Using hypnosis to facilitate direct observation of multiple tics and self-monitoring in a typically developing teenager

A hypnotic induction technique was used to facilitate direct observation of multiple tics in a typically developing teenager in a home setting. A comprehensive habit reversal program then was implemented, including awareness training, competing response training, relaxation training, self-monitoring, social support and contingency management. Duration of relaxation was then self-monitored using a changing criterion design. The procedure eliminated multiple tics and achieved long-term maintenance of treatment gains. Implications for assessing and treating tics are discussed.

Field configured assembly: Programmed manipulation and self-assembly at the mesoscale

Field configured assembly is a programmable force field method that permits rapid, "hands-free" manipulation, assembly, and integration of mesoscale objects and devices. In this method, electric fields, configured by specific addressing of receptor and counter electrode sites pre-patterned at a silicon chip substrate, drive the field assisted transport, positioning, and localization of mesoscale devices at selected receptor locations. Using this approach, we demonstrate field configured deterministic and stochastic self-assembly of model mesoscale devices, i.e., 50 mum diameter, 670 nm emitting GaAs-based light emitting diodes, at targeted receptor sites on a silicon chip. The versatility of the field configured assembly method suggests that it is applicable to self-assembly of a wide variety of functionally integrated nanoscale and mesoscale systems.

Bandwidth limitation of two-port fed and self-phased quadrifilar helix antennas

The bandwidth of a resonant quadrifilar helix antenna (QHA) is shown to be strongly dependent on the design of the feed network. In this paper, we compare the impedance and radiation-pattern performance of two QHAs driven by different feed arrangements. A qualitative explanation for the difference in the behaviour of the antenna is given by observing the amplitude and phase distribution of the current in the helices.

Nationalism, Ethnicity and Self-Determination: A Paradigm Shift?

An ongoing paradigm shift is giving birth to a more multidimensional understanding of the relationship between nationalism, sovereignty, self determination and democratic governance. A common element across the various versions of the new paradigm is the dispersal of democratic governance across multiple and overlapping jurisdictions. Governmental processes are no longer seen as discrete, centralised and homogenous as in the old nation-state model, but as asymmetrical, multilayered and multicultural, with devolution into multiple jurisdictions. These changes have hardly affected the two main conceptual frameworks that dominate the study of nationalism, Modernism and Ethnosymbolism. As a result, they risk becoming irrelevant to the new forms of national self determination, asymmetrical governance and shared sovereignty. Modernism and Ethnosymbolism insist that nationalism seeks to equate the nation with a sovereign state, while in reality the overwhelming majority of nations are stateless and unable to build nation states, as they often inhabit territories shared with other nations. The paradigm shift occurs precisely with the realisation that nation state sovereignty is no longer a feasible solution to the demands of stateless nations. Ethnosymbolism is in a much better position to adapt to the paradigm shift provided it abandons the claim that the nation state is the best shell for the nation.

Does chronic illness place constraints on positive constructions of identity? Temporal comparisons and self-evaluations in people with schizophrenia

It is often suggested that people in potentially threatening situations might engage in self-enhancing temporal comparisons that allow them to view themselves and their experience in a more positive light. Data from semistructured interviews with 12 individuals in the UK diagnosed as having schizophrenia were content analyzed to explore patterns of temporal comparison. The study found that the onset of schizophrenic symptoms created a new baseline in participants' representations of their past, with different types of temporal comparisons occurring before and after this point. Although comparisons with past selves after onset supported the suggestion that people may select and construct their past in such a manner that permits them to see their present circumstances more positively and envisage a better future, comparisons with past selves before onset were more negative. The findings suggest that the Theory of Temporal Self-Appraisals (Ross I Wilson, 2000) needs to be elaborated to include people who have experienced major life changes. (c) 2004 Elsevier Ltd.

Authorizing a tradition: Theory, criticism and (self-) canonization in French Caribbean writing

As critics have noted, Antillean literature has developed in tandem with a strong (self-) critical and theoretical body of work. The various attempts to theorize Antillean identity (négritude, antillanité, créolité) have been controversial and divisive, and the literary scene has been characterized as explosive, incestuous and self-referential. Yet writers aligned with, or opposed to, a given theory often have superior visibility. Meanwhile writers who claim to operate outside the boundaries of theory, such as Maryse Condé, are often canny theoretical operators who, from prestigious academic or cultural positions, manipulate readers’ responses and their own self-image through criticism. While recent polemics have helped to raise the critical stock of the islands generally, they have particularly enhanced the cultural capital of Chamoiseau and Condé, whose literary antagonism is in fact mutually sustaining. Both writers, through a strong awareness of (and contribution to) the critical field in which their work is read, position themselves as canonical authors.

Anger, aggression, and self-harm in PTSD and complex PTSD

This study examined the contribution of complex posttraumatic stress disorder (PTSD) diagnosis and symptomatology to the difficulties of anger, aggression, and self-harm in a Northern Ireland clinical community sample. A "current complex PTSD" (CCPTSD) group (n = 11) was compared with a "current PTSD" group (n = 31) on self-report measures of these variables. The CCPTSD group demonstrated significantly higher levels of physical aggression and selfharm than the PTSD group. The complex PTSD symptom of 'alterations in self-perception' was a significant predictor of aggression and history of self-harm, suggesting the potential role of posttraumatic shame and self-loathing in PTSD theoretical models of these destructive behaviors. Social desirability was a notable confounding influence in the assessment of anger, aggression, and self-harm in traumatised individuals.

Trauma typology as a risk factor for aggression and self-harm in a complex PTSD population: The mediating role of alterations in self-perception

This study examined the role of prolonged, repeated traumatic experiences such as childhood and sectarian trauma in the development of posttraumatic aggression and self-harm. Forty-four adult participants attending therapy for complex trauma in Northern Ireland were obtained via convenience sampling. When social desirability was controlled, childhood emotional and physical neglect were significant correlates of posttraumatic hostility and history of self-harm. These relationships were mediated by alterations in self-perception (e.g., shame, guilt). Severity of sectarian-related experiences was not related to self-destructive behaviors. Moreover, none of the trauma factors were related to overt aggressive behavior. The findings have implications for understanding risk factors for posttraumatic aggression and self-harm, as well as their treatment. © 2013 Copyright Taylor & Francis Group, LLC.

Universality and self-similarity of an energy-constrained sandpile model with random neighbors

We study an energy-constrained sandpile model with random neighbors. The critical behavior of the model is in the same universality class as the mean-field self-organized criticality sandpile. The critical energy E-c depends on the number of neighbors n for each site, but the various exponents are independent of n. A self-similar structure with n-1 major peaks is developed for the energy distribution p(E) when the system approaches its stationary state. The avalanche dynamics contributes to the major peaks appearing at E-Pk = 2k/(2n - 1) with k = 1,2,...,n-1, while the fine self-similar structure is a natural result of the way the system is disturbed.
