Authors: Narandžić Tijana , Tanjga Biljana Božanić , Ilić Olivera , Ljubojević Mirjana 
Published: December 2024

Summary
The aim of this study was to investigate the morphological traits and fragrance-related volatile compounds in three garden rose cultivars from the 'Fragrant Frayla' collection: 'Draga Frayla', 'Jelena Frayla', and 'Lenka Frayla', bred by the private breeding company Pheno Geno Roses. The roses were cultivated under open-field conditions in Temerin, Serbia, without irrigation and chemical treatments. Vegetative and generative properties were assessed in June and September 2023, while headspace volatile extraction and gas chromatography–mass spectrometry (GC-MS) were employed to identify scent-related volatiles. All three cultivars exhibited high ornamental value, with shrub heights ranging from 47 to 67 cm, semi-upright to upright growth habits, double flowers with diameters from 6.6 to 8.2 cm, and petal counts from 35.8 to 83.8. Upon sensory evaluations, 'Draga Frayla', 'Jelena Frayla', and 'Lenka Frayla' were characterized by moderately strong, strong and moderate fragrances, respectively. Volatile analysis detected the presence of phenylethyl alcohol (up to 57.31% in 'Draga Frayla'), terpenoids (a total of 28.2% for citronellol, geraniol, and nerol, found exclusively in 'Jelena Frayla'), and hydrocarbons. Hydrocarbons containing fewer than 30 C-atoms were predominantly found in 'Draga Frayla' (accounting for approximately 25% of the total peak area), while those with more than 30 C-atoms were present at less than 20% in the strongly scented roses. The highest number of volatiles was detected in 'Jelena Frayla', the rose cultivar identified as the most fragrant. The results revealed a correlation between strong fragrance intensity and elevated levels of phenylethyl alcohol and alcoholic monoterpenes, whereas a diverse array of hydrocarbons, rather than their concentration, appeared to enhance scent emission.
The Single-Sex View of Gender and Gender Inequality in a Nigerian Ivory Tower
Authors: Asiazobor Eboiyehi Friday 
Published: December 2024

Abstract
This paper examines gender inequality in a female dominated academic unit in a purposefully selected university in south-western Nigeria. It examines the participants’ understanding of the terms "gender", “men doing gender”, establishes how these perceptions affect male staff and students doing gender, and suggests what can be done to encourage men to participate in gender studies. One of the federal universities in Nigeria that has a Gender Studies Unit was purposively selected. In all, 256 semi structure questionnaires were administered. Out of these numbers, 200 questionnaires were retrieved and analyzed. The results showed that less than 50% (49%) of the respondents defined gender study as the study of men and women. Others (2%) understood gender be the study of men, while 10% had no clear understanding of what gender means. Also, 45% of the respondents said gender is about women and men, 44% stated it was about women, 4% had no clear idea of what gender implies, and 1% of them affirmed that gender is about men. On the perceptions about “men doing gender”, 22% of the respondents were of the view that a negative perception about “men doing gender” would make them lose confidence in themselves, 21.5% stated it would limit their capacity to develop their full potential, and 21% believed it might have adverse effects on men’s career progression. About 20.5% of the respondents affirmed that such a perception would create a lack of interest in this field of study, while 15% affirmed that it would limit their interest in pursuing a career in gender studies. The policy implications of the study were also highlighted and discussed.

Published: December 2024

Abstract

Objective
The occurrence of some public health events inevitably endangers medical personnel, and medical personnel, as a special group, have to resume work on time to treat patients. This coronavirus disease-2019 (COVID-19) infection is a good example, and what intensive care unit (ICU) nurses experience as the primary caregivers of critically ill patients after COVID-19 infection is our focus. To explore the work experience of ICU nurses after recovery from COVID-19, and to provide a theoretical basis for the intervention to improve the physical and mental health level and work experience of special workers in public health emergencies.

Methods
We conducted an explorative descriptive study using an inductive thematic analysis. Using the maximum differential sampling method, a semi-structured interview was conducted among 13 ICU nurses suffered from COVID-19 in a tertiary grade A hospital in Qingdao, Shandong Province. This study carried on the theme analysis according to the inductive content analysis method and used MAXQDA 2020 Analytics Pro (VERBI Software GmbH, Berlin, Germany) to manage and summarize the interview data.

Results
After being infected by the virus, SARS-Coronavirus-2 (SARS-CoV-2), the pathogen of COVID-19, the work experience of ICU nurses was extracted from the following 5 themes: (1) Stress and challenge caused by the change of work focus; (2) downsizing, overtime, taking up work with illness, and physical discomfort; (3) dedication and family debt; (4) unknown fear and helplessness; and (5) professional responsibility and sense of benefit.

Conclusions
Under the pressure of COVID-19, ICU nurses face multiple pressures and challenges, and their emotions are complex. We suggest that nursing managers should take corresponding measures to alleviate nurses’ physical and psychological pressure and improve their work experience.

Authors: Correia Vitor , Falck Eberhard , Komac Marko 
Published: December 2024

Abstract
This paper examines the challenges in implementing the EU’s raw materials policy, including conflicts between minerals extraction, Green Deal objectives, nature restoration targets and public opposition to mining projects. It explores innovative approaches such as invisible mining, enabled by advancements in robotics and miniaturisation, comprehensive and integrated resource recovery principles and materials-as-a-service business models, which can minimise environmental impacts and enhance social acceptability. The paper argues that successful implementation of the EU’s Critical Raw Materials Act requires a multifaceted approach, building on technological advances and encompassing policy harmonisation, socio-economic innovation and skills development. By adopting this comprehensive strategy, the EU can create a more sustainable and socially responsible mining industry, addressing the immediate need for critical raw materials while positioning itself as a global leader in responsible mining.

Authors: Koll Willi , Merz Wolfgang 
Published: December 2024

Abstract
This year marks the 25th anniversary of the EU’s Macroeconomic Dialogue (MED). Since entering its third decade, the MED has already faced two massive crises: the COVID-19 pandemic and the surge in energy prices. Yet European economic policymakers continue to face multiple macro-structural challenges that will also have an impact on the future work of the MED. This article explores the role of the MED during the two recent crises and considers its evolving responsibilities, particularly in light of the EU’s goal of climate neutrality.
An Examination of Generational Differences in the Sharing Economy: Understanding the Motivations of Idle Asset Owners and Their Impact on Peer-to-Peer Platform Management
Authors: Pelech Pavel , Dědková Jaroslava 
Published: December 2024

Abstract

Background/Purpose
This research examines the dynamics of sharing idle assets on peer-to-peer (P2P) platforms within the sharing economy, focusing on understanding the motivational factors that influence asset owners across generations. Platforms that know what motivates asset owners to enter the sharing economy can more effectively set up and manage marketing communications and gain a competitive advantage.

Methods
A mixed-methods approach has been adopted, which includes both quantitative and qualitative data collection and analysis. The analytical tools used include descriptive statistics, Kruskal-Wallis test, PCA and Welch ANOVA.

Results
We identified four motivation factors. We found out that supply-side generational marketing is appropriate to use if the marketing message targets opportunistic factors (completely new) or social factors; for user-related and social factors, generational marketing is unnecessary, i.e., P2P platforms do not need to distinguish the segment they are targeting with the marketing communication.

Conclusion
This research reveals how generational differences impact motivations to participate in the sharing economy, aiding P2P platform management. It offers a novel, comparative analysis of generational motivators, enriching sharing economy literature and providing practical insights for targeting different generations effectively. Understanding the motivations of idle asset owners is key to managing the business of P2P platforms.

Authors: Jereb Eva , Urh Marko 
Published: December 2024

Abstract

Background/Purpose
Artificial intelligence (AI) impacts our everyday lives, from business to social areas, and, in recent years, more and more education. This paper aims to discuss using artificial intelligence tools for educational purposes from the student’s perspective.

Methods
A quantitative approach was used for the research using the questioning method. Data were collected using an e-survey. The questionnaire contained closed questions referring to (i) general data, (ii) the use of specific artificial intelligence tools, and open questions (iii) about using artificial intelligence for study purposes. Parametric Independent – Samples t-Test and One-Way ANOVA tests were used for normal and near-normal distributions of the responses.

Results
The study conducted with 258 university students in Slovenia reveals a general familiarity with AI concepts yet with a limited ability to articulate this understanding. Popular AI tools like ChatGPT and Grammarly are predominantly used for information retrieval and idea generation. Notable differences in AI tool usage were observed based on gender and field of study.

Conclusion
The rapid advancement of AI is significantly transforming higher education. Integrating AI into education fosters the development of adaptive, personalized, and inclusive learning environments. Due to the study’s limited sample size and geographic focus, further research with more diverse samples is needed to understand global AI tool usage in higher education fully.
Using the Nominal Group Technique to Design an Appropriate Communication Strategy Among Strategic Procurement and Internal Stakeholders
Authors: Lenarčič Božidar , Faganel Armand 
Published: December 2024

Abstract

Background/Purpose
The implementation process of the procurement strategy requires consensus among internal stakeholders. An effective procurement strategy aligns with specific business requirements and accommodates the individual introversion of internal stakeholders. From the latter, we formulate our research question: How is the classification of internal procurement stakeholders designed in the validation of the procurement strategy? The research objective is to present the result in the form of a schematic description and a recommendation for a communication strategy, based on insights from existing theoretical knowledge and the formulation of professional references.

Methods
Nominal Group Technique (NGT) with 13 participants has been applied to analyze viewpoints on procurement functions. To ensure reliability and validity, Cronbach’s alpha test, Spearman coefficient, and t-tests have been used.

Results and Conclusion
Study categorizes internal procurement stakeholders into four groups based on their stance towards strategy implementation: positive, cautiously positive, negatively independent, and negative stake-holders. For each group, we recommend a tailored communication strategy that includes elements such as informing, guiding, motivating, and providing credible data. The research results offer important insights into the dynamics among organizational stakeholders and how communication impacts the success of strategy implementation. We have found that under-standing and adapting to various types of stakeholders are crucial for success, from those highly involved and positively inclined to those with the potential to oppose or hinder implementation. Employing specific communication strategies for each group can significantly enhance the chances of successful implementation and sustainable execution of strategies.
La formation du savant, entre solitude de la pensée et communauté de recherche
Authors: Landenne Quentin 
Published: December 2024

Cet article propose une lecture parallèle de trois grands textes du XIXe siècle portant sur les missions de l’université et la place que doit y occuper le savant comme individu singulier : The American Scholar donné par R. W. Emerson à Harvard en 1837, le discours inaugural de J. S. Mill à l’Université Saint Andrews en 1867, et les conférences de F. Nietzsche à l’Université de Bâle Über die Zukunft unserer Bildungsanstalten, de 1872. L’objectif de cette comparaison est de mettre en évidence des analogies et des différences éclairantes, en leur adressant une série de questions communes : celle, d’abord, de leur définition de l’idéal éducatif ou culturel, en écho au concept idéaliste allemand de Bildung ; celle ensuite de leur critique des mutations de l’université, comme symptômes majeurs de la crise moderne de la culture ; celle, enfin, de la caractérisation du « savant », de sa destination et de sa formation de soi, en tant qu’il est un individu à la fois voué à une exigence existentielle de solitude, mais aussi appelé à inventer de nouvelles formes de communautés culturelles et intellectuelles, en réponse à la crise de l’institution universitaire.
The gender of individuality in Harriet Taylor and John Stuart Mill
Authors: Knüfer Aurélie 
Published: December 2024

L’article propose une nouvelle généalogie de l’« individualité », notion centrale de l’ouvrage De la Liberté (1859), généralement attribué à John Stuart Mill. Il met en évidence le rôle majeur joué par Harriet Taylor dans l’élaboration de cette notion, et partant dans celle du texte dont elle est en réalité la co-autrice. Il montre que la philosophe conduit, dès le début des années 1830, une réflexion approfondie sur la formation du caractère et le perfectionnement de soi. Tandis que chez Mill, à la même époque, l’individualité est comprise comme le devoir-être de certaines « natures supérieures », principalement de genre masculin, elle constitue d’emblée pour Taylor une exigence épicène impliquant le développement de l’esprit comme celui des plaisirs sensibles et sexuels. Ainsi, c’est précisément grâce à son analyse de l’expérience douloureuse et propre aux femmes de privation d’individualité que Taylor réussit à formuler des propositions puissantes, novatrices et à la portée universelle sur l’éducation et la culture de soi.
Feynman integral reduction: balanced reconstruction of sparse rational functions and implementation on supercomputers in a co-design approach
Authors: Smirnov A.V. , Zeng M. 
Published: December 2024

Integration-by-parts (IBP) reduction is one of the essential steps in evaluating Feynman integrals. A modern approach to IBP reduction uses modular arithmetic evaluations at the specific numerical values of parameters with subsequent reconstruction of the analytic rational coefficients. Due to the large number of sample points needed, problems at the frontier of science require an application of supercomputers. In this article, we present a rational function reconstruction method that fully takes advantage of sparsity, combining the balanced reconstruction method and the Zippel method. Additionally, to improve the efficiency of the finite-field IBP reduction runs, at each run several numerical probes are computed simultaneously, which allows to decrease the resource overhead. We describe what performance issues one encounters on the way to an efficient implementation on supercomputers, and how one should co-design the algorithm and the supercomputer infrastructure. We present characteristic examples of IBP-reduction in the case of massless two-loop fourand five-point Feynman diagrams using a development version of FIRE and give illustrative examples mimicking the reduction of coefficients appearing in scattering amplitudes for post-Minkowskian gravitational binary dynamics.
Редукция с использованием интегрирования по частям (IBP) является одним из существенных этапов при вычислении интегралов Фейнмана. Современный подход к IBP-редукции использует модулярную арифметику при конкретных числовых значениях параметров в пробных точках с последующей реконструкцией аналитических рациональных коэффициентов. Задачи, возникающие на переднем крае науки, требуют применения суперкомпьютеров из-за большого количества необходимых проб. В этой статье мы представляем алгоритм рациональной реконструкции, который в полной мере использует преимущества разреженности, объединяя сбалансированный алгоритм реконструкции и алгоритм Зиппеля. Кроме того, для повышения эффективности редукции в модулярной арифметике при каждом запуске одновременно вычисляется несколько числовых проб, что позволяет сокращать потребляемые ресурсы. Мы описываем, какие проблемы появляются на пути к эффективной реализации на суперкомпьютерах и как следует совместно проектировать алгоритмы и соответствующую суперкомпьютерную инфраструктуру. Представлены характерные примеры IBP-редукции в случае безмассовых двухпетлевых четырехточечных и пятиточечных диаграмм Фейнмана с использованием частной версии FIRE, а также показательные примеры редукции, имитирующие редукцию коэффициентов, появляющихся в амплитуде рассеяния в рамках постминковской гравитационной бинарной динамики.

Jus jeruk dikenal mengandung vitamin C tinggi diperlukan oleh manusia tetapi vitamin C mudah mengalami fotooksidasi selama penyimpanan dan dapat menurunkan daya terima konsumen. Tujuan penelitian adalah menginvestigasi jus jeruk yang mengandung nanostructured lipid carrier (NLC-RPO) terhadap penghambatan fotooksidasi vitamin C perubahan pH, viskositas, turbiditas, warna, dan sifat sensoris. Penelitian dilakukan pada jus jeruk tanpa dan dengan penambahan 3 % NLC-RPO, sampel ditempatkan dalam refrigerator kondisi gelap (4 °C), gelap dan terang dengan paparan cahaya suhu ruang (28 °C, 874,59+399,39 lux selama 8 jam/hari) selama 0, 2, 4, 6, 7, 8, 14, 21, dan 28 hari. Hasil penelitian menunjukkan bahwa laju fotooksidasi vitamin C jus jeruk dengan 3 % NLC-RPO secara signifikan lebih rendah dibandingkan jus jeruk tanpa perlakuan (p<0,05). Penghambatan fotooksidasi vitamin C terlihat jelas pada jus jeruk dengan 3 % NLC-RPO (0,2152 mg/100 g.hari) dibandingkan tanpa perlakuan (0,6945 mg/100 g.hari) saat kondisi penyimpanan terang pada suhu ruang (28 °C). Laju viskositas dan perbedaan warna (∆E) jus jeruk dengan 3 % NLC-RPO signifikan lebih rendah dibandingkan tanpa perlakuan (p<0,05), sedangkan laju turbiditas, degradasi pH, L*, a*, dan b* tidak berbeda nyata (p>0,05). Panelis dapat membedakan secara nyata (p<0,05) antara jus jeruk tanpa dan dengan 3 % NLC-RPO pada 0 hari, begitu pula antara jus jeruk tanpa perlakuan pada 0 hari dan jus jeruk dengan 3% NLC-RPO 30 hari pada 30. Intensitas warna orange, aroma tidak enak, dan kekeruhan jus jeruk tidak berbeda nyata (p>0,05).
