Avowed Happiness in Confucian Asia: Ascertaining its Distribution,Patterns, and Sources

This study reviewed three philosophical accounts of happiness, and then tested those accounts with the Asiabarometer surveys conducted in six Confucian societies during the summer of 2006. Statistical analyses of these surveys reveal that East Asians tend to experience happiness to a greater extent when they experience enjoyment together with achievement and/or satisfaction. The preponderance of such multi-dimensional conceptions in all those societies poses a direct challenge to a single dimensional account of happiness in the West. The analyses also reveal that positive assessments of interpersonal relationships matter more than the amount of knowledge or wealth in living a happy life in Confucian societies.

Bayesian tests for unit root and multiple breaks

A Bayesian approach is considered for identifying sources of nonstationarity for models with a unit root and breaks. Different types of multiple breaks are allowed through crash models, changing growth models, and mixed models. All possible nonstationary models are represented by combinations of zero or nonzero parameters associated with time trends, dummy for breaks, or previous levels, for which Bayesian posterior probabilities are computed. Multiple tests based on Markov chain Monte Carlo procedures are implemented. The proposed method is applied to a real data set, the Korean GDP data set, showing a strong evidence for two breaks rather than the usual unit root or one break.     

A backward procedure for change-point detection with applications to copy number variation detection

Change-point detection regains much attention recently for analyzing array or sequencing data for copy number variation (CNV) detection. In such applications, the true signals are typically very short and buried in the long data sequence, which makes it challenging to identify the variations efficiently and accurately. In this article, we propose a new change-point detection method, a backward procedure, which is not only fast and simple enough to exploit high-dimensional data but also performs very well for detecting short signals. Although motivated by CNV detection, the backward procedure is generally applicable to assorted change-point problems that arise in a variety of scientific applications. It is illustrated by both simulated and real CNV data that the backward detection has clear advantages over other competing methods, especially when the true signal is short.

Vector error correction heterogeneous autoregressive forecast model of realized volatility and implied volatility

A vector error correction model is proposed for forecasting realized volatility which takes advantage of the cointegration relation between realized volatility and implied volatility. The model is constructed by adding a cointegration error term to a vector-and-unit-root version of the heterogeneous autoregressive (HAR) model of Corsi (2009 Corsi, F. 2009. A simple approximate long-memory model of realized volatility. Journal of Financial Econometrics 7 (2):174–96. [Google Scholar]). The proposed model is easier to implement, extend, and interpret than fractional cointegration models. A Monte Carlo simulation and real data analysis reveal advantages of the proposed model over other existing models of Corsi (2009 Corsi, F. 2009. A simple approximate long-memory model of realized volatility. Journal of Financial Econometrics 7 (2):174–96. [Google Scholar]), Busch Christensen and Nielsen (2011 Busch, T., B. J.

A practical extension of the generalized estimating equation approach for longitudinal data

Liang and Zeger (1986) proposed an extension of generalized linear models to the analysis of longitudinal data. In their formulation, a common dispersion parameter assumption across observation times is required. However, this assumption is not expected to hold in most situations. Park (1993) proposed a simple extension of Liang and Zeger's formulation to allow for different dispersion parameters for each time point. The proposed model is easy to apply without heavy computations and useful to handle the cases when variations in over-dispersion over time exist. In this paper, we focus on evaluating the effect of additional dispersion parameters on the estimators of model parameters. Through a Monte Carlo simulation study, efficiency of Park's method is compared with the Liang and Zeger's method.     

Swaying in time and space: the Chinese Diaspora in the Caribbean and its literary perspectives

Despite that the Chinese in the Caribbean, unlike Africans or East Indians, is vaguely impressive in terms of racial and social impact; their stance and viewpoint are quite unique and insightful. Willi Chen and Jan Lowe Shinebourne, representing Chinese Caribbean Diaspora, are impressive enough with its strong literary impact. They both show the ambivalence acquired in the process of ‘positioning’, as well as the strong heritage of their ancestral mother land of China. Chen’s work is characteristic with its neutral stance of Chinese characters, and Shinebourne makes her protagonists wander with intermingling sense of tradition and progression. This ambivalence, however, can become a positive sway between groups which may be different, conflictive, or even hostile to each other, and that sway can bring a righteous and truthful judgment to the matter. The Chinese Caribbean writings contribute with the dialectic philosophies included in and inherited from Chinese traditions.     

Comparison of Temperament and Character Between Early- and Late-Onset Korean Male Pathological Gamblers

Purposes  

We investigated differences in temperament and character between early and late onset Korean pathological gamblers to identify whether the age of onset of pathological gambling (PG) could discriminate PG subtypes, like in alcoholism.     

The Lifestyle, Commitment and Satisfaction among Male Workers in Tokyo

Abstract  This study examines the relationship between workers' lifestyle, organizational commitment, and satisfaction. First, this study describes the lifestyle, i.e. cluster of value orientations, of male workers in Tokyo. The sample of this study is 2,003 regular male private firm employees and public (government) employees aged 20-54 living in the Tokyo metropolitan areas. We measure attitudes of workers toward work and the place of work. The 33 measures of attitudes are analyzed by means of cluster analysis to construct typologies of lifestyle of workers. We obtained three clusters: cluster 1 (career-oriented generalists, i.e., company man), cluster 2 (stability-oriented family man), and cluster 3 (work-oriented specialist). Second, we found demographic differences among the three clusters. Workers in cluster 1 tend to be older. to be more university educated, to obtain higher income, and to have higher positions at their current job. Workers in cluster 2 are more likely to be young, to graduate from senior high school, and to be in the middle-income group. Workers in cluster 3 tend to graduate from special training school or university and to be in lower-income group. Finally, we found differences in organizational commitment and job satisfaction among the three clusters. Workers in cluster 2 are more likely than are those in the other two clusters to be dissatisfied with their current job. to have a lower level of identification with their current firm, and consequently to have a greater propensity to leave their present company.
