Older Adults Embracing Technology: Leave No One Behind

The goal of this exploratory study, conducted throughout 2005 - 2006, was to examine effective ways to provide both initial computer training and ongoing technical support for elders with little or no computer experience, and to explore whether the accomplishment of acquiring computer skills had an impact on the elders’ quality of life. The computer training and follow-up technical support were provided by student volunteers trained specifically for this study. Following the computer training, all participants were offered 12 weeks of ongoing technical support (phone, email or in person) by the same student tech tutors and additional student volunteers. Questionnaires measuring computer comfort and proficiency were administered pre and post training and again at 6 weeks and 12 weeks after the training. Participants kept logs of their computer use and recorded their goals, successes, and challenges throughout the study. The trained and volunteer tech tutors kept field notes of the elders’ learning, and recorded the nature of the technical help requested by the participants. A number of common themes were revealed in the narrative data of both the elders and the student tech tutors. These were clustered into four categories: social inclusion; the teaching and learning experience; expanding horizons; and expressions of self-efficacy. Specific challenges encountered by tech tutors and participants are presented and innovative teaching strategies are proposed. Findings point to the need for further studies to explore the psychosocial factors that motivate and hinder elder requests for ongoing technical help as well as the need for outreach to convey the unexpected benefits of going online to nonusers. A number of recommendations and implications for policy, education and further research were highlighted by the study

Lung Cancer and Vehicle Exhaust in Trucking Industry Workers

Background: An elevated risk of lung cancer in truck drivers has been attributed to diesel exhaust exposure. Interpretation of these studies specifically implicating diesel exhaust as a carcinogen has been limited because of limited exposure measurements and lack of work records relating job title to exposure-related job duties. Objectives: We established a large retrospective cohort of trucking company workers to assess the association of lung cancer mortality and measures of vehicle exhaust exposure.Methods Work records were obtained for 31,135 male workers employed in the unionized U.S. trucking industry in 1985. We assessed lung cancer mortality through 2000 using the National Death Index, and we used an industrial hygiene review and current exposure measurements to identify jobs associated with current and historical use of diesel-, gas-, and propane-powered vehicles. We indirectly adjusted for cigarette smoking based on an industry survey.Results Adjusting for age and a healthy-worker survivor effect, lung cancer hazard ratios were elevated in workers with jobs associated with regular exposure to vehicle exhaust. Mortality risk increased linearly with years of employment and was similar across job categories despite different current and historical patterns of exhaust-related particulate matter from diesel trucks, city and highway traffic, and loading dock operations. Smoking behavior did not explain variations in lung cancer risk. Conclusions: Trucking industry workers who have had regular exposure to vehicle exhaust from diesel and other types of vehicles on highways, city streets, and loading docks have an elevated risk of lung cancer with increasing years of work.Statistic

Lung Cancer and Elemental Carbon Exposure in Trucking Industry Workers

Background: Diesel exhaust has been considered to be a probable lung carcinogen based on studies of occupationally exposed workers. Efforts to define lung cancer risk in these studies have been limited in part by lack of quantitative exposure estimates. Objective: We conducted a retrospective cohort study to assess lung cancer mortality risk among U.S. trucking industry workers. Elemental carbon (EC) was used as a surrogate of exposure to engine exhaust from diesel vehicles, traffic, and loading dock operations. Methods: Work records were available for 31,135 male workers employed in the unionized U.S. trucking industry in 1985. A statistical model based on a national exposure assessment was used to estimate historical work-related exposures to EC. Lung cancer mortality was ascertained through the year 2000, and associations with cumulative and average EC were estimated using proportional hazards models. Results: Duration of employment was inversely associated with lung cancer risk consistent with a healthy worker survivor effect and a cohort composed of prevalent hires. After adjusting for employment duration, we noted a suggestion of a linear exposure–response relationship. For each 1,000-µg/m3 months of cumulative EC, based on a 5-year exposure lag, the hazard ratio (HR) was 1.07 [95% confidence interval (CI): 0.99, 1.15] with a similar association for a 10-year exposure lag [HR = 1.09 (95% CI: 0.99, 1.20)]. Average exposure was not associated with relative risk. Conclusions: Lung cancer mortality in trucking industry workers increased in association with cumulative exposure to EC after adjusting for negative confounding by employment duration

On Overreaching, or Why Rick Perry May Save the Voting Rights Act but Destroy Affirmative Action

Abstract The State of Texas is presently staking out two positions that are not typically pursued by a single litigant. On the one hand, Texas is seeking the invalidation of the Voting Rights Act, and, on the other, the State is now defending the validity of the expansive race-based affirmative action policy it uses at its flagship university. This Essay presses the claim that Texas has increased the chance it will lose in both Texas v. Holder and Fisher v. University of Texas because it has opted to stake out markedly extreme positions in each. I argue that Texas would be more likely to succeed had it chosen to temper both its actions and claims in the pending cases. As it stands, Texas's assertive stance in Fisher promises to bolster the aversion many Justices already feel towards affirmative action. With regard to the VRA, however, Texas's uncompromising approach to the regime may prove to be the VRA's best defense. As recent redistricting and voter ID decisions suggest, Texas's stance may be provide what is arguably better evidence for why the statute remains necessary than anything proffered by the VRA's many supporters. Indeed, the State's aggressively hostile stance towards the VRA has the potential to destabilize judicial misgivings about the statute, and, if not fully reverse them, postpone their implementation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/98443/1/elj%2E2012%2E1147.pd

Sustainability as corporate culture of a brand for superior performance

This paper reviews the literature to understand the ability of sustainable green initiatives when practiced as a corporate culture to individually create new opportunities for operations, management and marketing. According to current research, business opportunities exclusively available to different functions of a firm can drive its performance. The role of marketing in the achievement of superior performance by virtue of sustainability practices is also explained by the existing literature. Branding literature, however, fails to explain the influence of a brand on sustainability-driven opportunities available to a firm for superior performance. The objective of this study is to explore if a brand can strengthen the ability of sustainability-based green initiatives of managers to drive opportunities available to a firm for superior performance. A conceptual framework grounded in the triple bottom line theory is presented based on the assumption that brand as a stimulating factor can accelerate the conversion of opportunities available to a business into superior performance. Academic and managerial perspectives have been used to draw upon the implications of the model. Both practitioners and academic researchers will benefit from future research on this topic

Evaluation of longitudinal 12 and 24 month cognitive outcomes in premanifest and early Huntington's disease

BACKGROUND: Deterioration of cognitive functioning is a debilitating symptom in many neurodegenerative diseases, such as Huntington's disease (HD). To date, there are no effective treatments for the cognitive problems associated with HD. Cognitive assessment outcomes will have a central role in the efforts to develop treatments to delay onset or slow the progression of the disease. The TRACK-HD study was designed to build a rational basis for the selection of cognitive outcomes for HD clinical trials. METHODS: There were a total of 349 participants, including controls (n=116), premanifest HD (n=117) and early HD (n=116). A standardised cognitive assessment battery (including nine cognitive tests comprising 12 outcome measures) was administered at baseline, and at 12 and 24 months, and consisted of a combination of paper and pencil and computerised tasks selected to be sensitive to cortical-striatal damage or HD. Each cognitive outcome was analysed separately using a generalised least squares regression model. Results are expressed as effect sizes to permit comparisons between tasks. RESULTS: 10 of the 12 cognitive outcomes showed evidence of deterioration in the early HD group, relative to controls, over 24 months, with greatest sensitivity in Symbol Digit, Circle Tracing direct and indirect, and Stroop word reading. In contrast, there was very little evidence of deterioration in the premanifest HD group relative to controls. CONCLUSIONS: The findings describe tests that are sensitive to longitudinal cognitive change in HD and elucidate important considerations for selecting cognitive outcomes for clinical trials of compounds aimed at ameliorating cognitive decline in HD
