An Examination of the Conceptual Issues Involved in Developing Credit-Scoring Models

Multiple discriminant analysis (MDA) is frequently used to develop statistical credit-scoring models for loan evaluation purposes. Current legislative efforts to insure that credit is being granted in a nondiscriminatory manner have focused considerable attention on the reliability of such models. This article examines the theoretical requirements of the MDA model in the context of a realistic lending situation and illustrates the extent of bias when these theoretical assumptions are not fully met. The article concludes that failure to rigorously meet all the theoretical assumptions of the statistical model may not be as critical as insuring that credit managers fully understand the limitations of these types of decision tools. Furthermore, the evidence indicates that statistical models other than multiple discriminant analysis are possibly more relevant to the credit-granting decision.     

Asset Ownership of New Asian Immigrants in the United States

This study examined the asset ownership of Asian immigrants using a nationally representative sample of newly legalized immigrants (New Immigrant Survey). Findings revealed that ownership of a business or farm, financial assets, and home ownership were associated with socioeconomic, demographic, and acculturation variables. Family income, education, English fluency, and length of stay were significant in all types of asset ownership. Variances in asset ownership by ethnic groups exist. Asian Indians and Koreans had higher levels of business asset ownership. Korean, and Filipino immigrants were also more likely to be homeowners. Asian Indian and Chinese immigrants were more likely to own financial assets. Vietnamese lagged in business or farm and financial asset ownership. Findings provided insights into the investment decisions of new Asian immigrants for financial educators, researchers, and policymakers.     

Commercialization of Platform Technologies: Launch Timing and Versioning Strategy

Many emerging entrepreneurial applications and services connect two or more groups of users over Internet‐based information technologies. Commercial success of such technology products requires astute business practices related to product line design, price discrimination, and launch timing. We examine these issues for a platform firm that serves two markets—labeled as user and developer markets—such that the size of each market positively impacts participation in the other. In addition, our model allows for sequential unfolding of consumer and developer participation, and for uncertainty regarding developer participation. We demonstrate that product versioning is an especially attractive strategy for platform firms, that is, the trade‐off between market size and margins is tilted in the direction of more versions. However, when expanding the product line carries substantial fixed costs (e.g., marketing cost, cost of additional plant, increased distribution cost), then the uncertainty in developer participation adversely impacts the firm's ability to offer multiple versions. We show that for established firms with lower uncertainty about developer participation, the choice is essentially between an expanded or minimal product line. Startups and firms that are entering a new product category are more likely to benefit from a “wait and see” deferred expansion strategy.     

An intelligent workstation controller for integrated planning and scheduling of FMS cell

This paper presents an experimental design developed to determine a combination of robust planning and scheduling rules for an intelligent workstation controller (IWC). The IWC is used as part of the control system for an automated flexible manufacturing system. A three-level hierarchical control structure (shop, workstation and equipment)is adopted in order effectively to control a shop-floor. At the top level is a shop controller which receives orders and their associated manufacturing information, and manages interactions among workstations. The IWC defines and resolves the production control activities necessary to coordinate a group of equipment controllers so as to ensure the completion of orders. Specifically, the IWC is responsible for selecting a specific process routeing for each part, allocating resources, scheduling and coordinating the activities across the equipment, monitoring the progress of activities, detecting and recovering from errors, and preparing reports. These activities are accomplished using planning, scheduling, and execution functions. In order to demonstrate the effectiveness and robustness of the IWC, all the controllable and uncontrollable factors need to be identified and detailed. Controllable factors are those which are set by the controller and cannot be directly affected by the production environment. Uncontrollable factors are those which vary with the production environment and cannot be directly changed by the controller developer. The objective of the paper is to illustrate how a good set of controllable factors that dictate the IWC's effectiveness and robustness over various uncontrollable factors can be determined. Due to the number of possible combinations of all the factors, a complete validation of the effectiveness and robustness of the IWC is extremely time consuming and far beyond the scope of this paper. Therefore, a few planning and scheduling strategies are selected and a formal experiment is conducted. The experiment illustrates how significant performance dependencies for various planning and scheduling strategies can be identified.     

South Korean women leaders’ struggles for a work and family balance

The purpose of this study was to explore the lived experience of women in leadership in Korea and to identify challenges and opportunities that they face in the process of balancing work and family life and developing leadership as women in the uniquely challenging Korean workplace where they face organizational and cultural constraints. Critical to this investigation was the understanding of concepts frequently represented in the previous literature about women in leadership: work–family life balance, women’s leadership development, and the cultural context. In-depth interviews were conducted with 18 women leaders selected through a purposeful and snowball sampling method. A thematic analysis of the interview data generated six themes including: (a) commitment to work, (b) struggles for a balance, (c) defining success, (d) gender identity, (e) being a role model, and (f) need for support. Based on the findings, we provide implications for research and practice.     

Work-to-family conflict and the family dinner: what makes a difference?

Despite the abundant benefits that have been associated with family meals, families report that they share fewer meals together than in the past. Although parents' work (e.g., work hours) is recognized as a barrier to family meals, the role of the individual in determining family meal frequency has received relatively little attention. With this in mind, this study investigated two important person factors that may aggravate or attenuate the negative relationship between work-to-family conflict (WTFC) and family dinner frequency using survey data from employed parents (n =206). Specifically, parents' negative affectivity (NA) and family meal atmosphere were examined as moderators. As hypothesized, the relationship between WTFC and family dinner frequency was stronger for high-NA individuals than for low-NA individuals. However, no support was found for the moderating role of family meal atmosphere. Findings suggest that WTFC may be more deleterious for high-NA individuals due to their tendency to strongly react to stressors and highlight the necessity to consider both situational and individual factors in understanding work-family experiences.     

Women watching together: An ethnographic study of Korean soap opera fans in the US

To Kill a Mockingbird is a classic of American cultural–legal studies, and it offers in Atticus Finch an iconic hero who, as Stephen Lubet suggests, is popular culture's most important embodiment of lawyerly virtue. As other scholars have noted, however, To Kill a Mockingbird is not just, or primarily, a law story. Rather, Scout Finch's portrait of Atticus as a father is regarded by many as the key to the text's cultural resonance. Told as a daughter's memory of her father, her brother, and the town in which she grew up, the text frames the era's conflicts over race, gender, and justice through the lens of Scout's admiration for Atticus. From our perspective, however, it is the conjunction of lawyer and father that fuels To Kill a Mockingbird’s appeal and importance, and in this paper we argue that such a conjunction, particularly in its filmic incarnation, provides an opportunity to explore the role that fathers and fatherhood play in cultural imaginings of law and in exemplifying the various faces of law's power. We argue that Atticus Finch is a father/lawyer committed to a particular vision of fatherhood and law, one in which both can transcend, if not transform, the context in which they exist, one in which orienting oneself to the future takes precedence over controlling the present, one in which the temporal horizon of law and fatherhood is kept firmly in view. In the figure of Atticus, To Kill a Mockingbird suggests that law and fatherhood are powerful and yet limited in their power, and that both exist in the present but are oriented towards an as yet unrealized future.     

Introducing the Historical Thinking Practice of Contextualizing to Middle School Students

This article describes the design of a social studies unit about the Johnstown Flood of 1889 with a particular emphasis on how specific unit resources engaged middle school students in learning about the geographical and historical context of Johnstown, Pennsylvania. We also report on how the resources supported the teaching and learning of the historical thinking practice of contextualizing.     

Prevalence of Sexual Dysfunction and Associated Risk Factors in Middle-Aged and Elderly Korean Men in Primary Care

Although several studies have individually investigated the risk factors for erectile dysfunction (ED), premature ejaculation (PE), and late-onset hypogonadism (LOH), few studies have considered ED, PE, and LOH as categories of sexual dysfunction (SD) within the same population. We therefore aimed to investigate the prevalence of SD and its associated risk factors among men in primary care. Study participants were enrolled by 18 family physicians from 15 hospital-based family practices in Korea between August 2010 and May 2011. Participants answered a questionnaire regarding their demographic characteristics and lifestyle factors as well as the Korean versions of the Androgen Deficiency in the Aging Male, the International Index of Erectile Function, and the Premature Ejaculation Diagnostic Tool questionnaires. SD prevalence was 64.9% among study participants who were ≥ 40 years of age. ED prevalence was 43.7%, PE prevalence was 38.6%, and LOH prevalence was 16.8%. SD prevalence was significantly associated with increased age, overweight, hypertension, diabetes, and depression. These findings highlight the importance of screening questions for SD in primary care, especially among older male patients with the identified risk factors.     

The effects of child maltreatment on childhood behaviour problems in South Korea: findings from the fifth Korea Child and Youth Panel Survey (the 2014 KCYPS)

The study examines the effects of child maltreatment on children behavioural problems in South Korea. We found that 11.5% of children experienced physical abuse, 28.7% experienced emotional abuse and about 35% experienced neglect. After controlling for all socio-demographic factors, children who experienced physical abuse, emotional abuse and neglect were more likely to develop internalised as well as externalised behavioural problems such as depression, aggression, underage smoking, underage drinking and engaging in cyber delinquency. The results point towards a need to develop social welfare interventions to mitigate physical/emotional abuse and neglect so as to prevent behavioural problems in South Korean children.
