Cancer Prevention with Resistant Starch in Lynch Syndrome Patients in the CAPP2-Randomized Placebo Controlled Trial : Planned 10-Year Follow-up
2022
Abstract The CAPP2 trial investigated the long-term effects of aspirin and resistant starch on cancer incidence in patients with Lynch syndrome (LS). Participants with LS were randomized double-blind to 30 g resistant starch (RS) daily or placebo for up to 4 years. We present long-term cancer outcomes based on the planned 10-year follow-up from recruitment, supplemented by National Cancer Registry data to 20 years in England, Wales, and Finland. Overall, 463 participants received RS and 455 participants received placebo. After up to 20 years follow-up, there was no difference in colorectal cancer incidence (n = 52 diagnosed with colorectal cancer among those randomized to RS against n = 53…
Physical Activity Is Related with Cartilage Quality in Women with Knee Osteoarthritis
2017
Purpose To study the relationship between 12-month leisure-time physical activity (LTPA) level and changes in estimated biochemical composition of tibiofemoral cartilage in postmenopausal women with mild knee osteoarthritis (OA). Methods Originally, 87 volunteer postmenopausal women, age 60 to 68 yr, with mild knee OA (Kellgren Lawrence I/II and knee pain) participated in a randomized controlled, 4-month aquatic training trial (RCT), after which 76 completed the 12-month postintervention follow-up period. Self-reported LTPA was collected along the 12-month period using a diary from which MET task hours per month were calculated. Participants were divided into MET task hour tertiles: 1, lowe…
Professional vision of Grade 1 teachers experiencing different levels of work-related stress
2022
This study explored teachers' professional vision by examining how teachers experiencing low, moderate and high work-related stress reason their eye-tracking recordings in terms of description, explanation and prediction. A qualitative analysis of retrospective think-aloud interviews with 24 Grade 1 teachers showed that teachers predominantly used description in their reasoning, while explanation and prediction were less frequent. The description mainly focused on teacher information/elaboration and classroom management/behaviour. Teachers with moderate stress utilised self-reflection most frequently, whereas teachers with high stress utilised it the least. The results suggest that the leve…
Physical Activity Tracker Application in Promoting Physical Activity Behavior among Older Adults : A 24-month Follow-Up Study
2022
Objectives To investigate whether and how PA tracker application use supports PA behavior among older adults during the first 24 months of use. Methods: The changes in PA levels (i.e., time spent in different PA intensities) and between PA categories (i.e., low, moderate, or high based on total PA) were examined between three different time points: before taking the application into use (t0), after 12 months of use (t1), and after 24 months of use (t2). The data was collected by using the International Physical Activity Questionnaire modified for the elderly (IPAQ-E). Results: A statistically significant increase was observed in walking (χ2 (2) = 29.741, p < .001), moderate PA (χ2 (2) =…
Synchronizing eye tracking and optical motion capture : How to bring them together
2018
Both eye tracking and motion capture technologies are nowadays frequently used in human sciences, although both technologies are usually used separately. However, measuring both eye and body movements simultaneously would offer great potential for investigating cross- modal interaction in human (e.g. music and language-related) behavior. Here we combined an Ergoneers Dikablis head mounted eye tracker with a Qualisys Oqus optical motion cap- ture system. In order to synchronize the recordings of both devices, we developed a gener- alizable solution that does not rely on any (cost-intensive) ready-made / company-provided synchronization solution. At the beginning of each recording, the partic…
Sixth graders’ evaluation strategies when reading Internet search results : an eye-tracking study
2018
Eye-tracking technology was used to examine Internet search result evaluation strategies adopted by sixth-grade students (N = 36) during ten experimental information search tasks. The relevancy of the search result’s title, URL, and snippet components was manipulated and selection of search results as well as looking into probabilities on the search result components was analysed. The results revealed that during first-pass inspection, students read the search engine page by first looking at the title of a search result. If the title was relevant, the probability of looking at the snippet of the search result increased. During second-pass inspection, there was a high probability of students…
Feature selection for distance-based regression: An umbrella review and a one-shot wrapper
2023
Feature selection (FS) may improve the performance, cost-efficiency, and understandability of supervised machine learning models. In this paper, FS for the recently introduced distance-based supervised machine learning model is considered for regression problems. The study is contextualized by first providing an umbrella review (review of reviews) of recent development in the research field. We then propose a saliency-based one-shot wrapper algorithm for FS, which is called MAS-FS. The algorithm is compared with a set of other popular FS algorithms, using a versatile set of simulated and benchmark datasets. Finally, experimental results underline the usefulness of FS for regression, confirm…
Trajectories of reading development: A follow-up from birth to school age of children with and without risk for dyslexia
2006
In order to understand why some children are vulnerable to difficulties in their language development and their acquisition of reading skill, the Jyväskylä Longitudinal Study of Dyslexia followed 200 Finnish children from birth to school age. Half of these children had a family history of reading problems and were considered at risk for dyslexia; the other half were not at risk. A novel analysis, mixture modeling, revealed four subgroups with differential developmental trajectories to early reading. The subgroups who showed either a “dysfluent trajectory” (n = 12; 11 at risk vs. 1 control) or a “declining trajectory” (n = 35; 24 vs. 11) contained more children with familial risk for dyslexi…
Examining the side effects of organizational Internet monitoring on employees
2020
PurposeInternet monitoring in organizations can be used to monitor risks associated with Internet usage and information systems in organizations, such as employees' cyberloafing behavior and information security incidents. Extant research has mainly discussed the effect of Internet monitoring in achieving the targeted goals (e.g. mitigating cyberloafing behavior and information security incidents), but little attention has been paid to the possible side effects of Internet monitoring. Drawing on affective events theory, the authors attempt to reveal that Internet monitoring may cause side effects on employees' Internet usage policy satisfaction, intrinsic work motivation and affective organ…
Heteronormeja vastustavan tyttöyden kompensaatiot Siiri Enorannan Surunhauras, lasinterävä ja Maria Turtschaninoffin Anaché: Myter från akkade -nuort…
2017
Pohjoismaiseen lasten- ja nuortenkirjallisuuteen on rakentunut lähes normatiivinen kuva vallitsevaa sukupuolijärjestystä murtavasta vahvasta tyttöydestä, joka on näkyvissä myös suomalaisessa 2010-luvun nykytyttökirjallisuudessa. Vuosituhannen vaihteen jälkeen kirjallisuuden tyttökuvat ovat kuitenkin moninaistuneet, eikä tyttöhahmojen tarvitse olla enää kaikkivoipaisia. Tyttöyden esitysten moninaistumisen myötä aiemmin liki säännönmukaisesti heteronormatiivisten tyttökirjojen päähen-kilöiksi on noussut myös heteronormeja vastustavia tyttöhahmoja. Artikkelissa tarkastellaan Siiri Enorannan Surunhauras, lasinterävä (2015) ja Maria Turtschaninoffin Anaché: Myter från akkade (2012) –nuortenfanta…
