Lotus Effect in Engineered Zirconia

Abstract: Patterned micro- and nanostructured surfaces have received increasing attention because of their ability to tune the hydrophobicity and hydrophilicity of their surfaces. However, the mechanical properties of these studied surfaces are not sufficiently robust for load-bearing applications. Here we report transparent nanocrystalline ZrO2 films possessing combined properties of hardness and complete wetting behavior, which are expected to benefit tribology, wear reduction, and biomedical applications where ultrahydrophilic surfaces are required. This ultrahydrophilic behavior may be explained by the Wenzel model.

Exploring the Effect of Distance: An Experimental Investigation of Virtual Collaboration, Social Loafing, and Group Decisions

Abstract: Contemporary businesses are rapidly embracing virtual collaboration as a flexible, cheaper, and more efficient method for conducting group work. Past research has shown, however, that virtual groups operate quite differently than face‐to‐face groups. In this study, Social Impact Theory provides a framework to investigate whether virtual collaboration heightens social loafing—the tendency for individuals to contribute less than full effort to a group. The theory predicts that member distance, inherent in virtual collaboration, increases the propensity of group members to loaf, and decreases group performance. Two hundred seventy‐nine participants assigned to face‐to‐face or virtual groups completed a business resources allocation task. Results suggest that virtual collaboration negatively affects group performance and that social loafing behavior may partially explain this result. The findings imply that organizations should carefully consider whether virtual collaboration can be seamlessly substituted for...

ICedge : When Edge Computing Meets Information-Centric Networking

Abstract: In today’s era of explosion of Internet of Things (IoT) and end-user devices and their data volume emanating at the network’s edge, the network should be more in-tune with meeting the needs of these demanding edge computing applications. To this end, we design and prototype Information-Centric edge ( ICedge ), a general-purpose networking framework that streamlines service invocation and improves the reuse of redundant computation at the edge. ICedge runs on top of named-data networking, a realization of the information-centric networking vision, and handles the “low-level” network communication on behalf of applications. ICedge features a fully distributed design that: 1) enables users to get seamlessly on-boarded onto an edge network; 2) delivers application invoked tasks to edge nodes for execution in a timely manner; and 3) offers naming abstractions and network-based mechanisms to enable (partial or full) reuse of the results of already executed tasks among users, which we call “compute reuse,” resulting in lower task completion times and efficient use of edge computing resources. Our simulation and testbed deployment results demonstrate that ICedge can achieve up to $50\times $ lower task completion times leveraging its network-based compute reuse mechanism compared to cases, where reuse is not available.

Involved Parents' Perceptions of Their Experiences in School-Based Team Meetings

Abstract: We explored parents' perceptions of their positive and negative experiences in school-based team meetings as a first step toward identifying the characteristics that may promote meaningful parent participation. Parent members of a Midwestern suburban school district's special education advisory group provided open-ended descriptions of their positive and negative experiences in school-based team meetings. Their responses were coded, summarized, and reported back to participants who then evaluated the summary for accuracy and completeness. The results yielded 17 specific items that were grouped into five categories: meeting context and organization, relationships, communication, problem solving, and parent emotions. The implications of parents' responses for practice as well as for future research are discussed.

Seasonal Variations in Fuel and Fuel Consumption by Fires in a Bluestem Prairie

Abstract: Plots in an ungrazed, re—established grassland near Omaha, Nebraska, USA, dominated by little bluestem (Andropogon scoparius), were burned at 3—wk intervals from March through November 1976. The amount of vegetative biomass consumed during burning, a measure of flammability, was high throughout the study period, varying from >99% in April to 84% in mid—June. Areas burned in March were able to carry a second fire in October of the same year. High flammability throughout the growing season, in conjunction with current fire and climatic records, suggests that widespread, late—summer fires were probably common in presettlement, ungrazed, bluestem prairies.
