Examining cultural and gender similarities and differences in college students’ value of communication skills in romantic relationships

This study assessed and compared the communication skills that native Chinese and native American college students value in the context of romantic relationships. A total of 319 Chinese and 262 American college students responded to questionnaires that assessed the values they placed on six different communication skills. The results showed that the American students valued four of six communication skills more than the Chinese students (i.e. conversational, informative, listening, and narrative skills). The men and women in both cultural groups valued affective communication skills more than instrumental communication skills. In both cultural groups, women placed greater value on affective communication skills than men. The findings also showed a significant mediating effect of gender orientation (masculinity and femininity) on the value placed on communication skills and a significant effect of self-construal, which mediated between nationality and the value assigned to communication skills.     

Statistical Estimation of the Casual Effect of Social Economy on Subjective Well-Being

It is well known that measuring the noneconomic outcomes produced by social economy organizations is fairly difficult and complex. Usually, social economy organizations feature participatory and democratic decision-making processes that help create social capital and relational goods, and they are interested in social integration; accordingly, they tend to create an organizational culture that encourages their workers to contribute to local communities. Therefore, the hypothesis that the increased activities of social economy organizations have a causal effect on the subjective well-being of the people living near those organizations is highly plausible. In this paper, we estimate the causal effect and attempt to test the hypothesis statistically by using a dataset called the “Seoul Survey,” which provides observations on the subjective well-being of 45,496 citizens living in Seoul and the size of social economy organizations. Controlling for variables at the district level and the appropriate socioeconomic characteristics of each individual in the dataset, we find that the size of social organizations is highly significant.     

The Role of Father’s Occupation on Intergenerational Educational and Occupational Mobility: The Case of Second‐Generation Chinese Americans in New York1

A considerable body of research has found a positive relationship between parents’ socioeconomic status and children’s educational achievement and attainment. The predictive role of parents’ socioeconomic status generally applies for most racial and ethnic groups, but that association does not always hold for groups that exhibit high levels of education, such as Asian Americans. This article considers the role of parents’ education and occupation on children’s educational and occupational attainment for Chinese Americans aged 18–32. The results corroborate the positive link between parents’ socioeconomic status and children’s educational and occupational attainments. Children of professionals command an educational and occupational advantage over children of entrepreneurs and children of manual workers. Yet, the children of entrepreneurs attend selective colleges and obtain professional occupations in proportions closely following those of the children of professionals. Although the educational attainments between the fathers who worked as entrepreneurs and those fathers engaged in manual work were comparable, it was the children of entrepreneurs who surpassed the children of manual workers with respect to educational and occupational achievement and attainment. This suggests that immigrant entrepreneurship contributes in the upward educational and occupational mobility of the children of entrepreneurs.     

Empirical likelihood based diagnostics for heteroscedasticity in partially linear errors-in-variables models

A standard assumption in regression analysis is homogeneity of the error variance. Violation of this assumption can have adverse consequences for the efficiency of estimators. In this paper, we propose an empirical likelihood based diagnostic technique for heteroscedasticity in the partially linear errors-in-variables models. Under mild conditions, a nonparametric version of Wilk's theorem is derived. Simulation results reveal that our test performs well in both size and power.     

Priority,solidarity and egalitarianism

We provide alternative axiomatic characterizations of the extended egalitarian rules (Moreno-Ternero and Roemer, Econometrica 74:1419–1427, 2006) in a fixed-population setting of the canonical resource allocation model based on individual capabilities (output functions). Our main axioms are disability monotonicity (no reduction in the amount of resources allocated to an agent after she becomes more disabled) and agreement (when there is a change in agents’ capabilities or total resources, all agents who remain unchanged should be influenced in the same direction: all unchanged agents get more or all get less or all get the same amount as before).     

How many people participated in candlelight protests? Counting the size of a dynamic crowd

The recent controversy about the size of crowds at candlelight protests in Korea raises an interesting question regarding the methods used to estimate crowd size. Protest organizers tend to count all participants in the event from its start to finish, while the police usually report the crowd size at its peak. While several counting methods are available to estimate the size of a crowd at a given time, counting the total number of the participants at a protest is not straightforward. In this paper, we propose a new estimator to count the total number of participants that we call the size of a dynamic crowd. We assume that the arrival and departure times of the crowd are randomly observed and that the number of the attendees in the crowd at a specific time is estimable. We estimate the number of total attendees during the entire gathering based on the capture-recapture model. We also propose a bootstrap procedure to construct a confidence interval for the crowd size. We demonstrate the performance of the proposed method with simulation studies and the data from Korea''s March for Science, a global event across the world on Earth Day, April 22, 2017.     

The distributive impact of private pensions in the context of the institutional designs of public pension systems across OECD countries

Income inequality has been increasing across the developed world for the last few decades. The welfare state has played an important role in reducing income inequality, but it has now entered into an era of transformation. The shift from public to private pension schemes is one of the main policy instruments in this shift. An increase in private pensions is expected to create an increase in income inequality. Therefore, using data from OECD SOCX, this study examined how the effect of private pensions on income inequality might be changed by the institutional design of public pension systems. The results suggest that the effect of private pensions differs when the institutional design of the public pension system is considered. An increase in private pensions is related to an increase in income inequality when the public pension has a low level of coverage and a high level of earnings‐relatedness.     

Bayesian Time Series Analysis of Structural Changes in Level and Trend

In this article we consider the problem of detecting changes in level and trend in time series model in which the number of change-points is unknown. The approach of Bayesian stochastic search model selection is introduced to detect the configuration of changes in a time series. The number and positions of change-points are determined by a sequence of change-dependent parameters. The sequence is estimated by its posterior distribution via the maximum a posteriori (MAP) estimation. Markov chain Monte Carlo (MCMC) method is used to estimate posterior distributions of parameters. Some actual data examples including a time series of traffic accidents and two hydrological time series are analyzed.     

A measure and a graphical method for evaluating slope rotatability in response surface designs

A measure for evaluating slope rotatability over all directions in response surface designs, is proposed. This measure is used to form slope variance dispersion graph evaluating the overall slope rotatability and the slope estimation capability of an experimental design throughout the region of interest. This graph allows for an easy comparison of competing designs.     

Social Capital Accessibility of Intermarrieds

Grounded in Bourdieu’s social capital theory, the study’s purpose was to investigate social capital accessibility of intermarrieds compared to intramarrieds. Using the 2001 Integrated Health Interview Series data, two generalized linear models with Poisson distribution and identity link were performed: Model 1 compared intermarrieds to intramarrieds; Model 2 compared specific types of intermarrieds to intramarrrieds. Model 1 indicated that intermarrieds had less accessibility to social capital than intramarrieds. Model 2 indicated that intermarrieds, particularly interracially marrieds, had less social capital accessibility than intramarrieds, although the influence was moderate. Social capital accessibility of the interethnically or internationally marrieds was not significantly different from that of intramarrieds. Findings provide partial support to previous research concerning a lack of social capital accessibility for intermarrieds.
