Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis is about people engaged in project-based work, a work context that is becoming increasingly common since more and more firms are relying on project-based forms of organization. More specifically, the thesis deals with a specific condition arising in projectbased work, namely that of ‘work liminality’. The thesis aims at enhancing the understanding of work liminality and of individuals who hold liminal positions. More specifically it aims to investigate how liminality could be understood in the context of project-based work, what practices project workers rely on to deal with work liminality. The thesis also deals with how project workers perceive their work and what competencies they have in relation to their perceptions.The concept of liminality stems from anthropology, in which it denotes a transition phase from one social position to another, e.g. the transition from being a boy to becoming a man. The notion of liminality has been brought into organization studies to depict a position of ambiguous belonging and temporality. It has been used to describe the position for e.g. contingent workers, who simultaneously work and affiliate with different firms and work in temporary assignments. This thesis, however, focuses on liminality in project-based work, and it introduces the notion of ‘work liminality’ to describe a specific work situation with inherent organizational ambiguity and transiency. Project workers hold a liminal position since they simultaneously belong to a line division and one or several projects, and moreover, projects are time-limited, and can be viewed as a transition for the individual, who continuously moves from one project to the next. In that respect, project-based work constitutes a particularly interesting empirical context for the study of work liminality, and compared to other liminality situations, this context has received relatively little scholarly attention in previous research.The study presented in this thesis focuses on a particular kind of mobile project worker, namely technical consultants. These are workers who move from project to project, often across client organizations, on a continuous basis. They thus work under liminal conditions, both in terms of having several organizational belongings, and in terms of continuously switching assignments. The thesis is based on altogether 37 interviews, 13 narrative weekly diaries written under a period of three months and a number of workshops and both formal and informal meetings, mainly with technical consultants but also with managers at one of Scandinavia’s leading technical consultancy firms (which is anonymous in the thesis).Based on how liminality has been used in previous organization studies it is rather unclear what it implies, the more objective liminal position and how this is perceived by individuals who hold it, is not clearly separated in these studies. This thesis therefore suggests the analytical distinction between on the one hand ‘work liminality’, as a work situation in which the individual holds a position that is characterized by organizational ambiguity and transiency, and on the other hand how work liminality is experienced by people who engage in it. Results from this study indicate that mobile project workers experience work liminality largely in two types of situations, one primarily technical and the other foremost social. Moreover it indicates that individuals approach these situations, here denoted as social and technical liminality, either actively or passively. This leads to the proposition that the mobile project workers rely on predominantly four different ‘liminality practices’ to deal with social and technical liminality, namely ‘reputation reliance’, ‘role carving’, ‘relaxation’ and ‘redefinition’. Furthermore, an interpretative approach is used to study mobile project workers’ ‘liminality competence’. The empirical investigation shows three different conceptions of work held by the mobile project workers: ‘work as assignment handling’, ‘work as a learning platform’ and ‘work as knowledge transfer’, which are linked to three levels of liminality competence, respectively. Liminality competence concerns how the mobile project workers deal with working in a position of work liminality, while liminality practices rather concerns how the mobile project workers deal with specific situations that arises due to work liminality.

- Histopathology of testicular tissue is considered to be the most sensitive tool to detect adverse effects on male reproduction. When assessing tissue damage, seminiferous epithelium needs to be classified into different stages to detect certain cell damages; but stage identification is a demanding task. The authors present a method to identify the 12 stages in mink testicular tissue. The staging system uses Gata-4 immunohistochemistry to visualize acrosome development and proved to be both intraobserver-reproducible and interobserver-reproducible with a substantial agreement of 83.6% (kappa=0.81) and 70.5% (kappa=0.67), respectively. To further advance and objectify this method, they present a computerized staging system that identifies these 12 stages. This program has an agreement of 52.8% (kappa 0.47) with the consensus staging by 2 investigators. The authors propose a pooling of the stages into 5 groups based on morphology, stage transition, and toxicologically important endpoints. The computerized program then reached a substantial agreement of 76.7% (kappa=0.69). The computerized staging tool uses local ternary patterns to describe the texture of the tubules and a support vector machine classifier to learn which textures correspond to which stages. The results have the potential to modernize the tedious staging process required in toxicological evaluation of testicular tissue, especially if combined with whole-slide imaging and automated tubular segmentation.

- BACKGROUND: Exposure to xenoestrogens in humans and animals has gained increasing attention due to the effects of these compounds on reproduction. The present study was undertaken to investigate the influence of low-dose dietary phytoestrogen exposure, i.e. a mixture of genistein, daidzein, biochanin A and formononetin, on the establishment of testosterone production during puberty in male goat kids. METHODS: Goat kids at the age of 3 months received either a standard diet or a diet supplemented with phytoestrogens (3-4 mg/kg/day) for approximately 3 months. Plasma testosterone and total and free triiodothyronine (T3) concentrations were determined weekly. Testicular levels of testosterone and cAMP were measured at the end of the experiment. Repeated measurement analysis of variance using the MIXED procedure on the generated averages, according to the Statistical Analysis System program package (Release 6.12, 1996, SAS Institute Inc., Cary, NC, USA) was carried out. RESULTS: No significant difference in plasma testosterone concentration between the groups was detected during the first 7 weeks. However, at the age of 5 months (i.e. October 1, week 8) phytoestrogen-treated animals showed significantly higher testosterone concentrations than control animals (37.5 nmol/l vs 19.1 nmol/l). This elevation was preceded by a rise in plasma total T3 that occurred on September 17 (week 6). A slightly higher concentration of free T3 was detected in the phytoestrogen group at the same time point, but it was not until October 8 and 15 (week 9 and 10) that a significant difference was found between the groups. At the termination of the experiment, testicular cAMP levels were significantly lower in goats fed a phytoestrogen-supplemented diet. Phytoestrogen-fed animals also had lower plasma and testicular testosterone concentrations, but these differences were not statistically significant. CONCLUSION: Our findings suggest that phytoestrogens can stimulate testosterone synthesis during puberty in male goats by increasing the secretion of T3; a hormone known to stimulate Leydig cell steroidogenesis. It is possible that feedback signalling underlies the tendency towards decreased steroid production at the end of the experiment.

- Background: The number of homeless people in Sweden amounts to approximately 34 000. Of those about 4500 live in streets or shelters. The mortality rate among homeless people outnumbers other groups in the society. Often they have severe, multiple mental and physical illnesses, drug abuse and a variety of complex care needs, including palliative. From an international perspective, research related to care for homeless people with severe illness and complex care needs is very sparse (no Swedish studies have been identified). Among the few that have been found, challenges related to the homeless situation and the illness panorama are reported. From the perspective of the homeless persons themselves, studies report stigmatisation, lack of respect and competence among health-care professionals, and insufficient organisation of health care.Aim: The aim of this study is to explore the development of experience-based knowledge among health care professionals and social workers in a unique setting, in which advanced inpatient health -and social care, including palliative care is provided to homeless people.Methods: In this on-going qualitative case-study, clinically relevant and applicable knowledge is focused. Repeated focus group discussions and coupled thematic interviews were performed with staff (physicians, social workers, mental carers, nurses). Analysis is performed with an interpretive descriptive method.Results and implication: The results, which are currently being processed, will present staffs’ experiences of identification and assessment of individual care needs, specific knowledge development and requirement in relation to palliative care and homelessness, and challenges, obstacles and opportunities for meeting the needs of severely ill and dying homeless people. The results will provide knowledge of importance for the development of care for severely ill homeless persons.

- Despite high frequencies of multiple, life-limiting conditions relating to palliative care needs, people who are homeless are one of the most underserved and rarely encountered groups in palliative care settings. Instead, they often die in care places where palliative competence is not available. In this qualitative single-case study, we explored the conditions and practices of palliative care from the perspective of staff at a Swedish support home for homeless people. Interpretive description guided the research process, and data were generated from repeated reflective conversations with staff in groups, individually, and in pairs. The findings disclose a person-centered approach to palliative care, grounded in the understanding of the person’s health/illness and health literacy, and how this is related to and determinant on life as a homeless individual. Four patterns shape this approach: building trustful and family-like relationships, re-dignifying the person, re-considering communication about illness and dying, and re-defining flexible and pragmatic care solutions.
