Published: December 2020

Consider an essentially nonbranching metric measure space with the measure contraction property of Ohta and Sturm, or with a Ricci curvature lower bound in the sense of Lott, Sturm and Villani. We prove a sharp upper bound on the inscribed radius of any subset whose boundary has a suitably signed lower bound on its generalized mean curvature. This provides a nonsmooth analog to a result of Kasue (1983) and Li (2014). We prove a stability statement concerning such bounds and - in the Riemannian curvature-dimension (RCD) setting - characterize the cases of equality.
Radiative Supernova Remnants and Supernova Feedback
Authors: Koo Bon-Chul , Kim Chang-Goo , Park Sangwook , Ostriker Eve C.
Published: December 2020

Supernova (SN) explosions are a major feedback mechanism, regulating star formation in galaxies through their momentum input. We review the observations of SNRs in radiative stages in the Milky Way, to validate theoretical results regarding the momentum/energy injection from a single SN explosion. For seven supernova remnants (SNRs) where we can observe fast-expanding, atomic radiative shells, we show that the shell momentum inferred from H i 21 cm line observations is in the range of (0.5–4.5) × 105
M
⊙ km s−1. In two SNRs (W44 and IC 443), shocked molecular gas with momentum comparable to that of the atomic SNR shells has also been observed. We compare the momentum and kinetic/thermal energy of these seven SNRs with the results from 1D and 3D numerical simulations. The observation-based momentum and kinetic energy agree well with the expected momentum/energy input from an SN explosion of ∼1051 erg. It is much more difficult to use data/model comparisons of thermal energy to constrain the initial explosion energy, however, due to rapid cooling and complex physics at the hot/cool interface in radiative SNRs. We discuss the observational and theoretical uncertainties of these global parameters and explosion energy estimates for SNRs in complex environments.
AREPO-MCRT: Monte Carlo Radiation Hydrodynamics on a Moving Mesh
Authors: Smith Aaron , Kannan Rahul , Tsang Benny T.-H. , Vogelsberger Mark , Pakmor Rüdiger
Published: December 2020

We present arepo-mcrt, a novel Monte Carlo radiative transfer radiation-hydrodynamics (RHD) solver for the unstructured moving-mesh code arepo. Our method is designed for general multiple scattering problems in both optically thin and thick conditions. We incorporate numerous efficiency improvements and noise reduction schemes to help overcome efficiency barriers that typically inhibit convergence. These include continuous absorption and energy deposition, photon weighting and luminosity boosting, local packet merging and splitting, path-based statistical estimators, conservative (face-centered) momentum coupling, adaptive convergence between time steps, implicit Monte Carlo algorithms for thermal emission, and discrete-diffusion Monte Carlo techniques for unresolved scattering, including a novel advection scheme. We primarily focus on the unique aspects of our implementation and discussions of the advantages and drawbacks of our methods in various astrophysical contexts. Finally, we consider several test applications including the levitation of an optically thick layer of gas by trapped infrared radiation. We find that the initial acceleration phase and revitalized second wind are connected via self-regulation of the RHD coupling, such that the RHD method accuracy and simulation resolution each leave important imprints on the long-term behavior of the gas.
Snakes of the Pernambuco Endemism Center, Brazil: diversity, natural history and conservation
Authors: França Rafaela C. , Morais Mayara , França Frederico G. R. , Rödder Dennis , Solé Mirco
Published: December 2020

The Atlantic Forest is one of the largest and richest tropical rainforests on the planet, being one of the 25 world priorities for conservation. The Atlantic Forest portion located north of the São Francisco River corresponds to the Pernambuco Endemism Center (PEC). We describe the snake composition of the PEC, providing information about the diversity, natural history and geographical distribution of the species, based on records from five scientific collections and additional information from the literature. A total of 78 species of snakes distributed in eight families was registered in the Pernambuco Endemism Center. The Caatinga is the Brazilian biome that most shares species with the PEC, followed by Cerrado. On the other hand, seven species are considered endemic of this region. Most of the snake species in the PEC have been registered in forest (94.8%), followed by “Brejos Nordestinos” (46.1%), Tabuleiros (43.5%), Restingas (14.1%) and Mangroves (5.1%). The PEC snake fauna includes mainly terrestrial species (60.2%) and cryptozoic and/or fossorial species (21.7%), but also presents a high richness of semi-arboreal and arboreal species (29.5%). Vertebrates are the main food item consumed by the species (78% of species), among the main prey are mammals, lizards, and amphibians. Most species show a strictly nocturnal activity period (50%), followed by strictly diurnal (38%). The PEC is the most degraded and least known region of the Atlantic Forest, yet it has revealed a high richness of snake species, including seven endemic species. It is emphasized that regional conservation efforts need to be intensified, because few forests in the region are formally protected, and the majority consist of small and poorly protected fragments, which means that many species in the region may be in risk of extinction.
La chefferie traditionnelle à l’épreuve des mutations et compétitions politiques en Côte d’Ivoire : cas de Kéibly dans la sous-préfecture de Bloléquin en pays Wê
Authors: Mahier Bah Michel Jules , Koffi Eben-Ezer César Léonce , Gade Charles Sylvain
Published: December 2020

Dans les sociétés rurales Wê situées à l’ouest de la Côte d’Ivoire, le dispositif de renouvellement de la chefferie connaît ces dernières années des mutations inédites qui consacrent l’effritement du mode de désignation consensuelle au profit du mode électoral. L’objectif de cette étude est d’en analyser les enjeux. Les données recueillies à l’aide de la méthode qualitative sont analysées dans une perspective systémique. La tendance qui se dégage montre que la transformation des modes de désignation dans la gouvernance locale qui sont passés du mode consensuel à l’électif sous l’influence combinée de facteurs multiples est davantage liée à l’immixtion d’acteurs politiques, dont la logique d’action consiste en la maîtrise de l’espace villageois dans la perspective des compétitions électorales locales ou nationales.
Loneliness in Homeless Participants of a Housing First Program: Outcomes of a Randomized Controlled Trial
Authors: Ferreiro Inés Campo , Abad Josep Maria Haro , Cuadra Maria Assumpta Rigol
Published: December 2020

People who are homeless are likely to experience loneliness. Housing First (HF) is a program aimed at providing home placement to homeless people who also have mental health and/or substance use–related problems. The current study was performed to assess feelings of loneliness among participants of a HF program. A randomized controlled trial was performed comparing participants in two groups, HF (
n
= 46) and treatment as usual (
n
= 41). No significant differences regarding loneliness between groups were noted at baseline (
p
= 0.841), 8-month follow up (
p
= 0.509), or 21-month follow up (
p
= 0.833); however, participants with severe mental illness reported higher feelings of loneliness at the 8-month assessment than at baseline. This increase was higher in HF participants. These findings are partially consistent with previous research and are of relevance for providers, policy makers, and teams working with HF programs. Findings indicate the need to address feelings of loneliness in this population. Further research is needed to ascertain the effectiveness of HF programs on loneliness. [

Children of Parents With Opioid Use Disorder
Authors: Ahern Nancy R. , Mechling Brandy , Palumbo Ruthanne , Woodard Elizabeth
Published: December 2020

Substance use disorders (SUDs) have been a priority public health concern for decades, with most recent conversations focusing on the opioid use disorder (OUD) epidemic. Children of parents with OUD have been impacted through poverty, violence, neglect, and emotional and physical abuse. Although treatment programs may address the family and parental role, few focus on the children. Without building resiliency in a child's mental and physical health, the far-reaching impact of the opioid epidemic will continue. The goal of the current literature review was to critique available intervention programs that focus on children of parents with SUD/OUD and provide recommendations for best practice. A literature search found six child-focused intervention programs dated in the 1990s and early 2000s and generalized to parents with SUDs. No intervention was found specific to children of parents with OUD. Nurses and other health professionals can use these findings to determine which evidence-based intervention is most appropriate for the needs of this specific population. [

Energy method for exponential stability of coupled one-dimensional hyperbolic PDE-ODE systems
Authors: Angeles Gervy Marie , Peralta Gilbert
Published: December 2020

We consider a hyperbolic system of partial differential equations on a bounded interval coupled with ordinary differential equations on both ends. The evolution is governed by linear balance laws, which we treat with semigroup and time-space methods. Our goal is to establish the exponential stability in the natural state space by utilizing the stability with respect to the first-order energy of the system. Derivation of a priori estimates plays a crucial role in obtaining energy and dissipation functionals. The theory is then applied to specific physical models.
EFFECT OF STYRENE-BUTADIENE COPOLYMER (SBR) LATEX ON MECHANICAL AND TRANSPORT PROPERTIES OF PORTLAND CEMENT MORTAR

Published: December 2020

Portland cement is extensively used as a binder in concrete production. However, with Portland cement production, 5% of the natural resources used in this production are consumed, constituting 5–7% of the total CO2 emission. In order to mitigate the environmental problems associated with cement production, styrene-butadiene rubber latex was used as cement replacement up to 20%. In this study, compressive strength, flexural strength, unit weight, water absorption, open porosity, water sorptivity and the chloride ion permeability of Portland cement mortar mixtures modified by styrene-butadiene rubber (SBR) polymeric latex were investigated. For this purpose, the sand/cement ratio and the water/cement ratio were kept constant as 3/1 and 0.5, respectively. In addition to the control mixture containing no polymer, 1, 2, 3, 5, 10 and 20 wt.% of cement was replaced with SBR. In this way, seven mortar mixtures were prepared. Mixed curing (wet cure and dry cure) method was applied to the mortar specimens. Results showed that up to a 5% replacement level, it is possible to improve the mechanical properties of cement mortars with SBR latex addition. However, at a 10% and 20% replacement level, SBR had a significant detrimental effect on the mechanical properties of polymer modified mortars. However, the transport properties decreased with the incorporation rate of SBR latex and the detrimental effect of SBR replacement was more pronounced in 20% SBR mortar mixtures.
A ROADMAP FOR BUILDING CLIMATE RESILIENCE AT HIGHER EDUCATION INSTITUTIONS: A CASE STUDY OF ARIZONA STATE UNIVERSITY
Authors: Campbell Hailey , Crippen Alise , Hawkey Corey , Dalrymple Mick
Published: December 2020

Over the past few years, more and more higher education institutions have pledged to achieve carbon neutrality and designed and adopted Climate Action Plans. Although many higher institutions are adopting climate action plans, few are integrating resilience principles and priorities, which are essential for understanding institutions’ adaptive capacity for dealing with climate change. There is little existing research on how higher education institutions can implement climate resilience programs, behaviors, and policies into their planning process and campus-communities. To address this gap, this case study explores Arizona State University’s process of designing and implementing a climate resilience plan and outlines best practices other higher education institutions can utilize to create their own climate resilience plan. We critically discuss the importance of climate resilience at the higher education level, outline steps necessary for designing an inclusive and holistic climate resilience plan, and provide examples of important techniques used to design the climate resilience plan.
ENERGY EMBODIED IN, AND TRANSMITTED THROUGH, WALLS OF DIFFERENT TYPES WHEN ACCOUNTING FOR THE DYNAMIC EFFECTS OF THERMAL MASS
Authors: Reilly Aidan , Kinnane Oliver , O’Hegarty Richard
Published: December 2020

Embodied energy is a measure of the energy used in producing, transporting and assembling the materials for a building. Operational energy is the energy used to moderate the indoor environment to make it functional or comfortable—primarily, to heat or cool the building. For many building geometries, the walls make the most significant contribution to the embodied energy of the building, and they are also the path of greatest heat loss or gain through the fabric, as they often have a greater surface area than the roof or floor. Adding insulation reduces the heat flow through the wall, reducing the energy used during operation, but this adds to the embodied energy. The operational energy is not only a function of the wall buildup, but also depends on the climate, occupancy pattern, and heating strategy, making an optimisation for minimum overall energy use non-trivial. This study presents a comparison of typical wall construction types and heating strategies in a temperate maritime climate. The transient energy ratio method is a means to abstract the heat flow through the walls (operational energy for heating), allowing assessment of the influence of walls in isolation (i.e. in a general sense, without being restricted to particular building geometries). Three retrofit scenarios for a solid wall are considered. At very low U-values, overall energy use can increase as the embodied energy can exceed the operational energy; current best practice walls coupled with low building lifetimes mean that this point may be reached in the near future. Substantial uncertainty is present in existing embodied energy data, and given its contribution to total energy use, this is a topic of urgent concern.
Les décembristes

« Nous réclamons une constitution. • Telle est l’exhortation qu’une centaine d’officiers, rassemblés sur la place du Sénat à Saint-Pétersbourg le 14 décembre 1825, adresse à Nicolas 1er. La réponse du jeune empereur est à l’image de l’autocratie : arrestation, procès, puis condamnation à l’exil. Le destin des insurgés se poursuit en Sibérie : portant le nom de leur insurrection, les « décembristes » sont déportés pour avoir élevé la contestation en place publique.

Comment des officiers, loyaux soutiens de l’Empire, ont-ils pu prendre les armes contre leur souverain ? Le présent ouvrage se donne l’ambition de retracer l’itinéraire de ces hommes pour comprendre leur marche vers l’insurrection de 1825. Il s’appuie sur un corpus original et varié : archives familiales, correspondances, projets de constitution, interrogatoires et dossiers d’instruction, mémoires rédigés en exil. Ces sources nous dévoilent l’intimité d’une génération, née en terre d’autocratie, devenue républicaine.
L’impossible alliance ?
Authors: Sanderson Claire
Published: December 2020

Alliées et rivales, entre entente et mésentente, la France et la Grande- Bretagne ont, dès la fin de la Seconde Guerre mondiale, une perception différente des principes de la mise en œuvre d’une politique de sécurité commune en Europe. De l’immédiat après-guerre à l’arrivée du général de Gaulle en 1958, cet ouvrage explique les divergences du couple franco-britannique sur la question de la défense de l’Europe occidentale. Tandis que la France se situe dans un contexte de construction européenne, la Grande- Bretagne, prenant progressivement conscience de l’effritement de son statut de grande puissance, privilégie la mise en œuvre de cette défense européenne dans un cadre de plus en plus atlantique. L’analyse des archives diplomatiques françaises et britanniques éclaire d’un jour nouveau la part de la responsabilité britannique dans l’échec de la Communauté européenne de défense, et les priorités divergentes de la Grande-Bretagne et de son voisin français. Du lendemain de la guerre aux nouvelles donnes stratégiques européennes apparues après la dissolution du bloc soviétique, les relations franco-britanniques ont traversé plusieurs décennies d’incompréhension mutuelle. Période charnière au cours de laquelle se dégagent les priorités en matière de défense européenne, les années 1945-1958 offrent un champ de recherche permettant d’identifier et d’analyser les racines de cette incompréhension.
Les ingénieurs des travaux publics et la transformation des métropoles américaines, 1870-1910
Authors: Harter Hélène
Published: December 2020

À la fin du XIXe siècle au moment où la Révolution industrielle fait des États-Unis un pays tourné vers le progrès industriel et technique, un nouvel acteur s'impose sur la scène urbaine : l'ingénieur des travaux publics. Grâce aux équipements qu’il réalise, les métropoles se transforment radicalement. La modernisation des réseaux d’eau et des égouts fait reculer les épidémies, la création d'espaces verts améliore le cadre de vie, tandis que la construction d'ouvrages d'art, comme le pont de Brooklyn à New York, facilite la circulation. L'aptitude à l’innovation des ingénieurs municipaux américains est telle qu'ils deviennent des références en matière de travaux publics, en Amérique, mais aussi en Europe. S'intéresser à leur œuvre permet donc de mieux comprendre comment les États-Unis devienne à la fin du XIXe siècle une puissance technique de premier plan. L'influence de ces ingénieurs ne se limite pas cependant aux seules questions techniques. En effet, en recrutant ces hommes, les métropoles américaines posent les bases d'un gouvernement par l'expertise qui sera largement plébiscité au XXe siècle. On est loin de l'image corrompue qui est généralement associée aux villes à celle époque. En analysant le rôle des ingénieurs municipaux, c'est en fait les réalités urbaines de la fin du XIXe siècle que nous cernons mieux.
Le péronisme
Authors: Guillerm Gérard
Published: December 2020

Argentine, 1955-1989 : environ trente cinq ans d’histoire, au travers de la propre histoire de ce mouvement politique - le Péronisme - qui malgré (ou en raison) de ses multiples avatars, demeure la force incontournable sans laquelle l’avenir argentin ne peut sérieusement être envisagé. L’auteur tente ici cette gageur de restituer, avec rigueur, honnêteté et en refusant les a-priori, les principaux épisodes et faits marquants de cette histoire : le rôle de cette figure mythique que fut Evita ; le coup d’Etat de septembre 1955 contre Peron ; l’essai de John William Cooke de créer un grand mouvement de résistance à la Junte militaire ; le pacte Peron-Frondizi ; le « jeu » entre le général Lanusse et l’exilé de Madrid ; l’échec de la tentative d’instaurer, sous Hector Campora, un « Péronisme socialiste » ; la Présidence de la troisième épouse, Isabelita, dominée par le personnage raspoutinien Lopez Rega ; le désastre du régime militaire après le coup d’Etat de 1976 ; la guerre des Malouines ; le rétablissement de la démocratie avec l’élection d’Alfonsin ; le grave échec économique du gouvernement radical. Ce livre, en définitive, n’a d’autre ambition (car il s’agit d’une « chronique ») que d’apporter sa contribution à une meilleure connaissance d’un mouvement politique qui a toujours fortement oscillé entre ses extrêmes, et qui cherche, aujourd’hui, à occuper une position « centrale » sur l’échiquier politique argentin. Le Péronisme aurait pu donner le meilleur. Il a parfois le pire. Peut-il, à présent, apporter à l’Argentine ce dont elle a besoin : un peu plus que l’« acceptable » ? Et demain, sera-t-il capable de promouvoir cet « humanisme tempéré » que mérite l’Argentine et dont parle Tzvetan Todorov dans son livre « Nous et les autres » ? En définitive, réussira-t-il à « dépasser » Peron ? Cette question, pour l’instant, ne peut rester que sans réponse.

Performance Evaluation of 5G/WiFi-6 Coexistence
Authors: Zreikat Aymen
Published: December 2020

The fifth-generation mobile communication network (5G) is the promising technology nowadays to provide not only a higher speed compared to 4G but also a revolution of services to cover different industrial sectors such as health, production, energy, and many. WiFi-6 is a new wireless local area network (WLAN) technology that is suitable to work in an office, home, and dense areas. As a new technology, 5G has some limitations concerning coverage and capacity. To overcome these limitations, one possible solution is to use the free unlicensed spectrum available in Wi-Fi technology, therefore, a complement solution of 5G/WiFi-6 coexistence is proposed to make both technologies complement each other in providing a better quality of service for the end-user concerning a higher speed, low latency, and higher capacity. According to OFDM modulation, the proposed model divides the cell into two virtual zones, the inner zone represents WiFi-6 technology surrounded by 5G technology. All resources will be shared between the two technologies taken into consideration that more bandwidth should be given to the most inner zone with high intensity of traffic. The call admission control algorithm will be based on a minimum bit rate to be given to each zone that should be satisfied to admit the call. The model is solved using MOSEL-2 simulation language, to study different performance parameters such as BER, utilization, blocking probability, latency, throughput, and aggregate average bit rate in both zones. The simulation results show that coexistence causes some degradation in 5G performance, however, a positive effect on the overall cell performance is achieved by balancing the load all over the whole cell.

Published: December 2020

This study developed an automated machine that automatically controls the feeding routine of fish by checking four parameters that will serve as a prerequisite before dispensing the required amount of commercial feeds. The parameters to be checked are time, precipitation, the water temperature of the pond, and behavior of the fishes. The machine is also capable of notifying the owner or caretaker via text message if fishes have been fed successfully or not and if the level of the feeds is low. The machine utilizes sensors, namely a raindrop sensor, temperature sensor, and water flow sensor in which data are gathered through the aid of a microcontroller. After undergoing several trials, it was revealed that the fish feeding machine was able to implement the capabilities of the manual process of feeding done by a fish farmer. It also dispensed the required weight of feeds on time after satisfying the parameters. The machine was also reliable in terms of sending notifications to the owner through text message since results convey that they were received within 10 seconds if the signal is fine.

A motorized, manual fed cassava root chipping machine was
developed, evaluated and optimized. The objective of the research is
to investigate the effect of moisture content and speed on the chipping
sizes, efficiency, throughput and machine capacities. Obtained results
showed that the cassava initial moisture content significantly affected
the chipping size, machine capacity, throughput capacity and
chipping efficiency within the tested moisture content range of 52 to
68% w.b. The machine speed also affected the chipping size, chipping
efficiency, machine and throughput capacity. The average chipping
size for the cassava chips at the four ranges of moisture content,
speeds and constant feed rate of 89±26.6 kg h-1 ranged from 0.56 to
0.96 cm with optimum thickness 0.618 at 450 rpm and moisture
content of 65.27% based on desirability factor. The average chipping
efficiency ranged from 60 to 90% with an optimum value of 79.57% at
533 rpm and moisture content of 68 % while the throughput capacities
of the machine ranged from 49 to118 kg/h with optimum value of 118
kg/h at a speed of 600 rpm and 68% moisture content.
Yield Estimation of Winter Wheat in Pre-harvest Season by Satellite Imagery Based Regression Models
Authors: UNAL Ediz , YILDIZ Hakan , MERMER Ali , AYDOGDU Metin
Published: December 2020

Early crop yield estimates could provide up-to-date information
on supply, demand, stocks, and export availability through
which governing bodies can make better agricultural
management plans. This study aims to develop a yield model
estimating pre-harvest winter wheat yield at both tillering and
flowering stages using a multiple linear regression approach
based on the relationship between actual yield and satellite
derived crops’ phenological parameters. Four crop parameters
(NDVI, Cumulative NDVI, LAI and FPAR) were regressed in
combination to find the best applicable model. Regression results
showed that correlations for all models among the variables of
the flowering period are higher than that of tillering (0.63>0.53).
The mean RMSE’s of the observed vs predicted yields for
tillering period was 645.9 kg ha-1 and 574.5 kg ha-1 for flowering
period. The optimal developed model which consists of NDVI and
CNDVI variables provided 76% and 79% of predicting accuracy
3 and 1.5 months before harvest respectively.

Pharmacological management of vomiting in feline patients – a review
Authors: Merlo Alexandre
Published: December 2020

Vomiting is a complex protective reflex mediated by the emetic center, a region of the central nervous system that receives impulses from other central and peripheral afferent areas. In cats, substance P, serotonin and norepinephrine are the main mediators of vomiting, with histamine, dopamine, acetylcholine, and enkephalins having a secondary role. In view of variations in the physiology of vomiting and pharmacology across species, the importance of studies focused on felines is emphasized. Among the emetic agents, alpha-2-adrenergic agonists, such as dexmedetomidine and xylazine, are the most studied in the species for this purpose. Maropitant and ondansetron are the more recent antiemetic drugs. Mirtazapine may be useful to prevent chronic vomiting.

Kindergarten (TK) or Raudatul Atfal (RA) children are generally very active, they have mastery over their bodies and really like doing activities on their own. Therefore, parents or teachers need to provide space and time for children to do activities that can train the child's gross muscles as well as provide items and equipment for children that can be pushed, lifted, thrown or carried. Teachers must also be creative in seeing learning models that can attract children's interest in learning.

Traditional games are a wealth of the Indonesian nation. One of these types of traditional games, namely sondah gunung or crank, is a favorite game for children because it can be played by boys or girls. In the crank game there is a value for good physical development which is reflected in the crank game which requires whole body movements, namely lifting one leg, moving the body and hands. By doing these activities, it means that the child has carried out activities for sports, especially in gross motor movements, namely throwing, jumping, jumping, and standing on one leg. Apart from that, the mountain skating game can improve coordination and body balance and develop children's skills. All of which aim to help the child's growth.

The implementation of gross motor learning activities for children aged 4-5 years with the traditional game of sondah gunung (crank) at RA Miftahul Jannah, Bogor City that has been implemented can significantly improve children's motor skills. The research was conducted with 1 pre-research activity and 2 research cycles with a total of 7 meetings. This is evidenced by an increase in the average in each assessment, namely in the pre-test the average motoric ability of children is 47.36%, then in cycle 1 it is 71.23% and in cycle 2 it is 86.54%. The average percentage increase from pretest to posttest in cycle 1 was 23.85%. The percentage of average increase from posttest in cycle 1 to posttest cycle 2 was 15.21%. So the average percentage increase from pretest to posttest cycle 2 is (23, 85% + 15, 21%) = 39, 06%.

The role of legal noospherology in the development of scientific methods of international legal forecasting
Authors: Баймуратов Михайло Олександрович , Ожерельев Володимир Петрович
Published: December 2020

In 2019, in the scientific and practical legal journal "Public Law" №1 (33), the authors published an article on the feasibility of developing a single model of international public law and the noosphere. This decision was made in accordance with known scientific facts: the existence of a single global space of civilizational events and the noosphere, the space of which can be represented as a topological, and the system of public international law can be described as an "equilibrium surface" of differentiated diversity. The development of these studies led the authors to the realization of the existence of a global information and legal structure in the noosphere system, and then to the development and creation of a "topological double-circuit shell-nuclear information and legal model of the noosphere." This model became a conceptual basis for further research: to develop a system of noosphere law, methods of international legal forecasting and monitoring the "stability" of the information and legal structure of the civilizational space of the noosphere. The results of the research are the theoretical foundation for the formation and development of a new scientific and educational interdisciplinary discipline: "legal noospherology", which is of paramount scientific importance for the development of effective methods of international legal forecasting.

Published: December 2020

This paper examines the impact of teleworking on employees’ labour productivity and the entity`s management in the condition of global pandemic Covid-19 in Uzbekistan. The epidemiological and dynamic nature of the Covid-19 crisis in which organizations have to adopt a work-from-home policy made this investigation very necessary. When the issue is explained more broadly, this empirical research investigates two significant aspects about teleworking process in organizations in the period of lockdown in Uzbekistan. First, teleworking positively affects employee’ labour productivity and the effectiveness of the entity, and the second teleworking complicates the management activities and affects negatively the socio-emotional environment in the work team. The objectives of the study are to identify whether the process of telework affects positively or negatively the organization’s current labour processes and propose multiple recommendations regarding to improve the telework mechanism for enabling prospective labour concerns in the human resources field of Uzbekistan. To achieve the objectives, a survey research design was adopted. The techniques employed in analyzing the data were quantitative methodology, descriptive statistics and Pearson's correlation coefficient. The results indicated that working from the home policy has a strong and positive relationship with employee’ labour productivity and the effectiveness of the entity if it is measured as a result-oriented rather than activity. It was also found that teleworking has a significant relationship with complicatedness of the management and it brings to the negative socio-emotional environment in the work team. Based on the findings, the researcher concluded that unexpected telecommuting in the period of Covid-19 has both negative and positive impact on employee performance and the entity`s management control.
