Published: January 2015

AbstractExpanding the range of supercapacitor operation to temperatures above 100°C is important because this would enable capacitors to operate under the severe conditions required for next-generation energy storage devices. In this study, we address this challenge by the fabrication of a solid-state supercapacitor with a proton-conducting Sn0.95Al0.05H0.05P2O7 (SAPO)-polytetrafluoroethylene (PTFE) composite electrolyte and a highly condensed H3PO4 electrode ionomer. At a temperature of 200°C, the SAPO-PTFE electrolyte exhibits a high proton conductivity of 0.02 S cm−1 and a wide withstanding voltage range of ±2 V. The H3PO4 ionomer also has good wettability with micropore-rich activated carbon, which realizes a capacitance of 210 F g−1 at 200°C. The resulting supercapacitor exhibits an energy density of 32 Wh kg−1 at 3 A g−1 and stable cyclability after 7000 cycles from room temperature to 150°C.
Lifecourse Adiposity and Blood Pressure Between Birth and 17 Years Old

BACKGROUND
Childhood obesity creates a predisposition to develop adult hypertension and diabetes. We have identified distinct childhood adiposity trajectories associated with increased insulin resistance in early adolescence. Our aim was to investigate the relationship between these adiposity trajectories with childhood blood pressure (BP) development.

METHODS
Adiposity trajectories were previously developed by semiparametric modeling using serial anthropometry from birth to age 14 from the West Australian Pregnancy Cohort. The association between these trajectories and the prevalence of hypertension and prehypertension in 17 year olds was assessed by logistic regression. The relationship between adiposity trajectories and lifecourse BP was then assessed using linear mixed modeling.

RESULTS
The study includes 1,023 adolescents with BP measured at age 17 years. Three of 7 childhood adiposity trajectories (with accelerating adiposity) previously related to increased insulin resistance were associated with an increased risk of 17-year-old prehypertension or hypertension, compared to a referent trajectory of “stable average adiposity” (odds ratio (OR) = 2.9, P = 0.007; OR = 3.5, P &lt; 0.001; and OR = 1.8, P = 0.041). One decelerating adiposity trajectory from high birth size was associated with significant interactions with age terms (P values = 0.025–0.084 and 0.011–0.027), indicating an altered slope and therefore, relative decline in lifecourse BP compared to the reference adiposity trajectory.

CONCLUSIONS
Adiposity trajectories (which comprise 27% of the population) were associated with an increased risk of hypertension/prehypertension in adolescence. Higher BP was detectable as early as 3 years old. Consequently, targeting fat loss (catch-down growth) in the preschool years may prevent the development of hypertension and related metabolic disorders.
Concentration of Particulate Platinum-Group Minerals during Magma Emplacement; a Case Study from the Merensky Reef, Bushveld Complex
Authors: Hutchinson David , Foster Jeffrey , Prichard Hazel , Gilbert Sarah 
Published: January 2015

AbstractThe petrology, mineralogy and geochemistry of a section of the Merensky Reef at Bafokeng Rasimone Platinum Mine (BRPM) are described. A model for the formation of platinum-group minerals (PGM), sulphide and chromitite is proposed that explains the stratigraphic relationships observed in the Merensky Reef, both at BRPM and at other locations in the Bushveld Complex. To achieve this it is necessary to understand platinum-group element (PGE) behaviour in naturally occurring mafic systems and for this reason comparisons are drawn from core TN207 through the Platreef at Tweefontein. The common link between the Platreef and Merensky Reef is the presence of unusually high concentrations of As, Sb, Bi and Te that promote the crystallisation of semi-metal bearing PGM from sulphide liquids. Under conditions of increasing semi-metal contamination, Pt is the first PGE to be extracted from a sulphide liquid followed by Rh, Ru, Os and Ir. While some Pd is released to form Pd-PGM much of it remains within the Ni-rich sulphide phase that crystallizes to form pentlandite. A critical aspect is the timing of their introduction into the magmatic system. For the Merensky magmas, contamination occurred predominantly within a staging chamber owing to wall-rock interaction with Transvaal sediments. This led to the formation of sulphide liquids that captured PGE and, ultimately, the crystallization of Pt- and Ru-PGM. The extreme enrichment in PGE and the high Pt/Pd ratios in the Merensky chromitites are attributed to density-driven concentration of PGM transported by magmas displaced from a staging chamber. Emplacement of these magmas into the Bushveld Complex resulted in thermo-mechanical erosion of the floor and deposition of chromites + sulphides + PGM. In places, these assemblages collected in sedimentary-like scour channels. In the Platreef, contamination occurred largely after magma emplacement owing to interaction with the local Transvaal sediments. As a result, mechanical separation of PGM did not occur and most PGM remain spatially associated with their original sulphide hosts.The Merensky Reef is a prime example of highly efficient PGE concentration resulting from mechanical processes, whereas the Platreef is a prime example of highly efficient PGE removal from sulphide liquids in response to extreme contamination by semi-metals.
Eco-bio-social research on community-based approaches for Chagas disease vector control in Latin America
Authors: Gürtler Ricardo E. , Yadon Zaida E. 
Published: January 2015

Abstract
This article provides an overview of three research projects which designed and implemented innovative interventions for Chagas disease vector control in Bolivia, Guatemala and Mexico. The research initiative was based on sound principles of community-based ecosystem management (ecohealth), integrated vector management, and interdisciplinary analysis. The initial situational analysis achieved a better understanding of ecological, biological and social determinants of domestic infestation. The key factors identified included: housing quality; type of peridomestic habitats; presence and abundance of domestic dogs, chickens and synanthropic rodents; proximity to public lights; location in the periphery of the village. In Bolivia, plastering of mud walls with appropriate local materials and regular cleaning of beds and of clothes next to the walls, substantially decreased domestic infestation and abundance of the insect vector Triatoma infestans. The Guatemalan project revealed close links between house infestation by rodents and Triatoma dimidiata, and vector infection with Trypanosoma cruzi. A novel community-operated rodent control program significantly reduced rodent infestation and bug infection. In Mexico, large-scale implementation of window screens translated into promising reductions in domestic infestation. A multi-pronged approach including community mobilisation and empowerment, intersectoral cooperation and adhesion to integrated vector management principles may be the key to sustainable vector and disease control in the affected regions.

AbstractBackgroundSearching for similar compounds in a database is the most important process for in-silico drug screening. Since a query compound is an important starting point for the new drug, a query holder, who is afraid of the query being monitored by the database server, usually downloads all the records in the database and uses them in a closed network. However, a serious dilemma arises when the database holder also wants to output no information except for the search results, and such a dilemma prevents the use of many important data resources.ResultsIn order to overcome this dilemma, we developed a novel cryptographic protocol that enables database searching while keeping both the query holder’s privacy and database holder’s privacy. Generally, the application of cryptographic techniques to practical problems is difficult because versatile techniques are computationally expensive while computationally inexpensive techniques can perform only trivial computation tasks. In this study, our protocol is successfully built only from an additive-homomorphic cryptosystem, which allows only addition performed on encrypted values but is computationally efficient compared with versatile techniques such as general purpose multi-party computation. In an experiment searching ChEMBL, which consists of more than 1,200,000 compounds, the proposed method was 36,900 times faster in CPU time and 12,000 times as efficient in communication size compared with general purpose multi-party computation.ConclusionWe proposed a novel privacy-preserving protocol for searching chemical compound databases. The proposed method, easily scaling for large-scale databases, may help to accelerate drug discovery research by making full use of unused but valuable data that includes sensitive information.

Published: January 2015

Purpose
– The purpose of this paper is to investigate how service managers perceive their service prior to, and following the delivery of a cognitive-behavioural therapy (CBT) anger management group for individuals with an intellectual disability.

Design/methodology/approach
– Telephone interviews were conducted with seven service managers, before and after a CBT group intervention. The interviews were recorded, transcribed and analysed using thematic analysis to identify common and/or contrasting themes.

Findings
– Before the intervention took place managers observed a lack of consistency in how their staff dealt with challenging incidents and the serious consequences these incidents had for service users as well as staff. They spoke about the importance of multi-disciplinary working and good quality staff selection, support and training. After the group intervention managers commented on a positive “spilling-out effect” whereby the whole organisation was influenced by the intervention, a greater willingness on the part of service users to talk about their problems, and an increased confidence in the staff members who had co-facilitated the group work.

Research limitations/implications
– The implications of the themes raised are discussed and recommendations for further research are suggested.

Originality/value
– This research provides a unique contribution of managers’ views and insight into how hosting a CBT group intervention impacted on their wider services.
How can mental health clinicians, working in intellectual disability services, meet the spiritual needs of their service users?
Authors: Loynes Benjamin , O'Hara Jean 
Published: January 2015

Purpose
– The purpose of this paper is to identify approaches that mental health clinicians, working in intellectual disability services, can adopt to ensure the spiritual needs of their service users are met.

Design/methodology/approach
– A narrative literature review examining original research, expert opinion pieces and book chapters was undertaken. To broaden the perspective of the paper, publications from different academic areas were reviewed including intellectual disabilities, mental health, neurodevelopmental disorders, general health and spirituality literature.

Findings
– The main principles of spiritual assessment tools from the general health literature can be applied to this group. However, the literature would suggest that certain approaches are of particular importance in intellectual disabilities mental health including advocating for service users to attend the religious services they wish to and working collaboratively with families and carers when addressing spiritual issues.

Research limitations/implications
– The question of how to meet the spiritual needs of people with autism and severe intellectual disability is a neglected research area. Research examining the spiritual needs of service users with intellectual disabilities, on mental health inpatient units, is also needed as well as a review of whether spiritual needs are being met in current person-centred care plans.

Originality/value
– No published literature review was identified that specifically addressed the question of how mental health clinicians should approach the spiritual needs of their service users.
The might of the brand
Authors: Beneke Justin , Trappler Emma 
Published: January 2015

Purpose
– This study examined the influence of supermarket brand name on the perceived quality of its private label merchandise. The purpose of this paper is to determine whether the fascia brand of a retail chain has the power to positively or negatively skew prevailing opinions concerning the quality of its own merchandise range, beyond the set of product-specific intrinsic benefits.

Design/methodology/approach
– A within-subject two-phase research design was adopted, intially using an experimental approach and thereafter modeling the cognitive effect with the inclusion of a moderator variable (brand interaction). Paired sample t-tests were used to assess differences in mean ratings and partial least squares analysis was implemented in order to test the hypothesized relationships.

Findings
– In the experiment phase, both products were rated equally at the outset in unsighted conditions, however, ratings diverged when brand name was introduced. Here, the high-end private label brand was scored considerably better than in its unsighted condition, while the low-end brand suffered a marginal decline in rating. In the modeling phase, two iterations of the conceptual model were run, considering the high-end and low-end brands seperately. The results were mutually reinforcing. A strong relationship, significant at the one percent level, was found to exist between brand name and perceived quality for both the lower- and higher-end brands, whereas no moderation effect was found to exist. This suggests that entrenched views of the brand strongly determine the perceived quality thereof, with operational and day-to-day fluctuations having little bearing on this.

Research limitations/implications
– This study focusses solely on South Africa, an emerging market within the BRICS consortium. To this end, the results are not transferable to other markets. The context of the study pitted a top tier retail brand against a mid tier retail brand. In accordance with this eventuality, lower income consumers, and retail chains catering to this market segment, do not constitute components of this particular study.

Originality/value
– While the relationship between store image and perceived quality of private label merchandise is well documented, this study considers the effect through an experimental design. Here, perceived quality was measured both with and without brand cues evident. Thus, the results are likely to be more accurate than those acquired through strictly survey research. As a defining feature, the study points to the brand name as being a supremely powerful extrinsic cue, and hinting at the fact that it is long term influences that create a distinct brand aura, with these being largely undisturbed by short term fluctuations.
Reducing food waste: an investigation on the behaviour of Italian youths
Authors: Principato Ludovica , Secondi Luca , Pratesi Carlo Alberto 
Published: January 2015

Purpose– The purpose of this paper is to assess the knowledge of youths concerning food waste as well as to identify factors that influence changes in behaviour concerning food wasted and planning shopping for preventing it.Design/methodology/approach– The data used were collected from a sample of 233 students at Roma-Tre University in Italy. Probit models were specified to identify factors affecting food waste reduction in both pre-shopping and consumption phases.Findings– Results show that the more aware youths are concerning food waste, the more likely they are to reduce leftovers. In contrast, the concern about food freshness increases waste. A greater awareness of the consequences of food wasted increases the likelihood that youths will make a shopping list.Research limitations/implications– The main limitation of the study can be found in the non-probabilistic sampling design used for the collection of data.Practical implications– This study provides information for both social marketers and policy makers. New educational campaigns against food waste should be carried out by providing them with a realistic perception of food waste as well as by teaching young consumers how to recognize the level of freshness of food.Originality/value– This study provides a first insight of the factors that influence food waste reduction as well as the habit of making a shopping list from an individual perspective.

Authors: Luan Jiang , Chen Jian-cheng , He Zhong-wei , Li Qiang , Qiu Huanguang 
Published: January 2015

Purpose– Education plays an important role in improving Chinese rural laborers’ non-farm incomes. However, in Chinese western rural area, the level of return to education is very low due to the underdeveloped economy and the condition of the education system. For improving the schooling returns level, Chinese central government is paying great attention to the condition of education in the rural western area. To date, no research has examined what educational style is more favorable for improving western rural laborers’ non-farm incomes. To answer this question, the purpose of this paper is to compare the treatment effect of high school education and secondary vocational education on their non-farm incomes. That will provide significant evidence for the government to carry out educational policy.Design/methodology/approach– Base on the Mincer model, several methods is used to estimate the average return to a year education on western rural labors’ non-farm income, including OLS, IV and Heckman tow-steps method, to accounting for the ability endogenous and self-selection bias. And the propensity score matching method is used in estimate the treatment effects of high school education and secondary vocational education.Findings– The results from Mincer model showed that the schooling returns in Chinese western rural area were estimated to range from 2.7 to 3.9 percent, that were lower than the average levels in Chinese whole rural area that are estimated in the other recent studies. By using propensity score matching to roll out the heterogeneous bias, show that the treatment effect from high school education was higher than that from secondary vocational education, indicating that the secondary vocational education is better.Originality/value– Studies concerning the causal relationship between schooling (high school education and secondary vocational education) and non-farm earnings in the western region of China remain very limited, even empty. This paper will make an update contribution to the literature in the area of education earnings in China.
Examining the impact of negative, user-generated content on stakeholders
Authors: Haigh Michel M , Wigley Shelley 
Published: January 2015

Purpose
– The purpose of this paper is to (n=472) examine how negative, user-generated content on Facebook impacts stakeholders’ perceptions of the organization.

Design/methodology/approach
– At Phase 1, stakeholders’ perceptions about the organization – public relationship, corporate social responsibility, attitude toward the organization, and reputation of the organization were assessed. A week later, at Phase 2, participants were exposed to negative Facebook comments. This study employed the theory of inoculation as a way to bolster stakeholders’ attitudes to protect against attitude shift following exposure to negative, user-generated comments.

Findings
– Paired sample t-tests indicate stakeholders’ perceptions of the organization – public relationship and corporate social responsibility significantly decrease after stakeholders read negative, user-generated content. The pattern of means supports the idea inoculation can prevent against attitude shift.

Practical implications
– Strategic communication professionals should be aware of the impact negative posts can have and develop a strategy to respond to negative comments on Facebook.

Originality/value
– There is limited experimental research examining the impact of negative Facebook posts on stakeholders. It extends current literature and provides practitioners with some guidance on the impact of negative, user-generated content.
Financial communication in initial public offerings
Authors: Tong Suk-Chong 
Published: January 2015

Purpose– The purpose of this paper is to propose a model of financial communication to investigate the process of communicating risk signals between listed companies and their individual retail investors in initial public offerings (IPOs).Design/methodology/approach– A survey study on individual IPO investors (n=212) in the Hong Kong Stock Exchange was conducted to examine how risk estimates of individual retail investors were affected by three factors of financial communication, namely organizational trust, organizational reputation and investors’ trust in the media specialists. Structural equation modeling analysis was conducted.Findings– Respondents’ perceived risks of below-target returns and perceived risks of losses of principals were significantly affected by their perceived market risks. Respondents relied significantly on organizational trust to estimate their amounts of target returns and mitigate their perceived risks of losses of principals. Organizational reputation, which could be possibly reinforced by respondents’ trust in the media specialists, could enhance organizational trust.Practical implications– Corporate communications practitioners should pay attention to the effect of perceived market risk on risk estimate. As organizational trust is a significant precondition of risk taking in IPOs, practitioners should rethink the effectiveness of financial communication in which organizational trust, organizational reputation and investors’ trust in the media specialists are interrelated.Originality/value– There is a lack of research in financial communication from the organization-stakeholders perspective. This paper conceptualizes financial communication and provides insights to both scholars and practitioners in corporate communications on how significant factors of financial communication affect risk estimate in the financial market.
