Quantifying and addressing the prevalence and bias of study designs in the environmental and social sciences
2020
Building trust in science and evidence-based decision-making depends heavily on the credibility of studies and their findings. Researchers employ many different study designs that vary in their risk of bias to evaluate the true effect of interventions or impacts. Here, we empirically quantify, on a large scale, the prevalence of different study designs and the magnitude of bias in their estimates. Randomised designs and controlled observational designs with pre-intervention sampling were used by just 23% of intervention studies in biodiversity conservation, and 36% of intervention studies in social science. We demonstrate, through pairwise within-study comparisons across 49 environmental da…
Hidden Pursuits: Evaluating Gaze-selection via Pursuits when the Stimuli's Trajectory is Partially Hidden
2018
The idea behind gaze interaction using Pursuits is to leverage the human's smooth pursuit eye movements performed when following moving targets. However, humans can also anticipate where a moving target would reappear if it temporarily hides from their view. In this work, we investigate how well users can select targets using Pursuits in cases where the target's trajectory is partially invisible (HiddenPursuits): e.g., can users select a moving target that temporarily hides behind another object? Although HiddenPursuits was not studied in the context of interaction before, understanding how well users can perform HiddenPursuits presents numerous opportunities, particularly for small interfa…
Hand-Held texting is less distracting than texting with the phone in a holder: anyway, don't do it
2015
We studied the effects of texting while driving and the effects of mobile phone position (hand-held, holder) on drivers' lane-keeping performance, experienced workload, and in-car glance durations in a motion-platform driving simulator with 24 participants. Overall, we found the known negative effects of texting on lane-keeping performance, workload, and visual attention on road, suggesting that texting on the road in any manner is not risk-free. As a novel finding, we found that hand-held texting led to fewer lane-keeping errors and shorter total glance times off road compared to texting with the phone in a holder. We suggest the explanation is that the drivers had considerably more experi…
Explaining the Difference between Policy-Based Evidence and Evidence-Based Policy: A Nexus Analysis Approach to Mobilities and Migration
2019
Abstract In this policy analysis, we explain the difference between policy-based evidence (PBE) and evidence-based policy (EBP). We argue that better, evidence-based understanding, explanations, and questions can be sought by problematizing the challenging forms of twenty-first century migration and mobilities. We emphasize that this can be done by not confusing PBE with EBP, especially when each is needed as a basis for specific types of action. By focusing on topics often viewed as “unrelated” or confused with one another, we underline the social dynamics that are unfamiliar to many policy actors, professionals, and stakeholders, who rely on scholars for actionable analyses. Our mode of i…
Copenhagen consensus statement 2019: physical activity and ageing
2019
From 19th to 22nd November 2018, 26 researchers representing nine countries and a variety of academic disciplines met in Snekkersten, Denmark, to reach evidence-based consensus about physical activity and older adults. It was recognised that the term ‘older adults’ represents a highly heterogeneous population. It encompasses those that remain highly active and healthy throughout the life-course with a high intrinsic capacity to the very old and frail with low intrinsic capacity. The consensus is drawn from a wide range of research methodologies within epidemiology, medicine, physiology, neuroscience, psychology and sociology, recognising the strength and limitations of each of the methods. …

Riittääkö Ett ögonblick näytöksi merkonomilta edellytetystä kielitaidosta? : kielitaidon arviointi aikuisten näyttötutkinnoissa
2008
Näyttötehtävien sisältö ja vaatimustaso vaihtelevat eri vuosina ja eri tutkintopaikoissa. Tämä selvisi Marita Härmälän tutkimuksessa, jossa hän selvitti aikuisten näyttötutkinnoissa vaadittua kielitaitoa ja sen arviointia. Härmälä analysoi eri aikuiskoulutuskeskusten käyttämiä liiketalouden perustutkinnon näyttötehtäviä ja suoritusten arviointikriteerejä.Tutkimus osoitti, että lähes puolessa näyttötutkinnoista ei tutkinnon suorittajan kielitaidolle asetettu selkeitä vaatimuksia. Kielitaitovaatimuksissa oli suuria alakohtaisia eroja. Tekniikan ja liikenteen aloilla kielitaitoa edellytettiin jonkin verran harvemmin kuin esimerkiksi sosiaali- ja terveys- sekä matkailualalla. Eri tutkintotasois…
Browsing the information highway while driving: three in-vehicle touch screen scrolling methods and driver distraction
2012
Distraction effects of three alternative touch screen scrolling methods for searching music tracks on a mobile device were studied in a driving simulation experiment with 24 participants. Page-bypage scrolling methods with Buttons or Swipe that better facilitate resumption of visual search following interruptions were expected to lead to more consistent in-vehicle glance durations and thus, on less severe distraction effects than Kinetic scrolling. As predicted, Kinetic scrolling induced decreased visual sampling efficiency and increased visual load compared to Swipe, increased experienced workload compared to both Buttons and Swipe, as well as decreased lane keeping accuracy compared to ba…
