Longitudinal and cross-sectional associations of adherence to 24-hour movement guidelines with cardiometabolic risk
2022
This study aimed to examine 1) adherence to 24-hour movement guidelines over a 2-year follow-up in children aged 6-8 years and 2) association of this adherence with cardiometabolic risk factors. Physical activity and sleep were assessed by a monitor combining heart rate and accelerometry measurements. Screen time was reported by the parents. Body fat percentage, waist circumference, blood glucose, serum insulin, plasma lipids and blood pressure were assessed, and a cardiometabolic risk score was calculated using z-scores. Children were classified as meeting the guidelines if they had on average ≥60min/day of moderate-to-vigorous physical activity during the valid days; ≤120min/day of screen…
Drivers’ experiences during floods: Investigating the psychological influences underpinning decisions to avoid driving through floodwater
2018
Abstract A major risk factor for many flood-related drownings is driving through floodwater. We aimed to understand Australian drivers’ experiences and beliefs with respect to avoid driving through floodwater using the theory of planned behaviour as a framework. Study 1 (N = 23) used a qualitative design to gain an in-depth understanding of individuals’ experiences with driving through floodwater. Study 2 (N = 157) used a survey-based design to identify the factors related to this behaviour including knowledge, beliefs, and social-cognitive factors. In Study 1, drivers identified a range of advantages (e.g., didn’t damage car), disadvantages (e.g., inconvenient, but not so terrible), barrie…
Intravenous iron therapy in patients with heart failure. A double-edged sword
2013
We read with interest the article of Beck-da-Silva et al., who recently concluded that intravenous (IV) iron seems to be superior over oral supplementation for improving functional capacity of heart failure patients [1]. Irrespective of the study design, involving comparison of functional outcomes between two different means of iron supplementation, we raise some clinical issues about the rationale underlying this investigation. According to the data published by Beck-da-Silva et al., the modest number of patients (n = 23) enrolled in this multicenter investigation had moderate anemia (i.e., hemoglobin concentration comprised between 90 and 120 g/L) but no evidence of iron deficiency, which…
Thin film conductivity measurements of carbon nanotube hemicellulose complex
2014
Työssä mitattiin hiilinanoputkista ja hemiselluloosasta koostuvan läpinäkyvän ohutkalvon sähkönjohtavuutta. Materiaali on Nemcel Oy:n kehittämä. Valmistimme useita näytteitä erilaisia mittauksia varten ja testataksemme eri valmistusmenetelmiä. Valmistetun ohutkalvon merkittävimmät ominaisuudet ovat läpinäkyvyys ja hyvä sähkönjohtavuus. Valmistetut kalvot olivat pääasiassa läpinäkyviä, mikä edellytti kalvon ohuutta. Itse materiaali toimitettiin vesiliuoksena, jossa oli 1:1 hiilinanoputkia ja hemiselluloosaa. Kalvot valmistettiin joko spinnaamalla tai kuivattamalla yksittäisiä pisaroita pinnalle. Näytteet valmistettiin pintaoksidioidulle piille, johon oli tehty kultaelektrodit. Kalvoa kuvatti…
Demystifying the Influential IS Legends of Positivism
2018
Positivism has been used to establish a standard that Information Systems (IS) research must meet to be scientific. According to such positivistic beliefs in IS, scientific research should: 1) be generalizable, 2) focus on stable independent variables, 3) have certain ontological assumptions, and 4) use statistical or quantitative methods rather than qualitative methods. We argue that logical positivist philosophers required none of these. On the contrary, logical positivist philosophers regarded philosophizing in general and ontological considerations in particular as nonsense. Moreover, the positivists’ preferred empirical research method was not a survey, but rather a qualitative observa…
Demystifying the Influential IS Legends of Positivism : Response to Lee’s Commentary
2020
We respond to Lee’s (forthcoming) commentary on our article “Demystifying the Influential IS Legends of Positivism” (Siponen & Tsohou [S&T], 2018). Lee offers four arguments against our analyses and conclusions in S&T (2018). First, because logical positivism (LP) has been discredited, he contends it cannot be used as a normative standard in IS. We clarify that our conclusions in S&T (2018) point to (1) the lack of justification for certain IS beliefs, and (2) a misunderstanding rather than legitimacy of LP as a philosophy of science. Second, Lee argues that IS researchers characterizing positivism never said they were following the tenets of LP. We provide evidence to show some influential…
Co-culture of rat brain cells as a tool for studying cell-cell interactions
2012
Brain capillary endothelial cells (BCECs) form the blood-brain barrier (BBB) in response to interaction with other brain cells (astrocytes, pericytes and neurons). BCECs are characterized by tight junctions (TJ), maturation and stabilization of which require different proteins, such as occludin. When co-cultured with astrocytes and neurons, BCECs were found to form a monolayer resembling the natural BBB: paracellular flux of dopamine and sucrose (i.e. compounds which are unable to cross the BBB in vivo) significantly decreased (1), while the transendothelial electrical resistance (TEER) increased. In these conditions, BCECs produced a larger amount of occludin and tended to localize it at t…
Are We Really Hearing in Our Heads What We Think We’re Hearing? The Role of Audiation in Musical Improvisation
2016
An important and valued part of the skill of musical improvisation is to be able to play what we hear in our head (audiation). Improvisation is a cognitively demanding activity, involving the production of musical material in real time. This requires the simultaneous involvement and coordination of many different skills, and places demands on working memory, memory retrieval, auditory and sensory-motor systems. Some recent studies support a cognitive model of improvisation which posits the deployment of stored rhythmic and melodic patterns via motor programmes. According to the theory of event coding, actions and their perceptual consequences share the same cognitive representation and beha…
Impacto del quimerismo hematopoyético precoz en el injerto tras trasplante alogénico de progenitores de sangre de cordón umbilical de donante no empa…
2013
El trasplante de sangre de cordón umbilical (TSCU) ha experimentado un auge muy importante en los últimos años como alternativa a la médula ósea y sangre periférica, debido a la dificultad de encontrar donantes altruistas de estas fuentes de progenitores hematopoyéticos. Los datos clínicos disponibles hasta la fecha muestran una supervivencia libre de enfermedad similar a la observada con el trasplante de médula ósea (TMO) o sangre periférica (TSP). Sin embargo, como consecuencia de la baja dosis celular contenida en la SCU, la tasa de fallo de injertos es más elevada y el tiempo hasta la recuperación de la neutropenia más prolongado. Gran parte de la investigación en el terreno del TSCU se…
Stationary, Second Use Battery Energy Storage Systems and Their Applications: A Research Review
2021
The global demand for electricity is rising due to the increased electrification of multiple sectors of economic activity and an increased focus on sustainable consumption. Simultaneously, the share of cleaner electricity generated by transient, renewable sources such as wind and solar energy is increasing. This has made additional buffer capacities for electrical grids necessary. Battery energy storage systems have been investigated as storage solutions due to their responsiveness, efficiency, and scalability. Storage systems based on the second use of discarded electric vehicle batteries have been identified as cost-efficient and sustainable alternatives to first use battery storage syste…
