Continuously changing conditions of sociotechnical systems are the basis of structural changes in communities. Relationships between transition contexts and regime transformation processes and their driving factors in sociotechnical regimes are poorly understood. Moreover, not all changes in multilevel governance regimes are geared towards sustainability, as demonstrated by the case of the water management regime in Sanandaj county in the west of Iran between 1962 and 2018. The current study shows how the management regime of water resources in the case study has changed over time and identifies the institutional arrangements through a retrospective analysis. The analysis is based on three stages of data collection which included a discussion group, a Delphi survey, and a focus group survey among various types of stakeholders. The “Hybrid Transitions” framework is introduced in order to denote processes of regime change that take place in a range of different transition contexts. The findings do not identify a single transition pathway but show that a number of parallel transition pathways have occurred in the context of groundwater and surface water management and their respective institutional arrangements. The study provides a better understanding of the complexity of transition pathways that were devised at the management regime level.

How can European library staff working in digital humanities connect with peers in the library sector, determine where to find relevant information about digital scholarship, provide their collections as data and to be an equal partner in digital humanities research? The LIBER Digital Humanities Working Group was created as a participatory knowledge network in 2017 to address these questions. Through a series of workshops, knowledge sharing activities, and a Europe-wide survey and resulting report, the Working Group engaged with the international LIBER DH community. Useful reflections are provided on organising an open, voluntary DH community and planning for inclusive activities that benefit digital scholarship in European research libraries.

This research aims to reveal the perceptions of the preservice teachers on the play which are among the essential needs of the preschool children. In this descriptive study, a case study which is one of the qualitative research designs was used. 79 preservice teachers attending the third grade in the Classroom Teaching Department of state university in Nigde province in Turkey. Convenience sampling method was used in the selection of the study group. A semi-structured interview form was prepared in order to reveal the perceptions of preservice teachers about the play. Content analysis technique was used for data analysis. At the end of the research, it was determined that the preschool teacher candidates expressed the essential needs of preschool children as nutrition, education and love respectively. The play was ranked as the number four among these needs.

The flipped classroom, as an active learning model, has given remarkable results in several areas in the university teaching; however, its execution is still able to improve. This research shows the implementation and improvement of the flipped classroom model in the course of Pavements. It evaluates their influence on the students’ final grades and their learning experience. Three groups of students participated in this study, who enrolled in the course of Pavements in the Civil Engineering. Group A took the course with the traditional model, while Group B took it with a flipped classroom, and Group C experienced it with a reinforced flipped model. Groups did the course the subject in 2017, 2018 and 2019, respectively. Results show that even though with the flipped classroom models, the finals grades did not increase compared to the scores of the traditional model; however, it improved their learning experience. The students were more satisfied with the method; they even asked for fewer modifications than they did in the traditional model. This research shows that adding little academic things to the course, it would greatly influence their students' opinion.

Globally, there is agreement that school–community partnerships are one of the mechanisms to address challenges that schools cannot address alone. However, evidence suggests that where school–community partnerships have been initiated, their functionality and continuity is not always easy to achieve, and research locally and internationally has not sufficiently addressed this concern. To bridge this gap, guided by Epstein’s theory of overlapping spheres of influence, this paper examined what makes school–community partnerships functional and sustainable. The research used a qualitative case study and employed discursive oriented interviews (both individual and focus group), a researcher’s reflective journal, and document reviews to generate the data. Participants were principals, teachers, and academics from two universities. It was found that for partnerships to be functional and sustainable there is a need to ensure that there is collaborative planning and decision-making, effective two-way communication, eagerness to address power issues, and the creation of a culture that promotes participative leadership. From these findings, the paper concludes that principal’s leadership is only critical at the beginning stage of partnerships, and teacher leadership is central in the functionality and continuity of partnerships. In relation to the theoretical framework, it is further concluded that power is an important element to consider, which either brings partners together or pushes them apart.
