  1. Teams as complex adaptive systems: Reviewing 17 years of research

    Ramos-Villagrasa, Pedro J.; Silva, Pedro Marques-Quinteiro Fernandes da; Navarro, José; Rico, Ramón
    At the turn of the century, Arrow, McGrath, and Berdahl portrayed teams as complex adaptive systems (CAS). And yet, despite broad agreement that this approach facilitates a better understanding of teams, it has only now been timidly incorporated into team research. To help fully incorporate the logic of teams as CAS in the science of teams, we review extant research on teams approached from a nonlinear dynamical system theory. Using a systematic review approach, we selected 92 articles published over the last 17 years to integrate what we know about teams as CAS. Our review reveals the evidence supporting teams as CAS, and the set of analytical techniques...

  2. How complexity leadership and cohesion influence team effectiveness

    Curral, Luís Alberto; Leitão, Paulo; Gomes, Catarina; Silva, Pedro Marques-Quinteiro Fernandes da; Lind, Pedro G.
    This research tested the hypothesis that enabling leadership behaviors are positively related to the objective and subjective dimensions of teamwork effectiveness. Hypotheses testing was done during a laboratory task in which 40 teams of 5 people each (N = 200) engaged in a simulation task using the pc game SimCity4. The results suggest that enabling leadership and task cohesion are not related to team performance, R2 = .08, MSE = 1.02, F(4, 35) = .79, p = .54; and that enabling leadership is positively related to team viability, mediated by task cohesion, R2 = .71, MSE = 0.31, F(4, 35) = 21.87, p < .001....

  3. Linking organizational commitment and work engagement to employee performance

    Cesário, Francisco J. Santos; Chambel, Maria José
    The need for a strong organizational commitment and a high work engagement have been frequently labelled by organization as critical success factors to achieve higher performance. But are they in fact related to employee performance? And if so, do they have the same strength and intensity as performance predictors? In this study, we used a Work Engagement Scale, commitment scale and employee performance measured through an almost real performance measure, where employees were asked to indicate the latest year’s performance appraisal rating reported by their manager. Data analysed (N = 274 workers) first confirmed the existence of a positive relation between performance and effective commitment, normative...

  4. Human resources management, citizenship behavior, and turnover intention in the portuguese public administration

    Cesário, Francisco J. Santos; Magalhães, Sara Serra De
    Framed by a social exchange perspective, this study address the issue of whether positive employees’ perceptions about human resource management practices influence positive attitudes and behaviour. We hypothesize that human resource management practices (HRMP) have a significant negative effect on intention to voluntary leave the organization and a positive effect on organizational citizenship behaviour (OCB), and that OCB could mediate the relationship between HRMP and turnover intention. A sample of 165 employees from the Portuguese public administration participated in the study. Data was analysed through descriptive statistics, confirmatory factor analysis and hypotheses were tested using single and multiple linear regressions. Results indicate that HRMP is positively associated with...

  5. Employees perceptions of the importance of human resources management practices

    Cesário, Francisco J. Santos
    Increased 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...

  6. A time to remember: The role of circadian clocks in learning and memory

    Smarr, Benjamin L.; Jennings, Kimberly J.; Driscoll, Joseph R.; Kriegsfeld, Lance J.
    The circadian system has pronounced influence on learning and memory, manifesting as marked changes in memory acquisition and recall across the day. From a mechanistic perspective, the majority of studies have investigated mammalian hippocampal-dependent learning and memory, as this system is highly tractable. The hippocampus plays a major role in learning and memory, and has the potential to integrate circadian information in many ways, including information from local, independent oscillators, and through circadian modulation of neurogenesis, synaptic remodeling, intracellular cascades, and epigenetic regulation of gene expression. These local processes are combined with input from other oscillatory systems to synergistically augment hippocampal rhythmic function. This overview presents an...

  7. Circadian rhythms have broad implications for understanding brain and behavior

    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...

  8. Guest editors' introduction: Is the HRM process important? Past, current, and future challenges

    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...
