Hästflickan i rörelse : Generationsberättelser om hästboksläsning
- 2023

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Hästflickan i rörelse: Generationsberättelser om hästboksläsningI vår forskning om hästböcker har vi kommit att intressera oss också för hästboksläsarna. I syfte att få kunskap om varför människor läser hästböcker har vi intervjuat cirka 60 unga och vuxna. Ett delresultat utifrån intervjuer med flickor 9-12 och i vissa fall deras (ibland hästintresserade) föräldrar presenteras. Där framkommer att flickorna i många fall är bokslukare, om än tämligen genretrogna. Ett tydligt samband mellan identiteten som hästtjej och läsare framträder, då läsningen ofta har spin-off-effekter på lekmönster. Orsakerna bakom hästboksläsningen handlar om identifikation i termer av ett flickskap som i stallkulturen står utanför normen och som präglas av mod och beslutsamhet, men där även spänning och kunskapsinhämtning nämns. Hästbokens status har höjts i både skolan och på bibliotek, där den tidigare har haft dåligt rykte, något som kan ses som att större uppmärksamhet ägnas åt något som intresserar många flickor.

A Structural Investigation into the OCV Hysteresis of the Ni(OH)2 Electrode
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Powder X-ray diffraction (XRPD), X-ray absorption spectroscopy (EXAFS and XANES) and Raman spectroscopy were used to study chemical changes in the polycrystalline nickel hydroxide positive electrode material of a NiMH battery at four states of charge: 0%, 50% and 100% charged, and 50% discharged. The two 50% samples were at the same state of charge but in different hysteresis states, manifested by differences in the open circuit potential. The nickel hydroxide electrodes consist of particles in the µm size range, and all measurements were performed ex situ. The material studied was taken from commercial batteries and as such contained both metallic nickel particles, cobalt, and zinc dopants in the active Ni(OH)2 material as well as a cobalt oxide surface layer. Combining the results from all the characterization methods was necessary to better understand the chemistry behind the physio-chemical hysteresis behavior in this complex system. Our results show that there are structural differences between the two 50% samples. Comparison of the XRPD results and the EXAFS results on the nickel edge indicate a presence of the kinetically favored TP2-NiOOH phase in the transition between β-Ni(OH)2 and β-NiOOH and that the amount differs between the two hysteresis states. The measurements on the zinc edge using EXAFS and XANES suggest short range differences in the active material bulk that stems from disorder. Raman spectroscopy measurements show a difference in degree of lithium intercalation in the LiCoO2 surface layer between the hysteresis states. As electrochemistry takes place on the surface of the particles, it is likely that differences in the surface structure are responsible for the open circuit voltage hysteresis. However, due to the coherence of the structure differences detected, it is probable that they are all connected and have a part in the observed behavior.

Konsten att undervisa ryttare : En studie om ridlärares pedagogiska praktik
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis concerns how riding teachers’ reflect upon their teaching and how they teach. The overall aim of the thesis is to contribute with knowledge about how riding lessons are organized, regarding both the accomplishment of lessons as activity systems and the interactional organization of instructional work. Horseback riding can be understood as an embodied and practical knowledge, and includes communication and collaboration between horse and rider, sometimes referred to as equestrian feel (Dashper, 2016). Two different theoretical perspectives were applied to explore how such knowledge is taught. Activity theory (Engeström, 1987) was used to analyze interviews with and observations of ten riding teachers about their understanding and implementation of their pedagogical practice. Teachers’ and students’ interactions during riding lessons were examined using an ethnomethodological and conversation analytic approach (Goodwin, 2000; Schegloff, 1996). The analyses were based on video-recordings of ten group lessons and 40 one-on-one riding lessons.The results show that riding lessons can be conceptualized as activity systems where the focus of teaching constantly changes; from horse to student to routine. Traditions and safety regulations are shown to generate contradictions that may hinder the teachers from developing their teaching. However, the teachers express a wish to use more student collaborative methods, and display an intention to communicate with students about equestrian feel. Another result unveils how the teacher and the individual students, within the mobile context of riding lessons, make instructional sequences possible by co-creating instructional spaces. A third result illuminates the participants’ collaborative work to make equestrian feel available for instruction. The teacher molds equestrian feel through online instructions, i.e., instructions produced during the students’ active riding. These instructions shift focus between the students’ seat and influence, the horse’s actions and the student’s embodied feel. Moreover, the teachers are shown to use visual, verbal and embodied resources as they interpret equestrian feel for the student. In sum, the studies shed light on the complex art of teaching practical and embodied knowledge of riding.

Historia i futurum : Progression i historia i styrdokument och läroböcker 1919-2012
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Facing an unknown future, the meaning of history is not primarily a fixed set of knowledge about the past, but a well-developed historical consciousness. This is a generic skill, emanating from an understanding of history as something that we are, and at the same time as something that we create. From a historical-cultural perspective, the learning process can be described with a point of departure in questions stemming from the life- and experience-world, looking genealogically toward the past. With a point of departure in pedagogical theories of the learning process, and a development described as fact, interpretation and consciousness, the question follows as to how the development is expressed in the curricula and textbooks in school between 1919 and 2012 and how studying history can contribute to the progress as it is described above. A number of dichotomies have been identified as tools of analysis, describing the space of interpretation between history as science and history as life- and experience-worlds. The goal is a well-developed historical consciousness defined as the ability to simultaneously interpret the past, understand the present and have perspectives on the future.
