A new stratified three-stage unrelated randomized response model for estimating a rare sensitive attribute based on the Poisson distribution

This article suggests an efficient method of estimating a rare sensitive attribute which is assumed following Poisson distribution by using three-stage unrelated randomized response model instead of the Land et al. model (2011 Land, M., S. Singh, and S. A. Sedory. 2011. Estimation of a rare sensitive attribute using poisson distribution. Statistics 46 (3):351–60. doi:10.1080/02331888.2010.524300.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) when the population consists of some different sized clusters and clusters selected by probability proportional to size(:pps) sampling. A rare sensitive parameter is estimated by using pps sampling and equal probability two-stage sampling when the parameter of a rare unrelated attribute is assumed to be known and unknown.

We extend this method to the case of stratified population by applying stratified pps sampling and stratified equal probability two-stage sampling. An empirical study is carried out to show the efficiency of the two proposed methods when the parameter of a rare unrelated attribute is assumed to be known and unknown.     

论问题素养的创新驱动功能及教学培养机制

在问题与创新的逻辑关系中，是创新主体的问题素养内在而有效地驱动着创新。问题素养具有生命本然性、生活养成性、结构综合性、品质卓越性和人格指向性等丰富内涵，是由问题意识、问题境界、问题加工、问题体验、问题监控、问题解决心向等成分组成的系统结构，具有激发创新意识、引导创新精神、转化创新能力、承载创新行为和判定创新价值的驱动功能。问题素养培养的主渠道是课堂教学，应采取教学评价机制、信念突破机制、活动生成机制、模仿学习机制、专门训练机制和底蕴孕育机制，来培养和提升学生的问题素养。     

From salons to the native reserve: reformulating the “native question” through pictorial photography in 1950s South Africa

The article provides a critical reflection on the practice of photographic salon exhibitions in the 1950s. In South Africa and abroad, there was a resurgence of photographic societies from the early 1950s that encouraged amateur photographers to create images based on a distinct visual grammar, thereby offering them not only an opportunity to display their work but to compete amongst each other. Subsequently, salon exhibitions produced work that would be judged on its pictorial rather than strict representational value thereby depoliticising the exhibition space. On the other hand, this article seeks to place this practice in the realm of racial segregation under apartheid by considering the deployment of the “black subject” in the native rural reserve in Joseph Denfield’s (1911–1967) work. Through a study of his ethnographic photographs which were exhibited internationally in this period as pictorial work, as well as his intellectualisation of his practice as native photography, it argues that the space of the salon allowed him to pose the “native question” pictorially, that is, provided a discourse through which the “native” could be “known” and ordered.     

“科学技术是双刃剑”质疑

在学术界,持"科学技术是双刃剑"论的学者,似乎没有真正搞清楚科学技术的基本性质,因而他们的观点存在诸多明显缺陷。科学技术具有真、善、美的本性。具有真、善、美本性的科学技术,不可能同时包含着假、恶、丑的内容,因而"科学技术是双刃剑"的命题不合逻辑。人类在利用科学技术从事实践活动的过程中,常常会受到来自自然界盲目力量的报复,那是因为人类的无知。而一些个人、团体和国家利用科学技术从事犯罪活动,则根源于他们的贪婪,没有理由把他们犯下的罪行归咎于科学技术。     

程序正义理念下的死刑复核问题探析

受我国传统刑事诉讼价值取向的影响,现行死刑复核程序在实践运行中一直存在着很多问题,大大影响到死刑复核程序功能的实现。死刑核准权统一收归最高人民法院行使,既让我们在死刑复核问题上看到了希望,又给我们提出了新的研究课题。虽然近期最高人民法院及相关部门颁布了一系列指导死刑复核程序运作的相关规定,但从实际操作效果来看,仍有一些问题需要进一步明确。
