Cooperative bank efficiency in Japan: a parametric distance function analysis

This study examines the relative performance of Japanese cooperative banks between 1998 and 2009, explicitly modeling non-performing loans as an undesirable output. Three key findings emerge. First, the sector is characterized by increasing returns to scale which supports the ongoing amalgamation process within the sector. Second, although restricted in product offerings, markets and their membership base, Japanese cooperatives secured both technical progress (a positive shift in the frontier) and a decrease in technical inefficiency (distance from the frontier). Third, the analysis highlighted that regulatory pressure to reduce non-performing loans will have an adverse impact on both output and performance. 

The distribution of arsenic in the body tissues of wood mice and bank voles

Arsenic is accumulated by free-living small mammals, but there is little information on the resultant concentrations in different tissues other than liver and kidney. Such information is important because the severity of toxicological effects may be related to the amount of arsenic accumulated in specific organs, and the availability of arsenic to predators is, in part, dependent on which tissues accumulate arsenic. The objective of this study was to quantify the arsenic concentrations and the percentage of the total body burden (%TBB) accumulated in different body tissues of free-living small mammals and to determine how these factors varied with severity of habitat contamination. Arsenic concentrations were measured in various tissues of wood mice (Apodemus sylvaticus) and bank voles (Clethrionomys glareolus) from a range of arsenic-contaminated sites in southwest Britain. Arsenic concentrations in the gastrointestinal (GI) tract (including contents), liver, kidneys, spleen, lung, femur, and fur of both species varied significantly between sites and were higher in mice and voles from heavily contaminated areas. Heart and brain arsenic concentrations did not vary with degree of environmental contamination. The GI tract and excised carcass contained roughly equal amounts of arsenic and, in sum, comprised 75-85% of the TBB on uncontaminated sites and 90-99% on contaminated sites. Although the excised carcass contains about half of the TBB, its importance in food-chain transfer of arsenic to predators may depend on the bioavailability of arsenic sequestered in fur. In contrast, the GI tract and its contents, provided that it is consumed, will always be a major transfer pathway for arsenic to predators, regardless of the severity of habitat contamination.

Arsenic contamination in wood mice (Apodemus sylvaticus) and bank voles (Clethrionomys glareolus) on abandoned mine sites in southwest Britain

Arsenic can be highly toxic to mammals but there is relatively little information on its transfer to and uptake by free-living small mammals. The aim of this study was to determine whether intake and accumulation of arsenic by wild rodents living in arsenic-contaminated habitats reflected environmental levels of contamination and varied between species, sexes and age classes. Arsenic concentrations were measured in soil, litter, wood mice (Apodemus sylvaticus) and bank voles (Clethrionomys glareolus) from six sites which varied in the extent to which they were contaminated. Arsenic residues on the most contaminated sites were three and two orders of magnitude above background in soil and litter, respectively. Arsenic concentrations in the stomach contents, liver, kidney and whole body of small mammals reflected inter-site differences in environmental contamination. Wood mice and bank voles on the same sites had similar concentrations of arsenic in their stomach contents and accumulated comparable residues in the liver, kidney and whole body. Female bank voles, but not wood mice, had significantly higher stomach content and liver arsenic concentrations than males. Arsenic concentration in the stomach contents and body tissues did not vary with age class. The bioaccumulation factor (ratio of arsenic concentration in whole body to that in the diet) in wood mice was not significantly different to that in bank voles and was 0.69 for the two species combined, indicating that arsenic was not bioconcentrated in these rodents. Overall, this study has demonstrated that adult and juvenile wood mice and bank voles are exposed to and accumulate similar amounts of arsenic on arsenic-contaminated mine sites and that the extent of accumulation depends upon the level of habitat contamination.

Patterning employee voice in multinational companies

Employee voice has been an enduring theme within the employment relations literature.This article profiles the incidence of a range of direct and indirect employee voice mechanisms within multinational companies (MNCs) and, using an analytical framework, identifies a number of different approaches to employee voice. Drawing from a highly representative sample of MNCs in Ireland, we point to quite a significant level of engagement with all types of employee voice, both direct and indirect. Using the analytical framework, we find that the most common approach to employee voice was an indirect voice approach (i.e. the use of trade unions and/or non-union structures of collective employee representation). The regression analysis identifies factors such as country of origin, sector, the European Union Directive on Information and Consultation and date of establishment as having varying impacts on the approaches adopted by MNCs to employee voice. © The Author(s) 2010.

The determinants of financial participation schemes within multinational companies in Ireland

Using a survey of multinational companies (MNCs), we investigate the factors that determine the use and scope of financial participation in MNCs operating in Ireland. We explore the impact of six factors - country of origin, age, employment size (Irish and worldwide employment size), ownership structure, trade union recognition and sector. Descriptive results find that financial participation schemes are quite common within MNCs in Ireland. Many of these schemes are only available to higher levels of staff. Multivariate analysis reveals that five out of the six factors (the exception was sector) had varying impacts on financial participation schemes. © 2012 Copyright Taylor and Francis Group, LLC.

Learning transfer in multinational companies:Explaining inter-organisation variation

This article addresses the extent to which multinational companies (MNCs) in Ireland deploy practices aimed at the transfer of learning in their operations and the factors explaining inter-organisation variation in so doing. Using data from 260 MNCs, we find that comparatively large numbers of firms deploy practices to transfer learning in their Irish operations. Most notably, we find that almost half of all MNCs have a formal policy on organisational learning, while more than six in every ten MNCs in Ireland utilise three or more learning transfer mechanisms. In investigating inter-organisation variation with respect to these, we test a number of hypotheses involving nationality, sectoral, MNC (e.g. organisation structure) and HR factors. Our results show that the presence of international HR structures is a significant factor in explaining learning transfer in MNCs. We also find support that employment size, sector and integration between the MNC's global operations are useful variables in explaining variation in the deployment of practices on learning transfer in MNCs. © 2009 Blackwell Publishing Ltd.

The making of a void sovereignty: political implications of the military checkpoints in the West Bank

Research on the Israeli checkpoints in the West Bank has emphasized not only that these checkpoints have dire implications for the Palestinians living there, at the personal, familial, and communal levels, and devastating eff ects on the Palestinian economy, but also that they have far-reaching consequences for the ability of the Palestinians to establish an independent political entity. At the same time, analysis of the Israeli forms of domination over the Palestinians has also stressed the role of a Palestinian governing authority in sustaining the Israeli rule, since the former relieves the latter of its responsibility to care for the occupied Palestinian population. This paper aims to address this apparent contradiction claiming that a comprehensive analysis of Israeli forms of domination requires a spatial examination of the operation of sovereignty with an assessment of governmentalizing arrays. This combined analysis suggests that a Palestinian sovereignty, but one which is emptied of its actual ruling power, is construed at the checkpoints as an epiphenomenon of Israeli apparatuses of control. © 2013 Pion and its Licensors.
