Depressive symptoms, cortisol, and cognition during human aging: the role of negative aging perceptions

Depressive symptoms and memory impairments are associated with heightened stress hormone levels during aging. A factor that is related to memory deficits during aging is internalized negative aging stereotypes; the idea people have about the process of aging. In this study, we assessed the associations between internalized negative aging stereotypes, depressive symptoms, subjective and objective memory assessments, and cortisol concentration among older adults. Forty older adults aged between 58 and 85 years (18 females and 22 males; mean age?±?SD: 71.25?±?8.80 years) were assessed in this study. Measures of internalized negative aging stereotypes, depressive symptoms, and both subjective and objective memory performance were assessed. Salivary samples were obtained for measurement of cortisol concentration. Stepwise linear regressions were executed in our main analyses. Internalized negative aging stereotypes were associated with increased depressive symptoms and subjective memory complaints. No significant differences were observed for objective memory performance, or cortisol concentration. Internalized negative aging stereotypes are associated with increased depressive symptomatology and subjective complaints of memory; however, they do not predict increased cortisol concentration nor objective memory performance during aging. These results indicate that the mechanism underlying the association between internalized negative aging stereotypes and cognitive impairments may not be related to dysregulations of cortisol secretion among older adults.     

大学生心理需求及其满足与网络成瘾的关系

以武汉地区1183名大学生为被试,通过问卷调查探讨大学生心理需求程度及其在现实和网络中的满足程度与网络成瘾的关系。结果表明：与非网络成瘾大学生相比,网络成瘾大学生的心理需求的网络满足更多而现实满足更低,但两组大学生的心理需求程度并无明显差异;网络成瘾大学生的心理需求与网络满足的相关高于与现实满足的相关,但非成瘾大学生不存在这种差异;心理需求现实满足高但网络满足低的大学生网络成瘾的比率最低,而心理需求现实满足低网络满足高的大学生网络成瘾的比率最高。     

Nonexpert Evaluations on Architectural Design Creativity Across Cultures

This article examines the relationship between cultural differences and the nonexpert evaluations of architectural design creativity. In study I, Caucasian Americans (N = 126) and East Asians (N = 137), who did not major in architecture and urban design, evaluated the novelty and appropriateness of 5 unusual architectural shapes, selected by 5 experts in the field of architecture. In study II, the 2 cultural groups selected preferred alternatives from 3 pairs of silhouettes of architectural shapes that were distinctive and indistinctive from the adjacent environments. The data were collected by an online survey tool. Multiple analysis of variance (MANOVA) and subsequent t-tests revealed that East Asians awarded lower scores as regards the novelty and appropriateness of unusual, novel architectural forms, and that they accepted unusual and distinctive architectural shapes less than the Caucasian Americans did. These results indicated that cultural differences between these 2 groups affected the nonexpert creativity evaluations, as introduced in previous cross-cultural studies. The East Asians’ creativity evaluations and preference tests were possibly influenced by their perceptions of contextual information and emphasis on the holistic and interdependent relationships amongst environmental elements, whereas the Caucasian Americans’ evaluations were related to their analytic tendency to be aware of focal objects and independent identity.     

Cultural knowledge,category label,and social connections: Components of cultural identity in the global,multicultural context

Cultural identity refers to the psychological connection between an individual's self and a culture. In this paper, we identify three components that make up an individual's cultural identity – cultural knowledge, category label, and social connections. The cultural knowledge component connects an individual with a culture through the individual's direct endorsement of what are widely known to be the culture's central characteristics. The category label component connects an individual with a culture through the individual's depersonalized membership in a cultural collective. The social connections component connects an individual with a culture through networks of specific social relationships. The three components are conceptually distinct, and yet may have interconnections in influencing the development of cultural identity. We examine the implications of the three components on cultural identification processes in the context of multiculturalism and global cultural contact.

Atomic configurations of twin boundaries and twinning dislocation in superconductor Y0.6Na0.4Ba2Cu2.7Zn0.3O7− δ

Two types of twin boundaries in superconductor Y_0.6Na_0.4Ba₂Cu_2.7Zn_0.3O_{7? δ} , the cation-centered and oxygen-centered types, and the associated twinning dislocation have been studied by high-resolution electron microscopy. The structure map projected in the [001] direction was obtained from a single image by means of the image deconvolution technique. In this map, all columns of metallic atoms appear as individual black dots, and hence the two types of twin boundaries are distinguished from each other at atomic level. It is seen that the twinning dislocation occurs when the two types of twin boundaries meet each other. The structure model of the twinning dislocation together with the two types of twin boundaries has been derived straightforwardly based on the positions of black dots seen in the deconvoluted image.     

The Dialogue of Ḥikma: Generating Harmony in Muslim–Non-Muslim Relations

This article seeks to explain the concept of the dialogue of ?ikma as a qur'anic principle in developing harmony in Muslim–non-Muslim relations. Living together harmoniously is essential in a community made up of a myriad of cultures and religions. Efforts to create harmony can be realized through the dialogue of ?ikma and by inculcating it as the culture in daily life interaction. This is truly essential in the context of mixed-faith families. In order to explore how the dialogue of ?ikma can be applied in Muslim–non-Muslim relations, this article examines the experience of Muslim converts living together with their non-Muslim families of origin. The research was conducted through in-depth interviews with selected Muslim converts from a variety of cultural backgrounds, living in the area of Kota Kinabalu, Sabah. The results indicate that Muslim converts share similar experiences in applying the dialogue of ?ikma as a mechanism for solving family problem arising as a result of conversion to Islam.

新药临床试验中的反安慰剂效应

新药在临床试验中设立安慰剂对照需要患者知情同意,有违安慰剂暗示治疗的本意。在一种新药Ⅱ期临床试验中,发现告知与隐瞒设立安慰剂对照的事实,疗效差异明显。表明告知患者可能使用到安慰剂,会产生反安慰剂效应,影响疗效判定。提出疗效判定尽量使用客观指标、采用叠加设计、采用暂时隐瞒法、心理医生介入等4项对策。
