    Tubercular bronchial glands: their diagnosis and treatment in relation to pulmonary tuberculosis

    Get PDF
    Many cases present themselves at hospital showing signs of early pulmonary tuberculosis, which upon investigation appear to be the result of pressure on the lungs by enlarged bronchial glands. Some years ago, Percy Kidd drew attention to this occurrence but did not suggest any specific treatment. In view of the fact that hospitals for tuberculosis refuse so far as possible - all cases so far advanced that there is little hope of permanent arrest, it is most important to discriminate between early and advanced stages of the disease. It is the object of this thesis to discuss certain cases which at first sight appear far more advanced than is really the case, but in which the symptoms are misleading and apparently inconsistent, and to submit the theory that certain patients who appear to show signs of established pulmonary tuberculosis and who would be classed as fairly advanced cases, may in reality be suffering from enlarged bronchial glands, yielding very satisfactorily to treatment. This is based on a number of cases in the Brompton Hospital for Consumption and Diseases of the Chest and at a Tuberculosis Dispensary, of which six hospital cases have been appended in illustration. It will be noted that the patients are all children or young persons and this point is important - (1) because tuberculosis in children has a much greater tendency to become widespread than in adults; (2) because there is far greater hope of complete arrest while the trouble is still confined to the lymphatic system; (3) because if there be any truth in Dr. Batty Shawls contention that development of tuberculosis in later life is more often due to auto-infection than to re-infection from outside sources, it is the more important to arrest the disease in its earliest manifestations

    UK Sugar Beet Farm Productivity Under Different Reform Scenarios: A Farm Level Analysis

    The purpose of this paper is to study the effect that the imminent reform in the European Union (EU) sugar regime may have on farm productivity in the United Kingdom (UK). We perform the analysis on a sample of sugar beet farms representative of all the UK sugar beet regions. To estimate the changes in productivity, we estimate a multi-output cost function representing the cropping part of the farm, which is the component that would be mostly affected by the sugar beet reform. We use this cost function to compute the new allocation of outputs and inputs after the changes in the sugar beet quota and price support. This are subsequently used to compute measures of total factor productivity. Our results show slight decreases in the productivity at the individual farm level under both quota and price support reduction. However, when considering the aggregate level, the reduction in the price support shows significant increases in productivity, in contrast to the results obtained from a reduction in quota.EU sugar reform, UK agriculture, UK sugar beet production, multi-output cost function, total factor productivity, Agricultural and Food Policy, Productivity Analysis, Q00, D24,

    Tales of Two Referendums: Comparing Debate Quality between the UK and New Zealand Voting System Referendums of 2011

    Get PDF
    Two voting system referendums in the same year in two countries with institutional and cultural similarities provide an excellent opportunity for comparison, particularly given the significant differences in how those referendums were regulated and conducted. In New Zealand, a well-funded and balanced official information campaign led the debate; in Britain, the debate was dominated by campaign organisations. Based on content analysis of newspaper coverage of the campaigns, this paper explores how regulatory differences between these two cases shaped the quality of debate as reflected in media discourse. It finds that they made a difference, suggesting that positive interventions to promote better debate can work. It also concludes, however, that contextual factors are crucial too: interventions that work in one context will not necessarily work in another

    As calls for a ‘border poll’ on Irish unity grow, Alan Renwick and Katy Hayward report on new research on the politics and practicalities of any future referendum on both sides of the border

    Electoral Reform: What Do Political Scientists Know That Practitioners Do Not? Lessons from the UK Referendum of 2011

    Get PDF
    Political scientists might hope to offer practitioners involved in debates about electoral reform insights regarding either the process of reform or its potential effects. In respect of each of these, the practitioners whom we engage might by either elite decision-makers or the activists, journalists, and regular citizens who constitute the bedrock of democracy. The UK’s electoral reform referendum of 2011 offers a good opportunity to explore the degree to which political scientists in fact offer original insights in these various areas. The paper argues that, despite the great efforts that political scientists have expended in refining ever more sophisticated models of electoral system effects, elite practitioners have often – though not always – got there before us. By contrast, at least in the UK, practitioners sometimes fall short of political scientists in their understanding of how reform processes might unfold, and there is also a clear and strong need for political scientists to assist in educating public opinion. These findings have implications for how we should think about political science research: the research that practitioners most value is often not the research that has the highest prestige within the discipline

    The impact of cockpit automation on crew coordination and communication. Volume 1: Overview, LOFT evaluations, error severity, and questionnaire data

    Get PDF
    The purpose was to examine, jointly, cockpit automation and social processes. Automation was varied by the choice of two radically different versions of the DC-9 series aircraft, the traditional DC-9-30, and the glass cockpit derivative, the MD-88. Airline pilot volunteers flew a mission in the simulator for these aircraft. Results show that the performance differences between the crews of the two aircraft were generally small, but where there were differences, they favored the DC-9. There were no criteria on which the MD-88 crews performed better than the DC-9 crews. Furthermore, DC-9 crews rated their own workload as lower than did the MD-88 pilots. There were no significant differences between the two aircraft types with respect to the severity of errors committed during the Line-Oriented Flight Training (LOFT) flight. The attitude questionnaires provided some interesting insights, but failed to distinguish between DC-9 and MD-88 crews
