The coming of a classical world

Quantum theory’s unusual predictions stem from its basic formalism which involves concepts like the wavefunction or probabilityamplitudes instead of probabilities. Many serious doubts have been raised about quantum theory’s connection with perceived classical dynamics. How does quantum mechanics, with all its strange ideas, unfold to give us the ‘reality’ of the familiar physical world? What is the connection between theclassical and thequantum! If quantum mechanics is, indeed, the fundamental theory of nature, as is widely accepted, then how does it explainclassicality! In the following, some of the fascinating conceptual problems of quantum mechanics are highlighted. The ‘environment-induceddecoherence’ approach is then discussed as one practical attempt at explaining the emergence of a classical world from an underlying quantum substrate

What do I think about inclusive education? It depends on who is asking. Experimental evidence for a social desirability bias in attitudes towards inclusion

Recently, research has focused on attitudes towards inclusive education, and the majority of studies use questionnaires to measure this vital variable. In two consecutive experiments, we showed that attitudes towards inclusive education are not stable but instead are significantly influenced by social context. We manipulated information on the organisation conducting a survey regarding attitudes of participants towards inclusive education. The results show that the attitude of the organisation conducting the survey – as perceived by the participant – outperforms well-documented variables (e.g. sex, age, and contact to a person with disability) in predicting the attitudes of the participant towards inclusion. This one variable explains as much variance as all other predictors combined. We argue that social desirability is a neglected issue in research on attitudes towards inclusive education. Our findings challenge the validity of numerous studies on this topic because they show a positive bias in the attitudes of participants when they were surveyed by a university. Thus, we outline the first steps to reduce social desirability-induced validity problems in research on attitudes towards inclusion.

骶骨棒内固定技术的解剖学研究

目的:虽然髂后嵴常被用于不稳定型骨盆骨折的固定,我们对髂后嵴进行解剖测量探讨骶骨棒内置的安全性。方法:共解剖32具尸体标本,男18具,女14具,从L5椎板上缘至两侧髂后上棘不同水平测量腰骶管至双侧髂后嵴顶点连线的距离。结果:发现所有标本从L5椎板上缘至两侧髂后上棘水平间其距离都大于要求的12mm安全距离,最大距离位于L5-S1接合处水平,在髂后上棘水平以下平均距离为8.88mm。结论:从L5椎板上缘至两侧髂后上棘间的髂后嵴区域安全且骨质量较好可用于骶骨棒的安全、有效固定,在髂后上棘水平以下安装骶骨棒是危险的。
