This study used an explanatory mixed methods approach in order to better understand what constitutes cyberbullying behavior through the lens of middle school students. Participants (N=189) were asked respond descriptive vignettes potential situations, increasing severity. A subset students (N=6) also participated semi-structured interviews. Findings suggest perceive online interactions escalate...

Alexis de Tocqueville, a French political scientist and historian who visited America in 1831, is quoted frequently on the distinctions he found between the New and Old Worlds. But some of his other comments highlighted similarities across civilizations: “The village or township is the only association which is so perfectly natural that, wherever a number of men are collected, it seems to const...

The methanolic extract of Flemingia macrophylla roots exhibited significant estrogenic activity in the transgenic plant assay system which was comparable to the activity of soybean extract. Utilizing estrogenic activity-guided fractionation, one new compound, fleminigin, together with 23 known compounds were isolated from F. macrophylla roots' methanolic extract. The structure of the new compou...

Experimental economists are leaving the reservation. They are recruiting subjects in the field rather than in the classroom, using field goods rather than induced valuations, and using field context rather than abstract terminology in instructions. We argue that there is something methodologically fundamental behind this trend. Field experiments differ from laboratory experiments in many ways. ...

The question as to what constitutes a fully calibrated isotope amount ratio measurement still remains a topic of active research. For years, the definitive calibration approach has been by means of synthetic mixtures of highly enriched isotopes with known chemical purity to give gravimetrically defined ratios. This article outlines the core concepts and assumptions of this method and illustrate...

Intramolecular dehydro-Diels-Alder (DDA) reactions are performed affording arylnaphthalene or aryldihydronaphthalene lactones selectively as determined by choice of reaction solvent. This constitutes the first report of an entirely selective formation of arylnaphthalene lactones utilizing DDA reactions of styrene-ynes. The synthetic utility of the DDA reaction is demonstrated by the synthesis o...

A bimolecular chemical reaction in solution constitutes a many-body problem. Even in the pseudounimolecular limit, when one reactant ~say, B! is in large excess over the other ~say, A! there are many B molecules which compete over binding to A. Yet, such effects are generally thought to be of little practical relevance. This impression possibly stems from the intensive study of irreversible dif...

The electrode potential constitutes a dynamical variable whenever an electrode is resistively coupled to the electric circuit. We show that at the nanoscale, the discreteness and stochasticity of an electron transfer event causes fluctuations of the electrode potential that render all elementary electrochemical reactions to be faster on a nanoelectrode than predicted by the macroscopic (Butler-...
