TL;DR: An early intervention solution for collegiate faculty called Course Signals, developed to allow instructors the opportunity to employ the power of learner analytics to provide real-time feedback to a student, is discussed.
Abstract: In this paper, an early intervention solution for collegiate faculty called Course Signals is discussed. Course Signals was developed to allow instructors the opportunity to employ the power of learner analytics to provide real-time feedback to a student. Course Signals relies not only on grades to predict students' performance, but also demographic characteristics, past academic history, and students' effort as measured by interaction with Blackboard Vista, Purdue's learning management system. The outcome is delivered to the students via a personalized email from the faculty member to each student, as well as a specific color on a stoplight -- traffic signal -- to indicate how each student is doing. The system itself is explained in detail, along with retention and performance outcomes realized since its implementation. In addition, faculty and student perceptions will be shared.

TL;DR: In this article, the authors used a methodology robust to recent criticisms of standard long-horizon event study tests to show that bidders in mergers underperform while bidder in tender o¼ers overperform in the three years after the acquisition.

TL;DR: In this article, the authors extended Mehrabian and Russell's stimulus-organism-response framework by incorporating restaurant-specific stimuli and including restaurant specific measures of emotion using structural equation modeling, which showed that atmospherics and service function as stimuli that enhance positive emotions while product attributes, such as food quality, act to relieve negative emotional responses.

TL;DR: This paper reports that adding formaldehyde during biomass pretreatment produces a soluble lignin fraction that can be converted to guaiacyl and syringyl monomers at near theoretical yields during subsequent hydrogenolysis, three to seven times those obtained without formaldehyde.
Abstract: Practical, high-yield lignin depolymerization methods could greatly increase biorefinery productivity and profitability. However, development of these methods is limited by the presence of interunit carbon-carbon bonds within native lignin, and further by formation of such linkages during lignin extraction. We report that adding formaldehyde during biomass pretreatment produces a soluble lignin fraction that can be converted to guaiacyl and syringyl monomers at near theoretical yields during subsequent hydrogenolysis (47 mole % of Klason lignin for beech and 78 mole % for a high-syringyl transgenic poplar). These yields were three to seven times those obtained without formaldehyde, which prevented lignin condensation by forming 1,3-dioxane structures with lignin side-chain hydroxyl groups. By depolymerizing cellulose, hemicelluloses, and lignin separately, monomer yields were between 76 and 90 mole % for these three major biomass fractions.
