Exploring anti-gang advertising: Focus group discussions with gang members and at-risk youth

The use of advertising to discourage gang membership is a issue that has been heavily debated, but the controversy has continually overlooked the children for whom the ads are intended to help. The purpose of this thesis is to explore the use of anti-gang advertising by seeking the opinions of young people living in a gang environment. The results of this study provide a detailed account of discussions about anti-gang messages generated from focus groups with gang members and at-risk youth and suggest two main contributions that anti-gang advertising can make to larger gang reform efforts. In addition, the conclusions offer insight into how gang members and at-risk youth perceive themselves and their environment and how others can effectively communicate with them

Post a Comment Below: Aesthetics and Authenticity in the YouTube Hijabi Community

Islam has become one of the fastest growing religions in the U.S., particularly among young white women. As these women have turned to online media for information about Islam, a burgeoning community has emerged, specifically on YouTube. This study analyzes elements of this community: the aesthetics of the videos, the women who are creating the videos, the narratives within the videos, and the interactions that occur in the comment sections. These videos are about more than just sharing a conversion narrative, but also the women in the videos are able to embody Islamic material forms and to visually represent themselves as Muslim. The viewers can post comments that reinforce this Islamic identity. While the religious subject is still constituted through material forms and discourse, the affordances of the YouTube medium, particularly the aesthetic style and authentic interactions, allow for the video-maker to represent herself as a Muslim

Voiceless Icons No More: the Self-Representations of Muslim American Lives in Digital Media

With the proposed travel bans in the U.S., niqab bans in Canadian cities, fears over terrorism, attacks on veiled women, and concerns about refugees, Muslim Americans have become prominent icons of larger political issues in North American society. While the images of Muslims have dominated public spaces, the complex lives and significant concerns of Muslim Americans have often gone untold. This study focuses on the creative work that Muslim American youth are producing and circulating through digital media spaces and mobile technologies. The projects discussed in this study include: the Places You’ll Pray photo series, which documents public prayer locations; the visual representation of the Salafi Feminist blogger; a collection of self-portraits from women who wear the niqab face veil; the artistic projects created in response to the murder of three Muslim college students in Chapel Hill, NC; and the Mipsterz Islamic fashion video. Through an analysis of these cases, this dissertation examines how Muslim American youth create innovative projects that engage with aesthetic styles and affects to shift assumptions about their lives and dis-articulate the feelings of foreignness and fear that often adhere to their bodies. These projects are an effort for Muslims, who have been marginalized from traditional political spaces, to assert the equality and value of their lives. Without over-idealizing the progressive potential of emerging media spaces, this study examines how digital media provide the flexible space and creative tools to produce and circulate these representations. Using digital media to create and distribute artistic projects is not political activism in and of itself, but rather it serves as a way for Muslim youth to formulate and articulate their own subjectivity as political actors and to connect with others in preparation for wider social action. Through this creative work, Muslim youth acquire a sense of their agency and ability to intercede in political spaces. Furthermore, these Muslim creators are not trying to assimilate into an American way of life, but rather assert that they can determine for themselves how they will be Muslim and American, along with numerous other markers

Parentage of Hydatidiform Moles

We were presented with the STR (short tandem repeat) profiles from two separate paternity trios. Each trio consisted of a mother, an alleged father, and products of conception (POC) that contained a hydatidiform mole but no visible fetus. In both cases, antecedent pregnancies had followed alleged sexual assaults. Mole classification and pathogenesis are described in order to explain the analyses and statistical reasoning used in each case. One mole exhibited several loci with two different paternal alleles, indicating it was a dispermic (heterozygous) mole. Maternal decidua contaminated the POC, preventing the identification of paternal obligate alleles (POAs) at some loci. The other mole exhibited only one paternal allele/locus at all loci and no maternal alleles, indicating it was a diandric and diploid (homozygous) mole. In each case, traditional calculations were used to determine paternity indices (PIs) at loci that exhibited one paternal allele/locus. PIs at mole loci with two different paternal alleles/locus were calculated from formulas first used for child chimeras that are always dispermic. Combined paternity indices in both mole cases strongly supported the paternity of each suspect.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/155886/1/jfo14291.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/155886/2/jfo14291_am.pd

Lack of neuroinflammation in the HIV-1 transgenic rat: An [18 F]-DPA714 PET imaging study

BACKGROUND: HIV-associated neuroinflammation is believed to be a major contributing factor in the development of HIV-associated neurocognitive disorders (HAND). In this study, we used micropositron emission tomography (PET) imaging to quantify neuroinflammation in HIV-1 transgenic rat (Tg), a small animal model of HIV, known to develop neurological and behavioral problems. METHODS: Dynamic [(18)F]DPA-714 PET imaging was performed in Tg and age-matched wild-type (WT) rats in three age groups: 3-, 9-, and 16-month-old animals. As a positive control for neuroinflammation, we performed unilateral intrastriatal injection of quinolinic acid (QA) in a separate group of WT rats. To confirm our findings, we performed multiplex immunofluorescent staining for Iba1 and we measured cytokine/chemokine levels in brain lysates of Tg and WT rats at different ages. RESULTS: [(18)F]DPA-714 uptake in HIV-1 Tg rat brains was generally higher than in age-matched WT rats but this was not statistically significant in any age group. [(18)F]DPA-714 uptake in the QA-lesioned rats was significantly higher ipsilateral to the lesion compared to contralateral side indicating neuroinflammatory changes. Iba1 immunofluorescence showed no significant differences in microglial activation between the Tg and WT rats, while the QA-lesioned rats showed significant activation. Finally, cytokine/chemokine levels in brain lysates of the Tg rats and WT rats were not significantly different. CONCLUSION: Microglial activation might not be the primary mechanism for neuropathology in the HIV-1 Tg rats. Although [(18)F]DPA-714 is a good biomarker of neuroinflammation, it cannot be reliably used as an in vivo biomarker of neurodegeneration in the HIV-1 Tg rat.

International variation in invasive care of the elderly with acute coronary syndromes

Aims To explore variations in invasive care of the elderly with acute coronary syndromes across international practice. Methods and results Using combined populations from the SYMPHONY and 2nd SYMPHONY trials, we describe 30-day cardiac catheterization in elderly (≥75 years; n=1794) vs. younger patients (<75 years; n=14 043) after multivariable adjustment and by region of enrolment. The use of cardiac catheterization and revascularization were not protocol-specified. Elderly patients (median age 78 years) were more often female and more frequently had hypertension, diabetes, prior myocardial infarction, and prior coronary bypass surgery. Overall, they underwent less cardiac catheterization than younger patients [53 vs. 63%; adjusted OR 0.53 (0.46, 0.60)]. The absolute rate of cardiac catheterization in the elderly varied from 77% (vs. 91% in younger patients) in the US cohort to 27% (vs. 41% in younger patients) in the non-US cohort. Revascularization of elderly who underwent cardiac catheterization was also higher in US than non-US cohorts (71.3 vs. 53.6%). There was a significant interaction between the patient age and the use of catheterization across US and non-US regions of enrolment, as well as differences in the predictors of catheterization in the elderly. Despite these findings, after adjustment, 90-day rates of death and death or myocardial infarction (MI) were not significantly different in elderly who underwent catheterization compared with those who did not. Conclusion Although older age is universally predictive of lower use of cardiac catheterization, marked variation in catheterization of the elderly exists across international practice. Demonstrated differences in patterns of use suggest a lack of consensus regarding optimal use of an invasive strategy in the elderl

Local recurrence after surgery for non–small cell lung cancer: A recursive partitioning analysis of multi-institutional data

OBJECTIVE: To define subgroups at high risk of local recurrence (LR) after surgery for non-small cell lung cancer using a recursive partitioning analysis (RPA). METHODS: This Institutional Review Board-approved study included patients who underwent upfront surgery for I-IIIA non-small cell lung cancer at Duke Cancer Institute (primary set) or at other participating institutions (validation set). The 2 data sets were analyzed separately and identically. Disease recurrence at the surgical margin, ipsilateral hilum, and/or mediastinum was considered an LR. Recursive partitioning was used to build regression trees for the prediction of local recurrence-free survival (LRFS) from standard clinical and pathological factors. LRFS distributions were estimated with the Kaplan-Meier method. RESULTS: The 1411 patients in the primary set had a 5-year LRFS rate of 77% (95% confidence interval [CI], 0.74-0.81), and the 889 patients in the validation set had a 5-year LRFS rate of 76% (95% CI, 0.72-0.80). The RPA of the primary data set identified 3 terminal nodes based on stage and histology. These nodes and their 5-year LRFS rates were as follows: (1) stage I/adenocarcinoma, 87% (95% CI, 0.83-0.90); (2) stage I/squamous or large cell, 72% (95% CI, 0.65-0.79); and (3) stage II-IIIA, 62% (95% CI, 0.55-0.69). The validation RPA identified 3 terminal nodes based on lymphovascular invasion (LVI) and stage: (1) no LVI/stage IA, 82% (95% CI, 0.76-0.88); (2) no LVI/stage IB-IIIA, 73% (95% CI, 0.69-0.80); and (3) LVI, 58% (95% CI, 0.47-0.69). CONCLUSIONS: The risk of LR was similar in the primary and validation patient data sets. There was discordance between the 2 data sets regarding the clinical factors that best segregate patients into risk groups

Multi-site investigation of strategies for the implementation of CYP2C19 genotype-guided antiplatelet therapy

CYP2C19 genotype-guided antiplatelet therapy following percutaneous coronary intervention is increasingly implemented in clinical practice. However, challenges such as selecting a testing platform, communicating test results, building clinical decision support processes, providing patient and provider education, and integrating methods to support the translation of emerging evidence to clinical practice are barriers to broad adoption. In this report, we compare and contrast implementation strategies of 12 early adopters, describing solutions to common problems and initial performance metrics for each program. Key differences between programs included the test result turnaround time and timing of therapy changes which are both related to CYP2C19 testing model and platform used. Sites reported the need for new informatics infrastructure, expert clinicians such as pharmacists to interpret results, physician champions, and ongoing education. Consensus lessons learned are presented to provide a path forward for those seeking to implement similar clinical pharmacogenomics programs within their institutions.
