Professional Friction: Racialized Discourse and the Practice of Teaching Art

Language is crucial in situating our selves and others. Discursive patterns create alliances or factions, establish hierarchies, and subjugate individuals or groups. In this autoethnographic study, I consider how I, as a White woman teaching art, participate in, maneuver, and manipulate spoken and unspoken racialized discourses within the context of a high school with a diverse population of students. Through the data collection process of journaling over one school year, I recorded reflections on conversations, speeches, and written communication with, between, and regarding teachers, students, parents, and school administrators. I employed discourse analysis on these texts and draw upon Critical Race Theory and Whiteness Studies to examine the discourses that govern the school and inform its social conventions as manifested in my professional identity as it intersects with various collegial spaces. I also show the value in performing an autoethnography as a way to evolve as a social justice educator and scholar as well as a means to give voice to teachers’ stories so that we can render visible the way radicalized discourses and discords they create can shape the daily practice of teaching art

Nocturne Series

My oil paintings explore the mingling of interior and exterior space. Each work in this group focuses upon nocturne scenes with the inclusion of reflections. Inspiration for my work comes from photographs I have taken while walking around at night or from the windows of the space I am in. I have also layered images to develop my own created spaces. Surrealism has played a prominent role in the development of these artworks. The elongated canvases reference the human form and the presence of the viewer in front of the work. With the size of the canvas in mind, I included the human figure in several of these works. The idea and feeling of isolation are present throughout each of my artworks. My hope is that the color palette, the inclusion of the figure, and the size of the canvas will evoke an emotional or visceral reaction from the viewer

Using Constant Time Delay for Teaching High Frequency Sight Word Recognition to Students with Learning Disabilities

In order to have strong reading fluency and comprehension skills, readers must be able to quickly identify words by sight. These essential sight word recognition skills can be difficult for students with learning disabilities, and they may require more intensive intervention strategies. Many studies have been conducted about teaching word recognition skills to students, but no studies were found using constant time delay with elementary age students with learning disabilities. The purpose of this study was to evaluate the effectiveness of using constant time delay as a strategy for teaching high frequency sight word recognition skills to students with learning disabilities. This study used a quantitative, single case, multiple probe research design in which intervention was applied to one student at a time. All five participants in the study showed an increase in their word recognition skills during the intervention, and maintained the ability to read the words after the intervention was completed

Effects of chlorothalonil (CTN) and butylated hydroxy-toluene (BHT) on microbial communities involved in the deterioration of wood using terminal restriction fragment length polymorphism (T-RFLP) analyses

The effects of an organic biocide (CTN) with and without coded antioxidant (BHT) on microbial communities in SYP were assessed using terminal restriction fragment length polymorphism (T-RFLP) analyses in both field and accelerated decay laboratory studies. Ammoniacal copper quaternary (ACQ-C) was used as a positive control in the field study component, but not in the laboratory test. Field stakes were treated with 0.25 and 0.37% ammoniacal copper quat (ACQ-C), CTN (0.1 and 0.25%), CTN (0.1 and 0.25%) with 2% BHT added, 2% BHT alone, and controls were left untreated. In the field studies, preservative treatment slowed the initial colonization of wood by fungi. Higher species richness and diversity were found in non-biocidal treatments (BHT and untreated controls). Fungal communities in treated wood were different based on their species composition, but eventually became more similar to untreated controls. Preservative treatment increased richness and diversity of basidiomycete fungi, but overall presence of basidiomycetes was low compared to other fungi. Preservatives did not change the species composition of basidiomycetes compared to untreated controls. Preservative treatment initially increased bacterial richness and diversity, but over time these trends diminished to levels consistent with untreated controls. Preservatives changed the species composition of colonizing bacteria so that treated and untreated communities remained different over 15 months of soil exposure. Bacterial diversity was negatively correlated with CTN depletion at the lowest rate. In the accelerated decay laboratory test, the effects of CTN and/or BHT on bacterial, fungal, and basidiomycete communities in composted and uncomposted soil were evaluated over a 12 month period. Composted soil had less fluctuation in changing microbial diversity due to more constant moisture. The consensus of the analyses of the bacterial, fungal, and basidiomycete communities indicate that wood preservatives increased microbial species richness and diversity. Preservative treatment increased species turnover that decreased over time. Eventually, microbial communities approached a stable community structure consistent with untreated controls. Preservatives were completely degraded after 30 days exposure; however, definite changes in bacterial and fungal richness, diversity, and species composition were found. Basidiomycetes again represented the smallest portion of the microbial community involved in the overall decay process

Mechanistic chemistry of some transition metal complexes

Part I. Reactions of (alpha)-hydroxyalkylchromium(III) complexes;A. Acidolysis and homolysis;The reactivity of several pentaaquo-(alpha)-hydroxyalkylchromium(III) complexes including (H(,2)O)(,5)CrCH(C(,2)H(,5))OH(\u272+), CrC(CH(,3))(C(,2)H(,5))OH(\u272+), CrC(C(,2)H(,5))(,2)OH(\u272+), CrC(CH(,3))(i-C(,3)H(,7))OH(\u272+) and CrC(CH(,3))(t-C(,4)H(,9))OH(\u272+) was examined. The chromium-carbon bond was found to cleave by both heterolytic and homolytic pathways. The heterolytic pathway, in general termed acidolysis, is the common mode of decomposition of most pentaaquoalkylchromium(III) complexes. The products of acidolysis are such that the reaction may be formally viewed as the protonation of the carbanion bonded to chromium(III). The homolytic pathway was studied through the use of oxidizing scavengers which reacted with the products of homolysis (Cr(\u272+) and R(.)), but not directly with the alkylchromium(III) complexes. Thus, by proper selection of reaction conditions, rate constants for both pathways were determined. In most cases, the homolysis rate constants were much greater in magnitude than the acidolysis values. The homolysis rate constants were found to be strongly influenced by steric effects. At 25.0(DEGREES)C, the rate constants varied (TURN)10(\u277) with CrCH(,2)OH(\u272+) (k(,hom) = 3.7 x 10(\u27-5) s(\u27-1)), the least substituted complex having the slowest homolysis rate and CrC(CH(,3))(t-C(,4)H(,9))OH(\u272+) (k(,hom) (TURN)3 x 10(\u272) s(\u27-1)) having the fastest homolysis rate;One (alpha)-alkoxyalkylchromium(III) complex, CrC(CH(,3))(,2)OCH(CH(,3))(,2)(\u272+), was also studied. This complex was found to have a unique homolysis rate constant (5.77 (+OR-) 0.15 s(\u27-1) at 25.0(DEGREES)C). It was also found to undergo rearrangement in dilute perchloric acid to CrC(CH(,3))(,2)OH(\u272+). At mechanism analogous to similar acid-catalyzed cleavage of dialkylethers is presented;B. Reactions with Cu(\u272+) or Fe(\u273+);The reactions of five alkylchromium(III) complexes with Cu(\u272+) or Fe(\u273+) were investigated. The predominant pathway for reactions with both oxidants was found to be inversely dependent on the acid concentration in the range studied. Two different mechanisms are proposed to explain the results obtained. The Cu(\u272+) reactions occur by binding of Cu(\u272+) to the (alpha)-hydroxyl oxygen in its basic form. The Fe(\u273+) reactions probably proceed through attack directly at the chromium center;Part II. Binuclear cobalt complexes of Schiff base macrocyclic ligands;Three dicobalt(II) complexes of Schiff base macrocyclic ligands with N(,2)O(,2) chelating sites were prepared. These complexes were all based upon the tetra(salicylideneamino)benzene unit as shown. The;complexes were characterized by their electronic spectra and elemental analysis. The dicobalt(II) complexes are easily converted to the dicobalt(III) analogs using oxidizing agents such as Co(NH(,3))(,5)Cl(\u272+), H(,2)O(,2) and O(,2) in methanol solution. The dicobalt(III) complexes may be re-reduced to the parent dicobalt(II) complexes with CrCl(,2). One organometallic derivative, (CH(,3)Co)(,2)(5-Bu(\u27t)sal(,4))bz, was prepared. It was characterized by its reaction with Hg(II) and its photodecomposition to the dicobalt(II) complex under anaerobic conditions and to dicobalt(III) under aerobic conditions;(\u271)DOE Report IS-T-954. This work was performed under Contract W-7405-eng-82 with the Department of Energy

Variance in student ratings of part-time and full-time instructor effectiveness by teaching field and function at a Midwestern community college

The purpose of this research was to investigate whether differences in teaching effectiveness exist between full-time and part-time community college instructors in specific educational disciplines. The study examined faculty representing a number of teaching fields. Past research investigated the quality of instruction of part-time faculty and full-time faculty but did not investigate the possible differences in quality within the two groups;Student evaluations of instructors at one community college provided a measure of teaching effectiveness. Multiple analysis of variance analyzed part-time and full-time instructor groups, using student evaluations of instructor scores for teaching fields. The data set included scores from 12,460 instructor evaluation forms in twenty-five teaching fields. The procedure applied analysis of variance a two levels of instructor employment; full-time and part-time employment;The results indicated a significant difference in student ratings of full-time and part-time instructors. There was a significant interaction when teaching field effect was included with full-time and part-time employment levels. Full-time instructor ratings were different in eight of the twenty-five teaching fields. The difference in student ratings for arts and sciences versus vocational technical fields was not significant. When contrasting arts and sciences and vocational technical fields with the two employment levels, no significant difference resulted. Although part-time instructor ratings were significantly higher than full-time instructor ratings on a collegewide basis, differences in the means were not large. Groups of instructor ratings within the college provided statistical test results which differed from the collegewide analysis results. This research implied that more accurate statistical information may result from analysis of evaluation ratings of groups within the community college faculty

Secondary Prevention of Arteriosclerosis in Lower Limb Vascular Amputees: A Missed Opportunity

ObjectivesTo determine the numbers of patients with peripheral vascular disease prescribed secondary prevention agents following a lower limb amputation.DesignA retrospective cross sectional study.MethodsThe clinical documentation of 107 vascular amputees (mean age 69.5, 2:1 male:female ratio) referred for prosthesis provision in 2004 and 2005 were analysed to determine levels of prescribing of anti-platelet agents, anti-coagulants and cholesterol lowering drugs.ResultsAnalysis of vascular amputees referred in 2004 and 2005 reveals that 41% were prescribed a statin and 39% were prescribed a statin and 60% an anti-platelet agent. While 39% of these patients were on both drugs, 32% had been prescribed neither.ConclusionsThe medical management of patients with severe peripheral vascular disease, even where their disease has led to an amputation, is sub-optimal

Diagnosis, investigation and management of hereditary spastic paraplegias in the era of next-generation sequencing.

The hereditary spastic paraplegias (HSPs) are a group of genetic conditions in which spastic paralysis of the legs is the principal clinical feature. This is caused by a relatively selective distal axonal degeneration involving the longest axons of the corticospinal tracts. Consequently, these conditions provide an opportunity to identify genes, proteins and cellular pathways that are critical for axonal health. In this review, we will provide a brief overview of the classification, clinical features and genetics of HSP, highlighting selected HSP subtypes (i.e. those associated with thin corpus callosum or cerebellar ataxia) that are of particular clinical interest. We will then discuss appropriate investigation strategies for HSPs, suggesting how these might evolve with the introduction of next-generation sequencing technology. Finally, we will discuss the management of HSP, an area somewhat neglected by HSP research.We thank Rhys Roberts for reviewing the manuscript.
