BackgroundIn this study we investigated whether an Internet-based computerized cognitive behavioral therapy (iCBT) program can decrease the risk of DSM-IV-TR major depressive episodes (MDE) during a 12-month follow-up of a randomized controlled trial of Japanese workers.MethodParticipants were recruited from one company and three departments of another company. Those participants who did not experience MDE in the past month were randomly allocated to intervention or control groups (n = 381 for each). A 6-week, six-lesson iCBT program was provided to the intervention group. While the control group only received the usual preventive mental health service for the first 6 months, the control group was given a chance to undertake the iCBT program after a 6-month follow-up. The primary outcome was a new onset of DSM-IV-TR MDE during the 12-month follow-up, as assessed by means of the web version of the WHO Composite International Diagnostic Interview (CIDI), version 3.0 depression section.ResultsThe intervention group had a significantly lower incidence of MDE at the 12-month follow-up than the control group (Log-rank χ2 = 7.04,p < 0.01). The hazard ratio for the intervention group was 0.22 (95% confidence interval 0.06–0.75), when estimated by the Cox proportional hazard model.ConclusionsThe present study demonstrates that an iCBT program is effective in preventing MDE in the working population. However, it should be noted that MDE was measured by self-report, while the CIDI can measure the episodes more strictly following DSM-IV criteria.

Abstract:For endozoochorous seed dispersal systems, the extant dung beetle assemblage at seed deposition sites may influence site suitability as burial activity may change the probability that seeds germinate and seedlings establish. This study tested if the different conditions of the two main seed-deposition habitats of a western lowland gorilla population of south-east Cameroon (sleeping sites and old secondary forest) influenced dung beetle assemblages and consequently the seed relocation patterns. In March 2012, in both habitats, burial patterns (proportion and depth) were described in eight stations based on two 300-g experimental faeces with known number of Uapaca spp. seeds (N = 75) left for 48 h, and beetle assemblages were described based on one 48h-dung-baited pitfall trapping session in five of these stations. To assess the impact of burial pattern on seedling emergence, Uapaca seedling emergence trials were performed in a nursery (75 seeds per depth treatment). Assemblage at sleeping sites had a higher species richness (non-significant) and was significantly more abundant than in old secondary forests. Conversely, significantly more seeds were buried in old secondary forests than sleeping sites and at significantly greater depths (mean: 14.9 cm vs. 8.7 cm). As trials suggested that burial depth ≥7 cm prevented Uapaca seedling emergence, dung beetles are assumed to induce seed loss more strongly in old secondary forests than sleeping sites (20.5% vs. 6.7% of initial seed crop). The demonstration that dung beetles may exert a negative influence on seed fate overall, and that the degree to which this occurs may vary depending on habitat, highlights the complexity in determining the suitability of deposition sites for recruitment.

AbstractObjectiveTo assess the prevalence of household food insecurity (FI) in France and to describe its associations with socio-economic factors, health behaviours, diet quality and cost (estimated using mean food prices).DesignCross-sectional nationally representative survey. FI was assessed using an adapted version of the US Department of Agriculture’s Food Insufficiency Indicator; dietary intake was assessed using a 7 d open-ended food record; and individual demographic, socio-economic and behavioural variables were assessed using self-administered questionnaires and interviews. Individuals experiencing FI were compared with food-secure individuals, the latter being divided into four categories according to quartiles of their income per consumption unit (FS1 to FS4). Differences among categories were analysed usingχ2tests, ANOVA and tests for trend.SettingIndividual and National Dietary Survey (INCA2), 2006–2007.SubjectsAdults aged 18–79 years (n2624).ResultsIndividuals experiencing FI represented 12·2 % of the population. They were on average younger, more frequently women and single parents with children compared with those in the other four categories. Their mean income per consumption unit was higher than that in the FS1 category, but they reported poorer material and housing conditions. The prevalence of smoking and the mean daily time spent watching television were also higher in the FI category. No significant difference among categories was found for energy intake, but mean intakes of fruits, vegetables and fish were lower, and diet quality was slightly but significantly poorer in the FI category. Daily diet cost was also lower in the FI category.ConclusionsFrance is not spared by FI. FI should be routinely monitored at the national level and research should be promoted to identify effective strategies to reduce nutrition inequalities in France.
Plectoneme tip bubbles: Coupled denaturation and writhing in supercoiled DNA
Authors: Matek Christian , Ouldridge Thomas E. , Doye Jonathan P. K. , Louis Ard A. 
Published: January 2015

AbstractWe predict a novel conformational regime for DNA, where denaturation bubbles form at the tips of plectonemes and study its properties using coarse-grained simulations. For negative supercoiling, this regime lies between bubble-dominated and plectoneme-dominated phases and explains the broad transition between the two observed in experiment. Tip bubbles cause localisation of plectonemes within thermodynamically weaker AT-rich sequences and can greatly suppress plectoneme diffusion by a pinning mechanism. They occur for supercoiling densities and forces that are typically encountered for DNA in vivo and may be exploited for biological control of genomic processes.
Modulation of folding energy landscape by charge–charge interactions: Linking experiments with computational modeling
Authors: Tzul Franco O. , Schweiker Katrina L. , Makhatadze George I. 
Published: January 2015

Significance
Quantitative understanding of how individual interactions contribute to the kinetics and thermodynamics of protein folding is critical for deciphering the underlying molecular mechanisms that define the energy folding landscape. We applied a structure-based model that explicitly accounts for the interactions between charges, to folding–unfolding of four different protein pairs: rationally stabilized, via optimization of surface charge–charge interactions, variants, and respective wild types. First, we established that the models predict both thermodynamic and kinetic differences observed experimentally for all four studied protein pairs. Second, we used the results of the computational modeling to provide a molecular level explanation of how optimization of charge–charge interactions leads to an increase in the folding rates of designed variants, without changes in the unfolding rates.

Significance
The human EGF receptor (EGFR/HER) family plays critical roles in tumor progression. Therefore, several therapies intercepting these receptors were developed and clinically approved. Importantly, patients treated with such therapeutics often develop resistance, and in some cases this resistance has been associated with activation of HER3. Potentially, HER3 blockade might overcome patient resistance. Hence, antibodies to HER3 have been developed by us and other researchers. However, it has remained unclear which antibody attributes are required for effective tumor inhibition. To address this issue, we generated several monoclonal antibodies, which were tested in vitro and in tumor-bearing animals. Our results suggest that anti-HER3 antibodies able to intercept stroma–tumor interactions, as well as accelerate HER3 degradation, might inhibit tumor growth better than other antibodies.
Philosophical perspectives on school effectiveness and school improvement
Authors: White John 
Published: January 2015

ABSTRACTResearch on school effectiveness and on school improvement has become more important in recent years as politicians and other policy‐makers have made use of the findings. It is argued here that there are a number of flaws in the design of such research (for example, if factors and outcomes are logically related, then empirical investigation becomes irrelevant). Furthermore, the sidelining of long‐term goals of education by researchers in these fields has the effect of marginalizing what is central to any discussion of educational practice (even if these goals cannot be measured). The article concludes with a plea both for more reflection on these aims and closer collaboration with philosophers of education.
The field of photographic education
Authors: Newbury Darren 
Published: January 2015

ABSTRACTThis paper uses Bourdieu's concept of the field as a method of analysis of contemporary developments in photographic education. The paper begins by sketching the outline and some of the contradictions of contemporary photographic educational practice. A visual model of photographic education as a field is offered and its benefits and limitations considered. The paper then considers in more detail two contemporary developments: the debate over the content and purpose of higher education in photography; and the run‐up to the introduction of National Vocational Qualifications in photography. In conclusion it is argued that the forces that are currently holding photographic education together are coming under considerable pressure from new developments in visual and media education, and that a reconfiguration of the field is both likely and desirable.
Indigenous Feminisms
Authors: Barker Joanne 
Published: January 2015

Abstract
Feminism occupies a rich and meaningful, albeit uncomfortable, history in Indigenous communities in the United States. This chapter examines that history in relation to the women’s suffrage and civil rights movements. It argues that in deflection and invitation of feminist politics during these movements, Indigenous scholars, activists, and artists (not necessarily mutually exclusive) demonstrate the primacy of sovereignty and self-determination in their understandings of how feminism is or is not relevant to them, clarifying the constitutive role of US imperialism, racism, and sexism in how feminism has been (dis)articulated. At the same time, it argues that Indigenous feminism has asserted the polity of the Indigenous: the unique governance, territory, and culture of an Indigenous people in a system of (non)human relationships and responsibilities to one another. In doing so, Indigenous feminisms rearticulate the futurity of indigeneity in political coalition with non-Indigenous peoples against the ongoing social forces of US imperialism, racism, and sexism.
The Life of the Soviet Worker
Authors: Smith Mark B. 
Published: January 2015

Abstract
The Soviet Union was the workers’ state and worker culture, broadly defined, coloured the whole of the Soviet experience. At the centre of the most transformative Soviet project of all, Stalin’s industrial revolution of 1928–41, workers benefited from specific privileges and from affirmative action, though they also suffered the misery of rapid industrial change. After 1953, they enjoyed a heyday of modest material advances and moral certainties, marked by the sense that society respected at least some of their values and would do so forever. But this sense was not shared by all Soviet workers, and lifestyles varied by industry, skill level, and region. And the heyday faded as shortages became increasingly difficult to endure, and then ended, as Gorbachev’s reforms destroyed the comforts that remained. A positive worker identity, but not a coherent class consciousness, survived through to perestroika, and helped to sustain the dynamic of Soviet history.
Electronic Dance Music in the Dubstep Era
Authors: D’Errico Mike 
Published: January 2015

Abstract
The first decade of the 2000s witnessed the transnational proliferation of dubstep, an electronic dance music style that quickly became ubiquitous across media platforms and audiences. This article traces the history of dubstep, from its origins in the underground clubs of south London to its presence on the silver screen of Hollywood films. First, the transnational musical relationship between England and the United States is interrogated, in an effort to highlight the significance of “local” scenes in light of increasing globalization. Second, the article examines the use of dubstep across media platforms, positing the more general cultural practice of technological mediation in electronic music as a gendered practice.
Satisfaction in Open Access Versus Traditional Referral for Upper Endoscopy in Children
Authors: Isaac Daniela Migliarese , Persad Rabin , Huynh Hien Q. , Shirton Leanne , Turner Justine M. 
Published: January 2015

ABSTRACTObjectives:In traditional access endoscopy (TAE), patients are booked for endoscopy following a gastroenterology clinic assessment. In contrast, open access endoscopy (OAE) patients are seen for the first time on the day of the procedure, providing same day procedural consent. Controversy exists over the use of OAE in adults, both with the consent process and with patient satisfaction. No literature exists describing satisfaction with OAE in pediatrics. We therefore aimed to assess pediatric patient and caregiver satisfaction in OAE compared with TAE.Methods:Consecutive pediatric patients, and their caregivers, undergoing elective upper endoscopy from May to December 2012 at the Stollery Children's Hospital (Edmonton, Alberta, Canada) were consented for a cross‐sectional survey. Seven preprocedure and 5 postprocedure questions were completed regarding mood and satisfaction with the wait time and the information provided. Group demographics and endoscopy wait times were collected.Results:Median wait time with OAE was less compared with TAE (57 days vs 196 days, P < 0.001). OAE patients reported worse mood preprocedure than TAE patients (35.3% vs 10.7%, P = 0.046). OAE caregivers and patients reported more mood disturbance if required to wait longer for endoscopy by attending clinic preprocedure (OAE caregivers 62.2%, OAE patients 64.7%).Conclusions:OAE is associated with worse preendoscopy patient mood; however, children and caregivers seem concerned about longer wait times associated with TAE. Given the significantly shorter wait times in OAE, identifying methods to minimize present limitations of OAE will be useful to improve clinical practices in pediatric gastroenterology.

Published: January 2015

ABSTRACTObjectives:Health‐related quality of life (HRQOL) is an important, but understudied construct in pediatric inflammatory bowel disease. Family level predictors of HRQOL have been understudied as are the mechanisms through which disease activity affects HRQOL. The present study examines the relation between a family level factor (parenting stress) and HRQOL in youth with Crohn disease. Parenting stress is examined as a mechanism through which disease activity affects HRQOL.Methods:A total of 99 adolescents with Crohn disease and their parents were recruited across 3 sites. Adolescents completed the IMPACT‐III (inflammatory bowel disease–specific HRQOL). Parents completed the Pediatric Inventory for Parents, a measure of medically related parenting stress that assesses stress because of the occurrence of medical stressors and stress because of the perceived difficulty of stressors. Disease activity was obtained from medical records.Results:Parenting stress because of the occurrence of medical stressors partially mediated the disease severity–HRQOL relation, reducing the relation between these variables from 49.67% to 31.58% (B = −0.56,P< 0.0001). Bootstrapping analysis confirmed that the indirect effect of disease severity on HRQOL via parenting stress significantly differed from zero. Parenting stress because of the perceived difficulty of medical stressors partially mediated the disease severity–HRQOL relation, reducing the relation from 49.67% to 30.29% (B = −0.55,P< 0.0001). The indirect effect was confirmed via bootstrapping procedures.Conclusions:As disease severity increased, parenting stress also increased, and adolescent HRQOL decreased. Parenting stress should be considered and assessed for along with medical factors as part of a comprehensive approach to improve HRQOL in adolescents with Crohn disease.
The impediments to the competitiveness of the rail industry in Australia
Authors: Ghaderi Hadi , Fei Jiangang , Cahoon Stephen 
Published: January 2015

Purpose
– The purpose of this paper is to identify current impediments to the competitiveness of the rail industry in the Australian non-bulk freight market.

Design/methodology/approach
– A systematic literature review was adapted to identify the impediments and challenge themes from 1,081 studies available on the Australian rail industry. To select the studies relevant to the research question, a tollgate criterion was then deployed. Impediments were identified by a structured data synthesis process and a heuristic algorithm was developed to explore the possible relationships between the impediments and challenges.

Findings
– Four major themes are apparent, each of which presents the rail industry with challenges in the non-bulk freight market. “Infrastructural inefficiencies and the need for further integration” was ranked as the main rail industry challenge, while “environmental concerns and the associated costs of externalities” was the least. In addition, across the four themes data synthesis identified 43 impediments from purely policy related to technical and operational aspects.

Research limitations/implications
– The major implication of this review is the identification of impediments that have no linkage to the four industry challenges as revealed by stakeholders in the literature. That means that the rail industry has been dealing with a number of issues that have not been explored and studied in depth either by practitioners or academics. The underlying elements of impediments in this group are perceived as managerial, organisational and leadership factors. The rail industry has failed to manage its organisational ties across the system, both horizontally and vertically. This issue has been intensified as the result of complex interactions between different transport modes and operators associated with the non-bulk freight sector.

Originality/value
– For the first time in the Australian context, this study provides an en masse and summarised picture of impediments to the competitiveness of the rail industry in the non-bulk freight market by systematically reviewing the reports generated by different stakeholders in the last ten years. The outcomes will assist the rail industry and government to understand impediments impacting on the quality of rail freight services that may lead to collaboration on decision-making and investment strategies.
Design and testing of a magnetic suspension for a 90° horizontal bend conveyor
Authors: Fabbri Massimo , Ribani Pier Luigi , Zuffa Davide 
Published: January 2015

Purpose
– A conveyor device is studied with the aim to reduce the friction between the inner surface of the beam and the chain. The lower is the friction between the chain and the beam, the lower is the surface wear. The magnetic repulsion force among permanent magnets (PMs) placed on the beam and on the chain is utilized to reduce friction. The paper aims to discuss these issues.

Design/methodology/approach
– The considered magnetic suspension is realized with PMs in repulsive configuration; it is designed by solving a constrained optimization problem, with reference to the geometry of the 90° horizontal bend FlexLink WL322 conveyor. Flux density field and its gradient are evaluated using volume integral equation method, allowing to calculate the forces acting on the chain and the stiffness of the magnetic suspension.

Findings
– The magnetic suspension prototype was manufactured and tested. The experimental and calculated values of the forces acting on the chain compares well. A stable horizontal equilibrium of the chain was obtained during both static and dynamical tests.

Research limitations/implications
– The quasi-static model used neglects the dynamical interactions among the elements of the chain, the PMs and loads weight during motions and the eddy current losses in the aluminium beam. However the dynamical tests on the prototype show that the chain motion is regular up to the nominal velocity all along the conveyor with the exception of the trailing edge of the 90° curve.

Practical implications
– The tests on the prototype show the possibility of a removal or at least a reduction of the friction force between the chain and the inner side of the beam by means of a passive magnetic suspension. As a consequence a reduction of noise and vibrations and an increase of the mean-time-to-failure is expected.

Originality/value
– Prototype testing shows that the unavoidable vertical instability of the magnetic forces has no practical consequence since, reducing the allowed vertical gap, the chain is stabilized by the gravitational force.
