A Blueprint for Democratic Policing Anywhere in the World? Police Reform, Political Transition and Conflict Resolution in Northern Ireland

This article provides an overview of the police reform process undertaken in Northern Ireland since 1999 as part of a broader program of conflict resolution. It considers the recommendations of the Independent Commission on Policing (ICP), which proposed a number of changes to policing structures and arrangements in Northern Ireland, and it assesses the degree to which these have been operationalized in the 8 years since the ICP published its report. It suggests that although the police reform process in Northern Ireland has been moderately successful and provides a number of international best practice lessons, the overall pace of change has been hindered by difficulties of implementation and, more fundamentally, by developments in the political sphere and civil society.

Indicadores de sostenibilidad ambiental en el periurbano de la ciudad de Mar del Plata, Argentina

Los indicadores de sostenibilidad conforman herramientas útiles para la toma de decisiones. Las ciudades latinoamericanas, y especialmente las áreas de expansión sin planificación adecuada, enfrentan desafíos cada vez mayores para revertir problemáticas que amenazan su sostenibilidad. El presente trabajo evalúa de manera preliminar, la sostenibilidad ambiental del periurbano de Mar del Plata (Argentina) tomando como referencia algunos de los indicadores propuestos por el modelo del Banco Interamericano de Desarrollo en la Iniciativa Ciudades Emergentes y Sostenibles. Se construyó un índice sintético (Índice de Sostenibilidad Ambiental, ISA) que integra trece indicadores agrupados en ocho temas. Las situaciones más críticas (ISA: 0,45-0,558) se identifican fundamentalmente en zonas en las que se desarrollan actividades rurales y en las que se localizan asentamientos de carácter precario. El estudio realizado profundiza en el conocimiento de la dimensión ambiental de la sostenibilidad, enfatizando en el análisis de los contrastes internos del periurbano marplatense.

Foxp3+ T cells induce Perforin-Dependent Dendritic Cell Death in Tumor-Draining Lymph Nodes.

Regulatory T (Treg) cells limit the onset of effective antitumor immunity, through yet-ill-defined mechanisms. We showed the rejection of established ovalbumin (OVA)-expressing MCA101 tumors required both the adoptive transfer of OVA-specific CD8(+) T cell receptor transgenic T cells (OTI) and the neutralization of Foxp3(+) T cells. In tumor-draining lymph nodes, Foxp3(+) T cell neutralization induced a marked arrest in the migration of OTI T cells, increased numbers of dendritic cells (DCs), and enhanced OTI T cell priming. Using an in vitro cytotoxic assay and two-photon live microscopy after adoptive transfer of DCs, we demonstrated that Foxp3(+) T cells induced the death of DCs in tumor-draining lymph nodes, but not in the absence of tumor. DC death correlated with Foxp3(+) T cell-DC contacts, and it was tumor-antigen and perforin dependent. We conclude that Foxp3(+) T cell-dependent DC death in tumor-draining lymph nodes limits the onset of CD8(+) T cell responses.

Fasciola hepatica: Histological changes in the reproductive structures of triclabendazole (TCBZ)-sensitive and TCBZ-resistant flukes after treatment in vivo with TCBZ and the related benzimidazole derivative, Compound Alpha

Twenty-four shed-reared lambs were each infected orally with 250 metacercariae of Fasciola hepatica, using either the triclabendazole (TCBZ)-sensitive Cullompton isolate or the TCBZ-resistant Sligo isolate. Twelve weeks after infection the lambs were treated with TCBZ (10 mg/kg) or with the experimental fasciolicide, Compound Alpha (Cpd alpha), a benzimidazole derivative of TCBZ (15 mg/kg). The lambs were euthanised 48,72 and 96 h after TCBZ treatment, or 24, 48 and 72 h after Cpd a treatment, and flukes were collected from the liver and/or gall bladder of each animal. Untreated animals harbouring 12-week infections were euthanised 24 h after administration of anthelmintic to the treatment groups, and the untreated flukes provided control material. A semi-quantitative assessment of the degree of histological change induced by the two drugs after different times of exposure was achieved by scoring the intensity of three well-defined lesions that developed in the testes and uteri of a representative sample of flukes from each lamb. In general, it was found that in those tissues where active meiosis and/or mitosis occurred (testis, ovary, and vitelline follicles), there was progressive loss of cell content due to apparent failure of cell division to keep pace with expulsion of the mature or effete products. Further, actively dividing cell types tended to become individualised, rounded and condensed, characteristic of apoptotic cell death. Protein synthetic activity was apparently inhibited in the Mehlis' secretory cells. In the uterus, where successful formation of shelled eggs represents the culmination of a complex sequence of cytokinetic, cytological and synthetic activity involving the vitelline follicles, the ovary and the Mehlis' gland, histological evidence indicating failure of ovigenesis was evident from 24 h post-treatment onwards. The development of these lesions may be related to the known antitubulin activity of the benzimidazole class of anthelmintics, to the induction of apoptosis in cells where mitosis or meiosis has aborted due to failure of spindle formation, and to drug-induced inhibition of protein synthesis. The semi-quantitative findings indicated that Cpd a is slightly less efficacious than TCBZ itself in causing histological damage to the reproductive structures of TCBZ-sensitive flukes, and that, like TCBZ, it caused no histological damage in flukes of the TCBZ-resistant isolate. This study illustrates the potential utility of histological techniques for conveniently screening representative samples of flukes in field trials designed to validate instances of drug resistance or to test the efficacy of new products against known drug-resistant and drug-susceptible fluke isolates. It also provides reference criteria for drug-induced histopathological changes in fluke reproductive structures which may aid interpretation of TEM findings. (C) 2009 Elsevier B.V.

Demanding Recognition: Equality, Respect, and Esteem

This article argues that we must distinguish between two distinct currents in the politics of recognition, one centred on demands for equal respect which is consistent with liberal egalitarianism, and one which centres on demands for esteem made on behalf of particular groups which is at odds with egalitarian aims. A variety of claims associated with the politics of recognition are assessed and it is argued that these are readily accommodated within contemporary liberal egalitarian theory. It is argued that, pace Taylor, much of what passes for `identity' or recognition politics is driven by demands for equal respect, not by demands for esteem/affirmation. Given the inherently hierarchical nature of esteem recognition, no liberal state can consistently grant such recognition. Furthermore, these demands pose the risk of intensifying intergroup competition and chauvinism. Esteem recognition is valuable for individuals, but plays a problematic role for egalitarian politics.

The Supremacy of the Sequence: Key Elements and Dimensions in the Process of Change

How single organizations manage the process of change and why only some of them are able to actually reach radical change are central questions in today’s theoretical debate. The role played by the process of change and its dimensions (namely, pace, sequence and linearity), however, has been poorly investigated. Drawing on archetype theory, this paper explores: (i) whether a specific pace of radical change exists; (ii) whether different outcomes of change are characterized by different sequences of change in key-structures and systems (iii) how the three dimensions of the process of change possibly interact. As an example of organizational change the study takes into consideration processes of accounting change in three departments of two Canadian and two Italian municipalities. The results suggest the supremacy of the sequence of implemented changes over the other two dimensions of the process in order to achieve a radical outcome of change.

Evolution of Organisational Structure and Capabilities in Internationalising Banks: The CEE Operations of UniCredit's Vienna Office

Cross-border integration is the central management issue for banks that expand internationally, and this is especially true in Central and Eastern Europe, where the pace of internationalisation through mergers and acquisitions has been rapid. A critical challenge in cross-border integration is aligning a multinational company's formal organizational structure with the distribution of capabilities across its subsidiary units, and this issue is explored by tracking the co-evolution of organizational structure and capabilities during the internationalisation of a large banking network into this region. Our focus is the Vienna head office of Bank Austria Creditanstalt, which was acquired first by HypoVereinsbank (Germany) and then UniCredit (Italy). Despite its formal role being downgraded during these changes, the unit continued to develop its distinctive capabilities. The key insight our article offers is that managing cross-border integration is not simply about recognizing the value of the distinctive capabilities of individual units and designing formal structures that successfully align with them. It is also about understanding the need for dynamic interaction between formal corporate structure and individual units' desires to retain power and influence, which have significant implications for the development of their organizational capabilities.
