Standardizacija – jedinstvena spona za cijeli svijet = Standardization - Unique Bond for the Whole World
Authors: Filatov Nataša
Published: February 2022

Nema sumnje da bez standardizacije ljudsko društvo, kakvog ga danas poznajemo, ne bi moglo ni poslovati ni funkcionisati. Ipak, standardizacija nije karakteristika samo današnjice jer standardi postoje i upotrebljavaju se već hiljadama godina. Stoga možemo zaključiti da se standardizacija razvijala i napredovala paralelno sa razvo-jem i napretkom čovječanstva.Svrha članka je da čitaoce ukratko provede kroz istoriju standardizacije i da ih pobliže upozna sa pojmovima „standardizacija“ i „standard kao važnim elementima organizovanog razvoja svakog modernog društva. U član-ku se pokušalo odgovoriti na sljedeća pitanja: Šta je standardizacija?; Koje su koristi od nje?; Koji su njeni opći ciljevi?; Na kojim principima se zasniva današnja standardizacija?; Koji nivoi postoje u standardizaciji?; Šta je tijelo za standardizaciju?; Šta je standard?; Koje su njegove karakteristike?; Koje vrste standarda imamo? = There is no doubt that without standardization human society as we know today, could not operate nor work. However, standardization is not only the characteristic of today because standards exist and are used for thousands of years. Therefore, we can conclude that the standardization developed and progressed in parallel with the development and progress of mankind. The purpose of this article is to guide the reader briefly through the history of standardization and to acquaint closely with the concepts of “standardization” and “standard as important elements of organized development in any modern society. This article attempts to answer the following questions: What is the standardization? What are the benefits the standardization? What are its general objectives? On what principles are based today’s standardization? What levels exist in the standardization? What is the standardization body? What is the standard? What are its characteristics? What kind of standards we have?

CALIBRATION AND INJECTION RATE SHAPING APPROACHES USING 1D HYDRAULIC DIESEL INJECTOR MODELING FOR GASOLINE COMPRESSION IGNITION APPLICATIONS
Authors:   , Desai Atharva
Published: February 2022

The gasoline compression ignition (GCI) works on the principle of harnessing the benefits of light distillates in a compression ignition (CI) engine. Recent research has shown that along with air management and after-treatment systems; fuel systems also play a vital role in enabling GCI technology. The injector in the fuel injection system (FIS) is a key component driving the efficiency of the combustion phenomena. Subsequently, injection strategies, characteristics, and overall injection quality influence the combustion process and controls certain metrics like fuel consumption, pollutant emissions, and combustion noise. In this work, a one-dimensional (1-D) model of a heavy-duty diesel injector employed in Cummins ISX15 Engine, built in a commercially available computer software called Gamma Technologies (GT)-SUITE, was studied, and analyzed. This work focuses on developing a generalized methodology from previous work to adapt this injector with gasoline-like fuels by recalibrating the discharge coefficients using in-built GT-SUITE optimization techniques. Post recalibration, the 1-D model closely reproduces experimentally measured injection performance characteristics like rate of injection (ROI) profiles, injected quantities, hydraulic delays, and needle lift profiles for the heavy-duty, high-pressure diesel injector using gasoline-like fuels across engine operating points of interest, thereby enabling GCI. As the previous study has demonstrated the potential of injection rate shaping in the mitigation of oxides of nitrogen (NOx) emissions, this validated 1-D model was further used to investigate various injector geometries to produce custom injection rate shapes. Finally, an optimization methodology was developed to generate rate shape of interest to obtain a single set of the selected dimensional parameters across high-efficiency engine operating points using the in-built GT-SUITE optimization techniques. Furthermore, a full factorial design of experiments (DoE) using the candidate injector geometries, hydraulic components were simulated and post-processed to obtain an optimal rate shape, thereby acting as a validation tool for the optimal rate shape obtained using GT-Suite’s optimization methods.

In this paper, using the finite element method, a comparative study on bending schemes of standard titanium perforated reconstruction plates used in the reconstruction of mandibular defects is presented. Currently, there is a need for equipment for high-precision bending of perforated plates, with the purpose of сreating a specific geometry that follows the natural curvature of the patient's jaw. The personalization of the implant allows to restore the natural symmetry of the patient's face and, therefore, accelerate the process of his social reintegration. The article compares six bending schemes corresponding to different bending directions, angles and levers. The results obtained allow to understand the specificities of the process, evaluate its strain characteristics and elastic springback after bending, which are necessary for the development of equipment for bending personalized implants.

Due to the growing global crisis against the background of the COVID-19 pandemic, the issue of uninterrupted provision of medicines to the population has become critically important. In this regard, the introduction of information management systems at pharmaceutical enterprises is becoming particularly relevant. The pharmaceutical industry as a whole faces a number of unique challenges, including close regulatory oversight, sophisticated testing methods, and growing financial pressures as competition in the market increases. Industry leaders are digitizing core functions within their internal vertical operational processes, as well as with their value chain partners. One of the information management systems in the laboratory is the LIMS (Laboratory information system) information system. One of the challenges when choosing LIMS in pharmaceuticals is the variety of laboratories in the company - combinatorial chemistry, screening, preclinical and clinical bioanalysis, analytical chemistry, industrial R&D and production quality control, requiring unique needs and workflows. With the development of business, information technology and the regulatory framework, the role of LIMS in the pharmaceutical organization is also increasing. Proper implementation of this mechanism in the work of a pharmaceutical enterprise will help to preserve the quality of the product, reduce and optimize the work and satisfy the end user and government agencies.

Micro-credentials: Surveying the landscape.
Authors: Cowie Neil , Sakui Keiko
Published: February 2022

This paper will discuss micro-credentials (MCs) as a viable emerging form of non-degree qualification which offers flexible, inexpensive contents that closely match learner needs. The opportunities to gain MCs, including language learning, are increasing with higher education institutions and other providers rapidly developing a variety of online MCs. However, the lack of agreed definitions as to what MCs are can undermine their value and uptake. MCs also vary widely in terms of duration, assessment, and whether they can lead to further qualifications or not. In order to overcome these challenges governments are establishing various frameworks for MCs. The EU, New Zealand, Malaysia and the U.S. have all created good practice models to guide both providers and learners. Some of the common features that these agencies have specified in the development of these frameworks will be explained. In addition, the current provision and uptake of MCs in Japan will be described and suggestions made as to how this could develop in the future, especially concerning the role of higher education institutions.
Transitions, bridges and connections: student reflections on the role of SNS in ERTL in 2020.
Authors: Healy Sandra
Published: February 2022

The COVID-19 pandemic of 2020 transformed the educational spaces and lives of teachers and students worldwide. Students entering Japanese universities in 2020 were particularly affected by this, moving from high school to university during this period, and therefore facing multiple challenges. As part of a larger project exploring how the move to online learning affected them, the participants in this study were asked to reflect on their experiences of emergency remote teaching and learning (ERTL) in 3-minute videos they created and uploaded to the university learning management system (LMS). This paper focuses on one significant theme that proved pivotal during this transition – the use of social network systems (SNS) to bridge the move between school and university. It was found that SNS provided vital support during this time of physical distancing and contributed to student well-being. Students were able to create relationships with their peers through SNS and construct social capital in their new community while maintaining previous relationships and existing social capital.
A comparison of linear and interactive fiction on vocabulary acquisition, reading comprehension and engagement.
Authors: Nagai Tsuzuki , York James
Published: February 2022

There are few studies that explore the cognitive and affective benefits of interactive fiction(IF) in language learning and teaching contexts. Inspired by Neville, et al. (2009), we compared the effectiveness of IF in comparison to non-interactive, linear fiction in terms of vocabulary acquisition, reading comprehension and motivation in a university EFL context. Participants (n = 88) were divided into two groups. The control group read a linear story; the experimental group played through an interactive version of the same story. A pre- and post-experiment vocabulary test was employed to measure the acquisition of 16 target vocabulary words. A test based on the actions of characters within the story was also employed to measure reading comprehension. Finally, a post-test questionnaire measured student perceptions of learning with linear and IF.
This paper introduces the results of the study which are as follows. Findings revealed no significant difference in scores between the control (linear) and experimental (IF) groups for vocabulary acquisition or reading comprehension. However, an additional analysis of the data was conducted based on learners’ gaming proficiency which revealed that, in comparison to high proficiency gamers, low proficiency gamers found it difficult to control the interactive version of the story. This suggests that students’ level of game literacy may influence perceptions of the system.

Wie und warum der Kitt gekaut wird
Authors: Varga Krisztina
Published: February 2022

Der Roman von Ferenc Molnár, einem der bedeutendsten ungarischen Schriftsteller und Journalisten, „A Pál utcai fiúk“ erschien erstmals 1906 und gehört seitdem zu den meistgelesenen und beliebtesten Romanen in Ungarn. Da das Werk in der Grundschule als Pflichtlektüre gilt, sind die Schüler mit den zur Jahrhundertwende verwendeten Wörtern wie grund, einstand und gittegylet vertraut, wobei die Begriffe gittegylet sowie rágja a gittet, die den Untersuchungsgegenstand dieser Arbeit bilden, auch heute noch verwendet werden, allerdings nicht mehr im wortwörtlichen, sondern eher im übertragenen Sinn.

Das Buch wurde mit großem Erfolg in zahlreiche Sprachen übersetzt (und siebenmal verfilmt). Bei der Übersetzung gab es bestimmte Umstände, die unbedingt zu beachten waren, so auch die Tatsache, dass sich die Bedeutung der beiden Begriffe seither auch im Ungarischen verändert hat. Da das Wort Kitt im Deutschen neben der wortwörtlichen Bedeutung auch in ihrer abstrakten Bedeutung verwendet wird, bedarf es glücklicherweise nicht allzu viel Erklärung für die zielsprachlichen Leser. Der Beitrag setzt sich zum Ziel, einerseits die kulturelle Einbettung zweier kulturspezifischer Elemente in der Ausgangssprache darzustellen, andererseits die Möglichkeiten zu untersuchen, auf welche Weise diese kulturelle Einbettung den Lesern der Zielsprache nahegebracht werden kann.

Influencia del ambiente de trabajo sobre el empoderamiento y sobre la infusión del sistema de información
Authors: Un Jan Alberto , Cauvi Gabriela
Published: February 2022

Las empresas invierten altos montos de dinero en la implementación de sistemas y tecnologías de información, según Gartner3, pero no aprovechan todo su potencial porque los sistemas recientemente implementados no llegan al punto de infusión, conforme señalaron Kim y Gupta6. La infusión es el uso del sistema en su completo potencial, de manera extendida, integrativa y emergente. Este artículo utiliza el instrumento propuesto por Kim y Gupta6 para medir la influencia del ambiente de trabajo sobre el empoderamiento, y la influencia del empoderamiento sobre la infusión de sistemas de información. Se obtiene así un mecanismo para lograr la exitosa infusión de los sistemas de información. Los datos para validar las hipótesis fueron recolectados por medio de una encuesta a usuarios de diferentes sistemas de información. Todos los usuarios son estudiantes de la maestría en Gestión de la Universidad Nacional Mayor de San Marcos, semestres 2015-2 y 2016-1, que laboran en empresas de la ciudad de Lima. En el modelo resultante, el ajuste percibido es la variable del ambiente de trabajo que inicia el empoderamiento; se debe trabajar sobre el diseño del sistema de información para lograr que este se ajuste y coincida con el trabajo del usuario. Esta coincidencia logrará el empoderamiento, y el empoderamiento permitirá el uso integrativo y extendido del sistema de información. Esto hará posible el uso emergente del sistema de información, para completar su infusión. Se concluye que al mejorar el ajuste percibido se mejora la infusión.

Crop Diversification for Sustainable Agriculture
Authors: Paroda Raj
Published: February 2022

In India, over the years, the new cropping systems have become predominant in view of their higher productivity as well as income for farmers. Examples are rice-wheat cropping system in the north, groundnut in Gujarat, sugarcane in the north, chickpea in southern states, arhar in the north-western states, soybean in Madhya Pradesh and adjoining states, and winter maize in Bihar. Unfortunately, most of these systems require diversification for greater sustainability and conservation of natural resources. Time is ripe now to bring in needed reforms in the existing cropping systems that are more scientifically based and more suited to varying agro-climatic conditions. The possibilities of future crop diversification that can increase farmers’ production as well as income and also ensure conservation agriculture through sustainable intensification are described in this commentary. There is a need for long term planning and development of various strategies for crop diversification in the best national interest.
ExoVista: A Suite of Planetary System Models for Exoplanet Studies
Authors: Stark Christopher C.
Published: February 2022

Studies of future space- and ground-based exoplanet surveys often rely on models of planetary systems to simulate instrument response, estimate scientific yields, perform trade analyses, and study efficient observation strategies. Until now, no planetary system models contained all of the basic physics necessary to enable study with all of the major exoplanet detection methods. Here we introduce a suite of such models generated by a new tool, exoVista. The exoVista tool quickly generates thousands of models of quasi-self-consistent planetary systems around known nearby stars at scattered light wavelengths and efficiently records the position, velocity, spectrum, and physical parameters of all bodies as functions of time. The modeled planetary systems can be used to simulate surveys using the direct imaging, transit, astrometric, and radial velocity techniques, as well as the overlap of these different methods.
Discovery of Eight “Main-sequence Radio Pulse Emitters” Using the GMRT: Clues to the Onset of Coherent Radio Emission in Hot Magnetic Stars

Published: February 2022

Main-sequence radio pulse emitters (MRPs) are magnetic early-type stars from which periodic radio pulses, produced via electron cyclotron maser emission (ECME), are observed. Despite the fact that these stars can naturally offer suitable conditions for triggering ECME, only seven such stars have been reported so far within a span of more than two decades. In this paper, we report the discovery of eight more MRPs, thus more than doubling the sample size of such objects. These discoveries are the result of our sub-GHz observation program using the Giant Metrewave Radio Telescope over the years 2015–2021. Adding these stars to the previously known MRPs, we infer that at least 32% of the magnetic hot stars exhibit this phenomenon, thus suggesting that observation of ECME is not a rare phenomenon. The significantly larger sample of MRPs allows us for the first time to perform a statistical analysis comparing their physical properties. We present an empirical relation that can be used to predict whether a magnetic hot star is likely to produce ECME. Our preliminary analysis suggests that the physical parameters that play the primary role in the efficiency of the phenomenon are the maximum surface magnetic field strength and the surface temperature. In addition, we present strong evidence of the influence of the plasma density distribution on ECME pulse profiles. Results of this kind further motivate the search for MRPs, as a robust characterization of the relation between observed ECME properties and stellar physical parameters can only be achieved with a large sample.
The Galaxy Replacement Technique (GRT): A New Approach to Study Tidal Stripping and Formation of Intracluster Light in a Cosmological Context
Authors: Chun Kyungwon , Shin Jihye , Smith Rory , Ko Jongwan , Yoo Jaewon
Published: February 2022

We introduce the Galaxy Replacement Technique (GRT) that allows us to model tidal stripping of galaxies with very high mass (m
star = 5.4 × 104
M
⊙
h
−1) and high spatial resolution (10 pc h
−1), in a fully cosmological context, using an efficient and fast technique. The technique works by replacing multiple low-resolution dark-matter (DM) halos in the base cosmological simulation with high-resolution models, including a DM halo and stellar disk. We apply the method to follow the hierarchical buildup of a cluster since redshift ∼8 to now, through the hierarchical accretion of galaxies, individually or in substructures such as galaxy groups. We find we can successfully reproduce the observed total stellar masses of observed clusters since redshift ∼1. The high resolution allows us to accurately resolve the tidal stripping process and well describe the formation of ultralow surface brightness features in the cluster (μ

V
< 32 mag arcsec−2) such as the intracluster light (ICL), shells, and tidal streams. We measure the evolution of the fraction of light in the ICL and brightest cluster galaxy using several different methods. While their broad response to the cluster-mass growth history is similar, the methods show systematic differences, meaning we must be careful when comparing studies that use distinct methods. The GRT represents a powerful new tool for studying tidal effects on galaxies and exploring the formation channels of the ICL in a fully cosmological context and with large samples of simulated groups and clusters.
Variational Image Feature Extraction for the Event Horizon Telescope
Authors: Tiede Paul , Broderick Avery E. , Palumbo Daniel C. M.
Published: February 2022

Imaging algorithms form powerful analysis tools for very long baseline interferometry (VLBI) data analysis. However, these tools cannot measure certain image features (e.g., ring diameter) by their nonparametric nature. This is unfortunate since these image features are often related to astrophysically relevant quantities such as black hole mass. This paper details a new general image feature-extraction technique that applies to a wide variety of VLBI image reconstructions called variational image domain analysis. Unlike previous tools, variational image domain analysis can be applied to any image reconstruction regardless of its structure. To demonstrate its flexibility, we analyze thousands of reconstructions from previous Event Horizon Telescope synthetic data sets and recover image features such as diameter, orientation, and ellipticity. By measuring these features, our technique can help extract astrophysically relevant quantities such as the mass and orientation of the central black hole in M87.
Cosmic Near-infrared Background Tomography with SPHEREx Using Galaxy Cross-correlations
Authors: Cheng Yun-Ting , Chang Tzu-Ching
Published: February 2022

The extragalactic background light (EBL) consists of integrated light from all sources of emission throughout the history of the universe. At near-infrared wavelengths, the EBL is dominated by stellar emission across cosmic time; however, the spectral and redshift information of the emitting sources is entangled and cannot be directly measured by absolute photometry or fluctuation measurements. Cross-correlating near-infrared maps with tracers of known redshift enables EBL redshift tomography, as EBL emission will only correlate with external tracers from the same redshift. Here, we forecast the sensitivity of probing the EBL spectral energy distribution as a function of redshift by cross-correlating the upcoming near-infrared spectro-imaging survey, SPHEREx, with several current and future galaxy redshift surveys. Using a model galaxy luminosity function, we estimate the cross power spectrum clustering amplitude on large scales, and forecast that the near-infrared EBL spectrum can be detected tomographically out to z ∼ 6. We also predict a high-significance measurement (∼102–104
σ) of the small-scale cross power spectrum out to z ∼ 10. The amplitudes of the large-scale cross power spectra can constrain the cosmic evolution of the stellar synthesis process through both continuum and the line emission, while on the nonlinear and Poisson noise scales, the high-sensitivity measurements can probe the mean spectra associated with the tracer population across redshift.
Dependence of the Ratio of Total to Visible Mass on Observable Properties of Sloan Digital Sky Survey MaNGA Galaxies
Authors: Douglass Kelly A. , Demina Regina
Published: February 2022

Using spectroscopic observations from the Sloan Digital Sky Survey Mapping Nearby Galaxies at Apache Point Observatory Data Release 15, we study the relationships between the ratio of total to visible mass and various parameters characterizing the evolution and environment of the galaxies in this survey. Measuring the rotation curve with the relative velocities of the Hα emission line across a galaxy’s surface, we estimate each galaxy’s total mass. We develop a statistical model to describe the observed distribution in the ratio of total to visible mass, from which we extract the most probable value of this mass ratio for a given sample of galaxies. We present the relationships between the ratio of total to visible mass and several characteristics describing galactic evolution, such as luminosity, gas-phase metallicity, distance to the nearest neighbor, and position on the color–magnitude diagram. We find that faint galaxies with low metallicities, typically in the blue cloud, have the highest ratios of total to visible mass. This mass ratio is significantly reduced when we include the H i mass in the total visible mass, implying that feedback mechanisms are not as strong in low-mass galaxies as previously thought. Those galaxies that exhibit the second-highest ratios of total to visible mass are the brightest with high metallicities, typically members of the red sequence or green valley. Active galactic nucleus activity is likely both the quenching mechanism and the feedback that drives the mass ratio higher in these massive galaxies. Finally, we introduce a parameterization that predicts a galaxy’s ratio of total to visible mass based only on its photometry and luminosity.

The type Iax SN 2012Z in NGC 1309 is the only white dwarf supernova with a detected progenitor system in pre-explosion observations. Deep Hubble Space Telescope (HST) images taken before SN 2012Z show a luminous, blue source that we have interpreted as a helium-star companion (donor) to the exploding white dwarf. We present here late-time HST observations taken ∼1400 days after the explosion to test this model. We find the SN light curve can empirically be fit by an exponential-decay model in magnitude units. The fitted asymptotic brightness is within 10% of our latest measurements and approximately twice the brightness of the pre-explosion source. The decline of the light curve is too slow to be powered by 56Co or 57Co decay: if radioactive decay is the dominate power source, it must be from longer half-life species like 55Fe. Interaction with circumstellar material may contribute to the light curve, as may shock heating of the companion star. Companion-star models underpredict the observed flux in the optical, producing most of their flux in the UV at these epochs. A radioactively heated bound remnant, left after only a partial disruption of the white dwarf, is also capable of producing the observed excess late-time flux. Our analysis suggests that the total ejecta + remnant mass is consistent with the Chandrasekhar mass for a range of SNe Iax.
Nurses as Content Experts, Mentors, and Judges at Collaborative Innovation Sprints

Published: February 2022

The COVID-19 pandemic continues to reveal unique patient needs that require innovative problem-solving approaches. While a meeting of collaborative experts to solve problems is not novel, the formal inclusion of nurses as content experts at these types of events is less typical. To date, no reports of outcomes related to the inclusion of registered nurses (RNs) with any level of education and certification and in any role at an interprofessional hackathon are found in the extant literature. This article discusses participation of nurses as content experts in hackathon events, with information about principles of innovation, characteristics of innovators, hackathons, and the iterative process. We report methods, results, and include discussion about a descriptive survey study that considered perceptions of interprofessional participants in two hackathons held in 2020. Our analysis adds preliminary information about participants perceptions regarding collaboration with consulting nurses as content experts.
La paternité spirituelle
Authors: Goujon Patrick C. , Winter Jean-Pierre , Sarthou-Lajus Nathalie
Published: February 2022

La question des titres à reconnaître aux ministres de l’Église catholique interroge dans la mesure où ils ont pu semer le trouble et participer aux différentes formes d’abus de pouvoir. Parmi ces titres, celui de « père », ainsi que la fonction de paternité spirituelle qu’il recouvre, est lourd d’ambiguïté, notamment pour des enfants. Il nous paraît nécessaire de croiser le regard d’un théologien catholique et celui d’un psychanalyste, fin connaisseur du judaïsme, pour mieux en comprendre l’histoire, les spécificités et les menaces.
Les instruments au service de la réduction des inégalités sociales de santé selon les acteurs des agences régionales de santé : entre changement et continuité
Authors: Porcherie Marion
Published: February 2022

Réduire les inégalités sociales de santé (ISS) implique une action des politiques publiques, lesquelles doivent mettre en musique une action concertée sur un ensemble de déterminants sociaux de la santé. La manière de mener ces actions et les instruments qu’elles mobilisent ne sont pas toujours explicités dans la littérature internationale. Cet article s’intéresse aux instruments mobilisés par les agences régionales de santé (ARS) en France pour agir sur les ISS. À partir de l’analyse qualitative d’entretiens auprès d’acteurs institutionnels, nous identifions et analysons la variété et les types d’instruments d’action publique mobilisés par les ARS en fonction du type d’intervention publique auquel ils se rattachent. Nous comparons ensuite ces instruments à ceux que les acteurs préconisent de mettre en œuvre. Ces analyses nous conduisent à identifier deux instruments plébiscités par les acteurs sur lesquels nous proposons un focus : un instrument national, le contrat local de santé, et un instrument régional, le dispositif hospitalier de prévention. L’article s’intéresse ensuite à la tension que rencontre l’action de l’ARS dans sa lutte contre les ISS entre une forme de continuité et le changement que constitue la mobilisation de certains instruments d’action publique.
Comprendre les inégalités sociales de santé par la dimension émotionnelle du travail. Esquisse d’une typologie dans le secteur marchand de l’aide à domicile
Authors: Bonnet Thomas , Drais Éric
Published: February 2022

Cet article propose de montrer comment la dimension émotionnelle du travail dans le secteur marchand de l’aide à domicile éclaire les inégalités sociales de santé au travail. En s’appuyant sur une enquête menée au sein de deux agences d’aide à domicile et en se basant sur plus de 328 h d’observation et plus de 63 h d’entretiens enregistrés sur dictaphone, cette contribution souligne l’importance du travail émotionnel dans la problématique de la santé et de la sécurité au travail des aides à domicile. Généralement masquée, voire réfrénée, la dimension émotionnelle du travail peut constituer pourtant une ressource pour les professionnelles cherchant à acquérir une autonomie plus importante dans l’organisation de leur travail. Les jeux stratégiques de nature émotionnelle déployés par les intervenantes ne leur assurent toutefois pas toujours des bénéfices. En analysant les relations entre les ressources émotionnelles et les transactions identitaires opérées, l’article met en évidence trois trajectoires de santé typiques : celles qui réussissent, celles qui tiennent et celles qui partent. La compréhension de tels enjeux éclaire la prévention de la désinsertion professionnelle dans un milieu particulièrement exposé.
Nuevas perspectivas en torno a la fe y el mérito en la obra de Hilario de Poitiers
Authors: Alba López Almudena
Published: February 2022

L’influence du corpus paulinien sur l’œuvre et la pensée d’Hilaire de Poitiers est évidente autant dans l’approche exégétique de l’évêque vis-à-vis des textes bibliques que dans les sujets qu’il traite. Parmi ceux-ci, la justification par la foi fait l’objet d’un développement remarquable dans ses œuvres principales, en particulier dans le Commentarium in Matthaeum , dans laquelle l’évêque de Poitiers souligne la capacité exclusive de la foi pour justifier l’être humain et l’impuissance des œuvres pour l’atteindre. Cette radicalité apparente de son approche dans sa première œuvre connue a donné lieu à une compréhension partiale du traitement que fait Hilaire de la justification par la foi. Dans cet article nous analyserons la véritable nature du rôle que jouent la foi et le mérite pour le salut dans l’ensemble des écrits de l’évêque de Poitiers tout en mettant sa doctrine en contexte avec celle de l’Apôtre.
Auguste Comte et l’avenir
Authors: Fedi Laurent
Published: February 2022

Auguste Comte (1798-1857) construit une vision unifiée de l’histoire humaine débouchant sur un état final considéré comme définitif. Pour cela, il mobilise plusieurs registres, dont certains peuvent paraître mutuellement contradictoires : l’ingénierie scientifique appliquée à la science sociale, la transposition laïque du thème chrétien de la venue prochaine du Royaume, le genre utopique et même la littérature d’anticipation. La superposition de ces stratégies de légitimation vient pallier les limites de la science pour la réorganisation sociale. Depuis le xx e  siècle nous sommes revenus du mythe du progrès et de sa dimension eschatologique, mais au prix d’une désillusion et d’une perte de sens collectif, voire d’un catastrophisme qui ressuscite d’anciennes terreurs apocalyptiques.
Gratitude Strengthens the Relationship Between Leisure Social Support and Self-Rated Health Among Nursing Home Residents
Authors: Chang Liang-Chih , Dattilo John , Huang Fei-Hsin
Published: February 2022

A central outcome indicator of person-oriented services in primary health care is self-rated health (SRH). Therefore, promoting SRH among nursing home residents is valuable. We examined whether demographic variables, gratitude, and leisure social support (LSS) related to SRH, and whether gratitude moderated the relationship between LSS and SRH. To collect demographic information and measure gratitude, LSS, and SRH, we conducted face-to-face interviews with 237 participants from four nursing homes in Taiwan. We used hierarchical regression analysis to examine data. Results demonstrated that duration of residence, gratitude, and LSS predicted SRH, and that gratitude interacted with LSS. We discuss implications of these results in terms of facilitating gratitude to promote SRH among nursing home residents and guiding them to seek sources of LSS. In particular, we further discuss how gratitude strengthens the relationship between LSS and SRH. [

“They Just Took Him Out of My Life”: Nursing Home Care Partner Experiences During the COVID-19 Pandemic
Authors: Kusmaul Nancy , Miller Vivian J. , Cheon Ji Hyang
Published: February 2022

The current study describes the impact of visitation restrictions on nursing home residents and their family caregivers from caregivers' perspectives during the coronavirus disease 2019 (COVID-19) pandemic. Family caregivers (
N
= 31) were recruited via social media and email listservs to complete an online survey. Researchers also completed semi-structured, one-on-one interviews with interested participants (
n
= 17). Caregivers reported experiencing disconnect from residents, confusion on the part of residents, and sadness. All caregivers were of the opinion that residents with dementia declined during lockdown and that they and their residents experienced irreparable harm from the prolonged separation. Providers, policymakers, and researchers must use the lessons learned from the COVID-19 pandemic in future situations. Protecting residents from a deadly disease is important, but long-term separation from family caregivers cannot be condoned again. [
