Minervan miehet : tieteellisen antikvariaatin kirjanvälitystoimintaa akateemisissa verkostoissa
2020
Tutkin artikkelissani henkilö- ja verkostohistoriallisesta näkökulmasta antikvaarista kirjakauppaa, jota käytiin Helsingin yliopiston opiskelijoiden ja tutkijoiden muodostamissa akateemisissa verkostoissa. Minerva Oy oli 1800- ja 1900-luvun vaihteessa Helsingissä toiminut tieteellinen antikvaarinen kirjakauppa. Tarkastelen Minerva-osakeyhtiön historiaa 1890-luvulta 1910-luvulle sen piirissä toimineiden henkilöiden kautta hyödyntämällä kollektiivibiografista menetelmää. Pohdin, miten ja miksi akateemiset henkilöverkostot edesauttoivat liikkeen kirjanvälitystoimintaa. Minervan perustajat ja keskeiset toimijat tunsivat toisensa opiskeltuaan ja työskenneltyään Helsingin yliopiston piirissä. Näi…
Trobriand-saarilta internetiin : antropologisen kenttätyön haasteita virtuaalisessa ympäristössä
2009
Internet kehitettiin alun perin 1960-luvulla puolustus- ja tiedustelupalvelujen tarpeisiin, mutta 1980-luvulla kehitettyjen visuaalisten käyttöliittymien ansiosta siitä on tullut yhä tärkeämpi osa länsimaisen ihmisen arkipäivää. Vaikutukset sosiaaliseen ja kulttuuriseen kanssakäymiseen ovat olleet mittavia, minkä vuoksi myös sosiaali- ja kulttuuritieteet ovat olleet kiinnostuneita siitä mitä ihmiset tekevät internetissä. Kansainvälisesti virtuaaliantropologista tutkimusta on tehty jo 1990-luvun alusta saakka, mutta Suomessa marginaalisesti vasta 2000-luvulla. Ennakkoluulot virtuaalista kenttätyötä kohtaan saattavat olla tutkimuksen vähäisyyden syynä, minkä vuoksi artikkelissa tuodaan…
Fractional Hardy inequalities and visibility of the boundary
2013
We prove fractional order Hardy inequalities on open sets under a combined fatness and visibility condition on the boundary. We demonstrate by counterexamples that fatness conditions alone are not sufficient for such Hardy inequalities to hold. In addition, we give a short exposition of various fatness conditions related to our main result, and apply fractional Hardy inequalities in connection to the boundedness of extension operators for fractional Sobolev spaces.
Quantification of Platinum in Edible Mushrooms Using Voltammetric Techniques
2021
Edible mushrooms are a food source with interesting nutritional values. The chief objective of this research was to develop a consistent method for the quantitative ultra-trace analysis of Pt in mushrooms, which is complex because it cannot be readily quantified by common analytical procedures. This research is one of the first analytical methods to establish Pt amount in these vegetables. In this research, 28 different edible mushroom samples from Italy were investigated. Determination of Pt in mushrooms was completed using Differential Pulse Voltammetry (DPV). In this study, we applied the standard addition method because there are no certified reference mushrooms containing platinum grou…

Particle balance and return loops for microplastics in a tertiary-level wastewater treatment plant.
2021
Highlights: Dewatering by centrifugation was a step that removed a high number of MPs from the sludge. Sludge retained especially the fibrous microplactics. Reject water transported microplastics inside a wastewater treatment plant. Disc filter-based tertiary treatment ensured removal of 99% of microplastics in wastewater. Microplastics (MPs) from households, stormwater, and various industries are transported to wastewater treatment plants (WWTPs), where a high proportion of them are captured before discharging their residuals to watersheds. Although recent studies have indicated that the removed MPs are mainly retained in wastewater sludge, sludge treatment processes have gained less atten…
A Comparative Eye Tracking Study of Usability—Towards Sustainable Web Design
2021
Websites are one of the most frequently used communication environments, and creating sustainable web designs should be an objective for all companies. Ensuring high usability is proving to be one of the main contributors to sustainable web design, reducing usage time, eliminating frustration and increasing satisfaction and retention. The present paper studies the usability of different website landing pages, seeking to identify the elements, structures and designs that increase usability. The study analyzed the behavior of 22 participants during their interaction with five different landing pages while they performed three tasks on the webpage and freely viewed each page for one minute. Th…
The MIMOSE Approach to Support Sustainable Forest Management Planning at Regional Scale in Mediterranean Contexts
2017
In recent decades, Mediterranean landscapes have been affected by human-induced drivers, such as land use and climate change. Forest ecosystems and landscapes have been particularly affected in mountainous regions due to limited management and stewardship, especially in remote areas. Therefore, there is a need to set up new strategies to enhance ecosystem services in forested areas which, in turn, will benefit local communities and economies. In this study, we implemented a new approach—Multiscale Mapping of Ecosystem Services (MIMOSE)—to assess ecosystem services in Mediterranean forests located in a mountainous region of Italy. We spatially assessed timber provision and carbon sequestrati…
The Relationship between Knowledge Characteristics’ Fit and Job Satisfaction and Job Performance: The Mediating Role of Work Engagement

Knowledge workers are highly valued by organizations, but there is a lack of evidence about the role of work engagement in the satisfaction and performance of these workers. Harmonization and Person&ndash
Inspiriting Innovation: The Effects of Leader-Member Exchange (LMX) on Innovative Behavior as Mediated by Mindfulness and Work Engagement
2021
Continuous innovation has become a key to gaining a sustainable competitive advantage for organizations in the 21st century. By focusing on the underlying mechanisms (i.e., mindfulness and work engagement) by which it works, this study addresses the quality of leader–member relationships and their relevance for innovation in the workplace. Using a sample of 210 employees from 17 Spanish companies, a two-wave longitudinal design evaluated the mediational roles of mindfulness and engagement between leader–member exchange (LMX) quality and innovative work behavior (IWB) in an organizational context. Over the course of a year, two questionnaires were administered to measure LMX quality, mindful…
