    Abstract [en]

    Health and social care is becoming ever more complex as a consequence of societal trends, including an aging population and increased reliance on care at home. One aspect of the increased complexity is that a single patient may receive care from several care providers, which easily results in situations with potentially incoherent, uncoordinated, and interfering care processes. In order to describe and analyze such situations, the article introduces the notions of patient-centered care process and a conglomeration of such. The latter is defined as a set of patient care processes that all concern the same patient, are overlapping in time, and are all sharing the overall goal of improving or maintaining the health and social well-being of the patient. The processes are based on a PDCA-cycle comprising phases for assessing, planning, performing and following up the care for the patient independently of health and social care organizations.

    Abstract [en]

    This paper discusses the fact that more and more patients are treated in their homes by a whole set of organizations, and how this fact places new and more intense demands on health and social care staff to communicate and collaborate. The aim of the paper is to further explore the detailed needs for collaboration between different care units, individuals and professions, and to outline organizational and/or IT-based solutions. The suggested solutions are based on a patient and process oriented perspective and on an analysis of needs and issues expressed in interviews with key actors in a number of research projects focused on collaboration in care. We point to the need for managers in different organizations to agree on ways of communicating and collaborating on the operational level over sectors and units and how this aspect has to be taken into account already during procurement of care services. Most importantly, by reasoning from a basic set of issues, we derive a set of related problems and suggest solutions for how to deal with these. The solutions include suggestions for various e-services aimed at improving coordination and collaboration among care personnel.

    Patterns-based Evaluation of Open Source BPM Systems: The Cases of jBPM, OpenWFE, and Enhydra Shark2007Report (Other academic)
    Abstract [en]

    The abundance of approaches towards business process specification and enactment is well-known and is an ongoing source of confusion. One of the objectives of the Workflow Patterns Initiative is to provide an insight into comparative strenghts and weaknesses of the state-of-the-art in Process Aware Information Systems. Over the past years many approaches to business process specification including commercial offerings, modelling languages, and academic prototypes have been evaluated in terms of the patterns in order to assess their capabilities in terms of expressing control-flow dependencies, data manipulation and resource allocation directives. With the increasing maturity and popularity of open source software it seems opportune to take a closer look at such offerings in the Business Process Management area. This report provides a patterns-based evaluation of three well-known open source workflow management systems: jBPM, OpenWFE, and Enhydra Shark.

    Abstract [en]

    In keeping with the proliferation of free software development initiatives and the increased interest in the business process management domain, many open source workflow and business process management systems have appeared during the last few years and are now under active development. This upsurge gives rise to two important questions: What are the capabilities of these systems? and How do they compare to each other and to their closed source counterparts? In other words: What is the state-of-the-art in the area?. To gain an insight into these questions, we have conducted an in-depth analysis of three of the major open source workflow management systems – jBPM, OpenWFE, and Enhydra Shark, the results of which are reported here. This analysis is based on the workflow patterns framework and provides a continuation of the series of evaluations performed using the same framework on closed source systems, business process modelling languages, and web-service composition standards. The results from evaluations of the three open source systems are compared with each other and also with the results from evaluations of three representative closed source systems: Staffware, WebSphere MQ, and Oracle BPEL PM. The overall conclusion is that open source systems are targeted more toward developers rather than business analysts. They generally provide less support for the patterns than closed source systems, particularly with respect to the resource perspective, i.e. the various ways in which work is distributed amongst business users and managed through to completion.

    Data-Centric Network of Things: A Method for Exploiting the Massive Amount of Heterogeneous Data of Internet of Things in Support of Services2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Internet of things (IoT) generates massive amount of heterogeneous data, which should be efficiently utilized to support services in different domains. Specifically, data need to be supplied to services by understanding the needs of services and by understanding the environment changes, so that necessary data can be provided efficiently but without overfeeding. However, it is still very difficult for IoT to fulfill such data supply with only the existing supports of communication, network, and infrastructure; while the most essential issues are still unaddressed, namely the heterogeneity issue, the recourse coordination issue, and the environments’ dynamicity issue. Thus, this necessitates to specifically study on those issues and to propose a method to utilize the massive amount of heterogeneous data to support services in different domains.

    This dissertation presents a novel method, called the data-centric network of things (DNT), which handles heterogeneity, coordinates resources, and understands the changing IoT entity relations in dynamic environments to supply data in support of services. As results, various services based on IoT (e.g., smart cities, smart transport, smart healthcare, smart homes, etc.) are supported by receiving enough necessary data without overfeeding.

    The contributions of the DNT to IoT and big data research are: firstly the DNT enables IoT to perceive data, resources, and the relations among IoT entities in dynamic environments. This perceptibility enhances IoT to handle the heterogeneity in different levels. Secondly, the DNT coordinates IoT edge resources to process and disseminate data based on the perceived results. This releases the big data pressure caused by centralized analytics to certain degrees. Thirdly, the DNT manages entity relations for data supply by handling the environment dynamicity. Finally, the DNT supply necessary data to satisfy different service needs, by avoiding either data-hungry or data-overfed status.

    An Ontology-based Problem-logic Driven Approach towards the Activity Awareness for Elderly Care2015In: International Journal of Multimedia and Ubiquitous Engineering, ISSN 1975-0080, Vol. 10, no 4, 31-42 p.Article in journal (Refereed)
    Abstract [en]

    The same activity under different user situations in the elderly care system may lead to different intelligent system response, since user needs vary with the changing situations. Activity awareness (AA) emphasizes that systems intelligently respond to user needs by aware the user-performed activities which is denoted and comprehended according to various user situations. But most current AA technics use similar patterns retrieved from the growing historical data, neglecting the situation change, called dataset driven. Thus, an aptly approach is needed in support of AA systems to handle various activity denotations in different user situations. Responding to the problem, this paper proposes an Ontology-based Problem-logic driven approach (OPL) to enhance the AA system by denoting user activities with the problem logic according to user-oriented denoted problem domains, where the AA system can seamlessly integrate with inferring for intelligent system response. Specifically, denoted problem domain and logic are proposed to support the OPL concepts, while activity graph is formed to support the intelligent system response based on the annotated problem logic. With the OPL, systems can directly target at the changing situations with rule-based inferring. A case study is performed upon the scenario retrieved from a European elderly care project, where a proof-of-concept prototype is established to confirm the validity of the OPL approach.

    Constructing Context-centric Data Objects to Enhance Logical Associations for IoT Entities2015In: Procedia Computer Science, ISSN 1877-0509, E-ISSN 1877-0509, Vol. 52, 1095-1100 p.Article in journal (Refereed)
    Abstract [en]

    Entities in Internet of Things (IoT) need intelligent associations to allow a flexible and dynamic system reaction towards varying user situations. Purely data-oriented association methods (e.g., data-mining, machine-learning, etc.) are limited in deduction from existing associations. Also such data-oriented methods are limited in accuracy for working with small-scale datasets (e.g., working with patterns retrieved from historical data), outputting associations based on statistics rather than logic. Moreover, existing semantic technologies (ontological-oriented or rule-oriented) are facing with either flexibility or dynamicity challenges to discover and maintain the associations. This paper proposes an alternative technique of semantically constructing context-centric data objects based on service logics for logical associations, which enables an event net based on association nets adapting for the changing situations (called context-centric). A proof-of-concept implementation is carried out based on a vehicle planning scenario to validate the data construction technique. Comparing to previous work, this technique possesses advantages of flexibility and dynamicity for entity associations based on service logics.

    Generic Distributed Sensing in Support of Context Awareness in Ambient Assisted Living2014In: Multimedia and Ubiquitous Engineering / [ed] Park, J. J.; Chen, S. C.; Gil, J. M.; Yen, N. Y., Springer Berlin/Heidelberg, 2014, 99-107 p.Conference paper (Refereed)
    Abstract [en]

    Researches in ambient assisted living have so far faced three important challenges: (1) Lack of a comprehensive approach to capture user needs that are generic; i.e., not limited to specific events, but as generic related to the user. (2) Lack of a highly flexible and scalable platform for the distributed sharing and processing of context between nodes in IoT networks. (3) Increased amount of communication and devices with sensors participating in the acquisition, processing and sharing of context further challenges both computation capability and storage capacity of the system. In this paper, we address these limitations and present novel support, applied in a system for remote assistance of elderly. The support comprehensively retrieves user needs from generic context, via a scalable overlay providing increment of processing capability and storage. Further, the support self-organizes entities into generic context from distributed sensing, using the Dependent Context Pattern (DCP) based on the Context Virtualizing Platform (CVP).

    Logical interactions for heterogeneous IoT entities via virtual world mirrors in support of Ambient Assisted Living2016In: Journal of Ambient Intelligence and Smart Environments, ISSN 1876-1364, E-ISSN 1876-1372, Vol. 8, no 5, 565-580 p.Article in journal (Refereed)
    Abstract [en]

    In Ambient Assisted Living (AAL), as an important applied area of Internet of Things (IoT) technology, logical entity interaction establishes an intelligent virtual world in which heterogeneous entities are emulated by object-oriented mirrors through tightly cooperating sensors and actuators from different spaces in the real world; this enables the system to generate intelligent services to support human behaviour. However, until now, few researchers have focused on enabling interactions between heterogeneous IoT entities for AAL services. Further, in relevant studies regarding semantic entity interactions, researchers have mainly focused on enabling semantic interactions between sensors (rather than integral entities) for the purpose of coordinating and managing data resources, where tight collaborations between sensors and actuators are not emphasised. Hence, the system capability of initialising intelligent service to enhance human experience has not been properly emphasised, to date. This paper discusses enabling logical object-oriented IoT entity interactions to enrich AAL services for humans through the creation of mirrors in the virtual world emulating the attributes and behaviours of heterogeneous entities via cooperating sensors and actuators in the real world. This paper introduces the Entity Device Collocating (EDC) Platform to globally locate and retrieve sensors and actuators respectively adhering to the attributes and behaviours of integral mirrors in the virtual world; this is intended to enable the interoperability between virtual and real worlds. Interactions are created upon entity mirrors mapping entities from the physical world to the virtual world, during which interactions continue to evolve based on the service logics. The proposed technique is applied to a typical AAL case of smart pill-ingestion, where a demo is implemented for verification. Comparing with relevant research, the proposed technique contributes by introducing a flexible and scalable IoT entity interaction method targeting AAL to address human needs.

    Intelligent Data-Intensive IoT: A Survey2016In: 2016 2nd IEEE International Conference on Computer and Communications (ICCC): Proceedings, IEEE Computer Society, 2016, 2362-2368 p.Conference paper (Refereed)
    Abstract [en]

    The IoT paradigm proposes to connect entities intelligently with massive heterogeneous nature, which forms an ocean of devices and data whose complexity and volume are incremental with time. Different from the general big data or IoT, the data-intensive feature of IoT introduces several specific challenges, such as circumstance dynamicity and uncertainties. Hence,intelligence techniques are needed in solving the problems brought by the data intensity. Until recent, there are many different views to handle IoT data and different intelligence enablers for IoT, with different contributions and different targets. However, there are still some issues have not been considered. This paper will provide a fresh survey study on the data-intensive IoT issue. Besides that, we conclude some shadow issues that have not been emphasized, which are interesting for the future. We propose also an extended big data model for intelligent data-intensive IoT to tackle the challenges.

    Edge-based interoperable service-driven information distribution for intelligent pervasive services2017In: Pervasive and Mobile Computing, ISSN 1574-1192, E-ISSN 1873-1589, Vol. 40, 359-381 p.Article in journal (Refereed)
    Abstract [en]

    Internet of Things (IoT)-based Intelligent Pervasive Service (IPS) systems face increasing pressure from the massive amounts of heterogeneous data generated; the heterogeneity hinders interoperability between data resources and IPSs, making data sharing inefficient and making it difficult to satisfy the needs and fulfill requirements of the IPSs. In response, this article proposes a method of interoperable service-driven information distribution on the edge side to enhance the service-level interoperability with feature-level interoperability by self-adapting data sharing according to the service needs, which will also help to release incremental data pressure and provide better data privacy by conducting service-driven and relevance-based data sharing.

    “Canderoid”: A mobile system to remotely monitor travelling status of the elderly with dementia2013In: International Joint Conference on Awareness Science and Technology and Ubi-Media Computing (iCAST-UMEDIA), 2013, IEEE Press , 2013, 648-654 p.Conference paper (Refereed)
    Abstract [en]

    The number of elderly people increases quickly in many countries, under the global population aging situation. It is an upsetting fact that many elderly people are suffering from the dementia, which seriously obstructs their independent living and travel. It is a pervasive problem that the demented elderly individuals are easy to get lost or go into danger during alone travel in daily life. Therefore we propose a novel mobile system named “Canderoid” to monitor independent outdoor travel of the elderly individuals remotely, with aid from the caretaker. The system is composed mainly of an android terminal (Wanderoid), an MQTT broker, and a platform on caretaker side. In the system, an android terminal named “Wanderoid” is implemented on a smartphone to capture the travelling status, using built-in smartphone sensors (i.e. camera with an adhesive fish-eye lens, compass and GPS). The terminal device is a normal smartphone, with a fish-eye lens attached on the camera. The sensor data are transferred to the platform of caretaker after capturing. The data transmission work relies on a message pushing architecture, which deals with mobile IP address changing and enables remote manipulation of the smartphone terminal, by introducing the MQTT broker. Then the caretaker platform can interpret sensor data and real-timely present the travelling status using snapshot taken by the fish-eye camera, street view and map. A reliability test, energy dissipation test and usability test are carried out on the prototype to verify that the system is effective, easy-to-use, reliable and energy-saving, from the viewpoints of both technology and human factors.

    The easy and widely accessibility of Internet resources makes it possible to support learning almost anywhere at any time through powerful mobile technologies, and facilitate ubiquitous learning (u-learning) to grow in use and popularity. Augmented Reality (AR) can be recognized as a key technology that can be used in the U-learning environment to increase learning effect and improve learning experience. This paper designs an integrated model of U-learning, based on which we have also developed an augmented reality technology based learning system named as “Starry Sky Exploration—Eight Planets of Solar System”; an analysis on its implementation is reported and the AR learning system applicable for U-learning environment is found effective and practical.

    Fossil-free Public Transport: Prescriptive Policy Analysis for the Swedish Bus Fleets2016In: 2016 13th International Conference on the European Energy Market (EEM), IEEE Computer Society, 2016Conference paper (Refereed)
    Abstract [en]

    Elicitation and processing of the relevant information is the core of any policy decision-making process. This study presents a prescriptive policy analysis for the “fossil-free fuel deployment for public transport buses at the national level in Sweden”, using a policy-oriented modelling and simulation tool, Sense4us , that supports systems analysis for policy involving:: (i) Structuring of policy problems using the labelled causal mapping method [11], (ii) Ex ante Impact assessment using scenario-based dynamic simulation modelling and (iii) Ex-ante evaluation of the considered policy options based on the simulation results and using a set of standard criteria for evaluation of EU policy interventions. The results are most of all useful for designing a policy pathway for public bus transport that is both environmentally sustainable and economically feasible. Moreover, the process allows involvement of the key stakeholders to reflect various priorities and preferences.

    Factors Influencing Productization of Enterprise Modeling: A Qualitative Inquiry into the Scandinavian Strand of Methods and Tools2015In: The Practice of Enterprise Modeling, 8th IFIP WG 8.1. Working Conference, PoEM 2015, Valencia, Spain, November 10–12, 2015, Springer , 2015Conference paper (Refereed)
    Abstract [en]

    Enterprise Modeling (EM) methods and tools have been developed and successfully used for more than two decades yet their adoption in organizations is mostly ad hoc. Only a few EM methods and tools have become successful products despite being theoretically sound and having certain success in application in practice. This grounded theory inquiry ponders on what factors influence the successful productization of EM methods and tools. Among the factors discussed are EM maturity gap, method and tool development process, application context, marketing and sales aspects, as well as product aspects.

    Abstract [en]

    This paper is largely based on a state of the art report covering the information security (IS) metrics area produced as part of the Controlled Information Security (COINS) research project funded by the Swedish Civil Contingencies Agency (MSB) and the comprehensive literature review conducted while compiling the report. The report's findings are summarized and some of the key issues discovered in the course of the literature review are reflected upon. Additionally, the paper describes a conceptual systemic scheme/model for the research process, while explaining its relevance to the subject area, that may help with resolution of the outlined issues in future research in the area. The paper is written principally with a management/governance (rather than engineering) perspective in mind.

    Mining Mozambique Health Data: The Case of Malaria: From Bayesian Incidence Risk to Incidence Case Predictions2015Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The health sector in Mozambique is piled with data, holding records of major public health diseases, such as malaria, cholera, etc. The process of scrutinizing such a mass of health data for useful information is challenging but essential for the health authorities and professionals. Statistical learning and inferential approaches can be used to provide health decision makers with appropriate tools for disease diagnosis and assessment, where the analysis is performed using Bayesian predictive techniques and data mining. The purpose of this thesis is to investigate how predictive data mining and Bayesian regression methods can be used effectively, so as to extract useful knowledge from reported malaria health data to support decision making and management. 

    In summary, effective Bayesian predictive methods based on spatial and space-time reported cases of malaria have been derived, allowing the extraction of the main risk factors for malaria. Predictive models that combine consecutive temporal connections within the analysis of the space-time variations of the disease have been found to be relevant when the explicit modeling of seasonality is not required or is even unfeasible.

    Investigation of the most effective ways to derive numerical predictive models was performed using several regression predictive methods. The conclusions are that effective numerical prediction of new cases of the disease can be achieved by training support vector machines using a time-window approach for the choice of different training sets based on a number of years and reducing the time towards the test set. The best performance is obtained for a smaller time-window. Another contribution of this thesis is the determining of the importance of predictors in the prediction of the incidence of malaria, performed by adopting the permutation accuracy strategy (from the random forests method) using the test set. Also, an additional contribution relates to a significant reduction in the predictive error, which has been obtained by the employment of a sample correction bias strategy, while testing the predictive models in different regions, other than where they were initially developed.

    Mapping malaria incidence distribution that accounts for environmental factors in Maputo Province - Mozambique2010In: Malaria Journal, ISSN 1475-2875, E-ISSN 1475-2875, Vol. 9, 79Article in journal (Refereed)
    Abstract [en]

    Background: The objective was to study if an association exists between the incidence of malaria and some weather parameters in tropical Maputo province, Mozambique. Methods: A Bayesian hierarchical model to malaria count data aggregated at district level over a two years period is formulated. This model made it possible to account for spatial area variations. The model was extended to include environmental covariates temperature and rainfall. Study period was then divided into two climate conditions: rainy and dry seasons. The incidences of malaria between the two seasons were compared. Parameter estimation and inference were carried out using MCMC simulation techniques based on Poisson variation. Model comparisons are made using DIC. Results: For winter season, in 2001 the temperature covariate with estimated value of -8.88 shows no association to malaria incidence. In year 2002, the parameter estimation of the same covariate resulted in 5.498 of positive level of association. In both years rainfall covariate determines no dependency to malaria incidence. Malaria transmission is higher in wet season with both covariates positively related to malaria with posterior means 1.99 and 2.83 in year 2001. For 2002 only temperature is associated to malaria incidence with estimated value 2.23. Conclusions: The incidence of malaria in year 2001, presents an independent spatial pattern for temperature in summer and for rainfall in winter seasons respectively. In year 2002 temperature determines the spatial pattern of malaria incidence in the region. Temperature influences the model in cases where both covariates are introduced in winter and summer season. Its influence is extended to the summer model with temperature covariate only. It is reasonable to state that with the occurrence of high temperatures, malaria incidence had certainly escalated in this year.

    Spatial and temporal patterns of malaria incidence in Mozambique2011In: Malaria Journal, ISSN 1475-2875, E-ISSN 1475-2875, Vol. 10, 189Article in journal (Refereed)
    Abstract [en]

    Background: The objective of this study is to analyze the spatial and temporal patterns of malaria incidence as to determine the means by which climatic factors such as temperature, rainfall and humidity affect its distribution in Maputo province, Mozambique. Methods: This study presents a model of malaria that evolves in space and time in Maputo province-Mozambique, over a ten years period (1999-2008). The model incorporates malaria cases and their relation to environmental variables. Due to incompleteness of climatic data, a multiple imputation technique is employed. Additionally, the whole province is interpolated through a Gaussian process. This method overcomes the misalignment problem of environmental variables (available at meteorological stations points) and malaria cases (available as aggregates for every district - area). Markov Chain Monte Carlo (MCMC) methods are used to obtain posterior inference and Deviance Information Criteria (DIC) to perform model comparison. Results: A Bayesian model with interaction terms was found to be the best fitted model. Malaria incidence was associated to humidity and maximum temperature. Malaria risk increased with maximum temperature over 28 degrees C (relative risk (RR) of 0.0060 and 95% Bayesian credible interval (CI) of 0.00033-0.0095) and humidity (relative risk (RR) of 0.00741 and 95% Bayesian CI 0.005141-0.0093). The results would suggest that additional non-climatic factors including socio-economic status, elevation, etc. also influence malaria transmission in Mozambique. Conclusions: These results demonstrate the potential of climate predictors particularly, humidity and maximum temperature in explaining malaria incidence risk for the studied period in Maputo province. Smoothed maps obtained as monthly average of malaria incidence allowed to visualize months of initial and peak transmission. They also illustrate a variation on malaria incidence risk that might not be related to climatic factors. However, these factors are still determinant for malaria transmission and intensity in the region.

    Comparing Support Vector Regression and Random Forests for Predicting Malaria Incidence in Mozambique2013In: 2013 International Conference on Advances in ICT for Emerging Regions (ICTer), IEEE Computer Society, 2013, 217-221 p.Conference paper (Refereed)
    Abstract [en]

    Accurate prediction of malaria incidence is essentialfor the management of several activities in the ministry of health in Mozambique. This study investigates the comparison ofsupport vector machines (SVMs) and random forests (RFs) forthis purpose. A dataset with records of malaria cases covering theperiod 1999-2008 was used to evaluate predictive models on thelast year when developed from one up to nine years of historicaldata. Mean squared error (MSE) was used as performancemetric. The scheme for estimating variable importance commonlyemployed for RFs was also adopted for SVMs. SVMs developedfrom two year of historical data obtained the best predictionaccuracy. Hence, if we are interested in predicting the actualnumber of malaria cases the support vector machines modelshould be chosen. In the analysis of variable importance, IndoorResidual Spray (IRS), the districts of Manhiça and Matola andmonth of January turned out to be the most important predictorsin both the SVM and RF models.

    Generalization of Malaria Incidence Prediction Models by Correcting Sample Selection Bias2013In: Advanced Data Mining and Applications: Proceedings, Part II / [ed] Hiroshi Motoda et al., Springer Berlin/Heidelberg, 2013, 189-200 p.Conference paper (Refereed)
    Abstract [en]

    Performance measurements obtained from dividing a single sample into training and test sets, e.g. by employing cross-validation, may not give an accurate picture of the performance of any model developed from the sample, on the set of examples to which the model will be applied. Such measurements, which are due to that training and test samples are drawn according to different distributions may hence be misleading. In this study, two support vector machine models for predicting malaria incidence developed from certain regions and time periods in Mozambique are evaluated on data from novel regions and time periods, and the use of selection bias correction is investigated. It is observed that significant reductions in the predicted error can be obtained using the latter approach, strongly suggesting that techniques of this kind should be employed if test data can be expected to be drawn from some other distribution than what is the origin of the training data.

    Predicting the Incidence of Malaria Cases in Mozambique Using Regression Trees and Forests2013In: International Journal of Computer Science and Electronics Engineering (IJCSEE), ISSN 2320-401X, Vol. 1, no 1, 50-54 p.Article in journal (Refereed)
    Abstract [en]

    Malaria remains a significant public health concern in Mozambique with disease cases reported in almost every province. This study investigates the prediction models of the number of malaria cases in districts of Maputo province. Used data include administrative districts, malaria cases, indoor residual spray and climatic variables temperature, rainfall and humidity. Regression trees and random forest models were developed using the statistical tool R, and applied to predict the number of malaria cases during one year, based on observations from preceding years. Models were compared with respect to the mean squared error (MSE) and correlation coefficient. Indoor Residual Spray (IRS), month of January, minimal temperature and rainfall variables were found to be the most important factors when predicting the number of malaria cases, with some districts showing high malaria incidence. Additionally, by reducing the time window for what historical data to take into account, predictive performance can be increased substantially.

    Strengthening the Health Information System in Mozambique through Malaria Incidence Prediction2013In: IST-Africa 2013 Conference Proceedings / [ed] Paul Cunningham, Miriam Cunningham, IEEE Computer Society, 2013, 1-7 p.Conference paper (Refereed)
    Abstract [en]

    Malaria is one of the principal health problems in Mozambique, affecting mostly children. The prediction of accurate future incidence cases is crucial for the implementation of appropriate policies of intervention and disease control in order to strengthen the health system. We propose a model based on support vector machines (SVM) for predicting yearly malaria incidence cases for children 0-4 years of age in the Maputo province, Mozambique. The predictive model is trained on two years of historical malaria data in combination with climatic and malaria control factors. A grid optimization parameter tuning procedure was firstly employed to detect the best parameters and select the kernel. In order to determine the most influential factors, variable importance was calculated through estimating the impact of permuting feature values on the predictive performance. The most important malaria incidence predictors turned out to be temperature variation, followed by Matutuine (district), April (month) and Namaacha (district).

    Comparison of infant malaria incidence in districts of Maputo province, Mozambique2011In: Malaria Journal, ISSN 1475-2875, E-ISSN 1475-2875, Vol. 10, 93Article in journal (Refereed)
    Abstract [en]

    Background: Malaria is one of the principal health problems in Mozambique, representing 48% of total external consultations and 63% of paediatric hospital admissions in rural and general hospitals with 26.7% of total mortality. Plasmodium falciparum is responsible for 90% of all infections being also the species associated with most severe cases. The aim of this study was to identify zones of high malaria risk, showing their spatially and temporal pattern. Methods: Space and time Poison model for the analysis of malaria data is proposed. This model allows for the inclusion of environmental factors: rainfall, temperature and humidity as predictor variables. Modelling and inference use the fully Bayesian approach via Markov Chain Monte Carlo (MCMC) simulation techniques. The methodology is applied to analyse paediatric data arising from districts of Maputo province, Mozambique, between 2007 and 2008. Results: Malaria incidence risk is greater for children in districts of Manhica, Matola and Magude. Rainfall and humidity are significant predictors of malaria incidence. The risk increased with rainfall (relative risk - RR: .006761, 95% interval: .001874, .01304), and humidity (RR: .049, 95% interval: .03048, .06531). Malaria incidence was found to be independent of temperature. Conclusions: The model revealed a spatial and temporal pattern of malaria incidence. These patterns were found to exhibit a stable malaria transmission in most non-coastal districts. The findings may be useful for malaria control, planning and management.

    How to Stay in the Emotional Rollercoaster: Lessons Learnt from Designing EmRoll2010In: NordiCHI, ACM Press , 2010Conference paper (Other academic)
    Abstract [en]
    Bodily expressions can be used to involve players in intense experiences with games. By physically moving, breathing, or increasing your pulse, you may start emotional processes that help create for a stronger experience of the narrative in the game. We have designed a system named EmRoll that poses riddles to pairs of players. The riddles can only be solved if the players are, or at least pretend to be, moving according to different emotional states: dancing happily, relaxed breathing and being scared. The system measures movement, breathing and sweat reactions from the two players. Lessons learnt were: playing in pairs is an impor- tant aspect as the two players influenced one-another, pull- ing each other into stronger experiences; getting excited through intense movement when involving your whole body worked well, as did relaxing through deep breathing; using the sweat response as an input mechanism worked less well; and finally, putting a Wizard (a human operator) into the loop can help bootstrap difficulty balancing and thereby increase emotional involvement.

    Impact of the virtual patient introduction on the clinical reasoning process in dental education2012In: Bio-Algorithms and Med-Systems, ISSN 1895-9091, Vol. 8Article in journal (Refereed)
    Abstract [en]

    Background In the Virtual patient system Web-SP, the case authoring is entirely delegated to faculty. An analysis of the virtual patients (VPs) authored by faculty showed that the most common practice chosen by the case authors was to provide an introductory clinical vignette including rich anamnestic data. To evaluate the influence of the vignette, a controlled trial was conducted to determine if the absence of vignette would influence the students' therapeutic decisions and their clinical reasoning. Methods This double blind controlled trial randomized 57 fourth year dentistry students into two groups. Two virtual patient cases were created with the same content in both groups, but the VPs encountered by the intervention group lacked the introductory vignette. The therapy decisions and the history taking activity were scored and analysed by the course director. A stratified analysis was undertaken, stratifying by day. Results There were no statistically significant differences between the two groups with respect to their therapeutic decision scores (p=.16). Participants in both groups were equivalent with respect to the number of relevant medical history questions asked (p=.33) and the number of irrelevant questions asked (p=.20) Conclusions This study indicates that vignettes did not have an impact on students' clinical reasoning process. The use of detailed vignettes or case introductions might not be needed. A possible reason includes students' prior exposure for a full semester to other VPs for course work and clinical reasoning. Perhaps the intervention was too subtle to impact on learners at this stage of development. Clinical vignettes might have more impact at earlier stages of student learning such as early in the semester but not as preparation for final exam. The limited number of participants may have concealed differences between the groups. We also need to investigate if the one-hour limit given the students might influence the therapeutic decisions.
