I explore students‟ motivations towards using Computer Algebra Systems (CAS) in learning mathematics, their associated actions and the relationship between their motivations and actions. Leontiev‟s (1978) philosophy of needs, motives and goals provides a powerful theory within which to understand students‟ motivations and actions in a learning context mediated by tools, thus the study is located within the framework of Leontiev‟s activity theory. It draws particularly on his notions of activity, actions and operations, as well as on Western motivational concepts of achievement goal theory and expectancy-value theory. Specifically, the notions of mastery approach goal-orientations, performance approach goal-orientations and social goal-orientations are examined, as are task value components (comprising „importance‟ of task, intrinsic reasons and extrinsic utility value). I also discuss indexes of motivation, which comprise choice of tasks, effort and persistence. An important theoretical contribution of this thesis lies in the elaboration of the aforementioned Western motivational constructs to the activity theoretical construct of motives. The latter conception comprises three groupings: self-related, cognitive and social motives, as postulated by the activity theorist Lompscher (1999). Set within the qualitative research paradigm, this study utilises case study methodology. Methods of data collection include four interviews for each of the three participants, observations of the participants during two problem-solving sessions, and consequent computer screen analyses of these sessions. The mathematical problems involved the numerical solutions of differential equations using MATLAB. The participants were students studying towards vocational (diploma) qualifications in Mechanical and Electrical Engineering at a comprehensive university in South Africa. My research illustrates the relationship between the expressed needs, motives and goals of the individuals regarding their involvement in the activity of using MATLAB in mathematical learning within a third semester, Mathematics 3 service course.

Although there appears to be increasing popularity in neuropsychology across disciplines of study, only modest work has been conducted with preschool and schoolage children. Changes in the structure of cognitive processes during early childhood and the extent of frontal lobe maturation are important to consider when conducting assessments with young children. Many neuropsychological theories, however, are based primarily on adult research (e.g., Luria’s theory) and respective assessment measures are often the extension or slight modification of items from adult assessments. Because adults and children differ on a number of neuropsychological measures, especially at younger ages, the same underlying constructs and interpretive strategies may not be appropriate for use with young children. The CAS and NEPSY are two assessment measures based on Luria’s theory; however, each posits a different conclusion regarding the number of factors that explain neuropsychological functioning in young children. Luria asserted that neuropsychological functioning is comprised of three functional units, while Naglieri and Das (e.g., CAS) suggested a four factor model, and the authors of the NEPSY declared a five factor model of functioning. Due to the emerging development of a child’s frontal lobes, and the inconsistency regarding the number of factors related to neuropsychological functioning in young children, this study examined the CAS and NEPSY using factor analyses and model fit indices to determine the underlying structural model(s). The study also examined the usefulness of combining specific subscales from the CAS, NEPSY, and Peabody Picture Vocabulary Test-III (PPVT-III; Dunn & Dunn, 1997) to create a cross-battery approach to assessing neuropsychological functioning in young children. In addition to the CAS, NEPSY, and PPVT-III, data was obtained from the Behavioral Assessment System for Children (BASC; Reynolds & Kamphaus, 1992), and the Behavior Rating Inventory of Executive Function (BRIEF; Gioia, Isquith, Guy, & Kenworthy, 2000) to gather background information and to assess parent and teacher ratings of behavioral and neuropsychological functioning.

Orientador: Maria Cano / Resumo: As leishmanioses são doenças tropicais negligenciadas, causadas por protozoários do gênero Leishmania. Elas são consideradas pela Organização Mundial da Saúde como uma doença endêmica em muitos países, incluindo o Brasil. Assim, a busca por novas metodologias de combate e controle dessas doenças parasitárias se faz necessária. Uma das abordagens refere-se ao estudo da biologia molecular dos parasitos causadores da doença, como o estudo dos telômeros, os quais são repetições em tandem associadas a proteínas e localizadas nas extremidades dos cromossomos da maioria dos eucariontes. Sua função é diferenciar os terminais de cromossomos das quebras de DNA em dupla fita e assim proteger tais extremidades da degradação e dos mecanismos de reparo das células, que em muitos casos resulta na perda de material genético codificante ao fim de cada ciclo celular. Os estudos da biologia telomérica de Leishmania têm auxiliado bastante no entendimento deste organismo, no qual o complexo telomerase é composto minimamente por um componente proteico, TERT, e por um RNA, TER, sendo que a caracterização funcional destes componentes é uma das metas de nosso grupo de pesquisa. Tal caracterização tende a ser feita, principalmente, por meios de compostos inibitórios específicos da função desses componentes ou por meio de manipulação gênica, tal qual a tecnologia CRISPR-Cas, que tem possibilitado alterações genômicas precisas e pontuais bem como o silenciamento rápido e específico de genes em diferente...

Thus, the search for new alternatives to combat and control these parasitic diseases, are necessary. One of the current potential approaches are to study the biology of telomeres, which are tandemly repeated sequences associated with proteins located at the ends of the chromosomes of most eukaryotes. The main function of telomeres is to differentiate the chromosome end termini from double-stranded DNA breaks and thus, to protect the ends from degradation and damage repair mechanisms, which, at the end of each cell cycle, can result in loss of genetic material. The telomere biology studies of Leishmania have greatly improved our knowledge about this organism, in which the telomerase complex is composed minimally by a protein component, TERT, and by an RNA, TER. The functional characterization of these components is one of the goals of our research group. Such characterization is usually done by using inhibitory compounds specific to the function of these components or by gene manipulation, such as the CRISPR-Cas technology, which has enabled precise genomic alterations as well as the rapid and specific silencing of genes in different organisms, including Leishmania. Thus, we sought to observe the effects of inhibiting the L. major telomerase activity, using a specific TERT inhibitor, called BI... (Complete abstract click electronic access below) / Mestre

Titre de l'écran-titre (visionné le 17 avril 2024) / L'objectif de ce mémoire est d'étudier un terrier produit pour le monastère de l'Île-Barbe, près de Lyon, au milieu du XIVᵉ siècle à partir de la copie notariée qui en fut dressée un demi-siècle plus tard. Ce manuscrit rassemble les reconnaissances des cens dus à l'abbé de l'Île-Barbe par les habitants de trois localités situées autour du monastère. Comment expliquer la production d'un tel terrier ? Et qu'est-ce que ce manuscrit spécial au regard de notre conception habituelle de ces registres peut nous apprendre sur le genre documentaire en général ? Afin de répondre à ces interrogations, le présent mémoire entend mener une étude approfondie du manuscrit, ce qui comprend d'une part une analyse matérielle du codex et d'autre part une analyse de contenu. À terme, on espère que les résultats apportés ici pourront servir de socle à une relecture intégrale du terrier médiéval, dont le rôle social n'était peut-être pas celui qu'on croyait.
