电视文本的比较研究

比较电视研究方法主要对不同国别不同语种的电视节目进行比较,从而发现和总结各民族与国家电视的价值和特色.比较电视分为影响比较和平行比较两种研究方法.影响比较侧重于影响者和被影响者的研究,平行研究侧重电视文本类同和对比的研究.把握好比较电视研究方法对于丰富和完善人们对于世界与人类电视的发展具有重要意义.     

2005年农民增收面临的困难

20 0 4年 ,各级党委和政府认真贯彻落实“一号文件”精神 ,极大地调动起了农民农业生产积极性 ,加上市场粮价回升、农业生产气候条件适宜等多方面有利因素 ,农民增收呈现近年来少有的好形势。据统计 ,全年农民人均纯收入 2 936元 ,增加 314元 ,实际增长 6 8% ,是 1997年以来收入增加最多和增长最快的一年。但是 ,制约农民增收的深层次矛盾还没有得到有效化解 ,2 0 0 5年实现农民收入较快增长的任务还很艰巨。　　一、2 0 0 4年农民增收的特点(一 )农业收入创历史新高农业收入在农民收入中具有举足轻重的地位 ,是农民收入的最大来源。近年来…     

创新办学模式 激活办学潜力——关于福建省侨兴轻工学校教育改革的探索和实践

中职教育,由于受计划经济体制的制约和传统教育思想的束缚,长期以来,存在着重书本知识轻实践技能的弊端,是一种以教师为中心的典型模式。我校围绕“以服务为宗旨,以就业为导向,面向市场和社会办学”的指导思想,顺应形势的发展进行了积极的探索和实践,加快了中职教育教学的改革步伐,促进了学校发展。     

Factor analysis for ranked data with application to a job selection attitude survey

Summary.  Factor analysis is a powerful tool to identify the common characteristics among a set of variables that are measured on a continuous scale. In the context of factor analysis for non-continuous-type data, most applications are restricted to item response data only. We extend the factor model to accommodate ranked data. The Monte Carlo expectation–maximization algorithm is used for parameter estimation at which the E-step is implemented via the Gibbs sampler. An analysis based on both complete and incomplete ranked data (e.g. rank the top q out of k items) is considered. Estimation of the factor scores is also discussed. The method proposed is applied to analyse a set of incomplete ranked data that were obtained from a survey that was carried out in GuangZhou, a major city in mainland China, to investigate the factors affecting people's attitude towards choosing jobs.

Gender,lineage, and fertility‐related outcomes in Ghana

A growing literature examines the empirical relationship between the joint reproductive preferences of marital partners and reproductive outcomes in Africa. Less explored is how spousal power in decision making may be influenced by lineage type. Using pooled data from Ghana, we investigate how lineage affects gendered reproductive decision outcomes and find some evidence that matrilineal women are more able than nonmatrilineal women to translate their reproductive preferences into action consistent with their goals.

HEAVY-TAILED-DISTRIBUTED THRESHOLD STOCHASTIC VOLATILITY MODELS IN FINANCIAL TIME SERIES

To capture mean and variance asymmetries and time‐varying volatility in financial time series, we generalize the threshold stochastic volatility (THSV) model and incorporate a heavy‐tailed error distribution. Unlike existing stochastic volatility models, this model simultaneously accounts for uncertainty in the unobserved threshold value and in the time‐delay parameter. Self‐exciting and exogenous threshold variables are considered to investigate the impact of a number of market news variables on volatility changes. Adopting a Bayesian approach, we use Markov chain Monte Carlo methods to estimate all unknown parameters and latent variables. A simulation experiment demonstrates good estimation performance for reasonable sample sizes. In a study of two international financial market indices, we consider two variants of the generalized THSV model, with US market news as the threshold variable. Finally, we compare models using Bayesian forecasting in a value‐at‐risk (VaR) study. The results show that our proposed model can generate more accurate VaR forecasts than can standard models.
