This article systematically reviews the literature on online task crowdwork to investigate the complex relationship between technology and work design on crowdwork platforms. We highlight the diverse interpretations and uses of technology, specifically platform features and algorithms, in relation to work design. Our review reveals that platform features serve as antecedents to work design characteristics, while algorithms are so intertwined with job execution that a new work characteristic is needed to model this interplay. We introduce this new work characteristic as algorithmic embeddedness and show that it varies in degree. When high, algorithmic embeddedness can be perceived as either an …

Is Knowledge Management (Finally) Extractive? – Fuller’S Argument Revisited In The Age Of Ai, Norman Mooradian

Faculty Research, Scholarly, and Creative Activity

Aim/Purpose The rise of modern artificial intelligence (AI), in particular, machine learning (ML), has provided new opportunities and directions for knowledge management (KM). A central question for the future of KM is whether it will be dominated by an automation strategy that replaces knowledge work or whether it will support a knowledge-enablement strategy that enhances knowledge work and uplifts knowledge workers. This paper addresses this question by re-examining and updating a critical argument against KM by the sociologist of science Steve Fuller (2002), who held that KM was extractive and exploitative from its origins. Background This paper re-examines Fuller’s argument …

New 2d Penta-Sipn: A Wide And Indirect Bandgap Semiconductor, I. A. Qattan, Shambhu Bhandari Sharma, K. C. Santosh, Sufian Abedrabbo

Faculty Research, Scholarly, and Creative Activity

In recent years, two-dimensional (2D) pentagonal ternary monolayers have attracted much attention and emerged as a new class of materials because of their new feature and extensive applicability. Using first-principles density functional theory (DFT) calculations, we predict a new 2D pentagonal-SiPN or p-SiPN monolayer material. The new monolayer has shown to be structurally, thermodynamically, and dynamically stable. Our findings imply that p-SiPN is a wide and indirect bandgap semiconductor, with a highly tunable bandgap with applied equ-biaxial strain. This makes p-SiPN a promising candidate for futuristic optoelectronics and nanomechanics device applications.

Opening The Black Box: Carbon-Footprint Calculators, Meat Consumption, And The “Wicked Problem” Of Metric Governance, E. Melanie Dupuis, Dustin Mulvaney

Faculty Research, Scholarly, and Creative Activity

Carbon-footprint calculators are widely used as communication and education tools, designed to make people aware of the ways their personal actions contribute to greenhouse-gas emissions. However, they have come under criticism for emphasizing individual behavior versus structural change. We extend this critique to argue that carbon-footprint calculators are a form of “metric governance” that not only disciplines users but also constrains their abilities to engage with the complexities of climate change and social action. We focus on a particularly wicked problem of carbon-metric governance: livestock greenhouse-gas emissions. We show that carbon-footprint calculators black box and fix the complex politics and …

Robust Metabolic Syndrome Risk Score Based On Triangular Areal Similarity, Hyunseok Shin, Simon Shim, Sejong Oh

Faculty Research, Scholarly, and Creative Activity

One of the limitations of currently-used metabolic syndrome (MetS) risk calculations is that they often depend on sample characteristics. To address this, we introduced a novel sample-independent risk quantification method called ‘triangular areal similarity’ (TAS) that employs three-axis radar charts constructed from five MetS factors in order to assess the similarity between standard diagnostic thresholds and individual patient measurements. The method was evaluated using large datasets of Korean (n = 72, 332) and American (n = 11, 286) demographics further segmented by sex, age, and race. The risk score exhibited a strong positive correlation with the number of abnormal factors …
