Im Universitätspersonalrecht findet sich eine Reihe von zeitlichen und systemischen Schnittstellen hinsichtlich des Anspruchs auf Abfertigung. Als mögliche Rechtsgrundlagen für die Abfertigung kommen das AngG, das BMSVG, das VBG, das BDG, das UniAbgG und der Universitäten-Kollektivvertrag in Frage. Diese Anspruchsgrundlagen wechseln nicht nur entsprechend der Art des Arbeitsverhältnisses, sondern stehen auch in Relation zum In-Kraft-Treten des UG und des Universitäten-KV. In Summe ergibt dies eine Fülle von Problemlagen, die der Gesetzgeber keiner eindeutigen Lösung zugeführt hat. 相似文献

Gross dissection for demonstrating anatomy of the human pelvis has traditionally involved one of two approaches, each with advantages and disadvantages. Classic hemisection in the median plane through the pelvic ring transects the visceral organs but maintains two symmetric pelvic halves. An alternative paramedial transection compromises one side of the bony pelvis but leaves the internal organs intact. The authors propose a modified technique that combines advantages of both classical dissections. This novel approach involves dividing the pubic symphysis and sacrum in the median plane after shifting all internal organs to one side. The hemipelvis without internal organs is immediately available for further dissection of the lower limb. The hemipelvis with intact internal organs is ideal for showing the complex spatial relationships of the pelvic organs and vessels relative to the intact pelvic floor.

In this paper, two methodological perspectives are used to elaborate on the value of cognitive load theory (CLT) as a scientific
theory. According to the more traditional critical rationalism of Karl Popper, CLT cannot be considered a scientific theory
because some of its fundamental assumptions cannot be tested empirically and are thus not falsifiable. According to the structuralist
view of theories introduced by Joseph D. Sneed, a theory may be considered scientific even if it comprises nontestable fundamental
assumptions. Rather, the scientific value of a theory results from the holistic empirical content of the overall theory net
built around fundamental assumptions and from the successful applications of this theory net to explain and predict empirical
findings. This latter view is helpful to explicate some implicit methodological assumptions of CLT research and to avoid the
potential circularity of CLT’s fundamental assumptions. Additionally, the structuralist view of theories can be directly used
to derive a research agenda for the future development of CLT. 相似文献

IntroductionIt is common for patients to switch between several healthcare providers. In this context, the long-term follow-up of medical conditions based on laboratory test results obtained from different laboratories is a challenge. The measurement uncertainty in an inter-laboratory context should also be considered in data mining research based on routine results from randomly selected laboratories. As a proof-of-concept study, we aimed at estimating the inter-laboratory reference change value (IL-RCV) for exemplary analytes from publicly available data on external quality assessment (EQA) and biological variation.Materials and methodsExternal quality assessment data of the Reference Institute for Bioanalytics (RfB, Bonn, Germany) for serum creatinine, calcium, aldosterone, PSA, and of whole blood HbA1c from campaigns sent out in 2019 were analysed. The median CVs of all EQA participants were calculated based on 8 samples from 4 EQA campaigns per analyte. Using intra-individual biological variation data from the EFLM database, positive and negative IL-RCV were estimated with a formula based on log transformation under the assumption that the analytes under examination have a skewed distribution.ResultsWe estimated IL-RCVs for all exemplary analytes, ranging from 13.3% to 203% for the positive IL-RCV and - 11.8% to - 67.0% for the negative IL-RCV (serum calcium - serum aldosterone), respectively.ConclusionExternal quality assessment data together with data on the biological variation – both freely available – allow the estimation of inter-laboratory RCVs. These differ substantially between different analytes and can help to assess the boundaries of interoperability in laboratory medicine. 相似文献

Environmental issues such as climate change are becoming ever more important in today’s societies and politics. Information is spread by the media, for example, via the Internet or information brochures, employing different representational styles (e.g. sensational vs. neutral styles, emphasis of human vs. natural causes). We investigated the effects of such differences in presentation when informing about local impacts of climate change – more specifically about invasive species – on perceived risk, emotions, and learning. Seventy-two students at a German university read five brochures about the local effects of climate change and invasive species. They rated their perceived risk and emotions and worked on learning outcome tests. As expected, the sensational style led to higher perceived risk and stronger negative emotions than the neutral style. In addition, our results reveal a potential dilemma for environmental education: while a sensational style enhanced general learning outcomes, it seemed to lead to quite a negative and one-sided view about climate change and invasive species. 相似文献

The present paper reports on an empirical study which investigated learning with text and animations in the science classroom. In a 2?×?2 design the presence of multimedia learning material instruction (text only vs. text + animations) as well as the modality of the explanatory text (spoken vs. written) were tested. Prior to learning, students’ motivation to learn was assessed as a continuous factor. Recall and transfer were assessed immediately after learning. The results show better recall of information for learners with multimedia materials, providing the animations were accompanied by spoken text. However, in contrast to the positive effects of domain-specific motivation this multimedia effect was not evident for transfer. The effects of multimedia design were independent of motivation. Implications for future studies are discussed. 相似文献

Multiple studies have shown benefits of problem-solving prior to instruction (cf. Productive Failure, Invention) in comparison to direct instruction. However, students’ solutions prior to instruction are usually erroneous or incomplete. In analogy to guided discovery learning, it might therefore be fruitful to lead students towards the discovery of the canonical solution. In two quasi-experimental studies with 104 students and 175 students, respectively, we compared three conditions: problem-solving prior to instruction, guided problem-solving prior to instruction in which students were led towards the discovery of relevant solution components, and direct instruction. We replicated the beneficial effects of problem-solving prior to instruction in comparison to direct instruction on posttest items testing for conceptual knowledge. Our process analysis further revealed that guidance helped students to invent better solutions. However, the solution quality did not correlate with the posttest results in the guided condition, indicating that leading students towards the solution does not additionally promote learning. This interpretation is supported by the finding that the two conditions with problem-solving prior to instruction did not differ significantly at posttest. The second study replicated these findings with a greater sample size. The results indicate that different mechanisms underlie guided discovery learning and problem-solving prior to instruction: In guided discovery learning, the discovery of an underlying model is inherent to the method. In contrast, the effectiveness of problem-solving prior to instruction does not depend on students’ discovery of the canonical solution, but on the cognitive processes related to problem-solving, which prepare students for a deeper understanding during subsequent instruction. 相似文献

The aim of this study was to investigate the development of metacognitive strategy knowledge (MSK) during schooling at the upper secondary education level and to examine its relation with individual student characteristics. This longitudinal study with two measurement points analyzed a sample of students in grades 10 and 11 from 19 schools preparing students for university in Switzerland. The findings showed no development of MSK within a single year of school. Individual differences appeared in the level and the change of MSK over time. Female students as well as students with higher SES displayed higher MSK than male students and students with lower SES at the first measurement point. Furthermore, SES predicted changes in MSK over time. Between learning motivation and MSK as well as self-efficacy and MSK, high correlations were found at t1. Neither learning motivation nor self-efficacy had an effect on the change of MSK over time. The results show that there is still substantial potential for MSK development at the upper secondary education level. Implications for education and further studies are discussed. 相似文献

Although school development can be viewed as an emerging responsibility of teachers, special needs education in Germany does not leave sufficient room for non-teaching tasks, leading to a knowledge gap in the professionalisation of pre-service teachers with regard to school development upon entering the profession. This study focused on the preparedness of pre-service teachers in school development as a professional task at the end of their initial teacher training. The respondents of the interview study are 12 pre-service teachers enrolled at master level in special educational needs at a German university. The findings of the study report on the marginal situatedness of school development in the curriculum, the associated understanding of pre-service teachers of school development and their low assessment of the relevance of school development within special needs education. The study closes with practical recommendations on how to tackle the low level of preparedness for school development tasks in German teacher education. 相似文献
