The effects of child maltreatment on childhood behaviour problems in South Korea: findings from the fifth Korea Child and Youth Panel Survey (the 2014 KCYPS)

The study examines the effects of child maltreatment on children behavioural problems in South Korea. We found that 11.5% of children experienced physical abuse, 28.7% experienced emotional abuse and about 35% experienced neglect. After controlling for all socio-demographic factors, children who experienced physical abuse, emotional abuse and neglect were more likely to develop internalised as well as externalised behavioural problems such as depression, aggression, underage smoking, underage drinking and engaging in cyber delinquency. The results point towards a need to develop social welfare interventions to mitigate physical/emotional abuse and neglect so as to prevent behavioural problems in South Korean children.     

A Note on the Fisher Information in Exponential Distribution

ABSTRACT

It is known that the Fisher information in any set of order statistics can be simplified to a sum of double integrals. In this article, we show that it can be further simplified to a sum of single integrals for the scale parameter of an exponential distribution. Moreover, we use the result and provide a simple method of obtaining the optimal spacing of order statistics.     

Informal social networks in Korea: Covering the cost of major life events

This article investigates an informal voluntary social arrangement for financial assistance with discrete major life events known in Korea as Sang-Ho-Bu-Jo. This informal voluntary arrangement is neither public nor private, but is based on social networks that produce a unique form of civic society. Sang-Ho-Bu-Jo covers people's transitional one-time needs. This study explores the practice of Sang-Ho-Bu-Jo and its origins and provides the first systematic empirical study of this social phenomenon. Three large databases are used to analyze the scope and level of participation, as well as what variables correlate with such involvement. The study finds a high rate of participation, over 80% of households, and an average investment of 2–4% of household expenditure. Sang-Ho-Bu-Jo can help scholars and policy makers worldwide in understanding the role of socialization, social networks, and social capital in explaining innovative informal methods of social care.     

Logrank test for bivariate survival data

The logrank test procedure for testing bivariate symmetry against asymmetry in matched-pair data is proposed. The presented test statistic is based on Mantel-Haenszel type statistics evaluated at diagonal grid points on the plane obtained from distinct uncensored failure times. The asymptotic results of the proposed test are derived and an example is shown to illustrate the methodology.     

Responding to child maltreatment: Comparison between the USA and China

A recent study estimated that over one‐fourth of Chinese children have suffered maltreatment (Fang et al., 2015 ). However, the current child welfare policy in China is limited to orphans, abandoned children, and children with disabilities. Also, there is very little comparative research in China on Chinese and other countries’ child welfare systems. The purpose of this study was to analyze applicable US and Chinese child welfare policies, identify gaps in Chinese policy regarding child maltreatment, and make recommendations for a policy agenda for improving child welfare in China based on cultural values and existing policy structures. Results show that China has considerable capacity to make improvements in child protective services, foster care, and adoption policies. Based on the results of this study, several implications are provided to develop China's child maltreatment policy to increase children's outcomes of well‐being, safety, and permanency. Key Practitioner Message: ? To understand the background and system of current Chinese child maltreatment policy; ? To review US child maltreatment policy and its implementation to identify gaps in the Chinese child maltreatment system; ? To provide policy suggestions to develop Chinese child maltreatment policy and provide recommendations for social work education and practice in China.     

Do training programs work? An assessment of pharmacists activities in the field of chemical dependency

OBJECTIVES: The primary objective of this study was to determine if a selected sample of pharmacists who had attended a chemical dependency training program were performing more chemical dependency related activities than a group of American Pharmaceutical Association (APhA) members who had not had this training. Additionally, an assessment of the perceived barriers to performing chemical dependencyrelated activities was performed. DESIGN: A confidential mail questionnaire was sent to 305 Utah School participants and 305 APhA members who had not participated in the program (See Appendix). RESULTS: Respondents who had received educational training in chemical dependency were more likely to perform the following activities: lecture to community groups and health care professionals about chemical dependency, participate in a pharmacists' recovery program, provide patients with information about treatment centers, and counsel patients about the alcohol in over-the-counter products. Respondents who had not received chemical dependency training indicated that the following barriers prevented them from taking a more active role in the chemical dependency field: lack of knowledge of chemical dependency resources in the community, unaware of how to get involved with the state recovery program, belief that involvement in the state recovery program would hurt their professional reputation, belief that chemically dependent individuals cannot be rehabilitated, and uncomfortable working with chemically dependent patients. CONCLUSIONS: Pharmacists who have attended substance abuse training programs are performing more chemical dependency activities than pharmacists who have not received training in chemical dependency. In addition, different barriers to performing chemical dependency related activities exist between pharmacists with and without training in this field.

Young Adults’ Life Outcomes and Well-Being: Perceived Financial Socialization from Parents,the Romantic Partner,and Young Adults’ Own Financial Behaviors

We examined how perceived financial socialization—from parents, the romantic partner, and young adults’ own behavior—was associated with young adults’ life outcomes and well-being (i.e., physical and mental health, finances, romantic relationship). Using data (N?=?504) from young adults specific to their finances, results from hierarchical regression analyses showed that young adults’ own financial behaviors were the most patterned, followed by financial socialization from the romantic partner, and then from financial socialization from parents (only objective financial knowledge). We discuss how young adults’ financial behavior, financial socialization from the romantic partner and, to a lesser extent, parental socialization are associated with young adults’ life domains, underscoring the developmental salience of increased financial capability and relationship formation and decreased dependence on parents during the transition to adulthood.     

Lambda number for the direct product of some family of graphs

An L(2, 1)-labeling for a graph \(G=(V,E)\) is a function f on V such that \(|f(u)-f(v)|\ge 2\) if u and v are adjacent and f(u) and f(v) are distinct if u and v are vertices of distance two. The L(2, 1)-labeling number, or the lambda number \(\lambda (G)\), for G is the minimum span over all L(2, 1)-labelings of G. When \(P_{m}\times C_{n}\) is the direct product of a path \(P_m\) and a cycle \(C_n\), Jha et al. (Discret Appl Math 145:317–325, 2005) computed the lambda number of \(P_{m}\times C_{n}\) for \(n\ge 3\) and \(m=4,5\). They also showed that when \(m\ge 6\) and \(n\ge 7\), \(\lambda (P_{m}\times C_{n})=6\) if and only if n is the multiple of 7 and conjectured that it is 7 if otherwise. They also showed that \(\lambda (C_{7i}\times C_{7j})=6\) for some i, j. In this paper, we show that when \(m\ge 6\) and \(n\ge 3\), \(\lambda (P_m\times C_n)=7\) if and only if n is not a multiple of 7. Consequently the conjecture is proved. Here we also provide the conditions on m and n such that \(\lambda (C_m\times C_n)\le 7\).     

The added value of virtual reality technology and force feedback for surgical training simulators

Laparoscopic surgery requires more specialized training of the surgeons than traditional open surgery. The Virtual Basic Laparoscopic Surgical Trainer (VBLaST) is being developed as a virtual version of the Fundamentals of Laparoscopic Skills (FLS) trainer. This study assessed the current haptic and virtual reality (VR) technology of a virtual peg transfer task of the VBLaST, based on the subjective preference of surgeons and their objective task performance measures. Twenty-one surgical residents, fellows and attendings performed a peg-transfer task in the FLS and the VBLaST. Each subject performed 10 trials on each simulator. Results showed that subjects performed significantly better on the FLS than on the VBLaST. Subjects showed a significant learning effect on both simulators, but with an accelerated improvement on the VBLaST. Even so, 81% of the subjects preferred the FLS over the VBLaST for surgical training which could be attributed to the novelty of the VR technology and existing deficiencies of the haptic interface. Despite the subjective preference for the physical simulator, the performance results indicate an added value of VR and haptics in surgical training, which is expected to be demonstrated in more surgically relevant tasks such as suturing and knot-tying.
