Salaries of Members of Congress: Congressional Votes, 1990-2014
The automatic annual adjustment for Members of Congress is determined by a formula using a component of the Employment Cost Index (ECI), which measures rate of change in private sector pay. The adjustment automatically takes effect unless (1) Congress statutorily prohibits the adjustment; (2) Congress statutorily revises the adjustment; or (3) the annual base pay adjustment of General Schedule (GS) federal employees is established at a rate less than the scheduled increase for Members, in which case the percentage adjustment for Member pay is automatically lowered to match the percentage adjustment in GS base pay. In the past, Member pay has been frozen statutorily in two ways: (1) directly, through legislation that freezes salaries for Members but not other federal employees, and (2) indirectly, through broader pay freeze legislation that covers Members and other specified categories of federal employees. Under the formula, Members may not receive an annual pay adjustment greater than 5%.
This adjustment formula was established by the Ethics Reform Act of 1989. Votes on the annual adjustments since the implementation of this act are contained in this report

Salaries of Members of Congress: A List of Payable Rates and Effective Dates, 1789-2008
Congress is required by Article I, Section 6, of the Constitution to determine its own pay. Prior to 1969, Congress did so by enacting stand-alone legislation. From 1789 through 1968, Congress raised its pay 22 times using this procedure. Congressional salaries initially were 30,000. Stand-alone legislation may still be used to raise Member pay, as it was most recently in 1982, 1983, 1989, and 1991, but two other methods — including an automatic annual adjustment procedure and a commission process — are now also available.
Under the annual adjustment procedure, Members were scheduled to receive a 2.7% increase in January 2008. The increase was revised to 2.5%, resulting in a salary in 2008 of 165,200
Genus Two Partition Functions and Renyi Entropies of Large c CFTs
We compute genus two partition functions in two dimensional conformal field
theories at large central charge, focusing on surfaces that give the third
Renyi entropy of two intervals. We compute this for generalized free theories
and for symmetric orbifolds, and compare it to the result in pure gravity. We
find a new phase transition if the theory contains a light operator of
dimension . This means in particular that unlike the second
Renyi entropy, the third one is no longer universal.Comment: 28 pages + Appendice
Orbital Circularization of a Planet Accreting Disk Gas: Formation of Distant Jupiters in Circular Orbits based on Core Accretion Model
Recently, gas giant planets in nearly circular orbits with large semimajor
axes ( 30--1000AU) have been detected by direct imaging. We have
investigated orbital evolution in a formation scenario for such planets, based
on core accretion model: i) Icy cores accrete from planetesimals at
30AU, ii) they are scattered outward by an emerging nearby gas giant to acquire
highly eccentric orbits, and iii) their orbits are circularized through
accretion of disk gas in outer regions, where they spend most of time. We
analytically derived equations to describe the orbital circularization through
the gas accretion. Numerical integrations of these equations show that the
eccentricity decreases by a factor of more than 5 during the planetary mass
increases by a factor of 10. Because runaway gas accretion increases planetary
mass by 10--300, the orbits are sufficiently circularized. On the other
hand, is reduced at most only by a factor of 2, leaving the planets in
outer regions. If the relative velocity damping by shock is considered, the
circularization is slowed down, but still efficient enough. Therefore, this
scenario potentially accounts for the formation of observed distant jupiters in
nearly circular orbits. If the apocenter distances of the scattered cores are
larger than the disk sizes, their shrink to a quarter of the disk sizes;
the -distribution of distant giants could reflect outer edges of the disks
in a similar way that those of hot jupiters may reflect inner edges.Comment: 28 pages, 13 figures, accepted for publication in Ap
Twist-nontwist correlators in M^N/S_N orbifold CFTs
We consider general 2D orbifold CFTs of the form M^N/S_N, with M a target
space manifold and S_N the symmetric group, and generalize the Lunin-Mathur
covering space technique in two ways. First, we consider excitations of twist
operators by modes of fields that are not twisted by that operator, and show
how to account for these excitations when computing correlation functions in
the covering space. Second, we consider non-twist sector operators and show how
to include the effects of these insertions in the covering space. We work two
examples, one using a simple bosonic CFT, and one using the D1-D5 CFT at the
orbifold point. We show that the resulting correlators have the correct form
for a 2D CFT.Comment: 30 pages, 1 figure, additional reference adde
Operator mixing for string states in the D1-D5 CFT near the orbifold point
In the context of the fuzzball programme, we investigate deforming the
microscopic string description of the D1-D5 system on T^4xS^1 away from the
orbifold point. Using conformal perturbation theory and a generalization of
Lunin-Mathur symmetric orbifold technology for computing twist-nontwist
correlators developed in a companion work, we initiate a program to compute the
anomalous dimensions of low-lying string states in the D1-D5 superconformal
field theory. Our method entails finding four-point functions involving a
string operator O of interest and the deformation operator, taking coincidence
limits to identify which other operators mix with O, subtracting the identified
conformal family to isolate other contributions to the four-point function,
finding the mixing coefficients, and iterating. For the lowest-lying string
modes, this procedure should truncate in a finite number of steps. We check our
method by showing how the operator dual to the dilaton does not participate in
mixing that would change its conformal dimension, as expected. Next we complete
the first stage of the iteration procedure for a low-lying string state of the
form \partial X \partial X \bar\partial X \bar\partial X and find its mixing
coefficient. Our main qualitative result is evidence of operator mixing at
first order in the deformation parameter, which means that the string state
acquires an anomalous dimension. After diagonalization this will mean that
anomalous dimensions of some string states in the D1-D5 SCFT must decrease away
from the orbifold point while others increase.Comment: 43 pages, added references and a commen
Bosonization, cocycles, and the D1-D5 CFT on the covering surface
We consider the D1-D5 CFT near the orbifold point, specifically the
computation of correlators involving twist sector fields using covering surface
techniques. As is well known, certain twists introduce spin fields on the
cover. Here we consider the bosonization of fermions to facilitate computations
involving the spin fields. We find a set of cocycle operators that satisfy
constraints coming from various symmetries, including the
R-symmetry. Using these cocycles, we consider the
correlator of four spin fields on the cover, and show that it is invariant
under all of the symmetries of the theory. We consider the mutual
locality of operators, and compute several three-point functions. These
computations lead us to a notion of radial ordering on the cover that is
inherited from the original computation before lifting. Further, we note that
summing over orbifold images sets certain branch-cut ambiguous correlators to
zero.Comment: 29 pages, 1 figur

Women in the United States Congress: Historical Overview, Tables, and Discussion
A record 102 women currently serve in the 113th Congress: 82 in the House (63 Democrats and 19 Republicans) and 20 in the Senate (16 Democrats and 4 Republicans). One hundred one women were initially sworn in to the 113th Congress—1 female Republican House Member has since resigned, and 2 Democratic House Members have been elected. This is higher than the previous record number of 95 women who were initially elected to the 111th Congress. The first woman elected to Congress was Representative Jeannette Rankin (R- MT, 1917-1919, 1941-1943). The first woman to serve in the Senate was Rebecca Latimer Felton (D-GA). She was appointed in 1922 and served for only one day. Hattie Caraway (D-AR, 1931-1945) was the first Senator to succeed her husband and the first woman elected to a six-year Senate term. A total of 298 women have served in Congress, 194 Democrats and 104 Republicans. Of these women, 254 (165 Democrats, 89 Republicans) have served only in the House of Representatives; 34 (21 Democrats, 13 Republicans) have served only in the Senate; and 10 (8 Democrats, 2 Republicans) have served in both houses. These figures include 4 non-voting Delegates, 1 each from Guam, Hawaii, the District of Columbia, and the U.S. Virgin Islands. A total of 33 African American women have served in Congress (1 in the Senate, 32 in the House), including 17 serving in the 113th Congress. Ten Hispanic women have been elected to the House; nine serve in the 113th Congress. Nine Asian Pacific American women have served in Congress (8 in the House, 1 in both the House and Senate), including seven in the 113th Congress. Nineteen women in the House, and 10 women in the Senate, have chaired committees. In the 113th Congress, 1 woman chairs a House committee, and 5 women chair Senate committees, with 1 female Senator chairing two committees.
This report includes a discussion of the impact of women in Congress as well as historical information, including the number and percentage of women in Congress over time, means of entry to Congress, comparisons to international and state legislatures, records for tenure, firsts for women in Congress, women in leadership, and African American and Asian Pacific American women in Congress. The report may reflect data at the beginning or end of each Congress, or changes during a Congress. See the notes throughout the report for information on the currency of the data
3D MHD Simulations of Planet Migration in Turbulent Stratified Disks
We performed 3D MHD simulations of planet migration in stratified disks using
the Godunov code PLUTO, where the disk is turbulent due to the
magnetorotational instability. We study the migration for planets with
different planet-star mass ratios . In agreement with previous
studies, for the low-mass planet cases ( and ),
migration is dominated by random fluctuations in the torque. For a Jupiter-mass
planet for , we find a reduction of
the magnetic stress inside the orbit of the planet and around the gap region.
After an initial stage where the torque on the planet is positive, it reverses
and we recover migration rates similar to those found in disks where the
turbulent viscosity is modelled by an viscosity. For the
intermediate-mass planets ( and ) we
find a new and so far unexpected behavior. In some cases they experience
sustained and systematic outwards migration for the entire duration of the
simulation. For this case, the horseshoe region is resolved and torques coming
from the corotation region can remain unsaturated due to the stresses in the
disk. These stresses are generated directly by the magnetic field. The
magnitude of the horseshoe drag can overcome the negative Lindblad contribution
when the local surface density profile is flat or increasing outwards, which we
see in certain locations in our simulations due to the presence of a zonal
flow. The intermediate-mass planet is migrating radially outwards in locations
where there is a positive gradient of a pressure bump (zonal flow).Comment: Accepted for publication in Ap
