Public spheres research has traditionally sidestepped questions of space by focusing on a priori delineated political territories, most prominently national public spheres. While this approach has always lacked nuance, it has become acutely insufficient nowadays, as digital communication technologies easily enable a host of heterogeneous actors to draw public attention to spaces and places at any scale, and communicatively connect places anywhere in the world. This conceptual article argues that communication scholars need to reconsider the spaces embedded in the content of public discourses. Drawing on the notion of issue publics, it understands the public definition of issues as inextricably linked to the places that are communicatively associated with them, causing issue spaces to emerge. The issue space is constructed through place-naming whenever public actors reference places in the context of issues. The article develops issue spatiality as an analytical framework to understand the role of place and space in public discourse. It discusses how issue spatiality enables a better understanding of the increasingly complex scales of public communication, and outlines several dimensions of issue spatiality. Drawing on communication infrastructure literature, it proposes socio-spatial inequalities of communicative resources as important predictors of issue spatiality, along with the habits of professional communicators, and local problem properties. Gazetteers and mapping techniques are introduced as methodological interventions required for the empirical use of issue spatiality.

Machine Leraning

Computational censorship in the form of fake news and toxic comments regulation is a subject that comes up quite often in the public discourse, as a result of the volatile political circumstances on a global scale and due to the unquestionable impact of journalism on these circumstances. Public attention has been directed to the role of mainstream and other media in the formation of public opinion, either in the form of articles or in the form of usergenerated comments. The purpose is to analyse and allow a deeper understanding of a project that is under development, namely, computational-censorship and to show that algorithmic regulation is not a solution, but rather another layer to a more fundamental problem. This article examines the implicationsof developing Machine Leraning/Artificial Iintelligence (ML/AI) which aims to regulate the internet and we attempt to allow a glimpse into the technical aspect of the problem as a way to back arguments that could be re-jected by the ML/AI research community as “non-pragmatic”. Finally, it aims to highlight the absurdity of the current approach to research in this area, which is the exact opposite of the rationalism that the field claims to be embracing.

Interdisciplinary Scholarship

Public spheres are sites of communicative interaction that feature citizens turning their attention to collective problems and democratically legitimate solutions. Closely associated with German critical theorist Jürgen Habermas, the idea of public spheres constituted by a range of publics and counterpublics animates a broad array of interdisciplinary scholarship relating to democracy and political theory, argumentation and deliberation, citizenship and civic engagement, media ecologies and the press, and institutions and power relations. Habermas originally theorized the emergence of the bourgeois public sphere as a counterpoint to the aristocratic regimes of early modern Europe, aiming to rescue select democratic practices from an otherwise flawed ideology. Critics of Habermas’s early formulation of the bourgeois public sphere have noted the presence of a multiplicity of public spheres, rather than a single public sphere, the problem of the public/private divide that is definitive of the public sphere, the role of bodies and emotions in addition to language and reason in the formation and operation of publics and counterpublics, the role of media technologies in sustaining and expanding critical publicity, and the difficulties in extracting knowledge claims from the power relations that constitute them. The idea of public spheres has remained resilient despite these criticisms, as any functioning democracy requires a space between the family, the market, and the state to thematize, problematize, and address the challenges of life in groups. Strong public spheres are characterized by hospitality to counterpublics, groups that distinguish themselves from the rational-critical debate of dominant publics through different dispositions, styles, and strategies for steering public attention. Scholarship on public spheres, publics, and counterpublics continues to proliferate, with new directions accounting for the increased prominence of visuality, ecology, digitality, and transnationality in deliberating bodies.

Although ego-centered network data provide information that is limited in various ways as compared with full network data, an ego-centered design can be used without the need for a priori and researcher-defined network borders. Moreover, ego-centered network data can be obtained with traditional survey methods. However, due to the dynamic structure of the questionnaires involved, a great effort is required on the part of either respondents (with self-administration) or interviewers (with face-to-face interviews). As an alternative, we will show the advantages of using CASI (computer-assisted self-administered interview) methods for the collection of ego-centered network data as applied in a study on the role of social networks in substance use among college students.

Religious Symbolism

The role of Islamic intellectuals is not confined to elaborating on the religious ideology of Islam. Equally important is their role in setting this religious ideology against other ideologies, sharpening and clarifying their differences, and thereby developing and intensifying one’s commitment to Islam as a distinct, divinely based ideology. Islam, as both a religion and an ideology, simultaneously mobilizes and transforms, legitimizes and preserves. It can be an instrument of power, a source and a guarantee of its legitimacy, as well as a tool to be used in the political struggle among social classes. Islam can also present a challenge to authority whenever the religious movement questions the existing social order during times of crisis and raises a rival power, as the current situation in Sudan vividly demonstrates. Throughout his political career, Hassan al-Turabi has resorted to religious symbolism in his public discourse and/or Islamic rhetoric, which could often be inflammatory and heavily reliant upon the Qur’an. This is, in fact, the embodiment of the Islamic quest for an ideal alternative. Our paper focuses on this charismatic and pragmatic religio-political leader of Sudan and the key concepts of his religious discourse: faith (īmān), renewal (tajdīd), and ijtihād(rational, independent, and legal reasoning).

Goal Directed Behavior

Rapid instructed task learning (RITL) is the uniquely human ability to transform task information into goal-directed behavior without relying on trial-and-error learning. RITL is a core cognitive process supported by functional brain networks. In patients with schizophrenia, RITL ability is impaired, but the role of functional network connectivity in these RITL deficits is unknown. We investigated task-based connectivity of eight a priori network pairs in participants with schizophrenia ( n = 29) and control participants ( n = 31) during the performance of an RITL task. Multivariate pattern analysis was used to determine which network connectivity patterns predicted diagnostic group. Of all network pairs, only the connectivity between the cingulo-opercular network (CON) and salience network (SAN) during learning classified patients and control participants with significant accuracy (80%). CON-SAN connectivity during learning was significantly associated with task performance in participants with schizophrenia. These findings suggest that impaired interactions between identification of salient stimuli and maintenance of task goals contributes to RITL deficits in participants with schizophrenia.

Great Development

Over the last few years, mobile robotics has experienced a great development thanks to the wide variety of problems that can be solved with this technology. An autonomous mobile robot must be able to operate in a priori unknown environments, planning its trajectory and navigating to the required target points. With this aim, it is crucial solving the mapping and localization problems with accuracy and acceptable computational cost. The use of omnidirectional vision systems has emerged as a robust choice thanks to the big quantity of information they can extract from the environment. The images must be processed to obtain relevant information that permits solving robustly the mapping and localization problems. The classical frameworks to address this problem are based on the extraction, description and tracking of local features or landmarks. However, more recently, a new family of methods has emerged as a robust alternative in mobile robotics. It consists of describing each image as a whole, what leads to conceptually simpler algorithms. While methods based on local features have been extensively studied and compared in the literature, those based on global appearance still merit a deep study to uncover their performance. In this work, a comparative evaluation of six global-appearance description techniques in localization tasks is carried out, both in terms of accuracy and computational cost. Some sets of images captured in a real environment are used with this aim, including some typical phenomena such as changes in lighting conditions, visual aliasing, partial occlusions and noise.

The Impact

BackgroundThe COVID-19 pandemic has asked unprecedented questions of governments around the world. Policy responses have disrupted usual patterns of movement in society, locally and globally, with resultant impacts on national economies and human well-being. These interventions have primarily centred on enforcing lockdowns and introducing social distancing recommendations, leading to questions of trust and competency around the role of institutions and the administrative apparatus of state. This study demonstrates the unequal societal impacts in population movement during a national ‘lockdown’.MethodsWe use nationwide mobile phone movement data to quantify the effect of an enforced lockdown on population mobility by neighbourhood deprivation using an ecological study design. We then derive a mobility index using anonymised aggregated population counts for each neighbourhood (2253 Census Statistical Areas; mean population n=2086) of national hourly mobile phone location data (7.45 million records, 1 March 2020–20 July 2020) for New Zealand (NZ).ResultsCurtailing movement has highlighted and exacerbated underlying social and spatial inequalities. Our analysis reveals the unequal movements during ‘lockdown’ by neighbourhood socioeconomic status in NZ.ConclusionIn understanding inequalities in neighbourhood movements, we are contributing critical new evidence to the policy debate about the impact(s) and efficacy of national, regional or local lockdowns which have sparked such controversy.

AbstractIn this paper, I analyze the role of metaphors in public science communication. Specifically, it is a case study of the metaphors for CRISPR/Cas9, a controversial biotechnology that enables scientists to alter the DNA of any organism with unprecedented ease and has raised a number of societal, ethical and legal questions concerning its applications – most notably, on its usage on the human germline. Using a corpus of 600 newspaper articles from the British and German press, I show that there are striking differences in how these two European countries construe CRISPR in public discourse: the British press promotes the image of CRISPR as a word processor that allows scientists to edit the DNA, replacing spelling mistakes with healthy genes, whereas the German press depicts CRISPR as genetic scissors and thereby underlines the risk of mutations after cutting the DNA. I suggest that this contrast reflects differences in the legal frameworks of the respective countries and may influence the attitudes towards emerging biotechnologies among the British and German public.

Background: Health technologies have the potential to support the growing number of older adults who are aging in place. Many tools include visualizations (data visualizations, visualizations of physical representations). However, the role of visualizations in supporting aging in place remains largely unexplored.Objective: To synthesize and identify gaps in the literature evaluating visualizations (data visualizations and visualizations of physical representations), for informatics tools to support healthy aging.Methods: We conducted a search in CINAHL, Embase, Engineering Village, PsycINFO, PubMed, and Web of Science using a priori defined terms for publications in English describing community-based studies evaluating visualizations used by adults aged ≥65 years.Results: Six out of the identified 251 publications were eligible. Most studies were user studies and varied methodological quality. Three visualizations of virtual representations supported performing at-home exercises. Participants found visual representations either (a) helpful, motivational, and supported their understanding of their health behaviors or (b) not an improvement over alternatives. Three data visualizations supported understanding of one’s health. Participants were able to interpret data visualizations that used precise data and encodings that were more concrete better than those that did not provide precision or were abstract. Participants found data visualizations helpful in understanding their overall health and granular data.Conclusions: Studies we identified used visualizations to promote engagement in exercises or understandings of one’s health. Future research could overcome methodological limitations of studies we identified to develop visualizations that older adults could use with ease and accuracy to support their health behaviors and decision-making.
