The influence of family and culture on South Asian student dating violence survivors' college experiences.

Objective: This paper discusses the influence of family and cultural backgrounds on South Asian student survivors' understandings of dating relationships and help-seeking after experiencing dating violence. Methods: Six South Asian undergraduate women dating violence survivors participated in two thé talks (similar to semi structured interviews) and a photo-elicitation activity to share their experiences of dating violence and how they make meaning of these experiences. Findings: Through analysis guided by the tenets of Bhattacharya's Par/Des(i) framework, this paper highlights two key findings: 1) the powerful role of cultural values in students' conceptualizations of healthy and unhealthy relationships; and 2) the effect of familial and intergenerational experiences on students' help-seeking behaviors. Conclusion: Findings highlight the need to incorporate considerations of family and culture in efforts to address and prevent dating violence in higher education.

Women of Color Student Survivors' Perceptions of Campus Sexual Assault Prevention Programming.

This article presents a qualitative study of 44 Women of Color undergraduate student survivors' perceptions of campus sexual assault prevention programming using the framework of standpoint theory. Participants held perceptions concerning online training prior to college, the in-person presentations they attended during new student orientation, and the lack of information relayed through prevention programs about sexual assault perpetration. Findings highlight the need for continued research investigating the standpoints of Women of Color students to better inform implementation of prevention efforts.

Silver nanowire exposure results in internalization and toxicity to Daphnia magna.

Nanowires (NWs), high-aspect-ratio nanomaterials, are increasingly used in technological materials and consumer products and may have toxicological characteristics distinct from nanoparticles. We carried out a comprehensive evaluation of the physicochemical stability of four silver nanowires (AgNWs) of two sizes and coatings and their toxicity to Daphnia magna . Inorganic aluminum-doped silica coatings were less effective than organic poly(vinyl pyrrolidone) coatings at preventing silver oxidation or Ag(+) release and underwent a significant morphological transformation within 1 h following addition to low ionic strength Daphnia growth media. All AgNWs were highly toxic to D. magna but less toxic than ionic silver. Toxicity varied as a function of AgNW dimension, coating, and solution chemistry. Ag(+) release in the media could not account for observed AgNW toxicity. Single-particle inductively coupled plasma mass spectrometry distinguished and quantified dissolved and nanoparticulate silver in microliter-scale volumes of Daphnia magna hemolymph with a limit of detection of approximately 10 ppb. The silver levels within the hemolymph of Daphnia exposed to both Ag(+) and AgNW met or exceeded the initial concentration in the growth medium, indicating effective accumulation during filter feeding. Silver-rich particles were the predominant form of silver in hemolymph following exposure to both AgNWs and Ag(+). Scanning electron microscopy imaging of dried hemolymph found both AgNWs and silver precipitates that were not present in the AgNW stock or the growth medium. Both organic and inorganic coatings on the AgNW were transformed during ingestion or absorption. Pathway, gene ontology, and clustering analyses of gene expression response indicated effects of AgNWs distinct from ionic silver on Daphnia magna .
