Guidance in eastern Europe: from ideological formation to an emerging service model     

Victor J. Drapela 《International journal for the advancement of counseling》1987,10(3):209-224

This article analyzes major changes that have occurred in east-European guidance over the past decades. The emphasis has gradually shifted from purely ideological concerns to an interest in serving the needs of individuals. Whereas in the initial stage structural uniformity was of great importance, current views accept a degree of diversification in guidance services on the basis of regional needs and sociocultural traditions. Tangible differences seem to exist between guidance strategies that are prevalent in the Soviet Union and in certain areas of east-central Europe.University of South Florida  相似文献

Impacts on college administration: Management information systems and management by objectives systems     

J. Victor Baldridge 《Research in higher education》1979,10(3):263-282

Forty-nine private liberal arts colleges received grants from the Exxon Education Foundation to improve their management procedures. Research was conducted to determine the success of the management innovations, and the impact of the process on the college's management. About half the colleges had innovations that completely failed because of staff turnover, inadequate administrative support, or other causes. In the other, more successful group the research showed a number of positive impacts of the projects: (1) Management Information Systems were quite useful in providing comprehensive management data, in analyzing hot spots of trouble, and increasing sophistication of administrators; (2) Management by Objectives projects increased administrative and faculty morale and insured more adequate planning, and (3) combinations of both MIS and MBO projects produced the strongest positive impact. Both types of projects, however, failed to link planning with budgeting, a major flaw.  相似文献

On rectangular systems of differential equations and their application to circuit theory     

Victor Lovass-Nagy  David L. Powers 《Journal of The Franklin Institute》1975,299(6):399-407

A system of differential equations A(d/dt) x = Bx+f, along with the initial condition x(0) = k, is considered where A and B are m x n matrices. Generalized inverses of the matrix A are used to derive algebraic conditions for the existence and uniqueness of a solution. An example is presented to illustrate application of the results to circuit theory.  相似文献   

A comparison between elemental and compound training of cues in retrospective revaluation     

Martha Escobar  Oskar Pineño  Helena Matute 《Learning & behavior》2002,30(3):228-238

Associative learning theories assume that cue interaction and, specifically, retrospective revaluation occur only when the target cue is previously trained in compound with the to-be-revalued cue. However, there are recent demonstrations of retrospective revaluation in the absence of compound training (e.g., Matute &; Pineño, 1998a, 1998b). Nevertheless, it seems reasonable to assume that cue interaction should be stronger when the cues are trained together than when they are trained apart. In two experiments with humans, we directly compared compound and elemental training of cues. The results showed that retrospective revaluation in the elemental condition can be as strong as and, sometimes, stronger than that in the compound condition. This suggests that within-compound associations are not necessary for retrospective revaluation to occur and that these effects can possibly be best understood in the framework of general interference theory.  相似文献   

Assessing dialogic argumentation in online environments to relate structure,grounds, and conceptual quality     

Douglas B. Clark  Victor Sampson 《科学教学研究杂志》2008,45(3):293-321

The national science standards, along with prominent researchers, call for increased focus on scientific argumentation in the classroom. Over the past decade, researchers have developed sophisticated online science learning environments to support these opportunities for scientific argumentation. Assessing the quality of dialogic argumentation, however, has proven challenging. Existing analytic frameworks assess dialogic argumentation in terms of the nature of students' discourse, formal argumentation structure, interactions, and epistemic forms of reasoning. Few frameworks, however, connect these assessments to conceptual quality. We present an analytic framework for assessing argumentation in online science learning environments that relates levels of opposition with discourse moves, use of grounds, and conceptual quality. We then apply the proposed framework to students' dialogic argumentation within a representative online science learning environment to investigate the framework's potential affordances as well as to assess issues of reliability and appropriateness. The results suggest that the framework offers significant affordances and that it also offers high interrater reliability for trained coders. The applicability of the framework for offline contexts and future extensions of the framework are discussed in light of these results. © 2007 Wiley Periodicals, Inc.
