By atomic-scale high-angle annular dark-field scanning transmission electron microscopy, the long-period stacking ordered (LPSO) structures in a near-equilibrium Mg97Zn1Y2 (at.%) alloy have been characterised. In addition to 18R and 14H, new polytypes of LPSO structures are analysed and determined as 60R, 78R, 26H, 96R, 38H, 40H, 108H and 246R. All of these LPSO structures feature AB′C′A building blocks with two Mg layers and three Mg layers sandwiched between them. The Bravais lattices and space groups of new polytypes of LPSO structures were easily determined via the newly introduced method. A structural relationship between the LPSOs is proposed.  相似文献

有关数量化维度特征搜索的研究表明 ,目标搜索斜率 (反应时间对呈现项目数量函数的斜率 )是由目标与干扰子之间的差异决定的 ,然而以往研究中其差异的值取决于具体的实验条件。根据韦伯定律 ,笔者推测 ,目标搜索斜率应由目标与干扰子之间的相对差异 (C)决定 ,C为目标值 (T)与干扰子值 (D)的差值与该干扰子值的比值。当C值对应相等时 ,不同几何形状刺激的目标搜索斜率应无差异。为此笔者分别采用圆 (实验一 )和三角形 (实验二 )进行实验研究。实验结果支持了上述假设 ,并发现目标大于干扰子时的目标搜索斜率对C值的函数是单调递减函数  相似文献

A contraction-free and cut-free sequent calculus \(\mathsf {G3SDM}\) for semi-De Morgan algebras, and a structural-rule-free and single-succedent sequent calculus \(\mathsf {G3DM}\) for De Morgan algebras are developed. The cut rule is admissible in both sequent calculi. Both calculi enjoy the decidability and Craig interpolation. The sequent calculi are applied to prove some embedding theorems: \(\mathsf {G3DM}\) is embedded into \(\mathsf {G3SDM}\) via Gödel–Gentzen translation. \(\mathsf {G3DM}\) is embedded into a sequent calculus for classical propositional logic. \(\mathsf {G3SDM}\) is embedded into the sequent calculus \(\mathsf {G3ip}\) for intuitionistic propositional logic.  相似文献

Objective: Information about psychological intervention with couples coping with breast cancer is not well-disseminated. This can be explained, at least in part, by the absence of knowledge about the efficacy of this kind of intervention. The aim of the present systematic review is to identify and describe psychological interventions for couples coping with breast cancer and evaluate their efficacy.

Design: Studies identified by a searching multiple literature databases related to health and psychology between 1975 and 2013. Rigorous inclusion and exclusion criteria were utilised.

Results: Of 129 abstracts, 13 were extracted for further analysis and a final ten studies were deemed eligible for inclusion. Data were extracted from each study regarding study sample characteristics, design, results and methodological limitations. The results obtained were mixed in regard to efficacy, although the overwhelming majority of studies (eight studies) found benefits for both women and their partners in some dimensions, such as quality of life, psychological distress, relationship functioning and physical symptoms associated with cancer.

Conclusion: Psychological interventions for couples coping with breast cancer appear to be effective for both women and their partners. However, further studies are needed to evaluate the efficacy of couple-based interventions and, to identify for whom and how they are more effective.  相似文献

The discipline of epidemiology not only contributes to knowledge regarding the distribution and prevalence of mental disorders but also to a better understanding of their causes and consequences. This article focuses on the prevalence and disease burden. Epidemiological studies show that mental disorders are more common than previously thought and that they are associated with a particularly high societal burden. Costs of illness are higher in mental disorders compared to many widespread somatic conditions because of their high prevalence, chronic course, young age of first onset and the profile of disability. The extent of inability to work due to mental disorders is rising steadily although a general decline in absenteeism has been observed across other disease types. This raises the question of whether mental disorders have increased recently. Furthermore, the general need for treatment is discussed as well as the corresponding mental health care options. Finally, it has been found that, despite the quantitatively relatively well-developed health care system in Germany, there are still signs of a significant undertreatment in the field of psychotherapy.  相似文献

Previous research showed that handwriting production is mediated by linguistically oriented processing units such as syllables and graphemes. The goal of this study was to investigate whether French adults also activate another kind of unit that is more related to semantics than phonology, namely morphemes. Experiment 1 revealed that letter duration and inter-letter intervals were longer for suffixed words than for pseudo-suffixed words. These results suggest that the handwriting production system chunks the letter components of the root and suffix into morpheme-sized units. Experiment 2 compared the production of prefixed and pseudo-prefixed words. The results did not yield significant differences. This asymmetry between suffix and prefix processing has also been observed in other linguistic tasks. In suffixed words, the suffix would be processed on-line during the production of the root, in an analytic fashion. Prefixed words, in contrast, seem to be processed without decomposition, as pseudo-affixed words.  相似文献

Availability of brief, self-report measures to be used as screening instruments is crucial to detect correctly youth with social anxiety disorder and therefore, reach those otherwise under-detected and under-treated. A previous study revealed that the Social Phobia Inventory (SPIN) was potentially an appropriate measure for screening social anxiety among US adolescents. However, there is a lack of information concerning its properties as a screening test in other cultures and languages. This is the main objective of this study, although further validity of the scale is provided as well. The sample consisted of 192 adolescents (a sample composed of 114 subjects with a principal diagnosis of social anxiety disorder; and a group consisting of 78 subjects with no diagnosis of social phobia). Results suggest that the Social Phobia Inventory has demonstrated good psychometric properties and indeed may be used as a screening tool in Spanish-speaking adolescents.  相似文献

In this paper we use Hobby's duality for semi-De Morgan algebras, to characterize those algebras having only principal congruences in the classes of semi-De Morgan algebras, demi-pseudocomplemented lattices and almost pseudocomplemented lattices. This work extends some of the results reached by Beazer in [3] and [4].  相似文献
