    The principal aim of the work described in this thesis was to discover the extent of the last stage of glaciation in the western part of Highland Perthshire.After preparatory stereoscopic study cf aerial photographs, an area of 450 sq. km in Glen Lyon and southern Rannoch Moor was mapped at the 1:10,560 scale and subsequently another 2250 sq. km were mapped at the 1:63,360 scale. Features of special interest, such as outwash terraces and the lake terraces or 'Parallel Roads' of Loch Tulla, were mapped in greater detail and instrumentally levelled.Particular attention was paid to the character and extent of fresh hummocky drift, described by earlier workers as 'hummocky moraine' and thought to belong to a distinct period of glaciation. From examination of thepatt.ern of this hummocky drift and of the constituent sediments it was concluded that the features are basically kames that are often thickly covered with ablation moraine.Eight major valley systems were studied. They include Glen Garry - Glen Errochty, the Loch Rannoch - Loch Tummel valley, Glen Lyon, the Loch Tay valley, Glen Almond, Glen Artney, Loch Voil - Loch Earn and the Trossachs - Teith valleys, in addition to part of Rannoch Moor. The evidence of fresh glacial deposits in these valleys indicates that a system of glaciers existed in the area during the last stage of glaciation.By discussing the valley systems in turn and regarding each as a case that can be justified independently of the others, it is concluded for three reasons that the last glaciers in each area existed during the same lateglacial period. Firstly, there is one clear down -valley limit to the fresh hummocky drift in each valley system. Secondly, with the exception of the isolated Glen Almond area, the spread of moundy drift continues from one valley system to the next via interconnecting valleys. Thirdly, the pattern of glaciers inferred from the evidence appears to be inherently probable.There are five principal reasons for concluding that these glaciers existed during pollen Zone III. Sediments from present or former lakes just outside the limit of the last Glen Almond glacier and just outside the terminal moraine of the last Teith glacier contain pollen from much of the Lateglacial, including the interstadial preceding Zone III, but the earliest deposits found immediately inside the Teith moraine belong to the Postglacial. Secondly, the Teith terminal moraine occupies a position at the mouth of a Highland valley analogous to those of the neighbouring Menteith and Loch Lomond terminal moraines that were dated by pollen and radiocarbon analyses as having been formed in Zone III. Thirdly, a suite of outwash terraces formed beyond the Teith moraine passes into a buried fan that was largely deposited during a period of low sea -level when the adjacent Menteith moraine was being formed, that is in Zone III. Fourthly, whereas the largest glaciers in the thesis area advanced eastwards from the west Highland watershed area, other major glaciers flowed westwards from this watershed to the western coast. It is generally considered on morphological evidence that the glaciers that terminated at Benderloch, Loch Leven, Loch Linnhe, Loch Shiel and Loch Morar represented the Loch Lomond Readvance in Zone III, whilst radiocarbon dating of organic material proves that the Benderloch glaciers existed during Zone III. Fifthly, it seems entirely logical to expect that the limits in the Highland part of western Perthshire that do not happen to have been independently dated by pollen studies should have been formed in the same period as those that have been dated.It is concluded that the last valley glaciers in western Perthshire were part of the Loch Lomond Readvance that is correctly correlated with pollen Zone III

    This study investigated the relationship between noncognitive factors and achievement of academically successful African American students attending predominantly White institutions of higher education (PWIs). It explored the reasons many African American students at PWIs are able to ensure and continue their academic success. Also, the motivational strategies utilized by some African American students on majority race campuses to overcome obstacles in order to maintain their achievement levels were examined. Collective case study research methods were employed. This was accomplished through the use of eleven African American juniors and seniors who are achieving academically while attending Louisiana State University. To discover themes and patterns, in-depth semistructured interviews, participant-observer sessions, and document reviews were conducted. Analyses of the data revealed that being determined and motivated to succeed were important achievement strategies for all of the Black women and men who participated in this study. In addition, motivation was garnered from their mentors, friends, churches, and other support networks. Moreover, motivation stemmed from a strong self-concept, the thrill of a challenge, love of learning, as well as believing in their abilities to succeed which was united by deep religious convictions. The findings further indicated that the participants strongly feel that becoming involved and participating in predominantly Black organizations can circumvent feelings of alienation and isolation that many African American experience as students while attending predominantly White colleges and universities

    Human Papillomavirus (HPV) Vaccination Status Among University Freshmen in Hawai‘i

    Purpose/Background: The HPV vaccine provides immunity against nine HPV strains that cause cancer and genital warts. It is recommended for 11 to 12 year olds, and catch-up immunization is recommended for females 13 to 26 years old and males 13 to 21 years old. College students represent an important population for HPV vaccination due to their increased risk for HPV infection. Despite the benefits of the HPV vaccine, its coverage rates are low in Hawaii. Hawai‘i is the home of two large universities on two islands that are representative of Hawai‘i’s populations, including Native Hawaiians, Filipinos, and Pacific Islanders. The purpose of this study was to assess the current HPV and HPV vaccine knowledge, barriers and beliefs among incoming Freshmen university students at University of Hawai‘i at Mānoa and University of Hawai‘i at Hilo. Materials & Methods: In 2016, 200 University of Hawai‘i at Mānoa (UHM) and University of Hawai‘i at Hilo (UHH) Freshmen students responded to a survey that assessed their knowledge and awareness of HPV, the HPV vaccine, their current vaccination status, and barriers and motivators to vaccination. Descriptive statistics were used to summarize each survey variable first for all students and then separately for each campus. Results: Overall 76% of Freshmen from both campuses heard of the HPV vaccine and 54% reported hearing it from their health care provider. Only 28% UHM and 23% UHH Freshmen students have received partial (1-2 shots) or completed doses of the HPV vaccine. For those who received the vaccine, 45% reported that they were told by their parent and 43% were told by their doctor. For the 147 students who did not receive the vaccine, 28% reported that they are still not sure to get it and 20% need more information. Their main reasons for not receiving the HPV vaccine were: their doctor did not mention the vaccine to him/her (44%), he/she never knew about the vaccine (18%), and they don\u27t know enough about the vaccine (17%). Discussion/Conclusion: Although the HPV vaccine has been available for 13 years, young adults remain unvaccinated. Freshmen students reported that they are informed about the vaccine, but were not vaccinated because of the lack of parental and/or healthcare provider recommendation. With no active education campaigns in Hawaii promoting the HPV vaccine at college campuses, a first step to increasing vaccination rates is to develop a health education campaign to inform students of the HPV vaccine and its availability at campus clinics and neighboring pharmacies

    The radiation of elliptical and bicylindrically focused piston transducers

    Get PDF
    Expressions for the radiation of elliptical and bicylindrically focused piston transducers are derived within the Fresnel approximation. For the axial fields, the result takes the form of either a simple analytical expression (small perturbations from the circular piston case), a single quadrature in a real variable (unfocused and some focused cases), or a single quadrature in a complex variable (near focal points). The full fields are represented by a series of localized, Gauss–Hermite eigenfunctions. Numerical examples are used to illustrate the agreement of the two solutions for on‐axis fields and to shed light on questions of the convergence and the selection of initial scaling parameters of the Gauss–Hermite expansion

    Effect of questions used by psychiatrists on therapeutic alliance and adherence

    Background Psychiatrists' questions are the mechanism for achieving clinical objectives and managing the formation of a therapeutic alliance – consistently associated with patient adherence. No research has examined the nature of this relationship and the different practices used in psychiatry. Questions are typically defined in binary terms (e.g. ‘open’ v. ‘closed’) that may have limited application in practice. Aims To undertake a detailed examination of the types of questions psychiatrists ask patients and explore their association with the therapeutic alliance and patient adherence. Method A coding protocol was developed to classify questions from 134 out-patient consultations, predominantly by syntactic form. Bivariate correlations with measures of patient adherence and the therapeutic alliance (psychiatrist-rated) were examined and assessed using generalised estimating equations, adjusting for patient symptoms, psychiatrist identity and amount of speech. Results Psychiatrists used only four of ten question types regularly: yes/no auxiliary questions, ‘wh-’ questions, declarative questions and tag questions. Only declarative questions predicted better adherence and perceptions of the therapeutic relationship. Conversely, ‘wh-’ questions – associated with positive symptoms – predicted poorer perceptions of the therapeutic relationship. Declarative questions were frequently used to propose an understanding of patients' experiences, in particular their emotional salience for the patient. Conclusions A refined defining of questioning practices is necessary to improve communication in psychiatry. The use of declarative questions may enhance alliance and adherence, or index their manifestation in talk, e.g. better mutual understanding. The function of ‘so’-prefaced declaratives, also used in psychotherapy, is more nuanced than negatively connotated ‘leading’ questions. Hearable as displays of empathy, they attend closely to patient experience, while balancing the tasks of assessment and treatment

    Experiences of UK African-Caribbean Prostate Cancer Survivors of Discharge to primary care

    Get PDF
    Objective: Black men are three times more likely to develop prostate cancer (PCa), to do so at a younger age and to experience a more aggressive form than White men. This study aims to understand the experiences of African-Caribbean men with respect to their discharge to primary care following successful PCa treatment and the challenges associated with survivorship. Design: Eight African-Caribbean men, who had been successfully treated for PCa, were recruited through the charity BME Cancer Communities. They participated in a focus group, which took place on the premises of the charity and was audio-recorded. The recording was transcribed and the data were analysed employing thematic analysis. Results: Three overarching themes were developed: Discharge - misconceptions and uncertainties; Survivorship - challenges and ways of coping; Black men and PCa: real and potential discrimination. Participants expressed concerns regarding the lack of information and clarity about what discharge meant, the quality of follow-up care, especially the levels of specialist knowledge among GPs, and the impact of side-effects, particularly erectile dysfunction (ED). Participants linked ED with stereotypes of Black male sexuality, particularly in relation to difficulties of expressing their emotions and psychological distress. African-Caribbean men face particular challenges in dealing with the side-effects of treatment for PCa, which are linked to socially-constructed ideas of masculinity. Conclusion: There needs to be a greater focus in primary care on understanding these issues and providing individualised culturally-sensitive care. In particular, GPs should be aware of sensitivities concerning help-seeking related to culturally-mediated understandings of masculinity

    The transition to a green economy offers a bright future for Southeast Asia. It's not only a US$1 trillion market opportunity by 2030 across the region's economies. It's also a pathway to a sustainable future, one that is resilient to the climate crisis, more secure for nations, healthier for residents, and inclusive for all.To guide this radical transformation, we studied employment markets across six countries—Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam—and conducted 80 interviews with employers, researchers, and nongovernmental organisations (NGOs). This report, supported by J.P. Morgan, identifies steps that leaders across sectors— governments, funders, NGOs, investors, and employers—can take to ensure the emerging green economy achieves a "just transition" that leaves no one behind
