L'Education Des Enfants Des Travailleurs Migrants En Suisse

Swiss policy vis-à-vis children of migrant workers has two objectives: promoting their integration in the Swiss educational system and permitting to a certain extent, efforts to preserve their linguistic and cultural identity. The authors analyse the policy measures and their educational objectives for each stage of education.     

Creative block play

Blocks should be part of the daily free choice activity in early childhood settings for children between the ages of two and six. Large enough segments of time need to be allotted for blockbuilding activities, so that children can build various structures and also have enough time to use blocks for social and dramatic play.

The second face of systems integration: An empirical analysis of supply chains to complex product systems

Systems integration encompasses both system design and management of supplier networks. We examine the “second face” of systems integration related to the organization and management of supplier networks. We analyze a unique dataset on the supply chains for three major U.S. weapon systems to examine how systems integrators balance the economies-of-scope benefits of general-purpose technologies and the benefits of horizontal supplier specialization. We show that horizontal specialization – an establishment’s focus on a particular market – differs with distance from the systems integrator. Systems integrators derive the benefits of specialization primarily (though not exclusively) from their direct suppliers, and they access general-purpose technologies from lower-tier suppliers. Some of the lower-tier suppliers themselves integrate complex subsystems, belying the image of the supplier network as a “production pyramid” with simple firms at its base. We further find that the supply chains of the three weapon systems that we study are dominated by facilities whose main line of business is in non-defense markets, because of the large number of lower-tier suppliers that serve commercial markets. This demonstrates the importance of the supply chain as a source of commercial-military integration, linking defense production to the wider economy and casting doubt on the view that there is a “wall of separation” that prevents the U.S. defense effort from gaining access to civilian technologies.     

Health benefits of Kung Fu: a systematic review

The Chinese martial arts (Kung Fu) have existed for centuries and are generally accepted as being beneficial for health without much empirical data. The aim of this systematic review was to assess the health effects of "hard" Kung Fu styles by performing electronic and manual searches of the literature. The aspects of health and the Kung Fu style examined varied between most studies; in some cases, the martial art group consisted of practitioners of other martial art styles also. Of 2103 references identified, only nine papers were eligible and reviewed. All were observational studies, observing a range of health aspects possibly related to Kung Fu training or performance. Our findings suggest that there is no evidence that Kung Fu practice is associated with the prevention or treatment of any health condition. However, as a moderate- to high-intensity form of aerobic exercise, it may confer benefits similar to those attributed to other aerobic training modalities. However, this hypothesis remains to be tested in clinical trials. Physiological benefits (e.g., aerobic capacity and bone density) may be associated with long-term Kung Fu practice. Future research in this area should adopt experimental designs, clearly identifying eligibility criteria, testing and training protocols, and include health-related outcomes and documentation of adverse events, to advance knowledge in this field.     

The relationship between social behavior and self-concept in school settings

The relationship between social behavior, as measured by the School Social Behavior Scales (SSBS), and self-concept, as measured by the Self-Perception Profile for Children (SPPC), was studied. Subjects included 41 public school students in Grades 5 and 6. These subjects were rated on the SSBS by their classroom teachers and also completed the SPPC as a self-report measure. A number of significant positive relationships were found between the Social Competence scores of the SSBS and the SPPC self-concept scores. Relationships between the Problem Behavior scores of the SSBS and the SPPC scores were extremely weak, and none of the obtained coefficients was statistically significant. The pattern of associations identified through this investigation provides support for the criterion-related validity of both the SSBS and SPPC, and raises some interesting questions regarding the relationship between social behavior and self-concept in children.     

Effects of developmental relationships with teachers on middle-school students’ motivation and performance

We examined how middle-school students’ motivation, belonging, school climate, and grade point average (GPA) are affected by students experiencing developmental relationships—those that go beyond teachers being caring (e.g., showing warmth to students) and providing challenge (e.g., high expectations) to also include teachers providing support, sharing power, and expanding students’ sense of possibilities. We also examined variations in those associations by student socioeconomic status (SES). The study included 534 diverse Grades 6–8 students (51% female, 46% non-White, 33% eligible for free and reduced price meals). Structural equation modeling and regressions showed that students with better developmental relationships with their teachers had better outcomes. Developmental relationships strongly predicted academic motivation at both the beginning and end of the school year, and also directly predicted students’ sense of belonging and school climate. Relationships indirectly predicted GPA, through motivation. Student–teacher relationship quality for low-SES students was lower and declined more than for other students. The results both reflect current literature in showing the importance of strong student–teacher relationships, and extend it in showing the worsening relationships quality for low-income students, and in suggesting that strengthening multiple facets of student–teacher developmental relationships may have important effects on motivation and achievement of middle-school students.
