Modelling Concept Drift in Dynamic Data Streams for Recommender Systems

Recommendation systems play a crucial role in modern e-commerce and streaming services. However, the limited availability of public datasets hampers the rapid development of more efficient and accurate recommendation algorithms within the research community. This work introduces a stream-based data generator designed to generate user preferences for a set of items while accommodating progressive changes in user preferences. The underlying principle involves using user/item embeddings to derive preferences by exploring the proximity of these embeddings. Whether randomly generated or learned from a real finite data stream, these embeddings serve as the basis for generating new preferences. We investigate how this fundamental model can adapt to shifts in user behavior over time; in our framework, changes correspond to alterations in the structure of the tripartite graph, reflecting modifications in the underlying embeddings. Through an analysis of real-life data streams, we demonstrate that the proposed model is effective in capturing actual preferences and the changes that they can exhibit over time. Thus, we characterize these changes and develop a generalized method capable of simulating realistic data, thereby generating streams with similar yet controllable drift dynamics.

Toxicological Effects of Pendimethalin: Behavioral Changes and LC50 Analysis in Cyprinus carpio

The pre-emergent herbicide pendimethalin is a selective dinitroaniline compound that interferes with the production of microtubules, potentially contaminating groundwater. The current investigation sought to ascertain the acute toxicity levels and behavioral effects of pendimethalin (30% EC) on Cyprinus carpio. Finney's probit bioassay method estimated the lethal toxicity LC50 values for commercial-grade herbicide pendimethalin on C. carpio. This method entails fitting the data collected from experiments to a probit model, which converts the results obtained (such as mortality rates) into a normal distribution scale. It is a useful tool in toxicological research since it enables more precise estimations of the LC50. The lethal toxicity (LC50) values of pendimethalin to C. carpio exposed to 24, 48, 72 and 96-hr were determined to be 2.83µL/L, 2.59µL/L, 2.39µL/L and 2.20µL/L based on the mortality estimations. Pendimethalin-induced behavioral abnormalities in C. carpio were investigated using sublethal concentrations (i.e., 1/15th, 1/10th, and 1/5th of the 96-hour LC50 value) at intervals of 0, 7, 14, 21 and 28 days. Our research observed behavioral shifts such as reduced general activity, reduced foraging behavior, diminished schooling behavior, reduced reflex stimuli, increased opercula movements, irregular movements, mucus secretion, enhanced breathing rates and increased surface air gulping. Our studies showed that pendimethalin can produce both mortality and behavioral alterations in Cyprinus carpio, offering important insights into the pendimethalin fatal and sub-lethal effects. These results highlight how crucial it is to keep an eye on herbicide poisoning in aquatic habitats since even sub-lethal levels can have an effect on fish behavior and the general health of the ecosystem.

Social dilemma of nonpharmaceutical interventions: Determinants of dynamic compliance and behavioral shifts

In fighting infectious diseases posing a global health threat, ranging from influenza to Zika, nonpharmaceutical interventions (NPI), such as social distancing and face covering, remain mitigation measures public health can resort to. However, the success of NPI lies in sufficiently high levels of collective compliance, otherwise giving rise to recurrent infections that are not only driven by pathogen evolution but also changing vigilance in the population. Here, we show that compliance with each NPI measure can be highly dynamic and context-dependent during an ongoing epidemic, where individuals may prefer one to another or even do nothing, leading to intricate temporal switching behavior of NPI adoptions. By characterizing dynamic regimes through the perceived costs of NPI measures and their effectiveness in particular regarding face covering and social distancing, our work offers insights into overcoming barriers in NPI adoptions.

Cash to Contactless: History, Advantages, and Evolution of this Payment Mode in Albania

Cash Payments have traditionally played a significant role in the economy of Albania, as in many countries. Over the decades, Albanian people prefer cash transactions due to cultural factors, financial inclusions, and economic considerations. Decades ago cash was the only way to perform payments, but the evolution of ATM, Debit Card, Credit Cards and other payment options, has played a significant role. During the latest years, the evolution of contactless payments reflects a significant shift in consumer behaviour and technology development. The 2010s saw rapid adaptation, fuelled by the rise of mobile wallets and smartphones, which integrated payment options seamlessly into daily life. In Albanian Banking Industry as contactless payments became more mainstream, advantages such as speed, convenience, security, and paying without any contact, pushed the Albanian customers to embrace this kind of payment, as the fastest choice to perform transactions. Contactless payments in Albania have been gaining traction in recent years, reflecting a broader trend towards digitalization in financial services, threating PIN & Chip payments. Through analyses between different periods, we will try to understand if the contactless payments are the first choice in Albania, and if the financial industries and customers are prepared to these rapid changes.

Behavioral assessment of well-being in the naïve laboratory ferret (Mustela putorius furo)

Domestic ferrets (Mustela putorius furo) are an emerging model species in biomedical research. While behavioral studies are a critical translational tool for evaluating neurologic function in disease models and toxicology studies, there is a lack of ferret-specific behavioral assays and corresponding data on baseline behavior. Play behavior is a promising target for evaluation of psychological well-being, particularly because ferrets engage in solitary and social play well into adulthood. Therefore, in this study, an ethogram of behaviors associated with play, elevated mood, and environmental interaction was developed and applied in experimentally naïve juvenile and young adult male laboratory ferrets (3 and 6 months of age, respectively). Total play/positive affect behavior was significantly greater in adults relative to juveniles, mostly due to increased dook vocalizations. Juveniles also took significantly longer to first exit into the behavior suite than adults. This may be linked to contextual habituation or a developmentally associated shift in anxiety-like behavior. While the frequency of total environmental interaction did not differ by age, juveniles demonstrated increased exploration of objects whereas young adults engaged in more climbing onto/into objects. Overall, this study provides a simple and efficient method to assess psychological well-being and environmental exploration in both juvenile and young adult laboratory ferrets. Future studies are needed to determine the sensitivity of these measures to neurologic injury or disease.

Book Review: Anne-Christin Mittwoch, Nachhaltigkeit und Unternehmensrecht, Schriften zum Unternehmens - und Kapitalmarkrecht 107, TÜBINGEN (MOHR SIEBECK) 2022.

The increasing acknowledgment that economic development is constrained by planetary boundaries, coupled with heightened societal awareness of climate change, places the transition to a sustainable economy at the forefront of today’s global political agendas. International climate policy commitments such as the Paris Climate Agreement and the UN 2030 Agenda for Sustainable Development are shaping the global trajectory of sustainability policy. In the European Union (EU), alongside treaty-based obligations (Art. 3 TEU), the European Green Deal, with its climate neutrality commitment, is laying the groundwork for this transformative change. Recognizing that a sustainable reorientation of the economy necessitates a shift in economic behavior, there is an increasing understanding that companies must play a central role in pursuing sustainability objectives. While public law instruments, such as direct regulatory controls on emissions, have a longstanding tradition of regulating commercial activity, the emerging discourse increasingly emphasizes the role of private law in fostering sustainable business conduct. The monograph "Nachhaltigkeit und Unternehmensrecht" (Sustainability and Company Law), authored by Anne-Christin Mittwoch, substantially contributes to this discussion by exploring to what extent company law is capable of facilitating sustainability objectives.

Creating prosocial environments in prison: Insights from the lived experiences in character-based units

ABSTRACT This study examines the role of Character-Based Units (CBUs) in facilitating rehabilitation among incarcerated populations within a Southeastern U.S. prison system. A sample of 316 participants from three correctional facilities was analyzed to evaluate the impact of CBUs on various behavioral and emotional outcomes. Utilizing a survey methodology, the research assessed shifts in deviant behavior, emotional well-being, and coping mechanisms before and after participants engaged with the CBU environment. The results indicate notable changes in self-reported deviance, with a significant decrease in the prevalence of deviant thoughts and associations with antisocial peers. Furthermore, emotional health metrics revealed that a substantial majority of participants exhibited strong perspective-taking abilities and positive affective responses. Stress levels were reported as low, with a high percentage of individuals demonstrating effective coping skills. These findings suggest that CBUs may effectively promote prosocial behavior and emotional resilience among incarcerated individuals, positioning them as a promising alternative to conventional rehabilitation programs. Future research is encouraged to investigate the long-term effects of CBUs on the overall well-being of those involved over time.

Sustainable practices and household resilience: an empirical analysis of behavior change in times of crises

Understanding sustainability behavior is essential in tackling the global challenge of climate change. The importance of studying sustainability practices and their dynamics grows in light of recent global crises such as the COVID-19 pandemic and the energy crisis following the Ukraine war. These events both challenge and shape individual sustainable practices, offering opportunities for fostering individual sustainable practices and enhancing societal resilience. An online survey was conducted in Germany (n = 571, May 2023) to investigate sustainable behavior dynamics (mobility, energy-saving, and shopping habits) and to identify segments reflecting behavioral shifts. We found relative stability in sustainable mobility choices compared to pre-crisis times, with a tendency towards reduction, as well as an overall increase in energy-saving and sustainable shopping habits. Factor analyses revealed that sustainable mobility behavior (SMB) and sustainable consumer practices (SCP) formed two separate domains. Cluster analyses further identified four segments within each domain, each exhibiting unique behavioral patterns compared to pre-crisis practices. Examining individual variables, adopting more sustainable mobility practices was associated with sociodemographic factors (income, education, and area of living), higher levels of environmental awareness, institutional trust, and increased risk perceptions. Sociodemographic variables had less influence on sustainable consumer practices. Here, higher levels of knowledge, climate change awareness, trust, and risk perceptions played a significant role. Our findings highlight the importance of separately considering behavioral domains in understanding crises-induced changes in sustainability practices. Moreover, it is important to consider specific individual factors and to develop tailored interventions and policies to promote sustainable practices during volatile times.

Machine learning analysis of the effects of COVID-19 on migration patterns

This study investigates the impact of the COVID-19 pandemic on European tourist mobility patterns from 2019 to 2021 by conceptualizing countries as monomers emitting radiation to model and analyze their patterns through the lens of socio-economics and machine learning. By incorporating perturbations into clustering, this work evaluates the stability of mobility flux clustering under variable conditions, offering insights into the dynamics of socio-economic corridors. The results highlight distinct shifts in tourist behavior, with bimodal clustering in 2019 reflecting heterogeneous mobility patterns, whereas unimodal distributions in 2020 and 2021 indicate increased global uniformity, driven by pandemic-induced restrictions and gradual recovery. The PCA and dendrograms of the perturbed clustering reveal that tourist preferences align with GDP, cultural, and linguistic similarities, explaining regional cohesion and fragility. This study demonstrates the fragility of emerging socio-economic corridors like the Red Octopus compared to the resilience of established ones like the Blue Banana. The findings emphasize the importance of targeted policy interventions, such as strengthening transport infrastructure and fostering small and medium-sized enterprises (SMEs), to mitigate disruptions and promote balanced regional development. By integrating perturbations into clustering, this research introduces a strong framework for assessing mobility patterns under realistic variability to enhance economic resilience and anticipate shifts in tourist behavior during global crises.

Disrupted intermodality: Examining adaptation strategies to public transport e-scooter bans in Barcelona

Electric scooters (e-scooters) have changed urban mobility by offering a dynamic solution to the critical “first and last mile” problem, connecting individuals from their homes to public transport and their final destinations. Despite their growing popularity, e-scooters navigate through a landscape of shifting legal frameworks, highlighting the urgency for policies that not only harness their potential but also address their inherent challenges. This study aims to shed light on the intermodal practices and demographics of e-scooters users in Barcelona, explores the potential impacts of regulatory changes on established transport habits, and assesses the adaptability of users to changing transportation options. Through a self-reported survey of 311 private e-scooter users, we find a notable prevalence of young men from lower socioeconomic backgrounds engaging in intermodal travel, primarily for employment purposes. To better understand how e-scooter riders integrate the device in their daily mobility strategies, we introduce the Intermodality Ratio (IR). A Generalized Linear Model (GLM) is then used to identify key demographic, socioeconomic, and geographic predictors of the IR, revealing place of residence as the most significant factor influencing intermodal behavior. Finally, we analyze participants’ anticipated behavioral shifts in response to the upcoming ban using a Multinomial Logistic Regression (MLR) model, which explores the sociodemographic factors affecting the likelihood of adopting alternative transport strategies. These findings contribute to the limited understanding of e-scooter utilization and intermodal practices, particularly within the context of public transit, offering insights into how transport policies can more effectively accommodate emerging mobility solutions.

Social Infrastructure During the COVID-19 Pandemic: Evaluating the Impact of Outdoor Recreation on Pandemic Dynamics in Europe

The COVID-19 pandemic has drastically affected mental and physical well-being, leading to significant changes in daily habits and preferences. Given that pandemics require the tear down of most social ties and interactions to limit their inevitable spread, this study delved into the extent to which social infrastructures have been affected, focusing on behavioral shifts in essential services such as retail, recreation, groceries, pharmacies, public transport, parks and open spaces, workplaces, and residential areas. Notably, while most social infrastructures saw a decline in public usage, parks and open spaces experienced increased visitation despite public health measures aimed at minimizing social interactions. This striking increase in park and open space visitations has captured the interest of this study to observe the impact it had on the trajectory of the COVID-19 pandemic, as well as the underlying causes behind this trend. Since Europe was heavily affected by the pandemic, this study focused specifically on European countries over a two-year period (March 2020 to March 2022), covering the severe period of the pandemic. While parks and open spaces initially showed no direct influence on the pandemic trajectory, when closely observing visitation trends, both increases and declines, opposing insights were revealed. This study found that attempts to reduce park and open space visitation were significantly unsuccessful, leading to substantial increases in both the magnitude and duration of visits once restrictions were eased. This surge in park and open space attendance corresponded to notable spikes in new infections during periods of peak visitation. Therefore, urban planning and public health authorities must prioritize safely accommodating the increased park and open space demand while effectively minimizing virus transmission. This involves considering park sizes and proximity, along with implementing a balanced set of crucial public health strategies to support community well-being and resilience.

The Impact of Russia-Ukraine Conflict on the Sales of Electric Vehicles in China

The Ukraine conflict has had a unique impact on EV sales growth in China, a key market for EV innovation and adoption. This study explores the correlation between geopolitical tensions and the surge in EV sales in China. Utilizing time series analysis methods, this paper assesses EV sales trends before and during the conflict. Coincidentally, the findings suggest that the conflict is driving growth in EV sales, likely due to a combination of factors, including increased awareness of energy security, a shift to sustainable transportation, and government incentives aimed at supporting the domestic EV industry. Quantitative analysis using an ARIMA model reveals that EV sales experienced an estimated increase of approximately 15% within the first six months following the onset of the conflict compared to pre-conflict projections. This significant uptick underscores how external geopolitical events can catalyze shifts in consumer behavior toward more sustainable alternatives. While sales are growing, the study also points to potential challenges such as supply chain disruptions and rising costs that could impact long-term growth. These challenges highlight the complex interplay between global political events and domestic market trends. The findings advise policymakers and industry players to remain vigilant and proactive to ensure continued growth in Chinas EV industry amidst these evolving dynamics.

The Analysis of Factors Influencing Online Shopping Behavior in COVID-19 Pandemic: The Study of Indonesian Millenial Generation

The COVID-19 pandemic has led to significant shifts in consumer behavior, particularly in terms of shopping preferences and behavior, with a marked increase in online shopping. This study aims to re-examine the factors influencing online shopping behavior during the COVID-19 pandemic by integrating the framework of the Theory of Planned Behavior (TPB), the Technology Acceptance Model (TAM), and Cognitive Biases. The study focuses on Indonesian Millennials as the target population. Data analysis is conducted using Structural Equation Modeling-Partial Least Squares (SEM-PLS) with SmartPLS 3.0 software. The results show that cognitive bias, perceived usefulness, perceived ease of use, and subjective norms influence individuals' intentions to shop online. However, attitudes toward use and perceived behavioral control (PBC) do not influence individuals' intentions to shop online. Finally, the results indicate that individuals' intentions to shop online impact actual online shopping behavior. The higher the individual's intention to shop online, the more certain they are to do so during the pandemic

Impact of ambient air pollution on physical activity engagement among university students.

PM2.5 poses significant health risks with prolonged exposure, potentially reducing physical activity levels. This study aims to investigate the impact of ambient PM2.5 levels on physical activity engagement among individuals. The retrospective cross-sectional study involved 423 students from Chiang Mai University residing there between January and August 2023. We used the validated Thai version of the International Physical Activity Questionnaire to assess physical activity intensity during high and low pollution periods. Individuals who engage in at least 150 min of moderate-intensity or 75 min of high-intensity physical activity per week meet the recommended physical activity guidelines. Multiple logistic regression analyzed air pollution's relation to physical activity intensity, and Cochran's Q-test compared activity levels across pollution periods. Recommended physical activity prevalence was 76.36% during high PM2.5 and 71.63% during low PM2.5 periods, it showed higher physical activity during polluted periods (p = 0.049). Individuals' behavior showed a preference for indoor exercise (p < 0.001), consistent PM2.5 level checks (p < 0.001) during high PM2.5 periods. Internal motivation significantly associated with recommended physical activity in both low and high PM2.5 periods (aOR = 2.46, 95% CI = 1.14 - 5.27 and aOR = 4.00, 95% CI = 1.84 - 8.70, respectively). The outdoor exercise significantly associated with the recommended physical activity only during the low PM2.5 period (aOR = 1.72, 95% CI = 1.03 - 2.87). University students showed increased physical activity intensity during high PM2.5 periods, favoring indoor exercise in polluted environments. This behavioral shift highlights environmental pollution's influence on lifestyle choices and cornering on health outcomes. Government and university support is crucial for implementing measures to mitigate PM2.5 pollution, including promoting safe indoor exercise, enhancing pollution control measures, and developing air quality monitoring and warning systems.

Risk avoidance during dispersal: Temporal and behavioral shifts in selection by non-resident eastern wolves (Canis c.f. lycaon)

Dispersal is important for connectivity and persistence of small, disjunct wildlife populations. However, in human-altered landscapes dispersing animals are often more likely than residents to use anthropogenic features that increase mortality risk. As such, quantifying spatial and temporal responses of dispersing animals to anthropogenic features will improve our understanding of the potential for small, isolated populations to expand in human-altered landscapes. The distribution of eastern wolves (Canis c.f. lycaon; a threatened species in Canada) is limited to portions of eastern Canada within and adjacent to the population core in Algonquin Park. Recently, it was found that non-resident eastern wolves dispersing outside of Algonquin Park survive poorly, primarily due to high rates of human-caused mortality. We deployed Global Positioning System collars on 26 non-resident eastern wolves. We evaluated resource selection of dispersing individuals during different movement states to better understand their behavioral responses to anthropogenic landscape features during this critical, but risky period of their life history. Eastern wolves avoided areas with high building density during the day. However, during directed movements outside the winter period, eastern wolves selected areas closer to unpaved roads and areas with higher building densities at night. During winter, eastern wolves selected areas with high building densities at night while displaying tortuous movements. We demonstrate that harvested species may increase and relax avoidance of anthropogenic features at both daily and seasonal timescales. Failing to account for temporal and state-specific variation in resource selection patterns of dispersing animals may underestimate their ability to move through human-altered landscapes.

Cutting the sap: First molecular phylogeny of twig‐girdler longhorn beetles (Coleoptera: Cerambycidae: Lamiinae: Onciderini) suggests shifts in host plant attack behaviours contributed to morphological evolution

AbstractUnderstanding how novel adaptive traits arise, evolve and impact other aspects of an organism's phenotype is a foundational question in evolutionary biology. We explore this by focusing on Onciderini (Coleoptera: Cerambycidae: Lamiinae), a tribe of longhorn beetles commonly referred to as twig girdlers because the females of some species girdle live trees to deposit their eggs. We reconstructed the first time‐calibrated phylogeny of the Onciderini, based on three genetic markers (cytochrome c oxidase subunit 1 ‘cox1’, Wingless ‘Wg’ and carbamoyl‐phosphate synthase domain of the CAD locus ‘CPS’), and used morphometric data, employing multiple models of trait evolution and phylogenetic regressions, to assess whether girdling behaviour predicts head size or head size sexual dimorphism. Our results indicate that onciderines originated c. 49 million years ago ‘Ma’ (95% highest posterior densities ‘HPD’: 44.1–54.57 Ma) and consist of two major lineages, which we formalize as subtribes Hypsiomina and Onciderina. Additionally, our analyses revealed several taxonomic inconsistencies within the tribe, which we rectify by proposing new synonymies, including Jamesia Jekel as a synonym of Hypselomus Perty, Cipriscola Dillon &amp; Dillon of Hypsioma Audinet‐Serville and Psyllotoxus Thomson and Taricanus Thomson as a synonym of Oncideres Lacordaire, and a new combination for Periergates kenjii Nearns &amp; Swift as Oncideres kenjii (Nearns &amp; Swift) comb. nov. Using this new phylogenetic framework, we identified five independent unidirectional origins of girdling behaviour within the tribe. Overall, our results suggest that girdling influences head size evolution in Onciderini, as it is associated with an increase in both male and female head size of girdler species. Despite this, girdling and non‐girdling lineages do not consistently differ in head size sexual dimorphism. This study refines the classification of Onciderini and marks a significant step in understanding the evolutionary dynamics shaping the diversity of twig‐girdler beetles, a group with notable ecological and economic importance.
