Dislocation formation in the partially coherent interfaces of an embedded layer in a semi-infinite matrix

The formation of two misfit edge dislocations is theoretically investigated in the interfaces of a layer embedded in a semi-infinite matrix. Assuming the matrix–layer interfaces are partially coherent, the energy variation resulting from the formation of the dislocations from the lateral free surface of the structure has been determined in the shearing stress field due to the partial misfit. The mechanical stability of the structure is analysed with respect to the dislocation formation as a function of the size of the coherent region of the interface and the misfit strain.     

Self‐Monitoring and the Metatraits

Prior attempts at locating self‐monitoring within general taxonomies of personality traits have largely proved unsuccessful. However, past research has typically neglected (a) the bidimensionality of the Self‐Monitoring Scale and (b) the hierarchical nature of personality. The objective of this study was to test hypotheses that the two self‐monitoring factors are located at the level of the metatraits. Using data from two large multi‐informant samples, one community (Sample 1: N = 552, M_age = 51.26, 61% female; N_Peers = 1,551, M_age = 48.61, 37% female) and one online (Sample 2: N = 3,726, M_age = 24.89, 59% female; N_Peers = 17,868, M_age = 26.23, 64% female), confirmatory factor analysis was used to test the hypotheses. Results confirmed hypotheses that acquisitive self‐monitoring would have a strong positive relation to metatrait Plasticity, whereas protective self‐monitoring would have a moderate negative relation to metatrait Stability. In both samples, constraining the correlation between acquisitive self‐monitoring and Plasticity to unity did not alter model fit indices, indicating that the two putatively distinct constructs are identical. Findings have wide‐ranging implications, including integration of the construct of self‐monitoring into the mainstream of personality research, as the latter moves toward the development of broad explanatory theories.     

Seeking Security in the Face of Fear: The Disorganized Dilemma

Attachment theory has been instrumental in identifying insecure disorganized attachment as a developmental pathway that leads to severe psychopathology in adults. Psychotherapy with these patients is challenging, offering a confusing pattern of relatedness, difficulties in mentalizing, problems expressing affect, utilizing dissociative defenses, and trying to gain an understanding of their subjectivity. This article provides a theoretical overview of disorganized attachment focusing on its etiology and how it presents throughout the life span. It reviews important therapeutic guidelines that help navigate the relationship with adults and presents a case study highlighting some clinical challenges.     

If merely more words,what is the point? A critical response

A critical response is given to the five articles constituting the special issue theme ‘Critical psychotherapy and counselling: if not now, when?’ The related arguments concerning political justice, professional struggles, new public management, therapeutic language use and ecotherapy are considered concisely and challenges made. Into this discussion is injected a degree of ‘brutalist objection’, along with a recommendation for radical honesty, a confession of depressive realism and hints of nihilism. Psychotherapy, whether traditional or critical, is taken to task for its romantic enmeshment in a hubristic fantasy of infinite relevance and improvement.     

Ubuntu and Freedom of Expression

This article critically addresses the view that ubuntu values limiting freedom of expression to what elders find agreeable. I present a heterogeneous argument in favor of an attractive conception of ubuntu that values individuals by investing in the worth of community. I assume that socioeconomic development is directly related to the extent to which people are granted freedom of expression. The point is that freedom of expression enables everyone to be respected and governed in ways that are associated with the establishment of communities where everyone can be the most they can be.     

An Electrophysiological Investigation of the Effects of Social Rejection on Self Control

Previous studies have shown that social rejection leads to impaired performance on a variety of tasks that require self control, including the Stroop color-word interference task; however, mechanisms underlying the effect remain to be elucidated. We attempted to clarify the effects of social rejection on self control resources by measuring event-related potentials (ERPs) during a computerized Stroop test. Stroop performance and ERPs from 54 participants in rejected, control, and accepted groups were analyzed. A significant difference in the pattern of results for the N450 ERP was found, with rejected participants showing less negativity on incongruent trials and more on congruent trials compared to accepted participants and controls. The results suggest social rejection reduces the engagement of cognitive control mechanisms, and are more consistent with a limited strength resource model than with limited capacity resource models that focus on limitations in attention.
