A new discrete distribution defined over all the positive integers and with the name of Geeta distribution is described. It is L-shaped like the logarithmic series distribution, Yule distribution and the discrete Pareto distribution but is far more versatile than them as it has two parameters. It belongs to the classes of location parameter distributions, modified power series distributions, Lagrange series distributions and exponential distributions. Its mean fi, variance a2 and two recurrence formulae for higher central moments are obtained. Convolution theorem and variations in the model with changes in the parameters have been considered. ML estimators, MVU estimators and estimators based of mean and variance and on mean and first frequency have been derived.  相似文献

We study a hypothesis testing problem involving the location model suggested by Olkin and Tate (1961). Specifically, we derive a likelihood ratio lest of the associated location hypothesis as an alternative to the conventional method of carrying out separate tests for each of the parameters. A small sample Monte Carlo comparison indicates the general superiority of the former in terms of statistical power. We also comment briefly on the properties of the test.  相似文献

Individuals with autism spectrum disorders (ASDs) have complex needs requiring regular service utilization. Policymakers, administrators, and community leaders are looking for ways to finance ASD services and systems. Understanding the fiscal resources that support ASD services is essential. This article uses fiscal mapping to explore ASD funding streams in Ohio. Fiscal mapping steps are overviewed to assist ASD stakeholders in identifying and examining ASD-related funding. Implications are drawn related to how fiscal mapping could be used to identify and leverage funding for ASD services. The resulting information is critical to utilizing existing resources, advocating for resources, and leveraging available funds.  相似文献

鉴于先前较为混乱的书号管理秩序及其给出版业带来的消级影响,书号实名中领制应运而生,它对于国家整合出版资源、加强宏观调控、规范市场秩序,出版社加快出版节奏、提高市场竞争都有一定的成效,但书号实名申领制在具体的运物过程中,也还存在一些弊端,因此,它还有待于进一步改进。  相似文献

阶层流动以精英流动为主要实现方式,精英流动受阻意味着阶层固化,阶层固化是集团分利的后果之一,是“机构僵化症”的同义语.中国在市场转型过程中形成了各类精英集团,精英集团的分利行为造成资源的集团式垄断,而阶层流动又以资源占有为前提,精英便趋于集团内或集团间复制,阶层固化趋势加剧.实现公平分利以建立良性精英流动机制、适度硬政权建设以打破分利集团联盟及制度变革与创新以重构利益格局是消除阶层固化的路径选择.  相似文献

Abstract

Objectives: This study investigated the experiences of gay, bisexual, and other men who have sex with men (GBM) conducting HIV and sexually transmitted infection (STI) self-testing procedures. Methods: We analyzed mixed-methods data from 11 GBM who self-tested HIV-positive and 1,070 HIV-negative GBM who completed the HIV self-testing and STI self-sampling procedures. Results: Nearly all (99%) reported ease in urine-based STI self-sampling and most (90%) found rectal swab self-collection easy. Most (94%) checked their rapid-HIV self-testing results during the correct window (20-40 minutes), and nearly all (99%) trusted their HIV results. Conclusions: Recommendations for future self-testing procedures are provided based on findings from free-response data.  相似文献

接受美学理论十分重视本文一读者关系,特别强调读者在本文意义解读与重构过程中的主体地位。网络环境下的大学英语教学的研究视点也从教师主体转向了学生主体,把学生视为几个教学常量中的主导因子,关注学生主体身份的构建。在此意义上,接受美学理论对新环境下的大学英语教学有很强的解释力。  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

Abstract

This article addresses the affective, emotional, and familial dimensions of urban everyday mobility. Drawing on theoretical inspiration from phenomenology, non-representational theory, and mobilities research on the relational mobilities of children and families, the paper explores the everyday mobility of 11 households with children in the multi-modal context of Copenhagen, Denmark. Following the conceptualization of everyday mobility practices as heterogeneous ‘negotiation in motion’, the empirical analysis investigates how the strong relational dynamics between household members are organized around affect, care, familial bonding, and the rhythms of everyday life, which shape spatial patterns of moving together and apart. A new qualitative method combining GPS tracking, mapping, and household interviews is explored to show how everyday patterns of relational mobility are filtered through spatial affordances, affective ambience, and the temporalities of the lifecourse to influence transport alternatives of route and modal choices.  相似文献
