Friedrich Schlegel's understanding of history in the context of the philosophy of history of the XX – early XXI centuries
Authors: Макарьев И.В.
Published: October 2021

в философии истории ХХ в. можно выделить двоякую тенденцию. С одной стороны, классическая философия истории подвергается радикальной критике (в немецкой философской герменевтике, французском структурализме и постструктурализме, англоязычной аналитической философии), а с другой стороны, она продолжается и развивается в различных концепциях и теориях («столкновение цивилизаций» С. Хантингтона, «конец истории» Ф. Фукуямы). Такая двойственность (критика философии истории и ее развитие) не является характеристикой только нашей современности. Выдающийся немецкий филолог и философ Фридрих Шлегель (1772–1829) в ситуации философской революции рубежа XVIII–XIX вв. постарался соединить эти две позиции в одну, что и стало предметом анализа автора статьи.

in the philosophy of the history of the twentieth century, a twofold tendency can be distinguished. On the one hand, the classical philosophy of history is subjected to radical criticism (in German philosophical hermeneutics, French structuralism and poststructuralism, English-speaking analytical philosophy), and on the other hand, it continues and develops in various concepts and theories (S. Huntington's "clash of civilizations", "end of history" F. Fukuyama). Such duality (criticism of the philosophy of history and its development) is not a characteristic only of our modernity. The outstanding German philologist and philosopher Friedrich Schlegel (1772–1829), in the situation of the philosophical revolution at the turn of the 18th–19th centuries, tried to combine these two positions into one, , which became the subject of the analysis of the author of the article.

Authors: Амирханян И.М.
Published: October 2021

в нашем исследовании рассматривается готовность педагогов к решению актуальных профессиональных задач и ее отличие от педагогического мастерства и профессиональной компетентности с позиций педагогики индивидуальности. Акцент делается на субъективной составляющей этого феномена, которая проявляется в первую очередь в мотивационной сфере, а также в эмоциональной, волевой сферах и в сфере саморегуляции педагога. Предлагаемый подход позволит выделить и описать уровни готовности педагогов применительно к решению задач, связанных с использованием ИКТ в образовательном процессе, наметить эффективные меры управленческого содействия ее развитию в образовательной организации.

our research substantiates the essence of teachers' readiness to solve urgent professional problems and its difference from pedagogical skills and professional competence from the standpoint of the pedagogy of individuality. The emphasis is on the subjective component of this phenomenon, which manifests itself primarily in the motivational sphere, as well as in the emotional sphere and in the sphere of teacher's self-regulation. This approach makes it possible to identify and describe the levels of teachers' readiness to solve problems associated with the use of ICT in the educational process, to outline effective measures for management support for their development in the educational organization.

The proposition concerning the relationship between job satisfaction and customer satisfaction is not novel in organizational behaviour research. The profound impact of job satisfaction in improving organizational productivity through satisfied and retained customers is well documented. The present study attempts to assess the relationship between job satisfaction and customer satisfaction from the employees' point of view in the Indian banking industry, an approach that is unique to the study. The relationship between an employee and the customer is of utmost importance, especially in the service sector industry like banking. Relevant statistical tools (using SPSS) were applied to a sample of 542 employees of commercial banks. The results confirmed a positive relationship between the two constructs. Thus, when employees are satisfied with their job, they perceive that they deliver superior service, thus making their customers happy and satisfied. Consequently, they will recommend their organization to others, thereby improving revenues. Exploring further, the study also tested some demographic variables with respect to job satisfaction and concluded that employees' level of management, and type of bank they work for, had a significant relationship, while age did not show any significant relationship with job satisfaction.

Chandra/LETGS Studies of the Collisional Plasma in 4U 1626–67
Authors: Hemphill Paul B. , Schulz Norbert S. , Marshall Herman L. , Chakrabarty Deepto
Published: October 2021

We present an analysis of Chandra/LETGS observations of the ultracompact X-ray binary (UCXB)4U 1626–67, continuing our project to analyze the existing Chandra gratings data of this interesting source. The extremely-low-mass, hydrogen-depleted donor star provides a unique opportunity to study the properties and structure of the metal-rich accreted plasma. There are strong, double-peaked emission features of O vii–VIII and Ne ix–X, but no other identified emission lines are detected. Our spectral fit simultaneously models the emission-line profiles and the plasma parameters, using a two-temperature collisionally-ionized plasma. Based on our line-profile fitting, we constrain the inclination of the system to 25–60° and the inner disk radius to ∼1500 gravitational radii, in turn constraining the donor mass to ≲0.026 M
⊙, while our plasma modeling confirms previous reports of high neon abundance in the source, establishing a Ne/O ratio in the system of 0.47 ± 0.04, while simultaneously estimating a very low Fe/O ratio of 0.0042 ± 0.0008 and limiting the Mg/O ratio to less than 1% by number. We discuss these results in light of previous work.

Polarimetric observations of fast radio bursts (FRBs) are a powerful resource for better understanding these mysterious sources by directly probing the emission mechanism of the source and the magneto-ionic properties of its environment. We present a pipeline for analyzing the polarized signal of FRBs captured by the triggered baseband recording system operating on the FRB survey of The Canadian Hydrogen Intensity Mapping Experiment (CHIME/FRB). Using a combination of simulated and real FRB events, we summarize the main features of the pipeline and highlight the dominant systematics affecting the polarized signal. We compare parametric (QU-fitting) and non-parametric (rotation measure synthesis) methods for determining the Faraday rotation measure (RM) and find the latter method susceptible to systematic errors from known instrumental effects of CHIME/FRB observations. These errors include a leakage artifact that appears as polarized signal near RM ∼ 0 rad m−2 and an RM sign ambiguity introduced by path length differences in the system’s electronics. We apply the pipeline to a bright burst previously reported (FRB 20191219F), detecting an RM of +6.074 ± 0.006 ± 0.050 rad m−2 with a significant linear polarized fraction (≳0.87) and strong evidence for a non-negligible circularly polarized component. Finally, we introduce an RM search method that employs a phase-coherent de-rotation algorithm to correct for intra-channel depolarization in data that retain electric field phase information and successfully apply it to an unpublished FRB, FRB 20200917A, measuring an RM of −1294.47 ± 0.10 ± 0.05 rad m−2 (the second largest unambiguous RM detection from any FRB source observed to date).
Early Universe Physics Insensitive and Uncalibrated Cosmic Standards: Constraints on Ωm and Implications for the Hubble Tension
Authors: Lin Weikang , Chen Xingang , Mack Katherine J.
Published: October 2021

To further gain insight into whether pre-recombination models can resolve the Hubble tension, we explore constraints on the evolution of the cosmic background that are insensitive to early universe physics. The analysis of the CMB anisotropy has been thought to highly rely on early universe physics. However, we show that the fact that the sound horizon at recombination being close to that at the end of the drag epoch is insensitive to early universe physics. This allows us to link the absolute sizes of the two horizons and treat them as free parameters. Jointly, the CMB peak angular size, baryon acoustic oscillations, and Type Ia supernovae can be used as early universe physics insensitive and uncalibrated cosmic standards, which measure the cosmic history from recombination to today. They can set strong and robust constraints on the post-recombination cosmic background, especially the matter density parameter with Ωm = 0.302 ± 0.008 (68% C.L.), assuming a flat Λ cold dark matter universe after recombination. When we combine these with other nonlocal observations, we obtain several constraints on H
0 with significantly reduced sensitivity to early universe physics. These are all more consistent with the Planck 2018 result than the local measurement results such as those based on Cepheids. This suggests a tension between the post-recombination, but nonlocal, observations, and the local measurements that cannot be resolved by modifying pre-recombination early universe physics.
Ne/O and Fe/O Characteristics of Large Solar Energetic Particle Events during Solar Cycles 23 and 24
Authors: Tan Lun C. , Malandraki Olga E.
Published: October 2021

We have examined the Ne/O and Fe/O characteristics of large solar energetic particle (SEP) events at the ion energy range of 3–40 MeV nucleon−1 during solar cycles 23 and 24. In each cycle, the solar activity displays an ∼3 yr rising phase and a longer declining phase. While Fe-poor events only appeared in the declining phase of cycle 23, the properties of Fe-rich events were similar in the rising phases of both cycles. Also, very few Fe-rich events were seen in the declining phase of cycle 24. In addition, the Ne/O data in the corona, solar wind, and SEP events consistently reveal that the characteristics of SEP events are mainly governed by the solar wind turbulence status that exhibits a significant difference between slow and fast streams. During the rising phase of the solar cycles, slow streams are dominated by the two-dimensional turbulence component, which significantly reduces the injection energy of the quasi-perpendicular (Q-Perp) shock acceleration. Also, slow streams have an increased Ne/O ratio and hence enhanced temperature of coronal suprathermals, favoring the occurrence of Fe-rich events. In contrast, in the declining phase of the solar cycles, the fast streams are dominated by the slab turbulence component, which could significantly increase the injection energy of the Q-Perp shock acceleration. Consequently, in fast streams, most Fe-rich events originate from jet suprathermals. The coronal suprathermals may produce the Fe-poor events having abnormally low Ne/O ratios provided the speed of the associated coronal mass ejection is large enough.
Turbulent Magnetic Dynamos with Halo Lags, Winds, and Jets
Authors: Henriksen R. N. , Irwin Judith
Published: October 2021

This paper presents scale-invariant/self-similar galactic magnetic dynamo models based on the classic equations and compares them qualitatively to recently observed magnetic fields in edge-on spiral galaxies. We classify the axially symmetric dynamo magnetic field by its separate sources, advected flux, and subscale turbulence. We ignore the diffusion term under plausible physical conditions. There is a time dependence determined by globally conserved quantities. We show that magnetic scale heights increase with radius and wind velocity. We suggest that active galactic nucleus (AGN) outflow is an important element of the large-scale galactic dynamo, based on the dynamo action of increasing subscale vorticity. This leads us to predict a correlation between the morphology of coherent galactic magnetic field (i.e., extended polarized flux) and the presence of an AGN.
A Simulation Study of Ultra-relativistic Jets. II. Structures and Dynamics of FR-II Jets
Authors: Seo Jeongbhin , Kang Hyesung , Ryu Dongsu
Published: October 2021

We study the structures of ultra-relativistic jets injected into the intracluster medium and the associated flow dynamics, such as shocks, velocity shear, and turbulence, through three-dimensional relativistic hydrodynamic (RHD) simulations. To that end, we have developed a high-order accurate RHD code, equipped with a weighted essentially non-oscillatory scheme and a realistic equation of state. Using the code, we explore a set of jet models with the parameters relevant to FR-II radio galaxies. We confirm that the overall jet morphology is primarily determined by the jet power, and the jet-to-background density and pressure ratios play secondary roles. Jets with higher powers propagate faster, resulting in more elongated structures, while those with lower powers produce more extended cocoons. Shear interfaces in the jet are dynamically unstable, and hence, chaotic structures with shocks and turbulence develop. We find that the fraction of the jet-injected energy dissipated through shocks and turbulence is greater in less powerful jets, although the actual amount of the dissipated energy is larger in more powerful jets. In lower power jets, the backflow is dominant in the energy dissipation owing to the broad cocoon filled with shocks and turbulence. In higher power jets, by contrast, both the backflow and jet-spine flow are important for the energy dissipation. Our results imply that different mechanisms, such as diffusive shock acceleration, shear acceleration, and stochastic turbulent acceleration, may be involved in the production of ultra-high energy cosmic rays in FR-II radio galaxies.

The interactions between radio jets and the interstellar medium play a defining role for the coevolution of central supermassive black holes and their host galaxies, but observational constraints on these feedback processes are still very limited at redshifts z > 2. We investigate the radio-loud quasar PSO J352.4034–15.3373 at z ∼ 6 at the edge of the Epoch of Reionization. This quasar is among the most powerful radio emitters and the first one with direct evidence of extended radio jets (∼1.6 kpc) at these high redshifts. We analyze NOrthern Extended Millimeter Array and Atacama Large Millimeter/submillimeter Array millimeter data targeting the CO (6–5) and [C ii] far-infrared (FIR) emission lines, respectively, and the underlying continuum. The broad 440 ± 80 km s−1 and marginally resolved [C ii] emission line yields a systemic redshift of z = 5.832 ± 0.001. Additionally, we report a strong 215 MHz radio continuum detection, 88 ± 7 mJy, using the Giant Metrewave Radio Telescope. This measurement significantly improves the constraints at the low-frequency end of the spectral energy distribution of this quasar. In contrast to what is typically observed in high-redshift radio-quiet quasars, we show that cold dust emission alone cannot reproduce the millimeter continuum measurements. This is evidence that the strong synchrotron emission from the quasar contributes substantially to the emission even at millimeter (FIR in the rest-frame) wavelengths. This quasar is an ideal system to probe the effects of radio jets during the formation of a massive galaxy within the first gigayear of the universe.
Spin Dynamics of Extrasolar Giant Planets in Planet–Planet Scattering
Authors: Hong Yu-Cian , Lai Dong , Lunine Jonathan I. , Nicholson Philip D.
Published: October 2021

Planet–planet scattering best explains the eccentricity distribution of extrasolar giant planets, and past literature showed that the orbits of planets evolve due to planet–planet scattering. This work studies the spin evolution of planets in planet–planet scattering in two-planet systems. Spin can evolve dramatically due to spin–orbit coupling made possible by the evolving spin and orbital precession during the planet–planet scattering phase. The main source of torque to planet spin is the stellar torque, and the planet–planet torque contribution is negligible. As a consequence of the evolution of the spin, planets can end up with appreciable obliquities (the angle between a planet’s own orbit normal and spin axis), with the obliquity distribution peaking at about 10°, and extending to much larger values.
Similar Scale-invariant Behaviors between Soft Gamma-Ray Repeaters and an Extreme Epoch from FRB 121102

Published: October 2021

The recent discovery of a Galactic fast radio burst (FRB) associated with a hard X-ray burst from the soft gamma-ray repeater (SGR) J1935+2154 has established the magnetar origin of at least some FRBs. In this work, we study the statistical properties of soft gamma-ray/hard X-ray bursts from SGRs 1806–20 and J1935+2154 and of radio bursts from the repeating FRB 121102. For SGRs, we show that the probability density functions for the differences of fluences, fluxes, and durations at different times have fat tails with a q-Gaussian form. The q values in the q-Gaussian distributions are approximately steady and independent of the temporal interval scale adopted, implying a scale-invariant structure of SGRs. These features indicate that SGR bursts may be governed by a self-organizing criticality (SOC) process, confirming previous findings. Very recently, 1652 independent bursts from FRB 121102 have been detected by the Five-hundred-meter Aperture Spherical radio Telescope (FAST). Here we also investigate the scale-invariant structure of FRB 121102 based on the latest observations of FAST, and show that FRB 121102 and SGRs share similar statistical properties. Given the bimodal energy distribution of FRB 121102 bursts, we separately explore the scale-invariant behaviors of low- and high-energy bursts of FRB 121102. We find that the q values of low- and high-energy bursts are different, which further strengthens the evidence of the bimodality of the energy distribution. Scale invariance in both the high-energy component of FRB 121102 and SGRs can be well explained within the same physical framework of fractal-diffusive SOC systems.

BACKGROUND: The use of smartphones is increasing in the coronavirus disease (COVID-19) pandemic for various purposes, this encourages smartphone addiction. In addition, the incidence of insomnia has also increased in the pandemic era. AIM: This study was conducted to find an association between smartphone addiction and the incidence of insomnia, especially among students of the Faculty of Medicine, Udayana University. METHOD: This research is a descriptive-analytic study with the cross-sectional method, using two main questionnaires, Smartphone Addiction Scale-Short Version, and Insomnia Severity Index. Questionnaires were distributed using Google forms and then collected and analyzed using software SPSS version 25. RESULT: Overall the total research respondents with the inclusion criteria in this study amounted to 364 people. The results showed that 212 respondents (58.24%) had a high level of smartphone addiction and 152 respondents (41.76%) had a low level of smartphone addiction. In addition, 187 respondents (51.37%) experienced mild insomnia, 87 respondents (23.9%) experienced moderate insomnia, 13 respondents (3.57%) experienced severe insomnia, and 77 respondents (21.15%) did not experience insomnia. Based on the results of data analysis, it was found that smartphone addiction had a significant relationship (p = 0.002) with weak and positive correlation (r = 0.162) to the incidence of insomnia. CONCLUSION: It was found that the majority of respondents experienced high levels of smartphone addiction and mild insomnia. Another finding suggests the higher addiction to the smartphones, the more severe insomnia suffered.
The complete mitogenome of Curculio chinensis (Chevrolat, 1878) (Coleoptera: Curculionidae: Curculioninae)
Authors: Hu Kai , Zhang Nian-nian , Yang Zai-Hua
Published: October 2021

The mitogenome of Curculio chinensis (Chevrolat, 1878) was sequenced and annotated to better identify C. chinensis and related species. The mitogenome is 18,680 bp in length, includes the 37 typical mitochondrial genes (13 protein-coding genes, two ribosomal RNA genes and 22 transfer RNA genes) and two control regions (total length: 3,879 bp). Mitogenome organisation, nucleotide composition and codon usage are similar to the previously sequenced Curculio mitogenomes. All 13 protein-coding genes use ATN or TTG as start codon and end with TAA/G or incomplete stop codons (single T-). Twenty-one transfer RNA genes have the typical clover-leaf structure, while the dihydrouridine (DHU) arm of trnS1 is missing. In Curculio mitogenomes, the size of the control region is highly variable. Both ML and BI analyses, based on the 13 PCGs and two rRNAs from six species of Curculioninae, strongly supported the monophyly of Curculio. In Curculio, the relationships amongst included species were inferred as ((C. chinensis + Curculio. sp.) + (Curculio davidi + Curculio elephas)), with C. chinensis and C. sp. forming a clade (BS = 100; PP = 1).
Covid-19 – ce que la pandémie nous conduit à reconsidérer sur le travail, la décision publique et les relations entre la science et le politique

L’expérience de la pandémie, notamment l’épisode du confinement du printemps 2020 et l’état d’urgence sanitaire, rend plus visible, parmi des questionnements qui lui préexistaient, mais dont l’opinion publique voire les chercheurs n’avaient pas tellement pris la mesure de l’urgence ou de l’importance, les questions suivantes : la valeur sociale d’emplois usuellement considérés comme peu qualifiés et faiblement rémunérés ; le caractère discrétionnaire, plutôt que basé sur des règles, de la décision publique ; les rapports entre la science et le politique, sur des enjeux majeurs que sont les mesures sanitaires et les processus thérapeutiques.
La Recherche et l’Innovation en France

Published: October 2021

L’évolution des missions d’enseignement des universités, le repositionnement de ces dernières dans le système éducatif et leur contribution à la compétitivité, à la capacité d’innovation et à la construction d’une « société de la connaissance » sont aujourd’hui un enjeu politique important. Il se cristallise en partie, au plan européen comme au plan français, autour d’un objectif quantitatif : amener 40 % en Europe, et 50 % en France d’une génération à être diplômés de l’enseignement supérieur. Or cet objectif mérite réflexion sur un plan non seulement quantitatif mais aussi qualitatif. Il n’a véritablement de sens que lié à une dynamique de croissance appuyée sur l’innovation, incitant à « former plus » mais surtout à « former mieux ». Cela est d’autant plus vrai pour le cycle de la licence universitaire, qui devrait être amené, dans le cadre de la réforme licence-master-doctorat (LMD), à occuper dans notre système d’enseignement supérieur un rôle pivot qu’il ne joue pas actuellement pour diverses raisons : logiques des choix des étudiants dans l’éventail des établissements et des formations ; manque de lisibilité de la licence universitaire auprès des diverses parties prenantes ; contenus, méthodes et pédagogies plus ou moins adaptés aux attentes et aux publics diversifiés… La revalorisation de la licence universitaire apparaît du coup comme un enjeu d’avenir d’importance que ce texte analyse dans ses multiples dimensions.
Mobilité de retraite et mobilité post-retraite en Belgique : qui a migré, migrera ?
Authors: Sanderson Jean-Paul
Published: October 2021

Au moment du passage à la retraite, on observe depuis de nombreuses années une mobilité qualifiée de mobilité de « confort ». Les spécificités de cette mobilité ont conduit les chercheurs à s’y intéresser. Depuis quelques années, des travaux menés notamment en France (Thalineau & Nowik, 2009) ont montré l’émergence d’une mobilité en milieu de retraite dont la principale motivation serait de se rapprocher de ses enfants ou de services, les auteurs parlant de « mobilité d’ajustement ». Cet article analyse la situation de la Belgique. Il vérifie l’existence d’une mobilité d’ajustement en Belgique et tente d’en esquisser les contours en analysant notamment l’impact de la réalisation d’une mobilité de confort, lors du passage à la retraite, sur la probabilité d’être mobile en milieu de retraite.
Déménager au cours de la retraite, la recherche d’un équilibre entre idéal et compromis
Authors: Gallou Rémi
Published: October 2021

L’étude des comportements et des pratiques résidentiels constitue un bon moyen d’analyser les transformations sociales, démographiques et politiques. Alors que les aléas liés à la vie professionnelle sont les facteurs importants de la mobilité résidentielle, la retraite des baby-boomers modifie encore plus les causes de mobilité sans en supprimer la complexité ni la diversité. Une typologie de cinq comportements résidentiels a été mise en avant à partir des recherches initiées par le Puca (Plan urbanisme construction architecture) : mobilité résidentielle choisie ; stabilité résidentielle souhaitée ; mobilité contrainte ; assignation à résidence et incertitude résidentielle. La mobilité, lorsqu’elle est réalisée, peut être choisie ou contrainte ; elle peut également être souhaitée, sans être concrétisée. Le classement des causes de déménagement en grands thèmes (famille, logement, santé, économie, etc.), pour pratique qu’il soit, n’est pas pleinement satisfaisant, car il ne restitue pas la complexité des mécanismes qui sous-tendent la mobilité résidentielle. L’enquête Amare vise à saisir les choix et les contraintes s’imposant aux ménages, et plus généralement les fonctionnements complexes et évolutifs des trajectoires résidentielles selon les générations. Dans ce cadre, cet article étudie les tensions qui existent entre choix et contrainte dans les arbitrages mis en œuvre par les retraités interrogés, rencontrés dans les deux ans suivant leur déménagement. Dans un premier temps, il examine les cas où la mobilité s’est réalisée sous la pression d’un événement, sans oblitérer totalement la marge de choix. Dans un second temps, l’article est consacré aux situations de maîtrise de la mobilité, dont l’objectif est de renforcer un positionnement social.
Mobilités résidentielles des retraités français au Maroc : entre choix hédonistes et enjeux familiaux
Authors: Pinel Jordan
Published: October 2021

À partir d’une enquête de terrain menée dans le Souss-Massa (Maroc) entre 2017 et 2020, cet article analyse les logiques résidentielles et familiales de retraités français installés au Maroc tout ou partie de l’année. Alors que les motivations qui sous-tendent ces installations à l’étranger révèlent souvent des logiques hédonistes liées au climat, au coût de la vie et aux aménités proposées sur le territoire marocain, les pratiques résidentielles de ces retraités s’avèrent aussi prendre en compte la famille restée en France, qu’il s’agisse de la forme des installations, des allers-retours réguliers effectués entre les deux pays, du choix du lieu de vie ou encore celui du logement. L’espace résidentiel établi dans un cadre international relève donc de stratégies résidentielles particulières pour conserver et entretenir les liens familiaux. Ainsi, les lieux de vie et le fonctionnement des membres de la famille continuent d’influencer les choix résidentiels au moment de la retraite.
Mobilité résidentielle en résidence autonomie : quelles reconfigurations des relations sociales et familiales ?
Authors: Simzac Anne-Bérénice
Published: October 2021

La résidence autonomie est un établissement médico-social accueillant des personnes de plus de 60 ans autonomes, c’est-à-dire pouvant accomplir les tâches de la vie quotidienne et ne présentant pas de trouble cognitif particulier. L’entrée dans ce type de structure constitue une nouvelle étape du parcours résidentiel et implique ainsi de nombreux changements pour les personnes âgées, mais aussi pour leur entourage. Cet article interroge plus spécifiquement l’influence de l’emménagement en résidence autonomie sur les relations sociales et familiales des résidents. Nous proposons ici d’analyser la place de l’entourage des résidents au moment de l’entrée et de la sortie de l’établissement. Nous nous interrogerons également sur le fait d’habiter quasi exclusivement avec des personnes de plus de 60 ans. Ces habitats sont-ils ségrégatifs ? Sont-ils perçus de la sorte par les résidents eux-mêmes ? Nous traiterons enfin de la mobilité de sortie de la résidence autonomie. Est-ce une mobilité souhaitée par les résidents, et quels sont les impacts des liens sociaux et familiaux sur cette mobilité ? Cette enquête relève que la mobilité résidentielle n’est pas sans effet sur les relations sociales et familiales, mais aussi que l’entourage des résidents se trouve directement impliqué dans le processus. Ainsi, paradoxalement, malgré une forte volonté d’indépendance des résidents vis-à-vis de leurs proches, l’entourage est mobilisé lors de l’entrée en résidence autonomie, mais également lors de la sortie. Les matériaux mobilisés ici sont issus de données qualitatives recueillies pour une thèse soutenue en 2016.
Crisis risk prediction with concavity from Polymodel
Authors: Kuang Yao , Douady Raphael
Published: October 2021

Financial crises are an important research topic because of their impact on the economy, businesses, and populations. However, prior research tends to generate reactive systemic risk measures, in the sense that the measure surges after the crisis starts. Few of them succeed in warning of financial crises in advance. In this paper, we first sketch a toy model that produces normal mixture distributions based on a dynamic regime switching model. We derive that the relative concavity among various indices tends to increase before a crisis. Using Polymodel theory, we introduce a measure of concavity as a crisis risk indicator, and test it against known crises observed in the past. We validate this indicator by a trading strategy holding long or short positions on the S & P 500 Index, depending on the indicator value.

Published: October 2021

In 5G applications, this paper proposes a single-band four-antenna array for faster velocity and single output (MISO) mechanisms. There were also separate based on step-impedance resonators, L-shaped slot antennas in the established MISO antenna array stepped impedance resonator (SIRs). By calculating the SIR's impedance ratio, the proper single-resonance can be obtained, and for each component in the antenna. By tuning the alignment of the antenna's micro strip antenna app, good impedance matching can be assumed. A decided return loss of more than 10 dB and a measured inter-element isolation of greater than 10.2 dB are illustrated by the experimental results were obtained over the long-term evolution (LTE) band 52 (3358-3640 MHz) and LTE band 20 20 with a simulated cost efficiency of well over 61 percent for each antenna line (5250-5985 MHz). Besides that, between arbitrary two antenna pieces, the decided envelope correlation the coefficient (ECC) is higher than 0.2, and the proposed MISO antenna array achieves a simulated channel capacity of more than 42.5 bps/Hz within both transmission bands. Absolute anthropomorphic mannequins (SAM) in the head and human brain in the presence of, in particular, the MISO antenna array can ensure adequate radiation and MISO accuracy.

The functional aspect of nanotechnology (NBT) is driven either to accelerate the performance of materials and/or to reduce the quantity of materials that are used for the purpose. Most significantly, its potential attribute to the environment includes the treatment and remediation, sensing and detection, and pollution prevention. In general nano-bio remediation (NBR) involves the use of nano-materials either in in-situ (in place), or ex-situ (off-place) treatment of contaminated materials. To accomplish this, the elemental or zero-valent metals and like materials in nano-form (1-100 nm) have been applied as an instinctive need to embrace sustainable environment. The use of nanomaterials initially reduces the biodegradable contaminants and then it promotes to achieve the standard levels. Thus, the role of nano-materials could be an efficient, effective approach to remediate the environmental contaminant sustainably. However, further research is required to record the detailed fate of the nano-materials that are used in environment remediation.

Soil pollution is rising rapidly due to the existence of pollutants or natural alterations in the soil. It makes the drinking water ineffective and unusable by the human beings. The major cause of the soil contamination is agricultural activities, industrial activities, and inadmissible disposal of waste in the soil. The most common pollutants to accumulate in the soil are petroleum hydrocarbons, solvents, pesticides, lead, and other heavy metals. The important technology to remediate the pollutants or contaminants in the soil is bioremediation. The utilization of bioremediation in the contaminated soil is increasing rapidly due to the presence of toxic pollutants. It is the most advanced technologies which make use of organisms to deteriorate the harmful compounds in order to prevent the soil pollution. The aim of the chapter is to describe the available bioremediation technologies and their application in removing the pollutants exist in the soil.
Metal Hyperaccumulator Plants and Environmental Pollution

Published: October 2021

During evolutionary history of life on Earth, different life forms have undergone harsh environmental conditions. Plants have evolved multiple life forms and some of the specialist pioneer plants have the ability to colonize in hostile environmental conditions. Some plant taxa have the ability to accumulate high concentrations of potentially toxic trace elements (Ni, Zn, Cd, Se, As, Mn, Co, Cu, Pb, Sb, Tl) in their biomass. In some of these, taxa concentration of trace elements exceeds the concentration of macronutrients (e.g., Ca, K). Furthermore, metal hyperaccumulation is strongly associated with enhanced ability of these plants to detoxify the accumulated metal in the tissues. Such hyperaccumulation property has been reported in a total of approximately 500 Angiosperm species. This ability of the plants can be used for pollutant stabilization, extraction, degradation, or volatilization. The present chapter discusses heavy metals uptake mechanisms by plants and the potential of phytoremediation technique on treating heavy metal contaminated sides.

Authors: Tugushev Anton
Published: October 2021

The chapter attempts to generalize and categorize the most common factors affecting SEZ performance globally. The effectiveness of SEZ functioning depends on its type and a variety of internal and external factors. These factors have different nature, importance, and scale of severity of influence. Many academic papers focus only on tax, foreign trade, and administrative incentives in SEZ. However, the general factors connected with country's investment climate, geographical location of SEZ, and other factors are not least influential. Thus, the chapter aims at identifying a system of main factors of different nature affecting SEZ performance.

Shenzhen's emergence as one of China's first SEZ has come to serve broader socio-economic implications. The successful transition to a socialist market economy under Deng Xiaoping has since then seen the SEZ operating at a global scale in which other regions would later come to emulate. Through this zone, the development of this space for large-scale commercial and industrial activity would come to envelop an expansive influence capable of shaking up the global political economy. As the country modernized at an unprecedented rate, Shenzhen entered the stage of the technologically-focused. Facing pressure to conform to global standards, the city's current position as a hub for emerging innovations would face intense scrutiny as the country battles to uphold its responsibilities as a global power. Here, the authors discuss how the development of Shenzhen's SEZ from its initial inception has contributed towards in reforming and setting a successful model of standards for other regions. They delve into the SEZ has contributed in reducing pressing social disparities within the country.

Published: October 2021

Graduate students and novice researchers can face scientific worldview-related stereotypes, stigmatization, and disruptive tensions during mixed methods research meetings. To avoid such difficulties, there is a need to better understand how to use and combine several worldviews in the same mixed methods study. Yet, little is known on ‘how to' combine worldviews. In this chapter, the authors report their literature review of key reference texts and a sample of mixed methods empirical studies. Key findings show five common contemporary worldviews (postpositivism, social constructivism, pragmatism, critical theory, and critical realism) and six possible combinations of worldviews in mixed methods studies: three combinations without integration (a-paradigmatic, substantive theory, and single worldview) and three combinations with integration (multiple worldviews, complementary strengths, and dialectical pluralism). This led to propose a framework and aid for combining worldviews to help team members to prevent and manage worldview-related disruptive tensions in their mixed methods projects.
Application of the Convergent Mixed Methods Research Design in the Study of Email Records Management in Zimbabwe's Central Government
Authors: Mutsagondo Samson
Published: October 2021

Mixed methods research, the so called “third methodological movement,” has come as a great relief to scholars who do not subscribe to the polarised qualitative and quantitative research approaches alone. It has plugged the gap between the two approaches and has capitalised on the strengths of the two as well. In fact, it tells a complete story from both ends, thus adding and aiding comprehension and comprehensiveness at the same time. Many researchers have had difficulties in correctly using and applying the mixed methods research approach. Through use of the convergent mixed methods research design, the chapter helps to show why, how, and where quantitative and qualitative elements can be correctly and effectively mixed in pursuit of assessing email management strategies and the importance thereof in Zimbabwe's central government.
Strain Engineering of Graphene Nanoribbon Transistors Made Using Analytical Quasi-Ballistic Transport Model
Authors: Kliros George
Published: October 2021

In this work, the impact of uniaxial strain on the current-voltage characteristics and the key performance metrics of armchair graphene nanoribbon (AGNR) field-effect transistors (FETs) are thoroughly studied by means of an analytical quasi-ballistic transport model that incorporates the effects of hydrogen passivation and third nearest-neighbor interactions. The model leads to compact expressions for the current-voltage characteristics of the device with only two fitting parameters and is verified by atomistic quantum simulations. The values of these parameters should be changed fromdevice to device. The obtained results reveal the tunable nature of the performance metrics of AGNRFETs with the application of tensile strain. Gate capacitance, cutoff frequency, on/off drain-current ratio, intrinsic delay and power-delay product under strain applied to the three distinct families ofAGNRs, are evaluated. This study can offer useful insight and guidance for strain engineering of GNR-based FETs.
