The unequal impact of Covid-19 on the lives and rights of the children of modern slavery survivors,children in exploitation and children at risk of entering exploitation

This article discusses the unequal impact of Covid-19 on the lives of the children of survivors of modern slavery, child victims of exploitation and children at risk of exploitation in the UK. It draws on research that has analysed the risks and impacts of Covid-19 on victims and survivors of modern slavery. It explores how pandemic responses may have hindered these children's rights to education, food, safety, development and participation and representation in legal processes. It suggests that the pandemic should be used as an impetus to address inequalities that existed pre-Covid-19 and those that have been exacerbated by it.     

Rethinking the Canon: Reflections on a Text That Ought to be Essential Reading

Abstract

The 2006 war in Lebanon that erupted between Hezbollah and Israel marked the largest evacuation of Americans abroad since World War II. This article captures the experiences of Lebanese-American women and investigates how gender identity was expressed during these evacuations. Presented from the point of view of a participant-observer and personal interviews, findings show that gender became a master identity that influenced these women's choices regarding how to escape the country and return to the United States. Some embraced dependency upon masculinist exercises of power while others claimed agency as they determined their own fate and carried out their own evacuation without waiting to be rescued by the state or male kin members. The evacuation stories in this article confirm and illuminate the complexity of ethnic citizenship and gendered agency.     

Seasonal and weather-related behavioral effects among urban Aboriginal, urban non-Aboriginal, and remote Aboriginal participants in Canada

The influence of seasonal change and weather on mood, social activity, weight, food consumption, and sleep length was compared across urban Aboriginals (n = 43), urban non-Aboriginals (n = 49), and remote Aboriginals (n = 39) in Ontario, Canada. Such research is important since climate change may differentially shape the well-being of social groups. Behavioral items—including mood, social activity, weight, sleep, and food consumption—were measured using the Seasonal Pattern Assessment Questionnaire, and associations between these items and meteorological data were examined with bivariate and multivariate approaches. Weather variables had consistent, significant associations with behavior except within the remote Aboriginal group despite living in a more extreme climate. Lifestyle and adaptation may contribute to an increased weather tolerance among remote Aboriginal people, intriguing findings as cultures grapple with the implications of future climate change.     

The L(2,1)-labelling problem for cubic Cayley graphs on dihedral groups

A k-L(2,1)-labelling of a graph G is a mapping f:V(G)→{0,1,2,…,k} such that |f(u)?f(v)|≥2 if uv∈E(G) and f(u)≠f(v) if u,v are distance two apart. The smallest positive integer k such that G admits a k-L(2,1)-labelling is called the λ-number of G. In this paper we study this quantity for cubic Cayley graphs (other than the prism graphs) on dihedral groups, which are called brick product graphs or honeycomb toroidal graphs. We prove that the λ-number of such a graph is between 5 and 7, and moreover we give a characterisation of such graphs with λ-number 5.     

A spatial Bayesian semiparametric mixture model for positive definite matrices with applications in diffusion tensor imaging

Studies on diffusion tensor imaging (DTI) quantify the diffusion of water molecules in a brain voxel using an estimated 3 × 3 symmetric positive definite (p.d.) diffusion tensor matrix. Due to the challenges associated with modelling matrix‐variate responses, the voxel‐level DTI data are usually summarized by univariate quantities, such as fractional anisotropy. This approach leads to evident loss of information. Furthermore, DTI analyses often ignore the spatial association among neighbouring voxels, leading to imprecise estimates. Although the spatial modelling literature is rich, modelling spatially dependent p.d. matrices is challenging. To mitigate these issues, we propose a matrix‐variate Bayesian semiparametric mixture model, where the p.d. matrices are distributed as a mixture of inverse Wishart distributions, with the spatial dependence captured by a Markov model for the mixture component labels. Related Bayesian computing is facilitated by conjugacy results and use of the double Metropolis–Hastings algorithm. Our simulation study shows that the proposed method is more powerful than competing non‐spatial methods. We also apply our method to investigate the effect of cocaine use on brain microstructure. By extending spatial statistics to matrix‐variate data, we contribute to providing a novel and computationally tractable inferential tool for DTI analysis.     

Representing Children of Prisoners in the Public Domain: Comparing Children’s Views and Policy Documents

ABSTRACT

Australian adult prisoner numbers continue to rise to what have been described as unprecedented and unsustainable levels. Research highlights that there are wide-ranging consequences of incarceration for families, and particularly for children. Despite the available research describing the negative impact of parental incarceration on children, it has been argued that these children remain virtually invisible to policy makers and social programs. Using a combination of policy analyses and findings from a research project undertaken in the Australian Capital Territory aimed at identifying the needs of children who have a parent in prison, we examine how this group of children is constructed and responded to by the systems that surround the children. It is argued that it is only when children are seen in a more holistic way that systems can respond more collaboratively to effectively support children.

IMPLICATIONS

• Children of prisoners have needed to rely on adults to recognise the problem of parental incarceration and petition for them.

• It is time for those who inform and develop social policy to consider the impact of current policies on children.

• It is only when children are seen in a more holistic way that systems can respond more collaboratively to effectively support them.

     

NONLINEAR TUBE-FITTING FOR THE ANALYSIS OF ANATOMICAL AND FUNCTIONAL STRUCTURES

We are concerned with the estimation of the exterior surface and interior summaries of tube-shaped anatomical structures. This interest is motivated by two distinct scientific goals, one dealing with the distribution of HIV microbicide in the colon and the other with measuring degradation in white-matter tracts in the brain. Our problem is posed as the estimation of the support of a distribution in three dimensions from a sample from that distribution, possibly measured with error. We propose a novel tube-fitting algorithm to construct such estimators. Further, we conduct a simulation study to aid in the choice of a key parameter of the algorithm, and we test our algorithm with validation study tailored to the motivating data sets. Finally, we apply the tube-fitting algorithm to a colon image produced by single photon emission computed tomography (SPECT) and to a white-matter tract image produced using diffusion tensor imaging (DTI).     

Complementarity of pensions and training under multiemployer plans

We compare firmoptimizing and institutional models of labor contracts to investigate how different types of pension plans affect employee training. Unlike previous stud-ies, we consider an expanded voice model of training and pension coverage in which worker and union preferences feed back on firm decisions, and we test for this bidi-rectional causality between pensions and training. A standard view is that firms pro-vide pensions to optimize their training costs. However, when pension coverage is treated as endogenous in a twostage least squares regression (the data are merged 1991 CPS samples), pensions have a negative effect on training. In contrast, when the pension is a definedbenefit, multiemployer plan, training and pensions are comple-ments, consistent with both optimizing and institutional models. We are grateful for excellent research assistance from Michael Ash, Bhashkar Mazumder, and Judith Ruha and for suggestions from Dale Belman, David Card, B.J. Lee, David MacPherson, and John Turner.     

Reclaiming SPSSI's Radical Promise: A Critical Look at JSI's "Impact of Welfare Reform" Issue

Studies of the impact of welfare reform reported in the Winter 2000 issue of JSI uniformly conclude that the results are mixed. Uncritically accepting the "official story" that success can be evaluated by the numbers of former welfare recipients who are working, the researchers, adopting a neutral "objective" perspective, focus on "barriers" to achieving this goal. We argue that this "honest broker" model, in which researchers provide "scientific" data to those in power, neglects the roles of social psychologists as social critics and political activists that were among the diverse perspectives among SPSSI's founders. We call for a rebirth of these more radical orientations and offer examples of research approaches that involve entering into alliances with oppressed groups in society. We hope our critique will stimulate wider discussion about SPSSI's future mission.     

Exploring the Causal Story: Gender, Active Representation, and Bureaucratic Priorities

Using the theoretical framework posited by Keiser et al. (2002),researchers have found active representation for gender in severalpublic organizations (Keiser et al. 2002; Nicholson-Crotty andMeier 2002; Wilkins and Keiser 2006). This article uses individual-leveldata to explore the causal story behind previous aggregate levelfindings that suggest that female child support enforcementsupervisors provide active representation to female clients,who directly benefit from increased child support collections(Wilkins and Keiser 2006). This article tests whether femalechild support enforcement supervisors behave differently thantheir male counterparts. The findings suggest that female supervisorshave different priorities and/or spend their time differentlythan their male counterparts, and these differences may leadto active representation. Using survey data, I examine the individual-levelcausal story behind the relationship between individuals andbureaucratic priorities.
