Consequences of Family Policies on Childbearing Behavior: Effects or Artifacts?

This article argues for a more careful consideration of theoretical and methodological approaches in studies of the effects of public policies, labeled here as family policies, on childbearing behavior. We employ elements of comparative welfare‐state research, of the sociology of “constructed categories,” and of “the new institutionalism” to demonstrate that investigations into policy effects need to contextualize policies and need to reduce their complexity by focusing on “critical junctures,”“space,” and “uptake.” We argue that the effects of family policies can only be assessed properly if we study their impact on individual behavior. Event‐history models applied to individual‐level data are the state‐of‐the‐art of such an approach. We use selected empirical studies from Sweden to demonstrate that the type of approach that we advocate prevents us from drawing misleading conclusions.     

A precise estimator for the log-normal mean

The log-normal distribution is frequently encountered in applications. The uniformly minimum variance unbiased (UMVU) estimator for the log-normal mean is given explicitly by a formula found by Finney in 1941. In contrast to this the most commonly used estimator for a log-normal mean is the sample mean. This is possibly due to the complexity of the formula given by Finney. A modified maximum likelihood estimator which approximates the UMVU estimator is derived here. It is sufficiently simple to be implemented in elementary spreadsheet applications. An elementary approximate formula for the root-mean-square error of the suggested estimator and the UMVU estimator is presented. The suggested estimator is compared with the sample mean, the maximum likelihood, and the UMVU estimators by Monte Carlo simulation in terms of root-mean-square error.     

Effects of experimentally induced mental and physical stress on motor unit recruitment in the trapezius muscle

Mental stress may induce muscle tension and it is thought to contribute to the development of musculoskeletal disorders. Prolonged activity of a muscle's motor units (the smallest functional units) having low activation thresholds, may cause metabolic disturbances, degenerative processes and pain. The present experiment was aimed at investigating if the same motor units are activated by mental stress as by physical demands. Seventeen participants were exposed to mental stress tests (mental arithmetic, Stroop color word) and physical demands (standardized reference contraction, force ramp contraction) in the laboratory. In addition, they were exposed to the cold pressor test. Bipolar intramuscular electromyographic (EMG) activity was measured in the trapezius muscle, which covers the upper part of the back, the neck and the shoulder, and an automatic classification programme was used to separate the contributions of the individual motor units in the compex EMG signal. Overall muscle activity was measured by bipolar surface EMG and heart rate was recorded as an indicator of stress. The mental stress induced significant increases in muscle activity ( p < .05) and in heart rate ( p < .05). In 12 out of 14 participants, one or more motor units were found to be active in mentally as well as in physically induced muscle contraction. The results indicate that mentally induced stress may contribute to keeping low threshold motor units active, even in the absence of physical demands. Considering the health risks of prolonged motor unit activity, it was concluded that lack of mental rest is an important risk factor for the development of muscular pain.     

Fiducial and Posterior Sampling

The fiducial coincides with the posterior in a group model equipped with the right Haar prior. This result is generalized here. For this the underlying probability space of Kolmogorov is replaced by a σ-finite measure space and fiducial theory is presented within this frame. Examples are presented that demonstrate that this also gives good alternatives to existing Bayesian sampling methods. It is proved that the results provided here for fiducial models imply that the theory of invariant measures for groups cannot be generalized directly to loops: there exist a smooth one-dimensional loop where an invariant measure does not exist.     

Happy Living in Darkness! Indoor Lighting in Relation to Activities of Daily Living,Visual and General Health in 75-Year-Olds Living at Home

ABSTRACT

Lighting has been identified as a significant environmental attribute for promoting vision and general health among older people, enabling successful aging at home, but it has received little attention in the literature. Indoor lighting levels, self-reported vision and general health, and activities of daily life were measured in 114 healthy 75-year-old Norwegians. Despite very low levels of indoor lighting, the subjects were happy and healthy. There is a large discrepancy between self-assessed health and recommended lighting levels, and low awareness of the effect of lighting on age-related vision loss or daily living in the future. Knowledge of how to utilize indoor lighting to ensure healthy and safe aging in the home is needed.     

Mental health practice in primary care: Some perspectives concerning the future of social work in organized delivery systems

Abstract

The rise of managed care as the dominant form of healthcare delivery in the U.S. clearly has dramatic implications for the profession of social work. Thus far and for good reasons, the professional dialog about managed care has largely focused on . the threats posed to the professional agenda of social work by managed care in its various forms. This article considers some of the more positive aspects of the transformation from fee‐based to population‐based healthcare systems, in particular the vigorous trend toward multidisciplinary primary care and collaborative mental health practice in primary care settings. It is argued that the market forces behind this trend also promote the emergence of models of social work practice that better integrate historically dichotomized aspects of health and mental health practice. Also considered are implications for social work education and the division of labor among the healthcare professions.     

Gendering family composition: Sex preferences for children and childbearing behavior in the Nordic countries

It has been argued that a society's gender system may influence parents' sex preferences for children. If this is true, one should expect to find no evidence of such preferences in countries with a high level of gender equality. In this article, we exploit data from population registers from Denmark, Finland, Norway, and Sweden to examine continuities and changes in parental sex preferences in the Nordic countries during the past three to four decades. First, we do not observe an effect of the sex of the first born child on second-birth risks. Second, we detect a distinct preference for at least one child of each sex among parents of two children. For third births, Danish, Norwegian, and Swedish parents seem to develop a preference for having a daughter, while Finns exhibit a significant preference for having a son. These findings show that modernization and more equal opportunities for women and men do not necessarily lead to parental gender indifference. On the contrary, they may even result in new sex preferences.     

‘The Rotten Banana’ fires back: The story of a Danish discourse of inclusive rurality in the making

The popularity of a particular term – the Rotten Banana – has paralleled the one-sided centralisation of public services since the Danish Municipal Reform of 2007. The Rotten Banana denotes peripheral Denmark, which takes a geographically curved form that resembles a banana, and it symbolises the belief that rural areas are backward and (too) costly. This article shows how the negative connotations of rural areas have come to outweigh the positive ones and to legitimise liberal visions of the ‘sustainable’ welfare state. Whereas previous studies on the perceptions of rural dwellers have focused on the discourses of rurality that produce rural outsiders, this article builds on the work of de Certeau and of Laclau and Mouffe. Based on both quantitative and qualitative data, the study shows how, in Denmark, negative connotations and centralisation have together spurred a new and political mobilisation in many parts of the ‘banana’. Through skilful ‘consumption’, rural dwellers have adapted the alienating liberalist ‘logic of equivalence’ to their own use and produced a ‘logic of difference’, thus challenging the predominant political discourse of rurality. As a result, the Danish Liberal government was forced to introduce a new and more inclusive rural policy in September of 2010 and grant rural dwellers a political voice in parliament.
