In this paper, we consider the problem of making statistical inference for a truncated normal distribution under progressive type I interval censoring. We obtain maximum likelihood estimators of unknown parameters using the expectation-maximization algorithm and in sequel, we also compute corresponding midpoint estimates of parameters. Estimation based on the probability plot method is also considered. Asymptotic confidence intervals of unknown parameters are constructed based on the observed Fisher information matrix. We obtain Bayes estimators of parameters with respect to informative and non-informative prior distributions under squared error and linex loss functions. We compute these estimates using the importance sampling procedure. The highest posterior density intervals of unknown parameters are constructed as well. We present a Monte Carlo simulation study to compare the performance of proposed point and interval estimators. Analysis of a real data set is also performed for illustration purposes. Finally, inspection times and optimal censoring plans based on the expected Fisher information matrix are discussed. 相似文献

Online role-playing games such as World Of Warcraft represent new participatory cultures in which today's students engage every day. They are appealing to players largely because of the social aspects of game play. Some features of massively multiplayer online role-playing games (MMORPGs) can be incorporated into classroom culture to create more dynamic interactions between students and improve both content instruction and civic competence. 相似文献

Although women influence nearly 85 percent of new car sales, their experience at automotive dealerships differs significantly from that of men. Not only are women subject to sexist and patronizing behavior from automotive personnel, but they also often wind up paying considerably more for a vehicle than a male customer. In the past two decades, the Internet has evolved as a significant source of automotive information and advice. While the majority of car advice websites offer guidance to the general public, a handful address the automotive concerns of the female driver. These sites are significant not only for the information they make accessible to female visitors, but for what women gain—as drivers, consumers, and political actors—by reading them. This paper examines four popular websites that cater specifically to the woman driver. Calling upon feminist epistemologies, it demonstrates how such online locations empower women to become more informed drivers and consumers through the accumulation and distribution of women's automotive knowledge. Not only does this automotive knowledge aid women as negotiators, but it also provides them with the tools necessary to radically transform the hostile auto dealership culture, ultimately benefiting all in the market for an automobile. 相似文献

This paper draws together empirical work that has been produced by the authors in two different autistic spaces: the Swedish magazine Empowerment produced by and aimed at adults with autism, and English-speaking autistic communities online. While the two points of data collection are quite different, there are important points of commonality that enable us to explore central issues concerning autistic and neurotypical space and the meanings assigned to these in different contexts. The paper aims to introduce the notion of social geographies of autism, based on talks among adults with autism and a social movement to promote autistic identities, giving examples from our previous work that has spanned both online and off-line spaces. Key issues discussed in the paper include a focus on autistic political platforms and the carving out of both social and political spaces for people with autism. In doing so, neuro-separate and neuro-shared spaces must be negotiated. 相似文献

Lot resubmissions are allowed in situations where the original inspection results are suspected or when the supplier is allowed to opt for resampling as per the provisions of the contract etc. This paper examines the situation of resampling of lots and derives the performance measures of a resampling scheme having a single sampling plan for inspection. The usefulness and limitations of resampling of resubmitted lots are also discussed 相似文献

行政检查的概念在学理研究和实定法上以多种面相出现,厘清这一概念尤为必要.文章梳理了日本、韩国、英美、我国台湾地区有关行政检查的概念,重点探讨了我国学理研究和实定法上有关行政检查的概念,并总结了行政检查含义的演变趋势.排除行政调查中纯粹的资料搜集行为,行政检查等同于行政调查,是指行政主体对行政相对人是否遵守国家的法律、法规、规章的情况,作单方面强制了解的行政行为 相似文献

针对中小学综合督导评估存在的问题,构建以促进学校特色发展和可持续发展为宗旨的“C-S”协同发展综合督导评估新模式.该模式通过督导评估理念、内容和流程的重构,超越了强调“全面评估、静态评估,注重‘评’、缺乏‘督’和‘导’”的传统督导评估模式,实现对学校的特色性、发展性督导评估,以专家为核心的民主性、专业性督导评估,以及以整改落实为关键的督导评估,从而整体上提升中小学综合督导评估的实效. 相似文献

SUMMARY Limited research exists that examines student perceptions of online discussions in fully online classes. This is a report of initial investigation into undergraduate distance education majors' perspectives of the pedagogical value of online discussions. Over a two semester period (Spring and Fall, 2003), students taking the same online course delivered using Web Course Tools (WebCT) were surveyed regarding opinions of online discussions. The students surveyed were undergraduate students enrolled in a fully online degree program at New Mexico State University (NMSU). Although limitations exist due to small sample size and a non-standardized data collection instrument, findings from this exploratory study offer insight into undergraduate distance education student opinions of the strengths and weaknesses of online discussions as a pedagogical tool. 相似文献
