Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Trepartssamtalet, dvs ett samtal mellan kurslärare, student och VFU-handledare, är en central del i den verksamhetsförlagda utbildningen (VFU), och dessutom ett av få tillfällen i hela lärarutbildningen där campus, student och skola möts. Studenterna lyfter fram trepartssamtalet i kursutvärderingar som ett av de viktigaste inslagen under utbildningen. Men trepartssamtalet är också kostsamt på olika sätt. Det kostar i tid att resa ut till skolorna och det behövs också många lärare att bemanna dem. Det är därför viktigt att utveckla och utforska olika former för samtal i VFU som inte är en ren minskning av kvalitet, utan kan vara en form som gynnar studenternas lärande.Projektet omfattar två delstudier där I) studerar digitala trepartssamtal och II) studerar trepartssamtal i grupp. Delprojekt I) är en erfarenhetsbaserad studie där vi jämför våra resultat med till exempel Karlstads universitet som har lärarutbildning (och därmed trepartssamtal) på distans (Johansson och Johansson, 2018). Delprojekt II) innebär trepartssamtal med studentpar, och genomförs som en möjlig aktivitet inom klustren i den nya VFU-organisationen. Studier har visat att studenter som gör VFU i par eller grupp har möjlighet att genom gemensam planering och gemensamma reflektioner hitta kopplingar mellan den egna undervisningen och innehållet i de lästa kurserna (Cavanagh & McMaster, 2015; Manuchechrie, 2002). Delprojekt II sker också i samverkan med VFU-kursansvariga vid institutionerna HSD och ISD.Under paneldiskussionen kommer vi presentera resultaten i de olika delprojekten, vad vi har lärt oss och vilka utmaningar som vi kan ställas inför, till exempel:•Tekniska krav och hantering av GDPR•Krav på stödstrukturer, till exempel digitala verktyg, gott samarbete med VFU-sekretariatet för placeringar och med lärare i övriga kurser•Pedagogiska anpassningar av kursuppgifter och rutiner för samtalet•Studenters och lärares engagemang och medverkan i projektet•Att både få komma tillbaka till engagerade handledare, och att skala upp erfarenheter till att omfatta fler utbildningar

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In 2007 and 2008 a total of 52 coins, t.p.q. 1035, and a silver armring was found at Hellerö, Västra Ed, par., Småland. This is the first Viking-Age hoard to be found in the province for half a century. The hoard is located in a area (Tjust) which is rich in coin finds from the Roman Iron Age until the Middle Ages. The investigation showed that the site had been destroyed when earth was removed and no original context at the site could be observed. The regional context is discussed, and potential port sites can be found in the area. The coins, mainly German (43) and English (5) are listed. In addition a coin struck in 1592 was found.

Holocene relative sea level changes in the Västervik‐Gamlebyviken region on the southeast coast of Sweden, southern Baltic Sea
- 2023

Tidskriftsartikel (refereegranskat)abstract
- We reconstruct the Holocene shore displacement of the Västervik-Gamlebyviken area on the southeast coast of Sweden, characterised by a maritime cultural landscape and archaeological significance since the Mesolithic. Sediment cores were retrieved from four lake basins that have been raised above sea level due to the postglacial land uplift and eustatic sea level changes after the melting of the Fennoscandian Ice Sheet. The cores were radiocarbon dated and analysed for loss on ignition and diatoms. The isolation thresholds of the basins were determined using LiDAR data. The results provide evidence for the initiation of the first Littorina Sea transgression in this area at 8.5 thousand calibrated years before present (cal. ka BP). A relative sea level rise by ∼7 m a.s.l. is recorded between 8.0 and 7.5 cal. ka BP with a highstand at ∼22 m a.s.l. between 7.5 and 6.2 cal. ka BP. These phases coincide with the second and third Littorina Sea transgressions, respectively, in the Blekinge area, southern Sweden and are consistent with the final deglaciation of North America. After 6.2 cal. ka BP, the relative sea level dropped below 22 m a.s.l., and remained at ∼20 m a.s.l. until 4.6 cal. ka BP coinciding with the fourth Littorina Sea transgression in Blekinge. From 4.6 to 4.2 cal. ka BP, the shore displacement shows a regression rate of 10 mm a−1 followed by a slowdown with a mean value of 4.6 mm a−1 until 1.6 cal. ka BP, when the relative sea level dropped below 3.3 m a.s.l. The Middle to Late Holocene highstand and other periods of minor sea level transgressions and/or higher salinity between 6.2 and 1.7 cal. ka BP are attributed to a combination of warmer climate and higher inflow of saline waters in the southern Baltic Sea due to stronger westerlies, caused by variations in the North Atlantic atmospheric patterns.

Stäket vid Valstad : Arkeologisk provundersökning, Kallåker 4:4, Gamleby socken, Västerviks kommun, Kalmar län, Småland
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In spring 2016, Södertörn University and MARIS, in collaboration with Västerviks Museum, conducted an archaeological research survey at Stäket, Kallåker 4:4 in Gamlebysocken, Västervik municipality, Kalmar County, Småland. At the survey two trenches were dug on land in connection with a previously known "pole blockage" in the water of Dynestadviken at a place called Stäket. One trench was placed in a stone construction situated close to the level of the Viking age shore line. The other trench was orientated in today's wetland adjacent to the timber construction in the water.The stone "cairn- like" construction lays in line with the timber construction in the water and are interpreted by us as associated with the underwater remains. The test trench was done in that part of the construction which is closest to the water. But the stone cairn seems to continue west at least 10 m up the beach slope. In the trench a brow, a flint and fragments of processed wood were found. Underneath and between the stones, wooden poles emerged of which one dates back to Viking age-early Middle Ages.The other trench, in the wetland closer to the water, could only be dug to approx. 0.2 m depth, but in this area several wooden poles appeared as well as parts of planks and a smallbox shaped wooden construction.Several of the upright standing poles, both in the water and on land have been dated to late Iron age, but there are also some dating of poles and planks from late Medieval/EarlyModern period. In connection to wood sampling in the water for dating of the poles a well worked oak plank also was found. The plank is dated to late Viking period and is very likely from a boat.During late Viking period, the place for the site was the most topographical strategic part of the waterway between the bay of Gamlebyviken and the protected inner water around Dynestadsjön. The choice of place gives an indication that the construction during this time is linked to strategy and protection of the rich Iron Age homeland north of the construction.The exact function of the constructions at Stäket cannot be said at the present time and there are several possible functions. The most obvious interpretation is to see it as a blockage defending the inlet, but there is also a possibility that the remains we know about today actually are a part of a larger harbour arrangement. Other possibilities which can't be excluded is that the construction could have been used for fishing or that some of the poles are remains of a bridge over the narrow inlet. Combinations of these different functions areof course also possible. Considering the different dating and the mix of wooden material is also very likely that the use and function of the place have changed during history.

The 2018 trench was placed in the upper part of the stone construction, 10 m up the beach slope, close to the test trench dug in 2016. The aim was to collect more data regarding the stone structure, it´s construction and use. Among the findings are flint fragments, horseshoe nails, coins and a clay pipe, all with a span from the 11th century to the 19th century.During late Viking period, the place for the site was the most topographical strategic part of the waterway between the bay of Gamlebyviken and the protected inner water around Dynestadsjön.

Mapping of emissions from reporting point sources and Estimation of emission factors from reporting waste water treatment plants
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- According to EC Regulation 166/2006 the operator is responsible for the quality of the information they report. The competent authority is responsible, however, to assess whether the reported infor-mation is complete, consistent and credible. Sweden has reported data to the E-PRTR (European Pol-lutant Release and Transfer Register) since the year 2007. However, there has been no general survey of the reporting point sources with respect to which substances that are reported by the companies in a particular industry, neither which method that has been used to report the emissions.Earlier work has shown that only a few organic compounds were reported from very few waste water treatment plants (WWTP) in SMP, e.g. DEHP, alkylphenols, nonylphenol and PAHs. Earlier studies had also shown that there seems to be a huge under-reporting of the emissions of organic substances.For alkylphenols and APEs, DEHP, nonylphenol, octylphenol and PAH it is estimated that, the amounts reported for Sweden should increase by 204, 202, 2288, 823 and 300% respectively if all WWTPs reported. It is also difficult to measure substances in the effluent (outgoing water from WWTP) and therefore there is a need to find other ways, such as use of emission factors to estimate releases to water. An aid to calculate the emissions could provide a more complete reporting from WWTP in the future.The project had two sub-projects:The purpose of the first sub-project was to map the data reported for 2011 to the E-PRTR (re-leases to water and air and as off-site transfers to WWTP), for all reported E-PRTR pollutants and all industry sectors in Sweden. With mapping is here meant to sort, organize and group the emissions data and methodology for the development of emission data for facilities in the same industry sectorThe purpose of the second sub-project was to develop emission factors for estimating emis-sions to water from municipal WWTP, for 18 substances / substance groups1. These emission factors could be used by WWTP in the reporting of emissions data in the emission declara-tions in the annual environmental report which in turn are used to the E-PRTR reporting.1 nonylphenol and nonylphenol ethoxylates, octylphenol and octylphenol ethoxylate, polybrominated dinfenylethers(PBDEs) phthalate (DEHP), tetrachlorethylene (per), tetrachloromethane (carbon tetrachloride) Trichlorobenzenes, 1,2-Dichloroethane, Trichloroethylene (tri) dichloromethane, trichloromethane (chloroform), PAH (total 4) anthracene, flouranten, benzo (g, h, i) perylene, chloroalkanes (C10-13), hexachlorobutadiene (HCBD), isodrin.In the first subproject, emission data from the Swedish Portal for Environmental Reporting (SMP) were studied regarding releases year 2011 for receiving media: air, water and off-site transfers of pol-lutants to WWTP from PRTR classified facilities. For the receiving media air, totally 666 facilities reported emissions year 2011. The corresponding numbers for releases to water and as off-site trans-fers to waste water were 331 respectively 157.The mapping of emissions from reporting point sources was performed for each receiving media. Data was compiled for each pollutant and E-PRTR activity. For each E-PRTR activity and pollutant, emis-sion data was presented as a percentage of the total number of PRTR classified facilities reporting emissions to the receiving media. The results were presented as percentage below and above the threshold values to E-PRTR. Further, a compilation of determination methods used for reporting re-lease data to SMP were performed. The methods used were divided into measured (M), calculated (C) 6and estimated (E) and compiled for each receiving media and pollutant. For the organic substances, it was further investigated if the use of release determination methods could be presented per receiving media, pollutant and E-PRTR activity.The result showed that generally, for all the receiving media and pollutants, there was higher percent-age of reported releases below the thresholds values to E-PRTR compared to releases above the thresholds. The results from this project indicated that the thresholds to E-PRTR, in many cases, may be too high. Emissions of all pollutants are not expected to occur from all sectors. There was however some examples of sectors missing expected release data, for instance, releases of CH4 and N2O to air from sector 7 (Intensive livestock production and aquaculture). Out of all the facilities within sector 7 only one reported emissions of N2O below the E-PRTR threshold and none above. None of them re-port any values neither below nor above the E-PRTR threshold for CH4. Organic substances as a group was rarely reported except for release of dioxins and PAH to air, AOX to water and phenols and TOC/CODCr to water and as off-site transfer to waste water. If reported, the emissions generally were below the thresholds to E-PRTR.The use of determination methods (C, M, E) for reporting releases to air, water and as off-site transfer to waste water varied with different pollutants and receiving media. For many of the pollutants, lack of data made it difficult to compare and map the methods to report the releases. Generally, measurement methods were more frequently used and the estimation methods were used less often.In the second subproject two different methods were used to try to develop emission factors; previous measurements and modelling. By using previous measurements of the substances in the effluent from WWTP and in sewage sludge a factor could be estimated. Data were retrieved from a report (Petters-son and Wahlberg, 2010) and from national environmental monitoring. For the modelling, a Sewage Treatment Plant (STP) model that calculates how a substance is distributed between air, water, sewage sludge and biodegradation was used. The model selected for this purpose is called STP-EX and was developed by Seth et al. (2008). The model includes the octanol-water partition coefficient (Kow), which is a measure of how a substance / group of substances are distributed between water and fat. The more hydrophobic the substances are, the more they bind to particles, such as the sewage sludge. The approach is to use the distribution between the different media and the known amount of sewage sludge produced in the WWTP and then estimate the amount (or concentration) of the substance in the effluent.Looking at the entire dataset from previous measurements, 110 of totally 132 reported data on release to water were below the detection limit for the analyses. The corresponding numbers for sludge were 39 of 164. A ratio (total amount of chemical in water/total amount chemical in sludge) was calculated for the substances and WWTPs when both the sludge and effluent water data were available. Due to a large number of values below the detection limit, ratios could only be developed for 4-tert-octylphenol and 4-nonylphenol. The ratios for 4-tert-ocylphenol varied between 0.06 and 0.52 for the different WWTPs, with an average of 0.11. The ratios for 4-nonylphenol, branched varied between 0.02 and 23 with an average value of 4.4.The ratios vary between the different WWTP, which may depend on both the normal variance due to different load, size and technical properties of the WWTPs.The results from the modelling showed that the predicted chemical distribution differs between chemi-cals as well as between the different WWTPs, but the general pattern is that hydrophobic compounds, will mainly end up in the sludge and VOCs will mainly biodegrade or evaporate. Other compounds of intermediate hydrophobicity and reactivity, such as e.g. fluoranthene, will partly biodegrade and partly 7end up in the sludge. Most substances included in the study had a ratio of 0,1 or less which means that only a minor part will end up in the effluent. A ratio above 1 implies that on an annual basis, larger amounts of chemical are predicted to be released with effluent water than with sludge. An emission factor (total amount of chemical in water/total amount chemical in sludge) of about one or above was estimated for tetrachlorethylene, tetrachloromethane, trichlorobenzene, 1,2-dichloroethane, trichloro-ethylene, dichloromethane and trichloromethane. The results showed that the ratios for individual substances differ between the included WWTPs, by up to a factor of 30 (for trichloroethylene. The water/sludge ratio differs not only between chemicals and different WWTPs, but may also vary between years. TSS (Total Suspended Solids) in the effluent water and the volume of incoming water (influences the hydraulic retention time and thus biodegradation) and its properties were parameters that had a high influence on the factor for the included substances. These two factors are prabably also an explanation for the large variations in factors calculated by measurements.Both methods (measurements and modelling) illustrate a large variation between different WWTPs, and an inappropriateness of using one common substance specific ratio for emission calculations. This leads to the recommendation that WWTP specific ratios should be derived that can be used to estimate emissions with outgoing water from sewage sludge data. There are relatively few WWTPs that have to report to E-PRTR and for those WWTP’s modelling is the preferred method, since it proved to be difficult to measure most substances in the low concentration that is needed. It is also important to pay attention to changing conditions between years in the WWTP, as they influence the fate of the chemi-cals. To evaluate the applicability of the suggested model assessment methodology for Swedish WWTPs it is desirable to conduct empirical monitoring studies in selected WWTPs and for selected substances to investigate how well the model agrees with measurements. Even though the model has shown good results compared to measured data in earlier studies, it has not been evaluated for Swed-ish conditions, which in s

Tidskriftsartikel (refereegranskat)abstract
- Reconstructions of past land use and related land-cover changes at local and regional scales are needed to evaluate the potential long-term impacts of land use on the coastal waters of the Baltic Sea. In this purpose, we selected the Gamleby area at the Swedish Baltic Sea coast for a case study. We use a new, high resolution pollen record from a small lake (Lillsjön) located 3.6 km NNW of the bay Gamlebyviken and detailed analysis of the available archeological data to reconstruct local land-use changes over the last 3000 years. To estimate land-cover change at local (2–3 km radius area) and regional (50 km radius area) scales we use four additional, published pollen records from two small and two large lakes (25–70 km S of Lillsjön) and the Landscape Reconstruction Algorithm, a pollen-vegetation modeling scheme. Results show that regional and local (small lakes Lillsjön and Hyttegöl) land-cover changes are comparable over the last 1500 years (Late Iron Age to present), and that landscape openness was much larger locally than regionally (difference of 20–40% cover over the last 500 years). The periods of largest potential impacts on the Gamlebyviken Bay from regional and local land use are 200–950 CE (Late Iron Age) and 1450 CE to present, and of lowest potential impacts 950–1450 CE. The question on whether the large landscape openness 1150–50 BCE and significant afforestation 50 BCE–200 CE reconstructed for Lillsjön’s area are characteristic of the Gamlebyviken region will require additional pollen records in the catchment area.
