Individual Disaster Assistance For Socially Vulnerable People: Lessons Learned From the Pohang Earthquake in the Republic of Korea

The Republic of Korea has been considered to be relatively safe from earthquake hazards because of the geological location of the Korean Peninsula, which has a low level of intraplate seismic activity. However, an earthquake with a moment magnitude of 5.4 struck the city of Pohang on November 15, 2017, causing 90 casualties and 52 million USD in property losses. During the recovery process after the earthquake, the Korean government provided individual disaster assistance to victims who reported their damages. However, the government disaster assistance could have been unfairly distributed among the socially vulnerable victims who essentially relied on that assistance. This study identifies whether the government disaster assistance was fairly distributed to socially vulnerable victims using a statistical model based on the data from the Pohang earthquake that occurred in 2017 in Korea. A conceptual model was constructed using a structural equation model (SEM) of three factors—social vulnerability, physical vulnerability, and the amount paid out in individual disaster assistance. Furthermore, interviews with and a survey of the victims were conducted to verify the problems identified by the conceptual model. This study found that socially vulnerable victims were less likely to take advantage of the government disaster assistance program.     

Exploratory analysis of verbal aggression in romantic relationships among unmarried men and women: Predictive patterns by gender and race

This is an exploratory study that examined verbal aggression in romantic relationships among unmarried Black and White women and men as a function of gender and race. We employed an ecological approach to examine the receipt of verbal aggression separately for men and women at the levels of individual, relationship, and community. We also explored whether gender-specific correlates of verbal aggression interacted with race. Analyses were based on a sample of 212 women and 133 men in non-marital romantic relationships recruited from 21 U.S. cities for a larger study. Linear mixed-effects models revealed that factors related to experiencing verbal aggression differed substantially for unmarried women and men in romantic relationships. Interesting racial differences also emerged distinctly for women and men.     

From passive assistance to capacity building: assessing the Child Development Fund in Hong Kong

Poverty was not a major issue in Hong Kong before the 1990s. After the Asian financial crisis, the government admitted that poverty was growing and demanded attention. While passive assistance was maintained, increasing emphasis was placed on capacity building to promote self-reliance. The Child Development Fund was introduced to combat intergenerational poverty by developing children's capacity and assets, especially through mentorship. On the basis of published data and interviews with social workers, the project should be considered a success, but it was not without problems. The contribution of social workers to the project was significant but received little government recognition.     

From Caregivers to Caretakers: The Impact of Family Roles on Ethnicity Among Children of Korean and Chinese Immigrant Families

Scholars have long examined the effects of family and community on ethnicity, but they have less to say on why some children may be more receptive to the positive influences of ethnic communities than siblings within the same family. As more immigrants struggle to adapt to the needs and demands of the new global economy, many families are turning to alternative caregiving arrangements that significantly impact the long-term ethnic identities of the second generation. The article considers how adult-age children of immigrants negotiate the emotional disconnects created by these varying contexts of care depending on their individual role within the family and how it shapes their views on ethnicity and culture in their own adult lives. The study focuses in-depth on fourteen semi-structured, in-person interviews with adult-age children of Asian immigrant families in the NY-NJ metropolitan area. Depending on their social status, children of immigrants are integrated into their families: as cultural brokers expected to mediate and care for their family members, as familial dependents who rely on their parents for traditional caregiving functions, or as autonomous caretakers who grow up detached from their parents. I argue that because of their intense engagement with family, cultural brokers describe their ethnic-centered experiences as evoking feelings of reciprocated empathy, whereas on the other end, autonomous caretakers associate their parents’ ancestral culture with ethnocentric exclusion. Depending on how they are able to negotiate the cultural divide, familial dependents generally view their parents’ culture and immigrant experiences through the hierarchical lens of emulation.     

A Snapshot on the Development of Social Work Education in China: A Delphi Study

Social work education in China has now been reinstated for almost two decades, after it was discontinued in the early 1950s. Due to various reasons, so far, there has not been a standardised social work curriculum in China. This article reports on the first empirical study finished in late 2001. Employing a Delphi technique, 47 social work scholars were invited to provide their opinions on the nature of social work in China, the requirements of social work graduates and the social work curriculum at the undergraduate level. The findings indicate that despite the influence of the Western model induced mainly by social work scholars in Hong Kong, social work education in China is moving towards an indigenised model within its unique social–political–cultural context. Respondents tended to adopt an expert model and the ‘helping people to help themselves’ principle. Social work is understood as being instrumental to enhancing the rapid economic changes by employing scientific knowledge and skills to resolve social and personal problems, stabilise society, and enhance social participation. To nurture its graduates with the competence to fulfil these social assignments, a broad‐base of social science knowledge, generic social work skills, special personal qualities and political sensitivity is included in the curriculum.     

New Approaches to Human Mobility: Using Mobile Phones for Demographic Research

This article explores new methods for gathering and analyzing spatially rich demographic data using mobile phones. It describes a pilot study (the Human Mobility Project) in which volunteers around the world were successfully recruited to share GPS and cellular tower information on their trajectories and respond to dynamic, location-based surveys using an open-source Android application. The pilot study illustrates the great potential of mobile phone methodology for moving spatial measures beyond residential census units and investigating a range of important social phenomena, including the heterogeneity of activity spaces, the dynamic nature of spatial segregation, and the contextual dependence of subjective well-being.     

Combined Pricing and Portfolio Option Procurement

In this paper, we study a single‐product periodic‐review inventory system that faces random and price‐dependent demand. The firm can purchase the product either from option contracts or from the spot market. Different option contracts are offered by a set of suppliers with a two‐part fee structure: a unit reservation cost and a unit exercising cost. The spot market price is random and its realization may affect the subsequent option contract prices. The firm decides the reservation quantity from each supplier and the product selling price at the beginning of each period and the number of options to exercise (inventory replenishment) at the end of the period to maximize the total expected profit over its planning horizon. We show that the optimal inventory replenishment policy is order‐up‐to type with a sequence of decreasing thresholds. We also investigate the optimal option‐reservation policy and the optimal pricing strategy. The optimal reservation quantities and selling price are shown to be both decreasing in the starting inventory level when demand function is additive. Building upon the analytical results, we conduct a numerical study to unveil additional managerial insights. Among other things, we quantify the values of the option contracts and dynamic pricing to the firm and show that they are more significant when the market demand becomes more volatile.     

Opportunistic data structures for range queries

In this paper, we study the problem of supporting range sum queries on a compressed sequence of values. For a sequence of n k-bit integers, k ≤ O(log n), our data structures require asymptotically the same amount of storage as the compressed sequence if compressed using the Lempel-Ziv algorithm. The basic structure supports range sum queries in O(log n) time. With an increase by a constant factor in the storage complexity, the query time can be improved to O(log log n + k). The work described in this paper is fully supported by a grant from the Research Grant Council of the Hong Kong Special Administrative Region, China (CityU 1071/02E). A preliminary version has appeared in 11th International Conference in Computing and Combinatorics (COCOON'05).
