  • Above Ground Durability of Swedish Softwood
  • 2005
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This thesis describes aspects of durability of Swedish softwood in above ground applications. The thesis consists of a summary of nine papers, which all aim to explain the existing variation in above ground microbial durability and moisture sensitivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris). The methods used were two field tests, one accelerated durability test, and three water permeability tests. The main conclusions made in the study were that Norway spruce sapwood is more susceptible to discolouring fungi than heartwood. With respect to Scots pine, the only important factor for its natural durability above ground was whether the samples consisted of heartwood or of sapwood. There was also no systematic variation between pine heartwood from different stand origins in above ground conditions. Origin had no influence on durability in practice for neither spruce nor pine. Furthermore, in contradiction with traditional thinking, annual ring width and density had no influence on durability in any of the tests. The material came from two different samplings. The ‘old’ material was sampled in the beginning of the 1980s and consisted of Scots pine and Norway spruce from three different origins: the north, the central area, and the south of Sweden. The material was subjected to different handling conditions and surface and end-grain treatments. The ‘old’ material was used in a large above ground field test, carried out between 1985 and 1994. Unfortunately, the spruce sapwood and heartwood was not separated in this field test. In the field trial with the ‘old’ material, the most important factor for the durability of Norway spruce was the samples’ surface- and end-grain treatment. It was also observed that untreated spruce showed better durability than samples that were painted but without proper end-grain treatment. Samples originating from one of the stands were more sensitive towards air-drying than samples from the other two, which was reflected in a higher average moisture content and mass loss for the untreated samples. With respect to Scots pine, the most important factor was whether the sample consisted of heartwood or of sapwood. The heartwood samples were durable irrespective of their previous treatment. The Scots pine sapwood samples, on the other hand, had a very fluctuating moisture content if they were not surface- and end-painted. This was also reflected in higher mass losses in these samples. Even when properly surface- and end grain treated, the sapwood samples did not perform as well as the heartwood samples. The ‘new’ material consisted of Scots pine taken from six different stands, and Norway spruce from five different stands, all from areas in southern Sweden. The sampling was performed in order to achieve a large variation in wood properties. Thus, logs from areas with different climate and growth conditions were collected. This material was used for laboratory tests, and also for the second field test, which was evaluated after a test period of two years. In the second field test untreated Scots pine and Norway spruce samples from the ‘new’ material were investigated. Effects of origin and different tree diameters were examined. Furthermore, Scots pine was separated to heartwood and sapwood, and Norway spruce to mature and juvenile wood. The Norway spruce samples were sawn with vertical or horizontal annual rings. For the Norway spruce in the second field test, vertical annual rings were shown to be very beneficial for avoiding crack formation, while samples with horizontal annual rings displayed a large number of cracks. Despite this, the larger number of cracks did not result in a higher moisture content or more fungal discoloration. Juvenile wood had a slightly higher average discolouring fungal growth grading than the other spruce samples. For Scots pine, the only factor of importance was whether the samples consisted of heartwood or of sapwood. Annual ring width, density and origin had no significant effect on either fungal growth or moisture uptake. This observation held for both Norway spruce samples and Scots pine samples. An accelerated test was run in order to investigate Norway spruce sapwood and heartwood with respect to their differences in durability towards discolouring fungi and moisture uptake. The Mycologg method was used to accelerate fungal growth during a number of forced moisture cycles. The results showed that sapwood was much more sensitive to discolouring fungi than heartwood. Sapwood also recorded a higher average moisture content than heartwood. The differences that were observed between the types of samples were not due to annual ring width, density or origin. It was observed that Norway spruce sapwood samples and heartwood samples showed differences in liquid water permeability. This observation was made especially evident in a droplet absorption test. Water droplets were absorbed much faster on the sapwood samples in comparison with the heartwood samples. This higher affinity to water suggested that a sapwood surface would reach a higher moisture content than a heartwood surface. This observation provides a major explanation of why the sapwood samples showed poorer durability towards discolouring fungi in the Mycologg trials.

  • Det våldsamma mötets fenomenologi : - om hot och våld i psykiatrisk vård
  • 2004
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • The present study focuses on the phenomenology of the violent encounter, and is to be understood as the study of the violent encounter as a phenomenon, i.e. as experienced. The overall aim is to elucidate, analyse and describe violent encounters within psychiatric care as experienced by carers and patients. Moreover, the study aims at promoting the development of a phenomenological research approach in caring science in general and elucidating tacit caring knowledge in particular.The thesis includes three empirical studies and one methodological study. The research is guided by a phenomenological and lifeworld theoretical approach. Research data consist of narratives and qualitative interviews, as well as reenactment interviews with carers and patients. Data are analysed for meaning. The analysis and synthesis of meaning are aimed at openness and meaning sensitivity through a reflective attitude characterised by the intent to bridle the process of understanding. The goal of the analysis is to describe the general structure of the phenomenon and its meaning constituents.The result shows that violence and threat do not evolve in “naked” caring, characterised by encounters where carers are able to touch their patients at the same time as being touched, speaking both literally and figuratively. It is through “naked” caring and caring touch that the carers are able to reach the patients and to give undisguised invitations to genuine presence. The possibilities of touch rely on the carers’ capacity to be authentic and to genuinely wish well. Violence is on the contrary nourished by touch without caring intention, or non-touch, i.e. caring where the reciprocity of touching and being touched is missing between patients and caregivers.In the discussion, the different meanings of the violent encounter are related to the philosophy of Merleau-Ponty and Lévinas. The philosophical dimensions of touch are investigated and it is discussed how the “naked” encounter can be understood from a phenomenological ethical standpoint. The discussion focuses on the caregivers’ vulnerability and the high demands they are subjected to. It is also argued that a foundation of caring science is needed in caring practice in order to make possible a development of a caring attitude that prevents violence.

  • Medborgarskap som demokratins praktiska uttryck : - diskursiva konstruktioner av gymnasieskolans elever som medborgare
  • 2006
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Abstract Carlsson, Lena (2006). ). Medborgarskap som demokratins praktiska uttryck i skolan. Diskursiva konstruktioner av gymnasieelever som medborgare. Citizenship as the practical expression of democracy at school. Discursive constructions of upper secondary pupils as citizens. School and education have a specific status owing to their task to educate young citizens and further their development. It is thus possible to regard schools as a type of public sphere, where individual and private matters are transcended. According to the curriculum for the secondary school system, the professional school staff´s task is two-fold insofar as they should mediate both knowledge and democracy. In this doctoral thesis the focus is placed on how and by what means education can contribute to young members of society finding their place and coping with their roles as citizens in a democratic society. The overall aim of this thesis is to present a deeper interpretation of the meanings and consequences of teachers´ speech concerning upper secondary pupils as citizens. More specifically, the aim is to empirically problematise and theoretically reconstruct pedagogical discourses on citizenship as practical expressions of demoracy in the context of education. Two central terms, which are thus highlighted are democracy and citizenship. Both Durkheim and Dewey provide significant theoretical points of departure, which are drawn upon in this thesis. Bourdieu contributes with perspectives on the ideological role, which institutions of education play in legitimising already existing societal orders. Foucault poses questions about power and knowledge. Habermas’ emphasis is placed on the discursive rationality expressed in verbal communication, which serves as an overall perspective for this thesis. Thus, in terms of methodology language constitutes the most central tool. Analyses are made in three stages. Reforms and policy are supposed to have been created within a central discursive framework and are therefore examined by way of analytical perusal of a) post-war education policy texts and b) current national policy documents concerning the Business and Administration Programme in upper secondary education. The third stage involves analysis of c) eight conversations from the professional school staff’s discursive practice by applying critical discourse analysis as a methodological tool. Four separate discourses have evolved, each pointing to different perspectives on human beings, knowledge and society: a discursive perception which is directed towards traditional values, a second perception which has communication and democracy as its superior ideal, and yet another discourse is directed towards trade and industry while, finally, one more discourse which is mainly characterised by a protective attitude towards pupils. Finally, how these contradictory as well as concordant discourses dictate the conditions and frameworks for the sort of citizenship which is constructed and constituted in the pedagogical practice is discussed, and thus how school as a public sphere may be understood in a more profound way. Key words: democracy, citizenship, critical discourse analysis, discursive constructions, reforms, policy, communication.

  • Essays on Discrimination in Hiring
  • 2009
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This thesis consists of four self-contained essays on discrimination in hiring. Essay I (co-authored with Dan-Olof Rooth) present evidence of ethnic discrimination in the recruitment process by sending fictitious applications to real job openings. Applications with identical skills were randomly assigned Middle Eastern or Swedish-sounding names and applications with a Swedish name receive fifty percent more callbacks for an interview. We extend previous analyses by adding register and interview information on firms/recruiters to the experimental data. We find that male recruiters and workplaces with fewer than twenty employees less often call applications with a Middle Eastern name for an interview. Essay II extends previous field experiments that study ethnic discrimination in the labour market by comparing discrimination of first and second generation immigrants from the same ethnic group. Qualitatively identical resumes, belonging to first and second generation immigrants from the Middle East, were sent to employers in Sweden that had advertised for labour. The findings suggest, somewhat unexpectedly, that first and second generation immigrants have essentially the same probability of being invited to a job interview, which in turn is significantly lower than the probability of invitation to interview for natives. Accordingly, the factor leading to discrimination in employers responses appears to be ethnicity per se and not an applicant’s country of birth, foreign mother-tongue, and foreign education. Essay III (co-authored with Dan-Olof Rooth) utilizes the extensive media coverage that occurred when the data collection of essay I and II were only halfway finished. This informed the employers that their hiring practices were being monitored by such situation testing. These unique events and the data from the situation tests are utilized to perform a difference-in-differences analysis of whether discrimination decreased after the media coverage. The results reveal no sign that employers changed their hiring practices after they became aware of the risk of being included in such a situation test. The policy implication of this relates to the fact that EU countries vary in the extent to which they allow situation test results to constitute evidence of ethnic discrimination in court. Our results suggest that the detection risk alone is not sufficient, but must be combined with some penalty to become effective, if authorities wish to use situation testing as a discrimination prevention strategy. Essay IV studies whether sex discrimination is the cause of sex segregation in the Swedish labor market. The correspondence testing (CT) method was used, which entails two qualitatively identical applications, one with a female name and one with a male name, being sent to employers advertising for labor. The results show that, on average, females have a somewhat higher callback rate to interview in female-dominated occupations, while in male-dominated occupations there is no evidence of any difference. This suggests that the bulk of the sex segregation prevailing in the Swedish labor market cannot be explained by discrimination in hiring. Instead, the explanation is likely to be found on the supply side.

  • Creation of Industrial Competitiveness : CIC 2001-2004
  • 2005. - Acta Wexionensia
  • Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
    • The prerequisites for international industrial competitiveness are constantly changing. Technical developments, widespread internationalization, and deregulations bring about more establishments and different competitive situations. Furthermore, customer needs and demands vary. All these changes affect to a high degree individual companies, industries and the society as a whole. However, we do not know enough about what constitutes industrial competitiveness and underlying processes. Therefore this question is pertinent:  How is industrial competitiveness created in constantly changing international environmnets?Finding answers to this all-embracing question is, thus, the foundation for the research presented in this book. The first part of the book presents separate projects which focus on industrial competitiveness from an internal effectiveness perspective, while the second part consists of projects which penetrate the subject from a business perspective. The final part starts with a discussion on the overall findings, and ends with conclusions in relation to the question above and specifications of the need for further research.The outcome of this book contributes to theory on sources of industrial competitiveness in general. More specifically, frameworks are developed comprising concepts and models in crucial areas such as business strategy, core competence, industrial marketing, quality management, interorganizational relations and internal effectiveness. Companies may benefit from the results as it provides guidance and supportin the search for competitiveness, based on studies of high performing companies in different industries. The knowledge will also help in understanding crucial processes that effect economies and the society as a whole.

  • Etik och utmaning. : Om lärande av bemötande i professionsutbildning
  • 2003
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • During recent years there have been noticeable shortcomings in the human encounter of people seeking some form of health care in Sweden. This is something that affects professional education within ‘the welfare state’ and implies that human expectations, societal demands and questions about knowledge, basic values and competence have become pedagogically interesting. The basic aim of the dissertation is - to contribute to a practically, relevant and theoretical in-depth understanding of the learning and teaching of ethics in professional education. By taking nursing education as an example and focussing on the human encounter of the person seeking care, the dissertation aims - by analysis of the pedagogic practice and from a critical-theoretical perspective – to provide a foundation for such an understanding. The research perspective includes a social-philosophical point of departure with a focus on Mead’s interactional view of learning and Habermas’s critical theory of social communication. Methodologically an emphasis is placed on discourse analysis. The results demonstrate how the learning and teaching of ethics in human encounters can be understood as a question of communication of both knowledge and values. In the theoretical reconstruction that follows it is shown how pedagogic actions, learning and competence can be understood as communication of and in particular contextual discourses. The six discourses are: ‘the efficiency-related discourse’, ‘the expert-related discourse’, the ‘care-related discourse’, ‘the communicative-related discourse’, ‘the egocentric discourse’ and ‘the ethnocentric discourse’, all of which are mutually related to each other. The contextual discourses focus on different values. Those that are most conducive to creating pleasant human encounters are the communicative- and the care-related discourses, which also form the foundation for the pedagogic recommendation that makes up the concluding discussion of the dissertation. The recommendation concerns a pedagogical practice that affirms, pays attention to, safeguards and challenges and thus generates creativity, as well as the legitimacy of pluralism. To engage in stimulating pedagogical discussion means being committed, taking responsibility and practicing solidarity in the profession of education. Such a ‘deliberative pedagogy’ creates possibilities for people to develop solidarity of judgement in a society that increasingly demanding that. In conclusion, the recommendation for a new and challenging human encounter-ethical-pedagogy is intended to show that ‘ideals can be realistic’. Normative recommendations do not have to be abstract visions of the future, but can be looked upon as means of focussing on alternative actions, that despite the difficulties are possible to realise – here and now.

  • Fri att konkurrera, skyldig att producera : En ideologikritisk granskning av SAF 1902-1948
  • 2005
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • The object of my investigation is Svenska Arbetsgivareföreningen (SAF) (The Swedish Employer’s Association) and the concrete questions I wish to raise are: (i) How did SAF articulate their ideal of liberty during the period 1902-1948? (ii) How did they combine this ideal with the demands of an ascetic work ethic among the workers?My ambition with this investigation has been to spread some light on how SAF, one of the market’s most important actors in Sweden during the twentieth century, has combined an alleged strong belief in personal freedom with the demands of adjustment to specific virtues and how the proclaimed freedom has, in fact, been subject to a number of conditions. It would be fair to say that the survival of a market economy depends on a broad foundation of workers that in practice are not allowed to make use of the freedom that they are proclaimed to have in theory. The workers must not only be convinced to go to work but also to work efficiently. If this were not the case, then capitalism, built on competition, would collapse. This is congruent with the conclusions made in my investigation. SAF’s proclamations of freedom were indeed a freedom for the believers; for those who could take advantage of the competition. But for those who did not believe in the system or who did not feel that they could find themselves justice in it, SAF demanded a high moral standard. As a consequence of this we are confronted with the following paradox: Freedom for the rich, morality to the poor.

  • Multi-oriented Symplectic Geometry and the Extension of Path Intersection Indices
  • 2005
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Symplectic geometry can be traced back to Lagrange and his work on celestial mechanics and has since then been a very active field in mathematics, partly because of the applications it offers but also because of the beauty of the objects it deals with.I this thesis we begin by the simplest fact of symplectic geometry. We give the definition of a symplectic space and of the symplectic group, Sp(n). A symplectic space is the data of an even-dimensional space and of a form which satisfies a number of properties. Having done this we give a definition of the Lagrangian Grassmannian Lag(n) which consists of all n-dimensional subspaces of the symplectic space on which the symplectic form vanishes. We carefully study the topology of these spaces and their universal coverings.It is of great interest to know how the elements of the Lagrangian Grassmannian intersect each other. A lot of efforts have therefore been made to construct intersection indices for elements of Lag(n). They have gone under many names but have had a sole purpose, namely to give us a way to determine how these elements intersect. We show how these elements are constructed and extend the definition to paths of elements of Lag(n) and Sp(n). We end this thesis by extending the definition of an index defined by Conley and Zehnder bu using the properties of the Leray index. Their index plays a significant role in the theory of periodic Hamiltonian orbit.

  • Kön, lön och karriär : Sjuksköterskeyrkets omvandling under 1900-talet
  • 2004
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • In a Swedish context this thesis deals with male integration in the profession of nursing during the last 50 years of the twentieth century.I focus on four different topics.At first the pioneer era is discussed, that is in the beginning of the 50s, when men were allowed to enter the nursing profession and become nurses. Here I discuss on the Swedish Society of Nursings (Svensk Sjuksköterskeförening, SSF)) standpoint on the matter of men’s ability to participate in a sphere so closely connected with professional values as well as feminine values of caring and support.The second topic deals with the question of using the concept ‘sjuksköterska’ (nurse), in Sweden a feminine marked word, as a title for both men and women. The result of a long and keen debate is that a lot of imaginative titles were refused and that still today both women and men use the female title ‘sjuksköterska’. This might be one reason for men not seeking the profession of nursing.In the third place I look at the pecuniary result for nurses especially after 1986 when a new individual oriented wage determination was launched. The local investigation comprises four different clinics at the University hospital in Malmö (Universitetssjukhuset Malmö allmänna sjukshus, UMAS) and takes a special interest in earnings between male and female nurses. In countries with long experience of individual wage systems male nurses usually earn more than their female counterparts. The question I ask is if the same tendency is about to happen in Sweden.Finally, the possibilities of making a career in the profession of nursing is analyzed. The local investigation stresses that female nurses seem to prefer an administrative career in an increasing extent than men do. Male nurses, on the other hand, made union careers in the 70s and 80s and especially the post as ombudsman is popular. In the mid 90s the male appointment to union position is growing weaker probably connected to an increasing feminine consciousness among female nurses. Also the professionalisation process of the nurse corps is shortly examined.
