Polarization of COVID-19 Vaccine Discourse on Twitter: Implications for Vaccine Policy (Preprint)

UNSTRUCTURED Since COVID-19 vaccines became broadly available to the adult population, sharp divergences in uptake have emerged along partisan lines. Researchers have pointed to a polarized social media presence contributing to the spread of mis-/dis-information as being responsible for these growing partisan gaps in uptake. The major aim of this study was to identify and describe influential actors, topics, behaviors, and community structures related to COVID-19 vaccine conversations on Twitter prior to the vaccine roll-out to the general population and discuss implications for vaccine promotion and policy. Using Twitter data on COVID-19 vaccination during July 2020, we found that Twitter vaccine conversations were highly polarized with different actors occupying separate “clusters.” The anti-vaccine cluster was the most densely connected group. Among the 100 most influential actors, medical experts are outnumbered both by partisan actors and by activist vaccine skeptics/conspiracy theorists. Scientists and medical actors were largely absent from the conservative network, and anti-vaccine sentiment was especially salient among actors on the political right. Conversations related to COVID-19 vaccines are highly polarized along partisan lines with “trust” in vaccines being manipulated to the political advantage of partisan actors.

Anatolian-Persian grave stelae from Bozüyük in Phrygia: a contribution to understanding Persian presence and organisation in the region

This paper provides an assessment of four grave stelae that were found recently in the area surrounding Bozüyük, on the Anatolian plateau in the south of the Bilecik province. The plateau was part of the core of the kingdom of Phrygia during the Early and Middle Iron Ages, and part of the satrapy of Phrygia during the Achaemenid period of the Late Iron Age in Anatolia. The main focus is to examine the place of such stelae among Anatolian-Persian examples and to explore elements of Persian presence and organisation in the region. The precise archaeological contexts of these stelae are unknown, but are likely to have been tumuli. They are examples of an Anatolian-Persian style from the Achaemenid period, but can also be considered to be part of a somewhat rustic 'rural' sub-style, compared with more elaborate stelae that have been found around Dascylium, the satrapal capital of Hellespontine Phrygia. The Bozüyük stelae feature banquet, hunting and ritual scenes, and also battle scenes that distinguish them from other Anatolian-Persian stelae. Despite similarities, particularly with the Vezirhan stele, there are also discrepancies that make precise analogies with reliefs on other stelae difficult, though not impossible. It is likely that they were created by a connected group of sculptors, and might therefore be evidence of a workshop that sculpted local materials in a unique rural style.

R-GROUP AND WHITTAKER SPACE OF SOME GENUINE REPRESENTATIONS

For a unitary unramified genuine principal series representation of a covering group, we study the associated R-group. We prove a formula relating the R-group to the dimension of the Whittaker space for the irreducible constituents of such a principal series representation. Moreover, for certain saturated covers of a semisimple simply connected group, we also propose a simpler conjectural formula for such dimensions. This latter conjectural formula is verified in several cases, including covers of the symplectic groups.

Intermediality and the City Text: Towards an Analysis of a “City Picture”

This paper attempts to examine a specific type of text, called the “city picture”, by use of intermedial methodology. Firstly, it distinguishes between the “city text” and the “city picture”: the latter is understood as a particular type of urban text, which structural and semantic element is represented in a text, or its fragment, by the image of the city. The urban text is defined as both a system of signs (“the city as text”, in a semiotic perspective) and as a semantically connected group of texts about the city. Then follows an analysis of the main approaches to the intermedial study to identify the tools for further work. The prerequisites for the study of the urban text in the perspective of intermedial approach are the interdisciplinary nature of the urban text and the inclusion of the visual component both in the concept of the “city picture” itself and in the selected texts. On the example of the works Ch. Baudelaire, A. Bertrand, L.-S. Mercier, É. Verhaeren, G. Rodenbach the author tries to analyze different types of intermedial connections that the “city picture” can create. This includes an analysis of the relationships between literature and painting in selected works, then in the illustrated editions, as well as a “reverse” medial transition into the field of visual art. In the end it concludes that the described approach is applicable for the analysis of urban texts.

Does Online Social Connectivity Promote Physical Activity in a Wearable Tracker-Based Intervention? A Pilot Randomized Controlled Study

Wearable activity trackers have gained popularity among individuals who want to track their physical activity (PA). The features of wearable tracking technology that are known to facilitate positive behavior changes such as self-monitoring and social connectedness) are well documented; yet, the existing evidence is not conclusive in the literature requiring further investigation. This study was an 8-week pilot randomized controlled study examining the effectiveness of PA intervention incorporating a wearable activity tracker’s online connectivity feature. Forty participants were equally randomized into either an individual-based (n = 20) or a connected group (n = 20). A Jawbone UP24 tracker was provided to all participants in both groups as a means of self-monitoring PA for eight weeks, but the connected group was additionally instructed to share their PA levels with the others using the accompanying smartphone application. Participants’ weekly step counts were evaluated each week to examine the change in PA. Participants’ biometric variables such as body weight, body mass index, waist circumference, blood pressure, and psychological status, including self-efficacy (SE) and exercise motivation (EM), were measured from both groups before and after the intervention period. Additionally, the social support questionnaire (SSQ) was measured among the connected group. The statistical significance level was set at <0.05. The average step counts for eight weeks were significantly increased only in the connected group (p < 0.001). Significant differences in step count improved from the baseline to week 8 in the connected user group (p < 0.01), but only baseline vs. week 7 in the individual users. Also, no significant interaction effects for biometric variables, EM, and SE were founded. However, SSQ was significantly improved in the connected user group (p < 0.001). PA intervention combining a wearable activity tracker and online social connectivity feature shows a greater effectiveness of promoting PA than a wearable tracker alone

Early American Rebels

During the half century after 1650 that saw the gradual imposition of a slave society in England’s North American colonies, poor white settlers in the Chesapeake sought a republic of equals. Demanding a say in their own destinies, rebels moved around the region looking for a place to build a democratic political system. This book crosses colonial boundaries to show how Ingle's Rebellion, Fendall's Rebellion, Bacon's Rebellion, Culpeper's Rebellion, Parson Waugh's Tumult, and the colonial Glorious Revolution were episodes in a single struggle because they were organized by one connected group of people. Adding land records and genealogical research to traditional sources, Noeleen McIlvenna challenges standard narratives that disdain poor whites or leave them out of the history of the colonial South. She makes the case that the women of these families played significant roles in every attempt to establish a more representative political system before 1700. McIlvenna integrates landless immigrants and small farmers into the history of the Chesapeake region and argues that these rebellious anti-authoritarians should be included in the pantheon of the nation’s Founders.

Do firms harvest from political connections during general elections? Case of Pakistan

Purpose This paper aims to examine the impact of general elections on the stock returns of the politically connected group affiliated firms of Pakistan. Design/methodology/approach This study uses the market model to assess the impact of political connections (PCs) on abnormal stock returns, before and after election events. We have used share price data of non-financial firms of Pakistan for the years 2008-2013. Findings It has been found that behavior of cumulative average abnormal returns (CAAR) is significantly different for standalone and politically connected group affiliated firms. The results reveal that CAARs of politically connected group affiliated firms have experienced less deviation as compared to stand alone firms. Therefore, it is argued that politically connected group firms may reduce the impact of political uncertainty on stock returns in comparison to stand alone firms. Practical implications This study is helpful for policy regulators of Pakistan to devise appropriate policies to maintain a level playing field for politically connected and standalone firms. Originality/value This study provides a new dimension to understand the role and association of PCs and general elections with stock markets returns.
