This study differentiates the roles of telepresence and transportation, the two widely cited processes underpinning an immersive media viewing experience, in the context of virtual marketing. In ...Study 1, college students viewed a real estate property tour in virtual reality (VR; high immersion) or as a 360° video (low immersion) in a research lab. The tour was accompanied by a voiceover presenting descriptive information about the apartment (descriptive evidence) or a narrative‐based introduction (narrative evidence). We found the enhanced telepresence under the VR viewing condition negatively impacted users' memory of the property; this effect was particularly pronounced with the narrative voiceover. Study 2 replicated key findings from Study 1 in an online experiment with a larger and more diverse sample. We also found that narrative‐induced transportation strengthened attitudinal outcomes, and enhanced telepresence boosted this effect. Our studies disentangle the impacts of VR‐induced telepresence on cognitive processing from the effects of narrative‐induced transportation on persuasive outcomes. The highly immersive media experience combined with deep transportation into the narrative can strengthen viewers' positive attitude towards the overall experience but hinder their ability to remember the details of the content. The findings point to a medium‐message matching strategy to achieve marketing goals.
Abstract
At a time when nearly all social activities could be, and likely are, mediated in some ways by some forms of computing technology, what should be the focus of CMC research? How do we ...theorize and study computer-mediated (or should we say digitally-mediated) communication when the topics of our research—the technology, the concepts and processes of mediation, our sense of what constitutes communication, as well as the theories and methods used to examine these—are all in flux? Early in the spring of 2018, the Journal of Computer-Mediated Communication invited scholars to submit ideas for a dedicated issue to consider these questions. The collection of meta-theoretical discussions, literature reviews/analyses, and concept explications included in this special issue will point to a general direction and offer a launching point for theory construction and systematic research in a continuously evolving field.
A survey of 2,095 college students in five major cities in China was conducted to examine the influence of personality, parental behaviors, and self-esteem on Internet addiction. We found that ...psychoticism and neuroticism were both positively related to Internet addiction. The influence of parental behaviors on Internet addition was also significant. However, fathers' and mothers' behaviors had different impacts on their children's likelihood of being addicted to the Internet. Specifically, we found that fathers' rejection and overprotection, and mothers' rejection would increase the risk for Internet addiction. Furthermore, the influence of emotional warmth from parents on Internet addiction was partially mediated by self-esteem. Finally, we found that parental behaviors of mothers and fathers affected males and females differently in terms the risk of being addicted to the Internet.
Destress blasting is a rockburst control technique where highly stressed rock is blasted to reduce the local stress and stiffness of the rock, thereby reducing its burst proneness. The technique is ...commonly practiced in deep hard rock mines in burst prone developments, as well as in sill or crown pillars which become burst-prone as the orebody is extracted. Large-scale destressing is a variant of destress blasting where panels are created parallel to the orebody strike with a longhole, fanning blast pattern from cross cut drifts situated in the host rock. The aim of panel destressing is to reduce the stress concentration in the ore blocks or pillars to be mined. This paper focuses on the large-scale destress blasting program conducted at Vale’s Copper Cliff Mine (CCM) in Ontario, Canada. The merits of panel destressing are examined through field measurements of mining induced stress changes in the pillar. The destressing mechanism is simulated with a rock fragmentation factor (α) and stress reduction/dissipation factor (β). A 3D model is built and validated with measured induced stress changes. It is shown that the best correlation between the numerical model and field measurements is obtained when the combination of α and β indicates that the blast causes high fragmentation (α = 0.05) and high stress release (β = 0.95) in the destress panel. It is demonstrated that the burst proneness of the ore blocks in the panel stress shadow is reduced in terms of the brittle shear ratio (BSR) and the burst potential index (BPI).
The present study examines the short-term cognitive effects of playing a sexually explicit video game with female “objectification” content on male players. Seventy-four male students from a ...university in California, U.S. participated in a laboratory experiment. They were randomly assigned to play either a sexually-explicit game or one of two control games. Participants’ cognitive accessibility to sexual and sexually objectifying thoughts was measured in a lexical decision task. A likelihood-to-sexually-harass scale was also administered. Results show that playing a video game with the theme of female “objectification” may prime thoughts related to sex, encourage men to view women as sex objects, and lead to self-reported tendencies to behave inappropriately towards women in social situations.
The “privacy calculus” approach to studying online privacy implies that willingness to engage in disclosures on social network sites (SNSs) depends on evaluation of the resulting risks and benefits. ...In this article, we propose that cultural factors influence the perception of privacy risks and social gratifications. Based on survey data collected from participants from five countries (Germany n = 740, the Netherlands n = 89, the United Kingdom n = 67, the United States n = 489, and China n = 165), we successfully replicated the privacy calculus. Furthermore, we found that culture plays an important role: As expected, people from cultures ranking high in individualism found it less important to generate social gratifications on SNSs as compared to people from collectivist-oriented countries. However, the latter placed greater emphasis on privacy risks—presumably to safeguard the collective. Furthermore, we identified uncertainty avoidance to be a cultural dimension crucially influencing the perception of SNS risks and benefits. As expected, people from cultures ranking high in uncertainty avoidance found privacy risks to be more important when making privacy-related disclosure decisions. At the same time, these participants ascribed lower importance to social gratifications—possibly because social encounters are perceived to be less controllable in the social media environment.
High magnitude seismic events (HMSE), also called major events, triggered at underground mines can severely threaten safety and structures in mines. The aims of this work are to assess stress ...evolution with the occurrence of them and identify patterns in stress change. Several methods were used to help understand the stress redistribution and rock mass behavior related to two HMSE with moment magnitude greater than 1.0 in a deep nickel mine. Approximately 46,500 seismic events were compiled with 2 HMSE at this mine and used seismic tomography to obtain high-resolution images and temporal-spatial velocity changes before and after these events. This work exhibited surrounding stress evolution and geological structures. Seismic imaging results show that velocity increased in the nearby regions of HMSE before they were triggered. Stress subsequently reduced in the relaxation process after the occurrence of HMSE. Conversely, regions predominantly occupied by low-velocity anomalies increased to higher stress levels after HMSE. Overall, the stress redistributed toward an equilibrium state following HMSE. This study highlights the value of utilizing seismic tomography for estimating stress evolution associated with HMSE. The findings illuminate the applications of seismic imaging around HMSE of hard-rock mines, providing insights into seismic hazard mitigation for deep mining.

Searching for and accessing online information through search engines causes digital media users to become overconfident in their own knowledge – in a sense, to attribute online knowledge to ...themselves. If searching the internet via search engine leads people to conflate digital information as self-produced, what happens when features of our devices turn information search into an interpersonal situation? The proliferation of anthropomorphic technology underpinned by artificial intelligence (AI) may challenge the current view of search-induced cognitive overconfidence. In two experiments, we investigate how using digital agents to search for information moderates the misattribution of online information to one’s own memory. We find that, in contrast to using a search engine, using a digital agent to access online information does not lead to higher estimations of cognitive self-esteem (Experiment 1). Moreover, using a humanized digital agent may lead to lower cognitive self-esteem than using a non-humanized digital agent or thinking alone (Experiment 2). Whereas internet searches can make people overconfident in their cognitive abilities, accessing information through a conversational digital agent appears to clarify boundaries between internal and external knowledge.
