Therapeutic Alliance Among Individuals who Experienced Childhood Interpersonal Trauma: The Role of Cultural Humility, Therapeutic Presence, and Attachment Style

Despite decades of prevention campaigns and research, childhood interpersonal trauma remains a critical mental health problem in the United States with longstanding and harmful negative effects on adult psycho-relational functioning (Dugal, Bigras, Godbout, & Belanger, 2016). In the United States, 678,810 children were found to be victims of childhood abuse in one year (U.S. Department of Health & Human Services, 2013). Estimated prevalence rates of childhood trauma in American adults older than 55 years were 13.5% for verbal abuse, 9.6% for physical abuse and 9.3% for sexual abuse (Bynum et al., 2010). Childhood interpersonal trauma may have a damaging impact on a child’s development (Dodge, 2010; Schury & Kolassa, 2012), and in the long run may lead to high rates of suicidality and low levels of social functioning (Stansfeld et al., 2010). Extended interdisciplinary common factor research has identified the therapeutic alliance as a consistent factor influencing therapeutic outcomes (Flückiger, Del Re, Wampold, Koole & Tschacher, 2016; Symonds & Horvath, 2012). Cultural humility (Hook, Davis, Worthington, & Utsey, 2013; Owen et al., 2014), therapeutic presence (Colosimo & Pos, 2015; Geller & Porges, 2014), and attachment style (Byrd, Patterson, & Turchik, 2010; Marmarosh et al., 2009) have all been found to significantly contribute to the development of the therapeutic alliance. However, these factors have not been investigated together in the context of working with individuals with a history of childhood interpersonal trauma. These variables are of particular importance looking at interpersonal trauma survivors, as healing relationships that provide quietness, safety, presence, protection, and empowerment are integral to their recovery process (Herman, 1992; Levine, 1997). This study investigated the relationships among cultural humility, therapeutic presence, attachment style, and therapeutic alliance when working with childhood interpersonal trauma survivors. Correlation analyses indicated that cultural humility and therapeutic presence were both significantly correlated with therapeutic alliance. Regression analyses revealed that together cultural humility, therapeutic presence and attachment anxiety were the strongest predictors of the therapeutic alliance. Implications and recommendations for professional counselors and counselor educators are provided

Efficient kinetic method for fluid simulation beyond the Navier-Stokes equation

We present a further theoretical extension to the kinetic theory based formulation of the lattice Boltzmann method of Shan et al (2006). In addition to the higher order projection of the equilibrium distribution function and a sufficiently accurate Gauss-Hermite quadrature in the original formulation, a new regularization procedure is introduced in this paper. This procedure ensures a consistent order of accuracy control over the non-equilibrium contributions in the Galerkin sense. Using this formulation, we construct a specific lattice Boltzmann model that accurately incorporates up to the third order hydrodynamic moments. Numerical evidences demonstrate that the extended model overcomes some major defects existed in the conventionally known lattice Boltzmann models, so that fluid flows at finite Knudsen number (Kn) can be more quantitatively simulated. Results from force-driven Poiseuille flow simulations predict the Knudsen's minimum and the asymptotic behavior of flow flux at large Kn

An Ecological Perspective of Intergenerational Trauma: Clinical Implications

In this paper, the authors present information about both intergenerational trauma and an ecological case conceptualization model to assist counselors as they develop treatment plans and determine appropriate interventions. Bronfenbrenner’s Ecological model is introduced as a way to help professional counselors in a variety of settings explore a more holistic understanding of presenting problems. The authors use a case illustration to highlight how to implement an ecological framework with a client with Colombian heritage to better understand and address intergenerational trauma as an important aspect of treatment planning. The paper includes clinical examples, clinical resources, and implications for professional counselors, so they can intentionally consider intergenerational trauma while working with a variety of clients

Detection of the glucocorticoid receptors in brain protein extracts by SDS-PAGE

Uncorrected proofGlucocorticoids are steroid hormones vital for organ system homeostasis and for the maintenance of essential biological processes. A significant part of these actions are mediated through glucocorticoid receptor (GR) that belongs to the nuclear receptor superfamily. To cover such variety of processes the different glucocorticoids act through different GR isoforms that are originated due to posttranscriptional and posttranslational mechanisms. For this reason when evaluating the levels of GRs we should preferentially determine protein levels instead of gene expression. Here, we describe the detection by Western blotting of the GR (a and ß isoforms) protein, using macrodissected brain tissue

Strong Shock Waves and Nonequilibrium Response in a One-dimensional Gas: a Boltzmann Equation Approach

We investigate the nonequilibrium behavior of a one-dimensional binary fluid on the basis of Boltzmann equation, using an infinitely strong shock wave as probe. Density, velocity and temperature profiles are obtained as a function of the mixture mass ratio \mu. We show that temperature overshoots near the shock layer, and that heavy particles are denser, slower and cooler than light particles in the strong nonequilibrium region around the shock. The shock width w(\mu), which characterizes the size of this region, decreases as w(\mu) ~ \mu^{1/3} for \mu-->0. In this limit, two very different length scales control the fluid structure, with heavy particles equilibrating much faster than light ones. Hydrodynamic fields relax exponentially toward equilibrium, \phi(x) ~ exp[-x/\lambda]. The scale separation is also apparent here, with two typical scales, \lambda_1 and \lambda_2, such that \lambda_1 ~ \mu^{1/2} as \mu-->0$, while \lambda_2, which is the slow scale controlling the fluid's asymptotic relaxation, increases to a constant value in this limit. These results are discussed at the light of recent numerical studies on the nonequilibrium behavior of similar 1d binary fluids.Comment: 9 pages, 8 figs, published versio

Incorporating Forcing Terms in Cascaded Lattice-Boltzmann Approach by Method of Central Moments

Cascaded lattice-Boltzmann method (Cascaded-LBM) employs a new class of collision operators aiming to improve numerical stability. It achieves this and distinguishes from other collision operators, such as in the standard single or multiple relaxation time approaches, by performing relaxation process due to collisions in terms of moments shifted by the local hydrodynamic fluid velocity, i.e. central moments, in an ascending order-by-order at different relaxation rates. In this paper, we propose and derive source terms in the Cascaded-LBM to represent the effect of external or internal forces on the dynamics of fluid motion. This is essentially achieved by matching the continuous form of the central moments of the source or forcing terms with its discrete version. Different forms of continuous central moments of sources, including one that is obtained from a local Maxwellian, are considered in this regard. As a result, the forcing terms obtained in this new formulation are Galilean invariant by construction. The method of central moments along with the associated orthogonal properties of the moment basis completely determines the expressions for the source terms as a function of the force and macroscopic velocity fields. In contrast to the existing forcing schemes, it is found that they involve higher order terms in velocity space. It is shown that the proposed approach implies "generalization" of both local equilibrium and source terms in the usual lattice frame of reference, which depend on the ratio of the relaxation times of moments of different orders. An analysis by means of the Chapman-Enskog multiscale expansion shows that the Cascaded-LBM with forcing terms is consistent with the Navier-Stokes equations. Computational experiments with canonical problems involving different types of forces demonstrate its accuracy.Comment: 55 pages, 4 figure

A causal statistical family of dissipative divergence type fluids

In this paper we investigate some properties, including causality, of a particular class of relativistic dissipative fluid theories of divergence type. This set is defined as those theories coming from a statistical description of matter, in the sense that the three tensor fields appearing in the theory can be expressed as the three first momenta of a suitable distribution function. In this set of theories the causality condition for the resulting system of hyperbolic partial differential equations is very simple and allow to identify a subclass of manifestly causal theories, which are so for all states outside equilibrium for which the theory preserves this statistical interpretation condition. This subclass includes the usual equilibrium distributions, namely Boltzmann, Bose or Fermi distributions, according to the statistics used, suitably generalized outside equilibrium. Therefore this gives a simple proof that they are causal in a neighborhood of equilibrium. We also find a bigger set of dissipative divergence type theories which are only pseudo-statistical, in the sense that the third rank tensor of the fluid theory has the symmetry and trace properties of a third momentum of an statistical distribution, but the energy-momentum tensor, while having the form of a second momentum distribution, it is so for a different distribution function. This set also contains a subclass (including the one already mentioned) of manifestly causal theories.Comment: LaTex, documentstyle{article

Hydrodynamics of probabilistic ballistic annihilation

We consider a dilute gas of hard spheres in dimension $d \geq 2$ that upon collision either annihilate with probability $p$ or undergo an elastic scattering with probability $1-p$. For such a system neither mass, momentum, nor kinetic energy are conserved quantities. We establish the hydrodynamic equations from the Boltzmann equation description. Within the Chapman-Enskog scheme, we determine the transport coefficients up to Navier-Stokes order, and give the closed set of equations for the hydrodynamic fields chosen for the above coarse grained description (density, momentum and kinetic temperature). Linear stability analysis is performed, and the conditions of stability for the local fields are discussed.Comment: 19 pages, 3 eps figures include

Relativistic Dissipative Hydrodynamics: A Minimal Causal Theory

We present a new formalism for the theory of relativistic dissipative hydrodynamics. Here, we look for the minimal structure of such a theory which satisfies the covariance and causality by introducing the memory effect in irreversible currents. Our theory has a much simpler structure and thus has several advantages for practical purposes compared to the Israel-Stewart theory (IS). It can readily be applied to the full three-dimensional hydrodynamical calculations. We apply our formalism to the Bjorken model and the results are shown to be analogous to the IS.Comment: 25 pages, 2 figures, Phys. Rev. C in pres

Derivation of fluid dynamics from kinetic theory with the 14--moment approximation

We review the traditional derivation of the fluid-dynamical equations from kinetic theory according to Israel and Stewart. We show that their procedure to close the fluid-dynamical equations of motion is not unique. Their approach contains two approximations, the first being the so-called 14-moment approximation to truncate the single-particle distribution function. The second consists in the choice of equations of motion for the dissipative currents. Israel and Stewart used the second moment of the Boltzmann equation, but this is not the only possible choice. In fact, there are infinitely many moments of the Boltzmann equation which can serve as equations of motion for the dissipative currents. All resulting equations of motion have the same form, but the transport coefficients are different in each case.Comment: 15 pages, 3 figures, typos fixed and discussions added; EPJA: Topical issue on "Relativistic Hydro- and Thermodynamics
