Problem Statement Scope And Limitation Engineering Essay In this research ZnO thin film will be doped with aluminium using sol-gel spin-coating method. Then the Al-doped ZnO thin film (as seed catalyst) on a glass substrate will be then layered bottom of an aligned ZnO nanorod structure which was prepared using sonicated sol-gel immersion technique. The nanorod thin film parameters will be characterizing through its I-V curve characteristics and also the optical and absorbance of aligned ZnO nanorod thin film. INTRODUCTION 1.2.1 Background study UV sensor or stands for ultraviolet sensor are important devices that can be used in commercial and military applications. The applications are including gas sensing, space research, high temperature flame detection, air quality monitoring and many more. UV detectors currently used silicon-based detectors and photomultiplier tubes. These materials require costly filters and attenuators. However by replacing those technologies with wide band-gap semiconductors such as zinc oxide (ZnO) have been suggested [1]. UV light emitting or receiving devices, solar cells, gas sensor and transparent electrodes are some of the zinc oxide applications. Various deposition methods such as chemical vapor deposition, sputtering and molecular beam epitaxy were used to fabricate ZnO thin films. However, these deposition methods are high production cost because required high temperature processing and vacuum technology [2]. In this paper, the purpose of this research is to fabricate ultraviolet sensor using zinc oxide thin film and characterize the sensor performances by its electrical properties. Furthermore, this research is to characterize aluminum doping concentration and the nanostructure of zinc oxide thin film. In this research, sol-gel spin coating method was used to prepare Al doped zinc oxide thin film and an aligned ZnO nanorod structured thin films on a glass substrate by the sonicated sol-gel immersion method. 1.2.2 Literature Review ZnO is an n-type semiconductor with a direct band gap of 3.42eV and because of the oxygen vacancies and intrinsic defects such as interstitial zinc atoms, the electrical conductivity of the films is large [3]. It is very good material for electronic device application due to its wide band gap and large exciton binding energy of 60meV [4]. The properties of ZnO thin film can be improve by a doping process and annealing process [3]. There are that focus on the doping process. To improved electrical or optical properties of ZnO, ZnO were frequently doped with group 3, 4 and 5 elements such as Gallium (Ga), Sn and Aluminium (Al) [5]. Al doping is most suitable because its cheap, abundant and non-toxic material and will produce Al doped ZnO thin film with higher optical transmittance and low resistivity in infrared region [4]. From the journal [6], radio-frequency (RF) reactive magnetron sputtering method was used to deposit Al-doped ZnO on the smooth nucleation side of FSD films by. The electrical properties were discussed. The first electron concentration increased and next decreased with the increase of Al doping concentration. The maximum carrier concentration achieve when the film is doped with 2at% Al. Hall mobility is inversely proportional to the Al doping concentration. The high temperature annealing process is use to enhance the Hall mobility of the films [6]. From the journal [7], ZnO thin films with various weight percentages of aluminium and the electrical properties were discussed using sol-gel dip-coating method. The conductivity shows higher response of the doped ZnO thin films under UV compared with dark condition. Both condition proof that the conductivity of ZnO is directly proportional to doping concentration. The optical band gap energy is also directly proportional with doping concentration. The transmittance of ZnO thin films is about 75% when wavelength from 390nm to 850nm. From the journal [8], at different dopant concentration the electrical properties of Al-doped ZnO thin films were discussed using sol-gel method. The resistance first decrease with increase aluminium ion concentration. Then the resistance of doped thin films increased with increasing dopant concentration and it decreases at higher Al concentration. The transmittance of ZnO thin films is about 80% when wavelength from 370nm to 850nm. The advantage of gallium is an excellent dopant for increasing the conductivity and this source is less reactive and more resistive oxidation. Based on the journal [5], Ga-doped ZnO nanowires were growth using thermal deposition method. The ZnO nanowires have grown uniformly with high yield and average length of each nanowire is about 1.3um. From the XRD pattern, it can be deduced that the Ga element doped into the nanowires creates a clear broadening. The Ga-doped ZnO nanowires have a greater field-enhancement factor than the undoped ZnO nanowires [5]. Aqueous solution process with post-growth rapid photothermal processing (RPP) was used to prepare Sn-doped ZnO nanorods to develop aligned Sn-doped ZnO nanostructure. Aqueous solution method was chosen in preparation of metal oxide nanoparticles structure due to its cost and environment friendly. Rapid photothermal processing (RPP) as an alternatives of thermal annealing was combine with aqueous solution due to short cycle time, reduced exposure and flexibility [9]. Based on journals [6], [7] and [8], the optimum doping concentration of aluminium is 2at%, 5at% and 1.5at% respectively. Optimal aluminium doping concentration will gives highly semiconducting properties of Al-doped ZnO thin film for application UV sensor [4]. A research had done on various Al doping concentration and the optimum doping concentration is at 1at% Al. This research will used 1at% Al concentration based on journal [4]. Aligned ZnO nanorods that were prepared using sonication method are a simple way and very low cost method compared to other techniques. It also will growth high quality ZnO nanorod with a small diameter size [10]. 1.2.3 Problem Statement, Scope and Limitation Most people are aware of the effects of UV through the painful condition of sunburn, but the UV spectrum has many other effects whether its benefits or damaging to human health. Too much exposure to UV radiation can affect human health. UV application for optical sensor used 230 nm to 400nm wavelength which is ultraviolet B (UVB) which is harmful to human skin. Since it is harmful to human skin, metal oxide semiconductor films have been considered due to its excellent chemical and physical properties. One of them is zinc oxide material. Zinc oxide is not only good in optoelectronic but also in electrical properties. Zinc oxide is then will be doped with aluminium to enhanced the zinc oxide thin film properties by using sol-gel spin-coating method. It is important to choose the right method for preparing aligned ZnO nanorod. The scope of this research is to investigate the electrical properties (I-V characteristic) and the optical properties of the ZnO nanorod thin film at different i mmersion time. The limitations of this research are on the solution preparation and deposition condition which are different for different groups and on the fix parameter. 1.2.4 Significant of the research The nanomaterials based sensors are raising the advantage of size reduction and enhanced functionality [12]. This research will used a simple method to prepare an aligned ZnO nanorod thin film which is sol-gel immersion method which is this method has not been reported by any research group. Moreover it is very low-cost method. 1.2.5 Objectives To prepare Al-doped ZnO thin film as seed catalyst layer. To prepare aligned ZnO nanorod thin film at different immersion time. To fabricate aligned ZnO nanorod thin film based UV photoconductive sensor. To characterize fabricated UV sensor. 1.2.6 Research Questions To achieve the objective of this research, some research questions would need to focus on which are: What is the I-V curve characteristic of aligned ZnO nanorod thin films before and after exposing to the UV illumination? What is the optical and absorbance characteristic of aligned ZnO nanorod thin films? How to fabricate ZnO thin film? What is the factor affecting the nanostructure ZnO thin film before and after exposing to the UV illumination? CHAPTER 2 2.1 Research Methodology 2.1.1 Al doped ZnO thin films Sol-gel spin-coating method was used to prepare Al doped ZnO thin films. The solution include zinc acetate dihydrate (Zn(CH3COO)2 2H2O) as precursor, aluminium nitrate nonahydrate (Al(NO3)3 9H2O) as a dopant source,monoethanolamine (MEA, C2H7N14) as a stabilizer and 2-methoxyethanol as a solvent were prepared. The concentration of aluminium nitrate was 1.0at% Al doping and the molar ratio of MEA to zinc acetate was fixed at 1.0. At 3 hours before aged at room temperature for 24hours to yield clear and homogeneous solutions the solution was stirred at 80Â °C. The solutions were then used for deposition process by spin-coating technique. Substrates used were microscope on the glass substrates. At room temperature, the spin-coating was performed using 10 drops of solution per deposition with a speed of 3000rpm for 60s. The films were preheated in atmosphere ambient at 150Â °C for 10 minutes to evaporate the solvent each time after deposition process. The films were annealed at 500Â ° C for 1 hour in air ambient using a furnace (Protherm) after repeating the coating procedure 10 times. The crystal structure and orientation of ZnO thin films were investigated by X-ray diffractometer (XRD). The cross-section of the film thickness is observed by using scanning electron microscope (SEM). By using UV-vis-NIR spectrophotometer, the optical properties of ZnO thin films were measured in the wavelength range from 200 nm to 1500nm. The electrical properties were measured by dc probing system [4].

The sol-gel coating method was used to prepare the Al-doped ZnO thin film as a seeded catalyst that was prepared on the glass substrate. A solution was prepared of 0.1M zinc nitrate hexahydrate (Zn (NO3)2 .6H2O) and 0.1M hexamethylenetetramine (HMT, H2NCH2CH2OH) in deionized water (DI). At 50Â °C for 30 minutes using an ultrasonic water bath, this solution was sonicated. The solution was then aged and stirred for 3 hours at room temperature. The sonicated and aged solution was poured into a Schott bottle, at the bottom which had been placed the horizontal Al-doped ZnO thin film coated glass substrate. The capped bottle was then immersed in a 95Â °C water bath for 4 hours. After the immersion process, the sample was cleaned with DI water and allowed to dry in ambient air. By using field emission scanning electro n microscope (FESEM) and X-ray diffraction (XRD), the resulting ZnO nanorod structure was characterized for surface morphology and crystallinity.

Optimum aluminium doping concentration will gives highly semiconducting properties of Al-doped ZnO thin film for application UV sensor. It is important to find low cost method. The ZnO nanorods have an average diameter of 100nm. An average optical transmittance of 78% was observed. The electrical properties and optical properties of an aligned ZnO nanorod thin film were affected when varying the immersion time. High degree of crystalline, large surface area availability, a visible wavelength transparency and high UV absorption properties, this method show its suitable for UV sensor application.

Patient-Focused Pharmacy Arguments

Patient-Focused Pharmacy Arguments Catalysts For Change: Will Pharmacy in the United States Embrace Them? David A. Latif, M.B.A., Ph.D. OBJECTIVES: To briefly discuss previous paradigm change calls for pharmacy practice to move toward a more patient-focused profession, and to make the case that several catalysts are in place to move toward a more patient-focused profession in the near future. SUMMARY: From Eugene White’s â€Å"Office Based† practice model to Helpler and Strand’s â€Å"Pharmaceutical Care† model, during the past 50 years there have been no shortage of expert advocates for the pharmacy profession moving toward a patient-focused one. The results so far have not been as optimal as many would have hoped. An argument is made that the confluence of the passage of the Affordable Care Act, pharmacist manpower stability (and fear by many of an impending oversupply), and the imminent and future impact of automation and technology serve as excellent catalysts to influence the profession to move much more rapidly toward the patient-focused care paradigm. CONCLUSION: The profession must embrace the opportunities discussed regarding moving quickly toward the patient-focused paradigm. Although several barriers still exist, especially in the community setting, it is difficult to see a path whereby pharmacy can rely on dispensing for its livelihood to the extent it has historically. Therefore, the profession has little choice but to embrace the role of the pharmacotherapy expert in collaborative health care practice. During the past half century several authors have called for a paradigm change in the pharmacy profession away from a drug product focus to a more patient and clinically focus.1-7 From Eugene White’s concept of an â€Å"office-based pharmacy† practice in the early 1960s (in violation to the profession’s 1952 Code of Ethics) to Donald Brodie’s thoughtful â€Å"Drug-Use Control† in the 1969 to Hepler and Strand’s â€Å"Pharmaceutical Care,† in the late 1980s there has been no shortage of expert advocates espousing the need for pharmacists to reduce their reliance on the distributive function of prescription medications and emphasize the cognitive component.2,5,6 The need for the paradigm shift revolved around several themes, including the following: 1. To reduce preventable drug-related morbidity and mortality; 2. To regain the professionalization of pharmacy that was ameliorated due to the rise of prepackaged and premixed drugs after Wo rld War II; and 3. To protect against future loss due to automation.1-7 Despite this, especially in the community setting, there is wide-spread agreement that patient-focused care is not practiced as optimally and consistently as it could be practiced.8,9 In addition, historically there have been many barriers to patient-focused care, including time constraints at the community level.10 Perhaps the most significant barrier is the fact that pharmacies have not been reimbursed at a profitable level for providing patient care services. 10,11 One major reason for the underwhelming changes relates to the fact that, with significant shortages of pharmacists during the recent past resulting in meaningful salary increases, there was not a sense of urgency to consistently and fundamentally change pharmacy practice. The situation may be different today due to at least two major factors. First, according to the Aggregate Demand Index (ADI) most of the United States is â€Å"in balance† with a minority of states in moderate demand.12 This contrasts to a high demand for pharmacists as recently as 2007.12 Contributing factors to this supply change include an unprecedented growth in both new schools and colleges of pharmacy, as well as significant expansion of current programs.13,14 Also, some will argue that many pharmacists are working longer than they expected due in part to the Great Recession of 2008. A second reason for why the situation may be different today has to do with the advances in automation and technology. Although there have been previous discussions regarding automation and technology and their impact on the profession, there is some evidence to suggest that the distributive function of pharmacy (i.e., dispensing) will be negatively impacted in the near and long term. A recent summary by Colvin regarding the advances made in technology spotlights the impact these advances may have on the world of work. 15 According to Colvin, the key question to ask is: â€Å"What can people do better than computers?† For example, what impact will Google’s autonomous car have on the future of trucking? What is happening to lawyers is a useful example of how technology can impact professional jobs. In the discovery phase of litigation, computers are much better than people for screening documents for relevance related to germane law cases. They are also better at predicting Supreme Court decisions than humans. That does not bode well for high salaries and full employment in the law profession. Watson, IBM’s cognitive computing system, is not only smarter than we are, but has become 240% faster in the past 2 years! In pharmacy, the robot at University of California at San Francisco’s hospital has replaced all dispensing and has not had an error in 350,000 prescriptions.16 Although the hospital has not reduced its pharmacist staff it is possible that they could in the future. In addition, the technology can be used in other pharmacy organizations to potentially reduce the need for pharmacis ts. On a macro-economic level, economists struggle to explain why the 2008 economic recovery was so tepid. In past recessions, it has taken only 18 months for the U.S. economy to return to pre-recession levels. It has taken 77 months for the 2008 recession. Could advancing technology be a factor in why real wages have stagnated? Former Treasury secretary and economist Larry Summers recently stated: 17 Until a few years ago I didn’t think this was a very complicated subject; the Luddites were wrong, and the believers in technology and technological progress were right. I’m not so completely certain now. We now have the lowest work participation in decades for those in the 25 to 54 age range. Why? What is the answer in pharmacy to the question â€Å"What jobs can humans do better than computers?† Certainly, pharmacists cannot dispense prescriptions better than computers. But pharmacists can perform the non-routine task of patient-focused care better than computers (although some believe that future automation will include robots that can show empathy and emotion). Quality investigations such as the Ashville Project have demonstrated that pharmacists can reduce health care costs and improve patients’ medication therapy outcomes.18 Despite these successes, due to a myriad of reasons such as lack of consistent reimbursement for pharmacist services, many pharmacists’ clinical skills remain underutilized. Interestingly, former APhA President Bruce R. Canaday’s gave a thought provoking inaugural address on March 21, 2006 when he stated the dilemma facing the pharmacy profession.19 He stated that pharmacy needs to change its model of practice â€Å"Becaus e if we don’t, we could become extinct, with our roles in the health care system replaced or eliminated.†19 He cogently argued that optimal medication order fulfillment can be done from anywhere in the world; therefore not changing may result in the pharmacist’s job being marginalized. Since 2006, automation and technology have become more advanced. Paradigm changes often are precipitated by catalysts for change. The catalysts today present tremendous opportunities for pharmacists to utilize their previous underutilized skills in optimizing patients’ complex medication management therapy. In addition to the threat on pharmacists’ jobs from remote medication order fulfillment serving as a catalyst to change, provisions stemming from the Affordable Care Act (ACA) that includes Accountable Care Organizations (ACO) and Patient Centered Medical Homes (PCMH) may serve as meaningful catalysts.20,21 These provisions have the goal of reducing costs while imp roving quality. Because of ACA, millions of more citizens and residents of the United States have health insurance. Subsequently, the aforementioned opportunities exist for many health professions, including pharmacists, to optimize patients’ health outcomes. To realize these opportunities, a necessary first step is to be recognized as a Health Care Provider under Social Security. Then, the profession must find a consistent way to get paid for their services in a consistent manner. Because of the Pay-For-Performance incentive programs inherent in ACA the environment is amenable to the cost-saving pharmacist services that pharmacists can excel at. White and Latif presented a model that could work where the pharmacist (with residency training) works as the pharmacotherapy expert in physicians’ offices throughout the United States.22-24 These highly skilled pharmacists would initiate and monitor patients’ complex medication management outcomes. About a third of pri mary care physicians’ time is spent with chronic medication patients.25 By combining the physician’s expertise (diagnosis) with the pharmacists expertise (optimal pharmacotherapy outcomes) the synergy gained may optimize patient outcomes and reduce health care costs due to drug misadventures. White and Latif discussed the changes needed for such a model to work.22-24 The United States spends approximately 50% more on health care than the next most expensive country, Norway.26 If health care were a country, it would be tied with France for the 5th largest economy. The rate of increase of health care expenditures is unsustainable. At its current pace, 50% of our GDP could go to health care by 2070! Therefore, there will be intense pressure on the industry to reduce its costs. In addition to nurse practitioners and physician assistants, pharmacists can play a crucial role in reducing health care costs. Despite the aforementioned positives for pharmacy three key issues remain to be seen: 1. Will pharmacy be awarded Provider status in the near term?; 2. If and when they are awarded Provider status, will they be able to consistently procure fair reimbursement for services that save the health care system money?; and 3. Assuming #s one and two come to fruition, will the United States need as many pharmacists as pharmacy schools are producing? It could b e that highly trained pharmacists will add significant value to the health care system, but because the dispensing function ameliorates fewer pharmacists are needed. In summary, healthcare and pharmacy has and will continue the change. Health care costs must be reduced in the coming decades or the United States economy will collapse (i.e., it is not possible to have 30 to 50% of GDP going to Health Care). The next 5 to 10 years will be critical for the pharmacy profession. Because it is difficult to see a path whereby pharmacy can rely on dispensing for its livelihood to the extent it has historically, pharmacy has little choice but to embrace the role of the pharmacotherapy expert in collaborative health care practice. As former APhA president Canady stated regarding the alternative: â€Å"Because if we don’t, we could become extinct, with our roles in the health care system replaced or eliminated.† 19 REFERENCES White EV.

Literature And The Workplace Essay -- Literature Work Labor

Literature and the Workplace The relationship between literature and the workplace environment is primarily one of human emotion and interaction. How a person feels about their work, or the issues faced within the workplace are fodder for fiction, non-fiction, and poetry alike. The majority of the working masses actually have a relatively small number of experiences. Though the work itself may be different, and the specific situations unique, the overall anxiety, fears, and concerns are generally the same. This means the audience for this type of literature is wide. Some of the common themes that are found in the literature of work might include finding one’s vocation and pride in work. These are two of the most positive experiences, and the focus of this paper. The works we will be discussing are the short story, â€Å"My Lack of Gumption,† the essay, â€Å"Pablo Picasso: Living in his own Shadow†, and the poem, â€Å"Old Men Working Concrete.† Each of these works speaks to the pride and passion of the characters doing the work. Literature is a form of expression that allows a greater range of feeling and emotion to be experienced than any other form. Theater must rely on body language and spoken dialect to form a picture and convey feeling. The written word allows insight into the mind, to see and feel what the individual is thinking at the time. Through this work, each person can relate the work to his or her own situation. In this way, literature is interpreted in many different ways depending on the experience and background of the reader. Workplace literature today... ...les; â€Å"Mary Poppins† may provide the inspiration to work with children, brining joy into their life. Young teens may find themselves drawn to Detective stories and pursuing a career in Law Enforcement. The majority of literature has some aspect of human psychology in it. If those humans are employed, there will be an element of work that the reader can relate to and perhaps apply to their own experiences. From technical guides to the literary brilliance of â€Å"Moby Dick†, literature shapes the lives of every reader. It has a place in every environment, be it the workplace or home. Pick up a book, settle under the blanket, and curl up with the mind of the writer – you are sure to find a piece of yourself there. Reference LaRocco, C., & Coughlin, J. (1995).

Why Rate? To paraphrase the old Chuck Berry tune, bye-bye, Johnnie. Johnnie Johnson, the rhythm-and-blues piano wizard whose pioneering partnership with Berry produced such indelible tracks as "Roll over Beethoven" and "No Particular Place To Go" and helped to lay the foundations for rock 'n' roll, died Wednesday. He was 80. According to his agent at New York-based Talent Consultants International, Johnson died of natural causes at his home in St. Louis. Musician John May told the St. Louis Post-Dispatch that Johnson had been hospitalized a month ago for pneumonia and had also been on dialysis for a kidney ailment. Despite his ailments, Johnson refused to stop playing, taking the stage as recently as two weeks ago Johnson, who was inducted into the Rock and Roll Hall of Fame in 2001, influenced generations of rockers through his collaborations with Berry--everyone from Elvis Presley and Little Richard to the Beatles and the Rolling Stones. Fellow rock originator Bo Diddley, who performed with Johnson on Feb. 9, called Johnson "a great man and a great musician." "It was so much fun to play with Johnnie," Diddley said in a statement. "He will be missed but his music will live on." Berry was traveling back from Europe and was not immediately available for comment, according to his publicist. A self-taught musician, bandleader and composer, Johnson composed the riffs for many of Berry's most famous tunes, including "Maybellene," "Sweet Little Sixteen" and "Rock and Roll Music," which Berry transposed to guitar. Berry wrote his best-known song, "Johnny B. Goode," in tribute to Johnson. But it was Johnson who actually gave Berry his first big break. On New Year's Eve in 1952, Johnson, then fronting the his own trio in St. Louis, was stuck. His sax player fell ill and he needed an emergency replacement, so he called in his pal Berry, a promising young guitarist, to fill in. The show was a hit, Johnson asked Berry to join the band, and soon the more charismatic Berry was the frontman. Their partnership produced dozens of hit songs before they parted company in 1973. Wracked by alcoholism, Johnson fell off the radar. He was driving a bus when Rolling Stones guitarist Keith Richards tracked Johnson down during the making of the 1987 Berry documentary, Hail! Hail! Rock 'n' Roll. Richards, convinced that Johnson should be in the rock pantheon alongside Berry, launched a high-profile campaign to get Johnson into the Rock and Roll Hall of Fame.

Lucid dreaming means dreaming while knowing that you are dreaming. The term was coined by Frederik van Eeden who used the word "lucid" in the sense of mental clarity. Lucidity usually begins in the midst of a dream when the dreamer realizes that the experience is not occurring in physical reality, but is a dream. Often this realization is triggered by the dreamer noticing some impossible or unlikely occurrence in the dream, such as flying or meeting the deceased. Sometimes people become lucid without noticing any particular clue in the dream; they just suddenly realize they are in a dream. A minority of lucid dreams (according to the research of LaBerge and colleagues, about 10 percent) are the result of returning to REM (dreaming) sleep directly from an awakening with unbroken reflective consciousness. The basic definition of lucid dreaming requires nothing more than becoming aware that you are dreaming. However, the quality of lucidity can vary greatly. When lucidity is at a high level, you are aware that everything experienced in the dream is occurring in your mind, that there is no real danger, and that you are asleep in bed and will awaken shortly. With low-level lucidity you may be aware to a certain extent that you are dreaming, perhaps enough to fly or alter what you are doing, but not enough to realize that the people are dream representations, or that you can suffer no physical damage, or that you are actually in bed. 1.2 IS LUCID DREAMING THE SAME AS DREAM CONTROL? Lucidity is not synonymous with dream control. It is possible to be lucid and have little control over dream content, and conversely, to have a great deal of control without being explicitly aware that you are dreaming. However, becoming lucid in a dream is likely to increase the extent to which you can deliberately influence the course of events. Once lucid, dreamers usually choose to do something permitted only by the extraordinary freedom of the dream state, such as flying. You always have the choice of how much control you want to exert. For example, you could continue with whatever you were doing when you became lucid, with the added knowledge that you are dreaming. Or you could try to change everything--the dream scene, yourself, other dream characters.

Ending Poverty in the Third World Essay

Poverty continues to be a large part of the third world countries, affecting many people’s wellbeing and country stability in the new millennium, despite many strategies put in place to alleviate the poor status. Due to the continued prominent place of poverty in the third world countries, significant strategies are coming up comprising of political, social, spiritual, environmental, and managerial coping strategies. The strategies have realized various levels of success although it highly depends on the place of implementation and the taskforce mandated to implement the development strategies. The failure or minimal success of some of the strategies geared towards ending poverty in the third world, has encouraged the developed and developing countries, and developmental related agencies to focus on coming up with new theories with the likelihood of more success. Nevertheless, poverty in the third world continues to be a major challenge in the world with many strategies, some successful and others marked with dismal failure coming up to alleviate third world poverty. Description of Poverty in the Third World Poverty implies a lack of adequate food and shelter, lack of better housing, sanitation, access of safe drinking water attributed to lack of income to facilitate acquisition of basic necessities, a sense of powerlessness, and vulnerability to adverse shocks (Parsed et al, 2005, p. 290). The concept of poverty encompasses a large spectrum of attributes such as levels of income and consumption, health, education, security, and housing. Nevertheless, poverty is largely an attribute of low income that prevents individuals and families from acquiring and enjoying basic life necessities such as nutritious food, clothing, shelter, and clean water. Regions highly affected by the incidence of poverty are Africa and Asia, also referred as the third world, the developing nations, or less developed countries, although Africa suffers a more rampant extent of poverty compared to Asia (Parsed et al, 2005, p. 290). Among these countries, the poor live mostly on less than a dollar a day, although some live on $2 a day, although the incidence and gap may not be significant either in the African or Asian developing countries. In the past decade, the development of the concept of globalization gave promise to the reduction of poverty in the third world because of the removal of control on free movement of goods and services; however, the initial hope is yet to be realized. Encouraging the possibility of poverty eradication within the emergence of globalization has been the United Nations and the development of goals towards alleviation of poverty, and the entry of the international community in the process of poverty eradication in the third world. Poverty and the Millennium Development Goals At the turn of the millennium in 2000, the United States member states agreed on eight international development goals to be achieved by 2015 that the countries adopted in 2001 in order to assist impoverished nations and create a sustainable global community. The first goal of the eight was to eradicate extreme poverty and hunger, with the target being to half the number of people living on less than a dollar per day and reduce by half the number of people suffering from hunger. From the creation of the Millennium Development Goals (MDGs), the United Nations Development Programme (UNDP), Non-Governmental Organizations (NGOs), and various public, private, and federal agencies worked towards establishing developmental strategies that would facilitate the realization of the goals (Eggen and Bezemer, 2007, p. 1). The strategies have been constructed mainly along the international community through the UNDP, NGOs funded by international groups, the World Bank, and the International Monetary Fund (IMF) towards poverty reduction. Agreeably, poverty reduction especially in the third world has been an ongoing process in many countries. However, its recognition by the UN made it a priority within the international community with the MDGs becoming a coherent expression of global development priorities and an instrument to shape development policies (Eggen and Bezemer, 2007, p. 2). The introduction of the MDGs meant that the world had a standard by which to measure the success of policy interventions in poverty reduction within a certain period. In the discussion of the strategies set towards ending poverty in the third world, the policy interventions attributed to the MDGs, and the international community forms a critical part of the exploration. Therefore, throughout the paper, reference to the MDGs, the international community, and globalization are inevitable. Strategies towards Ending Poverty in the Third World When considering the interventions being developed towards ending poverty in the third world, one should consider the causes of poverty and their role in determining the responses towards poverty by all key players including inhabitants of third world countries, potential donors, and those from developed countries or economies. Among some of the determined causes of poverty in the third world first is the high and underdeveloped population in the third world attributed to lack of ability among the people, unwillingness to change traditional ways and customs, lack of proper resource management, lack of attempt at self-improvement, laziness, and lack of knowledge (Panadero and Vazquez, 2008, p. 574). The second cause is poor governance in third world countries attributed to corruption and inefficiency among the governments, while the third cause is exploitation of the third world countries by other countries especially developed countries and by the world economy and banking systems, and lack of an open market system. The fourth cause of poverty in the third world according to Panadero and Vasquez (2008) is war whereby the governments spend too much on arms and more is spent in restoring the country after a war or keep the country afloat in the course of the war. Lastly, third world poverty is attributed to natural causes that include diseases, pests and insects that destroy crops, natural disasters because of poor climatic conditions and lack of environmental friendly knowledge. Alleviation and eradication of poverty in the third world will take the effort of the inhabitants of these countries, those from the developed economies and the organizations key to development such as UNDP, World Bank and the IMF. The effort should focus on strategies that will facilitate reduction and eventual eradication of poverty, and ensuring people from the third world gain the knowledge and provisions needed to prevent them from going back to their current status. Agreeably, the eradication of poverty in the third world requires a multidimensional focus that does not only concentrate on reducing income poverty, which has been the focus of many interventions, but also include interventions geared towards reduction of human deprivation in all dimensions (Chopra, 2005, p. 52). To achieve a global reduction of poverty as per the MDGs by 2015, the third world countries comprising the world’s poorest countries need to pursue wide ranges of reforms with developed nations responding to the effort through improved trade terms and increased aid. According to Chopra (2005), action is critical in ensuring global financial stability and ensuring that poor countries are at par with developed nations in the adoption of technology and in scientific and medical research (p. 52). Further, the wealthy nations must open their markets to the products of the poor countries, with aid and debt relief increased to help the poor countries help themselves without the interference of the wealthy nations, which has marked most of the intervention programs. Nevertheless, the poor nations need to give voice to their need and influence decision-making in international forums, noting that in most forums the powerful developed countries make much of the decisions related to the development of the poor nations. Therefore, for the world to end third world poverty and ensure that the global platform allows equal opportunities and competition to all, the international community needs to review existing intervention programs. Among interventions that can aid the process of ending third world poverty that have been part of the implemented strategies, include one promoting equal opportunity through the expansion of economic opportunities for poor people through the stimulation of overall growth (Chopra, 2005, p. 51). Additional strategies towards offering equal opportunity is building up the poor countries assets and increasing the asset returns through market and non-market action. As stated in the discussion of causes of poverty, one of the mentions causes is an underdeveloped population; therefore, offering opportunities for economic expansion will help these populations begin thriving thus facilitate a reduction of poverty. Furthermore, another attributed cause of poverty is a closed market that does not allow the poor nations to promote their products in the developed nations; however, creation of opportunities through the opening of markets will enable them access the international market. Additionally, the promotion of assets especially within the international community is another strategy of providing equal opportunities to the poor nations. Second intervention is facilitating empowerment through adoption of accountability in state institutions and response to the needs of the poor people, as well as strengthening the participation of poor people in political processes and local decision-making (Chopra, 2005, p. 52). Further, empowerment requires people be encouraged to participate in political processes, local decision making, and eradicating social barriers that contribute to gender, ethnic, racial, religious, and social distinction. Dealing with unaccountability in state institutions including governments ensures successful address of some of the cause of poverty, which is corrupt government. Further, strengthening people’s participation in decision-making will provide the link between the people, the leadership, and the resources resulting in better resource usage that has been lacking in many third world countries. The third factor in addressing poverty in the third world is enlargement of security through reduction of people’s vulnerability to ill health, economic shocks, policy induced dislocations, natural disasters, and violence (Chopra, 2005, p. 52). Notably, health is a significant factor in development because when people are healthy they are more likely to engage in economically productive activities compared to when they are ill or undergoing natural circumstances that reduce their efficiency. Security should also include protection from violence, and helping the people deal with adverse shocks when they occur. Maintenance of security is important to offer people an opportunity to work towards developmentally beneficial activities without fear of violence, disease, or natural disasters, and incase such events occur people should know their country has the capacity to address them and restore order. The implementation of some of these factors as discussed in the subsequent section has been ongoing in many parts of the third world realizing a steady decline in poverty. However, the number of the poor continues to be significant denoting a failure in the effective of the strategies, and requiring developmental agencies and developing nations to either adopt different strategies or approach the existing strategies from another side. Nevertheless, one cannot claim that the international community has not been trying to meet the MDGs especially in the third world and some poor parts of the developed nations.
