An Adaptive Global-Local Memetic Algorithm to Discover Resources in P2P Networks
2007
This paper proposes a neural network based approach for solving the resource discovery problem in Peer to Peer (P2P) networks and an Adaptive Global Local Memetic Algorithm (AGLMA) for performing the training of the neural network. This training is very challenging due to the large number of weights and noise caused by the dynamic neural network testing. The AGLMA is a memetic algorithm consisting of an evolutionary framework which adaptively employs two local searchers having different exploration logic and pivot rules. Furthermore, the AGLMA makes an adaptive noise compensation by means of explicit averaging on the fitness values and a dynamic population sizing which aims to follow the ne…
A Memetic-Neural Approach to Discover Resources in P2P Networks
2008
This chapter proposes a neural network based approach for solving the resource discovery problem in Peer to Peer (P2P) networks and an Adaptive Global Local Memetic Algorithm (AGLMA) for performing in training of the neural network. The neural network, which is a multi-layer perceptron neural network, allows the P2P nodes to efficiently locate resources desired by the user. The necessity of testing the network in various working conditions, aiming to obtain a robust neural network, introduces noise in the objective function. The AGLMA is a memetic algorithm which employs two local search algorithms adaptively activated by an evolutionary framework. These local searchers, having different fe…
A simulation of disagreement for control of rational cheating in peer review
2013
Understanding the peer review process could help research and shed light on the mechanisms that underlie crowdsourcing. In this paper, we present an agent-based model of peer review built on three entities - the paper, the scientist and the conference. The system is implemented on a BDI platform (Jason) that allows to define a rich model of scoring, evaluating and selecting papers for conferences. Then, we propose a programme committee update mechanism based on disagreement control that is able to remove reviewers applying a strategy aimed to prevent papers better than their own to be accepted (rational cheating). We analyze a homogeneous scenario, where all conferences aim to the same leve…
Models of E-Democracy
2006
Pulished article in Communications of the Association for Information Systems, 17 (1), 818-840. Also available from the publisher: http://aisel.aisnet.org/cais/vol17/iss1/37/ Several theories of E-Democracy have been presented, and implementations of and experiments in E-Democracy emerged. However, existing literature on the subject appears rather non-comprehensive, lacking an integrated basis, for gathering knowledge in the future. After an analysis of theories of E-Democracy versus implementations reported in related literature, we address the need for a model generally absent from contemporary theoretical literature: the Partisan model of E-Democracy. We aim to simplify the current "jung…
Managing Benefits in the Public Sector. Surveying Expectations and Outcomes in Norwegian Government Agencies
2008
Published version of a chapter in Lecture Notes in Computer Science, 5184, 98-110. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-540-85204-9_9 Government agencies currently experience increasing pressure to document benefits from spending on eGovernment efforts. Hence, structured methods for benefits management (BM) are being developed. However, hardly any studies have investigated how such approaches are used and experienced. This study addresses this practice-research gap by reporting a study of a project involving 30 Norwegian government agencies using a common BM approach.A questionnaire was answered by project managers. Results show that that some 80 % of the ma…
Predatory Open-Access Publishing in Anesthesiology.
2018
Predatory publishing is an exploitative fraudulent open-access publishing model that applies charges under the pretense of legitimate publishing operations without actually providing the editorial services associated with legitimate journals. The aim of this study was to analyze this phenomenon in the field of anesthesiology and related specialties (intensive care, critical and respiratory medicine, pain medicine, and emergency care). Two authors independently surveyed a freely accessible, constantly updated version of the original Beall lists of potential, possible, or probable predatory publishers and standalone journals. We identified 212 journals from 83 publishers, and the total number…
Traditional and professional birth attendants influence on womens decisions of birth place and type of birth assistance : a qualitative study in Tang…
2012
Author's version of an article in the journal: Nordisk Sygeplejeforskning. Also available from the publisher at: http://www.idunn.no/ts/nsf/2012/01/art02 Almost half of all Tanzanian women deliver at home, alone, assisted by family members or traditional birth attendants. The aim of this article was to expand existing knowledge on how pregnant and laboring women's preferences and decisions of birth place and type of assistance are influenced. A qualitative study with semi-structured interviews, with two traditional birth attendants and one midwife, and a participatory observation was conducted at a health clinic in Tanga District, Tanzania. It was found that the interaction between pregnant…
Adolescents' school-related self-concept mediates motor skills and psychosocial well-being.
2014
Background The health benefits of exercise participation and physical activity for mental health and psychosocial well-being (PSWB) have been shown in several studies. However, one important background factor, that is, motor skills (MSs), has largely been ignored. In addition, most of the existing research focuses on poor MSs, that is, poor MSs are often connected to poorer PSWB. The mechanism linking MSs and PSWB is unclear. However, a preliminary suggestion has been made that self-worth or self-perceptions might mediate the association between MSs and PSWB. Aim We investigated whether the self-concepts (SCs) of school-related physical education (SCPE), reading (SCR), and mathematics (SCM)…
An Information Systems Design Product Theory for Software Project Estimation and Measurement Systems
2009
There is relatively little research on software Project Estimation and Measurement Systems (PEMS). Commercial PEMS vary in functionality and effective- ness. Their intended users thus do not know what to ex- pect from PEMS and how to evaluate them. This paper creates an information system design product theory for the class of PEMS that prescribes the meta-requirements, the meta-design, and applicable theories for all products within the class. Meta-requirements and the meta-design are derived from the project estimation and measurement literature, experiences obtained during more than ten years of empirical work in Finnish Software Measurement Association, and a commercially available PEMS.
