Organizational climate and climate strengths in UK hospitals

In recent years, researchers have paid increasing attention to the idea of “climate strength”—the level of agreement about climate within a work group or organization. However, at present the literature is unclear about the extent to which climate strength is a positive attribute, and is concerned predominantly with small teams or organizational units. This article considers three theoretical perspectives of climate strength, and extends these to the organizational level. These three roles of climate strength were tested in 56 hospitals in the United Kingdom. Positive relationships were discovered between two of three climate dimensions (Quality and Integration) and expert ratings of organizational performance, and a curvilinear effect between Integration climate strength and performance was also found. Very high or very low Integration climate strength was less beneficial than a moderate level of climate strength. However, there were no interaction effects discovered between climate and climate strength. Implications for future climate strength research are discussed.

Positive psychology approaches to public services leadership: An introduction to strengths-based leadership

To readers of the popular press, the words ‘positive psychology’ may conjure up images of happiness gurus and people having their feet massaged, their heads resting peacefully on pink, fluffy clouds. But in this article, our aim is to demonstrate how the new science of positive psychology speaks powerfully to - and has much to contribute to - the development of leadership and the practices and processes of organisations, whether in the public or private sectors. Much of our work is concerned with the applications of this new field, and particularly with building strengths-based organisations. A key pillar of this work is around enabling strengths-based leadership, and provides our focus for this article.

Attentional processes link perception and action

Behavioural studies on normal and brain-damaged individuals provide convincing evidence that the perception of objects results in the generation of both visual and motor signals in the brain, irrespective of whether or not there is an intention to act upon the object. In this paper we sought to determine the basis of the motor signals generated by visual objects. By examining how the properties of an object affect an observer's reaction time for judging its orientation, we provide evidence to indicate that directed visual attention is responsible for the automatic generation of motor signals associated with the spatial characteristics of perceived objects.

The missing link:Analogous human and primate cortical gamma oscillations

Recent animal studies highlighting the relationship between functional imaging signals and the underlying neuronal activity have revealed the potential capabilities of non-invasive methods. However, the valuable exchange of information between animal and human studies remains restricted by the limited evidence of direct physiological links between species. In this study we used magnetoencephalography (MEG) to investigate the occurrence of 30-70 Hz (gamma) oscillations in human visual cortex, induced by the presentation of visual stimuli of varying contrast. These oscillations, well described in the animal literature, were observed in retinotopically concordant locations of visual cortex and show striking similarity to those found in primate visual cortex using surgically implanted electrodes. The amplitude of the gamma oscillations increases linearly with stimulus contrast in strong correlation with the gamma oscillations found in the local field potential (LFP) of the macaque. We demonstrate that non-invasive magnetic field measurements of gamma oscillations in human visual cortex concur with invasive measures of activation in primate visual cortex, suggesting both a direct representation of underlying neuronal activity and a concurrence between human and primate cortical activity. © 2005 Elsevier Inc.

Skeletal muscle atrophy, a link between depression of protein synthesis and increase in degradation

Both proteolysis-inducing factor (PIF) and angiotensin II have been shown to produce a depression in protein synthesis in murine myotubes concomitant with an increased phosphorylation of eukaryotic initiation factor 2 (eIF2α). Both PIF and angiotensin II were shown to induce autophosphorylation of the RNA-dependent protein kinase (PKR), and an inhibitor of this enzyme completely attenuated the depression in protein synthesis and prevented the induction of eIF2α phosphorylation. The PKR inhibitor also completely attenuated the increase in protein degradation induced by PIF and angiotensin II and prevented the increase in proteasome expression and activity. To confirm these results myotubes were transfected with plasmids that express either wild-type PKR, or a catalytically inactive PKR variant, PKRΔ6. Myotubes expressing PKRΔ6 showed no increase in eIF2α phosphorylation in response to PIF or angiotensin II, no depression in protein synthesis, and no increase in protein degradation or increase in proteasome expression. Induction of the ubiquitin-proteasome pathway by PIF and angiotensin II has been linked to activation of the transcription factor nuclear factor-κB (NF-κB). Inhibition of PKR prevented nuclear migration of NF-κB in response to both PIF and angiotensin II, by preventing degradation of the inhibitor protein I-κB. Phosphorylation of PKR and eIF2α was also significantly increased in the gastrocnemius muscle of weight losing mice bearing the MAC16 tumor, suggesting that a similar process may be operative in cancer cachexia. These results provide a link between the depression of protein synthesis in skeletal muscle and the increase in protein degradation. © 2007 by The American Society for Biochemistry and Molecular Biology, Inc.

To link or not to link: a test of the case linkage principles using serial car theft data

The purpose of the present study is to test the case linkage principles of behavioural consistency and behavioural distinctiveness using serial vehicle theft data. Data from 386 solved vehicle thefts committed by 193 offenders were analysed using Jaccard's, regression and Receiver Operating Characteristic analyses to determine whether objectively observable aspects of crime scene behaviour could be used to distinguish crimes committed by the same offender from those committed by different offenders. The findings indicate that spatial behaviour, specifically the distance between theft locations and between dump locations, is a highly consistent and distinctive aspect of vehicle theft behaviour; thus, intercrime and interdump distance represent the most useful aspects of vehicle theft for the purpose of case linkage analysis. The findings have theoretical and practical implications for understanding of criminal behaviour and for the development of decision-support tools to assist police investigation and apprehension of serial vehicle theft offenders.

FDI, trade and growth, a causal link?

. FDI, Trade and Growth, a Causal Link? (RP0710) Prof Nigel DRIFFIELD Dr Rakesh BISSOONDEEAL Mayang Pramadhani Non-technical Summary This paper explores the relationship between imports, exports, foreign direct investment and growth. For some time there has been a good deal of debate whether trade and foreign direct investment) FDI are substitutes and complements, with the existing literature generating some rather contradictory findings. We show, for Indonesia that inward FDI and both imports and exports are complementary, and further that FDI causes an increase in trade. This is of particular interest for a country such as Indonesia, that has attracted a high proportion of export-orientated inward investment. This, theoretically at least is associated with an increase in imports, in the form of capital goods and components, but a reduction in imports. We show that the previous literature that fails to find such a relationship does so because both trade and FDI are associated with growth, and previous work ignores these growth effects when seeking to isolate the relationship between trade and FDI.

Third order intermodulation products generated on transmission through a nonlinear radio-on-fibre link

Two-tone intermodulation tests were simulated for an amplitude modulated radio-on-fibre link including fibre dispersion, nonlinearity and loss. The third-order intercept results are presented for varying fibre lengths and optical transmission powers.

Developmental anomalies of the eye: the genetic link

As in other areas of the body, developmental anomalies of the eye arise as a result of the disturbance of events during embryology and in a proportion of cases these anomalies are genetically inherited. Developmental anomalies that occur early in embryonic life may be so severe that the embryo may not survive but others result in the birth of healthy babies but with developmental eye defects of varying severity. The most dramatic developmental defects of the eye include anophthalmos (complete absence of an eye), microphthalmos (a general failure of the eye to develop resulting in a small, undeveloped eye), coloboma (caused by failure of the optic vesicle to invaginate), and aniridia (complete or partial loss of the iris). The present article does not provide an exhaustive review of the topic but considers the major types of developmental anomaly to affect the eye and will discuss how recent progress in genetics has increased our understanding of these disorders. The major genes linked to the developmental anomalies are discussed as well as how defects in these genes might lead to specific problems.

Export memory: a preliminary investigation of its quality, its use, and its link to export performance

Exporting is one of the main ways in which organizations internationalize. With the more turbulent, heterogeneous, sophisticated and less familiar export environment, the organizational learning ability of the exporting organization may become its only source of sustainable competitive advantage. However, achieving a competitive level of learning is not easy. Companies must be able to find ways to improve their learning capability by enhancing the different aspects of the learning process. One of these is export memory. Building from an export information processing framework this research work particularly focuses on the quality of export memory, its determinants, its subsequent use in decision-making, and its ultimate relationship with export performance. Within export memory use, four export memory use dimensions have been discovered: instrumental, conceptual, legitimizing and manipulating. Results from the qualitative study based on the data from a mail survey with 354 responses reveal that the development of export memory quality is positively related with quality of export information acquisition, the quality of export information interpretation, export coordination, and integration of the information into the organizational system. Several company and environmental factors have also been examined in terms of their relationship with export memory use. The two factors found to be significantly related to the extent of export memory use are acquisition of export information quality and export memory quality. The results reveal that export memory quality is positively related to the extent of export memory use which in turn was found to be positively related to export performance. Furthermore, results of the study show that there is only one aspect of export memory use that significantly affects export performance – the extent of export memory use. This finding could mean that there is no particular type of export memory use favored since the choice of the type of use is situation specific. Additional results reveal that environmental turbulence and export memory overload have moderating effects on the relationship between export memory use and export performance.

Pharmacy and public health: examining the link between strategy and practice

Despite having been described by the then (2003) Chief Pharmaceutical Officer for England as ·probably the biggest untapped resource for health improvement", the development of the public health function of community pharmacists has been limited. However, devolution of healthcare budgets has led 10 differential rates of development of the public health function in each administration of the UK (England, Scotland, Wales and Northern Ireland). This is measured and reflected upon in this thesis. Two large-scale surveys were conducted, one of key strategic personnel (Directors of Public Health and Chief Pharmacists) in Primary Care Organisations (PCOs) and one of practicing community pharmacists. This research highlights the fact that community pharmacists have developed an individualistic, service-based approach to their engagement with public health that is contrary to the more collective approach adopted by the wider public health movement. The study measures the scope and level of health-improving services through community pharmacy across the UK and shows that the nature of the pharmacy contractor (independent, multiple etc.) may impact on the range and nature of services provided. Survey data also suggest that attitudes towards pharmacy involvement in the public health agenda vary markedly between Directors of Public Health, PCO Chief Pharmacists, and community pharmacists. Furthermore, within the community pharmacist population, attitudes are affected by a wide range of factors including the nature of employment (owner, employee, self-employed) and the type of employing pharmacy (independent, multiple etc.). Implications for policy and areas for further research aimed at maximising the public health function of community pharmacists are suggested.
