Tove Jansson (1914--2001) was a Finnish illustrator, author, artist, caricaturist and comic artist. She is best known for her Moomin Books, written in Swedish, which she illustrated herself, and published between 1945 and 1977. My study focuses on the interweaving of images and words in Jansson s picturebooks, novels and short stories situated in the fantasy world of Moomin Valley. In particular, it concentrates on Jansson s development of a special kind of aesthetics of movement and stasis, based upon both illustration and text. The conventions of picturebook art and illustration are significant to both Jansson s visual art and her writing, and she was acutely conscious of them. My analysis of Jansson s work begins by discussing her first published picturebooks and less familiar illustrations (before she began her Moomin books) and I then proceed to discuss her three Moomin picturebooks, The Book about Moomin, Mymble and Little My; Who Will Comfort Toffle?, and The Dangerous Journey. The discussion moves from images to words and from words to images: Barthes s (1982) concept of anchoring and, in particular, what he calls relaying , form a point of reading and viewing Moomin texts and illustrations in a complementary relation, in which the message s unity occurs on a higher level: that of the story, the anecdote, the diegesis . The eight illustrated Moomin novels and one collection of short stories are analysed in a similar manner, taking into account the academic discourse about picturebooks which was developed in the last decade of the 20th century and beginning of the 21st century by, among others, scholars such as Nodelman, Rhedin, Doonan, Thiele, Stephens, Lewis, Nikolajeva and Scott. In her Moomin books, Jansson uses a wide variety of narrative and illustrative styles which are complementary to each other. Each book is different and unique in its own way, but a certain development or progression of mood and representation can be seen when assessing the series as a whole. Jansson s early stories are happy and adventurous but her later Moomin novels, beginning from Moominland Midwinter, focus more on the interiority of the characters, placing them in difficult situations which approximate social reality. This orientation is also reflected in the representation of movement and space. The books which were published first include more obviously descriptive passages, exemplifying the tradition of literary pictorialism. Whereas in Jansson s later work, the space develops into something that is alive which can have an enduring effect on the characters personalities and behaviour. This study shows how the idea of an image a dynamic image -- forms a holistic foundation for Jansson s imagination and work. The idea of central perspective, or frame, for instance, provided inspiration for whole stories or in the way that she developed her characters, as in the case of the Fillyjonk, who is a complex female figure, simultaneously frantic and prim. The idea of movement is central to the narrative art of picturebooks and illustrated texts, particularly in relation to the way that action is depicted. Jansson, however, also develops a specific choreography of characters in which poses and postures signify action, feelings and relationships. Here, I use two ideas from modern dance, contraction and release (Graham), to characterise the language of movement which is evident in Jansson s words and images. In Jansson s final Moomin novels and short stories, the idea of space becomes more and more dynamic and closely linked with characterisation. My study also examines a number of Jansson s early sketches for her Moomin novels, in which movement is performed much more dramatically than in those illustrations which appeared in the last novels to be published.

The use of head-mounted displays (HMDs) can produce both positive and negative experiences. In an effort increase positive experiences and avoid negative ones, researchers have identified a number of variables that may cause sickness and eyestrain, although the exact nature of the relationship to HMDs may vary, depending on the tasks and the environments. Other non-sickness-related aspects of HMDs, such as users opinions and future decisions associated with task enjoyment and interest, have attracted little attention in the research community. In this thesis, user experiences associated with the use of monocular and bi-ocular HMDs were studied. These include eyestrain and sickness caused by current HMDs, the advantages and disadvantages of adjustable HMDs, HMDs as accessories for small multimedia devices, and the impact of individual characteristics and evaluated experiences on reported outcomes and opinions. The results indicate that today s commercial HMDs do not induce serious sickness or eyestrain. Reported adverse symptoms have some influence on HMD-related opinions, but the nature of the impact depends on the tasks and the devices used. As an accessory to handheld devices and as a personal viewing device, HMDs may increase use duration and enable users to perform tasks not suitable for small screens. Well-designed and functional, adjustable HMDs, especially monocular HMDs, increase viewing comfort and usability, which in turn may have a positive effect on product-related satisfaction. The role of individual characteristics in understanding HMD-related experiences has not changed significantly. Explaining other HMD-related experiences, especially forward-looking interests, also requires understanding more stable individual traits and motivations.

The aim of this thesis was to study what kind of home-made menstrual pads were used in the early 20th century in Finland, how the home-made pads were made and which techniques and materials were used. The use and taking care of menstrual pads were also explored. The history of menstrual pads has been studied in Sweden, Germany and United States but none of those studies has concentrated on home-made pads. Instead, there are many studies about womanhood and menstruation. In many studies home-made menstrual pads are only briefly mentioned. Menstrual pads were not commonly used in Finland at the beginning of the 20th century, but already in the 1940s the use of menstrual pads had become common in every stratum of society. Home-made menstrual pads were used even until the 1960s. In Finland, factory-made disposable menstrual pads became common only in the 1930s and they were only slowly accepted. The study material consisted of nine interviews, three archival inquiries, health care guidebooks from 1893 to 1943 and authentic menstrual pads, menstrual belts and other objects related to them. The interviewed women were born between 1915 and 1939. The narrative approach was used in the study and it also guided the analysis. The interview and archival data were studied according to the basic rules of oral history studies. Literature consisted of publications from several disciplines. The extensive primary material played the most important role in this study. The reconstructions of the menstrual pads were made according to the interviewed women s advice. In Finland there were innumerable variations of home-made menstrual pads. The pads were most commonly crocheted and knitted either by hand or by knitting machine. Pads were also sewn of cloth, old bed linen or old underwear. The menstrual pads were self-made or made by a female relative. Word of mouth was important in spreading information on how to make pads, because there were hardly any instructions available. The biggest pads were 54 cm long and 13 cm wide. The most widely used pad model was a rectangle, which had triangle-shaped ends with a buttonhole or a loop. The pad was attached to the menstrual belt or to the buttons of the suspender belt. Knitted and crocheted pads had one, two or three layers. In sewn pads, there could be even more layers. Cellulose wadding or pieces of cloth could be placed inside the pad to increase the absorption ability. The experiences of the comfort of self-made pads varied. The crocheted and sewn pads were found chafing, knitted ones were found soft and comfortable. The menstrual pads were laborious to wash and boil in lye water. Therefore disposable pads made everyday life easier. The home-made menstrual pads were part of a unique tradition of handicrafts and folk culture. Hand-made pads were one of the most common handicraft products and were a part of every woman s life. Even so, the menstrual pads were unnoticeable. The large number of variations was probably caused by the silence around menstrual topics and by the lack of instructions for making pads. Variations are also explained by the uniqueness of every handicraft product. In Finland the home-made pads were used until relatively recent times. This was caused by the conditions of wartime and the following years and the rarity of commercial pads. Furthermore, until the late 20th century Finland was an agricultural society where all innovations spread slowly. Home-made menstrual pad was a secret handicraft of women and every woman needed to know how to make it by herself.

The importance of lying behavior to dairy cows and the feasible definition of lying has attracted many studies on the subject. Cattle show both behavioral and physiological stress responses when subjected to thwarting of their lying behavior. If cows are unable to lie down they later compensate for lost lying time when possible. Environmental factors such as housing and bedding systems have been noted to affect the time spent lying, but there is usually large variation in lying time between individuals. Internal factors such as the reproductive stage, age and health of cows affect their lying time and can cause variation. However, the effect of higher milk production on behavior has not previously been illuminated. The objective of this study was to provide data applicable for the improvement of resting conditions of cows. The preference of stall surface material, differences in normal behavior per unit time and various health measures were observed. The aim was to evaluate lying behavior and cow comfort on different stall bedding materials. In addition, the effect of milk yield on behavior was examined in a tie stall experiment. The preferences for surface materials were investigated in 5 experiments using 3 surface materials with bedding manipulations. According to the results, the cows preferred abundant straw bedding and soft rubber mats. However, they showed an aversion to sand bedding. Some individuals even refused to use stalls with sand when no organic bedding material was present. However, this study was unable to determine the reason for the avoidance, as neither the sand particle size nor thermal properties appeared critical. However, previous exposure to particular surface materials increased the preference for them. The amount of straw bedding was found to be an important factor affecting the preferences for stalls, and the lying time in stalls increased when the flooring softness was improved by applying straw or by installing elastic mats. Despite sand being the least preferred flooring material in preference tests, the health of legs improved during exposure to sand-floored stalls. Moreover cows using sand were cleaner than those that used straw stalls. Thus, sand bedding entailed some health benefits despite the contradictory results of preference tests, which more strongly reflected the perceptions of individual animals. Milk yield was observed to affect behavior by reducing the lying time, possibly due to factors other than longer duration of eating. High yielding cows seemed to intensify their lying bouts, as they were observed to lie with the neck muscles relaxed sooner after lying down than lower yielding cows. In conclusion, cows were found to prefer softer stall surface materials and organic bedding material. In addition, the lying time was reduced by a high milk yield, although the lying time seemed to be important for resting. Cows might differ in the needs for their lying environment. The management of dairy cows should eliminate any unnecessary prevention of lying, as even in tie-stalls high yielding cows seem to be affected by time constraints. Adding fresh bedding material to stalls increases the comfort of any stall flooring material.

For the past decades reflection has been the buzzword of adult and higher education. Reflection is facilitated in many practices and there is abundant research on the issue. Despite the popularity of the concept, the reasons why bringing about reflection in educational practices is difficult remain unclear. The prevailing theories inform of the process in its ideal form. However, to a great extent, they fail to offer conceptual tools for understanding and working with the actualities of reflection. The aim of the doctoral thesis was to explore the challenges and prerequisites of reflection in order to theorize the nature of reflection. By the term reflection it is here referred to becoming aware of and questioning the assumptions that orient our thinking, feelings and actions. The doctoral thesis consists of five studies that approach these questions from different viewpoints and within different contexts. The methods involve both a philosophical and an empirical approach. This multifaceted approach embodies the aim of both gaining a more thorough grasp of the phenomenon and to develop the methodology of researching reflection. The theory building is based on conceptual analysis and rational reconstruction (see Davia 1998; Habermas 1979; Rorty1984) of Mezirow s (1981; 1991; 2000; 2009) theory of transformative learning. In order to explore the aspects which, based on the analysis, appeared insufficiently considered within Mezirow s theory, Damasio s (1994; 1999; 2003; 2010) theory on emotions and consciousness as well as Clausewitz s (1985) view on friction are used as complementary theories. Empirical analyses are used in dialogue with the theoretical, in order to challenge and refine the emerging theorization. Reflection is examined in three different contexts; regarding university teachers pedagogical growth, involuntarily childless women recovering from a life-event crisis, and soldiers preparing to act in chaotic situations of the battlefield as well as recovering from it. The choice of these contexts is based on Mezirow s notion of disorienting dilemma as a trigger for reflection. This notion indicates that reflection may more naturally emerge in association to life-event crises or other cumulative sets of instances, which bring our worldview and beliefs under question. Nevertheless, reflection is often being promoted in educational contexts in which the trigger conditions may not readily prevail. These contextual issues as well as the differences between the facilitated and non-facilitated contexts have not, however, been considered in detail within the research on reflection (or transformative learning). The doctoral thesis offers a new perspective into reflection which, as a further development on Mezirow s transformative learning theory, theorizes the nature of reflection. The developed theory explicates the prerequisites and challenges to reflection. The theory suggests that the challenges of reflection are fundamentally connected to the way the biological life-support system affects our thinking through emotions. While depicting the mechanisms that function as a counterforce to reflection, the developed theory also opens a perspective for considering possibilities for carrying out reflection, and suggests ways to locate and deal with the assumptions to be reflected on. The basic dynamic of the challenges to reflection was explicated by conceptually bridging the gap between Mezirow s and Damasio s theories, through exploring the connections between the meaning perspective and the biological functions of emotions. The concepts of comfort zone and edge-emotions were formed so as to depict the emotional orientation of our thinking, as part of the explanation of the nature of reflection.
