广西环北部湾少数民族新农渔村几种成功的发展模式

在中国新农村建设、泛北部湾区域经济合作的大背景下,广西环北部湾建设应更多地关注该区域内的少数民族的农渔村建设.本文在调查研究广西环北部湾地区不同地理位置、不同民族特色的几种少数民族新农渔村模式的基础上,总结出当前广西环北部湾地区新农渔村建设的成功经验和教训.     

城市群可持续发展水平演化及其影响因素研究——来自中国十大城市群的证据

采用基于变异系数的灰色关联分析方法,度量2002-2011年中国十大城市群可持续发展水平并分析其收敛性和影响因素。研究发现:十大城市群在经济发展水平、社会进步程度、生态环境状况、资源供给能力方面呈现显著的差异,城市群可持续发展水平并没有与经济增长的大趋势保持一致;城市群可持续发展水平收敛特征具有分区域特点,全国样本具有非绝对收敛但条件收敛的特征,东部地区城市群绝对收敛特征不显著,但条件收敛特征较明显,而中部与西部城市群具有绝对收敛和条件收敛特征;经济发展水平、社会进步程度等变量与城市群可持续发展水平之间正向相关,但其影响程度在不同区域具有显著差异。     

EFFECTS OF LEARNING ON RESOURCE ALLOCATION DECISIONS

Learning curves have important implications for managerial planning and control. This paper considers the effect of learning on managerial planning models for productmix problems that can be handled by a linear-programming formulation. An approach to incorporate learning effects in the planning model is proposed in this paper. The feasibility and superiority of the proposed approach over the traditional approach are discussed through the use of a linear-programming problem.     

中华民族共同体建设视阈下改土归流的历程、原因及作用

明清时期中央王朝实施的改土归流,不仅彻底废除了土司的政治、经济、军事、司法等特权,将国家版图内的人事权、财政权、军事指挥权、行政管理权、文化教育权等悉数收归中央,而且也是中华民族共同体由“自在”向“自觉”过渡的关键环节。明清改土归流经历了一个长期、艰巨、复杂的过程,其中既有土司利益与王朝利益的矛盾、各地土司与辖区民众的矛盾,也有中央王朝通过改土归流以增加税收、朝廷命官与乡村民众要求改土归流等现实动因。改土归流实现了国家“大一统”的目标、凸显明清国家治理能力的进步、加快了中华民族共同体建设的速度。中华民族共同体是一个由政治共同体、经济共同体、文化共同体和社会共同体四者构成的命运共同体。改土归流的实施,不仅是推动共同体由“自在”向“自觉”迈进的关键步骤和重要举措,而且使中华民族共同体在政治、经济、文化和社会诸方面发生巨大变化。     

媒体框架建构:研究中国-东盟博览会报道的新视角

媒体框架建构是指媒体以一定社会文化为背景,在客观事实的基础上框选部分事实并加以重组的过程。通过分析《广西日报》关于中国—东盟博览会报道的主题框架和结构框架可以看出：媒体框架的建构主要受到媒体所处意识形态环境以及媒体自身定位等综合因素的影响,同时,媒体框架的建构有利于媒体实现引导舆论,把握舆论话语权的目的。     

Is Tattooing a Risk Factor for Adolescents’ Criminal Behavior? Empirical Evidence from an Administrative Data Set of Juvenile Detainees in Taiwan

Juvenile crime affects not only the victims of the crime but also the delinquents’ future. How to prevent adolescent criminal behavior has become an important public policy issue. This study contributes to this interesting issue by examining the relationship between tattooing and adolescents’ criminal behavior. In particular, this study investigates whether or not having a tattoo/tattoos is connected to the incidence of various criminal activities, including: larceny, robbery, fraud, assault, drug use, and homicide. A unique sample of 973 juvenile detainees drawn from the administrative profiles in Taiwan and the coarsened exact matching method were utilized. Results show that compared to their nontattooed counterparts, tattooed juvenile detainees were significantly more likely to commit fraud, assault, drug abuse, and homicide by 3%, 13%, 9%, and 9%, respectively. In contrast, tattooing was not significantly associated with larceny or robbery. From a policy perspective, given the significant link between tattooing and criminal behavior, the presence of a tattoo in adolescents may serve as a valuable indicator regarding adolescents’ high probability of committing crimes.

Opportunities for woman-initiated HIV prevention methods among female sex workers in southern China

Rapid changes in China over the past two decades have led to significant problems associated with population migration and changing social attitudes, including a growing sex industry and concurrent increases in STIs and HIV. This article reports results of an exploratory study of microbicide acceptability and readiness and current HIV prevention efforts among female sex workers in two rural and one urban town in Hainan and Guangxi Provinces in southern China. The study focused on these women's knowledge and cultural understandings of options for protecting themselves from exposure to STIs and HIV, and the potential viability and acceptability of woman-initiated prevention methods. We report on ethnographic elicitation interviews conducted with women working within informal sex-work establishments (hotels, massage and beauty parlors, roadside restaurants, boarding houses). We discuss implications of these findings for further promotion of woman-initiated prevention methods such as microbicides and female condoms among female sex workers in China.     

Outlier detection and robust variable selection via the penalized weighted LAD-LASSO method

This paper studies the outlier detection and robust variable selection problem in the linear regression model. The penalized weighted least absolute deviation (PWLAD) regression estimation method and the adaptive least absolute shrinkage and selection operator (LASSO) are combined to simultaneously achieve outlier detection, and robust variable selection. An iterative algorithm is proposed to solve the proposed optimization problem. Monte Carlo studies are evaluated the finite-sample performance of the proposed methods. The results indicate that the finite sample performance of the proposed methods performs better than that of the existing methods when there are leverage points or outliers in the response variable or explanatory variables. Finally, we apply the proposed methodology to analyze two real datasets.
