Influence of urbanization on the occurrence and activity of aerial insectivorous bats

Activity and species-specific responses of insectivorous bats in different urban-forest conditions provides a general perspective on the adaptability and vulnerability of bat species towards urbanization intensity. Here we evaluated species richness and activity patterns of aerial insectivorous bats across an urbanized landscape in the highlands of Chiapas, in Mexico. Acoustic monitoring of echolocation calls was conducted for 27 nights over a period of four months. Species richness and relative activity of insectivorous bats were estimated in a landscape with different conditions of urbanization intensity: urban areas, non-urban and forest areas. We identified a total of 14 bat species and three phonotypes. Bat species richness and relative activity was similar (X² = 0.568, gl = 2, p > 0.05), but species composition differed among conditions. We observed a significant higher occurrence of Bauerus dubiaquercus, Eptesicus brasiliensis and Myotis californicus in forest sites. Urban sites presented higher occurrence of Molossus rufus and phonotype Molossidae 2, while non-urban sites presented a higher occurrence of Eptesicus furinalis and phonotype Molossidae 2. We were able to identify bat species according to their relative activity in relation todifferent landscape conditions. Species of the Molossidae family presented the highest activity in urban sites, which was positively affected by the number of streetlights, while species of the Vespertilionidae presented the highest activity in forest sites, which was positively related totree density. While urbanization tends to diminish native biodiversity and alter faunal communities, our results show a similar richness and relative activity of aerial insectivorous bats along the urban ecosystem. The effect of urbanization intensity becomes more apparent in species-specific bat activity; the response of species towards particular habitat conditions depends on local habitat quality and characteristics (i.e., presence of streetlights, vegetation cover and tree density).     

Foreign Direct Investment in the Caribbean

This article addresses the question of whether the Caribbean is particularly attractive or unattractive to foreign investors, and if it has specific characteristics that attract or deter FDI. An econometric analysis of data from 135 countries for 1980‐2002 shows that the Caribbean does not suffer from low inflows of FDI; on the contrary, Caribbean countries receive more FDI than comparable countries in other regions. This reflects two contradictory effects. On the one hand, FDI inflows may be particularly sensitive to political instability in the region; on the other hand, the absence of regulation appears to have been a particularly beneficial factor in attracting FDI to the Caribbean.     

Norway: relevance of the social development model for post-War welfare policy

This article examines the extent to which social policies in post-War Norway fit three key features of the social development model, namely productivism, social investment and universalism. The historical review shows that the pursuit of a social development model changes in line with economic development and the expansion of the welfare state. It reveals that policies to promote full employment have been central to the country's economic and welfare policies throughout the post-War period. Nevertheless, the extent to which the productivist objective has been emphasised and implemented has fluctuated over time. In contrast to the 1970s and 1980s, the 1990s witnessed a strengthening of the work ethic but also a continued commitment to de-commodification. The extent to which the combination of productivism and social investment is pursued is examined with reference to services for the insured and uninsured. The article concludes that the ways in which the social development perspective understands and defends universalism and social investment only partially applies to the mature Norwegian welfare state.     

Associations Online: Barriers for Using Web-Based Communication in Voluntary Associations

Despite the high adoption level of Facebook and other social network sites (SNSs) in Norway, local level voluntary associations have not embraced SNSs to the same degree. Regular websites are the main web representation, and information provision is the main function of the associations’ web representations. Using quantitative data on website content and organizational characteristics we have analyzed which factors hinder SNS adoption. The results point to size and complexity of associations and to age-based digital divides among members as important factors for having a profile on a SNS. It seems that a certain numerical point must be reached in terms of organizational and community size, for SNSs to be useful. Also, older members, smaller economy and a low degree of formalization in associations might hamper the implementation of SNSs in associations. Using Norway as a critical case, this article contributes new knowledge about web communication in voluntary organizations, an increasingly important field of research internationally.     

How Do Individuals Apply Risk Information When Choosing Among Health Care Interventions?

A sample of 3,201 Danes was subjected to personal interviews in which they were asked to state their preferences for risk-reducing health care interventions based on information on absolute risk reduction (ARR) and relative risk reduction (RRR). The aim of the study was to measure the relative weighting of different types of risk information under various circumstances. The effect of presenting questions, and of explicitly formulating RRR, was analyzed. A preference for increases in RRR was demonstrated. There was a stronger inclination to choose the intervention that offered the highest RRR if RRR was explicitly stated. Individuals with more than 10 years of schooling also demonstrated a preference for increased ARR, but only when facing individually framed choices. In a social choice context, preferences for RRR remained intact, but the magnitude of ARR had no impact on choices. Results imply that social framing may induce a propensity to prefer interventions that target high-risk populations. Those respondents who had received < or = 10 years of schooling demonstrated preferences for RRR but not ARR, and no impact of social framing was observed.     

Pluriactivity in rural Norway

This article relates the results of a study carried out on the roles and functions of pluriactivity in rural Norway. The study sought to define the effect on pluriactivity of the integration of rural areas into urban labour markets, international systems of production, and the changes in the sectoral mix in rural areas. The analysis is based on three types of data: a list of enterprises from the national register of economic units, the central register of employed workers, and information from local informants in the sample municipalities. The article concludes that the rate of pluriactivity among the rural population depends on the way in which economic sectors are classified. A further finding is that pluriactivity is an important feature of rural Norway, but is still mainly associated with agricultural enterprise. A final conclusion is that pluriactivity has other characteristics in larger labour markets than in smaller labour markets in rural areas due to the urban influence on the former.     

Theorizing indicators

Policymakers and social theorists have increasingly come to rely on social indicators to guide their decisions and theories. Social indicators are also useful in bridging theory and empirical research as well as the traditional gap between policymaking and social theory. The concept of social indicators covers interpretation of cultural signs, simple statistical measures, and complex statistical indexes related to sets of domains. The article views the development of child well-being indicators as central not only in the social welfare field, but as an indicator of future societal conditions, given that children’s lives are especially sensitive to social change. The paper addresses the development of indicators of children’s well-being, arguing that the expansion of the field, the complexity of new domains and indicators, and the position of children as “being” and “becoming”, they are citizens of the present as well as being socialized for the future, illustrates that the next crucial step for the field is to further elaborate theories and models.     

„Aber es gibt keine Antisemiten mehr“: Eine experimentelle Studie zur Kommunikationslatenz antisemitischer Einstellungen

Since the public sanctioning of anti-Semitism after 1945 has mostly prevented the articulation of anti-Semitic attitudes in public they outlast in private. This development was taken into account by the theory of anti-Semitism, in particular by the concept of communication latency, but had almost no impact on the data collection process. For the sensitive character of anti-Semitic attitudes it is uncertain whether they are reported truthfully in surveys. Respondents are assumed to answer in a socially desirable manner. Using an experimental setting, we demonstrate that the cognitive activation of an anti-Semitic primary group norm increases the prevalence of self-reported anti-Semitism. In addition, we show that under statistical control of this communication mechanism the explanatory power of established determinants of anti-Semitic attitudes such as education, political attitudes, and political interest decreases.     

What Determines the Substantive Influence of Public Participation? An Investigation of Planners’ Views on Conditions for Participatory Practices in Denmark

Conditions that enable successful public participation have received increased attention in research and practice. This paper contributes with an empirical study of the conditions that determine the substantive influence of public participation processes. We explore a list of conditions in a Danish context through a survey of practitioners’ perceptions of practice and through interviews with practitioners. The findings support the growing criticism of the widespread notion that the choice of methods is a fundamental determinant of the success of public participation. The findings lead us to propose a more prominent role of contextual conditions in practice.
