The first American scientific journal devoted specifically to the study of animal behavior was the Journal of Animal Behavior, founded by Robert M. Yerkes in 1911. An examination of Yerkes's efforts to establish such a journal underscores the precariousness of animal behavior studies (and journal publications) in this period. The analysis of the different kinds of articles published by psychologists and zoologists in the Journal of Animal Behavior shows furthermore that already by the second decade of the twentieth century psychologists and zoologists were pursuing quite distinct programs of research in terms of their choices of animal subjects, topics of investigation, and research methodologies. The relation of the Journal of Animal Behavior to its successor, the Journal of Comparative Psychology, is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

The Center for the History of Psychology (CHP) was founded as the Archives of the History of Psychology (AHAP) in 1965 at The University of Akron in Akron, Ohio. In 2010, the Board of Trustees at The University of Akron approved the renaming of the Archives as the Center for the History of Psychology to reflect this increased scope of activities and offerings. The AHAP continues to operate as a unit with the larger Center. This article discusses the history of the CHP, its collections, research and accessibility initiatives, education and public programming initiatives, and the many ongoing projects and future plans for the CHP.

For a two‐strand slab caster and a tundish capacity of 50 t the transition zone between two heats of different chemical composition was experimentally defined. The distribution of various elements was measured. The transition curves also show the penetration depth of the casting stream using a bifurcated submerged nozzle. This is basic information for the calculation of the mixing zone. Knowledge of the permissible composition ranges permits optimisation of the usable length of the strand. The impact of ladle change on oxide cleanness is analysed as well.  相似文献
