Democratic Schooling: Toward a Renewed End-in-View

American political leaders and editorial pundits routinely decry the demise of democratic life in the nation. Voting, at all levels, remains at abysmally low levels. Public rhetoric routinely is shrill, often unseemly; it lacks civility. Political discourse in such an environment is clearly impoverished. Combatants for public attention and approval war over visions of the public good. They stand entrenched and immobile, refusing to yield or shift positions. Their ground of disputation frequently is neither level nor common. These tortured circumstances of civic reality are viewed much too often and like so many past and present social problems, as the singular responsibility of the nation\u27s schools. In this view, simply, critics scream their conclusion: schools have failed America. The American democratic fabric is unraveling, so goes the charge, and American schooling is responsible for the mess. Education professionals, too, recently have waded back into this inflamed rhetorical fray. These educators appear unwilling to accept as accurate the vicious allegations of schools\u27 ruin and worthlessness. Moreover, they seek to contribute to the restoration of democracy in America. Only recently has the concept of democratic schooling reemerged in the educational dialogue after several decades of dormancy. The rhetoric of the profession now promotes if not lauds democratic administration, classroom teaching, and teacher and student decision making. Books and articles revealing this rhetoric appear with greater frequency. Why has this dialogue so recently reappeared in educational discourse

Where in the World is the Black Educator? Teacher Shortage as Manufactured Crisis

This exploration of “teacher shortage as manufactured crisis” uses five narratives from the archives that have arisen from one Midwestern (but still, decidedly, Border South) urban center: the St. Louis, Missouri, region. These narratives are an attempt to tap into Sankofa while looking toward a more just and equitable futur

The United States Chiropractic Workforce: An alternative or complement to primary care?

UnlabelledBackgroundIn the United States (US) a shortage of primary care physicians has become evident. Other health care providers such as chiropractors might help address some of the nation's primary care needs simply by being located in areas of lesser primary care resources. Therefore, the purpose of this study was to examine the distribution of the chiropractic workforce across the country and compare it to that of primary care physicians.MethodsWe used nationally representative data to estimate the per 100,000 capita supply of chiropractors and primary care physicians according to the 306 predefined Hospital Referral Regions. Multiple variable Poisson regression was used to examine the influence of population characteristics on the supply of both practitioner-types.ResultsAccording to these data, there are 74,623 US chiropractors and the per capita supply of chiropractors varies more than 10-fold across the nation. Chiropractors practice in areas with greater supply of primary care physicians (Pearson's correlation 0.17, p-value < 0.001) and appear to be more responsive to market conditions (i.e. more heavily influenced by population characteristics) in regards to practice location than primary care physicians.ConclusionThese findings suggest that chiropractors practice in areas of greater primary care physician supply. Therefore chiropractors may be functioning in more complementary roles to primary care as opposed to an alternative point of access

Normalization of prostate specific antigen in patients treated with intensity modulated radiotherapy for clinically localized prostate cancer

<p>Abstract</p> <p>Background</p> <p>The purpose of this study was to determine the expected time to prostate specific antigen (PSA) normalization with or without neoadjuvant androgen deprivation (NAAD) therapy after treatment with intensity modulated radiotherapy (IMRT) for patients with clinically localized prostate cancer.</p> <p>Methods</p> <p>A retrospective cohort research design was used. A total of 133 patients with clinical stage T1c to T3b prostate cancer (2002 AJCC staging) treated in a community setting between January 2002 and July 2005 were reviewed for time to PSA normalization using 1 ng/mL and 2 ng/mL as criteria. All patients received IMRT as part of their management. Times to PSA normalization were calculated using the Kaplan-Meier method. Significance was assessed at p < 0.05.</p> <p>Results</p> <p>Fifty-six of the 133 patients received NAAD (42.1%). Thirty-one patients (23.8%) received radiation to a limited pelvic field followed by an IMRT boost, while 99 patients received IMRT alone (76.2%). The times to serum PSA normalization < 2 ng/mL when treated with or without NAAD were 298 ± 24 and 302 ± 33 days (mean ± SEM), respectively (p > 0.05), and 303 ± 24 and 405 ± 46 days, respectively, for PSA < 1 ng/mL (p < 0.05). Stage T1 and T2 tumors had significantly increased time to PSA normalization < 1 ng/mL in comparison to Stage T3 tumors. Also, higher Gleason scores were significantly correlated with a faster time to PSA normalization < 1 ng/mL.</p> <p>Conclusions</p> <p>Use of NAAD in conjunction with IMRT leads to a significantly shortened time to normalization of serum PSA < 1 ng/mL in patients with clinically localized prostate cancer.</p

Excitation spectrum of bosons in a finite one-dimensional circular waveguide via the Bethe ansatz

The exactly solvable Lieb-Liniger model of interacting bosons in one-dimension has attracted renewed interest as current experiments with ultra-cold atoms begin to probe this regime. Here we numerically solve the equations arising from the Bethe ansatz solution for the exact many-body wave function in a finite-size system of up to twenty particles for attractive interactions. We discuss the novel features of the solutions, and how they deviate from the well-known string solutions [H. B. Thacker, Rev. Mod. Phys.\ \textbf{53}, 253 (1981)] at finite densities. We present excited state string solutions in the limit of strong interactions and discuss their physical interpretation, as well as the characteristics of the quantum phase transition that occurs as a function of interaction strength in the mean-field limit. Finally we compare our results to those of exact diagonalization of the many-body Hamiltonian in a truncated basis. We also present excited state solutions and the excitation spectrum for the repulsive 1D Bose gas on a ring.Comment: 13 pages, 12 figure

Stomatal Conductance of Malosma laurina in Frequently Burned and Non-frequently Burned Sites

In the months following the Malibu fires, the fire zones have experienced and abundance of new growth. Among this new growth, there are differences that can be observed when comparing the top of the Malibu hill (frequent fire zone) to the base of the hill (nonfrequent fire zone). As the chaparral resprouted we noticed the behavior of the Malosma laurina in both frequent and non-frequent fire zones and stomatal conductance, height, and water potential were tested for plants in the two varying zones, with plants in the non-frequent fire zone outperforming their counterparts

Network + Publication + Ecosystem: Curating Digital Pedagogy, Fostering Community

We are excited to share our work on Digital Pedagogy in the Humanities (DPiH), which was published on the Humanities Commons in 2020 by the Modern Language Association after almost a decade of work. DPiH is a large-scale scholarly project that presents the stuff of teaching (syllabi, assignments, and resources) through a curated set of keywords such as “Poetry,” “Disability,” “Queer,” and “Annotation,” among many others. For each keyword, a curator or set of curators has selected and annotated ten pedagogical artifacts; created a curator’s selection statement; and presented a list of related resources. With a lengthy introduction to DPiH that historicizes and contextualizes the project, the edited collection, as a whole, presents a broad array of pedagogical practices that engage technology and offer concrete resources to faculty who would like to expand their existing teaching practices. In this piece, we would like to consider how the project, in its design and implementation, challenges existing ideas about scholarship, pedagogy, and our shared ecosystem of scholarly communication

Introduction to The State of the Syllabus Special Edition

Positioning the syllabus as a key artifact in the modern academy, one that encapsulates many elements of intellectual, scholarly, social, cultural, political, and institutional contexts in which it is enmeshed, we offer in this special issue of Syllabus a set of provocations on the syllabus and its many roles. Including perspectives from full-time and part-time faculty, graduate students, and librarians, the issue offers a multifaceted take on how the syllabus is presently used and might be reimagined

The time-reversal test for stochastic quantum dynamics

The calculation of quantum dynamics is currently a central issue in theoretical physics, with diverse applications ranging from ultra-cold atomic Bose-Einstein condensates (BEC) to condensed matter, biology, and even astrophysics. Here we demonstrate a conceptually simple method of determining the regime of validity of stochastic simulations of unitary quantum dynamics by employing a time-reversal test. We apply this test to a simulation of the evolution of a quantum anharmonic oscillator with up to $6.022\times10^{23}$ (Avogadro's number) of particles. This system is realisable as a Bose-Einstein condensate in an optical lattice, for which the time-reversal procedure could be implemented experimentally.Comment: revtex4, two figures, four page
