AbstractObjectiveTo analyse the relationship between different heart rate variability indices, resting heart rate, and cardiovascular markers in adolescents.MethodsA cross-sectional study was carried out with information from an ongoing cohort study. The sample was composed of 99 adolescents who complied with the following inclusion criteria: aged between 11 and 14 years; enrolled in a school unit of elementary education; absence of any known diseases; no drug consumption; and a formal consent signed by the parents or legal guardians. Weight, height, heart rate variability, lipid profile, inflammatory markers, blood pressure, resting heart rate, intima-media thickness, blood flow, and trunk fatness were measured. Partial correlation and linear regression (expressed by β and 95% confidence intervals [95%CI]) analyses were used to analyse the relationships between the variables.ResultsIn the linear regression analysis, even after adjustments for sex, age, trunk fatness, and somatic maturation, parasympathetic activity presented significant correlations with maximum carotid artery blood flow (β=−0.111 [95%CI=−0.216; −0.007]), systolic blood pressure (β=−0.319 [95%CI=−0.638; −0.001]), and resting heat rate (β=−0.005 [95%CI=−0.009; −0.002]).ConclusionParasympathetic activity at rest is inversely related to maximum and minimum blood flow, triacylglycerol levels, and systolic blood pressure. These findings suggest that heart rate variability has the potential to discriminate pre-pubertal adolescents at increased risk.

AbstractCatalysts play a significant role in clean renewable hydrogen fuel generation through water splitting reaction as the surface of most semiconductors proper for water splitting has poor performance for hydrogen gas evolution. The catalytic performance strongly depends on the atomic arrangement at the surface, which necessitates the correlation of the surface structure to the catalytic activity in well-controlled catalyst surfaces. Herein, we report a novel catalytic performance of simple-synthesized porous NiO nanowires (NWs) as catalyst/co-catalyst for the hydrogen evolution reaction (HER). The correlation of catalytic activity and atomic/surface structure is investigated by detailed high resolution transmission electron microscopy (HRTEM) exhibiting a strong dependence of NiO NW photo- and electrocatalytic HER performance on the density of exposed high-index-facet (HIF) atoms, which corroborates with theoretical calculations. Significantly, the optimized porous NiO NWs offer long-term electrocatalytic stability of over one day and 45 times higher photocatalytic hydrogen production compared to commercial NiO nanoparticles. Our results open new perspectives in the search for the development of structurally stable and chemically active semiconductor-based catalysts for cost-effective and efficient hydrogen fuel production at large scale.
Estimating Yield Losses Due to Barley Yellow Dwarf on Winter Wheat in Kansas Using Disease Phenotypic Data
Authors: Gaunce Genna M. , Bockus William W. 
Published: February 2015

Barley yellow dwarf (BYD) is one of the most important wheat diseases in the state of Kansas. Despite the development of cultivars with improved resistance to BYD, little is known about the impact that this resistance has on yield loss from the disease. The intent of this research was to estimate yield loss in winter wheat cultivars in Kansas due to BYD and quantify the reduction in losses associated with resistant cultivars. During seven years, BYD incidence was visually assessed on numerous winter wheat cultivars in replicated field nurseries. When grain yields were regressed against BYD incidence scores, negative linear relationships significantly fit the data for each year and for the combined dataset covering all seven years. The models showed that, depending upon the year, 19–48% (average 33%) of the relative yields was explained by BYD incidence. For the combined dataset, 29% of the relative yield was explained by BYD incidence. The models indicated that cultivars showing the highest disease incidence that year had 25–86% (average 49%) lower yield than a hypothetical cultivar that showed zero incidence. Using the models, the moderate level of resistance in the cultivar Everest was calculated to reduce yield loss from BYD by about 73%. Therefore, utilizing visual BYD symptom evaluations in Kansas coupled with grain yields is useful to estimate yield loss from the disease. Accepted for publication 1 December 2014.

Mutual dependence and the “Goldilocks group”: exploring service user dependency on mutual aid recovery groups
Authors: Parkman Thomas James , Lloyd Charlie 
Published: February 2015

Purpose
– The purpose of this paper is to explore the theme of dependence on mutual aid identified in a previous paper. It is a theme which to date, has had very little empirical attention, especially in a UK context.

Design/methodology/approach
– A phenomenological approach was adopted. Interviews with service users, mentors and professional staff involved with the Learning to Live Again project were undertaken over a ten-month period of data collection. Thematic analysis was used to analyse the data.

Findings
– It was found that service users with very little access to recovery capital or social support are at risk of developing a dependency on mutual aid. Dependence seemed to manifest itself in two different forms – those that over engaged with the project and those that under engaged with the project. Consequently, there were a cohort of service users identified that seemed to strike a balance with the project and their life outside the project that was “just right”. They were referred to as the “Goldilocks group”.

Originality/value
– This paper explored a theme which has had very little attention paid to it. The theme of dependence on mutual aid will raise the awareness of such a threat, thus helping to identify those in treatment most at risk of developing dependency on mutual aid, thus detrimentally impacting on mental wellbeing.

Authors: Soublière Jean-François , Cloutier Charlotte 
Published: February 2015

Subject areaPublic sector management, stakeholder management, collaboration and strategy.Study level/applicabilityUndergraduate (final-year) or master's-level students (Master in Public Administration, Master in Management). Designed for courses in nonprofit management, public administration and/or international development. Can also be used in any course, such as strategic management, sustainable development or corporate social responsibility, that covers stakeholder theory, or stakeholder management as a topic.Case overviewDecentralization has changed the way core services are delivered to local populations in sub-Saharan Africa. This in turn has forced nongovernmental organizations, international aid agencies, corporations and other development partners to change the way they engage with government in their shared efforts to help improve the living conditions of people living under the threshold of poverty in this and other parts of the world. This modular ethnographic teaching case uses the specific example of the water sector in Malawi to help highlight the complexity of multiple stakeholder relations in an international development context.Expected learning outcomesUpon completion of this case, students should be able to: identify and understand the different goals and issues that individual stakeholders in cross-sector partnerships are dealing with; identify and understand the power/control dynamics at play in these relationships; analyse the advantages and disadvantages associated with different ways of coordinating multi-stakeholder partnerships; and develop recommendations for structuring multi-stakeholder relationships in developing and emerging markets that balance efficient service provision with concern for individual stakeholder priorities.Supplementary materialsTeaching Notes are available for educators only.

Enhancing teaching relationships through therapeutic use of self
Authors: Williams Bronwen 
Published: February 2015

Purpose
– The purpose of this paper is to examine how the skills involved in building therapeutic relationships, especially the therapeutic use of self, in clinical work can transfer in to teaching, making reference to the supporting education theory.

Design/methodology/approach
– A review of relevant education and health literature was undertaken.

Findings
– Mental health practitioners’ skills transfer with good effect to the classroom, therefore clinicians who deliver teaching to mental health colleagues can be seen to be highly effective in promoting excellent learning environments. The teacher, and their teaching, needs to be student focused in the same way that the clinician needs to be patient centred to build the best possible relationships to support development and change.

Originality/value
– The therapeutic relationship is a fundamental element of mental health work and similarly, the relationships that the teachers develop with students are essential to the promotion of learning environments. However, what creates the teacher-student relationship has been little examined in the literature and this paper suggests that the core elements of the therapeutic relationship, especially therapeutic use of self, transfer to the teaching relationship to impact on learning for mental health staff.

Authors: Zheng Haichao , Hung Jui-Long , Lin Zhangxi , Wu Jing 
Published: February 2015

Purpose– The purpose of this paper is investigating the value of service guarantee (SG) program in Service e-Commerce (SeC) which is one resolution to promote service transactions. SeC is emerging as a booming form of e-commerce where various services are contracted, managed, sold and even delivered via the Internet. However, the uncertainty of service quality and the heterogeneity of buyer preferences have been major challenges to sustainable development of SeC.Design/methodology/approach– This study uncovered the value of SG in SeC by empirically analyzing the data collected fromzhubajie.com, a well-known service e-marketplace in China, to classify the service providers, to indentify the predictors for SG subscription and to study the effects of SG on service providers’ business performance and service quality.Findings– The authors found that the distribution of service provisions is diversified in terms of low-success, mid-success and high-success providers, while proactive or high ability-ranking providers consistently tend to subscribe to SG program. The study revealed that SG has diverse effects on business performance for low-success and mid-success providers. For high-success providers, it seems to not be an effective choice for transaction promotion. Finally, the results showed that SG marginally improved service quality.Practical implications– This research provides some practical implications for SeC markets to improve SG program. In addition, the results also help service providers to understand the value of SG in depth.Originality/value– This article extended the research of SG from the traditional offline market to the online market, as with SeC, in which transactions are conducted without face to face contact.

Synthesis and characterisation of the flame retardant properties and corrosion resistance of Schiff’s base compounds incorporated into organic coating
Authors: Abd El-Wahab H. 
Published: February 2015

Purpose
– This paper aims to report on the synthesis and characterisation of new flame retardants and anticorrosive additives based on Schiff’s base compounds, which were added physically to organic coating.

Design/methodology/approach
– Flame retardants are incorporated into polymeric materials either as additives or as reactive materials. Additive-type flame retardants are widely used by incorporating into polymeric materials by physical means. In this research, Schiff’s base (azomethine) compounds are added physically to alkyd paint as flame-retardant additives. Elemental analysis, infrared spectroscopy and proton nuclear magnetic resonance spectroscopy were used to characterise the structure of the prepared Schiff’s base compounds. Thermal gravimetric analysis was used to evaluate their thermal stability. Experimental coatings were manufactured on a laboratory scale, and then applied by brush on wood and steel panels.

Findings
– Results of an oxygen index value indicated that alkyd paints containing Schiff’s base compounds as additives exhibit very good flame-retardant effects. Also the physical, mechanical and corrosion resistance properties were studied to evaluate the drawbacks of the additives. The additives did not affect the flexibility of the paint formula. The gloss and the impact strength were decreased by the additives, but the hardness, adhesion and corrosion resistance were significantly improved by these additives.

Research limitations/implications
– Alkyd resins are the most extensively used synthetic polymers in the coating industry. Nitrogen compounds are a small but rapidly growing group of flame retardants which are in the focus of public interest concerning environment-friendly flame retardants. So, the focus of this study is on Schiff’s base compounds as flame retardants and anticorrosive additives for alkyd resins to assess their applicability.

Practical implications
– Schiff’s base compounds can be used as new additives in paint formulations to improve the flame-retardant and corrosion properties.

Originality/value
– In recent years, there has been considerable interest in the nitrogen-based family of materials because they not only have a wide range of thermal and chemical stabilities, but can also provide improved thermal and flame-retardant properties to polymers. The present paper reports on the synthesis and characterisation of Schiff’s base compounds and their performance in alkyd resin coatings.
Preparation and characterization of in situ electrospun ZnS nanoparticles/PPV nanofibers
Authors: Xin Yi , Jiang Zijiang , Li Wenwen , Huang Zonghao , Wang Cheng 
Published: February 2015

Purpose
– This paper aimed to prepare a kind of ZnS nanoparticles/poly(phenylene vinylene) (PPV) nanofibre and investigate its properties. Because the ZnS nanoparticles are important optoelectronic materials, their incorporation into one-dimensional (1D) nanoscale polymer matrices should be a meaningful subject for electrospinning.

Design/methodology/approach
– ZnS/PPV composite nanofibres with an average diameter of 600 nm were successfully prepared by a combination of the in situ method and electrospinning technique. The nanofibres were electrospun from Zn(CH3COO)2·2H2O and PPV precursor composite solution, and the ZnS/PPV fibres were obtained by exposure of the electrospun fibres to H2S gas to prepare ZnS nanoparticles in situ. Such fibres were characterised using X-ray Diffraction (XRD), Fourier transform infrared, transmission electron microscope (TEM), scanning electron microscope and photoluminescence (PL). The photoelectric properties of the fibres obtained were also investigated.

Findings
– XRD patterns proved that ZnS nanocrystals generated in the composite nanofibres. The TEM image showed that the nanocrystals were homogeneously dispersed in the nanofibres. The PL spectrum of ZnS/PPV composite nanofibres exhibited a blue shift relative to the PPV nanofibres. I-V curve of the single nanofibre device under 5.76 mW/cm2 light illumination showed that the composite nanofibres have good photoelectric properties.

Research limitations/implications
– The comparisons of advantages between ZnS/PPV nanofibres with similar nanofibres will be further expanded in a later research.

Practical implications
– Results demonstrate the promise of these novel nanostructures as ultraminiature photodetectors with the potential for integration into future hybrid nanophotonic devices and systems.

Originality/value
– The integration of inorganic semiconductor nanoparticles into organic conjugated polymers leads to composite materials with unique physical properties and important application potential. In this work, ZnS nanoparticles were introduced into PPV by an in situ method, so as to obtain a kind of novel 1D nanomaterials with good photoelectric properties.
