Yet, the assessment of methods for network construction is often uncertain. Random resampling simulations can aid to assess methods, provided synthetic data exists for reliable network construction. Objectives: We implemented a new Monte Carlo algorithm to create simulated data for network reconstruction, tested the influence of adjusted parameters and used simulations to select a method for network model estimation based on real-world data. We hypothesized, that reconstructs based on Monte Carlo data are scored at least as good compared to a benchmark. Methods: Simulated data was generated in R using the Monte Carlo algorithm of the mcgraph package. Benchmark data was created by the huge package. Networks were reconstructed using six estimator functions and scored by four classification metrics. For compatibility tests of mean score differences, Welch’s t-test was used. Network model estimation based on real-world data was done by stepwise selection. Samples: Simulated data was generated based on 640 input graphs of various types and sizes. The real-world dataset consisted of 67 medieval skeletons of females and males from the region of Refshale (Lolland) and Nordby (Jutland) in Denmark. Results: Results after t-tests and determining confidence intervals (CI95%) show, that evaluation scores for network reconstructs based on the mcgraph package were at least as good compared to the benchmark huge. The results even indicate slightly better scores on average for the mcgraph package. Conclusion: The results confirmed our objective and suggested that Monte Carlo data can keep up with the benchmark in the applied test framework. The algorithm offers the feature to use (weighted) un- and directed graphs and might be useful for assessing methods for network construction.

Our paper develops a new method for measuring strategic-uncertainty attitudes and distinguishing them from risk and ambiguity attitudes. We vary the source of uncertainty (whether strategic or not) across conditions in a ceteris paribus manner. We elicit certainty equivalents of participating in two strategic 2x2 games (a stag-hunt and a market-entry game) as well as certainty equivalents of related lotteries that yield the same possible payoffs with exogenously given probabilities (risk) and lotteries with unknown probabilities (ambiguity). We provide a structural model of uncertainty attitudes that allows us to measure a preference for or an aversion against the source of uncertainty, as well as optimism or pessimism regarding the desired outcome. We document systematic attitudes towards strategic uncertainty that vary across contexts. Under strategic complementarity [substitutability], the majority of participants tend to be pessimistic [optimistic] regarding the desired outcome. However, preferences for the source of uncertainty are distributed around zero.

When measured at short intervals, children’s growth shows characteristic patterns that can be of great importance for clinical purposes. Objective: To study whether measuring height on a daily basis using an APP is practicable and user-friendly. Methods: Recruitment took place via Snowball Sampling. Thirteen out of 14 contacted families signed up for a study period of 12 weeks with altogether 22 healthy children aged 3 to 13 years (response rate 93%). The study started with a visit to the family home for the setup of the measurement site, conventional height measuring and initial training of the new measurement process. Follow-up appointments were made at four, eight and 12 weeks. The children’s height was measured at daily intervals at their family homes over a period of three months. Results: The parents altogether recorded 1704 height measurements and meticulously documented practicability and problems when using the device. A 93% response rate in recruitment was achieved by maintaining a high motivation within the families. Contact with the principal investigator was permanently available, including open communication, personal training and attendance during the appointments at the family homes. Conclusion: Measuring height by photographic display is interesting for children and parents and can be used for height measurements at home. A positive response rate of 13 out of 14 families with altogether 22 children highlights feasible recruitment and the high convenience and user-friendliness of daily APP-supported height measurements. Daily APP measurements appear to be a promising new tool for longitudinal growth studies.

Within these societies, the acceptance of suffering may also be higher, which leads to different priorities of conflict resolution approaches. Furthermore, this chapter deals with the question of whether the current understanding of wars and the nature of conflict change the basis of established conflict theories. These theoretical approaches are then applied in Sierra Leone as a non-Western negotiation scenario.

Die vielfältigen Ziele schließen den Kompetenzerwerb entsprechend den KMK-Vorgaben sowie die Berufswahlüberprüfung ein. Forschungsbefunde deuten jedoch darauf hin, dass nicht alle erhoff ten Ziele in Schulpraktika auch tatsächlich erreicht werden. Die konkreten Lernsituationen im Praxissemester standen hingegen bisher wenig im Fokus. Um dies aufzugreifen, interviewten wir für die vorliegende Studie N = 7 Lehramtsstudierende unmittelbar nach Abschluss ihres Praxissemesters zu den von Ihnen wahrgenommenen Lernerfolgen und den Lerngelegenheiten, in denen sie diese erzielten. Die Ergebnisse zeigen, dass die Studierenden glauben, vor allem ihre Unterrichts-Kompetenzen weiterentwickelt und sich als Lehrkraft sowie ihre Lehrer:innenpersönlichkeit kennengelernt zu haben. Als zentrale Lerngelegenheit benennen sie insbesondere den Austausch mit den Mentorinnen und Mentoren. N2 - The student teaching semester, allowing the pre-service teachers to spend several months at a school, have become an important part of practical teacher training during university studies. The manifold aims include capacity building in teacher competences as well as providing an opportunity to review one’s career choice. At the same time, current studies show that practical teacher training tends to leave many of its aims unfulfilled. So far, however, the research focus was not on learning opportunities during the student teaching semester. To find out how pre-service teachers judge learning outcomes and opportunities, we interviewed seven pre-service teachers after the end of their student teaching semester. The results show that the pre-service teachers believe they developed their teaching competences and got to know themselves as „teachers“. To them, talking to their mentor teacher presented itself as the most meaningful learning opportunity.

Bereits im Potsdamer Modell der Lehrerbildung (1993) sind sie festgehalten, seit der Integration des Schulpraktikums (Praxissemesters) 2008 absolvieren alle Potsdamer Lehramtsstudierenden fünf Pflichtpraktika. Während die Ziele der Praktika klar beschrieben sind, sind die tatsächlichen Lernerfolge nicht immer klar – ebenso wenig, wie die Begleitung der Praktika aussehen muss, um die Studierenden bestmöglich zu unterstützen. Auch die Integration in weitere Lehrveranstaltungen des Studiums ist ein noch offenes Feld, das weiterer Betrachtung verdient. Die unterschiedliche Ausrichtung der Potsdamer Praktika, Perspektivwechsel im Orientierungs-/Integriertem Eingangspraktikum, Selbstreflektion im Praktikum in pädagogisch-psychologischen Handlungsfeldern, Unterricht als Profession in den Fachdidaktischen Tagespraktika, Anwendung von Diagnostik im psychodiagnostischen Praktikum und die Synthese all dessen im Schulpraktikum, bieten dafür zahlreiche Ansatzpunkte. Schulpraktika sind nicht nur ein zentraler und von Studierenden hoch geschätzter Bestandteil des Studiums, sondern werden auch zunehmend für die Bildungsforschung interessant. Fragen nach der Kompetenzentwicklung, Selbsteinschätzungen und der Entwicklung der Reflexionsfähigkeit von Studierenden stehen dabei ebenso im Fokus wie die Einschätzung der universitären Begleitung und der Einbindung ins weitere Studium. Der vorliegende Band versammelt Studien von Wissenschaftlerinnen und Wissenschaftler der Universität Potsdam, die die fünf Pflichtpraktika im Lehramtsstudium unter unterschiedlichen Blickwinkel beforschen. Besonders hervorzuheben ist, dass die Wissenschaftlerinnen und Wissenschaftler aus unterschiedlichen Disziplinen stammen und somit die Praktika mit verschiedenen Instrumenten und aus unterschiedlichen Blickwinkeln betrachten. Die präsentierten Ergebnisse bilden eine gute Grundlage, um die Praktika in Potsdam und an anderen Standorten weiterzuentwickeln.

They are commonly applied to examine the effectiveness of classroom-based interventions to reduce problem behavior in schools. At the same time, there is no consensus on good design characteristics of single-case experimental designs when dealing with behavioral problems in schools. Moreover, specific challenges arise concerning appropriate approaches to analyzing behavioral data. Our study addresses the interplay between the test power of piecewise regression analysis and important design specifications of single-case research designs. Here, we focus on the influence of the following specifications of single-case research designs: number of measurement times, the initial frequency of the behavior, intervention effect, and data trend. We conducted a Monte-Carlo study. First, simulated datasets were created with specific design conditions based on reviews of published single-case intervention studies. Following, data were analyzed using piecewise Poisson-regression models, and the influence of specific design specifications on the test power was investigated. Our results indicate that piecewise regressions have a high potential of adequately identifying the effects of interventions for single-case studies. At the same time, test power is strongly related to the specific design specifications of the single-case study: Few measurement times, especially in phase A, and low initial frequencies of the behavior make it impossible to detect even large intervention effects. Research designs with a high number of measurement times show robust power. The insights gained are highly relevant for researchers in the field, as decisions during the early stage of conceptualizing and planning single-case experimental design studies may impact the chance to identify an existing intervention effect during the research process correctly.

T2 - CEPA Discussion Papers N2 - The self-employed faced strong income losses during the Covid-19 pandemic. Many governments introduced programs to financially support the self-employed during the pandemic, including Germany. The German Ministry for Economic Affairs announced a €50bn emergency-aid program in March 2020, offering one-off lump-sum payments of up to €15,000 to those facing substantial revenue declines. By reassuring the self- employed that the government ‘would not let them down’ during the crisis, the program had also the important aim of motivating the self-employed to get through the crisis. We investigate whether the program affected the confidence of the self-employed to survive the crisis using real-time online-survey data comprising more than 20,000 observations. We employ propensity score matching, making use of a rich set of variables that influence the subjective survival probability as main outcome measure. We observe that this program had significant effects, with the subjective survival probability of the self- employed being moderately increased. We reveal important effect heterogeneities with respect to education, industries, and speed of payment. Notably, positive effects only occur among those self-employed whose application was processed quickly. This suggests stress-induced waiting costs due to the uncertainty associated with the administrative processing and the overall pandemic situation. Our findings have policy implications for the design of support programs, while also contributing to the literature on the instruments and effects of entrepreneurship policy interventions in crisis situations.

Welche Faktoren für die Entwicklung von Überzeugungen in Praxisphasen von Bedeutung sind, ist bislang aber nur unzureichend erforscht. In Interviews haben wir N = 16 Studierende befragt, welche Lerngelegenheiten für die Entwicklung ihrer Überzeugungen im Praxissemester eine Rolle spielten. Dabei konnten wir mittels Inhaltsanalyse vier übergeordnete Faktoren identifizieren: die universitäre Lernbegleitung, die Mentorinnen und Mentoren, die Schülerinnen und Schüler und die Reflexion eigener Unterrichtserfahrungen. Den Faktoren wurden untergeordnete Faktoren (z. B. Hospitationen durch Universitätsdozierende) zugeordnet und es wird dargestellt, warum und unter welchen Umständen diese Lerngelegenheiten für die Entwicklung der Überzeugungen aus Studierendensicht relevant sind. N2 - Beliefs about teaching and learning are part of a teacher’s professional competence. They should, thus, already be considered in teacher preparation as they can evolve, especially in the context of field experience. However, research on the factors that influence the development of teachers’ beliefs during school placement is sparse. We asked N = 16 preservice teachers which learning opportunities they considered relevant for the development of their beliefs in the Praxissemester. Using qualitative content analysis, we identified four main factors: university support, mentors in schools, pupils, and reflection on teaching experiences. We assigned subordinate factors (e. g. accompanying seminars) to the main factors. Subsequently, we describe why and under which circumstances these learning opportunities are relevant for the development of beliefs from the preservice teachers’ point of view.
