Biological Stress and Sociocultural Reactions to Environmental Change on the Central Coast of Peru: A Case of the Lima From Huaca 20 in the Maranga Complex

Cleary, Megan Kathleen 01 December 2019 (has links)
This research evaluates the 469 excavated human skeletons of the pre-Hispanic Lima population from Huaca 20 in the Maranga Complex in modern-day Lima, Peru dating to the beginning of the Middle Horizon (ca. 600-900 AD), for evidence of biological stress. From ca. 562-594 CE drought conditions occurred west of the Andes mountains, presumably having an effect on the Lima population and potentially causing this population biological stress. The purpose of this research is to examine whether or not the prolonged drought period negatively impacted the Huaca 20 sample. To evaluate the biological impact of this environmental stress, methods based on the Global History of Health (Steckel et al, 2011) were employed. The Huaca 20 sample was separated according to stratigraphic evidence of significant flooding which marked the end of the drought conditions. The majority of biological stress markers evaluated showed no significant difference between time periods. This result may be due to factors such as migration, the state of preservation of the sample, the biological stress being of too short a duration to appear on the skeleton, and/or the Lima population’s ability to adapt to drought conditions through sociocultural strategies. Mortuary data was employed to further the understanding of the potential negative effects of the prolonged drought period. Based on the two radiocarbon dates collected at Huaca 20 and the evidence of the end of the drought in the form of at least two flooding events, shortly after the drought period Huaca 20 was not used for domestic purposes but shifted to use as a mortuary site. The majority of mortuary goods did not show a significant different between time periods. Undecorated spindle whorls and undecorated spindle whorls showed a significant decline between the pre-flood and peri-flood time periods. This decline may be related to a decline in access to resources. The findings add a biological perspective to the discussion of the possible effects of the prolonged drought period on the Lima. It also provides an basis for comparison of biological markers of stress with other contemporaneous Andean peoples, as well as other populations experiencing environmental stress. This research will further illuminate on periods of environmental stress, which have occurred throughout history. The better understood responses to environmental stress are both postivie and negative, the better the world community today can prepare for them.

The effect of selected academic development programmes on the academic performance of academic development students at a South African university : an empirical study.

Smith, Leonard Cowper January 2012 (has links)
Includes abstract. / Includes bibliographical references. / The case studies that make up this thesis cover the three largest academic development programmes at the University of Cape Town. A variety of statistical methods are used to estimate the effect of educational interventions in selected first- and second-year academic development courses on the academic performance of academic development students in these courses and through to graduation, relative to mainstream students. In general, research in this area in South Africa and internationally has been characterised by small sample sizes and a lack of statistical rigour. Few studies control for the range of independent variables that can affect students’ academic performance, in addition to the academic development programme or course, and the great majority ignore the sampleselection problem that arises in the selection of students for academic development and mainstream programmes. The theoretical rationale underpinning this thesis is informed by the postpositivist and evidence-based approaches to empirical investigation. Demographic, academic and other data for some 9000 students for the years 1999?2005 was obtained from the university’s data base and academic departments. Statistical techniques including multivariate analysis and propensity score matching are used in an attempt to finesse the problems associated with the use of non-experimental data as students are selected into different courses and programmes.

Responsible tourism in rural South Africa: lessons from two case studies on the Wild Coast

Van Doorn, Elena 25 February 2020 (has links)
In Post-Apartheid South Africa tourism was seen as an important tool for economic development and poverty alleviation, especially in rural communities. The term Responsible Tourism was adopted by government in the 1996 White Paper and encouraged tourism that creates competitive advantage, maintains natural, social and cultural diversity and promotes sustainable use of local resources. This study looks at two case studies on the Wild Coast of South Africa, namely; Coffee Shack in Coffee Bay and Bulungula Lodge in Nqileni, which have both been awarded for their responsible tourism efforts. Through a review of the literature, document analysis and semi-structured interviews, this thesis identified a set of responsible tourism criteria applicable to tourism ventures in rural South Africa, while also identifying some of the challenges that come with tourism development in rural areas. The study discusses how responsible tourism approaches and practices can enable not only job opportunities, but also contribute to improving basic living conditions and enhance education and skills development of local communities. Gaining ownership of the tourism venture, meaningful participation of local communities in management and decision making, equal power relations as well as sharing in the benefits were all found to be important enablers in the case studies. A responsible tourism approach also focuses on promoting sound environmental management practices, including respect for local cultures, institutions and local knowledge, thereby contributing to biodiversity conservation efforts and promoting sustainable livelihoods. The study recognised how partnerships with government and NGOs can enable better implementation of responsible tourism policies and approaches, while monitoring results and accreditation can measure these benefits delivered to the economy, community and environment.

The periphery as the centre: trajectories of responsibility and community support in contemporary Maputo, Mozambique

Oppenheim, Beth T January 2017 (has links)
Development researchers have long held a belief that developed states use their power to provide Aid or other forms of external assistance such as private philanthropy, assistance of Non-Governmental Organisations, and other private financing to underdeveloped, or developing, nations to achieve global economic and political stability. Development scholars (including geographers) have largely attributed this to a sense of responsibility. Many have assumed this assistance to travel in one direction, i.e. from Global North to Global South, thus overlooking the modalities of care and hospitality among individuals within countries of the Global South. In this thesis, I posit that looking at everyday modes of assistance at the community level would challenge scholars to re-think the ways in which place matters in development. Analysing qualitative data gathered through interviews and focus groups in two neighbourhoods in Maputo, Mozambique, this study is ultimately an investigation of proximity. I argue that the closeness of people in these complex community relationships matters in three ways: (i) the everyday practices of assistance in these communities are modes of resistance to an oppressive state; (ii) forms of assistance serve as expressions of local (as opposed to national) identity; and (iii) religious institutions play a significant role in fostering public discourse, rather than motivating assistance itself. In speaking more specifically about how proximity matters, this study contributes uniquely to the growing realisation that development must come from within.

Student food security: the (dis)connection between student food experiences, sustainability and green spaces from the lens of food security

Drewett, Jessica 18 February 2019 (has links)
The food security of university students in South Africa is an area of research which is becoming increasingly researched and recognised. Internationally, there has been research into university student food security, recognition of student food insecurity and the links to academic success, and the idea of secure campus food systems. Approaches documented in the literature from the global North include the establishment of food banks and pantries, and the use of university green space in order to feed university students and decrease student food insecurity. Limited research on food security of university students in South Africa has been conducted, but this is increasing. Universities around the world are becoming increasingly aware and active in examining their ecological impacts as universities, and placing sustainability on the university agenda. This research explores the current narratives of student food security, campus food initiatives and the (dis)connection between green spaces and student food security responses at a university in South Africa. In order to achieve the research aim, three objectives were identified. The first objective was to review the global literature of university student food security, the use of green spaces on university campuses as a food security response. The second objective investigated student food security dialogues, and the third objective included the examination of university based food initiatives and university policy documents and reports, and assessing the integration of aspects of student food security. This exploratory research used a mixed methods approach, using a mixture of quantitative and qualitative data, by way of literature review, document analysis, online quantitative surveys and semi structured interviews in order to explore the narrative of student food security in South Africa, as well as the link between university campus sustainability and student food security. Dominant themes which arose from the research include food costs and affordability, in addition to food quality and health. It was found that there is a disconnection between student food experiences, sustainability and green spaces. While the links between green space and student food security may be relevant in Northern contexts, more pressing systemic issues require attention in the context of South Africa, thus adding to the complexity of how student food security is approached in the country. This exploratory research highlights the need for further research to be conducted in the area of student food security.

Marine Protected Areas in Kenya: perceptions of local communities of costs and benefits of MPAs and their governance

Achieng, Stephanie 11 March 2020 (has links)
This study aimed to examine the perceptions of two local communities living adjacent to Mombasa Marine National Park and Reserve (MMNP&R) and Kuruwitu community closure (tengefu) in Kenya regarding the benefits and impacts of the MPA on their livelihoods. A secondary aim was to compare the perceptions of these two communities in relation to the MPA management models employed at the two study sites. The research employed a case study approach and undertook focus group meetings and key informant interviews at each case study site and with relevant organisations. Key findings from the research revealed that both sites experienced diversification of livelihoods, however the diversification was for different reasons. The Bamburi community members stated that the park generated benefits such as new forms of employment linked to tourism, beach security, increased variety of corals and fish species as well as improved infrastructure. The Kuruwitu community perceived the closure to have resulted in various benefits but in particular social benefits, such as women empowerment, ownership of resources, co-existence among resource users and community exchange visits were highlighted. However, both cases also identified various negative impacts including tensions due to an increase in migrant fishers, illegal access and poaching and the use of unsustainable gear. Furthermore, the direct resource users (fishers) in both case study sites felt that their fishing grounds had been drastically reduced due to the establishment of the park and tengefu which negatively affected their fish catches and livelihoods, leading to decreased support for the conservation initiatives. Therefore, the fishers in both study sites were more negative about the protected areas compared to the other resource users. Kuruwitu, in particular, identified perceived fear of the loss of their marine area to privatisation, inequitable sharing of benefits by their leadership group and limited involvement of women in decision- making as primary negative concerns. On the other hand, concerns about minimal involvement in management decisions during and after park inception were expressed by participants at the Bamburi study site. In addition, the lack of transparency in the management and use of revenue derived from the state- run MMNP&R further aggravated tensions between the state and the adjacent communities as well as severe penalties set for transgressions on locals by marine park authorities at MMNP&R. With the introduction of co-management through the Beach Management Units (BMUs) in Kenya in the year 2007, it was expected that stakeholder participation would be increased, however, the Bamburi community lamented over lack of proper representation within the BMUs which they claimed gave outsiders more power. While both communities, especially Kuruwitu identified a number of nongovernmental organisations (NGOs) that aided in fulfilling the community’s socio- economic and ecological objectives, they were much more central to achieving socio-ecological objectives at Kuruwitu than at Bamburi. These NGOs and other stakeholders, however, became much more engaged at MMNP&R after the inception of the BMUs. Based on the findings, it was evident that the community- based co-management conservation approach at Kuruwitu generated more social benefits to the community than the state-centred co- managed conservation approach at MMNP&R. Loss of access to traditional fishing grounds, perceived loss of benefits and increased social costs triggered illegal access into the state park, therefore, fuelling conflicts and exacerbating tensions between the community and the state as well as tensions between various management institutions regarding overlapping mandates. Implementing genuine co-management approaches are key to fostering inclusivity, accountability, legitimacy and support for marine conservation initiatives.

Developing responsible nature-based tourism in the Mount Elgon region of Kenya: integrated approaches

Kariithi, Jacqueline Nduta January 2016 (has links)
Tourism development theory and practical implementation has evolved over time. In an attempt to find approaches that can minimise the negative impacts of tourism, research has been emphasising efforts to reduce the tensions created by the interaction between the tourism industry, tourists, the environment and host communities. Furthermore, the sustainability debate has framed these discussions on meeting the triple bottom line in adherence to the goals of sustainable development. Much of this research draws on constructivist and realist theories that advocate for tourism as a tool for development. Though this study appreciates the various methodologies recommended for sustainable tourism development, such methodologies lack a holistic approach that can concurrently address a destination's economic, environmental and socio-cultural challenges. This research therefore focuses on integrating approaches to the tourism development process and the implications of such an approach for the triple bottom line. The Mount Elgon region of Kenya comprise two protected areas and one national park, and serves as a case study to better understand the application of an integrated approach. The research is informed by conceptual insights into sustainable tourism that underpin planning. Planning is central to outlining methodologies that can foster tourism in underdeveloped regions. The conceptual framework used in this study proposes the application of three approaches, namely ecosystem management, multistakeholder engagement and geospatial analysis of the tourism resource base. Each of these approaches is aligned to a key positive output of tourism development in protected areas. These outputs, as identified in literature, are biodiversity conservation, socio-cultural enhancement and economic growth. They are central to understanding the significance of the three pillars of sustainability. The research utilised a mixed-method approach that included qualitative analysis by means of policy document review, in-depth and semi-structured interviews, questionnaires, participant observation and participatory rural appraisals. These different data sources were employed to develop an integrative framework for tourism development in the protected areas within the Mount Elgon region. Content analysis was used to study the open-ended data, all the while considering the economic, environmental, and socio-cultural dimensions. The analysis of these three dimensions in relation to the study area revealed many of the challenges that stakeholders in tourism development in the Mount Elgon region face. By exploring these methodological avenues, the research identifies the linkages and overlaps that can be united in an integrative framework. Initial outputs consist of an analysis of the implications of creating integrated approaches and synergising it into an integrative framework for the purpose of developing tourism in protected areas. The findings indicate that integrated approaches can be applied to understand the roles of the primary stakeholders in building or enhancing tourist destinations, local participation, environmental preservation and conservation and market sustainability of tourism enterprise development. The intention is to create a mechanism that will go beyond providing recommendations for Mount Elgon region stakeholders to embrace responsible nature-based tourism, and that allows researchers to adopt this methodology in similar environments and destinations.

What Do You Want to Eat? A Descriptive Study of Native Hawaiian and Pacific Islanders' Home Food Environment

Ruda, Petr 01 April 2015 (has links)
Objectives: Home food environments are created when families stock their kitchens with food, which contributes to their dietary patterns and weight management. Native Hawaiians and Pacific Islanders (NPHIs) have a high prevalence of overweight and obesity. A description of their home food environment can help nurses understand NHPIs' dietary patterns. Our purpose was to describe NHPIs' home food environments by analyzing grocery store and restaurant receipts. Design and Sample: This descriptive study used analyzed qualitative and quantitative data from eight NHPI families, collected over an 8-week period. Measures: Grocery store and restaurant receipts were analyzed with descriptive statistics. Families' dietary patterns were studied with open-ended questions and compared to receipt data. Results: Food groups with the highest percent expenditures included combination foods (20%), protein foods (19%), and empty calorie food and drinks (11%). The lowest percent expenditures included fruits (8%), grains (7%), vegetables (7%), and dairy (6%). Families visited restaurants zero to 10 times (M = 2) per week. Conclusions: Results can help nurses address NHPIs' home food environment challenges by increasing their awareness of typical food purchases and helping NHPIs assess their own grocery and restaurant purchases and improve their own home food environments.

Declaring urban conservation areas: the Art Deco townscape of Vredehoek, Cape Town

Jongens, Nicoline January 2017 (has links)
The research question posed in this study asks what qualities, characteristics and cultural significance need to be embodied within an urban environment that make the area worthy of conservation-oriented protection through laws and policies. The research question was explored through an assessment of the townscape of Vredehoek, an informally(1) proposed conservation area in Cape Town where there is a relatively high concentration of Art Deco buildings. The selection of Vredehoek as a laboratory within which to ask this question is due to the presence of contested opinions amongst various stakeholders and heritage-claimants about the cultural significance embodied within the built fabric of this place. This study aimed to identify what elements of the built environment of Vredehoek are of special interest, what qualities and characteristics these elements of special interest embody, to understand and articulate the values that inform these qualities, and to identify to whom these elements are valuable and why. Criteria were established with which to determine whether the identified qualities and values are special enough that when synthesised, the resultant significance of the place warrants protection through heritage area designation. The criteria developed with which to assess and evaluate proposed urban conservation areas, including Vredehoek, require that such environments need to embody cultural significance and characteristics informed by an urban history reflected in its authentic manifestations developed over time through continuity of use with a high townscape quality established primarily through the aesthetic unity of its component parts. Through historical research, the studying, mapping and analysis of the area's urban morphology, built environment and natural landscape, and the identification and evaluation of values held by heritage-claimants and views held by those critical of Vredehoek's proposed designation, evidence regarding the conservation-worthiness of Vredehoek has been assembled and assessed within the framework of criteria developed to evaluate heritage area designation. It has been found that the environment of Vredehoek does not embody high townscape quality nor does a strong aesthetic unity of its components exist. Furthermore, the area is not a richly layered environment reflecting continuity of use, the existence of cultural significance within the place is limited to a relatively small part of the townscape - a collection of Art Deco buildings demonstrating a moderate degree of architectural merit. Thus the environment of Vredehoek does not meet the criteria required for heritage area conservation.

Integrating urban wastelands, islands, and landmarks of modernity into current urbanity

Boshoff, Mia January 2020 (has links)
Current city growth patterns are largely influenced by the practices and theories of the past, particularly functionalist theory. New intentions and proposals are constantly confronted with this legacy of the past, constituting a challenge for positive change, often tipping the balance for standard solutions. Urban wastelands are the result of both, zoning, and town planning requirements, which in the particular case of South Africa have also been used as barriers. These spaces are undefined, often derelict and/or inaccessible; they pose a major issue and a source of conflict among the communities. Current city planning has been unable to deal with these spaces in an effective manner, which in turns include the structures, often stand-alone ones that struggle to find a use or larger meaning for the greater context. It is necessary therefore, to re-envision the role these spaces can play in creating continuity of the urban fabric, generating a meaningful place that includes the immediate community as a viable solution for re-integration. This thesis explores a strategy for addressing these issues at the urban scale, and an architectural strategy for integrating derelict building in the specific scale. / Mini Dissertation (MArch (Prof))--University of Pretoria, 2020. / Architecture / MArch (Prof) / Unrestricted
