Background: Characterization studies of COVID-19 patients with chronic obstructive pulmonary disease (COPD) are limited in size and scope. The aim of the study is to provide a large-scale characterization of COVID-19 patients with COPD.

Methods: We included thirteen databases contributing data from January-June 2020 from North America (US), Europe and Asia. We defined two cohorts of patients with COVID-19 namely a ‘diagnosed’ and ‘hospitalized’ cohort. We followed patients from COVID-19 index date to 30 days or death. We performed descriptive analysis and reported the frequency of characteristics and outcomes among COPD patients with COVID-19.

Results: The study included 934,778 patients in the diagnosed COVID-19 cohort and 177,201 in the hospitalized COVID-19 cohort. Observed COPD prevalence in the diagnosed cohort ranged from 3.8% (95%CI 3.5-4.1%) in French data to 22.7% (95%CI 22.4-23.0) in US data, and from 1.9% (95%CI 1.6-2.2) in South Korean to 44.0% (95%CI 43.1-45.0) in US data, in the hospitalized cohorts. COPD patients in the hospitalized cohort had greater comorbidity than those in the diagnosed cohort, including hypertension, heart disease, diabetes and obesity. Mortality was higher in COPD patients in the hospitalized cohort and ranged from 7.6% (95%CI 6.9-8.4) to 32.2% (95%CI 28.0-36.7) across databases. ARDS, acute renal failure, cardiac arrhythmia and sepsis were the most common outcomes among hospitalized COPD patients.  

Conclusion: COPD patients with COVID-19 have high levels of COVID-19-associated comorbidities and poor COVID-19 outcomes. Further research is required to identify patients with COPD at high risk of worse outcomes.

Published: January 2023

Los artrópodos es uno de los grupos de organismos más diversos. Se estima que representan el 80% de los animales vivos.  Entre ellos se encuentran los insectos (mariposas, mosquitos, escarabajos, etc.), arácnidos (arañas, ácaros y alacranes), quilópodos (ciempiés) y diplópodos (milpiés), clases de organismos de los cuales se alimentan los murciélagos artropodófagos. Estos organismos se caracterizan por tener ciclos de vida cortos con altas tasas reproductivas que les permiten ser abundantes en determinadas estaciones del año, ante cambios ambientales, o en la estructura de la vegetación que les favorece su reproducción; en consecuencia, pueden proliferar al grado de convertirse en plagas que afectan a bosques y cultivos de interés para la economía humana.

Dynamic attitude measurement taken by monocular line scan vision
Authors: Wang Qing , Zhang Guohua
Published: January 2023

Attitude measurements are important parameters for condition monitoring of precision machines. We develop an angle measurement method based on monocular line scan vision to dynamically measure the attitude of shafts. The proposed measurement system, which consists of a single line scan camera, a parallel laser light source, and a triangular mirror, does not require fixation of a sensor on the shaft. The measurement system uses the line scan camera to capture the projection of the shaft. The light source is diffused by a cylindrical lens to yield parallel directional light. Then the parallel directional light is reflected by a fixed-angle mirror and projected onto the projection plane. The captured image can be considered a discrete time sequence. The attitude measurement principle based on linear monocular vision is derived. A double light-spot centroid algorithm is developed to obtain the centroid coordinates of the projection points. The proposed method is investigated by a simulation and experiment. The proposed method can also monitor the vibration of the shaft. The experimental results prove that the proposed method is effective and highly accurate.

High quality 0.3 at.% Pr, 2.5 at.% Yb:BaF2 and 0.6 at.% Pr, 3 at.% Yb:BaF2 single crystals were grown by the temperature gradient technique (TGT). The absorption spectra, fluorescence spectra, fluorescence decay curves and energy transfer process are measured and analyzed at room temperature. By co-doping Yb3+ ions as a sensitizer of Pr3+ ions, the broad near-infrared band emission from 1G4 energy level at 1.3 µm is observed in the Pr3+/Yb3+: BaF2 crystal with low maximum phonon energy for the first time. In addition, the visible fluorescence emission can be detected and the luminescence components are mainly blue-green transition. The emission cross sections of 1G4→3H5 and 3P0→3H4 transitions are calculated to be 0.21 × 10−20 cm2 and 1.12 × 10−20 cm2 with the larger FWHM of 103.8 nm and 4.2 nm in 0.6 at.% Pr, 3 at.% Yb:BaF2 crystal, respectively. The luminescence lifetime of 1G4 and 3P0 energy levels are fitted to be 259.6 µs and 126.1 µs in 0.3 at.% Pr, 2.5 at.% Yb:BaF2 crystal, which is much increased by Yb3+ ions co-doping. The energy transfer efficiency in BaF2 crystal from Yb3+ to Pr3+ ions is calculated to be 60.3% and 70.5%, respectively. All results show that the Pr3+/Yb3+:BaF2 crystal is a promising candidate of laser gain medium for near-IR laser at 1.3 µm and blue laser operation.

Published: January 2023

Background

Mother and newborn skin-to-skin contact (SSC) plays a key role in breastfeeding practices of mothers. In this study, we examined the association between mother and newborn SSC and timely initiation of breastfeeding in sub-Saharan Africa (SSA).

Methods

This cross-sectional study utilized nationally representative data from the Demographic and Health Surveys of 17 countries in SSA from 2015 to 2020. Multilevel binary logistic regression analysis was performed to examine the association between mother and newborn SSC and timely initiation of breastfeeding. The results are presented using adjusted odds ratios (aOR), with 95% confidence interval (CI).

Results

The pooled prevalences of mother and newborn SSC and timely initiation of breastfeeding were 45.68% (95% CI = 34.12–57.23) and 62.89% (95% CI = 55.67–70.11), respectively. Mothers who practiced newborn SSC were more likely to practice timely initiation of breastfeeding compared to those who did not practice SSC [aOR = 1.68, 95% CI = 1.58, 1.78] and this persisted after controlling for all the covariates [aOR = 1.38, 95% CI = 1.29, 1.47]. At the country level, mother and newborn SSC increased the odds of timely initiation of breastfeeding in Angola [aOR = 1.99, 95% CI = 1.44, 2.76], Cameroon [aOR = 1.43, 95% CI = 1.02, 1.99], Ethiopia [aOR = 1.62, 95% CI = 1.16, 2.28], Guinea [aOR = 1.69, 95% CI = 1.10, 2.60], Liberia [aOR = 2.03, 95% CI = 1.33, 3.12], Malawi [aOR = 1.47, 95% CI = 1.02, 2.12], Mali [aOR = 1.42, 95% CI = 1.10, 1.84], Sierra Leone [aOR = 1.87, 95% CI = 1.23, 2.83], South Africa [aOR = 2.59, 95% CI = 1.41, 4.76], Tanzania [aOR = 1.60, 95% CI = 1.27, 2.01], Uganda [aOR = 1.43, 95% CI = 1.02, 1.99], Zambia [aOR = 1.86, 95% CI = 1.50, 2.30], and Zimbabwe [aOR = 1.65, 95% CI = 1.24, 2.21].

Conclusion

The prevalence of SCC was relatively low but timely initiation of breastfeeding was high. Mother and newborn SSC is a strong predictor of timely initiation of breastfeeding in SSA. To enhance timely initiation of breastfeeding after birth, this study recommends that more child and maternal healthcare interventions focused on improving mother and newborn SSC should be implemented.

Published: January 2023

CRISPR-based genome editing technology is revolutionizing prokaryotic research, but it has been rarely studied in bacterial plant pathogens. Here, we have developed a targeted genome editing method with no requirement of donor templates for convenient and efficient gene knockout in Xanthomonas oryzae pv. oryzae (Xoo), one of the most important bacterial pathogens on rice, by employing the heterologous CRISPR/Cas12a from Francisella novicida and NHEJ proteins from Mycobacterium tuberculosis. FnCas12a nuclease generated both small and large DNA deletions at the target sites as well as it enabled multiplex genome editing, gene cluster deletion, and plasmid curing in the Xoo PXO99A strain. Accordingly, a non-TAL effector-free polymutant strain PXO99AD25E, which lacks all 25 xop genes involved in Xoo pathogenesis, has been engineered through iterative genome editing. Whole-genome sequencing analysis indicated that FnCas12a did not have a noticeable off-target effect. In addition, we revealed that these strategies are also suitable for targeted genome editing in another bacterial plant pathogen Pseudomonas syringae pv. tomato (Pst). We believe that our bacterial genome editing method will greatly expand the CRISPR study on microorganisms and advance our understanding of the physiology and pathogenesis of Xoo.
Do (Perceptions of) Electoral Polling Affect Voters' Behavior? Campaigns, Partisan Bias, and Strategic Voting
Authors: Castro Cornejo Rodrigo
Published: January 2023

The manuscript highlights the major role that partisanship plays in moderating voters’ interpretation of polling information and incentives to behave strategically. While prior studies highlight that partisans are less likely to vote strategically as the expressive costs of defection increase, this study sheds light on the conditions in which voters—even partisans—behave strategically and which contribute to an increase in the proportion of voters who change their vote intention during campaigns. Only partisans informed about polls are able to overcome their partisan bias and engage in strategic voting. By taking strategic voting into account in the study of campaigns, the present work builds a bridge between the campaigns effects literature and studies on strategic voting.

A német-francia kapcsolat változásai meghatározzák és jelölik a gazdasági gondolkodás újabb útjait, lehetőségeit középpontban az Európai Unió létével és sajátosságával. Vizsgálódásunk tárgyát ezért az a központi probléma szervezi meg, hogy miként küzdi ki a globális intézményrendszer válságaiban “az értékek párbeszédének termelését” mintegy a politikai gazdaságtanban – a politikai tudás szerepe az elidegenedéssel szemben – és hogy kik és hogyan vesznek részt a termelésben, és határozzák meg végsősoron, hogy mi az érték fogalma. Egy korábbi írásunkban a piac és a szakpolitika ellentéte mentén azon nyugvópontra jutottunk, hogy habár a piac nem képes az értékrendről folyó diskurzust artikulálni, mégis a kultúra szükségszerűsége mechanizmusként a törekvést önmagából fakadóan kifejezi. Úgy fogalmaztunk, hogy „a dekarbonizáció szakpolitikai tendenciái mintegy szükségszerűen artikulálják annak bekövetkeztét és mechanizmusát, hogy a világpiac helyén totálisan megszerveződik a következőkben bemutatkozó gazdaságpolitikai perspektíva, ami végső soron a termelés az értékek dialógusában.” (Lits és Lits, 2022) A cikk szerkezete a fentebb írtak okán a következőképpen alakul: Elsőként a politikai tudás és a politikai gazdaságtan szerkezeti adottságainak azon aspektusaira mutatnánk rá, melyek különös szerepet fejeznek ki a napjainkban megingó globális kormányzás megújulási folyamatában. Másodszor a német-francia viszony őszi felütésén és sajtóvisszhangján keresztül érintenénk a politikai tudás működését a gazdasági folyamatok megítélésében. Azt követően transzdiszciplináris megközelítéssel az Európa integrációját kiküzdő tervek gazdasági értelmezésére törekszünk az említett német-francia párbeszéd alakulásának tükrében, amit az elméleti kilátások, perspektívák egyszersmind kifejezése- és okozójaként működtetve azonosítunk összegzésünkben, hogy egyértelmű válaszként fogalmazzuk meg a politikai gazdaságtan elsőbbségét és kitüntetett szerepét az emberi működés helyreállításában, abban a törekvésben, mely a gazdaságot újra alrendszerré kívánja tenni az értékek dialógusában.

Authors: Vaisman Elena , Korotovskikh Andrey
Published: January 2023

In this work, a hypothesis is formulated according to which not only on the degree of suc-cess of the digital transformation projects, but also the impact of the latter on the value of the enterprise depend on the degree of readiness of an industrial enterprise. It is shown that the con-dition for the successful implementation of digital transformation is a combination of three components: the strategic readiness of an enterprise, which is expressed in the presence of rea-sonable strategic plans for the implementation of digital projects; psychological readiness, re-flecting the readiness of staff to change; and readiness in terms of resources, characterizing the state of the resources of an industrial enterprise. A methodological approach to assessing the lat-ter component has been developed, based on a coefficient called CRFD. The conducted appro-bation has shown that industrial enterprises with a higher CRFD coefficient demonstrate greater value of their value growth as a result of the implementation of digital projects.

Published: January 2023

The article presents a methodological approach to conducting an integrated complex dynam-ic assessment of the level of competence of an employee of an organization, including three stag-es. At the first stage, it is proposed to conduct a generalized assessment of the sustainability of the enterprise. Integrated dynamic assessment of the state of sustainable development of the enter-prise includes economic, environmental, social, institutional indicators. At the second stage, when forming an integral complex dynamic assessment of the employee's competence level, it is pro-posed to supplement the methodology of its calculation with an integral dynamic indicator of the organization's sustainable development assessment. The obtained integral complex assessments of competence are used to develop measures and guidelines for improving personnel manage-ment. At the third stage, an algorithm has been developed for material and moral incentives for professional development and labor efficiency to achieve the company's sustainable develop-ment goals using integrated complex dynamic assessments of competence during employee certi-fication. The approbation of the proposed approach to the integrated complex dynamic assessment of the level of competence of an employee of the organization was carried out according to the Integrated Annual Report of PJSC Magnitogorsk Iron and Steel Works. The practical significance of the developed methodology of a comprehensive dynamic as-sessment of competence in the certification of employees with the inclusion of the results of an in-tegrated dynamic assessment of the state of sustainable development of the enterprise will in-crease the effectiveness of decision-making to improve personnel management for the sustainable development of the company.

Authors: Korotina Natal'ya
Published: January 2023

The processes of the economic space reforming, considering regional interests, entail the transformation of the socio-economic systems of territories and give rise to an aggravation of contradictions between the central government and the subnational entities of the country, what requires theoretical understanding of the problems and expanding the theory of the economic mechanism of federative relations. The purpose of the article is to specify and substantiate the concept of the economic federalism, considering the heterogeneity of regions, the need for spatial connectivity and cohesion of territories. The main constructive provisions of the spatial economic federalism are highlighted: the integrating role of the public sector as an institutional construct and an economic actor; the need for connectivity and cohesion of heterogeneous (territorial, governing and economic) spaces of interaction of entities of federative relations; combination of universal and adaptive parts in the institutional model of economic federalism. A methodology has been developed and tested for comparing the consistency of the economic interests of entities of federative relations in the Russian Federation, both in the context of regions and territorial zones of different functional status (centers of economic growth, geostrategic territories, etc.). The identified trends of better consistency of interests within the territorial zones structure allow us to justify the need for a new strategic format and the application of the specificity of the support measures in the territorial-functional context, the combination of universal and space-oriented tools, what would ensure the coherence of space in the Russian model of economic federalism.

The article is devoted to the analysis of the ecosystem as an innovative business model. The use of modern business models is for many enterprises a driver for increasing competitiveness in a rapidly changing market environment, increasing market share and profits. The lack of an unambiguous, comprehensive definition of the concept of a business ecosystem and its unique principles that make it possible to identify this business model from others predetermined the purpose of this study. The purpose of the study is to identify and systematize the principles of functioning of business ecosystems that ensure the effectiveness of the use of current and projected ecosystems at domestic enterprises, including industrial ones. During the study, such economic definitions as system and ecosystem, business system and business model were analyzed. This made it possible to single out the universal and specific principles of the operation of business ecosystems as a whole, to form a system of principles for the functioning of a business ecosystem in industry to ensure the economic sustainability of industrial enterprises that are part of the ecosystem and increase the competitiveness of the industrial sector of the economy.

Published: January 2023

Usually, the main source of water is a river, which makes it essential to ensure that the water from that source is not polluted and in accordance with the water quality standards. Water quality can deteriorate as a result of domestic and industrial waste. This quality is measured based on several parameters, such as the concentration of pH, nitrate, phosphate, and fecal coliform in the water. QUAL2KW can be used to analyze river water quality in order to solve several water quality-related problems. The main river water source in Semarang Regency is the Klampok River, whose water is used to support agriculture, livestock, and other activities. This study aims to determine the concentration of the above-mentioned parameters in the samples from the Klampok River using QUAL2KW. The water samples are obtained from different six points on the Klampok River, and the chi-square test is used for validation. From the laboratory test results for the river-quality parameters, after being simulated using QUAL2KW and validated using the chi-square method, it can be concluded that the quality of the Klampok River belongs to class II. These results can be used as a reference by the Semarang Regency government in managing river water quality.

The study uses quantitative methods such as laboratory analysis for the water quality and PI calculation using a formula based on the Decree of the Minister of Environment No.115/2003 on determining water quality status. Meanwhile, the Strengths, Weakness, Opportunities, and Threats (SWOT) analysis generates recommendations for water pollution control strategies. The sampling locations are located in two sampling points (upstream and downstream of the Berenyok river) during bright daylight and the river's normal flow. Based on analysis results, the Berenyok river is defined as lightly polluted as the concentrations of several chemical parameters exceed the maximum limit, such as BOD, and PO3-P. It is also verified by high concentration of total coliform, namely 540,000 MPN/100mL (upstream) and 1,600,000 MPN/100mL (downstream). Thus, recommendations for water pollution control strategies are substantial for the Berenyok river.

The coal mining industry is an industrial activity that impacts the environment. This activity will generate acid mine drainage due to the interaction of water, air and sulfide minerals. Acid mine drainage is wastewater with low pH and heavy metals content. These conditions will be given some negatives impact on the environment and human health. The low-cost, applicable and simple method to solve acid mine drainage in mining areas is constructed wetlands. Hence, this paper aims to describe the potential of wetlands as a low-cost and applicable method for acid mine drainage treatment. This paper also describes the holistic information about an overview of constructed wetlands, acid mine drainage (AMD) production and their negative impacts, recent trends in constructed wetlands, recommendation components of wetlands, potential application in rural areas and future considerations
Why can’t I teach English? A case study of the racialized experiences of a female Ugandan teacher of English in an EFL context
Authors: Seo Youngjoo
Published: January 2023

Despite an increase in ethnic diversity within the country, the English language teaching workforce remains undeniably binary in Korea. Using an intersectionality lens, this study was an exploration of the racialized experiences of one Ugandan female teacher of English working in Korean ELT. Semi-structured interviews were conducted to investigate how she perceived herself as an English speaker and teacher and how Koreans’ stereotypes of ideal English teachers and Black people affected her professional identity and self-perceptions. Findings suggest that the Ugandan woman was rejected by the formal accreditation process and faced considerable challenges in her efforts to be accepted as a qualified English teacher in Korea. On the other hand, she perceived herself as a native-like English speaker and a fully qualified English teacher with an MA degree in TESOL and years of English teaching experience. This study reveals not only the practical difficulties of a biased assessment system, but also the narrow discourse concerning who can legitimately be recognized as an English teacher in Korea, which is at odds with the Korean policy of a pursuing multicultural society and honoring diversity and with the global trend of recognizing multiple English.
The relationships between young FL learners’ classroom emotions (anxiety, boredom, & enjoyment), engagement, and FL proficiency
Authors: Tsang Art , Dewaele Jean Marc
Published: January 2023

The last decade has seen a proliferation of studies about emotions in FL teaching and learning. The present study examined three of the most researched and well-known FL emotions to date, namely anxiety, boredom, and enjoyment, and their relationships with learners’ engagement in English-as-a-foreign-language (EFL) classes and their EFL proficiency. One hundred and eleven Grade 3–4 EFL children completed a questionnaire and English tests. Various statistical analyses (correlation, hierarchical multiple regression, and path analysis) revealed that all five variables were significantly inter-correlated. Enjoyment was the strongest predictor of engagement and proficiency, followed by boredom. The path analysis indicated that the hypothetical path of emotions→engagement→proficiency did not exist; rather, only two direct relationships were found in the model: Enjoyment→engagement and enjoyment→proficiency. The findings highlight the crucial role of enjoyment for young learners in FL teaching and learning.
The New Advocacy for Autarky: Self-Sufficiency is Now Once Again Becoming Popular for Geopolitical Reasons
Authors: Dieter Heribert , Biedermann Johanna
Published: January 2023

International economic relations and trade in particular have been thriving since World War II. Whilst the lowering of trade barriers and the dismantling of trade restrictions have long enjoyed support both among trade economists and policymakers, there has recently been a swing back to protectionist policies. In virtually all major economies, a surprising new interest in autarky can be observed. Today, both the USA and the member countries of the European Union prioritize domestic production of certain products, especially semiconductors. China has taken a decisive turn to trade policies that emphasize self-sufficiency and domestic production. India, which has long favoured sourcing from domestic producers, has at least partially embraced self-sufficiency. We analyze and add a historical lens to these recent developments. If they will continue, we argue that the world will see negative effects on welfare if these trends continue unchecked.
A new sand raining technique to reconstitute large sand specimens
Authors: Al-Yasir Abdullah Talib , Al-Taie Abbas Jawad
Published: January 2023

Sand raining is among the popular techniques used in the laboratory for preparing sand samples. Factors like the deposition intensity (DI) and the falling height (HF) affect the produced relative density (RD) in this technique. Studies showed that the RD increase as the HF increases. This is, however, applicable up to a critical HF beyond which the RD seems unaffected. According to previous experiments, the maximum RD achieved using the sand raining is about (70 ± 5)%. The preparation of samples with higher RD is a prerequisite required in many experimental models. In the present article, a new raining system, which is capable to prepare sand samples with a very high RD and with a fast sand flow, is introduced. The new system was used to examine the relationship between the HF and the RD under different trapped air pressures and using rain nozzles with three different opening diameters. The new system was found appropriate for reconstituting SP-SM with very dense specimens (RD > 99%) with achieving higher DI values and a reduction in preparation time of more than 90% in comparison to the classic raining technique. It is time-saving and very suitable to reconstitute large model soil specimens effectively and quickly.

Понятие чудо и его интерпретация (на материале анкет студентов польско-белорусского Пограничья)
Authors:   Uniwersytet w Białymstoku, Anchimiuk Olga
Published: January 2023

The article presents the results of a survey conducted to identify the main features of the concept of ‘miracle’ and to explore its interpretation in the consciousness of young people belonging to different national and cultural groups. The survey was conducted among students of Borderland Universities – the University of Bialystok (UwB) and the Yanka Kupala State University of Grodno. The aim of the research was to determine, by means of a questionnaire, the common and separate elements in the understanding of the term ‘miracle’ by Polish and Belarusian students. Research methods: descriptive, dictionary definition analysis, interpretative, component analysis, quantitative calculations. As the study showed, the meanings of ‘miracle’ are much broader than the explanatory dictionaries indicate. The connection between miracle and God in most terms was observed among UwB students, which probably results from greater religiosity and the preservation of religious traditions in Poland. The secularization of society, which covered the territory of Belarus in the previous period, influenced the views of contemporary students in this field and was a decisive factor in the perception of the phenomenon in question.
