通过科学立法促进民族交往交流交融的法理探讨

在中华民族“多元一体”背景下,加强各民族交往交流交融,是铸牢中华民族共同体意识的必然要求。而通过科学立法建立完备的法律规范体系,则是运用法治思维和法治方式,促进各民族交往交流交融的根本前提。当前我国的民族法律规范体系虽已基本建成,但仍存在一些法律原则的表达不够严谨、法律概念的界定不够准确、法律规则的内容不够明晰和完整、规范体系的结构不够完备和和谐等缺陷和不足,难以满足在政治、经济、文化、社会和生态建设中通过法治方式有效协调民族关系,促进各民族交往交流交融的需要。这就要求立法者应遵循《立法法》确定的科学立法的形式合理性和实质合理性的要求,妥善处理法律规范体系与现实需要的适应性和可执行性,由此才能为通过法治促进各民族交往交流交融奠定坚实的制度基础。从科学立法与依法立法、民主立法的关系来看,遵循依法立法,是保障法的形式合理性的前提;坚持民主立法,则是保障法的实质合理性的根基。为提升立法的科学品质,必须健全违宪审查机制、协商民主机制和立法理论形成机制,确保依法立法、民主立法原则的有效落实。

广西沿边"适应-竞争-合作"式 城镇演化模式研究 ——以凭祥、东兴为例

新时代不充分不平衡发展问题突出,加大力度支持边疆民族地区加快发展的要求迫在眉睫。广西沿边民族地区发展总体滞后,城镇发展模式趋同;东兴和凭祥在沿边城镇发展模式趋同的情况下,在“适应-竞争-合作”式城镇演化过程中,充分利用国家政策、发挥比较优势、培育优势特色产业、深化内外合作,实现了城镇经济的跨越式发展。本文以生物学“趋同进化”理论为基础,结合新发展理念和东兴、凭祥的发展经验建议：广西沿边民族地区采取“适应-竞争-合作”式城镇发展模式,以创新增强各城镇内生动力,以互补合作促进协调发展,以绿色发展道路助推城镇发展的可持续性,以加强内外市场的联动性来深化城镇开放、合作式发展,以“省-市-县”、“县-镇-村”的互联互通推进共享发展。     

Leadership,creativity, and innovation: A critical review and practical recommendations

Leadership is a key predictor of employee, team, and organizational creativity and innovation. Research in this area holds great promise for the development of intriguing theory and impactful policy implications, but only if empirical studies are conducted rigorously. In the current paper, we report a comprehensive review of a large number of empirical studies (N?=?195) exploring leadership and workplace creativity and innovation. Using this article cache, we conducted a number of systematic analyses and built narrative arguments documenting observed trends in five areas. First, we review and offer improved definitions of creativity and innovation. Second, we conduct a systematic review of the main effects of leadership upon creativity and innovation and the variables assumed to moderate these effects. Third, we conduct a systematic review of mediating variables. Fourth, we examine whether the study designs commonly employed are suitable to estimate the causal models central to the field. Fifth, we conduct a critical review of the creativity and innovation measures used, noting that most are sub-optimal. Within these sections, we present a number of taxonomies that organize extant research, highlight understudied areas, and serve as a guide for future variable selection. We conclude by highlighting key suggestions for future research that we hope will reorient the field and improve the rigour of future research such that we can build more reliable and useful theories and policy recommendations.     

我国创业板市场的设立和风险投资退出机制

风险投资对于经济的增长尤其是高新技术的发展有非常重要的意义。而风险投资能够适时地成功退出,是其良好发展的关键。通过分析风险投资退出机制发现,我国新推出的创业板市场较低的上市条件．使风险投资更容易变现和退出。风险投资的不断发展,为创业板市场培育出优秀的上市资源。将创业板市场与风险投资退出机制结合,相辅相成,可以促进风险资金良性循环。     

试论健美操运动对大学生树立终身体育观的影响

高校体育作为学校体育教育的最高层次和最后环节,是学校体育与体育社会化的转折点和学与用的衔接点。因此对大学生来说终身体育教育是我国高校体育教育的重要课题之一。健美操运动不仅能全面锻炼身体的各个部位,更能培养大学生自觉运动的能力和习惯,从而影响他们,使之形成终身体育的观念。     

Critical Infrastructure Vulnerability to Spatially Localized Failures with Applications to Chinese Railway System

This article studies a general type of initiating events in critical infrastructures, called spatially localized failures (SLFs), which are defined as the failure of a set of infrastructure components distributed in a spatially localized area due to damage sustained, while other components outside the area do not directly fail. These failures can be regarded as a special type of intentional attack, such as bomb or explosive assault, or a generalized modeling of the impact of localized natural hazards on large‐scale systems. This article introduces three SLFs models: node centered SLFs, district‐based SLFs, and circle‐shaped SLFs, and proposes a SLFs‐induced vulnerability analysis method from three aspects: identification of critical locations, comparisons of infrastructure vulnerability to random failures, topologically localized failures and SLFs, and quantification of infrastructure information value. The proposed SLFs‐induced vulnerability analysis method is finally applied to the Chinese railway system and can be also easily adapted to analyze other critical infrastructures for valuable protection suggestions.     

An optimal online algorithm for the parallel-batch scheduling with job processing time compatibilities

We consider the online (over time) scheduling on a single unbounded parallel-batch machine with job processing time compatibilities to minimize makespan. In the problem, a constant \(\alpha >0\) is given in advance. Each job \(J_{j}\) has a normal processing time \(p_j\). Two jobs \(J_i\) and \(J_j\) are compatible if \(\max \{p_i, p_j\} \le (1+\alpha )\cdot \min \{p_i, p_j\}\). In the problem, mutually compatible jobs can form a batch being processed on the machine. The processing time of a batch is equal to the maximum normal processing time of the jobs in this batch. For this problem, we provide an optimal online algorithm with a competitive ratio of \(1+\beta _\alpha \), where \(\beta _\alpha \) is the positive root of the equation \((1+\alpha )x^{2}+\alpha x=1+\alpha \).     

中国股市高阶矩风险及其对投资收益的冲击

本文首先建立NAGARCHSK模型,推算市场收益率的条件高阶矩序列,在此基础上建立引入高阶矩风险的收益-风险时变四因子状态空间模型,并基于2000-2016年中国股票市场的收益率数据,实证探究不同时期市场高阶矩风险对投资收益的冲击.结果显示:我国股票市场收益受到高阶矩风险的影响,并且条件高阶矩序列表现出时变和波动聚集的特征,大规模的全球性金融危机和国内市场的重大风险事件均会使股市收益的条件高阶矩序列出现持续的异常波动.在未出现极端金融危机的稳定时期,市场收益率的条件方差会趋于对投资收益产生正向影响,条件偏度和条件峰度对投资收益的影响在正向和负向之间不断交替,增加了投资收益的不确定性.然而在全球性的极端金融危机时期,市场收益率的条件方差会转而对投资收益产生负向影响,条件峰度则会对投资收益带来持续的正向影响.
