Authors: Liu Hao , Zhang Yujuan , Zhang Shengmao , Chen Yanfen , Zhang Pingyu , Zhang Zhijun 
Published: April 2015

Purpose
– The purpose of this paper is synthesis of oil-soluble non-spherical nanoparticles modified with free phosphorus and sulphur modifier and investigation of their tribological properties as environment-friendly lubricating oil additives.

Design/methodology/approach
– To study the effect of morphology of nanoparticles on their tribological properties, rice-like CuO nanoparticles were synthesized. To improve the solubility of CuO nanoparticles in organic media, the in-situ surface modification method was used to synthesize these products. The morphology, composition and structure of as-synthesized CuO nanoparticles were investigated by means of transmission electron microscopy, X-ray powder diffraction, thermogravimetric analysis and Fourier transform infrared spectrometry. The tribological properties of as-synthesized CuO nanoparticles as an additive in liquid paraffin (LP) were evaluated with a four-ball tribometer. The morphology and elemental composition of worn steel ball surfaces were analysed by X-ray photoelectron spectroscopy.

Findings
– It has been found that as-synthesized CuO nanoparticles with rice-like morphology have an average size of 7 and 15 nm along the shorter axle and longer axle, respectively, and can be well-dispersed in LP. Tribological properties evaluation results show that as-synthesized CuO nanoparticles as additives in LP show good friction-reducing, anti-wear and load-carrying capacities, especially under a higher normal load.

Originality/value
– Oil-soluble rice-like CuO nanoparticles without phosphorus and sulphur were synthesized and their tribological properties as lubricating oil additives were also investigated in this paper. These results could be very helpful for application of CuO nanoparticles as environment-friendly lubricating oil additives, owing to their free phosphorus and sulphur elements characteristics.
Synthesis and tribological properties of oil-soluble copper nanoparticles as environmentally friendly lubricating oil additives
Authors: Zhang Yujuan , Xu Yaohua , Yang Yuangbin , Zhang Shengmao , Zhang Pingyu , Zhang Zhijun 
Published: April 2015

Purpose
– The purpose of this paper is to synthesize oil-soluble copper (Cu) nanoparticles modified with free phosphorus and sulfur modifier and investigate its tribological properties as environment-friendly lubricating oil additives.

Design/methodology/approach
– To improve the anti-oxidation properties of these nanoparticles, two kinds of surface modifiers, oleic acid and oleylamine were used simultaneously. The morphology, composition, structure and thermal properties of as-synthesized Cu nanoparticles were investigated by means of transmission electron microscopy, X-ray powder diffraction, Fourier transform infrared spectrometry and differential thermal and thermogravimetric analysis. The tribological properties of as-synthesized Cu nanoparticles as an additive in liquid paraffin were evaluated with a four-ball friction and wear tester.

Findings
– It has been found that an as-synthesized Cu nanoparticle has a size of 2-5 nm and can be well dispersed in organic solvents. Tribological properties evaluation results show that as-synthesized Cu nanoparticles possess excellent anti-wear properties as an additive in liquid paraffin. The reason lies in that as-synthesized surface-capped Cu nanoparticles are able to deposit on sliding steel surface and form a low-shearing-strength protective layer thereon, showing promising application as an environmentally acceptable lubricating oil additive, owing to its free phosphorus and sulfur elements characteristics.

Originality/value
– Oil-soluble surface-modified Cu nanoparticles without phosphorus and sulfur were synthesized and its tribological properties as lubricating oil additives were also investigated in this paper. These results could be very helpful for application of Cu nanoparticles as environment-friendly lubricating oil additives.
Mindfulness-based wellbeing for socio-economically disadvantaged parents: a pre-post pilot study
Authors: Eames Catrin , Crane Rebecca , Gold Eluned , Pratt Sophie 
Published: April 2015

Purpose
– Behavioural parent training (PT) interventions partially mediate risk factors for the development of child behavioural problems. Mindfulness skills could have benefit in alleviating the impact of these risk factors for parents who are socio-economically disadvantaged. The paper aims to discuss these issues.

Design/methodology/approach
– A pre-post single group comparison of disadvantaged mothers attending the Mindfulness-Based Wellbeing for Parents (MBW-P) programme.

Findings
– Changes were observed in facets of parental stress (Parenting Stress Index-Short Form; Abidin, 1995), depression (Beck Depression Inventory-II; Beck et al., 1996) and brooding (Ruminative Responses Scale; Nolen-Hoeksema and Morrow, 1991), with moderate to large effect sizes and incidences of clinical change.

Research limitations/implications
– The research design, although pragmatic, includes a small sample and no control or long-term comparison group.

Social implications
– Mothers considered as the “hardest to reach” group in terms of vulnerability, risk factors and being likely to gain from intervention demonstrated positive shifts post-intervention. A targeted mindfulness-based intervention, delivered pragmatically within a health service context, may have benefit in reducing the impact of risk factors on parental wellbeing.

Originality/value
– To the authors’ knowledge, this is the first evaluation of a targeted mindfulness group delivered within routine health care settings, in identified “high risk” areas, by routine staff.
The impact of moral equity, relativism and attitude on individuals’ digital piracy behaviour in a developing country
Authors: Arli Denni , Tjiptono Fandy , Porto Rebecca 
Published: April 2015

Purpose
– The purpose of this paper is to explore the impact of moral equity, relativism, and attitude towards digital piracy behaviour in a developing country. End-user piracy is more difficult to detect than commercial piracy. Thus, an effective strategy to combat piracy needs a comprehensive understanding of both the supply and demand sides of piracy. The current study focuses on the demand side by investigating the impact of moral equity, relativism, and attitude on consumer piracy behaviour in Indonesia.

Design/methodology/approach
– Using a convenient sample in Yogyakarta, Indonesia, questionnaires were distributed in a large private university. In addition, through snowball sampling techniques, the surveys were also distributed to other adults who live within a walking distance from the campus. The data collection resulted in 222 usable surveys (a response rate of 68 per cent).

Findings
– In Indonesia, moral equity had a negative and significant impact on purchases of illegal copies of music CDs and pirated software. Relativism affects the purchase of pirated software positively, but its effect on purchases of illegal copies of CDs is insignificant. Attitude towards the act was negatively impacted by moral equity for CDs and software. Relativism only significantly affects the purchase of pirated software but in the opposite direction while it has failed to reach significance for illegal music CD purchases. Attitude towards the software piracy and purchases of illegal copies of music CDs positively affect consumer’s digital piracy behaviour. Finally, Indonesian consumers feel more morally wrong to purchase illegal copies of CDs than to buy pirated software.

Practical implications
– In the context of Indonesia, higher moral equity has affected piracy behaviour negatively. Therefore, efforts to reduce piracy should focus on highlighting the importance of fairness and justice. One of the main drivers of digital piracy (e.g. buying, downloading, copying, and sharing digital materials illegally) is overpriced products. It has led many Indonesians to believe that it is acceptable to purchase pirated software and illegal copies of CDs. Nonetheless, if companies are able to lower prices; thus make it affordable to consumers, consumers will perceive fairness and justice in purchasing original copies of software and CDs.

Originality/value
– There are very limited studies investigating factors impacting the purchase of pirated software and CDs in the developing countries specifically Indonesia, the fourth most populous nation in the world and one of the biggest markets for counterfeit products. This is one of first few studies exploring this issue in Indonesia.
Design and implementation of quality control loops
Authors: Schröder Malte , Schmitt Sebastian , Schmitt Robert 
Published: April 2015

Purpose
– Business processes have an open and dynamic character and are influenced by internal an external disturbances. Without an adequate use of feedback mechanisms, those processes become unstable and do not achieve the expected performance. The purpose of this paper is to face the challenge and to ensure a competitive quality level, a framework for entrepreneurial quality management is given.

Design/methodology/approach
– Using the method of analogy formation the transfer of cybernetic approaches to business processes is shown. Especially quality control loops are analysed in order to find appropriate solutions for their design and implementation in enterprises.

Findings
– As a core element of the paper an approach for the systematic implementation of control loops is given. This approach offers a framework and a description for an operative implementation of quality control loops for stable business processes.

Originality/value
– The idea to use closed quality control loops for the design of several processes is already known. Anyway, both a robust framework and a appropriate, sufficient and detailed description for an operative implementation is the new aspect and an important further development within the topic.
Integrating sustainability aspects into an integrated management system
Authors: Klute-Wenig Sandra , Refflinghaus Robert 
Published: April 2015

Purpose
– The purpose of this paper is the further development of an Excel-based integrated management system for the tool and cutlery industry regarding sustainability. The tool’s actual status allows integrating and implementing requirements considering work safety, environmental and quality management and a self-assessment for checking the level of requirements’ fulfilment. However, the topic of sustainability and requirements and risks going along with it are of great importance for the mostly small and medium companies of this industry. Therefore, the Excel-tool is being enhanced by integrating the requirements of risk, energy and sustainability management. The paper presents the advanced Excel-tool.

Design/methodology/approach
– The base for advancing the Excel-tool has been analysing the status quo of sustainability management in the companies. Moreover, a matrix for comparing the requirements has been enlarged regarding the standards for sustainability, risk and energy management and builds the base for further developing of the Excel-tool.

Findings
– This analysis has shown the need for action, regarding the topic of sustainability. Hence, the Excel-tool has been enlarged regarding the assessment of fulfilling the requirements of different management systems. It allows small- and medium-sized enterprises a detection of need for action to comply with the requirements of different management systems with minimal afford. By this, an easily evaluation and improvement of the companies’ management systems is enabled.

Originality/value
– The tool enables companies to easily evaluate the state of their integrated management system by themselves and assists when implementing additional management systems.
From IMS and six sigma toward TQM: an empirical study from Serbia
Authors: Majstorovic Vidosav , Sibalija Tatjana V. 
Published: April 2015

Purpose
– The purpose of this paper is to present the current status of a quality management practice in Serbia, in terms of the development and application of integrated managements systems (IMS), and research and implementation of Six Sigma and the related techniques.

Design/methodology/approach
– Two main aspects of total quality management (TQM) have been considered: institutional (organisational or strategic) aspect that corresponds to standardised management systems and their integration, and technical (quality engineering) aspect whose main contributor is Six Sigma. The findings of a comprehensive study on IMS implementation in Serbia have been presented, based on the results of a questionnaire that was sent to 54 organisations during 2013. Also, the significant technical improvements and tangible benefits of a recently conducted Six Sigma project were shown, including the application of the advanced quality engineering techniques within DMAIC method.

Findings
– Good QM practice in Serbia is improving, both in terms of the organisational (IMS) and technical (Six Sigma) aspect, that server as a good basis for the adoption of TQM in manufacturing companies from various sectors. It could be anticipated that these results will facilitate the adoption of an overall TQM culture in Serbia and leverage its future sustainability.

Originality/value
– This paper offers key insights into IMS and Six Sigma implementation in Serbia. This could encourage manufacturing organisations in developing countries to adopt IMS and Six Sigma, in order to boost the overall TQM culture and gain a competitive advantage.
Greenhouse Gas Mitigation through Sustainable Intensification of Livestock Production in the Brazilian Cerrado
Authors: de Oliveira Silva Rafael , Barioni Luis Gustavo , Moran Dominic 
Published: April 2015

SummaryBrazilian greenhouse gas emissions (GHG) are projected to reach 3.2 gigatonnes (CO2 eq.) by 2020. The government has made a voluntary commitment to reduce this figure by 40 per cent. A reduction in deforestation and livestock mitigation measures are key components of this commitment. Focusing on the Cerrado core (central Brazilian Savannah), we analyse abatement potential and cost‐effectiveness of GHG mitigation measures applicable to livestock production. We focus on the role of intensification measures, particularly pasture restoration and animal performance to meet the objectives of increasing beef production to meet higher demand, while simultaneously reducing emissions. We use a linear programming model that optimises pasture intensification levels according to biophysical and economic parameters and growth in beef demand. We estimate changes in soil carbon stocks generated by pasture management and land use change. According to a baseline projection, beef production in the Cerrado accounts for an average of approximately 122 million tonnes of CO2 eq. per year from 2010 to 2030. The results of our analysis suggest that by implementing cost‐effective measures, projected emissions in the region could be reduced by around 24 per cent. Pasture restoration, which will reduce deforestation, is the largest contributor to these results.

Published: April 2015

AbstractA well‐covered reference library is crucial for successful identification of species by DNA barcoding. The biggest difficulty in building such a reference library is the lack of materials of organisms. Herbarium collections are potentially an enormous resource of materials. In this study, we demonstrate that it is likely to build such reference libraries using the reconstructed (self‐primed PCR amplified) DNA from the herbarium specimens. We used 179 rosaceous specimens to test the effects of DNA reconstruction, 420 randomly sampled specimens to estimate the usable percentage and another 223 specimens of true cherries (Cerasus, Rosaceae) to test the coverage of usable specimens to the species. The barcode rbcLb (the central four‐sevenths of rbcL gene) and matK was each amplified in two halves and sequenced on Roche GS 454 FLX+. DNA from the herbarium specimens was typically shorter than 300 bp. DNA reconstruction enabled amplification fragments of 400–500 bp without bringing or inducing any sequence errors. About one‐third of specimens in the national herbarium of China (PE) were proven usable after DNA reconstruction. The specimens in PE cover all Chinese true cherry species and 91.5% of vascular species listed in Flora of China. It is very possible to build well‐covered reference libraries for DNA barcoding of vascular species in China. As exemplified in this study, DNA reconstruction and DNA‐labelled next‐generation sequencing can accelerate the construction of local reference libraries. By putting the local reference libraries together, a global library for DNA barcoding becomes closer to reality.

Published: April 2015

AbstractAlthough linkage maps are important tools in evolutionary biology, their availability for wild populations is limited. The population of song sparrows (Melospiza melodia) on Mandarte Island, Canada, is among the more intensively studied wild animal populations. Its long‐term pedigree data, together with extensive genetic sampling, have allowed the study of a range of questions in evolutionary biology and ecology. However, the availability of genetic markers has been limited. We here describe 191 new microsatellite loci, including 160 high‐quality polymorphic autosomal, 7 Z‐linked and 1 W‐linked markers. We used these markers to construct a linkage map for song sparrows with a total sex‐averaged map length of 1731cMand covering 35 linkage groups, and hence, these markers cover most of the 38–40 chromosomes. Female and male map lengths did not differ significantly. We then bioinformatically mapped these loci to the zebra finch (Taeniopygia guttata) genome and found that linkage groups were conserved between song sparrows and zebra finches. Compared to the zebra finch, marker order within small linkage groups was well conserved, whereas the larger linkage groups showed some intrachromosomal rearrangements. Finally, we show that as expected, recombination frequency between linked loci explained the majority of variation in gametic phase disequilibrium. Yet, there was substantial overlap in gametic phase disequilibrium between pairs of linked and unlinked loci. Given that the microsatellites described here lie on 35 of the 38–40 chromosomes, these markers will be useful for studies in this species, as well as for comparative genomics studies with other species.
Review of rope‐based access methods for the forest canopy: safe and unsafe practices in published information sources and a summary of current methods
Authors: Anderson David L. , Koomjian Will , French Brian , Altenhoff Scott R. , Luce James 
Published: April 2015

SummaryThe availability of reliable information on tree climbing methods is critical for the development of canopy science and for the safety of workers accessing the forest canopy.To assess the breadth and quality of information contained in published climbing information, we performed searches in Web of Science and Google Scholar and evaluated 54 published sources on 10 predetermined criteria related to safety.We found a high incidence of unsafe recommendations that, if followed, could result in serious injury or death. Common errors included recommendations for equipment not suitable for tree climbing, advocating methods suitable for rock climbing but that can result in falls and trauma in tree climbing, and outdated information that no longer reflects best practices.We conclude by providing safety recommendations and a short review of tree climbing methods. This article thus serves as a guide for finding and interpreting best sources of methods for canopy access.

ObjectiveTo perform a meta‐analysis on studies reporting prevalence of Toxoplasma gondii (T. gondii) infection in any psychiatric disorder compared with healthy controls. Our secondary objective was to analyze factors possibly moderating heterogeneity.MethodA systematic search was performed to identify studies into T. gondii infection for all major psychiatric disorders versus healthy controls. Methodological quality, publication bias, and possible moderators were assessed.ResultsA total of 2866 citations were retrieved and 50 studies finally included. Significant odds ratios (ORs) with IgG antibodies were found in schizophrenia (OR 1.81, P < 0.00001), bipolar disorder (OR 1.52, P = 0.02), obsessive–compulsive disorder (OR 3.4, P < 0.001), and addiction (OR 1.91, P < 0.00001), but not for major depression (OR 1.21, P = 0.28). Exploration of the association between T. gondii and schizophrenia yielded a significant effect of seropositivity before onset and serointensity, but not IgM antibodies or gender. The amplitude of the OR was influenced by region and general seroprevalence. Moderators together accounted for 56% of the observed variance in study effects. After controlling for publication bias, the adjusted OR (1.43) in schizophrenia remained significant.ConclusionThese findings suggest that T. gondii infection is associated with several psychiatric disorders and that in schizophrenia reactivation of latent T. gondii infection may occur.

AbstractBackgroundCow's milk allergy (CMA) is one of the most commonly reported childhood food problems. Community‐based incidence and prevalence estimates vary widely, due to possible misinterpretations of presumed reactions to milk and differences in study design, particularly diagnostic criteria.MethodsChildren from the EuroPrevall birth cohort in 9 European countries with symptoms possibly related to CMA were invited for clinical evaluation including cows' milk‐specific IgE antibodies (IgE), skin prick test (SPT) reactivity and double‐blind, placebo‐controlled food challenge.ResultsAcross Europe, 12 049 children were enrolled, and 9336 (77.5%) were followed up to 2 years of age. CMA was suspected in 358 children and confirmed in 55 resulting in an overall incidence of challenge‐proven CMA of 0.54% (95% CI 0.41–0.70). National incidences ranged from 1% (in the Netherlands and UK) to <0.3% (in Lithuania, Germany and Greece). Of all children with CMA, 23.6% had no cow's milk‐specific IgE in serum, especially those from UK, the Netherlands, Poland and Italy. Of children with CMA who were re‐evaluated one year after diagnosis, 69% (22/32) tolerated cow's milk, including all children with non‐IgE‐associated CMA and 57% of those children with IgE‐associated CMA.ConclusionsThis unique pan‐European birth cohort study using the gold standard diagnostic procedure for food allergies confirmed challenge‐proven CMA in <1% of children up to age 2. Affected infants without detectable specific antibodies to cow's milk were very likely to tolerate cow's milk one year after diagnosis, whereas only half of those with specific antibodies in serum ‘outgrew’ their disease so soon.
