Behavioral phenotype of the reeler mutant mouse: effects of RELN gene dosage and social isolation.

Abstract: Reeler (rl/rl) and reeler/wild-type (+/rl) mice synthesize Reln at subnormal rates, as do patients with schizophrenia, bipolar disorder, and autism, thereby forming the basis for a Reln hypothesis for vulnerability to these psychopathologies and justifying attention to the behavioral phenotypes of Reln-deficient mice. Tests of gait, emotionality, social aggression, spatial working memory, novel-object detection, fear conditioning, and sensorimotor reflex modulation revealed the behavioral phenotype of rl/rl, but not +/rl, mice to be different from that of wild-type (+/+) mice. These results reveal no effect of Reln gene dosage and provide significant challenges to both the Reln and the neurodevelopmental hypotheses of the etiology of major psychopathologies.

Assessment of regression kriging for spatial interpolation – comparisons of seven GIS interpolation methods

Abstract: As an important GIS function, spatial interpolation is one of the most often used geographic techniques for spatial query, spatial data visualization, and spatial decision-making processes in GIS and environmental science. However, less attention has been paid on the comparisons of available spatial interpolation methods, although a number of GIS models including inverse distance weighting, spline, radial basis functions, and the typical geostatistical models (i.e. ordinary kriging, universal kriging, and cokriging) are already incorporated in GIS software packages. In this research, the conceptual and methodological aspects of regression kriging and GIS built-in interpolation models and their interpolation performance are compared and evaluated. Regression kriging is the combination of multivariate regression and kriging. It takes into consideration the spatial autocorrelation of the variable of interest, the correlation between the variable of interest and auxiliary variables (e.g., remotely sensed imag...

Aquatic Insect Ecology

Abstract: Publisher Summary Aquatic insects are abundant in most freshwater habitats and often exhibit high diversity. In aquatic food webs, they serve as food items for nearly the full range of vertebrate and invertebrate predators, and many function as predators themselves. This chapter provides a brief overview of: constraints on aquatic insect species diversity, life history, and community structure; the role of aquatic insects in ecosystem processes; the impact of land use, climate change, and disturbances on their communities; and the utility of aquatic insects in biomonitoring studies. The review encompasses both lentic and lotic habitats, as well as a brief coverage of saline habitats. The discussion is placed in the context of how physical and life history factors constrain the distribution and abundance of aquatic insects, thereby altering communities and ecosystem function.

Parents and Peers in Relation to Early Adolescent Problem Behavior

Abstract: Concurrent and prospective associations between parent-youth dyadic hostility and adolescent externalizing and internalizing problem behavior were examined in a sample of 416 families. Parenting control parents well-being and youths affiliation with deviant peers were included as integral covariates. Information from multiple sources was analyzed using structural equation modeling. Concurrently youth externalizing problems were associated with dyadic hostility deviant peers inadequate parenting control and fathers well-being (inversely). Internalizing problems were associated with inadequate parenting control and lower levels of fathers well-being. Prospectively some of these relations continued over 2 years with a few new associations emerging. A process model is proposed in which parent-youth dyadic hostility during early adolescence influences parenting peer relations and parents well-being over time. (authors)

The development of a goal to become a teacher.

Abstract: The purpose of this project was to investigate how the goal of becoming a teacher emerges. The study used interviews to develop goal histories for 8 preservice teachers. There tended to be 4 sources of influence for their goal to become a teacher: (a) family influences, (b) teacher influences, (c) peer influences, and (d) teaching experiences. The categories developed from the interviews to describe the types of influences those sources provided were (a) suggesting that the person become a teacher, (b) encouraging the person to become a teacher, (c) modeling teaching behavior, (d) exposing the person to teaching experiences, and (e) discouraging the person from becoming a teacher. In addition, influences such as critical incidents, emotions, and social-historical factors, such as the status and pay of teachers, were prominent in the goal histories of the participants. Finally, the results of the study are discussed within the context of goals and self-directed behavior.
