互联网金融背景下大学生消费观的培养

高校大学生是互联网金融消费的重要年轻群体,因其巨大的消费潜力,众多互联网金融行业更是将其作为关键的目标客户。互联网金融在给大学生提供便利、缓解小额资金短缺的同时,还带来了重物质型消费、攀比心理和从众心理凸显等诸多问题。在良莠不齐、复杂多变的互联网消费背景下,政府、高校、家庭三者必须齐心协力,对大学生群体进行消费观教育,帮助大学生养成科学的消费理念,自觉抵御不良消费行为。     

Olivine-norite rock detected by the lunar rover Yutu-2 likely crystallized from the SPA-impact melt pool

Chang’E-4 landed in the South Pole-Aitken (SPA) basin, providing a unique chance to probe the composition of the lunar interior. Its landing site is located on ejecta strips in Von Kármán crater that possibly originate from the neighboring Finsen crater. A surface rock and the lunar regolith at 10 sites along the rover Yutu-2 track were measured by the onboard Visible and Near-Infrared Imaging Spectrometer in the first three lunar days of mission operations. In situ spectra of the regolith have peak band positions at 1 and 2 μm, similar to the spectral data of Finsen ejecta from the Moon Mineralogy Mapper, which confirms that the regolith''s composition of the landing area is mostly similar to that of Finsen ejecta. The rock spectrum shows similar band peak positions, but stronger absorptions, suggesting relatively fresh exposure. The rock may consist of 38.1 ± 5.4% low-Ca pyroxene, 13.9 ± 5.1% olivine and 48.0 ± 3.1% plagioclase, referred to as olivine-norite. The plagioclase-abundant and olivine-poor modal composition of the rock is inconsistent with the origin of the mantle, but representative of the lunar lower crust. Alternatively, the rock crystallized from the impact-derived melt pool formed by the SPA-impact event via mixing the lunar crust and mantle materials. This scenario is consistent with fast-cooling thermal conditions of a shallow melt pool, indicated by the fine to medium-sized texture (<3 mm) of the rock and the SPA-impact melting model [Icarus 2012; 220: 730–43].     

风险投资与政府补贴对新材料企业技术创新的激励效应及差异

随着近年资源应用领域逐步向高新技术产业延伸,下游材料端的技术创新突破已成为重构中国资源产业优势的战略着力点。本文利用2008—2017年中国新材料企业面板数据,运用PVAR模型和脉冲响应函数,从技术生命周期视角探究了风险投资与政府补贴对中国新材料企业技术创新的激励效应及其差异性。研究表明：①对于新材料企业,风险投资和政府补贴通过提升企业研发投入进而促进了新材料企业的技术创新。其中,风险投资的激励效应更明显但具有短期性,政府补贴的激励效应则具有滞后性;②对于导入期新材料企业,风险投资对其技术创新的激励效应较小,而政府补贴正好弥补了市场资金配置的不足;对于成长期新材料企业,风险投资对其技术创新的长期激励效应强于政府补贴;对于成熟期新材料企业,政府补贴不能促进其技术创新,风险投资的激励效应则比较显著。因此,为更好地提升中国新材料技术创新水平,政府应引入分类补贴机制,重点向导入期新材料企业倾斜,并引导风险资本投入成长期和成熟期新材料企业。     

黄河流域农村饮水安全问题及对策

21世纪以来中国农村饮水安全工程建设取得重大成就,截至2018年底,全国农村自来水普及率已达到80%以上,解决了绝大多数农村人口的安全饮水问题。然而黄河流域部分农村地区水资源短缺、水源水质差、饮水型地方病危害重、饮用水水源地缺乏保护和农村饮水安全工程不完善等问题突出,饮水安全保障工作相对于全国农村饮水安全工程进程较为滞后。为切实解决黄河流域农村人民群众的饮水安全问题,促进黄河流域生态保护和高质量发展,本文综述了目前黄河流域饮水安全突出的问题,并结合全国农村饮水提质增效的工作目标,提出了进一步做好流域内农村饮水安全工作的建议,包括实现水资源动态配置、加强饮水安全设施建设和工程管理、强化水源地保护与监测等,从优先保障饮用水水量和水质方面全面维护流域内农村地区的饮水安全。     

The effects of labeling bias on prognostic outlook for children as a function of diagnostic label and profession

Labeling bias refers to expectations that others might have for a person given a particular label. This study investigated the effects of labeling bias on prognostic outlook for children as a function of diagnostic labels and professional group membership. School psychologists, regular and special education teachers, and introductory psychology students read a vignette that described an elementary-school-aged boy with behavior problems. The vignette was held constant for all participants, but one of four labels (conduct disordered, socially maladjusted, serious emotionally disturbed, no exceptionality) was varied at the end of the vignette. Respondents then estimated the child's likelihood of future success in interpersonal relationships, the likelihood of further behavioral difficulties, and overall adjustment of the child. There was a significant effect noted for diagnostic label across all professionals on the interpersonal relations variable; the serious emotionally disturbed label resulted in judgments of significantly poorer outlook than any other diagnostic label except socially maladjusted. There were no other significant labeling bias effects for the other dependent measures, but a main effect for diagnostic label on judgment of overall adjustment did approach significance. There were no significant effects noted for professional group membership. Professionals should consider the use of a label other than SED to minimize labeling bias effects on judgment of interpersonal adjustment in children with behavioral difficulties. © 1996 John Wiley & Sons, Inc.     

可卡因管制在反兴奋剂实践中的探析：以2021年实施版《世界反兴奋剂条例》为例

2021年实施版《世界反兴奋剂条例》在第五届世界反兴奋剂大会上正式获得通过,并将于2021年1月1日起正式生效。新版条例有关可卡因的规定变化颇多。对可卡因是否应被列为非特定物质,以及可卡因能否提高比赛成绩一直以来存在争议,这些争议对反兴奋剂实践影响颇深。违规背景的多样性使得运动员说明禁用物质来源的难度较大,而不同裁决机构对可卡因争议所持的不同观点易加剧处罚结果的差异化。2021年实施版《世界反兴奋剂条例》对于可卡因等社会毒品的规定的变革使得体育仲裁裁决的指引作用能够得到进一步发挥,同时也避免严格责任原则的严厉性进一步加剧。当然,在未来的反兴奋剂进程中,在不触动政府层面药物管制原则的前提下,变革禁用清单,将可卡因纳入特定物质的范畴,既可缓和有关可卡因的争议,又可增强裁决处理的一致性与稳定性,为运动员规范自身行为提供合理预期。
