An effect of the COVID-19 pandemic, it is sometimes suggested, will be to reverse the secular trend toward questioning the value of scientific research and expertise. We analyze this hypothesis by examining how exposure to previous epidemics affected the confidence of individuals in science and scientists. Consistent with theory and evidence that attitudes are durably formed when individuals are in their impressionable years between the ages of 18 and 25, we focus on people who were exposed to epidemics in their country of residence at this stage of the life course. Combining data from a 2018 Wellcome Trust survey of more than 70,000 individuals in 160 countries with data on global epidemics since 1970, we show that such exposure has no impact on views of science as an endeavor or on opinions of whether the study of disease is properly an aspect of science, but that it significantly reduces confidence in scientists and the benefits of their work. These findings are robust to a variety of controls, empirical methods and sensitivity checks. We suggest some implications for how scientific findings are communicated and for how scientists seeking to inform and influence public opinion should position themselves in the public sphere.
Summary form only given. It has become apparent, that silicon technology can provide many of the requirements for nano-photonic integration, including many of the common opto-electronic components. Intel and Luxtera have both recently announced 10 Gb/sec optical modulators, integrated into silicon. Actually, all the other customarily required opto-electronic components are available now in silicon, as well. Continuous wave optical power can be provided from off-chip, just as dc power is currently provided from off-chip. The first commercial applications are emerging, are optical 10 Gb/s Ethernet, and Infiniband, a standard for communicating among multi-processors in an array, and in general, optical substitutes for electrical cables.
The orbital motion of electrons in a three-dimensional solid can generate a pseudoscalar magnetoelectric coupling theta, a fact we derive for the single-particle case using a recent theory of polarization in weakly inhomogeneous materials. This polarizability theta is the same parameter that appears in the "axion electrodynamics" Lagrangian DeltaL_{EM}=(thetae;{2}/2pih)E.B, which is known to describe the unusual magnetoelectric properties of the three-dimensional topological insulator (theta=pi). We compute theta for a simple model that accesses the topological insulator and discuss its connection to the surface Hall conductivity. The orbital magnetoelectric polarizability can be generalized to the many-particle wave function and defines the 3D topological insulator, like the integer quantum Hall effect, in terms of a topological ground-state response function.
Ethnoracial violence is a dynamic and multilayered phenomenon whose definition is at stake not only in academe but also in reality itself. It comes in two varieties, expressive and instrumental, when it serves to buttress the other four elementary forms of racial domination, namely, categorization, discrimination, segregation, and seclusion. I point out that the phenomenon is relatively rare and burdened with heavy moral baggage. I introduce distinctions based on directionality (vertical, horizontal), scale of the actors involved (individual, group, or state), degree of spectacularization, and type of ethnic classification system (categorical, gradational). The imperial domain offers an especially fruitful terrain for the comparative investigation and theoretical elaboration of the dynamics of racialization, violence, and the state. Students of human brutality in history should join hands with comparative scholars of race to throw new light on their explosive intersection.
The field of dry deposition has had periods of ups and downs in activity and research.Unfortunately algorithms in important models have been fossilized to consider the Wesely model of 1989.While that was a very good and appropriate algorithm 30 years ago, we know more about land surface fluxes, how to model stomatal conductance and have been datasets and parameterization information in 2020.So, I was excited to see C1
Abstract Introduction Organizations and systems that deliver health care may better adapt to rapid change in their environments by acting as learning organizations and learning health systems (LHSs). Despite widespread recognition that multilevel forces shape capacity for learning within care delivery organizations, there is no agreed‐on, comprehensive, multilevel framework to inform LHS research and practice. Methods We develop such a framework, which can enhance both research on LHSs and practical steps toward their development. We draw on existing frameworks and research within organization and implementation science and synthesize contributions from three influential frameworks: the Consolidated Framework for Implementation Research, the social‐ecological framework, and the organizational change framework. These frameworks come, respectively, from the fields of implementation science, public health, and organization science. Results Our proposed integrative framework includes both intraorganizational levels (individual, team, mid‐management, organization) and the operating and general environments in which delivery organizations operate. We stress the importance of examining interactions among influential factors both within and across system levels and focus on the effects of leadership, incentives, and culture. Additionally, we indicate that organizational learning depends substantially on internal and cross‐level alignment of these factors. We illustrate the contribution of our multilevel perspective by applying it to the analysis of three diverse implementation initiatives that aimed at specific care improvements and enduring system learning. Conclusions The framework and perspective developed here can help investigators and practitioners broadly scan and then investigate forces influencing improvement and learning and may point to otherwise unnoticed interactions among influential factors. The framework can also be used as a planning tool by managers and practitioners.
Drawing on archival materials and personal testimonies, I reconstruct the conditions under which Bourdieu came to receive the Gold Medal of the National Center for Scientific Research, France’s highest science prize, in 1993 as a signal case study of the existential predicament and institutional trappings of scholarly consecration. Bourdieu’s award speech and the ceremony at which he read it present a triple interest for the history and sociology of sociology. They illustrate how a shaping figure in the discipline personally experienced, reflexively viewed, and practically navigated the nexus of science, authority, and power. They mark 1993 as a pivot-year in Bourdieu’s intellectual evolution, leading to a new agenda foregrounding the state as paramount symbolic power, the alchemy of group formation, and the unfinished promise of democratic politics; and they help explain why he ventured more forthrightly into civic debate in the 1990s. Bourdieu’s ambivalent acceptance of the prize also illustrates his co...
