The principal objective of this thesis is the comprehension of students' mental processes while solving verbal math problems about money. There searchis focused on pupils in the first stage of primary school and in particular verbal math problems, in which nominal value of coins, quantity of coins and their total particular verbal math problems, in which nominal value of coins, quantity of coins and their total sum play a key role. There fore, the objective of this diploma thesis is to lay out classify mony-related exprecises in thee currently used lies of elementary school mathematics text books for grade. The theoretical part consist of demarcation of early school age, a certain number of fanticipate dacts by RVP ZV for the first and second educational period, numeracy, literacy, verbal math problems, various strategies on how to solve such problems, basic is sues pipils encounter whilw solving those problems, coments on the topic of verbal math problems which appear in theree volume soft text books in tended for primary schools (Prodos, Taktic, H-mat). Their division into three types (a total sum of coins, nominal value of coins and number of coins) and their mutual comparision. The goal of the practial part is to analyse thought processes of and grade pupils when solving word problems about...

It has been determined who the adolescent in the Wolmer community is. An investigation into the adolescent’s relationship with the resources in this area was also done. It was determined that this community has a long history of poverty and that a large percentage of the families living here experience a variety of problems. We refer to them as multi-problem families. It has also been confirmed that social services by various organizations have been delivered on an ongoing base over the past eight years. From the literature we have learned that the use of resource’s aid programmes as means of social support, focusing on families, primary and secondary school learners, should have an impact on the future expectations of the children involved. The aim of this study was to determine what the perception of the grade seven learners of their future expectations was. From this it would then be possible to derive what recommendations should be made with regard to social work programmes for the parents and children in the Wolmer community. Socio-economic problems that are not addressed cause bad school performance and as a result of this children tend to leave school at an early age. Leaving school at an early age evidently leads to conflict with the police, imprisonment and alcohol and drug abuse. These aspects tend to be a part of the life in Wolmer and ultimately have an influence on the child attaining his or her goals as well as on his or her future expectations. These will have to be addressed by appropriate school programmes. The researcher’s knowledge of this community leads her to the conclusion that the absence of parenting by the parents of these children, their lack of involvement, lack of skill to equip their children adequately for life, their own lack of adequate knowledge as well as lack of a proper value system tends to play a huge part in the behaviour and perception of the adolescent of their own future expectation. In the Wolmer community children that are sometimes advised by their parents not to leave school at an early age, question this because of parents leaving school at an early age in order to co-provide for their families. In cases where children do not have the cognitive ability to change their surroundings, they tend to too fall back in the vicious circle known to them and the generations before them. The child must be motivated and idealistic and be able to make realistic decisions. Because of this it is of the utmost importance that children that do not have the ability with regard to the abovementioned are assisted in doing so. Also that aid programs in future be focused on this in order to empower the new generation. Parents have a huge influence on the choices made by their children. Regardless of social standing and ability adolescents usually have higher ideals for themselves when their parents motivate them as well as give recognition to good work. The researcher unfortunately came to realize that the assistance by their parents, are a very rare phenomenon in this community. Out of the two focus groups being held with the adolescents, it seemed a lack of interest by the parents, lack of information on higher education as well as little financial resources, have a huge impact and influence on the future expectation of the adolescent in Wolmer. It would be the ideal situation if adolescents chose a career that suited their abilities, interests and personality and that would promote a higher self-esteem. Because of their circumstances this is not always possible for the adolescents in this community. These happen in vary rare cases because the parent’s expectations for their children usually fit their expectations for themselves, which is usually very low. Peer group pressure and peer group acceptance have a huge impact on taking responsibility and on the making of choices. In order to have future success individuals can use their problem-solving abilities, mobilise their social support system and become involved in skills that will promote their social capability. The above mentioned should be actively addressed by social workers in the development of programs that focuses on social support, problem-solving skills, peer group acceptance, school involvement and socio-economic adaptation off adolescents in die Wolmer community. By determining the future expectations of the youth, programs for the empowerment of them can be implemented in order to assist the adolescents to break away from the vicious circle of poverty and to reach their ideals. The researcher is of the opinion that is has become of the utmost importance for the resources in this community, to assess their role presently in the promoting of future expectations and as an outcome of this the promotion of economic-self sustainability. / Dissertation (MSW) (Play Therapy))--University of Pretoria, 2004. / Social Work and Criminology / Unrestricted

Unmanned Aerial Vehicle (UAV), also called drones, are used for Search And Rescue (SAR) missions, mainly in the form of a pilot manoeuvring a single drone. However, the increase in labour to cover larger areas quickly would result in a very high cost and time spent per rescue operation. Therefore, there is a need for an easy to use, low-cost, and highly autonomous swarm of drones for SAR missions where the detection and rescue times are kept to a minimum. In this thesis, a Subsumption-based architecture is proposed, which combines multiple behaviours to create more complex behaviours. An investigation of (1) what are the critical aspects of controlling a swarm of drones, (2) how can a combination of different behavioural algorithms increase the performance of a swarm of drones, and (3) what benchmarks are necessary when evaluating the fitness of the behavioural algorithms. The proposed architecture was simulated in AirSim using the SimpleFlight flight controller through experiments that evaluated the individual layers and missions that simulated real-life scenarios. The results validate the modularity and reliability of the architecture, where the architecture has the potential for improvements in future iterations. For the search area of 400×400meters, the swarm consistently produced an average area coverage of at least 99.917% and found all the missing people in all missions, with the slowest average being 563 seconds. Compared to related work, the result produced similar or better times when scaled to the same proportions and higher area coverage. As comparisons of results in SAR missions can be difficult, the introduction of Active time can serve as a benchmark for others in future swarm performance measurements.

La maladie d'Alzheimer (MA) – la forme la plus courante de trouble neurocognitif majeur – se caractérise typiquement par des troubles progressifs et insidieux de la mémoire épisodique. Des déficits langagiers font également partie du portrait clinique de la maladie, et sont déjà présents au stade préclinique du trouble neurocognitif léger (TNCL). Des difficultés sur le plan de la production du langage ont été rapportées dans la MA et même le TNCL, ce qui suggère que son évaluation pourrait représenter une opportunité unique de détection précoce du déclin cognitif. Un consensus croissant propose d’ailleurs que le langage spontané (LS) pourrait permettre une évaluation écologiquement valide des capacités de production langagière. Toutefois, les résultats d’études s’étant penchées sur l’évaluation du LS ne convergent pas tous pour dresser un portrait clair de l’impact du déclin cognitif sur la production langagière dans la MA, et moindrement encore dans le TNCL. La première partie de la thèse visait ainsi à décrire de façon exhaustive l’étendue de la recherche dans le domaine de l'évaluation du LS dans les populations MA et TNCL, en réalisant un examen de la portée (étude 1). Les résultats ont révélé que l’évaluation traditionnelle du LS consistait le plus souvent en une analyse quantitative d’une sélection de variables microlinguistiques de LS obtenu à l’aide d’une mesure descriptive standardisée. Ayant répliqué le patron des déficits langagiers largement répandu dans les écrits scientifiques, les résultats de l’examen de la portée soulignent l’apport complémentaire de l’évaluation du LS à l’évaluation globale du langage dans les populations MA et TNCL. Toutefois, l’examen de la portée a également souligné d’importantes lacunes dans le domaine de recherche, notamment le très peu d’études s’étant intéressées au TNCL comparativement à la MA, ainsi que le très peu d’approches écologiques à l’évaluation du LS. Prenant en compte ces lacunes, la deuxième partie de la thèse visait à examiner l’apport d’une évaluation écologique du LS auprès de participants TNCL et de contrôles, dans un contexte expérimental se rapprochant de la vraie vie (étude 2). Plus précisément, une évaluation fonctionnelle des actes de langage produits par ces deux groupes lors de la réalisation, dans un appartement-test, de tâches écologiques inspirées d'activités de la vie quotidienne a été réalisée. La description qualitative des actes de langage spontanément produits pendant la planification et l'exécution de ces tâches complexes a permis d'extraire des stratégies, des barrières et des réactions distinctes en réponse aux demandes des tâches ainsi qu'aux difficultés rencontrées chez les participants TNCL et contrôles. Ainsi, les résultats ont montré que les participants TNCL mettaient en place moins de stratégies proactives avant d’entamer l’expérimentation, puis davantage de stratégies compensatoires pour supporter leur organisation des tâches pendant leur exécution. Plus distraits et moins portés à tenir compte de l’assistance offerte, ils validaient et justifiaient davantage leur performance de façon défensive et étaient plus réactifs à leurs difficultés que les sujets contrôles. Les résultats de la deuxième étude de la thèse soulignent ainsi l’apport novateur d’une évaluation fonctionnelle du LS comme outil d'exploration de l'impact du déclin cognitif lors de tâches écologiques complexes se rapprochant d'activités de la vie quotidienne. Ensemble, les études de la thèse convergent pour appuyer l’apport complémentaire d'une évaluation fonctionnelle du LS à son évaluation traditionnelle dans l’avancement des connaissances au sujet de l’impact du déclin cognitif dans les populations TNCL et MA sur la production langagière. / Alzheimer's disease (AD) – the most common form of major neurocognitive disorder – is typically characterized by progressive and insidious impairment of episodic memory. Language deficits are also part of the clinical picture of the disease, and are already present in the preclinical stage of mild neurocognitive disorder (mild NCD). Difficulties in language production have been reported in AD and even in mild NCD, suggesting that its assessment may represent a unique opportunity for early detection of cognitive decline. There is a growing consensus that connected speech (CS) may provide an ecologically valid assessment of language production abilities. However, the results of studies that have examined CS assessment do not all converge to provide a clear picture of the impact of cognitive decline on language production in AD, and even less so in mild NCD. The first part of the thesis thus aimed to comprehensively describe the extent of research in the area of CS assessment in AD and mild NCD populations, by conducting a scoping review (study 1). The results revealed that traditional CS assessment most often consisted of quantitative analysis of a selection of microlinguistic variables of CS, obtained using a standardized descriptive measure. Having replicated the pattern of language deficits widely found in the scientific literature, the results of the scoping review highlight the complementary contribution of CS assessment to the overall assessment of language in AD and mild NCD populations. However, the scoping review also highlighted important gaps in the research field, including the very few studies that have focused on mild NCD in comparison to AD, as well as the very few ecological approaches to CS assessment. Taking these gaps into account, the second part of the thesis thus aimed to examine the contribution of a functional assessment of CS that is closer to the context of real life, with mild NCD participants and controls (study #2). More precisely, a functional assessment of the speech acts produced by these two groups during the performance of ecological tasks inspired by activities of daily living in a laboratory-apartment was carried out. Qualitative description of the speech acts spontaneously produced by these participants while performing complex tasks allowed for the extraction of distinct strategies, barriers and reactions in response to task demands as well as to the difficulties encountered by the mild NCD participants and controls. Thus, results showed that mild NCD participants implemented fewer proactive strategies before beginning the experiment, and then more compensatory strategies to support their task organization during task execution. More distracted and less likely to take into account the assistance offered, they validated and justified their performance more defensively and were more reactive to their difficulties than the control subjects. The results of the second article of the thesis thus highlight the innovative contribution of a functional assessment of CS as a tool for exploring the impact of cognitive decline in complex, ecological tasks that are similar to activities of daily living. Together, the studies in this thesis converge to support the complementary contribution of a functional assessment of CS to its traditional assessment in advancing knowledge about the impact of cognitive decline on language production in the mild NCD and AD populations.

The memory and spatial navigation are extremely important brain functions for humans, but they are often the question of life and death for animals. In humans, memory can be disrupted by various neuropsychiatric disorders. The patients suffering from Alzheimer's dementia (AD) have impaired working and long-term memory, spatial navigation, higher cognitive functions and social memory. The deficit of cognitive coordination (the skill to recognize the relevancy of incoming information) and disorientation belong to the symptomatology of schizophrenia. Intelectual disability appears in some patients with autism spectrum disorder. Unfortunately, it is not possible to cure these disorders efficiently because the etiology is not known in the majority of patients. The causes leading to development of these disorders could be revealed using animal models. This thesis contributes to the characterization of the cognitive skills disruptions - as well as other behavioral alterations - in selected rat models of AD (transgenic McGill rat, non-transgenic Samaritan rat) and schizophrenia (lipopolysaccharide model of early postnatal, or prenatal, bacterial infection). The thesis also discusses the validity and limitations of these models. Our results showed a severe deficit of spatial navigation, learning and...

The aim of this study is to discover how primary scholars as substitute parents, contemplate the perceiving aspect of their substitute parenting. In the theoretical chapters the demands set for adults as primary educators and their development, are viewed. A comparative study between the primary edu­ cator and the child, rounds it off. The experiencing, giving meaning to, and the consequent involvement of substitute parents in their life-world, follow. The research design, substantiates the choice of format, methods of data col­ lection and analyses. Examples of raw data gathered from various tests are presented. Finally, the consolidated data is interpreted. The findings of this study is that substitute parents experience their tasks as being pleasant. Substitute parents are generally over involved with their siblings. This culminates in the development of a strong bond between substitute parents and younger siblings. Substitute parents require support and guidance from an adult to enable them to become adults and venture in their life-world. / In bierdie studie is die leefWereld van die substituut-ouer bestudeer. Die oorhoofse doel van hierdie studie is om met behulp van teoretiese en empiriese studies, ondersoek in te stel na substituut-ouers se belewing van bulle besondere taak. Die studie neem 'n amwang met 'n beskrywing van die primere opvoeder se verantwoordelikhede en eise. Die ontwikkeling van die volwassene word daama bestudeer. Verder Is gelet op die e1se en ontwikkeling wat aan kindwecs gelykgestel word. Die doel hiermee, is om uiteindelik 'n vergelyking te kan tref tussen die volwassene en die kind. Nadat so 'n vergclyking tussen die kind en volwassene gemaak is, sal die probleme wat die kind as substituut-ouer ervaar, oorweeg kan word. Die literatuurstudie kulmincer in substituut-ouers se unieke betekenisgewing, betrokkenheid en belewing aan en by bulle leefWereld. Dan word die literatuurstudie opgevolg deur die navorsingsontwerp, keuse van steekproef­ neming asook wyses van dataverameling en -analisering. Ten slotte word daar gekyk na die verslaggewing aangaande inligting soos bekom met behulp van die verkenningsmedia, te wete individuele onderhoude met die deelnemers aan die navorsing, die Bene-Anthony gesinsverhou­ dingstoets, die Persoonlikheidsvraelys vir kinders, die projeksiemedia van Jacobs en Vrey en die Kinestetiese huisgesinstekeninge. Die gekonsolideerde data word dan geinterpreteer en weergegee ten einde die postulate soos in boofstuk 5 uiteengesit te beantwoord. Die belangrikste bevindings van die studie is dat die taak van substituut­ ouerswees vir laerskoolkinders aangenaam is. Hierdie aangename belewing van hulle taak as substituut-ouers, dra egter nie by tot die vonning van 'n positiewe selfkonsep by die substituut-ouer nie. Substituut-ouers ervaar angs en kommer aangaande hulle substituut-ouerskap. Hulle voel nie bevoeg om as substituut-ouers op te tree nie. Substituut-ouers IS oar die algemeen oorbetrokke by hulle broers en susters. Hulle sien om na hulle sibbe, verseker dat hulle veilig is en verleen hulp aan hulle, waar nodig. Hierdie betrokkenheid veroorsaak 'n sterk band tussen die leerlinge. Hierdie sterk band wat tussen die substituut-ouers en hulle sibbe bestaan, is egter afwesig tussen die substituut-ouers en hulle eie ouers. Substituut-ouers toon dan oak teen die verwagting van die navorser in, dat hulle nie beskik oor 'n verantwoordelikheidsin nie. Substituut-ouers k:an eerder beskryf word as teruggetrokke, met min deursettingsvennoe, prikkelbaar, goedhartig, onderdanig, athanklik en inskiklik. Die studie toon ten slotte dat substituut-ouers betrokke raak by hulle taak as substituut-ouers, vanwee 'n aansporingsmiddel, te wete sakgeld. Benewens vir die bogenoemde bevindings, toon die studie oak dat die ondersteuning en begeleiding van substituut-ouers deur 'n volwassene tot volwassenheid noodsaaklik is. / Psychology of Education / M.

RESUME The times based on one individual's decision about which school to study to be able to choose further continuous and smooth career path has been over. As a result of current global and local social changes everybody should be prepared to the every possible change in career. Nevertheless the first choice of career is still an important milestone and can direct the individual career, but it is not the only key milestone, that determines the individual career once and for ever. People in contemporary world should be able to respond quickly to constant changes, evaluate new situations and be able to make the right decisions. The widespread myth is that success means to raise money as quickly as possible to guarantee the freedom and happiness. But a real success is a contented life, which is a long way over such values as for example certainty that we are doing the work that we like and which fills us with satisfaction. Individual goal is to focus on the abilities and skills so that the decision directs to such a career path where one will be able to optimally exploit one's potential in a future career. In the beginning of a career path a family as a primary socializing agent and the closest partner institution in the life of the pupil should fulfil its role in close cooperation with the school that...
