Influence of regression model and incremental test protocol on the relationship between lactate threshold using the maximal-deviation method and performance in female runners

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.     

An analysis of the needs for nonacademic staff and operating funds in a university

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.

How to sustainably increase students’ willingness to protect pollinators

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.

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.     

International research orientation of Swiss universities: self-regulated or politically imposed?

International openness is essential to science in small modern countries. The modernization of Swiss science and economy in the nineteenth century was promoted largely by foreigners: newly founded Swiss universities were staffed to a large extent by foreign professors, but students also came from abroad. Up to the middle of this century, the development of Swiss universities was marked by distinct successive phases of inviting in or shutting out international influence, depending mainly on changes in the political context. The international landscape of knowledge and science since the 1950s has undergone dynamic change. University structures were installed as a reaction to this dynamism. Patterns of international research orientation emerging in different universities and in the disciplinaryfields of business administration, chemistry and history are discussedin a comparative perspective.     

Metacognition and Middle Grade Mathematics Teachers: Supporting Productive Struggle

Communicating mathematical ideas through writing, listening, and verbalizing allows students to think about how they “think” about mathematics. By focusing this communication on a reflection of how one thinks about mathematics, metacognitive writing engages students as mathematicians and learners. In this article we describe a professional development that we implemented with middle grade mathematics teachers focused on metacognitive writing as a tool to support productive struggle in the mathematics classroom. Thus, this practitioner article adds to the knowledge base on how to develop middle grade teachers metacognitive writing through engagement in productive struggle. Recommendations for practice are included.
