Internetworking and the Politics of Science: NSFNET in Internet History

This article presents an account of the process of development of the NSFNET and its significance for the emergence of the Internet of the 1990s. The fact that the development of the interconnected system of computer networks occurred within the realm of academic research is not incidental. The dynamics of the world of scientific research were intimately related to the shaping of the network and to the way in which it spread to other sectors of society. The construction of computer networks crossed the boundaries between science and society in order to build the scientific realm by transforming the world in which it is embedded.     

The Developmental Sequence and Relations Between Gesture and Spoken Language in Toddlers With Autism Spectrum Disorder

In typical development, gestures precede and predict language development. This study examines the developmental sequence of expressive communication and relations between specific gestural and language milestones in toddlers with autism spectrum disorder (ASD), who demonstrate marked difficulty with gesture production and language. Communication skills across five stages (gestures, word approximations, first words, gesture-word combinations, and two-word combinations) were assessed monthly by blind raters for toddlers with ASD participating in an randomized control trial of parent-mediated treatment (N = 42, 12–30 months). Findings revealed that toddlers acquired skills following a reliable (vs. idiosyncratic) sequence and the majority of toddlers combined gestures with words before combining words in speech, but in contrast to the pattern observed in typical development, a significant subset acquired pointing after first words.     

Development of the Multicultural School Psychology Counseling Competency Scale

The purpose of this study was to begin to delineate competencies needed by school psychologists in the provision of counseling services to culturally diverse clients and to develop an exploratory measure of multicultural counseling competence in school psychology practice. The present article discusses the development and preliminary psychometric characteristics of the Multicultural School Psychology Counseling Competency Scale (MSPCCS). The MSPCCS, which assesses trainers' perceptions of the multicultural school psychology counseling competencies of graduating trainees, was administered to a national sample of directors of school psychology training programs. Preliminary findings, based on a 57% return rate, suggest that the scale has good internal consistency reliability. Results of the factor analysis support a one factor solution for the scale. Specific considerations in the use of the scale are discussed, and suggestions for future research are presented. © 1997 John Wiley & Sons, Inc.     

Peer relationships in adolescent competitive soccer: Associations to perceived motivational climate,achievement goals and perfectionism

The aim of this study was to examine the relationship between the perceived motivational climate, achievement goals, perfectionism and indices of peer relationships in a sample of young male and female Norwegian soccer players. The sample consisted of 1719 experienced soccer players (1231 males, 488 females) aged 12?–?19 years (mean = 14.9 years) participating in the Norway Cup international youth soccer competition. The players responded to a questionnaire measuring perceived peer acceptance and quality of friendship in soccer, perceived motivational climate, achievement goals and perfectionism in soccer. Canonical correlation analyses revealed that young female players who perceived the motivational climate as predominantly mastery oriented, and who were moderately task oriented and scored negatively on maladaptive perfectionism, reported better relations with their peers in soccer. Constructive peer relations were evident in that they scored positively on companionship with their best friend in soccer; they perceived this friend as being loyal and of allowing free discussion, and they reported being socially accepted by their peers in soccer. Mirroring these findings, young male players who perceived the motivational climate as predominantly performance oriented, who had a moderately negative score on task orientation but a quite strong positive score on maladaptive perfectionism, reported negative relationships with peers in terms of these aspects. They also reported being in conflict with their best soccer friend. The findings suggest that the qualities of motivation have a systematic relationship with peer acceptance and the quality of friendship in male and female youth soccer.     

Causal Attributions following Success and Failure at an Achievement Motor Task

Abstract

Past research has shown that success is predominantly attributed to internal factors and failure attributed to external factors. The purpose of the present experiment was to determine whether this attributional pattern was also found when subjects were performing a motor task. The degree of ego involvement in the task (evaluation) and the effect of prior practice (novelty) were also investigated in order to determine the extent to which these variables affect subjects' self-attributions. Thus, the effects of ego involvement and past experience following success and failure on causal attributions were investigated in a 2 × 2 × 2 (evaluation × novelty × outcome) factorial design with 80 college undergraduates. The task was a motor maze. Consistent with past research, subjects showed a relative tendency toward internal attributions over external attributions and a tendency toward stable attributions over unstable attributions. Moreover, success increased the relative bias toward internal attributions. However, evaluation apprehension and experience with the motor task did not interact with outcome to affect internal and external attributions.     

Is reported childhood sexual abuse associated with the psychopathological characteristics of patients who experience auditory hallucinations?

OBJECTIVE: The aim of this study was to determine whether reported childhood sexual abuse is related to the severity of symptoms in patients who experience auditory hallucinations. METHOD: A sample of 26 adult male and females with psychotic disorders involving auditory hallucinations were interviewed and were asked to complete three self-report measures: the Dissociative Experiences Scale (DES-II and DES-taxon versions); the Beck Depression Inventory (BDI); and the Beliefs About Voices Questionnaire (BAVQ). They were also asked about any history of sexual abuse in childhood. RESULTS: A history of childhood sexual abuse was reported by 10 of the 26 patients (38.5%), and was associated with higher levels of depression and dissociation, as well as being linked to a tendency to regard the voices as more malevolent. The same three features were all associated with the age at first reported abuse, with a younger age of first experience being related to higher levels of psychopathology in all instances. CONCLUSIONS: These results require replication and refinement in future research, but indicate a need for greater attention to be paid to the possible role of childhood sexual abuse when understanding and treating auditory hallucinations.     

Detecting Differential Item Functioning Using Logistic Regression Procedures

A logistic regression model for characterizing differential item functioning (DIF) between two groups is presented. A distinction is drawn between uniform and nonuniform DIF in terms of the parameters of the model. A statistic for testing the hypothesis of no DIF is developed. Through simulation studies, it is shown that the logistic regression procedure is more powerful than the Mantel-Haenszel procedure for detecting nonuniform DIF and as powerful in detecting uniform DIF.     

Emotion regulation and academic perceptions in adolescence

Although studied extensively in the field of adolescent mental health, the role of emotion regulation (ER) in the academic functioning of adolescents is not well understood. This study examined the role of ER in adolescents’ perceptions of themselves and their learning environments. We compared adolescents with high and low levels of ER on perceptions of school achievement and attitudes towards school and their perception of their parents’ academic involvement. Students completed surveys about perceptions of their learning and parental involvement, as well as their ER abilities. Results indicated that students with higher emotion dysregulation endorsed more negative self-perceptions of their own academic abilities, had more negative attitudes towards school, and rated their mothers and fathers as more controlling in relation to their learning. These results demonstrate the importance of ER in the academic context, particularly in the home learning environment.
