Regional economic structures in Finland : analyses of location and regional economic impact
2007
This dissertation consists of nine empirical studies which seek to broaden understanding of Finnish regional economic structures. These studies are divided between two topics: 1) regional specialization and industrial concentration in Finland, and 2) regional economic impact analysis. The empirical studies are preceded by an introduction, in which the theoretical background, outline and the main results of the thesis are presented. The research on the first topic is guided by the new economic geography literature, from which answers are sought to the location and agglomeration questions addressed in this dissertation. Evidence is found of increasing post-recession specialization in Finland.…
Aproximación al estudio del desarrollo educativo desde los Ayuntamientos y en el contexto español
2018
The article presents the main results of a study whose purpose has been to investigate the educational development of the municipalities through the actions implemented by the City Councils in the Spanish context. It contains the implementation and validation of a proposed model of stages for educational development, which has resulted in the literature review, 17 in-depth interviews, 2 discussion groups, the pilot implementation of the Model in 3 municipalities, and its validation in practice. Open-ended results indicate some key requirements for educational development: contextualized institutional approaches, flexibility of organizational structures, and a relational system open to innov…
Microwave-Assisted Esterification of Tall Oil Fatty Acids with Methanol Using Lignin-Based Solid Catalyst
2016
During alkaline pulping significant amounts of lignin, carbohydrates (mostly hemicelluloses), and extractives (tall oil soap and turpentine) are removed from wood feedstock. In this study, the catalytic esterification of fatty acids in tall oil with methanol to produce fatty acid methyl esters under microwave irradiation was performed at 100 °C for 10–60 min. A novel heterogeneous acid catalyst tested for this purpose was synthesized from the hardwood alkali lignin that was precipitated by acidification from the black liquor from soda-AQ pulping. The comparative reaction data were obtained by using other solid catalysts, Amberlyst 15, and p-toluenesulfonic acid. The results showed the highe…
Hairy Garlic (Allium subhirsutum) from Sicily (Italy): LC-DAD-MSn Analysis of Secondary Metabolites and In Vitro Biological Properties
2020
Allium subhirsutum, known as hairy garlic, is a bulbous plant widespread in the Mediterranean area and locally used as a food and spice. In the present study, the chemical profile of the ethanolic extracts from bulbs (BE) and aerial parts (APE) were analyzed by HPLC-ESI-MSn, and antioxidant properties were evaluated by DPPH, ABTS and TEAC assays. The traditional use in the diet, and the well documented biological activity of Allium species suggest a potential as a new nutraceutical. For this reason, the potential usefulness of this food can be considered in the treatment and prevention of degenerative Alzheimer disease. For this reason, acetylcholinesterase inhibitory property was investiga…
From language alternation to global multilingual repertoires in Finnish youth radio programs in Finland and Sweden
2014
This PhD study explores multilingualism in Finnish language youth radio broadcasting, with interactional and ethnographic data from Sweden Finnish and Finnish youth radio broadcasting. The interactional data consist of audio recordings from radio programs, while the ethnographic data consist of observations, logbook notes and interviews. The data were recorded and collected during the summer of 2005 from Radio Sweden’s (SR) Finnish language radio station Sisuradio and its youth program Klubi-Klubben, and simultaneously from Finnish YleX, from its X-Ryhmä and YleX Tänään programs. Multilingualism within radio broadcasting is investigated from a qualitative and sociolinguistic viewpoint. The …
Evidence-based programming language design : a philosophical and methodological exploration
2015
Background: Programming language design is not usually informed by empirical studies. In other fields similar problems have inspired an evidence-based paradigm of practice. Such a paradigm is practically inevitable in language design, as well. Aims: The content of evidence-based programming design (EB-PLD) is explored, as is the concept of evidence in general. Additionally, the extent of evidence potentially useful for EB-PLD is mapped, and the appropriateness of Cohen’s kappa for evaluating coder agreement in a secondary study is evaluated. Method: Philosophical analysis and explication are used to clarify the unclear. A systematic mapping study was conducted to map out the existing body of…
El Portfolio Europeo de las Lenguas (PEL): herramienta de evaluación de la composición escrita en español como lengua extranjera
2013
Introducción Esta tesis pretende dar respuesta a uno de los desafíos que enfrentan los profesores de lenguas segundas (L2): mejorar la calidad de la evaluación de la expresión escrita. Partimos de la base del Marco Común Europeo de Referencia para las Lenguas (MCER), publicado por el Consejo de Europa con la intención de orientar la enseñanza y evaluación de lenguas, y del Portfolio Europeo de las Lenguas (PEL), cuyo propósito es aplicar en el aula los principios del MCER. Nos preguntamos si el PEL, que ha sido ampliamente experimentado en Educación Primaria y Secundaria, puede ser también útil como herramienta de evaluación de la composición escrita en niveles universitarios con estudiante…
»just de niillä oli sovmorgon» : Kulturella och pragmatiska aspekter på kodväxling i tvåspråkiga ungdomssamtal i Haparanda, Stockholm och Helsingfors
2017
The aim of the study is to explore situational, cultural and pragmatic factors that might trigger code-switching during informal conversations outside of the classroom at school among bilingual adolescents in Haparanda, Helsinki and Stockholm. An attempt is made to clarify different functions of code-switching, i.e. why bilingual adolescents code-switch from Swedish to Finnish and vice versa. The conversational data, consisting of video-recorded group and pair conversations, was collected in 2014–2015 at six junior high schools in Haparanda, Helsinki and Stockholm. The analysis of the data is qualitative. The theoretical framework is found in the field of translanguaging, which aims to desc…
Optimisation of Conditions for Extraction of Biologically Active Compounds from Common Bryophytes in Latvia / Latvijâ Augoðu Briofîtu Ekstrakcijas Ap…
2015
Abstract Bryophytes are the second largest taxonomic group in the plant kingdom. They contain a high number of biologically active compounds. Studies of their composition are important for understanding evolutionary processes in the plant kingdom. The aim of this study was to assess bryophyte secondary metabolite extraction options and to increase the yields of polyphenols and substances determining the free radical scavenging activity of bryophyte extracts. Similar studies have been conducted using higher plants as model organisms, but not using bryophytes. Comparison of five extraction methods (conventional, Soxhlet extraction, treatment with microwaves, ultrasound, and supercritical CO2 …
