A group resilience-promoting programme for individuals whose partners have acquired a spinal cord injury

Steyn, Yolinda January 2015 (has links)
Spinal cord injury (SCI) is an acquired physical disability through traumatic injuries such as car accidents and shooting incidents, and non-traumatic injury such as a tumour on the spinal cord, amongst others. Unlike other parts of the body, the spinal cord does not have the ability to repair itself if it is damaged. Consequently, a person who has acquired an SCI will have a physical disability and will be either a paraplegic – paralysis of the lower part of the body, including the legs, or a quadriplegic, which is paralysis of all four limbs. Acquiring a spinal cord injury (SCI) has devastating long-term negative outcomes for the injured person as well as his/her cohabiting partner on a physical, psychological, psychosocial and socio-economical level. Exposure to such prolonged adversity and resulting negative outcomes calls for resilience, namely the ability to positively adapt despite the adversity being exposed to. Not all individuals have the natural ability to “bounce back”, and consequently resilience promotion is imperative. In South Africa, the focus of service delivery in rehabilitation centres is mainly centred on the injured person and consequently the well-being of the spinal cord injured person’s partner (SCIPP) is neglected. Little information is available on resilience-promoting programmes for SCIPPs; thus the main aim of this study was to design and develop a group resilience-promoting programme (GRPP) for SCIPPs. The researcher mainly followed a qualitative research approach and included a small quantitative component. In the context of applied research, an intervention research model comprising six phases was employed. Phase 1, Problem analysis and project planning, was reported on in section A. Manuscript 1 reports on phase 2 (information gathering and synthesis), and consists of a qualitative research synthesis, and mainly aimed at organizing and synthesizing previous research on resilience-promoting processes in order to inform the design and development of a group resilience-promoting programme (GRPP) for SCIPPs. After a systematic review and quality appraisal a total of 74 papers were selected to be quality appraised after abstracts and titles were assessed for relevance. Twenty-one studies were included and synthesized where after an outline for the content of a GRPP for SCIPPs was formulated. Conclusions and recommendations highlight that the formulated GRPP for SCIPPs needs to be further developed into an intervention that could be implemented with SCIPPs. As such, the researcher therefore proceeded with the study (see manuscript 2), aiming in developing small-group programme content and activities (using knowledge gathered from pre-existing interventions; resilience literature; consultations with experts; people living with spinal cord injury (SCI) and personal experience) to promote resilience in SCIPPs. By means of purposive sampling six advisory panel members from a diverse background were interviewed before and after the pilot study with two SCIPPs and one observer to contribute towards the further development of the GRPP for SCIPPs. A six-session GRPP for SCIPPs was formulated, including the following: (1) Information on SCI and resilience; (2) Help SCIPPs understand that their reactions to/emotions regarding these huge changes are normal; (3) Caretaking and support; (4) My dual role; (5) Own caretaking by SCIPPs; and (6) Termination and way forward. The newly developed GRPP for SCIPPs however had to be formally evaluated. Recommendations were made by professionals in the field that the GRPP for SCIPPs should first be subjected to peer review prior to implementing it with the target population. Therefore in manuscript 3 (reporting on phase 5 – evaluation ) the evaluation purpose was to subject the GRPP for SCIPPs to peer review by means of an empirical study with professional role-players (social workers and psychologists) in the field of spinal cord injury, prior to exhibiting it to the target population. The six group sessions were presented to professional role-players (n=12) working within the field of SCI during two 2-day workshops, whereby they were requested to evaluate the content and procedural elements of the GRPP for SCIPPs mainly by means of qualitative research, with a small numerical (quantitative) component. Thematic content analysis and basic descriptive statistics were employed. Overall positive feedback regarding the newly developed intervention was received, with suggested adjustments that needed to be made to the GRPP for SCIPPs prior to formal evaluation with the target group. The GRPP for SCIPPs will further be subjected to expert review in other provinces in South Africa, as the current participants were all from Gauteng. Furthermore, postgraduate students will be recruited to test the programme with the target-population in South Africa for possible further improvement and suggestions, as well as possible expansion to adjust this intervention to meet the needs of male SCIPPs; SCIPs themselves; children of a parent/s living with SCI; and also for post-injury cohabiting relationships, as this intervention might be a starting point for above-mentioned research-opportunities.

Human Behaviour in Social-Ecological Systems : Insights from economic experiments and agent-based modelling

Schill, Caroline January 2017 (has links)
Progress towards sustainability requires changes in our individual and collective behaviour. Yet, our fundamental understanding of behaviour in relation to environmental change remains severely limited. In particular, little attention has been given to how individual and collective behaviours respond to, and are shaped by, non-linear environmental change (such as ‘regime shifts’) and its inherent uncertainties. The thesis makes two main contributions to the literature: 1) it provides one of the first accounts of human behaviour and collective action in relation to ecological regime shifts and associated uncertainties; and 2) extends the incipient behavioural common-pool resource literature that acknowledges social-ecological dynamics and ecological complexity. The overarching aim of this thesis is to further advance an empirically grounded understanding of human behaviour in social-ecological systems. In particular, the thesis attempts to unravel critical social-ecological factors and mechanisms for the sustainability of common-pool resources. This is especially relevant for contexts in which livelihoods can be more directly threatened by regime shifts. The following methods are applied: behavioural economic experiments in the lab (with students; Papers I and II) and in the field (with small-scale fishers from four different communities in the Colombian Caribbean; Paper III), and agent-based modelling empirically informed by a subset of the lab experiments (Paper IV). Paper I tests the effect of an endogenously driven regime shift on the emergence of cooperation and sustainable resource use. Paper II tests the effect of different risk levels of such a regime shift. The regime shift in both papers has negative consequences for the productivity of the shared resource. Paper III assesses the effect of different degrees of uncertainty about a climate-induced threshold in stock dynamics on the exploitation patterns; as well as the role of social and ecological local context. Paper IV explores critical individual-level factors and processes affecting the simultaneous emergence of collective action and sustainable resource use. Results cumulatively suggest that existing scientific knowledge indicating the potential for ecological regime shifts should be communicated to affected local communities, including the remaining uncertainties, as this information can encourage collective action for sustainable resource use. Results also highlight the critical role of ecological knowledge, knowledge-sharing, perceived ecological uncertainties, and the role local contexts play for sustainable outcomes. This thesis enriches the literature on social-ecological systems by demonstrating how a behavioural experimental approach can contribute new insights relevant for sustainability. Overall, these insights indicate that, given the opportunity and the willingness of people to come together, share knowledge, exchange ideas, and build trust, potential ecological crises can encourage collective action, and uncertainties can be turned into opportunities for dealing with change in constructive ways. This provides a hopeful outlook in the face of escalating environmental change and inherent uncertainties. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 3: Manuscript.</p>

Cogestion des ressources naturelles : une approche structurale pour quantifier la contribution des réseaux d'acteurs à la résilience des systèmes socio-écologiques

Gonzalès, Rodolphe 03 1900 (has links)
Alors que les activités anthropiques font basculer de nombreux écosystèmes vers des régimes fonctionnels différents, la résilience des systèmes socio-écologiques devient un problème pressant. Des acteurs locaux, impliqués dans une grande diversité de groupes — allant d’initiatives locales et indépendantes à de grandes institutions formelles — peuvent agir sur ces questions en collaborant au développement, à la promotion ou à l’implantation de pratiques plus en accord avec ce que l’environnement peut fournir. De ces collaborations répétées émergent des réseaux complexes, et il a été montré que la topologie de ces réseaux peut améliorer la résilience des systèmes socio-écologiques (SSÉ) auxquels ils participent. La topologie des réseaux d’acteurs favorisant la résilience de leur SSÉ est caractérisée par une combinaison de plusieurs facteurs : la structure doit être modulaire afin d’aider les différents groupes à développer et proposer des solutions à la fois plus innovantes (en réduisant l’homogénéisation du réseau), et plus proches de leurs intérêts propres ; elle doit être bien connectée et facilement synchronisable afin de faciliter les consensus, d’augmenter le capital social, ainsi que la capacité d’apprentissage ; enfin, elle doit être robuste, afin d’éviter que les deux premières caractéristiques ne souffrent du retrait volontaire ou de la mise à l’écart de certains acteurs. Ces caractéristiques, qui sont relativement intuitives à la fois conceptuellement et dans leur application mathématique, sont souvent employées séparément pour analyser les qualités structurales de réseaux d’acteurs empiriques. Cependant, certaines sont, par nature, incompatibles entre elles. Par exemple, le degré de modularité d’un réseau ne peut pas augmenter au même rythme que sa connectivité, et cette dernière ne peut pas être améliorée tout en améliorant sa robustesse. Cet obstacle rend difficile la création d’une mesure globale, car le niveau auquel le réseau des acteurs contribue à améliorer la résilience du SSÉ ne peut pas être la simple addition des caractéristiques citées, mais plutôt le résultat d’un compromis subtil entre celles-ci. Le travail présenté ici a pour objectifs (1), d’explorer les compromis entre ces caractéristiques ; (2) de proposer une mesure du degré auquel un réseau empirique d’acteurs contribue à la résilience de son SSÉ ; et (3) d’analyser un réseau empirique à la lumière, entre autres, de ces qualités structurales. Cette thèse s’articule autour d’une introduction et de quatre chapitres numérotés de 2 à 5. Le chapitre 2 est une revue de la littérature sur la résilience des SSÉ. Il identifie une série de caractéristiques structurales (ainsi que les mesures de réseaux qui leur correspondent) liées à l’amélioration de la résilience dans les SSÉ. Le chapitre 3 est une étude de cas sur la péninsule d’Eyre, une région rurale d’Australie-Méridionale où l’occupation du sol, ainsi que les changements climatiques, contribuent à l’érosion de la biodiversité. Pour cette étude de cas, des travaux de terrain ont été effectués en 2010 et 2011 durant lesquels une série d’entrevues a permis de créer une liste des acteurs de la cogestion de la biodiversité sur la péninsule. Les données collectées ont été utilisées pour le développement d’un questionnaire en ligne permettant de documenter les interactions entre ces acteurs. Ces deux étapes ont permis la reconstitution d’un réseau pondéré et dirigé de 129 acteurs individuels et 1180 relations. Le chapitre 4 décrit une méthodologie pour mesurer le degré auquel un réseau d’acteurs participe à la résilience du SSÉ dans lequel il est inclus. La méthode s’articule en deux étapes : premièrement, un algorithme d’optimisation (recuit simulé) est utilisé pour fabriquer un archétype semi-aléatoire correspondant à un compromis entre des niveaux élevés de modularité, de connectivité et de robustesse. Deuxièmement, un réseau empirique (comme celui de la péninsule d’Eyre) est comparé au réseau archétypique par le biais d’une mesure de distance structurelle. Plus la distance est courte, et plus le réseau empirique est proche de sa configuration optimale. La cinquième et dernier chapitre est une amélioration de l’algorithme de recuit simulé utilisé dans le chapitre 4. Comme il est d’usage pour ce genre d’algorithmes, le recuit simulé utilisé projetait les dimensions du problème multiobjectif dans une seule dimension (sous la forme d’une moyenne pondérée). Si cette technique donne de très bons résultats ponctuellement, elle n’autorise la production que d’une seule solution parmi la multitude de compromis possibles entre les différents objectifs. Afin de mieux explorer ces compromis, nous proposons un algorithme de recuit simulé multiobjectifs qui, plutôt que d’optimiser une seule solution, optimise une surface multidimensionnelle de solutions. Cette étude, qui se concentre sur la partie sociale des systèmes socio-écologiques, améliore notre compréhension des structures actorielles qui contribuent à la résilience des SSÉ. Elle montre que si certaines caractéristiques profitables à la résilience sont incompatibles (modularité et connectivité, ou — dans une moindre mesure — connectivité et robustesse), d’autres sont plus facilement conciliables (connectivité et synchronisabilité, ou — dans une moindre mesure — modularité et robustesse). Elle fournit également une méthode intuitive pour mesurer quantitativement des réseaux d’acteurs empiriques, et ouvre ainsi la voie vers, par exemple, des comparaisons d’études de cas, ou des suivis — dans le temps — de réseaux d’acteurs. De plus, cette thèse inclut une étude de cas qui fait la lumière sur l’importance de certains groupes institutionnels pour la coordination des collaborations et des échanges de connaissances entre des acteurs aux intérêts potentiellement divergents. / As anthropic activities are slowly pushing many ecosystems towards their functional tipping points, social-ecological resilience has become a pressing concern. Local stakeholders, acting within a diversity of groups — from grassroots organizations to higher-scale institutional structures — may act on these issues and collaborate to develop, promote, and implement more sustainable practices. From these repeated collaborations emerge complex networks, the topologies of which have been shown to either enhance or hinder social-ecological systems’ (SES) resilience. The main topological characteristics of a stakeholder network enhancing SES’s resilience include a combination of: a highly modular community structure, which helps groups of stakeholders develop and propose solutions both more innovative (by reducing knowledge homogeneity in the network), and close to their interest and values; high connectivity and synchronizability, in order to improve consensus building, social capital and learning capacity; and high robustness so as to prevent the first two characteristics from sharply decreasing if some stakeholders were to leave the network. These characteristics are straight-forward both in concept and in their mathematical implementation, and have often been used separately to discuss the structural qualities of stakeholder networks in case studies. However, some of these topological features inherently contradict each other. For example, modularity is in direct conflict with connectivity, which is in conflict with a network’s robustness. This issue makes the creation of a more global measure difficult, as the level to which stakeholders contribute to enhancing SES’s resilience cannot simply be a summation of these features, but instead needs to be the outcome of a delicate trade-off between them. The present study aims to: (1) explore the trade-offs at work between these structural features; (2) produce a measure of how well-suited empirical stakeholder networks are to enhancing the resilience of their SES; and (3) thoroughly analyze an empirical stakeholder network in the context, among other things, of its resilience-enhancing qualities. This dissertation is organized in four parts. The first part (Chapter 2) is a review of the literature on SES resilience. It identifies a series of structural features (as well as their corresponding network metrics) associated with resilience-enhancement in SES. The second part (Chapter 3) is a case study on the Eyre Peninsula (EP), a rural region of South Australia where land-use, as well as climate change, contribute to biodiversity erosion. For this case study, field work was conducted in 2010 and 2011, during which time a series of face-to-face interviews was conducted to populate a list of individuals — and groups of individuals — holding a stake in biodiversity conservation on the EP. The data was thereafter used to develop an online questionnaire documenting interactions between these stakeholders. The two steps led to produce a weighted, directed network of 129 stakeholders interacting through 1180 collaboration links. The third part (Chapter 4) describes a methodology to measure the level to which stakeholder networks contribute to resilience-building in SES. The method is articulated in two steps: (i) an optimization algorithm (simulated annealing — SA —) is used to craft a semi-random archetypal network which scores high in one compromise of modularity, connectivity, synchronizability, and robustness, and (ii) an empirical stakeholder networks (such as our EP network) is compared to the archetypal network through a measure of structural distance. The shorter the distance, the closer the empirical network is to its ideal configuration. The fourth and last part of the dissertation research (Chapter 5) is an improvement on the simulated annealing used in Chapter 4. As is frequently done for this kind of optimization technique, the SA used in Chapter 4 projected the four dimensions of the multi-objective problem into one (as a weighted average). While performing well, this only resolves one of the possible trade-offs between the objectives. To better explore the trade-offs at work in this optimization problem, a true multi-objective simulated annealing (MOSA) is proposed where, instead of optimizing one solution, the algorithm optimizes a multidimensional surface of solutions scoring better than the others in a least one of the objectives. This study, which focuses on the social part of SESs, improves our understanding of the stakeholder collaboration structures which, theoretically, best contribute to resilient SESs. It shows that while some resilience-enhancing topological characteristics are in conflict (modularity vs. connectivity, and connectivity vs. robustness to a lesser extent) others can be easily reconciled (connectivity vs. synchronizability, and, less-so, modularity vs. robustness). It also provides an intuitive method to quantitatively assess empirical stakeholder networks, which opens the way to comparisons between case studies, or monitoring of stakeholder network evolution through time. Additionally, this thesis provides a case study which highlights the importance of a key institutional group in coordinating collaborations and information exchanges among other stakeholders of potentially diverging interests and values.

Perceptions about Sexually Transmitted Diseases in Akwa Ibom State of Nigeria: A Qualitative Study of Young Adults Age 18-24

Archibong, Mfon Archibong 01 January 2016 (has links)
Despite the ongoing investments in programs to increase sexual health awareness among young adults globally, many youths remain vulnerable to sexually transmitted diseases (STDs). Two-thirds of all STDs occur among youths engaging in high-risk sexual behaviors, which put young adults at higher risk of STDs and can result in serious consequences including infertility. Additionally, the social consequences of STD affect families and communities. While a need exists for increased public awareness of STDs among young adults, extant intervention and prevention activities should be informed by a cultural perspective, including the integration of community and government roles. The purpose of this social ecological study was to investigate the perceptions of STDs and the potential factors responsible for the increased frequency of STDs based on the lived experiences of 20 young adults with STDs in Akwa Ibom State, Nigeria. Through a qualitative approach using a phenomenological research design, this study employed semi-structured interviews, and the resultant data were analyzed and coded. The findings indicated that college-aged students increasingly engaged in sexually risky behavior with multiple sexual partners for financial gain and power. Additionally, while institutions promoted abstinence as an effective strategy to reduce STD infections, the findings indicated a strong relationship between the phenomenon and individual interconnectedness with the larger society. Because the sexual behavior of young adults in Akwa Ibom State, Nigeria, is influenced at multiple ecological levels, effective and sustaining culturally appropriate STD interventions must involve the larger society including young adults in all stages of intervention development and implementation.

Enhancing social-ecological resilience in the Colorado River Basin

Eidem, Nathan T., 1978- 08 March 2012 (has links)
This research presents the Colorado River basin as a social-ecological system. Utilizing event data on cooperative and conflictive interactions over fresh water, the system is decomposed to look for evidence of outcomes of resilience enhancement. The Animas-La Plata Project in the upper San Juan basin is presented as a case study, and qualitative methods are used to analyze interactions that led to its construction in order to assess social-ecological outcomes. In the upper San Juan basin, cooperative interactions over fresh water outnumbered conflictive ones. Interactions over water rights and infrastructure were most common, and the most cooperative interactions focused on these issue types. Many of these interactions focused on the Animas-La Plata Project compromise, which ultimately enhances social-ecological resilience in the Colorado River basin. / Graduation date: 2012

A river loved : facilitating cooperative negotiation of transboundary water resource management in the Columbia River Basin through documentary film

Watson, Julie Elkins 25 April 2012 (has links)
In transboundary water resources policy and management situations, such as the governance of the Columbia River Basin, complex social, ecological, and economic factors seem to be in irreconcilable competition with one another. However, cooperative negotiation provides an outlet for entities and stakeholders to "expand the pie" and develop creative alternatives for integrated, resilient management. To achieve these goals, it is critical that stakeholders have meaningful dialogue that goes beyond positions to identify the underlying values and interests in the basin. Furthermore, parties must develop a shared understanding of the substantive complexities of the social-ecological system. Collaborative learning allows participants to meet both of these objectives at once, and facilitators can spark collaboration through carefully planned interventions. The goal of this study was to test a carefully crafted "facilitative" documentary film as a facilitation tool to promote dialogue, understanding, and creative scenario development amongst parties. The study has three main components: 1) the resilience and learning analysis of the case study (the Columbia River Treaty) policy situation, 2) the creation of a facilitative film featuring interviews with diverse stakeholders in the basin, and 3) the qualitative and quantitative assessment of the effects of the film in the cooperative negotiation process. The film, A River Loved: A film about the Columbia River and the people invested in its future, premiered at the Universities Consortium Symposium on Columbia River Governance- an informal forum for dialogue held in Kimberley, British Columbia in October 2011. I measured participants' reactions to the film and found substantial support for my hypotheses, concluding that interventions such as facilitative documentary film have great potential to transform complex, multi-stakeholder social-ecological policy situations. / Graduation date: 2012

Resilience of large river basins : applying social-ecological systems theory, conflict management, and collaboration on the Mekong and Columbia Basins

MacQuarrie, Patrick R. 11 July 2012 (has links)
River basins provide essential services for both humans and ecosystems. Understanding the connections between ecosystems and society and their function has been at the heart of resilience studies and has become an increasing important endeavor in research and practice. In this dissertation, I define basin resilience as a river basin system's capacity to absorb, manage, and adapt to biophysical, social-economic, and political changes (or stressors) while still maintaining its essential structure, feedbacks, and functional integrity. I address the question of resilience, scale, and development in the Mekong and Columbia River Basins. This dissertation answers the following questions: 1) is systems theory an appropriate model to evaluate basin resilience, 2) is the Mekong Basin resilient, 3) are the Mekong and Columbia River Basins resilient across multiple scales, 4) can conflict management and collaborative learning enhance resilience, 5) can a resilience framework be used for basin comparisons, and 6) what lessons can the Mekong basin take from rapid development in the Columbia basin? In Chapter 2, I create and apply a social-ecological systems (SES) model of the Mekong River Basin to assess resilience at sub-basin (provincial), watershed (national), and basin (regional) scales. Feedbacks, thresholds, vulnerability, and adaptive capacity are determined and used as inputs into an overall basin resilience assessment. Drawing upon field work done in the Mekong Basin, Chapter 3 uses Conflict Management and Collaborative Learning processes to address resilience weaknesses across multiple scales in the Mekong Basin. Chapter 4 uses the basin resilience framework to compare the Mekong and Columbia Basins against physical characteristics, development rate, conflict and cooperation, and institutional responses to development projects. In this dissertation I find the Mekong has medium-low basin resilience and that scale is a critical determinant in basin resilience assessments. I find that in this study, vulnerability is inversely proportional to resilience, and low resilience at one scale, for example fisheries in the Tonle Sap Lake in Cambodia, decreases resilience for the entire basin. I find that Cambodia and Lao PDR are the least resilience and Thailand the most resilient countries in the Mekong Basin ��� Thailand more resilient in some sectors than the Mekong River Commission (MRC). I find that the MRC's conflict management strategy is hampered by a restrictive mandate and weakness in capacity building at tributary and national scales but that Collaborative Learning processes are effective in enhancing resilience at the sub-basin scale. Finally, I demonstrate through the basin comparison that the Mekong has a highly resilient biophysical system and traditionally a resilient institutional system however, the proposed rate of development is unsustainable with trends indicating a significant erosion of resilience. I find the Columbia Basin lacking resilience in fishing, hydropower, and water quality ��� sectors mitigating the effects of development in the Columbia Basin, manifesting as overall negative trends in cooperation. However, the Columbia shows signs of increasing cooperation due recent inclusion of Tribal Nations in water management. Flexible and inclusive institutional responses to water resource development challenges, in the Mekong to rapid development on the mainstream and in the Columbia to negotiations over renewal of the Columbia River Treaty, are key determinants to whether or not each basin can halt the current negative trends and strengthen basin resilience to face the challenges now and those coming in the future. / Graduation date: 2013

Management Practices for Dealing with Uncertainty and Change : Social-Ecological Systems in Tanzania and Madagascar

Tengö, Maria January 2004 (has links)
The development of human societies rests on functioning ecosystems. This thesis builds on integrated theories of linked social-ecological systems and complex adaptive systems to increase the understanding of how to strengthen the capacity of ecosystems to generate services that sustain human well-being. In this work, I analyze such capacity in human-dominated production ecosystems in Tanzania and Madagascar, and how this capacity is related to local management practices. Resilience of social-ecological systems refers to the capacity to buffer change, to re-organize following disruption, and for adaptation and learning. In Papers I and II, qualitative interview methods are used for mapping and analyses of management practices in the agroecosystem of the Mbulu highlands, Northern Tanzania. Practices such as soil and water conservation, maintenance of habitats for pollinators and predators of pests, intercropping, and landscape diversification, act to buffer food production in a variable environment and sustain underlying ecological processes. The practices are embedded in a decentralized but nested system of institutions, such as communal land rights and social networks, that can buffer for localized disturbances such as temporary droughts. Paper II compares these findings with practices in a farming system in Sweden, and suggests that similar mechanisms for dealing with uncertainty and change can exist in spite of different biophysical conditions. In Papers III and IV, interviews are combined with GIS tools and vegetation sampling to study characteristics and dynamics of the dry forests of Androy, southern Madagascar. Paper III reports on a previously underestimated capacity of the dry forest of southern Madagascar to regenerate, showing areas of regeneration roughly equal areas of degenerated forest (18 700 ha). The pattern of forest regeneration, degradation, and stable cover during the period 1986-2000 was related to the enforcement of customary property rights (Paper III). Paper IV reports on a network of locally protected forest patches in Androy that is embedded in a landscape managed for agricultural or livestock production and contributes to the generation of ecosystem services and ecosystem resilience at a landscape scale. Forest protection is secured by local taboos that provide a well-functioning and legitimate sanctioning system related to religious beliefs. In Paper V, two spatial modeling tools are used to assess the generation of two services, crop pollination and seed dispersal, by the protected forest patches in southern Androy. The functioning of these services is dependent on the spatial configuration of protected patches in the fragmented landscape and can be highly vulnerable to even small changes in landscape forest cover. In conclusion, many of the identified practices are found to make ecological sense in the context of complex systems and contribute to the resilience of social-ecological systems. The thesis illustrates that the capacity of human-dominated production ecosystems to sustain a flow of desired ecosystem services is strongly associated with local management practices and the governance system that they are embedded in, and that, contrary to what is often assumed, local management can and does add resilience for desired ecosystem services. These findings have substantial policy implications, as insufficient recognition of the dynamics of social-ecological interactions is likely to lead to failure of schemes for human development and biodiversity conservation.

Self-forgiveness for women who terminated pregnancy in adolescence

Sebola, Botshelo Rachel 01 1900 (has links)
Literature reveals that reproductive coercion is a major contributor to unwanted pregnancy and a factor that influences the choice to terminate pregnancy in many adolescents. Adolescents represent a population vulnerable to a number of physical and psychological problems. Purpose The overall aim of this thesis was to develop a model of self-forgiveness for women who terminated pregnancy in adolescence. Objectives The study objectives are aligned according to the phases of the study as follows: Phase 1: Desk review Explore what is already known about the topic and identify gaps. Phase 2: Lived experiences of participants about TOP Explore the lived experiences of participants who terminated pregnancy in adolescence. Phase 3: Development of a model Develop a model of self-forgiveness for women who terminated pregnancy in adolescence. The social-ecological model (Bronfenbrenner 1992), through which individuals are understood to influence and be influenced by people, organisations, institutions, societal norms, rules and beliefs with whom they interact, was followed. The model offered a holistic framework for exploring interrelationships related to TOP Methodology A qualitative approach based on Heidegger (1962) interpretive phenomenological approach was used. The study was conducted at a Health Care Centre in Tshwane Municipality, Gauteng Province, South Africa. The population consisted of women, 20-35 years old, who terminated pregnancy in adolescence. A purposive and snowball sampling techniques were used to recruit 30 participants who had terminated pregnancy in adolescence. An interview guide was used to solicit information from participants. Audiotaped interviews were held at the time, date and place agreed by participants. Colaizzi’s (1978) approach of data analysis was used. Results Five major themes emerged, with 17 sub-themes as transgressing one of nature’s strongest instincts: the mother’s protection of her young; unplanned pregnancy; intra-and interpersonal relationships; experience of caring by health care professionals and a need for counselling. A model of self-forgiveness for women who did TOP in adolescence, based on the components of self-condemnation and self-blame, cultural and spiritual, as well as reproductive coercion, was developed. Conclusion Participants carried the burden of shame and guilt of having terminated pregnancy in adolescence. The influence of culture and religion were the major contributing factors to women failing to forgive themselves after termination of pregnancy. A model of self-forgiveness is needed to allow those who terminated pregnancy in adolescence to move on with their life. / Health Studies / D. Litt. et Phil. (Health Studies)

As perspectivas ambiental e socioambiental do desenvolvimento sustentável sinérgico e sua aplicabilidade

Horn, Luiz Fernando Del Rio 17 December 2009 (has links)
O que são o desenvolvimento sustentável, seus desdobramentos teóricos e suas implicações, pode não suscitar muitas dúvidas ao investigador da academia, mas sua aplicação real vem provocando intensos debates nas muitas ciências, em razão dos temas que o cercam: quase tudo pertinente ao sistema social, para não dizer tudo. A extensão de qualquer enfrentamento a tal tema não permite grandes concessões e exceções das diversas áreas do conhecimento, sob pena de incompletude de observação, esta por si naturalmente limitada ao seu ponto cego. Assim, alguns pontos latentes para o desenvolvimento sustentável foram alinhados nos respectivos capítulos, de maneira que, no último, o somatório de revisões redunda num representativo avanço. A iniciar, e por meio do resgate histórico crítico, buscou-se a melhor definição para o desenvolvimento sustentável na contemporaneidade. Esta é observada em veias reflexivas na sequência, para contextualização do leitor nesta modernidade avançada. O processo produtivo de consumo, com ênfase para este último, detém toda a atenção a seguir, permitindo o conhecimento das engrenagens econômicas motivacionais. Dando continuação, aborda-se o desenvolvimento sustentável sob o prisma do sistema jurídico brasileiro, no qual a matriz do direito entra em discussão. Por fim, faz-se uma revisão minuciosa dos principais movimentos e correntes ambientais e socioambientais, prestando-se para a revisão do desenvolvimento sustentável, agora sinérgico. / Submitted by Marcelo Teixeira (mvteixeira@ucs.br) on 2014-05-30T16:09:34Z No. of bitstreams: 1 Dissertacao Luiz Fernando del Rio Horn.pdf: 871974 bytes, checksum: 3db221d36f479c613c269122b5246c1f (MD5) / Made available in DSpace on 2014-05-30T16:09:34Z (GMT).
