Catching Reality or Bowing Disciplines: How to Move the Study of Citizenship

In his contribution, Joppke justifies his selection of foundational scholars by linking each to what he sees as the three key facets of citizenship: status, rights and identity. Maarten Vink explicitly links his research agenda to the first, status, and outlines why it is so important. In identifying three facets of citizenship, Joppke acknowledges that some academics would include political participation, but he ultimately decides against it. But here we can, and should, broaden citizenship studies by bringing in insights from the behavioral politics tradition in domestic politics - when and why people engage in political acts - and from the social movements literature in sociology. I believe that the American debate on immigration reform, admittedly stalled, would not have advanced as far as it has without the social movement activism of DREAMers - unauthorized young people pushing for a path to citizenship - and the belief that Barack Obama won re-election in part because of the Latino vote. Importantly, one type of political activism demands formal citizenship, the other does not. As many contributors note, the “national models” approach has had a significant impact on citizenship studies. Whether one views such models through a cultural, institutional or historical lens, this tends to be a top-down, macro-level framework. What about immigrants’ agency? In Canada, although the ruling Conservative government is shifting citizenship discourse to a more traditional language - as Winter points out - it has not reduced immigration, ended dual citizenship, or eliminated multiculturalism, all goals of the Reform Party that the current prime minister once helped build. “Lock-in” effects (or policy feedback loops) based on high immigrant naturalization and the coming of age of a second-generation with citizenship also d emands study, in North America and elsewhere. Much of the research thus far suggests that political decisions over citizenship status and rights do not seem linked to immigrants’ political activism. State-centered decision-making may have characterized policy in the early post-World War II period in Europe (and East Asia?), but does it continue to hold today? Majority publics and immigrant-origin residents are increasingly politicized around citizenship and immigration. Does immigrant agency extend citizenship status, rights and identity to those born outside the polity? Is electoral power key, or is protest necessary? How is citizenship practiced, and contested, irrespective of formal status? These are important and understudied empirical questions, ones that demand theoretical creativity - across sub-fields and disciplines - in conceptualizing and understanding citizenship in contemporary times.

Religion as Social Reality. A Take on the Emic–Etic Debate in Light of John Searle’s Philosophy of Society

In this article I argue that the shift from a private to a public–social understanding of religion raises new ontological and epistemological questions for the scientific study of religion\s. These questions are deeply related to three central features of the emic– etic debate, namely the problems of intentionality, objectivity, and comparison. Focusing on these interrelated issues, I discuss the potential of John Searle’s philoso- phy of society for the scientific study of religion\s. Considering the role of intentional- ity at the social level, I present Searle’s concept of “social ontology” and discuss its epistemological implications. To clarify Searle’s position regarding the objectivity of the social sciences, I propose a heuristic model contrasting different stances within the scientific study of religion\s. Finally, I explore some problematic aspects of Searle’s views for a comparative study of religion\s, and sketch a solution within his frame- work. I shall argue that a distinction between the epistemological and ontological dimensions of religious affairs would help clarify the issues at stake in the past and future of the emic–etic debate.

Keeping bugs in check: The mucus layer as a critical component in maintaining intestinal homeostasis

In the mammalian gastrointestinal tract the close vicinity of abundant immune effector cells and trillions of commensal microbes requires sophisticated barrier and regulatory mechanisms to maintain vital host-microbial interactions and tissue homeostasis. During co-evolution of the host and its intestinal microbiota a protective multilayered barrier system was established to segregate the luminal microbes from the intestinal mucosa with its potent immune effector cells, limit bacterial translocation into host tissues to prevent tissue damage, while ensuring the vital functions of the intestinal mucosa and the luminal gut microbiota. In the present review we will focus on the different layers of protection in the intestinal tract that allow the successful mutualism between the microbiota and the potent effector cells of the intestinal innate and adaptive immune system. In particular, we will review some of the recent findings on the vital functions of the mucus layer and its site-specific adaptations to the changing quantities and complexities of the microbiota along the (gastro-) intestinal tract. Understanding the regulatory pathways that control the establishment of the mucus layer, but also its degradation during intestinal inflammation may be critical for designing novel strategies aimed at maintaining local tissue homeostasis and supporting remission from relapsing intestinal inflammation in patients with inflammatory bowel diseases.

Design and Implementation of a Laparoscope Calibration Method for Augmented Reality Navigation

Intraoperative laparoscopic calibration remains a challenging task. In this work we present a new method and instrumentation for intraoperative camera calibration. Contrary to conventional calibration methods, the proposed technique allows intraoperative laparoscope calibration from single perspective observations, resulting in a standardized scheme for calibrating in a clinical scenario. Results show an average displacement error of 0.52 ± 0.19 mm, indicating sufficient accuracy for clinical use. Additionally, the proposed method is validated clinically by performing a calibration during the surgery.

Alexander’s Dictum and the Reality of Familiar Objects

Alexander's Dictum--"to be is to have causal powers"--appears to furnish an argument against the reality of familiar medium-sized objects. For every time a familiar object appears to cause a familiar macro-event, it sets up a rival claim by its component microparticles to have caused the complex swarm of microphysical events that composes into that macro-event. But this argument, argues this paper, wrongly assumes that even after familiar objects are removed from the picture, there is a phenomenon of joint causation which unites all and only the microparticles within each familiar object.

A Bootstrap-Regression Procedure to Capture Unit Specific Effects in Data Envelopment Analysis

The Data Envelopment Analysis (DEA) efficiency score obtained for an individual firm is a point estimate without any confidence interval around it. In recent years, researchers have resorted to bootstrapping in order to generate empirical distributions of efficiency scores. This procedure assumes that all firms have the same probability of getting an efficiency score from any specified interval within the [0,1] range. We propose a bootstrap procedure that empirically generates the conditional distribution of efficiency for each individual firm given systematic factors that influence its efficiency. Instead of resampling directly from the pooled DEA scores, we first regress these scores on a set of explanatory variables not included at the DEA stage and bootstrap the residuals from this regression. These pseudo-efficiency scores incorporate the systematic effects of unit-specific factors along with the contribution of the randomly drawn residual. Data from the U.S. airline industry are utilized in an empirical application.

Análisis de la evolución de los resultados de los alumnos y la metodología Bootstrap para detección de cambios

En este trabajo nos enfocamos en el problema del punto de cambio aplicado al control de calidad del proceso enseñanza-aprendizaje. Para ello se tomo en cuenta la evolución temporal de la proporción de alumnos promocionados, por cuatrimestre, de la asignatura Estadística de la Facultad de Ingeniería de la UNLP, desde el año 2001 al 2008. El objetivo es analizar la posible aparición de cambios en dicha proporción no detectados por las cartas de control convencionales. Se trata de establecer las posibles causas de esos cambios en el marco de las transformaciones ocurridas a partir de la acreditación de las carreras de Ingeniería de la UNLP, usando estas herramientas de estudio. El análisis de punto de cambio es una novedosa herramienta utilizada con el fin de determinar la existencia o no de cambios en procesos de diferente índole. Para su aplicación se emplea un test de hipótesis y la metodología Bootstrap.
