Subjective utility with upper and lower probabilities on finite states

This article is concerned with thresholds of discrimination of preference judgments under uncertainty. We establish an axiomatic characterization for a threshold representation, where thresholds are represented by inexact measurement of subjective probabilities, i.e., upper and lower probabilities. Since upper and lower probabilities need not be additive, the representational form adopts the Choquet integration.     

Communicating Actionable Risk for Terrorism and Other Hazards⋆

We propose a shift in emphasis when communicating to people when the objective is to motivate household disaster preparedness actions. This shift is to emphasize the communication of preparedness actions (what to do about risk) rather than risk itself. We have called this perspective “communicating actionable risk,” and it is grounded in diffusion of innovations and communication theories. A representative sample of households in the nation was analyzed using a path analytic framework. Preparedness information variables (including content, density, and observation), preparedness mediating variables (knowledge, perceived effectiveness, and milling), and preparedness actions taken were modeled. Clear results emerged that provide a strong basis for communicating actionable risk, and for the conclusion both that information observed (seeing preparedness actions that other have taken) and information received (receiving recommendations about what preparedness actions to take) play key, although different, roles in motivating preparedness actions among the people in our nation.     

Influence in covariance structure analysis: with an application to confirmatory factor analysis

Influence functions are derived for the parameters in covariance structure analysis, where the parameters are estimated by minimizing a discrepancy function between the assumed covariance matrix and the sample covariance matrix. The case of confirmatory factor analysis is studied precisely with a numerical example. Comparing with a general procedure called one-step estimation, the proposed procedure has two advantages:1) computing cost is cheaper, 2) the property that arbitrary influence can be decomposed into a fi-nite number of components discussed by Tanaka and Castano-Tostado(1990) can be used for efficient computing and the characterization of a covariance structure model from the sensitivity perspective. A numerical comparison is made among the confirmatory factor analysis and some procedures of ex-ploratory factor analysis by using the decomposition mentioned above.     

Constructing Co-governance between Government and Civil Society: An Institutional Approach to Collaboration

The aim of this paper is to analyze how civil society organizations (CSOs) collaborate with both developed and developing governments in Asia through institutional processes. It argues that in developed countries, institutional arrangements have a positive impact on collaboration. Favourable administrative governance can create collaboration between governments and CSOs. This paper reports on 3,944 studies of CSOs from 2004 to 2009 in Tokyo, Seoul, Manila, and Dhaka. CSOs in Tokyo have better combined collaborative and institutional processes than those in the other three cities. Governance in Seoul is more polarized than in the other cities, and in both Manila and Dhaka, despite there being a high degree of institutionalized relations between CSOs and the government, their collaboration is low. This research also finds that intermediary institutions between governments and CSOs play a role in co-governance.     

Income Comparison as a Determining Mechanism of Class Identification: A Quantitative and Simulation Study Using Japanese Survey Data

This paper questions whether personal income comparison explains the distributive gap between income and class identification by exploring the following two issues: empirical validity of income comparison as the determinant of class identification, and theoretical validity of income comparison for the distributive gap. For the first issue, we conduct a statistical analysis using data from the Social Stratification and Social Mobility surveys (1975–2005), and the Stratification and Social Psychology-I survey (2010). We find that the criteria for choosing reference groups changed historically from residential proximity to occupational equality. In addition, income comparison with sensitive to lower-income possessors and a distorted perception of income difference significantly affected class identification, except for the year of 1985. The simulation analysis employed to examine the second issue clarified that income comparison with the above-mentioned features yields a less skewed distribution compared to that of class identification. The data also indicates that the empirical conditions of income are satisfied for realization of this result. Thus, we could ascertain empirical and theoretical validity of income comparison as explanation for the distributive gap between income and class identification.     

KAIGAI-SHIJO Socialization in Toronto

Abstract  This article is based on a study of kaigai-shijo (children of Japanese temporary overseas residents) in Toronto, Canada. Although the theme of kikoku-shijo (returnee children) has been studied in considerable detail by Japanese (and a few American) scholars, the phase that precedes the return to Japan, that is, the children's experience while overseas has been relatively neglected. The article argues that kaigai-shijo are not only a subject worth studying in their own right, but that understanding their experience is crucial in order to fully appreciate the phenomenon of kikoku-shijo . The researcher conducted a study of kaigai-shijo in Toronto, focusing on their patterns of socialization. While taking into account findings from the few previous studies on kaigai-shijo , this study used concepts from the North American literature on socialization and ethnic groups studies. kaigai-shijo socialization was thus conceptualized as the combination of two processes: the adoption of host cultural patterns, and the retention of Japanese cultural patterns. Three main variations in kaigai-shijo socialization were found: 1) 'Host culture oriented', 2) Japanese culture-oriented, and 3) 'dual'. Some of the most relevant factors in explaining these variations were the age of the child (at the time of departure from Japan and at the time of the research), the parents' strategy of adaptation, and the length of stay in the host country (actual and remaining).     

Quadratic perturbation expansions of certain functions of eigenvalues and eigenvectors and their application to sensitivity analysis in multivariate methods

Tanaka (1988) lias derived the influence functions, which are equivalent to the perturbation expansions up to linear terms, of two functions of eigenvalues and eigenvectors of a real symmetric matrix, and applied them to principal component analysis. The present paper deals with the perturbation expansions up to quadratic terms of the same functions and discusses their application to sensitivity analysis in multivariate methods, in particular, principal component analysis and principal factor analysis. Numerical examples are given to show how the approximation improves with the quadratic terms.     

Simple Computation of Maximum Likelihood Estimates in Latent Class Model with Equality and Constant Constraints

A simple computational method for estimation of parameters via a type of EM algorithm is proposed in restricted latent class analysis, where equality and constant constraints are considered. These constraints create difficulty in estimation. In order to simply and stably estimate parameters in restricted latent class analysis, a simple computational method using only first-order differentials is proposed, where the step-halving method is adopted. A simulation study shows that in almost all cases the new method gives parameter sequences monotonously increasing the Q-function in the EM algorithm. Analysis of real data is provided.     

Repeated Reinterpretation of Civil Society: On the Intellectual Context of Niklas Luhmann's Sociological Theory

This article explains the intellectual context of Niklas Luhmann's sociological theory. Although Luhmann's theory is well known for its highly abstract features, this does not mean that the theory results from his references to the latest general systems theory, which has been the primary focus of previous literature. That said, no social theory is produced in a vacuum. Even if a theorist attempts to construct a general sociological theory to explain every social phenomenon, that theory is necessarily influenced by the theorist's prejudices. Therefore, social theory must be contextualized both to estimate its biases and to limit its scope. This study shows that Luhmann's systems theory is constructed through a struggle with the issues of his day. First, it notes that the question of how to conceptualize modern civil society was widely shared by German intellectuals from the late 1950s to the 1970s and that the question created a certain discourse field. Second, Luhmann's theoretical conception is contextualized in that field of discourse, and the central role of both the concept of functional differentiation and the concern with border maintenance in his theory-building is explained in comparison with the work of contemporary intellectuals. To deepen our analysis, this article reconstructs Schmitt's interpretation and criticism of civil liberalism and describes Luhmann's struggle with it. Finally, by analyzing the Gesellschaftswissenschaften of Robert von Mohl, one of the founders of civil liberalism, this article argues that Luhmann's sociology can be characterized as an attempt to rehabilitate civil liberalism.
