When do people accept cultural diversity?: Affect as determinant

Two experiments examined the influence of affect on the acceptance of cultural diversity. In Experiment 1, the salience of affective reactions towards Turkish immigrants was manipulated by asking German participants to think about their negative feelings towards Turks in general or towards a subgroup of Turks. It was found that the salience of negative affective reactions led to a decreased acceptance when affective reactions were generalized to the whole group, but not when they were attributed to a subgroup. Experiment 2 investigated the moderating role of perceived homogeneity with regards to the impact of affective reactions attributed to a subgroup of Muslim immigrants in Germany. As predicted, the salience of a negative aspect of a subgroup strengthened self-reported and implicitly measured negative attitudes when the perceived homogeneity of the immigrant group was high, but not when it was low.     

Classroom Animals Provide More Than Just Science Education

Keeping classroom animals is a common practice in many classrooms. Their value for learning is often seen narrowly as the potential to involve children in learning biological science. They also provide opportunities for increased empathy, as well as socio-emotional development. Realization of their potential for enhancing primary children’s learning can be affected by many factors. This paper focuses on teachers’ perceptions of classroom animals, drawing on accounts and reflections provided by 19 participants located in an Australian primary school where each classroom kept an animal. This study aims to progress the conversation about classroom animals, the learning opportunities that they afford, and the issues they present. Phenomenographic analysis of data resulted in five categories of teachers’ perceptions of the affordances and constraints of keeping classroom animals.     

A rationale for differentiated staffing

The improvement of staff utilization practices through the technique of differentiated staffing is the subject of this paper. The authors bring together the various definitions of the term differentiated staffing and propose a more inclusive definition. Drawing from the literature in organizational change, the authors document in a logical and systematic manner the parameters of differentiated staffing and the problems that are likely to be associated with its introduction. The major part of the paper analyzes the potential of differentiated staffing for improving many deficiencies that are apparent in present methods of utilizing professional personnel in the public schools and in the decision-making procedures of those organizations. The authours urge controlled and systematic pilot projects be undertaken before largescale or even system-wide adoption.

Résumé Le sujet de cette étude porte sur l'amélioration des méthodes d'utilisation du personnel au moyen de la technique de la différenciation du personnel. Les auteurs regroupent les diverses définitions de l'expression différenciation du personnel et proposent une définition plus globale. En s'inspirant des documents relatifs aux changements structuraux en matière d'organisation, les auteurs appuient sur des documents, d'une manière logique et systématique, leur idée des paramètres de la différenciation du personnel et des problèmes qui vraisemblablement accompagneront sa mise en application. Cette étude est consacrée principalement à l'analyse des possibilités qu'offre la différenciation du personnel en vue d'améliorer les nombreuses lacunes que l'on constate à l'égard des méthodes actuelles d'utilisation du personnel qualifié dans les écoles publiques et au niveau des méthodes de prise de décision des ces organismes. Les auteurs préconisent le recours à des projets pilotes méthodiques et bien dirigés avant que cette nouvelle technique soit adoptée sur une vaste échelle ou même à celle du système.

A comparison of the development of spatial conceptual abilities of students from two cultures

Efforts are underway to determine if there are any ways unique to Navajo thinking and thus to the way that they might learn. Studies have shown a consistent lag in achievement levels for Native Americans. The purpose of this investigation was to examine spatial thinking abilities of sixth and tenth grade students from 2 locales—a school on the Navajo Reservation and schools in Mesa, Arizona. A battery of 10 Piagetian-type tasks were administered individually to the subjects. A chi-square one sample procedure was used to test for significant differences between subsamples at each grade level. Significant differences were detected for two of the tasks at the sixth grade level, and one task at the tenth grade level. The overall findings of this study support the contention that there were no substantial time delays or advances in the development of selected spatial abilities of Navajo sixth and tenth grade students compared to those of parallel non-American Indian students. The concern of modifying instruction in science courses in order to adapt them to supposed 'different' spatial structures possessed by Navajo students appears to be unfounded.     

Moving Beyond a Deficit Model to Describe and Promote the Career Development of At-Risk Youth

A theoretical framework for understanding the career maturity of diverse groups is needed since the career maturity construct has evolved using white, middle class samples (Cheatham, 1990). Krumboltz holds that career beliefs can be influenced by one's social environment (1991). If career beliefs were related to the career maturity of a diverse group, they could be used to provide a more coherent understanding of the unique social experiences that surround their career maturity. This study examined relationships between the career beliefs and the career maturity of academically at-risk students who were failing core academic courses. Several career beliefs were significantly related to the career maturity of the sample in this study such as the belief that obstacles can be overcome and college/occupation variation. The career beliefs construct appeared to clarify the role that social experiences played on the career maturity of the sample in this study.     

Individually Weighted-Average Models: Testing a Taxonomic SEM Approach Across Different Multidimensional/Global Constructs Because the Weights “Don’t Make No Nevermind”

From the time of William James, psychologists have posited individually importance-weighted-average models (IWAMs) in which weighting specific attributes by individual measures of importance improves prediction of the global outcome measures. Because IWAMs cause much confusion, we briefly review a general taxonomic paradigm and structural equation models for testing IWAMs, and demonstrate its application for 2 simulated and 3 diverse “real” data applications (multidimensional measures of self-concept, quality of life, and job satisfaction). Consistent across the real data applications and previous research more generally, there is surprisingly little support for IWAMs when tested appropriately. In these diverse tests of IWAMs we integrate new approaches such as exploratory structural equation modeling (SEM), alternative approaches to constructing latent interactions, application of bifactor models, modeling method and item-wording effects, and the juxtaposition of model evaluation in relation to goodness of fit (typically used in SEM studies) and variance explained (typically used in multiple regression tests of IWAMs).     

Factors Influencing the Wear Behavior of Sintered Steels

A review was made on the research progress of wear behavior of sintered steels in recent years.Wear is not an intrinsic property of sintered steels,which is strongly influenced by the wear test conditions.Howerver,many other factors that determine the mechanical properties of sintered steels also affect the wear behavior.Porosity has different effects on the wear of sintered steels depending on the application conditions.Under dry sliding condition ,higher porosity results in lower wear resistance.The influence of microstructures on wear resistance is in the order;Carbide,martensite,bainite and lamellar pearlite,The wear resistance increases with hardness,but this relationship changes with the porosity and microstructures of sintered steels.
