Diversity management in preschools using a critical incident approach

Using the critical incident approach, preschool teachers at 10 preschools in Sweden were asked to describe their work with respect to ethnic and cultural diversity. The study attempted to provide insights that go beyond commonly used models of intercultural sensitivity and intercultural competence (e.g. Gudykunst and Kim; Landis, Bennett, and Bennett). Four different understandings and approaches to ethnic and cultural diversity were discernible in the empirical material (i.e. ‘instrumental,’ ‘co-productive,’ ‘facilitative proactive,’ and ‘agitative proactive’). The data suggest that preschool teachers, in order to be interculturally competent, need to work systematically with intercultural pedagogy, intercultural communication skills, and with their discursive awareness. Moreover, it is concluded that if preschool teachers fail to scrutinize their own values, modes of behavior, and a-priori understanding of what ‘is’ cultural behavior, they may sustain cultural stereotypes.     

The Contribution of Assisted Reproduction to Completed Fertility: An Analysis of Danish Data

Assisted reproduction has a minor but increasing influence on childbearing trends in advanced societies. In Denmark, the use of assisted reproduction technology (ART) has become particularly widespread. At the same time, Danish women born in the late 1950s and the 1960s experienced stabilization or even a slight increase in their mean number of children. Broad availability and widespread use of assisted reproduction may become important factors contributing to maintaining relatively high completed fertility among the younger cohorts of Danish women. To explore this idea, we analyze and project cohort trends in fertility rates among native Danish women born in 1960‐78 and examine the likely contribution of assisted reproduction to these trends. The projected proportion of children born after ART treatment shows a substantial increase from 2.1 percent among women born in 1965 to 4‐5 percent among women born in 1978, with an estimated net impact of ART (as compared with the hypothetical situation where no ART treatment was available) on the order of 3‐4 percent. When intrauterine inseminations are included, this implies that up to 7 percent of children of those native Danish women born in 1975 and later will likely be conceived by infertility treatment.     

Social Closure and Educational Attainment

This article examines how network closure among parents affects adolescents’ educational attainment. First, we introduce a distinction between informal closure and school‐based closure. Second, we investigate whether and how the effect of informal and school‐based parental network closure varies across social contexts. Findings from the National Longitudinal Study of Adolescent Health (Add Health) and multilevel models show that parental network closure modestly impacts educational outcomes. Moreover, educational benefits of informal closure in parent networks are contingent on social context. Closure only benefits educational attainment in low‐poverty schools. In high‐poverty schools, informal closure in parent networks lowers educational attainment. The social closure generated in informal connections among parents thereby contributes to the encapsulation of disadvantage in areas of concentrated poverty, which is not the case for school‐based closure.     

Lower bone mineral density in older female endurance skiers – a cross-sectional,observational study

Background

Physical activity (PA) is generally beneficial for bone health, but the effect of high levels of PA over many years, in older women, is unknown.

Methods

T-score from Dual-energy X-ray absorptiometry (DXA), and self-reported baseline characteristics were recorded for 24 female, cross-country-skiing-competitors, aged 68–76?years, from the Birkebeiner Ageing Study. Data from 647 women in the same age range from the Tromso-6 population study, with recorded DXA findings, were used for comparison.

Results

The athletes reported a median(range) of 9(1–34) participations in the 54?km, yearly ski-race, indicating long-term PA. They also reported more moderate and high levels of PA than women in the general population (52% vs. 12 and 30% vs. 0%, respectively). The athletes had lower body mass index (BMI) than the controls (mean BMI 21.7 vs 26.9?kg/m², p?<?0.001). As many as 22/24(92%) of the athletes and 477/647(74%) of the controls had a low bone mineral density (BMD) (T-score?<???1), p 0.048, Pearson chi square test. Odds ratio (OR) of low BMD was 3.9 in athletes vs. controls (p 0.048, logistic regression), but adjusting for BMI largely diminished the effect estimate, which was no longer statistically significant (aOR 1.81, p 0.432). The proportion of self-reported fractures was the same in the two groups.

Conclusions

This pilot study suggests that long-term, high levels of PA are associated with low bone mineral density in older women, and the finding might be due to differences in BMI. Despite the lower bone mineral density the athletes did not report more fractures.
