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
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?
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
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,

Courts, care proceedings and outcomes uncertainty: the challenges of achieving and assessing ‘good outcomes’ for children after child protection proceedings
The professed aim of any social welfare or legal intervention in family life is often to bring about ‘better outcomes for the children’. But there is considerable ambiguity about ‘outcomes’, and the term is far too often used in far too simplistic a way. This paper draws on empirical research into the outcomes of care proceedings for a randomly selected sample of 616 children in England and Wales, about half starting proceedings in 2009-10, and the others in 2014-15. The paper considers the challenges of achieving and assessing ‘good outcomes’ for the children. Outcomes are complex and fluid for all children, whatever the court order. One has to assess the progress of the children in the light of their individual needs and in the context of ‘normal’ child development; and in terms of the legal provisions and policy expectations. A core paradox is that some of the most uncertain outcomes are for children who remain with or return to their parents; yet law and policy require that first consideration is given to this option. Greater transparency about the uncertainty of outcomes is a necessary step towards better understanding the risks and potential benefits of care proceedings
