Reflection, Rhetoric or Reality : A Case Study in Preservice Teacher Education

Over the last decade, the term \u27reflection\u27, has reemerged as a central focus surrounding the issue of providing a practical, technical oriented teacher preparation program, as opposed to a liberal, socially oriented, type education (Richardson, 1990). Whilst there has been much support for the image of the teacher as a reflective professional (Schon, 1983), there appears to be no definitive\u27 description as to what constitutes reflective practice, or scholarly consensus as to the ways and means by which teacher educators might encourage its development. It has been described as difficult (Wildman & Niles, 1987), fuzzy (Tom, 1987), problematic (Ross, 1989), knotty (Bullough, 1989) and a slippery and chaotic (Smyth, 1989) concept to pin down. Just as the concept of teaching can and indeed does mean different things to different people in different situations, so too does the concept of reflection and the image of the teacher as a reflective professional (Vaughan,1990:210)

Transference and Psychological-Mindedness in Teachers

The article is an argument for the relevance for our understanding of the pedagogic relationship of Freud’s discovery of transference. Commonalities between teaching and psychoanalysis are reviewed prior to a discussion of how the concept of transference might be applied to teaching, particularly to improving the teacher’s ‘psychological-mindedness’. The article concludes by considering the moral/professional issue of teachers making use of the transference processes at work in their classrooms

An Examination of the Relationship Between Physician Assistant Program Characteristics and Performance on the Physician Assistant National Certifying Examination

One of the most highly regarded indicators of a physician assistant (PA) training program’s quality is the record of success of its graduates in passing the Physician Assistant National Certifying Examination (PANCE). Similar to other professional examinations such as the bar examination and the certified public accountant examination, the PANCE can provoke a great deal of anxiety for both new graduates and program administrators. Successful completion of the PANCE is a prerequisite for licensure in all 50 states and represents a final hurdle for students seeking to begin their new healthcare career. To promote transparency and to protect consumers, the Accreditation Review Commission on Education for the Physician Assistant (ARC-PA) requires that all PA programs publicly display their program’s PANCE pass rate data for the past 5 years. The Physician Assistant Education Association (PAEA) requires that PA programs complete annual reports related to curriculum, administration, and personnel, making a wide variety of statistical data available for public review. Information presented includes admissions requirements, program duration, faculty-student ratios, the proportion of faculty having a doctoral degree, and the length of time a program has been in operation. Unfortunately, there have been relatively few studies that have attempted to determine whether any of these factors predict successful outcomes for PA programs. To date, most studies that have examined predictors of success on the PANCE are either very dated, are limited to single institutions, or have explored only individual program characteristics such as student GPA or admissions criteria. There has not been a recent large-scale, systematic study which has attempted to determine whether any relationships can be drawn between readily available public data and PANCE performance. This study examined data from all PA programs with 5 or more years of PANCE data to determine whether a relationship exists between required clinical experience, student to faculty ratios, duration of the program curriculum, faculty credentials, and 5-year PANCE average pass rates

Randomized trial of polychromatic blue-enriched light for circadian phase shifting, melatonin suppression, and alerting responses.

Wavelength comparisons have indicated that circadian phase-shifting and enhancement of subjective and EEG-correlates of alertness have a higher sensitivity to short wavelength visible light. The aim of the current study was to test whether polychromatic light enriched in the blue portion of the spectrum (17,000 K) has increased efficacy for melatonin suppression, circadian phase-shifting, and alertness as compared to an equal photon density exposure to a standard white polychromatic light (4000 K). Twenty healthy participants were studied in a time-free environment for 7 days. The protocol included two baseline days followed by a 26-h constant routine (CR1) to assess initial circadian phase. Following CR1, participants were exposed to a full-field fluorescent light (1 × 10 14 photons/cm 2 /s, 4000 K or 17,000 K, n = 10/condition) for 6.5 h during the biological night. Following an 8 h recovery sleep, a second 30-h CR was performed. Melatonin suppression was assessed from the difference during the light exposure and the corresponding clock time 24 h earlier during CR1. Phase-shifts were calculated from the clock time difference in dim light melatonin onset time (DLMO) between CR1 and CR2. Blue-enriched light caused significantly greater suppression of melatonin than standard light ((mean ± SD) 70.9 ± 19.6% and 42.8 ± 29.1%, respectively, p \u3c 0.05). There was no significant difference in the magnitude of phase delay shifts. Blue-enriched light significantly improved subjective alertness (p \u3c 0.05) but no differences were found for objective alertness. These data contribute to the optimization of the short wavelength-enriched spectra and intensities needed for circadian, neuroendocrine and neurobehavioral regulation

Topical Steroids to Treat Granulomatous Mastitis: A Case Report

Idiopathic granulomatous mastitis (IGM) is a rare and chronic benign disease of the breast. Histologically, the disease presents as an intense inflammatory reaction with non-caseated granulomas that are the characteristic symptom of the disease. No consensus exists on the best treatment modality for this disease. In this report, we present a patient with granulomatous mastitis who was treated successfully with low-dose oral and topical steroids. Our aim here is to discuss various approaches for IGM in view of the literature and present treatment with topical steroids, which has not been reported

Phenotypic Mismatches Reveal Escape from Arms-Race Coevolution

Because coevolution takes place across a broad scale of time and space, it is virtually impossible to understand its dynamics and trajectories by studying a single pair of interacting populations at one time. Comparing populations across a range of an interaction, especially for long-lived species, can provide insight into these features of coevolution by sampling across a diverse set of conditions and histories. We used measures of prey traits (tetrodotoxin toxicity in newts) and predator traits (tetrodotoxin resistance of snakes) to assess the degree of phenotypic mismatch across the range of their coevolutionary interaction. Geographic patterns of phenotypic exaggeration were similar in prey and predators, with most phenotypically elevated localities occurring along the central Oregon coast and central California. Contrary to expectations, however, these areas of elevated traits did not coincide with the most intense coevolutionary selection. Measures of functional trait mismatch revealed that over one-third of sampled localities were so mismatched that reciprocal selection could not occur given current trait distributions. Estimates of current locality-specific interaction selection gradients confirmed this interpretation. In every case of mismatch, predators were “ahead” of prey in the arms race; the converse escape of prey was never observed. The emergent pattern suggests a dynamic in which interacting species experience reciprocal selection that drives arms-race escalation of both prey and predator phenotypes at a subset of localities across the interaction. This coadaptation proceeds until the evolution of extreme phenotypes by predators, through genes of large effect, allows snakes to, at least temporarily, escape the arms race

Brain processing of contagious itch in patients with atopic dermatitis

Several studies show that itch and scratching cannot only be induced by pruritogens like histamine or cowhage, but also by the presentation of certain (audio-) visual stimuli like pictures on crawling insects or videos showing other people scratching. This phenomenon is coined Contagious itch (CI). Due to the fact that CI is more profound in patients with the chronic itchy skin disease atopic dermatitis (AD), we believe that it is highly relevant to study brain processing of CI in this group. Knowledge on brain areas involved in CI in AD-patients can provide us with useful hints regarding non-invasive treatments that AD-patients could profit from when they are confronted with itch-inducing situations in daily life. Therefore, this study investigated the brain processing of CI in AD-patients. 11 AD-patients underwent fMRI scans during the presentation of an itch inducing experimental video (EV) and a non-itch inducing control video (CV). Perfusion based brain activity was measured using arterial spin labeling functional MRI. As expected, the EV compared to the CV led to an increase in itch and scratching (p \u3c 0.05). CI led to a significant increase in brain activity in the supplementary motor area, left ventral striatum and right orbitofrontal cortex (threshold: p \u3c 0.001; cluster size k \u3e 50). Moreover, itch induced by watching the EV was by trend correlated with activity in memory-related regions including the temporal cortex and the (pre-) cuneus as well as the posterior operculum, a brain region involved in itch processing (threshold: p \u3c 0.005; cluster size k \u3e 50). These findings suggest that the fronto-striatal circuit, which is associated with the desire to scratch, might be a target region for non-invasive treatments in AD patients. © 2017 Schut, Mochizuki, Grossman, Lin, Conklin, Mohamed, Gieler, Kupfer and Yosipovitch
