How does cultural capital affect educational performance: Signals or skills?

In this paper, we test two mechanisms through which cultural capital might affect educational performance: (a) teachers misinterpreting cultural capital as signals of academic brilliance and (b) cultural capital fostering skills in children that enhance educational performance. We analyse data from the ECLS-K and ECLS-K:2011 from the United States and focus on three aspects of children’s cultural capital: participation in performing arts, reading interest and participation in athletics and clubs. We find that (1) none of the three aspects of cultural capital that we consider affects teachers’ evaluations of children’s academic skills; (2) reading interest has a direct positive effect on educational performance; and (3) the direct effect of reading interest on educational performance does not depend on schooling context. Our results provide little support for the hypothesis that cultural capital operates via signals about academic brilliance. Instead, they suggest that cultural capital fosters skills in children that enhance educational performance. We discuss the theoretical implications of our findings.     

An analysis of vendor innovation capability in the contract electronics manufacturing industry

Limited academic research has been given to analysing the innovation capabilities of vendors in outsourcing contracts. This paper seeks to address this gap in the literature by enhancing our understanding of how the innovation capability of vendors is deployed to win, run and renew outsourcing contracts with their customers. Employing the resource-based view as a theoretical basis and undertaking in-depth case study analysis of three vendors in the electronic manufacturing services industry, the research shows that to achieve the outsourcing objectives of winning, running and renewing the contract, vendors can use different configurations of the competitive priorities of cost, quality, delivery and flexibility. The research aggregates the capabilities that influence the innovative capability of a vendor into the innovation-related capabilities (IRCs) of design, new product introduction and manufacturing. Three strategies are identified for vendors on how to deploy these IRCs, and a number of propositions are developed to indicate the suitability of the three deployment strategies for different operational contexts.     

Temporal stability of entries and predictors for entry into out-of-home care before the third birthday: A Danish population-based study of entries from 1981 to 2008

Objective

Placing a child in out-of-home care is one of the most radical measures a child protection system can decide to take. There is an essential interest in understanding the probability of entering care and what circumstances are related to the decision to place a child in out-of-home care. This study investigates the temporal stability of rates and predictors for entry into care.

Method

Data were obtained by linking several registration systems. The study population was defined as all children entering care before their third birthday from birth cohorts 1981–2008 (N = 11,034). Furthermore, a control population consisting of a randomly assigned quarter of the Danish child population from the same birth cohorts was used (N = 515,773). Rates of entry and Cox regression models from six periods from 1981 to 2008 were used to model co-variates associated with entry into out-of-home care.

Results

The overall likelihood for entering care is found to be decreasing over time. Furthermore, results reveal two trends: relative rates of entry are significantly decreasing for children whose mother has a psychiatric history prior to the child's birth; relative rates are significantly increasing for children whose mother or father was unemployed in the year prior to the child's birth.     

USE OF A LOG-LINEAR MODEL TO COMPUTE THE EMPIRICAL SURVIVAL CURVE FROM INTERVAL-CENSORED DATA, WITH APPLICATION TO DATA ON TESTS FOR HIV POSITIVITY

We describe how a log-linear model can be used to compute the nonparametric maximum likelihood estimate of the survival curve from interval-censored data. This permits such computation to be performed with the aid of readily available statistical software such as GLIM or SAS. The method is illustrated with reference to data from a cohort of Danish homosexual men, each of whom was tested for HIV positivity on one or more of six possible follow-up times.     

Outlier detection in contingency tables using decomposable graphical models

For high-dimensional data, it is a tedious task to determine anomalies such as outliers. We present a novel outlier detection method for high-dimensional contingency tables. We use the class of decomposable graphical models to model the relationship among the variables of interest, which can be depicted by an undirected graph called the interaction graph. Given an interaction graph, we derive a closed-form expression of the likelihood ratio test (LRT) statistic and an exact distribution for efficient simulation of the test statistic. An observation is declared an outlier if it deviates significantly from the approximated distribution of the test statistic under the null hypothesis. We demonstrate the use of the LRT outlier detection framework on genetic data modeled by Chow–Liu trees.

Work & stress: Information

The aim of this study was to investigate whether psychosocial factors at work are related to low-back pain among nursing personnel. It was conducted as a short-term follow-up study of 200 Danish female nursing personnel, providing care for the elderly. Self-reported measures of psychosocial factors such as time pressure, emotional demands of clients, control and social support were obtained by questionnaire at baseline, while stress, physical exertion and low-back pain were reported by diary records made in two, three-day periods in the subsequent 6 months. The study examines the possible influence of psychosocial factors preceding low-back pain as well as stress and physical exertion reported simultaneously with low-back pain. Only stress was associated with low-back pain (Odds Ratio (OR)=2.3; Confidence Interval (CI)=1.3-3.9) while neither physical exertion or any of the psychosocial factors were related to low-back pain. A possible pathway connecting emotional demands of clients to low-back pain through the mediation of stress was suggested.     

Incomplete equalization: The effect of tracking in secondary education on educational inequality

This paper tests whether the existence of vocationally oriented tracks within a traditionally academically oriented upper education system reduces socioeconomic inequalities in educational attainment. Based on a statistical model of educational transitions and data on two entire cohorts of Danish youth, we find that (1) the vocationally oriented tracks are less socially selective than the traditional academic track; (2) attending the vocationally oriented tracks has a negative effect on the likelihood of enrolling in higher education; and (3) in the aggregate the vocationally oriented tracks improve access to lower-tier higher education for low-SES students. These findings point to an interesting paradox in that tracking has adverse effects at the micro-level but equalizes educational opportunities at the macro-level. We also discuss whether similar mechanisms might exist in other educational systems.
