The effect of different data structures,sample sizes on model fit measures

In this study, our aim was to investigate the changes of different data structures and different sample sizes on the structural equation modeling and the influence of these factors on the model fit measures. Examining the created structural equation modeling under different data structures and sample sizes, the evaluation of model fit measures were performed with a simulation study. As a result of the simulation study, optimization and negative variance estimation problems have been encountered depending on the sample size and changing correlations. It was observed that these problems disappeared either by increasing the sample size or the correlations between the variables in factor. For upcoming studies, the choice of RMSEA and IFI model fit measures can be suggested in all sample sizes and the correlation values for data sets are ensured the multivariate normal distribution assumption.     

Optimal and lead-in adaptive allocation for binary outcomes: A comparison of Bayesian methods

We compare posterior and predictive estimators and probabilities in response-adaptive randomization designs for two- and three-group clinical trials with binary outcomes. Adaptation based upon posterior estimates are discussed, as are two predictive probability algorithms: one using the traditional definition, the other using a skeptical distribution. Optimal and natural lead-in designs are covered. Simulation studies show that efficacy comparisons lead to more adaptation than center comparisons, though at some power loss, skeptically predictive efficacy comparisons and natural lead-in approaches lead to less adaptation but offer reduced allocation variability. Though nuanced, these results help clarify the power-adaptation trade-off in adaptive randomization.     

Bayesian expectile regression with asymmetric normal distribution

In this paper, we adopt the Bayesian approach to expectile regression employing a likelihood function that is based on an asymmetric normal distribution. We demonstrate that improper uniform priors for the unknown model parameters yield a proper joint posterior. Three simulated data sets were generated to evaluate the proposed method which show that Bayesian expectile regression performs well and has different characteristics comparing with Bayesian quantile regression. We also apply this approach into two real data analysis.     

Who needs Cantonese,who speaks? Whispers across mountains,delta, and waterfronts

This essay digs into the ‘dirtiness’ of cultural studies to prioritize praxis, or as the way my mountain folks collect summer lotus: putting our feet in the muddy water, and finding ways to get the stems underneath the smooth leaves. Using Cantoneseness as a case to locate such ‘dirtiness’, I draw on personal/familial histories as well as research projects to tell how conjunctures of Cantoneseness are politically and unevenly lived. This complex journey travels roughly from my childhood in the Yuebei mountains of northern Guangdong through my teenage and early adult years in the Pearl River Delta (PRD) to my current location as a temporary resident in the East Pacific port of Vancouver. I selectively emphasize and speak on three different locations: first, the rural inland Cantonese location of Yuebei mountains – the borderland and hinterland experiences of my family and myself living what the mountains would offer and how these have changed; second, the industrial superior Cantonese location of PRD in Shenzhen and Guangzhou – my personal experiences and identities as a migrant youth, combined with a case study including interviews with migrant peasant-workers and their children; and third, the western transnational Cantonese location of East Pacific waterfronts in Vancouver and Richmond – my personal engagement with social activism as an ethnicized, international student, combined with a narrative study including interviews with social activists with different Cantoneseness and migration routes. While this mix of whispers speaks in its own way towards using cultural studies with more seriously (global) space-sensitive and (social justice) praxis-sensitive approaches, the primary focus is more modestly on my autobiographical accounts and research efforts as a specific case: to show some strategic locations of ‘Cantonescape’ on the one hand, and to invite wider conversations around cultural-spatial politics on the other.     

论植甄隐情为古诗背景的接受——木斋学说的情爱革命

木斋关于五言诗研究,以古诗十九首为曹植甄后爱情结果的立论最受到争议。个中原因除了传统文化对政治的依附造成在文学作品解读与评断上以国家政治为显而男女之情为隐的情形之外,历来文学史对古诗十九首纯诗化的美学接受亦是对此种学说的挑战。木斋学说不仅是在思考方式、研究方法上的革命,更是一种对于社会、政治、人性精神上价值观的思想革命。     

麦尔维尔创作中的通俗小说手法

随着后现代文艺思潮的盛行,严肃小说和通俗小说界限的消失,对麦尔维尔的研究也不再囿于传统的束缚.从麦尔维尔作品中采用的通俗小说手法入手,尤其是对其在具体作品中采用的讽刺冒险、哥特、城市暴露和言情等通俗小说模式逐一论述.麦尔维尔在创作中吸纳诸多的通俗手法,不只是为了取悦读者,更多的是为了实现自己的创作理念、形成自己独特的创作风格,从而在更深、更高的层次上实现与读者的心灵沟通.

从文化缺省角度看《围城》的翻译

来自同一社会文化背景的成员都具有关于这一社会文化的共同的知识,在交际过程中,这些共同知识作为背景知识常常被交际双方所省略。如果被省略的部分与语篇外的文化背景知识有关,那么这部分的缺省就是文化缺省。在翻译过程中,译者要补偿由这种具有鲜明文化特性的文化缺省所造成的意义真空。以珍妮·凯利（Jeanne Kelly）和茅国权翻译的《围城》为例,分析了译者所采取的几种翻译方法以及译者如何补偿《围城》中所体现的在中国社会文化中作为预设的文化和情境认同在英语文化中的缺失。
