Work Roles, Management and Perceived Well-being for Married Women within Family Businesses

The study uses the National Family Business Survey and is grounded in the systemic Sustainable Family Business Model. It investigated the relationship between management activity of married women within family businesses and perceived well-being controlling for work roles, family context, personal and financial resources. Statistical analyses indicated that successfully achieving the most important family goal was positively related to management activity. Low-income women performed more management than did those with other income levels. Successfully achieving family goals, having lower education, less competition between family and business resources, no family cash flow problems, and higher management activity contributed to positive perceived well-being. Well-being increased at a decreasing rate as income increased.This study reports results from the Cooperative Regional Research Project, NE-167R, ‘Family Businesses: Interaction in Work and Family Spheres,’ partially supported by the Cooperative States Research, Education and Extension Service, U.S. Department of Agriculture, and the Experiment Stations at University of Hawaii at Manoa, University of Illinois, Purdue University (Indiana), Iowa State University, Michigan State University, University of Minnesota, Montana State University, University of Nebraska, Cornell University (New York), North Dakota State University, The Ohio State University, The Pennsylvania State University, Texas A & M University, Utah State University, The University of Vermont, University of Wisconsin-Madison, and the Social Sciences and Humanities Research Council of Canada (for The University of Manitoba).     

Reliable Supply Chain Network Design

Risk management in supply chains has been receiving increased attention in the past few years. In this article, we present formulations for the strategic supply chain network design problem with dual objectives, which usually conflict with each other: minimizing cost and maximizing reliability. Quantifying the total reliability of a network design is not as straightforward as total cost calculation. We use reliability indices and develop analytical formulations that model the impact of upstream supply chain on individual entities’ reliability to quantify the total reliability of a network. The resulting multiobjective nonlinear model is solved using a novel hybrid algorithm that utilizes a genetic algorithm for network design and linear programming for network flow optimization. We demonstrate the application of our approach through illustrative examples in establishing tradeoffs between cost and reliability in network design and present managerial implications.     

Majoritarian Management of the Commons

This article analyzes usage of a common property resource, "the commons," under collectivization as compared with more familiar privatization institutional arrangements. Particular emphasis is on majority decision rules. When separate majority coalitions may authorize simultaneous usage of a common resource, total value is dissipated, but the interdependencies introduced by possible membership in differing coalitions to an extent reduce the incentives for exploitation. The formal analysis is analogous to that familiar in Cournot-Nash duopoly-oligopoly models but with differing efficiency implications. The argument has relevance for differential-benefit public spending from general tax sources, as well as other applications.     

Stimulus-Stimulus Pairing and Subsequent Mand Acquisition of Children with Various Levels of Verbal Repertoires

Effects of a stimulus-stimulus pairing procedure on the subsequent acquisition of mand operants were investigated. An attempt was made to shape novel sounds that emerged through the pairing procedure into a mand. Six children, aged two to five years, with moderate to severe language and communication delays, participated. Two conditions were used following the pairing condition: postpairing and direct reinforcement. The emergence of mands was compared across these conditions. An additional analysis was made of the relation between participants'' baseline verbal repertoires and the effects of the pairing and the emergence of mands. Results indicate the possibility of stimulus control from a stimulus-stimulus pairing to mand as shown in two of the participants who had demonstrated high rates of vocal play and low to no verbal repertoire prior to this study. Target vocal sounds during postpairing and direct reinforcement condition remained at zero to low levels for participants with high verbal repertoire and little vocal play, warranting future studies on relations between the pre-existing verbal repertoire and the effectiveness of stimulus-stimulus pairing.     

The Challenges of Governing Biotechnology in Korea

This paper explores the development of biotechnology governance and current challenges to its improvement in Korea. It aims to identify what element would be crucial to foster an effectively working system of biotechnology governance in Korea. The analysis is focused on two cases, the legislation of the Bioethics and Biosafety Act, and the development of ethical, legal, and social implications (ELSI) research. Our analysis finds that communication and consensus building between scientists and bioethics advocates in a broader sense is critical for improved governance. During the prolonged dispute over this legislation, the stakeholders advocating scientific advancements and those emphasizing the importance of ethics did not reach an agreement, which was reflected in the limitations of the act. The nascent ELSI research attempted to facilitate interdisciplinary communication and understanding between biotechnology scientists and those in humanities and social sciences, but was met with only limited success. Good governance of biotechnology requires scientists and other stakeholders to willingly comply with regulations and internalize certain norms. Based on our experience in ELSI research, a few suggestions are made to contribute to this end.     

Gender Differences in Perceived Business Success and Profit Growth Among Family Business Managers

Using data from the 1997–2000 National Family Business Surveys (NFBS), this study investigated the effect of gender on business success and profit growth among family businesses. The Ordinary Least Squares (OLS) results indicate that all else being equal, female managers perceived their businesses as more successful than male managers, and they reported more profit growth between 1996 and 1999 than male managers. The results of the dummy variable interaction approach also show that a differential response existed in profit growth over time between female and male managers in relation to health status, business liabilities, business size, and whether the business was home-based. This study concludes that there are many distinct differences between male and female managers in business performance.     

Penalized regression models with autoregressive error terms

Penalized regression methods have recently gained enormous attention in statistics and the field of machine learning due to their ability of reducing the prediction error and identifying important variables at the same time. Numerous studies have been conducted for penalized regression, but most of them are limited to the case when the data are independently observed. In this paper, we study a variable selection problem in penalized regression models with autoregressive (AR) error terms. We consider three estimators, adaptive least absolute shrinkage and selection operator, bridge, and smoothly clipped absolute deviation, and propose a computational algorithm that enables us to select a relevant set of variables and also the order of AR error terms simultaneously. In addition, we provide their asymptotic properties such as consistency, selection consistency, and asymptotic normality. The performances of the three estimators are compared with one another using simulated and real examples.     

Welfare losses due to monopoly: Korea's case

This paper estimates the negative effects of monopolies in Korea by measuring welfare loss due to monopolies. The results of this analysis reveal the following policy implications: (1) Welfare loss caused by monopolization represented was 7.56% of the gross value of shipments of 1998. (2) Welfare loss is greater in a firm whose monopoly power is greater. This result supports Leibenstein's research [Leibenstein, H. (1966). Allocative efficiency vs. X-efficiency. American Economic Review, 56(3), 391–415] that a firm with greater monopoly power will be more X-inefficiency. (3) Social cost for welfare loss in Korea is higher than that of the U.S. and Japan. In conclusion, it suggests that the government must implement stronger policies to regulate monopoly and promote competition.     

A cohort analysis of Korean immigrants' class backgrounds and socioeconomic status in the United States

"In this article, I first survey briefly the history of Korean immigration to the United States from 1903 to the present. Second, I explain the motivations and entry mechanisms that brought Korean immigrants into the United States. Third, I document and explain the changes in the class backgrounds of Korean immigrants during the last three decades. Finally, I examine how such changes have affected the patterns of social and economic adaptation among the different waves of immigrants."
