博弈下的暗涌——解读20世纪中期英国加勒比流散文学

20世纪中期英国殖民统治逐渐走向衰落,与此同时美国正在迅速崛起,曾称霸一时的英国文化面临着被其取代甚至同化的危机。因此英国文化不断寻找着既能助其保持殖民统治,又能抵制美国化的同盟军。它们在英国加勒比移民文化中找到了可团结的力量,以此一度对加勒比移民采取拉拢的态度。反映在文学上,加勒比流散文学也需要这种拉拢才能得到英国主流文化的承认,并确立其在英国的地位,因此欣然接受拉拢,甚至主动向其靠拢;但流散书写总是不断对自我身份进行重新审视,这使加勒比作家进一步反抗殖民主义和帝国主义对其的统治。由此,二者之间虽呈现出短暂的、反常的融洽,但这种平衡终究会被打破。20世纪中期英国加勒比流散文学正是这一特殊时期的典型反映。     

Revisiting retesting in the estimation of proportions by group testing

In the estimation of a proportion p by group testing (pooled testing), retesting of units within positive groups has received little attention due to the minimal gain in precision compared to testing additional units. If acquisition of additional units is impractical or too expensive, and testing is not destructive, we show that retesting can be a useful option. We propose the retesting of a random grouping of units from positive groups, and compare it with nested halving procedures suggested by others. We develop an estimator of p for our proposed method, and examine its variance properties. Using simulation we compare retesting methods across a range of group testing situations, and show that for most realistic scenarios, our method is more efficient.     

Social identity and alcohol in young adolescence: the perceived difference between youthful and adult drinking

This paper examines the evolving social identities of young adolescents in regard to alcohol and drinking culture in Norway. Detailed analysis of 29 focus group interviews and 32 individual interviews with 12–13-year-olds reveal a thorough negative attitude towards alcohol, especially when enjoyed by young people. Young adolescents found young people to be too irresponsible and immature to drink, while adults were portrayed as capable of enjoying alcohol without losing control or experiencing other negative effects. Through symbolic boundary work, they distanced themselves from adolescents who drank. The young adolescents rejected the idea that drinking alcohol was a sign of maturity; instead, they exhibited maturity by distancing themselves from drunk adolescents. We discuss how these findings reflect the participants’ socio-cognitive development, and how symbolic boundaries are often drawn against those closest in social distance. We conclude that boundaries between ‘adolescents’ and ‘adults’ are fundamental when understanding emerging adolescent social identities, especially when it comes to drinking and drinking culture.     

Wavelet Estimator in Nonparametric Regression Model with Dependent Error’s Structure

In this article, we consider a nonparametric regression model with replicated observations based on the dependent error’s structure, for exhibiting dependence among the units. The wavelet procedures are developed to estimate the regression function. The moment consistency, the strong consistency, strong convergence rate and asymptotic normality of wavelet estimator are established under suitable conditions. A simulation study is undertaken to assess the finite sample performance of the proposed method.     

Estimating the population proportion in modified ranked set sampling methods

In this paper, proportion estimators and associated variance estimators are proposed for a binary variable with a concomitant variable based on modified ranked set sampling methods, which are extreme ranked set sampling (ERSS), median ranked set sampling (MRSS), percentile ranked set sampling (Per-RSS) and L ranked set sampling (LRSS) methods. The Monte Carlo simulation study is performed to compare the performance of the estimators based on bias, mean squared error, and relative efficiency for different levels of correlation coefficient, set and cycle sizes under normal and log-normal distributions. Moreover, the study is supported with real data application.     

Non uniform exponential bounds on normal approximation by Stein’s method and monotone size bias couplings

It is known that the normal approximation is applicable for sums of non negative random variables, W, with the commonly employed couplings. In this work, we use the Stein’s method to obtain a general theorem of non uniform exponential bound on normal approximation base on monotone size bias couplings of W. Applications of the main result to give the bound on normal approximation for binomial random variable, the number of bulbs on at the terminal time in the lightbulb process, and the number of m runs are also provided.     

Portrayals of the internal God among Ashkenazi Jewish Orthodox lesbians in Israel

Abstract

Most of the existing literature on Ashkenazi Orthodox Jewish lesbians focuses on sociological aspects, mainly the negative attitudes held by religious communities towards their sexual identity and the various problems that arise from these. Less attention has been paid to lesbians’ psychological coping mechanisms with the tensions between their two central identities: the religious and the sexual. Ashkenazi Orthodox lesbians find themselves in a complicated situation where they remain on the margins of both their “natural” communities: the religious one and the homosexual one. As a result, they feel rejected, isolated, and even punished by society. As believers, God is their ultimate refuge. But there are different conceptions of God, ranging from benevolent to persecutory, accepting or highly judgmental and punishing. This variance has not been considered in regard to the dual identity of Ashkenazi Orthodox lesbians. This article focuses on this neglected issue, examining Ashkenazi Orthodox lesbians’ conception of God and its relation to their managing the conflict between their apparently conflicting identities.     

Estimation and simulation of conditional hazard function in the quasi-associated framework when the observations are linked via a functional single-index structure

We consider the estimation of the conditional hazard function of a scalar response variable Y given a Hilbertian random variable X when the observations are linked via a single-index structure in the quasi-associated framework. We establish the pointwise almost complete convergence and the uniform almost complete convergence (with the rate) of the estimate of this model. A simulation is given to illustrate the good behavior in the practice of our methodology.     

Perceptions of transition-related health and mental health services among transgender adults

The opportunity to live authentically is critical for the well-being of transgender individuals. For many this requires accessing transition-related services. Current knowledge of transition-related care is limited. This study aims to elucidate experiences and needs of transgender individuals (N = 65) related to (a) therapeutic support, (b) medical care, and (c) aspects of living authentically in order to inform the development and delivery of trans-affirmative services. Findings reveal challenges accessing health care providers with trans-specific competency; gaps between critical aspects of transition-related care and receipt of services; and heterogeneity of experiences and needs. Recommendations for improving transgender-affirmative services are provided.
