Reframing New Art Teacher Support: From Failure to Freedom

In order to support new art teachers and encourage them as leaders of contemporary art education curricula, those invested in the preparation and development of beginning art teachers must examine the forces at play in new teachers’ professional lives, as well as the problems with existing support structures. In this article, I present seven perspectives on the new art teacher experience, ranging from feelings of failure, to problems inherent in preparation and induction practices, to issues of teacher identity and socialization, to the pursuit of professional agency within school cultures. I suggest readers view these perspectives as seven artworks hanging in an art studio, considering how one informs the other to create a space where new ideas and possibilities might be imagined

Civic Order and Dispute Resolution in 14th and 15th Century London

Research project funded in academic year 2008-09The University Archives has determined that this item is of continuing value to OSU's history.During the 14th and 15th centuries, London was a city of 40,000 to 60,000 people crowded into one square mile. Tempers could flare quickly, and factional strife was common, with disorder sometimes degenerating into riots such as the Peasants’ Revolt of 1381. Yet during this period, London became a thriving center of commercial trade. How could this have happened? Hanawalt credits a well regulated judicial system through which authorities established respect for their office and defined the boundaries of correct behavior. In her new book Civic Order and Dispute Resolution in Fourteenth- and Fifteenth Century London, Hanawalt investigates the ways in which London promoted a civic culture of order that provided a favorable environment for dispute resolution.Mershon Center for International Security StudiesProject summar

Assessing location attractiveness for manufacturing automobiles

Purpose: Evaluating country manufacturing location attractiveness on various performance measures deepens the analysis and provides a more informed basis for manufacturing site selection versus reliance on labor rates alone. A short list of countries can be used to drive regional considerations for site-specific selection within a country. Design/methodology/approach: The two-step multi attribute decision model contains an initial filter layer to require minimum values for low weighted attributes and provides a rank order utility score for twenty three countries studied. The model contains 11 key explanatory variables with Labor Rate, Material Cost, and Logistics making up the top 3 attributes and representing 54% percent of the model weights. Findings: We propose a multi attribute decision framework for strategically assessing the attractiveness of a country as a location for manufacturing automobiles. Research limitations/implications: Consideration of country level wage variation, specific tariffs, and other economic incentives provides a secondary analysis after the initial list of candidate countries is defined. Practical implications: The results of our modeling shows China, India, and Mexico are currently the top ranked countries for manufacturing attractiveness. These three markets hold the highest utility scores throughout sensitivity analysis on the labor rate attribute weight rating, highlighting the strength and potential of manufacturing in China, India, and Mexico. Originality/value: Combining MAUT with regression analysis to simplify model to core factors then using a “must have” layer to handle extreme impacts of low weight factors and allowing for ease of repeatabilityPeer Reviewe

An Experimental Survey of the Cathodic Activation of Metals Including Mg, Sc, Gd, La, Al, Sn, Pb, and Ge in Dilute Chloride Solutions of Varying pH

The kinetics of the hydrogen evolution reaction (HER) have been reported to increase upon pure magnesium (Mg) surfaces, following prior anodic polarisation or corrosion. This phenomenon is termed anodically induced âÂÂcathodic activationâÂÂ, which is not necessarily an elementary concept. The tendencies of other metals to exhibit cathodic activation has not been systematically explored in the past. In this study, an experimental survey of cathodic activation was conducted for different metals on the basis of understanding the origin of the cathodic activation phenomenon on Mg; including the metals Sc, Gd, La, Al, Sn, Pb and Ge, in 0.1 M NaCl with pH ranging from 3-11. Sc, Gd, La and Mg showed cathodic activation in solutions of various pH, whereas Al showed cathodic activation only in an acidic solution. Sn, Pb and Ge did not show significant cathodic activation across the pH range tested. It is proposed on the basis of the results herein, metals that tend to directly react with water to form hydroxides in aqueous electrolytes have a higher tendency to demonstrate cathodic activation

Learning from Failure in Systems Engineering: A Panel Discussion

This paper summarizes the discussion of the Learning from Failure in Systems Engineering panel that was held in Huntsville, AL on November 8, 2010. The panel objective was to discuss how systems engineers respond to and learn from failure and identify future directions important to the community. The panel consisted of four representatives with experience in government, industry, and academia: (1) Ronald Kadish from Booz Allen Hamilton and former director of the Missile Defense Agency, (2) Gary Payton, retired Deputy Under Secretary of the Air Force for Space Programs, (3) John Thomas from Booz Allen Hamilton and President-elect of INCOSE, and (4) Michael Griffin from the University of Alabama, Huntsville and former NASA Administrator. Each panelist was asked to (i) provide an opening statement and elaborate on their experience with failure, (ii) describe when failure is appropriate, (iii) describe how we learn and react to failure, and (iv) identify and discuss techniques to improve how systems engineers react to failure. Several common themes arose from the discussion including: failure is an option, the importance of failure to allow reassessment, and more process is not the solution. Each of these is discussed in turn along with future directions identified for reacting to and learning from failure

A semi-automated non-radiactive system for measuring recovery of RNA synthesis and unscheduled DNA synthesis using ethynyluracil derivatives

Nucleotide excision repair (NER) removes the major UV-photolesions from cellular DNA. In humans, compromised NER activity is the cause of several photosensitive diseases, one of which is the skin-cancer predisposition disorder, xeroderma pigmentosum (XP). Two assays commonly used in measurement of NER activity are ‘unscheduled DNA synthesis (UDS)’, and ‘recovery of RNA synthesis (RRS)’, the latter being a specific measure of the transcription-coupled repair sub-pathway of NER. Both assays are key techniques for research in NER as well as in diagnoses of NER-related disorders. Until very recently, reliable methods for these assays involved measurements of incorporation of radio-labeled nucleosides. We have established non-radioactive procedures for determining UDS and RRS levels by incorporation of recently developed alkyne-conjugated nucleoside analogues, 5-ethynyl-2′-deoxyuridine (EdU) and 5-ethynyuridine (EU). EdU and EU are respectively used as alternatives for 3H-thymidine in UDS and for 3H-uridine in RRS. Based on these alkyne-nucleosides and an integrated image analyser, we have developed a semi-automated assay system for NER-activity. We demonstrate the utility of this system for NER-activity assessments of lymphoblastoid samples as well as primary fibroblasts. Potential use of the system for large-scale siRNA-screening for novel NER defects as well as for routine XP diagnosis are also considered

Encounters with Care: Mentoring Beginning Art Teachers amid the Pre[CARE]ious Conditions of Neoliberalism

Arguing that significant encounters with care often go unnoticed in a United States’ educational system largely defined by a neoliberal agenda, in this article I undertake a deep investigation of encounters with care that emerged in my experiences mentoring beginning art teachers. I approach these encounters as provocative disturbances that might reveal the nuances and intricacies of the entanglements at work. Through this exploration, I aim to show that these caring entanglements are, in consequential ways, run through with precarity—not only as an existential condition of life, but as a specific set of social, cultural, political, and material relations that produce an unequal distribution of both precarity and care, especially along the lines of gender and race. I conclude by offering provocations for how those who support beginning art teachers might, given the earth-wide and school-specific conditions of precarity, prepare them to navigate the complexities of caring relations in schools

Genomic Selective Constraints in Murid Noncoding DNA

Recent work has suggested that there are many more selectively constrained, functional noncoding than coding sites in mammalian genomes. However, little is known about how selective constraint varies amongst different classes of noncoding DNA. We estimated the magnitude of selective constraint on a large dataset of mouse-rat gene orthologs and their surrounding noncoding DNA. Our analysis indicates that there are more than three times as many selectively constrained, nonrepetitive sites within noncoding DNA as in coding DNA in murids. The majority of these constrained noncoding sites appear to be located within intergenic regions, at distances greater than 5 kilobases from known genes. Our study also shows that in murids, intron length and mean intronic selective constraint are negatively correlated with intron ordinal number. Our results therefore suggest that functional intronic sites tend to accumulate toward the 5' end of murid genes. Our analysis also reveals that mean number of selectively constrained noncoding sites varies substantially with the function of the adjacent gene. We find that, among others, developmental and neuronal genes are associated with the greatest numbers of putatively functional noncoding sites compared with genes involved in electron transport and a variety of metabolic processes. Combining our estimates of the total number of constrained coding and noncoding bases we calculate that over twice as many deleterious mutations have occurred in intergenic regions as in known genic sequence and that the total genomic deleterious point mutation rate is 0.91 per diploid genome, per generation. This estimated rate is over twice as large as a previous estimate in murids
