The Materialisation of School in Families' Everyday Lives

This article explores how school is materialised within Danish families and the significance for both children and parents. Based on ethnographic research and inspired by materiality studies and by family and childhood studies, the analysis describes how school-related objects, such as schoolbags, actualise school within the family and create intensive ‘school parenting’. The article also illustrates how the materialisation of school both entangles with family routines, becoming part of being a family and feeds into processes of demarcation and ways of reducing the importance of school in family routines.     

Alternatives to post‐processing posterior predictive p values

The posterior predictive p value (ppp) was invented as a Bayesian counterpart to classical p values. The methodology can be applied to discrepancy measures involving both data and parameters and can, hence, be targeted to check for various modeling assumptions. The interpretation can, however, be difficult since the distribution of the ppp value under modeling assumptions varies substantially between cases. A calibration procedure has been suggested, treating the ppp value as a test statistic in a prior predictive test. In this paper, we suggest that a prior predictive test may instead be based on the expected posterior discrepancy, which is somewhat simpler, both conceptually and computationally. Since both these methods require the simulation of a large posterior parameter sample for each of an equally large prior predictive data sample, we furthermore suggest to look for ways to match the given discrepancy by a computation‐saving conflict measure. This approach is also based on simulations but only requires sampling from two different distributions representing two contrasting information sources about a model parameter. The conflict measure methodology is also more flexible in that it handles non‐informative priors without difficulty. We compare the different approaches theoretically in some simple models and in a more complex applied example.     

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.

     

Two cultures: one life

Recognition of the communal nature of the culture and traditionsof many refugees who have resettled in Australia in recent years,particularly those from African countries, has urged a strongerconsideration of community-based approaches to their recoveryand resettlement. In 2004, a framework of recovery, developedto enhance the mental health and well-being of refugees duringresettlement in Australia, was applied to a community capacity-buildingprogramme among South Sudanese refugees living in an outer westernsuburb of Melbourne. This paper explores the integration ofrecovery goals into the structures and processes initiated throughoutthe programme. It assesses the contribution of this model tostrengthening the community's ability to adjust to resettlementand enable greater control in determining their lives in Australia.     

Does Frequency of Interruptions Amplify the Effect of Various Types of Interruptions? Experimental Evidence

The aim of this experiment was to determine if the frequency of interruptions during an interaction amplifies the effect of the type of the interruptions on the interruptee (the amplification hypothesis). While interviewing 90 participants, two confederates manipulated four different kinds of interruptions (change-subject, same-subject, disagreement, and supportive interruptions) at two different frequencies (mean rates, 1.58 and 2.94 per minute), in addition to a no-interruption control condition. At the end of the interview, the participants were asked to answer questions about themselves, the interlocutor, and the situation. The results showed that the negative effects of change- and same-subject interruptions were amplified when they were more frequent, as were the positive effects of supportive interruptions. Contrary to expectations, disagreement interruptions were regarded as positive. All the results provide support for the amplification hypothesis.     

“Living Together” as a Developmental Phase: A Holistic View*

“Living together” is examined not simply as a new cultural variant or trial marriage but as the effort of some young adults, particularly on campus, to deal with several fundamental aspects of moving from childhood to adulthood, or an additional “rite de passage.” It seems that increasingly many young people are trying to deal with the tasks and marked discontinuity in our culture between childhood and adulthood by this new open arrangement. To evaluate and respond appropriately to this transitional solution, the adult community-college authorities, parents, counselors, and others-might find it helpful to view holistically the many developmental tasks which must be dealt with simultaneously during this process. So viewed, “living together” can be seen as a creative solution for some rather than as “moral disintegration.”     

Interpretation of dispersion effects in a robust design context

The purpose of this paper is to discuss the interpretation of dispersion effects in un-replicated fractional factorials from a robust design perspective. We propose an interpretation of dispersion effects as manifested interactions between control factors and unobserved and uncontrolled factors, an interpretation shown to be useful in achieving robust designs. Further, we show the consequences this interpretation has on the identification of dispersion effects.     

Fifty Years of the Southern Sociological Society: Change and Continuity in a Professional Society. Methodological Perspectives on Studying the History of the Southern Sociological Society

This paper revisits research procedures used to collect and analyze data for Fifty Years of the Southern Sociological Society: Change and Continuity in a Professional Society (1988) to comment on methodological issues. The fifty years of change were conceptualized as having shifted the Southern Sociological Society from a disciplinary to a professional mode of organization. The shift occurred both from evolutionary processes and from deliberate revolutionary actions of officials and members. Data for the study came mainly from the Society’s Archives. It included personal accounts by presidents, secretary-treasurers’ and committee reports, annual programs and newsletters. Evolutionary processes of adapting the association to the growth of membership, to differentiation of fields of sociological study, along with the rationalization and formalization of the Society’s governance and operation, were extracted mainly from annual programs, the most continuous and objective body of archival information. Revolutionary changes, including adaptation to societal challenges including racial segregation, from the Society’s founding onward were inferred from personal accounts, committee reports, and newsletters, and were confirmed from interviews with long-standing members.
