Investigación enfermera: más allá de la responsabilidad del profesional
Authors: Ochando-García Antonio
Published: December 2021

“Hablar del personal de enfermería es hablar de los profesionales del cuidado, es hablar de la excelencia sanitaria, es hablar de la competencia investigadora, y por supuesto, es hablar de la cercanía con los pacientes. Son fundamentales en nuestro sistema de salud”. Con estas palabras de Carolina Darias, Ministra de Sanidad, comienza un video promovido por Investen-isciii y que se difundía recientemente por redes sociales.La investigación constituye junto a la asistencia, la docencia y la gestión, los cuatro pilares en los que se fundamenta la disciplina enfermera. Sin embargo, no ha sido hasta la incorporación de los estudios de enfermería en el Espacio Europeo de Educación Superior y la obtención del título de Grado, cuando desde nuestra profesión se ha podido acceder al segundo y tercer ciclo de las enseñanzas universitarias oficiales, permitiendo la realización de los estudios de doctorado, que supone el nivel académico más alto y la capacitación investigadora de una profesión.

Published: December 2021

The article presents the results of hydrological studies of the north-eastern part of the Barents Sea. The observations were made in the oceanographic expeditions R/W “Dalnie Zelentsy” of the MMBI RAS in October–November 2019 and 2020. The analysis of a series of hydrological sections is carried out, which details the vision of the structure of the waters and currents of the studied area. In the water structure, two streams of Atlantic waters are distinguished. The flows are directed opposite to each other and are located in different deep layers. The Atlantic stream emerging from the Barents Sea is identified as a branch of the warm New Earth current. At the beginning of the winter,the current spreads in a layer from the surface to 50–75 m. The Atlantic waters flowing into the Barents Sea are identified as a branch of the deep current of the St. Anna trench. They come from the Polar Basin and pass into the sea from east to west up to 62–60o E.

Environmental security as an international legal category
Authors: Polych Valeriia
Published: December 2021

Problem setting. The problem of environmental security has gone beyond national borders and acquired a planetary character. If before the issue of ensuring the environmental security of countries was solely their internal affair, over time, state borders from an environmental point of view gradually lost their importance, became transparent.

Analysis of recent researches and publications. The study of theoretical or some practical aspects of the legal nature of environmental safety were engaged in domestic and foreign scientists, among which are the works of: A.P. Hetman, H.V. Anisimova, G.I. Balyuk, S.A. Bogolyubova, M.M. Brinchuk, I.I. Karakash, T.G. Kovalchuk, V.V. Kostytsky and others.

Target of research is to determine the essence and features of environmental safety as a legal category in terms of international law.

Article’s main body. The article examines the definition of «environmental security» as a legal category. Its legal nature and its connection to international security are being established. In particular, environmental security as a legal category is considered from two points of view, as a certain state of protection of a person from threats caused by an thropogenic impact on natural objects, and as a system of legal instruments regulating the use of natural resources for their protection, as well as prevention and counteraction to threats that have a detrimental effect on the environment. Through the analysis of international legal acts, modern approaches of the international community to ensuring environmental security are determined.

The international mechanism for environmental security is constantly evolving, it should be recognized that it is unfortunately not perfect and is not able to fully solve today's environmental problems, as well as to prevent an environmental catastrophe on a global scale. By concluding international agreements alone, it is impossible to ensure effective protection of all elements of the natural environment.

Conclusions and prospects for the development. Therefore, it is important to consolidate the efforts of all participants in international communication in developing common approaches to solving this problem and actively using numerous international treaties and soft law instruments, best national practices, and involving civil society.

The article explores the role of various financial incentive instruments in optimizing the financial mechanism of logistics development in the construction sector of the economy. The author focuses on the necessary to use a synergistic approach in the study of efficiency issues of two related industries - logistic and construction sectors of the national economy. Positive factors such as convenient location, available transport potential, established logistics system, material and resource base and the potential of domestic producers determine the rapid development of the construction industry, which brings its significant contribution to the development of the national economy of Poland. At the same time, the main factor contributing to the development of construction business is domestic production of construction materials. In this context, it should be noted that the country has developed the potential of its own production of building materials, there is a sufficient fleet of construction machinery and construction equipment, innovative technologies are being introduced, highly qualified personnel, etc. Comprehensive assessment of financial-investment and transport-logistic potentials in the context of the regions, as well as differentiated approach allowed to offer a matrix of financial stimulation tools for the development of logistics in construction in a horizontal and vertical strategy. At a time of intensifying crisis phenomena, simultaneous stagnation of regional development and increasing competition in the globalized world, the issues of selecting effective instruments of financial support for the development of national transport and logistics system and construction sector of economy gain priority importance, as they can generate a significant increase in the gross domestic income of the state budget and become one of the main sources of ensuring Polish competitiveness.

CAPACITY SHARING STRATEGY WITH SUSTAINABLE REVENUE-SHARING CONTRACTS
Authors: Chen Junlong , Shi Jiayan , Liu Jiali
Published: December 2021

This paper develops a duopoly model to analyse capacity sharing strategy and the optimal revenue-sharing contract under a two-part tariff and examines the effects of capacity sharing, cost, and sharing charges in three scenarios. The paper uses the two-part tariff method and adds a more realistic assumption of incremental marginal costs to improve the research on capacity sharing strategies. The results show that capacity constraints affect the sustainable development of firms. A sustainable revenue-sharing contract can create a win-win situation for both firms and promote capacity sharing. Capacity sharing, cost, and the revenue-sharing rate have different impacts in different scenarios; the optimal revenue-sharing rate and fixed fee can be determined to maximise the profits of firms that share capacity. However, capacity sharing may not improve social welfare.
Positron Effects on Polarized Images and Spectra from Jet and Accretion Flow Models of M87* and Sgr A*
Authors: Emami Razieh , Anantua Richard , Chael Andrew A. , Loeb Abraham
Published: December 2021

We study the effects of including a nonzero positron-to-electron fraction in emitting plasma on the polarized spectral energy distributions and submillimeter images of jet and accretion flow models for near-horizon emission from M87* and Sgr A*. For M87*, we consider a semi-analytic fit to the force-free plasma regions of a general relativistic magnetohydrodynamic jet simulation, which we populate with power-law leptons with a constant electron-to-magnetic pressure ratio. For Sgr A*, we consider a standard self-similar radiatively inefficient accretion flow where the emission is predominantly from thermal leptons with a small fraction in a power-law tail. In both models, we fix the positron-to-electron ratio throughout the emission region. We generate polarized images and spectra from our models using the general relativistic ray tracing and radiative transfer from GRTRANS. We find that a substantial positron fraction reduces the circular polarization fraction at IR and higher frequencies. However, in submillimeter images, higher positron fractions increase polarization fractions due to strong effects of Faraday conversion. We find an M87* jet model that best matches the available broadband total intensity, and 230 GHz polarization data is a sub-equipartition, with positron fraction of ≃10%. We show that jet models with significant positron fractions do not satisfy the polarimetric constraints at 230 GHz from the Event Horizon Telescope (EHT). Sgr A* models show similar trends in their polarization fractions with increasing pair fraction. Both models suggest that resolved, polarized EHT images are useful to constrain the presence of pairs at 230 GHz emitting regions of M87* and Sgr A*.
Infrared Spectroscopy of Jet-cooled “GrandPAHs” in the 3–100 μm Region
Authors: Lemmens A. K. , Rijs A. M. , Buma W. J.
Published: December 2021

Although large polycyclic aromatic hydrocarbons (PAHs) are likely to be responsible for IR emission of gaseous and dusty regions, their neutral experimental high-resolution gas-phase IR spectra—needed to construct accurate astronomical models—have so far remained out of reach because of their nonvolatility. Applying laser desorption to overcome this problem, we report here the first IR spectra of the jet-cooled large PAHs coronene (C24H12), peropyrene (C26H14), ovalene (C32H14), and hexa(peri)benzocoronene (C42H18) in the 3–100 μm region. Apart from providing experimental spectra that can be compared directly to astronomical data, such IR spectra are crucial for assessing the accuracy of theoretically predicted spectra used to interpret interstellar IR emission. Here we use the experimental spectra to evaluate the performance of conventional calculations using the harmonic approximation, as well as calculations with an anharmonic (GVPT2) treatment. The harmonic prediction agrees well with the experiment between 100 and 1000 cm−1 (100 and 10 μm) but shows significant shortcomings in the combination band (1600–2000 cm−1, 6.25–5 μm) and CH-stretch (2950–3150 cm−1, 3.4–3.17 μm) regions. Especially the CH-stretch region is known to be dominated by the effects of anharmonicity, and we find that large PAHs are no exception. However, for the CH out-of-plane region (667–1000 cm−1, 15–10 μm) the anharmonic treatment that significantly improves the predicted spectra for small PAHs leads to large and unrealistic frequency shifts, and intensity changes for large PAHs, thereby rendering the default results unreliable. A detailed analysis of the results of the anharmonic treatment suggests a possible route for improvement, although the underlying cause for the large deviations remains a challenge for theory.

We report on a Nuclear Spectroscopic Telescope Array (NuSTAR) observation of the young, energetic pulsar PSR J1617–5055. Parkes Observatory 3 GHz radio observations of the pulsar (taken about 7 yr before the NuSTAR observations) are also reported here. NuSTAR detected pulsations at a frequency of f ≈ 14.4 Hz (P ≈ 69.44 ms) and, in addition, the observation was long enough to measure the source’s frequency derivative,

Hz s−1. We find that the pulsar shows one peak per period at both hard X-ray and radio wavelengths, but that the hard X-ray pulse is broader (having a duty cycle of ∼0.7), than the radio pulse (having a duty cycle of ∼0.08). Additionally, the radio pulse is strongly linearly polarized. J1617's phase-integrated hard X-ray spectrum is well fit by an absorbed power-law model, with a photon index Γ = 1.59 ± 0.02. The hard X-ray pulsations are well described by three Fourier harmonics, and have a pulsed fraction that increases with energy. We also fit the phase-resolved NuSTAR spectra with an absorbed power-law model in five phase bins and find that the photon index varies with phase from Γ = 1.52 ± 0.03 at phases around the flux maximum to Γ = 1.79 ± 0.06 around the flux minimum. Last, we compare our results with other pulsars whose magnetospheric emission is detected at hard X-ray energies and find that, similar to previous studies, J1617's hard X-ray properties are more similar to the MeV pulsars than the GeV pulsars.
Central X-Ray Point Sources Found to Be Abundant in Low-mass, Late-type Galaxies Predicted to Contain an Intermediate-mass Black Hole

Published: December 2021

Building upon three late-type galaxies in the Virgo cluster with both a predicted black hole mass of less than ∼105
M
⊙ and a centrally located X-ray point source, we reveal 11 more such galaxies, more than tripling the number of active intermediate-mass black hole candidates among this population. Moreover, this amounts to a ∼36 ± 8% X-ray detection rate (despite the sometimes high, X-ray-absorbing, H i column densities), compared to just 10 ± 5% for (the largely H i-free) dwarf early-type galaxies in the Virgo cluster. The expected contribution of X-ray binaries from the galaxies’ inner field stars is negligible. Moreover, given that both the spiral and dwarf galaxies contain nuclear star clusters, the above inequality appears to disfavor X-ray binaries in nuclear star clusters. The higher occupation, or rather detection, fraction among the spiral galaxies may instead reflect an enhanced cool gas/fuel supply and Eddington ratio. Indeed, four of the 11 new X-ray detections are associated with known LINERs or LINER/H ii composites. For all (four) of the new detections for which the X-ray flux was strong enough to establish the spectral energy distribution in the Chandra band, it is consistent with power-law spectra. Furthermore, the X-ray emission from the source with the highest flux (NGC 4197: L

X
≈ 1040 erg s−1) suggests a non-stellar-mass black hole if the X-ray spectrum corresponds to the “low/hard state”. Follow-up observations to further probe the black hole masses, and prospects for spatially resolving the gravitational spheres of influence around intermediate-mass black holes, are reviewed in some detail.

Published: December 2021

Total protein describes the liver's ability to synthesize proteins and metabolize substances in the blood. Bovine serum can be used as a control material because the total protein analyte in bovine blood serum is almost identical to the analyte in human serum. The researchers intend to determine the homogeneity and stability of bovine serum with the addition of 7,5% ethylene glycol preservative after being stored for 12 weeks at -20°C as an alternative to control serum for total protein levels. This research used survey analytics using a one-group pretest-posttest research design.  Data analysis used ISO 13528 2005 calculations. From the examination of the total protein level in the serum, the value of Xr – Yr = 0.23817, which is where the value meets the test criteria according to |  Xr - Yr |  <0.36, that is 0.23817 <0.91585. The total protein content of bovine serum was homogeneous and stable with the addition of 7.5% ethylene glycol stored at -20oC for 12 weeks.
Deep Semi-Supervised Image Classification Algorithms: a Survey
Authors: Vanyan Ani , Khachatrian Hrant
Published: December 2021

Semi-supervised learning is a branch of machine learning focused on improving the performance of models when the labeled data is scarce, but there is access to large number of unlabeled examples. Over the past five years there has been a remarkable progress in designing algorithms which are able to get reasonable image classification accuracy having access to the labels for only 0.1% of the samples. In this survey, we describe most of the recently proposed deep semi-supervised learning algorithms for image classification and identify the main trends of research in the field. Next, we compare several components of the algorithms, discuss the challenges of reproducing the results in this area, and highlight recently proposed applications of the methods originally developed for semi-supervised learning.

Lorsqu’un enfant est déplacé de sa famille à une autre, un sentiment de déloyauté à l’égard de ses parents se développe chez lui en même temps que naissent chez l’assistante familiale un fantasme de rapt et, chez les parents, un vécu d’effraction. S’ensuivent autant de troubles contrariant l’efficacité de la mesure : agressivité des parents, hostilité de l’enfant et sentiment de culpabilité de l’assistante familiale, etc. Est-ce là une fatalité intrinsèque au dispositif « placement familial » et à la nature de la famille ? L’auteur essaie de montrer qu’il s’agit en fait de conséquences néfastes des représentations que nous avons sur ce que nous croyons devoir être une famille et des parents pour un enfant. Il montre également, exemple à l’appui, qu’une évolution de nos conceptions de la famille, donc de notre conception du placement familial, peut permettre d’atténuer ces manifestations, dans l’intérêt de l’enfant.
Fratries : séparer pour soigner ?
Authors: Baticle William , Hétier Claire-Marie , Rottman Hana
Published: December 2021

Dans le domaine du placement d’enfants, la loi de 1996 préconisant le maintien de la communauté de vie des frères et sœurs est souvent comprise comme une injonction sine qua non . Cet article se fait l’écho des observations d’une équipe pluridisciplinaire (éducateurs, psychologue, psychanalyste) engagée depuis de longues années dans l’accueil familial qui dévoilent, à travers une analyse à la fois quantitative et clinique, une réalité qui vient nuancer cet impératif. Les auteurs montrent que, dans un certain nombre de cas, le maintien de la communauté de vie de la fratrie contribue à l’entretien de la pathologie des liens familiaux et à l’aliénation du sujet. Pourtant, il est possible d’imaginer des dispositifs où séparation de la fratrie n’est pas synonyme de rupture des liens fraternels.
Soyez créatifs ! Esthétisation et créativité à l’âge du capitalisme esthétique
Authors: Reckwitz Andreas , Windels Loïc
Published: December 2021

À rebours de la thèse sur la modernité comme une époque où la rationalisation aurait pris le dessus sur la dimension esthétique et affective, Reckwitz repère les différentes étapes de la construction d’un capitalisme esthétique, où l’inventivité revêt désormais un rôle crucial. Tandis que la créativité était brandie par les avant-gardes artistiques du xix e  et du xx e  siècle comme un idéal permettant de subvertir les normes sociales, la créativité représente aujourd’hui elle-même une norme incontournable. « Soyez créatifs » : cette injonction paradoxale s’applique désormais à tous les sujets du capitalisme tardif. Extrait de sa grande étude sur L’Invention de la créativité , ce chapitre replace l’enjeu de l’esthétisation au cœur de ce que Reckwitz nomme le « dispositif de la créativité ».
Cimetières et fantômes
Authors: Sangsue Daniel
Published: December 2021

Cet article étudie la façon dont la littérature du xix e  siècle représente les fantômes dans les cimetières, à travers un corpus qui touche plusieurs genres, parcourt le siècle et ne se limite pas à la France. Ce corpus montre que l’imaginaire des revenants profite des nouvelles conceptions du cimetière et de la mort qui voient alors le jour et donnent lieu à des pratiques culturelles comme le culte des défunts, la visite au cimetière et une certaine sociabilité posthume. On examine aussi comment cet imaginaire est stimulé par le spiritisme, alimenté par des croyances plus anciennes telles que le psychopannychisme et le purgatoire, ainsi que par la littérature des graveyard poets du xviii e  siècle.
Le cimetière du XIX e siècle revisité par l’archéologie funéraire. Entretien avec Patrice Courtaud et Anne Richier, propos recueillis par Emmanuel Fureix
Authors: Courtaud Patrice , Richier Anne
Published: December 2021

Notre connaissance des cimetières du xix e  siècle privilégie les nécropoles prestigieuses aux dépens des cimetières les plus modestes, des sépultures des classes populaires, destinées à disparaître du paysage funéraire. L’archéologie permet d’approcher cet envers funéraire du xix e  siècle. Depuis une quinzaine d’années, des progrès fulgurants ont été rendus possibles par des chantiers de fouilles de cimetières oubliés, effacés, ou sans qualités. L’entretien donne la parole à deux archéologues, Anne Richier et Patrice Courtaud, acteurs de deux chantiers majeurs de fouilles de cimetières du xix e  siècle : un cimetière d’esclaves en Guadeloupe et un cimetière aux marges de la ville de Marseille, le cimetière des Crottes, en usage pendant tout le xix e  siècle avant sa fermeture en 1905. Ces deux nécropoles interrogent également le rapport du xix e  siècle aux normes funéraires et le processus d’effacement des cimetières non patrimonialisés.
Essai autour de la temporalité fragmentaire du « Petit Bossu » de Walter Benjamin
Authors: Sferco Senda
Published: December 2021

Ce texte présente un parcours libre de la question du temps d’après la perspective benjaminienne, afin de récupérer la puissance philosophique qui émerge de son traitement fragmentaire de la temporalité. En effet, face aux grandes conceptualisations modernes de l’histoire et de la mémoire, W. Benjamin propose des figures attentives à repérer l’importance de faire expérience de la discontinuité. La figure du « Petit Bossu », sera une porte d’entrée dans l’espace-temps de l’enfance et dans les remparts d’une mémoire chargée d’oublis, qui donc ne se révèle à nous au présent que « par moitiés ».
Global dynamics of a Huanglongbing model with a periodic latent period
Authors: Hong Yan , Liu Xiuxiang , Yu Xiao
Published: December 2021

Huanglongbing (HLB) is a disease of citrus that caused by phloem-restricted bacteria of the Candidatus Liberibacter group. In this paper, we present a HLB transmission model to investigate the effects of temperature-dependent latent periods and seasonality on the spread of HLB. We first establish disease free dynamics in terms of a threshold value \begin{document}$ R^p_0 $\end{document}, and then introduce the basic reproduction number \begin{document}$ \mathcal{R}_0 $\end{document} and show the threshold dynamics of HLB with respect to \begin{document}$ R^p $\end{document} and \begin{document}$ \mathcal{R}_0 $\end{document}. Numerical simulations are further provided to illustrate our analytic results.

Published: December 2021

By using the operator theory, we establish the Green's function for Caputo fractional differential equation under Sturm-Liouville boundary conditions. The results are new, the method used in this paper will provide some new ideas for the study of this kind of problems and easy to be generalized to solving other problems.
Circular breakdown of neural networks due to loss of deubiquitinating enzyme (UCH-L1) in gracile axonal dystrophy (gad) mouse

Published: December 2021

Gracile axonal dystrophy (gad) mouse shows tremor, ataxia and muscular atrophy of hind limbs from about 80-days of age. These clinical features become progressively severe to death. Pathological examination reveals that main and early axonal degeneration exists in a long ascending nervous tract in dorsal column of the spinal cord: gracile nucleus and fascicules. Similar lesions are seen in axonal terminals of peripheral sensory (muscle spindles) and motor endplates. Most striking features of axonal dystrophy are “dying-back” axonal degeneration with partial swellings (“spheroids” in matured type) which come to be most frequently in gracile nucleus, followed by in order of gracile fasciculus of cervical, thoracic and lumber cord levels. Immunocytochemical increase of glial fibrillary acidic protein (GFAP) and substance P (SP) is seen in reactive astrocytes and degenerating axons. Likewise, amyloid precursor protein (APP) and amyloid β-protein (AβP) activity become positive in axons and astrocytes along ascending tract. Moreover, ubiquitin-positive dot-like structures accumulate in gracile nucleus, spinocerebellar tract, and cerebellum in gad mice after 9th-week old. Ubiquitinated structures are localized in spheroids with a larger diameter than normal. The gad mutation is caused by an in-frame deletion including exon 7 and 8 of UCH-L1 gene, encoding the ubiquitin c-terminal hydrolase (UCH) isozyme (UCH-L1) selectively expressed in nervous system and testis/ovary. The gad allele encodes a truncated UCH-L1 lacking a segment of 42 amino acids containing catalytic site. The evaluation as mouse models for Parkinson's and Alzheimer's diseases and the collapse of synapse-axon circulation around central nervous system from peripheral nervous system are discussed.
Telegraph systems on networks and port-Hamiltonians. Ⅱ. Network realizability
Authors: Banasiak Jacek , Błoch Adam
Published: December 2021

Hyperbolic systems on networks often can be written as systems of first order equations on an interval, coupled by transmission conditions at the endpoints, also called port-Hamiltonians. However, general results for the latter have been difficult to interpret in the network language. The aim of this paper is to derive conditions under which a port-Hamiltonian with general linear Kirchhoff's boundary conditions can be written as a system of \begin{document}$ 2\times 2 $\end{document} hyperbolic equations on a metric graph \begin{document}$ \Gamma $\end{document}. This is achieved by interpreting the matrix of the boundary conditions as a potential map of vertex connections of \begin{document}$ \Gamma $\end{document} and then showing that, under the derived assumptions, that matrix can be used to determine the adjacency matrix of \begin{document}$ \Gamma $\end{document}.
Beatriz de Lauria y Jérica, una dama valenciana en la Andalucía del siglo XIV
Authors: Carriazo Rubio Juan Luis
Published: December 2021

El matrimonio, en 1335, de Beatriz de Lauria con el segundo señor de Marchena constituye un acontecimiento fundamental en el proceso de consolidación del linaje de los Ponce de León andaluces. Al mismo tiempo, modifica por completo las circunstancias vitales de Beatriz, no solo por el cambio de reino que supone su traslado de Valencia a Sevilla, sino también por las complejas relaciones entre Castilla y Aragón durante las décadas centrales del siglo XIV. Todo ello afectó a sus aspiraciones señoriales en territorio valenciano, dificultadas por la actuación de sus hermanos Jaime y Pedro de Jérica. El hecho de que sobreviviera a su esposo durante más de veinte años nos permite analizar su actuación en el contexto andaluz, aspecto poco conocido y de gran interés en un reinado, como el de Pedro I de Castilla, tan adverso para los grandes linajes sevillanos.
El mausoleo de la dinastía Trastámara en la catedral de Toledo
Authors: Gumiel Campos Pablo
Published: December 2021

El rey Enrique II de Castilla (1366-1379), fundó por orden testamentaria una capilla real en la catedral de Toledo que durante varias generaciones actuó como el panteón real de la familia Trastámara. Esta capilla real fue abandonada en el siglo XVI, y tan solo los sepulcros originales fueron preservados tras su traslado a la Capilla de Reyes Nuevos de la catedral primada. El objertivo de este artículo es realizar un estudio documental y arquitectónico que nos permita conocer cómo era la estructura y composición original de este mausoleo bajo medieval.
