The Impact of Dispersal Powers on Congregating Youth

Purpose: To present research which evaluated the impact of Dispersal Orders in an English town. Design/Methodology/Approach: The study used a mixed method design to, qualitatively, explore the impact of the intervention on young people and, quantitatively, the impact on recorded crime/anti-social behaviour. Findings: The use of Dispersal Orders in the town being studied highlighted a number of issues detrimental to young people. Powers appeared to be used to control the congregating rather than anti-social behaviour of young people and their use could increase young peoples’ feelings of vulnerability. Practical Implications: The findings suggest that Dispersal Orders (and the newer Public Spaces Protection Orders) may be ineffective if they are used without the focus of a specific anti-social behaviour issue. Social Implications: The findings suggest that the use of Dispersal Orders to deal with non anti-social behaviour issues are likely to alienate young people and have the potential to inadvertently place them at further risk. They also suggest that the Public Spaces Protection Order could very well exacerbate the substantial issues which have been identified in the present research. Originality/Value: This research is original and suggests that the negative findings of earlier pieces of research into Dispersal Orders can be replicated in very different geographical environments and in areas with low levels of general deprivation where no substantial anti-social behaviour issues were identified. Furthermore, it uses original data to contextualise contemporary developments in anti-social behaviour, namely the introduction of Public Spaces Protection Order

ENGLISH SECOND LANGUAGE (ESL) STUDENTS AS NEW MEMBERS OF A COMMUNITY OF PRACTICE: SOME THOUGHTS FOR LEARNING AND ASSESSMENT

This article reports on English second language (ESL) students’ experiences of academic writing in a university setting. It draws on the notion of community of practice to explain that it is not sufficient for academic literacy courses to concern themselves only with the questions relating to the development of student academic literacy. Rather they should also be concerned with how students learn in social contexts and what knowledge is included and what knowledge is excluded. Such an orientation is vital because academic writing in the context of the university is more than just the ability to read and write, it is often the basis for the evaluation of students and, as such, becomes a powerful gatekeeper

Young athletes under pressure?

Regular participation in exercise has long been known to result in cardiovascular adaptation. Historically, the ‘athlete’s heart’ hypothesis has encouraged a dichotomised view of the heart’s adaptation to sport, depending on whether the physical activity was either of isotonic activity (runners and swimmers) resulting in ‘cardiomegaly’ or of isometric effort (wrestlers and shot putters, ie, ‘strength’ athletes) with clear peripheral adaptations and an ‘obvious increase in cardiac size’. Today, the classification of sports according to their physiological demands acknowledges a greater diversity of exposure, depending on the physical activity, with an emphasis on a ‘graded transition’ between the main categories: dynamic, static and impact. Still, our understanding of the determinants of structural and functional cardiovascular adaptation to exercise are limited, and the consequences for health remain a matter of debate

Crystal structure of cobalt hydroxide carbonate Co2CO3(OH)(2): density functional theory and X-ray diffraction investigation

The cobalt carbonate hydroxide Co2CO3(OH)2 is a technologically important solid which is used as a precursor for the synthesis of cobalt oxides in a wide range of applications. It also has relevance as a potential immobilizer of the toxic element cobalt in the natural environment, but its detailed crystal structure is so far unknown. The structure of Co2CO3(OH)2 has now been investigated using density functional theory (DFT) simulations and powder X-ray diffraction (PXRD) measurements on samples synthesized via deposition from aqueous solution. Two possible monoclinic phases are considered, with closely related but symmetrically different crystal structures, based on those of the minerals malachite [Cu2CO3(OH)2] and rosasite [Cu1.5Zn0.5CO3(OH)2], as well as an orthorhombic phase that can be seen as a common parent structure for the two monoclinic phases, and a triclinic phase with the structure of the mineral kolwezite [Cu1.34Co0.66CO3(OH)2]. The DFT simulations predict that the rosasite-like and malachite-like phases are two different local minima of the potential energy landscape for Co2CO3(OH)2 and are practically degenerate in energy, while the orthorhombic and triclinic structures are unstable and experience barrierless transformations to the malachite phase upon relaxation. The best fit to the PXRD data is obtained using a rosasite model [monoclinic with space group P1121/n and cell parameters a = 3.1408 (4) Å, b = 12.2914 (17) Å, c = 9.3311 (16) Å and γ = 82.299 (16)°]. However, some features of the PXRD pattern are still not well accounted for by this refinement and the residual parameters are relatively poor. The relationship between the rosasite and malachite phases of Co2CO3(OH)2 is discussed and it is shown that they can be seen as polytypes. Based on the similar calculated stabilities of these two polytypes, it is speculated that some level of stacking disorder could account for the poor fit of the PXRD data. The possibility that Co2CO3(OH)2 could crystallize, under different growth conditions, as either rosasite or malachite, or even as a stacking-disordered phase intermediate between the two, requires further investigation

A preliminary assessment of the frequency, distribution and causes of mortality of beach cast cetaceans in the Sultanate of Oman, January 1999 to February 2002. Scientific Committee document SC/54/O4, International Whaling Commission, 26 April-10 May 2002, Shimonoseki, Japan

Data are presented on beach cast cetaceans recorded in central and southern Oman between January 1999 and February 2000 during systematic beach surveys. Crude encounter rates of cetacean specimens are comparable with previous published data and indicate relatively high levels of mortality of Tursiops sp. and Sousa plumbea. Over two-thirds of specimens are recorded as stranding state V with cause of mortality unknown. Of the remaining specimens, empirical and circumstantial evidence for cause of death is suggestive of interactions with fisheries activities in the majority of cases. Direct evidence of interactions between cetaceans and fisheries, including information on incidental catch, is also presented. Other possible causes of mortality are hypothesised. Two mass strandings of small cetaceans are also discussed. Given the high numbers (725 records) and diversity (18 spp.) of beach cast cetaceans recorded in Oman, and the value of specimens to scientific study and conservation and fisheries management, recommendations are made to expand the scope of research and application of data

Daily physical activity and related risk factors in COPD

Background Factors associated with reduced daily physical activity (DPA) in patients with COPD are still controversial. Physical inactivity in COPD increases risk of cardiovascular disease, frequent exacerbations, reduced health status, and increased symptoms. We hypothesised that reduced DPA in patients with COPD is independent of traditional risk factors including age and spirometry. Methods In this cross-sectional study, DPA (over 7 days) was assessed on 88 community stable patients with COPD and 40 controls free from cardiorespiratory disease. Spirometry, body composition, number of exacerbations, handgrip strength (HGS), modified Medical Research Council (mMRC), arterial stiffness, 6-min walking distance (6MWD) and BODE index were also determined. Frequent exacerbation was defined as ≥2 and non-frequent exacerbation < 2. Results Patients with COPD had reduced DPA and exercise capacity compared with controls similar in age, BMI and gender, p  0.05. The level of breathlessness was superior to lung function in predicting the level of DPA. Conclusion The level of DPA in COPD was independent of traditional risk factors. Breathlessness score is a better predictor of the DPA than lung function and handgrip strength

Revisiting the need for a literature search narrative: A brief methodological note

This is the author accepted manuscript. The final version is available from Wiley via the DOI inthis recordIn this method note, we question if the primary search strategy in a systematic review should be accompanied by a search narrative. A search narrative could offer a conceptual and contextual report on the search strategy, which we suggest might benefit the peer review of literature searches and increase engagement with, and discussion of, the literature search strategy from review stakeholders, topic experts, and lay users of research. Search narratives would also increase the transparency of decision-making in literature searching.Centre for Outcomes Research and Effectiveness (CORE)National Institute for Health Research (NIHR)Cochrane Common Mental Disorders (CCMD) Grou

Population weighted raster maps can communicate findings of social audits: examples from three continents

<p>Abstract</p> <p>Background</p> <p>Maps can portray trends, patterns, and spatial differences that might be overlooked in tabular data and are now widely used in health research. Little has been reported about the process of using maps to communicate epidemiological findings.</p> <p>Method</p> <p>Population weighted raster maps show colour changes over the study area. Similar to the rasters of barometric pressure in a weather map, data are the health occurrence – a peak on the map represents a higher value of the indicator in question. The population relevance of each sentinel site, as determined in the stratified last stage random sample, combines with geography (inverse-distance weighting) to provide a population-weighted extension of each colour. This transforms the map to show population space rather than simply geographic space.</p> <p>Results</p> <p>Maps allowed discussion of strategies to reduce violence against women in a context of political <it>sensitivity</it> about quoting summary indicator figures. <it>Time-series maps</it> showed planners how experiences of health services had deteriorated despite a reform programme; where in a country HIV risk behaviours were improving; and how knowledge of an economic development programme quickly fell off across a region. <it>Change maps</it> highlighted where indicators were improving and where they were deteriorating. Maps of <it>potential impact of interventions</it>, based on multivariate modelling, displayed how partial and full implementation of programmes could improve outcomes across a country. <it>Scale</it> depends on context. To support local planning, district maps or local government authority maps of health indicators were more useful than national maps; but multinational maps of outcomes were more useful for regional institutions. Mapping was useful to illustrate in which districts enrolment in religious schools – a <it>rare occurrence</it> - was more prevalent.</p> <p>Conclusions</p> <p>Population weighted raster maps can present social audit findings in an accessible and compelling way, increasing the use of evidence by planners with limited numeracy skills or little time to look at evidence. Maps complement epidemiological analysis, but they are not a substitute. Much less do they substitute for rigorous epidemiological designs, like randomised controlled trials.</p
