<p>The analysis presented in this manuscript helps bridge an important fundamental discrepancy between the existing theoretical and experimental knowledge regarding the performance of Ag catalysts for CO<sub>2</sub> electrochemical reduction (CO<sub>2</sub>ER). The results demonstrate how the intermediate species *OCHO is formed readily en-route the HCOO<sup>– </sup>pathway and plays a decisive role in determining selectivity of a predominantly CO producing catalyst such as Ag. Our theoretical and experimental approach develops a better understanding of the nature of competition as well as the complex interactions between the reaction intermediates leading to CO, HCOO<sup>–</sup> and H<sub>2</sub> during CO<sub>2</sub>ER.</p><p><br></p><p>Details of computational and experimental methods are present in the Supporting Information provided. </p><p><br></p><p><br></p>

This chapter is an analysis of the project appraisal procedures in place at American Research and Development Corporation (ARD) between 1946 and 1973, under the management of Georges F. Doriot. It shows the importance of knowledge technologies and administrative procedures in the way the venture capital company dealt with uncertain futures. The origins of these knowledge practices are traced back to Georges F. Doriot’s own views on business and more generally to the pragmatist movement in business administration of which he was a member. The conduct of project appraisal at ARD is then observed directly, and this reveals its reliance on a rich set of knowledge and diagnostic techniques as well as administrative procedures. These observations allow for a specification of the nature and role of imagination in the entrepreneurship and venture capital practices examined here—in particular, its close relationship with organized knowledge.

AbstractSeeing the entwinement of social and epistemic challenges through COVID, we discuss the perils of simplistic appeals to ‘follow the science’. A hardened scientism risks excarbating social conflict and fueling conspiracy beliefs. Instead, we see an opportunity to devise more inclusive medical knowledge practices through endorsing experiential knowledge alongside traditional evidence types.

AbstractThis essay takes as its assumptive backdrop the “Red/White/Black demographic triad” in the sense of Stam and Shohat that resulted from the European colonial conquest and settlement of, and the transatlantic enslavement of Africans in, the Americas. It homes in on the ambivalent functions and effects of different evocations of Indigeneity in early abolitionist discourse, considering this very discourse as a specific strand of settler colonial knowledge production during the era of the Enlightenment. While Euro-American abolitionists around 1800 centrally and critically focused on relations between the positions marked by “Black” and “White,” they also made recourse to the position of “Red.” Paradigmatic readings highlight that abolitionists mobilized Red as a trope in contradictory ways according to their argumentative needs, substantiating the hegemonic character of White self-referential knowledge practices in the early US republic and abetting the justification of settler colonialism.

Abstract Social philosophers often invoke the concept of false consciousness in their analyses, referring to a set of evidence-resistant, ignorant attitudes held by otherwise sound epistemic agents, systematically occurring in virtue of, and motivating them to perpetuate, structural oppression. But there is a worry that appealing to the notion in questions of responsibility for the harm suffered by members of oppressed groups is victim-blaming. Individuals under false consciousness allegedly systematically fail the relevant rationality and epistemic conditions due to structural distortions of reasoning or knowledge practices, undermining their status as responsible moral agents. But attending to the constitutive mechanisms and heterogeneity of false consciousness enables us to see how having it does not in itself render someone an inappropriate target of blame. I focus here on the 1889 antisuffragist manifesto “An Appeal against Female Suffrage,” arguing that its signatories, despite false consciousness, satisfy both conditions for ordinary blameworthiness. I consider three prominent signatories, observing that the irrationality characterization is unsustainable beyond group-level diagnoses, and that their capacity to respond appropriately to reasons was not compromised. Following recent work on epistemic injustice, I also argue that culpable mechanisms constituted their false consciousness, rendering them blameworthy for the Appeal.

AbstractIndigenous artists are introducing traditional knowledge practices to the contemporary art world. This article discusses the work of selected Indigenous artists and relays their contribution towards changing art discourses and understandings of Indigenous knowledge. Anishinaabe artist Norval Morrisseau led the way by introducing ancient mythos; the gifted Carl Beam enlarged his oeuvre with ancient building practices; Peter Clair connected traditional Mi'kmaq craft and colonial influence in contemporary basketry; and Edward Poitras brought to life the cultural hero Coyote. More recently, Beau Dick has surprised international art audiences with his masks; Christi Belcourt’s studies of medicinal plants take on new meaning in paintings; Bonnie Devine creates stories around canoes and baskets; Adrian Stimson performs the trickster/ruse myth in the guise of a two-spirited character; and Lisa Myers’s work with the communal sharing of food typifies a younger generation of artists re-engaging with traditional knowledge.

ArgumentWithin the Republic of Letters the art of experiment led to immense reorientation and an extensive redrawing of the enlightened map of natural knowledge. This paper will investigate the formative period of the exact sciences from the late eighteenth to the nineteenth century when the persona of the experimentalist as a scientific expert was shaped. The paper focuses on Moritz Hermann Jacobi’s experimental knowledge derived from his modeling of an electro-magnetic self-acting machine and the social and epistemological problems of its integration into traditional academic life. His struggle to achieve academic recognition and credibility for his experimental work reflects not just his individual quandary, but important structural problems of the historical development of experimental knowledge traditions and science in what has been called the “second scientific revolution.”

We report recent measurements on τ leptons obtained by the BABAR collaboration using the entire recorded sample of electron-positron collisions at and around the Υ(4S) (about 470fb-1). The events were recorded at the PEP-II asymmetric collider at the SLAC National Accelerator Laboratory. The measurements include high multiplicity τ decay branching fractions with 3 or 5 charged particles in the final state, a search for the second class current the τ decay τ → πη′ν, τ branching fractions into final states containing two KS mesons, [Formula: see text], with h = π, K, and preliminary measurements of hadronic spectra of τ decays with three hadrons (τ- → h-h+h-ντ decays, where h = π, K). The results improve the experimental knowledge of the τ lepton properties and can be used to improve the precision tests of the Standard Model.
