- Burnout and suicidal behaviours in health professionals in Portugal: The moderating effect of self-esteemPublication . Jesus, Alexandra de; Pitacho, Liliana; Moreira, AnaThe main objective of this study was to investigate the effect of burnout on suicidal behaviours and the mediating effect of self-esteem in this relationship. A total of 1172 healthcare professionals working in Portugal’s private and public sector organisations participated in this study. The results indicate a high level of burnout among these professionals and that exhaustion (β = 0.16; p < 0.001) and disengagement (β = 0.24; p < 0.001) positively and significantly affect suicidal behaviours. In turn, self-esteem has a significant and negative effect (β = −0.51; p < 0.001) on suicidal behaviours. Self-esteem moderates the relationship between disengagement and suicidal behaviours (B = −0.12; p < 0.001) and the relationship between exhaustion and suicidal behaviours (B = −0.11; p < 0.001), representing an essential variable for future lines of research, namely on the role of self-esteem in preventing burnout and suicidal behaviours in professionals from other professional areas.
- Circadian rhythms have broad implications for understanding brain and behaviorPublication . Silver, Rae; Kriegsfeld, Lance J.Circadian rhythms are generated by an endogenously organized timing system that drives daily rhythms in behavior, physiology and metabolism. In mammals, the suprachiasmatic nucleus (SCN) of the hypothalamus is the locus of a master circadian clock. The SCN is synchronized to environmental changes in the light:dark cycle by direct, monosynaptic innervation via the retino-hypothalamic tract. In turn, the SCN coordinates the rhythmic activities of innumerable subordinate clocks in virtually all bodily tissues and organs. The core molecular clockwork is composed of a transcriptional/post-translational feedback loop in which clock genes and their protein products periodically suppress their own transcription. This primary loop connects to downstream output genes by additional, interlocked transcriptional feedback loops to create tissue-specific ‘circadian transcriptomes’. Signals from peripheral tissues inform the SCN of the internal state of the organism and the brain’s master clock is modified accordingly. A consequence of this hierarchical, multilevel feedback system is that there are ubiquitous effects of circadian timing on genetic and metabolic responses throughout the body. This overview examines landmark studies in the history of the study of circadian timing system, and highlights our current understanding of the operation of circadian clocks with a focus on topics of interest to the neuroscience community.
- Competencies development: The role of organizational commitment and the perception of employabilityPublication . Moreira, Ana; Sousa, Maria José; Cesário, Francisco José SantosThe main objective of this study was to analyze the mediating effect of perceived employability (internal and external) and the organizational commitment in the relationship between the organizational practices of competencies development (OPCD) and the turnover intentions. The sample consists of 2099 participants, all of them working in organizations based in Portuguese territory. The existence of a significant and negative effect of the OPCD, of perceived internal employability and the organizational commitment in the turnover intentions, has been proven. There was also a significant and positive effect of perceived external employability on turnover intentions. Finally, the serial mediating effect of perceived employability and organizational commitment in the relationship between OPCD and turnover intentions was proven.
- Complex tasks, delegation, and flexibility: What role for engagement and shared leadership?Publication . Dionísio, António Luis; Dionísio, Andreia; Sousa, Maria José; Moreira, AnaTask complexity is one of the main factors studied by academics and is at the center of leaders’ concerns. It is related to delegation and flexibility, which are enhanced by workers’ engagement and depend on how leadership is shared. In this context, this research was carried out with the main objective of testing the serial mediating effect of engagement and shared leadership on the relationship between task complexity and flexibility and the relationship between task complexity and delegation. The sample for this study consists of 368 participants, all of whom work in organizations based in Portugal. The results indicate that task complexity is positively and significantly associated with engagement, shared leadership, flexibility, and delegation. Shared leadership has a positive and significant association with flexibility and delegation. The serial mediating effect of engagement and shared leadership on the relationship between task complexity and flexibility was confirmed. The serial mediating effect of engagement and shared leadership on the relationship between task complexity and delegation was not confirmed.
- Contrato de trabajo, compromiso y satisfacción: Moderación de la empleabilidadPublication . Cesário, Francisco José Santos; Guillén Gestoso, Carlos; Montalbán Peregrín, F. ManuelLa búsqueda de prácticas flexibles de gestión de los recursos humanos viene desempeñando un papel importante para el desarrollo estratégico de las organizaciones y en particular en contextos de profunda crisis económica y financiera como la actual en Portugal, con una situación de desempleo creciente y un clima generalizado de inseguridad laboral. Este estudio pretende examinar si la percepción de empleabilidad por parte de los trabajadores puede desempeñar un papel moderador en la relación entre formas más flexibles de contratación, como el trabajo temporal, y las actitudes laborales. Resultados sugieren que la percepción de empleabilidad puede tener un efecto moderador en la relación entre el tipo de contrato de trabajo y el compromiso afectivo y la satisfacción laboral de los trabajadores bajo contrato directo con la organización pero esta interacción no se ha encontrado para trabajadores con contrato de trabajo temporal con las Agencias de Empleo. ------ ABSTRACT ------ The search for flexible practices of human resources management comes playing an important role for the strategic organizational development and specially in contexts of deep economic and financial crisis like the present one in Portugal, with an increasing unemployment and a generalized climate of job insecurity. This study tries to examine if perception of employability by employees moderates the relationship between flexible forms of hiring, such as temporary work, and job attitudes like affective commitment and job satisfaction. Results suggest the moderating role of employability for workers under direct contract with the organization but this interaction has not been pointed for workers with an temporary work contract with Employment Agencies. ------ RESUMO ------- A busca por práticas flexíveis da gestão dos recursos humanos vem desempenhando um papel importante para o desenvolvimento estratégico das organizações e, em particular, nos contextos da profunda crise econômica e financeira como a que vive hoje Portugal, com uma situação de desemprego crescente e um clima generalizado de insegurança laboral. Este estudo pretende examinar se a percepção de empregabilidade por parte dos trabalhadores pode desempenhar um papel moderador na relação entre as formas mais flexíveis de contratação, como o trabalho temporário, e as atitudes laborais. Resultados sugerem que a percepção de empregabilidade pode ter um efeito moderador na relação entre o tipo de contrato de trabalho e o compromisso efetivo e a satisfação laboral dos trabalhadores com contrato direto com a organização, mas esta interação não foi encontrada para os trabalhadores com contrato de trabalho temporário com as Agências de Emprego.
- Developmental assets in emerging adulthood—Systematic reviewPublication . Soares, Ana Sofia; Pais-Ribeiro, José Luis; Silva, IsabelCharacterizing emerging adulthood as a period of the life course has proven to be relevant in understanding development and intervention with a focus on a positive orientation in the life course trajectory. Characterized by individualization, this period implies that people are increasingly compelled to depend on their own resources to build their life course trajectory. Identifying which resources place the person on a positive developmental trajectory becomes more relevant. Within the field of the Positive Youth Development, the Developmental Assets® model specifically focuses on which resources, that is, which personal and contextual characteristics of emerging adults can favor a positive orientation in the trajectory of the life course. The objective of this investigation is to analyze the utilization of the Developmental Assets model in the emerging adult population. In the review process, the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) protocol was applied. Research was conducted in July 2023 in electronic databases, namely: Web of Science, Scopus, Science Direct, ERIC, PsycArticles, SciELO and B-on. In this review, 13 articles published between 1999 and 2023 were included. Results indicate diversity in adopted methods, both on conceptualization of the concept and its operationalization. Results of the analysis of studies included indicate the relevance of applying the Developmental Assets model in emerging adults and the importance of its exploration in future investigations. The utilization of the model in the population of emerging adults is suggested as a strategy focusing on a positive developmental trajectory
- Dynamic spatial ability: An exploratory analysis and a confirmatory studyPublication . Oliveira, Teresa Cristina Clímaco Monteiro d'Spatial ability is included in nearly every multiple aptitude battery. However, it has been defined and evaluated in such a variety of ways that it is difficult to be precise about the meaning of the concept. A first study addresses the spatial literature, considers several measures, and empirically explores the dimensionality of the spatial domain. Nine spatial ability tests and 1 computer- administered measure were administered to a total of 104 volunteers. Results from the exploratory factor analysis identified 3 main factors: visualization, spatial relations, and dynamic spatial ability. A second study was conducted to cross-validate this factor structure. A total of 141 participants were involved in this study. Participants were recruited from professional training domains in which spatial ability has been considered important for successful performance: air traffic control, piloting, civil engineering, and architecture. Cross-validation was obtained through a confirmatory factor analysis (CFA). In general, both empirical studies confirm the existence of dynamic spatial ability as a distinct dimension within the spatial domain.
- Employees perceptions of the importance of human resources management practicesPublication . Cesário, Francisco José SantosIncreased research has been focused on establishing positive effects of HR practices on behaviors outcomes and firm performance and less attention has been taken to the perceptions of employees about the importance of the HR management practices on their professional development and career success. In particularly, we wanted to understand these perceptions under a deep economic and labor recession context, such as the one in Portugal between 2010-2014. With this assumption, our study aims to present an instrument that accurately captures employees’ perceptions of the importance of Human Resources management practices promoted by organizations. Based on literature, a written questionnaire was developed and data from 525 Portuguese workers were collected between November 2013 and January 2014. Validity of the questionnaire was analyzed and its results confirmed the existence of seven HR practices integration, training, performance management, career management, internal communication, rewards and celebration-demonstrating the questionnaire’ construct validity. Perceptions about each of the Human Resources management practices by employees were found to be positively related to global perception of HR activities, however perceptions showed a low valuation of the practices. These results encourage addressing the gap in literature with adequate measures from the point of view of employees‘ perceptions about the importance of HR activities in the Portuguese context.
- Exploring links between green HRM, greenwashing, and sustainability: The role of individual and professional TraitsPublication . Cesário, Francisco; Sabino, Ana; Palma-Moreira, Ana; Pinto-Coelho, MafaldaThis study aims to investigate the influence of Green Human Resources Management practices and greenwashing on the three pillars of sustainability—social, environmental, and economic. The moderating role of age and gender as individual characteristics and managerial position and sector as professional characteristics is also analyzed. A convenience sample of 232 respondents was used. Path analysis was employed to assess hypothesized relationships in the proposed model. Results suggest that different Green Human Resources Management practices influence social, environmental, and economic dimensions and individual and professional characteristics play a pivotal role in this relationship. Specifically, it is important to highlight the importance of green performance management and rewards and the non-significant influence of green training. Greenwashing seems to be a determinant of social and economic sustainability. The results emphasize that, for organizations to boost their employees’ perception of the three pillars of organizational sustainability, they must be aware of the specificities of their workforce and act accordingly. This work is relevant because it emphasizes the unique role of each GHRM practice as an antecedent of sustainability. It also contributes to the understanding that specific individual and professional characteristics affect the employees’ perception of sustainability.
- Guest editors' introduction: Is the HRM process important? Past, current, and future challengesPublication . Sanders, Karin; Shipton, Helen; Gomes, Jorge F. S.Ten years ago, Bowen and Ostroff (2004) criticized the one-sided focus on the content-based approach, where researchers take into account the inherent virtues (or vices) associated with the content of HR practices to explain performance. They explicitly highlight the role of the psychological processes through which employees attach meaning to HRM. In this fi rst article of the special section entitled “Is the HRM Process Important?” we present an overview of past, current, and future challenges. For past challenges, we attempt to categorize the various research streams that originated from the seminal piece. To outline current challenges, we present the results of a content analysis of the original 15 articles put forward for the special section. In addition, we provide the overview of a caucus focused on this theme that was held at the Academy of Management annual meeting in Boston in 2012. In conclusion, we discuss future challenges relating to the HRM process approach and review the contributions that have been selected—against a competitive fi eld—for this special issue. © 2014 Wiley Periodicals, Inc.
