铜镜与早期道教

AATOSMI从出土文物来看,从西汉末期开始,铜镜纹饰一扫春秋战国及汉初朴素简单的风格而趋于华丽与复杂,其中最突出的一点便是反映道家思想的题材广泛流行。西汉前期铸造的铜镜在纹饰上与战国镜相比并无多大差别,在样式及题材方面多继承战国,少有创新。至汉武帝时期,真正意义上的汉代铜镜开始兴起,东汉后期画像镜与神兽镜异军突起,其镜面纹饰大量采用神仙思想的题材。这其中有两个重要内容与早期道教关系极为密切:一是西王母为代表的道教神仙,二是渴求长生不老的镜铭。汉代画像镜中大量西王母及其他神仙画像的出现正是当时社会历史的真实反…     

Measuring Shaken Baby Syndrome awareness: preliminary reliability of a caregiver attitudes and beliefs survey

Recent estimates of Shaken Baby Syndrome awareness suggest that approximately half of all American adults have not heard of the often devastating risks of shaking an infant. Using a sample of 288 undergraduate students, we developed a measure of attitudes around infant care practices. A total of 264 community participants completed a revised survey. Between-group comparisons, exploratory factor analyses, and internal consistency tests were employed to determine the directionality and reliability of any scale structure present in the data. A five factor structure fits the data reliably, and each of these factors seems to represent a unique dimension. Implications for using this measure clinically and preventatively are discussed.     

Rats’ visual-spatial working memory: New object choice accuracy as a function of number of objects in the study array

When rats had to find new (jackpot) objects for rewards from among previously sampled baited objects, increasing the number of objects in the sample (study) segment of a trial from 3 to 5 and then to 7 (Experiment 1) or from 3 to 6 and 9 (Experiments 2 and 3) or from 6 to 9 and 12 (Experiment 4) did not reduce rats’ test segment performance. Increasing study segment size improved test segment performance contrary the limited-capacity hypothesis concerning rats’ spatial working memory. This effect occurred when objects either differed visually (Experiments 1, 2, 4) or only by odor (Experiment 3). Rats performed no better than chance in finding a jackpot on their first choice from among three visually different objects in Experiments 1 and 2. Furthermore, results from Experiments 2 and 3 indicate that differences in the probability of finding a jackpot by chance in Experiment 1 were not responsible for failure to find the predicted inverse relationship. Results from Experiment 4 indicate that those from Experiments 2 and 3 were not solely due to size of test arrays. We discussed whether our findings could be attributed to innate foraging or perceptual isolation processes during testing or to perceptual encoding processes during exposure to study segment arrays.     

A systematic literature review of the average IQ of sub-Saharan Africans

On the basis of several reviews of the literature, Lynn [Lynn, R., (2006). Race differences in intelligence: An evolutionary analysis. Augusta, GA: Washington Summit Publishers.] and Lynn and Vanhanen [Lynn, R., & Vanhanen, T., (2006). IQ and global inequality. Augusta, GA: Washington Summit Publishers.] concluded that the average IQ of the Black population of sub-Saharan Africa lies below 70. In this paper, the authors systematically review published empirical data on the performance of Africans on the following IQ tests: Draw-A-Man (DAM) test, Kaufman-Assessment Battery for Children (K-ABC), the Wechsler scales (WAIS & WISC), and several other IQ tests (but not the Raven's tests). Inclusion and exclusion criteria are explicitly discussed. Results show that average IQ of Africans on these tests is approximately 82 when compared to UK norms. We provide estimates of the average IQ per country and estimates on the basis of alternative inclusion criteria. Our estimate of average IQ converges with the finding that national IQs of sub-Saharan African countries as predicted from several international studies of student achievement are around 82. It is suggested that this estimate should be considered in light of the Flynn Effect. It is concluded that more psychometric studies are needed to address the issue of measurement bias of western IQ tests for Africans.     

Self-Objectification, Self-Esteem, and Gender: Testing a Moderated Mediation Model

The purpose of the present research was to test the mediating roles of body shame and appearance anxiety in the relation between self-surveillance and self-esteem; and to investigate whether gender (male, female) and stereotypical gender roles (masculinity, femininity) moderated the proposed mediation model. Canadian undergraduate university men and women (n?=?198) completed measures of self-surveillance, gender, gender roles, body shame, appearance anxiety, and self-esteem. Regression analyses demonstrated that greater self-surveillance predicted lower self-esteem, and this relation was fully mediated by body shame and appearance anxiety. With the exception of masculinity interacting with self-surveillance to predict body shame and appearance anxiety, neither gender nor stereotypical gender roles moderated the proposed paths. Implications are discussed.     

Interpersonal Psychotherapy for Co-occurring Depression and Chronic Pain

Up to 37% of individuals experience chronic pain during their lifetimes. Approximately one-fourth of primary care patients with chronic pain also meet criteria for major depression. Many of these individuals fail to receive psychotherapy or other treatment for their depression; moreover when they do, physical pain is often not addressed directly. Women, socioeconomically disadvantaged individuals, African Americans and Latinos all report higher rates of pain and depression compared to other groups. This article describes a version of Interpersonal Psychotherapy tailored for patients with comorbid depression and chronic pain, Interpersonal Psychotherapy for Depression and Pain (IPT-P). While IPT-P potentially could be delivered to many different patient populations in a range of clinical settings, this article focuses on its delivery within primary care settings for socioeconomically disadvantaged women. Adaptations include a brief 8-session protocol that incorporates strategies for anticipating barriers to psychotherapy, accepting patients' conceptualization of their difficulties, encouraging patients to consider the impact of their pain on their roles and relationships, emphasizing self-care, incorporating pain management techniques, and flexible scheduling. In addition, IPT-P is designed as an adjunct to usual medical pain treatment, and seeks to engage non-treatment seeking patients in psychotherapy by focusing on accessibility and relevance of the intervention to concerns common among patients with pain. Identifying patients with comorbid depression and chronic pain and offering IPT-P as a treatment option has the potential to improve clinical outcomes for individuals with depression and chronic pain.     

Addressing the Chronic Sorrow of Long‐Term Spousal Caregivers: A Primer for Counselors

Chronic sorrow is described as a distinct grief reaction that occurs when loss is not final but continues to be present in the life of the griever. It is characteristic of a growing number of older individuals who are providing long‐term care at home for a spouse or primary partner with progressive disability. The unique presentations of grief, depression, and anxiety associated with the chronic sorrow of long‐term spousal caregivers require specialized counseling approaches.     

Role of Surface Roughness in Hysteresis during Adhesive Elastic Contact

In experiments that involve contact with adhesion between two surfaces, as found in atomic force microscopy or nanoindentation, two distinct contact force (P) vs. indentation-depth (h) curves are often measured depending on whether the indenter moves towards or away from the sample. The origin of this hysteresis is not well understood and is often attributed to moisture, plasticity or viscoelasticity. Here we report experiments that show that hysteresis can exist in the absence of these effects, and that its magnitude depends on surface roughness. We develop a theoretical model in which the hysteresis appears as the result of a series of surface instabilities, in which the contact area grows or recedes by a finite amount. The model can be used to estimate material properties from contact experiments even when the measured P-h curves are not unique.
