BACKGROUND

COVID-19 has continued to spread in the United States and globally. Closely monitoring public engagement and perceptions of COVID-19 and preventive measures using social media data could provide important information for understanding the progress of current interventions and planning future programs.

OBJECTIVE

The aim of this study is to measure the public’s behaviors and perceptions regarding COVID-19 and its effects on daily life during 5 months of the pandemic.

METHODS

Natural language processing (NLP) algorithms were used to identify COVID-19–related and unrelated topics in over 300 million online data sources from June 15 to November 15, 2020. Posts in the sample were geotagged by NetBase, a third-party data provider, and sensitivity and positive predictive value were both calculated to validate the classification of posts. Each post may have included discussion of multiple topics. The prevalence of discussion regarding these topics was measured over this time period and compared to daily case rates in the United States.

RESULTS

The final sample size included 9,065,733 posts, 70% of which were sourced from the United States. In October and November, discussion including mentions of COVID-19 and related health behaviors did not increase as it had from June to September, despite an increase in COVID-19 daily cases in the United States beginning in October. Additionally, discussion was more focused on daily life topics (n=6,210,255, 69%), compared with COVID-19 in general (n=3,390,139, 37%) and COVID-19 public health measures (n=1,836,200, 20%).

CONCLUSIONS

There was a decline in COVID-19–related social media discussion sourced mainly from the United States, even as COVID-19 cases in the United States increased to the highest rate since the beginning of the pandemic. Targeted public health messaging may be needed to ensure engagement in public health prevention measures as global vaccination efforts continue.

Published: December 2020

Large forces and significant thermal effects are created on the rolls when rolling sheets. The higher the stability of the rolls, the less downtime during their rerolling and higher productivity. (Research purpose) The research purpose is in analyzing the ways of restoring rolls and choose the most appropriate method for restoring these parts. (Materials and methods) The article presents the analysis of the scientific and technical literature on the topic of rolling production, methods for restoring large-sized machine parts of machine-building and metallurgical industries that work in difficult conditions and are subject to a high degree of wear. Authors try to solve the problem by means of comparative and logical analysis based on theoretical and empirical methods of scientific research. (Results and discussion) The article presents two groups of methods for restoring rolled rolls: banding and surfacing the working layer of the roll. Authors have analyzed each method in terms of technology, equipment, and feasibility. The article presents the advantages and disadvantages of the methods under consideration. (Conclusions) The most acceptable way to restore parts with a high degree of wear is surfacing. It is most efficient to apply submerged surfacing using an additional hot additive. Such surfacing, despite some complication of the equipment design, allows to deposit the metal on the roll with low heat input and in most cases in one pass. Surfacing using an additional hot additive allows to increase the productivity of the process by up to 250 percent while reducing the penetration depth by 2-3 times and saving energy by up to 40 percent.

Published: December 2020

During operation, there are occur failures of the Sauer-Danfoss 90 series hydraulic drive, resulting in downtime of equipment and losses to operating companies. It is not always possible to determine the true cause of the loss of performance of an imported hydraulic drive due to its low level of knowledge and complexity of the design. (Research purpose) The research purpose is in studying the influence of pressure in the control system on the performance and durability parameters of the Sauer Danfoss 90 series volumetric hydraulic drive. (Materials and methods) An analysis of the design and works devoted to the study of the failures of volumetric hydraulic drives allows proposing a new scheme for loss of performance and outlining ways to improve the durability of the Sauer Danfoss 90 series. (Results and discussion) The pressure values in the control system were calculated for the pumping unit of the 90R100, at which the pumping unit moves from the minimum to the maximum position, which was confirmed experimentally using bench equipment. The difference between the calculated and experimental values is 0.04-0.07 megapascals. The increase in productivity in the control system leads to an increase in the performance parameters and to an increase in the pre-repair life of the Sauer Danfoss 90 series hydraulic drive. (Conclusions) To improve pre-repair life of a Sauer Danfoss hydraulic drive it is required the use of more powerful feed pump, as at the same values of the clearances in the joints, he is able to compensate for leakage of working fluid longer, while maintaining the performance above the limits.

Published: December 2020

The most complex operation in the technological process of bread production is the division of the finished dough into blanks of the same mass. Vacuum-piston type dough separators perform this operation. Under operating conditions, the service life of the machines is 30-40 percent lower than the manufacturer's stated one. (Research purpose) The research purpose is in studying the permissible values of wear on the working surfaces of parts of vacuum-piston type dough dividing machines without repair. (Materials and methods) The article considers the method of multiple regression, which consists in studying the relationship between the maximum wear of the working surfaces of parts and the consumption of edible oil to determine the permissible sizes of parts of dough-dividing machines without repair. The parts were measured in several cross-sections in width and height. The sections were selected at the points of contact of the parts when they were moved relative to each other during the working stroke. (Results and discussion) The article presents a statistical relationship between the consumption of edible oil and the significantly affecting wear of the working surfaces of the parts of the dividing device of dough dividing machines. The values of permissible wear on the working surfaces of parts were determined by the method of steep ascent. (Conclusions) Using the method of multiple regression, the received linear regression equation adequately describes the relationship of the consumption of edible oil with the wear surfaces of separating device of TD-4 vacuum-piston type dough dividing machines. Authors determined the wear on the surfaces of parts of dividing devices and their influence on the dependent variable, the consumption of edible oil. The obtained values are fundamental for fault detection and the choice of a method for restoring worn surfaces of parts.

Raksts sniedz ieskatu 1795. gadā Varšavā publicētā Mihala Jana Borha dzejojuma Jardin sentimental du château de Warkland literārajos un kultūrvēsturiskajos kontekstos. Borha sacerējums nāk klajā gandrīz vienlaikus ar ievērojamāko libertīnu romānu marķīza de Sada „Justīne jeb tikumības nedienas“ (1791).

Purpose. The aim of the paper is to study the polar low on January 18–20, 2017 using the sensitivity numerical experiments. The experiments were performed to analyse direct effect of the surface energy fluxes and condensational heating on the cyclone structure and intensity. Methods and Results. The Polar WRF model was used for the cyclone simulations. In order to study the cyclone direct response to the changes in the model, all the experiments started only after the polar low had reached its mature stage at 00:00 on January, 20. Five numerical experiments were performed, in which the following parameters were turned off: 1) sensible heat flux only, 2) latent heat flux only, 3) both surface energy fluxes, 4) phase change heat transfer in the atmosphere and 5) phase change heat transfer in the atmosphere as well as surface energy fluxes. The cyclone intensity was defined by the minimum sea level pressure in its center. Conclusions. It is shown that in all the numerical experiments, the cyclone intensity as well as its maximum wind speed at the model lowest level decreased. In experiments 1 and 2, the intensity decrease was nearly the same, i.e. at the mature stage, the sensible and latent heat fluxes were equally important for the cyclone intensity. In experiments 1, 3 and 5 (with the sensible heat flux turned off), the atmosphere static stability increased significantly due to considerable decrease of the air temperature at the model lowest level. In experiment 4, the planetary boundary layer became more unstable since evaporative cooling was turned off in the model. In experiments 1, 3 and 5, integral kinetic energy of the cyclone increased despite the fact that its intensity and maximum surface wind speed decreased. It is shown that such a response of the cyclone was, most probably, caused by decrease of the energy dissipation in the surface layer due to the increased atmospheric stability.
At the origins of “dachа topos”:marginalia of an unfinished work by Yu.M. Lotman
Authors:   University of Viterbo, Emilio Mari
Published: December 2020

In the autumn of 1991, two years before his death, at the invitation of the Pushkinsky Fond, Lotman began working on a 3-volume history of the Russian nobility through the everyday life of the Durnovo family from St. Petersburg. The second volume was published posthumously in 1996, but all that remains of the third is the introductory fragment entitled «Kamen’ i trava». Despite its brevity and incompleteness, this essay nevertheless deserves attention, because it leads us to reflect on a fundamental rupture in pre-revolutionary cultural history, namely the disintegration of the dual structure of Russian society (aristocracy–peasants) and the rise of a “third” class between them: the urban middle class. Lotman, like Chekhov before him, traces this passage focusing on changes in the noble country estate: its slow degradation and its progressive “democratization” and transformation into dacha. Drawing on heterogeneous sources, from high poetry to mass literature, the scholar offers reflections of astonishing insight and perception that, if reread in the light of the cultural and anthropological debate developed in the 25 years since the author’s death, help to understand the roots of contemporary practices and phenomena such as mass tourism, changes in taste and the affirmation of kitsch, the weakening of cultural and epistemological categories that were once “strong” like the Self and the Other, the Here and the Elsewhere.
“Bequeathed life of the apple trees”in the age of social catastrophe: the estate garden in prose by L.F. Zurov
Authors:   State University of Pskov, Razumovskaya Aida G.
Published: December 2020

The article traces the image of the estate, mainly, of the estate garden throughout the entire work of L.F. Zurov: in the story “Cadet”, the novels “The Ancient Way” and “The Field”, stories from the storybook “Maryanka”. The author’s attention is focused on the crucial era of revolutions and wars, against the background of which the ambiguity of the functions of the estate garden is revealed. Despite the specificity of the descriptions, it always appears in an existential projection. On the one hand, the garden is subjected to violent destruction, and on the other, it sets off the state of mind of the heroes, proving the inextricable link of a tree and a man. The author explains the selection of trees that inhabit the garden (apple tree, linden, fir tree, alder, etc.). But the main thing is that the image of the estate garden has an ontological coloring: it combines the transitory and the eternal, the semantics of eternal life and beauty are preserved, there is hope for the revival of the lost paradise.
Byzantine ideas about the heavenly Kingdomand semiotics of the estate in modern Greekand Russian literature of the XVIII–XX centuries
Authors:   Institute of World History of the Russian Academy of Sciences, Shchegoleva Lyudmila I.
Published: December 2020

The article analyzes works of Byzantine, New Greek and Russian literature of the late XVIIIth — first half of the XXth century, belonging to the common cultural space of the Eastern Christian world: “The Life of St. Basil the Younger”, “Philotheou parerga” by Nikolaos Maurokordatos, “Pure Liza” by N.M. Karamzin, “Eugene Onegin” by Alexander Pushkin, “The Cherry Orchard” by Anton Chekhov, “The Master and Margarita” by Mikhail Bulgakov. It is revealed that in all works the story space is divided into two archetypal loci: “city” (Constantinople / Moscow / Petersburg / Paris) and “garden” (paradise garden / town estate / country estate). It is shown that the locus of “city” correlates with such concepts as “evil”, “lawlessness”, “danger”, “nonfreedom”, “aggression / mutilation / murder”, “sin”, “deception / betrayal / treachery”, and locus “garden” — with concepts of “good”, “legitimacy”, “security”, “freedom”, “love / friendship / benevolence”, “virtue”. It is proved that in each of the works it is possible to distinguish a common set of extremely generalized immutable features, going back to a single archetypal source. It is concluded that a certain number of key characteristics of the Russian estate of the XVIII — early XX century as regards their origin can be correlated with Greek-Byzantine sources.
The time of Art Nouveauin the literary and artistic comprehensionof Maurice Maeterlink in the context of Hanbury Gardens, Liguria
Authors:   Dmitry Likhachev Russian Research Institute of Cultural and Natural Heritage, Grafova Elena O.
Published: December 2020

The garden is the most important element of the “estate topos”. The idea of Ligurian gardens, created by philanthropists Daniel and Thomas Hanbury and embodied by landscape designer, botanist and garden architect Louis Winter, is to collect plants from around the world and give them a new “read” in the gardens of a “beautiful era”.This idea of travel, of attention to plants, flowers whose seeds can be collected in different parts of the world (in Japan, China, Australia, on the African continent, in the Americas), carries the idea of beauty, variety in simple and complex. The image of a flower as a unique creature, whose life is full of great meaning – moving towards sunlight, overcoming the obstacles that stand in its way — is one of the most important symbols of the modern era. The beauty of a flower that reaches out to the light is a key idea in the art edition “The Mind of Flowers” (1907) by Maurice Meterlink.

Published: December 2020

O objetivo deste trabalho é calcular a descarga líquida (Qliq) e descarga sólida (Qss) no Rio Guaíba utilizando um sensor perfilador acústico de correntes por Doppler (PACD) comparar a Qliq medidas com a vazão dos rios tributários, oscilações de nível da água, direção e intensidade dos ventos. Foi criada uma equação de calibração do PACD para estimar a concentração de sedimentos em suspensão (CSS) e Qss comparando dados do método gravimétrico in situ e de retroespalhamento acústico do PACD. Uma relação exponencial se adaptou melhor no conjunto de dados, com R² de 0,7. Foi possível realizar um estudo abrangente sobre as variáveis Qliq e Qss no Guaíba. Os dados de Qliq medidos possuem valores próximos à soma dos dados de vazão dos rios Jacuí, Taquarí, Caí e Sinos. Não foi possível ajustar uma curva-chave entre vazão e a régua localizada no Cais Mauá devido as oscilações do vento que alteram o nível da água na desembocadura deste sistema fluvial, inclusive com situações de inversão do fluxo registradas nos perfis de corrente que foram relacionadas com a ocorrência de ventos nos quadrantes S e SE. Para a variável Qss, os valores apresentaram grande variabilidade, com mínimos e máximos de 776 a 118.130 t/dia. A possibilidade da calibração do sensor PACD para estimar o CSS no Guaíba serve como base para estimar a quantidade de volume de sedimentos que ingressam no Guaíba.
(no)boundaries: A Study in Free Improvisation
Authors: Andrew Bain
Published: December 2020

This practice-led research project investigates the importance of an empathically creative connection between freely improvising musicians in a live context with no pre-conceived ideas and details the development of instantaneous group composition. As such, (no)boundaries had no pre-composed music, there was no rehearsal period for the musicians (myself playing drums), and we had never played together before the first note of performance. In my research to date, the dynamic between pre-learned knowledge (embodied) alongside intelligent transactions during live improvisation (enacted knowledge), has been useful in helping to better understand the process of jazz improvisation. Even if there are pre-conceived elements, how the music is realised each time is unique. Conversely, even if we set out to have no pre-conceived ideas, in reality, we are still intuitively informed by our experiential and musical knowledge in performance. The two seem inextricably linked.
(no)boundaries showed that group attunement in performance is possible with no pre-learnt repertoire or rehearsals, in an appropriate setting with the right co-performers. Even though no pre-conceived ideas were intended, (no)boundaries evidenced improvisations guided by similar principles of standard jazz performance, pointing to the existence of a common performance mode.

Authors: Montoya Francisco , Baños Raul , Alcayde Alfredo , Arrabal-Campos Francisco M. , Roldan-Perez Javier
Published: December 2020

This paper presents a new framework based on geometric algebra (GA) for
solving and analysing three-phase balanced electrical circuits under
sinusoidal and non-sinusoidal conditions. The proposed approach is an
application of the geometric algebra power theory (GAPoT) to three-phase
systems. Calculations are performed in a multi-dimensional Euclidean
space where cross effects between voltage and current harmonics are
taken into consideration. A definition of geometric apparent power for
three-phase systems that complies with the energy conservation theorem
is introduced. By using the proposed framework, the current can be
easily decomposed into active- and non-active components for current
compensation purposes. The paper includes detailed examples in which
electrical circuits are solved and the results are analysed. This work
is a first step towards a more advanced polyphase proposal with
realistic cases, where unbalance and asymmetry is included.

Better once it's over, worse now: Prospective moral behaviors after the coronavirus epidemic and cyberchondria
Authors: Maftei Alexandra , Holman Andrei
Published: December 2020

The COVID?19 crisis might generate effects in what regards people?s propensity to engage in moral and immoral actions, both during and after the pandemic. We used an experimental manipulation to explore the impact of the current lockdown on anticipated behaviors and its association with cyberchondria and moral identity. A convenience sample of 865 participants completed an online survey in which they were asked to rate the probability of engaging in certain morally positive and negative behaviors over the next week. The experimental group was required to imagine that the pandemic would be over by then, and all restrictions would be lifted, while the control groups did not receive this instruction. Participants? moral identity and cyberchondria were also measured. Results showed that participants in the experimental condition expressed higher intentions to perform positive behaviors and lower intentions to engage in negative actions. Furthermore, cyberchondria was positively associated both to intended negative behaviors in the control group, i.e., during the lockdown and to positive behaviors in the experimental group, i.e., after the lockdown. We discuss these results in relation to prospective moral licensing and cleansing, and to the role of health anxiety in shaping moral decisions.
Global Well-Being Is Associated With A1C and Frequency of Self-Monitoring of Blood Glucose in Predominately Latinx Youth and Young Adults With Type 1 Diabetes
Authors: Addala Ananta , Chan Randall Y. , Vargas Jaclyn , Weigensberg Marc J.
Published: December 2020

The 2020 American Diabetes Association’s Standards of Care underscore the importance of psychosocial screening in all persons with type 1 diabetes as an important step in optimized type 1 diabetes management. Youth with type 1 diabetes from low socioeconomic backgrounds and from minority racial groups have increased psychosocial burden but often do not meet psychosocial screening guidelines. We present findings from psychosocial measures in a predominately Latino and low socioeconomic cohort. Our findings demonstrate:

(1) higher global health scores were strongly associated with both lower HbA1c and more frequent self-monitoring blood glucose
(2) given that the study population was predominately young adults, these are important considerations in the transition of care
(3) successful psychosocial screening in a resource limited urban hospital
(4) associations between HbA1c and SMBG and psychosocial measures support increasing attention to assessing and optimizing positive psychological states as a means to improve diabetes outcomes

Our motivation for this study is to demonstrate that psychosocial screening is both clinically meaningful and feasible, particularly in this age of transition. Therefore, diabetes clinics should strive to meet national and international guidelines by screening all persons with type 1 diabetes for psychosocial stressors as a means of improved type 1 diabetes care.

Consistent with the aim of Diabetes Spectrum, this manuscript aims to reach health care providers to promote better management of persons with type 1 diabetes, including those from the most vulnerable subgroups. We look forward to hearing from your editorial office regarding this manuscript. Thank you for your consideration.

Published: December 2020

Pure copper rods were additively fabricated by using a multibeam type laser metal deposition (LMD) device equipped with two blue diode lasers, and the influence of them on the rods was investigated. It is unknown how the rod changes with respect to the process parameters such as the laser power and the powder feeding rate. In this study, the laser power and the powder feeding rate were changed to form a pure copper rod in the LMD method, and the influence of them on the cross-sectional area of the rod was investigated. Moreover, the electrical resistance value of the rod was measured, and the influence of the laser power on the electrical resistivity was investigated. In addition, the elemental analysis of the cross section was performed by an electron probe microanalyzer, and the influence of the laser power was investigated. As a result, the cross-sectional area of the rod is slightly dependent on the powder feeding rate, and even if the powder feeding rate is increased, the cross-sectional area is slightly increased, but when the laser power is increased, the cross-sectional area is significantly increased. Moreover, when the laser power was increased, the electrical resistivity increased. The elemental analysis revealed that the surface of the rod might be oxidized, which suggested that it affected the electrical resistivity.
Studies of Changes in the Electrical Resistivity of Rocks of the Tashtagol Mine in a Critical Rock-bump Hazardous State Based on the Kinetic Concept of Solids Destruction
Authors:   AO «NTs VostNII», Lee K.Kh. , Ivanov V.V. ,   AO «NTs VostNII»
Published: December 2020

Main hypotheses of the occurrence of seismic events centers, including rock bumps are presented. Equations of kinetic theory of strength are given. A two-stage kinetic model of crack accumulation and catastrophic destruction of rocks is formulated. It consists in the fact that at the first stage of the rock bump preparation there is a diffuse accumulation of cracks, and at the second — merging of cracks, appearance of enlarged cracks and formation of the destruction center. The results are presented concerning the theoretical and laboratory measurements of change of specific electric resistance of the host rocks and ores of iron ore deposit at mechanical loading and destruction. It has been shown that the relative change of specific electrical resistance of the low conductive rocks depends significantly on the ratio of electrical resistance of the rock itself and charged zones near the surface of the incipient cracks during rock loading. With the accumulation of cracks in the process of mechanical loading of the host rocks of the Tashtagol mine, the number of charged point defects of the structure on the crack edges increases. Specific electrical resistance of such rocks decreases with the accumulation of the number of cracks. In the ore bodies and magnetic iron ores, on the contrary, with increasing disturbance, the electrical resistance increases. There is regular change in the electrical resistance of rocks in the intermediate and limit states. For ores and magnetic iron ores, the critical change is 40 %, and for the host rocks with high electrical resistance — 28–37 %. Obtained values of change of the specific electric resistance in the rock critical state can be used for prediction of the rock bumps.
Risk Regulation and Management Related to the Operation of Hazardous Production Facilities
Authors:   IMASH RAN, Makhutov N.A. , Reznikov D.O. ,   IMASH RAN, Lisanov M.V. ,   STC «Industrial Safety» CJSC
Published: December 2020

The paper examines the types of uncertainties associated with operation of hazardous production facilities caused by the natural variability of the facility parameters and the limited knowledge about complex processes in the system under consideration, as well as the uncertainty of the results of quantitative risk assessment. Qualitative and quantitative criteria of tolerable (acceptable) risk adopted in various countries of the world are presented. The article considers the operation of the ALARP principle in making managerial decisions on the need to implement protective measures aimed at reducing individual risk, which allows to provide a compromise between competing requirements for ensuring safety and economic efficiency in the operation of hazardous production facilities. In the future of socio-economic development, due to the improvement of existing and the emergence of new safety technologies, the maximum allowable and acceptable levels of risk should be revised in order to meet more stringent safety requirements. Therefore, the value of tolerable individual risk in case of accidents at hazardous production facilities may not be a strictly specified value (as is generally accepted), but may decrease as the reliability of technological systems increases, the efficiency of industrial safety management increases, and the background (average) risk of mortality decreases. A necessary condition for implementing a risk management system is to improve the efficiency of the system for collecting and analyzing data on reliability, accident rate, monitoring and control of technical condition at hazardous production facilities, and further develop the methodological support for risk analysis within the framework of the currently implemented risk-oriented approach in the field of industrial safety.

Published: December 2020

The growth hormone receptor (GHR) gene encodes the type I cytokine receptor that helps in joining the growth hormone to this receptor, thus promoting receptor-dimerization, leading to up-regulating growth. The ovine GHR gene located on chromosome 16, which consists of 10 exons and 9 introns, along with untranslated regions on either side, comprise a total size of 178.09 kb. However, earlier reports about polymorphism have mainly dealt with exon 10 which is also a larger fragment of this gene comprising 1102 bp. Hence, this study was carried out to detect polymorphism in exon 10 of the GHR gene and its association with growth traits. Genomic DNA was isolated from blood samples of Madras Red and Mecheri sheep breeds from India. Part of exon 10 (895 bp) of the GHR gene was amplified and sent for sequencing. The sequence analysis revealed transition of nucleotide G>A at loci G177624A and G177878A in both sheep breeds. Populations were screened by Tetra-primer ARMS-PCR. The genotype frequencies of GG, GA and AA were 0.276, 0.519 and 0.205 at 177624 G>A, and 0.307, 0.444 and 0.149 at 177878 G>A in Madras Red sheep; whereas in Mecheri they were 0.476, 0.372 and 0.152 at 177624 G>A, and 0.629, 0.314 and 0.057 at 177878 G>A, respectively. Likewise the estimated allele frequencies of G and A were 0.5355 and 0.4645 at 177624 G>A, and 0.5790 and 0.4210 at 177878 G>A in Madras Red sheep; whereas in Mecheri they were 0.6620 and 0.3380 at 177624 G>A, and 0.7860 and 0.2140 at 177878 G>A, respectively. The effect of sex was significant for birth, six and nine month weight; but non-significant for three and 12 month weight in Mecheri sheep. However, in the Madras Red breed the effect of sex was significant for all body weights except weaning weight. The effect of variations on growth traits, viz., birth weight, weight at weaning, and weight at six, nine and twelve months in both breeds were analysed for their association, and they were found non-significant. Since these SNPs are salient findings of GHR gene polymorphism in Indian sheep breeds, further investigation is required into the significant effects of these novel SNPs, which could be useful for genetic improvement based on marker assisted selection.

Stallions are natural reservoirs of equine arteritis virus (EAV) in their semen, representing a potential source of outbreaks. The carrier-state is testosterone-dependent, and clears spontaneously in 4 to 40% stallions. Reduction of testosterone secretion may be obtained with the anti-GnRH vaccine Equity. In this report, 16 naturally infected stallions excreting EAV in their semen were vaccinated twice with the vaccine EquityTM and monitored irregularly under field conditions for EAV viral load in their semen and plasmatic testosterone concentration. The results are indicated in months (M) after the first vaccine injection. Testosterone concentrations decreased from 1.7 to 0.2 ng/mL (P<0.002) after 3M. The EAV viral load decreased from 3.2×109 to 1.1×106 RNA copy/mL of semen (P<0.001) after 5M. One stallion died at 7M for other reason. At M3-10, 12/15 stallions ceased to shed the virus in their semen. At M5-10, 9/15 stallions had plasmatic testosterone concentrations of ≥ 0.5 ng/mL but the 6 others showed a persistently low testosterone concentration (≤0.3 ng/mL). Of the 14 stallions that were expected to recover their reproductive activity at the time of the next breeding season (<M12), 8 were EAV negative and produced foals, and 6 were not usable (4 for reproductive deficiency and 2 for EAV positivity). All the stallions were EAV negative at M22, with one stallion being vaccinated a third time at M15. These results suggest that the anti-GnRH vaccination could help to clear EAV shedding in stallions, without a significant effect on reproductive capacity for most of them, but some present a long lasting reduced testosterone secretion.
The Emerging Research Field of Sustainability Transitions
Authors: Silva Neto Victo
Published: December 2020

This article try to understand the process of formation of the sustainability transitions (ST) research field. The hypothesis of this article states that the field arises through a process of speciation: gradual differentiation, from an older and already established research field (innovation studies). This exercise is useful both as a first approximation into the history of ST thought and as a means to assess the explanatory potential of different approaches towards scientific advance (epistemological discussion). Our proxy to investigate the evolution of the field is the ST language or scientific lexicus and how it came to be. The methodology to assess the evolution of this object is threefold: documental analysis; critical review of the literature (retrofitted concepts and proto-ideas) and bibliometric analysis. The documental analysis provides evidence that ST is an emergent scientific field. A critical review of the literature points to connections and redetermination of pre-existent concepts and terms from the innovation studies area; bibliometric evidence points to a movement of distancing: after building its own lexicon coherent to its problem framing, ST research area is gradually leaving innovation studies terms and concepts behind. General results point to a process of speciation, reinforcing the explanatory potential of epistemological evolutionism.
Wiedza w procesie zarządzania zakładem ubezpieczeń w kontekście budowania wartości konsumenckiej oraz planów emerytalnych usługi ubezpieczeniowej
Authors: Grzebieniak Andrzej
Published: December 2020

Celem naukowo-badawczym monografii jest przybliżenie odbiorcom m.in. znaczenia wiedzy ubezpieczeniowej w procesie zarządzania zakładem ubezpieczeń, problematyki zachowań konsumentów na rynku usług ubezpieczeniowych, oraz określenie, w jakim stopniu usługi ubezpieczeniowe mogą oferować rozwiązania w zakresie dodatkowych planów emerytalnych realizowanych w ramach w trzeciego filaru emerytalnego. Monografia została podzielona na trzy rozdziały. W rozdziale pierwszym scharakteryzowano niezbędną wiedzę, jaką musi posiadać zakład ubezpieczeń, aby sprostać wymaganiom konsumentów usługi ubezpieczeniowej nie tylko w zakresie wartości w postaci zabezpieczenia finansowego na okoliczność zrealizowania się ryzyka ubezpieczeniowego, ale także zaspokojenia ich coraz bardziej zindywidualizowanych oczekiwań i potrzeb, jakości niezależnie od poziomu cenowego produktu, czy też profesjonalnej obsługi. W rozdziale drugim przedstawiono potrzeby konsumentów usług ubezpieczeniowych, które koncentrują się przede wszystkim na otrzymaniu usługi wysokiej jakości i spełniającej w pełni ich potrzeby. Oczekiwania te zostaną spełnione, jeśli oferowane usługi ubezpieczeniowe będą wypełniać podstawowe zasady ochrony ubezpieczeniowej, czyli zasadę powszechności, zasadę pełności oraz zasadę realności. W im większym stopniu zasady te zostaną spełnione przez zakłady ubezpieczeń, tym wyższa będzie jakość oferowanych przez nich usług ubezpieczeniowych. W rozdziale trzecim opisano oferowane przez zakłady ubezpieczeń produkty ubezpieczeniowe, które akumulują i pomnażają oszczędności, czyli produkty, które mogą być wykorzystane w budowaniu dodatkowych planów emerytalnych. Takie emerytalne aspekty wykazują opisane w monografii wybrane produkty ubezpieczeń na życie.

The aim of this paper is to present the results of geophysical surveys at the Staré zámky site near Brno-Líšeň, which were carried out in 2019. Electrical resistivity tomography, georadar survey and large-scale magnetic prospection were all carried out there. The primary task of the first two methods was to investigate the inner structure of the still-existing ramparts and to identify their individual structural elements. The magnetic survey focused on the identification of areas where potential archaeological features can be found – together with the identification of previously-unknown fortifications. The surveys were successful: we have found numerous settlement features from different phases of settlement, an early medieval cemetery and fortifications of various types, sizes and state of preservation. The results of previous archaeological research of the site played an important role for interpretation of the geophysical data. Together these results provide important insights into the study of the complex fortified settlement of Staré zámky. Despite our results, some questions which cannot be answered by geophysical research alone remain unanswered.

Published: December 2020

Bahasa adalah alat komunikasi yang digunakan manusia untuk saling berinteraksi. Bahasa dapat secara sengaja maupun tidak disengaja diubah menjadi sebuah permainan kata. Salah satu permainan kata dalam bahasa Jepang adalah dajare. Dajare dikenal sebagai banyolan yang hambar. Dalam kehidupan sehari-hari orang Jepang, jarang ditemukan percakapan dengan menggunakan dajare. Hal ini dikarenakan dajare dianggap sebagai lelucon orang tua. Namun, dalam animasi Shirokuma Cafe terdapat dajare hampir di setiap episode. Penelitian ini bertujuan untuk mendeskripsikan dajare dalam animasi Shirokuma Café karya Higa Aloha, khususnya Near-homophonic dajare. Penelitian ini menggunakan klasifikasi dajare yang dikemukakan oleh Takashi Otake. Metode penelitian yang digunakan adalah metode deskriptif kualitatif. Data yang ditemukan adalah 10 cuplikan percakapan yang di dalamnya terdapat 34 dajare. Setelah dianalisis diketahui dari 34 dajare, 30 dajare termasuk ke dalam Near-homophonic dajare yang pembentukannya dilakukan dengan mengubah segmen, yaitu mengubah vokal (V-Change), konsonan (C-Change), dan mora (M-Change).
