Every year billions of dollars are spent on development aid and training around the world. However, only 10% of this training results in the transfer of knowledge, skills, or behaviors learned in the training to the work place. Ideally, learning transfer produces effective and continued application by learners of the knowledge and skills they gained through their learning activities. Some studies suggest that technology usage can serve as an effective post-learning intervention to enhance the transfer of learning.

Currently, there is a limited body of research examining the factors that hinder and promote learning transfer in professional development, particularly the professional development of school leaders in developing countries. This qualitative exploratory study sought to address the gap in the literature by examining 6 schools, 3 in Burkina Faso and 3 in Ghana, West Africa. This investigation explored: (a) if and how learning transfer took place after the leadership training; (b) what promoted and hindered learning transfer in both countries; and (c) if the use of a text message intervention after the training enhanced learning transfer. The sample consisted of 13 West African school leaders (6 in Burkina Faso and 7 in Ghana) who attended a 3-day leadership training workshop. Data collection included in-depth interviews, document analysis, post-training site visits, and text messages to ascertain whether this mobile technology intervention enhanced learning transfer.

The findings demonstrate that learning transfer occurred in both countries in all six schools. Data indicate that most of the transfer of learning happened in areas not requiring mindset and behavioral changes. Data suggest that the facilities in which the trainings took place, the facilitators’ dispositions and knowledge as well as the adequacy of the materials and the follow-up of the mobile text messaging intervention assisted the participants in transferring knowledge to their schools following the training. Participants also indicated some inhibitors to the transfer of learning such as financial, cultural, and human behavior constraints. This study helps increase our understanding of what promotes and inhibits learning transfer in educational settings in developing countries and provides suggestions for trainers and teachers who facilitate trainings.

ENGLISH ABSTRACT: The Democratic South African government inaugurated in 1994 identified the need for intermediate skills that are required to contribute to the growth of the economy and to reduce the high unemployment rate. Further Education and Training Colleges (FETC) were established after 1994 by merging the former 152 technical colleges into 50 FETCs. The function of these FETCs was to offer intermediate skills to the youth, women, and employed and unemployed South Africans. The South African government introduced a number of strategies, Acts and policies to support the colleges and to implement demand-driven intermediate skills programmes which would close the skills gap and improve the growth of the economy. These policies seek to ensure that skills offered at colleges are aligned to the needs of industry and to make sure that the college programmes will be in demand in the work place. The study presented is aimed at investigating this alignment by evaluating how apprentices in the final stage of their vocational training perform and meet the demands at their work places. A number of strategies used by different countries to support and develop their education systems are discussed. The discussion is directed at considering how vocational education ensures a positive contribution to skills development and what its impact is on the growth of the economy. This study provides a comprehensive policy and legislative framework which governs and supports the higher education institutions and the FETCs. The study was designed to determine whether welding apprentices from the College are, according to the work place staff and management and stakeholder bodies, appropriately equipped with vocational skills and knowledge to execute their duties at the work place. The evaluation and analysis of the data extracted from the responses of the interviews and questionnaires are presented and discussed. The results enabled the researcher to conclude that the evaluation of apprentice performance at the work place provides significant insight into the question of how vocational training and knowledge at the WCFETC meet the demands at the work place. Conclusions are drawn and recommendations are made.
AFRIKAANSE OPSOMMING: Die demokratiese Suid-Afrikaanse Regering, wat in 1994 ingehuldig is, het die behoefte aan intermediêre vaardighede om die groei van die ekonomie en die van die hoë werkloosheidssyfer te verlig, geïdentifiseer. Verdere Onderwys en Opleiding Kolleges (VOOKS) is na 1994 totstand gebring deur die samesmelting van 152 voormalige Tegniese kolleges tot 50 VOOKS. Die funksie van die Verdere Onderwys en Opleiding Kolleges was om intermediêre vaardighede aan die jeug, vrouens en Suid-Afrikaners in diens of werkloos, te verskaf. Die Suid-Afrikaanse Regering het ´n aantal strategieë, wette en beleidsrigtings aangeneem om die kolleges te ondersteun en om die aanvraag-gedrewe intermediêre vaardigheidsprogramme te implementeer wat dan die vaardigheidsgaping sou vernou en die groei van die ekonomie sou bevorder. Hierdie beleidsrigting beoog om te verseker dat vaardighede wat by die Kolleges aangebied word, belyn is met die industrie as ook om te verseker dat die kollege programme benodig word in die werksplek. Die studie is gemik daarop om hierdie belyning te ondersoek en te evalueer hoe vakleerlinge in die laaste stadium van hulle ambagsopleiding vaar, en voldoen aan die eise van die werksplek. ´n Aantal strategieë wat deur verskillende lande gebruik word, om hulle eie opvoedingsstelsels te ontwikkel, word bespreek. Die bespreking verwys na hoe ambagsopvoeding ´n toevoeging tot vaardigheidsontwikkeling kan verseker en wat die impak daarvan op die groei van die ekonomie het. ´n Alomvattende beleid en ´n wetsraamwerk, wat Hoër OpvoedingsInstansies en die Verdere Onderwys en Opleiding Kolleges beheer en ondersteun, word verskaf. Die studie is ontwerp om te bepaal of die sweis vakleerlinge van die kollege, volgens die werksplek personeel en -bestuur en belanghebbende liggame, toepaslik toegerus en bevoeg is met ambagsvaardighede en kennis om die pligte van die werksplek uit te voer. Die evaluering en analise van die data, afgelei van die terugvoering van die onderhoude en vraelyste, word weergegee en voledig bespreek. Die resultate stel die navorser in staat om tot die gevolgtrekking te kom dat die evaluering van vakleerling-werksverrigting by die werksplek merkbare insig tot die vraag hoe ambagsopleiding en kennis by die Weskus VOOK aan die eise van die werksplek voldoen. Gevolgtrekkings en aanbevelings word aangebied.

Knowledge of the chemical composition of marine macroalgae is important to understand their nutritional value for abalone as well as their potential as a source of protein, carbohydrate and lipid for commercial use. This study investigates the seasonal variations in chemical composition and nutritive value of Ecklonia maxima collected from various kelp beds near commercial abalone farms on both the west and south west coasts of South Africa. It has been suggested by numerous abalone farmers that west coast kelp is not as good as the south west coast for abalone feed.

The objectives of this thesis were to i) determine the energy expenditure of draught oxen performing common farm operations, ii) establish the relationships between work on intake and digestibility of feeds by draught oxen, iii) investigate the effect of body condition before work and live weight losses during work on work output, and iv) investigate the implications of heat stress on draught oxen in semi-arid areas. The ultimate aim of this study was to generate information necessary for the design of feeding and working strategies for draught animals in semi-arid areas. To meet these objectives four experiments were conducted at the ICRISAT Sahelian centre, with the collaboration of the International Livestock Centre for Africa. In the first experiment the Oxylog, a portable breath by breath gas analyser, was used on 7 animals to determine their standing metabolic rate, their energy cost of walking on soils of different consistencies, and their efficiency of doing work, i.e. ploughing and carting. The average standing metabolic rate of animals was 487 (± 10.6) kJ/kg LW^0.75. The consistency of the soil on which animals were working had a marked effect on their energy cost of walking which was 1.59 (±0.069), 2.15 (±0.084) and 1.0 (±0.10) J/m/kg live weight on unploughed land, ploughed land and laterite tracks, respectively. The efficiency of ploughing sandy soils was 0.32 and was not significantly different from the efficiency of carting with different loads. The efficiency of doing work was not influenced by the type of work performed, the draught force exerted or the walking speed. In the second experiment intake of millet stover, water intake, live weight, plasma concentrations of T3, T4 and urea-nitrogen were measured on 18 animals that worked for 0, 2 or 4 h/day in sequence during three 3-week experimental periods. In addition to these variables, the digestibility and rate of passage of feeds through the digestive tract were measured during the third experiment on 12 animals working either 0, 2.5 or 5 h/day in sequence during three 2-week experimental periods. In the fourth experiment feed intake was measured on 18 animals of different body condition that worked 4 days a week for 7 weeks. The absence of effect of work on intake of millet stover was consistent during these experiments. The efficiency of utilisation of eaten roughages and the rate of passage of the digesta in the gastro-intestinal tract were not influenced by work either. This suggests that the nutrient supply from intake of roughages by working oxen and bulls is unlikely to be sufficient to compensate for the extra energy expended during work. Feed intake was however significantly affected by the quality of the millet stover fed and by the body condition of the animal.

Effects of corn processing with or without the inclusion of wet corn gluten feed (WCGF) on growth and performance were analyzed in two experiments. Treatments for both experiments were a diet including 47% whole-shelled corn (WSC) with no WCGF (WSC/0WCGF), a diet including 29% WSC with 30% WCGF (WSC/30WCGF), a diet including 47% dry-rolled corn (DRC) with no WCGF (DRC/0WCGF), and a diet with 29% DRC with 30% WCGF (DRC/30WCGF). Exp. 1 used 279 crossbred calves (230 kg) that were allocated to treatments in a 2x2 factorial completely randomized block design. No corn processing effects (all P > 0.31) were observed. Final BW was increased when WCGF was included in the diet (P = 0.03). ADG was increased for diets with WCGF (P = 0.03). Efficiency was not affected by the incorporation of WCGF in the diet. Digestibility of DM (P = 0.006) and starch (P = 0.009) was increased by the dietary inclusion of WCGF. There were no benefits observed for processing corn, but including WCGF at 30% (DM) increased gains and overall performance. Exp. 2 was a digestibility experiment using 5 ruminally cannulated Holstein heifers (248 ± 13 kg BW) in a 4 × 4 Latin square with an additional animal that was administered the same treatment sequence as another heifer on trial. No corn processing effects were observed for DM, starch, and ADF intake (all P ≥ 0.09). Dietary WCGF inclusion increased starch, non-starch and ADF intake (all P ≤ 0.01). Digestibility of DM, starch, non-starch, and ADF was not affected by corn processing, but DM, non-starch, and ADF digestibility were increased by WCGF inclusion in the diet (P ≤ 0.03). Ruminal pH was not affected by corn processing (P = 0.90) or dietary WCGF inclusion (P = 0.09). No corn × WCGF interactions were detected. There also was no difference among VFAs or total VFA concentration (all P ≥ 0.12) for corn processing effects. Passage rate (%/h) and ruminal liquid volume was not affected by corn processing or dietary WCGF inclusion (all P ≥ 0.66).

Wet corn gluten feed (WCGF) is commonly included in lactation rations for dairy cattle. Research at Kansas State University has shown that increasing WCGF inclusion decreased ruminal pH. Lack of adequate particle size may result in this decrease and can impact efficiencies, animal health and longevity. A study was conducted to look at the effects of feeding WCGF while maintaining > 10% of particles > 19 mm across diets. We hypothesized that as WCGF increased, DMI and milk yield would increase while ruminal pH would be maintained. Seven ruminally-cannulated, lactating Holstein cows were used in an incomplete 4 × 4 Latin square design with treatments of 0, 12.4, 24.5 or 35.1% WCGF across 4 periods of 21 d. Alfalfa hay was used to maintain particle size. All diets met particle size goals; however, as WCGF increased, the proportion of particles > 19 mm decreased (P = 0.01) and cows changed their sorting behavior in favor of particles > 19 mm (P = 0.03) and against particles on the bottom screen (P < 0.01) and pan (P = 0.01). As WCGF increased, ruminal pH and ECM/DMI were not affected, yet DMI (P = 0.02) and milk yield (P = 0.02) increased quadratically. Milk protein, lactose and fat concentrations were not affected; however, milk protein (P = 0.004; linear) and lactose (P = 0.02; quadratic) yields increased. In a separate study, active dry yeast (ADY) products, commonly used in the dairy industry to support ruminal health, were evaluated for product guarantees and effects of storage and storage medium. Few products received through normal distribution met product guarantees (1 of 6; experiment 1) and after 3 mo of storage cell viability dropped significantly (P < 0.01). In the second experiment, products were stored in ground corn or in a vitamin-trace mineral mix (VTM). Depressions in viability caused by high-temperature storage were partially mitigated when ADY products were stored with a VTM. Although both mediums resulted in lower cell viabilities after storage at 40ºC, VTM cell viabilities were significantly (P = 0.02) higher than ground corn.

The present era in South Africa is one that is marked by substantial change due to unparalleled advancement in the field of technology, globalisation and competitive markets. These changes have placed new demands on the education sector in South Africa, especially further education. In 2000/1 South Africa's Further Education and Training (FET) sector has been rejuvenated through a process of transformation when 152 former Technical Colleges and Colleges of Education merged to form 50 multi-campus FET Colleges. The rationale behind this merging process is to curb the serious skills shortage which is threatening economic growth in this country through offering vocational education and training; and to raise quality in the education sector. This re-engineering process in education is founded on principles of equity, human rights, democracy and sustainable development. Change, however, is also about people and their ideas, fears, capacity and ability to stand and work together towards a more prosperous future for all. Transformation or change such as with mergers is dependent on employees' total commitment towards realising the organisation's objectives. High levels of organisational commitment tend to encourage loyalty, higher levels of productiveness and general job satisfaction. For change initiatives to be successful though, communication across all hierarchical levels is of the utmost importance. Management is expected to provide employees with just treatment, provide acceptable working conditions, clearly communicate what is regarded as a fair day's work, and give feedback on how well the employee is doing. Employees, in return, are expected to clearly show a good attitude, follow directions and be loyal towards x the organisation. The psychological contract is utilised to investigate the scope of change in an employment relationship. The psychological contract is a contract setting out mutual expectations between employer and employee - a contract that forms the backbone of any new relationship such as with a merger. The researcher makes use of the psychological contract (by utilising the Tilburgse Psychologisch Contract Vragenlijst (TPC)) to explain employer obligations; violation of employer obligations; employee obligations; relational/transactional contract values; commitment; intention to leave; and change perceptions. Should either employment party not fulfill its contractual terms in any way, the psychological contract will be breached or violated and the employee might attempt to balance the situation by reducing his or her job efforts, badmouthing the organisation, resorting to absenteeism or even petty theft. The worst case scenario in this destructive process is that the employee might leave the organisation. The purpose of this research study is to determine the effect (if any) that the mergers might have had on the psychological- and employment contracts in the four FET Colleges that have remained in the Free State Province. A cross-sectional survey design was used to reach the objective of this research and an English translation of the aforementioned questionnaire (TPC) was randomly distributed amongst the total population of 375 employees at the Free State FET Colleges involved in this study. A response rate of 53% (n = 200) was achieved. Results from other authors who have used the TPC Questionnaire in their research offer support for the validity and reliability of the scales used. The statistical analysis was carried out with the SPSS program (SPSS, 2006), a program that is used to conduct statistical analysis regarding reliability and validity of the measuring instruments, descriptive statistics, t-tests, analysis of variance, correlation coefficients and multiple regression analysis. XI In Article 1 the researcher focused on the effect of mergers with regard to the influence of communication on the psychological contract as a possible factor affecting the intention to qUit. A multiple regression analysis (with intention to quit as dependent variable; and employer obligations, employee obligations, and communication as independent variables) was performed and 22.2% of the variance in intention to quit is predicted by communication and employee obligations (F = 28.07, p< 0.01). A practically significant correlation coefficient (p < 0.01) of a medium effect (r > 0.30) exists between communication and relational/transactional values and between communication and intention to quit. In Article 2 the effect of mergers, workplace changes and the violation of employer obligations on the psychological contract were evaluated, with special reference to job satisfaction and organisational commitment. In the above article a practically significant correlation coefficient (p < 0.01) of a medium effect (r> 0.30) was found between • change and job satisfaction; • job satisfaction and: commitment, employer obligations, employer violations; • commitment and: employer obligations, employer violations; and • employee obligations and: employer obligations, employer violations. A multiple regression analysis (with job satisfaction as dependent variable; and employer violation, organisational commitment, and change as independent variables) was performed and 29.9% of the variance in job satisfaction is predicted by employer violations, change and commitment (F = 27.668, p< 0.01). Recommendations for the organisation as well as for future research were made.

The transition from gestation to lactation requires numerous physiological and metabolic adaptations in order for the body to maintain relative homeostasis. For the modern dairy cow, the difficulty to meet these challenges is increased many-fold due to the large demand for energy and metabolites placed on the body by the high producing mammary gland. Milk fever or periparturient hypocalcemia can be defined as a failure of the calcium homeostatic mechanisms to maintain serum calcium around the time of calving. Though clinical cases may only arise in ≈ 5% of transition cows, subclinical rates are much higher. Animals suffering from even subclinical milk fever are much more susceptible to numerous other transition disorders. Preventing milk fever by formulation of the prepartum ration may be accomplished by decreasing the dietary cation anion difference (DCAD) which can be defined as the balance between positively and negatively charged ions in the diet. An experiment was designed to test 2 diets containing t products designed to deliver supplementary anions to the diet versus a control ration with no added anions. Total serum calcium and incidence of postpartum health disorders were not affected by prepartum dietary treatment. Though DCAD was drastically different between the control ration and the 2 anionic diets, the concentration of the strong cation potassium was low across all treatments which presumably prevented hypocalcemia with the onset of lactation. Though our diets contained low concentrations of potassium, many diets used by dairymen contain forages that are high in potassium and thus might benefit from the addition of anions. An experiment of an unrelated nature was conducted to observe the effects of 2 diets containing wet corn gluten feed (46 or 56% of DM) as the primary energy substrate and tallgrass prairie hay (14 or 20% of DM) as the sole source of physically effective fiber versus a control ration containing alfalfa and corn silage. The 20% tallgrass prairie hay diet resulted in milk components and efficiencies similar to those of the control ration, but production and income over feed cost did not match that of the control ration in this situation.

Four diets were tested to verify the effect of beef heart as feed enhancer for discus fish, studding the growth, weight gain, survivor, consumption, water quality and economic performance variables. Is was utilized 12 aquariums, distributed in 4 treatments and 3 replications. The treatments were: T1- 100% ration (42%PB); T2- 75% ration and 25% beef heart; T3- 50% ration and 50% beef heart and T4- 25% ration and 75% beef heart. The diets were feed until fish s satiation, twice by day, at 8:00h and 17:00h. After each feed time, 40% of water was changed. Each aquarium contained 20 fishes, totalizing 240 discus fishes. The following water quality parameters were available: pH, dissolved oxygen, temperature and ammonia. There wasn`t effect of treatments on survivor. The dry matter consumption was higher in 50% and 75% of beef heart diets, and better growth and weight gain were obtained, but 50% of beef heart were at a low price, and were considered the best diet. The relative condition factor (Kn) analysis indicate better body condition of fishes according beef heart was higher in tested diets. The economic performance shows that 75% of beef heart obtain lower cost index, but 50% of beef heart obtain higher partial liquid income. However beef heart diets turn water cloudy, the analyzed water quality parameters keep suitable for fishes. The conclusion is that beef heart is efficient as feed enhancer for discus fish and that 50% of beef heart with 50% of ration provide better performance and higher economic gain.
Foram elaborados dois experimentos para obter dados zootécnicos que auxiliem a produção comercial do acará-disco (Symphysodon aequifasciata), com os seguintes objetivos: a) verificar a eficácia da adição de coração de boi como estimulador de consumo, sobre as variáveis de desempenho, sobrevivência, consumo, qualidade de água e desempenho econômico; b) avaliar o efeito da densidade de estocagem sobre o desempenho do acará-disco e obter informações econômicas para determinar qual a melhor densidade para cultivo desta espécie em aquários. No primeiro experimento foram utilizados 12 aquários, com 20 peixes, totalizando 240 acará-disco, divididos em quatro tratamentos e três repetições. Os tratamentos foram: T1- 100% ração (42%PB); T2- 75% ração e 25% coração de boi; T3- 50% ração e 50% coração de boi e T4- 25% ração e 75% coração de boi. As dietas foram fornecidas aos peixes até a saciedade, duas vezes por dia, nos horários de 8:00h e 17:00h. Os tratamentos com 50% e 75% de coração de boi proporcionaram crescimento e ganho de peso significativamente superior, entretanto a dieta com 50% de coração de boi foi mais econômica, sendo considerada a melhor. O segundo experimento recebeu a dieta com 25% ração e 75% coração de boi. As dietas foram fornecidas aos peixes até a saciedade, duas vezes por dia, nos horários de 8:00h e 17:00h. Foram testadas densidades de 8, 12, 16 e 20 peixes/aquário. Os resultados foram submetidos a análises de regressão e a densidade calculada que proporcionaria maior desempenho seria de 17,5 peixes/aquário.

The purpose of this study is to examine the influence and level of parental involvement in the FET phase in Greater Delareyville and to identify the causes of poor parental involvement in learning and teaching. Parents have capabilities and responsibilities of creating vibrant learning areas to promote learners' performance. On the other hand, it is believed that a child, who has not developed any sense of security and competence at home, will fail to explore his/her world and develop a sense of curiosity that is essential for learning and teaching. It is further noted that situational analysis is the best effort to be carried out by parents to ensure that the environment/context in which the children learn is appealing and attractive to fulfill their needs. The problem is while parents should be interested at all costs in the life of their children, watch their moves, guide, advice them regularly, control their work and ensure that they are free to do their work without disturbance, many parents seem not to be interested. This also affects the children and parents of schools in the Greater Delareyville Area. In other instances, teachers blame parents for their lack of interest in their children's education. Data was analysed qualitatively and quantitatively. A computer aided statistical analysis was employed to compute the results of the study. The population for the study was drawn from the secondary schools of the Greater Delareyville APO. Out of the 200 secondary schools in the Greater Delareyville APO. 50 schools were randomly selected for the study. From each of the 50 randomly selected secondary Greater De!areyville APO: a principal, deputy principal, departmental head and an educator were requested to complete the questionnaire. The sample of (N=200) was composed of a total of (4 ) respondents from each of the 50 randomly selected secondary schools in the Greater Delareyvile APO. From the findings of the empirical study and literature review, it is revealed that parental mvolvement in the teaching and learning should be effective. !t !s r.ooed ~1:2: by implementing vaiious decisons made by the committee developed by schools, parents will be more involved in the teaching and learning of their children as they feel that their decisions are seriously considered. The following key words are important in the study as they sum up the writer's ideas in his work. They are thus briefly explained in terms of how they relate to one another in order to reflect a concrete topic of research. Parental involvement is a broad term that includes several forms of participation in education and with the schools in which parents can support their children's schooling by attending school functions and responding to school obligations such as parents- teacher conferences. The primary aim of this involvement is to improve their children's schoolwork, providing encouragement, arranging for appropriate study time and space, modelling desired behaviour, monitoring home-works and actively tutoring their children at home. (Cotton & Wikeland, 2009; 235) Learning is an activity in which the person being taught actively wishes to benefit from the teaching and absorbs particular learning content or by constructing meaningful and structured information in his or her own mind. As acts of teaching and learning are thus polymorphous, indicating that they take many forms (Van Heerden , Van der Merwe, Grobler and Loggerennberg; 2004: 61) Teaching is an act of appropriately displaying some subject matter with the intent that someone learns it. fcl phase refers to Further Education and Training made of various providers such as senior secondary school, technical colleges, National Government Organisations, private training centres, private companies, industry training centres and community colleges, (Policy Document, 1997: 9). However, this study focuses on parental involvement in high schools.

Since the advent of democracy in 1994 South Africa has been faced with the shortage of skilled people and this is caused, amongst other things, by the inadequacy of the outdated National Education Programmes for Technical Colleges (NATED) and later referred to as the N-programmes. To address the problem, the former Department of Education (DoE) developed new programmes called the National Certificate Vocational NC (V) for the students of the Further Education and Training colleges (FETs), which were renamed the Technical Vocational Educational and Training Colleges (TVET). The TVET programmes were implemented with the collaboration of industry and other stakeholders who were involved when the NC (V) programmes were developed to ensure their buy-in. Despite all these efforts, Magnus et al. (2013) are of the view that the vocationally-oriented NC (V) programmes offered at colleges are not useful, work-focused and flexible, as a result some leading employers reject the products of the programmes. Returning to the global debate, Lewis (2009) contends that failure of vocational programmes anywhere ought not to be taken as an indictment of vocationalism. Based on the above scenario, this study surveyed and traced TVET graduates who graduated from 2009 to 2012, to determine the impact of the NC (V) programme on those who decided to either further their studies or be employed. Although the programmes offered by the FET’s are rolled out in various study fields throughout the country, the research was limited to graduates who were enrolled in the following three programmes in the North West Province: building construction, electrical, and engineering related studies. The three mega FET Colleges, composed of more than ten campuses as listed in point 1.2.1, are spread throughout the province, which is regarded to be predominantly rural even though it boasts the biggest hub of mines, especially platinum mines. There is also high concentration of tourism industry as well as agricultural businesses that require a skilled labour force to drive economic activities. An extensive literature review was conducted to appropriately inform the study and to provide a firm basis for the arguments. The NC (V) programmes by their nature and design are closely related to the work of the Sector Education and Training Authorities (SETAs) with respect to the apprenticeships and the learnerships. Factors relating to the research scope, context and the geographical environment were analysed to ensure proper delineation and delimitation of the study since it covered only the North West Province of South Africa. The study used both qualitative and quantitative research methodologies for the collection of data. An interview schedule was used for the collection of the qualitative data from the Colleges, Department of Higher Education and Training, the Sector Education and Training Authorities (SETAs), the Universities of Technologies (UoTs), and the various employer organizations. The questionnaire was applied to collect quantitative data from the graduates because of their large numbers. The use of both methods, the qualitative and quantitative, enhanced the quality of the verification and the validation of the data. The correlational relationship and connection between the NC (V) graduates and their post college destinations was determined. This refers to the correlation between NC (V) graduates and the opportunities seized after their college studies. Charles (1998:11) attests that “although in most cases data for correlation studies are obtained through measurement, at times they come from judgments made by researchers, teachers, or other qualified persons”. In line with this, the researcher presented the findings from the qualitative method in a manner that outlines the opinions and the post college status of the graduates. The findings of the qualitative method provided background knowledge into the NC (V) programmes, the graduates and their destinations, thereby validating the quantitative findings. A work integrated learning framework model is proposed for the enhancement of the FET College curriculum, for the improvement of quality work-placement and for the promotion of partnership amongst the beneficiaries; graduates, employers, colleges and the intermediaries.

L’évaluation de l’action humanitaire (ÉAH) est un outil valorisé pour soutenir l’imputabilité, la transparence et l’efficience de programmes humanitaires contribuant à diminuer les inéquités et à promouvoir la santé mondiale. L’EAH est incontournable pour les parties prenantes de programme, les bailleurs de fonds, décideurs et intervenants souhaitant intégrer les données probantes aux pratiques et à la prise de décisions. Cependant, l’utilisation de l’évaluation (UÉ) reste incertaine, l’ÉAH étant fréquemment menée, mais inutilisé. Aussi, les conditions influençant l’UÉ varient selon les contextes et leur présence et applicabilité au sein d’organisations non-gouvernementales (ONG) humanitaires restent peu documentées. Les évaluateurs, parties prenantes et décideurs en contexte humanitaire souhaitant assurer l’UÉ pérenne détiennent peu de repères puisque rares sont les études examinant l’UÉ et ses conditions à long terme. La présente thèse tend à clarifier ces enjeux en documentant sur une période de deux ans l’UÉ et les conditions qui la détermine, au sein d’une stratégie d’évaluation intégrée au programme d’exemption de paiement des soins de santé d’une ONG humanitaire. L’objectif de ce programme est de faciliter l’accès à la santé aux mères, aux enfants de moins de cinq ans et aux indigents de districts sanitaires au Niger et au Burkina Faso, régions du Sahel où des crises alimentaires et économiques ont engendré des taux élevés de malnutrition, de morbidité et de mortalité. Une première évaluation du programme d’exemption au Niger a mené au développement de la stratégie d’évaluation intégrée à ce même programme au Burkina Faso. La thèse se compose de trois articles. Le premier présente une étude d’évaluabilité, étape préliminaire à la thèse et permettant de juger de sa faisabilité. Les résultats démontrent une logique cohérente et plausible de la stratégie d’évaluation, l’accessibilité de données et l’utilité d’étudier l’UÉ par l’ONG. Le second article documente l’UÉ des parties prenantes de la stratégie et comment celle-ci servit le programme d’exemption. L’utilisation des résultats fut instrumentale, conceptuelle et persuasive, alors que l’utilisation des processus ne fut qu’instrumentale et conceptuelle. Le troisième article documente les conditions qui, selon les parties prenantes, ont progressivement influencé l’UÉ. L’attitude des utilisateurs, les relations et communications interpersonnelles et l’habileté des évaluateurs à mener et à partager les connaissances adaptées aux besoins des utilisateurs furent les conditions clés liées à l’UÉ. La thèse contribue à l’avancement des connaissances sur l’UÉ en milieu humanitaire et apporte des recommandations aux parties prenantes de l’ONG.
Evaluation of humanitarian action (EHA) is increasingly deployed as a means to enhance accountability, transparency, and efficiency of humanitarian programs aimed at reducing health inequities and promoting global health. EHA has become a vital tool for program stakeholders, funding agencies, and policy-makers seeking to render practice and decision-making more evidence-based. However, considerable uncertainty remains about evaluation use (EU), as EHA is frequently conducted without being used. Moreover, conditions that influence EU vary across contexts and their applicability in humanitarian non-governmental organizations (NGOs) remains unclear. Program evaluators, stakeholders, and policy-makers in humanitarian contexts have little guidance to support long-term EU, given that few studies have documented EU and its conditions over time. The aim of the present qualitative thesis is to shed light on these issues by documenting EU and the conditions influencing it over a 29-month period within an evaluation strategy embedded into a humanitarian NGO’s health care user fee exemption program. To facilitate access to care, the exemption program subsidized the health service fees of mothers, children under five, and indigents in health districts of Niger and Burkina Faso—West African Sahel regions where food crises and poverty have engendered high rates of malnutrition, morbidity, and mortality. Initial evaluation of the exemption program in Niger led to development of the evaluation strategy subsequently integrated into the same program developed in 2008 in Burkina Faso. The thesis consists of three articles. The first presents an evaluability assessment (EA), a preliminary step undertaken to determine whether an EU evaluation was feasible. Results showed the evaluation strategy’s logic was coherent and plausible, data was accessible, and evaluation strategy stakeholders deemed an EU study to be useful. The second article documents how stakeholders engaged in EU and how it served them and advanced the NGO’s mission. Results showed that stakeholders used findings instrumentally, conceptually, and persuasively, but used evaluation processes only instrumentally and conceptually. The third article identifies the conditions stakeholders saw as influencing EU over time. Key influential conditions were users’ attitudes toward evaluation, stakeholders’ interactions and communications, and evaluators’ skill in producing and sharing evaluation-based knowledge tailored to users’ needs. This thesis furthers knowledge on EU in the humanitarian action context and provides practical recommendations for stakeholders of NGOs.

The focus of this thesis is on Advance Fee Fraud (419 scams) on how it is executed and more importantly, on how it can be prevented. The research addresses the origins of AFF, the nature and extent of this crime and how the perpetrators are able to defraud their victims. The research described, examined and analysed the crimes, the perpetrators, the victims, adjudication and the prevention strategies of this fraud. Information was gathered through literature and empirical research. A qualitative research method was used to gather information from AFF offenders who were incarcerated in South African prisons in 2005. The results of the empirical research were carefully examined, analyzed and integrated into the various chapters of this thesis. A theoretical framework was also developed in an attempt to explain this complex phenomenon. The findings and recommendations in terms of the crimes, the criminals, the victims, adjudication and prevention were also made and some suggestions for further research thereof were also cited.

Based on ongoing research, the poultry industry is utilizing increasingly more wheat distillers dried grains with solubles (wDDGS) as a feed ingredient. High fiber in wDDGS is a major factor contributing to reduced nutrient intake and digestion of nutrients in the diet. Hence, the research conducted looks at emerging technologies (e.g., enzymes and/or feed processes (extrusion) and/or wet feeding) to overcome the limitations in diets containing higher levels of WDDGS. The dietary treatments were evaluated by monitoring turkey performance and utilization of the nutrients. All dietary treatments in the respective experiments were formulated to meet or exceed the nutrient requirement of the Hybrid Converter turkey standards. With the exception of experiment 2 (0-72d) test diets were fed from 7-21d. In Experiment 1, 0 and 30% wDDGS diets were supplemented with protease (P+; 0.126 g/kg) or β-mannanase (M+; 0.05g/kg); further, diets containing 0, 10, 20 and 30% wDDGS with no enzyme were compared. A positive (P<0.05) main effect of 30% was reported for 21d body weight (BW) and feed conversion ratio (FCR). A significant main effect [21d apparent metabolizable energy (AME); 30%] and interactions [(enzymes x levels (0 and 30%); 21d AME and nitrogen retention (NR)] were found. A quadratic (P<0.01) response was found for FCR, that was superior for 30%. A quadratic (P<0.01) response was also found for both NR and AME; both were highest for 10% wDDGS diets. In Experiment 2, diets containing 0, 15 and 30% wDDGS with no enzyme were compared; further, the 30% wDDGS diet was supplemented with enzymes (protease or β-mannanase). Water intake per pen was monitored beginning at 7 d. There was no effect of dietary treatment on overall feed intake (FI) and body weight (BW). Total feed conversion ratio (FCR) (P<0.05; 0-72d) was significantly improved for birds fed 30% wDDGS regardless of enzyme treatment compared other dietary treatments. There were trends for higher water intake (mL/b/d) with 30%P+ diets as compared to the other diets. The higher water intake may be a factor of the higher fiber in this diet, but it was exacerbated by only the protease enzyme. Experiment 3 evaluated the effect of extrusion (EX) and an enzyme cocktail (E; 0.5g/kg) on wDDGS. Diets containing 0, 15 and 30% wDDGS with/without enzyme were tested; further, the 15 and 30% wDDGS with/without EX and E were compared. There was no effect of EX or E on BW and FI. Feeding higher WDDGS (30%) depressed performance, but an improved NR and AME was recorded. In Experiment 4, a small study was conducted to evaluate if wet feeding (WF; 1.2 mL water: 1.0 g feed) of diets with 30% wDDGS would impact turkey poult performance. The WF significantly improved BW, FI and FCR. It is apparent from these studies that high levels of WDDGS were not detrimental to overall performance. The high levels of wDDGS with no loss of production would result in a higher demand of wDDGS for use in turkey diets. Overall, we saw no improvements in performance with individual supplementation of protease, β-mannanase or an enzyme cocktail. Neither was extrusion of wDDGS beneficial. Voluntary feed consumption is improved when diets are wetted before feeding.

Napiergrass (Pennisetum purpureum) is regarded as a potential energy crop and can be used for the production of fuels and chemicals. In addition, Napiergrass juice prevails recently in Taiwan as a functional juice due to its beneficial health effects. However, the fibrous residues after juice extraction have not yet found suitable uses. In order to fully utilize the Napiergrass biomass, we investigated the clean fractionation of Napiergrass using the wet-oxidative steam explosion technology. In this study, the wet-oxidative steam explosion was performed in two stages under a constant temperature of 190℃. The effects of residence time and oxygen content on xylooligosaccharide production and residual solid composition were investigated using a factorial experimental design. The residence time ranged from 5 to 25 min and the oxygen content from 0 to 60%. The steam explosion conditions were optimized for the production of xylooligosaccharides. The residual solids after steam explosion were subjected to a further alkaline delignification step before their digestibility was determined using the pepsin-cellulase method. The alkaline delignification was carried out with a 5% (w/w) sodium hydroxide solution at 80℃for 30 min. Napiergrass were subjected to wet oxidative (WO) steam explosion, followed by an alkaline treatment. By two stages wet oxidative (WO) steam explosion. The total yield of Xylo-oligosaccharides and solubility xylan yield up to 52.7%. The digestibility from 22.9% up to 62.4%. The effects of WO steam explosion residence time and oxygen content on Xylo-oligosaccharides and lignin removal and digestibility were studied using experimental design. When Xylo-oligosaccharides are considered as a product, a milder WO steam explosion condition should be used.

In the summer of 2007, a single neighbourhood in downtown Toronto contributed at least 13 percent of all residential grid???tie solar photovoltaic (PV) systems sold in the Canadian province of Ontario. On average, PV purchaser households produced 37 percent as much electricity as they consumed. This research investigates solar energy adoption in a community case study. Specifically, it investigates why some residents who sign up for a solar resource assessment through a community solar energy initiative (CSEI) decide to purchase, and others decide not to purchase in the short???term. Characteristics and perceptions of potential adopters are analyzed to better understand their motivations and barriers to adoption. Community energy projects became an official public policy goal in Ontario, with the passing of the Green Energy and Green Economy Act in 2009. Approximately 80 percent of Ontario???s anticipated generation capacity will need to be built, replaced or refurbished within 15 years. In this context, the Ontario Ministry of Energy, Ontario Power Authority, and Deloitte (one of Canada???s leading professional services firms), have partnered with a ???green benefit??? fund, the Community Power Fund, to help local community groups access resources to develop and establish renewable energy projects. Understanding solar energy adoption in a community context is therefore important to improve the effectiveness of such policies, including the disbursement of multi???million dollar grant funds. Differences between purchasers and non???purchasers in respect of adoption behaviour were found in this study to cluster around two general themes. The first theme concerns differences in compatibility of both the concept of solar energy systems, and their physical attributes, with characteristics of potential adopter households. Some compatibility issues are straightforward, e.g. availability of roof space with a southern orientation. Others are more complex, involving several interrelated perceptual and socio???demographic factors. For instance, while both purchasers and non???purchasers rated cost as a very important barrier, purchasers rated the motivation of solar energy systems to reduce climate change higher relative to the barrier of high financial costs than did non???purchasers. Purchasers were also more likely to possess a graduate degree, while non???purchasers were more likely to hold a professional degree. The second general theme relates to potential adopters??? trust and stake in the ability of the community???based initiative to reduce barriers in the adoption process. Since two types of solar energy systems are considered in the case study???PV and thermal (hot water)???differences are explored between each of three respondent groups: solar PV purchasers, solar hot water (SHW) purchasers, and non???purchasers. iv Surveys were used to gather data on adopter perceptions and characteristics. A participatory research design helped identify the research topic. Two main bodies of literature???community???based social marketing (CBSM) and diffusion of innovations theory???were drawn upon to conceptualize the adoption process and interpret the survey findings. These include five models of human behaviour that can be used to guide the design of CBSM campaigns. Diffusion theory was used as a basis for discussing ???perceived innovation attributes???. The study takes an integrated approach by considering both social and technical aspects of solar energy adoption, together with the issues of fuel substitution and household electricity demand.

Problématique : Dans les pays africains où les soins de santé sont encore payants au point de service, la barrière financière est un des obstacles majeurs au recours aux soins. Les indigents, qui sont les plus démunis, en sont les plus affectés. Pour faire face à ce défi, certains pays ont entrepris l’élaboration de programmes de santé ciblant les indigents pour leur permettre d’avoir un meilleur recours aux soins de santé par l’intermédiaire d’une exemption du paiement. Mais il existe un réel défi à identifier les indigents. De plus, peu d’études ont évalué l’impact de programmes d’exemption du paiement sur leur recours aux soins. Les indigents sont en majorité des personnes âgées avec des besoins importants en santé. Les personnes âgées en Afrique consultent très peu les professionnels de santé et les déterminants de leur recours aux soins sont peu connus. Pourtant, leur proportion est en augmentation dans les pays à faibles et moyens revenus. Ils sont en perte d’autonomie, ont de faibles revenus et présentent une prévalence élevée de maladies chroniques et d’incapacités fonctionnelles. Ces affections surviennent de façon précoce surtout chez les femmes. Objectifs : Cette thèse a pour objectifs : i) de déterminer le caractère équitable d’un processus de sélection communautaire des indigents au Burkina Faso qui vise à les faire bénéficier d’une exemption du paiement des soins; ii) de mesurer l’impact de ce programme d’exemption sur le recours aux soins de santé des indigents ; iii) d’analyser les facteurs associés au recours aux soins de santé par les personnes âgées au Nigéria. Méthode : Le cadre conceptuel de cette étude est le modèle d’Andersen et Newman qui regroupe les déterminants de l’utilisation des soins de santé en facteurs prédisposants (âge, sexe, état matrimonial, occupation), en facteurs facilitants (revenu, existence d’un recours à une aide financière, alimentaire ou instrumentale, cohabitation) et en besoins (présence de maladies chroniques et de limites de la vision, de la force musculaire et de la mobilité). Dans un premier temps, pour déterminer le caractère équitable d’une sélection communautaire des indigents, nous avons réalisé une étude transversale en 2010 dans le district de Ouargaye au Burkina Faso. Au cours de cette enquête, 1687 indigents ont été interrogés. La variable dépendante est la possession de la carte d’exemption du paiement des soins. Des analyses bivariées et une régression logistique ont été réalisées. Dans un deuxième temps, à partir d’un devis quasi expérimental pré/post, nous avons évalué les effets de ce programme d’exemption du paiement des soins sur le recours aux soins de santé des personnes en situation d’indigence au Burkina Faso. Au cours de cette recherche, 1224 indigents ont été interrogés en 2010 sur leur recours aux soins de santé. Parmi eux, 540 ont été sélectionnés et ont reçu une carte d’exemption du paiement des soins. Un an plus tard, un suivi a été réalisé avec un taux de rétention de 55,3%. Des analyses bivariées et une régression logistique ont été réalisées. Dans un troisième temps, à partir des données d’une étude transversale nationale, le General Household Survey de 2012-2013 du Nigéria qui couvre toutes les régions du pays, nous avons étudié le recours aux soins de 3587 personnes âgées dont 850 ont déclaré avoir été malades. Nous avons tenté d’identifier les facteurs qui y sont associés. Des analyses pondérées bivariées et une regression de Poisson pondérée ont été effectuées. Résultats : Au Burkina Faso, l’exemption du paiement des soins a été accordée en majorité aux veufs (ves) (OR=1,40 IC 95% [1,10-1,78]), à ceux qui ne bénéficient pas d’aide financière de leur ménage pour recourir aux soins de santé (OR=1,58 IC 95% [1,26-1,97], qui vivent seuls (OR=1,28 IC 95% [1,01-1,63]), qui vivent avec leurs époux/se (OR=2,00 IC 95% [1,35-2,96], qui ont des troubles de la vision (OR=1,45 IC 95% [1,14-1,84]), qui ont une faible force musculaire et une bonne mobilité (OR=1,73 IC 95% [1,28-2,33]). Le processus de sélection communautaire des indigents n’est pas parfaitement équitable, car très restrictif, bien qu’il ait permis de sélectionner les plus démunis. Il existe des différences de genre concernant les déterminants du recours aux soins chez les indigents. Être veufs (OR=0,53 IC 95% [0,33-0,81]) et avoir des troubles de la vision (OR=0,42 IC 95% [0,28-0,63]) freinent le recours aux soins chez les hommes, mais pas chez les femmes. Les maladies chroniques demeurent un obstacle commun aux hommes (OR=4,05 IC 95% [2,84-5,77]) et aux femmes (OR=2,14 IC 95% [1,54 – 2,97]). Le fait d’être exempté du paiement des soins n’est pas associé à l’augmentation de l’utilisation des services de santé (OR=1,1 IC 95% [0,80-1,51]). Qu’ils aient bénéficié ou pas de l’exemption du paiement des soins, les indigents qui ont un âge supérieur à 69 ans (OR=1,66 IC 95% [1,05-2,64]), qui appartiennent au genre masculin (OR=1,44 IC 95% [0,99-2,08]), qui appartiennent à un ménage à faible revenu (OR=1,71 IC 95% [1,15-2,54]) et ceux qui ont recours à l’aide financière familiale pour accéder aux soins de santé (OR=1,59 IC 95% [1,1-2,28]), sont les plus susceptibles d’augmenter leur utilisation des soins de santé. Au Nigéria, seulement 53% des personnes âgées ont consulté un agent de santé suite à un épisode de maladie. L’absence de scolarisation (PR = 0.73, 95% CI [0.6 0–0.8]), la faiblesse du revenu de ménage (PR = 0.75, 95% CI [0.5–0.9]), et le fait de résider dans les zones du Sud-Sud (PR = 0.59 95% CI [0.4–0.7]) et du Sud-Ouest (PR = 0.60 95% CI [0.4–0.7]), constituent des freins à la consultation d’un agent de santé. Conclusion La sélection communautaire est une des méthodes qui semble avoir permis de sélectionner les indigents avec une prévalence élevée de besoins en santé et d’obstacles économiques au recours aux soins. Cependant, l’exemption du paiement des soins n’est pas suffisante pour améliorer leur recours aux soins. Les déterminants de leur recours aux soins différent selon le genre, mais les maladies chroniques constituent un motif commun. Les personnes âgées et les indigents ont des caractéristiques communes telles que l’âge avancé, mais certains facteurs qui déterminent leurs recours aux soins diffèrent. Le déterminant commun est le facteur financier, soit la capacité contributive de ces personnes dans un contexte où l’utilisateur des services de santé est le payeur. En attendant la couverture universelle de soins, il serait approprié que les interventions pour améliorer le recours aux soins ciblent en premier lieu les populations ayant des besoins importants telles que les indigents et les personnes âgées en ôtant la barrière financière. Pour les indigents par contre, il faudrait y ajouter des mesures additionnelles comme, par exemple l’accompagnement, le transport et les frais d’hébergement. Enfin, les interventions doivent aussi considérer les différences de genre qui existent dans les facteurs qui déterminent leur recours aux soins.
Problem In African countries with point-of-service healthcare user fees, financial barriers are one of the major obstacles to healthcare-seeking behaviour, and the indigent, the poorest members of society, are the most affected. To address this issue, some countries have begun developing health programs targeting indigent people to help them gain better access to healthcare by waiving healthcare fees. Unfortunately, it is a genuine challenge to identify those who are indigent. In addition, few studies have assessed the impact of user fees exemption programs on healthcare-seeking behaviour. The majority of indigent people are older with significant health needs. Older people in Africa do not often consult health professionals. The determinants regarding healthcare-seeking behaviour by older people is little-known, although proportionately, their numbers are increasing in low- and middle- income countries. They are losing their autonomy, have little income and have a high prevalence of chronic diseases and functional disabilities. These problems occur early on, especially among women. Objectives The objectives of this thesis are as follows: (i) to determine the equitable nature of a community-based selection process for indigent people in Burkina Faso that aims to exempt them from paying healthcare user fees; (ii) to measure the impact of this user fees exemption program on healthcare-seeking behaviour among indigent people; (iii) to analyze the factors associated with healthcare-seeking behaviour by older people in Nigeria. Method The conceptual framework of this study is based on the model developed by Andersen and Newman, which groups healthcare use determinants into predisposing factors (age, gender, marital status, occupation), enabling factors (income, means and know-how to access financial, food or instrumental assistance, social relationships), and needs (presence of chronic disease and vision, muscle strength and mobility limitations). To determine the equitable nature of a community-based selection of indigent people, we carried out a cross-sectional study in 2010 in the Ouargaye District of Burkina Faso, in which 1687 indigent people were interviewed. The dependent variable was possession of an exemption card. Bivariate analyses and logistic regression were performed. Next, using a quasi-experimental before/after approach, we assessed the effects of this user fees exemption program on healthcare-seeking behaviour by indigent people in Burkina Faso. To that end, 1224 indigent people were interviewed in 2010 about their healthcare-seeking behaviour. Among them, 540 were selected and received an exemption card. One year later, a follow-up was conducted, with a 55.3% retention rate. Bivariate analyses and logistic regression were performed. Finally, using data from a national cross-sectional study, the Nigerian 2012–2013 General Household Survey, which covers all the country’s regions, we studied healthcare-seeking behaviour by 3587 older people, of whom 850 stated that they were ill. We attempted to identify the associated factors. Weighted bivariate analyses and a weighted Poisson regression were performed. Results In Burkina Faso, healthcare payment waivers were mainly granted to widows or widowers (OR=1.40 IC 95% [1.10–1.78]), to those who do not receive financial support from their household for healthcare (OR=1.58 IC 95% [1.26–1.97], or those who live alone (OR=1.28 IC 95% [1.01–1.63]), or with their spouse (OR=2.00 IC 95% [1.35-2.96], who have vision impairment (OR=1.45 IC 95% [1.14–1.84]), who have limited muscle strength and good mobility (OR=1.73 IC 95% [1.28–2.33]). The community-based selection process of indigent people is not completely equitable, although it did enable the most needy to be selected. There are gender differences concerning healthcare-seeking behaviour determinants among indigent people. Being a widower (OR=0.53 IC 95% [0.33–0.81]), and having vision impairment (OR=0.42 IC 95% [0.28–0.63]) were factors limiting healthcare-seeking behaviour among men but not among women. Chronic diseases remain a common obstacle among men (OR=4.05 IC 95% [2.84–5.77]) and women (OR=2.14 IC 95% [1.54–2.97]). User fees exemption is not associated with an increased use of healthcare services (OR=1.1 IC 95% [0.80–1.51]). Whether they received or did not receive exemption cards, indigent people over the age of 69 (OR=1.66 IC 95% [1.05–2.64]), who were male (OR=1.44 IC 95% [0.99–2.08]), who belong to a low-income household (OR=1.71 IC 95% [1.15–2.54]), and those who had financial assistance from family to access healthcare (OR=1.59 IC 95% [1.1–2.28]), are more likely to increase their use of healthcare. In Nigeria, only 53% of older people consulted a health practitioner after an episode of illness. Lack of education (PR = 0.73, 95% CI [0.60–0.8]), low household income (PR = 0.75, 95% CI [0.5–0.9]), and residence in Nigeria’s South South (PR = 0.59 95% CI [0.4–0.7]) and South West zones (PR = 0.60 95% CI [0.4–0.7]) constituted limitations to consulting a health practitioner. Conclusion Community-based selection is one method that appears to have made it possible to select indigent people with a high prevalence of health needs and obstacles to seeking healthcare. Healthcare payment waivers are not sufficient to increase their healthcare-seeking behaviour. Healthcare use determinants differ according to gender, but chronic disease constitutes a common theme. Elderly and indigent people have common characteristics, such as advanced age, but some factors that determine their healthcare-seeking behaviour differ. The common determinant is the financial factor, i.e., the contributory capacity of these people in a context where the user pays. Until there is universal healthcare coverage, it would be appropriate to ensure that activities to improve healthcare-seeking behaviour primarily target populations with significant needs, such as indigent and elderly people, by removing financial barriers. For indigent people, however, additional measures must be included, such as accompaniment, transportation and accommodation expenses. And activities must also take existing gender differences into account among the factors determining their healthcare-seeking behaviour.

HOLCIM has various cement production plants across India. These plants struggle to produce the projected amount of cement due to electricity shortages. Although coal is abundant in India, the production thereof is in short supply. It is proposed that a thorium HTR (100 MWt) combined with a PCU (Rankine cycle) be constructed to supply a cement production plant with the required energy. The Portland cement production process is investigated and it is found that process heat integration is not feasible. The problem is that for the feasibility of this IPP to be assessed, a Rankine cycle needs to be adapted and optimised to suit the limitations and requirements of a 100 MWt thorium HTR. Advantages of the small thorium HTR (100 MWt) include: on-site construction; a naturally safe design and low energy production costs. The reactor delivers high temperature helium (750°C) at a mass flow of 38.55 kg/s. Helium re-en ters the reactor core at 250°C. Since the location of the cement production plant is unknown, both wet and dry cooling tower options are investigated. An overall average ambient temperature of India is used as input for the cooling tower calculations. EES software is used to construct a simulation model with the capability of optimising the Rankine cycle for maximum efficiency while accommodating various out of the norm input parameters. Various limitations are enforced by the simulation model. Various cycle configurations are optimised (EES) and weighed against each other. The accuracy of the EES simulation model is verified using FlowNex while the optimised cycle results are verified using Excel’s X-Steam macro. It is recommended that a wet cooling tower is implemented if possible. The 85% effective heat exchanger delivers the techno-economically optimum Rankine cycle configuration. For this combination of cooling tower and heat exchanger, it is recommended that the cycle configuration consists of one de-aerator and two closed feed heaters (one specified). After the Rankine cycle (PCU) has been designed and optimised, it is evident that the small thorium HTR (100 MWt) can supply the HOLCIM plant with the required energy. The optimum cycle configuration, as recommended, operates with a cycle efficiency of 42.4% while producing 39.867 MWe. A minimum of 10 MWe can be sold to the Indian distribution network at all times, thus generating revenue.
