This study examined the influence of the regression model and initial intensity of an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and the endurance performance. Sixteen non-competitive, recreational female runners performed a discontinuous incremental treadmill test. The initial speed was set at 7 km · h?1, and increased every 3 min by 1 km · h?1 with a 30-s rest between the stages used for earlobe capillary blood sample collection. Lactate-speed data were fitted by an exponential-plus-constant and a third-order polynomial equation. The lactate threshold was determined for both regression equations, using all the coordinates, excluding the first and excluding the first and second initial points. Mean speed of a 10-km road race was the performance index (3.04 ± 0.22 m · s?1). The exponentially-derived lactate threshold had a higher correlation (0.98 ≤ r ≤ 0.99) and smaller standard error of estimate (SEE) (0.04 ≤ SEE ≤ 0.05 m · s?1) with performance than the polynomially-derived equivalent (0.83 ≤ r ≤ 0.89; 0.10 ≤ SEE ≤ 0.13 m · s?1). The exponential lactate threshold was greater than the polynomial equivalent (P < 0.05). The results suggest that the exponential lactate threshold is a valid performance index that is independent of the initial intensity of the incremental test and better than the polynomial equivalent. 相似文献

Regressions can be used to analyze the relationship between departmental activities and the need for nonacademic staff and operating funds. Support costs are broken into task categories and related to certain basic variables describing the composition and activity of the unit (e.g., FTE academic staff, teaching load). The results are then linked in a total model which predicts the cost for departmental support based on institutional activity variables. Beside the number of students, there are other variables such as the number of fields of study, number of teaching and research staff, and the laboratory equipment. The model is generalizable to many national settings.Presented at the Twentieth Annual Forum of the Institution for Institutional Research, April 1980. 相似文献

The current loss of biodiversity requires efforts to increase awareness of pollinator conservation. An important tool is education which often uses the honeybee (Apis mellifera) as an exemplary organism to reach this goal. Any successful module needs to focus on reducing the perceived danger associated with fear, in order to support the willingness to protect them. Using a quasi-experimental design, we investigated the effectiveness of two educational approaches: one by authentically encountering living animals at a beehive, the other by using a remote online beehive. We monitored secondary school students’ (N = 354) perception of bees with respect to interest, danger and conservation as well as situational emotions (interest, well-being, boredom) during both interventions. In both cases positive effects on perception levels were observed, even when already a high willingness to protect bees existed. Using living animals in educational settings is crucial, especially when students’ situational emotions need targeting. However, we achieved similar intervention results in perception levels using a remote beehive, which therefore constitutes an excellent alternative to raise awareness of the conservation of bees as pollinators when working with living organisms is not possible. 相似文献

To monitor science motivation, 232 tenth graders of the college preparatory level (‘Gymnasium’) completed the Science Motivation Questionnaire II (SMQ-II). Additionally, personality data were collected using a 10-item version of the Big Five Inventory. A subsequent exploratory factor analysis based on the eigenvalue-greater-than-one criterion, extracted a loading pattern, which in principle, followed the SMQ-II frame. Two items were dropped due to inappropriate loadings. The remaining SMQ-II seems to provide a consistent scale matching the findings in literature. Nevertheless, also possible shortcomings of the scale are discussed. Data showed a higher perceived self-determination in girls which seems compensated by their lower self-efficacy beliefs leading to equality of females and males in overall science motivation scores. Additionally, the Big Five personality traits and science motivation components show little relationship. 相似文献

Der Beitrag stellt AutoFocus vor, einen Werkzeugprototyp zur Entwicklung verteilter, eingebetteter Systeme auf der Grundlage formaler Techniken. AutoFocus unterstützt die Systementwicklung mit integrierten, im wesentlichen graphischen Beschreibungstechniken, mit deren Hilfe sowohl unterschiedliche Sichten als auch verschiedene Abstraktionsebenen eines Systems beschrieben werden. Um konsistente und vollst?ndige Beschreibungen sicherzustellen, bietet AutoFocus die M?glichkeit, Konsistenzbedingungen zu formulieren und Systembeschreibungen daraufhin zu überprüfen. Aus ausführbaren Spezifikationen k?nnen Prototypen des entwickelten Systems erzeugt werden und in einer Simulationsumgebung ausgeführt und visualisiert werden. Zur formalen Verifikation von Systemeigenschaften verfügt AutoFocusüber Anbindungen an Modellprüfungswerkzeuge wie -cke oder SMV. 相似文献

近代以来的历史是一部人的异化史,近代以来的技术进步是存在遗忘自身的过程。海德格尔和马克思认为,这是一个不可避免的过程,是人类进步必须付出的代价。但是,从东方的儒家、道家和佛教所组成的"元儒家"的思想出发,我们可以证明,资本主义和帝国主义及其带来的灾难并不拥有必然性的光环。从另一个角度看,从教条主义中解放出来的马克思主义和海德格尔的关于存在之思可以与"元儒家"共同承担起对当代社会的批判以及对未来社会的建构的使命,并因此而成为"元儒家"的核心要素。 相似文献

Acquisition of conceptual knowledge is a central aim in science education. In this study we monitored an interdisciplinary
hypermedia assisted learning unit on hibernation and thermodynamics based on cooperative learning. We used concept mapping
for the assessment, applying a pre-test/post-test design. In our study, 106 9th graders cooperated by working in pairs (n = 53) for six lessons. As an interdisciplinary learning activity in such complex knowledge domains has to combine many different
aspects, we focused on long-term knowledge. Learners working cooperatively in dyads constructed computer-supported concept
maps which were analysed by specific software. The data analysis encompassed structural aspects of the knowledge corresponding
to a target reference map. After the learning unit, the results showed the acquisition of higher-order domain-specific knowledge
structures which indicates successful interdisciplinary learning through the hypermedia learning environment. The benefit
of using a computer-assisted concept mapping assessment for research in science education, and in science classrooms is considered. 相似文献
