Involved, Invisible, Ignored: The Experiences of Lesbian, Gay, Bisexual and Transgender Parents and Their Children in Our Nation's K-12 Schools

Current estimates suggest there are upwards of 7 million lesbian, gay, bisexual and transgender (LGBT) parents with dependent children in the United States, and it is likely that these numbers have been increasing over recent years. Yet little is known about the life experiences of this population of families in general and even less is know about the experiences of these families when interacting with their children's schools.This national study conducted by GLSEN in partnership with the Family Equality Council and COLAGE (Children of Lesbians and Gays Everywhere), examines and highlights the school experiences of LGBT-headed families using results from surveys of LGBT parents of children in K-12 schools and of secondary students who have LGBT parents.The study examines the family-school relationship, including family-school communication, parental involvement in school activities, parent-child discussions about school, parental role in educating school staff about LGBT families and the quality of treatment by school staff and by other members of the school community

Shared Differences: The Experiences of Lesbian, Gay, Bisexual and Transgender Students of Color in Our Nation's Schools

The report documents the school experiences of over 2,000 lesbian, gay, bisexual, and transgender (LGBT) U.S. middle and high school students of color who were African American or Black, Latino/a, Asian or Pacific Islander, Native American, and multiracial

Brownian Motion on a Sphere: Distribution of Solid Angles

We study the diffusion of Brownian particles on the surface of a sphere and compute the distribution of solid angles enclosed by the diffusing particles. This function describes the distribution of geometric phases in two state quantum systems (or polarised light) undergoing random evolution. Our results are also relevant to recent experiments which observe the Brownian motion of molecules on curved surfaces like micelles and biological membranes. Our theoretical analysis agrees well with the results of computer experiments.Comment: 11 pages, two figures, Fig2 in Colour,references update

The effects of a counter-current interstitial flow on a discharging hourglass

This work experimentally investigates the effects of an interstitial fluid on the discharge of granular material within an hourglass. The experiments include observations of the flow patterns, measurements of the discharge rates, and pressure variations for a range of different fluid viscosities, particle densities and diameters, and hourglass geometries. The results are classified into three regimes: (i) granular flows with negligible interstitial fluid effects; (ii) flows affected by the presence of the interstitial fluid; and (iii) a no-flow region in which particles arch across the orifice and do not discharge. Within the fluid-affected region, the flows were visually classified as lubricated and air-coupled flows, oscillatory flows, channeling flows in which the flow preferentially rises along the sidewalls, and fluidized flows in which the upward flow suspends the particles. The discharge rates depends on the Archimedes number, the ratio of the effective hopper diameter to the particle diameter, and hourglass geometry. The hopper-discharge experiments, as well as experiments found in the literature, demonstrate that the presence of the interstitial fluid is important when the nondimensional ratio (N) of the single-particle terminal velocity to the hopper discharge velocity is less than 10. Flow ceased in all experiments in which the particle diameter was greater than 25% of the effective hopper diameter regardless of the interstitial fluid

Polyimide from bis(n-isoprenyl)s of aryl diamides

A process and polyimide product formed by the reaction of a bismaleimide with a bis(amidediene) is disclosed wherein the bis(amidediene) is formed by reacting an excess of an acid chloride with 1,4-N,N'-diisoprenyl 2,3,5,6-tetramethy1 benzene

Predicting real growth using the yield curve

A study using out-of-sample regressions to determine how well the 10-year, 3-month yield spread predicts future real GDP growth. The author finds that although the yield curve is a good predictor over the entire 30-year sample period, it has become much less accurate over the last decade.Forecasting ; Interest rates

Gilt by association: uncovering expected inflation

An argument that U.S. inflation expectations are better measured by comparing U.S. treasury bonds with British "gilts" -- marketable securities linked to a broad index of retail prices -- than by surveys or econometric models.Great Britain ; Bonds - Great Britain

From Statehouse to Schoolhouse: Anti-Bullying Policy Efforts in U.S. States and School Districts

In 2011, 29.5 percent of U.S. public school districts didn't have anti-bullying policies, including many districts in states that require them, according to a report published by GLSEN. In states with such mandates, 26.3 percent of districts didn't have local policies. The report shows the gap that can emerge between the intentions of a law and the effectiveness of its implementation via policy and regulations
