    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

    Full text link
    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

    Full text link
    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 p4p \leq 4. 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

    Full text link
    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 NN dilaton coupled spinors.Comment: LaTeX file 28 pages and two eps files, few misprints are correcte

    Brane-anti-brane Democracy

    Full text link
    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

    Full text link
    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

    Full text link
    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

    Get PDF
    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
