Authors: Singh Devendra Raj , Sah Rajeeb Kumar , Simkhada Bibha , Darwin Zoe
Published: November 2024

Background

Stakeholder engagement is widely considered democratic, transparent, and essential in the shared decision-making process for improving health services. However, the integrated evidence of stakeholders’ engagement activities in maternal and newborn health (MNH) services in the context of low- and middle-income countries (LMICs) is lacking. Therefore, this review aims to generate synthesised evidence of different practices for stakeholder engagements, characteristics of stakeholder engagements and outcomes of stakeholder engagements in improving the MNH services uptake and delivery.

Methods

The systematic review reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) checklist. The literature was searched in PubMed, CINAHL, PsycINFO, Science Direct and Scopus databases. The identified records were screened using Covidence software, and data were extracted from included records using a predefined template. The mixed methods appraisal tool was used to assess the quality of the included studies. The spectrum of stakeholder engagement provided by the International Association for Public Participation (IAP2) was used as a guiding framework for synthesising the evidence related to stakeholder engagement.

Results

A total of 1473 records were identified through the initial search after removing the duplicates. Twenty-six studies were included in the final review. The review results related to service users and other stakeholders’ engagement are presented under three overarching themes: (i) Methods and contexts of stakeholders’ engagement, (ii) Outcomes of stakeholders’ engagement, and (iii) Facilitators and barriers to stakeholders’ engagement.

Conclusion

Various participatory approaches were utilised to engage the service users and other stakeholders in improving MNH service uptake and delivery. A wide range of service user- and provider-led outcomes were identified due to stakeholder engagement.

The integration of endomycorrhizal fungi into agricultural practices as inoculum offers the potential to improve plant productivity while reducing reliance on expensive chemical fertilizers, which are not only economically costly but also detrimental to the environment. Mycorrhizal fungi play a crucial role in facilitating plant access to essential mineral elements (such as Phosphorus, Potassium, etc.) and water, particularly in soils characterized by arid and semi-arid conditions. where these resources are often limited. Despite the obvious advantages, the development of arbuscular mycorrhizal fungi (AMF) inoculum production in Africa is progressing on a small scale. This research aims to address this limitation by exploring the feasibility of producing mycorrhizal inoculum on a semi-industrial farm scale, achieved through the control and stabilization of production parameters. Crop residues as peanut shell, rice husk, sugar cane bagasse and millet ears were tested in Leonard jars and pots as alternatives to conventional sand production substrate for the multiplication of mycorrhizal fungi Glomus aggregatum IR27, Funneliformis mosseae, Rhizophagus irregulares and Glomus fasciculatum R10. Significant results were obtained on the peanut shell. Under mass production conditions in farm scale, Glomus aggregatum IR27 showed the best mycorization characteristics with 19.76% intensity and 88.93% frequencies. The study highlighted the critical considerations of irrigation water salt content and substrate sterilization as essential parameters to ensure optimal development of mycorrhizal propagules. Water containing 0.5% salt inhibited the mycorrhization. This negative effect of salt was much more accentuated in unsterilized peanut shell substrate than in sterilized one. This experimental study constitutes a pioneering initiative, potentially replicable in other agricultural areas. Its sustainability is based on the simplicity and efficiency of the technology, which opens the prospect of increasing the number of AMF inoculum production units on a national scale in Senegal.

Published: November 2024

Non-High-Density Lipoprotein Cholesterol to High-Density Lipoprotein Cholesterol Ratio (NHHR) is a significant indicator of atherosclerosis. However, its association with diabetic kidney disease (DKD) remains unclear. This study aims to explore the relationship between NHHR and the prevalence of DKD among the U.S. adults using data from the National Health and Nutrition Examination Survey (NHANES) spanning 1999 to 2020. Participants were selected based on the stringent inclusion and exclusion criteria. We utilized single-factor analysis, multivariate logistic regression, and smooth curve fitting to investigate the relationship between NHHR and DKD. Our study included 8,329 diabetic individuals, who were categorized into DKD and non-DKD groups based on the presence or absence of kidney damage. A significant difference in NHHR was observed between these groups. After adjusting for potential confounders, we found that NHHR was positively associated with the prevalence of DKD. Specifically, each one-unit increase in NHHR corresponded to a 6% rise in the prevalence of DKD, with this association remaining significant across stratified NHHR values. Threshold effect analysis revealed an inflection point at an NHHR of 1.75, beyond this point, each unit increase in NHHR was associated with a 7% increase in the prevalence of DKD. Subgroup analysis confirmed the robustness of these findings. Our study demonstrates a significant correlation between NHHR and DKD prevalence, suggesting that monitoring NHHR could be an effective strategy for reducing DKD prevalence.

Published: November 2024

The roots and rhizomes of Panax ginseng C.A. Mey are commonly used herbal medicine in Asian countries. These components contain a large number of secondary metabolites known as ginsenosides, which serve as primary active ingredient. Environmental factors significantly influence the production of secondary metabolites, which are crucial for enhancing plant adaptability to ecological stress. P. ginseng is a shady plant that thrives in a constantly humid and temperate environment. However, it cannot withstand excessive moisture, making soil moisture a significant ecological stress affecting P. ginseng survival. In this study, we applied a water spray to maintain a water-saturated surface on 5-year-old fresh P. ginseng roots for a duration of 5 days, to establish a short-term water stress condition. The results revealed a notable increase in superoxide anion (O2·-), hydrogen peroxide (H2O2), and NADPH oxidase (NOX) activity (p < 0.01), as well as malondialdehyde (MDA) contents (p < 0.01) in both the main root and fibrous root of P. ginseng. Additionally, superoxide dismutase (SOD), catalase (CAT), peroxides (POD), ascorbate peroxidase (APX) and glutathione reductase (GR) activities also elevated significantly under water stress (p < 0.01). Ascorbic acid (AsA), glutathione (GSH) and oxidized glutathione (GSSG) contents also showed a marked increase (p < 0.01). The main root treated with water showed the most positive impact on the 5th day. Water stress boosted the activities of key enzymes including 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR), farnesyl pyrophosphate synthase (FPS), squalene synthase (SS), squalene epoxidase (SE), and dammarenediol-II synthase (DS) involved in the ginsenoside biosynthesis pathway (p <0.01). This resulted in a significant an increase in the level of ginsenosides Rg1, Rb1, Rf, Rg2+Rh1, Rc, and Rb3, by 42.4%, 21.0%, 15.7%, 157.9%, 18.3%, and 10.6% respectively, and an increase of 40.1% in total saponins content. Similarly, the fibrous root changes in the treated sample showed the most positive impact on the 4th day. Specifically, Rg1, Re, Rb1, Rf, Rg2+Rh1, Rc, Ro, and Rb2 increased by 41.8%, 20.5%, 17.3%, 84.3%, 30.7%, 35.6%, 8.6%, and 7.6%, respectively, and an increase of 4.2% in total saponins content. Furthermore, 1,3-disphosphoglycerate (1,3-DPG) contents and phosphoenolpyruvate carboxylase (PEPC) activities, which are key intermediate of primary metabolism, were significantly elevated under water stress (p < 0.01). This indicates that the primary source of the raw materials used in the biosynthesis of secondary metabolites is sugars. Pharmacodynamic analysis demonstrated that water stress could increase the contents of ginsenosides, improve the quality of ginseng, and enhance the efficacy of ginseng root to a certain extent.
The Alberta Back Care Pathway: The feasibility of implementing a novel care pathway to improve low back pain management for family physicians in primary care
Authors: Powelske Brandyn , Kongsted Alice , Jones Allyson , Kawchuk Gregory
Published: November 2024

Background

Family physicians in Canada’s universal healthcare system often manage low back pain patients using interventions not recommended in clinical guidelines, such as pharmaceuticals, imaging and spinal injections, while guideline-based treatments like education and exercise remain unfunded. The Alberta Back Care pathway was developed to address this gap, offering funded, evidence-based care for low back pain patients in 5 streams (acute, sub-acute, chronic, chronic non-responsive and stable radiculopathy).

Objective

To evaluate the feasibility of implementing the pathway in two urban Primary Care Networks in Alberta, Canada.

Materials and methods

Each of the 5 pathway streams provided physicians with information scripts, no-cost interventions (pharmaceuticals and otherwise) and interventions to avoid. From April 2021 to November 2023, the RE-AIM framework was used to assess implementation feasibility of the pathway.

Results

For the RE-AIM dimension of reach, 25% (n = 41/162) of eligible family physicians in Primary Care Network “A” and 12% (n = 26/221) in Primary Care Network “B” enrolled in the study. Over half of enrolled physicians (n = 21/41 and 21/26) referred at least one patient with most referrals to the GLA:D Back program for chronic low back pain stream (93% in network “A” and 88% in network “B”). Implementation, evaluated as the proportion of referrals by physician compared to their total low back pain caseload, was low (> 0–10% referred) for 52% (n = 11/21) of physicians in network “A”, and medium-low (10–25% referred) for 52% (n = 11/21) of physicians in network “B”. The number of pathway-appropriate patients in each physician’s caseload was unknown. Maintenance at 12 months was 56% (n = 10/18) in network “A” and 39% (n = 7/18) in network “B”.

Conclusion

The Alberta Back Care pathway was feasible to implement during the pandemic and primarily serving patients with chronic low back pain by providing access to a guideline-based education and exercise group program (GLA:D Back).
Application of a sEMG hand motion recognition method based on variational mode decomposition and ReliefF algorithm in rehabilitation medicine
Authors: Yuan Yue
Published: November 2024

Hand motion intention recognition has been considered as one of the crucial research fields for prosthetic control and rehabilitation medicine. In recent years, surface electromyogram (sEMG) signals that directly reflect human motion information are ideal input sources for prosthetic control and rehabilitation. However, how to effectively extract components from sEMG signals containing abundant limb movement information to improve the accuracy of hand recognition still is a difficult problem. To achieve this goal, this paper proposes a novel hand motion recognition method based on variational mode decomposition (VMD) and ReliefF. First, VMD is used to decompose the sEMG signal into multiple variational mode functions (VMFs). To efficiently extract the intrinsic components of the sEMG, the recognition performance of different numbers of VMFs is evaluated. Then, four features representing hand motion intentions are extracted from the VMFs to form the initial feature space. Next, the ReliefF algorithm is used to remove redundant features from the feature space. In order to select a feature space that can effectively reflect the intention of hand movements, the hand movement recognition performance of 8 low-dimensional feature spaces is evaluated. Finally, three machine learning methods are used to recognize hand movements. The proposed method was tested on the sEMG for Basic Hand movements Data Set and achieved an average accuracy of 99.14%. Compared with existing research, the proposed method achieves better hand motion recognition performance, indicating the potential for healthcare and rehabilitation applications.
Applications of marine microbial community models in the nature-based economy
Authors: Robaina-Estévez Semidán , Gutiérrez Jay
Published: November 2024

Marine microorganisms are central to global ecological and biogeochemical systems, with their intricate interactions shaping community dynamics. While meta-omics data sets have revolutionized marine microbial ecology, they often provide fragmented insights, underscoring the need for advanced integrative modeling frameworks. In this review, we highlight the potential that community genome-scale metabolic models (cGEMs), in combination with meta-omics and environmental data sets, offer in advancing marine microbial ecology. We explore 3 key applications: quantifying marine ecosystem services, guiding bioremediation strategies for environmental challenges, and enhancing climate and biogeochemical models. Furthermore, we propose novel indices derived from cGEMs to assess microbial contributions to ecosystem functions, potentially informing economic valuation strategies for marine conservation. This interdisciplinary approach paves the way for innovative strategies in biotechnology, environmental restoration, and the development of nature-aligned economic systems, ultimately contributing to the preservation and sustainable use of marine ecosystems.

Az udmurt embernevek néhány elméleti kérdése
Authors: Kozmács István
Published: November 2024

The paper presents the Udmurt onomastic terminology on how the Udmurt people used their personal names (antroponyms) until the first half of the 20th century. It draws attention to the fact that the question of the naming of the Udmurt-speaking population can still be a challenge for researchers today. However, with the passage of time and the modernisation of life, it has become less and less possible to explore the problem of former personal names of the Udmurt people on the basis of contemporary ethnographic, texts collections and data. Perhaps the exploration of archival sources for the purpose of nomenclature can bring us closer to a solution.
Challenges to effective road user education in reducing road traffic accidents in Nigeria
Authors: Adenigbo Adedotun Joseph
Published: November 2024

The increasing trend in road traffic accidents (RTAs) has remained a concern that seems to defy solutions over the years. A major strategy for reducing RTAs is road user education, which uses campaigns and enlightenment programmes. However, the effectiveness of road user education in curtailing the trend of RTAs is faced with several challenges. This study examines the challenges to the effectiveness of road user education in reducing the trend of RTAs in Nigeria. The data for the study were collected with a well-designed questionnaire administered randomly to respondents. The questionnaire presented twelve (12) statements in a 5-point Likert scale for the respondents to rank in order of significance to identify the most significant challenges to road user education. The data collected were subjected to exploratory factor analysis to reduce the items to the most significant challenges facing effective road user education. The study identified institutional, participatory and funding as the most significant challenges confronting effective road user education in Nigeria. The study provides insight into the approach that can enhance the effectiveness of road user education by improving institutional policies, road user behaviour and external sources of funding.

Electroencephalogram-based time-frequency analysis for Alzheimer’s disease detection using machine learning
Authors: Daniel Rodrigues Sérgio , Miguel Rodrigues Pedro
Published: November 2024

Background: Alzheimer’s disease (AD) is the most common form of dementia. The lack of effective prevention or cure makes AD a significant concern, as it is a progressive disease with symptoms that worsen over time. Objective: The aim of this study is to develop an algorithm capable of differentiating between patients with early-stage AD (mild cognitive impairment [MCI]), moderate AD, and healthy controls (C) using electroencephalogram (EEG) signals. Methods: A publicly available EEG database was utilized, with seven EEG recordings selected from each study group (MCI, AD, and C) to ensure a balanced dataset. For each 1-s segment of EEG data, 43 time-frequency features were computed. These features were then compressed over time using 10 statistical measures. Subsequently, 15 classifiers were employed to distinguish between paired groups using a 7-fold cross-validation. Results: The strategy yielded better results than state-of-the-art methods, achieving a 100% accuracy in both C versus MCI and C versus AD binary classifications. This improvement translated to a 2% increase in accuracy for C versus MCI and a 4% increase for C versus AD, despite a 1.2% decrease in performance for AD versus MCI. In addition, the proposed method outperformed prior work on the same database by 4.8% for the AD versus MCI comparison. Conclusion: The present study highlights the potential of EEG as a promising tool for early AD diagnosis. Nevertheless, a more extensive database should be used to enhance the generalizability of the results in future work.
Obstáculos epistemológicos e didáticos identificados na compreensão de professores do ensino fundamental sobre probabilidade
Authors: Farias Vitória da Silva , Rufino Maria Aparecida da Silva , Silva José Roberto da
Published: November 2024

O ensino de Probabilidade apresenta várias lacunas, dentre elas, a má compreensão dos seus conceitos e a falta de formação no que diz respeito às estratégias didáticas que contemple suas aplicações em contextos reais. Muitas dessas lacunas podem ser investigadas à luz dos obstáculos de origem epistemológica estudados pelo filósofo Gaston Bachelard, que se referem a conhecimentos que, em certos contextos, mostraram-se satisfatórios, mas que em outros, representam entraves para o avanço do conhecimento científico. À vista disso, este artigo analisa os obstáculos existentes em relação à compreensão do conceito de probabilidade de um grupo de professores dos Anos Finais do Ensino Fundamental, de forma a reconhecer os elementos retardadores, caracterizar sua natureza epistemológica e identificar em que medida podem se configurar em obstáculos didáticos. Trata-se de um estudo de caso educacional envolvendo um grupo de dez professores licenciados em Matemática, cuja presença enraizada de concepções conservadoras da Matemática como ciência exata e determinística dificulta algumas compreensões, como, por exemplo, o estudo de fenômenos aleatórios em Probabilidade. No que se refere a classificação bachelardiana quanto a natureza epistemológica dos obstáculos, identificamos na pesquisa em pauta, a presença de obstáculos oriundos da experiência primeira, da generalização prematura, do conhecimento unitário e pragmático, e dos obstáculos verbais. Portanto, tais noções que se configuram em termos de obstáculos epistemológicos podem influenciar nas escolhas estratégicas do docente e, repercutir em possíveis erros dos alunos. Dessa forma, este estudo revela a importância de refletir sobre a abordagem da Probabilidade nos cursos de formação de professores, e, consequentemente, na Educação Básica, com o intuito de sanar dificuldades que perduram por anos e que levam a erros de compreensão.

Authors: Ortiz Ibáñez Erick Rodolfo , Adúriz-Bravo Agustín , Tuay Sigua Rosa Nidia
Published: November 2024

El pensamiento crítico (PC) ha sido objeto de indagación amplia y constante en diferentes ramas del conocimiento; de esta manera, deviene en un pilar de la investigación en la formación de ciudadanía crítica. En este sentido, el pensamiento crítico ha sido incluido como un constructo central en el ámbito educativo y esto es particularmente cierto para el caso de la Enseñanza de las Ciencias (EC). En el presente artículo se examina el uso de tal constructo en publicaciones de didáctica de las ciencias para el nivel educativo de Secundaria, durante el periodo comprendido entre 2012 y 2024, mediante una revisión documental realizada en las bases de datos Scopus y Google Académico. Se recogió una muestra de 8226 documentos de donde, mediante la declaración PRISMA, se revisaron 2235 que relacionaban el pensamiento crítico en la enseñanza de las ciencias. Finalmente, se seleccionan 58 que priorizan los criterios del pensamiento crítico en la enseñanza de las ciencias en la Educación Secundaria, análisis que constituye la necesidad de profundizar en la construcción del pensamiento crítico en el contexto de la enseñanza de las ciencias, y de reflexionar sobre la importancia que se le atribuye en las aulas de ciencias. Esta revisión forma parte de la estructura investigativa de la tesis doctoral que se desarrolla en la Universidad Pedagógica Nacional de Colombia, en el grupo de investigación Educación en Ciencias, Ambiente y Diversidad (EduCADiverso).

This novel case documents the successful use of transcatheter aortic valve implantation to treat severe aortic insufficiency arising from aortic root dissection following the repair of an ascending aortic aneurysm in a 75-year-old female patient. After she presented with symptoms of congestive heart failure, investigation revealed new severe aortic insufficiency and an acute aortic dissection. Given the prohibitive risks of reoperation, a self-expanding 27-mm Portico (St Jude Medical) prosthetic aortic valve was deployed, resulting in substantial clinical improvement without procedural complications. This case highlights the versatility of transcatheter aortic valve implantation in managing complex aortic disease and emphasizes the critical role of multidisciplinary evaluation and careful prosthesis selection.
Understanding The Drivers and Barriers Towards Sustainable Consumption: An Approach by Linking a Pedagogical Strategy of Active Learning with Adopting Sustainable Behaviors by Students
Authors: Arias Claudia
Published: November 2024

Adopting sustainable consumption behaviors is imperative for achieving better sustainable production and consumption patterns (SDG12). Individuals play a crucial role in this goal as both part of the problem and the solution. Consequently, various actors aim to address the factors influencing individuals' adoption of these behaviors. Among these actors, higher education institutions play a unique role due to their opportunity to guide future generations through Education for Sustainable Consumption (ESC) towards sustainable values, attitudes, competencies, and behaviors. Understanding the drivers and barriers individuals face toward sustainable consumption is crucial for actively pursuing sustainability. However, few efforts have addressed this problem based on the actual experiences of individuals, and even fewer have focused on students as individuals who will hopefully lead organizations with a sustainability mindset. This research aims to fill this gap by linking a pedagogical strategy of active learning to the adoption of sustainable behaviors. Using a qualitative approach, we analyzed the experiences that students reported over three academic semesters in an online forum. The findings reveal that barriers to adopting sustainable behaviors are mostly contextual, while internal factors motivate people to advance toward this type of practice. From this methodological approach, emergent factors provide insights that could guide future policies and strategies to achieve better sustainable consumption patterns.
The Javeriana Cali’ Strategic Plan for the Sustainable Management: An Example of How to Implement, Disseminate and Evaluate Sustainability Policies
Authors: Tello Isabella , Aguilar Jose Alejandro
Published: November 2024

In order to organize the multiple actions the Universidad Javeriana had been developing for the sustainable management of its campus, a strategic plan was structured. The plan is structured in five major programs: water resources, energy, biodiversity, recycling and reduction of CO2 emissions. For the definition of these five programs we were inspired by the contributions of the thematic structure of Green Metrics, the recommendations of the Encyclical Laudato Si and the SDGs. In turn, each program is broken down into sub-programs, projects and sub-projects. Each program also includes cross-cutting strategies articulated in sub-programs which are broken down into research projects, semester projects, graduate work and theses. Also, sub-programs for disseminating initiatives and entrepreneurship are considered. The planning instrument is taken to the detail of operational planning, using the Gantt Chart. A team coordinates the coordination of the different programs and meets weekly to review its progress. The plan was presented and approved to the University's Steering Committee, and the document has been incorporated into the University's Strategic Plan. It is also being used to link professors from civil engineering, electronics and architecture careers who invite students to carry out semester or degree work on topics that strengthen campus execution.

The university campuses are like microcities, providing employees and students with social opportunities and essential services in addition to their core educational activities (teaching, research, and outreach). The smart campus is a growing trend that makes efficient use of infrastructure by integrating smart technologies for decision-making and advancing sustainability goals. The mobility and transport project at the Unicamp University campus is part of the Smart Campus Management Technical Chamber, and the Campus 5.0 concept is aligned with several sustainable development goals outlined in the UN's 2030 Agenda. This proposal aims to develop an inventory of vehicle emissions, establish the connectivity of the information and communication network to analyze the impacts of vehicles on local air quality, and structure support models for decision-making, in addition to presenting practical solutions implemented at Unicamp aiming at greater sustainability of the campus. The information and communication network will allow the collection and analysis of data in real time, providing accurate and updated information on vehicle emissions and air quality in the campus area. Decision support models will be developed, which will allow the definition of policies and actions to promote sustainable mobility on campus, contributing to the creation of a healthier and more sustainable university environment. These results will aid university administrators in improving Green Metrics' key performance indicators.
Using Direct Decarbonization Strategies to Plan for a Resilient and Fossil Fuel-Free Future
Authors: O'Day Kelli , Fresquez Carla
Published: November 2024

UC Davis has a vision for a fossil fuel-free future. The university released the Fossil Fuel-Free Pathway Plan (FFFPP) to address the climate crisis by reducing Scope 1 and Scope 2 greenhouse gas emissions. The FFFPP outlines strategies to eliminate 95% of fossil fuel use, based on 2019 levels, from university operations by 2040. The plan includes the Davis campus, UC Davis Health, Aggie Square, Tahoe Environmental Research Center, Bodega Marine Laboratory, and multiple outlying and leased properties. UC Davis has already broken ground on the Big Shift, a fossil fuel-free conversion project that will allow the campus to heat buildings with electricity rather than natural gas and reduce the Davis campus’s fossil fuel consumption by 80%. The FFFPP aligns with broader climate goals and initiatives set by the University of California (UC). The Pathways to a Fossil-Free UC Task Force was created to investigate the challenge of accelerating efforts to decarbonize each UC campus. To further support these efforts the UC recently adopted stronger climate action goals that prioritize direct emission reductions. UC Davis participates in the UC President’s Bonnie Reiss Leading on Climate Student Fellowship Program, which funds student-generated projects that reinforce the UC-wide climate action goals. UC Davis students in the program are playing an important role in climate resiliency on campus.

This study focuses on the "Setting and Infrastructure" indicator of the UI GreenMetric World University Rankings, exploring the case of the Universidad Católica de Córdoba (UCC). In an environment where sustainability becomes a transversal axis for university management, the UCC has implemented an environmental conservation strategy of natural resources and management of sustainable infrastructure, demonstrating a firm commitment to caring for the world we live in. Combining the estimation of the institutional carbon footprint, the conservation of the native forest, the promotion of safe, sustainable and accessible infrastructures, and the care of human health, the UCC moves towards sustainability from a comprehensive approach. Its projects linked to environmental care seek a triple impact: 1) Environmental, through the displacement of carbon dioxide (CO2). 2) Academic, instances of training, awareness and research. 3) Social, activities, projects or programs linked to University Social Responsibility. This approach aligns with the spirit of the Encyclical Letter Laudato Si', emphasizing the interconnection between human and social dimensions and environmental conservation. This model involves combining the significant capture of CO2 from our native forest, the execution of the clean energy infrastructure project with low CO2 emissions to mitigate up to 70% of the environmental impact of our carbon footprint. This study contributes to the global dialogue on sustainable practices in the university environment, proposing a replicable framework for other institutions committed to sustainability.

Published: November 2024

This paper examines the attitudes, opinions, and values that consumers hold regarding environmentally friendly products in the domestic market. Given the fact that consumers have been focused on sustainability and environmental consciousness more than ever, it is crucial to understand how these factors influence purchasing decisions. Special attention will be paid to the role of environmental awareness in shaping consumer attitudes and behaviors in the context of purchasing sustainable products. To collect quantitative data, a structured questionnaire will be used, while focus groups will be applied as a qualitative method to gain deeper insights into consumer attitudes and opinions. Additional data will be collected through observational studies in stores and online shopping. The research results will provide data for more precise definition of marketing strategies, adjustment of production processes to produce more environmentally friendly products, as well as for product development.

Conventional ways of delivering sustainability content often fail to capture the breadth and dynamism of university challenges. To overcome the issue, UI GreenMetric has proposed a new way of delivering content by using digital media. This study investigates the integration of digital mediaincluding Instagram, YouTube, Facebook, and Website to augment sustainability insights within the UI GreenMetric World University Rankings Network. This study analyzes the results, effects, and further implications of UI GreenMetric’s practices in incorporating user-generated content from those digital media platforms into the sustainability assessment framework to leverage the ubiquity and the richness of the content. The analysis is conducted for various activities, such as podcast/live discussions, event streaming, posts and videos related to sustainability initiatives. The findings show that integrating digital media has significantly boosted sustainability outreach within the UI GreenMetric network. UI GreenMetric not only drives the transformation of individuals, communities, and universities toward sustainability but also extends its impact through dozens of online events, such as webinars, workshops, courses, live discussions, and podcasts throughout the year. These efforts have successfully reached a wider audience, leading to meaningful behavioral changes as participants engage in campaigns and actively contribute to rankings and events.
Prefigované tvary sloves anglického původu v jazyce mladé generace
Authors: Svobodová Diana , Sekerová Kamila , Entlová Gabriela
Published: November 2024

Text se zabývá analýzou aktuálního výskytu a způsobů užívání prefigovaných sloves tvořených od základů slov přejatých z angličtiny v komunikaci příslušníků mladé generace. Celkem 441 prefixálních derivátů utvořených od 125 slovesných základů, rozlišených na základě míry grafické adaptace, je v textu rozděleno jak dle zařazení do slovesných tříd na základě kmenotvorných sufixů, tak především podle užitých prefixů domácích i přejatých. K jednotlivým prefigovaným tvarům jsou vedle jejich morfologicko-sémantické charakteristiky připojeny odpovídající české ekvivalenty a příklady užití a diskutována je zejména variantnost prefixů a významové modifikace jimi tvořených sloves.
K problematice bohemismů v náboženské terminologii
Authors: Aleksiayevich Hanna
Published: November 2024

Příspěvek je věnován zkoumání vlivu češtiny na náboženskou terminologii polštiny, slovenštiny, horní a dolní lužičtiny, polabštiny, běloruštiny, ukrajinštiny a ruštiny od počátku jejich písemnictví do 17. stol. Byla provedena historicko-etymologická analýza 82 potenciálních bohemismů, jež byly rozděleny podle svého původu do pěti skupin (A, B, C, D, E). Za bohemismy lze uznat 50 slov, která byla přejata z češtiny do západoslovanských a východoslovanských jazyků jak přímo, tak i nepřímo. Podařilo se vysvětlit geografii pronikání bohemismů do jiných slovanských jazyků a rozsah jejich přejímání.
Tělesné metafory v české lokalizaci prostoru: analýza lokačních orientátorů čerpaných z domény lidského těla
Authors: Škodová Svatava
Published: November 2024

Výrazy vyjadřující prostor v jazyce často používáme automaticky, aniž bychom přemýšleli o jejich základech a souvztažnostech. Vhodný rámec pro jejich zkoumání poskytuje kognitivní lingvistika prostřednictvím metaforických modelů odvozených ze zkušenosti lidského těla pohybujícího se v prostoru. Předkládaný text, zasazený teoreticky do Levinsonových subdomén prostorového jazyka, se zaměřuje na intrinsní rámce vyjadřování prostoru v češtině. Pro vyjadřování umístění objektů v prostoru využívá čeština převážně relativní systém vycházející z perspektivy po zorovatele, zřídka využívá absolutní systém orientovaný podle světových stran. Tato studie analyzuje intrinsní systém prostorových lokalizátorů v češtině, analýza se zaměřuje pouze na lokalizátory pocházející ze zdrojové domény lidského, ale částečně i zvířecího těla, odhalujíc metonymie, kde části těla slouží jako ukazatele prostorových vztahů.

Published: November 2024

With the global attention on plastic pollution, polylactic acid (PLA) is quickly becoming an alternative to traditional plastics. The current pressing challenge now is to enhance the degradation rate of PLA while simultaneously reducing costs. We investigated the influence of reed fibers on the biodegradation of PLA-based composites under various environmental conditions. The crystallization behavior, surface morphology, and functional group changes of the samples during enzymatic degradation were analyzed using differential scanning calorimetry (DSC), scanning electron microscopy (SEM), and Fourier transform infrared spectrometer (FTIR). The results indicate that reed fibers significantly increased the hydrophilicity of the composites and reduced the crystallinity of PLA, thereby enhancing the degradation rate of the composites. This rate increased with the higher concentration of reed fibers. The research results will provide a theoretical reference for the design of PLA composites that are better aligned with market demand, which is used to balance the requirements for degradation performance during product use and after disposal and expand the application of PLA/RF composites in the construction, agriculture, and packaging.
