Estimates of price and scale elasticities for U.S. consumed shrimp are derived using aggregate shrimp data differentiated by source country. Own-price elasticities for all countries had the expected negative signs, were statistically significant, and inelastic. The scale elasticities for all countries were positive and statistically significant at the 1% level with only the United States and Ec...

We provide a method for constructing a set of four-photon states suitable for quantum communication applications. Among these states is a set of concatenated quantum code states that span a decoherence-free subspace that is robust under collective-local as well as global dephasing noise. This method requires only the use of spontaneous parametric down-conversion, quantum state post-selection, a...

children need to learn to use the roads safety. road safety is essential for children’s freedom, development and exercise. when walking near a road it is a good idea to: 1. hold your child's hand. 2. don't let them run ahead. 3. look out for and encourage your child to be aware of hidden entrances or driveways crossing the pavement. 4. put reins on a younger child if they're not ...

The Bureau of Alcohol, Tobacco and Firearms (”BATF”), an agency of the United States Treasury Department, has wide-ranging law enforcement responsibilities, which include the investigation of crimes involving guns, explosives, and illicit drugs. Its execution of these duties has been the subject of considerable controversy. This Study reports evidence that the law enforcement activities of the ...

Introduction. Systematic evaluation is an integral part of the organization and delivery of community oral health care programmes, ensuring the effectiveness of these community-based interventions. This study aimed to assess the knowledge and practice of primary health care (PHC) personnel regarding their duties toward oral health. Methods and Material. A cross-sectional study was carried out a...

Vehicle crashes are amongst the major causes of mortality and results in losses of lives and properties. A large number of the vehicle crashes occur on rural roads. Accidents become more noteworthy in two-lane roads due to going and coming traffic. Therefore, prediction of crashes and their causes are considerably important to reduce the number and severity of the accidents. The safety index is...

This paper investigates the internal mechanism of trucker’s willingness to use familiar roads by constructing a structural equation model road loyalty, in which influence “emotional value” is additionally considered. The proposed method can be used understand psychological needs improve level service. Based on questionnaire data, AMOS software was analyze correlations and corresponding paramete...

Roads and vehicular traffic are among the most pervasive of threats to biodiversity because they fragmenting habitat, increasing mortality and opening up new areas for the exploitation of natural resources. However, the number of vehicles on roads is increasing rapidly and this is likely to continue into the future, putting increased pressure on wildlife populations. Consequently, a major chall...
