In Nordic countries, as well as in the Netherlands, schools have high school autonomy. In schools there are both horizontal and vertical working relations and all teachers and school principals within a school are expected to take responsibility for collaborative-innovation practices (CIP). In this paper, we describe a study investigating how both horizontal and vertical working relations relate to CIP. We used longitudinal questionnaire (2036 teachers, 157 schools) and interview data (53 teachers, 20 schools). These data were gathered in Dutch schools participating in the large-scale ‘LeerKRACHT’ program. The results show that teachers perceive horizontal and vertical factors to enhance CIP. Furthermore, especially school principals and coach-teachers seem to be able to strengthen horizontal and vertical factors which leads to more CIP. We discuss implications for research and schools in the Netherlands and beyond. Schools operate in demanding and rapidly changing environments. As a result, teachers and school principals are expected to continuously improve their school practices to maintain the quality of the education they provide. In literature on school development, change, and reform, there is an increasing emphasis on investigating how various educational interventions turn out. Some of these studies highlighted that interventions are sometimes an isolated activity of one teacher or a small group of teachers According to Vangrieken et al. in education, a strong-rooted culture of individualism, autonomy, and independence appears to be dominant. A ‘culture of collaboration’, however, has many advantages. This is also shown in research traditions of whole-school improvement. It can result in more ‘school democracy’ and more appropriate ideas and solutions for the challenges faced by schools. A growing number of schools have begun to initiate types of teacher collaboration, such as ‘professional learning communities’ and ‘data teams’. Such collaborations of teachers in schools can be called horizontal working relations. Researchers from Nordic countries for instance studied the horizontal forms of accountability and responsibility in schools. Consequently, international scholars have called for more ‘networked’ and ‘collaborative’ approaches. In the organizational literature, the notion of collaborative innovation is used for such approaches, which is characterized by both horizontal and vertical working relations. This notion fits within the broader field of school development research that approaches development as a collaborative process as well. Here both teachers’ working relations (horizontal) and working relations between teachers and school principals are studied (vertical). Studying both fits with the culture of The Netherlands and Nordic countries, which are found to be in the same cultural clusters, appreciating team-oriented and participative leadership, including horizontal and vertical working relations. However, in daily school practice it seems that breaking with the individualistic culture and changing to more collaborative-innovation practices is hard. We have an unique opportunity to study the relationship between horizontal and vertical working relations and the degree of collaborative-innovation practices (CIP). Since, in the Netherlands there is a large-scale program called LeerKRACHT that aims to stimulate CIP in schools (LeerKRACHT means “Learning force” and also “Teacher” in Dutch). The program expects from both teachers and school principals to collaborate and share resources, knowledge, and ideas and it thus asks for at least one manner of working together. The program is used by over a thousand schools in the Netherlands, and the data used in the current paper are gathered as part of a larger research project in which this program was evaluated. We study the degree of CIP in primary, secondary, and vocational schools with a mixed method approach both at the start and when working on collaborative-innovation practices in a structured way with the program ‘leerKRACHT’.

University teacher teams can work toward educational change through the process of team learning behavior, which involves sharing and discussing practices to create new knowledge. However, teachers do not routinely engage in learning behavior when working in such teams and it is unclear how leadership support can overcome this problem. Therefore, this study examines when team leadership behavior supports teacher teams in engaging in learning behavior. We studied 52 university teacher teams (281 respondents) involved in educational change, resulting in two key findings. First, analyses of multiple leadership types showed that team learning behavior was best supported by a shared transformational leadership style that challenges the status quo and stimulates team members’ intellect. Mutual transformational encouragement supported team learning more than the vertical leadership source or empowering and initiating structure styles of leadership. Second, moderator analyses revealed that task complexity influenced the relationship between vertical empowering team leadership behavior and team learning behavior. Specifically, this finding suggests that formal team leaders who empower teamwork only affected team learning behavior when their teams perceived that their task was not complex. These findings indicate how team learning behavior can be supported in university teacher teams responsible for working toward educational change. Moreover, these findings are unique because they originate from relating multiple team leadership types to team learning behavior, examining the influence of task complexity, and studying this in an educational setting. https://www.scienceguide.nl/2021/06/leren-van-docentteams-vraagt-om-gezamenlijk-leiderschap/

Semi-closed greenhouses have been developed in which window ventilation is minimized due to active cooling, enabling enhanced CO2 concentrations at high irradiance. Cooled and dehumidified air is blown into the greenhouse from below or above the canopy. Cooling below the canopy may induce vertical temperature gradients along the length of the plants. Our first aim was to analyze the effect of the positioning of the inlet of cooled and dehumidified air on the magnitudes of vertical temperature and VPD gradients in the semi-closed greenhouses. The second aim was to investigate the effects of vertical temperature gradients on assimilate production, partitioning, and fruit growth. Tomato crops were grown year-round in four semiclosed greenhouses with cooled and dehumidified air blown into the greenhouses from below or above the crop. Cooling below the canopy induced vertical temperature and VPD gradients. The temperature at the top of the canopy was over 5°C higher than at the bottom, when outside solar radiation was high (solar radiation >250 J cm-2 h-1). Total dry matter production was not affected by the location of the cooling (4.64 and 4.80 kg m-2 with cooling from above and from below, respectively). Percentage dry matter partitioning to the fruits was 74% in both treatments. Average over the whole growing season the fresh fruit weight of the harvested fruits was not affected by the location of cooling (118 vs 112 g fruit-1). However, during summer period the average fresh fruit weight of the harvested fruits in the greenhouse with cooling from below was higher than in the greenhouse with cooling from above (124 vs 115 g fruit-1).

Brand portfolio strategies are an essential prerequisite for securing long-term success for multi-brand companies. Only by focusing on the entire portfolio can it be ensured that all brands “act in concert” to achieve superordinate objectives. Thereby, an increasing vertical competition caused by private labels calls for a new approach, by which brand manufacturers integrate private labels into their portfolio management. This paper presents a planning model that is embedded in the company’s strategic management and demonstrates how brand-related objectives/strategies can be linked with superordinated objectives/strategies. By including vertical marketing goals into portfolio strategy, brand manufacturers may gain from extending the planning scope to private label brands.

In this paper we introduce a novel highly interactive process to generate natural language narratives on the basis of our ongoing work on semiotic relations. To the two basic components of interactive systems, namely, a software tool and a user interface, we add a third component - AI agents, understood as an upgraded rendition of software agents. Our semiotic relations approach considers four ways of composing new narratives from existing narratives. Along what semioticians call the horizontal syntagmatic axis, one can form the new narrative by combining two or more previous narratives. Along the vertical paradigmatic axis, the new narrative may emerge as a similar version, which imitates the previous one, possibly in a different context. Along the depth meronymic axis, the hierarchic narrative levels, such as plot, event, and scene, are explored, allowing either expansion or summarization. Lastly, the antithetic consideration, rather than adding a dimension, aims at some form of reversal, through the adoption of opposite values. A fully operational prototype is described. Its name, ChatGeppetto, conflates the skilled Geppetto, who fashioned Pinocchio, an early case of artisanship-produced human level intelligence, with ChatGPT, which operates as the main AI agent component. To run the experiments, we concentrated on book narratives.

Over 40% of nursing home residents in the Netherlands are estimated to have visual impairments. In this study, light conditions in Dutch nursing homes were assessed in terms of horizontal and vertical illuminances and colour temperature. Results showed that in the seven nursing homes vertical illuminances in common rooms fell significantly below the 750 lx reference value in at least 65% of the measurements. Horizontal illuminance measurements in common rooms showed a similar pattern. At least 55% of the measurements were below the 750 lx threshold. The number of measurements at the window zone was significantly higher than the threshold level of 750 lx. Illuminances in the corridors fell significantly below the 200 lx threshold in at least three quarters of the measurements in six of the seven nursing homes. The colour temperature of light fell significantly below the reference value for daylight of 5000 K with median scores of 3400 to 4500 K. A significant difference in colour temperature was found between recently constructed nursing homes and some older homes. Lighting conditions of the examined nursing homes were poor. With these data, nursing home staff have the means to improve the lighting conditions, for instance, by encouraging residents to be seated next to a window when performing a task or during meals.

Educational innovations often tend to fail, mainly because teachers and school principals do not feel involved or are not allowed to have a say. Angela de Jong's dissertation shows the importance of school principals and teachers leading 'collaborative innovation' together. Collaborative innovation requires a collaborative, distributed approach involving both horizontal and vertical working relationships in a school. Her research shows that teams with more distributed leadership have a more collaborative 'spirit' to improve education. Team members move beyond formal (leadership) roles, and work more collectively on school-wide educational improvement from intrinsic motivation. De Jong further shows that school principals seek a balance in steering and providing space. She distinguished three leadership patterns: Team Player, Key Player, Facilitator. Team players in particular are important for more collaborative innovation in a school. They balance between providing professional space to teachers (who look beyond their own classroom) and steering for strategy, frameworks, boundaries, and vision. This research took place in schools working with the program of Foundation leerKRACHT, a program implemented by more than a thousand schools (primary, secondary, and vocational education). The study recommends, towards school principals and teachers, and also towards trainers, policymakers, and school board members, to reflect more explicitly on their roles in collaborative innovation and talk about those roles.

from the article: ABSTRACT Independence of design, information and complexity are the basic concepts of Axiomatic Design. These basic concepts have proven to be generic; axiomatic design was successfully applied in many markets and on a broad range of products and services. Information, or entropy, plays a central role in Axiomatic Design. In this paper an attempt is made to organise the different kinds of information, understand them, and evaluate the consequences of the ways they can be applied. A number of six kinds of information are reduced to two most determining kinds of information for the design. Unorganised information is about choosing the right and independent design relations. Axiomatic information is about further optimisation of these design relations. This paper leads to the confirmation that axiom 1 & 2 are in fact corollaries of the complexity axiom that is constituted of the two kinds of information. Though this revises the foundation of Axiomatic Design, the operation and practical application are not much affected for a number of reasons. One of them is that a higher axiom does not alter the basic ideas behind Axiomatic Design; it remains axiomatic.
