Measuring the impact of Educational Interventions on the Academic Performance of Academic Development Students in Second-Year Microeconomics

This paper analyses the impact of educational interventions made in the first- and second-year microeconomics courses on academic development students’ final mark in the second-year course. It also addresses issues of methodology, specification, and statistical analysis with respect to other studies in the field. The results suggest that the educational interventions in the first-year had a positive impact on the academic performance of the academic development cohort, relative to the mainstream cohort for the first period (2000-2002). The results also suggest that the educational interventions introduced in the second period (2003-2005), in the form of voluntary workshops for the academic development cohort, also improved the academic performance of this cohort relative to that of mainstream students.

On estimating scale invariance in stratocumulus cloud fields

Examination of cloud radiance fields derived from satellite observations sometimes indicates the existence of a range of scales over which the statistics of the field are scale invariant. Many methods were developed to quantify this scaling behavior in geophysics. The usefulness of such techniques depends both on the physics of the process being robust over a wide range of scales and on the availability of high resolution, low noise observations over these scales. These techniques (area perimeter relation, distribution of areas, estimation of the capacity, d0, through box counting, correlation exponent) are applied to the high resolution satellite data taken during the FIRE experiment and provides initial estimates of the quality of data required by analyzing simple sets. The results of the observed fields are contrasted with those of images of objects with known characteristics (e.g., dimension) where the details of the constructed image simulate current observational limits. Throughout when cloud elements and cloud boundaries are mentioned; it should be clearly understood that by this structures in the radiance field are meant: all the boundaries considered are defined by simple threshold arguments

Structures observed on the spot radiance fields during the FIRE experiment

Three Spot images taken during the FIRE experiment on stratocumulus are analyzed. From this high resolution data detailed observations of the true cloud radiance field may be made. The structure and inhomogeneity of these radiance fields hold important implications for the radiation budget, while the fine scale structure in radiance field provides information on cloud dynamics. Wieliki and Welsh, and Parker et al., have quantified the inhomogeneities of the cumulus clouds through a careful examination of the distribution of cloud (and hole) size as functions of an effective cloud diameter and radiance threshold. Cahalan (1988) has compared for different cloud types of (stratocumulus, fair weather cumulus, convective clouds in the ITCZ) the distributions of clouds (and holes) sizes, the relation between the size and the perimeter of these clouds (and holes), and examining the possibility of scale invariance. These results are extended from LANDSAT resolution (57 m and 30 m) to the Spot resolution (10 m) resolution in the case of boundary layer clouds. Particular emphasis is placed on the statistics of zones of high and low reflectivity as a function of a threshold reflectivity

The Paris Peace Conference of 1919 and the History of Sovereignty

This lecture will provide an introduction to Smith's monograph project on the locus and attributes of sovereignty and the peace conference that sought to close down the Great War. Smith begins at the conceptual level, but explaining sovereignty as a category of analysis. He then endeavors to show what a focus of sovereignty adds to an understanding of the historically specific international system that created the Paris Peace Conference and was created by it.Ohio State UniversityMershon Center for International Security Studies.Event Web page, M4V video, event photo

The saga of James Lucett and the process for curing insanity, Part 2 (1814-38):'Insanity cured'

Following the collapse of the Delahoyde and Lucett joint enterprise, James Lucett resumed practice on his own account. He continued to implement his 'process', promoting it as a unique cure for intractable cases of insanity. For two decades he pursued his activities, with varying success, at different locations in the London area. He maintained his public profile by extensive advertising, letters to newspapers and published pamphlets, extolling his unique 'discovery' and recounting claims of successful cures achieved. Accusations of quackery persisted along with other hostile criticism, particularly from medical men, which Lucett strongly challenged. Periodically he faced more serious difficulties due to legal infractions or financial hardships, but somehow Lucett survived most of these and persevered with his endeavours.</p

The saga of James Lucett and the process for curing insanity, Part 1 (1811–14):The rise and fall of Delahoyde and Lucett

James Lucett, a London clerk, claimed possession of a secret remedy for curing chronic insanity. In 1813, he and the Irish surgeon Charles Delahoyde secured royal and aristocratic patronage to implement their ‘process’ and opened a private asylum. They aroused great public interest after apparently remarkable results with hitherto intractable patients from Bethlem and Hoxton. Delahoyde and Lucett attained brief celebrity, but within a year it was evident that the dramatic recoveries were only temporary. Their venture collapsed in disarray and bankruptcy, and the episode was soon largely forgotten. Delahoyde fled to Ireland, but Lucett managed to re-establish himself in practice. This article narrates the origins, operation and failure of the enterprise. A second article will consider Lucett’s subsequent career

The effect of selected academic development programmes on the academic performance of academic development students at a South African university : an empirical study.

Includes abstract.Includes bibliographical references.The case studies that make up this thesis cover the three largest academic development programmes at the University of Cape Town. A variety of statistical methods are used to estimate the effect of educational interventions in selected first- and second-year academic development courses on the academic performance of academic development students in these courses and through to graduation, relative to mainstream students. In general, research in this area in South Africa and internationally has been characterised by small sample sizes and a lack of statistical rigour. Few studies control for the range of independent variables that can affect students’ academic performance, in addition to the academic development programme or course, and the great majority ignore the sampleselection problem that arises in the selection of students for academic development and mainstream programmes. The theoretical rationale underpinning this thesis is informed by the postpositivist and evidence-based approaches to empirical investigation. Demographic, academic and other data for some 9000 students for the years 1999?2005 was obtained from the university’s data base and academic departments. Statistical techniques including multivariate analysis and propensity score matching are used in an attempt to finesse the problems associated with the use of non-experimental data as students are selected into different courses and programmes
