Willingness to participate in prevention programmes. Key factors based on the example of the BGW back school Objectives: Employees in nursing professions run a high risk of back-related disorders. The German Social Accident Insurance Institution for the health and welfare services (Berufsgenossenschaft für Gesundheitsdienst und Wohlfahrtspflege – BGW) has developed a multi-stage programme of secondary individual prevention (SIP) with a back clinic, back school and refresher course in order to counteract the cause of occupational diseases of the lumbar spine. The aim of the study was to identify what factors influence the willingness to participate in these programmes. Methods: The study is based on data from 1011 participants who attended the back clinic at the Hamburg regional office of the BGW between 2012 and 2019. They were collected by means of a standardised questionnaire and an orthopaedic examination. The evaluation was based on a t-test for independent samples and the Levene test, which was used to verify the homogeneity of variance. Results: It was found that increasing age and a higher number of years in the job results in a significant increase of willingness to participate. At the same time, a higher level of BMI and the number of non-back disorders both have a significant inhibitory impact on participation. Conclusions: The use of preventive programmes will increase in terms of relevance. General state of health is a key factor in whether or not programmes are used by potential participants. Finally, the overall objective should be to develop solutions that encourage the willingness to participate even in the early stages of working life. Keywords: lumbar spine – prevention – back clinic – back school

The COVID-19 Working Time Ordinance: Implications for occupational safety and health and insights from an employer survey Aims: In this article, we discuss the COVID-19 Working Time Ordinance against the background of selected recent scientific evidence in the field of occupational safety and health. The article describes the potential implications, especially with regard to long working hours and the shortening of minimum rest periods as well as the deregulation of work on Sundays and holidays. In addition, we present employer survey data on the actual level of awareness and use of the COVID-19 Working Hours Ordinance. Method: Current literature reviews and meta-analyses, large-scale studies/consensus papers and recommendations on the management of long working hours, shortened rest periods (quick returns) and work on Sundays or public holidays are used for the scientific evaluation. The analyses of the level of awareness and use of the COVID-19 Working Time Ordinance are based on the second wave of the “Enterprises in the COVID-19 Crisis” survey. Results: The deviations from the Working Hours Act in the COVID-19 Working Time Ordinance are associated with a high risk of negative effects on the safety and health of employees. Overall, only a small proportion of the companies in the survey reported that they used the deviations in the Ordinance, mostly in the retail sector and in micro-enterprises. Conclusion: The derogations from the Working Hours Act appear to be counterproductive from an occupational safety and health perspective, especially in the context of coping with the high work intensity during the SARS-CoV-2 epidemic. Structural problems, such as the shortage of skilled workers, should be addressed more closely in the future in order to enable healthy and sustainable working time models, particularly in times of extreme workloads.

The growing anthropogenic load on fluvial hydrosystems is now becoming a real threat. The aim of the research was to assess the state of vegetation and soil in the territory of water protection river zones in the delta part of the Volga river in high ecological risk areas. In order to achieve it, standard methods of biotesting and bioindication were used in the territories of two water protection zones. The results of the research showed that the soils of Sokolovsky Oil Pits are the most toxic of all: the germination capacity of the test object (watercress) is 6 times lower than that at other monitoring sites. In summer and autumn, all monitored sites demonstrated the maximum rates of occurrence and abundance of typical representatives of the local flora these are camel thorn (Alhagi pseudalhagi) and greater burdock (Arctium lappa). In 2018–2020, indicators of abundance of all thirteen-plant species registered in the oil-contaminated area (Sokolovsky Oil Pits) have a positive trend, the area gets more and more overgrown.
Anthropogenic and Natural Dynamics of Landscape Ecosystems of the Slovechansko-Ovruchsky Ridge (Ukraine)
Authors: Harbar Oleksandr , Khomiak Іvan , Kotsiuba Іryna , Demchuk Nataliia , Onyshchuk Іryna
Published: February 2022

The need for landscape management cannot be satisfied by static data alone. Landscape ecosystems are complex dynamic objects and the successful protection or operation of such areas depends on the quality of monitoring their dynamics and the forecasts built on its basis. Forecasting accuracy also depends on the quality of the modelling and this is why it is necessary to highlight the most universal and key characteristics of ecosystems. The Slovechansko-Ovruchsky ridge, which has a phenomenally high variety of landscapes, is well suited as an object for testing approaches to modelling. The authors singled out 11 territorial parts of the Slovechansko-Ovruchsky ridge at the level of landscapes and tracts. The differentiation of these landscapes was assessed using the synphytoindication method to determine the value of natural and anthropogenic dynamics. This made it possible to build prognostic algorithms for ecosystem changes using geobotanical data and produce prospects to create the best suitable landscape protection strategy or more effective and safe exploitation of landscapes.
dsDNA quantification using Sybr Green I v2
Authors: JN Kitson James
Published: February 2022

This is a simple protocol that uses Sybr Green 1 and a microplate reader to quantify dsDNA concentrations in unknown samples. This is best suited for situations where a high number of samples need to be quantified (e.g. normalisation of samples before pooling for Illumina sequencing). For smaller sample numbers (e.g. < 50 samples) it will be more efficient to simply use a qubit or nanodrop. You need to pick an appropriate standard concentration range for the type of samples you will be testing. For genomic DNA it is probably better to have a lower concentration range (0-10 ng/μl) whereas for PCR products, standards will probably need to be much more concentrated (0-50 or maybe even 100ng/μl).

The Q5 High- Fidelity 2X Master Mix features a high-fidelity, thermostable DNA polymerase with 3´→ 5´ exonuclease activity, fused to a processivity-enhancing Sso7d domain to support robust DNA amplification. With an error rate ~280-fold lower than that of Taq DNA Polymerase, Q5 High-Fidelity DNA Polymerase is ideal for cloning and can be used for long or difficult amplicons. The convenient master mix formulation is supplied at a 2X concentration. The mix contains dNTPs, Mg++ and a proprietary broad-use buffer requiring only the addition of primers and DNA template for robust amplification regardless of GC content. When used at the recommended 1X final concentration, the Q5 High-Fidelity Master Mix contains 2 mM Mg++. Q5 High-Fidelity DNA Polymerase is unlike typical, lower fidelity PCR enzymes. To determine the optimal annealing temperatures for a given set of primers, use of the NEB TmCalculator is highly recommended.
Measurement of dissolved black carbon in water via benzenepolycarboxylic acid (BPCA) oxidation and quantification using aqueous, inorganic, high-performance liquid chromatography v1
Authors: Barton Riley , Wagner Sasha
Published: February 2022

Dissolved black carbon (DBC) is the condensed aromatic portion of dissolved organic matter produced from the incomplete combustion of biomass and other thermogenic processes. DBC quantification facilitates the examination of the production, accumulation, cycling, transformation, and effects of biologically recalcitrant condensed aromatic carbon in aquatic environments. Due to the heterogeneous nature of DBC molecules, concentrations are difficult to measure directly. Here, the method for DBC quantification consists of oxidizing condensed aromatic carbon to benzenepolycarboxylic acids (BPCAs), which are used as proxies for the assessment of DBC in the original sample. The concentrations of BPCA oxidation products are quantified using high-performance liquid chromatography. DBC concentrations are determined from the concentration of BPCAs using a previously established conversion factor. Details and full descriptions of the preparative and analytical procedures and techniques of the BPCA method are usually omitted for brevity in published method sections and method-specific papers. With this step-by-step protocol, we aim to clarify the steps of DBC analysis, especially for those adopting or conducting the BPCA method for the first time.
Heritage Spanish Speakers’ Writing Development: Online vs. In-Person Peer-Tutoring Interventions
Authors: Lozano Claire Julia , Carando Agustina
Published: February 2022

This article analyzes the writing development of heritage speakers (hs) of Spanish in an intermediate level composition course at the University of California, Davis. The data comprised 480 essays written by 80 students from two groups: one who received face-to-face peer tutoring before the covid-19 pandemic (Fall 2019), and one who received online tutoring during the pandemic (Fall 2020). These data were analyzed in terms of lexical richness as measured by (a) lexical density, (b) lexical sophistication, and (c) lexical variation in both in-person and online settings. Findings revealed that lexical density and lexical sophistication were similar in both groups. However, the online group had higher levels of lexical variation throughout their essays. We conclude that online tutoring is an effective alternative to face-to-face tutoring, showing no disadvantages in terms of students’ lexical richness and offering a significant advantage with respect to lexical variation. Finally, we offer suggestions for hs tutor training in an online setting.
Multimodal Communication in an Early Childhood Bilingual Education Setting: A Social Semiotic Interaction Analysis
Authors: Escobar Almeciga Wilder Yesid , Brutt-Griffler Janina
Published: February 2022

Bilingual learners often integrate semiotic resources and communicative modes across the languages they speak. Unfortunately, current approaches to researching such a phenomenon assign pragmatic functions to individual discourse moves at best or to isolated utterances at worst. Thus, using a social semiotic multimodal interaction analysis, this study examined actions in interac­tions of a group of six transnational students participating in a second-grade literacy circle at a school in western New York, USA. The purpose of this was to account for the complex reciprocities among their multimodal ways of communicating, their learning climate, and ultimately their learning as mediated and evidenced in their integrated multimodal communicative action. Data included four audio recordings of four literacy circle reading activities that took place during a four-day period. Findings sug­gest that, first, learning results from communication. Second, learning can only be evidenced through communication in interaction. Finally, communication is always multimodal and emergent while, at the same time, culturally governed. This presents direct implications for instruction and learning regarding the social conditions afforded to students to access their full repertoire of semiotic resourc­es and modes to participate and act on their own behalf and in pursuit of their learning.
Neutralization of the Tap/Trill Contrast in the Bilingual Creole-Spanish Community of the Archipelago of San Andres, Colombia
Authors: Restrepo-Ramos Falcon
Published: February 2022

This study examines the segmental duration of non-vibrant rhotics in a language contact scenario in the Western Caribbean, where an English-based Creole co-exists with Spanish: The Archipelago of San Andres, Colombia. The unexplored phenomenon of the neutralization of the tap/trill contrast merits a thorough analysis to examine the effects of language contact in this Creole-Spanish bilingual population. To do this, the segmental duration of 619 non-vibrant, intervocalic taps and trills were compared in three generations of Raizal Spanish (the bilingual Spanish variety) and contrasted with the duration of Continental Spanish (the monolingual variety spoken by Colombian immigrants from Continental Colombia). While there are language-specific differences in rhotic duration between Creole and Spanish, results show that Raizal Spanish has longer durations that differ from the monolingual Spanish variety. A cross-generational examination revealed that the neutralizations of the tap/trill contrast in older bilinguals, as third-generation speakers, are converging toward the monolingual variety, distancing themselves from the older second and first generations. This phenomenon signals a change in progress resulting from diverging variation patterns of duration in tap/trill segments in generations of bilingual Raizales. These findings suggest a changing sociolinguistic panorama in which stable bilingualism is taking place among younger individuals.

Published: February 2022

La literatura relacionada con estudios contrastivos entre lenguas nativas de Colombia y el español es muy escasa. En aras de contribuir al cambio de esta realidad, este estudio ofrece un análisis contrastivo de los pronombres de sujeto, objeto directo e indirecto entre las lenguas wayuunaiki y español. La comparación se enmarca en la lingüística contrastiva y da cuenta de las similitudes y diferencias entre los sistemas gramaticales de ambas lenguas. Los resultados ponen en evidencia algunas semejanzas entre las dos lenguas, como el uso de sujetos nulos y el hecho de que sus pronombres, con algunas excepciones de los de sujeto, no establecen diferencias entre géneros para la primera y la segunda persona, contrario a lo que sucede con la tercera. Por otro lado, también revelan algunas diferencias notables en relación con la posición que estas unidades gramaticales ocupan en la estructura oracional, las marcas utilizadas cuando no se enuncia explícitamente el pronombre de sujeto y la estructura morfológica. Este estudio constituye una primera mirada contrastiva y tiene implicaciones para la enseñanza de lenguas, la traducción, los estudios de contacto de lenguas y de bilingüismo, dada la identificación que hace de posibles interferencias, variaciones y cambios lingüísticos.
Examining Hegemonic and Monoglossic Language Ideologies, Policies, and Practices Within Bilingual Education in Colombia
Authors: Bettney Esther
Published: February 2022

From the lens of coloniality, monoglossic and hegemonic language ideologies and policies exist within public and private bilingual education in Colombia which oppress students’ and teachers’ diverse linguistic identities and languaging practices.This article draws on critical scholarship which recognizes the need to decolonize language education. As such, it includes a review of key literature from the fields of language ideologies, language policy, and classroom languaging practicesto consider alternative approaches to bilingual education from a heteroglossic stance, including translanguaging and critical multilingual language awareness.The literature review suggests that within the Colombian context, hegemonic and monoglossic ideologies and practices are present within international private bilingual schools and through the National Bilingual Program. In addition, anunderlying logic of coloniality exists in both public and private language education as both contexts hold foreign languages, expertise, and relationships as more valuable than their local equivalents. However, recent classroom-based research in Colombia indicates promising new heteroglossic approaches which not only acknowledgethe benefits, but also support diverse linguistic identities and practices.

CONFLICTOLOGY OF TAX LEGAL RELATIONS: THEORETICAL AND METHODOLOGICAL ASPECT
Authors:   University of the State Fiscal Service of Ukraine, Chaika Victoria , Chaika Larysa ,   Research and Educational Centre of Foreign Languages of the National Academy of Sciences of Ukraine
Published: February 2022

Purpose. The objective of the article is to establish the content and meaning of conflicts that arise and cease in the field of tax relations. Methods. The evolution of scientific conflict concepts is due to the interdisciplinary approach: emphasis is placed on the impossibility of separating philosophical, social, psycholinguistic and legal aspects of the conflict. Comprehensive and systematic analysis of the “conflict” category was carried out using an integrative approach. Results. Modern approaches to the conflict as an object of scientific analysis are differentiated into two main groups: 1) the conflict is considered in a narrow field sense; 2) the conflict is studied from interdisciplinary positions. The legal nature and attributive properties of the tax conflict are clarified from the standpoint of the tax law theory. There are five groups of factors that confirm the actual existence of conflicting tax relationships. A special attention was paid to the characteristics of the tax dispute (as one of the stages of the tax conflict) and ways to protect the rights of taxpayers. In particular, the issue of self-protection of taxpayers’ rights as a guarantee of the realization of subjective rights and legitimate interests in tax relations and as a basis for preventing tax conflicts and tax disputes was highlighted. Conclusions. It is proved that the basis of any conflict is a contradiction, which plays a systemic role both for certain types of conflict and for different levels of their research. However, the presence of contradictions forms only the preconditions of possible behaviour, while interpersonal relationships – as a social category – play a crucial role in the choice of an individual strategy in communicative interaction. It was substantiated that the tax dispute is a mechanism to guarantee the realization of subjective rights of stakeholders and the balance of public and private interests in the field of taxation, given the following factors: 1) focus on protection and restoration of violated (disputed) rights, further; 2) focus on resolving the tax conflict that has arisen over the exercise of rights and obligations; 3) focus on ensuring stability of conditions to implement the legal norm and optimization of legal regulation; 4) considering the dispute by the state power authorized body ensures stability of the legal system of a society. It is determined that a tax dispute is a tax conflict of the tax relations subjects, submitted for consideration to the authorized jurisdiction body, concerning their mutual rights and obligations, as well as the conditions of their implementation, and which requires a solution based on a legal assessment of the facts and verification of the legality of the government entity’s actions in relation to the taxpayer.

MITOCHONDRIAL COI GENE BARCODING OF FOUR SPECIES OF GENUS ISCHNURA (ODONATA: COENAGRIONIDAE) FROM INDIA
Authors: G.K. Dhillon G.K. Walia and
Published: February 2022

Taxonomically, identification of complex taxa based on external morphological characters may leads to wrong identification of unknown organism at species level because these characters may also be altered due to geographical and seasonal variations. To overcome this molecular taxonomy has been emerged. In India, out of 9 morphologically described species of genus Ischnura (Odonata: Coenagrionidae), Ischnura senegalensis is the only species, which has been barcoded on the basis of COI gene. During the present study, mitochondrial COI gene has been barcoded for four species of genus Ischnura (Ischnura aurora, Ischnura forcipata, Ischnura rufostigma and Ischnura senegalensis), collected from fresh water bodies from the states of Punjab and Himachal Pradesh (India). Across the final alignment of COI sequences of 352bp, there are 282 conserved sites (80.1%), which represents that COI gene is highly conserved. Conspecific species show <1% divergence range (0% to 0.6%) and interspecific divergence ranges from 7.5% to 15.6%. COI gene sequences of all the species shows 95 – 100% similarity with the sequences of conspecific species deposited in GeneBank. Mitochondrial COI gene based DNA barcoding has been done for Ischnura aurora, Ischnura forcipata and Ischnura rufostigma for the first time from India and for Ischnura forcipata throughout the world.

Micro/sub-microscale fibrillar architectures of extracellular matrix play important roles in regulating cellular behaviors such as attachment, migration, and differentiation. However, the interactions between cells and organized micro/ sub-microscale fibers have not been fully clarified yet. Here, the responses of MC3T3-E1 cells to electrohydrodynamic (EHD) printed scaffolds with microscale and/or sub-microscale fibrillar architectures were investigated to demonstrate their potential for bone tissue regeneration. Fibrillar scaffolds were EHD-fabricated with microscale (20.51 ± 1.70 μm) and/or sub-microscale (0.58 ± 0.51 μm) fibers in a controlled manner. The in vitro results showed that cells exhibited a 1.25-fold increase in initial attached cell number and 1.17-fold increase in vinculin expression on scaffolds with micro/sub-microscale fibers than that on scaffolds with pure microscale fibers. After 14 days of culture, the cells expressed 1.23 folds increase in collagen type I (COL-I) deposition compared with that on scaffolds with pure microscale fibers. These findings indicated that the EHD printed sub-microscale fibrous architectures can facilitate attachment and COL I secretion of MC3T3-E1 cells, which may provide a new insight to the design and fabrication of fibrous scaffolds for bone tissue engineering.

We studied the effect of essential oils and music fragments, as wellas their various combinations on the brain’s electrical activity parameters.We showed the character of their impact on the basicEEG frequency bands, identified localization of sources for specificactivity. It was found that the olfactory and musical influenceof different modalities have unidirectional effect on the bioelectricactivity indices. This EEG response is most likely associated with acommon mechanism for implementing the effects of audio andodorant stimulants. It was found that the response to the combinationsof sensory effects has different intensity. These data permit thesensory effects to be ranked in terms of their activation level, whichmakes it possible to purposefully influence the psycho-emotionalstates. Our findings are the basis for developing further methodsand programs of modifying the athletes’ functional states.

Authors:   Northwestern Polytechnical University, Shaanxi, China, Wu Jinrui , Tian Jianguo
Published: February 2022

As terms that do not have practical meaning but can fully express the speaker’s emotion and attitude, pet phrases are widely used in our daily life. While it is hard for us to realize its important role in communication due to its frequent use. As two distinct languages, pet phrases in Chinese and English have quite diverse origins. Therefore, this article will take several typical characteristics as examples and attempt to analyze the differences between Chinese and English in the use of pet phrases and the main causes of such distinctions from the perspective of sociolinguistics. The purpose of this study is to eliminate misunderstandings caused by the pet phrases between Chinese and English speakers so that both sides will gain some insights into each other’s culture, avoid pragmatic failure and achieve the goal of cross-cultural communication.

Published: February 2022

The Plague written by Camus tells the story of fighting against the plague. The anti-epidemic organizations gathered around the hero, Dr. Rieux struggle against the plague during the closure of Oran. Throughout the story, whether it’s the process from the occurrence of plague to the real confirmation, or the process of the anti-epidemic teams being organized, the indigenous inhabitants of Oran City—the Arabs are all marginalized objects and silent “others”. In addition, the Arab lands are full of French-style life and management methods, and Spanish-style building. These are the revelation of Camus's deep-rooted imperial consciousness.

The methods for the synthesis of lithium iron phosphate LiFePO4 with olivine structure have been developed. New materials based on lithium iron phosphate, including doped with metals, the «LiFePO4 + carbon» composites obtained by pyrolysis of organic compounds have been synthesized. Crystallographic characterization of the synthesized materials was carried out; their electrochemical characteristics of the extraction and intercalation of lithium have been identified. A correlation between the crystallographic and electrochemical characteristics of the materials was found. It was confirmed that an effective way to improve the electrical conductivity of LiFePO4 is to create a carbon shell of the products of pyrolysis of organic compounds on the material’s particles surface. A correlation of electrical conductivity and temperature of synthesis of the material was determined. The sequence of chemical interaction between precursors for the synthesis of LiFePO4 is defined; the mechanism of solid-phase interaction is described.
