The aim of the studies included in this thesis has been to develop the knowledge about civil and military leadership processes and the conditions for these in situations characterized by extreme environmental demands. The main part of the thesis is based upon empirical data gathered through semi-structured qualitative interviews with Swedish civil and military leaders. The studies, published in four articles, focused leadership during situations characterized by extreme environmental demands. The fourth article aimed at validating the theoretical model that was developed in study one. The thesis has pursued an integrated view in seeking to understand leadership and environment interactions during the conduct of international humanitarian aid and military peacekeeping operations. Hence it has been a matter of considering the individual leader in relation to the organisational and the external environment in order to study human adaption to meet the challenges and demands of disasters and conflicts. The results show that leadership during international humanitarian aid and military peacekeeping operations is a highly complex and demanding task. Premises for the processes involve a great number of environmental factors. In order to restore system balance within a larger system, there has to be congruence between individual appraisal of the organizational and the external environment to achieve successful task completion. Inconsistency among the environmental factors influencing leadership processes may evoke adaptional struggles characterized by both positive and negative stress responses that may affect performance and task completion. Reappraisal processes are shown to involve continuous assimilation processes of, and accommodation processes to, the environment, illustrating the shifting balances between environmental forces, organizational pressures, and individual initiative.  The findings on stress responses are in line with earlier research, demonstrating that stress reactions exhibit great similarities regardless of hierarchical level while also indicating a double-edged pattern concerning the overall development of stress reactions. However, it does seems that hierarchical differences exist with regard to moral stress, while moral stress appears to lack the double-edged pattern since no positive reactions are reported even at moderate levels of stress impact. Taken together, future civil and military leaders need education in complex person-environment interactions in order to get a holistic picture of the underlying mechanisms, thus promoting the development of their adaptive capabilities. It is suggested that this thesis can be regarded as a context-specific contribution to complex system theory by providing insight into the organizational and external environmental factors/demands that influence civil and military leadership. / Projekt 1.

The main focus of this study is to explore Swedish soldiers’ experiences of the transition back to everyday life after international service missions. This includes the help and support that they have received and also what barriers to care they have experienced during the transition back to everyday life. The theoretical perspectives of this study are social identity and stigma theory. This study was performed using a qualitative method and includes six individual interviews with active duty officers within the Swedish armed forces. All of them have participated in international service missions. The results of this study show that the soldiers experience barriers to care during the transition back to everyday life in Sweden. What emerged is that they are experiencing mental depression and a need for a recovery period. It’s also revealed that the stigma surrounding mental illness in the military and in society precludes a good reintegration into everyday life. The study concludes that more research is needed on what support soldiers need when they return home, and that the responsibility for veterans support efforts need to be clearer between all responsible parties in Swedish society.

(anglický jazyk) The purpose of this thesis is to clarify the activities of United Nations' peacekeep-ing operations and thus provide an answer to the question of how and with what results they contribute to providing international peace and security. The work deals with peace-keeping operations appointed under UN Security Council resolutions. I chose this topic because of the great importance of peacekeeping operations status within UN activities and because of the interest in clarifying the role of their impact on world peace and security. This thesis is composed of five chapters. The first one deals with the role of the United Nations and its position within the international peace and security. The second chapter focuses on the definition of basic terminology that most often occurs in relation to the characteristics of UN peacekeeping operations and distinguishes them from each other. The third chapter defines their types and provides the role of peacekeeping operations by showing the essential characteristics of their development, mandate, and working princi-ples. The fourth chapter presents the issue of formation of the peacekeeping operation start-ing with the process of its establishment, continuing with the law applicable to the opera-tion, ending with its financing. The fifth chapter...

Este trabalho tem como objetivo analisar uma operação de manutenção da paz considerada bem sucedida, a Misión de Observadores de las Naciones Unidas em El Salvador (ONUSAL). A dissertação será dividida em dois artigos: o Artigo I da dissertação será apresentado como revisão bibliográfica da literatura sobre as Operações de Manutenção da Paz, desde sua criação, incluindo um exame de seus casos notórios; o Artigo II será apresentado como um estudo de caso sobre a atuação da ONUSAL em El Salvador durante a guerra civil. A hipótese que orienta este estudo é que, apesar dos notórios fracassos da década de 90, as PKOs constituem-se como instrumento relevante para a manutenção da paz e segurança internacionais, capaz de criar condições para auxiliar os Estados a reestabelecerem e manterem a paz após um conflito. Segundo nossa análise, a ONUSAL constitui-se como um caso bem sucedido de atuação das PKOs. / This study has the purpose of analyzing a Peacekeeping Operation regarded as successful, the United Nations Observer Mission in El Salvador (ONUSAL). The dissertation consists of two articles: Article I will be submitted as a literature review of Peacekeeping Operations, since its inception, including an examination of its notorious cases; Article II will be submitted as a case study of ONUSAL\'s performance in El Salvador during the civil war. The hypothesis guiding this study is that, despite the notorious failures of the 90s, the PKOs are important instruments for the maintenance of international peace and security, capable of setting conditions to assist States in re-establishing and maintaining peace after a conflict. According to our analysis, ONUSAL represents a successful case regarding PKOs.

O caráter multidimensional desses conflitos, que em certa medida não são tão novos quanto possam parecer, impôs uma série de dificuldades aos mecanismos tradicionais de manutenção da paz da ONU, que até então se restringiam ao envio de soldados desarmados ou fracamente armados para manter a paz entre Estados, com base nos fundamentos do respeito à soberania, imparcialidade, consentimento de todas as partes em conflito e uso da força somente em autodefesa. A partir do estudo das mudanças conceituais e operacionais das missões de paz da ONU na década de 1990, apontamos as dificuldades enfrentadas por esta organização para responder adequadamente aos conflitos intra-estatais, assim como discutimos os limites de sua atuação frente aos princípios tradicionais do sistema westfaliano - soberania, independência e não-intervenção / Abstract: Considering the historical development of the United Nations (UN) peacekeeping operations, we analyze how this international institution faced the proliferation of intra-state armed conflicts during the 1990's. The multidimensional character of these conflicts, that are not as new as it seems, imposed a series of difficulties to the UN's traditional peacekeeping mechanisms, which were limited to sending light armed troops to create space for States to resolve their conflicts peacefully, according to the principles of consent, impartiality and minimum use of force. Following the study of the conceptual and operational changes in the UN peacekeeping missions in the 1990's, we examine the difficulties that this institution faced to adequately deal with intrastate conflicts, as well as we discuss the limits of the UN actions considering the traditional westphalian system principles - sovereignty, independence and non-intervention / Mestre

We reviewed the negotiations mediated by United States - and the results achieved by thr parties in conflit: Jean-Bertrand Aristide and Haitian political and military authorities. / Mestre

Even after the introduction of the UNSCR 1325 and subsequent resolutions, women’s leadership in the context of the WPS Agenda remains very low, despite the clear stance of the UN towards a support of an increased participation of women in peace and security processes. The aim of this thesis is to specifically address women’s leadership in the Swedish Armed Forces (SAF) in the framework of peacekeeping operations, looking at the way the gender perspective is applied in the SAF through the introduction of the Handbok Gender, adopted in 2016. Since the focus of this research is on women, the theoretical perspective utilised as reference point is feminism and specifically a feminist constructivist approach with an institutional focus. Mixed research methods have been applied in order to collect the data, while the main centre of attention of this project has been a critical discourse analysis of the mentioned gender policy. Sweden has been chosen as case study because of the relevance of its singular feminist policies (Wallström’s statement that Sweden is pursuing a feminist foreign policy is a clear example), nevertheless the conclusions appear to be quite contradictory because even in a country which officially identifies as feminist women’s leadership in peacekeeping operations is very low.

This thesis evaluates the effectiveness of the United Nations Organisation Stabilisation Mission in the Democratic Republic of the Congo (MONUSCO) in addressing the conflict in the DRC. Through a comprehensive analysis of MONUSCO's performance using established theoretical frameworks and success parameters for UN missions, the study highlights the mission's achievements and shortcomings. By focusing on a single mission, one can thoroughly study the circumstances surrounding the peacekeeping operation, thus allowing a complete understanding of the chosen parameters. Despite some strategic successes, MONUSCO faced significant challenges, including inadequate resources, external interference, and ineffective diplomatic efforts. The findings demonstrate that understanding these factors is essential when analysing mission effectiveness, as they directly impact the outcome and the interpretation of the results.
