    Potential performance for Pb-Pb, p-Pb and p-p collisions in a future circular collider

    Full text link
    The hadron collider studied in the Future Circular Collider (FCC) project could operate with protons and lead ions in similar operation modes as the LHC. In this paper the potential performances in lead-lead, proton-lead and proton-proton collisions are investigated. Based on average lattice parameters, the strengths of intra-beam scattering and radiation damping are evaluated and their effect on the beam and luminosity evolution is presented. Estimates for the integrated luminosity per fill and per run are given, depending on the turnaround time. Moreover, the beam-beam tune shift and bound free pair production losses in heavy-ion operation are addressed.Comment: Submitted to PRSTA

    This study explored academic underachievement of fourth form boys in male secondary schools within the Auckland area. There were two aspects to this study; firstly, to identify students who are underachieving relative to their abilities and secondly, to explore possible psychological differences between underachievers and non-underachievers. An underachiever for the purpose of this study is a student who is achieving lower grades than expected in accordance with his abilities (McCall, Evahn & Kratzer, 1992). 598 of the 770 students enrolled in the participating schools had the necessary data for regression analyses to identify underachievers. Of the 598 students with valid data, 315 consented to participate in the questionnaire. The sample for this study comprised 315 fourth form boys. A discrepancy model using regression analysis was carried out on the 315 students to identify underachievers within the schools. 82 students were identified as underachievers using this method, which resulted in 13.9% of the sample being defined as underachievers. In addition, a self-report questionnaire was administered to the 770 students. The questionnaire measured six psychological dimensions that have been identified in previous research to be related to academic achievement. The responses of the underachieves and non-underachievers were compared to ascertain whether these two groups differ on the psychological dimensions measured. These psychological constructs measured in the questionnaire included study strategies (cognitive/self-regulation, persistence/effort, and disorganisation), social support, self- efficacy, test anxiety, intrinsic motivation/interest in school subjects, and outcome expectancies. There was a significant mean difference between non-underachievers and underachievers on the disorganisation scale. This finding suggests that underachievers had more disorganised study habits than their non-underachieving comparison group. There were also significant mean differences between underachievers and non-underachievers for intrinsic value in English and science. These findings suggested that underachievers were more intrinsically motivated in English than their non-underachieving comparison group, but less intrinsically motivated in Science

    Understanding Barriers to HPV vaccine uptake in Appalachia

    Every year in seven small counties of Ohio seventy-six people lose their lives to a completely preventable Human Papillomavirus-related cancer. These counties are not random, nor are they an anomaly. All seven are considered to be within the Appalachian region of the United States, which, despite holding a little less than one-tenth of the total population, has the highest cancer mortality rates in the country. The term Appalachia describes the counties surrounding the Appalachian mountain range in the eastern United States. Here, rates of Human Papillomavirus (HPV), vaccine uptake are lower than in other areas of the United States. This study seeks to examine, using the 5 A's of Healthcare Access framework (Affordability, Accessibility, Accommodation, Acceptability, and finally Availability) why, despite there being a viable vaccine, rates of uptake remain low using the seven aforementioned counties as a sample. In using a mixed methods approach, the study integrates existing research from major public databases with the direct input of medical professionals gathered via survey. The professionals were asked for their opinion on the impact each of the Five A's of Healthcare Access have on their patients, using data from 2018-19. Through analyzing their answers, as well as related research, the study hopes to provide important information on HPV-vaccine barriers for further programs to use in order to lower the number of preventable deaths.The Ohio State School of Social WorkNo embargoAcademic Major: Social Wor
