Using Rhetorical Flexibility to Bridge Advanced Reading/Writing/Grammar with English 101

By successfully completing Level 5 of the five-level intensive English program at the Applied English Center (AEC), students can fulfill the university’s ESL requirement and exit the IEP. As a new coordinator to AECR 151, Level 5 Reading/Writing/Grammar, I felt unsure of where students were going after they left the IEP. I knew very little about the English Department and even less about English 101. What were students being asked to do? Were they struggling? Were they thriving? Did we prepare them well? To get a better sense of this, I met with Sonya Lancaster, Associate Director of Freshmen-Sophomore English. Through our discussion, I quickly realized that our students were only being equipped with a specific range of English skills: skills that prepared them to write structurally and grammatically sound essays based on prompts that were given to them. What English 101 requires students to do is to use language to think outside of the box and to use rhetorical flexibility. I was new to this term, but I have now embraced this as one of the central pieces of our L5 writing curriculum

Von Willlebrand Adhesion to Surfaces at High Shear Rates Is Controlled by Long-Lived Bonds

Von Willebrand factor (vWF) adsorbs and immobilizes platelets at sites of injury under high-shear-rate conditions. It has been recently demonstrated that single vWF molecules only adsorb significantly to collagen above a threshold shear, and here we explain such counterintuitive behavior using a coarse-grained simulation and a phenomenological theory. We find that shear-induced adsorption only occurs if the vWF-surface bonds are slip-resistant such that force-induced unbinding is suppressed, which occurs in many biological bonds (i.e., catch bonds). Our results quantitatively match experimental observations and may be important to understand the activation and mechanical regulation of vWF activity during blood clotting

Managing One-to-One Initiatives: Implementation Analysis Through Expert Elicitation

A qualitative phenomenological study was conducted to identify and analyze issues in the implementation of one-to-one computing initiatives and provide solutions for improvement. An understanding of the implementation process was developed through the analysis of data collected through 27 interviews with teacher experts in the field who have worked with the implementation of one-to-one programs. Teachers were purposely selected from the following groups: those who were completing their first year of teaching, those who had between two and ten years of teaching experience, and those who had eleven plus years of total teaching experience. This study distinctly addresses one-to-one initiatives from both placing importance on the utilization of negative knowledge and in simultaneously treating teacher perceptions as a valid reality. Issues associated with the implementation of one-to-one initiatives develop at a faster speed than traditional school structures are accustomed to respond to. Successful one-to-one management requires a responsive, interconnected, and efficient organizational structure. This research has significance for the improvement of one-to-one initiative implementation efforts. The findings contained in this research have the potential to benefit teachers, administrators, and other stakeholders associated with the implementation of one-to-one initiatives

Polymer Fiber Probes Enable Optical Control of Spinal Cord and Muscle Function In Vivo

Restoration of motor and sensory functions in paralyzed patients requires the development of tools for simultaneous recording and stimulation of neural activity in the spinal cord. In addition to its complex neurophysiology, the spinal cord presents technical challenges stemming from its flexible fibrous structure and repeated elastic deformation during normal motion. To address these engineering constraints, we developed highly flexible fiber probes, consisting entirely of polymers, for combined optical stimulation and recording of neural activity. The fabricated fiber probes exhibit low-loss light transmission even under repeated extreme bending deformations. Using our fiber probes, we demonstrate simultaneous recording and optogenetic stimulation of neural activity in the spinal cord of transgenic mice expressing the light sensitive protein channelrhodopsin 2 (ChR2). Furthermore, optical stimulation of the spinal cord with the polymer fiber probes induces on-demand limb movements that correlate with electromyographical (EMG) activity.National Science Foundation (U.S.) (EEC-1028725)National Science Foundation (U.S.) (Career Award)National Science Foundation (U.S.) (DMR-0819762)McGovern Institute for Brain Research at MIT (Neurotechnology Grant)Massachusetts Institute of Technology.

Electrically pumped continuous wave quantum dot lasers epitaxially grown on patterned, on-axis (001) Si

High performance III-V lasers at datacom and telecom wavelengths on on-axis (001) Si are needed for scalable datacenter interconnect technologies. We demonstrate electrically injected quantum dot lasers grown on on-axis (001) Si patterned with {111} v-grooves lying in the [110] direction. No additional Ge buffers or substrate miscut was used. The active region consists of five InAs/InGaAs dot-in-a-well layers. We achieve continuous wave lasing with thresholds as low as 36 mA and operation up to 80°C

Tool-less Double Sided Board Retainer

Disclosed is a retainer that allows retention of two daughter circuit boards on either side of a main circuit board. The retention device allows the daughter boards to align with each other, minimizing the space required on the main board
