As a result of the ongoing Syrian civil war, almost 3 million refugees moved to Turkey since 2011 because of security reasons. However, the government operated refugee camps have been largely inadequate to accommodate this huge number of refugees. Therefore, almost 91% of the Syrian refugees live out of government-operated camps. According to a Turkish Disaster and Emergency Management Agency (AFAD) report, 45.4% of the children under 5 years old who live out of camps are not vaccinated against polio. This presents a serious health threat to the local population and the whole region. In order to deal with ...

Using Workers’ Compensation Claims Data To Characterize Occupational Injuries In The Biofuels Industry, Sai K. Ramaswamy, Gretchen A. Mosher

Agricultural and Biosystems Engineering Publications

Biofuels production is a fast growing and emerging industry. Occupational injuries are a serious problem due to their human, financial and social costs, yet little research has been published on injuries in the biofuels industry. Learning from past injuries are essential for preventing future occurrences, but the lack of injury information hinders this effort in the biofuels industry. The present study addresses this knowledge gap by utilizing data from over 900 workers’ compensation claims reported from 2008 to 2016 by ethanol and biodiesel facilities in the U.S. to characterize injury costs and severity. The total amount paid for each ...

Traditionally, vaccination strategies require an initial priming vaccination followed by an antigen boost to generate adequate immunity. Here we describe vaccination against a self-peptide for reproductive sterilization utilizing a three-stage vaccine platform consisting of gonadotropin releasing hormone multiple antigenic peptide (GnRH-MAP) as a soluble injection coupled with subcutaneous administration of polyanhydride-immobilized GnRH-MAP and a cyto-exclusive implant containing GnRH-MAP dendrimer-loaded polyanhydride. This strategy generated and maintained cell-mediated and humoral immunity for up to 41 weeks after a single vaccination in mice with enhanced antibody avidity over time. All intact implants had a grossly visible tissue interface with neovascularization and lymphocytic aggregates ...

The Affordances Of Process-Tracing Technologies For Supporting L2 Writing Instruction, Jim R. Ranalli, Hui-Hsien Feng, Evgeny Chukharev-Khudilaynen

English Publications

The research literature on L2 writing processes contains a multitude of insights that could inform writing instruction, but writing teachers are constrained in their capacity to make use of these insights insofar as they lack detailed information about how their students’ actually engage in the processes of writing. At the same time, writing-process researchers have been using powerful technologies to trace writers’ process engagement—namely, keystroke-logging and eye-tracking—that are potentially applicable in educational settings. In this article, we describe a pilot effort to integrate these technologies into L2 writing instruction with college-level ESL students. In addition to illustrating three ...

Power take-off (PTO) is a common method of transferring power from a tractor to a towed piece of machinery. The PTO is also a well-documented cause of severe and often permanent disabling injuries to farm operators. The physical conditions that cause entanglements are not well established. Several studies have explored the parameters of PTO entanglements as materials have been drawn across a rotating PTO knuckle to test for entanglement probability. The objective of this study was to determine probability of entanglement when materials are dropped vertically onto a PTO knuckle spinning at 540 rpm. A total of 360 randomized trials ...

Analysis Of Safety Decision-Making Data Using Event Tree Analysis, Gretchen A. Mosher, Nir Keren

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Predicting and analyzing employee safety decision-making is an important component of managing safety in the workplace. This presentation will discuss the process of transforming existing safety decisionmaking data into an event tree pathway. Event tree analysis methodology is utilized to identify contributing factors in complex systems, illustrate interrelationships of the causes of specified events, and to quantify probabilities of occurrence for each pathway of events. Once pathways are constructed and probabilities for each are estimated, safety decision paths with the highest probabilities can be targeted for educational intervention. Thus, the use of safety decision-making data with event tree analysis has ...
