Les technologies de l’information et de la communication (TIC) ont massivement introduit les modes de vie et envahi le quotidien. Leur utilisation et leur présence dans notre société constituent désormais un fait incontesté. Cette recherche présente un travail d’analyse statistique réalisé à partir des microdonnées des enquêtes des dépenses des ménages de Statistique Canada. Dans un premier temps, nous proposons une typologie qui permet de cerner l’univers des TIC qui nous intéresse. Nous présentons ensuite un portrait de la consommation des technologies de l’information et de la communication au sein de la structure des dépenses des ménages au Québec et une analyse en fonction de certaines caractéristiques socio-économiques. Un portrait des dépenses selon différents types de TIC est également exposé dans le but de faire ressortir les tendances de consommation entre la dépense de biens et de services.

Étant donné que les dépenses de consommation comptent pour environ 60 % du PIB au Québec, il est primordial de comprendre comment les politiques économiques affectent la demande agrégée via les dépenses de consommation des ménages et aussi, comment les dépenses de consommation seront affectées selon l’environnement des consommateurs. En premier lieu, ce mémoire modélise la consommation avec une technique économétrique qui ne repose pas sur l’hypothèse d’une structure de préférence particulière. Dans un deuxième temps, ce mémoire estime un modèle d’agent économique rationnel optimisateur face au problème de l’allocation intertemporelle de sa consommation de biens durables et non durables quand les fluctuations des taux d’intérêt canadiennes varient. La période étudiée est de 1981 à 2011. Nos résultats correspondent à ce qui est généralement observé dans la littérature et nous ont permis de mettre en évidence le rôle joué par le revenu, le prix relatif des biens durables, la richesse financière, la valeur des maisons, la confiance des ménages et les fluctuations des taux d’intérêt pour expliquer les variations des dépenses de consommation des ménages québécois dans son ensemble, mais aussi selon certaines sous-catégories. Notre analyse nous a également permis de constater qu’en désagrégeant la consommation des ménages québécois, il est important de tenir compte des liens entre ses sous-catégories. La non-séparabilité au niveau des préférences entre les biens durables et non durables est importante et c’est pourquoi il est préférable d’en tenir compte dans la modélisation des différentes catégories de la consommation agrégée. / Due to the fact that the household consumption expenditure are valued for approximately 60% of Quebec's GDP, it is important to understand how economic politics affect the aggregate demand through consumers' expenses and also, how household consumption expenditures will vary according to the consumer's environment. Firstly, this paper reviews the consumption with an econometric technique of no particular structure. Secondly, this paper proposes and estimates a model of an optimizing agent who is faced with the problem of allocating intertemporally his consumption of non-durable and durable goods when confronted with a fluctuating rate of return. Expectations are assumed to be formed rationally. The study was conducted from 1981(01) to 2011(03). Our results are consistent with the findings of previous studies and the literature and allowed us to interpret how income, relative price of durable goods, financial wealth, housing market, index of consumer confidence, and interest fluctuations could explain the variation in consumption expenditures of households in Quebec as a whole, but also by some sub-categories. Our analysis also revealed that when household consumption is disaggregated, it is important to consider the relationship between those sub-categories. Non-separability in preferences between durables and non-durables is important and this is why the modeling of different types of aggregate consumption should be taken into consideration.

The rapid increase in the expenditure on below-the-line promotions (consumer and trade promotions, direct marketing, sponsorship and public relations) relative to above-the-line advertising (television, radio, print, outdoor and cinema) in South Africa has earmarked a new era of integrated marketing communication strategies across all sectors. Ultimately, this strategic shift has brought about a need to better understand the relationship between above-the-line advertising and below-the-line promotions and to measure the impact of such changes on company sales/profits over the long-term. In the research undertaken amongst 250 senior marketing, brand and product managers of South African brand-owned companies, the relationship between above-the-line advertising and below-the-line promotions in the marketing of South African products and services was investigated across six different economic sectors. It was evident from the findings that most brand-owned companies currently integrate above-the-line advertising and below-the-line promotion activities. The study shows that most brand-owned companies in South Africa combine press, radio and television (above-the-line) with consumer promotions (below-the-line). The most frequently used above-the-line advertising medium is television, which is also seen as the most important mode to support long-term brand building amongst consumers. In turn, print is regarded as the most important above-the-line mode to support trade franchise building. Most frequently used below-the-line modes include direct marketing and public relations. Direct mail and cooperative advertising are seen as the most important below-the-line consumer and trade franchise building modes respectively. Although marketing communication expenditure is positively skewed towards above-the-line adverstising, most recent trends show a gradual increase in the use of below-the-line promotions. To prevent a brand's sales/profits from decreasing over the long-term due to too high below-the-line promotional expenditure, the study encourages a sound balance between above-the-line advertising and below-the-line promotions. Although the ideal ratio of above-the-line advertising to below-the-line promotions is related to the nature of the product and service being marketed, the extent of competitive activity in the market and the frequency of purchase, amongst many other salient factors, the study regards a 60/40 ratio as the most ideal for building long-term brands. On the other hand, a ratio of 35/65 is regarded as the critical point at which company sales/profits may deteriorate because of too high below-the-line promotional spending. In conclusion it can be said that the marketing communication industry of South Africa has entered a period of integrated marketing communication practices which requires sound marketing communication budget strategies conducive to the long-term survival of South African products and services. / Business Management / D.

This study examines the efficacy of collection development and management practices, policies, guidelines and standards in universities of technology to meet the information needs of academics and researchers at such institutions. In South Africa, as in Australasia, technikons or polytechnics have been upgraded first into degree granting institutions and then, at the beginning of the 21st century, into universities of technology. The researcher was concerned that library collections in South African universities of technology have not grown to meet the research and teaching needs of academics at the level of universities offering instruction up to a doctoral level. As research funding, government grants and the general prestige of the institutions depend on the research output of the institutions, it is essential that academics and researchers find the information resources they require in their institutional libraries. Case studies of universities of technology in New Zealand and South Africa reveal that, while Auckland University of Technology has been successful in extending its collection to meet the increasing demands placed on it, the collection development policies, standards and guidelines in a South African university of technology need to be upgraded in order to meet the information needs and information behaviour of their researchers and academics. Current levels of funding for the acquisition of information resources in South Africa lag behind those found at the New Zealand university of technology. The university of technology that was the object of the South African case study needs to bring its collection in line with that of similar institutions worldwide. This entails adapting goals and objectives stating how the collection is to develop, evaluating the collection and the needs of users, changing the Collection Development Policy to reflect the direction collection development will take and ensuring that the institution and the government back this project financially. To this end, a model Collection Development Policy has been drawn up that can be adapted to the local requirements of South African universities of technology to assist with the process of developing and managing library collections that will be worthy of such an institution. / Information Science / D.

This research focuses on problems encountered by School Governing Bodies (SGBs) in executing their financial task in four schools situated in the Ramotse Area, Hammanskraal, north-east of the city of Tshwane. The research methodology, which was employed, can be described as qualitative, exploratory and descriptive by nature. Data was collected by means of two focus group interviews, one involving the chairpersons of SGBs and the other involving the managers of the same schools. An analysis of the data has revealed a number of financially related problems, which SGBs in the Ramotse Area experience, amongst other things that parents fail to meet their financial obligations and subsidies tend to arrive late. The most important recommendation made is that SGBs should be trained both better and more frequently. / Educational Studies / M. Ed. (Education Management)

In South Africa household debt has increased rapidly over the past few years, therefore illustrating the importance of analysing liability usage behaviour of individual members within the household. In order to comprehend the behaviour of South Africans regarding liability usages, this study provides insight into why individuals find it necessary to obtain liability products as well as to indicate whether liability products are used to address the financial needs for the purpose it was developed for. To achieve the aim of this study, it was firstly necessary to develop a theoretical framework for the process of selecting credit products when satisfying financial needs. Secondly, the characteristics and intended usage purposes of different credit products available in South Africa were discussed and a debt classification framework was developed. Finally, data obtained from the Finscope South Africa survey was analysed according to the developed frameworks following a combination of two approaches. Firstly, a qualitative approach was used to identify the different financial needs which are satisfied when using liabilities. The financial needs identified were classified according to Alderfer’s existence relatedness growth (ERG) theory and the factors that have an influence on liability usage. Secondly, a quantitative approach was followed to indicate which financial needs are fulfilled when using different credit products. The results of this study suggest that individuals do not use liabilities only for the purpose what the products were originally developed for. The findings clearly indicated that individuals mainly use liabilities to satisfy basic needs which are classified as existence needs according to Alderfer’s ERG theory. Based on the data analysis a variety of factors such as access to credit and certain demographic characteristics have an influence on liability usage behaviour of individuals. The results further show that individuals mainly use informal, unsecured, short-term loans when satisfying their financial needs which might indicate that South Africans are unable to access formal credit products. / Financial Accounting / M.

This dissertation consists of three empirical essays investigating different aspects of health care for children and families. The first essay examines the effectiveness of adherence to American Academy of Pediatrics guidelines for preventive pediatric health care. Using a national longitudinal sample of children age two years and younger, we investigate whether compliance with prescribed periodic well-child care visits has beneficial effects on child health. We find that increased compliance improves child health. In particular, higher compliance lowers future risks of fair or poor health, of some history of a serious illness and of having a health limitation. The second essay examines child health care utilization in relation to maternal labor supply. We test the hypothesis that working-mothers trade off the advantages of greater income against the disadvantages of less time for other valuable tasks, such as seeking health care for their children. This tradeoff may result in positive, negative, or no net impacts on child health investment. We estimate health care demand regressions that include separate variables for mother’s labor supply and her labor income. Our results indicate that higher maternal work hours reduce child health care visits; higher maternal earnings increase them. In addition, wage-employment, as opposed to self-employment, is detrimental to child health investment. A further finding is that preventive care demand for younger children is less sensitive to maternal time and income changes. We also find that detrimental time effects dominate beneficial income effects. The third essay studies intra-household resource allocation as it pertains to its demand for preventive medical care. We test the income-pooling hypothesis of the common preference model by using individual specific medical care consumption data and present evidence on the allocation of household resources to the medical needs of the child, husband and wife. Our results are in line with the findings of previous studies that emphasize the ongoing importance of the traditional gender role of woman as the primary caregiver. We find that the resources of the wife have a greater positive impact on child’s and her own preventive care demand than does the resources of the husband. In contrast to most studies from developing countries, we find that US families do not exhibit differential health care demand based on child gender. It is also noteworthy that the wife’s education level has a greater positive impact than that of her husband does on both the husband’s and her own preventive care utilization. / text
