Dissolved organic matter released from beach wrack is source-specific and molecularly highly diverse
Authors: Waska Hannelore , Banko-Kubis Hanne M. 
Published: July 2024

AbstractBeach wrack is an important supplier of nutrients and organic matter to sandy beach ecosystems and underlying subterranean estuaries (STEs), producing metabolic hotspots in these otherwise organic carbon- and nutrient-poor environments. To assess the impact of beach wrack type (e.g., marine, terrestrial, plant, animal) and environmental settings (e.g., tidal inundation, precipitation, and solar irradiation) on nutrient and dissolved organic matter (DOM) release, a series of leaching experiments was conducted. Quantities of leached nutrients and dissolved organic carbon (DOC) were determined, and DOM molecular composition was investigated using Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). Millimolar—to molar amounts of DOC and dissolved nitrogen were released from the beach cast per kg dry weight, with type of wrack and leaching medium (fresh- vs. saltwater) exerting the biggest influences. Exemplary for animal cast, jellyfish leached up to two 100-fold more, mostly organic, nitrogen compared to all other beach wrack types. FT-ICR-MS data of solid-phase extracted DOM indicated that beach wrack releases compounds with putative mono- and oligosaccharide-, amino acid- and vitamin-type molecular formulae, which likely serve as valuable substrate for heterotrophic microorganisms. DOM from the brown seaweed Fucus sp. was more aromatic than seawater DOM and even beach wrack of terrestrial origin, probably from structural components and secondary metabolites such as phlorotannins. We conclude that DOM and nutrient release from beach wrack strongly depends on wrack type and leaching medium, may obscure molecular provenance proxies (e.g., terrestrial indices), and adds a nutritional boost to infiltrating sea- and rainwater which likely impact microbial respiration rates in the STE.
Teacher-child Discourse in Vietnamese Preschool Classrooms: An Exploratory Case Study of Teachers’ Questions and Statements in the Planned Science Activity

Published: July 2024

AbstractThe quality of teacher-child discourse affects children’s development and learning. Our study aims to explore teacher-child discourse during planned science activities (PSAs) in Vietnamese preschools. This research is essential to understanding the reasons behind Vietnamese children’s low level of scientific skills and to exploring the dynamics of discourse in an Asian context. We conducted a case study to describe and understand the teacher-child discourse during PSAs. The study involved eight PSA sessions in four classes of three to four-year-old in Da Nang, Vietnam. We found that teachers tended to make statements more often than ask questions. When they did ask, they preferred using closed questions that did not require much of a response from children. Open questions were used sparingly, even though they are crucial for promoting children’s cognitive thinking and literacy. Teachers also made use of rhetorical questions that did not require any answer. This has led to mostly non-interactive classes where students remain passive learners. To improve the quality of teacher-child discourse, we suggest providing teacher training on encouraging children to participate and asking more engaging questions.
Can China's energy policies achieve the "dual carbon" goal? A multi-dimensional analysis based on policy text tools
Authors: Zhu Yiping , Hu Yang , Zhu Yi 
Published: July 2024

AbstractThe continuous increase in global temperatures and frequency of extreme weather events underscore the urgency of achieving "dual carbon" goals. Systematically examining the textual characteristics of energy policies under the "dual carbon" framework, synthesizing the implementation pathways of "dual carbon" initiatives contribute to enhancing comprehension, execution, and optimisation of these policies. This study selecting 409 energy policies under the "dual carbon" goals issued by the central government, the State Council, and ministries from 1992 to 2022 as samples, using policy econometrics and content analysis methods, external characteristics of energy policies including publication time, publication type, and publication subject were analysed. Multidimensional content analysis was conducted for policy tools, objectives, and participants. The implementation path of the "dual carbon" goals was summarised. The study found that China's energy policy under "dual carbon" target has undergone four development stages before and after the release of the energy policy, and energy policy system has been continuously supplemented and improved. Various energy policy tools, diverse policy participants, and policy objectives are of concern and focus. From the "tool-subject-target" perspective, six paths for the implementation of "double carbon" targets in China's energy field are summarised. The energy policy under the "dual carbon" goal has problems such as lack of laws and regulations, over-use of environmental policy tools, uneven distribution in the internal segmentation of policy tools, insufficient involvement of market players and the public, and insufficient attention to the reform of energy systems and mechanisms and the goal of establishing energy-saving and low-carbon concepts.
Blame and praise: responsibility attribution patterns in decision chains
Authors: Bhatia Deepti , Fischbacher Urs , Hausfeld Jan , Stumpf Regina 
Published: July 2024

AbstractHow do people attribute responsibility when an outcome is not caused by an individual but results from a decision chain involving several people? We study this question in an experiment, in which five voters sequentially decide on how to distribute money between them and five recipients. The recipients can reward or punish each voter, which we use as measures of responsibility attribution. In the aggregate, we find that responsibility is attributed mostly according to the voters’ choices and the pivotality of the decision, but not for being the initial voter. On the individual level, we find substantial heterogeneity with three overall patterns: Little to no responsibility attribution, pivotality-driven, and focus on choices. These patterns are similar when praising voters for good outcomes and blaming voters for bad outcomes.

Privacy’s Sky-High Battle: The Use of Unmanned Aircraft Systems for Law Enforcement in the European Union
Authors: Kurtpınar E. Öykü 
Published: July 2024

AbstractBenefiting from the rapid advancements in Unmanned Aircraft Systems (UAS) technology with enhanced tracking and data collection capabilities, law enforcement authorities re-discovered air as a dimension where state power can be exercised in a more affordable, accessible, and compact way. On the other hand, during law enforcement operations, UAS can collect various types of data that can be personal or sensitive, threatening the right to privacy and data protection of the data subjects. Risks include challenges related to data security, bulk data collection, the diminished transparency and fairness resulting from the inconspicuous nature of UAS, as well as ethical concerns intertwined with privacy and data protection. Upon examination of the legal framework including the General Data Protection Regulation the Law Enforcement Directive, various Aviation rules, and the new proposal for the Artificial Intelligence Act, it becomes apparent that the EU legal framework’s adequacy in safeguarding privacy and data protection against law enforcement use of UAS is context-dependent, varying across use cases. The current framework lacks clarity, leading to arbitrary application and limited protection for data subjects. Enforcement of safeguards is insufficient, and the Aviation Regulations, applicable to law enforcement UAS, require member states' opt-in, which has not occurred as of the authors’ knowledge. The Artificial Intelligence Act addresses UAS operations but focuses on market risks rather than obligations imposed on law enforcement authorities. Consequently, the existing framework is rendered inadequate for medium to high-risk law enforcement operations, leaving individuals vulnerable and insufficiently protected against intrusive UAS surveillance. Rectifying this involves addressing the enforcement gap and making the necessary amendments to relevant regulatory aspects. Additionally, the implementation of specific technical measures and steps to foster effective cooperation among stakeholders in UAS deployment for law enforcement is imperative.
Multi-Encoder Spatio-Temporal Feature Fusion Network for Electric Vehicle Charging Load Prediction
Authors: Chen Yufan , Wang Mengqin , Wei Yanling , Huang Xueliang , Gao Shan 
Published: July 2024

AbstractElectric vehicles (EVs) have been initiated as a preference for decarbonizing road transport. Accurate charging load prediction is essential for the construction of EV charging facilities systematically and for the coordination of EV energy demand with the requisite peak power supply. It is noted that the charging load of EVs exhibits high complexity and randomness due to temporal and spatial uncertainties. Therefore, this paper proposes a SEDformer-based charging road prediction method to capture the spatio-temporal characteristics of charging load data. As a deep learning model, SEDformer comprises multiple encoders and a single decoder. In particular, the proposed model includes a Temporal Encoder Block based on the self-attention mechanism and a Spatial Encoder Block based on the channel attention mechanism with sequence decomposition, followed by an aggregated decoder for information fusion. It is shown that the proposed method outperforms various baseline models on a real-world dataset from Palo Alto, U.S., demonstrating its superiority in addressing spatio-temporal data-driven load forecasting problems.

). The materials were synthesized using the solid-state reaction method. The influence of Eu + 3 ion incorporation on the crystal structure was examined using XRD, which indicated the formation of a cubic phase. Lattice parameter measurements showed excellent agreement with various theoretical models for predicting the lattice constant, with an average error of only 0.20%. UV–visible spectroscopy analysis is utilized to investigate optical characteristics, revealing a decrease in the optical band gap from 2.65 to 2.77 eV post-Eu doping, which is notably lower than the bulk barium titanate value of 3.2 eV. Materials with smaller band gaps are more suited for optoelectronic applications like photodetectors and light-emitting diodes (LEDs). The dielectric response of europium-doped barium titanate was studied across a frequency range of 1 kHz to 2 MHz and a temperature range of 77 to 300 K, showing remarkable stability. The frequency-dependent dielectric analysis revealed that the dielectric constant initially increased with increasing doping concentration, but decreased at higher concentrations. These results suggest that europium-doped barium titanate holds significant promise for future electronic device applications due to its enhanced optical and dielectric properties.
When the Dark Employee Takes an Irrational Turn: Exploring the Intersection of Dark Personality Traits and Work-Related Beliefs
Authors: Čopková Radka 
Published: July 2024

AbstractAn individual’s disposition towards work is influenced by various factors, including cognitive perception of reality. The attitudes individuals hold towards work are not always based on rational thinking and are also influenced by personality traits. Current research findings suggest that personality traits predict irrational beliefs, which in turn lead to different forms of maladjustment. These personality traits, commonly referred to as the Dark Triad, encompass Machiavellianism, narcissism, and psychopathy. These traits exhibit several shared characteristics with workaholism, a condition associated with irrational beliefs pertaining to work performance. This study aimed to explore the associations between irrational beliefs regarding work and the aversive personality traits. The results indicated a positive correlation between Machiavellianism and work-related irrational beliefs, particularly in relation to failure and control. Narcissism exhibited a positive association with co-workers’ approval. Psychopathy demonstrated a significant positive correlation with control and a negative correlation with performance demands. Regression models were employed to explain the variance in work-related irrational beliefs, ranging from 5.4 to 8.3%. This research builds upon previous studies that have examined workaholism, irrational beliefs, and personality traits, mostly Big Five. By linking the Dark Triad to specific irrational beliefs about work, this research contributes to a deeper understanding of how detrimental personality traits can influence workplace dynamics and individual work attitudes, extending beyond the broader categories typically studied under the Big Five personality traits. This insight is valuable for developing targeted interventions to address and mitigate the impact of these traits in professional settings.

Abstract
The 0.1 M TODGA + 0.2 M DOHyA/n-DD phase was irradiated to various absorbed dose levels and the extraction behaviour of nitric acid and Nd(III) in the irradiated organic phases were studied. The organic phase was then subjected to dynamic light scattering studies to understand the aggregation behaviour in the organic phase. The results showed that the polar degradation products formed in the organic phase decreased the aggregation, while the higher homologue of n-DD enhanced aggregation.
Vision transformer and CNN-based skin lesion analysis: classification of monkeypox
Authors: Yolcu Oztel Gozde 
Published: July 2024

AbstractMonkeypox is an important health problem. Rapid diagnosis of monkeypox skin lesions and emergency isolation when necessary is essential. Also, some skin lesions, such as melanoma, can be fatal and must be rapidly distinguished. However, in some cases, it is difficult to distinguish the lesions visually. Methods such as dermoscopy, high-resolution ultrasound imaging, etc. can be used for better observation. But these methods are often based on qualitative analysis, subjective and time-consuming. Therefore, in this study, a quantitative and objective classification tool has been developed to assist dermatologists and scientists. The proposed system classifies seven skin lesions, including monkeypox. A popular approach Vision Transformer and some popular deep learning convolutional networks have been trained with the transfer learning approach and all results have been compared. Then, the models that show the best accuracy score have been combined to make the final prediction using bagging-ensemble learning. The proposed ensemble-based system produced 81.91% Accuracy, 65.94% Jaccard, 87.16% Precision, 74.12% Recall, and 78.16% Fscore values. In terms of different criteria metrics, the system produced competitive or even better results than the literature.
Distribution Clearance: Significance and Underlying Mechanisms
Authors: Weiss Michael 
Published: July 2024

Abstract
Purpose
Evaluation of distribution kinetics is a neglected aspect of pharmacokinetics. This study examines the utility of the model-independent parameter whole body distribution clearance (CLD) in this respect.

Methods
Since mammillary compartmental models are widely used, CLD was calculated in terms of parameters of this model for 15 drugs. The underlying distribution processes were explored by assessment of relationships to pharmacokinetic parameters and covariates.

Results
The model-independence of the definition of the parameter CLD allowed a comparison of distributional properties of different drugs and provided physiological insight. Significant changes in CLD were observed as a result of drug-drug interactions, transporter polymorphisms and a diseased state.

Conclusion
Total distribution clearance CLD is a useful parameter to evaluate distribution kinetics of drugs. Its estimation as an adjunct to the model-independent parameters clearance and steady-state volume of distribution is advocated.

AbstractVenous thromboembolism (VTE) is the third most common type of cardiovascular disease. An association between high level of physical activity (PA) and the onset of VTE has been found in some, but not all previous studies. We aim to study the association between PA-level and VTE in a cohort of men with updated data on PA levels at four occasions. We used data from the Uppsala Longitudinal Study of Adult Men (ULSAM) study initiated in 1970, a study of men at age 50 years (n = 2,294 at baseline) examined on leisure time PA by questionnaire and traditional cardiovascular risk factors. Examinations were repeated at ages 60, 70, and 77, and follow-up was completed after a median time of 33 years. Cox regression analysis with hazard ratios (HRs) using updated covariates for PA and risk factors was performed on the association of PA levels with incident VTE, with adjustments for established cardiovascular risk factors (systolic blood pressure, LDL- and HDL-cholesterol, BMI, diabetes, and smoking). Totally 186 men experienced a VTE during follow-up of 68,263 person-years at risk. Individuals with the highest PA level had an increased relative risk of VTE, adjusted HR, 2.22 (95% CI 1.05–4.67), when compared to individuals with the lowest level of PA. In this cohort of men with a follow-up of 27 years, the risk of VTE was increased at the highest PA level. Findings indicate that there could be an increased VTE risk with higher PA level including strenuous activities.

Published: July 2024

AbstractPollutant biomonitoring demands analytical methods to cover a wide range of target compounds, work with minimal sample amounts, and apply least invasive and reproducible sampling procedures. We developed a method to analyse 68 bioaccumulative organic pollutants in three seabird matrices: plasma, liver, and stomach oil, representing different exposure phases. Extraction efficiency was assessed based on recoveries of spiked surrogate samples, then the method was applied to environmental samples collected from Scopoli’s shearwater (Calonectris diomedea). Extraction was performed in an ultrasonic bath, purification with Florisil cartridges (5 g, 20 mL), and analysis by GC–Orbitrap–MS. Quality controls at 5 ng yielded satisfactory recoveries (80–120%) although signal intensification was found for some compounds. The method permitted the detection of 28 targeted pollutants in the environmental samples. The mean sum of organic pollutants was 4.25 ± 4.83 ng/g in plasma, 1634 ± 2990 ng/g in liver, and 233 ± 111 ng/g in stomach oil (all wet weight). Pollutant profiles varied among the matrices, although 4,4′-DDE was the dominant compound overall. This method is useful for pollutant biomonitoring in seabirds and discusses the interest of analysing different matrices.

AbstractPhylloquinon (PK) and menaquinones (MK) are both naturally occurring compounds belonging to vitamin K group. Present study aimed to comprehensively analyze the influence of PK in several models of vascular dysfunction to determine whether PK has vasoprotective properties, similar to those previously described for MK. Effects of PK and MK on endothelial dysfunction were studied in ApoE/LDLR−/− mice in vivo, in the isolated aorta incubated with TNF, and in vascular cells as regard inflammation and cell senescence (including replicative and stress-induced models of senescence). Moreover, the vascular conversion of exogenous vitamins to endogenous MK-4 was analyzed. PK, as well as MK, given for 8 weeks in diet (10 mg/kg) resulted in comparable improvement in endothelial function in the ApoE/LDLR−/− mice. Similarly, PK and MK prevented TNF-induced impairment of endothelium-dependent vasorelaxation in the isolated aorta. In in vitro studies in endothelial and vascular smooth muscle cells, we identified that both PK and MK displayed anti-senescence effects via decreasing DNA damage while in endothelial cells anti-inflammatory activity was ascribed to the modulation of NFκB activation. The activity of PK and MK was comparable in terms of their effect on senescence and inflammation. Presence of endogenous synthesis of MK-4 from PK in aorta and endothelial and smooth muscle cells suggests a possible involvement of MK in vascular effects of PK. In conclusion, PK and MK display comparable vasoprotective effects, which may be ascribed, at least in part, to the inhibition of cell senescence and inflammation. The vasoprotective effect of PK in the vessel wall can be related to the direct effects of PK, as well as to the action of MK formed from PK in the vascular wall.
