Worldwide tourism has become one of the largest and fastest growing industries. Specifically in the South African context, this growth has been confirmed in recent statistics. However, the growth in the tourism industry does not occur without challenges. It brings both benefits and costs to the residents of a host community, consequently generating both positive and negative tourism impacts. Further, it is recognised that once a community becomes a tourism destination, the lives of the residents are influenced by that particular development; thus effecting their Quality of Life (QoL). Only minimal research has, however, been conducted to determine the influence of the perceived impacts of tourism on residents’ QoL, especially in the South African context. A number of theoretical frameworks have been developed in tourism to signify how the perception of or reactions towards tourism of residents in a host community are influenced at any particular stage of development. Pertaining to QoL, various theoretical models have also been created to describe the functioning of the construct. Although theoretical frameworks have been developed that are distinct to tourism and QoL; to date an integrated approach does not exist that explores the influence of tourism on residents’ QoL. In addition to the lack of an integrated approach in literature, the permanency of tourism products too have not yet been examined in literature. Further, permanency has not been examined in order to determine the influence of tourism impacts on residents’ QoL in selected towns, one being a permanent tourism product (PTP) and the other a nonpermanent tourism product (N-PTP). From the above, it can be seen that three theoretical and practical issues exist: (1) only a modest amount of research has been done to determine the influence of tourism impacts on residents’ QoL; (2) an integrated approach does not exist signifying the relationship between tourism impacts and QoL and; (3) permanency as a differentiation factor has not been investigated in host communities. By addressing these issues, a significant contribution will be made to literature, together with the ensuing practical contributions. Therefore, the main goal of the study was to develop a model to indicate the influence of perceived impacts of tourism on residents’ QoL in selected towns; these having specific differentiation made between a PTP and N-PTP. In order to achieve the goal of the study, five objectives were formulated: The first objective was to analyse theoretical frameworks of tourism and QoL and to identify a particular theoretical framework for the study. Specifically, the Social Exchange Theory (SET) was selected from the theoretical frameworks of tourism, while the Bottom-up Spillover theory was designated as it is peculiar to QoL frameworks. Therefore, the derived theoretical framework indicated that an ‘exchange’ process occurs between tourism development and the residents of the host community. More specifically, social exchange arises between the perceived impacts of tourism and life domains in order to establish the QoL of residents in host communities. The second objective was to analyse tourism both as an industry and product in a host community through a review of existing literature. From the literature review, it can be seen that tourism is a growing industry and product, not only internationally but also in the South African context. Permanency as a characteristic was explored comprehensively to define a tourism product while maintaining the differentiation between a PTP and N-PTP. Residents of a host community are noted as important roleplayers in the tourism industry as tourism impacts affect them in PTP and in N-PTP. This importance is emphasised as residents of a host community: (1) influence the tourism experience; (2) determine the attractiveness of a destination and; (3) control the sustainability of tourism in a host community. The third objective was to analyse QoL and its relation to the residents of a host community, once more, through a literature review. From the review, it was observed that QoL has different definitions and views, some more intricate than others. For the purpose of the study, it was determined that QoL can be described appropriately through the Bottom-up Spillover theory. Therefore, QoL is determined through the collaboration of various life domains that, further, may be either objective or subjective in nature. When examining the relationship between tourism development and QoL, it was established that tourism, through tourism products, produces effects that will influence various life domains, consequently determining the QoL of residents in a host community. As with tourism impacts, the QoL of the host community’s residents will subsequently: (1) influence the tourism experience; (2) determine the attractiveness of a destination and; (3) ensure the sustainability of tourism in a community. The fourth objective was to analyse the influence of the economic, environmental, social and cultural impacts of tourism on residents’ QoL and to differentiate between a PTP and N-PTP by using an empirical study. Having in mind that the main goal of the study was to develop a model, Confirmatory Factor Analysis (CFA) and Structural Equation Modelling were conducted on the data. The models, constructed separately for tourism impacts and QoL, were subsequently integrated to determine the influence of the perceived impacts of tourism on residents’ QoL. The model with good model fit statistics and supportive of underlying theory was thereafter accepted for further analysis in order to attain comprehensively the main goal of the study. Thereafter, model development tested permanency of tourism products by specifically determining the influence of perceived impacts of tourism on residents’ QoL in selected towns (PTP and N-PTP). From the latter exercise, no practically significant differences were found between a PTP and N-PTP. Therefore, the model constructed as Stage 3 was accepted as the final model of the study and was given the title of Root’s model of Community TourQoL (CTQ). Specifically, the model signified that positive economic, environmental, social and cultural impacts influence residents’ QoL, while negative environmental and social impacts do not influence residents’ QoL in host community. Furthermore, the model showed that no differences were found between a PTP and N-PTP regarding the influence of perceived impacts of tourism on residents’ QoL. The fifth and final objective was to draw conclusions, indicate contributions, formulate recommendations and present limitations peculiar to the study. The greatest significance of the study is seen in the practical contributions of the study, specifically, the development of Root’s model of Community TourQoL (CTQ). Community and tourism planners and/management can implement the model in both PTP and N-PTP to enhance the positive impacts of tourism; while minimising negative impacts, in order to improve residents’ QoL. / Thesis (PhD (Tourism Management))--North-West University, Potchefstroom Campus, 2013.

The reduction of the impact of energy consumption is a priority issue and a major challenge that concerns every country in the world. This is a complex task that needs to be tackled from several angles in the search for areas where optimizations and savings can be made. In Sweden an electricity meter reading reform was fully implemented by 1st July 2009, including 5.2 million customers, and this created new set of circumstances in the Swedish electricity market. The main purpose of this thesis work has been to investigate the possibilities of increasing the use of remote meter readings. Two research questions have been: “How can the electricity market benefit from remote collected meter readings?” and “Where do barriers appear when utilizing meter readings?”. The work started in 2000/2001 to study Internet based applications that visualize electricity consumption patterns. Over these years the daily internet users have increased from approximately 40 % to 73 % and new markets for web-based applications have evolved. These solutions can be important in the forthcoming years as energy portals that hold new energy services. Experiences from new installations indicate that at least interested customers do submit information concerning building and household properties through internet. Still, it is challenging to enable the majority of customers to take part in these new solutions. It may therefore be important to remind customers on a regular basis in order maintain the frequency using the application and to make it habitual. Further the introduction of demand-based pricing allows electricity distribution utilities to achieve a stronger correlation between peak loads in the distribution network area and their revenues.

Perceptual rivalry refers to visual phenomena that are characterised by alternations between different percepts, despite an unchanging sensory input. Two common types of perceptual rivalry are (i) reversible figures — two-dimensional stable images that when viewed, are perceived to switch between different interpretations, and (ii) binocular rivalry — the alternations in image dominance resulting from the presentation of conflicting stimuli, one to each eye. Several investigators have suggested that these rivalling phenomena are mediated by similar neural mechanisms. Such a view, however, has not only been inadequately substantiated, but has also yet to be assessed in the context of a directly testable neurophysiological model. Miller and Pettigrew have proposed a novel, high-level interhemispheric switch (IHS) explanatory model of binocular rivalry. This model conceptualises the perceptual alternations as being mediated by alternations between one hemisphere’s selected image and the other hemisphere’s selected (rival) image. To assess their hypothesis, caloric vestibular stimulation (CVS) was used. CVS is a simple, inexpensive, and non-invasive brain stimulation technique that unilaterally activates high-level attentional areas. In accordance with the IHS model, CVS was found to significantly affect predominance (the duration that one image is perceived relative to the other, within a given viewing period) during conventional binocular rivalry with horizontal/vertical gratings and with orthogonal oblique gratings. The present thesis therefore aims, through the use of CVS, to extend this IHS model of binocular rivalry to reversible-figure alternations and propose a general IHS model of perceptual rivalry. Chapter 1 provides a detailed literature review of the field within the context of comparing both perceptual rivalries. In Chapter 2, investigations are presented on two different reversible figures — the perspective-reversing Necker cube and the figure–ground reversing Rubin’s vase–faces illusion. In these experiments, CVS was found to significantly change observers’ predominance compared to their baseline predominance. These results demonstrate that interhemispheric switching also mediates the alternations of these visual phenomena, in addition to binocular rivalry, thereby extending the IHS model to one of perceptual rivalry in general. Moreover, the findings are interpreted in a cognitive neuroscience context, including a novel proposal of a forebrain framework for the IHS model. Chapter 3 presents CVS experiments that address the issue of percept–to–hemisphere selection and the reproducibility of CVS effects, following Miller’s initial work on two types of conventional binocular rivalry. In planned analyses, significant predominance changes were not found in horizontal/vertical rivalry, oblique rivalry and Necker-cube rivalry. In post-hoc analyses that accounted for study-design differences between Miller’s original experiments and the present experiment, CVS was again not shown to induce significant predominance changes in any of the rivalry types. Assessment of directional predominance changes following CVS appeared to suggest an arbitrary selection of percept–to–hemisphere in all rivalry types, although no firm conclusions could be drawn from the obtained data on this issue. Nevertheless, the experiments further extend upon Miller’s earlier work by examining the inter- and intra-individual reproducibility of CVS-induced effects on predominance. Such reproducibility was found to be low and potential reasons for this are discussed. The experiments in Chapter 4 examine a type of binocular rivalry in which dichoptic presentation of Díaz-Caneja stimuli yields rivalry among four different stable images: half-field rivalry between the images presented to the eyes, and coherence rivalry in which aspects of each eye’s presented image are perceptually regrouped into rivalling coherent images. Each of these rivalries was found to occur for about half the given viewing time. Furthermore, CVS significantly shifted the predominance of perceived coherent images (coherence rivalry) but not half-field images (eye rivalry). This finding suggests that coherence rivalry (like conventional rivalry according to previous experiments) is mediated by interhemispheric switching at a high level, while eye rivalry is mediated by intrahemispheric mechanisms, most likely at a low level. In addition, it is proposed that Díaz-Caneja stimuli induce ‘meta-rivalry’ whereby these discrete high- and low-level competitive processes themselves rival for visual consciousness. The current thesis thus presents a novel meta-rivalry model of multistable binocular rivalry. It also presents the first direct evidence that interhemispheric switching mediates reversible-figure alternations, thereby supporting a generalised IHS model of perceptual rivalry. It is argued that both models provide a parsimonious exploratory framework within which specific predictions can be made and readily tested. Finally, the findings of all experiments in the current thesis are summarised.

Increasing involvement with students at the University of Namibia has indicated their overall difficulty with comprehending and recalling information from oral content lectures. It has also been observed that in general very little attention is given to the development of listening skills in L2 ESP and EAP courses. For this study, I conducted a quasi-experiment to determine whether the recognition and interpretation of discourse markers will enhance students' listening comprehension in academic lectures. Students were tested to determine their comprehension of content information in a video-taped lecture. Qualitative data were collected by means of a questionnaire. After an intervention period of eight weeks, where the experimental group received strategy training in the recognition and interpretation of discourse markers in spoken texts, both groups were again tested. Their results were statistically compared. I also looked at related findings of other researchers. Finally, aspects for possible future research will also be considered. / English Studies / MA - (Specialisation in TESOL)

Foram levantados os principais modelos teóricos de implementação de políticas públicas, o contexto do tema no Brasil e o resultado prático em outros países que já adotaram uma base curricular comum. Buscou-se, em remate, propor soluções para viabilizar o processo de implementação da BNCC. / The present work was carried out with the purpose of answering the question “how to make the ‘Base Nacional Comum Curricular (BNCC)’ reach the classrooms?”, considering the main challenges related to the implementation process of the Base’s document, due, in large part, the fact that Brazil is a country with very different socioeconomic realities and mores, and the national basic education system consists of an extensive network, spread over a vast and diverse territory. Were analyzed the main theoretical models for the implementation of public policies, the context of the theme in Brazil and the practical result in other countries that have already adopted a common curricular basis. It was sought, in closing, to propose solutions to make viable the process of implementation of the BNCC.

This thesis investigates policy formulation and implementation processes in Zambia. A number of issues emerge with respect to the weaknesses of the system and how policy decisions worsened Zambia's economic performance instead of improving it. The Kaunda era policies of nationalization had an adverse impact on productivity of industries as well as affecting the resource flow from donors and business houses. On the other hand President Chiluba's reforms in the 1990s have had both positive and negative impacts on the people of Zambia. The rapid privatization and liberalization affected employment levels thereby worsening the poverty levels. Further, the liberalization brought in stiff competition from other countries forcing most manufacturing companies to close down. The policy environment based on the Bretton Woods Institutions seems not to be working as result of not taking into account the local Zambian situation. On the other hand, there were positive macroeconomic developments such as growth in GDP, lowering of inflation and stabilizing of exchange rates as from 1996. This has however not improved the living standards of the people. In Zambia, the shifts back and forth between strong and weak planning institutions have negatively affected policy development and implementation. There has been uncoordinated policy development; as a result, some policies in the major sectors are contradictory while in other cases policies are not linked to the resource envelope, making them un-implementable. Secondly, the institutional framework for policy development is not effective. There is generally lack of coordination among ministries, provinces and other stakeholders in planning, implementation and monitoring and evaluation of development programmes. This thesis urges that the improving planning capacities at the national, provincial and district levels should improve the processes of policy development and implementation in Zambia, which will in turn help to reduce poverty. Further, the districts should be the centre for the bottom-up process. In order to carryout this responsibility, efforts should be made to improve their capacities. As for the top-down process, the Sector Advisory Groups should continue to participate in the planning, monitoring and evaluation so as to contribute to policy formulation and implementation. These should be coordinated by the National Development Coordinating Committee (NDCC) through a Planning Bureau. / Development Studies / D. Litt. et Phil. (Development Studies)

The complexity of credit-money is conceived as the central issue in the banking-macro nexus, which the author considers as a structural as well as process component of the evolving economy. This nexus is significant for the stability as well as the fragility of the economic system, because it connects the monetary with the real domain of economic production and consumption. The evolution of credit rules shapes economic networks between households, firms, banks, governments and central banks in space and time. The properties and characteristics of this evolutionary process are discussed in three sections. First, the author looks into the origins of the theory of money and its role for contemporary monetary economics. Second, he briefly discusses current theoretical foundations of top-down as well as bottom-up approaches to the banking-macro nexus, such as dynamic stochastic general equilibrium and agent-based models. In the third part he suggests an evolutionary framework, building on a generic rule-based approach, to arrive at standards for bottom-up foundations in agent-based macroeconomic models with a banking sector.

In this paper, top-down and bottom-up processing were studied regarding their effect on speech-in-noise. Three cognitive functions were also studied (divided attention, executive functioning, and semantic comprehension), and the effect they have on the speech processing and on each other. The research questions asked were if a difference in speech-in noise perception can be observed regarding the different levels of top-down and bottom-up support, if speech-in-noise is related to any of the researched cognitive abilities, and if there exists any correlation between these abilities. The method is a within-subject experimental design, consisting of four different tests: PASAT, to measure attention, LIT, to measure semantic comprehension, TMT, to measure executive functioning and SIN, to measure speech-in noise. The results showed a significant difference between top-down and bottom-up processing, a significant difference between top-down processing in decreasing and increasing conditions could also be seen. A negative correlation between the benefit of top-down support and the semantic comprehension task was found. Regarding the cognitive abilities a few correlations were found; the semantic comprehension task had a positive correlation to both the central executive task and the attentional task, the attentional task had a negative correlation to the central executive task, and both of the central executive subtasks had a positive correlation to each other. Most of the findings were expected, built on earlier cognitive hearing theories and studies.

Abstract Bachelor thesis in political science by Alexander Hassan, autumn 2008, “Effects of external factors on a nations democratisation process during the transition from authoritarian to electoral democratic rule – A categorical analysis” Supervisor: Tomas Sedelius In recent years globalization has become a hot topic in understanding the world we live in today. Globalization has indeed had a great impact on international relations and with it a great influence on the domestic conditions that determine a nation’s possibilities. It is therefore rational to hold true that this also would apply to a nation’s democratic process. This basic notion is what lies as a foundation for the thesis, where the purpose of the study is to examine the relatively new field of the international context and its significance on democratisation. The aim of the study is to examine and determine, through a categorical analysis, the different forms and roles that the external factors can take during the process leading up to the transition and implementation of an electoral democracy, the most basic form of democracy. The thesis thus has demanded the study and infusion of all discourses within the field of democratisation processes, as the only way to produce the roles and forms of the international contexts impact on the domestic process is through the study and determination of the different domestic spheres associated with the process. The different forms of external influences have been studied within the confines of the third wave of democracy, and their roles in the democratic process determined depending on the respective domestic spheres they affect. The significant result of the studies where chiefly that all forms of external influence have the possibility to affect the democratisation process indirectly as well as directly. Where direct influence is exerted within the political sphere of the nation; where the actual transition takes place, and the indirect influence is exerted through the socio-economical and cultural sphere; which exerts its influence in the process through the political sphere.  The results thus show that it is hard to draw the conclusion that an indirect form of influence would be superior to the direct approach or vice versa, as both are prevalent in successful democratic transitions.
