Corporate Social Responsibility in the Process of Attracting College Graduates
Authors: Barrena‐Martínez Jesús , López‐Fernández Macarena , Márquez‐Moreno Cristina , Romero‐Fernández Pedro Miguel 
Published: May 2014

AbstractCorporate social responsibility (CSR) is acquiring great relevance in academic and professional fields as a tool which enables an increase in business competitiveness and sustainable development. Additionally, a growing number of authors have started to consider CSR as an internal capability that allows firms to attract and retain a qualified workforce. Taking into account this premise, this study has a two‐fold aim: (i) to analyse which CSR aspects are assessed higher or lower by valuable human capital such as college graduates when they decide to join a company, and (ii) to show the existence of personal and social integration factors which influence this assessment. To address these purposes, this study carried out a quantitative analysis at different Spanish universities. The results conclude that social integration factors have greater influence on the assessment of CSR and sustainable practices with regard to the processes of attracting college graduates than do personal explanatory factors.

Distributed power flow loss minimization control for future grid
Authors: Nakayama Kiyoshi , Zhao Changhong , Bic Lubomir F. , Dillencourt Michael B. , Brouwer Jack 
Published: May 2014

SummaryIn this paper, a novel decentralized algorithm is proposed to minimize power flow loss in a large‐scale future grid connecting with many real‐time‐distributed generation systems by which power flows bi‐directionally. The DC‐power loss at each link is defined as the product of resistance and the square of current that can be considered as a quadratic flow cost. We employ the notion of tie‐sets that reduces the complexity of the power flow loss problem by dividing a power network into a set of loops that forms a linear vector space on which the power loss problem can be formulated as a convex optimization problem. As finding a solution in each tie‐set enables global optimization, we realize parallel computing within a system of independent tie‐sets by integrating autonomous agents. Simulation results demonstrate the minimization of the power loss on every link by iteratively optimized power flows and show the superiority against the traditional centralized optimization scheme.

Utility of coloured hair for the detection of drugs and alcohol
Authors: Agius Ronald 
Published: May 2014

The aim of this paper is to assess the utility of coloured hair for the detection of drugs and alcohol in a large statistically significant population. The positivity rate, the 1st, 5th, 50th, 95th, and 99th percentiles of five amphetamines, cannabinoids, cocaine, four opiates, methadone, buprenorphine, seven benzodiazepines, and ethyl glucuronide (EtG) in 9488 non‐treated and 1026 cosmetically treated (dyed or bleached) authentic hair samples was compared. Analytical methods used were accredited for forensic purposes at the cut‐offs defined by the German driving licence re‐granting medical and psychological assessment (MPA) guidelines.Considering only the drug classes for which at least 10 positive samples were detected, the positivity rate in non‐treated hair was highest for alcohol (4.50%; measured using EtG at concentrations ≥ 7 pg/mg hair), followed by THC (2.00%), cocaine (1.75%), and amphetamine (0.59%). While the 1st to 99th percentile range was significantly lower for drugs in treated, compared to non‐treated hair, no significant change was observed for EtG. Additionally, no significant difference in the positivity rate was observed between treated hair and non‐treated hair for both drugs and EtG. This study is the first attempt to evaluate the influence of cosmetic treatment, mainly dying, on the positivity rate for both drugs and EtG in hair samples submitted routinely for abstinence testing and the first to indicate that dyed and eventually bleached hair is not necessarily useless in detecting drugs and/or alcohol consumption, thus making coloured hair analysis still useful, often being the only possibility to prove such misuse.

Published: May 2014

ABSTRACTObjectiveLow‐intensity exercise applied in anorexia nervosa patients has been shown to have a harmless effect on body composition and to effect short‐term improvements in muscular strength and agility. The aim of this study was to determine the effects of a high‐intensity resistance training program designed for adolescents to improve strength and agility in anorexia nervosa restricting‐type patients (AN‐R).MethodsFrom a total of 36 female patients with AN‐R, one group (intervention, n = 18) underwent a supervised high‐intensity resistance training program lasting 8 weeks, and the other group with no exercise (control, n = 18). Body weight, body mass index, whole‐body muscular strength, and agility were assessed before, after, and 4 weeks after training (detraining).ResultsLeg‐press, bench‐press, and lateral row tests improved significantly (p < 0.001) after 8 weeks of training compared with controls. Improvements were maintained after the detraining period. The training program also showed beneficial effects on agility.DiscussionA high‐intensity resistance training program adapted to the recommendations for adolescents in AN‐R patients was effective and safe, improving muscular strength in the whole body and the ability to perform daily tasks. However, long‐term maintenance of gains seems to be linked to the continuance of training or the use of a maintenance program. © 2014 Wiley Periodicals, Inc. (Int J Eat Disord 2014; 47:601–609)
Diels–Alder Reactions of Masked o‐Benzoquinones with 1‐Vinylcyclohexenes: A Short and Efficient Entry to Highly Functionalized Decahydrophenanthrene Skeleton
Authors: Niu Guang‐Hao , Hou Chieh‐Shen , Chuang Gary Jing , Wu Chi‐Phi , Liao Chun‐Chen 
Published: May 2014

AbstractMasked o‐benzoquinones (MOBs), which were generated in situ from 2‐methoxyphenols, underwent Diels–Alder reactions with 1‐vinylcyclohexenes to produce the corresponding cycloaddition products, that is, decahydrophenanthrenes along with bicyclo[2.2.2]octenones. In the former case, the MOBs serve as the dienophile, and in the later case, the 1‐vinylcyclohexenes act as the dienophile. The obtained bicyclo[2.2.2]octenones could be transformed into the corresponding decahydrophenanthrenes through a Cope rearrangement at 220 °C. Thus, these tandem reactions provide a short and efficient entry to the decahydrophenanthrene skeleton from easily available 2‐methoxyphenols.

Authors: Müller Astrid , Claes Laurence , Wilderjans Tom F. , de Zwaan Martina 
Published: May 2014

AbstractObjectiveThis study aimed to investigate temperament subtypes in obese patients.MethodsNinety‐three bariatric surgery candidates and 63 obese inpatients from a psychotherapy unit answered the Behavioral Inhibition System/Behavioral Activation System Scale (BIS/BAS), the Effortful Control subscale of the Adult Temperament Questionnaire‐Short Form (ATQ‐EC), and questionnaires for eating disorder, depressive and attention deficit hyperactivity disorder (ADHD) symptoms and completed neurocognitive testing for executive functions. Binge eating disorder and impulse control disorders were diagnosed using interviews.ResultsA latent profile analysis using BIS/BAS and ATQ‐EC scores revealed a ‘resilient/high functioning’ cluster (n = 88) showing high ATQ‐EC and low BIS/BAS scores and an ‘emotionally dysregulated/undercontrolled’ cluster (n = 68) with low ATQ‐EC and high BIS/BAS scores. Patients from the ‘emotionally dysregulated/undercontrolled’ cluster showed more eating disorder, depressive and ADHD symptoms, and poorer performance in the labyrinth task.ConclusionThe findings support the assumptions regarding the heterogeneity of obesity and the association between temperament subtypes and psychopathology.

Forecasting the Term Structure when Short‐Term Rates are Near Zero
Authors: Steeley James M. 
Published: May 2014

ABSTRACTThis paper compares the experience of forecasting the UK government bond yield curve before and after the dramatic lowering of short‐term interest rates from October 2008. Out‐of‐sample forecasts for 1, 6 and 12 months are generated from each of a dynamic Nelson–Siegel model, autoregressive models for both yields and the principal components extracted from those yields, a slope regression and a random walk model. At short forecasting horizons, there is little difference in the performance of the models both prior to and after 2008. However, for medium‐ to longer‐term horizons, the slope regression provided the best forecasts prior to 2008, while the recent experience of near‐zero short interest rates coincides with a period of forecasting superiority for the autoregressive and dynamic Nelson–Siegel models.

Assessing the Macroeconomic Forecasting Performance of Boosting: Evidence for the United States, the Euro Area and Germany
Authors: Wohlrabe Klaus , Buchen Teresa 
Published: May 2014

ABSTRACTThe use of large datasets for macroeconomic forecasting has received a great deal of interest recently. Boosting is one possible method of using high‐dimensional data for this purpose. It is a stage‐wise additive modelling procedure, which, in a linear specification, becomes a variable selection device that iteratively adds the predictors with the largest contribution to the fit. Using data for the United States, the euro area and Germany, we assess the performance of boosting when forecasting a wide range of macroeconomic variables. Moreover, we analyse to what extent its forecasting accuracy depends on the method used for determining its key regularization parameter: the number of iterations. We find that boosting mostly outperforms the autoregressive benchmark, and that K‐fold cross‐validation works much better as stopping criterion than the commonly used information criteria.

The effects of thymic stromal lymphopoietin and IL‐3 on human eosinophil–basophil lineage commitment: Relevance to atopic sensitization
Authors: Hui Claudia C. K. , Rusta‐Sallehy Sina , Asher Ilan , Heroux Delia , Denburg Judah A. 
Published: May 2014

AbstractAn important immunopathological hallmark of allergic disease is tissue eosinophilic and basophilic inflammation, a phenomenon which originates from hemopoietic progenitors (HP). The fate of HP is determined by local inflammatory cytokines that permit “in situ hemopoiesis,” which leads to the accumulation of eosinophils and basophils (Eo/B). Given that recent evidence supports a critical immunomodulatory role for thymic stromal lymphopoietin (TSLP) in allergic inflammation, as well as TSLP effects on CD34+ progenitor cytokine and chemokine secretion, we investigated the role of TSLP in mediating eosinophilo‐ and basophilopoiesis, the mechanisms involved, and the association of these processes with atopic sensitisation. In the studies presented herein, we demonstrate a direct role for TSLP in Eo/B differentiation from human peripheral blood CD34+ cells. In the presence of IL‐3, TSLP significantly promoted the formation of Eo/B colony forming units (CFU) (including both eosinophils and basophils) from human HP (HHP), which was dependent on TSLP–TSLPR interactions. IL‐3/TSLP‐stimulated HHP actively secreted an array of cytokines/chemokines, key among which was TNFα, which, together with IL‐3, enhanced surface expression of TSLPR. Moreover, pre‐stimulation of HHP with IL‐3/TNFα further promoted TSLP‐dependent Eo/B CFU formation. HHP isolated from atopic individuals were functionally and phenotypically more responsive to TSLP than those from nonatopic individuals. This is the first study to demonstrate enhanced TSLP‐mediated hemopoiesis ex vivo in relation to clinical atopic status. The capacity of HHP to participate in TSLP‐driven allergic inflammation points to the potential importance of “in situ hemopoiesis” in allergic inflammation initiated at the epithelial surface.
BANK DIVIDENDS, REAL GDP GROWTH AND DEFAULT RISK
Authors: Kanas Angelos 
Published: May 2014

ABSTRACTWe reveal evidence that the US aggregate bank dividends exercise a causal impact on the US real GDP growth during the period from the introduction of the Prompt Corrective Action framework in 1992 until the outburst of the subprime mortgage market crisis in 2007. Over this period, the positive signalling effects of bank dividends outperform the negative effect of dividends on default risk. During the pre‐Prompt Corrective Action and the recent post‐2007 periods, bank dividends do not affect GDP growth. This regime‐dependent relation is due to an asymmetric role of bank default risk. These findings are of interest to bank regulators in reassessing the role of bank dividends within Basel III and carry important policy implications as bank dividends constitute an important tool available to policy makers for strengthening real activity.

THE IMPACT OF FALLEN ANGELS ON INVESTMENT GRADE CORPORATE BONDS PORTFOLIOS: EVIDENCE FROM THE EUROPEAN MARKET
Authors: Bolognesi Enrica , Ferro Marianna , Zuccheri Andrea 
Published: May 2014

ABSTRACTThis work examines the impact on the price of corporate bonds denominated in Euro of a downgrade to high yield announced by Standard & Poor's and/or Moody's Investors Service. In particular, we observe the bond price behaviour around three events. The first event is the first downgrade announcement from one of the rating agencies, and we find significant cumulative abnormal returns before and at around the event. The second event is the downgrade announcement by the second rating agency: in this case, the security becomes a fallen angel and must leave the institutional portfolios constrained to investment grade (IG) securities. We record again a significant negative price reaction but larger than in the previous case and significantly higher when preceded by a widening of the credit spread in the corporate bonds market. Broadening the existing literature, we perform a third event study, focused on the subsequent bond deletion from an IG benchmark. In this case, our results show positive and significant excess returns after the month‐end index rebalancing, revealing a price reversal pattern of the fallen angel after its release from the index. This price rebound is the higher, whereas the stronger was the bond price pressure at the downgrade announcement. These insights offer some practical guideline for those professionals that manage IG and high‐yield portfolios. Copyright © 2014 John Wiley & Sons, Ltd.

Published: May 2014

AbstractBACKGROUNDThis study investigation was carried out to obtain better quality biodiesel from robust biomass, Scenedesmus sp. through in situ transesterification with acid catalysis.RESULTSThe overall biodiesel yield from this process was estimated as c. 85 (% w/w) based on the theoretically maximum production yield of 69.36 (% w/w) from total lipids in the biomass, compared with 64 (%, w/w) from a conventional Taguchi extraction process. The quality of this biodiesel was analyzed by FT‐IR and 1H‐NMR, showing very similar characteristics to other algal biodiesel. Fatty acid methyl ester (FAME) conversion yield was obtained as 96.5%, which was higher than those from conventional transesterification processes. The result of thermogravimetric analysis (TGA) was 99.99% volatile yield and 0.01% ash, which was also better than those from other algal biodiesel. This biodiesel showed 37.95 MJ kg−1 of higher calorific value (HCV) and 23.92 MJ kg−1 of lower calorific value (LHV), respectively.CONCLUSIONThe results proved that the biodiesel from Scenedesmus sp. through a simple and economic process had high quality and also fulfilled most of the requirements of ASTM D6751 or EN 14214 for biodiesel. © 2014 Society of Chemical Industry

Published: May 2014

AbstractBACKGROUNDMicrobial electrolysis cells (MECs) have been considered a promising approach for hydrogen production from renewable biomass. The optimization of the cathode catalyst is important in the study of MECs. Based on the hydrogen production rate (Q) and the chemical oxygen demand (COD) removal as the evaluation standards, this research focused on the use of the polyaniline (PANI)/multi‐walled carbon nanotube (MWCNT) composites as the cathode catalysts to replace platinum (Pt) in a single‐chamber membrane‐free MEC.RESULTSScanning electron microscopy (SEM) and linear sweep voltammograms (LSV) were used to evaluate the morphology and electrocatalytic activity of the cathodes. At an applied voltage of 1.0 V, the MEC with 75% wt PANI/MWCNTs cathodes achieved a hydrogen production rate of 1.04 m3 m−3 d−1 at a current density of 163 A m−3, a coulombic efficiency of 47.2%, a cathodic hydrogen recovery of 56.7%, a COD removal of 88%, and an electrical energy efficiency based on an electricity input of 89%, which was comparable with that of a Pt/C cathode.CONCLUSIONSThe PANI/MWCNTs cathodes developed achieved a performance comparable with that of the Pt/C cathode in terms of the hydrogen production rate. The PANI/MWCNTs composites used as cathodic catalysts to replace Pt/C substantially reduced the cost of the MECs. © 2014 Society of Chemical Industry
Assessment of modularity in the urodele skull: An exploratory analysis using ossification sequence data
Authors: Laurin Michel 
Published: May 2014

ABSTRACTThe potential presence of developmental modules is studied in the urodele skull using several classical statistical methods that have not previously been used in this context. Principal component analysis (PCA) of ossification sequence data on 21 bones in 21 extant urodele species suggests the presence of up to four developmental modules, but examination of statistically significant correlations using phylogenetic independent contrasts (PIC) and correcting for multiple tests using the false discovery rate suggests the presence of only two modules of uneven size and of two bones that may not be part of these modules. Thus, PCA does not appear to be a reliable method to investigate modularity; direct investigation of statistically significant correlations using PIC or other phylogeny‐informed methods is recommended. A binomial test of the distribution of significant correlations between characters shows significant heterogeneity, which suggests that modularity is indeed present in the data. A cluster analysis gives inconsistent results that apparently do not reflect developmental modules. The data include a phylogenetic signal, as shown by a permutation‐based test with squared change parsimony, but this is detectable only when the whole matrix is analyzed, and a plot of the tree onto developmental space through Evolutionary PCA shows that homoplasy is pervasive. Evolutionary rates between characters vary about 90‐fold. Canonical variates analyses suggest that obligatorily neotenic urodeles may be discriminated from other urodeles on the basis of cranial ossification sequence data.J. Exp. Zool. (Mol. Dev.

Blast‐induced rock fracture near a tunnel
Authors: Xu Ling , Schreyer Howard , Sulsky Deborah 
Published: May 2014

SUMMARYDamage in the form of cracks is predicted to assess the susceptibility of a tunnel to failure due to a blast. The material‐point method is used in conjunction with a decohesive failure model as the basis for the numerical simulations. The assumption of a cylindrical charge as the source for the blast allows the restriction of plane strain and two‐dimensional analyses. In the simulation, a further restriction of a single pressure pulse is used as the source of stress waves that are reflected and refracted after reaching the free surface of the tunnel wall. Three critical zones of significant cracking in the vicinity of a tunnel are identified as potential contributors to tunnel failure. Copyright © 2014 John Wiley & Sons, Ltd.
How women manage their type 1 diabetes during the menopausal transition: a qualitative study using a grounded theory approach
Authors: Mackay Liz , Horsburgh Dorothy , Kilbride Lynn 
Published: May 2014

AbstractThis study aimed to explore the experiences of women with type 1 diabetes during the menopausal transition using a grounded theory approach and, from the data, develop a substantive theory with implications for service users and service providers.A qualitative exploratory research framework was employed using a grounded theory approach. Data were collected from 10 participants using transcribed audiotaped semi‐structured interviews and field notes. The transcripts, audio recordings and field notes were reviewed and a coding process facilitated data analysis. This approach enabled themes to emerge from the data and ultimately a theory.A wide range of conceptions was revealed. Data are presented in seven categories that reflect the experience of the subjects: ‘Blank wall’ (relates to the lack of information regarding menopause and diabetes); ‘Juggling game’ (relates to glycaemic control); Anxiety and fear; ‘Haywire’ (relates to the signs and symptoms of menopausal transition); Treating symptoms; Depression and mood; and ‘I'm old’ (relates to ageing and mortality).A substantive theory emerged. Absence of information regarding the menopause and its impact on type 1 diabetes (‘Blank wall’) was identified as the main problem facing women with type 1 diabetes during their menopausal transition. The findings could enable practitioners to identify the types of information, advice and support that should be made available to these women, and contribute to the limited knowledge base currently available. The findings indicate also that further research into this under‐studied but important area of diabetes care is required.
