Youth exercise intention and past exercise behavior: examining the moderating influences of sex and meeting exercise recommendations     

Downs DS  Graham GM  Yang S  Bargainnier S  Vasil J 《Research quarterly for exercise and sport》2006,77(1):91-99

The study purposes were to examine: (a) the determinants of exercise intention and past exercise behavior (PEB) using the theories of reasoned action and planned behavior, and (b) the moderating influences of sex and exercise group (meeting or not meeting exercise guidelines). Participants (n = 676 adolescents) completed self-reported measures of their exercise attitude, subjective norm, perceived behavioral control (PBC), intention, and PEB. We found that attitude, subjective norm, and PBC explained 55% of the variance in intention, and intention and PBC explained 51% of the variance in PEB. While we found sex and exercise group differences across the study measures, we did not find evidence of significant moderation. Thus, the theory constructs predicted intention and PEB similarly across sex and exercise groups.  相似文献   

Light-inadequacy of the ultraviolet theory of ionization in the E-layer     

E.F. George 《Journal of The Franklin Institute》1951,252(6):493-500

From the reports of the CRPL, average yearly values of h′_E, h′_F1,f °_E and N_F1, for the months of January, March, June, July, September, and December of the years 1944 to 1949 were computed and plotted against the magnetic latitude. Altogether some 25,000 individual records were averaged. Seven curves were plotted. They showed that: (1) all curves are symmetrical with respect to the magnetic equator; (2) the h′_E, h′_F1, f⁰_E and the N_F, curves all swing up and down as the magnetic latitude, north and south, increases; (3) the h′_E is definitely periodic with constant period and constant amplitude; (4) the h′_E curve rises only slightly (on the average) with latitude. These results appear to be inconsistent with the ultraviolet light theory of ionization.  相似文献   

Buckling of a continuous beam resting on a tensionless elastic foundation     

Christos V. Massalas  George I. Tzivanidis  John T. Katsikadelis 《Journal of The Franklin Institute》1978,306(6):449-455

In this paper, a solution is presented to the buckling problem of a continuous beam resting on a tensionless foundation model that was proposed by Winkler and by Reissner.  相似文献   

Adjacency matrix concepts for the analysis of the interconnection of networks     

William N. Anderson  Richard J. Duffin  George E. Trapp 《Journal of The Franklin Institute》1974,298(1):9-27

A mathematical theory is developed for an imagined device termed a “junctor”. A junctor could be used to interconnect two n-terminal networks giving rise to another n-terminal network. Actually a junctor is itself a simple network with three banks of n-terminals internally connected in some fashion by perfectly conducting wires. Adjacency matrices are formulated to analyze various junctors and their current flows. The main problem treated concerns conditions which would ensure that the junctor operation is associative.  相似文献

PPBS in higher education planning and management: Part II,the university of California experience     

Frederick E. Balderston  George B. Weathersby 《Higher Education》1972,1(3):299-319

Part I provided an overview of PPBS, some discussion of PPBS implementation in the U.S. government, and a review of the arguments for adopting PPBS in postsecondary education and the various kinds of work that have been done toward this end. In part II, we discuss the experience of the University of California with PPBS from 1966 to 1971. Part III, to be published subsequently, will suggest some new departures in model construction and policy analysis which we believe represent a useful spirit in which further development can and should occur, and will also contain some general concluding observations.

Résumé Dans la première partie, publiée antérieurement, on trouvait les principes généraux du PPBS (Program Planning Budgeting Systems) une discussion rapide de la mise en oeuvre du PPBS par les autorités gouvernementals aux Etats-Unis, quelques uns des arguments qui militent en faveur de l'adoption du PPBS dans l'enseignement post-secondaire ainsi que ce qui a été entrepris à cette fin. Dans la deuxième partie, nous soumettons à la discussion ce qu'a été l'expérience de l'Université de Californie en matière de PPBS de 1966 à 1971. La troisième partie, qui sera publiée ensuite, proposera quelques points de départ nouveaux pour la construction du modèle directeur et l'analyse des politiques; nous pensons qui'il s'agit là d'un point de vue utilisable qui peut et devrait donner lieu à de nouveaux développements; cette troisième partie présentera aussi quelques observations générales en forme de conclusion.
