Navigating in the Digital Jungle : Articulating Combinatory Affordances of Digital Infrastructures for Collaboration
2019
During digital transformation, companies integrate digital technologies creating large and complex digital infrastructures. These digital infrastructures hold combinatory affordances enabling companies to achieve outcomes that are more than the sum of their parts (i.e., the individual digital technologies). Owing to the complexity of digital infrastructures, these combinatory affordances are ever-present but hidden in the thicket of the infrastructure making their effective use a challenge. We report on an ethnographic study of a large German car manufacturer (Car Inc.) that increasingly integrated digital technologies into its infrastructure as part of its digital transformation strategy. …

Maastohiihto on huomattavan vaativaa kokovartaloliikuntaa niin fysiologian kuin biomekaniikankin kannalta tarkasteltuna. Latujen kunnostuksen, hiihtovälineiden, hiihtotekniikoiden sekä kilpailumuotojen kehityksen myötä hiihdosta on tullut nopeampaa ja vaativampaa, joka asettaa suurempia haasteita voimantuotolle. Vastaavasti hiihtotutkimuksessa huomio on viime vuosikymmeninä siirtynyt enemmän biomekaniikan suuntaan. Ensimmäiset ulkoisten suksi- ja sauvavoimien mittaukset suoritettiin yli kolmekymmentä vuotta sitten ja useita yhteyksiä voimantuoton ominaisuuksien ja hiihtosuorituskyvyn välillä on sittemmin tunnistettu. Edelleen on kuitenkin epäselvää mitkä ovat tärkeimmät voimamuuttujat kuvaa…
Recommendations for design and analysis of health examination surveys under selective non-participation
2019
Background The decreasing participation rates and selective non-participation peril the representativeness of health examination surveys (HESs). Methods Finnish HESs conducted in 1972–2012 are used to demonstrate that survey participation rates can be enhanced with well-planned recruitment procedures and auxiliary information about survey non-participants can be used to reduce selection bias. Results Experiments incorporated to pilot surveys and experience from previously conducted surveys lead to practical improvements. For example, SMS reminders were taken as a routine procedure to the Finnish HESs after testing their effect on a pilot study and finding them as a cost-effective way to inc…
Altered hip control during a standing knee-lift test is associated with increased risk of knee injuries
2020
Few prospective studies have investigated hip and pelvic control as a risk factor for lower extremity (LE) injuries. The purpose of this study was to investigate whether deficits in hip and lumbopelvic control during standing knee lift test are associated with increased risk of acute knee and LE injuries in youth team sports. At baseline, 258 basketball and floorball players (aged 12‒21 y.) participated in a standing knee lift test using 3‐dimensional motion analysis. Two trials per leg were recorded from each participant. Peak sagittal plane pelvic tilt and frontal plane pelvic drop/hike were measured. Both continuous and categorical variables were analysed. New non‐contact LE injuries, an…
Targeted exercise against osteoporosis: A systematic review and meta-analysis for optimising bone strength throughout life
2010
Abstract Background Exercise is widely recommended to reduce osteoporosis, falls and related fragility fractures, but its effect on whole bone strength has remained inconclusive. The primary purpose of this systematic review and meta-analysis was to evaluate the effects of long-term supervised exercise (≥6 months) on estimates of lower-extremity bone strength from childhood to older age. Methods We searched four databases (PubMed, Sport Discus, Physical Education Index, and Embase) up to October 2009 and included 10 randomised controlled trials (RCTs) that assessed the effects of exercise training on whole bone strength. We analysed the results by age groups (childhood, adolescence, and you…
Low back pain during military service predicts low back pain later in life
2016
The aim of the present study was to assess associations between physician diagnosed unspecified low back pain (LBP) during compulsory military service and self-reported LBP and physical fitness measured on average four years after military service. From a total of 1155 persons who had been pass medical examination for military service and who had completed physically demanding military training between 1997 and 2007, 778 men participated in a refresher military training course and physical tests. In this study, the association between LBP during military service and LBP in later life in addition to the association between LBP and physical fitness were examined. A total of 219 out of 778 par…
Interactive Multiobjective Robust Optimization with NIMBUS
2018
In this paper, we introduce the MuRO-NIMBUS method for solving multiobjective optimization problems with uncertain parameters. The concept of set-based minmax robust Pareto optimality is utilized to tackle the uncertainty in the problems. We separate the solution process into two stages: the pre-decision making stage and the decision making stage. We consider the decision maker’s preferences in the nominal case, i.e., with the most typical or undisturbed values of the uncertain parameters. At the same time, the decision maker is informed about the objective function values in the worst case to support her/him to make an informed decision. To help the decision maker to understand the behavio…
