Development of a lateral mobility task to identify individuals at risk for mobility disability and functional decline

Lateral mobility is integral to many activities of daily living involving transfer from one position to another. The objective of this study was to develop and evaluate the validity and test-retest reliability of a lateral-mobility (LATMOB) task for older adults. Measurements of lateral mobility, balance, and strength and self-reported and performance-based physical functioning were obtained in 63 women and 77 men > or = 50 years of age. The LATMOB task was significantly correlated with age, knee-extensor strength, grip strength, functional reach, and one-leg-stance time. Test-retest reliability of the task was excellent. The LATMOB task was highly correlated with the car task. Balance was significantly correlated with time to get into and out of a car and performance on the LATMOB task. The LATMOB task was significantly correlated with the Short Physical Performance Battery score. The LATMOB task is valid and reliable, but additional work is needed to assess its sensitivity to change and predictive validity.     

Response distortion in adolescents who smoke: a pilot study

A wide range of data are obtained with self-report. Information obtained from persons using substances is generally reliable and valid, however, many studies show that some proportion of self-reports regarding substance use are inaccurate. This study examines self-reported response distortion in adolescents who received a brief intervention to reduce their smoking. Findings indicate that age and ethnicity of respondent may influence reported response distortion. Factors that appear to influence under- and over-reporting include social desirability and fear of repercussion. Response distortion does not appear to affect rated usefulness of the intervention, nor does intervention type appear to influence whether respondents thought the researcher wanted them to report less use. Results point to the need for further research regarding adolescents and response distortion.     

Ethnic Group and Social Class Differences in College Students' Career Development

The purpose of this investigation was to examine ethnic group and social class differences in 401 college students' career development. Assessments of career development included career decision-making attitudes, vocational congruence, and career decision-making skills. Statistical analyses did not reveal any social class differences in career development. Ethnic group differences, however, were observed, including significant differences in career decision-making attitudes and vocational congruence. Findings suggest that current theories of career development are lacking in their application to today's ethnically diverse college population. Future directions for cross-cultural career development research and implications for career counselors are discussed.     

Factor structure of quality of life: The Lehman interview

This study of 67 chronically mentally ill outpatients with psychotic disorders examined subjective quality of life scores from Lehman's Quality of Life (QOL) interview. Factor analyses identified ‘Affiliative’ and ‘Instrumental’ dimensions which accounted for 67% of the variance in subjective satisfaction ratings. The results suggest a model in which instrumental and affiliative needs comprise significant portions of subjective life satisfaction and that global QOL satisfaction is related more to instrumental than affiliative needs. These findings further clarify the concept of life satisfaction in this population of severely mentally ill individuals and suggest modifications in how quality of life information is evaluated.     

Ecosystem processes along an urban-to-rural gradient

In order to understand the effect of urban development on the functioning of forest ecosystems, during the past decade we have been studying red oak stands located on similar soil along an urban-rural gradient running from New York City ro rural Litchfield County, Connecticut. This paper summarizes the results of this work. Field measurements, controlled laboratory experiments, and reciprocal transplants documented soil pollution, soil hydrophobicity, litter decomposition rates, total soil carbon, potential nitrogen mineralization, nitrification, fungal biomass, and earthworm populations in forests along the 140 × 20 km study transect. The results revealed a complex urban-rural environmental gradient. The urban forests exhibit unique ecosystem structure and function in relation to the suburban and rural forest stands these are likely linked to stresses of the urban environment such as air pollution, which has also resulted in elevated levels of heavy metals in the soil, the positive effects of the heat island phenomenon, and the presence of earthworms. The data suggest a working model to guide mechanistic work on the ecology of forests along urban-to-rural gradients, and for comparison of different metropolitan areas.     

A simple below-ground marker for permanent plots in urban and suburban environments

There is a need to establish permanent vegetation plots to study vegetation dynamics in urban and suburban landscapes. The construction and installation of a simple and inexpensive below-ground marker suitable for areas with high levels of human activity are described. These markers have been used effectively over the past decade to establish permanent plots in forests in New York City. This revised version was published online in July 2006 with corrections to the Cover Date.     

The Iowa Gambling Treatment Program: Treatment Outcomes for a Follow-up Sample

The Iowa Gambling Treatment Program (IGTP) amassed participant data for gamblers and concerned others of gamblers over 4 years (1997–2001). Data collection opportunities included: (1) crisis contacts, (2) placement screening, (3) admission, (4) treatment services, (5) discharge, and (6) follow-up. Among followed gamblers, 74% of treatment completers, 49% of substantial treatment completers, and 36% of dropouts and referrals were abstaining from gambling at 6-month follow-up. The reduction in dollars lost to gambling was similar; 85% of treatment completers, 88% of substantial treatment completers, and 65% of others reduced their dollars lost per week. Although more extensive follow-up efforts are needed to properly evaluate the effectiveness of the IGTP, these results suggest that the IGTP shows promise.     

Does Class Consciousness Exist in Rural Communities? The Impact of Restructuring and Plant Shutdowns in Rural Canada1

Abstract This paper examines qualitative data on class consciousness derived from a study of corporate restructuring and the impacts of layoffs in rural Ontario communities. In particular, the study examines how the rural environment might impinge on the development of class consciousness among the workers there in the context of severe economic stress brought on by plant shutdowns. It is argued that an ideology specific to a farm and small town environment plays a significant role in shaping their response to crisis. The more standard predictors of class consciousness such as age, gender, past union membership, and employment status are also considered. The paper aims to deepen our understanding of the seemingly contradictory belief structures of working class people.     

Designing for a Response Transformation Parameter

We investigate D -optimum designs for experiments in which a linear model holds after an unknown power transformation of the univariate response variable. This is a departure from standard D -optimal design in which an appropriate scale for the response is assumed known before data collection. The design problem that we formulate is intrinsically non-linear, requiring characterization of likely parameter values. Several applications are presented to illustrate the importance of recognizing the role of response transformations at the design stage.
