Spontaneous separation of attractive chiral mixtures.

The separation of chiral matter has garnered significant attention due to its wide-ranging applications in biological and chemical processes. In prior researches, particle interactions were predominantly repulsive, but the indiscriminate attraction among particles under attractive interactions makes the separation of mixtures more difficult. The question of whether chiral mixed particles, characterized by attractive effects, can undergo spontaneous separation, remains unresolved. We study a binary mixture of chiral (counterclockwise or clockwise) active particles with attractive interactions. It is demonstrated that attractive chiral particles can undergo spontaneous separation without the aid of any specific strategies. The key factor driving the separation is the attractive interactions, enabling the formation of stable clusters of particles with same chirality. There exist optimal parameters (self-propelled velocity, angular velocity, and packing fraction) at which the separation is optimal. Our results may contribute to a deeper understanding of the mechanisms behind chiral matter separation and potentially catalyze further experimental investigations in this field.

A rapid and accurate fluorescent sensor array based on lanthanide metal-organic framework for identification and determination of perfluorinated compounds

Perfluorinated compounds (PFCs), as an important class of environmental pollutants, have chemical and structural similarities that make their detection a great technical challenge. This study synthesized three species of metal-organic frameworks (MOFs) using different lanthanide metal ions or organic ligands, which were integrated into a fluorescent sensor array. This innovative approach offers a straightforward, rapid, and precise detection strategy for PFCs. Different ionization properties and fluorinated hydrophobic tails of PFCs lead to different electrostatic attraction and hydrophobic effects between PFCs and sensing elements, which become the basis for differential sensing. Furthermore, the fluorescence signal is more convenient to collect, making the sensor array simple to complete the identification. Combined with pattern recognition methods, the array successfully identified seven kinds of PFCs and mixtures with a classification accuracy of 100 % and a detection limit as low as 51 nM. Finally, the utility of the sensor array in river water sample analysis was verified. The strategy provides an effective method for identifying and determining PFCs and offers new opportunities for developing sensor arrays based on lanthanide MOFs.

The feeding preference of red flour beetle Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) on wheat flour stored at varied temperatures: The perspective of volatile components

As a common pest in wheat flour, Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) is responsible for economic losses and potential risks to food safety. This study aimed to investigate the feeding preferences of T. castaneum on wheat flour stored at different temperatures, analyzed the key flavor compounds influencing its feeding preferences, and laid down the foundation for the development of new T. castaneum attractants and repellents. According to results, in the early storage period, T. castaneum showed a higher preference for feeding on wheat flour stored at higher temperatures, but this trend decreased over the storage time with a preference shift towards the flour preserved at lower temperatures. The findings from GC-MS revealed changes in the types and concentrations of volatile components in wheat flour during storage. PCA and correlation analysis suggested that compounds such as 2-methyldodecane, 3-methyl-3-ethylheptane, benzaldehyde, decanal, and n-hexanol exhibited potential attractiveness to T. castaneum. Conversely, 2-methyloctane, 2,5-dimethyldodecane, and dodecane were identified as potential repellents. At different storage temperatures, benzaldehyde and 2-methyloctane displayed consistent attractant and repellent effects, indicating their potential as effective components for attractance and repellence. Overall, our work shed the light regarding the feeding preference of T. castaneum on wheat flour stored at different temperatures from the perspective of volatile component variations, and provided a theoretical basis for the development of novel attractants and repellents.

Interactive effects of intrasexual competitiveness, same-sex competition, and physical attractiveness on temporal discounting

Studies have shown that men discount the future and prefer immediate-but-smaller over delayed-but-larger rewards when exposed to mating opportunities (e.g., attractive opposite-sex targets) or threats (e.g., same-sex competition) whereas women's discounting in response to similar cues appears mixed, suggesting that mating-motivated discounting is primarily a male phenomenon. Importantly, this line of research has not yet examined the role of individual difference variables as well as how the attractiveness of potential mates and perceptions of competition jointly influence discounting rates. We conducted a novel test of the effect of trait intrasexual competitiveness (ISC) using dating profiles varying on target attractiveness and same-sex competition to observe their interactive effects on participants' discounting. Results showed that when targets were attractive, higher ISC was associated with steeper discounting for both men and women, and this association was stronger when competition was high rather than low. ISC still predicted discounting when targets were low in attractiveness but competition was high; high ISC did not predict discounting only in the low attractiveness and low competition condition. These findings reveal ISC as a factor that leads women to discount as much as men, and that high-ISC individuals may be more responsive to competition than to target attractiveness.

Using the Stimulus-Organism-Response (SOR) theoretical framework, this study explores consumer reactions and behaviors caused by stimulus factors which are then analyzed using Structural Equation Modeling (SEM) PLS techniques with the SmartPLS application based on 156 valid respondents on TikTok. The results are expected to guide fashion business actors in social commerce to design effective marketing strategies using TikTok live streaming by emphasizing aspects of perceived enjoyment to encourage impulse buying.

Uncovering effects of virtual endorser’s attractiveness on consumer behaviors from the perspective of national culture

In the context of social media, more and more enterprises take virtual endorsers for brand marketing. Investigating people’s preferences and concerns about virtual endorsers’ characteristics and seeking to understand users’ feedback on the effectiveness of endorsement with the help of reviews are important for companies to expand their digital marketing strategies. We use the machine learning approach, conduct text mining and regression analysis on the advertisements and reviews, and find the positive effect of attractiveness on purchase intention and the suppressing effect of advertising perception between virtual endorsers’ attractiveness and purchase intention. Users’ high perception of advertising information deepens their impression and improves the effectiveness of advertisements. However, that may lead to psychological revulsion and purchase inhibition, the regression coefficient of advertising perception toward purchase intention is negative and the effect is significant. Fortunately, we confirmed the moderating role of positive emotion to weaken the inhibitory effect. Additionally, the study validates the moderating effect of national culture on the relationship between virtual endorser’s attractiveness and purchase intention. Our findings have positive implications for studying consumer psychology and behaviors by big data analysis, it gives practical suggestions for enterprises to adopt the virtual endorsers’ marketing strategy more effectively and provides references for enterprises to facilitate the digital marketing transformation on social media.

Pull Factors for Event Delegates Moderating Effect Of Cultural Tourism Attraction

This study seeks to explore the pull factors that influence delegates' decision to attend an event. This research also involves the factor of cultural tourism attraction as a moderating variable. It is well known that Yogyakarta as the research location is a city rich in culture, there are many cultural attractions that are favored such as heritage sites, indigenous people's lives, handicraft products, traditional culinary, and a number of other local cultural products. By using Structural Equation Model analysis and involving 190 respondents, namely delegates who attended various events in Yogyakarta, from the results of the study it was found that the pull factors namely accessibility, event organizer (OC), accommodation, venue, price and cultural tourism attraction jointly influenced the decision of delegates to attend the event. Cultural tourism attraction is able to moderate the overall pull factor. The strength of culture that is able to moderate the overall attraction factor indicates that culture is very strong as a novelty event and is a key variable for destinations so that it is attractive to host events.

Ultrafast and efficient extraction of heparin via cationic brush magnetic adsorbents

Heparin is a highly sulfated polysaccharide used extensively as an anticoagulant. However, conventional heparin extraction processes remains time-consuming and inefficient. We report cationic brush magnetic adsorbents by grafting poly(3-acrylamidopropyl) trimethylammonium chloride-co-N‑isopropylacrylamide random copolymers onto the surface of Fe3O4 for ultrafast and efficient heparin extraction. The fabricated adsorbent demonstrated an excellent adsorption capacity of 169.36 mg g−1 and a record-breaking adsorption rate towards heparin due to the introduction of N‑isopropylacrylamide, providing more adsorption sites and larger transport channels for the macromolecule heparin to access active sites. In addition, the adsorption capacity and rate for crude heparin were significantly better than those of commercial resin. Thermodynamic parameters implied that the heparin adsorption was spontaneous and endothermic process. The adsorption mechanism can be described by the synergistic effect of electrostatic attraction and hydrogen bond. This study paved an innovative approach to simultaneously enhance the adsorption rate and capacity of the adsorbent for polysaccharide.

Attraction Agglomeration and Destination Agglomeration: The Case of Chinese National Scenic Areas

We examine the effect of attraction and destination agglomerations on tourism revenues and tourist flows. Using data from 184 national scenic areas in China for the 2012 to 2017 period as the case study for our two-level agglomeration model, we find that the attraction agglomeration yields cooperative competition at the micro level of tourist districts. This co-existence of compatible and competitive effects determines not only individual national scenic areas’ tourism revenues and tourist flows but also the attractiveness of tourist districts where these national scenic areas are located. At the macro level of tourism destinations, we find that the destination agglomeration only yields a competitive effect, adversely affecting the tourism revenues and tourist flows of individual national scenic areas inside these tourism destinations. Our results suggest that policymakers must consider cooperative competition when managing existing tourist attractions and planning for future ones.

Fracture Propagation of Multi-Stage Radial Wellbore Fracturing in Tight Sandstone Reservoir

Radial wellbore fracturing is a promising technology for stimulating tight sandstone reservoirs. However, simultaneous fracturing of multiple radial wellbores often leads to unsuccessful treatments. This paper proposes a novel technology called multi-stage radial wellbore fracturing (MRWF) to address this challenge. A numerical model based on the finite element/meshfree method is established to investigate the effects of various parameters on the fracture propagation of MRWF, including the azimuth of the radial wellbore, the horizontal stress difference, and the rock matrix permeability. The results show that previously created fractures have an attraction for subsequently created fractures, significantly influencing fracture propagation. A conceptual model is proposed to explain the variations in the fracture propagation of MRWF, highlighting three critical effect factors: the attraction effect, the orientation effect of the radial wellbore, and the deflection effect of the maximum horizontal principal stress. Fracture geometry is quantitatively assessed through the deviation distance, which indicates the radial wellbore’s ability to guide fracture propagation along its axis. As the azimuth increases, the deviation distances can either increase or decrease, depending on the specific radial wellbore layouts. Decreasing the horizontal stress difference and increasing the rock matrix permeability both increase the deviation distance.

The results of the study indicate that 1) tourist attractions do not have a positive and significant effect on revisit intentions, 2) price perceptions have a positive and significant effect on revisit intentions, 3) service quality has a positive and significant effect on revisit intentions, 4) tourist attractions, price perceptions, and service quality simultaneously affect revisit intentions.

Influence of male’s facial attractiveness, vocal attractiveness and social interest on female’s decisions of fairness

The present study employed dictator game and ultimatum game to investigate the effect of facial attractiveness, vocal attractiveness and social interest in expressing positive (“I like you”) versus negative signals (“I don’t like you”) on decision making. Female participants played against male recipients in dictator game and ultimatum game while played against male proposers in ultimatum game. Results showed that participants offered recipients with attractive faces more money than recipients with unattractive faces. Participants also offered recipients with attractive voices more money than recipients with unattractive voices, especially under the positive social interest condition. Moreover, participants allocated more money to recipients who expressed positive social interest than those who expressed negative social interest, whereas they would also expect proposers who expressed positive social interest to offer them more money than proposers who expressed negative social interest. Overall, the results inform beauty premium for faces and voices on opposite-sex economic bargaining. Social interest also affects decision outcomes. However, the beauty premium and effect of social interest varies with participants’ roles.

An integrative review of the decoy effect on choice behavior

AbstractSince 1982, the decoy effect has been one of consumer behavior literature's most discussed and documented phenomena. It has several managerial implications in gaining strategic advantages, such as product management and profit maximization. Numerous attempts have been made to explain the decoy effect. However, there is no clear consensus in the literature regarding the underlying mechanism of the decoy effect. This paper presents a systematic literature review to integrate the four decades of decoy effect research. We analyze the contribution of literature, establish linkages between them, and provide a holistic view of understanding the decoy effect that is beneficial for academicians and practitioners. We discuss and differentiate four types of decoy alternatives that produce three types of decoy effects: attraction effect, compromise effect, and phantom decoy effect. We provide a comprehensive list of moderating factors of the decoy effect. Further, we critically review and integrate various explanatory models to better understand the underlying mechanism of the decoy effect. Finally, we discuss several promising avenues for future research.

An investigation into the influence of context effects on crowd exit selection under gender difference in indoor evacuation.

Exit selection is crucial in indoor emergency evacuation. Domestic and foreign scholars have found that exit choice behavior is influenced by three factors: environmental factors, social interactions, and individual internal factors. Previous studies have shown that in addition to a single environmental factor affecting exit decisions, the influence of other available exit options in the context can ultimately lead to a reversal of exit decisions -The context effect. However, the impact of context effects on exit decisions in emergency situations has not been thoroughly explored. Therefore, this article identifies three basic independent variables: context effects, crowd flows, and gender differences, to study the exit decisions of different gender groups facing different crowd flows, as well as how context effects affect existing exit decisions. In this paper, we used virtual reality technology to construct an indoor fire scene and designed a total of 15 virtual experiments with different crowd distribution or context effects. 131 participants were divided into two groups, male and female, and their exit decisions were observed under different crowd flows and contextual effects. The research results show that: 1) Both men and women have an innate preference to avoid crowded exits, and the proportion of following crowd evacuation significantly decreases when there are crowded crowds in the scene; 2) The exit decisions of female participants are more influenced by the crowd, while men tend to be more influenced by context effects when evacuating independently; 3) The context effects on exit decisions in emergency situations is statistically significant, and this performance is more significant in the male population. Further analysis reveals that similarity effects have a more significant impact on exit decisions than attraction effects. These findings provide deeper insights into the exit choice behavior of the population and may contribute to the design of safe exits in indoor buildings. In addition, this article emphasizes the importance of context effects and provides a foundation for future research.

Persistence or decay of strategic asymmetric dominance in repeated dyadic games?

AbstractIn a dyadic game, strategic asymmetric dominance occurs when a player’s preference for one strategy A relative to another B is systematically increased by the addition of a third strategy Z, strictly dominated by A but not by B. There are theoretical and empirical grounds for believing that this effect should decline over repetitions, and other grounds for believing, on the contrary, that it should persist. To investigate this question experimentally, 30 participant pairs played 50 rounds of one symmetric and two asymmetric 3 × 3 games each having one strategy strictly dominated by one other, and a control group played 2 × 2 versions of the same games with dominated strategies removed. The strategic asymmetric dominance effect was observed in the repeated-choice data: dominant strategies in the 3 × 3 versions were chosen more frequently than the corresponding strategies in the 2 × 2 versions. Time series analysis revealed a significant decline in the effect over repetitions in the symmetric game only. Supplementary verbal protocol analysis helped to clarify the players’ reasoning and to explain the results.
