Cuando los Negros Luchaban (the Black Struggle): 1965 U.S. invasion of the Dominican Republic [abstract]
Abstract only availableOn April 22, 1965, in Santo Domingo, the Dominican Republic, left winged military men launched a coup against the U.S. backed president in order to restore the presidency of Juan Bosch, a proclaimed populist whom the United States had helped oust from power only months before. The backlash of the April coup involved the invasion of 14,000 U.S. troops into the Dominican Republic. In the eyes of the U.S. Department of State, the Dominican Republic, whose population contains ninety percent of individuals of African heritage, would not become another Cuba. In the United States, the stage of 1965 is set with contentious involvement in the Vietnam war, a large-scale civil rights movement steadily rolling along and gaining momentum and headed by African Americans, and a host of fearful and zealous Latin American foreign policies. Observing this scene, this paper raises the questions: How did black Americans respond to the United States' use of force towards their presumed “brothers” to the south? Did ideology override race in the international relations between blacks of the African Diaspora? Are the bonds of the African Diaspora as strong as intellectuals have historically suggested and advocated? Or are these bonds products of myth and merely tools for empowerment? Are they simply broken and in need of repair? Are there valid arguments for unity between members of the African Diaspora? In response to these inquiries, the paper places obstacles before the perpetuators of modern-day “racial” classifications, cultural perspectives, and political assumptions, in preparation to renew the discourse surrounding blacks of the world
Recent Developments: The Uniform Arbitration Act
Recent Developments: The Uniform Arbitration Act, a project prepared annually since 1983, is a survey of recent court decisions that interpret state versions of the Uniform Arbitration Act ( U.A.A. ). 3 Currently, thirty-four states and the District of Columbia have adopted arbitration statutes patterned after the U.A.A. 4 The purpose of this project is to promote uniformity in interpretation of the U.A.A. by explaining the underlying policies and rationales of recent court decisions.\u2

Undergraduate nursing studies: the first-year experience
The transfer of nursing education into the tertiary section in Australia aimed to address a number of issues for nursing, the most significant of which was to enhance the status of the profession. A side effect of the establishment of university-based nursing programs is the increased flexibility that makes studies in nursing an option for students who may otherwise not have had this opportunity. Such accessibility is not without problems as many students enter tertiary nursing programs after a prolonged period of absence from a scholarly environment. Those who do enrol directly from other forms of study are often overwhelmed by the specific requirements of nursing programs. In order to promote student succession and reduce attrition, universities have established a number of mechanisms to support students as they transition to the tertiary environment. This article reports on a survey of 112 nursing students enrolled in their first year of study at a regional university in Australia.
Findings are presented under the major areas of questions, these being, issues faced in adapting to the role of a university student in the first year of study, services or support mechanisms accessed to assist in transition to the role of university student, and services lacking that would have assisted in the transition to the role of university student. These findings are then discussed in the context of existing knowledge of the first-year experience of university students
Fate of tetracycline and sulfonamide resistance genes in a grassland soil amended with different organic fertilizers
This study provided an assessment of the environmental fate of antibiotic resistance genes (ARGs) in a Scottish grassland field repeatedly treated with different organic fertilizers. The impacts of manure, biosolids and municipal food-derived compost on the relative abundances of tetracycline ARGs (tetA, tetB, tetC, tetG and tetW), sulfonamide ARGs (sul1 and sul2) and class 1 integron-integrase gene (IntI1) in soils were investigated, with inorganic fertilizer (NPK) as a comparison. The background soil with a history of low intensity farming showed a higher total relative abundance of tet ARGs over sul ARGs, with tetracycline efflux genes occurring in a higher frequency. In all treatments, the relative abundances of most ARGs detected in soils decreased over time, especially IntI1 and tet ARGs. This general attenuation of soil ARGs is a reflection of changes in the soil microbial community, which is supported by the result that almost all the soils at the end of the experiment had different bacterial communities from the untreated soil at the beginning of the experiment. Multiple applications of organic fertilizers to some extent counteracted the decreasing trend of soil ARGs relative abundances, which resulted in higher ARGs relative abundances in comparison to NPK, either by a lesser decrease of IntI1 and tet ARGs or an increase of sul ARGs. The enhancement of existing soil ARG prevalence by organic fertilizers was strongly dependent on the organic fertilizer type and the particular ARG. Compost contained the lowest relative abundance of inherent ARGs and had the least effect on the soil ARG decrease after application. The relative increase of tet ARGs caused by biosolids was larger than that of sul ARGs, while manure caused the opposite effect. Fertilization practices did not exert effective impacts on the soil bacterial community, although it caused significant changes in the profile of the ARG pool. Organic fertilization may thus accelerate the dissemination of ARGs in soil mainly through horizontal gene transfer (HGT), consistent with the enrichment of IntI1 in organic fertilized soils
Double Red Blood Cell Donation Eligibility and Interest
Introduction: The process of double RBC donation by apheresis (DRBC), which facilitates the donation of two units of red blood cells (RBC) in a single donation session, was estimated to account for approximately 4% of blood donations in 2005, and is believed to be growing at a rate of 40% per year. Blood shortages in this country could be corrected by converting as few as 10% of current single unit whole blood donors to DRBC donors. Advantages of DRBC donation may include reduction in donor-related exposures in recipients, improved cost-effectiveness of the donation process, and improved convenience for donors. The safety profile of DRBC has been found to be equal to, and in some cases better than that of single unit whole blood donation, especially in young donors (/o). DRBC donors have been shown to restore 92% of RBC volume in 4 weeks without iron supplementation, and to have no significant differences in hemoglobin, serum iron, or ferritin when compared with single unit whole blood donors six months after donation. Our study seeks to quantify the number of current single unit whole blood donors who are both eligible for and interested in DRBC donation.https://scholarworks.uvm.edu/comphp_gallery/1031/thumbnail.jp
Ultraviolet Spectroscopy of Asteroid (4) Vesta
We report a comprehensive review of the UV-visible spectrum and rotational
lightcurve of Vesta combining new observations by Hubble Space Telescope and
Swift Gamma-ray Burst Observatory with archival International Ultraviolet
Explorer observations. The geometric albedos of Vesta from 220 nm to 953 nm are
derived by carefully comparing these observations from various instruments at
different times and observing geometries. Vesta has a rotationally averaged
geometric albedo of 0.09 at 250 nm, 0.14 at 300 nm, 0.26 at 373 nm, 0.38 at 673
nm, and 0.30 at 950 nm. The linear spectral slope as measured between 240 and
320 nm in the ultraviolet displays a sharp minimum near a sub-Earth longitude
of 20^{\circ}, and maximum in the eastern hemisphere. This is consistent with
the longitudinal distribution of the spectral slope in the visible wavelength.
The photometric uncertainty in the ultraviolet is ~20%, and in the visible
wavelengths it is better than 10%. The amplitude of Vesta's rotational
lightcurves is ~10% throughout the range of wavelengths we observed, but is
smaller at 950 nm (~6%) near the 1-\mum band center. Contrary to earlier
reports, we found no evidence for any difference between the phasing of the
ultraviolet and visible/near-infrared lightcurves with respect to sub-Earth
longitude. Vesta's average spectrum between 220 and 950 nm can well be
described by measured reflectance spectra of fine particle howardite-like
materials of basaltic achondrite meteorites. Combining this with the in-phase
behavior of the ultraviolet, visible, and near-infrared lightcurves, and the
spectral slopes with respect to the rotational phase, we conclude that there is
no global ultraviolet/visible reversal on Vesta. Consequently, this implies a
lack of global space weathering on Vesta, as previously inferred from
visible-near-infrared data.Comment: 44 pages, 5 figures, 1 tabl

MAMBO 1.2mm observations of luminous starbursts at z~2 in the SWIRE fields
We report on--off pointed MAMBO observations at 1.2 mm of 61 Spitzer-selected
star-forming galaxies from the SWIRE survey. The sources are selected on the
basis of bright 24um fluxes (f_24um>0.4mJy) and of stellar dominated
near-infrared spectral energy distributions in order to favor z~2 starburst
galaxies. The average 1.2mm flux for the whole sample is 1.5+/-0.2 mJy. Our
analysis focuses on 29 sources in the Lockman Hole field where the average
1.2mm flux (1.9+/-0.3 mJy) is higher than in other fields (1.1+/-0.2 mJy). The
analysis of the sources multi-wavelength spectral energy distributions
indicates that they are starburst galaxies with far-infrared luminosities
~10^12-10^13.3 Lsun, and stellar masses of ~0.2-6 x10^11 M_sun. Compared to
sub-millimeter selected galaxies (SMGs), the SWIRE-MAMBO sources are among
those with the largest 24um/millimeter flux ratios. The origin of such large
ratios is investigated by comparing the average mid-infrared spectra and the
stacked far-infrared spectral energy distributions of the SWIRE-MAMBO sources
and of SMGs. The mid-infrared spectra exhibit strong PAH features, and a warm
dust continuum. The warm dust continuum contributes to ~34% of the mid-infrared
emission, and is likely associated with an AGN component. This constribution is
consistent with what is found in SMGs. The large 24um/1.2mm flux ratios are
thus not due to AGN emission, but rather to enhanced PAH emission compared to
SMGs. The analysis of the stacked far-infrared fluxes yields warmer dust
temperatures than typically observed in SMGs. Our selection favors warm
ultra-luminous infrared sources at high-z, a class of objects that is rarely
found in SMG samples. Our sample is the largest Spitzer-selected sample
detected at millimeter wavelengths currently available.Comment: Accepted for publication in ApJ (51 pages; 16 figures). The quality
