An evolutionary model for the gamma-ray system PSR J1311−3430 and its companion
Authors: Benvenuto O. G. , De Vito M. A. , Horvath J. E. 
Published: May 2013

Abstract
The most recent member of the millisecond pulsar with very low mass companions and short orbital periods class, PSR J1311−3430 (Pletsch et al. 2012) is a remarkable object in various senses. Besides being the first discovered in gamma rays, its measured features include the very low or absent hydrogen content. We show in this Letter that this important piece of information leads to a very restricted range of initial periods for a given donor mass. For that purpose, we calculate in detail the evolution of the binary system self-consistently, including mass transfer and evaporation, finding the features of the new evolutionary path leading to the observed configuration. It is also important to remark that the detailed evolutionary history of the system naturally leads to a high final pulsar mass, as it seems to be demanded by observations.

AbstractSpectropolarimetry provides the means to probe the 3D geometries of supernovae (SNe) at early times. We report spectropolarimetric observations of the Type Ia SN 2012fr at four epochs: −11, −5, +2 and +24 d, with respect to B-light-curve maximum. SN 2012fr is a normal Type Ia SN, similar to SNe 1990N, 2000cx and 2005hj (that all exhibit low velocity decline rates for the principal Si ii line). The SN displays high-velocity components at −11 d that are highly polarized. The polarization of these features decreases as they become weaker from −5 d. At +2 d, the polarization angles of the low-velocity components of silicon and calcium are identical and oriented at 90° relative to the high-velocity Ca component. In addition to having very different velocities, the high- and low-velocity Ca components have orthogonal distributions in the plane of the sky. The continuum polarization for the SN at all four epochs is low, &lt;0.1 per cent. We conclude that the low level of continuum polarization is inconsistent with the merger-induced explosion scenario. The simple axial symmetry evident from the polarization angles of the high-velocity and low-velocity Ca components, along with the presence of high-velocity components of Si and Ca, is perhaps more consistent with the pulsating delayed detonation model. We predict that, during the nebular phase, SN 2012fr will display blueshifted emission lines of Fe-group elements.
The S2 star as a probe of the accretion disc of Sgr A*
Authors: Giannios Dimitrios , Sironi Lorenzo 
Published: May 2013

Abstract
How accretion proceeds around the massive black hole in the Galactic Centre and other highly sub-Eddington accretors remains poorly understood. The orbit of the S2 star in the Galactic Centre passes through the accretion disc of the massive black hole and any observational signature from such interaction may be used as an accretion probe. Because of its early stellar type, S2 is expected to posses a fairly powerful wind. We show here that the ram pressure of the accretion disc shocks the stellar wind fairly close to the star. The shocked fluid reaches a temperature of ∼1 keV and cools efficiently through optically thin, thermal bremsstrahlung emission. The radiation from the shocked wind peaks around the epoch of the pericentre passage of the star at a luminosity potentially comparable to the quiescent emission detected from Sgr A*. Detection of shocked wind radiation can constrain the density of the accretion disc at a distance of several thousands of gravitational radii from the black hole.

Abstract
We study the interplay between gas phase metallicity (Z), specific star formation rate (SSFR) and neutral hydrogen gas (H i) for galaxies of different stellar masses. Our study uses spectroscopic data from Galaxy and Mass Assembly and Sloan Digital Sky Survey (SDSS) star-forming galaxies, as well as H i detection from the Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) and Galex Arecibo SDSS Survey (GASS) public catalogues. We present a model based on the Z–SSFR relation that shows that at a given stellar mass, depending on the amount of gas, galaxies will follow opposite behaviours. Low-mass galaxies with a large amount of gas will show high SSFR and low metallicities, while low-mass galaxies with small amounts of gas will show lower SSFR and high metallicities. In contrast, massive galaxies with a large amount of gas will show moderate SSFR and high metallicities, while massive galaxies with small amounts of gas will show low SSFR and low metallicities. Using ALFALFA and GASS counterparts, we find that the amount of gas is related to those drastic differences in Z and SSFR for galaxies of a similar stellar mass.

Published: May 2013

AbstractJasmonates (JAs) are plant hormones that regulate the balance between plant growth and responses to biotic and abiotic stresses. Although recent studies have uncovered the mechanisms for JA-induced responses in Arabidopsis thaliana, the mechanisms by which plants attenuate the JA-induced responses remain elusive. Here, we report that a basic helix-loop-helix–type transcription factor, ABA-INDUCIBLE BHLH-TYPE TRANSCRIPTION FACTOR/JA-ASSOCIATED MYC2-LIKE1 (JAM1), acts as a transcriptional repressor and negatively regulates JA signaling. Gain-of-function transgenic plants expressing the chimeric repressor for JAM1 exhibited substantial reduction of JA responses, including JA-induced inhibition of root growth, accumulation of anthocyanin, and male fertility. These plants were also compromised in resistance to attack by the insect herbivore Spodoptera exigua. Conversely, jam1 loss-of-function mutants showed enhanced JA responsiveness, including increased resistance to insect attack. JAM1 and MYC2 competitively bind to the target sequence of MYC2, which likely provides the mechanism for negative regulation of JA signaling and suppression of MYC2 functions by JAM1. These results indicate that JAM1 negatively regulates JA signaling, thereby playing a pivotal role in fine-tuning of JA-mediated stress responses and plant growth.
Reversible high-temperature phase transition of a manganese(II) formate framework with imidazolium cations
Authors: Wang Bi-Qin , Yan Hai-Biao , Huang Zheng-Qing , Zhang Zhi 
Published: May 2013

A new metal–formate framework, poly[1H-imidazol-3-ium [tri-μ2-formato-manganese(II)]], {(C3H5N2)[Mn(HCOO)3]}n, was synthesized and its structural phase transition was studied by thermal analysis and variable-temperature X-ray diffraction analysis. The transition temperature is around 435 K. The high-temperature phase is tetragonal and the low-temperature phase is monoclinic, with a β angle close to 90°. The relationship of the unit cells between the two phases can be described as:aHT= 0.5aLT+ 0.5bLT;bHT= −0.5aLT+ 0.5bLT;cHT = 0.5cLT. In the high-temperature phase, both the framework and the guest 1H-imidazol-3-ium (HIm) cations are disordered; the HIm cations are located about 2mmsites and were modelled as fourfold disordered. The Mn and a formate C atom are located on fourfold rotary inversion axes, while another formate C atom is on a mirror plane. The low-temperature structure is ordered and consists of two crystallographically independent HIm cations and two crystallographically independent Mn2+ions. The phase transition is attributable to the order–disorder transition of the HIm cations.
Physician directed information prescription service (IPs): barriers and drivers
Authors: Zarea Gavgani Vahideh , Roshani Shiramin Ali 
Published: May 2013

PurposeThe objective of this study is to find out physicians' attitudes towards prescribing information to patients and the barriers they may face regarding IPs to patients.Design/methodology/approachA cross‐sectional survey of 176 physicians working as clinical faculty members of the Tabriz University of Medical Sciences about the information prescription service (IPs) was undertaken using a structured and validated questionnaire. Descriptive statistics and a Fisher's exact test or chi square test were used to analyze data. A P value less than 0.05 was considered significant. All data were analyzed using SPSS.17.0.FindingsThe study found that physicians are positive about providing IPs. Most of the specialists, i.e. 95.4 per cent (n=167) completely agreed with prescribing information to patients. The physicians rated barriers that they may face in offering IPs. Majority of the specialists 97 per cent (n=174) acknowledged that patients have the right to receive IPs while being seen by healthcare providers. The study did not find significant association between specialty of physicians with their opinion about importance and necessity of IPs. However, there is a statistically significant relationship between the physicians' specialty and their opinions about the following ideas: “information may create side effects” (p=0.01), “the stage of diseases that patient experiences is important and to be considered in personalization of IPs” (p=0.01).Originality/valueThis study is unique because there are no similar studies in the published literature. Physicians are one of the main stakeholders in IPs, therefore it is important to find out their opinions and attitudes towards prescription of information.
Enabler and inhibitor factors influencing competitive intelligence practices
Authors: Garcia‐Alsina Montserrat , Ortoll Eva , Cobarsí‐Morales Josep 
Published: May 2013

PurposeThis paper has a twofold aim. Firstly, to give some insight into competitive intelligence practices in a little‐explored area in the field of competitive intelligence: the higher education sector. Secondly, to find out more about the factors influencing competitive intelligence practices, since little research on this subject has been published.Design/methodology/approachThe investigation used a mixed‐methods approach, including face‐to‐face, semi structured interviews with 47 university managers (degree coordinators, deans and vice‐rectors), followed by a semi‐structured questionnaire carried out with 400 degree coordinators and deans and analysed quantitatively and qualitatively. The interviews informed the questionnaire design.FindingsThe survey confirms the proposed framework's usefulness for analysing the enabler and inhibitor factors in an organisation for promoting efficient competitive intelligence practice and also gives some insight into which factors enable or inhibit the efficacy of competitive intelligence practices in Spanish universities.Research limitations/implicationsThe research focused on degree design adapted to the EHEA. A larger study designed to focus on other management areas in universities would provide a fuller picture of factors influencing competitive intelligence practices.Practical implicationsThe findings indicate the areas where universities could plan actions to optimise intelligence activities, make the most of them and stand out from the rest.Originality/valueThis paper sets out a framework to describe factors related to intelligence function and cycle. In addition, the study reveals which indicators act as enablers or inhibitors for competitive intelligence practices and takes account of some of the particular features of the higher education sector.

Authors: Kılınççeker Güray , Demir Hasan 
Published: May 2013

PurposeThe purpose of this paper is to investigate the inhibition effect of cysteine on the corrosion behaviour of copper in 3.5% NaCl solution with and without cysteine.Design/methodology/approachFor this purpose, potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS) techniques were used. The surface morphology of the metal sample after exposure to the corrosive medium was investigated by scanning electron microscopy (SEM). The effect of temperature also was studied over the range 298‐328 K. Thermodynamic parameters (ΔG, ΔH and ΔS) were calculated and discussed.FindingsIt was found that cysteine could inhibit the corrosion of copper in 3.5% NaCl solution. Cysteine is an organic corrosion inhibitor for copper, and its molecules are physically adsorbed to form a protective film. Inhibition efficiency increases with decreasing cysteine concentration and the product behaves as an anodic‐type inhibitor.Research limitations/implicationsIn this study, the inhibitory effect of cysteine with temperature change was investigated in environments containing 10−2 M cysteine solution at pH 8.5.Practical implicationsIt will be possible to replace other inhibitors, with cysteine for copper protection in heating/cooling systems at higher temperatures.Originality/valueCysteine acts as an anodic inhibitor especially for copper‐based materials in acidic solution. The interaction between the cysteine molecule and copper in alkaline media has not been investigated in detail. The main objectives of this study was to gain some insight into the protection of copper by cysteine in 3.5% NaCl medium at a pH value of 8.5.

Published: May 2013

PurposeThis paper aims to develop a theoretical base for supply chain quality from the learning perspective. Through utilizing the relational view of inter‐organizational competitive advantage, the paper identifies learning‐driven practices that influence buyer‐supplier performance outcomes.Design/methodology/approachA review of the literature in quality management, supply chain management and strategic management is conducted to develop key practices associated with quality management in a supply chain environment.FindingsThe findings suggest that quality management facilitates cooperative learning and improves inter‐organizational learning processes. At the supply chain level, it enhances supply chain satisfaction and supply chain performance.Originality/valueThe study contributes to our understanding of quality management practices within a supply chain environment from an inter‐organizational learning perspective. It extends the concept of quality to the supply chain through focusing on key practices that influence the quality of supply chain relationships.
A library in the palm of your hand
Authors: Lee Ballard Terry , Blaine Anna 
Published: May 2013

PurposeIn response to the changing world of information access, librarians at the New York Law School's Mendik Library became interested in providing a full‐service mobile phone application so that users could search the catalog, access the reserves module, renew books and find information such as library hours. The purpose of this paper is to show how the library went from this concept to an award‐winning product.Design/methodology/approachThe paper shows step by step how the librarians listened to experts in the field, searched the mobile stores to find other libraries that have done this, chosen a vendor, and rolled out the service with a multimedia information campaign.FindingsUsing a team approach, it is possible to develop a mobile application that is useful and still being accessed a year after its first launch.Research limitations/implicationsMore needs to be done to see the precise state of mobile access in the world's libraries.Originality/valueThe approach documented in the paper will serve as a template for libraries planning to add mobile access, but are unsure of how to proceed.
Applying the free market philosophy to healthcare
Authors: Testa Pat , Block Walter E. 
Published: May 2013

PurposeThe purpose of this paper is to support the claim that socialism is ineffective and inefficient, and that this insight applies to socialized medicine, as well as all other forms of socialism.Design/methodology/approachThe main method utilized in this paper is the application of basic supply and demand analysis, based on private property rights and profit considerations, to healthcare.FindingsIt is found that the application of these basic elements of economics to healthcare demonstrates that free enterprise can better attain the ends of healthcare than can socialism.Research limitations/implicationsFuture research should focus on the anomaly that most people view socialism with great disdain, but not when it comes to health care. Why the logical disconnect?Practical implicationsThe Soviet Union went through economic paroxysms in ridding itself of socialism. If the implications of this research are implemented, these can be avoided in our health care system.Social implicationsThe impact on society of this research will be very beneficial; under free enterprise, costs will be lower, and quality of care higher. But public attitudes are at present very much in favor of socialized medicine. Hopefully, one of the benefits of the present paper will be to change this.Originality/valueThe value of the paper is that, in some small way, it will help attain greater health for the entire population.
The impact of reward personalisation on frequent flyer programmes
'
perceived value and loyalty
Authors: Meyer-Waarden Lars 
Published: May 2013

Purpose
– The purpose of this research is to contribute to a better theoretical and empirical knowledge about the way frequent flyer programmes influence customer behaviour. It aims to describe the relationships between purchase orientations and personalized rewards on customers
'
perceived programme value and subsequent loyalty.

Design/methodology/approach
– The research uses self-determination theory (SDT) and purchase orientations to classify types of rewards in terms of their effect on perceived programme value and loyalty. Scales are developed through exploratory and confirmatory factor analysis. To validate the hypotheses, surveys are realized in a major international airline. Structural equation modelling confirms the research model.

Findings
– Perceived value and loyalty vary according to purchase orientation, in support of the SDT. Intrinsic (extrinsic) rewards motivate customers to act to obtain a benefit within (apart from) the target of their purchase orientation and influences loyalty positively (have low impact on loyalty).

Research limitations/implications
– Further testing of reward types, in(ex)trinsic motivation, SDT, across multiple contexts is necessary for validity enhancement.

Practical implications
– Differentiation through tailored (non-)monetary rewards is possible in markets marked by strong competition to appeal to different segments.

Originality/value
– This is one of the pioneer articles in the use of SDT in marketing research. The development of scales which focus on reward types and the moderating impact of purchase orientations on frequent flyer programmes
'
perceived value and loyalty is another contribution.
Developing an integrated vision of customer value
Authors: Martelo Landroguez Silvia , Barroso Castro Carmen , Cepeda-Carrión Gabriel 
Published: May 2013

Purpose
– The aim of this paper is to contribute to the service management literature by identifying the possible relationship between customer value seen from the customer perspective and from the firm perspective, and its potential influence on the value created for the service customer. The authors have not found any papers which focus on the relationship between these different perspectives of customer value, and the aim is to fill this gap in the literature.

Design/methodology/approach
– The paper proposes that a relationship between the different perspectives exists and attempts to create an integrated vision of customer value.

Findings
– The proposed model shows that it is the relationship between customer value from the customer
'
s point of view and customer value from the firm
'
s point of view that really creates value.

Practical implications
– The paper can influence the current service management of firms with regard to customer value creation in several ways.

Originality/value
– From the existing literature, it is deduced that customer value can be seen as perceived value (the customer perspective) or as value creation and appropriation (the firm perspective). The paper proposes that these three types of value are equivalent in an important level and should always be interrelated.

Predictors of retention in “transitional” rehabilitation: dynamic versus static client variables
Authors: Gholab Karis M. , Magor‐Blatch Lynne E. 
Published: May 2013

PurposeProblematic substance use is associated with adverse outcomes that extend beyond the individual, resulting in significant cost to the community through health care, criminal justice and other psychosocial factors, including child protection and family support. These factors create concerns for treatment services, with an increasing demand for cost‐effective solutions to this problem. This paper seeks to address these issues.Design/methodology/approachThis prospective cohort study examined the effect of client variables on retention within a short‐term (56 days) modified therapeutic community (MTC) in the Australian Capital Territory. A total of 28 residents (17 males, 11 females) took part in the study, which included quantitative and qualitative measures.FindingsResults demonstrate a trend in favour of dynamic client variables as effective predictors of retention, with substance use severity being a significant predictor (p=0.023, d=0.91). Content analysis demonstrates that those with severe substance use have more intentions to engage in aftercare.Originality/valueShort term treatments are seen as providing a gateway to further treatment, especially for chronic substance‐using clients.
