The recent and swift move to virtual working has highlighted a need for greater understanding of how to best communicate remotely for work, how well team members are able to identify the correct communication mediums for their tasks and how team members align on how to complete these tasks. Drawing on Media Synchronicity Theory (MST), we examine communication-based subgroup dynamics in terms of faultline strength—the degree to which a team is hypothetically divided by lines of communication media they use—and subgroup imbalance regarding the influence of communication-based subgroup dynamics on virtual team sociability, and subsequently, team coordination. Results from a field study (Study 1) with 292 team members belonging to 37 virtual teams, and an experiment (Study 2) with 385 participants provided support for the hypotheses. Our findings contribute to existing theory by underscoring the idea that it is not simply virtuality, but the misalignment of the use of communication mediums among team members that plays a key role in the development of communication challenges in virtual teams. The study takes a novel approach by addressing how faultline strength within virtual teams that can cause communication challenges. Consequently, organizations are encouraged to pay attention to guidelines of the use of virtual communication tools and team composition to enhance communication and collaboration within virtual teams.

Rapport and rapport-building are fundamental building blocks of the sales process. As part of the approach in personal selling, as well as a relationship-building mechanism, rapport allows salespeople to facilitate customer engagement. This paper reviews and synthesizes articles over four decades of research on rapport and rapport-building within buyer-seller relationships to provide insight into the gaps in the current literature and provide an overarching conceptual model of where rapport research stands. This analysis of the research from theoretical and methodological perspectives identifies three major themes in the existing literature and offers five gaps where the literature should grow going forward. Building on these gaps, we identify an agenda for future research that extends knowledge in this domain, particularly as salespeople grapple with changing digital communications and relationship-building in virtual spaces with customers.

Asymmetric key cryptography is crucial for securing digital communications by encrypting data and ensuring information integrity. The Rivest-Shamir-Adleman (RSA) cryptosystem is widely used, with its security primarily relying on the complexity of the integer factorization problem, particularly the modulus N = pq. Adversaries attempting to factor the prime factors p and q have made specific assumptions, such as targeting scenarios where p and q exhibit vulnerabilities like those in Pollard's weak prime structures or when partial knowledge about the least significant bits (LSBs) of these primes is available. These weaknesses allow adversaries to efficiently factor the modulus N in polynomial time, compromising RSA encryption security. This paper broadens the understanding of such vulnerabilities by introducing three additional forms of near-square primes. These new forms express N as p×q in the following ways: (am-ra)(bm-rb) and (am±ra)(bm±rb), where a and b are positive integers, and m is a positive even number. It is assumed that ra and rb, corresponding to the LSBs of p and q, are known to the attacker. This study demonstrates the efficient factorization of N under these assumptions and quantifies the impact of this attack on the number of primes. These findings highlight a significant risk to RSA users and emphasize the need for countermeasures to mitigate this attack's potential impact. [ABSTRACT FROM AUTHOR]

This study aims to shed light on health disparities in Internet use among older adults at the onset of the COVID-19 pandemic. Using data from the 2020 German Ageing Survey short survey (N = 2243), we examined the links between self-rated health (SRH, independent variable) and four Internet use purposes (dependent variables) that might have been particularly relevant for older adults with health limitations during the pandemic: online information search, maintaining social contacts, religious purposes, and consultations with doctors or therapists. Multivariate regression analyses revealed that older adults with poor SRH were more likely than those with good SRH to use the Internet for online consultations with doctors or therapists, whereas they were less likely to use the Internet to search for information and to maintain social contacts at least once per week. This hints to health-related inequalities in Internet use which merit further investigation. [ABSTRACT FROM AUTHOR]

This article explores identity construction in citizen science web texts. Keyness and concordance analyses show that these texts reflect, construct and negotiate identity construction in various ways to ultimately support citizen participation in scientific processes. Scientists primarily construct a professional identity through self-representation markers ('we' pronouns). They present themselves as credible professionals, aligned with the socially established values and ideologies of the scientific community. In addition, they appear to create a collective identity to promote empathy and to encourage and maintain citizen engagement in scientific processes. However, processes of indexicality and relationality – that is positioning and dialogism – reveal that the construction of a professional identity is consistently made more relevant than a collective expert-crowd identity, thus exposing overt power asymmetries. Even when dialogue between experts and nonexperts is encouraged, all the monologic and dialogic interactions established by the hypertext structure of the project sites reflect power imbalances.

In a modern digital workplace, leaders must have the necessary skills to lead employees virtually. Despite its high practical and theoretical relevance, a consensus on crucial digital competencies for virtual leaders is lacking, hindering a systematic exploration of the leader's role in facilitating technology use. In the present article, we propose a new concept and instrument to assess leader digital competence (LDC). After reviewing the literature, we establish three dimensions of LDC, centering around the leader's ability and inclination to select, promote, and enable technology and digital media among their employees. We provide support for the scale's convergent, discriminant, criterion-related, and incremental validity using four independent samples (N1 = 156, N2 = 309, N3 = 201, N4 employee = 452, N4 leader = 93). Furthermore, results support the reliability and factor structure with the three proposed dimensions of the 10-item LDC scale. The findings demonstrate that the scale represents a psychometrically sound instrument, useful for further examining conditions for effectiveness in the virtual environment. Future research should aim to advance the understanding of antecedents and situational factors that influence the relevance of LDC and its impact on employee, team, and organizational outcomes.

We examined how early childhood education and care (ECEC) centers supported families during the Covid-19 lockdown and whether the extent and type of support were associated with parental burnout. An online survey was filled out by 521 Finnish parents (88% mothers), and the data were analyzed using the Mann–Whitney U-test and analysis of covariance (ANCOVA). A total of 81% of the parents were contacted by ECEC personnel during lockdown, and 19% were not contacted at all, although 9% would have wished for contact. The support consisted mainly of guidance for the child's daily activities and communication via letters and greetings. Out of the parents, 33% found the support helpful, 36% sometimes helpful, and 31% nonhelpful. The more support the parents received, the less burned out they were. Particularly, food aid and advice to contact the ECEC centers, if needed, were negatively connected to parental burnout. [ABSTRACT FROM AUTHOR]

Interoperability is a critical factor for the success of e-government services, as it enables different public information systems to communicate in a consistent and accurate manner. Governments are making significant efforts to improve their public e-services interactions and promote e-government interoperability. Morocco has developed an e-government interoperability framework that lists compliance rules and references for the development of public information systems. Unfortunately, Moroccan public administrations still work independently and operate as siloed organizations. To deal with this problem, it is essential to implement a common vocabulary (CV) for public services that public administrations can share to formalize public data, enhance exchange between information systems, and ensure data interoperability. In this light, this work presents a CV to standardize public services data, define concepts and relationships. The standardized vocabulary is defined using RDF/XML serialization format and incorporates fundamental declarations to ensure digital communication in Moroccan public services. The approach is illustrated through a case study of e-health service. The study shows the potential added value of creating a national vocabulary. It helps public administrations to structure data, interoperate more effectively and accelerate digital transformation. [ABSTRACT FROM AUTHOR]

In this article, I design a predictor-based neural network (NN) controller for unmanned aerial vehicles (UAVs) with input quantization to address the trajectory tracking problem in the presence of time-varying disturbances caused by aerodynamics and external environment. The NN with a state predictor (SP) is employed in the controller design to improve transient performance without high-frequency oscillations and address the problem of instability caused by the time-varying disturbances. Additionally, the prediction errors from the SP are used to update the learning rate of the NN, resulting in smoother and faster learning responses. Furthermore, a hysteresis quantizer is employed to discretize signals and reduce the transmission burden on digital hardware, which can enhance the suitability of the system for practical implementation. Based on the Lyapunov method, the closed-loop system of the UAV achieves input-to-state stability (ISS). Finally, to validate and assess the performance and effectiveness of our proposed control method, I present and analyze both simulation results and experimental results from real-world applications.

The pandemic crisis has accelerated the process of digital transformation in museums. The introduction of innovations in the area of communication and processes of providing museum services to visitors has practically demonstrated its usefulness. By defining the critical variables of the digital transformation process for museums, we confirmed the hypothesis that visitor orientation mediates the relationship between the communication system and process innovations. Our research was conducted on 200 Polish museums using the SEM methodology. Studying the role of visitor orientation in museums highlights the institution's mission and relationship with digital transformation. This also contributes to the developing knowledge about game changers and presents a new game-changer in the digital transformation process for cultural institutions. Our considerations align with contingency theory and provide a better understanding of how internal factors (such as visitor orientation) under special external conditions can affect the digital transformation process.

This study investigates how health influencers (HIs) and medical professionals (MPs) use epistemic stance to shape menopause treatment discourse on YouTube, a popular platform for digital health communication. Using a corpus-assisted approach, it analyzes mental and communication verbs controlling (that-)complement clauses across the two speaker groups. The quantitative results show that both HIs and MPs frequently express certainty, with HIs favoring speculative mental verbs (e.g. think, believe) and MPs predominantly relying on reporting verbs (e.g. state, explain). Further qualitative analysis reveals divergent stance-taking strategies: HIs combine subjective viewpoints with information to build emotional connections and solidarity, while MPs adopt an authoritative stance, channeling external evidence to establish credibility. The findings expound the dangers of health disinformation, as HIs tend to base claims on personal beliefs rather than scientific facts, potentially misleading viewers. To address this, MPs should prioritize clear, evidence-based communication and develop interactive strategies to engage online audiences effectively. The study foregrounds the tension between building trust and audience engagement, calling for improved digital literacy to critically assess online health content and the persuasive discursive strategies employed by influencers. Its insights contribute to understanding epistemic stance in digital health communication and offer some recommendations for mitigating misinformation. [ABSTRACT FROM AUTHOR]

Background: Empathy and communication are critical abilities for nursing students, and in recent years, scenario-based teaching has played a crucial role in fostering empathy and professional skill development. However, novice nursing students in basic nursing education often lack prior experience in patient communication, making it challenging for them to prepare adequately for scenarios and effectively handle difficulties in real-life situations. This deficiency also hampers participants' or observers' ability to engage in deep reflection, feedback, and learning. Consequently, students frequently experience anxiety in patient communication, and the effectiveness of empathy building remains limited. The aim of the study was to use empathy mapping and mini-simulation in learning to enhance nursing students' empathy and self-confidence in communication. Methods: A prospective quasi-experimental research design was employed, targeting second-year students in the four-year nursing program at our institution, specifically in the Basic Nursing and Experimentation II class. The students were randomly divided into two groups: an experimental group and a control group, with a total of 98 students (52 in the experimental group and 46 in the control group). The experimental group received instruction using empathic communication digital materials and engaged in empathy mapping exercises, while the control group underwent conventional scenario-based teaching. Pre-test and post-test data were collected from both groups. Results: A total of 98 students participated in the study, with 46 students in the control group and 52 students in the experimental group. The average age of the participants was 19.19 ± 0.53 years, with a predominance of females (82.7%). At the end of the semester, there was no significant difference in the average empathy levels between the two groups. However, the communication confidence levels of students in the control group (40.20 ± 6.54) were significantly lower than those in the experimental group (43.88 ± 6.35) (P = 0.006). Conclusions: This teaching approach facilitated deeper and broader student learning, enhancing both empathy and communication confidence. The teaching materials developed in this study can be employed in future courses to teach empathy and patient communication effectively. [ABSTRACT FROM AUTHOR]

Holographic multiple-input multiple-output (MIMO) method leverages spatial diversity to enhance the performance of wireless communications and is expected to be a key technology enabling for high-speed data services in the forthcoming sixth generation (6G) networks. However, the antenna array commonly used in the traditional massive MIMO cannot meet the requirements of low cost, low complexity and high spatial resolution simultaneously, especially in higher frequency bands. Hence it is important to achieve a feasible hardware platform to support theoretical study of the holographic MIMO communications. Here, we propose a near-field holographic MIMO communication architecture based on programmable digital coding metasurface (PDCM) and electromagnetic theory. The orthogonal holographic patterns on the transmitting and receiving apertures are firstly obtained using the Hilbert-Schmidt decomposition of the radiation operator. Then the information to be transmitted is pre-encoded on PDCM following the principle of direct digital modulations. A PDCM-based holographic MIMO prototype is designed and experimentally verified in microwave frequencies. The measured results of constellations show that the prototype can realize dual-channel signal transmissions under quadrature-phase shift keying scheme. The proposed paradigm features low complexity, low cost and low power consumption, and may become a valuable technique in beyond fifth generation and 6G wireless communications. A dual-channel near-field holographic MIMO communication scheme is proposed and experimentally verified by using programmable digital coding metasurface and electromagnetic theory, which provides a low complexity, low cost and low power consumption solution to fully utilize the spatial diversity and serves as a valuable technique in beyond fifth generation and 6G wireless communications.

Cloud Computing (CC) is a fast emerging field that enables consumers to access network resources on-demand. However, ensuring a high level of security in CC environments remains a significant challenge. Traditional encryption algorithms are often inadequate in protecting confidential data, especially digital images, from complex cyberattacks. The increasing reliance on cloud storage and transmission of digital images has made it essential to develop strong security measures to stop unauthorized access and guarantee the integrity of sensitive information. This paper presents a novel Crayfish Optimization based Pixel Selection using Block Scrambling Based Encryption Approach (CFOPS-BSBEA) technique that offers a unique solution to improve security in cloud environments. By integrating steganography and encryption, the CFOPS-BSBEA technique provides a robust approach to secure digital images. Our key contribution lies in the development of a three-stage process that optimally selects pixels for steganography, encodes secret images using Block Scrambling Based Encryption, and embeds them in cover images. The CFOPS-BSBEA technique leverages the strengths of both steganography and encryption to provide a secure and effective approach to digital image protection. The Crayfish Optimization algorithm is used to select the most suitable pixels for steganography, ensuring that the secret image is embedded in a way that minimizes detection. The Block Scrambling Based Encryption algorithm is then used to encode the secret image, providing an additional layer of security. Experimental results show that the CFOPS-BSBEA technique outperforms existing models in terms of security performance. The proposed approach has significant implications for the secure storage and transmission of digital images in cloud environments, and its originality and novelty make it an attractive contribution to the field. Furthermore, the CFOPS-BSBEA technique has the potential to inspire further research in secure cloud computing environments, making the way for the development of more robust and efficient security measures.

This study aims to assess the level of network communication culture among teachers and students to determine their abilities and skills in the field of network communications. Structured questionnaire surveys were utilized as one of its primary methods for data collection in this study. The data obtained confirms the widespread recognition of digital technologies among students and teachers. The high level of internet usage among students (70%) and active engagement in online chats (73%) underscores the significance of access to online resources and various communication tools in the educational process. Educators also actively utilize digital tools, although some report low (10%) or moderate (25%) levels of knowledge and express a need for additional training and support. The results emphasize the importance of effective time and resource management for teachers, as well as the convenience and accessibility of digital tools for students. Some students suggest replacing face-to-face contact with digital tools and emphasize the importance of interpersonal communication. The attained results can be integrated into the existing knowledge framework within the domains of education, psychology, pedagogy, information technology, and sociology, thereby facilitating a deeper understanding of the impact of digital technologies on educational processes.

This study introduces a design transformation model for AI-generated Chinese traditional architectural images (SD Lora&Canny) based on Stable Diffusion (SD). By integrating parameterization techniques such as Low-Rank Adaptation (Lora) and edge detection algorithms (Canny), the model achieves precise restoration of the architectural form, color elements, and decorative symbols in Chinese traditional architecture. Using the Beijing Drum Tower as the experimental subject, statistical analysis software (SPSS V28.0) was employed to conduct a quantitative evaluation and comparative analysis of architectural images generated by the DALL-E, MidJourney, SD, and SD Lora&Canny models. The results demonstrate that the SD Lora&Canny model significantly outperforms traditional generation tools in restoration accuracy and visual fidelity. Finally, this study applied the SD Lora&Canny model to create the digital cultural product AR Drum and Bell Tower Fridge Magnet, showcasing its practical application in digital cultural creation and verifying its innovative potential in the digital preservation and transmission of Chinese traditional architecture.

In light of the issues associated with the laying process of transmission line cables, including concealed security risks and contact collisions between pulleys and cables, which primarily stem from reliance on drawings, this paper introduces a simulation methodology for the cable laying construction process utilizing Building Information Modeling (BIM) technology. Initially, two-dimensional DWG graphic data are employed to develop a model of the target equipment and construction environment using BIM software (Solid works 2020). Subsequently, the cable is accurately modeled by applying ADAMS virtual prototype technology, the bushing force connection method, and the macro command language. This allows for the construction of a three-dimensional real cable laying system for transmission lines, enabling the simulation of the dynamic cable laying process in the field. Subsequently, an error analysis is conducted to compare the axial tension and laying speed of the cable with theoretical calculation values. The study then proceeds to analyze tension fluctuations during the cable laying process and assess the load-bearing capacity of the pulleys, thus facilitating effective control of the construction process and enhancing safety measures. The findings indicate that the proposed method can accurately and efficiently simulate the on-site cable laying construction process, with numerical errors maintained below 5%, thereby validating the integrity of the model. Furthermore, the traction overload safety protection amplification coefficient is determined to be α = 1.5. It is highlighted that the bearing capacity of the block must exceed 60% of the load carried by the conductor at constant speed. This research provides a theoretical foundation for addressing safety hazards in cable laying engineering and holds certain engineering value. [ABSTRACT FROM AUTHOR]

This paper explores a specific class of equations that model the propagation of optical pulses in dual-core optical fibers. The decoupled nonlinear Schrödinger equation with properties of M fractional derivatives is considered as the governing equation. The proposed model consists of group-velocity mismatch and dispersion, nonlinear refractive index and linear coupling coefficient. Different types of solutions, including mixed, dark, singular, bright-dark, bright, complex and combined solitons are extracted by using the integration methods known as fractional modified Sardar subequation method and modified F-expansion method. Optical soliton propagation in optical fibers is currently a subject of great interest due to the multiple prospects for ultrafast signal routing systems and short light pulses in communications. In nonlinear dispersive media, optical solitons are stretched electromagnetic waves that maintain their intensity due to a balance between the effects of dispersion and nonlinearity. Furthermore, hyperbolic, periodic and exponential solutions are generated. A fractional complex transformation is applied to reduce the governing model into the ordinary differential equation and then by the assistance of balance principle the methods are used, depending upon the balance number. Also, we plot the different graphs with the associated parameter values to visualize the solutions behaviours with different parameter values. The findings of this work will help to identify and clarify some novel soliton solutions and it is expected that the solutions obtained will play a vital role in the fields of physics and engineering.

Multiple digital communication devices provide varying capabilities and processes for self-disclosure, surveillance, and privacy management, therefore eliciting a variety of user privacy perceptions and behaviours. Drawing from the media mastery framework and the comparative privacy research framework, this study investigates similarities and differences in online privacy outcomes associated with computer and mobile phone use via content analysis of 12 focus groups conducted with US college students in 2006 and 2016. Findings reveal similarities and differences across device type and time and their combinations among selected privacy-related codes from the media mastery framework. Cluster analysis of the codes reveals several general themes such as crossing the boundary from private to public, and safety and trust. Contributions include the use of a reliable conceptual foundation for categorising online privacy boundary phenomena, the generation of discussions about these phenomena from a goal-free evaluation approach, and comparisons across devices and time. The discussion provides theoretical and practical implications. [ABSTRACT FROM AUTHOR]

This paper discusses the multifaceted phenomena of time and temporality in smartphone-based communication as a central dimension of communicative and social experience in mediatized and mobilized societies. Although temporal aspects have traditionally been considered in the linguistic study of digital media, there is a notable lack of research explicitly addressing temporal practices, i.e. the temporal agency, of participants in digital communication. The Swiss research project "Texting in Time" investigates these practices using screen capture videos, providing a detailed and immersive view of participants' smartphone-based interactions. This methodological approach allows for the analysis of various processual phenomena of digitally written communication—from message construction to patterned multi-participation in simultaneous chats. The project examines these dynamics by developing a scalar view of temporalities. Large-scale analyses reveal the temporal patterns structuring everyday smartphone use during days and weeks, while small-scale analyses provide insights into the moment-to-moment organization of digital interactions within minutes and seconds. This paper, by showcasing both analytical perspectives, underscores the significance of revisiting the concept of temporality in digitally mediated interactions, offering relevant insights for advancing our understanding of contemporary mobile communication in linguistic research. • The article introduces the research project "Texting in Time" that collects screen captures of smartphone communication. • The article examines digital communication across small and large temporal scales, highlighting daily and in-the-moment patterns. • The article explores temporal agency in managing digital rhythms, balancing medium constraints, affordances, and ideologies shaping social norms.

The pseudo-random number generator (PRNG) based on chaos has been widely used in the fields of digital communication, cryptography and computer simulation. In this paper, we study a new PRNG based on spatial surface chaotic system (SSCS), which is constructed based on coupling mapping lattice (CML) and one-dimensional Logistic chaotic map. To verify the performance of this generator, we study its nonlinear dynamic properties, including the Lyapunov exponent, ergodicity and bifurcation phenomena. Moreover, we analyze the cryptographic properties such as key space, key sensitivity, correlation, histogram and information entropy, while performing NIST SP800-22 test and TestU01 test for the randomness of this system. Theoretical analysis and numerical simulation results show that the PRNG proposed in this paper has good complexity, ergodicity, sensitivity and randomness. Moreover, the key space can increase dynamically with the increase of encrypted data, especially suitable for the protection of big data such as multimedia, which is more advantageous than most existing chaotic mapping. The results of this paper will provide a new idea for the study of chaotic cryptography, and motivate the study of new discrete chaotic models with desirable statistical properties.

This paper presents a new high-speed black and white image transmission across Free Space Optics (FSO) system utilizing Orbital Angular Momentum (OAM) multiplexing. The system is designed to simultaneously transmit four distinct black and white images (trees, cameraman, lighthouse, and peppers), each modulated onto a separate OAM beam ($LG_0^0$ L G 0 0 , $LG_0^{15}$ L G 0 15 , $LG_0^{45}$ L G 0 45 , and $LG_0^{75}$ L G 0 75 ) at a rate of 10 Gbps, demonstrating the feasibility of parallel transmission of digital images. The system performance is evaluated over different weather conditions including Clear Air (CA), different fog levels, and real-world meteorological data from Riyadh city, Kingdom of Saudi Arabia (KSA). A median filtering technique is applied to improve image quality, leading to notable enhancements in Signal-to-Noise Ratio (SNR), Peak Signal-to-Noise Ratio (PSNR), and Structural Similarity Index (SSIM). The system successfully supports the transmission over a 16 km in CA weather and 10 km link under Riyadh weather conditions. At these ranges, SNR, PSNR, and SSIM are greater than 6.05 dB, 11.54 dB, and 0.56, respectively. This study underscores the potential of using OAM-based FSO systems for high-speed, real-time remote monitoring, particularly in adverse atmospheric environments. [ABSTRACT FROM AUTHOR]

The development of dual‐mode organic photodetectors (OPDs) greatly improves its functionality by enabling selective spectral detection. This study presents a unidirectional bias‐switchable dual‐mode OPD that leverages selective carrier extraction through the manipulation of light field distributions and non‐equilibrium transport dynamics. This dual‐mode OPD features a simple single‐layer structure, allowing for straightforward one‐sided light incidence and without the need for voltage polarity switching. By optimizing the blend of poly(4‐butyl‐phenyl‐diphenyl‐amine) and non‐fullerene acceptor Y6, the device achieves efficient single‐band detection of ultraviolet (UV) light at low bias and dual‐band detection of UV and near‐infrared light at high bias. This versatility not only streamlines device architecture but also facilitates secure optical communication and gesture simulation, making it a valuable tool for advancing organic optoelectronics. The proposed strategy demonstrates universal applicability, paving the way for enhanced security and functionality in digital communication systems. [ABSTRACT FROM AUTHOR]

If social media are generally considered workplace distractions, how does Meta promote their enterprise social medium, Workplace? Analyzing Meta's corporate communication, I explore their emphasis on "connectivity" as Workplace's key selling point, aligning with existing research on Meta's self-construction. Highlighting three pertinent themes in the corporate communication, I explore how Workplace is promised to (1) subsume the gray media of corporate life (2) turn companies into communities where workers share information boundlessly, even about their personal lives and (3) that these streams of communicative data are ultimately used as a datafied proxy for corporate health via Workplace. I propose that the productivity claimed to result from Workplace's connectivity hinges on a subtle merging of personal and professional aspects in employees' lives, which is in line with broader Silicon Valley trends and Meta's own organizational image. I discuss the implications and limitations of these findings. [ABSTRACT FROM AUTHOR]

It specifically examines the case of the Basilica Cistern/Istanbul, analysing social media interactions post-restoration. Design/methodology/approach: Using newspaper archive scanning and survey technique, this study observed public content on Instagram focusing on the post-restoration period of the Basilica Cistern. 406 (283 valid) people who visited the Cistern and shared their experiences on Instagram between August 2022 and January 2023 participated in a survey. The analysis utilized Python for advanced correlation studies, enabling an in-depth exploration of the interplay between architectural features and social media sharing behaviours. Findings: The analysis revealed that historical significance, lighting elements, role as a photographic backdrop significantly influenced sharing behaviours. Correlations were found between specific spatial features of the cistern and various sharing motivations, such as communication with people, personal gain, and popularity. The study highlights a diverse spectrum of motivations among users, emphasizing the relationship between these motivations and spatial features. Research limitations/implications: This study underscores the necessity for further inquiry into the intricate dynamics among digital communication, architectural spaces, and user motivations. Limitations include potential challenges in gathering data from social media due to concerns of cyber fraud and the misuse of hashtags. Originality/value: This research offers novel insights into the interplay between digital communication and architecture. It underscores the potential of digital platforms as valuable data sources for architectural theorizing and practice, particularly in understanding how restorations and architectural changes are perceived and discussed in the digital space.

Purpose: In response to the COVID-19 pandemic, many employees had to switch to remote work. While some adjusted successfully to this transition, others have struggled. Leveraging information systems (IS) to adjust to major exogenous shocks is called digital resilience. The purpose of this paper is to understand what we can learn about employees' digital resilience from externally enforced transitions to remote work. Design/methodology/approach: As digital resilience is challenging to measure, this study uses an embedded mixed methods approach. The authors conducted a qualitative analysis of 40 employees' statements on their remote work experience during the first six months of the pandemic and complemented these findings with scale-based digital resilience scores. Findings: The authors find that employees' digital resilience largely depends on the amount of technical equipment and support they receive from their organizations as well as their ability and willingness to learn how to adequately use and communicate through information and communication technologies. Being self-disciplined and self-responsible positively affects digital resilience, while social isolation threatens it. Organizations can foster digital resilience building by encouraging digital networking, building a digital culture and netiquette, and treating digital resilience as a sociotechnical phenomenon. Originality/value: This is one of the first empirical studies of digital resilience on a human level. It sheds light on the missing link between IS-enabled resilience and transitions to remote work. Specifically, it provides original insights into its development and manifestation in a remote work context during the COVID-19 pandemic. For researchers, it provides novel guidance on choosing appropriate measurement instruments to capture digital resilience. [ABSTRACT FROM AUTHOR]

Managing the complex relationship between digitalization and sustainable development is a key challenge for many small and medium sized enterprises (SMEs). To understand strategies of forerunners in the field of digital platforms and platformization, this study performs a cross‐case analysis of three sustainability‐oriented SMEs employing multi‐sided platforms operating in three sectors (wholesale, information and communication technology, and construction) in Germany. The integrated analysis framework draws from Belief‐Action‐Outcome theory, multi‐sided platform strategies, and the sustainable development goals (SDG). The findings identify four platformization strategies and exemplarily specify contributions to SDG 2, 7, 8, 9, 12, 13, and 17. The proposed socio‐eco‐technical framework emphasizes linkages between an employed platformization strategy (technical system), the corporate culture (social system), the platform stakeholders and the SDGs (ecological system). A seven‐step approach is proposed to motivate and facilitate the development and continuous improvement of platformization for sustainability in SMEs. [ABSTRACT FROM AUTHOR]

Acoustic communication is an important aspect of life for marine mammals, as their environment often limits the reliability of visual cues. However, there is little information regarding the acoustic communication and behavior of Australian snubfin dolphins (Orcaella heinsohni). This study was designed to determine if call rate and type were significantly affected by the behavioral state, group size, and cohesion of snubfin dolphins in the Fitzroy River in Queensland, Australia. We found that dolphins significantly modified both call rate (calls/hour/individual) and call type among behavioral states. For example, call rates were higher when dolphins were foraging versus resting or traveling. We also found that group size and cohesion had minimal effects on call rate, but significantly affected the predicted probabilities of call type production. For example, the probability ratio of burst pulse to whistle production is estimated to be highest when groups are widespread (>10 m), indicating the potential importance of burst pulses in maintaining contact between dispersed individuals. This study presents the first comprehensive analysis of snubfin dolphin communication under natural noise conditions in relation to behavioral context, which provides a foundation to explore how anthropogenic acoustic masking and behavioral disturbances may affect these dolphins in the future.

This research examines the influence of CEO versus brand communication on public engagement and digital activism during the Russia–Ukraine war. Brand communication refers to messages sent out through an organization's social media accounts, whereas CEO communication comes from the executive's personal account. The authors depart from an analysis of 236,119 tweets investigating the effects of message sender (CEO vs. brand), message framing (self vs. other), and message appeal (informational vs. emotional) on engagement (i.e., likes, retweets, and replies). To further understand, they subsequently deploy a 2 × 2 between-subjects design (N = 608) that introduces scenarios where either a CEO or brand proposes a public policy campaign, advocating support for U.S. citizens (self framing) or Ukrainian civilians (other framing). Key findings reveal that CEO communications foster greater engagement and digital activism than brand messages. CEO communication that merges self framed with informational appeals or other framed with emotional appeals outperforms brand messages regarding public engagement. In addition, CEO campaigns centered on Ukrainian civilians amplify digital activism, mirroring findings when brands approach the war's implications for U.S. citizens. Together, these insights unveil the intricate dance of message sender, framing, and appeal during global geopolitical events, providing vital knowledge for organizations and policy makers aiming to optimize public backing in times of war.

Purpose: One of the insidious effects of government and business imposter scams is the potential erosion of trust among defrauded consumers. This study aims to assess the relationship between prior imposter scam victimization and present ability to discriminate between real and fake digital communications from government agencies and retail companies. Design/methodology/approach: This paper tests whether a short, interactive training can help consumers correctly identify imposter scams without mistrusting legitimate communications. Participants were randomized into one of two control groups or to one of two training conditions: written tips on identifying digital imposter scams, or an interactive fraud detection training program. Participants were tested on their ability to correctly label emails, websites and letters as real or a scam. Findings: This paper find that prior imposter scam victimization is not associated with greater mistrust. Compared to the control conditions, both written tips and interactive digital fraud detection training improved identification of real communications and scams; however, after a two- to three-week delay, the effect of training decreases for scam detection. Originality/value: Results indicate that prior imposter scam victimization is not associated with mistrust, and that one-time fraud detection training improves consumers' detection of imposter scams but has limited long-term effectiveness.

Drawing upon Person-Environment fit (PE fit) theory, this paper attempts to explore the determinants of digital leadership and its interactions between personal and environmental dimensions, including organizational, interpersonal and external dimensions, in South Korea. As Remote Work (RW) and Digital Transformation (DT) have been discussed since the start of the COVID-19 pandemic, this research focuses upon the concept of digital leadership, which can effectively cope with both RW and DT. To help Human Resource (HR) practitioners support digital leadership, this paper employs the fuzzy-Decision Making Trial and Evaluation Laboratory (f-DEMATEL) method. Through the convenience sampling method, we collected data sets from HR specialists in large South Korean firms. Our findings indicate that the organizational culture that covers digital supportive culture in the organizational dimension is the most crucial, influencing the elements in the personal dimension (e.g. new working systems, communication and acceptance of digital technologies). In contrast, the factor of capabilities in the personal dimension is the only factor affecting organizational structure and agility in the organizational dimension. Thus, we conclude that both the organizational and personal dimensions can uniquely interact with each other when actualizing digital leadership in South Korea. [ABSTRACT FROM AUTHOR]

In response to significant societal challenges, there is a growing demand for scientists to actively engage in public discussions. The recent Covid-19 pandemic led to the sudden visibility of certain scientists, necessitating them to extend their roles beyond research and actively communicate with the general public. Online platforms allow for direct engagement but increase the challenge by interconnecting different public arenas. Our case study examined the role performance of visible virologists on Twitter/X in six different time periods during the pandemic in Germany (N = 1003). Findings indicate that they often express calls to action, and voice their own views, but seldom address uncertainty. Differences over time were found in their use of different types of statements, scientific jargon and emotional language. They also utilised the opportunities of direct communication, performing roles like watchdogs or advocates, highlighting the importance for scientists to reflect on their roles as communicators.

The proliferation of crimes on social media platforms presents an increasingly complex challenge for society, demanding rigorous analysis and innovative solutions. This paper examines the potential of forensic linguistics in investigating and uncovering language crimes on social media. It explores how forensic linguistic approaches can systematically analyze the linguistic structures--from words to discourses--that constitute criminal communication in digital spaces. Through qualitative research employing document analysis, observation, and note-taking techniques on social media content, five distinct patterns of criminal language use were identified: (1) body shaming, involving insults directed at physical appearance; (2) defamation and libel against individuals and groups; (3) hate speech; (4) threats targeting specific parties or groups; and (5) incitement through the dissemination of false information about interlocutors. These patterns provide valuable insights into crimes that often elude conventional investigative methods. The study demonstrates that forensic linguistic approaches offer promising avenues for case resolution, providing government agencies and relevant institutions with effective tools to address the challenges posed by language crimes on social media platforms. This research contributes to the growing body of knowledge on digital criminology and highlights the critical role of linguistic analysis in navigating the complexities of online criminal behavior.

In research into interorganizational collaboration (IOC), the number of contributions highlighting the constitutive role of communication constantly seems to increase. However, surprisingly few contributions are devoted to communication studies that concentrate on the use of different media. An advanced "mediatedness" perspective is increasingly required, not least in terms of theory, focusing on how different media, as objects, tools and agents altogether constitute collaboration through complex combinations and asymmetric usage patterns. Therefore, the purpose of this article is to develop a theoretical framework for analyzing IOCs as media-driven processes and practices, which is highly relational. Of particular importance are the diachronic transformations of meaning-making when discursive content (sketchy notes, brainstorming, digital threads, presentation program slides, etc.) is transferred and materialized into stable ideas, proposals or solutions; moving from one media context to another; and its impact on the collaborations' outcome.

This paper is mainly concerning the study of truncated M-fractional Kuralay equations that have applications in numerous fields, including nonlinear optics, ferromagnetic materials, signal processing, engineering fields and optical fibers. Due to its ability to clarify a wide range of sophisticated physical phenomena and reveal more dynamic structures of localized wave solutions, the Kuralay equation has captured a lot of attention in the research field. The newly designed integration methods, known as the modified Sardar subequation method and enhanced modified extended tanh expansion method are used as solving tools to validate the solutions. The goal of this study is to extract several kinds of optical solitons, such as mixed, dark, singular, bright-dark, bright, complex and combined solitons. Due to the many potential applications for superfast signal routing techniques and shorter light pulses in communications, the optical propagation of soliton in optical fibers is now a topic of significant interest. In nonlinear dispersive media, optical solitons are stretched electromagnetic waves that maintain their intensity due to a balance between the effects of dispersion and nonlinearity. In addition, exponential, periodic, hyperbolic solutions are generated. The applied approaches are efficient in explaining fractional nonlinear partial differential equations by providing pre-existing solutions and also producing new solutions by combining results from multiple processes. Additionally, we plot the contour, 2D, and 3D graphs with the associated parameter values to visualize the solutions. The results of this study show the effectiveness of the approaches adopted and help enhance comprehension of the nonlinear dynamical behavior of specific systems. We expect that a substantial amount of engineering model specialists will greatly benefit from our work. The findings demonstrate the efficacy, efficiency, and applicability of the computational method employed, particularly in dealing with intricate systems. [ABSTRACT FROM AUTHOR]
