Behavioral responses of rural and urban greater white-toothed shrews (Crocidura russula) to sound disturbance

Urban Ecosystems - The development of urban areas imposes challenges that wildlife must adapt to in order to persist in these new habitats. One of the greatest changes brought by urbanization has...     

Career Concerns,Values, and Role Salience in Employed Men

This study tested Super's model of career adaptability by examining the relationships between career development concerns, values, and role salience among 881 men employed full-time in a cement factory. They responded to the Adult Career Concerns Inventory, the Values Inventory, and the Salience Inventory. The inter-correlations of the resulting scores were appropriately small and coincided with theoretical predictions. A principal components analysis clarified the latent structure of the relations between and among the scales. The results supported both Super's model of career adaptation and his model for Career Development Assessment and Counseling.     

Cross‐Cultural Perspectives on Career Assessment

The authors present an overview of the discussion and presentations that took place concerning techniques and assessment in educational and vocational guidance at the recent symposium International Perspectives on Career Development. Two topics were examined. The 1st focused on the theoretical foundations of and psychometric issues in career assessment. The 2nd focused on the practice of career assessment and the use of career measures, particularly in cultural contexts for which the measures were not originally developed.     

Disentangling the Governance Configurations of Strategic Spatial Plan-Making in European Urban Regions

This paper is aimed at assessing and disentangling how territorial governance configurations influence contemporary practices in strategic plan-making in 14 European urban regions. The findings allow us to distinguish three dominant practices: i) plan-making shaped by consensus building and multilevel government cooperation; ii) plan-making shaped by the involvement of profit-oriented actors and negotiations, and iii) plan-making shaped by consolidated planning practice. To truly grasp plan-making practice, it is necessary to scrutinize who rules and who is ruled while negotiations are unfolding, as well as the extent to which private actors’ interests influence how spatial development goals and strategies are defined.     

‘Here and There’: Children and Youth’s Perspectives of Borders in Mexico–United States Migration

This article explores children’s perspectives regarding migration and family separation on both sides of the Mexico‐U.S. border. ‘Transnational care constellations’¹ that connect separated siblings allow children to imagine the other side of the border and to explore their thoughts and perspectives through the lenses of inequality, as well as through a sense of belonging and family. This article presents ethnographic data of families that capture the dynamism of families that are both ‘here and there’ as children assemble their ideas and narratives of how transnational lives exist.     

An Ecological Model for Quantitative Risk Assessment for Schistosomiasis: The Case of a Patchy Environment in the Coastal Tropical Area of Northeastern Brazil

We developed a stochastic model for quantitative risk assessment for the Schistosoma mansoni (SM) parasite, which causes an endemic disease of public concern. The model provides answers in a useful format for public health decisions, uses data and expert opinion, and can be applied to any landscape where the snail Biomphalaria glabrata is the main intermediate host (South and Central America, the Caribbean, and Africa). It incorporates several realistic and case‐specific features: stage‐structured parasite populations, periodic praziquantel (PZQ) drug treatment for humans, density dependence, extreme events (prolonged rainfall), site‐specific sanitation quality, environmental stochasticity, monthly rainfall variation, uncertainty in parameters, and spatial dynamics. We parameterize the model through a real‐world application in the district of Porto de Galinhas (PG), one of the main touristic destinations in Brazil, where previous studies identified four parasite populations within the metapopulation. The results provide a good approximation of the dynamics of the system and are in agreement with our field observations, i.e., the lack of basic infrastructure (sanitation level and health programs) makes PG a suitable habitat for the persistence and growth of a parasite metapopulation. We quantify the risk of SM metapopulation explosion and quasi‐extinction and the time to metapopulation explosion and quasi‐extinction. We evaluate the sensitivity of the results under varying scenarios of future periodic PZQ treatment (based on the Brazilian Ministry of Health's plan) and sanitation quality. We conclude that the plan might be useful to slow SM metapopulation growth but not to control it. Additional investments in better sanitation are necessary.     

Asymptotic theory for maximum likelihood estimates in reduced-rank multivariate generalized linear models

Reduced-rank regression is a dimensionality reduction method with many applications. The asymptotic theory for reduced rank estimators of parameter matrices in multivariate linear models has been studied extensively. In contrast, few theoretical results are available for reduced-rank multivariate generalized linear models. We develop M-estimation theory for concave criterion functions that are maximized over parameter spaces that are neither convex nor closed. These results are used to derive the consistency and asymptotic distribution of maximum likelihood estimators in reduced-rank multivariate generalized linear models, when the response and predictor vectors have a joint distribution. We illustrate our results in a real data classification problem with binary covariates.
