Text in English / Health Communication Campaigns are one of the strategies used in facing the challenges of the spread and effects of the HIV/AIDS epidemic, which is not only a health issue but also has sociocultural implications and consequences. Although there are some models and research tools available to guide the planning, designing, implementing, monitoring and evaluation of health communication campaigns, the premise of the study was on two assumptions. First, most available models that guide the planning and execution of HIV/AIDS communication campaigns do not sufficiently highlight sociocultural variables; and second, since most available models do not sufficiently emphasise sociocultural variables, the design of the instruments for the assessment of the campaigns are not sufficiently geared towards identifying and assessing sociocultural variables of the campaigns. In light of these assumptions, the study was undertaken for three reasons. Firstly, to construct a sociocultural health communication campaign conceptual model that incorporates and highlights sociocultural variables to guide the planning and implementation of health communication campaigns; particularly HIV/AIDS communication campaigns. Secondly to develop an assessment instrument for assessing the presence or absence of sociocultural variables in the planning and implementation of health communication campaigns. Thirdly to test the theoretical sociocultural assessment instrument developed in the study in an HIV/AIDS communication campaign of the Ekurhuleni Metropolitan Municipality’s HIV/AIDS Unit. The results indicated that the instrument is a functional sociocultural assessment tool that can be used to determine three main aspects. Firstly, whether or not and at what level there is/or was active involvement and participation of the target audience in the communication campaigns process. Secondly, whether or not and at what level in the planning and execution of a campaign, the sociocultural context was taken into consideration and the relevant elements of such context incorporated in the campaign process. Thirdly, whether or not and at what level relevant theories/models underpinned the whole process of the health communication campaigns in the planning, designing, implementation, monitoring and evaluation stages. The sociocultural assessment instrument, therefore, is not meant for assessing the effectiveness of health communication campaigns per se. It is rather meant for use to ascertain the presence or absence of those three aspects on the assumption that if they are taking care of in the planning and implementation of such campaigns, the probability is that the campaigns would be more socioculturally appropriate. The implications of this study are that for health communication campaigns to be socioculturally appropriate, they display continuous community interactivity and participative (ensuring mutual relationship between campaign planners and target audience) in their planning, implementation and evaluation/assessment; making the whole campaign process strategic and integrative – their management should be strategic, implementation creative and monitoring and evaluation continuous. / Communication Science / D.

In the present work a simulation model for examining the fundamental dynamic behaviour of a servo driven powertrain is developed. This powertrain consists of a permanent magnet synchronous motor, a cycloidal gearbox and a torque motor to apply a load. On basis of this model the selection of components for the design of a test rig is possible. This leads to the constructive draft of the test rig. In order to model the system, the fundamentals give a brief overview of the components incorporated in the test rig system. With ais of the specified task the simulation purpose is defined and the modelling process enabled. The subsequent system analysis is performed intensively to decompose the system into subsystems, which are then investigated to find the optimal modelling approach for the given simulation task. Particular emphasis is put on the investigation of the cycloidal gearbox subsystem and it shows, that approaches for modelling the dynamic behaviour of the gearbox as a whole have only been published partially. Therefore, the available modelling approaches are analysed and suitable models are developed as conceptual models. Those will be formalised and implemented in Matlab/Simulink. The model is verified and simulation experiments are performed, that help in the selection of suitable test rig components. On basis of a flexible test rig, finally the constructive draft is presented.

Text in English / Born at a time of abundance of technology, including new media, e-teens have their lives woven around the use of new media technologies to the extent that they virtually do everything with the aid of these technologies, including learning, playing, socialising and communicating. E-teens, besides, demonstrate marked expertise in the use of these technologies. Although there have been various studies done on this group of users supported by models and theories on the use, gratifications and appropriation of new media technologies, the premise of this study was on two assumptions. First, there are limited studies that have been conducted in the sub-Saharan African context, especially, Ghana. Second, most available theories and models that guide the study of e-teens’ use, appropriation and the use of new media technologies are generalized and do not sufficiently highlight the unique attributes and gratification needs that are tied to their developmental stage. In light of these assumptions, the study was undertaken to provide empirical evidence on the types of new media e-teens have access to; the types of new media used by e-teens in their scheme of things and e-teens’ purposes for using new media. It also sought to find out the gratifications sought and obtained from the use of new media technologies by e-teens; the key features of new media appropriation and experience among e-teens and to identify the features of new media technologies which are most appealing to e-teens. The other objective, which serves as the main contribution of this study, was to develop a conceptual model representing new media use and appropriation among e-teens, thereby filling the theoretical or conceptual gap that exists in this context. The study adopted a quantitative approach whereby data was collected using close-5ended questionnaires. The target population were teens from age 13 to 19 in senior high schools in the Greater Accra region of Ghana, selected using a simple random sampling. The results of the study show that, overall, the most popular new media technology that e-teens had access to and owned was the smartphone. Leading among the apps that e-teens found to be appealing were educational, entertainment and information/news, with communicative and participatory features of new media technologies appealing to e-teens highly. Also, educational, sociability and social inclusion, respectively, were the most popular gratifications sought and obtained by e-teens. It is submitted that social inclusion, educational and sociability gratifications are considered to be directly in line with the unique developmental needs of e-teens. However, it is recommended, among other things, that educational use of new media, which was one of the strong points for new media use, should be further encouraged as new media provides borderless opportunities for learning. The researcher believes that the conceptual model for e-teen use and appropriation of new media technologies provide a firm ground for further research on topics related to this subject matter. To provide support and substance to the e-teen model, other researchers are encouraged to test and extend it where necessary. In conclusion, the findings provide evidence that new media technologies are highly appropriated by e-teens because the technologies help them meet their unique gratification needs. Therefore, the study recommends that, although new media use among e-teens can be encouraged, it is important to ensure proper usage, which will not be detrimental to them. / Communication Science / D.

PhDRDV / Institute for Rural Development / Providing access to knowledge and connecting it to the needs of individuals as well as grassroots community have always been at the centre of the mission and purpose of public libraries. Numerous studies conducted in various parts of the world have shown that public libraries are the anchor of the lives of communities where they are established. These studies have revealed that information needs may not be the same for different age groups and for different genders. For that reason many countries have been investing in the establishment of community libraries. In South Africa, a community libraries conditional grant was introduced in 2007 to build capacity for public libraries through building additional libraries and renovating existing ones so that they provide information that will satisfy information needs of all community members. However, there are still concerns about the functionality of public libraries and need to strengthening their capacity so that they adequately address community information. This study was conducted on rural community libraries in Mutale located in the Vhembe District of Limpopo Province, South Africa. The main objective was to develop a model for enhanced functionality of public libraries for rural community development. The study was conceptualized around the ecological framework (Asselin and Doiron, 2014). The specific objectives were: to identify challenges faced by the library in providing services to adults, youth and children: to establish if information needs of adults, youth and children varied due to age, and to assess the level of satisfaction of adults, youth and children with the services of the local public library. The study used an exploratory sequential mixed method design with the qualitative phase preceding the quantitative phase. The qualitative phase had two phases. In the first, phase fourteen key informants were purposefully selected and engaged in face-to-face interviews as well as one focus group. Qualitative data from this phase were analysed using atlas.ti version 8. Results distilled showed that the library was hampered by centralized library services which were run from the district level, insufficient funding, inadequate library operating hours and lack of ICT support. In the second phase, a total of 150 adults, youth and children were purposefully selected and engaged in face-to-face interviews as well as focus group discussions. An interview guide complimented by camera, and voice recorder were used to collect data from the respondents. Atlas ti version 8 was used to analyse the data. The results showed that information needs of the community were not fully met by provisions in the library. A variety of information resources expected to satisfy the needs of adults, youth and children respectively include increased number of computers with internet connection, extended library opening hours including Saturdays , stakeholder engagement to be recognized, the extensive marketing of the library for it to be used by the community and the need to improve the amenities and library infrastructure. Results obtained in the qualitative phase of the study informed the second quantitative phase . During this phase, an evaluative survey was conducted with adults, youth and children. Convenience and snowballing techniques were used to sample 176 respondents. A questionnaire with a Likert-type ranking scale was used to collect data. The International Business Machines, Statistical Product and Service Solutions (IBM SPSS) version 24 was used to analyse the data. Chi Square and Crammer’s V tests were performed on the data. It was established that more female (59%) than male (41%) respondents used the library. Of the respondents engaged 26% o were children; 30% were youth and 55% were adults. In terms of travelling to access the library services 32% of the respondents travels less than two kilometers while 68% travel more than two kilometers. This indicates that the majority of the users have a challenge of accessing the library due to distance. The majority of the respondents (70%) did not use the library frequently, with only 30% being active library users. Significant differences in accessing library services were observed according to age in terms of “Current books on all subjects”, “Major reference works such as Encyclopaedias and dictionaries”, “Books on arts and crafts”, “Audio-visual materials” and “Electronic databases”. No significant differences according to gender were observed on all aspects on availability of materials except for “Children’s materials”. Only the perception on availability of “Current books on all subjects” showed a moderate relationship across age (based on the Cramer’s V value >.3). However, on all the aspects where the results showed an association by age and gender the relationship was deemed weak as demonstrated by Cramer’ V values (<.3). Generally, all the respondents (adults, youth and children) were not satisfied with the ICTs, availability of information and available services and amenities. Chi-square tests showed no significant associations between age and perceptions on ICT resources of an ideal library, available services, available amenities, marketing of library services, availability of materials in the library and type of information needed to make informed decisions. These results imply that for the library to provide unhindered services, there must be an enabling environment for the smooth running of the library. There is a need for government to review the policy of running the libraries from districts, as this negatively impacts on opening hours, acquisitions of materials and ICTs support. The library needs to do a periodic survey of the information needs of the community so that it responds by providing relevant and current resources. The study proposed a conceptual model that will enhance the functionality of libraries and to enhance their capacity to offer better services to their users. The proposed model is anchored on nine broad areas which are strengthening human resources, funding, access and accessibility, partnerships, infrastructure, ICTs, management, stakeholder consultation and periodic users’ surveys. Thus, if these interventions are heeded to, there is a higher possibility that the library will be more functional and better positioned to close the information gap. The study contributes to the body of knowledge through provision of a conceptual model which highlights factors that hamper smooth provision of library services, and offers pillars (components of the model) that can enhance the functionality of public libraries in rural areas. It further contributes by highlighting those services regard by users to be important for maximal usage of libraries. This study was unique in that as at the time of completion according to the investigator’s knowledge no other study on rural public libraries has looked into the functionality of libraries funded by the conditional grant using a variety of methods, different perspectives through engaging key informants, factoring in the different age groups and bringing in the gender perspective in a single study. Use of different computer assisted software packages (Atlas version 8 and SPSS version 24) over and above the thematic content analysis to analyse the data was also unique as most other known studies only used thematic content analysis for their qualitative data. Based on the findings it was concluded that decentralized services to local municipal level could reduce many of the challenges that hinder libraries from providing smooth and quality services to their communities. Improved materials collections to satisfy individual and communal information needs, user friendly opening hours as well as engaging the community in library decisions could go a long way in ensuring the library is recognized as a community development hub that fulfills its mission of keeping the community informed. It was therefore recommended that the policy on the running of public libraries should be reviewed with the view to decentralize the running of public libraries to local municipalities,. More still, policy on library funding should be reviewed, library opening hours should be extended, better trained ICT technicians should be placed in local libraries, librarians should be appointed on a permanent basis, and a comparative study of all libraries in Vhembe should be conducted to gauge if the community is deriving any benefits from the provision of computers and access to the internet through “Mzansi Online” project. / Staff Capacity Development

L’objectif de cette thèse est de caractériser les Rejets Urbains par Temps de Pluie (RUTP) et leur flux au niveau des exutoires d’eaux pluviales de trois sous-bassins majeurs de l'agglomération orléanaise. Pour cela des prélèvements ponctuels d’eau ont été effectués et un modèle conceptuel a été utilisé. Les trois sous-bassins : La Corne (463 ha), l'Egoutier (2080 ha) et Ormes (2256 ha) ont des occupations du sol différentes.D’une manière générale, la conductivité, la demande chimique en oxygène (DCO), la demande biochimique en oxygène (DBO5 et la DBO28), le carbone organique dissout (COD), l'azote total(NT), et les concentrations en anions et cations majeurs étaient plus élevés par temps sec que par temps de pluie indiquant un effet de dilution par les précipitations. Il a été mis en évidence un mélange des eaux pluviales avec des eaux usées dans le sous bassin d’Ormes. L’occupation des sols et les activités anthropiques influencent de manière significative la qualité du ruissellement. Par exemple, dans le sous-bassin de l’Egoutier, la présence d’une zone imperméable (industries et habitations) importante (40% de la surface) est responsable d’une augmentation des paramètresDBO5, DBO28, COD et NT.Les flux aux exutoires des différents paramètres de qualité de l’eau ont été évalués et comparés à ceux issus des quatre principales stations d’épuration (STEP) et à ceux de la Loire. La charge destrois sous-bassins urbains représente environ 166,61% de la charge des quatre STEP. Les trois sous bassins ont un faible impact sur la Loire en termes de flux annuels (environ 1,62% pour les MES par temps de pluie).Deux versions d’un modèle conceptuel dit d'accumulation/lavage-transport ont été évaluées pour estimer les flux de ruissellement des polluants ; la version classique et une version modifiée dans laquelle le paramètre accumulation des polluants a une forme logarithmique. Les performances des modèles étaient acceptables pour les MES et la DCO. Les coefficients de corrélation étaient supérieurs à 90% pour le sous bassin de l’Egoutier, par exemple. Pour les éléments traces métalliques en phase particulaire, la corrélation avec l’expérience était bonne également. D’une manière générale, lorsqu'un flux mesuré était inférieur à 1 kg.ha-1, les modèles n’étaient plus applicables.Des premiers essais de simulation de la qualité et la quantité de RUTP ont été effectués à partir de MIKE URBAN, qui équipe les deux logiciels de modélisation MOUSE et SWMM. Les hydrogrammes ont indiqué que le débit maximum obtenu avec SWMM était toujours inférieur à celui obtenu avec MOUSE. La qualité de l’eau (masse de MES) était toujours plus fortement impactée par le lessivage des MES dans le modèle MOUSE que dans SWMM.Ce travail constitue la première étape du travail d'évaluation de RUTP pour l'Agglomération orléanaise. Il constitue une base solide pour un futur programme de surveillance continue. / The objective of this thesis was to characterize urban runoff water at the level of stormwater outletson three major urban sub-basins of the Orléans agglomeration, covering land areas ranging in size from463 to 2257 ha and with contrasted land use. 11 individual rain events were sampled at runoff outletsbetween April 2015 and June 2017 and 10 campaigns were also carried out in dry weather.In general, it was observed that the conductivity, chemical oxygen demand (COD), biochemicaloxygen demand (BOD5 and BOD28), dissolved organic carbon (DOC), total nitrogen (NT), anions andmajor cations were found to be higher in dry weather conditions than in rainy weather. These resultsindicate a dilution effect due to precipitation.A mixture of rainwater and wastewater was also identified in the sub-basin of Ormes. Land use andhuman activities in the sub-basin studied were found to significantly influence the quality of the resultedrunoff from rainfall events. For example, in the Egouttier sub-basin 2, the presence of a large imperviouszone (industrial and residential, 40% of the surface area) was responsible for an increase in the parametersBOD5, BOD28, COD and NT.The flows at the outlets of the different water quality parameters were evaluated and compared withthose from the four main wastewater treatment plants (WWTP) and those from the Loire. The estimatedloads of the three sub-urban basins accounts for approximately 166.61% of the load of the four WWTP.The three sub-basins have a small impact on the Loire in terms of annual flows (about 1.62% for wetweather case).Two versions of a conceptual model of accumulation / washoff were evaluated to estimate pollutantrunoff; the classical version and a modified version in which the pollutant accumulation parameter has alogarithmic form. The performances of the models were found acceptable for the MES and the COD. TheNash-Sutcliffe (NS) coefficients were found as 0.84 and 0.85 for the two versions at the Egouttier subbasin.For trace elements in particulate phase, the correlation with the experimental measured value wasfound good as well. In general, when a measured flow was less than 1 kg.ha-1, the modified model was nolonger applicable.The first simulation tests of the quality and quantity of urban runoff were carried out with MIKEURBAN, which equips both MOUSE and SWMM modeling software. For water quantity, the hydrographsindicated that the maximum flow obtained with SWMM was always lower than that obtained with MOUSE.For water quality, TSS mass was still more strongly impacted by the leaching of TSS in the MOUSE modelthan in the SWMM model.This work can be considered as the first step of the evaluation work of RUTP for the Orléansagglomeration. It provides a solid foundation for a future monitoring program.

[EN] Renewing software systems is one of the most cost-effective ways to protect software investment, which saves time, money and ensures uninterrupted access to technical support and product upgrades. There are several motivations to promote investment and scientific effort for specifying systems by means of conceptual models and supporting its evolution. In order to contribute to the requirements engineering field with automated software production methods, we design TraceME to cover the spectrum of activities from requirements to code focusing on organisational evolution. In this sense, the spectrum of activities involves various information system perspectives of analysis that need to be integrated. In this complex setting, traceability and conceptual models are key concepts. Mechanisms to trace software specifications from requirements to code are important to justify evolution processes; versions of information systems should be traced in order to get the connection between old and new specifications. Moreover, it is necessary to find mechanisms to facilitate change specifications, measurement, and interpretation. To design this thesis we follow Design Science by Roel Wieringa. Design Science gives us the hints on how to conduct the research, be rigorous, and put in practice scientific rules. Besides Design Science has been a key factor for structuring our research, we acknowledge the application of this framework since it has helps us to report clearly our findings. We build TraceME by making a method engineering effort, which shapes its fragmented nature in chunks. The architecture of TraceME opens a wide window of opportunities for its application in real world situations. To facilitate industrial adoption, we develop open source tools to support the implementation of the TraceME chunks. For example, one case study and one action-research protocols have been executed in two different organisations in Spain. The validation of TraceME has taken place in laboratory demonstrations, controlled experiments, action research and case study experiences in industry. Thanks to the validations various lessons learnt have been gathered and greatly influenced the maturity of the method. For example: the importance to consider end-users' perceptions for discovering needs to mitigate, and the significance to get knowledge from the application of TraceME in different contexts. The evidences from the validations demonstrate that TraceME is feasible to be applied to support evolution projects. In addition, future research is needed for promoting the implementation of TraceME. We envision short term and future-term work that motivate us to tackle the challenge to support evolution projects. / [ES] La evolución de sistemas software es una de las actividades mas importantes que permiten minimizar el tiempo de puesta en producción de actualizaciones y nuevos desarrollos, reducir los costos que implica desarrollar una aplicación desde cero, y además asegura el acceso ininterrumpido de servicios. Existen variadas motivaciones para promover la investigación y desarrollo de soluciones para especificar y evolucionar sistemas de información mediante modelos conceptuales. Para contribuir al campo de la ingeniería de requisitos con métodos automáticos de producción de software, hemos diseñado el método TraceME para cubrir el espectro de actividades desde requisitos a código con un enfoque de evolución organizacional. De este modo, el espectro de actividades involucra diferentes perspectivas de análisis de sistemas de información que necesitan ser integradas. En este escenario tan complejo, la trazabilidad y los modelos conceptuales son conceptos clave. Es necesario disponer de mecanismos para trazar especificaciones de software desde requisitos a código con el fin de justificar procesos de evolución. Las versiones de los sistemas de información deben ser trazables con el fin de establecer la conexión entre especificaciones obsoletas y actuales. Adicionalmente, es necesario encontrar mecanismos para facilitar la especificación del cambio, su medición e interpretación. Para diseñar esta tesis hemos seguido el marco de Design Science de Roel Wieringa. Design Science nos ha proporcionado las claves para conducir esta investigación, ser rigurosos y poner en práctica reglas científicas.

La arquitectura de TraceME abre una amplia ventana de oportunidades para su aplicación en situaciones de la vida real. Para facilitar la adopción industrial de TraceME, hemos desarrollado herramientas de software libre para dar soporte a los fragmentos de TraceME. Por ejemplo, un caso de estudio y una experiencia de action research han sido ejecutadas en dos organizaciones en España. La validación de TraceME ha sido llevada a cabo mediante demostraciones de laboratorio, experimentos controlados, un caso de estudio y una experiencia de action research en industria. Como resultado, TraceME ha sido mejorado considerablemente; además hemos descubierto investigaciones a realizar a corto, mediano y largo plazo con el fin de implementar TraceME en la industria. Las evidencias obtenidas como resultado de las validaciones demuestra la factibilidad de TraceME para ser aplicado en proyectos de evolución organizacional. El trabajo futuro nos motiva a afrontar los retos que conlleva el soporte de proyectos de evolución de sistemas de información. / [CA] L'evolució dels sistemes programari és una de les activitats més importants que permeten minimitzar el temps de posada en producció d'actualitzacions i nous desenvolupaments, reduir els costos que involucra desenvolupar una aplicació des de cero, a més d' assegurar l'accés ininterromput de serveis.

L'arquitectura de TraceME obri una ampla finestra d'oportunitats per a la seua aplicació en situacions de la vida real. Per facilitar l'adopció industrial de TraceME, hem desenvolupat ferramentes de programari lliure per tal de donar suport als fragments de TraceME.

Les evidències obtingudes com a resultat de les validacions, demostren la factibilitat de TraceME per ser aplicat en projectes d'evolució organitzacional.
