Financial Reporting Quality and Uncertainty about Credit Risk among Ratings Agencies
Authors: Akins Brian 
Published: October 2017

ABSTRACT
This study finds that better reporting quality is associated with less uncertainty about credit risk as captured by disagreement among the credit rating agencies. The results also show that reporting quality is more important in reducing uncertainty when debt market participants have less access to private information. To mitigate endogeneity concerns, I use the quasi-natural experiment induced by a change in accounting standards that improved reporting quality. Implementation of the standard led to less disagreement among the rating agencies. Overall, this study contributes to the literature on the impact of reporting quality on debt markets and intermediaries.
Influential Chief Marketing Officers and Management Revenue Forecasts
Authors: Koo David S. , Lee Dongyoung 
Published: October 2017

ABSTRACT
We examine the role of the chief marketing officer (CMO) in corporate voluntary disclosure of future revenues. Using a sample of S&P 1500 firms for the period from 2003 to 2011, we find that the presence of an influential CMO in top management is positively associated with the likelihood of a firm issuing a management revenue forecast. We also find that firms with an influential CMO provide more accurate revenue forecasts than other firms. These findings extend to long-window change analyses and are robust to the use of a propensity score matched-pair approach. Overall, the results are consistent with the notion that CMO influence in top management appears to play an important role in voluntary revenue disclosures.

Abstract
Higher education, as an institution that generates the nation's next future leader, is no longer burdened with merely providing knowledge alone. Human resource competitiveness was being one of higher education responsibility to complete, to achieve a great quality of their graduates. Hope that emerged from the students on the fulfillment of obligations towards their university becomes something that can not be separated from the quality of the graduates. Psychological contract as a concept that can explain it, has not been widely studied in a higher education setting especially in Indonesia. The number of measuring instruments has its version on some theoretical models raises curiosity as to what is actually appropriate. Through the method of literature review, it was carried out a critical discussion of the components in the measurement of psychological contract at higher education institutions. The exposure in understanding the dynamics of inter-dimensional and determine the appropriate model based on the characteristics of each academic institution. At least, measurement of psychological contract used in higher education setting should be both of promissory (transactional) and non-promissory (relational) dimension. Surely, it always needs to adjust to the conditions and situations relevantly in each institution. Therefore, it would be possible to bring various indicators in each of dimension.
The ShortMAC: Minimum Important Change of a Reduced Version of the Western Ontario and McMaster Universities Osteoarthritis Index
Authors: Abbott J. Haxby , Hobbs Catherine , Gwynne-Jones David 
Published: October 2017

Study Design Clinical measurement study; secondary analysis of randomized clinical trial data. Background A 12-item shortened version (ShortMAC) of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), a condition-specific, patient-reported osteoarthritis index, has been derived, published, and validated. The minimum important change (MIC) of the ShortMAC has not been reported or compared with the traditional 24-item WOMAC. Objectives To investigate the MIC of the 12-item ShortMAC and the traditional 24-item WOMAC across 3 levels of patient-perceived global change. Methods The Management of OsteoArthritis Trial cohort of 206 consecutive patients with knee or hip osteoarthritis was assessed at the initial visit and after 9 weeks of physical therapy (n = 155) or usual medical care (n = 51). The global rating of change instrument, assessed at the 9-week visit, provided the anchor. The MIC was calculated using receiver operating characteristic curve methodology for the ShortMAC and the traditional WOMAC, across 3 levels of patient-perceived change (small, medium, and large change) defined by the global rating of change. Results The MICs for the ShortMAC and traditional WOMAC (both transformed to a scale from 0 to 100) were 7.9 and 9.8 points for small change, 8.4 and 9.8 points for medium change, and 12.1 and 10.1 points for large change, respectively. The MICs of the pain and function subscales are also reported for small, medium, and large changes. Conclusion The lower point estimates for the MIC of the ShortMAC compared with that of the traditional WOMAC, using conventional definitions of MIC and half the number of items, indicate greater efficiency for use in clinical trials and reduced patient burden.

Middle income countries? An alternative development taxonomy of Latin America and the Caribbean
Authors: Tezanos-Vázquez Sergio , Quiñones-Montellano Ainoa 
Published: October 2017

Although it is not asy to classify countries according to their levels of development –mainly because the concept of “human development” is complex and multidimensional –, the most widespread classification is just the simplest one, based on income per capita levels. According to this classification, most of the Latin America and the Caribbean (LAC) countries are located in the world middle-income strata. This paper proposes an alternative “development taxonomy” for LAC middle-income countries. Using a cluster analysis we identify and characterize three groups of countries in relation to 10 main “development gaps”: the most advanced countries (Mexico, Chile, Argentina, Venezuela, Uruguay and Brasil), the middle-development countries (Panama, Costa Rica, Colombia, Jamaica, Dominican Republic, Ecuador, Peru, Belize, El Salvador, Paraguay and Guyana) and those countries with the greatest development challenges (Guatemala, Bolivia, Honduras and Nicaragua).CITE AS:Tezanos-Vázquez, S., Quiñones-Montellano, A.

Phylogenetic patterns of foliar mineral nutrient accumulation among gypsophiles and their relatives in the Chihuahuan Desert
Authors: Muller Clare T. , Moore Michael J. , Feder Zoë , Tiley Helene , Drenovsky Rebecca E. 
Published: October 2017

PREMISE OF THE STUDY:Gypsum endemism in plants (gypsophily) is common on gypsum outcrops worldwide, but little is known about the functional ecology of Chihuahuan Desert gypsophiles. We investigated whether leaf chemistry of gypsophile lineages from the northern Chihuahuan Desert are similar to leaves of related nonendemic (gypsovag) species relative to their soil chemistry. We expected widely distributed gypsophiles (hypothesized to be older lineages on gypsum) would have distinct leaf chemistry from narrowly distributed, relatively younger lineages endemic to gypsum and gypsovags, reflecting adaptation to gypsum.METHODS:We collected leaves from 23 gypsophiles and related nonendemic taxa growing on nongypsum soils. Soils and leaves were analyzed for Ca, S, Mg, K, N, and P. Leaf gypsum was assessed using Fourier transform infrared spectroscopy.KEY RESULTS:Most widespread gypsophile lineages that are hypothesized to be relatively old accumulate foliar S, Ca, and gypsum, but younger gypsophile lineages and closely related gypsovags do not. Young, narrowly distributed gypsophile lineages have leaf chemical signatures similar to nonendemic congeners and confamilials.CONCLUSIONS:Our data suggest multiple adaptive mechanisms support life on gypsum in Chihuahuan Desert gypsophiles. Most widespread gypsophiles are specialized for life on gypsum, likely due to shared abilities to accumulate and assimilate S and Ca in leaves. In contrast, narrowly distributed gypsophiles may have mechanisms to exclude excess S and Ca from their leaves, preventing toxicity. Future work will investigate the nutrient accumulation and exclusion patterns of other plant organs to determine at what level excess S and Ca uptake is restricted for young‐lineage gypsophiles and gypsovags.

Abstract
We present the first stable release of Halotools (v0.2), a community-driven Python package designed to build and test models of the galaxy-halo connection. Halotools provides a modular platform for creating mock universes of galaxies starting from a catalog of dark matter halos obtained from a cosmological simulation. The package supports many of the common forms used to describe galaxy-halo models: the halo occupation distribution, the conditional luminosity function, abundance matching, and alternatives to these models that include effects such as environmental quenching or variable galaxy assembly bias. Satellite galaxies can be modeled to live in subhalos or to follow custom number density profiles within their halos, including spatial and/or velocity bias with respect to the dark matter profile. The package has an optimized toolkit to make mock observations on a synthetic galaxy population—including galaxy clustering, galaxy–galaxy lensing, galaxy group identification, RSD multipoles, void statistics, pairwise velocities and others—allowing direct comparison to observations. Halotools is object-oriented, enabling complex models to be built from a set of simple, interchangeable components, including those of your own creation. Halotools has an automated testing suite and is exhaustively documented on http://halotools.readthedocs.io, which includes quickstart guides, source code notes and a large collection of tutorials. The documentation is effectively an online textbook on how to build and study empirical models of galaxy formation with Python.
The Solar Neighborhood. XLII. Parallax Results from the CTIOPI 0.9 m Program—Identifying New Nearby Subdwarfs Using Tangential Velocities and Locations on the H–R Diagram

Published: October 2017

Abstract
Parallaxes, proper motions, and optical photometry are presented for 51 systems consisting of 37 cool subdwarf and 14 additional high proper motion systems. Thirty-seven systems have parallaxes reported for the first time, 15 of which have proper motions of at least 1″ yr−1. The sample includes 22 newly identified cool subdwarfs within 100 pc, of which three are within 25 pc, and an additional five subdwarfs from 100 to 160 pc. Two systems—LSR 1610-0040 AB and LHS 440 AB—are close binaries exhibiting clear astrometric perturbations that will ultimately provide important masses for cool subdwarfs. We use the accurate parallaxes and proper motions provided here, combined with additional data from our program and others, to determine that effectively all nearby stars with tangential velocities greater than 200 km s−1 are subdwarfs. We compare a sample of 167 confirmed cool subdwarfs to nearby main sequence dwarfs and Pleiades members on an observational Hertzsprung–Russell diagram using M

V
versus (V − K

s
) to map trends of age and metallicity. We find that subdwarfs are clearly separated for spectral types K5–M5, indicating that the low metallicities of subdwarfs set them apart in the H–R diagram for (V − K

s
) = 3–6. We then apply the tangential velocity cutoff and the subdwarf region of the H–R diagram to stars with parallaxes from Gaia Data Release 1 and the MEarth Project to identify a total of 29 new nearby subdwarf candidates that fall clearly below the main sequence.

Abstract
We report the first results from a search for transiting warm Jupiter exoplanets—gas giant planets receiving stellar irradiation below about 108 erg s−1 cm−2, equivalent to orbital periods beyond about 10 days around Sun-like stars. We have discovered two transiting warm Jupiter exoplanets initially identified as transiting candidates in K2 photometry. K2-114b has a mass of

, a radius of

, and an orbital period of 11.4 days. K2-115b has a mass of

, a radius of

, and an orbital period of 20.3 days. Both planets are among the longest-period transiting gas giant planets with a measured mass, and they are orbiting relatively old host stars. Both planets are not inflated, as their radii are consistent with theoretical expectations. Their position in the planet radius–stellar irradiation diagram is consistent with the scenario where the radius–irradiation correlation levels off below about 108 erg s−1 cm−2, suggesting that for warm Jupiters stellar irradiation does not play a significant role in determining the planet radius. We also report our identification of another K2 transiting warm Jupiter candidate, EPIC 212504617, as a false positive.

Published: October 2017

Abstract
We present results of a multi-epoch monitoring program on variability of 6 cm formaldehyde (H2CO) masers in the massive star-forming region NGC 7538 IRS 1 from 2008 to 2015, conducted with the Green Bank Telescope, the Westerbork Radio Telescope , and the Very Large Array. We found that the similar variability behaviors of the two formaldehyde maser velocity components in NGC 7538 IRS 1 (which was pointed out by Araya and collaborators in 2007) have continued. The possibility that the variability is caused by changes in the maser amplification path in regions with similar morphology and kinematics is discussed. We also observed 12.2 GHz methanol and 22.2 GHz water masers toward NGC 7538 IRS 1. The brightest maser components of CH3OH and H2O species show a decrease in flux density as a function of time. The brightest H2CO maser component also shows a decrease in flux density and has a similar LSR velocity to the brightest H2O and 12.2 GHz CH3OH masers. The line parameters of radio recombination lines and the 20.17 and 20.97 GHz CH3OH transitions in NGC 7538 IRS 1 are also reported. In addition, we observed five other 6 cm formaldehyde maser regions. We found no evidence of significant variability of the 6 cm masers in these regions with respect to previous observations, the only possible exception being the maser in G29.96−0.02. All six sources were also observed in the

isotopologue transition of the 6 cm H2CO line;

absorption was detected in five of the sources. Estimated column density ratios [

Charge Exchange of Highly Charged Ne and Mg Ions with H and He
Authors: Lyons D. , Cumbee R. S. , Stancil P. C. 
Published: October 2017

Abstract
Cross sections for single electron capture (SEC), or charge exchange (CX), in collisions of Ne(8–10)+ and Mg(8–12)+ with H and He, are computed using an approximate multichannel Landau–Zener (MCLZ) formalism. Final-state-resolved cross sections for the principal (n), orbital angular momentum (ℓ), and where appropriate, total spin angular momentum (S) quantum numbers are explicitly computed, except for the incident bare ions Ne10+ and Mg12+. In the latter two cases,

-resolution is obtained from analytical ℓ-distribution functions applied to n-resolved MCLZ cross sections. In all cases, the cross sections are computed over the collision energy range 1 meV/u to 50 keV/u with LZ parameters estimated from atomic energies obtained from experiment, theory, or, in the case of high-lying Rydberg levels, estimated with a quantum defect approach. Errors in the energy differences in the adiabatic potentials at the avoided crossing distances give the largest contribution to the uncertainties in the cross sections, which are expected to increase with decreasing cross section magnitude. The energy differences are deduced here with the Olson–Salop–Tauljberg radial coupling model. Proper selection of an ℓ-distribution function for bare ion collisions introduces another level of uncertainty into the results. Comparison is made to existing experimental or theoretical results when available, but such data are absent for most considered collision systems. The

-resolved SEC cross sections are used in an optically thin cascade simulation to predict X-ray spectra and line ratios that will aid in modeling the X-ray emission in environments where CX is an important mechanism. Details on a MCLZ computational package, Stueckelberg, are also provided.

Abstract
Comparison of interstellar medium (ISM) absorption in the UV spectrum of LS 4825, a B1 Ib−II star d = 21 ± 5 kpc from the Sun toward l = 1.°67 and b = −6.°63, with ISM absorption toward an aligned foreground star at d < 7.0 ± 1.7 kpc, allows us to isolate and study gas associated with the Milky Way nuclear wind. Spectra from the Space Telescope Imaging Spectrograph show low-ionization absorption out to d < 7 kpc (e.g., O i, C ii, Mg ii, Si ii, Fe ii, S ii) only between 0 and 40 km s−1, while absorption at d > 7 kpc, ∼1 kpc below the Galactic plane, is complex and spans −290 to +94 km s−1. The intermediate and high ions Si iii, C iv, Si iv, and N v show extremely strong absorption with multiple components from −283 to 107 km s−1, implying that the ISM ∼1 kpc below the Galactic center has a substantial reservoir of plasma and more gas containing C iv and N v than in the Carina OB1 association at z = 0 kpc. Abundances and physical conditions are presented for many absorption components. The high ion absorption traces cooling transition temperature plasma probably driven by the outflowing hot gas, while the extraordinarily large thermal pressure, p/k ∼ 105 cm−3 K−1, in an absorption component at −114 km s−1 probably arises from the ram pressure of the outflowing hot gas. The observations are consistent with a flow whose ionization structure in the high ions can be understood through a combination of nonequilibrium radiative cooling and turbulent mixing.
Une frontière pour se reconnaître et vivre ensemble. Réflexions sur la territorialité dans quelques récits de l’Ancien Testament
Authors: Nocquet Dany 
Published: October 2017

Par rapport à la thématique de la frontière, l’Ancien Testament repense la notion d’appartenance territoriale. La représentation du « pays promis », si souvent situé entre Jourdain et Méditerranée, n’a guère de soutien scripturaire dans le Pentateuque. Plusieurs récits, au contraire, déterritorialisent la notion de « terre promise ». Elle se place aussi bien en pays transjordanien, philistin, égyptien, que madianite ou israélite. Pour les derniers éditeurs du Pentateuque, la « terre promise », qui va de la Mésopotamie à l’Égypte (Gn 15), est l’occasion de dire la « dette » d’Israël à l’égard de ses voisins, de ses parentés étrangères, tout en assumant le bien-fondé des frontières pour vivre des identités différentes.

Abstract
Type I IFN and nucleic acid–sensing TLRs are both strongly implicated in the pathogenesis of lupus, with most patients expressing IFN-induced genes in peripheral blood cells and with TLRs promoting type I IFNs and autoreactive B cells. About a third of systemic lupus erythematosus patients, however, lack the IFN signature, suggesting the possibility of type I IFN–independent mechanisms. In this study, we examined the role of type I IFN and TLR trafficking and signaling in xenobiotic systemic mercury-induced autoimmunity (HgIA). Strikingly, autoantibody production in HgIA was not dependent on the type I IFN receptor even in NZB mice that require type I IFN signaling for spontaneous disease, but was dependent on the endosomal TLR transporter UNC93B1 and the endosomal proton transporter, solute carrier family 15, member 4. HgIA also required the adaptor protein-3 complex, which transports TLRs from the early endosome to the late endolysosomal compartments. Examination of TLR signaling pathways implicated the canonical NF-κB pathway and the proinflammatory cytokine IL-6 in autoantibody production, but not IFN regulatory factor 7. These findings identify HgIA as a novel type I IFN–independent model of systemic autoimmunity and implicate TLR-mediated NF-κB proinflammatory signaling from the late endocytic pathway compartments in autoantibody generation.
