Published: June 2023

Shifting learning process due to COVID-19 has led to increased burnout prevalence among medical students. Thus, this study aimed to assess burnout prevalence and its associated factors among Indonesian medical students during the COVID-19 pandemic. An online cross-sectional study was carried out among medical students in Malang, Indonesia. Burnout was assessed using the Maslach Burnout Inventory-Student Survey tool. Pearson’s Chi-square was used to assess significant associations, and binary logistic regression was conducted to evaluate the relationships between the predictor variables and burnout. The difference of each subscale score was evaluated using an independent sample t test. This study analyzed 413 medical students with a mean age of 21.1 ± 1.4 years old. About 29.5% and 32.9% of students reported a high level of emotional exhaustion and depersonalization, respectively, resulting in 17.9% of burnout prevalence. Stage of study was the only sociodemographic factor independently associated with burnout prevalence (odds ratio = 0.180, 95% confidence interval = 0.079–0.410, p-values = 0.000). Preclinical students had significantly higher levels of emotional exhaustion (p-value = 0.004, d = 0.3) and depersonalization (p-value = 0.000, d = 1.1), and lower levels of personal accomplishment (p-value = 0.000, d = -0.5). Around one-sixth of the medical students experienced burnout during the COVID-19 pandemic, with preclinical students being more prone to have burnout. Future study with other adjusted confounding factors is needed to completely understand the issue and obtain immediate interventional strategies to reduce burnout among medical students.
A registered report of a crossover study on the effects of face masks on walking adaptability in people with Parkinson’s disease and multiple sclerosis
Authors: Eschweiler Mareike , McCrum Christopher , Giannouli Eleftheria
Published: June 2023

Background

Face masks protrude into the lower visual field causing reduced perception of visual stimuli, potentially making obstacle avoidance during walking more difficult and increasing fall risk. Recommendations on walking and mask wearing for older adults have been debated, with no clear consensus on the various factors interacting and influencing walking safety while wearing a face mask. It is particularly important to address this issue in populations at an increased risk of falls. Therefore, this study aims to investigate the effects of mask-wearing on objectively measured walking adaptability in people with Parkinson’s disease and Multiple Sclerosis.

Methods

50 patients with either Parkinson’s disease or Multiple Sclerosis attending inpatient neurorehabilitation will be recruited to participate in this crossover study. Performance during a standardized gait adaptability (C-Gait) test on a VR-based treadmill (C-Mill+VR), as well as during clinical mobility tests (10-meter walk test, Timed Up & Go test, and stair ambulation) will be measured with and without an FFP2- mask (order randomized). In addition, participants will be asked about their perceived performance and perceived safety during the tests with and without a mask. Performance on the seven C-Gait subtests is based on centre of pressure-derived measures of foot placement in relation to the different tasks. These are averaged and added to a cognitive C-Gait task to give the overall composite score (primary outcome). Secondary outcomes will include the different subscores and clinical mobility tests.

Potential significance

This study will make an important contribution to an ongoing debate regarding recommendations persons with and without a neurological disease should be given regarding wearing a face mask while walking. Furthermore, the study will complement the existing scientific discourse with clinical data from people with a neurological disease for whom falls, mobility deficits and mask wearing may be more frequent, which can help inform evidence-based recommendations.

World beliefs, character strengths, and hope for the future
Authors: McGrath Robert E.
Published: June 2023

Research in recent years has revealed the rate of premature and avoidable deaths from suicide and drug/‌alcohol misuse is rising in the United States. These are sometimes referred to as deaths of despair based on evidence that they are concentrated in relatively poor communities with less access to social resources and low labor force participation. The pattern was first noted in middle-aged White men but seems to be gradually spreading to other ethnic groups. As a first step in establishing a psychological response to this public health issue, the present article summarizes two studies that compared psychological variables to demographics as predictors of hopefulness. A number of intriguing findings emerged. Despite concerns about American despair and conflict, U.S. residents proved the most hopeful among residents of eight countries. Low-income Americans are particularly hopeful except for low-income Whites. Positive character traits and primal beliefs about the world generally proved to be better predictors of hope than ethnicity, financial status, or their interaction. A number of relationships were found between psychological variables and community demographics. The findings as a group suggest hopefulness is driven more by psychological variables than by life circumstances. It is suggested that psychologists could play an important role in the study of this topic by implementing programs intended to enhance hopefulness in impoverished populations, and by encouraging an intentional communal focus on the importance of enhancing well-being.

Published: June 2023

Introduction

Abortion is a common gynecological procedure and plays a central role in women’s health and autonomy. To maintain accessibility to abortion, it is important that sufficient obstetrics and gynecology (Ob/Gyn) residents intend to provide abortion care after residency. This study identifies factors that influence a resident’s intention to provide abortions (IPA) post-training.

Materials and methods

A multiple-choice survey, addressing demographics, religious background, residency program metrics, training experience and intent to provide abortions (IPA), was answered by 409 Ob/Gyn residents. Chi-square test was performed on descriptive statistics and continuous variables were tested with ANOVA with p<0.05 considered significant.

Results

Residents with IPA were predominantly female (p = 0.001), training in the Northeast and West (p<0.001), identifying either as non-religious, agnostic/atheist or Jewish (p<0.01), not actively practicing their religion (p<0.001) and leaning democrats (p<0.002). Those with IPA were more likely to train at hospitals without religious affiliation (p<0.008), to train at a Ryan Program (p<0.001), to place strong emphasis on choosing a program with family planning training (p<0.001), to join programs where a significant portion of the faculty performs abortions (p<0.001) and to have completed a higher number of first trimester medical and surgical abortion procedures during the last six months of training (p<0.001).

Conclusion

These results suggest that factors influencing a physician’s intention to provide abortions are multifactorial, involving personal and program factors. A model predicting IPA is derived. To maximize IPA, residency programs can increase abortion volume, facilitate additional training and build a supportive faculty.
Optimal pricing and carbon emission reduction decisions for a prefabricated building closed-loop supply chain under a carbon cap-and-trade regulation and government subsidies

Published: June 2023

This paper explores a two-level prefabricated building closed-loop supply chain (CLSC) comprising a retailer and a prefabricated building manufacturer (PBM) under carbon cap-and-trade legislation and the government subsidies of carbon emission reduction (CER). In this CLSC, the PBM and the retailer recycle used products through their independent recycling channels. The optimum pricing and CER strategies within both decentralized and centralized systems, respectively, are analyzed. The Stackelberg game is used in the decentralized system to determine the optimum PBM’s CER level and the retailer’s pricing. By analysis, it concludes that increasing the carbon trading price can stimulate prefabricated construction corporations to improve their CER level, and that the government subsidy rate has a great effect on the profits of the PBM. Numerical examples with sensitivity analysis are used to further evaluate the roles of important factors in the optimum CER and pricing solutions of the prefabricated building CLSC in two dissimilar systems.
Measures to sustain endangered languages: A bilingual competition model with sliding mode control
Authors: Gao Ya , Liu WenQi
Published: June 2023

There are thousands of languages in the world, many of which are in danger of extinction due to language competition and evolution. Language is an aspect of culture, the rise, and fall of a language directly affects its corresponding culture. To preserve languages and prevent their mass extinction, it is crucial to develop a mathematical model of language coexistence. In this paper, we use a qualitative theory of ordinary differential equations to analyze the bilingual competition model, and obtain the trivial and non-trivial solutions of the bilingual competition model without sliding mode control, then analyze the stability of solutions and prove that solutions of the model have positive invariance. In addition, to maintain linguistic diversity and prevent mass extinction of languages, we propose a novel bilingual competition model with sliding control. The bilingual competition model is analyzed by proposing a sliding control policy to obtain a pseudo-equilibrium point. Meanwhile, numerical simulations clearly illustrate the effectiveness of the sliding mode control strategy. The results show that the likelihood of successful language coexistence can be increased by changing the status of languages and the value of monolingual-bilingual interaction, provides theoretical analysis for the development of policies to prevent language extinction.

Published: June 2023

Introduction

According to several studies, a specific dietary pattern can reduce the risk of dementia and cognitive impairment. However, the robustness of these results has not been tested. The study intends to investigate the association between nutrition intake and cognitive impairment in middle-aged and older adults (≥45-years) and provide reliable, evidence-based references for healthcare decision-makers, researchers, and policymakers.

Review question

Are the dietary characteristics of community-dwelling adults (≥45-years) associated with the occurrence of cognitive impairment?

Objectives

The primary objective of this protocol is to synthesize the longitudinal observational evidence on the relationship between nutrition intake patterns and the incidence of cognitive impairment in middle-aged and older adults (≥45-years), and to provide detailed dietary recommendations for the prevention of cognitive impairment in this population.

Methods and analysis

Cohort studies conducted among adults (≥45-years) will be included. The following electronic databases will be searched for relevant records published by July 2023, with a restriction on language to English: Pubmed, Medline, Embase, Web of science, Cochrane Library. The studies will be selected, the data will be extracted, and the bias risk will be assessed by two independent investigators. The Meta-analysis of Observational Studies in Epidemiology guidelines will be followed to summarize observational studies, and the protocol will adhere to the recommendations from the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols 2015 statement. Endnote X9 will be used to manage data screening. We will use Review Manager 5.4 and Stata 16.0 to conduct data analysis, and a random-effects model will be applied to pool clinically homogenous studies. The results will be presented based on the form of nutrition intake. For assessing publication bias, Egger’s test and visual inspection of funnel plots will be utilized.

Ethics and dissemination

As this study does not involve primary data, ethical approval is not required. The final report will be published in a peer-reviewed journal.

Reflective practice improves Basic Life Support training outcomes: A randomized controlled study
Authors: Thommes Marie S. , Schmidt Michelle , Lambert Sophie I. , Schauwinhold Michael T. , Klasen Martin , Sopka Saša
Published: June 2023

Introduction

Practical skills training is an essential part of medical education. An important example is the training of Basic Life Support (BLS) skills, which are key to improve patient outcomes in life-threatening situations. However, despite practical training, BLS performance is often sub-optimal even among healthcare professionals and medical students. Finding more effective training methods is therefore of high importance. A promising method to enhance learning outcomes is reflective practice. The goal of the present study was to evaluate whether a short reflective practice intervention following standard BLS training (Peyton’s 4-step approach) improves BLS training outcomes, reflected in higher BLS performance and higher self-confidence to perform BLS.

Method

287 first-year medical students were randomly assigned to one of two BLS training conditions: 1) standard BLS training (ST), 2) ST followed by a 15-minute reflective practice exercise. Outcome parameters included objective BLS performance data assessed by a resuscitation manikin, and students’ self-reported confidence in their BLS skills. Outcomes were assessed directly after the training (T0) and re-assessed one week later (T1). A two-way mixed model analysis of variance (ANOVA) was conducted to examine the effect of the intervention on BLS performance and self-reported confidence. Significance was determined by two-sided 95% confidence intervals.

Results

The intervention group performed significantly more effective compressions at T1 and began significantly faster with performing their first chest compression at T0 and T1, in comparison to the control group. No significant differences between study groups regarding their self-reported confidence to perform BLS were observed.

Conclusion

This research shows that standard BLS training accompanied with a simple, cost-effective reflective practice exercise can improve learners’ BLS skill acquisition and retention. This shows that reflective practice has the potential to enhance practical skills training in medicine; yet, more empirical studies are needed to examine its broader applicability.
Exploring the effect of industrial agglomeration on income inequality in China
Authors: Zhang Suhua , Bani Yasmin , Izah Selamat Aslam , Abdul Ghani Judhiana
Published: June 2023

Income inequality is a good indicator reflecting the quality of people’s livelihood. There are many studies on the determinants of income inequality. However, few studies have been conducted on the impacts of industrial agglomeration on income inequality and their spatial correlation. The goal of this paper is to investigate the impact of China’s industrial agglomeration on income inequality from a spatial perspective. Using data on China’s 31 provinces from 2003 to 2020 and the spatial panel Durbin model, our results show that industrial agglomeration and income inequality present an inverted “U-shape” relationship, proving that they are the non-linear change. As the degree of industrial agglomeration increases, income inequality will rise, after it reaches a certain value, income inequality will drop. Therefore, Chinese government and enterprises had better pay attention to the spatial distribution of industrial agglomeration, thereby reducing China’s regional income inequality.

Introduction

Globally, noncommunicable diseases (NCDs), which include type 2 diabetes (T2D), hypertension, and cardiovascular disease (CVD), are associated with a high burden of morbidity and mortality. Health disparities exacerbate the burden of NCDs. Notably, rural, compared with urban, populations face greater disparities in access to preventive care, management, and treatment of NCDs. However, there is sparse information and no known literature synthesis on the inclusion of rural populations in documents (i.e., guidelines, position statements, and advisories) pertaining to the prevention of T2D, hypertension, and CVD. To address this gap, we are conducting a systematic review to assess the inclusion of rural populations in documents on the primary prevention of T2D, hypertension, and CVD.

Methods and analysis

This protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched 19 databases including EMBASE, MEDLINE, and Scopus, from January 2017 through October 2022, on the primary prevention of T2D, hypertension, and CVD. We conducted separate Google® searches for each of the 216 World Bank economies. For primary screening, titles and/or abstracts were screened independently by two authors (databases) or one author (Google®). Documents meeting selection criteria will undergo full-text review (secondary screening) using predetermined criteria, and data extraction using a standardized form. The definition of rurality varies, and we will report the description provided in each document. We will also describe the social determinants of health (based on the World Health Organization) that may be associated with rurality.

Ethics and dissemination

To our knowledge, this will be the first systematic review on the inclusion of rurality in documents on the primary prevention of T2D, hypertension, and CVD. Ethics approval is not required since we are not using patient-level data. Patients are not involved in the study design or analysis. We will present the results at conferences and in peer-reviewed publication(s).

Published: June 2023

A pandemia agravou o risco de adoecer psicológico nos profissionais de emergência médica (PEM), aumentando os seus níveis de trauma, stress e ansiedade. Estes indicadores psicológicos têm sido estudados nos enfermeiros e médicos, mas são pouco investigados nos PEM. Pretende-se apresentar uma revisão da literatura sobre o impacto da pandemia COVID-19 nos PEM, com particular ênfase na saúde mental/psicológica. Em abril de 2022 efetuou-se uma pesquisa na EBSCOhost, utilizando a equação de pesquisa: “paramedic* or emergency medical service or EMT or ambulance” e “covid-19 or coronavirus or 2019-ncov or sars-cov-2 or cov-19”. Foram encontrados 58 artigos publicados entre 2020 e 2022, sendo selecionados 30, analisados em função da amostra, indicadores psicológicos, principais resultados e objetivos (foco nas diretrizes médicas e procedimentos/instrumentos para proteção ou no estudo da saúde mental e sintomas psicológicos). Os resultados apontam para a falta de estudos sobre a saúde mental destes profissionais durante a pandemia. É fundamental monitorizar a saúde mental/psicológica destes profissionais, nomeadamente devido à duração e impacto causado pela pandemia.

Published: June 2023

A COVID-19 se constituiu com um dos mais trágicos e impactantes desastres dos últimos anos, provocando a morte de cerca de 700.000 brasileiros. Neste artigo, de natureza qualitativa e descritiva, predominantemente baseado em análise documental, faz-se a revisão de aspectos relacionados com a teoria e prática dos Planos de Contingência. Analisa-se como, tanto a nível federal como no estado de SC, a resposta foi conduzida com base em planos setoriais (de saúde) e não um plano integrador, como teria sido desejável e como o Sistema de Comando foi frágil, desintegrado e, por vezes, contraditório. Debatem-se as implicações negativas desta realidade, em especial, a resposta à pandemia em outros setores que não o das instituições de saúde. Apresenta-se uma experiência desenvolvida no sul do Brasil centrada na elaboração do Plano de Contingência para a Educação (retorno às atividades presenciais). Além do modelo e lógica do plano, descreve-se o ambiente colaborativo interinstitucional de sua elaboração e o processo de formação em cascata de agentes de disseminação em todos os municípios catarinenses. Finalmente, retiram-se importantes conclusões para eventos futuros de natureza similar.

Open data policy, connectivity and portfolio determine brand popularity in e-commerce channel
Authors: Hoogeveen Martijn
Published: June 2023

Content marketing is increasingly important for brand performance, i.e., brand popularity and associated e-commerce sales. Content marketing factors that are seen as effective for brand popularity in the e-ecommerce channel are open data syndication policies, connectivity to e-commerce platforms, reviews, data completeness, and a brand’s online product portfolio.

We used brand popularity, reviews and catalog data in combination with product reviews from a global panel of 3,057 e-commerce platforms (n = 333 manufacturing brands). Through stepwise backward multiple linear regression five highly significant predictive factors for online brand popularity are selected in our content marketing model: the brand’s data syndication policy, the number of connected e-commerce platforms, a brand’s number of products, its number of products per category and the number of product categories in which it is active. The model explains 78% of the variance of brand popularity and has a good and highly significant fit.
Returns to Longevity? The Effects of Life Expectancy on Labour Productivity in Singapore.
Authors: Ng Wei Yang Shaun
Published: June 2023

While Singapore has consistently been at the forefront of global rankings when it comes to life expectancy and labour productivity, their relationship and interconnectedness are widely contentious. This paper attempts to specifically analyse whether life expectancy affects labour productivity through an instrumental variable approach using 2-Staged-Least-Sqaures (2SLS) regressions. I analyse the effects of life expectancy on labour productivity through multiple channels - education, savings, and the interaction between Malthusian effects and demographic transitions. While further controls must be considered to establish causality, this paper shows a positive association between life expectancy and labour productivity, shedding light that policy investments in health outcomes extend beyond demographic risk management to one which contemporaneously strengthens labour productivity.
A Simple and Effective Purification Method for Removal of U(VI) from Soil-Flushing Effluent Using Precipitation: Distillation Process for Clearance
Authors: Lee Hyun-Kyu , Kim Ilgook , Yoon In-Ho , Park Wooshin , Chang Seeun , Jeon Hongrae , Park Sungbin
Published: June 2023

Background: The purpose of this study is to purify uranium (U[VI])-contaminated soil-flushing effluent using the precipitation–distillation process for clearance. Precipitation and distillation are commonly used techniques for water treatment. We propose using a combination of these methods for the simple and effective removal of U(VI) ions from soil-flushing effluents. In addition, the U concentration (Bq/g) of solid waste generated in the proposed treatment process was analyzed to confirm whether it satisfies the clearance level.Materials and Methods: Uranium-contaminated soil was decontaminated by soil-flushing using 0.5 M sulfuric acid. The soil-flushing effluent was treated with sodium hydroxide powder to precipitate U(VI) ions, and the remaining U(VI) ions were removed by phosphate addition. The effluent from which U(VI) ions were removed was distilled for reuse as a soil-flushing eluent.Results and Discussion: The purification method using the precipitation–distillation process proposed in this study effectively removes U(VI) ions from U-contaminated soil-flushing effluent. In addition, most of the solid waste generated in the purification process satisfied the clearance level.Conclusion: The proposed purification process is considered to have potential as a soil-flushing effluent treatment method to reduce the amount of radioactive waste generated.
Antimicrobial Active Chitosan-Based Cotton Yarns: Effect of Chitosan Solution Concentration
Authors: Toshikj Emilija , Petrovski Ognen , Petrovska Milena , Jordanov Igor
Published: June 2023

Using the exhaustion-pad-dry-rinse method, chitosan was applied to alkaline-scoured and bleached cotton yarns in a solution with concentrations ranging from 0.2–1% to achieve good antimicrobial activity against the bacteria Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive). Studied samples were also assessed by measuring the amount of introduced chitosan, amount of accessible amino groups, mechanical properties, whiteness index and the b* colour coordinate. Alkaline-scoured and bleached cotton yarns treated with all concentrations of the chitosan solution showed good antimicrobial activity against Escherichia coli and Staphylococcus aureus. Better antimicrobial activity was achieved against Escherichia coli. Increasing the concentration of chitosan solution deteriorated the mechanical properties of chitosan-treated cotton yarns. The optimal concentration of chitosan solution incorporated in the exhaustion phase to obtain chitosan-treated yarns with good antimicrobial activity and mechanical properties was 0.6%. The best antimicrobial treatment should minimise potential economic costs while providing functionality.

The article traces the process of elaboration of education policies in women’s education in the Northwest of the Russian Empire by different agents of the imperial state on the central and local levels in the 1830s–1860s. The principal goal is not the history of education in a gendered perspective but rather the history of female social roles and national differences in this troubling imperial borderland. The ethnic and confessional markers of difference in the analysis aimed at producing a complex and dynamic picture of conjuncture of social, national, and gender discourses as well as idiosyncratic local considerations in contradictory efforts of imperial social engineering are complicated by the gender marker.
The Influence of J.A. Comenius’ Ideology on the Development of Slovak Pedagogy
Authors: Cabanova Vlasta
Published: June 2023

Pedagogical opinions of J. A. Comenius and his unique reflections on the improvement of the society represent one of the main standpoints for the development of humanist pedagogy around the world. His concept of education as well as his ideas on how to resolve many of the world’s complex problems were at the time highly progressive and have influenced the society’s way of thinking in Slovakia as well. The credit for the popularisation of his ideas goes to many notable personalities in Slovakia in the 19th and 20th centuries. His ideas are still tangible in the process of contemporary teaching of pedagogues, from primary schools all the way to universities.
Sprawa Mary Ellen Wilson i pierwsze amerykańskie organizacje na rzecz ochrony praw dziecka
Authors: Wojniak Justyna
Published: June 2023

The paper presents the mechanisms that led to the first American legal regulations and organizations for the protection of minors and the elimination of child abuse. The background for the considerations is the case that shocked the American public opinion in the second half of the 19th century. It concerned a 10-year-old girl, Mary Ellen Wilson, who was a victim of violence and neglect on the part of her guardians. The attempts to save the child showed that the American system of social welfare lacked adequate institutional and organizational instruments to protect a child who was a victim of violence and abuse.Based on the literature and available archival materials – official documents and press publications from the discussed period – the course of the trial was reconstructed, as well as the initiatives undertaken after its completion, which led to the establishment of the first American organization aimed to protect children. The summary presents the characteristics of the American movement for the protection of children against the background of European initiatives undertaken in this field.

EFL teacher agency in mediating the socialisation of multilingual learners
Authors: Rokita-Jaśkow Joanna
Published: June 2023

English as a Foreign Language (EFL) teachers are seemingly ideally placed to mediate the successful socialisation of multilingual learners into the new school environment for two major reasons. Firstly, as they have effective command of both L1 and L2 and often have experience of living abroad, they tend to exhibit higher levels of openness to new situations, empathy and understanding of the difficulties faced by multilingual learners. Secondly, the English class can itself be a platform for mutual understanding where learners are able to develop both English communication skills and intercultural competence (cf. Hopp, Jakisch, Sturm, Becker & Thoma 2020; Krulatz, Neokleous & Dahl 2022). As English is the language of instruction, it also has the potential to maintain levels of multilingual competence among those learners who already speak English as their heritage language (Banasiak & Olpińska-Szkiełko 2021), e.g. migrant children returning from the UK/Ireland. Drawing on data from a larger project (Rokita-Jaśkow, Wolanin, Król-Gierat & Nosidlak 2022), which consisted of interviewing 23 primary school EFL teachers in various contexts, this paper analyses the possible factors that impact teacher agency in the socialisation of multilinguals. It has been found that teacher agency in that respect appears to stem from teachers’ plurilingual competence and prior teaching experience. Surprisingly, personal experiences of intercultural encounters (e.g. time spent living abroad) or verbalised empathy, had little impact on teacher agency. This finding implies that even language teachers find it difficult to put themselves in the position of the multilingual learner and need specialist training in order to work with multilingual learners, which may convey an important message for educational decision-makers with reference to the formulation of future teacher education guidelines and curricula.

Place de la langue première et des approches plurielles dans les manuels de FLE du niveau secondaire en Pologne
Authors: Chmiel-Bożek Halina
Published: June 2023

The Council of Europe has been promoting pluralistic approaches for more than 20 years, considering them as an effective tool for the development of plurilingual competence, regarded as indispensable in multilingual Europe. The aim of the article is to determine the place of the first language and pluralistic approaches in the latest (published after 2018) French textbooks for high schools. The analysis shows that elements characteristic of pluralistic approaches are present in varying degrees in the textbooks analysed, both at the textual and paratextual level. Textbook authors use pluralistic approaches in a variety of ways, for example by referencing the knowledge of Polish, English as well as non-verbal language.

Key challenges related to smart villages
Authors: Niewiadomska Agata
Published: June 2023

The aim of the considerations was to identify the challenges related to smart villages arising in the Polish and European legal systems. The expansion of the smart villages concept has become more apparent the new Common Agricultural Policy which provides for the development of different legal mechanisms which, put together, will help to create a smart village. The legal, but also social and economic challenges related to this proposal have been indicated and supported by examples of the implementation of innovative villages in selected European countries, taking into account the influence of globalisation and Europeanisation on the very concept of intelligent villages. Further to that, potential threats from the adopted solutions, as well as their impact on the competitiveness of agriculture have been highlighted. It has also been shown that intelligent villages constitute one of the transmitters of innovation in agriculture and digital rural development.
Dysfunkcjonalność pojęcia gospodarstwa rodzinnego w ustawie o kształtowaniu ustroju rolnego
Authors: Leśkiewicz Katarzyna
Published: June 2023

Przesłanką leżącą u podstaw prowadzonych rozważań jest twierdzenie, że pojęcie gospodarstwa rodzinnego przewidziane w ustawie o kształtowaniu ustroju rolnego jest dysfunkcjonalne. W pierwszej kolejności przedstawiono teoretyczne aspekty definiowania pojęć i ich funkcji, a następnie dokonano analizy pojęcia gospodarstwa rodzinnego na tle jego ujęcia w regulacjach innych państw. Następnie stwierdzono, że wadliwe zdefiniowanie tego pojęcia utrudnia realizację funkcji ochronnej gospodarstwa rodzinnego, jaką jest zabezpieczenie rodzinnego charakteru gospodarstw rolnych, ich dochodowości i efektywności. Analiza stabilizujących i dynamizujących funkcji definicji gospodarstwa rodzinnego daje również podstawę do twierdzenia, że definicja ta nie posiada cech, które sprzyjałyby wzmocnieniu takich gospodarstw i zwiększeniu ich efektywności ekonomicznej. Wadliwa definicja gospodarstwa rodzinnego uniemożliwia zadowalającą ochronę wartości określonych w Konstytucji, a w konsekwencji utrudnia realizację celów ustawy o kształtowaniu ustroju rolnego w Polsce.
A longitudinal study on students’ self-regulated listening during transition to an English-medium transnational university in China
Authors: Zhou Sihan , Thompson Gene
Published: June 2023

Listening to academic content in English medium instruction (EMI) classrooms at university can be a demanding task for students who transition from first language (L1) instructed secondary schools. This longitudinal mixed methods study analyzes data from 316 students collected at the beginning, midterm, and the end of their first semester after entering an EMI transnational university in southeast China. The analysis of questionnaire responses revealed significant variations in students’ listening strategies over time, with a significant decrease in deep processing cognitive strategies at the midterm when content difficulty increased. Conversely, two types of metacognitive strategies (problem solving, plan evaluation) increased significantly during the second half of the semester. Informed by Zimmerman’s (2000) social cognitive self-regulated learning (SRL) model, thematic analysis of semi-structured interviews with 34 participants revealed that students generally developed a more top-down listening approach focusing on content learning over the semester and became more selective in their strategic and self-regulatory processes after the midterm “watershed” moment. Results highlight the importance of structured topic knowledge in EMI curriculum design and the necessity of strategy training in language support programs.
Deutsche Fachsprache der Architektur und des Bauwesens: Struktur und Semantik
Authors: Kiyko Svitlana , Rubana Yevheniia
Published: June 2023

The article deals with the study of structural and semantic features of the German professional language of architecture and construction. The study is based on the main principles of structural-semantic linguistic paradigm and represents the modeling of terminology in the form of a thesaurus with its multilevel classification structure. Achieving the main goal involves the selection of various structural types of terms and phrases, the analysis of key terms and their semantic fields and the study of possible logical-semantic relations in the proposed German professional language. The study was conducted in four stages. The first stage included an explanation of the main approaches to the study of both terminological systems of professional languages and individual terms. The second stage consisted in the analysis of logical-conceptual relations between terms, such as hypero-hyponymy, subcontracting as well as relations concerning the localization of the object, its purpose, etc. At this stage, terminology is considered as a thesaurus, taking into account the specifics of the organization of the studied branch of knowledge and the lexical-semantic field of the key terms of architecture and construction. The third stage was based on the structural and morphological analysis of the terms and included a description of structural models of terms. The last stage concerned the formulation of the conclusions of our study.
