Using Nesting to Push the Limits of Transactional Data Structure Libraries

Transactional data structure libraries (TDSL) combine the ease-of-programming of transactions with the high performance and scalability of custom-tailored concurrent data structures. They can be very efficient thanks to their ability to exploit data structure semantics in order to reduce overhead, aborts, and wasted work compared to general-purpose software transactional memory. However, TDSLs were not previously used for complex use-cases involving long transactions and a variety of data structures. In this paper, we boost the performance and usability of a TDSL, towards allowing it to support complex applications. A key idea is nesting. Nested transactions create checkpoints within a longer transaction, so as to limit the scope of abort, without changing the semantics of the original transaction. We build a Java TDSL with built-in support for nested transactions over a number of data structures. We conduct a case study of a complex network intrusion detection system that invests a significant amount of work to process each packet. Our study shows that our library outperforms publicly available STMs twofold without nesting, and by up to 16x when nesting is used

The ‘fintech revolution’ is here! The disruptive impact of fintech on retail financial practices

Fintech is celebrated for its disruptive and democratizing qualities that dis/reintermediates the finance value chain. Claims of a ‘fintech revolution’ assume that fintech is ‘disruptive’ because of its innovative capabilities, but the extent to which these disruptive forces have reconfigured consumer financial knowledge and practices is not well understood. Using a questionnaire to survey retail consumers in Singapore on their use of fintech in performing different financial tasks, this article critically examines these claims of disruption and democratization by grounding them in the financial behaviors of consumers as informed by a financial ecologies approach. The results show a limited impact of fintech in shaping consumer financial behaviors. Respondents use fintech mainly for basic transactional purposes like making mobile payments and account management, but not so much for more complex matters like savings, investing and credit. The findings also reveal a ‘stickiness’ in financial behaviors that emphasizes the high touch points of human interaction. This study illustrates fintech’s variegated material outcomes by highlighting the unevenness in consumption of digital financial services and the enduring importance of human relationality in financial decision making

New Tech v. New Deal: Fintech as a Systemic Phenomenon

Fintech is the hottest topic in finance today. Recent advances in cryptography, data analytics, and machine learning are visibly disrupting traditional methods of delivering financial services and conducting financial transactions. Less visibly, fintech is also changing the way we think about finance: it is gradually recasting our collective understanding of the financial system in normatively neutral terms of applied information science. By making financial transactions easier, faster, and cheaper, fintech seems to promise a micro-level win-win solution to the financial system\u27s many ills. This Article challenges such narratives and presents an alternative account of fintech as a systemic, macro-level phenomenon. Grounding the analysis of evolving fintech trends in a broader institutional context, the Article exposes the normative and political significance of fintech as the catalyst for a potentially decisive shift in the underlying public-private balance of powers, competencies, and roles in the financial system. In developing this argument, the Article makes three principal scholarly contributions. First, it introduces the concept of the New Deal settlement in finance: a fundamental political arrangement, in force for nearly a century, pursuant to which profit-seeking private actors retain control over allocating capital and generating financial risks, while the sovereign public bears responsibility for maintaining systemic financial stability. Second, the Article advances a novel conceptual framework for understanding the deep-seated dynamics that have eroded the New Deal settlement in recent decades. It offers a taxonomy of core mechanisms that both (a) enable private actors to continuously synthesize tradable financial assets and scale up trading activities, and (b) undermine the public’s ability to manage the resulting system-wide risks. Finally, the Article shows how and why specific fintech applications – cryptocurrencies, distributed ledger technologies, digital crowdfunding, and robo-advising – are poised to amplify the effect of these destabilizing mechanisms, and thus potentially exacerbate the tensions and imbalances in today’s financial markets and the broader economy. It is this potential that renders fintech a public policy challenge of the highest order

Low-Coders, No-Coders, and Citizen Developers in Demand: Examining Knowledge, Skills, and Abilities Through a Job Market Analysis

The emergence of low-code/no-code (LCNC) platform technologies and the resulting increase in citizen development programs are facilitating the democratization of the design, development, and deployment of digital solutions. Citizen developers, non-technical employees who leverage LCNC platforms, are at the heart of this trend. While many firms perceive LCNC and citizen development as a crucial component of their digital transformation strategy, little is known about the evolving roles in this field or the necessary knowledge, skills, and abilities (KSA). To address this knowledge gap, we processed 113,106 job postings published on Indeed.com. Our topic modeling methodology identified 34 KSA topics and classified them into the three domains platform, business, and technology. We contribute to research by empirically demonstrating which competencies are required to successfully work in the LCNC field. Our findings can guide individual professionals and organizations alike
