Personal and family factors as predictors of pupils' mathematics achievement

This study examined personal and family factors in prediction of mathematics achievement by Kuwaiti fourth graders (395 boys, 501 girls; M age=10.0 yr., SD=8.0 mo.). Personal variables included sex, total achievement, perception of parental involvement, pupil's attitude towards school, and mathematics achievement. Family variables included parental education and parental involvement, views of school, and income. The data had good fit with the suggested model. Analysis showed variables which had significant direct association with mathematics achievement were total achievement and sex. Parental education, pupil's sex, and attitude towards school had significant indirect associations with mathematical achievement. Associations were direct for boys and indirect for girls on mathematics achievement, so sex had minimal total effects on mathematics achievement.     

Community Influences on Adjustment in First Grade: An Examination of an Integrated Process Model

We examined the impact of neighborhood characteristics both directly and indirectly as mediated by parent coaching and the parent/child affective relationship on behavioral and school adjustment in a sample of urban dwelling first graders. We used structural equations modeling to assess model fit and estimate direct, indirect, and total effects of neighborhood structural and social characteristics on parenting behavior and child outcomes. Observed physical incivilities in the neighborhood were associated with lower levels of parent eliciting behavior and higher levels of child behavior problems. The effects of neighborhood structural characteristics were mediated partially through neighborhood community involvement with children, which had a direct significant impact on parent eliciting behavior and an indirect effect on child behavior problems. Neighborhood community involvement with children was associated with higher levels of parent eliciting behavior and lower levels of child behavior problems. Observed physical incivilities had a significant indirect association with poor school adjustment and a marginally significant association with positive school adjustment to first grade. Neighborhood community involvement with children was more strongly associated with positive school adjustment than poor school adjustment.     

Eye-blink conditioning is associated with changes in synaptic ultrastructure in the rabbit interpositus nuclei

Eye-blink conditioning involves the pairing of a conditioned stimulus (usually a tone) to an unconditioned stimulus (air puff), and it is well established that an intact cerebellum and interpositus nucleus, in particular, are required for this form of classical conditioning. Changes in synaptic number or structure have long been proposed as a mechanism that may underlie learning and memory, but localizing these changes has been difficult. Thus, the current experiment took advantage of the large amount of research conducted on the neural circuitry that supports eye-blink conditioning by examining synaptic changes in the rabbit interpositus nucleus. Synaptic quantifications included total number of synapses per neuron, numbers of excitatory versus inhibitory synapses, synaptic curvature, synaptic perforations, and the maximum length of the synapses. No overall changes in synaptic number, shape, or perforations were observed. There was, however, a significant increase in the length of excitatory synapses in the conditioned animals. This increase in synaptic length was particularly evident in the concave-shaped synapses. These results, together with previous findings, begin to describe a sequence of synaptic change in the interpositus nuclei following eye-blink conditioning that would appear to begin with structural change and end with an increase in synaptic number.     

Cognitive Coping Tool Kit for Psychosis: Development of a Group-Based Curriculum

This article outlines an 8-week curriculum that was created to help outpatients develop cognitive and behavioral skills for coping with delusions and hallucinations as well as to reduce patients’ comorbid subjective levels of distress (e.g., depression, anxiety). The manualized protocol consisted of psychoeducation and training in a variety of CBT skills that have shown promise in treating individuals with residual psychosis, using recovery-oriented “naturalistic” methods and culminating in the creation of an individualized “tool kit” of cognitive coping resources. A preliminary study of the effectiveness of this brief group-based CBT program for outpatients with chronic, residual symptoms of schizophrenia was conducted. Participants were 24 outpatients diagnosed with schizophrenia spectrum disorders who were stable on medications and connected to case management community follow-up. The Positive and Negative Syndrome Scale for Schizophrenia interview and the Symptom Checklist-90 self-report symptom scales were administered pre- and post-intervention. The results suggest that there were significant improvements in psychotic symptoms and self-reported distress from pre- to posttreatment.     

Metaperceptions of bias in intimate relationships

Meta-awareness of bias in intimate partner judgments was investigated in 3 studies. In Study 1, participants rated fictional partners in happier relationships as more positively biased in their partner perceptions. In Study 2, participants thought their judgments of their own current partners were positively biased and that they were judged by their partners in a positively biased fashion. Using a sample of couples, Study 3 showed that metaperceptions of bias were anchored to actual levels of bias at the individual and relationship levels. In addition, positive bias was accentuated for traits that were more relevant to mate evaluation. These findings (as expected) suggest that positive bias in partner judgments can be a normative and consciously accessible feature of intimate relationships.     

Posture control and complex arm coordination: analysis of multijoint coordinative movements and stability of stance

The authors addressed the interactions between control of bimanual multijoint coordination tasks and posture. Participants (N = 6) performed 8 coordination patterns that differed in degree of complexity by using their bilateral elbows and wrists under 3 scaled motion speeds while standing on 2 force plates. Results indicated that producing complex bimanual multijoint coordinative tasks affected postural sway, thus resulting in an increase of sway activity. Behavioral as well as mechanical factors accounted for the increased disturbance in postural sway. Those findings suggest that performing complex coordination tasks disrupts postural control in normal young adults.     

Predictors of online information seeking by international students when disaster strikes their countries.

This study explores factors influencing international students' likelihood of using the Internet to seek disaster-related information should a disaster affect their countries. A cross-sectional survey was conducted in two universities in America between August 1 and September 30, 2005. Two hundred twenty-nine (n = 229) students completed the self-administered questionnaires. ANOVA analyses found that respondents' Internet self-efficacy had no significant impact on their intentions to seek disaster-related information on the Internet. However, respondents' Internet dependency and attitude toward seeking information online were found to have a significant effect on such intentions.     

真理、符合与收缩论

The central claim of this essay is that many deflationary theories of truth are variants of the correspondence theory of truth. Essential to the correspondence theory of truth is the proposal that objective features of the world are the truthmakers of statements. Many advocates of deflationary theories (including F. P. Ramsay, P. F. Strawson and Paul Horwich) remain committed to this proposal. Although T-sentences (statements of the form “s is true iff p”) are presented by advocates of deflationary theories of truth as truisms or analytic truths, T-sentences are often understood as entailing commitment to the central proposal of the correspondence theory.
