Locking Up Family Values: The Detention of Immigrant Families
On any given day the U.S. government has the capacity to detain over 600 men, women and children apprehended as family units along the U.S. border and within the interior of the country. The detention of families expanded dramatically in 2006 with the opening of the new 512-bed T. Don Hutto Residential Center. Although Hutto has become the centerpiece of a major expansion of immigration detention in America, it builds on and further institutionalizes many of the practices established at the smaller Berks Family Shelter Care Facility in Leesport, PA, where U.S. Immigration and Customs Enforcement (ICE) has detained a small number of families since 2001. The recent increase in family detention represents a major shift in the U.S. government's treatment of families in immigration proceedings. Prior to the opening of Hutto, the majority of families were either released together from detention or separated from each other and detained individually. Children were placed in the custody of the Office of Refugee Resettlement (ORR) Division for Unaccompanied Children's Services, and parents were detained in adult facilities. Congress discovered this and took immediate action to rectify it, in keeping with America's tradition of promoting family values. It directed ICE to stop separating families and either to place them in alternative programs or to detain them together in nonpenal, homelike settings. Such Congressional directives were intended to preserve and protect the role of the family as the fundamental unit in our society. However, ICE chose to develop a penal detention model that is fundamentally anti-family and un-American. Lutheran Immigration and Refugee Service and the Women's Commission for Refugee Women and Children felt it vital to examine the implications of this expanding penal approach to family detention in order to inform the development of policy and practice that serves the best interests of children and families. To that end we visited both the T. Don Hutto Residential Center and the Berks Family Shelter Care Facility and talked with detained families as well as former detainees. What we found was disturbing:- Hutto is a former criminal facility that still looks and feels like a prison, complete with razor wire and prison cells.- Some families with young children have been detained in these facilities for up to two years.- The majority of children detained in these facilities appeared to be under the age of 12.- At night, children as young as six were separated from their parents.- Separation and threats of separation were used as disciplinary tools.- People in detention displayed widespread and obvious psychological trauma. Every woman we spoke with in a private setting cried.- At Hutto pregnant women received inadequate prenatal care.- Children detained at Hutto received one hour of schooling per day.- Families in Hutto received no more than twenty minutes to go through the cafeteria line and feed their children and themselves. Children were frequently sick from the food and losing weight.- Families in Hutto received extremely limited indoor and outdoor recreation time and children did not have any soft toys.Yet not everything we saw reflected a failure of the system. At the Berks facility:- The educational system was appropriate to children's developmental needs.- Families were permitted to participate in field trips.- Children were able to participate in arts and crafts activities.- Families enjoyed ample outdoor recreation time in an open, grassy area. But despite these few positives, the system of family detention is overwhelmingly inappropriate for families.- Both settings strip parents of their role as arbiter and architect of the family unit.- Both facilities place families in settings modeled on the criminal justice system.- There are no licensing requirements for family detention facilities because there is no precedent for family detention in the United States.- There are no standards for family detention, but both facilities violated various aspects of existing standards for the treatment of unaccompanied children and adults in immigration proceedings.Neither facility provides an acceptable model for addressing the reality of the presence of families in our immigration system. Although there is precedent in the adult detention system for the use of alternatives to detention and other pre-hearing release systems,4 ICE has unfortunately made no effort to expand these programs to include families. Based upon these findings, we recommend the following systemic changes to the U.S. government's treatment of families in immigration proceedings:- Discontinue the detention of families in prison-like institutions.- Parole asylum seekers in accordance with international standards and DHS's own policy guidelines- Expand parole and release options for apprehended families.- Implement alternatives to detention for families not eligible for parole or release.- House families not eligible for parole or release in appropriate, nonpenal, homelike facilities.- Expand public-private partnerships to provide legal information and pro bono legal access for all detained families, and to implement alternative programs
The U.S. Response to Human Trafficking: An Unbalanced Approach
The United States' anti-trafficking efforts formally began with the passage of the Trafficking Victims Protection Act (TVPA) of 2000. Since then, the U.S. Government has poured billions of dollars into prevention efforts overseas and prosecution and protection efforts at home. In many ways it provides a model to other countries that are trying to address human trafficking. This report is focused on the United States' efforts to protect trafficked persons found in the United States. Under the TVPA, protections, services and benefits are only offered to trafficked persons who are witnesses assisting law enforcement. This system presents its own challenges in accessing benefits and services, particularly due to law enforcement's anipulation of the system. This is not a case of unforeseen implementation struggles that can be fixed. Instead, at issue is the entire conceptual framework of trafficking as a law enforcement issue and only a law enforcement issue. The results of six years of this approach are becoming startlingly clear -- few trafficked persons coming forward to work with law enforcement. Those who are discovered by law enforcement but refuse or are unable to recount their experiences are not offered any protections and are instead deported. This is an acute problem in particular for trafficked children. The Women's Commission for Refugee Women and Children (Women's Commission) believes that this is an unbalanced approach and that the consequences are grave. While prosecuting traffickers is a just and necessary goal, it should not be accomplished at the expense of the trafficked person. Both objectives can be achieved successfully by adopting a rights-based approach, which entails providing protections to all trafficked persons. It is increasingly acknowledged and recognized even among law enforcement officials that a trafficked person who receives assistance is more likely, willing and able to work with law enforcement. Another issue throwing trafficking protections off balance is the United States' policy which focuses government trafficking efforts on eradicating prostitution, which it conflates with sex trafficking. Efforts at addressing contributing factors to trafficking are laudable but should not be pursued to the exclusion of other efforts. There is a need for immigration and labor reform that would yield dramatic results in protections for trafficked and exploited persons in the informal economy
Crossing the cosmological constant line in a dilatonic brane-world model with and without curvature corrections
We construct a new brane-world model composed of a bulk -with a dilatonic
field-, plus a brane -with brane tension coupled to the dilaton-, cold dark
matter and an induced gravity term. It is possible to show that depending on
the nature of the coupling between the brane tension and the dilaton this model
can describe the late-time acceleration of the brane expansion (for the normal
branch) as it moves within the bulk. The acceleration is produced together with
a mimicry of the crossing of the cosmological constant line (w=-1) on the
brane, although this crossing of the phantom divide is obtained without
invoking any phantom matter neither on the brane nor in the bulk. The role of
dark energy is played by the brane tension, which reaches a maximum positive
value along the cosmological expansion of the brane. It is precisely at that
maximum that the crossing of the phantom divide takes place. We also show that
these results remain valid when the induced gravity term on the brane is
switched off.Comment: 12 pages, 2 figures, RevTeX
Cosmology and two-body problem of D-branes
In this paper, we investigate the dynamics and the evolution of the scale
factor of a probe Dp-brane which move in the background of source Dp-branes.
Action of the probe brane is described by the Born-Infeld action and the
interaction with the background R-R field. When the probe brane moves away from
the source branes, it expands by power law, whose index depends on the
dimension of the brane. If the energy density of the gauge field on the brane
is subdominant, the expansion is decelerating irrespective of the dimension of
the brane. On the other hand, when the probe brane is a Nambu-Goto brane, the
energy density of the gauge field can be dominant, in which case accelerating
expansion occurs for . The accelerating expansion stops when the
brane has expanded sufficiently so that the energy density of the gauge field
become subdominant.Comment: 6 pages, 7 figures, reference added, accepted for publication in PR
(Non)-singular brane-world cosmology induced by quantum effects in d5 dilatonic gravity
5d dilatonic gravity (bosonic sector of gauged supergravity) with non-trivial
bulk potential and with surface terms (boundary cosmological constant and trace
anomaly induced effective action for brane quantum matter) is considered. For
constant bulk potential and maximally SUSY Yang-Mills theory (CFT living on the
brane) the inflationary brane-world is constructed. The bulk is singular
asymptotically AdS space with non-constant dilaton and dilatonic de Sitter or
hyperbolic brane is induced by quantum matter effects. At the same time,
dilaton on the brane is determined dynamically. This all is natural realization
of warped compactification in AdS/CFT correspondence. For fine-tuned toy
example of non-constant bulk potential we found the non-singular dilatonic
brane-world where bulk again represents asymptotically AdS space and de Sitter
brane (inflationary phase of observable Universe) is induced exclusively by
quantum effects. The radius of the brane and dilaton are determined
dynamically. The analytically solvable example of exponential bulk potential
leading to singular asymptotically AdS dilatonic bulk space with de Sitter (or
hyperbolic) brane is also presented.In all cases under discussion the gravity
on the brane is trapped via Randall-Sundrum scenario. It is shown that
qualitatively the same types of brane-worlds occur when quantum brane matter is
described by dilaton coupled spinors.Comment: LaTeX file 28 pages and two eps files, few misprints are correcte
Brane-anti-brane Democracy
We suggest a duality invariant formula for the entropy and temperature of
non-extreme black holes in supersymmetric string theory. The entropy is given
in terms of the duality invariant parameter of the deviation from extremality
and 56 SU(8) covariant central charges. It interpolates between the entropies
of Schwarzschild solution and extremal solutions with various amount of
unbroken supersymmetries and therefore serves for classification of black holes
in supersymmetric string theories. We introduce the second auxiliary 56 via
E(7) symmetric constraint. The symmetric and antisymmetric combinations of
these two multiplets are related via moduli to the corresponding two
fundamental representations of E(7): brane and anti-brane "numbers." Using the
CPT as well as C symmetry of the entropy formula and duality one can explain
the mysterious simplicity of the non-extreme black hole area formula in terms
of branes and anti-branes.Comment: LaTeX, 12 pages, no figure
Brane Interaction as the Origin of Inflation
We reanalyze brane inflation with brane-brane interactions at an angle, which
include the special case of brane-anti-brane interaction. If nature is
described by a stringy realization of the brane world scenario today (with
arbitrary compactification), and if some additional branes were present in the
early universe, we find that an inflationary epoch is generically quite
natural, ending with a big bang when the last branes collide. In an interesting
brane inflationary scenario suggested by generic string model-building, we use
the density perturbation observed in the cosmic microwave background and the
coupling unification to find that the string scale is comparable to the GUT
scale.Comment: 28 pages, 8 figures, 2 tables, JHEP forma
D-brane orbiting NS5-branes
We study real time dynamics of a Dp-brane orbiting a stack of NS5-branes. It
is generally known that a BPS D-brane moving in the vicinity of NS5-branes
becomes unstable due to the presence of tachyonic degree of freedom induced on
the D-brane. Indeed, the D-brane necessarily falls into the fivebranes due to
gravitational attraction and eventually collapses into a pressureless fluid.
Such a decay of the D-brane is known to be closely related to the rolling
tachyon problem. In this paper we show that in special cases the decay of
D-brane caused by gravitational attraction can be avoided. Namely for certain
values of energy and angular momentum the D-brane orbits around the fivebranes,
maintaining certain distance from the fivebranes all the time, and the process
of tachyon condensation is suppressed. We show that the tachyonic degree of
freedom induced on such a D-brane really disappears and the brane returns to a
stable D-brane.Comment: 12 pages, latex, added referenc
Free Energies and Probe Actions for Near-horizon D-branes and D1 + D5 System
By working with the free energy for the type II supergravity near-horizon
solution of N coincident non-extremal Dp-branes we study the transitions among
the non-conformal Dp-brane system, the perturbative super Yang-Mills theory and
a certain system associated with M theory. We derive a relation between this
free energy and the action of a Dp-brane probe in the N Dp-brane background.
Constructing the free energy for the five dimensional black hole labeled by the
D1-brane and D5-brane charges we find the similar relation between it and the
action of a D1 or D5 brane probe in the D1 + D5 brane background. These
relations are explained by the massive open strings stretched between the
relevant D-branesComment: 14 pages, LaTeX2e, no figure
