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.

Konferensbidrag (refereegranskat)abstract
- This paper presents the results of a pilot study including a questionnaire and semi-structured interviews with riders about their reading of horse stories. The data has been collected at an equestrian center in Sweden. The informants are active at the riding center and thus of various ages, although approximately 75 percent are 20 years old or more. They have been asked questions on their reading habits when it comes to horse stories, at present or at earlier stages in their lives. Interviews are ongoing but results are expected to come in the next couple of months. The purpose of the interviews is foremost to enter more deeply into the informants’ reading of horse stories.Tentative results show that 80 percent of the informants read horse stories in the age between 8 to 12 years. 75 percent of the adults report that they used to read horse stories either every day or between one and three times per week in that particular age. 60 percent state that horse stories were important for them since they got the opportunity to dream away, identify themselves with the characters and relate to their own experiences from the equestrian settings, to learn new things about horses and riding and, finally, as a reaction to the fact that they could not spend as much time in the stable as they would have preferred. In addition, a majority of the informants suggest that horse stories could be used at equestrian centers, for both educational and relaxational reasons.

HIF-2 alpha Expression Is Suppressed in SCLC Cells, Which Survive in Moderate and Severe Hypoxia When HIF-1 alpha Is Repressed

- Small cell lung carcinoma (SCLC) is extremely aggressive and frequently metastasizes widely in its early stage. Because tumor hypoxia is related to aggressive tumor behavior and the hypoxic adaptation of SCLC is poorly documented, we stained SCLC tumors arranged in a tissue microarray for hypoxia-inducible factor (HIF)-1 alpha and HIF-2 alpha proteins. We found an overall lack of HIF-2 alpha protein expression, which was confirmed in large tumor sections. HIF-1 alpha protein was strongly expressed in most tumors, frequently adjacent to necrotic regions. In concordance, cultured SCLC but not non-small cell lung carcinoma cells showed no or extremely low levels of HIF-2 alpha mRNA and no HIF-2 alpha protein at hypoxia. HIF-1 alpha was stabilized after 4 hours at hypoxia, and its accumulation increased up to 96 hours. SCLC cells survived well and showed net proliferation and low cell death in modest (1% oxygen) and severe (0.1% oxygen) hypoxia. HIF-1 alpha repression virtually did not influence cell death or viability despite reduced levels of hypoxia-inducible genes, such as BNIP3 and BNIP3L. At 1% oxygen no increased autophagy (LC3B-II activation) or NF-kappa B signaling were detected, whereas the unfolded protein response was activated at severe hypoxia. Our data indicate that HIFs are not exclusively required for SCLC cell survival at modest or severe hypoxia and that additional, yet uncharacterized, hypoxia-driven adaptation pathways may become activated.

- Produced as a tissue defence response to hypoxia and inflammation, growth differentiation factor-15 (GDF-15) is elevated in people receiving metformin treatment. To gain insight into the relationship of GDF-15 with metformin and major cardiovascular risk factors, we analysed the data from the SUMMIT cohort (n = 1438), a four-centre, nested, case–control study aimed at verifying whether biomarkers of atherosclerosis differ according to the presence of type 2 diabetes and cardiovascular disease. While in univariate analysis, major cardiovascular risk factors, with the exception of gender and cholesterol, increased similarly and linearly across GDF-15 quartiles, the independent variables associated with GDF-15, both in participants with and without diabetes, were age, plasma creatinine, N-terminal pro-brain natriuretic peptide, diuretic use, smoking exposure and glycated haemoglobin. In participants with diabetes, metformin treatment was associated with a 40% rise in GDF-15 level, which was independent of the other major factors, and largely explained their elevated GDF-15 levels. The relatively high GDF-15 bioavailability might partly explain the protective cardiovascular effects of metformin.

In the Company of Horses : Girlhood in Pia Hagmar’s Series about Klara
- 2021
-
Ingår i: Book of Abstracts. ; , s. 26-26, s. 26-26
-
Konferensbidrag (refereegranskat)abstract
- This paper deals with the literary representation of the relationship between humanand horse, in parallel to the main character’s construction of identity as a girl. Thematerial used will be Pia Hagmar’s series on Klara, which consists of eighteenbooks published between 1999 and 2008. Previous studies (Hedenborg 2013;Asklund 2013) have focused on the identity construction of the horse girl in relationto norms, hard work and her peers. This paper will take a slightly differentorientation, concentrating on the relationship Klara develops with different horsesalong the series, and their impact on her identity as a girl. The main theoreticalframework will be ecocriticism and its entanglements with posthumanism andanimal studies. From an ecocritical standpoint, the anthropocentric perspectivedominates human discourse about other beings, and within this logic, a way ofunderstanding the animal other is to impose anthropomorphism, assigning humantraits to it, explaining its behavior via words, feelings and explanatory modelsproper to humans. Within posthumanism and animal studies, there is a questioningof traditional dichotomies, such as nature-culture, suggesting the upheaval ofanthropocentrism and working towards a greater equality between human andnonhuman animals. Donna Haraway’s notions of companion species andsignificant otherness will be used to talk about the interspecies relationshipsdeveloped within the series. Identity formation in relation to another species is whatis at stake in this paper, where the aim is to show how Klara’s identity formationis interconnected with the horses that she encounters.

`When We Ride Together, She’s More like a Friend than a Mum´ : Mothering Variations in Three Horse Story Series by Pia Hagmar
- 2024
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This article analyzes how the horse story setting problematizesthe conception of the good mother and normative mothering, by elucidatinghow the gazes of the young main characters on their mothers function inrelation to the notion of the good mother, how this influences the motheringand how the mothering characters challenge this notion. Mothering is seenhere as caring practices, which can be performed by people other than moth-ers. The analysis of three horse story series by Pia Hagmar, the books onKlara (1999–2008), the books on Millan (2012–2014) and the books on Juli(2019–2021), shows that the series depict motherhood and mothering at theintersection between the conception of the good mother and the good horseperson. The common denominator is nurturing traits that make personalneeds take the back seat – for the traditional good mother to the benefit ofher children, for the good horse person to the benefit of the horse. Hagmarnormalizes the presence of several mothering characters in addition to theirmothers around the horse girls. Furthermore, these characters, who func-tion as mothering variations, contribute to the creation of a solid caringenvironment, reducing the demands on mothers who try to be everythingto their children. Although the daughters’ views of their mothers are some-times critical, Hagmar allows the mothers to be imperfect, partly incompe-tent, or simply women with their own agency,interests and needs outside ofmotherhood. In addition, a mother-daughter relationship built on a commoninterest in horses allows for a friendship with a common focus – the horse.

- To compare speech outcome following different sequencing of hard and soft palate closure between arms and centers within trial 3 and compare results to peers without cleft palate.A prospective randomized clinical trial.Two Norwegian and 2 British centers.One hundred thirty-six 5-year-olds with unilateral cleft lip and palate were randomized to either lip and soft palate closure at 3 to 4 months and hard palate closure at 12 months (arm A) or lip and hard palate closure at 3 to 4 months and soft palate closure at 12 months (arm D).A composite measure of velopharyngeal competence (VPC), overall assessment of VPC from connected speech (VPC-Rate). Percentage of consonants correct (PCC), active cleft speech characteristics (CSCs), subdivided by oral retracted and nonoral errors, and developmental speech characteristics (DSCs).Across the trial, 47% had VPC, with no statistically significant difference between arms within or across centers. Thirty-eight percent achieved a PCC score of >90%, with no difference between arms or centers. In one center, significantly more children in arm A produced ≥3 active CSCs (P < .05). Across centers, there was a statistically significant difference in active CSCs (arm D), oral retracted CSCs (arm D), and DSCs (arms A and D).Less than half of the 5-year-olds achieved VPC and around one-third achieved age-appropriate PCC scores. Cleft speech characteristics were more common in arm A, but outcomes varied within and across centers. Thus, outcome of the same surgical method can vary substantially across centers.
