Average sedimentary rock rare Earth element patterns and crustal evolution: Some observations and implications from the 3800 Ma ISUA supracrustal belt, West Greenland

Rare earth element (REE) data is given on a set of clastic metasediments from the 3800 Ma Isua Supracrustal belt, West Greenland. Each of two units from the same sedimentary sequence has a distinctive REE pattern, but the average of these rocks bears a very strong resemblance to the REE pattern for the North American Shale Composite (NASC), and departs considerably from previous estimates of REE patterns in Archaean sediments. The possibility that the source area for the Isua sediments resembled that of the NASC is regarded as highly unlikely. However, REE patterns like that in the NASC may be produced by sedimentary recycling of material yielding patterns such as are found at Isua. The results lead to the following tentative conclusions: (1) The REE patterns for Isua Seq. B MBG indicate the existence of crustal materials with fractionated REE and negative Eu anomalies at 3800 Ma, (2) The average Seq. B REE pattern resembles that of the North American Shale Composite (NASC), (3) If the Seq. B average is truly representative of its crustal sources, then this early crust could have been extensively differentiated. In this regard, a proper understanding of the NASC pattern, and its relationship to post-Archaean crustal REE reservoirs, is essential, (4) The Isua results may represent a local effect

Food cost and availability in a rural setting in Australia

Introduction: The burden of chronic diseases is rapidly increasing worldwide. In&nbsp; Australia rural populations have a greater burden of disease. Chronic diseases are largely preventable with diet as a key risk factor. With respect to diet-related chronic disease, dietary risk may be due to poor food access, namely, poor availability and/or the high cost of healthy food. It is likely that poor food access is an issue in rural areas. Objective: To assess food access in rural south-west (SW) Victoria, Australia.Methods: A total of 53 supermarkets and grocery stores in 42 towns participated in a survey of food cost and availability in the rural area of SW Victoria. The survey assessed availability and cost of a Healthy Food Access Basket (HFAB) which was designed to meet the nutritional needs of a family of 6 for 2 weeks.Results: Seventy-two percent of the eligible shops in SW Victoria were surveyed. The study found that the complete HFAB was significantly more likely to be available in a town with a chain-owned store (p&lt;0.00). The complete HFAB was less likely to be available from an independently owned store in a town with only one grocery shop (p&lt;0.004). The average cost of the HFAB across SW Victoria was AU380.30 ± 25.10 (mean &plusmn; SD). There was a mean range in difference of cost of the HFAB of $36.92. In particular, high variability was found in the cost of fruits and vegetables.Conclusions: Cost and availability of healthy food may be compromised in rural areas. Implications: Improvements in food access in rural areas could reduce the high burden of disease suffered by rural communities.<br /

Condensed summary of the systems prioritization method as a decision-aiding approach for the Waste Isolation Pilot Plant

In March 1994, the US Department of Energy Carlsbad Area Office (DOE/CAO) implemented a performance based decision-aiding method to assist in programmatic prioritization within the Waste Isolation Pilot Plant (WIPP) project. The prioritization was with respect to 40 CFR Part 191.13(a) and 40 CFR part 268.6. U.S. Environmental Protection Agency (EPA) requirements for long-term isolation of radioactive and hazardous wastes. The Systems Prioritization Method (SPM), was designed by Sandia National Laboratories to: (1) identify programmatic options (activities), their costs and durations; (2) analyze combinations of activities in terms of their predicted contribution to long-term performance of the WIPP disposal system; and (3) analyze cost, duration, and performance tradeoffs. SPM results were the basis for activities recommended to DOE/CAO in May 1995. SPM identified eight activities (less than 15% of the 58 proposed for consideration) predicted to be essential in addressing key regulatory issues. The SPM method proved useful for risk or performance-based prioritization in which options are interdependent and system behavior is nonlinear. 10 refs., 2 figs., 1 tab

An Exploratory Approach to Analyzing Alcohol Control Policy Opinions Held by Ontario Adults

Telephone interview data from a representative sample of 1,216 Ontario adults were analyzed using latent class analysis to determine whether distinct and homogeneous classes of individuals could be identified based on their responding patterns to 11 alcohol policy items. Five latent classes were identified and labeled as: dedicated liberalizers, moderate liberalizers, moderate controllers, dedicated controllers, and an ambivalent class. Multinomial regression analysis indicated that demographic and alcohol factors differentiated the classes. Those most opposed to alcohol controls, dedicated liberalizers, were more likely to be male, younger and heavier drinkers. Given their young age it is possible that further erosion of public support for alcohol controls may be expected

Longitudinal associations of importance of religion and frequency of service attendance with depression risk among adolescents in Nova Scotia

Objective: To examine the directionality of associations between self-reported religious importance or worship attendance and depression among adolescents, and to determine whether social supports or general self-efficacy are mechanisms of observed associations. Method: A cohort (n = 976) of Canadian high school students were surveyed in Grade 10 (2000 to 2001) and 2 years later (2002 to 2003). Logistic regression was conducted separately among adolescents with and without elevated depressive symptoms to examine associations between baseline religious attendance and religious importance with later depression, adjusting for confounding factors. Effects of reverse causation were also assessed, determining associations between baseline depression and follow-up religious attendance and importance. Results: Girls who were not depressed at baseline and who attended religious services had lower odds of later depression (adjusted odds ratio [AOR] 0.46; 95% CI 0.22 to 0.95, P < 0.05), which was accounted for by general self-efficacy. Boys who were depressed at baseline who attended religious services had lower odds of still being depressed at followup (AOR 0.23; 95% CI 0.06 to 0.80, P < 0.01). Depression at baseline predicted lower attendance at follow-up among boys (AOR 0.26; 95% CI 0.09 to 0.75, P < 0.01). Conclusions: Religious attendance independently predicts lower depression at followup among girls, and may do so by increasing self-efficacy. Among boys with depression, religious attendance predicts a lower likelihood of still being depressed at follow-up. The relation between religious attendance and depression in boys is bidirectional

Cerebral blood flow predicts differential neurotransmitter activity

Application of metabolic magnetic resonance imaging measures such as cerebral blood flow in translational medicine is limited by the unknown link of observed alterations to specific neurophysiological processes. In particular, the sensitivity of cerebral blood flow to activity changes in specific neurotransmitter systems remains unclear. We address this question by probing cerebral blood flow in healthy volunteers using seven established drugs with known dopaminergic, serotonergic, glutamatergic and GABAergic mechanisms of action. We use a novel framework aimed at disentangling the observed effects to contribution from underlying neurotransmitter systems. We find for all evaluated compounds a reliable spatial link of respective cerebral blood flow changes with underlying neurotransmitter receptor densities corresponding to their primary mechanisms of action. The strength of these associations with receptor density is mediated by respective drug affinities. These findings suggest that cerebral blood flow is a sensitive brain-wide in-vivo assay of metabolic demands across a variety of neurotransmitter systems in humans
