Spatial genetic structuring in a vagile species, the European wood mouse

We examined the genetic structure of natural populations of the European wood mouse Apodemus sylvaticus at the microgeographic ( 30 km) scales. Ecological and behavioural studies indicate that this species exhibits considerable dispersal relative to its home-range size. Thus, there is potential for high gene flow over larger geographic areas. As levels of population genetic structure are related to gene flow, we hypothesized that population genetic structuring at the microgeographic level should be negligible, increasing only with geographic distance. To test this, four sites were sampled within a microgeographic scale with two additional samples at the macrogeographic level. Individuals (n=415) were screened and analysed for seven polymorphic microsatellite loci. Contrary to our hypothesis, significant levels of population structuring were detected at both scales. Comparing genetic differentiation with geographic distance suggests increasing genetic isolation with distance. However, this distance effect was non-significant being confounded by surprisingly high levels of differentiation among microgeographic samples. We attribute this pattern of genetic differentiation to the effect of habitat fragmentation, splitting large populations into components with small effective population sizes resulting in enhanced genetic drift. Our results indicate that it is incorrect to assume genetic homogeneity among populations even where there is no evidence of physical barriers and dispersal can occur freely. In the case of A. sylvaticus, it is not clear whether dispersal does not occur across habitat barriers or behavioural dispersal occurs without consequent gene flow.

The University Incubator: Insights in the Entrepreneurial Process from a Network Perspective

Research to date has identified incubator units as an effective mechanism for supporting the growth and development of small entrepreneurial firms. Advantages are gained not only from the provision of appropriate facilities and external managerial expertise on site, but also from the opportunity to develop entrepreneurial networks facilitated by the spatial proximity of incubator firms. Therefore, the research question upon which the paper is based investigates the impact of context, in other words the degree to which the networking opportunities provided by the university incubator support the small firm in its pursuit of sustainability and growth

3,5-dimethyl-4-amino-1,2,4-triazole (Dat) as a tridentate ligand in the polymeric cations of [Ag-3(Dat)(2)](NO3)(3)

Colourless single crystals of [Ag-3(Dat)(2)](NO3)(3) were obtained from a reaction of silver(l) nitrate and 3,5-dimethyl-4-amino-1,2,4-triazole (Dat). In the crystal structure (orthorhombic, Fdd2, Z = 8, a = 1100.1(2), b = 3500.3(2), c = 1015.4(3) pm, R, = 0.0434) there are two crystallographically non-equivalent silver sites in a one (Ag1) to two ratio (Ag2). Both resemble linear N-Ag-N coordination although angles are 163 degrees and 144 degrees, respectively Each Dat ligand coordinates with the two ring nitrogen atoms at 216 to 219 pm and with one amino-nitrogen atom at 229 pro. According to the composition [Ag-3(Dat)(2)](3+) = [(Dat)Ag-3/2](3+), a polymeric structure is built with all Ag+ ions bridging.

Listening – the Cinderella profile component of English

This article investigates the role of listening in English. The importance of ‘reading with the ear’ is discussed, as is research into the views of teachers and pupils on this topic. Practical suggestions are made for according to listening a more meaningful place in English. Originally English was conceived as listening and reading, talking and writing. It would enrich the conception of English as a subject to uncouple listening from talking and instead give it its place as a profile component in its own right.

‘Stakeholders’ views of legal and advice services for people admitted to psychiatric hospital’

This paper describes a study that used a mixed method approach to elicit the views of a range of stakeholders about experiences of compulsory admission to psychiatric hospital, and the use of the Mental Health Review Tribunal (MHRT). The paper begins with an introduction to the background of the study, one that took place in Northern Ireland, a region in the UK with its own mental health legislation and policy. A review of literature is then presented. This highlights some of the disadvantages that service users and carers face when dealing with professionals during and following compulsory admission to hospital. This section concludes with an overview of literature on the MHRT in the UK. A range of methods was used to gather data from the following stakeholders: five service user and carer focus group interviews (n = 44); interviews with four lawyers experienced in Tribunal work; an interview with a legal member of the Tribunal; a survey of solicitors who identified themselves as equipped to carry out Tribunal work; interviews with three managers of organisations that provided patient advocacy services; letters to hospital managers requesting information provided to patients and carers. The findings reveal a number of themes associated with these experiences of compulsory admission to hospital and subsequent use of the Tribunal. Service users and carers generally found it difficult to access relevant information about rights, information provided by hospital managers was uneven and lawyers were often not familiar with processes associated with compulsory admission. There was a range of views about the Tribunal. Most respondents felt that the Tribunal was necessary and mostly satisfactory in the way it carried out its functions, but stakeholders raised a number of issues. Carers in particular felt that they should be more involved in decision-making processes, whereas lawyers tended to be focused on more technical, legal issues. Problems of regrading prior to the Tribunal and in examining medical evidence were highlighted by lawyers. There was an appeal for better information and advice by service users and carers, and recognition of the need for better training and education for lawyers. The paper concludes with a brief discussion about current mental health law in the UK, arguing that, in this context, professionals should more proactively use information and advice that can enable service users and carers to defend their rights.
