Opis: In this study, we propose an integrative approach to Small Talk by bringing together routine and ritual, and also by approaching Small Talk through the lens of ritual, speech acts and discourse. Routine manifestations of Small Talk include banal phatic interaction, such as weather talk which follows conventionalised patterns, has limited bonding ca pacity and no deeper meaning. Ritual Small Talk, on the other hand, refers to phatic interaction which also follows conventionalised patterns but has a deeper purpose and meaning, and has a more lasting bonding capacity. We analyse a corpus featuring shop talk in a rural Chinese town, hence filling a knowledge since Small Talk in rural settings has been understudied. We conduct a bipartite analysis, i.e. we first consider how in teractions in our corpus tend to be opened and closed, and then we analyse our data through Small Talk themes. Our analysis shows that in Chinese rural shops routines do not simply dissolve when the participants become more familiar, but rather they transform into ritual. This finding shows that Small Talk in the setting studied operates differently from what has been observed in urbanised contexts.

Opis: Our study investigates polyphenol-protein interactions, analyzing their structural diversity and dynamic behavior. Analysis of the entire Protein Data Bank reveals diverse polyphenolic structures, engaging in various noncovalent interactions with proteins. Interactions observed across crystal structures among diverse polyphenolic classes reveal similarities, underscoring consistent patterns across a spectrum of structural motifs. On the other hand, molecular dynamics (MD) simulations of polyphenol-protein complexes unveil dynamic binding patterns, highlighting the influx of water molecules into the binding site and underscoring limitations of static crystal structures. Water-mediated interactions emerge as crucial in polyphenol-protein binding, leading to variable binding patterns observed in MD simulations. Comparison of high- and low-resolution crystal structures as starting points for MD simulations demonstrates their robustness, exhibiting consistent dynamics regardless of the quality of the initial structural data. Additionally, the impact of glycosylation on polyphenol binding is explored, revealing its role in modulating interactions with proteins. In contrast to synthetic drugs, polyphenol binding seems to exhibit heightened flexibility, driven by dynamic water-mediated interactions, which may also facilitate their promiscuous binding. Comprehensive dynamic studies are, therefore essential to understand polyphenol-protein recognition mechanisms. Overall, our study provides novel insights into polyphenol-protein interactions, informing future research for harnessing polyphenolic therapeutic potential through rational drug design.

Opis: Higher-order interactions shape collective dynamics, but how they affect transitions between different states in swarmalator systems is yet to be determined. To that effect, we here study an analytically tractable swarmalator model that incorporates both pairwise and higher-order interactions, resulting in four distinct collective states: async, phase wave, mixed, and sync states. We show that even a minute fraction of higher-order interactions induces abrupt transitions from the async state to the phase wave and the sync state. We also show that higher-order interactions facilitate an abrupt transition from the phase wave to the sync state bypassing the intermediate mixed state. Moreover, elevated levels of higher-order interactions can sustain the presence of phase wave and sync state, even when pairwise interactions lean towards repulsion. The insights gained from these findings unveil self-organizing processes that hold the potential to explain sudden transitions between various collective states in numerous real-world systems.

Opis: Purpose: This paper aims to define hybrid reality (HyR) as an ongoing process in which artificial intelligence (AI) technology is gradually introduced as an active stakeholder by using reasoning to execute real-life activities. Also, to examine the implications of social responsibility (SR) concepts as featured in the HyR underlying common framework to progress towards the redefinition of global society. Design/methodology/approach: A combination of systemic tools is used to examine and assess the development of HyR. The research is based on evolutionary and learning concepts, leading to the new meta-system development. It also builds upon the viable system model and AI, invoking SR as a conceptual framework. The research is conducted by using a new approach: using system dynamics based interactions modelling, the following two models have been proposed. The state-of-the-art HyR interactions model, examined using SR concepts; and a SR concept-based HyR model, examined using a smart vehicle case. Findings: In the HyR model, interaction asymmetry between stakeholders is identified, possibly leading to pathological behaviour and AI technology learning corruption. To resolve these asymmetry issues, an interaction model based on SR concepts is proposed and examined on the example of an autonomous vehicle transport service. The examination results display significant changes in the conceptual understanding of transport services, their utilisation and data-sharing concepts. Research limitations/implications: As the research proposal is theoretical in nature, the projection may not display a fully holistic perspective and can/should be complemented with empirical research results. Practical implications: For researchers, HyR provides a new paradigm and can thereby articulate potential research frameworks. HyR designers can recognise projected development paths and the resources required for the implication of SR concepts. Individuals and organisations should be aware of their not necessarily passive role in HyR and can therefore use the necessary social force to activate their status. Originality/value: For the first time, to the best of the author’s knowledge, the term HyR is openly elaborated and systemically examined by invoking concepts of SR. The proposed model provides an overview of the current and potential states of HyR and examines the gap between them.

Opis: Weaning involves mixing of unfamiliar litters and is accompanied by an outbreak of aggression, which is usually attributed to between-litter (BL) interactions. In the present study, we thus focused on post-weaning agonism (fighting and mounting) between littermates (within-litter, WL). Two litters were weaned into two pens separated by an empty pen and connected by narrow passages that were opened 24 h after weaning. WL interactions accounted for 38% and 68% of all fights and mounts, respectively, during a 7-day experimental period. After the passages were opened, not only BL, but also WL interactions increased significantly (by 6- to 7-fold on the first day of mixing). WL fights then gradually decreased, while WL mounts continued to increase. During the experimental period, the proportion of both WL fights and mounts decreased. The majority of WL fights (%80%) and mounts (%65%) occurred in home pens. A significantly higher percentage of draws was found in WL fights (50% of initiator wins and 41% of draws) compared to BL fights (80% of initiator wins and 11% of draws). Results also showed less asymmetry in the body weight of piglets involved in WL interactions. Mixing of litters at weaning was shown to involve not only intense interactions between unfamiliar piglets but also the recurrence of agonistic interactions between littermates, which is something we should keep in mind when pursuing the highest standards of weaner welfare.
