The Effects of Marriage Equality in Massachusetts: A survey of the experiences and impact of marriage on same-sex couples

May 17th, 2009 marks the 5th year of marriage equality in the state of Massachusetts. To mark this anniversary, the Massachusetts Department of Public Health conducted the largest survey to date of married same-sex couples, the Health and Marriage Equality in Massachusetts (HMEM) survey. During the past year, four other states have extended marriage to same-sex couples and several other states are considering marriage legislation. The HMEM data allows us to address important questions that arise as other states consider whether to extend marriage to same-sex couples. The data provides answers to several key questions: Who is getting married? Why are same-sex couples getting married? What impact has marriage had on same-sex relationships? And, what impact has marriage had on the children of same-sex couples

The Fiscal Impact of Extending Federal Benefits to Same-Sex Domestic Partners

This report finds that offering health and other benefits to the same-sex partners of federal employees would add $41 million to the federal budget in the first year of coverage. Over ten years the report predicts the budgetary cost will be$675 million, a small percentage of the federal budget. The report also takes into account the added federal income taxes that will be paid by federal employees if they sign a partner up for health insurance. It estimates the cost of including partners in retirement benefits, work injury and death compensation, and travel and relocation expenses. Many benefits offered to federal employees, such as life insurance and family and medical leave, can be offered to domestic partners at no additional cost to the federal government

Explicit minimal Scherk saddle towers of arbitrary even genera in R3\R^3

Starting from works by Scherk (1835) and by Enneper-Weierstra\ss \ (1863), new minimal surfaces with Scherk ends were found only in 1988 by Karcher (see \cite{Karcher1,Karcher}). In the singly periodic case, Karcher's examples of positive genera had been unique until Traizet obtained new ones in 1996 (see \cite{Traizet}). However, Traizet's construction is implicit and excludes {\it towers}, namely the desingularisation of more than two concurrent planes. Then, new explicit towers were found only in 2006 by Martin and Ramos Batista (see \cite{Martin}), all of them with genus one. For genus two, the first such towers were constructed in 2010 (see \cite{Valerio2}). Back to 2009, implicit towers of arbitrary genera were found in \cite{HMM}. In our present work we obtain {\it explicit} minimal Scherk saddle towers, for any given genus $2k$, $k\ge3$

Magnetic order in Ce0.95Nd0.05CoIn5: the Q-phase at zero magnetic field

We report neutron scattering experiment results revealing the nature of the magnetic order occurring in the heavy fermion superconductor Ce0.95Nd0.05CoIn5, a case for which an antiferromagnetic state is stabilized at a temperature below the superconducting transition one. We evidence an incommensurate order and its propagation vector is found to be identical to that of the magnetic field induced antiferromagnetic order occurring in the stoichiometric superconductor CeCoIn5, the so-called Q-phase. The commonality between these two cases suggests that superconductivity is a requirement for the formation of this kind of magnetic order and the proposed mechanism is the enhancement of nesting condition by d-wave order parameter with nodes in the nesting area.Comment: submitted to Phys.

WISE morphological study of Wolf-Rayet nebulae

We present a morphological study of nebulae around Wolf-Rayet (WR) stars using archival narrow-band optical and Wide-field Infrared Survey Explorer (WISE) infrared images. The comparison among WISE images in different bands and optical images proves to be a very efficient procedure to identify the nebular emission from WR nebulae, and to disentangle it from that of the ISM material along the line of sight. In particular, WR nebulae are clearly detected in the WISE W4 band at 22 $\mu$m. Analysis of available mid-IR Spitzer spectra shows that the emission in this band is dominated by thermal emission from dust spatially coincident with the thin nebular shell or most likely with the leading edge of the nebula. The WR nebulae in our sample present different morphologies that we classified into well defined WR bubbles (bubble ${\cal B}$-type nebulae), clumpy and/or disrupted shells (clumpy/disrupted ${\cal C}$-type nebulae), and material mixed with the diffuse medium (mixed ${\cal M}$-type nebulae). The variety of morphologies presented by WR nebulae shows a loose correlation with the central star spectral type, implying that the nebular and stellar evolutions are not simple and may proceed according to different sequences and time-lapses. We report the discovery of an obscured shell around WR35 only detected in the infrared.Comment: 11 pages, 6 figures, plus 23 appendix figures; to appear in Astronomy and Astrophysic

Comportamento de quatro gramineas forrageiras nos cerrados do centro sul do Piaui.

Quatro gramineas, Brachiaria decumbens cv. Australiana, B. humidicola,Andropogon gayanus cv. Planaltina (capim andropogon) e Melinis minutiflora (capim gordura) foram avaliadas sob pastejo, em Regeneracao, PI,no periodo de 1984 a 1986. O solo da area experimental e um Latossolo Amarelo Distrofico, A moderado, Alico, textura media, fase cerrado. O delineamento foi o de blocos casualizados com quatro repeticoes. Foram estudados a cobertura do solo, altura das plantas, disponibilidade de forragens e teor de proteina bruta. As parcelas foram pastejadas por bovinos na lotacao de um animal/ha, na estacao das chuvas e 0,7 animal/ha na estacao seca. O capim gordura apresentou inicialmente alta cobertura do solo, mas foi reduzindo-se gradativamente com os pastejos sucessivos. A B. decubens e a B. humidicola permaneceram com altos indices de cobertura do solo, durante todo o periodo experimental. A partir dos 90 dias apos a semeadura, o capim andropogon foi a graminea que apresentou maior crescimento e disponibilidade de forragem, tanto na estacao das chuvas, como na seca. Todas as gramineas tiveram teor de proteina bruta da materia seca superior a 7%, havendo, porem, uma reducao no teor desse nutriente do primeiro para o segundo ano.bitstream/item/98438/1/BOL120001.pd
