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’.

Horizontal collaborative purchasing (HCP) has often been cited as a way for hospitals to address the challenges of the rising healthcare costs. However, hospitals do not seem to utilize horizontal collaborative purchasing on any large scale, and recent initiatives have had mixed results. Focusing on Dutch hospitals, in this paper we present major impediments for collaborative purchasing, resulting in a first component of our proposed electronic horizontal collaborative purchasing model for hospitals; as a second component it contains a collaborative purchasing typology. A first validation round with hospital purchasing professionals, described separately in Kusters and Versendaal (2011), confirmed four applicable purchasing types and fourteen salient collaborative purchasing impediments. The model is operationalized by including possible information technology (IT) solutions that address the specific fourteen impediments. This model is validated through methodological triangulation of four different validation techniques. We conclude that IT has the potential to support, or overcome, the impediments of HCP. The validation also reveals the need to distinguish between more processrelated, as opposed to social-related, obstacles; the immediate potential for IT solutions is greater for the process-related impediments. Ultimately, we conclude that the collaborative epurchasing model (e-HCP) and implementation roadmap can be used by healthcare consortia, branche organizations, partnering healthcare institutes and multi-site healthcare institutes as a means to help identifying strategies to initiate, manage and evaluate collaborative purchasing practices

In: Frank Gadinger, Martina Kopf, Ayşem Mert, and Christopher Smith (eds.). Political Storytelling: From Fact to Fiction (Global Dialogues 12) This essay presents a summary of important perspectives concerning the distinction between what counts as truth or fiction. As a source of inspiration, it starts with two examples found in literature – the first a classical Spanish novel and the second a collection of stories written by the leader of a social movement in Mexico. These two examples of the conflictive relations between truth and fiction, authenticity and imagination serve as a source of inspiration for the rest of this article, which shows that this issue has been a subject of intense debate in philosophy and in the philosophy of science and still presents a challenge in the 21st century. The essay states that absolute, objective truth is a myth. It describes that what counts as ‘truth’ in a particular era, is, among other things, the result of power relations. It suggests productive ways to deal with this problem in modern society, through deliberative, emancipatory processes of reflexivity (Weick 1999), participatory research and dialogue, facilitating innovation and generation of new solutions.

This study explores if multiple alterations of the classrooms' indoor environmental conditions, which lead to environmental conditions meeting quality class A of Dutch guidelines, result in a positive effect on students' perceptions and performance. A field study, with a between-group experimental design, was conducted during the academic course in 2020–2021. First, the reverberation time (RT) was lowered in the intervention condition to 0.4 s (control condition 0.6 s). Next, the horizontal illuminance (HI) level was raised in the intervention condition to 750 lx (control condition 500 lx). Finally, the indoor air quality (IAQ) in both conditions was improved by increasing the ventilation rate, resulting in a reduction of carbon dioxide concentrations, as a proxy for IAQ, from ~1100 to <800 ppm. During seven campaigns, students' perceptions of indoor environmental quality, health, emotional status, cognitive performance, and quality of learning were measured at the end of each lecture using questionnaires. Furthermore, students' objective cognitive responses were measured with psychometric tests of neurobehavioural functions. Students' short-term academic performance was evaluated with a content-related test. From 201 students, 527 responses were collected. The results showed that the reduction of the RT positively influenced students' perceived cognitive performance. A reduced RT in combination with raised HI improved students' perceptions of the lighting environment, internal responses, and quality of learning. However, this experimental condition negatively influenced students' ability to solve problems, while students' content-related test scores were not influenced. This shows that although quality class A conditions for RT and HI improved students' perceptions, it did not influence their short-term academic performance. Furthermore, the benefits of reduced RT in combination with raised HI were not observed in improved IAQ conditions. Whether the sequential order of the experimental conditions is relevant in inducing these effects and/or whether improving two parameters is already beneficial, is unknown.

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.

Many students persistently misinterpret histograms. This calls for closer inspection of students’ strategies when interpreting histograms and case-value plots (which look similar but are diferent). Using students’ gaze data, we ask: How and how well do upper secondary pre-university school students estimate and compare arithmetic means of histograms and case-value plots? We designed four item types: two requiring mean estimation and two requiring means comparison. Analysis of gaze data of 50 students (15–19 years old) solving these items was triangulated with data from cued recall. We found five strategies. Two hypothesized most common strategies for estimating means were confirmed: a strategy associated with horizontal gazes and a strategy associated with vertical gazes. A third, new, count-and-compute strategy was found. Two more strategies emerged for comparing means that take specific features of the distribution into account. In about half of the histogram tasks, students used correct strategies. Surprisingly, when comparing two case-value plots, some students used distribution features that are only relevant for histograms, such as symmetry. As several incorrect strategies related to how and where the data and the distribution of these data are depicted in histograms, future interventions should aim at supporting students in understanding these concepts in histograms. A methodological advantage of eye-tracking data collection is that it reveals more details about students’ problem-solving processes than thinking-aloud protocols. We speculate that spatial gaze data can be re-used to substantiate ideas about the sensorimotor origin of learning mathematics.

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 chapter, the focus is on arithmetic which for the Netherlands as a trading nation is a crucial part of the mathematics curriculum.The chapter goes back to the roots of arithmetic education in the sixteenth century and compares it with the current approach to teaching arithmetic. In the sixteenth century, in the Netherlands, the traditional arithmetic method using coins on a counting board was replaced by written arithmetic with Hindu–Arabic numbers. Many manuscripts and books written in the vernacular teach this new method to future merchants, money changers, bankers, bookkeepers, etcetera. These students wanted to learn recipes to solve the arithmetical problems of their future profession. The books offer standard algorithms and many practical exercises. Much attention was paid to memorising rules and recipes, tables of multiplication and other number relations. It seems likely that the sixteenth century craftsmen became skilful reckoners within their profession and that was sufficient. They did not need mathematical insight to solve new problems. Five centuries later we want to teach our students mathematical skills to survive in a computerised and globalised society. They also need knowledge about number relations and arithmetical rules, but they have to learn to apply this knowledge flexibly and meaningfully to solve new problems, to mathematise situations, and to evaluate, interpret and check output of computers and calculators. The twenty-first century needs problem solvers, but to acquire the skills of a good problem solver a firm knowledge base—comparable with that of the sixteenth century reckoner—is still necessary.
