The models presented are the pro rata model, the user-centric model (UCM), a progressive extension of the UCM and an alternative model. It focuses on a critique of the UCM as an alternative remuneration model, arguing that the UCM has the potential for economic devaluation, which can be exposed through simple logical analysis. It also provides criteria for fair remuneration in a distribution model.

A user-centric model of connectivity in street networks

Modelling street network connectivity is a fundamental research problem in transportation science. Here, we argue that the connectivity of a street network cannot be defined independently from the users of that street network. That is, different users will experience different levels of connectivity depending on their corresponding travel behaviour. In this work, we propose a model of connectivity that is defined with respect to a user’s travel behaviour within a given street network. We demonstrate that many real-world problems can be posed as instances of an optimisation problem defined with respect to this model. This includes optimising a user’s home location with respect to their connectivity and optimising the location of a facility with respect to the connectivity of its users. We prove the above optimisation problem is NP-hard and present an integer programming solution that scales to large problem instances.

Integrating explainable machine learning and user-centric model for diagnosing cardiovascular disease: A novel approach

Conventional machine learning techniques in diagnosing cardiovascular disease have a limitation owing to the lack of interpretability of models. This study utilised an explainable machine learning approach to predict the likelihood of having CVD. Four machine learning models were employed for CVD diagnosis: Decision Tree (DT), K-Nearest Neighbor (KNN), Random Forest (RF), and Extreme Gradient Boost (XGB). Shapley Additive Explanations (SHAP) were used to provide reasoning for the models' predictions. Using these models and explanations, a user interface was developed to assist in diagnosing CVD. All four classification models demonstrated good accuracy in diagnosing CVD, with the KNN model showcasing the best performance (Accuracy: 71 %). SHAP provided the reasoning behind KNN predictions, and the predictive interface was developed by embedding these explanations to provide transparency behind the model's decisions.

A Qualitative Exploration of a User-Centered Model for Smartwatch Comfort Using Grounded Theory

Smartwatch comfort is a fundamental factor that significantly influences the user experience and provides crucial guidance for the evolution of wearable technology. However, there is currently a lack of a comprehensive theoretical model to describe the dimensions of smartwatch comfort and their corresponding influencing factors. Therefore, the present study employed a bottom-up grounded theory approach to construct a user-centered model for smartwatch comfort. Through the coding of in-depth interviews with 64 smartwatch users, we discovered that smartwatch comfort encompasses both physiological dimensions (e.g., pressure and foreign body sensation) and psychological dimensions (e.g., perceived intelligence and satisfaction of needs). Furthermore, the features of smartwatches, including physical attributes (e.g., size and material) and functionalities (e.g., interoperability and automation capabilities), directly impact the comfort experience. Additionally, individual and contextual factors can explain variations in the comfort experience of smartwatches. Users with different physiological characteristics (e.g., wrist size and body sensitivity) and psychological needs (e.g., utilitarian or hedonic needs) are influenced differently by the factors of smartwatches that affect their comfort experience. The adaptability of smartwatches across different contexts (including task context, social context, and temporal context) is also a significant influencing factor on comfort. This substantive grounded theory provides crucial guidance for the selection of core variables in future quantitative research and contributes to the development of smarter, more comfortable, and user-centric smartwatches.

User-Centered Development of HEARTPrep, a Digital Health Psychosocial Intervention for Prenatally Diagnosed Congenital Heart Disease.

User-centered models for the development of digital health interventions are not consistently applied in healthcare settings. This study used a five-phase, user-centered approach to develop HEARTPrep©, a psychosocial intervention delivered via mobile app and telehealth to mothers expecting a baby with congenital heart disease (CHD) to promote maternal, family, and child well-being. Phases of intervention development were: (I) establishing partnerships; (II) creating content; (III) developing prototype and testable intervention; (IV) conducting think-aloud testing; and (V) completing beta testing. Partnerships with parents, clinicians, and design/technology experts were integral throughout the development of HEARTPrep©. Parents of children with CHD also served as participants in Phases II-V, contributing to the creation of content and providing feedback to inform the iterative refinement of HEARTPrep©. These five phases produced a refined digital health intervention with promising feasibility, usability, and acceptability results. This user-centered approach can be used to develop digital health interventions targeting various health outcomes.

Designing A User-Centred Model to Amplify Satisfaction in Utilizing Online Government Information

With the increasing reliance on digital platforms for accessing government services and information, user satisfaction becomes a crucial factor in ensuring effective service delivery and citizen engagement. Thus, this study explores into the development of a user-centred model aimed at enhancing user satisfaction in the utilization of online government information. The proposed model integrates Privacy; Safety; Service quality; Time; and Awareness with Satisfaction to create a model that aligns with citizens' needs and preferences. The data collection process targeted respondents among citizens of the United Arab Emirates (UAE) for the questionnaire survey. The respondents were selected using a convenience sampling technique, allowing for the collection of samples conveniently located around a specific area or accessible through internet services. A total of 396 participants took part in the survey and the collected data was used to develop the model using SmartPLS software. The developed model was analysed and the results reveal that the path from Privacy to Satisfaction holds significant influence, as indicated by a T statistic of 3.755 and a p-value of 0.000. Similarly, the paths from Safety and Service Quality to Satisfaction are also significant, with T statistics of 2.363 and 4.580, respectively, and corresponding p-values of 0.009 and 0.000. However, the paths from Awareness and Time to Satisfaction are found to be not significant, with T statistics of 1.162 and 0.935, and p-values of 0.123 and 0.175, respectively. By prioritizing user satisfaction, this research contributes to the advancement of digital government initiatives and citizen-centric service delivery paradigms.

Technology Transfer Model for Small-Scale Farms

Small-scale farms make an important contribution to food security, but they lack technification, especially in the global south. This article proposes a new model, namely, Model H, as a reference by which to facilitate technological transfer and appropriation in small producer sectors. Starting with the identification of interactions with the environment and the characterization of the transfer and appropriation process with respect to information and communication technologies, a five-stage framework is established to create and validate the new model. Based on key elements, functionalities, and five variables identified as a common ground for the transfer and appropriation of technologies, Model H is presented as a five-layer, user-centered model that aims to include in the transfer and appropriation of the solutions of all the individuals and entities that participate throughout the process. The model is validated through a pilot test using an intelligent irrigation technology called AgroRIEGO. In the process of technology transfer and appropriation, this pilot study helped to identify implementation obstacles and the importance of knowledge management as an effective channel for the exchange of information in a pertinent and timely manner.

Multi-user centered design: acceptance, user experience, user research and user testing

In recent years, technologies have evolved towards social, universal and collaborative uses involving multiple users. However, methods and models from user centered design are focused on single-user design and do not take into account the impact of other users on intentions and behaviors to use the technology. The objective of this article is to provide paths of reflection on how to integrate a multi-user centered approach to existing user centered design methods and models. Each phase of user-centered design has been rethought to implement this new framework. Guidelines for moving from user experience to Multi-User eXperience (MUX) are provided. In the same way, we recommend adding a multi-user variable in the technology acceptance models to become the Multi-user Acceptance Model (MAM). User research and user testing have also been rethought to a multi-user reach and a multi-user testing. All these considerations are discussed, and lead to a proposal of a future Multi-user Centered Design (MCD) approach, specifically adapted to manage multi-user digital technology development projects. Finally, it is therefore necessary and important to direct research in the fields (acceptance, user experience, user research and user testing) to assist designers with the development of new methods of product design more respectful of social, environmental and collaborative values.

The governance and management of green spaces in Addis Ababa, Ethiopia

Despite the increase in the depletion of green spaces, studies on the governance of green space management are limited in rapidly urbanizing African cities, this study examines the application of urban park management models, governance principles, and identifies barriers related to governance processes in Addis Ababa, Ethiopia. Qualitative and quantitative research methods were employed to obtain and analyze data. In general, the study has identified poor park governance practices. However, there is a tendency towards the application of governance by local communities using the User-Centered Model whereby community green spaces are managed by urban communities. The findings suggest the need to focus on a long-term design that encompasses additional recreational areas and to establish integrated green space management. Adapting the strategic park management and park-organization-user model that incorporates three governance levels is also important. This research contributes to the emerging literature on the governance of the management models used for parks, protected areas, and community green spaces. The analysis of park management models and governance principles presented may be useful for the sustainable long-term management of green spaces in urbanizing African cities.

Towards the Development of a Mobile Application in Movement Competency Training Grounded on the User-Centered Design Model: The Case of a State University in the Philippines

The corona-virus disease (COVID)-19 pandemic has caused extreme disruption in the delivery of instruction in many educational institutions all over the world. However, this circumstance may not only be a challenge but also an opportunity to foster learning through exploration of various technologies that can be developed, more specifically in a course characterized with a strong skills-based orientation such as physical education (PE). Therefore, the aim set in this study was to develop a mobile application for Movement Competency Training (MCT) grounded on the User-Centered Design Model. This descriptive mixed-method research started with a preliminary needs assessment analysis which was participated by 121 Filipino students enrolled in the MCT course and 10 PE teachers. Results revealed the skills that require a higher degree of proficiency such as non-locomotor skills, locomotor, and mobility skills. Also, the majority of the respondents are mobile phone users which justified the adoption of mobile instruction and the development of an application for MCT. Moreover, indicated in this research was the preference of the intended users in terms of design and interface that led to the development of the mobile application and had specified the requirements based on the users' needs. The initial assessment of the developed application indicated a highly acceptable level of functional suitability, usability, and portability by the student-respondents. A field testing of the application may be recommended to determine its effectiveness in mastering the skills in MCT independently.

Digitale technologie in de geestelijke gezondheidszorg: een narratieve review en visietekst op weg naar gepersonaliseerde zorg

Digital technology in mental health care: a narrative review and vision on the road to personalised care Mental health problems are prevalent and are associated with a huge societal cost. Therefore, there is an urgent need for improvements in mental health care focusing on a person-centered approach. Digital technology offers a unique opportunity to contribute to a better understanding of the specific needs of an individual person by actively engaging this person in his or her treatment process. In this paper, the authors introduce the experience sampling method (ESM) as a clinical instrument fit for this purpose. ESM is a structured diary technique, provided on an app, that allows to assess individuals in their normal daily life. The authors demonstrate that a clinical application of ESM contributes to 1. more engagement and empowerment, 2. better self-management and recovery, 3. improved goal direction in clinical assessment and management of care, and 4. more shared decision making. They also discuss the implementation of ESM in routine mental health care and introduce the European project IMMERSE, which is specifically targeted on the clinical implementation of ESM in 4 European countries. This extensive international project will contribute to the implementation of ESM in clinical practice, resulting in a personalized, proactive, user-centered model of mental health care, transforming patients from passive care users into active managers of their own care.

An Electronic Patient-Reported Outcome Mobile App for Data Collection in Type A Hemophilia: Design and Usability Study.

BackgroundThere is currently limited evidence on the level and intensity of physical activity in individuals with hemophilia A. Mobile technologies can offer a rigorous and reliable alternative to support data collection processes but they are often associated with poor user retention. The lack of longitudinal continuity in their use can be partly attributed to the insufficient consideration of stakeholder inputs in the development process of mobile apps. Several user-centered models have been proposed to guarantee that a thorough knowledge of the end user needs is considered in the development process of mobile apps.ObjectiveThe aim of this study is to design and validate an electronic patient-reported outcome mobile app that requires sustained active input by individuals during POWER, an observational study that aims at evaluating the relationship between physical activity levels and bleeding in patients with hemophilia A.MethodsWe adopted a user-centered design and engaged several stakeholders in the development and usability testing of this mobile app. During the concept generation and ideation phase, we organized a need-assessment focus group (FG) with patient representatives to elicit specific design requirements for the end users. We then conducted 2 exploratory FGs to seek additional inputs for the app’s improvement and 2 confirmatory FGs to validate the app and test its usability in the field through the mobile health app usability questionnaire.ResultsThe findings from the thematic analysis of the need-assessment FG revealed that there was a demand for sense making, for simplification of app functionalities, for maximizing integration, and for minimizing the feeling of external control. Participants involved in the later stages of the design refinement contributed to improving the design further by upgrading the app’s layout and making the experience with the app more efficient through functions such as chatbots and visual feedback on the number of hours a wearable device had been worn, to ensure that the observed data were actually registered. The end users rated the app highly during the quantitative assessment, with an average mobile health app usability questionnaire score of 5.32 (SD 0.66; range 4.44-6.23) and 6.20 (SD 0.43; range 5.72-6.88) out of 7 in the 2 iterative usability testing cycles.ConclusionsThe results of the usability test indicated a high, growing satisfaction with the electronic patient-reported outcome app. The adoption of a thorough user-centered design process using several types of FGs helped maximize the likelihood of sustained retention of the app’s users and made it fit for data collection of relevant outcomes in the observational POWER study. The continuous use of the app and the actual level of engagement will be evaluated during the ongoing trial.Trial RegistrationClinicalTrials.gov NCT04165135; https://clinicaltrials.gov/ct2/show/NCT04165135

Games in Normal and Satisfaction Form for Efficient Transmission Power Allocation Under Dual 5G Wireless Multiple Access Paradigm

In this paper, to exploit the challenges and potential offered by the simultaneous use of non-orthogonal multiple access (NOMA) and orthogonal frequency division multiple access (OFDMA) transmission options in future 5G wireless systems, we aim at the proper modeling and transformation of the uplink power allocation problem. In particular, in this setting, each user has two degrees of freedom in the decision making process, namely its overall transmission power level, and the corresponding power investment to the OFDMA and/or NOMA based transmissions. The resulting multi-variable power allocation problem is treated and solved under three different perspectives, namely: 1) Games in Normal Form and Nash Equilibrium (NE); 2) Optimization techniques targeting system social welfare through a centralized optimal solution; and 3) Games in Satisfaction Form and Efficient Satisfaction Equilibrium (ESE). Based on these approaches, different solutions and stable operation points are identified and their properties are analyzed. An in depth evaluation and comparison of the various obtained outcomes is achieved, via modeling and simulations. The focus is placed on the impact and the interplay of the NOMA specific features, including the potential over-exploitation of the available bandwidth, the fairness in accessing it, and the interference treatment. It is also shown that, using the satisfaction form games for the users to converge to the ESE, provides an efficient and promising user-centric modeling approach to the power allocation problem, as the system adapts to the users’ application needs, while at the same time eliminates a significant amount of interference.

The role of organization intermediaries in science-/techno-push versus user-centric approaches in health care innovation

PurposeHealth care ecosystems instantiate different innovation trajectories, driven either by science-/techno-push or user-centric rationales. This article focuses on organization intermediaries (OIs), respectively, active in health care ecosystems driven by science- and techno-push versus user-centric innovation processes; it aims at characterizing their operation and intervention modes. The analysis elaborates on network and content brokerage. Innovation also needs to consider various challenges associated with physical vicinity. The authors check whether territorial anchoring plays a role in brokerage, depending on the innovation model.Design/methodology/approachThe article offers an investigation of eight French organizations matching the definition of OIs and active in different areas of health care-related innovation. It follows a qualitative and abductive research protocol adhering to the precepts of grounded theory.FindingsFirst, the authors show that content and network brokerage specialize in specific activities in each innovation model. On network brokerage, the authors show that OIs foster the development of communities of practice in the science-/techno-push model, while they nurture communities of innovation in the user-centric model. Services materializing content brokerage are typical consequences of activities performed in each model. The second contribution deals with physical vicinity. In the science-/techno-push model, OIs install a physical space (the “internal” dimension) to support the development of communities of practice, while the “external” dimension copes with agglomeration effects. In the user-centric model, OIs deliver services thanks to the “internal” space; communities of innovation create a leverage effect on the physical space to operate their activities that are supported by “external” network effects.Originality/valueThe originality of the article lies in the description of the alternative roles plaid by organization intermediaries in the science-/techno-push versus user-centric approaches of innovation. In these two approaches, (contents and network) brokerage and physical vicinity play different roles.
