Participación social de la juventud rural villaclareña en cooperativas agropecuarias: estudio de caso
Authors: Hernández Veitía Arianna B. , Moreira Echeverría Idalety 
Published: May 2019

A partir del año 2008 Cuba ha promovido la entrega de tierras en usufructo y ha incentivado la presencia de jóvenes en las comunidades rurales y en las actividades agropecuarias. La tenencia y la gestión de la tierra constituyen entre los jóvenes agropecuarios fuentes de tensión en la articulación de proyectos personales y sociales, en la construcción de identidades tradicionales —cercanas a lo local— o modernas, y median en la decisión de migrar o permanecer en el territorio. Este trabajo tiene como objetivo caracterizar la participación de los jóvenes rurales asociados a la Cooperativa de Créditos y Servicios (CCS) Jorge Montes perteneciente al municipio Cifuentes, en la provincia de Villa Clara. El análisis se centra en el protagonismo juvenil desde una perspectiva de equidad y justicia social a partir de reconocer sus potencialidades participativas. Villa Clara es una provincia con una marcada tendencia a disminuir su población juvenil resultado de procesos migratorios y de una baja natalidad. La investigación se apoya en la metodología de investigación–acción y aplica la triangulación de técnicas cualitativa (entrevistas a informantes claves, observación participante, y trabajo grupal con jóvenes cooperativistas) y cuantitativas (cuestionarios). Los resultados y las conclusiones ofrecen alternativas desde la participación responsable que permiten conocer intereses y motivaciones de los jóvenes a partir de las actividades que realizan en función de la forma organizativa de la producción agropecuaria a la que pertenecen. Las recomendaciones muestran la necesidad de reconocer la importancia de la participación social de los jóvenes en el sector agropecuario y su responsabilidad social.
Evidentials and (relayed) speech acts: hearsay as quotation
Authors: Korotkova Natasha 
Published: May 2019

This paper is devoted to what I will call quotative uses of hearsay evidentials, wherein they report a speech act made by a third party. Occasionally mentioned in the typological literature, quotative uses were first given a formal semantic account by Faller 2002 and have received little attention since. The goal of this paper is to put the spotlight on them. An ongoing debate in the literature is on the semantic status of evidentials and the place of evidentiality among other categories (see Matthewson 2012 and references therein). For Faller (2002, 2007), quotative uses are among the empirical tests that diagnose illocutionary evidentials, ones that deal with the structure of speech acts. In this paper, I re-implement Faller's original proposal within Krifka's (2014) framework that provides an explicit syntax-pragmatics interface. I then show that quotative readings may be the only argument, out of the currently provided in the literature, in favor of the existence of illocutionary evidentials. However, the status of such readings requires further research. I conclude by discussing quotative uses within a broader context of reported speech strategies.

Abstract
We present 0.″15 (1 kpc) resolution ALMA observations of the [C ii] 157.74 μm line and rest-frame 160 μm continuum emission in two z ∼ 3 dusty, star-forming galaxies—ALESS 49.1 and ALESS 57.1, combined with resolved CO (3–2) observations. In both sources, the [C ii] surface brightness distribution is dominated by a compact core ≤1 kpc in radius, a factor of 2–3 smaller than the extent of the CO (3–2) emission. In ALESS 49.1, we find an additional extended (8 kpc radius), low surface brightness [C ii] component. Based on an analysis of mock ALMA observations, the [C ii] and 160 μm continuum surface brightness distributions are inconsistent with a single-Gaussian surface brightness distribution with the same size as the CO (3–2) emission. The [C ii] rotation curves flatten at ≃2 kpc radius, suggesting that the kinematics of the central regions are dominated by a baryonic disk. Both galaxies exhibit a strong [C ii]/far-IR (FIR) deficit on 1 kpc scales, with FIR surface brightness to [C ii]/FIR slope steeper than in local star-forming galaxies. A comparison of the [C ii]/CO (3–2) observations with photodissociation region models suggests a strong far-UV (FUV) radiation field (G
0 ∼ 104) and high gas density (n(H) ∼ 104–105 cm−3) in the central regions of ALESS 49.1 and ALESS 57.1. The most direct interpretation of the pronounced [C ii]/FIR deficit is a thermal saturation of the C+ fine-structure levels at temperatures ≥500 K, driven by the strong FUV field.
The Limited Contribution of Low- and High-luminosity Gamma-Ray Bursts to Ultra-high-energy Cosmic Rays
Authors: Samuelsson Filip , Bégué Damien , Ryde Felix , Pe’er Asaf 
Published: May 2019

Abstract
The acceleration site for ultra-high-energy cosmic rays (UHECRs) is still an open question despite extended research. In this paper, we reconsider the prompt phase of gamma-ray bursts (GRBs) as a possible candidate for this acceleration and constrain the maximum proton energy in optically thin synchrotron and photospheric models, using properties of the prompt photon spectra. We find that neither of the models favors acceleration of protons to 1020 eV in high-luminosity bursts. We repeat the calculations for low-luminosity GRBs (llGRBs) considering both protons and completely stripped iron and find that the highest obtainable energies are <1019 eV and <1020 eV for protons and iron respectively, regardless of the model. We conclude therefore that for our fiducial parameters, GRBs, including low-luminosity bursts, contribute little to nothing to the UHECRs observed. We further constrain the conditions necessary for an association between UHECRs and llGRBs and find that iron can be accelerated to 1020 eV in photospheric models, given very efficient acceleration and/or a small fractional energy given to a small fraction of accelerated electrons. This will necessarily result in high prompt optical fluxes, and the detection of such a signal could therefore be an indication of successful UHECR acceleration at the source.
Probing the Emission Mechanism and Magnetic Field of Neutrino Blazars with Multiwavelength Polarization Signatures

Published: May 2019

Abstract
The characteristic two-component blazar spectral energy distribution (SED) can be of either leptonic and/or hadronic origins. The potential association of the high-energy neutrino event IceCube-170922A with the flaring blazar TXS 0506+056 indicates that hadronic processes may operate in a blazar jet. Despite multiwavelength follow-ups of the event and extensive theoretical modelings, the radiation mechanisms and the underlying magnetic field strength and configuration remain poorly understood. In this paper, we consider generic leptonic and hadronic blazar spectral models with distinct magnetic field strengths and radiation mechanisms. We analytically reproduce the SEDs and neutrino flux of hadronic models, and predict their X-ray to γ-ray polarization degrees. Furthermore, by performing relativistic magnetohydrodynamic simulations taking into account the polarization-dependent radiation transfer, we study the time-dependent multiwavelength polarization variability of the proton synchrotron (PS) model under a shock scenario. Our results suggest that the high-energy polarization degree and the neutrino flux can be jointly used to pinpoint the leptonic and/or hadronic blazar radiation mechanisms in the X-ray and γ-ray bands, and to infer the magnetic field strength in the emission region. In addition, the temporal multiwavelength polarization signatures in the PS shed light on the jet energy composition and the dynamical importance of magnetic fields in the blazar emission region. Future multiwavelength polarimetry facilities such as the Imaging X-ray Polarimetry Explorer and All-sky Medium Energy Gamma-ray Observatory together with neutrino telescopes such as IceCube can provide unprecedented observational constraints to probe the blazar radiation mechanisms and jet dynamics.
HST/COS Observations of the Warm Ionized Gaseous Halo of NGC 891

Published: May 2019

Abstract
The metallicity of galactic gaseous halos provides insights into accretion and feedback of galaxies. The nearby edge-on galaxy NGC 891 has a multicomponent gaseous halo and a background active galactic nucleus (AGN; LQAC 035+042 003) projected 5 kpc above the disk near the minor axis. Against the UV continuum of this AGN, we detect lines from 13 ions associated with NGC 891 in new Hubble Space Telescope/Cosmic Origin Spectrograph spectra. Most of the absorption is from the warm ionized gas with log T = 4.22 ± 0.04, log n
H = −1.26 ± 0.51, and log N
H = 20.81 ± 0.20. The metallicity of volatile elements (i.e., C, N, and S) is about half solar ([X/H] ≈ −0.3 ± 0.3), while Mg, Fe, and Ni show lower metallicities of [X/H] ≈ −0.9. The absorption system shows the depletion pattern seen for warm Galactic diffuse clouds, which is consistent with a mixture of ejected solar-metallicity disk gases and the hot X-ray-emitting halo (Z = 0.1–0.2 Z
⊙). The warm ionized gases are about five times more massive than the cold H i-emitting gases around the galactic center, which might lead to accretion with a mean rate of 102
M
⊙ yr−1 for a period of time. We also detect low-metallicity (≈0.1 Z
⊙) gases toward LQAC 035+042 003 at 110 km s−1 (a high-velocity cloud) and toward another sight line (3C 66A; 108 kpc projected from NGC 891) at 30 km s−1. This low-metallicity material could be the cold mode accretion from the intergalactic medium or the tidal disruption of satellites in the NGC 891 halo.

Abstract
We present the physical properties for 2281 northern eclipsing binary (EB) stars with eclipsing Algol (EA)-type light-curve (LC) morphology, based on data extracted from the Catalina Sky Survey (CSS). Our study is based on the analysis of the Eclipsing Binary via Artificial Intelligence (EBAI) artificial neural network (ANN) tool. An intensive search for the optimal ANN topology was performed. In order to feed the ANN with LCs that are representative of the CSS observations, two independent methods, based on template fitting and on the Two-Gaussian Model, were applied. As a result, five principal physical parameters were determined using only the CSS LCs, namely the temperature ratio,

; the sum of relative radii, ρ
2 + ρ
1;

;

; and

, where e is the eccentricity, ω is the argument of periastron, and i is the orbital inclination. Parameter uncertainties were estimated based on a Monte Carlo approach. When the ANN predictions were out of its training limits (1540 EBs), the parameters of the systems are based on the matching templates technique only. The results are fully in agreement with the expected parameter values for detached EB systems and can be used as initial inputs for advanced and dedicated EB models and/or for statistical purposes.

Published: May 2019

Depuis 2011, la poursuite du projet de recherche franco-québécois Fralubec sur l’évolution des multinationales Pechiney et Alcan au XX e siècle a été l’occasion pour une équipe de chercheurs de l’Université du Québec à Chicoutimi (UQAC) d’explorer l’évolution de cultures organisationnelles implantées dans les installations de la multinationale Alcan au Saguenay-Lac-Saint-Jean de 1967 jusqu’à son absorption par Rio Tinto en 2007. Pour couvrir ce patrimoine de quarante années de « façons de faire originales Alcan », l’enquête ainsi menée s’est appuyée sur des entretiens réalisés auprès de trente-neuf dirigeants patronaux et syndicaux, professionnels et chercheurs. Accompagnée de ces partenaires de recherche, l’équipe s’est investie dans un itinéraire de recherche qualitative pour recueillir, analyser et interpréter des données qualitatives permettant de créer un ou des modèles de cultures organisationnelles qui couvrent six domaines de gestion. Cet article présente des extraits de récits autobiographiques qui constituent un échantillon des résultats de cette étude exploratoire.

La conception managériale de la responsabilité sociale d’entreprise (RSE), une innovation sociale ? Enjeux d’une méthode d’évaluation systémique
Authors: Chanteau Jean-Pierre , Borrell Thomas , Temple Ludovic 
Published: May 2019

Le mouvement de la responsabilité sociale d’entreprise (RSE) qui gagne les pays du Sud est souvent présenté comme une innovation sociale permettant, par des initiatives volontaires modifiant le modèle productif ou la gouvernance d’une entreprise, de prendre en charge à son niveau les problèmes sociaux ou écologiques qu’engendre son activité. Cet article offre des éléments de méthode pour une évaluation complète, jusqu’au niveau sociétal, de ces dispositifs managériaux. Pour cela, l’institutionnalisme méthodologique IAD-SES est mobilisé : nous en exposons le cadre et nos apports à cette méthode. Puis nous présentons les résultats avec une étude des dispositifs RSE dans le secteur de la banane-export au Cameroun, prenant en compte les règles en usage et les double-effets pour évaluer leur impact sur la structuration du mode de gestion de la ressource foncière du territoire concerné. Ces résultats confirment que la RSE peut avoir un effet conservatoire plutôt qu’innovant sur la structure sociale.	Codes JEL : B52, M14, O13, O17, O35

Dans cet article nous proposons une cartographie du système national du financement de la recherche (SNFRI) français. Cette représentation s’appuie sur un modèle fonctionnel et organisationnel du système que nous faisons évoluer à travers l’ajout d’une fonction Évaluation. Cette dernière est conçue avec l’ambition de fournir une analyse de l’impact du système de recherche dans sa globalité plutôt qu’un examen qualitatif des projets et des acteurs qui le composent. Cette carte est enfin une attestation empirique de l’existence et de la pertinence de ces fonctions et constitue la première étape d’un travail plus large dont l’objectif final est de construire un modèle de SNFRI capable de l’évaluer et d’appréhender la dynamique évolutive globale du financement de la recherche en France.

Femmes dans l’armée Suisse
Authors: Monay Stéphanie 
Published: May 2019

Résumé Cet article s’intéresse à la socialisation politique des femmes engagées volontairement au sein de l’armée suisse, contexte où un service obligatoire masculin a cours. L’armée comme régime de genre instaure une structure spécifique de rapports de pouvoir et notamment de rapports sociaux de sexe. Nous verrons ici comment se caractérisent ce régime et ses normes de genre spécifiques et comment les femmes expérimentent une socialisation à la domination masculine en tant que « dominées ». En effet, insérées dans cet univers monosexué et hétéronormé, elles doivent faire face à un dispositif qui les dépeint comme des « inadaptées » voire même des « intruses ». À l’aide d’observations et d’entretiens, nous analyserons comment elles légitiment leur place dans les rangs militaires tout en intériorisant la domination globale des hommes sur les femmes.
Information Seeking Behavior of the Humanities and Social Science Undergraduates: A Case of University of Colombo
Authors: Wijetunge Pradeepa 
Published: May 2019

This paper discusses the Information Seeking Behavior (ISB) of the Humanities and Social Science (HSS) undergraduates of the University of Colombo with three objectives; to study the information resource usage of the undergraduates, to study the barriers they encounter in seeking and using the information and to study the information seeking process of the undergraduates. A questionnaire and Focus Group Meetings (FGMs) were used to gather quantitative and qualitative data. Convenient Sampling method was used and the response rate was 82% out of 550 questionnaires while 95 attended the FGMs. SPSS (ver. 22) and manual analysis were used to analyze data. Most respondents use Internet instead of library resources and do not use standard criteria to evaluate information. The majority consult their batch mates for help in using information resources. At the same time, most of them have not received any training in using the library resources or Internet. They face several barriers related to library resources, facilities, services and training which prevent them from reaching the library first for their information needs. The processes they follow to search and use information correspond to some other information seeking models. It is recommended that additional research is required to substantiate the gravity of this issue and librarians need to collaborate with the faculty to improve their ISB.

Abstract. Speciated atmospheric mercury including gaseous elemental mercury (GEM),
gaseous oxidized mercury (GOM), and particulate-bound mercury (PBM) were
measured continuously for a 1-year period at a suburban site, representing a
regional transport intersection zone, in east China. Annual mean
concentrations of GEM, PBM, and GOM reached 2.77 ng m−3,
60.8 pg m−3, and 82.1 pg m−3, respectively. GEM concentrations were
elevated in all the seasons except autumn. High mercury concentrations were
related to winds from the south, southwest, and north of the measurement
site. Combining analysis results from using various source apportionment
methods, it was found that GEM concentration was higher when quasi-local
sources dominated over long-range transport. Six source factors belonging to
the anthropogenic sources of GEM were identified, including the common
sectors previously identified (industrial and biomass burning, coal
combustion, iron and steel production, cement production, and incineration),
as well as an additional factor of shipping emissions (accounting for
19.5 % of the total), which was found to be important in east China where
marine vessel shipping activities are intense. Emissions of GEM from natural
surfaces were also found to be as important as those from anthropogenic
sources for GEM observed at this site. Concurrences of high GOM
concentrations with elevated O3 and temperature, along with the lagged
variations in GEM and GOM during daytime demonstrated that the very high GOM
concentrations were partially ascribed to intense in situ oxidation of GEM.
Strong gas–particle partitioning was also identified when PM2.5 was
above a threshold value, in which case GOM decreased with increasing PM2.5.
An analysis of the activity in the Polish internet sphere from the angle of social mobilization to perform acts of violence. A case study of the immigrant crisis
Authors: Ożarowska Danuta Bożena 
Published: May 2019

This article is a case study of the process of mobilization to violence on the internet. The goal of this paper was to identify a select number of factors within the narrative on the topic of modern immigration that can be found on the internet and analyze them using the theoretical constructs that can be found in the literature on this subject.
The scientists that study genocide have identified several factors commonly found in historically documented events that must be present in order for genocide to occur. In this paper the author will refer to works of scientists such as Helen Fein, Manus I. Midlarsky, Lech M. Nijakowski.
The author of the paper analyzed the content published on the internet that deals with the topic of immigration. The materials selected for research contained topics that treat the subject of accepting refugees from outside of Europe, their process of assimilation and the way they coexist with the local population. The analysis was based on content in the Polish language which includes both materials that were created in Polish and those that were originally in a different language and then were remade with Polish footnotes. The content for the study was selected from among the following sources: propaganda movies which spread on the internet through social media, short unscientific propaganda and informational articles and finally memes (pictures with short footnotes).
Factors that were analyzed in the following article:
1)	Universe of obligation, construct created by Helen Fein.
2)	Conspiratory discourse, described by Lech Nijakowski.
3)	Utility and parasitism; discourse referring to them.
4)	Two conditions necessary to instigate genocide, described by Manus I. Midlarsky.
5)	Discourse on the topic of immoral sexual actions described by the author based on the theory of discourses created by Lech Nijakowski.
During the study all the aforementioned factors have been identified. The author described the examples analyzed, interpreted them and subsequently matched them to the categories described above. It was determined that within those examples we can distinguish a number of factors that match the elements of mobilizing the population to violence. The article closes with an analysis of potential consequences of the phenomena described.
