Published: December 2021

The existing safety analysis methods for the assessment of the aerostatic stability of long-span symmetry cable-stayed bridges have difficulties in meeting the requirements of engineering applications. Based on the finite element method and the inverse reliability theory, an approach for the probabilistic safety analysis of the aerostatic instability of long-span symmetry cable-stayed bridges is proposed here. The probabilistic safety factor of aerostatic instability of long-span symmetry cable-stayed bridges was estimated using the proposed method, with Sutong Bridge as an example. The probabilistic safety factors for the aerostatic instability of Sutong Bridge were calculated using the finite element inverse reliability method, based on the FORM approach. The influences of the mean value and the coefficient of variation of random variables, as well as the iterative step length of finite difference, on the probabilistic safety factors of aerostatic instability of Sutong Bridge were analyzed. The results indicated that it is necessary to consider the uncertainties of random variables in probabilistic safety factor assessments of aerostatic instability in cable-stayed bridges using the proposed method, which could be recommended for the assessment of safety factors involved in the aerostatic instability of long-span symmetry cable-stayed bridges. The randomness of the parameters had an important influence on the probabilistic safety factor of the aerostatic stability of Sutong Bridge. Neglecting the randomness of these parameters may result in instability of the structure.

Published: December 2021

Stephanodiscus makarovae, a taxon originally described from Russia, is morphologically similar to several other taxa within Cyclostephanos, namely C. invisitatus, C. delicatus and C. tholiformis. However, it has not yet been transferred into Cyclostephanos, perhaps due to the difficulty in identifying it, as its original description is available only in the Russian language. To investigate its morphology, a detailed morphological comparison of S. makarovae and C. invisitatus was done from 286 SEM micrographs of 12 monoclonal strains. We performed a three-gene phylogenetic analysis with strains from eight additional taxa to independently confirm the position of S. makarovae. The morphology of S. makarovae shows key features of the genus Cyclostephanos and this attribution is supported by the phylogeny. Here we propose the transfer of the taxon S. makarovae to Cyclostephanos, considering the morphological and molecular data. According to both the molecular and morphological data, C. delicatus has a unique position within the genus; S. makarovae and C. invisitatus are morphologically very similar but genetically distinct. Furthermore, based upon the results, it was possible to reassign the authority of the transfer of S. delicatus into Cyclostephanos.

Published: December 2021

Small ruminant lentiviruses (SRLVs) exist as populations of closely related genetic variants, known as quasispecies, within an individual host. The privileged way of SRLVs transmission in goats is through the ingestion of colostrum and milk of infected does. Thus, characterization of SRLV variants transmitted through the milk, including milk epithelial cells (MEC), may provide useful information about the transmission and evolution of SRLVs. Therefore, the aim of this study was to detect SRLVs in peripheral blood leukocytes (PBLs) and milk epithelial cells of goats naturally infected with SRLVs and perform single nucleotide variations analysis to characterize the extent of genetic heterogeneity of detected SRLVs through comparison of their gag gene sequences. Blood and milk samples from 24 seropositive goats were tested in this study. The double immunolabeling against p28 and cytokeratin demonstrated that milk epithelial cells originated from naturally infected goats were infected by SRLVs. Moreover, PCR confirmed the presence of the integrated SRLVs proviral genome indicating that MECs may have a role as a reservoir of SRLVs and can transmit the virus through milk. The blood and MEC derived sequences from 7 goats were successfully sequenced using NGS and revealed that these sequences were genetically similar. The MEC and blood-derived sequences contained from 3 to 30 (mean, 10.8) and from 1 to 10 (mean, 5.4) unique SNVs, respectively. In five out of seven goats, SNVs occurred more frequent in MEC derived sequences. Non-synonymous SNVs were found in both, PBLs and MEC-derived sequences of analyzed goats and their total number differed between animals. The results of this study add to our understanding of SRLVs genomic variability. Our data provides evidence for the existence of SRLVs quasispecies and to our knowledge, this is the first study that showed quasispecies composition and minority variants of SRLVs present milk epithelial cells.

Published: December 2021

A 15-month-old intact female Pitbull was referred because of recurrent, episodic, self-limiting, excitement-induced bleeding from nontraumatised skin. No abnormalities were detected upon physical examination. Subsequently, the dog went for a walk under the direct supervision of one of the authors, became overexcited and, after approximately five minutes, bloody liquid, with a patchy distribution, appeared along the hair shafts of the face and neck. The affected skin was congested, partially blanching on diascopy and bloody liquid was oozing from the follicular openings. Urticaria, dermographism and hypertension were excluded, the complete blood count and coagulation profile were within the reference ranges and an analysis of the bloody exudate confirmed its blood components. The cutaneous bleeding of the dog followed a self-limited course, with no episodes during the last two years. Clinical and laboratory findings and the long-term evolution of this dog bear striking similarities to haematidrosis, a rare human disease of multifactorial aetiology and equivocal pathogenesis.

Published: December 2021

The Upper Cretaceous carbonates along the Zagros thrust-fold belt “Harir-Safin anticlines” experienced extensive hot brine fluids that produced several phases of hydrothermal cements, including saddle dolomites. Detailed fluid inclusion microthermometry data show that saddle dolomites precipitated from hydrothermal (83–160 °C) and saline fluids (up to 25 eq. wt.% NaCl; i.e., seven times higher than the seawater salinity). The fluids interacted with brine/rocks during their circulation before invading the Upper Cretaceous carbonates. Two entrapment episodes (early and late) of FIs from the hydrothermal “HT” cements are recognized. The early episode is linked to fault-related fractures and was contemporaneous with the precipitation of the HT cements. The fluid inclusions leaked and were refilled during a later diagenetic phase. The late episode is consistent with low saline fluids (0.18 and 2.57 eq. wt.% NaCl) which had a meteoric origin. Utilizing the laser ablation U-Pb age dating method, two numerical absolute ages of ~70 Ma and 3.8 Ma are identified from calcrete levels in the Upper Cretaceous carbonates. These two ages obtained in the same level of calcrete indicate that this unit was twice exposed to subaerial conditions. The earlier exposure was associated with alveolar and other diagenetic features, such as dissolution, micritization, cementation, while the second calcrete level is associated with laminae, pisolitic, and microstromatolite features which formed during the regional uplifting of the area in Pliocene times. In conclusion, the hydrothermal-saddle dolomites were precipitated from high temperature saline fluids, while calcrete levels entrapped large monophase with very low salinity fluid inclusions, indicative for a low temperature precipitation from water with a meteoric origin.

Despite spending ample resources and procedural development in flood management, flood losses are still increasing worldwide. The losses caused by floods and costs incurred on management are two components of expected annual damages (EAD) due to floods. This study introduces a generalized approach for risk-based design where a range of probable floods are considered before and after a flood mitigation measure is implemented. The proposed approach is customized from the ISO Guide 31000 along with additional advantages of flood risk visualization. A Geographic Information System (GIS)-based design of a flood-protection dike is performed to exhibit the risk redistribution. The Chenab River is selected for the existing dike system. Detailed hazard behaviour and societal vulnerability are modelled and visualized for a range of all probable floods before and after the implementation of flood-protection dikes. EAD maps demonstrate the redistribution of induced and residual risks. It can be concluded that GIS-based EAD maps not only facilitate cost-effective solutions but also provide an accurate estimate of residual risks after the mitigation measures are applied. EAD maps also indicate the high-risk areas to facilitate designing secondary measures.
Glacial Lake Evolution (1962–2018) and Outburst Susceptibility of Gurudongmar Lake Complex in the Tista Basin, Sikkim Himalaya (India)

Published: December 2021

The Sikkim Himalayan glaciers and glacial lakes are affected by climate change like other parts of the Himalayas. As a result of this climate variability in the Sikkim Himalaya, a detailed study of the Gurudongmar lake complex (GLC) evolution and outburst susceptibility assessment is required. Glacial lake volume estimation and lake outburst susceptibility assessment were carried out to reveal different characteristics for all four lakes (GL-1, GL-2, GL-3, and GL-4) from the lake complex. Each of these lakes has a moderate to very high potential to outburst. As the dam of GL-1 provides no retention capacity, there is a very high potential of a combined effect with the sudden failure of the moraine-dams of GL-2 or GL-3 located upstream. Temporal analysis of GLC using optical remote sensing data and in-field investigations revealed a rapidly increasing total lake area by ~74 ± 3%, with an expansion rate of +0.03 ± 0.002 km2 a−1 between 1962 and 2018 due to climate change and ongoing glacier retreat. The overall lake area expansion rates are dependent on climate-driven factors, and constantly increasing average air temperature is responsible for the enlargement of the lake areas. Simultaneously, changes in GLC expansion velocity are driven by changes in the total amount of precipitation. The deficit in precipitation probably triggered the initial higher rate from 1962 to 1988 during the winter and spring seasons. The post-1990s positive anomaly in precipitation might have reduced the rate of the glacial lake area expansion considerably.

This paper discusses the origin and evolution of saline springs in north and central Laos, based on chemical and stable isotopes (δD, δ18O, δ11B, and δ37Cl). All the saline springs in this study are of the Na–Cl geochemical type. The geochemical and water isotope values suggest that the saline springs in this study are mainly derived from meteoric water and/or ice and snow melt from the surrounding mountains and that they also experienced strong evaporation and intense rock–water interactions. The ionic ratios, characteristic coefficients, ternary Ca–SO4–HCO3 phase diagrams, and saturation indices of minerals show that the dissolution of halite, sulfate, and carbonate rocks may be the solute sources for saline springs in this study, whereas the underground brines in the Thakhek potash mining area are geochemically influenced by the dissolution of carnallite and sylvite. The global geothermal δ11B–Cl/B relationship and δ11B values (5.50 to 36.01‰) of saline springs suggest a continental origin of B. This B is most likely derived from marine carbonate rocks and marine evaporates (gypsum and halite) of the late Cretaceous, which is similar to the saline springs of the Nangqen–Qamdo–Simao Salt Basin. The δ37Cl value (−0.12 to +0.79) and the Cl/Br ratio (4076 to 9853) show that dissolution of late cretaceous marine halite layers, atmospheric precipitation, and water–rock interactions between volcanic rocks, mudstones, and sandstone can restrict the δ37Cl values in saline springs. Results from silica geothermometry and multi–mineral equilibrium diagrams indicate that the reservoir temperatures for the saline springs range from 87–137 °C and experience deep circulation. Hydrochemical characteristic coefficients suggest that saline springs in the Muang Say basin may have leached sylvinite and carnallite and that the potash exploration prospect in this area is relatively good.
Development of a Periphytic Diatom-Based Comprehensive Diatom Index for Assessing the Trophic Status of Lakes in the Lower Reaches of the Yangtze River, China

Published: December 2021

Periphytic diatoms play important functional roles in aquatic ecosystems. Their community compositions are widely used in water quality monitoring due to their wide distribution, short reproductive cycles, and sensitivity to environmental changes. In this study, 116 samples of periphytic diatom samples were collected from lakes in the lower reaches of the Yangtze River. The weighted average without tolerance down-weighting regression method was used to develop total phosphorus (r2 = 0.661), total nitrogen (r2 = 0.699), and chemical oxygen demand (r2 = 0.423) models, and the optimal and tolerance values of 78 periphytic species were calculated. Then, a new index, the comprehensive diatom index (CDI), was established on the basis of the optima and tolerances of these 78 species concerning the three environmental variables (TP, TN, and COD) to assess the water trophic status of the lakes in this region. According to the CDI, the trophic statuses of 8, 17, 23, 30, 22, and 14 sample sites were oligotrophic, mesotrophic, light eutrophication, moderate eutrophication, heavy eutrophication, and ultra-eutrophication, respectively. The CDI was more strongly correlated with the conductivity, pH, TP, TN, COD, and TDS than other diatom indices. These results demonstrate that the CDI is a useful metric for assessing the water trophic status of the lakes in the lower reaches of the Yangtze River.
Vortex Dynamics Analysis of Internal Flow Field of Mixed-Flow Pump under Alford Effect
Authors: Li Shuo , Li Wei , Ji Leilei , Shi Weidong , Agarwal Ramesh K.
Published: December 2021

A multi-region dynamic slip method was established to study the internal flow characteristics of the mixed-flow pump under the Alford effect. The ANSYS Fluent software and the standard k-ε two-equation model were used to numerically predict the mixed-flow pump’s external characteristics and analyze the forces on the impeller and guide vane internal vortex structure and non-uniform tip gap of the mixed-flow pump at different eccentric distances. The research results show that the external characteristic results of the numerical calculation are consistent with the experimental measurement. The head error of the design flow operating point is about 5%, and the efficiency error is no more than 3%, indicating the high accuracy of numerical calculation. Eccentricity has a significant influence on the flow field in the tip area of the mixed-flow pump impeller, the distribution of vortex core in the impeller presents obvious asymmetry, the strength and distribution area of the vortex core in the small gap area of the tip increase obviously, which aggravates the flow instability and increases the energy loss. With the increase of eccentricity, the strength and number of vortex core structures in the guide vane also increase significantly, and obvious flow separation occurs near the inlet of the guide vane suction surface on the eccentric side of the impeller. The circumferential distribution of L1 and L2 values represents the friction pressure gap in the eccentric state, and the eccentricity has a more noticeable effect on L1 and L2 values at the small gap; With the increase of eccentricity, the values of vorticity moment components L1 and L2 increase, and the Alford moment on the impeller increases. The leading-edge region of the blade is the main part affected by the unstable torque of the flow field. With the increase of eccentricity, the impact degree of tip leakage flow deepens, and the change of the tip surface pressure is the most obvious. The impact area of tip leakage flow is mainly concentrated in the first half of the impeller channel, which has an impact on the blade inlet flow field but has little impact on the blade outlet flow field.

Features of the work of the UK healthcare during the fight against the epidemic
Authors: Frolova Elena Vladimirovna
Published: December 2021

Due to their isolation and the ability to limit communication with the outside world, many island states managed to quickly localize the spread of the epidemic, as a result of which the incidence and mortality rates were much lower than in the whole world. So, in Australia, the number of detected cases as of the beginning of autumn 2021 was about 50,000, of which 993 cases had fatal outcomes (ranking 118th in the world); in New Zealand, a total of 3,380 cases of the disease were detected (of which 26 were fatal); on the island of Greenland a total of 326 cases of the disease without deaths were registered. At the same time, the UK in terms of the number of cases came close to the mark of 7 million people, as a result of which it ranked 6th in the world. It was in Great Britain that the «delta» strain was one of the first registered, which caused many states to close their air borders with Great Britain. Only according to official statistics, in the UK, the coronavirus infection was registered in every tenth inhabitant of the country. At the same time, the UK occupies one of the leading places in the world in terms of vaccination rates — as of September 1, 70 % of the population received two doses of the vaccine. A feature of English healthcare is its statehood — funding for the needs of medicine is carried out not at the expense of insurance premiums, but at the expense of tax deductions. The central government allocates state funds to the Ministry of Health, which is responsible for further allocation of funds. Despite the fact that in July 2021 the daily number of newly diagnosed cases of the disease was one of the highest in the world, the government of the country announced the lifting of all quarantine restrictions from July 19.

Published: December 2021

Breeding work with dairy cattle in the Kurgan region is aimed at breeding animals that combine the adaptive properties and valuable traits of cattle of Black-and-White breed with a high proportion of genes of Holstein breed. Such animals are characterized by high productivity and suitability for intensive technology of their housing. The purpose of the research was to determine the indicators of milk productivity of first-calf heifers of different generations of Holstein breed, imported to the pedigree farms of the Kurgan region, as well as to determine the degree of realization of the genetic potential of animals. Scientific research has been carried out in the herd of CJSC “Glinka” (Kurgan), where highly productive cattle of Black-and-White and Holstein breeds are bred. The subject of research was the first-calf heifers of the imported Holstein breed of German selection of different generations, as well as the herdmates of Black-and-White breed. It has been found that the realization of the genetic potential for milk yield in Holstein cows of German breeding was higher and amounted to 76,4 %, in cows of Black-and-White breed 69,9 %. The highest milk yield for 305 days of lactation has been observed in the second generation of Holstein heifers 8905 kg, which exceeded the milk yield of herdmates of the second and third generations by 113 kg or 1,26 % and 174 kg or 1,95 %, respectively. The mass fraction of fat in German Holsteins of different generations ranged from 3,99 to 4,21 % (P < 0,001), while the mass fraction of protein in the milk of first-calf heifers varied slightly in the range from 3,18 to 3,20 %. In terms of live weight, the animals of the third generation slightly exceeded the herdmates of the 1st and 2nd generations by 19 kg or 3,25 % and 20 kg or 3,43 %, respectively. The largest profit has been received from the first-generation first-calf heifers of Holstein breed of German selection, where the level of profitability of milk production was 50,7 %, which was higher than that of the herdmates of the second and third generations by 3,9 and 7,9 %, respectively.

Published: December 2021

The results of investigations on the formation of high-yielding haymaking fields with the sowing of perennial legumes with different methods of processing the sod of degraded hayfields have been presented in the paper. The purpose of the work was to determine the most effective methods that contribute to increasing the yield and feed quality of degraded haymaking. The most effective methods that contribute to increasing the yield, feed quality and productive longevity of degraded haymaking have been determined. The content of perennial legumes in the herbage was registered: in the variant with plowing of turf it was 88 %, with milling – 80, with disking – 70 %. The highest yield has been obtained on the variant with the radical improvement 17,3 t/ha herbage and 3,64 t/ha of dry weight, which exceeded the indicators of the control variant by 3,6 times. It has been revealed that with the radical improvement of degraded haymaking (plowing + disking), the yield of feed units reached 1,74 t/ha, digestible protein – 0,25 t/ha, the amount of digestible protein per 1 feed unit was 140 g. These indicators during the sod disking were: 1,55 t/ha, 0,22 t/ha and 135 g, respectively. When strip-seeding of perennial legumes, the variant with the width of the treated strip of 60 cm has been distinguished. The collection of feed units amounted to 1,61 t/ha, of digestible protein – 0,18 t/ha. In the control variant (degraded haymaking), the collection of feed units was 0,38 t/ha, of digestible protein-0,025 t/ha. An economic assessment of the methods of improving degraded haymaking has shown that strip sowing of perennial legumes turned out to be the most effective method of improvement in the forest-steppe zone in Western Siberia. The net income depending on the option of strip sowing amounted to 3751–4278 rubles/ha, the level of profitability – 71–87 %. During the radical improvement, the economic indicators were slightly lower – 3959 rubles/ha and 57 %, respectively.

CONFIGURATION OF PROFESSIONAL LEARNING FOR PSYCHOPEDAGOGIC ADVISORY FROM THE INTERDISCIPLINARY APPROACH

ABSTRACT

The initial formation process for the Bachelor of Education. Pedagogy-Psychology demands the apprehension of psychopedagogical advisory to managers and teachers as a way of professional acting, in correspondence with the object of the profession and the spheres of action. In the evaluation of the understanding and execution of the role of psycho-pedagogical advisor, inadequacies are detected in the training process that limit the theoretical-methodological configuration of this professional process. In this direction and as an answer to this problem it is proposed, from an interdisciplinary focus, the configuration of professional learning for psychopedagogical advisory in order to favor the domain of the action mode from the academic, laboral and research relationship. Theoretical methods are used from a systemic perspective: analytical-synthetic, historical-logical and empirical: observation, survey, interview and documentary analysis. The results express the integrating dialectic of the process of formation of psychopedagogical counseling and its contextualized application in educational situations.

Las redes de comunicaciones que en la actualidad representan una herramienta muy importante en el proceso de comunicación a nivel mundial. En los últimos años se considera a las redes definidas por software como uno de los aspectos más representativos, y que con el pasar del tiempo ha despertado el interés de las organizaciones en general. En nuestro medio, específicamente en las instituciones de educación superior, se vienen realizando diversos estudios relacionados a la temática de Redes definidas por Software (SDN), desde evaluaciones de rendimiento entre redes tradicionales y SDN, hasta implementaciones de prototipos de redes, son algunos de los ejemplos más comunes que durante los últimos años han sido objeto de estudio. El presente trabajo de investigación pretende realizar una revisión bibliográfica sobre los diferentes estudios relacionados al paradigma de redes definidas por software que las Universidades ecuatorianas han realizado durante los últimos años. Si bien es cierto existen numerosos estudios sobres las SDN por parte de las Universidades ecuatorianas, la mayoría de estos son realizados en ambientes de simulación con la ayuda de software especializado, por lo que es importante materializar dichos trabajos o llevarlos a escenarios reales con la finalidad de poder tener una perspectiva más exacta de sus ventajas y desventajas frente a las redes tradicionales.

З врахуванням особливостей політичної ситуації та традиції України пропонується для застосування в ній такі форми сучасної демократії як деліберативна (дорадча) (за Д. Хелдом), яка відповідає переважно однорідному суспільству, а також «спільницька» (комунітарна) форма (за А. Лейпхартом), яка відповідає багатоскладному суспільству. Розглянуті їх переваги і недоліки, а також основні фактори та умови розвитку демократії в країні у цілому.
SELF IDENTIFICATION-OF THE UKRAINIANS TROUGH PINING FOR THEIR NATIVE LAND (ON THE MATERIAL OF FOLK ART)
Authors: TREHUBOV Dmytro , TREHUBOVА Iryna
Published: December 2021

The scientific novelty of this study is determined by the acute topicality of the studies concerning self-identification of the Ukrainians. Leaving the native land allows a person to better understand his/ her inner self. In the creative heritage of Ukraine, there are many mentionings of the types of separation from the native land and the reflection of personal attitude to it. Manifestations of this cultural phenomenon in different types of literary creativity are given close attention. The causes that add to the pining for the native land are classified, and their reflection in the literary heritage of the Ukrainian people is revealed. It is emphasized that for Ukraine, more often than for other states, this issue has repeatedly become relevant at different times. A new type of separation from the native land has been identified: the forced loss of the native language on one’s own land. It is emphasized that some songs contain direct instructions to the listener on the principles of maintaining national identity. For example, the found version of the song “The falcon and eagle became friends” contains a new stanza with the request: “Teach my children / In a foreign land / not to seek for happiness”. In the context of modern Ukrainian cultural background pining for the native land becomes topical, and the concept of “evshan-potion” is deemed really important. In general, this work shows that the cultural identity of Ukrainians has historical evidence, which is enshrined in folk songs and literary heritage. These results allow us to clarify the foundations of the cultural identity of the Ukrainians.
Teaching Research Methods and the Supervision of Undergraduate Projects: Seeking Practical Improvements to a Complex Process
Authors: Mitchell Anthony , Rich Martin
Published: December 2021

This paper develops a review of teaching research methods and student supervisor relationships, first presented to ECRM20. Last year we tested an extensive literature review with a survey of undergraduate business students, this has now been supplemented with further survey data, interviews and a focus group.  This supplementary data has deepened our understanding of the issues and has largely reinforced the findings from the previous paper. At a time when some schools are moving content on-line and seeking new forms of assessment, there is a need to ensure that research continues to fulfil a contribution towards intellectual and practical understanding. Detailed analysis has explored the extent to which the teaching of research methods within a taught degree course and the completion of an individual project has proved effective. Value perceived by the students and supervisors of a major project has been confirmed to influence both success for a candidate at an interview as well as providing a skill set suitable for longer term employment. Learning ‘skills for life’ was suggested by the students.. The extent to which students and supervisors engage was explored and opportunities for improvement are reported. The importance of adding an element of fun to the process was also raised. Little evidence of supervisors receiving training was found, Feather et al (2010, 2013) and a challenge continues to be the extent to which supervisors are fully briefed on the required dissertation process.  In practice, supervisors rely on their own prior experience and this can contribute to an uneven quality of experience for students. Conclusions on the undergraduate data are developed for two specific research questions and next steps for improvement at the school are outlined for the Business School to consider.

The influence of poetic and musical rhythm on the perception and comprehension of an educational text by an Ancient Greek student
Authors: Kolyshko Alexandr М.
Published: December 2021

The article presents the results of the historical and psychological reconstruction of educational reading in an Ancient Greek school. The purpose of this reconstruction was to identify the psychological mechanisms of influence of the musical and poetic rhythm on the student's personality, to determine the pedagogic potential of the poetic text as a means of raising, to reveal the psychological mechanisms of the activity of the text as a subject of educational reading. The educational effects of the rhythm of the mythological and poetic text in the context of the formation of the socio-cultural identity of an Ancient Greek student are revealed. The psychological mechanisms of the participation of poetic and musical rhythm in the organisation of the practice of reading in an Ancient Greek school are described. It is noted that the poetic rhythm of the text suggests a special way of participating in the teacher's educational reading. Based on the reconstruction, it is concluded that the rhythmically intense educational mythological and poetic text has the ability to evoke an emotional response in the student, influence his unconscious attitudes, and impose emotional and semantic dominants of perception and understanding of what is written. The most important task of modern education is found in the formation of student's sense of rhythm in the process of educational reading. It is noted that this sense of rhythm in a modern school can be formed by referring to educational texts and texts used in youth culture.
Theoretical and practical researches of interactive method in learning a foreign language
Authors: Barabanova Elena I.
Published: December 2021

The article discusses the features of using interaction as methodological basis of organisation of interactive approach and its role in interactive learning. The author compares different points of view and suggests methodological assumptions about the reorganisation of the traditional approach to the practice of learning how to work out the skills of interpersonal communication. The author notes that interactive approach means interaction of all members of learning process which helps to exchange authentic information in a foreign language. The author gives methodological grounds developing skills of informational exchange in a foreign language and possessing experience of communication using interactive exercises. The article analyses principles of interactive learning a foreign language via interaction which results in the development of social processes in the society. The author considers it conforming that in the past years in the methodology of teaching foreign languages, there has been a tendency to change the position and to move from the communicative approach to its variety – the interactive approach, since interactive learning of a foreign language proposes the usage of training, role and business-like games, competitions, performances, warming-up, discussions, brainstorming, which will enlarge the level of interaction in a foreign language. The author believes that interactive learning will permit to solve many problems in the development of communicative skills and promote success in learning a foreign language which is the aim of its usage.
The Social Mind-set Model potentially explains varying societies’ responses to social and criminal behavior
Authors: Miller Monica , Westbrook Amber
Published: December 2021

Many countries face similar social issues, but adopt dramatically different solutions. This variation could be because countries have different social mind-sets (SMS), which explain why a certain policy response is adopted. The Social Mind-set Model (“SMS Model”) is a modest addition to the frameworks of Blumer (1971) and Kingdon (2003), who explain how and when the policy process begins. The SMS Model proposes six factors that influence the SMS of a society, which in turn shapes policy processes described by Blumer and Kingdon. These include society’s: 1) high-profile events and social movements, 2) economic-political-legal situation, 3) cultural beliefs and practices, 4) use of research, 5) preference for justice principles, and 6) attributions for behavior. This cross-cultural analysis uses examples from multiple countries. We conclude with a challenge for researchers to continue this line of research, to test the model, to find more model factors and directly test the model’s assumptions.
“El trabajo de la carpintería siempre es malo para la salud”: Antecedentes y aportes antropológicos al estudio de los procesos de salud-enfermedad de los trabajadores de la construcción
Authors: Philipp Gretel
Published: December 2021

Este artículo presenta una aproximación al estudio de los procesos de salud-enfermedad de los trabajadores de la construcción rosarina. Caracterizada como una industria muy heterogénea, precaria y peligrosa, la bibliografía especializada confiere una centralidad a los riesgos, los accidentes, así como a la seguridad y la prevención. La predominancia de las Ingenierías y la Medicina en el estado de la cuestión revela una determinada construcción médico técnica de la problemática que se centra en lo individual y lo biológico, reproduciendo y trasladando al área laboral la concepción del modelo médico dominante. Esta perspectiva fue cuestionada en América Latina desde los años 70 fundamentalmente por la Medicina Social, que nutrió asimismo a una cantidad de abordajes antropológicos y conformó un arsenal teórico que aún hoy sigue siendo fundamental para una antropología de los procesos de salud-enfermedad de los y las trabajadoras.

En el siguiente texto se sintetizan los estudios que prevalecen en el campo de la salud en la construcción; se reconstruyen los aportes realizados desde la antropología al problema de la salud de los trabajadores; y se presentan algunas reflexiones analíticas fruto de un trabajo etnográfico desarrollado en dos obras en construcción de la ciudad de Rosario entre los años 2009 y 2019.
Afrodescendencia, racismo y antropología: reflexiones a partir de instancias formativas en las aulas de la Universidad Nacional de Rosario
Authors: Broguet Julia
Published: December 2021

En el cursado de la carrera de Antropología de la Universidad Nacional de Rosario entre 1999-2004 aproximadamente, los estudios sobre las poblaciones afrodescendientes en las Américas y las discusiones derivadas de la variable racial, con relación a estas poblaciones, fueron poco tratados. En este trabajo queremos problematizar esta escasez bibliográfica y el tipo de abordaje de algunos de estos debates durante nuestra experiencia formativa generacional (Achilli, 2011) a la luz de una adscripción que realizamos desde el 2017 (y actualmente) en la materia Sistemas Socioculturales Americanos de tal carrera. A partir de este contraste iremos recuperando experiencias e intercambios surgidos del espacio áulico, en diferentes periodos y materias de la carrera, en pos de cuestionar factores que, en distintos niveles contextuales, entendemos provocaron que en esta institución de educación superior estuvieran casi totalmente ausentes los estudios afrodescendientes y el debate en torno a las continuidades/superposiciones entre raza/etnicidad, como un elemento conexo. Las breves reflexiones que reúne el presente escrito pretenden aportar a un intercambio crítico sobre la formación antropológica en la UNR.
