Animated Video-Making: A Collaborative Approach to Researching Inclusion and Support for Immigrant Seniors

This visual essay describes how we as artist-scholars used arts-based research (ABR) to examine seniors’ experience during the COVID-19 pandemic, as well as to consider ways of fostering social inclusion and integration through an ABR approach to public engagement with research. Central to this inquiry is how ABR, as visual storytelling that combines a narrative with digital content, allows us to capture these seniors’ complex lived experiences while serving as public-friendly research output accessible to a wide range of community members

Is deck C an advantageous deck in the Iowa Gambling Task?

<p>Abstract</p> <p>Background</p> <p>Dunn <it>et al.</it> performed a critical review identifying some problems in the Somatic Marker Hypothesis (SMH). Most of the arguments presented by Dunn focused on the insufficiencies for replication of skin conductance responses and somatic brain loops, but the study did not carefully reassess the core-task of SMH. In a related study, Lin and Chiu et al. identified a serious problem, namely the "prominent deck B phenomenon" in the original IGT. Building on this observation, Lin and Chiu also posited that deck C rather than deck A was preferred by normal decision makers due to good gain-loss frequency rather than good final-outcome. To verify this hypothesis, a modified IGT was designed that possessed high contrast of gain-loss value in each trial, with the aim of achieving a balance between decks A and C in terms of gain-loss frequency. Based on the basic assumption of IGT, participants should prefer deck C to deck A based on consideration of final-outcome. In contrast, based on the prediction of gain-loss frequency, participants should have roughly equal preferences for decks A and C.</p> <p>Methods</p> <p>This investigation recruited 48 college students (24 males and 24 females) as participants. Two-stage IGT with high-contrast gain-loss value was launched to examine the deck C argument. Each participant completed the modified IGT twice and immediately afterwards was administered a questionnaire to assess their consciousness and final preferences following the game.</p> <p>Results</p> <p>The experimental results supported the predictions regarding gain-loss frequency participants choose the deck C with nearly identical frequency to deck A, despite deck C having a better final outcome than deck A. The "sunken deck C" phenomenon is clearly identified in this version of IGT which achieves a balance in gain-loss frequency. Moreover, the "sunken deck C" phenomenon not only appears during the first stage, but also during the second stage of IGT. In addition, questionnaires indicated that normal decision makers disliked deck C at the consciousness (explicit) levels.</p> <p>Conclusion</p> <p>In the modified version of IGT, deck C was no longer preferred by normal decision makers, despite having a better long-term outcome than deck A. This study identified two problems in the original IGT. First, the gain-loss frequency between decks A and C is pseudo-balanced. Second, the covered phenomenon leads to most IGT related studies misinterpreting the effect of gain-loss frequency in situations involving long-term outcomes, and even leads to overstatement of the foresight of normal decision makers.</p

Glycocalyx production and adherence of Staphylococcus to biomaterials.

&#60;P&#62;Glycocalyx is suggested to play an important role in the pathogenesis of biomaterial-centered infection. Using an accurate and sensitive method to quantify glycocalyx and bacterial adherence, we have demonstrated that the producer of the most glycocalyx also exhibited the highest adherence index, whereas low producers exhibited the least (p less than 0.01). Additionally, at various concentrations the high producer had the greater tendency to adhere and grow on stainless steel wires and tubes (p less than 0.001). The adherence index, referred as the ratio of tritiated thymidine uptake on wires to colony forming units (CFU), was also the highest in high producers. The adherence index increased as the glycocalyx index increased. It was suggested that glycocalyx production enhanced the adherence of Staphylococcus epidermidis to biomaterials and caused persistent and intractable infections. In short, the glycocalyx index and the adherence index can be reliable indices of biomaterial-centered infection.</p

An empirical study of the impact of internet financial reporting on stock prices

This study examines the economic consequences of internet financial reporting (IFR) in Taiwan. The results show that the stock prices of IFR firms change more quickly than those of the non-FR firms using Akaike’s (1969) Final Prediction Error (FPE) methodology. Second, the results from the event study methodology show that the cumulative abnormal returns of the firms with IFR are significantly higher than those of the firms without IFR. Lastly, the results indicate that firms with a higher degree of information transparency yield a higher abnormal return on theirstock prices

UMIRobot: An Open-{Software, Hardware} Low-Cost Robotic Manipulator for Education

Robot teleoperation has been studied for the past 70 years and is relevant in many contexts, such as in the handling of hazardous materials and telesurgery. The COVID19 pandemic has rekindled interest in this topic, but the existing robotic education kits fall short of being suitable for teleoperated robotic manipulator learning. In addition, the global restrictions of motion motivated large investments in online/hybrid education. In this work, a newly developed robotics education kit and its ecosystem are presented which is used as the backbone of an online/hybrid course in teleoperated robots. The students are divided into teams. Each team designs, fabricates (3D printing and assembling), and implements a control strategy for a master device and gripper. Coupling those with the UMIRobot, provided as a kit, the students compete in a teleoperation challenge. The kit is low cost (< 100USD), which allows higher-learning institutions to provide one kit per student and they can learn in a risk-free environment. As of now, 73 such kits have been assembled and sent to course participants in eight countries. As major success stories, we show an example of gripper and master designed for the proposed course. In addition, we show a teleoperated task between Japan and Bangladesh executed by course participants.
