Thomas Dew and the rise of proslavery ideology at William & Mary

In 1831, Nat Turner led an insurrection in Southampton County, Virginia that left more than 60 men, women, and children dead. This slave revolt left white Virginians in fear for their lives and questioning the ‘peculiar institution’ in their midst. Proslavery ideologue and William & Mary professor, Thomas Roderick Dew, stepped in and provided the intellectual foundation that calmed their fears and made the continuation of the southern way of life possible – at least for a little while longer.     

The use of vignettes to empower effective responses to attempted sexual assault

Objective: Women assertively resisting sexual aggression have the best chances of avoiding completed rape. Especially with acquaintances, there are significant social and psychological barriers to resistance. Novel vignettes depicting acquaintance rape were designed to enhance self-efficacy, reduce unrealistic optimism, and empower assertive resistance. Participants: The data were collected using a Web-based survey of 449 female college students from multiple universities in August–October 2014. Methods: Between-subjects mixed-methods design. Participants were randomly assigned to read one of four vignettes and complete self-report measures of personal vulnerability, self-efficacy, and beliefs and intention about resistance. Results: Although vignettes did not impact self-efficacy, one vignette enhanced perceived controllability and decreased unrealistic optimism. Women who read about completed acquaintance rape described intention to use physically assertive responses at double the rate of women reading about successful resistance. Conclusions: As low-cost, easily disseminated materials, vignettes about sexual assault may enhance campus prevention efforts.     

唐宋书法观念研究

唐代、宋代的书法观念是中国古代封建社会书法观念的典型代表,二者之间又有颇为明显的异同之处。正如常人所说的＂唐书法＂就是说唐代书法对于字体规范、风格法度有着严密的内在要求,其实由于科举进仕的需要以及宋人文化素养的普通提升,宋代文人对＂法＂也有着自觉地遵循。同时,在宋代还大量出现了＂游与艺＂、＂以书为乐＂等更为轻松的书法观念。     

The estimation of treatment effect for the censored bivariate data under the univariate censoring

This paper establishes a nonparametric estimator for the treatment effect on censored bivariate data under unvariate censoring. This proposed estimator is based on the one from Lin and Ying(1993)'s nonparametric bivariate survival function estimator, which is itself a generalized version of Park and Park(1995)' quantile estimator. A Bahadur type representation of quantile functions were obtained from the marginal survival distribution estimator of Lin and Ying' model. The asymptotic property of this estimator is shown below and the simulation studies are also given     

Contraceptive Responsibility among Male University Students

Abstract

This paper assesses the male contribution to contraceptive mismanagement and unwanted pregnancy. The subjects were 109 students at the University of Melbourne. A high incidence of risk-taking was reported, and almost one-fifth of the sexually experienced men stated that they had been involved in an unwanted pregnancy. A small group of these reported more than one such incident. The underlying reasons for poor contraceptive technique seemed to be related to two beliefs: that contraception is a female responsibility, and that sexual intercourse should be entirely spontaneous and unplanned.     

美国等五国"华人三重性"的比较研究

20世纪90年代以来,对华侨、华人的研究涉及历史、政治、经济、文化、社会等众多领域,涌现了一批有重要学术价值的专著。其中,韩方明博士在其论著《华人与马来西亚现代化进程》中,以马来西亚为例阐释了“华人三重性”即中华性、本地性、国际性的基本内涵。他提出的“华人三重性”理论使笔者深受启发。他指出:“华人三重性是对海外华人本质特征的一个理论表述……在不同的国家会有不同的内容及表现形式,对此进行研究,可以揭示不同国家华人问题的共性和个性。”①而目前学术界多侧重对同一地域不同国家的华人进行比较研究,尚未有人将“华人三重…

Symmetrical Design of Experiment in Global Sensitivity Analysis Based on ANOVA High-dimensional Model Representation

This article reviews symmetrical global sensitivity analysis based on the analysis of variance of high-dimensional model representation. To overcome the computational difficulties and explore the use of symmetrical design of experiment (SDOE), two methods are presented. If the form of the objective function f is known, we use SDOE to estimate the symmetrical global sensitivity indices instead of Monte Carlo or quasi-Monte Carlo simulation. Otherwise, we use the observed values of the experiment to do symmetrical global sensitivity analysis. These methods are easy to implement and can reduce the computational cost. An example is given by symmetrical design of experiment.     

New recursive estimators of the time-average variance constant

Estimation of the time-average variance constant (TAVC) of a stationary process plays a fundamental role in statistical inference for the mean of a stochastic process. Wu (2009) proposed an efficient algorithm to recursively compute the TAVC with \(O(1)\) memory and computational complexity. In this paper, we propose two new recursive TAVC estimators that can compute TAVC estimate with \(O(1)\) computational complexity. One of them is uniformly better than Wu’s estimator in terms of asymptotic mean squared error (MSE) at a cost of slightly higher memory complexity. The other preserves the \(O(1)\) memory complexity and is better then Wu’s estimator in most situations. Moreover, the first estimator is nearly optimal in the sense that its asymptotic MSE is \(2^{10/3}3^{-2} \fallingdotseq 1.12\) times that of the optimal off-line TAVC estimator.     

Are mating strategies and mating tactics independent constructs?

This study explored the constructs of mating tactics and mating strategy. These constructs are conceptually related but distinct. In current research, the measurement of one of these constructs is often viewed as being indicative of the other. Therefore, an exploration of these constructs will enhance understanding of study outcomes in this research area. Self-report measures of mating tactics and strategies were administered to 183 female participants, aged 18-45 years. The Escalating Sexual Encounters Questionnaire (ESEQ, Greer & Buss, 1994), the Derogatis' Sexual Experience Scale (Derogatis & Melisaratos, 1979), the Sexual Strategies Measure (SSM, Schmitt, 1996), the Sociosexual Orientation Inventory (Simpson & Gangestad, 1991), and two questions assessing age at menarche and total number of sexual partners were administered. Exploratory factor analysis with oblique rotation produced two distinct factors reflecting a "tactic"-based factor and a "strategy"-based factor. This finding is consistent with viewing mating tactics and mating strategies as distinct and varying independently. An important implication of this study is that measurement of mating tactics is not indicative of underlying mating strategies in women. Further, four patterns of female mating style emerged upon review of participant factor scores and are discussed within an evolutionary context.
