Black Appalachian Families

The black family in America has been subjected to social change more than the family of any other racial or ethnic group. An overview of its adjustment through successive crises of African transplantation, slavery, sudden emancipation, migration to cities and the vicissitudes of second-class citizenship help in understanding the black family\u27s contemporary forms. The black family of Appalachia faces yet another problem - (INVISIBILITY

Discovery of the Skull of a Grizzly Bear in Labrador

The skull of a small, young adult grizzly bear was discovered in the course of archaeological excavation of an early historic Eskimo house in northern Labrador. This discovery confirms the rumoured presence of Ursus arctos in Labrador in the eighteenth and nineteenth centuries. It is suggested that the Labrador grizzly represents an eastward extension of the barren-ground grizzly population across the mouth of Hudson Bay

Presidential Campaign and the 1st Amendment

Dorset Settlement and Subsistence in Northern Labrador

Archaeological surveys in northern Labrador have supplemented previous evidence from the central coast concerning the Dorset subsistence-settlement system. The evidence suggests a flexible Dorset economic base capable of exploiting a wide variety of environments, but lacking full development of certain food procurement systems that would later become important in Thule culture. In particular, site location and faunal analysis indicate that breathing hole sealing was not strongly developed by the Dorset, and that winter and spring settlement was oriented toward ice edge seal and walrus hunting

The Determinants of Investment in Petroleum Reserves and Their Implications for Public Policy

Interest in the determinants of investment in crude oil and natural gas reserves derives from three sources. First, it is always interesting to find a satisfactory explanation of investment behavior in any industry. Second, an aspect of the current concern with the energy crisis is the domestic crude petroleum industry\u27s productive capacity, which is an increasing function of the stock of proved oil and gas reserves. Third, there is a decades-old controversy over the special provisions of the federal corporation income tax law which apply to petroleum producers. The article presents a model of investment in proved reserves in the U.S. crude petroleum producing industry. The empirical results indicate that investment in petroleum reserves depended on three public policies: the special federal tax pro- visions, state market-demand prorationing, and the federal oil import quota. It is possible to draw some tentative policy conclusions from our empirical results, although a complete analysis of the three public policies will require additional empirical estimates

Black-Scholes option pricing within Ito and Stratonovich conventions

Options financial instruments designed to protect investors from the stock market randomness. In 1973, Fisher Black, Myron Scholes and Robert Merton proposed a very popular option pricing method using stochastic differential equations within the Ito interpretation. Herein, we derive the Black-Scholes equation for the option price using the Stratonovich calculus along with a comprehensive review, aimed to physicists, of the classical option pricing method based on the Ito calculus. We show, as can be expected, that the Black-Scholes equation is independent of the interpretation chosen. We nonetheless point out the many subtleties underlying Black-Scholes option pricing method.Comment: 14 page

Antidepressant use and risk of adverse outcomes in people aged 20–64 years: cohort study using a primary care database

Background: Antidepressants are one of the most commonly prescribed medications in young and middle-aged adults, but there is relatively little information on their safety across a range of adverse outcomes in this age group. This study aimed to assess associations between antidepressant treatment and several adverse outcomes in people aged 20–64 years diagnosed with depression. Methods: We conducted a cohort study in 238,963 patients aged 20–64 years registered with practices across the UK contributing to the QResearch primary care database. Only patients with a first diagnosis of depression were included. Outcomes were falls, fractures, upper gastrointestinal bleed, road traffic accidents, adverse drug reactions and all-cause mortality recorded during follow-up. Cox proportional hazards models were used to estimate hazard ratios associated with antidepressant exposure adjusting for potential confounding variables. Results: During 5 years of follow-up, 4651 patients had experienced a fall, 4796 had fractures, 1066 had upper gastrointestinal bleeds, 3690 had road traffic accidents, 1058 had experienced adverse drug reactions, and 3181 patients died. Fracture rates were significantly increased for selective serotonin reuptake inhibitors (adjusted hazard ratio 1.30, 95% CI 1.21–1.39) and other antidepressants (1.28, 1.11–1.48) compared with periods when antidepressants were not used. All antidepressant drug classes were associated with significantly increased rates of falls. Rates of adverse drug reactions were significantly higher for tricyclic and related antidepressants (1.54, 1.25–1.88) and other antidepressants (1.61, 1.22–2.12) compared with selective serotonin reuptake inhibitors. Trazodone was associated with a significantly increased risk of upper gastrointestinal bleed. All-cause mortality rates were significantly higher for tricyclic and related antidepressants (1.39, 1.22–1.59) and other antidepressants (1.26, 1.08–1.47) than for selective serotonin reuptake inhibitors over 5 years but not 1 year, and were significantly reduced after 85 or more days of treatment with selective serotonin reuptake inhibitors. Mirtazapine was associated with significantly increased mortality rates over 1 and 5 years of follow-up. Conclusions: Selective serotonin reuptake inhibitors had higher rates of fracture than tricyclic and related antidepressants but lower mortality and adverse drug reaction rates than the other antidepressant drug classes. The association between mirtazapine and increased mortality merits further investigation. These risks should be carefully considered and balanced against potential benefits for individual patients when the decision to prescribe an antidepressant is made
