In recent decades there has been a push to try and include communities in natural resource conservation initiatives. This thesis uses a multidisciplinary approach and a series of case studies in the Ecuadorian Amazon to look at the role that common property regimes can have in conservation initiatives. Results show that community managed forests can have positive conservation outcomes. Local communities, however, will often integrate into local market economies creating significant tradeoffs between livelihoods, local management decisions and natural resource conservation. Nonetheless, resource scarcity can drive the evolution of local resource management institutions and communities have the potential to accurately monitor changes in natural resources. These results suggest that local communities have the potential to play an important role in conservation practices but that local economic incentives can affect the way in which communities manage their resources.

Our study investigates when people quit playing unaltered Valheim (2021) and what the inciting factors were among those frustrations. Research into occurrences of frustration helped us gain a better understanding of how players' expectations come into play as well as how players allocate their resources when it comes to video games. This understanding allows game developers to mitigate frustration in open-world survival games. The study was conducted by interviewing participants who had played the game for more than 25 hours and had quit playing unaltered Valheim (2021). The participants were obtained from a survey used to screen potential candidates for the interviews. We approach this study through the lens of Conservation of Resource theory and Need Frustration. We observed that participants' prior experience in games played a significant role, apart from the gameplay itself, in deciding whether the game they played was worth the resources they chose to invest. Ultimately, the participants felt that the game was being unfair towards them and to continue playing the unaltered game would be a waste of resources.

Non-family employees are indispensable resources for family firms as they grow. However, despite the recent scholarly attention toward non-family employees, it is still not clear how such important human resources should be managed and/or retained in family firms. To add to the limited body of knowledge on non-family employees working at family firms, this dissertation highlights the role of family-friendly workplace practices in preventing turnover intentions of non-family employees based on conservation of resources theory. Drawing on a sample of 116 dyad data (family business owner - non-family employee), this dissertation shows that family-friendly workplace practices prevent turnover intentions of non-family employees through decreased burnout. Moreover, it is found that family-friendly workplace practices in the family firms are affected by family influence. Thus, this dissertation not only creates avenues for future research on non-family employees, but also provides insight into the critical role of family-friendly workplace practices in the family firms.

Les tubercules andins oca (Oxalis tuberosa Molina), ulluco (Ullucus tuberosus Caldas) et mashua (Tropaeolum tuberosum Ruiz & Pav.) sont des espèces tubéreuses cultivées originaires des régions hautes des Andes, où elles revêtent une importance particulière aux niveaux alimentaire, agronomique, culturel et économique. La diversité génétique au sein de ces espèces est très grande, mais est menacée d'érosion génétique. Dans ce contexte, notre étude s'est basée sur des échantillons de oca, ulluco et mashua, maintenus dans des système de conservation in situ et ex situ au Pérou et en Bolivie, dans l'objectif de contribuer à la conservation efficace (in situ et ex situ) de ces espèces négligées. Cette étude a combiné les connaissances autochtones andines, ainsi que des données agronomiques, morphologiques et moléculaires. Nous avons montré que l'agriculture andine conserve une grande diversité au niveau inter-spécifique, mais aussi au niveau intra-spécifique, en terme de nombre de variétés locales. Nous avons également mis en évidence de la présence de variétés hétérogènes, la congruence entre les données moléculaires et morphologiques, et une structure génétique influencée par la provenance géographique. Enfin, nous avons compilé l'ensemble de nos résultats dans un modèle récapitulatif. Nous avons montré l'importance des caractéristiques intrinsèques de l'espèce (mode de reproduction), ainsi que les spécificités du système agricole andin (socioculturels, économiques et environnementales). Cette étude a contribué de manière significative à la compréhension de la diversité génétique et de la structure des tubercules andins.

Rheumatoid arthritis (RA) is a chronic, deteriorative disease, which leads to psychological distress. &lsquo / Conservation of Resources theory (COR)&rsquo / is a relatively recent stress model, developed by Hobfoll (1988, 1989). This resource-oriented theory is based on the assumption that psychological stress is a reaction to a threat of loss of resources, loss of resources and/or lack of resource gain after investment in resources. Religiousness, coping abilities, coping self-efficacy and social support are very important personal resources, which have been found to protect individuals against psychological distress. The aim of the present study was to examine the predictive values of socio-demographic and illness related variables, religiousness, perceived social support, ways of coping, resource loss and arthritis self efficacy for both psychological distress (anxiety and depression) and posttraumatic growth (PTG) of RA patient. In addition, the COR theory was tested for a chronic debilitating illness. Data were collected by administering eight scales to one hundred and seventeen RA patients in the Rheumatology and Physical Medicine and Rehabilitation Clinics of Ankara Numune Hospital. As a result of the regression analysis, it was found that being female, fatigue, resource loss, helplessness coping and perceived social support were significant predictors of anxiety. Impact of illness on daily activities, resource loss, problem solving coping and arthritis self-efficacy were significant predictors of depression. Gender, perceived severity of the illness, perceived social support and problem solving coping were significant predictors of PTG. Perceived social support was not related to depression and total psychological distress whereas it was related to anxiety and PTG. Religiousness was not related to psychological distress and PTG. The results of the study were discussed within the relevant literature, shortcomings of the current study, clinical implications and suggestions for future research were proposed.
