From Culture to Capability : An Exploratory Study on the Impact of Organizational Culture on Self-leadership DevelopmentKolehmainen, Linus, Olsson, Petter January 2024 (has links)
Abstract Background: The workplace has grown increasingly complex during recent years, posing new challenges for competitors on the market. To ensure that organizations thrive, companies are focusing and spending more time and energy on building and sustaining a healthy organizational culture. Yet, it remains equally important for employees to be autonomous and to practice self-leadership. This study delves deeper into the relationship between organizational culture and self-leadership, exploring how organizations can bolster the self-leadership development of employees through organizational culture. Purpose: The purpose of this study is to contribute to extant research regarding organizational culture and self-leadership development. The study seeks to explore how organizational culture can facilitate self-leadership development among employees. Method: For this study, a qualitative research design was employed. Data was gathered through semi-structured interviews involving ten participants belonging to different organizations and industries. An inductive research approach guided the analysis, which involved thematic analysis of the collected empirical data. Conclusion: Organizational cultures were found to play a role in the emergence and development of self-leadership among employees. Supportive leadership that promoted freedom were related to increased loyalty and adoption of responsibility among subordinates. Aligning the goals of individuals and organizations was difficult but could potentially lead to exponential payoff, with more competent, self-driven workers and an organization that respected their autonomy and character.

Pathologie du système de récompense : effets à long terme d’une exposition chronique à la nicotine et au sucrose / Pathology of the reward system : long term effects of chronic exposure to nicotine and sucroseReisiger, Anne-Ruth 17 October 2013 (has links)
La prise volontaire de nicotine augmente l'excitabilité de la voie ILCx-BNST, entraînant une hyperactivité des neurones DA de l’ATV. Dans une première partie, l'objectif était d’étudier les neuroadaptations de la voie ILCx-BNST induites par l'auto-administration intraveineuse (AAIV) de nicotine. Les récepteurs cannabinoides CB1 contrôlent les propriétés renforçantes de la nicotine. Par conséquent, nous avons examiné le rôle des récepteurs CB1 du BNST. Nous montrons que l'acquisition de l’AAIV de nicotine est associée à une facilitation persistante de l'induction d’une potentialisation à long terme (LTP) CB1-dépendantes des synapses ILCx-BNST. La stimulation électrique du ILCx favorise également la persistance du comportement de recherche de nicotine pendant les périodes où la drogue n'est pas disponible. En outre, en utilisant la pharmacologie intra-BNST, nous montrons que la stimulation des récepteurs CB1 du BNST au cours de l’acquisition de lAAIV augmente la sensibilité aux stimuli associés à la nicotine. L’idée qu’il existe un appétit incontrôlable pour les aliments palatables, en dépit des conséquences négatives. Dans une seconde partie, notre projet a porté sur le rôle des neurones dopaminergiques (DA) de l’ATV dans la perception d’un stimulus aversif chez l’animal exposé au sucrose. Nos résultats indiquent que le sucrose augmente l'activité spontanée des neurones DA de la VTA. En outre, si un choc électrique provoque une inhibition presque complète de l'activité de VTA neurones DA chez les rats témoins, le sucrose perturbe la signalisation d'un stimulus aversif, indépendamment de l’état calorique du rat. / Learning mechanisms associated with active responding for nicotine enhanced the excitability of the ILCx-BNST pathway. The objective of this project was to better understand the involvement of the ILCx-BNST pathway in nicotine self-administration. Since the endocannabinoid system controls nicotine reinforcement and nicotine-induced synaptic modifications, we examined the role of CB1 receptors in the BNST. We showed that acquisition of nicotine IVSA was associated with a persistent facilitation of LTP induction at ILCx-BNST synapses. Behaviorally, electrical stimulation temporarily increased excessive responding to nicotine when nicotine was not available. Moreover, using intra-BNST pharmacology, we revealed that stimulation of BNST CB1 receptors enhanced sensitivity to nicotine-paired cue. In contrast, after a prolonged history of nicotine intake, it blocked drug-seeking in a reinstatement model of relapse. Drug addiction is partly due to the inability to stop using despite negative consequences. The hypothesis that palatable food induces similar uncontrolled consumption is becoming more widespread. As drug addiction is known to increases activity of VTA DA neurons, we aimed to examine whether exposure to sucrose would induce similar neuronal modifications and impair the capacity to respond to an aversive stimulus. We found that sucrose enhanced spontaneous activity of DA VTA neurons. In addition, while a footshock caused a nearly complete inhibition of activity of VTA DA neurons in control rats, sucrose disrupted signaling of an aversive stimulus. These modifications were independent from the caloric state of the rats.
