Children living in foster care are a particularly vulnerable group of children that are at high-risk for experiencing a multitude of difficulties, including poor academic performance and achievement. Although the academic underachievement of foster children has been well-documented for decades, very few attempts have been made to address the problem. This thesis is the second study to come out of the RESPs for Kids in Care research project, which represents one of three known randomized controlled trials aimed at providing an academic intervention to foster children with a view of improving their basic skills, increasing their chances of graduating from high school and enrolling in post-secondary education. Sixty-four foster children (aged 6 to 13 years), recruited from nine Children’s Aid Societies in Ontario, Canada, participated in the project and received an individualized direct-instruction tutoring intervention that was delivered by their foster parent(s). The unique contribution of the current study was its investigation of differential gender effects of the tutoring amongst the foster boys and girls, and whether there were any mental health and social-relational spillover effects. A mixed-method approach was used to explore these differential effects and the main hypothesis of the project, that the foster children in the experimental group would demonstrate greater gains in reading and math than the children in the control group, between pre-test and post-test, regardless of gender. The results were promising: the foster children in the experimental group demonstrated significant gains in their basic reading and math skills after receiving the foster-parent delivered one-on-one tutoring; there were differential gender effects across the academic and mental health results; and there was partial support for the notion that an academic tutoring intervention does elicit spill-over effects into the mental health and social-developmental domains of foster children’s lives. Results and implications were discussed.

This dissertation is composed of two essays that relate topics in the fields of labor economics, migration, experimental economics and entrepreneurship, taking into account a gender perspective. The first essay examines collective remittances, those sent by migrants' associations to be invested in community projects in their hometowns, matched by governmental funds through the Mexican program 3x1 Para Migrantes. This study evaluates the effect of collective remittances on the probability of wanting to migrate, being employed and in the labor force, and on the amount of hours worked of adult men and women in 2002 and 2005 in Mexico. Collective remittances have a positive, albeit modest, impact on the employment and labor force participation of adults in participant municipalities, but no effect on the preferences to migrate. Important differences are observed by type of project executed and by gender and age cohort, with younger men and women benefiting the most from investments in schools and sports facilities. The second essay conducts a series of laboratory experiments to test the hypothesis that, while stress worsens entrepreneurial choices and outcomes for all, it does so more for women than men. Results show that the effects of stress on choice and performance are more negative for women. Experimentally-induced stress causes more long-lasting productivity losses for women, and additional losses for making choices that do not maximize income given one's productivity. The negative treatment effect on women's productivity, choice quality, and earnings is driven by women who experienced negative life events. The mechanisms that affect choices also differ by gender. Men are more likely to present inconsistencies during a series of entrepreneurial decisions, and women to have inaccurate beliefs about their performance.

La présente thèse porte sur l’évaluation de l’efficacité d’un nouveau traitement pour le trouble de stress post-traumatique (TSPT). Le traitement a été développé selon les prémisses de la théorie de la reconsolidation des souvenirs. Il consiste en six courtes séances de remémoration de l’événement traumatique réalisées sous l’effet du propranolol, un bêtabloquant. La population de l’étude est constituée de patients souffrant d’un TSPT chronique. La thèse comporte cinq chapitres. Le premier chapitre est l’introduction, on y retrouve une description du TSPT, des traitements validés empiriquement, de diverses théories de la mémoire, d’un modèle étiologique du TSPT, d’études sur la consolidation et la reconsolidation, de la pharmacocinétique et du mécanisme d’action du propranolol,ainsi que des objectifs de la thèse. Le second chapitre est une revue critique de littérature sur la théorie de la reconsolidation. Comme l’étude du phénomène de la reconsolidation est récente, nous tentons de faire le point sur l’état des connaissances dans le domaine, dans un effort de réflexion sur la validité de la théorie. Nous proposons une série de critères permettant de différencier la reconsolidation d’autres processus connexes. Nous concluons que la théorie paraît valide, bien que d’autres études soient nécessaires afin de rendre compte de résultats négatifs publiés par le passé. Le troisième chapitre est un essai ouvert, et vise à évaluer l’efficacité d’un traitement basé sur la reconsolidation à diminuer la sévérité et l’incidence du TSPT, auprès de 42 patients souffrant d’un TSPT chronique. Le traitement consiste en six séances de remémoration de l’événement traumatique sous propranolol. Lors d’un suivi à trois mois, nous rapportons une diminution des symptômes de TSPT de 41%-56%, ainsi qu’une diminution de l’incidence du TSPT de 74%. En comparaison, seulement 2/25 patients du groupe contrôle (ayant participé uniquement aux évaluations) ne souffrent plus d’un TSPT. Dans le groupe traitement, les tailles d’effet (d de Cohen)varient entre 1.32-2.19. Le quatrième chapitre a comme objectif d’identifier des caractéristiques des patients prédisant l’efficacité du traitement, et d’explorer s’ils s’améliorent dans des domaines de santé autres que le TSPT. Nous rapportons que les femmes s’améliorent davantage que les hommes, mais que d’autres facteurs, tels que la sévérité des traits de personnalité borderline ou le type de trauma (enfance versus adulte), n’influent pas sur l’efficacité. Également, les patients s’améliorent dans les domaines de santé suivants : la qualité de vie, la symptomatologie dépressive, l’intensité des émotions négatives au rappel de l’événement traumatique et dans la vie courante. Le cinquième chapitre contient la discussion générale de la thèse. Nous effectuons une synthèse et interprétation des résultats, nous examinons les hypothèses alternatives à l’amélioration clinique et abordons des pistes de recherches futures. Nous concluons que le traitement à l’étude a été efficace dans notre échantillon de patients souffrant d’un TSPT chronique. Étant donné la méthodologie employée (essai ouvert), nous ne pouvons statuer sur le mécanisme d’action du traitement, à savoir si l’amélioration clinique a été réellement causée par un blocage de la reconsolidation des souvenirs. / This dissertation aims at exploring the efficacy of a new treatment for posttraumatic stress disorder (PTSD). The treatment was developed in accordance with an emerging theory in neuroscience, the reconsolidation theory, and it consists in six short reactivation sessions of a traumatic memory under the influence of propranolol (a ß-blocker), with patients suffering from longstanding PTSD. This dissertation includes five chapters. Chapter I is the introduction, it includes a discussion on the following topics : definition and prevalence of PTSD,empirically validated treatments in the field, memory theories, etiology of PTSD, studies on consolidation and reconsolidation, pharmacokinetics of propranolol and its mechanism of action in reconsolidation, and the objectives of the dissertation. Chapter II is a critical literature review on reconsolidation theory. We discuss some of the contradicting findings in reconsolidation, as some researchers have reported negative results in the field. We address the possibility to reconcile these discrepancies,within the scope of evaluating the validity of the theory. We also discuss a series of criterion which could provide guidance in differentiating reconsolidation from other processes. We conclude that reconsolidation theory seems valid, although more research is needed in order to shed light on some negative results that were published in the past. Chapter III is an open label trial comprising six sessions of treatment (trauma reactivation under propranolol) with 42 patients suffering from chronic PTSD. At a three-month follow-up, we report that patients have a 41% - 56% reduction in PTSD symptoms, and that 31 / 42 patients no longer meet the diagnostic threshold for PTSD. In comparison, only 2 / 25 patients from the control group (assessments only) don’t meet the diagnostic threshold for PTSD. In the treatment group, effect sizes (Cohen’s d) range between 1.32 -2.19. Chapter IV follows on the previous chapter’s study, and aims at identifying predictors of treatment outcome (i.e., predictors of the improvement in PTSD symptoms), and whether patients also improve in health domains other than PTSD. We report that women improve more than men during the treatment, but that other factors such as borderline personality severity traits or type of trauma (childhood versus adulthood) do not influence treatment outcome. Patients also improve in diverse health domains during the treatment; they have a better quality of life, less depressive symptoms, less intense negative emotions in daily life and during trauma recollection. Chapter V contains a general discussion and a conclusion. We summarize and interpret the results, we explore alternative hypotheses to the clinical improvement as well as future research directions. We conclude that this treatment yielded interesting results in our sample of patients suffering from chronic PTSD. However, our methodology (open label study) doesn’t provide any information on the mechanism of action of the treatment used in this dissertation, i.e. whether the clinical improvement was caused or not by reconsolidation blockade.

<p>Engineering students are expected to develop professional skills in addition to their technical knowledge as outcomes of accredited engineering programs. Among the most critical professional skills is the ability to work effectively in a team. Working effectively in teams has learning benefits and also provides an environment for developing other professional skills such as communication, leadership skills, and time management. However, students will develop those skills only if their teams function effectively.</p> <p>This dissertation includes three studies that together inform team formation and management practices to improve team dynamics. The first study investigates mixed-gender team dynamics to determine whether those teams are realizing their potential. The second study explores the relationship of individual psychological safety and students’ team member effectiveness and the moderating effects of team-level psychological safety. The third study explores self-rating bias among first-year engineering students and its relationship to student characteristics and dimensions of team-member effectiveness. </p> <p>Although mixed-gender teams had equal team dynamics with all-male teams, more team facilitation and training are needed to improve the experience of mixed-gender teams. Asian, Black, and Hispanic/Latino students, as well as students with lower GPA, report lower psychological safety, which is associated with lower team-member effectiveness. Team-level psychological safety moderated this effect for Asian and Hispanic/Latino students. Students’ effort in teams was associated with lower self-rating bias, likely an indication of greater self-awareness. Together, these studies and their findings contribute to a broader understanding that there are interrelationships among team composition, team dynamics, and team-member effectiveness, and that these relationships differ based on student characteristics such as race/ethnicity, gender, and prior knowledge. This work adds to the body of research demonstrating the importance of teaching students about effective teamwork, conducting regular peer evaluations of team functioning, and interpreting those peer evaluations carefully to avoid perpetuating any biases. This work also demonstrates the usefulness of psychological safety as an important indicator of marginalization.</p>

Une régression des principales modalités sensorielles (vision, audition, goût et odorat) est bien rapportée à l'âge. La perception tactile est influencée par différents paramètres. Un grand nombre de ces paramètres ont été bien étudiés dans la littérature tels que le système nerveux central, la densité des mécanorécepteurs dans la peau et les seuils de détection vibro-tactile. Ces paramètres ont été étudiés pour comprendre l'affaiblissement de la perception tactile au fil du temps et les différences naturelles entre les hommes et les femmes. Le doigt humain est toujours utilisé pour qualifier la qualité et les propriétés d'une surface. Par conséquent, un panel de différent âge et sexe est toujours utilisé par différents secteurs industriels afin de comprendre les besoins des consommateurs. Cependant, cette méthode est très coûteuse, longue et subjective. L’objectif de ce travail était de développer une méthodologie qui permette d'avoir une objectivation tactile semblable au panel, cela signifie qu'on doit prendre en compte les effets de l'âge et du sexe. Cette thèse a fourni des mesures in vivo pour 40 doigts humains. Nos développements proposent un doigt artificiel capable de mimer le doigt humain, en tenant l’effet de l'âge et du sexe. Pour atteindre notre objectif, nous avons développé plusieurs approches qui combinent à la fois, la topographie multi-échelle du doigt humain, ces propriétés mécaniques anisotropes, les propriétés tribologiques et l’effet de l’aire réelle de contact et la direction du toucher sur la force de frottement et les vibrations générées. Le développement d’un algorithme de traitement du signal, a permis d’identifier des coefficients représentatifs de la qualité de la surface touchée. L’ingénierie de l'émotion a été un autre axe de recherche dans de ces travaux. L’instrumentation du doigt humain avec un dispositif laser-doppler, a permis d’évaluer la qualité tactile des échantillons en fonction de l'émotion générée pendant le processus du toucher. Cette émotion est étudiée par la variation fréquentielle du débit sanguin. Le mise au point d’un doigt artificiel bio-inspiré qui possède des propriétés biophysiques proches du doigt humain, a permis de réaliser un démonstrateur de toucher qui peut intégrer l’âge et le sexe d’un panel. Ce dispositif répond au cahier des charges défini dans le projet ANR «plasticTouchDevice», et permet aux industriels de la plasturgie de mener des expertises de leurs innovations en ayant recours à un dispositif qui permet d’intégrer l’effet de l’âge et du sexe dans la métrologie de la qualité du toucher des matériaux plastiques. / A decline in the main sensory modalities (vision, hearing, taste, and smell) is well reported to occur with advancing age, it is expected a similar change to occur with touch sensation and perception. The tactile perception is influenced by different parameters. Many of those parameters have been well studied in the literature such as central nervous system, the density of mechanoreceptors in the skin and the vibro-tactile detection thresholds. These parameters have been studied in order to understand the weakens of tactile perception over time and the natural differences between men and women. The human finger is always used to qualify the quality and the properties of a surface. Therefore, a panel of different age and gender always used by companies in order to understand the customers’ needs. However, this method is very expensive, time-consuming and subjective. The objective of this work is to give a solution that avoid the limits of the actual method, but in the same time it should keep their advantages (age and gender). This thesis provided in vivo measurements for 40 human fingers. Our developments propose an artificial finger capable of mimicking the human finger, taking into account the effects of age and gender. To achieve our goal, we have developed several approaches that combine the multi-scale topography of the human finger, the anisotropic mechanical properties, the tribological properties, the effect of the real contact area, the direction of touch on the friction force and the vibrations generated by the human finger. The development of a new signal processing algorithm has made it possible to identify coefficients representative of the quality of the affected surface. The engineering of emotion has been another area of research in this work. Instrumentation of the human finger with a laser Doppler device, allowed to evaluate the tactile quality of the samples according to the emotion generated during the process of the touch. This emotion is studied by the frequency variation of the blood flow. The development of a bio-inspired artificial finger that has biophysical properties close to the human finger, has made it possible to realize a haptic touch demonstrator that can integrate the age and gender of a panel. This device meets the specifications defined in the ANR project "PlasticTouchDevice", and allows plastics industry to conduct expertise of their innovations by using a device that allows the integration of the effects of age and of gender in the metrology of the quality of the touch of plastic materials.

This study investigated whether girls achieve better results in Physical Science in single sex environments or in co-educational classes. Thirteen independent South African schools where children were of similar socio-economic background were considered. Grade 12 Matriculation Physical Science examination results for 1999 to 2003 were analysed using Bonferroni (Dunn) t-Tests and Scheffe's Tests. Questionnaires were completed by a small number of students in order to compare their attitudes towards Physical Science and examined qualitatively. There were significant differences found by the administration of the Bonferroni (Dunn) t-Tests and Scheffe's Tests in 2000, 2001 and 2002 to indicate that girls in single sex schools achieved better results in Science than the co-educational schools. However, in 1999 and 2003 there was no significant difference in the results achieved, and so there may be other factors that are more important predictors of achievement than whether the schools are mixed or single sex. / Educational Studies / M.Ed.

Nach dem Prinzip synchronisierter Reimwörter wurde ein deutscher dichotischer Hörtest entwickelt und erprobt (Fused Words, FW10b). Die Reliabilitätskennwerte lagen für die innere Konsistenz bei alpha=0,89 und für die Re-Test-Reliabilität im Bereich von r-tt=0,67 bis r-tt=0,87. Der dichotische Test korrelierte hoch mit einem Paralleltest (r=.73, FW12k). In mehreren Untersuchungen fand sich keine Assoziation des dichotischen Lateralisationsergebnisses mit dem Hormonzyklus bei Frauen. Zwischen der Klassifikation im Wada-Test und der Klassifikation im dichotischen Test wurde eine hohe prozentuale Übereinstimmung beobachtet (91%). Auch in einer externen Studie wurde eine hohe Konkordanz mit einem fMRT Paradigma gefunden (97%, Hund-Georgiadis et al 2002). Unter Rechtshändern hatten 70% einen Rechts-Ohr-Vorteil, 23% einen Links-Ohr-Vorteil; bei 7% wurde kein Ohr-Vorteil beobachtet. Es bestand eine hohe Assoziation zwischen dem Lateralitätsquotient der Händigkeit und dem Lateralitätsindex Lambda aus dem dichotischen Test (R=0,76, r=0,72). Bei epilepsiechirurgischen Kandidaten mit links- oder rechtsseitigen Temporallappenläsionen, die alle durch einen Wada-Test als unilateral links-hemisphärisch sprachdominant kategorisiert worden waren, wurden Läsionseffekte analysiert (Hippocampus-Sklerose vs. extra-hippocampale Läsionen). Wie erwartet ergaben sich massive Läsionseffekte für die Patienten mit den Läsionen in der linken sprachdominanten Hemisphäre. In der linken extra-hippocampalen Untergruppe kam es zu einer signifikanten Abnahme der Rechts-Ohr-Punkte und gleichzeitig zu einem signifikanten Anstieg der Links-Ohr-Punkte. Die Einbeziehung von neokortikalen und anderen extra-hippocampalen Strukturen in die temporalen Läsionen war von entscheidender Bedeutung für die Unterdrückung der Antworten vom kontralateralen (rechtsseitigen) Ohr. Die Zunahme der Links-Ohr-Punkte in der Gruppe mit linksseitigen extra-hippocampalen Läsionen deutet eine kompensatorische Verlagerung von Sprachfunktionen auf die rechte Hemisphäre an, die durch den Wada Test nicht erfasst wurde. / Following the principle of synchronized rhyming words a German dichotic listening test was developed and tested (fused words, FW10b). Reliability coefficients for the inner consistency were at alpha=0,89 and for the re-test-reliability between r-tt=0,67 and r-tt=0,87. The dichotic test FW10b was highly correlated with a parallel test (r=.73, FW12k). None of several studies did show any association between the dichotic language lateralization and the hormonal cycle in women. A high percentage of agreement was observed between the Wada classification and the classification by the dichotic test (91%). Furthermore Hund-Georgiadis et al. (2002) found a high percentage of concordance with the lateralization by a fMRI paradigm in an external study (97%). Among right-handers 70% showed a right ear advantage, 23% had a left ear advantage, and 7% had no ear advantage. There was a high association between the laterality quotient of the handedness inventory and the laterality index Lambda of the dichotic listening test FW10b (R=0.76, r=0.72). Lesion effects were analyzed in epilepsy surgical candidates with left and right temporal lobe lesions (hippocampus sclerosis vs. extra-hippocampal lesions), who were all categorized as left-hemispheric language dominant by a Wada-test. As expected, massive lesion effects were apparent in those patients who had their lesions in the left language dominant hemisphere. In the subgroup with left extra-hippocampal lesions there was a significant decrease of right-ear-points and at the same time a significant increase of left-ear-points. The involvement of neocortex and other extra-hippocampal structures in temporal lobe lesions were of crucial importance for the suppression of contralateral (right) ear responses. The elevation of left-ear-points in the left-lateral group indicated a partial compensational shift of language functions to the right hemisphere, which was not detected by the Wada procedure.
