Mapping Religious Sites In China: A Research Note, Jackie Henke, Fenggang Yang Jan 2022

Mapping Religious Sites In China: A Research Note, Jackie Henke, Fenggang Yang

Department of Sociology Faculty Publications

Drawing from visual studies scholarship, we highlight current and persistent critiques of sociological visualization, note recent developments in visualization tools for sociologists, and propose how sociologists can be reflective about their visualization choices. As a case study, we outline the visualization development and selection process in our project of mapping Chinese religious venues. We explain the visualization challenges we faced, the visual biases we hoped to manage, the strengths and limitations of various visualization methods we identified, and how we selected visualizations for varying research queries. In addition, we provide a list of considerations for fellow sociologists working to visualize …


Phonetic Feature Size In Second Language Acquisition: Examining Vot In Voiceless And Voiced Stops, Daniel J. Olson Jan 2022

Phonetic Feature Size In Second Language Acquisition: Examining Vot In Voiceless And Voiced Stops, Daniel J. Olson

School of Languages and Cultures Faculty Publications

Featural approaches to second language phonetic acquisition posit that the development of new phonetic norms relies on sub-phonemic features, expressed through a constellation of articulatory gestures and their corresponding acoustic cues, which may be shared across multiple phonemes. Within featural approaches, largely supported by research in speech perception, debate remains as to the fundamental scope or “size” of featural units. The current study examines potential featural relationships between voiceless and voiced stop consonants, as expressed through the voice onset time cue. Native English-speaking learners of Spanish received targeted training on Spanish voiceless stop consonant production through a visual feedback paradigm. …
