| public health: tobacco taxes and internet sales--2005. end of year issue brief. | raising tobacco taxes is an action that resonates with lawmakers, public health and anti-tobacco advocates, and the majority of the electorate. the relatively broad base of support for increasing excise taxes and the potential for increased tax revenue mitigate the concerns over targeting tobacco-users--23 percent of the population--to pay for state programs and the unreliability of the tobacco tax as a permanent source of revenue. tobacco excise taxes generated $10.2 billion, or about 1.5 perce ... | 2005 | 16715554 |
| estimating hiv incidence and detection rates from surveillance data. | markov models that incorporate hiv test information can increase precision in estimates of new infections and permit the estimation of detection rates. the purpose of this study was to assess the functioning of a markov model for estimating new hiv infections and hiv detection rates in louisiana using surveillance data. | 2004 | 15127908 |
| implications of proposed changes in bulk tank somatic cell count regulations. | several changes in bulk tank scc (btscc) regulations were proposed at the 1998 annual meeting of the national conference of interstate milk shippers (ncims) by the national mastitis council and other proponents. proposals included 1) using a geometric mean btscc in place of the arithmetic mean, reducing the current limit for btscc from 750,000 to 400,000, and modifying current regulatory protocols. the purpose of this research was to evaluate possible impacts of proposed changes upon producers i ... | 2001 | 11233021 |
| attitudes and practices of pharmacy managers regarding needle sales to injection drug users. | to determine louisiana pharmacy managers' attitudes and practices regarding needle and syringe sales to suspected injection drug users (idus) without prescriptions, and to assess which factors affect their decisions to sell nonprescription needles and syringes. | 1999 | 9990183 |
| a multistate outbreak of oyster-associated gastroenteritis: implications for interstate tracing of contaminated shellfish. | in november 1993, clusters of gastroenteritis in six states following oyster consumption were investigated to identify common features, and stool samples were obtained to identify a pathogen. efforts were made to account for all potentially contaminated oysters using harvest tags and the interstate recall system. consumption of oysters was associated with illness in 10 clusters; no other food was implicated. a norwalk-like virus was detected by electron microscopy in 9 of 18 samples and by rever ... | 1995 | 7769284 |
| a dynamic life table model of psorophora columbiae in the southern louisiana rice agroecosystem with supporting hydrologic submodel. part 2. model validation and population dynamics. | in an earlier paper, the development of 2 simulation models designed to describe the interaction between key elements of the rice agroecosystem and the population dynamics of psorophora columbiae were presented (focks et al. 1988a). the objective of the work reported herein was to validate these models with field data. the first model (watermod) predicts soil hydrology conditions as a function of weather, agricultural practices, and soil characteristics for a variety of habitats found within the ... | 1988 | 2904484 |
| potential oversummering and overwintering regions for the wheat stripe rust pathogen in the contiguous united states. | epidemics of wheat stripe rust, caused by puccinia striiformis f. sp. tritici (pst), are more frequent in the regions where pst can oversummer and overwinter. regions for potential oversummering and overwintering of pst were determined in the contiguous united states using a survival index (si) ranging from 0 (most unfavorable) to 10 (most favorable) developed based on long-term weather data. the pathogen can survive in cool summer in the most regions north of latitude 40°n, particularly washing ... | 2014 | 23722926 |
