Editorial for the Special Issue on High-End Measuring Instruments

In recent years, two major challenges have arisen in the field of measurement and instrument technology. One is the redefinition of the seven basic units in the international system of units(Système International d’Unités or SI). The SI is now based on fundamental physical constants, with full implementation having occurred in 2019.

Technology Usage among Elderly with Self-Reported Hearing Disability: Results from InveCe.Ab

Background: Awareness of hearing disability in the elderly has adverse cognitive and functional consequences over time, in a longitudinal population-based study. Aim: To analyze the hypothesis that over time old people aware of hearing disability make less use of technology and lose more instrumental activities of daily living than peers with other self-reported hearing conditions. Methods: We analyzed 1171 healthy participants in the longitudinal population-based InveCe.Ab study. The consistency between self-reported hearing loss with clinician-evaluated hearing status (Whispered Voice Test;WVT), was categorized by consistency as: unaware of hearing loss (UHL), aware of hearing loss (AHL), only subjective hearing loss (OSHL), without hearing loss (noHL). Results: At baseline (2010), hearing loss was found in 159 [13.6% (95% CI: 11.7 - 15.7)] of the participants [28 = 17.6% (95% CI: 12.0 - 24.4) AHL;131 = 82.4% (95% CI: 75.6 - 88) UHL], while 23 [2.3% (95% CI: 1.4 - 3.4)] of the subjects with normal WVT had OSHL. Mobile phone usage was significantly associated with different consistency categories (p i.e. executive, memory and visuo-spatial) were independently associated with maintaining mobile phone usage and instrumental activities of daily living. Conclusion: Self-reported hearing disability is linked to subsequent loss of mobile phone usage and functional dependency. As cognitive performances independently influence technology usage and functional impairment, targeted preventive interventions should address functional impact of perceived hearing loss, but also encourage social participation and improve mobile phone usage. Trial registration: ClinicalTrials.gov, NCT01345110;registered on April 29, 2011.

我们究竟需要什么样的技术观

技术工具论是一种社会大众广为接受的技术观,也是当前教育中的主流技术观。工具论是主客二元认识论的产物,它强调技术功能,把技术看作一种价值中立的工具,但忽视了人和教育情境的因素。技术工具论的膨胀会消解教育活动的复杂性,引发教育活动的程序化,导致教育技术应用的低效。哲学研究范式的实践转向产生了新的技术观,实践理论阐述了人的实践具有日常性、关系性、过程性和微观性的特征,并能揭示教育技术“实际上是怎么样的”。教育技术实践观有助于我们展示“人—技术—教育”的教育技术关系,以及情境化、动态性和创造性的教育技术实践过程,从而能打开教育技术实践的黑箱。教育技术实践观能助力实现教育数字化转型逻辑转变,关注微观层面的教育技术活动,打通教育数字化转型的“最后一公里”,从而赋能教育和人的全面发展,有助于探索中国式教育数字化转型之路。

结构性货币政策工具对科技创新型企业融资的影响

近年来,货币政策工具在发挥总量调节功能的同时,也有力地支持了经济结构调整和转型升级。2013年起,为加强对“三农”、小微等重点领域及薄弱环节的金融信贷支持,中国人民银行创设了常备借贷便利、抵押补充贷款、定向降准等结构性货币政策工具,向实体经济精准释放流动性,以期达到优化调节经济结构的政策目的。本文从结构性货币政策工具与科技创新型企业融资间的关系出发,尝试对结构性货币政策工具支持科技创新型企业的效果进行评价,认为结构性货币政策工具能够促进科技创新型企业融资,且在不良贷款率较低、地区GDP增长率较高的金融机构中具有更强的政策传导效应,更能促进科技创新型企业贷款增量扩面。在此基础上,提出应从加强结构性货币政策工具支持力度,完善结构性货币政策工具设计,加强货币、财政、产业政策协调配合三个方面改善结构性货币政策工具传导效能。
