Internet User Stickiness in the Social Q & A Community from the Perspective of Interactivity – A Case Study on Zhihu Website

This paper mainly explores how the user’s perceptual interaction towards a specific website affects the user stickiness and the interaction mechanism of various influencing factors of user stickiness, which may encourage socialized Q & A community operators to adopt more appropriate ways to enhance user’s stickiness. We comprehensively use the planning behavior theory and technology acceptance model with the perceptual perspective of interaction. Based on the framework of “belief → attitude → intention”, an attempt is made to construct a conceptual model of influencing factors of user stickiness in socialized Q & A community by collecting the data through questionnaire survey, and using spss23.0 and amos23.0 to analyze the data and validate the model. The empirical research results prove that the factors such as perceived usefulness, perceived ease of use, information exchange perception, social interaction perception satisfaction, and heart flow experience have positive effects on social users. We conclude that the operators can build and consolidate user engagement, attract and retain the users by enhancing interactive perception, optimizing user experience, and improving their satisfaction.

The question of access: Toward an equitable future of computational design

Digital fabrication and its cultivated spaces promise to break disciplinary boundaries and enable access to its technologies and computation for the broader public. This paper examines the trope of “access” in digital fabrication, design, and craft, and illustrates how it unfolds in these spaces and practices. An equitable future is one that builds on and creates space for multiple bodies, knowledges, and skills; allows perceptual interaction and corporeal engagement with people, materials, and tools; and employs technologies accessible to broad groups of society. By conducting comparative and transnational ethnographic studies at digital fabrication and crafting sites, and performing craft-centered computational design studies, we offer a critical description of what access looks like in an equitable future that includes digital fabrication. The study highlights the need to examine universal conceptions and study how they are operationalized in broader narratives and design pedagogy traditions.

THE ROLE OF GAME TEACHING TECHNOLOGIES IN THE PROFESSIONAL FORMATION OF STUDENTS - FUTURE LAWYERS

The article is devoted to identifying the role of gaming teaching technologies in the professional development of students - future lawyers. In the article, the author proves the thesis that gaming teaching technologies contribute to the implementation of such functions as: an activating function aimed at stimulating the cognitive interest of students both in theoretical knowledge and practical skills for the implementation of successful professional activities; developing, aimed at the formation of sustainable professional mobility on the basis of mastered professional and general professional competencies; psychological, which consists in the formation of the main mental cognitive processes, including: attention, imagination, thinking, speech, memory; communicative, aimed at developing the ability to business communication; educational, contributing to the regulation of interpersonal relations on the basis of social-perceptual interaction. Analysis and interpretation of the results of numerous studies made it possible to conclude in the article that in the course of the educational process, an integrated solution of the tasks of teaching, upbringing and the formation of the student's personality is carried out in the framework of training a highly qualified lawyer with the ability to fiercely compete in the modern labor market, expressing the most important guarantees of ensuring successful employment. The game technology of teaching in the article is presented as a reproduction of a genuine professional situation in which all students participate and have the opportunity to realize their individual status roles, in which simplified models of future professional activities are expressed. The main purpose of the article is to establish the role and place of gaming teaching technologies in the formation and development of a student's personality as a future qualified lawyer, ready for successful creative professional activity.

Touch inhibits touch: sanshool-induced paradoxical tingling reveals perceptual interaction between somatosensory submodalities

Human perception of touch is mediated by inputs from multiple channels. Classical theories postulate independent contributions of each channel to each tactile feature, with little or no interaction between channels. In contrast to this view, we show that inputs from two sub-modalities of mechanical input channels interact to determine tactile perception. The flutter-range vibration channel was activated anomalously using hydroxy-α-sanshool , a bioactive compound of Szechuan pepper, which chemically induces vibration-like tingling sensations. We tested whether this tingling sensation on the lips was modulated by sustained mechanical pressure. Across four experiments, we show that sustained touch inhibits sanshool tingling sensations in a location-specific, pressure-level and time-dependent manner. Additional experiments ruled out the mediation of this interaction by nociceptive or affective (C-tactile) channels. These results reveal novel inhibitory influence from steady pressure onto flutter-range tactile perceptual channels, consistent with early-stage interactions between mechanoreceptor inputs within the somatosensory pathway.

Moving in unison after perceptual interruption

Humans interact in groups through various perception and action channels. The continuity of interaction despite a transient loss of perceptual contact often exists and contributes to goal achievement. Here, we study the dynamics of this continuity, in two experiments involving groups of participants ($$N=7$$ N = 7 ) synchronizing their movements in space and in time. We show that behavioural unison can be maintained after perceptual contact has been lost, for about 7s. Agent similarity and spatial configuration in the group modulated synchronization performance, differently so when perceptual interaction was present or when it was memorized. Modelling these data through a network of oscillators enabled us to clarify the double origin of this memory effect, of individual and social nature. These results shed new light into why humans continue to move in unison after perceptual interruption, and are consequential for a wide variety of applications at work, in art and in sport.

Characterization of Odor-Active Volatiles and Odor Contribution Based on Binary Interaction Effects in Mango and Vodka Cocktail

Thirty-six volatile compounds, composed of 18 esters, 10 terpenes, and 8 others, were detected by headspace-solid phase microextraction (HS-SPME) equipped with gas chromatography-mass spectrometry (GC-MS) in mango and vodka cocktail. Moreover, these compounds were detected by olfactometry using aroma intensities. Comparing these compounds revealed that the aroma intensities (AIs) of limonene, 3-carene, myrcene, β-caryophyllene, and citronellyl propanoate were higher than others (AIs ≥ 4). In this context, limonene was selected as the reference compound on the basis of the strongest component model. The aim of this study was to determine the perceptual interaction between limonene and 3-carene, myrcene, β-caryophyllene, citronellyl propanoate, respectively, in a binary mixture. In addition, feller’s addition model revealed that limonene presented an addition effect when combined with 3-carene, myrcene, β-caryophyllene, and citronellyl propanoate. It could be stated that these compounds played an important role in the aroma of mango and vodka cocktail. The results demonstrated that molecular structure and the ratio between compounds affected the synergistic effect, and compounds with similar structure and aroma were more prone to undergo addition and synergy.
