Alone in the Trenches: An Evening with Esera Tuaolo event flyer 2011

Come hear Esera Tuaolo\u27s searing story of terror and hope on Monday, November 28, 2011 at 7:30 PM in Edwards Hall Auditorium. Tuaolo, a Samoan raised on a Hawaiian banana plantation, had a natural talent, football. He went on to play for five NFL teams: the Green Bay Packers, the Minnesota Vikings, the Jacksonville Jaguars, the Carolina Panthers, and the Atlanta Falcons in the 1999 Super Bowl. But for the nine years he played professional football he lived in terror that when his face flashed upon the TV screen, someone would divulge his darkest secret. Esera Tuaolo is gay. Esera will take you inside the homophobic world of professional football and describe fears that almost drove him to suicide. He will evoke heartbreak--how his older brother, Tua, died of AIDS--and hope when, Esera, a deeply devout Christian fell in love and started a family. There will be a Question & Answer session followed by a book signing immediately after Esera\u27s talk

Shuffle operations on discrete paths

AbstractWe consider the shuffle operation on paths and study some parameters. In the case of square lattices, shuffling with a particular periodic word (of period 2) corresponding to paperfoldings reveals some characteristic properties: closed paths remain closed; the area and perimeter double; the center of gravity moves under a 45∘ rotation and a 2 zoom factor. We also observe invariance properties for the associated Dragon curves. Moreover, replacing square lattice paths by paths involving 2kπ/N-turns, we find analogous results using more general shuffles

Funding Nonprofit Radio Technology Initiatives in Canada

Media organizations worldwide are struggling to find sustainable financial models since the arrival of the internet. Nonprofit radio is no different. Using a thematic analysis of 62 Canadian nonprofit stations’ financial statements from 2012–2015, this study examines the impact of the Community Radio Fund of Canada’s Radiometers’ grant competition. Although results show a small financial gain for those who received funding, the study fails to determine the value of relying on such a grant for long-term technological sustainability. This study also shows the classic income effect by demonstrating how stations continued spending on technology whether they received grants or not. Recommendations include creating a matching fund program to encourage stations to find alternative sources of income to sustain their projects and increase accountability.Les organisations de médias à travers le monde luttent pour trouver des modèles financiers durables depuis l’arrivée d’internet. La radio à but non lucratif n’y échappe pas non plus. En effectuant une analyse thématique des états financiers de 62 stations canadiennes à but non lucratif de 2012-2015, cette étude examine l’impact de la compétition Radiomètres du Fonds canadien de la radio communautaire. Malgré le fait que les résultats démontrent un petit gain financier pour ceux ayant reçu du financement, l’étude ne parvient pas à démontrer la valeur de ce type de subvention pour une durabilité technologique à long terme. Cette étude valide aussi l’effet de revenu classique en démontrant que les stations continuent à effectuer des dépenses en technologie, peu importe s’ils ont obtenu ou non une subvention. Les recommandations comprennent la création d’un programme de fonds de contrepartie, afin d’encourager les stations à trouver des sources alternatives de revenus afin de soutenir leurs projets et d’accroître l’imputabilité

Details on the O(meα6){\cal{O}}(m_e \alpha^6) Positronium Hyperfine Splitting due to Single Photon Annihilation

A detailed presentation is given of the analytic calculation of the single-photon annihilation contributions to the positronium ground state hyperfine splitting to order $m_e\alpha^6$ in the framework of non-relativistic effective theories. The current status of the theoretical description of the positronium ground state hyperfine splitting is reviewed.Comment: 27 pages, latex, 5 postscript figures; typos correcte

Treating Homeless Opioid Dependent Patients with Buprenorphine in an Office-Based Setting

CONTEXT Although office-based opioid treatment with buprenorphine (OBOT-B) has been successfully implemented in primary care settings in the US, its use has not been reported in homeless patients. OBJECTIVE To characterize the feasibility of OBOT-B in homeless relative to housed patients. DESIGN A retrospective record review examining treatment failure, drug use, utilization of substance abuse treatment services, and intensity of clinical support by a nurse care manager (NCM) among homeless and housed patients in an OBOT-B program between August 2003 and October 2004. Treatment failure was defined as elopement before completing medication induction, discharge after medication induction due to ongoing drug use with concurrent nonadherence with intensified treatment, or discharge due to disruptive behavior. RESULTS Of 44 homeless and 41 housed patients enrolled over 12 months, homeless patients were more likely to be older, nonwhite, unemployed, infected with HIV and hepatitis C, and report a psychiatric illness. Homeless patients had fewer social supports and more chronic substance abuse histories with a 3- to 6-fold greater number of years of drug use, number of detoxification attempts and percentage with a history of methadone maintenance treatment. The proportion of subjects with treatment failure for the homeless (21%) and housed (22%) did not differ (P=.94). At 12 months, both groups had similar proportions with illicit opioid use [Odds ratio (OR), 0.9 (95% CI, 0.5–1.7) P=.8], utilization of counseling (homeless, 46%; housed, 49%; P=.95), and participation in mutual-help groups (homeless, 25%; housed, 29%; P=.96). At 12 months, 36% of the homeless group was no longer homeless. During the first month of treatment, homeless patients required more clinical support from the NCM than housed patients. CONCLUSIONS Despite homeless opioid dependent patients' social instability, greater comorbidities, and more chronic drug use, office-based opioid treatment with buprenorphine was effectively implemented in this population comparable to outcomes in housed patients with respect to treatment failure, illicit opioid use, and utilization of substance abuse treatment

A Model of Zebra Emission in Solar Type IV Radio Bursts

Solar type IV radio bursts present a theoretical challenge because they are composed of both continuum emission and fine structures. The latter include zebra bursts, which appear as harmonically spaced multiplets that shift in frequency with time. Similarities between these features and terrestrial auroral emissions suggest a new model to explain zebra-structured type IV emissions. In this model, the basic generation mechanism is identical with that proposed by Winglee and Dulk: mode conversion of Z-mode waves generated by the cyclotron maser mechanism under the condition fuh = Nfce, with N an integer; however, we propose a twist on this model whereby the zebra bursts do not arise from multiple N-values. Rather, the presence of localized density irregularities within the type IV source region leads to trapping of the upper hybrid Z-mode waves in density enhancements, which results in a discrete spectrum of upper hybrid modes with nearly constant frequency spacing. The number m of quasi-harmonics is limited by the trapping (quantization) conditions. The problem is described by an equivalent Schrödinger equation for the trapped mode, which is solved for an (idealized) cylindrical square density irregularity. In this model, the eigenfrequency spacing matches the observed type IV frequency spacings for less than 10% density enhancements with individual scale sizes of 30-1000 thermal electron gyroradii, corresponding to 1-100 m scales in coronal loops. To produce the observed emitted power for a reasonable (\u3c1%) efficiency requires a large number of such individual microscopic sources occurring over a portion of a magnetic type IV loop at a restricted altitude within which the magnetic field and density are approximately constant. The loop plasma in the zebra emission source is thus highly turbulent in the sense that it contains a large number of density fluctuations. In this case transition radiation can effectively contribute to the radiation background and may also provide the wave power required in the upper hybrid range for generating zebra emissions

Strategies to Mitigate the Effects of Soil Physical Disturbances Caused by Forest Machinery: a Comprehensive Review

Purpose of Review: Ground-based mechanized forest operations can cause severe soil disturbances that are often long lasting and detrimental to the health of forested ecosystems. To reduce these soil disturbances, focus is being increasingly directed at identifying and using appropriate mitigation techniques. This systematic review considered 104 scientific articles and reported the main findings according to four core themes: terrain-related factors, operational planning, machine modifications, and types of amendments used to mitigate machine-induced soil impacts. Recent Findings: For terrain-related factors, most severe disturbances occur on machine operating trails exceeding 20% slope and that soil bulk density and rut depth show greater increases in fine-textured soils. When considering operational planning, trafficability maps proved to be helpful in reducing the frequency and magnitude of soil damages as well as the length of trails needed within harvest sites, especially if they are regularly updated with weather information. Machine modifications, through high flotation tires, use of extra bogie axle, lower inflation pressure, and use of steel flexibles tracks, are highly researched topics because of the considerable upside in terms of machine ground pressure distribution and increased traction. Two main types of amendments emerged to mitigate soil disturbances: brush mats and mulch cover. Brush mats created from harvesting debris can spread the load of a machine to a greater area thereby lowering peak loads transferred to the soil. Brush mats of 15–20 kg m−2 are being recommended for adequate soil protection from harvesting operations. Summary: To conclude, we outline recommendations and strategies on the use of soil mitigation techniques within cut-to-length forest operations. New research opportunities are also identified and discussed. Considering single factors causing machine-induced soil disturbances remains important but there is a pressing need for having a multi-disciplinary approach to tackle the complex problems associated with machine/soil/plant interactions

Integrable Supersymmetry Breaking Perturbations of N=1,2 Superconformal Minimal Models

We display a new integrable perturbation for both N=1 and N=2 superconformal minimal models. These perturbations break supersymmetry explicitly. Their existence was expected on the basis of the classification of integrable perturbations of conformal field theories in terms of distinct classical KdV type hierarchies sharing a common second Hamiltonian structure.Comment: 10 pages (harvmac), LAVAL PHY-20-9
