Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Swedish compulsory school has recently been subjected to a number of political reforms. Between 2011 and 2014, for example, earlier grades, more national tests and a new curriculum plan (Lgr 11) were to be implemented. This thesis aims to examine those changes as they were experienced by teachers who teach history in Swedish upper primary schools. The theoretical framework is in-spired by existential philosophy, primarily as formulated in the works of Martin Heidegger and Hanna Arendt. In this way, the study highlights the teachers’ lived experience by making use of the concepts yearning, appearance, acting and mood.The study comprises of 36 interviews with 26 informants. The interviews were carried out and transcribed during 2014. The questions focus on both the existential being of the teachers’ lives as well as the ideological function of the history subject. This highly renders in the issue of how lived experiences of a specific school reform corresponded to the teachers’ own perception of a mean-ingful history education. Both the yearnings that were expressed by the participants and their de-scriptions of what they have experienced, have been related to the overall educational ideological functions stated by Gert Biesta (socialisation, subjectification and qualification) and Jonas Aspelin (existentialisation).Although the teachers’ narratives were greatly varied in some aspects, their interpretations of the new assignment seemed to be quite homogenous. Most of the teachers portrayed a situation characterised by performativity. Measurable knowledge and more frequent documentation seemed to be prioritised. Some of them stressed that they experienced less autonomy. In terms of history, the new curriculum was associated with more content knowledge, cognitive skills and procedural abilities. From the teachers’ perspective, pure qualification, rather than subjectification and social-isation, characterised the new curriculum.Still, the teachers’ feelings towards the curricular changes showed a great deal of divergence. Some of them embraced most of the new aspects. They claimed that clearly formulated require-ments in the history curricula provided them with security. They declared that their history teaching to some extent became more professional. In line with such beliefs, some teachers asserted that the strengthened focus on analytical skills improved their teaching. Particularly those who ex-pressed that they preferred such analytic procedural approaches described their experience in terms of confirmation and approval. Others appeared to struggle with the changes. While a few teachers even tried to resist the curricular changes, some found themselves forced to endure what appeared to be a totally new situation. They expressed disbelief, frustration and pain. Notably it was those most devoted to the existentialisational function of history teaching that usually seemed to express such alienation. As argued, they appeared to long for a lost possibility to engage their pupils, to bring history alive and to make meaning of the past.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Inom lärarutbildningen vid Högskolan i Halmstad har handledning och examination av lärarstudenternas examensarbete nyligen förändrats. Studenterna handleds nu i grupper av handledarpar, vilka i sin tur ingår i ett lag som coachas av en kollega. Examinationen av examensarbetena har också förändrats i och med att examinatorer som är externa i förhållande till handledningen införts. Vidare har nya bedömningskriterier utarbetats som skärpt de vetenskapliga kraven och tydliggjort kraven i fråga om examensarbetenas ämnesdidaktiska implikationer och skolverksamhetsrelevans. Slutligen har lärare, rektorer och andra aktörer i för-, grund- och gymnasieskolor engagerats som medreflektörer, vilka ger kollegiala kommentarer till lärarstudenternas examensarbeten. Föreliggande text syftar för det första till att beskriva detta nya sätt att handleda och examinera examensarbeten. För det andra syftar texten till att kritiskt reflektera över handledning och examination i ljuset av dels lärarutbildningens ovanligt spänningsfyllda karaktär, dels dess speciella studiekultur.

Magnetoresistance and Space : Micro- and Nanofeature Sensors Designed, Manufactured and Evaluated for Space Magnetic Field Investigations
- 2011

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In recent years, the interest for miniaturization of spaceborne instruments and subsystems has increased steadily, as this enables development of small and lightweight satellite classes as well as more versatile payloads on traditional spacecraft. In essence, this thesis work is an investigation of the applicability of magnetoresistive technology to a magnetometer intended for space. Two types of magnetoresistive sensors, promising with respect to performance competiveness also after considerable miniaturization, were developed and evaluated, namely magnetic tunnel junctions and planar Hall effect bridge sensors. In the case of the magnetic tunnel junctions, much effort was put on the micromanufacturing process. Two schemes were developed and evaluated for sensor contouring: one employing focused ion beam processes for rapid prototyping, and the other combining sputtering and x-ray photoelectron spectroscopy for precise etch depth monitoring during ion etching. For the former, the resulting implantation damages were investigated with chemical analysis and correlated to the sensor properties. In the latter, the depth of the etching was monitored live with a resolution sufficient to stop the etching in the 1 nm thick tunneling barrier. The effect and extent of redeposition were investigated by transmission electron microscopy and micromagnetic analysis. With the knowledge so gained, the tunneling magnetoresistance of the manufactured junctions could be improved significantly and their inherent noise could be reduced. As a step in space flight qualification, the magnetic tunnel junctions were subjected to both g and particle radiation, leaving them unaffected by the first, but rendering them a reduced tunneling magnetoresistance ratio and an increased coercivity by the latter. In the case of the planar Hall effect bridge sensors, their inherent noise was thoroughly investigated, revealing both electric and magnetic 1/f noise at low frequencies along with thermal noise at higher frequencies. In addition, an analytical model of the magnetic properties of the planar Hall effect bridges was developed, and a design process, based on the model, was established to optimize the bridges for a particular application. In conclusion, both types of sensors show great promises for use in space. Of the two, the planar Hall effect bridge sensors had a better detection limit at low frequencies, whereas the magnetic tunnel junctions were more precise at higher frequencies. However, both sensors had a bandwidth greatly exceeding that of traditional spaceborne magnetometers. A magnetometer employing the magnetic tunnel junctions from this work is currently included as payload onboard the Vietnamese satellite F-1 scheduled for launch this year. A magnetometer using magnetoresistive sensors – planar Hall effect sensors, magnetic tunnel junctions, or both – enables a mass reduction of more than two orders of magnitudes compared with traditional systems.

Recension (populärvet., debatt m.m.)abstract
- Managementböckerna fortsätter att strömma ut på marknaden. I mångfalden är det givet att man finner en och annan bra och en och annan dålig bok. Ingvar & Sandberg lanserar inte mycket nytt, utan förmår endast knyta an till en idag ganska kraftlös sociobiologisk trend. Bennis & Nanus bryr sig inte så mycket om trender. De har en självständighet i sitt sökande efter ledarskapets "själ"... Jag tror att de skapar en ny trend med sitt envisa hävdande att makten är ledarskapets viktigaste förutsättning.
