Examining the contributing factors of virtual event quality toward event satisfaction among attendees

Due to the rising acceptance of virtual events, more empirical studies are needed to determine factors influencing attendees’ satisfaction. It is crucial to comprehend the essential factors determining the quality of virtual events as the virtual world continues to define the future of event experiences. Given these considerations, event planners may create and deploy virtual experiences meeting the diverse needs and preferences of the attendees. Hence, the main purpose of this paper is to examine the influence of virtual event quality dimensions on the level of event satisfaction among the attendees. A cross-sectional study was undertaken by administering a survey instrument to collect response data from participants in virtual events. There were 124 valid responses obtained for data analysis. Descriptive and inferential analyses were performed using IBM SPSS version 28. The study findings revealed that there was a statistically significant relationship between the quality of virtual event factors and event satisfaction among the attendees. The results of regression analysis indicated that vividness (p=0.016), functionality (p=0.003), entertainment (p=0.029), fulfillment (p=0.037), privacy (p=0.037), and social presence (p=0.001) were found to be significant predictors of event satisfaction. In conclusion, this study highlights the importance of considering several factors of event quality, particularly in planning and implementing virtual events. Event organizers can enhance attendees’ satisfaction through the use of more immersive and substantial virtual experiences, by focusing on attributes such as vividness, functionality, entertainment, fulfillment, privacy and social presence.

Ten questions concerning Architectural Acoustics

Building and room acoustics are relatively modern architectural and engineering disciplines. Nevertheless, acoustics was also a concern for buildings in the past, e.g., in theatres in ancient Greece and in Roman times. Nowadays, we spend 80–90 % of our time indoors, and sound impacts our communication and actions in an environment to a great extent. Therefore, acoustic aspects should be considered appropriately in the Environmental Quality and Global Comfort context as part of the overall aspects of building physics, although other factors (e.g., thermal, air quality, etc.) are conventionally considered more “mainstream”. The ten questions considered in this paper range from the basic definitions underlying the differences between building and room acoustics, to more applied topics about how to measure, simulate and use acoustic data in the design of the built environment. Significant research activities have been conducted by acoustic experts on different aspects related to the measurements of physical properties, perceptual aspects and technological development in both the physical and virtual dimensions, thereby paving the way towards a more inclusive and healthier acoustic environment. Apart from illustrating the current state of the art, the answers to these questions point out the still existing gaps in the field and future challenges, thereby highlighting the new competencies required to support the design of the acoustic environment, focusing on the physical, physiological, and psychological needs of the users.

A stochastic Schrödinger equation and matrix product state approach to carrier transport in organic semiconductors with nonlocal electron-phonon interaction.

Evaluation of the charge transport property of organic semiconductors requires exact quantum dynamics simulation of large systems. We present a numerically nearly exact approach to investigate carrier transport dynamics in organic semiconductors by extending the non-Markovian stochastic Schrödinger equation with complex frequency modes to a forward-backward scheme and by solving it using the matrix product state (MPS) approach. By utilizing the forward-backward formalism for noise generation, the bath correlation function can be effectively treated as a temperature-independent imaginary part, enabling a more accurate decomposition with fewer complex frequency modes. Using this approach, we study the carrier transport and mobility in the one-dimensional Peierls model, where the nonlocal electron-phonon interaction is taken into account. The reliability of this approach was validated by comparing carrier diffusion motion with those obtained from the hierarchical equations of motion method across various parameter regimes of the phonon bath. The efficiency was demonstrated by the modest virtual bond dimensions of MPS and the low scaling of the computational time with the system size.

This integration isnt merely a technological endeavor; its a holistic approach that considers people, processes, and technology.

A study of pedestrian wayfinding behavior based on desktop VR considering both spatial knowledge and visual information

Understanding pedestrian wayfinding behavior is crucial for traffic management and building design. The use of virtual reality technology presents an efficient approach for investigating pedestrian wayfinding behavior in large public spaces, offering numerous advantages for data collection. However, the impact of different scenario dimensions on pedestrian wayfinding behavior in large public spaces remains unclear. Additionally, the selection of virtual experiment scenario dimensions currently relies primarily on researchers’ experience and practical conditions, lacking sufficient evidence to support their rational. Another challenge is the limited focus on spatial knowledge’s effect on wayfinding behavior, with insufficient analysis of the utility of pedestrian visual information and a lack of precise methods to quantify visual field information accurately. This study addresses these gaps by incorporating spatial knowledge at multiple scales and pedestrian visual field information as influencing factors in the analysis of wayfinding behavior. Furthermore, it distinguishes between three-dimensional and two-dimensional scenarios to compare the impact of dimensional differences on pedestrian wayfinding behavior. By analyzing behavior data from non-immersive wayfinding experiments, this research employs statistical analysis methods and a deep learning framework to derive results regarding the factors influencing wayfinding behavior. The findings demonstrate that considering both spatial and visual field information effectively enhances the predictive ability of the wayfinding model. Additionally, dimensional differences significantly influence the pedestrian wayfinding process. These results offer empirical evidence to guide researchers in selecting experimental scenarios of pedestrian behavior and provide insights for public space layout, signage design, and improving pedestrian efficiency.

This study delves into the intricate dynamics of South Korea’s grain production and trade, specifically scrutinizing water resource management and sustainability trends from 1991 to 2022. The primary objective was to assess the temporal evolution of South Korea’s agricultural virtual water trade in maize, soybeans and wheat. Employing the virtual water flows assessment method, water stress index, and an unsustainable import fraction (UIF) analysis, this research aimed to uncover key patterns and dynamics within the agricultural grain trade landscape. Utilizing comprehensive datasets encompassing grain trade, as well as water and land footprint data, this study assessed the intricate interplay between agricultural production, trade, and resource utilization. Results showed a reduction in local production for soybeans and a slight increase in domestic wheat production over the study period. In addition, the study revealed an overall increase in the virtual water imports associated with grain crops, with maize exhibiting the steepest upward trend in comparison with the other grains (wheat and soybeans). Furthermore, the study demonstrated that the import of maize contributed the highest amount of water and land savings, implying that this grain crop had the most significant impact on conserving local water and land resources. Environmental impact assessments, including water stress indices and the unsustainable import fractions, contributed to a comprehensive understanding of grain trade sustainability with concrete result values and insights, highlighting the intricate interplay of international grain trade and local water resource conservation in South Korea. By scrutinizing the virtual land and water dimensions of grain trade, this research offers valuable insights for policymakers and researchers striving to navigate the nexus of agriculture, trade, and resource management. The findings hold significance in the context of ensuring food security, optimizing resource allocation, and fostering sustainable agricultural practices in a dynamically evolving global landscape.

PRODEC for human systems integration of increasingly autonomous systems

AbstractThe purpose of the PRODEC scenario‐based design method is the incremental cross‐fertilization and refinement of procedural scenarios and declarative configurations. It uses virtual prototypes of the developed systems (mainly life‐critical systems) to conduct human‐in‐the‐loop simulations (HITLSs). Based on human systems integration (HSI) principles and criteria, as well as expertise and experience in the domain at stake, this HSI approach grounded in virtual environments requires a clear definition of physical and cognitive tangibility metrics to assess the distance between virtual and tangible (grasp) dimensions of the system being developed when it is put to work. PRODEC considers human and machine systems described in terms of structures and functions incrementally designed using procedural scenarios (i.e., stories) in task and activity networks, which provide life to declarative configurations (i.e., system's functions and structures). This active modeling and simulation process enables the discovery of emergent structures and functions of the system being developed when it is virtually operated. PRODEC's use is illustrated in an example. We discuss the use of PRODEC and its results as to how they can be used with digital twins.

Digital Embodiment as a Tool for Constructing the Self in Politics

This article offers an exploration of the theoretical and methodological implications related to the concept of digital embodiment in the field of contemporary communication. It seeks to analyze a crucial intersection between the virtual and material dimensions of human experience, enabling a deeper understanding of how bodies are shaped, visualized, and experienced in the digital age. Specifically, through this conceptual lens, we examine how human bodies are engaged in continuous interaction with digital technologies, giving rise to new forms of presence and identity. Therefore, we will seek to analyze how the personalization of the body within political communication has been profoundly affected by the virtualization of human experience. Next, we will introduce a new approach, useful for studying this fusion, that can emphasize the importance of analyzing this issue using ethnography, which is useful for fully understanding the complex dynamics surrounding the personalized digital body.

A novel DT-based intelligent experiment method for complex industrial products

To alleviate the contradiction between multi-disciplinary coupling, high intelligence, and the difficulty in conducting direct experiments for product testing in the industrial field, a new method of intelligent experiment is proposed based on the digital twin. This method exhibits typical characteristics such as the joint integration of knowledge and data and the fusion of virtual and physical elements. The intelligent experiment technology framework suitable for complex industrial product experiment is established through a four-step intelligent experiment transformation method in the industrial field. These steps include a laboratory prototype experiment, a virtual simulation experiment, a hardware-in-the-loop experiment, and a virtual-physical fusion experiment. Aiming to address three typical engineering problems related to position and posture, posture and performance coupling, and micro force testing, three knowledge and data joint driving methods based on Virtual Reality (VR) multidisciplinary fusion calculations are proposed. A multi-agent operation scene is created, which maintains shape, space–time, physical behavior, performance, and macro–micro consistencies. Design and monitoring experiments are completed to achieve the co-evolution and closed-loop feedback between the physical and virtual dimensions. Taking the hydraulic support used in coal mines as an example, a high confidence agent model is established based on the single-machine hydraulic support posture monitoring and loading test bench. Through a virtual and physical cooperative operation mode involving multi-agents and physical models, six types of experiments are designed, including pose, force, and monitoring. Relevant experimental research shows that the requirements of industrial experiments can be met under laboratory conditions. This experiment framework can provide reliable experimental support for the optimization and intelligent monitoring of complex industrial products.

Forms of interaction of units of the National Police units with the public under martial law

The team of authors has emphasised that the issue of forms of interaction between the police and the public under martial law is becoming one of the basic ones, the study of which is of a strategic nature, as it is related to the establishment of stable mutual relations between the police and the public at the organisational, managerial and ideological levels, which in the future can contribute to mutual coverage and complementation of problematic aspects of the activities of both police units and the public. In the course of the research, the authors’ understanding of the public under martial law has been formed, taking into account the international and virtual dimensions of its functioning, as well as the main features of its activity have been highlighted. An attempt has also been made to outline the features of police activity under martial law, which in one way or another are related to interaction with the public. Also, the most common forms of interaction between the police and the public were separately considered: joint delivery of humanitarian aid to the civilian population and units of the Armed Forces of Ukraine, the escort by the police of humanitarian cargo organized by the public; joint evacuation of the population from the regions of active hostilities, ensuring public safety at all stages of evacuation; joint trainings for the public on safety issues, provision of police premises, including shelter, for public safety needs; the use of police premises as “points of invincibility”, allowing the public to use generators, heaters, etc.; conducting trainings by the representatives of the public for the personnel of police units, in particular, participation in the organization of trainings on pre-medical care of representatives of public organizations, paramedics and professional trainers on pre-medical care.
 Taking into account the fundamental importance of developing, systematizing, and scientifically understanding the peculiarities of the interaction of police units with the public under martial law, there is a need to conduct new research in this area, develop separate methodological recommendations, manuals, and implement comprehensive programs for the dissemination of effective practices of such interaction among the public.

Poezija u doba digitalne (re)produkcije - digitalna aura u novomedijskoj poeziji

The paper "Poetry in the Age of Digital (Re)production: Digital Aura in New Media Poetry" explores the evolution of new media poetry from the 1990s to the present day, engaging with Walter Benjamin's concept of the aura of authentic art to analyze three forms of new media poetry and define the digital aura in this context. The following analysis is grounded in new media theories, particularly those of Lev Manovich and N. Katherine Hayles. The paper discusses how digital technologies have transformed the creation, distribution, and consumption of poetry and challenged notions of authenticity and originality. It emphasizes the interaction between poets and software, the blurring of boundaries between different forms of new media art, and the concept of materiality in the digital realm. The paper highlights the significance of the material aspects of digital art, drawing attention to the interplay between the physical and virtual dimensions and the sensory experiences they provide. The paper traces the development of new media poetry in different web eras - Web 1.0 helped launch e-poetry, Web 2.0 enabled poetry on social media platforms, and Web 3.0 engraved NFT poetry on blockchain technology. The analysis of three distinct forms of new media poetry - kinetic poetry, Instapoetry, and NFT poetry - demonstrates how each form engages with the digital aura and challenges traditional notions of authenticity and artistic presence. The paper concludes that the digital aura is not an inherent characteristic of artwork, but a continuous process realized through the interactions of artists and the audience with code, software, and interface.

The Identification and Analysis of the Centers of Geographical Public Opinions in Flood Disasters Based on Improved Naïve Bayes Network.

The increasing frequency of floods and the lack of protective measures have the potential to cause severe damage. Working from the perspective of network public opinion is an effective way to understand flood disasters. However, the existing research tends to focus on a single perspective, such as the characteristics of the text, algorithm optimization, or spatial location recognition, while scholars have paid much less attention to the impact of social-psychological differences in space on network public opinion. This research is based on the following hypothesis: When public opinions break out, the differences of network public opinions in geography will form spatially different centers of geographical public opinions in flood disasters (CGeoPOFDs). These centers represent the cities that receive the most attention from network public opinion. Based on this hypothesis, this study proposes a new way of identifying and analyzing CGeoPOFDs. First, two optimization strategies were applied to enhance a naïve Bayes network: syntactic parsing, which was used to optimize the selection of feature word vectors, and ensemble learning, which enabled multi-classifier fusion optimization. Social media data were classified through the improved algorithm, and then, various methods (hotspot analysis, geographic mapping, and sentiment analysis) were used to identify CGeoPOFDs. Finally, analysis was performed in terms of spatiotemporal, virtual, and real dimensions. In addition, microblog social data and real disaster data were used to arrive at empirical results. According to the study findings, the identified CGeoPOFDs offered traditional characteristics of network public opinion while also featuring unique spatiotemporal characteristics. Over time, CGeoPOFDs demonstrated spatial aggregation and bias diffusion and an overall positive emotional tendency.

Electron Propagator Self-Energies versus Improved GW100 Vertical Ionization Energies.

Ab initio electron propagator (EP) methods that are free of adjustable parameters in their self-energy formulae and in the generation of their orbital bases have been applied to the calculation of the lowest vertical ionization energies (VIEs) of the GW100 set. An improved set of standard results accompanied by irreducible representation assignments has been produced indirectly with coupled-cluster singles and doubles plus perturbative triples, i.e., CCSD(T), total energy differences at initial-state geometries reoptimized (in 28 cases) with the largest applicable point groups. The best compromises of accuracy and efficiency belong to a new generation of EP self-energies, several members of which may be derived from an intermediately normalized, Hermitized super-operator metric. The following diagonal self-energy methods are optimal: opposite-spin non-Dyson second order (os-nD-D2), approximately renormalized partial third order (P3+), approximately renormalized quasiparticle third order (Q3+), and non-Dyson approximately renormalized linear third order version B (nD-L3+B). Their mean absolute errors (MAEs) in electron volts and arithmetic scaling factors expressed in terms of occupied (O) and virtual (V) orbital dimensions are, respectively, (0.18, OV2), (0.14, O2V3), (0.15, O2V3), and (0.11, OV4). The 0.06 eV MAE for the non-diagonal, sixth-power (O2V4) Brueckner doubles, triple-field operator (BD-T1) EP method is exceeded by the 0.1 eV MAE with respect to experiments in seventh-power, ΔCCSD(T) calculations and indicates that BD-T1 may serve as a direct, spin-symmetry-conserving alternative in the generation of standard results for VIEs of larger, closed-shell molecules.

Towards digital organized crime and digital sociology of organized crime.

As technology has changed people’s lives, criminal phenomena are also constantly evolving. Today’s digital society is changing the activities of organized crime and organized crime groups. In the digital society, very different organized crime groups coexist with different organizational models: from online cybercrime to traditional organized crime groups to hybrid criminal groups in which humans and machines ‘collaborate’ in new and close ways in networks of human and non-human actors. These criminal groups commit very different organized crime activities, from the most technological to the most traditional, and move from online to offline. They use technology and interact with computers for a variety of purposes, and the distinction between the physical and virtual dimensions of organized crime is increasingly blurred. These radical developments do not seem to be accompanied by a new criminological theoretical interpretive framework, with a definition of organized crime that is able to account for the changes that digital society brings to organized crime and generate modern research hypotheses. This article proposes the concept of digital organized crime and the spectrum theory of digital organized crimes, to be embedded within a current, revised sociological theory of the organization of crime and deviance in digital society (a new theory of digital criminal organizing) and argues that the study of digital organized crime will increasingly require a digital sociology of organized crime. Criminologists are called upon to work in this direction.

From Disembedding to Digital Re-Embedding: Social Media Empowerment and Solidarity Practices of Chinese Truck Drivers

In China, truck drivers in the logistics industry have used social media to form various networked organizations for mutual assistance and protection of rights and interests. This study examines the organizational practices of Chinese truck drivers on social media (i.e., WeChat and Douyin). Using online communities, Chinese truck drivers have constructed a new type of solidarity that includes virtual and practical dimensions. Social media empowerment has expanded the social capital of truck drivers, promoting social integration and resource redistribution. This online self-organization provides a reference for collaborative governance among self-employed workers who want to promote professional solidarity. However, our findings also indicate that combating the exploitation of digital labor on capital platforms is fundamentally difficult for organized labor groups.
