Math Achievement and Children’s Savings: Implications for Child Development Accounts

In this study, we propose that children who have a savings account may be more likely to have higher math scores than children without a savings account. We find that children’s savings accounts are positively associated with math scores. Children with savings accounts on average score almost nine percent higher in math than children without a savings account. Further, results suggest that children’s savings accounts fully mediate the relationship between household wealth and children’s math scores. However, household wealth moderates the mediating relationship. We find math scores of low-wealth children increase by 2.13, middle-wealth children’s increase by 4.36, while high-wealth children’s increase by 6.59 points. Policy implications are discussed.     

Application of the Fuzzy Weighted Average in Strategic Portfolio Management*

We propose a systematic approach that incorporates fuzzy set theory in conjunction with portfolio matrices to assist managers in reaching a better understanding of the overall competitiveness of their business portfolios. Integer linear programming is also accommodated in the proposed integrated approach to help select strategic plans by using the results derived from the previous portfolio analysis and other financial data. The proposed integrated approach is designed from a strategy‐oriented perspective for portfolio management at the corporate level. It has the advantage of dealing with the uncertainty problem of decision makers in doing evaluation, providing a technique that presents the diversity of confidence and optimism levels of decision makers. Furthermore, integer linear programming is used because it offers an effective quantitative method for managers to allocate constrained resources optimally among proposed strategies. An illustration from a real‐world situation demonstrates the integrated approach. Although a particular portfolio matrix model has been adopted in our research, the procedure proposed here can be modified to incorporate other portfolio matrices.     

Mainstream and Marginal Newspaper Coverage of the 1995 Quebec Referendum: An Inquiry into the Functioning of the Canadian Public Sphere*

Cet article applique le concept habermassien de la sphère publique à l'examen des relations entre les journaux ethniques et grand public présents à Toronto. En particulier, cette étude analyse les éditoriaux parus au cours de l'année précédant le référendum de 1995 sur la souveraineté du Québec et en explique la couverture médiatique sur la base d'entretiens avec les rédacteurs en chef des journaux concernés. Pendant cette période, tous les journaux, sauf un, étaient antiséparatistes. Cependant, contrairement aux journaux grand public, les journaux ethniques se sont particulièrement attachés à des questions de survivance culturelle. Les approches des éditeurs sur la question de la souveraineté suggèrent qu'on ne peut ni parler de sphère publique unifiée ni de publics multiples et atomisés. Il y a plutôt des sphères publiques multiples - inscrites dans des tempo-ralités socio-économiques spécifiques - qui se recouvrent et se complètent. This article employs Habermas's concept of the public sphere in examining the relationship between ethnic and mainstream Toronto newspapers. In particular, the study analyses editorials in the year leading up to the 1995 Quebec referendum on sovereignty, and draws upon interviews with the newspaper editors in explaining the patterns of coverage. During the specified time period, all but one newspaper was anti-separatist. Unlike the mainstream papers, however, the ethnic presses stressed issues of cultural survival. The editors' approaches to the sovereignty question suggests that there is neither a single unified public sphere nor multiple discrete publics. Instead, there are multiple overlapping public spheres—embedded in particular socio-economic historical moments—that complement one another.     

Crisis,charisma, values,and voting behavior in the 2004 presidential election

This study extends Pillai and Williams [1998, Pillai, R., Williams, E.A., Lowe, K.B., & Jung, D.I. (2003). Personality, transformational leadership, trust, and the 2000 U.S. presidential vote. The Leadership Quarterly, 14, 161–192] and examines leadership in the context of the 2004 U.S. presidential election. Data were collected at two time periods from respondents in three locations across two major regions of the U.S. Our results indicate that respondents' perception of crisis was related to charismatic leadership in the negative direction for the incumbent George W. Bush and in the positive direction for the challenger John Kerry. For Bush and Kerry the relationship between crisis and voting behavior was mediated by charismatic leadership. For Bush, decisiveness was related to charismatic leadership, which in turn predicted voting behavior. For Kerry, decisiveness and charismatic leadership predicted voting behavior. Implications of the findings for leadership research, in particular with respect to an incumbent and the challenger to an incumbent leader, are discussed.     

Censored time series analysis with autoregressive moving average models

The authors consider time series observations with data irregularities such as censoring due to a detection limit. Practitioners commonly disregard censored data cases which often result in biased estimates. The authors present an attractive remedy for handling autocorrelated censored data based on a class of autoregressive and moving average (ARMA) models. In particular, they introduce an imputation method well suited for fitting ARMA models in the presence of censored data. They demonstrate the effectiveness of their technique in terms of bias, efficiency, and information loss. They also describe its adaptation to a specific context of meteorological time series data on cloud ceiling height, which are measured subject to the detection limit of the recording device.     

Least Trimmed Squares Estimator in the Errors-in-Variables Model

We propose a robust estimator in the errors-in-variables model using the least trimmed squares estimator. We call this estimator the orthogonal least trimmed squares (OLTS) estimator. We show that the OLTS estimator has the high breakdown point and appropriate equivariance properties. We develop an algorithm for the OLTS estimate. Simulations are performed to compare the efficiencies of the OLTS estimates with the total least squares (TLS) estimates and a numerical example is given to illustrate the effectiveness of the estimate.     

Multidimensional Inequality in South Korea: An Empirical Analysis

The objective of this study is to review the theoretical limitations of single dimensional approaches for measuring inequality and to prove the effectiveness and practicality of the concept of “multidimensional inequality” by analyzing the inequality embedded in Korean society. This study constitutes nine dimensions of inequality (income, education, health, employment, social capital, leisure, work‐family reconciliation, housing, and social security) and analyzes inequality through the lens of each dimension by using data from of the first to fifth wave of the Korea Welfare Panel Study. The findings show a high degree of correlation among the dimensions of income, education, health, and social capital. However, work‐family reconciliation and housing have a relatively low correlation with income and the other dimensions. Second, multidimensional disparities were found between the groups of gender, age, and region. In conclusion, this study found a high degree of overlap between the concepts of income‐oriented inequalities and the multidimensional inequality approach. By capturing the notions of the multidimensional disparities that exist in each of the different groups, this study confirmed the effectiveness of multidimensional inequality as a useful concept for informing the creation of social policy intervention to alleviate inequality.     

The Impact of Neo-liberalism on South Korea's Public Pension: A Political Economy of Pension Reform

This article examines the recent Korean pension reforms from a political economy perspective. It argues that these reforms are of particular interest because, unlike major pay-as-you-go pension schemes in Europe, the Korean pension scheme is a funded one and, therefore, is subject to market exposure. Also in contrast to the problems that public pension reforms have encountered in European and other OECD countries, especially 'blame avoidance', the more radical Korean reforms were implemented without significant challenge or resistance. First of all, the National Pension Scheme is described prior to the 1997 Asian economic crisis. Then the impact of this crisis on the Korean welfare state and, especially, its pension system are analysed. The main part of the article consists of a political economy of the pension reform process, in which the key roles of the international governmental organizations and the domestic neo-liberal policy elite are pinpointed. This neo-liberal ideology was critical in developing and sustaining an influential discourse on the 'crisis' in Korea's national pension fund. The article concludes by arguing, against the neo-liberal tide, for the inclusion of a pay-as-you-go element in the national pension in order to tackle escalating poverty in old age.     

Bewältigungs- und Aneignungsmuster staatlich geförderter Beschäftigung bei ehemaligen Langzeitarbeitslosen

The article analyses the experiences made in publicly subsidized employment by long-term-unemployed in theoretical and empirical perspectives. The heterogeneity of the investigated population requires a differentiation between various types of personal employment histories as well as the examination of patterns of coping with subsidized employment from a differential perspective: Only a subgroup of the target-group share the notions of normality on which its construction is based. Furthermore, the wage subsidy can fulfill different functions with regard to the recipient’s personal employment history. Finally, problematic employment situations can result in the termination of a subsidized employment relationship. Since heterogeneous groups of persons can be affected by a permanent exclusion from the labour market, it seems problematic to tackle the problems connected with this situation by applying a single labour market measure.     

Factors influencing resubstantiation of child neglect in South Korea: A comparison with other maltreatment cases

While a high prevalence of child neglect cases has been reported by Child Protective Services (CPS) in Western countries, child neglect cases reported to South Korea's Child Protection Agency (CPA) present different trends than those in Western countries. Nevertheless, child neglect is an understudied area within child welfare. Thus, a need exists to investigate the unique characteristics of child neglect cases substantiated by the CPA in Korea. This study investigates the unique characteristics of child neglect cases and examines how factors associated with the resubstantiation of these cases differ from those of other maltreatment cases. Using CPA administrative data, we employed a multilevel discrete‐time hazard analysis to analyze the risk and protective factors associated with the resubstantiation of child neglect cases and compared the results with other maltreatment cases. In both cases, younger children, perpetrators with alcohol problems, families receiving welfare, and months of agency operation were associated with resubstantiation. For child neglect cases, the provision of child and parent services, and CPAs located in metropolitan area were protective factors that reduced the risk of resubstantiation. The finding in this study highlights the need to expand the provision of services to child neglect cases to prevent resubstantiation.
