Measuring Creativity for Innovation Management
Identifying the extent and nature of the creativity of new products is a key for innovation management. The revised Creative Solution Diagnosis Scale (CSDS) is a 27-item scale based on a theoretical model of functional creativity, consisting of five main criteria: Relevance & Effectiveness, Problematization, Propulsion, Elegance and Genesis. The CSDS offers potential for differentiated assessments of product creativity as part of the larger process of innovation. Non-expert judges rated a series of mousetrap designs using a 30-item version of the CSDS. Confirmatory factor analysis revealed a simple structure that corresponded closely to the a priori theoretical model of functional creativity. The untrained judges were able to use the scale with a high degree of reliability and internal consistency. The scale offers a tool for managing innovation, especially for stimulating creativity and diagnosing the creativity of products

Needs assessment for agricultural development: Practical issues in informal data collection
The growth of Rapid Rural Appraisal (RRA) as an approach to the initial preparation of development projects has had a significant impact on research methodology. It has reflected the shift in development over recent years to listen more to the needs voiced by local people while still allowing development workers to conduct research in spite of budget constraints. RRA could be viewed as just a shift in approach, or as the introduction of a set of new techniques. In practice there is a danger of burdening it with too many expectations and ignoring useful lessons learned from other techniques in the past. The authors have drawn on the extensive field experience within the Natural Resources Institute to assess the strengths and weaknesses of RRA in practice, and to make suggestions for any deficiencies by drawing on elements of older methodologies. Needs Assessment for Agriculture: Practical Issues in Informal Data Collection is designed to provide a practical addition to the materials available to workers in the field as well as to generate discussion amongst those interested in RRA theory

The use of geographical information systems in socio-economic studies
Geographical information systems (GIS) have found wide and growing applications, as digital remote-sensing data and computer technology have become more sophisticated, more easily available and less expensive. NRI recently undertook preliminary research into potential socio-economic applications of GIS. The feasibility of utilizing spatial data, available in GIS, to model socio-economic relationships was examined. It included the following steps: (a) identification of hypothetical relationships between socio-economic variables and location-specific variables; (b) investigation of data sets that might permit the socio-economic variables to be modelled as a function of the spatial phenomena; and (c) a critical assessment of the prospects for modelling socio-economic relationships utilizing GIS data. A number of general issues concerning the availability of suitable data sets, which can constitute a serious constraint to GIS applications were highlighted in the case studies. Recommendations are made concerning how data could be made more amenable to this type of appliction, and the criteria that should be applied in assessing the feasibility of projects involving the use of GIS in socioeconomic studies
A Sustained Dietary Change Increases Epigenetic Variation in Isogenic Mice
Epigenetic changes can be induced by adverse environmental exposures, such as nutritional imbalance, but little is known about the nature or extent of these changes. Here we have explored the epigenomic effects of a sustained nutritional change, excess dietary methyl donors, by assessing genomic CpG methylation patterns in isogenic mice exposed for one or six generations. We find stochastic variation in methylation levels at many loci; exposure to methyl donors increases the magnitude of this variation and the number of variable loci. Several gene ontology categories are significantly overrepresented in genes proximal to these methylation-variable loci, suggesting that certain pathways are susceptible to environmental influence on their epigenetic states. Long-term exposure to the diet (six generations) results in a larger number of loci exhibiting epigenetic variability, suggesting that some of the induced changes are heritable. This finding presents the possibility that epigenetic variation within populations can be induced by environmental change, providing a vehicle for disease predisposition and possibly a substrate for natural selection.This work was supported by the Australian Research Council (DP0771859) and the National Health and Medical Research Council (#459412, #635510)

Low-Cost High-Pressure Hydrogen Generator
Electrolysis of water, particularly in conjunction with renewable energy sources, is potentially a cost-effective and environmentally friendly method of producing hydrogen at dispersed forecourt sites, such as automotive fueling stations. The primary feedstock for an electrolyzer is electricity, which could be produced by renewable sources such as wind or solar that do not produce carbon dioxide or other greenhouse gas emissions. However, state-of-the-art electrolyzer systems are not economically competitive for forecourt hydrogen production due to their high capital and operating costs, particularly the cost of the electricity used by the electrolyzer stack. In this project, Giner Electrochemical Systems, LLC (GES) developed a low cost, high efficiency proton-exchange membrane (PEM) electrolysis system for hydrogen production at moderate pressure (300 to 400 psig). The electrolyzer stack operates at differential pressure, with hydrogen produced at moderate pressure while oxygen is evolved at near-atmospheric pressure, reducing the cost of the water feed and oxygen handling subsystems. The project included basic research on catalysts and membranes to improve the efficiency of the electrolysis reaction as well as development of advanced materials and component fabrication methods to reduce the capital cost of the electrolyzer stack and system. The project culminated in delivery of a prototype electrolyzer module to the National Renewable Energy Laboratory for testing at the National Wind Technology Center. Electrolysis cell efficiency of 72% (based on the lower heating value of hydrogen) was demonstrated using an advanced high-strength membrane developed in this project. This membrane would enable the electrolyzer system to exceed the DOE 2012 efficiency target of 69%. GES significantly reduced the capital cost of a PEM electrolyzer stack through development of low cost components and fabrication methods, including a 60% reduction in stack parts count. Economic analysis indicates that hydrogen could be produced for 0.05/kWh by the lower-cost PEM electrolyzer developed in this project, assuming high-volume production of large-scale electrolyzer systems
Reflecting back and forwards: The ebb and flow of peer-reviewed reflective practice research in sport
Researchers in sport have claimed that reflective practice is important for competent practice. Evidence supporting this claim is sparse, highly theoretical and located within a variety of domains. The aim of this study was to assimilate and analyse the last 12 years of reflective practice literature within the sport domain in order to identify new areas of inquiry, emerging trends with regard to findings or methodology, and to identify implications for future research and practice. A sample of 68 papers published between 2001 and 2012 was examined, and investigated for the research locations, data collection methods utilised, and the professions and communities involved. The paper concludes with some suggestions for future research
Choreography, controversy and child sex abuse: Theoretical reflections on a cultural criminological analysis of dance in a pop music video
This article was inspired by the controversy over claims of ‘pedophilia!!!!’ undertones and the ‘triggering’ of memories of childhood sexual abuse in some viewers by the dance performance featured in the music video for Sia’s ‘Elastic Heart’ (2015). The case is presented for acknowledging the hidden and/or overlooked presence of dance in social scientific theory and cultural studies and how these can enhance and advance cultural criminological research. Examples of how these insights have been used within other disciplinary frameworks to analyse and address child sex crime and sexual trauma are provided, and the argument is made that popular cultural texts such as dance in pop music videos should be regarded as significant in analysing and tracing public perceptions and epistemologies of crimes such as child sex abuse
Variation in C - reactive protein response according to host and mycobacterial characteristics in active tuberculosis
BACKGROUND: The C - reactive protein (CRP) response is often measured in patients with active tuberculosis (TB) yet little is known about its relationship to clinical features in TB, or whether responses differ between ethnic groups or with different Mycobacterium tuberculosis (M.tb) strain types. We report the relationship between baseline serum CRP prior to treatment and disease characteristics in a metropolitan population with TB resident in a low TB incidence region. METHODS: People treated for TB at four London, UK sites between 2003 and 2014 were assessed and data collected on the following characteristics: baseline CRP level; demographics (ethnicity, gender and age); HIV status; site of TB disease; sputum smear (in pulmonary cases) and culture results. The effect of TB strain-type was also assessed in culture-positive pulmonary cases using VNTR typing data. RESULTS: Three thousands two hundred twenty-two patients were included in the analysis of which 72 % had a baseline CRP at or within 4 weeks prior to starting TB treatment. CRP results were significantly higher in culture positive cases compared to culture negative cases: median 49 mg/L (16-103 mg/L) vs 19 mg/L (IQR 5-72 mg/L), p = <0.001. In those with pulmonary disease, smear positive cases had a higher CRP than smear negative cases: 67 mg/L (31-122 mg/L) vs 24 mg/L (7-72 mg/L), p < 0.001. HIV positive cases had higher baseline CRPs than HIV negative cases: 75 mg/L (26-136 mg/L) vs 37 mg/L (10-88 mg/L), p <0.001. Differing sites of disease were associated with differences in baseline CRP: locations that might be expected to have a high mycobacterial load (e.g. pulmonary disease and disseminated disease) had a significantly higher CRP than those such as skin, lymph node or CNS disease, where the mycobacterial load is typically low in HIV negative subjects. In a multivariable log-scale linear regression model adjusting for host characteristics and M.tb strain type, infection with the East African Indian strain was associated with significantly lower baseline-CRP (fold-change in CRP 0.51 (0.34-0.77), p < 0.01). CONCLUSIONS: Host and mycobacterial factors are strongly associated with baseline CRP response in tuberculosis. This analysis suggests that there are important differences in innate immune response according to ethnicity, Mtb strain type and site of disease. This may reflect differing mycobacterial loads or host immune responses
Development and initial validation of an instrument to measure students' learning about systems thinking: the affective domain
The purpose of this study was to develop and validate a new, theoretically-based scale that would assess students' learning about systems thinking in relation to the affective domain in systems engineering education. Students' learning of systems thinking in the affective domain deal with emotions, feelings and valuing the related cognitive systems thinking aspects. It is characterized by belief in the power of systems thinking to enable them to develop superior engineered products and systems. This paper describes the psychometric properties of the scale as the basis for future use with a target population of engineering students. It provides the results of an instrument test analysis of data collected from a representative set of the target audience of the instrument. The participants in this study were 180 undergraduate engineering students who enrolled in a systems engineering course. Exploratory factor analysis of the scale for the sample yielded factors largely consistent with conceptualization and construction of the subscales. Confirmatory factor analysis of the scale also supports the initial factor structure. The results suggest that this instrument may be useful to researchers and practitioners interested in measuring systems thinking in engineering students, particularly in the affective domain
