An analytical dispersion model has been derived to determine the distribution of velocities and concentrations of a tracer in a two-dimensional jet in a coflowing ambient fluid. The particular novelty of this model is that it bridges the gap between near-field (where initial momentum dominates behaviour) and far-field (where ambient turbulence is more important) domains. We describe this domain as the ???intermediate field???. In a literature review of coflowing jets we find several laboratory studies and models which can predict the velocities (and in some cases concentrations) in a 2D jet, however they all have shortcomings. None could fully account for ambient turbulence, and all were strictly near-field, i.e. they are unable to describe behaviour when ambient turbulence dominates the initial shear. A brief review of analytical far-field models was also undertaken. There are standard solutions for the dispersion of a 2D continuous source but none that allow for an initial source momentum or non-uniform velocity. As opposed to the near-field coflow approach used by other researchers we start from the far-field, modifying the simple diffusion models by perturbing the governing equations to allow for the initial momentum. Models are developed for both along-stream velocity and the concentration field of a tracer. From the velocity model, a comparison is made with experimental data available from one researcher (Wang, 1996) and an existing near-field coflow model PJCMERG (Davidson, 1989). The initial conditions (width and excess velocity) for our model are determined by Gaussian curve fitting to an arbitrary point in the near-field. The diffusivity parameter is used to adjust (tune) the model until the centreline velocity profile matches. We can always achieve this match and to a much closer degree than PJCMERG. There are no available laboratory or field data for concentrations of a tracer in a 2D coflowing jet although the near-field model PJCMERG does have a tracer component. We demonstrate how PJCMERG cannot converge to any far-field model, while our model provides a neat transition between the near-field and far-field. We have started the extension of the 2D model to the more common 3D situation although we have yet to carry out any comparisons with other models or data. The model development is included in an appendix for other researchers to pick up.

<p>Redovisningskonsulter har tidigare inte haft en tydlig yrkesroll men den senaste tiden har förändringar skett i branschen och fler är att vänta inom en snar framtid. Studien syftar till att undersöka vad redovisningskonsulter anser om förändringarna och hur det kommer att påverka deras yrkesroll. Förändringarna studien behandlar är auktorisationen av redovisningskonsulter, slopandet av revisionsplikten och förändrade redovisningsregler. Den teoretiska referensramen ger läsaren en inblick i förändringarna och för att ta del av redovisningskonsulters åsikter har fyra personliga intervjuer genomförts.</p><p>Slutsatser som kan dras är att det i nuläget är upp till redovisningskonsulten hur stor förändring den gör i sitt arbete då de har valmöjligheter inom samtliga områden som studien tagit upp. Auktorisationen är ett välkomnat initiativ som ger redovisningskonsulterna en tydligare yrkesroll medan de förändrade redovisningsreglerna inte kommer tillämpas i stor utsträckning av respondenterna i studien. Slopandet av revisionsplikten kan komma att innebära ett större ansvar för redovisningskonsulterna men även här beror det helt på valen som görs. Studien tar upp de intervjuade redovisningskonsulternas åsikter och vilka val de gjort.</p>

British politics at the start of the 21st century provide a good setting for examining factors associated with mobilisation for extremist politics. This thesis is concerned with the relationship between individuals' preferences, their local setting and political behaviour. With focus on two outcomes - participation in urban rioting and support for a far right party - this thesis is divided into two parts and consists of five research papers addressing different aspects of mobilisation. In the first part we focus on urban disorder and examine police arrest records from the London riot of 2011. Much of the sociological literature has focused on variation in rioting across cities; here we examine variation within London by mapping the residential addresses of 1,620 rioters onto over 25,000 neighbourhoods. Our findings challenge the orthodoxy that rioting is not explained by deprivation or by disorganisation. Furthermore, we present evidence suggesting the importance of political grievances, in particular relations with the police, and examine the process of mobilisation to show that it was aided by spatial proximity and social similarity. In the second part we look at factors associated with engagement with far right politics. We use individual attitudinal data from the British Election Study to examine whether concerns over immigration are associated with the actual experience of immigration in one's place of residence. The results suggest that local setting does play some role, although individual factors seem to be more important. Secondly, we use leaked British National Party membership list to map 12,536 far right supporters onto over 200,000 neighbourhoods in Britain. Our findings underline the importance of a larger geographic context, where some spatial configurations present particularly fertile grounds for the far right; we also report the relative unimportance of cultural threat and significance of the social distance. Lastly, we question the recently advocated 'legacy effect' and suggest that white flight mechanism may possibly be an alternative way of thinking about organisational continuity.
