The Constructivist Résumé: Promoting the Career Adaptability of Graduate Students in Counseling Programs

The authors present the constructivist résumé, an original approach developed to promote professional identity development and career adaptability (i.e., concern, curiosity, confidence, and control) in students completing graduate‐level counselor training programs. The authors discuss underlying theories, including Super's (1990; Super, Savickas, & Super, 1996) life span, life space theory and Peavy's (1998) SocioDynamic Counseling Model, and their applications to career counseling. They also provide a detailed case illustration, make practical recommendations, and note the advantages and limitations of the approach.     

Self-touching and attentional processes: The role of task difficulty,selection stage,and sex differences

Lateral and bilateral self-touching movements were studied in a group of men and women performing a series of attentional tasks. In all tasks, subjects were instructed to selectively attend to, and shadow (i.e., repeat outloud), one of two passages that were presented simultaneously through earphones. Loudness, voice quality, or thematic content determined which passage had to be selected and shadowed. Performance was significantly better when shadowing on the basis of loudness or voice quality (an earlier, easier selection) than when following content (a more difficult selection that occurs at a later stage in the information processing continuum). However, self-touching rates during performance were not simply a function of task difficulty but seemed to depend on the processing stage at which selection occurred as well as on the type of selection involved. Strong, significant associations emerged between lateral self-touching and performance measures in most of the tasks for the women but in only one task for the men. The sample size on which these correlations are based is small and, hence, these findings must be interpreted with caution. However, in the light of previous findings on sex differences with these tasks, the present results suggest that lateral movements may serve different functions in men and women.We are grateful to Dr. Norbert Freedman, Director of the Unit at which this work was carried out, for his encouragement and support during all phases of this project, and to Dr. Marshall Bush for generously making available to us his selective listening tasks. Some findings reported in this paper were included in the second author's master's thesis at New York University, Department of Psychology.     

A Case Study on the Informational Efficiency of Markets: The Market for Horse Racing in Australia

This paper describes a study of the informational efficiency of the thoroughbred horse racing market in Australia. It is based on the theory of stock market efficiency which explains the process by which information becomes reflected in share prices. In this paper, the theory is applied to the thoroughbred horse racing market to determine the predictive accuracy of alternative informative sources. The results obtained from the study are consistent with the underlying theory:(i) aggregated information (as reflected in a consensus of opinions) is a more accurate prediction of success than less information (as reflected in individual opinions), and;(ii) the most recent information (as reflected in race-time betting odds, known as starting prices) has greater predictive ability than less recent information (as reflected in an earlier consensus of opinions).The study examines predictive accuracy in a gambling context, but does not consider the profitability of alternative prediction processes.     

Expert and Layperson Perceptions of Ecosystem Risk

This research examines and compares perceptions held by laypeople and ecologists about risks to ecosystems, particularly risk from global climate change (GCC). A survey elicited perceptions of 31 risk characteristics for 13 GCC and 12 non-GCC risks to ecosystems. Factor analysis was used to examine the structure of layperson and expert risk perceptions. Both experts and laypeople tend to perceive GCC risks to ecosystems as less avoidable and more acceptable than risks from other causes. Compared to laypeople's perceptions, though, experts perceived GCC risks to have slightly lower impacts, be less avoidable, more acceptable, and less understandable than non-GCC risks to ecosystems. These findings may help guide efforts to communicate with laypeople about ecological risks from climate change.     

Sample size calculation for an agreement study

It is often necessary to compare two measurement methods in medicine and other experimental sciences. This problem covers a broad range of data. Many authors have explored ways of assessing the agreement of two sets of measurements. However, there has been relatively little attention to the problem of determining sample size for designing an agreement study. In this paper, a method using the interval approach for concordance is proposed to calculate sample size in conducting an agreement study. The philosophy behind this is that the concordance is satisfied when no more than the pre‐specified k discordances are found for a reasonable large sample size n since it is much easier to define a discordance pair. The goal here is to find such a reasonable large sample size n. The sample size calculation is based on two rates: the discordance rate and tolerance probability, which in turn can be used to quantify an agreement study. The proposed approach is demonstrated through a real data set. Copyright © 2009 John Wiley & Sons, Ltd.     

Batch sequential designs for computer experiments

Computer models simulating a physical process are used in many areas of science. Due to the complex nature of these codes it is often necessary to approximate the code, which is typically done using a Gaussian process. In many situations the number of code runs available to build the Gaussian process approximation is limited. When the initial design is small or the underlying response surface is complicated this can lead to poor approximations of the code output. In order to improve the fit of the model, sequential design strategies must be employed. In this paper we introduce two simple distance based metrics that can be used to augment an initial design in a batch sequential manner. In addition we propose a sequential updating strategy to an orthogonal array based Latin hypercube sample. We show via various real and simulated examples that the distance metrics and the extension of the orthogonal array based Latin hypercubes work well in practice.     

Growing health disparities for persons who are aging with intellectual and developmental disabilities: the social work linchpin

Similar to the general population, adults with intellectual and developmental disabilities (IDD) are living into their 70s and beyond. Health care disparities have been well-documented for this vulnerable and underserved population. Social workers are often responsible for assessment, coordination of care, and negotiation of needed services for people with IDD. This article explores the challenges facing social workers in meeting the growing health and social needs of aging adults with IDD and their families. Trends in social work practice and gaps in education are discussed as they relate to addressing and reducing current health disparities.     

Estimating discount rates for environmental quality from utility-based choice experiments

We estimate rates of time preference using a utility-based choice experiment administered to a nationally representative sample of 2,914 respondents. For the full sample, the rate of time preference is very high for immediate benefits and drops off substantially thereafter, which is inconsistent with exponential discounting but consistent with hyperbolic discounting. Estimates of the hyperbolic discounting parameter range from 0.48 to 0.61. Visitors to water bodies have low rates of discount but exhibit hyperbolic discounting, whereas those who do not visit have consistently high rates of discount and low valuations of water quality.
