What Affects the Happiness of Adopted Children in South Korea? Does the Adoption Matter to Their Happiness?

Static Numbers to Dynamic Statistics: Designing a Policy-Friendly Social Policy Indicator Framework

In line with the economic crisis and rapid socio-demographic changes, the interest in ??social?? and ??well-being?? indicators has been revived. Social indicator movements of the 1960s resulted in the establishment of social indicator statistical frameworks; that legacy has remained intact in many national governments and international organisations. With this background, this research examines whether existing social indicator frameworks are valid and effective enough to address increasingly complex social issues. The authors argue that, despite some improvements, current social indicators fail to provide an effective framework and tool for measuring the progress of social welfare and also for developing or reforming social policy to cope with newly emerging social problems. While proposing a new social indicator framework based on the Organisation for Economic Co-operation and Development??s pressure-state-response (PSR) model, the paper argues that the new framework should be more than displaying static numbers but should use dynamic statistics revealing causes and effects and shedding light on social and policy changes.     

The Effectiveness of Risk Management: An Analysis of Project Risk Planning Across Industries and Countries

This article examines the effectiveness of current risk management practices to reduce project risk using a multinational, multi‐industry study across different scenarios and cultures. A survey was administered to 701 project managers, and their supervisors, in seven industries and three diverse countries (New Zealand, Israel, and Japan), in multiple languages during the 2002–2007 period. Results of this study show that project context—industry and country where a project is executed—significantly impacts perceived levels of project risk, and the intensity of risk management processes. Our findings also suggest that risk management moderates the relationship between risk level and project success. Specifically, we found that even moderate levels of risk management planning are sufficient to reduce the negative effect risk levels have on project success.     

Estimation of long-run inefficiency levels: a dynamic frontier approach

Cornwell, Schmidt, and Sickles (1990) and Kumbhakar (1990), among others, developed stochasticfrontier production models which allow firm specific inefficiency levels to change over time. These studies assumed arbitrary restrictions on the short-run dynamics of efficiency levels which have little theoretical justification. Further, the models are inappropriate for estimation of long-run efficiencies. We consider estimation of an alternative frontier model in which firmspecific technical inefficiency levels are autoregressive. This model is particularly useful to examine a potential dynamic link between technical innovations and production inefficiency levels. We apply our methodology to a panel of US airlines.     

Verallgemeinerte DEA-Modelle zur Performanceanalyse

Dyckhoff and Allen derived a generalisation of Data Envelopment Analysis (DEA) in order to measure ecological efficiency. This approach distinguishes between inputs and outputs of an activity on the one hand and their impact on the relevant evaluation criteria—referred to as efforts and benefits—on the other hand. Thereby, the current framework of the DEA for analysing the relative performance of productive units is fundamentally extended. The relevance of this framework is not limited to ecological aspects because many essential problems of DEA application can be solved. Against this background, the paper presents a formalisation of the generalised DEA, applies it to the well-known basic DEA models, and concretises these models for linear effort and benefit functions.     

佛教传入后志怪叙事性格的变化

随着佛教的传入与迅速发展,中国古代志怪小说从内容到形式,都经历了一场潜移默化的变革.主要表现在:形式上,从"史学"的一部分发展为注重故事性、趣味性的"文学";内容上,从对自然世界的关心转变为对人性的关心;结构上,从单线直叙完善为人物复杂,因果错综,情节曲折的志怪文学.这种变化兴盛于佛教在中国迅速扩大的晋唐之间,形成了不同于初期志怪的佛教类志怪,并推进了中国小说文学的发展.     

The Effect of Infancy Childcare Center Use and Maternal Employment on Toddlers’ Language Development in South Korea

Using first to fourth wave data of the Panel Study of Korean Children (PSKC), this study explores the effects of childcare center use, maternal employment, and other child and familial characteristics on the language development of toddlers in Korea. Among the 2078 families with children in the PSKC, those who completed the Receptive and Expressive Vocabulary Test at the fourth wave were selected, and a small number of disabled or prematurely born children were excluded. In addition, to clarify the effects of maternal employment, families with mothers who were either employed or unemployed for three consecutive years during the child's infancy were selected. Regression analysis showed that neither childcare center use nor maternal employment during infancy had significant effects on toddlers’ expressive and receptive vocabulary at the fourth wave. Family characteristics, such as household poverty and maternal education level, as well as child characteristics, such as gender and birth order, had significant effects on expressed vocabulary. However, only children's gender significantly affected the receptive vocabulary level of toddlers.     

The use of child care center for infants of dual-working families in Korea

Using the first and second wave data of the Panel Study of Korean Children (PSKC), which is comprehensive longitudinal data with a nationally representative birth cohort, this study explores whether and when dual-working families place their infants and toddlers in child care centers and what factors influence these families' selection process. Among the 2078 families examined in the PSKC, 466 dual-working families which had any kind of nonparental care arrangement for their very young children at the time of the second survey were included in the analysis. Since our research questions address when the use of child care centers occurred, an event history analysis was conducted. The results show that 32.4% of the families had placed their infants in child care centers prior to the second interview. Family structure and income variables (number of children, nonparental adults in the household, and household income), mother's education level, and the mother's number of working hours turned out to be significantly related to the probability of child care center use.     

Effects of the one-child family policy on second and third births in Hebei,Shaanxi and Shanghai

This paper uses the proportional hazards model to assess the effect of the Chinese one-child policy on second and third births. The differential effects of the policy between the urban and rural areas and by the sex of previous children are highlighted. First, the urban-rural differentials have increased much after the policy, suggesting a more rapid increase in the costs of children and stricter government controls in the urban areas. Second, the sex of children has become a more important factor after the policy. The considerably higher risks to a subsequent birth among sonless families indicate the persistent strong son preferences among Chinese parents, especially in less developed areas. Although son preferences seem suppressed in Shanghai, the higher risks to a second birth after the death of a son compared to a daughter are indicative of the son preferences even in Shanghai. Relaxation of the one-child policy may increase the Chinese fertility.
