Antecedents of leader-member exchange and explanation of its relationship with citizenship behavior

This study examined personal/interpersonal antecedents of leader-member exchange (LMX) and why and how LMX is related to the helping and voice dimensions of citizenship behavior. The results indicate that: (i) proactive personality and supervisor trust in employee were significant antecedents of LMX; (ii) the psychological empowerment dimension of autonomy partially mediated the LMX-helping relationship whereas the LMX-voice relationship was fully mediated the by autonomy and impact dimensions of psychological empowerment; and (iii) organization-based self-esteem more strongly moderated the LMX-helping relationship relative to the LMX-voice relationship.

Individual spirit at work and its relationship with employee work attitudes and organisational outcomes:An empirical examination in corporate Thailand

The purpose of this thesis is to conduct empirical research in corporate Thailand in order to (1) validate the Spirit at Work Scale (2) investigate the relationships between individual spirit at work and three employee work attitudinal variables (job satisfaction, organisational identification and psychological well-being) and three organisational outcomes (in-role performance, organisational citizenship behaviours (OCB), and turnover intentions) (3) further examine causal relations among these organisational behaviour variables with a longitudinal design (4) examine three employee work attitudes as mediator variables between individual spirit at work and three organisational outcomes and (5) explore the potential antecedents of organisational conditions that foster employee experienced individual spirit at work. The two pilot studies with 155 UK and 175, 715 Thai samples were conducted for validation testing of the main measure used in this study: Spirit at Work Scale (Kinjerski & Skrypnek, 2006a). The results of the two studies including discriminant validity analyses strongly provided supportive evidence that Spirit at Work Scale (SAWS) is a sound psychometric measure and also a distinct construct from the three work attitude constructs. The final model of SAWS contains a total of twelve items; a three factor structure (meaning in work, sense of community, and spiritual connection) in which the sub-factors loaded on higher order factors and also had very acceptable reliability. In line with these results it was decided to use the second-order of SAWS model for Thai samples in the main study and subsequent analysis. The 715 completed questionnaires were received from the first wave of data collection during July - August 2008 and the second wave was conducted again within the same organisations and 501 completed questionnaires were received during March - April 2009. Data were obtained through 49 organisations which were from three types of organisations within Thailand: public organisations, for-profit organisations, and notfor-profit organisations. Confirmatory factor analysis of all measures used in the study and hypothesised model were tested with structural equation modelling techniques. The results were greatly supportive for the direct structural model and partially supportive for the fully mediated model. Moreover, there were different findings across self report and supervisor rating on performance and OCB models. Additionally, the antecedent conditions that fostered employees experienced individual spirit at work and the implications of these findings for research and practice are discussed.

A quantitative study of the pathological changes in ten patients with multiple system atrophy (MSA)

The densities of the glial cytoplasmic inclusions (GCI), neuronal inclusions (NI), and abnormal neurons were studied in the frontal cortex, hippocampus, cerebellum, basal ganglia and areas of the pons and medulla in 10 cases of multiple system atrophy (MSA). GCI density was greater in the substantia nigra and globus pallidus compared with the frontal cortex and hippocampus. Abnormal neurons were most abundant in the frontal cortex, substantia nigra, and inferior olivary nucleus. NI and abnormal neuron densities were positively correlated in the globus pallidus but negatively correlated in the hippocampus. The NI and GCI were only positively correlated in the pons. GCI in the pons and inferior olivary nucleus, NI in the substantia nigra, and abnormal neurons in the frontal cortex varied significantly between cases. The MSA cases did not cluster according to disease subtype. The data suggest that: 1) the greatest densities of pathological changes occur in the substantia nigra and globus pallidus, 2) density of the GCI is unrelated to that of the NI, and 3) there is overlapping pathology between the various subtypes of MSA.

The DRAMA methodology for analysing strategy and its links with production system design

This paper describes a methodology: 'decision rules for analyzing manufacturing activities', which is designed to be a practical system of enquiry linking a strategic analysis to the design of production systems. The paper describes the development of the system, an industry specific design methodology, into DRAMA II which is a model that serves as an analytical tool for studying decision processes and implementation of production systems.

Full-field feed-forward equalizer with adaptive system optimization

We numerically investigate the combination of full-field detection and feed-forward equalizer (FFE) for adaptive chromatic dispersion compensation up to 2160 km in a 10 Gbit/s on-off keyed optical transmission system. The technique, with respect to earlier reports, incorporates several important implementation modules, including the algorithm for adaptive equalization of the gain imbalance between the two receiver chains, compensation of phase misalignment of the asymmetric Mach-Zehnder interferometer, and simplified implementation of field calculation. We also show that in addition to enabling fast adaptation and simplification of field calculation, full-field FFE exhibits enhanced tolerance to the sampling phase misalignment and reduced sampling rate when compared to the full-field implementation using a dispersive transmission line.

Proactive and politically skilled professionals:what is the relationship with affective occupational commitment?

The aim of this study is to extend research on employee affective commitment in three ways: (1) instead of organizational commitment the focus is on occupational commitment; (2) the role of proactive personality on affective occupational commitment is examined; and (3) occupational satisfaction is examined as a mediator and political skills as moderator in the relationship between proactive personality and affective occupational commitment. Two connected studies, one in a hospital located in the private sector and one in a university located in the public sector, are carried out in Pakistan, drawing on a total sample of over 400 employees. The results show that proactive personality is positively related to affective occupational commitment, and that occupational satisfaction partly mediates the relationship between proactive personality and affective occupational commitment. No effect is found for a moderator effect of political skills in the relationship between proactive personality and affective occupational commitment. Political skills however moderate the relationship between proactive personality and affective organizational commitment. © 2011 The Author(s).

Milyen értéket teremt a szabadidő sport és mi a kapcsolata a versenyképességgel? (What value is created by leisure sport and what is its relationship with the competitiveness?)

A sport egyre fontosabb tényezővé válik a társadalomban, és gazdasági súlya is egyre szignifikánsabban jelentkezik. A sportgazdaságtani írások nagy része azonban a hivatásos sporttal foglalkozik, a szabadidősport nem kap elég súlyt. Downward és szerzőtársai még 2009-ben is az elméleti és gyakorlati munkák hiányára hívták fel a figyelmet. Jelen cikk a szabadidősporttal kíván foglalkozni, és célja, hogy bemutassa, milyen értéket teremt a szabadidősport az egyén, a vállalatok, a társadalom és a gazdaság számára, valamint azt, hogy az egyes szereplők a szabadidősport által milyen módon lehetnek versenyképesebbek. A szabadidősport és a versenyképesség rövid fogalmi definiálása után a szerző bemutatja az irodalom-feldolgozás és a 31 kvalitatív mélyinterjú kapcsolódó eredményeit. ___________________ Sport has always been an important part of society but it is now becoming an increasingly important part of the economy. The sport management literature mostly deals with competitive sport, leisure sport has a week position. Downward et al.have written about the lack of theoretical and empirical works in the area of leisure sport. This article deals with leisure sport, the aim of the author’s work is: to present the value creation of leisure sport for individuals, companies, for society and economy, and to examine how they could be more competitive through leisure sport. After presenting short definitions of leisure sport and competitiveness, the author does literature review and presents the most important thoughts of the articles and the results of my 31 qualitative in-depth interviews.

Különböző beszerzői magatartásminták a magyarországi kórházak körében (Behaviour of the Hungarian hospital in their relationship with drug suppliers.)

A szerzők kutatásának célja a magyar kórházak gyógyszerbeszállítókkal kapcsolatos magatartásának jobb megértése. A szervezeti viselkedés természetéből adódóan a szerzők kutatásukat a komplexitás paradigmájára támaszkodva (Mucchielli, 2004) végezték el. Ahhoz, hogy kórházak beszerzési döntéseinek komplex eljárásait megvizsgálják, egy vegyes kutatási módszer alkalmazására volt szükség. Elméleti háttérként az üzleti kapcsolatok értékének integrált modelljét alkalmazták. A tanulmányban bemutatják egy kvantitatív és egy kvalitatív kutatás eredményeit a magyarországi kórházak és a gyógyszerbeszállítók közötti üzleti kapcsolatokban. ________________ The main goal of this research is to better understand the behaviour of the Hungarian hospital in their relationship with drug suppliers. The nature of the organisational behaviour guides the authors to conduct their research on the complexity paradigm (Mucchielli, 2004). To be able to explore the complex procedure of purchasing decisions in the hospitals, they applied a research design based on mixed method research. As a theoretical background the authors used the integrated model of business relationship value. In their paper they introduce the results of a quantitative and a qualitative research about the business relationships between hospitals and drug suppliers in Hungary.
