Teaching Data Analytics Using Real Estate Data

Data analytics, especially statistics, can be intimidating due to its jargon, symbols, and obscure terminologies. This teaching case demonstrates how to make these abstract and technical concepts much more concrete and approachable by having students participate in the process of putting together a real estate dataset. Real estate data collected from real estate websites are excellent for teaching data analytics, particularly statistics, because they are easy to understand, produce strong and predictable results, and demonstrate core machine learning concepts and tangible applications. This case provides example data collection survey, in-class exercises, and templates for calculating statistics from the real estate dataset

Genetic Basis of Behavioral Security

Behavioral genetics offers numerous opportunities to bridge gaps in biological research of IS and to shed light on the nature versus nurture debate. This study seeks to explain persistent weaknesses in behavioral security from a genetic perspective. A synthesis of current literatures on cognitive neuroscience, decision making, and fraud victimization suggests a genetic basis for user susceptibility to security risks such as phishing scams. Using the classic twin design, this study reports estimated heritability of behavioral security to be at least 29.15% by comparing concordance between 144 pairs of monozygotic (MZ) twins and that between 52 pairs of same-sex dyzygotic (DZ) twins. Zygosity of the twin pairs serves as the primary independent variable in the behavioral genetics analysis, while performance on a behavioral security test serves as the dependent measure. Implications of the study results are discussed with respect to IS research as well as managerial practices

Alexithymia and posttraumatic stress disorder following epileptic seizure

This study investigated (1) the incidence of posttraumatic stress disorder following epileptic seizure (post-epileptic seizure PTSD) and psychiatric co-morbidity and (2) the extent to which alexithymia traits related to the severity of the preceding outcomes. Seventy-one people with epilepsy participated in the study and completed the Posttraumatic Stress Diagnostic Scale, Hospital Anxiety and Depression Scale (HADS), and Toronto Alexithymia Scale. The control group comprised 71 people without epilepsy who completed the HADS. Fifty-one percent met the diagnostic criteria for full-PTSD; 30 % for partial-PTSD and 19 % for no-PTSD. The epilepsy group reported significantly more anxiety and depression than the control with demographic variables controlled for. Difficulty identifying feelings predicted post-epileptic seizure PTSD, anxiety and depression. It was positively correlated with post-epileptic seizure PTSD and depression, while it was negatively correlated with anxiety. People can develop PTSD and psychiatric co-morbid symptoms following epileptic seizures. The severity of these symptoms was related to difficulty in identifying internal feelings and emotions. © 2012 Springer Science+Business Media New York

Robotic motion learning framework to promote social engagement

Abstract Imitation is a powerful component of communication between people, and it poses an important implication in improving the quality of interaction in the field of human–robot interaction (HRI). This paper discusses a novel framework designed to improve human–robot interaction through robotic imitation of a participant’s gestures. In our experiment, a humanoid robotic agent socializes with and plays games with a participant. For the experimental group, the robot additionally imitates one of the participant’s novel gestures during a play session. We hypothesize that the robot’s use of imitation will increase the participant’s openness towards engaging with the robot. Experimental results from a user study of 12 subjects show that post-imitation, experimental subjects displayed a more positive emotional state, had higher instances of mood contagion towards the robot, and interpreted the robot to have a higher level of autonomy than their control group counterparts did. These results point to an increased participant interest in engagement fueled by personalized imitation during interaction

The association between body image and psychological well-being in adult women

The findings of this thesis highlighted the role of functional aspects of body image (i.e., self-rated health/ fitness) in positively shaping the well-being of young and middle-aged women. A novel finding was the strong association found between women’s body image and how well they believed they managed their life situations
