Predicting hospital associated disability from imbalanced data using supervised learning.

2019

Hospitalization of elderly patients can lead to serious adverse effects on their functional capability. Identifying the underlying factors leading to such adverse effects is an active area of medical research. The purpose of the current paper is to show the potential of artificial intelligence in the form of machine learning to complement the existing medical research. This is accomplished by studying the outcome of hospitalization of elderly patients as a supervised learning task. A rich set of features characterizing the medical and social situation of elderly patients is leveraged and using confusion matrices, association rule mining, and two different classes of supervised learning algo…

Social–ecological connections across land, water, and sea demand a reprioritization of environmental management

2022

International audience; Despite many sectors of society striving for sustainability in environmental management, humans often fail to identify and act on the connections and processes responsible for social-ecological tipping points. Part of the problem is the fracturing of environmental management and social-ecological research into ecosystem domains (land, freshwater, and sea), each with different scales and resolution of data acquisition and distinct management approaches. We present a perspective on the social-ecological connections across ecosystem domains that emphasize the need for management reprioritization to effectively connect these domains. We identify critical nexus points rel…

Compact two-electron wave function for bond dissociation and Van der Waals interactions: A natural amplitude assessment

2014

Electron correlations in molecules can be divided in short range dynamical correlations, long range Van der Waals type interactions and near degeneracy static correlations. In this work we analyze for a one-dimensional model of a two-electron system how these three types of correlations can be incorporated in a simple wave function of restricted functional form consisting of an orbital product multiplied by a single correlation function $f(r_{12})$ depending on the interelectronic distance $r_{12}$. Since the three types of correlations mentioned lead to different signatures in terms of the natural orbital (NO) amplitudes in two-electron systems we make an analysis of the wave function in t…

Voices behind and beyond the label : the master narrative of ADHD (de)constructed by diagnosed children and their parents

2016

Artikkeliväitöskirja. Sisältää yhteenveto-osan ja neljä artikkelia. Article dissertation. Contains an introduction part and four articles. The dominant understanding of attention deficit hyperactivity disorder (ADHD) is that of diagnosed children “suffering” from neurodevelopmental condition owing to which they are prone to develop adverse life trajectories. This master narrative of ADHD and psychomedical and normative discourses it adheres to and employs have been integrated into the daily activities of homes and schools. This compilation dissertation study employs a social constructionist discourse framework and is located in the intersection of the disciplines of disability studies and s…

Organizational information and communication technologies and their influence on communication visibility and perceived proximity

2021

This study investigates the relationships between the use of various organizational ICTs, communication visibility, and perceived proximity to distant colleagues. In addition, this study examines the interplay between visibility and proximity, to determine whether visibility improves proximity, or vice versa. These relationships are tested in a global company using two waves of panel survey data. ESM use increases communication visibility and perceived proximity, while controlling for prior levels of visibility, proximity, and the use of other organizational ICTs. The influence of ESM on network translucence and perceived proximity is generally stronger than the impact of other technologie…

Multitasking in Driving as Optimal Adaptation Under Uncertainty

2021

Objective The objective was to better understand how people adapt multitasking behavior when circumstances in driving change and how safe versus unsafe behaviors emerge. Background Multitasking strategies in driving adapt to changes in the task environment, but the cognitive mechanisms of this adaptation are not well known. Missing is a unifying account to explain the joint contribution of task constraints, goals, cognitive capabilities, and beliefs about the driving environment. Method We model the driver’s decision to deploy visual attention as a stochastic sequential decision-making problem and propose hierarchical reinforcement learning as a computationally tractable solution to it. The…

Diffusion of Drone Journalism: the Case of Finland, 2011-2020

2020

This article details Finnish news organizations’ adoption of drones for journalistic purposes from 2011 to 2020. The theoretical starting point of the article is Rogers’ (1962) diffusion of innovations theory, which explains how new ideas and technologies spread in societies. The main empirical data for the study were derived from a phone survey conducted among the 80 most popular newspapers in Finland. The findings reveal that drone journalism in Finland has already diffused from a few pioneering organizations to a large number of newsrooms, including regional, mid-sized newspapers. Most of the newspapers are either using in-house drones, buying commissioned images, or using both strategie…

Palvelukeskeisen arkkitehtuurin suunnittelumenetelmät

2009

  Alamaa, Jari Markus Palvelukeskeisen arkkitehtuurin suunnittelumenetelmät / Jari Alamaa Jyväskylä: Jyväskylän yliopisto, 2008, 42 s. Kandidaatintutkielma Nykypäivän nopeasti muuttuva liiketoiminnan tehtäväkenttä asettaa tietojärjestelmät uudenlaisien haasteiden eteen. Tietojärjestelmien vaatimustaso on noussut, ja järjestelmän joustavuudesta sekä tehokkuudesta on tullut merkittävä kilpailutekijä. Tilanteen ratkaisemiseksi on oman vastauksensa antanut palvelukeskeinen arkkitehtuuri, joka on teknologiariippumaton ajatusmalli arkkitehtuurin toteuttamiseen. Palvelukeskeinen arkkitehtuuri mahdollistaa tietojärjestelmän toimintojen ja vanhojen perinnejärjestelmien uudelleenkäytön sekä tietojärj…
