Authors: Andriianova Anastasia N. , Petrov Ivan S. , Latypova Lyaysan R. , Mustafin Akhat G.
Published: August 2024

Introduction of a substituent into the aromatic ring of polyaniline (PANI) is one of the most popular methods of polymer modification. In this connection, the photoluminescent properties of a wide range of PANI derivatives have been investigated in the present work: ortho-alkenyl substituted PANI derivatives, with different dopants, copolymers of aniline and its substituted analog. The presented results demonstrate that the modification of PANI by introducing a substituent into the aromatic ring contributes not only to the improvement of solubility but also to the increase of photoluminescence intensity. Comparative analysis of photoluminescence spectra of the investigated series of polymers showed that the presence of a bulk substituent in the aromatic ring of the polymer chain leads to an increase in the luminescence intensity due to steric hindrance.

Published: August 2024

As plastic pollution exists in aquatic ecosystems globally, monitoring its abundance and distribution has become crucial for understanding transport pathways, sources, sinks, and impacts. Riverbanks are accumulation zones for plastic, but the selection of monitoring methods is constrained by research goals, available resources, and site-specific conditions. This diversity in approaches has led to disparate datasets, highlighting the need for standardized monitoring protocols. Here, we study the spatial distribution of plastic at the riverbank scale, quantify the uncertainty of existing riverbank methods, and provide recommendations for improved monitoring based on the balance between uncertainty loss and increase in effort. We measured riverbank plastic abundance at eight Dutch riverbanks, categorizing the items using 108 item categories (River-OSPAR). For every riverbank, an area of 100 by 25 meters was subdivided into five-by-five-meter squares, resulting in 100 individual monitored sub-areas. We found riverbank plastic exhibited high spatial variability, with deposition patterns ranging from parallel to the waterline to clustered, random, or uniform (Moran's I between -0.050 and 0.301). Individual measurements from diverse sampling protocols are 5-49 times less accurate than estimates derived from extensive sampling, highlighting the diminishing impact of specific methods with increased data collection. Lastly, our findings suggest that increasing the sampling area quickly reaches diminishing returns in terms of accuracy. Reducing the sampled area by 80% only increases the uncertainty in estimating the true plastic density by 20%. While standardized protocols are essential for data comparability, a rigid, uniform sampling approach may be less efficient and resource-intensive than a flexible (step-wise) strategy that adapts to local conditions. By demonstrating that extensive sampling can mitigate the differences between unique sampling protocols, this study promotes a shift towards flexible and efficient riverbank plastic monitoring, ultimately accelerating global efforts to combat plastic pollution.
Proteomic variation in the oral secretion of Spodoptera exigua and Spodoptera littoralis larvae in response to different food sources
Authors: García-Marín Elena , Gamir Jordi , Crava Cristina M
Published: August 2024

The Spodoptera genus is defined as the pest-rich genus because it contains some of the most destructive lepidopteran crop pests, characterized by a wide host range. During feeding, the caterpillars release small amounts of oral secretion (OS) onto the wounded leaves. This secretion contains herbivore-induced molecular patterns (HAMPs) that activate the plant defense response, as well as effectors that may inhibit or diminish the plant anti-herbivory response. In this study, we explored the protein components of the OS of two Spodoptera species, Spodoptera exigua and Spodoptera littoralis. We identified 336 and 276 proteins, respectively, with a major role in digestion. Using a label-free quantitative proteomics approach, we investigated changes in protein abundance in the OS of both species after switching from a laboratory artificial diet to detached pepper and tomato leaves. Several proteins, such as various lipases, polycalin and a β-1,3-glucan binding protein, were more abundant in the OS of plant-fed larvae in both species. Conversely, a WD-repeat containing protein significantly decreased upon feeding on plant leaves in both species. Phenotypic plasticity dependent on each Spodoptera-plant combination was observed for several peptidases, potentially related to the need to overcome the effects of proteinase inhibitors differentially produced by the two plant species, and for several REPAT proteins, possibly related to the specific modulation of each Spodoptera-plant interaction. Altogether, our results provide useful information for understanding the interaction of these two polyphagous Spodoptera species with the host plants, and help to identify evolutionary traits that may influence the outcome of herbivory in each of these two related species.
Multi-Tiered Cascading Negative Sampling For Graph Based Recommender System

Published: August 2024

Effective negative sampling strategies can accelerate model convergence, suppress excessive randomness in negative sample generation, and enhance the predictive performance of the recommender systems modeled by implicit feedback. However, existing negative sampling methods face two potential issues: limited utilization of user-item collaborative information and treating user-negative sample interactions as driven by a singular motive, thereby ignoring the user’s multi-tiered, gradually progressive implicit preferences, which leads to low-quality negative sampling. To design negative sampling methods suited to different geometric spaces based on their data characteristics, this paper introduces a novel multi-tiered cascading negative sampling method (Multi-Tiered Cascading Negative Sampling, MTCNS) for Euclidean space graph-based collaborative filtering recommender systems. Specifically, this method processes through two cascading levels, producing high-quality overall negative sample embeddings and negative sample feature representations that embody multi-layered progressive relevance semantics. Furthermore, outside the negative sampling method, a multi-task learning framework constructs a contrastive learning auxiliary task to enhance the main task’s performance. Experiments conducted on three real datasets demonstrate that this method improves metrics such as NDCG@20 and Recall@20 by an average of over 1.5%.
Classifying Synoptic Patterns Driving Tornadic Storms and Associated Spatial Trends in the United States
Authors: Jiang Qin , Dawson Daniel , Li Funing , Chavas Daniel
Published: August 2024

Severe convective storms and tornadoes rank among nature’s most hazardous phenomena, inflicting significant property damage and casualties. Near-surface weather conditions are closely governed by large-scale synoptic patterns. It is crucial to delve into the involved multi-scale associations to understand tornado potential in response to climate change. Using clustering analysis, this study unveils that leading synoptic patterns driving tornadic storms and associated spatial trends are distinguishable across geographic regions in the U.S. Synoptic patterns with intense forcing featured by intense upper-level eddy kinetic energy and a dense distribution of Z500 fields dominate the increasing trend in tornado frequency in the southeast U.S., generating more tornadoes per event. Conversely, the decreasing trend noted in certain regions of the central Great Plains is associated with weak upper-level synoptic forcing. These findings offer an explanation of observational changes in tornado occurrences, suggesting that the physical mechanisms driving those changes differ in different regions.

Published: August 2024

In the reform of medical education, innovative teaching methods are increasingly valued. Integrating design thinking (DT) into basic medical courses is seen as a key approach to fostering students' innovation and practical skills. The "Creative Histology and Embryology Learning Skills Expansion Competition," an interdisciplinary project, aims to explore new teaching models, promote comprehensive student development, and provide a practical example for innovative basic medical education. This study used qualitative research methods to conduct interviews with 15 award-winning students, gathering their learning experiences and feedback. We applied grounded theory to analyze the interview data through three levels of coding (open coding, axial coding, and selective coding) to reveal how DT integration in basic medical courses impacts students' innovation awareness and abilities. Open coding clearly identified the primary experiences and feelings of the students. Axial coding grouped these experiences into key themes, and selective coding developed a theoretical framework to explain these experiences and feelings. The three-level coding revealed that clinical undergraduates participating in the interdisciplinary competition had rich experiences and profound insights, particularly in terms of motivation, preparation, collaboration, and gains. DT is an effective tool for improving medical education, particularly in histology and embryology courses. It significantly enhances students' innovation awareness and abilities. This finding confirmed the effectiveness of DT in medical education and supported the transformation of basic medical education models. Future medical education practices should emphasize the integration of DT to cultivate students with innovation and practical skills. This will promote the reform and development of medical education.

Published: August 2024

Worldwide the quality of motorcycle has undergone revolutionary change over last decade. Technological upgradation, customer demand and road infrastructure has contributed to this revolution. These necessitate higher performance of motorcycle tires as tires being interface between powerful engines and the road. Among the various parameters of motorcycle tire tread performance, dry and wet traction, rolling resistance and mileage, are important as they conform the safety requirement, fuel economy and durability. In general, Oil-extended Styrene Butadiene Rubber (OE-SBR) with high styrene provides better traction and abrasion with little deterioration in rolling resistance properties. In this study, vegetable origin oil extended high styrene (40%) SBR’s were characterized in motorcycle tire tread recipe. The use of vegetable oil results in almost zero polycyclic aromatic (PCA) content and therefore, these OE-SBR’s are environmentally friendly, renewable, and sustainable. SBR grades prepared with vegetable oils were showing less mixing energy (around 10%), better flow behavior (low activation energy by around 5%), lower filler-filler interaction (lower Payne effect by more than 25%) and lower tanδ@60°C (around 5%) as compared to petroleum oil.

Published: August 2024

In this study, a finite-time adaptive prescribed performance control scheme is investigated for multi-input multi-output systems with input friction and backlash. The novel fixed-time neuro-disturbance observer (FTNDO) and fixed-time command filter are constructed to ensure fast response of the controlled systems with settling time being determined regardless of initial states. The uncertainties caused by unknown smooth functions are handled by neural network approximators, then input friction and system disturbances are accurately compensated by FTNDO. Meanwhile, the employed fixed-time command filter is utilized to avoid repeated differentiation of virtual control signals during controller design. In particular, prescribed convergence of tracking errors for multi-input multi-output nonlinear system is ensured by finite-time performance function. Finally, simulation and experiment results demonstrate the feasibility and effectiveness of the proposed control strategy.
A simple method to create mineral mounts in thin section for teaching optical mineralogy
Authors: Kohn Matthew J.
Published: August 2024

Mineral separates mounted in thin section help introduce mineralogy students to concepts of relief, color, pleochroism, and birefringence and serve as reference materials both for research and teaching. Here, a simple method is described to produce materials that can be sent to thin section manufacturers to construct sets of mineral mounts. The method is relatively inexpensive, requires only simple equipment and few skills, and allows mounting of multiple minerals (easily 10–20) in a single thin section. The key to the method is to create first a slurry of 500–1000 mg of each crushed mineral plus ∼300 mg (500 μL) of epoxy and use a microspoon spatula to spoon each slurry into a 4 cm long tube made from 6 mm (or ¼″) diameter, standard wall, glass tubing. After epoxy sets, the 4 cm long tubes can be bundled together and shipped to thin section makers, who can set the bundles in epoxy (ends down) and make 10 or more duplicate sections. Photomicrographs are presented for selected mineral reference slides produced by this method, along with detailed instructions on how to create them. These methods allow both randomly oriented mineral separates and oriented crystals to illustrate isotropic appearance in quartz and reverse pleochroism in tourmaline.
The impact of financial regulations on bank lending in emerging economies in Sub-Saharan Africa
Authors: Freddy Aliamutu Kansilembo , Sthembiso Msomi Thabiso
Published: August 2024

The aim of this study is to investigate the impact of financial regulations on bank lending in emerging economies in Sub-Saharan Africa. The dynamic system-generalized method of measures (GMM) is used to address difficulties such as unexplained periods and nation-specific implications, besides the endogeneity of the variables in question. Spanning from 2012 to 2022, the research used data from 80 banks in 20 sub-Saharan African nations. The findings show that expansive financial regulation, which includes a boost in the amount of cash in circulation, induces bank lending. At the same time, restrictive financial regulations, with the value as an improvement in interest rates by central banks, lead to credit contractions, albeit with little impact because of the attainable poverty of banking sectors, organizational limitations, bank-focused attention, and additional system rigidity typical of developing nations, which compromises the efficiency of the system. Other characteristics that substantially impact bank lending routes include capital sufficiency ratios and the scale of economic activity. Sub-Saharan African countries may boost the efficiency of financial regulations propagation on bank lending by making better use of the transfer process of fluctuations in cash supplies and interest rates.

Authors: Babarinde Gbenga Festus , Adegoke Adewusi Olusegun , Idera Abdulmajeed Tajudeen , Hassan Haziel Yusuf
Published: August 2024

Purpose: Past studies have focused on psychological and macroeconomic factors as determinants of investor sentiment. However, the 2019 novel coronavirus disease (COVID-19) outbreak has raised the need to determine whether the pandemic shapes investors' sentiment. Hence, this research aims to examine the role of COVID-19 in shaping investors' sentiment in the Nigerian capital market.
Methodology: In determining whether COVID-19 matters or not in shaping investor sentiment in the Nigerian capital market, this study applied the Vector Error Correction Model (VECM) and Pearson correlation techniques to the analysis of the weekly time series data on COVID-19 confirmed (positive), discharged and fatal cases and their relationships as well as impacts on the stock (capital) market investors' sentiment in Nigeria for the period 2nd March 2020 to 25th October 2020.
Findings: This study confirms a weak positive relationship between COVID-19 and investors' sentiment in the Nigerian stock market. Furthermore, there is evidence that the discharged and fatal cases of COVID-19 have had significant positive impacts on investors' sentiment in Nigeria in the long run, unlike the positive cases, which have had significant negative impacts. In the short-run, however, COVID-19 positive cases have positive while discharged and fatal cases have negative non-significant effects on stock market investors' sentiment in Nigeria.
Practical Implications: It is therefore concluded that COVID-19 cases are significant determinants of investors' sentiment in the Nigerian stock market, such that the effects of the pandemic are significant in shaping stock market investors' sentiment in the country. It is high time the regulatory authorities and investment community, particularly investors, considered the long-run implications of the current COVID-19 pandemic on their behaviour and decisions.
Originality/Value: This is one of the very few studies in Nigeria that discount the influence of health pandemics such as COVID-19 on the behaviour of investors in the stock market concerning sentiments.
Keywords: Investors Sentiment, COVID-19, Nigerian Stock Exchange, Investment Decision.

Authors: Wahyuni Nining Ika , Sukoharsono Eko Ganis , Roekhudin  , Baridwan Zaki
Published: August 2024

Purpose — This study aims to construct the role of accountants as sustainability score players, namely as providers of information, support,  and guidance in embedding sustainable business practices in MSMEs.
Design/methodology/approach—This study uses a participatory action research (PAR) approach to construct the role of accountants. This approach requires the active participation of participants in each stage of the PAR cycle, starting from planning, action, observation and evaluation, and reflection. Data were collected through observation, interviews, and FGD. The data is processed by thematic analysis after going through the triangulation process to check its validity.
Findings—Accountants can expand their role by acting as sustainability score players through inclusion, providing literacy, and initiating MSMEs to start sustainable business practices. Through this involvement, accountants can realize that they can position themselves as agents of change who can become role models and mediators and facilitate the movement towards sustainable business for the MSMEs they assist.
Practical implications—Accountants must develop a new habitus that shows they can contribute significantly to realizing sustainable development goals. One habitus is getting used to being involved with the community, especially with MSMEs. “Engage” represents the ability of accountants to actively participate in any embedded sustainability efforts.
Originality/value—The gap between value and action in sustainability accounting research shows no relationship between values derived from existing theory and practical action. This research fills this gap by using an action research approach and involving educator accountants to determine what actions need to be taken to contribute to achieving sustainable development goals.

Published: August 2024

Purpose—This paper aims to explore the emergent discourse of ethics audit and advance the relevance and importance of ethics audit as an effective way of maintaining an ethical climate in Indonesian government organizations.
 Design/Methodology/Approach—This study uses a qualitative approach with Constructivism-Grounded Theory (CGT) analysis to gather field data and find, explore, and formulate findings. CGT is used because the conceptual foundation regarding ethics audit is still developing.
 Findings—The findings obtained are that the ethics audit proposed in this study is significantly relevant to creating a better ethical climate in government organizations in Indonesia. The relevance involves an analysis of 3 perspectives, namely the micro, meso, and macro levels. The ethics audit model is proposed to provide a design for action in mitigating ethics violations, a framework to achieve good government governance, and a strategy for governing integrated continuous auditing.
Practical Implication—In a situation where the issue of public officials' ethics is being seriously highlighted in society, this study promotes the importance of ethics audits to government organizations. It is hoped that ethics audits will be legitimized as annual practices like the predecessor audits that already exist.
 Originality/Value—This study fills the void of the limited discourse on ethics audits in Indonesia. Findings from this research raise the government’s awareness to be more serious about ethics through ethics audits.
