Social competence following mild head injury and moderate traumatic brain injury: Investigating the neuropsychological relationships between arousal, social decision-making and depression

Client-directed long-term rehabilitative goals and life satisfaction following head injury emphasize the importance of social inclusion, rather than cognitive or physical, outcomes. However, very little research has explored the socio-emotional factors that pose as barriers to social reintegration following injury. This study investigates social barriers following head injury (i.e., decision-making - Iowa Gambling Task [IGT] and mood – depression) and possible amelioration of those challenges (through treatment) in both highly functioning university students with and without mild head injury (MHI) and in individuals with moderate traumatic brain injury (TBI). An arousal manipulation using emotionally evocative stimuli was introduced to manipulate the subject’s physiological arousal state. Seventy-five university students (37.6% reporting a MHI) and 11 patients with documented moderate TBI were recruited to participate in this quasi-experimental study. Those with head injury were found to be physiologically underaroused (on measures of electrodermal activation [EDA] and pulse) and were less sensitive to the negative effects of punishment (i.e., losses) in the gambling task than those without head injury, with greater impairment being observed for the moderate TBI group. The arousal manipulation, while effective, was not able to maintain a higher state of arousal in the injury groups across trials (i.e., their arousal state returned to pre-manipulation levels more quickly than their non-injured cohort), and, subsequently, a performance improvement was not observed on the IGT. Lastly, head injury was found to contribute to the relationship between IGT performance and depressive symptom acknowledgment and mood status in persons with head injury. This study indicates the possible important role of physiological arousal on socio- emotional behaviours (decision-making, mood) in persons with even mild, non-complicated head injuries and across the injury severity continuum.

The Mediating Role of Perceived Scholastic Competence in the Relationship Between Motor Coordination and Academic Performance

Children with developmental coordination disorder (DCD) are often referred to as clumsy because of their compromised motor coordination. Clumsiness and slow movement performances while scripting in children with DCD often result in poor academic performance and a diminished sense of scholastic competence. This study purported to examine the mediating role of perceived scholastic competence in the relationship between motor coordination and academic performance in children in grade six. Children receive a great deal of comparative information on their academic performances, which influence a student's sense of scholastic competence and self-efficacy. The amount of perceived academic self-efficacy has significant impact on academic performance, their willingness to complete academic tasks, and their self-motivation to improve where necessary. Independent t-tests reveal a significant difference (p < .001) between DCD and non-DCD groups when compared against their overall grade six average with the DCD group performing significantly lower. Independent t-tests found no significant difference between DCD and non-DCD groups for perceived scholastic competence. However, multiple linear regression analysis revealed a significant mediating role of 15% by perceived scholastic competence when examining the relationship between motor coordination and academic performance. While children with probable DCD may not rate their perceived scholastic competence as less than their healthy peers, there is a significant mediating effect on their academic performance.

An Abstract Algebraic Theory of L-Fuzzy Relations for Relational Databases

Classical relational databases lack proper ways to manage certain real-world situations including imprecise or uncertain data. Fuzzy databases overcome this limitation by allowing each entry in the table to be a fuzzy set where each element of the corresponding domain is assigned a membership degree from the real interval [0…1]. But this fuzzy mechanism becomes inappropriate in modelling scenarios where data might be incomparable. Therefore, we become interested in further generalization of fuzzy database into L-fuzzy database. In such a database, the characteristic function for a fuzzy set maps to an arbitrary complete Brouwerian lattice L. From the query language perspectives, the language of fuzzy database, FSQL extends the regular Structured Query Language (SQL) by adding fuzzy specific constructions. In addition to that, L-fuzzy query language LFSQL introduces appropriate linguistic operations to define and manipulate inexact data in an L-fuzzy database. This research mainly focuses on defining the semantics of LFSQL. However, it requires an abstract algebraic theory which can be used to prove all the properties of, and operations on, L-fuzzy relations. In our study, we show that the theory of arrow categories forms a suitable framework for that. Therefore, we define the semantics of LFSQL in the abstract notion of an arrow category. In addition, we implement the operations of L-fuzzy relations in Haskell and develop a parser that translates algebraic expressions into our implementation.

Relations entre les orthophonistes et les proches de personnes aphasiques en contexte de réadaptation

Le rôle que jouent les services orthophoniques dans l’ajustement des proches de personnes aphasiques ainsi que le contexte dans lequel les orthophonistes mettent en place des interventions auprès de ces proches ne sont actuellement pas connus. La présente thèse a donc pour but de comprendre de quelle manière les relations entre les orthophonistes et les proches de personnes aphasiques, développées en contexte de réadaptation, s’inscrivent dans la trajectoire dynamique des proches et dans la pratique des orthophonistes. Une approche qualitative par théorisation ancrée a été utilisée dans quatre études pour analyser les entrevues effectuées auprès de proches de personnes aphasiques et d’orthophonistes. Dans l’étude 1, les entrevues menées à trois reprises dans la première année suivant l’accident vasculaire-cérébral (AVC), et ce, auprès de quatre filles dont la mère est aphasique, ont été analysées. Un modèle théorique représentant la relation mère-fille a été développé. Ce modèle illustre que les perceptions de fragilité, de difficultés et de compétence, qu’ont les filles à l’égard de leur mère, les amènent à adopter des comportements de protection ou de confiance, ce qui génère des réactions de satisfaction ou d’insatisfaction chez la mère, renforçant alors les perceptions initiales des filles. Quatre patterns relationnels peuvent donc coexister au sein d’une même dyade. L’aphasie complexifierait cet ajustement relationnel. Dans l’étude 2, les entrevues effectuées à trois reprises durant la première année suivant l’AVC, auprès d’une fille dont la mère est sévèrement aphasique, ont été analysées. Un modèle théorique représentant l’expérience d’aider a été élaboré. Selon ce modèle, percevoir des difficultés chez sa mère et ressentir que leur relation antérieure est menacée a déclenché le processus d’aide chez la fille. Parallèlement, la reconnaissance de la compétence de sa mère a motivé la fille à offrir de l’aide visant à rendre sa mère heureuse et à favoriser son indépendance. Ce type d’aide a contribué à augmenter l’indépendance de sa mère, à retrouver une relation satisfaisante avec celle-ci et à s’adapter à l’aphasie. Dans l’étude 3, les entrevues de 12 proches de personnes aphasiques ont été analysées. Un modèle théorique représentant l’expérience de l’aphasie et de la réadaptation post-AVC a été développé et illustre que les proches sont centrés sur la personne aphasique et participent à la réadaptation dans le rôle d’aidant. Cette disposition influence alors leurs attentes envers la réadaptation, leurs interactions avec les professionnels, dont les orthophonistes, et leur appréciation de la réadaptation. Dans l’étude 4, les entrevues effectuées auprès de huit orthophonistes travaillant en réadaptation ont été analysées. Un modèle théorique illustrant le processus d’intervention des orthophonistes auprès des proches de personnes aphasiques a été construit. Pour les orthophonistes, le travail avec les proches est majoritairement perçu comme un ajout positif, mais exigeant, à leur pratique de base centrée sur la personne aphasique. Une satisfaction professionnelle peut en découler, mais des idéaux non-atteints peuvent persister. La relation proche-orthophoniste serait donc principalement axée sur le rôle d’aidant que joue le proche, et ce, en raison de leur expérience respective. Un agrandissement du territoire de rencontre entre les orthophonistes et les proches pourrait soutenir les proches dans les ajustements relationnels induits par l’AVC avec aphasie ainsi que permettre aux orthophonistes d’atteindre leurs idéaux.

Student self-assessment a feedback seeking strategy through competence evaluation

There is a body of literature that suggests that student self-assessment is a main goal in higher education (Boud et al., 1995; Tan, 2008); moreover new forms of work organization require a high level of skills and competences. The efforts to deal with competence gaps could be developed at many levels, such as employers, educational institutions, individuals and public agents. Employers could put into practice competence development programs to moderate these gaps. Educational institutions can restructure the curriculum to support students in attaining the competences that are essential in the labour market. Individuals themselves may deploy their resources (time and money) in general or specific competence training. Further, government agencies could fund competence promotion programs. Such challenges for education drive change in learning curricula and method, to properly include the competences required for developing global workers who can move beyond basic competence, to enhanced flexibility and adaptability. In performance assessment methods, there is a shift from the traditional exam-based assessments to more innovative task assessment, which considers performance in multiple different tasks carry out by students. ICTs make it technologically feasible to carry out a complete and complex selfassessment of competences, which provides immediate results to students or other recipients. In the case of students, the evaluation of competences is relevant as developing competences is part - if not all - of the objectives of education. Therefore, it is an important element of the quality of educational organizations (e.g., universities), and of their organizational success. Further, educational organizations may put special emphasis on some differentiating competences, which can be a means of positioning and differentiation from competitors. Competence assessment is an instrument to make students conscious of their strengths and weaknesses, leading to higher motivation to develop their own learning career
