Background. The war started by the Russian Federation against Ukraine has become a challenge for Ukraine and requires significant changes in the system of training military personnel to acquire powerful capabilities in the defense of our state. Reserve officers are one of the categories of military personnel whose training requires special attention, therefore there is a need to improve the quality of selection and training of reserve officers. That is why the aim of the study was to work out an effective mechanism for the qualitative selection of citizens of Ukraine who are motivated and capable, in the course of obtaining a tactical level of military education, to master military-professional and military-special competences, duties for typical primary positions of officers, who expressed a desire to study under reserve officer training program. Methods. In the course of the study, theoretical methods were used for the study and comprehensive analysis of the scientific and theoretical development that has been formed today within the chosen subject. Results. The stages of conducting a longitudinal study in accordance with the multi-level method of psychological study of citizens of Ukraine during the competitive selection for military training under the reserve officer training program are proposed. The requirements for candidates for training in the L-1A basic course have been determined, among which the following can be distinguished: a sufficient level of mental abilities, psychological stability, an analytical thinking style and the presence of organizational abilities. Candidate evaluation criteria are proposed. The methodological principles for the further conducting of an expert survey, if necessary, were considered. Conclusions. The developed multi-level method of psychological study of candidates for training under the reserve officer training program will provide an opportunity to optimize the process of psychological study of candidates for military training under the reserve officer training program.

The study of the experience of conducting an anti-terrorist operation (ATO) and an operation of the United Forces (OUF) in the war against the Russian Federation allows us to conclude that today the use of modern means of fire damage in combination with new approaches to intelligence conducting has had a significant effect on increasing the intensity and speed of troops movement during hostilities. In such conditions, random (unforeseen) consumption of fuel may appear with a simultaneous sudden decrease in its reserves below the specified (acceptable) norms. An unexpected drop in fuel reserves in military equipment can be related to many factors and, as a result, create conditions that will not allow to perform tasks in the offensive, during the development of success and when solving other combat tasks in the next day of hostilities. In order to ensure the fulfillment of combat missions by units and subunits of the Armed Forces and to prevent the limitation of their combat capability in connection with an unforeseen shortage of fuel during the operation, there is a need to develop a mathematical model, the use of which in the future will allow to calculate the time after which the level of fuel reserves will decrease below the permissible norm, and in the dynamics of the work of the logistics headquarters, it contributes to the timely provision of the troops needs. In the article, for the first time, simple expressions were obtained for calculating the required sample volume of a random fuel consumption value in the UAF subunits and for the error of estimating the mathematical expectation of this value in the sample, which guarantees the fulfillment of the requirements for the accuracy of calculations with a sample size significantly smaller than the traditional one and without using the concepts of "confidence interval" and "confidence probability", and corresponds to the limited capabilities of the Ukraine Armed Forces subunits to collect statistics during hostilities. The developed model can be used for further development of mathematical tools for predicting possible fuel consumption, for predicting needs and for providing the troops with fuel up to the established standards in a timely manner.

Published: October 2024

Background: Many college students accumulate low levels of physical activity and even more so since the COVID-19 pandemic. Instructional physical activity programs (IPAPs) are a viable option for students to increase physical activity levels, but the reasons students take these courses have not been explored since the pandemic.
Aim: This pilot study explores the reasons students choose to take courses in an elective IPAP program.
Methods: This study employed a survey-based approach to investigate the reasons behind college students’ enrollment in IPAPs following the COVID-19 pandemic. The survey (n = 85) included demographic information, reasons for taking a course, courses students would have interest in taking, and preferred length and delivery mode.
Results: Findings revealed that the top three reasons for females to sign up for an activity course were: (1) wanted to learn a new activity, (2) to exercise regularly, and (3) to improve fitness. For males, the top three reasons were: (1) wanted to have fun, (2) to improve skills of the activity,  and to (3) to exercise regularly.
Conclusions: Results from this study show high alignment and slight differences with similar research done prior to the COVID-19 pandemic. Overall, students appear to enjoy fun, fitness-based, and novel course options in IPAP programs.
College/University Instructional Physical Activity Program Support: History, Advocacy and Wellbeing Promotion Enhancement Through Inaugural National Summit
Authors: Nanney Lindsey W. , Olsen Amy D.
Published: October 2024

College/University Instructional Physical Activity Programs (IPAP) have a long history in higher education and can effectively promote wellbeing among a large number of students. Despite IPAP benefits, prevalence has declined over the last few decades. Quality assurance, support, advocacy, innovation, and assessment are needed to strengthen IPAP. However, organizational support and resources for IPAP are lacking; thus, an inaugural National IPAP Summit was hosted in the Fall of 2023 to bring together IPAP professionals. Education, networking, support, resources, and innovative ideas were offered at the summit. Participants had unanimous positive feedback and support of future endeavors for IPAP professionals. Professional organization endorsement is needed to continue to offer opportunities, education, and support for IPAP professionals to maximize the wellbeing promotion potential and sustainability of IPAP.

Authors: Fedchenko V.I. , Kaloshin A.A. , Kaloshina S.A. , Medvedev A.E.
Published: October 2024

The interaction of sheep and mouse polyclonal antirenalase antibodies obtained by immunization with full-length human (RNLS1-human) and rat (RNLS2-rat) renalases, respectively, has been studied. The target recombinant proteins, RNLS1-human and RNLS2-rat, were expressed in E. coli cells and isolated by Ni-agarose chromatography. Sheep polyclonal antibodies against RNLS1-human interacted more effectively with both RNLS1-human than with RNLS2-rat. Mouse polyclonal antibodies against RNLS2-rat effectively interacted mainly with RNLS2-rat, but not with RNLS1-human. The data obtained indicate the preferential selectivity of the antibody interaction with the proteins against which they were obtained. This should be taken into consideration in the case of selection of commercially available antibody preparations for quantitative immunodetection of target proteins in biological objects.

Continued Long-Term Ecological Monitoring in a Northern Red Oak-White Pine Research Forest Over Five Decades
Authors: Johnson Logan , Murray Paulina
Published: October 2024

A red oak-white pine ecosystem on Maine’s coast, Holt Research Forest (HRF), has filled a key niche of long-term ecosystem monitoring since its establishment in 1983. While many landowners in Maine steward oak-pine forests, HRF is a rare research generator on this critical forest type. A recent harvest at HRF in the fall of 2020 provided a timely opportunity to monitor and distribute data on the impact of disturbance on oak-pine ecosystems, particularly in the context of climate change. With funding provided by the Forest Ecosystem Monitoring Fund through Forest Ecosystem Monitoring Cooperative, we collected, digitized, and distributed pre- and post-harvest data on overstory composition and regeneration at HRF. This effort gave landowners practical data and tools to inform their management while providing researchers with a long-term foundational dataset for future studies. It additionally contributed to an established body of research from HRF, housed by FEMC, tracking ecosystem change on-site as climate change shifts ecological systems across the region. Lastly, the project contributed to workforce development in forestry and forest research by providing students and early-career professionals with practical, applied experience working in the field and with HRF datasets.

Authors: Bujold Audrey , Gervais Christine , Pariseau-Legault Pierre
Published: October 2024

Les accouchements non assistés (ANA) font référence au fait que certaines femmes choisissent de vivre un accouchement en l’absence de professionnel·les de la santé alors que des structures médicales sont normalement disponibles pour les soutenir si elles le désirent. Au Québec et ailleurs dans la francophonie, à notre connaissance, aucune recension des écrits n’a été publiée malgré les questionnements croissants concernant ce phénomène. Cet article vise ainsi à présenter les résultats d’une recension systématique des écrits (n=32) qui porte précisément sur les ANA. Nos résultats décrivent le profil sociodémographique des femmes qui choisissent les ANA, les motivations et le processus décisionnel lié à ce choix, les risques socioculturels auxquels ces femmes sont exposées et la place qu’occupent les réseaux socionumériques dans ce processus décisionnel. Afin d’élargir notre compréhension de ce phénomène, nos résultats sont ensuite mis en dialogue avec d’autres situations de non-recours aux services de santé et d’autres pratiques familiales alternatives.

Published: October 2024

An experimental study was carried out to examine eight mixtures made with pumice powder and fly ash in order to produce lightweight materials. Additionally, textile fiber was utilized to increase strength of the lightweight concrete. It was found that 28 days compressive strength, thermal conductivity, sound transmission speed, water absorption and unit weight varied from13.0 to 20.9 MPa, 0.34 to 0.43 W/mK, 2.52 to 3.11 km/s, 14.3 to 17.5 % and 1.19 to 1.40 g/cm3 , respectively. It was seen form SEM pictures of samples that reaction products of cement were formed. In all samples, there was no deformation due to temperature from 300 to 700°C. However, at 900°C, all samples were deformed and showed cracks of 3 mm. The compressive strengths of cracks samples were obtained from 8.1 to 10.2 MPa. The results showed that pumice and fly ash decreased thermal conductivity and sound transmission. Also, samples were not decomposed at high temperature when pumice and fly ash used as admixtures in lightweight concrete.

Published: October 2024

Most applications today are designed to be networked. It is natural that such applications operate on some data. Such applications are multi threaded by nature and it is a common situation when few clients are using the same application at the same time. So it is possible that those users operate with the same data. It is possible that in such an operation some data might be treated incorrectly or some client instance may operate on outdated data. In order to avoid such situations proper consistent testing should be performed. Therefore it is complicated to perform such testing manually. Automated tool which would help to solve this problem is wanted. In this paper we are presenting an automated testing method that is able to detect problems related to resource racing conditions in a distributed system.

Authors: Gecer Aynur , Amac Ayse Ergun , Aras Faruk
Published: October 2024

In this study, the effects of case-based learning (CBL) and learning styles on the achievement and attitude of students towards an occupational health and safety (OHS) course are investigated experimentally. A total of 50 students in their first year at the electrical education department at Kocaeli University participated in this research. The students were split into two equal groups according to their scores in the central university entrance exam conducted every year by the high education consul in Turkey. The students were assigned to the control and experimental groups randomly. The control group students processed the OHS course materials using the traditional methods, while the experimental group students processed them through the CBL method in the environments developed by the authors regarding to their learning styles. According to the results of the analysis, the CBL method based on learning styles applied to the experimental group students is significantly effective in increasing students’ success in the OHS course. The findings also show that for OHS training, the CBL method based on learning styles, which has not been applied in previous studies, has a great effect on the students’ performance compared to the traditional teaching methods.

Authors: Prasad Raju Nidadavolu Venkat Durga Sai Siva Vara , Devi Penmetsa Naveena
Published: October 2024

As the volume and complexity of data continue to grow, predictive analytics has emerged as a vital tool for extracting actionable insights from big data, driving decision-making across various domains such as healthcare, finance, and e-commerce. However, selecting an appropriate machine learning algorithm for predictive analytics applications is challenging due to differences in algorithmic performance, computational requirements, and scalability, especially in the context of big data. This paper provides a comprehensive comparative analysis of popular machine learning algorithms utilized in predictive analytics, specifically focusing on their effectiveness and feasibility in big data environments.
The study categorizes algorithms based on learning types—supervised, unsupervised, and reinforcement learning—and evaluates their performance across multiple dimensions: prediction accuracy, computational efficiency, scalability, and suitability for real-time analytics. Through a detailed analysis of algorithms, including linear regression, decision trees, support vector machines, neural networks, and clustering techniques, we assess each method’s strengths and limitations in handling large datasets. Additionally, the study introduces a series of metrics, such as accuracy, F1-score, and training time, as benchmarks for assessing the algorithms’ predictive capabilities and computational viability.
A hypothetical case study demonstrates the application of these algorithms on a sample big data set, providing insights into their real-world performance across different predictive analytics scenarios. Visual data representations, including comparative tables and performance graphs, offer a clearer perspective on the trade-offs among algorithm choices. The findings highlight that while certain algorithms like random forests and neural networks achieve higher accuracy in prediction tasks, they may also require substantial computational resources, posing limitations for real-time processing in big data applications.
This paper concludes with recommendations for selecting machine learning algorithms based on specific predictive analytics objectives, data characteristics, and processing requirements. Furthermore, it discusses the challenges associated with implementing these algorithms in big data contexts and explores potential advancements, such as the integration of deep learning and the use of distributed computing, as promising directions for enhancing predictive analytics performance in future applications.

Katarzyna de Lazari-Radek przeprowadza współczesną obronę hedonizmu, biorąc pod uwagę argumenty filozoficzne, neuronaukowe i psychologiczne. Stawia śmiałą tezę, że przyjemność to stan mentalny, który sam w sobie jest „godny pożądania”. Porusza zagadnienia: dobrostanu, szczęścia, dobrego życia, wartości i perfekcjonizmu. Podejmuje też polemikę z takimi filozofami, jak Robert Nozick, Gilbert Ryle i Fred Feldman.
Życie człowieka może być dobre na wiele sposobów. Można być wybitną pianistką, której chcą słuchać ludzie na całym świecie, najlepszym kucharzem, który dostał kolejną gwiazdkę Michelin, podziwianą pięknością, której pożąda wielu mężczyzn. Czy jest coś wspólnego tym różnym drogom dobrego życia, co pozwala nam dokonać pozytywnej oceny, nawet jeśli jest ona ograniczona tylko do pewnego jego aspektu? Kiedy możemy powiedzieć o naszym własnym życiu, że jest dobre? Co jest naszym dobrostanem i w jaki sposób mamy go realizować w naszym życiu? Będę bronić tezy, że tym, co dla nas ostatecznie dobre, jest przyjemność rozumiana jako godny pożądania stan świadomości.

Published: October 2024

Sensing and Detection Technology is a core course in engineering specialties. Traditional sensor teaching methods have obvious deficiencies in cultivating students’ ability. To better foster students’ comprehensive qualities, this study explored a 4D1P (Four Dimensions and One Penetration) teaching mode. We independently developed an industrial sensor teaching platform with intellectual property rights, integrating classroom and sensor experiments to address the disconnection between traditional sensor teaching and practical application. This mode combined the teaching platform with SPOC (small private online courses) and Rain Classroom teaching software, enriching classroom teaching and stimulating students’ interest. By applying industry-academia-research integration to sensor teaching, students’ horizons were broadened and their creative thinking enriched. The mode set up discussion-based learning in the classroom, making the class atmosphere lively. Throughout the teaching process, data-driven learning and teaching evaluation were consistently applied, allowing teachers to promptly understand students’ learning situations. Data shows that under the backdrop of the COVID-19 pandemic, students’ grades improved and they were satisfied with this teaching mode. This mode solves most current problems in university classroom teaching and significantly enhances students’ practical abilities. It also has certain significance for education in other disciplines.

KLASİK TÜRK ŞİİRİNDE VUSLAT
Authors: Özerol Nazmi
Published: October 2024

Klasik Türk şiirinde geleneksel bir aşk anlayışı olduğu için bu aşkta fizikî görünümü ve karakter özellikleriyle ortak bir sevgili tipi vardır. Sevgili, sınırsız güç ve kudret sahibi bir padişah gibidir. Güzellikte onun eşine rastlamak mümkün değildir. Sevgilinin yüzü, yanağı, boyu, beli, gözü, bakışları, saçı, ağzı, dişleri, dudakları, kaşı, kirpiği, benleri, yüzündeki tüyleri, sinesi idealize edilmiş bir şekilde takdim edilir. Mükemmel ve kusursuz olan sevgili, bu cezbedici özellikleriyle âşığın hayranlık duygusunu uyandırır, ancak Klasik şiirde aşk tek taraflı yaşandığı için âşık bu ilişkinin acı çeken kişisidir. Âşığın en büyük arzusu sevgiliye kavuşmak olsa da sevgilinin buna pek de müsaade etmediği görülür. Vuslat yolunun acıdan, sıkıntıdan, gözyaşından geçtiğini bilen âşık, türlü zorluklara göğüs gerse de bundan genellikle şikâyetçi olmaz. Âşık için bu yolda verilen mücadele kutsaldır ve çekilen sıkıntılar, aşkın ta kendisidir. Klasik şiirde vuslat, çok yüce bir değer olarak görüldüğü için onunla ilgili geliştirilen imajlar da dikkat çekicidir. Şairler; benzetme, istiare, telmih gibi edebî sanatlardan yararlanarak bu kavramla ilgili özgün bağdaştırmalar ortaya koymuşlardır. Vuslat, mutluluğu ve sonsuzluğu çağrıştırdığı için gökyüzü, bir umut olduğu için güneş, âşığın nefes aldığı, huzur bulduğu bir bahçe ya da gönül gemisinin ulaşmak istediği bir deniz olarak tahayyül edilmiştir. Vuslat, bir nimet olduğundan sofra, lokma, şeker, güllaç, helva, bal; taşıdığı yüksek değerden dolayı cevher, inci, hazine, sermaye gibi görülmüştür. Vuslat, bazen bir bayram ya da cennet sevinci, bazen de çıkılan kutsal yolculuğun erişilmek istenen Kâbe’sidir. Vuslat, bir mum olunca âşık da onun için kendini yakan pervane olmuştur. Sevgiliye kavuşmak, bazen saltanatla bazen de en büyük nimet olan hayatla özdeşleştirilmiştir.

Published: October 2024

Doksorubisin, çeşitli katı tümörlerin tedavisinde yaygın olarak kullanılmaktadır. Doksorubisin güçlü antineoplastik aktivitesine rağmen kardiyotoksik etkisi nedeniyle kullanımı sınırlıdır. Bu çalışmada doksorobusin kaynaklı kardiyotoksisitede insülin benzeri büyüme faktörünü (IGF)-1 koruyucu rolünü değerlendirilmesi amaçlandı. Otuz iki adet sıçan 4 gruba ayrıldı: Kontrol, Doksorubisin (4 mg/kg/hafta), IGF-1 (2 günde bir 1 µg /kg), doksorubisin (4 mg/kg/hafta)+ IGF-1 (2 günde bir 1 µg /kg).Doksorubisin ve IGF-1 intraperitoneal olarak uygulandı. Dört hafta süren ilaç uygulamalarının ardında anestezi altında kalp ve kan örnekleri alındı. Biyokimyasal analizlerde kan serumundan CK-MB ve Troponin-I seviyeleri ölçüldü. Kalp dokusunda TAS, TOS, TNF-α, ve IL-6 düzeyleri ELISA yöntemiyle ölçüldü. iNOS, HIF-1α, SERCA2a, LC3, Beclin-1 ve SQSTM1 mRNA ekpresyon düzeyleri RT-PCR ile analiz edildi. Histolojik ve immünohistokimyasal (Kaspaz-3 ve ICAM-1) analizler yapıldı. Doksorubisin kalp hızını azaltırken kuyruk kan basıncını düşürdü ve serum CK-MB ve Troponin-I seviyelerini artırdı.

Fluorescence-Based Study of Oligonucleotide Interactions With Recombinant Proteins: Insulin, Interferon α2-β, Somatotropin, and Their Receptors
Authors: Nuzhnyi Oleksandr , Nikolaiev Roman , Tkachuk Zenovii
Published: October 2024

Background. Oligonucleotides (OLNs) can participate in a wide range of protein-ligand interactions and perform numerous cellular functions by forming structures that enable specific interactions with DNA, RNA, and proteins, what is crucial for many biological processes. Advances in understanding these interactions could lead to the development of new technologies for treating various diseases. However, the mechanism of interaction between proteins and OLNs is complex and still requires detailed study. More research is needed to fully elucidate this process and enhance our understanding of these biomolecular interactions.
Objective. The aim of this study was to synthesize, purify, and investigate the interaction of OLNs with recombinant signaling proteins interferon α2-β and insulin with their receptors and somatropin by assessing binding strength using fluorescence spectroscopy.
Methods. The interactions were analyzed using the Stern–Volmer equation in both general and modified forms, as well as the Hill equation. OLNs were synthesized via the solid-phase phosphoramidite method, purified through solid-phase extraction, and subsequently verified with a spectrophotometer.
Results. Fluorometric titration revealed that OLNs bind to proteins within the medium affinity range, forming non-fluorescent complexes, with the most active interactions observed with shorter OLN. Positive cooperative binding of interferon to G20 and T20, and negative cooperative binding of insulin to C20 and A20, were identified. Additionally, negative cooperative binding of somatropin to C20 was observed.
Conclusions. The study demonstrated the interaction between OLNs and recombinant signaling proteins and receptors through various binding mechanisms, which could potentially affect their conformation and biolo­gical activity. These findings have implications for the therapeutic use of OLNs in the context of signaling proteins and receptors.
The Temporal Dynamics of Corruption in Decentralised Water Utilities: A Longitudinal Study
Authors: Horesh Edward
Published: October 2024

This study examines the temporal relationship between decentralisation and corruption in water supply schemes across two large Indian states. Utilising a difference-in-differences approach and experiential corruption measures, we analyse the impact of decentralising water utilities from state to local government control. Our findings challenge the prevailing assumption that decentralisation inherently reduces corruption. Instead, we observe a significant increase in corruption immediately following decentralisation. However, this surge diminishes substantially over time, though a residual rise continues in the medium term. These results suggest a nuanced connection between decentralisation and corruption, characterised by an initial learning curve for local governments. Our research contributes to the limited literature on sub-national decentralisation and corruption, offering insights into the dynamic nature of this relationship. The findings have important implications for policymakers and development practitioners, highlighting the need for targeted support during the transition to decentralised governance.
Effects of Electromagnetic Waves on the Level of Fatty Acids in UHT Milk
Authors: Migdał Anna , Zapletal Piotr
Published: October 2024

The aim of this study was to determine whether long-term storage of UHT milk and its heating in a microwave has an impact on the fatty acid profile. Material consisted of 4 types of UHT milk from different manufacturers with a fat content 3.2%. Analyses conducted for 13 days. Milk stored in the original container in a refrigerator at 4°C. Milk samples after opening the package was heated for 1 and 2 minutes in a microwave. Estimated absolute density, acidity, freezing point, electrolytic conductivity and solid non fat, crude fat, lactose, total protein and minerals. Physical and chemical parameters of milk were carried out using ultrasonic analyzer Lactoscan MCC. The fatty acid composition was determined using a gas chromatograph. Fatty acid methyl esters identified by comparison with the standards (Supelco 37 Component FAME). UHT milk storage after opening at 4 °C and heating in microwave for 1 or 2 minutes (microwave power for 1100 W and power heater 750 W) did not result in the period of 13 days significant changes in the fatty acid profile. Also were not stated other significant changes in the values of physical and chemical parameters of milk during the experiment. Differences that occurred in the electrolytic conductivity may result from evaporation of water during storage of milk and heating, as indicated by its freezing point. On this basis, it can be concluded that storing milk in the fridge and reheat in the microwave does not have a significant impact on its physicochemical properties and fatty acid profile.
From Neural Crest to Jaws: How Cell Innovation Reshaped Vertebrate Evolution and Marine Ecosystems
Authors: Montgomery Richard Murdoch
Published: October 2024

The evolution of jaws represents one of the most transformative innovations in vertebrate history, fundamentally reshaping both animal anatomy and ecological dynamics. At the core of this innovation lies the neural crest, a unique vertebrate cell population whose molecular and developmental properties enabled the formation of articulated jaws. This review explores how neural crest cells, as multipotent stem cells, contributed to jaw development through their extraordinary capacity to form cartilage, bone, and associated tissues. Beyond the developmental perspective, we examine how the emergence of jawed vertebrates dramatically altered marine ecosystems, leading to new predator-prey relationships and driving an unprecedented diversification of feeding strategies. This innovation triggered an evolutionary arms race that shaped marine biodiversity and established new trophic relationships that persist in modern oceans. Understanding this ancient innovation provides crucial insights into both developmental mechanisms and ecological dynamics that defined vertebrate evolution.
School-Based Agricultural Education Teachers’ Interest in and Confidence for Preparing Students to Compete in Career Development Events
Authors: Robinson Shane , Dreher Caitlin
Published: October 2024

School-based agricultural education (SBAE) teachers have an obligation to teach students about agriculture and prepare them for agricultural careers. Yet, considering the vast number of sectors within the agricultural industry, this task can be daunting. One way teachers can accomplish this mission is through preparing their students to participate in Career Development Events (CDEs). This study assessed SBAE teachers’ level of self-efficacy for each of the 33 CDEs recognized and offered at the [State] State FFA Interscholastic Event. The SBAE teachers surveyed in the study expressed a greater interest in preparing their students in 32 of the 33 CDEs than they did their confidence to prepare them. Such perceptions may lead to a reluctance to prepare students for CDEs, especially in areas where teachers feel less efficacious, which could cause students to have less awareness of, appreciation for, and preparation in various agricultural careers. The findings of the study have implications for the professional development needs of inservice SBAE teachers. Such professional development should be provided to develop SBAE teachers’ perceived inadequacies by targeting the CDEs with the greatest mean difference scores. Specific focus should be placed on food science and technology, veterinary science, and meat evaluation and technology CDEs. SBAE teachers should be provided opportunities to develop mastery in these areas by pairing teachers with expert mentors across the state to allow for vicarious experiences to evolve and complement their perceived shortcomings. Additional research should ensue to determine the impact CDEs have on students’ future career choices and employability.

Published: October 2024

National energy system models are vital to climate policy. However, they do not assess environmental impacts beyond territorial greenhouse gas (GHG) emissions. Here, we evaluate a territorial net zero GHG emissions energy scenario for Switzerland coupled with life-cycle assessment to quantify non-domestic environmental burdens. We stress the limited insights from considering territorial GHG emissions only. Indeed, significant GHG emissions persist outside of Switzerland by 2050 (~3-5 Mtons CO2-eq./year) because of imports and energy related infrastructure, even though domestic emissions are reduced to net zero. Global climate policies influence the extra-territorial GHG emissions Switzerland is responsible for. Additionally, we must broaden the spectrum of environmental indicators in the context of many countries’ ambitions to achieve net zero goals. Our findings highlight the trade-offs involved, showing how environmental impacts other than those on climate change (ecosystem impacts, air pollution, natural resource use) could increase and shift from Switzerland to the rest of the world as the country electrifies its economy.
