The Development of Anticipatory Smiling

When do infants begin to communicate positive affect about physical objects to their social partners? We examined developmental changes in the timing of smiles during episodes of initiating joint attention that involved an infant gazing between an object and a social partner. Twenty‐six typically developing infants were observed at 8, 10, and 12 months during the Early Social‐Communication Scales, a semistructured assessment for eliciting initiating joint attention and related behaviors. The proportion of infant smiling during initiating joint attention episodes did not change with age, but there was a change in the timing of the smiles. The likelihood of infants smiling at an object and then gazing at the experimenter while smiling (anticipatory smiling) increased between 8 and 10 months and remained stable between 10 and 12 months. The increase in the number of infants who smiled at an object and then made eye contact suggests a developing ability to communicate positive affect about an object.     

A Route to Safety: Using Bus Boarding Data to Identify Roles for Transport Providers within Contextual Safeguarding Systems

During adolescence, risk to young people's safety shifts from familial to community contexts. Contextual safeguarding has emerged in response to this dynamic; by providing a conceptual framework through which to incorporate extra‐familial contexts (and those who manage them) into traditionally family focused child protection systems. This paper uses Geographic Information System mapping techniques to explore the extent to which bus boarding data could be used to: target protective interventions in public spaces; evidence routes where young people may be vulnerable; and build local area problem profiles. In doing so it provides foundational evidence for including transport providers in contextual safeguarding systems.     

Contextualizing case reviews: A methodology for developing systemic safeguarding practices

This paper introduces a systemic methodology for reviewing professional responses to abuse between young people. The approach, “contextual case reviewing,” draws upon constructivist structuralism to assess the extent to which safeguarding practices engage with the social and public contexts of abuse. The paper conceptually compares the methodologies of contextual case review and other serious case review methods before drawing upon findings from 2 studies, which used the contextual case review methodology to explore the extrafamilial nature of peer‐on‐peer abuse and the ability of child protection practices to engage with this dynamic. Thematic findings from these studies regarding the practical interpretation of “significant harm” and “capacity to safeguard,” as well as their use within child protection assessments, are used to challenge conclusions of other case reviews, which imply that child protection procedures are sufficient for safeguarding young people. Contextual case reviews suggest that safeguarding practices, and the legislation that underpins them, are culturally, procedurally, and organisationally wedded to the context of the home, whereas insufficiently engaged with extrafamilial contexts of significant harm. The application of these issues require interrogation if social work systems are to provide sufficient mechanisms for safeguarding young people and families at risk of significant harm.     

Social issues in contemporary native America: reflections from Turtle Island

The purpose of this study was to explore how the death and dying-related beliefs of caregivers influence their actual caregiving behavior, and to explore factors that may prevent them from translating these beliefs into functional behavior. Using a biopsychosocial-spiritual- environmental framework, semi-structured in-depth interviews were conducted with three primary caregivers of patients diagnosed with terminal illness. Caregiving behavior was found to be associated with the biopsychosocial-spiritual-environmental beliefs of the caregivers. These beliefs could have been influenced by the caregivers' past experiences with death and dying. Financial difficulty might also be a main obstacle hindering caregivers from providing the kind of care they believed was best for the patients.     

REDUCING PUBLIC‐PRIVATE SECTOR PAY DIFFERENTIALS: THE SINGLE SPINE PAY POLICY AS A NATURAL EXPERIMENT IN GHANA

Empirical studies have documented the existence of the public‐private pay differentials in both developed and developing countries. The implementation of policies aiming to reduce this gap has however been mitigated or inconclusive. This paper exploits the Single Spine Pay Policy (SSPP) in Ghana as a natural experiment to examine the effectiveness of wage policies in developing countries. The SSPP was implemented in 2010 by the Government of Ghana to address the public‐private sector wage gap and improve productivity in the public sector. Using a quantile treatment effect approach based on a difference‐in‐difference estimation, we show that the SSPP has yet to reduce the wage gap between the public and private sectors across the entire distribution of earnings in Ghana. The improvement observed is only at the lower tail of the distribution of earnings. However, the SSPP has a larger effect on the earnings of female workers than that of males in the education and health services sectors while male workers have benefited more in the administration sector, suggesting that the policy was successful in reducing the gender wage gap in the education and health services sectors but has widened this gap in the administration sector. Moreover, the SSPP has decreased the productivity of workers across the distribution of earnings, mainly due to a decrease in the effort of female public sector workers in the education and health sectors and male workers in the administration sector.

Instrument endogeneity and identification-robust tests: Some analytical results

When some explanatory variables in a regression are correlated with the disturbance term, instrumental variable methods are typically employed to make reliable inferences. Furthermore, to avoid difficulties associated with weak instruments, identification-robust methods are often proposed. However, it is hard to assess whether an instrumental variable is valid in practice because instrument validity is based on the questionable assumption that some of them are exogenous. In this paper, we focus on structural models and analyze the effects of instrument endogeneity on two identification-robust procedures, the Anderson–Rubin (1949, AR) and the Kleibergen (2002, K) tests, with or without weak instruments. Two main setups are considered: (1) the level of “instrument” endogeneity is fixed (does not depend on the sample size) and (2) the instruments are locally exogenous, i.e. the parameter which controls instrument endogeneity approaches zero as the sample size increases. In the first setup, we show that both test procedures are in general consistent against the presence of invalid instruments (hence asymptotically invalid for the hypothesis of interest), whether the instruments are “strong” or “weak”. We also describe cases where test consistency may not hold, but the asymptotic distribution is modified in a way that would lead to size distortions in large samples. These include, in particular, cases where the 2SLS estimator remains consistent, but the AR and K tests are asymptotically invalid. In the second setup, we find (non-degenerate) asymptotic non-central chi-square distributions in all cases, and describe cases where the non-centrality parameter is zero and the asymptotic distribution remains the same as in the case of valid instruments (despite the presence of invalid instruments). Overall, our results underscore the importance of checking for the presence of possibly invalid instruments when applying “identification-robust” tests.     

Near exogeneity,weak identification and specification testing: Some asymptotic results

The paper studies the asymptotic size property of various specification tests in linear structural models where instrumental variables may locally violate the exclusion restrictions. Our results provide some new insights and extensions of earlier studies. In particular, we derive an explicit formula of the asymptotic size of the tests which shows clearly the factors that influence their size under instrument endogeneity. We show that all tests have correct asymptotic size when the usual orthogonality condition holds, but their asymptotic size can be arbitrary large even if only one instrument is slightly correlated with the error term. We present a Monte Carlo experiment that confirms our theoretical findings.     

Peer Support Groups for Child Welfare–Involved Families

Studies on risk factors and circumstances related to child maltreatment have continuously emphasized the important role of social support. As a result, peer support groups have been gaining attention and recognition in recent years in the field of child maltreatment prevention. However, little is known about the benefits that child welfare–involved parents receive in peer support groups, as well as the distinctive service elements that make these groups successful. By examining child welfare–involved parents’ experiences participating in peer support groups, this study provided a better understanding of the perceived beneficial aspects of peer support groups, specific types of supports offered to and by peers, and unique characteristics of these groups.
