The aim of this explorative study was to determine the key inertial measurement unit-based wheelchair mobility performance components during a wheelchair tennis match. A total of 64 wheelchair tennis matches were played by 15 wheelchair tennis players (6 women, 5 men, 4 juniors). All individual tennis wheelchairs were instrumented with inertial measurement units, two on the axes of the wheels and one on the frame. A total of 48 potentially relevant wheelchair tennis outcome variables were initially extracted from the sensor signals, based on previous wheelchair sports research and the input of wheelchair tennis experts (coaches, embedded scientists). A principal component analysis was used to reduce this set of variables to the most relevant outcomes for wheelchair tennis mobility. Results showed that wheelchair mobility performance in wheelchair tennis can be described by six components: rotations to racket side in (1) curves and (2) turns; (3) linear accelerations; (4) rotations to non-racket side in (4) turns and (5) curves; and finally, (6) linear velocities. One or two outcome variables per component were selected to allow an easier interpretation of results. These key outcome variables can be used to adequately describe the wheelchair mobility performance aspect of wheelchair tennis during a wheelchair tennis match and can be monitored during training.

From the article: With increasing investments in business rules management (BRM), organizations are searching for ways to value and benchmark their processes to elicitate, design, accept, deploy and execute business rules. To realize valuation and benchmarking of previously mentioned processes, organizations must be aware that performance measurement is essential, and of equal importance, which performance indicators to apply to the performance measurement processes. However, scientific research on BRM, in general, is limited and research that focuses on BRM in combination with performance indicators is nascent. The purpose of this paper is to define performance indicators for previously mentioned BRM processes. We conducted a three round focus group and three round Delphi Study which led to the identification of 14 performance indicators. Presented results provide a grounded basis from which further, empirical, research on performance indicators for BRM can be explored.

AIM To examine which instruments used to assess participation of children with acquired brain injury (ABI) or cerebral palsy (CP) align with attendance and/or involvement constructs of participation; and to systematically review measurement properties of these instruments in children with ABI or CP, to guide instrument selection. METHOD Five databases were searched. Instruments that quantified ‘attendance’ and/or ‘involvement’ aspects of participation according to the family of participation-related constructs were selected. Data on measurement properties were extracted and methodological quality of the studies assessed. RESULTS Thirty-seven instruments were used to assess participation in children with ABI or CP. Of those, 12 measured attendance and/or involvement. The reliability, validity, and responsiveness of eight of these instruments were examined in 14 studies with children with ABI or CP. Sufficient measurement properties were reported for most of the measures, but no instrument had been assessed on all relevant properties. Moreover, most psychometric studies have marked methodological limitations. INTERPRETATION Instruments to assess participation of children with ABI or CP should be selected carefully, as many available measures do not align with attendance and/or involvement. Evidence for measurement properties is limited, mainly caused by low methodological study quality. Future studies should follow recommended methodological guidelines.

More than 25!years after Moore’s first introduction of the public value concept in 995, the concept is now widely used, but its operationalization is still considered difficult. This paper presents the empirical results of a study analyzing the application of the public value concept in Higher Education Institutions, thereby focusing on how to account for public value. The paper shows how Dutch universities of applied sciences operationalize the concept ‘public value’, and how they report on the outcome achievements. The official strategy plans and annual reports for FY2016 through FY2018 of the ten largest institutions were used. While we find that all the institutions selected aim to deliver public value, they still use performance indicators that have a more narrow orientation, and are primarily focused on processes, outputs, and service delivery quality. However, we also observe that they use narratives to show the public value they created. In this way this paper contributes to the literature on public value accounting.

Athlete impairment level is an important factor in wheelchair mobility performance (WMP) in sports. Classification systems, aimed to compensate impairment level effects on performance, vary between sports. Improved understanding of resemblances and differences in WMP between sports could aid in optimizing the classification methodology. Furthermore, increased performance insight could be applied in training and wheelchair optimization. The wearable sensor-based wheelchair mobility performance monitor (WMPM) was used to measure WMP of wheelchair basketball, rugby and tennis athletes of (inter-)national level during match-play. As hypothesized, wheelchair basketball athletes show the highest average WMP levels and wheelchair rugby the lowest, whereas wheelchair tennis athletes range in between for most outcomes. Based on WMP profiles, wheelchair basketball requires the highest performance intensity, whereas in wheelchair tennis, maneuverability is the key performance factor. In wheelchair rugby, WMP levels show the highest variation comparable to the high variation in athletes’ impairment levels. These insights could be used to direct classification and training guidelines, with more emphasis on intensity for wheelchair basketball, focus on maneuverability for wheelchair tennis and impairment-level based training programs for wheelchair rugby. Wearable technology use seems a prerequisite for further development of wheelchair sports, on the sports level (classification) and on individual level (training and wheelchair configuration).

Het belang van innovatie voor economische groei en het scheppen van werkgelegenheid in het MKB wordt erkend door zowel academici als politici. Er worden daarom programma’s ontwikkeld om innovatie te stimuleren. Met deze maatregelen ontstaat de vraag te bepalen of deze initiatieven succesvol zijn en zo ja, in welke mate. In de literatuur hebben we geen indicator gevonden die ons in staat stelt de mate van innovativiteit van MKB bedrijven te bepalen voor een dergelijke interventie en daarna. De hoofdvraag van ons onderzoek was dan ook: hoe kunnen we het effect van een interventie voor het bevorderen van de innovatiekracht van MKB-bedrijven meten? Kijkend naar de definities van innovatie zoals die zijn verzameld door King & Anderson (2002) hebben we vastgesteld dat een bedrijf innovatief genoemd mag worden als het met opzeten succesvol nieuwe ideeën implementeert. Succesvol wil in dit verband zeggen: het draagt bij aan de winst en dus aan de continuïteit van het desbetreffende MKB-bedrijf. Door de verschillende (bewuste) innovaties te identificeren samen met de ondernemer en te berekenen wat de winstgevendheid is geweest van de innovaties, kunnen we de ’innovatiewinst’ van de ondernemer berekenen. Dit bedrag delen door de omzet creëert een indicator waarmee de innovativiteit van de organisatie door de tijd gemeten kan worden. Wij stellen daarom de volgende definitie van innovatiekracht voor: KIKR = [ [Winst Innovatie1+Winst Innovatie2+ ... +Winst Innovatie5] / Omzet] x 100. De ratio kan alleen met voldoende betrouwbaarheid bepaald worden door een gestructureerd interview met de directeur/ eigenaar van de het bedrijf door een gekwalificeerde gesprekspartner. De auteurs realiseren zich dat dit gesprek op zichzelf misschien een interventie is, omdat de ervaring leert dat het innovatiebewustzijn van de ondernemer er door toeneemt. Om te bepalen of dit daadwerkelijk zo is, en om te testen of de KIKR inderdaad als bruikbare maat voor innovatiekracht kan worden gebruikt is vervolgonderzoek noodzakelijk. Desalniettemin zijn de auteurs van mening dat met de KIKR de innovatiekracht van bedrijven door de tijd heen gemeten kan worden en daarmee een bruikbaar instrument is om het effect te bepalen van interventies die innovatiekracht moeten vergroten. The importance of innovation as an engine for economic growth and the creation of employment opportunities is acknowledged by both academia and politicians. This makes the need for good innovation measures crucial. In the third edition of the Oslo Manual (2005), a need for proper indicators to capture the changes in the nature and landscape of innovation is voiced. According to the manual, a considerable body of models and analytical frameworks for innovation were developed in the 1980s and 1990s. Over time, the scope of what is considered as innovation has been widened and expanded to include marketing and organizational innovation. In this paper, we focus on innovative performance as a measure of success. This is part of ongoing research in the Netherlands in The Hague region. This research is framed within an approach based on action research. We have worked with 45 SMEs in four sectors. This has formed the basis for the conceptual development of innovative performance as a new metric for the measurement of a successful innovation. In this paper, we review our findings thus far and explore the validity of innovative performance as an appropriate indicator for measuring innovation within SMEs.

Quantifying measures of physical loading has been an essential part of performance monitoring within elite able-bodied sport, facilitated through advancing innovative technology. In wheelchair court sports (WCS) the inter-individual variability of physical impairments in the athletes increases the necessity for accurate load and performance measurements, while at the same time standard load monitoring methods (e.g. heart-rate) often fail in this group and dedicated WCS performance measurement methods are scarce. The objective of this review was to provide practitioners and researchers with an overview and recommendations to underpin the selection of suitable technologies for a variety of load and performance monitoring purposes specific to WCS. This review explored the different technologies that have been used for load and performance monitoring in WCS. During structured field testing, magnetic switch based devices, optical encoders and laser systems have all been used to monitor linear aspects of performance. However, movement in WCS is multidirectional, hence accelerations, decelerations and rotational performance and their impact on physiological responses and determination of skill level, is also of interest. Subsequently both for structured field testing as well as match-play and training, inertial measurement units mounted on wheels and frame have emerged as an accurate and practical option for quantifying linear and non-linear movements. In conclusion, each method has its place in load and performance measurement, yet inertial sensors seem most versatile and accurate. However, to add context to load and performance metrics, position-based acquisition devices such as automated image-based processing or local positioning systems are required.

Big data analytics received much attention in the last decade and is viewed as one of the next most important strategic resources for organizations. Yet, the role of employees' data literacy seems to be neglected in current literature. The aim of this study is twofold: (1) it develops data literacy as an organization competency by identifying its dimensions and measurement, and (2) it examines the relationship between data literacy and governmental performance (internal and external). Using data from a survey of 120 Dutch governmental agencies, the proposed model was tested using PLS-SEM. The results empirically support the suggested theoretical framework and corresponding measurement instrument. The results partially support the relationship of data literacy with performance as a significant effect of data literacy on internal performance. However, counter-intuitively, this significant effect is not found in relation to external performance.

Various tools for safety performance measurement have been introduced in order to fulfil the need for safety monitoring in organisations, which is tightly related to their overall performance and achievement of their business goals. Such tools include accident rates, benchmarking, safety culture and climate assessments, cost-effectiveness studies, etc. The current work reviews the most representative methods for safety performance evaluation that have been suggested and applied by a variety of organisations, safety authorities and agencies. This paper discusses several viewpoints of the applicability, feasibility and appropriateness of such tools, based on the viewpoints of managers and safety experts involved in a relevant research that was conducted in a large aviation organisation. The extensive literature cited, the discussion topics, along with the conclusions and recommendations derived, might be considered by any organisation that seeks a realistic safety performance assessment and establishment of effective measurement tools.

USE conference paper.Ever since the mid-1970s a multitude of studies linking corporate sustainability performance (CSP) measures and financial performance measures have been conducted. Until today a plethora of corporate sustainability performance measures heve been developed. A universally accepted CSP definition of construct does not (yet) exist. Since we don't exactley know what CSP entails, CSP measures should (at least) be considered conceptually flawed for that matter. These measures may measure CSP, but it cannot e excluded that other (overarching) phenomena are measured. There are leads suggesting that CSP measures are reflections or representations of corporate culture, suggesting that corporate culture drives FP. If so, managers should not focus on increasing CSP to boost FP, but create a high culture for sustainability If corporate culture drives financial performance, the investment community can also benefit through improving its decision making processes by including CSP measures that reflect corporate culture.
