Social skills interventions across school settings: Case study reviews of students with mild disabilities

This study investigates the efficacy of a social skills training program with seven mildly handicapped students across three school settings: regular classroom, special education resource room, and recess. It was found that social skills training generated improvement on both pre-post measures and behavior ratings. Improvements were maintained 2 weeks after treatment was discontinued for seven students. All students' performance generalized from resource room to regular classroom settings; only four students' performance generalized to the recess setting.     

Acute effects of different warm-up protocols on highly skilled golfers’ drive performance

Previous research has highlighted the positive effect that different warm-up protocols have on golf performance (e.g. Sorbie et al., 2016; Tilley & Macfarlane, 2012) with the design of warm-ups and programmes targeting and improving golf performance through the activation and development of specific muscle groups. This study aimed to examine the acute effects of two warm-up protocols on golf drive performance in comparison to a control condition. Using a randomised counterbalanced design over three testing sessions, twenty-three highly skilled golfers completed the control, dynamic and resistance-band warm-up conditions. Following each condition, a GC2 launch monitor was used to record ball velocity and other launch parameters of ten shots hit with the participants’ own driver. A repeated-measures ANOVA found significant increases in ball velocity (η_p² = .217) between the control and both the dynamic and resistance-band warm-up conditions but no difference between these latter two, and a reduction in launch angle between control and dynamic conditions. The use of either a dynamic stretching or resistance-band warm-up can have acute benefits on ball velocity but golfers should liaise with a PGA Professional golf coach to effectively integrate this into their golf driving performance.     

Concurrent validity of the Woodcock-Johnson tests of cognitive ability with the WISC-R: EMR children

The Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) were administered in a counterbalanced order to 30 children referred for a three-year reevaluation. All children were currently placed in an educable mentally retarded (EMR) program. The children ranged in age from 8-0 to 12-5 years, with a mean of 10-6. The correlation coefficient between the WISC-R and WJTCA was observed to be .72. Significant mean differences were found between the WISC-R and WJTCA full scale standard scores. The implications of the findings are discussed relative to the placement of children in classes for the mentally retarded. Explanations for the mean differences between the WJTCA and WISC-R also are explored.     

Teacher pupil control ideology and pupils' projected feelings toward teachers

The relationship between teacher pupil control ideology and pupils' projected feelings toward teachers was examined. The Pupil Control Ideology Form, based on a custodial-humanistic continuum, served as the operational definition for teacher views toward pupil control. Lemeshnik's Draw-A-Teacher technique, a projective device based on a negative-positive continuum, served as the operational definition of pupils' projected feelings toward teachers. A sample of 131 teachers and their students responded to these instruments, respectively. Pearson product-moment correlations indicated that custodialism in teacher pupil control ideology was directly related to pupils' negative feelings toward teachers. Multiple regression analysis indicated that pupil control ideology, followed by teacher sex and grade level, predicted pupils' feelings toward teachers. Further analysis revealed that boys projected more negative feelings toward teachers than did girls.     

A guide to McCarthy interpretation

The aim of the present study was to develop a system of tables to facilitate interpretation of the McCarthy Scales of Children's Abilities. Tables are presented that organize the McCarthy subtests according to Bannatyne's, Sattler's, and Meeker's systems of interpretation. In addition, tables that organize the McCarthy Scales into categories that reflect factors likely to influence various subtests are presented. These tables will provide a more structured approach to McCarthy interpretation and a straightforward empirical method for generating hypotheses regarding individual strengths and weaknesses in intellectual ability.     

Does the WISC-R measure verbal intelligence for nonenglish-speaking children?

Zarske, Moore, and Petersen's (1981) article that examined the factor structure of the WISC-R for “diagnosed learning disabled” children was critiqued. These authors concluded that the WISC-R “is an appropriate measure of general intellectual abilities” (p.407), but the present author suggests that this conclusion does not follow from their factor analytic data. The makeup of the sample also is questioned, and implications of their findings for the practitioner are discussed.     

CERN: Past performance and future prospects: II. The scientific performance of the CERN accelerators

In a series of three papers, we attempt to evaluate the past scientific performance of the three main particle accelerators at the Geneva-based European Organization for Nuclear Research (CERN) over the period since 1960, and to assess the future prospects for CERN and its users during the next ten to fifteen years.We concerned ourselves in a previous paper (Paper 1 - Martin and Irvine [51] with the position of the CERN accelerators in world high-energy physics relative to those at other large laboratories working in the field. We dealt primarily with the period from 1969 to 1978, and attempted to establish how the experimental output from the three principal CERN accelerators, taken as a whole, compared with that from other major facilities. In undertaking this comparative evaluation, we drew on the method of “converging partial indicators” used in previous studies of three Big Science specialties.In contrast, this paper (Paper II) focuses in detail on the scientific performance of each of the CERN accelerators taken individually. In particular, it asks, first, how the outputs from the CERN 28 GeV (giga or billion electron-volts) Proton Synchrotron compare with those from a very similar 33 GeV American accelerator at Brookhaven National Laboratory over the past two decades? Second, how great have been the experimental achievements of the Intersecting Storage Rings in world terms? And, third, how do the outputs from the CERN 400 GeV Super Proton Synchrotron and from a rival American machine at Fermi National Accelerator Laboratory compare? Attempts are then made to identify the main factors responsible for determining the relative scientific performance of each CERN machine.These factors are of relevance to the subject of a third paper (Paper III - Martin and Irvine [52]) which sets out to assess the future prospects for CERN and in particular for LEP, the large electron-positron collider scheduled for completion in the latter part of the 1980s. What are the construction requirements (financial and technical) associated with LEP, and how easily will they be met? How does the scientific potential of LEP compare with that of other major accelerators under construction around the world? And, in the light of the previous record of the CERN accelerators, to what extent is this potential likely to be realized? The paper concludes with a discussion of the extent to which predictive techniques can be utilized in the formulation of scientific priorities, and of the problems in current science policy-making that such techniques might help address.     

The influence of self-determination in physical education on leisure-time physical activity behavior

Using a multitheory approach, this study was designed to investigate the influence of urban adolescents' perceived autonomy and competence in physical education on their physical activity intentions and behaviors during leisure time. A transcontextual model was hypothesized and tested. Urban adolescents (N=653, ages 11-15 years) completed questionnaires assessing relevant psychological constructs and moderate to vigorous physical activity and then had their cardiorespiratory fitness assessed with the Progressive Aerobic Cardiovascular Endurance Run (PACER) test. Based on our structural equation modeling analyses and fit indexes, the transcontextual model adequately fit the data. We concluded that the two theoretical frameworks--SDT and theory of planned behavior--can be integrated to provide an enhanced understanding of the influence of physical education on leisure-time physical activity. The results revealed that perceived autonomy and competence in physical education are interrelated and function as a whole for enhancing leisure-time physically active intentions and behavior.
