A Nice Place to Visit But I Wouldn\u27t Want to Litigate There: The Effects of Cybersell v. Cybersell on the Law of Personal Jurisdiction

In a world divided by barriers of language and culture, the Internet is the nexus that connects the most rural outposts of technology to the global business centers. The Internet\u27s most popular user interface, the World Wide Web, is an interwoven network of computers through which news and information can traverse international barriers in a matter of seconds. Using an Internet Service Provider ( ISP ) and a personal computer, the average user can access the World Wide Web and enter the largest repository of public information on the planet. The boundaries are virtually limitless, and the general absence of content restrictions promotes the Internet as a realm where information costs approach zero

Impact: What Influences Finance Research?

Which journal articles have had the most impact on finance research? Which journals dominated finance research in the 1990s? We answer these and similar questions using a comprehensive sample of journals, an extensive time period, and a new ranking method that avoids problems inherent in the existing literature. Among our findings: six of the 10 articles most highly cited by finance journals were published in econometrics or economics journals; Journal of Finance has the most citations, but it accounts for only one of the top 10 articles; and Journal of Financial Economics has the highest impact per article

The Information Content of Short Interest: A Natural Experiment

Few studies have examined the relationship between customer injustice and employees’ retaliatory counterproductive behaviors toward customers, and those that have done so were conducted in a Western setting. We extend these studies by examining the relationship in a Singaporean context where retaliatory behaviors by employees might be culturally constrained. While the previously-established positive relationship between customer injustice and counterproductive behaviors was not replicated using peer-reported data from employees across two hotels in Singapore, we found that individuals’ self-efficacy and perceived social support moderated it. Specifically, the injustice-to-counterproductive behaviors relationship was positive for individuals with high self-efficacy, and for those who perceived high levels of supervisor social support. The findings offer insights into when Singaporean employees and, potentially, employees from other Confucian Asian societies will retaliate against customer injustice, and provide practical implications of how managers can help employees cope with customer injustice

SLC30A3 (ZnT3) Oligomerization by Dityrosine Bonds Regulates Its Subcellular Localization and Metal Transport Capacity

Non-covalent and covalent homo-oligomerization of membrane proteins regulates their subcellular localization and function. Here, we described a novel oligomerization mechanism affecting solute carrier family 30 member 3/zinc transporter 3 (SLC30A3/ZnT3). Oligomerization was mediated by intermolecular covalent dityrosine bonds. Using mutagenized ZnT3 expressed in PC12 cells, we identified two critical tyrosine residues necessary for dityrosine-mediated ZnT3 oligomerization. ZnT3 carrying the Y372F mutation prevented ZnT3 oligomerization, decreased ZnT3 targeting to synaptic-like microvesicles (SLMVs), and decreased resistance to zinc toxicity. Strikingly, ZnT3 harboring the Y357F mutation behaved as a “gain-of-function” mutant as it displayed increased ZnT3 oligomerization, targeting to SLMVs, and increased resistance to zinc toxicity. Single and double tyrosine ZnT3 mutants indicate that the predominant dimeric species is formed between tyrosine 357 and 372. ZnT3 tyrosine dimerization was detected under normal conditions and it was enhanced by oxidative stress. Covalent species were also detected in other SLC30A zinc transporters localized in different subcellular compartments. These results indicate that covalent tyrosine dimerization of a SLC30A family member modulates its subcellular localization and zinc transport capacity. We propose that dityrosine-dependent membrane protein oligomerization may regulate the function of diverse membrane protein in normal and disease states

Additive Noise Induces Front Propagation

The propagation of a front connecting a stable homogeneous state with a stable periodic state in the presence of additive noise is studied. The mean velocity was computed both numerically and analitically. The numerics are in good agreement with the analitical prediction.Comment: 4 pages, 5 figure

Measuring The Evolutionary Rate Of Cooling Of ZZ Ceti

We have finally measured the evolutionary rate of cooling of the pulsating hydrogen atmosphere (DA) white dwarf ZZ Ceti (Ross 548), as reflected by the drift rate of the 213.13260694 s period. Using 41 yr of time-series photometry from 1970 November to 2012 January, we determine the rate of change of this period with time to be dP/dt = (5.2 +/- 1.4) x 10(-15) s s(-1) employing the O - C method and (5.45 +/- 0.79) x 10(-15) s s(-1) using a direct nonlinear least squares fit to the entire lightcurve. We adopt the dP/dt obtained from the nonlinear least squares program as our final determination, but augment the corresponding uncertainty to a more realistic value, ultimately arriving at the measurement of dP/dt = (5.5 +/- 1.0) x 10(-15) s s(-1). After correcting for proper motion, the evolutionary rate of cooling of ZZ Ceti is computed to be (3.3 +/- 1.1) x 10(-15) s s(-1). This value is consistent within uncertainties with the measurement of (4.19 +/- 0.73) x 10(-15) s s(-1) for another similar pulsating DA white dwarf, G 117-B15A. Measuring the cooling rate of ZZ Ceti helps us refine our stellar structure and evolutionary models, as cooling depends mainly on the core composition and stellar mass. Calibrating white dwarf cooling curves with this measurement will reduce the theoretical uncertainties involved in white dwarf cosmochronometry. Should the 213.13 s period be trapped in the hydrogen envelope, then our determination of its drift rate compared to the expected evolutionary rate suggests an additional source of stellar cooling. Attributing the excess cooling to the emission of axions imposes a constraint on the mass of the hypothetical axion particle.NSF AST-1008734, AST-0909107Norman Hackerman Advanced Research Program 003658-0252-2009Astronom
