Cognitive Stopping Rules in a New Online Reality

This research is a conceptual replication of a study by Browne, Pitts, and Wetherbe (2007) that explores information stopping rules in an online search context. Information stopping rules consider the cognitive reasons decision makers determine when enough information is collected to make a decision. Previous research outlines five stopping rules decision makers use and applies them in different decision context. The original research considers three information search tasks (search for a television, map, and job) and hypothesizes the relationship between structure of the task and the stopping rule employed. This research replicates that study in a new information environment with new search methodologies and technology. We find that structured tasks use similar stopping rules to the original study; however further analysis shows distinct differences in the nature of the two tasks presented. Poorly structured tasks potentially involve the use of different stopping rules than previously determined. The updated findings suggest information systems used for poorly structured search tasks might also benefit from highlighting the uniqueness of information in order to encourage a user to continue searching for information

False Rumor (Fake) and Truth News Spread During A Social Crisis

During a social crisis, the truthfulness of information becomes very important, particularly in determining if the information will spark extreme social engagement. We test a research model to examine major determinants of message spread during the 2016 Charlotte, North Carolina protests which occurred after false online rumors spread related to the shooting of Keith Lamont Scott. We hypothesize relationships between message spread (retweets) and extremity, negative emotions (sadness and fear), and social ties (reciprocal reply and location proximity), and Twitter experience. Using Poisson regression, we evaluate and compare two separate models (rumor and truth). Results of the analysis indicate that rumors and truths spread differently. More extreme messages spread less if they are truths, and fear does not relate to the spread of rumors. The results of the study provide theoretical and practical insights into the current research in the areas of information diffusion and social engagement

The Truth About Numbers: Subjectivity in the CRISP-DM Process

Analytics is undoubtedly changing the efficiency and decision making of businesses. Because analytics is inherently numeric, there is a false sense of security in their certainty; however, those that do the work can quickly identify where decisions could be made differently in the modeling process. This big idea presentation considers research on subjectivity in the CRISP-DM process

Privacy Education Effectiveness: Does It Matter?

Mobile devices are a constantly used item in a college student’s life. Students depend on them for entertainment, academics, and socializing with their friends. While they continually use them, they perhaps do not understand the impact of their use on their privacy or that the devices can be used to track them and collect their personal information. This study utilizes the Antecedent, Privacy Concern, Outcome (APCO) model, combined with the Fogg Behavior Model (FBM) to determine (1) the factors that comprise privacy concerns on a mobile device; (2) whether individuals use privacy-protective behaviors, and (3) whether education on privacy issues regarding mobile devices will increase their use of privacy-enhancing technology (PET). A longitudinal study was conducted to test whether privacy protection education increases the use of PET. While students express concern for their privacy when using mobile devices and express an intent to use additional PET, their behavior using mobile device protections does not change, even after an educational intervention. Perceived privacy control does not change their privacy concern and habit and trust outweigh the impact of privacy concern. Theoretical and practical implications are provided

Concern for Privacy of Self and Others: Sharing Behavior, and Engagement

Privacy concern continues to grow as online presences become more prevalent through social network sites (SNSs). Significant research has studied the privacy concern construct as it pertains to privacy for information about self, however little research considers a privacy concern for information about others. We hypothesize relationships between both privacy concern for self and others and three different sharing behaviors, self-sharing, non-personal sharing, and others-sharing. We further hypothesize relationships between these sharing behaviors and engagement with the SNS. Building on previous literature, we contribute by expanding unique privacy concerns and relating these to separate sharing behaviors. Further, we believe this research in progress can help future practical understandings of privacy concerns as individuals and laws attempt to improve regulations. As a research in progress, we briefly outline our intentions on data collection through a survey method and potential impact of the results

Understanding the Nature of Online News Addiction

Being aware of the happenings in a community has always been of interest to humans, but the current state of news availability is unprecedented. This convenience is driving behavioral changes that manifest in online news addiction. In this research, we seek to understand antecedents to online news addiction as a need to be socially connected. We posit that an individual’s social identity creates envy, fear of missing out, and anxiety. These factors lead to frequent news checking to the point of addiction. Through this research we expect to provide guidance on the role of social identity in technology addictions, as well as new offerings that can lead to online news addiction. In the current environment of misinformation, this research will be informative for reducing online news addiction

Double conditional human embryonic kidney cell line based on FLP and ΦC31 mediated transgene integration

<p>Abstract</p> <p>Background</p> <p>FLP recombinase mediated integration into a pre-integrated FRT site is routinely used to generate highly reproducible stable transgenic cell lines. In this study, we broaden the system of site specific integration by introducing ΦC31 integrase mediated integration into attP sites.</p> <p>Results</p> <p>We generated a HEK293 host cell line with a single copy FRT as well as an attP site allowing site specific integration of two distinct transgenes. To achieve conditional control, we used the tetracycline and Shld1 inducible systems. By introducing fluorescent reporters we show that integration and induction of two transgenes are completely independent. We applied this new technique to investigate the effect of HNF4α on proliferation of HEK293 cells by introducing HNF4α into each integration site. We obtained in two independent cell lines highly reproducible results that prove the usefulness of this novel HEK-attP/FRT cell line.</p> <p>Conclusions</p> <p>In this study we have established and applied a HEK-attP/FRT cell line that allows site specific integration of two conditional transgenes using the FLP recombinase as well as the ΦC31 integrase.</p
