A Mixed-Methods Approach to Refining and Measuring the Construct of Positive Risk-Taking in Adolescence

Adolescence is a peak period for risk-taking, but research has largely overlooked positive manifestations of adolescent risk-taking due to ambiguity regarding operationalization and measurement of positive risk-taking. We address this limitation using a mixed-methods approach. We elicited free responses from contemporary college students (N = 74, M_age = 20.1 years) describing a time they took a risk. Qualitative analysis informed the construction of a self-report positive risk-taking scale, which was administered to a population-based sample of adolescents (N = 1,249, M_age = 16 years) for quantitative validation and examination of associations with normative and impulsive personality. Sensation seeking predicted negative and positive risk-taking, whereas extraversion and openness were predominantly related to positive risk-taking. Results provide promising evidence for a valid measure of adolescents' engagement in positive risks.     

The Association Between Same-Sex Romantic Attractions and Relationships and Running Away Among a Nationally Representative Sample of Adolescents

Sexual minorities are overrepresented among the runaway population, and sexual minority runaways are at greater risk for adverse health outcomes than their heterosexual peers. Our knowledge of this vulnerable population has been restricted by methodological limitations of existing studies. This study used a nationally representative sample of U.S. adolescents to explore the association between same-sex romantic attractions and relationships and run away behavior over a 2 year period. Results indicated that although the association between sexual orientation and running away appears to be partially attenuated by other risk factors for running away, there remains a significant positive association between same-sex romantic attractions and running away. Furthermore, youth with no romantic or sexual relationships were significantly less likely to report running away compared to youth with only opposite-sex relationships. These associations remained significant even after controlling for other risk factors.     

Korean and American Children's Concepts of Adult and Peer Authority

The primary purpose of this research was to examine Korean children's concepts of authority. Children's judgments about commands of persons with varying age, social position, and knowledge were assessed. 48 subjects from the first, third, and fifth grades were presented with portrayals of persons giving children commands regarding two types of events: fighting and a game rule dispute. Subjects evaluated the legitimacy of commands and chose between different persons giving opposing commands. With regard to a command to stop fighting, subjects accepted the legitimacy of adult and peer authorities, as well as an adult without a position of authority. Subjects rejected commands that failed to prevent harm even when given by an adult authority. With regard to a game rule dispute, subjects most heavily weighted knowledge in evaluating the authority commands. The findings show that Korean children do not have a unitary orientation to adult authority, and have implications for an understanding of individuals' conceptions in the context of a cultural ideology emphasizing reverence for authority. A second study, with a group of fifth graders from the United States, was conducted to determine how the game event task or cultural influences accounted for some differences between previous findings in the U.S. and the findings with the Korean children. The second study showed that whereas the U.S. children mainly respond in ways similar to the Korean children, the U.S. children gave more priority to pragmatic considerations; the Korean children gave more priority to the attribute of the authority's knowledge.     

A note on the information content of a consistent pairwise comparison judgment matrix of an AHP decision maker

A decision maker using the Analytic Hierarchy Process (AHP) could be consistent, and still provide no information in the resulting vector of priorities. An extreme example would be a pairwise comparison judgment matrix filled with 1s which is totally consistent under the various definitions of consistency, but has provided no information about the prioritization of alternatives resulting from the decision maker's judgments. In this paper, the quality of a consistent decision maker's judgments using the Analytic Hierarchy Process is placed in the context of the entropy of the resulting vector of priorities. Indeed, it is the purpose of this paper to provide a formal definition of this notion ofentropy of a priority vector, and to provide a framework for a quantitative measurement of the information content of consistent pairwise comparison judgment matrices of a decision maker who is using the Analytic Hierarchy Process. We will prove that the entropy of the vector of priorities for consistent matrices follows a normal distribution and discuss some general considerations of this result.     

From Interviewers to Friendly Visitors: Bridging Research and Practice to Meet the Needs of Low-Income Latino Seniors

This article describes a community-based participatory research (CBPR) effort conducted in a low-income, predominantly Latino community, which bridged traditionally-separate domains of practice and research by engaging neighborhood residents in a collaborative capacity-enhancement process for meeting the needs of vulnerable elderly residents. What began as a simple needs assessment to facilitate program development became a mechanism for engaging neighborhood residents in a collaborative social capital development process. The article describes the origins of this community-based effort, its consumer-led transformation from traditional needs assessment to service provision, resulting benefits and challenges, and implications for meeting the needs of vulnerable populations.     

Performance Metric Portfolios: A Framework and Empirical Analysis

The widespread adoption of supply chain management principles suggests that managers recognize the importance of evaluating operational decisions holistically. However, it is often difficult to link specific operational practices to strategic level outcomes and in turn to corporate financial results. This presents problems for both managers and academic researchers attempting to justify the often high cost of operational improvement initiatives in terms of objective accounting metrics. This study provides evidence that it is possible to demonstrate linkages between carefully chosen portfolios of tactical, strategic, and financial metrics. Survey data from 118 manufacturers are used to evaluate hypotheses linking multilevel metrics of performance across three well‐established strategic foci. We present portfolios of metrics drawn from the literature and from the Supply Chain Counciľs supply‐chain operations reference model and related design and customer chain models. Our analysis suggests that metric portfolios in which tactical metrics are designed to match strategic‐level metrics, based on alignment with a specific strategic focus, provide clearer mechanisms for understanding performance linkages.     

Data sources and estimates of charitable giving in Britain

This paper describes how estimates of individual charitable giving are derived from two major continuous surveys: the Family Expenditure Survey and the Individual Giving Survey. It explores the reasons for and the significance of the differences between the two estimates. Conclusions are drawn on the relative merits and demerits of the two survey datasets, and the circumstances in which it might be appropriate to use each of them.
