论广西转变经济发展方式新走向——从“工业兴桂”向“质量兴桂”转变

广西转变经济发展方式新走向是从＂工业兴桂＂向＂质量兴桂＂转变。在实施中要进一步解放思想;要加快转变经济增长方式,优化产业结构;要加快工业技术创新和技术改造,大力实施品牌发展策略;要充分发挥企业在＂质量兴桂＂战略中的主体作用;要建立健全质检监测平台,加强质量诚信体系建设,普及质量文化知识教育;要加强执法检查和质量安全监管;要加强宏观调控,系统管理;要切实加强＂质量兴桂＂战略实施的领导。     

浅析韩国的绿色增长战略

绿色增长正在成为世界谋求经济社会可持续发展的重要经济模式,各国都在寻求实现绿色增长的发展战略。1997亚洲金融风暴、2008年以来的世界性经济衰退促使积极探索经济转型新路的韩国加快了战略转型的步伐。韩国政府为此提出并开始实施“低碳绿色增长战略”,制订并发表了“绿色增长国家战略与五年计划”以及相关的法规,详细阐述了韩国推进这一战略计划的长远规划、战略目标、实施计划、政策措施等,并建立了从中央到地方的组织实施机构。韩国积极推动的绿色增长战略充分揭示了其未来经济发展的基本方向,意在谋求实现经济增长方式的转变、构建未来经济长期稳定发展的新增长模式和动力。     

铜对生长猪肝中IGF-Ⅰ基因mRNA表达的影响

采用生长试验、免疫放射分析和定量PCR方法,观察了生长猪血液中类胰岛素生长因子(IGF-I)及其结合蛋白(IGFBP3)数量的变化和IGF-I基因在肝中表达量的变化。结果显示, 每1 kg饲料中添加125-250 mg铜,能够上调IGF-I基因的表达量,显著提高猪的平均日增重,促进生长猪循环血液中IGF-I浓度的增加。试验结果证实,铜是通过促进生长激素-胰岛素样生长因子轴相关因子的合成和分泌来发挥促生长作用的。

文章评析当代市场经济国家在公司治理中出现的几种典型的公司治理结构模式,比较它们之间异同,进而分析我国国有企业、民营企业治理结构的现实状况,提出了我国公司治理结构的建立模式和具体的政策建议。     

关于循环经济理论与实践的思考

随着经济快速增长和人口增加,资源不足的矛盾越来越突出。中央宏观调控的一个重要目标就是重塑一个资源消耗低、环境污染少、经济效益好的国民经济体系,为建设资源节约型社会奠定基础。因此,2004年的中央经济工作会议高举发展循环经济大旗,发展循环经济被提到一个前所未有的战略高度。     

资源生产率视角的经济增长模型分析

现在的稀缺资源已从劳动和资本开始变为自然资源,但新古典经济学中的生产函数仍以资本和劳动为内生变量,而将自然资源作为外生变量。我们需要对新古典经济中的生产函数进行相应的修正,将自然资源外生变量内生化,将其作为生产函数中的内生变量来对生产函数进行重新研究。目前我国的单位GDP能耗与发达国家相比仍有较大差距,应从制度性安排与技术变革这两个层面上采取措施以提高资源生产率。     

THE CONTEXT OF MARRIAGE AND CRIME: GENDER,THE PROPENSITY TO MARRY,AND OFFENDING IN EARLY ADULTHOOD*

Marriage is central to theoretical debates over stability and change in criminal offending over the life course. Yet, unlike other social ties such as employment, marriage is distinct in that it cannot be randomly assigned in survey research to more definitively assess causal effects of marriage on offending. As a result, key questions remain as to whether different individual propensities toward marriage shape its salience as a deterrent institution. Building on these issues, the current research has three objectives. First, we use a propensity score matching approach to estimate causal effects of marriage on crime in early adulthood. Second, we assess sex differences in the effects of marriage on offending. Although both marriage and offending are highly gendered phenomena, prior work typically focuses on males. Third, we examine whether one's propensity to marry conditions the deterrent capacity of marriage. Results show that marriage suppresses offending for males, even when accounting for their likelihood to marry. Furthermore, males who are least likely to marry seem to benefit most from this institution. The influence of marriage on crime is less robust for females, where marriage reduces crime only for those with moderate propensities to marry. We discuss these findings in the context of recent debates concerning gender, criminal offending, and the life course.     

THE TWELVE PEOPLE WHO SAVED REHABILITATION: HOW THE SCIENCE OF CRIMINOLOGY MADE A DIFFERENCE

Three decades ago, it was widely believed by criminologists and policymakers that “nothing works” to reform offenders and that “rehabilitation is dead” as a guiding correctional philosophy. By contrast, today there is a vibrant movement to reaffirm rehabilitation and to implement programs based on the principles of effective intervention. How did this happen? I contend that the saving of rehabilitation was a contingent reality that emerged due to the efforts of a small group of loosely coupled research criminologists. These scholars rejected the “nothing works” professional ideology and instead used rigorous science to show that popular punitive interventions were ineffective, that offenders were not beyond redemption, and that treatment programs rooted in criminological knowledge were capable of meaningfully reducing recidivism. Their story is a reminder that, under certain conditions, the science of criminology is capable of making an important difference in the correctional enterprise, if not far beyond.     

Exploring Some Analytical Characteristics of Finite Mixture Models

Finite mixture models have become increasingly prevalent in criminology over the past two decades. Yet there is no consensus about the appropriate criterion for model selection with finite mixture specifications. In this paper, we use simulation evidence to examine model selection criteria. Our focus is on mixture models for event count data like those often encountered in criminology. We use two indices to measure model selection performance. First, we examine how often each criterion chooses the correct specification. Then, we investigate how closely the finite mixture models selected by these criteria approximate the true mixing distribution used to simulate the event count data. We consider three sets of simulations. In the first set, the underlying model is itself a three component Poisson-based finite mixture model. In the two other sets of simulations, the underlying distribution of the Poisson rate parameter follows a continuous distribution. The analysis shows that both AIC and BIC perform well under certain sets of circumstances likely to be encountered by criminologists.
