Topics on z-ideals of commutative ringsTlharesakgosi, Batsile 02 1900 (has links)
The first few chapters of the dissertation will catalogue what is known regarding z-ideals in
commutative rings with identity. Some special attention will be paid to z-ideals in function
rings to show how the presence of the topological description simplifies z-covers of arbitrary
ideals. Conditions in an f-ring that ensure that the sum of z-ideals is a z-ideal will be given.
In the latter part of the dissertation I will generalise a result in higher order z-ideals and
introduce a notion of higher order d-ideals / Mathematical Sciences / M. Sc. (Mathematics)

Neurale netwerke as moontlike woordafkappingstegniek vir AfrikaansFick, Machteld 09 1900 (has links)
Text in Afrikaans / Summaries in Afrikaans and English / In Afrikaans, soos in NederJands en Duits, word saamgestelde woorde aanmekaar geskryf. Nuwe
woorde word dus voortdurend geskep deur woorde aanmekaar te haak Dit bemoeilik die proses
van woordafkapping tydens teksprosessering, wat deesdae deur rekenaars gedoen word, aangesien
die verwysingsbron gedurig verander. Daar bestaan verskeie afkappingsalgoritmes en tegnieke, maar
die resultate is onbevredigend. Afrikaanse woorde met korrekte lettergreepverdeling is net die elektroniese
weergawe van die handwoordeboek van die Afrikaanse Taal (HAT) onttrek. 'n Neutrale
netwerk ( vorentoevoer-terugpropagering) is met sowat. 5 000 van hierdie woorde afgerig. Die neurale
netwerk is verfyn deur 'n gcskikte afrigtingsalgoritme en oorfragfunksie vir die probleem asook die
optimale aantal verborge lae en aantal neurone in elke laag te bepaal. Die neurale netwerk is met
5 000 nuwe woorde getoets en dit het 97,56% van moontlike posisies korrek as of geldige of ongeldige
afkappingsposisies geklassifiseer. Verder is 510 woorde uit tydskrifartikels met die neurale netwerk
getoets en 98,75% van moontlike posisies is korrek geklassifiseer. / In Afrikaans, like in Dutch and German, compound words are written as one word. New words are
therefore created by simply joining words. Word hyphenation during typesetting by computer is a
problem, because the source of reference changes all the time. Several algorithms and techniques
for hyphenation exist, but results are not satisfactory. Afrikaans words with correct syllabification
were extracted from the electronic version of the Handwoordeboek van die Afrikaans Taal (HAT).
A neural network (feedforward backpropagation) was trained with about 5 000 of these words. The
neural network was refined by heuristically finding a suitable training algorithm and transfer function
for the problem as well as determining the optimal number of layers and number of neurons in each
layer. The neural network was tested with 5 000 words not the training data. It classified 97,56% of
possible points in these words correctly as either valid or invalid hyphenation points. Furthermore,
510 words from articles in a magazine were tested with the neural network and 98,75% of possible
positions were classified correctly. / Computing / M.Sc. (Operasionele Navorsing)

The exodus of Baptist pastorsPierce, Stephen Brian 11 1900 (has links)
The goal of the research was to explore the ongoing problem of Baptist Pastors leaving the ministry and to attempt to discover the impact of this problem upon Baptist Churches by means of
"focus group" interviews. The dissertation links the problem with a Baptist ecclesiology and seeks to understand the Baptist belief in the autonomy of the Local Church and the praxis of accreditation for pastoral ministry, plus the existence of so-called "subterranean Pastors" which has contributed toward pastoral termination. / Practical theology / M.Th.

Psychological effects of the termination of pregnancy by choice on adolescentsSebola, Botshelo Rachel 11 1900 (has links)
The aim of this study was to explore the psychological effects of termination of pregnancy by choice amongst adolescents within the ages of 18 to 21 years.
Exploratory, contextual, qualitative design was used to determine the psychological effects of termination of pregnancy by choice amongst adolescents. Purposive sampling method as well as snowballing were used to select participants for the study.
Data collection was done through in-depth, one-on-one, face-to-face interviews, using a semi-structured interview guide.
The study highlighted that adolescents who seek abortion are unmarried and mostly still studying.
The results revealed that adolescents experience mental ill health after termination of pregnancy due to feelings of guilt. All participants stated that abortion is murder of a life person and that it is a bad thing to do.
The study revealed that counselling that is done before TOP focuses on the procedure of TOP. There is need for a holistic approach to counselling.
As a guide, policy makers need to specify the mandatory counselling in the Choice on
Termination of Pregnancy Act (Act No 92 of 1996). / Health Studies / M.A. (Nursing Science)

Os contratos que viabilizam o processo de distribuição e os efeitos de sua denúncia unilateral / The contracts types that enable the economic process distribution and the effects of the unilateral terminationAndré Brandão Nery Costa 02 September 2014 (has links)
Trata-se de dissertação elaborada com o escopo de identificar os efeitos da denúncia unilateral exercida no âmbito dos tipos contratuais instrumentalizados ao processo de distribuição de bens e serviços, a partir do exame das diferenças tipológicas entre cada um deles. Aludidos tipos contratuais correspondem ao de agência, de representação comercial autônoma, de concessão comercial e de franquia, cujos contornos ainda são frutos de intenso debate doutrinário. No ordenamento pátrio, enquanto alguns tipos contratuais não sofreram regulamentação legal, outros tais como o de agência, de representação comercial autônoma, de concessão comercial de veículos autores e de franquia são regulados legislativamente, em fenômeno a que não se assiste em nenhum outro ordenamento da família romano-germânica. A construção da disciplina de tais consequências jurídicas transpassa pela delimitação do âmbito de incidência de cada um desses regimes legais, os quais podem atribuir consequências jurídicas próprias. Os tipos de agência e de representação comercial são equivalentes, o que permite tratá-lo de maneira conjunta, enquanto aqueles de concessão comercial e de franquia, a despeito de apresentarem diferenças relevantes, também podem ser examinados em conjunto pela similar estruturação dos interesses, a despeito de apresentarem peculiares leis regulando-os. Após realizado o exame legislativo e tipológico, examinou-se o impacto do princípio da boa-fé objetiva na determinação dos efeitos desencadeados pela resilição unilateral exercida pelo produtor nos contratos por tempo indeterminado, assim como a influência da previsão do parágrafo único do art. 473 do Código Civil na delimitação desses corolários jurídicos no que tange aos tipos contratuais analisados. Realizado essa investigação, constatou-se que, conquanto existam inúmeros fatores que distanciem, de um lado, os tipos de agência e de representação comercial autônoma e, de outro, de concessão comercial e de franquia, os efeitos desencadeados pela denúncia unilateral são semelhantes, próximos àqueles das relações de duração e nas quais existe estreita confiança. / This dissertation aims to identify the effects of unilateral termination of contractual types exploited under the economic process of distribution of goods and services, from the examination of typological differences between each of these contracts. Alluded contractual types correspond to the agência, representação comercial autônoma, concessão comercial and franquia, which contours are still fruit of intense doctrinal debate. In the Brazilian legal system, while some contractual types suffered no legal regulation, others such as agência, representação comercial autônoma, concessão comercial de veículos automotores and franquia are regulated legislatively, in a phenomenon that it is not witnessed in any other roman-germanic legal system. The construction of the discipline of such legal consequences pierces the scoping incidence of each of these statutory schemes, which may assign legal consequences of their own. It was found that the types of agência and concessão comercial are equivalent, allowing to treat them jointly, while those of concessão comercial and franquia, despite presenting relevant differences, can also be examined jointly as they present a similar structure of interests, despite presenting peculiar laws regulating them. After the legislation and typological examination, it was examined the impact of the principle of good faith in determining the effects triggered by the notice to quit of the producer in contracts for an indefinite period, as well as the determining influence of the sole paragraph of article 473 of the Brazilian Civil Code in the legal definition of these corollaries with respect to the contractual types analyzed. It was found that while there are numerous factors that distance themselves the effects triggered by unilateral withdrawal are similar and close to those of the contracts relational contracts.

How can the rights of paying consumers to electricity be squared with the rights of Eskom to be paid?'Wyngaard, Lisa Jade January 2018 (has links)
Magister Legum - LLM (Public Law and Jurisprudence) / Electricity supply can be classified into three stages namely: generation, transmission and distribution, with the functions of generation and transmission being carried out by Eskom. In 2001, Eskom was converted from a statutory body into a public company having a share capital with its entire share capital held by the State. It is a major public entity and therefore an Organ of State and albeit that Eskom is classified as a public company, it is still a State-owned Enterprise. Municipalities purchase electricity from Eskom in bulk in order to carry out the distribution function and manage bulk supply of electricity to end-users in terms of the Local Government: Municipal Structures Act 117 of 1998 (Structures Act). Municipalities re-sell electricity purchased from Eskom to end-users as well as provide free basic electricity to indigent consumers.

Encouraging individual retirement savings in South AfricaHirschbeck, Lisa January 2015 (has links)
Many South Africans may not have adequate retirement savings when they retire and this has the effect of a low income replacement ratio on retirement that may lead to a decrease in the standard of living of the retiree and in extreme cases the retiree becoming dependent on their family and the government. Owing to this trend of no or inadequate retirement savings, South Africa embarked on a retirement reform journey in 2004. The goal of this research is to determine whether the retirement reform mechanisms outlined by National Treasury would encourage individual retirement savings that should assist South Africans to achieve stability of income in their retirement. This research analysed the current retirement savings options and vehicles available for South Africans, the current tax incentives and disincentives and reviewed the proposed changes to tax incentives and disincentives during the accumulation phase of retirement savings and explained how these proposed tax incentives are harmonised for the accumulation phase of retirement. The research explained how National Treasury aims to limit pre-retirement withdrawals and how it intends to encourage the annuitisation of post-retirement benefits. The penultimate chapter of this research measured the effect (by making certain assumptions) of the changes proposed by National Treasury on the income replacement ratio of the retiree. Throughout the research comparisons were made between The OECD Roadmap for the good design of defined contribution pension plans and National Treasury’s proposals. This research did not directly address the effect of increased life expectancies on retirement savings or increases in youth unemployment and the effect that this may have on retirement savings. The effect of financial charges levied on retirement savings on the income replacement ratio of a retiree was also not explored. Furthermore, not all pension funds are regulated by the Pension Funds Act and how these pension funds can be brought within the purview of the Pension Funds Act was not investigated. Automatic enrolment of retirement savings for all employees in South Africa in retirement vehicles is a further research area that could be addressed.

Les relations d'affaires : approche comparée du droit français et du droit libanais / The business relations : comparative approach between the French law and the Lebanese lawMouawad, Julie 26 January 2018 (has links)
Le mot « relations d’affaires » n’est plus seulement une simple dénomination dans le « monde du business » ; en effet, la notion juridique de relations d’affaires intervient aujourd’hui comme étant une nouvelle catégorie juridique du droit notamment depuis la rédaction de l’ordonnance française n⁰ 2016-131 du 10 février 2016. Notre analyse va porter sur la consécration de la notion de relations d’affaires en droit positif français et libanais. Cette analyse aura pour intérêt principal de tenter d’esquisser une définition générale de la notion de relations d’affaires, de développer le cadre juridique dans lequel elle se forme et de déterminer les caractéristiques relatives à la notion de relations d’affaires. Une approche juridique de cette notion nous permet de préciser les contours du régime juridique de la notion de relations d’affaires tout en se basant, en grande partie, sur l’article L. 442-6-I, 5⁰ du Code de commerce français. L’analyse de l’équilibre économique et de la sécurité juridique des contractants va conduire à étudier non seulement les relations pré-contractuelles et contractuelles mais aussi le sort et les effets juridiques des relations d’affaires au stade post contractuel. On s’attachera dans une première approche, à éclaircir les domaines dans lesquels la notion de relations d’affaires est abordée en droit positif et essayer d’en préciser les éléments constitutifs. Et dans une deuxième approche, on analysera les effets juridiques de la notion de relations d’affaires au cours des diverses phases de la formation du contrat et des conséquences de la rupture du contrat sur lesdites relations / The word « business relations » is no longer only a denomination in the « business world »; in fact, the legal notion of business relations intervenes today as a new legal category of law, in particular since the drafting of French order No. 2016-131 in 10 February 2016. Our analysis will focus on the consecration of « business relations » in French and Lebanese positive law. This analysis has a principal interest to attempt to outline a general definition of the concept of « business relations », to develop the legal framework within which it is formed, and to determine the related characteristics of the business relations concept. A legal approach of this notion has enabled us to specify the legal framework of the business relations notion, this is largely based on article L. 442-6-I, 5⁰ of the French commercial code. The analysis of the economic equilibrium and the legal security of contractors will lead us to study not only the pre-contractual and contractual relations but also the condition and the legal effects of business relations at the post-contract stage. In a first approach, we will clarify the areas in which the notion of business relations is approached in positive law, and will try to specify its constituent elements. In a second approach, we will analyze the legal effects of the « business relations » notion during the diverse phases of the contract drafting and the consequences of the contract termination on those relations

Vnímání zdravotních pojišťoven v Jihočeském kraji / Perception of health insurance companies in the South Bohemian RegionHYKOVÁ, Michaela January 2010 (has links)
In my thesis, I deal with the issue of perception of health insurance companies in the South Bohemian Region. That is, how South Bohemian citizens perceive health insurance companies and whether they are satisfied with the services that health insurance companies provide. In the theoretical part, I present basic information about public health insurance system in the Czech Republic. I mention the history of health insurance evolution, its systems, and principles of its operation. I also deal with legislature which is the cornerstone of this system. Most of the laws were passed in the 1990?s when the Czech Republic began to develop the current version of health insurance. Since its inception, these laws have been amended several times. Public health insurance system in our country is based on the Bismarck model, which is based on the existence of multiple health insurance companies and contractual relationships between health insurance companies and health care facilities. Furthermore, the theoretical part refers about health insurance companies as such, whose activities are governed by Act No. 551/1991 Coll., on the General Health Insurance Company, and Act No. 280/1992 Coll., on departmental, professional, occupational and other health insurance companies. The practical part describes the results of my research focused on the aforementioned issue of perception of health insurance companies in the South Bohemian Region. The results have been obtained through quantitative analysis. The method of questioning, the technique of questionnaires, was used. In this research, two of three assumed hypotheses have been confirmed. The research shows that health insurance clients in the South Bohemian Region are satisfied with local and time availability of their health insurance company subsidiaries. Furthermore, the research carried out shows that citizens respect the opinion of their general practitioners on the selection of their health insurance company. In contrast, what good (preventive) programs health insurance companies offer is not crucial for citizens when selecting a health insurance company. The knowledge gained can form the basis for further research, but it can also serve to health insurance companies themselves to improve their services. The issue of health care and health insurance companies is still a topic of current concern, both in the political field and for the general public.
