Employers and governments are interested in the use of serological testing to allow people to return to work before there is a vaccine for SARS-CoV-2. We articulate the preconditions needed for the implementation of antibody testing, including the role of the U.S. Food & Drug Administration.

Critics have maintained that John Rawls’s theory of justice is unrealistic and undemocratic. Andrius Gališanka’s incisive intellectual biography argues that in misunderstanding the origins and development of Rawls’s argument, previous narratives fail to explain the novelty of his philosophical approach and so misunderstand his political vision.

This essay, written in memory of Erik Olin Wright, explores the possibility of liberal socialism. Wright sought to rescue both liberalism and socialism from their demonstrated capacity for depredation. His legacy challenges reformers to proceed with the audacity of real, and realistic, utopianism together with an awareness that, unfortunately, the obverse of an appealing utopianism always beckons.

The evolutionary history of muscle development in the paired fins of teleost fish and the limbs of tetrapod vertebrates is still, to a large extent, uncertain. There has been a consensus, however, that in the vertebrate clade the ancestral mechanism of fin and limb muscle development involves the extension of epithelial tissues from the somite into the fin/limb bud. This mechanism has been documented in chondrichthyan, dipnoan, chondrostean and teleost fishes. It has also been assumed that in amniotes, in contrast, (...) individual progenitor cells of muscles migrate from the somites into the limb buds. Neyt et al.(1) now present the exciting finding that in zebrafishes this presumably derived mechanism involving individual cell migration, is present. They conclude, based on data on sharks, zebrafishes, chickens, quails and mice that the derived mechanism was present in the sarcopterygians. This conclusion, however, may be premature in the light of further data available in the literature, which show a highly mosaic distribution of this character in the vertebrate clade. Furthermore, a developmental mode exists that is intermediate between the supposed ancestral and derived modes in teleosts, reptiles and possibly amphibians.

This paper proposes an innovative approach to achieving real-time polymorphic behavior detection, and its direct application to blockchain-focused smart-contracts. We devise a method based on a non-deterministic finite state machine to perform approximate pattern-matching, using a look-ahead mechanism implemented through a concept similar to that of a sliding window, and using threshold-based similarity checking at every state in the automaton. We introduce and formalize our approach, discuss the challenges we faced and then test it in a real-world environment. The experimental (...) results obtained showed a significant speed-up of our approach, as compared to the classic similarity measures used commonly in such scenarios. (shrink)

In this major intellectual history, Ira Katznelson examines the works of Hannah Arendt, Robert Dahl, Richard Hofstadter, Harold Lasswell, Charles Lindblom, Karl Polanyi, and David Truman, detailing their engagement with the larger project of reclaiming the West's moral bearing.

Niccolo Machiavelli’s teachings have never gone out of fashion; no doubt because power remains a central aspect of modern political and corporate life. The writings of this 16th century thinker seem as relevant today as they were a half millennium ago. Given the immutable nature of human beings, this is hardly surprising. What is surprising is the regular stream of monographs published in the last third of the 20th century, and reaching a crescendo in the last decade, that argue for (...) Machiavelli’s relevance to modern management and corporate leadership. This essay will examine the structure, assumptions and conclusions of these manuals. After reviewing the manuals, this essay concludes that certain of these assumptions upon which these manuals are based are not transferable from a 16th century principality to a 21st century corporation. Not surprisingly, the teachings of these manuals concerning morality and the corporation are either inconsistent with the actual teachings of Machiavelli, or fail to acknowledge the teachings of Machiavelli most relevant to the modern corporate world.

The aim of this chapter is to identify the most representative measures of subjective and objective mental workload in driving, and to understand how the subjective and objective levels of mental workload influence the performance as a function of situation complexity and driving experience, i.e. to verify whether the increase of situation complexity and the lack of experience increase the subjective and physiological levels of mental workload and lead to driving performance impairments. This chapter will be useful to carry out (...) an experimental study and to improve the driver training. In the first part, we will broach the theoretical approach with two factors of mental workload and performance, i.e. situation complexity and driving experience. Indeed, a low complex situation (e.g., highways), or conversely a high complex situation (e.g., town) can provoke an overload. Additionally, performing the driving tasks implies producing a high effort for novice drivers who have not totally automated the driving activity. In the second part, we will focus on subjective measures of mental workload. A comparison of questionnaires usually used in driving will allow identifying the most appropriate ones as a function of different criteria. Moreover, we will review the empirical studies to verify if the subjective level of mental workload is high in simple and very complex situations, especially for novice drivers compared to the experienced ones. In the third part, we will focus on physiological measures. A comparison of physiological indicators will be realized in order to identify the most correlated to mental workload. An empirical review will also take the effect of situation complexity and experience on these physiological indicators into consideration. Finally, a more nuanced comparison between subjective and physiological measures will be established from the impact on situation complexity and experience. (shrink)

The New Keynesian framework has emerged as the workhorse for the analysis of monetary policy and its implications for inflation, economic fluctuations, and welfare. It is the backbone of the new generation of medium-scale models under development at major central banks and international policy institutions, and provides the theoretical underpinnings of the inflation stability-oriented strategies adopted by most central banks throughout the industrialized world. This graduate-level textbook provides an introduction to the New Keynesian framework and its applications to monetary policy. (...) Using a canonical version of the New Keynesian model as a reference framework, Jordi Galí explores issues pertaining to the design of monetary policy, including the determination of the optimal monetary policy and the desirability of simple policy rules. He analyzes several extensions of the baseline model, allowing for cost-push shocks, nominal wage rigidities, and open economy factors. In each case, the implications for monetary policy are addressed, with a special emphasis on the desirability of inflation targeting policies.The most up-to-date and accessible introduction to the New Keynesian framework available Uses a single benchmark model throughout Concise and easy to use Includes exercises An ideal resource for graduate students, researchers, and market analysts.

This article is a personal and professional meditation on Zolberg's work regarding pluralism, heterogeneity, and his relation to The New School, historically situated.

Recently at least two papers1,2have appeared that look at cancer from an evolutionary perspective. That cancer has a negative effect on fitness needs no argument. However, cancer origination is not an isolated process, but the potential for it is linked in diverse ways to other genetically determined developmental events, complicating the way selection acts on it, and through it on the evolution of development. The two papers take a totally different line. Kavanagh argues that anti‐cancer selection has led to developmental (...) constraints. Leroi et al. argue that cancer is a side‐effect of recent evolutionary changes that usually will disappear over time through anti‐cancer selection. Here we place the papers in a wider perspective, and in so doing discuss various alternative developmental links cancer may have together with their evolutionary implications.

The process of translation has both an excluding and including character. The analysis of actor networks, the process of mobilizing alliances, and constructing networks is a common and worthwhile focus. However, the simultaneous betrayals, dissidences, and controversies are often only implied in network construction stories. We aim to nuance the construction aspect of actor–network theory by shining the analytical searchlight elsewhere, where the theoretical tools of ANT have not yet systematically ventured. We argue that we need to understand every process (...) of translation in relation to its simultaneous process of treason, and to add antonyms for Callon’s problematization, intressement, enrollment, and mobilization. This enables us to describe powerlessness not as a state but as a process. Our case focuses on the network building around measures for disabled people in the construction of the Athens Metro, during the period 1991-1993. The discussion highlights the efforts of disability organizations to intervene in the initial construction works of the metro project and the simultaneous actions of the Greek government to exclude disability organizations from the design process and to disrupt the accessibility-metro actor network.

This paper emplaces arguments about affirmative action today inside a history of racial harms inflicted by public policy during the last heyday of southern power in Congress in the 1930s and 1940s. Showing how social programs utilized occupational exclusions and administrative decentralization to protect the Jim Crow racial order, it argues that assertive remedies can be found that connect the ambitions for affirmative action announced by President Lyndon Johnson at Howard University in 1965 with the principles enunciated by Justice Lewis (...)

This collection of essays, originally published in 1970 by Random House, gathers together some of the best initial responses to the problems raised by Edmund Gettier's celebrated critique of the traditional analysis of knowledge. Designed for upper-level courses and seminars in undergraduate philosophy programs and is intended as an introduction to epistemology from the analytic point of view.

What is the “conventional sense” of disability, and how do the questions addressed in this special issue of Science, Technology, & Human Values differ from those inspired by Donna Haraway and the cyborg? In industrialized societies, the medical profession has authority over the determination of who should count as disabled while “assistive technologies” enable specific kinds of subject positions. In this special issue of STHV, the focus of the essays as a whole is on the different enactments of disability, as (...) complexity that simultaneously implicates bodies, gender, sexuality, technology, and politics. The study of disability offers scope for refinement and further articulation of many issues of long-standing concern to science, technology, and society. In addition, we hope they will encourage further reflection on our field’s normative engagement. (shrink)
