Distributed Task Related BOLD Signal During Auditory Sub-second Timing

The brain\u27s input/output functions depend heavily on temporal processing. We sought to identify regions of the brain active in task performance during temporal discrimination of a sub-second auditory interval. We presented ten subjects with 40 paired tones and asked them to judge whether these comparison intervals were longer or shorter than a 100 ms standard. We then localized correlations between the Blood Oxygenation Level Dependent signal and task performance across subjects using event-related functional magnetic resonance imaging. We saw no task-related frontal cortex activation and significant activation of traditional auditory areas. Auditory regions included the bilateral superior and middle temporal gyri (STG and MTG): Brodrnann areas (BA) 21, 22, 38, 41 , and 42. The signals within the left hemispheric insula, precentral gyrus, inferior and superior parietal lobes and right hemispheric postcentral gyrus were also correlated with the task. Unexpectedly, visual areas were also activated, including the right hemispheric cuneus, middle occipital gyrus and bilateral precuneus: BA 7, 18 & 19. Most interestingly, the activation of the STG, MTG, precentral gyrus and insula- areas implicated in verbal memory, language and reading - suggests a possible co-localization of function between sub-second temporal processing and written language comprehension. This study thus corroborates the long speculated hypothesis that certain language-based learning disabilities, such as dyslexia, may be caused by deficits in temporal processing

Animating the library’s value: Developing an information literacy cartoon

An academic library was asked to create a brief, compelling, attention-grabbing marketing tool that convinces students to choose library resources over Google. After numerous discussions and a brief student survey, the format of the marketing tool was selected, an animated video, and a ballpark cost was obtained. Year-end funds were allocated for an animated video to be dubbed “Hunt Library vs. Google”. Followed by an abbreviated vendor selection and an arduous down-payment process, collaborative work began. We provided an example video that we wished to emulate. The video showed a student in a boat fishing (narrated as “drowning”) in a sea of information. We wanted to change the boating concept into a flying concept, yet provided little input on how to accomplish this. The animators needed much more guidance, and the fiscal year clock was ticking on our creative endeavor. They were used to serving businesses with a more tangible product. So we took several steps back to educate them on our product, (which is quality information and service,) and our “company,” an aeronautical university library. The librarians did not have experience in this type of creative process. After brainstorming, we provided a few ideas on how flight could enter the new concept, and the animator became intrigued with using birds to express a few points. This presentation will describe several practical considerations, such as costs; types of animation; the creative process (including script, storyboarding, artwork, and voice selection); focus group responses; revisions; release; usage; and ongoing promotion

Expect (and Collect) a Response From Everyone in the Classroom

A positive and descriptive book review of Derek Bruff\u27s 2009 book Teaching with Classroom Response Systems: Creating Active Learning Environments

Bookshelves full? How to rehome, repurpose, and recycle print books.

Storing and moving books that you don\u27t have plans to use again can be a burden. But what is a responsible way to unburden yourself? We will discuss how to donate books for charitable initiatives, online book/textbook swaps, proper recycling techniques, and a few easy crafts using books. Lastly, we will discuss a few steps that libraries and universities are taking to address sustainability

The Acquisition of Phrasal Verbs in L2 English: A Literature Review

This paper introduces the linguistic element called the phrasal verb, which consists of a verb followed by a particle, such as to “eat out.” The challenges facing L2 students attempting to master phrasal verbs are considered, followed by a proposed approach to teaching semantic as well as syntactic understanding of these structures. We conclude with a review of literature which proposes innovative teaching techniques. We conclude that there is promise that some of these techniques can assist students to master phrasal verbs, and that more research is necessary to determine the most effective approaches

A Novel Lifecycle Extension Plan for the Efficient Usage of On-Orbit Post-Consumer Assets

Asteroid mining is a potential form of commercial space industry, and significant amounts of research have gone into the feasibility of that activity. Less research has been done on what happens to the asteroid post-mining; the two primary end-of-life scenarios for the remains of a mined asteroid are not ideal. The remains could be deorbited, which entails complex technical and legal challenges, or they could remain in or-bit, which could lead to collisions and a general increase in space debris. This proposal outlines a solution for the post-consumer asteroid issue which avoids creating more space debris and the risky business of deorbiting. This solution is to use the post-consumer asteroid shell as a shelter for delicate equipment or as a “garbage can in space,” which would hold the remains of defunct satellites until the time they could be more safely deorbited. The shell of the asteroid would provide protection from space debris impacts and some radiation. This proposal also discusses some of the major technical and legal challenges that this solution would face, and how stakeholders could potentially address them. More research is required to gain a better understanding of the challenges and opportunities that this proposal faces, which can be conducted during the long-term development of commercial asteroid mining technologies

Structural and Functional Organization of the Vestibular Apparatus in Rats Subjected to Weightlessness for 19.5 Days Aboard the Kosmos-782 Satellite

The vestibular apparatus was investigated in rats subjected to weightlessness for 19.5 days. The vestibular apparatus was removed and its sections were fixed in a glutaraldehyde solution for investigation by light and electron microscopes. Structural and functional charges were noted in the otolith portions of the ear, with the otolith particles clinging to the utricular receptor surface and with the peripheral arrangement of the nucleolus in the nuclei of the receptor cells. It is possible that increased edema of the vestibular tissue resulted in the destruction of some receptor cells and in changes in the form and structure of the otolith. In the horizontal crista, the capula was separated

Ice Formation in Model Biological Membranes in the Presence of Cryoprotectors

Ice formation in model biological membranes is studied by SAXS and WAXS in the presence of cryoprotectors: dimethyl sulfoxide and glycerol. Three types of phospholipid membranes: DPPC, DMPC, DSPC are chosen for the investigation as well-studied model biological membranes. A special cryostat is used for sample cooling from 14.1C to -55.4C. The ice formation is only detected by WAXS in binary phospholipid/water and ternary phospholipid/cryoprotector/water systems in the condition of excess solvent. Ice formation in a binary phospholipid/water system creates an abrupt decrease of the membrane repeat distance by delta-d, so-called ice-induced dehydration of intermembrane space. The value of delta-d decreases as the cryoprotector concentration increases. The formation of ice does not influence the membrane structure (delta-d = 0) for cryoprotector mole fractions higher than 0.05.Comment: PDF: 9 pages, 3 figures; sourse in MS Wor
