Meeting in the middle: Fred L. Casmir\u27s contributions to the field of intercultural communication

Fred Casmir\u27s third culture building (TCB) framework made a major theoretical contribution to communication studies. Casmir conceptualized the framework as an active process whereby different cultural groups come together to form a third culture between them. The third culture then becomes a common ground for all participants; a cognitive space that incorporates elements of both cultures and yet remains separate and distinct. Third culture building is a departure from adoption (the process of taking on the cultural mores of another) or adaptation (modifying one\u27s cultural mores to better fit those of another), and achieved through deliberate development in an extended process, during which all participants gain an understanding of, and appreciation for, one another. In this essay, the authors review the life and work of Fred Casmir – a leading figure in establishing intercultural communication as a specific area of study. Next the authors discuss the ideological foundations, intended use, key applications and heuristic value of Casmir\u27s third culture building framework

Too Big Too Fast? Potential Implications of the Rapid Increase in Emergency Medicine Residency Positions

Emergency medicine (EM) has expanded rapidly since its inception in 1979. Workforce projections from current data demonstrate a rapid rise in the number of accredited EM residency programs and trainee positions. Based on these trends, the specialty may soon reach a point of saturation, particularly in urban areas. This could negatively impact future trainees entering the job market as well as the career plans of medical students. More time and resources should be devoted to obtaining accurate projections, assessing the distribution of emergency physicians in rural versus urban settings, and implementing central workforce planning to protect the future of graduating trainees.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154425/1/aet210400.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154425/2/aet210400_am.pd

Open ventral hernia repair with a composite ventral patch : final results of a multicenter prospective study

Background: This study assessed clinical outcomes, including safety and recurrence, from the two-year follow-up of patients who underwent open ventral primary hernia repair with the use of the Parietex (TM) Composite Ventral Patch (PCO-VP). Methods: A prospective single-arm, multicenter study of 126 patients undergoing open ventral hernia repair for umbilical and epigastric hernias with the PCO-VP was performed. Results: One hundred twenty-six subjects (110 with umbilical hernia and 16 with epigastric hernia) with a mean hernia diameter of 1.8cm (0.4-4.0) were treated with PCO-VP. One hundred subjects completed the two-year study. Cumulative hernia recurrence was 3.0% (3/101; 95%CI: 0.0-6.3%) within 24months. Median Numeric Rating Scale pain scores improved from 2 [0-10] at baseline to 0 [0-3] at 1 month (P<0.001) and remained low at 24months 0 [0-6] (P<0.001). 99% (102/103) of the patients were satisfied with their repair at 24months postoperative. Conclusions: The use of PCO-VP to repair primary umbilical and epigastric defects yielded a low recurrence rate, low postoperative and chronic pain, and high satisfaction ratings, confirming that PCO-VP is effective for small ventral hernia repair in the two-year term after implantation. Trial registration: The study was registered publically at clinicaltrials.gov (NCT01848184 registered May 7, 2013)

Marketing a tourism industry in late stage decline: The case of the Isle of Man

Qualitative interviews in the Isle of Man uncovered local perceptions of a tourism industry in late stage decline. Social impacts of decline are pronounced including facilities loss, cultural changes and a heightening of perceived peripherality: which taken together undermine local identity. Tourists are welcomed as they help to affirm the pride residents have in their island in creating a more active atmosphere, provide social interaction opportunities and to combat negative stereotyping. Thus findings emphasise the diverse, unique and persistent benefits of tourism in the Isle of Man, despite its decline. Destination marketing recommendations are therefore made to better address the experiences and desires of communities experiencing decline

Evaluation of Social Media Use by Emergency Medicine Residents and Faculty

Introduction Clinicians and residency programs are increasing their use of social media (SM) websites for educational and promotional uses, yet little is known about the use of these sites by residents and faculty. The objective of the study is to assess patterns of SM use for personal and professional purposes among emergency medicine (EM) residents and faculty. Methods In this multi-site study, an 18-question survey was sent by e-mail to the residents and faculty in 14 EM programs and to the Council of Emergency Medicine Residency Directors (CORD) listserv via the online tool SurveyMonkey™. We compiled descriptive statistics, including assessment with the chi-square test or Fisher’s exact test. StatsDirect software (v 2.8.0, StatsDirect, Cheshire, UK) was used for all analyses. Results We received 1,314 responses: 63% of respondents were male, 40% were <30 years of age, 39% were between the ages 31 and 40, and 21% were older than 40. The study group consisted of 772 residents and 542 faculty members (15% were program directors, 21% were assistant or associate PDs, 45% were core faculty, and 19% held other faculty positions. Forty-four percent of respondents completed residency more than 10 years ago. Residents used SM markedly more than faculty for social interactions with family and friends (83% vs 65% [p<0.0001]), entertainment (61% vs 47% [p<0.0001]), and videos (42% vs 23% [p=0.0006]). Residents used Facebook™ and YouTube™ more often than faculty (86% vs 67% [p<0.001]; 53% vs 46% [p=0.01]), whereas residents used Twitter™ (19% vs 26% [p=0.005]) and LinkedIn™ (15% vs 32% [p<0.0001]) less than faculty. Overall, residents used SM sites more than faculty, notably in daily use (30% vs 24% [p<0.001]). For professional use, residents were most interested in its use for open positions/hiring (30% vs 18% [p<0.0001]) and videos (33% vs 26% [p=0.005]) and less interested than faculty with award postings (22% vs 33% [p<0.0001]) or publications (30% vs 38% [p=0.0007]). Conclusion EM residents and faculty have different patterns and interests in the personal and professional uses of social media. Awareness of these utilization patterns could benefit future educational endeavors

The Vice Chair of Education in Emergency Medicine: A Workforce Study to Establish the Role, Clarify Responsibilities, and Plan for Success

ObjectivesDespite increasing prevalence in emergency medicine (EM), the vice chair of education (VCE) role remains ambiguous with regard to associated responsibilities and expectations. This study aimed to identify training experiences of current VCEs, clarify responsibilities, review career paths, and gather data to inform a unified job description.MethodsA 40‐item, anonymous survey was electronically sent to EM VCEs. VCEs were identified through EM chairs, residency program directors, and residency coordinators through solicitation e‐mails distributed through respective listservs. Quantitative data are reported as percentages with 95% confidence intervals and continuous variables as medians with interquartiles (IQRs). Open‐ and axial‐coding methods were used to organize qualitative data into thematic categories.ResultsForty‐seven of 59 VCEs completed the survey (79.6% response rate); 74.4% were male and 89.3% were white. Average time in the role was 3.56 years (median = 3.0 years, IQR = 4.0 years), with 74.5% serving as inaugural VCE. Many respondents held at least one additional administrative title. Most had no defined job description (68.9%) and reported no defined metrics of success (88.6%). Almost 78% received a reduction in clinical duties, with an average reduction of 27.7% protected time effort (median = 27.2%, IQR = 22.5%). Responsibilities thematically link to faculty affairs and promotion of the departmental educational mission and scholarship.ConclusionGiven the variability in expectations observed, the authors suggest the adoption of a unified VCE job description with detailed responsibilities and performance metrics to ensure success in the role. Efforts to improve the diversity of VCEs are encouraged to better match the diversity of learners.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154254/1/aet210407_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154254/2/aet210407.pd

Cytotoxicity of Atriplex confertifolia

The search for cancer treatment continues to be a global effort. As part of this global effort, many natural products have been tested against cancer cell lines, mostly from tropically located plants. This study reports that extracts of Atriplex confertifolia (Torr. and Frem.) S. Watson (Chenopodiaceae), a native North American plant (also known as shadscale or saltbush), has significant bioactivity against human breast cancer cell lines MCF-7, MDA-MB 435, MDA-MB 231, and HeLa cells (cervical cancer cells). The bioactivity of A. confertifolia extracts on these cells lines was compared to an FDA-approved cancer drug (Onxol®) and an industry-standard leukocyte control cell line. Active portions of the extracts were found primarily in the polar fractions of the plant. A dose-response curve of the extracts displayed significant cell death similar to Onxol®. The plant extracts did not significantly inhibit the viability of the leukocyte cell line. In a timed study, over 90% of cell lines MDA-MB 435 and HeLa died after 24 hours. Cell death appears to result from apoptosis
