The Possibility of Meaning in Human Evolution

Science undermines the certitude of non-naturalistic answers to the question of whether human life has meaning. I explore whether evolution can provide a naturalistic basis for existential meaning. Using the work of philosopher Daniel Dennett and scientist Ursula Goodenough, I argue that evolution is the locus of the possibility of meaning because it has produced intentionality, the matrix of consciousness. I conclude that the question of the meaning of human life is an existentialist one: existential meaning is a product of the individual and collective tasks human beings undertake.

用《教师教学效果评价问卷(学生版)》问卷对高校181名教师的教学效果进行调查,用多层次分析法对影响教师教学效果的教师背景变量:教师性别、年龄、学历、职称、所教专业、年级、班级大小以及课程类别对教师教学效果影响程度进行分析,目的在于通过用多层分析法更合理分析教师背景变量对教学效果产生的影响,为客观比较教师教学效果之间的差异提供依据。研究结果表明:(1)多层次分析法得到比传统回归分析和方差分析更合理更准确的结果;(2)教师背景变量教师中性别、学历、专业以及所教班级的大小对于教师教学效果评价效果没有显著影响;(3)教师职称、年龄、所教学生年级、课程类别对教师的教学效果有显著影响;(4)所考察的教师水平背景变量对教学效果各个维度教师水平总变异的解释率介于3351%-4278%之间。     

John Bridges's Tools of Persuasion: Prescription,Dispensation, and Early Christianity in A Defence of the Government Established(1587)

Abstract

Prayer was central to the worship and everyday life of both clergy and laity in late medieval England. This paper explores how far domestic prayer changed in the early modern period. After a brief historiographical and methodological survey, it is suggested that in the period 1540-1640, Protestant clergy were anxious for the laity to acquire the ‘gift’ of composing their own prayers for use in family worship and closet, though they did countenance the use of suitably Protestant set forms as a temporary ‘crutch.’ However, many parishioners apparently preferred to persist with prepared forms, some composed by clergy, others by lay authors with rather different emphases to their pastors. The radicalism of many who ‘prayed with the Spirit’ in the 1640s and 1650s produced some caution among moderate clergy on the wisdom of encouraging parishioners to ‘conceive’ their own prayers. This was one reason why the period 1660-1720 witnessed an Indian summer of publication of set forms by both clergy and laity.     

Hierarchical Model of Generalized and Specific Vulnerabilities in Anxiety

This study evaluated a theoretical hierarchical relationship among the general anxiety vulnerability variable of neuroticism, the specific vulnerability variables of anxiety sensitivity and intolerance of uncertainty, and variables reflecting specific anxiety foci including panic symptoms, health anxiety, obsessive-compulsive symptoms and generalized anxiety/worry. Questionnaires assessing these variables were administered to a non-clinical sample of 91 first-year psychology students (64.8% women). Path analysis results were highly consistent with the hypothesized hierarchical model. Neuroticism was found to have a significant direct effect on both anxiety sensitivity and intolerance of uncertainty. Both neuroticism and anxiety sensitivity had direct significant effects on panic symptoms, neuroticism and intolerance of uncertainty both made significant direct contributions to the prediction of worry, and neuroticism made a significant direct contribution to the prediction of obsessive-compulsive symptoms. Contrary to the hypothesized model, anxiety sensitivity but not neuroticism uniquely predicted health anxiety. The results of this study provide initial empirical evidence for a hierarchical relationship among general and specific vulnerabilities, and specific anxiety manifestations.     

Does visual working memory work as a few fixed slots?

The present study investigated whether visual working memory (VWM) functions as a few (about 3?～ 4) fixed slots by examining how the distribution of VWM is adjusted. Adopting a change-detection paradigm, we required subjects to memorize four items, one of which was prioritized. If VWM functions as 3?～?4 slots, allocating multiple slots to the prioritized item would leave no slot for some other items; consequently no information would be stored for them, leading to a substantial decrease in change-detection performance no matter whether small or large changes occurred. The result showed that small changes on the unfavoured items were detected less accurately, indicating that more VWM was allocated to the favoured item. Yet meanwhile large changes that occurred on those unfavoured items could still be detected as well as those on the favoured one, indicating that each of them was still stored to some extent rather than completely discarded. The results suggested that VWM may not work as 3?～?4 fixed slots. Possible mechanisms were discussed based on the present results, including a modified slot model with more available slots, a continuous resource model, and a hierarchical model that assumes storage of ensemble information in addition to the information of individual items.     

Spouses' Cortisol Associations and Moderators: Testing Physiological Synchrony and Connectedness in Everyday Life

In this study, associations were examined between cortisol levels of wives and husbands in 47 heterosexual married couples. Both partners' salivary cortisol levels were measured at the same moments seven times a day on 2 typical weekdays. After accounting for the effects of the diurnal rhythm of cortisol and relevant control variables, dyadic hierarchical linear modeling indicated significant positive linkages between partners' cortisol levels, consistent with the hypothesized within‐couple physiological synchrony. Variables reflecting more (spousal presence) or less connectedness (loneliness, being alone) were also collected at the time of each cortisol sample. Results indicated that husbands' cortisol levels were higher at moments they reported feeling lonelier and lower at moments they were in the presence of their spouse. Wives' cortisol levels were higher at moments they were alone. In addition, wife–husband cortisol synchrony was stronger for husbands who spent relatively more time with their spouse across the study period—even after accounting for time spent with others in general. These findings suggest that marital partners evidence positive within‐couple cortisol associations, and that connectedness (particularly physical closeness) may underpin spouses' physiological synchrony.     

Peer Substance Use and Homelessness Predicting Substance Abuse from Adolescence Through Early Adulthood

Adolescents who experience homelessness are at higher risk for abusing substances, and for being exposed to substance-using peers. The current study used a longitudinal design to track substance abuse, affiliation with substance-using peers, and episodes of homelessness among a sample of 223 adolescents who were housed at the baseline data collection and 148 adolescents who were housed at baseline. Participants were interviewed at six waves over 6.5 years, covering an age range from 13 to 25. Many participants experienced a recurrence of homelessness during follow-up, with 64.6 % of the baseline homeless group and 22.6 % of the baseline housed group reporting an additional episode of homelessness. Both alcohol abuse and other drug abuse symptoms showed an increase in adolescence followed by slowing in early adulthood. Recent homelessness and friend alcohol use predicted alcohol abuse symptoms, and the strength of the influence of friend use decreased over time. Recent homelessness and friend drug use predicted other drug abuse symptoms. Duration of the initial episode of adolescent homelessness showed no influence on substance abuse over time, or the effects of other predictors, highlighting the importance of conceptualizing the experience of homelessness as a recent stressor rather than an enduring personal characteristic.     

Philosophy and Chinese Philosophy

Philosophy can be divided into two systems, i.e. the vertical and the horizontal. Characterized with the creation of spirit and the logical evolution of concepts, the vertical system expresses historical reflections on the achievements of human culture. Meanwhile, the horizontal system focuses on the analysis of cognitive activities to explore the nature of subject and object, the elements of knowledge, and the basis of its certainty. Chinese philosophers, such as Hu Shih, Fung Yulan, Zhang Dainian, Mou Zongsan and Zhang Shiying, have previously explored the various definitions of philosophy. Their explorations manifest the internationalization of Chinese philosophy during different eras. This paper defines philosophy as human beings’ awareness of their environment and systematical reflections on their activities and ensuing consequences. As part of world philosophy, Chinese philosophy encapsulates the essence of Chinese culture, as the thinking method of Chinese people, and as a set of thought systems possessing a unique style.     

Information-Hierarchical Organization of Natural Systems I: The Information-Physical Principle

The mathematical notion of information characterizing system organization as such has been developed. The information-physical principle, which characterizes an information exchange in natural hierarchical systems and has been confirmed by its numerous applications, is laid down. It is shown to be based on the ancient “matter–measure–information” concept of physical world structure and talked about in the Hermes Trismegistus's will.
