Coordination, Efficiency and Two-Sided Cheap Talk

We consider the Battle of the Sexes game with incomplete information and allow two-sided cheap talk before the game is played. We characterise the set of fully revealing symmetric cheap talk equilibria. The best fully revealing symmetric cheap talk equilibrium, when exists, has a desirable characteristic. When the players' types are different, it fully coordinates on the ex-post efficient pure Nash equilibrium. We also analyse the mediated communication equilibria of the game. We find the range of the prior for which this desirable equilibrium exists under unmediated and mediated communication processes.

Do Foreign Greenfields Outperform Foreign Acquisitions or Vice Versa? An Institutional Perspective.

Prior studies of the comparative performance of greenfields and acquisitions have advanced competing arguments, with some arguing that greenfields should outperform acquisitions because acquisitions are costlier to integrate, and others that acquisitions should outperform greenfields because greenfields suffer from a liability of newness. Moreover, while the costs of integration and the liability of newness are at their greatest during a subsidiary's first years, prior studies have tested their competing arguments on samples containing older subsidiaries. We extend these prior studies by (1) developing an institutional theory-based framework that simultaneously considers the costs of integration and the liability of newness, (2) recognizing that both types of costs vary with the level of subsidiary integration, and (3) focusing on the stage of their life during which subsidiaries predominantly incur these costs. To measure subsidiary performance, we ask managers of Dutch multinationals how their ex ante performance expectations compare to the subsidiary's ex post performance during its first two years. Analysing a sample of 191 foreign subsidiaries and controlling for entry mode self-selection and other factors, we find that acquisitions outperform greenfields at low and intermediate levels of subsidiary integration, but that greenfields outperform acquisitions at higher integration levels.

Hospitalization in Geriatric Wards: Considerations on the Evaluation of the Outcome

Within a defined law framework, the Italian central health system dictates the standards for hospitalization to local care units, which are in turn allowed to establish their own effectiveness criteria. The appropriateness of the hospitalization decision is therefore predetermined at patients admission, whereas its effectiveness relies on the ex post patient well-being as a result of the complex system of reciprocal relations between patients and healthcare agents at the ward level. We consider the outcomes in geriatric wards referring to the national health system, with respect both to patients traits at the individual level and wards/hospital settings. The risk that models the healthcare outcome is accordingly adjusted for covariates at the different levels of analysis (Goldstein & Spiegelhalter, 1996), thus allowing to differentiate among outcomes in terms of the hospitalization structure and, when appropriate, of territorial aggregation.

Resistance, transition and exclusion: Politically motivated ex-prisoners and conflict transformation in Northern Ireland

The landscape of political imprisonment in Northern Ireland was changed due to the general release and reintegration of politically motivated prisoners as part of the Belfast Agreement. This article reflects upon the post-prison experiences of former prisoners and their families, and in particular how the move from a resistant to a transitional framework has facilitated a greater openness and willingness amongs ex-prisoners to acknowledge the personal and familial problems related to incarceration. We also explore the ways in which ex-prisoners have attempted to deal with the continued social, political and civic exclusion which arises as a result of their conflict-related 'criminal' convictions. In the final section of the article, the authors further develop the move from a resistant to a transitional characterization of incarceration and its consequences.

'Sometimes I wish I was an "ex" ex-prisoner': identity processes in the collective action participation of former prisoners in Northern Ireland

Since the signing of the Northern Ireland peace agreement a plethora of community based prisoner self-help organisations have been established wherein former prisoners staff, manage and deliver services to colleagues. By forging and maintaining their collective identities through community based mutual aid, members of these self-help organisations have progressed to create not only individual change/assistance but have also developed and evolved to tackle serious wider social issues which impact on the members of their organisations. This article critically analyses how the conditions of a post conflict society can influence both the development and evolution of these organisations and also how members situate their claims about the self in the organisation and beyond. Using the social movement framework it is argued that the work of these self-help organisations have given rise to a new politics of identity … that is the ‘politically motivated’ ex-prisoner. ©2013 Taylor & Francis

α-Tocopherol induces proatherogenic changes to HDL2 & HDL3: An in vitro and ex vivo investigation

Introduction: High density lipoproteins (HDL) have considerable potential for improving cardiovascular health. Additionally, epidemiological studies have identified an inverse relationship between a-tocopherol intake and cardiovascular disease, which has not been translated in randomised controlled trials. Objectives: This study assessed if increased α-tocopherol within HDL2 and HDL3 (HDL2&3) influenced their antiatherogenic potential. In the first of two in vitro investigations, the oxidation potential of HDL2&3 was assessed when α-tocopherol was added following their isolation. In the second, their oxidation potential was assessed when HDL2&3 were isolated from serum pre-incubated with α-tocopherol. Additionally, a 6-week placebo-controlled intervention with α-tocopherol assessed if α-tocopherol influenced the oxidation potential and activities of HDL2&3-associated enzymes, paraoxonase-1 (PON-1) and lecithin cholesteryl acyltransferase (LCAT). Results: Conflicting results arose from the in vitro investigations, whereby increasing concentrations of α-tocopherol protected HDL2&3 against oxidation in the post-incubated HDL2&3, and promoted HDL2&3-oxidation when they were isolated from serum pre-incubated with α-tocopherol. Following the 6-week placebo-controlled investigation, α-tocopherol increased in HDL2&3, while HDL2&3 became more susceptible to oxidation, additionally the activities of HDL2&3-PON-1 and HDL2-LCAT decreased. Conclusion: These results have shown for the first time that α-tocopherol induces changes to HDL2&3, which could contribute to the pathophysiology of cardiovascular disease.

Mundane Mobilities in ‘Post-Socialist’ Sofia: Making Urban Borders Visible

This article reflects on an on-going research project which aims to expand the understanding of the production and transformation of urban borders in the Eastern European cities of the ex ‘communist bloc’, starting from the case of Sofia. It explores the proposition that there has been a prolific process of wall making in this city associated with ‘vanishing public spaces’, ‘rescaling of enclosure’, and ‘corrosion of the collective urban realm’ (Hirt, 2012). The paper seeks to understand the social and political effects of this process by delving into the sensorial, emotional and embodied experiences associated with the mundane mobilities of urban residents. Using participants’ self-directed photography and videos from ‘walk-along’ interviews it explores the ways in which borders are made visible and are produced, challenged or resisted through mobility, and delves into the associated senses of deepening social and spatial differentiation in the city.
