In human balance recovery, different strategies have been proposed with generally overlooked knee motions but extensive focus on the ankle, hip, and step strategies. It is not well understood whether maintaining balance is regulated at the lower “muscular–articular” level of coordinating segment joints or at a higher level of controlling whole body dynamics. Whether balance control is to minimize joint degrees of freedom (DOF) or utilize all the available DOF also remains unclear. This study aimed to use a realistic musculoskeletal human model to identify multiple balance recovery strategies with a single optimization criterion. Movements were driven by neural excitations (which activated muscle force generation) and were assumed to be symmetric. Balance recoveries were simulated with forward-inclined straight body postures as the initial conditions. When the position of the toes was fixed, balance was regained with virtually straight knees and mixed ankle/hip strategies. Under a severely perturbed condition, use of the forward hop strategy after releasing the fixed-toes constraint indicated spontaneous recruitment or suppression of DOF, which mimicked functions of optimally computed CNS commands in humans. The results also indicated that increase/decrease in the number of DOF depends on the imposed perturbation intensity and movement constraints.  相似文献

This study proposes a simple methodology to improve the quality of life of residents in nursing homes. In the experimental condition, an intervention based on the feeling of control, the technique of touching and “you are free to…” was implemented. Assessment of the residents’ appropriation of their personal space and their morale was made one month later. Data showed a significant improvement in both parameters in the experimental condition, whereas values remained stable in the control group, which did not receive the intervention.  相似文献

Religious freedom is a highly valued goal for many citizens and political leaders around the world, especially in Western‐oriented nations. Much ink has been spilled in defense of religious freedom and many have waxed eloquent about the virtues of promoting religious freedom. Most constitutions and other international documents around the world guarantee religious freedom even if those guarantees are sometimes honored in the breach. Why this focus on religious freedom is occurring and how it is being addressed are the focus of this article.  相似文献

This study measures the effect of regular worship attendance at age 17 on total years of schooling by age 25, using data from the National Longitudinal Survey of Youth 1997. Expanding on previous work, this study estimates differences in the impact of worship attendance by race and family income status using propensity score matching. Individuals who frequently attend religious services complete .69 more years of schooling than similar individuals who do not frequently attend services. There are significantly greater returns to attendance for low‐income youth and no significant difference in returns by religious affiliation. These findings suggest that religious observance provides greater benefits for low‐income individuals or perhaps provides resources high‐income individuals have access to elsewhere. Moreover, this study extends previous work by examining a more recent and nationally representative sample of youth and by using methods that allow for greater causal inference.  相似文献

Criticizing the misunderstanding and wrong explanation of Marx’s philosophical system made by recent Chinese textbooks on Marxist philosophy, the author argues that Marx’s philosophy has practical, economical-philosophical, and ontological dimensions and stresses on reconstructing Marx’s philosophical system through synthesizing the above three dimensions. This paper intends to set up a new outline of Marx’s philosophical system, in terms of the following four concepts—thing, value, time, and freedom.

This paper addresses the question of what we can legitimately say about things in themselves in Kant's critical doctrine. Many Kant scholars believe that Kant allows that things in themselves can be characterized through the unschematized or ‘pure’ concepts of our understanding such as ‘substance’ or ‘causality’. However, I show that on Kant's view things in themselves do not conform to the unschematized categories (given their standard discursive meaning): the pure categories, like space and time, are merely subjective forms of finite, discursive cognition. I then examine what this interpretation might entail for central aspects of Kant's system such as his doctrine of noumenal freedom.  相似文献

Abstract?

The election of Ieronymos as archbishop of Athens took place at a critical moment for the Orthodox Church of Greece (OCG). On the one hand, the social credibility of religious bureaucracy was waning. On the other, a fundamentalist faction within the Synod was essentially questioning his authority. In order to confront these problems, Ieronymos found the necessary social and religious legitimisation via the partial democratisation of the administrative function of the OCG as well as the restoration of its relations with the Patriarchate of Constantinople (the Ecumenical Patriarchate). The decoding of this intraecclesial strategy, starting from his election in February 2008 until October 2009, is the topic of the present article.  相似文献

Abstract

According to Alasdair MacIntyre, Kierkegaard fails to provide rational reasons to choose between an aesthetic lifestyle and an ethical lifestyle. This claim subsequently initiated a significant discussion that investigated whether one can rationally choose between ethics and aesthetics. I will be challenging both MacIntyre’s criticism and in large part the basis of the subsequent discussion by arguing that there is no choice between aesthetics and ethics at all. Specifically, I will be arguing that in Either/Or Kierkegaard demonstrates that the essence of human existence is the freedom to make choices. Given that the ethical is the existential reality of having to make choices, human existence is therefore necessarily ethical. This conclusion follows from my thesis that the essential difference between the aesthete and the ethicist in Either/Or is their opposing views on whether choices are necessary elements of experience.  相似文献
