The Impact

CCD detectors are rapidly replacing the photographic plate and photomultiplier in satellite observations used for orbital improvement. This includes both phenomena timings as well as tangent plane astrometry. In most cases this change has been for the better, but in some areas there has been no gain – even a loss. We will review this change in terms of the recent history of satellite observations. The impact of the CCD will be discussed in terms of its applications, and the increase in precision it affords. Finally, a few things will be said about future directions, especially about spin-off applications.

Abstract In this chapter, we focus on mathematical models of tuberculosis epidemiology (TB) that include interactions with HIV and an explicit representation of transmission. We review the natural history of TB and illustrate how its features are simplified and incorporated in mathematical models. We then review the ways HIV influences the natural history of TB, the interventions that have been considered in models, and the way these individual-level effects are represented in models. We then go on to consider population-level effects, reviewing the TB/HIV modelling literature. We first review studies whose focus was on purely epidemiological modelling, and then studies whose focus was on modelling the impact of interventions. We conclude with a summary of the uses and achievements of TB/HIV modelling and some suggested future directions.

Consultation Paper

The Ministry of Justice’s Consultation Paper – Strengthening Probation, Building Confidence – launched by Justice Secretary David Gauke in July 2018, represents a revisionist view of the recent history of the probation service in which many of its assertions are incoherent, disingenuous and disconnected from the lived realities of both those who offend and local communities having to deal with the impact of austerity on local services. In addition, the consultation process itself is disingenuous in that it presents the failure of the Transforming Rehabilitation initiative as one of technical oversights and misjudgements that can be put right through a series of relatively minor adjustments. Answers to the 17 consultation questions, however insightful and helpful they may be, will do nothing to deal with the underlying difficulties of Transforming Rehabilitation.

From Republic to Empire: Reflections on the Early Provincial Architecture of the Roman West

The Impact

Nobody who has worked in the field of late Republican and early Imperial Rome can fail to be aware how remarkably little archaeological evidence we have of any specifically Roman presence in the provinces of which Rome was in political and military control during the last century of the Republic. In the east, where she was faced with a civilization older and richer than her own, this is intelligible enough. But for the student of the spread of Roman institutions and ideas in the west the gap is embarrassing. In Roman Britain we have no difficulty whatever in identifying the Gallic precedents for the settlement that followed the Roman conquest. But what lay behind the Caesarian and Augustan settlement in Gaul itself? In terms of the recent history of the area it would be reasonable to expect that in the south, at any rate, it should have been rooted in local Republican Roman practice; and yet there is remarkably little evidence of any such roots in the surviving remains. Much the same is true of Spain and Africa. Why is this? Is it that the impact of the early Imperial settlement was so strong that it swept away all trace of what had gone before? Or is it simply that the Republican Roman presence in these territories was not of a character to leave any substantial mark on the archaeological record?

Tobacco use in China is a substantial threat to global health and, after many years of poor implementation of tobacco control, attitudes are changing for the better and substantial actions may be about to follow. This commentary reviews the impact of tobacco and the recent history of tobacco control in China, the context and implications of new encouraging legislation.

AbstractOver the last decade, several groups of young (mainly low-mass) stars have been discovered in the solar neighbourhood (closer than ~100pc), thanks to cross-correlation between X-ray, optical spectroscopy and kinematic data. These young local associations – including an important fraction whose members are Hipparcos stars – offer insights into the star formation process in low-density environments, shed light on the substellar domain, and could have played an important role in the recent history of the local interstellar medium. Ages estimates for these associations have been derived in the literature by several ways (HR diagram, spectra, Li and Hα widths, expansion motion, etc.). In this work we have studied the kinematic evolution of young local associations and their relation to other young stellar groups and structures in the local interstellar medium, thus casting new light on recent star formation processes in the solar neighbourhood. We compiled the data published in the literature for young local associations, including the astrometric data from the new Hipparcos reduction. Using a realistic Galactic potential we integrated the orbits for these associations and the Sco-Cen complex back in time. Combining these data with the spatial structure of the Local Bubble and the spiral structure of the Galaxy, we propose a recent history of star formation in the solar neighbourhood. We suggest that both the Sco-Cen complex and young local associations originated as a result of the impact of the inner spiral arm shock wave against a giant molecular cloud. The core of the giant molecular cloud formed the Sco-Cen complex, and some small cloudlets in a halo around the giant molecular cloud formed young local associations several million years later. We also propose a supernova in young local associations a few million years ago as the most likely candidate to have reheated the Local Bubble to its present temperature.

History Of Study

This is a brief, interconnected review of some of the extensive work published in the last few years on the history of study into communication. It highlights in particular the expansion of this work to include international contexts and the examination of how teaching programmes as well as research activity have helped to institutionalize the area as one with a discrete, if much-debated, academic identity. Different originating contexts, historical links with professional practice and the impact of new media on the recent history both of teaching and research are among the themes addressed.

Impact of Preexisting Health Conditions on the Outcome of an Adverse Drug Reaction Alerting Program: Gastrointestinal Disorders Before Piroxicam and Sulindac Therapy

Objective: To assess the impact of data concerning preexisting serious gastrointestinal (GI) disorders before piroxicam and sulindac therapy in an acute adverse drug reaction alerting program. Design: Cohort study. Setting: Saskatchewan province's prescription drug and healthcare insurance system covering a population of approximately 1 million. Participants: The first 20 000 new patients who were dispensed piroxicam in 1982 and the first 20 000 patients who were dispensed sulindac in 1979-1981 through the Saskatchewan drug plan. Main Outcome Measures: Physician services and hospitalizations with a diagnosis of peptic ulceration or GI hemorrhage within 30 days of the first piroxicam or sulindac prescription. Results: Rates of physician services for peptic ulceration or GI hemorrhage in the 30 days after starting piroxicam or sulindac therapy for patients who had services or hospitalizations for serious stomach or duodenum disorders in the 90 days before their prescriptions were significantly greater than the corresponding rates for patients without a recent history of these conditions (piroxicam: odds ratio [OR] = 7.89; 95% confidence interval [CI] =5.71 to 10.91; p> 0.001; sulindac: OR = 24.08; 95% CI = 18.99 to 30.54; p < 0.001). Also, the rate of hospitalizations for peptic ulceration or GI hemorrhage in the 30 days after starting sulindac therapy for patients who had services for the conditions in the previous 90 days was significantly greater than the rate for patients who did not (OR = 10.91; 95% CI = 5.70 to 20.87; p> 0.001). Conclusions: Rates of serious GI disorders in patients taking piroxicam and sulindac with a recent history of such disorders were larger than those in the other patients. However, because the proportion of individuals with recent serious GI disorders is small, these differences are lost in an overall assessment of patients taking these drugs. Data regarding preexisting health conditions are essential in adverse drug reaction alerting programs and, indeed, in all evaluations of adverse reactions.
