In this chapter we discuss the implications of our research in the wider context of current models of brain function, endeavoring to understand the consequences of score-dependence and improvisation in terms of the ‘predicting brain’, the dual-stream model of perception and action, the procedural-declarative model of learning and memory, ideomotor learning and sensorimotor mapping, and the implicit acquisition of hierarchical music syntax.

The realization of one’s musical ideas at the keyboard is dependent on the ability to transform sound into movement, a process called audiomotor transformation. Using fMRI, we investigated cerebral activations while classically‐trained improvising and non‐improvising musicians imagined playing along with recordings of familiar and unfamiliar music excerpts. We hypothesized that audiomotor transformation would be associated with the recruitment of dedicated cerebral networks, facilitating aurally‐cued performance. Results indicate that while all classically‐trained musicians engage a left‐hemisphere network involved in motor skill and action recognition, only improvising musicians additionally recruit a right dorsal frontoparietal network dedicated to spatially‐driven motor control. Mobilization of this network, which plays a crucial role in the real‐time transformation of imagined or perceived music into goal‐directed action, may be held responsible not only for the stronger activation of auditory cortex we observed in improvising musicians in response to the aural perception of music, but also for the superior ability to play ‘by ear’ which they demonstrated in a follow‐up study. The results of this study suggest that the practice of improvisation promotes the implicit acquisition of hierarchical music syntax which is then recruited in top‐down manner via the dorsal stream during music performance.

Neighborhood image processing operations on Field Programmable Gate Array (FPGA) are considered as memory intensive operations. A large memory bandwidth is required to transfer the required pixel data from external memory to the processing unit. On-chip image buffers are employed to reduce this data transfer rate. Conventional image buffers, implemented either by using FPGA logic resources or embedded memories are resource inefficient. They exhaust the limited FPGA resources quickly. Consequently, hardware implementation of neighborhood operations becomes expensive, and integrating them in resource constrained devices becomes unfeasible. This paper presents a resource efficient FPGA based on-chip buffer architecture. The proposed architecture utilizes full capacity of a single Xilinx BlockRAM (BRAM36 primitive) for storing multiple rows of input image. To get multiple pixels/clock in a user defined scan order, an efficient duty-cycle based memory accessing technique is coupled with a customized addressing circuitry. This accessing technique exploits switching capabilities of BRAM to read 4 pixels in a single clock cycle without degrading system frequency. The addressing circuitry provides multiple pixels/clock in any user defined scan order to implement a wide range of neighborhood operations. With the saving of 83% BRAM resources, the buffer architecture operates at 278 MHz on Xilinx Artix-7 FPGA with an efficiency of 1.3 clock/pixel. It is thus capable to fulfill real time image processing requirements for HD image resolution (1080 × 1920) @103 fcps.

This paper presents an approach to organizational research that aims to produce research results that are both relevant and rigorous. The research approach combines the designing of a management tool with the testing of the tool using an action research methodology. The lack of relevance in organizational research is a much debated issue in literature. A design approach has been proposed to help bridge the gap between research and practice. However, in organizational research, there is little empirical evidence how design-based research works in practice and it is unclear how this type of research is best structured. The purpose of the paper is to illustrate what a comprehensive methodology for design-based research can look like and how an action research methodology can be used to test the design in practice.

With the rise of the knowledge-based economy, Higher Education Institutions not only have to produce (under)graduates that are skilled in their profession but who also are competent as knowledge workers. This study focused on the enabling competences of the knowledge worker. Our aim was to develop a framework of enabling competences of knowledge work and to devise instruments to help undergraduate students create awareness of their own areas of competence in relation to knowledge work. We developed a Personal Priority Questionnaire (PPQ) that can be used in a one hour facilitated group discussion, and a Personal Mastery Questionnaire (PMQ) that can be used for individual awareness raising. We did a preliminary test of the PPQ within the competence-based educational program of a university of professional education in The Netherlands and found that facilitated group discussion seems to be an effective method of raising awareness in relation to the competences of the knowledge worker

Purpose: Small and medium-sized entities (SMEs) operating in the alternative financing sector are typically heterogenous in nature making them differ greatly from traditional banks. Where traditional banks must comply with strict banking regulations, developing uniform regulations for the alternative financing sector remains a challenge. This paper examines the current challenges and solutions from a sociological and institutional perspective in developing standards for SMEs operating in the alternative financing sector in the Netherlands. Adopting minimum quality standards should lead to increased transparency and public trust in the non-banking sector.

The sources of productivity have always been the main subject of economic debate because they are the main determinants of profitability and competitiveness. In order to improve productivity we should be able to identify the sources of productivity. This article presents a method for measuring the sources of knowledge productivity in order to give direction to knowledge management initiatives. The method is based on a theoretical framework which combines two different perspectives (economic and process) on knowledge productivity. This article presents the methodological and theoretical framework, the initial design of the method and the results of the first two case studies. The relevance of this article is that it combines the concepts of knowledge management and intellectual capital measurement in the relatively new concept of knowledge productivity.

In solving systemic design challenges designers co-create with professionals from various fields. In the context of innovation in healthcare practices, this study investigates design abilities that healthcare professionals develop by participating in co-design projects. We conducted a mixed-methods research approach consisting of five retrospective interviews with healthcare researchers involved in co-design projects, and a multiple case study (three cases) on the collaboration between design researchers and healthcare professionals. The three cases all aimed at designing tools for healthcare innovation. The cases differ in the healthcare context and the professionals involved: Paediatric physical therapists in the treatment of babies (0-2 years), supervisors (e.g. in assisted living) of people with intellectual disabilities, and academic researchers in social sciences and design research developing e-health applications for elderly people with early stages of dementia. Literature states that healthcare professionals may be competent in specific abilities related to design, but they are not trained to mode-shift and to use two different ways of working for creativity. We found that the healthcare professionals involved in co-design projects developed design ability over time, and that the research setting was supportive. Based on design abilities that the five healthcare researchers explicated in the interviews as having adopted, we suggest eight mode-shift practices related to design, which we investigated in the cases. Findings of the case-study show that two mode-shift practices related to design and innovation are difficult to adopt for healthcare professionals: Generate and synthesize; and keeping track on overview and details. These two design abilities require more training and/or experience than the other six design abilities that ran smoothly in the cases, if healthcare professionals were facilitated in the process. Healthcare professionals specifically relate two of these practices to design: Collaboration and slow down – sprint. This study discusses these findings by referring to an analogy of kayaking on a wild water river: The collaboration aspect of switching between working in a group and by yourself, like a group of kayakers who collaborate in going down stream a river but peddle by themselves in their own boats; the slowdown and sprint aspect, like kayakers who oversee the river in turning waters and sprint in between, rather than go with the flow in a raft.

The digital era has brought about profound changes in how music is created, distributed, and consumed, posing a need for modernizing the Dutch collective management system of music copyright to match the rapidly changing digital music industry. This study aims to identify the key stakeholders and their perceptions of the Dutch system of collective management of music copyright. Utilizing qualitative document analysis, the study examines a range of public and non-public documents, including income statements, annual reports from Collective Management Organizations (CMOs), and contracts between publishers and creators. The research is further enriched by twenty-four semi-structured interviews with key stakeholders such as composers, lyricists, music publishers, copyright lawyers, and CMO executives. The findings of the study highlight several issues like the outdated IT systems and the lack of data standardization within the system. The research also notes a contrast in organizational effectiveness: major publishers are well-organized and unified in their negotiations with Digital Service Providers (DSPs) and CMOs, effectively advocating for their rights. However, music copyright holders, despite their legal homogeneity, are either unorganized or ineffectively aligned, displaying diverse interests and varying levels of access to information, as well as differences in norms and values prioritization. The study is grounded in the economics of collective management (ECM) and makes a significant academic contribution to this field by introducing new empirical findings to ECMs core constructs and integrating theoretical perspectives. The research offers valuable insights for policymakers, industry stakeholders, and researchers, aiming to foster a more equitable music copyright management system in the digital context.

The studies in this thesis aim to increase understanding of the effects of various characteristics of scientific news about a common chronic disease, i.e., diabetes, on the cognitive responses (e.g., emotions, attitudes, intentions) of diabetes patients. The research questions presented in this thesis are guided by the Health Belief Model, a theoretical framework developed to explain and predict healthrelated behaviours based on an individual’s beliefs and attitudes. The model asserts that perceived barriers to a recommended health behavior, advantages of the behavior, self-efficacy in executing the behavior, and disease severity and personal susceptibility to the disease are important predictors of a health behavior. Communication is one of the cues to action (i.e., stimuli) that may trigger the decision-making process relating to accepting a medical or lifestyle recommendation.
