Selected AbstractsUrbanization and the more-individuals hypothesisJOURNAL OF ANIMAL ECOLOGY, Issue 2 2010Claudia Chiari Summary 1.,Urbanization is a landscape process affecting biodiversity world-wide. Despite many urban,rural studies of bird assemblages, it is still unclear whether more species-rich communities have more individuals, regardless of the level of urbanization. The more-individuals hypothesis assumes that species-rich communities have larger populations, thus reducing the chance of local extinctions. 2.,Using newly collated avian distribution data for 1 km2 grid cells across Florence, Italy, we show a significantly positive relationship between species richness and assemblage abundance for the whole urban area. This richness,abundance relationship persists for the 1 km2 grid cells with less than 50% of urbanized territory, as well as for the remaining grid cells, with no significant difference in the slope of the relationship. These results support the more-individuals hypothesis as an explanation of patterns in species richness, also in human modified and fragmented habitats. 3.,However, the intercept of the species richness,abundance relationship is significantly lower for highly urbanized grid cells. Our study confirms that urban communities have lower species richness but counters the common notion that assemblages in densely urbanized ecosystems have more individuals. In Florence, highly inhabited areas show fewer species and lower assemblage abundance. 4.,Urbanized ecosystems are an ongoing large-scale natural experiment which can be used to test ecological theories empirically. [source] Varieties of Industrial Relations Research: Take-over, Convergence or Divergence?BRITISH JOURNAL OF INDUSTRIAL RELATIONS, Issue 2 2005Carola M. Frege Industrial relations (IR) research faces various pressures of internationalization. Not only do global economic forces increasingly shape the subject of the discipline, employment relations, but also the academic community itself is becoming more international. The article discusses whether and in what ways IR research is affected by these trends. It is based on a comparative, longitudinal study of journal publications in the USA, Britain and Germany. The findings reveal significantly different patterns of IR research across the three countries. In particular, the strong variation between US and British research patterns challenges the common notion of a homogeneous Anglo-Saxon style in conducting social science research. The analysis suggests that despite growing internationalization, IR research continues to be strongly embedded in nationally specific research cultures and traditions. [source] STRATEGIC RESEARCH AND DEVELOPMENT POLICY: SOCIETAL OBJECTIVES AND THE CORPORATE WELFARE ARGUMENTCONTEMPORARY ECONOMIC POLICY, Issue 1 2009RICHARD T. GRETZ The article considers the optimal research and development subsidy regime in a two-firm two-country model where each firm is "located" in a specific country. Trade is intra-industry in that customers in both countries purchase from both firms. The article suggests that when both countries subsidize their local firm usually welfare increases compared to the case of zero subsidies. Making the same comparison, profit always falls in the symmetric game and falls about half the time in the asymmetric game. These results call into question some common notions about corporate welfare.

Guldberg Abstract This paper analyses a sample of online discussions to evaluate the development of adult learners as reflective practitioners within a networked learning community. The context for our study is a blended learning course offering post-experience professional training to non-traditional university students. These students are parents and carers of people with autistic spectrum disorder (ASD). We use Lave and Wenger's ,communities of practice' as a theoretical framework for establishing how students develop a learning community based upon mutual engagement, joint enterprise and shared repertoires. Those three aspects are analysed according to two measures. The first focuses on learner appropriation of the professional discourse, values and goals of the ASD carer through the network. The second relates to changes in the quality of collaborative activity over time. Our analysis demonstrates that students belong to an overarching community of practice, with different subsets who work at sharing and co-constructing common understandings. This shared discourse and common notions of what constitutes good practice help create a safe interaction space for the students. Once group identity is consolidated, more challenging questions emerge and the group are able to define further common values, understandings and goals through processes of resolution. [source] Mindsets, rationality and emotion in Multi-criteria Decision AnalysisJOURNAL OF MULTI CRITERIA DECISION ANALYSIS, Issue 4 2005Fred WenstøpArticle first published online: 21 SEP 200 Abstract This paper discusses the paradigm of multi-criteria decision analysis (MCDA), and relates it to other disciplines. It concludes that MCDA needs a larger, not smaller, emphasis on values and subjectivity to increase rationality in decision-making. The paper bases the argument on a conciliation of ethics, philosophy, neuro-psychology and management paradigms. It observes that the MCDA ,mindset' relates to consequentialism, as opposed to virtue ethics and rule based ethics. Virtues and rules play an important role in practical decision-making, however. Findings in neuro-psychology show that reliable decision-making requires emotions. Elicitation of emotions is therefore required in MCDA value trade-off processes. This leads to a concept of emotional rationality, which defines rationality as a four-dimensional concept that includes well-founded values and breaks radically with common notions of rationality. Virtues do not easily lend themselves to value trade-off, but questions of virtue usually creates strong social emotions, as opposed to the feebler global emotions that may arise in connection conventional trade-off of end values. The conclusion is that MCDA should not be shy of subjectivity and emotion, but instead put more emphasis on it to increase rationality. A part of this challenge is how to deal with questions of virtue in decision-making. Copyright © 2006 John Wiley & Sons, Ltd. [source] "Concrete" Computer Manipulatives in Mathematics EducationCHILD DEVELOPMENT PERSPECTIVES, Issue 3 2009Julie Sarama Abstract, The use of "concrete manipulatives" in mathematics education is supported by research and often accepted as a sine qua non of "reform" approaches. This article reviews the research on the use of manipulatives and critiques common notions regarding concrete manipulatives. It presents a reformulation of the definition of concrete as used in educational psychology and educational research and provides a rationale of how, based on that reformulation, computer manipulatives may be pedagogically efficacious. The article presents 7 hypothesized, interrelated affordances of manipulatives and briefly reviews evidence for their empirical validity. [source] | ||||||||||
