La thèse évalue la pertinence doctrinale et scientifique de l'enseignement des Conférences épiscopales en matière démographique depuis 50 ans (1950-2000). Elle met en lumière leur approche méthodologique dans l'analyse de la problématique, la clarification des enjeux et la définition des repères éthiques qui devraient assurer le bien de la personne humaine et l'avenir de l'humanité. La re-lecture des interventions des évêques et des commissions épiscopales ad hoc a, notamment, permis de dégager trois points essentiels : la scientificité de leur approche méthodologique, les référents théologiques et magistériels de leur argumentation et les critères de discernement faisant du questionnement éthique le lieu géométrique du sens à donner à la question démographique. L'approche méthodologique est pertinente : les évêques et les Commissions épiscopales font preuve d'une grande maîtrise de la problématique démographique. L'appréciation des divers enjeux prend en considération la complexité des phénomènes démographiques en tant que tels et souligne l'importance de compter avec les multiples facteurs en cause. Elle récuse par ailleurs le simplisme de certaines analyses relevant de l'approche causale des phénomènes démographiques et montre, à la suite des papes Pie XII, Jean XXIII, Paul VI et Jean-Paul II, que la croissance démographique comme élément d'un système d'interactions multiples et complexes n'est pas la cause principale du sous-développement et de la dégradation de l'environnement. Les évêques et les Commissions épiscopales ad hoc reconnaissent cependant qu'un fort accroissement démographique peut exercer une pression importante sur les ressources et le processus de développement des pays déjà pauvres. Mais ils rejettent une solution exclusivement démographique axée sur la réduction du nombre des pauvres. Ils pensent que les politiques démographiques à mettre en œuvre devraient être intégrées dans une politique globale de développement socio-économique basée sur l'amélioration des conditions de vie. Cette unanimité de vue se fissure à propos de la planification familiale, une des variables les plus positivement corrélées avec les niveaux et les tendances de la fécondité. Le problème n'est pas au niveau de la définition du concept de " planification familiale " comme expression concrète de la parenté responsable telle qu'elle a été définie par le Concile Vatican II (Gaudium et spes, n° 50, § 2), mais au niveau du choix des moyens. Sont à exclure tous les moyens de régulation des naissances qui, d'une façon ou d'une autre, portent atteinte au droit à la vie de l'enfant à naître, à l'intégrité corporelle de la personne, à la responsabilité individuelle et à la dignité incessible de la personne comme " fin en soi ". Est-ce privilégier l'éthique sexuelle individuelle au détriment de l'éthique sociale que de le souligner ? La réponse est non, d'autant plus que l'on ne peut pas adopter n'importe quel moyen. A ce propos, le principe de responsabilité qui découle de la théologie de la création de l'homme créé " à l'image et à la ressemblance " de Dieu (Gn 1,26-27) et de la théologie de l'incarnation révèle non seulement les exigences éthiques qui définissent et encadrent l'impératif biblique " croissez et multipliez-vous " (Gn 1,28), mais aussi l'ensemble des valeurs qui oeuvrent en faveur d'une humanisation authentique de l'humanité. Ainsi, l'éthique démographique doit-elle tenir compte du bien de la personne humaine et de l'avenir de l'humanité. Elle doit se définir en rapport avec un certain nombre d'exigences : exigence de solidarité, de respect du droit à la vie et à la dignité de tout être humain. Sur ce point, s'il est vrai que la théo-logique des analyses trouve un certain écho dans la ratio-logique de l'éthique philosophique de responsabilité promue par E. Lévinas et H. Jonas, ces instances ecclésiales doivent trouver une expression audible et compréhensible de leur point de vue.

<p>Human trafficking is a widespread and growing crime in the world. Trafficking by its nature involves movement from one place to another and in most cases, it comprises crossing international borders. Although the estimation of victims of trafficking stretches to 2 450 000, the number of prosecutions is less than 5 000. This indicates the challenges faced by many countries in the investigation and prosecution of trafficking cases. Transnational human trafficking is committed in different places, making investigation and prosecution very complex. This paper examines how investigation and prosecution can be carried out when the criminal acts are committed in different countries. It also examines how the issue of jurisdiction is entertained. Furthermore, it addresses who can be termed as &ldquo / traffickers&rdquo / in dealing with human trafficking issues. Ethiopia is facing a big problem in fighting human trafficking. Like most countries, the issue of human trafficking is closely related to women. Ethiopia uses the criminal justice system as a tool to eradicate women trafficking. The investigation and prosecution of trafficking cases face many problems which have a direct impact on the country‟s efforts to overcome human trafficking. Thus, this research will contribute significantly by highlighting deficits in the criminal justice system as it deals with the investigation and prosecution of women trafficking issues and by making recommendations with regards to them.</p>

I denna studie beskriver jag problemet hur planering och zonering av destinationer för friluftsliv och ekoturism kan göras. Genom att utveckla och analysera teori och resultat abduktivt har analys och slutsats utvecklats med Kristianstad Vattenrike som utvalt studerat område. Kristianstad Vattenrike är ett av Sveriges fem biosfärområden och sträcker sig nästan över hela Kristianstad kommun med en mångfald av olika naturtyper. Som utnämnt biosfärområde ska man bidra till hållbar utveckling och utveckla området utefter ledorden bevara, utveckla och stödja och planera området i kärnområden, buffertzoner och utvecklingsområden. För att uppnå studiens syfte att abduktivt visa i teoretisk och analytisk växelverkan hur man kan planera och zonera en destination för friluftsliv och ekoturism så har jag valt att beskriva hur planering av friluftsliv kan göras, om zonering, om planering för ekoturism och rural turismutveckling. Dessa har utvecklats abduktivt med utvald kvalitativ metod för analys av en destination, Kristianstad Vattenrike, och hur det planeras i praktiken för eventuell zonering av friluftsliv och ekoturism enligt tre intervjuer och skriftliga källor om Kristianstad Vattenrike. I studiens resultat och analys analyseras tre frågeställningar för syftet: 1) Vilka förutsättningar för friluftsupplevelser och ekoturism erbjuder natur, landskap samt infrastruktur i Kristianstad Vattenrike?, 2) Hur planeras det för friluftsliv och ekoturism i Kristianstad Vattenrike? och 3) Varför ska zonering användas som medel för att planera hållbara destinationer för friluftsliv och ekoturism? Här beskrivs vilket brett utbud av naturtyper som erbjuds i ett friluftsliv som hela tiden utvecklas med behov och efterfrågan på området, men också med produktutveckling. Det beskrivs att de använt bl a plan för att utveckla badplatser inom Kristianstad Vattenrike som kan utvecklas generellt för friluftslivet. För ekoturism görs vissa näringslivssatsningar men inget som direkt lyckas inspirera till ett hållbart ansvarstagande för företag, men ett par uthålliga entreprenörer har lyckats med utveckling av säsonger för upplevelse av Vattenriket över året. Zonering som medel för planering av friluftsliv och ekoturism beskrivs och klargörs att det är en eftersatt modell i Sverige för planering av friluftsliv och ekoturism och även så i Kristianstad Vattenrike. Efter granskade resultat och analyser så dras slutsatser med studien att zonering behöver en svensk uttalad definition för att lättare kommuniceras och förstås för implementering som destinationer som Kristianstad Vattenrike skulle dra fördel av vid planering och zonering för friluftsliv och ekoturism.

La tesi es planteja en quina mesura l'estructura de la xarxa social existent en un districte turístic entre els diferents actors que la conformen, i la posició que aquests ocupen en la mateixa, afecta a la estacionalitat de la demanda hotelera del districte. S'assumeix que els fluxos d'informació i coneixement entre els actors del districte, i també entre aquests i d'altres actors externs determinaran la seva capacitat d'innovació, i per tant, la seva capacitat de creació de nous productes i ofertes turístiques capaces d'atraure turistes fora de la temporada alta. Així, es pretén analitzar si els hotels millor posicionats dins de l'estructura de relacions d'un districte turístic d'àmbit comarcal es corresponen amb els que presenten una millor estacionalitat en termes d'allargament de la temporada, de mesos d'obertura i de millora de l'ocupació en els dos darrers períodes. Addicionalment, s'analitza en quina mesura els segments de mercat turístic als que els hotels dirigeixen els seus esforços expliquen les diferencies d'estacionalitat entre ells. / The thesis analyses how the structure of a social network and the position held by actors within it affect the seasonality and hotel demand within a specific tourist district.It assumes that the information and knowledge shared between the actors in the area, and also between these and other external actors, determines their capacity for innovation, and therefore their capacity for creating new products and tourist offers capable of attracting tourists outside the high season. Thus, I have analysed if the hotels which are better connected within a specific tourist district correspond to those which have less seasonality in terms of the following: a longer tourist season (i.e. open more months of the year); a higher occupancy rate in the shoulder seasons; and an improvement in seasonality over time. In addition, the thesis analyses the degree to which the segments of the tourist market targeted by the hotel industry explain the differences in seasonality between them.

Living in an increasingly networked world, with an abundant number of services available to consumers, the consumer electronics market is enjoying a boom. The average consumer in the developed world may own several networked devices such as games consoles, mobile phones, PDAs, laptops and desktops, wireless picture frames and printers to name but a few. With this growing number of networked devices comes a growing demand for services, defined here as functions requested by a client and provided by a networked node. For example, a client may wish to download and share music or pictures, find and use printer services, or lookup information (e.g. train times, cinema bookings). It is notable that a significant proportion of networked devices are now mobile. Mobile devices introduce a new dynamic to the service discovery problem, such as lower battery and processing power and more expensive bandwidth. Device owners expect to access services not only in their immediate proximity, but further afield (e.g. in their homes and offices). Solving these problems is the focus of this research. This Thesis offers two alternative approaches to service discovery in Wide Area Networks (WANs). Firstly, a unique combination of the Session Initiation Protocol (SIP) and the OSGi middleware technology is presented to provide both mobility and service discovery capability in WANs. Through experimentation, this technique is shown to be successful where the number of operating domains is small, but it does not scale well. To address the issue of scalability, this Thesis proposes the use of Peer-to-Peer (P2P) service overlays as a medium for service discovery in WANs. To confirm that P2P overlays can in fact support service discovery, a technique to utilise the Distributed Hash Table (DHT) functionality of distributed systems is used to store and retrieve service advertisements. Through simulation, this is shown to be both a scalable and a flexible service discovery technique. However, the problems associated with P2P networks with respect to efficiency are well documented. In a novel approach to reduce messaging costs in P2P networks, multi-destination multicast is used. Two well known P2P overlays are extended using the Explicit Multi-Unicast (XCAST) protocol. The resulting analysis of this extension provides a strong argument for multiple P2P maintenance algorithms co-existing in a single P2P overlay to provide adaptable performance. A novel multi-tier P2P overlay system is presented, which is tailored for service rich mobile devices and which provides an efficient platform for service discovery.

With numerous artists coming to South Africa, the event industry is becoming congested with competition. This makes the production of a memorable visitor experience to events particularly challenging for the management of the event. Various aspects are required to occur when managing an event, and these contribute to the success and memorable experience of visitors. These aspects can either be controlled or uncontrolled by management. To ensure a successful event and memorable experience for visitors, event managers have to consider all of the various aspects that can be controlled within the event organisation when hosting a major music event. It is therefore important for management to ensure that the controllable key management aspects, also referred to as Critical Success Factors (CSFs), are implemented effectively and efficiently to ensure a memorable visitor experience. However, even though these management aspects (CSFs) may be familiar to event managers, the significance of what visitors regard as important concerning those aspects that would ensure a memorable visitor experience is, as yet, undefined. In addition, according to available literature, CSFs differ between the different events and different tourism organisations. Thus, CSFs identified at one event to ensure the successful management of a memorable visitor experience cannot be used at other events. Hosting major music events at various locations can be even more challenging as visitors attending major music events at different locations are a non-homogeneous market and so regard different aspects in different lights. Therefore, it is evident that the CSFs identified with regard to what visitors at one venue will consider as important will differ from those regarded as important at another venue, even when it is the same performer at each venue. Thus, it became critical to seek answers to the questions of what visitors to a major music event regarded as important CSFs and how did the importance of these CSFs differ between location and location? Therefore, the purpose of this study became the determination of the CSFs for managing the visitor experience at major music events in South Africa. The year 2011 was the first time that world-famous Neil Diamond had performed in South Africa. Neil Diamond performed four concerts at different locations (Johannesburg’s FNB stadium, Durban’s Moses Mabhida Stadium, Cape Town’s Greenpoint Stadium and at Port Elizabeth’s Nelson Mandela Stadium). This was the first time major music events had been held at these venues where one performing artist performed at all four different locations (cities). Thus, this event was the ideal opportunity to investigate. In order to realise the goal of the research, surveys were conducted at the four Neil Diamond concerts held, respectively, in Johannesburg (1 April, 2011), Durban (5 April, 2011), Port Elizabeth (8 April, 2011) and Cape Town (11 April, 2011) where, altogether, 1820 questionnaires were administered. The purpose of the first article was to determine what visitors at a major musical event regarded as critical management aspects, or as critical success factors (CSFs), for a memorable and satisfactory visitor experience. This was to aid major music event managers with information they could use to improve and ensure memorable visitor experiences in the future. A factor analysis was performed to determine the CSFs. Six factors were revealed, being General Management; Souvenirs; Marketing; Venue and Technical aspects; Accessibility and Parking; and Amenities and Catering. General Management, Venue and Technical aspects and Marketing were regarded as the most important CSFs for visitors to a major music event. It was subsequently confirmed that CSFs differed from one event to another. Thus it became clear that one set of CSFs cannot be used across each venue for events. By determining the CSFs, and through successfully managing these factors, major music events will ensure the retention of long term visitor goodwill, and so will remain competitive and sustainable. Neil Diamond presented four concerts at four different locations, The purpose of the second article was to determine the impact that location makes to the visitor experience at a major music event. Two-way frequency tables and Chi-square tests as well as ANOVAS and Turkey’s multiple comparisons were used to determine the differences between the four locations. Statistically significant differences were found, based on demographic, behavioural variables and motivational factors. Determining the effects these differences have provided major music event managers with superior knowledge in order to develop and manage future concerts at the differing destinations and locations. This research also help management to create a memorable visitor experience and so foster the promotion of future events more effectively to the target audiences, as well as potential sponsors. This specificity can also enhance bid documents for organisations and locations aiming at hosting major music events. This research revealed six critical success factors at a major music event. These CSFs can be used to enhance the visitor experience. However, it was also found that one set of CSFs cannot be used for every event as different locations regard different CSFs as being more important than others. Since major music events are often held at more than one location, it becomes critical to differentiate each location as the visitors to the various locations cannot be seen as homogeneous and so will have different needs and expectations. Thorough and informed knowledge of what is required for visitor satisfaction will not only ensure an improved event, but will enhance the visitor experience at such an event. This was the first time research was performed at major music events in South Africa that revealed the profile, motives, CSFs and spending behaviour of visitors to these events. Research not only provided information concerning the CSFs needed to manage the visitor experience at a major music event, but also provided an overall perspective of what visitors regard as important for a memorable visitor experience at four different geographic destinations hosting the same artist. This research contributes to the literature concerning the management of major music events and concerning the creation of memorable visitor experiences at these events. / Thesis (MA (Tourism Management))--North-West University, Potchefstroom Campus, 2012

xiv, 141 p. ： ill. / This study examines how health care administrators perceive Spanish-speaking immigrant growth in a city with little to no history of attracting immigrants but recently experiencing tremendous growth. Different communities are finding a need to adjust various institutions, organizations, and policies to meet the needs of newer groups, which often arrive in communities ill-equipped to deal with the structural and social changes necessary to serve them. This study investigates the ways one health care system's administrators frame the institution's role and response as the surrounding city is transformed into a new destination city. Their responses complicate existing understandings of how people discuss newly settled immigrant groups in an era of racial colorblindness, as this colorblindness often cloaks underlying racial prejudice. Administrators who expressed egalitarian understandings professionally often shifted to rigid racial boundaries in their private lives. Moving the color line based on the arena of conversation challenges existing theories, which mark racial hierarchies as static lines demarcating divisions between two or three groups. Finally, administrators link the needs of Spanish-speaking patients to the health system's Mission Department, reinforcing cultural representations of this particular group as indigent and outside the mainstream services offered by the health care system. / Committee in charge: Dr. Mia Tuan， Co-Chair； Dr. Jocelyn Hollander， Co-Chair； Dr. Aliya Saperstein， Member； Dr. Susan Hardwick， Member

Um dos principais problemas enfrentados atualmente pelo Poder Público e pela sociedade é a destinação adequada de resíduos sólidos. O objetivo principal deste trabalho é avaliar a gestão dos resíduos sólidos urbanos (RSU) implantada no Rio Grande do Sul e verificar a existência de melhorias após a promulgação da Política Nacional de Resíduos Sólidos (PNRS). Este trabalho ainda apresenta o gerenciamento de resíduos sólidos no Brasil e na Europa, as formas de tratamento e disposição final dos resíduos sólidos urbanos, os tipos de tratamento de lixiviados existentes, identifica alternativa de reuso do lixiviado após tratamento, analisa os tratamentos de lixiviado utilizados em Aterros Sanitários localizados no estado do Rio Grande do Sul (RS) e em Portugal, o cumprimento das metas estipuladas para RSU nos Planos de Resíduos Sólidos e identifica e compara a legislação existente em Portugal e no Brasil que regulamenta a instalação e operação dos Aterros Sanitários. Para a elaboração foram analisados dados de destinação de RSU no Brasil, com especial ênfase ao estado do Rio Grande do Sul, e em Portugal. Através dos dados obtidos verifica-se que houve melhorias na destinação final dos RSU no Brasil após a homologação da PNRS, por exemplo houve um aumento de 138% de municípios que implantaram a coleta seletiva após a PNRS. Verificou-se que a forma mais utilizada de destinação final dos RSU no país é por meio de aterro sanitário, porém havendo ainda disposição inadequada por meio de aterros controlados e lixões. No RS em 2015, observou-se que houve uma redução na disposição final adequada em comparação ao ano de 2014, devido à má operação dos aterros sanitários, porém foi atingida a Meta 1 do Plano Nacional de Resíduos Sólidos (PLANARES), uma vez que em 2015 não havia lixões em operação no RS. Foi possível observar que no RS a maioria das áreas classificadas como inadequadas são administradas pelos próprios municípios, isto se dá devido à falta de recurso financeiro para gerenciar e operar um aterro sanitário. Com relação ao tratamento de lixiviado gerado nos aterros sanitários do RS, verificou-se que estes não possuem implantado um sistema eficaz e acredita-se que somente um tratamento combinado, apresentando tratamento avançado, seja a forma mais adequada para tratar este efluente, devido à grande variabilidade de características e complexidade do lixiviado. Fazendo uma comparação da legislação referente à gestão de resíduos no Brasil e em Portugal, observa-se que em 1996 foi aprovado o Plano Estratégico Setorial dos Resíduos Sólidos Urbanos (PERSU) em Portugal, que promoveu uma grande alteração na gestão de RSU, havendo grandes investimentos em infraestrutura visando atender as metas do PERSU. Já no Brasil somente em 2010 foi proposta esta alteração por meio da PNRS, e é possível observar que não houve o atendimento das metas estipuladas nos Planos Nacionais e Estadual, no caso do RS, devido à falta de conscientização do Poder Público e investimentos nesta área, de forma a promover uma destinação final adequada para os RSU gerados no país. / One of the main problems currently faced by the Government and the society is the appropriate destination of solid waste. The main objective of this study is to evaluate the management of municipal solid waste (MSW) introduced in Rio Grande do Sul and to verify possible improvements achieved after the promulgation of the National Solid Waste Policy (NSWP). This paper also describes the management of solid waste in Brazil and Europe, the way of treatment and final disposal of municipal solid waste, the existing leachate treatment process, identifies leachate reuse alternatives, analyzes the leachate treatment operations used in landfills located in the State of Rio Grande do Sul (RS) and in Portugal, the achievement of goal set for MSW in Solid Waste Plans and identifies and compares the legislation existing in Portugal and Brazil which regulates the installation and operation of Landfills. For the work accomplishment, data of the MSW disposal in Brazil, with special emphasis on the State of Rio Grande do Sul, and Portugal were analyzed. Through the data obtained it appears that there were improvements in the final disposal of MSW in Brazil after the approval of NSWP, for example an increase of 138% of municipalities that have implemented selective collection after NSWP. It was found that the most used form of final disposal of MSW in the country is through landfill, but there is still inadequate disposal in controlled landfills and dumps. In RS in 2015, it was observed that there was a reduction in the number of adequate final disposal sites, compared to 2014, due to wrong operation of landfills. Nevertheless, Goal 1 of the National Plan of the Solid Waste (NPSW) was achieved, since in 2015 there was no dumps operating in RS. It was observed that in RS most of the areas classified as inadequate are administered by the municipalities themselves. This, is due to lack of financial resources to manage and operate a landfill. Regarding the treatment of leachate generated in landfills of RS, it was found that these have not implemented an effective system and it is believed that only a combined treatment, with advanced treatment, will be the best way to treat this effluent due to the large variability of characteristics and complexity of the leachate. Making a comparison of the legislation on waste management in Brazil and in Portugal, it is observed that in 1996 the Sector Strategic Plan for Municipal Solid Waste (SSPMSW) was approved in Portugal, promoting a major change in the MSW management, with large investments in infrastructure to deal the goals of the SSPMSW. On the other hand, in Brazil only in 2010 this change was proposed by NSWP. It is possible to observe that goals set in the National and State Plans were not met, in the case of RS, due to lack of awareness of the government and investments in this area in order to promote an appropriate final destination for the MSW generated in the country.
