中国在全球产品内分工体系中的地位及其变化动态
碧波
财贸经济 , 2013,
Abstract: 在全球产品内分工体系中,一国的要素禀赋结构决定着该国在其中的基本位置。在其他一些变量的共同作用下,一国在全球产品内分工体系中的位置在一定的时间段内也会发生某种程度的变动。本文基于参与模式、参与程度以及增值率三个维度的实证研究表明,中国目前仍处于全球产品内分工体系中的低端位置,但主动参与国际分工的领域不断扩展、承担的国际分工份额不断增加、参与国际分工的精细程度不断深化、加工增值率不断提高,这意味着中国正从全球产品内分工体系中的低端位置向两个高端位置方向迈进;但要占据或掌控全球产品内分工体系中的关键环节,中国需要依靠自有品牌及行业技术优势。
垂直专业化、全要素生产率与国际分工的参与模式————一个基于广东投入产出数据的“悖论”及其解释
碧波
中央财经大学学报 , 2014,
Abstract: ?分工日益精细化明显促进生产效率提高这一结论早已从理论逻辑的角度得到充分的论证,并且得到大量实证研究的支持。笔者基于广东投入产出数据的实证研究却表明,垂直专业化水平这一代表分工细化程度的影响变量对广东各主要行业的全要素生产率产生明显的负面效应。本文将这一实证“悖论”放在产品内国际分工的背景下进行详细的分析和解释,在此基础上依据要素禀赋结构提出我国参与国际分工的模式选择和政策建议。

论我国民族优惠的政策转向与话语重构
Policy turn and discourse reconstruction of ethnic minority preference in China

碧波
- , 2016, DOI: 1672-3104(2016)04-0137-06
Abstract: 摘 要: 我国是一个民族二元结构相对突出的多民族国家。为了实现少数民族与主体民族均衡协调的发展,我国实施了以“民族身份”作为社会资源倾斜性分配依据的民族优惠政策,在很大程度上促进了少数民族整体性发展。然而,随着时代变迁和社会嬗变,民族优惠政策的外溢效应渐趋凸显,民族优惠政策的存废也引发了学术界激烈而持久的思想交锋。事实上,由于我国民族二元结构在当前依然缺乏实质性改观,民族优惠政策仍然具有生存和发挥作用的空间。不过,鉴于民族优惠政策效力递减的客观现实,我国也应该逐渐以“区域主义”和“位差主义”的扶助政策替代“民族身份”取向的民族优惠政策,并通过重构“民族优惠”的话语体系,推动各民族形成“民族互惠”的中华民族共同体意识。
Abstract: China boasts of multi ethnic minorities with remarkable binary structure. In order to realize the balanced development between the ethnic minorities and majority, our country implements ethnic minority preferential policies with ethnic identity as the standard in allocating social resources inclinedly, which promotes their holistic development. However, with the development of the age and evolution of the society, the spillover effect of ethnic minority preferential policies began to highlight, arousing in academia heated and long-lasting controversy over its maintaining or abolishing. In fact, there is still much room for such policies to survive and develop because there still lacks critical change in the binary structure in our ethinicity. But, in view of the spillover effect of the ethnic minority preferential policies, we should turn gradually from the ethnicity-oriented preferential policies to difference-oriented support policies such as regionalism and difference discipline, and reconstruct the discourse system of national preference to promote the awareness of Chinese ethnic community that all ethnic groups form national reciprocity
论我国民族事务治理中的身份固化与边界跨越――兼论少数民族权利保护的思路转换
Solidification of ethnic identity and the crossing of ethnic boundary in ethnic affairs governance in China

Abstract: 摘 要: 民族身份识别是我国民族事务治理的一个原点。民族身份识别及民族加权极大地促进了各民族的包容性发展,但也容易诱致民族身份固化和族际边界切割。此外,民族身份信息的非规范采集和使用也激化着民族身份认同和刺激着民族边界凸显。有鉴于此,当前民族事务治理必须强化各民族的公民身份认同和中华民族认同、规范民族身份信息采集、允许民族成员个体拥有多元民族类别的身份,强化民族身份的个人自抉、解绑民族身份与权利附加之间的关联。在民族边界跨越的后时代,我国更加应该从区域分化、社会分化和少数人的角度,强化边疆区域、弱势群体和少数群体的权利保障,以达到不谈民族权利特殊化保障而实现民族权利特殊化保障之目的。
Abstract: Ethnic identification is the foundation of ethnic affairs governance in China. Ethnic identification and ethnic preferences greatly promote the balanced development of all ethnic groups, but they also tend to solidify the identity of ethnic groups and dissect the boundary among ethnics. Besides, non-normative collection and use of the information of ethnic identification sharpens ethnic identity and stimulates ethnic boundary. Given this, ethnic affairs governance at the present must strengthen citizens' identification and their identity as Chinese, regulate the collection of information of ethnic identity, allow ethnic individuals to hold multi-ethnic identity, foster individual's choice of ethnic identity, and unbind the connection between ethnic identity and rights addition. In the post-era of transcending ethnic boundary, our country should strengthen the guarantee of rights in border areas, disadvantaged groups, and minorities from the perspective of regional, social and minority distinctions so as to realize the guarantee of ethnic rights specialization without talking about ethnic rights specialization

Abstract: 目的 检测亲环素A(CypA)在胃癌组织和细胞株中的表达情况,采用基因干扰技术抑制胃癌细胞中CypA的表达,探讨CypA对胃癌细胞增殖能力的影响和相关分子机制。方法 实时定量PCR和蛋白质印迹法检测CypA在胃癌组织、癌旁组织和细胞株中的表达;合成针对CypA的靶向siRNA并转染胃癌MKN45细胞株,检测CypA-siRNA对胃癌细胞内源性CypA的抑制作用,同时设置非特异性siRNA对照组和阴性对照组。MTT法检测各组细胞增殖情况,流式细胞术检测各组细胞周期;实时定量PCR和蛋白质印迹法检测各组细胞增殖基因PCNA、P21、P16、Cyclin D1的表达。结果 胃癌组织中CypA的mRNA和蛋白表达高于癌旁组织,胃癌细胞株CypA的mRNA和蛋白表达高于胃上皮细胞株,且在低分化细胞MKN45中表达最高(P<0.05)。CypA-siRNA可有效抑制内源性CypA的表达;CypA-siRNA转染后MKN45细胞增殖能力下降(P<0.05),G0/G1期细胞比例上升、G2/M期细胞比例下降(P<0.05),PCNA、Cyclin D1的mRNA和蛋白表达下调,P21 mRNA和蛋白表达上调(P<0.05)。结论 胃癌细胞中CypA的表达增强,CypA基因能够通过调节部分增殖基因的表达而促进胃癌细胞增殖。
Objective To examine the expression of cyclophilin A (CypA) in gastric cancer tissues and cell lines, and to explore the effect and mechanism of CypA on the proliferation of gastric cancer cells. Methods Real-time quantitative PCR and Western blotting analysis were used to detect the expression of CypA in gastric cancer tissues, the corresponding adjacent tissues and gastric cancer cell lines. Small interfering RNAs targeting CypA were synthesized and transfected into the gastric cancer cell line MKN45. The effect of CypA-siRNA on endogenous CypA expression was observed; meanwhile, nonspecific siRNA control group and negative control group were also designed. Cell proliferation was measured with MTT assay in each group; cell cycle was detected with flow cytometry. The expression of PCNA, P21, P16, and Cyclin D1 gene, involved in cell proliferation, were also detected by real-time quantitative PCR and Western blotting analysis. Results CypA expression was significantly up-regulated in gastric cancer tissues compared with para-cancer tissues; and CypA expression in gastric cancer cell lines was also significantly higher than that in the gastric epithelial cell line GES-1, with the highest expression found in the poorly-differentiated gastric cancer cell line MKN45(P<0.05). The expression of CypA was significantly inhibited by the CypA-siRNA in MKN45 (P<0.05).MTT assay showed that the inhibition of CypA by CypA-siRNA significantly suppressed MKN45 cell proliferation (P<0.05). The ratio of G0/G1 phase cells was significantly increased in MKN45 cells after CypA-siRNA transfection, while the ratio of G2/M phase was significantly decreased(P<0.05). In addition, the expression of PCNA, Cyclin D1 was significantly decreased at mRNA and protein levels when CypA was inhibited, and the expression of P21 was significantly increased (P<0.05). Conclusion CypA is overexpressed in gastric cancer cells; CypA gene can effectively promote gastric cancer cell proliferation by regulating

Abstract: 目的 分析胃癌患者外周血Vav1基因D324Y位点多态性及白细胞介素 - 6(IL - 6)、肿瘤标志物的关系,对其意义进行探讨。方法 选取2013年1月 - 2015年12月确诊胃癌的患者300例为病例组,同时取100例体检健康者为对照组。化学发光法测定血清肿瘤标志物CA199水平;酶联免疫法(ELISA)检测外周血Vav1及IL - 6水平;直接测序技术检测Vav1基因D324Y位点多态性情况。结果 病例组外周血中Vav1、CA199、IL - 6水平均高于对照组(P<0.05)。病例组中Vav1基因D324Y位点TT、GT的基因型频率分别为7.0%、19.3%,高于对照组(0%、5.0%)(P<0.05);病例组中T等位基因的频率为16.67%,高于对照组(2.5%)(P<0.05)。两因素方差分析结果显示,IL - 6、CA199、Vav1的水平与患病状态及基因型均有关系(P<0.001)。Logistic回归结果显示TT基因型与胃癌关系密切,是胃癌的独立危险因素(P<0.05)。结论 Vav1基因D324Y位点多态性可能是胃癌发生进展的重要影响因素。
理论信息学基础上的信息心理学
Informational Psychology Based on Theoretical Informatics
 [PDF]

李宗荣, 谢涵,碧波
Advances in Psychology (AP) , 2016, DOI: 10.12677/AP.2016.64063
Abstract:
随着理论信息学的产生和发展,完整的信息科学知识体系建立起来,信息科学世界观为各个人文社会科学学科提供了全新的视角。信息科学的世界观认为,与宇宙万物一样,人类心理现象也具有物质和信息两种属性;关于这两种属性的研究成果分别构成物质心理学与信息心理学;它们是整个心理学体系的两个主要的分支。物质心理学的研究对象是心理现象的生物载体,采用经验观察、数量分析与公式表达的方法;信息心理学研究对象是心理现象的信息特征,采取内心体验、逻辑分析与程序表达的方法。构成信息心理学的基本知识包括:人是一个开放的、自组织的生理与心理系统;人的本质是一个信息复制与生成系统;人的心理系统的基本组成元素包含动机、知识和智慧;人类信息处理包含从感觉到思维的九大基本功能;全部心理信息研究的主导与核心是人类智能的涌现机制。信息心理学应用的初步成果,首先是分析当代心理学的现状、困境和出路,得到了关于心理学的学科性质、理论前提、研究对象、研究方法的新认识;然后,它提出了从整体上把握心理学的历史、现状及未来的新思路。在可以预见的未来,信息心理学不仅对现有的理论心理学、基础心理学以及应用心理学进行补充,而且为现有心理学主流和边缘的统一与整合提供新的基本概念和理论框架。
With the emergence and development of theoretical informatics, a complete information science system is set up, which provides a fresh perspective for various social sciences. In the point of in-formation science, material property and informational property are two attributes of human psychological phenomena like everything in the universe. Studies of these two attributes constitute material psychology and informational psychology respectively. These two psychologies are main branches of the whole psychological system. The research object of material psychology is the biological carrier of psychological phenomena, and the methods of empirical observation, quantitative analysis, and formula expression are used; the research object of informational psy-chology is the characteristics of psychological phenomena, and the methods of inner experience, logical analysis, and program expression are used. In the knowledge hierarchy of informational psychology: human is an open and self-organized material and psychological system; the nature of human is an information duplicating and generating system; the basic elements which consist of human’s psychological system are motivation, knowledge, and wisdom; human information processing includes nine basic functions which vary from feeling to thinking; and the dominance and core of all researches of psychological information are the emergence mechanism of human intelligence. The application of informational psychology has gained preliminary achievements. At first, people get some new viewpoints in the subject nature, theoretical precondition, research objects, and methods of psychology through analyzing the contemporary psychology’s current situation, difficulties, and solutions. Then informational psychology suggests a new train of thought which is grasping the history, current situation, and future of psychology as a whole. Informational psychology complements the theoretical psychology, basic psychology, applied
