Technological Change and Frontline Care Delivery Work: Toward the Quadruple Aim.

The COVID-19 pandemic stressed the health care sector's longstanding pain points, including the poor quality of frontline work and the staffing challenges that result from it. This has renewed interest in technology-centered approaches to achieving not only the "Triple Aim" of reducing costs while raising access and quality but also the "Quadruple Aim" of doing so without further squeezing wages and abrading job quality for frontline workers. How can we leverage technology toward the achievement of the Quadruple Aim? I view this as a "grand challenge" for health care managers and policymakers. Those looking for guidance will find that most analyses of the workforce impact of technological change consider broad classes of technology such as computers or robots outside of any particular industry context. Further, they typically predict changes in work or labor market outcomes will come about at some ill-defined point in the medium to long run. This decontextualization and detemporization proves markedly problematic in the health care sector: the nonmarket, institutional factors driving technology adoption and implementation loom especially large in frontline care delivery, and managers and policymakers understandably must consider a well-defined, near-term, i.e., 5-10-year, time horizon. This study is predicated on interviews with hospital and home health agency administrators, union representatives, health care information technology (IT) experts and consultants, and technology developers. I detail the near-term drivers and anticipated workforce impact of technological changes in frontline care delivery. With my emergent prescriptions for managers and policymakers, I hope to guide sectoral actors in using technology to address the "grand challenge" inherent to achieving the Quadruple Aim.

Experimental Investigation on the Performance of Photovoltaic Panel with and Without Phase Change Material Heat Sink

Abstract The future of solar energy conversion into electricity is one of the recognized classes of technology seeing that abundance of a free and clean source of energy in almost every part of continents. The effect of exceeding in temperature on Photovoltaic (PV) cells remains one of the major disadvantages of this technology. In order to improve the power utilization of the PV panel, it is necessary to maintain cell temperature as low as possible. The purpose of this paper is to present an experimental study of a photovoltaic panel with and without Phase Change Material (PCM) heat sink and investigate the possibility of performance improvement in terms of power produced and the energy conversion efficiency. The experimental setup consists of two PV solar panel, one coated with a special type of conductive phase change material and the other being a conventional panel without the PCM. Both the panels are connected independently to a data logger from which record of the temperature for each solar panel has been obtained. Further, this recorded temperature of both panels is analyzed and compared with each other. The performed experimental result shows that output cell power is increased due use of the PCM over the traditional conventionally available panel without PCM. This can significantly increase the system efficiency of the panel and shows that method a, with cooling system improve the performance of a photovoltaic panel.

Patterns of Innovation in Green ICT: A Patent-Based Analysis

In times of economic and ecological crises, green ICTs have the potential to stir greener economic growth and to help decouple this growth from ecological damages. It is therefore paramount to shed light on innovation dynamics in this emerging sector. To do so, this paper investigates the characteristics of the patterns of innovation in the green ICT sector by using granted EPO patents data from 1986 to 2006 related to the green inventory technological classes and ICT technological classes. By way of a network analysis, it identifies existing green ICTs domains and investigates the most innovative ones, examining the degree of concentration of innovative activities as well as the entry of new innovators in the domain and the variety of innovators (e.g. small vs. large firms; private firms vs. universities and public research centres), together with the sources of knowledge. Results indicate first that monitoring and measuring technologies are dominant in this sub-sector, but also that the fields related to liquid crystal displays and solar cells are the fastest growing. Second, the analysis highlights the existence of three different clusters – green fields, emerging fields and established fields – that are defined by different structures of innovative activities and by different technological opportunities.

Monitoring the Coastal Environment; Part I: Waves and Currents

Measurement waves and currents in the high-energy, hazardous nearshore zone is one of the more challenging endeavors of coastal engineering and research. A measurement program must be thoroughly planned before any gauges are deployed to insure that useful data are collected: (1) Determine what data units and analyzed products are needed to answer the critical engineering or scientific questions at the site. (2) Determine how long the gauges must be at the site i.e., several years or just during the winter season? (3) Consider placing gauges in locations that are compatible with previous measurement programs. (4) Evaluate environmental constraints such as ice or trawler activity. (5) Be sure that enough funding is allocated for the analysis of the data. Two general types of wave gauges are commonly used: non-directional and directional. Despite the greater cost and complexity, the latter is preferred for most projects because of the need to evaluate wave refraction at the coast. Meticulous quality control is critical for all wave measurement programs. Three general classes of current measuring technology are used in coastal projects: (1) Radar and Lagrangian methods (dye and drogues); (2) Point source (Eulerian) technology such as ducted impeller instruments; (3) Acoustic Doppler Current Profilers. As gauges are improved, massive amounts of data are being collected at field projects. Clear, simple, and concise display of wave and current data are important aspects of the analysis procedure.
