Labor Relations in Different Organizations in The United Arab Emirates Essay

Work Relations in Different Organizations in The United Arab Emirates - Essay Example The accompanying paper examinations, sorts of work allows, the various classifications of infringement, and the human privileges of workers in the UAE. A glance at the Dubai bank likewise gives contribution on the above issues (Allah 1978, p. 78). The start of 2011 saw the presentation of work allows in the UAE by means of the Cabinet Resolution No. 25 of 2010. They incorporate; work move, brief, low maintenance adolescent people and staff supported by family work grants. The work move license covers non-nationals working in the UAE moved between associations inside the UAE of which must be enrolled by the Ministry of Labor. Impermanent work licenses, then again, spread both national and non-national faculty chipping away at an undertaking for under a half year. Low maintenance work grants spread people working low maintenance for hardly any hours contrasted with all day laborers who work for additional hours (Allah 1978, p. 156). The quantity of hours determined by the Ministry of L abor for all day business incorporates eight hours barring mid-day breaks; along these lines, hours worked not exactly the plot eight hours comprise low maintenance business. This permits both national and non-national staff to take up more than one occupation not at all like previously, whereby, individuals were just permitted to have each activity in turn. In any case, changes of the mind boggling subtleties of this grant are as yet in progress. This is on the grounds that different issues continue emerging with the experiencing of various achievements. Adolescent persons’ licenses spread youthful people between 15 to 18 years looking for work inside associations. Licenses for staff supported by their kinfolk spread dependants tried to work for an association. Which means ostracizes at long last have the chance to go about as their dependants supports. This permits their family to procure work licenses notwithstanding them not being qualified for any of the above recorded g rants (Allah 1978, p. 198). In this way, the presentation of various kinds of work grants made it simpler for the Dubai Bank Human Resource administrators to enlist staff in a simpler manner. For instance, they had the option to benefit from the licenses for staff supported by their family. This is on the grounds that; they utilized these licenses as motivating force while requesting the administrations of ostracizes. These licenses permit dependants of an ostracize to get business effectively on the grounds that getting a work grant stops to be an obstruction. In this manner, Dubai bank authorities keep on grasping the slow changes executed by the Ministry of Labor (Pawan 2007, p.77). With the ongoing worldwide downturn, infringement of work guidelines in the UAE expanded significantly. Subsequently, the Ministry of Labor thought of approaches which tried to address these infringement. Organizations like the Dubai bank, in this manner, straightened out their work connection approac hes to oblige the reconsidered guidelines from the Labor Ministry. The Ministry made three classifications of infringement known to people in general. Dark focuses granted by the Ministry demonstrated the earnestness of these infringement. The more the dark focuses earned by an association, the extreme the punishments forced. Punishments were either fines or the association would be minimized in extreme cases. The latter’s inconvenience happened when a firm obtained in excess of 100 dark focuses at whatever year (Pawan 2007, p.119).â

Word of the Week! Sojourn Richmond Writing

Word of the Week! Sojourn Richmond Writing Many of my readers will soon take a vacation or, if British, a holiday. Some will study abroad or go on sabbatical (a future Word of the week). All of these temporary absences count as a sojourn, a nice word for this time of year. Im currently finishing my sojourn to J.R.R. Tolkiens Middle Earth, one I have taken every decade since my early teens. Usage is really old for this word. The OED records several Fourteen Century examples, most with variant spellings. The etymology sketched out includes a few Romance languages but not any Latin term, though at Etymology Online theres an hypothesis that our word comes from the vulgar Latin  subdiurnare  to spend the day. All definitions refer to either a temporary stay somewhere, the place itself, or merely a digression. Thus for me, my year in Madrid was a sojourn before starting graduate school, yet Segovia nearby was itself a quiet sojourn from the hectic life of the Spanish metropolis. Graduates, what of your gap year before the grind of working life? You will never forget that sojourn. For the rest of you, as the humidity in Virginia rises in June and continues through August, where will your sojourn be? How long will you be away? And what do you bring back from that temporary change of scenery? Finally, can   you find a sojourn in the pages of a book or while watching a film? At present, my sojourn is with Frodo Baggins in Middle Earth, as real an imaginary place as any in fiction. Keep in mind that at the end of Lord of the Rings, Frodo makes not a sojourn but a permanent departure for the uttermost West, across the ocean. He will never return. But I hope you will! Please nominate a word or metaphor useful in academic writing by e-mailing me (jessid -at- richmond -dot- edu) or leaving a comment below.

You’ve just finished your weekly grocery shopping at your local big box store and you’re on your way out the door with a cart full of all the bargains you found and†¦show more content†¦Lowe said the company is always looking for new and innovative ways in which they could improve customer service. Redbox’s competitive advantage is the fact that they have surpassed companies in revenue as well as in their advantage in number of rental locations for customer availability. Most of all their competitive advantage is the fact that they have an alternative which other movie rentals do not; kiosks are placed in McDonald’s fast foods, grocery stores, and discount stores. Customers can purchase or rent online and pick up at any kiosk. They have a physical presence greater than 17,000 locations through their retail partners. Their locations continue to grow. One could wonder whether or not Redbox care for their employees after announcing in Downers Grove, Illinois the outsourcing of their Call Center to third parties in Texas and in Canada in February 2010. The closing will leave two hundred call center employees without jobs which are about 8% of the company’s workforce. There were questions raised as to whether or not it was a business strategy or declining economy. I believe there is some concern for public image but overall the concern is for Redbox to profit and like any other business their success is their priority. In 2009 there was a concern from three major studios, Century Fox, Warner Bros. and Universal, that DVD kiosks were going to kill sales and rentals.

Environmental Pollution Free Essays

Vi Lap Tran WRT 990 First Draft Environmental pollution Society is being civilized every time; technology is also being invented every day. Thus, human life’s quality has been developing. However, the increasing of environmental issues isn’t still solved, and one of the most important problems is the pollution. We will write a custom essay sample on Environmental Pollution or any similar topic only for you Order Now It’s defined, â€Å"Pollution is the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem i. e. physical systems or living organisms† (en. wikipedia. org). Many countries have a meeting annually to discuss how to decline and settle this problem. Many investigate of a lot scientists about the causes of the pollution are listed in statistics; the approaches are stated, but there is no specific solution to be united. There are three main causes of environmental pollution which are much mentioned; they are air pollution, soil contamination, and water pollution. Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution—some visible, some invisible—that contribute to global warming. Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered air pollution. Carbon dioxide, a greenhouse gas, is the crucial pollutant that is warming Earth. Though living things emit carbon dioxide when they breathe, carbon dioxide is widely considered to be a pollutant when associated with cars, planes, power plants, and other human activities that involve the burning of fossil fuels such as  gasoline and natural gas. Carbon dioxide also damages the ozone layer. Soil contamination frequently occurs in field, or the zone near nuclear plants. Soil contamination results when hazardous substances are spilled or buried directly in the soil. Chemical pesticides, which are always used in farming, cause serious consequence. Additionally, the radioactive leakage from the nuclear plants can also harmfully affect the broad ground. As a result, raising plants will be affected; they grow slowly and have little nutrition than the others. Beside that, contaminants in the soil can adversely impact the health of animals and humans when they ingest, inhale, or touch contaminated soil, or when they eat plants or animals that have themselves been affected by soil contamination. Water pollution can be defined â€Å"the addition of harmful chemicals to natural water† (dictionary. reference. com). There are four types of water pollution, such as: toxic substance, organic substance, thermal pollution, ecological pollution. Specifically, toxic substance, including herbicides, pesticides, and industrial compounds, is the most common matter. For instance, the situation at the Fukushima Daiichi nuclear power plant in Japan remains very serious, and according to the news from washingtonpost. com, â€Å"Leaked water sampled from one unit Sunday had 100,000 times the radioactivity of normal background levels. † Beside that, organic pollution, such as manure or sewage, is popular, too. At some developing countries, the sewage runs straight to the river without handling. The solutions were proposed in many conferences of environment. Such as using paper bags instead of nylons, declining the smog of the industrial plants, or using natural fuels replace for gasoline, and so forth. But there is no united agreement among the countries. Environmental pollution is a serious issue, and it must be settled as soon as well. Nowadays, many countries have realized the harm of pollution and begun spreading information about protecting environment to their citizen.

INTRODUCTION: The significance of environmental factors to the health and well-being of human populations’ is increasingly apparent (Rosenstock 2003; World Health Organization [WHO], 2010b). Environment pollution is a worldwide problem and its potential to influence the health of human populations is great (Fereidoun et al, 2007; Progressive Insurance, 2005. ). Pollution reaches its most serious proportions in the densely settled urban-industrial centers of the more developed countries (Kromm, 1973). In poor countries of the world more than 80% polluted water have been used for irrigation with only seventy to eighty percent food and living security in industrial urban and semi urban areas. Mara Cairncross, 1989). Industry, clustered in urban and semi-urban areas surrounded by densely populated, low-income localities, continues to pollute the environment with impunity (Government of Pakistan, 2009). Over the last three decades there has been increasing global concern over the public health impacts attributed to environmental pollution (Kimani, 2007), Human exposure to pollution is believed to be more intense now than at any other time in human existence (Schell et al, 20 06). Pollution can be made by human activity and by natural forces as well (Fereidoun et al, 2007; The Encyclopedia of the Atmospheric Environment, n. d). Selfish private enterprise and their lack of awareness of public well-being and social costs (Carter, 1985) and natural disasters (Huppart Sparks, 2006) e. g. volcanic ash from Iceland (World Health Organization [WHO], 2010a) are the one of the main reason of pollution. British Airways (1993) expresses their concern about environment in their general goal ‘to be a good neighbor, concerned for the community and the environment. This implies that, businesses now adopted this responsibility as part of their overall business strategy; which should match their broader business goals (Pearce, 1991). At present, the adoption of environmental auditing in any economic sector is voluntary but future legislation could well make it mandatory. (Goodall, 1995). Sharp Bromley (1979) posit that pollution control program evolves as a nationwide fixed cost-sharing effort relying upon voluntary participation. Interestingly, Goodall (1995) refers tourism as the potential to damage the environment. There is no doubt that excessive levels of pollution are causing a lot of damage to human animal health, plants trees including tropical rainforests, as well as the wider environment. (Tropical Rainforest Animals, 2008). According to Fereidoun et at (2007), Tehran is one of victim cities in terms of environmental pollution. Gautam et al (2009) nominated Indian cities, among the most polluted cities in the world. Carter (1985) found pollution in formally known Czechoslovakia (now Czech Republic and Slovakia) a serious issue which ultimately affects soils and vegetation. As Debarteleven (1992) postulates that environmental pollution and degradation are serious problems in Eastern and Central Europe. Kan (2009) originated the fact about China that, it has environmental problems, including outdoor and indoor air pollution, water shortages and pollution, desertification, and soil pollution, have become more pronounced and are subjecting Chinese residents to significant health risks. Environmental pollution is tangled with the unsustainable anthropogenic activities, resulting in substantial public health problems. (Khan, 2004). McGeehin et al, (2004) reported that U. S. population from infectious diseases to diseases such as cancer, birth defects, and asthma, many of which may be associated with environmental exposures. There is virtually no check on some 8,000 industrial units in USA that are contributing to high rates of pollution (Kaufman, 1993). Environmental health problems are not simply a conglomerate of concerns about Radiological health, water and wastewater treatment, air pollution control, solid waste disposal, occupational health, etc (Lynn Metzler, 1968). The Linton (1967), Spilhaus (1966) and Tukey (1965) made attempt to detail many of the specific environmental health problems which confront contemporary man.

Unfortunately polluted air is common throughout the world (EPHA, 2009) specially in developed countries from 1960s. (Kan, 2009). South of Poland (Krzeslak Korytkowski, 1994), Ukraine (Avdeev Korchagin, 1994), China (Kan, 2009), and Pakistan (Government of Pakistan, 2009; Khan, 2010) even famous crowded cities and countries are facing air pollution. Polluted air contains one, or more, hazardous substance, pollutant, or contaminant that creates a hazard to general health (Health and Energy, 2007). The main pollutants found in the air we breathe include, particulate matter, PAHs, lead, ground-level ozone, heavy metals, sulphur dioxide, benzene, carbon monoxide and nitrogen dioxide (European Public Health Alliance, 2009). Air pollution in cities causes a shorter lifespan for city dwellers (Progressive Insurance, 2005). Holland et al, (1979) illustrated that British scientists concluded that particulate and related air pollution at high levels pose hazards to human health. According to Mishra (2003) rapid growth in urban population, increasing industrialization, and rising demands for energy and motor vehicles are the worsening air pollution levels. He added other factors, such as poor environmental regulation, less efficient technology of production, congested roads, and age and poor maintenance of vehicles, also add to the problem. He further added that air pollution is caused of ill health and death by natural and man-made sources, major man-made sources of ambient air pollution include tobacco smoke, combustion of solid fuels for cooking, heating, home cleaning agents, insecticides industries, automobiles, power generation, poor environmental regulation, less efficient technology of production, congested roads, and age and poor maintenance of vehicles. The natural sources include incinerators and waste disposals, forest and agricultural fires (European Public Health Alliance, 2009). 1. Water pollution The water we drink are essential ingredients for our wellbeing and a healthy life. Unfortunately polluted water and air are common throughout the world (European Public Health Alliance, 2009). The WHO states that one sixth of the world’s population, approximately 1. 1 billion people do not have access to safe water and 2. 4 billion lack basic sanitation (European Public Health Alliance, 2009). Polluted wa ter consists of Industrial discharged effluents, sewage water, rain water pollution (Ashraf et al, 2010) and polluted by agriculture or households cause damage to human health or the environment. European Public Health Alliance, 2009). This water pollution affects the health and quality of soils and vegetation (Carter, 1985). Some water pollution effects are recognized immediately, whereas others don’t show up for months or years (Ashraf et al, 2010). Estimation indicates that more than fifty countries of the world with an area of twenty million hectares area are treated with polluted or partially treated polluted water (Hussain et al, 2001) including parts of all continents Avdeev Korchagin, 1994; Carter, 1985; Kan, 2009; Khan, 2010; Krzeslak Korytkowski, 1994; Wu et al, 1999) and this poor quality water causes health hazard and death of human being, aquatic life and also disturbs the production of different crops (Ashraf et al, 2010; Scipeeps, 2009). In fact, the effects of water pollution are said to be the leading cause of death for humans across the globe, moreover, water pollution affects our oceans, lakes, rivers, and drinking water, making it a widespread and global concern (Scipeeps, 2009). A drinking water contained a fluoride content ranging from 5. 26 to 26. 32 milligrams per liter and this is too high as compared to the World Health Organization’s standard of 0. 6 to 1. 7 milligram per liter (Rizvi, 2000). According to Ashraf et al (2010), In present scenario due to industrialization and increased population, the drains of Pakistan carry the industrial and municipal effluents that are ultimately carried that polluted water to the canals and rivers. The untreated International Refereed Research Journal  ¦ www. researchersworld. com  ¦ Vol. – II, Issue –2,April 2011 278 -Journal of Arts, Science Commerce  ¦ E-ISSN 2229-4686  ¦ ISSN 2231-4172 industrial and municipal wastes have created multiple environmental hazards for mankind, irrigation, drinking and sustenance of aquatic life. The drainage water contains heavy metals in addition to biological contaminations. This water pollution infected our food in addition to groundwater contamination when used to irrigate crops. Pakistani cities are facing tribulations of urban congestion, deteriorating air and water quality and waste management while the rural areas are witnessing rapid deforestation, biodiversity and habitat loss, crop failure, desertification, land degradation, clean drinking water, noise pollution, sanitation (Government of Pakistan, 2009). 1. 3 Land/ Solid waste Pollution Improper management of solid waste is one of the main causes of environmental pollution (Kimani, 2007). Land pollution is one of the major forms of environmental catastrophe our world is facing today (Khan, 2004). As Bulgaria and the Slovak Republic, heavy metal industries have produced wastes that are deposited into landfills without special precautions (Lenkova Vargova, 1994; Spassov, 1994). Cucu et al (1994) posit that approximately half of the population lives in the vicinity of waste sites that do not conform to contemporary standards in Romania. Czech Republic’s coal and uranium mines have produced serious pollution problems, and much of the solid industrial waste containing heavy metals is disposed of, without pretreatment, in open dumps (Rushbrook, 1994). Harvath Hegedus (1994) concluded as the worst pollution of Hungary comes from open cast mines, lignite-based power plants, chemical factories, and the aluminum industry. The Silesia district in the south of Poland has severe contamination from mining and industry (Krzeslak Korytkowski, 1994). Avdeev Korchagin (1994) conceived soil pollution are critical issues in Ukraine. World Bank (2002) found Particulate matter is the most serious pollutant in large cities in South Asia. 2. Effects of Dying Environment on Human, Animals and Plants Environment dying is global perilous point which catastrophically the human, animals and plants. Air pollution results are Cancer (Ries et al. 1999; European Public Health Alliance, 2009), neurobehavioral disorders (Blaxill 2004; Landrigan et al. 2002; Mendola et al. 2002; Schettler 2002; Stein et al. 2002), cardiovascular problems (European Public Health Alliance, 2009; Tillett, 2009), reduced energy levels (Colls, 2002), premature death (European Public Health Alliance, 2009), asthma (Brauer et al, 2007; Gehring et al, 2002; Jacquemin et al, 2009; Mannino et al. 998; McConnell et al, 2006; Modig et al, 2006), asthma exacerbations (D’Amato et al, 2005; Heinrich Wichmann, 2004; Kunzli et al, 2000; Nel, 2005;), headaches and dizziness (Colls, 2002), irritation of eyes, nose, mouth and throat (Colls, 2002), reduced lung functioning (Colls, 2002; Gauderman et al, 2005), respiratory symptoms (Colls, 2002; Vichit-Vadakan, 2 001), respiratory disease (European Public Health Alliance, 2009; Firkat, 1931), disruption of endocrine (Colls, 2002; Crisp et al, 1998) and reproductive and immune systems (Colls, 2002; European Public Health Alliance, 2009). London Fog episode of 1952, where a sharp increase in particulate matter air pollution led to increased mortality among infants and older adults (Woodruff et al, 2006). High air pollution levels have been linked to infant mortality. (Fereidoun et al, 2007). Air pollutants can also indirectly affect human health through acid rain, by polluting drinking water and entering the food chain, and through global warming and associated climate change and sea level rise. Mishra, 2003). Associations between particulate air pollution and respiratory disease are reported in Meuse Valley, Belgium, in December 1930 (Firkat, 1931), an episode in Donora, Pennsylvania, in 1948 (Ciocco Thompson, 1961) and International Refereed Research Journal  ¦ www. researchersworld. com  ¦ Vol. – II, Issue –2,April 2011 279 -Journal of Arts, Science Commerce  ¦ E-ISSN 2229-4686  ¦ ISSN 2231-4172 the most notable occurring in December 1952 (Logan, 1953). According to Gardiner (2006) acid rain destroys fish life in lakes and streams and kill trees, destroy the leaves of plants, can permeate soil by making it inappropriate for reasons of nutrition and habitation, unwarranted ultraviolet radiation through the ozone layer eroded by some air pollutants, may cause skin cancer in wildlife and damage to trees and plants, and Ozone in the lower atmosphere may damage lung tissues of animals and can prevent plant respiration by blocking stomata (openings in leaves) and negatively affecting plants’ photosynthesis rates which will stunt plant growth; ozone can also decay plant cells directly by entering stomata. Polluted drinking water or water polluted by chemicals produced waterborne diseases like, Giardiasis, Amoebiasis, Hookworm, Ascariasis, Typhoid, Liver and kidney damage, Alzheimer’s disease, non-Hodgkin’s Lymphoma, multiple Sclerosis, Hormonal problems that can disorder development and reproductive processes, Cancer, heart disease, damage to the nervous system, different type of damages on babies in womb, Parkinson’s disease, Damage to the DNA and even death, meanwhile, polluted beach water contaminated people like stomach aches, encephalitis, Hepatitis, diarrhoea, vomiting, gastroenteritis, respiratory infections, ear ache, pink eye and rashes (Water Pollution Effects, 2006). Loss of wild life is directly related to pollution (Progressive Insurance, 2005) and according to Water Pollution Effects (2006) on animals i) Nutrient polluted water causes overgrowth of toxic algae eaten by other aquatic animals, and may cause death; it can also cause eruptions of fish diseases, ii) Chemical contamination can cause declines in frog biodiversity and tadpole mass iii) Oil pollution can increase susceptibility to disease and affect reproductive processes and negatively affect development of marine organisms and it can also a source of gastrointestinal irritation, damage to the nervous system, liver and kidney damage iv) Mercury in water can cause reduced reproduction, slower growth and development, abnormal behavior and death v) Persistent organic pollutants may cause declines, deformities and death of fish life and Fish from polluted water and vegetable/ crops produced or washed from polluted water could also make impact on human and animal health. More sodium chloride (ordinary salt) in water may kill animals and plants, plants may be killed by mud from construction sites as well as bits of wood and leaves, clay and other similar materials and plants may be killed by herbicides in water (Kopaska-Merkel, 2000). For tree and plants water pollution may disrupt photosynthesis in aquatic plants and thus affecting ecosystems that depend on these plants (Forestry Nepal, n. d). Soil pollution effects causes according to tutorvista (n. d) are cancer including leukaemia and it is danger for young children as it can cause developmental damage to the brain furthermore it illustrated that mercury in soil increases the risk of neuromuscular blockage, causes headaches, kidney failure, depression of the central nervous system, , eye irritation and skin rash, nausea and fatigue. Soil pollution closely associated to air and water pollution, so its numerous effects come out as similar as caused by water and air contamination. TNAU Agritech Portal (n. d) soil pollution can alter metabolism of plants’ metabolism and reduce crop yields and same process with microorganisms and arthropods in a given soil environment; this may obliterate some layers of the key food chain, and thus have a negative effect on predator animal class. Small life forms may consume harmful chemicals which may then be passed up the food chain to larger animals; this may lead to increased mortality rates and even animal extinction. 3. CONCLUSION: It appears that polluted environment is global an issue and world community would bear worst results more as they already faced. As effective response to pollution is largely based on human appraisal of the problem (Kromm, 1973) and pollution control program evolves as a nationwide fixed cost-sharing effort relying upon voluntary participation (Sharp Bromley, 1979). Education, research, and advocacy, are lacking in the region as preventive strategy for pollution International Refereed Research Journal  ¦ www. researchersworld. com  ¦ Vol. – II, Issue –2,April 2011 280 -Journal of Arts, Science Commerce  ¦ E-ISSN 2229-4686  ¦ ISSN 2231-4172 (Fitzgerald, 1998) especially in Asia. At present the adoption of environmental auditing in any economic sector is voluntary but future legislation could well make it mandatory (Goodall, 1995) and still time available to use technology and information for environmental health decision. Policymakers in developing countries need to design programs, set standards, and take action to mitigate adverse health effects of air pollution. Healthy people mean human resources are the main object of any successful business or country. These societal beneficial efforts need to carefully adapt available knowledge from other settings, keeping in mind the differences in pollutant mixtures, concentration levels, exposure patterns, and various underlying population characteristics.

Photoperiodism Essays (243 words) - Circadian Rhythm, Botany

Photoperiodism annon Plants and animals in the temperate zones respond in different ways to the amount of daylight in 24-hour periods. This response to day length is called photo periodism. It controls many activities, among them is the flowering of plants. The ability to respond to day length is linked to an inner, light-sensitive circadian rhythm. In the temperate zones, day lengths during the natural 24-hour cycle vary with the seasons. In winter and spring, the period of light lengthens; in summer and autumn, it shortens. Plants in these zones undergo alternate 12-hour phases of light sensitivity. During one 12-hour phase, decreasing exposure to light induces a short-day reaction. For example, deciduous trees under the influence of the shorter days of fall drop their leaves. During the other 12-hour phase, more exposure to light creates a long-day reaction. Deciduous trees grow leaves again during the lengthening days of spring. This indicates that through their sensitivity to changes in the duration of light, plants can measure day length to determine the season and the time spans within a season. Florists can often manipulate greenhouse plants into producing blossoms out of season by exposing them to periods of artificial light. Some scientists are not certain that the biological clock of any organism is completely endogenous. They think that even under the most constant of laboratory conditions living things are aware of the Earth's rotation and that this has an effect on the wheelof their clocks. However, many scientists believe that such factors are not essential to the functioning of biological clocks.
