微信红包的特性决定了其属于刑法上的财物。而依据微信红包用户协议及运行机制,则可以认为"盗抢"前的微信红包由发红包者占有及所有,财付通公司扮演占有辅助人身份,"盗抢"后的微信红包由"盗抢"者占有及所有,且案件被害人应当是发红包者。案件中单纯潜伏入群"盗抢"微信红包行为符合秘密窃取他人财物,且数额较大,应当构成盗窃罪。但若行为人冒充他人身份"盗抢"微信红包,可能构成诈骗罪。 相似文献

不知从什么时候起，网络红包火了起来，每逢节假日，总会看到QQ群里红包满天飞的场景。尽管有时候我也抢红包，但从理性角度分析，我是不支持网络红包的。我第一次意识到网络红包的强大诱惑力，是在一个群里。一个和我年纪相仿的学生，正逼一个人发红包，那人开玩笑地来了一句：“你叫我一声‘爹’我就发。” 相似文献

Congruence between Mothers' and Fathers' Differential Treatment of Siblings: Links with Family Relations and Children's Well-Being 总被引：2，自引：1，他引：2

We studied patterns of mothers' and fathers' differential treatment of firstborn (average age 10.5 years) and secondborn (average age 8 years) school-age siblings, and we examined the links between parents' differential treatment and children's well-being and dyadic family relationships. Mothers, fathers, and both siblings in 110 families were interviewed in their homes. For each dimension of parental behavior that we assessed (i.e., differential affection and discipline) we created groups of families that reflected mothers' and fathers' levels of differential treatment (e.g., discipline the firstborn more, equal treatment, discipline the secondborn more). Although we detected substantial correspondence between the 2 parents' differential treatment, we found a sizable group of families in which parents' reports were incongruent (i.e., 1 parent reported equal and the other differential treatment). Parental patterns were linked to differences between the siblings' well-being and both sibling and parent-child relationships, with younger siblings exhibiting greater vulnerability to differential treatment. Incongruence in differential warmth was associated with marital distress. 相似文献

Do young boys and girls understand what leads to academic success (e.g., talent, effort, good teaching, luck) in the same way? Do young girls and boys have equivalent perceptions of their academic competence? Are these beliefs engendered in the same way across sociocultural contexts? In a cross-cultural study of over 3,000 children in grades 2 to 6, ages 7.2 to 13.6, we discovered that boys and girls around the world have very similar ideas about what generally leads to academic success. Moreover, in the few contexts where boys' and girls' academic performances were equal, their beliefs were also equal. However, when girls outperformed boys, their beliefs in their own talent were no greater than boys' beliefs, even though they did have stronger beliefs than boys in other facets of their achievement potential (e.g., putting forth effort, being lucky, getting their teacher's help). Our findings support the generally close correspondence between children's achievement and their competence-related beliefs, with the exception that young girls appear to specifically discount their talent. The effects held regardless of the children's achievement, intelligence, or age (approximately 8 to 13 years). Girls were more biased in some contexts than in others, however, suggesting that competence-related biases are rooted in culture-specific aspects of school settings. 相似文献

哈耶克的货币理论包括早年的中性货币学说和晚期的货币非国有化学说。中性货币学说强调货币数量的变化无论是否引起一般物价水平的变动,只要相对价格发生变动,就会影响生产的数量和方向,这一理论对我国在保持物价水平基本稳定的条件下,进行产业结构调整具有指导作用。哈耶克提出货币非国有化的主张,目的是要维护市场自由竞争秩序。 相似文献

传统的遗传算法有2个严重的缺点,即不能有效地消除过早收敛现象以及在进化后期搜索效率较低。模拟退火算法是基于金属退火的机理而建立起来的1种全局最优化方法,它能够以随机搜索技术从概率的意义上找到目标函数的全局最小点。将遗传算法与模拟退火算法相结合,提出模拟退火遗传算法。实验结果表明,该算法在性能上有较大的改善。 相似文献

Pigeons were trained on two independent tasks. One involved red and yellow hues, the other involved blue and green hues. For half of the birds, the two tasks were the same (i.e., both tasks were either matching-to-sample, or oddity-from-sample). For the remaining birds, the two tasks were different (i.e., one task was matching-to-sample; the other task was oddity-from-sample). Following acquisition, the pigeons were exposed to test trials on which either the correct or the incorrect comparison hue was replaced with one of the hues from the other task. On yellow-sample trials and on green-sample trials, the pigeons performed as if they had a common code for yellow and green. When there was one comparison available that was appropriate to the “yellow/green” code, performance remained high; but when either both comparisons or neither comparison was appropriate to the “yellow/green” code, performance dropped. The pigeons also tended to code red samples as green and to code blue samples as yellow. The results indicate that pigeons can categorically code colors under conditions that rule out a failure to discriminate among the colors. 相似文献

Reciprocal Relations Between Student–Teacher Relationship and Children's Behavioral Problems: Moderation by Child‐Care Group Size 
下载免费PDF全文
下载免费PDF全文 In this Norwegian study, bidirectional relations between children's behavior problems and child–teacher conflict and closeness were examined, and the possibility of moderation of these associations by child‐care group size was tested. Eight hundred and nineteen 4‐year‐old children were followed up in first grade. Results revealed reciprocal effects linking child–teacher conflict and behavior problems. Effects of child–teacher closeness on later behavior problems were moderated by group size: For children in small groups only (i.e., ≤ 15 children), greater closeness predicted reduced behavior problems in first grade. In consequence, stability of behavior problems was greater in larger than in smaller groups. Results are discussed in light of regulatory mechanisms and social learning theory, with possible implications for organization of child care. 相似文献

This paper analyses whether tertiary education of different types, i.e., academic or vocational tertiary education, leads to more or less favourable labour market outcomes. We study the problem for Switzerland, where more than two thirds of the workforce gain vocational secondary degrees and a substantial number go on to a vocational tertiary degree but only a small share gain an academic tertiary degree. As outcome variables, we examine the risk of being unemployed, monthly earnings, and variation in earnings (reflecting financial risk). We study these outcomes at career entry and later stages. Our empirical results reveal that the type of tertiary education has various effects on these outcomes. At career entry, we observe equal unemployment risk but higher average wages and lower financial risk for vocational graduates. At later career stages, we find that these higher average wages disappear and risk of unemployment becomes lower for vocational graduates. Thus, by differentiating the tertiary system into vocational and academic institutions graduates face a variety of valuable options allowing them to self-select into an educational type that best matches their individual preferences. 相似文献
