Keeping the Resident in the Loop: Adapting the Smart Home to the User

Abstract: Advancements in supporting fields have increased the likelihood that smart-home technologies will become part of our everyday environments. However, many of these technologies are brittle and do not adapt to the user's explicit or implicit wishes. Here, we introduce CASAS, an adaptive smart-home system that utilizes machine learning techniques to discover patterns in resident's daily activities and to generate automation polices that mimic these patterns. Our approach does not make any assumptions about the activity structure or other underlying model parameters but leaves it completely to our algorithms to discover the smart-home resident's patterns. Another important aspect of CASAS is that it can adapt to changes in the discovered patterns based on the resident implicit and explicit feedback and can automatically update its model to reflect the changes. In this paper, we provide a description of the CASAS technologies and the results of experiments performed on both synthetic and real-world data.

Did Social Media Really Matter? College Students' Use of Online Media and Political Decision Making in the 2008 Election

Abstract: This study examined college students' use of online media for political purposes in the 2008 election. Social media attention, online expression, and traditional Internet attention were assessed in relation to political self-efficacy and situational political involvement. Data from a Web survey of college students showed significant positive relationships between attention to traditional Internet sources and political self-efficacy and situational political involvement. Attention to social media was not significantly related to political self-efficacy or involvement. Online expression was significantly related to situational political involvement but not political self-efficacy. Implications are discussed for political use of online media for young adults.

Decoding the massive genome of loblolly pine using haploid DNA and novel assembly strategies

Abstract: The size and complexity of conifer genomes has, until now, prevented full genome sequencing and assembly. The large research community and economic importance of loblolly pine, Pinus taeda L., made it an early candidate for reference sequence determination. We develop a novel strategy to sequence the genome of loblolly pine that combines unique aspects of pine reproductive biology and genome assembly methodology. We use a whole genome shotgun approach relying primarily on next generation sequence generated from a single haploid seed megagametophyte from a loblolly pine tree, 20-1010, that has been used in industrial forest tree breeding. The resulting sequence and assembly was used to generate a draft genome spanning 23.2 Gbp and containing 20.1 Gbp with an N50 scaffold size of 66.9 kbp, making it a significant improvement over available conifer genomes. The long scaffold lengths allow the annotation of 50,172 gene models with intron lengths averaging over 2.7 kbp and sometimes exceeding 100 kbp in length. Analysis of orthologous gene sets identifies gene families that may be unique to conifers. We further characterize and expand the existing repeat library based on the de novo analysis of the repetitive content, estimated to encompass 82% of the genome. In addition to its value as a resource for researchers and breeders, the loblolly pine genome sequence and assembly reported here demonstrates a novel approach to sequencing the large and complex genomes of this important group of plants that can now be widely applied.

Thermosensitive Gold Nanoparticles

Abstract: Thermosensitive gold nanoparticles were fabricated by conjugating Au with a thiol-terminated poly(N-isopropylacrylamide) or PPA; this polymer stabilizer exhibits a temperature transition while undergoing a hydrophilic to hydrophobic transformation. The introduction of PPA onto gold nanoparticles has sensitized Au nanoparticles with unique temperature dependence. At low temperature (25 °C), the solutions containing PPA-functionalized gold nanoparticles are transparent, whereas higher temperatures (30 °C) lead to opaque suspensions. The thermosensitive property of PPA-functionalized Au nanoparticles is reversible, and the clear−opaque suspensions can be repeated many times.

Employees' Use of Work-Family Policies and the Workplace Social Context

Abstract: This article analyzes the effects of workplace social context on managers’ and professionals’ use of work-family policies in a financial services corporation. These official policies are ambiguous and contested and, as institutional theory implies, may fail to become fully implemented. We use a multilevel model to determine the individual-level and work group–level factors that affect respondents’ policy use. In addition to individual-level factors, the social context of the work group affects employees’ decisions to use work-family policies. We find support for our hypotheses stressing the social resource of power and protection: employees are more likely to use these policies if they work with powerful supervisors and colleagues, who can buffer them from perceived negative effects on their careers.
