Reflections on Hindi and history

Pace, Colin Gaylon 02 October 2014 (has links)
In this paper, I consider historical periods, linguistic categories, and social theories in relation to Hindi in order to trace out the character and trajectory of the language. From sixteenth-century courtly contexts, to the adoption of the Devanagari script in the twentieth century by nationalists, Hindi has a polyvalent and yet specific history. I discuss these contexts in which social contact led to linguistic change and in which Hindi acquired many of the lexical, syntactical, and phonological characteristics by which it is recognized today. I conclude with a section that considers the motif of language and power, and I suggest that the production of knowledge and power in language use, offers both the means of distinction and expression or, in another sense, of hierarchy and communitas. A thread that runs throughout the paper is attention to the contexts in which language use enables elaboration and in which elaboration is eschewed in order to attain social unity. Pursuing a descriptive historical-linguistic project, I neither affirm nor deny the politics of such language use, but rather I indicate the ways in which actors and agents use Hindi to help articulate their agency. / text

Categorical model structures

Williamson, Richard David January 2011 (has links)
We build a model structure from the simple point of departure of a structured interval in a monoidal category — more generally, a structured cylinder and a structured co-cylinder in a category.

White Female Schoolteachers Perceptions and Experiences with HIV/AIDS

De Kock, Lauren 17 November 2006 (has links)
Student Number : 0205732P - MA research report - Faculty of Humanities / In the only national study of HIV/AIDS prevalence rates in South Africa, using racial groups as categories of analysis, it was found that 6.2% of White South Africans are HIV positive (Nelson Mandela/HSRC, 2002). This prevalence is higher than in ‘White’ populations in other countries (Nelson Mandela/HSRC, 2002). This high prevalence rate amongst white South Africans, though researched and published, appears to be unknown amongst white schoolteachers. Those armed with this knowledge, the media and prevention campaigns, seem to perpetuate the stereotypical image that HIV/AIDS is a ‘Black’ disease. This perception, evident amongst the schoolteachers interviewed, seems to stem from the personal experiences that the teachers have had, the social encounters experienced, as well as the prejudices created about Black people throughout colonial and apartheid times. Promiscuity is considered as the number one reason why the spread of HIV/AIDS has been so rampant in South Africa. Therefore, Black people are not only perceived as being promiscuous, but HIV positive. Due to the fact that respondents seem to make a natural connection between HIV/AIDS and race, emphasis must be placed on White South Africans, in order to aid in the dispelling of false and potentially fatal misconceptions. A false sense of security does exist amongst the white schoolteachers interviewed. A large majority did not perceive themselves, their family or friends, as being at risk of HIV/AIDS infection. However, cognizance must be taken of the fact that this perception has not merely been thought up at random, it is the product of a racialized past.

Weakly integrally closed domains and forbidden patterns

Unknown Date (has links)
An integral domain D is weakly integrally closed if whenever there is an element x in the quotient field of D and a nonzero finitely generated ideal J of D such that xJ J2, then x is in D. We define weakly integrally closed numerical monoids similarly. If a monoid algebra is weakly integrally closed, then so is the monoid. A pattern F of finitely many 0's and 1's is forbidden if whenever the characteristic binary string of a numerical monoid M contains F, then M is not weakly integrally closed. Any stretch of the pattern 11011 is forbidden. A numerical monoid M is weakly integrally closed if and only if it has a forbidden pattern. For every finite set S of forbidden patterns, there exists a monoid that is not weakly integrally closed and that contains no stretch of a pattern in S. It is shown that particular monoid algebras are weakly integrally closed. / by Mary E.

The comparison of treatments with ordinal responses. / CUHK electronic theses & dissertations collection

January 2011 (has links)
In this thesis, we focus on the the comparison of treatments with ordered categorical responses. The three cases of treatment comparisons will all be studied. The main objective of this thesis is to develop more effective comparison methods for treatments with ordinal responses and to address some important issues involved in different comparison problems. Our major statistical approach is to consider ordinal responses as manifestations of some underlying continuous random variables. / The comparison of treatments to detect possible treatment effects is a very important topic in statistical research. It has been drawing significant interests from both academicians and practitioners. Important research work on treatment comparisons dates back several decades. For treatment comparisons, the following three cases are very common: the comparison of two independent treatments; the comparison of treatments with repeated measurements; and the multiple comparison of several treatments. For different cases, the involved research issues are usually different. In many fields of study, the level of measurement for responses of the treatments is ordinal. Many examples can be found in areas such as biostatistics, psychology, sociology, and market research, where the ordered categorical variables play an important role. / This thesis consists of three main parts. In the first part, we consider the modeling of treatments with longitudinal ordinal responses by a latent growth curve. On the basis of such a latent growth curve, we achieve a comprehensive flexible model with straightforward interpretations and a variety of applications including treatment comparison, the analysis of covariates, and equivalence test of treatments. In the second part, we consider the comparison of several treatments with a control for ordinal responses. By considering the ordinal responses as manifestations of some underlying normal random variables, a latent normal distribution model is utilized and the corresponding parameter estimation method is proposed. Further, we also derive testing procedures that compare several treatments with a control under an analytical framework. Both single-step and stepwise procedures are introduced, and these procedures are compared in terms of average power based on a simulation study. In the last part of this thesis, we establish a unified framework for treatment comparisons with ordinal responses, which allows various treatment comparison methods be comprehended using a unified perspective. The latent variable model is also utilized, but the underlying random variables are allowed to have any member of the location-scale distribution family. This latent variable model under such a specification of underlying distributions subsumes many existing models in the literature. A two-step procedure to identify the model and produce the parameter estimates is proposed. Based on this procedure, many important statistical inferences can be conveniently conducted. Furthermore, the sample size determination method based on the latent variable method is also proposed. The proposed latent variable method is compared with the existing methods in terms of power and sample size. / Lu, Tongyu. / Adviser: Wai-Yin Poon. / Source: Dissertation Abstracts International, Volume: 73-06, Section: B, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2011. / Includes bibliographical references (leaves 94-101). / Electronic reproduction.

Derived Categories of Moduli Spaces of Semistable Pairs over Curves

Potashnik, Natasha January 2016 (has links)
The context of this thesis is derived categories in algebraic geometry and geo- metric quotients. Specifically, we prove the embedding of the derived category of a smooth curve of genus greater than one into the derived category of the moduli space of semistable pairs over the curve. We also describe closed cover conditions under which the composition of a pullback and a pushforward induces a fully faithful functor. To prove our main result, we give an exposition of how to think of general Geometric Invariant Theory quotients as quotients by the multiplicative group.

Mothers' and fathers' perceptions of the family context and children's adjustment : coparenting young twins

Latham, Rachel M. January 2017 (has links)
Mothers' and fathers' perceptions of the quality of coparenting – the way in which they work together in their role as parents – forms the focus of three papers that comprise this thesis. Using a novel sample of ‘intact' families with young twins, this research extends the existing coparenting literature beyond its typical focus on first-born children, to include more complex families. Participants were families who were part of the Twins, Family and Behaviour (TFaB) Study, a longitudinal, multimethod study of UK families with twins born in 2009/10 conducted by myself and my colleague over a two-year period. Paper 1 examines bidirectional associations between coparenting and the marital relationship during the transition-to-school period. Controlling for cross-sectional associations and temporal stability, parents' perceptions of higher quality coparenting were associated with their subsequent report of a higher quality marital relationship. Reciprocal associations between the marital relationship and subsequent coparenting, however, were not evidenced. These findings highlight the salience of coparenting for the marital relationship, and suggest that interventions seeking to improve the couples' marital relationship should pay close attention to their coparenting. Paper 2 focuses on parenting sense of competence (PSOC), examining the role of children's disruptive behaviour, coparenting, and their interaction. For both mothers and fathers there was a significant interaction between their perceptions of coparenting and children's disruptive behaviour such that high quality coparenting may protect the PSOC of parents dealing with high levels of children's disruptive behaviour. These findings imply that practitioners and interventions concerned with promoting PSOC should pay due attention to the quality of coparenting as an important family context. Paper 3 examines family-wide and child-specific effects of coparenting and coercive parenting on the development of children's disruptive behaviour. Mothers' perceptions of coparenting interacted with maternal overall coercive parenting such that high quality coparenting intensified the toxicity of maternal coercive parenting for children's disruptive behaviour. This novel – and unexpected – finding indicates that the influence of high quality coparenting is not necessarily always positive. Coparenting interventions aiming to improve child outcomes would therefore be well-advised to also consider parenting strategies. Further research is encouraged to explore these research questions within samples of socioeconomic diversity and across family types, as well as studies designed to examine twin and non-twin family differences.
