Trans-Science as a Vocation

This paper compares Weber’s argument in “Science as a vocation,” with Physicist Alvin Weinberg’s discussion of the distinction between science and “trans-science,” as two contrasting blueprints for boundary-work. It argues that Weber’s empirical reasons for separating the scientific discussion of means and the extra-scientific discussion of ends – namely, the thesis of “disenchantment” – no longer serves as a useful approach to understanding the growth of “trans-science” or “expertise” over the last century. It advances an understanding of the latter as an intermediary sphere wherein facts and values, means and ends, are necessarily entangled because expertise is crucial to the production of legitimacy in liberal-democratic societies. The paper concludes by asking what is the responsibility of the scientist as trans-scientist or expert and what institutions would best embody and support this vocation

Driving induced many-body localization

Subjecting a many-body localized system to a time-periodic drive generically leads to delocalization and a transition to ergodic behavior if the drive is sufficiently strong or of sufficiently low frequency. Here we show that a specific drive can have an opposite effect, taking a static delocalized system into the many-body localized phase. We demonstrate this effect using a one-dimensional system of interacting hardcore bosons subject to an oscillating linear potential. The system is weakly disordered, and is ergodic absent the driving. The time-periodic linear potential leads to a suppression of the effective static hopping amplitude, increasing the relative strengths of disorder and interactions. Using numerical simulations, we find a transition into the many-body localized phase above a critical driving frequency and in a range of driving amplitudes. Our findings highlight the potential of driving schemes exploiting the coherent suppression of tunneling for engineering long-lived Floquet phases.Comment: 9 pages, 9 figure

Learning phase transitions from dynamics

We propose the use of recurrent neural networks for classifying phases of matter based on the dynamics of experimentally accessible observables. We demonstrate this approach by training recurrent networks on the magnetization traces of two distinct models of one-dimensional disordered and interacting spin chains. The obtained phase diagram for a well-studied model of the many-body localization transition shows excellent agreement with previously known results obtained from time-independent entanglement spectra. For a periodically-driven model featuring an inherently dynamical time-crystalline phase, the phase diagram that our network traces in a previously-unexplored regime coincides with an order parameter for its expected phases.Comment: 5 pages + 3 fig, appendix + 5 fi

Looping Genomes: Diagnostic Change and the Genetic Makeup of the Autism Population

This article builds on Hacking’s framework of “dynamic nominalism” to show how knowledge about biological etiology can interact with the “kinds of people” delineated by diagnostic categories in ways that “loop” or modify both over time. The authors use historical materials to show how “geneticization” played a crucial role in binding together autism as a biosocial community and how evidence from genetics research later made an important contribution to the diagnostic expansion of autism. In the second part of the article, the authors draw on quantitative and qualitative analyses of autism rates over time in several rare conditions that are delineated strictly according to genomic mutations in order to demonstrate that these changes in diagnostic practice helped to both increase autism’s prevalence and create its enormous genetic heterogeneity. Thus, a looping process that began with geneticization and involved the social effects of genetics research itself transformed the autism population and its genetic makeup

Economic Indicators as Public Interventions

This essay argues that the term public intellectual is too narrow for historical research about the public influence of economists and economic expertise. We propose, instead, the concept of public interventions to inform a more comprehensive approach that broadens the analytical frame by multiplying the relevant actors, modes, and targets of intervention yet could still include within it research on public intellectuals narrowly construed. As an empirical example, we suggest that the design and diffusion of economic indicators—specifically, the GDP and the myriad indicators compiled in recent years as part of proposals to replace it with a better representation of human welfare—could be analyzed as a specific mode by which economists intervene in and shape the public sphere

“Forever Children” and Autonomous Citizens: Comparing the Deinstitutionalizations of Psychiatric Patients and Developmentally Disabled Individuals in the United States

Purpose We compare the deinstitutionalization of psychiatric patients and the developmentally disabled in the United States and demonstrate that there were two path-dependent processes with significant qualitative and quantitative differences, ultimately leading to better outcomes for developmentally disabled individuals. Design Using secondary literature, we construct a sustained comparison of the two processes in terms of outcomes, timing, tempo, extent, funding, demographic composition, and investment in community services. We then reconstruct the strategies of de-stigmatization and framings of moral worth deployed in the two cases, analyzing their effects on deinstitutionalization in terms of conceptions of risk, rights, and care. Findings Deinstitutionalization began later for developmentally disabled individuals than for psychiatric patients, and was a more gradual, protracted process. It was not driven by fiscal conservatism, discharges, and the trans-institutionalization of the senile aged, as was deinstitutionalization for psychiatric patients, but primarily by the prevention of institutionalization of young children, and increased investment in infrastructure. Consequently, the deinstitutionalization of the developmentally disabled was far more thorough and successful. The process was shaped by the framing of the developmentally disabled as “forever children” by parents’ organizations that demanded a balance between autonomy, protection, and the provision of care. In contrast, the deinstitutionalization of psychiatric patients was shaped by their framing as autonomous citizens temporarily suffering from “mental health problems” that could be prevented, treated, and cured. This frame foregrounded the right to choose (and also refuse) treatment, while undervaluing the provision of care

“Two Opposite Ends of the World”: The Management of Uncertainty in an Autism-Only School

How do individuals maintain a sense of efficacy and purpose in the face of high levels of ambiguity and uncertainty? In research on medical uncertainty, sociologists often discuss the strategies health practitioners employ to control uncertainties relating to diagnosis and treatment. Over six months of ethnographic field work at an autism-only therapy school, we observed seventy-five students and forty-seven instructors and formally interviewed ten instructors and four parents. While other studies on medical uncertainty have focused on controls over external circumstances, we demonstrate that another management strategy is for individuals to perform ethical work on themselves in order to adjust how they conduct themselves in uncertain situations. Despite the ambiguity of both the autism diagnosis and the therapeutic method employed at the school, instructors are able to maintain a sense of efficacy and to recognize themselves as “doing floortime” by transforming themselves to become “child directed.

The rise of randomized controlled trials (RCTs) in international development in historical perspective

This article brings a historical perspective to explain the recent dissemination of randomized controlled trials (RCTs) as the new "gold standard" method to assess international development projects. Although the buzz around RCT evaluations dates from the 2000s, we show that what we are witnessing now is a second wave of RCTs, while a first wave began in the 1960s and ended by the early 1980s. Drawing on content analysis of 123 RCTs, participant observation, and secondary sources, we compare the two waves in terms of the participants in the network of expertise required to carry out field experiments and the characteristics of the projects evaluated. The comparison demonstrates that researchers in the second wave were better positioned to navigate the political difficulties caused by randomization. We explain the differences in the expertise network and in the type of projects as the result of concurrent transformations in the fields of development aid and the economics profession. We draw on Andrew Abbott’s concept of "hinges," as well as on Bourdieu’s concept of "homology" between fields, to argue that the similar positions and parallel struggles conducted by two groups of actors in the two fields served as the basis for a cross-field alliance, in which RCTs could function as a "hinge" linking together the two fields
