Testing the Nursing Worklife Model in Canada and Australia: A multi-group comparison study

© 2014 Elsevier Ltd. Study aim: To test a model derived from the Nursing Worklife Model linking elements of supportive practice environments to nurses' turnover intentions and behaviours in Canada and Australia. Background: With the worldwide shortage of nurses, retaining nurses within fiscally challenged health care systems is critical to sustaining the future of the nursing workforce and ultimately safe patient care. The Nursing Worklife Model describes a pattern of relationships amongst environmental factors that support nursing practice and link to nurse turnover. This model has been tested in north American settings but not in other countries. Methods: A secondary analysis of data collected in two cross-sectional studies in Canadian and Australian hospitals ( N= 4816) was conducted to test our theoretical model. Multigroup structural equation modelling techniques were used to determine the validity of our model in both countries and to identify differences between countries. Results: The hypothesized model relationships were supported in both countries with few differences between groups. Components of supportive professional practice work environments, particularly resources, were significantly linked to nurses' turnover intentions and active search for new jobs. Leadership played a critical role in shaping the pattern of relationships to other components of supportive practice environments and ultimately turnover behaviours. Conclusion: The Nursing Worklife Model was shown to be valid in both countries, suggesting that management efforts to ensure that features of supportive practice environments are in place to promote the retention of valuable nursing resources

Extended moment formation and magnetic ordering in the trigonal chain compound Ca3Co2O6

The results of electronic structure calculations for the one-dimensional magnetic chain compound Ca3Co2O6 are presented. The calculations are based on density functional theory and the local density approximation and used the augmented spherical wave (ASW) method. Our results allow for deeper understanding of recent experimental findings. In particular, alternation of Co 3d low- and high-spin states along the characteristic chains is related to differences in the oxygen coordination at the inequivalent cobalt sites. Strong hybridization of the d states with the O 2p states lays ground for polarization of the latter and the formation of extended localized magnetic moments centered at the high-spin sites. In contrast, strong metal-metal overlap along the chains gives rise to intrachain ferromagnetic exchange coupling of the extended moments via the d_{3z^2-r^2} orbitals of the low-spin cobalt atoms.Comment: 10 pages, 4 figures more information at http://www.physik.uni-augsburg.de/~eyert

Phosphatidylinositol-4,5 Bisphosphate Produced by PIP5K(gamma) Regulates Gelsolin, Actin Assembly, and Adhesion Strength of N-Cadherin Junctions

Phosphoinositides regulate several actin-binding proteins but their role at intercellular adhesions has not been defined. We found that phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) was generated at sites of N-cadherin–mediated intercellular adhesion and was a critical regulator of intercellular adhesion strength. Immunostaining for PI(4,5)P2 or transfection with GFP-PH-PLCδ showed that PI(4,5)P2 was enriched at sites of N-cadherin adhesions and this enrichment required activated Rac1. Isoform-specific immunostaining for type I phosphatidylinositol 4-phosphate 5 kinase (PIP5KI) showed that PIP5KIγ was spatially associated with N-cadherin–Fc beads. Association of PIP5KIγ with N-cadherin adhesions was in part dependent on the activation of RhoA. Transfection with catalytically inactive PIP5KIγ blocked the enrichment of PI(4,5)P2 around beads. Catalytically inactive PIP5KIγ or a cell-permeant peptide that mimics and competes for the PI(4,5)P2-binding region of the actin-binding protein gelsolin inhibited incorporation of actin monomers in response to N-cadherin ligation and reduced intercellular adhesion strength by more than twofold. Gelsolin null fibroblasts transfected with a gelsolin severing mutant containing an intact PI(4,5)P2 binding region, demonstrated intercellular adhesion strength similar to wild-type transfected controls. We conclude that PIP5KIγ-mediated generation of PI(4,5)P2 at sites of N-cadherin contacts regulates intercellular adhesion strength, an effect due in part to PI(4,5)P2-mediated regulation of gelsolin

Empowerment, stress vulnerability and burnout among portuguese nursing staff

The work environment in Portuguese hospitals, characterized by economic cutbacks, can lead to higher levels of burnout experienced by nursing staff. Furthermore, vulnerability to stress can negatively affect the perception of burnout in the workplace. However, structural empowerment is an organizational process that can prevent and decrease burnout among nurses. Consequently, the aim of the study was to examine to what extent structural empowerment and vulnerability to stress can play a predictive role in core burnout in a sample of Portuguese nurses. A convenience sample of 297 nursing staff members from Portuguese hospitals was used in this study. Core burnout was negatively and significantly related to all the dimensions of structural empowerment, and it was positively and significantly related to vulnerability to stress. Regression models showed that core burnout was significantly predicted by access to funds, access to opportunities and vulnerability to stress. Organizational administrations must make every effort in designing interventions focused on structural empowerment, as well as interventions focused on individual interventions that enhance skills for coping with stress.info:eu-repo/semantics/publishedVersio

Looking ‘beyond the factory gates’:towards more pluralist and radical approaches to intra-organizational trust research

The aim of this paper is to suggest new avenues for trust research by critiquing the extant literature on this topic. We analyze the most influential research on intra-organizational trust from the perspective of a classic industrial sociology framework from the 1970s – Alan Fox’s work on frames of reference and trust dynamics. Our analysis of intra-organizational trust studies leads us to three conclusions. Firstly, the large majority of intra-organizational trust research has strong unitarist underpinnings, which support a managerial agenda that is potentially detrimental to employees’ and (indeed managers’) long-term interests. Secondly, most of this research fails to explain how trust in organizations is embedded in societal and field level institutions, hence it would benefit from looking ‘beyond the factory gates’ for a more complete understanding of trust dynamics in organizations. In this connection, we argue that Fox’s pluralist and radical perspectives, which are under-represented in intra-organizational trust research, could provide new lines of inquiry by locating internal trust relations in a wider institutional context. Thirdly, Fox’s explanation of how low and high trust dynamics in organizations are embedded in wider society may help address the concerns about under-socialized, endogenous explanations and open the way for structure-agency analyses of building, maintaining and repairing intra-organizational trust

Magnetic ordering in trigonal chain compounds

We present electronic structure calculations for the one-dimensional magnetic chain compounds Ca_3CoRhO_6 and Ca_3FeRhO_6. The calculations are based on density functional theory and the local density approximation. We use the augmented spherical wave (ASW) method. The observed alternation of low- and high-spin states along the Co-Rh and Fe-Rh chains is related to differences in the oxygen coordination of the transition metal sites. Due to strong hybridization the O 2p states are polarized, giving rise to extended localized magnetic moments centered at the high-spin sites. Strong metal-metal overlap along the chains leads to a substantial contribution of the low-spin Rh 4d_{3z^2-r^2} orbitals to the exchange coupling of the extended moments. Interestingly, this mechanism holds for both compounds, even though the coupling is ferromagnetic for the cobalt and antiferromagnetic for the iron compound. However, our results allow to understand the different types of coupling from the filling dependence of the electronic properties.Comment: 8 pages, 3 figures, more information at http://www.physik.uni-augsburg.de/~eyert

Building resilience in contemporary nursing practice

YesThe nursing profession is being threatened by staff shortages. Catherine Best explains why building resilience from within the profession is vital to safeguarding its future, by keeping newly qualified nurses in the job and preventing emotional ‘burnout’ across disciplines Resilience in nursing has been critiqued and challenged throughout the nursing literature. Trends in nursing have led to many nurses leaving the profession early in their career, often due to the immense pressures that they work under. There are many opinions on how nurses can develop the resilience needed to maintain professional integrity and continue to provide safe and effective care, while attempting to shoulder the considerable impact of political and professional drivers. This not only leaves nurses exhausted but often without hope. By taking collective action, this article argues that nurses may benefit from sharing ideas and learning from others, and in so doing rekindle hope and a belief that things can change
