The introduction of FMD into the US would have serious economic and societal effects on the livelihoods and sustainability of affected livestock producers. Livestock producers serve as an important line of defense in both detecting an introduction of FMD as well, helping to prevent disease spread. However, due to the complexity of moral, social, and economic issues surrounding the control of highly contagious diseases, producer cooperation during an outbreak may not be assured. This study was conducted using a mixed-methods approach, including qualitative analysis of interviews and quantitative analysis of a postal survey, in order to explore the factors likely to influence producer cooperation in FMD detection and control in Texas. Reporting of cattle with clinical signs of FMD in the absence of an outbreak was related to producers´ beliefs about the consequences of reporting, beliefs about what other producers would do, trust in agricultural agencies, and their perception of the risk posed by FMD. During a hypothetical outbreak, intentions to report were determined by beliefs about the consequences of reporting, and perception of the risk posed by FMD. Intentions to gather and hold cattle when requested during an outbreak were determined by beliefs about the consequences of gathering and holding, beliefs about barriers to gathering and holding, trust in other producers, and perception of the risk posed by FMD. Compliance with animal movement restrictions was determined by experiential attitudes, beliefs about the availability of feed, space, and disinfection procedures, beliefs about what other producers would do, and perception of the risk posed by FMD. Recommendations for improving producer cooperation include targeting specific beliefs in both planning and communication, increasing transparency in the post-reporting process, planning for and communicating plans for maintaining business continuity in order to better inform risk perception, and partnering with organizations to ensure sustained and meaningful communication that supports trust between producers within the affected agricultural community.

Thesis (MSc)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Successful antiretroviral therapy (ART) depends on appropriate use of antiretroviral agents; which ultimately prevents replication of Human Immunodeficiency Virus (HIV) thus delaying clinical progression of the disease. This study explored how HIV status disclosure affects adherence to antiretroviral therapy at Mamelodi Hospital, using a convenience sampling method with a sample size of 50 adults above 18 years who were on treatment for a minimum of two years prior to the study. An interview protocol was used to uncover patients’ demographics, sexual orientation, and HIV status disclosure, adherence to antiretroviral drugs, drug side effects, how often they missed their doses and how HIV status disclosure / non-disclosure affected their adherence to treatment. Patients’ medical records were assessed to validate and correlate the information obtained from the interviews. The scientific test results used were the CD4count and Viral loads which are used to monitor the HIV/AIDS disease progression. All partakers involved in the study made their HIV status known and reported taking their medicines regularly. The patients’ CD4 count and VL were verified, the CD4 count has shown an upward trend while the VL load showed a downward trend in keeping with patients who are adhering to ART. The majority of participants (54% or 27 patients) reported they had never skipped taking their medication. The participants also reported they had taken their medicine in front of other people and they constituted 74% (37) of the group. Of this 74%, 78.38% (29 patients) said it was because they had disclosed their status. This observation supports the fact that if you have disclosed your HIV status, you have better chances of adhering to prescribed medication. Findings from the study at Mamelodi Hospital revealed that for as long as one has disclosed their HIV status, the outcome of treatment adherence will be better. The only shortfall noted was lack of partakers who did not divulge their HIV status thus a comparison could not be done. It was acknowledged that some participants in the study might have reported disclosure of their HIV status to be in good favour of the researcher to create an impression that they are adhering to their medication. The study has confirmed the existence of a relationship between HIV status disclosure and adherence to ART. / AFRIKAANSE OPSOMMING: Suksessvolle antiretrovirale terapie (ART) hang af van die toepaslike gebruik van antiretrovirale middels, wat replikase van die MI-virus verhoed, en dus die kliniese vordering van die siekte vertraag. Hierdie studie het ondersoek hoe die bekendmaking van MIV-status die gehoorsaamheid tot ART beïnvloed het by die Mamelodi Hospitaal. ‘n Gerieflikheid-streekproef met ‘n groote van 50 volwassenes bo 18 jaar is gebruik en die deelnememers moes ten minste vir twee jaar voor die studie reeds op behandeling gewees het. Data is deur middel van onderhoude ingesamel, met die doel om pasiënte se demografiese inligting, seksuele orientasie, MIV-status, gehoorsaamheid tot ART en newe-effekte van ART in te samel. Pasiënte se mediese rekords is nagegaan om die inligting wat uit die onderhoude verkry is te bevestig. Die wetenskaplike toetse wat gebruik is, was die CD4-telling en virale lading wat gebruik word om MIV/Vigs te monitor. Al die deelnemers het hul MIV-status bekend gemaak en aangedui dat hul hul medikasie gereeld gebruik. Die pasiënte se CD4-tellings en virale lading is bevestig, die CD4-tellings het ‘n opwaartse neiging getoon terwyl die virale lading ‘n afwaartse neighing getoon het. Die meerderheid van die deelnemers (54%) het aangedui dat hul nog nooit hul medikasie oorgeslaan het nie. 74% van die deelnemers het aagedui dat hul hul medikasie voor ander mense neem - hul noem dat dit as gevolg van die feit is dat hul hul status bekend gemaak het. Dit ondersteun die feit dat mense wie hul status bekend maak beter kanse het om gehoorsaam hul medikasie te gebruik. Die studie by die Mamelodi Hospitaal toon dat solank mense hul MIV-status bekend maak, hul meer gehoorsaam is teenoor die gebruik van hul medikasie. Die studie bevestig dus die verband tussen bekendmaking van MIV-status en gehoorsaamheid tot ART.

Thesis (MPhil)--Stellenbosch University, 2013. / Bibliography / ENGLISH ABSTRACT: When South African President Thabo Mbeki began doubting that HIV was the cause of AIDS in the late 1990s, failed to provide AIDS medication and stalled its introduction, openly supported HIV pseudoscientists and doubted HIV statistics, one of the most widely reported debates in the country’s history emerged. When two independent 2008 studies found that the death of approximately 330 000 South Africans could have been prevented between 1999 and 2007 if President Mbeki’s HIV policy made provision for AIDS medication, the AIDS debate was re-introduced, and it was these findings that provided the motivation for this study. The purpose of this study was to provide a historical perspective on HIV reporting in the media during Mbeki’s presidency in order to answer how the media reflected and reported on his HIV policy, and also to provide possible reasons for the way the media reported on the matter. Research has shown that the government (particularly President Mbeki and his health ministers) and AIDS social movement organisations (particularly the Treatment Action Campaign [TAC]) were the main actors framing the AIDS epidemic in South Africa. Thus, this study examined the media’s HIV trail in reporting on these actors’ responses and counter-responses by means of content analysis. Qualitative analysis, in the form of questionnaires sent to health journalists who reported on HIV during this period, was completed in order to provide the possible reasons for the media’s reporting style. During the content analysis it was found that the media reporting was mostly positive towards the TAC and mostly critical towards Mbeki and his government, and the results of the questionnaires verified this, but also provided reasons why the media were mostly critical of Mbeki and his government. One principal reason was that the government’s policies on HIV were so blatantly contrary to scientific evidence and medically unethical that it was the media’s duty to fulfil their watchdog and surveillance role. / AFRIKAANSE OPSOMMING: Toe die Suid-Afrikaanse president, Thabo Mbeki, in die laat jare negentig begin het om die oorsaak van VIGS in twyfel te trek, daarin misluk het om VIGS-medikasie te verskaf en produksie daarvan vertraag het, en openlik MIV-pseudowetenskaplikes ondersteun het en MIV-statistiek bevraagteken het, het ’n debat met moontlik van dié wydste nuusdekking in die geskiedenis van die land posgevat. Die VIGS-debat het weer op die voorgrond beland nadat twee onafhanklike studies in 2008 bevind het sowat 330 000 Suid-Afrikaners se dood kon tussen 1999 en 2007 vermy gewees het indien president Mbeki se MIV-beleid voorsiening gemaak het vir die verskaffing van VIGS-medikasie. Hierdie bevindinge het die motivering vir die studie verskaf. Die doel van hierdie studie was om ’n historiese perspektief van die mediadekking van MIV tydens Mbeki se presidentskap te verskaf om sodoende vas te stel hoe die media die debat oor Mbeki se MIV-beleid weerspieël het, maar ook om die redes te bepaal vir die manier waarop die media oor die kwessie berig het. Navorsing het getoon die regering (spesifiek president Mbeki en sy gesondheidsministers) en aktivistegroepe (spesifiek die Treatment Action Campaign [TAC]) was die hoofkarakters betrokke by die fokussering van die VIGS-epidemie in Suid-Afrika. Dus het hierdie studie probeer om die media se MIV-spore met betrekking tot beriggewing oor hierdie akteurs se stellings en reaksies deur middel van inhoudanalise te bestudeer. Kwalitatiewe analise in die vorm van vraelyste wat aan gesondheidsjoernaliste gestuur is wat in hierdie tydperk beriggewing oor MIV gedoen het, is gebruik om moontlike redes te verskaf vir die manier van beriggewing. Tydens die inhoudanalise is bevind dat mediadekking meestal positief teenoor die TAC was en meestal negatief teenoor Mbeki en sy regering. Die resultate van die vraelyste het dít bevestig, en redes verskaf waarom die media meestal krities was teenoor Mbeki en sy regering. Een van die vernaamste redes was dat die regering se beleidsrigtings met betrekking tot MIV so blatant teen wetenskaplike bewyse gekant was en boonop medies oneties was, dat dit juis die media se plig was om die rol van waghond te speel.

FundaÃÃo de Amparo à Pesquisa do Estado do Cearà / CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / A subnotificaÃÃo de casos de Aids representa um dos principais problemas enfrentados pela vigilÃncia epidemiolÃgica da Aids. Dessa forma este trabalho teve como objetivo, conhecer a subnotificaÃÃo dos casos de Aids em adultos no municÃpio de Fortaleza, nos anos de 2002 e 2003, aplicando o mÃtodo de captura e recaptura. Estimou-se ainda, a subnotificaÃÃo em dois hospitais de referÃncia para Aids, Hospital SÃo Josà â HSJ e Hospital Geral de Fortaleza â HGF. Nesse estudo foram utilizados dados secundÃrios do Sistema de InformaÃÃo de Agravo de NotificaÃÃo â Sinan, Sistema de Controle de Exames Laboratoriais - Siscel e Sistema de InformaÃÃes sobre Mortalidade - SIM, comparando os trÃs sistemas e considerando como notificados os casos confirmados no Sinan. Os casos foram emparelhados no Programa RecLink II. ApÃs o emparelhamento dos casos foram selecionados os elegÃveis para aplicaÃÃo do mÃtodo de captura e recaptura, utilizando os estimadores de Lincoln-Petersen e o de Chapman. A subnotificaÃÃo estimada para Fortaleza foi de 33,1%, e 14,1%, tendo como referÃncia o Sinan e comparando com as fontes Siscel e SIM, respectivamente. Para os hospitais S. Josà e HGF a subnotificaÃÃo foi de 5,4% e 90,5%, na mesma ordem, comparando o Sinan com o Siscel. Este trabalho demonstrou uma elevada subnotificaÃÃo de casos de Aids no municÃpio de Fortaleza nos anos de 2002 e 2003 e que a subnotificaÃÃo quando avaliada por fonte, comparando o Siscel com o Sinan, ela à mais de duas vezes superior à estimada quando comparada à das fontes SIM/Sinan, demonstrando ser o Siscel uma importante fonte de notificaÃÃo de casos de Aids. Quanto à subnotificaÃÃo nas duas unidades de SaÃde, observa-se um percentual bem mais elevado para o HGF. O Programa RecLink II mostrou ser uma opÃÃo simples para o reconhecimento dos casos nÃo notificados no Sinan e em relaÃÃo a tÃcnica de captura e recaptura, pode ser utilizada de forma simples e rÃpida e com baixo custo, comparando os sistemas dois a dois em pesquisas pontuais. Diante dos achados nesse estudo, recomenda-se que o Sinan-Aids seja comparado em periodicidade mensal, com todas as fontes de informaÃÃes disponÃveis que possam contribuir para reduÃÃo da subnotificaÃÃo de Aids / Underreporting is one of the major problems challenging epidemiologic AIDS surveillance. The objective of this study was to estimate the level of underreporting of AIDS in adults in Fortaleza in the period 2002-2003 using the capture-recapture method. In addition, the level of underreporting at two hospitals for AIDS referral (Hospital SÃo Josà â HSJ, and Hospital Geral de Fortaleza â HGF was estimated. The study relied on three secondary databases: SINAN (national disease surveillance), SISCEL (laboratory test control) and SIM (mortality information). The systems were compared and cases confirmed by SINAN were considered as reported. Cases from the two databases were paired using the software RecLink II. Subsequently cases eligible for the capture-recapture method were selected using the Lincoln-Petersen and Chapmam estimators. The levels of underreporting were estimated at 33.1% and 14.1% for SISCEL and SIM, respectively. Underreporting for SISCEL was 5.4% at HSJ and 90.5% at HGF. The study shows a considerable level of underreporting of AIDS cases in Fortaleza for the period 2002-2003 and suggests that SISCEL is an important source of AIDS reporting considering that it allowed to detect levels of underreporting more than twice the estimates derived from the sources SIM and SINAN. The level of underreporting was considerably higher at HF than at HSJ. The software RecLink II was shown to be a practical tool for identifying cases not reported to SINAN. The capture-recapture method is a simple, time-saving and inexpensive way to compare two systems when necessary. Considering the findings of the present study, SINAN-AIDS should be compared monthly with all relevant information systems in order to reduce levels of AIDS underreporting

【研究緣起與問題】2003年春季，SARS在全球造成一陣轟動，同時也重創全球的經濟，如今SARS會不會再來？政府如何因應？政府如何監測疫情？如何防治疫情？如果SARS等新興及再浮現感染症 （Emerging and Re-emerging Infectious Diseases）出現時，負責全國傳染病防治任務的行政院衛生署疾病管制局是如何作好全國傳染病防治工作呢？中央及地方主管機關之溝通，如何共同消除指責與誤會，發揮團隊精神，如何共同作好全國傳染病防疫任務，爭取公眾對政府之瞭解並加以支持，同時防止任何可能之攻擊，才是全民之福祉。故以「全國傳染病通報系統」的績效，其所仰賴之溝通通路之問題研究，是本研究的動機。了解「傳染病通報管理系統(WEB版)」最大的問題及新興傳染病（如SARS）防治通報的問題及「傳染病通報管理系統」最需要改進之的地方，是本研究的目的。 【研究方法與資料】本研究採取量化與質化並重的方法，以網路問卷方式的進行問卷調查，問卷對象為全國使用傳染病通報管理系統之相關人員，問卷問題內容的設計主要的型式含有開放式問卷（Open –Ended Question）、封閉式問卷（Close-Ended Question）及混合型問卷（Mixed Question）三種。同時以九十二年針對新興傳染病SARS期間為例，深度訪談當時任職於中央與地方負責傳染病防治權責具代表性者五位主管進行訪談，瞭解受訪者對新興傳染病如SARS防治的問題及「傳染病通報管理系統」最需要改進之的地方，以彌補問卷調查法無法深入瞭解到問題之缺點。 【研究結論與建議】 一、根據筆者初步研究經問卷的實證調查之後，從問卷分析資料顯示，使用者使用電腦的時間愈久，對以新版為溝通工具滿意度愈低；而愈瞭解通報系統的使用者，其以新版為溝通工具滿意度愈高，愈滿意新版改進之電腦網路溝通效果。顯示新版的通報系統在設計的操作介面與程序上，沒有人性化，作業內容繁多、需輸入的項目、資料太繁瑣、版面太繁瑣等，反而徒增使用者的困擾；而愈瞭解通報系統的使用者，其對新版的滿意度越高，表示對於使用者在操作上的教育訓練仍須加強，才能發揮新版通報系統的成效。 二、從敘述統計分析中發現： 受訪者對「訊息異動通知作業流程滿意」的使用滿意度的平均數最高，平均數為2.8095表示：較為滿意。「通報作業流程滿意嗎」的使用滿意度的平均數最低，平均數為2.3934，受訪者表示：較為滿意。以新版為溝通工具整體溝通滿意情形，平均數為2.558滿意。 三、開放式問卷分析資料顯示，花太多時間、速度太慢、網路的頻寬過窄又不穩定或無法登錄、作業內容繁多、作業流程問題、資訊管理問題及功能增添與建議等部分。 四、根據筆者初步研究深度訪談之後，彙整中央主管機關及地方主管機關的訪談核心二部分的問題與建議。 五、研究建議： 綜合問卷調查及深度訪談結果，提出政策層面、組織溝通層面、管理層面、實務操作層面等之建議。 【關鍵字】傳染病通報系統、嚴重急性呼吸道症候群(severe acute respiratory syndrome, SARS)、組織溝通、溝通通路、行政院衛生署疾病管制局 / 【Background and Issues】 In the spring of 2003, SARS outbreaks devastated the whole world; they also heavily damaged the world economy. Will SARS come back? How can governments manage it? How can government monitor the epidemics? How can we control the infection? When emerging and re-emerging infectious diseases such as SARS appear, how can the Center for Disease Control of the Department of Health, an organization in charge of national disease control, plan and execute measures for the control of communicable diseases? Effective communication between the central and the local competent authorities to remove together blames and misunderstanding, to develop team spirit, to attain jointly the goal of disease control, to solicit understanding and support of the public to the government, and to prevent any likely attack are some of the considerations in improving the welfare of the public. The reason of the present study was to understand, through the achievements thus far of the National Communicable Disease Reporting System, issues involved in the communication channels. The purposes of the study were to understand the major problems of the Communicable Disease Reporting and Management System (the Web version), issues involved in the reporting of emerging infectious diseases, and areas of the Communicable Disease Reporting and Management System where improvement was most urgently needed. 【Method and Materials】 Both the quantitative and qualitative methods were used. Questionnaire interview was conducted through the web to persons using the Communicable Disease Reporting and Management System throughout the country. The questionnaire contained open-end questions, closed-end questions and questions of mixed types. At the same time, to understand in depth areas not properly covered by the questionnaire interview, five key persons responsible for disease control at the time of the SARS outbreaks in 2003 at the central and the local levels were interviewed to understand their attitudes toward the control of emerging infectious diseases such as SARS, and the improvement most urgently needed for the Communicable Disease Reporting and Management System. 【Results and Recommendations】 1. Preliminary findings from analysis of the questionnaire interview showed that users became less satisfied with the new version communication means the longer they were in use of computers. Users who knew more about the use of the reporting system were more satisfied with the new communication means, were at the same time, more satisfied with the communication effects of the improved version. These facts suggested that the new reporting system was less user-friendly in the designing of interface and procedures. The system required more work, more detailed inputs, and thus added additional burdens on the part of the users. The more the users understood the reporting system, their satisfaction was higher, indicating that, for the new version reporting system to function in full, training of the users in the use of the system should be strengthened. 2. From the descriptive analysis, it was found that the average score of user satisfaction on the “information change reporting procedures” was as high as 2.8095, suggesting that the users were fairly satisfied. The satisfaction score on “reporting procedures” was the lowest at 2.3934. The overall satisfaction score on the use of the new version as a communication means was 2.558. 3. Findings from the open-end questions gave the following recommendations: taking too much time, too slow, frequency of the web too narrow, unstable, and unable to load, too detailed, issues related to operational procedures, issues related to information management and additional functions, etc. 4. By analysis of the in-depth interview, some issues were raised and recommendations made to the central and the local competent authorities. 5. Through questionnaire survey and in-depth interview, some recommendations concerning policies, organizational communication, management and practical operation were made. 【Key Words】 Communicable Disease Reporting System, SARS (Severe Acute Respiratory Syndrome), organizational communication, communication channels, Center for Disease Control, the Department of Health

This research focused on the experiences of HIV disclosure to significant others amongst people living with HIV. The aim of the research was to explore how people living with HIV experience disclosure of their HIV positive status to their significant others. The social constructionist perspective was utilized to gain a deeper understanding of the experience of HIV positive status disclosure to significant others. The study’s sample comprised of five participants who were recruited using purposive sampling strategy. Data was collected with using face to face semi structured interviews. Themes were extracted and analysed using thematic content analysis. An analysis was made as to whom participants choose to disclose to, the reaction of the people they disclosed to, as well as their reasons for disclosing. Results were reported as the participants’ experiences and noted as is or unadulterated. / Psychology / M.A. (Psychology)

The purpose of this study was to develop a laboratory based Comprehensive Care, Management and Treatment of HIV and AIDS (CCMT) programme status reporting system using a methodological research study design. Quantitative data was collected using a request form and qualitative data was collected using structured questionnaires. For the study 1190 eligible CD4 samples were received, of which 1004 (84%) had a valid CCMT programme status. Overall 32% of the CD4 samples had a pre-ART status (n=383) and 52% had an ART status (n=621). The remaining 16% of CD4 samples (n=186) did not have a valid CCMT programme status. A pre-ART register was generated and assessed using a structured questionnaire. Based on the study findings a recommendation has been made to adopt the two-tick design for all NHLS request forms where programmatic data is collected. Additionally the CCMT programme status reporting system is recommended for rollout to other health districts / Health Studies / M.A. (Public Health with specialisation in Medical Informatics)
