The mechanism of charge density wave in Pt-based layered superconductors: SrPt2As2 and LaPt2Si2
Authors: Kim Sooran , Kim Kyoo , Min B. I. 
Published: October 2015

AbstractThe intriguing coexistence of the charge density wave (CDW) and superconductivity in SrPt2As2 and LaPt2Si2 has been investigated based on the ab initio density functional theory band structure and phonon calculations. We have found that the CDW instabilities for both cases arise from the q-dependent electron-phonon coupling with quasi-nesting feature of the Fermi surface. The band structure obtained by the band-unfolding technique reveals the sizable q-dependent electron-phonon coupling responsible for the CDW instability. The local split distortions of Pt atoms in the [As-Pt-As] layers play an essential role in driving the five-fold supercell CDW instability as well as the phonon softening instability in SrPt2As2. By contrast, the CDW and phonon softening instabilities in LaPt2Si2 occur without split distortions of Pt atoms. The phonon calculations suggest that the CDW and the superconductivity coexist in [X-Pt-X] layers (X = As or Si) for both cases.

AbstractThis paper describes the generation of “click-crosslinkable“ and “photodegaradable“ gelatin hydrogels from the reaction between dibenzocycloctyl-terminated photoclevable tetra-arm polyethylene glycol and azide-modified gelatin. The hydrogels were formed in 30 min through the click-crosslinking reaction. The micropatterned features in the hydrogels were created by micropatterned light irradiation; the minimum resolution of micropatterning was 10-μm widths for line patterns and 20-μm diameters for circle patterns. Cells were successfully encapsulated in the hydrogels without any loss of viability across a wide concentration range of crosslinker. In contrast, an activated-ester-type photocleavable crosslinker, which we previously used to prepare photodegradable gelatin hydrogels, induced a decrease in cell viability at crosslinker concentrations greater than 1.8 mM. We also observed morphology alteration and better growth of cancer cells in the click-crosslinked photodegradable gelatin hydrogels that included matrigel than in the absence of matrigel. We also demonstrated micropatterning of the hydrogels encapsulating cells and optical cell separation. Both of the cells that remained in the non-irradiated area and the cells collected from the irradiated area maintained their viability.
The TRIB3 Q84R polymorphism, insulin resistance and related metabolic alterations
Authors: Prudente Sabrina , Trischitta Vincenzo 
Published: October 2015

Insulin resistance is pathogenic for many prevalent disorders including type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), polycystic ovary syndrome, non-alcoholic fatty liver disease, Alzheimer's and Parkinson's diseases and several cancers. Unravelling molecular abnormalities of insulin resistance may therefore pave the way for tackling such heavy weight on healthcare systems. This review will be focused on studies addressing the role of genetic variability of TRIB3, an inhibitor of insulin signalling at the AKT level on insulin resistance and several related abnormalities. Studies carried out in several cultured cells clearly report that the TRIB3 Q84R missense polymorphism, is a gain-of-function amino acid substitution, with the Arg84 variant being a stronger inhibitor of insulin-mediated AKT activation as compared with the more frequent Gln84 variant. Given the key role of AKT in modulating not only insulin signalling but also insulin secretion, it was not surprising that β-cells and human pancreatic islets carrying the Arg84 variant showed also impaired insulin secretion. Also, of note is that in human vein endothelial cells carrying the Arg84 variant showed a reduced insulin-induced nitric oxide release, an established early atherosclerotic step. Accordingly with in vitro studies, in vivo studies indicate that TRIB3 Arg84 is associated with insulin resistance, T2DM and several aspects of atherosclerosis, including overt CVD. In all, several data indicate that the TRIB3 Arg84 variant plays a role on several aspects of glucose homoeostasis and atherosclerotic processes, thus unravelling new molecular pathogenic mechanisms of highly prevalent disorders such as T2DM and CVD.
Peroxisomal ABC transporters: functions and mechanism

Published: October 2015

Peroxisomes are arguably the most biochemically versatile of all eukaryotic organelles. Their metabolic functions vary between different organisms, between different tissue types of the same organism and even between different developmental stages or in response to changed environmental conditions. New functions for peroxisomes are still being discovered and their importance is underscored by the severe phenotypes that can arise as a result of peroxisome dysfunction. The β-oxidation pathway is central to peroxisomal metabolism, but the substrates processed are very diverse, reflecting the diversity of peroxisomes across species. Substrates for β-oxidation enter peroxisomes via ATP-binding cassette (ABC) transporters of subfamily D; (ABCD) and are activated by specific acyl CoA synthetases for further metabolism. Humans have three peroxisomal ABCD family members, which are half transporters that homodimerize and have distinct but partially overlapping substrate specificity; Saccharomyces cerevisiae has two half transporters that heterodimerize and plants have a single peroxisomal ABC transporter that is a fused heterodimer and which appears to be the single entry point into peroxisomes for a very wide variety of β-oxidation substrates. Our studies suggest that the Arabidopsis peroxisomal ABC transporter AtABCD1 accepts acyl CoA substrates, cleaves them before or during transport followed by reactivation by peroxisomal synthetases. We propose that this is a general mechanism to provide specificity to this class of transporters and by which amphipathic compounds are moved across peroxisome membranes.
Communicating with smallholder farming families - a review with a focus on agro-dealers and youth as intermediaries in sub-Saharan Africa.
Authors: Sones K. R. , Oduor G. I. , Watiti J. W. , Romney D. 
Published: October 2015

Abstract
The CABI African Soil Health Consortium (ASHC) aims to improve the livelihoods of smallholder farmers through better access to practical information about integrated soil fertility management. The next phase focuses on two types of intermediaries to reach smallholder farmers: agro-dealers and youth. This review reflects this focus and is therefore biased towards recent publications relevant to these intermediaries and also the impact of gender on provision of and access to agricultural information. There is a consistent demand for information on new varieties, pests and diseases, use of pesticides and fertilizer, as well as weather, credit and markets. The most frequently used sources of information are still the more traditional ones. Extension services, family, friends and neighbours, and agro-dealers are all important face-to-face sources of information. Radio dominates as the main mass media source. Local agro-dealers are often included by smallholder farmers among the most frequently used sources of information and they enjoy a degree of trust. There has been considerable investment by donors in extending and strengthening agro-dealer networks over recent years, including more emphasis on their roles as sources of information and advice. A new type of tech-savvy young entrepreneurial farmer is emerging who is more likely to wield a smartphone than a hoe. This is especially important against a background in which, despite the median age in African being just 19.7 years, the average age of farmers is estimated to be over 55. Family farming is receiving renewed emphasis. During its phase 2, which will run from 2015 to 2019, ASHC will share its experiences, successes and failures, and lessons learned in working with agro-dealers and youth intermediaries. In this way it aims to help others to communicate their key messages more effectively including via these intermediaries.
Kairos, Free Speech, and the Material Conditions of State Power in the United States: The Case of World War I
Authors: Trasciatti Mary Anne 
Published: October 2015

ABSTRACTThis article considers versions of kairos within the context of World War I and the 1917 Espionage Act, a U.S. law that significantly narrowed parameters for free speech to protect the national interest. Many political activists and pacifists who perceived the war as an opportune moment for a critique of state power and corporate interests suffered material consequences for making such a critique—or remained silent for fear of consequences. While affirming the materiality of kairos and the centrality of body performance, I suggest an expanded version embodying the principle that freedom to respond to kairotic moments is always a product of struggle.
Places of Protest in Putin’s Russia: Pussy Riot’s Punk Prayer and Show Trial
Authors: Haskins Ekaterina V. 
Published: October 2015

ABSTRACT
In spring 2012 the Russian feminist art collective Pussy Riot became world famous when five of its members were arrested for their “Punk Prayer for Freedom” in the Cathedral of Christ the Savior in central Moscow. Western media swiftly embraced the group and celebrated it as an icon of youthful female rebellion against Putin’s authoritarian regime. Yet the Western reception largely obscured the “regional accent” of the group’s protest rhetoric. This article seeks to restore this regional accent by foregrounding the rhetorical significance of place in Pussy Riot’s acts of protest.

Published: October 2015

Abstract
Tensile strained single-crystal GeSn on insulator (GSOI) was obtained using self-organized seeding lateral growth. Segregation of Sn atoms and Sn distribution occurred during the lateral growth of the GeSn stripe. At both edges of the GSOI, Sn concentration distribution was found in good agreement with calculation based on the Scheil equation. P-channel metal–oxide–semiconductor field effect transistors were fabricated using the GSOI materials. Good transistor performance with the low field peak hole mobility of 383 cm2 V−1 s−1 was obtained, which indicated the high quality of this GSOI structure.

Abstract
Summary: The development of the Infinium HumanMethylation450 BeadChip enables epigenome-wide association studies at a reduced cost. One observation of the 450K data is that many CpG sites the beadchip interrogates have very large measurement errors. Including these noisy CpGs will decrease the statistical power of detecting relevant associations due to multiple testing correction. We propose to use intra-class correlation coefficient (ICC), which characterizes the relative contribution of the biological variability to the total variability, to filter CpGs when technical replicates are available. We estimate the ICC based on a linear mixed effects model by pooling all the samples instead of using the technical replicates only. An ultra-fast algorithm has been developed to address the computational complexity and CpG filtering can be completed in minutes on a desktop computer for a 450K data set of over 1000 samples. Our method is very flexible and can accommodate any replicate design. Simulations and a real data application demonstrate that our whole-sample ICC method performs better than replicate-sample ICC or variance-based method.
Availability and implementation: CpGFilter is implemented in R and publicly available under CRAN via the R package ‘CpGFilter’.

Considerations for Multiteam Systems in Emergency Medical Services
Authors: Lazzara Elizabeth H. , Keebler Joseph R. , Shuffler Marissa L. , Patzer Brady , Smith Dustin C. , Misasi Paul 
Published: October 2015

Objective
Despite good intentions, mishaps in teamwork continue to affect patient's lives and plague the medical community at large and Emergency Medical Services (EMS) in particular. Effective and efficient management of patient care necessitates that sets of multiple teams (i.e., multiteam systems [MTSs] - EMS ground crews, EMS air crews, dispatch, and receiving hospital teams) seamlessly work together. Although advances have been made to improve teams, little research has been dedicated to enhancing MTSs especially in the critical yet often under studied domain of EMS. The purpose of this paper is to assist the pre-hospital community in strengthening patient care by presenting considerations unique to multiteam systems.

Methods
We synthesized the literature pertinent to multi-team systems and emergency medical services.

Results
From this synthesis, we derived five unique considerations: goals, boundary spanning, adaptation, leadership, and social identity.

Conclusions
MTSs are prevalent in prehospital care, as they define how multiple component healthcare teams work together to intervene in emergency situations. We provided some initial directions regarding considerations for success in EMS MTSs based on existing research, but we also recognize the need for further study on these issues.
UK substance use policy research should think local
Authors: Haydock William 
Published: October 2015

Purpose
– The purpose of this paper is to consider how policy researchers should respond to recent developments in substance use and the governance of drug and alcohol policy in the UK.

Design/methodology/approach
– The paper takes two elements from the 2010 UK Drug Strategy – supply and treatment – and considers a case study in each to briefly examine the potential role of local policymakers in shaping how substance use is experienced.

Findings
– It is argued that the Coalition Government’s health reforms have given local commissioners greater autonomy over treatment policy than they had under the preceding Labour Government. Similarly, the regulation of new psychoactive substances in the UK has left local areas to determine their own approach to controlling supply through retail outlets.

Research limitations/implications
– Drawing on the broader academic literature on policymaking, this paper calls for ethnographic research into local policymaking related to substance use, which will help to illuminate how perceived policy problems are shaped by particular local systems and understandings of evidence.

Originality/value
– While this paper is not unique in identifying the importance of locally based research, it identifies the particular relevance of this research agenda in the UK today. It seeks to inform and encourage research that can shape the development of local policymaking.
From civil disobedience to drug users’ well-being: grass-roots activity and the establishment of drug consumption rooms in Denmark
Authors: Ankjærgaard Simon Kratholm , Christensen Ivan , Ege Peter Preben , Gotfredsen Nanna W. , Kjær Jørgen , Olsen Michael Lodberg , Majlund Kaj Lykke 
Published: October 2015

Purpose
– The purpose of this paper is to provide contextual information around the grass-roots activities which resulted in legislation allowing the opening of drug consumption rooms in Denmark. This background has not been included in, e.g. the annual Danish Focal Point reports to the EMCDDA.

Design/methodology/approach
– An account by some of those involved on the grass-roots and political activities which resulted in the enabling changes in law and the provision of building-based drug consumption rooms in Denmark.

Findings
– The actions described originated in a concern for the health and well-being of drug users. That grass-roots action can act as a catalyst for political changes in social policy to take account of the situations and needs of socially marginalised groups.

Research limitations/implications
– The paper describes the sequence of grass-roots actions from the point of view of those involved. It does not seek to represent the views of those opposed to the activists’ aims.

Practical implications
– The use of international evidence to support policy and legal changes in one nation, Denmark, in order to improve conditions for drug users. The need for funding commitments to support and realise the legal and policy changes.

Social implications
– The success of long-term campaigning on behalf of a specific marginalised and socially excluded group of citizens and the countering of myths and stigma associated with this group.

Originality/value
– This is a unique account told by those directly involved of the social and campaigning processes which led to a change in the law and a shifting of popular and political opinion and action.
Back to nature
Authors: Gration David , Raciti Maria , Walters Gabby 
Published: October 2015

Purpose
– The purpose of this paper is to explore festivalgoer/camper perceptions of and responses to the non-urban festival service environment (blended festivalscape).

Design/methodology/approach
– For this exploratory study a quantitative approach was adopted. A self-administered online survey was administered to recipient members of an Australian non-urban festival e-newsletter database resulting in 398 usable responses from festival campers.

Findings
– Environmental beliefs held by festival campers’ influenced their perceptions of naturescape, socialscape and overall satisfaction. Festival campers’ who attended more than once were found to have stronger pro-environmental beliefs than those who attended once. Festival camper perception of naturescape has a positive moderating influence leading to greater overall satisfaction and the likelihood of repeat attendance and positive word-of-mouth.

Research limitations/implications
– It is very important to know how festivalgoers perceive and relate to their festival service environment. Critical to the appeal and success of the non-urban festival is the alignment of festivalgoer environmental beliefs to the natural setting in which they are held. Limitations include use of a single case study context.

Originality/value
– This paper responds to lack of research on non-urban festivals when compared to urban festivals and the surprisingly little interest shown in the central role of natural settings and the camping experience. A closer understanding of the environmental beliefs of campers at non-urban festivals has the potential to provide beneficial outcomes for people, profit and planet.
Purposeful pedaling: analyzing MS 150 participant behavior
Authors: Gregg Elizabeth A. , Pierce David A. , Sweeney Kristi M. , Lee Jason W. 
Published: October 2015

Purpose
– The purpose of this paper is to explore factors affecting participant awareness, attraction, and attachment to the National Multiple Sclerosis Society’s (NMSS) MS 150 PGA Tour Cycle to the Shore charitable bike ride utilizing the Psychological Continuum Model (PCM) developed by Funk and James. In addition, the authors sought to outline variables sport organizations can use to predict donor behavior.

Design/methodology/approach
– Data for this project were derived from an electronic survey distributed to race participants and was analyzed in SPSS® software. Regression analysis was employed.

Findings
– The findings support previous research employing the PCM; wherein social situational variables have the greatest influence on the relational significance of hedonic and dispositional needs in attraction and attachment to sporting events. The work supports the inclusion of communities as an additional attachment outcome.

Practical implications
– In all, 92 percent of riders were informed about the event through word of mouth (WOM) marketing, highlighting the importance this promotional technique in the awareness stage of the PCM. NMSS would be well served by capitalizing on the power of WOM.

Originality/value
– The research provides insight into predictors of fundraising efficacy. In terms of fundraising effectiveness, participants with four or more years of participation were six times more likely than first-year riders to raise $1,000 or more.

Authors: Kartsonakis Ioannis A , Koumoulos Elias P. , Karantonis Antonis , Charitidis Costas A. , Dessypris S , Monos A 
Published: October 2015

Purpose– The purpose of this paper is to perform the evaluation of copper susceptibility to corrosion in industrial cooling systems. Microstructure and defects of copper are observed, while divergences from optimum structure are discussed.Design/methodology/approach– Various types of corrosion are examined. Electrochemical techniques such as electrochemical impedance spectroscopy and potentiodynamic polarisation are applied in these materials, using corrosion inhibitors. Microscopic observations and electrochemical measurements are interpreted according to possible mechanistic scenarios.Findings– It is evident that, under specific conditions (e.g. high pH), water cooling ingredients can enhance corrosion, leading to significant copper mass loss from the inner surface of the pipe and thus leading to failure.Originality/value– Evaluation of copper corrosion in cooling industrial systems was done, as well as studies of copper corrosion in sodium chloride.
Family firms, firm characteristics, and corporate social performance
Authors: Aoi Michikazu , Asaba Shigeru , Kubota Keiichi , Takehara Hitoshi 
Published: October 2015

Purpose
– The purpose of this paper is to explore corporate social performance attained by listed family and non-family firms in Japan. They are measured by the composite CSP index and five attributes composed of employ relations, social contributions (SCs), firm security and product safety, internal governance and risk control, and environment concern.

Design/methodology/approach
– The authors employ univariate and regression analyses on the quantitatively aggregated CSP score data of Japanese firms from 2007 to 2009.

Findings
– Japan non-family firms tend to perform better than family firms in terms of attaining corporate social performance overall. Family CEOs positively affect CSP in the foods, textiles and apparels, and pharmaceutical industries as well as in retail trade, wholesale, and services industries, but negatively affect CSP in the heavy manufacturing industry. In these industries the joint effect of the percentage of family shareholdings and the fraction of family members on the board also augments the positive role played by family CEO. The findings are robust when the sample is ranked by Tobin’s q.

Research limitations/implications
– The observation period is short due to the data availability of CSP by Toyo Keizai Inc. This data covers all the listed firms which answered the questionnaire, which may also contain sample selection problems.

Practical implications
– Positive role of CEO and negative effects of shareholdings among listed family firms in Japan call for attention and corrective measures for top management and family shareholders.

Social implications
– While family firms in Japan may accumulate socioemotional wealth, they should exert more efforts to advance CSP and create social capital.

Originality/value
– This is the first comprehensive quantitative study in the field, which explored CSP of all the listed family firms vs non-family firms in Japan with large sample.
