In order to obtain a closer look into the relationships between an at-risk populations’ family stressors and future school problem behaviors, a Latent Class Analysis (LCA) of family stressor variables was performed on at-risk elementary school girls from Health Zone 1. Participants were 308 girls with a mean age of 8.79 years. The dataset was inherited from the Delores Barr Weaver Policy Center and analyses were run to uncover latent classes of family stressors. Class membership was then utilized to predict future behavioral referrals and suspensions from school. A total of three classes emerged from the LCA: “Exposure to Trauma”; “Familial Stress”; and “Stable Home.” Chi-square analysis between class membership and future behavioral referrals and suspensions failed to reach significance. However, chi-square analyses between class membership and some future family stressors were significant. It appears that latent classes of stressors can be uncovered, and these classes can be utilized in the meaningful prediction of outcome variables. Implications for researchers and policy makers are discussed.

The research revolves on the emergence of globalisation, change, competition, work pressure, and risks among others which have exposed insurance employees to work stress that can interfere with home activities. The research purpose was to determine the relationship between work stress, work-home interference, and organisational culture among insurance employees in the Zimbabwean context. The sample consisted of 240 participants, from which data was collected from 190 employees who responded to the questionnaires. The questionnaires were analysed using SPSS, internal consistency reliability analysis, and the inter-correlation analysis. The inferential statistics used were multiple linear regression and one way ANOVA. Substantial positive and negative correlations were noted for the six sub-scales of the Occupational roles questionnaire (ORQ), negative work-home interference (NWHI) and positive work-home interference (PWHI) scales, and the three sub-scales of the Organisational culture index (OCI). The research concluded that different measures should be taken to manage work stressors, depending on the organisational culture, and its employees to prevent spill-over which contributes to negative work-home interference. / Industrial and Organisational Psychology / M.

Dual career (DC) means that an athlete combines sport and study/work. A balanced DC strongly depends on an athlete's ability to cope with stressors and is of paramount importance to succeed with both studies and sport (Stambulova et al., 2015; Wylleman & Reints, 2010). The study aimed to explore dual career (DC) motivation, stressors, and coping in Swedish football players. The participants were nine male student-football players from seven football clubs in Sweden aged between 22 to 27 (M = 24.84, SD = 1.50) in Division 1, Superettan, and Allsvenskan (three highest levels of football in Sweden). A semi-structured interview guide was designed to explore the study’s aim.      Based on the result, a thematic map was developed from the central concept, categories, themes, and sub-themes created from analyzing the corresponding data. The thematic map connects all parts of the results and summarizes the study. The results revealed that internal DC motivation dominated, but education was partly affected by external motivation. Lack of support, dealing with time pressure and the challenge with performance and pressure in DC were the most significant stressors. Student-athletes demonstrated different ways of coping with stressors. Three coping strategies were identified. The participants highlighted physical and mental recovery in DC and the importance of social support. Findings showed that Covid-19 (C-19) positively impacted education, where remote learning was beneficial. The discussion, therefore, highlights the recommendations for flexible academic programs for all student-athletes at university to facilitate DC. The study concluded that internal motivation, combined with social support and previous experiences, is the predominant factor in succeeding with DC. / Dubbel karriär (DC) betyder att en idrottare kombinerar sport och studier/arbete. En balanserad DC beror starkt på idrottarens förmåga att hantera stressfaktorer och är en avgörande faktor för att lyckas med både studier och sport (Stambulova et al., 2015; Wylleman & Reints, 2010). Syftet med studien var att utforska svenska studerande fotbollsspelares erfarenheter med fokus på motivation, stressorer och stresshantering. Deltagarna bestod av nio manliga studerande fotbollsspelare, från sju olika fotbollsklubbar i Sverige vars ålder varierade mellan 22 till 27 (M = 24,84, SD = 1,50) i Division 1, Superettan och Allsvenskan (tre högsta fotbollsligorna i Sverige). En semistrukturerad intervjuguide designades för att studera syftet. Baserat på resultatet utvecklades en tematisk karta utifrån de kategorier, teman och sub-teman som uppkom av den analyserade datan. Den tematiska kartan är studies produkt som sammanfattar resultatet och hur de sammankopplade. Resultatet påvisar att dubbla karriärer drivs mer från inre motivation, men utbildning påverkas delvis av yttre motivation. Brist på stöd, hantering av tidspress och utmaningarna med prestation och krav inom DC var de största stressorer. Student-idrottare demonstrerade olika sätt att hantera stressfaktorer och tre hanteringsstrategier identifierades. Deltagarna lyfte fram fysisk och mental återhämtning i DC och vikten av socialt stöd. Resultaten visade att Covid-19 (C-19) påverkade utbildningen positivt, där distansundervisning var fördelaktig. Diskussionen vill därför lyfta fram rekommendationerna för flexibla akademiska program för alla studentidrottare vid universitetet för att underlätta DC. Studien drog slutsatsen att intern motivation, kombinerat med socialt stöd och tidigare erfarenheter, är de dominerande faktorerna för att lyckas med DC.

RÉSUMÉ Les joueuses de hockey professionnelles au Canada ne sont pas intégrées dans un circuit professionnel conférant les statuts, privilèges et protections similaires à leurs homologues masculins évoluant dans la Ligue nationale de hockey. Malgré que ces joueuses dédient une quantité énorme de temps et de ressources à leur emploi de hockeyeuse, il demeure un emploi d’appoint faiblement rémunéré, sans possibilité de filet social et comptant une multitude de facteurs propices à l’émergence d’atteintes à la santé physique et mentale. Ceci pose des enjeux importants pour ces femmes en termes d’interface entre leur emploi principal, leur emploi de hockeyeuse et leur vie personnelle. En adoptant une approche écologique dans l’analyse de ce phénomène, ce mémoire vise à comprendre comment les joueuses professionnelles de hockey se représentent leur interface travail-vie personnelle (ITVP) en marge des atteintes potentielles à la santé mentale et physique connues dans le sport professionnel. Partant de l’analyse de contenu de dix entrevues semi-dirigées menées en 2022, nos résultats montrent que l’ITVP des joueuses s’avère essentiellement conflictuelle puisqu’elles ne sont pas munies des ressources nécessaires pour répondre aux demandes environnementales (p. ex. : nécessité d’avoir un emploi principal, manque de financement, etc.), sont soumises à plusieurs facteurs de risque organisationnels (p. ex. : salaires insuffisants, installations sportives inadéquates, etc.) et qu’elles n’évoluent pas nécessairement dans un environnement qui les protège de ces risques. Cependant, des facteurs de protection importants atténuent aussi cette relation conflictuelle pour les joueuses (p. ex. : « l’effet de la chambre de hockey », motivation accrue, etc.). L’approche qualitative mise de l’avant permet de brosser un portrait encore inédit de la réalité de ces joueuses à l’égard de leur interface travail-vie personnelle. Cette recherche contribue à l’avancement des connaissances chez ces travailleuses au statut particulier notamment par l’identification des antécédents à leur ITVP, tant dans son expression conflictuelle que d’enrichissement, le tout en précisant leurs fonctions respectives (stresseurs ou ressources). / ABSTRACT Professional women hockey players are not integrated into a professional circuit that provides similar status, privileges and protections as their male counterparts in the National Hockey League. Although these players dedicate an enormous amount of time and resources to their job as professional hockey players, it remains an underpaid side job with no social safety net and they encounter a multitude of risk factors that contribute to the emergence of physical and mental health issues. This poses a significant challenge for these women in terms of the interface between their main job, their professional hockey career and their personal life. Using the ecological approach in the analysis of this phenomenon, this thesis aims to understand how professional women hockey players experience their work-life interface (WLI) with regards to the potential mental and physical health problems known in professional sport. Based on the content analysis from ten semi-structured interviews conducted in 2022, our study shows that women hockey players' interface is mostly conflictual. This primarily due to the lack of resources they possess to meet environmental demands (e.g., need to have a primary job, lack of funding, etc.), multiple organizational risk factors (e.g., insufficient salaries, inadequate sports facilities, etc.), and they do not operate in an environment that protects them from these risks. However, we note that there are protective factors that mitigate the conflictual dyad for the players (e.g., the "the locker room effect", increased motivation, etc.). The qualitative approach used in this study provides an unprecedented picture of the reality of these players with respect to their work-life interface. This research contributes to the advancement of knowledge about these workers with a special status, in particular by identifying the antecedents of the players' WLI and by the fact that we were able to specify the function (stressors or resources) of the antecedents identified.

Using a high throughput closed respirometry method to measure oxygen consumption, I determined metabolic rates in asexual and sexual Schmidtea mediterranea and Girardia dorotocephala, as a function of temperature, taxon, stressors, reproductive mode, age, regeneration, and specific dynamic action. This study has shown that oxygen consumption can reliably be measured in planaria using optode closed respirometry, and also provided a reliable method for measuring wet mass in planaria, which has been a challenge to researchers in the past. This research revealed that oxygen consumption in S. mediterranea is 1.5-2.1X greater in the sexual strain over the asexual strain at 13-18°C. Within the sexual strain, oxygen consumption is 1.5 -2.2X greater in sexually mature adults over the sexually immature groups (hatchlings, juveniles, and regenerating sexuals). Furthermore, I was able to quantify differences in sexual morphology between these groups exhibiting significant differences in oxygen consumption. The results of this research supports a theory of higher metabolic costs with sexual maturity in S. mediterranea. Therefore, this study has established sexual and asexual S. mediterranea as simple, yet attractive models for investigating energetic costs between sexual and asexual phenotypes. This research also provided quantitative values for specific dynamic action in planaria, with a maximum increase in oxygen consumption of 160% induced by feeding, as well as metabolic relationships in planaria involving temperature, age, and regeneration. These values establish planaria as one of the simplest animal models in which common metabolic patterns, such as SDA and poikilothermic temperature sensitivity, have been demonstrated. Therefore, this research has contributed to the overall knowledge of the basic physiology in this animal, providing the framework for future metabolic studies in planaria involving environmental factors, reproduction, regeneration, development, and aging. Information from this study may supplement interpretation and understanding of modern cellular, molecular, and genomic studies in planaria.

Methane (CH4) is guaranteed to affect climate change and is essential in rising temperatures. Scientists have known for over two decades that wetlands emit CH4 to such an extent that it affects our climate. Tropical trees that grow in wetlands tend to emit or act as a conduit of CH4, to the extent that it has a negative environmental impact. However, until this study, no one has examined whether wetland species growing in another environment have the same effects. Hence, this thesis aimed to collect data from wetland-adapted tropical trees in a non-wetland environment, namely the Botanical Garden in Rio de Janeiro. The results showed a difference in the sampling height of the stem, namely that a decrease in emission is seen with an increased height. All the species except one (Pseudobombax munguba) showed both assimilation and emission from the day-to-day measurements of CH4, which speaks for the trees acting both as a sink and a source of CH4. This suggests that the species are more robust than the environmental stressors in a non-wetland environment. Previous studies have found that increased CH4 emissions can be seen with different meteorological parameters. The results presented in this thesis show the opposite, that some species tend to emit less or assimilate more CH4 during days with increased rainfall, humidity, and temperature.

Summaries in English and Afrikaans / Text in English / A modem "disease", stress is a universal and eternal problem in the pedagogic situation, where the child becomes an aduh, under adult supervision. Stress - a feeling of pressure or strain - is a problem for contemporary South African children, who automatically respond to stressors (causes of stress), in the same way as children of the past, since human beings have not changed psychobiologically over the millennia. Our bodies and minds should return to a calm state, after our initial stress reaction, but we often remain under stress, which results in emotional/ physical symptoms of distress. Yet history has shown that children can be helped to handle stress, making it a stimulus for growth. Although past societies were not directly conscious of the concept of stress, they taught coping mechanisms to their children. Some of these are generally valid, and provide us with solutions to the problem of stress in the pedagogic situation. / Die modeme "siekte", stres, is eintlik 'n universele en altyddurende probleem in die pedagogiese situasie - die· situasie waar die kind besig is om onder volwasse begeleiding 'n volwassene te word. Stres - 'n gevoel van druk en oorspanning - is 'n probleem vir hedendaagse Suid-Afrikaanse kinders wat maar, net soos die kinders in die verlede, outomaties reageer op "stressors" (faktore wat stres veroorsaak). Die afgelope millenniums het immers bewys dat die mens nie psigobiologies verander het nie. Ons liggaam en gees behoort mstig te word na 'n aanvanklike stres reaksie.
