The fundamental essence covered the central role of representation of meaning within signs of photographic images captured of the September 11, 2001 terrorist attacks on the United States of America, in Time magazine’s September 11, 2001 special edition. This was done in order to determine how sign representation appeared in relation to philosophical sociologist Jean Baudrillard’s concepts of simulacra, simulation, hyperreality and massification. These concepts were assessed in relation to dominant theme categories and sub themes contained in the photographic images of this publication by means of a qualitative thematic content analysis. The motivation for the selection of this event was based on its magnitude and worldwide consequences. Furthermore, the images were selected in the specified mass media medium of Time magazine based on Baudrillard’s inference that consumption within a society is based on the controlling codes of society and one of these codes is the mass media. Hence the mass media have control over the value which a sign will have in a specific society thus giving it meaning, and on its inception AOL/Time Warner was the largest media conglomerate ever formed. Therefore what messages they deem as significant to be disseminated will become a controlling code of what signs have which meaning on a global scale. Moreover, Baudrillard believes that the mass media create a dominant belief system, which creates mass ideas and one of the ways in which massification occurs is through the use of images. As such, visuals play a powerful role in the representation of major world events. Particularly photographs because they are a reflection and thus form part of the registration process of what is being witnessed, where in this case it was the terrorist attacks of September 11, 2001. Hence visual images of world events are displayed globally by the mass media, which in turn propagate their own mediation of events and in this particular case terrorism fuelled the massified information that was dispersed. This information is circulated on a global scale via the mass media based on what will generate the most capital by creating what is consumable. What has occurred in the mass media arena is that ownership structures have changed and today there is a major increase in media conglomerates with media power being in fewer and fewer hands. This leads to information flow that is skewed by a specified ideology, which in the case of Time magazine would be a western ideology. In line with the established motivation as well as the dominance of visual supplements in much of the coverage of September 11, 2001, the overriding research problem was to determine how meaning was represented in the signs, from a Baudrillardian perspective, in the dominant themes in selected visuals in Time magazine’s September 11, 2001 special edition. Based on the research, a key underlying finding revealed the idea that in mass mediated cultures everything is a sign and representation of the real and therefore the real loses meaning and is replaced by a hyperreal and thus image and form devour the real and audiences are seduced by the values of signs. / Andrea Crystal

Magister Public Health - MPH / The study utilized a qualitative case study design to explore the problem of poor access to ART in Benue State. PLWHAs, policy makers, program managers and health workers were involved in an effort to describe the factors influencing access to ART in the State. Semi structured interviews, exit interviews and focus group discussions were used. To analyse the findings, categorization was done into facilitators and barriers to access, in addition to the ways respondents believe these barriers can be overcome. Other sub-themes were also identified and sorted. Themes were linked to direct quotes from the respondents. Additional literature review was done to review available information on the themes identified. Facilitators of access included free cost and increased number of sites; beneficial effects of ART; disclosure, membership in a support group and having a treatment partner. Barriers included stigma and discrimination; hunger, poverty, transportation and opportunity costs; hospital factors; non-disclosure; inaccurate knowledge and perceptions about HIV and ART; certain religious beliefs and advice; coverage, capping of services and fear of non-availability of ART. In addition to stigma, patients bypass closer ART access points to further away hospitals because of business opportunities; financial assistance; perceived better standard of care and hope that a cure, when found, will be more accessible to patients in bigger hospitals. / South Africa

Magister Philosophiae - MPhil / This study is aimed at empirically examining health seeking behaviours in terms of illness response on household level at South Africa using 2007 General Household Survey and other relevant secondary sources. It provides an assessment of health seeking behaviours at the household level using individuals as unit of analysis by exploring the type of health care provider sought, the reason for delay in health seeking and the cause for not consulting. This study also assesses the extent of dissatisfaction among households using medical centres and this factor in health care utilisation is considered as the main reason for not consulting health care services. All the demographic and health seeking variables utilised in this study are controlled for medical aid cover because it is a critical variable in health care seeking. Therefore this study makes distinction on illness reporting and they type of health care consulted by medical aid holders and non medical aid holders. Statistical analyses are conducted to explore and predict the way in which demographic variables and socio economic variables affect health care seeking behaviours. / South Africa

Magister Public Health - MPH / At the end of 2008, Nigeria had the third largest number of people living with HIV/AIDS(PLWHA) in the world, with an estimated 2.95 million people and an average prevalence rate of 4.6%. According to the 2008 prevalence survey, prevalence rates in Nigeria’s 36 states and capital ranges between 1.0% in Ekiti State, to 10.6% in Benue.In Benue State, as at December 2008, only 12% of those requiring treatment were enrolled in an ART programme and only about half of the 23 Local Government Areas (LGAs) had a health centre providing ART services. There are several possible causes for poor coverage of ART services. This study explores some of the barriers preventing PLWHAs from accessing treatment in Benue State.The study utilized a qualitative case study design to explore the problem of poor access to ART in Benue State.

Master of Public Health - MPH / The World Health Organisation estimates that more than 50% of medicines are inappropriately used globally. The situation is worst in developing countries such as Nigeria, where irrational prescribing practices account for wastage of resources, catastrophic medicines costs and poor access to health services. In 2005, the Social Health Insurance Programme was launched as a financially sustainable model to achieve cost effective and affordable health care services including medicines. This study investigated prescribing practices and availability of medicines in the Social Health Insurance Programme in accredited public sector secondary hospitals in the Federal Capital Territory, Nigeria.Methodology:The study is a descriptive, cross-sectional and retrospective survey of prescriptions of insured outpatients in the Federal Capital Territory, Nigeria. Four hospitals were selected by stratification of thirteen (13) public secondary hospitals in the territory into urban/peri-urban areas, followed by random selection of two hospitals from each stratum.A total of seven hundred and twenty (720) retrospective prescription encounters of insured outpatients were systematically selected from encounters between July 2009 and June 2010 at the selected facilities. Data on prescribing practices and the extent to which prescribed medicines were provided were assessed with the use of modified WHO/INRUD indicators. Descriptive statistics were generated with Epi-info (version 3.4.3) and SPSS (version 17.0)Results: Out of the seven hundred and twenty (720) prescriptions that were assessed analgesics/NSAID, antibiotics, antimalarials and haematinics/vitamins collectively accounted for 67.4% of the medicines prescribed.A comparison of the results with WHO/Derived reference values showed that average number of medicines prescribed per prescription (3.5 ±1, p<0.001) and the rate of antibiotic prescribing (53.7%, p=0.009) were higher than the WHO recommended ranges of (1.6-1.8) and (20.0- 25.4%) respectively.The use of generic names in prescribing (50.9%, p<0.0009) and medicines prescribed from the Essential Medicine List (74.2%, p=0.05) were considerably lower than the standard (100%) However, the rate of injection prescribing (12.49%, p=0.4) was within the recommended range (10.1–17.0%).The study also found that 85.1%, (p=0.001) of prescribed medicines were dispensed, while 93.4% (p=0.256) of essential medicines were dispensed which was lower than the recommended standard (100%). Overall, only 58%,(p<0.0001) of patients had all prescribed medicines completely dispensed and this was significantly lower than the desired standard (100%.) in social health insurance programmes.Conclusions:The findings of this study show trends toward irrational prescribing practices as characterized by poly-pharmacy, overuse of antibiotics, sub-optimal generic prescribing, as well as poor adherence to the use of NHIS-Essential Medicine List. There was sub-optimal provision of prescribed medicines. These are potential threats to the scheme‟s goal of universal access to health care in the year 2015. Pragmatic multi-component interventions are recommended to promote rational prescribing and improve equity in access to essential medicines.

Following thesis deals with the question of how the four main television channels in the Czech Republic process and create news. Based on her own observation, the author has tried to find and describe the main tendencies in the field of the television news reporting. The thesis thus gives a general overview of the newsmaking routine according to the specialized literature, but also provides the reader with the results of those observations. The work consists of two parts: the theoretical and practical. The first part starts with the basic components of the news reporting, followed by a more detailed description of the television part. The last part of the theory includes the development trends in the television news and deals with the visual and audial components of the news as well as the role of the reporter in it. The latter includes the verbal as well as non-verbal communication, i.e. linguistics of the news and means of expression of the reporters and news anchors as well as the importance of the reporter and the part he plays in the news. The practical part analyzes given pieces of news, using the information provided in the previous part; the analysis is thus based on the above stated criteria. These analyses should then help to describe the way television works with the news and...

Content analysis of The Dallas Morning News focuses on sources, bylines, photographs, and main characters to determine the quantity and quality of portrayals of women. The study included front pages and main local news pages during one week each from 1950, 1960, 1970, 1980, and 1990. Change was charted by year for both sexes. In 1950, few representations of women were included and many were stereotypical. Some stereotyping persisted in 1990, and men outnumbered women more than 3 to 1 as story sources, nearly 3 to 1 in front-page bylines, more than 2 to 1 in photographs, and more than 2 to 1 as main characters. Women still lag behind men, despite feminists' efforts to improve coverage.

This thesis aimed to elucidate the demographic characteristics associated with elevated or reduced rates of pneumococcal conjugate 13 (PCV13) vaccination. A retrospective cohort study was performed using the Truven Health MarketScan® Database. Three cohorts were created corresponding to populations for which the CDC recommends PCV13 vaccination. Cohort 1: children < 36 months of age. Cohort 2: adults 19-64 years of age with high infection risk. Cohort 3: adults > 65 years of age. Odds of having a PCV13 claim were calculated for each cohort. For Cohort 1, 78% out of a total of 353,214 subjects had a sufficient number of PCV13 doses to meet CDC recommendations. For Cohort 2, 3.7% out of a total of 673,157 subjects had a PCV13 claim. For Cohort 3, 18% of 1,262,531 subjects had a PCV13 claim. Odds of vaccination were generally lower in younger subjects, those with fewer outpatient claims, and those with residence in the Northeast and South regions. In Cohort 2, odds were reduced in subjects with generalized malignancy. Gender and urban residence were poor predictors of vaccination status. By understanding the demographic factors associated with lower rates of vaccination, clinicians may more effectively direct their efforts to increase pneumococcal vaccination coverage.

In this thesis, we proposed the use of device-to-device (D2D) communications for extending the coverage area of active base stations, for public safety communications with partial coverage. A 3GPP standard compliant D2D system level simulator is developed for HetNets and public safety scenarios and used to evaluate the performance of D2D discovery and communications underlying cellular networks. For D2D discovery, the benefits of time-domain inter-cell interference coordi- nation (ICIC) approaches by using almost blank subframes were evaluated. Also, the use of multi-hop is proposed to improve, even further, the performance of the D2D discovery process. Finally, the possibility of using multi-hop D2D communications for extending the coverage area of active base stations was evaluated. Improvements in energy and spectral efficiency, when compared with the case of direct UE-eNB communi- cations, were demonstrated. Moreover, UE power control techniques were applied to reduce the effects of interference from neighboring D2D links.

Wireless Sensor Networks (WSNs) are widely used for various civilian and military applications, and thus have attracted significant interest in recent years. This work investigates the important problem of optimal deployment of WSNs in terms of coverage and energy consumption. Five deployment algorithms are developed for maximal sensing range and minimal energy consumption in order to provide optimal sensing coverage and maximum lifetime. Also, all developed algorithms include self-healing capabilities in order to restore the operation of WSNs after a number of nodes have become inoperative. Two centralized optimization algorithms are developed, one based on Genetic Algorithms (GAs) and one based on Particle Swarm Optimization (PSO). Both optimization algorithms use powerful central nodes to calculate and obtain the global optimum outcomes. The GA is used to determine the optimal tradeoff between network coverage and overall distance travelled by fixed range sensors. The PSO algorithm is used to ensure 100% network coverage and minimize the energy consumed by mobile and range-adjustable sensors. Up to 30% - 90% energy savings can be provided in different scenarios by using the developed optimization algorithms thereby extending the lifetime of the sensor by 1.4 to 10 times. Three distributed optimization algorithms are also developed to relocate the sensors and optimize the coverage of networks with more stringent design and cost constraints. Each algorithm is cooperatively executed by all sensors to achieve better coverage. Two of our algorithms use the relative positions between sensors to optimize the coverage and energy savings. They provide 20% to 25% more energy savings than existing solutions. Our third algorithm is developed for networks without self-localization capabilities and supports the optimal deployment of such networks without requiring the use of expensive geolocation hardware or energy consuming localization algorithms. This is important for indoor monitoring applications since current localization algorithms cannot provide good accuracy for sensor relocation algorithms in such indoor environments. Also, no sensor redeployment algorithms, which can operate without self-localization systems, developed before our work.
