Der Beitrag thematisiert jugendliche Orientierungsmuster zur Ausgestaltung der Lebensphase Jugend und deren Ver?nderung über die Zeit. Diese entstehen im komplexen Zusammenhang von wahrgenommenen Ressourcen, Einstellungen und Erwartungen Jugendlicher im Hinblick auf die Anforderung der Bew?ltigung von Entwicklungsaufgaben. Zur Abbildung dieser Muster wird auf zwei zentrale Dimensionen zurückgegriffen: auf Entfaltungsorientierung, die den Moratoriumsgedanken, und Entwicklungsorientierung, die den transitiven Charakter der Jugendphase widerspiegelt. Aus der Kombination der Orientierungen Entwicklung und Entfaltung im Anschluss an die Verknüpfung des Transitions-und Moratoriumsgedankens lassen sich vier Typen ableiten. Die Zugeh?rigkeit zu einem Typ ist nicht als statisch zu fassen, sondern ver?ndert sich entsprechend der zunehmenden Bew?ltigung von Entwicklungsaufgaben. Die Ergebnisse veranschaulichen die weitreichende Bedeutung beruflicher Orientierungen Jugendlicher im Zusammenhang mit dem bevorstehenden übergang in den Beruf, die gleichsam Auswirkungen für den gesamten Komplex jugendlicher Orientierungsmuster (Typen) zur Gestaltung der Jugendphase zeitigen.  相似文献

Since footwear flexibility impacts functional design factors, numerous studies have investigated footwear bending stiffness. However, the various methods used to measure footwear bending stiffness have some limitations. Hence, the scope of this study was to develop and quantify the reliability of a novel test set-up for measuring footwear bending stiffness. A test set-up consisting of a hydraulic testing machine, a bending apparatus and a fixation unit was created that fulfilled the requirements specified in the initial phase of the study. The test set-up was evaluated by testing 15 different boots in three series of measurements. Bending stiffness of the boots ranged from 0.61 ± 0.03 to 2.38 ± 0.08 Nm/°. Two-way analysis of variance test yielded that the test set-up enabled the reliable measurement of footwear bending stiffness. Relative measurement uncertainty ranged from 1.3 to 6.1 %.  相似文献

Experiment 1 compared the acquisition of a feature-positive and a feature-negative discrimination in humans. In the former, an outcome was signaled by two stimuli together, but not by one of these stimuli alone. In the latter, the outcome was signaled by one stimulus alone, but not by two stimuli together. Using a within-group design, the experiment revealed that the feature-positive discrimination was acquired more readily than the feature-negative discrimination. Experiment 2 tested an explanation for these results, based on the Rescorla-Wagner theory, by examining how novel discriminations, based on a combination of a feature-positive and a feature-negative discrimination, were solved. The results did not accord with predictions from the theory. Alternative explanations for the results are considered.  相似文献

Age-publishing profiles are estimated for four fields of science using data from the 1977 Survey of Doctorate Recipients. The five measures of publishing activity used allow for analysis of the sensitivity of the age-publishing relationship to output measure. Results are presented separately for graduate faculty and faculty at nongraduate departments. Although age is found to be a fairly weak predictor of performance, in physics and earth science older scientists publish less than their youngest peers and in physiology and biochemistry older scientists publish less than their middle-aged colleagues. Given the time frame of the data, the results suggest that the graying of America's scientific community was accompanied with slowed rates of research in higher education.  相似文献

This paper attempts to engage the field in a discussion about what mathematics is needed for students to engage in society, especially with an increase in technology and digitalization. In this respect, mathematics holds a special place in STEM as machines do most of the calculations that students are taught in K-12. We raise questions about what mathematical proficiency means in today’s world and what shifts need to be made in both content and pedagogy to prepare students for 21st Century Skills and mathematical reasoning.  相似文献
