Chelicerates (Chelicerata)

Chelicerates (Chelicerata) Chelicerates (Chelicerata) are a group of arthropods that includes harvestmen, scorpions, mites, spiders, horseshoe crabs, sea spiders, and ticks. There are about 77,000 living species of chelicerates. Chelicerates have two body segments (tagmenta) and six pairs of appendages. Four pairs of appendages are used for walking and two (the chelicerae and the pedipalps) are used as mouthparts. Chelicerates have no mandibles and no antennae. Chelicerates are an ancient group of arthropods that first evolved about 500 million years ago. Early members of the group included the giant water scorpions which were the largest of all arthropods, measuring up to 3 meters in length. The closest living cousins to giant water scorpions are the horseshoe crabs. Early chelicerates were predatory arthropods, but modern chelicerates have diversified to take advantage of a variety of feeding strategies. Members of this group are herbivores, detritivores, predators, parasites, and scavengers. Most chelicerates suck liquid food from their prey. Many chelicerates (such as scorpions and spiders) are unable to eat solid food due to their narrow gut. Instead, they must expel digestive enzymes onto their prey. The prey liquifies and they can then ingest the food. The exoskeleton of a chelicerate is a hard external structure made of chitin that protects the arthropod, prevents desiccation, and provides structural support. Since the exoskeleton is rigid, it cannot grow with the animal and must be molted periodically to allow for increases in size. After molting, a new exoskeleton is secreted by the epidermis. Muscles connect to the exoskeleton and enable the animal to control the movement of its joints. Key Characteristics six pairs of appendages and two body segmentschelicerae and pedipalpsno mandibles and no antennae Classification Chelicerates are classified within the following taxonomic hierarchy: Animals Invertebrates Arthropods Chelicerates Chelicerates are divided into the following taxonomic groups: Horseshoe crabs (Merostomata) - There are five species of horseshoe crabs alive today. Members of this group live in shallow marine waters along the Atlantic coast of North America. Horseshoe crabs are an ancient group of chelicerates that date back to the Cambrian. Horseshoe crabs have a distinct and unsegmented carapace (hard dorsal shell) and a long telson (a spine-like tailpiece).Sea spiders (Pycnogonida) - There are about 1300 species of sea spiders alive today. Members of this group have four pairs of very thin walking legs, a small abdomen, and elongated cephalothorax. Sea spiders are marine arthropods that feed on nutrients of other soft-bodied marine invertebrates. Sea spiders have a proboscis that enables them to obtain food from prey.Arachnids (Arachnida) - There are more than 80,000 species of arachnids alive today (scientists estimate that there might be more than 100,00 living species). Members of this group include spiders, scorpions, whip scorpions, ticks, mites, pseu doscorpions, and harvestmen. Most arachnids feed on insects and other small invertebrates. Arachnids kill their prey using their chelicerae and pedipalps. Sources Hickman C, Roberts L, Keen S. Animal Diversity. 6th ed. New York: McGraw Hill; 2012. 479 p. Ruppert E, Fox R, Barnes R.

Analysis - Case Study Example Notably, all investments are marveled with investment risks that must be handled in a given way; otherwise, the affected business is headed to collapse. Risk management skills are learned. Therefore, such skills follow a given professional way since they often apply varied different models of problem solving skills. For instance, the discretionary wealth hypothesis is a perfect model of comprehensive risk management comprising of both interim shortfall constrains and downside risks that are based on ln(w-c) utility. Therefore, every business risk scenario follows a different and distinct way of management or handling. The Jarrod Wilcox’s article, Risk management: Survival of the fittest has represented different scenarios that require different and distinct risk management skills to handle. The first case scenario, Option income funds, is where brokers owned and distrusted stocks or bonds. Moreover, they distributed premiums in forms of income (Wilcox, 2004). These activities led to an intense disappointment and withdrawal of investors following gradual decline of opportunity and reduction of money flow. To build the investor confidence is this case; the risk manager should apply the Kelly’s rule of the stock portfolios. In this case, the investor should confront single period return distributions. By calculating statistical parameters such mean and variance thereafter looking into kurtosis and skewness of the date in distribution data, it is possible to predict the data distribution. This process will enable mangers to restrict or regulate rockers’ distribution habit thereby building the investor confidence (Wilcox, 2004). The Extreme CPPI case desires to protect the investor from the downside risk in order to reduce portfolio insurance. In other words, the case reflects a scenario where investors are only interested in business when profits are high. Despite timings, the investor may sometime

The Virgin Komi Forests Essay Example | Topics and Well Written Essays - 1500 words

The Virgin Komi Forests - Essay Example However, there are a number of threats to the Forests, including illegal logging and gold-mining, which could cause irreversible damage to the area and the loss of species. This paper aims to illustrate the natural diversity of the area to convince you to provide money for the support of conservation programs in the Virgin Komi Forests. The Diversity of Life As previously mentioned, the Virgin Komi Forests are an incredibly large virgin forest, and encompass a number of important and iconic species. The grey wolf (Canis lupus) inhabits the area, and was once the world’s most widely distributed mammal but is now extinct in a number of areas. Most significantly, the grey wolf used to inhabit a huge amount of territory in Europe, and thus a safe ecological zone within Europe may be of great benefit in protecting this species. The wolverine (Gulo gulo) is also present in the Virgin Komi Forests. Although the wolverine is classified as ‘least concern’ by the IUCN Red L ist, this may be in part due to the fact that it is still common in North America. In Europe, however, trapping and habitat fragmentation have reduced the range of the wolverine and they are now absent in many of the areas in which they were once present. Again, a European protection area for this animal may be of great benefit (Bobretsov & Yakushev, 2008). Although these species are important, there are a number of further species which are classified as rare or endangered by the IUCN Red List. The Ural Mountain anemone species Anemone uralensis is also under threat in the area, mostly because of flooding and human agricultural efforts. The artic sorrel plant is also declining in the area, in part because of its use in Russian soups and in part because of the changing environment of the Forests. The Ecology of the Forests The aforementioned wolverine and grey wolf are just two of the important animals in the area, both of which have been greatly affected by the habitat fragmentatio n common in other parts of Europe. Protection of the Virgin Komi Forests should, therefore, not just focus on saving this creatures but the habitat in which they live, including a number of tree species which are necessary for their livelihood. The black woodpecker (Dryocopus martius) is an example of a bird species in the area. These birds rely on tree species in the Virgin Komi Forests, such as the fir (Abies sibirica) and the Siberian larch (Larix sibirica) for their nesting sites and food (Kuuluvainen, Syrjanen & Kalliola, 1998). The black woodpecker also plays an additional ecological role, in that they abandon the holes they have made in the tree bark, which can then become important nesting sites for the smaller birds in the area. The Eurasian beaver (Castor fiber) is also found in the Virgin Komi Forests. Beaver species are often important keystone species within their environment for a number of reasons. Firstly, beavers are involved in the creation of wetlands which can he lp to increase biodiversity, as well as providing a suitable habitat for other species. Beavers are also involved in tree coppicing, which again alters the natural habitat and provides tree cover for other species. Finally, beavers also play in important role in protecting fish species because their dams trap sediment and improve water quality (Gawthrop, 1999). Although the Eurasian beaver is of

Global Perspective on Health Policy Essay Example for Free

Global Perspective on Health Policy Essay Introduction A macro perspective on health policy issues can be helpful to identify how problems become policy issues and how these issues result in the creation of health care policy. The neglected epidemic of Chronic Disease also known as non- communicable diseases are a controversial issue that needs to be addressed in the world. In this paper, the writer will provide an explanation of how this issue has resulted from a policy’s creation. Identify the steps in the state and federal policy development process. Furthermore, differentiate between policy development and implementation. Also, explain how stakeholders become involved in the process and why their voices often become a driver for change in health policy. What is Chronic Disease? Non-communicable diseases (NCDs), also known as chronic diseases are not transferred from person to person. They are slowly progressed over time. The four main kinds of non-communicable diseases are cardiovascular diseases such as strokes or heart attacks, any type cancer, chronic respiratory diseases like chronic obstructed pulmonary disease and diabetes. Other Chronic Diseases that affect many Americans are, Obesity and Overweight, Asthma, Epilepsy, Food Allergies, Glaucoma, Alzheimer’s, and Heart Disease (Non-communicable diseases. 2014). A Chronic Disease is a long-term illness that can be controlled, but not healed. The worldwide population is affected by chronic diseases. In the United States, chronic disease is the leading cause of disability and death that accounts for 70% of all deaths. Out of these premature deaths, 90% effect low- income and middle-class population. The World Health Organization shows that chronic illnesses are also the main reason for untimely deaths everywhere, even in places where communicable ailments are widespread (What is Chronic Disease?. 2011). According to the article, chronic disease is the most preventable and can be successfully controlled, and they are also very costly health issues and the most common. With the proper care and treatment, these long-term diseases can be controlled (What is Chronic Disease?. 2011). The Epidemic of Chronic Disease In today’s society, Chronic Disease is responsible for an enormous percentage of diseases in people. Non-communicable diseases affect all regions of the  world and age groups. People before the age of 60 attribute to 9 million of the deaths associated with chronic disease. Even though Chronic Disease are a huge problem in low-income areas, these diseases and risk are not exclusive to more wealthy Americans (Horton, R. 2005). The most vulnerable to the risk factors that contribute to chronic diseases are adults, elderly and children. Studies prove that it comes from unhealthy diets, exposure and use of tobacco products, not regularly exercising and harmfully using alcohol. Non-communicable disease are driven by aging and the globalization of unhealthiness in our lives (Non-communicable diseases. 2014). The globalization of unhealthiness like eating unhealthy can result in high blood pressure, overweight and obesity, high blood glucose levels, and higher blood lipids. Many of these risk factors can be lead to cardiovascular disease, which is a common NCD (Non-communicable diseases. 2014). The Center for Managing Chronic Disease (CMCD) aims help in the effectiveness with management and prevention in chronic disease. The main goal of CMCD is to help people at risk, or that are most vulnerable. Conducting advanced research and publicizing the results to aid in policy change and practices (What is Chronic Disease? 2011). On September 2011, a meeting with the UN High Level on Non-Communicable Diseases was an exceptional chance to produce a sustained global drive contrary to preventable disease and disability, premature death for chronic diseases, like stroke, cancer, heart disease and respiratory disease and diabetes. This is an increasing global threat in NCDs that is a barrier to developmental goals. These development goals include health equity, poverty reduction, human security and economic stability (The Lancet. 2011). Policy Making Process. In healthcare, Chronic Disease epidemics cause many threats to the world. In response to the crisis, The Lancet NCD Action Group and the NCD Alliance has proposed five priority actions. Which are: â€Å"Leadership, prevention, treatment, international cooperation, and monitoring and accountability—and the delivery of five priority interventions—tobacco control, salt reduction, improved diets and physical activity, reduction in hazardous alcohol intake, and essential drugs and technologies (The Lancet. 2011).† The import involvements were chosen for their health paraphernalia, cost-value, small costs of implementation, and political and financial achievability. Tobacco control  is the most urgent and immediate priority. They have propose a goal for 2040 that in essence the world would be free from tobacco where fewer than 5% of people engaged in tobacco use (The Lancet. 2011). Policy problems are identified by many factors that include methods that include getting issues on the political agendas and removing them. The first step in the Policymaking Process is agenda setting. Agenda setting is all about decision-making in the first phase of the policymaking process. To be considered on the agenda, difficulties must arise to policymakers’ attention. Healthcare problems are highly visible, because the affect the nation, whereas major problems no relating to health are considered invisible to make the agenda (The Lancet. 2011). The Policymaking process discusses the precise decisions and procedures that are required for a policy to be considered, proposed and implemented. This process is an interactive progression with various points of access that provides opportunities to impact the many decisions (Politics and the Policymaking Process. n.d.).Policymaking process is an interactive process with several points of entree that provides chances to influence the decision-making processes involved in each of the stages. Furthermore, there are three phases of policymaking: the implementation phase, the formulation phase, and formulation phase (Politics and the Policymaking Process. n.d.). Policy development and implementation. During Policy Development, policies may be developed and applied at several stages and may vary from formal reg ulations and legislation to the informal procedures by which governments function (Policy Development. n.d.). An example of policy development would be in government policy that is related to youth, children and health developed at national and federal; territorial and provincial; community, local and district; or international levels by elected executives transversely with a quantity sectors that includes education, health, social services, finance, recreation and labor. Additionally, policy development time frame is determined by various factors that include government agendas and media attention. (Policy Development. n.d.). On the contrary, Policy implementation involves putting implemented policies into play. Success from implementation is depends on three essential elements. First element is the state or president and government officials locally, must pass down polices to the proper agency with the government bureaucracy (Policy Implementation   Boundless Open Textbook. n.d.). The second element that is essential to policy implementation is strong interpretation. Meaning that legislative intent need be deciphered into functioning guidelines and agendas. The concluding element necessary in operative policy implementation is also challenging to achieve. Dedication of assets to implement policy beneath the primarily element must be combined with organization of the policy with enduring processes (Policy Implementation Boundless Open Textbook. n.d.). Stakeholders in Healthcare. A Stakeholder involvement in planning, management policymaking has be brought on by new general development models. These models seek a different role for each state based on consensus, pluralistic structures and political legitimacy. Stakeholder contribution can be categorized into three forms: cooperative, instructive and consultative (Involving Stakeholders in Aquaculture Policy-making, Planning and Management. n.d.). In Cooperative involvement primary stakeholder act as companions with government in the decision processing. Consultative involvement is where government makes the primary decisions and stakeholders still have influence in the outcome and processes. Last, in Instructive involvement the government makes the choices but apparatuses occur during information interchange (Involving Stakeholders in Aquaculture Policy-making, Planning and Management. n.d.). Conclusion. The macro perspective on health policy issues can be helpful to identify how problems become policy issues and how these issues result in the creation of health care policy. Chronic diseases impact the healthcare industry in many ways. This controversial issue impacts all age groups. The Center for Managing Chronic Disease (CMCD) helps with management and prevention in chronic disease. This paper, provided an explanation of how the epidemic of Chronic Disease has resulted from a policy’s creation. Moreover, identified the steps in the policy development process. Furthermore, differentiated between policy development and implementation. Also, explained how stakeholders become involved in the process and why their voices often become a driver for change in health policy. References What is Chronic Disease?. (2011).

Changing the Stereotypical View of Native Americans in the Movie, Dance

Changing the Stereotypical View of Native Americans in the Movie, Dances With Wolves The movie Dances With Wolves begins with John Dunbar in the medic tent awaiting his leg to be cut off because of an injury and the fear of it getting gangrene. He manages to keep it when the doctors say they are too tired to work on another patient. Dunbar then decides that he wants to keep his leg when he sees one of the other soldiers hobbling around. After leaving the tent, he found that there had been no push by either side in the battle they were in, so he decided to ride a horse right in front of enemy lines in an attempt to get it started and to die. He rode twice, but neither time got shot. When he arrived back at his home line, he was a hero and was granted the horse he rode and was permitted to go to any post he desired. Dunbar had always wanted to go west to see the frontier so he requested the farthest west post. In preparing to go on the trip, he found that a soldier going out there is to be an "Indian fighter." There was a wagon driver who was willing to take him out to the post, but he annoyed Dunbar. On the way out, they saw human skulls and demolished wagon, which put a little fear in Dunbar. On arriving, Dunbar found no one there. The wagon driver tried to convince him to go back with him but Dunbar refused saying that that was his post. They then unloaded the wagon and stocked the building with the supplies. Then, as the driver was going back home, he as attacked by some Indians and killed. Dunbar stayed at the post and did some repairs and explored the surrounding area. There was a wolf that came around now and then to watch which eventually became Dunbar's companion. During this time a few Indians visited him. A... ...he entire animal leaving no waste. Another is by showing how the white men treated each other and the Native Americans. How the whites would be cruel to the Native Americans just because that was who they were. The Sioux however, were not violent or cruel to Dunbar just because he was white, but were cautious and fearful of him at first. Once they got to know him, they were more open to him willing to accept him as their friend. This movie seemed to change allegiance from the white European Americans to the Native Americans rather successfully and effectively changing the stereotypical view of Native Americans by showing which group was actually the cruelest. It demonstrated it by showing which group was the invaders and which group was the invaded. It also demonstrated this by showing how each group lived and interacted with each other and those around them.

Colombian Immigration to America

Colombian Immigration to America Nicole University Of Phoenix ETH/125 Katherine Ruberto In the early nineteenth century the first known Colombian immigrants settled in New York City. Among these immigrants were nurses, accountants, lab technicians, and pharmacists. The Colombian Civil War called â€Å"La Violencia† of 1948 where more than 250,000 people were killed in total after the popular presidential candidate Jorge Eliecer Gaitan was assassinated forced many to flee Colombia and settle in America. The ongoing struggle with Colombia’s government and the recession also pushed many Colombians to migrate. Between 1960 and 1977 about 116,000 Colombians came to America. Because of the signing of the Immigration Act of 1965, Colombians as well as other potential immigrants of other countries were brought to a halt when there was a limit placed on how many visas were handed out. The fact that visas were limited to only 20,000 visas per country a year along with the high unemployment rate in Colombia put pressure on many families. Colombians that were able to come to America on a temporary based visa became illegal because they stayed beyond the allotted time. As a result the rate of undocumented immigration soared: estimates of those living in the country without permanent residency status ranged from 250,00 to 350,000 in the mid 1970s† (Sturner, n. d. ). The Immigration Act of 1965 was later revised to allow more visas to be issued. Colombians settled throughout the country in areas such as New York, New Jersey, Chicago, San Francisco, Houston, and Washington D. C. The late 70s and early 80s brought many Colombians to Miami, Fl. that is a city that thrives on Hispanic cultures and is very accepting of immigrants. Miami is a city that most people will speak Spanish before they even speak English, so for immigrants this allowed them to communicate and learn skills easier than in other parts of the country. The 80’s and the 90s proved to be a tough time for Colombians. America became more advanced technology wise, therefore the work immigrants performed was no longer needed. Another factor hitting Colombians hard was the recession of 1981. Americans felt that immigrants were a financial burden on the country and it became a pressing issue. As the Guerilla violence escalated in Colombia more Colombians fled to America. During that time, my mother had been traveling to New York to visit her father and I was born there practically by accident because I was suppose to be born in Colombia. My family suffered a tragedy when two of my uncles were murdered and we received threats not to go to the police or they would take every family member out. I am the only one from my family that was born a U. S. citizen, but I recall when my mother would have to tell people that I was an American Citizen in order to receive my health care and other things. It was like people looked at me differently because I had a Colombian last name. When I was young my mother made it a point that I learn English since I was about four years old because she knew that America was very discriminating against those that do not speak English. My mother knew first hand how limiting it is to have a degree in another country that is not worth anything here. My grandmother was a detective in Colombia, yet when we came here she had to clean houses because that career was worthless here. Because we came during the escalating drug war that was going on, we did feel that people stereotyped us. Even today when I tell people where I am from, they say an ignorant comment about my country and the drug that it is mostly connected to. People do not know how many lives and families were innocently ruined because of a war that is uncontrollable and is still going strong today. Because of the resentment from the American Society felt towards immigrants Proposition 187 was passed which denied health care, education, and other services to undocumented immigrants. In 1999 the federal court ruled that Proposition 187 was unconstitutional and their decision was not appealed by the state of California. I would say that I culturally identify with my Hispanic roots because it is attached to my family. We all want to preserve our family roots and values so that we can pass them on to our future generation. When my family comes together we cook Hispanic food and listen to Spanish music. Colombians are known to speak the best form of Spanish, which is known as â€Å"Castellano† and we have a heavy accent. For my family it has always been important that we preserve the language since we are around many other Hispanics and we tend to pick up their form of Spanish. In â€Å"Castellano† the words that we use are very different from the Spanish that a Cuban or Dominican would use. I love the American mainstream culture because I have spent the majority of my life here and grew up listening to Britney Spears, and watching Boy Meets World, and Full House. America is a great country for opportunity and although I was born here, whenever anyone asks me where I am from, I always smile proudly and say, â€Å"I am Colombian. Reference Page †¢Berube, Myriam.

Decantation Definition in Chemistry

Decantation Definition in Chemistry In everyday work, the term decantation is usually associated with wine. Decanting is also a chemical laboratory process used to separate mixtures. Decanting is a process used to separate mixtures, and ii its simplest form it just means allowing a mixture of solid and liquid or two immiscible liquids to settle and separate by gravity. This process can be slow and tedious without the aid of a centrifuge. Once the mixture components have separated, the lighter liquid is poured off leaving the heavier liquid or solid behind. Typically, a small amount of the lighter liquid is left behind. In laboratory conditions, small volumes of mixtures are decanted in test tubes. If time is not a concern, the test tube is kept at a 45 ° angle in a test tube rack. This allows the heavier particles to slide down the side of the test tube while allowing the lighter liquid a path to rise to the top. If the test tube were held vertically, the heavier mixture component could block the test tube and not allow the lighter liquid to pass as it rises. A centrifuge can greatly increase the rate of separation by simulating a great increase in the force of gravity. Some Mixtures That Can Be Decanted Oil and water  Ã¢â‚¬â€œ Oil floats on top of water. Decanting the mixture allows the oil to be poured off the water.Gasoline or kerosene and water –  This mixture is an example often cited as a safety hazard. Decanting a mixture containing flammable solvents can be dangerous as the flammable material evaporates and forms dangerous fumes.Dirt and water –  Muddy water can be cleared up by decanting. The soil will sink to the bottom of the tube allowing the clear water to be poured off.Wine –  Sediment from the fermentation process can produce an undesirable taste. Wine is decanted to separate the wine from these sediments.Cream and milk –  Cream is separated from milk by decantation. Cream rises to the top of the milk mixture and is easily skimmed off.Blood and plasma –  A centrifuge is necessary for this decantation. Plasma can be removed from blood by decantation.

10 Things Not to Say in a Job Interview

10 Things Not to Say in a Job Interview Job searching can be incredibly stressful. You’ve been anxiously sending out applications and now you have an interview, which is great! But you’ll want to make sure you don’t fall victim to any of the major faux pas of interviewing. Show you’re the right person for the job without waving any of the worst red flags. When in doubt, try to avoid the following 10 things.1. !!Salty language  just reads like amateur hour. Of course, everybody swears, but these words are best kept out of professional situations- particularly interviews. Likewise, you’ll want to keep any negative or bigoted speech off the table as well.2.  Ã¢â‚¬Å"My current boss is the  worst.†Your last boss was empirically awful, and you hated them. No matter how much righteousness is on your side, it’s best to refrain from boss-bashing to your potential new boss. It comes across as griping, and your interviewer will assume you just have a bad attitude- or that you were the one who was difficult to work with, not your former boss. If asked about a contentious boss situation, try and put a positive spin on the relationship by focusing on what you learned and how you grew.3.  Ã¢â‚¬Å"I am the best, because I know everything.†There are lots of ways to enumerate your many accomplishments without coming across as arrogant and using too many â€Å"I† statements outlining your greatness. If extreme confidence is just part of who you are, find a way to check it for the purposes of the interview.4.  Ã¢â‚¬Å"I’ll do whatever, in any position. It doesn’t matter.†You may think you’re being open minded and helpful by saying you’ll â€Å"do whatever!† but really you’re just showing that you lack a specific passion for the work of that company or industry, and a lack of awareness as to what sort of role you could best play. Target your search to jobs you think you’d be uniquely qualified to pe rform, then sell that in the interview, specifically.5.  Ã¢â‚¬Å"I  need this job or I won’t be able to pay my rent!†Ã¢â‚¬Å"If I don’t get this job†¦Ã¢â‚¬  is not a good way to start a sentence in an interview situation. There is no way to guilt an interviewer into giving you a job. Don’t even try. Get the job on your own merits and you’ll be a whole lot happier in the long run.6.  Ã¢â‚¬Å"So what is the exact title and who are you?†Don’t go into an interview situation without knowing exactly who you’re speaking with and exactly what the position is you’re being considered for. Ban the phrase â€Å"what job is this again?† from your vocabulary.7.  Ã¢â‚¬Å"So as a baby, I was very hard working †¦ and then in first grade †¦ and then in middle school†¦ â€Å"You’ll want to be as articulate as possible. Don’t give one word answers, but don’t get lost in run-on sentences or soliloquies either. Try to practice a few responses to questions you might reasonably expect to be asked. Keep each one under a minute, with just enough detail to help you stand out from the crowd.8. â€Å"Well, I’d say my biggest flaw is my obsession with being perfect.†No, perfectionism is not your greatest weakness. A hiring manager will see through this- the oldest play in the book- as a lazy clichà ©. Come up with something more honest that can lead you to a better discussion of how to learn and grow constructively.9. â€Å"How many vacation days do I get?†It’s perfectly reasonable to inquire as to the details of your compensation package. But focusing on these things too much, especially in a first interview, is a huge no-no- you’ll risk sounding like you won’t actually be interested in doing any work.10. â€Å"Sorry.†Ã¢â‚¬Å"Sorry I’m late† is something you should never say. First of all, you should never be late in the first place. Second of all, try to avoid having anything to apologize for. Be prompt or early, well-presented, put together, and prepared and you can do no wrong.

How have the different types of propaganda (white, black, grey) been Essay

How have the different types of propaganda (white, black, grey) been used to manipulate opinion - Essay Example In this context, two views can be positioned in contrast. The first is the view of the civil libertarian, which posits the rights of the individual to be most important and subsequently seeks to maximize individual freedom and minimize State control of all activities pertaining to life, liberty, and the pursuit of happiness. In contrast to this are societal forces, fascist in their most extreme form, that seek organization to limit and control others as a form of governance, either for minority social, cultural, and economic interests or for personal gain, power, ego, and other self-motivating factors, often using organized political violence as a tool to further ideological ends. Control is opposed to liberty, but organization in this context is ironically more associated with the controlling aspects of power than freedom as historically conceived. Indeed, as societal structures such as those in the military and government agencies of superpower States grow to unprecedented technolo gical and economic prowess, the absence of such agencies of control still exemplifies the libertarian approach. Within this duality is the traditional duel between Marxist critics and the apologists of Capitalism, with the â€Å"Western† ideal firmly based in the historical tradition of Greece and Rome, including both democracy and imperialism in the ideal Republic. In the context of critical theory and post-modernism, the historical approach can be used to deconstruct architectures of power to delineate types of State control through the analysis of media operations and propaganda techniques found both in totalitarian regimes and liberal democracies, to see what joins and differentiates the two approaches to government and media communications. The initial discussion of personal bias and political ideology when constructing an ideal by which to judge a process such as government communications or the proper end goals of society highlights that absolute objectivity or complet ely dispassionate review is not entirely possible in the context of political analysis, contrary to the appearance of historical fact. In order to judge and analyze the activities and processes involved in media operations of governments, there must be an a priori establishment of legitimacy and this inevitably involves a decision that introduces political bias into the argumentation. As such, the humanistic context of shared social and cultural values are assumed to be the base from which â€Å"true† judgment proceeds, as these are viewed as the best of historical values shared by diverse cultures across numerous countries in the course of the evolution of civilization, as well as those that are the most fair, egalitarian, and progressive for building the future of mass-society. Yet, at the very moment when these ideals are viewed as universal, critical inquiry based in Marxist philosophy particularly challenges whether these so-called Western ideals of supposed Greek and Ro man origin are really truth as universal and divinely ordinate, or actually another form of propaganda masking the â€Å"true†

NGOs are an effective force in processes of conflict resolution and Essay

NGOs are an effective force in processes of conflict resolution and healing. Discuss using examples - Essay Example The cause of violence in schools is caused by peer influence that is becoming a more compelling influence upon social acceptance and rejection, parental attachment show a stronger statistical relationship with hostility and delinquency (Dodge & Somberg 1987). Human beings have always been influential in finding the most effective ways to resolve conflicts or crime in the society. The advent of the criminal justice system was the consequence of similar efforts and the experiences shows that the formal system of criminal justice, due to many reasons, has not been fully successful in achieving its mandate in most countries. Mounting court arrears, delay in case disposal and consistent rising rate of acquittals has resulted in the loss of public confidence in the system. Furthermore, it was felt that the victims of crime who are to be in the center are usually sidelined in the criminal justice process. Whichever the outcome of the court case, the victim does not get any considerable gain to mitigate his/her victimization and nothing will help to restore and repair the damage caused. In the search for alternative to litigation, it would be a necessity to dwell on those judicial process facets which promote the capability of the system to dispense the expectations that judges and courts render justice objectively and impartially. This paper tends to seek to explain the role played my mediation as a traditional way of resolving conflicts in today’s society that replaces court of law. Moreover, this paper seeks to explain deeply the mystery behind mediation as a tool to resolve disputes over the years. In the end, the goal is to provide a clear and better support for the ongoing and future mediation efforts in peace processes. Discussion Mediation is the process of third party intervention in the case of environmental disputes between two or three parties who are on a disagreement. Its characteristics include voluntary participation and agreement as well as conf idential. United Nations (2008) explains that third parties are organizations or organization called upon or has volunteered to manage or settle issues between conflicting parties. Mediation is known to be a mystery and most of the peace processes are a success story while some are dismal failures, and most are a combination of the two. This process is extremely complex and difficult as one has to help in transition of a society from war to peace taking in to consideration the fact that the parties in conflict use military means to attain their objectives. It gets even worse when it can result in the killing of thousands or more in the process. During mediation, dispute parties may start to realize that they can gain a lot from negotiation than from fighting. This, however, takes time as the mediators needs to also understand their intentions and motives, and why they chose use of arms in settling disputes (Mrcela 2009). The role of mediation/mediator Mediation is usually appropriat e for settling disputes like those brought about by both verbal and behavioral message misinterpretation, communication problems, personal conflicts, harassment and deception (Mrcela 2009). In special cases, mediation can be used to resolve disputes between work groups or trade unions, or management on one end and employees on the other end. An example is in Slovenian organizations where
