Linking health education, civic engagement, and research at a large Federally Qualified Health Center to address health disparities.

OBJECTIVE: To develop a framework for patient-centered research in a community health center. STUDY SETTING: Primary organizational case-study data were collected at a large Federally Qualified Health Center (FQHC) in Southern California from 2019 to 2021. STUDY DESIGN: Thirty stakeholders, including patients, community leaders, students, medical providers, and academic partners, participated in community-engagement capacity-building exercises and planning. These activities were guided by Community Based Participatory Principles and were part of an initiative to address health disparities by supporting patient and community-engaged research. DATA COLLECTION: The study included an iterative development process. Stakeholders participated in a total of 44 workgroup meetings and 7 full-group quarterly convenings. The minutes of the meetings from both workgroups and quarterly convenings were used to document the evolution of the initiative. PRINCIPLE FINDINGS: Stakeholders concluded that health equity research needs to be part of a larger engagement ecosystem and that, in some ways, engagement on research projects may be a later-stage form of engagement following patient/community and staff/researcher coeducation and cocapacity building efforts. CONCLUSIONS: Community health center stakeholders viewed successful engagement of community members in patient-centered health equity research as involving a web of longitudinal, evolving internal and external relationships rather than discrete, time-limited, and single-project-based dyadic connections.

Broken Rotor Bar Detection in Induction Motors through Contrast Estimation.

Induction motors (IM) are key components of any industrial process; hence, it is important to carry out continuous monitoring to detect incipient faults in them in order to avoid interruptions on production lines. Broken rotor bars (BRBs), which are among the most regular and most complex to detect faults, have attracted the attention of many researchers, who are searching for reliable methods to recognize this condition with high certainty. Most proposed techniques in the literature are applied during the IM startup transient, making it necessary to develop more efficient fault detection techniques able to carry out fault identification during the IM steady state. In this work, a novel methodology based on motor current signal analysis and contrast estimation is introduced for BRB detection. It is worth noting that contrast has mainly been used in image processing for analyzing texture, and, to the best of the authors' knowledge, it has never been used for diagnosing the operative condition of an induction motor. Experimental results from applying the approach put forward validate Unser and Tamura contrast definitions as useful indicators for identifying and classifying an IM operational condition as healthy, one broken bar (1BB), or two broken bars (2BB), with high certainty during its steady state.

Exposure to tobacco marketing in bars predicts subsequent use of multiple tobacco products among non-tobacco-using college students.

BACKGROUND: Due to other marketing restrictions, one venue where tobacco companies concentrate their marketing efforts to reach young adults is bars/nightclubs. OBJECTIVE: This study examined the relationship between exposure to tobacco marketing in bars/nightclubs and number of alternative tobacco/nicotine products used 6 months later among college students. METHODS: Participants were 1,406 students aged 18-29 years old who reported going to bars or nightclubs at least rarely (M age=21.95; 67% female; 46% non-Hispanic white). Students completed an online survey in fall 2014/spring 2015 (wave 1) and again 6 months later (wave 2). Multilevel Poisson regression models were used to assess the relationship between exposure to three types of marketing at bars/nightclubs at wave 1 (tobacco/nicotine product advertisements; free samples; industry representatives) and number of tobacco products used (range=0-5) at wave 2, controlling for school type (2 year vs 4 year), age, sex, race/ethnicity and frequency of bar visits. An interaction between the number of wave 1 products and each marketing variable was tested. RESULTS: Greater exposure to free samples and tobacco industry representatives at bars/nightclubs predicted a greater number of products used 6 months later, but only among wave 1 non-tobacco users and not among tobacco users. Exposure to advertisements at bars/nightclubs did not predict the number of products used 6 months later. CONCLUSION: Tobacco companies claim that marketing is targeted to those who already use the product, not to non-users. However, the current study indicates tobacco marketing in bars and nightclubs may encourage use among non-users and has no influence on current users.

Exposure to tobacco and nicotine product advertising: Associations with perceived prevalence of use among college students.

OBJECTIVE: The purpose of this study was to examine the relationship between exposure to tobacco marketing and perceptions of peer tobacco use among college students. PARTICIPANTS: Participants were 5,767 undergraduate students from 19 colleges/universities in the State of Texas. METHODS: Students completed an online survey, in the spring of 2016, that assessed past 30 day exposure to e-cigarette, cigar, smokeless tobacco, and traditional cigarette advertising across multiple marketing channels, past 30 day use of each product, and perceived prevalence of peer use. Multi-level linear regression models were run to examine the associations between exposure to tobacco advertising and perceptions of peer tobacco use controlling for age, gender, race/ethnicity, use and school. RESULTS: Greater exposure to advertising was associated with greater perceived prevalence of peer use. CONCLUSIONS: Given the normative effects of advertising on perceived peer tobacco use, college tobacco initiatives should include descriptive norms education to counteract inaccurate perceptions.
