Emergency Medical Access Control System Based on Public Blockchain
Authors: Takahashi Taisei , Zhihao Yan , Omote Kazumasa 
Published: September 2024

Abstract
IT has made significant progress in various fields over the past few years, with many industries transitioning from paper-based to electronic media. However, sharing electronic medical records remains a long-term challenge, particularly when patients are in emergency situations, making it difficult to access and control their medical information. Previous studies have proposed permissioned blockchains with limited participants or mechanisms that allow emergency medical information sharing to pre-designated participants. However, permissioned blockchains require prior participation by medical institutions, and limiting sharing entities restricts the number of potential partners. This means that sharing medical information with local emergency doctors becomes impossible if a patient is unconscious and far away from home, such as when traveling abroad. To tackle this challenge, we propose an emergency access control system for a global electronic medical information system that can be shared using a public blockchain, allowing anyone to participate. Our proposed system assumes that the patient wears a pendant with tamper-proof and biometric authentication capabilities. In the event of unconsciousness, emergency doctors can perform biometrics on behalf of the patient, allowing the family doctor to share health records with the emergency doctor through a secure channel that uses the Diffie-Hellman (DH) key exchange protocol. The pendant’s biometric authentication function prevents unauthorized use if it is stolen, and we have tested the blockchain’s fee for using the public blockchain, demonstrating that the proposed system is practical.
Feasibility of laser induced breakdown spectroscopy for quantification of zirconium in nuclear streams
Authors: Kumar Satendra , Maji S. , Sundararajan K. 
Published: September 2024

AbstractLaser induced breakdown spectroscopy is explored for the estimation of Zr in metallic fuel and pyrochemical reprocessing stream using filter paper as a sample substrate. Zr(II) emission line at 339.20 nm has been identified and used for its quantitative determination. Calibration curves are obtained after normalizing the intensity of Zr to C/Y emission lines as an internal standard, to get better linearity. Analytical capability of LIBS for Zr estimation is tested by comparing the measured value with ICP-OES in simulated samples. Good agreement between the measured values confirms the ability of LIBS application in nuclear streams.

AbstractAn imbalance between reactive oxygen species (ROS) production and antioxidant defense driven by oxidative stress and inflammation is a critical factor in the progression of neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Coriander (Coriandrum sativum L.), a culinary plant in the Apiaceae family, displays various biological activities, including anticancer, antimicrobial, and antioxidant effects. Herein, neuroprotective properties of three major bioactive compounds derived from coriander (i.e., linalool, linalyl acetate, and geranyl acetate) were investigated on hydrogen peroxide-induced SH-SY5Y neuroblastoma cell death by examining cell viability, ROS production, mitochondrial membrane potential, and apoptotic profiles. Moreover, underlying mechanisms of the compounds were determined by measuring intracellular sirtuin 1 (SIRT1) enzyme activity incorporated with molecular docking. The results showed that linalool, linalyl acetate, and geranyl acetate elicited their neuroprotection against oxidative stress via protecting cell death, reducing ROS production, preventing cell apoptosis, and modulating SIRT1 longevity. Additionally, in silico pharmacokinetic predictions indicated that these three compounds are drug-like agents with a high probability of absorption and distribution, as well as minimal potential toxicities. These findings highlighted the potential neuroprotective linalool, linalyl acetate, and geranyl acetate for developing alternative natural compound-based neurodegenerative therapeutics and prevention.

Published: September 2024

AbstractWe provide a new approach to obtain solutions of linear differential problems set in a Banach space and equipped with nonlocal boundary conditions. From this approach we derive a family of numerical schemes for the approximation of the solutions. We show by numerical tests that these schemes are numerically robust and computationally efficient.
International negotiations over the global commons
Authors: Rickard Stephanie J. 
Published: September 2024

AbstractCountries today navigate a multipolar world defined by tensions between great powers. How do middle powers, small states, and Global South countries fare in this geopolitical landscape? Can they shape new international agreements on emerging, divisive topics, like trade-and-environment issues? To explore this question, I investigate the twenty years of negotiations that led to a new treaty seeking to preserve the global commons: the World Trade Organization’s (WTO) Agreement on Fisheries Subsidies (AFS). Using text-as-data analyses and a rich trove of WTO documents, I investigate the sources of the treaty text. I find that middle powers, small states, and countries from the Global South contributed to the agreement; they did so by forming coalitions with like-minded countries. The findings demonstrate that a wider range of states can effectively participate in international negotiations than traditionally assumed.
The Differentiated Impact of Perceived EU Regional Policy on Citizens’ Positions on European Integration
Authors: Debus Marc , Schweizer David 
Published: September 2024

AbstractThe main goal of the regional development programme of the European Union (EU) is to decrease disparities in the economic situation between the regional units of the EU member states. An important side note effect of EU regional policy is that citizens should be able to directly identify the positive aspects of European integration when realising the impact of the EU for structural programmes in their city or region. We aim to evaluate this mechanism and ask whether the individually perceived benefit of EU regional funds in the home area of a respondent has a positive impact on their position towards European integration. Furthermore, we discuss how a relational perspective on EU regional funds—that is, whether a respondent considers other regions or other EU member states to benefit more from the EU regional funds than their own region—mediates the expected positive impact of EU regional funds on an individual’s position on European integration. We answer these questions by analysing new survey data conducted in two German states, Baden-Wuerttemberg and Thuringia, which differ significantly in terms of the regional funding they receive. The analysis shows not only that there is a significant difference in the positions of respondents on European integration between the two regions but also that perceiving personal benefits of EU regional funding increases the support for European integration. Furthermore, individuals’ thinking that their own region benefits more from EU regional funding than other regions tends to increase their support for European integration.
Towards supply chain resilience: A structured process approach
Authors: Stentoft Jan , Mikkelsen Ole Stegmann 
Published: September 2024

AbstractThis paper aims to enhance the understanding of how small and medium-sized enterprises (SMEs) can bolster their resilience to supply chain disruptions by engaging and aligning cross-functional staff in the process of developing supply chain resilience (SCRES). Employing process theory, the study adopts a multiple case-study methodology involving 18 Danish production SMEs across two iterative phases: an exploratory phase encompassing eight case companies, and a subsequent refinement phase involving an additional ten case companies. Utilizing a mixed-method approach comprising semi-structured interviews, card sorting exercises, observational studies, and a questionnaire survey, the research proposes a four-stage process for enhancing SCRES. This process includes: 1) mapping the supply chain, 2) identifying vulnerabilities and capabilities within each function, 3) prioritizing and creating cross-organizational alignment, and 4) developing action plans. The refined approach, validated through the ten Danish SMEs in the refinement phase, offers a practical and relevant framework for companies seeking to mitigate vulnerabilities and enhance capabilities in their supply chains. By strengthening SMEs' resilience against supply chain disruptions, this approach serves as a potential model for other companies striving to achieve SCRES.
Currying Favour with the Algorithm: Online Sex Workers’ Efforts To Satisfy Patriarchal Expectations
Authors: Palatchie Brittany , Beban Alice , Nicholls Tracey 
Published: September 2024

AbstractThe rise of the online sex work industry is reshaping how people conceptualise and negotiate sexual encounters across digital and offline spaces. This article analyses content from an online sex work forum (AmberCutie Forum (ACF)) to examine how online sex workers establish boundaries between their online and offline lives to manage competing expectations from their partners and viewers. Our analysis reveals a misogynistic double standard whereby workers are seen to threaten monogamous values, while viewers escape the same level of moral culpability. We argue that the cultural logics of monogamy function to delegitimise the labour involved with online sex work and increase the risk posed to online sex workers through retributive misogyny, including cyber-harassment toward sex workers. This impacts sex workers’ emotional and financial wellbeing and reinforces gendered power relations by prioritising stereotypically masculine pleasure over workers’ economic interests.

Published: September 2024

AbstractSince it was shown that Alzheimer’s disease (AD) begins many years before the onset of symptoms with subjective cognitive decline (SCD), there has been increasing interest in the early clinical stages where disease-modifying drugs are expected to have the greatest benefit. However, at this early stage cognitive testing may yield unremarkable results, it is necessary to find a tool that can provide a simple and reliable indication of SCD as a part of a screening tool for AD in the general population. The German version of the 24-item Subjective Cognitive Decline Questionnaire (SCD-Q) with a dichotomous answer scale was tested, which then revealed some challenges. For this reason, an adaptation of the questionnaire was necessary. 360 participants completed the SCD-Q, all of whom were outpatients at a memory clinic. The most relevant subitems were identified by principal component analysis. This analysis focused on the self-perceived perspective of the decline. Results of the principal component analysis, consultations with experts and feedback from respondents were integrated into a short version of the SCD-Q with 17 items and a Likert scale – the SCD-Q17. The SCD-Q17 was sent to 100 participants of the original questionnaire for re-completion and, a new cut-off value was calculated by receiver operator characteristic (ROC) curves. The SCD-Q17 is a useful tool for the reliable detection of subjective symptoms, and thus may prompt more in-depth assessments of the underlying etiology. CogScreen has been retrospectively registered at clinical trials (NCT06191952).
Inducing inhibition affects propagation of uncertainty and checking behaviors
Authors: Adler Hodaya , Eitan Renana , Linkovski Omer 
Published: September 2024

AbstractDifficulty tolerating uncertainty is a central deficit across psychopathologies, and checking behavior is a common response to uncertainty. Inducing inhibition improves resolution of uncertainty. However, it is unclear whether inducing inhibition improves decision-making under conditions of uncertainty or whether it reduces checking. This study evaluated how inducing inhibition affects resolution of uncertainty and checking separately. Healthy adults (N = 34) completed three experiments combining an inhibition-induction task with a novel visual-matching task, which dissociated resolving uncertainty from checking. In Experiment 1, the visual-matching task included only “certainty” trials with unlimited checking. In Experiment 2, the task featured “certainty” and “uncertainty” trials, without checking. In Experiment 3, the task featured “certainty” trials, without checking. All participants completed self-report assessments of relevant clinical constructs including obsessive-compulsive symptoms and depressive symptoms. Our results indicate that inducing inhibition reduces unnecessary checking in “certainty” trials. Inducing inhibition also improves accuracy in “uncertainty” trials when checking is impossible, by limiting the harmful propagation of uncertainty. The propagation of uncertainty correlated with depressive symptoms and checking correlated with obsessive-compulsive symptoms. Our results offer a novel measure of different uncertainty facets and demonstrate the interactions between inhibition, uncertainty, and checking. We also outline implications for understanding specific uncertainty facets in psychopathologies and suggest that inducing inhibition may play a role in alleviating certain mental health symptoms.
Temperature Dependence of the Pre-Chromatographic ‘Lawrence’ Method for Bivalves Contaminated with Paralytic Shellfish Poisoning Toxins
Authors: Vale Paulo 
Published: September 2024

AbstractSaxitoxins are potent neurotoxins originating the acute human neurological syndrome of paralytic shellfish poisoning (PSP) via bivalve vectors. The official testing method in the European Union, commonly known as the ‘Lawrence method’, involves pre-column oxidation steps. The Portuguese monitoring adopted the hydrogen peroxide oxidation screening approach for bivalves contaminated with Gymnodinium catenatum toxins, which can quantify chromatographically at once 6 out of 10 analogues commonly found in bivalves. Seasonal fluctuation in the fluorescence yield of calibration curves was observed across years in a consistent manner. It correlated with fluctuations in average monthly air temperature in Lisbon, highlighting the importance of recording the room temperature during the oxidation steps as a matter of routine practice. Incubation experiments also showed an increase in fluorescence yield with temperature, more pronounced for the 11-hydroxysulphate analogues (dcGTX2 + 3, C1 + 2, GTX2 + 3) than for the 11-H toxins (dcSTX, GTX5[B1], STX). Temperature can be exploited to increase fluorescence yield, assisting in spectral confirmation, but must not exceed 40–50 °C to avoid toxin decomposition or production of extra oxidation products.
Aesthetics or Communication?: Social Semiotic Traits of Structured Forms in Studies of “Animal Beauty”
Authors: Ongstad Sigmund 
Published: September 2024

Abstract
The article investigates basic relations between aesthetics and communication based on studies of and discussions about what has been termed “animal beauty”. The concepts beauty, aesthetics, and communication are problematised, starting from utterances’ structured form, which is seen both as the physical basis for as well as one of five key aspects in animal utterances (form, content, act, time, and space). The relational, and thus social semiotic, communicational role of this aspect is searched in different studies leading to two major claims: Firstly, that five corresponding constitutional traits or aspects, aesthetics, epistemology, ethics, temporality, and spatiality collectively form a basis for animals’ evaluation of the subjective value of utterances. The importance of each of them varies depending on what kind of communication (life-genre) they are associated with. Secondly, that aesthetics should be comprehended on four integrated levels, from micro to macro, sign, utterance, life-genre, and life-world. These four levels plus five aspects or components in utterances make up a systemic, social semiotic communicational framework which in turn is applied for inspections of studies studying “beauty”. Methodological challenges applying them are briefly discussed. An overall conclusion is that research on the evolutionary role of animal beauty should treat the aesthetics of utterances as part of the hermeneutic circle, simultaneously as categorial and relational, in other words as a constitutive part of a whole, a semiotic, species-specific socio-communicational system.
National brands versus store brands: retailer fight against national brands to improve store brands via a dynamic discount pricing strategy

Published: September 2024

AbstractToday, there is a lot of competition between competitors in the market of different products. The level of complexity of relationships and behavior of active players in the market has also increased. So that a manufacturer and retailer work together to increase the profit of the supply chain through the sale of products. On the other hand, the retailer and the manufacturer as competitors are competing with each other to sell more of their products. This issue has increased the complexity of the relationship between retailers and manufacturers. This study aims to explore how retailers can strengthen the self-introduced store brand (SB) and resist the pressures of manufacturers by using dynamic discount pricing (DDP) strategy. Numerical examples are proposed to clearly explain the validity and applicability of the model. Based on the managerial insights developed by analyzing the model's results, we evaluated the influences of DDP strategy on the retail prices and demands of national brands (NB) and SB and the profit of the retailer and the manufacturer. We found that discounts on the manufacturer's product by the retailer increase the demand for both NB and SBs. An increase in demand leads to an increase in the profits of manufacturers and retailers. However, the increase in the manufacturer's profit does not compensate for the decrease in his market share. In other words, the introduction of an SB always causes damage to the manufacturer, but the amount of damage depends on various factors. These findings offer manufacturers and retailers useful insights and help them adopt effective marketing strategies.
Reactions of citrinin with amino compounds modelling thermal food processing
Authors: Brückner Lea , Cramer Benedikt , Humpf Hans-Ulrich 
Published: September 2024

AbstractCitrinin (CIT) is a nephrotoxic mycotoxin, produced by several species of Penicillium, Aspergillus, and Monascus. The foodstuffs most frequently contaminated with CIT include cereals, cereal products, and red yeast rice. Studies on the occurrence of CIT in food have shown that the CIT concentrations in processed cereal-based products are generally lower than in unprocessed industry cereal samples. One possible explanation is the reaction of CIT with major food components such as carbohydrates or proteins to form modified CIT. Such modified forms of CIT are then hidden from conventional analyses, but it is possible that they are converted back into the parent mycotoxin during digestion. The aim of this study is therefore to investigate reactions of CIT with food matrix during thermal processes and to gain a deeper understanding of the degradation of CIT during food processing. In this study, we could demonstrate that CIT reacts with amino compounds such as proteins, under typical food processing conditions, leading to modified forms of CIT.

AbstractThis paper examines the integration of generative artificial intelligence (AI) in doctoral writing pedagogy. It explores how AI augments traditional teaching and composition processes, fosters a new paradigm of cognitive engagement and collaborative academic writing, and the broader ethical and social implications of human-AI writing in doctoral writing pedagogy. A community-engaged participatory research methodology was employed within a Doctor of Healthcare Administration program. Data were collected through discussion board messages, self-assessment papers, student reflections, and a focus group interview, and analyzed using thematic analysis. The research unearthed a hybrid human-AI writing process characterized by dynamic brainstorming, continuous negotiation of meaning, and comparative evaluation. These practices enhanced students' cognitive and metacognitive engagement, confidence, and learner agency, signifying a shift toward a collaborative approach to academic writing. The findings highlight the need for academic institutions to adapt policies and curricula to incorporate AI technologies ethically and responsibly. Emphasis on AI literacy and academic integrity is crucial for preparing graduates for an AI-integrated workforce. This study contributes to the understanding of AI's role in doctoral education, specifically doctoral writing development, presenting a novel perspective on the synergistic collaboration between students and AI in academic writing and its implications for institutional policies and writing pedagogy.
