Jerusalem is at the centre of Christian culture – the place of the Lord's Passion and Resurrection and the place of Pentecost – and the image of Jerusalem is fundamental to any Christian vision of the Church and the Kingdom. There was an earthly city and one in heaven; and since the temple was inseparable from the city, temple imagery – the Garden of Eden, the Holy Wisdom, the Messiah – appears in Christian hymns about Jerusalem. In the centuries preceding the advent of Christianity, both city and temple had become corrupt, so when Jesus cleansed the temple and prophesied the destruction of the city, many people would have applauded him. The harlot city that burned in the Book of Revelation was Jerusalem, and when the emperor Constantine built the Church of the Resurrection in Jerusalem, he was building a Christian temple, replacing not the one destroyed in 70 CE, but the original temple of Solomon.     

Utility of extension of functional equations—when possible

Jean-Claude Falmagne observed in 1981 [On a recurrent misuse of classical functional equation result. Journal of Mathematical Psychology, 23, 190-193] that, even under regularity assumptions, not all solutions of the functional equation k(s+t)=k(s)+k(t), important in many fields, also in the theory of choice, are of the form k(s)=Cs. This is certainly so when the domain of the equation (the set of (s,t) for which the equation is satisfied) is finite. We mention an example showing that this can happen even on some infinite, open, connected sets (open regions). The more general equations k(s+t)=?(s)+n(t) and k(s+t)=m(s)n(t), called Pexider equations, have been completely solved on R². In case they are assumed valid only on an open region, they have been extended to R² and solved that way (the latter if k is not constant). In this paper their common generalization

k(s+t)=?(s)+m(s)n(t)     

Introduction: W. E. B. Du Bois: Religion and Social Inequality

W.E.B. Du Bois understood the critical role religion plays in power inequities in the, world. He was very acquainted with how it is used as a tool to exclude and subordinate human beings and yet, at the same time, serve as a source of refuge. This special issue of the Journal for the Scientific Study of Religion is a collection of articles that examines religion and social inequality from a variety of different angles with a Du Boisian lens. When we focus our lens on religion and social inequality, we are highlighting the ways in which religion plays a part in the unequal distribution of power across social groups in society. This special issue focuses on how religion impacts social life and the way individuals and groups embody or struggle to reclaim their agency within a context of silent oppression at times and not-so-silent oppression at others times at the personal-, group-, and global levels.     

在亮度对比和颜色对比下立体视知觉的定量研究

研究了在亮度对比与等亮度颜色对比的条件下,受试者分辨随机点阵立体图对的立体视敏度（最小视差）．结果表明：（１）在亮度对比条件下,立体视敏度随对比度的增加而增加,１０％的对比度即可引起立体视知觉,对比度大于３０％时达到饱和;（２）在亮度对比与等亮度颜色对比两种不同的条件下,受试者的立体视敏度不存在有统计学意义的差异;（３）当双眼分别接受不同颜色的等亮度立体图刺激时,与亮度对比条件相比,受试者的立体视敏度无明显差异;（４）当受试者双眼分别接受由亮度对比和颜色对比形成的立体图刺激时,只有当颜色对比图中图形与背景间的对比度超过等亮度值３８％以上时,才能形成立体视知觉．以上结果提示,大、小细胞系统（包括斑点系统与斑点间系统）均参与立体视知觉信息的传递．     

Partial reinforcement and autoshaping of the pigeon's key-peck behavior

Pigeons were exposed to continuous and partial reinforcement (25%) schedules in an autoshaping procedure. The number of trials and/or pairings per session were equated across two factorial group sets and all groups were trained for a fixed total number of acquisition trials (192). When acquisition was analyzed as a function of reinforcements delivered, the groups receiving fewer number of trials per session acquired the response faster, independently of the percentage of reinforced trials. Moreover, the number of reinforcements to satisfy an acquisition criterion was a monotonic function of the number of trials per session but not of the schedule. The results are discussed in relation to the neocontinuity and the scalar expectancy theories.     

Individual differences in preschool children's knowledge of superordinate categories

The present study assesses intensional knowledge of superordinate categories in preschool children. This assessment is part of a larger programmatic research effort aimed at the development of a cognitive preschool screening test to detect learning problems prior to their manifestation in school failure. Necessary prerequisites for including intensional superordinate category knowledge as a potential component of this screening test are addressed: (a) Are there substantial variations in this knowledge across preschool children? (b) Can the knowledge be measured reliably using game-like picture tasks? (c) Do individual differences in this knowledge relate to the child's current level of intellectual functioning? An underlying assumption for the development of this screening test is that assessing gradually emerging abstract knowledge that develops through active, ongoing processing is more likely to predict learning problems than assessing knowledge that develops through rote associative learning. Consistent with this approach was the prediction that one component of intension, knowledge of differences, would be a better predictor of current functioning than knowledge of similarities. The data support this contention. Although both knowledge of similarities and differences was stable within an individual, variable among individuals and highly correlated with each other, only knowledge of differences related to the child's concurrent level of intellectual functioning.     

The early resumption of employment by mothers: Implications for parent-infant interaction

Home observations of mother-father-infant interaction and mother-infant interaction were contrasted in middle-class families in which the mother was employed or a full-time caregiver. First-born infants and their parents were observed at 3 months. The results indicate that when mother, father, and infant were together parents in the single wage-earner families provided more tactile stimulation to their babies; fathers in single wage-earner families tended to interact more with their infants than did mothers, while in dual wage-earner families mothers tended to interact more than fathers; and fathers in single wage-earner families exceeded fathers in dual wage-earner families in interactions with their infants. By contrast, mothers in the two groups showed very little difference in their interactions with their babies. No significant differences were found for maternal behavior in the three-person observation, and a single behavior differentiated between the groups in the mother-baby observation, with homemaker mothers more often making visual contact with their babies. The implications of these findings are discussed, both with respect to further research, and with regards to the development of children of employed mothers.     

HBeAg阳性慢性乙型肝炎抗病毒治疗药物的比较

抗病毒治疗是慢性乙型肝炎治疗的关键。目前抗乙型肝炎病毒（HBV）药物主要有两大类,本文从抗病毒治疗的适应症、禁忌症、治疗效果、耐药性、依从性和治疗费用等方面对现有抗HBV药物进行了比较和分析,认为在选择抗HBV药物时,应遵循规范化与个体化相结合的原则,在患者能承受的费用范围内,尽量选择抗病毒作用强、耐药率低、耐受性良好的药物。     

Gerstmann syndrome without aphasia: a longitudinal study

A case of "pure" and complete Gerstmann syndrome resulting from a focal vascular lesion in the posterior parietal area of the left hemisphere and not associated with aphasic disorder or general mental impairment is described. The initial symptom presentation of this patient supported the concept of the autonomous nature of the Gerstmann aggregate but longitudinal findings suggested that these symptoms did not in fact represent a coherent syndrome.
