This article investigates how communications advances affect citizens’ ability to participate in coproduction of government services. The authors analyze service requests made to the City of Boston during a one‐year period from 2010 to 2011 and, using geospatial analysis and negative binomial regression, investigate possible disparities by race, education, and income in making service requests. The findings reveal little concern that 311 systems (nonemergency call centers) may benefit one racial group over another; however, there is some indication that Hispanics may use these systems less as requests move from call centers to the Internet and smartphones. Consistent with prior research, the findings show that poorer neighborhoods are less likely to take advantage of 311 service, with the notable exception of smartphone utilization. The implications for citizen participation in coproduction and bridging the digital divide are discussed.  相似文献

Abstract

This paper interrogates influential contemporary accounts of interdisciplinarity, in which it is portrayed as offering new ways of rendering science accountable to society and/or of forging closer relations between scientific research and innovation. The basis of the paper is an eighteen-month empirical study of three interdisciplinary fields that cross the boundaries between the natural sciences or engineering, on the one hand, and the social sciences or arts, on the other. The fields are: 1) environmental and climate change research, 2) ethnography in the IT industry and 3) art-science. In the first part of the paper, in contrast to existing accounts, we question the idea that interdisciplinarity should be understood in terms of the synthesis of two or more disciplines. We stress the forms of agonism and antagonism that often characterize relations between disciplinary and interdisciplinary research, and distinguish between three modes of interdisciplinarity. In the second part we outline three distinctive logics or rationales that guide interdisciplinary research. In addition to the logics of accountability and innovation, we identify the logic of ontology, that is, an orientation apparent in diverse interdisciplinary practices in each of our three fields towards effecting ontological transformation in the objects and relations of research. While the three logics are interdependent, they are not reducible to each other and are differently entangled in each of the fields. We point to the potential for invention in such interdisciplinary practices and, against the equation of disciplinary research with autonomy, to the possibility of forms of interdisciplinary autonomy.  相似文献

The doubly randomized preference trial (DRPT) is a randomized experimental design with three arms: a treatment arm, a control arm, and a preference arm. The design has useful properties that have gone unnoticed in the applied and methodological literatures. This paper shows how to interpret the DRPT design using an instrumental variables (IV) framework. The IV framework reveals that the DRPT separately identifies three different treatment effect parameters: the Average Treatment Effect (ATE), the Average Treatment Effect on the Treated (ATT), and the Average Treatment Effect on the Untreated (ATU). The ATE, ATT, and ATU parameters are important for program evaluation research because in realistic settings many social programs are optional rather than mandatory and some people who are eligible for a program choose not to participate. Most of the paper is concerned with the interpretation of the research design. To make the ideas concrete, the final section provides an empirical example using data from an existing DRPT study.  相似文献
