#1
Michael J Davis, Robert Janke
The effect of limitations in the structural detail available in a network model on contamination warning system (CWS) design was examined in case studies using the original and skeletonized network models for two water distribution systems (WDSs). The skeletonized models were used as proxies for incomplete network models. CWS designs were developed by optimizing sensor placements for worst-case and mean-case contamination events. Designs developed using the skeletonized network models were transplanted into the original network model for evaluation...

INTRODUCTION: Transdisciplinary teams are increasingly regarded as integral to conducting effective research. Similarly, knowledge translation is often seen as a solution to improving the relevance and benefits of health research. Yet, whether, how, for whom and under which circumstances transdisciplinary research influences knowledge translation is undertheorised, which limits its potential impact. The proposed research aims to identify the contexts and mechanisms by which transdisciplinary research contributes to developing shared understandings and behaviours of knowledge translation between team members...

Efficacious operation for dam and reservoir system could guarantee not only a defenselessness policy against natural hazard but also identify rule to meet the water demand. Successful operation of dam and reservoir systems to ensure optimal use of water resources could be unattainable without accurate and reliable simulation models. According to the highly stochastic nature of hydrologic parameters, developing accurate predictive model that efficiently mimic such a complex pattern is an increasing domain of research...

BACKGROUND: The increasing use of Web-based solutions for health prevention and promotion presents opportunities to improve self-management and adherence to guideline-based therapy for individuals with type 2 diabetes (T2DM). Despite promising preliminary evidence, many users stop using Web-based solutions due to the burden of data entry, hidden costs, loss of interest, and a lack of comprehensive features. Evaluations tend to focus on effectiveness or impact and fail to evaluate the nuanced variables that may interact to contribute to outcome success (or failure)...

BACKGROUND: Disparity-reduction programs have been shown to vary in the degree to which they achieve their goal; yet the causes of these variations is rarely studied. We investigated a broad-scale program in Israel's largest health plan, aimed at reducing disparities in socially disadvantaged groups using a composite measure of seven health and health care indicators. METHODS: A realistic evaluation was conducted to evaluate the program in 26 clinics and their associated managerial levels...

INTRODUCTION: The lack of understanding of how complex integrated care programmes achieve their outcomes due to the lack of acceptable methods leads to difficulties in the development, implementation, adaptation and scaling up of similar interventions. In this study, we evaluate an integrated care network, the National University Health System (NUHS) Regional Health System (RHS), consisting of acute hospitals, step down care, primary care providers, social services and community partners using a theory-driven realist evaluation approach...

Decision matrix method is preferred as a measure of risk evaluation considering the risk value obtained by two risk factors such as the likelihood and severity of the hazard. However, it has some deficiencies since crisp risk score is assigned for the likelihood and severity. In this paper, fuzzy logic based safety evaluation method to enhance the risk assessment process is introduced to overcome the uncertainties encountered in classical decision matrix risk assessment method. The proposed method is of more realistic evaluation of the risks which may be available in the mechanized coal panels in Turkey...

Cash transfer programs (CTs) have been rigorously evaluated since their inception in the 1990s. However, to date, there has been no study critically examining the utility of the methodological approaches used to evaluate CTs. This article reviews the approaches used to evaluate CTs in sub-Saharan Africa (SSA) to provide recommendations for improving future CTs evaluations. We conducted searches for CTs evaluation studies in SSA in the peer-reviewed and grey literature using electronic databases, hand searching of selected journals, organisational websites, Google Scholar and Scirus Internet search engines...

Continuous assessment of respiratory status is one of the cornerstones of modern intensive care unit (ICU) monitoring systems. Electrical impedance tomography (EIT), although with some constraints, may play the lead as a new diagnostic and guiding tool for an adequate optimization of mechanical ventilation in critically ill patients. EIT may assist in defining mechanical ventilation settings, assess distribution of tidal volume and of end-expiratory lung volume (EELV) and contribute to titrate positive end-expiratory pressure (PEEP)/tidal volume combinations...

AIM: Malnutrition has multiple causes, not just a lack of calories. We explored the successes and barriers of an innovative, comprehensive programme in Madagascar that educated mothers in particular about nutrition. METHODS: The outpatient programme in Antananarivo treats 2,400 malnourished children from 6-59 months each year. The 35-day programme comprises health checks, cooking demonstrations, the distribution of enriched flour supplements and two food-related games that are called Nutricartes and are based on boards and picture cards...

BACKGROUND: Access times for, the costs and overload of hospital services are an increasingly salient issue for healthcare managers in many countries. Rising demand for hospital care has been attributed partly to unplanned admissions for older people, and among these partly to the increasing prevalence of dementia. The paper makes a preliminary evaluation of the logic model of a Dementia Learning Community (DLC) intended to reduce unplanned hospital admissions from care homes of people with dementia...

(1) Background: Remote communities in Canada lack an equitable emergency medical response capacity compared to other communities. Community-based emergency care (CBEC) training for laypeople is a model that has the potential to enhance the medical emergency response capacity in isolated and resource-limited contexts. The purpose of this study was to understand the characteristics of medical emergencies and to conceptualize and present a framework for what a medical emergency is for one remote Indigenous community in northwestern Ontario, in order to inform the development of CBEC training...

M Steer, A I Machin
Background: Local authorities (LAs) have statutory responsibility to reduce health inequalities and improve public health. Place-based approaches may positively influence service provision yet little is known about their implementation and potential for reducing inequality through health and wellbeing improvements. An English LA implemented a place-based working (PBW) pilot in a small geography during austerity measures in the north of England. This involved three strands (early intervention, estate services and community intelligence) which were introduced separately and covered overlapping geographies...

Emily Joan Darlington, Nolwenn Violon, Didier Jourdan
BACKGROUND: Implementing complex and multi-level public health programmes is challenging in school settings. Discrepancies between expected and actual programme outcomes are often reported. Such discrepancies are due to complex interactions between contextual factors. Contextual factors relate to the setting, the community, in which implementation occurs, the stakeholders involved, and the characteristics of the programme itself. This work uses realist evaluation to understand how contextual factors influence the implementation process, to result in variable programme outcomes...

For patients living with chronic illnesses, self-care has been linked with positive outcomes such as decreased hospitalisation, longer lifespan, and improved quality of life. However, despite calls for more and better self-care interventions, behaviour change trials have repeatedly fallen short on demonstrating effectiveness. The literature on heart failure (HF) stands as a case in point, and a growing body of HF studies advocate realist approaches to self-care research and policymaking. We label this trend the 'realist turn' in HF self-care...
