This article examines the work and roles of HR managers in the Irish recession. It tests the validity of three competing views about the future of HR: that the profession needs to become a business partner; that it is knee-deep in a legitimacy crisis; and that it is fragmenting by being unable to cope with the complexity of modern organizational life. Three key findings emerge from the research. First, HR managers have gained greater influence in business decision-making, but much of this influence arises from short-run retrenchment measures. Second, many HR managers remain committed to long established professional values and ideas of good practice. Third, modern HR managers are developing a professional identity that allows them to perform multiple, competing roles. These findings challenge existing arguments about the effects of the current recession. They also speak to ongoing debates about changing HR roles by showing how HR managers remain adept at making pragmatic adaptations to secure their role in organizational life. © The Author(s) 2012.

In reconstructive surgery, skeletal muscle may endure protracted ischemia before reperfusion, which can lead to significant ischemia/reperfusion injury. Ischemic postconditioning induced by brief cycles of reperfusion/reocclusion at the end of ischemia has been shown to salvage skeletal muscle from ischemia/reperfusion injury in several animal models. However, ischemic postconditioning has not been confirmed in human skeletal muscle. Using an established in vitro human skeletal muscle hypoxic conditioning model, we tested our hypothesis that hypoxic postconditioning salvages ex vivo human skeletal muscle from hypoxia/reoxygenation injury and the mechanism involves inhibition of opening of the mitochondrial permeability transition pore (mPTP) and preservation of ATP synthesis. Muscle strips (~0.5×0.5×15mm) from human rectus abdominis muscle biopsies were cultured in Krebs-Henseleit-HEPES buffer, bubbled with 95%N(2)/5%CO(2) (hypoxia) or 95%O(2)/5%CO(2) (reoxygenation). Samples were subjected to 3h hypoxia/2h reoxygenation. Hypoxic postconditioning was induced by one or two cycles of 5min reoxygenation/5min hypoxia after 3h hypoxia. Muscle injury, viability and ATP synthesis after 2h of reoxygenation were assessed by measuring lactate dehydrogenase (LDH) release, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) reduction and ATP content, respectively. Hypoxic postconditioning or treatment with the mPTP-opening inhibitors Cyclosporine A (CsA, 5×10(-6)M) or N-Methyl-4-isoleucine Cyclosporine (NIM811, 5×10(-6)M) 10min before reoxygenation decreased LDH release, increased MTT reduction and increased muscle ATP content (n=7 patients; P

Ireland provides an interesting case study of the distributional consequences of the Great Recession. To explore such effects we develop a measure of economic vulnerability based on a multidimensional risk profile for income poverty, material deprivation and economic stress. In the context of conflicting expectations of trends in social class differentials, we provide a comparison of pre and post-recession periods. Our analysis reveals a doubling of levels of economic vulnerability and a significant change in multidimensional profiles. Income poverty became less closely associated with material deprivation and economic stress and the degree of polarization between vulnerable and non-vulnerable classes was significantly reduced. Economic vulnerability is highly stratified by social class for both pre and post-recession periods. Focusing on absolute change, the main contrast is between the salariat and the non-agricultural self-employed and the remaining classes; providing some support for notions of polarization. In terms of relative change the higher salariat, the non-agricultural self-employed, the semi-unskilled manual and those who never worked gained relative to the remaining classes. This provides support the notion of ‘middle class squeeze’. The changing relationship between social class and household work intensity reflected a similar pattern. The impact of the latter on economic vulnerability declined sharply, while it came to play an increasing role in mediating the impact of membership of the non-agricultural middle classes. Responding to the political pressures likely to be associated with ‘middle class squeeze’ while sustaining the social welfare arrangements that have traditionally protected the economically vulnerable presents formidable challenges in terms of maintaining social cohesion and political legitimacy.

The time period bridging the years 2007 to 2012 will be remembered as one characterised by dramatic changes in the Irish and UK construction industries. Construction companies witnessed unprecedented changes in the environment, namely the coincidence of a sharp economic downturn, the significant decline of public works, a reduction in lending, increased competition, and structural changes in the marketplace. Nevertheless, little has been documented on what response strategies construction companies adopt as a result of an economic recession. Based on four exploratory case studies, a taxonomy framework of the response strategies adopted by Irish and UK construction companies during the 2007 economic recession was developed relative to Porter’s (1980) generic strategies of cost leadership, differentiation, and focus. Porter’s model (1980) is a well known theoretical framework among business strategists and industrial economists worldwide. The analysis provides strong support for the adoption of cost leadership strategies as a means to surviving the 2007 economic recession. The case studies further suggest that cost control initiatives are one of the most important attributes in companies’ responses to the 2007 recession. The findings provide valuable assistance for construction contractors in developing effective strategies and thus reducing business failures during recessionary periods.

The purpose of this paper is to identify best practice construction dispute resolution in small-to-medium enterprises (SMEs) within Ireland during the recent economic recession. A sequential mixed methodology encompassing a detailed literature review, case studies, and questionnaire survey is adopted, with results analyzed using both exploratory (data reduction) and confirmatory (structural equation modelling) factor analysis. The results show that four core aspects should be adopted by SMEs to achieve best practice construction dispute resolution in recession: third-party intervention, adoption of a streamlined process, proactive party characteristics, and the use of legal professionals. Numerous studies of this subject have been conducted; however, no research has been done to date documenting best practice in construction dispute resolution within SMEs, particularly in light of the economic recession in Ireland. It is clear that dispute resolution in Ireland is currently undergoing fundamental changes, and time is necessary to see if the new Construction Contracts Act 2013 will help this practice. Therefore, it is a fundamental requirement for project management and legal professionals to acknowledge the changing environment attributable to the economic downturn and the resultant SME best practices in dispute resolution. This paper fulfills a gap in knowledge with the emergence of the economic recession and the evolution of best practice in dispute resolution within SMEs in the Irish construction sector.

Since 2008, Ireland has experienced the most severe economic and labour market crisis since the foundation of the State. These economic and labour market changes have had a stark impact on the standard of living across the Irish population. The rapid deterioration in the labour market, the rising level of household indebtedness and stringent austerity measures to plug the public finance deficit have had a widespread impact yet there is debate about where the heaviest burden has fallen and where the economic stress has been felt most. The paper analyses data from the Survey of Income and Living Conditions for the period 2004 to 2011. The aim of the paper is to develop and test a measure of economic stress, which will capture some of the aspects of the rapid change in economic fortunes on Irish households that are not picked up by income alone. This includes tapping into features of the recession such as debt problems, unsustainable housing costs, and other difficulties associated with managing on reduced household income in a period of uncertainty. In testing such a measure we examine trends over time from boom to bust in the Irish economy and consider how economic stress is distributed across different socio-economic groups. The paper explores the distribution and level of economic stress across income class groups, social classes and the life-course and tests the thesis of ‘middle class squeeze’.
