Using tablets as tools for learner-generated drawings in the context of teaching the kinetic theory of gases

2014

Even though research suggests that the use of drawings could be an important part of learning science, learnergenerated drawings have not received much attention in physics classrooms. This article presents a method for recording students’ drawings and group discussions using tablets. Compared to pen and paper, tablets offer unique benefits, which include the recording of the whole drawing process and of the discussion associated with the drawing. A study, which investigated the use of drawings and the need for guidance among Finnish upper secondary school students, is presented alongside ideas for teachers on how to see drawing in a new light. peerReviewed

Critical factors influencing international sporting success of the Philippines : the athletes' perspective

2017

The aim of this study is to contribute to the understanding of the recent declining performance of the Philippines in international sporting competitions by identifying and evaluating relevant factors that are critical to its international success through the perspective of the national elite athletes. An evaluation of the organizational effectiveness of the national sports governing bodies provides explanation to the poor performance of the country in major international competitions such as the Southeast Asian (SEA)Games. One of the most recent approaches used in measuring organizational effectiveness is the Sport Policy factors Leading to International Sporting Success (SPLISS) model. Th…

A Fatty Acid Based Bayesian Approach for Inferring Diet in Aquatic Consumers

2015

We modified the stable isotope mixing model MixSIR to infer primary producer contributions to consumer diets based on their fatty acid composition. To parameterize the algorithm, we generated a 'consumer-resource library' of FA signatures of Daphnia fed different algal diets, using 34 feeding trials representing diverse phytoplankton lineages. This library corresponds to the resource or producer file in classic Bayesian mixing models such as MixSIR or SIAR. Because this library is based on the FA profiles of zooplankton consuming known diets, and not the FA profiles of algae directly, trophic modification of consumer lipids is directly accounted for. To test the model, we simulated hypothet…

ER-to-Golgi Transport: The COPII-Pathway

2006

The endoplasmic reticulum (ER) is the starting site of the journey of newly synthesized proteinsto the apoplast, plasma membrane and to the vacuolar compartments. Transport between these membranecompartments of the secretory pathway in eukaryotic cells is mediated by vesicles, which are producedby a budding mechanism involving coat proteins that capture specific cargo molecules and helppackage them into coated vesicles. These vesicles are known as COPII-coated vesicles, and are usuallyisolated after their induction in vitro using microsomal membranes, cytosol and a non-hydrolyzableGTP-analogue. COPII-coated vesicles are formed at specific sites in the ER known as ER-exit sites(ERES). ERES a…

Cross-country variation in patience, persistent current account imbalances and the external wealth of nations

2022

This paper is the first to utilize large-scale international surveys on economic preferences to examine the long-run relationships between patience, current accounts and external wealth. We find robust empirical evidence that countries with more patient individuals tend to run persistent current account surpluses, which in turn result in the accumulation of foreign assets. This theoretically plausible but empirically unexplored relationship holds true for euro area current account imbalances, global current account imbalances and net foreign asset positions worldwide. While the existing current account literature concentrates on proximate macroeconomic determinants, this paper’s extension o…

Born entrepreneurs? : Adolescents’ personality characteristics and entrepreneurship in adulthood

2017

Is there an entrepreneurial personality, and does it appear early in life? We provide a new answer to this important question by examining traits related to Type A behavior (Aggression, Leadership, Responsibility, and Eagerness-Energy) measured during adolescence and their relationship to entrepreneurship propensity in adulthood. The results indicate that the early-life Leadership dimension is significantly associated with a higher likelihood of 1) becoming an entrepreneur and 2) being more successful as an entrepreneur, as approximated by sales. peerReviewed

Wastewater constituents impact biofilm microbial community in receiving streams

2022

Microbial life in natural biofilms is dominated by prokaryotes and microscopic eukaryotes living in dense association. In stream ecosystems, microbial biofilms influence primary production, elemental cycles, food web interactions as well as water quality. Understanding how biofilm communities respond to anthropogenic impacts, such as wastewater treatment plant (WWTP) effluent, is important given the key role of biofilms in stream ecosystem function. Here, we implemented 16S and 18S rRNA gene sequencing of stream biofilms upstream (US) and downstream (DS) of WWTP effluents in four Swiss streams to test how bacterial and eukaryotic communities respond to wastewater constituents. Stream biofil…

Simplifying Probabilistic Expressions in Causal Inference

2018

Obtaining a non-parametric expression for an interventional distribution is one of the most fundamental tasks in causal inference. Such an expression can be obtained for an identifiable causal effect by an algorithm or by manual application of do-calculus. Often we are left with a complicated expression which can lead to biased or inefficient estimates when missing data or measurement errors are involved. We present an automatic simplification algorithm that seeks to eliminate symbolically unnecessary variables from these expressions by taking advantage of the structure of the underlying graphical model. Our method is applicable to all causal effect formulas and is readily available in the …

Mikä tekee perheestä perheen? : viidesluokkalaisten käsityksiä perheestä

2017

Tutkielman tarkoituksena on selvittää viidesluokkalaisen käsityksiä perheestä. Käsityksiä pyritään löytämään viidesluokkalaisten tuottamien perhepiirustusten avulla. Piirustusten tueksi tutkielman aineistoa täydentävänä osana toimii viidesluokkalaisen vastaukset kysymykseen: Mikä tekee perheestä perheen? Tutkielmaan osallistui 28 viidennen luokan oppilasta. Aineisto kerättiin erään keskipohjanmaalaisen alakoulun kolmelta eri viidenneltä luokalta keväällä 2017. Oppilaat tuottivat perhepiirustuksen ja vastasivat kysymykseen ”Mikä tekee perheestä perheen?”, kukin ryhmä kolmen eri oppitunnin aikana. Aineisto analysoitiin fenomenografisen analyysin mukaisesti. Fenomenografisen analyysin pohjalta…
