    Public Education in Buffalo and the Region

    The biggest problem facing Buffalo’s public schools is the fact that many students live in poverty, while at the same time being segregated from students from wealthier communities who tend to enjoy better educational opportunities and rates of academic success. Buffalo shares many of the problems of large cities in the United States, largely caused by high concentrations of poverty in urban areas. In 2009, about 59% of students served by urban school districts located in the metropolitan areas of the 50 largest U.S. cities graduated, compared with 77% in nearby suburban communities. In Western New York, all of Buffalo Business First’s highest ranked public high schools except City Honors are located in affluent suburbs: Williamsville, East Aurora, Clarence, Lewiston-Porter, etc. The thirteen lowest ranked high schools are in the City of Buffalo

    Vacant and Abandoned Housing in Buffalo

    Buffalo has the oldest housing stock in the nation, with the largest percentage (67%) of homes built before 1940. In Erie County in 2013 there were 275 cases of elevated lead levels in children. The City of Buffalo has three of five zip codes in state with worst lead poisoning levels and accounts for roughly 95% of county lead cases. As of 2008, 13%-22% of children in the City suffered from asthma. In 2006, the City received 7,460 calls regarding housing violations and 1,612 regarding violations at vacant houses

    A Stereotaxic Atlas of the Brain of the Chick (Gallus domesticus)

    Nine brains taken from chicks two weeks of age were used for the development of this atlas. Each chick was first anesthetized with an intravenous (IV) injection of Chloropent2 (1.8 ml/kg). Chicks were then perfused via the heart with 90 ml physiological saline followed by 90 ml Heidenhain\u27s3 solution. Each head was then positioned in a stereotaxic instrument as described in the previous section and three stainless steel (SS) insect pins (#2) were implanted in each brain at known coordinates. In the case of the brains used to construct the cross- sectional atlas plates, two pins were implanted horizontal to the base of the stereotaxic instrument. Each was inserted into the forebrain and the pins exited either the brainstem or the cerebellum. The third pin was inserted vertical to the base of the stereotaxic instrument. The brains used to construct the sagittal atlas plates had two pins inserted horizontally and one pin inserted vertically to the stereotaxic instrument. The horizontal pins entered the right side of the brain and exited the left side. The brains used for the horizontal plates had two pins inserted vertically and one pin horizontally. The latter entered the forebrain and exited the brainstem

    A compact density condensation around L1551-IRS 5: 2.7mm continuum observations with 4" resolution

    The dark cloud L1551 contains the best known examples of bipolar molecular outflow. Such outflows are assumed to be driven by winds from young stars embedded in a cloud but the mechanism for collimation of the outflows is still in doubt, though it has been much debated. Among the possibilities put forth to date are intrinsically anisotropic stellar winds, isotropic stellar winds collimated by interstellar toroidal shaped clouds on the order of 10(17) cm in size, or circumstellar disks of order 10(15) cm in size. Because the outflow in L1551 as revealed by the Very Large Array (VLA) cm continuum observations is collimated even at the arc second level it seems as though the stellar wind powering the outflow must either be initially anisotropic or be collimated by something very close to the star, such as a circumstellar disk. We have observed L1551 in the continuum at 2.7 mm with the OVRO millimeter-wave interferometer in the winter of 1983-4 and again, more extensively, in 1985-6. The resulting map shows for the first time direct evidence for a density condensation capable of collimating an initially isotropic flow from IRS 5. This map made from data taken in 1985-6 with projected baselines up to 100 m in length (37k lambda). It has been cleaned and reconstructed with a 4'' gaussian beam. It shows a nearly unresolved source with a suggestion of extension at the 3'' level (assuming a gaussian source shape). The integrated flux density in this map is 170 mJy. A composite spectrum of L1551 is presented which shows that the flux at 2.7 mm is due to the thermal radiation from dust that is also seen at shorter wavelengths. Very little of it can be due to the continuation of the nearly flat cm wavelength spectrum which is assumed to be from thermal bremsstrahlung radiation. The map and spectrum provide strong constraints on the size, temperature, and optical depth of the density condensation surrounding IRS 5

    Linear Connections on the Two Parameter Quantum Plane

    Full text link
    We apply a recently proposed definition of a linear connection in non commutative geometry based on the natural bimodule structure of the algebra of differential forms to the case of the two-parameter quantum plane. We find that there exists a non trivial family of linear connections only when the two parameters obeys a specific relation.Comment: 7 pages, Te

    Who is failing abused and neglected children?

    Get PDF
    This is a response to an article by Nigel Speight and Jane Wynne, ‘Is the Children Act failing severely abused and neglected children?’, published in this journal in March 2000.1 Overall, we consider the article to be polemical and inadequately argued. Many of the points made are unsubstantiated and there are errors of fact. Where does evidence based practice go if senior practitioners prefer anecdotes and personal belief to research findings? Restrictions on space preclude an exhaustive reply to all the points Speight and Wynne raise, so we have confined ourselves to addressing those considered most significant

    Gradient discretization of Hybrid Dimensional Darcy Flows in Fractured Porous Media with discontinuous pressures at the matrix fracture interfaces

    Get PDF
    We investigate the discretization of Darcy flow through fractured porous media on general meshes. We consider a hybrid dimensional model, invoking a complex network of planar fractures. The model accounts for matrix-fracture interactions and fractures acting either as drains or as barriers, i.e. we have to deal with pressure discontinuities at matrix-fracture interfaces. The numerical analysis is performed in the general framework of gradient discretizations which is extended to the model under consideration. Two families of schemes namely the Vertex Approximate Gradient scheme (VAG) and the Hybrid Finite Volume scheme (HFV) are detailed and shown to satisfy the gradient scheme framework, which yields, in particular, convergence. Numerical tests confirm the theoretical results. Gradient Discretization; Darcy Flow, Discrete Fracture Networks, Finite Volum

    ESTSS at 20 years: "a phoenix gently rising from a lava flow of European trauma"

    Get PDF
    Roderick J. Ørner, who was President between 1997 and 1999, traces the phoenix-like origins of the European Society for Traumatic Stress Studies (ESTSS) from an informal business meeting called during the 1st European Conference on Traumatic Stress (ECOTS) in 1987 to its emergence into a formally constituted society. He dwells on the challenges of tendering a trauma society within a continent where trauma has been and remains endemic. ESTSS successes are noted along with a number of personal reflections on activities that give rise to concern for the present as well as its future prospects. Denial of survivors' experiences and turning away from survivors' narratives by reframing their experiences to accommodate helpers' theory-driven imperatives are viewed with alarm. Arguments are presented for making human rights, memory, and ethics core elements of a distinctive European psycho traumatology, which will secure current ESTSS viability and future integrity
