Do Survey Spot-Check and Threat Improve Data Quality? Evidence from a Field Experiment

In this study, we examine the effect of interview observation on data quality of a large-scale individual survey in Vietnam. External spot-check teams were sent to randomly selected enumeration areas to attend and observe survey training courses and field interviews of interviewers. We find that interviewers have a lower number of item non-responses in collected data when being observed by the spot-check teams. The effect of a spot-check of field interviews appears to be higher than the effect of a spot-check of training courses. However, we do not find a significant effect of a spot-check threat: informing interviewers of a possible spot-check without actually visiting does not reduce item non-responses.     

The Relationship Between Use of Specific Services,Parental Problems,and Reunification With Children Placed in Foster Care

Research studies have found that for parents with children in foster care, use of problem-targeted services increases the likelihood of reunification. However, available research focuses almost entirely on substance abusing mothers, and rarely considers parents' use of parenting classes and counseling, services that are commonly ordered for most reunifying parents. This study examined the effects of parents' use of specific services on reunification. Findings suggest that in addition to parents' use of problem-targeted services, use or compliance with parenting classes and counseling services is also heavily weighted in reunification decision-making. Further research is needed to identify factors associated with service use and advance our understanding of the effectiveness of reunification services.     

Can Labelling Policies Do More Harm Than Good? An Analysis Applied to Environmental Labelling Schemes

In certain plausible circumstances, the introduction of labelling schemes can lead to adverse effects. In the case of ecolabelling, the adverse effects are an environmental degradation rather than an environmental improvement. To take into account the environmental sensitiveness or responsiveness of consumers, we introduce the concept of environmental elasticity which enables us to classify goods. In a basic analytical model, we describe the conditions under which different outcomes—overall impacts of change in environmental quality due to environmental labelling—arise after the introduction of an ecolabelling scheme. We show that an ecolabelling scheme can lead to an increase in purchases of environmentally sustainable products. The net effect on the environment can be worse than the initial situation without ecolabelling, because the environmental unit improvement is compensated by an over-consumption. We suggest several tests to detect this potential perverse effect, some policy implications to avoid it and stress the need for further research.JEL Classification: D11, L15, Q28     

The Infant Injury Database: A Tool for the Study of Injury Patterns in Medicolegal Investigations of Child Abuse

In 2012, the Harris County Institute of Forensic Sciences began prospectively collecting injury data from pediatric autopsies. These data and associated case information from 635 pediatric cases are archived in the Infant Injury Database (IID). This paper introduces the IID to the forensic community and demonstrates its potential utility for child abuse and infant fatality investigations. The database is intended to be a source of evidence‐based research for coroners/medical examiners and clinicians in the recognition and diagnosis of child abuse. RR estimates were employed to quantify the relationship between individual autopsy findings to trauma‐related and nontrauma‐related causes of death. For example, unsurprisingly, the RR of trauma cases with multiple injury types is significantly greater than other causes of death, but the RR results provide a quantitative representation of the relationship. ROC curve modeling of the presence/absence of various injury types performed well at discriminating trauma from other causes of death (AUC = 0.96).     

借助汉越音、汉越词对越汉语词汇教学

一、越语与汉语的关系(一)越语与汉语的关系首先要说明越语和汉语是不同语系的两种语言,所以,我们在对越南学生进行汉语教学时不能采用同源教学法。关于越语的语源,最近越南境外的学者都普遍认为越语属于南亚语系(王力先生也接受这种观点),即与芒语(M uong)是同一个语言系统,是     

When Faced with Income and Asset Shocks,Do Poor Rural Households in Vietnam Smooth Food Consumption or Assets?

Vietnamese rural households are exposed to severe covariate and idiosyncratic shocks. However, these households are remarkably resilient and have steadily increased real income and consumption over the survey period 2006 to 2012. To explain household strategies to cope with shocks we test three theoretical models: the Permanent Income Hypothesis (PIH), Complete Market Hypothesis (CMH), and Asset Smoothing Theory (AST). There is support for AST as households smooth productive assets rather than consumption; and for CMH as households smooth consumption against idiosyncratic, but not covariate shocks. There is no support for PIH.     

Ethnic minority development in Vietnam

This study examines the disparities in living standards between and among the different ethnic groups in Vietnam. Using data from the Vietnam Living Standards Surveys and 1999 Census, we show that ‘majority’ Kinh and Hoa households have substantially higher living standards than ‘minority’ households from Vietnam's 52 other ethnic groups. While the Kinh, Hoa, Khmer and Northern Highland Minorities benefited from economic growth in the 1990s, the position of the Central Highland Minorities stagnated. Decompositions show that even if minority households had the same endowments as Kinh households, this would close no more than a third of the gap in their per capita expenditures. While some ethnic minorities seem to be doing well out of a strategy of assimilating with the Kinh-Hoa majority, others groups are attempting to integrate economically while retaining distinct cultural identities, and a third group is largely being left behind by the growth process.     

When development means political maturation: adolescents as miniature communists in post-war and pre-reform Vietnam, 1975–1986

In this study, I documented the conceptualization and representation of adolescence in Vietnam between the end of the Vietnam War and before Vietnam adopted the Western market economy. Using historical archives, especially newspapers written for and by adolescents, I argued that during this period, the Vietnamese society conceptualized life course development as a process through which an individual gains political maturity, which means the learning and practicing of communist doctrines. As such, adolescence was viewed between 1975 and 1986 as a political stage that prepares youths to become mature communists. Adolescents, therefore, were portrayed as miniature communists with norms, attitudes and behaviors shaped by communist doctrines. Adolescence was not associated with problem behavior or sexual maturation.     

Does mobility matter? The neighborhood conditions of housing voucher holders by race and ethnicity

Abstract

Mobility is one mechanism used to address the federal goals of deconcen‐trating poverty and minorities. The Housing Choice Voucher Program relies on participants to make residential location decisions consistent with these goals. Our research investigates the level and impact of mobility on the neighborhood quality of voucher holders, their neighborhood conditions by race and ethnicity, and perceived obstacles to mobility within the jurisdiction of a Southern California housing authority.

About one‐third of the sample moved during the study, and moving resulted in improved neighborhoods for only one subset of movers. Minorities live in more impoverished, overcrowded neighborhoods than nonminorities, even when controlling for mobility status, contract rent, and other factors. Further, most voucher holders see the lack of rental units as a major obstacle to mobility. These findings suggest that current policy is not uniformly achieving deconcentration and that real and perceived barriers to mobility exist, especially for minorities.
