Science and the Catholic church are both conservative, slow-to-change institutions. However, science has institutionalized procedures that ensure that ample amounts of criticism of currently accepted theories and methodologies will always be present. This arrangement of continuous conjectures and refutation in science ensures often slow but steady change. Because supporters often think of religions as trafficking in timeless truths, criticism of church beliefs and practices (even when intended to stimulate reflection and improvement) is frequently seen as being disloyal to the institution. Because of the growing crises caused by world overpopulation, I argue that the Catholic church's opposition to all artificial methods of birth control now lacks whatever moral force it might have had when originally promulgated. By highlighting theological perspectives that might be appropriate for the ecological realities of the 21st century, I hope the church will see the wisdom of reevaluating many of its positions in the light of rapidly approaching ecological imperatives. 相似文献

Estimates of temporal proximity (sometimes called time-to-collision) from random-dot flow patterns are shown to be based upon retinal speed, rather than upon changes in dot density. Neither the spatial nor the temporal gradient of motion is essential to the task, but estimates can be made from either alone. Performance is unaffected by the addition of rotational motion, suggesting that observers axe capable of extracting the radial component of motion, which contains all the relevant information, from complex stimuli. 相似文献

The study included 17 patients, 12 women and 5 men, with a recurrent symptom complex involving chest pain and dyspnoea characterized
by inability to get a full breath. Some attacks had subsided spontaneously. Others had lasted hours or days. When examined
by fluoroscopy during an attack, each subject was found to have a nearly maximally contracted (flat) diaphragm. In some of
them the attack was promptly interrupted by a small intravenous injection of sodium amytal. In others it could be aborted
by a conscious effort at full expiration. The syndrome associated with diaphragmatic spasm is discussed in comparison with
other noncardiac sources of chest pain and dyspnoea. 相似文献

Five experiments reexamined color aftereffects contingent on the semantic properties of text (Allan, Siegel, Collins, & MacQueen, 1989). The influence of different assessment techniques and the effect of eye movements and overlapping contour information on the induction of color aftereffects by word and nonword letter strings were determined. Experiment 1 showed that no aftereffect was found when a traditional method of assessing color aftereffects was used. Experiments 2 and 4 demonstrated color aftereffects forboth words and nonwords, but only when subjects fixated the same locus during induction and testing and only when assessed with the technique described by Allan et al. (1989). If, however, eye movements were made during induction, no color aftereffect was obtained (Experiment 3). Induction to nontext patterns with properties similar to those of text but with fewer overlapping contours resulted in a strong color aftereffect (Experiment 5). These results suggest that the color aftereffect contingent on text is very weak and is not dependent on semantic factors, but that it is a product of induction to local color and orientation information. 相似文献
