David Thorne's (2010) article, “The Identities Hidden In The Matching Laws, And Their Uses” performs a valuable service in pointing out alternative expressions of matching. However, some identities tend to obscure rather than illuminate empirical relationships. Three such problematic instances are discussed: interresponse time as a function of interval and ratio schedule parameters; probability equality as implying rate matching; the apparent simplicity of probabilistic functions, as opposed to response rate functions, of reinforcement rate.  相似文献

Luo Congyan put forward the idea that benevolence is the substance while righteousness is its function, which placed the intrinsic value of human beings on a more fundamental position and affirmed the unity of benevolent principle and universal norms from the perspective of the relationship between substance and function. The unity of benevolence and righteousness involves the connection between value and norms, and the latter relate to the relationship between morality and law in the broader sense. On the basis of the idea of using both benevolence and righteousness, Luo Congyan examined the relationship between morality and law. Corresponding to the emphasis on the role of both law and political power, Luo Congyan concerned himself with how to establish rational interpersonal relationships in various ways. Furthermore, Luo Congyan emphasized the significance of behavior in everyday life, while he affirmed that the universal principle should be followed. In this way, he developed the earlier Confucian thought. Translated from Studies in Ethics by Xiao Mo  相似文献

长期以来,对心衰和心衰机制的认识一直存在争议,所以心衰的治疗一直是国内外心血管领域中的一个挑战.为了澄清心衰机制的内涵,本文用弗兰克-斯塔灵定律以及能量守恒定律作为重建心脏理论以及心衰机制的依据,论证了心脏的做功是从动能向势能,又从势能向动能的转换过程.并根据临床事实等来证实心脏舒张是在作功,与收缩期作功是等同的.没有心脏的舒张就没有心脏的收缩,心脏功能下降实际上是舒张与收缩功能同时的下降.不存在有收缩功能正常的舒张功能下降.心功能的判定标准不能采用射血分数,而应该采取能量消耗的定量方法来测定.  相似文献

《管子》认为,治理国家既要采用怀柔政策,主张为政者"先之以德",通过整饬四维来形成良好的社会风尚;又强调"法不可不审",主张通过严刑峻法来树立君主的权威,赏罚严明,使人们严格遵守各项法令制度,坚持"且怀且威",礼法并重,其思想对现代社会有很好的启迪意义。  相似文献

ABSTRACT

An article on canon law resources on the World Wide Web is sorely needed. Using Copernic Pro software, several search engines were consulted and the results correlated. The kinds of websites selected for this article include general websites on canon law, limited area search engines useful to the canonical researcher, official church organizations, laws of the Christian churches, schools, institutions, societies, encyclopedias, the history of canon law, professional assistance in canon law, foreign language sites, and subjects in canon law (e.g., marriage, abortion, and women's ordination). The information available varies widely, and includes church documents, review articles, bibliographies, discussion lists, databases, and commercial sites.  相似文献

Lutheran theological discussions over the morality of same‐sex sexuality not only raise “ethical” questions, but point to deeper interpretive tensions that arise when resources of the tradition are interpreted in new contexts. Responding to these debates, in this article I propose that Luther's application of the law to challenging ethical situations provides a historically situated hermeneutic that can redirect theological discussions on same‐sex sexuality. Drawing upon feminist Lutheran and queer theological work, I consider how we may reengage with Luther in a way that is both faithful to his commitments, and also takes queer people seriously as moral subjects.  相似文献

Rotations are fundamental to motor control, not only for orienting to stimuli but also in the joint articulations that underlie translational movements. Studying three-dimensional (3-D) rotations of the simplest joint system, the eye, has provided general insights into the neural control of movement. First, in selecting one 3-D eye orientation for each two-dimensional (2-D) gaze direction, the oculomotor system generates a behavior called Listing's law that constrains eye position to a 2-D plane, Listing's plane. This selection is made internally by an inverse kinematic transformation called the Listing's law operator. Second, the oculomotor system incorporates the inherent multiplicative relationship between rotational velocity and position to generate the 3-D movement and position commands required by Listing's law. Finally, the coordinate systems for these commands appear to align with Listing's plane rather than with anatomic structures. Recent investigations have revealed similar behavioral constraints in the orientations of the head and arm, suggesting that the neural mechanisms for Listing's law may have analogues in many motor systems.  相似文献

Three experiments are reported, investigating the effects of using 1 or 2 hands when making convergent low index of difficulty (ID) and visually controlled movements (2 hands meeting together). The experiments involved movements in four different cases—a probe held in the right hand and moved to a target held in the stationary left hand, vice versa of this arrangement, both hands moving with the probe in the right hand and target in the left hand, and vice-versa of this arrangement. Experiments were the standard Fitts’ paradigm, moving a pin into a hole and a low-ID task. In Fitts’ task, 2-hand movements were faster than 1 hand only at higher IDs; this was also the case in the pin-to-hole transfer task and the movement times were lower when the pin was held in the preferred hand. Movements made with low ID showed a small effect of 1- or 2-handed movements, with the effective amplitude of the movement being reduced by about 20% when 2 hands were used.  相似文献
