Intra- and inter-subject variation in lower limb coordination during countermovement jumps in children and adults

The purpose of the present study was to investigate the coordination pattern and coordination variability (intra-subject and inter-subject) in children and adults during vertical countermovement jumps. Ten children (mean age: 11.5 ± 1.8 years) and ten adults (mean age: 26.1 ± 4.9 years) participated in the experiment. Lower body 3D-kinematics and kinetics from both legs were obtained during 9 vertical jumps of each subject. Coordination pattern and coordination variability of intra-limb and inter-limb coupling were established by modified vector coding and continuous relative phase. The adult group jumped higher and with less performance variability compared to the children. Group differences were mainly observed in the right–left foot coupling. The intra-subject coordination variability was higher in coupling of proximal segments in children compared to adults. No group differences were observed in inter-subject variability. Based on these results, it was concluded that the same movement solutions were available to both age groups, but the children were less able to consistently utilize the individually chosen coordination pattern. Thus, this ability appears to be developed through normal ontogenesis.     

低阶层者的系统合理化水平更高吗?——基于社会认知视角的考察

系统合理化理论曾提出,低阶层者比高阶层者具有更高的系统合理化水平,即更认可社会体系的合理性、更支持当前社会系统。但这一论断一直存在争议。研究引入社会认知视角,考察低阶层与高阶层者系统合理化水平的差异及其机制。两个分研究得到了共同的结果:(1)低阶层者的系统合理化水平显著低于高阶层者;(2)这一差异是通过贫富归因的中介作用实现的,低阶层者系统合理化水平较低是基于其更少地认为社会贫富差距是由个人内部因素所致;(3)这一中介作用会受到个体控制感水平的调节,当控制感较低时,上述中介作用成立;但当控制感较高时,低阶层会弥合与高阶层贫富归因的差异,中介模型不成立。这些结果支持并发展了系统合理化的认知途径解释和阶层社会认知理论这两个立足于社会认知的理论观点,显示了认知因素在此问题中的重要作用,构建了更整合的阶层—归因—合理化的逻辑,并考虑了其边界因素,对于了解低阶层者的社会心态及其形成机制,包括如何改变此状况,均有一定的现实启示意义。     

EARLY MODERN PROTESTANT VIRTUOSOS AND SCIENTISTS: SOME COMMENTS

The following essay is divided in three parts. First, while sharing in principle Harrison's hypothesis of an affinity between the sixteenth‐century Reformation and early modern science, it questions the connection between the latter and the Weberian “disenchantment of the world.” Second, it suggests a broader group of possible actors than that envisaged by Harrison in referring to virtuoso collectors and their cabinets of curiosities who are rather marginalized in Harrison's narrative. And third, it highlights (in agreement with Harrison) the physico‐theology of the second half of the seventeenth and the first half of the eighteenth century and beyond as an important temporary fusion of religion/theology and science at a time when the new science was still striving for social and religious respectability.     

Four types of fare evasion: A qualitative study from Melbourne,Australia

Fare evasion on public transport can reduce revenue by millions of dollars, undermining the financial viability of transit. However little research examines how public transport users think about fare evasion or attempts to understand why people fare evade. This paper presents the results of a program of qualitative research conducted in Melbourne, Australia to understand the attitudes toward and motivations behind fare evasion. A total of 67 people participated in face-to-face or online focus groups.Results established a spectrum of perceived circumstances where someone might travel without a valid ticket. ‘Fare evasion’ was considered to be at only one end of that spectrum. The degree of intent to evade was a critical factor explaining the severity of fare evasion from user perspectives. People’s attitudes toward fare evasion differed significantly; four key attitude segments were uncovered based on the attitudes and behaviours that group members tended to share. These included 1. ‘Fare evasion is wrong – the accidental evader’ who held strong views against fare evasion, 2. The ‘it’s not my fault’ evader who meant to pay but sometimes find themselves fare evading due to barriers to payment, 3. The ‘calculated risk-taker’ evader who deliberately fare evade if they think the reward outweighs risk and 4. ‘Career evaders’ who always fare evade. Attitudes, feelings and motivations for these segments are described and implications for revenue protection policy are discussed.     

Explaining Differences in Societal Levels of Happiness: Relative Standards, Need Fulfillment, Culture, and Evaluation Theory

This article addresses the question of which societal characteristics are likely to enhance subjective well-being. Empirical results bearing on four theories are presented: needs theory, goals theory, relative standards models, and cultural approaches. The theories are to a degree compatible, rather than completely contradictory. There is empirical support for each of the theories, but also there are data contradicting a simple formulation of each model, and no approach can by itself explain all of the extant findings. For both applied and theoretical reasons, it is imperative that we determine the types of societal characteristics that enhance subjective well-being. In this vein a model called Evaluation Theory is proposed, in which SWB depends on people's evaluations of self-relevant information. Attention is selective and therefore the factors that determine its focus are likely to influence evaluations of events. Thus, appraisals are likely to be influenced by chronically accessible information, which in turn is influenced by the person's needs, goals, and culture. Currently, salient information is seen as being a key to life satisfaction judgments. The present paper describes numerous limitations in current research suggesting studies that will allow more definitive theories to emerge.

The Virtual Universe, the Open Large Group, and Maturational Processes in the Future

The technology of the future will bring a new, world-wide, interactive but virtual social experience to our parlors and desktops in place of face-to-face relationships. Governments will stand or fall on the basis of electronically mediated communication with masses of people. Adventures in this new open large group context in the outer world, and the maturation of our inner selves may mirror as well as contribute to each other. Small group experience and group therapy, in particular, may play a vital role.     

All on the Same Side: Reflections on the Dialogue Between Science and Religion

The 'war' between religion and science is winding down, creating new opportunities for fruitful dialogue. The foundations of indirect religion-science dialogue, where the perspectives of the two disciplines illuminate some third subject, are not well established. A detailed comparison of the Roman Catholic bishops' dialogues and a similar program within the American Association for the Advancement of Science illustrates the variety in formalscience-religion interactions and reveals much about the promise, achievements, and limitations of different approaches. Success depends in large part on controlling the diversity of the dialogue group, choosing topics carefully, and adopting positive and cooperative attitudes.     

Freedom,Love, and Justice

This article starts from love as being a fundamental value, guiding modes of behaviour that establish a reliable framework and basis for the recognition of the rights and dignity of everyone in the community. The affirmation of justice and freedom based on love leads to corrective and transformative action in cases where life is threatened and rights are being violated. Drawing on the experience and witness of Martin Luther King Jr, the article underlines that love empowers the oppressed to stand up and becomes a moral imperative for change, against the background of the many forces promoting conflict and violence, division, and polarization. The power of love is a message to the world, to the powerful, and to the powerless – to all who long for a different reality from what we see in today’s world. This needs to be expressed in the quest for the unity of the church and the unity of humankind, serving the sustainability and unity of God’s creation.
