Unlocking mixed oxides with unprecedented stoichiometries from heterometallic metalorganic frameworks for the catalytic hydrogenation of CO 2

2021

[EN] Their complex surface chemistry and high oxygen lattice mobilities place mixed-metal oxides among the most important families of materials. Modulation of stoichiometry in mixed-metal oxides has been shown to be a very powerful tool for tuning optical and catalytic properties. However, accessing different stoichiometries is not always synthetically possible. Here, we show that the thermal decomposition of the recently reported metal-organic framework MUV-101(Fe, Ti) results in the formation of carbon-supported titanomaghemite nanoparticles with an unprecedented Fe/Ti ratio close to 2, not achievable by soft-chemistry routes. The resulting titanomaghemite phase displays outstanding catal…

Implementation of Computer Assisted Experimental Work in Analytical Chemistry Laboratory Teaching

2019

[EN] Computer-Assisted Experimental Work (CAEW) consists in the incorporation of computer-connected apparatus in the laboratory. This is a new insight into teaching of Classical Analytical Chemistry, wherein the experiments are usually manually conducted. However, it does not represent a complete break with traditional methodology, as the design and goal of the experiment are essentially the same. In this work, we present the implementation of CAEW to a practical included in the Laboratory part of “Analytical Chemistry IV”, taught at the fourth academic year of the Degree in Chemistry: “Potentiometric titration of a mixture of iodure and chlorure with silver”. Three couples of students used…

Path-dependencies, constrained transformations and dynamic agency. An accounting case study informed by both ANT and NIS

2013

Purpose – The purpose of this paper is to discuss the compatibility of actor network theory (ANT) and new institutional sociology (NIS) in analysing a case study of accounting change. Design/methodology/approach – This is an interpretive case study. Findings – The Finnish case city experienced several path-dependent changes concerning performance measurement (PM), financial reporting and the adoption of enterprise resource planning system (ERP). New tools such as the ERP have a potential to transform the actors and to change the agency of the actors. Furthermore, the concepts drawing on both ANT and NIS can together enrich analyses of accounting changes. Research limitations/implications – …

Response-To-Intervention in Finland and the United States: Mathematics Learning Support as an Example

2018

Response to Intervention (RTI) was accepted in the early 2000s as a new framework for identifying learning difficulties (LD) in the U.S. In Finland, a similar multi-tiered framework has existed since 2010. In the present study, these frameworks are presented from the viewpoint of the role of assessment and instruction as expressed in documents that describe the frameworks, as it seems that these two components of RTI are the most disparate between the U.S. and Finland. We present a suggestion for the Finnish framework as an example of support in mathematics learning that incorporates principles of RTI (such as systematized assessment and instruction, cyclic support, and modifiable instructi…

The Art-Based Methods in Developing Transversal Competence

2019

This article describes a project called “The art based methods in developing transversal competence” funded by The Finnish National Board of Education. The article is based on the hermeneutic phenomenological approach in action research. The project developed learning environments as well as project-based learning with emphasis on the art-based methods and transversal competence approach to learning. The aim was to develop unique and communal well-being in learning. The project offered tools to strengthen teachers’ professional skills to use expressive, art-based methods in different curriculum-based projects. The professional in-service training project included five contact days in six we…

Trouble in Paradise: a Case of a Technology Industry Supply Network

2009

The development of value networks is regarded as a necessity for achieving agility in global markets. Nowadays the focal companies often state that they are committing to more in-depth partnerships with selected suppliers, which are given more responsibility over both production and R&D. In this article we study the relationship of one focal company with its suppliers and identify the main concerns regarding governance and cooperation within the studied supply network in relation with the focal company’s strategy to enhance its innovative capabilities and ensure capacity in its supplier network. By analyzing the network relationships from three differing vantage points (the focal company, t…

Second language comprehensibility and accentedness across oral proficiency levels : A comparison of two L1s

2021

Second language comprehensibility and accentedness are highly complex phenomena, and numerous studies have been conducted to better understand these constructs. However, research has seldom addressed L2 comprehensibility and accentedness in relation to speakers' proficiency in the target language. This study explores L2 English comprehensibility and accentedness across three proficiency levels. The speakers were 60 teenaged Finns, half of them speaking Finnish as their L1 and half speaking Finland-Swedish as their L1. Using 20-s speech samples, the comprehensibility and accentedness of the speakers were rated by 34 English-speaking teenagers on a 9-point scale. Comparisons were made regardi…

Investigating Syntactic Complexity in EFL Learners' Writing across Common European Framework of Reference Levels A1, A2, and B1

2019

Abstract The study investigates the linguistic basis of Common European Framework of Reference (CEFR) levels in English as a foreign language (EFL) learners’ writing. Specifically, it examines whether CEFR levels can be distinguished with reference to syntactic complexity (SC) and whether the results differ between two groups of EFL learners with different first languages (Sindhi and Finnish). This sheds light on the linguistic comparability of the CEFR levels across L1 groups. Informants were teenagers from Pakistan (N = 868) and Finland (N = 287) who wrote the same argumentative essay that was rated on a CEFR-based scale. The essays were analysed for 28 SC indices with the L2 Syntactic Co…

From interdependence to agency

2011

Maahanmuuttajien määrä Suomessa on kasvanut räjähdysmäisesti sitten 1990-luvun. Muutos väestörakenteessa vaikuttaa myös suomalaisten koulujen arkeen ja opettajien työhön, mutta tutkimusta maahanmuuttajista erityisesti kieliaineiden oppijina on vähän. Tämän tutkimuksen tarkoituksena olikin selvittää millainen maahanmuuttajan kielellinen ympäristö Suomessa on ja erityisesti sitä millainen vaikutus sillä on kielten oppimiseen. Tutkimus tarkastelee maahanmuuttajia toiminnan teorian valossa, ja vastauksia haettiin seuraaviin kysymyksiin: 1) miten maahanmuuttajaoppijat käsitteellistävät itsensä englannin ja suomen kielten oppijina, 2) minkälaisia välittyneisyyden keinoja he käyttävät englannin ja…
