A filtration error in nitrogen determinations     

James L. Leitch  Lorna A. Wells 《Journal of The Franklin Institute》1946,241(1):73-77

Filtration through standard filter papers may introduce a serious error in total and non-protein nitrogen determinations particularly when the procedure involves repeated filtration prior to analysis. Evidence is presented which indicates that some, if not all, of the soluble nitrogen in filter paper is present as ammonia or ammonium salts. This error can be completely eliminated by the use of small sintered glass filters.  相似文献

Using Rhetorical/Relational Goal Theory to Examine College Students’ Impressions of Their Instructors     

Scott A. Myers  James P. Baker  Heather Barone  Stephen M. Kromka  Sara Pitts 《Communication Research Reports》2018,35(2):131-140

Guided by rhetorical/relational goal theory, the purpose of this study was to examine whether students’ impressions of their instructors’ credibility, attraction, and homophily are influenced by four specific rhetorical and relational communication behaviors that instructors use when communicating with their students in the classroom. Participants were 193 undergraduate students enrolled in a variety of introductory communication courses at a large mid-Atlantic university. Using a series of multiple regression analyses, it was found that (a) clarity emerged as the sole indicator of instructor competence, trustworthiness, and task attraction; (b) clarity and confirmation emerged as indicators of goodwill; and (c) humor and confirmation emerged as indicators of social attraction and attitude homophily.  相似文献

Students’ Self-Determination as a Consequence of Instructor Misbehaviors     

James P. Baker  Alan K. Goodboy 《Communication Research Reports》2018,35(1):68-73

The study applied self-determination theory to examine detrimental effects of instructor misbehaviors in the college classroom. Participants were 223 undergraduate students who reported on their instructor’s antagonism and lecture misbehaviors in a course, along with their basic psychological need fulfillment (i.e., autonomy, competence, relatedness) and intrinsic motivation to learn. Results indicated that (a) lecture misbehaviors were more detrimental to students’ competence and relatedness than antagonism misbehaviors; and (b) students’ intrinsic motivation to learn was influenced by students’ basic psychological needs and instructor misbehaviors.  相似文献
