Selection of sites for successful restoration of impacted shellfish populations depends on understanding the dispersion capability and habitat requirements of the species involved. In Strangford Lough, Northern Ireland, the horse mussel (Modiolus modiolus) biogenic reefs cover only a fraction of their historical range with the remaining reefs badly damaged and requiring restoration. Previous experimental trials suggest that translocation of horse mussels accelerates reef recovery and has therefore been proposed as a suitable restoration technique. We used a series of coupled hydrodynamic and particle dispersal models to assess larval dispersion from remnant and translocated populations to identify suitable areas for adult live M. modiolus translocation in Strangford Lough, Northern Ireland. A maximum entropy model (MAXENT) was used to identify if dispersing larvae could reach habitat suitable for adult M. modiolus. From these we predicted if translocated mussels will reseed themselves or be able to act as larval sources for nearby reefs. The dispersal models showed that the remnant M. modiolus populations are largely self-recruiting with little connectivity between them. The majority of larvae settled near the sources and movement was largely dependent on the tides and not influenced by wind or waves. Higher reef elevation resulted in larvae being able to disperse further away from the release point. However, larval numbers away from the source population are likely to be too low for successful recruitment. There was also little connectivity between the Irish Sea and Strangford Lough as any larvae entering the Lough remained predominantly in the Strangford Narrows. The areas covered by these self-seeding populations are suitable for M. modiolus translocation according to the MAXENT model. As a result of this work and in conjunction with other field work we propose a combination of total protection of all remaining larval sources and small scale translocations onto suitable substrata in each of the identified self-recruiting areas.

Background: Research on barriers to professional advancement for women in academic medicine has not adequately considered the role of environmental factors and how the structure of organizations affects professional advancement and work experiences. This article examines the impact of the hierarchy, including both the organization's hierarchical structure and professionals' perceptions of this structure, in medical school organization on faculty members' experience and advancement in academic medicine. Methods: As part of an inductive qualitative study of faculty in five disparate U.S. medical schools, we interviewed 96 medical faculty at different career stages and in diverse specialties, using in-depth semistructured interviews, about their perceptions about and experiences in academic medicine. Data were coded and analysis was conducted in the grounded theory tradition. Results: Our respondents saw the hierarchy of chairs, based on the indeterminate tenure of department chairs, as a central characteristic of the structure of academic medicine. Many faculty saw this hierarchy as affecting inclusion, reducing transparency in decision making, and impeding advancement. Indeterminate chair terms lessen turnover and may create a bottleneck for advancement. Both men and women faculty perceived this hierarchy, but women saw it as more consequential. Conclusions: The hierarchical structure of academic medicine has a significant impact on faculty work experiences, including advancement, especially for women. We suggest that medical schools consider alternative models of leadership and managerial styles, including fixed terms for chairs with a greater emphasis on inclusion. This is a structural reform that could increase opportunities for advancement especially for women in academic medicine. © 2010 Copyright Mary Ann Liebert, Inc.

Recent decades have seen significant advances in research on the relationship between nationalist ideology and organized violence. New scholarship has paid much closer attention to the microdynamics of violence, the strikingly uneven distribution of violence, the relationship between master cleavages and intimate local and personal struggles, and to process, history, and contingency. Nationalist ideology is understood to be bound up intimately with institutions and with everyday relationships at the local level. We introduce the contributions to this special issue, outlining the way in which they highlight the power of ideas, narratives, and microlevel solidarity in mobilization for violence and how they address the crucial importance of territoriality in linking ideas and action.

As a society, we have a responsibility to provide an inclusive built environment. As part of the need to promote inclusion, there is now a growing trend to place pupils with Special Educational Needs (SEN) into a mainstream school setting. This is often facilitated by providing a specialist SEN resource base located within the mainstream school. If so, the following paper outlines why the whole school should be considered when locating and implementing a SEN resource base. It also highlights the wider opportunities for enhancing inclusion for SEN pupils if giving holistic thought to the wider context of the resource base. It then indicates a four-stage approach, using the ASD pupil as an illustrative example, to help evaluate the optimum SEN resource base location within a mainstream school setting. Finally it highlights in conclusion, some benefits and challenges for an enriched school environment for all pupils, if considering genuine inclusion.
