The study methods were adopted literature review and questionnaire. In questionnaire aspect, the subjects included 502 elementary school teachers in Taipei City and Taipei County. The collected data were analyzed through the methods of descriptive statistic, t-test, one-way ANOVA, Pearson’s product-moment correlation, and multiple stepwise regression analysis. It is hoping that through this design to collect and understand the relationship between school learning culture and teacher professional commitment as well as real life phenomenon of the researched subject. Conclusions were made as followings: 1. School learning culture is above average. The best dimension is the structure and system of promoting teacher learning. 2. Teacher professional commitment is above average. The best dimension is the professional moral. 3. Teachers among diverse background variables take a different view on school learning culture, except the highest academic background and school location. 4. Teachers among diverse background variables take a different view on teacher professional commitment, except the sex, school location and school history. 5. Teachers who get higher scores on school learning culture would get higher scores on teacher professional commitment, too. 6. There is positive correlation existed between the learning culture and teacher professional commitment. 7. Among all dimensions of school learning culture, the highest prediction to total teacher professional commitment is the structure and system of promoting teacher learning. In the last part, the researcher, based on the findings, proposes some suggestions for the education authorities, school administration, and teachers, hoping to benefit the development of school learning culture and promote school effectiveness in the future.

Magister Educationis - MEd / Student persistence is a thorn area which did not receive much publication in Namibia and South Africa. Many research focused on why students fail to persist in higher education opposed to why they succeed. This research paper mainly investigated the relationships between external communities, social and academic integration and student persistence among distance students. I used Tinto's theory of student persistence at institutions of higher learning as my theoretical approach. The study employed a qualitative approach with a phenomenological design. I collected data by interviewing senior distance students at a certain public university in Southern Africa. The findings of this research revealed that the majority of students are self-driven which gave an impression that self -motivation and intentions of participants contribute significantly to student persistence. Indications are that informal peer group support contributes considerably to student persistence. The overall outcomes suggest that support from family members and employers positively influence students' academic progress and success. This study generally suggests that there is a positive relationship between external communities and student persistence opposed to what many scholars suggested.

Recent studies indicate that employees distinguish between commitments to interpersonal foci within the organization, such as supervisors and coworkers. Often, these commitments account for variance in outcomes incremental to organizational commitment (e.g., Becker, 1992). Unfortunately, research has tended to focus on affective forms of commitment to foci, while ignoring normative and continuance commitment. To address this gap, the current study proposed and tested models of commitment to foci which incorporate normative and continuance commitment in addition to affective commitment. Results showed some parallels with findings concerning organizational commitment. Much like organizational commitment, support from a focus relates to affective commitment to that focus, while expectations from a focus predict normative commitment to the focus. Additionally, both affective and normative commitment to supervisors and coworkers predicted favorable outcomes, but continuance commitment did not. In line with researchers recommendations (e.g., Johnson, Groff & Taing, in press), interactions among different bases and foci of commitment were also examined. Exploratory analyses suggested a three-way interaction between affective organizational, supervisor, and coworker commitment for predicting in-role performance.

Desde o surgimento do sistema Last Planner de controle da produção (LPS), no início dos anos 90, vários estudos apontaram a necessidade de compreender a teoria fundamental na qual o sistema é baseado. A Perspectiva da Linguagem‐Ação (LAP) é sugerida na literatura como adequada para compreender o gerenciamento dos compromissos no LPS. Entretanto, os estudos que comparam estas abordagens discutem a relação em um âmbito teórico. Neste sentido, há uma falta de estudos empíricos que tenham investigado as vantagens de compreender um sistema de planejamento segundo a LAP. O objetivo deste trabalho é analisar os benefícios e limitações da utilização da Perspectiva da Linguagem‐ Ação para avaliar sistemas de planejamento e controle da produção, com ênfase nos níveis de médio e curto prazo. Foram realizados dois estudos de caso em empresas diferentes, ambas com um bom nível de maturidade na utilização do LPS, mas que apresentavam diferenças substanciais na forma de realizar o planejamento e controle da produção. Durante a condução dos estudos foram utilizadas entrevistas semiestruturadas com engenheiros, auxiliares e encarregados; observação direta ao canteiro de obras; análise de documentos; e participação nas reuniões de planejamento de médio e curto prazo como fontes de evidência. Em cada um dos casos foi realizado um mapeamento das redes de compromissos relativas ao planejamento, bem como uma análise aprofundada sobre como são realizadas as reuniões, como os compromissos são gerenciados e quem efetivamente participa da tomada de decisão. Em ambos os estudos foi possível rastrear como os compromissos são iniciados. Este rastreamento levou a uma análise sobre a integridade dos ciclos nas redes de compromissos, e as consequências dessas falhas para o sistema de planejamento. Finalizadas as análises individuais foi feita uma análise cruzada dos casos estudados, em que foi possível perceber as diferenças das abordagens de cada empresa na condução do planejamento. As análises dos casos indicaram que existem alguns problemas presentes no sistema de planejamento que são melhor compreendidos através da análise das redes de compromissos. Além disso, as análises das reuniões apontaram algumas limitações no método proposto na literatura para avaliar as discussões entre duas pessoas que levam a execução de uma ação. Desta forma, este estudo elaborou um método que tornou possível analisar os acordos estabelecidos nas reuniões de planejamento, de maneira a contornar as limitações encontradas. / Since the Last Planner™ System (LPS) was devised in the early Nineties, several studies have pointed out the need to understand the underlying theory in which it is based on. The Language‐Action Perspective (LAP) has been suggested as a suitable approach to understand the management of commitments in the LPS. However, there is a lack of empirical studies that have investigated the utility of LAP as a theoretical approach for explaining the LPS. This study aims to investigate the benefits and the limitations of the Language‐Action Perspective for evaluating the effectiveness of planning and control systems, emphasizing medium and short term planning. Two case studies were carried out in different construction companies, both of them highly experienced on the use of LPS. Interviews with the people involved in planning meetings, direct observation of the construction sites, participation in planning meetings, and documents analysis were the main sources of evidence. In each company, the production planning and control system of one project was assessed, based on the mapping of the network of commitments regarding the medium and short term planning levels. Besides, an in‐depth analysis of planning meetings was made, describing how they were carried out, who effectively participated in decision‐making, and how the commitments were managed. In both studies, it was possible to track how the commitments were initiated, and in some cases to analyse the integrity of the workflow loops in the network of commitments, and the consequences of the failures for the planning and control system. A cross‐case analysis was carried out, in order to compare the managerial approaches of the two companies. The results pointed out some problems in the planning and control processes that can be better understood through the mapping of the network of commitments. Moreover, the study indicated some limitations of the method proposed in the literature for analysing people’s speech. For that reason, this study devised a method to perform a detailed analysis of planning meetings, in order to overcome those limitations.

Les objectifs des entreprises n’ont pas cessé d’évoluer. Traditionnellement, la maximisation du profit a été considérée comme l’objectif ultime de l’activité de toute entreprise. Aujourd’hui, les managers déclinent plusieurs autres objectifs comme le profit à long terme plutôt qu'à court terme, l’image de marque, ou encore le respect de l’environnement (Boiral, 2006). Ainsi, pour identifier les motivations d’engagement des entreprises dans la responsabilité sociale (RSE) nous avons mobilisé, l’ensemble de la revue de littérature sur le sujet, en se basant sur le cadre d’analyse multi-niveaux identifié par Wood (1991). Cette étude nous a permis de mettre en place un modèle de recherche sur trois niveaux qui explique les motivations d’engagement des entreprises dans la RSE. Ce modèle de recherche a été testé sur 94 entreprises qui œuvrent dans le secteur industriel Algérien. Les résultats ont confirmé en partie nos hypothèses. Par conséquent, l’engagement volontaire des entreprises dans la RSE s’explique par : les valeurs idéalistes du chef d’entreprise, la réduction des coûts de production, l’anticipation sur la législation, l’avantage concurrentiel, la subvention de l’état et à la taille de l’entreprise. / The objectives of the compagnies have not stopped evolving. Traditionally profit maximization was considered as the ultimate goal of any business activity. Today, managers declined several alternative objectives such as long term profit rather than short one, brand, or respect for the environment, Boiral (2006). Thus, to identify the corporate commitments motivations into the social responsibility (CSR), we investigated all literature on the subject, based on the analysis of multi- level framework identified by Wood (1991). This study has allowed us to establish a research model on three levels, which explains the motivations of corporate commitments to CSR. This research model has been tested on 94 companies operating in the Algerian industrial sector. The results partly confirmed our hypotheses. Therefore, the compagnies voluntary commitment in CSR is explained by the idealistic values of the entrepreneur, the reduction of production costs, the anticipation of the legislation, competitive advantage, the state subsidy and the company size.
