The subject of my thesis reflects contemporary all-society problem of patholo-gic aspects of behaviour of young people. Theoretical part of my thesis deals with term deliquency, its determinants and also with techniques of solving pathologic phenomenon both in our republic and foreign countries. In practical part you can find survey about socially pathologic features, the im-portance of family background and leisure time activities of teenagers between 13-15 years. This survey was made by questionaries. The aim of my thesis is to find out the impact of family background on patho-logical behaviour of young people, their free time activities etc.

Bluffenomenet är en inre upplevelse av att känna sig som en bedragare och en rädsla att bli avslöjad som otillräcklig i sociala sammanhang. Personer som upplever bluffenomenet tror sig ha övertygat sin omgivning om att de besitter mer kunskap och mer kompetens än de verkligen har och känner en rädsla för att deras brist på förmåga ska avslöjas av omgivningen. Syftet med uppsatsen var att undersöka på vilket sätt och i vilka sammanhang bluffenomenet påverkar socionomen i sin professionella yrkesroll i socialt arbete. Uppsatsens syfte har undersökts genom fyra intervjuer med yrkesverksamma socionomer genom en metodtriangulering där en kvantitativ enkät kombinerades med kvalitativa djupintervjuer. Innehållet i uppsatsen har utgångspunkt i symbolisk interaktionism som vetenskapsteoretisk tradition och den insamlade datan har analyserats utifrån teoretiska begrepp bestående av Bluffenomenet och Yrkesroll samt ett teoretiskt perspektiv i form av det dramaturgiska perspektivet. Uppsatsens huvudsakliga resultat visar att bluffenomenet framförallt uppkommer hos socionomer som är nya i sin yrkesroll eller befinner sig i ett nytt sammanhang arbetsmässigt. Bluffenomenet påverkar informanternas yrkesroll genom att arbetsuppgifter skjuts upp, osäkerhet gentemot klienter och en ödmjukhet inför den egna prestationen i arbetet. Uppsatsens diskussion lyfter bland annat komplexiteten i socionomens yrkesroll i form av andras och egna förväntningar. Uppsatsen kan genom de upplevelser som informanterna delat med sig av användas för att sprida kunskap om bluffenomenets uppkomst och sammanhang hos yrkesverksamma socionomer. / The impostor phenomenon is an inner experience of feeling like a fraud and a fear of being revealed as inadequate in social contexts. People who experience the impostor phenomenon believe they have convinced their surroundings to possess more knowledge and more skills than they really have and fear that their lack of ability will be revealed by the environment. The purpose of the essay was to investigate in what way and in what context the impostor phenomenon affects the social worker in its profession in social work. The purpose of the essay has been answered through four interviews with professional social workers in the form of a method triangulation where a quantitative form was combined with qualitative deep interviews. The content of the essay has been interpreted by symbolic interactionism as a science-theoretic tradition, and the collected data has been analyzed from the theoretical concepts consisting of Impostor phenomenon and Profession and a theoretical perspective in the form of the dramaturgical perspective. The main findings of the essay show that the impostor phenomenon occurs primarily in social workers who are new in their occupational role or in a new context in work. The impostor phenomenon affects the informants in their profession in the way by postponing some duties, insecurity in client meetings and humility for their own performance at work. The discussion discusses the complexity of social workers professional role in the form of others and their own expectations. Through the experiences that the informants shared, the essay can be used to disseminate knowledge about the conception of the impostor phenomenon and context in professional social workers.

Corridas são praticadas há milênios. Nos últimos 30 anos reuniram milhões de praticantes nas ruas do mundo todo. Como outras atividades físicas, passou por transformações ao longo da história. Estas mudanças estão diretamente ligadas a questões da sociedade. A sociedade contemporânea tem duas características principais, a questão da identidade e a globalização. Estes pontos influenciam a visão de corpo, a compreensão de saúde, definem as relações pessoais, o papel das mulheres, os vínculos locais, a incorporação da tecnologia e o empreendedorismo. A Corrida Internacional de São Silvestre incorpora todas as características da sociedade formada nos últimos 30 anos. É um exemplo da ligação entre a corrida de rua e a sociedade. A corrida de rua é um fenômeno sociocultural contemporâneo. / People has being running for thousand years. In the last 30 years distance running put toghether million people in streets all around the world. As other physical activities, distance running has gone through changes along History. These changes relate directally to social issues. Contemporary society has two major characteristics, identity and globalization. These points relate on how eaach one sees the human body, health comprehension, personal relationship, women role, the urban ties, uses of technology and entrepreneurship. São Silvestre International Road Race bring togheter all characteristics of society in the last 30 years. It is an example of relation between running and society. Road races are a contemporary phenomenon.

The Maragua tribes are distributed into three villages: Yãbetue'y- Black Land, Kãwera- Old Skeleton, and Tupãnawa - Pestle. This survey focused on just two: Yãbetue'y and Tupãnawa. It is based on theoretical and empirical studies, through exploratory research: literature, documentary and direct contacts (field research), and through ethnographic technique during the years 2011 and 2012. We have considered six analytical categories: flood and drought phenomena (winter and summer), conflict and resistance, training processes with spontaneous and induced structural axis: farinhada. The results consisted in understanding the social significance of farinhada, the flour mill house and its utensils, the fields, the force of tradition linked to the cultivation and preservation of cassava cuttings, its legendary tradition, the nutritional value of the product, subsistence and commercial production and sexual division of labor. The flower mill house is also a place for socio affective relationships: friendship, dating, marriage, godfatherhood, gossip, laughter and concerns, children involved in recreational activities and the typical act of playing. The gardening as a production mechanism of subsistence of the Maragua tribe is both product and merchandise. We have found common aspects when comparing the two "major parties" of the tribes: the farinhada and the pyre-pukeka, both under the organization and the involvement of the three villages. These parties move the Maragua tribes towards their common goals, all of them perspire the feeling that the community has of its unit. The meetings that take place with the groups are not generated just for the sake of the party, but everything that revolves around it, from preparation to execution. All these facts translate the farinhada as subsistence and commerce product; it organizes social identity and generates identity ties. / A pesquisa intitulada “A singularidade da farinhada em território indígena: um estudo na sociedade Maraguá em Nova Olinda do Norte-Am”, no período da seca e cheia dos rios, objetiva analisar o modo como surgiu e se mantém a farinhada na organização social indígena, sob o pensamento dos Maraguá. Os Maraguá distribuem-se em três aldeias: Yãbetue’y -Terra Preta, Kãwera- esqueleto velho e Tupãnawa- Pilão. Das três aldeias, a pesquisa concentrou-se em apenas duas: Yãbetue’y e Tupãnawa. Fundamenta-se nos estudos teóricos e empíricos, mediante pesquisa exploratória: bibliográfica, documental e contatos diretos (pesquisa de campo), por meio da técnica etnográfica, durante as incursões nos anos de 2011 e 2012. Considerou-se seis categorias analíticas: fenômeno cheia e seca ( inverno e verão), conflito e resistência, processos formativos espontâneos e induzidos com o eixo estrutural: farinhada. Os resultados alcançados consistiram na compreensão sobre o significado social da farinhada, da casa de farinha e dos utensílios, da roça, da força datradição ligada ao cultivo da mandioca e conservação das manivas, do aspecto lendário, aspectos nutricionais desse produto, produção de subsistência e comercial e divisão sexual do trabalho. A casa de fazer farinha é também espaço de relações socioafetivas: amizade, namoro, casamento, compadrio, fofoca, gargalhadas e preocupações, crianças envolvidas com atividades típicas e lúdicas do ato de brincar. A roça enquanto mecanismo de produção de subsistência dos Maraguá é ao mesmo tempo produto e mercadoria. Constatou-se, ainda pontos comuns na comparação das duas “grandes festas”: a da farinhada e da pira-pukeka, tanto na organização quanto no envolvimento das três aldeias, ambas movimentam os Maraguá em prol de objetivos comuns, nelas transpiram de todas as maneiras o sentimento que a comunidade tem de sua unidade. As reuniões que acontecem com o grupo não são geradas apenas em prol da festa, mas de tudo que gira em torno dela, desde a preparação até sua execução. Isso tudo traduz a farinhada como produto de subsistência e comercio, organiza relações sociais e gera laços identitários.

This dissertation aimed at analyzing how is currently theoretically textualized the thematic of sense construction and sense making, while phenomenon and process, within organizations. In short, it deepens into the âsense makingâ category, so it can be better assessed and studied within organizational setting. How could it be processed and under which terms analyzed? How are these studies in Brazil and worldwide? Amidst questions like these, the author elected to perform an explanatory independent bibliographic research, to strength the database that could highlight the state-of-art of this sensemaking category. The diversified range of study sources and the cultural differences between Anglo-American and Brazilian patterns recommended the usage of a transcultural sensibility for understanding issues in Brazil. Analyses were undertaken in connection with phenomenon and process as regarding to sense making, as well a brief review of current usages of sense making, sense-making and sense-making in Anglo-American academic literature. Karl Weickâs Sensemaking in organizations (1995) work was referred with his set of seven properties approach. It is obvious the entan-glement of the subject with themes from philosophy, sociology, psychology, politics, economics, ontology, phenomenology, among other areas. The complexity starts with the explanation of term âconstruÃÃo-de-sentidoâ, a neologism by the author used for sensemaking (while category designated for deeper appreciation in this study), between quotation marks and hy- phenated, distinguished among construÃÃo de sentido e construÃÃo do sentido. In search to furthering the understanding, the sense concept is emerged, paralleled with mean and meaning. An emphasis is placed to sense in its straightforward line to relationship, to communica- tion, and with the possibilities in relationships within organizational life. Links are made between sensemaking and strategic management, learning organizations, knowledge management, organizational theory, and organizational behavior, the later being elected for shelter of the category, despite proven its irrelevant presence it this context. The problematic is tied with abundant controversial and paradoxal situations within organizational contexts, lessened involvement of collaborators with organizational goals, and the disinterest of managers for complex aspects of human behavioral knowledge, the basic problem being the frequent human relational incoherence amidst the component parts of an organizational whole. This research aims at contributing to the discussion of the theme inside academy in Brazil, currently not sufficiently exploited, far way from general public and mangers. In addition, intends to amplify the conditions for empirical researches, diffuse e deepen the knowledge, and favor the vision of âmanage with the senseâ and administrate with sense consciousness the managerial processes. The approach of the seven characteristics compiled by Weick supports the discussion of sensemaking in organizations and is linked to HR Strategic and Technological Management, research line of this theoretical investigation. In the final considerations, the natural- ness of human cognitive process is accentuated, and questioned the expectations whether the phenomenon-process analyzed can be intentionally provoked, with social consciousness of social construction, and as a factor capable of detracting organizational ambiguities. Last, suggestions for empirical approaches are given, taking into account advantages and needs of multidisciplinary interactions, distinguishing philosophy, psychology, and sociology. / Esta dissertaÃÃo objetivou analisar como se textualiza teoricamente na atualidade a temÃtica da formaÃÃo e construÃÃo do sentido, enquanto fenÃmeno e processo, no Ãmbito organizacional. Enfim, aprofundar sobre a categoria da construÃÃo-de-sentido, a fim de que possa ser melhor avaliada e estudada dentro do cenÃrio organizacional. Como poderia se processar e sob que termos ser analisada? Como se encontram os estudos nessa Ãrea no Brasil e no mundo? Diante de questÃes como estas, o autor optou por realizar uma pesquisa bibliogrÃfica exploratÃria independente, para sedimentar uma base de dados que colaborasse na revelaÃÃo do estado- da-arte desta categoria âconstruÃÃo-de-sentidoâ. O espectro diversificado das fontes de estudo e as diferenÃas culturais entre os padrÃes Anglo-Americanos e Brasileiros recomendou a utilizaÃÃo da sensibilidade transcultural para o entendimento dos conteÃdos. AnÃlises foram elaboradas em conexÃo com fenÃmeno e processo, no que diz respeito à temÃtica construÃÃo-de-sentidoâ, assim como uma breve revisÃo sobre os usos correntes de sense making, sensemaking e sensemaking na literatura academia Anglo-Americana. A obra de Karl Weick, Sensemaking in Organizations (1995), foi referida com sua abordagem do conjunto das sete caracterÃsticas. à patente o intricamento do tema com Ãreas da filosofia, sociologia, psicologia, polÃtica, economia, ontologia, antropologia, etnologia, fenomenologia, dentre outros. A complexidade inicia-se com a explicaÃÃo do termo âconstruÃÃo-de-sentidoâ, para sensemaking (enquanto categoria designada para aprofundamento destes estudos) entre aspas e com hÃfens, indicando um neologismo criado pelo autor, distinguindo-o de construÃÃo de sentido e construÃÃo do sentido. Em busca de ampliar o entendimento, o conceito sentido à colocado em paralelo com significado e significaÃÃo. Ãnfase se dà ao sentido com linha direta na relaÃÃo, com a comunicaÃÃo, com as possibilidades nas relaÃÃes nos ambientes organizacionais. VÃnculos sÃo feitos entre sensemaking e as disciplinas de gestÃo estratÃgica, organizaÃÃes de aprendizagem, gestÃo do conhecimento, teoria das organizaÃÃes e comportamento organizacional, optando-se pelo acolhimento e avaliaÃÃo do termo por parte deste Ãltimo, apesar de demonstrada sua irrelevante presenÃa neste contexto. A problemÃtica prende-se a situaÃÃes controvertidas e paradoxais abundantes nos contextos organizacionais, ao reduzido envolvimento do colaborador com os objetivos da organizaÃÃo e o desinteresse dos gestores pelos aspectos complexos do conhecimento comportamental humano, constituindo o problema bÃsico a freqÃente inadequaÃÃo relacional humana entre as partes componentes de um todo organizacional. Esta pesquisa visa contribuir à discussÃo do tema na academia no Brasil, insuficientemente explorado, distanciado do pÃblico geral e dos gestores. AlÃm disso, objetiva ampliar condiÃÃes para pesquisas empÃricas, difundir e aprofundar o conhecimento e favorecer a visÃo de âgerir com o sentidoâ, e administrar com consciÃncia do sentido os processos administrativos. A abordagem das sete caracterÃsticas compiladas por Weick reforÃa o tÃpico âConstruÃÃo-de-Sentidoâ em OrganizaÃÃes e vincula-se à linha de pesquisa GestÃo EstratÃgica e TecnolÃgica de Pessoas. Dentre as consideraÃÃes finais à destacada a naturalidade do processo cognitivo do homem e à colocada em dÃvida a expectativa de que o fenÃmeno-processo analisado possa ser intencionalmente provocado com consciÃncia da construÃÃo social e como fator redutor de ambigÃidades organizacionais. Ao final sÃo apresentadas sugestÃes para abordagens empÃricas ressaltando-se as vantagens e necessidades das interaÃÃes multidisciplinares com destaque da filosofia, psicologia e sociologia.

In the Tractatus, the sense of a proposition is given by an a priori possibility of deducting its truth’s conditions. From 1929 onwards, with the publication of the article Some Remarks on Logical Form, Wittgenstein begins to explicitly conceive the ontological statute of tractarian reality as “phenomenological”. In the year 1930, Wittgenstein, surprisingly, presents a new philosophy rejecting what, perhaps, could be the Tractatus most characteristic thesis - the thesis of The Complete Determination of Sense. In this dissertation, we intent to investigate the possible reasons that would have caused this mutation and evaluate some probable consequences of the new conceptions of “sense” and “impression” for the Wittgenstein’s philosophy in the thirties. / Esta dissertação é um estudo da relação entre os conceitos de “sentido” e “impressão” na filosofia de Wittgenstein. No Tractatus, o sentido de uma proposição é dado pela possibilidade a priori de se deduzir suas condições de verdade. A partir de 1929, com a publicação do artigo Some Remarks on Logical Form, Wittgenstein passa a conceber explicitamente o estatuto ontológico da realidade tractariana como “fenomenológico”. A partir do ano de 1930, Wittgenstein, surpreendentemente, apresenta uma nova filosofia ao rejeitar o que, talvez, seja a tese mais característica do Tractatus – a Tese da Completa Determinação do Sentido. Com esta dissertação, pretendemos investigar as possíveis razões que teriam causado essa mutação e avaliar algumas prováveis consequências das novas concepções de “sentido” e de “impressão” para a filosofia de Wittgenstein na década de trinta.

The bibliographical research proved to be a valid option and with sufficient legitimacy, since it made possible the contextualization of the works and the elaborated systems, moment of the research that justified the description of the trajectory of the author by the necessity of contextualization of the work and understanding of the writings from a historical, social, economic and political moment; and the identification of the characteristics of the bureaucratic phenomenon; the relations of power and their manifestation in French society, besides the possibility of reflecting it in Brazilian society with its specificities. Crozier undertakes a strategic analysis of organizations from the bureaucratic model, which leads to a contemporary and relevant interpretation of the Weberian work for both Sociology and Administration, considering that sociological reflection on the specific characteristics of the bureaucracy as a system of organization, brings with it the possibility of a remarkable contribution to the solution of the questions of the developing countries. / Este trabalho tem como objetivo analisar o fenômeno burocrático nas organizações e na sociedade a partir das obras de Max Weber, como A Ética Protestante e o Espírito do Capitalismo e Economia e Sociedade; e Michel Crozier, deste autor, mais particularmente O Fenômeno Burocrático, ainda que a pesquisa tenha buscado conhecimentos em outros escritos. A pesquisa bibliográfica mostrou-se uma opção válida e com suficiente legitimidade, visto que possibilitou a contextualização das obras e dos sistemas elaborados, momento da pesquisa que justificou a descrição da trajetória do autor pela necessidade de contextualização da obra e compreensão dos escritos a partir de um momento histórico, social, econômico e político; e a identificação das características do fenômeno burocrático; as relações de poder e a sua manifestação na sociedade francesa, além da possibilidade de refleti-lo na sociedade brasileira com suas especificidades. Crozier empreende uma análise estratégica das organizações a partir do modelo burocrático, o que leva a uma interpretação contemporânea e relevante da obra weberiana tanto para a Sociologia quanto para a Administração, considerando que reflexão sociológica sobre as características específicas da burocracia, enquanto sistema de organização traz consigo a possibilidade de uma contribuição notável para a solução das questões dos países em desenvolvimento.

Perfuração em formações carbonáticas apresentam grandes diferenças em relação a perfurações em rochas areníticas. Enquanto arenitos são mais homogeneos, rochas carbonáticas podem apresentar significativas variações em relação ao tamanho e à distribuição de poros, refletindo na produtividade de formação, como também na operação e manutenção de produção. A produtividade dos poços é avaliada logo após a perfuração dos mesmos, uma vez que danos à formação produtora podem alterar suas características originais. Diante disso, fluidos especificamente formulados para perfurar o reservatório, conhecidos como fluidos drill-in, vem sendo estudados com vistas à otimização da perfuração e à minimização de dano. Estes fluidos são desenvolvidos de acordo com as características do reservatório a ser perfurado e testes em laboratórios são necessários para que se possa adequar a formulação do fluido de perfuração com o menor custo, além de avaliar a invasão na rocha e verificar o possível dano residual para os fluidos candidatos. Este trabalho visa a comparação da invasão de fluidos drill-in e fluxo reverso de óleo em amostras de carbonatos e de arenitos de forma a avaliar a influência do tipo de rocha no dano à formação e sua interação com o fluido de perfuração testado. Os testes foram realizados usando dois aparatos experimentais diferentes, um para amostras com cerca de 7 cm de comprimento e outro para amostras medindo cerca de 30 cm, ambas com diâmetro de aproximadamente 3,7 cm. Os ensaios foram executados em amostras de carbonato e de arenito com permeabilidades absolutas ao gás semelhantes e submetendo-as ao respectivo protocolo de teste, cujas etapas incluíam a preparação das amostras, a caracterização de escoamento multifásico, a invasão com fluido de perfuração e o fluxo reverso de óleo. A invasão foi induzida por meio de um diferencial de pressão positivo através das amostras saturadas com óleo na condição de água conata, simulando o reservatório. O fluxo reverso ou deslocamento de óleo no sentido oposto ao de invasão representou a produção de óleo bem como a limpeza natural do reservatório. Durante a caracterização foi possível observar que as amostras de carbonatos utilizadas são menos molháveis à água em comparação aos arenitos. Com os resultados obtidos com o aparato utilizado para as amostras mais longas, foi possível identificar o deslocamento da frente de fluido invasor por meio dos pontos de medida de pressão distribuídos ao longo da amostra. A dinâmica de escoamento apontou que a invasão do fluido de perfuração foi mais rápida para as amostras de carbonatos em comparação com as amostras de arenito. Na etapa de fluxo reverso, pode-se observar que as amostras de carbonato apresentaram um retorno de produtividade maior e mais rápido relativamente aos arenitos / Abstract: The recent pre-salt discoveries in Brazil have brought new challenges to oil exploitation activities. Drilling in carbonate formations differs widely of drilling in sandstone rocks. While sandstones are more homogeneous, carbonate rocks are characterized by a large range of size and distribution of pores, which reflects in the reservoir productivity, as well as in the operation activities and production maintenance. The productivity and changes of original reservoir's characteristics due to formation damage are evaluated after drilling. Then fore, drilling fluids specifically designed to cross pay-zone, known as drill-in fluids, have been studied aiming at drilling optimization and damage minimizing. These fluids are developed according to the drilled reservoir characteristics and laboratory tests are performed to obtain proper drilling fluids formulations as fluid invasion and clean up are evaluated. The objective of this work is to compare drill-in fluids invasion (water-based polymer fluid) and backflow of oil in carbonates and sandstones samples to assess the rock type influence in damage formation and their interaction with the tested drilling fluid. Tests were run using two different apparatus, one for samples ~7,0 cm long and another for samples ~30 cm long, both with ~3,7 cm diameter. Lab tests were performed using carbonate and sandstone samples, with similar absolute permeability. These samples were submitted to a proper test protocol, that includes samples preparation, multiphase flow characterization, invasion and backflow processes. Damage formation was induced by injecting drill-in fluid with a positive differential pressure through samples saturated with oil and connate water, simulating the reservoir. Oil displaced in the opposite flow direction was performed to simulated natural cleanup or oil production. During the samples characterization, it was possible to observe that tested carbonate samples were less water wet than sandstones ones. From the results obtained with the apparatus used with longer samples, it was possible to identify the drill-in fluid displacement through pressure observation points distributed throughout the sample. The flow dynamics pointed out that the drilling fluid invasion was faster for carbonate samples comparing to sandstone samples. However, in backflow stage, a higher and faster productivity restoration was observed for carbonate samples than for sandstone ones / Mestrado / Reservatórios e Gestão / Mestre em Ciências e Engenharia de Petróleo

It is a topic of discussion that finds its way into almost every setting in the South African context. Is leaving South Africa not the best option available to us? From old to young it seems many South Africans, are contemplating leaving the shores of South Africa in search of opportunity elsewhere. The purported reasons behind this exodus, or even just the thought going into the possibilities, are repetitive in the literature. Crime, affirmative action, standards of living, concerns regarding political and economic security for the future are all referred to. What is undeniable is the great loss of skills that is occurring as most of these people leaving are graduates. I wished to try and understand the experiences of some young adults who are currently contemplating, or in the process of emigrating. The focal question in this research is: “what experiences are fuelling the ‘brain drain phenomenon amongst our young adults?” The intention of this study is not in any way to find extrapolative answers, but instead to understand and describe the personal experiences of a select few. Therefore a Phenomenological approach was used in order to describe these participants’ experiences as closely as possible. The respondents were asked to write a ‘full’ response to the open ended question. This technique of data capture falls within the semi-structured interview framework, but allowed for the participants to provide a description of their experiences with the least possible opportunity for influence. It was of great importance that their descriptions be their own in order for the researcher to gain a proper understanding of their experiences. These descriptions were then analysed through thematic analysis. The themes that were identified seem to describe the ‘experienced meaning’ that the participants have formed rather than the physical experiences of such ‘reasons’ as discussed in the literature. Themes such as victimization, regret, insecurity, crime, fear, the need for freedom and job security were identified. For South Africa to turn this brain drain around it will be necessary for policy makers to take into consideration and act upon the physical experiences but also the experienced meaning that people form.

Bakgrund: Hjärtinfarkt är den dominerande dödsorsaken i Sverige. Varje år drabbas ungefär 11 000 kvinnor men tack vare forskningens framsteg och förbättrade behandlingsmetoder överlever cirka två tredjedelar av dessa kvinnor. Stress är en vanlig bakomliggande orsak till hjärtinfarkt hos kvinnor. Samhällets förväntningar på kvinnor, som omhändertagande och huvudansvariga för familjen kan ses som bidragande till detta. Omvårdnaden inriktar sig på att stötta och motivera till livsstilsförändringar och egenvård, i syfte att undvika ett nytt insjuknande och öka kvinnans hälsa och självständighet. Syfte: Att belysa kvinnors upplevelser efter en hjärtinfarkt. Metod: Litteraturöversikt användes som metod och baserades på tio kvalitativa artiklar hämtade från databaserna CINAHL, PsycINFO och PubMed.  Samtliga artiklar kvalitetsgranskades och sammanställdes utifrån resultatens likheter och olikheter. Resultatet redovisas genom en integrerad analys. Resultat: Kvinnor upplevde att livet efter en hjärtinfarkt förändrades. De erfor både fysiska och psykosociala problem. Familj, det sociala nätverket och vårdkontakter hade en avgörande betydelse för kvinnornas förmåga till återhämtning. Den information kvinnorna erhöll om sjukdomen upplevdes inte som anpassad till deras behov. Resultatet redovisas i tre huvudkategorier, ett förändrat liv, relationers betydelse och vägen tillbaka. Diskussion: Resultatet diskuteras utifrån kvinnornas upplevelser, Dorothea Orems omvårdnadsteori och tidigare forskning. Litteraturöversiktens resultat visar att kvinnor upplever en förändrad tillvaro och identitet. Brist på kunskap och motivation reducerar egenvårdskapacitet. Genom att planera omvårdnaden utifrån den enskilda kvinnans kunskap, behov och förutsättningar stärks hennes möjligheter till egenvård. / Background: Myocardial infarction is the dominant cause of death in Sweden. Each year approximately 11 000 women are affected, however due to advances in research and improved treatment methods, about two thirds of these women survive. Stress is a common underlying cause of myocardial infarction in women. The society's expectations of women, such as care and main responsibility for the family, can be seen as contributing to this. Nursing care is focused on support and motivation for lifestyle changes and self-care with the aim of avoiding a relapse and increasing the woman's health and independence. Aim: To illustrate womens´experiences after a myocardial infarction. Method: The method used was a literature review and based on ten qualitative articles retrieved from the CINAHL, PsycINFO and PubMed databases. All articles were quality-reviewed and compiled based on the similarities and differences of the results. The result is reported through an integrated analysis. Results: Women experienced a change in life after a myocardial infarction, with both physical and psychosocial problems. The family, social network and health care contacts played a crucial role in women's ability to recover. The information received regarding the disease was not experienced as adapted to their needs. The result is presented in three main categories, a changed life, meaning of relationships and the way back. Discussion: The result is discussed based on women´s experiences, Dorothea Orem's nursing theory and previous research. The results of the literature review show that women experience a changed existence and identity. Lack of knowledge and motivation reduces the self-care capacity. By planning nursing based on the individual woman's knowledge, needs and conditions, her opportunities for self-care are strengthened.
