Expectations and Experiences of African American Students at Two Predominantly White Universities in Southern Appalachia.
This study addressed the academic, cultural, and social expectations and experiences of 20 African American juniors and seniors at 2 predominantly White universities in the southern Appalachian region of the United States. The participants\u27 described experiences revealed how institutional practices promoted or obstructed their persistence to graduation.
Qualitative ethnographic methodology with critical race theory as the conceptual framework guided the study. This approach allowed for the perspectives and lived experiences of the students to be voiced and heard. Data collected included their stories based on semistructured interviews, document reviews, and observations. The constant comparison method was used to analyze the data through the critical race interpretive lens of racism as the persistent reality of people of color. In combination, the data illustrated the positive and negative impacts of student-institution relationships and the campus racial climate on African American students\u27 experiences at the universities under study.
Findings indicated a dissonance between the students\u27 academic, cultural, and social expectations and experiences primarily caused by unanticipated racist experiences in the classrooms, on the campuses, and in the campus\u27 communities-at-large. Positive relationships with administrators, faculty members, and staff emerged as the most significant contributors to the students\u27 capability to safely and successfully navigate academic, social, and cultural pathways leading to graduation. Recommendations based on the results of the study are provided for university administrators, faculty members, and staff who are committed to improving the college experience and persistence to graduation rates for students of color matriculating at predominantly White universities
Population structure of pink salmon (Oncorhynchus gorbuscha) in British Columbia and Washington, determined with microsatellites
Population structure of pink salmon (Oncorhynchus gorbuscha)
from British Columbia and Washington was examined with a survey of microsatellite variation to describe the distribution of genetic variation. Variation at 16 microsatellite loci was surveyed for approximately 46,500
pink salmon sampled from 146 locations in the odd-year broodline and from 116 locations in the even-year broodline. An index of genetic differentiation, FST, over all populations and loci in the odd-year broodline was
0.005, with individual locus values ranging from 0.002 to 0.025. Population differentiation was less in the even-year broodline, with a FST value of 0.002 over all loci, and with individual locus values ranging from 0.001 to 0.005. Greater genetic diversity was observed in the odd-year broodline. Differentiation in pink salmon allele frequencies between broodlines was approximately 5.5 times greater than regional differentiation within broodlines. A regional structuring of populations was the general pattern
observed, and a greater regional structure in the odd-year broodline than in the even-year broodline. The geographic distribution of microsatellite variation in populations of pink salmon likely ref lects a distribution of broodlines from separate refuges after the last glaciation period
MESAS: Measuring the Emission of Stellar Atmospheres at Submm/mm wavelengths
In the early stages of planet formation, small dust grains grow to become mm
sized particles in debris disks around stars. These disks can in principle be
characterized by their emission at submillimeter and millimeter wavelengths.
Determining both the occurrence and abundance of debris in unresolved
circumstellar disks of A-type main-sequence stars requires that the stellar
photospheric emission be accurately modeled. To better constrain the
photospheric emission for such systems, we present observations of Sirius A, an
A-type star with no known debris, from the JCMT, SMA, and VLA at 0.45, 0.85,
0.88, 1.3, 6.7, and 9.0 mm. We use these observations to inform a PHOENIX model
of Sirius A's atmosphere. We find the model provides a good match to these data
and can be used as a template for the submm/mm emission of other early A-type
stars where unresolved debris may be present. The observations are part of an
ongoing observational campaign entitled Measuring the Emission of Stellar
Atmospheres at Submm/mm wavelengths (MESAS)Comment: 17 pages, 1 figure, Accepted to AJ on April 25th 201
Provision and need of HIV/AIDS services in the City of Tshwane Metropolitan Municipality, 2010
Objectives. To determine the need for HIV/AIDS service provision in the City of Tshwane Metropolitan Municipality (CTMM), especially in municipal areas. Methods. The Foundation for Professional Development initiated the Compass Project. Using a questionnaire, data were collected during May - June 2010 from organisations providing HIV/AIDS services in the CTMM (organisational information and types of HIV/AIDS services). The need for HIV counselling and testing (HCT), antiretroviral treatment (ART), prevention of mother-tochild transmission (PMTCT), and care for orphans and vulnerable children (OVC) was estimated using data from various sources. Results. A total of 447 service providers was included in the study: 72.3% non-governmental organisations (NGOs); 18.1% in the public sector; 5.1% in the private sector; and 4.5% faithbased organisations. The majority of the prevention- (70.2%) and support-related services (77.4%) were provided by NGOs, while the majority of treatment-related services originated from the public sector (57.3%). Service need estimates included: HCT – 1 435 438 adults aged 15 - 49 years (11 127/service provider); total ART – 75 211 adults aged 15+ years (1 213/service provider); ART initiation – 30 713 adults aged 15+ years (495/service provider); PMTCTHCT – 30 092 pregnant women (510/service provider); PMTCTART – 7 734 HIV+ pregnant women (221/service provider); and OVC care – 54 590 children (258/service provider). Conclusions. Service gaps remain in the provision of HCT, PMTCT-ART and OVC care. ART provision must be increased, in light of new treatment guidelines from the Department of Health.S Afr Med J 2012;102:44-4
Standardization of Nomenclature in Acupuncture Research (SoNAR)
As more clinical acupuncture trials for pain are published, it becomes increasingly difficult to compare and evaluate the merits and shortcomings of such studies. A major contributory factor to this centers on the description of, and the assumptions made about, the control intervention used. In considering an acupuncture control, it is important to evaluate its physiological activity and thus far, this has not been done. A variety of different and sometimes very novel controls have been tried and used in the research setting and the inevitable consequence of this is confusion, particularly when attempting to interpret the results of trials. Researchers and other interested parties such as patients, primary care practitioners, funding agencies etc., searching for evidence in the literature are likely to be misled or confused by such variability. There is therefore a need to define and standardize many of these terms, to clarify reporting and to convey the correct information in a way that it is not misleading. This paper details the background and need for this and is primarily intended to assist those who intend to publish primary and secondary acupuncture research. However, standardization of reporting will be of benefit to anybody who will need to examine the literature for evidence. This article proposes and recommends a nomenclature when reporting future acupuncture clinical research. This nomenclature arose through discussion at a meeting convened by the World Health Organisation (Western Pacific Regional Office) and will be incorporated into their policy document later this year
Improving Postoperative Pain Control After Cesarean Delivery with Enhanced Recovery in Patients on Buprenorphine Therapy
Abstract:
Introduction:
Prescription drug abuse presents a significant challenge to the management of post operative pain.Pain control amongst the opioid addicted patient can be especially challenging. We aimed to improve pain control after caesarian delivery with enhanced recovery in patients who are on buprenorphine medication-assisted therapy for the treatment of opioid addiction.
Materials and Methods:
We conducted a pilot study by implementing a protocol using liposomal bupivacaine injected at the time of cesarean delivery. Patients were then given 500mg acetaminophen every 4 hours, 800mg ibuprofen every 8 hours and 0.3mg IV buprenorphine every 6 hours as needed. The patients’ maintenance dosing of buprenorphine was divided into doses throughout the day. In addition, patients were ambulated 4 hours after surgery and had their catheter removed from their bladder as soon as they could safely ambulate. Eleven patients were prospectively recruited and then compared to a retrospective sample of seventeen patients.
Results:
Patients in the treatment group reported 27% lower pain scores (p
Discussion:
Our enhanced recovery protocol is an effective alternative to traditional pain control and is associated with a significant reduction in both pain scores and use of breakthrough IV buprenorphine as well as lower charges
