ECOSYSTEM APPROACH TO FISHERIES MANAGEMENT IN THE SOUTHERN BENGUELA: A WORKSHOP OVERVIEW

A workshop was held in Cape Town in December 2002 to introduce the concept of an ecosystem approach to fisheries (EAF) management in the southern Benguela, and to examine the options for implementing an EAF in South Africa. The workshop considered alternative modelling approaches that may have potential for an ecosystem approach to fisheries. Consensus was that an EAF should be implemented in South Africa through an incremental process, starting immediately. Ecosystem models can be used to provide guidance on reference points and broader management objectives still currently set on the basis of single-species assessments. Such additional information would be incorporated into the decision-making process, and comments received at a management level would also feed back to the modelling process. It was suggested that, at the scientific level, an ecosystem modelling perspective could be incorporated into existing single-species management recommendations by testing them with ecosystem models. Compilation of an “ecosystem considerations” document was recommended to initiate the process. It was proposed that a dedicated EAF working group be established in South Africa to advise on the process of implementing an EAF in the various fisheries, and to provide overarching guidance and to ensure consistency in integrating existing data and information for informing the management process

A cross sectional survey of attitudes, behaviours, barriers and motivators to cycling in University students

High rates of active travel are essential aspects of healthy communities. Increasing cycling participation has the potential to address a range of long-term health and societal issues, and positively contribute to the health and sustainability agenda. Universities have been proposed as appropriate settings for a healthy place approach however, there is a paucity of evidence on student cycling. Therefore the aim of this paper is to explore the motivators and barriers to cycling amongst University students.An online cross sectional survey of young adults (18-25 years) studying at an urban United Kingdom university was undertaken. Using convenience sampling participants were surveyed on levels of cycling (e.g. daily, weekly) alongside perceptions, barriers and motivators to cycling activity.194 responses were received of which 55% were male, 54% owned a bicycle and 14% were regular cyclists. Cycling motivators were enjoyment and improving fitness; especially amongst regular cyclists. However, weather and safety concerns were the main barriers. The majority (85%) felt more should be done to encourage cycling, with 70% stating cycling was easier 'elsewhere'. Respondents felt cycling had an important environmental element (67%), although less than 8% cited congestion and pollution reduction as a reason for cycling and 64% believed there were more barriers to cycling than driving.This study suggests that levels of cycling within a university setting may be higher than the general population and the appreciation of the merits of cycling are well recognised. In addition motivators and barriers are similar to the wider population. However more research is required, especially with occasional and non-cyclists, to understand how best to address the 'value-action' gap highlighted between cycling attitudes and behaviour amongst university students. © 2017

Harm-reduction approaches for self-cutting in inpatient mental health settings:development and preliminary validation of the Attitudes to Self-cutting Management (ASc-Me) Scale

IntroductionHarm-reduction approaches for self-harm in mental health settings have been under-researched.AimTo develop a measure of the acceptability of management approaches for self-cutting in mental health inpatient settings.MethodsStage one: scale items were generated from relevant literature and staff/service user consultation. Stage two: A cross-sectional survey and statistical methods from classical test theory informed scale development.Results/FindingsAt stage one N=27 staff and service users participated. At stage two N=215 people (n=175 current mental health practitioners and n=40 people with experience of self-cutting as a UK mental health inpatient) completed surveys. Principal components analysis revealed a simple factor structure such that each method had a unique acceptability profile. Reliability, construct validity, and internal consistency were acceptable. The harm-reduction approaches 'advising on wound-care' and 'providing a first aid kit' were broadly endorsed; 'providing sterile razors' and 'maintaining a supportive nursing presence during cutting' were less acceptable but more so than seclusion and restraint.DiscussionThe Attitudes to Self-cutting Management scale is a reliable and valid measure that could inform service design and development.Implications for practiceNurses should discuss different options for management of self-cutting with service users. Harm reduction approaches may be more acceptable than coercive measures. This article is protected by copyright. All rights reserved.</p

Quantum Optical Systems for the Implementation of Quantum Information Processing

We review the field of Quantum Optical Information from elementary considerations through to quantum computation schemes. We illustrate our discussion with descriptions of experimental demonstrations of key communication and processing tasks from the last decade and also look forward to the key results likely in the next decade. We examine both discrete (single photon) type processing as well as those which employ continuous variable manipulations. The mathematical formalism is kept to the minimum needed to understand the key theoretical and experimental results

Association of Accelerometry-Measured Physical Activity and Cardiovascular Events in Mobility-Limited Older Adults: The LIFE (Lifestyle Interventions and Independence for Elders) Study.

BACKGROUND:Data are sparse regarding the value of physical activity (PA) surveillance among older adults-particularly among those with mobility limitations. The objective of this study was to examine longitudinal associations between objectively measured daily PA and the incidence of cardiovascular events among older adults in the LIFE (Lifestyle Interventions and Independence for Elders) study. METHODS AND RESULTS:Cardiovascular events were adjudicated based on medical records review, and cardiovascular risk factors were controlled for in the analysis. Home-based activity data were collected by hip-worn accelerometers at baseline and at 6, 12, and 24&nbsp;months postrandomization to either a physical activity or health education intervention. LIFE study participants (n=1590; age 78.9±5.2 [SD] years; 67.2% women) at baseline had an 11% lower incidence of experiencing a subsequent cardiovascular event per 500&nbsp;steps taken per day based on activity data (hazard ratio, 0.89; 95% confidence interval, 0.84-0.96; P=0.001). At baseline, every 30&nbsp;minutes spent performing activities ≥500&nbsp;counts per minute (hazard ratio, 0.75; confidence interval, 0.65-0.89 [P=0.001]) were also associated with a lower incidence of cardiovascular events. Throughout follow-up (6, 12, and 24&nbsp;months), both the number of steps per day (per 500&nbsp;steps; hazard ratio, 0.90, confidence interval, 0.85-0.96 [P=0.001]) and duration of activity ≥500&nbsp;counts per minute (per 30&nbsp;minutes; hazard ratio, 0.76; confidence interval, 0.63-0.90 [P=0.002]) were significantly associated with lower cardiovascular event rates. CONCLUSIONS:Objective measurements of physical activity via accelerometry were associated with cardiovascular events among older adults with limited mobility (summary score &gt;10 on the Short Physical Performance Battery) both using baseline and longitudinal data.

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

A protocol for a systematic review of knowledge translation strategies in the allied health professions

<p>Abstract</p> <p>Background</p> <p>Knowledge translation (KT) aims to close the gap between knowledge and practice in order to realize the benefits of research through (a) improved health outcomes, (b) more effective health services and products, and (c) strengthened healthcare systems. While there is some understanding of strategies to put research findings into practice within nursing and medicine, we have limited knowledge of KT strategies in allied health professions. Given the interprofessional nature of healthcare, a lack of guidance for supporting KT strategies in the allied health professions is concerning. Our objective in this study is to systematically review published research on KT strategies in five allied health disciplines.</p> <p>Methods</p> <p>A medical research librarian will develop and implement search strategies designed to identify evidence that is relevant to each question of the review. Two reviewers will perform study selection and quality assessment using standard forms. For study selection, data will be extracted by two reviewers. For quality assessment, data will be extracted by one reviewer and verified by a second. Disagreements will be resolved through discussion or third party adjudication. Within each profession, data will be grouped and analyzed by research design and KT strategies using the Effective Practice and Organisation of Care Review Group classification scheme. An overall synthesis across professions will be conducted.</p> <p>Significance</p> <p>A uniprofessional approach to KT does not represent the interprofessional context it targets. Our findings will provide the first systematic overview of KT strategies used in allied health professionals' clinical practice, as well as a foundation to inform future KT interventions in allied healthcare settings.</p
