Effects of Parents' Migration on the Education of Children Left Behind in Rural China

This essay draws on an original cross‐sectional survey of 1,010 children and their guardians in highly migratory regions of Anhui and Jiangxi provinces located in China's interior. It uses propensity score matching, a technique that mitigates endogenity, to examine the impact of parental migration and post‐migration guardianship arrangements on the children's educational performance as measured by test scores for Chinese and mathematics. One core finding is that the educational performance of children is adversely affected by parental migration only when both parents migrate or when a non‐parent guardian is the principal carer. Additionally, longer durations of parental absence are associated with poorer educational performance. The migration of two parents only significantly adversely affects the educational performance of boys. There is no significant effect on the educational performance of girls. On the basis of our findings we argue that rather than support left‐behind children within the countryside, the long‐term policy response should be to remove the institutional obstacles that prevent family resettlement in the cities.     

The Gambler’s Fallacy and the Hot Hand: Empirical Data from Casinos

Research on decision making under uncertainty demonstrates that intuitive ideas of randomness depart systematically from the laws of chance. Two such departures involving random sequences of events have been documented in the laboratory, the gambler’s fallacy and the hot hand. This study presents results from the field, using videotapes of patrons gambling in a casino, to examine the existence and extent of these biases in naturalistic settings. We find small but significant biases in our population, consistent with those observed in the lab.JEL Classification: C9 Experimental, C93 Field Experiments, D81 Decision Making under Risk and Uncertainty     

Victoria Climbie Inquiry Data Corpus Project: Using the Delphi Method in Multidisciplinary Child Protection Research

This paper introduces the Delphi research method and analysesits usefulness in multi-agency research. In particular, theauthors examine how it was used in a project aimed at makingthe material generated by the Victoria Climbié Inquiryaccessible to child welfare/protection professionals throughorganizing the oral evidence in such a way that it can becomea web-based data corpus. The thematic analysis of research data-setsusually only reflects the theoretical and analytical ideas ofthe researchers; however, our research demonstrates that usingthe Delphi method incorporates thematic ideas both from researchersand from active professionals, thereby pooling expertise. Thuswe argue that the Delphi method represents a valuable tool inmultidisciplinary child welfare research as it embeds a breadthof expertise throughout the research process.     

Impact of Journal Cancellations on Interlibrary Loan Demand

Rachel Fleming and Kristin Calvert of Western Carolina University discuss their study of interlibrary loan borrowing requests in the three years surrounding a journal cancellation project. Noting that the impact of such a cancellation on interlibrary loan has not been studied since the 1990s, they examine numerous facets of requests for cancelled and non-cancelled journals, including request per journal, year of article requested, and request history for newly cancelled journals. Though journal cancellations resulted in a 2 percent increase in interlibrary loan requests, this number proved so small that Calvert and Fleming judged that their cancellations caused no undue effects.     

Out of mind,out of sight? Leading distributed workers to ensure health and safety

ABSTRACT

Current frameworks of leadership are based on face-to-face interaction. A growing number of workers work away from their main location of work; this makes it challenging for leaders to ensure the health and safety of distributed workers. In the present study, we explore the relationship between line managers’ health and safety leadership and distributed workers’ health and safety behaviours. We also explore the organisational procedures and practices that may enhance the impact of health and safety leadership. We included a broad range of distributed workers (in analyses, minimum N?=?626) from 11 organisations. We found that health-and-safety-specific leadership was positively related to distributed workers’ self-rated health, safety compliance and safety proactivity. These relationships were augmented by distributed workers’ sense of being included in the workplace. Knowledge sharing among colleagues was associated with safety compliance when health-and-safety-specific leadership was low. Our results indicate that one way of addressing the challenges of distributed working may be through line managers putting health and safety on the agenda.     

The Unintended Consequences of “Lack of Supervision” Child Neglect Laws: How Developmental Science Can Inform Policies about Childhood Independence and Child Protection

Policies and programs designed to serve children and families are sometimes misaligned with developmental science research. Broad child neglect reporting laws, first adopted by the United States in 1974, have led to families being prosecuted by child protection authorities for allowing children to participate in everyday age-appropriate activities unsupervised. In this report we describe the challenges of defining child neglect and outline the current landscape of neglect laws in the United States. We then provide a broad overview of some of the developmental milestones children need to reach to participate in unsupervised activities and the benefits of independent activities on child development. Children can often accomplish tasks at a much younger age than law, parents, and caregivers in the U.S. believe. We then turn to the literature from across the world and argue that culture, not innate ability, drives much of the variation in the age at which children can do things on their own. Finally, we make recommendations to parents, caregivers, legislators, advocates, and developmental scientists to better align practice with research. This is a social justice issue that should resonate across party, racial, and class lines. Developmental scientists are needed as advocates and advisors on policies impacting children and families, especially child neglect laws.     

Seasonal activity patterns of sympatric eastern gray squirrels (Sciurus carolinensis) and fox squirrels (Sciurus niger) in a Midwestern metropolitan region

Niche partitioning reduces interspecific competition, facilitating coexistence. In urban ecosystems, however, habitat loss reduces species’ ability to spatially partition activity. Temporal partitioning may thus increase in urban areas as species, unable to avoid each other spatially, partition time to avoid competition. In Midwestern US cities, eastern gray squirrels (Sciurus carolinensis) and fox squirrels (S. niger) co-occur and compete for resources. We identified urban gray and fox squirrel activity patterns and how they vary with season, land cover, and among sites where they do and do not co-occur using camera-trap data. Both species’ activity patterns varied with season and canopy and impervious surface cover. Gray squirrel activity patterns varied in the presence of fox squirrels only in the fall, providing limited support for our temporal partitioning hypothesis. Temporal niche partitioning may thus play a role in supporting these species co-existence when competition is seasonally-elevated (e.g., fall hording), but appears less important in other seasons.

     

Order Stability in Supply Chains: Coordination Risk and the Role of Coordination Stock

The bullwhip effect describes the tendency for the variance of orders in supply chains to increase as one moves upstream from consumer demand. We report on a set of laboratory experiments with a serial supply chain that tests behavioral causes of this phenomenon, in particular the possible influence of coordination risk. Coordination risk exists when individuals' decisions contribute to a collective outcome and the decision rules followed by each individual are not known with certainty, for example, where managers cannot be sure how their supply chain partners will behave. We conjecture that the existence of coordination risk may contribute to bullwhip behavior. We test this conjecture by controlling for environmental factors that lead to coordination risk and find these controls lead to a significant reduction in order oscillations and amplification. Next, we investigate a managerial intervention to reduce the bullwhip effect, inspired by our conjecture that coordination risk contributes to bullwhip behavior. Although the intervention, holding additional on‐hand inventory, does not change the existence of coordination risk, it reduces order oscillation and amplification by providing a buffer against the endogenous risk of coordination failure. We conclude that the magnitude of the bullwhip can be mitigated, but that its behavioral causes appear robust.
