Geochemical and biogeochemical studies in the Hansonburg Mining District, New Mexico

The Hansonburg mining district is in Socorro county in south central New Mexico. A Paleozoic section of thick Pennsylvanian limestone units, thin shale and arkose layers and thick Permian units of sandstone, siltstone and gypsiferous beds interlayered with thin limestone units unconformably overlie a Precambrian basement of granite. The sedimentary rocks are folded with north trends and plunges. Northerly, some easterly and northwesterly trending faults cut the folds. Galena, fluorite, and barite mineralization occurs along some of the northerly faults and as bedded replacements and fissure fillings in the Pennsylvanian Council Spring limestone. Geological mapping and geochemical soil surveys of the northwestern part of the mining district indicate four major heavy metal anomalous areas and possible regional zoning of the metals. Copper values range from a low of 2.8 ppm to a high of 67.0 ppm. Lead values ranged from 5.3 ppm to 56 ppm, and zinc from below detection limit to 38.0 ppm. Heavy metal determinations were made of soil and Creosote bush samples that were collected across a mineralized fault breccia zone of the Oscura fault. Results show that the lead values in soils in test profiles have distinct anomalous areas which range from 11.5 to 98.0 ppm. Copper and zinc anomalies are also distinct, but, with smaller ranges of 3.5 to 16.0 ppm and 3.0 to 21.5 ppm, respectively. Heavy metals in Creosote bush samples show similar anomalous zones, but copper has the greatest range (12.0 to 65.0 ppm). The range of lead is 5.0 to 28.0 ppm and for zinc, 10.5 to 21.5 ppm. A rising trend of copper and zinc and constant lead content in sediments upstream along the Julian Arroyo suggests possible mineralization within the Alamogordo Bombing Range --Abstract, pages ii-iii

An Examination of the Antidumping Provisions of the Trade Agreements Act of 1979: United States Implementation of the Antidumping Code Formulated in the Tokyo Round

The purposes of the antidumping provisions of the Trade Agreements Act are to discourage price discrimination practices and the sale of unfairly priced import goods in the United States, and to off er remedies for the injury suffered by domestic industry when such practices occur. It is, in essence, intended to be preventive and not punitive. Nevertheless the Act, which in both design and application will present undue hardships to foreign producers and developing countries, fails to adequately address the global operations of multinational corporations and is susceptible to protectionist designs

Case Mix, Costs, and Outcomes: Differences Between Faculty and Community Services in a University Hospital

In order to gain insight into the possible consequences of prospective payment for university hospitals, we studied 2,025 admissions to the faculty and community services of a university hospital, measuring differences in case mix, costs, and outcomes. The faculty service case mix was disproportionately weighted toward the more costly diagnoses, but even after adjustment for diagnosis-related groups (DRGs), costs were 11 percent higher on the faculty service. The differential was proportionately greater for diagnostic costs than for routine or treatment costs, and the differential was particularly large (70 percent) for patients with a predicted probability of death (DTHRISK) of .25 or greater.The in-hospital mortality rate was appreciably lower on the faculty service after adjustment for case mix and patient characteristics. The mortality differential between the two services was particularly large for patients in the high death risk category. Comparison of a matched sample of 51 pairs of admissions from the high death risk category confirmed the above results with respect to costs and in-hospital mortality, but follow-up revealed that the mortality rates were equal for the two services at nine months after discharge.

Complicated Open Wound Management in a Free Clinic Setting

Wound healing is a complex and integrated process that involves several interdependent overlapping stages, including hemostasis, inflammation, proliferation, and vascularization. Cellulitis and skin abscesses are among the most common skin and soft tissue infections. Cellulitis typically involves the deeper dermis of subcutaneous fat and tends to have a more indolent course with the development of localized symptoms over a few days. Skin abscesses are described as a collection of pus within the dermis or subcutaneous space. Diabetes mellitus (DM) is the leading cause of impaired wound healing and consequently has higher rates of patients developing soft tissue infections. Diabetic patients experience decreased early inflammatory cell infiltration but increased numbers of neutrophils and macrophages. Complications include bacteremia, metastatic infection, sepsis, and toxic shock syndrome. In this case, we describe a 50-year-old Caucasian uninsured male who was referred to the Gary Burnstein Clinic (GBC) from a nearby hospital for wound management after an incision and drainage of a large back abscess and uncontrolled type 2 diabetes mellitus (T2DM). The patient presented with a large erythematous, indurated lesion with a cruciate incision that spanned from his mid-thoracic spine to the medial border of his left scapula. The wound management course required strict follow-up to the clinic every 48-72 hours for debridement and monitoring. This was complicated by the GBC\u27s limited resources along with the volunteer nurses\u27 and physicians\u27 availability. To avoid the patient being lost to follow-up, shared decision-making was utilized to create a schedule that was advantageous for both the patient and the clinic. Ultimately, the patient made a full recovery without any adverse events. This case highlights the gaps in care for the medically uninsured. We also showcase the passion and dedication our medical volunteers exhibit to care for the community. The GBC provides high-quality healthcare to bridge gaps in access to care by offering broad specialist access while ensuring continuity of care

‘Jugglers’, ‘copers’ and ‘strugglers’: academics’ perceptions of being a head of department in a post-1992 UK university and how it influences their future careers

This study investigates the experiences of academics who became department heads in a post-1992 UK university and explores the influence that being in the position has on their planned future academic career. Drawing on life history interviews undertaken with 17 male and female heads of department, the paper constitutes an in-depth study of their careers in the same university. The findings suggest that academics who become department heads not only need the capacity to assume a range of personal and professional identities, but need flexibility to regularly adopt and switch between them. Whether individuals can successfully balance and manage such multiple identities, or whether they experience major conflicts within or between them, greatly affects their experiences of being a head of department and seems to influence their subsequent career decisions. The paper concludes by proposing a conceptual framework and typology to interpret the career trajectories of academics that became department heads in the case university
