User-activity aware strategies for mobile information access

Information access suffers tremendously in wireless networks because of the low correlation between content transferred across low-bandwidth wireless links and actual data used to serve user requests. As a result, conventional content access mechanisms face such problems as unnecessary bandwidth consumption and large response times, and users experience significant performance degradation. In this dissertation, we analyze the cause of those problems and find that the major reason for inefficient information access in wireless networks is the absence of any user-activity awareness in current mechanisms. To solve these problems, we propose three user-activity aware strategies for mobile information access. Through simulations and implementations, we show that our strategies can outperform conventional information access schemes in terms of bandwidth consumption and user-perceived response times.Ph.D.Committee Chair: Raghupathy Sivakumar; Committee Member: Chuanyi Ji; Committee Member: George Riley; Committee Member: Magnus Egerstedt; Committee Member: Umakishore Ramachandra

How Does Corporate Social Responsibility Promote Innovation? The Sequential Mediating Mechanism of Employees’ Meaningfulness of Work and Intrinsic Motivation

Based on group creativity framework, our research investigates how corporate social responsibility (CSR) promotes innovation of firms by revealing sequential mediating mechanisms of employee’s meaningfulness of work and intrinsic motivation. By applying a multi-level approach, this study examines the internal processes of micro-level variables between two macro-level variables (i.e., CSR and innovation). Utilizing a 3-wave longitudinal data from 4,178 organizational members in 502 branches as well as objective CSR records from one of the largest Korean commercial banks, we found that employee’s meaningfulness of work and intrinsic motivation sequentially mediate the CSR-innovation link. The results suggest that CSR functions as a powerful driver of innovation through enhancing employees’ perceptions and attitudes toward their job

Eastern Staining: A Simple Recombinant Protein Detection Technology Using a Small Peptide Tag and Its Counter Partner Which is a Fluorescent Compound

Small peptide tags such as c-myc, HA, or FLAG tag have facilitated efficient Westernblotting of proteins of interest especially when specific antibodies for the proteins are not available. However, the conventional Western-blotting requires the multi-steps process taking at least several hours up to two days. With examples of various applications, here we show a convenient and time-saving method for protein detection which employs a fluorescent chemical BDED and its binding peptide RC-tag. And we propose “Estern staining”, as a standard term for protein detection method using fluorescent chemicals and their binding small peptide tags. Eastern staining may substitutes for the time-consuming “immuno-staining” in many versatile applications.22Yothe
