Abstract

Information technology (IT) developments of large magnitude organize as collections of multiple projects into a single program, especially under dynamic conditions of market uncertainty that frequently change requirements or solutions midstream. Successful completion of an IT development program requires that the multiple teams work effectively together as well as independently in response to changes by relying on the differentiation of talent and knowledge available to the program manager. We consider and empirically support a model derived from principles in the multi-team systems (MTS) literature to determine the influence of differentiation among the IT program in the sharing of knowledge and information. The relationship from differentiation to program success is mediated by knowledge and information sharing, showing how to manage change through the dissemination of information and knowledge. Uncertainty of the market positively moderates the relation from differentiation among projects to information sharing. These findings contribute to the literature by empirically validating that MTS frameworks are exceptionally well suited for dealing with complex environments in the context of IT development.

Abstract

To reduce cyberattack risk, individuals are commonly encouraged to take security behaviors to prevent or detect IT threats. Previous research always generalized their empirical findings from specific security behaviors to all security behaviors, which is problematic because people who adopt different security behaviors may have different mechanisms and antecedents. This study uses the protection motivation theory (PMT) as a general theory and explores how the nature of security behavior (i.e., IT threatdetection behavior versus IT threat-prevention behavior) affects individuals' securityrelated outcomes, as well as what factors influence the extent of these relationships. We introduce construal level theory (CLT) to argue that IT threat detection security behaviors (versus IT threat prevention security behaviors) strengthen the effects of threat perception (versus efficacy perception) on one's protection motivation. We further propose that individuals' construal level determines the extent of these relationships. Two online experiments will be used to verify our hypotheses. [ABSTRACT FROM AUTHOR]

Abstract

One of the major challenges for Minimally Invasive Surgery (MIS) is the limited field of vision (FOV) of the endoscope. A previous study by the authors designed a MIS Panoramic Endoscope (MISPE) that gives the physician a broad field of view, but this approach is still limited, in terms of performance and quality because it encounters difficulty when there is smoke, specular reflections, or a change in viewpoint. This study proposes a novel algorithm that increases the MISPE’s performance. The method calculates the disparity for the region that is overlapped by the two cameras to allow image stitching. An improved evaluation of the homography matrix uses a frame-by-frame calculation, so the stitched videos are more stable for MIS. The experimental results show that the revised MISPE has a FOV that is 55% greater, and the system operates stably in real time. The proposed system allows a frame rate of 26.7 fps on a single CPU computer. The proposed stitching method is 1.55 times faster than the previous method. The stitched image that is obtained using the proposed method is as similar as the ground truth as the SURF-based stitching method that was used in the previous study.
