Abstract The study of the mechanisms of formation of misfit dislocations in latticemismatched semiconductor interfaces requires a comprehensive characterization of these dislocations. In particular the determination of the sense of their Burgers vectors by transmission electron microscopy makes it possible to show that they contribute to removing part of the mismatched-induced interfacial strain. Furthermore the nature (αorβ) of the dislocations can then be determined. The different methods of determination of the sense of Burgers vectors are reviewed and then applied to InGaAs/GaAs superlattices. 相似文献

A limitation of the morningness–eveningness literature is the assumption that morningness is a ‘fixed’ construct. Morningness–eveningness scales are often developed on young adult samples, yet studies report that eveningness peaks in young adults with a shift to morningness from the age of 25 to 35 years of age. This age related change in morningness–eveningness may explain why these scales have limited success when applied in older samples. We tested this argument by developing a measurement model based on the Composite Scale of Morningness using a sample aged <30 years of age. Tucker’s congruence coefficient and confirmatory factor analysis indicated this solution was not a good fit in three older age groups. In contrast, we repeated this assessment using the ‘morning affect’ scale. This scale comprises items that measure morningness preference only. Model fit indicators suggested the ‘morning affect’ scale was a good fit across four age groups and gender. 相似文献

Psychoanalytic theory offers a varied conceptual system for considering psychosis by providing a coherent representation of the anxieties and processes at work in adult patients. But at the practical clinical level, it is not enough simply to ‘think about psychosis’ and have a theoretical system in place. The therapist must also ‘have psychosis in mind’, that is, get to grips with its forms of logic, gain familiarity with its workings, and learn to understand and accept the effects it has on the therapeutic relationship and on their own expectations. Clinicians engaged in this type of work must be able to tolerate getting back in touch with processes deemed archaic at the core of their own psychological functioning, which will impact their ability to listen and think. These chaotic processes demand a change of approach since they cause a ‘desymbolisation’ that perturbs the internal mental structure of the therapist. This ‘desymbolisation’ is therefore the locus of the therapeutic work, which must attempt to render it comprehensible and represent it. A case study illustrates these processes. 相似文献

Behavioral and psychological symptoms of dementia, including depression, might complicate the course of the disorder additionally. Dementia is more frequent in older people and suicide rates are higher in later life than in any other age group. To explore the phenomenology of suicidal behavior in patients with dementia, we searched electronic databases and key journals for original research and review articles on suicide in demented patients using the search terms “suicide, suicidal behavior, dementia, Alzheimer disease, and old age”. Although cognitive impairment could result in a diminishing ability to think flexibly and to solve problems or to cope with conflict, in the early stage of dementia such impairments are absent or mild, and suicidal behavior might be expected, especially following diagnosis. In addition, personality changes based on declining cognitive capacity and the neurochemical imbalances described in late-life depression and in dementia may predispose patients to aggressive or impulsive acts, such as suicide attempt. The literature on suicidal behavior and dementia highlights the need for further research in this area. 相似文献

A substantial body of research has established that emotion understanding develops throughout early childhood and has identified three hierarchical developmental phases: external, mental, and reflexive. The authors analyzed nonverbal intelligence and its effect on children's improvement of emotion understanding and hypothesized that cognitive level is a consistent predictor of emotion comprehension. In all, 366 children (182 girls, 184 boys) between the ages of 3 and 10 years were tested using the Test of Emotion Comprehension and the Coloured Progressive Matrices. The data obtained by using the path analysis model revealed that nonverbal intelligence was statistically associated with the ability to recognize emotions in the 3 developmental phases. The use of this model showed the significant effect that cognitive aspect plays on the reflexive phase. The authors aim to contribute to the debate about the influence of cognitive factors on emotion understanding. 相似文献

This study examines the psychometric properties of the French-Canadian Modified PTSD Symptom Scale (MPSS-FC) in a sample of French-Canadian undergraduates. Findings uncovered a 3-dimensional model for the Frequency and Severity scales, which shared factorial invariance. In addition, the MPSS-FC scales had adequate internal consistency and a satisfactory 5-week test-retest reliability. In view of its satisfactory psychometric properties, the MPSS-FC seems promising as a brief screening measure of PTSD. Indeed, the MPSS-FC as a stand-alone measure could be used with a population known to have been exposed to a traumatic event. 相似文献

In this paper, I put forward some remarks supporting a reading of Spinoza's metaphysics in terms of process ontology, that is, the notion that processes or activities, rather than things, are the most basic entities. I suggest that this reading, while not the only possible one, offers advantages over the traditional substance‐properties interpretation. While this claim may sound implausible vis‐à‐vis Spinoza's language of ‘substance’ and ‘attributes’, I show that process ontology illuminates important features of Spinoza's thought and can facilitate solutions to some interpretive problems. 相似文献

The present study was based on psycholexical approach premises and explored the structure of a large set of personality attribute‐nouns in the Italian language. Content inspection (based on Big Five categories) and quantitative indices were used to interpret the attribute‐noun dimensions. Results showed (a) a stable three‐component solution which replicated the Big Three; (b) an unstable five‐factor solution which did not reproduce the Big Five; (c) an unstable six‐factor solution which represented deviations from the Big Five system, which have been found in most psycholexical studies conducted in the Italian language. The six lexical dimensions were interpreted as follows: Conscientiousness (replicating the III of the Big Five); Self‐Assurance (combining the Big Five I assertiveness and IV fearfulness subcategories); Sociability (defined by the Big Five I sociableness and I impulse expression subcategories); Placidity (combining the Big Five II peacefulness, II unassertiveness, and IV irritableness subcategories); Honesty and Humility (comprising the Big Five II modesty and II helpfulness subcategories plus integrity values); Cleverness and Sophistication (defined by the Big Five V subcategories). The conclusion was that personality word organisation in the Italian language reflects the psycholexical Big Three and Big Six, but not the Big Five. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献
