Agile contracts and pricing models in public procurements of information systems. Process of public information system procurement has been overlooked in information system science. Especially empirical study of contract types and pricing models that support agile development has been neglected. The aim of this research is to fill this research gap. The research question is how agile contracts and pricing models can be applied in public procurements of information systems. This research investigates what ways and practices for implementing agile contracts and pricing models exist in public sector. The approach of this research is qualitative. The research question will be answered by analyz…

Physical activity and sedentary time in relation to academic achievement in children

2017

Objectives To investigate the independent and combined associations of objectively measured moderate-to-vigorous physical activity (MVPA) and sedentary time (ST) with reading and arithmetic skills. Design Cross-sectional/prospective. Methods Participants were 89 boys and 69 girls aged 6–8 years. MVPA and ST were measured using a combined heart rate and movement sensor and body fat percentage by dual-energy X-ray absorptiometry in Grade 1. Reading fluency, reading comprehension, and arithmetic skills were assessed using standardized tests in Grades 1–3. The data were analyzed using linear regression analyses and analyses of covariance with repeated measures. Results In boys, MVPA was directl…

Ramy i modele jakości informacji - próba porównania

2016

Celem artykułu było przedstawienie i porównanie najważniejszych ram i modeli jakości informacji wyróżnionych w literaturze przedmiotu. Spośród licznych modeli zaprezentowano trzy: model R Wanga, model B Kahna, D.Strong i R. Wanga oraz model M. Epplera. Pokazano, że porównanie modeli i ram jakości informacji jest możliwe na podstawie zestawu kryteriów obejmujących: ogólność, odpowiedniość, elastyczność i kompletność. Wykazano, że biorąc pod uwagę wymienione kryteria, za najlepszy należy uznać model ram jakości przedstawiony przez M. Epplera. Jednak i ten model nie spełnia wszystkich tych kryteriów, gdyż nie jest kompletny pod względem prezentacji relacji między atrybutami jakości informacji,…

Sauna bathing is associated with reduced cardiovascular mortality and improves risk prediction in men and women: a prospective cohort study.

2018

Background Previous evidence indicates that sauna bathing is related to a reduced risk of fatal cardiovascular disease (CVD) events in men. The aim of this study was to investigate the relationship between sauna habits and CVD mortality in men and women, and whether adding information on sauna habits to conventional cardiovascular risk factors is associated with improvement in prediction of CVD mortality risk. Methods Sauna bathing habits were assessed at baseline in a sample of 1688 participants (mean age 63; range 53–74 years), of whom 51.4% were women. Multivariable-adjusted hazard ratios (HRs) were calculated to investigate the relationships of frequency and duration of sauna use with C…

Lake Load Response (LLR) – mallityökalu vesialueiden hoidon suunnittelun apuvälineenä

2010

For eutrophic lakes, achieving good water quality usually requires a reduction in external loading. The Lake Load Response (LLR) tool, based on the LakeState (LS) model, can be used to predict the necessary loading reduction, which can be utilized when making decisions on the management of the lake. The best predictions are made when the input values of the incoming loading, water outflow and in-lake total phosphorus, total nitrogen and chlorophyll a concentrations are as accurate as possible. Accurate loading data is often hard to collect because of the lack of resources for observations. However, LLR-runs made for the lake Lehesjärvi-Vähäjärvi in Jyväskylä showed that examining the needed…

Antipredatory function of head shape for vipers and their mimics.

2011

Most research into the adaptive significance of warning signals has focused on the colouration and patterns of prey animals. However, behaviour, odour and body shape can also have signal functions and thereby reduce predators' willingness to attack defended prey. European vipers all have a distinctive triangular head shape; and they are all venomous. Several non-venomous snakes, including the subfamily Natricinae, commonly flatten their heads (also known as head triangulation) when disturbed. The adaptive significance of this potential behavioural mimicry has never been investigated. We experimentally tested if the triangular head shape typical of vipers offers protection against predation.…

Requirements for using simulation to design and assess wireless ATM handover solutions

1999

Wireless ATM (WATM) has been widely considered as a solution for broadband wireless services. Handover is one of the most important mobility support functions in the WATM network. Many handover solutions have been proposed, analysed, and benchmarked. Simulations have been broadly used to assess these solutions. However, there are many dilemmas in how simulation has been applied as a research methodology: heterogeneous simulation systems used, lack of comparison with other related work, biased conclusions, and unavailability of simulation models and systems to researchers. The WATM research community lacks a standard and commonly acceptable methodology for applying simulation. To address thi…

3D DIGITAL MODELS FOR A WIDESPREAD MUSEUM: THE RENON’S “BAUERNHÖFE”

2019

Abstract. The aim of the paper is to study the characteristics of different 3D digital models (point clouds, mesh, CSG, BIM) for the realization of a museum of historical buildings widespread in the territory of South Tyrol through the 3D modeling of several farmhouses between the towns of Collalbo, Longomoso and Siffiano, in the Renon area. Therefore, moving from a defined case study, the paper proposes a workflow for model choice, use, and sharing considering also users profile.The objective is to create a system that allows, the sharing, both on site and remotely, of farmhouses digital models, information, images and documents found during the research. The purpose is to enhance the terr…
