Gendered Experiences of Appearance-related Perks and Penalties in Finnish Labor Markets
Authors: Kukkonen Iida , Sarpila Outi
Published: September 2021

Physical appearance is generally associated with considerable labor-market sanctions, and appearances are thought to be of particular importance in the feminine service sector. However, little is known about workers’ experiences of appearance-based perks and penalties in Nordic labor markets. Drawing on literature on aesthetic capital and labor, this study aims to fill this research gap. The study uses a nationally representative survey (N = 1600) fielded in Finland and multinomial regression to determine whether subjective experiences of appearance-related perks and penalties are gendered, dependent on the field of work or daily work on appearances. Our main finding is that while both men and women experience looks-based perks and penalties, men are more likely to have experienced appearance having a say in salary negotiations. Our results shed light on the gendered logics of aesthetic capital and labor, and question economic understandings of beauty work as a pathway to labor market success for women

Objectives: Remission is the ultimate purpose of treatment in rheumatoid arthritis (RA). However, even when the most stringent composite scores are used, structural damages can occur; hence, ultrasonography (US) appears to be the best way to assess real remission. This study aimed to investigate the validity of different RA remission scores using US as a reference. Methods: An analytic diagnostic study, of 30 RA patients in remission (according to the Disease Activity Score in 28 Joints [DAS28]) and a control group with active RA, was conducted between January and October 2018 at Mongi Slim Hospital in Tunis, Tunisia. Among them, patients in remission were identified according to their Simple Disease Activity Index (SDAI), Clinical Disease Activity Index (CDAI) and the Boolean American College of Rheumatology/European League against Rheumatism activity index (ACR/EULAR) remission scores. The validity of each activity score for remission was calculated by considering the absence of power Doppler (PD) signals as a gold standard. Results: All patients were in remission according to the DAS28, with an average score of 2.03 (1.1–2.6). US examination showed PD signals in 57% of patients. A total of 26 patients were in remission according to the CDAI; a Doppler signal was detected in 58% of those cases. SDAI remission was accomplished in 19 patients, with PD activity in 53% of cases. Of the 14 patients in remission according to the Boolean ACR/EULAR criteria, synovial hyper-vascularisation was found in 64%. Considering true remission as the absence of PD signals, the most sensitive and specific score was the DAS28 (93% and 68%, respectively). Conclusion: Considering remission in RA as the absence of vascularised synovitis, the DAS28 is the most sensitive and most specific score.Keywords: Rheumatoid Arthritis; Ultrasonography; Doppler; Reproducibility of Results; Tunisia.

Objectives: This study aimed to determine the association between Helicobacter pylori infection and variceal bleeding as well as rebleeding in cases of cirrhosis with portal hypertension. Methods: This prospective cohort study included patients with bleeding oesophageal varices and was conducted at the Department of Surgery, Jawaharlal Institute of Postgraduate Medical Education and Research, Pondicherry, India, from August 2016 to July 2018. Results: A total of 190 patients were assessed for eligibility, of which 159 patients were included in this study. Among the 159 patients, 124 (78.0%) had alcohol-related liver disease and eight had hepatitis B virus-related liver disease. Seven patients with varices had bled neither at presentation nor during the follow-up period. A total of 78 (49.1%) patients were H. pylori infected. The primary outcome, which was correlation between prevalence of H. pylori and the incidence of bleeding/rebleeding from varices as well as encephalopathy found that patients with oesophageal varices (adjusted risk [AR] = 0.714) and H. pylori infection (AR = 0.682) had a lower risk of variceal rebleeding. Among H. pylori-negative patients, pepsinogen I was higher in patients with rebleeding (30.7 versus 14.4 ng/mL; P <0.001). The secondary outcome, which was correlation of the site of bleeding with H. pylori infection and the association of the ratio of pepsinogen I/II with bleeding showed that among H. pylori-positive patients, the ratio of pepsinogen I/II was higher in patients with rebleeding (2.9 versus 1.3 ng/mL; P = 0.023). Conclusion: H. pylori infection was associated with a lower risk of rebleeding in cases of cirrhosis with portal hypertension. Irrespective of the status of the H. pylori infection, rebleeding was associated with increased levels of gastric acid output, as demonstrated by the level of pepsinogen.Keywords: Pepsinogen; Hepatic Encephalopathy; Gastric Acid; Helicobacter Pylori; India.

Perception of the Ways of Elimination and Prevention of Bullying by Future Secondary School Teachers
Authors: Pasiar Ladislav
Published: September 2021

Are future secondary school teachers able to identify the possibilities for preventing and reducing negative consequences of bullying and cyberbullying using digital technologies? We verified this question through a case study method. Teachers play a very important role in detection, elimination, as well as prevention. It is therefore necessary to educate them and constantly remind them of the seriousness of these problems. In our research, we tried not only to identify the opinions of respondents, future secondary school teachers, but also to emphasize these problems. The existence of ICT have "facilitated" the spread of violent content and thus encouraged its wider expansion. In our research, respondents stated several serious and important ideas. The number of identified cases of bullying and cyberbullying in their vicinity was increasing. There was non-significant number of opinions about non-existence, or ignorance of any kind of bullying near respondents. Despite identifying the contribution of ICT tools to the increase in bullying and cyberbullying, respondents did not mention these tools as possible preventive tools. We can conclude that, although the most respondents are able to identify these issues. The mentioned ways for preventing and eliminating negative consequences were only general and did not exceed basic knowledge about this growing phenomenon.
The Prevalence and Associated Factors of Elderly Abuse: A Cross-Sectional Study
Authors: SEZER Önder , ATAŞ Ceyda Akbaş , DAĞDEVİREN Nezih
Published: September 2021

Objective: The prevalence of elderly abuse varies between 2.2% and 30.1% in European countries. There is a limited number of studies that have investigated elderly abuse in Turkey. The aim of this study is to detect the prevalence and risk factors of elder abuse, identify the factors that can affect elderly abuse, and assess the possible measures to prevent this problem.

Methods: We stratified the districts enrolled in family health centers to ensure that participants were from diverse social, cultural, and economic backgrounds of Edirne and formed a representative sample of 211 people. In addition to sociodemographic characteristics, our survey consisted of the Hwalek-Sengstock Elder Abuse Screening Test, the Geriatric Depression Scale-short form, the Standardised Mini-Mental State Examination, the Barthel Index for activities of daily living, and the Lawton-Brody instrumental activities of daily living scale.

Results: The prevalence of elderly abuse was determined as 9.9%, and high abuse risk was 15.2%. We found that abuse risk was higher among older people who had no social security, lived alone, were abused physically or emotionally before, reported having bad family relations, and had fewer rooms at home which leads to a lack of privacy. Furthermore, we found significant relationships between abuse risk and the depression score.

Conclusion: Elderly abuse is a risk for every person regardless of gender, education level, and economic status. As an invisible problem for societies, elderly abuse brings a great burden by leading to the loss of physical, mental, and psychological health. Preventive measures should be the primary goal. All results suggest that governments, non-governmental organizations, and health care providers should combat this problem by increasing patient literacy and ensuring lifestyle changes.
Apuntes sobre la autoridad de la res iudicata en la jurisprudencia del Tribunal de Justicia de la Unión Europea
Authors: Sarrión Esteve Joaquín
Published: September 2021

El principio de seguridad jurídica tiene, como una de sus manifestaciones características, dentro del Estado de Derecho, la fuerza de cosa juzgada (res iudicata) que se atribuye a las sentencias o resoluciones judiciales equivalentes firmes, y que implica tanto su impugnabilidad como su potencial influencia en litigios posteriores que guarden una conexión con el asunto ya resuelto en firme. Sin embargo, es posible que estas decisiones judiciales firmes de jueces nacionales, por diversas causas (error, omisión, interpretación manifiestamente contraria, etc.) vulneren el Derecho de la Unión Europea y, por tanto, afecten tanto a su primacía como a su efectividad en sus relaciones con los ordenamientos jurídicos nacionales. El Tribunal de Justicia ha tenido oportunidad de enfrentarse al dilema de ponderar el principio de fuerza de cosa juzgada con las primacía y efectividad del Derecho de la Unión en diversas sentencias. Este trabajo tiene como objetivo realizar una aproximación y revisar la jurisprudencia más importante al respecto hasta la actualidad.

The EU’s cybersecurity: a strategic narrative of a cyber power or a confusing policy for a local common market?
Authors: Kasper Agnes , Vernygora Vlad
Published: September 2021

In the last decade, cybersecurity has swiftly turned into a strategic issue and became an important horizontal policy area in the EU, which is treated in this article as one of the four contemporary political empires. These days, the policy arguably encompasses both internal and external aspects, often making it difficult to assess the level of its actual effectiveness as well as outreach. Initially, the EU’s introverted vision on the issue drove the policy to focus on cyber resilience and strategic autonomy. Evidently, the EU’s strategic narrative that could assist it in leading the process of creating an open, free, stable and secure cyberspace in the digital decade, in the context of international security, is emerging. Thus, this contribution is to test the argument that the EU, utilizing an imperial paradigm (consciously or not), is gradually becoming a global steering power in cybersecurity. In this article, firstly, we identify and examine the process of formation of the EU’s narratives about (its) cyber power. Secondly, we establish a discussion framework to highlight the methodological relevance of the imperial paradigm, cyber power Europe and Strategic Narrative Theory for a multidisciplinary debate on global geo-strategic redesign, in which the EU takes part. Thirdly, we look into bilateral and multilateral forums and processes that deal with cybersecurity and in which the EU participates, in order to understand more specifically how the EU is projecting its cyber-power narratives internationally and how cybersecurity-associated challenges impact current dynamics in other policy domains in the field of international relations.

Crecimiento, acumulación y distribución de materia seca en dos variedades de amaranto (Amaranthus hypochondriacus y A. cruentus) bajo fertigación
Authors: Torres Aquino Margarita
Published: September 2021

El cultivo de amaranto se adapta a condiciones agroclimáticas de regiones áridas y semiáridas. Su rendimiento de grano puede incrementarse con fertirriego, pero es necesario generar más información sobre parámetros de crecimiento y rendimiento del cultivo bajo este sistema. El objetivo fue caracterizar el crecimiento, acumulación y distribución de materia seca de dos variedades de amaranto (Frondosa y Dorada) bajo fertigación. La fase de campo se realizó en Salinas, San Luis Potosí, con una densidad de 25 plantas por m2. Se aplicó fertilizante organomineral al suelo y nutrición química en el agua de riego, cuya lámina total fue 321 mm. Frondosa, respecto a la Dorada, llegó más rápido a madurez y mostró valores mayores en: número de hojas; longitud y biomasa seca de panoja; e índice de cosecha (grano/biomasa total). El requerimiento térmico total fue de 910.7 °C y 968.6 ºC para Frondosa y Dorada, respectivamente. Frondosa tuvo mayor eficiencia en el uso del agua (EUA) (7.1 kg mm-1) en grano (2.3 t ha-1), pero la EUA para biomasa fresca (69.6 t ha-1) fue mayor en Dorada (216.6 kg mm-1). Las condiciones ambientales del Altiplano Potosino son favorables para producir Amaranto con alto rendimiento de grano o forraje con fertigación.

Do mito ao rito: novas-velhas categorias para a compreensão da arte moderna
Authors:   Universidade de São Paulo, Stigger Veronica
Published: September 2021

O objetivo desta comunicação é apresentar um resumo de minhas pesquisas sobre a retomada e a renovação das relações entre arte, mito e rito na modernidade. A hipótese central é de que o mito e o rito podem ser entendidos como princípios formais de certa arte das primeiras décadas do século XX – e que, portanto, podem servir também como princípios intelectivos para a crítica desta arte. Para tal, examina-se o que se denomina “dimensão mítica” nas obras de Piet Mondrian e o que se nomeia “dimensão ritual” na Merzbau de Kurt Schwitters.

O eu na auto-ornamentação
Authors: Strathern Marilyn
Published: September 2021

Este texto é uma tradução ao português do texto de Marilyn Strathern (1979), "The Self in Self-Decoration", que versa sobre as performances decorativas do ritual moka entre os Hagen. A autora estabelece uma rede de relações entre a apresentação do eu entre os Hagen e as performances por eles orquestradas atráves de suas enriquecidas ornamentações, com percepções análogas a teorias do corpo e da pessoa que poderiam ser ficcionalmente ensaiadas em culturas que não operam com conceito definido de pessoa. A análise é uma prévia da capacidade analítica da autora em relacionar situações e contextos originalmente pensados como divorciados para fazer evocar sentidos submersos nas ações e condutas culturais, com sua arguta interpretação acerca das concepções ocidentais de estética e do ato do embelezamento de forma confluente às suas menções aos costumes Hagen da auto-decoração. Strathern aponta para uma distinção ontológica entre estes dois contextos que nos permitiria compreender de forma mais esclarecida as críticas apresentadas ao longo de sua obra Gênero da Dádiva (1988), momento posterior de aprofundamento de sua análise sobre a natureza das relações sociais entre os Hagen.
Archaeoparasitology — a new source of reconstruction of migrations of ancient populations: opportunities, results, and prospects
Authors: Slepchenko S.M.
Published: September 2021

The resilience of intestinal parasite ova to harsh environmental conditions and possibility of identification of many of them down to genus/species with the aid of conventional visual light microscopy make parasites an im-portant source of information on different aspects of life of ancient populations. Of special interest is the study of the phenomenon of parasitoidism aimed at reconstruction of ancient human migrations. Ectoparasites (the head louse) and a range of intestinal parasites of such groups as the helminths, tapeworms, and trematodes can be used as a marker of contacts and/or migration of people. Finding helminth ova in ancient samples collected in territories outside the endemic pockets can be direct evidence of contacts and/or migrations of the ancient popu-lation. An example of reconstruction of such migrations is given by, for instance, finding ova of the ascarids and whipworm on the territories of the Far North, mountainous Altai, deserts of the Central Asia etc. A remarkable example of migrations, according to the archaeoparasitology data, is the use of the helminths as a marker of an-cient human migrations, with the example of population of the American continent. It is noteworthy that almost a century old archaeoparasitology data find confirmation in the results of modern paleogenetic studies. In the recent decades, there have been review publications concerned with the finds of ova of various parasitic organisms in archaeological sites, many of which consolidated archaeoparasitology materials dealing with specific intestinal parasites, the impact of the parasites on the human evolution and their (viz., parasites and human) coevolution, and spread of the parasitic diseases as a result of climate changes both in ancient and modern times. All the works, without exception, emphasize the importance of archaeoparasitology data for the deeper understanding of these processes. However, although the first works on the reconstruction of migrations from parasitological data were published back in the beginning of the last century, the research works substantiating this approach and demonstrating its viability appeared only early in this century and elucidated biological pre-requisites for the re-construction of migrations. Therefore, new broad consolidation of the materials on the reconstruction of migrations from the data of archaeoparasitology is motivated not only by the need of reconsideration of already existing and new data, but also by the need of examination and verification of the archaeoparasitology facts in the context of the genetic data, archaeology, anthropology etc.
The origins of the population of Western Siberia in the Early Iron Age according to odontological data
Authors: Sleptsova A.V.
Published: September 2021

The results of the study of the dental anthropology complexes of the population of the Sargatka, Gorokhovo and Kashino cultures of the Early Iron Age in Western Siberia are presented. The source base of the study is 490 individuals from burials located in the Tobol, Ishim, Irtysh River regions, as well as on the territory of the Baraba forest-steppe zone. The aim of this study is to reconstruct the origin and processes of the formation of the anthropological composition of the population of the Sargatka, Gorokhovo and Kashino cultures on the basis of new dental anthropological data. Trigonometrically transformed dental trait frequencies were subjected to the principal component analysis. Be-sides Sargatka, Gorokhovo and Kashino cultures samples, 17 Bronze Age and 27 Early Iron Age dental samples from different region of Eurasia were used for statistical comparison. The results of the statistical comparison may possible to make a several conclusions. The anthropological composition of the Gorokhov population and Sargat groups from the Tobol, Ishim and Irtysh River regions was significantly influenced by diachronic contacts with the descendants of the Andronovo tribes of the Southern Urals, and synchronous relation with the Savromats and Sarmatians of the Southern Urals. The population of the Sargatka culture and the Gorokhovo groups, simultane-ously living on the territory of the Tobol River region in the 5th–3rd centuries BC significantly different from each other. However, the subsequent close population relation between the Sargatka and Gorokhovo groups and their contacts with the Sarmatians contributed to the convergence of their anthropological composition. In the formation of the anthropological composition of the Sargatka population of Baraba forest-steppe zone the main role belongs to the local Late Bronze groups — the Fedorovo Bronze Age population of Western Siberia and their descen-dants, people of the Irmen culture. The most specific is the anthropological composition of the Kashino popula-tion. The specificity of the small group of the Abatsky 3 burial of Kashino culture from the Ishim River region lies in the sharp predominance of the features of the “eastern” dental non-metric complex, which distinguishes this popu-lation from the groups of the Bronze Age and the Early Iron Age of Western Siberia and adjacent territories.
The Khanty of the Yugan River in the Demyanka River basin: formation of local identity
Authors: Adaev V.N.
Published: September 2021

The study is focused on the deep taiga territory located in the upper and middle reaches of the Demyanka River — Uvatsky district of Tyumen Oblast (Western Siberia, Russia). A particular case of the development of local identity in a small community of taiga inhabitants — the Khanty reindeer herders from the Bolshoi Yugan River, who migrated in the first half of the 20th century to the basin of the neighbouring Demyanka River — is presented. This study aims to examine in detail the mechanism of formation of local identity and to trace how a new territorial identity determines development of specific ethnic local community. The paper is largely based on field ethnographic materials collected in 2000–2020, as well as information from archival documents. The study builds upon a system analysis where the formation of a new local community is viewed through the prism of its changing external contacts and socio-cultural boundaries. There were identified the broken links with the historical homeland and new bonds that rooted the people into the new territory. The corresponding role of administrative transforma-tions, socio-economic relations, marriage contacts, and religious beliefs has been established. The main markers of the local identity formed by the 1990s are territorial rooting, a sense of belonging to the region, a new legal status and consolidation of the considered Khanty community. Presently, the descendants of the Bolshoy Yugan Khantys living in the Demyanka River basin are undoubtedly a separate group within the Eastern Khantys with established local identity. Their territorial belonging includes, at the regional level, self-identification as inhabitants of the Uvatsky District, and at the local level, an upheld notion of the Demyanka Region as their homeland. The long isolated exis-tence of the new Khanty community has already led to the emergence of some cultural characteristics that noticea-bly distinguish these Khanty people from their kin who live in the Bolshoi Yugan River basin.
The veneration of “land-water” in the tradition of the northern Khakas — Kyzyls (late 19th — mid-20th century)
Authors: Burnakov V.A.
Published: September 2021

The paper discusses current scientific issues related to the study of the traditional worldview and ritualism of the Khakas people. The work is focused on the analysis of the traditional festival of veneration of “land-water” by the Kyzyls — an ethnic group of the Khakas living in the northern part of Khakassia and in the south of Kras-noyarsk Krai. The characteristic of the ritual complex associated with the worship of the host-spirits is presented: the land spirits (mountains) — tag taig, and the water spirits (springs, lakes, rivers) — sug taiyg. The main sources of the research are unpublished field ethnographic materials. Archival ethnographic information related to this topic, collected in the 1970s by M.S. Usmanova and other researchers from the Tomsk State University, are introduced in the scientific discourse. In the process of studying the indicated problem, it was found that in the culture of the Khakas, including the Kyzyl people, an important place was given to the worship of their native land — sher-sug taiyg. In the religious-mythological consciousness, its specific personification was the spirit-masters of the mountains — tag eezi, and the water spirits — sug eezi. This worldview was due to the natural landscape of the territory in which they live. It features a mountainous terrain with a range of diverse water bodies — the streams, rivers, lakes, etc. The daily domestic life and economic activities of the ethnic community in question were directly related to them. It is argued that in the worldview of the people, connection between the human and nature goes beyond the framework of rational interaction. They were convinced of the close mystical interrelation of natural objects with the life and well-being of people. One of the common ways to maintain a steady balanced relationship between them was the rituals of sacrifice and celebration of these supernatural beings. It was found that in the cult practice of the Kyzyls, the sher-sug taiyg included two or even three specialized rites — tag / kol / sug taiyg, which were closely interconnected with each other and formed a single ritual complex. This sacralized event was held on a regular basis. It had a collective nature with a strictly defined structure, incorporating the leader and other immediate participants, as well as the victim themselves.
Transformation of traditional reindeer herding technologies and pasturing practices 206on the Kola Peninsula in the 20th— early 21st century
Authors: Perevalova E.V.
Published: September 2021

The purpose of the article is to give an accent presentation of the transformation of technologies and tech-niques of reindeer grazing and value attitudes of the Kola reindeer herders in the 20th — early 21st century from an ethno-cultural perspective. The paper is based on the materials of the 2018 expedition to the Kola Peninsula. On the basis of using a system-analytical approach, the paper is structured as a narrative discourse, where the “floor” is given to the Kola reindeer herders themselves. As the studies show, the changes in the Kola reindeer husbandry brought about by the merger of the nomadic Samoyed-Izhem Culture, introduced to the Kola peninsula in the late 19th — early 20th century, with the semi-nomadic “cabin” Saami herding style, as well as by the Soviet period collective and state farm transformation of the traditional reindeer husbandry and the unfolding “snowmo-bile revolution” (the use of the reindeer sled has been reduced to one month in a year), have led not only to the loss of numerous traditional reindeer herding technologies, pasturing practices and herd control, but also to sig-nificant changes in the population composition, structure, and organization of the behavioral characteristics of the herds. Today, the Komi-Izhem reindeer husbandry is dominant in the Kola region. However, despite the major changes, the Kola herders are still quite flexible in using, depending on the circumstances, the advantages of both the Izhem and the Lapp reindeer husbandry systems. The return to the semi-free herds ranging practices and transition to rotational organization of reindeer herd tending in the post-Soviet period stimulated the economic revival of the herding industry and added more comfort to the reindeer herders' lifestyle, although the reindeer herding is not considered a prestigious occupation among young people. Rethinking the older generation's life experiences, together with the more critical perception of today's realities, is an indication of changes within the system of ethnic values, which formerly, in a sense, supported both the individual and collective identities of the Saami and Komi-Izhem ethnies. The transformation processes have had a particularly profound impact on the traditional Saami reindeer culture, almost destroying it, which causes painful memories and reactions of its last bearers. Displacement of the Lapp component is carried forward in the choice of preferred deer breeds and dis-appearance of the Saami language and Saami toponymy from the reindeer herding context.

The paper describes research principles and preliminary results of collaborative interdisciplinary research project aimed at the study of everyday cultural landscapes on the periphery of the Yekaterinburg and Tyumen urban agglomerations. The research design of the project implies a paradigm shift from expert reading of the landscapes to communicative learning of the environment, from the perception of the territories in question as resource reservoirs to their exploration as a domain of affordances providing opportunities for endogenous eco-nomic development. In 2020, an expedition worked in the villages of Tobolsk Zabolotye, in the cities of Irbit and Polevskoy of Sverdlovsk Oblast, and in the village of Belozerskoye of Kurgan Oblast. The cases and places deemed perspective in view of the application of the research method were characterized. This paper mainly pro-vides an overview of the methodological principles that underpin our ongoing study, which should be considered only as an outline of the preliminary results of the first year of field work. The main source of the theoretical inspi-ration for the project design was the idea of affordances, coined by the American psychologist James J. Gibson, who studied the problems of perception. The main methodological objective of the project is to apply the theory of affordances to the field study of strategies for everyday landscape choice. In the 2020 field season, the design of the project, envisaging comparative perspective and increased mobility of researchers, was significantly influ-enced by the method of traveling interview. While working in Tobolsk Zabolotye, we followed everyday patterns of mobility, conducting interviews along the way, discussing with the respondents the hierarchy of places and territo-ries, criteria for identifying vernacular regions, capacity of communication channels, modes of the mobility and its limitations. Concurrently, we were gaining the experience of non-discursive, embodied in materiality and corpore-ality, movement and recording local narratives of identity.

This paper presents the results of the study of the ceramics collection from two periods — Eneolithic and Medie-val, assembled during the fieldwork at the ancient settlement of Ust-Vasyegan 1 in the Northern Priobye (Western Sibe-ria). The Eneolithic ware is represented by fragments of 30 vessels decorated with alveolate, rhombic, nail-imprints, and corner patterns. There are fragments of a boat-shaped vessel and vessels with handles. The complex has analogies in the materials of the settlement of Gorny Samotnel-1 and is dated to the end of the 4th–3rd centuries BC. The Medieval ceramics are represented by 296 vessels. On the basis of typological analysis, two groups of vessels have been identi-fied: group 1 ware with sparing ornamentation comprising 1–4 lines of the ornament; and group 2 ware with an orna-ment comprising 5–8 and more lines. A characteristic feature of the group 2 vessels is the use of a cord and various shaped stamps. In the cultural layer of the settlement, ceramics of both groups was deposited side by side, which sug-gests their contemporaneity. In order to determine the degree of similarity/difference of the derived groups of vessels, a technical-technological analysis was carried out on 20 items. It appeared that potters who manufactured the group 1 vessels routinely used blend compositions of grus and grus with wool. Organic mortars were rarely used. The smoo-thing of the vessels was performed mainly with a wood splinter, knife, or spatula. The craftsmen who manufactured the vessels of group 2 used medium to heavily oversanded clays along with slightly oversanded material. While making the molding compositions, a blend of grus and organic mortar was used more often. Wool was rarely utilised. The vessels were smoothed with soft materials and a knife or spatula, the outer surfaces were subjected to hand tamping. The noted differences suggest, that in the Middle Ages two groups of potters, who had distinctive pottery-making skills, were living at the settlement. Vessels of the group 1 have similarities with materials of the “Bichevnik” type from the Pechersky Trans-Urals, whereas vessels of the group 2 in the materials of the Yarsalinsky, Ust’-Poluisky, and Yudinsky Cultures of the Iron Age and Early Middle Ages of the Middle and Lower Priobye and Lower Tobol River region. Obtained radiocarbon dates and some artefacts (a bronze signet ring and an iron dagger), which have analogies in the Middle Trans-Urals, define the time span of the activity for the ancient settlement of Ust-Vasyegan 1 within the 7th–13th centuries.
A Review Paper on ELT Articles Conducted on EFL Teachers’ Perceptions, Practices and Challenges towards Communicative Language Teaching

This review paper aimed at reviewing English language teaching articles on EFL teachers’ perceptions, practices and challenges towards communicative language teaching. In this review, two ELT articles, which have been conducted on teachers’ perceptions, practices and challenges towards communicative language teaching in EFL classes, were reviewed in detail. While reviewing the articles, the researcher adapted Rideley’s (2008) checklist to evaluate elements of article. Thus, articles were reviewed by focusing on the title, abstract, introduction, research questions, objectives, research design, participants, sample and sampling techniques, data collecting instruments, methods of data analyses, findings and references based on the checklist provided above. The review revealed that the articles had clear objectives, researchable questions, appropriate methods and inevitable conclusions. They tried to answer the questions which were raised in each article, and the objectives went along with the overall research findings. The review, on the other hand, revealed that the participants in the articles were not representative so as to conclude and generalize the overall population by taking only few participants which were selected even by using non probability sampling.

Efficient quality evaluation provides support for the timely and good maintenance of the lane line marking. This paper searches and optimizes the back propagation(BP) network model which referred to the analytic hierarchy process(AHP) model structure, as well as the number of nodes in the middle layer network. Based on this, a comprehensive evaluation method of multi-dimensional lane line quality such as shape, color and contrast is established. The experimental results show that the parameters of the model are more simplified, and the scoring and classification results of lane lines are more accurate.
Comparison of generic and proprietary aquatic herbicides for control of invasive vegetation; part 3 : submersed plants
Authors: Mudge Christopher , Getsinger Kurt
Published: September 2021

Herbicide selection is key to efficiently managing nuisance vegetation in our nation’s waterways. After selecting the active ingredient, there still remains multiple proprietary and generic products to choose from. Recent small-scale research has been conducted to compare the efficacy of these herbicides against floating and emergent species. Therefore, a series of mesocosm and growth chamber trials were conducted to evaluate subsurface applications of the following herbicides against submersed plants: diquat versus coontail (Ceratophyllum demersum L.), hydrilla (Hydrilla verticillata L.f. Royle), southern naiad (Najas guadalupensis (Sprengel) Magnus), and Eurasian watermilfoil (Myriophyllum spicatum L.); flumioxazin versus coontail, hydrilla, and Eurasian watermilfoil; and triclopyr against Eurasian watermilfoil. All active ingredients were applied at concentrations commonly used to manage these species in public waters. Visually, all herbicides within a particular active ingredient performed similarly with regard to the onset and severity of injury symptoms throughout the trials. All trials, except diquat versus Eurasian watermilfoil, resulted in no differences in efficacy among the 14 proprietary and generic herbicides tested, and all herbicides provided 43%–100% control, regardless of active ingredient and trial. Under mesocosm and growth chamber conditions, the majority of the generic and proprietary herbicides evaluated against submersed plants provided similar control.
A Norwegian Oil Company Could Play a Key Role in Brazil’s Gas Transformation
Authors: Rassenfoss Stephen
Published: September 2021

Equinor could play a critical role in Brazil’s drive to boost its economy by opening up its gas markets. The Norwegian oil company operates two huge deepwater blocks with enough gas to lower prices in the country where big users pay some of the highest prices in the world.

The development plan for one of those blocks, BM-C-33 in the Campos Basin, would deliver an average of 14 million m3/d of gas—about 15% of the country’s gas demand on a high-consumption day, which is about 92 million m3/d, based on data from Rystad.

A second project in the heart of the presalt, Bacalhau, could become a model for how an international oil company can market gas successfully in the country’s richest oil play, the Santos Basin presalt.

The gas potential in that play is also huge; the gas/oil ratio is high compared with other Brazilian fields but has largely been untapped.

So far, Equinor and its partners in the projects have not committed to developing gas on either lease, but Equinor appears to be seriously considering doing so. The big question it needs to answer is what the gas market there will look like in a year or so.

Brazil has set out to promote domestic gas supplies by ending Petrobras’ virtual monopoly in the pipeline business in favor of a less-regulated, competitive gas market.

Equinor avoided gas sales at Bacalhau with an $8 billion Phase 1 plan that will use the popular practice of reinjecting produced gas. Gas reinjection maintains reservoir pressure and allows the development to comply with Brazil’s ban on routine flaring. Brazil’s energy regulator, ANP, said that when Equinor develops a plan for its second phase of development, the company needs to con-sider gas production.

The role of gas market pioneer is the latest technical challenge taken on by Equinor in Brazil. Previously, it became the operator of an offshore heavy-oil field—Perigrino—and an aging giant—Roncador—both in the Campos Basin.

While the Norwegian company has not promised to take on that role, it has a huge incentive to do so as the operator of Block BM-C-33, where most of the reserves are in the form of gas. The resource is estimated at 3 Tcf of gas and 700 million bbl of condensate, according to Offshore Technology.

Equinor and its partners Repsol and Petrobras have developed a plan that would move the liquids by tanker from the platform, which is in water as deep as 2900 m, and build a pipeline about 200 km from there to shore.

When asked about the status of the project, Geir Tungesvik, senior vice president for project development at Equinor, said the company is working to “improve the business case.”

A Potential Case Study Tungesvik’s bland description fails to reflect the risks and uncertainties faced by those trying to put together offshore gas marketing plans in Brazil.

If Equinor and its partners go forward with their plan to monetize that massive gas reserve, the result is likely to be a case study for those who follow. It could either be a model for successful development or a cautionary tale.
