The changing relationship between unemployment and total fertility

The aim of this paper is to investigate whether there has been a fundamental change in the relationship between economic conditions and fertility. We use panel data methods to study the short-term changes in total fertility and the unemployment rate in a range of Organisation for Economic Co-operation and Development (OECD) countries from 1957 to 2014. We find that although fertility was counter-cyclical before 1970, with good economic times being associated with lower fertility, since then it has become pro-cyclical, with good economic times being associated with higher fertility.     

Work–Family Conflict,Job Insecurity,and Health Outcomes Among US Workers

Previous scholarship has highlighted how work–family conflict (work-to-family conflict and family-to-work conflict) and job insecurity interfere with health outcomes. Little work, however, considers how these stressors jointly influence health among workers. Informed by the stress process model, the current study examines whether job insecurity moderates the relationships between work-to-family conflict and family-to-work conflict and two health outcomes: self-reported physical health and poor mental health. The analyses also consider whether a greater moderating role is played by work-to-family conflict or family-to-work conflict. Using data from the 2008 National Study of the Changing Workforce, we also examine if patterns diverge by gender. Our results show that work-to-family conflict and family-to-work conflict have direct effects on poor mental and physical health. Additionally, we find that the negative effect of work-to-family conflict on poor mental and physical health is stronger for those with job insecurity, while no such relationship was found for family-to-work conflict. We found no evidence of significant gender differences in how these relationships operate. Overall, we contribute to the literature by testing the combined effects of both forms of work–family conflict and job insecurity on poor mental and physical health. We also deepen the understanding of the stress process model by highlighting the salience of the anticipatory stressor of job insecurity.     

Framing Syrians in Turkey: State Control and No Crisis Discourse

The mass arrival of Syrian refugees and their continuing presence have triggered many new debates regarding migration in Turkey, which – as a result of its open-door policy – now hosts the highest number of refugees in the world. Yet, when we investigate the ways political institutions and actors have framed migration, we observe, unlike in European discourses, the complete absence of the word “crisis”. In public statements by politicians, “control” emerges instead as a recurrent (albeit implicit) theme. Here, management of the refugee issue becomes a sign of state power, exercised through various mechanisms. Through analysis of state discourse on Syrians in the Turkish media, we find that crisis framing has been deliberately avoided, which we contend is a sign of an implicit “silencing” via media control. This choice of discourse reflects a clear policy to manage public reactions to the mass arrival of refugees.     

Comparisons of tests of distributional assumption in Poisson regression model

Count data consists of discrete non-negative integer values. Poisson regression model is one of the most popular model used to model count data. This model assumes that response variable has Poisson distribution. The purpose of this article is to assess distributional assumption of this model by using some goodness of fit tests. These tests are compared in respect to type I error and power rates of tests with different samples, parameters and sample sizes. Simulation study suggests that the most powerful tests are generally Dean–Lawless and Cameron–Trivedi score tests.     

Additive Nonparametric Regression in the Presence of Endogenous Regressors

In this article we consider nonparametric estimation of a structural equation model under full additivity constraint. We propose estimators for both the conditional mean and gradient which are consistent, asymptotically normal, oracle efficient, and free from the curse of dimensionality. Monte Carlo simulations support the asymptotic developments. We employ a partially linear extension of our model to study the relationship between child care and cognitive outcomes. Some of our (average) results are consistent with the literature (e.g., negative returns to child care when mothers have higher levels of education). However, as our estimators allow for heterogeneity both across and within groups, we are able to contradict many findings in the literature (e.g., we do not find any significant differences in returns between boys and girls or for formal versus informal child care). Supplementary materials for this article are available online.     

Perceptions of diversity and attitudes of tolerance in the ‘fragmented’ U.K.

ABSTRACT

Relying on a quantitative survey (n = 1497) and semi-structured interviews (n = 30) conducted in the U.K., we explore British nationals’, Romanian and Turkish migrants’ attitudes of tolerance and the factors influencing them in the current socio-political context in the U.K. The quantitative data reveal the role of younger age, diverse networks, higher education, attachment to city/region and supranational identifications in more open attitudes towards diversity. The qualitative findings illustrate how diverse these three groups’ attitudes of tolerance can be and how they are affected by their position and status in the U.K. The British’ attitudes show their tolerance can reflect diverse forms of acceptance of ethnic and cultural differences but can also draw lines in terms of civic values opposing ‘those who contribute to society’ versus those who ‘live as parasites’. The Turks are in favour of diversity with the expectation of receiving more civic rights and facing less prejudice. The Romanians tend to have a more ambiguous relation to diversity given their position of stigmatised migrants in the U.K. Our analysis reveal how inclusive or exclusive people’s (sub- and supra-)national identities can be and how these frame their attitudes of tolerance.
