Thesis (MA)--Stellenbosch University, 2004.<br>ENGLISH ABSTRACT: Treatment outcome research strives towards objective estimates of disorder-specific treatment efficacy and has been applied to most psychiatric disorders. However, due to shortcomings in outcome research designs, problems still remain regarding the interpretation and generalisability of treatment outcomes. This is despite the development of research methodology criteria such as the Gold Standards, currently viewed as essential criteria for well-controlled cognitive-behavioural outcome research. The objectives of this assignment are (a) to assess the Gold Standards as criteria for treatment outcome research by means of a qualitative overview and evaluation of exposure treatment studies for PTSD, and (b) to make recommendations for the expansion and/or modification of these criteria. An assessment of five selected treatment outcome trials, based on the Gold Standards, showed significant limitations in the scope of the Gold Standards regarding (a) the inclusion of target symptoms in the research hypotheses, (b) estimates of treatment adherence, (c) guidelines for statistical analyses of attrition points, (d) the ethical implementation of exposure treatment, and (e) estimates of significant clinical change. It is concluded that the Gold Standards are not sufficient to ensure valid and reliable treatment outcomes. Recommendations are made for the expansion of four of the existing Gold Standards parameters and three additional criteria are proposed. Key words: treatment outcome research, Gold Standards, post-traumatic stress disorder, exposure therapy.<br>AFRIKAANSE OPSOMMING: Navorsing oor behandelingsuitkoms streef na objektiewe resultate oor die uitkoms van behandeling vir spesifieke psigiatriese versteurings. Nogtans, weens tekortkominge in die ontwerp van uitkomsstudies, word talle probleme steeds ervaar met die interpretasie en veralgemeenbaarheid van die resultate van die studies. Dit is die geval ten spyte van die ontwikkeling van navorsingskriteria soos die "Gold Standards" wat huidig as die belangrikste kriteria vir uitkomsstudies op die gebied van die kognitiewe gedragsterapie aanvaar word. Hierdie projek het ten doelom (a) die Gold Standards as kriteria vir uitkomsnavorsing te assesseer deur middel van 'n kwalitatiewe oorsig en evaluering van vyf geselekteerde uitkomsstudies van blootstellingsterapie vir post-traumatiese stresversteuring, en (b) om aanbevelings te maak ter aanvulling enJofwysiging van die Gold Standards. Evaluasie van die studies het betekenisvolle beperkings in die Gold Standards se omvattenheid uitgelig in terme van (a) die insluiting van teikensimptome in die navorsingshipoteses, (b) die skatting van behandelingvoitrekking ("treatment adherence"), (c) riglyne vir die statistiese analise van data oor attrisie, (d) die etiese implementering van blootstellingsterapie, en (e) skattings van betekenisvolle kliniese verandering. Dit blyk dat die Gold Standards nie voldoende is om geldige en betroubare resultate oor behandelingsuitkomste te verseker nie. Aanbevelings word gemaak vir die hersiening van vier van die Gold Standards kriteria en drie addisionele kriteria word voorgestel. Sleutelwoorde: behandelingsuitkomsnavorsing. Gold Standards, post-traumatiese stresversteuring, blootstellingsterapie.

How do teachers develop an understanding and make interpretations of the assessment criteria used for standards-referenced assessment like School-Based Assessment (SBA) in Hong Kong? The thesis attempts to offer an answer to this question through researching four English Language teachers teaching in a secondary school over a period of two years (2008 -2010). Understanding the meanings of the criteria used for the standards-referenced assessment is the primary focus of this study. Keeping track of the teachers’ opinions on the content and the use of criteria, this case study draws upon qualitative data from the interviews with the teachers after each assessment, and from regular meetings on standardizing scores, setting tasks and training on standards in the two-year assessment cycle. Focus group interviews with their students were used to triangulate the data collected from their respective teachers. The main findings from this study are as follows: the teachers demonstrate variability in their level of understanding and interpretations of the criteria, through which they use to rate students’ oral performances in SBA context. This understanding of the meanings of the criteria enhanced when they start using it. Teachers also adopt the criteria in other contexts such as meetings to standardize scores, to set assessment tasks and to familiarize themselves with the standards .Regarding their self-perceived role as assessors, the four teachers embrace a range of roles such as a follower, a team player, a game player, and a believer. This study is significant as it informs how teachers involved in understanding the meanings of standards-referenced criteria. This conceptualization process would be enhanced if teachers are given opportunity to share their views towards the assessment criteria and their roles as assessors in a professional community of shared practices.<br>published_or_final_version<br>Education<br>Master<br>Master of Philosophy

Measurement of visual quality is crucial for various image and video processing applications. <br /><br /> The goal of objective image quality assessment is to introduce a computational quality metric that can predict image or video quality. Many methods have been proposed in the past decades. Traditionally, measurements convert the spatial data into some other feature domains, such as the Fourier domain, and detect the similarity, such as mean square distance or Minkowsky distance, between the test data and the reference or perfect data, however only limited success has been achieved. None of the complicated metrics show any great advantage over other existing metrics. <br /><br /> The common idea shared among many proposed objective quality metrics is that human visual error sensitivities vary in different spatial and temporal frequency and directional channels. In this thesis, image quality assessment is approached by proposing a novel framework to compute the lost information in each channel not the similarities as used in previous methods. Based on natural scene statistics and several image models, an information theoretic framework is designed to compute the perceptual information contained in images and evaluate image quality in the form of entropy. <br /><br /> The thesis is organized as follows. Chapter I give a general introduction about previous work in this research area and a brief description of the human visual system. In Chapter II statistical models for natural scenes are reviewed. Chapter III proposes the core ideas about the computation of the perceptual information contained in the images. In Chapter IV, information theoretic criteria for image quality assessment are defined. Chapter V presents the simulation results in detail. In the last chapter, future direction and improvements of this research are discussed.

[EN] The main objectives of this research are the following. First, to analyse the models and methods in Decision Support Systems (DSS) for forest management, taking into account the important features which allow forestry related problems to be categorized. Second, to define strategic criteria for the sustainable management of Mediterranean forests, as well as to elicit and aggregate the stakeholders' preferences. Third, to propose a robust methodology to implement collaborative management focused on ESS and to develop indicators for the main functions of ESS. The methodology is based on a workshop and surveys to elicit the decision makers', experts' and other stakeholders' preferences. Several techniques were then used to aggregate individual judgements and determine social preferences, in particular, Analytic Hierarchy Process (AHP) and Goal Programming (GP). In addition, a PROMETHEE based method has been developed to provide indicators of the ESS, classified into provisioning, maintenance and direct to citizens services. The analysis of DSS for forest management has shown that the best choice of approach to solve a given problem depend on its nature, which can be characterized by the temporal scale, spatial context, spatial scale, number of decision makers or stakeholders, objectives and finally goods and services involved. A decision hierarchy for strategic management of Valencian forests has been developed by involving experts during the design phase. This was later validated in consultation with the stakeholders in a workshop and provides the base from which to obtain the social preferences. The results show greater importance for environmental and social criteria and lesser relevance for economic criteria, valid for both public and private Mediterranean forests. This result is the same regardless of which preference aggregation technique was used and takes into account the preferences of the majority of the stakeholders and also the minority opinions furthest from the consensus. New products and services such as rural tourism, renewable energies, landscape, hydrological regulation and erosion control, biodiversity and climate change mitigation are relevant. This research also proposes a robust methodology to implement collaborative management focused on ESS provided by protected areas and aggregated indicators for their main functions. Decision makers, technical staff and other stakeholders are included in the process from the beginning, by identifying ESS and eliciting preferences using the AHP method. Qualitative and quantitative data are then integrated into a PROMETHEE based method in order to obtain indicators for provisioning, maintenance and direct to citizens services. This methodology, which has been applied in a forest natural park, provides a tool for exploiting available technical and social data in a continuous process, as well as graphical results, which are easy to understand. This approach also overcomes the difficulties found in prioritising management objectives in a multiple criteria context with limited resources and facilitates consensus between all of the people involved. The new indicators define an innovative approach to assessing the ESS from the supply perspective and provide basic information to help establish payment systems for environmental services and compensation for natural disasters.<br>[ES] Los principales objetivos de esta investigación son los siguientes. En primer lugar, analizar los modelos y los métodos de los sistemas de ayuda a la toma de decisiones para gestión forestal, teniendo en cuenta las características relevantes que permiten clasificar los problemas forestales. En segundo lugar, definir los criterios estratégicos para la gestión forestal sostenible del bosque mediterráneo, así como obtener y agregar las preferencias de los decisores y otras partes interesadas. En tercer lugar, proponer una metodología robusta para implementar una gestión colaborativa centrada en los servicios del ecosistema y desarrollar indicadores para las principales funciones de estos servicios. La metodología se fundamenta en una jornada de trabajo con decisores, expertos y otros grupos de personas interesadas, así como en encuestas a todos ellos. Después se han utilizado varias técnicas para agregar las preferencias individuales y determinar las preferencias de los distintos grupos sociales, en particular el proceso analítico jerárquico y la programación por metas. Adicionalmente, se ha desarrollado un método basado en PROMETHEE que permite obtener indicadores de los servicios del ecosistema, clasificados en servicios de producción, mantenimiento y directos a los ciudadanos. El análisis de los sistemas de ayuda a la toma de decisiones para gestión forestal ha puesto de manifiesto que los mejores enfoques para resolver los problemas forestales dependen de su naturaleza, caracterizada por la escala temporal, el contexto espacial, la escala espacial, el número de decisores o personas interesadas, el número de objetivos y por último los bienes y servicios involucrados. Se ha desarrollado una jerarquía de decisión para la gestión estratégica de los bosques valencianos involucrando a expertos en la fase de diseño. Este modelo fue validado posteriormente por las partes interesadas en una jornada organizada con esta finalidad y ha sido la base para obtener las preferencias sociales. Los resultados ponen de manifiesto la mayor importancia de los criterios medioambientales y sociales y la menor relevancia de los económicos, tanto para el monte mediterráneo público como privado. Este resultado es independiente del método de agregación utilizado y tiene en cuenta tanto las preferencias de la mayoría como de la minoría más alejada del consenso. Son relevantes los nuevos productos y servicios tales como el turismo rural, las energías renovables, el paisaje, la regulación hidrológica y el control de la erosión, la biodiversidad y la mitigación del cambio climático. Esta investigación también propone una metodología robusta para implementar una gestión colaborativa centrada en los servicios del ecosistema que proporcionan las áreas protegidas e indicadores agregados para sus principales funciones. Los responsables de las decisiones, el personal técnico y otras personas interesadas han participado desde el inicio del proceso, identificando los servicios del ecosistema y proporcionado sus preferencias mediante la técnica del proceso analítico jerárquico. Después se integran los datos cualitativos y cuantitativos en un método basado en PROMETHEE con la finalidad de obtener indicadores para los servicios de producción, mantenimiento y directos a los ciudadanos. Esta metodología, que se ha aplicado en un parque natural, facilita la explotación de los datos técnicos y sociales en un proceso continuo y proporciona resultados gráficos muy fáciles de entender. Este enfoque también permite superar las dificultades que surgen al priorizar los objetivos de gestión en un contexto multicriterio con recursos limitados y facilita el consenso entre todas las personas involucradas. Los nuevos indicadores representan un enfoque innovador para la valoración de los servicios del ecosistema desde el punto de vista de la oferta y proporcionan información básica para establecer sistemas de pagos por<br>[CAT] Els principals objectius d'aquesta recerca són els següents. En primer lloc, analitzar els models i els mètodes dels sistemes d'ajuda a la presa de decisions per a gestió forestal, tenint en compte les característiques rellevants que permeten classificar els problemes forestals. En segon lloc, definir els criteris estratègics per a la gestió forestal sostenible del bosc mediterrani, com també obtenir i agregar les preferències dels decisors i altres parts interessades. En tercer lloc, proposar una metodologia robusta per a implementar una gestió col·laborativa centrada en els serveis de l'ecosistema i desenvolupar indicadors per a les principals funcions d'aquests serveis. La metodologia es fonamenta en una jornada de treball amb decisors, experts i altres grups de persones interessades, i també en enquestes a tots ells. Després s'han utilitzat diverses tècniques per a afegir-hi les preferències individuals i determinar les preferències dels diferents grups socials, en particular el procés analític jeràrquic i la programació per metes. Addicionalment, s'ha desenvolupat un mètode basat en PROMETHEE que permet obtenir indicadors dels serveis de l'ecosistema, classificats en serveis de producció, manteniment i directes als ciutadans. L'anàlisi dels sistemes d'ajuda a la presa de decisions per a la gestió forestal ha posat de manifest que els millors enfocaments per a resoldre els problemes forestals depenen de la naturalesa d'aquests problemes, caracteritzada per l'escala temporal, el context espacial, l'escala espacial, el nombre de decisors o persones interessades, el nombre d'objectius i, finalment, els béns i serveis involucrats. S'ha desenvolupat una jerarquia de decisió per a la gestió estratègica dels boscos valencians involucrant experts en la fase de disseny. Aquest model ha sigut validat posteriorment per les parts interessades en una jornada organitzada amb aquesta finalitat i ha sigut la base per a obtenir les preferències socials. Els resultats posen de manifest la major importància dels criteris mediambientals i socials i la menor rellevància dels econòmics, tant per a la muntanya mediterrània pública com privada. Aquest resultat és independent del mètode d'agregació utilitzat i té en compte tant les preferències de la majoria com de la minoria més allunyada del consens. Són rellevants els nous productes i serveis, com ara el turisme rural, les energies renovables, el paisatge, la regulació hidrològica i el control de l'erosió, la biodiversitat i la mitigació del canvi climàtic. Aquesta recerca també proposa una metodologia robusta per a implementar una gestió col·laborativa centrada en els serveis de l'ecosistema que proporcionen les àrees protegides i indicadors agregats per a les seues funcions principals. Els responsables de les decisions, el personal tècnic i altres persones interessades hi han participat des de l'inici del procés, identificant els serveis de l'ecosistema i proporcionant les seues preferències mitjançant la tècnica del procés analític jeràrquic. Després s'integren les dades qualitatives i quantitatives en un mètode basat en PROMETHEE amb la finalitat d'obtenir indicadors per als serveis de producció, manteniment i directes als ciutadans. Aquesta metodologia, que s'ha aplicat en un parc natural, facilita l'explotació de les dades tècniques i socials en un procés continu i proporciona resultats gràfics molt fàcils d'entendre. Aquest enfocament també permet superar les dificultats que sorgeixen a l'hora de prioritzar els objectius de gestió en un context multicriteri amb recursos limitats i facilita el consens entre totes les persones involucrades. Els nous indicadors representen un enfocament innovador per a la valoració dels serveis de l'ecosistema des del punt de vista de l'oferta i proporcionen informació bàsica per a establir sistemes de pagaments per serveis ambientals i compensacions per desastres naturals.<br>Segura Maroto, M.

Significant investments are being made in the construction sector in order to raise the quality of the buildings and make them more sustainable and energy-efficient. The key aspect of these investments should be the purposeful optimization of the possible renovation and construction measures. However, this important matter usually is being pushed aside in favor of construction price and/or quality. Nevertheless, there are plenty of criteria that play a major role in building sustainable development. The main purpose of this study is to present a tool that combines multi-criteria decision making (MCDM) methods and building certification systems in order to make weighted decisions in complicated construction tasks. For this, a decision making model was developed with a focus on sustainability, buildings’ life cycle, MCDM methods, and building certification. The first section of this thesis, the introduction, discusses the importance of the investigated area, and the main objectives, tasks, and structure of the thesis. A literature review is presented in Section 2 – Theory. The main works in the area of sustainability, LCA, building certification, and MCDM are collected to show their role and importance and how they interact in the construction industry. Section 3 presents and discusses the main ideas and instructions of the proposed decision making model. Section 4 (Methodology) introduces the main existing and proposed techniques that I have used to implement the study. Sections 5 and 6 are the case studies, which demonstrate how the proposed methods can be used in practice. Final conclusions and recommendations are presented in Section 7.<br><p>QC 20170209</p><br>Funded by L.E. Lundberg foundation

This study explores the issue of generating ordered distributions of Queensland senior secondary school students using criteria-based assessment data. Criteria-based assessment data are multidimensional, yet ordered distributions are unidimensional since order is a property of univariate data. Ordering multivariate data requires the data to be transformed onto a univariate scale and such transformations are called here ordering mechanisms. The ordered distributions obtained from the criteria-based assessment data are used for certification purposes and tertiary entrance selection purposes. Importance is placed on these distributions, yet there seems to be little study of the ordering mechanisms to yield these distributions from multidimensional criteria-based assessment data. This study seeks to address this gap. The purpose of this research is to explore the issue of generating macro-function assessment data from micro-function assessment data. More specifically, this research considers the issue of ordering multivariate educational assessment data for percentage-based assessment systems, and in particular, the nature of the ordering mechanisms for ordering systems within such assessment systems. This study is focused by the following research question: RESEARCH QUESTION: Is there a mathematical system which: - orders all points in a multidimensional percentage-based assessment space, - models preferences within a multidimensional percentage-based assessment space, - can be used to construct an independent ordering system for a percentage-based assessment system? The existence of a mathematical system for modelling ordering mechanisms has been questioned. This study shows that a mathematical system with properties which suggest its applicability for developing ordering mechanisms in assessment systems for certain Board subjects, does exist.

<p>In the recent decades, therehave been frequent conflicts between groundwater waterresources and environmentally hazardous activities. Newmethodologies for aiding decision-making in groundwater impactassessment and protection areneeded and in which issues ofincreased awareness, better understanding of the groundwaterresources processes, and validation of predictive mathematicalmodels are addressed.</p><p>A framework fordecision–aid, based on predictive simulations that a)predicts the environmental impacts b) provides the totaleconomical value c) visualises the impacts and the groundwaterproperties and d) describes the uncertainties in the results isproposed herein.

The results ofthe model are used as feedback for determining new scenarios,depending on the required uncertainties, and if the plannedactivity is sustainable, and/or fulfils the legislative andpolicy measures.

Breakwaters are constructed in coastal areas to protect coastal engineering structures from wave actions. Due to economic reasons, natural stones (armourstone) are very frequently used for the constructions of the breakwaters. Considering the functions of the stones at different zones of the breakwaters, various sizes with variable properties of the armourstones are used in breakwaters.Deterioration of armourstones with time in the form of abrasion and disintegration may end up with the damage of the engineering structures. Therefore, it is necessary to investigate the long-term performance and quality of the armourstones, which should be sound and durable. In this thesis, the properties of four limestones taken from two quarries with a known site performances as armourstones in Mersin and Kumkuyu harbors are studied .The site performances and durability of the limestones are compared with the field measurements and laboratory works. For this purpose, the material and mass properties of the limestones are studied. Thus, the information obtained is used to assess long-term durability of the armourstones. The long&amp<br>#8211<br>term performaces of the Degirmen&ccedil<br>ayi and Tirtar upper level limestones are observed to be good whereas it is rather poor for the Tirtar middle and lower level limestones. Comparison between the predicted and observed durabilities of the armourstones indicated that CIRIA/CUR, RDId, RERS, and wet to dry strength ratio give better results based on their field performances. However, the prediction of the durability of the limestones is poor in case RDIs, average pore diameter, and saturation coefficient are used.

Doctor of Philosophy<br>Department of Human Nutrition<br>Edgar Chambers IV<br>Because healthy food products do not have a specific tool used for consumer screening based on consumers’ diet or degree of healthy eating habits, this study aimed to determine a set of questions that could classify consumers who belong in a different status according to the Stages of Change model, including those who have a different diet quality based on their Healthy Eating Index (HEI) score. The surveys were conducted in the United States (US) and Thailand in order to determine applicability to varying countries. The Food Neophobia Scale (FNS), Food Involvement Scale (FIS), and Health and Taste Attitude Scale (HTAS) were included in the questionnaire together with a set of Stages of Change questions and a 7-day, self-administered food recall questionnaire. The HEI interpretation of US and Thai consumer scores illustrated that the majority of both belonged to the Need Improvement group. The Stages of Change model indicated most consumers thought they had healthy diets. According to FNS, FIS, and HTAS, US consumers are more involved in food activities and are more open to trying new foods or unfamiliar foods than Thais. Furthermore, consumers who belong in different groups, according to the Stages of Change model, responded differently to some HTAS subscales. However, statements from FNS, FIS, and HTAS were not capable of distinguishing consumers belonging in different groups according to HEI scores or belonging in different stages according to the Stages of Change Model. Considering all possible methods from those listed above for screening consumers, the Stages of Change model may be the best way to segment consumers interested in healthier eating. Using the Stages of Change required less time and the least effort from consumers because there were only three questions; and interpreting results does not require calculation or analysis.

Sustainable waste management remains a great challenge for many cities throughout the world. Landfilling is worldwide the most common way of treating municipal solid waste (MSW) and landfilling of organic matter releases the high potent gas methane, which contributes to global warming. If the biogas instead is collected, either from landfills or produced in a more optimal and controlled environment, it can be used as a fuel to substitute fossil fuels. In this thesis, these sorts of systems are referred to as biogas solutions. In Brazil, the eight largest economy in the world and by far the largest economy in Latin America, landfilling of MSW is essentially the only way MSW is disposed of. Rio de Janeiro, the second largest city of Brazil, have had long issues with waste management, with up until 2012 deposing waste to one of the largest open landfills in the world. This study was done in collaboration with Biogas Research Center (BRC): a national biogas competence center with interests in the Brazilian biogas sector as well as contacts with the Federal University of Rio de Janeiro. Furthermore, as Swedish organic waste management practices are globally in the front edge, the Swedish perspective of waste management combined with local knowledge, could be valuable to find more efficient means of managing residues. Before initiating an actual biogas project, it is reasonable to perform an early assessment. This thesis aimed to perform an early assessment of the biogas sector in Rio, which was carried out by utilizing a multi-criteria framework. The framework consists of four categories (potential, feasibility, economic- and environmental performance), 14 key areas and 59 sub-questions, which helped gather, structure and assess information. An eight-week field study in Rio de Janeiro was part of the study. The results show that no full separation of organic content is performed as source in Rio, which is why the study included the waste streams of mixed MSW (disposed in landfills) and partly sorted organic waste (approximately 85 % organic content; referred to as Waste with High Organic Content, WHOC). Sewage sludge from wastewater treatment plants was excluded from the study to enable a focus on MSW. Potential and feasibility are significantly higher for MSW compared to WHOC, although the authors argue WHOC (or even fully sorted organic waste) have substantial growth opportunities. The landfill receives approximately 1.2 million tonnes of organic wet waste per year and provides a biogas yield of 140 million Nm3 / year (50 – 55 % CH4); whereas 26 – 42 thousand tonnes of dry matter (DM) per year can be collected from WHOC, with a biogas yield potential of 6.6 – 19.5 million Nm3 / year (55 – 63 % CH4). The feasibility analysis showed that all key areas – competing applications, legislation and infrastructure – except economic instruments, are better rated for biogas production from MSW compared to WHOC. The most feasible area of use for the biogas in Rio de Janeiro was deemed to inject the gas in into the grid. The indicated environmental performance shows that injection of biogas to the gas grid reduces GHG emissions with 68 %; and for every tonne of DM digestate, approximately 8 kg phosphorous and 36 kg nitrogen can be replaced. The economic performance shows that biogas production from the landfill is more cost-efficient than from a bioreactor, however none of the biogas productions in Rio de Janeiro is profitable, which usually is expected of a waste management system. The study concludes with identifying several challenges the biogas sector in Rio will be facing: a lack of supply of biogas and no plan in action for increasing demand; economic challenges indicating need for investment support; and a lack of value chain for biofertilizers. The results of the study can hopefully provide stakeholders with a better understanding of opportunities and challenges with biogas solutions in Rio de Janeiro municipality, that ultimately can increase the chance for successful implementation in the region.<br>Hållbar avfallshantering är fortsatt en stor utmaning för många städer runtom i världen. Deponering är globalt sett det vanligaste sättet att göra sig av med fast kommunalt avfall och deponering av organiskt avfall avger den potenta gasen metan, som bidrar till global uppvärmning. Om biogasen istället samlas upp, antingen från deponin eller produceras i en mer optimal miljö, kan gasen istället användas som bränsle för att substituera fossila bränslen. I denna rapport kallas denna typen av system för biogaslösningar. I Brasilien, världens åttonde största ekonomin och den avsevärt största ekonomin i Latinamerika, hanteras fast kommunalt avfall i princip endast genom deponering. Rio de Janeiro, Brasiliens nästa största stad, har länge haft problem med avfallshantering, som fram tills 2012 slängde allt sitt avfall i en av världens största öppna deponier. Denna studie genomfördes i samarbete med Biogas Research Center (BRC): ett nationellt kompetenscenter inom biogas med intresse av den Brasilianska biogassektorn, samt med kontakter till det federala universitetet i Rio. Eftersom Sverige ur ett globalt perspektiv ligger i framkant vad gäller hantering av organiskt avfall, kan den svenska synvinkeln av avfallshantering kombinerat med lokal kunskap vara värdefull för att hitta effektivare avfallshanteringssystem. Innan man genomför ett skarp biogasprojekt är det klokt att göra en förstudie. Denna uppsats syftar till att genomföra en förstudie av biogassektorn i Rio de Janeiro, som uträttades med hjälp av ett multi-kriterieramverk. Ramverket består av fyra kategorier (potential, genomförbarhet, samt ekonomisk- och miljömässig prestanda), 14 nyckelområden samt 59 underfrågor. Ramverket användes för att assistera i insamlandet, strukturerandet och utvärderandet av information. En fältstudie på åtta veckor i Rio de Janeiro var en del av studien. Resultatet visar att ingen fullständig separering av organiskt avfall sker i Rio, vilket är orsaken till att studien inkluderar avfallsströmmarna blandat kommunalt avfall (som deponeras; benämns MSW) och delvis sorterat organiskt avfall (innehåller 85 % organiskt innehåll; benämns WHOC). Avloppsslam exkluderades från studien för att fokusera på fast kommunalt avfall. Potentialen och genomförbarheten är markant högre för MSW jämfört med WHOC, dock skall det understrykas att tillväxtpotentialen för WHOC är stor vilket ej framgår av siffrorna. Deponin mottager årligen nära 1.2 miljoner ton organiskt avfall (inkl. vatten) som ger en biogasutdelning på 140 miljoner Nm3 / år (50 – 55 % CH4); medan WHOC har en potential på 26 – 42 tusen ton (torrvikt) per år med en biogasutdelning på 6.6 – 19.5 miljoner Nm3 / år (55 – 63 % CH4). Genomförbarhetsanalysen för avfallsströmmarna visade att alla nyckelområden förutom ekonomiska instrument var värderade högre för MSW jämfört med WHOC. Studien visar vidare att det mest genomförbara användningsområdet för biogasen är injektion till gasnätet. Miljömässiga prestandan visar att substituering av naturgas med biogas kan sänka växthusgasutsläpp med 68 %, och för varje ton (torrvikt) av rötrester kan ca 8 kg fosfor och 36 kg kväve ersättas. Ekonomiska prestandan visar att biogasproduktion från deponi är mer kosteffektivt än i en bioreaktor, samt att ingen av biogaslösningarna är lönsamma, vilket kan väntas av en avfallshanteringslösning. Studien avslutas med att identifiera en rad utmaningar som biogassektorn i Rio ställs inför: en avsaknad på tillgång av biogas och ingen aktiv plan för att öka produktionen; ekonomiska utmaningar som indikerar ett behov av investeringsstöd; en brist på värdekedja för biogödsel. Resultatet av studien kan förhoppningsvis ge intressenter en bättre förståelse för vilka möjligheter och utmaningar som biogaslösningar ställs inför i Rio de Janeiro kommun – som i förlängningen kan öka möjligheterna för framgångsrika implementeringar av biogasprojekt i regionen.

Esta pesquisa tem como objetivo testar os critérios da técnica de Análise de Conteúdo Baseada em Critérios (Criteria-Based Content Analysis – CBCA) em relatos comuns de adultos, visando verificar quais critérios são mais frequentes em relatos verdadeiros. Trata-se de um estudo preliminar para futura elaboração de técnica de avaliação da credibilidade do testemunho, a ser utilizada para auxiliar as avaliações psicológicas das entrevistas realizadas nas perícias com adultos. Foram realizadas 46 entrevistas com relato livre e perguntas abertas com adultos a partir de 18 anos e escolaridade mínima de ensino médio, propondo-se 3 tarefas: 2 relatos (um verdadeiro e um falso) e a aplicação da Escala Fatorial de Neuroticismo - EFN. Na análise das entrevistas, obteve-se como resultados que os critérios “5: Descrições de interações” e “8: Detalhes não-usuais” são significativamente mais presentes nos relatos verdadeiros. Os resultados da EFN não mostraram diferenças significativas entre os participantes em função do nível de ansiedade. Os itens significativos para a verificação da credibilidade do testemunho poderão ser futuramente utilizados em novas pesquisas que explorem a análise das versões apresentadas à perícia criminal oficial durante a reprodução simulada dos fatos, após serem testados, em novas pesquisas específicas frente à veracidade na técnica pericial.<br>This research aimed to test the criteria of the Criteria-Based Content Analysis - CBCA technique in common reports of adults to ascertain which are the most frequent in true reports. It is a preliminary study to allow future elaboration of technical assessment of witness credibility to be used to assist psychological assessments in forensic interviews with adults. For this purpose, 46 free reports and open questions interviews with adults with minimum age of 18 years and at least high school education were made. Three tasks were proposed: to tell two stories (one true and one false) and to answer the Factorial Scale of Neuroticism - EFN. The analysis of the interviews showed that criteria “5: description of interactions” and “8: non-usual details” were significantly more frequent in true reports. The results of the EFN did not show significant differences among the participants based on the level of anxiety The significant items for checking the credibility of the testimony can be further explored in new research to explore the analysis of the versions presented to the crime scene investigators during reconstruction, after being tested in specific new research on expert technical veracity.

Sustainable transport is now a popular goal of transport planning. As with any aspiration, systems and mechanisms are required to assess and gauge success in achieving this policy goal. There is increasing reliance on sustainable transport indicators as appropriate tools for this purpose. The usefulness and credibility of any indicator-based assessment will undoubtedly depend on the specific indicators utilised. As such, indicators must be selected carefully to maximise their contribution to the sustainable transport decision making process. A review of current applications of sustainable transport indicators has revealed however, that they are typically selected in an ad hoc and arbitrary fashion. Development of a framework that facilitates transparent and systematic indicator selection would therefore represent a significant advance in transport research. In that regard, this thesis presents the Evaluative and Logical Approach to Sustainable Transport Indicator Compilation (ELASTIC), a methodological framework which provides a flexible, participatory and systematic mechanism for identifying and selecting key sustainable transport indicators. The output of ELASTIC is the Transport Sustainability Profile (TSP), a small un-aggregated suite of sustainable transport indicators which together can provide a snapshot of the sustainability of a transport system. Using various multi-criteria and statistical techniques, ELASTIC applies a robust process to evaluate and select indicators based on their analytical soundness and their relevance to key objectives of sustainable transport. A generic and transferable tool, ELASTIC is capable of application at different geographical scales as well as to non-transport sustainability assessment. For the purpose of this research, the framework is demonstrated through application to England, UK where the judgements of relevant Academics and Transport Planners are elicited and entered into the ELASTIC framework to systematically select a subset of 15 indicators from an initial set of 200. By disaggregating the sample of stakeholders into regional groupings, different context-specific suites of indicators for the regional groupings were also derived. The demonstration confirms ELASTIC to be an inclusive and practical approach to compiling a suite of sustainable transport indicators specific to context and which reflects the unique values of key stakeholders.

Software testing is important, but judging whether a set of software tests is effective is difficult. This problem also appears in the classroom as educators more frequently include software testing activities in programming assignments. The most common measures used to assess student-written software tests are coverage criteria—tracking how much of the student’s code (in terms of statements, or branches) is exercised by the corresponding tests. However, coverage criteria have limitations and sometimes overestimate the true quality of the tests. This dissertation investigates alternative measures of test quality based on how many defects the tests can detect either from code written by other students—all-pairs execution—or from artificially injected changes—mutation analysis. We also investigate a new potential measure called checked code coverage that calculates coverage from the dynamic backward slices of test oracles, i.e. all statements that contribute to the checked result of any test. Adoption of these alternative approaches in automated classroom grading systems require overcoming a number of technical challenges. This research addresses these challenges and experimentally compares different methods in terms of how well they predict defect-detection capabilities of student-written tests when run against over 36,500 known, authentic, human-written errors. For data collection, we use CS2 assignments and evaluate students’ tests with 10 different measures—all-pairs execution, mutation testing with four different sets of mutation operators, checked code coverage, and four coverage criteria. Experimental results encompassing 1,971,073 test runs show that all-pairs execution is the most accurate predictor of the underlying defect-detection capability of a test suite. The second best predictor is mutation analysis with the statement deletion operator. Further, no strong correlation was found between defect-detection capability and coverage measures.<br>Ph. D.

ABSTRACT Predicting On-the-Job Teacher Success Based on a Group Assessment Procedure Used for Admission to Teacher Education by LaVaun Gene Faulk, Doctor of Education Utah State University, 2008 Major Professor: Deborah Byrnes, Ph.D. Department: Elementary Education Students who have graduated in Elementary Education at Utah State University, since 1997 when the group assessment interview procedure was adopted, and have been employed as teachers for at least two years were contacted. Students were located with the help of the Utah State Office of Education (USOE) and the Office of Teacher Education, Graduation, and Educator Licensing at USU. Permission to interview each teacher’s supervisor was obtained from each study participant. Principals were contacted and interview dates set. A self-anchoring interview was conducted to provide quantitative data on the success of each teacher. This new data was then used to compare each participant’s success as seen by supervisors to existing data already on record at USU. Specifically, principal interview data were compared to the participant’s student teaching scores, prior academic achievement data (grade point average and American College Test scores), and ratings the teacher received on the group assessment interviews when applying to the elementary education teacher training program at USU.

The Blue Drop Incentive-based Regulation (programme) was introduced in 2008 by the Department of Water Affairs (DWA) with the aim of maintaining and improving drinking water quality in South Africa. The programme is being implemented in order to protect consumers from water services providers who might not act in the interest of the public. For some years the confidence level of the public regarding the quality of drinking water in South Africa has not been at the desired level. The programme involves annual assessment of water services authorities by the DWA. In order for water services authorities to be awarded the Blue Drop status they are required to comply 95% in terms of the criteria used in the assessments. During the first and second years of Blue Drop assessments a number of municipalities chose not to be assessed but quite a few achieved the Blue Drop status nationally. It is against this background that the researcher undertook a study to determine how water services employees in municipalities perceive the Blue Drop programme. To achieve the study objective the mixed method involving quantitative and qualitative methodologies was employed. Semi-structured interviews were conducted with supervisors and management while water treatment works employees completed a survey questionnaire. The qualitative and quantitative data analysis brought to light the following core findings: * The Blue Drop programme has the support of the overwhelming majority of employees who participated in the research. They perceive the programme as an inspiration for improved performance of the water services function in municipalities. * There is a lack of or poor understanding of the water sector legal framework including the Blue Drop assessment criteria by some participating employees. * There is a perceived lack of management and political leadership involvement and support for the water service function. Although the Blue Drop programme has been reported to be an excellent intervention by nearly all the participants, there are certain aspects that can be improved and are dealt with in the last chapter of the mini-dissertation.<br>Thesis (M Development and Management)--North-West University, Potchefstroom Campus, 2012

Measurement of visual quality is crucial for various image and video processing applications. It is widely applied in image acquisition, media transmission, video compression, image/video restoration, etc. The goal of image quality assessment (QA) is to develop a computable quality metric which is able to properly evaluate image quality. The primary criterion is better QA consistency with human judgment. Computational complexity and resource limitations are also concerns in a successful QA design. Many methods have been proposed up to now. At the beginning, quality measurements were directly taken from simple distance measurements, which refer to mathematically signal fidelity, such as mean squared error or Minkowsky distance. Lately, QA was extended to color space and the Fourier domain in which images are better represented. Some existing methods also consider the adaptive ability of human vision. Unfortunately, the Video Quality Experts Group indicated that none of the more sophisticated metrics showed any great advantage over other existing metrics. This thesis proposes a general approach to the QA problem by evaluating image information entropy. An information theoretic model for the human visual system is proposed and an information theoretic solution is presented to derive the proper settings. The quality metric is validated by five subjective databases from different research labs. The key points for a successful quality metric are investigated. During the testing, our quality metric exhibits excellent consistency with the human judgments and compatibility with different databases. Other than full reference quality assessment metric, blind quality assessment metrics are also proposed. In order to predict quality without a reference image, two concepts are introduced which quantitatively describe the inter-scale dependency under a multi-resolution framework. Based on the success of the full reference quality metric, several blind quality metrics are proposed for five different types of distortions in the subjective databases. Our blind metrics outperform all existing blind metrics and also are able to deal with some distortions which have not been investigated.

碩士<br>國立成功大學<br>臨床藥學與藥物科技研究所<br>105<br>Health technology assessment (HTA) is a comprehensive assessment of the clinical, economic, and social issues. Many countries established organizations of HTA to evaluate drug information by evidence-based approach. Multi-criteria decision analysis (MCDA), a structured approach that supports decision-makers to assess and compare multiple options among multiple dimensions and criteria, which can be applied in evaluation of insurance coverage and reimbursement. This study aims to establish a decision-making model with multiple criteria for appraisal and reimbursement, to compare viewpoints toward various dimensions and criteria from different stakeholders, and to evaluate the five targeted therapies for metastatic colorectal cancer. Criteria selection, weights and other information about the criteria and performances of targeted therapies were obtained by medical expert interview and questionnaire analysis. We interviewed 30 stakeholders for weighting of criteria and interviewed 10 clinical experts for scoring of options. This study found that most of the stakeholders take “clinical value” (especially “comparative effectiveness”) as the most important dimension (criteria). Overall, cetuximab has the highest value, followed by bevacizumab and panitumumab. This study is a pilot study, which use MCDA to conduct a comprehensive value assessment. The variations of weightings for dimensions and criteria from different stakeholders are reported. Both overall and specific performance of targeted therapies by dimensions, criteria and stakeholders are also evaluated. The findings of this study will be a base for developing further useful decision models to evaluate the comprehensive value of medicine in the future.

碩士<br>國立臺中教育大學<br>教師專業碩士學位學程<br>105<br>This study mainly explored the effects of "photographic instructional teaching" and "photography teaching" on sixth graders’ photographic knowledge, which included angle light, camera knowledge, and composition ratio; moreover, it also explored the difference of social interaction behaviors between two groups of students. Quasi experiment design was adopted to conduct this study. There are one hundred and ten sixth graders from four classes that participated in this study. They are divided into two groups: an experimental group of two classes and a control group of other two classes. The experimental group was arranged for photography standard teaching, and the control group was arranged for photo teaching. Both the experimental group and the control group accepted two-unit learning tasks of photography. The study applied heterogeneous grouping, group discussions and mutual assessment through respective network platforms and recorded dialogue to analyze interaction behaviors and interactional patterns, which was based on nine indicators of IBIS (Issue-based information system), to conclude the semantics of dialogue and then classify group-discussion patterns. The results of this study indicated: 1. Both photography standard teaching and general photography teaching help to enhance photographic knowledge and the capability of operation; the experimental group, which applied photography standard teaching, especially made a great progress on the knowledge of composition ratio. 2. The social interaction behaviors of peer-assessment feedback help to boost of team cooperation, and the relevant capabilities of in-depth discussion about the subject, but it is still essential to provide appropriate benchmarks and regulations, which can multiply learning effects. 3. Online collaboration platform is indeed helpful to group discussion, record keeping, and provides more time for feedback and reflection. As time passes, the tasks of different units can make more comparison of learning progress. 4. Information technology tools with photographic functions, such as cameras, tablet PCs and other equipment, can boost students’ interests. However, the students, who take multi-functions and simplicity of operation into account when they choose shooting tools, prefer the Tablet PC to the camera. 5. In addition to knowledge learned from the class, combination of practical feeling of surroundings will help students to immerse in the environment and shoot photographic works with better quality. 6. According to the social interaction behaviors between the experimental group and the control group, the cooperative discussion patterns can be concluded as "cooperation", "one to many", "less one or less", "non-interaction", and " two discussion among tree people". However, the students who accepted photographic instructional teaching could make more cooperation and explore the subject more deeply, which helps to boost their learning effects.

This thesis focuses on land degradation in the hinterland of Rio de Janeiro, part of the highly endangered Brazilian Atlantic Forest biome. Forest and pasture degradation are of outmost concern in the region. Thus, the main objective of this work is to provide a methodology to identify areas that fulfill the aim of increasing forest area, improving forest quality and reducing overall pasture degradation. Therefore, this work presents an approach for high-resolution land cover and pasture degradation mapping as well as an approach for prioritizing reforestation sites. Based on the prioritized land, forest scenarios are modelled and evaluated. Outcomes of this work include the recommendation to restrict land use on slopes above 10° and theoretical considerations to adapt compensatory payments for reforestation based on the priorities of the identified sites. Methods used in this work encompass image fusion using RandomForest regression, Land Cover Classification with the RandomForest classifier and Multiple Endmember Spectral Mixture Analysis (MESMA) and field methods for pasture degradation mapping.:LIST OF FIGURES XVII LIST OF TABLES XIX LIST OF ABBREVIATIONS XXI 1 INTRODUCTION 1 1.1 PROBLEM IDENTIFICATION 1 1.2 RESEARCH OBJECTIVES AND QUESTIONS 3 1.3 VALUE OF THE RESEARCH 5 1.4 STRUCTURE 6 2 CONCEPTUAL BACKGROUND 7 2.1 LAND DEGRADATION 7 2.1.1 Definition of Land Degradation 7 2.1.2 Forest Fragmentation 9 2.1.3 Pasture Degradation 14 2.2 REMOTE SENSING FUNDAMENTALS 16 2.2.1 Optical Remote Sensing 16 2.2.2 Image Classification and Land Cover Mapping 20 2.2.3 Vegetation Discrimination 22 2.2.4 Digital Elevation Model (DEM) Applications 24 2.3 LANDSCAPE METRICS 25 3 STUDY AREA 27 3.1 LOCATION 27 3.2 PHYSICAL ENVIRONMENT 28 3.3 HUMAN ENVIRONMENT 32 4 PART (A): STATE OF THE ART 39 4.1 LAND DEGRADATION IN THE GUAPI-MACACU WATERSHED 40 4.1.1 Forest Fragmentation 40 4.1.2 Pasture Degradation 42 4.2 REMOTE SENSING-BASED LAND DEGRADATION ASSESSMENTS 46 4.2.1 Forest Monitoring in the Brazilian Atlantic Forest Biome 49 4.2.2 Pasture Degradation Mapping 51 4.3 POLICIES AND PROGRAM WITH RELEVANCE TO CONSERVATION AND REFORESTATION PROJECTS IN BRAZIL 54 4.3.1 International Programs, Schemes and Intitiatives 54 4.3.2 National Environmental Policies and Programs 58 4.3.3 Policies and Programs with Focus on the Brazilian Atlantic Forest 64 4.3.4 State-based Regulations in the Rio de Janeiro Federal State 65 4.4 LAND REHABILITATION AND REFORESTATION EFFORTS IN THE RJ FEDERAL STATE 66 4.4.1 Pasture Rehabilitation 66 4.4.2 Forest Restoration 67 5 MATERIAL AND METHODS 71 5.1 GEODATA AND SOFTWARE 71 5.2 PART (B): LAND COVER AND PASTURE DEGRADATION MAPPING 73 5.2.1 Field Survey of Degraded Pastures 73 5.2.2 Satellite Data Processing 75 5.2.3 Hot Spot Analysis 86 5.2.4 Relation of Slope Angle and Degradation Class 87 5.3 PART (C): PRIORITIZATION OF REFORESTATION SITES 87 5.3.1 Preliminary Study 88 5.3.2 Spatial Multi-Criteria Evaluation (SMCE) 90 5.3.3 Forest Scenario Development and Evaluation Using Landscape Metrics 94 6 RESULTS 97 6.1 PART (B): MAPPING OF PASTURE DEGRADATION 97 6.1.1 Categorization of Pasture Degradation 97 6.1.2 High-resolution SWIR band modelling 99 6.1.3 Land Cover Classification with Random Forests 101 6.1.4 Pasture Degradation Mapping Using Spectral Mixture Analysis and Field Data 103 6.1.5 Hot Spot Analysis of Pasture Degradation 106 6.1.6 Slope Influence on Pasture Degradation 107 6.2 PART (C): PRIORITIZATION OF REFORESTATION SITES USING SMCE 109 6.2.1 Characteristics of the Prioritized Areas 109 6.2.2 Forest Scenarios 113 7 DISCUSSION 117 7.1 PART (A/B): ASSESSMENT OF THE STATUS OF LAND DEGRADATION IN THE GUAPI-MACACU WATERSHED 117 7.2 PART (B): METHODOLOGICAL APPROACH FOR PASTURE DEGRADATION MAPPING 119 7.2.1 Satellite images for high-resolution LCC 119 7.2.2 High-resolution SWIR Band Modelling 120 7.2.3 Land Cover Classification 121 7.2.4 Pasture Degradation Mapping Approach 122 7.3 PART (C): SPATIAL PRIORITIZATION FOR REFORESTATION MEASURES 125 7.3.1 Identification of Priority Sites 125 7.3.2 Forest Scenarios 127 8 CONCLUSION AND RECOMMENDATIONS 131 9 OUTLOOK 135 REFERENCES 137 ANNEX I<br>Die vorliegende Arbeit befasst sich mit der Landdegradation im Hinterland von Rio de Janeiro, Teil des stark gefährdeten brasilianischen Atlantikwaldbioms.

Faculty of Health Science SChool of Public Health 0112677r burmamtk@iafrica.com<br>The study aimed to evaluate IMCI guidelines, developed to assess children with Suspected Symptomatic HIV [SSHIV] as a screening tool for AIDS. OBJECTIVES 1. To look at the agreement between IMCI classification for SSHIV and WHO clinical case definition for AIDS using a retrospective record review of the same hospitalised children. 2. To determine the sensitivity, specificity, positive predictive values and likelihood ratios of the IMCI SSHIV criteria (Guidelines 2001), WHO clinical case definition for paediatric AIDS and Bloemfontein Proposed simplified case definition for paediatric SSHIV, using HIV ELISA results in children older than 15 months as a gold standard. METHODS The study involved 304 children in the IMCI age range who were admitted to the Edenvale Hospital during the study period and who met all the inclusion and exclusion criteria. These children were assessed with IMCI criteria and WHO criteria for AIDS. [Objective 1] The findings of 50 children above 15 months of age with ELISA results were compared using 3 sets of criteria. [IMCI, WHO and Bloemfontein proposed simplified case definition for paediatric SSHIV] [Objective 2] FINDINGS IMCI and WHO criteria for AIDS were the same in 158 [52%] of the 304 children. Almost all [22 out of 23 children] with WHO criteria for AIDS were also classified by IMCI criteria as Suspected Symptomatic HIV. [Objective 1] v IMCI criteria had the highest sensitivity [85.7%], while WHO criteria had the highest specificity [88%] based on ELISA results. [Objective 2] CONCLUSION Based on the above findings, IMCI criteria could be considered as a screening tool to select children aged 15 months and above for appropriate laboratory investigation for HIV infection confirmation in remote areas. WHO criteria for AIDS could be considered for exclusion of AIDS in children aged 15 months and above in remote areas where laboratory facilities are not available. In this study, reliable findings could not be obtained in children younger than 15 months.

Mathematics, as a subject, is used in various scientific careers as a selection tool. It is regarded as the cornerstone of scientific literacy. However, since learners in South Africa do not perform optimally in mathematics they do not enjoy international recognition. Education renewal is ongoing, and South Africa currently follows an outcomes-based (OBE) approach. The teaching of mathematics cannot be renewed successfully if assessment methods are not regularly adapted to meet new developments in the field. The incorporation of an OBE approach at school level made it necessary to facilitate assessment renewal in tertiary mathematics at the Tshwane University of Technology (TUT). TUT is engaged in a merger of three institutions, which has made the development of new curricula and teaching material essential. Hence this a perfect time to introduce assessment renewal. The primary purpose of this thesis is to report on the research study and its results, and to make recommendations for improving the practice. The overarching research hypothesis in this study is that a suitable assessment would probably enhance the effectiveness of a student’s learning. The research focused on the following questions: -- To what extent are outcomes-based strategies effectively and regularly introduced in the teaching of mathematics at TUT? -- Will tertiary mathematics facilitators be prepared to implement outcomes-based strategies at TUT? -- To what extent are outcomes-based strategies strategies in subjects supported by mathematics implemented at TUT? -- How does the ecology of TUT affect the implementation of outcomes-based strategies? -- What other factors could influence the level of implementation of OBS at TUT? -- Have any of the mathematics facilitators at TUT received suitable and adequate training in the implementation of outcomes-based strategies? -- What are the possible implications of the study for TUT’s assessment policy? Action research was chosen as the research design because it is ideally suited to improving practice. Quantitative and qualitative data were collected through questionnaires, personal interviews, interviews with focus groups, observations, documentation and a reflective diary. The main findings are as follows:– -- OBE strategies are not being introduced throughout TUT in the teaching of mathematics. -- Group work and peer assessments are rare occurences. -- Some lecturers are convinced that new assessment methods would lower the standard of their teaching. -- Uncertainty about the merger and the varying teaching conditions at the different campuses tend to inhibit lecturers, making them less willing to undertake assessment renewals. -- TUT should review its admission criteria. -- The lecturers cited large class groups, a lack of marking assistance and ignorance about OBE as reasons for failing to undertake assessment renewal. The study prepared respondents for assessment renewal. In the interim, however, TUT has introduced a Policy on Teaching, Learning and Technology, whereby OBE has been selected as the teaching model for TUT. In future, respondents will receive training and guidance in the implementation of OBE. This study has hopefully made a significant contribution to this positive development.<br>Thesis (PhD (Curriculum Studies))--University of Pretoria, 2007.<br>Curriculum Studies<br>unrestricted

The aim of thesis is to evaluate the current practice of assessing the credibility of testimony in criminal proceedings and reflect on its current issues. In particular, it is necessary to resolve the question of the extent to the competence of an expert-psychologist in assessing process and the establishment of basic criteria according to which the experts proceed. I have chosen this topic because it's connecting criminal law and psychology which is important for society and a highly discussed in this time. Assessing the credibility is one of usual requests for expert psychologists from investigative, prosecuting and adjudicating bodies and it is also the most common, but often the most difficult part of psychological expertise. The thesis is composed of four chapters. The first chapter deals with the history of assessing the credibility. The second chapter describes the psychological expertise in criminal proceedings in our country and consists of four parts dealing with experts, expertise and evidence and evaluation of evidence in criminal procedure. The third chapter looks at assessing the credibility as a problem of professionals and it contains four parts. The first part defines the basis for assessing the credibility, the second part defines fundamental terms. The third part describes verbal and...

Petroleum refineries emit a variety of airborne substances which may be harmful to human health. HEIDI II (Health Effects Indicators Decision Index II) is a computer-based decision analysis tool which assesses airborne emissions from Canada's oil refineries for reduction, based on ordinal ranking of estimated health impacts. The model was designed by a project team within NERAM (Network for Environmental Risk Assessment and Management) and assembled with significant stakeholder consultation. HEIDI II is publicly available as a deterministic Excel-based tool which ranks 31 air pollutants based on predicted disease incidence or estimated DALYS (disability adjusted life years). The model includes calculations to account for average annual emissions, ambient concentrations, stack height, meteorology/dispersion, photodegradation, and the population distribution around each refinery. Different formulations of continuous dose-response functions were applied to nonthreshold-acting air toxics, threshold-acting air toxics, and nonthreshold-acting CACs (criteria air contaminants). An updated probabilistic version of HEIDI II was developed using Matlab code to account for parameter uncertainty and identify key leverage variables. Sensitivity analyses indicate that parameter uncertainty in the model variables for annual emissions and for concentration-response/toxicological slopes have the greatest leverage on predicted health impacts. Scenario analyses suggest that the geographic distribution of population density around a refinery site is an important predictor of total health impact. Several ranking metrics (predicted case incidence, simple DALY, and complex DALY) and ordinal ranking approaches (deterministic model, average from Monte Carlo simulation, test of stochastic dominance) were used to identify priority substances for reduction; the results were similar in each case. The predicted impacts of primary and secondary particulate matter (PM) consistently outweighed those of the air toxics. Nickel, PAH (polycyclic aromatic hydrocarbons), BTEX (benzene, toluene, ethylbenzene and xylene), sulphuric acid, and vanadium were consistently identified as priority air toxics at refineries where they were reported emissions. For many substances, the difference in rank order is indeterminate when parametric uncertainty and variability are considered.

<p>The Lake Bosomtwe impact crater is located in the Ashanti region of Ghana, West Africa. The impact crater diameter from rim to rim is approximately 10.5 km wide with a lake located at the center. Three different districts touch the lake containing 155,000 hectacres of land. There are approximately 7,500 people from 24 villages, and 12 of those villages reside within walking distance of the lake shore. Within the last ten years, the lake has been subjected to overfishing and environmental degradation. The health of the lake has declined due to overfishing and algae blooms caused by improper fertilization rates. Because of these factors, residents of the area have been forced to transition to subsidence farming as their main vocation. According to the Ghana Statistical Service group, 97.6% of the population participates in some form of rural crop farming (Ghana Statistical Service, 2010). Experience with common practices such as crop rotation, fertilizer use, and erosion control is extremely limited. The lake has not been recommended for recreational use due to the excess runoff in the form of agrochemicals, liquid, and organic waste. Caged aquaculture and traditional fishing within Lake Bosomtwe is currently illegal.</p><p><br></p><p>A comprehensive Institutional Review Board (IRB) survey was developed for the six primary research questions to be examined. From these six research questions, 147 specific questions were developed. Three of the 147 questions were to obtain Global Positioning System (GPS) data for community households, pit latrines, and water wells or boreholes. This study sought to interview 10-15 farmers per village, for each of the 12 villages located along the shore of Lake Bosomtwe of their perspective on land use change/cover in the Lake Bosomtwe area, current farming practices, current water sanitation and hygiene practices, and current fishing practices. These surveys were collected in the form of oral responses, for which 118 small-holder farmers were interviewed. Of the participants surveyed, 66% were qualified to answer all questions, and 100% of participants completed the survey.</p><p><br></p><p>Some specific statistical tests were conducted based of market assessment survey. It was determined that no association between gender and level of education existed. Meaning, that female participants interviewed have just as many opportunities as male participants to pursue education beyond Junior High School (JHS). Yield averages between the villages on the north side of the lake with road access and villages on the southern portion of the lake with limited to no road access were determined to be significantly different. It was determined that road access does affect village yield. When comparing average usable yields between villages located on the northern side of the lake with road access or between villages on the southern side of the lake with limited to no road access, these results were not statistically significant. No significant difference in the scores for villages with road access on the northern side of the lake and villages with limited to no road access on the southern side of the lake existed. Therefore, road access does not affect village usable yield. Through statistical analysis an association was determined between people who practice bathing and washing in the lake and those who practice fishing as a form of livelihood.</p><p><br></p><p>Four decision matrices were created to prioritize the following items: Farm Components, technologies to showcase at an appropriate technology center, improved farming practices to showcase through Demonstration Plots, and extension outreach topics. The top three results for the Farm Components were: Appropriate Technology Center (ATC), Demonstration Plots, and a Micro-Credit Union. The top three technologies to showcase as part of the ATC are: PICS Bags, Moisture Meters, and Above-Ground Aquaculture. The three demonstration plots recommended terracing/erosion control, crop rotation, and cover crops. The highest priority extension outreach topics were: basic home/farm finance, improving health through washing stations, and post-harvest loss prevention. The top three priorities of each decision matrix will be the focus of further study, so that these topics can be developed and programs focusing on these needs can be implemented in collaboration with the community partners.</p>

Text in Afrikaans<br>Summaries in Afrikaans and English<br>This study aims to investigate and explain how the L2 -facilitator can effectively employ the various facilitation skills of language teaching in Afrikaans Second Language within the Outcomes Based Education framework in the learner-centred classroom. The facilitator is critical in providing an opportunity for multicultural learners to develop the necessary language learning skills to enjoy Afrikaans Second Language/Additional Language learning as an interesting learning experience within a positive learning milieu. In the learner-centred U -classroom, learners too must accept responsibility for their own and their peers' learning within the co-operative learning group. This study reveals how the L2 -facilitator can develop the necessary knowledge and skills concerning groupwork, such as the strategies enhancing L 2 -learning, effective group facilitation skills, learner attitudes towards the facilitator, problem-solving skills, co-operative learning as a control technique, communication, learners' behaviour and the advantages of groupwork. Furthermore, elements of classroom negotiation and the facilitator's methods of working in this negotiated partnership are also discussed. Since language learning is integral to lifelong learning, multicultural learners must be motivated to learn Afrikaans Second/ Additional language with greater enthusiasm. This necessitates the L2 -facilitator creating an interesting, challenging and authentic language learning environment where mutual respect and trust are emphasised. This study reveals how the L2 -facilitator could develop his/her knowledge of task-based L2 -teaching and use it with the effective techniques of facilitation and negotiation skills in the taskorientated second language classroom to lead learners to effective Afrikaans L2 -learning. The new National Language Standardisation Policy 200112002 necessitates the facilitator of Afrikaans L 2 -teaching/learning within the Outcomes Based Education framework and the revised Curriculum 2005 to be aufait with assessment and his/her role in assessment. Being knowledgeable on the various criteria and strategies regarding assessment is therefore imperative. Finally, chapter five illustrates practically how the facilitator could plan, organise, base, integrate and present authentic Afrikaans L 2 -lessons/work based on the theoretical knowledge and aspects of facilitation skills, group-work, task-based learning and assessment discussed in chapters two to four.<br>Daar word in die studie gepoog om te ondersoek en te verduidelik hoe die T2-fasiliteerder die verskillende fasiliteringsvaardighede ten opsigte van T2 -Afrikaansonderrig binne die UGO -raamwerk in die leerdergesentreerde T2-klaskamer effektief kan gebruik. Die fasiliteerder behoort sy multikulturele leerders die geleentheid te gun om die nodige taalleervaardighede te ontwikkel sodat hulle Afrikaans Tweedetaalleer/ Addisionele Taalleer as 'n interessante leerervaring binne 'n positiewe leerklimaat kan geniet. In die leerdergesentreerde T2 -klaskamer moet die leerders ook die verantwoordelikheid vir bulle eie leer, en vir die leer van ander leerders binne kooperatiewe leergroepe kan aanvaar. Die wyse waarop die fasiliteerder van T2-leer die nodige kennis en vaardighede ten opsigte van groepwerk kan ontwikkel, word deur die studie aan die lig gebring. Die verskillende strategiee wat die aanleer van die tweedetaal binne groepwerk bevorder, effektiewe groepsfasiliteringsvaardighede, leerders se gesindhede teenoor die fasiliteerder, die probleemoplossingsvaardighede, kooperatiewe leer as beheertegniek, kommunikasie, leerdergedragswyses en die voordele van groepwerk kom aan bod. Elemente van klaskameronderhandeling en die fasiliteerder se werkswyse in die onderhandelingsvennootskap word ook bespreek. Aangesien taalleer 'n integrale faset van lewenslange leer vorm, moet multikulturele leerders gemotiveer word om Afrikaans Tweedetaal/ Addisionele Taal op 'n meer entoesiastiese wyse te kan leer. Die T2 -fasiliteerder moet 'n interessante, uitdagende, outentieke taalleeromgewing skep waarin wedersydse respek en vertroue beklemtoon word. Die studie toon die wyse aan waarop die T2 -fasiliteerder sylhaar kennis in verband met taakgerigte T2 -onderrig kan ontwikkel en dit met die effektiewe fasiliteringstegnieke en onderhandelingsvaardighede in die taakgeorienteerde T2-klaskamer kan kombineer en gebruik om leerders tot effektiewe T2 -Afrikaansleer/ Addisionele Taalleer te kan lei. Die nuwe Nasionale Taalstandaardiseringsbeleid 2001/2002 vereis dat die fasiliteerder van T2-Afrikaansonderrig/-leer binne die UGO -raamwerk en die hersiene Kurrikulum 2005 deeglike kennis moet dra van assessering en sylhaar rol in assessering. Deeglike kennis ten opsigte van die verskillende assesseringskriteria en assesseringstegnieke is dus noodsaaklik. Daar word in hoofstuk vyf aangetoon op watter wyse die fasiliteerder outentieke praktiese T2-Afrikaanslesse/-werk, kan beplan, organiseer en dit op die teoretiese kennis en aspekte ten opsigte van fasiliteringsvaardighede, groepwerk, taakgerigte leer en assessering wat in hoofstukke twee tot vier bespreek word, kan toepas en geintegreerd kan aanbied.<br>Afrikaans and Theory of Literature<br>D.Litt. et Phil.
