New law may be having some effect on publication bias.
P ositive trials get reported more often than negative trials, according to many studies. And despite efforts in the past decade to combat publication bias, it remains a substantial problem, according to two articles published last fall. One found that results had been published from fewer than half of the trials registered in the federal database, clinicaltrials.gov. The second article found t...
متن کاملSome consequences of having too little.
Poor individuals often engage in behaviors, such as excessive borrowing, that reinforce the conditions of poverty. Some explanations for these behaviors focus on personality traits of the poor. Others emphasize environmental factors such as housing or financial access. We instead consider how certain behaviors stem simply from having less. We suggest that scarcity changes how people allocate at...
متن کاملSome Large Trivalent Graphs Having Small Diameters
Kantor, W.M., Some large trivalent graphs having small diameters, Discrete Applied Mathematics 37/38 (1992) 353-357. If Iz 2 10, then there is a tnvalent Cayley graph for G =PSL (n. y) whose diameter is O(logla). This paper concerns an improvement of a result of Babai, Kantor and Lubotzky [ 11. In that paper it was shown that there is a constant C such that every non-Abelian finite simple group...
متن کاملA Spatiotemporal-chaos-based Encryption Having Overall Properties Considerably Better Than Advanced Encryption Standard
Spatiotemporal chaos of a two-dimensional one-way coupled map lattice is used for chaotic cryptography. The chaotic outputs of many space units are used for encryption simultaneously. This system shows satisfactory cryptographic properties of high security; fast encryption (decryption) speed; and robustness against noise disturbances in communication channel. The overall features of this spatio...
متن کاملMutation Selection: Some Could be Better than All
In previous research, many mutation selection techniques have been proposed to reduce the cost of mutation analysis. After a mutant subset is selected, researchers could obtain a test suite which can detect all mutants in the mutant subset. Then they run all mutants over this test suite, and the detection ratio to all mutants is used to evaluate the effectiveness of mutation selection technique...
