Influencing a Swift Trust for Elevating Communications of a Virtual Learning Community

The reduced range of online communication means that less information is available for the parties in a communication to acquire an accurate meaning of words, phrases, or concepts in an exchange process. In online communication, encoded emotional information is often subtle and difficult to interpret with any degree of accuracy; this interpretation is even more difficult in academic discussions that are lacking in emotion. The resulting misunderstandings contribute to a degree of uncertainty and confusion with some students, and to full-blown conflict with others. Uncertainty is problematic because it can inhibit or altogether collapse a conventional trust perception. The most valuable communications, therefore, develop on a foundation of trust. This study was designed to explore swift trust, a lesser form of trust that can form instantly from the initial communications expressed in a community. A swift trust perception can bridge social development and allow communicants to ignore the communication and environmental challenges that impede a conventional form of trust from developing for virtual communities. This quantitative study utilized multiple regression analysis to predict relationships between the predictive variables and examine the criterion variables in focus. The multiple regression analysis was used to interpret the survey data and provide insight into the trust-inducing potential of a fragile swift trust perception for elevating online discussions to a higher level

Photometry of GSC 762-110, a new triple-mode radially pulsating star

Stars pulsating in three radial modes are very rare; only three examples are known in the Galaxy. These stars are very useful since their periods may be measured very precisely, and this will constrain the global stellar parameters and the models of the star's interior. The purpose of this paper is to present a new example of the class of triple-mode radial pulsators. A search for candidate multi-mode pulsators was carried out in public survey data. Time-series photometry of one of the candidates, GSC 762-110, was performed. GSC 762-110 was found to be a triple-mode radial pulsator, with a fundamental period of 0.1945d and period ratios of 0.7641 and 0.8012. In addition two non-radial modes were found, for which the amplitude has diminished considerably over the last few years.Comment: Accepted for publication in Astronomy & Astrophysic

Population Structure and Biomass of Some Common Snakes in Central North America

Samples of 113 to 1762 individuals were obtained from local populations of 11 common species of snakes in Kansas and one in Oklahoma. An age-size correlation was established for each species from the records of marked individuals that were recaptured. Each snake in the samples was tentatively allocated on the basis of its snout-vent length (or alternatively on its rattle string in Crotalus). Local populations were interpreted to consist of from eight (Thamnophis sirtalis) to 18 (Crotalus atrox) annual age cohorts. In samples of Coluber constrictor, Nerodia sipedon, and Thamnophis sirtalis, females outnumbered males and attained larger mean size. In Nerodia and Thamnophis, females survived longer than males; in Coluber the sexes were similar in longevity. In Agkistrodon contortrix, Crotalus atrox, C. horridus, C. viridis, Elaphe obsoleta, Lampropeltis calligaster, L. triangulum, and Pituophis catenifer, males outnumbered females, grew larger,-and survived longer on average. In Diadophis punctatus, males were more numerous than females and survived longer, but females had average larger size. In each species sample, first-year young were poorly represented, with only 4 to 46% of expected numbers, and it seemed that their cryptic behavior and markings caused them to be overlooked much more often than adults, regardless of the method of sampling. Biomasss calculations indicated that Diadophis punctatus constituted nearly half of the total, with Coluber constrictor, Elaphe obsoleta, Thamnophis sirtalis, Lampropeltis calligaster, and Agkistrodon contortrix making up from 18% to 5%, whereas Crotalus horriidus, Lampropeltis triangulum, Nerodia sipedon, and Pituophis catenifer made up only very small percentage

Evidence of a structural anomaly at 14 K in polymerised CsC60

We report the results of a high-resolution synchrotron X-ray powder diffraction study of polymerised CsC$_{60}$ in the temperature range 4 to 40 K. Its crystal structure is monoclinic (space group I2/m), isostructural with RbC$_{60}$. Below 14 K, a spontaneous thermal contraction is observed along both the polymer chain axis, $a$ and the interchain separation along [111], $d_1$. This structural anomaly could trigger the occurrence of the spin-singlet ground state, observed by NMR at the same temperature.Comment: 8 pages, 5 figures, submitte

Cross modal perception of body size in domestic dogs (Canis familiaris)

While the perception of size-related acoustic variation in animal vocalisations is well documented, little attention has been given to how this information might be integrated with corresponding visual information. Using a cross-modal design, we tested the ability of domestic dogs to match growls resynthesised to be typical of either a large or a small dog to size- matched models. Subjects looked at the size-matched model significantly more often and for a significantly longer duration than at the incorrect model, showing that they have the ability to relate information about body size from the acoustic domain to the appropriate visual category. Our study suggests that the perceptual and cognitive mechanisms at the basis of size assessment in mammals have a multisensory nature, and calls for further investigations of the multimodal processing of size information across animal species
