Child maltreatment in South Korea: An ecological systems analysis

This article reviews risk factors associated with child maltreatment in South Korea within the context of the ecological system theory. Although child maltreatment is a serious concern in South Korea, understanding of this phenomenon is limited because most of the empirical studies address individual characteristics and few consider broader ecological contexts. This review integrates empirical findings on the risk and protective factors associated with child maltreatment in South Korea within the context of micro- (parent-child relationship, intergenerational transmission of abuse, and domestic violence), meso- (interactions between child-teacher and child-parent), exo- (mothers' employment and parents' socio-economic status), macro- (drinking culture and corporal punishment), and chrono-system (Asian economic crisis) levels.     

Maltreatment of children with developmental disabilities: An ecological systems analysis

The purpose of this review is to understand the risk factors for maltreatment of children with developmental disabilities. Using the Bronfrenbrenner's (1976, 1977) ecological systems framework, the authors examine how socio-demographic characteristics (age, gender, and special education), micro- (parent-child relationship and domestic violence), exo- (parenting stress, parents' social support, and area of residence), and macrosystems level (culturally defined parenting practices) factors influence or inhibit maltreatment of children with disabilities. The authors highlight major implications for practice and policy for maltreated children with disabilities.     

Inter-organizational information systems visibility in buyer–supplier relationships: The case of telecommunication equipment component manufacturing industry

The concept and operation of supply chain (SC) visibility remain underexplored questions in supply chain management, as is the question of the facilitating role of inter-organizational information systems (IOIS) in achieving SC visibility. This paper seeks to elaborate on the novel concept of IOIS visibility and to explore the antecedents and consequences of IOIS visibility. Investigating SC cooperation from the perspectives of both partners (buyers and suppliers) is important, especially when channel partners depend on each other and when asymmetries in IOIS visibility can exist.     

Propaganda or public relations campaign? International communication on the war against Iraq

Cross-cultural survey on the war against Iraq from different cultures may help to assess whether the public relations war has succeeded or failed. Overall the public of the U.S. and the U.K. formed similar evaluations of the war; whereas South Korean opinion was lay on the opposite side of the continuum. The present study suggests that public relations campaigns administered by the U.S. government did not generate favorable opinions in countries other than the U.S.     

Construction of central composite designs for balanced orthogonal blocks

Box & Hunter (1957) recommended a set of orthogonally blocked central composite designs (CCD) when the region of interest is spherical. In order to achieve rotatability along with orthogonal blocking, the block size for those designs becomes unequal and it may not be attractive or practical to use such unequally blocked designs in many practical situations. In this paper, a construction method of orthogonally blocked CCD under the assumption of equal block size is proposed and an index of block orthogonality is introduced.     

Understanding the antecedents of aggressive behavior in Persian Gulf War veterans within individual,interpersonal, and community contexts

ABSTRACT

The present study applies the social-ecological framework to examine multiple level correlates of aggressive behavior of veterans of the first Gulf War in 1991. Data were collected from the VA‘s Persian Gulf Family Support Programs (PGFSP), and the sample includes 1,519 veterans who participated in the PGFSP. At the individual level, the study finds that younger and female veterans and those with higher self-esteem were less likely to report displaying aggressive behavior. At the interpersonal level, veterans who displayed misconduct in the home are more likely to display aggressive behavior. At the community level, veterans who were in the Air Force was less likely, while those in the Marines were more likely to be aggressive. Implications for practice are discussed.     

Importance of pension income of elderly households in Korea and related factors

Utilising the 2014 Household Income and Expenditure Survey of Korea, this study examined the importance of pension incomes for elderly-headed households in Korea and the influence of other income sources and socio-demographic factors on pension income. It was found that 64.8% of those surveyed received pension income, which accounted for 12.4% of total income on average. As age increased, the importance of pension income increased. Pension income receipt and amount were affected by household size, gender, age, educational level and home ownership. Policymakers could use the factors identified in this research to develop effective and selective pension policies.     

Dependence Models Arising from the Lagrangian Probability Distributions

In this article, we propose a method based on the Lagrangian probability distributions for developing new dependence models. Specifically, a generalized Poisson–gamma dependence model is derived. The maximum likelihood estimation (MLE) technique is proposed for estimating the dependence model parameters. Application of the generalized Poisson–gamma dependence model is illustrated by using an operational risks dataset.     

Conditions of Slope-Rotatability for Third-Order Polynomial Regression Models

In experimental design for response surface analysis, it is sometimes of interest to estimate the difference of responses at two points. If differences at points close together are involved, the design that reliably estimates the slope of the response surface is important. In particular, Hader and Park (1978 Hader , R. J. , Park , S. H. ( 1978 ). Slope-rotatable central composite designs . Technometrics 20 : 413 – 417 .[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) suggested the concept of slope-rotatability and studied slope rotatable central composite designs. Until now, many response surface designs including central composite designs have been suggested for fitting second order response surface models. However, we often need to fit third-order polynomial regression models. In this article, we suggest extended central composite designs (ECCDs) to fit third-order models and find the necessary and sufficient conditions for slope-rotatability over all directions in the third-order polynomial models.
