Obsidian Hydration Analysis of Artifacts from Six Sites Between Walters Ferry and King Hill, Idaho.

During the past ten years excavations have been conducted at a number of archaeological sites along the Snake River between Meiba and King Hill, Idaho. Though the majority of point types from these sites are typologically of Late Archaic age (2000-150 BP) few have produced little datable organic material, though all have produced obsidian artifacts and debitage. In some instances projectile points of what are typologically Early and Middle Archaic age have been recovered. This report discusses the results of obsidian hydration analysis of 32 specimens from six sites between Walters Ferry and King Hill, Idaho. The purpose of the study was to establish Chronometrie ages for undated sites and determine if contexts that have produced temporally mixed types actually reflect distinct temporal occupations

A Critique of Microfinance In-Context: Lessons from Kiva in Guatemala

poster abstractThis paper examines the microfinance industry and its recent use of technology in connecting individual lenders to borrowers in developing countries. Special consideration is given to the ethical dimensions and associated risks inherent in these social ventures. In addition, this paper seeks to establish a ‘rubric for effectiveness’ for social ventures in developing countries through the analysis of data, testimonials, and stories from the field. Topics include economic development, poverty alleviation, social efficiency, social capital, information asymmetry, and local neoliberalism. Drawing on the results and conclusions of this study, questions for future research in the field of social entrepreneurship are presented

FROM PATENT TO PRODUCT: COMMERCIALIZING AN INNOVATION IN VASCULAR ACCESS FOR HEMODIALYSIS TREATMENT

poster abstractAs End-Stage Renal Disease (ESRD) affects more than 500,000 patients every year and is currently increasing at a rate of 5-7%, the need for effective hemodialysis treatment remains an important issue in our society. Currently there are two vascular access devices widely accepted by the medical community, the arteriovenous graft (AVG) and arteriovenous fistula (AVF). Dr. Akingba’s innovation, the modular anastomotic valve device (MAVD), would allow for selective shunting during hemodialysis treatment in turn increasing the patency by an expected six fold. The purpose of our research pertaining to this device was to assist Dr. Akingba in preparing the device for commercialization through an analysis of FDA regulations, licensing, technological considerations, and medical device competitors. With this is mind, preliminary research, bench top model, flow dynamic computer simulations, and key interviews were implemented as data sources. Research in hemodialysis techniques, flow dynamics, FDA approval process, and licensing considerations including the valuation of the intellectual property has provided us insight into the most effective pathway to bring the MAVD to market. As a result, a more direct licensing plan was developed for Dr. Akingba to streamline the commercialization process. With this research, Dr. Akingba will be able to obtain FDA clearance through animal testing and clinical trials. Once this device has been brought to market, it will shift preference in vascular access toward usage of the graft for hemodialysis with its increased patency and ultimately bring medical enhancements to patients, surgeons, hospitals, and the health-care industry in general

Febrile Neutropenia

Febrile Neutropenia (FN) is a common, yet potentially life-threatening, complication in cancer patients receiving myelosuppressive chemotherapy. FN occurs when a patient has a temperature of greater than 100.4℉ with an absolute neutrophil count of less than 500cells/mm³, which places the patient at a high risk for infection. Fever may be the only sign of FN. FN is an oncologic emergency, requiring immediate, aggressive treatment with broad-spectrum antibiotics. FN is associated with high morbidity and mortality in cancer patients

A Comment from Mark G. Plew on Kir’yak’s Portable Engravings of the Northeastern Paleoasiatics

Jan Kee and I published a note on incised stones from Idaho (Kee and Plew 2015). The paper was based on a presentation on portable art of Western North America presented at the 2014 SAA meetings and published in JONA. We described four distinct types that occur in different geographic settings in association with different site types and over a period of several thousand years, though more common in the Late Holocene. These included stones with parallel lines located on the face or margins of stones with horizontal, vertical, or diagonal lines—or a combination. A second type was characterized by centrally placed hachure, while a third type consisted of irregular/multidirectional lines lacking discernable patterning. A final type included what appeared to be more decorative—combining zig-zags, ladders, parallel lines and chevrons. Reviewing the Kir’yak paper, there appear some similarities in design motifs to those in Idaho—though all would fit our Type 4 (Figures A, B, and C)—being more decorative items

Facebook Friendships between College/University Instructors and Students: Deciding Whether or Not to Allow Students as Friends, Communicating with Students, and the Individual Differences that Influence Instructors\u27 Impression Management on Facebook

This research examined Facebook friendships between college/university instructors and students. Based on the development of instructor-student dual relationships, this study described instructors’ Facebook use with students. This included explanations for allowing/not allowing students, communication with students, and ethical concerns. Rooted in the theories of impression management, self-monitoring and role conflict, plus the concept of ambient awareness, hypotheses predicted relationships between instructors’ individual differences and Facebook use: (1) self-monitoring would be positively related to role conflict; and (2) self-monitoring, (3) role conflict, and (4) ambient awareness would be positively related to instructors’ self-presentation, impression management behaviors, and privacy management. Emails were sent to faculty at 270 colleges/universities throughout the U.S. and 331 instructors completed the online survey. Of these, 56.2% allowed students as friends. Open-ended answers revealed that instructors allowed students as friends to communicate, to facilitate learning about each other, and because it was difficult to decline requests. Some instructors did not allow certain students (e.g., problematic students, undergraduates). They communicated by commenting on and liking posts on students’ pages, and had ethical concerns about negative consequences. Open-ended answers revealed that instructors did not allow students as friends to maintain the professional divide and avoid favoritism, which explained their ethical concerns. Hierarchical regression analyses tested the predicted relationships. Results revealed that self-monitoring approached significance as having a positive relationship with role conflict and a negative relationship with privacy management, but was not related to self-presentation or impression management behaviors. Role conflict was not related to impression management. Awareness of students was positively related to self-presentation and impression management behaviors, but unexpectedly, perception of students’ awareness of instructors was negatively related to privacy management. A partial correlation analysis tested high/low self-monitors separately and not only replicated the results, but also revealed that high self-monitors’ perception of students’ awareness was positively correlated with self-presentation and impression management behaviors. These findings indicate that ambient awareness is related to online communication and should be studied further. This is especially intriguing since the two types of ambient awareness related differently to the three types of impression management studied in this research

Adapting and optimising Fluidity for high-fidelity coastal modelling

Work undertaken to improve the performance of Fluidity, an open-source finite-element computational fluid dynamics solver from Imperial College London, for both general computational fluid dynamics and tidal modelling problems is outlined. Optimising the general computational structure of Fluidity, along with work to improve the data decomposition and parallel load balancing enabled simulations to be run over three times faster than with the original code, even when using thousands of computational cores. This changes the level of detail at which fluids problems can be studied with Fluidity, and impacts upon research that examines high Reynolds number turbulent flows. This is of particular relevance in areas such as engineering aerodynamics, wind energy, marine energy, and environmental or pollution modelling
