The thesis comprises four papers. The overall aim was to illuminate meanings of becoming and being burnt out respectively not becoming or being burnt out. The papers deal with two groups of healthcare personnel, one group on sick leave due to medically assessed burnout (n=20) and one group who showed no indications of burnout (n=20) from the same workplaces at psychiatric (n=7) and elderly (n=7) care units. A further aim was to describe personality traits and to elucidate perceptions of conscience (PCQ), stress of conscience (SCQ), moral sensitivity (MSQ-R), social support (SocIS) and resilience (RS) among the people in these two groups. Papers I and II are based on the text of narrative interviews interpreted using a phenomenological-hermeneutic method. Papers III and IV are based on data, pertaining to the same participants as in Papers I and II, derived from the following questionnaires; Cattell’s Sixteen Personality Factors Questionnaire (16PF) (III), ‘Perception of Conscience’ (PCQ), ‘Stress of Conscience’ (SCQ), ‘Moral Sensitivity Revised’ (MSQ-R), ‘Social Interactions Scale’ (SocIS) and ‘Resilience Scale’ (RS) (IV). Conventional statistical methods and Partial Least Square Regression (PLSR) were used to analyse the data (III, IV). In Paper I the aim was to illuminate meanings of becoming and being burnt out as narrated by healthcare personnel. The results show that meanings of becoming and being burnt out is to be torn between what one wants to manage and what one can actually manage. It is as if one’s ideals become more like demands for, regardless of the circumstances, one must be and show that one is capable and independent. It also means being dissatisfied with oneself for not living up to one’s own ideals as well as being disappointed in other people for not providing the confirmation one strives for. Feelings that one is a victim of circumstances emerge. Becoming and being burnt out leads to a futile struggle to live up to one’s ideals and when failing to unite one’s ideal picture with one’s reality one finally reaches an overwhelming feebleness. In Paper II the aim was to illuminate meanings of not becoming or being burnt out at workplaces where others developed burnout, as narrated by healthcare personnel. The results show that meanings of not becoming or being burnt out are to be rooted in an outlook on life which perceives its many-sidedness of prosperity, adversity, strength and weakness in oneself and others. An openness towards the circumstances of life emerges. Being able to judge the possibilities of influencing things, as well as being able to let go of injustice and look after oneself with a clear conscience are revealed as meanings of not becoming and being burnt out. In Paper III the aim was to describe personality traits among burnt out and non-burnt out healthcare personnel from the same workplaces. The results show, that the people in the burnt out group had lower scores regarding emotional stability and higher scores regarding anxiety than the people in the non-burnt out group but the results also showed a wide variation of personality traits within the groups. The most important indicators for belonging to the burnt out group were openness to changes and anxiety, and for belonging to the non-burnt out group, emotional stability, liveliness, privateness and tension. In Paper IV the aims were to elucidate perceptions of conscience, stress of conscience, moral sensitivity, social support and resilience among burnt out and non-burnt out healthcare personnel from the same workplaces. The results show that higher levels of stress of conscience and moral sensitivity, a perception of conscience as a burden, having to deaden one’s conscience in order to keep working in healthcare and perceiving a lack of support from those around them characterize the burnt out group. Those in the non-burnt out group are characterised by lower levels of stress of conscience, an out-look on life with a forbearing attitude, a perception of conscience as an asset, an ability to deal with one’s conscience in a constructive way and a perception of receiving support from those around them. The comprehensive understanding from the four papers (I-IV) is discussed in light of a theoretical framework derived from Emmy van Deurzens thoughts about the four life worlds: the natural world (the physical world), the public world (the social world), the private world (the psychological world) and the ideal world (the spiritual world). The result can be summarized in terms of the human condition in life and demonstrates the essential importance of reconciling the vita activa (the active life of labor, work and action), the vita contemplativa (thinking, willing and judging) and not least the vita regenerativa (rest and recovery) in order to avoid being burned out. / Samvetsstress i vården

The aim of this thesis was to investigate what an intervention comprising systematic discussion groups meant in the context of conflicts and cooperation between social care staff and nursing staff, over a period of 7–15 months. The intervention was carried out in four experimental dwellings in special types of housing for elderly and disabled people and in comparison with four similar reference dwellings. Results are based on 27 interviews prior to the intervention and 29 after. The interviewees were managers, registered nurses, enrolled nurses and care assistants and concerned their experiences regarding problematic situations that occurred in their everyday work. The questionnaires (before n=84 and after intervention n=93) used were: sense of coherence, job-satisfaction and burnout and were aimed at investigating staff experiences of working climate and the influence of the intervention. The issues were investigated both before and after the intervention. Observations were used to determine whether they could provide further knowledge about the intervention and thus extend our understanding of the marginal differences in the complementary studies. The phenomenological hermeneutic interpretation of the narratives in the interviews shows that the intervention was important to the experiences of being in problematic situations. The results before the intervention and in reference dwellings are equivalent and elucidate staff members' struggle to retain their self-esteem and to be confirmed by their colleagues. The experimental dwellings narratives show a change from rejecting to confirming communication among colleagues. Moreover, subtle changes are present which point to an emotional closeness where attempts have been made to understand colleagues' perspective and reactions where the residents are the central concern in the narratives. An analysis of the content of the interviews after intervention shows equivalent changes in experimental dwellings and reference dwellings. The analysis shows that the staff's view of problematic situations had been softened and that they viewed their colleagues as less of a hindrances. There were no mentions made of the previously indicated conflicts between social and nursing staff. The results also show that staff members are not afraid to stand by their own ideas of how they should act in various situations. The staff experience of the working climate was positive both before and after the intervention and no significant differences could be seen. What stands out from the observation study is that the groups have different cultures and thus different prerequisites for the intervention. In two of four groups the intervention seemed to give rise to positive meanings regarding the staffs´ understanding of each other, necessary for their successful cooperation, but when the groups are in the ”basic assumption phase” other additional strategies are probably also needed. The marginal differences shown in the other complementary studies can be understood in terms of two of the four groups not perceiving the intervention to any large extent. When the internal group processes are of great importance it is essential to pay attention to culture of the staff groups before the intervention is implemented.

The overall aim of the study is to understand and describe the phenomenon ‘atmosphere in care settings’ as experienced by patients, significant others and health care staff. The study consists of four papers, each of which illuminates various aspects of the phenomenon. Data consisted of observations and interviews with patients, significant others and staff (n=126) within a hospice, a geriatric, a medical and an oncology setting, and community care settings for older people. Narrative analysis, grounded theory, and phenomenological hermeneutics were used in a triangular fashion to analyse the data. The findings illuminate the phenomenon ‘atmosphere in care settings’ as being constituted by two interacting and interwoven dimensions: the physical environment and people’s doing and being in the environment. The physical environment is the first dimension, and five aspects were illuminated, namely the physical environment as a symbol; as containing symbols; as influencing interaction; as facilitating a shift of focus from oneself to the environment, and; as containing scents and sounds influencing experiences of at-homeness or alienation. People’s doing and being in the environment is the other dimension, and five aspects were illuminated, namely the experience (or absence of experience) of a welcoming; of seeing and being seen; of a willingness to serve; of a calm pace; and of safety. It was understood that people’s doing and being influences experiences of the physical environment and that the physical environment influences experiences of people’s doing and being. The comprehensive understanding illuminated that the phenomenon is not merely subtle qualities of the place for care, but an active part of care. Both the physical environment and peoples doing and being conveys messages of caring and uncaring. The atmosphere of a care setting can at best support experiences of at-homeness in relation to oneself, others and the surrounding world.

Avhandlingens övergripande syfte är att tolka och beskriva innebörder av stöd, utifrån att vara förälder till barn med funktionsnedsättning och att vara professionella stödjare. Datainsamling har skett i form av berättande intervjuer med 39 föräldrar (23 mödrar och 16 fäder) och 9 professionella (7 kvinnor, 2 män) från olika verksamheter. Samtliga intervjuer har analyserats med hjälp av fenomenologisk hermeneutisk metod. Innebörder av att vara förälder till barn med funktionsnedsättning (studie I) har tolkats som en medvetenhet om viktiga värden i livet. Barnet har ett inneboende värde som en unik person och föräldrarna strävar efter att göra sitt bästa för barnet. Denna strävan innebär att konfrontera oro, osäkerhet och rädsla i vården av barnet och andra personers nedvärdering av barnet. I föräldrarnas strävan att tillmötesgå barnets olika behov, ingår också att anpassa egna behov efter barnets. Den fördjupade förståelsen av studiens resultat är, att det handlar om en strävan att möjliggöra för barnet att leva ett gott liv. Innebörder av att få stöd av professionella (studie II) har tolkats som att föräldrar och barn blir bekräftade som värdefulla personer och att föräldrarna uppnår trygghet och kompetens i föräldraskapet och får ett hopp för barnets framtid. Erfarenheter av att inte få stöd, medför en kamp mot de professionella, för att kräva det stöd som föräldrarna anser att de och barnet behöver. Innebörder av att vara professionell stödjare (studie III), består av att ha personlig filosofi, som är integrerat i sättet att vara och handla som stödjare. Det innebär att vara trygg i hoppet om att det alltid går att göra något för att hjälpa, genom att söka unika lösningar i den aktuella situationen. Tillit till föräldrar som partners och att få deras tillit, samt att möjliggöra för föräldrarna att uppnå kompetens och trygghet i vården av sina barn är andra innebörder. Detta har tolkats som en frihet från att vara bunden av byråkrati och prestige och en möjlighet att vara äkta, följa sin filosofi och att vara i samklang med barn och föräldrar. Innebörder av informellt stöd (studie IV) har tolkats som en livsberikande gemenskap, där barnet, innefattas i kärleksfulla relationer med närstående och har en naturlig plats i samhället. Att som föräldrar kunna dela glädje, oro och sorg med andra personer och att få möjlighet att uppleva lättnad och spontanitet i det dagliga livet, är andra innebörder av informellt stöd. Helhetsförståelsen av de fyra studierna är, att stöd av professionella i sin tur är ett stöd i föräldrars etiska förpliktelse i deras strävan att möjliggöra för barnet att leva ett gott liv. Informellt stöd betyder att föräldrar och barn är inneslutna i trofasta och berikande relationer med andra. / The overarching aim of this thesis is to interpret and describe the meanings of support for parents from the context of being a parent of a child with disability. The data collection is based on narrative interviews with 39 parents (23 mothers and 16 fathers) and nine professionals (seven women and two men) from various areas in the health care system and local authority. A phenomenological hermeneutic method guided the text analyses. The meanings of being a parent of a child affected by disability (study I) have been interpreted as awareness about important values in life. The child has an intrinsic value as a unique person and the parents are striving to do their best for their child. This striving means confronting worries, unsafeness and fear in the care of the child and confronting other persons’ devaluation of the child. Adjusting the parents’ own needs to those of the child and orchestrating the child’s various needs are other meanings. The deepened understanding of the result of the study is that the parents are striving to enable the child a good life. Being supported by professionals (study II) means experiences of the child and oneself as being confirmed as valuable persons. Moreover, it enables parents to gain confidence and competence in their parenthood and hope for the child’s future. Experiences of lack of support give rise to a struggle against the professionals, aimed at getting the support the parents regard as necessary for their own and their child’s needs. The meanings of being a supporter (study III) were interpreted as being and acting according to a personal philosophy, which is integrated in the professional task, and believing that it is always possible to help by searching for unique solutions in the current situation. Trusting the parents as partners and enabling the parents to gain competence and confidence in the care of their children are further meanings. The deepened understanding of being a professional supporter is to be in tune with one’s philosophy and the child’s and parents’ needs. The meanings of informal support (study IV) were interpreted as experiences of being involved in true relationships with other persons. This enables the child and the parents to be in a life enriching togetherness. The interpreted whole of the studies is that being a parent of a child affected by disability means to strive for the fulfilment of the ethical obligation to enable the child to have a good life. To be supported by professionals means receiving help to fulfil the ethical obligation. Being a professional supporter means to be and act in accordance to the unique child and parent and the present situation. Informal support means to be involved in a natural human togetherness.

The present study is an existential phenomenological investigation of the experiences of maternal guilt of five first-time mothers with infant children. Maternal guilt is a powerful, pervasive, and complex phenomenon that effects and is experienced by mothers in different ways. This research explores the experiences of these five mothers in feeling guilt related to being a mother and, using an adapted research methodology utilizing Focusing Technique (Gendlin, 1981), their embodied reflections about a particular memory of feeling maternal guilt. This study utilizes procedures explicated by Colaizzi (1978), Giorgi & Giorgi (2003), Todres (2007), von Eckartsberg (1998), Walsh (1995; 2004) and Wertz (1984). All participants provided data via a written account of a particular memory of feeling a sense of guilt related to being a mother, an individual interview which incorporated a modified Focusing component, and written and verbal feedback related to the write-up of the provisional thematic analysis of the interview. The interpreted analyses of the five interviews indicate seven formulated themes; physical and emotional connection to their babies, intense feelings of responsibility, feelings of being divided, multi-dimensionality of guilt with other emotions, pre-verbal miscommunication, anxiety over the unknown in the beginning, and social expectations and comparisons. The findings suggest that the process of embodied reflection regarding a new mother's emotional experiences of guilt can foster important awareness for how she can care for her own and her child's needs. Relationships between contemporary cultural discourses on motherhood and philosophical interpretations of guilt are discussed. Implications for creating networks of support and community for new parents are also explored. / McAnulty College and Graduate School of Liberal Arts; / Clinical Psychology / PhD; / Dissertation;

A detailed multi-zone thermodynamic simulation has been developed for the direct-injection (DI) diesel engine combustion process. For the purpose of predicting heterogeneous type combustion systems, the model explores the formation of pre-ignition radicals, start of combustion, and eventual heat release. These mechanisms are described based on the current understanding and knowledge of the diesel engine combustion acquired through advanced laser-based diagnostics. Six zones are developed to take into account the surrounding bulk gas, liquid- and vapor-phase fuel, pre-ignition mixing, fuel-rich combustion products as well as the diffusion flame combustion products. A three-step phenomenological soot model and a nitric oxide emission model are applied based on where and when each of these reactions mainly occurs within the diesel fuel jet evolution process. The simulation is completed for a 4.5 liter, inline four-cylinder diesel engine for a range of operating conditions. Specifically, the engine possesses a compression ratio of 16.6, and has a bore and stroke of 106 and 127 mm. The results suggest that the simulation is able to accurately reproduce the fuel jet evolution and heat release process for conventional diesel engine combustion conditions. The soot and nitric oxide models are able to qualitatively predict the effects of various engine parameters on the engine-out emissions. In particular, the detailed thermodynamics and characteristics with respect to the combustion and emission formation processes are investigated for different engine speed/loads, injection pressures and timings, and EGR levels. The local thermodynamic properties and energy, mass distributions obtained from the simulation offer some fundamental insights into heterogeneous type combustion systems. The current work provides opportunities to better study and understand the diesel engine combustion and emission formation mechanisms for conventional diesel engine combustion modes. The flexible, low computational cost features of this simulation result in a convenient tool for conducting parametric studies, and benefits for engine control and diagnostics.

The purpose of this study was to describe experiences in daily social life of parents of children with psychotic illness. Five parents with long-term experience of psychotic illness have been interviewed. The frame of reference in emotion theories of Thomas Scheff and Randall Collins have been used to analyze the results. The study is qualitative and has a phenomenological approach to shed lights of meanings in daily social life. The following meanings was found: Openness with certain reservation shows that honesty is important for the feeling of solidarity, Social expectations in daily life describes the parents´own expectations as well as expectations from others. In The important confirmation the findings show that the parents´need understanding for the family situation, and the findings also show the importance of support for the family and the acceptance of the psychotic illness.

Science communication, as a multidisciplinary field, serves to transfer scientific information to individuals to promote interest and awareness in science. This process resembles science education. Rooted in science education and science communication studies, this study examines the 4th and 5th grade students` usage of prominent science information sources (SIS), the features of these sources, and their effective and ineffective uses and processes in communicating science to students. Guided by situated learning and uses and gratifications (U&amp / G) theories, this study is a phenomenological qualitative inquiry. Data were gathered through approximately 64 hours of classroom observations / focus group and individual interviews from four elementary schools (two public, two private schools) in Ankara, T&uuml / rkiye. Focus group interviews were conducted with 47 students, and individual interviews were carried out with 17 teachers and 10 parents. The data were analyzed manually and MAXQDA software respectively. The results revealed that students used various SIS in school-based and beyond contexts to satisfy their cognitive, affective, personal, and social integrative needs. They used SIS for (a) science courses, (b) homework/project assignments, (c) exam/test preparations, and (d) individual science related research. Moreover, the results indicated that comprehensible, enjoyable, entertaining, interesting, credible, brief, updated, and visual aspects of content and content presentation of SIS were among the key drivers affecting students` use of SIS. The results revealed that accessibility of SIS was an important variable in students` use of these sources. Results further shed light on the connection between science education and science communication in terms of promoting science learning.

Shape memory alloys (SMAs) are metallic materials, which have two main stable crystalline phases: austenite, a high temperature phase and martensite, a low temperature phase. Austenite and martensite each have unique physical and mechanical properties, and transformation between these phases enables two effects known as the shape memory effect (SME) and superelasticity. When a material that displays the SME is plastically deformed at low temperature, a heat input will cause the SMA to return to its original shape before the deformation. At higher temperatures, the material displays an effect called superelasticity, where strains of up to 10% are recoverable. These characteristics of SMA allow for significant amounts of strain recovery, and enable the design of SMA actuators. The temperature in an SMA actuator is generally controlled by resistive heating, also know as joule heating, and the strain recovery capabilities are used to do work on a load, thereby creating an electro-mechanical actuator. SMA actuators have attractive properties such as high energy density, smooth and silent actuation, reduced part counts compared to traditional alternatives, and scalability down to the micromechanical level. The phase transformation in SMA actuators, however, is highly non-linear. Therefore, the use of SMA as actuators, for example in positioning systems, benefits from the development of good models to predict and control the materials. The goals of this work are to develop a model suitable for real-time implementation, and that reproduces the observed behaviour of SMA actuators. The model is then inverted and used to develop a model-based controller, used in conjunction with traditional PID control to improve the precision and robustness of SMA actuators. The modelling portion of this work consists of the development of a phenomenological SMA model. The forward model is split into three blocks: a heating block, a phase kinetics block and a mechanical block. Since joule heating is commonly used in SMA actuators to bring about an increase in temperature, the heating block presents equations to convert a current input into the temperature of the wire. The phase kinetics block equations convert the calculated temperature and applied stress to the fraction of martensite present in the SMA. Finally, the mechanical model calculates the strain in the material from the martensite fraction and the applied stress. Once the model equations are presented, experimental verification tests are shown to compare physical SMA behaviour with that predicted by the model. Each of the blocks of the forward model are then inverted in order to be used as a feedforward linearizing controller. The control section of this thesis deals with the response of two common types of SMA actuators: a constant force SMA actuator and a spring-biased SMA actuator. The response of the system to step and sinusoidal signals with period of 5 seconds is investigated using two types of controllers: a traditional PI controller and the inverse-model controller in feedforward with a PI controller in feedback. Additionally, the robustness of the system is investigated through the response of the system to transient and sinusoidal stress disturbances. The disturbance rejection is investigated on a constant force actuator both with and without the presence of a force sensor.

Certain contemporary philosophers (e.g. Dainton, 2008; Strawson, 1999; Foster, 2008) have thought that the first-person, qualitative aspect of conscious experience should be taken seriously when it comes to our thinking about personal identity through time. These philosophers have thus argued that experiential continuity is essential to a person’s ability to persist identically through time. This is what I will call ‘the phenomenological theory’. In this thesis I describe the phenomenological theory and then discuss three problems that have plagued the history of this theory: the bridge problem, the token problem, and the ontological problem. I will argue that a recent version of the phenomenological theory proposed by Barry Dainton and Timothy Bayne (2005) provides satisfactory answers to two of these problems, but not the third. I will conclude this thesis by proposing a superior version of the phenomenological theory—one that can handle all three problems.
