Iceland straddles the Mid-Atlantic Ridge and overlies a mantle hotspot. This tectonic setting produces voluminous tholeiitic magmas. Volcanism in Iceland is focussed along three neovolcanic spreading ridges. During the Holocene, the Eastern Volcanic Zone (EVZ) in southeast Iceland has been the most volcanically active and has been the site of several large (>6 km3) eruptions, including the only floodbasalt type eruption in recorded history, the 1783-84 Laki eruption. Three eruptions of large volume have been sampled for this study: the 1783-84 Laki eruption (15.1 km3); the 3,000-4,000 yBP Thjórsárdalur eruption (probably >4 km3); and the ~8,600 yBP Thjórsá eruption (>21 km3). The products of these eruptions have been analysed using a range of analytical techniques, with the specific aim of investigating crystallisation, degassing and mixing processes in the magma reservoirs that feed large eruptions. The Laki eruption has been the particular focus of this study. Samples from different parts of the lava flow show fine-scale variations in trace element concentrations and ratios. This compositional variation is not fully explained by fractional crystallisation processes, but is strongly controlled by crystal accumulation as whole-rock incompatible trace element concentrations show a linear, negative correlation with the mass fraction of crystals in the sample. Simple crystal accumulation models, however, fail to explain the compositional variation, and one explanation is that the homogeneous Laki melt mixed with varying proportions of a crystal mush that contained its own liquid. The results of thermobarometry calculations indicate that the erupted Laki liquid was in equilibrium with olivine, plagioclase and augite at 1-3 kb. Most of the crystals carried by the flow are too primitive to have crystallised from the erupted liquid and barometry calculations indicate that clinopyroxene crystallised at 3-7 kb. The majority of the large crystals hosted in the Laki basalt samples are therefore antecrysts that grew within the same magma plumbing system as the Laki carrier melt but are not in direct chemical equilibrium with it. This finding is verified by the fact that olivine crystals that are too magnesian to be in chemical equilibrium with the Laki whole-rock composition contain melt inclusions with average La/Yb values that are the same within error as the whole-rock values. The wide range of La/Yb values in melt inclusions hosted in the most magnesian (Fo86) olivine crystals in comparison to the least magnesian (Fo<74) indicates the initial variability of the Laki magma prior to concurrent crystallisation and extensive mixing, which acted to homogenise the carrier melt composition. The preservation of a wide range of La/Yb within the melt inclusions in comparison to the whole-rock composition, and a range of La/Yb values in different inclusions from the same crystal, indicates short timescales between melt inclusion entrapment and quenching during eruption. Melt inclusion studies also reveal the dissolved volatile content of the Laki magma at the onset of olivine crystallisation, although the majority of H2O concentrations have almost certainly been reset by low pressure diffusive exchange with the host crystal or surrounding magma. Comparison of the behaviour of volatiles with that of incompatible elements in the melt inclusions indicates that CO2 was degassing during olivine crystallisation, but S, F and Cl were not. New estimates of total volatile loading to the atmosphere during the eruption based on melt inclusion volatile concentrations show SO2 and HCl loading comparable to previous estimates, but higher HF loading. Mass balance calculations show that the observed H2O and CO2 concentrations of melt inclusions hosted in olivines in chemical equilibrium with the Laki whole-rock composition are ~50% and ~93% lower respectively than would be expected if no pre-eruptive degassing of the magma reservoir had occurred, meaning that pre-eruptive degassing of H2O and CO2 from the magma must have been significant. Lava flows from Thjórsá are more compositionally variable than those from Laki, and have different average major and trace element compositions. Compositional variation within the Thjórsá whole-rock composition is explained by a combination of source variation and fractional crystallisation, and, unlike Laki, is not strongly controlled by crystal accumulation.

This thesis mainly examines inflectional morphology of verbal paradigms in Laki, which is considered as one of the Southern varieties of Kurdish language. The association of form and content of morphological markings are viewed from a realizational angle, in which exponents (morphological forms) are associated with the morphosyntactic properties via the application of rules of exponence, appealed by paradigm functions (Stump 2001) and ordered into rule blocks (Anderson 1992). In particular, I applied the paradigm linkage theory proposed and fully developed by Stump (2002 and 2016) to account for Laki verbal paradigms. In this study, it is claimed that alignment pattern and the syntagmatic combination of some of the inflectional exponents such as agreement markers are sensitive to preterite property. Hence, I argue in favor of considering two distinct morphotactic patternings in Laki. As the result of this assumption, depending on whether the inflectional markers attach to a preterite or a non-preterite stem, we should define two separate sets of affix position in this language. Moreover, I examine Laki polyfunctional agreement markers through the consideration of the morphotactics of this language. Applying Stump's analysis (to appear) of Swahili verbal concords, I consider two distinct types of content for these agreement markers: intrinsic content, and positional content. Their positional content is what the morphotactics of the language determines.

In the year 1783 a fissure eruption from Laki in the southern part of Iceland produced a large amount of volcanic gases during a period of eight months. The volcanic gases and aerosols spread across the northern hem sphere due to ideal weather conditions and had a substantial impact on the environment, human health and also climate effects. This, so called dry fog, caused severe health problems, which led to death casualties, killing animals, crops and other vegetation. The consequence was a widespread famine which was aggravated by a hard and long winter in 1783/84. Analysis shows that the Icelandic volcanoes are the primary risk to produce dry fog that can affect Sweden. The fog will most likely cause severe health effects, such as respiratory and cardiovascular problems. It will also cause damage to the vegetation, especially coniferous trees, and it may affect the water by acid chock. The fog may have great impact on the critical infrastructure in Sweden, depending on magnitude and duration. These types of volcanic hazards are difficult to predict and evaluate due to their sporadic nature and the sparse amount of data that is available. It is therefore important to focus on the consequences and develop the Swedish community preparedness on a general basis to handle this type of event.

Abstract Major water soluble ions (Cl-, NO3-, SO42-, CH3SO3-, Na+, K+, NH4+, Mg2+, Ca2+) were determined and the results interpreted from a 121 m long ice core drilled at the summit of the Lomonosovfonna dome, Svalbard. The core covers about the past 800 years. The reliability of anion chemistry for paleoenvironmental studies, and various insoluble particles were also investigated. The ice core studied in this Thesis is the first relatively deep ice core from the central Svalbard that has been analyzed and the results interpreted and published at high resolution for all major ions. One of the clearest features of the ion profiles is anthropogenic impact. SO42- and NO3- concentrations show significant increases by the mid-20th century with slight increases already at the end of the 19th century. In addition excess Cl- and NH4+ from anthropogenic sources are detected arriving after the mid-20th century. Anthropogenically derived SO42- and NO3- have different sources on Lomonosovfonna. NO3- is correlated with NH4+ and requires interpretation in terms of both natural and anthropogenic NH4NO3 sources. The ice core ionic load consists mostly of sea salt ions (Na+, Cl-, K+ and Mg2+). Water soluble Ca2+ are mostly terrestrial in origin. Ion balance together with the Na+/Cl- ratio shows considerable change about 1730 that is most probably due to Na2CO3 input to the ice cap before 1730. Marine biogenic CH3SO3- concentrations are high and stable during the Little Ice Age. CH3SO3- concentrations show a clear change in concentrations in 1920, that is the end of the Little Ice Age in Svalbard. Regardless of anthropogenic impact, marine biogenic SO42- is appreciable in total SO42- budget even in the 20th century. The Laki volcanic eruption in Iceland in 1783 is identified in the ice core as a volcanic tephra layer and high SO42- concentration and acidity peaks. These show that SO42- arrived to the Lomonosovfonna ice cap 6–12 months later than insoluble tephra and the SO42- aerosol caused a drop in temperature. The reliability of ice core ion chemistry analyses was estimated – for the first time in an ice core using two different analytical procedures on 500 adjacent samples from the same depth. Small-scale inhomogeneity in ion concentrations shows that information from ice core layers is representative of the regional environmental and suitable for paleoclimate studies.

Most western Iranian languages, despite their broad differences, show a common quality when it comes to the verbal agreement of past transitive verbs. Dabir-moghaddam (2013) and Haig (2008) discuss it as a grammaticalized split-agreement to encode S, A, and P, which is sensitive to tense and transitivity, and uses split-ergative constructions for its past transitive verbs. Laki shows vestiges of the same kind of verb-agreement ergativity (Comrie 1978) by using a mixture of affixes and clitics for subject and object marking. In this thesis, I investigate how the different classes of verbs show agreement using four distinct property classes. Considering the special case of the {3 sg} and using Hopper and Traugott's pattern for the cline of grammaticality (2003), I argue that although Laki has already lost the main part of its ergative constructions, the case of the {3 sg} marking is yet another sign that this language is in the process of absolute de-ergativization and its hybrid alignment system is moving toward morphosyntactic unity. As a formal representation of the Laki data, the final part of the thesis provides a morphosyntactic HPSG analysis of the agreement patterns in Laki, using the grammar of cliticized verb-forms (Miller and Sag 1997).

Abstract The purpose of this research is to examine the history of elementary schools held by the Church as well as the history of primary schools, comprehensive schools and secondary schools in various municipalities in Lapland up to the end of school year 1998-99. This is a basic research. The examination proceeds from the founding of the first educational institution of each school type. The first itinerant catechists of Finland began teaching in Utsjoki in 1751. The first primary school was founded in Rovaniemi in 1870. Lapland changed over to comprehensive school system in 1972. The Tornio Pedagogium was granted founding permit in 1630. The schools held by the Church were either permanent or itinerant. The importance of permanent schools was insignificant in Lapland. Itinerant school system consisted of two categories; catechist schools and itinerant schools. Their educational aims were uniform. Catechists received their salary from the state whereas itinerant schools were maintained mainly by parishes. Catechist schools were founded only in the parishes of Northern and Eastern Lapland. In other parishes instruction was given by itinerant schools. Even in the beginning of the 1920's the amount of school-aged children in Lapland was higher in itinerant schools than in primary ones. The last catechist school was closed in Inari in 1954. The history of the primary school and comprehensive school can be divided into four periods. The starting point was the year 1866 when the Regulation on Primary Schools was issued. This first period came to an end in 1898 when each municipality of Lapland became obliged to divide its area into school districts. The Regulation on Primary Schools didn't oblige rural municipalities to found schools but made it possible for them. In school year 1897-98 only 24 schools gave instruction in Lapland. The obligation to form school districts brought schools even to the biggest villages in peripheral areas. In school year 1920-21 there were 96 schools in Lapland. The Compulsory Education Act was issued in 1921. The inhabitants of Lapland were active and hence in the autumn 1929 there were already 205 primary schools. The years subsequent to the war meant rapid progress in society with the result that more than 160 new primary schools were founded in Lapland. In school year 1957-58 the amount of schools was at its highest, 425. The fourth period in the history of the primary school and comprehensive school comprises the school years 1958-99. At that time the Primary Schools Act and Comprehensive Schools Act were in force. In the 1960's Finland and first of all Lapland were met by a severe crisis. Until now the increase of population had been strong. Now, however, it began to decrease. The inhabitants of peripheral areas began migrating to towns, Southern Finland and Sweden. In 1974-75 the amount of lower levels of the comprehensive school was no more than 313. The situation improved to some extent for 15 years due to the measures taken by the state. Consequently, in 1989-90 there were still 281 schools. In the 1990's Finland was shaken up by depression. In Lapland, then, unemployment increased, which resulted in migration. In autumn 1998 there were 200 lower levels of the comprehensive school. The only secondary school in Lapland was for a long time in Tornio. The next secondary school was founded in the town of Kemi in 1897. In autumn 1939 there were three educational institutions in Lapland enabling the students to continue their studies at university. After the war, especially in the 1960's, plenty of secondary schools were founded in Lapland. / Tiivistelmä Tavoitteenani on selvittää Lapin kirkollisten alkuopetuskoulujen sekä kansa-, perus- ja oppikoulujen historiaa kuntakohtaisesti lukuvuoden 1998-99 loppuun saakka.

Lukuvuonna 1957-58 kouluja oli ennätysmäärä 425. Neljäs tarkastelukausi käsittää lukuvuodet 1958-99, jolloin kansa- ja peruskoululait olivat voimassa. Suomea ja ennenkaikkea Lappia kohtasi 1960-luvulla suuri murros. Väestön voimakas kasvu pysähtyi kääntyen laskuun. Muuttoliike suuntautui maatalouskylistä kaupunkeihin, Etelä-Suomeen ja Ruotsiin. Ala-asteita oli 1974-75 enää 313. Valtion toimenpitein tilanne tasoittui 15 vuodeksi, ja kouluja oli 1989-90 vielä 281. Lama ravisteli 1990-luvulla Suomea. Lapissakin työttömyys kasvoi aiheuttaen poismuuttoaallon. Syksyllä 1998 ala-asteita oli 200. Torniossa oli pitkään Lapin ainoa oppikoulu. Kemistä tuli oppikoulukaupunki 1897.
