Dispersal patterns exhibited by group-living animals play an important role in individual reproductive success and survival, as well as population and social dynamics （Greenwood, 1980; Isbell and van Vuren, 1996; Kappeler and van Schaik, 2002）. Dispersing individuals may emigrate voluntarily, or they may be forcibly evicted by other individuals （Pusey and Packer, 1987; Clobert et al. , 2001 ）. One cause of individual dispersal is when an extra-group male compels another male to leave a group of females. This phenomenon has been well documented in primates, especially Old World monkey species （ e.g. Colobus vellerosus ： Saj and Sicotte, 2005 ; Erythrocebus patas ： Ohsawa, 2003 ; Macaca fascicularis ： van Noordwiik and van Schaik, 2001）.

What is the most favorite and original chemistry developed in your research group? Vitamin B6-based biomimetic asymmetric catalysis. How do you get into this specific field? Could you please share some experiences with our readers? Enzymatic transformations are characterized by high efficiency, specific selectivities, and mild conditions, which attracts me to do some chemistry related to biological systems.

利率市场化是建设社会主义市场经济体制、发挥市场配置资源作用的重要内容,是加强我国金融间接调控的关键,是完善金融机构自主经营机制、提高竞争力的必要条件。因此,稳步推进利率市场化已成为我国下一步深化金融改革的重要任务之一。通过积极寻求有关利率市场化的理论依据并科学借鉴已实施利率市场化国家和地区的经验,对于提出我国利率市场化的具体实施思路以及客观分析当前所需外部条件具有十分重要的意义。在当前利率市场化的思路和方案已经基本明晰的前提下,当务之急是积极创造条件以推进利率市场化改革的进程,防范和化解利率市场化进程中蕴藏的各种风险。

文章针对商业信用扭曲困境,以政府规制为切入点,通过构建演化博弈模型分析了数字技术对政策执行企业和受困企业商业信用策略的影响和作用机制。研究发现:首先,违约受惩力度和守约所获潜在收益影响两个主体的行为策略;其次,政府规制成本以及政策执行企业检测成本直接影响违约检测率,导致系统不能够达到长期均衡稳定。智能区块链通过降低信用风险和提高违约成本,能够有效化解系统不能长期稳定的状态,实现政府规制和企业策略之间的守恒,破解商业信用扭曲的困境。
