1	Holy day effects on language: How religious geography, individual affiliation and day of the week relate to sentiment and topics on Twitter Kramer, Stephanie 10 April 2018 (has links) Religious belief and attendance predict improved well-being at the individual level. Paradoxically, geographic locations with high rates of religious belief and attendance are often those with the differentially high rates of societal instability and suffering. Many of the consequences of religiosity are context-based and vary across time, and holy days are naturally-occurring religious cues that have been shown to influence religiously-relevant attitudes and behaviors. I investigated the degree to which personal religiosity and religious geography (i.e. religious demographics with other location variables) individually and interactively predict well-being across days of the week. In the first study, American Christians demonstrated greater well-being by expressing more positive sentiment in Twitter posts, while American Muslims displayed less well-being. Sundays were generally the most positive day, but American Muslims communicated more happiness on Fridays (the Muslim holy day). In the second study, Christianity did not predict increased well-being in the posts of college students. In the third study, global survey data with measures of religiosity and well-being indicated that the well-being consequences of religious affiliation depend on the religious group and location, and that people tend to be especially positive on their group’s holy day. Study four explored the latent topical content of Twitter posts. Across studies, religious minority status appeared to have a deleterious effect on well-being.

2	Unearthing the social-ecological cascades of the fall armyworm invasion: A computer-assisted text analysis of digital news articles Bjorklund, Kathryn January 2023 (has links) Understanding the complex nature of social-ecological cascades, or chain reactions of events that lead to widespread change in a system, is crucial for navigating the challenges they present. Emerging pests and pathogens, such as the fall armyworm, provide an opportunity to study these cascades in greater detail. I use topic modeling of digital news articles to investigate the potential social-ecological cascades associated with the ongoing fall armyworm invasion of multiple geographic regions. My findings reveal regional thematic shifts in the popular news media discourse surrounding the fall armyworm invasion. Notably, in the discourse surrounding Oceania, I observed a pronounced focus on invasion preparation, a theme significantly more emphasized compared to regions like Africa and Asia. These regional variations shed light on some of the localized priorities in addressing this invasive species. By highlighting the significance of employing comprehensive case studies of emerging pests and pathogens, this research underscores the need for more in- depth analyses of social-ecological cascades to better manage and mitigate their impacts. emerging pests and pathogens social-ecological cascades fall armyworm Spodoptera frugiperda structural topic modeling Environmental Sciences Miljövetenskap Social Sciences Interdisciplinary
3	The Salience of Issues in Parliamentary Debates : Its Development and Relation to the Support of the Sweden Democrats Alexander, Ödlund Lindholm January 2020 (has links) The aim of this study was to analyze the salience of issue dimensions in the Swedish parliament debates by the established parties during the rise of the Sweden Democrats Party (SD). Structural topic modeling was used to construct a measurement of the salience of issues, examining the full body of speeches in the Swedish parliament between September 2006 and December 2019. Trend analysis revealed a realignment from a focus on socio-economic to socio-cultural issues in Swedish politics. Cross-correlation analyses had conflicting results, indicating a weak positive relationship between the salience of issues and the support of SD – but low predictive ability; it also showed that changes in the support of SD did lead (precede) changes in the salience of issues in the parliament. The ramifications of socio-cultural issues being the most salient are that so-called radical right-wing populist parties (RRPs), or neo-nationalist parties, has a greater opportunity to gain support. It can make voters more inclined to base their voting decision on socio-cultural issues, which favors parties who fight for and are trustworthy in those issues – giving them more valence in the eyes of the voters.
