或有事项作为特殊的不确定性事项,是不确定性会计的重要内容。或有事项的确认和披露是当前会计理论和实务中的一大难点。要正确理解和运用财政部发布的《企业会计准则——或有事项》,必须明确或有事项与未来事项、估计事项及资产负债表日后事项的区别;正确理解负债、预计负债和或有负债之间的关系;正确区分或有事项的各种可能性及其会计处理;正确核算因或有事项确认的负债及相关的资产。 相似文献

This paper explores the influence of marital disruption and family environment on three major events that mark the transition from adolescence to young adulthood for children between the ages of 16 and 25, these being leaving school, entering the labor market and obtaining permanent employment. This is a gender approach, given that the two sexes experience the process in different ways.The duration models that estimate the timing of events reveal that the factors which favor education (i.e., intact family, parents’ education, mother more educated than father, mother never worked for pay) produce a higher-performance work path, and vice-versa (i.e., family disruption, number of siblings, caring for grandparents). The comparative gender analysis shows that daughters receive more education, are less likely to obtain a permanent job and, at the same time, they are more sensitive to the family environment and produce a positive externality on both brothers and sisters. 相似文献

回到教育事件本身——复杂性理论视域中的教育规律研究 总被引:1,自引:0,他引:1
复杂性理论把不确定性纳入研究视域,揭示了矛盾意义、概率意义特别是混沌意义上的规律观,揭示了有序与无序之间对立、竞争以及互补的复杂关系,打破了传统哲学教科书规律观被“必然性王国”统治的局面。从有序与无序的结合揭示教育活动的规律,即回到教育事件本身,揭示教育活动中有序、无序、组织和相互作用的四元联立关系,将使教育规律的研究更贴近现实、更彻底、更有说服力。 相似文献

Teacher intervention is an important factor in stopping bullying. Several studies indicate that teachers who believe they are capable of stopping bullying intervene more often in bullying. But this finding has only been based on hypothetical situations. It remains unclear if these results can be replicated in bullying interventions that the teachers actually performed. In addition, some studies claim that self‐efficacy is only connected to teacher intervention in direct forms of bullying, rather than indirect forms. In the current study, teachers' self‐efficacy in bullying interventions and the probability that they will intervene is investigated using self‐reported real‐life bullying situations in a sample of German teachers. Results show that teachers who feel more confident in dealing with bullying report intervening more often in bullying episodes they observed. Teacher training should include discussions of real‐life experiences to promote teachers' self‐efficacy beliefs and increase the probability of teacher intervention. 相似文献

In California incarcerated juveniles are legally mandated to attend school while behind bars. Previous research shows that the quality of education people receive behind bars can increase their educational attainment, improve the probability of other positive life chances, and lowers the likelihood of recidivism. As we interviewed incarcerated girls, they described their corrections-based educational experience as overwhelmingly positive. This paper examines why girls viewed these experiences so positively. Small classrooms, student-teacher relationships and interactions, and meeting the girls’s housing and food needs, each contributed to their positive outlook. Ultimately, being behind bars allowed them to access a more intimate, favorable educational experience. 相似文献

Rolling dice and tossing coins can still be used to teach probability even if students know (or think they know) what happens in these experiments. This article considers many simple variations of these experiments which are interesting, potentially enjoyable and challenging. Using these variations can cause students (and teachers) to think again about the statistical issues involved – and learn in the process. 相似文献

This paper presents an ethnographic study of the out of school literacy practices of children living in residential care in Malaysia. Although residential homes generate much publicity, especially during the festive seasons, not much is known about the children living within the confines of these homes. Even more lacking is research on their literacy practices, despite the embeddedness of literacy in the everyday lives of these children, which includes formal schooling, after‐school tuition classes and devotion sessions with volunteers. 相似文献

Prior to large experimentations on the teaching of probability theory, it appeared useful to observe some students working for a fairly long time. This observation should make more precise the difficulties of an important aspect when solving probability problems: the modelling aspect. Does systematic use of simulation produce miracles as it is sometimes said? Are the students naturally sensitive to a frequentist approach of probability theory? This paper contains some results on these questions, for example we pointed out for some students an obstacle to the frequentist approach. The results permit to conceive how using simulation for teaching could contribute to an improvement of students' approach to probability. 相似文献

中国共产党从诞生之日起,就历经了许多危机事件的考验。正是在应对各种危机事件挑战的过程中,中国共产党获得了相应的进步。危机事件对中国共产党发展的影响主要体现在三个方面:危机事件的非常状态锤炼了中国共产党人的特殊品格;危机事件的发展变化推动了中国共产党社会价值观的不断变迁;危机事件提供的特殊舞台促进了中国共产党领导水平和执政能力的提高。 相似文献

从一则谚语例谈小概率事件 总被引:2,自引:0,他引:2
在中国五千年的文化长河中,流传着许多谚语、典故,它们体现出了很强的哲学思想,人们往往对这谚语、典故的正确性深信不疑.其实,这些谚语、典故从数学角度来讲,说的是一些小概率事件.只要我们掌握了小概率事件的理论解说,就可以诠释它的哲学思想,认识小概率事件的现实表现,科学地选择好的小概率事件,避开不好的小概率事件,以便趋利避害. 相似文献

汉代史著如《史记》、《汉书》常引用传中人物自己所作的诗歌来增加表达效果,这些自作诗产生于特定的历史场合,很好地体现了人物在特定场合中的心境情绪,具有史家笔法不能达到的表达效果。人物自作诗多由"事象"感发,大部分是悲剧人物在困境中发出的悲鸣。史著中引用的诗歌往往能与历史叙事相互交融,起到诗史互证的作用。 相似文献
