Authors: Pan Yu , Zhang Ji , Zhao Yan‐Li , Wang Yuan‐Zhong , Jin Hang 
Published: February 2016

AbstractIntroductionGentianaceae species which widely occur all over the world are used as folk medicine and raw food material with bitter properties. Although comparative analysis on metabolites in several Gentianaceae species has been reported, metabolic similarities used for chemotaxonomic studies are not yet clear.ObjectiveTo systematically characterise the variations of holistic metabolome and characteristic metabolites (iridoid glycosides and phenols) in nine Gentianaceae species from western China.MethodologyFourier transform infrared (FT‐IR) spectroscopy was applied to determine the variations of holistic metabolome. A targeted metabolic profiling using liquid chromatography with tandem mass spectrometry (LC–MS/MS) was established for determination of seven characteristic metabolites and identification of their derivatives. Both FT‐IR and LC–MS/MS data were subjected to chemometrics analysis for exploring variations in iridoid glycosides and phenols within these species.ResultsHolistic metabolome in genera Gentiana and Swertia was largely different. Diversity of the biosynthetic pathway of iridoid glycosides was also observed in these species. Principal component analysis (PCA) showed a clear separation according to infrageneric classifications of genus Gentiana. Some secondary metabolites, such as mangiferin, rhodenthoside A‐C, isoorientin, isovitexin, amarogentin, and swertianolin would serve as potential chemotaxonomic markers to differentiate Gentianaceae species. Furthermore, the accumulation of the six major metabolites seems to depend on geographical regions in Sect. Monopodiae and Sect. Cruciata.ConclusionsThe combination of LC–MS/MS and FT‐IR would provide some potential evidence on chemotaxonomic studies of Gentianaceae. Copyright © 2016 John Wiley & Sons, Ltd.
Ageing of Australian DNAN Based Melt‐Cast Insensitive Explosives
Authors: Provatas Arthur , Wall Craig 
Published: February 2016

Abstract2,4‐Dinitroanisole (DNAN) is a new melt‐cast matrix ingredient that replaces traditional TNT in TNT‐based melt‐cast explosives. Aside from sensitiveness improvements, the use of DNAN allows for the continued operation of existing melt‐cast facilities (for example the Australian Munitions plants located at Mulwala and Benalla) without the need for major plant modifications. Researchers at Defence Science and Technology Group (DST Group) have developed several DNAN based formulations that have been extensively characterized. In an effort to better understand the ageing properties of these formulations, an accelerated ageing program was undertaken. Testing was conducted under two different ageing conditions; the first test condition was conducted at a constant 60 °C with ambient humidity and the second test condition was the A2 diurnal cycle (representative of hot dry climates). Analysis of the formulation density, sensitiveness, mechanical and thermal properties was made at three‐month intervals for a period of 12 months and results compared with conventional explosives similarly aged. For all DNAN‐based formulations there was negligible change in impact, friction, electrostatic discharge, and thermal testing over time. These results highlight the ability of the ARX formulations to diurnal temperature cycling and to hold favorable sensitiveness properties to various stimuli.
Introducing folding stability into the score function for computational design of RNA‐binding peptides boosts the probability of success
Authors: Xiao Xingqing , Agris Paul F. , Hall Carol K. 
Published: February 2016

ABSTRACTA computational strategy that integrates our peptide search algorithm with atomistic molecular dynamics simulation was used to design rational peptide drugs that recognize and bind to the anticodon stem and loop domain (ASLLys3) of human
for the purpose of interrupting HIV replication. The score function of the search algorithm was improved by adding a peptide stability term weighted by an adjustable factor λ to the peptide binding free energy. The five best peptide sequences associated with five different values of λ were determined using the search algorithm and then input in atomistic simulations to examine the stability of the peptides' folded conformations and their ability to bind to ASLLys3. Simulation results demonstrated that setting an intermediate value of λ achieves a good balance between optimizing the peptide's binding ability and stabilizing its folded conformation during the sequence evolution process, and hence leads to optimal binding to the target ASLLys3. Thus, addition of a peptide stability term significantly improves the success rate for our peptide design search. Proteins 2016; 84:700–711. © 2016 Wiley Periodicals, Inc.

Published: February 2016

AbstractThis article presents the results on a fabrication of silicon nanowires by a two‐step metal‐assisted chemical etching. Morphological and optical properties of the obtained silicon nanostructures depending on the type and resistivity of the initial silicon wafer have been studied. In addition, we have used the silicon nanowires as templates for zinc oxide and silver deposition. The resulting nanocomposites have been shown to demonstrate intensive photoluminescence and activity in the surface enhanced Raman scattering respectively. (© 2016 WILEY‐VCH Verlag GmbH & Co.

Luminescence dynamics of hybrid ZnO nanowire/CdSe quantum dot structures
Authors: Bley Stephanie , Albrecht Friederike , Resch Sebastian , Waldvogel Siegfried R. , Menzel Andreas , Zacharias Margit , Voss Tobias , Gutowski Jürgen 
Published: February 2016

AbstractColloidal CdSe quantum dots (QDs) functionalized with different organic linker molecules are attached to ZnO nanowires (NWs) to investigate the electron transfer dynamics between dots and wires. After linking the quantum dots to the nanowires, the photo‐induced electron transfer (PET) from the QDs into the NWs becomes visible in the PL transients by a decrease of dot luminescence decay time. The different recombination paths inside the QDs and the PET process are discussed in the framework of a rate equation model. Photoconductivity studies confirm the electron transfer by demonstrating a strong enhancement of the wire photocurrent under light irradiation into the dot transition.

Elucidating the Indirect Contributions of Packaging to Sustainable Development: A Terminology of Packaging Functions and Features
Authors: Lindh Helena , Williams Helen , Olsson Annika , Wikström Fredrik 
Published: February 2016

Packaging has great potential to contribute to sustainable development through its functions. Previous research has indicated a need for increased knowledge among consumers, suppliers, authorities and media of how packaging functions and features influence sustainable development. Previous research also shows the need for a common terminology of packaging functions and features in order to facilitate and improve communication and understanding in development and decision processes.This conceptual paper sets out to identify, collect, analyse and systemize packaging functions and features and evaluate them based on their indirect contributions to sustainable development. The systemized functions and features are expressed in generic terminology. Three clusters of packaging functions were identified from the literature: protect, facilitate handling and communicate. Nineteen packaging features were also identified. They were grouped under the three functions and elaborated based on their indirect contributions to the environmental, social and economic dimensions of sustainable development. Fourteen potential positive indirect effects were identified including decreased product waste, reduced risk for human health hazards, increased handling and transport efficiency. Decreased product waste was generated by 13 of the features and was thus the most frequently appearing. Reducing waste is thereby indicated to be a manifold matter, but also one of great potential.The proposed terminology can contribute to an increased understanding of how packaging can actually contribute to sustainable development. In a theoretical context, this paper attempts to complement earlier work in sustainable packaging development by its emphasis on the indirect contributions of packaging to sustainable development.
Psychometric Properties of the Work Well Index: A Short Questionnaire for Work‐Related Stress
Authors: Mauss Daniel , Li Jian , Angerer Peter 
Published: February 2016

AbstractThe aim of this study was to test the psychometric properties of a short questionnaire for work‐related stress entitled Work Well index (WWi) and its interaction with different variables of self‐reported health. An online survey was conducted in a sample of 1,218 employees (51% female) in four countries of an international insurance company. Internal consistency reliability, factorial validity, convergent validity and criterion validity of the 10‐item WWi were analyzed. Good internal consistency reliability of the WWi was obtained (Cronbach's α coefficient = 0.85). Confirmatory factor analysis showed a satisfactory model fit of the data (AGFI = 0.92). The WWi was highly correlated to conceptually close constructs such as demand–control, effort–reward imbalance and workplace social capital (p < 0.001). Moreover, the 10‐item WWi was significantly (p < 0.001) associated with elevated risk of self‐rated health, absenteeism, presenteeism and depression (odds ratio 1.63, 1.36, 2.08, 2.95, respectively). We conclude that this short questionnaire is a reliable and valid instrument measuring psychosocial stress at work. Copyright © 2016 John Wiley & Sons, Ltd.
How Effective are Mindfulness‐Based Interventions for Reducing Stress Among Healthcare Professionals? A Systematic Review and Meta‐Analysis
Authors: Burton Amy , Burgess Catherine , Dean Sarah , Koutsopoulou Gina Z. , Hugh‐Jones Siobhan 
Published: February 2016

AbstractWorkplace stress is high among healthcare professionals (HCPs) and is associated with reduced psychological health, quality of care and patient satisfaction. This systematic review and meta‐analysis reviews evidence on the effectiveness of mindfulness‐based interventions (MBIs) for reducing stress in HCPs. A systematic literature search was conducted. Papers were screened for suitability using inclusion criteria and nine papers were subjected to review and quality assessment. Seven papers, for which full statistical findings could be obtained, were also subjected to meta‐analysis. Results of the meta‐analysis suggest that MBIs have the potential to significantly improve stress among HCPs; however, there was evidence of a file drawer problem. The quality of the studies was high in relation to the clarity of aims, data collection and analysis, but weaker in terms of sample size and the use of theoretical frameworks. MBIs have the potential to reduce stress among HCPs; however, more high‐quality research is needed before this finding can be confirmed. Future studies would benefit from long‐term follow‐up measures to determine any continuing effects of mindfulness training on stress outcomes. Copyright © 2016 John Wiley & Sons, Ltd.
Foreign Direct Investment and Economic Growth in SSA: The Role of Institutions

Published: February 2016

AbstractThis article examines the relationship among foreign direct investment (FDI), institutions and economic growth in sub‐Saharan Africa in different country environs. We employ a two‐step generalized methods of moments estimator with Weidmeijer corrected standard errors and orthogonal deviations to examine the empirical relations. In the full sample, we do not find evidence that FDI promotes growth. We also do not find a significant relationship between institutions and economic growth. Finally, we do not find convincing evidence that institutions alter favorably the effect of FDI on economic growth. In the subsample that excludes countries with developed financial markets, again we do not find a significant relation between FDI and economic growth. However, we find evidence suggesting that institutions play a direct role in spurring economic growth. Further, the quality of institutions seems to alter favorably the relationship between FDI and economic growth. Finally, in the sample that excludes countries with abundant natural resources, we find a direct and positive relationship between FDI and economic growth. We also find a direct relationship between institutions and economic growth. The growth‐enhancing effects of FDI, however, seem to reduce as the quality of institutions improves. The major implication from our study is that countries should take into consideration their own realities when they fashion policies to benefit from FDI in terms of achieving better growth outcomes. © 2016 Wiley Periodicals, Inc.
How to assess a company’s open innovation situation?
Authors: Guertler Matthias R. , Michailidou Ioanna , Lindemann Udo 
Published: February 2016

Open Innovation (OI) supports companies in systematically collaborating with external partners, offering various advantages. However, companies still face several challenges when applying OI, e.g., identifying relevant OI partners, collaboration methods, and project risks. Often, insufficient planning is the reason for subsequent deficits in OI projects. The analysis of relevant context factors (‘situation’) is important, which affect and constrain OI. To date, a general approach for analyzing (open) innovation situations or guidelines for developing one do not exist. Usually researchers develop their own situation analysis, including extensive literature reviews and experiencing similar challenges. This publication sets the basis for successfully planning OI projects. It focuses on developing an analysis approach for OI situations and supports other researchers in developing their own analysis approaches. The resultant objectives of the publication are to: (1) provide a list of potential situation analysis criteria; (2) provide a guideline for developing a situation analysis; (3) provide initial indications of relevant OI-specific situation criteria. The criteria were derived from the literature and qualitatively evaluated by three industry partners to assess their usability. Although this work is exploratory, and the results are not automatically generalizable, it is an important contribution for ensuring the success of OI, and for analyzing enablers and barriers to knowledge transfer from academia to industry.
Ethnic elders and pension protection in the United Kingdom
Authors: VLACHANTONI ATHINA , FENG ZHIXIN , EVANDROU MARIA , FALKINGHAM JANE 
Published: February 2016

ABSTRACTPension receipt in later life is determined by the way in which individuals' pension contributions and circumstances over the lifecourse interact with eligibility rules. Within the British context, such pensions relate to sources such as the State Pension, an occupational or private pension, and Pension Credit. Existing research shows that membership of certain ethnic groups is associated with a lower likelihood of receiving occupational or private pensions. Data from Understanding Society allows us to build on existing evidence by examining the factors associated with the receipt of three different kinds of pension income – State, occupational/private and Pension Credit – among older men and women from separate Black and Minority Ethnic (BME) groups. The results show that belonging to certain BME groups reduces one's chances of receiving the State Pension or an occupational/private pension, but increases the chance of receiving Pension Credit. The gender-specific analysis shows that these results hold true for many BME groups of men, whereas among women, only Pakistani women are less likely than White British women to receive an occupational/private pension. Such findings provide up-to-date empirical evidence that ethnic inequalities in pension protection are still evident and contribute to the increasingly important debate in the United Kingdom and elsewhere regarding migrants' social security and welfare over the lifecourse and in later life.
Age and learning environment: Are children implicit second language learners?
Authors: LICHTMAN KAREN 
Published: February 2016

AbstractChildren are thought to learn second languages (L2s) using primarily implicit mechanisms, in contrast to adults, who primarily rely on explicit language learning. This difference is usually attributed to cognitive maturation, but adults also receive more explicit instruction than children, which may influence their learning strategies. This study crosses instruction condition with age, teaching forty children aged 5;3 to 7;11 and forty adults an artificial mini-language under implicit or explicit training conditions. Participants produced novel sentences and judged sentence grammaticality equally well in either condition, but both children and adults in the explicit training condition developed greater awareness of the mini-language's structures – and greater awareness was associated with better performance for both age groups. Results show that explicit instruction affects children and adults in the same way, supporting the hypothesis that age differences in implicit vs. explicit L2 learning are not exclusively caused by maturation, but also influenced by instruction.
Early child L2 acquisition: Age or input effects? Neither, or both?
Authors: UNSWORTH SHARON 
Published: February 2016

AbstractThis paper explores whether there is evidence for age and/or input effects in child L2 acquisition across three different linguistic domains, namely morphosyntax, vocabulary, and syntax–semantics. More specifically, it compares data from English-speaking children whose age of onset to L2 Dutch was between one and three years with data from children whose age of onset was between four and seven years in their acquisition of verb morphology, verb placement, vocabulary, and direct object scrambling. The main findings were that there were no significant differences between the two groups in any of these areas and, with the exception of scrambling, current amount of exposure was the only factor significantly related to children's scores. The paper discusses the theoretical significance of these findings with respect to the role of input in the language acquisition process and the claim that there is a critical period ending within (early) childhood.
Strategic style change using grammar transformations
Authors: Khan Sumbul , Chase Scott C. 
Published: February 2016

AbstractNew styles can be created by modifying existing ones. In order to formalize style change using grammars, style has to be formally defined in the design language of a grammar. Previous studies in the use of grammars for style change do not give explicit rationale for transformation. How would designers decide which rules to modify in a grammar to generate necessary changes in style(s) of designs? This paper addresses the aforementioned issues by presenting a framework for strategic style change using goal-driven grammar transformations. The framework employs a style description scheme constructed by describing the aesthetic qualities of grammar elements using adjectival descriptors. We present techniques for the formal definition of style in the designs generated by grammars. The utility of the grammar transformation framework and the style description scheme is tested with an example of mobile phone design. Analyses reveal that constraining rules in grammars is a valid technique for generating designs with a dominance of desired adjectival descriptors, thus aiding in strategic style change.

AbstractSummer iron (Fe) fertilization in the Ross Sea has previously been observed in association with diatom productivity, lithogenic particles and excess Fe in the water column. This productivity event occurred during an early breakout of sea ice via katabatic winds, suggesting that aeolian dust could be an important source of lithogenic Fe required for diatom growth in the Ross Sea. Here we investigate the provenance of size-selected dust deposited on sea ice in McMurdo Sound, south-western (SW) Ross Sea. The isotopic signature of McMurdo Sound dust (0.70533<87Sr/86Sr<0.70915 and -1.1<εNd(0)<3.45) confirms that dust is locally sourced from the McMurdo Sound debris bands and comprises a two-component mixture of McMurdo Volcanic Group and southern Victoria Land lithologies. In addition, the provenance of lithogenic sediment trapped in the water column was investigated, and the isotopic signature (εNd(0)=3.9, 87Sr/86Sr=0.70434) is differentiated from long-range transported dust originating from South America and Australia. Elevated lithogenic accumulation rates in deeper sediment traps in the Ross Sea suggest that sinking particles in the water column cannot simply result from dust input at the surface. This discrepancy can be best explained by significant upwelling and remobilization of lithogenic Fe from the sea floor.
Where the Two Worlds Met: Spreading a Buddhist Canon in Wanli (1573–1620) China
Authors: ZHANG DEWEI 
Published: February 2016

AbstractThe imperial bestowal, as a major way of distributing the Buddhist canon, profoundly affected the contours of Buddhism in late imperial China. But why did the inner court engage in the distribution? How did it choose the recipient from the outside world? How was it possible for an aspirant to the canon to win out among the competitors? These questions concern the dynamics and mechanism behind the diffusion of the canon. They also cast new light on the relationship between Buddhism and the state and local society by revealing how the two otherwise separated worlds interacted. This paper is intended to tackle these unexplored questions by examining the extensive bestowal of the Ming Beizang during the Wanli court (1573–1620). It first makes a survey, revealing how uneven the distribution was in terms of both time and region. It then explores the motives of the imperial members as patrons in the context of court politics. Its focus, however, is on the agents and elements working behind the selection of the beneficiaries, and how their interplays conditioned the influence of the canon in local societies. In the process, the roles of the emperor, court women, eunuchs, officials, monks, and local elites are all examined.
