ZnO with wurtzite structure was present in the mixed oxide as corroborated by Raman spectroscopy and X-ray diffraction analysis. All the samples showed nanorod morphological features. The presence of Ru6+/Ru4+ couples on ZnO modified the band gap of the mixed oxides and led to a shift of the band gap energy from 3.20 eV to 3.07 eV. Ru addition increased the surface area and significantly promoted the formation of active surface oxygen species such as hydroradicals evidenced by the fluorescence spectroscopy measurement. In the photodegradation of 4-chlorophenol solution under UV irradiation, a notable increase in photoactivity was obtained as the amount of RuO2 in the mixed oxides increased to 3 wt%. The charge transfer between Ru6+/Ru4+ couples and ZnO nanoparticles together with the formation...

Cellular phones offer a low-cost method of reaching larger populations and have the potential for increased tailoring and interactivity. This supports the development of mHealth interventions to address healthcare disparities in this population. In this study we sought to evaluate the feasibility and acceptability of interactive Spanishlanguage text messages sent throughout a child's first year of life in a low-income, limited-English proficient (LEP) Latino population to support families in accessing and using pediatric primary care more effectively. Methods: Participants (n=79) received interactive text messages over a period of 12 months as a part of a multi-modal mHealth intervention conducted at an urban academic pediatric primary care practice. Inclusion criteria were: singleton infant <2 months of age, enrollment in public health insurance, parent age >18, parent preferred healthcare language of Spanish, and at least one household cellular phone. Interactive text messages were designed to promote increased healthcare engagement and prompted participant responses through preprogramed algorithms. Text message sequences included clinic appointment reminders, support for obtaining medicine and completing referral appointments, monitoring of illness care needs and use, and parent support program reminders. Descriptive analyses were used to examine text message volume, usability, and participant response to text sequences. Results: Among participants, mean parent age was 30.1 years (SD: 6.1 years); mean years in the US was 7.5 years (SD: 5.1 years). 63.3% of parents had less than a high school education and 84.8% of parents had possible/high likelihood of limited health literacy. Participants completed the majority of sequences with appointment reminder sequences having the quickest response time. The top quartile of responders completed 88.3% of sequences; lower educational attainment was associated with lower text message sequence completion. Participants rated the program positively, especially the appointment reminders. Conclusions: LEP Latino parents successfully engaged with interactive Spanish-language text sequences and parent acceptability was high. This study demonstrates feasibility for interventions employing this technology. Text message interventions may be a feasible approach to reduce healthcare disparities and costs for vulnerable populations.

The Trace of a Mark That Scatters: The Anthropoi and the Rhetoric of Decoloniality

Critics have drawn from Latinamericanist theories of decoloniality to mobilize epistemological alternatives to Western forms of knowledge production and to critique the representations of alterity in the Western rhetorical tradition, posing variations of a common question: how to proceed from merely tolerating difference in the Western paradigm of rhetoric to actually theorizing rhetoric from the locus of non-Western (that is, non-logocentric) space? In this essay, we analyze the aporia dredged up by Latinamericanist theories of decoloniality as a prism through which to renew and rethink the terms and conditions of comparativist inquiry. We conclude by setting to work on preparing the non-nostalgic grounds for an alterity yet to arrive under the heading of the X.

We evaluated a nine-minute educational video supporting healthcare navigation and engagement skills of Spanish-speaking Latino parents of infants. Participants viewed the video at their child’s 2-month well-visit, completed a pre-and post-video knowledge evaluation, and answered open-ended questions on video style. A paired t test was used to examine differences in knowledge and open-ended responses were coded using an iterative, consensus-based process. Of the 79 participants, 63.3% had an education level below high school diploma/GED and 84.8% were at risk for limited health literacy. There was a significant gain in healthcare navigation and engagement knowledge after watching the video (p < 0.001). Parents expressed that the video was interesting and provided useful information. Parents valued the knowledge gained and preferred videos over written materials for receiving culturally and linguistically tailored health education.
