Getting Back On-Track or Going Off the Rails? An Assessment of Ownership and Organisational Reform of Railways in Western Europe

This paper reports on work undertaken for the European Commission (EC) between 1996 and 1999. It is shown that despite reforms initiated by the EC Directive 91/440, the performance of 17 state owned western European rail operators is poor. Work using non-parametric index numbers indicates only modest productivity growth and mixed financial and commercial performance. Work using cost functions indicates that many railways appear to be of the wrong size and the wrong density to minimise costs. Work using demand functions indicates that there may be substantial scope for pricing up and for reconfiguring service levels. Modelling of cross border flows suggests that international services require increases in service levels and quality. It is argued that Europe s railways are in need of radical reform. A first phase of reform would build on the process already initiated by the EC and involve separate infrastructure authorities, continued commercialisation and privatisation of train operations, creation of rolling stock leasing companies, development of transparent infrastructure access and pricing, the promotion of off-track competition and of coach deregulation. However, it is possible that this first phase of reforms may not be sufficient to achieve the desired results. It is therefore likely that a second phase of reforms will be required including horizontal separation and re-agglomeration of train operations, vertical re-integration and network re-configuration. The scope for off-track competition for vertically integrated concessions might be considered in this second phase.Institute of Transport and Logistics Studies. Faculty of Economics and Business.

Professional Baseball Athletic Trainers\u27 Perceptions of Preparation for Job-Specific Duties

Context The extent to which individuals are prepared completely for work in a particular athletic training setting (eg, professional sports, college, high school) is unknown. This issue is critical today, and findings in this area have implications for athletic training education policy and employers. Objective To determine the perceptions of preparation for work-specific tasks by professional baseball athletic trainers (PBATs). We also wanted to determine whether various preparation experiences interact with perceived skills. Design Cross-sectional study. Setting Online survey administered via SurveyMonkey. Patients or Other Participants Two hundred seventy-five PBATs. Intervention(s) The PBATs reported their levels of preparation before employment in their positions and their current skills in each of the 8 work task domains: evaluation of elbow injuries; evaluation of shoulder injuries; evaluation of general injuries; acute care; injury prevention; treatment, rehabilitation, and reconditioning; organization and administration; and non–athletic-training tasks. Main Outcome Measure(s) Nine repeated-measures analyses of covariance were performed with each perception of preparation (retrospective, current) as a within-subject factor. Preparation experiences were included as between-subjects factors, and number of years working in baseball was the covariate. Results Subscale reliabilities were calculated and found to be between 0.79 and 0.97. A total of 180 PBATs (65%) completed the survey. The backgrounds and routes by which PBATs gained employment in the professional baseball setting varied. Individuals who completed professional baseball internships, had previous work experience, and immediately entered the professional baseball setting after graduation had noted differences in their perceptions of preparation for work tasks. The PBATs indicated they were substantially underprepared for tasks in the organization and administration and non–athletic-training task domains. Conclusions The organizational socialization process is complex, and no 1 experience appears to completely prepare an individual for work in the professional baseball setting. </jats:sec

The demand for public transport: The effects of fares, quality of service, income and car ownership

This paper reports on key findings from a collaborative study whose objective was to produce an up-to-date guidance manual on the factors affecting the demand for public transport for use by public transport operators and planning authorities, and for academics and other researchers. Whilst a wide range of factors was examined in the study, the paper concentrates on the findings regarding the influence of fares, quality of service and income and car ownership. The results are a distillation and synthesis of identified published and unpublished information on the factors affecting public transport demand. The context is principally that of urban surface transport in Great Britain, but extensive use was made in the study of international sources and examples

Supervisors’ ratings of psychology trainees’ competence in field settings are a critical component of training assessment. There has been little systematic research regarding the validity of these assessments, but the available evidence suggests we have a problem! Supervisors’ judgments may be affected by systemic biases that pose a serious threat to assessment credibility. The current study is part of a research collaboration among six universities that endeavors to develop and evaluate a new method—the use of vignettes—against outcomes derived from a conventional rating scale. Individual vignettes were designed and subjected to a rigorous process of peer-review and revisions, before final vignettes were assigned calibration scores by a group of experts. A catalogue of vignettes (n = 41) that represent various domains of competence across several developmental stages was compiled. University and field supervisors used the conventional rating scale and the vignette-matching procedure (VMP) to evaluate competencies at end-placement. Data from a pilot (n = 20) and a follow-up study (n = 57) suggest that compared with a conventional rating scale, the VMP reduced leniency and halo biases. The VMP has the potential to improve outcomes of competency assessments in field placements and merits further research and development

CD1b Tetramers Bind αβ\alpha \beta T Cell Receptors to Identify a Mycobacterial Glycolipid-Reactive T Cell Repertoire in Humans

Microbial lipids activate T cells by binding directly to CD1 and T cell receptors (TCRs) or by indirect effects on antigen-presenting cells involving induction of lipid autoantigens, CD1 transcription, or cytokine release. To distinguish among direct and indirect mechanisms, we developed fluorescent human CD1b tetramers and measured T cell staining. CD1b tetramer staining of T cells requires glucose monomycolate (GMM) antigens, is specific for TCR structure, and is blocked by a recombinant clonotypic TCR comprised of TRAV17 and TRBV4-1, proving that CD1b-glycolipid complexes bind the TCR. GMM-loaded tetramers brightly stain a small subpopulation of blood-derived cells from humans infected with Mycobacterium tuberculosis, providing direct detection of a CD1b-reactive T cell repertoire. Polyclonal T cells from patients sorted with tetramers are activated by GMM antigens presented by CD1b. Whereas prior studies emphasized CD8$^+$ and CD4$^-$CD8$^-$ CD1b-restricted clones, CD1b tetramer-based studies show that nearly all cells express the CD4 co-receptor. These findings prove a cognate mechanism whereby CD1b-glycolipid complexes bind to TCRs. CD1b tetramers detect a natural CD1b-restricted T cell repertoire ex vivo with unexpected features, opening a new investigative path to study the human CD1 system

Bicycle Friendly Community Assessment Spring 2015

Completed by Cal Poly, San Luis Obispo City & Regional Planning students enrolled in a bicycle and pedestrian planning course (CRP 425), under the direction of Dr. William Riggs this report was designed to gather data in advance of the City of San Luis Obispo\u27s application to be a Bicycle Friendly Community.
