Three groups of 60 22- to 28-yr.-old males, matched for age, socio-economic status and scholastic aptitude and classified as hard core unemployables were tested on the Rotter I-E Scale. No significant differences in alienation scores were noted between Group A whites and white college students. Group B Black Ss were significantly more externally controlled with greater variability of scores. Group C Mexican-Americans showed an even greater tendency in the external direction and greater variability than the others. Blacks and Mexican-Americans did not differ significantly in expression of external control. Lack of feeling for any relation between individual effort and reward may account for the difficulty in equipping these groups with knowledge and skill to improve their lot.

Considering that learning is heavily focused on the acquisition of knowledge, it is important to examine the individual and systematic implications of these types of knowledge. Purpose: The purpose of this study was to examine the impact on overall educational performance as a result of engaging with technology subjects at post-primary level. Sample: A five year cohort study was designed to gather longitudinal data from a total sample of 1761 pupils' grades from the Irish Leaving Certificate examination. The sample was distributed across four schools. Design and methods: Grades from the Irish Leaving Certificate were selected because the examination is considered high stakes as it serves as the country's primary mechanism for matriculation into third-level education. Individual examinations are designed externally to schools by a government body ensuring the validity of each examination in capturing the holistic interpretation subject syllabi. Finally, a points system is used to score each examination facilitating comparisons between subjects.
Results:The results show that pupils who study the technology subjects are statistically significantly less likely to perform well overall in comparison to pupils who study science and mathematics subjects. They also show that for pupils who study the technology subjects, those subjects are statistically significantly likely to be their best performing subjects. Conclusions: Due to the array of variables impacting subject selection, a definitive causal explanation cannot be deduced from the data for these results. However, it is possible to infer that the variance in knowledge types between the science and technology subjects has an impact on the results. A case is made that a compulsory technological component should be incorporated into educational curricula to provide a comprehensive and general education and to facilitate the holistic development of pupils.
A longitudinal diagnostic assessment based on multiple sources of information is crucial for categorizing first-admission psychotic patients, particularly those who do not initially fit into a DSM-III-R category. The short-term stability of a diagnosis is a function of multiple factors, including the changing clinical picture, additional sources of information, and new interpretations of original data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
