Dimensions of Family Conflict and Their Influence on Child and Adolescent Adjustment

Using the first (1987-1988) and second (1992-1994) waves of the National Survey of Families and Households, this study examines the concurrent and longitudinal influences of interparental conflict and parent-child conflict on child and adolescent adjustment. Analyses focus on 542 intact families, each with a randomly selected focal child aged 5 to 11 at time 1 and aged 10 to 17 at time 2. Results indicate that both parent-child and parent-adolescent conflict are critical predictors of children's and adolescents'socioemotional adjustment. Interparental conflict, by contrast, is less important for adjustment in middle and late childhood as well as in adolescence. The findings extend previous research by suggesting that the salience and threat of interparental conflict subside as children make the transition into adolescence.     

Distance sampling methodology

We consider the method of distance sampling described by Buckland, Anderson, Burnham and Laake in 1993. We explore the properties of the methodology in simple cases chosen to allow direct and accessible comparisons of distance sampling in the design- and model-based frameworks. In particular, we obtain expressions for the bias and variance of the distance sampling estimator of object density and for the expected value of the recommended analytic variance estimator within each framework. These results enable us to clarify aspects of the performance of the methodology which may be of interest to users and potential users of distance sampling.     

A graph-theoretical approach to the aggregation of individual preference orderings

A graph-theoretical approach as first outlined by Harary et al. is developed for solving the problem of aggregating a given set of individual preference orderings provided that no individual preferential judgment is inconsistent with the collective preference ordering obtained by aggregation.

Rural-Urban Differences and Their Amelioration

South Korean society is in transition toward a multicultural society. Integrating multicultural education into current citizenship education is challenging for the society. Historically, many national tragedies have created the unique characteristics of what being Korean means. South Korean social studies curriculum emphasized that Korea is a monolithic society with one language, one history, and one ethnicity. In recent years, however, the number of foreigners living in South Korea dramatically increases because of work, study, and marriage. As they become be members of Korean society, it is necessary that South Koreans acknowledge diverse groups in the society and revise a long-held belief about who we, as Koreans, are. To this end, the Korean social studies curriculum should include more information about as well as respect and promote ethnic, cultural, and social diversity. Social studies teachers should attempt various activities to promote students’ understanding of current social changes in South Korea.     

Bivariate exponential-type distributions with linear regression

Let Xbe a bivariate exponential-type random vector (BIDLIKAR, PATIL (1968)), than it is proved:

1. If P(X ≥0) = 1 is valid, then Xhas linear regression to both directions if and only if Xpossesses a symmetric Γ-distribution.

2. Xpossesses linear regression to both directions with constant regression coefficients (independent of the parameter vector ? of the exponential-type distribution (BIDLIKAR, PATIL (1968)) if and only if Xis normal distributed.
