ABSTRACT Nonlinear and dynamic approaches are two main principles of complex systems. The work and organizational psychology field has recently applied these concepts to understand human behaviour at work. In this introductory paper, we describe how human behaviour at work can be understood from a nonlinear and dynamic perspective, developing and applying the advantages of this approach to continue moving beyond the frontiers of our knowledge. We focus on the theoretical, methodological, and epistemological implications of the nonlinear dynamic approach in the field. Then, we present the five papers included in this special issue. These papers have applied nonlinear and dynamic concepts to understand a wide range of phenomena: subordinates-supervisors relationships, team behaviour, deviant workplace behaviour, transformational leadership, and training transfer. Overall, these papers demonstrate the utility of nonlinear dynamics in our field and how we can create more time-sensitive and complex knowledge by paying special attention to when and how phenomena happen and how such phenomena interrelate over time. 相似文献

ABSTRACTThe nature of work and the contexts in which firms operate have changed significantly in the many decades since the study of psychological contracts (PCs) at work began in earnest. These changes have altered the contours of the traditional employer-employee relationship and are key motivators of this Special Issue. We seek to chart new directions for PC research over the next decade by widening the theoretical and methodological lenses used to explore PC processes. In the introductory editorial we briefly outline the PC construct, overview the collected papers, and discuss the next exciting wave of PC research (exploring PC dynamics, PC counterparties, and the PC context) inspired by this collection. 相似文献

A review of the organisational psychology literature suggests that researchers have examined at least four job attitude constructs: job satisfaction, work/task satisfaction, job involvement, and organisational commitment. Less, however, is known about why the four different job attitudes vary in magnitude as predictors of vital organisational outcomes. In this systematic review, I propose that positive affect is central in explaining the differential effects of these job attitudes on organisational outcomes. The review then explicates patterns of results underlying prior studies on these job attitudes and presents an overarching proposition: Accurate conceptualisation and measurement of the affective component underlying each job attitude will help illustrate how, and to what extent, each job attitude leads to desirable organisational outcomes. Finally, four key suggestions for further job attitudes research are presented: (a) enhancing conceptualisation and measurement of positive affect in job attitudes, (b) developing an overarching theory of positive affect, (c) focusing on discrete positive emotions, and (d) looking beyond existing current job attitude constructs. This work complements the current affective epoch of job attitudes research, uncovering the trail of positive affect as it has informed the job attitudes literature historically and suggesting its theoretical and practical developments for the future. 相似文献

Train and heavy vehicle drivers can experience a traumatic event caused by people attempting suicide by crashing into their vehicles or jumping in front of them. While there are a number of studies on train drivers showing the negative consequences these events can have on their well-being, there are no studies on heavy vehicle drivers involved in these types of crashes. In the current study, we surveyed Finnish heavy vehicle drivers (N = 15) involved in a suicide crash in the year 2017 regarding their experiences and coping approximately one month (T1) and one year (T2) after the crash. Ten of these drivers reported one or various combinations of measurable consequences such as minor physical injuries, shorter or longer sickness absences, significant posttraumatic stress symptoms (measured using the Impact of Events Scale-Revised) and requiring psychological help. Posttraumatic stress symptoms decreased over time; however, three out of the four drivers who had a high IES-R score at T1 were still around the IES-R cut-off score at T2. This research raises questions whether and what kind of support heavy vehicle drivers who have been involved in a suicide crash should be given. 相似文献

Empathy is a complex socio-emotional behavior that results from the interaction between affective and cognitive mechanisms. Equipping embodied conversational agents (ECAs) with empathic capacity can benefit from the integration and evaluation of these low and high level capabilities in a hierarchical manner. Following the theoretical background on empathic behavior in humans, this paper presents a framework to equip ECAs with real time multi-modal empathic interaction capabilities. We present the implementation of this framework, which includes basic dialogue capabilities as well as three levels of empathic behavior in a conversational scenario. Our approach is an inclusive stand on modeling levels of empathy and provides a baseline behavior for empathic interaction. 相似文献

Professional career paths are nowadays marked by multiple transitions. Job loss is one of the most frequent causes of professional transitions. Given this emphasis, recent studies questioned a possible evolution of the “work” norm, the emergence of an “unemployment norm” and its effects on job seekers. This paper proposes to contribute to the discussion on the current evolution of the relation to work and unemployment. At first, the results of a study with 500 unemployed people, who completed a questionnaire on work centrality and on the perception of work, will be presented. Then, a discourse analysis on the meaning and meaningfulness of work of 15 working people will be discussed. The results show the central function of work and the relative normalization of unemployment. 相似文献

In this paper, a novel cognitive architecture for action recognition is developed by applying layers of growing grid neural networks. Using these layers makes the system capable of automatically arranging its representational structure. In addition to the expansion of the neural map during the growth phase, the system is provided with a prior knowledge of the input space, which increases the processing speed of the learning phase. Apart from two layers of growing grid networks the architecture is composed of a preprocessing layer, an ordered vector representation layer and a one-layer supervised neural network. These layers are designed to solve the action recognition problem. The first-layer growing grid receives the input data of human actions and the neural map generates an action pattern vector representing each action sequence by connecting the elicited activation of the trained map. The pattern vectors are then sent to the ordered vector representation layer to build the time-invariant input vectors of key activations for the second-layer growing grid. The second-layer growing grid categorizes the input vectors to the corresponding action clusters/sub-clusters and finally the one-layer supervised neural network labels the shaped clusters with action labels. Three experiments using different datasets of actions show that the system is capable of learning to categorize the actions quickly and efficiently. The performance of the growing grid architecture is compared with the results from a system based on Self-Organizing Maps, showing that the growing grid architecture performs significantly superior on the action recognition tasks. 相似文献

ObjectivesThere is a need to develop more effective physical activity (PA) promotion programs for college women. Theory and evidence suggest that perceptions of the social environment play a role in college women’s PA, though little is known about how these perceptions are associated with PA at the day level. The goal of this study was to examine relations between changes in college women’s daily social perceptions and objectively assessed PA over seven days.DesignDaily diary method.MethodCollege women (n = 80, MAge = 20, MBMI = 23.1 kg/m2) wore Fitbit wristbands and completed daily self-reports of (1) the quantity and perceived intensity of their social interactions (positive/negative), and (2) the occurrence of social comparisons (based on appearance/health/status) for seven days.ResultsMultilevel models showed daily variability in predictors and outcomes (ps < 0.0001), as well as relations between within-person changes in social perceptions and PA. Increases in negative interactions (particularly those with friends) were consistently associated with decreases in daily PA, whereas increases in positive interactions showed limited relations (srs = −0.22-0.34). Days with health comparisons were days with greater PA for women who had stronger overall interest in comparisons, but were days with less PA for women with weaker overall interest (srs = 0.22–0.33). PA did not differ between days with vs. without appearance comparisons.ConclusionsSocial perceptions show meaningful day-to-day variability and relations with college women’s daily PA, and specific associations may be useful for improving tailored interventions for college women. 相似文献
