Dark Tourism And ‘Partial Religiosity’: Ontological-Aesthetic Pilgrimage In Camiguin Island, Philippines, Jan Gresil Kahambing

International Journal of Religious Tourism and Pilgrimage

This paper theorizes the contrast between dark tourism and what is referred to as ‘partial religiosity’ in the context of travel to selected tourist destinations on Camiguin Island, Philippines. Also called ‘thanatourism’, dark tourism is about visiting places that challenge the value derived from the association with death either from tragedies of naturally occurring catastrophes (such as earthquakes, volcanic eruptions, or typhoons) or disasters produced by humans (such as genocides and violations of human rights). Focus is on three spots that sufficiently fit the description of dark tourist sites in Camiguin in the sense of naturally-caused disasters, namely: the Sunken …

Police Reform Advocacy And The Emergence Of The Seattle Black Panthers, Hayden Young

Lawrence University Honors Projects

This honors project examines the factors which led to the emergence of the Seattle chapter of the Black Panther Party (BPP) in 1968, with a focus on one of the BPP’s signature issues — police reform. Negative perceptions of the Seattle PD, especially among the city’s rapidly growing population of Black residents, led Mayor Allan Pomeroy to form a citizen’s committee titled “the Mayor’s Advisory Committee on Police Practices” (MACPP) in 1955. The MACPP recommended the formation of a civilian-led police oversight board in its 1956 final report, and civil rights groups such as the Urban League, ACLU, and NAACP …

Neural Oscillations Enable Concurrent Visual Perception And Visual Working Memory Processing, Khayla Santiago

Lawrence University Honors Projects

Successful goal-directed behavior requires balancing task-relevant information stored in working memory and the continuous processing of incoming sensory input, yet the neural mechanisms underlying this coordination remain unclear. This study examines how neural oscillations support concurrent visual perception and visual working memory. Using electroencephalography (EEG), we recorded brain activity while participants performed a dual task paradigm requiring them to simultaneously maintain one orientation in their memory while monitoring another orientation on the screen. After variable time intervals (50 different SOAs between 500-1500ms), participants compared a probe against either the memorized or visually monitored orientation. Analysis of response times and accuracy …

Predicting The Photophysics Of Bdpa-Based Radicals Using Density Functional Theory, Samantha Kristine Piwoni

Lawrence University Honors Projects

Through this project, computational tools were refined to be more rigorous and robust for the primarily synthetic SazLab at Lawrence University. The primary research of the SazLab involves synthesizing and characterizing luminescent radicals based on two stable radical systems: TTM and BDPA. The BDPA system is of particular interest because the effects on luminescence of its nonalternant symmetry are less understood compared to the alternant symmetry of TTM. Quantum mechanical calculations, particularly Density Functional Theory, were utilized to help target syntheses and gain insight into the photophysics of luminescence. A prior student researcher with the SazLab had successfully synthesized 2-pyBDPA, …

“Why Us, Though?” Gendered Resilience In Climate-Displaced Bangladesh Narrated By Child Brides, Marzuka Amal Binthe Akber

Lawrence University Honors Projects

This thesis explores the resilience strategies narrated by women and girls displaced by climate change and subjected to child marriage in Bangladesh. Centering their voices and lived experiences, it highlights the intricate, often invisible methods through which these women navigate the intersectional precarity of environmental displacement, gender norms, and socio-economic marginalization. Through qualitative fieldwork conducted in riverine islands (chars), urban informal settlements, and government resettlement sites, the study foregrounds community practices like adda (social storytelling), mutual caregiving, informal healthcare, bodily negotiations, and strategic silence. Challenging dominant narratives of passive victimhood, it reveals resilience as relational, iterative, and context-specific acts rooted …
