a guide. They need a school librarian who can lead them along the trail of solid, meaningful research. The librarian must understand the studentââ¬â¢s assignment, assist with locating helpful resources, and know the basic processes for writing a research paper. Understanding the studentââ¬â¢s research project assignment requires conducting a reference interview. In the Online Dictionary of Library and Information Science by Joan M. Reitz, a reference interview is defined as ââ¬Å"the interpersonal communication that occurs between a reference librarian and a library user to determine the personââ¬â¢s specific information need(s), which may turn out to be different than the reference question as initially posed.â⬠The key to this interview is good communication initiated by the librarian. Before any exchange of information takes place, an ââ¬Å"attitudeâ⬠exists. ââ¬Å"How the student perceives his or her question will be receivedâ⬠(Riedling) contributes to the overall tone of the interview. The librarian must provide an atmosphere that is comfortable for the student to seek information. In addition to the physical surroundings, the librarian must use both verbal and nonverbal skills to encourage the student. According to Riedling, nonverbal strategies include ââ¬Å"physical gestures, posture, facial expressions, tone of voice, and eye contact.â⬠The media specialist must ask open questions and practice active listening, while utilizing other verbal skills including ââ¬Å"remembering, restating, paraphrasing, closure, and inclusion.â⬠(Underdown) The librarian must determine just what sort of information is needed and the depth that is required. The process is accurately summed up by Riedlingââ¬â¢s statement ââ¬Å"that a successful reference interview is one in which the student feels satisfied that you have given personal attention and accurate information.

Critical reflections on the Westphalian assumptions Essay
Reflection Piece Critical reflections on the Westphalian assumptions of international law and organization: a crisis of legitimacy. Although the lack of world government, most people agree that there is a body of norms and rules of conduct that generate international law. International law has generally examinated from two dissimilar positions. When power and interests clashes, skeptics see international law as a insignificant and nonexistent. Especially, the article of A. Claire Outler focuses on this problem. However,others have occasionally seen international law as a strong tool to organize and change the behaviour of states for the better. The main impotance or constraint of international law is the conflicting and generally uncertain provisions in international treaties and conventions. Also, legal system lacks the compulsory Juristiction and an adopted hierarchy because most powerful and developed countries ignore and try to run way the limitations of international law. I think that this situation clearly shows the weaknesses of international law. A influential legal code requires to reconcile itself to actual behaviour of individuals and states and not try to essentially remake them according to abstract moral principles. In general, realist are more suspicious about the issue of international law on the other hand,liberals and constructivist rely on it is, and should be, a crucial force shaping the behavior of states. To sum up, I think that this article was a very useful because it shows the negative and positive aspects of the issue clearly. However, some part of the article was a little bit biased about the validity of international law. It generally focuses on deficiencies of international law. I agree that there is lack of world government and international law hasnââ¬â¢t compulsory Jurisdiction but this doesnââ¬â¢t mean that international law is not real and necessary law.

Compare and contrast a spiritual and an educational feminist
Compare and contrast a spiritual and an educational feminist Over the years, various women movements have arisen to campaign for the conferment of equal rights for both men and women. The first women movement had the chief intention of campaigning for suffrage rights. Since then, other movements came into being seeking to accord women economic, social and educational rights tantamount to those available to men.Advertising We will write a custom essay sample on Compare and contrast a spiritual and an educational feminist specifically for you for only $16.05 $11/page Learn More In this context, those people who believe in equality in human rights, both men and women are referred to as feminists. Consequently, feminism entails all the movements established with the intention of campaigning for equality in economic and social equality rights coupled with the creation of equal opportunities for both genders. Feminists ââ¬Å"oppose anything that is detrimental to the societal growth of women. With regard to Bart, ââ¬Å"a feminist speaks or writes against sexual harassment, sexual assault and domestic violenceâ⬠(538). A Feminist is, therefore, in the simplest terms that person who believes in gender equality. From this end, the writerââ¬â¢s personal definition of feminism may suffer some detriments perhaps following the need to include aspects such as writing and acting coupled with other issues relating to women rights including injustices and social status quo in a single definition. Perhaps attempting to consider the a historical era and momentous events that brought into being the concepts of feminism takes people suffrage endeavors in early 1930ââ¬â¢sAmerica. Suffrage refers to womenââ¬â¢s rights in voting. However, according to Krolokke and Sorensen, ââ¬Å"the expression is also used for the economic and political reform movements aimed at extending rights to women and without any restrictions or qualifications such as property ownership, payment of tax or material statusâ⬠(10). Through feminists efforts, by 1960ââ¬â¢s, women had acquired some voting rights in Sweden, the United States, and Britain. Success in fighting for suffrage evidently marked the onset of other feministââ¬â¢s movements and the emergence of feminist thinkers.Advertising Looking for essay on gender studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More The modern feminists movements emerged depending on the existence of certain issues that tend to disfavor women. One may view modern feminism may as comprising of three waves. The first wave ââ¬Å"refers to the movement of the nineteenth century all the way to the twentieth century, which dealt mainly with suffrage, working conditions and educational rights for women and girlsâ⬠(Humm 251). The second wave predominantly focused on issues relating to persisting inequalities in law culture, and advocating for roles of women in the society that undermine both their integ rity and position in society. This movement lasted between 1960 to early 1980ââ¬â¢s. The third wave took up soon after the end of the second wave. It sought to address perceived failures of the second wave along side with continuation of the achievements of the second wave. Educational feminists campaign for women rights from all contexts in the society right from economic to social perspectives. Religious feminists look at religion from women perspectives. As Stone reckons, religious feminism is a ââ¬Å"field that studies the scriptures and religious texts from a feminist perspectiveâ⬠(40). Consequently, religious feminism focus on the interrelationship of scriptures massage with customs, practices, theologies and traditions from the perspectives that guarantee equality to all genders. One of the areas of focus of the religious feminism is perhaps the dominance of men clergies in various religions. Religious feminists attempt to increase the various roles assumed by women in religious institutions. Belenky and Goldberger posit that, ââ¬Å"feminist speaks also about the images of women in various established religious sacred textsâ⬠(80). In this regard, the functions of the religious feminists may be argued as predominantly inclined in the need to ensure equal presentation of women in all position of the religious leadership as their counterparts-men. On the other hand, educational feminism theorists argue, ââ¬Å"the educational structures are flawed in their overemphasis on progress as the highest value and the competition to attain itâ⬠(De Vaney 568). Additionally, educational feminists argue that overemphasis on quality, with the belief that men are more capable to deliver it as compared to women, serves to marginalize women, and minority groups. According to Hart, the systems that are engineered with hierarchical structures need to be altered to promote ââ¬Å"equal valuing of knowledge, human intelligence, critical thinking, and cr eativityâ⬠(98). Furthermore, opposed to religious feminists, educational feminists show much concern on issues of marginalization of women in work places, and even in educational institutions settings.Advertising We will write a custom essay sample on Compare and contrast a spiritual and an educational feminist specifically for you for only $16.05 $11/page Learn More Adding on this, Martin et al. argues, ââ¬Å"Feminist pedagogies have developed, in response to feminist, claims that classrooms are patriarchal, competitive, and hierarchicalâ⬠(Para.10). Educators of feminists, consequently, emphasize that people need to gear the key concerns of education need towards fostering social activities, which predominately ensure cute integration of collaboration learning projects, as opposed to individualistic activities, which only enhance divisions and competitions in schools. Additionally, educational feminists go to the extent of performing studies t hat seek to show that, given opportunities, women can perform equally or even better than men in tasks that have stereotypically perceived as districts of men. Huff and Cooper conducted one of such studies in 1987. In this study, Huff and Cooper sought to address issues pertaining to design of software among educators that could enable students use commas without errors. When female educators were put to task to write the software, there was no difference between the software written by them and boys. Consequently, Huff and cooper deduced that ââ¬Å"student programs are the most game-like, boy programs are in the middle and girls programs are on the learning tool side of the function (529). They express concern that the educators may have been simply using male as the default value of student' (Huff and Cooper 529). Arguably, this research indicates the concerns of educational feminists in campaigning for incorporation of women in information technology since they have equal chance s of excelling as men. Thus, it may be substantial to make an assumption that, if educational feminists views are things to go by, perhaps the next software developer which will revolution the worldââ¬â¢s current software market will have a woman name behind it. According to the definition of feminism given by the author, various limitations and acts of resistance while not negating some strengths are worthwhile for consideration. According to the author, feminism infers putting women into perspectives in all societal activities including politics, economic sectors and more importantly equal rights for access of education for both girl and boy child.Advertising Looking for essay on gender studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More Concerning the definition, society, especially modern society, that seeks to prosper in all pillars that anchor it, cannot perhaps achieve its developmental goals without proactive interplay of all genders. Additionally, a more balanced society in terms of universalism of roles allocation is perhaps only to be born only when all potentials are tapped among women and men collectively. Adequate scholarly evidence is available showing that men and women can perform equally in all sectors of economy (Oram 5). All that people desire is the creation of opportunities for women to compete freely with men. This is the aim of the endeavors of feminism activities, as implied by the definition adopted by the author. While this gives the definition adopted by the author some strength, some limitation may perhaps also be evident. For instance, while feministââ¬â¢s endeavors to accord women equal opportunities for women and men, to some extent critics concur that not all jobs can be equally acc essible to both men and women. For instance psychologically women have been found to be well talented with oratory skills as opposed men and hence well suited for jobs such receptionists and secretarial. Conclusively, the paper finds it subtle to uphold the spirit of feminism. Feminism, as people discuss it, is a phenomenon that came into dominance in the early 1930 when women movements were seeking to secure suffrage rights. Though initially headed by women only, the calls for these movements attracted even men. Consequently, the word feminist was coined to refer to all people (of both genders) that support equality for women. The movement seeking the suffrage rights for women formed the first wave of the feminism movements, which lasted until 1960ââ¬â¢s. Subsequent waves extended the fights for women rights in other areas: something that gives rise to various forms of feminisms among them religious feminism, cultural feminism, educational feminism among others. However, two of these types of feminism have been given a detailed introspection in this paper: religious and educational feminism. Bart, Pauline. Feminism Unmodified.

HALTH Essay Example | Topics and Well Written Essays - 500 words
HALTH - Essay Example The findings from the interview would be summarized to respond to the following question: ââ¬Å"Does marital satisfaction decrease with children? Two different sets of married couples were interviewed. One set had been married for more than five years and have three children. The other set of couples had been married for seven years but they did not have any children. The results of the interview are presented in tabular format as shown below: From the results of the interview, it could be deduced that marital satisfaction does not only depend on the factor of raising children. For both sets of couples, it could be observed that both were relatively happy and satisfied (with or without children). It is therefore evident that couples indeed would have wanted to have children, if given the chance. For the couples without children, it was relayed that they wanted to raise them but since the wife was already in her late or mature age when they got married, biological reasons prevented them doing so. As such, they learned to accept the fact that they could not have children and it was evident from their relationship that their satisfaction and happiness was not diminished by not having children. For the couple with three children, it was noted that children provided them with happiness that strengthened their marital bond. There were challenges in terms of meeting financial obligations and supporting the needs of the children; but this was accepted to be part of life. It was noted to have actually helped in striving to work harder to support the childrenââ¬â¢s needs and to try as much as they can to avail of much entertainment, leisure and relaxation as they could possibly accommodate. Overall, the interview results indicated that although children could have significantly contributed to providing happiness and a sense of fulfillment to married couples, this is not the sole factor that determines marital satisfaction. Even couples who do not have

There are many popularly suggested business objectives, while Essay
There are many popularly suggested business objectives, while academically the objective to maximise shareholder wealth is considered superior. Discuss. (In y - Essay Example Despite these claims, research suggests that maximizing shareholder wealth is considered superior to all objectives. Wal-Mart claims to hold down inflation in the US (Fishman, 2003), create jobs, and has customer-centered strategy as their prices are unbeatable, but they ultimately squeeze the vendors and under-pay the staff (Heyer, 2005) with the ultimate goal of maximizing shareholder wealth. They even have an efficient supply chain and source their products from developing countries and claim to be a part of their growth. Nevertheless, employee wages at Wal-Mart are as much as 31% lower than competitors (Nester, 2006). It pays practically no benefits and very often employees have to work overtime without any additional compensation. Wal-Mart ranked fourth in terms of social responsibility in terms of its dealings with its stakeholders but there were 4851 claims filed against it in the court (Papasolomou-Doukakis, Krambia-Kapardis & Katsioloudes, 2005). Corporate giants like the CEO of Coca-Cola too make tall claims that by being more efficient and more profitable, it makes businesses better for the community (Ash, 2004) but findings reveal otherwise. They have committed as many as 179 major Human Rights violations (Cairns, 2005). The union leader was shot dead at the Columbia bottling plant. Turkish and Indonesian workers face mass firings for their union activity. Multination Monitor, an American nonââ¬âprofit organization, listed coke amongst the worst ten companies in US. In India they are diverting potable water from local residents for the production of soft drinks. During the processing of soda pop in India, Coke has contaminated soil and underground water with toxic cadmium, which was found in the sludge. They have also been charged and found guilty of bribing the Pollution Control Board in South India. They are accused of inflating profits, selling contaminated beverages and violating contracts.

Labs 1,2,3,4,5,6,7 Lab Report Example | Topics and Well Written Essays - 2500 words
Labs 1,2,3,4,5,6,7 - Lab Report Example Label the Force Gravity (=mg), the Nor-mal Force (FN), and the Friction Force (Ff), but donââ¬â¢t use any specific numbers. What makes this a state of equilibrium? The cups are in a state of equilibrium just before it starts to slide. This is because the mg of each cup is made negligible by each normal force. Movement of the cups is being restricted by frictional force which acts on the cups. Only when an external force will be applied opposite to that of the frictional force will the cups begin to slide. If the co-efficient of friction is high then more force will be required since the opposing force also increases. However if the co-efficient of friction is low then the force required would also be low since lesser frictional force will be acting on the object. Lab 2 taught me the different forces that work on an object which is in state of motion of at rest. It gave me sound knowledge as to what forces are responsible for maintaining equilibrium of any body. Concepts about momentum of bodies and how mass has an effect on acceleration pr retardation became much clearer since we experience all of this in our day to day lives and getting to know about each thing from a scientific point of view made it fun. Each of the above observations explains the law of inertia. In the first observation since the water was still at one place at first and the bowl is accelerated, the water tries to stay behind while the bowl moves forwards immediately and the water spills back. However when I walk at steady speed nothing happens since no external force is there and the water tends to be at one place. When I walk straight the water tends to be in the forwards direction but since I turn rightly abruptly, the water spills since its motion was in the front and the sudden change in direction caused spilling. Inertia is also seen when I walk with the water bowl and the

Polymer Suspension Based Shear Thickening Fluid Fabric
Polymer Suspension Based Shear Thickening Fluid Fabric Polymer suspension based shear thickening fluid-fabric for protective applications was a new idea. Shear thickening fluid was also known as STF. Generally STF contains liquid medium and solid particles which can be inorganic or organic based. Basically, the viscosity of the Shear Thickening Fluid (STF) will be increased when shear stress increasing. By exploiting this fluid deformation from STF, for the fabric itself, the friction between yarn-yarn and fiber-fiber will be increased drastically when force applied over the fabric composite. Then, the fabric itself will be having higher energy absorption when STF impregnated with the fabric itself compared with un-impregnated fabric composite. The reason for this selection was motivated by previous works in this area, as well as the beneficial characteristics provided by these two materials. US Patents 5599290 and 5545128 have developed Bone fracture prevention garment and method. In these two works, carried out by the same authors, the patent outlines a design used to resolve the issue of the harmful effects of impacts on the bones of elderly individuals. This design was described as being composed of the following: the component includes a dilatant material that was relatively stiff near the time of impact and relatively fluid at other times. In a preferred embodiment, the invention provides a hip pad, possessing a thickness small enough to be compatible with wearer acceptability, that conforms to the shape of the body during everyday activities such as walking, sitting, and sleeping, and was thus comfortable to the wearer (5-14). In order to model the rheological behavior of these fluids, it has been proposed to use a power law analysis with the relationship between the viscosity and shear rate represented by ÃŽà · = k à ½n-1 Where k is the fluids consistency and n is the power law exponent specific to the region of high or low viscosity. According to Barnes, the shear-thinning and shear-thickening regions can be accounted for by, using the sum of two power laws, with one value of n less than unity and one greater. (8) The rheology studied will be focused on colloidal suspension rather than hard particle suspension. Hard particle suspension like silica particle, was extensively studied by many researched over the world like Wagner and Lee Barnes (5 8) .They claimed, the hard particle suspended in the polyethylene glycol (carrier fluid) will exhibit shear thickening behavior by varying the volume fraction of the particle over carrier fluid from, above 40% to 55%. 30% by volume fraction will not exhibit shear thickening behavior but in Ragvahan experiments showed (10), by using 10% volume fraction of fumed silica suspended in the Polypropylene glycol (PPG), shear thickening behavior had occurred but likely referred to particle agglomeration( flocculated gel) rather than hydrocluster because fumed silica, naturally have low surface area and larger particle size. In the experiment, the onset transition called critical shear rate seems having two points, the higher and the lower shear strain, due to th e original structure of the carrier fluid itself (polypropylene glycol). The formation of vinyl group and straight chain in PPG gave two formations of clusters (10). Colloidal suspension study was not emphasized and thoroughly studied because of the complexity of the colloidal system itself, which normally involved many factors such as steric and electrostatic stabilize, stability of the suspension and the formation of the hydrocluster via modification of the interaction particle of the colloidal suspension. In chapter 2, theoretical discussion about colloidal suspension which contributed to the new phenomenon of Shear Thickening Fluid (STF) such as structure-relationship of the colloidal suspension in polymer solution and Solid/Liquid transition (SLT) and also liquid/Solid transition (LST) [17]. According to the DVLO theory, stabilization of particle in the suspension with steric and electrostatic (will be have detailed explanation in the chapter 2) charges are important parameters to be investigated. The colloid particles were also known as surface charge particle. It involved the attraction and repulsive force for every single particle in the colloid dispersion or suspension, which contributed to the shear thickening behavior of the STF. In this paper, colloidal suspension rheology will be main topics, by relating it with the structure-relationship and LST theory. In the chapter 2, more detailed onset transition of STF will be extensively discussed. Conventionally, the onset transition involved Order-Disorder transition (ODT) and hydrocluster. The main criteria in Shear Thickening Fluid (STF) were to predict critical shear rate which was the critical point when the particles were suspended in the STF. It started to cluster with each other, exhibiting shear thickening behavior upon increase in shear rate. There were many factors in STF, some of them were, volume fraction dependence (between particle and carrier fluid), particle shape and size dependence (porosity) and particle interaction dependence. The particles can be normal charge (hard particle such as fumed silica, clay and any metal oxide particle) or colloidal particle (with charge). In this paper, fumed silica will be used as a main material for hard particle as well as and colloid dispersion. Fumed silica will be turned into colloidal suspension by surrounding the charging over its surface particle. The main principal of colloidal suspension for this study was based on DVLO theory. Therefore, by studying the electrokinetic for each suspension, relation between this study with measured rheology through the power law index and yield stress value, there are possibilities to relate the structure- relationship in colloidal suspension of STF with onset transition (SLT LST) evaluated. There were two basic requirements for exhibiting shear thickening behavior from colloidal suspension [raghavan, wagner, barnes], firstly, the volume fraction of the solid in the suspension must be very high and secondly, suspension must be nonflocculated or deflocculated STF Fabric composite will be impregnated with STF has great potential in bullet proof application especially for soft armor. The vest will be having higher flexibility and less heavy than conventional soft armor. Wagner and his team claimed, STF will increase the friction between yarn-yarn and fiber-fiber by 500% using pull out yarn test. Also, by using NIJ as reference stabbed and puncture resistance test (NIJ 115.00) for STF Fabric composite, it easily passed level 1 protection. For the bullet test, also NIJ as reference, it showed interesting results. Instead of higher penetration from the bullet (9mm) to the conventional fabric composite, for STF-Fabric composite, bullet was deflected away (rebound) and had less significant mark over the top of the clay in tested frame panel. Basically, fabric composite will be placed over the top of the clay. The mark of the clay will be used as reference for the dissipated energy (energy absorption) from the test. A bigger diameter of the mark and the depth for the mark was deeper indicating the fabric composite has a low dissipated energy system. Smaller diameter of the mark and less depth of the indented clay, showed, a higher dissipated energy system for the fabric composite. 1.2 Problem Statement Wagner found that STF had rheological characteristic of dilatant but studied on the use of hard particle in suspension. Colloidal suspension of fume silica in polymeric aqueous media was performed by other researcher but they studied only ionic strength and critical shear rate effect. In depth study on formation of hydroclusters in colloid need to evaluated to relate structure relationship between shear thickening behavior of polymer suspension with regard to composition (volume fraction), particle porosity, size and shape of particle. Hence, viscosity measurements were evaluated for different polymer systems to determine the effect of these systems on critical shear rate and shear thickening phenomena. Stabbed and puncture resistant fabric composite employing STF with high spike and knife impact performance can be affected by the formulation of STF and adhesion between STF suspension and fabric yarn. Hence, this study is hoped to solve the problems faced by indepth understanding on rheological and performance aspects in the development of STF fabric composite for protective applications. 1.3 Objectives Of Study The specific objectives of the project include: To determine physical colloid properties of colloidal suspension from hard sphere particles and colloidal dispersion via zeta potential studies. To determine the rheological behaviors of the colloidal suspension from the effects of repulsion system present during steady shear experiments. To fabricate STF fabric composite using various layers of Kevlar 49 and cotton fabric and determine stab and puncture resistance of STF fabric composite according to standard NIJ 115.00 tests.

Al: Rheology of Polymers near Liquid-Solid Transitions CHAPTER TWO LITERATURE REVIEW 2.1 Shear Thickening Fluid (STF): Introduction Review Shear thickening fluid, basically have two different types of fluid behavior shear thinning and shear thickening. There are two types of shear thickening behavior in the fluid behavior. First, Shear thickening is a non-Newtonian flow behavior (dilatant) observed as an increase in viscosity with increasing shear rate or applied stress also known as time independent material (Barnes, 1989; Maranzano and Wagner, 2001; Lee and Wagner, 2003). Non-Newtonian flow behavior (rheopectics) observed as an increase in viscosity with increasing duration of stress (shear rate constant) known as the time dependent materials which have a memory to deform over period of time ( figure 1). Concentrated colloidal suspensions consisting of solid/hard spheres particles dispersed in a carrier liquid have been shown to exhibit rheological shear thickening behavior resulting in large, sometimes discontinuous increases in viscosity above a critical shear rate. This transition from a flowing liquid to a solid-like material is due to the formation of shear induced transient aggregates, or hydroclusters, that dramatically increase the viscosity of the fluid (Barnes, 1989; Maranzano and Wagner, 2001; Lee and Wagner, 2003). For stabilize the STF and avoiding agglomeration behavior, co-solvent is added and it must be done because STF has a very strong molecule interaction between particles and carrier fluid (attraction force) rather than repulsive force when force is applied at specific time (critical shear rate and critical shear stress) [Barnes, 1989; Maranzano and Wagner, 2001; Lee and Wagner, 2003]. The Shear Thickening Fluid (STF) is the combination of the particles suspended in the carrier fluid. Figure 2 showed the STF curve when shear stress applied on the material. The particles used can be made of various materials, such as Silica Dioxide or other oxides, or polymers such as Polystyrene (PS) or Polymethyl methacrylate (PMMA), or other polymers from emulsion polymerization. Generally, particles can be in various shapes like spherical, elliptical, disk-like or clay particles (Barnes, 1989). The particles can be stabilized in solution or dispersed by charge, Brownian motion, grafted polymers and others. Then, pH value of a suspension also contributed to the stability of suspension via colloidal condition such as steric repulsion and electrostatic system. The effects of pH value, concentration of the surfactant, and ionic strength of the surfactant are major factors for the colloidal suspension. This influence parameter is due to the agglomeration particle size (F. Rey, M.A. Ferreira et al. 1995).These are basic parameters in the rheological suspension and colloidal suspension system. Many studies of shear thickening fluid system (Barnes 1989, Hoffman 1998, Wagner 2004), focus on the colloidal particles only such as nanoparticles colloidal silica and monodisperse silica, which is it is well known as a very stable individual particle interaction in the suspension [Brownian suspension]. In this paper, electrostatic stabilize and steric repulsion system is used to control the interparticles interaction in the rheological suspension. Electrostatic stabilize is less studies due to the complexity in the rheological suspension. Concentration and ionic strength of the surfactant are the main parameter of this paper and the final pH value is critical measured in order to exhibit rheological shear thickening. F. Rey, and M.A. Ferreira in their paper Effect of concentration, pH, and ionic strength on the viscosity of solutions of a soil fulvic acid claims, all the parameter in this studies showed the dramatic instant result of the suspension due to the gel point of the suspension or well known as isoelectric point (iep) by adjusting H+ present in the rheological suspension. in addition of steric repulsion system, making a barriers for the individual surface particle is a intention in this paper. The double layers of the barriers (thickness) due to the zeta potential and elec trokinetic theories are independent from the shear stress during rheological experiments. Because of the main intention of this paper are to determine the factors involving onset transition of the STF due to the interparticle interaction dependence which are closely related to the colloidal suspension rheology and the effects of the onset transition (rheological behavior) for the stab and puncture resistance test of fabric composite. Then, the co-solvent that are used, it can be aqueous in nature and non-aqueous which can be chosen to stabilize suspension system The co-solvent should be environmentally stable like ethanol and methanol, so that, they remain integral to the fabric and suspended during service. Another function of co-solvent is to lower the viscosity of the STF, so that impregnation process of fabric composite becomes efficient and easy. By adjusting the viscosity of the STF, areal density of final fabric composite can be alter and also monitored. The particles must get through and suspended in the fiber-fiber and yarn-yarn [lee wagner et al 2003]. The result from the good impregnation process is the friction force between yarn-yarn and fiber-fiber will be increased [lee wagner et al 2003]. But in this paper, by using information from wagner and other researchers, a variation of the drying temperature for the STF and STF- fabric composite will be designed and tested via thermal degradation technique ( pre-degradation) and swelling behavior of the STF-fabric composite after at the different drying temperature. The idea are to avoid pre-degradation region and swelling behavior of the STF in the drying process which is believed will reduced the performance of the fabric composite due to the following factors, degradation of the STF and STF-fabric composite due to the drying temperature and swelling behavior of STF. By combination those factors, believed, the internal friction between fiber-fiber and yarn-yarn will be reduced which is making inefficiency of energy absorbtion or dissipated energy for fabric composite (Wagner 2004). 2.2 Mechanism of Shear Thickening Fluid (STF) The mechanism of STF normally can be described via hydrocluster theory and order-disorder theory. The similiarity of these theories is a idea of a new macrostructure formation occurred, furthermore, it are closely related to rheological experiments such as temperature and time factors. A few researchers like Barnes (1989), Hoffman (1998) and wagner (2004), claimed colloidal factors such as different types of carrier fluid, particles porosity, and volume fraction of particle suspended. But, these two theories still cant explain in detail about the mechanism of STF. Wagner and his team claimed the formation of hydrocluster must be a deflocculated suspension and major parmaters of STF are volume fraction, interparticle interaction, and particle porosity. A new theoretical transition will be proposed for STF behavior. Liquid-Solid transition (LST) or semi-solid transition involving the relaxation state of the fluid during transition which is normally include the changes of loss and stora ge modulus during transition and believed new formation of a new macrostructure are formed during rheological experiment. This a new macrostructure formed due to the formation of the attraction force and repulsion force in the STF, which is believed closely related with double layer theories in zeta potential theory. LST theories is based on the transition of the material due to the changing of the complex modulus which are can be translated into the formation of gel (stiffness) and relaxation state of the material during near transiton and at the onset transition. 2.2.1 Hydrocluster The most related theories to the shear thickening behavior are the hydrocluster theory. Basically, the hydrocluster will be occurred when the balance force from shearing flow in the concentrated suspension and the force rising from particle particle (interparticles) interaction (Bender and Wagner 1995).There are two conditions, first via colloidal factors (steric and electrostatic repulsion) and particle interactions between particle-particle and particle-carrier fluid (Bender and Wagner 1995). Figure 3 showed the formation of hydrocluster, when the applied shear stress on the STF. The formations of hydrocluster are still extensively investigated by researcher in the entire world. The main interest of this unique behavior is the onset transition (critical shear rate) from liquid state to solid or gel state. This phenomenon involving the rapid changes of fluid viscosity in a second whether applied it with shear stress, applied electric field (refer to the ER fluid), and applied magnetic field (refer to the MR fluid). There are specific equipments for detection of this phenomenon such as optical rheometer, small angle neutron scattering (SANS), and two beam light laser scattering. But with all this equipments, still the formation of hydrocluster is unknown phenomena. According to this theory, at the lower stress (below critical stress, maximum volume packing fraction) interparticle interaction either Brownian motion or electrostatic, making the concentrated suspension is easily flow (shear thinning behavior and viscosity of the suspension become lower) due to the particles slippage in the carrier fluid. As the stress is increased, the attraction forces is slightly increases than repulsion force in between particles of the concentrated suspension (particles aggregation become larger and the viscosity of the suspension become higher). When the magnitudes of the shearing force are equilibrium to the interparticle interaction, the particles in the concentrated suspension become cluster also known as hydrocluster. This theory is first suggested by Brady (Bossis and Brady 1989) as a result from stokesian Dynamics simulation and then, supported by optical rheological experiment by wagner (Bender and Wagner 1995). Basically, these phenomenons are closely related with phenomenon of Resonance in physic. In physics, resonance is the tendency of a system to oscillate at greater amplitude at some frequencies than at others. These are known as the systems resonant frequencies (or resonance frequencies). At these frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores vibration energy [the fundamental of physic 1999]. 2.2.2 Order-Disorder Theory The order-Disorder mechanism is first suggested by Hoffman (Hoffman 1972) which obeserved the monodispersed supension under shear generate different patterns at critical shear rate ( before and after). According to this theory, when the suspension is sheared, particles is ordered in the specific formation ( hexagonal or pentagonal) of packed layers parallel to the plane of shear. After a crtical stress is reached, the instabilities in the formation of packed layers become greater and particles are out of the formation. Then, these particles collide and jammed to each other and produce in the rise of viscosity. An example of these pattern can be seen in figure 4 Hoffman monitored the monodispersed suspension under shear and showed that figure 4(A) corresponds to the order formation of the packed layers while figure 4(B) is disorder or random formation of the packed layers after critical shear stress is reached. The illustration of the phenomenon for the order- disorder formation of the packed layers that suggested by Hoffman can be seen in figure 5. those formation is captured by the Hoffman by using a simple shear in figure 4 (A) is same formation in the figure 5 (A). Hoffman predicted that, those formation occur due to the strong surface bonding in the monodisperse suspension which normally reffered to the hydrogen and van der waals bond. In figure 5 (B), the disorder formation occurs when sample shear above critical shear stress. Particle are collide and jammed each other and produce in rise of viscosity due to the agglomeration of the particles. 2.2.3 Introduction Liquid-Solid Transition (LST) In this paper, a new concept theoretical onset transition of STF will be proposed. The main ideas of this theoretical concept are the macrostructure of the fluid are changes during onset transition from liquid state to the solid or gel state, and liquid- solid transition state which is normally involving the relaxation state (). The transition also can be state as semi-solid transition at the critical shear rate. This paper, also will be investigated the formation of the transition by using colloidal particles which are stabilize by using two system, steric and electrostatic repulsion system. LST involves many such of factors, such as theory of gelation, branching theories, and percolation theories. All the theory in LST are closely related to the formation of the macrostructure, whether effect on the temperature surrounding or over time. 2.2.3.1 Theory of Gelation The LST of polymers is also technically important since it occurs in nearly all of the common fabrication processes. Examples are injection molding of semi-crystalline polymers (where the surface quality of the finished parts may be affected by gelation shear thickening fluid (STF) and processing of crosslinking polymers. Therefore, the onset transition for STF can be detected by using LST. There are several theories in gelation are normally used in LST. First is branching theories and second is percolation theory. The onset transition are very important to the STF for comparison with the hydrocluster formation theories and order disorder theory and proposed new theoretical idea for the rheological behavior due to the factors affecting the performance of STF such as molecular weight dependence, volume fraction dependence and particle particle interaction dependence. Those all factors which affecting the performance of STF had been discussed in previous sub-chapter. 2.2.4 Description of the Phenomena for Shear Thickening Fluid (STF) Basically, the phenomenon of STF is investigated by using a lot of parameter in the last two decades. Volume fraction, particle porosity and interparticle interaction dependence is a major parameters for STF. In this paper, molecular weight of carrier fluid is added in the STFs parameter, in order to increase the potential parameter for the STFs phenomenon. 2.2.4.1 Volume Fraction Dependence Volume fraction factor is the main parameter in the shear thickening fluid [STF]. In general, a solid or hard particle which is suspended in the carrier fluid such as ethylene glycol, polyethylene glycol or other carrier fluid which are aqueous in nature or non-aqueous in nature can exhibit shear thickening behavior at the minimal range of volume fraction in between 30% to 49%. Above 50% of volume fraction, the rheological shear thickening behavior can be measured at lower shear rate but it depending on the complex viscosity of the suspension which is it is related to another parameters like particle size and porosity. Meaning, surface area and aspect ratio of the particle are greater influenced on the final viscosity of the STF. One parameter that has a huge effect on the critical shear rate is the volume fraction. At low volume fractions (below 0.5), shear thickening is either less dramatic or not significant [Characterization of Shear-Thickening Fluid-Filled Foam system for Use in Energy Absorption Devices, Jose 2004]. Wagner and his team also claims, colloidal silica ( 14nm) which is suspended in the polyethylene glycol, less than or 30% volume fraction of STF will producing less or no significant of thickening behavior either at low shear rate or higher. Raghavan and khan which studying the rheological behavior of fumed silica suspended in low molecular weight polypropylene glycol claim, non-flocculated suspension exhibit shear thickening at 10% [w/w] under steady flow and strain-thickening under oscillatory shear. Strain-thickening refer to the abrupt increase in the complex modulus [complex viscosity]. Fumed silica generally known has higher agglomeration size up to 140 micron. Therefore, volume fraction has less significant affected on the shear thickening behavior. The agglomeration size is the main factor in the Raghavan and Khan studies (figure 2.2.4). The results of Barnes demonstrate that at volume fractions in the range of 50 %, the shear thickening behavior is expected and predictable. In addition, theoretical analysis of the maximum volume fraction of monodispersed suspensions predicts this value is ÃËmax=0.605, where this value corresponds to, the volume fraction for a cubically stacked hexagonal packing (Boersma et al. 1989). 2.2.4.2 Molecular Weight of the Carrier Fluid Dependence Molecular weight of the carrier fluid is a new parameter in the STF. Wagner and his team reported that the viscosity of the carrier fluid is important to predict the onset transition from shear thinning to the shear thickening behavior in the STF. A difficulty occurs from getting exacts experimental measurement of the effect of carrier fluids due to the reality that changing the carrier fluid affects the interparticles interaction. In this paper, by monitoring the zeta potential of the carrier fluid, those two effects (molecular weight dependence and Particle-Particle Interaction Dependence) can be separated. The onset transition of STF will be a main indicator for this parameter neither the suspension are flocculated or deflocculated. The idea of used difference molecular weight is cames from colloidal suspension which prepared by raghvan, in his experiment polypropylene glycol (PPG) as a main carrier fluid. He are experimental the effect of the rheological behavior for fumed silica suspended in PPG at lower concentration (mass fraction), and showed the STF behavior at low yield stress (figure 6). The experiment by raghvan is difference from wagner and barnes, which used colloidal particle from Nissan Chemicals (MP4540) and suspended in PEG 200 at high concentration for exhibit shear thicknening behavior (figure 6). Therefore, when turnable fumed silica particle into colloidal fumed silica via steric and electrostatic repulsion system, suspended it in the different molecular weight of carrier fluid at various particle loadings, believed, the suspension will exhibited shear thickening behavior at low yield stress. 2.2.4.3 Particle-Particle Interaction Dependence Interparticles interactions are very important in determining the shear thickening behavior of a suspension. Flocculated suspension will not exhibit shear thickening (Barnes 1989), but instead they will show shear thinning, as shown in figure 7. Basically, the flow behavior of a suspension is extremely affected by interparticle interaction. These phenomenons also refer to the final condition which refers to the pH value of a suspension. Therefore in table 1, the Floc sizes are monitored due to the effect of pH value, electrolytes, and polymer on a kaolin suspension. Because of flocculation is expected to begin at lower pH values, namely edge to face that kaolin is positively charged and de-flocculation at higher pH values it carries a net negative charge on the surface. (Nongkhran Chaiwong 2008). The flocculation of kaolin depended on pH, electrolytes and polymers flocculants. Floc size and floc strength increased with increasing of cation valency in the electrolytes and increasing of molecular weight in the polymers (Nongkhran Chaiwong 2008). The information that gathered from table 1 is important for the colloidal suspension
