Tämä raportti tarkastelee uutismedian liiketoimintamalleja Pohjoismaissa ja Saksassa kiihtyneen digitalisaation aikakaudella. Toimiala on rakennemuutoksessa, jossa perinteiset tulonlähteet heikkenevät ja uudet digitaaliset mallit ovat vasta osittain korvaamassa niitä. Rakenteellinen murros on pysyvä. Painetun uutismedian levikit ja mainostulot ovat laskeneet kaikissa tarkastelluissa maissa, eivätkä digitaalisen mainonnan ja tilausten kasvu ole vielä kompensoineet menetyksiä täysimääräisesti. Samalla globaaleille alustayhtiöille ohjautuva mainonta heikentää kansallisten uutismediayhtiöiden tulopohjaa. Tässä yhteydessä siirtymä kohti lukijarahoitteisia malleja kiihtyy. Digitaaliset tilausmallit ovat keskeinen kasvusuunta. Norja toimii esimerkkinä onnistuneimmasta digitaalisiin tilauksiin siirtymisen mallista. Saksassakin lukijamaksut muodostavat jo valtaosan uutismedian tuotoista. Markkinat keskittyvät ja kansainvälistyvät. Pohjoismaissa uutismarkkina keskittyy ...

Tutkielmani kertoo Yleisradion Televisioteatterissa esitetyistä kabareeohjelmista vuosina 1966-1970. Aikakauden Yleisradiota kutsutaan myös nimellä Reporadio sen pääjohtajan Eino S. Revon mukaan. Revon voi katsoa tuoneen konservatiiviseen ja maltilliseen Yleisradioon uusia tuulia ja ajatuksia, mikä näkyi myös Timo Bergholmin johtamassa Televisioteatterissa. Helsingin Ylioppilasteatteri oli lähtökohtana kabareiden tekijäkaartille kuvastaen nuorta sukupolvea ideaaleineen. Kabareeohjelmat kuvastivat tekijöidensä arvomaailmaa, jossa näkyivät aikakauden suurten muutosten ja kriisien vaikutukset. Aiheina olivat niin vanhat instituutiot, työläisen asema kuin myös köyhät, sorretut maat ja kansat. Vasemmistolainen ajattelu sai nuorten piirissä kannatusta, jolloin oikeisto koki suurten ikäluokkien levittäytymisen yhteiskuntaan uhkaavana. Televisio toimi olennaisena katsomusten jakajana ja yhteishengen luojana. Televisio oli 1960 luvulla vielä nuori media, joten sen merkit...

This thesis examines private investing in fiction film productions. Finland’s film economy is financed primarily with public funds, yet domestic funding alone is insufficient to cover even the costs of Finnish film production. While larger volumes of capital circulate in the private sector, few filmmakers understand the thinking and decision-making of private investors. The objective of the study is to better understand investors and investment decision-making, film financing and financial instruments, and to build a bridge between financiers and filmmakers. The theoretical framework draws on research on angel investing and delves into the decision-making of angel investors. Through this theoretical lens, the decision-making process of private investors can be examined from a scientific and analytical perspective. The umbrella term “private investor” is used in the analysis. The research question was how private funding can be attracted to film productions. The sub-questions were...

Meteorological data collected in the years 1975 to 1983 at the AAEC's Research Establishment at Lucas Heights, New South Wales, Australia have been summarised. Wind speed, direction and turbulence trace types from 7 and 49 m, temperature difference between 9 and 49 m, ambient temperature and precipitation rates have been extracted as 30 minute averages. Seasonal wind speed and direction roses are summarised for 7 and 49 m together with wind direction persistence statistics which are relevant to short-term (accident) releases of atmospheric pollutants. A 'split-sigma' approach has been adopted for definition of the atmos- pheric stability categories: a 'turbulence method using the wind direction turbulence trace types for the hor- izontal diffusion category; and the US Nuclear Regulatory Commission temperature gradient criteria are combined with Smith's 1972 scheme for the vertical diffusion estimates. Statistics on 10, 50 and 90 per cent probability and average wind speeds and atmosphe...

[ENG] The last decade of the 20th century remains a poorly researched and documented period in the history of Lithuanian electronic music, even though it was during this time that the first independent styles and practices of electronic music began to emerge. Following the restoration of Lithuania’s independence, opportunities to access and adopt Western musical ideas became significantly more open; however, the development of electronic music was accompanied by lack of technology, information, and financial resources, an undefined cultural infrastructure, and a divide between academic and underground scenes. For these reasons, many early electronic music phenomena developed through individual initiatives or outside institutional systems. At that time, several tendencies emerged within the Lithuanian electronic music scene, including electroacoustic, computer-based, synthesizer, dance, industrial, noise, and ambient music. In academic contexts, electronic music was often associated w...

[ENG] The artistic research examines the problem of snow as a disappearing natural phenomenon in the context of climate change in Lithuania. The artist’s goal is to find out whether it is possible to preserve melting snow and/or ice through artistic means, which in the field of research also become a parallel to human temporality. Using her own creative methods - “Snowtint Réservage”, “Hermeneutics of Melting Patterns” and “Snowsofty”, the artist captures melting snow and its traces in her works, showing that applying different strategies reveals the multifaceted nature of the research object. The research combines theoretical and literary sources with the artist’s practical creative activity. Global and local challenges of climate change and the Anthropocene are analyzed, examples of artists working with snow and ice are discussed, and an authorial artistic practice is developed using snow and ice in the creative process, periodically collecting snow samples, preservi...

Sedimentary basins that develop in convergent tectonic settings are excellent archives for evidence of the tectonic processes active during orogen formation. A representative example of this basin type occurs in the Internal Dinarides, at the boundary between the two most distal tectonic units of Adria - the Jadar-Kopaonik and Drina-Ivanjica units. This sedimentary basin possesses unique characteristics not described elsewhere in the Dinarides: it contains an “olistostrome mélange” formation, which Milorad Dimitrijevic (1973) interpreted as a mélange produced by subduction and/or underthrusting of the Drina-Ivanjica element beneath the Jadar block. The type locality where this unit was first described is in the vicinity of town Zvornik, while the tectonic structure along which subduction was postulated was subsequently named the “Zvornik suture”. In this study we focus on another locality where the Upper Cretaceous “olistostrome mélange” has been mapped - the Jelica Mts....

Jihyun Park School of Earth and Environmental Sciences The Graduate School Seoul National University Coastal environments represent dynamic interfaces between terrestrial and marine systems, where dissolved materials are supplied from multiple sources and undergo intensive biogeochemical transformations. These transformations regulate the cycling and fate of dissolved materials, influencing biogeochemical processes in both coastal and adjacent marine environments. However, the sources and behaviors of these materials in coastal environments remain poorly constrained, reflecting the pronounced heterogeneity among coastal systems. Such heterogeneity underscores the importance of resolving material sources and biogeochemical processes within and across diverse coastal systems through integrated, field-based investigations. This study investigates the sources and behaviors of dissolved materials in coastal environments—focusing on dissolved nutrients, dissolved organic matter (DOM), and ...

Single particle inductively coupled plasma mass spectrometry (spICPMS) is a powerful approach for characterizing nanoparticles, microplastics, and even individual cells. In theory, if only one particle is introduced into the plasma at a time, the corresponding signal would show the elemental composition of this particle. However, the sensitivity and detection limits of spICPMS are often constrained by the low transport efficiency (TE) of conventional sample introduction systems. Enhancing TE is critical for maximizing detection capability and minimizing sample consumption, particularly when working with valuable samples like cells. Total-consumption systems achieving 100% TE for spICPMS may be achieved using infrared (IR)-heated spray chambers. In this study, an IR-heated sample introduction system was developed for spICPMS, and multiple optimization strategies were systematically evaluated. The resulting sample introduction system was applied to the analysis of nanoparticles of differ...

We present thermobarometry and geochronology of blocks of epidote and garnet-bearing hornblendites (amphibolite facies rocks with a lack of plagioclase) from mélanges of the Cedros Island subduction complex, Baja California, Mexico, to constrain their age and the thermal gradient of the subduction interface at the time of their metamorphism. The Zr-in-rutile, Fe-Mg garnet-hornblende, and Ti-in-amphibole thermometers yield consistent temperatures ~500-630°C. However, apparent temperatures from Zr-in-titanite thermometry are ≥100°C higher. We hypothesize that during the growth of titanite, the direct replacement of rutile and the limited mobility of Zr4+, Ti4+, and Si4+ to the reaction site of titanite due to a lack of metamorphic fluid during retrogression lead to high Zr concentrations in titanite. Quartz-in-garnet thermobarometry yields a range of pressures ~0.7-1.7 GPa. Whereas previous studies have advocated for taking the maximum of such a pressure range, or statistical evalua...

The global shift toward renewable energy technologies has driven demand for critical and strategic metals (e.g., Cu and Zn). As terrestrial deposits become more expensive and difficult to explore, seafloor massive sulphide (SMS) deposits emerge as promising alternative metal resources. When exposed at the seafloor, sulphides oxidise, forming secondary minerals including Fe-oxyhydroxide (FeOOH) and atacamite, which trap metals otherwise lost to seawater. Despite their potential significance, key unknowns remain regarding their variety, metal content, approximate tonnage, and geochemical evolution at the seafloor, leaving their resource potential and long-term fate uncertain. This study investigates secondary FeOOH deposits at the Semenov hydrothermal field (13°30′N, Mid-Atlantic Ridge) and aims to understand their formation, evolution, and resource potential. Here, I distinguish two types of FeOOH: i) metal-poor (...

Background: Dementia represents one of the most pressing public health challenges of the twenty-first century, with the global burden projected to reach 153 million cases by 2050. Egypt, as the most populous Arab nation, faces a corresponding rise in age-related diseases, yet comprehensive data from low- and middle-income countries remain severely limited. The neuroexposome framework, integrating genetic susceptibility, environmental exposures, and metabolic alterations, offers a powerful strategy to characterize the complex interplay between internal and external risk factors for Alzheimer's disease (AD) and Alzheimer's disease Related Dementias (ADRD). Objectives: This thesis aimed to: (1) examine the distribution of APOE alleles and their interaction with sex in relation to AD risk within the Egyptian population; (2) investigate associations between blood metal concentrations (arsenic, lead, mercury, and lithium) and AD risk and cognitive performance; and (3) characterize the metabo...

While the demand for lithium-ion batteries (LIBs) is increasing, the need for their efficient recycling for recovery of valuable metals is becoming increasingly important. As conventional methods in hydrometallurgy for Li recovery focus on the final stage of the black mass recycling process, Li losses along the process are inevitable. Direct Li extraction from the leachate prior to other elements could be beneficial in terms of high efficiency. Selective separation of Li from multi-component acidic solution encounters challenges because of the co-extraction of other metals. The focus of this thesis is on the suitability of crown ether-based systems for Li extraction from acidic battery metals leachate. In the literature part, hydrometallurgical recovery routes of the waste LIBs and the challenges in the selective extraction of Li are studied with emphasis on crown ether systems. In the experimental part, two crown ethers, benzo-12- crown-4 ether (B12C4) and benzo-15-crown-5 ether (B15C...

Palmetto Ware is a low-fired earthenware that was developed in the Lucayan Islands (The Commonwealth of The Bahamas and Turks & Caicos Islands) ca. AD 700-800. Its production and use by the Lucayans are poorly understood, in part because the raw materials have not been fully characterized. The primary identifying feature is abundant shell temper, lacking Caribbean antecedents. Using mineralogical, elemental, and functional analysis of clay materials and archaeological pottery from across the archipelago, we reconstruct the recipe of Palmetto Ware, highlighting the Lucayans’ strategic use of raw materials in a limited resource environment....

The complex Arabia−Eurasia plate interaction triggered Jurassic−Cretaceous orogenic magmatism within the Sanandaj−Sirjan Zone, the core of the Zagros orogen in Iran. While subduction-related magmatism is expected near convergent margins, the geodynamic mechanisms responsible for Early Cretaceous alkaline magmatism in the Sanandaj−Sirjan Zone remain unresolved. To address this gap, we present new geochronological and geochemical data from a unique suite of lower Cretaceous alkaline magmatic rocks within the composite Cheshmeh−Sefid syenite−gabbroic pluton, located in the southwestern Golpaygan Complex of the central Sanandaj−Sirjan Zone. High-precision zircon U-Pb geochronology using secondary ion mass spectrometry (SIMS) and laser ablation−inductively coupled plasma−mass spectrometry (LA-ICP-MS) reveals emplacement ages of 128 ± 1 Ma for both syenite and gabbro, 127 ± 0.92 Ma for syenite, and 125 ± 0.9 Ma and 125 ± 1.3 Ma for isolated mafic and felsic dikes.

Waste-derived ashes are emerging as promising supplementary cementitious materials, yet their environmental safety is constrained by poorly understood stabilization mechanisms. This study systematically investigates the leaching behaviour and endogenous stabilization capacity of three representative multi-source ashes, including biomass ash (BA), municipal solid waste incineration ash (MA), and volcanic ash (VA), through a long-term rotation-based kinetic leaching approach designed to decouple chemical sequestration from physical encapsulation. Results reveal that leaching behaviour is strongly governed by the chemical environment. Under simulated cementitious conditions, heavy metal concentrations were suppressed by 1-2 orders of magnitude. This immobilization is attributed to a dual mechanism of rapid hydroxide precipitation and progressive structural incorporation into hydration products. The continuous Ca2+ consumption and hydration phase formation confirm that ashes act as reactio...

Background and Aims: Silicon (Si) plays a key role in enhancing stress tolerance in cereals, yet its functional significance in reproductive tissues remains poorly understood. In barley (Hordeum vulgare L.), Si accumulates at high concentrations in seed husks, protecting from excess transpiration and pathogen attack. Here, we investigate the genetic and physiological determinants of Si accumulation in barley seeds and its role in seedling development. Methods: Seed Si concentrations were determined in 251 barley accessions, and a genome-wide association study (GWAS) was performed. Based on the most significant QTL identified, Si accumulation was investigated in the nud1 mutantand its reference Golden Promise. Also, germination and Si uptake assays with whole and dehusked seeds were conducted. Results: Seed Si concentrations varied widely among accessions, primarily determined by the presence of a husk. GWAS identified a major locus on chromosome 7H colocalizing with Nudum1 (Nud1), whic...
