Frequency of borderline personality disorder among psychiatric outpatients in Shanghai

The objective of this study was to investigate the frequency, clinical characteristics, and comorbidity of borderline personality disorder (BPD) among psychiatric outpatients in two clinics at Shanghai Mental Health Center. A cross-sectional investigation was conducted. From 3,075 outpatients screened using the Personality Diagnostic Questionnaire-IV+, 2,284 patients positive for a personality disorder were assessed using the Structured Clinical Interview for DSM-IV Personality Disorders. The frequency of BPD among the psychiatric outpatients was 5.8%, with a frequency of 3.5% among males and 7.5% among females (p < .01). BPD was found to have extensive comorbidity with Axis I and II disorders. This study proves that BPD does occur in China. The detected frequency among outpatients is lower than that reported in North America.     

情绪智力在农村留守老人感恩与自我和谐之间的效应:中介还是调节

该研究为了考察农村留守老人感恩、情绪智力和自我和谐之间的关系及作用机制,采用问卷法调查了153名子女打工在外的农村老人。结果表明:(1)农村留守老人的感恩和情绪智力水平较高,自我和谐程度偏低;(2)自我和谐在健康状况上的主效应显著,健康状况与子女联系状况的交互作用也显著;(3)感恩与农村留守老人的自我和谐呈显著负相关;(4)情绪智力在感恩与自我和谐的关系中发挥着部分中介效应;(5)情绪智力不是调节变量,不会显著影响感恩与自我和谐之间关系的强度和方向。     

Different efficiencies of attentional orienting in different wandering minds

This study examined the relations between properties of attentional networks and Mind Wandering (MW) across individuals. For the attentional networks, we measured three components of attention, known as alerting, orienting, and executive control, using the Attention Network Test (ANT). To investigate MW, we measured thought probes embedded in the Sustained Attention to Response Task (SART). Moreover, four performance characteristics of the SART were calculated as behavioral indices of MW. Three of them showed significant associations with probed MW. Most research regarding MW focused on its relation to executive functions, while the present study revealed that MW, as indexed by self-reports and RT variability, was negatively correlated with orienting, specifically the exogenous orienting system. Furthermore, there was a positive association between RT variability and executive control. Our results suggest that individuals with higher tendency of MW are less sensitive to irrelevant external stimuli, supporting the decoupling hypothesis of MW.     

False-belief understanding in 2.5-year-olds: evidence from two novel verbal spontaneous-response tasks

Recent research indicates that toddlers and infants succeed at various non-verbal spontaneous-response false-belief tasks; here we asked whether toddlers would also succeed at verbal spontaneous-response false-belief tasks that imposed significant linguistic demands. We tested 2.5-year-olds using two novel tasks: a preferential-looking task in which children listened to a false-belief story while looking at a picture book (with matching and non-matching pictures), and a violation-of-expectation task in which children watched an adult 'Subject' answer (correctly or incorrectly) a standard false-belief question. Positive results were obtained with both tasks, despite their linguistic demands. These results (1) support the distinction between spontaneous- and elicited-response tasks by showing that toddlers succeed at verbal false-belief tasks that do not require them to answer direct questions about agents' false beliefs, (2) reinforce claims of robust continuity in early false-belief understanding as assessed by spontaneous-response tasks, and (3) provide researchers with new experimental tasks for exploring early false-belief understanding in neurotypical and autistic populations.     

跨期选择中偏好反转的心理机制

通过直接测量近期和远期选择中备选项激活的情绪、间隔的时间知觉及对备选项金额差异和时间间隔的重视程度,以探究跨期选择中偏好反转产生的心理机制。结果表明：（1）近期选择中,备选项激活的情绪强度差异显著,而远期选择中两者的差异不显著;（2）近期和远期选择中,情绪强度差异和时间知觉差异能够预测偏好反转的发生。研究结果支持了偏好反转的情绪激活差异假说和时间知觉差异假说。     

Discontinuous cracking of TiN films on a steel substrate induced by an adhesive interlayer

ABSTRACT

The basic mechanisms governing the process of cracking of single-layer brittle films have been extensively explored through both simulations and experiments. However, the role that an adhesive interlayer plays in the cracking of the overlying brittle film remains unclear. By performing three-point bending experiments, we observed that the insertion of a 100?nm thick Ti interlayer changed the cracking behaviour of TiN films from a continuous pattern to a discontinuous pattern. The slight change in the microstructure of the film and the increase in film thickness arising from the addition of the Ti interlayer are unlikely to cause the observed cracking morphology. The combination of the different interface between the Ti and the steel substrate and the fracture of the Ti interlayer are responsible for the transition in the TiN film cracking morphologies.     

A study of the spin-Hamiltonian parameters for Cr5+ at the rhombically-distorted tetrahedral P5+ site of Ca2PO4Cl crystal using a two-mechanism model

The complete high-order perturbation formulae of spin-Hamiltonian (SH) parameters (g factors g_i and hyperfine structure constants A_i , where i = x, y, z) containing contributions from both the crystal-field (CF) and charge-transfer (CT) mechanisms (the latter mechanism is neglected in the widely-used CF theory) are established for d¹ ions in rhombic tetrahedra. From these formulae, the SH parameters of Cr⁵⁺ ion at the rhombically-distorted tetrahedral P⁵⁺ site of Ca₂PO₄Cl crystal are calculated. The CF and CT energy levels used in the calculation are obtained from the optical spectra of the studied Ca₂PO₄Cl : Cr⁵⁺ crystal. The calculated results showed reasonable agreement with the experimental values. The signs of the hyperfine structure constants A_i and the relative importance of the CT mechanism to SH parameters are acquired from the calculations.     

Interaction of a dislocation with an elliptical hole in icosahedral quasicrystals

The interaction between a dislocation and an elliptical hole in icosahedral quasicrystals is considered. An explicit expression for the complex potential is derived using the extended Stroh formalism. Based on the conformal mapping method and a perturbation technique, closed-form solutions are obtained. The field intensity factors at a crack tip and the image forces on the dislocation arising from the crack are calculated. The effects of phonon–phason elastic coupling on the mechanical behavior are also observed.     

Similarity grouping as feature-based selection

Our visual system groups objects with similar features, such as colour, orientation, or shape. We argue that similarity grouping is nothing more than global selection of a certain feature value, such as red, horizontal, or circular. This account makes the striking prediction that only one feature group can be created at a time. Here we provide the most direct evidence yet for this proposal, using a number estimation task that forces simultaneous processing of all objects. Multiple similarity cues failed to produce grouping in this task, in contrast to proximity, connectivity, and common region, which all showed strong grouping effects.     

Reflections on relational readings of organizational learning

In this concluding article we further reflect on relational readings of organizational learning and how they can contribute to organization studies and organizing practices. As has been seen, the root metaphor of “organizational learning” takes a variety of forms. These include “product-oriented” pictures such as learning curves, strategy, and business processes, and the generative metaphor of organizational learning as conversations-for-new-possibilities. This special issue highlights the contribution of learning-as-conversations, especially in those organizational instances where the organizing is “in-the-making” and where the creation of a transitional space can be a new meeting ground for participants. In an increasingly globalized world we are more and more in need of the ability to construct such transitional and possibility-enabling practices. It can be a task of work and organizational psychology to contribute ideas and practices for this endeavour.
