Exploring approaches to child welfare in contexts of domestic violence and abuse: Family group conferences

This article sets out to explore service provision for families affected by domestic violence and abuse. For most families where there are child protection concerns, there are possibilities for intervention from child welfare agencies and domestic abuse services, but these have been criticised as having distinct and disconnected practice cultures and orientation. Recognising this divergence, in this paper, we advocate for safeguarding children affected by domestic violence and abuse using the family group conference (FGC) model. This offers possibilities for a coherent response that integrates both child‐ and women‐centred concerns in a holistic approach to family safety and well‐being. Furthermore, it is well documented that safeguarding work involves professionally‐led decision‐making that is pre‐occupied with the management of risk. FGCs, however, promote a partnership approach that engages families in a more democratic decision‐making process. As such, FGCs offer families the opportunity to develop their own safety and support plans for the protection and care of children recognising the family's inherent strengths.     

Modeling Lung Carcinogenesis in Radon‐Exposed Miner Cohorts: Accounting for Missing Information on Smoking

Epidemiological miner cohort data used to estimate lung cancer risks related to occupational radon exposure often lack cohort‐wide information on exposure to tobacco smoke, a potential confounder and important effect modifier. We have developed a method to project data on smoking habits from a case‐control study onto an entire cohort by means of a Monte Carlo resampling technique. As a proof of principle, this method is tested on a subcohort of 35,084 former uranium miners employed at the WISMUT company (Germany), with 461 lung cancer deaths in the follow‐up period 1955–1998. After applying the proposed imputation technique, a biologically‐based carcinogenesis model is employed to analyze the cohort's lung cancer mortality data. A sensitivity analysis based on a set of 200 independent projections with subsequent model analyses yields narrow distributions of the free model parameters, indicating that parameter values are relatively stable and independent of individual projections. This technique thus offers a possibility to account for unknown smoking habits, enabling us to unravel risks related to radon, to smoking, and to the combination of both.     

Toward a critical sociology of lifestyle migration: reconceptualizing migration and the search for a better way of life

This article places under critical and reflexive examination the theoretical underpinnings of the concept of lifestyle migration. Developed to explain the migration of the relatively affluent in search of a better way of life, this concept draws attention to the role of lifestyle within migration, alongside understandings of migration as one stage within the ongoing lifestyle choices and trajectories of individual migrants. Through a focus on two paradigms that are currently at work within theorizations of this social phenomenon – individualization and mobilities – we evaluate their contribution to this flourishing field of research. In this way, we demonstrate the limitations and constraints of these for understanding lifestyle migration; engaging with long‐standing debates around structure and agency to make a case for the recognition of history in understanding the pursuit of ‘a better way of life’; questioning the extent to which meaning is made through movement, and the politics and ethics of replacing migration with mobilities. Through this systematic consideration, we pave the way for re‐invigorated theorizing on this topic, and the development of a critical sociology of lifestyle migration.     

Does the female cycle matter? Looking at aggressive intentions after social exclusion*

Excluded people vary in their coping with social pain. The menstrual cycle has shown to moderate experiences related to pain. We therefore investigated the influence of the menstrual cycle on aggressive intentions in response to social exclusion. Results revealed no effect of the menstrual cycle alone. However when exploratory taking dispositional social anxiety into account, we found women low in social phobia to report more aggression in response to social exclusion in the luteal than in the non-luteal phase. In this phase, they indicated a similarly high aggression level than women high in social phobia who did not differ between the luteal and non-luteal phase. These findings are discussed within the framework of evolutionary adaption.     

Job Displacement and First Birth Over the Business Cycle

In this article, we investigate the impact of job displacement on women’s first-birth rates as well as the variation in this effect over the business cycle. We use mass layoffs to estimate the causal effects of involuntary job loss on fertility in the short and medium term, up to five years after displacement. Our analysis is based on rich administrative data from Germany, with an observation period spanning more than 20 years. We apply inverse probability weighting (IPW) to flexibly control for the observed differences between women who were and were not displaced. To account for the differences in the composition of the women who were displaced in a downturn and the women who were displaced in an upswing, we use a double weighting estimator. Results show that the extent to which job displacement has adverse effects on fertility depends on the business cycle. The first-birth rates were much lower for women who were displaced in an economic downturn than for those who lost a job in an economic upturn. This result cannot be explained by changes in the observed characteristics of the displaced women over the business cycle.     

Parameter Estimation for Inhomogeneous Space‐Time Shot‐Noise Cox Point Processes

We consider the problem of parameter estimation for inhomogeneous space‐time shot‐noise Cox point processes. We explore the possibility of using a stepwise estimation method and dimensionality‐reducing techniques to estimate different parts of the model separately. We discuss the estimation method using projection processes and propose a refined method that avoids projection to the temporal domain. This remedies the main flaw of the method using projection processes – possible overlapping in the projection process of clusters, which are clearly separated in the original space‐time process. This issue is more prominent in the temporal projection process where the amount of information lost by projection is higher than in the spatial projection process. For the refined method, we derive consistency and asymptotic normality results under the increasing domain asymptotics and appropriate moment and mixing assumptions. We also present a simulation study that suggests that cluster overlapping is successfully overcome by the refined method.     

Functional Elements in Infants' Speech Processing: The Role of Determiners in the Syntactic Categorization of Lexical Elements

How do children determine the syntactic category of novel words? In this article we present the results of 2 experiments that investigated whether German children between 12 and 16 months of age can use distributional knowledge that determiners precede nouns and subject pronouns precede verbs to syntactically categorize adjacent novel words. Evidence from the head‐turn preference paradigm shows that, although 12‐ to 13‐month‐olds cannot do this, 14‐ to 16‐month‐olds are able to use a determiner to categorize a following novel word as a noun. In contrast, no categorization effect was found for a novel word following a subject pronoun. To understand this difference we analyzed adult child‐directed speech. This analysis showed that there are in fact stronger co‐occurrence relations between determiners and nouns than between subject pronouns and verbs. Thus, in German determiners may be more reliable cues to the syntactic category of an adjacent novel word than are subject pronouns. We propose that the capacity to syntactically categorize novel words, demonstrated here for the first time in children this young, mediates between the recognition of the specific morphosyntactic frame in which a novel word appears and the word‐to‐world mapping that is needed to build up a semantic representation for the novel word.
