Current agri-environmental policies dismiss varied perceptions and discourses on management of traditional rural biotopes
2017
Traditional rural biotopes (TRBs) are threatened habitats that host significant biodiversity and several ecosystem services, and depend on active management such as low-intensity grazing. The current study explores private landowners’ decision-making on TRB management and abandonment within a social-ecological system framework. We provide insight into supporting resilience of TRB systems in the face of agricultural modernization. Using a mixed methods approach with content analysis and Q analysis, we demonstrate that TRB management fosters cultural, biological, aesthetic, and utilitarian values. These are reflected in different ways through conservationist's, profit-oriented farmer's, lands…
An Ethical Perspective on Loot Box Purchasing : Examining Psychosocial Antecedents and the Association with Indebtedness
2023
Loot boxes are popular random reward mechanisms in digital games, attracting players to invest real money to enhance their gaming experiences. Loot boxes share striking similarities to gambling and might contribute to one’s economic strain, but more research is needed on the underlying vulnerabilities and motivational traits in loot box purchasing. This paper examines associations with self-reported increase in loot box purchasing and debt problems during the first year of the COVID-19 pandemic. International survey data were collected in 2021, consisting of Finnish, Swedish, and British respondents (N = 2,991) aged 18 to 75. Partial least squares modeling was used as an analytical techniqu…

Desarrollo de una estrategía diagnóstica por resonancia magnética multimodal para tumores cerebrales.
2015
RESUMEN Esta Tesis estudia el uso combinado de las imágenes morfológicas obtenidas en los estudios de Resonancia Magnética para el diagnóstico de los tumores cerebrales con las nuevas técnicas que incluyen a la espectroscopía, perfusión y difusión cerebral por resonancia magnética. Estas técnicas tienen valor de biomarcadores, en cuanto son cuantificables, facilitan el diagnóstico precoz del tumor cerebral, su gradación, respuesta y seguimiento tras las medidas terapéuticas empleadas. A este uso combinado lo llamamos Resonancia Multimodal, cuyo fin es incrementar la precisión diagnóstica de los tumores del SNC y su monitorización tras tratamiento. Esta tesis sigue una estrategia diagnóstica…
Lake size and fish diversity determine resource use and trophic position of a top predator in high-latitude lakes
2015
Prey preference of top predators and energy flow across habitat boundaries are of fundamental importance for structure and function of aquatic and terrestrial ecosystems, as they may have strong effects on production, species diversity, and food-web stability. In lakes, littoral and pelagic food-web compartments are typically coupled and controlled by generalist fish top predators. However, the extent and determinants of such coupling remains a topical area of ecological research and is largely unknown in oligotrophic high-latitude lakes. We analyzed food-web structure and resource use by a generalist top predator, the Arctic charr Salvelinus alpinus (L.), in 17 oligotrophic subarctic lakes…
The changing paradigm of document delivery : exploring researchers’ peer to peer practices
2016
Purpose By definition, interlibrary lending is a process involving two libraries. The digital revolution changed the method by which the scientific documents were disseminated during the past couple of decades. Nowadays, researchers can exploit several software applications that enable them to upload, save and deliver their documents from one peer to another without the need for a middle man. This paper reviews this change via a study conducted in two Finnish academic universities. The aim of this study was to determine the extent to which researchers have adopted these new possibilities for document dissemination and how this change will affect the role of the libraries in document delive…
Aerosolization Performance of Jet Nebulizers and Biopharmaceutical Aspects
2019
In this work, 13 jet nebulizers, some of which in different configurations, were investigated in order to identify the biopharmaceutical constraints related to the quality attributes of the medicinal products, which affect their safety, efficiency, compliance, and effectiveness. The aerosolization parameters, including the aerosol output, aerosol output rate, mass median aerodynamic diameter, and fine particle fraction, were determined according to the European Standard EN 13544-1, using sodium fluoride as a reference formulation. A comparison between the aerosol output nebulization time and the fine particle fraction displayed a correlation between the aerosol quality and the nebulization …
Prioritization of Alternatives with AHP Plus Response Latency and Web Surveys
2013
Purpose: Overcome some drawbacks of the widely applied Analytical Hierarchy Process (AHP) related to the use of a rating scale for respondent’s judgments and propose a new method to prioritize alternatives based on web surveys. Methodology/Approach: We use the response latency, i.e. the time taken to make a decision, to replace the rating scale in the pairwise comparisons which is a fundamental part of the AHP procedure. A method combining the AHP with a mathematical model for the response latency is proposed in the paper. Findings: Eliminating the rating scale and leaving only the “take the best” task alleviates the respondent and makes the survey much faster and intuitive. Moreover the re…
El Doppler de la arteria vertebral como alternativa al Doppler de la arteria cerebral media en el diagnóstico de la restricción del crecimiento fetal
2017
En el feto, la irrigación cerebral proviene fundamentalmente de dos ramas, la arteria vertebral y la arteria carótida interna, que formarán posteriormente el polígono de Willis. Por una parte, la arteria vertebral que es, generalmente, la primera rama y la de mayor tamaño de la arteria subclavia. Ésta irriga toda la parte posterior del cerebro. Por otro lado, la arteria carótida interna irriga la parte anterior del cerebro y es de mayor calibre que la arteria carótida externa, ambas procedentes de la arteria carótida común. La arteria carótida interna y su mayor rama, la arteria cerebral media (ACM), ha sido ampliamente estudiada debido a que está implicada en el mecanismo de “brain-sparing…
Claims secured by a registered pledge in sanation proceedings
2019
This study concerns the legal situation of a receivable secured by a registered pledge in a debtor’s sanation (restructuring) proceedings. The registered pledgee has a special position in the course of such proceedings. The study discusses the rules of subjecting the receivable secured by the arrangement, the rules of preparing and contesting the list of receivables, and finally the rules of satisfying the pledgee.
