The life history, use and socio-economics of the edible stinkbug encosternum delegorguei (Hemiptera: Tessaratomidae), in South AfricaDzerefos, Catherine Maria 11 August 2014 (has links)
A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg, 2014. / Entomophagy, the consumption of insects, has attracted interest as a low input minilivestock with good nutritional value. The inflated stinkbug, Encosternum delegorguei, is an appetizing food, a hangover cure and a trade item in South Africa, Malawi and Zimbabwe yet very little is known about it. This study comprehensively integrates plant aspects (food and shelter) and insect biology (distribution, life cycle and fecundity) with socio-economic and conservation aspects. Firstly, E. delegorguei was observed in outdoor insectaries where it exhibited reproductive winter diapause and declining abdominal fat content attributed to non-feeding. In spring (September) E. delegorguei fed on Combretum imberbe, Combretum molle (Combretaceae), Peltophorum africanum (Fabaceae), and to a lesser degree on Dodonaea viscosa (Sapindaceae) and the grass Pennisetum clandestinum (Poaceae). Copulation occurred during October/November but eclosion was reduced by the egg parasitoid wasp, Anastatus sp. Secondly, structured interview schedules with 106 harvesters indicated that an estimated total of 3803 + 43.4 kg (mean+S.E.) dry stinkbugs was harvested with an annual gross per capita income of =US$ 345. In South Africa stinkbugs are consumed by two locally separate ethnic groups the Vhavenda and Mapulana, with a third group, the Bolobedu selling them. Ethnic differences in nomenclature and oral history, methods of collection and preparation, as well as perceptions pertaining to availability were documented between the three groups. Damage to host trees occurred when harvesters poached from pine plantations or private land, whereas, in communal-lands, sustainable methods proliferated. Using a regional maximum entropy modelling method (MAXENT) on winter locations of E. delegorguei known to harvesters, current and future distribution scenarios were identified. Winter precipitation and to a lesser degree summer precipitation and winter temperature were key climatic variables limiting the regional distribution of E. delegorguei. Moreover, potential new sites unknown to harvesters or areas where minilivestock initiatives could be piloted have been highlighted for further investigation. Opportunities to reduce impediments to collection and trade are discussed in a sustainable framework. For example legitimisation of harvesting and introduction of a collection funnel to reduce conflicts with plantation, orchard and private land managers. Awareness and optimal use of beneficial bio-resources, such as E. delegorguei, could encourage community driven habitat stewardship.

Paradoxical development: China's early industrialization in the late nineteenth century.Liu, Xiaozhu. January 1995 (has links)
This dissertation studies China's first industrializing efforts to transform its navigation, cotton textiles and banking in the late nineteenth century, and analyzes the paradoxical roles of the state and culture in achieving development. It argues that successful late development is dependent on state policies that emphasize state-society connectedness and tradition-modernity continuity. In late Qing China, the state-midwifed industrial projects faced both intensive competition from foreign firms and resistance from domestic vested interests. Because key resource factors such as capital, production technology, and management skill were scarce and distributed unevenly across multiple sectors, the state officials had to redirect the resource flows in order to found new industries. The state had to perform an essential function of creative destruction, without which social groups in non-state sectors would be less likely to embrace changes, but the ultimate success of new industries depended on a societal consolidation that redefined the state-society relationship. This study also shows that culture was a double-edged sword with great potential for lubricating industrial transformation. The promoters of development created myths, symbols and beliefs to legitimize their industrializing efforts. They made a constant effort to reinterpret tradition in order to find compatibility between the foreign and domestic systems. The distinctive sectoral paths taken by navigation, cotton textiles and banking represented different patterns of state-society cooperation for achieving development. Each sector had distinct production technologies and product structure, and was endowed with distinct sectoral institutions and other legacies. These endowments constrained choices of every new industry, but it was a combination of structural factors and industry's responsive strategies that explained why some enterprises succeeded while others failed. A project was more likely to succeed if there was greater state-society connectedness and cultural compatibility. Steam navigation was the most successful among the three, followed by cotton textiles. Banking was the least successful.

Socio-economic and demographic determinants of maternal mortality risks in ZambiaChirwa-Banda, Pamela January 2016 (has links)
A thesis submitted to the faculty of Humanities, University of
the Witwatersrand, Johannesburg, South Africa; in fulfillment of
the requirements for the award of PhD in Demography and
Population Studies. September, 2016. / Background: While there has been a significant global reduction in maternal mortality rates from 546 000 in 1990 to 287 000 in 2010 (Zureick-Brown et al., 2013;Merdad, et al., 2013), maternal mortality in Zambia continues to be above at 483 per 100 000 live births, eluding the millennium development target of 162 (CSO, 2012). Data on maternal mortality are not disaggregated by provinces. Various studies on maternal mortality conducted in Zambia (Ahmed et al., 1999; Banda et al., 2007; Hazemba & Siziya, 2009; Kilpatrick, Crabtree & Kemp, 2002) have evaluated maternal deaths at national level using direct death inquiry and though it is useful for international comparisons, neither one of these approaches are appropriate for evaluating maternal mortality in small districts where safe motherhood initiatives are often carried out. These studies have rarely included neighbourhood influence on maternal mortality risks. Moreover, no known study has attempted to use the Zambia Demographic and Health Survey maternal health indicators to evaluate maternal mortality by regions in Zambia. Yet, analyses of differentials within small districts provide an improved awareness of the social situation in which the risks are high for regional priority interventions. In addition, other researchers (Achia & Mageto 2015; Stephenson & Elfstrom 2012) have all posted that inclusion of neighbourhood level variables is helpful to understand several maternal health outcomes.
Objective: Guided by the conceptual framework developed by McCarthy & Maine (1992), this study contributes the new method of use of the mean Maternal Death Risk Factor Index model to estimate the levels and differentials in the risks of maternal mortality by regions and enhance the understanding of determinants of maternal mortality risks. This model is helpful in that it highlights regional and socioeconomic differentials in maternal mortality risks and ranks regions
according to their potential maternal mortality burdens. Benchmarks are set by using this model and indicators are used to identify probable high-risk areas or regions.
Methodology: The study utilised existing data sources from the 2007 Demographic and Health Surveys (DHS) and 2011-2013 Health Management Information System Routine Data (HMIS). Bivariate analysis was utilised to investigate the distribution and differentials in exposure to maternal mortality risks. Multilevel logistic regression was performed to investigate the independent and moderating functions of neighbourhood aspects on exposure to maternal mortality risks and the moderating functions of neighbourhood causes on the relationship between individual circumstances and exposure to maternal mortality risks. The mean Maternal Death Risk Factor Index (MDRFI) model that uses the history of individual women health indicators was used to predict maternal mortality and highlight regional and socioeconomic differentials of maternal mortality risks. The analysis was based on 5 410 women aged 15 to 49 who had a live birth in the five years prior to the 2007 Zambian Demographic and Health Surveys. The HMIS 2011-2013 data was also utilised for a comparative analysis and complementing DHS data on maternal health matters in Zambia.
Results: The predicted maternal mortality ratios (MMRs) values by region showed larger regional disparities. All the seven rural regions had MMR above the national average (591/100 000 live births); the highest being in Northern Zambia (738 per 100 000 live births) and Central Zambia (679 per 100 000 live births). The predicted ratios in the two urban regions of Lusaka and Copper-belt were significantly below the national average. The findings of both bivariate and multivariate analyses showed that skilled birth attendance at delivery significantly lowered the risks of exposure to adverse pregnancy outcome. The likelihood of using skilled personnel at birth was advanced for women who resided in neighbourhoods, with advanced
proportion of women who utilized skilled delivery at birth compared to women who lived in neighbourhoods that had a high proportion of women giving birth at home. The outcome from the multilevel analysis showed that the consequence of individual and neighbourhood influences on the exposure to high risk pregnancy in Zambia operates at different levels. Women with no education were found to be more exposed to high risk pregnancy than women with post primary education. The rate of women in the neighbourhood who utilized skilled birth attendance had a strong positive impact on the reduction of exposure to high risk pregnancy. In the analysis of autonomy level – although results indicated that women with low autonomy had higher odds of exposure to high risk pregnancy compared to women with high autonomy – the results were not significant, and therefore autonomy level in terms of exposure to high risk pregnancy was not supported in this study.
Conclusion: The MDRFI model is much easier to use at any level and quicker to forecast interventions as well as prevent probable risks compared to the use of the sisterhood method. The model proposed here could serve as the basis for a new and better system of mortality estimation for populations with incomplete data. The results reveal a number of challenges to confront with the purpose of reducing maternal mortality in Zambia. Women’s high risk reproductive behaviours and the use of imperative fertility healthcare utilities have yet to increase considerably to result in a decrease in maternal deaths in the nation. The continuous disparities in maternal death hardship by province, rural-urban dwelling and socioeconomic position of the society further heightened the issue, making attempts to enhance maternal health and thereby decrease maternal deaths more demanding. Advancements to lower maternal mortality should either lessen the probability that a woman will become pregnant or lower the possibility that a
pregnant woman will experience adverse reactions during pregnancy or childbirth or better the outcomes for women with complex pregnancies.
This research makes it evident that programs to combat maternal mortality risks in the country require several avenues that embrace diverse protective measures looking beyond the individual level as women’s health is essentially affected by their social environment. The amount of differential at neighbourhood and individual level found in our study indicates the need to contextualise efforts to increase resources towards mitigating exposure to high risk pregnancy. Hence, adopting neighbourhood-specific strategies along with identifying and addressing neighbourhood factors affecting the exposure to high risk pregnancy would give better results. The use of multilevel analysis in this research has shown that individual and neighbourhood aspects are crucial components associated with the exposure to high risk pregnancy. The multilevel framework demonstrated crucial neighbourhood differentials in the exposure to high risk pregnancy. Improving quality and access to health services is essential if the most deprived are to benefit. The Ministry of Health should align its plans of action to Zambia’s development strategy articulated in its own Vision 2030. Neighbourhood health workers need to be involved in sensitising pregnant women about the risks of maternal mortality, for instance short birth interval, risky maternal age and danger signs during pregnancy.
To close the gap in exposure to high risk pregnancy between neighbourhoods, interventions should aim at poverty reduction, increasing neighbourhood maternal education and facility delivery in deprived neighbourhoods. The model used in this study could serve as the basis for a new and better system of mortality estimation for populations with incomplete data and will be much easier to use at any level, as well as vital for quick forecasting of priority interventions. / GR2017

Pluri-residentiality and the multi-house home: an investigation into the second home ownership of the black elite residents of SowetoSingo, Tumelo January 2016 (has links)
A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of requirements for the degree of Master of Science. Johannesburg, November 2015. / Globally, people are connected to multiple homes. This connection develops through
ownership and place attachment. Second home tourism research explores the
ownership and place attachment to multiple homes for the purpose of leisure. Whilst
second home tourism research has been conducted extensively in the Global North,
focusing mainly on leisure, the same cannot be said for the Global South. In South
Africa, there is little research conducted on the local wealthy black population and
the connection to ownership and place attachment to additional/second homes. The
history of racial, socio-economic and spatial segregation in South Africa has
facilitated the unique development of the connection to multiple homes for the black
populations. Using the current second home tourism literature, together with the
legislative history of South Africa, this research hopes to develop open and inclusive
explanations of the second home phenomenon for the case of the influential black
elite residents in South Africa. This dissertation explores the link that sixty-nine black
elite residents of greater Johannesburg suburbs have with their additional homes
that are located in Soweto and other regions in sub-Saharan Africa. To achieve this,
a largely qualitative methodology set was implemented through the use of in-depth
semi-structured interviews and thematic content analysis was utilised for the
analysis. To conclude, the results of this dissertation dispute certain aspects of
concepts used in current second home literature. It is also emphasized that it is
important to rethink and re-conceptualize the international ideas of circulation,
mobility and pluri-residentiality, when attempting to appropriately adapt these
concepts South Africa.

Relationships and CommunicationPersson, Petra January 2013 (has links)
Chapter one of this thesis examines how tying social insurance to marriage influences matching and marital decisions in the context of Sweden, and draws implications for when it is optimal to separate social insurance from marriage in modern societies. Chapter two analyzes firms' communication strategies in a market where consumers face attention constraints, and discusses regulation that can protect consumers from exploitation. Chapter three studies communication and coercion in the presence of an altruistic relationship, and offers a benevolent rationale for constraining liberty to protect individuals from self-harm, for example through safety mandates.

The Socioeconomics of State Formation in Medieval AfghanistanFiske, George January 2012 (has links)
This study examines the socioeconomics of state formation in medieval Afghanistan in historical and historiographic terms. It outlines the thousand year history of Ghaznavid historiography by treating primary and secondary sources as a continuum of perspectives, demonstrating the persistent problems of dynastic and political thinking across periods and cultures. It conceptualizes the geography of Ghaznavid origins by framing their rise within specific landscapes and histories of state formation, favoring time over space as much as possible and reintegrating their experience with the general histories of Iran, Central Asia, and India. Once the grand narrative is illustrated, the scope narrows to the dual process of monetization and urbanization in Samanid territory in order to approach Ghaznavid obstacles to state formation. The socioeconomic narrative then shifts to political and military specifics to demythologize the rise of the Ghaznavids in terms of the framing contexts described in the previous chapters. Finally, the study specifies the exact combination of culture and history which the Ghaznavids exemplified to show their particular and universal character and suggest future paths for research.

Ground Shaking and Socio-Economic Impacts of EarthquakesLackner, Stephanie January 2017 (has links)
Earthquake impacts are widely studied across numerous disciplines. However, no systematic approach to quantify the "size" of an earthquake for impact research exists. This work provides the first comprehensive discussion and empirical study on how to measure the natural hazard of an earthquake for application in the social sciences. A data set consisting of all relevant global ground shaking from 1973 to 2015 combined with population exposure data and impact data is constructed based on 14,608 ShakeMaps. The empirical work shows that magnitude is not a good proxy for shaking and that measures of total earthquake size based on ground motion parameters perform better in explaining impacts than magnitude. In particular peak ground acceleration (PGA) performs well and is applied for two separate impact analyses. First, the relationship between earthquake ground shaking and public health related variables in California is investigated. Second, the global impact of earthquake ground shaking on long-run economic growth is studied. Furthermore, this work introduces the concept of a shaking center as well as a shaking centroid and provides the first global statistics on the area exposed to strong ground shaking for a given earthquake.

The implications of global trading for North/South relations: a case for fair tradeQuinn, Alyson 05 1900 (has links)
Since mercantilism, which began in the mid 1600s, there have been numerous
systemic changes in the global trading system. The most significant changes have
been colonialism, the slave trade, peasant enclosures, industrialization and the
formation of global economic institutions. Each one of these has had a marked effect
on the distribution of resources and the wealth generated from their manufacture.
Mercantilism, a theory related to trade and commerce, brought about intense
competition amongst Northern countries in order to secure markets and resources.
Colonialism was a way of assuring traders access to both primary resources and
overseas markets in Southern countries. This pattern of trading whereby Southern
countries provide the raw resources for the benefit of those in the North is still
relevant, and has contributed significantly to divisions in wealth between the
hemispheres.
By the early 1800's mercantilists posed a threat to the aristocratic classes,
which found themselves land rich but money poor. This, along with the growing
movement towards industrialization, led to the eviction of peasants from land they
had lived on for centuries. Two sources of cheap labour became available. Peasants
who were desperate to find work in order to survive, and those deemed to be slaves
from the developing world. Their labour was used to clear land for cultivation and
for factory work. This combination of cheap labour and access to primary resources
from the South enabled Northern countries to forge ahead with the industrialization
of their economies.
The year 1944 was an important year for global trading. Three institutions,
namely the International Monetary Fund (IMF), the World Bank and the General
Agreement on Tarriffs and Trade (GATT) were formed shortly thereafter. These
international organisations would help solidify globally the ideology of laissez -faire
economics. They would also play a direct role in influencing Southern governments
to reduce trade barriers. It is claimed by critics that the IMF, the World Bank and
GATT have used their power to uphold policies which have pried open Southern
economies for the gain of those in the North. Critics believe these policies have been
particulary negative for those living a subsistence lifestyle. Poverty in the
developing world is currently at catasrophic levels with 34,000 children dying every "
day from malnutrition and disease. Some charge the IMF, World Bank and GATT for
increasing the vulnerability of the poor and ecological destruction.
Fair trade is a system of trade which deliberately seeks to establish a more
equal basis of exchange between the two geographical hemispheres. It helps to
counter some of the imbalances of the current trading system. With the commitment
of Alternative trading organisations (ATO's) thousands of men, women and children
have secured a lifestyle which is both economically viable and ecologically
sustainable. The challenge for fair trading is to apply alternative trade models more
widely, and to promote fair trading as a part of mainstream commercial activity.
One way the fair trading system is doing this is through labelling products sold in
supermarkets with a fair trade label. Those products with a fair trade label have
passed the fair trading criteria agreed to by the International Federation for
Alternative Trading.
Social Work is one of many professions that could help support fair trading.
By organising fair trade networks as part of social development practice, social work
could be active in supporting an economic system which empowers those who are
most disadvantaged, and thereby reduces the inequality perpetuated by the current
trading system.
There are a number of other key roles for social workers. They could educate
the public about global economic issues through conferences, workshops and
writing educational material. Another role for social workers is that of negotiation.
Social workers in the international development field would be in a good position to
link Southern producer groups to Northern fair trading businesses. They could also
link socially responsible business in the North to marginalised groups in their own
countries. A third role for social workers committed to fair trading, is research.
Topics could include ongoing analysis of the social and environmental effects of the
current trading system, exploring the effectiveness of various alternative trading
models and research on factors that could help facilitate the growth of socially
responsible business.
There are three international bodies which help social workers maintain a global
perspective. They are the IFSW (International Federation of Social Work), the LASSW
(International Association of Schools of Social Work) and the ICSW (International
Council on Social Welfare).

Happiness in the private physiotherapy sector of South AfricaElliot, Michael January 2017 (has links)
There is limited research pertaining to assessing the happiness levels of various disciplines within the healthcare industry. Furthermore, happiness and physiotherapy studies are two research areas that are not necessarily associated with one another on a global perspective. Hence, the happiness levels have not been adequately established for private physiotherapists. This treatise is the first attempt to evaluate the happiness levels of private physiotherapists in South Africa. A thorough literature review was conducted to determine the current climate of happiness studies pertaining to the business industry, with focus on private physiotherapy businesses in the healthcare sector. The literature review enabled the development of a hypothesised model, which was tested with quantitative techniques consisting of a questionnaire, data collection and statistical analysis. The research confirmed that influence, social relations, life balance, optimism, work and leisure are all positively associated with the happiness levels of private physiotherapists in South Africa. These variables are recommended as key focus areas for physiotherapy business owners to address, in order to positively affect happiness levels in the workplace and thereby create favourable bottom line results. In accordance with the reviewed literature and the findings of this treatise, by adequately addressing these variables the business owners of physiotherapy practices will generate a workforce that are more productive, demonstrate greater collaboration with colleagues and customers, produce happier customers, are more positively energised and are less absent and more loyal to the business. It is recommended that the proposed model is tested to provide further benefit to the industry by constructing evidence-based retention and recruitment strategies for high performing private physiotherapy staff.

South African low income housing policy : a wobbly pillar, a cornerstone for development, or a lever for socio-economic change for the state?Nyandu, Zandile January 2013 (has links)
The Constitution of the Republic of South Africa, 108 of 1996 (the Constitution), affords all South Africa citizens the inalienable right to housing. Since 1994 there have been many policies which include the Reconstruction and Development Programme (RDP) of 1994; and the Housing Act, 1997 (Act No. 107 of 1997). Currently the most fundamental housing policy is the National Department‟s mandate is the Comprehensive Plan for the Development of Sustainable Human Settlements, 2004.
The first objective of this study was to analyse whether South Africa is viewed as a welfare or a developmental state. The second objective of this study was to assess whether the South African Low Income Housing Policy contained in the comprehensive plan for the development of sustainable human settlements (2004) is a wobbly pillar of the state, a cornerstone for development or a lever for socio economic change.
This research study comprised of sixteen in-depth interviews with South African housing policy developers and implementers. The interviews were based on semi-structured interview questions. The study followed a qualitative technique and an exploratory research approach. The study found that South Africa is not viewed as a welfare state, nor is it viewed as a developmental state. It is viewed as an intermediary state that has strong policies and institutions that support a developmental agenda. The study further found that the South African housing policy is not viewed as a wobbly pillar of the state but it is viewed as a cornerstone for development and a lever for socio-economic change.
There was lack of diversity because all interviews were based in Kwa Zulu Natal and Gauteng, which are only two of the nine provinces of South Africa. A total of ten recommendations were made to policy developers, implementers and for future research. / Dissertation (MBA)--University of Pretoria, 2013. / zkgibs2014 / Gordon Institute of Business Science (GIBS) / MBA / Unrestricted
