This study aimed to examine the mediating effect of job satisfaction in the relationship between role ambiguity and organizational citizenship behavior (OCB) according to the “HEalthy and Resilient Organization” model in two local corporations.. A multilevel analysis of mediation was employed to examine the relationship between these variables, controlling for the effect of employee division. The sample consisted of a total of 340 employees. The results indicate that job satisfaction exhibits a total mediation in the relationship between role ambiguity and OCB of public employees. These results indicate the importance of employees’ well-being to decrease negative effects of role ambiguity in publicemployees’ performance. / El objetivo del estudio era examinar el efecto mediador de la satisfacción laboral en la relación entre la ambigüedad de rol y la conducta de ciudadanía organizacional (CCO) en dos corporaciones locales basándonos en el modelo “HEalthy & Resilient Organization” (HERO; Salanova, Llorens, Cifre & Martínez, 2012). Se propuso un modelo de mediación multinivel entre estas variables, controlando el efecto de la pertenencia de los empleados a sus unidades. 340 empleados públicos participaron en la muestra. Los resultados confirman un efecto mediador total de la satisfacción laboral entre la ambigüedad de rol y la CCO. Este resultado tiene importantes implicaciones en el bienestar de los empleados, al reducir los efectos negativos de la ambigüedad de rol en el desempeño de los empleados públicos. / O objetivo do estudo foi examinar o efeito mediador da satisfação no trabalho na relação entre a ambiguidade do papel é o comportamento de cidadania organizacional (CCO) em duas empresas públicas locais, a proposta do estudo esteve baseada no modelo Healthy & Resilient Organization (HERO; Salanova, Llorens, Cifre & Martínez, 2012).

Notre travail doctoral vise à étudier l'impact du contexte social de l'organisation à un premier niveau, sur les perceptions des employés des ruptures du CP et à un second niveau, sur la performance au travail. Nous soutenons que la perception des employés de la rupture du CP est fortement subjective, et donc, qu'elle dépend majoritairement des repères sociaux que l'employé capte en observant la façon dont l'organisation traite les autres employés. S'appuyant sur ces arguments, l'existence de relations politiques au sein de l'organisation ainsi que les processus de comparaison sociale ont été plaidés comme facteurs contextuels sociaux influençant la perception des employés de la rupture du CP et leurs comportements subséquents de performance au travail. L'enquête a été réalisée sur un échantillon non aléatoire de 322 dyades subordonné-superviseur. Le test des hypothèses a démontré que le contexte social négatif est positivement associé à la rupture du CP au niveau transactionnel et au niveau relationnel. Les ruptures des CP transactionnel et relationnel ont des effets significatifs et négatifs sur les comportements volontaires et obligatoires des employés. L'effet est d'ailleurs légèrement plus fort pour les comportements volontaires que pour les comportements obligatoires. L'importance perçue des promesses non tenues a des effets modérateurs significatifs sur la relation entre la rupture des CP transactionnel et relationnel et sur les comportements volontaires des salariés. En revanche, cette importance n'a pas d'effet modérateur significatif sur la relation entre la rupture du CP et les comportements obligatoires des salariés. / The current study is aimed at investigating the impact of organizational social context on employees' perceptions of PCB and subsequent performance behaviors. We argued that employee's perception of PCB is highly subjective in nature, thus, heavily depends on social cues the employee picks up from the organization's treatment to other coworkers. Based on these arguments, organizational politics and social comparison processes (positive and negative comparisons) were argued as social contextual factors that influence employee's perception of PCB and subsequent performance behaviors. A non-random purposive sample of 322 subordinate-supervisor matching dyads, with 60% response rate, collected from various public & private organizations of Pakistan. The SR model results demonstrated that the negative social contextual factors (organizational politics & negative comparison) had significant positive associations with both transactional and relational PCB. However, the positive social contextual factor (positive comparison) had non-significant effects on both transactional and relational PCB. Both transactional and relational PCB had significant negative effects on employees' extra-role (OCB-I) and in-role behaviors, and the effect size was, slightly, greater for extra-role than in-role behaviors. Perceived importance of broken promises showed significant moderating effects only for the relationship between PCB (transactional & relational) and employees' extra-role behaviors (OCB-I) but not between PCB and in-role behaviors.

本研究主要目在於針對教師組織公民行為構念的界定作進一步的釐清並結合社會交換理論、人格理論、工作內在動機、印象管理動機、以及組織文化等觀點，提出以校長與教師交換關係、教師自我監控與工作投入為個人層次預測變項，個人/集體主義為團體層次預測變項之教師組織公民行為前置因素之跨層次模式，再透過階層線性模式方法分析以探討這些前置變項對教師組織公民行為之影響以及他們之間的關係。研究採用調查研究法，以台北市37所公立國民中學教師為對象，發出925 份問卷，最後回收736份有效問卷，有效問卷回收率則為79.57％。本研究主要研究發現為: (一)教師組織公民行為應視為一個聚合模式多層面構念；(二)教師工作投入為相對最重要教師組織公民行為前置因素；(三)人格特質對教師組織公民行為的影響主要是間接透過工作投入的中介效果；(四)不同類型組織公民行為的前置因素以及效果互有差異。 / The main purpose of current study was to revisit the construct validity issues of organisational citizenship behavior and to investigate the dynamics of teachers’ organizational citizenship behavior antecedents. Based on theories of social exchange, personality, job intrinsic motivation, impression management and organizational culture, a multi-level model of teahers’ organizational citizenship behavior antecedents was proposed where leader-member exchange, self-monitering and job involvement serve as individual level antecedents, individualistic/collectivism as school level antecedent and teachers’ organizational behavior as outcome variable at individual level. Valid data was collected from 34 public junior higher schools and 736 teachers in Taipei city. The main findings can be summarised as follows: (1) teacher organizational citizenship behavior should be treated as a aggregated model multidimensional construct; (2) Relatively teachers’ job involvement is the strongest antecedent for three dimensions of OCB; (3) the effect of teachers’ conscientiousness on OCB is mediated by teachers’ job involvement; (4) the antecedents included in current study have varied significant or insignificant effects on three dimensions of teachers’ OCB.

企業社會責任(corporate social responsibility，簡稱CSR)的概念與實務發展在近年來已成為一門企業永續經營的顯學。本研究認為，有別於一般組織外部利害關係人的觀點，身為內部觀察者的員工身分具有特殊性，不僅較外部利害關係人更接近公司核心，亦有機會參與公司的企業社會責任政策制定與活動。因此，本研究旨在建構一研究模型，以員工觀點了解企業社會責任認知及企業志工參與對組織公民行為之影響過程與結果，包含探究員工對企業社會責任認知與企業志工參與程度是否與組織認同有正向影響？員工企業社會責任認知與組織認同是否為知覺外部聲望所中介？當員工組織認同提高時，是否增進其工作滿足、組織承諾、顧客導向？ 　　本研究以Kim et al.(2010)所提出的企業社會責任影響員工企業認同模型概念為基礎，並拓展員工可能展現的反應及工作態度構念，以便利抽樣法回收有效紙本問卷201份、有效網路問卷115份，共計獲得316份樣本。經由驗證性因素分析與結構方程模式(Structural Equation Modeling, SEM)分析後得出研究結論如下： 1.知覺外部聲望確實為企業社會責任認知程度與組織認同之中介變數，員工的企業社會責任認知程度對知覺外部聲望有正向的影響，而更進一步影響組織認同。 2.企業志工參與和組織認同具有正向關係，佐證當企業的社會責任相關活動能滿足員工的心理需求時，員工將會傾向認同該企業。 3.組織認同與顧客導向、工作滿足及組織承諾皆存有正向的影響關係。 4.顧客導向、工作滿足和組織承諾皆與組織公民行為有正向的影響關係，其中顧客導向和組織承諾的影響力皆大於工作滿足。 / The increasing development of corporate social responsibility has become a prevalent concern for business sustainability practices. In comparison to the viewpoint of outside stakeholders, employees play unique roles for their company for two reasons: (1) employees are closer to corporate core business (2) employees participate more easily in CSR activities and policy formulation. Therefore, this study aims to establish a model to understand how employees’ perceived CSR and participation in employee volunteer program (EVP) relate to their organizational citizenship behavior. This study also investigates whether perceived CSR and EVP participation has positive effects on organizational identification; whether perceived external prestige mediates the relationship between perceived CSR and organizational identification; and whether organizational identification acts as the antecedent of job satisfaction, organizational commitment and customer orientation. The model concept is based on the model of CSR and employee-company identification established by Kim et al. (2010), and modified by adding some employees’ attitude constructs. The survey, conducted by convenience sampling, consists of a total of 316 participants whose companies have EVP. Utilizing confirmatory factor analysis (CFA) and structural equation modeling (SEM), the results are as follows: 1.Perceived external prestige is a partial mediator between perceived CSR and organizational identification. Meanwhile, perceived CSR positively affects perceived external prestige, and perceived external prestige has positive relationship with organizational identification. 2.The relationship between EVP participation and organizational identification is positive, which means employees tend to identify with their company when they are mentally satisfied by CSR activities. 3.Organizational identification positively affects variables, such as customer orientation, organizational commitment and job satisfaction. 4.The attitude factors that positively affect employees’ organizational citizenship behavior include customer orientation, organizational commitment and job satisfaction. Further, the impact of customer orientation and organizational commitment are greater than job satisfaction.

Observa-se que, apesar do uso extensivo de práticas de GP, falhas em relação ao atendimento do cronograma e orçamento são amplamente relatadas. Portanto, este trabalho tem como objetivo principal analisar a influência das práticas de gestão de projetos e do objetivo de desempenho no Comportamento de Cidadania Organizacional (OCB) da equipe de projetos. As dimensões que compuseram o OCB foram: Ajuda, Iniciativa e Compliance. Para testar a relação entre os fatores de práticas de GP (incipientes ou avançados) e objetivo de desempenho (normal ou desafiador) no comportamento da equipe foi utilizada a metodologia do experimento baseado em cenários (SBRP experiment). A amostra contou com 216 alunos de graduação e pós-graduação em administração. O estudo mostrou que a utilização de práticas em gestão de projetos não influenciou o Comportamento de Cidadania Organizacional da equipe de projetos. Entretanto, o objetivo de desempenho nas dimensões de tempo e custos influenciou o Comportamento Cidadão da equipe de projetos. Além desses resultados, a pesquisa mostrou que características pessoais, como experiência em liderar projetos, influenciou a propensão em aumento do comportamento cidadão mediante uma remuneração adicional. Como contribuição adicional este estudo mostra que existem diferenças de resultados nos diferentes grupos de respondentes (alunos de graduação e pós-graduação em administração), conforme encontrado em outros estudos. A utilização do experimento também foi um diferencial metodológico, em virtude de sua ainda baixa utilização em gestão de operações. Finalmente, este estudo também identificou as principais práticas utilizadas na gestão de projetos. / Practices in project management (PM), although widely disseminated, utilized and researched, do not guaranteee the project performance (success) in their deliveries on time and costs as planned. It is observed that, despite the extensive use of PM practices, failures to meet the schedule and budget are widely reported. Thus, this thesis aims to analyze the influence of PM practices and performance targets on the project team's Organizational Citizenship Behavior (OCB). The dimensions that composed OCB were: Help, Initiative and Compliance. To test the relationship between the factors of PM practices (incipient or advanced) and performance targets (ordinary or challenging) in team behavior, the scenario-based role-playing experiment (SBRP experiment) was used, as research methodology. The sample consisted of 216 undergraduate and post graduate students in business administration. The research showed that the use of practices in project management did not influence the project team’s Organizational Citizenship Behavior (OCB). However, performance targets in time and costs influenced the project team’s OCB. In addition to these results, the research showed that personal characteristics, such as experience as project manager, influenced the propensity for increasing OCB based on additional payment. As an additional contribution this study shows that there are differences in the results for different groups of respondents (undergraduate and post graduate students in business administration), as found in other studies. The use of the SBRP experiment was also a methodological advantage, seeing that is has not been widely used in operations management. Finally, this study also identified key practices in project management.

Se por um lado, a sua importância e inferência na performance dentro do contexto empresarial têm sido crescente, caracterizando a necessidade de um entendimento cada vez maior por parte das empresas, por outro, o investimento das corporações de grande porte, caminham cada vez mais em direção dos países com crescimento exponencial sustentado, como são o BRIC, o que cna uma necessidade fomentada de pesquisa nesta área de pesquisa para estas regiões. Este estudo pretendeu investigar, avaliar e mapear a influência do capital e do CCO na satisfação de vida e desempenho no trabalho do funcionário de nível superior, no contexto empresarial brasileiro e português, com o objetivo de identificar quais as diferenças existentes nestes duas realidade, devido ao investimento crescente do segundo para com o primeiro. Genericamente, encontramos clara influência das dimensões do CCO tanto para o desempenho no trabalho como para a satisfação de vida do trabalhador, assim como presença também marcada das duas dimensões do capital Social. Mais especificamente, foi entendido pelo nosso estudo que a realidade empresarial brasileira necessita que as empresas criem mecanismos que fomentem os laços entre colegas, a conscienciosidade, altruísmo e virtude cívica dos seus funcionários, pois assim aumentará o desempenho. Já para o contexto português, apenas a conscienciosidade e a virtude apresentaram significativa relação. Desta forma, conclui-se que para o investimento das empresas português no Brasil, estas precisam ter atenção à dimensão estrutural - relação com colegas - promovendo-a e à necessidade patente que os brasileiros têm de ajudar os seus colegas - comportamento altruísta - para aumentar o desempenho no trabalho. No que se refere a satisfação de vida, que se mostrou estreitamente relacionada com o desempenho, o brasileiro apenas precisa notar confiança nos colegas, senti-se altruísta e consciencioso, ao passo que o português necessita criar fortes laços com os colegas, mas não fomentar o comportamento altruístico. Desta forma as empresas investidoras apenas precisam ter atenção mais uma vez a necessidade de prestar ajuda especifica que o brasileiro sente, promovendo workshops com os próprios funcionários, por forma a estes passarem o seu conhecimento, monitorias, estágios, entre outros. Estes resultados demonstraram que cada continente, país (possuidor ou não da mesma língua) e/ou cultura comporta diferenças significativas no contexto empresarial, assim tornase difícil implementar técnicas e comportamentos internacionais e esperar que os resultados sejam exatamente iguais. Este estudo espera dar alguns instrumentos de comparação para que as empresas portuguesas entendam, a este nível, a realidade brasileira. / Since long ago, the themes of social capital and organizational citizenship behavior (OCB) have been extensively researched and studied in the V.S., though these have received little attention in terms of other international contexts. On the one hand, its importance and inference performance within the business environment have been increasing, characterizing the need for an increased understanding by firms, on the other hand, investment by large corporations, walk increasingly direction of countries with sustained exponential growth, as BRIC countries, which creates a need for research in this area encouraged the search for these regions. This study intended to investigate, assess and map the influence of capital and of the CCO in life satisfaction and job performance of top-Ievel employee in Brazilian and Portuguese business environment, in order to identify differences between those two realities, because increasing investment from the second to the first. Generally, we find clear influence ofboth dimensions ofthe CCO to perform at work and for the life satisfaction of workers, and also marked presence of the two dimensions of social capital. More specifically, it was understood by our study that the Brazilian business reality requires companies to create mechanisms that foster ties between colleagues, conscientiousness, altruism and civic virtue of its officials, as well as increase performance. As for the Portuguese context, the only virtue and conscientiousness showed a significant relationship. Thus, we conclude that for investment firms Portuguese in Brazil, they need to pay attention to the structural dimension - relationship with colleagues - promoting it and need to clear the Brazilians have to help their colleagues - altruistic behavior - to increase job performance. Regarding life satisfaction, which was closely related to performance, Brazilians need only belive in colleagues trust, I was unselfish and conscientious, whereas the Portuguese need to create strong bonds with colleagues, but not to encourage altruistic behavior. Thus investment firms only need to pay attention once again the need to assist states that the Brazilian feel, providing workshops with the employees themselves, so they pass their knowledge, tutoring, internships, among others. These results demonstrated that each continent, country (with or not possessing the same language) and / or culture involves differences in a business context, so it is difficult to implement technical and intemational behavior and expect that the results are exactly alike. This study hopes to give some means of comparison to understand that Portuguese firms at this leveI, the Brazilian reality.

Wendel (1994, p. 91) defined perceived organizational support (POS) as “organization support in terms of all things that relate to assistance and relationships amongst working peers and colleagues, which involve the feeling of need between superiors and subordinates . Rothbard (2001, p. 656) in defining job engagement (JE) listed two components which he thought were critical for its effectiveness on organizational functioning: (i) attention and (ii) absorption, with the former referring to “cognitive ability and the amount of time one spends thinking about the role”, while the latter “means being engrossed in a role and means the intensity of one’s focus on a role”. Organizational citizenship behavior (OCB) was first introduced by Organ in the 1980s and he defined the concept of organizational citizenship behavior “as discretionary behaviors by individuals (employees) that do not form part of formal requirements of a job, but are necessary and promote effective functioning of the organization (Organ, 1988)”. The objective of study was to explore the relationship between perceived organizational support and job engagement and their effect organizational citizenship behavior. Other relationships that were tested were first, the direct relationship between POS JE. Secondly, the combined effect of POS and JE on OCB. The study was conducted amongst nurses at Victoria hospital, in Alice within the Nkonkobe district municipality. The results showed a significant relationship between JE and OCB, whilst the relationship between POS and OCB was not accepted. The results for the other two hypotheses that were tested; (i) relationship between POS and JE, (ii) combined effect of POS and JE on OCB also showed that they were not accepted. The consistency scores for these variables were of international level (n=106). The Pearson correlation coefficients were used for hypothesis testing.

L’identité écologique, ou le sens que l’on donne à notre relation avec la nature ainsi qu’avec les enjeux environnementaux, constitue une facette identitaire pour laquelle l’intérêt scientifique est grandissant, considérant la situation climatique actuelle. Dans un contexte de travail, il pourrait s’agir d’un motivateur puissant non seulement pour le choix d’emploi ou d’organisation, mais également pour mener les individus à poser des actions écologiques dans leur lieu de travail. Il s’agit donc d’un levier non négligeable dans la responsabilisation environnementale des entreprises. L’étude de l’identité écologique se montre prometteuse dans la compréhension de ce qui mène les individus à poser plus d’actions environnementales dans leur vie personnelle. Toutefois, la définition du concept d’identité écologique est multiple et son application dans un contexte de travail est limitée. Par ailleurs, les instruments mesurant l’identité écologique sont à l’image des définitions existantes et sont donc limités dans leur portée, notamment en ne considérant que les aspects individuels ou sociaux de cette facette identitaire. Le premier article de la thèse a pour objectif de clarifier et unifier la définition de l’identité écologique, en répertoriant ses aspects autant individuels que sociaux et en faisant émerger ses particularités dans le contexte du travail. Grâce à l’analyse de contenu de 12 entrevues conduites auprès de travailleurs et travailleuses au Québec, huit thèmes ont été dégagés, répartis en trois grandes catégories : (1) l’identité écologique individuelle, (2) L’identité écologique sociale, ainsi que (3) la centralité et la saillance de cette facette identitaire. Les résultats indiquent que des valeurs écologiques, un paradigme écocentriste et un désir de contact et de proximité avec la nature caractérisent les attributs individuels répertoriés. Pour ce qui est de l’identité sociale, les mécanismes d’affirmation, d’identification à des groupes à vocation environnementale, ainsi que les représentations sociales de l’environnementalisme constituent les thèmes principaux inventoriés. Enfin, en comparant l’identité écologique dans la vie personnelle et au travail, il apparaît que cette facette identitaire est généralement plus saillante dans la vie personnelle, facilitant le fait de poser des actions pour l’environnement dans ce contexte. Le niveau de centralité de l’identité écologique dépendrait également de potentiels conflits avec d’autres facettes identitaires, par exemple celle associée à notre rôle au travail. Le second article possède deux objectifs : valider un questionnaire d’identité écologique et mesurer son utilité dans la prédiction des comportements de citoyenneté organisationnelle pour l’environnement (CCOE), en lien avec les pratiques managériales environnementales et le soutien du superviseur pour l’environnement. Au niveau du premier objectif, une phase de validation initiale a permis de déterminer une structure en quatre facteurs à l’instrument d’identité écologique, grâce à des analyses factorielles exploratoires (n = 513). Une seconde étude de validation a permis de confirmer cette structure par l’entremise d’une modélisation par équations structurelles exploratoires (n = 584). Pour ce qui est du deuxième objectif de cet article, un modèle de médiation en série a été proposé pour déterminer l’effet médiateur du soutien du superviseur pour l’environnement et de l’identité écologique sur la relation entre les pratiques managériales environnementales et les CCOE. Les résultats obtenus appuient ce modèle. La présente thèse contribue aux connaissances sur l’identité écologique par une conceptualisation y rassemblant ses éléments individuels et sociaux, ainsi que du travail. La création et la validation d’un instrument de mesure de l’identité écologique, ainsi que le test de son pouvoir prédictif sur les CCOE sont autant d’étapes pouvant mener à l’étude empirique du concept d’identité écologique et à la compréhension des mécanismes favorisant les CCOE. / Environmental identity, or the meaning we give to our relationship with nature and environmental issues, is a facet of identity in which scientific interest is growing, given the current climatic situation. In a work context, it could be a powerful motivator not only for choosing a job or organization, but also for leading individuals to take ecological action in the workplace. It is therefore a significant lever for corporate environmental responsibility. Studies on environmental identity are showing promise in understanding what leads individuals to undertake more environmental actions in their personal lives. However, the definition of the concept of environmental identity is multifaceted and its application in a work context is limited. Furthermore, the instruments used to measure environmental identity reflect existing definitions and are therefore limited in scope, particularly by only considering the individual or social aspects of this identity facet. The first article of the thesis aims to clarify and unify the definition of environmental identity, listing its individual and social aspects while highlighting its particularities in the context of work. Through a content analysis of 12 interviews with workers in Quebec, eight themes emerged regarding the content of environmenral identity, divided into three main categories: (1) individual environmental identity, (2) social environmental identity, and (3) the centrality and salience of this identity facet. The results indicate that environmental values, an ecocentric paradigm and a desire for contact and proximity with nature characterize the individual attributes inventoried. In terms of social identity, mechanisms of affirmation, identification with environmentally oriented groups, and social representations of environmentalism are key. Finally, when comparing environmental identity in personal life and at work, it appears that this identity facet is generally more salient in personal life, making it easier to perform environmental actions in this context. The level of centrality of environmental identity also depends on potential conflicts with other identity facets, such as that associated with our role at work. The second article addresses the other two aims of the thesis: validating an environmental identity questionnaire and measuring its usefulness in predicting organizational citizenship behaviors for the environment (OCBEs), in relation to environmental managerial practices and supervisor support for the environment. Regarding the first objective, two validation phases were carried out. The first determined a four-factor structure for the environmental identity instrument using exploratory factor analysis (n = 513). A second validation study confirmed this structure through exploratory structural equation modelling (n = 584). Regarding the second objective of this article, a serial mediation model was proposed to determine the mediating effect of supervisor support for the environment and environmental identity on the relationship between environmental managerial practices and OCBEs. The results obtained support this model. This thesis contributes to the body of knowledge on environmental identity by conceptualizing its individual and social elements, as well as work. The creation and validation of an instrument for measuring environmental identity, as well as the test of its predictive power on OCBEs, constitute steps that can lead to the empirical study of the concept of environmental identity and the understanding of the mechanisms promoting OCBEs.
