The relationship between transformational leadership and innovative behaviour in a healthcare context:a team learning versus a cohesion perspective

The purpose of this study was to explore whether the relationship between transformational leadership and innovative behaviour is explained via the mediating role of team learning, or whether instead team cohesion mediates this relationship. Using survey data from 158 professionals within 21 teams in the Dutch healthcare context, we tested by means of hierarchical regression analyses: (a) the relationship between transformational leadership and innovative behaviour; (b) whether team learning or cohesion mediates this relationship; and (c) the relationship between team learning and cohesion, in relation to transformational leadership. Results showed that transformational leadership is positively related to innovative behaviour and that both cohesion and team learning mediate this relationship, with team learning being the strongest mediator. Addressing a neglected area, our study provides evidence to show that managers who enhance team learning are likely to maximise employees' scope for engaging in innovative behaviours. © 2012 Inderscience Enterprises Ltd.

Causal relationship between HRM policies and organisational performance:evidence from the Greek manufacturing sector

Blending insights from the contingency theory, the resource-based view, and the AMO theory, the purpose of this paper is to investigate the HRM-performance causal relationship in the Greek context. The empirical research is based on a sample of 178 organisations operating in the Greek manufacturing sector. Using structural equation modelling the results of the study revealed that the ability to perform (resourcing and development), motivation to perform (compensation and incentives), and opportunity to perform (involvement and job design) HRM policy domains are moderated by business strategies (cost, quality, innovation), and additionally, the motivation to perform is further moderated by managerial style and organisational culture. Further, the results indicate that the impact of HRM policies on organisational performance is fully mediated by employee skills, attitudes, and behaviour. The paper concludes that although the motivation to perform HRM policy domain causes organisational performance, through employee attitudes, it may be supported that organisational performance positively moderates the effectiveness of this HRM policy domain, raising thus the question of reverse causality.

Attitudes towards emotional expression mediate the relationship between childhood invalidation and adult eating concern

Previous research has suggested that invalidating childhood environments are positively related to the symptoms of eating disorders. However, it is unclear how childhood environments might impact upon the development of eating disorder symptoms. This study examined the relationship between parental invalidation and eating disorder-related attitudes in a nonclinical sample and tested the mediating effect of attitudes towards emotional expression. Two hundred women, with a mean age of 21 years, completed measures of invalidating childhood environments, attitudes towards emotional expression, and eating pathology. Eating concerns were positively associated with recollections of an invalidating parental environment. The belief that the expression of emotions is a sign of weakness fully mediated the relationship between childhood maternal invalidation and adult eating concern. Following replication and extension to a clinical sample, these results suggest that targeting the individual's attitude towards emotional expression might reduce eating attitudes among women who have experienced an invalidating childhood environment. © 2012 John Wiley & Sons, Ltd and Eating Disorders Association.

An empirical examination of the strategic decision-making process:the relationship between context, process, and outcomes

Despite concerted academic interest in the strategic decision-making process (SDMP) since the 1980s, a coherent body of theory capable of guiding practice has not materialised. This is because many prior studies focus only on a single process characteristic, often rationality or comprehensiveness, and have paid insufficient attention to context. To further develop theory, research is required which examines: (i) the influence of context from multiple theoretical perspectives (e.g. upper echelons, environmental determinism); (ii) different process characteristics from both synoptic formal (e.g. rationality) and political incremental (e.g. politics) perspectives, and; (iii) the effects of context and process characteristics on a range of SDMP outcomes. Using data from 30 interviews and 357 questionnaires, this thesis addresses several opportunities for theory development by testing an integrative model which incorporates: (i) five SDMP characteristics representing both synoptic formal (procedural rationality, comprehensiveness, and behavioural integration) and political incremental (intuition, and political behaviour) perspectives; (ii) four SDMP outcome variables—strategic decision (SD) quality, implementation success, commitment, and SD speed, and; (iii) contextual variables from the four theoretical perspectives—upper echelons, SD-specific characteristics, environmental determinism, and firm characteristics. The present study makes several substantial and original contributions to knowledge. First, it provides empirical evidence of the contextual boundary conditions under which intuition and political behaviour positively influence SDMP outcomes. Second, it establishes the predominance of the upper echelons perspective; with TMT variables explaining significantly more variance in SDMP characteristics than SD specific characteristics, the external environment, and firm characteristics. A newly developed measure of top management team expertise also demonstrates highly significant direct and indirect effects on the SDMP. Finally, it is evident that SDMP characteristics and contextual variables influence a number of SDMP outcomes, not just overall SD quality, but also implementation success, commitment, and SD speed.

Relationship between freight accessibility and logistics employment in US counties

This paper analyzes the relationship between freight accessibility and logistics employment in the US. It develops an accessibility measure relevant for logistics companies based on a gravity model. This allows for an analysis of the accessibility of US counties focusing on four different modes of transportation: road, rail, air, and maritime. Using a Partial Least Squares model, these four different freight accessibility measures are combined into two constructs, continental and intercontinental freight accessibility, and related to logistics employment. Results show that highly accessible counties attract more logistics employment than other counties. The analyses show that it is very important to control for the effect of the county population on both freight accessibility and logistics employment. While county population explains the most variation in the logistics employment per county, there is a significant relationship between freight accessibility and logistics employment, when controlling for this effect.

The relationship between spoken language and speech and nonspeech processing in children with autism:a magnetic event-related field study

It has been proposed that language impairments in children with Autism Spectrum Disorders (ASD) stem from atypical neural processing of speech and/or nonspeech sounds. However, the strength of this proposal is compromised by the unreliable outcomes of previous studies of speech and nonspeech processing in ASD. The aim of this study was to determine whether there was an association between poor spoken language and atypical event-related field (ERF) responses to speech and nonspeech sounds in children with ASD (n = 14) and controls (n = 18). Data from this developmental population (ages 6-14) were analysed using a novel combination of methods to maximize the reliability of our findings while taking into consideration the heterogeneity of the ASD population. The results showed that poor spoken language scores were associated with atypical left hemisphere brain responses (200 to 400 ms) to both speech and nonspeech in the ASD group. These data support the idea that some children with ASD may have an immature auditory cortex that affects their ability to process both speech and nonspeech sounds. Their poor speech processing may impair their ability to process the speech of other people, and hence reduce their ability to learn the phonology, syntax, and semantics of their native language.

On the relationship between cultural diversity and creativity in education:the moderating role of communal versus divisional mindset

We conducted an experimental study with the aim of testing certain conditions under which engaging with cultural diversity increases creativity among schoolchildren. Results obtained from a sample of 149 Italian elementary schoolchildren revealed that engaging with cultural diversity, operationalized by asking Italian children to work with immigrant children on a cooperative task, led to an increase in creativity. Furthermore, we found that this effect was only present when a communal but not a divisional mindset (emphasizing group distinctions) was present. We discuss theoretical and practical implications of findings.

The role of enduring involvement in the relationship between reference price and price acceptance in the context of multichannel choice

Understanding online price acceptance and its determining factors can be essential if the companies try to manage different type of channels. The paper aimed to reveal the role of enduring involvement in price acceptance in a multichannel (online and offline) context. The study revealed that the hedonic value of shopping can increase the negative intention of price acceptance in the online channel, but also explored that for the segment without shopping motivations a similar price level can be applied both in the online and in the offline environment.

A szervezeti elkötelezettség és a munka-család viszonyrendszer összefüggései (The relationship between organizational commitment and work-life balance)

376 ügyfélszolgálati dolgozó bevonásával végzett kérdőíves vizsgálatukban a szerzők arra keresték a választ, hogy a szervezeti elkötelezettség profilok hogyan függnek össze a munkahelyi elégedettséggel, a kilépési szándékkal és a munka-család viszonyrendszerre vonatkozó változókkal (munka-család konfliktus, munkacsalád egyensúly, munka-család gazdagítás). Nyolc különböző profilt találtak, amelyek elemzéséből kiderült: az elkötelezettség-komponensek közül az érzelmi elkötelezettségnek kitüntetett szerepe van a kedvező következményeket tekintve, továbbá az elkötelezettségkomponensek együttes hatása szinergikus lehet. ________ In their research that was based on the answers of 376 customer service employees to a questionnaire survey, the authors are looking at the relationship between the organizational commitment profiles and work satisfaction, intention to leave the organization and various subconcepts of work life balance (work-family conflict, work-family balance and work-family enrichment). They have found 8 different profiles, the analysis of which revealed the central role of the affective component regarding the positive outcomes of the above mentioned variables as well as the synergic relations among the different components of organizational commitment.

Comparative analysis of the relationship between phenological phenomena and meteorological indicators based on insect and plant monitoring

Climate change is one of the biggest environmental problems of the 21st century. The most sensitive indicators of the effects of the climatic changes are phenological processes of the biota. The effects of climate change which were observed the earliest are the remarkable changes in the phenology (i.e. the timing of the phenophases) of the plants and animals, which have been systematically monitored later. In our research we searched for the answer: which meteorological factors show the strongest statistical relationships with phenological phenomena based on some chosen plant and insect species (in case of which large phenological databases are available). Our study was based on two large databases: one of them is the Lepidoptera database of the Hungarian Plant Protection and Forestry Light Trap Network, the other one is the Geophytes Phenology Database of the Botanical Garden of Eötvös Loránd University. In the case of butterflies, statistically defined phenological dates were determined based on the daily collection data, while in the case of plants, observation data on blooming were available. The same meteorological indicators were applied for both groups in our study. On the basis of the data series, analyses of correlation were carried out and a new indicator, the so-called G index was introduced, summing up the number of correlations which were found to be significant on the different levels of significance. In our present study we compare the significant meteorological factors and analyse the differences based on the correlation data on plants and butterflies. Data on butterflies are much more varied regarding the effectiveness of the meteorological factors.

A tranzakciós költségek és a szabványosítás kapcsolata (Relationship between transaction costs and standardization)

Az elmúlt néhány évtizedben a szabványosítás terén igen komoly változások mentek végbe. Ugrásszerűen megnőtt a szabványok száma, és jelentősen átalakult a szabványosítás folyamata is. Ezzel párhuzamosan a téma gazdasági hatásaival foglalkozó kutatások száma is megsokszorozódott, ami elsősorban a hálózati externáliák irodalmának robbanásszerű gyarapodásának köszönhető. Jelen tanulmány – az elméletek fősodrától eltérően – a tranzakciós költségek elméletében (TKE) helyezi el a szabványosítást. A szabványok és a tranzakciós költségek kapcsolatáról már születtek korábban is tanulmányok, de ezek a szabványoknak a tranzakciós költségekre gyakorolt hatásaira fókuszáltak. A tanulmány ezzel szemben arra helyezi a hangsúlyt, hogy azonosítsa a tranzakciós költségeknek a szabványosításra gyakorolt hatásait. A kutatás célja, hogy olyan elméleti alapot adjon, amelyben a témakör átfogóan elemezhető. A fő kutatási kérdés az, hogy mitől függ az, hogy melyik mechanizmus kereteiben érdemes a szabványosítást lebonyolítani. ________ Significant changes have characterized the last few decades of standardization. The number of standards has dramatically increased and processes of standardization have also changed a lot. At the same time the amount of researches that are concerned with the economic impact of standardization has also multiplied due to the boom in the literature of network externalities. Unlike the mainstream, this paper places standardization in the theory of transaction cost economics. Although there are earlier papers that are concerned with the relationship between standards and transaction costs, these studies focus on the impact of standards on transaction costs. In contrast, this paper lays emphasis on the identification of the impact of transaction costs on standardization. This study aims to provide a theoretical basis for the comprehensive analyses. The main research question: What determines which coordination mechanism is used to evolve a standard?

"Rentier States" or the Relationship between Regime Stability and Exercising Power in Post-Soviet Central Asia

The paper intends to give an insight into the relations of the economic and political systems of the Central Asian republics using the theoretical framework of the "rentier economy" and "rentier state" approach. The main findings of the paper are that two (Kazakhstan and Turkmenistan) of the five states examined are commodity export dependent “full-scale” rentier states. The two political systems are of a stable neo-patrimonial regime character, while the Kyrgyz Republic and Tajikistan, poor in natural resources but dependent on external rents, may be described as "semi-rentier" states or "rentier economies". They are politically more instable, but have an altogether authoritarian, oligarchical “clan-based” character. Uzbekistan with its closed economy, showing tendencies of economic autarchy, is also a potentially politically unstable clan-based regime. Thus, in the Central Asian context, the rentier state or rentier economy character affects the political stability of the actual regimes rather than having a direct impact on whether power is exercised in an autocratic or democratic way.
