Coloured Logic Petri Nets and analysis of their reachable trees

Logic Petri nets (LPNs) can describe and analyse the batch processing function and passing value indeterminacy in cooperative systems, and alleviate the state space explosion problem. However, the indeterminate data of logical output transitions cannot be described explicitly in LPNs. Therefore, Coloured Logic Petri nets (CLPNs) are defined in this paper. It can determine the indeterminate data of logic output transitions in LPNs, i.e., the indeterminate data can be represented definitely in CLPNs. A vector matching method is proposed to judge the enabling transitions and analyse CLPNs. From the marking equation and the proposed reachable tree generation algorithm of CLPNs, a reachable tree can be built, and reachable markings are calculated. The advantage of CLPNs can be shown based on the number of leaf nodes of the reachability tree, and CLPNs can solve the indeterminate data of logical output transitions. Finally, an example shows that CLPNs can further reduce the dimensionality of reachable markings.     

New public management and organisational commitment in the public sector: testing a mediation model

This paper focuses on the attitudes of learning professionals towards New Public Management (NPM). In a survey of the UK further education sector (n = 433), NPM beliefs were found to be positively associated with both affective and normative organisational commitment. However, as expected, NPM beliefs were not found to be related to continuance organisational commitment. The results also show that although perceived organisational support mediates the relationship between NPM beliefs and affective organisational comment, it is only a partial mediator of the relationship between NPM beliefs and normative organisational commitment. The theoretical and practical implications of these findings, and potential directions for future research, are discussed.     

Supervisor and coworker support: a source congruence approach to buffering role conflict and physical stressors

The buffering effects of supervisor support on the stressor–strain relationship have proven elusive in prior research (Beehr, Farmer, Glazer, Gudanowski and Nair (2003), ‘The Enigma of Social Support and Occupational Stress: Source Congruence and Gender Role Effects,’ Journal of Occupational and Health Psychology, 8, 220–231). We built on emerging work on source congruence and conservation of resource theory to test a series of hypotheses intended to clarify these mixed findings. Using a sample of 768 employees from 45 organizations in North America, results from moderated regression analyses, showed that the effects of supervisor support on the stressor–strain relationship depended on source congruence. In accordance with our predictions, although we found buffering effects for the physical stressors–strain relationship, we found a reverse buffering effect for the role conflict–strain relationship. These differential buffering effects did not emerge when considering coworker support. We discuss the implications of our results for shedding light on the mixed evidence regarding buffering work stressors reported in prior research.     

Perceived organizational support and expatriate performance: understanding a mediated model

What are the mechanisms by which multinational corporations (MNCs) can facilitate the effective performance of their expatriate staff in foreign countries? There is a substantial literature on expatriation, yet few studies have addressed how perceived organizational support (POS) may impact upon expatriates' work adjustment and affective commitment, and then on their job performance. We use data on 118 expatriates working at the German subsidiaries of Japanese MNCs, and demonstrate that career POS has a direct positive influence on work adjustment and affective commitment. Our results indicate that work adjustment fully mediated the relationship between career POS and task performance. We further discovered that both work adjustment and affective commitment play a pivotal role in mediating the impact of career POS on contextual performance. We discuss the practical implications of these findings and provide suggestions for future research.     

A multiple group analysis of the training transfer model: exploring the differences between high and low performers in a Korean insurance company

This study suggests an integrative transfer of training model and examines the influence of pre-training performance on the relationship between work environment variables and transfer-related variables. Structural equation modeling was conducted with data collected from 365 Korean employees of a large general insurance firm. They were all participants in a leadership development program. The results of multi-group analyses revealed that the influence of work environment variables on transfer-related variables was moderated by employees' pre-training performance. The findings of the study imply that a more elaborate training transfer model that considers performance not just as an outcome variable, but also as an antecedent variable is required. Also, it is proposed that different strategies should be applied to promote transfer of training based on the employee's level of pre-training performance.
