The present studies examined children's and adults' preferences for gender- or age-based categorization using similarity and inductive inference tasks. Four-year-olds, 6-year-olds, and adults looked at pictures of people and decided which of two was more like a target (similarity condition) or which shared a novel age- or gender-related property with the target (inference condition). Age or gender-based matches were possible. The results are consistent with previous findings that gender-based classification decreases with age. However, they also demonstrate that children use gender more for judging similarity than for making inferences about novel properties. Distinct patterns emerge from the two tasks: 6-year-olds and adults in both conditions categorize more by age than gender; 4-year-olds categorize by gender more than age in the similarity task, but by age more in the induction task. Only adults differentiated by property in the inference condition. These findings suggest that the salience of gender categories cannot entirely be attributed to their inductive potential. Gender has a salience beyond what would be predicted by its power for directing novel generalizations. 相似文献

盗窃未加盖公章和印鉴的无效空白支票,通过伪造公章和印鉴获取财产的,应定诈骗罪而不宜定盗窃罪。盗窃印鉴齐全的空白支票,自填数额、用途等,取款、转款或购买物资,其自填数额达到较大标准的,亦应按盗窃罪处理。流窜盗窃分子供述的盗窃或扒窃事实、情节与缴获的赃款赃物,与同案人的供述相一致,也应予以认定。行为人以非法占有有价凭证、有价证券、有价票证的财产为目的而取得了上述票证,但在持有过程中,行为人放弃了非法占有的故意或目的,未有领取款物而将票证归还原主或毁弃的,可按犯罪中止处理。盗窃他人合法占有、控制的自有物,应视为“他人”物,可以构成盗窃罪。普通物品在认定盗窃数额时,应根据其价格和价值特点,分别确定计算标准和办法。特殊商品中,假冒伪劣残次品的价值计算,应按其实际价值计算。在处理赃物时,对一些特殊性质的赃物,应采取特殊方法处理,不能按照处理一般赃物的办法处理。 相似文献

Summary. When evaluating potential interventions for cancer prevention, it is necessary to compare benefits and harms. With new study designs, new statistical approaches may be needed to facilitate this comparison. A case in point arose in a proposed genetic substudy of a randomized trial of tamoxifen versus placebo in asymptomatic women who were at high risk for breast cancer. Although the randomized trial showed that tamoxifen substantially reduced the risk of breast cancer, the harms from tamoxifen were serious and some were life threaten-ing. In hopes of finding a subset of women with inherited risk genes who derive greater bene-fits from tamoxifen, we proposed a nested case–control study to test some trial subjects for various genes and new statistical methods to extrapolate benefits and harms to the general population. An important design question is whether or not the study should target common low penetrance genes. Our calculations show that useful results are only likely with rare high penetrance genes. 相似文献

20世纪中国文学是伴随着20世纪中国社会的思想革命、政治革命、经济革命和文化革命,承接着具有两千多年深厚文化底蕴的中国古典文学传统发展起来的。由于这些现代革命的不彻底性,中国文化和文学中的古典审美思想和美学诉求并没有得到根本改造,而作为新的审美诉求的现代性质素始终没有得到健康持续的培育,这使得20世纪中国文学呈现出较浓的载道性、外向功利性和正剧色彩三大古典审美特征。 相似文献

Using a simple theoretical model and giving an empirical example it is investigated if it matters whether we use (monthly) averages or end-of-period (month) data in performing Granger-causality tests. It is shown that no major problems are to be expected if the two series are temporally aggregated in the same way, but non-trivial problems can occur if the two series have different kinds of temporal aggregation. 相似文献

Abstract Participation in rural development programs that organize members into local cooperative groups can alter the decision-making environment facing couples to reflect some of the negative consequences of childbearing. This study uses data from Nepal, collected through a combination of ethnographic and survey methods, to test the effects of participation in such a development program on fertility behavior. Results demonstrate that program participants are much more likely to use contraceptives to limit their fertility than are non-participants. The study provides empirical support for theories linking this type of institutional change to fertility and indicates a policy option that can allow some negative consequences of childbearing to affect couples' fertility decisions. 相似文献

The article examines some issues raised in Gavin and Wamboldt's (1992) recent study on the Family-of-Origin Scale (FOS) (Hovestadt, Anderson, Piercy, Cochran, & Fine, 1985). The discussion centers on unresolved concerns regarding the validity and utility of the FOS and on unsubstantiated and potentially misleading claims made in the Gavin and Wamboldt article. A case is made for conceptual and methodological precision in the study of family phenomena. 相似文献
