A part of relativistic dynamics is axiomatized by simple and purely geometrical axioms formulated within first-order logic. A geometrical proof of the formula connecting relativistic and rest masses of bodies is presented, leading up to a geometric explanation of Einstein's famous E = mc² . The connection of our geometrical axioms and the usual axioms on the conservation of mass, momentum and four-momentum is also investigated.

Individual health savings accounts are an important part of the current basic medical insurance system for urban workers in China. Since 1998 when the system of personal medical insurance accounts was first implemented, there has been considerable controversy over its function and significance within different social communities. This paper analyzes the main problems in the practical implementation of individual medical insurance accounts and discusses the social and cultural foundations for the establishment of family health savings accounts from the perspective of (...) Chinese Confucian familism. Accordingly, it addresses the direction of the reform and the development of the current system of individual health insurance accounts in China. (shrink)

Injury to the central or peripheral nervous system is often associated with persistent pain. After ischemic injury to the spinal cord, rats develop severe mechanical allodynia-like symptoms, expressed as a pain-like response to innocuous stimuli. In its short-lasting phase the allodynia can be relieved with the [gamma]-aminobutyric acid (GABA)-B receptor agonist baclofen, which also reverses the hyperexcitability of dorsal horn interneurons to mechanical stimuli. Furthermore, there is a reduction in GABA immunoreactivity in the dorsal horn of allodynic rats. Clinical neuropathic (...) pain of peripheral and central origin often cannot be relieved by opiates at doses that do not cause side effects. The loss of sensitivity to opiates may be associated with the up-regulation of endogenous antiopioid substances, such as the neuropeptide cholecystokinin (CCK). CCK and its receptor (CCK-R) protein is normally not detectable in rat dorsal root ganglion cells. After peripheral nerve section, both CCK and CCK-R are up-regulated in the dorsal root ganglia. Furthermore, CI 988, an antagonist of the CCK-B receptor, chronically coadministered with morphine, reduces autotomy, a behavior that may be a sign of neuropathic pain following peripheral nerve section. Thus, opiate insensitivity may be due to the release of CCK from injured primary afferents. Similarly, in the chronic phase of the spinal ischemic model of central pain, the allodynia-like symptom is not relieved by systemic morphine, but is significantly reversed by the CCK-B antagonist. Consequently, up-regulation of CCK and CCK-R in the CNS may also underlie opiate drug insensitivity following CNS injury. Thus, dysfunction of central inhibition involving GABA and endogenous opioids may be a factor underlying the development of sensory abnormalities and/or pain following injury to neural tissue.

Some Trouble with Cows b.Mahasweta Devi and the Literary Exposure of Violence V.The Question of a Christian Perspective on the Hindu Treatment of Violence and Religion: Are Victims Necessary? Some Presuppositions: • The following reflections, complex as they are, are governed by a reluctance to simplify Hindu teaching. I seek to avoid the view that the Hindu traditions had only one view of violence and nonviolence. • I use the term "Hindu" loosely and as a shorthand, without claiming that there is a single Hindu tradition, or a single creed shared by all Hindus, or a single attitude toward violence. But neither do I claim that there are simply many traditions without any common elements which justify the appellation "Hindu." • I am reluctant to idealize the Hindu traditions as if nonviolence must necessarily be taken as the epitome ofHindu thought. India's traditions are complex, and require complex treatment. • A serious artificiality of this paper is that I treat Hinduism without simultaneously lookinginto Buddhist andJain materials, though both were traditions with important and enduring commitments to nonviolence. Particularly with respect to the renunciant, marginal components of traditions, one ought not to make overly neat or decisive distinctions Violence and Nonviolence in Hindu Religious Traditions 1 1 1 between the Hindu, Buddhist, and Jain theories and practices related to violence and nonviolence. • I attempt to give preference to indigenous discussions ofissues related to violence and nonviolence; the context and mode of thinking are important, notjust the conclusions drawn. I therefore avoid simply mining Hindu texts for an answer to a contemporary question, "What is the Hindu attitude toward violence and nonviolence?" • In most ofwhat follows we must distinguish contexts where "violence" indicates "physical action which causes pain to some living being," from contexts where "violence" indicates "an intention, rooted in anger or malice, to hurt someone." I use the word "violence" for both in order to highlight the complex issues of distinction involved. In considering the Sanskrit formulations, one likewise has to distinguish himsa as "causing pain" from himsa as "intending to harm." • It is often difficult to date ancient texts, and even when one narrows down a date—within 200-300 years—its significance still depends on other, often equally broadly stated dates. Nevertheless, I do offer dates throughout, as summarized here: •ancient Vedic sacrificial practices, from before 1200 BCE •Vedic ritual analyses and reformulations of sacrifices as ritualized acts, in the Brahmanas, from after 1000 BCE •the Upanishadic exploration of the deeper meanings of ritual and interiorized alternatives to ritual, from after 900 BCE •the Buddha, c. 500 BCE •key texts in the theorization of royal power, The Laws of Manu (beginning of Common Era) and Arthashastra (c. 150 CE) •the Tamil wisdom text Tirukkural (100 CE) •Goddess texts as evidenced in Sanskrit formulations, from after 500 CE...

There are good reasons for envisioning a global discourse about God, premised necessarily agreed upon perfections considered to be by definition proper to God, and for thinking through the implications of our understanding of God for morality. Philosophically, it makes sense to hold that claims about omnipotence, omniscience, and other superlative perfections are indeed maximal, and define “God” wherever the terminology of divine persons is taken up. Religiously too, it makes sense to assert that a deity possessed of perfections is (...) not just the deity of one’s own tribe or religion, but also the deity of the whole world, whether acknowledged as such or not. This essay delves into the larger set of rich complexities by three moves. First, I look into a single extended historical case of the extension of the discourse about God beyond the Christian West, the discourse on God proffered by Western Jesuit missionaries in India from the sixteenth to twentieth centuries. Second, I place next to that Jesuit learning the instance of a famed Hindu theologian’s discourse on God, God’s perfections, and their moral implications. Third, I briefly step back and assess the dangers and fruitful prospects inherent in thinking about God and morality in an interreligious context. (shrink)

ABSTRACTFilm clips are widely used in emotion research due to their relatively high ecological validity. Although researchers have established various film clip sets for different cultures, the few that exist related to Chinese culture do not adequately address positive emotions. The main purposes of the present study were to establish a standardised database of Chinese emotional film clips that could elicit more categories of reported positive emotions compared to the existing databases and to expand the available film clips that can (...) be used as neutral materials. Two experiments were conducted to construct the database. In experiment 1, 111 film clips were selected from more than one thousand Chinese movies for preliminary screening. After 315 participants viewed and evaluated these film clips, 39 excerpts were selected for further validation. In experiment 2, 147 participants watched and rated these 39 film clips, as well as another 8 excerpts chosen from the existing databases, to compare their validit... (shrink)

The microstructures of cryogenically ball-milled Cu were investigated by high-resolution electron microscopy. It was found that the grain-size reduction is a dislocation-controlled continuous process which consists of the formation of small-angle grain boundaries , a gradual increase in misorientations as a result of accumulation of more dislocations and, finally, the formation of large-angle GBs. The GBs were generally curved, wavy or faceted, and heavily strained, which are typical characteristics of nanostructured materials. In addition, extrinsic dislocations were found in many GBs, (...) indicating that most are in a high-energy non-equilibrium configuration, which is consistent with observations in equal-channel angular pressing processed Cu, Ni, and Al-Mg, repetitive corrugation and straightening processed Cu and room-temperature ball-milled Cu. These results support a still-disputed concept that GBs in nanostructured metals processed by severe plastic deformation are mostly in non-equilibrium states. (shrink)
