Result from a between-subjects experiment (N = 50) examines that there are interaction effects between users personality and number of voice on social attraction and trust toward media technology which are critical in humancomputer interactions. In this experiment, extrovert users feel a stronger feeling of social attraction and trust when there is one identical voice from several smart devices. On the other hand, introvert users feel a stronger feeling of social attraction and trust when different smart devices make respective voices. These results provide a strong evidence for human's automatic social response to smart devices which have a voice, a strong anthropomorphic cue. Finally, we discuss on implications for future VUI setting, according to user's personality.

Effective Cross-cultural Advertising: Moderating Roles of Ethnic Identity and Religiosity in Pitching Controversial Vs. Non-controversial Products to Diasporic Communities

Our study explores the effectiveness of cross-cultural advertising and investigates the effectiveness of advertisements. In this experimental study, a national sample (N = 252) was recruited with an equal number of Indian and Middle Eastern subjects, which were randomly chosen across the United States. The results reflect that attitude formation patterns for Indians and Middle Easterners are dissimilar when they are exposed to advertisements containing actors with varied ethnicities

This study examines players' affordances and investigate how they influence user experience in ARG. It explores how affordances are perceived and enacted by users in an augmented environment to maximise user experience of ARG. A multimethod research approach was utilised that integrated ethnographic and statistical methods. Qualitative study confirmed the general structure of affordance framework, while also revealing relational structures with other variables to explore. Based on the affordance factors identified from the ethnographic methods, a survey questionnaire was created to map and investigate the effects of affordance on the user's cognitive processes and the influence of affordance on the gameplay process. The results show that technological properties of the ARG system affect opportunities for action available in the environment (affordances). The heuristic role of immersion and presence affordances through underlying cues appear to trigger a player's sensory representations of affective affordances.

Algorithm systems such as chatbots can play an important role in assessing a user's credibility on algorithms. Unless users believe the chatbot's information is credible, they are not likely to be willing to act on the recommendation. This study examines how literacy and user trust influence perceptions of chatbot information credibility. Results confirm that algorithmic literacy and users' trust play a pivotal role in how users form perceptions of the credibility of chatbot messages and recommendations. Insights on how user trust is related to credibility provide a useful perspective on the conceptualization of algorithmic credibility. Algorithmic information processing that has been identified provides better foundations for algorithm design and development and a stronger basis for the design of sense-making chatbot journalism.

Despite the surging popularity of AI, how users evaluate algorithms, how people perceive algorithmic decisions, and how they relate to algorithmic functions remain largely unexplored. Invoking the idea of embodied cognition, we characterize core constructs of algorithms that drive the value of embodiment and conceptualizes these factors in reference to trust by examining how they influence the user experience of personalized recommendation algorithms. The findings elucidate the embodied cognitive processes involved in reasoning algorithmic characteristics-fairness, accountability, transparency, and explainability-with regard to their fundamental linkages with trust and ensuing behaviors. Users use a dual-process model, whereby a sense of trust built on a combination of normative values and performance-related qualities of algorithms. Embodied algorithmic characteristics are significantly linked to trust and performance expectancy. Heuristic and systematic processes through embodied cognition provide a concise guide to its conceptualization of AI experiences and interaction. The identified user cognitive processes provide information on a user's cognitive functioning and patterns of behavior as well as a basis for subsequent metacognitive processes. Keywords Algorithm experience; embodied cognition; enactive algorithm; explainability; heuristic and systematic process; human-artificial intelligence interaction Algorithms are continuously shaping the everyday lives of billions of people. Although algorithms are growing ever more pervasive, powerful and sophisticated, algorithms themselves are literal-minded, and context and nuance often elude them [1]. Algorithm designs are a reflection of user values, priorities and preferences, but they are not always ideal, not always neutral, and human biases can affect the algorithms [2]. Algorithms based on machine learning tend to bear serious risks, making it important to ensure that these algorithms are not biased towards any gender, race, ethnicity or other sensitive variables [3]. These concerns are related to recent debates on fairness, accountability, transparency and explain-ability (FATE), which are intrinsically embedded into the contemporary algorithmic technologies [4]. Issues as to what can be done to ensure the decisions made by algorithms are fair, transparent, ethical, and do not discriminate remain unre-solved and require continuing deliberation [5, 6]. Given that such algorithmically informed decisions have the potential for significant societal impact, these issues continue to evolve and ensuring challenges will be faced in the future of AI [7, 8]. Recent research on algorithmic interaction [9] have shown the important role of FATE in the experience of algorith-mic services [10]. Against the black box of algorithms, users are tasked to evaluate the vague qualities of algorithms, which are inherently heuristic and subjective because there are no specific values to define fair, transparent, or accountable [11]. Thus, in understanding such issues, scholars [8] argue that we should focus on the users' cognitive process through which we interpret our experiences and come to our own unique understandings that are related to user

Explainable AI approaches to trace human-interpretable decision processes from algorithms have been explored. Yet, little is known about algorithmic explainability from a human factors' perspective. From the perspective of user interpretability and understandability, this study examines the effect of explainability in AI on user trust and attitudes toward AI. It conceptualizes causability as an antecedent of explainability and as a key cue of an algorithm and examines them in relation to trust by testing how they affect user perceived performance of AI-driven services. The results show the dual roles of causability and explainability in terms of its underlying links to trust and subsequent user behaviors. Explanations of why certain news articles are recommended generate users trust whereas causability of to what extent they can understand the explanations affords users emotional confidence. Causability lends the justification for what and how should be explained as it determines the relative importance of the properties of explainability. The results have implications for the inclusion of causability and explanatory cues in AI systems, which help to increase trust and help users to assess the quality of explanations. Causable explainable AI will help people understand the decision-making process of AI algorithms by bringing transparency and accountability into AI systems.

We develop a cognitive model using the constructs of anthropomorphism and explainability to explain user experiences with conversational journalism (CJ) in the context of chatbot news. We examine how users perceive anthropomorphic and explanatory cues, and how these stimuli influence user perception of and attitudes toward CJ. Anthropomorphic explanations of why and how certain items are recommended afford users a sense of humanness, which then affects trust and emotional assurance. Perceived humanness triggers a two-step flow of interaction by defining the baseline to make a judgment about the qualities of CJ and by affording the capacity to interact with chatbots concerning their intention to interact with chatbots. We develop practical implications relevant to chatbots and ascertain the significance of humanness as a social cue in CJ. We offer a theoretical lens through which to characterize humanness as a key mechanism of human-artificial intelligence (AI) interaction, of which the eventual goal is humans perceive AI as human beings. Our results help to better understand human-chatbot interaction in CJ by illustrating how humans interact with chatbots and explaining why humans accept the way of CJ.

While customer satisfaction of most goods and services has been well researched, little research seems to exist on satisfaction and loyalty with respect to advanced mobile services, such as smartphones. This study applied a customer satisfaction index (CSI) model to the smart mobile sector in order to derive a smart-service CSI (SCSI). The SCSI model and its hypotheses were then tested using partial least square analysis and index calculation. The findings showed that the perceived value and customer satisfaction are key variables mediating the relationship between quality and customer loyalty. The proposed model demonstrated strong explanatory power, with satisfactory reliability and validity. The SCSI model establishes a foundation for future smart service categories on the basis of providing a powerful tool for quality assessment. The results of this study provide useful insights for the telecom industry and policymakers, for the forging of effective policies and competitive strategies.

The thesis focuses on adaptation as the key in the conversion process of visual image content to a themed space. There are many published studies dealing with storytelling, adaptation from books to movies and TV shows, or from movies to games and vice versa. On the contrary, when it comes to adaptation from visual image content to spatial content, noticeably few studies were done on the method, and fewer studies view adaptation as the prior step of storytelling. This study first defines adaptation, and then applies the methods of Gianetty and Dudley which is further incorporated into the conversion of visual image content into a themed space. It then turns the attention to the characteristics of themed spaces. A case study highlights that a themed space is a spatial representation of the story, image and action in the visual image content, and analyze the type of adaptation made. The study results draws two conclusions; adaptation must be carried out prior to the storytelling of the spatial content; and opposed to a third-person view of the visual image content, the main factor in a themed space is first-hand experience. Thus, the thesis suggests that conversion from visual image content to themed spaces are not merely imitative but is a full range of recreation of a new content. It is expected that more detailed analyses on the particulars will lead to feasible outcome on implementing various methods of adaptation and bring about effective conversions between the visual image contents and themed spaces. ■ keyword :|Visual Image Content|Theme Space|Conversion|Adaptation|Representation| *이 논문은 정부재원(교육과학기술부 일반기초연구비)으로 한국연구재단의 지원을 받아 연구되었다(

Ambidextrous information search: linking personal and impersonal search routines with individual performance

While the utilization of knowledge is likely to improve organizational performance, it is unclear what the consequences of utilizing personal and impersonal sources of information are for individuals. This study sought to increase understanding of the performance implications of using personal and impersonal information, by examining four business units of a large financial institution. Utilizing competing theoretical models, we tested whether personal and impersonal sources of information substituted for, or complemented each other. The results indicated that individuals who utilized information from personal and impersonal sources of knowledge in a complementary fashion had superior performance. Parsing impersonal knowledge sourcing, we found that the use of specific impersonal information repositories increased performance, while the use of general impersonal information decreased performance. In general, this study shed light on the origins of individual knowledge capabilities, and indicated that individuals gain advantages, by engaging in particular knowledge-sourcing routines.

A total of 72 cases about science ethics were extracted from 20 or more HOS books, journal articles, and newspaper articles. These cases were categorized into 8 areas, such as forgery, fabrication, violation of bioethics in testing, plagiarism and stealth, unfair allocation of credit, over slander, conjunction with ideologies, and social responsibility problems. The results of this study are as follows. First, research forgery, occurring in the process of the research, was the most frequent in HOS. Second, we developed eight teaching lesson plans for each area. Third, we proposed a teaching and learning model based on the developed lesson plans as well as related teaching and learning models in the fields of science ethics education, ethics education, and history education. Our model has five steps, 'investigating-suggesting casesclarifying problems-finding alternatives-summarizing'.

Employing a value-sensitive approach, we undertook theoretical and empirical analyses to explore the values that influence potential users’ adoption of cloud courseware, by integrating cognitive motivations and user values as primary determining factors. We found that users’ intentions and behaviours are largely influenced by their perceptions of what is valuable about the cloud courseware in terms of sociability, learnability, and usability. These evaluations were found to be significant antecedents of cloud-computing intentions. This study makes a contribution to theory development as our model extends existing technology acceptance models and can be used to design user interfaces and promote the acceptance of cloud computing. For practical applications, the study findings can be used by industries promoting cloud services to increase user acceptance by addressing user values and incorporating them into cloud-computing design.

In particular, p53's role in HDAC6 inhibitor-induced effects has not been fully elucidated. In this study, we show that an HDAC6-selective inhibitor, A452, increased wild-type p53 levels by destabilizing MDM2, but decreased mutant p53 by inducing MDM2 and inhibiting Hsp90-mutant p53 complex formation. Interestingly, HDAC6 levels inversely correlated with p53 acetylation at lysines 381/382 associated with p53 functional activation. A452 blocked HDAC6 nuclear localization, resulting in increased levels of acetylated p53 at Lys381/382. HDAC6 bound to the C-terminal region of p53 via its deacetylase domain. A452 disrupted the HDAC6-Hsp90 chaperone machinery via Hsp90 acetylation and degradation. Furthermore, it chemosensitized cancer cells to the Hsp90 inhibitor 17-AAG. Overall, silencing of HDAC6 showed similar effects. These findings suggest...
