An Analysis of Information Technology (IT) Post-Adoption Behavior
Get PDFThe primary focus of this research is explicating the role of emotion in IT post-adoption behavior. Studied in the context of intelligent personal assistants (IPA), a class of conversational artificial intelligence (AI), the first study integrates elements from computer science, communications, and IS disciplines. The research identifies two constructs vital for speech-based technologies, natural language understanding, and feedback, and examines their role in use decisions. This work provides guidance to practice on how best to allocate R&D investments in conversational AI. The second essay examines the IT continuance through the theoretical lens of the expectation-confirmation model (ECM), incorportating cognitive and emotional satisfaction into the ECM framework. Empirical testing of the model suggests that it offers additional clarity on IT continuance phenomena and provides a significant improvement to the explanatory power of ECM in the context of an emerging technology. The third essay is one of the earliest efforts to conceptualize and test a theoretical model that considers emotional attachment in IT continuance behavior. This essay develops a novel model to investigate this phenomenon based on emotional attachment theory, and empirically validates the proposed model in the context of conversational artificial intelligence systems. While the existing theories of IT continuance focus on purely rational, goal-oriented factors, this study incorporates non-cognitive aspects by including the emotional consequences of IT continuance and offers evidence that attachment can exist even in the absence of cognitive factors

AGRICULTURAL EXTENSION AND INFORMATION SYSTEMThe purposes of the study were to describe the selected characteristics of the farmers; to
determine the extent of farmers’ use of modern irrigation technique and to explore the
contribution among each of the selected characteristics of farmers with their use of modern
irrigation techniques. The study was undertaken purposively in Kishoreganj Upazila under
Nilphamari District. Validated and well-structured interview schedule was used to collect
data from 101 respondents during 1st July, 2021 and completed in 30 July, 2021.
Descriptive statistics, multiple regressions were used for analysis. The majority (65.34
percent) of the farmers had medium use of modern irrigation techniques compared to
having 26.23 percent high and 7.92 percent had low use of modern irrigation techniques.
Among 11 selected characteristics of the farmers three characteristics namely- education,
training received and knowledge on agricultural irrigation of the respondents had significant
positive contribution with their use of modern irrigation techniques but problem faced by the
farmers in using modern irrigation techniques of the respondents had significant negative
contribution with their use of modern irrigation techniques. The rest 7 characteristics
namely, age, family size, farm size, annual family income, farming experience, agricultural
extension media contact and attitude towards using modern irrigation techniques had no
significant contribution with their use of modern irrigation techniques. Almost half of the
farmers (48.51%) were illiterate to primary level education. Finding leads to conclude that,
if suitable steps are taken to improve education level of the farmers, an appreciable
proportion of the farmers will be encouraged to use of modern irrigation techniques.
Increase in training facilities to develop modern irrigation techniques will minimize farmer’s
problems. If the farmers gain more knowledge on modern irrigation, they will face less
problems in use of modern irrigation techniques
The Effect of Perceived Innovativeness of Student Response Systems (SRSs) on Classroom Engagement
Get PDFStudents’ engagement in classes, especially in the large classes, is a challenge. Information technology (IT) is changing the way of learning in a classroom and use of IT in the education sector has significantly improved effective teaching and the learning process. Student response systems (SRSs) are one of such technologies that can enhance students’ engagement in the classroom environment. The purpose of this study is to understand how SRSs affect students’ motivation to engage in classroom activities. We hypothesized that innovativeness of SRSs, enjoyment and attitude toward SRSs can enhance students’ engagement in classrooms. We will empirically test the hypotheses. The study will help IS researchers and instructors to understand better how students’ engagement in the classroom environment can be augmented using SRSs. The findings of this study will also help in technological solution of SRSs. \ \ Keywords \ Student response systems, theory of innovation diffusion, engagement intention, classroom environment
Risk and Liability in Autonomous Vehicle Technology
Get PDFAutonomous vehicle (AV) systems failures recently caused multiple accidents that resulted in serious personal injury and death. These include a March 2018 accident involving a Tesla vehicle in autopilot mode that crashed into a divider on a highway, killing the driver. Another incident involved a fully autonomous Volvo XC90 sport vehicle, owned by Uber, colliding with a pedestrian, on a bicycle, crossing the road in Tempe, Arizona (Vincent, 2018; Kohli & Chadh, 2019). As a result of these mishaps, potential passengers and owners are now apprehensive towards AV systems technology. This research examines AVs from two perspectives: AV passenger perceived system risk, and AV owner perceived system liability. It develops an AV risk model that explains the attitude of passengers towards AV technology and an AV liability model that explains the attitude of owners towards AV technology. The study addresses the following research questions: 1) What liability factors influence the attitude of AV owners towards AV technology? 2) What risk factors influence the attitude of passengers towards AV technology? We conducted an online survey of qualified Amazon MTurk respondents residing in the US. Findings indicate that owners are sensitive to the liability involved in acquiring AV technology. They worry about who they let use their vehicle and consider legal repercussions when determining their perceived liability in the event that something goes wrong. Passengers are sensitive to the risk involved with riding in AVs. They care about various types of risk including physical and psychological risks, when judging AV Technology.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
