Abstract
The distributions of stars, gas, and dark matter in disk galaxies provide important constraints on galaxy formation models, particularly on small spatial scales (<1 kpc). We have designed the RSS Imaging spectroscopy Nearby Galaxy Survey (RINGS) to target a sample of 19 nearby spiral galaxies. For each of these galaxies, we obtain and model Hα and H i 21 cm spectroscopic data as well as multi-band photometric data. We intend to use these models to explore the underlying structure and evolution of these galaxies in a cosmological context, as well as whether the predictions of ΛCDM are consistent with the mass distributions of these galaxies. In this paper, we present spectroscopic imaging data for 14 of the RINGS galaxies observed with the medium spectral resolution Fabry–Pérot etalon on the Southern African Large Telescope. From these observations, we derive high spatial resolution line-of-sight velocity fields of the Hα line of excited hydrogen, as well as maps and azimuthally averaged profiles of the integrated Hα and [N ii] emission and oxygen abundances. We then model these kinematic maps with axisymmetric models, from which we extract rotation curves and projection geometries for these galaxies. We show that our derived rotation curves agree well with other determinations, and the similarity of the projection angles with those derived from our photometric images argues against these galaxies having intrinsically oval disks.
Isotopic Dichotomy among Meteorites and Its Bearing on the Protoplanetary Disk
Authors: Scott Edward R. D. , Krot Alexander N. , Sanders Ian S. 
Published: February 2018

Abstract
Whole rock Δ17O and nucleosynthetic isotopic variations for chromium, titanium, nickel, and molybdenum in meteorites define two isotopically distinct populations: carbonaceous chondrites (CCs) and some achondrites, pallasites, and irons in one and all other chondrites and differentiated meteorites in the other. Since differentiated bodies accreted 1–3 Myr before the chondrites, the isotopic dichotomy cannot be attributed to temporal variations in the disk. Instead, the two populations were most likely separated in space, plausibly by proto-Jupiter. Formation of CCs outside Jupiter could account for their characteristic chemical and isotopic composition. The abundance of refractory inclusions in CCs can be explained if they were ejected by disk winds from near the Sun to the disk periphery where they spiraled inward due to gas drag. Once proto-Jupiter reached 10–20 M
⊕, its external pressure bump could have prevented millimeter- and centimeter-sized particles from reaching the inner disk. This scenario would account for the enrichment in CCs of refractory inclusions, refractory elements, and water. Chondrules in CCs show wide ranges in Δ17O as they formed in the presence of abundant 16O-rich refractory grains and 16O-poor ice particles. Chondrules in other chondrites (ordinary, E, R, and K groups) show relatively uniform, near-zero Δ17O values as refractory inclusions and ice were much less abundant in the inner solar system. The two populations were plausibly mixed together by the Grand Tack when Jupiter and Saturn migrated inward emptying and then repopulating the asteroid belt with roughly equal masses of planetesimals from inside and outside Jupiter’s orbit (S- and C-type asteroids).
Calvera: A Low-mass Strangeon Star Torqued by Debris Disk?

Published: February 2018

Abstract
Calvera is a unique

isolated pulsar, because it cannot be detected by radio, optical, and gamma-rays; however, it is detectable through the purely thermal emission in soft X-rays. It is suggested that Calvera could be an ordinary middle-aged pulsar with significant magnetospheric activity at a large distance. Alternatively, it is proposed in this paper that Calvera is a low-mass strangeon star with an inactive magnetosphere (dead). In this scenario, we jointly fit the spectra obtained by the XMM-Newton Observatory and the Chandra X-ray Observatory with the strangeon star atmosphere model. The spectral model is successful in explaining the radiation properties of Calvera and X-ray dim isolated neutron stars, both of which show similar observation features. Within the dead pulsar picture, Calvera might have a high temperature at

, possess a small stellar radius,

, presumably have a small magnetic field,

, and is probably braked by the fallback disk accretion. Future advanced facilities may provide unique opportunities to understand the real nature of Calvera.

Abstract
We propose a novel method to constrain turbulence and bulk motions in massive galaxies, galaxy groups, and clusters, exploring both simulations and observations. As emerged in the recent picture of top-down multiphase condensation, hot gaseous halos are tightly linked to all other phases in terms of cospatiality and thermodynamics. While hot halos (∼107 K) are perturbed by subsonic turbulence, warm (∼104 K) ionized and neutral filaments condense out of the turbulent eddies. The peaks condense into cold molecular clouds (<100 K) raining in the core via chaotic cold accretion (CCA). We show that all phases are tightly linked in terms of the ensemble (wide-aperture) velocity dispersion along the line of sight. The correlation arises in complementary long-term AGN feedback simulations and high-resolution CCA runs, and is corroborated by the combined Hitomi and new Integral Field Unit measurements in the Perseus cluster. The ensemble multiphase gas distributions (from the UV to the radio band) are characterized by substantial spectral line broadening (σ

v,los ≈ 100–200

) with a mild line shift. On the other hand, pencil-beam detections (as H i absorption against the AGN backlight) sample the small-scale clouds displaying smaller broadening and significant line shifts of up to several 100

(for those falling toward the AGN), with increased scatter due to the turbulence intermittency. We present new ensemble σ

v,los of the warm Hα+[N ii] gas in 72 observed cluster/group cores: the constraints are consistent with the simulations and can be used as robust proxies for the turbulent velocities, in particular for the challenging hot plasma (otherwise requiring extremely long X-ray exposures). Finally, we show that the physically motivated criterion C ≡ t
cool/t
eddy ≈ 1 best traces the condensation extent region and the presence of multiphase gas in observed clusters and groups. The ensemble method can be applied to many available spectroscopic data sets and can substantially advance our understanding of multiphase halos in light of the next-generation multiwavelength missions.

Abstract
Stellar fundamental parameters are important in the asteroseismic study of Kepler light curves. However, the most used estimates in the Kepler Input Catalog (KIC) are not accurate enough for hot stars. Using a sample of B stars from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spectral survey, we confirmed the systematic underestimation in the KIC effective temperature and overestimation in KIC surface gravity. The good agreement between LAMOST and other follow-up observations proved the accuracy of effective temperature and surface gravity of B stars derived from LAMOST low-resolution spectra. By searching through LAMOST data, we found four misclassified main-sequence B stars in the Kepler field, which had been previously classified as A-type variables. We present spectroscopic and detailed frequency analysis of these four stars based on LAMOST spectra and Kepler photometry.
The Updated Multiple Star Catalog
Authors: Tokovinin Andrei 
Published: February 2018

Abstract
The catalog of hierarchical stellar systems with three or more components is an update of the original 1997 version. For 2000 hierarchies, the new Multiple Star Catalog (MSC) provides distances, component masses and periods, and supplementary information (astrometry, photometry, identifiers, orbits, notes). The MSC content and format are explained, and its incompleteness and strong observational selection are stressed. Nevertheless, the MSC can be used for statistical studies and is a valuable source for planning observations of multiple stars. Rare classes of stellar hierarchies found in the MSC (with six or seven components, extremely eccentric orbits, planar and possibly resonant orbits, hosting planets) are briefly presented. High-order hierarchies have smaller velocity dispersion compared to triples and are often associated with moving groups. The paper concludes with an analysis of the ratio of periods and separations between inner and outer subsystems. In wide hierarchies, the ratio of semimajor axes, estimated statistically, is distributed between 3 and 300, with no evidence of dynamically unstable systems.
J0023+0307: A Mega Metal-poor Dwarf Star from SDSS/BOSS*
Authors: Aguado David S. , Prieto Carlos Allende , Hernández Jonay I. González , Rebolo Rafael 
Published: February 2018

Abstract
Only a handful of stars have been identified with an iron abundance [Fe/H] < −5, and only one at [Fe/H] < −7. These stars have very large carbon-to-iron ratios, with

∼ 7.0, most likely due to fallback in core-collapse supernovae, which makes their total metallicity Z much higher than their iron abundances. The failure to find population III stars, those with no metals, has been interpreted, with support from theoretical modeling, as the result of a top-heavy initial mass function. With zero or very low metal abundance limiting radiative cooling, the formation of low-mass stars could be inhibited. Currently, the star SDSS J1029+1729 sets the potential metallicity threshold for the formation of low-mass stars at

. In our quest to push down the metallicity threshold we have identified SDSS J0023+0307, a primitive star with T
eff = 6188 ± 84 K, and

, an upper limit [Fe/H] < −6.6, and a carbon abundance A(C) < 6.3. We find J0023+0307 to be one of the two most iron-poor stars known, and it exhibits less carbon that most of the stars at [Fe/H] < −5.
L’apport des théories de la motivation pour comprendre l’appropriation des TI
Authors: Tsoni Christina 
Published: February 2018

Cette recherche adopte une approche motivationnelle selon laquelle tout individu s’engage dans l’appropriation d’une technologie dès lors qu’il y trouve un « intérêt » intrinsèque. Cet intérêt n’étant pas systématique chez l’utilisateur professionnel, les interventions managériales sont nécessaires pour extrinsèquement le stimuler et, par ce biais, éviter le risque de non appropriation. Sur ce postulat nous proposons un modèle de l’appropriation individuelle d’une technologie professionnelle intégrant les niveaux individuel et managérial. Au niveau individuel deux variables explicatives de l’appropriation sont assimilées à des facteurs de motivation intrinsèque reflétant l’intérêt individuel pour la technologie (le Bénéfice ressenti et l’Avantage relatif de la technologie). Au niveau managérial trois interventions managériales-type (Formation, Assistance technique et Communication interne) sont assimilées à des leviers de motivation extrinsèque à effet modérateur. Le modèle est testé à travers une étude quantitative par questionnaire. 332 questionnaires ont été collectés et analysés sur Amos 22. Les résultats de la recherche distinguent entre deux types d’intervention managériale en matière d’appropriation : les interventions managériales à effet motivationnel et les interventions à effet cognitif.
Disorderly Women and the Order of God
Authors: Connolly Michele A. 
Published: February 2018

Michele A. Connolly reads the Gospel of Mark through a postcolonial, feminist lens. Post-colonial analysis links the Gospel of Mark, produced in the context of the Roman Empire with contemporary Australia, established initially as a colony of the British Empire. Feminist analysis of texts from two foundational events in Australian colonial history reveals that women in such texts tend to be marginalised, silenced and denigrated, because imperialist sexism, both ancient and modern, perceives women as a threat to the order that males alone can impose on the world
The Gospel of Mark portrays Jesus bringing the order of the Reign of God to combat the disorder of apocalyptic evil. Jesus’ task is a markedly male project against which 11 female characters are portrayed as disorderly distractions who are managed by being marginalised, silenced and denigrated.This contradicts Jesus’ message of mutual service and non-domination. In his death under apocalyptic power, Jesus is depicted as isolated, silenced and denigrated.This subtly associates femaleness with chaos, failure and disgrace
Sensitivity of the Eocene climate to CO2 and orbital variability
Authors: Keery John S. , Holden Philip B. , Edwards Neil R. 
Published: February 2018

Abstract. The early Eocene, from about 56 Ma, with high atmospheric
CO2 levels, offers an analogue for the response of the Earth's climate
system to anthropogenic fossil fuel burning. In this study, we present an
ensemble of 50 Earth system model runs with an early Eocene palaeogeography
and variation in the forcing values of atmospheric CO2 and the Earth's
orbital parameters. Relationships between simple summary metrics of model
outputs and the forcing parameters are identified by linear modelling,
providing estimates of the relative magnitudes of the effects of atmospheric
CO2 and each of the orbital parameters on important climatic features,
including tropical–polar temperature difference, ocean–land temperature
contrast, Asian, African and South (S.) American monsoon rains, and climate
sensitivity. Our results indicate that although CO2 exerts a dominant
control on most of the climatic features examined in this study, the orbital
parameters also strongly influence important components of the
ocean–atmosphere system in a greenhouse Earth. In our ensemble, atmospheric
CO2 spans the range 280–3000 ppm, and this variation accounts for over
90 % of the effects on mean air temperature, southern winter
high-latitude ocean–land temperature contrast and northern winter
tropical–polar temperature difference. However, the variation of precession
accounts for over 80 % of the influence of the forcing parameters on the
Asian and African monsoon rainfall, and obliquity variation accounts for over
65 % of the effects on winter ocean–land temperature contrast in high
northern latitudes and northern summer tropical–polar temperature
difference. Our results indicate a bimodal climate sensitivity, with values
of 4.36 and 2.54 ∘C, dependent on low or high states of atmospheric
CO2 concentration, respectively, with a threshold at approximately
1000 ppm in this model, and due to a saturated vegetation–albedo feedback.
Our method gives a quantitative ranking of the influence of each of the
forcing parameters on key climatic model outputs, with additional spatial
information from singular value decomposition providing insights into likely
physical mechanisms. The results demonstrate the importance of orbital
variation as an agent of change in climates of the past, and we demonstrate
that emulators derived from our modelling output can be used as rapid and
efficient surrogates of the full complexity model to provide estimates of
climate conditions from any set of forcing parameters.
The Fourth Lateran Council of 1215, the Prohibition against New Religious Orders, and Religious Women
Authors: Freeman Elizabeth 
Published: February 2018

Abstract
This article investigates canon 13 of the Fourth Lateran Council (1215), arguing that scholars have been too ready to interpret the canon as a prohibition against new religious orders. By examining the difference between religio and ordo, and by examining the broader context of reform movements within western Christendom in the long twelfth century, including Innocent III's actions as well as grassroots initiatives, this article notes that canon 13 did not ban new orders and that it was not as restrictive as it has been considered. While this article is not the first to note this, the implications of such a reassessment still deserve more scrutiny, including the implications for women in particular. A more flexible appreciation of the context of corporate religious life out of which canon 13 grew, and to which it contributed, helps us to understand better the religious lives of thirteenth-century women, including Beguines.

Abstract. Albeit high dependency on central government transfer (around 69% of total health expenditure), funding from local PAD has been increasing. The revenue shall support priority health programs. This study aims to analyze local health financing system and as input for health program planning. Health financing portrait how fund being spent, and identfying who the agents are as well as the beneficiaries. The study shows spending on health from local budget is Rp130,000. Expenditures on operational costs for direct activities and community-based health efforts or Upaya Kesehatan Masyarakat (UKM) are still low (41%). Puskesmas needs to do more health-related activities for babies and under-five children, and spending on under-five children activities were inexist. Performance-based budgeting at District Health Office (DHO) has not been implemented yet and poor performance of activities was due to very limited budget for conducting activities. Therefore, future planning for budgeting should consider (1) annual increase of locally derived revenue and excess fund or SILPA to improve financing of priority health programs; (2) local budget managed by DHO to be used for scaling up UKM and General Hospital uses funding managed by National Health Insurance Agency or Badan Penyelenggara Jaminan Sosial (BPJS) to provide quality personal care efforts or Upaya Kesehatan Perorangan (UKP), (3) financing of activities targeting babies and under-five children at Puskesmas should be improved; (4) one way of having performance-based budgeting at DHO is by full provision of operational costs for its direct activities.Keywords: local health financing, local government contribution, public health program (UKM), district
An Analysis of The National Health Insurance Policy Implementation in 2014 (Presidential Regulation No. 12 And 111/2013 on Health Insurance) from The Regulator’s Position

Abstract. JKN (National Health Insurance) is a government program that aims to provide health assurance for all Indonesian citizens for a healthy, productive, and prosperous life. In the two years after JKN was implemented, various problems occurred. This research used the qualitative approach with the Edward II implementation theory. Results of the research indicated that there were problems in communication, stemming from the lack of socialization and inharmonic regulations, there was also the problem of the lack of healthcare resources. From the disposition side, the policy makers often obstructs the implementation preparation, this is evident from the information on determining the premium size. From the organization structure, all the stakeholders have been well coordinated. We conclude that we are not ready to implement the JKN. We recommend that mass and effective socialization program to be performed using various methods of communication and involve the community. To reduce the disparity of healthcare services, we recommend that the regional government to establish various healthcare facilities to accelerate health development. There should also be regulations that allocates healthcare staff in every corner of the country to achieve Universal Health Coverage in 2019, as stated in the National Health Insurance Road Map.

Morphological Associative Memories
Authors: Valle Marcos Eduardo , Sussner Peter , Santos Alex S. 
Published: February 2018

AbstractMorphological associative memories (MAMs) belong to the class of morphological neural networks that – in contrast to classical models of artificial neural networks – employ operators of mathematical morphology in order to aggregate the synaptic weights and the incoming signal. The original and most widely known MAM model as well as some recent modifications of this model can be formulated using matrix operation of a lattice algebra called minimax algebra that is closely related to the umbra approach of grayscale mathematical morphology. Fuzzy MAM models execute basic operations of fuzzy mathematical morphology in the recall phase. In this article, we briefly review the aforementioned MAM models and discuss some applications in classification, hyperspectral image analysis, and prediction.
