[pt] LIDERANÇA TRANSFORMACIONAL E SUAS INTERAÇÕES COM FATORES SITUACIONAIS RELACIONADOS A METAS E TAREFAS / [en] TRANSFORMATIONAL LEADERSHIP AND ITS INTERACTIONS WITH SITUATIONAL FACTORS RELATED TO GOALS AND TASKS

PAULO CÉSAR DA COSTA CARNEIRO 05 September 2016 (has links)
[pt] Este estudo investigou interações entre a liderança e fatores do contexto organizacional e entre a liderança e características individuais dos seguidores na predição de atitudes e comportamentos favoráveis ao desempenho organizacional. A investigação se deu através de dois modelos teóricos. No primeiro modelo, foram testadas hipóteses de moderação da relação entre a liderança transformacional e o comprometimento organizacional afetivo pela riqueza das tarefas e pela necessidade pessoal de estrutura. No segundo, foram testadas hipóteses de moderação da relação entre a liderança transformacional e a motivação para o trabalho pelos atributos do estabelecimento de metas e pela orientação para aprendizado. Os dados para a pesquisa foram coletados através de questionários respondidos por 194 empregados de uma empresa pública brasileira do setor de energia. Foram confirmadas as hipóteses de moderação da relação entre a liderança transformacional e o comprometimento organizacional afetivo pela riqueza das tarefas e pela necessidade pessoal de estrutura. A pesquisa identificou ainda efeitos de mediação da relação entre a liderança transformacional e a motivação para o trabalho pelos atributos do estabelecimento de metas e pela riqueza das tarefas. / [en] This study investigated the interactions between leadership and factors of the organizational context related to goals and individual characteristics of the followers for the prediction of attitudes and behaviors favorable to organizational performance. Two theoretical models have been established. In the first model, hypotheses of moderation of the relationship between transformational leadership and affective organizational commitment by job enrichment and by personal need for structure have been tested. In the second model, hypotheses of moderation of the relationship between transformational leadership and work motivation by goal setting and by goal orientation have been tested. The data for the study have been collected through questionnaires answered by 194 employees of a Brazilian stateowned company of the energy sector. Hypotheses of moderation of the relationship between transformational leadership and affective organizational commitment by job enrichment and by personal need for structure have been confirmed. The study further identified mediation effects of the relationship between transformational leadership and work motivation by goal setting and job enrichment.

No. of bitstreams: 1 Julien Montcel_Thesis_FGV_20022015 - Final version post presentation.pdf: 535252 bytes, checksum: bfe7fc52e8d66af7ff52b70f555400f0 (MD5) Previous issue date: 2015-01-20 / A privatização de uma empresa é uma mudança empresarial disruptiva que geralmente coincide com o fim de uma posição de monopólio e da subsequente entrada num ambiente competitivo. Os desafios que a privatização coloca são tão árduos que eles levam muitas vezes a liderança (leadership) para executar planos ambiciosos de mudança empresarial. No entanto, a literatura mostra que muitos deles falharam. Na verdade, esses planos preveem mudanças bruscas e importantes que tendem a empurrar a empresa privatizada na armadilha de aceleração (acceleration trap). Um tipo de 'burnout organizacional' (organizational burnout) onde a exaustão e a resignação da força de trabalho afetam drasticamente o desempenho da empresa. A tese, portanto, focalizou em estudar a ligação entre um processo de privatização e o risco de cair na armadilha de aceleração. Uma investigação preliminar sobre a literatura das mudanças empresariais permitiu a concepção de um quadro preliminar teórico que sugere a existência de dois moderadores (moderators) deste relacionamento entre um processo de privatização e a armadilha de aceleração: um 'choque cultural' (cultural clash) e um 'fraco clima de liderança transformacional' (weak transformational leadership). Em seguida, um estudo de caso - baseado numa empresa de telecomunicações europeia e conduzido através de uma abordagem metodológico não puramente indutivo (non-purely inductive approach) - confirma, mas também aprofunda a compreensão da ação desses dois moderadores. A respeito do moderador 'choque cultural' (cultural clash moderator), a análise de dados do estudo de caso da empresa de telecomunicações europeia mostra a importância exercitado tanto por um 'choque de identidade corporativa' (corporate identity conflict) como por um 'conflito de identidade gerencial' (management identity conflict). Quanto ao moderador 'fraco liderança transformacional', a análise dos dados destaca o papel da 'falta de confiança na nova gerência' (lack of trust in the new management), mas também de 'sentido do trabalho' (lack of job sense), principalmente através da perda de 'orgulho no trabalho' (loss of proudness). Finalmente, a análise dos dados salienta que a 'não aceitação do novo sistema de incentivos' (non-acceptance of the new incentive system) afeta significativamente a relação entre a privatização e a armadilha de aceleração, contribuindo tanto para um 'choque cultural' como para um 'fraco clima de liderança transformacional'. / The privatization of a company is a disruptive shift that generally coincides with the end of a monopoly position and the subsequent entry into the competitive game. The challenges that it raises are so arduous that they tend to lead the leadership to execute massive corporate changes. Yet, the literature shows that many of them fail. In fact, those plans envisage abrupt and severe changes that tend to push the privatized company into the acceleration trap: a type of organizational burnout where the exhaustion and the resignation of the workforce affect dramatically the performance of the company. The thesis has therefore focused on studying the link between a privatization process and the risk of falling into the acceleration trap. An initial investigation into the corporate change literature has permitted to design a preliminary theoretical framework, which has suggested the existence of two moderators of the relationship between privatization and acceleration trap: a cultural clash and a weak transformational leadership climate. Then, a single case study - based on a European telecommunication company and driven through a non-purely inductive approach – has confirmed but also deepened the understanding of the action of those two moderators. Regarding the cultural clash moderator, the data analysis of the company’s case study shows the importance played by not only a corporate identity conflict but also by a management identity clash. With regard to the weak transformational leadership climate moderator, the data analysis highlights the role of lack of trust in the new management but also of job sense, particularly through a loss of proudness. Finally, it also derives from the data analysis that the non-acceptance of the new incentive system also significantly affects the relationship between privatization and acceleration trap by contributing to both a cultural clash and a weak transformational leadership climate.

El modelo transformacional de la gramática generativa en la práctica de la subtitulación : Aplicación destinada a transmitir la significación y superar las limitaciones espacio-temporales / The Transformational Model of the Generative Grammar applied to Subtitling

Ibero, Carlos January 2014 (has links)
Subtitling is a discipline within the Audiovisual Translation (AVT) field that requires some special techniques and strategies to channel the information from a multichannel and polisemiotic document into a written text within the screen. It’s a constrained translation that demands an additional effort to convey the content and the form of the source text into the target one. The aim of this paper is to analyse whether the model of the kernel sentences and clausal ranks of the generative-transformational grammar would work as a more systematic method to extract the essential information of the audiovisual text and organize it in more concise and reduced units of text, i. e., the subtitles. We will also analyse whether this linguistic approach will be enough to meet our objective or if, on the other hand, other extralinguistic aspects intervene. The texts we will be using for our study are Roy Andersson’s commentary on three deleted scenes of his film “Songs from the second floor” and the documentary Den lilla människans storhet, a behind-the-scenes or making-of on the same feature.
