Gender social networks and income generation among Congolese migrants in Johannesburg

Monche, Felix 16 February 2007 (has links)
Student Number : 0517437P - MA dissertation - Graduate School of Humanities and Social Sciences - Faculty of Humanities / A significant number of refugees and asylum seekers are living in urban areas in developing countries. In addition to the fact that they receive little assistance from international organizations, host government policies represent obstacles to their livelihoods. Generally, the economic behaviour, reasons for migrating and experiences of female migrants often differ from those of male. This research report examines the impact of gender on social networks and how gender might influence access to income. In contrast to other studies on social networks that focus on the social relationships between individuals and communities located in sending and receiving societies, this study produces greater understanding of urban migrants’ livelihoods by exploring how women use social networks to generate income and contrasting these with those of men. This is rooted in the assumption that women refugees are facing additional challenges to livelihood including their social responsibilities and job stereotyping. To document how gender might influence social networks and access to income, qualitative data collected through semi structured, face-to-face, in-depth interviews among Congolese refugees in Johannesburg was used. Findings reveal that gender does not have impact on the nature of social networks used by Congolese men and women to facilitate their access to income generating activities. However, friendships and social relations among Congolese refugees are based on gender and as a result Congolese refugees may be channelled in gender-dominated occupations. Congolese women are facing specific challenges such as domestic labour and child care that may limit their access to jobs and businesses.

Multivariate finite operator calculus applied to counting ballot paths containing patterns [electronic resource]

Unknown Date (has links)
Counting lattice paths where the number of occurrences of a given pattern is monitored requires a careful analysis of the pattern. Not the length, but the characteristics of the pattern are responsible for the difficulties in finding explicit solutions. Certain features, like overlap and difference in number of ! and " steps determine the recursion formula. In the case of ballot paths, that is paths the stay weakly above the line y = x, the solutions to the recursions are typically polynomial sequences. The objects of Finite Operator Calculus are polynomial sequences, thus the theory can be used to solve the recursions. The theory of Finite Operator Calculus is strengthened and extended to the multivariate setting in order to obtain solutions, and to prepare for future applications. / by Shaun Sullivan. / Thesis (Ph.D.)--Florida Atlantic University, 2011. / Includes bibliography. / Electronic reproduction.

Children as e-designers: how do they understand learning?

McCredie, Nerida Anne January 2007 (has links)
University of Technology, Sydney. Faculty of Education. / This thesis reports an investigation into children's understanding of learning, as they engage with an e-Iearning design challenge. It begins by making a case that children's views of learning are of crucial significance, not only because of their position as pre-eminent learners in families and societies, but also because their learning is at the heart of our culture's aspirations for education. Then, it examines a selection of prior studies of learning in e-design contexts in order to gauge the advantages of seeking the views of children about learning in an e-design context. This consideration revealed the technological and educational potential of e-design, suggesting that such a context would be opportune here. Fortuitously, a large, ARC-funded Linkage Project (GENESIS - Generating e-Iearning Systems in Schools) provided just such an e-design context. In this project, researchers were keen to investigate whether the slowness of schools in appropriating e-Iearning might be offset when students have a sustained opportunity to conceive, design and, as far as possible, build an e-Iearning environment in which they and other students could explore questions they were passionately curious about. As a case study within the GENESIS Project, this study followed Papert's (1973) five-step process of educational research. First, a theory of education (a biologically based generative theory) was selected. Next, the ensuing set of conditions for the intellectual growth of children (the e-Iearning design challenge itself) was laid out. These conditions were then implemented within the context of The GENESIS Project: the children were equipped with the opportunity and resources to design an e-Iearning environment to explore a science-and technology topic of their choice (How and why do we think? How come we're not born with the knowledge we know now?). Of the large set of project data, six accounts were selected as representative of the diversity and commonality of children's learning and their understanding of learning in this study. Findings revealed that these children understand learning as generating, testing and thereby modifying ideas, they appreciate that these events are influenced by each learner's values and they recognise value in undertaking this knowledge gaining activity as part of a learning community. Furthermore, these children explicitly enact opportune learning experiences, particularly technologically, demonstrating their fluency as technological thinkers, capable of having technological ideas about learning.

RR 17 in an economic boom : The impairment procedure of goodwill

Perlinska, Magdalena, Johansen, Johanna January 2009 (has links)
<p>In 2005 a new recommendation was implemented, IAS 36 "Impairment of intangible assets". The Swedish translation of the recommendation is RR 17. The previous treatment of impairment of goodwill was to amortize it over a certain amount of years. In order for a company to make impairment, they had to estimate the decrease in value of goodwill to be permanent. The new recommendation RR 17 on the other hand states that goodwill should be impaired as soon as an indication of impairment loss is revealed. This implies that the new recommendation shows the fair value of goodwill. Our problem description is; <em>how does the impairment procedure of goodwill in companies applying RR 17 look like?</em></p><p>In order to reach the purpose of this study, which is to understand the impairment procedure of goodwill, we used four sub questions; (1) How does goodwill arise? (2) How is goodwill divided between cash generating units?

Character Polynomials and Lagrange Inversion

Rattan, Amarpreet January 2005 (has links)
In this thesis, we investigate two expressions for symmetric group characters: Kerov?s universal character polynomials and Stanley?s character polynomials. We give a new explicit form for Kerov?s polynomials, which exactly evaluate the characters of the symmetric group scaled by degree and a constant. We use this explicit expression to obtain specific information about Kerov polynomials, including partial answers to positivity questions. We then use the expression obtained for Kerov?s polynomials to obtain results about Stanley?s character polynomials.

Distance Spectrum Computation for Generating Signal

Li, Ding-Chien 09 September 2011 (has links)
In this thesis, we compute the distance spectrum for non-causal generating signals and compare the different spectrum effects for different non-causal systems. The non-causal system is the system which the present output is determined by the future and the past. The distance spectrum is the list of the difference measures of any two signals and search through all the possible event paths by trellis as much as possible. We use the method of the line difference to compute the distance spectrum of non-causal generating signal systems by defining the line and the line difference to find the distance for every pair of signals. Using this method, we have computed the distance spectrum for non-causal generating signals. Finally, we compare the different spectrums for different non-causal systems of different coefficients.

Computational and theoretical aspects of iterated generating functions

Clapperton, James Anthony January 2013 (has links)
The thesis offers an investigation into the analysis of so-called iterated generating functions and the schemes that produce them. Beginning with the study of some ad hoc scheme formulations, the notion of an iterated generating function is introduced and a mechanism to produce arbitrary finite sequences established. The development of schemes to accommodate infinite sequences leads – in the case of the Catalan sequence – to the discovery of what are termed Catalan polynomials whose properties are examined. Results are formulated for these polynomials through the algebraic adaptation of classical root-finding algorithms, serving as a basis for the synthesis of new generalised results for other infinite sequences and their associated polynomials.
