Overcoming Barriers to Transnational Organizing Through Identity Work : Finnish-Estonian Trade Union Cooperation
2018
This article analyses a project by Finnish and Estonian unions to adopt ‘organizing model’ strategies through establishing the transnational ‘Baltic Organising Academy’. Initially aimed at Estonian workplaces, successful campaigns inspired Finnish unions to copy the model in Finland. This cooperation was originally motivated by labour market interdependence between the two countries, and the failure of past social-partnership oriented union strategies in Estonia. The willingness of Finnish and Estonian unions to commit resources to transnational cooperation around an ‘organizing model’ marks a dramatic departure from the unions’ previous strategies. This change was accomplished by transnati…

Ilmastonmuutos poliittisena pelinä : poliittinen analyysi vuonna 2007 pidetystä Yhdistyneiden kansakuntien turvallisuusneuvoston ilmastonmuutoskokouk…
2017
Tutkielmassa tarkastellaan Yhdistyneiden kansakuntien turvallisuusneuvostossa 17.4.2007 käytyä ilmastonmuutoskokousta, jossa oli tarkoituksena keskustella ilmastonmuutoksen turvallisuusuhista. Tämän sijaan kokouksessa päädyttiin väittelemään siitä, onko neuvosto sopiva foorumi aiheen käsittelyyn. Siten kokouksessa ilmastonmuutokseen liittyvä keskustelu linkittyi voimakkaasti turvallisuusneuvoston tehtäväkentän kysymyksiin. Tutkielmassa analysoidaan sitä, kuinka kokoukseen osallistuneet valtiot argumentoivat turvallisuusneuvoston sopivuutta käydä keskustelua ilmastonmuutoksesta ja miten ne samalla määrittelivät tilanteen vakavuutta. Aineisto koostuu kokouksen puheenvuoroista ja niihin liitty…
Tapaus Kallasvuon potkut : lehdistö Nokian kolmen toimitusjohtajan imagonrakentajana
2013
Syyskuisena perjantaina vuonna 2010 matkapuhelinyhtiö Nokia ilmoitti, että toimitusjohtaja Olli-Pekka Kallasvuo saa potkut ja hänen tilalleen nimitetään kanadalainen Stephen Elop. Nokian tilanne oli käynyt tukalaksi erityisesti älypuhelinmarkkinoilla, ja Amerikan valloitus näytti epäonnistuneen. Mediassa Kallasvuon lähtölaskenta olikin ollut käynnissä jo kuukausikaupalla. Kun medianäytös Nokian ilmoituksen myötä todella alkoi, katseet porautuivat yhtiön kolmeen toimitusjohtajaan: Nokian huipulle nostaneeseen Jorma Ollilaan, yhtiötä neljä vuotta luotsanneeseen Olli-Pekka Kallasvuohon sekä tulevaisuuden toivoon, Stephen Elopiin. Tässä tutkielmassa selvitetään, millainen imago näille kolmelle …
Protein purification of Agrobacterium tumefaciens phytochrome Agp1 and UV-vis spectroscopy analysis in comparison to DrBphP from Deinococcus Radiodur…
2015
Phytochromes are bimodal light switchable photosensors exist in plants, bacteria and fungi. Incorporating bilin as their chromophore, most bacteriophytochromes (BphPs) function as two-component histidine kinase affected by red/far-red light and regulate downstream physiological activities in the microorganism. The study aims on the purification of Agrobacterium phytochrome Agp1whose phosphorylation activity in its histidine kinase (HK) domain was recently found to be affected by the temperature. The purified proteins Agp1 were assembled with biliverdin IXα (BV) and monitored by UV-vis spectroscopy with BV incorporated DrBphP from Deinococcus radiodurans. Extinction coefficient spectra of “a…
[3+2] Cycloaddition Reaction for the Stereoselective Synthesis of a New Spirooxindole Compound Grafted Imidazo[2,1-b]thiazole Scaffold : Crystal Stru…
2022
A new spirooxindole hybrid engrafted imidazo[2,1-b]thiazole core structure was designed and achieved via [3+2] cycloaddition reaction approach. One multi-component reaction between the ethylene derivative based imidazo[2,1-b]thiazole scaffold with 6-Cl-isatin and the secondary amine under heat conditions afforded the desired compound in a stereoselective manner. The relative absolute configuration was assigned based on single-crystal X-ray diffraction analysis. Hirshfeld calculations for 4 revealed the importance of the H . . . H (36.8%), H . . . C (22.9%), Cl . . . H (10.4%) and S . . . H (6.6%), as well as the O . . . H (4.7%), N . . . H (5.3%), Cl . . . C (1.6%), Cl . . . O (1.0%) and N …
Asymmetric [N–I–N]+halonium complexes in solution?
2020
Assessment of the solution equilibria of [bis(pyridine)iodine(I)]+ complexes by ESI-MS and NMR reveals the preference of iodine(I) to form complexes with a more basic pyridine. Mixtures of symmetric [bis(pyridine)iodine(I)]+ complexes undergo statistical ligand exchange, with a predominant entropic driving force favoring asymmetric systems. The influence of ligand basicity, concentration, temperature, and ligand composition is evaluated. Our findings are expected to facilitate the investigations, and the supramolecular and synthetic applications of halonium ions’ halogen bonds. peerReviewed
Heterogeneous fenton oxidation using magnesium ferrite nanoparticles for ibuprofen removal from wastewater: optimization and kinetics studies
2020
In this study, the catalytic properties of Fenton-like catalyst based on magnesium ferrite nanoparticles for IBP degradation were examined. Structural and morphological studies showed the low crystallinity and mesoporous structure for the catalyst obtained via a glycine-nitrate method. The influences of catalyst dosage, oxidant concentration, and solution pH on the pollutant degradation were investigated. The pseudo-first-order model describes kinetic data, and under optimal condition (catalyst dose of 0.5 g L-1, H2O2 concentration of 20.0 mM, and pH of 8.0), apparent rate constant reached 0.091 min-1. It was shown that Fenton reaction was mainly induced by iron atoms on the catalyst surfac…
Effect of Mg2+ ions on competitive metal ions adsorption/desorption on magnesium ferrite : mechanism, reusability and stability studies
2021
The adsorption behavior of magnesium ferrite in single- and multicomponent metal ions solutions in the presence of Mg2+ ions were studied. A dramatic decrease in the adsorption capacity of magnesium ferrite towards Mn2+, Co2+, and Ni2+ ions for comparison study of single- and multicomponent solutions was established. The affinity of the sorbent in accordance with the maximum sorption capacities increases in the following order Cu2+ > Co2+ > Ni2+ > Mn2+. High efficiency of magnesium ferrite regeneration (~100%) with aqueous solutions of magnesium chloride in the concentration range of 0.001-0.1 M was shown. The low degree of toxic metal ions desorption combined with XRD, IR spectroscopy, and…
