Authors: Zhu Qin-tian , Li Jing , Shi Cheng-bin , Yu Wen-tao , Shi Chang-min , Li Ji-hui
Published: November 2016

A fundamental study on the precipitation behavior of carbides was carried out. Thermo-calc software, scanning electron microscopy, electron probe microanalysis, transmission electron microscopy, X-ray diffractometry and high-temperature confocal laser scanning microscopy were used to study the precipitation and transformation behaviors of carbides. Carbide precipitation was of a specific order. Primary carbides (M7C3) tended to be generated from liquid steel when the solid fraction reached 84 mol.%. Secondary carbides (M7C3) precipitated from austenite and can hardly transformed into M23C6 carbides with decreasing temperature in air. Primary carbides hardly changed once they were generated, whereas secondary carbides were sensitive to heat treatment and thermal deformation. Carbide precipitation had a certain effect on steel-matrix phase transitions. The segregation ability of carbon in liquid steel was 4.6 times greater that of chromium. A new method for controlling primary carbides is proposed.

Published: November 2016

Graphene oxide (GO) is an oxidized derivative of graphene used in biotechnology and medicine. The safety of GO is uncertain, so we evaluated its toxicity in male rats. Rat tail veins were injected with 2.5, 5, or 10 mg/kg GO for seven days and behavioral patterns, pathology, and tissue morphology were assessed. Data show that behaviors were not altered according to an open field test and a functional observational battery test, but histopathological analysis indicated that GO caused inflammation of the lung, liver, and spleen. GO also reduced cholesterol, high density lipoprotein (HDL), and low density lipoprotein (LDL). No other organs were modified. Thus, high concentrations of GO are toxic for the lung, liver, and spleen, but the mechanism by which this occurs requires more study.
Putting the Barker Theory into the Future: Time to Act on Preventing Pediatric Obesity

Published: November 2016

Growth and development are key characteristics of childhood and sensitive markers of health and adequate nutrition. The first 1000 days of life—conception through 24 months of age—represent a fundamental period for development and thus the prevention of childhood obesity and its adverse consequences is mandatory. There are many growth drivers during this complex phase of life, such as nutrition, genetic and epigenetic factors, and hormonal regulation. The challenge thus involves maximizing the potential for normal growth without increasing the risk of associated disorders. The Mediterranean Nutrition Group (MeNu Group), a group of researchers of the Mediterranean Region, in this Special Issue titled “Prevent Obesity in the First 1000 Days”, presented results that advanced the science of obesity risk factors in early life, coming both from animal model studies and studies in humans. In the future, early-life intervention designs for the prevention of pediatric obesity will need to look at different strategies, and the MeNu Group is available for guidance regarding an appropriate conceptual framework to accomplish either prevention or treatment strategies to tackle pediatric obesity.
Metabolomics, a Powerful Tool for Agricultural Research
Authors: Tian He , Lam Sin , Shui Guanghou
Published: November 2016

Metabolomics, which is based mainly on nuclear magnetic resonance (NMR), gas-chromatography (GC) or liquid-chromatography (LC) coupled to mass spectrometry (MS) analytical technologies to systematically acquire the qualitative and quantitative information of low-molecular-mass endogenous metabolites, provides a direct snapshot of the physiological condition in biological samples. As complements to transcriptomics and proteomics, it has played pivotal roles in agricultural and food science research. In this review, we discuss the capacities of NMR, GC/LC-MS in the acquisition of plant metabolome, and address the potential promise and diverse applications of metabolomics, particularly lipidomics, to investigate the responses of Arabidopsis thaliana, a primary plant model for agricultural research, to environmental stressors including heat, freezing, drought, and salinity.
In Situ Studies and Magnetic Properties of the Cmcm Polymorph of LiCoPO4 with a Hierarchical Dumbbell-Like Morphology Synthesized by Easy Single-Step Polyol Synthesis
Authors: Alarcón-Suesca Carlos , Ludwig Jennifer , Hlukhyy Viktor , Stinner Christoph , Nilges Tom
Published: November 2016

LiCoPO4 (LCP) exists in three different structural modifications: LCP-Pnma (olivine structure), LCP-Pn21a (KNiPO4 structure type), and LCP-Cmcm (Na2CrO4 structure type). The synthesis of the LCP-Cmcm polymorph has been reported via high pressure/temperature solid-state methods and by microwave-assisted solvothermal synthesis. Phase transitions from both LCP-Pn21a and LCP-Cmcm to LCP-Pnma upon heating indicates a metastable behavior. However, a precise study of the structural changes during the heating process and the magnetic properties of LCP-Cmcm are hitherto unknown. Herein, we present the synthesis and characterization of LCP-Cmcm via a rapid and facile soft-chemistry approach using two different kinetically controlled pathways, solvothermal and polyol syntheses, both of which only require relatively low temperatures (~200 °C). Additionally, by polyol, method a dumbbell-like morphology is obtained without the use of any additional surfactant or template. A temperature-dependent in situ powder XRD shows a transition from LCP-Cmcm at room temperature to LCP-Pnma and finally to LCP-Pn21a at 575 and 725 °C, respectively. In addition to that, the determination of the magnetic susceptibility as a function of temperature indicates a long-range antiferromagnetic order below TN = 11 K at 10 kOe and 9.1 K at 25 kOe. The magnetization curves suggests the presence of a metamagnetic transition.
Tribological Stress of Lubricating Greases in the Light of System Entropy
Authors: Kuhn Erik
Published: November 2016

Lubricating greases show a structural degradation due to friction stress. The shear process dissipates energy. This results in a breakdown of the thickener structure, heat and entropy generation. Tribo-systems are energy driven systems. The stressed lubricating grease is modeled as a subsystem and presents an open thermodynamic system. Investigations were made to obtain more information about the correlation of system entropy and structural degradation of a lubricating grease. Experimental studies were done to estimate the role in terms of entropy transport for the open system. The degradation-entropy theorem was applied with the help of an empirical model to describe the correlation between degradation process and entropy production for the special case of a closed and stationary system.
A Stereocontrolled Protocol to Highly Functionalized Fluorinated Scaffolds through a Fluoride Opening of Oxiranes
Authors: Remete Attila , Nonn Melinda , Fustero Santos , Fülöp Ferenc , Kiss Loránd
Published: November 2016

A novel selective and substrate-dependent synthetic protocol has been developed towards the synthesis of various fluorine-containing, highly functionalized cycloalkane derivatives. The method involves the stereoselective epoxidation of some unsaturated cyclic β-amino acid derivatives as model compounds, followed by a regioselective fluoride opening of oxiranes under various conditions with Deoxofluor and XtalFluor-E reagents, thereby offering an insight into this new epoxide opening methodology with fluoride.

Authors: Park Hee-Soo , Oh Sang-Hun , Kim Hye-Shin , Choi Dong-Rack , Kwak Jin-Hwan
Published: November 2016

Zabofloxacin is a novel fluoroquinolone agent that has potent activity against gram-positive pathogens. In this study, we confirmed that zabofloxacin showed the most potent in vitro and in vivo activities against drug-resistant Streptococcus pneumoniae. Among the fluoroquinolone compounds, zabofloxacin showed the most potent in vitro activity against clinical isolates of penicillin-sensitive S. pneumoniae (minimum inhibitory concentration, MIC90: 0.03 mg/L) and penicillin-resistant S. pneumoniae (MIC90: 0.03 mg/L). Against quinolone-resistant S. pneumoniae, zabofloxacin (MIC90: 1 mg/L) was more active than ciprofloxacin, sparfloxacin, and moxifloxacin; however, its activity was the same as that of gemifloxacin. The in vivo activity of zabofloxacin was most potent among the quinolone compounds tested against the systemic infection and respiratory tract infection models in mice.
Quantitative Structure Activity Relationship of Cinnamaldehyde Compounds against Wood-Decaying Fungi
Authors: Yang Dongmei , Wang Hui , Yuan Haijian , Li Shujun
Published: November 2016

Cinnamaldehyde, of the genius Cinnamomum, is a major constituent of the bark of the cinnamon tree and possesses broad-spectrum antimicrobial activity. In this study, we used best multiple linear regression (BMLR) to develop quantitative structure activity relationship (QSAR) models for cinnamaldehyde derivatives against wood-decaying fungi Trametes versicolor and Gloeophyllun trabeum. Based on the two optimal QSAR models, we then designed and synthesized two novel cinnamaldehyde compounds. The QSAR models exhibited good correlation coefficients: R2Tv = 0.910 for Trametes versicolor and R2Gt = 0.926 for Gloeophyllun trabeum. Small errors between the experimental and calculated values of two designed compounds indicated that these two QSAR models have strong predictability and stability.
Medication Safety: Experiential Learning for Pharmacy Students and Staff in a Hospital Setting
Authors: Graudins Linda , Dooley Michael
Published: November 2016

Medication Safety has been an established pharmacy specialty in Australian hospitals since the early 2000s and is now one of the ten Australian hospital accreditation standards. Although advances have occurred, medication-related patient harm has not been eradicated. Victorian undergraduate pharmacy programs include some aspects of medication safety, however clinical pharmacy experience, along with interpersonal and project management skills, are required to prepare pharmacists to be confident medication safety practitioners. This article outlines the range of medication safety-related training offered at an Australian tertiary teaching hospital, including; on-site tutorial for undergraduate students, experiential placement for pharmacy interns, orientation for pharmacy staff and resources for credentialing pharmacists for extended roles. Improvements continue to be made, such as electronic medication management systems, which increase the safe use of medications and facilitate patient care. Implementation and evaluation of these systems require medication safety expertise. Patients’ engaging in their own care is an acknowledged safety improvement strategy and is enhanced by pharmacist facilitation. Building educator skills and integrating experiential teaching with university curricula should ensure pharmacists have both the knowledge and experience early in their careers, in order to have a leading role in future medication management.
Segmentation by Tourist Expenditure Composition: An Approach with Compositional Data Analysis and Latent Classes
Authors: Ferrer-Rosell Berta , Coenders Germà , Martínez-Garcia Esther
Published: November 2016

In this article, we propose segmenting tourists according to trip budget share (in other words, the proportions of total expenditure devoted to different items, such as transportation, accommodation, and activities undertaken). We put forward a method involving a combination of compositional
data analysis (CODA) and mixture models (latent class models), which, by contrast with traditional methods (e.g., cluster analysis), makes it possible to carry out statistical inference with regard to segment characteristics and their relationships with external variables, such as tourist
background. The way we use the CODA methodology is intuitively appealing and boils down to building transformed variables that can be tailored to the specific research questions. We analyze the spending profiles of tourists arriving in Spain on low-cost carriers, with relevant and interpretable
results.
Practical Sales Forecasting: Potential Solutions for Independently Owned Hotels
Authors: Sorokina Ekaterina , Semrad Kelly , Mills Brian
Published: November 2016

In 2013, 80% of the total hotel closures in the US were independently owned hotel properties. The impact of external factors coupled with the inability of independently owned properties to adapt quickly to a complex operating environment results in high uncertainty of future operations and reduced competitiveness. However, the preservation of this sector is a necessary condition for the lodging industry given that 49% of the worldwide room supply is independently owned and managed. Therefore, the primary objectives of this research study are to increase awareness and the need for research regarding the importance of the independently owned hotel sector and to provide managers of these properties with forecasting tools that may enhance hotels' competitiveness. The operational challenges of independently hotels are unique as well as their needs. Accordingly, potential challenges of these properties are reviewed to stress the need for forecasting and to determine tools that are reliable and at the same time account for the challenges unique to independent hotels. The comparison of strengths and weaknesses of commonly used forecasting tools shows that time series models may be both reliable and practical for the managers of independently owned hotels to use.
Detecting Latent Classes in Tourism Data Through Response-Based Unit Segmentation (REBUS) in Pls-Sem
Authors: Assaker Guy , Hallak Rob
Published: November 2016

This research note describes Response-Based Unit Segmentation (REBUS), a “latent class detection” technique used in partial least squares–structural equation modeling (PLS-SEM) to examine data heterogeneity. The research note is presented in two parts: Part A presents
an overview of REBUS, including its development, algorithm, and its primary functions. Part B demonstrates the application of REBUS in examining a validated tourism model of destination image, satisfaction, and destination loyalty. The example shows how REBUS is used to examine variances in
a structural equation model, to detect “classes,” and to profile and understand the heterogeneous groups in an SEM context. REBUS is powerful in uncovering variances and possible moderators in structural models, especially when the data are cross-sectional, heterogeneous, and multivariate
nonnormal. Finally, the research note demonstrates how REBUS detects classes in models with higher order (multidimensional) constructs, which are often the case in tourism research.
Morphology of SiO2 films as a key factor in alignment of liquid crystals with negative dielectric anisotropy
Authors: Tkachenko Volodymyr , Marino Antigone , Otón Eva , Bennis Noureddine , Otón Josè Manuel
Published: November 2016

Control of liquid crystal (LC) orientation using a proper SiO2 alignment layer is essential for the optimization of vertically aligned nematic (VAN) displays. With this aim, we studied the optical anisotropy of thin SiO2 films by generalized ellipsometry as a function of deposition angle. The columnar SiO2 structure orientation measured by a noninvasive ellipsometry technique is reported for the first time, and its morphology influence on the LC alignment is demonstrated for large deposition angles.
Focus association into copies and the scope of even
Authors: Erlewine Michael Yoshitaka
Published: November 2016

Nakanishi 2012 presents a novel argument for the so-called “scope theory” of English VP-even, based on examples with antecedent-contained deletion (ACD). Nakanishi’s argument is based on the assumption that even cannot associate with a focus which has moved out of its scope. I show that this assumption is incorrect, defusing Nakanishi’s argument. I propose that when even associates with a focus which has moved out of its scope, it actually associates with focused material in the lower copies of movement (trace positions). I show that a closer look at ACD examples of Nakanishi’s type in fact forms a new argument against the scope theory. I conclude that English VP-even must always be interpreted in its pronounced position. The patterns of focus association with even presented here constitute a new argument for the copy theory of movement.
GROWTH OF A GAS BUBBLE IN A STEADY DIFFUSION FIELD IN A TISSUE UNDERGOING DECOMPRESSION
Authors: Mohammadein Selim A. , Mohamed Khaled G.
Published: November 2016

This paper presents parameterized study on the growth of a convective gas bubble in tissues of a steady diffusion field. Resulting formulae are obtained analytically, which are valid for constant ambient pressure. It’s found that the growing bubble radius is proportional to initial bubble radius, initial concentration difference, diver’s average temperature and initial void fraction which is the dominant parameter, while it’s inversely proportional to surface tension, viscosity, density ratio and ambient pressure. Comparison to some previous work is performed.
AN EXTENSION OF THE PRODUCT INTEGRATION METHOD TO L1 WITH APPLICATIONS IN ASTROPHYSICS
Authors: Grammont Laurence , Ahues Mario , Kaboul Hanane
Published: November 2016

A Fredholm integral equation of the second kind in L1([a, b], C) with a weakly singular kernel is considered. Sufficient conditions are given for the existence and uniqueness of the solution. We adapt the product integration method proposed in C0 ([a, b], C) to apply it in L1 ([a, b], C), and discretize the equation. To improve the accuracy of the approximate solution, we use different iterative refinement schemes which we compare one to each other. Numerical evidence is given with an application in Astrophysics.

We present a robust measurement of the rest-frame UV luminosity function (LF) and its evolution during the peak epoch of cosmic star formation at

We use our deep near-ultraviolet imaging from WFC3/UVIS on the Hubble Space Telescope and existing Advanced Camera for Surveys (ACS)/WFC and WFC3/IR imaging of three lensing galaxy clusters, Abell 2744 and MACS J0717 from the Hubble Frontier Field survey and Abell 1689. Combining deep UV imaging and high magnification from strong gravitational lensing, we use photometric redshifts to identify 780 ultra-faint galaxies with

AB mag at

We run a Monte Carlo simulation to estimate the completeness correction and effective volume for each cluster using the latest published lensing models.

Because the sample sizes are so large and extend to such faint luminosities, the statistical uncertainties are quite small, and systematic uncertainties (due to the assumed size distribution, for example) likely dominate. If we restrict our analysis to galaxies and volumes above

PROPINQUITY OF CURRENT AND VORTEX STRUCTURES: EFFECTS ON COLLISIONLESS PLASMA HEATING
Authors: Parashar Tulasi N , Matthaeus William H
Published: November 2016

Intermittency of heating in weakly collisional plasma turbulence is an active subject of research, with significant potential impact on understanding of the solar wind, solar corona, and astrophysical plasmas. Recent studies suggest a role of vorticity in plasma heating. In magnetohydrodynamics small-scale vorticity is generated near current sheets and this effect persists in kinetic plasma, as demonstrated here with hybrid and fully kinetic particle-in-cell simulations. Furthermore, vorticity enhances local kinetic effects, with a generalized resonance condition selecting sign-dependent enhancements or reductions of proton heating and thermal anisotropy. In such plasmas heating is correlated with vorticity and current density, but more strongly with vorticity. These results help explain several prior results that find kinetic effects and energization near to, but not centered on, current sheets. Evidently intermittency in kinetic plasma involves multiple physical quantities, and the associated coherent structures and nonthermal effects are closely related.
PHOTOMETRIC MONITORING OF THE COLDEST KNOWN BROWN DWARF WITH THE SPITZER SPACE TELESCOPE*

Published: November 2016

Because WISE J085510.83−071442.5 (hereafter WISE 0855-0714) is the coldest known brown dwarf (∼250 K) and one of the Sun’s closest neighbors (2.2 pc), it offers a unique opportunity to study a planet-like atmosphere in an unexplored regime of temperature. To detect and characterize inhomogeneities in its atmosphere (e.g., patchy clouds, hot spots), we have performed time-series photometric monitoring of WISE 0855-0714 at 3.6 and 4.5 μm with the Spitzer Space Telescope during two 23 hr periods that were separated by several months. For both bands, we have detected variability with peak-to-peak amplitudes of 4%–5% and 3%–4% in the first and second epochs, respectively. The light curves are semiperiodic in the first epoch for both bands, but they are more irregular in the second epoch. Models of patchy clouds have predicted a large increase in mid-infrared (mid-IR) variability amplitudes (for a given cloud covering fraction) with the appearance of water ice clouds at T
eff < 375 K, so if such clouds are responsible for the variability of WISE 0855-0714, then its small amplitudes of variability indicate a very small deviation in cloud coverage between hemispheres. Alternatively, the similarity in mid-IR variability amplitudes between WISE 0855-0714 and somewhat warmer T and Y dwarfs may suggest that they share a common origin for their variability (i.e., not water clouds). In addition to our variability data, we have examined other constraints on the presence of water ice clouds in the atmosphere of WISE 0855-0714, including the recent mid-IR spectrum from Skemer et al. (2016). We find that robust evidence of such clouds is not yet available.
CONSTRAINING THE SOLAR CORONAL MAGNETIC FIELD STRENGTH USING SPLIT-BAND TYPE II RADIO BURST OBSERVATIONS
Authors: Kishore P. , Ramesh R. , Hariharan K. , Kathiravan C. , Gopalswamy N.
Published: November 2016

We report on low-frequency radio (85–35 MHz) spectral observations of four different type II radio bursts, which exhibited fundamental-harmonic emission and split-band structure. Each of the bursts was found to be closely associated with a whitelight coronal mass ejection (CME) close to the Sun. We estimated the coronal magnetic field strength from the split-band characteristics of the bursts, by assuming a model for the coronal electron density distribution. The choice of the model was constrained, based on the following criteria: (1) when the radio burst is observed simultaneously in the upper and lower bands of the fundamental component, the location of the plasma level corresponding to the frequency of the burst in the lower band should be consistent with the deprojected location of the leading edge (LE) of the associated CME; (2) the drift speed of the type II bursts derived from such a model should agree closely with the deprojected speed of the LE of the corresponding CMEs. With the above conditions, we find that: (1) the estimated field strengths are unique to each type II burst, and (2) the radial variation of the field strength in the different events indicate a pattern. It is steepest for the case where the heliocentric distance range over which the associated burst is observed is closest to the Sun, and vice versa.
EXPLORING THE TRANSIENT RADIO SKY WITH VLITE: EARLY RESULTS

Published: November 2016

We report on a search for radio transients at 340 MHz with the Jansky Very Large Array Low-band Ionosphere and Transient Experiment (VLITE). Between 2015 July 29 and September 27, operating in commensal mode, VLITE imaged approximately 2800 pointings covering 12,000 deg2 on the sky, sampling timescales ranging from tens of seconds to several hours on a daily basis. In addition, between 2015 February 25 and May 9, VLITE observed 55 epochs of roughly 2–4 hr each toward the COSMOS field. Using existing radio source catalogs, we have searched all of the daily VLITE images for transients, while for the COSMOS field we compared individual images and the summed image to search for new sources in repeated observations of the same field. The wide range of timescales makes VLITE sensitive to both coherent and incoherent transient source classes. No new transients are found, allowing us to set stringent upper limits on transients at milli-jansky levels and at low frequencies where comparatively few such surveys have been carried out to date. An all-sky isotropic surface density of bursting radio transients with similar rates, durations, and intensities as the unusual transient GCRT J1745−3009, discovered in wide-field monitoring toward the Galactic center, is ruled out with high confidence. The resulting non-detections allows us to argue that this is a coherent source, whose properties most resemble the growing class of nulling pulsars. We end with a discussion of the future prospects for the detection of transients by VLITE and other experiments.
DISCOVERY OF A POSSIBLE COOL WHITE DWARF COMPANION FROM THE AllWISE MOTION SURVEY

Published: November 2016

We present optical and near-infrared spectroscopy of WISEA J061543.91−124726.8, which we rediscovered as a high motion object in the AllWISE survey. The spectra of this object are unusual; while the red optical (λ > 7000 Å) and near-infrared spectra exhibit characteristic TiO, VO, and H2O bands of a late-M dwarf, the blue portion of its optical spectrum shows a significant excess of emission relative to late-M-type templates. The excess emission is relatively featureless, with the exception of a prominent and very broad Na i D doublet. We find that no single, ordinary star can reproduce these spectral characteristics. The most likely explanation is an unresolved binary system of an M7 dwarf and a cool white dwarf. The flux of a cool white dwarf drops in the optical red and near-infrared, due to collision-induced absorption, thus allowing the flux of a late-M dwarf to show through. This scenario, however, does not explain the Na D feature, which is unlike that of any known white dwarf, but which could perhaps be explained via unusual abundance or pressure conditions.
HARD X-RAY ASYMMETRY LIMITS IN SOLAR FLARE CONJUGATE FOOTPOINTS
Authors: Daou Antoun G. , Alexander David
Published: November 2016

The transport of energetic electrons in a solar flare is modeled using a time-dependent one-dimensional Fokker–Planck code that incorporates asymmetric magnetic convergence. We derive the temporal and spectral evolution of the resulting hard X-ray (HXR) emission in the conjugate chromospheric footpoints, assuming thick target photon production, and characterize the time evolution of the numerically simulated footpoint asymmetry and its relationship to the photospheric magnetic configuration. The thick target HXR asymmetry in the conjugate footpoints is found to increase with magnetic field ratio as expected. However, we find that the footpoint HXR asymmetry saturates for conjugate footpoint magnetic field ratios ≥4. This result is borne out in a direct comparison with observations of 44 double-footpoint flares. The presence of such a limit has not been reported before, and may serve as both a theoretical and observational benchmark for testing a range of particle transport and flare morphology constraints, particularly as a means to differentiate between isotropic and anisotropic particle injection.
LONG-TERM TRENDS IN THE SOLAR WIND PROTON MEASUREMENTS
Authors: Elliott Heather A. , McComas David J. , DeForest Craig E.
Published: November 2016

We examine the long-term time evolution (1965–2015) of the relationships between solar wind proton temperature (T
p) and speed (V
p) and between the proton density (n
p) and speed using OMNI solar wind observations taken near Earth. We find a long-term decrease in the proton temperature–speed (T
p–V
p) slope that lasted from 1972 to 2010, but has been trending upward since 2010. Since the solar wind proton density–speed (n
p–V
p) relationship is not linear like the T
p–V
p relationship, we perform power-law fits for n
p–V
p. The exponent (steepness in the n
p–V
p relationship) is correlated with the solar cycle. This exponent has a stronger correlation with current sheet tilt angle than with sunspot number because the sunspot number maxima vary considerably from cycle to cycle and the tilt angle maxima do not. To understand this finding, we examined the average n
p for different speed ranges, and found that for the slow wind n
p is highly correlated with the sunspot number, with a lag of approximately four years. The fast wind n
p variation was less, but in phase with the cycle. This phase difference may contribute to the n
p–V
p exponent correlation with the solar cycle. These long-term trends are important since empirical formulas based on fits to T
p and V
p data are commonly used to identify interplanetary coronal mass ejections, but these formulas do not include any time dependence. Changes in the solar wind density over a solar cycle will create corresponding changes in the near-Earth space environment and the overall extent of the heliosphere.
THE ORBIT, ROTATION, AND GRANULATION OF THE G7 GIANT β Her
Authors: Gray David F.
Published: November 2016

The G7 IIIa single-lined spectroscopic binary, β Her, is studied with high-resolution, high-signal-to-noise spectra taken over 10 seasons from 23MR2000 to 10MY2009. Absolute radial velocities, corrected for convective blueshifts, are determined and new orbital parameters are derived. Line-depth ratios are used to measure temperature variation ∼2 K. A Fourier analysis is done for the line broadening, yielding a projected rotation velocity of 3.27 ± 0.20 km s−1 and a radial–tangential macroturbulence dispersion of 6.43 ± 0.08 km s−1. The “C” shaped bisector of Fe i
λ6253 has its blue-most point at a relative flux level of 0.52, consistent with what is expected from β Her’s absolute magnitude. The third-signature plot indicates granulation velocities 20% larger than the Sun’s. Mapping the λ6253 line bisector onto the third-signature curve results in a flux deficit of 12.6 ± 1.0% that can be interpreted as arising from a temperature difference between granules and inter-granular lanes of 132 K. The flux deficit peaks near 5.5 km s−1 from the line center, suggesting the velocity difference between granules and lanes is ∼20% larger than that found for recently analyzed K giants.

Galaxy mergers are important events that can determine the fate of a galaxy by changing its morphology, star formation activity and mass growth. Merger systems have commonly been identified from their disturbed morphologies, and we now can employ integral field spectroscopy to detect and analyze the impact of mergers on stellar kinematics as well. We visually classified galaxy morphology using deep images (

) taken by the Blanco 4 m telescope at the Cerro Tololo Inter-American Observatory. In this paper we investigate 63 bright (

) spectroscopically selected galaxies in Abell 119, of which 53 are early type and 20 show a disturbed morphology by visual inspection. A misalignment between the major axes in the photometric image and the kinematic map is conspicuous in morphologically disturbed galaxies. Our sample is dominated by early-type galaxies, yet it shows a surprisingly tight Tully–Fisher relation except for the morphologically disturbed galaxies which show large deviations. Three out of the eight slow rotators in our sample are morphologically disturbed. The morphologically disturbed galaxies are generally more asymmetric, visually as well as kinematically. Our findings suggest that galaxy interactions, including mergers and perhaps fly-bys, play an important role in determining the orientation and magnitude of a galaxy’s angular momentum.

Histoire de Laura : une protestation du soi
Authors: Conesa Élisabeth
Published: November 2016

Le soi est présent chez l’enfant dès le début de sa vie. Celui-ci n’a pas les mots, mais sous la poussée du soi, soi corporel et soi relationnel œuvrant de concert, il peut protester et se faire entendre. En reprenant le cours d’une thérapie d’enfant, l’auteure donne à voir une protestation du soi qui est « authentifiée » par l’analyste dans sa fonction de soi relationnel.
De la difficulté à devenir
Authors: Cametz Olivier
Published: November 2016

Lorsque la négativité du patient se déploie dans le champ transférentiel, l’analyste peut disposer de repères théorico-cliniques dans la psychanalyse jungienne. À la suite des travaux de Carl Gustav Jung, Michael Fordham et Donald Kalsched se sont attachés à conceptualiser l’interaction analyste/patient lorsque le lien transférentiel évolue dans ses soubassements inconscients les plus sombres. Les travaux de Murray Stein sur la notion kleinienne d’envie haineuse dans l’optique de la théorie jungienne de l’individuation sont également abordés pour expliciter l’incidence des mouvements projectifs au cœur du transfert négatif sur le processus analytique. À partir d’un exemple clinique l’auteur commente les mécanismes d’intégration du négatif dans le champ transférentiel qui permettent une reprise de l’évolution thérapeutique au cours d’une analyse.

Carl Gustav Jung et Friedrich Hölderlin
Authors: Liard Véronique
Published: November 2016

C. G. Jung considérait que Hölderlin, en tant que poète, lui avait apporté encore plus que Goethe, mais l’intérêt qu’il lui portait était d’ordre essentiellement psychologique. Pour lui, les poèmes hölderliniens retracent comment, quand une conscience n’évolue pas, elle s’enfonce dans sa propre profondeur et se trouve peu à peu submergée par l’inconscient. Dans l’œuvre de Jung, régulièrement, Hölderlin revient à la fois comme une mise en garde et un message d’espoir. Cet avertissement et cet encouragement se fondent sur ce que Jung a lui-même vécu lors de sa confrontation avec l’inconscient.
La réception perdue : La monadologie démontrée de Michael Gottlieb Hansch
Authors: Pelletier Arnaud
Published: November 2016

La première réception de la philosophie leibnizienne ne s’est certainement pas réduite à sa reprise dans le soi-disant « système leibnizo-wolffien », qui fut le prisme majoritaire, et déformant, de la lecture de Leibniz au xviii e   siècle. Au contraire, Michael Gottlieb Hansch, traducteur de la Monadologie en latin, essaya de s’élever contre cette réappropriation de l’héritage leibnizien et de présenter le « vrai » Leibniz hors de tout système leibnizo-wolffien. Il se proposa alors d’expliciter les propositions parfois denses de la Monadologie à partir de Leibniz lui-même, et en particulier de leur correspondance privée. Sa correspondance l’incite aussi à proposer une lecture « platonisante » de la Monadologie . À bien des égards, cette réception perdue révèle simplement des aspects encore largement méconnus de la philosophie leibnizienne.
Idéalité de la monade et réalité de la « monadologie » : sur un lieu commun de l’interprétation
Authors: Fichant Michel
Published: November 2016

Depuis Léon Brunschvicg s’est établie une sorte de lieu commun de l’interprétation de la métaphysique de Leibniz, dont la cohérence serait compromise par la contradiction entre la monade, pour qui l’espace est idéal, et la « monadologie » ou système de toutes les monades coexistantes, qui présupposerait un réalisme de l’espace. Dans cet article, l’argument de Brunschvicg est reconstitué, puis critiqué par la restitution de la pensée réelle de Leibniz sur les rapports entre monade et espace : on ne doit en aucun cas se représenter la pluralité des monades comme une multiplicité spatiale – l’espace est un ordre non des substances simples, mais des phénomènes, – seule l’union constante et universelle de chaque monade à un corps organique permet de parler d’un « point de vue », qui n’est autre que la localisation de ce corps parmi les autres et non de la monade qui, en tant que telle, n’a pas de lieu.
Au-delà de la philosophie
Authors: Gädeke Nora , Leloutre Françoise
Published: November 2016

Dans l’édition historique et critique de Leibniz, la série I ( Correspondance générale, politique et historique ) est la série la plus volumineuse, la plus avancée et aussi la moins connue. Le fait qu’à côté des noms célèbres et des grandes problématiques qui concernent les autres séries de correspondances (philosophie ainsi que mathématiques et physique), elle contienne une foule de petites nouvelles et de correspondants de « second rang » a conduit dans le cours de l’édition à une critique fondamentale. Cependant, non seulement parce que la multitude des thèmes reflète l’état du discours de l’époque, en deçà même du mainstream , et qu’entrent en scène nombre de « lettrés » dont l’activité serait autrement oubliée. Mais la conservation exceptionnellement bonne du fonds épistolaire rend aussi possible de suivre en détail le parcours des nouvelles. L’édition de Leibniz devient ainsi une ressource pour la République des Lettres et un atelier pour les recherches sur la culture épistolaire de l’époque.
A Readiness Index for Marketing Analytics
Authors: Reyes-Mercado Pável
Published: November 2016

The marketing analytics function has received increasing attention from managers as information processing has permeated all marketing domain. However, value is realized once data is properly processed and firms develop and activate consumers and customers' insights to make decisions, that is, during the implementation stage of the marketing analytics function. This study aims to propose a research model to analyse how ready are organizations to reap the benefits of implementing the marketing analytics function and understand its impact on the overall marketing performance. The model is derived from the Resource-Based view of the firm, a research perspective that argues that for a firm to reach a sustainable competitive advantage, its key assets –the marketing function– has to be: valuable, rare, inimitable, and the organisation has to be capable of exploit such assets. Managerial and research implications are discussed and further research avenues are offered.
Services Trade in Emerging Market Economies
Authors: Mandal Raju , Nath Hiranya K.
Published: November 2016

Global trade in services has increased significantly over last three decades. Earlier, the growth was confined primarily to trade among advanced economies. In more recent times, even developing countries – especially, the emerging market economies (EMEs) – have experienced substantial increase in services trade. Services trade still accounts for only a small share of national income in most EMEs. However, one important trend has been the rapid growth of information-intensive services (IISs). This chapter examines the growth and patterns of services exports and imports from and to a number of EMEs. The analysis indicates that the importance of services trade has been growing for most EMEs. Further, among the EMEs, China, India, and Korea are the most dominant players in services exports and imports. For China, both export and import shares have been rising while for India the export share has been consistently rising. This chapter further discusses some of the intuitively plausible explanations for the growth of trade in services in general and in IISs in particular. It also discusses some of the challenges associated with the growth of IISs trade.
Consumer Impetuosity in M-Commerce
Authors: Bojorges Moctezuma Natasha Patricia
Published: November 2016

Existing research on impulsive buying focuses mainly on goods displayed in physical spaces and services delivered face to face. This paper aims to present a novel approach to analyze the impulsiveness on purchase through mobile devices by the development of a reliable and valid scale of impulsiveness in the context of mobile commerce, also known as m-commerce. To achieve the aforementioned research purpose, this paper views impulsiveness in m-commerce as a holistic process encompassing personal traits, stimulus level, and, product attributes to understand the motivational, emotional, and cognitive factors underlying the impulse buying journey and purchase decision on the basis of a scale to measure the construct. The paper concludes with a discussion on its conceptual and managerial contributions and interesting directions for future research.

Technology is entwined in almost every part of one's lives. Today's students are using more technology than ever before. Information technology has revolutionized every industry and especially the banking industry. Tremendous improvements in technology have taken place in the Indian banking sector. Among all, Mobile Banking (m-banking) is the recent phenomenon that changed country's banking system. Students, being considered as most technically knowledgeable make most use of mobile banking services among all the banking customers. Therefore, the focus is particularly towards the young students engaging in m-banking services and to evaluate the factors that influence them to adopt m-banking. The study considers extended Technology Adoption Model (TAM) to measure the impact of the factors on adoption of m-banking. For the study, data was collected through questionnaire from 217 students of Western Rajasthan. The result of this research would provide valuable information to service providers in order to improve their m-banking services.
