Optimally Scaled Quality-of-Life Indicators

When studying quality of life, researchers have to rely on the subjective evaluations, which are typically categorized, collected in surveys. When statistical analysis are applied to these data, they used to apply the simplistic approach including (i) direct quantification, which assigns discrete numerical values to ordinal response scale, and (ii) complete-case analysis, which discards all observations selecting any of the off-scales choices like Dont Know No Answer from the analysis. The present paper examines the disadvantages of this approach and introduces the optimal scaling method as a remedy. The new scheme attempts to restore the continuity property of the measurements as well as provide estimates for most of the missing responses. Application of the new scheme to the Hong Kong QOL data illustrates how the scheme works, demonstrates its advantages and shows how the QOL indicators, the global QOL indicator as well as its inherited indicators, can be constructed from series of principal component analyses. Factor analysis of the 20 life domain indicators verifies Wan's opinion (1992) that the global sense of well-being can best be captured by two dimensions, namely the personal well-being and the societal well-being. Although previous QOL studies had seldom included perceptions towards various societal conditions to identify life satisfaction in general, our data analysis shows that satisfaction on these conditions do constitute an important component of the global QOL.     

The Lesbian Internalized Homophobia Scale: a rational/theoretical approach

This article reports the development and psychometric properties of a new scale that measures internalized homophobia in lesbians: the Lesbian Internalized Homophobia Scale (LIHS). This 52-item measure was developed using a rational/theoretical approach of test construction and includes five subscales. Research findings, based on a sample of 303 female participants, supported the reliability and validity of the LIHS in assessing internalized homophobia in lesbians. Implications for research and practice are discussed.     

Modification and simplification of thurstone scaling method,and its demonstration with a crime seriousness assessment

The paper aims to improve the Thurstone scaling method by reducing the workload of data collection and simplifying the procedures of application. It proposes a hierarchical structure for organizing items that are to be scaled. Instead of making paired comparisons, the respondents would be asked to rank the items. The ranks of the items would then be transformed into paired comparisons. Workload of data collection can hence be greatly reduced. As an alternative to Thurstone model, the use of three models, i.e., linear, exponential and information, to compute serious scores is also demonstrated.     

Pay‐Back‐Revenue‐Sharing Contract in Coordinating Supply Chains with Random Yield

We consider coordination issues in supply chains where supplier's production process is subject to random yield losses. For a simple supply chain with a single supplier and retailer facing deterministic demand, a pay back contract which has the retailer paying a discount price for the supplier's excess units can provide the right incentive for the supplier to increase his production size and achieve coordination. Building upon this result, we consider coordination issues for two other supply chains: one with competing retailers, the other with stochastic demand. When retailers compete for both demand and supply, they tend to over‐order. We show that a combination of a pay back and revenue sharing mechanism can coordinate the supply chain, with the pay back mechanism correcting the supplier's under‐producing problem and the revenue sharing mechanism correcting the retailers' over‐ordering problem. When demand is stochastic, we consider a modified pay‐back‐revenue‐sharing contract under which the retailer agrees to not only purchase the supplier's excess output (beyond the retailer's order), but also share with the supplier a portion of the revenue made from the sales of the excess output. We show that this contract, by giving the supplier additional incentives in the form of revenue share, can achieve coordination.     

Transforming Policy Standards to Promote Equity and Developmental Success Among Latinx Children and Youth

The main goal of this social policy report is to propose a holistic approach for promoting developmental success among Latinx children and youth. This report highlights the need to 1) redefine success and 2) account for intersectional inequalities. First, the current demographic landscape of Latinx students is presented to showcase the variability in experiences among Latinx children and youth. We review past policies (across the last two and current U.S. Administrations and within the state of California), educational programs (e.g., McNair scholars' program, AVID), and theoretical frameworks (within developmental and sociocultural disciplines). Next, we introduce a nuanced holistic approach for promoting Latinx children and youth's developmental success, underscoring the integration of factors within the sociocultural, family, and individual domains. Finally, this report provides accessible recommendations for policymakers, researchers, and practitioners to effectively promote equity and developmental success among diverse groups of Latinx children and youth.     

Developments in and prospects for external debt position and burden of developing countries: The case of Korea

The delay of strong economic recovery by industrialized nations, slowed world export growth, and higher interest rates have worsened the financial situation of a number of developing countries which have relied on external borrowings to sustain current account deficits and protect economic development. Recently, well-publicized concerns over the ability to these countries to repay their considerable debt burden have been raised. To shed light on these concerns, the paper focuses on Korea—one of the heavier debt-holding countries. It describes the process through which Korea has acquired its external debt over the past decade, assesses the trends in its debt burden, and presents prospects for the period 1982–1986. Using the Korean experience, the paper shows that the most common indicators used for evaluating foreign debt burden, such as the long-term service ratio, need to be supplemented by other measurements. In a world economy characterized by short-term debts with variable interest rates, the paper suggests that an important tool in analyzing the external debt burden should be the short-term debt burden.     

Challenges for grandparent housing programs

The purpose of this article is to explore the current and developing grandparent caregiver housing programs throughout the United States. Telephone interviews were conducted with eight current and proposed sites for grandparent and/or relative caregivers throughout the United States. Housing design, funding sources, referral sources, service provided, and rules and regulations of the housing programs were discussed. Funding, education, and advocacy appeared crucial to helping these families provide safe homes for the children in their care. Recommendations are made for social workers and grandparent caregivers to lobby legislators for increases in funding for programs nationwide to ensure all grandparent families have safe, affordable and accessible housing.     

Majority vote of even and odd experts in a polychotomous choice situation

The performance of majority vote by an odd number of voters in a dichotomous situation is a much-studied subject. In this paper, we study the performance of group consensus in a situation of polychotomous choice. The differences in majority vote behaviour between even and odd numbers of expert panellists are examined, and the effects of adding new members are derived. Unlike the dichotomous model, optimality in the present context may not be uniquely defined, so the probabilities of the consensus being correct or erroneous are both considered as the number of experts is increased.     

Temporary versus Permanent Youth Brain Drain: Economic Implications

Existing high levels of temporary migration between Central and Eastern Europe and the European Union (EU) have highlighted a number of concerns relating to the eastern enlargement of the Union. While much of the debate has focused on the destinations, we use Slovakia as a case study to explore economic implications for the countries of origin of highly skilled migrants. First, the paper examines estimates of the scale of “youth brain migration”, comparing survey‐based and expert‐opinion estimates with our own estimate based on reconciling labour market and educational data. This identifies a substantial loss of graduate workers from the labour force through migration, accounting for a potentially significant proportion of Gross Domestic Product (GDP) growth. Second, we consider whether such migration will constitute “brain drain/overflow” or “brain circulation”: in other words will it be temporary or permanent? In some ways, however, this is a false dichotomy, for there are strong links between initial temporary migration and intended permanent migration, explored here through a survey of the motivations and social networks of returned migrants. Third, we address the ability of national states to intervene to mediate such losses. We generally concur with other commentators on the need for a multi‐scalar and multi‐functional approach, focusing especially on economic development. However, we are pessimistic about the likely speed of economic convergence and, moreover, argue that initial temporary migration (with implications for permanent migration) will continue to be driven by non‐economic goals.
