Adapting robot behavior to user's capabilities: a dance instruction study.

The ALIZ-E1 projects goal is to design a robot companion able to maintain affective interactions with young users over a period of time. One of these interactions consists in teaching a dance to hospitalized children according to their capabilities. We propose a methodology for adapting both, the movements used in the dance based on the users cognitive and physical capabilities through a set of metrics, and the robots interaction based on the users personality traits

Observation of asymmetric spectrum broadening induced by silver nanoparticles in a heavy-metal oxide glass

We demonstrate experimentally and support by a theoretical analysis an effect of asymmetric spectrum broadening, which results from doping of silver nanoparticles into a heavy-glass matrix, 90(0.5WO3-0.3SbPO4-0.2PbO)-10AgCl. The strong dispersion of the effective nonlinear coefficient of the composite significantly influences the spectral broadening via the self-phase modulation, and leads to a blue upshift of the spectrum. Further extension of the spectrum towards shorter wavelengths is suppressed by a growing loss caused by the plasmon resonance in the silver particles. The red-edge spectral broadening is dominated by the stimulated Raman Scattering.Comment: Accepted for publishing epl13477; EPL Journal 201

A Technology Pathway for Airbreathing, Combined-Cycle, Horizontal Space Launch Through SR-71 Based Trajectory Modeling

Access to space is in the early stages of commercialization. Private enterprises, mainly under direct or indirect subsidy by the government, have been making headway into the LEO launch systems infrastructure, of small-weight-class payloads of approximately 1000 lbs. These moderate gains have emboldened the launch industry and they are poised to move into the middle-weight class (roughly 5000 lbs). These commercially successful systems are based on relatively straightforward LOX-RP, two-stage, bi-propellant rocket technology developed by the government 40 years ago, accompanied by many technology improvements. In this paper we examine a known generic LOX-RP system with the focus on the booster stage (1st stage). The booster stage is then compared to modeled Rocket-Based and Turbine-Based Combined Cycle booster stages. The air-breathing propulsion stages are based on/or extrapolated from known performance parameters of ground tested RBCC (the Marquardt Ejector Ramjet) and TBCC (the SR-71/J-58 engine) data. Validated engine models using GECAT and SCCREAM are coupled with trajectory optimization and analysis in POST-II to explore viable launch scenarios using hypothetical aerospaceplane platform obeying the aerodynamic model of the SR-71. Finally, and assessment is made of the requisite research technology advances necessary for successful commercial and government adoption of combined-cycle engine systems for space access

Does Attending a Regional Medical Campus Influence the Training Outcomes of Family Medicine Residents?

Introduction: Indiana University School of Medicine (IUSM) is the largest medical school in the nation, with its main campus located in Indianapolis and eight regional medical campuses (RMC) distributed across the state. In this study, we compared the survey responses of family medicine residents who had attended medical school at the main campus in Indianapolis versus an RMC to see if there were any noticeable differences in their residency training outcomes. Methods: From 2012 to 2017, in the spring of each year, a cross-sectional survey was administered to all final-year family medicine residents graduating from the eleven family medicine residency programs in Indiana. A total of 519 out of 520 residents completed the survey. Of whom, 132 respondents indicated they had graduated from IUSM; 45 reported they had attended the Indianapolis campus and 87 had attended one of the RMCs in the state. Our dataset for this study was comprised of these 132 respondents. Chi-square test or Fisher’s exact test were used to compare responses between groups. P-values ≤ 0.05 were considered statistically significant. Results: In the ACGME competency areas, the residents who attended an RMC versus the Indianapolis campus were significantly more likely to report being fully competent in Medical Knowledge (90% vs. 76%, p = 0.032) and Systems-Based Practice (83% vs. 64%, p = 0.019). Additionally, the residents who attended an RMC compared to their Indianapolis counterparts reported significantly higher rates of being trained to serve rural populations (73% vs. 52%, p = 0.017) as well as being fully competent to serve rural populations (69% vs. 42%, p = 0.003). However, the residents who attended an RMC were no more likely to establish a practice in a rural area than were the residents who attended Indianapolis (18% vs. 17%, p = 0.845). Conclusions: Based on these self-reported data, the family medicine residents who attended an RMC may perceive themselves to be better-prepared in a few core competency areas, as well as in serving rural populations, compared to those who attended the Indianapolis campus. These findings suggest that IUSM’s complex statewide system of medical education may offer some unique advantages in preparing students for residency, especially in family medicine

Tracking Medical Students and Graduates from Hometown to Practice using Geographic Information Systems, 2011-2017

Background: Indiana University School of Medicine (IUSM) through its statewide system provides medical education and clinical experiences across Indiana for more than 1,450 medical students in nine regions, including Indianapolis and eight regional medical campuses (RMCs). The majority of medical students begin their education distributed among the RMCs, and some students continue clinical experiences at the RMCs for their third and fourth years. Methods: We used a Geographic Information System (GIS) to visualize and document the contribution of our RMCs in Indiana to the physician workforce pipeline. Using data from the 2011-2017 graduating classes, we created a geospatial database that linked key information from student records and public domain sources (e.g., hometown, campus assignment, PGY1 specialty, and practice) with their corresponding locational information. ArcGIS 10.5 GIS software was used to produce a series of maps to visualize patterns in student outcomes among the RMCs over time. Results: By using GIS to track medical trainees from hometown to practice, we can provide accurate visualization of extensive geographic data. The maps revealed similarities and differences among the RMCs not fully appreciated until visually mapped, including the specialty choice of students from different campuses and the proportion of graduates practicing in medically underserved areas of the state. Conclusions: GIS maps and their analyses can identify strengths and distinctions among the RMCs while providing accurate descriptions of the role of geography in the professional development journey of the physician workforce. This ongoing project is a major step toward integrating GIS as a familiar tool in academic administration and health workforce research to assist future decision-making by the school leadership

THE EFFECT OF ORGANIZATIONAL CULTURE TOWARDS ENTREPRENEURIAL ORIENTATION IN SRI LANKAN HOSPITALITY OPERATIONS

The article examines the relationship between the organizational culture and the entrepreneurial orientation in the Sri Lankan hospitality sector. The data for the study was collected from 215 managers occupying senior positions star class hotel sector. The analysis was performed based on CFA SEM techniques using AMOS 21 software to identify the relationship. The quantitative data analysis revealed there is a significant relationship between organizational culture and entrepreneurial orientation. In the research entrepreneurial orientation was reflected with three dimensions proactiveness, risk taking and innovativeness. The organizational culture was reflected with four dimensions organizational climate, flexibility or the support to change, team work and employee empowerment. This study develops a better understanding of elements of organizational culture and entrepreneurial orientation.  Article visualizations
