Creating a curriculum based library instruction plan for medical students
[Excerpt] There are multiple situations in which a librarian may find themselves creating a multi-session or longitudinal curriculum-based library instruction program. Maybe you’ve been hoping to do just this very thing for a while, or you stepped into the shoes of a librarian that did this before you, or possibly you’re finding your motivation from an external force. You might be facing this challenge with years of teaching experience or not. No matter what the situation, this chapter will provide tips and strategies for developing a well-rounded library instruction program that focuses on the use of both information literacy skills and evidence based practice principles

Developing a Best Practices Plan for Tutorials in a Multi-Library System
In 2010, the University of Iowa's library system administration created a task force to conduct a reevaluation of tools and spaces used for video tutorial creation across a multi-library system. Following this effort, a working group was charged with improving documentation and staff awareness of resources for developing video tutorials. The group observed that librarians were often independently creating videos that were variable in quality, lacked consistent branding, and were not often shared with others. This article will describe experiences at the Hardin Library for the Health Sciences at the University of Iowa in selecting video tutorial software, and striving to establish a more structured process, including team-developed guidelines, for tutorial creation in a multi-library system. Project limitations and areas for future work will also be presented
Informal Influences in the Process of IDIQ Contractor Selection for Task Award
The selection of a contractor for task award using the Indefinite Delivery Indefinite Quantity (IDIQ) contract often involves dynamics and relationships that are difficult to understand. There are unanswered questions that relate to how government agents define best value to the government. The selection decisions often differ between government agents. The government streamlined the acquisition process by creating the multiple award IDIQ contract. Government agents are relied upon to make sound business judgments in determining which contractor represents the best value to the government. Informal influences can impact the determination of the final selection of a contractor. This thesis attempts to create a better conceptual framework for the informal influences that affect the dynamic selection process of contractors for task award. The research consisted of interviews with members of government agencies that routinely make IDIQ contract task awards. Results indicate that informal, or soft, factors play a large role in determining which contractor will be awarded a task. The most influential factors that affect task award are identified and discussed in depth. The research determined that some marketing processes can be totally ineffective or even counterproductive at times. The results also show that formal rating systems are often replaced by informal peer networks. Existing research on selection processes in the private sector proved comparable to processes used at the government agencies participating in this study
Sound and human impacts on beluga whales in Cook Inlet, Alaska
Thesis (Ph.D.) University of Alaska Fairbanks, 2015Cook Inlet beluga whales (CIBs) are a geographically and genetically isolated population residing in Cook Inlet, Alaska year round. The population declined by approximately 50% between 1994 and 1998 and was listed as endangered under the Endangered Species Act in 2008. The original decline was attributed to overharvest; however, the population has failed to rebound despite the virtual absence of harvest since 1998. This suggests that other factors, such as declining prey availability, increased predation, contaminants, disease, climate change, catastrophic events, habitat loss, unauthorized take, and underwater noise pollution, may be limiting the population's recovery. The goal of this dissertation research was to study the potential impacts of underwater noise on the CIB population. The objective of Chapter 1 was to study CIB acoustic behavior to gain a greater understanding of how CIBs utilize sound. The objective of Chapter 2 was to measure underwater sound levels in Cook Inlet to understand the background noise levels with which CIBs must cope. The objective of Chapter 3 was to document reactions of CIBs to noise disturbance utilizing local ecological knowledge to allow insight into the potential impacts of noise on beluga behavior. The results of Chapter 1 showed that belugas exhibit significant seasonal and spatial variation in calling behavior which suggested differences in habitat usage or differences in the surrounding environment, including background noise levels. The results of Chapter 2 showed that root mean square sound pressure levels exhibited high variation with the highest levels recorded in the 100 Hz frequency band. The seasonal differences in sound levels observed in this study were likely due to greater small vessel traffic and oil and gas development activities in the summer than the winter. In Chapter 3, participants reported observations of CIBs exhibiting avoidance reactions to noise sources including boats, planes, explosions, pile driving, construction, and cars. The results of this chapter showed that noise is perceived to alter beluga behavior and possibly beluga distribution in Cook Inlet. This dissertation research showed that underwater noise has the potential to affect CIBs, however the cost of this impact remains unclear and warrants further study. In light of the lack of support for many of the proposed factors limiting the population and the need for further research for many of these factors, it would be valuable to consider the cumulative effects of these multiple stressors. While their potential impact may be small individually, when combined, these factors may have a synergistic and significant impact on individual whales and, in turn, on the CIB population. Management of cumulative effects may be necessary to ensure the recovery of this endangered population.Introduction -- References -- Chapter 1 : Spatial and temporal patterns in the acoustic behavior of beluga whales, Delphinapterus leucas, in Cook Inlet, Alaska -- Chapter 2: Underwater ambient sound levels in Trading Bay and Eagle Bay in Cook Inlet, Alaska and possible implications for beluga whales

Association of Factor V Secretion with Protein Kinase B Signaling in Platelets from Horses with Atypical Equine Thrombasthenia.
BackgroundTwo congenital bleeding diatheses have been identified in Thoroughbred horses: Glanzmann thrombasthenia (GT) and a second, novel diathesis associated with abnormal platelet function in response to collagen and thrombin stimulation.Hypothesis/objectivesPlatelet dysfunction in horses with this second thrombasthenia results from a secretory defect.AnimalsTwo affected and 6 clinically normal horses.MethodsEx vivo study. Washed platelets were examined for (1) expression of the αIIb-β3 integrin; (2) fibrinogen binding capacity in response to ADP and thrombin; (3) secretion of dense and α-granules; (4) activation of the mammalian target of rapamycin (mTOR)-protein kinase B (AKT) signaling pathway; and (5) cellular distribution of phosphatidylinositol-4-phosphate-3-kinase, class 2B (PIK3C2B) and SH2 containing inositol-5'-phosphatase 1 (SHIP1).ResultsPlatelets from affected horses expressed normal amounts of αIIb-β3 integrin and bound fibrinogen normally in response to ADP, but bound 80% less fibrinogen in response to thrombin. α-granules only released 50% as much Factor V as control platelets, but dense granules released their contents normally. Protein kinase B (AKT) phosphorylation was reduced after thrombin activation, but mTOR Complex 2 (mTORC2) and phosphoinositide-dependent kinase 1 (PDK1) signaling were normal. SH2-containing inositol-5'-phosphatase 1 (SHIP1) did not localize to the cytoskeleton of affected platelets and was decreased overall consistent with reduced AKT phosphorylation.Conclusions and clinical significanceDefects in fibrinogen binding, granule secretion, and signal transduction are unique to this thrombasthenia, which we designate as atypical equine thrombasthenia
Bone Vascularization and Its Effect on Fracture Healing
In operative procedures the surgeon tries to find a convenient and favourable way to reach the organ to be treated. Especially in the extremities he has to use planes of cleavage chosen in such a way, that the tissues are left intact as a unit as much as possible. Only here and there on this way - which is sometimes called the physiological approach - impediments are to be found, mainly formed by neuro-vascular bundles running between the muscles and entering them
On the galloping instability of two-dimensional bodies having elliptical cross sections.
Galloping, also known as Den Hartog instability, is the large amplitude, low frequency oscillation of a structure in the direction transverse to the mean wind direction. It normally appears in the case of bodies with small stiffness and structural damping, when they are placed in a flow provided the incident velocity is high enough. Galloping depends on the slope of the lift coefficient versus angle of attack curve, which must be negative. Generally speaking this implies that the body is stalled after boundary layer separation, which, as it is known in non-wedged bodies, is a Reynolds number dependent phenomenon. Wind tunnel experiments have been conducted aiming at establishing the characteristics of the galloping motion of elliptical cross-section bodies when subjected to a uniform flow, the angles of attack ranging from 0° to 90°. The results have been summarized in stability maps, both in the angle of attack versus relative thickness and in the angle of attack versus Reynolds number planes, where galloping instability regions are identified
