System of Inquiry - Research Paper Example Lateness is a hallmark of laziness. It shows that the individual being late is not taking enough time out in his or her day to plan the day out so that they will budget enough time to do everything that needs to get done. People who are disorganized generally have such difficulty keeping up with all the things going on around them, that they cannot focus on what is happening now. Thus, people who are disorganized are generally (but not always) late. Once people know someone is disorganized so much that they always arrive places late, they usually don't give these people the benefit of the doubt. They probably figure that this person is so discombobulated that they have no clue how to run their own lives, and, it follows that these people are probably not trusted by many people to follow through. Being late is generally a characteristic that should be looked upon with shame. Therefore, if one is always prompt, one can be proud, hold one's head up high, and know that responsibilities were taken seriously enough to have the respect for others to come to work or school on time or early. In other words, what we do matters. ... Once people know someone is disorganized so much that they always arrive places late, they usually don't give these people the benefit of the doubt.

It is a hallmark of an upstanding individual in the community to always be polite. "Politeness means speaking and acting in a civil way and using good manners" ("Character Attributes," 2010, p. 1). Generally, "[p]oliteness is best expressed as the practical application of good manners" ("Polite," 2010, p. 1). One may ask, "Why be polite" Polite people are more likely to get ahead in life in many ways. People who are polite have doors opened for them, and open doors for other people (literally and figuratively). Generally, people who are mean and rude are not going to get promoted at work. Nor will rude and mean people be given the benefit of the doubt when something goes wrong in their lives. People who are rude and mean are not pleasant to be around. People who are polite are much more pleasant and inviting people, and therefore people don't mind hanging around people who are polite. Politeness will bring a person success in life. No matter who one is, politeness can open doors for people. People who are nice may be more favored to get a raise. Polite people may also be

Importance of Cell Cultures

Importance of Cell Cultures Introduction Cell culture is an extremely widely used process by which cells are removed from their natural environment and grown artificially under controlled and monitored conditions. It occurs in vitro, or in glass, more specifically in multicellular eukaryotic cells. The cells may be removed from their habitat directly and disaggregated with enzymes or mechanically before harvesting, or they may be a derivative of a cell line that has been created previously. It was adapted from a practice used in the early 1900s and since then it has expanded and advanced research and scientific knowledge enormously. The conditions required for each culture vary, however the artificial environments conditions are consistent. It must consist of a suitable vessel which contains a medium that provides vital nutrients such as amino acids, vitamins, carbohydrates and minerals. Growth factors and hormones are also needed, as well as oxygen and carbon dioxide. It must monitor and regulate physico-chemical environme nt which includes pH and osmotic pressure, as well as temperature. Temperature is kept at 37Â °C, CO2 levels at 5% and humidity at 95%. Cell cultures are an extremely important tool for healthcare scientists. They provide a model system for physiology and biochemistry of selected cells to be studied. By examining their physiology their aging pathway can be studied and their biochemistry allows processes such as metabolic rate to be observed. The cells interaction with drugs could also be observed which proves a useful tool for drug screening programs, clinical trials and pharmaceutical companies. Whatever the purpose for using cell cultures, it is an extremely consistent and reliable process that has good reproducibility of results that can be obtained using a batch of clonal cells. Primary cell cultures are cultures that grow and maintain cells dissociated from their parental tissue via mechanical or enzymatic methods. They can be either adherent or suspension cells. Adherent cells are also known as anchorage dependent cells because they require attachment for growth. These cells are usually derived from organs such as the kidney where they are immobile and implanted into connective tissue. Suspension cells are the opposite and dont require attachment to the culture vessel for growth. These types of cells are anchorage independent cells. They are cells that derive from the blood, where they arent attached to anything but are still suspended e.g. in plasma like lymphocytes. A secondary culture is a primary culture that has been sub-cultured. The sub-culture (passage) occurs when the cells are transferred from a culture vessel to another. This provides fresh nutrients and space for continued growth, because a primary culture has a finite life span. Common primary and secondary lines can be found in Table 1. After the first sub-culture, the culture becomes known as the cell line. Cells only undergo a finite number of replication cycles before cell death. This means that some cell lines will be finite cell lines. However, some cells undergo transformation. This can occur spontaneously but can also be virally induced in vitro. Undergoing transformation gives the cell the ability to divide infinitely, such as HeLa cells. The HeLa line is the oldest and most commonly used continuous cell line. Cervical cancer cells biopsied from Henrietta Lacks in 1951 show that they are remarkably durable and prolific. In 2012, Turner published a paper documenting its importance in the development of the polio vaccine.

It is used in research against SV40, a cancer causing virus that was hidden in the polio vaccine (Vacante et al., 1989). The Hep G2 cell line is another continuous cell line of hepatocellular carcinoma. It plays a vital part in the research of human liver diseases by being a model for intracellular trafficking (Mersch-Sundermann et al., 2004). Jurkat cells, another continuous line, are a line of lymphocyte cells used to study leukaemia, T-cell signalling and HIV (Wang et al., 2012). This review will explore the use of cell lines in the laboratory and their applications. SH-SY5Y will be a particular focus, and will explore the application and importance of the cell line as one of the only lines used to study neuronal function and differentiation. SH-SY5Y cell line SH-SY5Y cells are a derivative cell line used majorly in scientific research. SH-SY5Y originally was cloned from a biopsy of bone marrow derived line called SK-N-SH, and then named as SH-SY. The biopsy was from a 4-year old female with neuroblastoma. This was subcloned again to make SH-SY5 and subcloned once more to form SH-SY5Y. Because this cell line has been derived from a primary source, it is a secondary culture. There is new, fresh growth medium in which the cells are suspended not attached, making them anchorage-independent cells in the cell line. They have been widely used since the 1980s, due to their ability to express dopaminergic markers and neuronal function such as neurodegenerative processes. Because of these characteristics, they play a major role in the research of Parkinsons disease. As mentioned before, the cells are subcloned. This process of sub-culturing is also known as cell passaging. Cell passaging is where a new microbiological culture is created by transferring a sample, or all, of a cell culture to a different growth medium. This process prolongs the life of the organism, renews depleted nutrient levels and also increases the concentration of cells in the culture. Cells cannot be held in their primary culture indefinitely because continual cell activity means there will be a gradual rise in toxic metabolites. For SH-SY5Y cells, there is a recommended limit of cell passaging. Passage numbers can affect cell physiology and morphology, protein expression and transfection efficiency, so the limit has been set to 20 to prevent unreliable and irreproducible results being collected. Use of SH-SY5Y cell line in research As conferred, SH-SY5Y is one of the only cell lines that can be used as a model system for neuronal function investigation. It is particularly good for investigating the effective of oxidative stress on neuronal cell lysis. Reactive oxygen species (ROS) at specific concentration are essential for standard cell function however over exposure to ROS is harmful to cells. There are 2 globins whose functions are still unclear. Neuroglobins (NGBs) and cytoglobins (CYGB) role has been suggested to involve detoxifying the effects of over exposure. Excessive ROS has been known to cause cell lysis after ischaemic strokes. By investigating the correct levels and limit levels of ROS it can have an enormous clinical impact on stroke recovery and treatment. Forde et al. investigates the effect of NGB and CYGB on the detoxification of ROS. The influence of cell lysis of surplus ROS is the primary focus, more explicitly hydrogen peroxide. SH-SY5Y cells were cultured at a ratio of 1:1 of Dulbeccos minimum essential medium (DMEM) and Hams F-12 nutrient medium along with 10% foetal bovine serum at 5% CO2 atmosphere. The culture was maintained at 37Â °C in a humidified 95% atmosphere. L-glutamine provided an energy source and sodium bicarbonate acts as a pH buffer. Growth factors and non-essential amino acids (NEAA) are also present and standard factors. In the culture, penicillin and streptomycin are the selected antibiotics used. The pathogen cell membranes are broken down to prevent infection. In cell lines cross contamination can be rife, so using antibiotics prevents this and induced recombinant protein expression. Apart from preventing the obvious infection risk, if there is contamination there will be unreliable and inaccurate results. However, antibiotic resistance means that there may always be a level of low contamination. The prolonged use means antibiotics are only used where absolutely necessary so that it p revents these problems, such as in initial cell lines to prevent contaminated cells being carried on in sub cultures and protecting stock solutions. Methods and Materials After SH-SY5Y had been cultured, they then were transfected. NGB and CYGB plasmids were transfected with SH-SY5Y by nucleofectin. Nucelofectin is a transfection method that requires the use of electrode force to administer specific voltage. Reagents and electrodes produce the conditions required for transfection, which increases the permeability of the target cell. This allows the genetic material present in the culture to transfect into the globin plasmids. This is a reliable mechanism and produces good rates of success. After transfection, the globins were fused with the GFP gene by PCR-amplification. The NGB to CYGB region was amplified and digested with restriction enzymes. Ligation was then performed directly after in to PEGFP-N1 vectors. The culture cells were briefly re-suspended in nucelofactor solution and nueclofected with 2ÃŽ ¼g of plasmid DNA, producing a final result of NgbN1-pEGFP and CygbN1-pEGFP fusion proteins. These produce a yield of 40% eFP positive cells. The PCR identified the expression To examine the success of the transformation, PCR determined the expression of the globins. PCR measures the expression by recording the amount of mRNA present before and after amplification. For reactions involving GFP, fluorophene is added to act as a marker and signal upon excitation. Upon examination, over a 12 hour period there was upregulation 12 hours after transfection, meaning the globins were transfected successfully. This examination isnt thorough enough to provide evidence of success. A western blot was performed to ensure thorough examination. Protein expression can be detected by electrophoresing the proteins through a 10% polyacrimide gel. The proteins were transferred on to a western blot by being electroblotted to an Immobilon P membrane. After staining with primary polyclonal antibodies they were incubated with a secondary antibody, and probed for antibodies upon completion with Supersignal West Pico Chemiliminescent substrate. Figure 1 displays the result of the western blot.

Truth in Keats Ode on a Grecian Urn and Cummings since feeling is fir

Truth in Keats' Ode on a Grecian Urn and Cummings' since feeling is first Truth remains a mysterious essential: sought out, created, and destroyed in countless metaphysical arguments through time. Whether argued as being absolute or relative, universal or personal, no thought is perceived or conceived without an assessment of its truth. In John Keats' "Ode on a Grecian Urn" and E.E. Cummings' "since feeling is first" the concern is not specifically the truth of a thought, but rather, the general nature of truth; the foundation which gives truth is trueness . Both poets replace investigation with decision, and that which would be argumentation in the hands of philosophers becomes example and sentiment in their poems. Each poet's examples create a resonance within the reader, engineered to engender belief or provoke thought. Employing images of unconsummated actions on an ancient urn carved with scenes from life, Keats suggests that "Beauty is truth, truth beauty"; Cummings, on the other hand, offers emotion as the foundation of truth, and supports living li fe fully through diction, theme-suggestive syntax, and images of accomplished action. Cummings' "since feeling is first" compares the beauty of emotion and the inadequacy of mental analysis. In line three, attention to "syntax," synonymous with literary construction and order, ruins emotional spontaneity, symbolized by a kiss. "Wholly to be a fool while Spring is in the world" ignores social convention in seeking pleasure while "fool" and "Spring" complement each other and suggest the blossoming of love. Line six, "my blood approves," focuses on the physical root of life and evades the hackneyed connotative baggage that arrives with the word "heart." Cummings then swear... ...ing reality and easily equated to the story told by the "Sylvan historian." Thus, the urn as historian provides the truth spoken of in the final line. Literally, the truth of the urn (its representation of life) is its beauty. The derived equivalence of truth and beauty allows the concluding statement: "Beauty is truth, truth beauty." Through similar rhetorical features, "since feeling is first" celebrates love and extols the virtue of intuitive, spontaneous emotion. Cummings' use of sensual imagery discounts methodical analysis and offers emotion as truth. Both poems arrive at seperate conclusions and reflect the diversity of perspectives regarding the nature of truth. Works Cited Brooks, Cleanth. The Well Wrought Urn.

An Unfortunate Influence and Its Tragic Outcome Essay

In every person’s life there are many factors that occur throughout, both negative and positive influences that alter the path one chooses. In the world renowned play Romeo and Juliet by William Shakespeare, the tragic outcome is brought about by the lovers’ trusted friend, Friar Lawrence. To begin with, Friar Lawrence is to blame for setting the events into motion by marrying Romeo and Juliet. Then, Friar Lawrence is responsible for Juliet receiving the potion that causes everyone to believe that she is truly dead. Finally, Friar Lawrence could have prevented the two deaths by simply making sure that Romeo gets the message as he assured Juliet he would. So ultimately, Friar Lawrence is responsible for the star crossed lovers’ demise, because they wrongly trust the Friar and his influence causes Romeo and Juliet to make all the wrong decisions thus bringing about their downfall. Before any tragic incidents actually occur in the play, Friar Lawrence sets the entire series of unfortunate events into motion by secretly marrying Romeo and Juliet. When Romeo first arrives at the Friar’s cell to declare the love he now feels for Juliet, Friar Lawrence immediately notes how foolish Romeo is being, for just the day before he had been so in love with Rosaline and devastated that she did not return that love. Friar Lawrence says, â€Å"Is Rosaline, that thou didst love so dear, / So soon forsaken? †¦ And art thou chang’d? Pronounce this sentence then: / Women may fall, when there’s no strength in men† (2.3.66-80). Friar Lawrence right away states that it is ridiculous that Rosaline, with whom Romeo was borderline obsessed, has already been replaced with a girl in a matter of days. However, Friar Lawrence then blatantly turns around and contradicts what he says about Romeo behaving foolishly, by agreeing to marry Romeo and Juliet. Friar Lawrence agrees saying, â€Å"In one respect I’ll thy assistant be. / For this alliance may so happy prove, / To turn your households’ rancour to pure love† (2.3.90-92). Friar Lawrence agrees to secretly wed Romeo and Juliet despite what he says earlier about the proposal. Friar Lawrence could have easily prevented the tragedy if he had just gone with his first instincts. However, he sees the opportunity to stop the feuding between the Capulets and Montagues and jumps at it to become the big hero, therefore making him selfish and irresponsible as well as a bad influence. Friar Lawrence sets Romeo and Juliet’s deaths into motion the second he agrees to Romeo’s plan, and in doing so Friar Lawrence is to blame for the untimely deaths of Romeo and Juliet. Not only does Friar Lawrence trigger Romeo and Juliet’s demise, he also continues the chain of tragic decisions by giving Juliet the sleeping potion that leads Romeo to kill himself. When Juliet runs to Friar Lawrence’s cell in utter desperation, he should have taken the time to advise her against such drastic measures and help her make the responsible choice where Romeo is concerned. Instead, Friar Lawrence hands her a sleeping potion that will create the illusion of death for the drinker: Take thou this vial, being then in bed, And this distilling liquor drink thou off,†¦ Now when the bridegroom in the morning comes To rouse thee from thy bed, there art thou dead (4.1.93-108). Friar Lawrence assures Juliet that everything will be okay and the potion will work in tricking her parents and Paris into believing she is truly dead. He places the vial in her hand and does not do anything to prevent Juliet from making this fatal decision. Friar Lawrence just continues to reassure Juliet by saying, â€Å"And hither shall he come, and he and I /Will watch thy waking, and that very night / Shall Romeo bear thee hence to Mantua† (4.1.115-117). Friar Lawrence promises Juliet that word of their plans will reach Romeo and when she wakes from her sleep-like trance, Romeo will be there to run away with her to Mantua. Friar Lawrence just keeps on telling Juliet that it will all work out fine, without pausing to think about all the possible dangers and side effects that may come from drinking the vial. Again, Friar Lawrence is being irresponsible and rash, holding two teen’s lives in his hands. Friar Lawrence gets carried away and swept up in Romeo and Julietâ €™s twisted fantasy and helps Juliet make a foolish decision that helps bring about the lover’s demise. Therefore, Friar Lawrence is to blame for the deaths of Romeo and Juliet. Even after all the irresponsible choices Friar Lawrence makes throughout the play, he still could prevent the tragic outcome by simply making sure that Romeo receives news of the Friar’s and Juliet’s plan. But alas, Friar Lawrence does not follow through and assure that the messenger arrives soundly in Mantua. One of the main reasons Juliet is able to take the potion without many concerns or worries is because she thinks that when she wakes in the monument, Romeo will be there to whisk her away with him. When Juliet is confused and in a highly vulnerable state, Friar Lawrence hands her the vial saying, â€Å"In the mean time, against thou shalt awake, / Shall Romeo by my letters know our drift† (4.1.113-114). Friar Lawrence tells Juliet that while they wait for her to awake, Romeo will receive a letter informing him of their plans. However, the messenger Friar Lawrence sends, Friar John, never makes it to Romeo and by the time Friar Lawrence actually finds out, h e knows that a great mistake has taken place and danger is going to ensue: Unhappy fortune! By my brotherhood, The letter was not nice but full of charge, Of dear import, and the neglecting it May do much danger (5.3.17-20). Friar Lawrence finally realizes the danger that Romeo and Juliet face. He understands that something terrible may happen because the information never reaches Romeo. However, it is too late by the time he arrives at the monument and Romeo, who received false information from Balthasar, is already lying dead beside his stirring wife. When Juliet does officially wake, she is devastated to see her loving Romeo dead, and desperate to be with him again. Instead of calming Juliet down and bringing her to safety, Friar Lawrence selfishly runs away when he hears the Watch coming. He leaves a desperate teenage girl there to stab herself and be with her Romeo for eternity. The incident with the letter leads Romeo to commit suicide and subsequently have Juliet kill herself to be with Romeo. The Friar does not make sure that the letter reaches Romeo and two premature deaths occur instead, conclusively leaving Friar Lawrence to blame. Friar Lawrence is a trusted friend and confident of Romeo and Juliet, yet he negatively influences the two lovers and guides them down a wrong path ending with a double suicide. Friar Lawrence triggers the start of the downfall by irrationally agreeing to wed Romeo and Juliet. Friar Lawrence then gives Juliet bad counsel and advises her to make a catastrophic decision the second he places the vial of sleeping potion into her palm. Friar Lawrence still could evade the entire tragedy, but inadvertently breaks his promise to Juliet and never assures that the letter makes it to Romeo in Mantua. The star crossed lovers’ downfall is caused by the irresponsible and selfish Friar Lawrence because if Romeo and Juliet had not gone to Friar Lawrence for counsel and advice, they would not have been encouraged to follow through with their foolish fantasy and lived. The love between Romeo and Juliet was genuine, and the pain they felt when they heard of the other’s death was real. Kn owing that one person, especially someone as close to them as Friar Lawrence, is to blame for the tragic ending is horrible and tragic in itself, because if Friar Lawrence had just thought through his actions Romeo and Juliet might have lived a long and happy life together.

Drawbacks of the Common Law System

Explain the drawbacks of the common law system in England and Wales. ‘Common law’ originated in England in the 11th century. Today in the United States of America, some common law principles from the original English Law are being applied.Alongside it is the branching body of Common Law which is in the process of being set as a part of stare decisis which itself is an abbreviation of the Latin phrase ‘stare decisis et non quieta movere’ which translates as ‘to stand by decisions and not to disturb settled matters’, whereby the judicial systems decisions and interpretation of statutory law provisions by judges, are becoming a part of the common law. Judges too do look to these decisions as a guideline, reference or as a necessary precedent to follow, whilst making their own decisions.Although advantages of the system have been significant in England and Wales, drawbacks of the system gradually came on par. As these decisions are based on past cas es, predictability of the outcome increased and people are more exposed to what should be expected, however so, with the element of predictability, absurdity on deciding cases may occur. In referring to a decided case, if there appears to be no change and the decision is followed again by a judge, a bad decision will eventually be perpetuated.And considering common law systems have been following precedents as a base, changes takes a long time to happen. In the meantime, a bad decision from a past case continues to be upheld. It became a major criticism of common law systems that it can be hard to locate the relevant principles due to the available volume of material. Common law which was based on the principle of binding precedent meant that judges must follow precedent even if they disagree with it.Judges too were not able to distinguish essentially similar cases although they were on grounds decision made would be inappropriate. Lord Denning too criticised the doctrine to stand b y what has been decided by saying, â€Å"if lawyers hold to their precedents too closely, forgetful of the fundamental principles of truth and justice which they should serve, they may find the whole edifice comes tumbling down about them. Just as the scientist seeks for truth, so the lawyer should seek for justice.Just as the scientist takes his instances and from them builds up his general propositions, so the lawyer should take his precedents and from them build up his general principles. Just as the propositions of the scientist fail to be modified when shown not to fit all instances, or even discarded when shown in error, so the principles of the lawyer should be modified when found to be unsuited to the times or discarded when found to work injustice. , which in other words meant accepting the decisions of old law leads to unfairness and injustice. Furthermore, when precedent appears absent the common law legal system will be bound to face difficulties in making judgements. D ifficulties will arise and flood various parties which include judges and those with intention to claim justice will be at lost with the unavailability of a decided precedent to refer to. This has been said on certain occasion to lead to a high degree of unpredictability based on illogical distinctions.

Modernization and Dependency essays

Modernization and Dependency essays Dependency is a process associated with the economies of many Third World countries that is formatted in terms of external factors. Dependency exists when a country relies on a single (or a limited few) exports that are sold to more industrialized countries, manufactured and then resold to the country of origin for a higher price. This means that a country's income from exports is continually insufficient to meet the cost of The nature of dependency theory categorizes countries into one of two types: dominant and dependent. Many formally colonized countries (such as India) were organized along this type of economic structure. The primary state was automatically the imperialist overseer and the dependent state was the colony. Single export economies were also common within the colonial network (consider coffee from Brazil or sugar from the Caribbean). Dependent states tend toward a low per capita GNP as direct result of their dependency. "The dependent states supply cheap minerals, agricultural commodities, and cheap labor, and also serve as the repositories of surplus capital, obsolescent technologies, and manufactured goods. These functions orient the economies of the dependent states toward the outside: money, goods, and services do flow into dependent states, but the allocation of these resources are determined by the economic interests of the dominant states, and not by the economic interests of the dependent Economic dependency is a result of direct intervention and manipulation of the economic structure in poorer countries. Industrialization is limited as a result of outside control and domination. These are countries that are exploited for the purpose of providing specific export products and, or, cheap labor to the detriment of the native population and the benefit of the dominant state. Politically, ...

Rajasaurus, the Deadly Indian Dinosaur

Rajasaurus, the Deadly Indian Dinosaur Also known as theropods, meat-eating dinosaurs- including raptors, tyrannosaurs, carnosaurs, and too many other -saurs to list here- had a wide distribution during the later Mesozoic Era, from about 100 to 65 million years ago. An otherwise unremarkable predator, except for its small head crest, Rajasaurus lived in what is now modern-day India, not a very fruitful location for fossil discoveries. It has taken over 20 years to reconstruct this dinosaur from its scattered remains, discovered in Gujarat in the early 1980s. (Dinosaur fossils are relatively rare in India, which helps explain why the regal word Raja, meaning prince, was bestowed on this carnivore. Oddly enough, the most common Indian fossils are ancestral whales dating from the Eocene epoch, millions of years after the dinosaurs went extinct!) Why did Rajasaurus possess a head crest, a rare feature in carnivores that weighed in the one-ton-and-over range? The most likely explanation is that this was a sexually selected characteristic, since colorfully crested Rajasaurus males (or females) were more attractive to the opposite sex during mating season- thus helping to propagate this trait through succeeding generations. Its also worth noting that Carnotaurus, a close contemporary of Rajasaurus from South America, is the only identified meat-eating dinosaur with horns; perhaps there was something in the evolutionary air back then that selected for this characteristic. It may also be the case that the crest of Rajasaurus flushed pink (or some other color) as a means of signaling other pack members. Now that weve established that Rajasaurus was a meat-eater, what, exactly, did this dinosaur eat? Given the paucity of Indian dinosaur fossils, we can only speculate, but a good candidate would be titanosaurs- the gigantic, four-legged, small-brained dinosaurs that had a global distribution during the later Mesozoic Era. Clearly, a dinosaur the size of Rajasaurus couldnt hope to take down a full-grown titanosaur all by itself, but its possible that this theropod hunted in packs, or that it picked off newly hatched, elderly, or injured individuals. Like other dinosaurs of its kind, Rajasaurus probably preyed opportunistically on smaller ornithopods and even on its fellow theropods; for all we know, it may even have been an occasional cannibal. Rajasaurus has been classified as a type of large theropod known as an abelisaur, and was thus closely related to the eponymous member of this genus, the South American Abelisaurus. It was also close kin to the  comically short-armed Carnotaurus mentioned above and the supposed cannibal dinosaur Majungasaurus from Madagascar. The family resemblance can be explained by the fact that India and South America (as well as Africa and Madagascar) were joined together in the giant continent Gondwana during the early Cretaceous period, when the last common ancestor of these dinosaurs lived. Name: Rajasaurus (Hindi/Greek for prince lizard); pronounced RAH-jah-SORE-us Habitat: Woodlands of India Historical Period: Late Cretaceous (70-65 million years ago) Size and Weight: About 30 feet long and one ton Diet: Meat Distinguishing Characteristics: Moderate size; bipedal posture; distinctive crest on head

IMO Ballast Water Exchange and Performance Standards

IMO Ballast Water Exchange and Performance Standards In order to reduce damage from aquatic invasive species the International Maritime Organization (IMO) developed the â€Å"International Convention for the Control and Management of Ships Ballast Water and Sediments†. The BWM convention began with the IMO’s Marine Environment Protection Committee (MEPC) in 1991. Since then there have been many revisions. Some of these revisions were driven by advancing technology to remove unwanted organisms at flow rates that would not severely impact operations. Treatment of ballast water with the latest technology can meet standards at a rate of 2500 cubic meters (660,430 US Gallons) per hour. A large vessel may still take several hours per exchange to flush her ballast tanks at this rate. Flow rates and energy consumption must be acceptable to operators while producing no harmful effects on the environment. Ballast Water Standards There are two types of ballast water standards in the convention. Their differences are significant and they should not be directly compared. The first, Ballast Water Exchange, is based on specified distances and depths where a vessel may discharge. Ballast Water Performance is a standard based on the number of viable organisms allowed per unit of treated water. Some areas are instituting standards which exceed the IMO guidelines. Both California and the Great Lakes region of the United States have adopted stringent local guidelines. The US is one of many major shipping nations that have not signed the convention. Thirty nations who have a combined merchant gross tonnage of thirty-five percent of the global tonnage are needed to ratify the convention. Ballast Water Exchange The standard for ballast water exchange is fairly simple. A vessel must discharge foreign ballasts at a specified distance from shore and at a specified depth using a submerged discharge device. Regulation B-4 and D-1 of the BWM convention gives us the specifics. Exchange may take place 200 Nautical Miles (NM) from shore at a depth of 200 meters. If that is not possible for safety or other reasons then a vessel may use the next procedure.If neither of these scenarios is possible then a vessel may exchange â€Å"in an area designated by the port state†. While undertaking ballast water exchange a port state must not cause deviation or delay of a ship.Efficiency of exchange should be at least 95% of volume and must be repeated three times. Vessels which demonstrate high-efficiency exchanges may reduce the number of exchange cycles.Ballast Water Exchange should only be undertaken when the safety of the vessel and crew are guaranteed. Ballast Water Performance In the case of Ballast Water Exchange, ship operators are flushing untreated ballast out of the tanks. This is a practical if not perfect way of allowing older vessels to operate without the expense and logistical problems of ballast water treatment retrofits. New and retrofitted vessels are much less likely to transport unwanted species because the ballast water treatment systems eliminate a large proportion of the viable organisms from the ballast tanks before discharge. Systems like these significantly reduce the chances of unwanted species being introduced by inefficient exchange practices or in the event of an untreated near shore discharge for safety reasons. The IMO uses the following guidelines for the Ballast Water Exchange standard in regulation D-2. Ballast water must contain less than 10 viable organisms which are greater than or equal to 50 microns in size per cubic meter (264 US Gallons). For reference, 50 microns is about half the thickness of an average human hair.In addition, ballast water must contain less than 10 viable organisms that are less than 50 microns but greater than or equal to 10 microns per milliliter (1/1000th of a liter).Indicator Microbes may not exceed the following amounts; Vibrio Cholerae - less than 1 CFU (colony forming unit) per 100 Ml, E. Coli – less than 250 CFU per 100Ml, Enterococci – less than 100 CFU per 100Ml. Water treated to this standard is considered pure enough to discharge in most ports. These steps to re-mediate ballast water are only effective in the removal of unwanted organisms. It is still possible to carry toxins like copper and heavy metals often found in ports to other destinations in ballast water and these pollutants may concentrate in ballast tank sediment. Radioactive substances can also be transported in ballast but any serious cases would likely be found quickly by monitoring personnel.

It was started in 1886 in Toronto as music school and had emerged as top school for piano. It had maintained its traditional approach to teaching. But by 1950s, University of Toronto gave it a stiff competition by its modern outlook and more professional way of working. The university gradually took over its traditional role of preparing concert stage musicians which led to the decline of RCM. These events were important issues that were raised in the text. Yes, Peter Simon was successful because he was able to turn around the declining status of RCM into successful institution with wide ranging activities in the field of music. He brought in corporate culture that used technology and innovation in the area of academics. A shift from academic to corporate culture broadly means that while academic is mainl y concerned with scholastic achievements, corporate culture is goal driven and strives to meet the challenges of time with new ideas and products. Higher performance outcome and financial gains become critical paradigms of success. I would advice Peter Simon to maintain high degree of ethics within RCM so that quality in music school is maintained. The online education must be accompanied by in-house training and practical tests. It would help to gain credibility amongst the various stakeholders like students, music teachers, donors etc. Knowledge sharing has increasingly become vital aspect of competitive advantage. I would therefore suggest Peter Flagstaff and Lindsay Gibson to create a learning environment that promotes knowledge share. Use of technology within the operations would greatly help to create a large database of new ideas and information that can be shared, as and when required. Effective management information system should also be developed so that management is abl e to monitor the projects and is able to give critical inputs to the accounts executives to save time.

Sustainability Written Report Essay Example | Topics and Well Written Essays - 750 words

Sustainability Written Report - Essay Example Originally, geothermal energy was used in hot springs as early as Paleolithic times according to a study made by Cataldi (1993) about the history of hot springs before the Modern Period. Technically, the first geothermal energy harnessed lighted a few light bulbs. The following accounts relate how the world recognized geothermal energy: On July 4, 1904, Prince Piero Ginori Conti tested the world’s first geothermal generator at the Larderello dry steam field in Italy. Merely a couple of years later, this invention was deployed commercially and used to operate drilling equipment. Soon the small town of Larderello was using geothermal power for all its electricity requirements. (History of Geothermal Energy, http://www.economywatch.com) Because of the said event, it is no wonder that Italy maintained the position as being a top producer of geothermal energy for many decades. New Zealand followed suit only fifty-years later. The United States took the risk and invested in the Geys ers Geothermal Field in California which is currently the largest producer of geothermal energy in the world. This location has five power plants and Chevron Corporation spearheads in providing geothermal energy to millions of American homes. Uses of Geothermal Energy Geothermal energy has many useful purposes, with electricity generation as its most widely-known use. Bioeconomicfuel.com cites the 5 different uses of geothermal energy (Stern, 2009): 1. Industrial and Agricultural Uses A good example of which is the role of geothermal energy in drying up timber. In New Zealand, the â€Å"Tasman Pulp and Paper Mill uses geothermal steam in heat exchangers to heat kiln air to 140?C for timber drying†( Stewart, 2009). Aside from timber, crops can also be dehydrated using geothermal energy which makes this type of energy very useful for agriculture. 2. Food Processing The food processing industry can harness the heat from geothermal energy for sterilization process as well as dryi ng. In India, Chandrasekharam (2001) published a paper that advocated the use of geothermal energy in food processing since India’s topography is viable for this type of food processing. However, the United States had already applied that concept way back in 1978 when it opened the geothermal food processing plant in Brady Hot Springs, Nevada. In fact, â€Å"More than 25 million pounds of dehydrated onion and garlic are now being processed annually in Nevada â€Å"(nrel.gov, Oct 2001). This fact just attests to the huge capacity of geothermal energy in providing clean energy at a lesser cost. 3. Electricity Generation The Geothermal Energy Market Report shows that in 2005 alone, the top ten countries used 97% of geothermal energy for electricity generation purpose (refer to Appendix A). According to the International Energy Agency, â€Å"geothermal energy currently supplies less than 1% of the world's total energy demand†. Nevertheless, it has an enormous potential t o mitigate climate changes by reducing the use of carbon fossil fuels. It is a considerable source of renewable energy. In the case of Philippines, (which is second to the United States in using geothermal energy), it has a potential to become one of the world’s largest producer of geothermal energy. Currently, geothermal energy supplies 27% of the country’s electricity (www.philippines. hvu.nl). During the World Geothermal Congress in 2000, it was declared that the â€Å"

Individual news article analysis Essay Example | Topics and Well Written Essays - 1000 words

Individual news article analysis - Essay Example As a direct result of these dynamic shifts, the manner in which marketing has taken place and the manner through which firms seek to reach their clients has also changed precipitously from what it was merely a few years ago (Jones et al. 691). Accordingly, the following analysis will seek to detail the ways in which technological change has not only shifted the means of marketing and integration, but has fundamentally changed the ways that businesses promote themselves and engage with the consumers in the market (Holmes et al. 124). The article points to the fact that many firms have been unduely tempted to step away from traditional approaches and have begun to chase the allure of cheap and omnipresent forms of internet advertising; to include those linked to social media marketing. Although this can most certainly be an effective approach in engaging certain key demographics, the author warns that it must not supplant the approach that it utilized within the many other forms of mar keting that have for so long helped to define the means by which businesses integrate with the consumers. ... mail, the communication platform that the mobile device now offers allows for a much greater degree of efficiency even if the individual in question is not within range of a Wi-Fi signal and/or within range of traditional desktop PC and keyboard (Hortinha et al. 28). Further, perhaps the greatest shift that can be noted outside of the sheer ease of communication that these devices have been able to provide is the fact that mobile marketing has been able to pervade the environment and can be exhibited to the individual upon nearly each and every website that is viewed in a mobile platform or even as advertisements that are provided within the applications that each of us have become so reliant upon (Ballve 1). With respect to the way in which the individual or the firm should integrate with the information that has thus far been presented, it must be understood that the zeitgeist of the era demands a closer attention is paid to mobile computing and the manner in which it can be utiliz ed to garner further levels of profitability for the industry/business in question. From the personal standpoint, little if anything has changed with regards to communication over the mobile platform in the past 5-10 years (Vasilchenko & Moorish 89). Once mobile devices became internet enabled and were functionally able to send emails/MMS messages as well as search the web, few innovations have come along to shift the dynamic of personal communication. However, with that being said, it must be understood that the greatest shift that has been felt with regards to mobile computing has been with respect to the way in which businesses seek to leverage these platforms as a means of reaching out to the consumer. One need look no further than a major car manufacturer’s television advertisement

Moreover, the research questions can support the research in its objective of achieving the possible answer to the thesis. The central research question in this proposed study what are the factors that help reduce on smoking rate. There are other research questions which support the leading research question. These are: There are six major research designs that can be used by researchers. Among these, the researcher shall settle with the use of survey research design. Generally, surveys entail a representative research whereby data collected from a group of people is generalized for a wider population base. The term survey is used widely in research work. It refers to the process of selecting a relatively large sample of people from a predetermined population in which the researcher is interested in. This process is followed by collecting a small quantity of the data out of the selected individuals. This information is then used by the researcher in making inferences concerning the wider population. In using the survey, collection of data are in a standardized form usually achieved through interviews or by a questionnaire. Surveys are always designed in away to providing snapshots of state of things at any specific time’. This strategy is suited to descriptive type of studies, although limit ed to aspects of a situation. The method has some disadvantages and advantages. These include: first, the research gives data that are based on empirical data secondly the coverage of many events implies more likelihood of some other approaches to obtaining data that are based on representative samples. This may be generalizable for a whole population. Thirdly, survey produces large data within a short time at a fairly low cost. This implies that researchers can come up with small time-span for a given

Stress Essay Example | Topics and Well Written Essays - 250 words - 1

Stress - Essay Example This kind of stress is experienced equally by administrators, managers, employees and workers. Segal et al (2008, para.2) assert that â€Å"while some stress is a normal part of life, excessive stress interferes with your productivity and reduces your physical and emotional health, so it’s important to find ways to keep it under control†. A little stress is beneficial, as it keeps one going and forces him to maintain his good performance. This is called positive stress. However, negative stress weighs heavily on one’s well being because one feels weakened enough to fight the hurdles (Volhard & Volhard, 2011). Behavioral effects of stress include discontentment, argumentative behavior, lack of attentiveness, lack of commitment to the job, and conflicts in relationships (Soreq, Friedman, & Kaufer, 2009, p.42). Physiological effects include headache, stomachache, slow digestion, obesity, decreased sex drive, blood pressure leading to coronary heart diseases, and var ious skin infections (Mayo Clinic, 2011). Before treating stress, it is important to rule out the possibility of factors that accompany stress. Segal, J., Horwitz, L., Jaffe-Gill, E., Smith, M., & Segal, R. (2008).

New business challenges in the Saudi market Thesis

New business challenges in the Saudi market - Thesis Example The objective of this research is to acquire a better insight business challenges in the Saudi market. Many emerging economies have been turning to their new businesses for economic growth. This has been the primary drivers of economic growth for most of the emerging and developing economies. Also, majority of the businesses in many countries worldwide are dotted with these new businesses. However, in Saudi Arabia, the performances of their new businesses have been very dismal. In fact, despite accounting for over 90% of their industries, these start-up companies only manage to employ less than a quarter of their labor force. As such, this situation has been believed to be a strong contributor to the high unemployment rate in the country. However, it seems that problems beyond entrepreneurship drives are pervasive in the country. In fact, there are many foreign workers in the country and statistics show that foreign male workers hold an even bigger chunk of employment than their Saud i counterparts. This has shown a more systemic problem in the country involving the education system of Saudi Arabia. Also, there should be an increase in the contribution to the economy from the private sector and the paper will attempt to explain the underlying problems affecting the new businesses in Saudi Arabia. Moreover, there policies of the country such as the Nitaqat and Saudization will be explored so as to shed more understanding into the possible solutions to the wanting contribution of the private sector in the country’s economy. ... The country is governed by a monarchy system of government and is a predominantly Muslim country. It is among the richest nations among the Arab states and this is mainly due to the oil that it exports. In 2010, the country’s oil fields churned out approximately 10.5 billion barrels per day (bbl) and so far, this has been the greatest source of revenue for this Arab state (CIA World Factbook, 2011 and Library of Congress, 2006). However, there is a growing need to diversify the sources of income for the government and basically, the country cannot forever rely on the public sector and its oil to be the only revenue generators for the country. Therefore, the country needs to encourage the strong growth of the public sector, especially the new businesses that will have to provide the necessary diversity to the Saudi economy as well as the needed boost for its economic growth. Although the country enjoy a relative prominence among its regional neighbours, the economic weakness of the country is seeping out reflected by the increasing unemployment in the kingdom. According to the ILO (2010), the global crisis that emanated from the deep recession among the advanced economies has adversely affected Saudi Arabia’s economy. Being among the world’s most voracious oil consumers, it is easy to see why the deep downturn in the advanced economies has greatly affected the economy of oil producers, most notably Saudi Arabia. The adverse effect of the economic turmoil that deepened the problem of unemployment in Saudi Arabia clearly demonstrates the lack of diversity in its economy since it is heavily reliant on oil. This commodity has been largely controlled by the state therefore it is easy to see why the public sector has been

A total of 1,500 questionnaires were distributed while 1,331 were completed and returned giving a response rate of 88.7%. The mean age was 30.0 + 5.0 years. Of these, 573 (43.1%) women had heard of preconception care. The respondents awareness of preconception care and their ability to define the subject correctly increase significantly with their educational status and age. The majority believed that preconception care might improve the health of mother and child. Objective-3: To find out the association between level of awareness regarding preconception care with their selected demographic variables-age, education, family monthly income, type of family, religion area of residence. In this study association was analyzed by using Chi-square between the level of knowledge regarding preconception care and selected demographic variables The findings of the study showed that there was significant association between the level of knowledge and their area of residence. The other demographic variables (age, education, type of family, family monthly income and religion) were having no significance with the level of knowledge. The statistical findings of association between level of knowledge and area of residence of the students was found to be statistically significant [à Ã¢â‚¬ ¡2 value=10.2016, Table value =.9.49 and df = 4 at 0.05 level] It evidences that there is significance between association of level of knowledge and area of residence of the students. This finding of the study was supported by another study conducted by Chacko, Anding, Kozinetz, Grover, Smith., (2003) objective of the study was to assess knowledge of neural tube defect prevention by folic acid among adolescent and young adult women. Results of the study showed that of 387 women (mean age: 18 +/- 1.9 years), 72% were black and 28% were Hispanic. 44% answered that clinics were a major source of information of neural tube defect prevention, 52% had heard of folic acid, 45% had heard of neural tube defect, and 50% had heard of birth defects prevention by folic acid supplementation. Result showed that more Hispanic than black young women had heard of neural tube defect (59% vs39%). Pregnancy history, regular birth control use, and education level for age were independently associated with knowledge. In young women with low education level for age, regular birth control use was significantly associated with knowledge. Proper folate diet was not associated with the knowl edge. The follow-up survey of the programme showed that 88% to 92% had the knowledge of neural tube defects and folic acid consumption.

Roe V. Wade Essay -- essays research papers

January 23, 2000 marked the twenty-seventh anniversary of the Roe v. Wade case. It all started out in a small town in Texas where a woman under the alias Jane Roe filed a case in district court for a woman’s right to choose abortion. At this time law in Texas prohibited abortion. Eventually the case moved to Supreme Court. The attorneys for Roe argued that the law was unfair and unjust.

William Blake was born in London on November 28, 1757 to James and Catherine Blake. His father, James was a hosier (seller of legwear) in London. Blake had four brothers, James, John, Richard and Robert; and a sister named Catherine (Harris 5). Blake got along best with his younger brother, Robert as they shared an interest in art (Clarke 1). As a young boy, Blake claimed to have had visions of God, spirits, prophets and angels. When he was four he is claimed to have seen God’s head in his window. In his most famous vision, he saw the prophet Ezekiel under a tree and a tree of angels when he was nine (â€Å"Early Years†). Though his parents believed he was lying, they took into consideration that their son was â€Å"different† and did not believe he would succeed in a traditional school setting (â€Å"Poets†). So Blake was home schooled by his mother until he was ten years old. Blake was constantly by himself as a boy â€Å"†¦to seek a world of the i magination without fear of recrimination by others† (Harris 21). As a child, Blake spent his time engraving drawings of the Greek antiquities his father bought for him â€Å"(Early Years†). James and Catherine supported and encouraged Blake’s artistic ability and enrolled him in Henry Par’s drawing school in the Strand when Blake was 10 years old, there he first started writing poetry (Harris 5). He enjoyed the works of Shakespeare, Jonson and Spenser and ancient ballads as opposed to current literature at the time (â€Å"The Young Artist†). Some of Blake’s favorite artists ranged from Raphael, Michelangelo, Giulio Romano, Albrecht Dà ¼rer, and Maerten Heemskerck. (Merriman 2) In 1772, Blake was apprenticed to the engraver James Basire the engraver to the London Society of antiquities, due to the high cost of dra... ...nius during the French Revolution, aware of impending economic change and sick to the bone of ruling hypocrisy †¦Ã¢â‚¬  (Hagstrum 97-98). Implications Charles Swinburne, Percy Shelly, T.S Elliot and James Joyce all drew their influence from Blake (Profumo 1). William Butler Yeats especially was inspired by his philosophical and poetic ideas and even edited an edition of Blake’s collected works (â€Å"Blake and Shelley†). Bob Dylan Alasdair Gray, Jim Morrison, and Allen Ginsberg also have hints of Blake’s poetry (â€Å"William Blake in Doors†). More recently his poems have modified by U2, Jah Wobble, Tangerine Dream, Bruce Dickinson, M. Ward and Ulver (Maher 4) . His poems have been inspiration for characters of a number of writers of the twentieth century. Blake has been the muse for comic book writers Alan Moore, Grant Morrison, R. Crumb, and J. M. DeMatteis (Whitson 1).

There were several issues that affect the mentally ill from gain employment such as education, support system, employer’s lack of knowledge of this population, discrimination, stigma, stress while being employed and dealing with multiple problem that occur at one time..The reason for this review is to focus on issues that would occur in prevent the mentally ill from maintain employment and for the individual to be more diverse while working alongside or with this population. Research was conducted on this topic and will be reflected in this review. History Having a source of income is important in someone life by having employment it allows them to be independent and also help them to obtain goods that better value their living. In September 2012 employment rate in United States rose by 418,000 to 155.1 and there were 802,000 discouraged workers in September, a decline of 235,000 from a year earlier. Discouraged workers are persons not currently looking for work because they believe no jobs are available for them (United States Department of Labor, 2012). This research shows how it is hard for someone who does not have a mental illness to obtain employment. The Center for Disease Control and Prevention reports mentally ill is at the bottom of the employment poll which was reported from the National Health Interview Survey (cdc.gov 2012, Loveland, Driscoll, & Boyle, 2007). Being in the workforce allow you to take care of your personal needs. It allows you to earn money and be active in society. In life this is how people determine who they are and what they want to be. The mentally ill are so afraid of revealing which they are that this might prevent them from obtaining employment. Emotion or feelings are difficult to evaluate because they often remain hidden (Bucher, 2008). Mentally ill are afraid to tell their employer or co worker that they suffer from mental illness because of fear of being terminated because of discrimination. .Carr-Ruffino(2005) defines discrimination as actions or practices that results in members of a less powerful group being differently in ways that disadvantage them. For example john told his employer he was taking medication for his mental illness. His employer response is that we don’t need people here like that. The employer was not being cultural diverse which would cause him to be sued. Diversity means being aware of your own and someone else’s cultural belief, religion, race, sexual orientation. En.wikipedia.org (2012) defines cultural competence as the ability to interact effectively with people of different cultures, ethnic backgrounds. Social workers should obtain education about and seek to understand the nature of social diversity and oppression with respect to race, ethnicity, national origin, color, sex, sexual orientation, gender identity or expression, age, marital status, political belief, religion, immigration status, and mental or physical disability (NASW, 2008). Individual who have mental illness already are being stereotype in the world and now being stereotype while looking or having employment is not diverse. By being aware of someone else we can better service ourselves and them. Wikipedia (2012) defines social stigma is the extreme disapproval of, or discontent with, a person on the grounds of characteristics that distinguish them from other members of a society. Stigma may attach to a person, who differs from social or cultural norms. Vogel & Haake, (2006) states stigma associated with seeking mental health services, therefore, is the perception that a person who seeks psychological treatment is undesirable or socially unacceptable. Wikipedia (2012) defines job as a regular activity performed in exchange for payment. A person usually begins a job by becoming an employee, volunteering, or starting a business. Employment improves self-esteem, satisfaction with finances, and has been associated with reduction of hospitalization rates and psychiatric symptoms (Johannesen, McGrew, Griss, & Born, 2007). â€Å"Research suggests that work improves self-esteem and well-being† (Gannon & Gregory, 2007). The mentally ill utilize work as belonging to something and a step to return to society without being stereotype. History has shown that the mental ill and employment has not been a major focus. In society we view the mental ill as the led fortunate and society expectation is that they would not work. Sociostructural b arriers and disincentives have also made it difficult for people with a mental disorder to get in and stay in the competitive workforce (Marrone JF, Follwy S, Selleck V., 2005). Individual with a mental illness has right to do anything that an average individual does in the workplace or in their personal life. In order for them to do this they would need a support system which would include job coach, counseling, therapy and housing. World Health Organization (2012) states, governments need to dedicate more of their health budget to mental health. In addition the mental health workforce needs to be developed and trained to ensure that all people have access to good quality mental health services at each level of the health care system. People who suffer from mental health issue are capable of working however the unemployment rate continues to rise. Trading Economic (2012) reports from 1948 until 2012, the United States Unemployment Rate averaged 5.8 Percent reaching an all time high of 10.8 Percent in November of 1982 and a record low of 2.5 Percent in May of 1953. The unemployment rate can be defined as the number of people actively looking for a job as a percentage of the labor force. Unemployment rates for people with serious and persistent psychiatric disabilities are the highest, typically 80-90%. (Crowther & Marchall, 2001). Employment among those with severe mental illness is much lower at eight percent (Gannon & Gregory, 2007). As a result, people with serious mental disabilities constitute one of the largest groups of social security recipients (Sanderson & Andrews, 2006). Individuals who suffer from mental illness and do not have a job will always be judged because of their illness and them not being employed. By the employer not being culturally diverse this stops the mentally ill from being employed and causes the employer to hire someone with out mental health issues. 2010disabilitysurveys.org( 2012) reports that Kessler Foundation and The National Organization on Disability found that little progress has been made in closing the employment gap between people with and without disabilities since the passage of the ADA into law. Reports have shown that many mental ill individual are employed a dead end job which does not have any advancement. Current reports from Kessler Foundation/NOD (2010) reports majority of employers, according to a 2010 survey, include flexible work schedules, telecommuting, and ergonomic redesign of workstations. This behavior is following The American Disability Act which states accommodation is any modification or adjustment to a job or the work environment that will enable a qualified applicant or employee with a disability to participate in the application process or to perform essential job functions. Reasonable accommodation also includes adjustments to assure that a qualified individual with a disability has rights and privileges in employment equal to those of employees without disabilities (ada.gov, 2012). Individual with mental illness are working alongside individual who are not diverse. They might be judged by their co workers after returning from treatment which causes the co worker to be biases. Most jobs that the mental ill obtain will end unsuccessful. A greater effort must be made to provide support networks for employees within their work environments (Nelson & Kim, 2012). Individual sometime keep their mental illness as a secret to avoid bad treatment at work which causes them not to use the employee benefits that are given. In order for the workplace to be diverse the employer must force diversity in the work place by having training for their staff. We make diversity work when were willing to imagine people from different backgrounds views the world and how theses people are view by others around them Carr-Ruffino (2005). Conclusion By being more knowledge of the mentally ill we can avoid being biases. We can avoid decimations and stigma in the workplace and in ourselves. Mentally ill should not have a reason to experience workplace inequity and direct prejudice due to past shortcoming because they are disabled. In order for the mental ill to keep employment they would need to have a treatment plan in place. Research has shown that there are still areas in dealing with the mental ill in the workplace but we as society also must be diverse. References Bucher, R. D. (2008).

All about me

The first thing that came to mind was the simple fact I was going to fall. I had to ask several questions before even completely understanding the requirements. We had to evaluate who we were, why we were here, and how Mr.. Wentworth could be of service to us. I worked for many days composing this essay; including many rough drafts and bad ideas. The first part of the prompt was by far the hardest, it took the most thinking. Preprinting consisted mainly of sitting around trying to figure out who I actually thought I was.I wrote about 3 rough drafts before deciding on how I was going to present myself. After finally liking one draft, I did numerous amounts of editing. The editing process was difficult for me because I did not want to mess up my very first essay and make a bad first impression. Revising the essay was much simpler with help from peers. The benefits of using a formatted writing process are ultimately what lead to my higher grade. This process helps to organize, edit, and write with ease during difficult assignments.To better organize I wrote many drafts and billeted list of important ideas to include, which helped to be sure I included all necessary points. Editing was made easier by my peers who read over the essay and gave me feedback from different perspectives to improve the flow ND structure of the essay. And lastly, the ease of writing the final draft came from this described process used. Without this process, I would've made a much worse grade and been more stressed out over trying to get it done.Who are You? The prompt of this essay was to write a declaration of independence from your parents, much like the Declaration of Independence written by our founding fathers. We were instructed to use more Latin based words as well as all of the rhetorical devices we studied in class. The goal of this assignment was to gain independence room our parental units and was a chance to explain our wants and needs in a professional way.We then had to read this essay to our parents in order for them to grade how well we did. Using a formal process to write this essay made it much easier to get our point across rather than Just writing without structure. Another process used as well was studying the format used by the founding fathers of our country. However, the traditional writing process helped in many ways to receive the grade I desired. Preprinting, the most important, helped me to figure out what I wanted to say and exactly how I would say it.

“It is through what we wear that we all establish our identity.” Briefly support or contradict this claim

Let us imagine a world where it was acceptable to roam the streets unclothed. Would you still conform to the norm that stated that it was usual to wear clothes? Most would, but there would be a minority who would take the liberty of going out naked. They would be viewed by the majority as anti-conformist and it could have spiralling effects on other aspects of their life – such as their identity. If a teenager wants to rebel against norms, it is very easy. They simply need to turn up to a dinner party in jeans and a t-shirt and no more need be done. They would have firmly set an impression in the minds of the other â€Å"black tie wearers†. It could lead to exclusion from the group even if they knew each other previously because it is showing a side of the person that may have previously been hidden. There isn't a human being who doesn't take appearance into account when getting a first impression of someone. It is what initially attracts one person to another and can give an idea as to what the person may be like. However, identity can be established in many ways and clothing is just one of these methods. When looking at a particular group of people, it is usually possible to examine the trends that they exhibit and spot people who look out of place and may be trying to change or enhance their identity through their clothing. Describe the connection between one particular trend in pop music and what its followers wear. â€Å"Mom. I wanna be just like Britney Spears† were the eight words which rang across the world when Ms. Spears released her saucy â€Å"Baby One More Time† video. Suddenly, it was trendy to dress in school girl uniform and the boys were instantly turned on by teenage girls dressing just like Britney. Had it not been for Britney's video, dressing in uniform at any time other than in lessons would, most likely, still be very â€Å"un-cool†. Since her first single, Ms. Spears has been an international jet-setter and trend setter. With each premiere, awards ceremony and after-show party she has attended, she has been the subject of miles worth of newspaper columns. Teenage girls everywhere have been unable to avoid the tactless and shameful promotion that Jive Records have elicited from Britney and living in the 21st century, it has become almost impossible not to be influenced by the publicity surrounding America's most famous Virgin. From controversy to contraception, Britney has been linked to everything. The initial hype surrounding her showed that she was popular amongst teenager boys and this was, no doubt, one of the main reasons thousands of teenage girls began to idolise her. Her sweet and innocent image meant that it was cool to be like Britney and this soon led to an explosion in mini-Britneys. There was a risk that she wouldn't catch on though and that she would fizzle out as another one-hit wonder. However this was soon disproved when she was pursued quickly by the other pop teen queen Christina Aguilera. Just when parents thought that Britney would be a temporary phase that their kids would go through, Christina pops up onto the scene. Bringing yet another set of catchy pop tunes, Christina enforced the idea that it was necessary to look gorgeous, be a size 8 and have a perfect body. Pig-tails were in and pony-tails were out; short skirts became even shorter and breast enlargements were being ordered left, right and centre. Despite their persistent denial of buying the plastic treatment, private clinics saw an enormous increase in their waiting list around Christmas time. It became cool to wear tight tops, to dress in leather and run around school doing Britney and Christina style dance routines. However, times change quickly and schoolgirls are already becoming bored of their teen idols' style and as Britney turns unfavourable in their eyes, it is now necessary for them to look at the older and more respected artists. Singers like Jennifer Lopez, Samantha Mumba and Janet Jackson who all have unparalleled style are the new trend. As teenage girls want to mature into appreciated women, their dress sense also proceeds in parallel and they begin to move away from the â€Å"bubblegum† image into a more adult look. They will however, all too often find themselves pre-occupied with the idealistic look of women in beauty magazines and on screen. Although this shouldn't be the case, it is an inevitable consequence of living in the midst of technology as we do and at least through these more mature artists, teenagers are growing up quicker. It is ironic to think that Britney is now modelling herself on her fans in order to please them. As they mature and advance in their ways of thinking and styles and trends, Britney is now evolving into a more mature and focused artist more in the style of Janet or Madonna. What is worrying though is that there doesn't seem to be another level to which artists like Britney can go to after her fans get tired of her present scheme. Unlike the real divas, Britney has a shelf life and it is almost up. Unless she can creatively reinvent herself with yet another new style, her fans will have to look elsewhere for inspiration and it may well be to an anti-conformist who exhibits qualities that are rebellious and not in line with conventional trends.

Networking - Statistics Project Example Moreover, tree topology facilitates the network administrator to expand the network easily. However, if the network expands, it becomes more difficult for the network engineers to manage the network. 2 Issues of Tree Topology As there is no centralized provision of services, it is difficult for the network engineers to tackle issues related hardware, software and network services. Physical intervention is required as the hub backs up each network segment, if the hub become nonoperational, the workstations of the entire department becomes unavailable on the network. Moreover, it is not necessary that each network segment is using the same cabling scheme (Chapter 5: Topology). Due to compatibility issues, cross cabling or straight cabling is required, consequently making difficult for network engineers to troubleshoot network issues. Moreover, due to separate network segments on the network, some network segments may become vulnerable to threats, as network administrators do not have a centralized access to the network devices. These considerations must be analyzed during the network design stage of an organization. 3 Network Infrastructure Recommended LAN topology is a star topology. As star topology shares many advantages, the most prominent one is the centralized administration and monitoring of the network. Moreover, star topology provides high data speeds along with easy installation of cables. Any component on the network can be removed or plugged in without any interruption. Likewise, centralized administration facilitates network administrators and engineering to detect issues and faulty components. Hubs may deteriorate network performance. As they can only operate on the maximum data transmission speed of 10 Mbps and copy data files to the designated... Recommended LAN topology is a star topology.

Moreover, star topology provides high data speeds along with easy installation of cables. Any component on the network can be removed or plugged in without any interruption. Likewise, centralized administration facilitates network administrators and engineering to detect issues and faulty components. Hubs may deteriorate network performance. As they can only operate on the maximum data transmission speed of 10 Mbps and copy data files to the designated ports, files that are larger will take time and may congest the network. However, cost of the hub is low as compared to a switch; it may affect the performance of the network. On the other hand, switches can improve network performance significantly. As switches can learn the MAC address of the sender, they create a management information base for storing all the MAC addresses of network nodes. This will eliminate the time taken by the switch to identify and learn MAC address of the sender. Moreover, switches can provide the overall network usage along with statistics related to access policies via the network. Switches only share a disadvantage of a high cost as compared to hubs. A simple definition of regenerative repeater is available in network dictionary which states it as â€Å"a device which regenerates incoming digital si gnals and then retransmit these signals on an outgoing circuit†.

Popular Culture Artifact Essay Example | Topics and Well Written Essays - 1750 words

Popular Culture Artifact - Essay Example The featured artifact is drawing of the iconic Former South African President and Statesman Nelson Mandela. The icon chosen for the portrait is the diamond. Diamonds have been salient features in contemporary popular culture. In 1938 the New York advertising agency of N.W. Ayers was commissioned to change public attitudes toward diamonds. The campaign was conceptualized to shift popular regard of diamonds as a scarce, expensive and very hard stones to a symbol of commitment and everlasting love. Thus in 1947 and Ayers advertising copywriter came up with the slogan "a diamond is forever". "As an N.W. Ayers memorandum put it in 1959: "Since 1939 an entirely new generation of young people has grown to marriageable age. To the new generation, a diamond ring is considered a necessity for engagement to virtually everyone."(Sut Jhally: Image-Based Culture: Advertising and Popular Culture -1990). In the featured artifact the diamond icon represents the immortality of what the featured person has come to stand for. The Portrait pictures Nelson Mandela who committed his life to fighting for the emancipation of South Africans out of the shackles of apartheid. What makes the diamond icon more appropriate in the assembling of this artifact is the eternality of the values of peace and equality. This is what Mandela fought for. These values like a diamond are forever. The banner text also contributes to manufacturing of meaning impact in the artifact. It denotes the that fact that coal and diamonds are formed in exactly the same variables, pressure and heat the only differentiating factor being that diamonds were subjected to more pressure and heat than coal. Again these associative meanings coalesce sound meaning in interpreting the artifact. The meaning in this aspect is drawn from the excruciating and extenuating circumstances in his struggle for human rights. The ordeal would either make him or beak him and as such the very circumstances that made some of his fellow citizens fall made a jewel out of him. The jewel as a crystal three dimensional gazing stock contributes to the whole meaning worth as it has become a popular symbol of excellence and invaluable worth. The artifact employs the meaning dissemination channels provided thorough the conventions and inventions formula. Through the conventions the artifact taps into the significance of mundane appreciation of art, mere drawings of people, great and non-entities as well as objects. Drawings have an intricate appeal to human art appreciation. The Mona Lisa drawing by Learnado Da Vince is arguably the most popular and famous portrait. What has made the artifact famous is the fact that the immaculate masterpiece was hand drawn. The artist used his finger to originate the painting. Drawings as medium are valuable for their appeal to human senses as they express human prowess in creativity and reproduction of reality. The featured artifact, by virtue of being a hand drawn artifact, will effectively prompt recipient appreciation by its nature demonstrative of the human artistic dexterity. This aspect will also be enhanced by the fact that the drawing pictures a prominent international icon. Nelson Mandela is more than just an international celebrity;
