Automated lecture video recording, post-processing, and viewing system that utilizes multimodal inputs to provide a dynamic student experience

Thesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2013.Cataloged from PDF version of thesis.Includes bibliographical references (page 59).This thesis describes the design, implementation, and evaluation of EduCase: an inexpensive automated lecture video recording, post-processing, and viewing system. The EduCase recording system consists of three devices, one per lecture hall board. Each recording device records color, depth, skeletal, and audio inputs. The Post-Processor automatically processes the recordings to produce an output file usable by the Viewer, which provides a more dynamic student experience than traditional video playback systems. In particular, it allows students to flip back to view a previous board while the lecture continues to play in the background. It also allows students to toggle the professor's visibility in and out to see the board they might be blocking. The system was successfully evaluated in blackboard-heavy lectures at MIT and Harvard. We hope that EduCase will be the quickest, most inexpensive, and student-friendly lecture capture system, and contribute to our overarching goal of education for all.by Sara T. Itani.M. Eng

Social media and customer relationship management technologies: Influencing buyer-seller information exchanges

Highlights Social media and CRM technology aid salespeople in market sensing and customer-linking activities. Social media utilization enhance the competitive information collection abilities of the seller. CRM techpositively affects seller product information communication, which enablesbuyer information sharing intentions. Sellers capture value from buyers by CRM utilization. Seller experience has significant moderating and explanatory power regarding the use of sales technology. Abstract Due to the increasing array of sales technology, salespeople must understand how each application assists them. This study examines how business-to-business salespeople use different forms of sales technology to meet their boundary-spanning roles. Our research draws from social exchange theory and task-technology fit theory to test a model that examines how salespeople use CRM and social media technologies differentially to support competitive information collection, product information communication, and buyer information sharing. Dyadic data from industrial buyers and sellers is used to analyze the technology-behavior relationships. Our study\u27s results reveal social media use and CRM technology both positively influence buyer-seller information exchanges; however, each technology takes a distinct route to enable the information exchange between the buyer and the seller. The results also suggest that managers need to champion the use of both technology applications to their salesforce

Salesperson ambidexterity and customer satisfaction: examining the role of customer demandingness, adaptive selling, and role conflict

This research investigates the effects of sales-service ambidexterity on salesperson role perceptions, behaviors, and customer satisfaction. Using a business-to-business, salesperson-customer sample, we build and test a model which highlights both the positive and negative consequences of this simultaneous goal pursuit. Specifically, while sales-service ambidexterity positively impacts adaptive selling behaviors, it also increases perceptions of role conflict among salespeople. Customer demandingness moderates these relationships. Taken together, the results provide insights for firms on how to manage their sales force to optimize both sales and service outcomes based on characteristics of their salespeople and customers

Inside sales social media use and its strategic implications for salesperson-customer digital engagement and performance

Highlights Inside salespeople rely on four main strategies when it comes to using social media in their roles to engage with customers. Inside sales strategic social media use leads to higher levels of customer digital engagement and, ultimately, performance. Firm digital technology resources may shape the effects of inside sales strategic social media use. Abstract The nature of inside sales has shifted, increasing in autonomy, importance, and scope. Moreover, buyers are changing their preferences from face-to-face interactions to virtual-based relationships, leading to a future full of opportunities for inside salespeople using social media. The practitioner literature suggests that inside sales represent the sales business model of the digital era and a distinct strategic selling approach. While there has been a recent surge in theoretical research on inside sales, extant research fails to explore how and why inside salespeople uses social media as a critical tool. Research on social media use in sales has neglected to consider the growing role of inside sales, where sellers lack the opportunity to meet with customers face-to-face and must routinely rely on remote communication to interact with customers. As such, we use a grounded theory approach to investigate the “lived experiences” of inside salespeople at the intersection with social media in sales. Emergent from our findings is a framework depicting: inside sales strategic social media use → inside salesperson-customer digital engagement → inside sales performance. We also find that firm digital technology resources serve as enablement factors that shape the effects of the social media strategies that inside salespeople use

Countrywide spread of OXA-48 carbapenemase in Lebanon: Surveillance and genetic characterization of carbapenem-non-susceptible Enterobacteriaceae in 10 hospitals over a one-year period

© 2014 The Authors. Objectives: To detect, characterize, and assess the genetic clonality of carbapenem-non-susceptible Enterobacteriaceae in 10 Lebanese hospitals in 2012. Methods: Selected Enterobacteriaceae isolates with reduced susceptibility to carbapenems were subject to phenotypic study including antibiotic susceptibility, cloxacillin effect, modified Hodge test, and activity of efflux pump inhibitor. Carbapenemase genes were detected using PCR; clonal relatedness was studied by pulsed field gel electrophoresis. Results: Out of 8717 Enterobacteriaceae isolated in 2012, 102 (1.2%) showed reduced susceptibility to carbapenems. Thirty-one (70%) of the 44 studied clinical isolates harbored blaOXA-48, including 15 Klebsiella pneumoniae, eight Escherichia coli, four Serratia marcescens, three Enterobacter cloacae, and one Morganella morganii. The majority of OXA-48 producers co-secreted an extended-spectrum beta-lactamase, while one had an acquired AmpC of the ACC type. In the non-OXA-48 producers, carbapenem resistance was attributed to the production of acquired AmpC cephalosporinases of MOX or CIT type, outer membrane impermeability, and/or efflux pump overproduction. DNA fingerprints revealed that OXA-48 producers were different, except for clonal relatedness among four K. pneumoniae, two E. coli, two E. cloacae, and three S. marcescens. Conclusions: Nosocomial carbapenem-non-susceptible Enterobacteriaceae are moderately spread in Lebanon and the predominant mechanism is OXA-48 production
