”I don’t believe the meaning of life is all that profound” : A study of Icelandic teenagers’ life interpretation and values
- 2008

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- What do teenagers recount about themselves and their interpretation of life and values, and what characterises individual teenagers’ perceptions and statements? What is the relation between teenagers’ life interpretation and values and social circumstances? What challenges to school religious education do the teenagers’ perceptions and statements represent? These questions are central to the study Icelandic Teenagers’ Life Interpretation and Values.The purpose of the study was to investigate some central elements in teenagers’ life interpretation so as to discuss the results in terms of social circumstances in Iceland and of school religious education. The background is that Icelandic society, having been relatively homogeneous, has changed during the past few years with increased plurality.The material the study was based on consists of interviews with Icelandic teenagers. In four articles included in the thesis different parts of the material collected are interpreted using a hermeneutic approach. The main result showed that the teenagers were in a field of tension between homogeneity and plurality on the one hand and security and insecurity on the other. The main trends in the material indicate a common reference framework at the same time as plurality emerges in the teenager’s verbal expressions; and while most spoke of their happiness and security, there was also awareness of the risk and threat that can transform the situation.The material exhibited greater variation within each school than between schools. This suggests the effect of plurality on the younger generation in Iceland. Given this variation among individuals it is urgent to find an approach to religious education that takes greater account of the different pupils’ backgrounds, personal experience and existential questions.

- Context. Accurate transition probabilities for forbidden lines are important diagnostic parameters for low-density astrophysical plasmas. In this paper we present experimental atomic data for forbidden [Fe II] transitions that are observed as strong features in astrophysical spectra. Aims. We measure lifetimes for the 3d(6)((3)G)4s a (4)G(11/2) and 3d(6)((3)D)4s b (4)D(1/2) metastable levels in Fe II and experimental transition probabilities for the forbidden transitions 3d(7) a (4)F(7/2,9/2)-3d(6)((3)G)4s a (4)G(11/2). Methods. The lifetimes were measured at the ion storage ring facility CRYRING using a laser probing technique. Astrophysical branching fractions were obtained from spectra of Eta Carinae, obtained with the Space Telescope Imaging Spectrograph onboard the Hubble Space Telescope. The lifetimes and branching fractions were combined to yield absolute transition probabilities. Results. The lifetimes of the a (4)G(11/2) and the b (4)D(1/2) levels have been measured and have the following values, tau = 0.75 +/- 0.10 s and tau = 0.54 +/- 0.03 s respectively. Furthermore, we have determined the transition probabilities for two forbidden transitions of a (4)F(7/2,9/2)-a (4)G(11/2) at 4243.97 and 4346.85 angstrom. Both the lifetimes and the transition probabilities are compared to calculated values in the literature.

"Utan bok är det ingen riktig undervisning" : En studie av skolkulturella referensramar i sfi

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Experiences of teachers in SFI, Swedish for (adult) Immigrants, indicate that during their schooling earlier in life, SFI students have developed skills, abilities, values, ideas and expectations about teaching and learning that differ somewhat from the prevailing communicative oriented theory of second language teaching which is emphasized in SFI. In the thesis these aspects are referred to as different school cultural frames of reference.The aim of the thesis is to generate knowledge about SFI-students’ school cultural frames of reference of relevance for SFI teaching. The considerable number of immigrants from Iraqi Kurdistan during the 1990s has led to an empirical focus related to this geographical area.From a critical perspective, in some respects a research interest of this kind can be seen as contributing to a division between ‘us’ and ‘them’, in a wider sense a part of exclusion and a maintenance of the segregated Swedish society. In a special section is given an account of this research ethic question, together with arguments from intercultural pedagogy that support a focus on school cultural frames of reference.The theoretical platform for the thesis is sociocultural theory. The concepts of social representations, pedagogical code, classification, framing, power distance, diaspora and distinctions of knowledge also are used.The thesis is based on two data materials. The first consists of data from interviews and talks with students and teachers in SFI, all from Iraqi Kurdistan. The second consists of data gathered through observations, classroom observations, interviews and talks during two visits in the KDP-administrated region of Iraqi Kurdistan, each visit being for a period of about one month. This data material also includes text materials, mainly textbooks in EFL for grade five and six, and course books about EFL teaching used in teacher education.The thesis illuminates several aspects that provide an understanding as to why SFI students from Iraqi Kurdistan can have certain abilities, values, ideas and expectations about teaching, learning materials, learning, teacher and student roles that differ from the communicative oriented second language teaching emphasized in SFI. However, results from the study also underline the importance of a ‘weak’ use of this understanding in a SFI teaching context.

The FERRUM project : experimental and theoretical transition rates of forbidden [Sc II] lines and radiative lifetimes of metastable ScII levels

Tidskriftsartikel (refereegranskat)abstract
- Context. In many plasmas, long-lived metastable atomic levels are depopulated by collisions (quenched) before they decay radiatively. In low-density regions, however, the low collision rate may allow depopulation by electric dipole (E1) forbidden radiative transitions, so-called forbidden lines (mainly M1 and E2 transitions). If the atomic transition data are known, these lines are indicators of physical plasma conditions and used for abundance determination. Aims. Transition rates can be derived by combining relative intensities between the decay channels, so-called branching fractions (BFs), and the radiative lifetime of the common upper level. We use this approach for forbidden [Sc II] lines, along with new calculations. Methods. Neither BFs for forbidden lines, nor lifetimes of metastable levels, are easily measured in a laboratory. Therefore, astrophysical BFs measured in Space Telescope Imaging Spectrograph (STIS) spectra of the strontium filament of Eta Carinae are combined with lifetime measurements using a laser probing technique on a stored ion-beam (CRYRING facility, MSL, Stockholm). These quantities are used to derive the absolute transition rates (A-values). New theoretical transition rates and lifetimes are calulated using the CIV3 code. Results. We report experimental lifetimes of the Sc II levels 3d(2) a(3)P(0,1,2) with lifetimes 1.28, 1.42, and 1.24 s, respectively, and transition rates for lines from these levels down to 3d4s a(3)D in the region 8270-8390 angstrom. These are the most important forbidden [Sc II] transitions. New calculations for lines and metastable lifetimes are also presented, and are in good agreement with the experimental data.
