Testimony Submitted to the United States Senate Committee on the Judiciary: The Uniting American Families Act, Addressing Inequality in Federal Immigration Law

A large body of research has shown that same-sex "unmarried partners" identified in the U.S. Census are primarily composed of lesbian and gay couples. The Census includes questions about citizenship status and country of origin and offers valuable information about same-sex couples who may be affected by UAFA. A 2005 report entitled "Bi-national Same-sex Unmarried Partners in Census 2000: A Demographic Portrait" provides important information about the size and demographic characteristics of bi-national same-sex couples where one partner is a U.S. citizen and the other is not. This testimony summarizes the key findings from that report

Bi-National Same-Sex Unmarried Partners In Census 2000: A Demographic Portrait

While current United States immigration policy is based primarily on family reunification, it does not provide any rights for unmarried partners of citizens. In order to inform current legislative debates about expanding the policy of family reunification to include same-sex couples, this report provides a demographic and geographic portrait of bi-national same-sex "unmarried partners" from Census 2000.Key findings of this report include:Approximately 35,820 of the 594,391 same-sex unmarried partner couples (6%) counted in Census 2000 are bi-national couples.A larger percentage of same-sex couples (6%) than different-sex unmarried (5.2%) or married (4.6%) couples are bi-national. If the Uniting American Families Act were to pass and same-sex couples behaved as their married counterparts, then approximately 8,500 same-sex couples would likely seek immigration rights for the non-citizen partner.Mexico is the home country for 30% (10,766) of the non-citizens in same-sex bi-national couples, compared with 38% of all non-citizens in the United States. Canada, the second highest country of origin, is home to 6% (2,159) of the non-citizen partners in same-sex bi-national couples, followed by El Salvador, Germany, and the Philippines.Thirty-six percent of bi-national same-sex couples are comprised of a foreign born non-citizen and a foreign born citizen. The non-citizen and citizen in 82% of these couples share the same country of origin. In short, over 30% of all bi-national same-sex couples in the U.S. are comprised of partners who were both born in the same foreign country. (Fourteen percent of all bi-national same-sex couples in the U.S. are comprised of partners who were both born in Mexico.)California ranks first in the total number of same-sex bi-national couples. Nearly 30% of same-sex bi-national couples in the United States, more than 10,000 such couples, live in California.In 79% of bi-national same-sex couples, the non-citizen partner comes from a country that does not provide immigration rights to unmarried couples. For these couples, neither partner lives in a county that will allow the other partner to immigrate based on their relationship.Among bi-national couples, more than a third of same-sex male couples and 58% of female same-sex couples report having children under age 18 in the home.Children under age 18 being raised by bi-national same-sex couples are less likely to be citizens than children being raised by bi-national married couples. Ninety percent of children of bi-national married couples are citizens, compared with 83% of bi-national male-male couples and 87% of bi-national female-female couples.Same-sex bi-national couples are more likely to have been together at least five years (28% of male couples and 30% of female couples) than their different-sex unmarried counterparts (17%), but less likely to have been together five years than bi-national married couples (41%)

Same-Sex Couples and Immigration in the United States

This report uses Census Bureau data to provide a portrait of same-sex couples affected by United States immigration policy. Using data from the American Community Survey (ACS) it presents demographic profiles of three different types of same-sex couples: binational couples in which one partner is a U.S. citizen and one is not; dual non-citizen couples; and couples that include a naturalized U.S. citizen. Binational couples and non-citizen couples in which only one partner is a permanent resident would gain protections and rights if U.S. immigration law were changed to treat same-sex couples as their different-sex counterparts are treated. As of 2010, nearly 79,200 same-sex couples living in the United States include at least one partner who is currently not a U.S citizen or was naturalized as a citizen. Of the nearly 650,000 same-sex couples in the US: 4.4% or 28,574 are binational couples (one partner is a U.S. citizen and one is not)1.8% or 11,442 are dual non-citizen couples6.1% or 39,176 are dual citizen couples with at least one naturalized partne

Transverse vibration and buckling of a cantilevered beam with tip body under constant axial base acceleration

The planar transverse bending behavior of a uniform cantilevered beam with rigid tip body subject to constant axial base acceleration was analyzed. The beam is inextensible and capable of small elastic transverse bending deformations only. Two classes of tip bodies are recognized: (1) mass centers located along the beam tip tangent line; and (2) mass centers with arbitrary offset towards the beam attachment point. The steady state response is studied for the beam end condition cases: free, tip mass, tip body with restricted mass center offset, and tip body with arbitrary mass center offset. The first three cases constitute classical Euler buckling problems, and the characteristic equation for the critical loads/accelerations are determined. For the last case a unique steady state solution exists. The free vibration response is examined for the two classes of tip body. The characteristic equation, eigenfunctions and their orthogonality properties are obtained for the case of restricted mass center offset. The vibration problem is nonhomogeneous for the case of arbitrary mass center offset. The exact solution is obtained as a sum of the steady state solution and a superposition of simple harmonic motions

Planar dynamics of a uniform beam with rigid bodies affixed to the ends

The planar dynamics of a uniform elastic beam subject to a variety of geometric and natural boundary conditions and external excitations were analyzed. The beams are inextensible and capable of small transverse bending deformations only. Classical beam vibration eigenvalue problems for a cantilever with tip mass, a cantilever with tip body and an unconstrained beam with rigid bodies at each are examined. The characteristic equations, eigenfunctions and orthogonality relations for each are derived. The forced vibration of a cantilever with tip body subject to base acceleration is analyzed. The exact solution of the governing nonhomogeneous partial differential equation with time dependent boundary conditions is presented and compared with a Rayleigh-Ritz approximate solution. The arbitrary planar motion of an elastic beam with rigid bodies at the ends is addressed. Equations of motion are derived for two modal expansions of the beam deflection. The motion equations are cast in a first order form suitable for numerical integration. Selected FORTRAN programs are provided

On Dimensional Extension of Supersymmetry: From Worldlines to Worldsheets

There exist myriads of off-shell worldline supermultiplets for (N{\leq}32)-extended supersymmetry in which every supercharge maps a component field to precisely one other component field or its derivative. A subset of these extends to off-shell worldsheet (p,q)-supersymmetry and is characterized by the twin theorems 2.1 and 2.2 in this note. The evasion of the obstruction defined in these theorems is conjectured to be sufficient for a worldline supermultiplet to extend to worldsheet supersymmetry; it is also a necessary filter for dimensional extension to higher-dimensional spacetime. We show explicitly how to "re-engineer" an Adinkra---if permitted by the twin theorems 2.1 and 2.2---so as to depict an off-shell supermultiplet of worldsheet (p,q)-supersymmetry.Comment: LaTeX 3 times, added reference, minor edits and typo correctio

Non-Abelian Tensors with Consistent Interactions

We present a systematic method for constructing consistent interactions for a tensor field of an arbitrary rank in the adjoint representation of an arbitrary gauge group in any space-time dimensions. This method is inspired by the dimensional reduction of Scherk-Schwarz, modifying field strengths with certain Chern-Simons forms, together with modified tensorial gauge transformations. In order to define a consistent field strength of a r-rank tensor B_{\mu_1...\mu_r}^I in the adjoint representation, we need the multiplet (B_{\mu_1...\mu_r}^I, B_{\mu_1...\mu_{r-1}}^{I J}, ..., B_\mu^{I_1...I_r}, B^{I_1... I_{r+1}}). The usual problem of consistency of the tensor field equations is circumvented in this formulation.Comment: 15 pages, no figure

A Computer Algorithm For Engineering Off-Shell Multiplets With Four Supercharges On The World Sheet

We present an adinkra-based computer algorithm implemented in a Mathematica code and use it in a limited demonstration of how to engineer off-shell, arbitrary N-extended world-sheet supermultiplets. Using one of the outputs from this algorithm, we present evidence for the unexpected discovery of a previously unknown 8 - 8 representation of N = 2 world sheet supersymmetry. As well, we uncover a menagerie of (p, q) = (3, 1) world sheet supermultiplets.Comment: 52 pages, 64 figures, LaTeX twice, added note in proof, addition of comments about gauge invariance for 4D vector & tensor supermultiplet

Control of complex networks requires both structure and dynamics

The study of network structure has uncovered signatures of the organization of complex systems. However, there is also a need to understand how to control them; for example, identifying strategies to revert a diseased cell to a healthy state, or a mature cell to a pluripotent state. Two recent methodologies suggest that the controllability of complex systems can be predicted solely from the graph of interactions between variables, without considering their dynamics: structural controllability and minimum dominating sets. We demonstrate that such structure-only methods fail to characterize controllability when dynamics are introduced. We study Boolean network ensembles of network motifs as well as three models of biochemical regulation: the segment polarity network in Drosophila melanogaster, the cell cycle of budding yeast Saccharomyces cerevisiae, and the floral organ arrangement in Arabidopsis thaliana. We demonstrate that structure-only methods both undershoot and overshoot the number and which sets of critical variables best control the dynamics of these models, highlighting the importance of the actual system dynamics in determining control. Our analysis further shows that the logic of automata transition functions, namely how canalizing they are, plays an important role in the extent to which structure predicts dynamics.Comment: 15 pages, 6 figure
