Abstract. Prihatiningsih N, Asnani A, Djatmiko HA. 2021. Extracellular protease from Bacillus subtilis B315 with antagonistic activity against bacterial wilt pathogen (Ralstonia solanacearum) of chili.  Biodiversitas 22: 1291-1295. Antagonistic bacteria isolated from a healthy potato are potential biocontrol agents against a number of bacterial pathogens. The capability of antagonistic bacteria to produce extracellular protease could be considered as an indicator of their antagonistic capacity. The objective of this research was to study the optimum activity of protease produced by Bacillus subtilis B315 to control Ralstonia solanacearum causing wilt of chili. In this research were optimum incubation time, pH and crude extract protease concentration of B. subtilis B315 examined for maximum production of extracellular protease. The results showed that B. subtilis B315 was capable of producing protease at optimum incubation time of 30 min, pH 9, and crude extract protease concentration 0.50% with an activity of 1.3185 U/mL. Protease-producing capability of B. subtilis B315 was shown by the formation of a clear zone around the colony of B. subtilis B315 grown on skim-milk agar medium. B. subtilis B315 was capable of inhibiting the growth of R. solanacearum in vitro as indicated by 32 mm clear zone. Furthermore, in chili application of B subtilis showed that this bacteria was capable of controlling chili bacterial wilt caused by R. solanacearum with effectiveness of 60.89%. The prospective of B. subtilis B315 could be formulated as biopesticide.
Nonparaxial scalar diffraction theory modifications for improved efficiency estimation
Authors: Madsen C. K.
Published: February 2021

Using the nonparaxial scalar diffraction equations to estimate the diffraction efficiency of multiple orders of a sinusoidal reflection grating, we compare the results of transverse electric (TE) and transverse magnetic (TM) vector wave simulations for a reflective surface on glass. Modifications are presented that enable the nonparaxial scalar solution to approximate simulation results in each order to within 1% to 2% across a 0 to 90 deg range of incidence angles when the diffracted power is predominantly carried in the first several orders, up to the fourth order. The accuracy of simulations in this regime is particularly important for surface scattering where individual spatial frequencies typically have amplitudes much less than a hundred nanometers. A substantial reduction in the error between vector simulations and scalar estimation of diffraction efficiency is demonstrated with the following modifications: (1) an obliquity factor correction for the specular order based on a first-order power conservation criterion, (2) a “cutoff” factor modifying the obliquity factor as the diffracted angle approaches 90 deg for each order, and (3) nonuniform unallocated power distribution near the low-order cutoffs. The second and third modifications are applied to higher diffraction orders for extending the range of applicable grating heights up to 200 nm (peak-to-valley), periods down to twice the wavelength, and slopes up to 0.2 (root mean square).

Managing the pandemic caused by SARS-CoV-2 requires new capabilities in testing, including the possibility of identifying, in minutes, infected individuals as they enter spaces where they must congregate in a functioning society, including workspaces, schools, points of entry, and commercial business establishments. Here, the only useful tests (a) require no sample transport, (b) require minimal sample manipulation, (c) can be performed by unlicensed individuals, (d) return results on the spot in much less than one hour, and (e) cost no more than a few dollars. The sensitivity need not be as high as normally required by the FDA for screening asymptomatic carriers (as few as 10 virions per sample), as these viral loads are almost certainly not high enough for an individual to present a risk for forward infection. This allows tests specifically useful for this pandemic to trade-off unneeded sensitivity for necessary speed, simplicity, and frugality. In some studies, it was shown that viral load that creates forward-infection risk may exceed 105 virions per milliliter, easily within the sensitivity of an RNA amplification architecture, but unattainable by antibody-based architectures that simply target viral antigens. Here, we describe such a test based on a displaceable probe loop amplification architecture.
A casino in my pocket: Gratifications associated with obsessive and harmonious passion for mobile gambling
Authors: Whelan Eoin , Laato Samuli , Islam A. K. M. Najmul , Billieux Joël
Published: February 2021

Mobile gambling differs from land-based and traditional forms of gambling in that the opportunity to place bets and engage with casinos is constantly present and easily accessible. Instead of going to a physical bookmaker or casino, mobile gambling is done quickly and swiftly, anytime, anywhere, with a few taps on a mobile device. Previous studies reveal mobile gambling has managed to reach new audiences especially amongst younger people. Gambling harms can have severe adverse effects on individuals, families and society. However, for a subgroup of highly involved individuals, gambling can be considered a harmonious passion that permits frequent gambling without elevating individual’s risks of experience problem gambling manifestations. Combining the Uses and Gratifications (U&G) and Dualistic Model of Passion (DMP) frameworks, the present study aims to determine if and how the different gratifications sought from mobile gambling are susceptible to explaining non-problematic versus problematic patterns in highly involved gamblers. Data were collected over two waves from a global sample of mobile gamblers (N = 327). Results emphasize that the motivational underpinnings of mobile gambling (as measured by the U&G) differ in obsessive versus harmonious passion. Obsessive passion is associated with poor mood and problematic gambling. In contrast, harmonious passion for mobile gambling is associated with positive mood but is unrelated to problematic gambling. Based on these findings, and given that problematic gambling is an internationally relevant public health issue (the prevalence of problem gambling is estimated to range from 0.1% to 5.8% in different countries), we suggest interventions focusing on specific uses and gratifications associated with an obsessive passion for mobile gambling may be effective in reducing problematic usage patterns.
New perspectives on satisfaction and loyalty in festival tourism: The function of tangible and intangible attributes
Authors: Molina-Gómez Jesús , Mercadé-Melé Pere , Almeida-García Fernando , Ruiz-Berrón Raquel
Published: February 2021

This research explains how attributes perceived during the festival celebration generate loyalty in terms of satisfaction. As regard, tangible aspects (festival entertainment and aesthetics) and intangible aspects (escapism and education) shall be differentiated. A theoretical model is proposed, which explains the effects of festival attributes on satisfaction and loyalty through structural equation modelling. The model was estimated with a sample of 440 people attending Weekend Beach Festival in Spain. The research proves the relationship between attributes and loyalty through satisfaction as a moderating variable; likewise, tangible attributes are deemed to have a greater influence on loyalty, specifically, the aesthetic/environment experience.
First rebbachisaurid sauropod dinosaur from Asia
Authors: Averianov Alexander , Sues Hans-Dieter
Published: February 2021

Dzharatitanis kingi gen. et sp. nov. is based on an isolated anterior caudal vertebra (USNM 538127) from the Upper Cretaceous (Turonian) Bissekty Formation at Dzharakuduk, Uzbekistan. Phylogenetic analysis places the new taxon within the diplodocoid clade Rebbachisauridae. This is the first rebbachisaurid reported from Asia and one of the youngest rebbachisaurids in the known fossil record. The caudal is characterized by a slightly opisthocoelous centrum, ‘wing-like’ transverse processes with large but shallow PRCDF and POCDF, and the absence of a hyposphenal ridge and of TPRL and TPOL. The neural spine has high SPRL, SPDL, SPOL, and POSL and is pneumatized. The apex of neural spine is transversely expanded and bears triangular lateral processes. The new taxon shares with Demandasaurus and the Wessex rebbachisaurid a high SPDL on the lateral side of the neural spine, separated from SPRL and SPOL. This possibly suggests derivation of Dzharatitanis from European rebbachisaurids. This is the second sauropod group identified in the assemblage of non-avian dinosaurs from the Bissekty Formation, in addition to a previously identified indeterminate titanosaurian.
Measuring the global impact of destructive and illegal fishing on maritime piracy: A spatial analysis
Authors: Desai Raj M. , Shambaugh George E.
Published: February 2021

Maritime piracy constitutes a major threat to global shipping and international trade. We argue that fishers turn to piracy to smooth expected income losses and to deter illegal foreign fishing fleets. Previous investigations have generally focused on cross-national determinants of the incidence of piracy in territorial waters. These investigations neglect piracy in international waters and ignore its spatial dependence, whereby pirate attacks cluster in certain locations due to neighborhood and spillover effects. We conduct a geographically disaggregated analysis using geo-referenced data of piracy and its covariates between 2005 and 2014. We demonstrate that the incidence of piracy in a particular location is associated with higher catch volumes from high-bycatch and habitat-destroying fishing, even when controlling for conditions in proximate coastal areas. We find, additionally, that illegal, unreported, and unregulated fishing exerts an especially pronounced effect on piracy. These findings highlight the need for anti-piracy solutions beyond enforcement to include the policing of fishing practices that are illegal or are perceived by local fishers in vulnerable coastal areas to be harmful to small-scale fishing economies.
Chemical constituents and phytochemical properties of floral maize pollen
Authors: Bujang Japar Sidik , Zakaria Muta Harah , Ramaiya Shiamala Devi
Published: February 2021

Currently, bee-gathered pollen (bee pollen) is commonly used worldwide as a dietary supplement and is recognized for its curative properties. Floral pollen is also important but is less recognized due to a lack of investigation. This study aims to determine the morphological characteristics and nutritional and phytochemical properties of floral maize pollen. Fresh pollen grains harvested from a farm of maize plants are yellow in colour and spheroid in shape. They change to amber and indented prismatic solid shapes when dehydrated. The main composition of floral maize pollen is carbohydrates (44.30±3.73%), followed by moisture (23.38±5.73%), crude proteins (17.16±3.13%), crude fibres (9.56±0.92%), and ash (4.98±0.11%), while the lowest content is observed for crude fats (0.62±0.06%). The predominant mineral is potassium (768.50±11.40 mg 100 g-1), followed by sodium (695.10±9.70 mg 100 g-1), calcium (147.20±12.60 mg 100 g-1), and magnesium (97.30±2.9 mg 100 g-1). The microelements (with average values) consist of iron (49.50±3.30 mg 100 g-1) and zinc (30.00±3.70 mg 100 g-1). Excellent phytochemical properties add value to floral maize pollen. Maize pollen contains a high total phenolic content (TPC) and total flavonoid content (TFC) of 783.02 mg GAE 100 g-1 and 1706.83 mg QE 100 g-1, respectively, and possesses strong antioxidant activity of 10.54 mg mL-1. Maize floral pollen and derived products can serve as future food resources for human consumption and as a source of functional and bioactive compounds in nutraceutical and pharmaceutical industries.
Modeling driver behavior in the dilemma zone based on stochastic model predictive control
Authors: Li Wenjun , Tan Lidong , Lin Ciyun
Published: February 2021

Driver behavior is considered one of the most important factors in the genesis of dilemma zones and the safety of driver-vehicle-environment systems. An accurate driver behavior model can improve the traffic signal control efficiency and decrease traffic accidents in signalized intersections. This paper uses a mathematical modeling method to study driver behavior in a dilemma zone based on stochastic model predictive control (SMPC), along with considering the dynamic characteristics of human cognition and execution, aiming to provide a feasible solution for modeling driver behavior more accurately and potentially improving the understanding of driver-vehicle-environment systems in dilemma zones. This paper explores the modeling framework of driver behavior, including the perception module, decision-making module, and operation module. The perception module is proposed to stimulate the ability to perceive uncertainty and select attention in the dilemma zone. An SMPC-based driver control modeling method is proposed to stimulate decision-making behavior in the dilemma zone. The operation module is proposed to stimulate the execution ability of the driver. Finally, CarSim, the well-known vehicle dynamics analysis software package, is used to verify the proposed models of this paper. The simulation results show that the SMPC-based driver behavior model can effectively and accurately reflect the vehicle motion and dynamics under driving in the dilemma zone.
Clinical outcomes of proximal gastrectomy for gastric cancer: A comparison between the double-flap technique and jejunal interposition
Authors: Kumamoto Tsutomu , Sasako Mitsuru , Ishida Yoshinori , Kurahashi Yasunori , Shinohara Hisashi
Published: February 2021

Background

The optimal reconstruction method after proximal gastrectomy (PG) has been debatable. Recent reports have shown that the double-flap technique (DFT) provides good outcomes in terms of postoperative nutritional status and quality of life. However, no study has compared the clinical outcomes of the DFT with other reconstruction methods. Here, we evaluated and compared the clinical outcomes between the DFT and jejunal interposition (JI) after PG for gastric cancer.

Materials and methods

The medical records of 34 consecutive patients who had undergone PG for upper third gastric cancer between January 2011 and October 2016 were reviewed retrospectively. The main factors investigated were surgical outcomes, postoperative nutritional status, symptoms, and endoscopic findings 1 year after surgery.

Results

Thirty-four patients were enrolled (DFT, 14; JI, 20). The operation time was similar between the two techniques (228 and 246 minutes for DFT and JI, respectively, P = 0.377), as were the rates of anastomotic complications (7% and 0% for DFT and JI, respectively, P = 0.412). Body weight loss was significantly lower in the DFT group than in the JI group (-8.1% vs -16.1%, P = 0.001). Total protein and albumin levels were higher in the DFT group than in the JI group (0% vs -2.9%, P = 0.053, and -0.3% vs -6.1%, P = 0.077, respectively). One patient in the DFT group and no patients in the JI group experienced reflux esophagitis (≥ grade B) (P = 0.393). Anastomotic strictures were not observed as postoperative complications in either group.

Conclusions

Surgical outcomes revealed that the DFT was safe and feasible, similar to JI. In terms of controlling postoperative body weight loss, the DFT is a better reconstruction technique than JI after PG.
Harmine inhibits breast cancer cell migration and invasion by inducing the degradation of Twist1

Published: February 2021

Breast cancer is the leading cause of cancer-related deaths in the United States. The majority of deaths (90%) in breast cancer patients is caused by invasion and metastasis–two features related to the epithelial-to-mesenchymal transition (EMT). Twist1 is a key transcription factor that promotes the EMT, which leads to cell migration, invasion, cancer metastasis, and therapeutic resistance. Harmine is a beta-carboline alkaloid found in a variety of plants and was recently shown to be able to induce degradation of Twist Family BHLH Transcription Factor 1 (Twist1) in non-small cell lung cancer cells (NSCLC). In this study, we show that harmine can inhibit migration and invasion of both human and mouse breast cancer cells in a dose-dependent manner. Further study shows that this inhibition is most likely achieved by inducing a proteasome-dependent Twist1 degradation. At the concentrations tested, harmine did not affect the viability of cells significantly, suggesting that its inhibition of cancer cell migration and invasion is largely independent of its cytotoxicity, but due to its ability to affect regulators of EMT such as Twist1. This result may facilitate the development of strategies that target Twist1 to treat metastatic breast cancer, as Twist1 is expressed at a high level in metastatic breast cancer cells but not in normal cells.
Behavioural and antennal responses of Aedes aegypti (l.) (Diptera: Culicidae) gravid females to chemical cues from conspecific larvae

Published: February 2021

Mass trapping of gravid females represents one promising strategy for the development of sustainable tools against Aedes aegypti. However, this technique requires the development of effective odorant lures that can compete with natural breeding sites. The presence of conspecific larvae has been shown to stimulate oviposition. Hence, we evaluated the role of four major molecules previously identified from Ae. aegypti larvae (isovaleric, myristoleic, myristic [i.e. tetradecanoic], and pentadecanoic acids) on the oviposition of conspecific females, as well as their olfactory perception to evaluate their range of detection. Using flight cage assays, the preference of gravid females to oviposit in water that previously contained larvae (LHW) or containing the four larval compounds was evaluated. Then, compounds and doses inducing the highest stimulation were challenged for their efficacy against LHW. Only isovaleric acid elicited antennal response, suggesting that the other compounds may act as taste cues. Pentadecanoic acid induced significant oviposition stimulation, especially when dosed at 10 ppm. Myristoleic acid and isovaleric acid deterred oviposition at 10 and 100 ppm, while no effect on oviposition was observed with myristic acid irrespectively of the dose tested. When the four compounds were pooled to mimic larvae’s chemical signature, they favored oviposition at 1 ppm but negatively affected egg-laying at higher concentrations. When properly dosed, pentadecanoic acid and the blend of compounds may be promising lures for ovitraps as they could compete with LHW. Due to their low volatility, their effect should be further evaluated under field conditions, in addition with long-range attractants for developing effective tools against gravid females.

Published: February 2021

Improvement in sesame drought tolerance at seedling stage is important for yield stability. Genetic approaches combing with conventional breeding is the most effective way to develop drought-tolerant cultivars. In this study, three traits and their relative values, including seedling weight (SW), shoot length (SL) and root length (RL), were evaluated under control and osmotic conditions in a recombinant inbred line (RIL) population derived from cross of Zhushanbai and Jinhuangma. Significant variation and high broad sense heritability were observed for all traits except SW under stress condition in the population. With this population, a high-density linkage map with 1354 bin markers was constructed through whole genome re-sequencing (WGS) strategy. Quantitative trait loci (QTL) mapping was performed for all the traits. A total of 34 QTLs were detected on 10 chromosomes. Among them, 13 stable QTLs were revealed in two independent experiments, eight of them were associated with traits under water stress condition. One region on chromosome 12 related to RL under osmotic condition and relative RL had the highest LOD value and explained the largest phenotypic variation among all the QTLs detected under water stress condition. These findings will provide new genetic resources for molecular improvement of drought tolerance and candidate gene identification in sesame.
Refolding and characterization of two G protein-coupled receptors purified from E. coli inclusion bodies
Authors: Heim Bastian , Handrick René , Hartmann Marcus D. , Kiefer Hans
Published: February 2021

Aiming at streamlining GPCR production from E. coli inclusion bodies for structural analysis, we present a generic approach to assess and optimize refolding yield through thermostability analysis. Since commonly used hydrophobic dyes cannot be applied as probes for membrane protein unfolding, we adapted a technique based on reacting cysteins exposed upon thermal denaturation with fluorescent 7-Diethylamino-3-(4-maleimidophenyl)-4-methylcoumarin (CPM). Successful expression, purification and refolding is shown for two G protein-coupled receptors (GPCR), the sphingosine-1-phosphate receptor S1P1, and the orphan receptor GPR3. Refolded receptors were subjected to lipidic cubic phase crystallization screening.

Equity in Black theatre history classrooms
Authors: Sperrazza Tyler
Published: February 2021

This article reflects on the experiences of a white male faculty teaching Black theatre history at a predominantly white institution. It views the Black theatre history classroom as a potential haven for theatre students of colour, and highlights the critical role of a white faculty member in honouring and protecting that space. It argues for the importance of self-reflection and humility on the part of white faculty as we engage with topics surrounding Black history. This piece references the traditional power dynamics between students and faculty, and reimagines those power dynamics when white faculty members teach Black theatre history to Black students. In our current moment of racial upheaval and reckoning within the rehearsal rooms and on our stages, this reflection contends that we must also examine the ways in which our pedagogy in Black theatre history can be actively antiracist. Ultimately, this piece advocates that white faculty work to de-centre their own whiteness in their theatre history classrooms and commit to humility and a willingness to learn from their students of colour.
Monologic ethics: The single speaker as discursive partner in Anna Deavere Smith’s Twilight: Los Angeles, 1992
Authors: Tabor Nicole
Published: February 2021

This reflective article asserts that the monologue form helps audiences and readers ask ethical questions concerning the relationship(s) between subjectivity and communal identity formation. Twilight: Los Angeles, 1992, researched, written and originally performed by Anna Deavere Smith, serves as this article’s primary textual example of a monologic play. The play’s monologic form embodies ethical possibility through its attentiveness to multiple perspectives and intersubjective dialogue developed from Smith’s interviews following the aftermath of the Rodney King verdict. Because the violence against Rodney King (like the more recent murder of George Floyd) was recorded on video, the play’s monologic ethics also engage with, and sometimes against, technological evidence of institutional racism. Monologues, and especially soliloquies, function within larger dialogic plays as a mirror – a reflection of consciousness. These minor generic variations in dialogic plays here become Twilight’s primary organizing principle, thus transgressing traditional genre laws. Earlier twentieth-century monologic texts, by Beckett and others, resignified and problematized the soliloquy’s relationship to identity-formation. The paradigm of an isolated single subjectivity, such as Hamlet or even King Lear’s Edmund, is sedimented into classical form. Smith’s play, Twilight, like Shange’s monologic text, For Colored Girls, without one central protagonist, restructures and reframes the dramatic monologue to allow a closer look at the ethics of how we live with our own fragmented selves.

Value-saturated Education in Erzsébet Camps in Zánka, Hungary
Authors: Jancsák Csaba
Published: February 2021

The Erzsébet Camp in Zánka is located in the Balaton Highland, between Tihany and Badacsony. The Erzsébet Camps are one of the largest youth-project program in Hungary. Research data collection started in 2017, and it was carried out in three periods. The present study conducted analyses on a database compiled from findings of questionnaires administered to campers (2017, 2018 and 2019) and their chaperones (2018 and 2019). Data collection from the children and chaperones took place at the end of each camp shift and comprised of self-administered anonymous questionnaires with ten question blocks. The study conducts analyses of the database compiled from the main answers of more than 18,000 participants. Our research, exploratory in its nature, set out to compile the ”value map” of the Erzsébet Camps. The main focus of our interest was the added value and developmental effects of the camps with respect to campers. The another research question was what social values are transmitted and the preservation of which social values is supported by the Erzsébet Camps.
Community resilience in post-socialist rural areas
Authors: Papp Sándor
Published: February 2021

Resilience thinking has become an increasingly popular topic in both academic and policy-making circles due to its normative interpretation, which assumes that resilience is the opposite of vulnerability. Vulnerable groups, communities, settlements, regions and nations have a greater likelihood of facing more serious consequences in the event of unpredictable, negative shocks. Based on this view, in general, rural communities and regions can be considered more vulnerable and hence less resilient to unknown, negative events, as the subsistence of these communities is more closely linked to their environments rather than to people living in urban areas. This is further exacerbated by the path dependence of having a post-socialist past: the ‘legacy’ of socialism that, in many cases, includes a relatively disadvantageous position, backwardness and intensification of peripheralisation processes. While there is no consensus on the concept of resilience itself, there are several approaches and perspectives related to possibly detecting signs of its existence in rural communities. Our aim to present how the notion of resilience can be operationalised at the farm level in post-socialist contexts based on three different perspectives in order to contribute resilience thinking related to post-socialist discourses. We illustrate how rural community resilience may be conceptualised based on the example of the grape- and wine-producing communities of Soltvadkert, Hungary and the Minis-Maderat wine region, Romania. Based on our qualitative methodological results, it can be stated that the resilience of a community or group, its properties reflecting resilience can be interpreted in several ways, which is partly location-dependent, partly path-dependent, however, it is highly dependent not only on embedded structures but also on activities that are constantly reproduced by community members.
O scenicznym ożywianiu i potencjałach autobiograficznego archiwum na przykładzie wybranych chorwackich spektakli teatralnych
Authors: Abrasowicz Gabriela
Published: February 2021

Autobiographism has been noticeably conquering the Croatian theatre which results in specific artistic projects, mainly falling into the category of theatre of the real. This material calls for a description of strategies, functions and potentials. The most important here is the freedom to (re)construct identity – performativity – communication and interaction. The styling of an autobiographical archive and its extension into action allows adopting a new view and interpreting historical events and current social problems differently. This phenomenon is manifested in selected performances which involve staging a dramatic text, adapting prose or journalistic text, compiling and processing various cultural texts, incorporating the performers’ confessions and observations, and developing documentary material. Descriptions of the latest performances confirm reactivity of the theatre, its power to concertize and subjectivize, as well as to model the audience’s attitudes.
Archiving in the Face of Erasure: the Idea of the “Post-German” Archive
Authors: Ćwiek-Rogalska Karolina
Published: February 2021

The article introduces the notion of the “post-German” archive as an idea for further research on the erased cultures of Central Europe. The author questions the hierarchical and top-down structure of the institutionalized archive. Instead, she proposes to understand the “post-German” archive as an inclusive conception. It would incorporate various narratives, languages, and perspectives. In this way, the canonization of given motives can be avoided. The author pays special attention to the responsibility of the researcher. She illustrates the theoretical framework with examples from Polish and Czech archival practices.

Published: February 2021

Teacher education has been recognized increasingly as a profession that fundamentally differs from teaching pupils in schools. This has resulted in teacher educator development programs which address the uniqueness of the profession. In this article we depart from this recognition of teacher education as a profession outlining the specifics of teacher education, and we describe a professional development program for teacher educators run in the Netherlands. We describe its building blocks and three design principles – narrative inquiry, dialogue and self-study – and illustrate their value by examples of evaluations taken from the program.

CULTURA E DIRITTO AMBIENTALE
Authors: Perra Livio
Published: February 2021

RIASSUNTO Nel presente articolo l’autore pone l’accento sullo stretto legame che intercorre tra il diritto e la cultura. Il mondo del diritto allo stesso tempo trova spunti di riflessione nella tradizione e diventa manifestazione della cultura. In materia di diritto ambientale questa connessione trova il proprio apice nei diritti bioculturali e nei diritti delle entità naturali non umane. Nei nuovi sistemi di protezione ambientale poggiati sulle solide basi della cultura, l’autore indaga anche il nuovo ruolo dell’essere umano. Lo scopo del presente lavoro consiste nel dimostrare come, partendo dalla cultura, si possa giungere all’innovazione giuridica.

Fundamental thermodynamic properties of the synthetic analog of the famatinite mineral - Cu3SbS4 were studied on the basis of electromotive force (EMF) measurements. The EMF of the concentration chains relative to the Cu electrode with a solid electrolyte was measured for the alloys from the Cu3SbS4 + Sb2S3 + S phase region at 300-380K temperature interval. Based on measurement data, the relative partial thermodynamic functions of copper in alloys, the standard thermodynamic functions of formation, as well as, the standard entropy of the Cu3SbS4 ternary compound were calculated for the first time.

Purpose: to determine the relationship between the level of sensorimotor reactions and indicators of physical fitness in young taekwondo fighters. Material and methods. The following methods were used in the study: analysis of scientific and methodological information, Internet sources and generalization of best practices, psychophysiological research methods, methods of mathematical statistics. The study involved 16 young taekwondo fighters, aged 8-9 years. The pedagogical research was conducted in three stages. The first stage was devoted to the assessment of sensorimotor reactions, the second to the assessment of physical fitness of young taekwondo fighters, and the third stage was a correlation analysis between the indicators of sensorimotor reactions and indicators of physical fitness. Results: Based on the analysis of scientific and methodological information, Internet sources and generalization of best practices, it was found that one of the many tasks that coaches solve in the training process of young taekwondo fighters is to identify opportunities and inclinations to achieve high sports results in the future. The results of the study indicate the homogeneity of simple and complex reactions (from 5,20 % to 10,79 %), in addition to the index of complex response to a moving object, which has a high coefficient of variation (38,6 %). Indicators in tests that reflect specific perceptions also have a high coefficient of variation (from 16,5 % to 38,7 %). This can be explained by the fact that this type of reaction is of great importance in martial arts and the best results in these tests may indicate certain abilities of some athletes. Analysis of the results of physical fitness showed that in almost all tests there is a large variability of values (from 13,89 % to 96,02 %). The lowest value of the coefficient of variation was noted in the test «Shuttle running 3×6 meters» (V=7,77 %). Conclusions. Correlation analysis of the relationship between the level of manifestation of sensorimotor reactions with indicators of physical fitness showed that the values obtained by performing the test «Simple visual-motor reaction» have statistically significant relationships with the test «Shuttle running 3×6 meters» (r=0,51), and the values (test «Simple motility») statistically significantly interact with the values shown by young athletes in the test «Complex relay 15 meters» (r=-0,51). Other tests showed a weak level of correlation (r<0,5). The study of the relationship between the level of manifestation of sensorimotor reactions and physical fitness allowed to determine the level of interaction of the mechanisms of movement control of young taekwondo fighters and to form directions for improving the quality of the training process.

Purpose: with the help of a questionnaire, to analyze the criteria for evaluating judo judges for performance indicators at competitions. Material and methods. During the research the following methods were used: theoretical analysis and generalization of literature sources, Internet data, questionnaires, generalization of theoretical and practical experience of specialists in the field of martial arts, methods of mathematical statistics. A questionnaire survey of judo judges was conducted. The study involved 30 judo judges of the international category (3 men – 10 %) of the national category (15 people – 50 %) and the first category (12 people – 40 %). Results: the analysis of the conducted survey of judo judges on the basis of 50 evaluation criteria for the performance of judges in competitions revealed the main 11 criteria that are in the opinion of most experts the most effective. Thus, 11 criteria were distributed among specialists of international, national and first categories of judges as follows: in the first place - professional ethics and discipline 1,33; in second place - the appearance of 1,66; in third place - knowledge of the rules and the ability to use them 3,66; in fourth place - is the clarity of commands and gestures 4,66; in fifth place - moving on the tatami and choosing the correct position 5,00; in sixth place - interaction with judges 6,67; in seventh place - the ability to correctly and timely assess errors 7.66; in eighth place - the ability to accurately and timely assess technical actions 8,00; in ninth place - psychological stability 8,33; in tenth place - the reaction to the situation 8,66; on the eleventh place - the ability to use technical means 10,33. Conclusions. Thus, the survey of judges' categories from the 50 proposed criteria revealed 11 most practical criteria by which it is possible to evaluate the work of judges in competitions. As a result of the questionnaire survey, most experts put professional ethics and discipline in the first place; second place - appearance; third place - knowledge of the rules and the ability to use them.

The greater mole-rat (Spalax microphthalmus) and humans: facets of interaction in the Middle Volga Region
Authors:   Mordovian National Research State University (Saransk, Russia), Andreychev Alexey
Published: February 2021

In Mordovia, there is a relict local population of the greater mole-rat (Spalax microphthalmus). Similar isolated populations of the greater mole-rat have been preserved only in a few regions of the Volga Region. They are confined to refugia of steppe vegetation. In these regions, the greater mole-rat needs protection. However, people violate the animals' habitats and destroy them. This is also typical for Mordovia, where a stable small population has existed for a long time. The aim of the paper was to study changes in the impact of human activity on the population of the greater mole-rat at the northern border of the species’ range. The impact of human activity on one of the settlements in the local population was studied. This territory was a hotbed from which there was a settlement to adjacent suitable sites. Since 1974, this territory has been a complex natural monument “Levzhenskiy Landscape Reserve.” Twenty-five individuals (13% of the total population in the region) lived in the area of human impact. The settlement of animals in the direction of the city due to plowing the steppe meadow was revealed. It was noted that the greater mole-rat appeared near roads, houses, and gardens where they had not been recorded before. Individual mounds were found between the extreme houses of the village of Levzhenskiy and this plowed area. In addition, fresh mounds from one burrowing system were found in a narrow strip (3 meters) between the road and the plowed area. In both cases, we are talking about individual survivors. In comparison with cattle grazing, plowing of a steppe meadow is a significant negative impact on the greater mole-rat since it is the destruction, first of all, the food base. Earlier, greater mole-rats did not migrate massively from their plots because of cattle grazing. This impact has not only changed the state of the population, but may be one of the reasons for the disappearance of the population in general. Paleontological findings within the city limits confirm the former wider distribution of the greater mole-rat.

Published: February 2021

Disagreements, including those between residents and attending physicians, are common in medicine. In this Ethics Rounds article, we present a case in which an intern and attending disagree about discharging the patient; the attending recommends that the patient be hospitalized longer without providing evidence to support his recommendation. Commentators address different aspects of the case. The first group, including a resident, focus on the intern’s potential moral distress and the importance of providing trainees with communication and conflict resolution skills to address inevitable conflicts. The second commentator, a hospitalist and residency program director, highlights the difference between residents’ decision ownership and attending physicians’ responsibilities and the way in which attending physicians’ responsibilities for patients can conflict with their roles as teachers. She also highlights a number of ways training programs can support both trainees and attending physicians in addressing conflict, including cultivating a learning environment in which questioning is encouraged and celebrated. The third commentator, a hospitalist, notes the importance of shared decision-making with patients and their parents when decisions involve risk and uncertainty. Family-centered rounds can facilitate shared decision-making.
