Sustainability Indicators Past and Present: What Next?

This paper discusses the current state of thought amongst the Sustainability Indicator (SI) community, what has been achieved and where we are succeeding and failing. Recent years have witnessed the rise of “alternative facts” and “fake news” and this paper discusses how SIs fit into this maelstrom, especially as they are themselves designed to encapsulate complexity into condensed signals and it has long been known that SIs can be selectively used to support polarized sides of a debate. This paper draws from chapters in a new edited volume, the “Routledge Handbook of Sustainability Indicators and Indices”, edited by the authors. The book has 34 chapters written by a total of 59 SI experts from a wide range of backgrounds, and attempts to provide a picture of the past and present, strengths and weaknesses of SI development today. This paper is an “analysis of those analyses”—a mindful reflection on reflection, and an assessment of the malign and benign forces at work in 2018 within the SI arena. Finally, we seek to identify where SIs may be going over the coming, unpredictable years

Helping chronically ill or disabled people into work: what can we learn from international comparative analyses?

This project has added to knowledge in five main areas: It has mapped the range and types of policies and interventions that have been implemented in Canada, Denmark, Norway, Sweden and the UK that may influence employment chances for chronically ill and disabled people. By doing so it has added to understanding about what has actually been tried in each country and what might be considered in others. It has refined a typology of the focussed interventions that have been identified, based on the underlying programme logic of the intervention, which aids strategic thinking about national efforts to help chronically ill and disabled people into work. It has produced systematic reviews of the impact of the focussed interventions on the employment chances of chronically ill and disabled people and demonstrated the use of the typology in helping to interpret the results of the evaluations. The project’s empirical analyses of individual-level data have identified how chronically ill people from different socio-economic groups have fared in the labour markets of the five countries over the past two decades. It has then tested these findings against hypotheses about the impact of macro-level labour market policies on chronically ill people to provide insights into the influence of the policy context. The project has contributed to methodological development in evidence synthesis and the evaluation of natural policy experiments. By studying a small number of countries in great depth, we gained greater understanding of the policies and interventions that have been tried in these countries to help chronically ill and disabled people into work, against the backdrop of the wider labour market and macro-economic trends in those countries. We then integrated evidence from the wider policy context into the findings of systematic reviews of effectiveness of interventions, to advance interpretation of the natural policy experiments that have been implemented in these countries

A comparison of the shock-absorbing properties of cervical disc prosthesis bearing materials

BACKGROUND DATA: Cervical arthroplasty offers theoretical advantages over traditional spinal fusion, including elimination of adjacent segment disease and elimination of the risk of pseudoarthrosis formation. Initial studies of cervical arthroplasty have shown promising results, however, the ideal design characteristics for disc replacement constructs have not been determined. The current study seeks to quantify the differences in the shock absorption characteristics of three commonly used materials in cervical disc arthroplasty. METHODS: Three different nucleus materials, polyurethane (PU), polyethylene (PE) and a titanium-alloy (Ti) were tested in a humidity- and temperature-controlled chamber. Ten of each nucleus type underwent three separate mechanical testing protocols to measure 1) dynamic stiffness, 2) quasi-static stiffness, 3) energy absorption, and 4) energy dissipation. The results were compared using analysis of variance. RESULTS: PU had the lowest mean dynamic stiffness (435 ± 13 N/mm, P < .0001) and highest energy absorption (19.4 ± 0.1 N/mm, P < .0001) of all three nucleus materials tested. PU was found to have significantly higher energy dissipation (viscous damping ratio 0.017 ± 0,001, P < .0001) than the PE or TI nuclei. PU had the lowest quasi-static stiffness (598 ± 23 N/mm, P < .0001) of the nucleus materials tested. A biphasic response curve was observed for all of the PU nuclei tests. CONCLUSIONS: Polyurethane absorbs and dissipates more energy and is less stiff than either polyethylene or titanium. LEVEL OF EVIDENCE: Basic Science/Biomechanical Study. CLINICAL RELEVANCE: This study characterizes important differences in biomechanical properties of materials that are currently being used for different cervical disc prostheses

Social Marketing

Social marketing is receiving unprecedented focus and support from government, the private sector and charities internationally. Social marketing attempts to educate people in the hope that they will make 'informed'(i.e. healthy) choices regarding diet, lifestyle and health related issues. The effective application of social marketing principles can be complex and controversial. Social marketing planning cannot be reduced to a simple set of actions on a checklist; there is no single strategy for success and strategies that have proved successful with one population may not transfer to other populations. This text will explore the complexities involved in researching, planning and implementing effective social marketing programmes, using illustrative cases from both successful and unsuccessful real-world programmes. The authors provide a critical analysis of the origins of social marketing as a concept and of the claims made by its supporters and detractors in order to highlight what social marketing can and cannot achieve. This is followed by a review of strategic issues that must be considered in developing social marketing programmes, including persuasion resistance, message relevance and message framing. Key themes included in the text are the impact of cultural factors on health-related behaviours, ethical issues and attitudes as a key factor underlying health-related behaviours. The authors introduce concepts, theories and strategies that will aid the development, testing and implementation of social marketing interventions. The book is suitable for both undergraduate and postgraduate students of business and marketing and those studying modules in social marketing

Viral Studies In Pemphigus

Sera from patients with pemphigus. other bullous dermatoses, and various control groups were examined to determine whether paramyxoviruses, particularly SVS and DU, could be isolated. Indirect immunofluorescent tests and virus neutralization tests were employed to determine the incidence of SV5 virus antibody in sera from patients with various dermatoses, and to determine whether antibody to SV5 was related to the antiepithelial antibody associated with pemphigus. The frequency of antibody to SV5 (9%) and DU (11%) virus in sera from patients with pemphigus was not higher than the frequency ot antibodies to SV5 (14%) and DU (17%) in sera of various control groups. The absence of antibodies to 8V5 and DU virus in sera from most patients with pemphigus, the absence of intercellular antiepithelial antibody in sets from dogs and most humans with antibody to SV5 and DU virus, and the absence of correlation of titers in a patient with both types of antibody indicate that SV5 antibody is not functionally related to “pemphigus antibody.” In addition, no SV5, DU, or other hemadsorbing paramyxovirus was isolated from sera of patients with pemphigus. Isolation from blister fluid was not attempted. Infection with SV5, DU, or similar paramyxovirus is probably not usually, if at all, related to the etiology of non-Brazilian pemphigus

To what extent have relaxed eligibility requirements and increased generosity of disability benefits acted as disincentives for employment? A systematic review of evidence from countries with well-developed welfare systems

Background Reductions in the eligibility requirements and generosity of disability benefits have been introduced in several Organisation for Economic Cooperation and Development (OECD) countries in recent years, on the assumption that this will increase work incentives for people with chronic illness and disabilities. This paper systematically reviews the evidence for this assumption in the context of well-developed welfare systems. Method Systematic review of all empirical studies from five OECD countries from 1970 to December 2009 investigating the effect of changes in eligibility requirements or level of disability benefits on employment of disabled people. Results Sixteen studies were identified. Only one of five studies found that relaxed eligibility was significantly associated with a decline in employment. The most robust study found no significant effect. On generosity, eight out of 11 studies reported that benefit levels had a significant negative association with employment. The most robust study demonstrated a small but significant negative association. Conclusion There was no firm evidence that changes in benefit eligibility requirements affected employment. While there was some evidence indicating that benefit level was negatively associated with employment, there was insufficient evidence of a high enough quality to determine the extent of that effect. Policy makers and researchers need to address the lack of a robust empirical basis for assessing the employment impact of these welfare reforms as well as potentially widerpoverty impacts

Multi-color Cavity Metrology

Long baseline laser interferometers used for gravitational wave detection have proven to be very complicated to control. In order to have sufficient sensitivity to astrophysical gravitational waves, a set of multiple coupled optical cavities comprising the interferometer must be brought into resonance with the laser field. A set of multi-input, multi-output servos then lock these cavities into place via feedback control. This procedure, known as lock acquisition, has proven to be a vexing problem and has reduced greatly the reliability and duty factor of the past generation of laser interferometers. In this article, we describe a technique for bringing the interferometer from an uncontrolled state into resonance by using harmonically related external fields to provide a deterministic hierarchical control. This technique reduces the effect of the external seismic disturbances by four orders of magnitude and promises to greatly enhance the stability and reliability of the current generation of gravitational wave detector. The possibility for using multi-color techniques to overcome current quantum and thermal noise limits is also discussed

How Do Collegiate Sport Clubs Achieve Organizational Effectiveness?

A greater understanding of the organizational processes of sport clubs can inform strategies to improve clubs’ organizational effectiveness. This study examined whether sport club capacity and activities influence the organizational effectiveness of collegiate sport clubs. Sport club members (n = 201) completed a questionnaire, with secondary data collected from the university. Regression analysis found club operations, club fiscal responsibility, frequency of club practice, and frequency of competitions significantly, positively predict organizational effectiveness. Comparatively, club human capital and facility quality significantly, negatively predict organizational effectiveness. These results have implications relating to club training, mentorship, resource allocation, and club activities

Spectra and Light Curves of Failed Supernovae

Astronomers have proposed a number of mechanisms to produce supernova explosions. Although many of these mechanisms are now not considered primary engines behind supernovae, they do produce transients that will be observed by upcoming ground-based surveys and NASA satellites. Here we present the first radiation-hydrodynamics calculations of the spectra and light curves from three of these "failed" supernovae: supernovae with considerable fallback, accretion induced collapse of white dwarfs, and energetic helium flashes (also known as type .Ia supernovae).Comment: 33 pages, 14 figure
