从马克思主义的国家学说看达赖集团分裂祖国的反动本质

西藏自古以来就是中国的一部分,这无论是过去还是现在都是全世界各国所公认的事实.以达赖为首的民族分裂集团,自1959年叛逃后,在国外长期从事民族分裂活动,利用国际上提供的各种场合,到处宣称"西藏自古以来是一个独立国家"的反动谬论,利用混淆古代国家与现代国家的概念,不仅搞乱了人民群众的思想,模糊了人民群众的视线,同时也造成了极大的危害,为其推行"民族独立"的分裂活动张目.我们必须以马克思主义国家学说为指导,牢固掌握西藏自古以来就是中国的一部分的科学内涵,牢固树立正确的马克思主义祖国观,以实际行动抵制达赖的民族分裂活动,积极维护祖国统一和民族团结,为建设团结、富裕、文明、和谐的社会主义新西藏而努力奋斗.

Time and exclusion

Drawing on interviews with parents of children with complex disabilities in several school systems in a US state, this paper examines how temporal units such as the school day and school year and practices organized around artifacts like clocks and calendars work as ‘devices of temporal distanciation’ to separate children with disabilities from other children and exclude their families from critical relations with schools. The paper focuses on two kinds of effects: the ways differentiated timetables separate children and the ways constructing school time in bounded, discrete units limits the ability of parents and children to make key elements of their lives visible to the school.     

Playing With Time: Gay Intergenerational Performance Work and the Productive Possibilities of Queer Temporalities

This article examines the tendencies of LGBT intergenerational theater projects. By engaging with ideas of queer time, temporal drag, and the pervasive heteronormative imagery of heritability and inheritance, this article explores the possibility that LGBT intergenerational projects may generate some of the problems they aim to challenge. Through the lens of queer time, the article describes the normativity generated in LGBT intergenerational theater projects as a form of restrictive interpellation. The article explores the temporal complexities at play in such theater productions as The Front Room, a specific LGBT intergenerational theater project performed in the United Kingdom in 2011. The article concludes by noting some ways in which intergenerational theater projects might seek to work through the embodiment of the historical quotidian as a mode of resistance to normativity’s recirculation.     

“Double-dose” English as a strategy for improving adolescent literacy: Total effect and mediated effect through classroom peer ability change

“Double-dose” coursework has become an increasingly popular strategy to assist low-performing students succeed in academic coursework. Chicago implemented a “double-dose” English policy in 2003. This policy not only provided additional instructional time to struggling readers, but also intensified skill-based sorting in English classes. I use policy-induced variation to infer the policy effect on students’ reading achievement and the effect mediated by classroom peer ability change. Results show very weak, but positive effects of taking double-dose English for students with average skills. However, potential benefits of doubled instructional time are likely to be offset by negative effects of declines in classroom peer ability. Students with very weak skills experienced minimal change in classroom peer ability, and two-period coursework is likely to benefit these students.

Homemaking,Temporality and Later Life

Abstract

While much literature has focused on the meaning of home, relatively little has been conducted on homemaking in later life. This paper demonstrates the importance of time in conceptualizations of home. Using an extensive case study from a multi-interview study with eight older people in England, it is shown that gardening can form the basis of a temporal framework which structures a life. Importantly, gardening can seem essential in homemaking and a reason not to move to residential living. This paper builds on literature that suggests home is a process and that people’s conceptualization and experience of home develop throughout their lives. As ageing and dying have become long and complicated processes, it is argued older people may find this challenging as this makes it difficult to prepare for the end of life.     

Retrospective change detection in categorical time series

The aim of this paper is to propose methods of detecting change in the coefficients of a multinomial logistic regression model for categorical time series offline. The alternatives to the null hypothesis of stationarity can be either the hypothesis that it is not true, or that there is a temporary change in the sequence. We use the efficient score vector of the partial likelihood function. This has several advantages. First, the alternative value of the parameter does not have to be estimated; hence, we have a procedure that has a simple structure with only one parameter estimation using all available observations. This is in contrast with the generalized likelihood ratio-based change point tests. The efficient score vector is used in various ways. As a vector, its components correspond to the different components of the multinomial logistic regression model’s parameter vector. Using its quadratic form a test can be defined, where the presence of a change in any or all parameters is tested for. If there are too many parameters one can test for any subset while treating the rest as nuisance parameters. Our motivating example is a DNA sequence of four categories, and our test result shows that in the published data the distribution of the four categories is not stationary.     

An Adaptive Functional Autoregressive Forecast Model to Predict Electricity Price Curves

We propose an adaptive functional autoregressive (AFAR) forecast model to predict electricity price curves. With time-varying operators, the AFAR model can be safely used in both stationary and nonstationary situations. A closed-form maximum likelihood (ML) estimator is derived under stationarity. The result is further extended for nonstationarity, where the time-dependent operators are adaptively estimated under local homogeneity. We provide theoretical results of the ML estimator and the adaptive estimator. Simulation study illustrates nice finite sample performance of the AFAR modeling. The AFAR model also exhibits a superior accuracy in the forecast exercise of the California electricity daily price curves compared to several alternatives.
