- More than 8 million people fly on commercial aircraft each day with approximately 5% having a pre-existing respiratory disease. Thus it is necessary to provide high air quality in aircraft to protect public health. Volatile organic compounds (VOCs) present in aircraft cabins are suspected to contribute to the reported complaints. We investigated concentrations of VOCs, air temperature, relative humidity, and CO2 concentrations in a total of 46 flights, including 26 Chinese domestic flights and 20 international flights. We focused on the data from the cruising phase without meal serving in which the air supply and air recirculation were steady. A total of 284 passengers (i.e., 101 on international flights and 183 on Chinese domestic flights) were invited to participate in questionnaire surveys in this phase. We performed a linear mixed model analysis by controlling for potential confounders (age, gender, smoke habits, and history of allergy) to study associations between VOCs exposures and passengers' complaints. Xylene was significantly associated with irritations of the eyes, nose, and throat on both international and domestic flights, with antilog beta values from 1.12 to 1.28 (p < 0.05). The association of some aldehydes (i.e., nonanal, decanal, and heptanal), which are potential oxidation products with ozone, with passengers' sensory irritations was also significant, especially during international flights (antilog beta values: 1.19-1.22). It indicates that VOCs, especially xylene and aldehydes, in aircraft cabins may influence the perceived indoor air quality and complaints among passengers.

Arm Posture Changes and Influences on Hand Controller Interaction Evaluation in Virtual Reality
- 2022

Ingår i: Applied Sciences. - : MDPI AG. - 2076-3417. ; 12:5

Tidskriftsartikel (refereegranskat)abstract
- In virtual reality (VR) applications, hand-controller interaction is largely limited by the biomechanical structure of the arm and its kinematical features. Earlier research revealed that different arm postures generate distinct arm fatigue levels in mid-air operational tasks; however, how they impact interaction performance, e.g., accuracy of target grasp and manipulation, has been less investigated. To fill this gap in knowledge, we conducted an empirical experiment in which thirty participants were recruited to complete a series of target acquisition tasks in a specifically designed VR application. Results show that (1) a bent arm posture resulted in a higher interaction accuracy than a stretched arm posture; (2) a downward arm posture interacted more accurately than an upraised arm posture; since two arms are bilaterally symmetric, (3) either selected arm interacted more accurately on the corresponding side than on the opposite side; and (4) the user-preferred or dominant arm interacted more persistently than the non-dominant one, though two arms generated little difference in interaction accuracy. Implications and suggestions are discussed for designing more efficient and user-satisfying interactive spaces in VR.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- “Absent presence”: female narrative strategies in modern Polish literatureThe culture of the nobility, with their strong influence in forming Poland’s very special mentality, established the Polish view of the woman and her role in society. What is particularly characteristic of women’s position in Poland still today is the notion of the inherent nature of femininity and the idea that a woman’s purpose is first and foremost to be a mother. The Polish woman symbol has another specific dimension, the strongly emotional image of “The Polish Mother” (Matka-Polka), who – like the Virgin Mary – unselfishly sacrifices her own child not just for the common good but, in Poland’s case, for the fatherland that has endured centuries of suffering. This determines the Polish view of women in general and the Polish woman’s self-image: she knows that she is expected to fulfil the traditional feminine scenario. It is this very old tradition that makes the “feministic” problem, in all its different senses, still a very controversial issue in Polish cultural and literary contexts. Herein lies a powerful reason for the restrictive, reserved way that “femininistic” themes have been and still are treated in Polish literature, which is heard clearly in discussions of the works by young Polish female writers. Several of these works published in the beginning of the 1990s made an attempt to re-evaluate the traditional image of women in Polish literature. Portrayals of women by Izabela Filipiak, Manuela Gretkowska, Natasza Goerke and Olga Tokarczuk especially deviate from the traditional figures in earlier Polish literature.In their view of the world and in their narrative strategies, these writers have more or less unconsciously distanced themselves from tradition and created their own means of approaching “woman” and “femininity”. A distinguishing feature here is that their strategies are all characterised by a kind of narrative and linguistic mimicry. Borrowing Luce Irigaray’s term, one might be tempted to claim that they represent the “female mimicry of male discourse” and thus through this kind of mimetism (or its parody) disrupt patriarchal logic. As Irigaray argues, “To play with mimesis is thus, for a woman, to try to recover the place of her exploitation by discourse, without allowing herself to be simply reduced to it.” The focus in this discussion is on the works of Natasza Goerke and Olga Tokarczuk. They belong to the same generation of writers, and both take a stand against the new feministic trends in Polish literature, although their ways of using and treating the “feminine” aspect are very different. Their female characters have one thing in common: they live in a society run by men. Aware of this unjust division and treatment, these authors bring up, convey and defend the nature and rights of femininity in their writing – albeit in different ways.In a similar way, Goerke and Tokarczuk realise that the only way to get at and decode the deeply rooted and obsolete ideals and notions about the differences between the sexes is to attack their reflection in the cultural stereotypes and national myths, where foremost Mother Poland and motherhood have their given places. When Goerke and Tokarczuk take the somewhat Promethian role of speaking in the name of women and femininity, they see all these banal patterns as their greatest opponents. At the same time, however, they use protective masks and manoeuvers to be able to put a distance between themselves and the reality they describe. Their “feminine mimicry” is however expressed – as I try to argue – in a completely different way. Goerke takes on the male perspective in her narrative worlds. This mimicry that Goerke uses to keep at arm’s length from these ideas allow her to go over the boundaries of the feminine, staked out by culture and tradition, and make the cultural absurdities of Poland come out even more clearly and sharply. Tokarczuk’s writing is somewhat different. Her approach to patriarchal stereotypes and male values is more of the “non-aggressive” type, almost quiet. This does not mean that Tokarczuk does not take up the fight against these stereotypes and patterns that devalue women, but she does this in quite another way. Her mimicry is made up of a conscious mythologising and even a re-sacralisation of the female sphere she describes. Goerke’s and Tokarczuk’s books deal not only with a position of resistence toward patriarchal stereotypes and male values in Polish literature. Their works also put forth a female perspective in the literature under consideration – it is “women’s femininity” that is discussed and uncovered in all its vulnerability. The works of these authors were created under the influence of the past decade’s feminist debates in Poland and in opposition to the strong patricharchal tradition. Goerke’s and Tokarczuk’s literary strategies and protective narrative manoeuvers thus give us a salient example of how difficult is the woman’s path, from a position of subordination dictated by tradition, to freedom; especially in a country that is so strongly formed by the burden of its history.

Exploring a framework for technology integration in the mathematics classroom
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this paper is to investigate the potential of Ruthven’s (2009) framework the Structuring Features of Classroom Practice (SFCP) as a tool for analyzing empirical data in order to conceptualize and analyze teachers’ reasoning about technology integration in the mathematics classroom. The framework is tested on interview data from a Swedish design research project seeking to develop design principles for CRS tasks. The results show that the framework captures a large part of teachers’ ways of reasoning, while the parts it does not capture are related to students’ attitudes and behaviors. If the SFCP framework aims at capturing key features of classroom practice and is to be built on a system of constructs closer to the ‘lived world’ of teacher experience and classroom practice, it would benefit from an extension.
