Shaping Disease: Colonial Stigma And The Politics Of Health In Banyuwangi, The Early Twentieth Century, Rifa'i Shodiq Fathoni, Skriptyan Noor Hidayatullah Syuhri, Vini’Matu Hikmah, Ardhita Zahra Namira

Paradigma: Jurnal Kajian Budaya

This article examines the colonial stigma attached to Banyuwangi as an “unhealthy region” in the early 20th century, a label used to justify massive exploitation of its natural resources. Using a historical method, this research analyzes how this stigma not only served as a tool for colonial legitimation but also causatively created conditions that triggered ecological disasters and a public health crisis in a previously isolated area. Through an analysis of primary sources such as colonial reports, health journals, and newspapers, this article traces how large-scale plantation exploitation, enabled by the stigma, led to deforestation, uncontrolled labor migration, and poor …

Universalism And Exclusion: Immigrants Through The Lens Of French Law And Media, George Mikhael Taliak, Abellia Anggi Wardani Aug 2026

Universalism And Exclusion: Immigrants Through The Lens Of French Law And Media, George Mikhael Taliak, Abellia Anggi Wardani

Paradigma: Jurnal Kajian Budaya

This research examines France’s Immigration Law LOI n°2024-42 du 26 janvier 2024 and its representation in three mainstream media outlets across the ideological spectrum: Le Figaro (right), CCFD-Terre Solidaire (left), and France Info (center). Using Critical Discourse Analysis (Fairclough, 1995) and Maurice Halbwachs’s theory of collective memory, the study explores how legal and media discourses construct symbolic and administrative boundaries of national citizenship. Findings reveal that integration is framed not as civic inclusion, but as the internalization of a singular national identity and memory. Media reinforce this framework through divergent but convergent discursive strategies. At the macro level, the law …

Nihilistic Violence Aesthetics In Public Online Communication, Heath Nicholas Landress Aug 2026

Nihilistic Violence Aesthetics In Public Online Communication, Heath Nicholas Landress

Journal of Social, Behavioral, and Health Sciences

Public online communication has increasingly included violence-related content that is meme-based, ironic, visually stylized, multimodal, and only partially ideological. This comprehensive literature review synthesized research on online extremism, extremist memes, toxic multimodal content, dehumanizing digital communication, nihilistic violent extremism, warning behaviors, platform affordances, and youth-facing online environments. The purpose was to clarify what the literature had established; identify where the scholarship remained fragmented; and map research domains relevant to social, behavioral, public safety, and human services scholarship. The review used a structured, comprehensive literature review strategy supported by integrative synthesis procedures. The final corpus contained 34 scholarly sources, including 32 …

With Students, As A Student: Using Reflexive Autoethnography To Make Sense Of Navigating Student–Researcher Liminality In A Ph.D., Melody Bishop Aug 2026

With Students, As A Student: Using Reflexive Autoethnography To Make Sense Of Navigating Student–Researcher Liminality In A Ph.D., Melody Bishop

The Qualitative Report

Postgraduate researchers (PGRs) are increasingly encouraged to practice reflexivity. But there is a lack of PGR-authored literature about what it means to negotiate multiple identities, particularly for student–researchers doing research with students. This paper explores challenges experienced during a longitudinal Ph.D. project involving undergraduate students with long-term health conditions. I present outcomes of a reflexive autoethnographic analysis of a diary kept making sense of research challenges, including holding dual positions as a student–researcher at the same institution. Drawing on the notion of liminality, I argue that the boundaries between my student–researcher identities, and between myself and participants, have been consistently …
