Life satisfaction trajectories of elderly women living in Switzerland: an age–period–cohort analysis
Authors: BURTON-JEANGROS CLAUDINE , ZIMMERMANN-SLOUTSKIS DORITH 
Published: September 2014

ABSTRACTOld age isa prioria vulnerable stage of the lifecourse. Quality of life can be expected to decline in older age due to loss, isolation, and declining cognitive and physical abilities. The purpose of this study was to investigate the distribution, prevalence and trajectory of life satisfaction (LS) as a measure of quality of life among Swiss elderly women. We also assessed the impact of different social determinants on LS within the age categories of the ‘young old’ and the ‘old old’ across different cohorts. Using the Swiss Household Panel survey data, analyses of LS distribution and trajectories were conducted for 1,402 women aged 65–84 years. About 50 per cent of elderly women in Switzerland were very satisfied with their lives. The mean LS score and the prevalence of satisfied women were lower in more recent cohorts of identical ages. However, their LS remained more stable over ageing than was the case in former cohorts. High education, satisfaction with income, social support, living with a partner and good self-perceived health were all positive and significant predictors of LS. Longitudinal analyses allowed the ageing process net of cohort and period effects to be disentangled and the assessment of the influence of both social determinants and within-individual psychological traits on the self-evaluation of LS.

Authors: Laranjo Sérgio , Oliveira Mário , Trigo Conceição 
Published: September 2014

AbstractLeft anterior accessory pathways are considered to be rare findings. Catheter ablation of accessory pathways in this location remains a challenging target, and few reports about successful ablation of these accessory pathways are available. We describe our experience regarding a case of a manifest left anterior accessory pathway ablation using radiofrequency energy at the junction of the left coronary cusp with the non-coronary cusp.
Isolation of the left subclavian artery: a rare aortic arch anomaly
Authors: Saktheeswaran Mahesh K. , Krishnamoorthy Kavaserry Mahadevan , Sivasankaran Sivasubramonian 
Published: September 2014

AbstractIsolation of the left subclavian artery is a rare anomaly associated with acyanotic CHDs and right aortic arch. This condition can be asymptomatic or can present with neurological and left upper-limb ischaemic symptoms; it does not form a vascular ring. Treatment options include implantation of the subclavian artery to the aortic arch vessels and closure of the patent ductus arteriosus to prevent pulmonary run off. Here we describe a child who was incidentally detected to have this condition during evaluation of atrial septal defect for device closure.
Machines as Persons?
Authors: Cherry Christopher 
Published: September 2014

I begin, as I shall end, with fictions.In a well-known tale, The Sandman, Hoffmann has a student, Nathaniel, fall in love with a beautiful doll, Olympia, whom he has spied upon as she sits at a window across the street from his lodgings. We are meant to suppose that Nathaniel mistakes an automaton for a human being (and so a person). The mistake is the result of an elaborate but obscure deception on the part of the doll's designer, Professor Spalanzani. Nathaniel is disabused quite by accident when he over-hears a quarrel between Spalanzani, who made Olympia's clockwork, and the sinister Coppelius, who contributed the eyes (real eyes, it seems).
ON SOLUTIONS TO NONHOMOGENEOUS ALGEBRAIC DIFFERENTIAL EQUATIONS AND THEIR APPLICATION
Authors: LIAO LIANG-WEN , YE ZHUAN 
Published: September 2014

AbstractWe consider solutions to the algebraic differential equation $\def \xmlpi #1{}\def \mathsfbi #1{\boldsymbol {\mathsf {#1}}}\let \le =\leqslant \let \leq =\leqslant \let \ge =\geqslant \let \geq =\geqslant \def \Pr {\mathit {Pr}}\def \Fr {\mathit {Fr}}\def \Rey {\mathit {Re}}f^nf'+Q_d(z,f)=u(z)e^{v(z)}$, where $Q_d(z,f)$ is a differential polynomial in $f$ of degree $d$ with rational function coefficients, $u$ is a nonzero rational function and $v$ is a nonconstant polynomial. In this paper, we prove that if $n\ge d+1$ and if it admits a meromorphic solution $f$ with finitely many poles, then $$\begin{equation*} f(z)=s(z)e^{v(z)/(n+1)} \quad \mbox {and}\quad Q_d(z,f)\equiv 0. \end{equation*}$$ With this in hand, we also prove that if $f$ is a transcendental entire function, then $f'p_k(f)+q_m(f)$ assumes every complex number $\alpha $, with one possible exception, infinitely many times, where $p_k(f), q_m(f)$ are polynomials in $f$ with degrees $k$ and $m$ with $k\ge m+1$. This result generalizes a theorem originating from Hayman [‘Picard values of meromorphic functions and their derivatives’, Ann. of Math. (2)70(2) (1959), 9–42].
REMARKS ON BIANCHI SUMS AND PONTRJAGIN CLASSES
Authors: LABBI MOHAMMED LARBI 
Published: September 2014

AbstractWe use the exterior and composition products of double forms together with the alternating operator to reformulate Pontrjagin classes and all Pontrjagin numbers in terms of the Riemannian curvature. We show that the alternating operator is obtained by a succession of applications of the first Bianchi sum and we prove some useful identities relating the previous four operations on double forms. As an application, we prove that for a $\def \xmlpi #1{}\def \mathsfbi #1{\boldsymbol {\mathsf {#1}}}\let \le =\leqslant \let \leq =\leqslant \let \ge =\geqslant \let \geq =\geqslant \def \Pr {\mathit {Pr}}\def \Fr {\mathit {Fr}}\def \Rey {\mathit {Re}}k$-conformally flat manifold of dimension $n\geq 4k$, the Pontrjagin classes $P_i$ vanish for any $i\geq k$. Finally, we study the equality case in an inequality of Thorpe between the Euler–Poincaré characteristic and the $k{\rm th}$ Pontrjagin number of a $4k$-dimensional Thorpe manifold.

AbstractStomatocytes are polymersomes with an infolded bowl-shaped architecture. This internal cavity is connected to the outside environment via a small ‘mouth’ region. Stomatocytes are assembled from diamagnetic amphiphilic block-copolymers with a highly anisotropic magnetic susceptibility, which permits to magnetically align and deform the polymeric self-assemblies. Here we show the reversible opening and closing of the mouth region of stomatocytes in homogeneous magnetic fields. The control over the size of the opening yields magneto-responsive supramolecular valves that are able to reversibly capture and release cargo. Furthermore, the increase in the size of the opening is gradual and starts at fields below 10 T, which opens the possibility of using these structures for delivery and nanoreactor applications.
Improvements are Needed in Reporting of Accuracy Studies for Diagnostic Tests Used for Detection of Finfish Pathogens
Authors: Gardner Ian A. , Burnley Timothy , Caraguel Charles 
Published: September 2014

Abstract
Indices of test accuracy, such as diagnostic sensitivity and specificity, are important considerations in test selection for a defined purpose (e.g., screening or confirmation) and affect the interpretation of test results. Many biomedical journals recommend that authors clearly and transparently report test accuracy studies following the Standards for Reporting of Diagnostic Accuracy (STARD) guidelines (www.stard-statement.org). This allows readers to evaluate overall study validity and assess potential bias in diagnostic sensitivity and specificity estimates. The purpose of the present study was to evaluate the reporting quality of studies evaluating test accuracy for finfish diseases using the 25 items in the STARD checklist. Based on a database search, 11 studies that included estimates of diagnostic accuracy were identified for independent evaluation by three reviewers. For each study, STARD checklist items were scored as “yes,” “no,” or “not applicable.” Only 10 of the 25 items were consistently reported in most (≥80%) papers, and reporting of the other items was highly variable (mostly between 30% and 60%). Three items (“number, training, and expertise of readers and testers”; “time interval between index tests and reference standard”; and “handling of indeterminate results, missing data, and outliers of the index tests”) were reported in less than 10% of papers. Two items (“time interval between index tests and reference standard” and “adverse effects from testing”) were considered minimally relevant to fish health because test samples usually are collected postmortem. Modification of STARD to fit finfish studies should increase use by authors and thereby improve the overall reporting quality regardless of how the study was designed. Furthermore, the use of STARD may lead to the improved design of future studies.

Perceptual‐cognitive skill training and its transfer to expert performance in the field: Future research directions
Authors: Broadbent David P. , Causer Joe , Williams A. Mark , Ford Paul R. 
Published: September 2014

AbstractPerceptual‐cognitive skills training provides a potentially valuable method for training athletes on key skills, such as anticipation and decision‐making. It can be used when athletes are unable to physically train or are unable to experience repeated key situations from their sport. In this article, we review research on perceptual‐cognitive skills training and describe future research areas focusing on a number of key theories and principles. The main aim of any training intervention should be the efficacy of retention and transfer of learning from training to field situations, which should be the key consideration when designing the representative tasks used in perceptual‐cognitive skills training. We review the principles that seek to create practice tasks that replicate those found in the field, so as to increase the amount of transfer that occurs. These principles are perception–action coupling, the contextual interference effect and contextual information, which suggest there should be a high level of similarity between training and real‐life performance when designing perceptual‐cognitive skills training. In the final section, we discuss the transfer of retained skill acquisition from perceptual‐cognitive skills training to field performance, which we suggest to be the key area for future research in this area.
Abnormal X Chromosome Inactivation in Females with Major Psychiatric Disorders
Authors: Ji Baohu , Higa Kerin K. , Kelsoe John R. , Zhou Xianjin 
Published: September 2014

AbstractBipolar disorder, major depression and schizophrenia are severe brain disorders. No biological hallmark has been identified for any of these disorders. Here, we report that abnormal X chromosome inactivation (XCI) often presents in lymphoblastoid cells of female patients with different major psychiatric disorders in the general population. X chromosome inactivation is well preserved in human lymphoblastoid cells.XIST,KDM5C,and other X-linked genes are over-expressed in the lymphoblastoid cells of female patients, suggesting an abnormal XCI. Trimethylation of lysine 27 on histone 3 (H3K27me3) is significantly increased at bothXISTandKDM5Cgene loci. We found thatXISTandKDM5Cexpression can be used as a potential diagnostic hallmark for major psychiatric disorders in a large sub-population of female patients. Preliminary studies also suggest an increasedXISTexpression in postmortem brains from female patients with schizophrenia, bipolar disorder, and major depression. An increased gene dosage from some X-linked genes may contribute to the development of psychiatric disorders, as functional disomy of partial X chromosome have been suggested to cause mental retardation and other developmental abnormalities. Additionally, patients with Klinefelter syndrome (XXY) or Triple X syndrome (XXX) frequently display psychiatric disorders due to an extra X chromosome. Mutation of theKDM5Cgene was reported to cause X-linked syndromic mental retardation. Our studies suggest that abnormal X chromosome inactivation could play a causal role in development of major psychiatric disorders in females. Correction of abnormal X chromosome inactivation may prevent and/or cure major psychiatric disorders in a sub-population of female patients in the future.
Rapid Identification of a Natural Knockout Allele of ARMADILLO REPEAT-CONTAINING KINESIN1 That Causes Root Hair Branching by Mapping-By-Sequencing

Published: September 2014

Abstract
In Arabidopsis (Arabidopsis thaliana), branched root hairs are an indicator of defects in root hair tip growth. Among 62 accessions, one accession (Heiligkreuztal2 [HKT2.4]) displayed branched root hairs, suggesting that this accession carries a mutation in a gene of importance for tip growth. We determined 200- to 300-kb mapping intervals using a mapping-by-sequencing approach of F2 pools from crossings of HKT2.4 with three different accessions. The intersection of these mapping intervals was 80 kb in size featuring not more than 36 HKT2.4-specific single nucleotide polymorphisms, only two of which changed the coding potential of genes. Among them, we identified the causative single nucleotide polymorphism changing a splicing site in ARMADILLO REPEAT-CONTAINING KINESIN1. The applied strategies have the potential to complement statistical methods in high-throughput phenotyping studies using different natural accessions to identify causative genes for distinct phenotypes represented by only one or a few accessions.
Supply chain risk management dimensions in Indian automobile industry
Authors: Kumar Sharma Satyendra , Bhat Anil 
Published: September 2014

Purpose
– Globalization and outsourcing have rendered Indian automotive companies more vulnerable to supply chain (SC) risks. Consequently, companies adopt different supply chain risk management (SCRM) strategies to mitigate SC risks. The purpose of this paper is to explore SCRM strategies in Indian automobile industry and to classify automobile firms based on SCRM dimensions.

Design/methodology/approach
– A survey instrument on SCRM dimensions was designed and data were collected from 79 automobile firms. Principle component analysis (PCA) was performed on the collected data to derive the factors underlying SCRM dimensions. Further, cluster analysis using extracted factors as a clustering variate was performed to identify strategic groups from the given set of firms.

Findings
– PCA derived seven factors, namely: avoidance, supplier development, flexibility, risk pooling, redundancy, integration and control strategies. The surveyed firms were classified into two clusters as low and high SCRM level.

Research limitations/implications
– A limitation of this study is that data were collected from a single industry and in a single country.

Practical implications
– Understanding of SCRM dimensions shall increase the use of these dimensions and firms can mitigate negative effects of SC risks. The detailed operationalization of SCRM strategies highlights the importance of three strategies: avoidance, integration and supplier development. Managers’ understanding of SCRM strategies will improve the firm's performance and business excellence.

Originality/value
– This research empirically validates SCRM strategies and investigates how these create differences among firms.
Exploring dimensions of firm competencies and their impact on performance
Authors: Dubey Rameshwar , Singh Tripti , Samar Ali Sadia , Venkatesh V.G. , K. Gupta Omprakash 
Published: September 2014

Purpose
– The purpose of this paper is to explore the dimensions of Indian manufacturing firms’ competencies and to study the impact of these competencies on firm performance.

Design/methodology/approach
– The authors have adopted a literature survey to identify variables and gaps in the research. Based on the construct and its item identified through the literature review the authors have developed a structured questionnaire which was pre-tested before being used for the final survey. The authors have collected data from 100 firms out of 275 targeted firms in two phases which represents a 36.36 per cent response rate. The data have been subjected to exploratory factor analysis (EFA) using varimax rotation, which reduced the data into seven parsimonious and orthogonal factors. The authors then carried out regression analysis using EFA output to test the relationship between six independent variables, representing competencies of the firm and performance.

Findings
– Findings show that EFA has reduced the data into seven factors, out of which six represent firm competencies and one represents firm performance. The competencies which have been identified are supply-demand coordination and product pricing, logistics, marketing, procurement, manufacturing simplicity and product quality and preventive maintenance. The EFA output was further tested using multiple linear regression analysis which shows that out of six competencies, four are positively supporting, except procurement which is negatively supporting and logistics which is found to be statistically insignificant.

Research limitations/implications
– The conclusive model suggests that there is considerable impact from other deterministic variables which are not assumed in the present study, and some of the variance has been accounted for by stochastic variables and response error. However, utmost care has been taken to minimise response error by personal follow-up with each of these firms. The outcome of the quantitative analysis provides an insight into firm competencies and their impact on firm performance. It is very important for the managers who are interested in deriving superior performance from their firm and focusing on supply-demand coordination and product pricing, manufacturing simplicity, marketing and product quality and preventive maintenance practices.

Originality/value
– This original study has been carried out by researchers in India on Indian manufacturing firms and adopted an EFA technique to identify dimensions which are unique in their contribution.
Inter-firm job mobility and occupational transitions in Spain: are they related?
Authors: Caparrós Ruiz Antonio 
Published: September 2014

Purpose– The purpose of this paper is to shed knowledge about the relationship between the inter-firm job mobility and the occupational transitions in Spain during the last years. In particular, it is tested whether if the type of job-to-job mobility (voluntary or involuntary) has some influence on the workers careers. The empirical analysis is based on panel data provided by the Living Condition Survey, which is conducted by the Spanish Statistics Institute (INE). The period analysed covers the years between 2005 and 2010 (both inclusive), what allows observing the labour mobility patterns in the recent Spanish economic crisis.Design/methodology/approach– The econometric specification used to analyse occupational mobility corresponds to a random effect panel multinomial logit model. The econometric model is estimated separately for workers that have remained at the same firm and for workers who have changed firms; for the latter group, a dummy variable indicating whether the individual quit or was laid off is included as a regressor.Findings– The results derived from the estimates of the econometric specifications show that individuals who voluntarily leave a firm find the decision has a positive effect on their careers, as their probability of upward occupational mobility is more than 90 per cent higher than for individuals who leave their previous position as a result of having been laid off.Social implications– This result is an argument in favour of adopting active labour market policies that help improve information flows in the labour market and allow workers a better understanding of potential job offers from outside firms.Originality/value– This paper analyses the relationship between inter-firm mobility and occupational transitions that has not yet addressed in the economic literature for Spain.
The psychological impact of agency worker utilisation
Authors: Toms Simon , Biggs David 
Published: September 2014

Purpose– Agency work represents a unique form of employment that has received increased attention in recent years. Supporters of the agency employment industry have cited increased accessibility and flexibility at an individual and organisational level, yet critics have highlighted disparities in treatment and the limited protection afforded by the contract. Previous psychological studies into the working experiences of these employees have forwarded a series of findings that have frequently conflicted, so this paper begins by exploring research into the areas of motive, job satisfaction, job security, and organisational support. The purpose of this paper is to better understand how this form of employment can psychologically affect agency workers by focusing upon these key areas.Design/methodology/approach– The study's research design incorporated 25 semi-structured interviews with agency workers, recruitment consultants, and representatives from third-party employers. These interviews were then supplemented by longitudinal data from follow-up interviews conducted with agency workers from the initial sample. During the study, the researcher undertook a number of agency working assignments, and ethnographic analysis of diary extracts represented a third source of data.Findings– Results highlighted the importance of motive, as it was found to influence how agency workers viewed their employment. The lack of obligation in temporary contracts was perceived to lead to isolation from permanent colleagues, increase vulnerability, and reduce job security and organisational commitment.Research limitations/implications– Findings strongly supported the claim that the pre-assignment motives of individuals had a significant impact upon their resulting experiences. Agency workers employed in longer-term assignments reported greater integration into the organisation, resulting in increased commitment towards the third-party employer, and improved relationships with permanent staff.Originality/value– The current research incorporated multiple perspectives to create an increased understanding of the agency employment industry and its impact upon individuals.
