A negative ion source test facility.

Progress is being made in the development of an Ion Source Test Facility (ISTF) by D-Pace Inc. in collaboration with Buckley Systems Ltd. in Auckland, NZ. The first phase of the ISTF is to be commissioned in October 2015 with the second phase being commissioned in March 2016. The facility will primarily be used for the development and the commercialization of ion sources. It will also be used to characterize and further develop various D-Pace Inc. beam diagnostic devices.

Necrotizing and eosinophilic masticatory myositis in farmed mink: a preliminary description.

This report describes necrotizing and eosinophilic myositis affecting the masticatory muscles of a group of mink. Affected animals demonstrated sudden death with marked subcutaneous oedema over the dorsal head. The temporalis and masseter muscles were pale, swollen and friable. Histologic changes consisted of varying degrees of myodegeneration, myonecrosis and inflammation. Eosinophils were prominent in the inflammatory infiltrate. Similar to dogs, masticatory muscles in mink were found to contain unique type 2M fibres, suggesting a possible target for an immune response. Aerobic and anaerobic tissue cultures of the affected musculature revealed no significant pathogens. Histological and nutritional analyses were not typical of vitamin E/selenium deficiency. This case series supports the existence of a novel disease entity in mink with some features comparable with masticatory muscle myositis in dogs.

Intervention-based assessment: rates of evaluation and eligibility for specific learning disability classification.

Intervention-based assessment, a systematic form of prereferral intervention, represents a viable alternative to "test and place" models for identifying and teaching children with a variety of learning-related problems in schools. Data obtained from 13 schools participating for a third year in a pilot study of statewide implementation of intervention-based assessment suggested that, in comparison to a prior prereferral intervention model, fewer children are evaluated and found eligible for special education. Of those children receiving intervention-based assessment, a slight decrease occurs in the percentage classified as specifically learning disabled.

Breaking the cycle of violence: an examination of factors relevant to treatment follow-through.

To examine differences between a group of battered mothers who followed through with treatment recommended for their children and those who did not, 10 women from each of two comparable women's shelters who followed through with recommended therapy for their children were compared with 10 women from each shelter who did not follow through, in regard to age, years of education, job history, economic status, and prior exposure to therapy. Analysis indicated that women who followed through had significantly more years of education than those women who did not follow-through. Furthermore, women who followed-through were significantly more likely to have had prior experience in counseling or therapy as were their mates. Implications, including education of mothers about the emotional needs of their children by peers, staff, or liaison workers from mental health agencies as a positive means of curtailing transmission of violent patterns from parents to children, are discussed.

Utility of the Stanford-Binet IV Abbreviated Form for placing exceptional children.

Stanford-Binet IV General Purpose Abbreviated Battery Scores were extracted from full battery administrations given to 19 developmentally handicapped children in a naturally occurring sample. The Pearson correlation with complete test Composite Scores was .94 (p less than .001). Short-form scores were higher in 47%, lower in 21%, and the same in 32% of the cases.

The Stanford-Binet, Fourth Edition: a small study of concurrent validity.

To date most studies of construct and concurrent validity of the Stanford-Binet Intelligence Scale, Fourth Edition, have employed an established measure of ability as the criterion. Here achievement, assessed by the Wide Range Achievement Test-Revised and the Peabody Individual Achievement Test, was the criterion for establishing concurrent validity. The sample consisted of a naturally occurring group of 21 children referred for learning difficulties. The results provided partial support for the theoretical model of the Stanford-Binet IV. Intercorrelations among individual Stanford-Binet IV and achievement subtest scores were examined to generate explanatory hypotheses for those predictions which were not empirically supported. Finally, correlations between the WISC-R and the achievement measures were compared with those between the Stanford-Binet IV and the achievement measures. Examination shows that the correlations of the Stanford-Binet IV with achievement are as strong as and sometimes stronger than those between the WISC-R and achievement.

Comparing scores on the Stanford-Binet, Fourth Edition with the WISC-R for exceptional children.

The purpose of the present study was to examine the performance of a sample of 19 exceptional children on both the Stanford-Binet Intelligence Scale, Fourth Edition (Stanford-Binet IV) and the WISC-R. Construct validity studies of the Stanford-Binet IV with the WISC-R have yielded results which provide only partial support for predictions derived from the theoretical model underlying this new measure. The results obtained for the naturally occurring sample of exceptional children indicate nonsignificant differences in performance between Stanford-Binet IV and WISC-R Full Scale IQ. As with prior studies, results provide only partial support for the predictions derived from the theoretical model. Explanatory hypotheses for the observed discrepancies are discussed.

Social orientation and the social self-esteem of gifted and talented female adolescents.

Carlson's developmental theory of self-concept provides a theoretical explanation for equivalent levels of self-esteem among both sexes, despite sex differences in self-concept. The present study tests the applicability of Carlson's theory for a sample of gifted and talented female adolescents by examining three dimensions of possible self-esteem antecedents: actual talent ratings, self-perceptions of talent, and personality attributes. According to Carlson, talent ratings, self-perceptions, and personality attributes consistent with the feminine gender-role stereotype and a social orientation should emerge as positive predictors of the female adolescent's social self-esteem. Results of the regression analyses indicate that the best prediction of the social self-esteem of gifted and talented female adolescents is obtained from a combination of stereotypic feminine socially oriented and stereotypic masculine personally oriented predictor variables. For this sample, constructs such as androgyny appear to be more relevant to the understanding of social self-esteem than dichotomies such as personal-social orientation.

Pulmonary resection of metastatic renal cell carcinoma.

Over a ten-year period, 44 patients with known primary renal cell cancer underwent thoracotomy for pulmonary metastases. The median postthoracotomy survival for all patients was 33 months. The five-year survival was 27 percent. Postthoracotomy survival was significantly better in those patients with a disease free interval of greater than 24 months and patients with metastatic lesions greater than or equal to 3 cm. No difference in survival was detected in patients with one versus more than one lesion or in patients undergoing complete resection versus incomplete resection or biopsy only. Age, sex, grade of tumor, or location of the pulmonary metastasis had no influence on survival.
