Selected AbstractsFORECASTING DRY SEASON STREAMFLOW ON THE PEACE RIVER AT ARCADIA, FLORIDA, USA,JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 4 2006David M. Coley ABSTRACT: The Peace River at Arcadia, Florida, is a municipal water supply supplement for southwestern Florida. Consequently, probabilities of encountering low flows during the dry season are of critical importance. Since the association between Pacific Ocean sea surface temperatures (SSTs) and seasonal streamflow variability in the southeastern United States is well documented, it is reasonable to generate forecasts based on this information. Here, employing historic records of minimum, mean, and maximum flows during winter (JFM) and spring (AMJ), upper and lower terciles define "above normal,""normal," and "below normal" levels of each variable. A probability distribution model describes the likelihood of these seasonal variables conditioned upon Pacific SSTs from the previous summer (JAS). Model calibration is based upon 40 (of 50) years of record employing stratified random sampling to ensure equal representation from each decade. The model is validated against the remaining 10 samples and the process repeated 100 times. Each conditional probability distribution yields varying probabilities of observing flow variables within defined categories. Generally, a warm (cold) Pacific is associated with higher (lower) flows. To test model skill, the forecast is constrained to be the most probable category in each calibration year, with significance tested by chi-square frequency tables. For all variables, the tables indicate high levels of association between forecast and observed terciles and forecast skill, particularly during winter. During spring the pattern is less clear, possibly due to the variable starting date of the summer rainy season. This simple technique suggests that Pacific SSTs provide a good forecast of low flows. [source] WATER QUALITY IN AGRICULTURAL, URBAN, AND MIXED LAND USE WATERSHEDS,JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 6 2004Chris B. Coulter ABSTRACT: Water quality and nonpoint source (NPS) pollution are important issues in many areas of the world, including the Inner Bluegrass Region of Kentucky where urban development is changing formerly rural watersheds into urban and mixed use watersheds. In watersheds where land use is mixed, the relative contributions of NPS pollution from rural and urban land uses can be difficult to separate. To better understand NPS pollution sources in mixed use watersheds, surface water samples were taken at three sites that varied in land use to examine the effect of land use on water quality. Within the group of three watersheds, one was predominately agriculture (Agricultural), one was predominately urban (Urban), and a third had relatively equal representation of both types of land uses (Mixed). Nitrogen (N), phosphorus (P), total suspended solids (TSS), turbidity, pH, temperature, and streamflow were measured for one year. Comparisons are made among watersheds for concentration and fluxes of water quality parameters. Nitrate and orthophosphate concentrations were found to be significantly higher in the Agricultural watershed. Total suspended solids, turbidity, temperature, and pH, were found to be generally higher in the Urban and Mixed watersheds. No differences were found for streamflow (per unit area), total phosphorus, and ammonium concentrations among watersheds. Fluxes of orthophosphate were greater in the Agricultural watershed that in the Urban watershed while fluxes of TSS were greater in the Mixed watershed when compared to the Agricultural watershed. Fluxes of nitrate, ammonium, and total phosphorus did not vary among watersheds. It is apparent from the data that Agricultural land uses are generally a greater source of nutrients than the Urban land uses while Urban land uses are generally a greater source of suspended sediment. [source] Does Racial Balance in Workforce Representation Yield Equal Justice?LAW & SOCIETY REVIEW, Issue 4 2009Race Relations of Sentencing in Federal Court Organizations Increasing racial and ethnic group representation in justice-related occupations is considered a potential remedy to racial inequality in justice administration, including sentencing disparity. Studies to date yield little evidence of such an effect; however, research limitations may account for the mixed and limited evidence of the significance of justice workforce racial diversity. Specifically, few studies consider group-level dynamics of race and representation, thus failing to contextualize racial group power relations in justice administration. To consider these contextual dynamics we combine court organizational and case-level data from 89 federal districts and use hierarchical models to assess whether variably "representative" work groups relate to district-level differences in sentencing. Using district-specific indexes of population and work group dissimilarity to define representation, we find no relationships between black judge representation and sentencing in general across districts, but that districts with more black representation among prosecutors are significantly less likely to sentence defendants to terms of imprisonment. We also find in districts with increased black representation among prosecutors, and to a lesser degree among judges, that black defendants are less likely to be imprisoned and white defendants are more likely to be imprisoned, with the effect of narrowing black-white disparities in sentencing. Consistent with the "power-threat" perspective, and perhaps "implicit racial bias" research, findings encourage modeling diversity to account for relative racial group power in processes of social control and suggest that racial justice may be moderately advanced by equal representation among authorities. [source] FOOD INSECURITY IN BUHAYA: THE CYCLE OF WOMEN'S MARGINALIZATION AND THE SPREAD OF POVERTY, HUNGER, AND DISEASEANNALS OF ANTHROPOLOGICAL PRACTICE, Issue 1 2009Valerie Githinji This chapter focuses on how the marginalization of Bahaya women increases poverty, thus exacerbating issues of hunger and related disease in a region characterized by a history of environmental degradation, agricultural change and decline, rural poverty and disease. In the past several decades, diminishing sizes of banana farms, an overall decline in cattle, decreasing soil fertility, and an increase in food crop pathogens have posed challenges to achieving adequate agricultural yields in Buhaya of northwestern Tanzania. This situation has resulted in an increase in poverty, food insecurity, nutrition insecurity, and related disease. Culturally, women are the primary agriculturalists and producers and providers of food in Buhaya. However, Bahaya cultural practices hinder women from achieving equal representation in society, thus blocking their access to self advancement and resources such as money, land, education, and agricultural inputs. These constraints marginalize and hinder women from fulfilling their social role as primary farmers and provisioners of food, nutrition, and care. As patriarchal practices and ecological challenges work to constrain women's roles, poverty, food scarcity, and disease increase, affecting and weakening the foundation of Bahaya society and culture. [source] Characterisation of isolates of Staphylococcus aureus from acute, chronic and subclinical mastitis in cows in NorwayAPMIS, Issue 9 2000TORE Tollersrud Eighty-six Staphylococcus aureus isolates from cases of bovine mastitis were characterised biochemically and with respect to serotype, multilocus enzyme electrophoresis genotypes, antibiotic sensitivity, and production of enterotoxins A through D (SEA-D) and toxic shock syndrome toxin-1 (TSST-1). The samples were obtained from 81 different cows from 79 Norwegian dairy herds in 10 different counties in southern Norway. There was an equal representation of isolates from cases of acute, chronic and subclinical mastitis. Multilocus enzyme electrophoresis using 13 genetic loci showed that 69 of 86 isolates had the same electrophoretic type. This common electrophoretic type comprised isolates that differed in the expression of other phenotypical characteristics studied. Fifty-eight percent of the isolates produced one or more enterotoxins, predominantly a combination of SEC and TSST-1. Capsular serotyping revealed that 95% of the isolates belonged to serotype 8. No correlation was found between the factors studied and the clinical classification of mastitis. It appears that the majority of S. aureus isolates recovered from cases of bovine mastitis in Norway are genetically closely related and express common phenotypical characteristics. [source] Interpretation of two nutrition content claims: a New Zealand surveyAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 1 2010Delvina Gorton Abstract Objective: To determine how various population groups in New Zealand interpret the nutrition content claims ,97% fat free' and ,no added sugar' on food labels. Methods: A survey of adult supermarket shoppers was conducted at 25 Auckland supermarkets over a six-week period in 2007. Supermarkets were located in areas where greater than 10% of the resident population were known to be M,ori, Pacific or Asian, based on 2001 Census meshblock data. Four questions in the survey assessed understanding and interpretation of the nutrition content claims ,97% fat free' and ,no added sugar'. Results: There were 1,525 people who completed the survey, with approximately equal representation from M,ori, Pacific, Asian and New Zealand European and Other ethnicities. Nearly three-quarters (72%) of participants correctly estimated the fat content of a 100 g product that was ,97% fat free', and understood that a product with ,no added sugars' could contain natural sugar. However, up to three-quarters of M,ori, Pacific, and Asian shoppers assumed that if a food carried a ,97% fat free' or ,no added sugar' claim it was therefore a healthy food. Similarly, low-income shoppers were significantly more likely than medium- or high-income shoppers to assume that the presence of a claim meant a food was definitely healthy. Conclusion: Percentage fat free and no added sugar nutrition content claims on food are frequently misinterpreted by shoppers as meaning the food is healthy overall and appear to be particularly misleading for M,ori, Pacific, Asian and low-income groups. Implications: Nutrition content claims have potential for harm if the food they are placed on is not healthy overall. Such claims should therefore only be permitted to be placed on healthy foods.
