Limit-setting in publicly funded healthcare is unavoidable, and increasingly important in the governance and management of the demand for health services. The work of limit-setting takes place in the organising of the provision of health services, where various health workers (professionals, administrators, unit managers, politicians) collectively exercise their skills. Limit-setting often creates tensions which impose the quest for legitimacy; it involves norms and values which are related to the interests of the health workers, and moreover to society at large. In that sense, limit-setting is related to internal processes of legitimacy within the healthcare organisation, i.e. internal legitimacy, and external processes of legitimacy where citizens are legitimating the activities in the healthcare organisation, i.e. external legitimacy. The purpose of this thesis was to discover, and increase the understanding of the dilemma associated with sustaining, generating and designing internal legitimacy, when working with a policy of limit-setting in healthcare, in relation to the provision of Assistive Technologies (AT). It has explored what health workers do when they are working with a policy, and in particular how they work out what they should be doing. Finally the role of mediating institutions in supporting and designing internal legitimacy, was explored in the thesis. Following a case-study design and a qualitative approach, where fifty-seven semi-structured open-ended interviews were conducted, data allowed the exploration of internal legitimacy in a context of complex interaction and construction of policy work in two Swedish county councils. This research produced a number of key findings; in an environment of finite resources health workers encountered situations that were characterised by conflicting pressures, and handled these by way of interaction, sense making, presenting arguments, negotiating and seeking support for an appropriate course of action and practices. The policy work with limit-setting can therefore be regarded as a dynamic interactive process, which incorporates several actors in different situations and locations, together negotiating and institutionalising the policy. Various policy sites, which had the role of mediating institutions, were identified, and were important in the interactive processes of forming a shared collective meaning in order to reach an appropriate act. Hence, designing legitimacy has to acknowledge the interactive policy work, and its contextual character, taking place at the different levels of a healthcare system.

This study investigated the effects of the positive behavior support program Family HOPE conducted in homes of families of children with disabilities. Graduate students conducted an 8-10 week collaborative method of training for parents of children with disabilities to reduce problem behaviors of their child with a disability. The Parent-Child Relationship Inventory (PCRI) and Scales of Independent Behavior-Revised (SIB-R) were given to both experimental and control group families to investigate the program effects on parents' perceptions of limit setting, parental support, frequency and severity of problem behaviors. Results indicated that there was not a significant pre-post difference for either group on limit setting and parental support. There was a significant decrease in the frequency and severity of problem behaviors on the SIB-R for the treatment and control groups; however, no significant difference was found according to group membership. On subscales of Limit Setting and Parental Support on the PCRI no significant differences were found between control and experimental groups. Implications for further research are suggested and include items such as the control group size and using measures that are sensitive enough to detect changes in behavior over a short period of time.

This thesis presents three searches for new resonances in dijet invariant mass spectra. The spectra are produced using √s = 13 TeV proton-proton collision data recorded by the ATLAS detector. New dijet resonances are searched for in the mass range 200 GeV to 6.9 TeV in mass. Heavy new resonances, with masses above 1.1 TeV, are targeted by a high mass dijet search. Light new resonances, with masses down to 200 GeV, are searched for in dijet events with an associated high momentum object (a photon or a jet) arising from initial state radiation. The associated object is used to efficiently trigger the recording of low mass dijet events. All of the analyses presented in this thesis search for an excess of events, localised in mass, above a data-derived estimate of the smoothly falling QCD background. In each search no evidence for new resonances is observed, and the data are used to set 95% C.L. limits on the production cross-section times acceptance times branching ratio for model-independent Gaussian resonance shapes, as well as benchmark signals. One particular benchmark signal which is considered in all of the searches is an axial-vector Z' dark matter mediator model whose parameter space is reduced due to the results presented in this thesis.

With the advent of the internet, the opportunity to gamble for money is no longer limited by opening hours or that gambling is only available in specific places, which has meant that more and more people have developed an unhealthy relationship with gambling. Having an unhealthy relationship with gambling can have several negative consequences. To address this problem, relatively new legislation has been introduced in Sweden. According to the new legislation, all companies with a Swedish gambling license must implement responsible gambling tools. The purpose of these tools is to encourage users to play in a healthy manner. The results in existing research and literature on responsible gambling tools are contradictory, but in general it has emerged that responsible gambling tools have a low impact, especially among the players who have the greatest need for them, as they do not use the tools in a proper way. This study aims to investigate why responsible gambling tools have low impact among players with gambling problems. The study has a qualitative research approach with semi-structured interviews as a method for data collection. With this as a starting point, eight semi-structured interviews were conducted in which the informant was asked to explain opinions and perceptions about gambling responsible tools. The interviews were analyzed through a thematic analysis, which resulted in seven themes that individually and together can explain the study's purpose. The themes the study found were interpretable legislation, unlicensed gambling, lack of standardization, lack of centralization, lack in user knowledge, lack in provided information and a lack in self-exclusion tools. This study also develops the general knowledge of what the view of responsible gambling tools looks like from the various actors. The themes presented will also be a contribution, that can be used in future research and continued development of responsible gambling tools. / I och med internets framväxt är möjligheten att spela om pengar inte längre begränsad av öppettider eller av specifika platser, vilket medfört att allt fler har utvecklat ett osunt förhållande till spel. Att ha ett osunt förhållande till spel om pengar kan få negativa konsekvenser. För att bemöta detta problem har en relativt ny lagstiftning införts. Alla bolag med svensk spellicens måste enligt den nya lagstiftningen implementera så kallade spelansvarsverktyg. Syftet med dessa verktyg är att uppmuntra användarna att spela på ett sunt sätt. Tidigare forskningsstudier och litteratur om spelansvarsverktyg är motsägelsefulla, men generellt har det framkommit att spelansvarsverktyg har en liten effekt speciellt på de individer som har störst behov av dem, då dessa inte använder spelansvarsverktygen.  Denna studie avser att undersöka varför spelansvarsverktyg har liten effekt på spelare med spelproblem. Studien har en kvalitativ forskningsansats med semistrukturerade intervjuer som metod för datainsamling. Med detta som utgångspunkt genomfördes åtta semistrukturerade intervjuer där informanterna ombads redogöra för åsikter och uppfattningar om spelansvarsverktyg. Resultatet har analyserats genom en tematisk analys som resulterat i sju teman som var för sig och tillsammans förklarar studiens syfte och frågeställning. De sju teman var: icke licensierade spel, bristande lagstiftning, avsaknad av centralisering, avsaknad av standardisering, brister i användarkunskapen, avsaknad av information och brist i självuteslutning. Denna studie bidrar också med kunskap om hur de olika aktörerna ser på spelansvarsverktyg. De presenterade temana blir således ett bidrag som kan användas i framtida forskning och fortsatt utveckling av spelansvarsverktyg
