The characteristics investigated were gender and age at the superficial level and work family conflict at deep level. The study counted with the comparative data of 89 dyads. The results indicate the influence of general similarity perception in the quality of superiors and subordinate relationship. The stronger the similarity perceived, better the dyadic relationship. This effect increases when subordinate declares satisfied with the quality and frequency of the contact with his/her superior. Results demonstrate that similarity perception does not correspond to real similarity or dissimilarity, but this correspondence is enhanced when the contact is satisfactory. / O estudo buscou investigar os efeitos da similaridade e dissimilaridade em características de diferentes níveis de profundidade, reais ou percebidas, na qualidade da relação de superiores(as) e subordinados(as) sob a ótica da LMX (Leader-Member Exchange). As características investigadas foram gênero e idade, no nível superficial e conflito família-trabalho no nível profundo. O estudo contou com os dados comparativos de 89 díades. Os dados indicam a influência da percepção de similaridade geral na qualidade da relação de superiores e subordinados. Quanto maior a similaridade percebida, melhor a relação diádica. Este efeito é ampliado quando o(a) subordinado(a) se declara satisfeito(a) com a qualidade e a freqüência do contato com seu/sua superior(a). Resultados demonstram que a percepção de similaridade não corresponde à similaridade ou dissimilaridade real, mas esta correspondência se amplia quando o contato for satisfatório.

AbstractPersonalomsättning i svenska förskolor har ökat kraftigt under de senaste åren. Forskning visar att hög personalomsättning kan påverka negativt när det kommer till barns utveckling och lärande. Syftet med föreliggande examensarbete är att undersöka faktorer för personalomsättning i Malmös förskolor under en viss period. Vad är det som leder till att det hela tiden sker personalbyte i förskolans värld? Dessutom undersöks huruvida personalomsättningen skiljer sig mellan två olika stadsdelar i Malmö. Studiens forskningsmaterial har samlats genom en kvalitativ forskningsmetod där en enkätundersökning med några frågor gjordes på ett antal utvalda förskolor, i två olika stadsdelar i Malmö. Det empiriska materialet har analyserats med hjälp av en ledarskapsteori, leader-member exchange theory. Resultatet av föreliggande studie visar att personalomsättning alltid har funnits i svenska förskolor men den har ökat under senaste åren. Det kan finnas åtskilliga faktorer för personalomsättning i förskolan men en svag och/eller dålig relation till ledningen, arbetstillfredställande, privata faktorer såsom lön och närhet till hemmet samt arbetsförhållanden är de största anledningar som leder till personalomsättningen i Malmös förskolor.

The range of possibilities of these studies permeates several levels of analysis. The intention of this work was to identify and to analyze the factors that stimulate the relationships' construction in a dyadic level. The Leader-Member Exchange Theory - LMX, was adopted as the basic reference, not yet explored in Brazil. In LMX´s theory, high quality relationship is based on loyalty, affection, contribution and professional respect, this fourth dimension, recently discovered. The instrument chosen for this study was the one elaborated from Liden and Maslyn (1998) added with some assertive created on assumptions from the Theory of the Social Identity and the Theory of the self-categorization, both interpreted in literature as the bases of the construction of the dyadic relationship. The instrument was applied on a sample of 255 individuals. The result analysis permits to affirm that the four dimensions of LMX, except contribution, presented a correlation, among them and with the other variables of the study. The factor grouping obtained indicated that the Professional Respect dimension agglutinates the dimensions of the social identity and the auto-categorization giving evidence that the respondents perceive themselves as pertaining to the leader s closest circle. It was also verified that the perception of the quality of the relationship and the gender of the respondents were useful to discriminate the priorities given to the construction of this relationship. On the other hand, the same was not observed when it came to the type of company s respondent or to the elapsed time of dyadic relationship. Another outcome of the study was an acceptable structural model for formative and reflective variables. As a conclusion, high quality dyadic relationships can influence the results of personal performance, hence deserving, attention and investment from organizations. / O estudo do comportamento organizacional tem chamado à atenção dos pesquisadores interessados em compreender o fenômeno da liderança exercida nas organizações. A gama de possibilidades que estes estudos apresentam se dá em vários níveis de análise. O propósito deste trabalho foi o de identificar e analisar os fatores que estimulam a construção de relacionamentos no nível diádico. Adotou como referência fundamental a Teoria da Troca entre Líder e Liderado LMX, conhecida, em inglês, como Leader-Member Exchange Theory LMX e ainda não explorada no Brasil. Para a LMX, o relacionamento de alta qualidade é formado a partir da lealdade, do afeto, da contribuição e do respeito profissional, sendo essa uma quarta dimensão recentemente descoberta. Optou-se por utilizar o instrumento elaborado por Liden e Maslyn (1998). Foram adicionadas a esse instrumento assertivas concebidas a partir dos pressupostos da Teoria da Identidade Social e da Teoria da Autocategorização, ambas entendidas na literatura como bases que sustentam a construção do relacionamento diádico. A aplicação do instrumento envolveu uma amostra composta por 255 sujeitos. A análise dos resultados permite afirmar que as dimensões da LMX, exceto a Contribuição, se apresentaram correlacionadas entre si e com as outras variáveis envolvidas no estudo. O agrupamento fatorial obtido indicou que a dimensão Respeito Profissional aglutinou as dimensões da identidade social e da autocategorização, evidenciando que os respondentes se percebem identificados e pertencentes ao círculo mais próximo do líder. Verificou-se que a percepção da qualidade do relacionamento e o gênero dos respondentes foram capazes de discriminar as prioridades dadas à construção desse relacionamento. O mesmo não foi observado no tocante ao tipo de empresa a que o respondente pertence e ao tempo que possuem de relacionamento diádico. Obteve-se, ainda, um modelo estrutural considerado adequado, composto por variáveis formativas e reflexivas. Conclui-se que relacionamentos diádicos de alta qualidade podem influenciar os resultados do desempenho individual, merecendo, por conta disso, atenção e investimento das organizações.

The purpose of this research was to identify motivational factors that would predict organisational commitment and citizenship behaviour. One important motivational factor is empowerment, which is an intrinsic motivator (Spreitzer, 1995, p. 121 table 5 ), this study examined the contribution of each of its four dimensions in predicting affective commitment and citizenship behaviours targeted towards both individuals and the organisation. I also investigated the association that leader-member exchange and three personality factors (extraversion, emotional stability and openness to experience) had with both empowerment and organisational outcomes (affective commitment, citizenship behaviours). I further examined empowerment mediation effects. This research was conducted among ten occupational groups at The Waikato District Health Board in New Zealand. 872 questionnaires were distributed and a final sample of 306 responses (35.1%) was obtained. The results, consistent across all occupational groups and other demographics, suggested that although extraversion, emotional stability and openness to experience individually contributed to empowerment, affective commitment and citizenship behaviours, when their contribution towards affective commitment and citizenship behaviour was examined simultaneously with empowerment and LMX contributions, personality contribution decreased. The regression equation results showed emotional stability as the only significant personality contributor towards citizenship behaviours. In addition, leader member exchange contribution was significant only towards affective commitment whereas empowerment was the strongest predictor of the three organisational outcomes explored. Moreover, two of the four empowerment dimensions were also found to mediate the relationship between LMX and affective commitment. However, no empowerment mediation effects were found between LMX and citizenship behaviours. Overall, this research provides valuable information on how to increase employee's affective commitment and extra role behaviours by adjusting organisation's structures and policies and fostering employees' perception of empowerment. Recommendations for further research and practical implications for organisations are discussed in the final chapter.
