Predicting the Risk of Biological Invasions Using Environmental Similarity and Transport Network Connectedness

Understanding the risk of biological invasions associated with particular transport pathways and source regions is critical for implementing effective biosecurity management. This may require both a model for physical connectedness between regions, and a measure of environmental similarity, so as to quantify the potential for a species to be transported from a given region and to survive at a destination region. We present an analysis of integrated biosecurity risk into Australia, based on flights and shipping data from each global geopolitical region, and an adaptation of the “range bagging” method to determine environmental matching between regions. Here, we describe global patterns of environmental matching and highlight those regions with many physical connections. We classify patterns of global invasion risk (high to low) into Australian states and territories. We validate our analysis by comparison with global presence data for 844 phytophagous insect pest species, and produce a list of high‐risk species not previously known to be present in Australia. We determined that, of the insect pest species used for validation, the species most likely to be present in Australia were those also present in geopolitical regions with high transport connectivity to Australia, and those regions that were geographically close, and had similar environments.     

Symbolic Interaction as Music: The Esthetic Constitution of Meaning,Self, and Society

Analytical frameworks such as dramaturgy and narrative analysis are respectively grounded in metaphors of life as theater and life as a story. In related fashion, in this article the authors argue for the creation of another metaphor: life as music. Viewing selfhood and symbolic interaction as music sensitizes us to observe and understand an important but much too neglected dimension of social life: the esthetic. Drawing from the pragmatist philosophy of John Dewey, the authors argue that the realm of the esthetic should not be confined to museums and art galleries, for the intentional perception of beauty constitutes the very foundation of individuals' embodied experiences of their lifeworlds. From within our metaphor of life as music we conceptualize beauty as the diverse rhythms, melodies, and harmonies contributing to the constitution of both subjectivity and intersubjectivity.     

Leslie matrix models

A review of the Leslie matrix model theory and its literature 1941-1987 is presented. The point of view is that of a mathematician who focuses on the parts of the theory which are relevant to demography. Works of a decidedly applied nature are not dealt with.     

Intra-industry diversification effects under firm-specific contingencies on the demand side

How do firm-specific, demand-related factors influence the relationship between intra-industry diversification (IID) and performance? Recent findings regarding the performance effects of IID depict a complex picture with curvilinear relationships and several contingencies. However, firm-specific contingencies on the demand side have remained unexplored. We analyze how IID relates to firm performance (market share) in the German automotive industry using panel data between 1999 and 2008. We specifically focus on a firm's high-quality brand image as a demand-side contingency. We find support for our hypotheses of complex curvilinear relationships as well as for moderating effects of brand quality. Our results have significant theoretical implications for the IID literature.     

Schooling a European Identity: ethno‐cultural exclusion and nationalist resonance within the EU policy of “The European dimension of education”

This article aims to explore how the role of education as an aide in the process of “European” identity formation is being articulated in the European Union's (EU) policy of “The European dimension of education”. After having located the EU's views on education in the context of the neo‐liberal discourse on economic globalization, the article goes on to trace EU discussions of the European dimension of education historically. Subsequently, it deliberates on the understanding of European culture and identity which the European dimension of education endeavours to advance. Here a critique is developed of the policy's ethno‐culturalism, thereby excluding delineation of a collective identity in the EU. Basing itself on a notion of cultural identity which, implicitly, includes only those who fit certain versions of European historical “roots” and cultural “heritage”, the policy, it is argued, impedes a discussion of how a trans‐ethnic identity formation could be created in today's EU. Towards the end of the article, a scrutiny of the European dimension's perception of the so‐called “language diversity” in the EU seeks to illustrate this issue further.     

‘There is always this feeling of otherness’: exploring the lived experiences of visually impaired immigrant women in Canada

This paper explores the experiences of immigrant women with visual impairment in the Greater Toronto and Hamilton Area (GTHA) of Canada. Conceptually, the paper draws from feminist disability theory and critical scholarship on blindness to consider the discursive and material processes shaping women’s experiences across different socio-cultural contexts. Empirically, the paper draws from in-depth interviews with seven women. The analysis is organized around three themes. The first explores women’s understandings of visual impairment. The second examines the ways in which women’s experiences of visual impairment are shaped by meanings and attitudes that circulate within their cultural communities, and the extent to which immigration might challenge or reinforce these meanings. The third examines the shifting barriers and opportunities women face with respect to social and economic participation. We close by identifying the conceptual implications of our research.     

‘What you need to do is …’: social work students’ reflections on an advice giving audit exercise

This paper reports on qualitative research investigating the advice giving behaviours of social work students. Second-year students, who were enrolled in an interpersonal communication skills course, were required to undertake an ‘advice-giving audit’ exercise across 6 days, with the aim of strengthening their awareness of the interactive nature of advice giving. Students then wrote a diary entry about the frequency of their everyday advice giving behaviour, its intent and reception. Nineteen students provided these reflections for analysis. Findings included three themes pertaining to advice-giving: (i) Giving advice as a natural, comfortable and unconscious way of communicating; (ii) Power and position influences advice dissemination, and (iii) Withholding advice opens, deepens and confuses norms of communication. A fourth theme pertained to the insights that students reported from engaging with the exercise. These findings illustrate the complex interactional process associated with professional advice giving. The research also suggests that experiential activities, which are conducted outside of the classroom, have significant potential to promote the critical examination of embedded communicative practices.
