Background: Clinicians are currently challenged to support older adults to maintain a certain level of Functional Independence (FI). FI is defined as "functioning physically safely and independent from another person, within one's own context". A Core Outcome Set was developed to measure FI. The purpose of this study was to assess discriminative validity of the Core Outcome Set FI (COSFI) in a population of Dutch older adults (≥ 65 years) with different levels of FI. Secondary objective was to assess to what extent the underlying domains 'coping', 'empowerment' and 'health literacy' contribute to the COSFI in addition to the domain 'physical capacity'. Methods: A population of 200 community-dwelling older adults and older adults living in residential care facilities were evaluated by the COSFI. The COSFI contains measurements on the four domains of FI: physical capacity, coping, empowerment and health literacy. In line with the COSMIN Study Design checklist for Patient-reported outcome measurement instruments, predefined hypotheses regarding prediction accuracy and differences between three subgroups of FI were tested. Testing included ordinal logistic regression analysis, with main outcome prediction accuracy of the COSFI on a proxy indicator for FI. Results: Overall, the prediction accuracy of the COSFI was 68%. For older adults living at home and depending on help in (i)ADL, prediction accuracy was 58%. 60% of the preset hypotheses were confirmed. Only physical capacity measured with Short Physical Performance Battery was significantly associated with group membership. Adding health literacy with coping or empowerment to a model with physical capacity improved the model significantly (p < 0.01). Conclusions: The current composition of the COSFI, did not yet meet the COSMIN criteria for discriminative validity. However, with some adjustments, the COSFI potentially becomes a valuable instrument for clinical practice. Context-related factors, like the presence of a spouse, also may be a determining factor in this population. It is recommended to include context-related factors in further research on determining FI in subgroups of older people.
Thirty to sixty per cent of older patients experience functional decline after hospitalisation, associated with an increase in dependence, readmission, nursing home placement and mortality. First step in prevention is the identification of patients at risk. The objective of this study is to develop and validate a prediction model to assess the risk of functional decline in older hospitalised patients.
The research proposal aims to improve the design and verification process for coastal protection works. With global sea levels rising, the Netherlands, in particular, faces the challenge of protecting its coastline from potential flooding. Four strategies for coastal protection are recognized: protection-closed (dikes, dams, dunes), protection-open (storm surge barriers), advancing the coastline (beach suppletion, reclamation), and accommodation through "living with water" concepts. The construction process of coastal protection works involves collaboration between the client and contractors. Different roles, such as project management, project control, stakeholder management, technical management, and contract management, work together to ensure the project's success. The design and verification process is crucial in coastal protection projects. The contract may include functional requirements or detailed design specifications. Design drawings with tolerances are created before construction begins. During construction and final verification, the design is measured using survey data. The accuracy of the measurement techniques used can impact the construction process and may lead to contractual issues if not properly planned. The problem addressed in the research proposal is the lack of a comprehensive and consistent process for defining and verifying design specifications in coastal protection projects. Existing documents focus on specific aspects of the process but do not provide a holistic approach. The research aims to improve the definition and verification of design specifications through a systematic review of contractual parameters and survey methods. It seeks to reduce potential claims, improve safety, enhance the competitiveness of maritime construction companies, and decrease time spent on contractual discussions. The research will have several outcomes, including a body of knowledge describing existing and best practices, a set of best practices and recommendations for verifying specific design parameters, and supporting documents such as algorithms for verification.
Public safety is under enormous pressure. Demonstrations regularly result in riots and VIPs are often threatened even at their homes ! Criminal graffiti-gangs are threatening security professionals and costing the Dutch railways (NS), causing a loss of 10 M€ yearly. The safety incidents often escalate quickly, therefore, they require a very quick and correct scaling up of the security professionals. To do so, it is necessary for the security professionals to get very quick and accurate overview of the evolving situation using Mobile Drone intervention unit for quick response (Mobi Dick). The successfully completed project The Beast (9/11) has delivered a universal docking station with an automatic security drone. The drone takes off from a permanently installed docking station. Nest Fly emerged as a startup from this RAAK project, and it has already developed the prototype further to a first product. Based on extensive interaction with security professionals, it has been concluded that a permanently installed docking station is not suitable for all emergency cases. Therefore, a mobile, car-roof top mounted, docking station with a ready-for-take-off drone is required for the more severe and quickly escalating incidents. These situations require a drone taking off from the car-roof top mounted docking station while the vehicles continue to drive towards the incident. In this RAAK KIEM, a feasibility study will be executed by developing a car-roof top docking station. The concept will functionally be designed within the project (task 1). The two required subsystems car roof docking station (task 2) and dynamic take-off & landing (task 3) will technically be developed and integrated (task 4). The outcome of the experiments in this task will show the feasibly of the idea. Task 5 will ensure the results are disseminated in new cooperation’s, publications, and educational products.
In leaving the more traditional territories of the concert performance for broader societal contexts, professional musicians increasingly devise music in closer collaboration with their audience rather than present it on a stage. Although the interest for such forms of devising co-creative musicking within the (elderly) health care sector is growing, the work can be considered relatively new. In terms of research, multiple studies have sought to understand the impact of such work on musicians and participants, however little is known about what underpins the musicians’ actions in these settings. With this study, I sought to address this gap by investigating professional musicians’ emerging practices when devising co-creative musicking with elderly people. Three broad concepts were used as a theoretical background to the study: Theory of Practice, co-creative musicking, and Praxialism. Firstly, I used Theory of Practice to help understand the nature of emerging practices in a wider context of change in the field of music and habitus of musicians and participants. Theory of Practice enabled me to consider a practice as “a routinized type of behaviour which consists of several elements, interconnected to one another: forms of bodily activities, forms of mental activities, ‘things’ and their use, a background knowledge in the form of understanding, know-how, states of emotion, and motivational knowledge” (Reckwitz, 2002, p. 249). Secondly, I drew the knowledge from co-creative musicking, which is a concept I gathered from two existing concepts: co-creation and musicking. Musicking (Small, 1998), which considers music as something we do (including any mode of engagement with music), provided a holistic and inclusive way of looking at participation in music-making. The co-creation paradigm encompasses a view on enterprise that consists of bringing together parties to jointly create an outcome that is meaningful to all (Prahalad & Ramaswamy, 2004; Ramaswamy & Ozcan, 2014). The concept served as a lens to specify the jointness of the musicking and challenge issues of power in the engagement of participants in the creative-productive process. Thirdly, Praxialism considers musicking as an activity that encompasses “musical doers, musical doing, something done and contexts in which the former take place” (Elliott, 1995). Praxialism sets out a vision on music that goes beyond the musical work and includes the meanings and values of those involved (Silverman, Davis & Elliott, 2014). The concept allowed me to examine the work and emerging relationships as a result of devising co-creative musicking from an ethical perspective. Given the subject’s relative newness and rather unexplored status, I examined existing work empirically through an ethnographic approach (Hammersley & Atkinson, 2007). Four cases were selected where data was gathered through episodic interviewing (Flick, 2009) and participant observation. Elements of a constructivist Grounded Theory (Charmaz, 2014) were used for performing an abductive analysis. The analysis included initial coding, focused coding, the use of sensitizing concepts (Blumer 1969 in Hammersley, 2013) and memoing. I wrote a thick description (Geertz, 1973) for each case portraying the work from my personal experience. The descriptions are included in the dissertation as one separate chapter and foreshadow the exposition of the analysis in a next chapter. In-depth study of the creative-productive processes of the cases showed the involvement of multiple co-creative elements, such as a dialogical interaction between musicians and audience. However, participants’ contributions were often adopted implicitly, through the musicians interpreting behaviour and situations. This created a particular power dynamic and challenges as to what extent the negotiation can be considered co-creative. The implicitness of ‘making use’ of another person’s behaviour with the other not (always) being aware of this also triggered an ethical perspective, especially because some of the cases involved participants that were vulnerable. The imbalance in power made me examine the relationship that emerges between musicians and participants. As a result of a closer contact in the co-creative negotiation, I witnessed a contact of a highly personal, sometimes intimate, nature. I recognized elements of two types of connections. One type could be called ‘humanistic’, as a friendship in which there is reciprocal care and interest for the other. The other could be seen as ‘functional’, which means that the relationship is used as a resource for providing input for the creative musicking process. From this angle, I have compared the relationship with that of a relationship of an artist with a muse. After having examined the co-creative and relational sides of the interaction in the four cases, I tuned in to the musicians’ contribution to these processes and relationships. I discovered that their devising in practice consisted of a continuous double balancing act on two axes: one axis considers the other and oneself as its two ends. Another axis concerns the preparedness and unpredictability at its ends. Situated at the intersection of the two axes are the musicians’ intentionality, which is fed by their intentions, values and ethics. The implicitness of the co-creation, the two-sided relationship, the potential vulnerability of participants, and the musicians’ freedom in navigating and negotiation, together, make the devising of co-creative musicking with elderly people an activity that involves ethical challenges that are centred around a tension between prioritizing doing good for the other, associated with a eudaimonic intention, and prioritizing values of the musical art form, resembling a musicianist intention. The results therefore call for a musicianship that involves acting reflectively from an ethical perspective. Doctoral study by Karolien Dons
