Complete moment convergence and Lr convergence for asymptotically almost negatively associated random variables

In this paper, we investigate the complete moment convergence and L_r convergence for maximal partial sums of asymptotically almost negatively associated random variables under some general conditions. The results obtained in the paper generalize some corresponding ones for negatively associated random variables.     

Diffusion Indexes With Sparse Loadings

The use of large-dimensional factor models in forecasting has received much attention in the literature with the consensus being that improvements on forecasts can be achieved when comparing with standard models. However, recent contributions in the literature have demonstrated that care needs to be taken when choosing which variables to include in the model. A number of different approaches to determining these variables have been put forward. These are, however, often based on ad hoc procedures or abandon the underlying theoretical factor model. In this article, we will take a different approach to the problem by using the least absolute shrinkage and selection operator (LASSO) as a variable selection method to choose between the possible variables and thus obtain sparse loadings from which factors or diffusion indexes can be formed. This allows us to build a more parsimonious factor model that is better suited for forecasting compared to the traditional principal components (PC) approach. We provide an asymptotic analysis of the estimator and illustrate its merits empirically in a forecasting experiment based on U.S. macroeconomic data. Overall we find that compared to PC we obtain improvements in forecasting accuracy and thus find it to be an important alternative to PC.

On the mean L1-error in the heteroscedastic deconvolution problem with compactly supported noises

We study the heteroscedastic deconvolution problem when random noises have compactly supported densities. In this context, the Fourier transforms of the densities can vanish on the real line. We propose a truncated type of estimator for target density and derive the convergence rate of the mean L¹-error uniformly over a class of target densities. A lower bound for the mean L¹-error is also established. Some simulations will be given to illustrate the performance of the proposed estimator.     

Occupational rehabilitation services provided by a community workers health centre in Hong Kong: a case study

Ergonomics is commonly known as "the scientific study of human work" [14, p. 3] and "the application of scientific information concerning human beings to the design of objects, systems, and environments" (p. 4). The American Occupational Therapy Association defines occupational therapy as "skilled treatment that helps individuals achieve independence in all facets of their lives. It gives people the 'skills for the job of living' necessary for independent and satisfying lives [1]." Both professions share common backgrounds. Occupational therapy has been involved in health care and ergonomics is looking for its place in the health care field.     

Mobilization by images: TV screen and mediated instant grievances in the Umbrella Movement

This article discusses the effects of the televised images of the use of tear gas on people participating in the Umbrella Movement. Although the role of the Internet and social media in political mobilization has been widely discussed, the importance of television cannot be overlooked. This article argues that the widely transmitted broadcasts of live images of the police firing tear gas into the protesting crowd generated “mediated instant grievances” in a substantial sector of the viewing public, thus contributing to the size and scale of the Umbrella Movement. The study reported here provides evidence for this argument by analyzing the results of a survey of protesters that were on site during the early stage of the movement (N = 969). The study sought to determine whether and how the television images were related to the participants’ political attitudes, reasons for participation, and views of self-mobilized actions. The findings showed that, in particular, mediated instant grievances motivated the participation of the “amateur protesters” in the movement.     

三旧改造区域的城市更新效益分析——以广州北岸文化码头区域为例

城市更新目前已成为融合社会、经济、文化和物质环境全面复兴的城市公共政策,对城市的发展,尤其是对旧村庄、旧厂房、旧城镇等“三旧”区域的发展,有着重要的影响。本文拟以广州北岸文化码头为例,通过实地调研,从经济、社会和环境三个方面分析城市更新下三旧改造区域的用地效益。研究发现,经历城市更新后,北岸文化码头区域的经济效益主要体现在土地单位产出的提高,而用地的集聚效益尚不显著;但社会效益和环境效益则十分显著。     

网络论争中的青年社会情绪及价值取向解读——以“上海地铁二运事件”为例

2012年,上海地铁第二运营有限公司发布的一条官方微博引发了广泛的网络论战。围绕骚与扰的问题,在政务微博的权威性与通俗性如何权衡、网络时代的社会公共服务管理应如何作为、权利的边界与自由的限度该如何界定、个性张扬与自由标榜中是否也存在着对他人人格与尊严的无视与冒犯、公序良俗与法律对社会秩序的维护起着怎样的作用等问题上所形成的话语盛宴,为我们提供了一个解读当下青年的社会情绪及价值取向的生动范本。
