论社会主义市场经济的三个根本问题

坚持和发展社会主义市场经济,必须紧紧抓住和解决好基本制度、生产目的和资源配置这三个根本问题.这三个根本问题也构成了中国特色社会主义政治经济学的核心内容.在基本制度方面,必须坚持公有制主体地位不能动摇,国有经济主导作用不能动摇;坚持按劳分配为主体、使改革发展成果更多更公平惠及全体人民.在生产目的上,要满足广大人民日益增长、不断升级和个性化的物质文化和生态环境需要.在解放和发展生产力的同时,保证被解放和发展了的生产力归人民所有,走可持续发展道路.在资源配置方面,社会主义国家由于有公有制经济的全力配合,政府对资源配置才能真正发挥“看得见的手”的作用,当然其效果如何还得看这只手有没有遵循经济发展的客观规律.中国特色社会主义追求的是共同富裕,公有制的存在和发展保证了经济发展成果由人民群众共享,从而中国特色社会主义的效率必然是也必须是最广大人民群众的效率,从而这个效率必然是与公平一致的.     

就近半城市化与去城市两级分化

农民以家庭为单位普遍选择的就近半城市化路径中,人口迁徙具有可逆性：一是从城市回流到农村的可逆性,二是从大城市回流到中小城市的可逆性。这两种可逆性勾勒着我国城市化进程中的“去城市两极分化”机制：类贫民窟作为物理载体仍然会在城市化的过程中存在,但在可逆过程中,它并不会形成一个刚性的城市社会贫民阶层,进而这种可逆性成为城市社会两极分化结构中的弹性要素;特大城市也会产生,但在可逆的过程中,作为纯资源接受者的中小城市将获得人口集聚和经济发展的契机,从而这种可逆性也构成了城市体系两极分化结构中的弹性要素。     

习近平治国理政的哲学方法论探略

党的十八大以来,以习近平同志为核心的党中央立足当代中国、把握世界大势,提出了一系列治国理政的新理念新思想新战略,有力推动中国特色社会主义进入新时代,形成了习近平新时代中国特色社会主义思想。习近平总书记高度重视学习和掌握辩证唯物主义和历史唯物主义,将其视为中国共产党人的“看家本领”。马克思主义哲学为习近平治国理政提供了总的方法论遵循。辩证唯物主义特别是其中的实事求是的实践观、事物联系发展的观点、具体问题具体分析的矛盾观提供了思维方法的总依据;历史唯物主义关于人民主体地位的思想和群众路线群众观点则贯穿于其治国理政全过程,彰显着中国共产党的价值自觉、理论自觉与实践自觉,奠定了习近平治国理政新理念新思想新战略的整个基石。     

中小学教师依法治教的困境与对策

中小学教师是依法治教的实践者、宣讲者、推动者,是推动依法治教的关键因素之一。但是,在中小学教师依法治教的过程中,还存在着中小学教师法治素养良莠不齐,教育立法滞后、执法不严、司法不公以及中小学教师职前、职后法治教育缺失等现象。全面推进依法治国,实现教育治理体系和治理能力现代化,必须深刻把握和充分发挥中小学教师在依法治教中的价值和作用,增强其依法治教的自觉性;必须深刻分析中小学教师在依法治教中面临的各种困境与原因,采取针对性措施,做到有的放矢,综合施策。     

拟人绘本和真人绘本对幼儿人格教育效果的影响： 一项挑战传统观念的国外心理学实验的启示

绘本阅读是幼儿成长过程中的一种有效教育途径。绘本中的角色类型会影响绘本对幼儿的教育效果。笔者基于国外一项心理学实验,并结合其他相关实验,介绍拟人绘本和真人绘本对幼儿人格和知识学习影响的研究,从幼儿心理学角度分析了真人绘本在教育效果上优于拟人绘本的心理机制。最后,阐述了关于拟人绘本和真人绘本的几点思考。     

习近平新时代中国特色社会主义思想认同机制研究

促进人民群众对习近平新时代中国特色社会主义思想的认同,是当前重大理论和实践问题.而构建动力机制、健全引导机制、完善保障机制有利于强化对习近平新时代中国特色社会主义思想的认同.构建动力机制,需要以实现中华民族伟大复兴的中国梦激发认同的情感动力,以让人民群众有更多获得感、幸福感、安全感增强认同的利益动力,以理论的科学性增加认同的思想动力;健全引导机制,需要以理论研究为支撑,完善教育机制;以正确舆论为导向,强化宣传机制;以阵地建设为平台,健全导向机制;完善保障机制,需要壮大经济基础,突出利益认同;健全民主政治,增强政治认同;坚持文化自信,强化价值认同;夯实民生基础,巩固社会认同;推进绿色发展,提升生态认同.     

Assessing Risk‐Based Upper Limits of Melamine Migration from Food Containers

Melamine contamination of food has become a major food safety issue because of incidents of infant disease caused by exposure to this chemical. This study was aimed at establishing a safety limit in Taiwan for the degree of melamine migration from food containers. Health risk assessment was performed for three exposure groups (preschool children, individuals who dine out, and elderly residents of nursing homes). Selected values of tolerable daily intake (TDI) for melamine were used to calculate the reference migration concentration limit (RMCL) or reference specific migration limit (RSML) for melamine food containers. The only existing values of these limits for international standards today are 1.2 mg/L (0.2 mg/dm²) in China and 30 mg/L (5 mg/dm²) in the European Union. The factors used in the calculations included the specific surface area of food containers, daily food consumption rate, body weight, TDI, and the percentile of the population protected at a given migration concentration limit (MCL). The results indicate that children are indeed at higher risk of melamine exposure at toxic levels than are other groups and that the 95th percentile of MCL (specific surface area = 5) for children aged 1–6 years should be the RMCL (0.07 mg/dm²) for protecting the sensitive and general population.     

Tibetan minzu market: the intersection of ethnicity and commodity

In downtown Chengdu a pocket of Tibetan culture has sprung up: a Tibetan market where Tibetans and Han Chinese meet to buy and sell ethnic minority products. Pointing to how Tibetan migration to Chengdu has contributed to the growth of a vibrant ‘minzu market’ attracting Tibetan and Han Chinese merchants, customers, Buddhist devotees, and voyeurs, this article presents novel understandings of the ethnic goods market in urban Chengdu. The article first explores the growth of the market, which is the result of a history of political and economic reforms, increased mobility, and religious revival. Second, it maps the market infrastructure according to the ethnicity of the shopkeepers and the commodities that are traded. Although there is still a clear ethnic division in the market, this article also documents the emergence of Han Chinese market participation in forms of trade that have historically been dominated by Tibetans.     

Žumberak: A Sixteenth-Century Refugee Settlement Zone

This article examines the movement of Orthodox Christian refugees from Bosnia to the Habsburg Monarchy in the 1530s and their settlement in a district called ?umberak. The movement of these Uskoks has never been examined in the context of refugee studies. This study of a refugee movement and settlement over a five-century period offers the possibility of reaching a better understanding of the long-term outcome of refugee movements. Ultimately, this article suggests that the refugees affected the land they settled as much as the settlement zone affected them, and that, in this case, the refugees were able to define their own outcome.     

The empirical Bayes estimators of the parameter of the Poisson distribution with a conjugate gamma prior under Stein's loss function

For the hierarchical Poisson and gamma model, we calculate the Bayes posterior estimator of the parameter of the Poisson distribution under Stein's loss function which penalizes gross overestimation and gross underestimation equally and the corresponding Posterior Expected Stein's Loss (PESL). We also obtain the Bayes posterior estimator of the parameter under the squared error loss and the corresponding PESL. Moreover, we obtain the empirical Bayes estimators of the parameter of the Poisson distribution with a conjugate gamma prior by two methods. In numerical simulations, we have illustrated: The two inequalities of the Bayes posterior estimators and the PESLs; the moment estimators and the Maximum Likelihood Estimators (MLEs) are consistent estimators of the hyperparameters; the goodness-of-fit of the model to the simulated data. The numerical results indicate that the MLEs are better than the moment estimators when estimating the hyperparameters. Finally, we exploit the attendance data on 314 high school juniors from two urban high schools to illustrate our theoretical studies.
