Scanner Data and the Treatment of Quality Change in Nonrevisable Price Indexes

The recently developed rolling year GEKS procedure makes maximum use of all matches in the data to construct nonrevisable price indexes that are approximately free from chain drift. A potential weakness is that unmatched items are ignored. In this article we use imputation Törnqvist price indexes as inputs into the rolling year GEKS procedure. These indexes account for quality changes by imputing the “missing prices” associated with new and disappearing items. Three imputation methods are discussed. The first method makes explicit imputations using a hedonic regression model which is estimated for each time period. The other two methods make implicit imputations; they are based on time dummy hedonic and time-product dummy regression models and are estimated on bilateral pooled data. We present empirical evidence for New Zealand from scanner data on eight consumer electronics products and find that accounting for quality change can make a substantial difference.     

Ethical Numbers: Ethics Training in U.S. Graduate Statistics Programs, 2013–2014

As important members of research teams, statisticians bear an ethical responsibility to analyze, interpret, and report data honestly and objectively. One way of reinforcing ethical responsibilities is through required courses covering a variety of ethics-related topics at the graduate level. We assessed ethics requirements for graduate-level statistics training programs in the United States for the 2013–2014 academic year using the websites of 88 universities, examining 103 biostatistics programs, and 136 statistics degree programs. We categorized programs’ ethics training requirements as required or not required. Thirty-one (35.1%) universities required an ethics course for at least some degree students. Sixty-two (25.5%) degree programs required an ethics course for at least some students. The majority (77.4%) of required courses were worth 0 or 1 credit. Of the 177 programs without an ethics requirement, 19 (10.7%) listed an ethics elective. Although a single ethics course is insufficient for instilling an ethical approach to science, degree programs that model expectations through coursework point to the value of ethics in science. More training programs should prepare statisticians to consider the ethical dimensions of their work through required coursework. Supplementary materials for this article are available online.     

College Student Smokers' Cognitive Appraisal of High-Risk Activities

Abstract

Objective: Students who smoke are more likely to engage in risky behaviors such as binge drinking and unprotected sex (Schnieder and Morris, Environ Behav. 1999; 23:575–591). The goals of the present study were to determine whether smokers assess these behaviors as lower risk than nonsmokers, and if smoking rate influences risk perceptions. Methods: Participants were 303 college students. Cognitive Appraisal of Risky Activities (Fromme et al., Cognit Ther Res. 1997; 21:421–442) and smoking were assessed August–November, 2006. Results: Smokers reported significantly less risk, more benefit, and more involvement in risky behaviors than nonsmokers (p < .01). In hierarchical linear regression, risk perceptions moderated the association between smoking and (a) expected benefit from risky sexual behaviors (β = ?1.121, p < .05); and (b) expected involvement with illicit drugs (β = ?.313, p < .01). Conclusions: College smokers’ assessment of high-risk behaviors influenced their intended involvement. Risk perception change may therefore alter their involvement in high-risk behaviors.     

The World’s Mightiest Naval Station

The Korean War is often given a cursory glance, if that, in U.S. foreign relations today. This article provides all the information necessary to conduct a role-play in one class period to help students understand the events of the war. Introductory and follow-up questions are also included to stimulate discussion and to connect the events of a war over half a century ago to the events of today.     

Our American Heritage

This article offers a contextual analysis of contemporary immigration issues impacting the institutions in the United States, in particular the school. It discusses the importance of addressing this theme in the classroom and presents its curricular value in the elementary and middle school social studies and interdisciplinary curricula. Using a picture book thematic text set on the topic of immigration allows for multiple curricular venues and connections through which teachers can address the complexities of immigration. Included is a recommended thematic text set annotated bibliography of twenty-three picture books of different reading levels about historical and mostly contemporary immigration issues. This annotated bibliography is a valuable curriculum resource for teachers because it supports the social studies’ curriculum and its integration with other subject areas, such as language arts and the arts. Each book's bibliographical information offers teachers suggested teaching focal themes and content knowledge, target processes of inquiry and discussion, and attitudinal dispositions that can be fostered.     

Becoming a Social Worker: Chris' Account

Chris Murray, a young African-American male, admitted on a scholarship to a social work masters program, reflexively explores his negotiation of difference in dialogue with an Australian female social work educator twice his age. Standpoint theory and the concept of intersectionality are used to frame Chris' experiences at a private northeast US university after achieving an undergraduate degree in his southern home state. His initial access to university came through military service. Chris was interviewed by the author as part of her international study project examining social work students' experience of diversity in the classroom. The open-ended interview was designed to allow self-identity of difference. Chris ethnographically recounts to a stranger a subjectivity statement of who he is in relation to studying social work. Chris' story works the hyphen between the binary of subjectivity and objectivity through the particulars of his personal history and world-view and his expectation that I as a social work educator share his seeking of social justice. His detailing of what moved him to become a social worker and contextual complexities negotiated along the way connect to wider discourses on how agency and structure play out in lived experience in seeking social justice.     

Child migration

It is considered important to construct models of social work in particular settings in order to refine practice and to enhance the power position of practitioners in identifying appropriate roles and tasks in relation to other professions. The purpose of this paper is to contribute to the accumulation of data about social work in association with legal aid, leading to the formulation of a model or practice in such a setting. Data is presented here in relation to three groups of personnel participating in the Caxton Street Legal Service in Brisbane: lawyer perceptions of social work roles and types of problems appropriately dealt with by social workers, similar perceptions of a group of social workers forming a roster of volunteers, and the actual roles and activities of three social work students placed at C.S.L.S. during 1980. Of major interest is the predominantly casework conciliatory nature of role perceptions and activities in the agency's declared policy. Analysis suggests that this situation is explicable partly in terms of political expediency in relation to funding aims, and partly in terms of the voluntary, part-time and fragmentary nature of the service. The need for further clarification of a practice model remains, however, if social workers are to extend their role in legal aid.
