AI-Related Threats to Information Sovereignty and Challenges for Research Ethics
Authors: Skulmowski Alexander 
Published: September 2024

AbstractUnnoticed by most, some technology corporations have changed their terms of service to allow user data to be transferred to clouds and even to be used to train artificial intelligence systems. As a result of these developments, remote data collection may in many cases become impossible to be conducted anonymously. Researchers need to react by reconsidering their mode of data collection, raising awareness, and expanding informed consent to ensure information sovereignty. Considerations for data sharing are discussed.
Software product line testing: a systematic literature review
Authors: Agh Halimeh , Azamnouri Aidin , Wagner Stefan 
Published: September 2024

AbstractA Software Product Line (SPL) is a software development paradigm in which a family of software products shares a set of core assets. Testing has a vital role in both single-system development and SPL development in identifying potential faults by examining the behavior of a product or products, but it is especially challenging in SPL. There have been many research contributions in the SPL testing field; therefore, assessing the current state of research and practice is necessary to understand the progress in testing practices and to identify the gap between required techniques and existing approaches. This paper aims to survey existing research on SPL testing to provide researchers and practitioners with up-to-date evidence and issues that enable further development of the field. To this end, we conducted a Systematic Literature Review (SLR) with seven research questions in which we identified and analyzed 118 studies dating from 2003 to 2022. The results indicate that the literature proposes many techniques for specific aspects (e.g., controlling cost/effort in SPL testing); however, other elements (e.g., regression testing and non-functional testing) still need to be covered by existing research. Furthermore, most approaches are evaluated by only one empirical method, most of which are academic evaluations. This may jeopardize the adoption of approaches in industry. The results of this study can help identify gaps in SPL testing since specific points of SPL Engineering still need to be addressed entirely.
Novel and classical methods similarly describe variation in territory size among males in Neotropical poison frogs with contrasting reproductive and behavioral strategies

Published: September 2024

AbstractTerritoriality is a form of social dominance concerning the use of space that ensures the territory owner primary access to critical resources. The territory is defended with visual displays, advertisement calls, physical attacks, or chemical signals. The territory is frequently estimated by mapping locations where an animal is observed engaging in territorial behavior or by tracking. However, these approaches may over- or underestimate the areas defended. Thus, the use of approaches explicitly determining defended areas is critical to properly characterize the territory. Intrusion experiments can elicit a response in territory holders, allowing one to characterize their aggressive responses; however, the aggressive response depends on the species. We describe an approach to experimentally estimate the territory size using playback experiments in a species that exhibits a stereotypical phonotactic response: the nurse frog, Allobates aff. trilineatus and develop a new behavioral index that allows assessing territory size in response to playbacks for a species with non-stereotyped phonotactic response: the endangered Lehmann’s poison frog, Oophaga lehmanni. We conducted 772 playback experiments on 18 males of A. aff. trilineatus, and 222 on nine males of O. lehmanni. We analyzed the results of playback experiments with three different area estimators regularly used to estimate space use and evaluated whether these estimates are correlated. The shape and size of territories varied among individuals and estimators in both species. Although we found that the absolute size of the territory depends on the method used, estimates were strongly correlated, meaning that different estimators similarly describe variation in territory size among males. Choosing an analysis method may not be particularly important for studying the characteristics of territoriality over space and time but using a systematic and standardized experimental approach that also incorporates the particularities of the aggressive response of each species is essential to understand the evolution of space use by poison frogs and other territorial species.
Anisotropic thermoelectric power in single crystalline Mg1-xAlxB2 compounds
Authors: Toliński Tomasz , Oganisian Karen , Karpiński Janusz , Rogacki Krzysztof 
Published: September 2024

AbstractThe thermoelectric power of single crystalline Mg1−xAlxB2 compounds is measured and analyzed along the main crystallographic directions (ab-plane and c-axis direction). It is shown that the classical model of thermoelectric power with phonon drag and diffusion terms provides satisfactory explanation of the temperature dependence of the Seebeck parameter S(T). Agreement of S(T) with the study of resistivity is achieved with some variation of the Debye temperature being a model-sensitive parameter. Presence of positive and negative charge carriers is observed and competing contributions of the π and σ bands are discussed.
Diatom dynamics during the last six centuries in Lake Odensjön: a new varved sediment record from southern Sweden

Published: September 2024

Abstract
Varved lake sediments offer valuable insight into past environmental conditions with high temporal resolution and precise chronological control. A combination of diatom and geochemical analyses of the recently deposited sediments of Odensjön, a small dimictic lake in southern Sweden, shows alternating light and dark laminae composed of greater amounts of biogenic silica and organic matter, respectively. As confirmed by independent radiometric dating and Pb pollution data, and supported by scanning electron microscopy of individual laminae, these features represent ongoing deposition of biogenic varves. Corresponding diatom and geochemical data obtained from a 92-cm long freeze core provide evidence of substantial lake-ecosystem dynamics during the last six centuries, related mainly to variations in light penetration and wind shear driven by human-induced changes in catchment vegetation. The diatom assemblage of Odensjön’s varved sediments is dominated by planktonic species, primarily Asterionella formosa, Fragilaria saxoplanktonica and Discostella lacuskarluki during periods of forest cover, while increased catchment openness from the mid-1500s to the late 1800s led to increased abundance of Lindavia comensis. Long-term variations in climate and land use, mediated through changing length of the ice-cover season and nutrient input, respectively, probably contributed to the observed trends, as well as to variations in the appearance and visibility of the varve record across the sampled sediment sequence. Odensjön represents the southernmost varved sediment record in Fennoscandia documented to date, offering potential to study the effects of various types of external forcing on its sensitive lacustrine ecosystem since the Late Weichselian deglaciation. In the present study, we investigated the possibility of assessing the local impacts of two major, historically documented volcanic events, Laki 1783–84 and Tambora 1815, which are known to have affected European societies. Although the mildly alkaline waters of the lake are well buffered and hence relatively resilient to volcanic acid deposition, a minor response to the Laki eruption may be recorded in the diatom stratigraphy.
Theoretical calculation methods of stable bearing capacity for thin-walled shells with corrosion and variable temperature
Authors: Liu Cheng Huijuan , Lacidogna Giuseppe 
Published: September 2024

AbstractThin-wall shells (steel plates, steel cylindrical shells, steel spherical shells, etc.) are widely used in many engineering fields such as construction, machinery, chemical industry, navigation, and aviation because of their light weight and high strength. Their failure modes under static pressure or impact dynamic load are mostly buckling instability, and the failure is very sudden, often causing structural failure or even catastrophic accidents without obvious symptoms. In this framework, the significance of this paper is that it considers the influence of external environment corrosion on steel shells' bearing capacity using plate and shell classical stability theory, and investigates the stable bearing capacity of thin-wall steel shells in view of corrosion impact. By this approach, a theoretical calculating method for the time-varying stable bearing capacity of plate and shell thin-walled steel members under the simultaneous action of corrosion and temperature changes is obtained, providing a useful theory for complex engineering practices such as corrosion and temperature changes, including fire actions. Noted that for this method with no analytical solution found, its numerical solutions are given in the appendixes.
Exprimer la dynamique spatiale par l’utilisation de l’adjectif grave et ses équivalents polonais dans les textes de loi
Authors: Śliwa Dorota 
Published: September 2024

AbstractStarting from the observation that the construction of vague reference in legal texts is intended by the legislator, we examine the intensifier adjective grave linked to linguistic vagueness. The aim is to define the meanings of grave and the role of the noun it qualifies, and to identify Polish equivalents in comparable and parallel legal texts. After mentioning studies on vagueness and vague reference, we analyse definitions that indicate two meanings: ‘importance’ and ‘consequence. The ‘cause-consequence’ relationship becomes central to the study of the categories of intensifiable nouns and grave meanings. The Polish equivalents prove that it is polysemous and that the place of the N in the logical relation must be taken into account.

Published: September 2024

AbstractThe growth of cities is an unstoppable phenomenon that began in the last century and will undoubtedly be one of the challenges of the current century. It is not only a question of urbanization; its implications and consequences extend to the economy, society, culture and the environment. The capacity of cities as engines of change and progress cannot be questioned, and its consequences will alter the lives of their citizens, who will search, in a more liquid world, for the best places to live. Therefore, this study aims to examine the influence of perception of urban quality (PUQ) and social trust and security (STS) on the life satisfaction (LS) of European citizens to find out if these variables are essential for the population living in Europe. The data were selected from the European Urban Audit survey, which covers 40,597 people living in 80 European cities. The analysis in this study is carried out at the city level. The partial least squares structural equation modelling approach was applied to verify the hypotheses. The findings reveal a positive correlation between PUQ and STS with LS, with STS being a mediator between PUQ and LS. These results underline that improving the perception of the urban environment can significantly increase well-being, contributing more than 70% to citizens' life satisfaction. This multidisciplinary analysis highlights the importance of considering various urban dimensions in planning and public policies to foster prosperous and satisfactory urban development.
Revolutionizing Waste Management: Solidification of Landfill Leachates Using Alkali-Activated Slag
Authors: Sithole Thandiwe , Jobodwana Lisakhanya , Magedi Felicia 
Published: September 2024

AbstractLandfill leachate is a highly hazardous effluent characterized by a high concentration of recalcitrant pollutants, presenting a significant environmental challenge. This study investigated the solidification of landfill leachate contaminants using sodium hydroxide-activated Granulated Blast Furnace Slag (GBFS). The stability of the resulting geopolymer was evaluated through unconfined compressive strength and leaching tests. Optimal curing conditions were identified as 7 days at a sodium hydroxide concentration of 12 M, achieving an unconfined compressive strength of 45.738 MPa at a liquid-to-solid ratio of 15%. A linear relationship was observed between the liquid-to-solid ratio and flow workability, with maximum flow workability evidenced by an average diameter of 242 mm at a liquid-to-solid ratio of 0.25. However, a minimum liquid-to-solid ratio of 0.15 was necessary to obtain a workable mortar. The produced geopolymers were characterized using X-ray Fluorescence (XRF) for mineralogical analysis, Scanning Electron Microscopy (SEM) for morphological examination, and the Toxicity Characteristic Leaching Procedure (TCLP) for leaching tests. The findings demonstrated the successful solidification of landfill leachate using GBFS geopolymer. The leachability tests revealed that the geopolymer did not release metals in concentrations exceeding the allowable limits set by the United States Environmental Protection Agency (USEPA), indicating effective encapsulation of the pollutants within the geopolymer matrix. Furthermore, the resultant geopolymer brick is eco-sustainable and can be classified as a green construction material.
The roles that students’ ethnicity and achievement levels play in teachers’ choice of learning materials in online teaching: evidence from two experimental studies
Authors: Schlag Sabine , Glock Sabine 
Published: September 2024

AbstractResearch has shown that, in general, students are treated differently on the basis of their achievement levels and ethnicity. Such differential treatment might also result in the administration of different learning materials, and so far, not much is known about how teachers choose these materials for different students. In two vignette studies, we investigated which student factors influence teachers’ choice of materials. In Study 1, preservice teachers were asked to choose between an easy or difficult instructional video with the same content in response to vignettes that differed by students’ ethnic minority or majority background. In Study 2, preservice teachers could choose between text or video materials with the same content. The student descriptions varied systematically in achievement (high vs. low) and ethnic background (minority vs. majority). The results of Study 1 showed that ethnic minority background students were significantly more often given the easy video than ethnic majority background students. In Study 2, the results showed that student achievement was the crucial factor. Low-achieving students were given the video significantly more often, whereas high-achieving students were more often given the text. Both studies provide initial insights into how teachers’ material choice might be influenced by student characteristics.
How can the Social Family Climate Contribute to Emotional Intelligence in Preventing Suicidal Ideation and Promoting Life Satisfaction Among Adolescents?
Authors: Peláez-Fernández María Angeles , Mérida-López Sergio , Yudes Carolina , Extremera Natalio 
Published: September 2024

AbstractWhile findings have documented the association between emotional intelligence, life satisfaction, and suicidal ideation among adolescents, few studies have investigated the moderating effect of family climate on the association. This study examined the moderating effect of family cohesion, expressiveness, and conflict on the relationships between emotional intelligence, life satisfaction, and suicidal ideation among Spanish adolescents. A total of 2,722 adolescents aged 12 to 18 (Mage = 14.11, SD = 1.42, 52.8% girls) formed the sample. The interaction effects were significant, with family conflict mitigating the effects of emotional intelligence on life satisfaction, and family cohesion and expressiveness strengthening the effects of emotional intelligence on suicidal ideation. These findings provide additional evidence for the protective role of family cohesion and expressiveness in adolescent suicidal ideation, and the harmful role of family conflict in adolescent wellbeing. The results imply that enhancing family cohesion and expressiveness and reducing family conflict may be a promising way to boost the link between emotional intelligence and life satisfaction and to prevent suicidal ideation among adolescents.

Published: September 2024

AbstractLeveillula taurica has until recently been believed to be the causal pathogen of powdery mildew of tomatoes in Mauritius. However, in the year 2022, another powdery mildew species was detected on tomatoes under culture in various tomato growing localities of the island. Based on morphological comparison and molecular analysis, its identity was confirmed as Erysiphe neolycopersici (anam. Pseudoidium neolycopersici). This species has a worldwide distribution causing severe epidemics mainly on greenhouse tomatoes. There is evidence of the rapid spread of this pathogen during 2022–2023 causing serious infection of all tomato cultivars in greenhouse culture in Mauritius. The origin of these infections and its epidemiological consequences are discussed.
Geodiversification: The Evolution of Geodiversity Through Time
Authors: Stojilković Borut , Gray Murray 
Published: September 2024

AbstractGeodiversity has gained significant attention in the last three decades due to various research endeavouring to bridge the gap between geo- and biodiversity. This paper points at yet another parallel between the two disciplines: just as biodiversity expansion (i.e. biodiversification) can be evaluated through time, geodiversity change can also be observed on a timescale and referred to as ‘geodiversification’. The paper firstly reviews the biodiversification definition and some of its major events including the Cambrian explosion and Great Ordovician Biodiversification Event (GOBE) and suggests that being palaeontological, these can also be regarded as geodiversification events. In relation to that, the paper defines geodiversification and provides examples of important geodiversification events in the Earth’s history and some local-scale examples. The results show that major biodiversification events can occur due to the evolution of geodiversity.
A Study on Microstructural Evolution and Corrosion Behavior of Ti36-Al16-V16-Fe16-Cr16 High-Entropy Alloy Fabricated via Spark Plasma Sintering Technology
Authors: Uyor Uwa O. , Popoola Abimbola P. I. , Popoola Olawale M. 
Published: September 2024

AbstractThis study focused on the synthesis of Ti36-Al16-V16-Fe16-Cr16 high-entropy alloys (HEAs) through spark plasma sintering to ascertain their corrosion resistance performance. Varied sintering temperatures, ranging from 700 to 1100 °C were employed to discern their impact on the alloy's characteristics. The fabricated HEAs underwent characterization using scanning electron microscopy and X-ray diffraction. A potentiodynamic polarization measurement was employed to compare the electrochemical properties of HEAs sintered at different temperatures in sulfuric and chloride aggressive media. The study outcomes indicate that the HEA sintered at 1000 °C exhibited superior corrosion resistance compared to other HEAs at other temperatures. This study contributes valuable insights into the nuanced relationship between sintering temperature, microstructure, and corrosion resistance of Ti36-Al16-V16-Fe16-Cr16 HEAs.

Abstract
Objectives
The COVID-19 pandemic has brought substantial mental health challenges as well as significant changes in the delivery of clinical care and interventions, such as switching from traditional face-to-face to online mode. This study aimed to compare the effectiveness and the course experience of a video-conferencing mindfulness-based intervention (MBI) with that delivered face-to-face.

Method
Schoolteachers (N = 170) were randomly assigned to face-to-face group (n = 94) and video-conferencing group (n = 76) for an 8-week MBI. The schoolteachers’ well-being, including psychological distress, insomnia, perceived stress, mindfulness, positive and negative affect, and life satisfaction, was measured before and after the MBI. Attendance, treatment fidelity, home practice compliance, and program acceptability were collected after the MBI. Qualitative feedback from the two groups was also collected to explore the differences in participants’ subjective experiences.

Results
Both face-to-face and video-conferencing formats of MBI resulted in better general mental health, more positive affect, and higher life satisfaction, as well as significantly lower levels of insomnia, stress, and negative affect. Observed improvement was comparable between face-to-face and video-conferencing MBI. The two groups also showed comparable adherence, intervention fidelity, and program acceptability. Qualitative results showed that while video-conferencing MBI might be weaker in group process, it provided better accessibility for participants.

Conclusions
This study supported the effectiveness and feasibility of video-conferencing MBIs, which are highly accessible for teachers in need of mental health support. Further research exploring enhancements to the group process in video-conferencing MBIs may further improve the effectiveness of online programs.
