Social competence in Zimbabwean multicultural schools: Effects of ethnic and gender differences

S tudents' social competence was investigated in relation to race/ethnicity and gender for a sample of 371 Zimbabwean students attending racially/ethnically integrated schools. About 42% of the students were black, and 58% white (mean age 12 years; SD=9 months). Peer and teacher sociometric ratings of children's social behaviour, social responsibility, and friendliness comprised the social competence measures. Tests of empirical independence among these social competence measures supported their uniqueness in reliably assessing components of the general construct of social competence among Zimbabwean students. Multiple analysis of variance procedures were used to examine the relationship between social competence statuses and group membership (i.e., race/ethnicity, gender) while controlling for aggregate scores and classroom racial proportions. Superior academic achievement and racial/ehnic propinquity are social status levelling factors in multiracial school settings. Teachers rated white students higher on social responsibility and social behaviour. Students rated white students higher on social responsibility only. Comparisons of social competence by ethnicity and gender revealed that white and female students were rated significantly higher on social behaviour and social responsibility than their black and male classmates. Female students were perceived as more socially competent or better adjusted to school than males. Reliable differences in social competence in race/ethnicity and gender groups were concentrated in peer ratings of social responsibility and in teacher ratings of social behaviour and social responsibility. In postcolonial settings or settings with a history of race/ethnicity and gender‐based privilege, minorities from a dominant culture may have higher social status than peers from a majority culture. Superior social competence in females is a resource for school adaptation and social climate. Students have perceptions of social competence in peers that only partially overlap with those of teachers and contribute uniquely to their experience of school. Social competence in students is multifaceted, gendered, and differently perceived by teachers and peers.     

Latent inhibition and context change in psychometrically defined schizotypy

The disruption of latent inhibition within the schizophrenia spectrum has often been interpreted either as a result of increased attentional distractibility (attentional account) or as a result of deficient interference of past associations (associative account). The aim of the present investigation was to test competing predictions, as derived from the above theoretical accounts. In a visual search paradigm of latent inhibition, accuracy was examined as a function of prior experience with the target, and psychometrically defined schizotypy. In Experiment 1 (N=60), no context change was introduced. In accord with past evidence, latent inhibition was found to be intact in low-, but disrupted in high-schizotypy scorers, a result predicted both by attentional and associative accounts. In Experiment 2 (N=60), a context change was introduced. As predicted by past evidence, latent inhibition was disrupted in low-schizotypy scorers. However, latent inhibition was found to be intact in high-schizotypy scorers, a finding accommodated by attentional, but not associative accounts. Theoretical implications and alternative interpretations are also considered.     

Heuristic Value of Eclecticism in Theory Development: The Case of Piagetian-Vygotskian <Emphasis Type="Italic">dialogue</Emphasis> about Proportional Reasoning

Køppe’s proposition of four layers in theoretical building are used here in the exploration of a specific case of eclectic combination, the use of Piagetian and Vygotskian general approaches to the analysis of proportional reasoning as a cognitive mathematical ability. It is proposed here that the eclectic consideration of these contributions depends on the consideration of their specificity, in the sense that they highlight different aspects of the phenomenon under scrutiny, and also on the consideration of the coherence between this eclectic convergence and premises in terms of schools of thought under which each contribution is framed. We conclude proposing in accordance to S. Køppe’s proposal that eclecticism can be valuable and heuristic in theory development, but this contribution will depend largely on the effort in establishing careful relations between the four layers of theory-building.     

Temporomandibular Disorder in Brazilian Patients: A Preliminary Study

The objective of the current study was to evaluate disease-related beliefs, adherence to treatment, quality of life, coping strategies and cognitive status in a group of Brazilian patients with Temporomandibular Disorder (TMD). Thirty patients were evaluated with a semi-directed interview, the Coping Strategies Inventory, and a Mini-Mental State Examination. Although half (50%) of the patients had known their diagnosis long term, 40% of the sample were not correctly following proposed treatment. All patients had a similar pattern of pain behavior related to TMD, while disease-related beliefs, quality of life and coping strategies were variable. Expectations about treatment also had significant association with treatment adherence. The findings of this study suggest that a more thorough understanding of individual differences in TMD is warranted.     

Systemic administration of a nitric oxide synthase inhibitor impairs fear sensitization in the plus-maze

The aim of the present study was to evaluate the occurrence of fear sensitization in rats previously treated with an inhibitor of the NO syntheses and submitted to Trial1/Trial2 plus-maze (PM) procedure. Male Wistar rats received a systemic treatment with N(omega)-nitro-L-Arginine-methyl ester (L-NAME; 5, 10 or 50 mg kg(-1)) and were submitted to PM Trial1. In the following day the animals were re-exposed to the PM with no drug administration (Trial2). Some standards spatial-temporal measures, such as the percentage of entries (% Open arm entries) and time spent (% Open arm time) in the open arms and risk assessment frequency were recorded and used to estimate the animal level of fear sensitization in PM Trial2. The results showed that animals receiving L-NAME (50 mg kg(-1)) displayed increased % Open arm entries and % Open arm time in Trial2 in relation to the group receiving 0.9% saline, which is compatible with impaired fear/anxiety acquisition during Trial1/Trial2 PM procedure. In addition, rats treated with L-NAME (50 mg kg(-1)) exhibited low level of risk assessment in Trial2 in relation to the group treated with 0.9% saline, which indicates low level of fear/anxiety during PM re-exposure. The number of entries into the enclosed arms was not changed by any L-NAME treatment, which suggests no bias of the drug treatments on animal locomotor activity. The data suggest that NO synthesis may mediate the fear sensitization process in the PM.     

CONCURRENT RESURGENCE AND BEHAVIORAL HISTORY

The contribution of past experiences to concurrent resurgence was investigated in three experiments. In Experiment 1, resurgence was related to the length of reinforcement history as well as the reinforcement schedule that previously maintained responding. Specifically, more resurgence occurred when key pecks had been reinforced on a variable-interval 1-min schedule than a variable-interval 6-min schedule, but this effect may have been due either to the differential reinforcement rates or differential response rates under the two schedules. When reinforcement rates were similar (Experiment 2), there was more resurgence of high-rate than low-rate responding. When response rates were similar (Experiment 3), resurgence was not related systematically to prior reinforcement rates. Taken together, these three experimental tests of concurrent resurgence illustrate that prior response rates are better predictors of resurgence than are prior reinforcement rates.     

The Quality of Home Environment in Brazil: An Ecological Model

Based on Bronfenbrenner's (1999) ecological perspective, a longitudinal, prospective model of individual differences in the quality of home environment (Home Observation for Measurement of the Environment—HOME) was tested in a sample of 179 Brazilian children and their families. Perinatal measures of family socioeconomic status (SES) and child birth weight had direct effects on HOME at preschool age. As either family SES or child birth weight increased, HOME also increased through diminished emotional distress in the mother a month following childbirth. SES had a negative effect on number of children in the household, which in turn had a long-term negative impact on HOME. Compared to mothers who had reported not to plan their pregnancy, those who did were more likely to have fewer children, to report more spouse support during childbearing, and to show less emotional distress a month after childbirth, all of which also influenced HOME at preschool age. These findings are discussed in light of the broader socio-ecological Brazilian context, with direct implications to clinical practice aimed at improving the quality of home environment.     

From a Distance: Pastoral Care and Theological Education

Abstract. This article is a presentation and discussion of a seminary course on the Corinthian Correspondence. The pedagogical model for this course was structured to parallel the pattern of Paul's pastoral care from a distance as he relates to the Corinthian congregation by personal visits, delegations from and to the congregation, letters from and to the congregation, and unofficial grapevine types of communication. The course was designed for dispersed students to interact with the Corinthian letters, with each other, and with myself as instructor in ways that 1) simulate a first‐century exchange between congregation and apostle and 2) facilitate careful interpretive work on the message of these letters, including their contemporary relevance.     

Using Past Performance, Proxy Efficacy, and Academic Self-Efficacy to Predict College Performance

This study examined the ability of prior academic performance, proxy efficacy, and academic self-efficacy to predict college academic performance. Participants ( N  = 202) completed a modified version of the Teacher Collective Efficacy scale ( Goddard, 2001 ), the Academic Self-Efficacy scale ( Elias & Loomis, 2000 ), and a demographic questionnaire. Prior performance was predictive of both academic self-efficacy beliefs and college performance. Hierarchical regression analysis indicates that academic self-efficacy beliefs explain a significant amount of unique variance beyond past performance in predicting college performance. Proxy efficacy did serve as a predictor of student academic self-efficacy, but did not serve as a predictor of college performance. Implications for instructors, as well as for future research, are discussed.
