Emerging technologies in citizen science and potential for insect monitoring.

Emerging technologies are increasingly employed in environmental citizen science projects. This integration offers benefits and opportunities for scientists and participants alike. Citizen science can support large-scale, long-term monitoring of species occurrences, behaviour and interactions. At the same time, technologies can foster participant engagement, regardless of pre-existing taxonomic expertise or experience, and permit new types of data to be collected. Yet, technologies may also create challenges by potentially increasing financial costs, necessitating technological expertise or demanding training of participants. Technology could also reduce people's direct involvement and engagement with nature. In this perspective, we discuss how current technologies have spurred an increase in citizen science projects and how the implementation of emerging technologies in citizen science may enhance scientific impact and public engagement. We show how technology can act as (i) a facilitator of current citizen science and monitoring efforts, (ii) an enabler of new research opportunities, and (iii) a transformer of science, policy and public participation, but could also become (iv) an inhibitor of participation, equity and scientific rigour. Technology is developing fast and promises to provide many exciting opportunities for citizen science and insect monitoring, but while we seize these opportunities, we must remain vigilant against potential risks. This article is part of the theme issue 'Towards a toolkit for global insect biodiversity monitoring'.

Collaborative science in action: A 20 year perspective from the Health and Environmental Sciences Institute (HESI) cardiac safety committee.

The Health and Environmental Sciences Institute (HESI) is a nonprofit organization dedicated to resolving global health challenges through collaborative scientific efforts across academia, regulatory authorities and the private sector. Collaborative science across non-clinical disciplines offers an important keystone to accelerate the development of safer and more effective medicines. HESI works to address complex challenges by leveraging diverse subject-matter expertise across sectors offering access to resources, data and shared knowledge. In 2008, the HESI Cardiac Safety Technical Committee (CSTC) was established to improve public health by reducing unanticipated cardiovascular (CV)-related adverse effects from pharmaceuticals or chemicals. The committee continues to significantly impact the field of CV safety by bringing together experts from across sectors to address challenges of detecting and predicting adverse cardiac outcomes. Committee members have collaborated on the organization, management and publication of prospective studies, retrospective analyses, workshops, and symposia resulting in 38 peer reviewed manuscripts. Without this collaboration these manuscripts would not have been published. Through their work, the CSTC is actively addressing challenges and opportunities in detecting potential cardiac failure modes using in vivo, in vitro and in silico models, with the aim of facilitating drug development and improving study design. By examining past successes and future prospects of the CSTC, this manuscript sheds light on how the consortium's multifaceted approach not only addresses current challenges in detecting potential cardiac failure modes but also paves the way for enhanced drug development and study design methodologies. Further, exploring future opportunities and challenges will focus on improving the translational predictability of nonclinical evaluations and reducing reliance on animal research in CV safety assessments.

Novel high-pressure/high-temperature reactor cell for in situ and operando x-ray absorption spectroscopy studies of heterogeneous catalysts at synchrotron facilities.

This paper presents the development of a novel high-pressure/high-temperature reactor cell dedicated to the characterization of catalysts using synchrotron x-ray absorption spectroscopy under operando conditions. The design of the vitreous carbon reactor allows its use as a plug-flow reactor, monitoring catalyst samples in a powder form with a continuous gas flow at high-temperature (up to 1000 °C) and under high pressure (up to 1000bar) conditions, depending on the gas environment. The high-pressure/high-temperature reactor cell incorporates an automated gas distribution system and offers the capability to operate in both transmission and fluorescence detection modes. The operando x-ray absorption spectroscopy results obtained on a bimetallic InCo catalyst during CO2 hydrogenation reaction at 300 °C and 50bar are presented, replicating the conditions of a conventional microreactor. The complete setup is available for users and permanently installed on the Collaborating Research Groups French Absorption spectroscopy beamline in Material and Environmental (CRG-FAME) sciences and French Absorption spectroscopy beamline in Material and Environmental sciences at ultra-high dilution (FAME-UHD) beamlines (BM30 and BM16) at the European Synchrotron Radiation Facility in Grenoble, France.

Environmental scientists’ support for public engagement strategy development is predicted by a range of factors, but mostly perceived benefits

ABSTRACT Communication strategies define audience-specific behavioral goals, identify priority cognitive and affective communication objectives necessary to achieving those goals, and propose specific communication tactics meant to increase the likelihood of achieving those objectives. Unfortunately, it appears that few scientific organizations have concrete, evidence-based strategies. This study therefore uses survey data to explore environmental scientists’ willingness to prioritize the behavioral goal of creating a shared public engagement strategy. It finds that the best predictor of prioritizing strategy development is the perceived benefits of having a strategy. The perceived feasibility of developing a strategy given available resources, and trust in their engagement staff were also reasonable predictors of strategy prioritization. Early career respondents and those who said they had previously thought about developing an engagement strategy were also more likely to say they think developing an engagement strategy should be prioritized. The study builds on the strategic communication as planned behavior approach to try to better understand scientists’ communication choices in a way that could support efforts to improve these choices.

Can Citizens Do Science? Science in Common and Social Responsibility

Citizen science is an effective tool that unites ordinary citizens and scientists for a common cause. In particular, this tool enables ordinary citizens to participate in research and increases the likelihood of generating new knowledge. It is seen as the democratization of science. It is mainly applied in developed countries, and citizens usually help obtain environmental data with emerging technologies. However, training citizens to obtain good-quality data is one of the most significant challenges. It is also important to involve citizens in other phases, such as data analysis, discussion, and knowledge generation. Citizen science can be a tool for integrating different groups in science to promote social inclusion, including environmental, agricultural, earth, and life sciences. Thus, citizen science can contribute to education, sustainability, and climate change mitigation.

An industry review of recent graduate employee’s performance compared to workplace expectations: An environmental science case study

This study developed and tested a model of higher education environmental science program review through industry-wide surveys of environmental science graduate employers. We surveyed 62 environmental professionals who manage recent environmental science graduate employees in eastern Australia. The survey captured expectations of graduates’ skill performance compared to workplace expectations in the first 6 months of employment in both degree-specific skills and general employment skills. Graduate employee skill importance was ranked significantly higher than their actual performance in degree-specific skills including field work, formal correspondence, policy development, data analysis/interpretation, and understanding environmental legislation. Performance was also significantly lower than expectations of generic employment skills including foundation, collaborative, and employability skills. Work placement within undergraduate programs was reported as being pivotal in efficiently preparing graduates, although workplace time limitations hinder participation. This study provides new evidence for universities to adopt work placement or other work integrated learning as a core program component, embed skill awareness and skill portfolio development in curricula, and periodically undertake industry review of graduate employee performance compared to workplace expectations. The new model presented here, of higher education program review, incorporating both graduate employee performance and employer expectations, will assist universities continuing relevancy in a dynamic employment market.

Trends in Science Humanities Convergence Education in Japanese Universities and their Implications

As science and technology advance, fundamental changes are taking place in individual lives and society. At this time, the dichotomous thinking that excessively distinguishes between science and humanities, as is prevalent in Korea and Japan, hinders the nurturing of the next generation’s capabilities. Since the 21st century, the Japanese government has continued to promote transversal and/or convergence education in science and humanities to overcome the limitations of early specialization in secondary education and the resulting limitations in college education. With the help of government financial and policy support, Japanese universities offer transversal education in a variety of ways, such as degree programs in interdisciplinary fields such as environmental studies and data science, a problem-solving-oriented curriculum, the activation of double major and minor systems, and bachelor degree programs in the liberal arts. Also, a trend began to redefine education goals to fit its nature and strengthen the liberal arts and sciences. This article explores the background and process of promoting transversal education through the Japanese government's official documents and articles, showing that it is being carried out within the larger framework of the pursuit of liberal arts in the 21<sup>st</sup> century. Lastly, this study shows that these trends fit into the context of liberal education and demonstrates how this field is reemerging globally.

Carbon-polymer composites for environmental applications

Abstract Carbon polymer nanocomposite is a type of composite material that combines carbon-based materials with polymers and nanoparticles to achieve enhanced properties. These materials are designed to take advantage of the unique properties of each constituent to create a new material with superior performance compared to individual components. Nanocomposites composed of carbon-based polymers are the wonder and novel materials of contemporary research. At the forefront of a more recent scientific revolution, both material science and composite science are involved. Polymer science and nanotechnology are inextricably linked in today’s modern science. The subjects of environmental engineering science and nanotechnology require focused attention since these professions currently offer limited solutions for the increasingly pressing problems of groundwater contaminated with heavy metal and drinking water purification. Carbon polymer composites play a significant role in numerous modern applications due to their excellent electrical, mechanical, chemical, and thermal capabilities. Carbon polymer composites are viewed as desirable candidates for the manufacture of nanocomposite materials due to their nanoscale geometries, high aspect ratio, and specific surface area. Due to the shape-dependent nature of their physical and chemical characteristics as well as their thickness, carbon polymer nanocomposites have demonstrated excellent catalytic activity in organic chemical processes. It has been discovered that the catalytic product from the usage of carbon polymer nanocomposites is of tremendous utility in a variety of sectors, inclusive of material sciences, medicinal, and nutritional for biotechnology. As a result, the demand for carbon nanocomposites has grown quickly and the creation of new preparation techniques elevates a higher level of interaction.

ВПРОВАДЖЕННЯ ТЕХНОЛОГІЇ МІКРОНАВЧАННЯ СТУДЕНТІВ-ЕКОНОМІСТІВ ЗА ДОПОМОГОЮ ОНЛАЙН-КУРСІВ

After the outbreak of the pandemic in 2019 and the outbreak of war in the country in 2022, educational institutions at different levels of Ukraine switched to a mixed format of the educational process and were forced to look for modern approaches and technologies for organizing the education of students. This study examines the implementation of microlearning technology using online courses developed on the Moodle platform. Microlearning is a modern learning technology that involves short, intensive training modules focused on the development of specific theoretical knowledge and practical skills. Available online courses, which provide the ability to create and deliver different types of educational content, focus mainly on the formation of necessary knowledge and skills of students, but do not take into account their individual needs and interests in the learning process, and pay little attention to their satisfaction with education in modern conditions. This article investigates the impact of microlearning technology using online courses on students' satisfaction with learning. To determine the level of student satisfaction, an online survey was conducted among 61 students enrolled in the specialty 051 "Economics" programs, which include Business Economics, International Economics, Economic Cybernetics, and Digital Economy, at the National University of Life and Environmental Sciences of Ukraine. All these students were studying using microlearning technology with the use of online courses. As a result, that the level of student satisfaction with learning using this technology is most influenced by such factors as the availability of learning resources, consideration of individual abilities and needs in the online course, opportunities for interaction and communication with the teacher, as well as the format of learning materials and acquired knowledge. Accordingly, these factors should be taken into account when developing online courses and implementing microlearning technologies in the educational process.

ВИКОРИСТАННЯ ЗАСОБІВ ШТУЧНОГО ІНТЕЛЕКТУ ДЛЯ ПІДТРИМКИ ГРУПОВОЇ ДИНАМІКИ ПРОЄКТНИХ КОМАНД: ВПЛИВ НА САМОЕФЕКТИВНІСТЬ ТА ЗАЛУЧЕНІСТЬ СТУДЕНТІВ

The issue of maintaining group dynamics in flexible remote teams is currently in the focal point of attention not only of commercial companies and government agencies as a response to the changing conditions of work organisation, including those associated with the effects of the COVID-19 pandemic, but also of higher education institutions that train future professionals. Since intragroup dynamics is a key factor affecting team performance, this paper is the result of the study conducted as part of the Group Dynamics and Communications course at National University of Life and Environmental Sciences of Ukraine (NULES) to determine the potential of using AI tools as tools to support the group dynamics of self-organised teams during the implementation of educational projects. Based on the results of the free choice of project and team management tools, we categorised three groups among the 56 participants of the experiment according to the use or non-use of AI tools to enhance group dynamics, followed by self-assessment of the effectiveness of the selected tools in increasing their levels of self-efficacy and social engagement. The survey was based on a Likert scale measurement, and non-parametric methods of analysis and statistical hypothesis testing were used to process the results. The self-assessment confirmed that the incorporation of AI tools in the implementation of a team-based learning project did not influence the improvement of students' social engagement and the dynamics of self-efficacy for both effective and ineffective students. The authors identified the positive impact of using AI tools on its development for students with the average level of self-efficacy. We also presented an example of the use of Notion AI for enhancing group dynamics at each stage of team development according to B. Tuckman. The authors suggest that the impact of using AI tools in the process of implementing a group learning project depends more on personal characteristics of team members than on the choice of a specific AI model. Determination of application specifics of individual AI tools in the process of training future specialists in the implementation of various types of educational activities, particularly ethical considerations is recognised as an area for further research.

Bibliometric Analysis of Research Progress and Trends on Carbon Emission Responsibility Accounting

The severity of global climate change is a pressing issue, and carbon emission reduction requires collaboration between producers and consumers. Carbon emission responsibility accounting is critical for distributing the tasks associated with carbon reduction. To examine the current research status and future development trends of carbon emission responsibility accounting, we used the scientific quantitative knowledge graph method and CiteSpace software. We analyzed the data from 4089 studies retrieved from the Web of Science and China National Knowledge Infrastructure databases, focusing on various aspects such as the number of published papers, subjects, research focuses, research content, and future research directions. In 2022, the number of publications was 657. The largest number of published carbon emission responsibility accounting documents was published by scholars from China: there were 708 published articles, 35% of the 2002 articles published in the Web of Science. The reason may be that China, as a developing country, produces more carbon emissions. In order to actively shoulder international responsibilities and slow down global warming, China strengthened its research on carbon emission responsibility, the basic work on carbon emission reduction. This was followed by the United States and England. England showed high levels of research collaboration. “Environmental science” was one of the main subjects in the Web of Science database, representing 43.96% of total publications. Research focuses included input–output analyses and implied carbon export trade. This study summarizes the literature on carbon emission responsibility accounting in terms of research perspectives, accounting principles, and accounting methods. In the future, the accounting of carbon emission responsibility at the city level considering the carbon emission responsibility sharing method including three or more shared parties and accounting for the carbon emission responsibility between the upstream and downstream from the perspective of the industrial chain can be studied. The findings of this study provide guidance to researchers and policymakers for the progression and enhancement of carbon emission responsibility accounting.

Frontier Revitalisation of Industrial Heritage with Urban–Rural Fringe in China

The urban–rural fringe is at the forefront of the confrontation between the agricultural and industrial civilisations. How to handle the relationship between the two civilisations in this region and ensure its sustainable development is an eternal topic in the science of the human-living environment. Thanks to the special historical background of the Third Line construction, China’s industrial heritage connects with the urban–rural fringe that surpasses other countries. For the first time, this study connects China’s Third Line construction, industrial heritage, and urban–rural integration within the same context, combining big data bibliometric methods to obtain the development characteristics and context of China’s industrial heritage research starting from 2004. It has strong policy characteristics, is influenced by administrative orders, and is aligned with urbanisation efforts. Theoretical exploration is the first step in research, followed by value connotations and cultural qualities. It addresses various topics, including industrial heritage conservation, regeneration approaches, and cultural heritage tourism. The research focuses primarily on the value appraisal of industrial heritage, exploring revitalisation tactics and routes, as well as regional development models in urban–rural periphery areas. This study also examines how scholars generally consider the impact of industrial heritage on the economic, social, and cultural development of urban–rural fringe areas in order to integrate and propose various protection and utilisation strategies, such as industrial heritage preservation, cultural and creative industry development, and tourism resource development.

A tentative list of reptilian fauna of Algeria and their conservation status

Algeria is situated at the crossroads between Europe and Africa. The northern part of the country is listed as an area of high biodiversity. Currently, the ecosystems (rivers, lakes, deserts, forests etc.) and the species are under more pressure than ever. The impact of humans is significant and many factors constitute a strong threat to this fauna, especially reptiles, which are the most vulnerable because of their low mobility. Thus, pollution, the drying up of wetlands and their conversion to agriculture have clearly affected the existence of many species. The herpetofauna of Algeria is one of the most diversified in the Mediterranean Basin, consisting of 104 species of which 16.98% are endemic. We suppose that the present list of reptilian fauna provided in this paper is not exhaustive and it is expected to include more species given the lack of research on reptiles in Algeria and its large area. Our dataset contains information on reptile occurrences in Algeria. The dataset is based on original research by the staff of the Laboratory of Environmental Sciences and Agroecology of Chadli Bendjedid University in Algeria. The conservation status of all recorded species is given.

Evolution Characteristics and Influencing Factors of City Networks in China: A Case Study of Cross-Regional Automobile Enterprises

The optimization of the spatial structure of the city network is conducive to the scientific spatial distribution of industries and the promotion of coordinated regional development. This study selected the top 100 automobile enterprises in the Chinese stock market that belong to China’s pillar industry, a total of 1455 headquarters and branches, to establish an enterprise matrix. Based on the ownership linkage model, the evolution characteristics of city networks in China from 2000 to 2020 are revealed, and the influential factors of city networks are discussed using the negative binomial regression model. The findings are as follows: (1) there are significant differences in the status of automobile cities, forming a “pyramid network” hierarchy. (2) The agglomeration area of automobile cities has formed the development region of “4 + 4 + 1”. (3) The city network with hierarchical connections has formed a spatial structure of a “cross–cobweb” in the middle and “trapezoid–diamond” in the periphery. (4) Urban transportation conditions, the scientific research environment, the enterprise agglomeration economy, GDP per capita, and technological proximity positively impact the formation of a city network, but the total export–import volume has a negative impact. Overall, the government can use this study’s results to formulate policies for the automotive industry and urban development.

The split ladder of participation: A literature review and dynamic path forward

Participation of people in decision making and tackling complex problems where there is lack of consensus on the science and relevant values continues to be an important research topic. The 2015 Split Ladder of Participation offered a diagnostic and methodological framework cited in 162 papers. This paper addresses the question: What does a literature review of the Split Ladder of Participation reveal about engaging people in policy problems, effecting transformational change, and how can this diagnostic and strategic tool be improved? A systematic literature review revealed papers that disclose transformational change, or triple loop learning requires: strong social science; social and natural interdisciplinary science; and considerations of uncertainty in environmental science together with uncertainty of values and considerations of power. Policy problems with low levels of trust offer opportunities to engage interest and participation in their resolution. Governments over-utilizing methods limiting participation, may lead to lock-in. Focusing on complex, interconnected problems through participation creates an enduring policy and science, interdisciplinary innovation space. Recognizing participation that is plural, amorphous, and fluid draws attention to power, multiple stakeholder framings of complex issues, advances social learning changing values, norms, power, and the very ethics of science (where social and natural/physical scientists acknowledge and share their power with people), and ultimately advances environmental justice.

Analysis of Binding Modes between Three Perfluorosulfonates and GPER Based on Computational Simulation and Multiple Spectral Methods

Perfluorinated compounds (PFCs) belong to a significant category of global environmental pollutants. Investigating the toxicological effects of PFCs within biological systems is of critical significance in various disciplines such as life sciences, environmental science, chemistry, and ecotoxicology. In this study, under simulated human physiological conditions (pH = 7.4), a combination of multiple spectroscopic techniques and computational simulations was employed to investigate the impact of perfluorinated compounds (PFCs) on the G protein-coupled estrogen receptor (GPER). Additionally, the research focused on exploring the binding modes and toxicological mechanisms between PFCs and GPER at the molecular level. All three perfluorinated sulfonic acids (PFSAs) can induce quenching of GPER fluorescence through static quenching and non-radiative energy transfer. Steady-state fluorescence calculations at different temperatures revealed apparent binding constants in the order of 106, confirming a strong binding affinity between the three PFSAs and GPER. Molecular docking studies indicated that the binding sites of PFSAs are located within the largest hydrophobic cavity in the head region of GPER, where they can engage in hydrogen bonding and hydrophobic interactions with amino acid residues within the cavity. Fourier transform infrared spectroscopy, three-dimensional fluorescence, and molecular dynamics simulations collectively indicate that proteins become more stable upon binding with small molecules. There is an overall increase in hydrophobicity, and alterations in the secondary structure of the protein are observed. This study deepens the comprehension of the effects of PFCs on the endocrine system, aiding in evaluating their potential impact on human health. It provides a basis for policy-making and environmental management while also offering insights for developing new pollution monitoring methods and drug therapies.

Exploring low-dose gamma radiation effects on monoterpene biosynthesis in Thymus vulgaris: insights into plant defense mechanisms.

Thymus vulgaris, commonly known as thyme, is a plant renowned for producing monoterpenes. This study aimed to understand the effects of low-dose gamma radiation, specifically in the range of 1-5Gy, on various traits of Thymus vulgaris, providing context on its importance in agricultural and medicinal applications. The research explored morpho-physiological, biochemical, and gene-expression responses in thyme plants under no gamma- and gamma-ray exposure conditions. The study revealed complex relationships between gamma-ray doses and plant characteristics. In particular, shoot and root lengths initially increased with low doses (1-3Gy) but decreased at higher doses (5Gy), suggesting a dose-dependent threshold effect. Similarly, shoot and root fresh weights displayed an initial increase followed by a decline with increasing doses. Biochemical parameters showed dose-dependent responses, with low to moderate doses (1-3Gy) stimulating enzyme activities and high doses (5Gy) inhibiting them. Gene expression analysis was focused on the following specific genes: thymol synthase, γ-terpinene synthase, and carvacrol synthase. Low to moderate doses increased the expression of these genes, resulting in increased production of bioactive compounds. However, higher doses had diminished effects or suppressed gene expression. Metabolite analysis demonstrated dose-dependent responses, with moderate doses enhancing secondary metabolite production, while higher doses provided limited benefits. These findings underscore the implications of using gamma radiation to enhance secondary metabolite production in plants and its potential applications in agriculture, medicine, and environmental science. The study emphasizes the potential of gamma radiation as an external stressor to influence plant responses and highlights the importance of understanding such effects in various fields.

Evolution of hotspots and research trends in agricultural mulch film research: a bibliometric review

Agricultural mulch film (AMF) can increase the soil temperature, reduce the evaporation of water and soil erosion, control the number of weeds and pests, and improve the yield and quality of crops. However, the environmental pollution caused by AMF residues is becoming serious and has attracted increasing amounts of research. Research on AMF is a complex subject with diverse content and rich perspectives. Currently, there have been few systematic reviews of the use of AMF. To comprehensively and deeply understand the current status, hotspots, and trends of research on AMF, this paper conducted a bibliometric analysis of AMF literature from 1960 to 2022. Results are as follows: the overall publication volume in the field of AMF has increased 1960 to 2022. The top three countries contributing to publication volume include China, United States (US) and India, which are also the main collaborating nations. Notably, cooperation between China and US is the most frequent, and a cluster constituted by European nations serve as a primary collaborator for other countries. Owing to the introduction and development of the concept of degradable plastics, the field entered a period of rapid growth after 1970 and has primarily focused on continuous development in the areas of horticulture and environmental science. Current research on AMF primarily aims to: 1) develop applications that are aimed at enhancing the yield and quality of crops, and 2) improve the materials used to produce AMF to reduce its environmental impact. The persistent hotspots of research in AMF revolve around modifying the soil microclimate, promoting crop growth and development, and increasing crop yields. Frontier AMF research includes: exploring crop quality enhancement mechanisms, developing low-cost biodegradable film technologies and their natural degradation effects, and investigating AMF’s impact on soil nitrous oxide emissions and associated mechanisms.

Analysis of the adsorption and fixation process of ammonium nitrogen in arable soil by biochar based on molecular dynamics simulation

The ammonia nitrogen in arable land soil is susceptible to environmental and anthropogenic influences, leading to nutrient loss. This study utilized indoor soil column leaching experiments, combined with adsorption mathematical models, traditional characterization methods, and molecular dynamics simulation methods, to analyze the effects of biochar on changes in ammonium ions in different soil layers and leachate of arable land soil. The study found that applying biochar at a ratio of 10 % to arable land soil could effectively increase the ammonium ion content in the 0–10 cm soil layer by 1.57–2.36 times and reduce loss by 44.83–72.27 %. The adsorption and fixation process of biochar is controlled by electrostatic attraction and ion exchange processes. Interactions between molecules, electrostatic forces, and system internal energy also have certain effects on the process. Near the structure of C6H12O6, there are low-energy adsorption sites for ammonium ions, which can provide the energy required for electrostatic attraction. Structures such as C5H10O5, C-S-H, C-SO3, and C4H7NO4 respectively play roles in physical adsorption or chemical adsorption through displacement reactions, electron exchange, and other forms. The adsorption free energy is −394,590.84 kcal/mol, indicating stable adsorption and a process that tends to interact with the biochar surface. This study addresses issues such as the easy loss of ammonia nitrogen in arable land soil and the unclear adsorption mechanism of biochar on ammonium ions, providing a theoretical basis for the field of environmental science.
