Promoting health in adolescents : preventing the use of tobacco
- 2009

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- There is a robust evidence base for the negative health effects from smoking. Smoking is linked to severe morbidity and to mortality, and kills up to half of its regular users. Tobacco use and production also bring other negative consequences such as economic loss for countries, poverty for individuals, child labour, deforestation and other environmental problems in tobacco growing countries. A combination of comprehensive interventions at different levels is needed to curb the tobacco epidemic. Tobacco control strategies at national levels in the western world often include components of information/education, taxation, legislative measures and influencing public opinion. Two approaches have dominated at the meso and micro levels: cessation support for tobacco users and prevention activities to support young people refraining from tobacco use. Smoking uptake is a complex process that includes factors at the societal level as well as social and individual characteristics. At national level, taxation and legislation can contribute to a societal norm opposing tobacco and creating a context for primary prevention aimed at tobacco free youth. There is no magic bullet in primary prevention. At the meso and micro levels, a continued development of knowledge on the underlying mechanisms and primary prevention methods is essential to prevent young people from starting to use tobacco. The overall aim of this thesis was to gain knowledge about factors that influence young people’s use of tobacco and of preventive mechanisms. The specific aims included to study the relation between Tobacco Free Duo, an intervention program targeting youth in Västerbotten County, and tobacco use prevalence. A specific interest was to explore the role adults can play in supporting young people to refrain from tobacco use. The thesis is based on four studies with three separate sets of data, two were quantitative and one was qualitative. The studies were conducted among adolescents (aged 13-15 yr) in Västerbotten County and on national level in Sweden (aged 13, 15 and 17 yr). Tobacco Free Duo is a school-based community intervention that started in 1993. An essential component of the intervention was to involve adults in supporting adolescents to stay tobacco free. Results showed decreased smoking in adolescents among both boys and girls in the intervention area during the study period of seven years. There was no change in a national reference group during the same time period. A bonus effect was a decrease in adult tobacco use in the intervention area. One out of four adults who supported a young person taking part in the intervention stopped using tobacco. In a qualitative assessment of young smokers, starting to smoke was described as a means of gaining control of their feelings and their situation during early adolescence. They expected adults to intervene against their smoking and claimed that close relations with caring adults could be a reason for smoking less or trying to quit smoking. In a quantitative study that used three decades of national data, over time adolescents became more positive toward parental action on children’s smoking. The adolescents strongly supported the idea of parental action, regardless of whether or not they themselves smoked. Adolescents preferred that actions from parents were dissuading their children from smoking, not smoking themselves, and not allowing their children to smoke at home. These results suggest that the Tobacco Free Duo program contributed to a reduction in adolescent smoking among both boys and girls. Using a multi-faceted intervention that includes an adolescent-adult partnership can decrease adolescent smoking uptake. Engaging adults as partners in tobacco prevention interventions that target adolescents has an important tobacco reducing bonus effect in the adults. The intervention has proven sustainable within communities. A growing majority of adolescents support parental interventions to help them refrain from tobacco. The findings dismiss the notion that adolescents ignore or even disdain parental practices concerning tobacco. A common and consequent norm against tobacco from both schools and parents using a supportive attitude can prevent tobacco use in young people.

Barn i rättens gränsland. : Om barnperspektiv vid prövning om uppehållstillstånd.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this study is to highlight problems regarding the status of children in determining the granting of residence permits. Central to the study are the rules contained in the Swedish Aliens Act (2005:716) about hearing children in the course of proceedings and the child’s best interests. The rules are based on Articles 3 and 12 respectively, in the United Nations Convention on the Rights of the Child (CRC). They were introduced into the Swedish legislation in 1997, after an intense debate questioning whether Sweden was meeting its obligations under the Convention. The application in aliens matters has, however, continued to be criticized after the revision of 1997, especially in matters concerning children. In 2006 a new Aliens Act came into force, involving a shift in the handling of such matters from administrative authorities and the Government to a system where appeals are tried in administrative courts. The legislation also involves comprehensive changes concerning the material legislation. The question has been raised, however, as to whether these changes have had any vital impact concerning the general construction of the material regulation. The apparent gap between the legislator’s intentions and the application of the law raises questions about the limitations of law and how the spirit and intentions of the CRC have been implemented in the Aliens Act, and, in view of this, the limits of law. The study involves an analysis of the fundamental premises that the legislation and application rest on, the general provisions of the proceedings and the technical formulation and also the material content of these rules. There is also an analysis of the impact and function of the legislation in practical applications. The conclusion is that the legislation allows extensive scope for assessing the circumstances in each case. This is the case, particularly in matters concerning children. Nevertheless, in practical applications, children often become irrelevant; children are simply not the real focus of the laws that affect them. Key words: Children’s rights, residence permit, asylum, immigration, equality, feminist perspectives. Eva Nilsson, Juridiska institutionen, Umeå universitet, 901 87 Umeå.

Efter kärnfamiljen : familjepraktiker efter skilsmässa
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This dissertation is about post-divorce families. The central question is how family is constructed after divorce. The aim is to study how family relationships are negotiated, transformed and reproduced after the separation. The research is based on 24 in-depth interviews with twelve young adults, between the ages of 21 and 29, with divorced parents. Their narratives about their families are analysed using a theoretical framework inspired by the individualization theories (Beck & Beck-Gernsheim 2001; Giddens 1997, 1995) and the doing family perspective (Morgan 1996; Silva & Smart 1999a), especially focusing on the concepts of negotiation and family practices. More specific questions raised in the dissertation are how are family boundaries drawn by the young adults? How do the interviewees understand the new organization of their families, which has been renegotiated after the separation? What perception of motherhood and fatherhood can be found in the narratives? And, finally, to what extent are family relationships after divorce negotiated in the way that the individualization theories claim?The results show a quite complex picture of family life after divorce. While both parents are often described as participating parents, the family practices after divorce appear clearly gendered. The mother’s involvement in taking care of the child seems not to be negotiable in the same way as the father’s. Hence, motherhood appears natural and taken for granted to a much greater extent than fatherhood. The negotiations between the parents after divorce can be of both an explicit and implicit character according to the narratives, but yet another kind of negotiation are the indirect negotiations. In these negotiations, the child is used as a go-between or carrier, a position that seems to limit their own possibility to participate in the decision making. Another aspect that seems to diminish children’s participation is the principle of loyalty to both their biological parents. The results also show that the children’s living arrangements after divorce are characterized by changes and renegotiations rather than being permanent. The parents’ new partners are described in different ways in the narratives, however, they are often seen as turning points that have a major influence on the family relationships. The nuclear family as a normative ideal is present in all the interviews but in different ways. While some express an explicit critique of it, others regard it as something that they want for themselves in the future. What constitutes a family according to the narratives? Firstly, blood ties and formal relationships are pointed out. Secondly, the feeling of solidarity and closeness is viewed perhaps as the most evident element of family life. This feeling can be created by open communication as well as by spending time together on a regular basis. Thirdly, growing up together and/or sharing everyday life practices are also considered as vital to develop and maintain close family ties. This means that the family boundaries after divorce are renegotiated over time rather than permanent. These negotiations take place in a certain context, where gender norms, earlier experiences and other social relationships play an important role.

La formation agentive en français : les composés [VN/A/Adv/P]N/A et les dérivés V-ant, V-eur et V-oir(e)
- 2008

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This study addresses the French morphological construction [VN/A/Adv/P]N/A. The main objectives are to posit a single rule for its formation and to question the implications of the agent polysemy. The theoretical framework is lexeme-based morphology, which adheres to weak lexicalism.The first part of our analysis is qualitative and concerns the availability aspect of productivity. The method is introspective. The internal semantic patterns of the French construction are examined. Our results give evidence for the claim that a single morphological construction rule, [VN/A/Adv/P]N/A, is responsible for the cases where the first constituent is a verb stem, and the second constituent may correspond to an internal argument, an external argument or a semantic adjunct. All cases manifest the same patterns, which are related to the denotative meanings included in the agent polysemy: Agent, Instrument, Locative, Action, Result and Cause. Our contrastive analysis shows that the same patterns are found in the four Swedish agentive formations, [N/A/Adv/PV-are]N, [N/A/Adv/PV]N, [N/A/Adv/PV-a]N and [VN]N, which correspond to the French [VN/A/Adv/P]N/A construction and which also contain a verbal constituent and its internal or external argument, or an adjunct.The second part of our analysis is quantitative and concerns the profitability aspect of productivity. The method is inductive. The aim is to explore the polysemy of agent and its assumed hierarchical structure, in synchrony and diachrony. Four French agentive formations, [VN/A/Adv/P]N/A compounds and V-ant, V-eur and V-oir(e) derivations, are included in order to examine semantic competition and blocking effects. Our results give evidence for the existence of an agent polysemy but deny that it has a hierarchical structure valid for every agentive formation. The meanings in the agent polysemy are more or less profitable according to formation type: blocking effects could explain this behaviour.

Creating customer value in commercial experiences
- 2009
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- There is a type of business offering gaining much attention, both in the media and in financial figures, which provides the customer with something extra, something to be remembered. This offering is a commercial experience. It is claimed that commercial experiences are different from traditional industry and mass-production and even separated from goods and services. The possibility of creating something extraordinary in order to gain profit is of increasing interest in today’s business world. Consumers are seeking for experiences to reach a higher level of personal growth, an experience that create personal identity and lead to long-lasting memories. This is something an increasing amount of consumers are willing to pay money for - the commercial experience market. The purpose of this thesis is to contribute knowledge about and a deeper understanding of commercial experiences, both in general and especially with regard to how customer value is created. The focus of the research was also to strengthen and support organizations that offer commercial experiences. In order to fulfill the purpose, two case studies were conducted with different focal points. The first aimed to find best practice and explore excellent ways of working when providing commercial experiences. The second study aimed to identify the needs for improvement to strengthen organizations offering commercial experiences. According to my findings, there seems to be several distinctions between commercial experiences and goods and services. These include; the level of price, the time spent by the customer, the customer affect as strongly emotional and maybe most importantly, the finding that commercial experiences create a higher level of customer value than goods and services. All this proves that the commercial experience is to be considered an offering on its own, a refined customer offer of higher value. Since commercial experiences are said to engage customers in an inherently memorable way, reaching a higher level of customer value than goods and services, is seen as a critical factor. Understanding what the customer really wants, needs and what builds customer value when offering commercial experiences then become particularly important as drivers of success. When studying a particular organization for best practice, several similarities between providing commercial experiences and working according to the core values of TQM were found and established as a factor of business excellence. Further when it comes to providing commercial experiences storytelling, theming and a creative environment stood out as additional factors of business excellence. Moreover, selecting the right co-workers based on their values rather than merely their skills and academic qualifications was seen as an important factor of success. The co-worker is often the co-creator of the experience together with the customer and therefore has an important part to play in the organization. Creating a corporate culture with co-workers sharing the values is seen as essential in order to run a successful business. It appears that any type of organization can provide an experience for the customer, the key is adding on the extra value to reach the level of attractive quality. The commercial experience is described as deeply affecting both the feelings and senses of the customer, resulting in new memories; it is a memorable event the customer is willing to pay for. The commercial experience contains elements of engagement, personal relevance, novelty, surprise and learning and is not limited to certain types of businesses. The fact that this is an area of increasing business interest but as yet a poorly explored one indicates that there is a need to develop improved ways of working, tools and methods, tailor-made for providing commercial experiences. Improved tools for identifying customer expectations and measuring customer satisfaction are clearly needed, especially since this is a growing industry that cannot be ignored. Welcome to further explore the experience economy where new memories are so highly valued that people are prepared to pay for them!

Leukocyte responses to pathogens : integrins, membrane rafts and nitric oxide
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- During microbial invasion, leukocytes of the innate immunity are rapidly recruited to the site of infection where they internalize (phagocytose), kill and digest the invaders. To aid this process, leukocytes express surface receptors such as Toll-like receptors, β2-integrins and Fc-receptors. The β2-integrins are also used for attachment to the extracellular matrix and are important for migration. When pro- vs. anti-inflammatory regulation of β2-integrins was investigated, it was found that chemotactic factors modulate neutrophil adhesion through altered affinity and/or avidity of β2-integrins. A bacteria-derived chemoattractant evoked a large increase in affinity as well as in mobility and clustering, while an early, host-derived chemotactic factor induced increased clustering and surface mobility, but only a slight increase in affinity. Anti-inflammatory lipoxin affected β2-integrin avidity, but not affinity.The leukocyte membrane is composed of lipids and proteins, which are inhomogeneously distributed. Specific domains in the membrane, membrane rafts, are enriched in signaling proteins and receptors. It was found that lipophosphoglycan (LPG) a virulence factor and membrane component of the parasite Leishmania donovani, accumulated in macrophage rafts during infection, inhibited PKCα translocation to the membrane and halted phagosomal maturation. Membrane rafts were instrumental for LPG to exert its effect. We further showed that nitric oxide (NO) rescued phagosomal maturation halted by Leishmania donovani parasites, possibly through effects on actin dynamics. NO did not affect parasite virulence per se. Moreover, lipoarabinomannan (LAM), a virulence factor on Mycobacterium tuberculosis (Mtb) bacteria, also inserted itself into macrophage membrane rafts. LAM from a less virulent strain (PILAM) was less efficiently inserted. Insertion could to some extent be inhibited by phosphatidylinositol mannoside (PIM), another structural molecule from Mtb. LAM did not activate the p38 MAPK signaling pathway nor did LAM interfere with TLR 2 or 4 signaling. In neutrophil leukocytes we observed a simultaneous, calciumdependent up-regulation of membrane rafts and secretion of azurophilic granules at the site of phagocytosis. Rafts were also found in the phagosome membrane. Wild type Streptococcus pyogenes bacteria, which can survive phagocytosis, modulated raft delivery.
