Visual understanding of divergence and curl: Visual cues promote better learning

2019

Prior research has shown that students struggle to indicate whether vector field plots have zero or non-zero curl or divergence. In an instruction-based eye-tracking study, we investigated whether visual cues (VC) provided in the vector field plot can foster students’ understanding of these concepts. The VC were only present during instruction and highlighted conceptual information about vector decomposition and partial derivatives. Thirty-two physics majors were assigned to two groups, one was instructed with VC about the problemsolving strategy, and one without. The results show that students in VC-condition performed better, responded with higher confidence, experienced less mental effor…

Agricultural potential of anaerobically digested industrial orange waste with and without aerobic posttreatment

2012

The potential of anaerobically digested orange waste with (AAD) and without (AD) aerobic post-treatment for use in agriculture was evaluated through chemical analyses, short-term phytotoxicity and long-term plant assays. Chemical analyses showed that AD contained ammonia and organic acids, and aerobic post-treatment did not significantly remove these phytotoxins. The N:P2O5:K2O ratio in AD was 1:0.26:0.96 and aerobic post-treatment did not change the composition in AAD except for K2O (1:0.26:1.24). Heavy metal contents in AD and AAD were more or less the same and were below the upper limit recommended for non-sewage sludge application on agricultural soils. Short-term phytotoxicity tests sh…

Adsorption and Activation of Water on Cuboctahedral Rhodium and Platinum Nanoparticles

2017

Rh and Pt are widely used as the components in heterogeneous catalysts for multiple industrial applications. Because the metals are typically in the form of nanoparticles in real catalysts, it is important to carefully select models for the computational prediction of the catalytic properties. Here we report a first-principles study on the water activation, an important step in numerous catalytic reactions, using the finite-size Rh and Pt nanoparticle models and compare them to the extended surface models. We show that regardless of the model, adsorption and activation of water is practically identical for both metals, whereas the dissociation is energetically more favorable on Rh. The expe…

Visualising maritime vessel open data for better situational awareness in ice conditions

2018

Situational awareness of maritime vessels in ice conditions is important for the operation of supply chains. In the artic sea areas, the ice conditions pose a major challenge for maritime vessels getting stuck in the ice and being significantly delayed in arrival to harbor. Data science and open data provide new opportunities to overcome these challenges. This paper introduces available open data sources and data visualizations that can be used to develop applications, for example, for detecting maritime vessel collision, predicting estimated time of arrival to harbor, as well as maritime vessel route optimization in ice conditions. The paper begins by introducing available open data source…

Enterprising Culture : Discourses on Entrepreneurship in Nordic Cultural Policy

2017

ABSTRACTThe sphere of arts and culture has been going through a process of economic reevaluation during the last few decades. Parallel to the rise of a creative economy discourse, which both in its political and scientific forms has highlighted the economic significance of culture and arts, entrepreneurship has become a feature in the cultural policy of many countries. In this article, we compare how entrepreneurship is established and used as a concept in cultural policy discourses in two Nordic countries, Norway and Finland. Through analyzing policy plans and documents, we discuss what is seen as positive cultural or artistic activity in the framework of entrepreneurship, and we identify …

Strategic choices of Finnish universities in the light of general strategy frameworks

2016

This study examines university strategies from the content perspective. Since the early 1980s, the pressure to adopt strategic management in universities and other higher education institutions has increased because of issues including reduced public funding, pressures and possibilities for internationalization, developments in teaching technologies, and demands for increased accountability to stakeholders. The study employs content analysis and multivariate statistical techniques to examine the written strategies of 13 Finnish universities formulated after the University Act 2010 that aimed at enhancing their competitiveness in the global arena. The studied organizations cover practically …

Homing blogs as ambivalent spaces for feminine agency

2017

This article discusses a form of lifestyle blogging where women blog about their homes and everyday lives. In these homing blogs, selfrepresentations are characteristically spatially demarcated within the private sphere of the home. As these repeated representations of women in their homes take place in the public space of the internet, homing blogs work towards naturalizing the home as a women’s sphere. Written and commented on mostly by other women, homing blogs represent a feminine form of self-expression and communication that functions as a discursive expression of ongoing social, economic, and cultural changes in affluent Western societies. In this article, Finnish versions of these h…

Limittäiskielisyys osana kuvataiteen prosesseja

2023

Tässä artikkelissa käsittelen kahdeksan Berliinissä asuneen suomalaislähtöisen kuvataiteilijan käsityksiä kielten merkityksestä identiteettiinsä ja taiteeseensa. Vastaan kolmeen tutkimuskysymykseen; ensinnäkin siihen, miten eri kielten käyttö on vaikuttanut taiteilijoiden identiteettiin, toisekseen siihen, miten he käyttävät kieliä visuaalisessa taiteessaan ja lopuksi siihen, mikä rooli kielellä, monikielisyydellä/limittäiskieleilyllä on heidän taiteessaan. Kesällä 2019 ja talvella 2021 kerätty aineisto koostuu kuvataiteilijoiden haastatteluista, ottamistani valokuvista taiteilijoiden työhuoneilta ja heidän töistään sekä heidän julkaisemistaan kirjoista ja nettisivuista. Tässä artikkelissa …
