In response to the bleak prospects of today’s financial markets, a wave of financial and technological innovations emerges, bringing about potential benefits but also new challenges. For instance, tokenized securities are a new kind of blockchain-based asset enabling price stability, programmability, pseudonymity, and transaction efficiency, while also introducing new regulatory challenges and uncertainties. Conversely, index funds are an established investment device enabling broad diversification in a cost-effective, tax-efficient, and transparent way, while potentially also contributing to concentration of market power, intermediation cost, access barriers for underbanked or impoverished investors, increased market volatility, and human behavioral challenges. This paper conceptually develops Tokenized Index Funds as a hybrid approach that combines the benefits of tokenized securities and index funds while alleviating some of their drawbacks. Based thereupon, a corresponding multidisciplinary research framework is presented, with sample research questions along the activities of design and features, business and economics, management and organization, and law and regulation. 相似文献

获得感是教师培训所追求的目标和评判标准,信息技术应用能力是提高教师教学胜任力和获得感的重要途径之一。文章从教师获得感出发,介绍了教师信息技术应用能力培训获得感的内涵,提出了一种高获得感的教师信息技术应用能力培训新方式——极简培训。介绍了极简培训的内涵和开展教师极简培训的三种策略:“自定航向”的培训导向、按类按需分层的培训内容、基于“快闪教学法”的培训方式。对未来开展教师信息技术应用能力极简培训提出了两个建议:建设极简培训在线课程体系,学习者以“拼团学习”随机组合的方式构建微学习共同体,开展在线协作学习;建设极简培训评价体系,基于区块链技术生成学习证明,实现学习证明的分布存储、防伪溯源和不可更改。基于三种实施策略和两个未来发展建议的极简培训,为新时代教师信息技术应用能力培训提供了一种新的思路和方法。 相似文献

在互联网时代,基于在线学习方式的开放教育日益被教育机构及学习者采纳和接受。开放教育在为学习者带来时空便利的同时,其在数据层面上引发的信任危机也亟待解决。开放教育可划分为教学资源开放共享、大规模教学交互、跨平台开放等三个阶段,数据在其发展过程中起到了原始驱动力的作用,并在其质量提升中扮演着重要角色。构建贯穿开放教育数据产生、流通和传播全过程的信任机制十分重要,而具有去中心化、去信任化、防篡改、可追溯等特性的区块链技术可用于构建开放教育参与者间的信任关系,进而从以下几个方面重构互联网时代的开放教育:一是实现优质教育资源在分享和传播中的确权;二是保障开放教育环境下的学习成果互认;三是保证开放教育情境中的数据可信,并准确实现教育的“以人推己”。虽然区块链技术在开放教育中具有广阔的应用前景,但针对教育的现实情境,其仍存在以下技术问题有待解决:一是数据存储受到单节点存储容量的限制;二是共识协议所支持的节点数目偏少;三是缺乏面向教育规章制度的高效合约建模及执行方法;四是数据在多方间的公开使得对用户隐私保护难以实现;五是轻客户端使得验证查询功能受限。 相似文献

This article departs from the post 2008 financial crisis context, from its intersection with technological developments, and from the socio-technical arrangements configured by this conjuncture. It explores plans and actions – of mainstream financial institutions, and of a community seeking for alternatives to centralised economy and governance – for the use of digital platforms supported by blockchain infrastructure. In particular, it explores how such plans and actions relate to conceptions of public and peer trust and how they appear to produce, or reinforce, reputational imaginaries and quantification practices within added value philosophies. By illuminating a tension between the two identified case examples, I seek to render alternative communities’ and financial institutions’ conceptions, imaginaries and practices (more) visible and to analyse their organisational marketing strategies – where there is a pragmatic and discursive operationalisation of technology as well as of trust as means to gain more self-sovereignty in action, while navigating markets and regulated actual world contexts. 相似文献

This conceptual paper explores the impact of blockchain technology on public sector processes through the lens of information security. It includes an overview of the evolution of e-government, a synopsis of existing applications of blockchain technology, and innovative blockchain developments. We utilize the Confidentiality-Integrity-Accessibility (CIA) triad to guide our discussion of the security, governance, and regulatory implications of this technology. Leveraging the CIA triad model, we provide context for public managers who may consider blockchain technologies, and we highlight certain advantages arising from the “non-reputability” of distributed ledgers.In particular, we highlight the advantages of blockchain technologies with regards to non-reputability to help public managers understand how to best leverage blockchain technology to transform operations. 相似文献
