How to measure segregation conditional on the distribution of covariates

This short paper proposes a nonparametric method for accounting for the distribution of background characteristics when testing for segregation in empirical studies. It is shown and exemplified – using data on workplace segregation between immigrants and natives in Sweden – how the method can be applied to correct any measure of segregation for differences between groups in the distribution of covariates by means of simulation and how analytical results can be used when studying segregation by means of peer group exposure.     

Discrepancies in pain presentation caused by adverse psychosocial conditions as compared to pain due to high physical workload?

Disorders in the musculoskeletal system have been associated with a high physical workload as well as psychosocial and individual factors. It is however not obvious which of these factors that is most important to prevent. Musculoskeletal disorders in neck and upper extremity was assessed by interview and clinical examination in 79 teachers and 93 assisting nurses, all females. Psychosocial work environment was assessed by questionnaire. The physical workload was recorded by technical measurements of postures, movements and muscular load, in 9 teachers and 12 nurses. The physical workload was lower among the teachers, but they had a more demanding psychosocial work environment. Among the nurses, but not in the teachers, the neck-shoulder disorders were associated with a high body mass index (BMI). The teachers reported neck-shoulder complaints to a higher extent than the nurses, but had much lower prevalence of diagnoses in the clinical examination (12% vs. 25%; POR 0.3 CI 0.1 - 1.2; adjusted for age and BMI). The results suggest that adverse psychosocial conditions among the teachers give rise to a different kind of pain in the neck-shoulder region than from physical overload, troublesome but not as severe as the one afflicting the nurses.     

Furniture dimensions and postural overload for schoolchildren's head, upper back and upper limbs

The aim of this study was to evaluate how the fixed furniture dimensions match with students' anthropometry and to describe head, upper back and upper limbs postures and movements. Evaluation was performed in 48 students from a Brazilian state school. Furniture dimensions were measured with metric tape, movements and postures by inclinometers (Logger Tecknologi, ?karp, Sweden). Seat height was high for 21% and low for 36% of the students; seat length was short for 45% and long for 9% and table height was high for 53% and low for 28%. Regression analysis showed that seat/popliteal height quotient is explained by 90th percentile of upper back inclination (β=0.410) and 90th percentile of right upper arm elevation (β=-0.293). For seat/thigh length quotient the significant variables were 90th percentile of upper back velocity (β=-0.282) and 90th percentile of right upper arm elevation (β=0.410). This study showed a relationship between furniture mismatch and postural overload. When the seat height is low students increase upper back left inclination and right upper arm elevation; when the seat is short students decrease the upper back flexion velocity and increase right upper arm elevation.     

Framing the tribal: ethnic violence in Northeast India

This article examines the framing of ‘ethnic conflict’ in Northeast India, focusing on militant groups and insurgency in the hill areas of Assam and a form of political violence known locally as ‘ethnic clashes’. The article argues that ‘ethnic clashes’ have become an institutionalized form of armed violence in the region, while ‘ethnic rivalry’ is a key diagnostic frame for conflict. As enactments and imaginaries of institutionalized violence, ‘ethnic clashes’ are a product of actors who hold stakes in representing armed political violence as a result of ‘ethnic conflict’ between rivaling tribal communities. The article looks at the representation of causes of conflict as well as the framing of acts of violence as key sites of contestation, and thus as integral aspects of the conflict. This raises questions about the feasibility of scholarly efforts to make sense of specific cases of conflict via generic categories such as the ‘ethnic conflict’.     

Truth and Indigenous Cosmopolitics in Shangrila

As this article shows, cadres involved in the ‘discovery’ of Shangrila in Yunnan were well aware of the fictional origins of the name. In arguments for changing the name of Zhongdian county to Xianggelila, scientific facts were coupled with literary truths about the Shangri-La of the 1930s novel Lost Horizon, grounded in material reality. In their efforts to make Shangrila meaningful locally, cadres associated Shangrila with the hidden land of Shambhala, appealing to a spiritual reality ultimately knowable only to visionaries. We can thus talk about three different logics of truth (scientific, literary and visionary) and two different realities (material and spiritual) of concern to the ‘making up’ of Shangrila.     

How to Maintain High Retention Rates in Long-Term Research on Addiction: A Case Report

High dropout rates threaten the validity of longitudinal studies involving participants suffering from substance use disorder (SUD). The objective of this article is to evaluate strategies to improve retention. The data analysis was based on an ongoing study of long-term recovery of neurocognitive and psychosocial functions. We used traditional strategies to enhance the contact rate. Common factors in psychosocial treatments and biweekly Short Message Service (SMS; text messaging) monitoring were added to further increase the contact rate. The participants (n = 146) were recruited from treatment facilities for SUD. Assessments were measured at 3 months, 6 months, 9 months, and 12 months. This study was successful in retaining a cohort of participants who are typically characterized as having a negative prognosis because of their unstable living arrangements and incomes. Compared to those using GHB, addictive medications, and opiates, the retention rate was the lowest among participants with severe alcohol use disorder (42%).     

What changes during specialized foster care? A study on adaptive functioning and emotional and social problems

Various models of specialized foster care have been developed, but research on them is limited. This longitudinal, exploratory study analysed data on adaptive functioning, emotional and social problems and self-concept in a specialized foster care service in Sweden. The focus of the study was on the development of the children and young people in placement. The Adaptive Behaviour Assessment System (ABAS-II) was used to measure adaptive functioning, and the Beck Youth Inventories of Emotional and Social Impairment (BYI) was used to measure self-rated emotional and social problems and self-concept. Self-ratings showed significant improvements in disruptive behaviour, anger, anxiety and depression. Adaptive functioning as rated by foster parents improved but not enough to catch up with the non-clinical norm group. The average adaptive functioning among the participants at baseline was considerably below the Swedish norm group. Similar to the results of a previous study of the same treatment model, children and young people rated improvement while their foster parents did not do so to the same extent. Possible explanations for this are discussed in the paper. The study is limited by the lack of a control group and by data attrition.
