信息社会的本质是能够产生个人信息法律关系,信息流是解构个人信息法律关系的关键,也是个人信息法律关系产生的直接动力.个人信息法律关系的主流构造分别以信息自决、隐私和人格权益为基础,其中,国家利益成为个人信息法律关系构造中不可忽视的力量.三种构造模式分别体现出个人与企业,个人与国家,个人、企业和国家三者之间的利益平衡.由于利益平衡体现出的幸存者偏差效应,个人信息法律关系的构造以主体场域信息自治为中心,具有合理性和现实性.  相似文献

几乎每个国家对进口产品包装是否有益于国民身体健康,以及是否有益于生态环境都有严格的规定和标准.在理论分析包装绿色壁垒对企业出口影响的基础上,选取2003-2018年荣成富邦制笔有限公司出口产品均价、数量等时间序列数据,运用虚拟变量模型进行实证分析.研究发现,虽然随着时间的不同而存在差异,但包装绿色壁垒对企业出口有显著的阻碍作用.因此,建议通过转移目标市场、调整产品结构、提高生产效率、建立预警和协调机制来应对包装绿色壁垒,提升企业出口.  相似文献

文化是人类活动的深层心理结构,东亚文化是东亚地区青少年设计创造力培养的重要影响因素。东亚文化以儒家思想为核心,有其鲜明特点,深深影响着东亚教育观、教师观、家庭观以及价值观。文化创新是青少年设计创造力培养的推动剂,加强东亚文化创新建设,应采用树立鼓励创造的教育观、培养热爱创新教育的教师、营造非权威的家庭环境、内化青少年创新价值观等创新策略,有效促进青少年设计创造力的发展。  相似文献

缅北动荡局势下,我国中缅边境地区面临传统安全与非传统安全双重威胁。从前期系列缅北冲突导致的问题处理经验看,我国中缅边境地区安全应对体系建设在预防意识的主动性、应急制度的协调性、应急体系的系统性方面仍有待进一步提升。立足中缅边境地区安全问题的特殊性,其应对可从立足跨境民族众多的实情主动应对、立足边境安全事件的复杂性系统应对、立足边疆经济的落后性持续应对等方面予以加强。  相似文献

The present study examines the cyberpsychology of blog readership as well as the digital content preferences of the Millennial generation by examining the links between college students’ personality traits, motivations to read blogs, and preferred blog features. Results indicate that personality influences motivations for reading blogs, which in turn helps predict perceived importance of blog characteristics. Notably, extraversion and neuroticism were related to reading blogs for social interaction; extraversion negatively predicted use of blogs to meet identity needs; openness was related to blog reading for entertainment purposes; and conscientiousness was positively associated with information seeking via blogs. Additionally, motivations for blog readership as explanatory mechanisms for the relationships found between personality traits and perceived importance of blog features are discussed.  相似文献

In the 1960s and 1970s, the countries of Central and Eastern Europe and the Soviet Union experienced an unanticipated stagnation in the process of mortality reduction that was accelerating in the west. This was followed by even starker fluctuations and overall declines in life expectancy during the 1980s and 1990s. We identify statistically the extent to which, since the 1990s, the countries of the post-communist region have converged as a group towards other regional or cross-regional geopolitical blocks, or whether there are now multiple steady-states (‘convergence clubs’) emerging among these countries. We apply a complex convergence club methodology, including a recursive analysis, to data on 30 OECD countries (including 11 post-communist countries) drawn from the Human Mortality Database and spanning the period 1959–2010. We find that, rather than converging uniformly on western life expectancy levels, the post-communist countries have diverged into multiple clubs, with the lowest seemingly stuck in low-level equilibria, while the best performers (e.g. Czech Republic) show signs of catching-up with the leading OECD countries. As the post-communist period has progressed, the group of transition countries themselves has become more heterogeneous and it is noticeable that distinctive gender and age patterns have emerged. We are the first to employ an empirical convergence club methodology to help understand the complex long-run patterns of life expectancy within the post-communist region, one of very few papers to situate such an analysis in the context of the OECD countries, and one of relatively few to interpret the dynamics over the long-term.  相似文献

This paper presents a simple and robust method for obtaining a comprehensive understanding of the joint period and radius distribution in Kepler exoplanets. The proposed method is based on particle swarm optimization and bivariate Normal Inverse Gaussian distribution. Furthermore, in the construction of the probability density function, this study selects planet-host stars with the GK-type. The injecting approach is also employed to solve the survey completeness of sample. The resulting occurrence rate of Earth analogs is 0.025 with a 95% bootstrap confidence interval between 0.023 and 0.032.  相似文献

From the economical viewpoint in reliability theory, this paper addresses a scheduling replacement problem for a single operating system which works at random times for multiple jobs. The system is subject to stochastic failure which results the imperfect maintenance activity based on some random failure mechanism: minimal repair due to type-I (repairable) failure, or corrective replacement due to type-II (non-repairable) failure. Three scheduling models for the system with multiple jobs are considered: a single work, N tandem works, and N parallel works. To control the deterioration process, the preventive replacement is planned to undergo at a scheduling time T or the job's completion time of for each model. The objective is to determine the optimal scheduling parameters (T* or N*) that minimizes the mean cost rate function in a finite time horizon for each model. A numerical example is provided to illustrate the proposed analytical model. Because the framework and analysis are general, the proposed models extend several existing results.  相似文献
