Mise en oeuvre de l’atelier d’écriture des projets de recherche en République démocratique du Congo
(2020)
Tout en offrant un cadre d’apprentissage et d’émancipation scientifique, l’atelier d’écriture des projets oppose différents défis, d’ordre organisationnel et didactique, dont les approches influent sur son déploiement et sur l’atteinte des objectifs assignés. Comment s’y prendre pour contourner ces défis et accomplir avec succès l’implémentation de la formation proposée ? Quelle en est l’incidence sur la qualité des acquisitions des participants au terme de la formation ? Le présent article répond à ces questions, partant des observations faites lors des formations organisées à Kinshasa (République démocratique du Congo) dans le cadre du programme National Multiplication Training (NMT). Il en ressort que le succès d’un atelier réside dans la pertinence des approches mises en oeuvre. Le recours à l’approche participative a favorisé les échanges constructifs entre participants, formateurs et experts, et a permis à tous les participants de finaliser des projets cohérents, pour postuler aux financements nationaux et internationaux.
Whilst providing a framework for learning and scientific emancipation, a proposal writing training is confronted with various organisational and didactic challenges, which influence the achievement of the set training objectives. Based on observations made during the workshops for proposal writing organised in Kinshasa, Democratic Republic of Congo, as part of the NMT Programme, the article raises two main questions: (a) How could these challenges be overcome and successfully addressed in the training? (b) What is the level of learning outcomes of the participants at the end of the training? The article shows that the success of the training lays in the relevance of the employed training approaches. The use of a participatory approach encouraged constructive exchanges between participants, trainers, and experts, and enabled all participants to finalise coherent projects to apply for national and international funding.
Les établissements d’enseignement supérieur en Guinée sont confrontés à de nombreux défis, notamment les responsabilités en matière de rapports, la mondialisation et la massification. Les évaluations institutionnelles des établissements d’enseignement supérieur (EES) et de recherche en 2013 n’ont pas permis d’initier la mise en oeuvre des processus de changement au sein des établissements. Récemment, diverses initiatives ont été lancées pour changer cette situation dans le but de sensibiliser et de renforcer la prise de conscience et les capacités des structures d’assurance qualité dans les EES guinéennes. Jusqu’à présent, l’accent a été mis sur l’amélioration de la qualité dans l’enseignement supérieur, en particulier sur l’évaluation de l’enseignement, l’élaboration des programmes d’études, ainsi que sur la mise en place de structures d’assurance qualité. Cet article donne un aperçu de l’état des lieux et fait le point sur les activités qui ont été lancées pour mettre en place des mécanismes d’assurance qualité dans les établissements d’enseignement supérieur et de recherche, et présente les perspectives de développement de l›approche qualité en Guinée. Le projet «Multiplication de l’assurance qualité 2017 – 2018» sert d’exemple pour décrire les approches et les activités de mise en place de structures stables d’assurance qualité, et pour renforcer et sensibiliser à une «culture de la qualité».
The paper investigates the question of sustainability of capacity building initiatives by reporting about the multiplication training in the frame of DIES NMT Programme on quality assurance in Uganda and how it could make use of the social capital within the existing quality assurance network to sustain and address challenges during its implementation. The purpose of the article is to explore the nature of networking (social and institutional) which was established by the Ugandan Universities Quality Assurance Forum (UUQAF) and share the strategies used in this training experience for future sustainable capacity building training initiatives in emerging economies. The paper employed a qualitative research method to describe and analyse the training framework based on primary and secondary documents.
Higher education institutions in Guinea face many challenges, including reporting responsibilities, globalisation, and massification. Institutional evaluations of higher education and research institutions in 2013 could not initiate the implementation of change processes within the institutions. Recently, however, various initiatives have been started to change this situation with the purpose to sensitise and raise awareness and capabilities for quality assurance structures in Guinean HEIs. So far, the emphasis has been put on quality enhancement in higher education, especially on teaching evaluation, curriculum development, as well as on establishing quality assurance structures. This article gives an overview of the state of play and takes stock of the activities that have been initiated to set up quality assurance mechanisms in higher education and research institutions, and presents perspectives for further development of the quality approach in Guinea. The project ‘Quality Assurance Multiplication 2017-2018’ serves as an example to describe approaches and activities in setting up stable quality assurance structures, and to strengthen and raise awareness for a ‘quality culture’.
Alles auf (Studien-)Anfang? Faktoren für den Studienerfolg in der Eingangsphase und zur Studienmitte
(2020)
Die hohen Abbruchquoten, insbesondere in der Studieneingangsphase, haben die Hochschulen in Deutschland veranlasst, eine Vielzahl von Maßnahmen zu ergreifen, über deren Wirkungen bisher allerdings wenig bekannt ist. Im vorliegenden Beitrag werden Befunde eines Forschungsprojekts speziell zur Studieneingangsphase sowie ergänzend zur Studienmitte vorgestellt, dessen Ziel es war, Bedingungen eines erfolgreichen Studieneinstiegs zu identifizieren und Empfehlungen für eine Optimierung des Studieneingangs abzuleiten. Das Forschungsdesign umfasste neben qualitativen Studien vor allem eine quantitative Längsschnittbefragung an fünf Universitäten (Potsdam, Mainz, Magdeburg, Kiel und Greifswald). Im Ergebnis der Analysen konnte die forschungsleitende Hypothese, dass Maßnahmen zum Studieneingang vor allem dann zur Erhöhung des Studienerfolgs einen Beitrag leisten, wenn sie zur akademischen und sozialen Integration in die Hochschule beitragen, bestätigt werden. Bedeutsam für den Studienerfolg sind demnach insbesondere solche Faktoren wie die Identifikation mit dem Studienfach, die Selbstwirksamkeit, die berufliche bzw. erfolgsorientierte Lernmotivation und die akademische Integration. Daneben konnte ein positiver Einfluss des sozialen Klimas sowie des Forschungs- und Praxisbezugs auf die Studienzufriedenheit nachgewiesen werden. Weiterführende Analysen zur Studienmitte verdeutlichen zudem, dass für die beiden Studienphasen (Eingang und Studienmitte) gleiche Faktoren bei zum Teil unterschiedlicher Gewichtung eine Rolle spielen. So ist die soziale Integration ein wesentlicher Prädiktor in beiden Phasen – in der Eingangsphase eher in die Studierendenschaft und im weiteren Studienverlauf (Studienmitte) eher in die akademische Gemeinschaft (in Form von Lehrenden). Insofern muss die Eingangsfrage wie folgt beantwortet werden: Ja, alles auf Anfang, aber dann mit den Bemühungen, soziale und akademische Integration aller Studierenden voll und ganz zu gewährleisten. Zudem machen die Befunde auf die bisher offenbar unterschätzte Rolle von Verwertungsmotiven aufmerksam.

As competition over peer status becomes intense during adolescence, some adolescents develop insecure feelings regarding their social standing among their peers (i.e., social status insecurity). These adolescents sometimes use aggression to defend or promote their status. The aim of this study was to examine the relationships among social status insecurity, callous-unemotional (CU) traits, and popularity-motivated aggression and prosocial behaviors among adolescents, while controlling for gender. Another purpose was to examine the potential moderating role of CU traits in these relationships. Participants were 1,047 (49.2% girls; Mage = 12.44 years; age range from 11 to 14 years) in the 7th or 8th grades from a large Midwestern city. They completed questionnaires on social status insecurity, CU traits, and popularity-motivated relational aggression, physical aggression, cyberaggression, and prosocial behaviors. A structural regression model was conducted, with gender as a covariate. The model had adequate fit. Social status insecurity was associated positively with callousness, unemotional, and popularity-motivated aggression and related negatively to popularity-motivated prosocial behaviors. High social status insecurity was related to greater popularity-motivated aggression when adolescents had high callousness traits. The findings have implications for understanding the individual characteristics associated with social status insecurity.
Carbon nitride and poly(ionic liquid)s (PILs) have been successfully applied in various fields of materials science owing to their outstanding properties. This thesis aims at the successful application of these polymers as innovative materials in the interfaces of hybrid organic–inorganic perovskite solar cells. A critical problem in harnessing the full thermodynamic potential of halide perovskites in solar cells is the design and modification of interfaces to reduce carrier recombination. Therefore, the interface must be properly studied and improved. This work investigated the effect of applying carbon nitride and PILs on a perovskite surface on the device performance. The facile synthetic method for modifying carbon nitride with vinyl thiazole and barbituric acid (CMB-vTA) yields 2.3 nm layers when solution processing is performed using isopropanol. The nanosheets were applied as a metal-free electron transport layer in inverted perovskite solar cells. The application of carbon nitride layers (CMB-vTA) resulted in negligible current-voltage hysteresis with a high open circuit voltage (Voc) of 1.1 V and a short-circuit current (Jsc) of 20.28 mA cm-2, which afforded efficiencies of up to 17%. Thus, the successful implementation of a carbon nitride-based structure enabled good charge extraction with minimized interface recombination between the perovskite and PCBM. Similarly, PILs represent a new strategy of interfacial modification using an ionic polymer in an n-i-p perovskite architecture.. The application of PILs as an interfacial modifier resulted in solar cell devices with an extraordinarily high efficiency of 21.8% and a Voc of 1.17 V. The implementation reduced non-radiative recombination at the perovskite surface through defect passivation. Finally, our work proposes a novel method to efficiently suppress non-radiative charge recombination using the unexplored properties of carbon nitride and PILs in the solar cell field. Additionally, the method for interfacial modification has general applicability because of the simplicity of the post-treatment approach, and therefore has potential applicability in other solar cells. Thus, this work opens the door to a new class of materials to be implemented.
This study sought to analyze the relationship between in-season training workload with changes in aerobic power (VO2max), maximum and resting heart rate (HRmax and HRrest), linear sprint medium (LSM), and short test (LSS), in soccer players younger than 16 years (under-16 soccer players). We additionally aimed to explain changes in fitness levels during the in-season through regression models, considering accumulated load, baseline levels, and peak height velocity (PHV) as predictors. Twenty-three male sub-elite soccer players aged 15.5 ± 0.2 years (PHV: 13.6 ± 0.4 years; body height: 172.7 ± 4.2 cm; body mass: 61.3 ± 5.6 kg; body fat: 13.7% ± 3.9%; VO2max: 48.4 ± 2.6 mL⋅kg–1⋅min–1), were tested three times across the season (i.e., early-season (EaS), mid-season (MiS), and end-season (EnS) for VO2max, HRmax, LSM, and LSS. Aerobic and speed variables gradually improved over the season and had a strong association with PHV. Moreover, the HRmax demonstrated improvements from EaS to EnS; however, this was more evident in the intermediate period (from EaS to MiS) and had a strong association with VO2max. Regression analysis showed significant predictions for VO2max [F(2, 20) = 8.18, p ≤ 0.001] with an R2 of 0.45. In conclusion, the meaningful variation of youth players’ fitness levels can be observed across the season, and such changes can be partially explained by the load imposed.
The present paper looks into the grammaticalization of the definite article in the history of German. Starting with the well-known emergence of the definite article from a demonstrative pronoun over the course of Old High German (750–1050), I will consider the rise of so-called weak definites in Early New High German (1350–1650) as a new piece of evidence for the grammaticalization process. Here, the subclass of possessive weak definites is of particular interest for the grammaticalization of the definite article in German, because of a word order change affecting the position of possessor phrases. As soon as the possessor systematically follows the head noun (except for proper names), we observe three alternatives for the prenominal determiner slot: it may remain empty, or it may be filled either by the indefinite or the definite article in Early New High German. In Present-Day German, the definite article is used in the unmarked case, thus pointing to a second stage in the grammaticalization process of the definite article in German, which has so far not been acknowledged in the literature.
