A New Measure of Digital Economic Activity and its Impact on Local Opportunity

Online businesses and platform work can create the impression that the digital economy is ephemeral and placeless. But the digital economy is experienced locally, and its effects are spatial. Measuring them requires better community-level data on economic activities online. While new government data measures broadband subscriptions down to neighborhoods, existing public data do not measure how broadband is used in local communities, and whether this digital activity affects economic outcomes. We analyze new monthly data on over 20 million domain name hosts/websites in the United States from November 2018 to November 2020 drawing on customer data. Surveys show that 3 out of 4 of these domains are commercial, including microbusinesses as well as websites for both online and brick-and-mortar establishments. How is the density of domain name hosts in a community (the number in a zip code or county divided by the population) related to local economic opportunity, controlling for other known factors? Using statistical matching and time series data, results show the density of domain name hosts positively predicts community economic prosperity, recovery from the 2008 recession, and change in median income. Interactions between the density of these hosts and broadband subscriptions also predict lower monthly unemployment rates over time, including after the March 2020 pandemic. Commercial data can improve our understanding of broadband\u27s impacts, including its potential for inclusive growth in diverse communities

Tension on JAM-A activates RhoA via GEF-H1 and p115 RhoGEF

Junctional adhesion molecule A (JAM-A) is a broadly expressed adhesion molecule that regulates cell–cell contacts and facilitates leukocyte transendothelial migration. The latter occurs through interactions with the integrin LFA-1. Although we understand much about JAM-A, little is known regarding the protein’s role in mechanotransduction or as a modulator of RhoA signaling. We found that tension imposed on JAM-A activates RhoA, which leads to increased cell stiffness. Activation of RhoA in this system depends on PI3K-mediated activation of GEF-H1 and p115 RhoGEF. These two GEFs are further regulated by FAK/ERK and Src family kinases, respectively. Finally, we show that phosphorylation of JAM-A at Ser-284 is required for RhoA activation in response to tension. These data demonstrate a direct role of JAM-A in mechanosignaling and control of RhoA and implicate Src family kinases in the regulation of p115 RhoGEF

Long-Term Demonstration of Hydrogen Production from Coal at Elevated Temperatures Year 6 - Activity 1.12 - Development of a National Center for Hydrogen Technology

The Energy & Environmental Research Center (EERC) has continued the work of the National Center for Hydrogen Technology® (NCHT®) Program Year 6 Task 1.12 project to expose hydrogen separation membranes to coal-derived syngas. In this follow-on project, the EERC has exposed two membranes to coal-derived syngas produced in the pilot-scale transport reactor development unit (TRDU). Western Research Institute (WRI), with funding from the State of Wyoming Clean Coal Technology Program and the North Dakota Industrial Commission, contracted with the EERC to conduct testing of WRI’s coal-upgrading/gasification technology for subbituminous and lignite coals in the EERC’s TRDU. This gasifier fires nominally 200–500 lb/hour of fuel and is the pilot-scale version of the full-scale gasifier currently being constructed in Kemper County, Mississippi. A slipstream of the syngas was used to demonstrate warm-gas cleanup and hydrogen separation using membrane technology. Two membranes were exposed to coal-derived syngas, and the impact of coal-derived impurities was evaluated. This report summarizes the performance of WRI’s patent-pending coalupgrading/ gasification technology in the EERC’s TRDU and presents the results of the warm-gas cleanup and hydrogen separation tests. Overall, the WRI coal-upgrading/gasification technology was shown to produce a syngas significantly lower in CO2 content and significantly higher in CO content than syngas produced from the raw fuels. Warm-gas cleanup technologies were shown to be capable of reducing sulfur in the syngas to 1 ppm. Each of the membranes tested was able to produce at least 2 lb/day of hydrogen from coal-derived syngas

Theorization as institutional work: The dynamics of roles and practices

This study unpacks the construct of theorization – the process by which organizational ideas become delocalized and abstracted into theoretical models to support their diffusion across time and space. We adopt an institutional work lens to analyze the key components of theorization in contexts where institutional work is in transition from creating institutions to maintaining them. We build on a longitudinal inductive study of theorization by the Fair Labor Association (FLA), a private regulatory initiative which created and then enforced a code of conduct for working conditions in apparel factories. Our study reveals that when institutional work shifts from creating to maintaining an institutional arrangement of corporate social responsibility, there is a key change in how the FLA theorizes roles and practices related to this arrangement. We observe that theorization on key practices largely remain intact, whereas the roles of different actors are theorized in a dramatically different manner. Our findings contribute to a better understanding of the work involved in the aftermath of radical change by demonstrating the relative plasticity of roles over the rigidity of practices

The labor market regimes of Denmark and Norway – one Nordic model?

The literature on the Danish and Norwegian labor market systems emphasizes the commonalities of the two systems. We challenge this perception by investigating how employers in multinational companies in Denmark and Norway communicate with employees on staffing changes. We argue that the development of ‘flexicurity’ in Denmark grants Danish employers considerably greater latitude in engaging in staffing changes than its Nordic counterpart, Norway. Institutional theory leads us to suppose that large firms located in the Danish setting will be less likely to engage in employer–employee communication on staffing plans than their Norwegian counterparts. In addition, we argue that in the Danish context indigenous firms will have a better insight into the normative and cognitive aspects to flexicurity than foreign-owned firms, meaning that they are more likely to engage in institutional entrepreneurialism than their foreign owned counterparts. We supplement institutional theory with an actor perspective in order to take into account the role of labor unions. Our analysis is based on a survey of 203 firms in Norway and Denmark which are either indigenous multinational companies or the subsidiaries of foreign multinational companies. The differences we observe cause us to conclude that the notion of a common Nordic model is problematic

N-glycosylation controls the function of junctional adhesion molecule-A

Junctional adhesion molecule-A (JAM-A) is an adherens and tight junction protein expressed by endothelial and epithelial cells. JAM-A serves many roles and contributes to barrier function and cell migration and motility, and it also acts as a ligand for the leukocyte receptor LFA-1. JAM-A is reported to contain N-glycans, but the extent of this modification and its contribution to the protein’s functions are unknown. We show that human JAM-A contains a single N-glycan at N185 and that this residue is conserved across multiple mammalian species. A glycomutant lacking all N-glycans, N185Q, is able to reach the cell surface but exhibits decreased protein half-life compared with the wild- type protein. N-glycosylation of JAM-A is required for the protein’s ability to reinforce barrier function and contributes to Rap1 activity. We further show that glycosylation of N185 is required for JAM-A–mediated reduction of cell migration. Finally, we show that N-glycosylation of JAM-A regulates leukocyte adhesion and LFA-1 binding. These findings identify N-glycosylation as critical for JAM-A’s many functions

A Mechanism-Based Explanation of the Institutionalization of Semantic Technologies in the Financial Industry

Part 3: Creating Value through ApplicationsInternational audienceThis paper explains how the financial industry is solving its data, risk management, and associated vocabulary problems using semantic technologies. The paper is the first to examine this phenomenon and to identify the social and institutional mechanisms being applied to socially construct a standard common vocabulary using ontology-based models. This standardized ontology-based common vocabulary will underpin the design of next generation of semantically-enabled information systems (IS) for the financial industry. The mechanisms that are helping institutionalize this common vocabulary are identified using a longitudinal case study, whose embedded units of analysis focus on central agents of change—the Enterprise Data Management Council and the Object Management Group. All this has important implications for society, as it is intended that semantically-enabled IS will, for example, provide stakeholders, such as regulators, with better transparency over systemic risks to national and international financial systems, thereby mitigating or avoiding future financial crises

Evaluation Research and Institutional Pressures: Challenges in Public-Nonprofit Contracting

This article examines the connection between program evaluation research and decision-making by public managers. Drawing on neo-institutional theory, a framework is presented for diagnosing the pressures and conditions that lead alternatively toward or away the rational use of evaluation research. Three cases of public-nonprofit contracting for the delivery of major programs are presented to clarify the way coercive, mimetic, and normative pressures interfere with a sound connection being made between research and implementation. The article concludes by considering how public managers can respond to the isomorphic pressures in their environment that make it hard to act on data relating to program performance.This publication is Hauser Center Working Paper No. 23. The Hauser Center Working Paper Series was launched during the summer of 2000. The Series enables the Hauser Center to share with a broad audience important works-in-progress written by Hauser Center scholars and researchers

How do enterprises respond to a managerial accounting performance measure mandated by the state?

We study the application of Economic Value Added (EVA®) by Chinese state-owned enterprises (SOEs) following a regulatory requirement to deploy the measure. Our theoretical framing engages conceptual elements of institutional work and public accountability research to consider why key actors vary in their responses to the mandated application of EVA®. Our data derives from thirty interviews with managers in three SOEs and their oversight body (the State-owned Assets Supervision and Administration Commission of the State Council). We identify two relevant dimensions associated with managers: 'accounting centricity' and 'institutional potential' and report that they drive the authenticity of actors' responses in the absence of enforcement of the mandated measure. When accounting centricity and institutional potential align to the dictates of the higher implementing body, accountability remains high notwithstanding the absence of enforcement. When these two factors do not align, accountability fails even when politicization is high and formal accountability claims are high. Where the two factors are partially present, the accountability response is mixed. Our study contributes to a refinement of the perspective advanced by prior investigations of institutionally sanctioned roll outs of accounting systems highlighting in particular, the role of human agency in explaining actor responses
