Trauma and disorganized attachment in refugee children : integrating theories and exploring treatment options

Refugee families incur many different types of stressors in the course of the phases prior to flight, those of flight, and resettlement. Multiple and varied negative life events and traumas, such as those experienced by refugee families, may give rise to negative changes in attachment between children and their parents. However, such negative changes in attachment may be countered through the use of culturally appropriate counselling theories and their respective interventions. The integration of attachment theory with family systems, trauma systems, and cognitive behavioural theories and the use of cognitive behavioural caregiver support, filial therapy training, and play therapy interventions are discussed as a treamtent framework for promoting more positive and secure attachments between refugee children and their caregivers.

Violencia doméstica: sexo y género en las teorías psicosociales sobre la violencia. Hacia otras propuestas de comprensión e intervención = Domestic violence: sex and gender in psychosocial theories about violence. New approach to it comprehension and intervention

En el artículo se presenta la violencia doméstica como violencia política de género masculino. Se señalan el individualismo, la naturalización y el sexismo en el tratamiento de la violencia y la agresión así como de la identidad, por parte de la psicología tradicional, como factores que dificultan las intervenciones en la violencia doméstica. Los prejuicios, valores y estrategias de la sociedad patriarcal continúan influyendo en ellas. Desde la psicología crítica feminista se propone: a) una comprensión de la subjetividad, la diferencia sexo-género y la violencia como construcciones sociales; b) intervenciones menos autoritarias y que no participen en la reproducción del orden social; c) la incorporación de las resistencias desarrolladas; d) un análisis basado en las relaciones de poder y las prácticas discursivas

Holographic collisions in confining theories

We study the gravitational dual of a high-energy collision in a confining gauge theory. We consider a linearized approach in which two point particles traveling in an AdS-soliton background suddenly collide to form an object at rest (presumably a black hole for large enough center-of-mass energies). The resulting radiation exhibits the features expected in a theory with a mass gap: late-time power law tails of the form t −3/2, the failure of Huygens" principle and distortion of the wave pattern as it propagates. The energy spectrum is exponentially suppressed for frequencies smaller than the gauge theory mass gap. Consequently, we observe no memory effect in the gravitational waveforms. At larger frequencies the spectrum has an upward-stairway structure, which corresponds to the excitation of the tower of massive states in the confining gauge theory. We discuss the importance of phenomenological cutoffs to regularize the divergent spectrum, and the aspects of the full non-linear collision that are expected to be captured by our approach.

N=1 SQCD-like theories with N_f massive flavors from AdS/CFT and beta functions

We study new supergravity solutions related to large-N c N=1 supersymmetric gauge field theories with a large number N f of massive flavors. We use a recently proposed framework based on configurations with N c color D5 branes and a distribution of N f flavor D5 branes, governed by a function N f S(r). Although the system admits many solutions, under plausible physical assumptions the relevant solution is uniquely determined for each value of x ≡ N f /N c . In the IR region, the solution smoothly approaches the deformed Maldacena-Núñez solution. In the UV region it approaches a linear dilaton solution. For x < 2 the gauge coupling β g function computed holographically is negative definite, in the UV approaching the NSVZ β function with anomalous dimension γ 0 = −1/2 (approaching − 3/(32π 2)(2N c  − N f )g 3)), and with β g  → −∞ in the IR. For x = 2, β g has a UV fixed point at strong coupling, suggesting the existence of an IR fixed point at a lower value of the coupling. We argue that the solutions with x > 2 describe a"Seiberg dual" picture where N f  − 2N c flips sign.

The political role of the State in Cambridge theories of growth and distribution

In this paper we extend Kaldor’s Neo-Pasinetti theorem to the scope of budgetary interventions based on political orientations. First, we take into account a system of taxes and expenditures. Second, we introduce different reaction functions for public spending showing the political role of the State in Cambridge theory of distribution. It turns out that the validity of Kaldorian results depends on the political orientation adopted by government, which diminishes the range of application of the Neo-Pasinetti theorem.

Implicit self-theories of shyness : predictors and correlates in preadolescence /

Implicit theories of shyness refer to a beUef that shyness is a fixed trait versus the belief that shyness is changeable and controllable. In this study, I explored the association between overall shyness and children's implicit self-theories of shyness, as well as between implicit self-theories of shyness and children's other shyness-related beliefs (perceptions of others' theories of shyness, shyness as a perceived problem, and ideas about treatment for shyness). Forty-six 10-12- year- old children (M = 10.74, SD = .88) were interviewed individually, filled out a set of questionnaires, and completed a computer-presented task. ' "^ As was expected, in ambiguous social situations, children perceived others' theories of shyness in a way that confirmed their own theories. The hypothesized curvilinear relation between shy and implicit self-theories of shyness was not found; instead, a linear positive relationship between these two variables emerged. Although implicit self-theories of shyness were not effective in predicting either the children's views of shyness as a perceived problem or children's ideas about treatment for shyness, some interesting results were found. Specifically, children's motivation to change their shyness correlated with their views of shyness as a problem for children in general and their perceptions of others' theories of shyness. Specific agents and strategies were regarded by children as having different effectiveness in their potential to change shyness. The theoretical and practical implications of these findings were discussed. Suggestions for future research were provided.
