Caribbean Hinduism on the Move

Pillai, Rupa 10 April 2018 (has links)
This dissertation is an ethnographic study of how members of the Indo-Guyanese community traveled from Guyana to New York City, carrying with them distinct understandings of Hinduism informed by their multiple dislocations and how they utilize religion as ideology and practice to help cultivate their identities as Indo-Guyanese Americans. I argue religion as a mobile concept, what I have termed as ‘religion on the move,’ gives a theoretical frame to understand how devotees adapt religion to help them navigate their identities in unknown territories. By studying more than devout individuals in places of worship, I have followed Caribbean Hinduism and Indo-Guyanese Hindus in New York City to various sites to appreciate how religion informs their experiences, operates on different scales (spatially, politically, and temporally), and negotiates power structures. I found that the Indo-Guyanese Hindu community asserts their ethnicity through Caribbean Hinduism to become visible, to overcome marginalization and to claim belonging in the United States. / 2019-10-17

Mobilidades culturais e alteridades em Relato de um certo oriente e sua pré-tradução árabe / Mobilities and alterities in Tail of a Certain Orient and its Arabic pre-translation

Gebaly, Maged Talaat Mohamed Ahmed El 26 November 2012 (has links)
Esta tese tem como objetivo discutir as variadas manifestações de mobilidades culturais e suas consequentes relações de alteridades no romance Relato de um certo oriente de Milton Hatoum, partindo do suposto de que a alteridade é parte constituinte da subjetividade e da relação humana de diferença e identidade com o Outro; e, ao mesmo tempo, analisar o processo intercultural da pré-tradução para a língua árabe de quatro capítulos do Relato de um certo oriente. Nesse sentido, este trabalho está focado em dois lócus das mobilidades culturais das alteridades: a narrativa de memória da imigração e a tradução literária. / This thesis aims to discuss the various manifestations of cultural mobilities and its consequent relations of alterities in the novel Tale of Certain Orient of Milton Hatoum, assuming that otherness is a constituent part of human subjectivity and its relationship of difference and identity with the Other; and at the same time we intend also to analyze the processo of intercultural pretranslation into Arabic of four chapters of the novel. In this sense, this work is focused on two locals of cultural mobilities of alterities: the narrative memory of immigration and literary translation.

Dendritic poly(3-hexylthiophene) star copolymer systems for next generation bulk heterojunction organic photovoltaic cells

Yonkeu, Anne Lutgarde Djoumessi January 2018 (has links)
Philosophiae Doctor - PhD / The continuous increase in energy consumption and decrease in fossil fuels reserves are a primary concern worldwide; especially for South Africa. Therefore, there is an urgent need for alternative energy resources that will be sustainable, and environmentally friendly in order to tackle the ecological degradation generated by the use of fossil fuels. Among many energy ‘niches’, solar energy appears to be one of the most promising and reliable for the African continent because of the constant availability of sun light. Organic conjugated polymers have been identified as suitable materials to ensure proper design and fabrication of flexible, easy to process and cost-effective solar cells. Their tendency to exhibit good semiconducting properties and their capability to absorb photons from the sunlight and convert it into electrical energy are important features that justify their use in organic photovoltaic cells. Many different polymers have been investigated as either electron donating or electron accepting materials. Among them, poly(3-hexylthiophene) is one of the best electron donor materials that have been used in organic photovoltaic cells. It is a good light absorber and its Highest Occupied Molecular Orbital (HOMO) energy level is suitable to allow electron transfer into an appropriate electron acceptor. On the other hand, the molecular ordering found in dendrimers attracted some interest in the field of photovoltaics as this feature can ensure a constant flow of charges. In this work, I hereby report for the first time, the chemical synthesis of a highly crystalline dendritic star copolymer generation 1 poly(propylene thiophenoimine)-co-poly(3-hexylthiophene) (G1PPT-co-P3HT) with high molecular weight and investigate its application as donating material in bulk heterojunction organic photovoltaics.

Young people, alcohol and urban life

Wilkinson, Samantha January 2015 (has links)
This thesis explores the alcohol consumption practices and experiences of 40 young people, aged 15-24, living in the suburban case study locations of Wythenshawe and Chorlton, Manchester, UK. By paying attention to how young people's drinking practices and experiences are bound up with relationships with friends, family, and diverse spaces, this research enhances understandings of the relational nature of young people's alcohol-related transitions to adulthood. Theoretically, I work at the intersection of multiple more-than-representational conceptual apparatus: 'doing' friendship; mobilities; and atmospheres. I conducted this research with young people, using a flexible suite of methods, which they could 'opt into', including: interviews; peer interviews; drawing elicitation interviews; diaries; mobile phone methods; and participant observation. Young people detail how alcohol assists with the formation of friendships, tensions between friends and strangers, and the development of 'more-than-friendships'. I thus contribute to the children's geographies literature by affording the role of friendship to many young people's everynight lives greater prominence. Second, by engaging with young people's emotional and embodied walking and vehicular mobilities, I show that young people consume alcohol on the move because it is both economically beneficial, and emotionally important. In doing so, I move beyond the typical academic and policy treatment of drinking spaces as bounded terrains. Third, I engage with young people's atmospheric experiences of darkness and lightness. I argue that atmospheres have the ability to shape drinking practices and experiences; young people are not passive to these atmospheres, they actively co-construct them. Whilst traditional harm-reduction messages focus on the individual drinker, I urge policymakers to turn their attention to intra and intergenerational relationships. For instance, by encouraging the practice of being a 'good friend' on nights in/out involving alcohol; and by providing families with advice on how to construct positive affective drinking atmospheres.

The Bakkie Brigade in Cape Town’s urban waste economy: exploring waste mobilities and the precariat

Goeiman, Johnathan January 2020 (has links)
Magister Artium - MA / Solid waste management in South Africa is in a phase of transitioning. This transition entails the valorisation and diversion of recyclable waste away from landfills for the creation of a new secondary recycling economy. However, reclaimers within the Global South have been engaged in valorising waste through market-driven pricing. Localised and ‘informal’ as they are, they remain a significant source of labour for global capital. Their presence runs parallel to the emergence of green models such as the circular economy, coupled with contentious initiatives that aim at formalising and integrating reclaimers. Given the revitalised emphasis on the urban waste economy, inadequate attention has been given to understanding the linkages between the formal processing companies and informal waste reclaimers operating at the level of the street and landfill.

Studies on Fraction I Protein

Wilson, Jack Harold 04 1900 (has links)
<p> Studies on the isolation and purification of Fraction I protein from various plants are described. Clear differences in the electrophoretic mobilities of Fr I from various species were observed. The genetic implication of observations on the electrophoretic mobilities of Fr I from wheat, rye and triticales are discussed. It is suggested that a non-chromosomal gene codes for Fr I. Conclusions are drawn from the fingerprint, N-terminal amino acid, and amino acid analysis studies. The presence of ribulose diphosphate carboxylase activity in Fr I protein is also investigated.</p> / Thesis / Doctor of Philosophy (PhD)
