School leadership and teachers with HIV/AIDS : stigma and discrimination in Gauteng Province schoolsMoyo, Zvisinei 09 1900 (has links)
Since the discovery of HIV/AIDS in the late 1980s, the pandemic has become the leading cause of death in South Africa and one of the leading causes worldwide. South Africa has the largest number of people infected with HIV/AIDS in the world. South African teachers, in particular, have experienced unparalleled challenges as a result of HIV/AIDS.
This qualitative research study was designed to explore how principals handle the sensitive HIV/AIDS-related issues affecting teachers in schools in South Africa’s Gauteng Province. The study was carried out within the constructivist paradigm. The narrative inquiry research design within the qualitative research approach was used with purposive and network sampling of participants. The sample consisted of ten handpicked principals and eight teachers living with HIV/AIDS accessed through network sampling from around the province. Data were collected through narrative interviews and the compilation of a reflective diary. The data were analysed according to the qualitative content analysis method. Consent was elicited from participants with confidentiality, anonymity and trust maintained throughout the study.
The participants’ most common responses were that teachers living with HIV/AIDS are faced with the dilemma of disclosure and stigma and discrimination. This research showed that principals are experiencing a range of challenges due to teachers living with HIV/AIDS. The goals of quality education are often defeated because of the challenges surrounding teachers living with HIV/AIDS. Once teachers succumb to the opportunistic illnesses associated with HIV/AIDS, their productivity deteriorates. Principals were clear about the inadequacy that they experience in responding to HIV/AIDS-related issues amongst teachers. They lack the training and management skills to develop long-term strategies to mitigate the impact of HIV/AIDS on teaching and learning. Teacher absenteeism is rife, causing drastically detrimental effects to teaching and learning programmes and posing serious challenges to principals, who are not equipped with the required information and resources. It was evident in this research study that infected teachers often fail to take responsibility or disclose their status; instead, they look to principals for solutions to their HIV/AIDS-related problems. / Educational Leadership and Management / D.

Les pays en développement et la brevetabilité des médicaments en matière de lutte contre le VIH/SIDA : étude de droit comparé sur les controverses actuelles concernant le rôle des brevets pharmaceutiques dans l'accès aux médicaments de traitement du VIH/SIDA des pays en voie de développement / Developing countries and patentability of drugs in the fight against HIV/AIDS : comparative law study on the current controversy about the role of pharmaceutical patents in the access to drugs for HIV/AIDS in developing countriesLoum-Neeser, N'deye fatou 25 September 2012 (has links)
Dans les pays en développement (PED), les problèmes engendrés par le VIH/SIDA et l’inaccessibilité des antirétroviraux (ARV) s’avèrent être la cause de ravages extrêmement préoccupants à tous les niveaux (démographique, politique, social et économique). Dans le cadre de l’Organisation mondiale du commerce (OMC), et notamment de l’Accord sur les aspects des droits de propriété intellectuelle qui touchent au commerce (« Accord sur les ADPIC »), un nombre croissant de PED ont ou sont en train d’intégrer un standard international de protection des brevets de produits et de procédés pharmaceutiques à leur législation nationale. Cette intégration a eu et continue de jouer un rôle majeur dans la problématique de l’accès aux médicaments dans les PED. Les conditions et les effets du régime de protection des innovations suscitent de vifs débats entre les partisans d’une protection accrue des brevets et les défenseurs de l’accès aux médicaments essentiels. Une des principales motivations de notre travail de recherche est de fournir une étude permettant de trouver des solutions à la fois favorables à l’amélioration de l’accès aux médicaments et à la préservation de l’innovation. Le problème complexe de l’accès aux médicaments ARV dans les PED est influencé par la pluridisciplinarité et l’interdépendance de nombreux facteurs. Le système des brevets ne constitue pas « l’unique » solution au problème. Toutefois, il doit être plus sérieusement considéré dans sa fonction d’équilibrage entre l’intérêt privé et l’intérêt collectif. C’est un outil juridique précieux pour le développement économique et technologique des PED et la réalisation de l’intérêt commun contre la pandémie. / In developing countries, problems brought about by HIV/AIDS and inaccessibility of antiretrovirals (ARVs) are proving to be the cause of serious damages at all levels (demographic, political, social and economic). Within the context of the World Trade Organization, and in particular the Agreement on Trade-Related Aspects of Intellectual Property Rights (“TRIPS Agreement”), a growing number of developing countries have integrated or are in the process of integrating into their national law an international standard of patent protection for pharmaceutical products and processes. Such integration continues to play a major role in the issue of access to medicines in developing countries. The conditions and effects of the protection regime respecting innovations give rise to heated debates between supporters of an increased patent protection and defenders of the access to essential medicines. One of the main motivations for our research is to provide a study that helps to find solutions that are both in favour of improving access to medicines and protecting innovation. The complex problem of access to ARV drugs in developing countries is influenced by the multidisciplinarity and interdependence of many factors. The patent system does not solve the problem on its own. However, it should be seriously considered in its function of balancing the private and collective interests. It is a valuable legal tool for the economic and technological development of the developing countries and to achieve the common interest against the pandemic.

Gemensamma Symboliska Beteenden Och Interaktioner Mellan Neanderthalare Och H. SapiensKarlsson, Julia January 2022 (has links)
The behaviours that the Neanderthals and Homo sapiens sapiens had in common could have made their interaction more advanced and deeper. Ever since Richard E. Green et al’s discovery in 2010 that a lot of the modern day population have inherited about 1-4 % of the genome from Neanderthals, the assumption that Neanderthals are primitive beings lacking advanced cognition has changed. For H. Sapiens to interbreed with Neanderthals one could argue that they could not have been that dissimilar. Since the modern day population inherited parts of the Neanderthals it could be very interesting to bring more insight into how their relationship and interaction would have looked in relation to H. Sapiens. In this thesis some behaviours will be analysed and compared that existed among them both. In this remark it will be about behaviors of a symbolic nature, indicating a more advanced thinking. These are the usage of personal ornaments, the burial practice, and lastly language and speech. The personal ornaments they used are in some instances very similar, but there is also variation in what they put value in as personal ornaments, later H. Sapiens put a lot of energy into making beads of different types, and Neanderthals having a focus on birds of prey. The burial practice is in general nothing that is too common among either of them during the middle palaeolithic or African Middle stone age. Before the upper palaeolithic there is not too much evidence indicating that they had a tradition of burying their dead. In cases they did bury their dead there is evidence of places with multiple burials, maybe working as grave centers. The anatomical capacities for speech existed among them both. When it comes to language it is harder to discern, since it does not fossilise, but since language is symbolic it could be argued that evidence of symbolism among them could indicate that they had language as well. In the discussion and conclusions it is argued that these common behaviours could have made it possible for a more advanced interaction and relationship between the two.

Virtual reality in tourism. Opportunity or pitfall? : Explorative case study of a place-based virtual reality experience of Mariebergsskogen / Virtuell verklighet i turismen. Möjlighet eller fallgrop? : En explorativ fallstudie om en platsbaserade virtuell verklighet upplevelse av MariebergsskogenKubitzek, Barbara January 2021 (has links)
To what extent can virtual reality be used to induce real-life tourism? This question becomes even more relevant in these covid-19 times. However, research on virtual reality concerning tourism has not engaged substantively with this question yet and thus this study seeks to address this question. This thesis is an explorative case study of the development of the prototype of a place-based virtual reality experience of Mariebergsskogen in Karlstad, Sweden. The purpose of this study is to investigate and show how a place-based virtual reality experience can add value to the experience and promotion of Mariebergsskogen. This thesis goes beyond ocularcentrism highlighting the involvement of senses, the whole body and emotions in experiencing a destination. How can a deeper emotional connection to a destination be evoked through virtual reality revealing the characteristics, uniqueness and rootedness of the place? A geomedia approach is taken that combines a sensitivity to place with media to arrive at a multi-dimensional view of Mariebergsskogen considering place representations, engagements and its roots to history. Place is conceptualized by recourse to Lefebvre’s (2011) spatial triad: lived, perceived and imagined that are in a dialectic relationship. The methodological model created has been informed by the project on place-based digital experiences (PDU) at the University of Karlstad in Sweden. Tourists are considered active agents in creating tourism destinations and this study emphasizes their engagement as co-creators in the prototype development process. A methodological model is proposed that combines a place analysis with workshops consisting of a user study and a co-creation workshop supplemented with insights from interviews with virtual reality developers and stakeholders from Region Värmland and Karlstad Municipality.
