Abstract
We report the discovery of KMT-2018-BLG-1292Lb, a super-Jovian M
planet = 5.0 ± 1.2 M

J
planet orbiting an F or G dwarf M
host = 1.2 ± 0.3 M
⊙, which lies physically within

of the Galactic plane. The source star is a heavily extincted A

I
∼ 5.2 luminous giant that has the lowest Galactic latitude, b = −0.°28, of any planetary microlensing event. The relatively blue blended light is almost certainly either the host or its binary companion, with the first explanation being substantially more likely. This blend dominates the light at the I band and completely dominates at the R and V bands. Hence, the lens system can be probed by follow-up observations immediately, i.e., long before the lens system and the source separate due to their relative proper motion. The system is well characterized despite the low cadence, Γ = 0.15–0.20 hr−1, of observations and short viewing windows near the end of the bulge season. This suggests that optical microlensing planet searches can be extended to the Galactic plane at relatively modest cost.

Abstract
Blue stragglers (BSs) are stars located in an unexpected region of the color–magnitude diagram (CMD) of a stellar population, as they appear bluer and more luminous than the stars in the turn-off region. They are ubiquitous, since they have been found among Milky Way field stars, in open and globular clusters, and also in other galaxies of the Local Group. Here we present a study on the BS population of the old and metal-rich open cluster Collinder 261, based on Gaia DR2 data and on a multi-epoch radial velocity survey conducted with Fibre Large Array Multi Element Spectrograph (FLAMES) at the Very Large Telescope (VLT). We also analyze the radial distribution of the BS population to probe the dynamical status of the cluster. BS candidates were identified first with Gaia DR2, according to their position on the CMD, proper motions, and parallaxes. Their radial distribution was compared with those of main sequence, red giant, and red clump stars, to evaluate mass segregation. Additionally, their radial velocities (and the associated uncertainties) were compared with the mean radial velocity and velocity dispersion of the cluster. When possible, close binaries and long-period binaries were also identified, based on the radial velocity variations for the different epochs. We also looked for yellow stragglers, i.e., possible evolved BSs. We found 53 BS members of Collinder 261, six of them were already identified in previous catalogs. Among the BS candidates with radial velocity measurements, we found one long-period binary, five close-binary systems, three nonvariable stars; we also identified one yellow straggler.
Victims and perpetrators of feminicide in the language of the Mexican written press
Authors: Tiscareño-García Elizabeth , Miranda-Villanueva Oscar-Mario 
Published: January 2020

This study investigates the language used by national newspapers in Mexico: “El Universal”, “La Jornada”, “Milenio”, and “Reforma”, when addressing the issue of feminicide regarding victims and perpetrators, as well as their relationship with the gender of the reporter and with each newspaper. The research is based on the analysis of qualitative content and the theoretical framework of framing. Categories were built on the type of language in cases of feminicide of 360 journalistic texts published during 2017: 1) Narrative of feminicide; 2) Justification of the perpetrator or alleged perpetrator; 3) Social issues; 4) Blaming the victim. The analysis yielded cases of victim blaming to a lesser extent than those of the perpetrator's justification. Aspects of the narration of feminicide stood out both by the gender of the reporter and by the media in the four newspapers, from two perspectives: 1) The fact, the follow-up, or the context; 2) The fact, legal aspects, and statistics. Reporters, men and women, tend to justify the perpetrator; male reporters blame the victim more than female reporters; and female reporters contextualize feminicide through social issues: social violence, impunity, and failures in legal processes. “La Jornada” is inclined towards social issues, while “El Universal” tends to justify the perpetrator.
En este estudio se investiga el lenguaje que utilizan los periódicos de tirada nacional en México: «El Universal», «La Jornada», «Milenio» y «Reforma», al momento de abordar el tema del feminicidio con respecto a víctimas y victimarios o presuntos victimarios, así como su relación con el género del reportero y con cada periódico. La investigación se apoya en el análisis de contenido cualitativo, y el marco teórico-conceptual del «framing». Se construyeron categorías sobre el tipo de lenguaje en casos de feminicidios de 360 textos periodísticos publicados durante 2017: 1) Narrativa del feminicidio; 2) Justificación del victimario o presunto victimario; 3) Problemática social; 4) Culpabilización de la víctima. El análisis arrojó casos de culpabilización de la víctima en menor proporción que los de la justificación del victimario. Sobresalieron aspectos de la narración del feminicidio tanto por el género del reportero como por el medio en los cuatro periódicos, desde dos perspectivas: 1) El hecho, el seguimiento o el contexto; 2) El hecho, los aspectos legales y la estadística. Reportero y reportera tienden a justificar al victimario; el reportero culpabiliza más a la víctima que la reportera; y la reportera contextualiza más el feminicidio a través de la problemática social: violencia social, impunidad y fallas en los procesos legales. «La Jornada» se inclina por la problemática social, mientras que «El Universal» tiende a la justificación del victimario.

Published: January 2020

The constant struggle to attract new readers has led the digital news media to adopt search engine positioning strategies within their newsrooms. Given that readers are increasingly opting to consume their news via search engines, such as Google or Bing, this study explores perceptions and applications of search engine optimization (SEO) in the online news media and identifies the future training needs of journalists in this sector. To do so, 33 semi-structured interviews were conducted with individuals representative of three professional profiles: professional journalists, SEO consultants, and academics. Based on the data collected, we created five semantic categories – with 25 subcategories – and we correlated the perceptions of the SEO experts employed by the news media with those of the academics. The results highlight varying degrees of convergence and divergence in perceptions across these three professional profiles. Similarly, the results confirm the sector’s pressing need to attract readers by implementing search engine positioning techniques and, hence, its need to ensure future journalists are well trained in technical SEO, on-page SEO, off-page SEO, in the use of SEO analytics and audit tools, and in the ability to identify search trends so that they have the necessary skills to win the struggle for more readers.
La lucha de los cibermedios para atraer nuevos lectores ha motivado el uso de estrategias de posicionamiento en buscadores en el seno de las redacciones periodísticas. Dado el consumo, cada vez más frecuente, de noticias a través de buscadores como Google o Bing, este trabajo explora la percepción y la aplicación de la optimización en buscadores (SEO) en los medios de comunicación online y determina las diferentes necesidades formativas de los futuros periodistas que quieran trabajar en este campo. Para ello, se realizaron 33 entrevistas semi-estructuradas a personas que representan tres perfiles profesionales diferentes: periodistas profesionales, consultores de SEO y profesores universitarios. A través de los datos recogidos, creamos cinco categorías semánticas –con 25 subcategorías– y correlacionamos las percepciones de los expertos en SEO que trabajan en empresas periodísticas con las percepciones de los profesores en el contexto académico. Los resultados confirman los diferentes grados de convergencia y divergencia entre estos tres perfiles profesionales. Asimismo, se reafirma la creciente necesidad de atraer lectores a través de técnicas de posicionamiento en buscadores, por lo que señalamos la necesidad de formar a los futuros periodistas en SEO técnico; en SEO On Page; en SEO Off Page; en herramienta analítica; en auditoría SEO; y en la capacidad de identificar tendencias de búsqueda para que estén cualificados con las competencias necesarias para afrontar la lucha por los públicos.
La démocratie numérique au défi de la critique sociale en France
Authors: Mabi Clément 
Published: January 2020

Cet article fait le pari que le mouvement des gilets jaunes et le Grand débat national constituent un bon laboratoire pour analyser la capacité du numérique à équiper la critique sociale. Il tente de saisir les évolutions de l’expression critique des citoyens en contexte numérique en replaçant le mouvement dans une dynamique plus large, celle du développement d’une « démocratie numérique » en France, où l’influence des technologies interroge le fonctionnement de notre démocratie et la place qu’y occupent les citoyens. Dans ce cadre, nous verrons que les nouvelles formes d’expression citoyenne permises par le numérique mettent en tension la démocratie, qu’elle soit représentative ou participative, avec une forme de démocratie du public, où l’opinion publique prétend installer une relation directe entre gouvernants et gouvernés. Qu’est-ce que ce poids renouvelé de l’opinion fait à l’expression de la critique sociale ? Comment les formes de participations plus institutionnelles peuvent-elles parvenir à offrir un débouché politique à l’expression critique lorsque cette dernière trouve sur le Web des espaces de visibilité alternatifs ?
Une revue catholique d’Égypte à l’époque nassérienne
Authors: Mayeur-Jaouen Catherine 
Published: January 2020

Après une brève présentation des revues et journaux catholiques égyptiens du xxe siècle qui peuvent servir de sources, l’article est consacré à la plus remarquable et la plus originale de ces revues, Ḥaqlunā(1949‑1970). Elle fut lancée par l’avocat Pierre Cassab (Buṭrus Kassāb, 1913‑1986) pour servir à l’Association de la Jeunesse catholique d’Égypte, fondée en 1947. Donnant des nouvelles de l’Église catholique dans le monde, Ḥaqlunā militait pour le nécessaire rôle des laïcs dans des associations et dans l’Église. Source précieuse pour la diffusion et la réception du Concile Vatican II (1962‑1965) en Égypte, la revue – d’abord animée par des « Syriens d’Égypte » de rite grec‑catholique, comme Pierre Cassab, ou maronite, comme Michel Farah (Mīšīl Faraḥ) – est particulièrement attentive à la vie des Églises orientales et à l’affirmation des coptes-catholiques comme Église nationale d’Égypte. Vis‑à‑vis des coptes‑orthodoxes, Ḥaqlunā, dans un esprit œcuménique, applaudit le Renouveau entamé sous Cyrille VI. Quant à l’islam, tout en soutenant fidèlement les orientations conciliaires manifestées dans Nostra Aetate, Ḥaqlunā rend allusivement compte des inquiétudes des catholiques égyptiens face à l’islamisation de l’État nassérien. La question féminine enfin, d’abord quasi‑absente, prend de l’importance dans les années 1960.
Les ʿammē « en Ǧazīra et en Occident ». Genèse et fixation d’un ethnonyme standardisé pour les tribus arabes chrétiennes
Authors: Pierre Simon 
Published: January 2020

Lorsque la littérature syro‑occidentale désigne des Arabes chrétiens (ṭayyōyē krisṭyōnē), elle emploie souvent une expression ternaire à l’ordre variable : « les Tanūkōyē, ʿAqūlōyē et Ṭūʿōyē ». Ces populations (ʿammē) ont joué un rôle important lors de la IIe guerre civile (60‑72/680-692) au sein de l’Église syro‑orthodoxe alors que celle-ci commence à envisager l’altérité musulmane. C’est à ce moment qu’un évêché homonyme est attesté, notamment sous l’autorité de Georges (m. 105/724), un des principaux intellectuels de son temps. Ces peuples semblent avoir résidé en « Occident » (le ǧund de Qinnasrīn en formation) et dans la partie post-romaine de la Haute-Mésopotamie (la Ǧazīra) à l’époque omeyyade. Si les Tanūḫ (Tanūkōyē) sont bien identifiés comme une collectivité irakienne partiellement installée en Syrie du Nord, la période de cette migration, traditionnellement placée à l’époque proto‑byzantine, reste indéterminée. Les deux autres termes sont plus obscurs : les ʿAqūlōyē se rapportent aux habitants du ressort d’al‑Kūfa, l’expression étant presque assurément post-hégirienne, tandis que les Ṭūʿōyē correspondraient à d’ancien groupes de la même région. Nous faisons l’hypothèse que le déplacement de ces ʿammē irakiens désignés par cet ethnonyme ternaire standardisé (qui ne sont pas des tribus au sens du nasab arabe) vers l’espace syrien découle d’une politique de transferts sous le califat de Muʿāwiya (m. 60/680). C’est sans doute dans ce contexte qu’ils auraient été affiliés à la nomenclature épiscopale miaphysite, à une époque où il était possible de participer au mouvement des croyants tout en s’intégrant à l’Église d’Antioche.
CXCR4s in Teleosts: Two Paralogous Chemokine Receptors and Their Roles in Hematopoietic Stem/Progenitor Cell Homeostasis

Published: January 2020

AbstractHematopoietic stem/progenitor cells (HSPCs) generate the entire repertoire of immune cells in vertebrates and play a crucial role during infection. Although two copies of CXC motif chemokine receptor 4 (CXCR4) genes are generally identified in teleosts, the function of teleost CXCR4 genes in HSPCs is less known. In this study, we identified two CXCR4 genes from a teleost, ayu (Plecoglossus altivelis), named PaCXCR4a and PaCXCR4b. PaCXCR4b was constitutively expressed in ayu HSPCs, whereas PaCXCR4a was induced by LPS treatment. The stromal-derived factor-1–binding activity of CXCR4b was significantly higher than that of CXCR4a, whereas the LPS-binding activity of CXCR4a was significantly higher than that of CXCR4b in the teleosts ayu, large yellow croaker (Larimichthys crocea), and tiger puffer (Takifugu rubripes). CXCR4a+ HSPCs were mobilized into blood by LPS, whereas CXCR4b+ HSPCs were mobilized by leukocyte cell–derived chemotaxin-2. PaSDF-1 and PaCXCR4b, but not PaCXCR4a, inhibited HSPC proliferation by regulating reactive oxygen species levels. Compared with PaCXCR4b+ HSPCs, PaCXCR4a+ HSPCs preferentially differentiated into myeloid cells in ayu by maintaining high stem cell leukemia expression. These data suggest that the two copies of CXCR4s achieve a division of labor in the regulation of teleost HSPC homeostasis, supporting the concept that subfunctionalization after gene duplication in teleosts may stabilize the immune system.
Photoacoustic measurement with infrared band-pass filters significantly overestimates NH3 emissions from cattle houses due to volatile organic compound (VOC) interferences

Published: January 2020

Abstract. Infrared (IR) photoacoustic spectroscopy (PAS) using band-pass
filters is a widely used method for measurement of NH3 and
greenhouse gas emissions (CH4, N2O and CO2) especially in
agriculture, but non-targeted gases such as volatile organic compounds
(VOCs) from cattle barns may interfere with target gases, causing inaccurate
results. This study made an estimation of NH3 interference in PAS
caused by selected non-targeted VOCs which were simultaneously measured by a
PAS and a PTR-MS (proton-transfer-reaction mass spectrometry). Laboratory
calibrations were performed for NH3 measurement, and VOCs were selected
based on a headspace test of the feeding material (maize silage). Strong
interferences of VOCs were observed on NH3 and greenhouse emissions
measured by PAS. Particularly, ethanol, methanol, 1-butanol, 1-propanol and
acetic acid were found to have the highest interferences on NH3, giving
empirical relationships in the range of 0.7 to 3.3 ppmv NH3 per ppmv VOC. A linear response was typically obtained, except for a nonlinear
relation for VOCs on N2O concentration. The corrected online NH3
concentrations measured by PAS in a dairy farm (with empirical relationships
2.1±0.8 and 2.9±1.9 for Location 1 and Location 2,
respectively) were confirmed to be correlated (R2=0.73 and 0.79) to
the NH3 concentration measured simultaneously by the PTR-MS when the
empirical corrections obtained from single VOC tests were applied.
Current, steady-state and historical weathering rates of base cations at two forest sites in northern and southern Sweden: a comparison of three methods
Authors: Casetou-Gustafson Sophie , Grip Harald , Hillier Stephen , Linder Sune , Olsson Bengt A. , Simonsson Magnus , Stendahl Johan 
Published: January 2020

Abstract. Reliable and accurate methods for estimating soil mineral weathering rates
are required tools in evaluating the sustainability of increased harvesting
of forest biomass and assessments of critical loads of acidity. A variety of
methods that differ in concept, temporal and spatial scale, and data
requirements are available for measuring weathering rates. In this study,
causes of discrepancies in weathering rates between methods were analysed
and were classified as being either conceptual (inevitable) or random. The
release rates of base cations (BCs; Ca, Mg, K, Na) by weathering were
estimated in podzolised glacial tills at two experimental forest sites, Asa
and Flakaliden, in southern and northern Sweden, respectively. Three
different methods were used: (i) historical weathering since deglaciation
estimated by the depletion method, using Zr as the assumed inert reference; (ii) steady-state weathering rate estimated with the PROFILE model, based on
quantitative analysis of soil mineralogy; and (iii) BC budget at stand
scale, using measured deposition, leaching and changes in base cation stocks
in biomass and soil over a period of 12 years. In the 0–50 cm soil horizon
historical weathering of BCs was 10.6 and 34.1 mmolc m−2 yr−1, at Asa and Flakaliden, respectively. Corresponding values of
PROFILE weathering rates were 37.1 and 42.7 mmolc m−2 yr−1.
The PROFILE results indicated that steady-state weathering rate
increased with soil depth as a function of exposed mineral surface area,
reaching a maximum rate at 80 cm (Asa) and 60 cm (Flakaliden). In contrast,
the depletion method indicated that the largest postglacial losses were in
upper soil horizons, particularly at Flakaliden. With the exception of Mg and Ca in shallow soil horizons, PROFILE produced
higher weathering rates than the depletion method, particularly of K and Na
in deeper soil horizons. The lower weathering rates of the depletion method
were partly explained by natural and anthropogenic variability in Zr
gradients. The base cation budget approach produced significantly higher
weathering rates of BCs, 134.6 mmolc m−2 yr−1 at Asa and
73.2 mmolc m−2 yr−1 at Flakaliden, due to high rates
estimated for the nutrient elements Ca, Mg and K, whereas weathering rates
were lower and similar to those for the depletion method (6.6 and 2.2 mmolc m−2 yr−1 at Asa and Flakaliden). The large discrepancy in
weathering rates for Ca, Mg and K between the base cation budget approach
and the other methods suggests additional sources for tree uptake in the soil
not captured by measurements.
Prevalencia y factores asociados a incontinencia urinaria en el área de salud este de Valladolid
Authors: Martín Tuda Cristina , Carnero Fernández Maria Pilar 
Published: January 2020

Introducción: La incontinencia urinaria (IU) es la pérdida involuntaria de orina que constituye un problema social o higiénico importante y es demostrable de forma objetiva. Es un síntoma común que aparece en muchas enfermedades, afectando a todos los grupos de edad y a ambos sexos. En España se estima una prevalencia global de 24% en la mujer y 7% en el hombre, aumentando con la edad hasta el 50% y 29% respectivamente. A pesar de su repercusión en la calidad de vida se encuentra infradiagnosticada por diversos motivos. Objetivo: Determinar la prevalencia de la IU y sus factores asociados. Material y Método: En este estudio epidemiológico observacional retrospectivo se recogieron datos de las historias clínicas de pacientes con IU de la Unidad de Suelo Pélvico del Área de Salud Este de Valladolid. Resultados: Los tipos de incontinencia más frecuentes fueron: de esfuerzo (43,13%) y mixta (39,21%). Los factores de riesgo y patología asociada más importantes fueron episiotomía (57,1%) y cistocele (32,6%) en las mujeres y adenocarcinoma de próstata (60%) en los hombres. Tras tratamiento rehabilitador en un intervalo de 2 a 3 meses mejoraron las respuestas en los cuestionarios de incontinencia urinaria (ICIQ-SF).Conclusiones: Los datos recopilados están en consonancia con estudios revisados, y viendo los avances en prevención y tratamiento de IU resulta coherente su abordaje multidisciplinar.
Introduction: Urinary incontinence (UI) is the involuntary loss of urine that is a major social or hygienic problem and is objectively provable. It is a common symptom that appears in many diseases, affecting all age groups and both sexes. In Spain it is estimated a prevalence of 24% in women and 7% in men, increasing with age up to 50% and 29% respectively. Despite its impact on quality of life, it is under-diagnosed for various reasons. Objective: To determine the prevalence of UI and its associated factors. Material and method: In this retrospective longitudinal epidemiological study data were collected from the medical histories of patients with UI belonging to the Pelvic Floor Unit of the East Health Area in Valladolid. Results: The most frequent types of incontinence were: effort (43,13%) and mixed (39,21%). The most important risk factors and associated diseases were episiotomy (57.1%) and cystocele (32.6%) in women and adenocarcinoma of prostate (60%) in men. Responses in the questionnaires of urinary incontinence (ICIQ-SF) improved after 2-3 months of rehabilitation treatment.Conclusions: The collected data are consistent with studies reviewed, and seeing the progress in prevention and treatment of UI, multidisciplinary approach is coherent.
