In this thesis, I use two strategies of inquiry to further our understanding of indirect short-selling constraints. First, I interview a series of experienced market practitioners to identify their attitudes towards indirect constraints. I find little support for D’Avolio’s (2002) suggestions that short-selling is inhibited by managers’ fear of tracking error and by the cultural pressures of a society that can vilify short-sellers. However, I am able to introduce a new, social, indirect constraint to the literature – the perception that short-selling is a form of ‘trading’ as distinct from ‘investment’, and the consequent lack of acceptance amongst stakeholders that this engenders. This constraint reveals a divide between the attitudes of the academic community and parts of the institutional practitioner community on the subject of short-selling. However, interviewees argue that this indirect constraint is diminishing over time. This raises the prospect of markets in practice converging in behaviour towards the markets assumed in classical asset pricing models, and has implications for market efficiency. My second strategy of inquiry is to use a large, new stock lending database to explore three risk-related indirect constraints to short-selling. I examine ‘crowded exits’, a general class of liquidity problem, and find that these are associated with statistically and economically significant losses for short-sellers. I also examine ‘manipulative short squeezes’, a liquidity problem arising from predatory trading. Consistent with theory and the literature on the subject, I find that these are rare for larger, more liquid stocks. However, when they do occur, these events generate statistically significant losses for short-sellers. Finally, I build upon the work of Gamboa-Cavazos and Savor (2007) and investigate the response of short-sellers to losses. I find that short-sellers close their positions in response to accounting losses and not simply in response to rising share prices. This is consistent with short-sellers’ use of risk management tools that are designed to crystallize small losses. These serve to limit the risk of potentially unlimited losses and to reduce short positions at times of heightened synchronization risk. Stocks subject to shortcovering in this manner do not subsequently under-perform the market. My findings demonstrate that a sophisticated group of traders, strongly associated with price setting, does not suffer from the bias known as loss realization aversion.

This thesis is concerned with the experiences and understandings of young people as they move from their final two years of compulsory education into a range of post-16 destinations including Further Education, work, apprenticeships and unemployment. The participants were all identified as being ‘hard to reach’ by school practitioners. The research responds to a need to deepen understanding of such young people ahead of the age of participation in education and training in England being raised to 18 in 2015. The research was conducted in the South West of England. The empirical research was undertaken between January 2008 and April 2010 and comprised semi-structured interviews with 51 young people who were interviewed between one and three times during that period. The data presented in this thesis is focused on 11 of those young people who were each interviewed on three occasions. The findings suggest similarities between the post-16 transition experiences of the young people participating here and those of young people in this age range, not identified as ‘hard to reach’. Notwithstanding these parallels, the research revealed that young peoples’ post-16 transitions and the aspirations they hold are often more nuanced than has been theorised in previous research. The findings raise questions about the implications of labelling young people, and 14-19 policy predicated upon assumptions regarding those who do not participate post-16. In conclusion it is suggested that at a time of continued economic uncertainty and UK youth unemployment approaching one million , young people need more flexibility in the school and post-16 experiences that are available and actively encouraged, rather than increased levels of constraint.

A major challenge to contemporary education is to meet the Government’s directive, depicted in OFSTED guidelines and the Department for Education’s Teacher Standards that all our learners make progress, are autonomous and are able to engage in independent learning. However they offer no guidance as to how this can be achieved. The research has built on earlier theories to close the gap between Government measurements of the quality of teaching and twenty-first century educational theories, with particular focus on learning talk. The primary intention of this research was to determine the impact that dynamically dialogic learning conversations, that is learning talk, have on deepening learning, and how they may be used to enable teachers to meet OFSTED’s requirement for all students to make progress. The data for this case study was collected through a process of lesson observations, interviews and focus-group discussions over a period of one year. Sixteen lessons were video-recorded for a variety of topics and the recordings were analysed in depth against established theories of learning and the complex patterns and relationships between the different types of student and teacher learning talk observed in the classroom. The outcome of the analysis is a set of observable characteristics of learning talk which form an Observation Database. The findings support the premise that learning talk in the classroom leads to deeper learning. The Observation Database contains of a set of tools for observing, evaluating and enabling learning talk in the classroom and therefore offers teachers the opportunity to demonstrate OFSTED criteria. The process of developing the Observation Database and the tools developed have been shared both locally and nationally to heighten awareness of learning talk in the classroom and its link to deeper learning.

Class of 2009 Abstract / OBJECTIVES: The purpose of this study was to expand the current knowledge regarding opinions about the consequences of DTCA, specifically in terms of their implications for pharmacy practice. We evaluated this by examining student pharmacist attitudes toward DTCA and their perception of its practical ramifications as they progressed through pharmacy coursework. We also compared attitudes of student pharmacists’ with those of practicing pharmacists’ as previously published. METHODS: Students at the University of Arizona College of Pharmacy, enrolled in their 1st, 2nd, and 3rd year of coursework, completed a questionnaire with 16 Likert-scale items soliciting levels of agreement with statements regarding DTCA. Two direct questions about overall support for DTCA and experience with patient questions regarding DTCA were included. Demographic data was also collected. RESULTS: No difference was found between groups of students with respect to attitudinal statements regarding DTCA when analyzed by ANOVA (p>0.05). Similar results were found for overall support for DTCA as analyzed by Chi-square (p>0.05). There was a statistically significant difference in overall support for DTCA between students and pharmacists when assessed by Chi-square (p<0.05). CONCLUSIONS: Pharmacists are more likely to not support DTCA, whereas student pharmacists are more likely to be uncertain of whether or not they support it. An obvious difference between these groups is practice experience, which probably increases exposure to DTCA. Though it is difficult to discern the cause of this difference in opinion, it may suggest a link between experience and attitudes toward advertising policy.

UA Open Access Publishing Fund / Background Missing outcome data is a threat to the validity of treatment effect estimates in randomized controlled trials. We aimed to evaluate the extent, handling, and sensitivity analysis of missing data and intention-to-treat (ITT) analysis of randomized controlled trials (RCTs) in top tier medical journals, and compare our findings with previous reviews related to missing data and ITT in RCTs. Methods Review of RCTs published between July and December 2013 in the BMJ, JAMA, Lancet, and New England Journal of Medicine, excluding cluster randomized trials and trials whose primary outcome was survival. Results Of the 77 identified eligible articles, 73 (95%) reported some missing outcome data. The median percentage of participants with a missing outcome was 9% (range 0 – 70%). The most commonly used method to handle missing data in the primary analysis was complete case analysis (33, 45%), while 20 (27%) performed simple imputation, 15 (19%) used model based methods, and 6 (8%) used multiple imputation. 27 (35%) trials with missing data reported a sensitivity analysis. However, most did not alter the assumptions of missing data from the primary analysis. Reports of ITT or modified ITT were found in 52 (85%) trials, with 21 (40%) of them including all randomized participants. A comparison to a review of trials reported in 2001 showed that missing data rates and approaches are similar, but the use of the term ITT has increased, as has the report of sensitivity analysis. Conclusions Missing outcome data continues to be a common problem in RCTs. Definitions of the ITT approach remain inconsistent across trials. A large gap is apparent between statistical methods research related to missing data and use of these methods in application settings, including RCTs in top medical journals.

Bitterness and humor, dogmatism and tolerance, unprofessional negligence and scholarly care characterize recent criticism of Swift's "Voyage to the Houyhnhnms." Many scholars have based their conclusions on the findings of earlier commentators rather than on Swift's work itself. Others have imposed a system of their own upon the fourth voyage, sometimes without regard for incontrovertible evidence against their views. Consequently, these scholars often reveal more about themselves than about Swift and his work. Although only a few really new ideas have been presented since 1958 which help to explain the Dean's motivation and intentions, a number of new interpretations of the fourth voyage of Gulliver's Travels clarify some of Swift's purposes. Generally, recent critics can be divided into three groups: those who believe that the Houyhnhnms are Swift's moral ideal for mankind; those who contend that the Houyhnhnms are not Swift's moral ideal; and those who suggest that Swift's moral ideal for man lay somewhere between the Houyhnhnm and the Yahoo.
