    This report presents the replication of an MTI study conducted in 2001 by Peter Haas and Richard Werbel. That research, itself a continuation of an earlier project completed in 2000, included an analysis of transportation tax elections in 11 urban areas across the nation and culminated in the identification of 17 community-level factors with potential impact on the success of ballot measures for sales tax increases to fund transportation packages with substantial rail components. Trends observed in these more recent case studies were generally highly consistent with the following findings from the 2001 study. Thus this analysis reaffirms the importance for community consensus amongst the business, elected and environmental communities, and accompanying depth of financial support. Once again, the difficulty of passing an initiative without well-funded, effective use of multimedia was validated, as was the importance of utilizing experienced campaign consultants. Some factors seemed less important in the current study than in 2001, including the effectiveness of presenting a multimodal package, the perception of benefits of a package being distributed throughout the voting district, the experience gained in recent transit elections, and the credibility of the transit agency. Finally, this compilation includes an exploration of “rebound” elections – those instances in which a failed measure is quickly followed by a successful one – and the factors that seem linked to achieving success in such instances

    Estimating Workforce Development Needs for High-Speed Rail in California, Research Report 11-16

    This study provides an assessment of the job creation and attendant education and training needs associated with the creation of the California High-Speed Rail (CHSR) network, scheduled to begin construction in September 2012. Given the high profile of national and state commitment to the project, a comprehensive analysis that discusses the education, training, and related needs created during the build out of the CHSR network is necessary. This needs assessment is achieved by means of: 1) analyzing current high-speed rail specific challenges pertaining to 220mph trains; 2) using a more accurate and robust “bottom-up” approach to estimate the labor, education, skills, and knowledge needed to complete the CHSR network; and 3) assessing the current capacity of railroad-specific training and education in the state of California and the nation. Through these analyses, the study identifies the magnitude and attributes of the workforce development needs and challenges that lie ahead for California. The results of this research offer new insight into the training and education levels likely to be needed for the emergent high-speed rail workforce, including which types of workers and professionals are needed over the life of the project (by project phase), and their anticipated educational level. Results indicates that although the education attained by the design engineers of the system signifies the most advanced levels of education in the workforce, this group is comparatively small over the life of the project. Secondly, this report identifies vast training needs for the construction workforce and higher education needs for a managerial construction workforce. Finally, the report identifies an extremely limited existing capacity for training and educating the high-speed rail workforce in both California and in the U.S. generally

    Walking the Line: Renaissance and Reformation Societal Views on Lesbians and Lesbianism

    Despite being popular eras, research concerning the European Renaissance and Reformation often push minorities to the side, instead focusing on the men in power. This paper discusses the social freedoms and restrictions on women loving women from the fourteenth to eighteenth centuries in England and mainland Europe, and the changes, or lack thereof, that occurred as the Renaissance transitioned into the Reformation, including examples of religious and legal codes, art and literature, and the lives of women from the time. The author used primary source books and documents along with secondary research articles, books and journals to support her case

    Evaluation of participants' experiences with a non-restrictive minimally-structured lifestyle intervention. CHERE Working Paper 2010/11

    While there is increasing evidence that group-based lifestyle-focussed interventions may provide more realistic, effective and cost-effective alternatives to intensive, individualised dietary counselling and exercise training, relatively little is known about individuals? preferences for and perceptions of these programs. This paper reports the results of qualitative interviews conducted with participants of a lifestyle intervention trial (Shape up for Life? (SufL) aimed to improve body composition and metabolic health through long-term non-restrictive behaviour modification. Purposive sampling was used to identify 22 participants who participated in detailed interviews regarding their expectations of the intervention, perceptions of benefits and their experience post-intervention and capacity to maintain the lifestyle changes. The results indicate that in general participants are focussed on weight loss as a goal, even when the intervention offered and provided other benefits such as improved fitness and body shape and composition. The individuals who benefited most from the intervention typically had lower baseline knowledge about dietary and exercise guidelines. While the relatively non-restrictive nature of SufL provided flexibility for participants, many participants perceived that a more structured program may have assisted in achieving weight loss goals.Obesity, lifestyle intervention, weight loss, metabolic syndrome

    Reirradiation practices for children with diffuse intrinsic pontine glioma

    Get PDF
    Background: Diffuse intrinsic pontine gliomas (DIPGs) are a leading cause of brain tumor deaths in children. Current standard of care includes focal radiation therapy (RT). Despite clinical improvement in most patients, the effect is temporary and median survival is less than 1 year. The use and benefit of reirradiation have been reported in progressive DIPG, yet standardized approaches are lacking. We conducted a survey to assess reirradiation practices for DIPG in North America. Methods: A 14-question REDCap survey was disseminated to 396 North American physicians who care for children with CNS tumors. Results: The response rate was 35%. Participants included radiation-oncologists (63%; 85/135) and pediatric oncologists/neuro-oncologists (37%; 50/135). Most physicians (62%) treated 1 to 5 DIPG patients per year, with 10% treating more than 10 patients per year. Reirradiation was considered a treatment option by 88% of respondents. Progressive disease and worsening clinical status were the most common reasons to consider reirradiation. The majority (84%) surveyed considered reirradiation a minimum of 6 months following initial RT. Doses varied, with median total dose of 2400 cGy (range, 1200-6000 cGy) and fraction size of 200 cGy (range, 100-900 cGy). Concurrent use of systemic agents with reirradiation was considered in 46%, including targeted agents (37%), biologics (36%), or immunotherapy (25%). One-time reirradiation was the most common practice (71%). Conclusion: Although the vast majority of physicians consider reirradiation as a treatment for DIPG, total doses and fractionation varied. Further clinical trials are needed to determine the optimal radiation dose and fractionation for reirradiation in children with progressive DIPG

    Depression and mortality: Artifact of measurement and analysis?

    Background Previous research demonstrates various associations between depression, cardiovascular disease (CVD) incidence and mortality, possibly as a result of the different methodologies used to measure depression and analyse relationships. This analysis investigated the association between depression, CVD incidence (CVDI) and mortality from CVD (MCVD), smoking related conditions (MSRC), and all causes (MALL), in a sample data set, where depression was measured using items from a validated questionnaire and using items derived from the factor analysis of a larger questionnaire, and analyses were conducted based on continuous data and grouped data. Methods Data from the PRIME Study (N=9798 men) on depression and 10-year CVD incidence and mortality were analysed using Cox proportional hazards models. Results Using continuous data, both measures of depression resulted in the emergence of positive associations between depression and mortality (MCVD, MSRC, MALL). Using grouped data, however, associations between a validated measure of depression and MCVD, and between a measure of depression derived from factor analysis and all measures of mortality were lost. Limitations Low levels of depression, low numbers of individuals with high depression and low numbers of outcome events may limit these analyses, but levels are usual for the population studied. Conclusions These data demonstrate a possible association between depression and mortality but detecting this association is dependent on the measurement used and method of analysis. Different findings based on methodology present clear problems for the elucidation and determination of relationships. The differences here argue for the use of validated scales where possible and suggest against over-reduction via factor analysis and grouping.
