On the Bivariate Kummer-Beta Type IV Distribution

Recent studies have shown the X-bar control chart with variable sampling interval detects shifts in the process mean faster than the traditional X-bar chart. These studies are usually based on the assumption that the process data are independently and normally distributed. However, many situations in practice violate these assumptions. In this study, a methodology is developed to economically design a variable sampling interval X-bar control chart that takes into consideration correlated non normal sample data. An example is provided to illustrate the solution procedure. A sensitivity analysis on the input parameters (i.e., the cost and the process parameters) is performed taking into account the non normality and the correlation on the optimal design of the chart.     

Evaluation of alternative confidence intervals to address non-inferiority through the stratified difference between proportions

The confidence interval (CI) for the difference between two proportions has been an important and active research topic, especially in the context of non-inferiority hypothesis testing. Issues concerning the Type 1 error rate, power, coverage rate and aberrations have been extensively studied for non-stratified cases. However, stratified confidence intervals are frequently used in non-inferiority trials and similar settings. In this paper, several methods for stratified confidence intervals for the difference between two proportions, including existing methods and novel extensions from unstratified CIs, are evaluated across different scenarios. When sparsity across the strata is not a concern, adding imputed observations to the stratification analysis can strengthen Type-1 error control without substantial loss of power. When sparseness of data is a concern, most of the evaluated methods fail to control Type-1 error; the modified stratified t-test CI is an exception. We recommend the modified stratified t-test CI as the most useful and flexible method across the respective scenarios; the modified stratified Wald CI may be useful in settings where sparsity is unlikely. These findings substantially contribute to the application of stratified CIs for non-inferiority testing of differences between two proportions.     

An experimental investigation into perceptions of disrespect during interpersonal conflict

Perceptions of disrespect are central to everyday life. Despite the importance of disrespect across various social arenas, prior research has failed to empirically examine the factors influencing these perceptions. This problem is magnified when considering that perceptions or disrespect may vary across individuals and social situations alike. Drawing from theories of social geometry and symbolic interaction, this study examines the individual and situational characteristics that inform perceptions of disrespect. Using factorial vignettes, and a large sample of students, respondents were asked to assess actors in various conflicts. Results from a series of hierarchical linear models show that perceptions of disrespect vary across individuals. The content of situations appears to drive perceptions of disrespect more than individual characteristics. Implications for future research on disrespect are discussed.     

The Almon two parameter estimator for the distributed lag models

The two parameter estimator proposed by Özkale and Kaç?ranlar [The restricted and unrestricted two parameter estimators. Comm Statist Theory Methods. 2007;36(15):2707–2725] is a general estimator which includes the ordinary least squares, the ridge and the Liu estimators as special cases. In the present paper we introduce Almon two parameter estimator based on the two parameter estimation procedure to deal with the problem of multicollinearity for the distiributed lag models. This estimator outperforms the Almon estimator according to the matrix mean square error criterion. Moreover, a numerical example and a Monte Carlo simulation experiment are presented by using different estimators of the biasing parameters.     

两周金文并列连词初探

两周金文中能肯定用为并列连词者有“暨、及、雩、以、与、[虘又]（且）、而、兼、又、唯”十词。从用法看,这些词可分为三类。一类是“又”,主要连接整数和零数,多用于计时的场合;一类是“[虘又]（且）”,主要连接形容词,基本只见于四字韵文中;其余各词主要连接名词或名词性成分,表现出用法上的一致性。从出现频率看,除了“又”用例很多,“暨”略多见外,其他各词都很少见,表明两周金文中的并列连词尚处于形成发展的过程中。出现时间上,“暨、雩、以、又、唯”只见于或主要见于西周时期,“及”主要见于春秋时期,“且、而、与、兼”只见于东周时期,表现出较为明显的时间性差异。     

皮日休与郑愚关系献疑

唐末竟陵籍作家皮日休与广州籍显宦郑愚之间属于座主门弟子关系,但他们个性、人生观等多方面存在着一些差异,在一些细节问题上发生过一定的误会和摩擦,本应亲密而转为隔膜.从皮、郑关系的考察中,可以看出皮日休的辩才、急智、桀骜不驯的性格,唐末文人风尚也可藉此而见一斑.

我国信访问题预警机制的全面整合

信访问题预警机制由信访预警系统的组织机构、职责分工、运行流程、监督执行以及保障系统构成。根据预警机制的功能链条,信访问题预警管理活动可分为信息汇集、信息分析、警情研判、警级发布、警势预控、应急管理等环节。只有当上述要素环节全面整合,一一贯穿到信访以及和信访相关系统的各个职能部门中,并协同运转,信访问题预警机制才能真正建成。
