Geometric nomenclature and classification of RNA base pairs.

Abstract: Non-Watson‐Crick base pairs mediate specific interactions responsible for RNA‐RNA self-assembly and RNA‐ protein recognition. An unambiguous and descriptive nomenclature with well-defined and nonoverlapping parameters is needed to communicate concisely structural information about RNA base pairs. The definitions should reflect underlying molecular structures and interactions and, thus, facilitate automated annotation, classification, and comparison of new RNA structures. We propose a classification based on the observation that the planar edge-to-edge, hydrogen-bonding interactions between RNA bases involve one of three distinct edges: the Watson‐Crick edge, the Hoogsteen edge, and the Sugar edge (which includes the 29-OH and which has also been referred to as the Shallowgroove edge). Bases can interact in either of two orientations with respect to the glycosidic bonds, cis or trans relative to the hydrogen bonds. This gives rise to 12 basic geometric types with at least two H bonds connecting the bases. For each geometric type, the relative orientations of the strands can be easily deduced. High-resolution examples of 11 of the 12 geometries are presently available. Bifurcated pairs, in which a single exocyclic carbonyl or amino group of one base directly contacts the edge of a second base, and water-inserted pairs, in which single functional groups on each base interact directly, are intermediate between two of the standard geometries. The nomenclature facilitates the recognition of isosteric relationships among base pairs within each geometry, and thus facilitates the recognition of recurrent three-dimensional motifs from comparison of homologous sequences. Graphical conventions are proposed for displaying non-Watson‐Crick interactions on a secondary structure diagram. The utility of the classification in homology modeling of RNA tertiary motifs is illustrated.

Evaluation of three circadian rhythm questionnaires with suggestions for an improved measure of morningness.

Abstract: Circadian rhythms, cyclic fluctuations in many physiological and psychological functions, are thought to influence adjustment to shiftwork. A widely acknowledged individual difference in circadian rhythms, commonly called morningness, indicates preferences associated with morning or evening activities. Various self-report instruments have been developed to measure morningness, although little measurement data have been published for these scales. Because morningness scales are being used to select workers for night shiftwork, psychometric evaluations of these scales are needed. Psychometric assessments of undergraduate responses (N = 501) on three widely used scales indicate internal (interitem) measurement deficiencies in all three. Therefore, a 13-item scale was developed that distills the best items from two of these scales. Relationships between the new composite scale and external criteria are comparable with or stronger than similar relationships between the published scales and external criteria.

Transformational and transactional leadership and salesperson performance

Abstract: This study examines the impact of transformational and transactional leader behaviors on the sales performance and organizational citizenship behaviors of salespeople, as well as the mediating role played by trust and role ambiguity in that process. Measures of six forms of transformational leader behavior, two forms of transactional leader behavior, trust, and role ambiguity were obtained from 477 sales agents working for a large national insurance company. Objective sales performance data were obtained for the agents, and their supervisors provided evaluations of their citizenship behaviors. The findings validate not only the basic notion that transformational leadership influences salespeople to perform “above and beyond the call of duty” but also that transformational leader behaviors actually have stronger direct and indirect relationships with sales performance and organizational citizenship behavior than transactional leader behaviors. Moreover, this is true even when common method biases are controlled. The implications of these findings for future research are discussed.
