For each evaluation method, we identify progress and milestones to date, and draw out lessons learnt as well as challenges remaining. We find that each evaluation method has distinctive strengths, as well as constraints on its application. We use these insights to propose a systematic evaluation framework combining multiple methods to establish the appropriateness, interpretability, credibility, and relevance of process-based IAMs as useful scientific tools for informing climate policy.

The agency theory is applied within the framework of rational-choice institutionalism to study the institutional arrangements that surround two different money allocation mechanisms, identify the incentives they create for the behavior of individual actors in the field, and examine how these then transfer into measurable differences in managerial quality of development aid projects. In this work, project management quality is seen as an important determinant of the overall project success. For data-gathering purposes, the German development agency, the Gesellschaft f{\"u}r Internationale Zusammenarbeit (GIZ), is used due to its unique way of work. Whereas the majority of projects receive funds via direct-award mechanism, there is a commercial department, GIZ International Services (GIZ IS) that has to compete for project funds. The data concerning project management practices on the GIZ and GIZ IS projects was gathered via a web-based, self-administered survey of project team leaders. Principal component analysis was applied to reduce the dimensionality of the independent variable to total of five components of project management. Furthermore, multiple regression analysis identified the differences between the separate components on these two project types. Enriched by qualitative data gathered via interviews, this thesis offers insights into everyday managerial practices in development cooperation and identifies the advantages and disadvantages of the two allocation mechanisms. The thesis first reiterates the responsibility of donors and implementers for overall aid effectiveness. It shows that the mechanism of competitive contracting out leads to better oversight and control of implementers, fosters deeper cooperation between the implementers and beneficiaries, and has a potential to strengthen ownership of recipient countries. On the other hand, it shows that the evaluation quality does not tremendously benefit from the competitive allocation mechanism and that the quality of the component knowledge management and learning is better when direct-award mechanisms are used. This raises questions about the lacking possibilities of actors in the field to learn about past mistakes and incorporate the finings into the future interventions, which is one of the fundamental issues of aid effectiveness.

Moreover, a new methodology has been developed for evaluating portrait stylisation algorithms, which makes use of the different benchmark levels as well as annotations provided by user studies regarding the characteristics of the faces.

Handling doctor-patient relationships collaboratively and providing patients access to their health information are crucial steps in empowering patients. In mental healthcare, the implicit consensus amongst practitioners has been that sharing medical records with patients may have an unpredictable, harmful impact on clinical practice. In order to involve patients more actively in mental healthcare processes, Tele-Board MED (TBM) allows for digital collaborative documentation in therapist-patient sessions. The TBM software system offers a whiteboard-inspired graphical user interface that allows therapist and patient to jointly take notes during the treatment session. Furthermore, it provides features to automatically reuse the digital treatment session notes for the creation of treatment session summaries and clinical case reports. This thesis presents the development of the TBM system and evaluates its effects on 1) the fulfillment of the therapist's duties of clinical case documentation, 2) patient engagement in care processes, and 3) the therapist-patient relationship. Following the design research methodology, TBM was developed and tested in multiple evaluation studies in the domains of cognitive behavioral psychotherapy and addiction care. The results show that therapists are likely to use TBM with patients if they have a technology-friendly attitude and when its use suits the treatment context. Support in carrying out documentation duties as well as fulfilling legal requirements contributes to therapist acceptance. Furthermore, therapists value TBM as a tool to provide a discussion framework and quick access to worksheets during treatment sessions. Therapists express skepticism, however, regarding technology use in patient sessions and towards complete record transparency in general. Patients expect TBM to improve the communication with their therapist and to offer a better recall of discussed topics when taking a copy of their notes home after the session. Patients are doubtful regarding a possible distraction of the therapist and usage in situations when relationship-building is crucial. When applied in a clinical environment, collaborative note-taking with TBM encourages patient engagement and a team feeling between therapist and patient. Furthermore, it increases the patient's acceptance of their diagnosis, which in turn is an important predictor for therapy success. In summary, TBM has a high potential to deliver more than documentation support and record transparency for patients, but also to contribute to a collaborative doctor-patient relationship.

Wenngleich die schriftliche Textproduktion unbestritten fester Bestandteil des Deutschunterrichts ist, wird vielfach beklagt, dass die vorhandenen Schreibkompetenzen unzureichend sind. Blickt man auf die fachdidaktische Forschung so zeigt sich, dass Schreibkompetenz ein schwer zu definierendes Ph{\"a}nomen bleibt und innerhalb der schreibdidaktischen Forschung strittig ist, wie Schreibkompetenz - insbesondere nach Erwerb der grundlegenden Schreibfertigkeiten - am Besten entwickelt werden kann. Zudem gilt f{\"u}r das Fach Deutsch, insbesondere den Aufgabenbereich „Texte verfassen", das eine empirische Fundierung der Fachdidaktik bisher kaum realisiert wurde. Vor diesem Hintergrund wurde in der vorgelegten Arbeit ein Programm zu F{\"o}rderung der schriftlichen Erz{\"a}hlf{\"a}higkeit von F{\"u}nftkl{\"a}sslern entwickelt und anschließend in der regul{\"a}ren Unterrichtspraxis eingesetzt und begleitend evaluiert. Methodisch orientiert sich die Arbeit dabei im Hinblick auf die Konzeption, Umsetzung und Evaluation des F{\"o}rderprogramms an den von Einsiedler postulierten „Standards der (didaktischen) Entwicklungsforschung". Bei der im ersten Schritt erfolgten Konzeption des F{\"o}rderprogramms ging es darum eine spezifische, didaktische Konzeption, die Kombination sprachstruktur- und (lern)prozessbezogenener Elemente, sprachwissenschaftlich basiert und p{\"a}dagogisch-didaktisch begr{\"u}ndet zu entwickeln. Bei der hierzu notwendigen Integration verschiedener theoretischer Zug{\"a}nge unterschiedlicher Fachdisziplinen galt es vorhandene Ans{\"a}tze im Hinblick auf interne Anschlussm{\"o}glichkeiten auszuloten und auf diesem Wege einen sich gegenseitig erg{\"a}nzenden, umfassenden Bezugsrahmen zu schaffen. Dabei gelang - unter Einbeziehung von Modellen und Befunden aus der Schreibentwicklungsforschung - die innerhalb der Schreibforschung vielfach geforderte, jedoch bisher fehlende Integration von strukturellen Ans{\"a}tzen aus der linguistischen Schreibforschung mit den innerhalb der Kognitionspsychologie favorisierten prozessuellen Ans{\"a}tzen. Auf dieser Grundlage wurde ein aufgabenbasiertes Programm mit insgesamt acht verschiedenen F{\"o}rdermodulen entwickelt, aufgabenbasiert deshalb, weil dies nicht nur einen lehrergesteuerten aber sch{\"u}lerzentrierten Unterricht erm{\"o}glicht, sondern auch einen adaptiven Unterricht, somit den spezifischen Anforderungen des Unterrichts in heterogenen Lerngruppen gerecht wird, was angesichts der zunehmenden (sprachlich-kulturellen) Heterogenit{\"a}t in regul{\"a}ren Schulklassen sinnvoll scheint. In einem zweiten Schritt wurde innerhalb einer Pilotstudie die Umsetzbarkeit des F{\"o}rderprogramms im schulischen Kontext erprobt. Unter Kontrolle seiner praktischen Umsetzbarkeit (Machbarkeitshypothese) wurde im Anschluss daran die Wirksamkeit des F{\"o}rderprogramms im Hinblick auf eine Steigerung in den produktbezogenen Schreibmaßen (Wortschatzvarianz, Satzkomplexit{\"a}t, lexikalische Dichte, Koh{\"a}sionsgrade, Textl{\"a}nge) und die Stabilit{\"a}t der F{\"o}rdereffekte untersucht. Dies geschah mittels eines quasiexperimentellen Untersuchungsplans, genauer eines Zweigruppen-Pretest-Posttest-Follow-up-Plans mit Kontrollvariablen. Grundlage hierf{\"u}r war eine m{\"o}glichst heterogene Stichprobe von knapp 200 Sch{\"u}ler/innen.

To fight cyclical and long-term unemployment countries spend significant shares of their budget on Active Labor Market Policies (ALMP). To improve the allocation and design of ALMP it is essential for policy makers to have reliable evidence on the effectiveness of such programs available. Although the number of studies has been increased during the last decades, policy makers still lack evidence on innovative programs and for specific subgroups of the labor market. Using Germany as a case study, the dissertation aims at contributing in this way by providing new evidence on start-up subsidies, marginal employment and programs for youth unemployed. The idea behind start-up subsidies is to encourage unemployed individuals to exit unemployment by starting their own business. Those programs have compared to traditional programs of ALMP the advantage that not only the participant escapes unemployment but also might generate additional jobs for other individuals. Considering two distinct start-up subsidy programs, the dissertation adds three substantial aspects to the literature: First, the programs are effective in improving the employment and income situation of participants compared to non-participants in the long-run. Second, the analysis on effect heterogeneity reveals that the programs are particularly effective for disadvantaged groups in the labor market like low educated or low qualified individuals, and in regions with unfavorable economic conditions. Third, the analysis considers the effectiveness of start-up programs for women. Due to higher preferences for flexible working hours and limited part-time jobs, unemployed women often face more difficulties to integrate in dependent employment. It can be shown that start-up subsidy programs are very promising as unemployed women become self-employed which gives them more flexibility to reconcile work and family. Overall, the results suggest that the promotion of self-employment among the unemployed is a sensible strategy to fight unemployment by abolishing labor market barriers for disadvantaged groups and sustainably integrating those into the labor market. The next chapter of the dissertation considers the impact of marginal employment on labor market outcomes of the unemployed. Unemployed individuals in Germany are allowed to earn additional income during unemployment without suffering a reduction in their unemployment benefits. Those additional earnings are usually earned by taking up so-called marginal employment that is employment below a certain income level subject to reduced payroll taxes (also known as "mini-job"). The dissertation provides an empirical evaluation of the impact of marginal employment on unemployment duration and subsequent job quality. The results suggest that being marginal employed during unemployment has no significant effect on unemployment duration but extends employment duration. Moreover, it can be shown that taking up marginal employment is particularly effective for long-term unemployed, leading to higher job-finding probabilities and stronger job stability. It seems that mini-jobs can be an effective instrument to help long-term unemployed individuals to find (stable) jobs which is particularly interesting given the persistently high shares of long-term unemployed in European countries. Finally, the dissertation provides an empirical evaluation of the effectiveness of ALMP programs to improve labor market prospects of unemployed youth. Youth are generally considered a population at risk as they have lower search skills and little work experience compared to adults. This results in above-average turnover rates between jobs and unemployment for youth which is particularly sensitive to economic fluctuations. Therefore, countries spend significant resources on ALMP programs to fight youth unemployment. However, so far only little is known about the effectiveness of ALMP for unemployed youth and with respect to Germany no comprehensive quantitative analysis exists at all. Considering seven different ALMP programs, the results show an overall positive picture with respect to post-treatment employment probabilities for all measures under scrutiny except for job creation schemes. With respect to effect heterogeneity, it can be shown that almost all programs particularly improve the labor market prospects of youths with high levels of pretreatment schooling. Furthermore, youths who are assigned to the most successful employment measures have much better characteristics in terms of their pre-treatment employment chances compared to non-participants. Therefore, the program assignment process seems to favor individuals for whom the measures are most beneficial, indicating a lack of ALMP alternatives that could benefit low-educated youths.}, language = {en} } @misc{Knigge2020, author = {Knigge, Michel}, title = {Use of evidence to promote inclusive education development commentary on Mel Ainscow.

Method: We examined the relation between creative and intuitive decision making in two studies-one involving coaches and one involving soccer players-using video footage of real soccer matches. Additionally, we analyzed whether this relation is culture generic or culture specific by conducting matched cross-cultural studies in a European and a South American country. Results: In Study 1, results indicate a conceptual overlap of creativity and intuition for Brazilian and German soccer coaches. Furthermore, coaches did not differ in their evaluation of creative and intuitive actions of players of both cultures. In Study 2, we found that for both subsamples the total number of generated options was positively correlated with the quality of the first and the final option and that the quality of players' first (intuitive) option was higher than that of options generated later. Moreover, results indicate a positive correlation between a player's creativity score and the quality of the first generated option for the whole sample. Conclusion: Overall, our findings provide meaningful information regarding athletes' and coaches' option-generation processes in decision making in complex team sports.}, language = {en} } @book{HermannsBoehmeMeyeringetal.2023, author = {Hermanns, Jolanda and B{\"o}hme, Katrin and Meyering, Meike and Fuchs, Isabelle and Wagner, Simon and Krauskopf, Karsten and Knigge, Michel and Rother, Stefanie and Tosch, Frank and Wendland, Mirko and Wulff, Peter and Mientus, Lukas and Nowak, Anna and Borowski, Andreas and Baer, Ella and Bosch, Jannis and Wilbert, J{\"u}rgen and Br{\"a}sel, Tim and Fenn, Monika and Kortenkamp, Ulrich and Kuzle, Ana and Reitz-Koncebovski, Karen and Burg, Paula and Lampart, Fabian and Leubner, Martin and Freitag-Hild, Britta and Bitmann, Anna and Reinhardt, Susanne and Roos, Jana and Hußner, Isabell and B{\"o}rner, Dustin and Lazarides, Rebecca and Glowinski, Ingrid and Autenrieth, Marijke and Radke, Thea and Ehlert, Antje and Menke, Anne and Haupenthal, Anna and Schramm, Satyam Antonio and Kruse, Julia and K{\"o}rner, Dorothea and Fischer, Jakob Thomas and Kayser, Daniela Niesta}, title = {PSI-Potsdam}, series = {Potsdamer Beitr{\"a}ge f{\"u}r Lehrkr{\"a}ftebildung und Bildungsforschung}, journal = {Potsdamer Beitr{\"a}ge f{\"u}r Lehrkr{\"a}ftebildung und Bildungsforschung}, number = {3}, editor = {Hermanns, Jolanda}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-568-2}, issn = {2626-3556}, doi = {10.25932/publishup-60187}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-601875}, publisher = {Universit{\"a}t Potsdam}, pages = {393}, year = {2023}, abstract = {An der Universit{\"a}t Potsdam wird seit 2015 im Rahmen der „Qualit{\"a}tsoffensive Lehrerbildung" das Projekt „Professionalisierung - Schulpraktische Studien - Inklusion" (PSI-Potsdam) durchgef{\"u}hrt und am Zentrum f{\"u}r Lehrerbildung und Bildungsforschung (ZeLB) koordiniert.

In this paper, we first study the state-of-the-art for evaluating the performances of self-healing systems by means of a systematic literature review. We provide a classification of different input types for such systems and analyse the limitations of each input type. A main finding is that the employed inputs are often not sophisticated regarding the considered characteristics for failure occurrences. To further study the impact of the identified limitations, we present experiments demonstrating that wrong assumptions regarding the characteristics of the failure occurrences can result in large performance prediction errors, disadvantageous design-time decisions concerning the selection of alternative self-healing approaches, and disadvantageous deployment-time decisions concerning parameter tuning.

The majority of European countries spends significant resources each year on active labor market programs (ALMP) with the aim of improving the integration prospects of struggling youths. Among the most common programs used are training courses, job search assistance and monitoring, subsidized employment, and public work programs. For policy makers, it is of upmost importance to know which of these programs work and which are able to achieve the intended goals - may it be the integration into the first labor market or further education. Based on a detailed assessment of the particularities of the youth labor market situation, we discuss the pros and cons of different ALMP types. We then provide a comprehensive survey of the recent evidence on the effectiveness of these ALMP for youth in Europe, highlighting factors that seem to promote or impede their effectiveness in practice. Overall, the findings with respect to employment outcomes are only partly promising. While job search assistance (with and without monitoring) results in overwhelmingly positive effects, we find more mixed effects for training and wage subsidies, whereas the effects for public work programs are clearly negative.

Seit 2011 f{\"u}hrt in den Regionen des Landes Brandenburg der Landesmusikrat Brandenburg e.V. in Kooperation mit mehreren Institutionen die zweij{\"a}hrige Fortbildung f{\"u}r fachnah sowie ausgebildete Musiklehrkr{\"a}fte im Kompetenzfeld Singen und Lieddidaktik durch. Der zugrunde liegende Evaluationsansatz stellt die Interessen der kooperierenden Partner, welche praktische Konsequenzen aus den Ergebnissen der Evaluation zu ziehen beabsichtigen, in den Mittelpunkt der Forschungsarbeit. Es handelt sich somit um eine Auftragsforschung. Der Evaluation kommen die Funktionen zu, die inhaltliche Qualit{\"a}t der Lehrkr{\"a}ftefortbildung zu sichern und zu optimieren, den Erkenntnisgewinn zur Gestaltung eines fachdidaktischen Coachings zu erweitern, die Forschungsergebnisse zur Legitimation und Partizipation sichtbar zu machen sowie analytische Entscheidungshilfe zur Weiterf{\"u}hrung Belcantare Brandenburgs nach 2022 bereitzustellen. Die von den Akteuren an die Autorin herangetragenen Forschungsanliegen wurden zu vier Fragestellungen zusammengefasst: 1. Wie zufrieden sind die Teilnehmenden mit der Veranstaltungsreihe? 2. Welche fachlichen, didaktischen und pers{\"o}nlichen Entwicklungen stellen sich w{\"a}hrend des Fortbildungszeitraumes aus der Wahrnehmungsperspektive der teilnehmenden Lehrkr{\"a}fte ein? 3. Wie beurteilen die Coaching-Beteiligten die Chancen und Grenzen des musikdidaktischen Coachings als Fortbildungsform? 4. Welche Schlussfolgerungen lassen sich hinsichtlich professioneller Lehrkr{\"a}ftefortbildung aus der Gegen{\"u}berstellung der empirischen Erkenntnisse mit denen der Theorie ziehen? Diese Forschungsfragen wurden in zwei Forschungsphasen beantwortet: 1. Der empirische Datenkorpus wurde zwischen 2011-2015 gebildet. In dieser Zeit hatten zur projektbegleitenden Qualit{\"a}tssicherung und -weiterf{\"u}hrung der Pilot- und Folgestaffel Belcantare Brandenburgs die Forschungsfragen 1, 2 und 3 besondere Relevanz. Die Evaluationsstudie ist explorativ angelegt: Die Variablen zu den Forschungsfragen 1 und 2 sind durch Dokumentenanalysen sowie Interview-auswertungen mit der Projektleitung und teilnehmenden Lehrkr{\"a}ften sukzessive herausgearbeitet. Ebenso entsprechen die halb-geschlossenen Frageb{\"o}gen als zentrale Erhebungsinstrumente der Forschungsfragen 1 und 2 dem explorativen Charakter und stellen auf diesem Weg sicher, dass den Teilnehmer*innen (N=40) die M{\"o}glichkeit zum Einbringen eigener Perspektiven einger{\"a}umt wurde. Mit der Gesamtnote „sehr gut" (1,39) seitens der befragten Lehrkr{\"a}fte gilt die Gestaltung der Veranstaltungsreihe als ein Best-Practice-Beispiel: F{\"u}r die Lehrkr{\"a}fte sind das handlungsorientierte Erarbeiten von sch{\"u}lerpassenden und thematisch geeigneten, unmittelbar einsetzbaren oder wiederholt ge{\"u}bten Unterrichtsinhalten, Lerngegenst{\"a}nden und dazu passenden Materialien f{\"u}r den Unterricht die wesentlichen Kriterien zur Nutzung einer solchen Professionalisierungsmaßnahme. Die Lehrkr{\"a}fteentwicklungen beider beforschter Staffeln zeigen, dass die fachnahen Kr{\"a}fte bei sich gr{\"o}ßere Entwicklungszuw{\"a}chse nach Beendigung des Projektes wahrnehmen als die Fachkr{\"a}fte. Gleichzeitig liegt die selbsteingesch{\"a}tzte Fachkompetenz der fachnahen Kr{\"a}fte zu Fortbildungsende unter denen der Fachkr{\"a}fte. Der Forschungsfrage 3 liegt ein ausschließlich qualitatives Design (N=16) zugrunde. Im Ergebnis konnten die Offene Form fachdidaktischen Coachings definiert werden, deren Parameter beschrieben und wesentliche Eigenschaften von Coach-Constellationen f{\"u}r ein binnendifferenziertes Coaching in der Lehrkr{\"a}ftefortbildung benannt werden. 2. Im Mai 2019 bildete sich aufgrund des sich versch{\"a}rfenden Fachkr{\"a}ftemangels in Brandenburg das Bestreben der Kooperationspartner heraus, die Lehrkr{\"a}ftefortbildung nach 2022 als qualit{\"a}tssichernde Maßnahme fortf{\"u}hren zu wollen. Diese Situation f{\"u}hrte 2019 zur Aufnahme der Forschungsfrage 4, die eine umfassende und aktualisierte Analyse der theoretischen und bildungspolitischen Hintergr{\"u}nde der Intervention implizierte, mit dem Ziel, den Erkenntnisstand der Evaluation f{\"u}r eine erneute Empfehlung zu vertiefen.
