She rides with him to a nearby hotel and they engage in sexual activity. When they finish, John hands Jane one hundred dollars and he takes her back to the corner where she had been picked up a few hours earlier. Immoral as some may see it, this was a victimless crime.

Herpes Essay example - 779 Words

Herpes Herpes is one of the common of more than 30 different sexually transmitted diseases (STD’s) in America today. Herpes is an infection that is caused by one of two closely related viruses, herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2). Both of which are very easily caught, have similar symptoms, and can occur on different parts of the body. Even though it is most common to see the virus HSV-1 appear as oral herpes and to see the virus HSV-2 appear as genital herpes. Most often herpes is a relatively harmless disease that is rarely life threatening. The most common form of herpes is oral herpes and usually shows up on the lips or inside of the mouth as â€Å"cold sores† or â€Å"fever blisters†.†¦show more content†¦Very severe outbreaks may have symptoms that include swollen and tender lymph glands in the groin, throat, or under the arms, and even flu-like feelings such as fever, chills, headache, and a general run down feeling. The spread of herpes may be attributed to a variety of activities ranging from touching and kissing to more intimate activities such as vaginal, anal, or oral intercourse. The time when the virus is most likely to be spread is when the sores, such as cold sores or fever blisters, are open and weeping, during this time the virus may be spread from one partner to another or from one part of the body to another. Although the chance of getting genital herpes from an infected partner whom has no symptoms are only about 10 out of every hundred or 10 percent. It is unlikely, however, that contact with toilet seats, moist towels or similar objects spread herpes. The most commonly infected areas are moist areas of the mouth, anus, vulva, vagina, penis, or the eyes. Even though herpes in many cases is easily spread between two individuals, it is definitely possible to prevent the spreading of herpes to others. There are usually early warning signs before a breakout occurs such as tingling, burning, and itching where sores were before.

Battlefield of the Mind Free Essays

â€Å"Battlefield of the Mind: Winning the Battle in Your Mind† Author: Joyce Meyer Reviewer: Lisa Hutson I believe many times in the Christian and especially in the Pentecostal realm, we tend to do things in the name of Christ because we â€Å"felt† like it was from the Holy Spirit and instead of determining that by lining it up with the Bible, the living word of God, we tend to trust that our â€Å"feelings† are correct. But what happens when those feelings steam from negative, confused, judgemental or passive thinking?I never realized until I read this book that the majority of the bad decisions I have made in my life were decisions I made based on present feelings and that those feelings came from faulty or negative thinking. After I read this book, I understood that it is the things that I think about constantly that are the things that soak up my life. We will write a custom essay sample on Battlefield of the Mind or any similar topic only for you Order Now If those thoughts are positive, I will reap positive benefits. If those thoughts are negative, I will reap negativity but it is all in how I think. There are three life lessons that I have learned to incorporate into my daily life in order to live a Christ filled life.When I tend to go through those â€Å"wilderness mentalities†, I have learned to always do my best to be positive, to regularly meditate on the Word of God, and to be thankful at all times. Explaining the importance of being positive, Meyer tells us the mind is a battlefield. After reading 2 Corinthians 10;4,5, Meyer says that we are engaged in a war, our enemy is Satan and that our minds are the battlefield. The devil works diligently to set up strongholds in our mind and he does it through strategy and deceit and that he takes his time to work out his plan (16-17). In order to prevent the devil’s lies from penetrating our minds, we must defend them. You cannot have a positive life and a negative mind. Your life will not get straightened out until your mind does (27-28). Positive minds produce positive lives. Negative minds produce negative lives. Positive thoughts are always full of faith and hope. Negative thoughts are always full of fear and doubt (41). What really struck me about this concept is how Meyer tells us that thinking positive isn’t ignoring the negative, but it is believing that God is bigger than you and your situation and that all things will work together for good as His word promises.I am generally a happy person. I laugh at everything, I like making other people laugh and having good conversations. However, when negative things do arise, I tend to get angry or seclude myself. If I am having a disagreement with a co-worker or an argument with my parents, I will just refuse to talk to them. When the Holy Spirit brings them to my memory, I let negative thoughts produce even more feelings of strife and it takes a long time to get over it. I remember one time last semester when I was so upset with my mother that I refused to talk to her for almost four months!Learning to be positive does not mean that the negative situation did not happen but it simply means that we believe that God will heal it or bring good fro m it. It means forgiving even if we don’t forget but allowing the Holy Spirit to work in our attitudes so that we do not become weighed down by our situations. Meditating on God’s word is another huge lesson I have learned from this book. I believe that my biggest mistake early on in my walk with the Lord was not reading His word for myself. I became a christian at the age of fourteen and filled with the Holy Spirit by the age of sixteen.However, I would rather go on Wednesday nights and hear my youth pastor tell me what the Bible said instead of reading it myself. When I tried to read on my own, I often became very confused and frustrated and gave up. I let other people tell me how to live instead of searching it out myself. I continued this all through high school and finally during my senior year I had a very hurtful situation occur between myself and another family in the church. Since I wasn’t solid in my faith and relationship with the Lord, I let it tear me down significantly and I stayed out the church for about a year and a half.I let another’s faith become my own and when they failed me, I equated that with God failing me. â€Å"This book of the law shall not depart out of your mouth, but you shall meditate on it day and night, that you may observe and do according to all that is written in it. For then you shall make your way prosperous, and then you shall deal wisely and have good success. † Joshua 1:8 The Bible tells us that if we want to be a success and prosper in all of our dealings, we must meditate on the Word of God day and night.The Word of God teaches us what we should spend our time thinking about (57). Meditation in this context means to spend a lot of time pondering and thinking on the ways of God, His instructions and His teachings (57). In my situation, I had let sermons, Sunday school, and people in the church mold my faith and thought process instead of spending time myself thinking about the Word. I thought about the Word while I was sitting in church but outside of that, I had not really let it sink in. Now, I am making a significant effort to seek the scriptures myself.Of course, I am involved in church again but I am also making an effort during my own time to spend quality time with the Lord, in prayer and in His word, allowing Him to mold me into what He has created me to be. The last thing that â€Å"The Battlefield of the Mind† has taught me is to be thankful at all times. How can the devil control us if we are going to be joyful and thankful no matter what our circumstances are? â€Å"I will bless the Lord at all times; His praise shall continually be in my m outh. † Psalm 34:1We can be a blessing to the Lord by letting His praise continually be in our thoughts and mouths (162). Be a grateful person, one filled with gratitude not only toward God, but also toward people (163). Expressing appreciation is not only good for the other person but it is good for us, because it releases joy in us. Meditate daily on all the things you have to be thankful for. Rehearse them to the Lord in prayer, and as you do you will find your heart filling up with life and light (163). During my teenage years, my family went through a financial crisis. We lost our home and our vehicles. I spent my junior year of high school with my parents living out of a garage that we made into a make-shift home. I remembered crying myself to sleep many nights in that garage. I was embarrassed about our situation, angry at my parents for getting us in this mess, and confused that the Lord could let this happen to us. After about fifteen months in that garage, things finally began to turn around. We were able to sell our property and the garage, move into a rental property and get decent vehicles to drive instead of the old sixties model truck my dad had bought for three hundred dollars during the crisis.I remember being so grateful for that new rental property. It was an old yellow brick home, but it was wonderful to me. I had a room with real walls! I spent all of my savings on making my own bedroom beautiful with new paint, picture frames and curtains. It was through that situation that I truly learned how to be grateful. My parents and I have come a long way from that old garage but I still have a picture of that old garage in a frame in my room at home. Sometimes even now, I find myself being selfish and ungrateful for my many blessings.I think everyone does. However, that memory always shows me how far the Lord has brought me and how much farther He can take me as long as I stay faithful. â€Å"Battlefield of the Mind† by Joyce Meyer has many solid lessons that have taught me a lot about how to live victorious in Christ. As a young Pentecostal believer, I always thought everything was spiritually supernatural. If God wanted me to think a certain way, He would just zap it into my head. However, as I grow in my relationship with Him, I realize He is not going to spoon feed me forever.He wants me to seek Him. If I put His lessons and teachings into practice, I will live victoriously. Being positive, meditating on His word and always being thankful to Him and to the people around me are just a few ways I can make my life a living sacrifice to Him. However, its really not even a sacrifice, for the blessings and benefits I receive from these practices far out weight the negatives. I learn more and more about myself and about my Heavenly father as I delve deeper into His word.His word is what empowers my positive attitude and reminds me to be grateful not only for His sacrifice but also for the many blessings He bestows on my life daily. I loved this book. I’m sure I will keep it around to read occasionally and remind myself to get my mind in order! Thinking produces feelings and feelings behaviors and if I’m not happy with any certain behaviors, I must stem it back to what I spend my time thinking about. My mind is the battlefield and when it is renewed in Christ, I will be able to battle the enemy with confidence, perseverance, and power. How to cite Battlefield of the Mind, Papers

What Is The Nature And Substance Of Organisational Culture To What Ex

What Is The Nature And Substance Of Organisational Culture? To What Extent Can It Be Changed? Culture, the acquired knowledge that people use to interpret experience and generate social behaviour (Spradley, 1979, p. 5), provides people with a way of seeing the world. It categorizes, encodes, and otherwise defines the world in which they live. Whenever people learn a culture, they are to some extent imprisoned without knowing it. Anthropologists talk of this as being culture bound--i.e., living inside a particular reality. References to culture have long abounded in professional literature. However, it is only fairly recently that the literature shows references to culture as a lens through which to interpret and understand organizations, their customers, and the working relationships therein (Lee Shaughnessy, 1988). The cultural analysis of organizations, therefore, is the use of organizational culture as a lens through which to examine what is going on in an organization. Management theory in the 1980s underwent a sea of change in its realization that an understanding of an organization's culture(s) could be a major step on the road to changing or controlling the direction of that organization. There are both positive and negative sides to how an understanding of culture can be used within an organization. For instance, Edgar Schein (1992) considers the process of creating culture and management to be the essence of leadership, while Gideon Kunda (1992) describes a culture which embodies both the implicit and explicit rules and behaviour of a particular group of people and the conscious efforts of management to engineer the culture to its own goals. There is a fundamental distinction between those who think of culture as a metaphor (Morgan, 1986) and those who see culture as an objective entity. (Gold 1982) Metaphors allow us to understand organisations in terms of other complex entities such as the machine and the organism. By observing the similarities, scholars attempt to explain the essence of human organisations. The dangers of such an approach is distinguishing when the metaphor is no longer valid. That is why most commentators have chosen to think of culture as an objective entity. This view have ranged from viewing the organisation literally as a culture with all features of an organisations including its systems, policies procedures and processes as elements of its cultural life (Paconowsky & O'Donnell-Trujillo 1982) to suggesting that culture is best thought of as a set of psychological predispositions, called ?basic assumptions', that members of an organisation possess that leads them to think and act in a certain way .(Schein 1985). The former view presents problems in using the concept to explain other aspects of organisational activity. Indeed if everything is culture, this view becomes indistinguishable from the view that culture is a metaphor. This leaves us with Schein's view of culture as an essentially cognitive phenomena that resides in the psychology of organisational participants, with the acknowledgement that patterns of behaviour are equally important (Eldridge & Crombie 1974) The contents of an organisational culture has several levels. At the basic and superficial level, it takes the form of artefacts like stories, jokes metaphors and symbols. Examples of artefacts would be Material objects like mission statements, corporate logos , Physical layout of the office space etc. At a deeper level, culture takes the form of values beliefs and attitudes. Values determine what people ought to do while beliefs are what people think is or is not true. In practice, beliefs and values are often hard to distinguish, because beliefs frequently involve values. Moreover, there is considerable merit to viewing values as a particular sort of belief. (Rokeach 1973: 5) Attitudes connect beliefs and values with feelings. An attitude is a learned predisposition to respond consistently to a particular thing or idea. Attitudes are developed over time and unlike opinions, are held relatively consistently. At the deepest level, culture in an organisation takes the form of basic assumptions, a solution to an identifiable problem that is taken for granted. These are implicit, deep-rooted assumptions that people share, and which guides their perception, feelings and emotions about things. (Schein, 1981) Basic assumptions are held unconsciously and are very difficult to surface. Basic assumptions are by definition neither confront able nor debatable. Basic assumptions are also

Atomism - Pre-Socratic Philosophy

Atomism - Pre-Socratic Philosophy Atomism: Atomism was one of the theories the ancient Greek natural philosophers devised to explain the universe. The atoms, from the Greek for not cut were indivisible. They had few innate properties (size, shape, order, and position) and could hit each other in the void. By hitting one another and locking together, they become something else. This philosophy explained the material of the universe and is called a materialist philosophy. Atomists also developed ethics, epistemology, and political philosophy based on atomism. Leucippus and Democritus: Leucippus (c. 480 - c. 420 B.C.) is credited with coming up with atomism, although sometimes this credit is extended equally to Democritus of Abdera, the other main early atomist. Another (earlier) candidate is Moschus of Sidon, from the Trojan War era. Leucippus and Democritus (460-370 B.C.) posited that the natural world is comprised of only two, indivisible bodies, the void, and atoms. Atoms continually bounce around in the void, bouncing into each other, but eventually bouncing off. This movement explains how things change. The Motivation for Atomism: Aristotle (384-322 B.C.) wrote that the idea of indivisible bodies came in response to the teaching of another Pre-Socratic philosopher, Parmenides, who said that the very fact of change implies that something that is not either really is or comes into being from nothing. The atomists are also thought to have been countering the paradoxes of Zeno, who argued that if objects can be infinitely divided, then the motion should be impossible because otherwise, a body would have to cover an infinite number of spaces in a finite amount of time. Perception: The atomists believed we see objects because a film of atoms drops off the surface of the objects we see. The color is produced by the position of these atoms. Early atomists thought perceptions exist by convention, while atoms and the void exist by reality. Later atomists rejected this distinction. Epicurus: A few hundred years after Democritus, the Hellenistic era revived the atomist philosophy. Epicureans (341-270 B.C.) formed a community applying atomism to a philosophy of living a pleasant life. Their community included women and some women raised children there. Epicureans sought pleasure by getting rid of things like fear. Fear of gods and death are inconsistent with atomism and if we can get rid of them, we will be free of mental anguish.

(Lewis, S. & Lewis, 2005) The roles of tactician, technical guru, and human resources leader receives middle rankings while commander, servant, dictator, king or queen receive the lowest ranking for effective IT leaders. Congruent with this ranking of roles for effective IT leaders, team building is considered the most important function, followed by management, then creating. Leadership in Information Technology in Private Industry When the inf ormation technological skills of leadership are combined with an ability to use software to solve IT problems as in Acorn Computer City, New York, leaders of the organization are better equipped to move among the various agencies comprising our society. It was assessed whether leaders of IT firm can be trained, what characteristics are important for IT leaders of the organization, and what is the best environment to encourage IT leadership. While strategic leadership is possible at all levels within the organization, there is a need for work on leadership at the project leader/project manager level. As Sear (2008) pointed out, IT leaders have a difficult time making the transition from skilled technical work to project leader. Not only are they better able to use software to manage their... The concept of communication with a physician via e-mail is not really a future capability; it is available now and used to a very limited extent. What stands in the way of its widespread use is not the absence of cutting-edge communication technology, but rather a broken payment system. Physicians are paid relatively well for procedures, relatively poorly for office visits, and not at all for telephone or e-mail advice. Increasing the bandwidth for patients without fixing reimbursement is more likely to lead to a future state where frustrated patients complain, "My doctor doesn't return my phone calls or answer my e-mail." One of the more contentious but critically important issues today is the so-called misalignment of the costs and benefits of health IT. Essentially, the argument is that under our current fragmented healthcare system, physicians and hospitals pay for IT, and most of the benefit flows to payers. The Center for Information Technology Leadership modeled the cost and benefit of an ambulatory computerized physician order entry system, and concluded that 89 percent of the benefit accrued to payers, with only 11 percent flowing to providers (Johnston et al. 2003). Nelson references the landmark Wang study, which looked at system benefits of an advanced EHR in an office practice. Wang concluded that primarily by reducing pharmacy expenditures and avoiding redundant testing, payers would save about $86,000 per physician over five years-thus making the first real economic argument for payers funding EHRs for physicians.

Women's Suffrage Research Paper Example | Topics and Well Written Essays - 1750 words

Women's Suffrage - Research Paper Example Women’s suffrage also encompasses political as well as economic rights to women who then qualify without any restriction to payment of taxes, ownership of property and marital status. Following the 1907 elections, the Grand Duchy of Finland was the first country to produce the first female as a member of parliament. In the United States, women’s suffrage gradually infiltrated the local and the states politics in the 19th and 20th century. In 1920, this movement culminated with the passage of Nineteenth Amendment to the Constitution of USA (Du Bois 77). This paper seeks to explore the opinion of three scholars on Women’s suffrage. Scholars’ Opinions William Du Bois (1868-1963) was a chief advocator for the civil rights of the Black society. In addition, he showed continued interest on the question of women and their rights to vote through his writing. He wrote the Horizons, Voice of the Negros and The independent where he advocated for the rights of the Afr o-Americans as well as women in the society (Du Bois 75). During his time, he described various issues that affected the women in the Negro society. He undertook various factual studies to analyze the employment, wages, working hours and working conditions of women as compared to those of men. He noticed that there was sex discrimination in the job opportunities, wages as well as working conditions, which favored the men. He also reported that the black woman faced sexist discrimination in the society. They also faced racial discrimination that was practiced by the women organizations. During an annual convention of the National American Women Suffrage Association, he delivered a speech on suffrage that was later published as a book. During this speech, he advocated for the women’s right and encouraged their fight for justice. Furthermore, he collaborated with several famous suffragists, for example, Jane Addams, Mary Church Terrel and Ida Wells (McGoldrick 1). Du Bios throug h his writing has been acknowledged as a supporter for the woman suffrage by various scholars. During his tenure in the National Association of Advancement of Colored People (NAACP), he used his position as the editor of The Crisis magazine to champion the rights of women. In 1912, 1915 and 1917, he dedicated these editions on Women’s suffrage (Du Bois 76). In The Crisis of 1912, he suggested that the alliance between women and the African American should be continued in the 20th century. This edition of the article carried Fredrick Douglass portrait as the cover. The cover image was contrary to the message inside the magazine. This was because Fredrick Douglass was strongly against women’s suffrage (McGoldrick 1). In this edition, Du Bois termed the demand for the women’s suffrage as a significant human question that should not be ignored by any black citizen in the world. This openly criticized F. Douglass’s campaign against women’s suffrage. In 1915, the cover magazine carried the portrait of Abraham Lincoln and Sojourner Truth. They were black leaders who fought for the liberalization of the Black people. In this edition, Du Bois reminded his readers of the obvious historical linkage between women and African Americans. This edition contained comments from twenty black women and men on women’s suffrage. The edition reflected the African American views concerning the issue. Later on, in 1917 he dedicated the last edition which was released on the eve of enfranchisement of African Americans, which took place in New York (McGoldrick 1). In this edition, he encouraged the black women to get ready to vote. This edition served to give hope to the Black women that they should prepare to be

The Film Essay Example | Topics and Well Written Essays - 1500 words

The Film - Essay Example Adopting a light-hearted tone, Marker takes the unique approach of editing various video clips together, without adhering to time frame, and putting them together to describe the memories of the fictional Sandor Krasna, whose letters are read by a female narrator whose identity we never find out. Resnais’ Nuit et Brouillard, on the other hand, is based on the very real and macabre events of Holocaust. With most of the focus on the notorious Auschwitz concentration camp, the documentary which was filmed ten years after the Holocaust ended (1955), lays bare the atrocities committed therein. The male narrator simply relates the series of events that start from the rounding up of the people who were being sent to the concentration camps. The tone of the movie is, of course, very somber and serious throughout. In his movie, Chris Marker tries to explore how human memory works and how time and place have an effect on everything that later becomes history. It is an attempt on his part to take an interest in the banalities of life and, through them, try to explain human nature. The tone of the movie remains quite philosophical; though a lot of people are put off by it and they claim that Marker has ruined what could have otherwise been a great travelogue by using this tone, I disagree. The script of the movie, which are the letters read by the narrator, is crisp, innovative and it helps in driving the point home: the subjectivity of human memory and how we perceive time. It is a very unique approach and I agree that it is not palatable to everyone; however, it is unfair on the part of the critics to call it a work of pseudo-intellectualism. In Nuit et Brouillard, the script is very objective and it portrays the suffering of the prisoners of concentration camps in Nazi Germany. There are no personal observations made by the narrator; he recounts the events as and when

Acid Leaching for Metallic Impurities

Acid Leaching for Metallic Impurities Acid Leaching for Metallic Impurities Evaluation of Some Mineral Ores in Nigeria *R.L. Tyohemba1 S. K. Emgba2 Abstract There is every need to access the impurity ratio of mineral ores in order to furnish investors and industrialists with information required to weigh the gains of venturing into their exploration. Metallic ores including; Zinc ore (Sphalerite), Iron ore (Magnetite), Iron ore (Heamatite), Copper ore (chalcocite), Lead ore (Galena) and gypsum were obtained from the National Geological Survey Kaduna. The ore samples were grounded and digested with aqua regia solution to leach their metallic constituents using standard method. The main metallic components of the ores viz: Zn, Fe, Cu, Pb and Ca were determined by the flame atomic absorption spectrophotometer (Biotech FAAS Phoenix 986) alongside their associated impurities. Galena (Lead ore) recorded the highest metallic impurity content of about 28.64 % and was followed by Sphalerite with about 6.31 % metallic impurities. The other ores recorded Zn>Mg>Ni>Pb. The impurity content of heamatite and magnetite were of the same trend in the orde r Mn>Cu>Zn>Ni>Pb. However, heamatite recorded higher Fe content than magnetite. Galena contained 534.50 mg/Kg (71.36 %) lead content with its associated impurities present in the order Zn>Mn>Cu>Cd. Sphalerite contained 8362.22 mg/Kg (93.69 %) as zinc while its associated impurities were present in the order of Cu>Fe>Ca>Mn>Pb. In gypsum, its Calcium content was (97.15 %) with its associated metallic impurities in the order Mg>Fe>K>Cr>Pb. The studied ores had a very high level of their major metallic constituents with only Galena which had a high level of impurities. Thus these ores could be good feedstock to mine their principal components. 1.1 INTRODUCTION Nigeria is richly endowed with a variety of mineral resources, fossil fuelsand solid minerals ranging from precious metals, various stones to industrial minerals such as Lead(Pb), Feldspar(xAl(Al,Si)3O8), ron magnetite(Fe3O4), iron hematite(Fe2O3), gypsum(CaSO4.2H2O),copper(Cu), Kaolinite(Al2O5(OH)4Si), Zinc(Zn), Limestone(caco3) e. t. c. Most of these are yet to be exploited. Statistically, the level of exploitation of these minerals is very low in relation to the extent of deposits found in the country. The presence of impurities in ores is inevitable due the nature of their occurrence. Impurities in minerals may be caused by simple admixtures or by crystal chemical substitutions [1]. Impurities are often responsible for colour changes. Natural impurities are common in minerals, as is the propensity for one element to slip into the crystalline structure in place of some other element. Exchanges of these forms do not cause a modification in mineral name as long as the replacements m ake up only a small proportion of the entire structure. Oxides nodules of Ni, Co and Cu have been found to occur in lattices of iron and manganese [2]. Associated impurities of zinc(II) such as lead, iron, Copper, Silver etc., contained in are said to be found present in Nigerian sphalerite mineral[3]. The high manganese content of the sphaleritesleave them incongruous for processing by conventional smeltingtechniques, facilitating the inevitability to design and construct an onsiterefinery that is specifically suited for Gamsberg ores and concentrates [4]. Naturally occurringsphalerite commonly incorporates variable concentrations ofimpurities (e.g. Fe, Cd, Mn, Cu, Co, Ni, Ge, In) that substitute zincin lattice sites. For example, FeS concentrations can range up to25 mol. %, while MnSseldom reaches up to 14 mol.%. Consequently,the high extent of stoichiometric inconsistency observedhas a marked effect on the processing, as high levels of theseimpurities in some zinc concentrates, i.e. Gamsberg, renders themunsuitable for processing by tr aditional operations.Copper is associated with basemetals such as nickel and cobalt. Studies have also been carried out on representative samples of Kà ¼re (Turkey) where massive rich copper ore were leached in acidic ferric sulfate solutions in order to recover copper and its associated metals (Zn, Co, Ni) present in the ore[5].The minerals of lead and zinc are naturally associated with eachOther.In many parts of the world, significant deposits of these mixedsulphide–oxide lead and zinc ores are found with the main sulphideand/or oxidised ore bodies. Because of their complex mineralogy,these ores are very difficult to deal with from a mineral processingpoint of view and they are very often left untreated as a result of themetallurgical difficulties encountered in extracting lead and zincfrom them. Although the primary sources of the metals are leadand zinc concentrates from sulphide and oxidised ores, as suppliesof these deplete, the processing of mixed ores must be considered[6]. Also, the lead-zinc ore from a mine is featured by complicated copper-lead-zin c intergrowth and uneven dissemination size. Besides, the minerals containing copper activate by nature the mineral containing zinc, causing difficulty of separation of copper, lead and zinc minerals [7].There also published data on the presence of metallic impurities including; Fe, Se, Mg, Al, Si, Cu, Zn, Pb, Cr, La, Ce, Nd and Y which were removed from desulpurized gypsum [8]. Hayward and Quincy [9] developed a method for the treatment of iron ores containing impurities such as aluminium, silicon, chromium, nickel and cobalt from iron ores of the type which contain nickel in excess of 0.25% and chromium in excess of 0.5%, such as for example those ores found in Cuba known as Mayari ores. The impurities which are present in all iron ores such as sulphur, phosphorus, manganese and silicon appear in iron and steel made there from. Such impurities are generally undesirable in iron alloys, but it has not been possible to remove them completely, and only high grade iron ores are used at present in the production of iron. For this reason, various low grade iron ores have been wholly rejected, either because of their high contents of the impurities mentioned or because they contain varying amounts of base metals [10]. These bulks of impurities mentioned in the essay have obvious unattractive characteristics that will increase the cost of mineral processing. There exist speculations that mineral ores in Nigeria are characterized by high levels of impurities. It then becomes imperative to access these mineral ores and their impurity ratios to furnish investors and industrialists with information that will help to estimate cost of production as well as to find suitable methods applicable for their purification. 2.1 METHODOLOGY 2.1.1 Sample Collection and Preparation Mineral ores including; Zinc ore (Sphalerite ZnS), Iron ore (Magnetite – Fe3O4), Iron ore (Heamatite (Fe2O3)), Copper ore (chalcocite Cu2S)), and Lead (Galena-PbS) were obtained from the National Geological Survey Kaduna. The samples were stored in the laboratory for the study. The ore samples were grounded using a porcelain mortar and pistol sieved and digested to leach their metallic constituents using the procedure described below. 2.1.2 Acid leaching of ore samples for metallic content determination. This was carried out as described by the ISO (1998)procedure [11]. 1g of the grounded air dried ore sample was transferred into a 250 ml reaction vessel (Teflon digestion bomb). 10ml of the mixture of nitric acid and hydrochloric acid in a ration of 1:3 (aqua regia) was added unto the reaction vessel containing 1g of dried sample and heated using hot plate inside a fume hood until white fume was observed and allowed to cool. The reaction vessel was allowed to stand so that most of any insoluble residue settles out of suspension. The relatively sediment-free extract was decanted carefully onto a filter paper, collecting the filtrate in a 100 ml volumetric flask. All the initial filtrate was allowed to pass through the filter paper, and the insoluble residue was washed onto the filter paper with a minimum amount of nitric acid (0.5 mol/l). The filtrate so collected was collected alongside the initial filtrate and the volume of the flask was made up to mark with deionized water. The extract thus prepared was ready for the determination of the studied metals, by an atomic absorption spectrometer (Biotech FAAS Phoenix 986). 3.1 RESULTS AND DISCUSSION 3.1.1 Metallic Content of Copper Ore (Chalcocite). The result of metallic content of copper ore is presented in table 1. The concentration of copper in the ore was found to be 10341.73 (mgkg-1) representing about 97.7% of its metallic content covered by this work. Other metallic constituents which are considered to be impurities were also found present. Hence, Ca (99.65 (mgkg-1), Mg (63.89 mgkg-1), Ni (9.38 mgkg-1), Pb (1.99 mgkg-1) and Zn (73.26 mgkg-1) in the order Ca>Zn>Mg>Ni>Pb. These metallic ions exists in their +2 oxidation states as copper and could replace the Cu2+ in its lattice sites. In a similar work by [5], massive rich copper ore was leached in acidic ferric sulphate solutions and was able to recover copper and its associated metals (Zn, Co and Ni). Table 1 Metallic content of Copper ore (mg/Kg) 3.1. 2. Metallic content of the studied Iron ores (Heamatite and Magnetite) Presented in table 2 are the available metallic contents of the studied iron ores. The mount of iron in the heamatite ore was found to be 6488.19 mgkg-1, representing (97.3) % of the total metallic content evaluated in the study. The iron content of magnetite was 5571.81 mgkg-1, representing 96.99%. However, an interesting trend was observed in the variation in the amount of metallic impurities which were found present in these iron ores. Both heamatite and magnetite varied in their level of impurities in the order Mn>Cu>Zn>Ni>Pb. Oxides nodules of Ni, Co and Cu have been found elsewhere to occur in lattices of iron and manganese ores [2]. Hayward and Quincy [9] had already identified impurities such as Aluminium, Silicon, Chromium, Nickel and cobalt from iron ores of the type which contained nickel in excess of 0.25%. The values reported in this study for both iron ores are lower in nickel content than those recorded above (0.21 and 0.18) % nickel for heamatite and magnetite respect ively. As earlier stated in literature, iron alloys are generally undesirable but it has not been possible to remove them completely, and only high grade iron ores are used at present in the production of iron. For this reason, various low grade iron ores have been wholly rejected, either because of their high contents of the impurities mentioned or because they contain varying amounts of base metals [10]. From the results presented in this study, Nigerian iron ores are of high iron content with very minimal impurity content in the ratio of (1:35 and 1:32) iron to metallic impurities content of heamatite and magnetite. Table 2 Metallic content of iron ores (HeamatiteMagnetite) (mg/Kg) **H: Heamatite **M: Magnetite 3.1. 3 Metallic Content of Lead Ore (Galena) The recorded amount of Pb in the galena ore was 534.50 mgkg-1, representing (71.36) % Pb content of the studied metallic components. Also, other metallic components considered to be impurities including; Cadmium, Copper, Manganese and Zinc were found present in the ore as presented in table 4 in the order Zn>Mn>Cu>Cd. The metallic impurities of Zn and Mn were present in relatively large amounts. (i.e. 14.21 and 12.85) %. The minerals of Lead and zinc are naturally associated with each other. In many parts of the world, significant deposits of these mixed sulphide-oxide lead and zinc ores are found with the main sulphide and/or oxidized ore bodies. Because of their complex mineralogy, these are very difficult to deal with from mineral processing point of view and they are very often left untreated as a result of the metallurgical difficulties encountered in extracting lead and zinc from them [6]. Table 4. Metallic content of Lead ore (mg/Kg) 3.1.4 Metallic Content of Zinc ore(Sphalerite) The results are found in table 5. Zinc content was determined to be 8362.22 mgkg-1 (93.69) % of the ore’s metallic content studied. Other metallic components which are considered to be common impurities associated with zinc ores were also found present in the other Cu>Fe>Ca>Mn>Pb. The occurrence of zinc with such impurities has earlier been reported in the previous session. Table 5. Metallic content of Zinc ore (mg/Kg) 3.1.5 Metallic content of gypsum Heiska (2011) have reported the presence of metallic impurities including; Fe, Se, Mg, Al, Si, Cu, Zn, Pb, Cr, La, Ce, Nd and Y in gypsum. As presented in table 6, the main metallic component of gypsum which is calcium was evaluated to be 9921.03 mgkg-1, representing 97.15 % of the total metallic content of the studied metals. Other metals such as Cr, Fe, Mg, K and Pb were found present in the acid leached mineral in the order Mg>Fe>K>Cr>Pb. The dominance of Mg as an impurity in this ore is much expected as the metal ion (Mg2+) is known to occur in areas where there calcium deposits exchanging at its lattice and together causing water hardness. Table 6. Metallic content of Gypsum ore (mg/Kg) 3.1.6 Main metal component and impurities ratios of studied ores In table 7 and fig. 2, the summary of these ratios are presented. Lead ore had the highest level of total metallic impurities recording about 28.69 % as impurities in its ore. Others had low metallic impurities in them. Zinc ore recorded less than 10 % as metallic impurities. On the other hand, metallic impurities in copper, heamatite, magnetite and gypsum were less than 5 %. Table 7.Metal/metallic impurity ratios of studied ores. Fig.2 Metal/metallic impurity ratios of studied ores 4.1. Conclusion The analysis of metallic content of some of the Nigerian mineral ores presented from the result indicates that the studied metallic ores are rich in their principal metallic constituent. The only exception observed is the high impurity content of galena (Lead ore). All the other mineral ores had a little percentage of metallic impurities in them. It is gain saying that these raw materials could serve as very rich industrial feedstock that will require little processing and thus serve cost. The high Zinc and Manganese content of the galena is disadvantageous in terms of the metallurgical process that will be required to recover the major metallic content as well as the appreciable contents of the other metals which are equally of industrial importance.

A Comparison of Love in Annabel Lee and La Belle Dame sans Merci Essay

Love in Poe’s Annabel Lee and Keats’s La Belle Dame sans Merci  Ã‚     Ã‚   Poe’s â€Å"Annabel Lee" and Keats’s "La Belle Dame sans Merci" depict the destructive effects that women exercise upon men. In both poems, women, by death and deception, harm their adoring lovers. In "Annabel Lee," Annabel dies and leaves the speaker in isolation; in "La Belle Dame Sans Merci," the fairy, "La Belle Dame," captures the speaker’s heart, and then deserts him. The common theme of both poems, that love generates harmful effects, is a reflection of both poets’ upsetting and harmful childhood experiences. Poetry, Keats purports, "comes from the ferment of an unhappy childhood working through a noble imagination" (Keats 16). The "lesson of [Keat’s] boyhood" was that "the intensity of the beauty, the joy, the pleasure, and the bitterness of their loss" is "necessary for a poem" (Keats 17). The deaths of [Poe’s] parents, foster mother, and wife develop a similar intensity in the form of a "lingering pity and sorrow for the dead" (Whitman 61). The implied malevolence in "Annabel Lee" and "La Belle Dame sans Merci" echoes these poets’ pasts; the poems’ speakers are unable to live sanely or comfortably after experiencing and then losing the objects of their exquisite affection. Furthermore, the speaker’s names are concealed, stressing the importance of the women over the speakers. While both poets believe that love creates destructive situations, they differ about most damaging kind of love. Poe believed that an innocent and sexless love hurt the greatest: his speaker went insane from "love that was more than love," while he and his lover were "child[ren]." Poe’s "aesthetic religion" was a "worship of the beautiful†¦in all noble thoughts, in all ho... ...a Belle Dame sans Merci" through their "fascination with the doomed nature of love" (De Reyes 107).    Works Cited Allen, Hervey.

Pandora: disintermediator or disintermediated? Essay

For Pandora, one of the biggest players in Internet radio, figuring out the future is both challenging and intimidating. If the regular challenges of growing a new company aren’t enough, Pandora also faces a market that is reeling in turmoil. In the new digital world, the way people listen to music continues to change dramatically. It seems likely that Pandora will either lead the changes or fall victim to them. Pandora was founded just over a decade ago. At that time, a vast majority of music listeners were still getting their groove on in one of two ways: They either popped a CD into their home, car, or personal CD player or they turned on the old AM/FM radio. But the advent of digital formats like MP3s has had a huge impact on CD sales and has drawn people away from what is now called â€Å"terrestrial radio.† Moreover, like the music business, the radio business has faced major changes of its own. The Telecommunications Act of 1996 reduced limitations on the number of stations that one owner could hold. This led to huge ownership groups that consolidated and standardized listening formats. The result is less diversity on the radio, with shorter playlists and fewer artists represented. From one city to the next, all across the United States, radio stations have started to sound more alike. Both these trends – combined with the explosion of Internet usage and changes in online technologies – have led to a deluge of companies trying to capitalize on the future of music distribution. This includes download services such as iTunes, subscription services such as Rhapsody and eMusic, an endless number of Internet radio stations, and even satellite   radio network SirriusXM. Today, with an ever†growing list of listening devices and cloud music services that store personal music libraries so they can be accessed anywhere by any device, listening trends continue to evolve. But one thing about the future is certain: The business of listening to music is full of disruption and confusion. Things are changing fast and the winning products and services—indeed, the survivors—are yet to be determined. The Power of People Amid the chaos, Pandora has carved out its own niche, setting itself apart as an automated music recommendation service. It isn’t a play†on†demand service, where members can simply choose the exact song and artist they want. Rather, listeners enter an artist or song suggestion. The playlist starts with a track by the r equested artist and inserts additional songs by that artist every once in a while. But in between, Pandora cues up songs by other artists similar in nature to the requested material. If an unliked or unwanted song plays, the listener can click the â€Å"thumbs down† icon or just skip the song and it will be removed from the list. Users can also create stations by browsing artists alphabetically, or they can tune in to pre†made genre stations or to other users’ stations. Listener’s can create as many stations as they wish, each oriented around the initial input. Lots of online services employ similar recommendation features (think Netflix and Amazon). But Pandora has set a precedent by the predictive power of its recommendation software. The Pandora software is amazingly precise at choosing material that fits with what the user wants. According to Tim Westergren, founder and Chief Strategy Officer for Pandora,

Political and Legal, Cultural and Social in Maldives Essays

Political and Legal, Cultural and Social in Maldives Essays Political and Legal, Cultural and Social in Maldives Essay Political and Legal, Cultural and Social in Maldives Essay Cultural and Social Maldives is a beautiful island in the Indian Ocean that makes it the smallest country in the world population wise that attracts many tourists all year round. Maldives offers a wide variety of water activities such as surfboarding, diving and most importantly, snorkelling. The potential group of customers would be the younger aged tourists. Before the business expands their business there, they must look at a few aspects. Firstly, the language that is used in Maldives. Common language used in Maldives is Dhivehi and English.So, it is not a problem for the business to expand their business, as the language barrier is not an issue. If the Maldivians do not understand English, the business will have to find a translator to translate the message is trying to convey to them. The business should be mindful not to use product names that are offensive because some words bring different meanings in different countries. Next is the religion of Maldivians. Islam has embraced in Maldives since the year 1153. As of late, almost all the Maldivians are Muslim. The business have to take into consideration the ‘Halal and Haram’ in Islam.The business must bear with the Maldivians during Ramadan season because they cannot participate in water activities during that period of time. They must know that they will make loses during the period of time because the Maldivians will not play surfboarding during the period of time. Other than that, the business has to consider the social and norms of the people in Maldives. Large amount of people in Maldives are Muslim, therefore they have different social values and norms. The acceptance of the business’s products or service highly depends on the people in Maldives.If they do not purchase the products, the business will not make any profits therefore, the business faces a huge problem where they will have to close down their business. Political and Legal The business must consider the attitudes of M aldivians towards foreign products. Some consumers will think that the products from certain countries are of inferior quality. Therefore, they will not purchase the products. In order to solve the problem, the business must maintain as a professional business and advertise their products widely in order to gain the customers.The acceptance of the business’s products or service highly depends on the people in Maldives. If they do not purchase the products, the business will not make any profits which means the business is facing a huge problem where they will have to close down their business. The business has to make sure that no one will bad mouth about their products and services as it will strongly influence other customers decision to purchase the products or not. The politics of the Maldives take place in the paradigm of a presidential representative democratic republic, whereby the President is the Head of Government.The government runs the executive power. The Preside nt is the head of the executive branch and assigns the Cabinet. Like many presidential democracies, each member of the cabinet needs to be authorised by the Parliament. The President, alongside the Vice President, is elected by the people to a five-year term through a secret ballot system. However if the President runs again, he could be elected to a second five-year term if that limit is permitted by the Constitution. The business has to focus on their resolution of disputes with Maldives too.If the business does not solve the problem, the Maldivians will probably stop trading with them. Therefore, communication is one of the most important parts in resolving arguments or disagreements. To resolve the problem in a proper way, the business should build a Resolution Centre. The negotiation custom between the business and the Maldivians. In Maldives, the ranking and greeting process is quite important. The Maldivians respect each other. The business should greet them and respect them before expanding their business to Maldives. Hand shaking is also one of the common greetings.

The Domestication of Horses

The Domestication of Horses Domestication is the process by which humans take wild species and acclimatize them to breeding and surviving in captivity. In many cases, domesticated animals serve some purpose for humans (food source, labor, companionship). The process of domestication results in physiological and genetic changes in the organisms over generations. Domestication differs from taming in that tamed animals are born in the wild while domesticated animals are bred in captivity. When Where Were Horses Domesticated? The history of horses in human culture can be traced back as far as 30,000 BC when horses were depicted in Paleolithic cave paintings. The horses in the paintings resembled wild animals and it is thought that true domestication of horses did not occur for tens of thousands of years to come. It is thought that the horses depicted in the Paleolithic cave paintings were hunted for their meat by humans. There are several theories as to when and where domestication of the horse occurred. Some theories estimate that domestication occurred at about 2000 BC while other theories place domestication as early as 4500 BC. Evidence from mitochondrial DNA studies suggests that the domestication of horses occurred in multiple locations and at various times. It is generally thought that Central Asia is among the sites that domestication occurred, with sites in Ukraine and Kazakhstan providing archeological evidence. What Role Did the First Domesticated Horses Play? Throughout history, horses have been used for riding and for pulling carriages, chariots, plows, and carts. They played a significant role in warfare by carrying soldiers into battle. Because the first domesticated horses are thought to have been quite small, it is more likely that they were used to pull carts than for riding.

Current event article and synopsis about obama care

Current event and synopsis about obama care - Article Example White House spokesman Jay Carney downplayed the CBO report, arguing that â€Å"CBO does not take into account positive impacts on worker productivity due to the ACAs role in improving workers health, including reduced absenteeism.† But there is no worker as unproductive or as absent as the one who works less on purpose because a small increase in pay could suddenly deprive him or her of a large Obamacare subsidy. One White House adviser tried to defend this as creating new â€Å"options† for workers, but this is an ad hoc defense, forced on Obama as an unintended and unwelcome consequence of his health care law. Obamacares disincentive to work directly contradicts Obamas consistent philosophy of work - something he began articulating as long as a decade ago and which he has restated as recently as last weeks State of the Union address. Obamas philosophy is an orthodox liberal one, but it starts with premises most conservatives would embrace. In his 2006 memoir The Audacity of Hope, he extolled the virtues of â€Å"self-reliance," "self-improvement," "drive," "discipline," "temperance," "hard work," "thrift" and "personal responsibility.† Then he added the punch line: â€Å"The legitimacy of our government and our economy depend on the degree to which these values are rewarded.† In a passage that specifically criticizes the perverse incentives of the welfare state, Obama wrote that â€Å"Americans believe in work — not just as a means of supporting themselves but as a means of giving their lives purpose and direction, order and dignity †¦ Americans also believe that if we work full-time, we should be able to support ourselves and our kids. For many people on the bottom rungs of the economy — mainly low-skilled workers in the rapidly growing service sector — this basic promise isn’t being fulfilled.† In short, Obama appeals to the work ethic as something government and all employers have a societal obligation to reward. This echoes in the argument

Personal skills and self-management Assignment Example | Topics and Well Written Essays - 1250 words

Personal skills and self-management - Assignment Example The new initiative is the work of the ANZ Mortgages that entails implementing a policy requesting the non-issuance of Certificate of Titles for all the mortgages which are registered by the ANZ Bank in Western Australia. The purpose of this project is to eliminate the issuance of duplicate Titles to the bank by the Titles office. This initiative is supposed to be implemented and running in the next three months. The initiative stakeholders will involve several groups among them, customers, solicitors and a government department. This initiative will be facilitated by technology as it will reduce costs and improve service efficiency. Planning of a new project or initiative is usually difficult as many people are usually against the idea because of the perceived change of status quo. To make sure a move successful it is important to talk to all the parties involved of the benefits of such a project and the likely effects that such a project would have on them or their day to day operat ions. The management may also be sceptical of the idea because of the costs involved in setting up such projects. During planning the project goals need to be identified, the project deliverables need to be set, the time frame and the supporting plans need to be established in order to make the project successful. This project is relevant as it will reduce unnecessary paper work and procedures involved in keeping of duplicate titles at the titles office (Haugan, 2002, 2-39). Once the project is identified by the management or proposed by the staff as was the case for this initiative, a major decision process often begins. Several decisions have to be made whether the project should be implemented or not. In the decision making process a variety of things are involved. In this project a decision needs to be made whether this initiative is actually beneficial to the organization or not. It will be of no benefit if a project was begun which does not add value to the organization. The o bjective of this project as explained above is to eliminate the issuing of Duplicate Titles to the bank by the titles office. The current procedure at the Bank is that when taking security over landed assets in the form of a first registered mortgage, the client is supposed to deliver a duplicate certificate of Titles to the Department of Land Administration in Western Australia. The duplicate titles plus a copy of the mortgages are then filled in the security packet at ANZ. The problem here arises as a result of the duplication of the documents in order to have copies left in both offices. Another issue is to do with the entire system and how it operates. There are so many disadvantages of the current system namely: the risk of the certificates being lost, high cost of replacing lost certificates, expensive storage equipment are required for storing the certificates and the rental cost of the storage space. As much as it is a good thing it is a tedious process that needs to be elim inated as it wastes effort, time and space (Project Smart, 2011). According to this plan few options exist. The first option will be to continue having the current system which involves a lot of work and duplication of efforts. The second option that exists is to eliminate the process in totality so as to have a more efficient system that will utilize the available resources at an affordable cost to the organization. This is what the project proposes as it will have a lot of benefits. The benefits include the elimination of misfiled certificate and all the costs and penalties that are associated with them, reduction of the physical space required for the storage of these documents, reduction in paper handling/recording and transfer for both offices, security of the documents as they will be handled once and filed by the Bank staff and efficient customer service. Therefore the implementation of this initiative will go a long way in helping the Bank achieve its objectives and also hel p the

Hanover-Bates Chemical Corporation Case Study Example | Topics and Well Written Essays - 500 words

Hanover-Bates Chemical Corporation - Case Study Example District 1, 2 and 7 performances got little profits as they surpassed their gross profit quote a little (Spiro, et. al, 2008). The performance of northeast district as compared to other districts is constantly low. Other districts performed better than the set target or a little low, while northeast district performed very low. The sale of the northeast district is high, but profits are low if it is accessed in comparison with northeast central (Spiro, et. al, 2008). So, in totality, northeast district is continuously performing low as compared with other districts. Jim Sprague is quite less experienced as the new sales manager of the northeast district. However, the company’s management has trust in his skills. Hank Carver, an experienced and appreciative sales representative is interested to quit his job. The northeast district has poor performance and is unable to meet the gross profit quote. The district is not capable take benefit of potential future accounts. Their sales representative pay expenses are higher as compared to other districts. The sales representatives of northeast district have elevated own selling operating expenses. Northeast district is short of paying attention to major and medium ranged accounts (Spiro, et. al, 2008). Management’s role in improving poor performance in the northeast district is very crucial. The management should support Jim in his task by appointing supporting experienced assistant. There should be a biyearly analysis of the district in comparison with other districts. There should be incentives for outclass performers to motivate sales reps. The management should be revise its standards for the poor performing districts. Jim Sprague should install a monitoring system for the evaluation of expenses related to sales representatives (Spiro, et. al, 2008). He should conduct meetings to inform the sales reps about their elevated salaries in comparison to the sales reps of other districts and

Design of Organizational Control Mechanisms Essay Example for Free

Design of Organizational Control Mechanisms Essay Problem: When a team of individuals produce a single output the problem arises on how to contribute the reward so that every individual is equally rewarded. This article examines three different mechanisms to deal with this issue: 1.Markets Markets deals with the control problem through precise measurement and reward of individual contributions. 2.Bureaucrats Bureaucrats rely on a mixture of close evaluation with socialized acceptance of common objectives. 3.Clans Clans rely on a relatively complete socialization process which effectively eliminates goal incongruence between individuals. Introduction: Controls (by Tannenbaum)=sum of interpersonal influence relations in an organization Controls (Ezioni)= control is equivalent to power Controls (Weber)= a problem in creating and monitoring rules through a hierarchical authority system Main questions in article: 1) What are the mechanisms through which an organization can be managed so that it moves towards its objectives? 2) How can the design of these mechanisms be improved, what are the limits of each design? An example: The parts supply division Purchasing department: buys 100.000 items (p.a.) from 3.000 suppliers purchased by 22 employees on 3 management levels. †¢Purchasing officer send out request to 3 manufacturers and adds information on reliability, and the order †¢Supervisor Consults agents if they need help and reminds workers that they are not allowed to accept presents Warehousing operations: 1.400 employees (incl. 150 manager) †¢Pickers and packers (worker) †¢Supervisor (manager) Formal authority (written rules) Informal authority (personality) Three mechanisms: 1.Market mechanism purchasing function Agents and supervisory employ market mechanism: to minimize cost for the company by picking the best price on the markets. In a market prices convey all of the information necessary for efficient decision-making. Frictionless market: Prices represent exactly the value of good or service. Therefore reward can be contributed in direct proportion to contribution of employee! Agents and supervisory are subject to bureaucratic mechanisms: Their work is controlled by a set of bureaucratic surveillance controls (performance evaluation, hierarchical oder-giving) 2.Bureaucratic mechanism warehousing function Warehousing is subject to routines of monitoring and directing. This is done by close personal surveillance and direction of subordinates by superiors, based on a set of rules. Rules vs. price: Rules are arbitrary (beliebige) standards without comparison, based on assigned values of (successful) actions. Prices imply that a comparison has already taken place. Prices are far more efficient means of controlling transactions than are rules. However, the conditions necessary for frictionless prices can rarely be met, and in such conditions the bureaucratic form, despite its inadequacies, is preferred. 3.Informal social / clan mechanism Supervisors can rely on bureaucratic mechanisms but this requires surveillance which is associated with costs. But when the supervisor knows that his workers achieve the right objectives, he can eliminate many of the costly forms of audition and surveillance. Social and informational prerequisites of control The three models can be arranged along two dimensions: 1.Informational requirements =prerequisite to successful operation 2.Social underpinnings = Set of agreements between people, as a bare minimum, is basis for control Type of controlSocial requirementsInformational requirements MarketsNorm of Reciprocity (Wechselwirkung) Prices BureaucracyNorm of Reciprocity Legitimate authorityRules ClanNorm of Reciprocity Legitimate authority Shared values, beliefsTraditions The informational prerequisite of control: While a Clan is the most demanding and the Market the least demanding with respect to social underpinnings, the opposite is true when it comes to information. Within large organizations departments tend to develop own jargon in which complex information is easily transported. Each system carries information on how to behave: †¢Explicit system: accounting system easily accessible by newcomer (system is created) †¢Implicit system: is far less complete in its ability to convey information. e.g. US Senate need years to understand flow of information (systems grow up) Companies attempting to control the organization through a price (=market) mechanism use transfer prices to represent prices of internal performances. The advantage should be obtained by using the best prices within the firm. Organizations can also create an explicit set of rules (behavior as well as production and output) that will cover every situation and therefore cut the information problem down by using rules that will cover 90% of all events and depending upon hierarchical authority to settle the remaining 10%. Again legitimate authority is critical to bureaucracy. In a Clan the information is contained in the rituals, stories and ceremonies. So to say the information system does not require a information system, its just there. For example Chinese-American Hui: conducts business as venture capital lender but they also enter risky businesses and even the repayments are left open. Entry is only granted by birthright, a practice that guarantees that every member is part in the same social network and therefore behave to the same rules and principles. While the Market and Clan are both specialized approaches it is the Bureaucratic which is the system that is most flexible. Of course, under certain circumstance both the Market and Clan approach will deliver better results but the Bureaucratic can withstand high rates of turnover, a high degree of heterogeneity and it does not have very demanding informational needs. Designing Control Mechanisms: Costs and Benefits Two ways of effective people control: 1. Find people that fit needs exactely 2. find people that dont fit exactly but use a managerial system to instruct, monitor and evaluate them Best approach depends on costs. Ad 1. is associated with costs and search and acquisitions but their skills will help to reduce costs in the long-run. Ad 2. includes trainings costs and a the costs for the supervisory system but reduces high turnover. Search and select ‘clan-type’ people: Cost of Search and Acquisition: High Wages Benefit: Perform tasks without instruction, work hard Instruct people into the ‘clan’ system: Cost of training: instruct, monitor, and evaluate unskilled workers (who are likely to be indifferent to learn organization skills and values). High rates of turnover. Costs of monitoring: developing rules, supervising. Benefit: heterogeneous system of people that can be controlled. Explicit rules (codified knowledge) offset turnover costs. Loose coupling and The Clan as a Form of Control New view with impact on designing control mechanisms. The ability to measure either output or behavior which is relevant to the desired performance is critical to the rational application of market or bureaucratic forms of control. Knowledge of transformation process: Tin Can plant: If we understand the technology (e.g. production process and what it takes for a successful production) perfectly, we can achieve effective control by setting rules that lead to behavior and processes that lead to our desired transformation steps. Thus, we can create an effective bureaucratic control mechanism. Womens boutique: On the other hand, if we dont understand what is needed (e.g. control system for womens boutique) to be a successful buyer or merchandiser, we cant create rules. But we can measure output (turnover per buyer, salex volumes,). So we can use the output control mechanism to monitor various indicators and set actions accordingly. Apollo Program: Each step of the transformation (assembling) is crystal clear and we have a output measure (it comes back or not). Thus we have the choice and the lower cost alternative will be preferred: clearly as the cost of failure would be prohibitive (untragbar) and more elaborate behavior control system will be installed. Reseach Lab: We have the ability to define the rules of behavior and we can measure the output which will be some 10 years in the future. Certainly a strong output control system will be used but effectively this cannot guarantee success so neither behavior nor output measurement will be sufficient, leaving us with no rational form of control. Therefore such organizations rely on ritualized, ceremonial forms of controls. This approach only works with the recruitment of a selected few individuals, with the same schooling and professionalization process. Another organizations using this form: Hospitals, Investement banks, Whereas output and behavior control can be implemented through a market or bureaucracy, ceremonial forms of control can be implemented through a clan. Closing observations Depending on the organization and its requirements it has to be choosen which control systems works best. E.g.: manufacturing: behavior and output control vs. service org.: cultural or clan controls. Nevertheless every control system is directed at achieving cooperation by: †¢Market mechanism: each persons contribution is evaluated; combined with a personal loss of reward †¢Clan mechanism: attain cooperation by selecting and sozialising individuals such that their objectives overlap with the organizations objectives †¢Bureaucratic mechanism: does a little of each, partly evaluates performance and partly engenders feelings of commitment to the idea of legitimate authority in hierarchies Two main questions: 1. Clarity with which the performance can be assessed 2. Degree of goal incongruence (either trust each other or control each other)

Technological Considerations in Interface Design

Technological Considerations in Interface Design Technological Considerations in Interface Design Physical characteristics of the device and device internal software affects the screen interface design. Graphics compatibility for Screen design must be ensured with the following system components: System power. Screen size. Screen resolution. Display colors. Other display features. Development and implementation tools being used. System platform being used. Platform style guide being used. Information Retrieval (IR): it concerns with the study of finding required data. i.e., IR helps users to notice data that matches their data desires. Technically, IR studies the organization, acquisition, distribution, storage, and retrieval of data. Information retrieval models An IR model directs how a document and a query are characterized and how the significance of a document to a user query is defined. Following are the main models in IR Boolean model Each document or query in Boolean model,is treated as a â€Å"bag† of words or terms. Mathematically for a given collection of documents D, let V = {t1, t2, ,t|V|} be the set of distinctive words/terms in the collection. V is called the vocabulary. A weight wij> 0 is associated with each term tiof a document dj∈D. For a term that does not appear in document dj, wij= 0. dj= (w1j, w2j, , w|V|j), Query terms are combined together logically using the Boolean operators such as AND, OR and NOT. Example : ((data AND warehousing) AND (NOT text)) Vector space model (VSM) In VSM too, Documents are treated as a â€Å"bag† of words or terms. Each document is represented as a vector. However, the term weights are no longer 0 or 1. Each term weight is computed based on some variations of called Term Frequency TF or TF-IDF scheme. Term Frequency (TF) Scheme: The weight of a term tiin document djis the number of times that tiappears in dj, denoted by fij. Normalization may also be applied. ,, Here, tf: still term frequency idf: inverse document frequency. n: total number of docs dfi: the number of docs that ti appears. 1.5.5 Popular HCI Tools HCI Browser This Browser (HCIB) is designed and implemented by the research team of North Carolina University.

Right now, existing software tools support pen and ink input to certain extent only. There is a need for intelligent software that can sketch, recognize and convert the natural sketches automatically. Following are such tools: Inkkit It is a toolkit used to sketch diagrams. It can be applied over a range of domains. This software is able to run on a Tablet PC. InkKit consists of the following: User Interface The user interface is supported by two main views: sketch pages This view supports easy drawing process. portfolios. Here this point displays a set of sketches. These sketches can be linked to enable relationships. Recognition Engine The power of InkKitis its recognition engine To recognize a specific diagram, it creates a diagram domain and provides examples. The sketches on this user interface design will normally be converted into both HTML and Java. It is a research tool designed for non-commercial purpose. Freeform Freeform tools provide a pen based interface. This tool is mainly used to design controls in the forms by hand sketching. Requirements :Visual Basic Features: Designs of user interfaces are quicker and easier than creating them with a form builder. SketchNode Sketchnode is a tool used to draw graphs with edges and nodes easily. This tool runs on Tablet PC. Design in this tool can be either done by pen or using drag and drop interaction. Optimization algorithms are used for transforming of not clear graph into a clearer one. Features: supports both low and high fidelity graph rendering. Easy design process No convolution of images due to optimization. Intelligent Mind Map Humans effectively and effortlessly split between drawing and writing ink. This split is difficult to achieve in digital systems. This tool supports for the informal document on the tablet PC by recognition and ink reflow techniques. TATool This tool is designed to generate task representations in hierarchical manner. This research was carried out in the Patras University. The original task of this TATool is to analysis the task in interactive system design. It is recognized as a common tool to design hierarchical structures and Visualized objects This tool TATool generates output in XML form and an RTF report. This software runs only on Windows OS. It maps user-system interaction’s recorded events to the process model. COGTool It is one of the HCI tools used to predict total execution time for a skilled user for performing a particular sequence of actions on a system. The predictions made by CogTool are based on, a psychological theory of human cognitive and motor capabilities, called the Keystroke-Level Model (KLM). Following are the features: automates the application of KLM to specific problems, providing an alternative to time-consuming and expensive user testing. predicts what KLM can predict, that is, execution time for a skilled user of a system. Drawbacks It cannot predict learning time, problem-solving paths, or user satisfaction with a system. CMTool CMTool aims to achieve the task modelling process. Any major task can be splitted into many sub tasks by divide and conquer strategy and organising the task in hierarchical structure. This tool uses this hierarchical way along with logical operators such as AND , OR , NOT to solve the sub task. Following are its features: supports graphical and character notations for task representation. supports temporal analysis for each task supports relational database, grouping the various systems analyzed, with additional identification information. supports quantitative analysis tools for the task metrics provides various representations of data in the form of tree view , report view , structured view. automates synthesis of task structures already stored 1.6 Architecture of HCI systems Architecture of a HCI system should describe the working procedure of cooperation between inputs and outputs. There are two standard HCI architectures as follows: Unimodal systems Multimodal systems 1.6.1 Unimodal Architecture Modality means an independent single channel. Unimodal systems are designed based on single modality. They are further classified based on the nature as follows: Visual Audio Sensor 1.6.1.1 Visual HCI: Its application areas are facial expression analysis, Body movement tracking, gesture recognition and Gaze detection. Table 1.7 – Visual HCI Research areas 1.6.1.2 Audio HCI This uses various audio signals to acquire information. They are helpful, unique and trustable. It’s application areas are speaker recognition, musical integration, auditory emotion analysis and Human made noise or sign detections. 1.6.1.3 Sensor HCI It uses atleast one sensor between user and computer to enable interaction. Examples of sensors are not limited to pen based interaction, joysticks, mouse-keyboard, haptic sensors, taste or smell sensors, pressure sensors and motion tracking sensors. 1.6.2 Multimodal Architecture It combines multiple modalities. Here modalities refer to communication channels. The channels are sensors for sight ,taste , hear ,smell and touch. Gesture ,speech and gaze are common forms of input models. The examples of multimodal applications are not limited to smart video conferencing, driver monitoring, intelligent games, helping disable people and smart homes. 1.7 Advances in HCI Ubiquitous Computing and Ambient Intelligence: It is also known as third way of computing that is interaction among many computers and one person. The evolution is as follows: First way of computing main frame era many people one computer. Second way of computing PC era one person many computers. 1.8 Overview The remaining part of this book includes both theoretical material and practical approaches to designing user interfaces. The topics include: Usability engineering principles Experimental and prototype cognitive architectures Design of effective spoken dialogue systems Role of recommender [e1]systems in web technologies Advanced visualization techniques based on ontologies Intelligent and adaptive HCI Ubiquitous computing and Ambient Intelligence. 1.9 HCI Sample Exercises Application of Weber’s Law in the design of Human Interfaces Weber’s Law It states that the size of the observable various is a constant proportion (K times) of the actual stimulus value. Stimulus intensity must be changed with a minimum amount to create a observable difference in sensory experience. Weber’s Law to user interfaces Information in a computer can be displayed in various formats such as text, pictures, drawings, maps, graphs, videos etc. This information may be from small to large in size with respect to the following: Brightness loudness line length visual weight of fonts in typography color matching Weber’s law helps to analyze and design the above effectively.
