Disruptive Technologies, Social Transformation and the Sociological Imagination

I outline a conceptual framework for the sociological study of ‘disruptive technologies’ in the digital age. My starting point begins with a sociological framing of these phenomena through the mobilization of classic sociological questions; namely how is social organisation possible? why do societies change over time? and what type(s) of identity are promoted in a given social form?

‘Disruptive’ technologies include Social Media, Big Data, Robotics and new forms of Additive Manufacture.

This presentation moves to respecify these technological developments within the context of the emerging contours of digital society (Edwards et al 2013, Housley et al, 2014, Housley, 2015). In doing so sociology is brought to the fore as an explanatory apparatus that operationalises theory, method and data in ways that account for the re-ordering of social relations in the digital age. Furthermore, matters relating to method and new forms of data, automation and predictive analytics are attended to as routine features of the digital imaginary where ‘disruptive technologies’ are understood as data generative, algorithmic, networked, distributed and organizing socio-technical assemblages. These discursive and material assemblages are ‘motile’ and are underpinned by an array of digital data imaginaries that envision new forms of relating, governing, working and being in a re-ordered and digitally colonised institutional landscape within which digital crowds and mass are being re-materialized. As a consequence disruptive technologies are reconsidered as social and cultural forces in their own right.

Choosing Faith and Facing Race: Converting to Islam in France and the United States

Juliette Galonnier (OSC)This research is about race and religion. While scholars typically understand them separately, I propose instead to explore occurrences in which they are conflated. Specifically, I track instances of racial reasoning that occur in relation to the religion of Islam in Western societies, by focusing on the specific experiences of Muslim converts. By crossing religious boundaries, converts shed light on the nature and content of such boundaries, and enable us to decide whether they are simply religious or also embody racial difference. The case of white converts is particularly interesting: because their conversion implies transitioning from one social status (majority) to another (minority), they offer a near-experimental case to investigate how racial categorization operates.

Methodologically, I combine the meticulousness of qualitative methods with the bird’s eye view of comparatism. Using in-depth interviewing with 82 converts in France and the United States; ethnographic observations in convert associations in Paris and Chicago; and content analysis of media and historical documents, I compare the past and present experiences of French and American converts to answer the following: how and when is conversion to Islam interpreted in terms of changing one’s racial status rather than a mere change in religious orientation? In addition to shedding light on the complex interplay between race and religion, this research contributes to transatlantic comparative scholarship, by highlighting differences across the French and American contexts in the conversion process, the encounter with race and the strategies used by converts to reclaim control over their definition of self.

Cette thèse offre un éclairage sur l’articulation des catégories raciales et religieuses dans la construction de la différence. Elle porte sur le processus de « racialisation » de l’islam dans les sociétés occidentales, analysé à partir de l’expérience particulière des convertis à cette religion. En traversant les frontières religieuses, les convertis nous renseignent sur la nature de ces frontières, et permettent de déterminer si elles sont purement religieuses ou incarnent également une altérité de type racial. A cet égard, le cas des convertis dits « blancs » se révèle heuristique : en tant que membres de la société majoritaire ayant choisi une religion minoritaire, ils représentent un cas quasi-expérimental pour analyser les processus de catégorisation raciale en lien avec l’appartenance religieuse. En s’appuyant sur 82 entretiens biographiques avec des converti-e-s en France et aux États-Unis, des observations ethnographiques dans des associations de convertis à Paris et Chicago, et l’analyse de documents historiques et médiatiques, cette recherche compare les expériences passées et présentes des convertis français et américains pour répondre à la question suivante : quand et comment la conversion est-elle interprétée en termes de changement de statut racial, plutôt que comme un simple changement d’orientation religieuse ? En plus de démêler l’imbrication entre catégories raciales et religieuses, cette thèse met également en lumière les spécificités des contextes français et américain, en identifiant des différences dans le processus de conversion, le rapport aux assignations raciales, et les stratégies que les convertis mobilisent pour contrer leur objectification.

The Scholar Denied:
W.E.B. Du Bois and the Birth of Modern Sociology

Pr. Aldon Morris, Leon Forrest Professor of Sociology and African American Studies, Northwestern University

Pr. Aldon Morris (Northwestern University)W.E.B. Du Bois was one of a handful of scholars of the 20th century with a sustained global impact on sociological, literary, and political knowledge. In this book, Morris draws on primary evidence to demonstrate that Du Bois was the founding father of scientific sociology in the United States; that is, American scientific sociology was founded in a segregated black university by a black man. This book disconfirms the accepted wisdom that American scientific sociology was founded solely by white sociologists in elite universities. The Scholar Denied explores the methods Du Bois pioneered, his novel theorizing, and his influence on other scholars including Franz Boas and Max Weber. The Scholar Denied (Uiversity of California Press)This book reveals the extraordinary efforts that Robert E. Park and the Chicago School of Sociology took to marginalize the original scientific contributions of Du Bois’ prolific work. Morris’ book offers an account of the dynamic, but neglected forces, which generate scientific schools of thought and undergirded knowledge production in social science during the twentieth century.

Inequalities and Social Class:
Topics, Main Paradigms and Future Development

Sciences Po, 29-30 june 2017

Caquot amphitheatre (28, rue des Saints-Pères)

Provisional Program

Do we still live in class societies? Is the classical approach to social inequalities, political divisions and lifestyles still relevant?

Do we still live inside class societies? Is the classical approach to social inequalities, political cleavages or lifestyles still relevant?

This conference, organized over two full days at the initiative of the Center for Studies in Social Change (OSC), calls into question the current concept of “class” in the contemporary social sciences. It will bring together specialists from a wide range of thematics, theoretical and methodological backgrounds. With a broad international lens, the conference will draw on the comparison of various national contexts (including United States, United Kingdom, India, Brazil, Argentina).
Throughout the contributions, we will examine the explanatory power of the different existing theoretical models and their renewal, in contexts that are often disconnected from the European and North-American framework in which these theories were initiated and developed in the 19th and 20th centuries. Attention will be paid both to the generating mechanisms of class relations and their inclusion in various domains of social life: politics, lifestyles, and geography, especially within urban areas and large metropolises. The conference will focus specifically on the relationships between changes in the wealth distribution (the soar in high-income, the increased importance of heritage) and contemporary transformations of class boundaries and class relations. Emphasis will also be placed on the articulation between the division of society into classes and social mobility trajectories. Two cross-cutting questions will be central to these inquiries: what sort of theories of social class are relevant for the 21st century? How can micro (ethnographic, qualitative) and macro-social (quantitative, structural) approaches be used in a complementary way?
The format of the conference (about fifteen speakers) will allow time for open discussion between the speakers and all conference participants. Papers will be presented in English.

Papers will be presented in English.
