Rap Music Literacy: A Case Study of Millennial Audience Reception to Rap Lyrics Depicting Independent Women

Using a feminist lens and a constructivist approach as the theoretical framework, we used rap lyrics and videos to help college students explore mass media’s representation of the “independent” Black woman and the concept of “independence” in general. Students must be able to formulate their own concept of independence to counteract the messages and stereotypes they receive in popular culture through advertisements, film, print and music. The authors found that independence is situationally defined and it is a complex concept that is differentiated in consideration of age, race, and gender. Participants noted that rap music has the potential to influence their definitions and perceptions of rap music. More educational opportunities are needed where students can utilize constructivist pedagogies in order to become more critically aware of the influence of the media and systems of social stratification

Engaging in “dangerous discussions”: Fostering cultural competence through the analysis of depictions of college life in popular films.

This qualitative case study utilized critical media literacy to guide the analysis of the depiction of racially and ethnically diverse college students in contemporary popular films. Participants in this study were racially and ethnically diverse undergraduate students enrolled at a private, predominantly White institution in the United States. Three primary themes emerged from this study. First, students of color were more apt to recognize stereotypical portrayals of people of color in the films, whereas White students’ responses were more attuned with color-blind racial ideology (CBRI). Second, media-centered discussions provided an outlet for students of color to share their personal experiences with racism, stereotyping, and prejudice. In doing so, students of color seek to build the cultural competence of peers who may hold CBRI beliefs. Finally, this study presents a need for critical media literacy. Regardless of race and/or ethnicity, the undergraduates who participated in our study communicated an importance of examining media messages, such as stereotypes of people of color, from a critical perspective. For college and university administrators, such as chief diversity officers, this study is significant in presenting a means for engaging students, faculty, and other stakeholders in dialogue about racial issues in the hopes of fostering a more welcoming campus racial climate for students of color

Critical Mirrors: Diverse College Students\u27 Perspectives on Stereotypes Depicted in Popular Films About College Life

This qualitative study explored diverse college students’ perspectives on the portrayal of college life in recent popular films. Results from this study suggest that White college students dismiss stereotypes as comedic satire whereas their non-White peers readily identify the influence of negative media representations upon their academic and ethnic identities. These findings exemplify the need to promote positive representations of college students from racially and culturally diverse backgrounds. Findings suggest the need for Critical Media Literacy education to help young adults dismantle stereotypes in mainstream society while developing cultural competence

Drivers of understory plant communities in Sierra Nevada mixed conifer forests with pyrodiversity

Background: Fire suppression in western North America increased and homogenized overstory cover in conifer forests, which likely affected understory plant communities. We sought to characterize understory plant communities and their drivers using plot-based observations from two contemporary reference sites in the Sierra Nevada, USA. These sites had long-established natural fire programs, which have resulted in restored natural fire regimes. In this study, we investigated how pyrodiversity—the diversity of fire size, severity, season, and frequency—and other environment factors influenced species composition and cover of forest understory plant communities. Results: Understory plant communities were influenced by a combination of environmental, plot-scale recent fire history, and plot-neighborhood pyrodiversity within 50 m. Canopy cover was inversely proportional to understory plant cover, Simpson’s diversity, and evenness. Species richness was strongly influenced by the interaction of plot-based fire experience and plot-neighborhood pyrodiversity within 50 m. Conclusions: Pyrodiversity appears to contribute both directly and indirectly to diverse understory plant communities in Sierra Nevada mixed conifer forests. The indirect influence is mediated through variability in tree canopy cover, which is partially related to variation in fire severity, while direct influence is an interaction between local and neighborhood fire activity

Atomic-scale Studies of Uranium Oxidation and Corrosion by Water Vapour

Understanding the corrosion of uranium is important for its safe, long-term storage. Uranium metal corrodes rapidly in air, but the exact mechanism remains subject to debate. Atom Probe Tomography was used to investigate the surface microstructure of metallic depleted uranium specimens following polishing and exposure to moist air. A complex, corrugated metal-oxide interface was observed, with approximately 60 at.% oxygen content within the oxide. Interestingly, a very thin (~5 nm) interfacial layer of uranium hydride was observed at the oxide-metal interface. Exposure to deuterated water vapour produced an equivalent deuteride signal at the metal-oxide interface, confirming the hydride as originating via the water vapour oxidation mechanism. Hydroxide ions were detected uniformly throughout the oxide, yet showed reduced prominence at the metal interface. These results support a proposed mechanism for the oxidation of uranium in water vapour environments where the transport of hydroxyl species and the formation of hydride are key to understanding the observed behaviour

GED: the method for group evolution discovery in social networks

The continuous interest in the social network area contributes to the fast development of this field. The new possibilities of obtaining and storing data facilitate deeper analysis of the entire network, extracted social groups and single individuals as well. One of the most interesting research topic is the dynamics of social groups, it means analysis of group evolution over time. Having appropriate knowledge and methods for dynamic analysis, one may attempt to predict the future of the group, and then manage it properly in order to achieve or change this predicted future according to specific needs. Such ability would be a powerful tool in the hands of human resource managers, personnel recruitment, marketing, etc. The social group evolution consists of individual events and seven types of such changes have been identified in the paper: continuing, shrinking, growing, splitting, merging, dissolving and forming. To enable the analysis of group evolution a change indicator - inclusion measure was proposed. It has been used in a new method for exploring the evolution of social groups, called Group Evolution Discovery (GED). The experimental results of its use together with the comparison to two well-known algorithms in terms of accuracy, execution time, flexibility and ease of implementation are also described in the paper.Comment: 14 pages, Social Network Analysis and Minin

Trion formation dynamics in monolayer transition metal dichalcogenides

We report charged exciton (trion) formation dynamics in doped monolayer transition metal dichalcogenides, specifically molybdenum diselenide (MoSe2), using resonant two-color pump-probe spectroscopy. When resonantly pumping the exciton transition, trions are generated on a picosecond time scale through exciton-electron interaction. As the pump energy is tuned from the high energy to low energy side of the inhomogeneously broadened exciton resonance, the trion formation time increases by ∼50%. This feature can be explained by the existence of both localized and delocalized excitons in a disordered potential and suggests the existence of an exciton mobility edge in transition metal dichalcogenides

Process evaluation of appreciative inquiry to translate pain management evidence into pediatric nursing practice

Background Appreciative inquiry (AI) is an innovative knowledge translation (KT) intervention that is compatible with the Promoting Action on Research in Health Services (PARiHS) framework. This study explored the innovative use of AI as a theoretically based KT intervention applied to a clinical issue in an inpatient pediatric care setting. The implementation of AI was explored in terms of its acceptability, fidelity, and feasibility as a KT intervention in pain management. Methods A mixed-methods case study design was used. The case was a surgical unit in a pediatric academic-affiliated hospital. The sample consisted of nurses in leadership positions and staff nurses interested in the study. Data on the AI intervention implementation were collected by digitally recording the AI sessions, maintaining logs, and conducting individual semistructured interviews. Data were analysed using qualitative and quantitative content analyses and descriptive statistics. Findings were triangulated in the discussion. Results Three nurse leaders and nine staff members participated in the study. Participants were generally satisfied with the intervention, which consisted of four 3-hour, interactive AI sessions delivered over two weeks to promote change based on positive examples of pain management in the unit and staff implementation of an action plan. The AI sessions were delivered with high fidelity and 11 of 12 participants attended all four sessions, where they developed an action plan to enhance evidence-based pain assessment documentation. Participants labeled AI a 'refreshing approach to change' because it was positive, democratic, and built on existing practices. Several barriers affected their implementation of the action plan, including a context of change overload, logistics, busyness, and a lack of organised follow-up. Conclusions Results of this case study supported the acceptability, fidelity, and feasibility of AI as a KT intervention in pain management. The AI intervention requires minor refinements (e.g., incorporating continued follow-up meetings) to enhance its clinical utility and sustainability. The implementation process and effectiveness of the modified AI intervention require evaluation in a larger multisite study
