Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This study was about students and their study achievements. Data from available records for students admitted to the study programme of business administration was used. The students (N19393) were born in the period 1972–1984, living in Sweden and registered on the study programme sometime between 1993 and 2000. The students were divided into three groups on the basis of the grounds on which the students had been admitted. The first group had been admitted on the basis of their credits from uppersecondary school, the second on the basis of their SweSAT-scores and the third group on the basis of their SweSAT-scores with additional credit for work experience. Study achievement was defined as the number of credits the students managed to attain each semester. The purpose of the study was to see if there were any differences in academic achievement between the three groups. Attention was also given to social background and sex. The results showed that approximately 50% of the students were women. The proportion of students from Social Group 1 was highest among those who had been admitted on the basis of their SweSAT-scores. The most common upper-secondary school programme, for the students who had completed upper-secondary school 1997 or later, was the Programme for Social Science (Samhällsvetenskaplig utbildning). About one fifth of the students who had completed upper secondary school 1997-1999 had taken supplementary secondary-education-level courses after they had left upper-secondary school. The study showed that the female students attained more course points per semester than the male students. There were also differences, in terms of the number of credits attained per term, between the students from the three groups and between students with different social backgrounds. However, these differences were not as extensive as the differences between male and female study achievements.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Students and their study achievements are in focus in this report. Attention is given to the three and a half year long Programme for Social Work. The students (N2956) where divided into three groups, according to the grounds on which they had been admitted to the programme. The first group had been admitted on the basis of their credits from upper-secondary school, the second on the basis of their SweSAT-scores and the third group on the basis of their SweSAT-scores with additional credit for work experience. The purpose of the study was to see if there were any differences in academic achievement between the three groups. Academic achievement was defined as the number of credits achieved at university. Attention was also given to social backgrounds and male/female variance. The results showed that approximately 85% of the students were women. The proportion of students from Social Group 1 was highest among those who had been admitted on the basis of their credits from upper-secondary school. The most common uppersecondary school programme was the Programme for Social Science (Samhällsvetenskaplig utbildning). About one fourth of the students who had completed upper-secondary school 1997-1999 had taken supplementary secondary education level courses after they had left upper-secondary school. The study showed that the female students attained more course points perterm compared to the male students. There were also differences, in terms of the number of credits attained per term, between the students from the three groups and between students with different socio-economic backgrounds. However, these differences were not as extensive as the differences between male and female study achievements.

Mått på studieprestation inom högskolan
- 2004

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This study is about the registration of study achievement (courses, credit points, degrees etc). It analyses the computer based student documentation systems for Swedish colleges and the statutory instruments (Swedish laws and ordinances) that governs these documentations. The National Agency for Higher Education is the central agency responsible for the official statistics about students’ achievements (www.hsv.se). The practical responsibility for coordinating and collecting the data rests with the Statistics Sweden (www.scb.se), a government authority for official statistics. The study shows that the colleges (i.e. at the local level) record study grades (e.g. Fail, Pass or Pass with distinction) but this information is not collected by the Statistics Sweden (on the national level). Attention is also given to the use different types of measurements of study achievement in Swedish research. The study ends with a discussion about future research. One future task is to investigate new ways to use available statistics students’ achievements. A second task is to develop and use new types of measurements of study achievement. Finally, a third task is to increase the accessibility of the official statistics on students’ achievements.

Utbyteskompletteringar bland dem som avslutade gymnasiet 1997-2001 : differenser mellan avgångsbetyg från gymnasiet och betyg som har kompletterats efter den ordinarie gymnasieskolan

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This study is about school grades and college applications. It focuses on the effects of supplementary adult upper-secondary education. From a Swedish perspective, it is important to study the effects of such education due to the important role that grades have in the Swedish college-selection process. The persons in the study graduated from upper secondary school sometime 1997–2001 (N361466). Background variables used in this study are: Age, social group, country of birth, the parents’ country of birth and the parents’ highest level of study. The results indicate that about 50 percent of the persons have studied either the Natural Science Programme or the Social Science Programme in the upper-secondary school. High achievers, in terms of high grades from the last year in upper-secondary school, are those persons born in the country, belonging to social-group 1 and with parents that have a high educational level. The study also shows that the upper-secondary schools have become more generous over time. The grades for the graduating students are getting higher and higher each year. About 30 percent have studied in adult upper-secondary school. About one third of those have boosted their grades. About 40 percent have applied to college. Among the college-applicants, there are more women then men. The college-applicants are also characterised by having parents with a high educational level. About 40 percent of the college applicants have studied in adult upper-secondary school, and that group is characterised by having parents with a low educational level.

Validation of the Swedish university entrance system : selected results from the VALUTA-project 2001-2004
- 2005
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report contains selected results from the Swedish VALUTA-project (2001–2004). The VALUTA-project was a collaborative research effort by researchers from two universities and its aim was to analyse different components of the system for admission to higher education in Sweden. Four of these components were: a) the selection instruments, b) the criteria of study success, c) the relationship between the selection instruments and the criteria of study success, and d) the system of rules and regulations for admission. This report focuses on documents that have published by the VALUTA research group, and the overall aim is to report the major findings from the project. In sum, the VALUTA-project has passed through the stages of progress that were planned. The results from the project together with the development of ideas that took within the project have contributed to the knowledge about the admissions process.

Naturliga bakgrundshalter av bly, zink och arsenik i Svenska ytvatten baserat på metallernas haltvariation i morän och sedimentära jordar : implikationer för EU:s ramdirektiv för vatten och nationella miljömål
- 2007
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Hösten 2006 ska vatten i sjöar och vattendrag kunna bedömas enligt EU:s ramdirektiv för vatten (RDV, 2000/60/EG), vilken successivt håller på att arbetas in i den svenska miljölagstiftningen. Miljöövervakningsprogram skall då vara operationella och utvärderingar av dessa data skall ligga till grund för åtgärdsplaner inom avrinningsområden. Målet är att alla vatten ska uppnå ”God ytvattenstatus” år 2015. För varje typ av sjö eller vattendrag ska typspecifika referensförhållanden fastställas för hydromorfologiska, fysikalisk-kemiska och biologiska parametrar. Dessa skall i huvudsak representera av människan opåverkade förhållanden.Syftet med detta projekt har varit att utveckla modeller för att skatta lokalspecifika referensvärden för Pb-, Zn- och As-halterna i svenska sjöar utgående från de naturgivna förutsättningarna i form av klimat, geologi, vegetation, hydrologi och ytvattenkemi. Modellerna skall kunna användas av miljömyndigheterna vid tillämpningen av EU:s ramdirektiv för vatten och de nationella miljömålen ”Levande sjöar och vattendrag” och ”Giftfri miljö”.Baserat på resultat från riksinventeringen av sjöar år 2000, SGU:s markgeokemiska och biogeokemiska kartering, officiell statistik över klimat, topografi, markslag etc. har statistiska modeller utvecklats för att skatta de naturliga bakgrundshalterna för Pb, Zn och As i skogssjöar vars tillrinningsområden domineras av skog, myr och fjäll. Modellerna baseras på resultaten från 644 sjöar och drygt 28 000 markgeokemiska observationer. Multipla linjära regressionsmodeller användes i samtliga fall. För Pb och Zn utfördes den statistiska inferensen m.h.a. vanlig minstakvadratteknik, men för As användes en robust regressionsteknik som minimerar inflytandet från uteliggare (outliers) bland både beroende och oberoende variabler i modellen. Ingående analyser av de statistiska förutsättningarna har utförts och modellerna uppfyller de teoretiska kriterier som förutsätts av de använda teknikerna. Variationerna i halterna av Pb, Zn och As kan till 71%, 65% respektive 54% förklaras i huvudsak av sjöinterna faktorer med koppling till deras humushalter (TOC) och surhetstillstånd (pH). Dessutom indikerar modellerna att den ackumulerade atmosfäriska depositionen av metaller och sura ämnen inverkar på haltnivåerna.Genom att skapa en andra typ av modeller, där även markgeokemisk och biogeokemisk information tvingats in, ökar förklaringsgraden med 3, 7 och 3 procentenheter för Pb, Zn respektive As. Den marginellt ökande förklaringsgraden av dessa parametrar indikerar att riksinventeringen av sjöar och vattendrag är ett trubbigt underlag för att belysa geokemins betydelse för metallhalterna i ytvatten. Antalet objekt är slumpmässigt utvalda och endast i undantagsfall träffas en sjö med höga metallhalter p.g.a. lokalt förhöjda metallhalter i marken. Humushalt, pH etc. överskuggar markgeokemins inflytande i huvuddelen av objekten eftersom markens metallhalter normalt är tämligen låga.Andra studier visar att det lokalt, i områden med höga metallhalter i marken, föreligger ett samband mellan geokemi och ytvattenhalter av metaller. Det föreligger följaktligen ett fortsatt behov av att studera vid vilka haltnivåer i marken som markgeokemin börjar få betydelse för bakgrundshalterna av metaller i ytvatten. Vi föreslår därför att SGU initierar ett sådant projekt med inriktning mot områden med höga, naturliga metallhalter i marken och där små källvattendrag utgör responssystem.
