This thesis examines the effects on vegetation at selected sites in northern South Australia of excluding various herbivores over a four and a half year period and of two intense but controlled grazing pulses over a six month period followed by an 18 month recovery period in a dune-swale land system. These changes are compared with changes recorded over an 11-year period at the Olympic Dam mine site. It found that short-term changes in vegetation revealed by ordination of periodical cover, density and species richness, are attributable to the periodicity of rainfall and that, under present grazing regimes, rainfall effects override grazing effects. Differences between the effects of sheep and cattle hoof damage are worthy of further investigation, as is the impact of kangaroo grazing. These two factors may have important implications for the management of Australian rangelands.

In today’s society, many people are physically inactive and the health care is for example usingPhysical activity on prescription (PaP) to work against it. In order to increase the physical activitylevel in people they need to feel motivated and there are many factors that can motivate people. The purpose of this survey is therefore to explore the leaders of PaP and their thoughts about whatmotivates clients with PaP to increase their physical activity levels. This is explored by aqualitative method incorporated with semi-structured interviews with four respondents who workswith PaP. The results were analyzed with a descriptive method that contributed to a narrativeanalysis, which was interpreted at some levels. The result showed that the primary methods therespondents used to motivate the clients with PaP was to set goals together and to individualize themotivational work. It was also important to the PaP-client to feel secure and it could be achievedthrough a good attitude and an understanding of why and how the PaP-client needed to implementa lifestyle-change. Finally, the most important was to investigate how the lifestyle-change processgone, through a follow-up. / I dagens samhälle är många människor fysiskt inaktiva och detta arbetar hälso- och sjukvårdenmot med hjälp av bland annat Fysisk aktivitet på recept. För att öka den fysiska aktiviteten hosmänniskor krävs att de har motivation och det finns många olika faktorer som kan motiveramänniskor. Syftet i denna undersökning var således att undersöka vad FaR-ledare ansåg motiverarFaR-klienter till att öka sin fysiska aktivitet. Detta undersöktes via en kvalitativ studie sominnehöll delvis strukturerade intervjuer med fyra respondenter som arbetade med Fysisk aktivitetpå recept. Resultatet analyserades sedan med en deskriptiv metod som bidrog till en berättandeanalys som tolkades i viss mån. Resultatet visade att de främsta metoderna respondenternaanvände sig av för att motivera FaR-klienterna var att sätta upp mål tillsammans ochindividanpassa motivationsarbetet. Det var även viktigt att FaR-klienten kände trygghet och detkunde uppnås via ett bra bemötande och förståelse för varför och hur denne ska genomföralivsstilsförändringen. Slutligen var det centralt att undersöka hur förändringsarbetet gått via uppföljning.

This study offers the first instalment of a general history of land acquisition in British India, c. 1894–1927. It advances eight principal theses: (i) that the first law of land acquisition was enacted in 1668, as part of a political settlement by the East India Company with the Portuguese landlords of Bombay island; (ii) that, to a remarkable degree, land acquisition law was shaped in the interest of the sterling railway companies; (iii) that the state habitually used land acquisition not so much to effect non- consensual transfers but to ‘launder’ titles free of encumbrances and other claims; (iv) that the primary beneficiaries of land acquisition were public bodies, the sterling railway companies, and elite private interests; (v) that the executive was hostile to legislative and judicial oversight of land acquisition, and successfully resisted or co-opted attempts to impose such oversight; (vi) that the courts were in any event content with the role they were assigned under the 1894 Act, and generally deferred to the executive in land acquisition cases; (vii) that the land-acquiring executive, although hostile to and unencumbered by meaningful legislative and judicial oversight, as a general rule displayed a legal fastidiousness; (viii) that, despite an appearance of impartiality, land acquisition bore the stain of imperialism. These theses are advanced in the course of explaining the failure of the forgotten Kelkar Bill (1927), an attempt by the Maharashtrian nationalist N. C. Kelkar (1872–1947) to enact far-reaching amendments to the Land Acquisition Act 1894. Kelkar’s fellow nationalists withheld their open support from the measure and thereby guaranteed its failure: a counterintuitive choice that, it is argued, exemplifies the tactical compromises of nationalism.

This thesis presents a detailed study of the impact of radio-AGN on star formation and the interstellar medium (ISM) of galaxies across cosmic time. To do this, this thesis uses far-IR/sub-mm data from the Herschel Space Observatory. I create a well-selected sample of 1599 radio sources using the NRAO VLA Sky Survey (NVSS) and Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) data in combination with the UKIRT Infrared Deep Sky Survey - Large Area Survey (UKIDSS - LAS) data. I find that the far-IR luminosities and dust temperatures of radio galaxies are lower in comparison to those of non-radio-detected galaxies. This luminosity deficit grows with increasing stellar mass. I argue that the reasons for these differences is probably due to indirect radio-AGN feedback, i.e. radio jets mechanically heat the halo-environment, preventing external sources of cold gas from entering the host and forming stars. The far-IR luminosity and dust temperature is found to decrease as a function of radio source size. I find the most likely explanation for this is jet-induced star formation while the jets are confined to the ISM. Finally, a method for identifying reliable high-z, star-bursting radio sources in the H-ATLAS is described with which statistically significant studies of radio-jet induced star formation may be undertaken.

<p>Syftet med studien är att undersöka pedagogers ansvarstagande och inställning till anmälningsplikt av barn som far illa. Vi vill också ta reda på om de ändrar sitt förhållnings- och arbetssätt gentemot det utsatta barnet och barngruppen samt om pedagogerna anser att de får tillräckligt med stöd vid en anmälningsprocess.</p><p>I studien har vi valt att använda oss av enkäter. Vi delade ut enkäterna till alla pedagoger på två olika skolor. Av 44 utdelade enkäter fick vi tillbaka 33 och vi använde oss av 32 stycken.</p><p>Resultatet visar att flertalet av pedagogerna var medvetna om anmälningsprocessen av barn som far illa. De som anmält misstanke om barn som far illa till socialtjänsten kände känslor som exempelvis ledsamhet, osäkerhet och psykisk påfrestning. Hälften av pedagogerna hade inte anmält misstanke och den främsta anledningen var att de inte stött på barn som far illa. Andra anledningar var känslor som osäkerhet och rädsla. Många ansåg att de inte förändrade förhållningssätt gentemot barnet och barngruppen. De pedagoger som ansåg sig delvis ha förändrat sitt förhållningssätt kommenterade det som att de kände mer förståelse och var mer observanta mot barnet. Flertalet av pedagogerna kände att de fick tillräckligt med stöd vid en anmälan, stödet kom från exempelvis rektor/ledning, specialpedagog och arbetslag. Majoriteten ansåg att det behövs mer kunskap om barn som far illa och anmälningsprocessen.</p>

Protoplanetary discs set the initial conditions for planet formation. By combining observations with detailed modelling, it is possible to constrain the physics and chemistry in such discs. I have used the detailed thermo-chemical disc model ProDiMo to explore the characteristics of the gas in protoplanetary discs, particularly in Herbig Ae objects. I have assessed the ability of various observational data to trace the disc properties. This has involved a number of different approaches. Firstly I compute a series of disc models with increasing mass, in order to test the diagnostic powers of various emission lines, in particular as gas mass tracers. This approach is then expanded to a large multiparameter grid of ~ 10 5 disc models. I have helped to develop a tool for analysing and plotting the huge quantity of data presented by such a model grid. Following this approach I move on to a detailed study of the Herbig Ae star HD 163296, attempting to fit the large wealth of available observations simultaneously. These include new Herschel observations of the far-infrared emission lines, as well as interferometric CO observations and a large number of continuum data. This study addresses the topical issues of the disc gas/dust ratio, and the treatment of the disc outer edge. It explores the effects of dust settling, UV variability and stellar X-ray emission on the disc chemistry and line emission. There is possible evidence for gas-depletion in the disc of HD 163296, with the line emission enhanced by dust settling, which would indicate a later evolutionary stage for this disc than suggested by other studies. Finally, I work to improve the treatment of the gas heating/cooling balance in ProDiMo, by introducing a non-LTE treatment of the atomic hydrogen line transitions and bound-free continuum transitions. I explore the effects of this on the disc chemical and thermal structure, and assess its impact in terms of the observable quantities.

Arbetet behandlar problematiken om elever som far illa i hemmet, ett känsligt, viktigt och emotionellt svårt område. Genom kvalitativa intervjuer med pedagoger och andra personer som har varit i kontakt med ämnet, presenterar arbetet hur intervjupersonerna resonerar om bemötandet och upptäckandet av dessa elever. Arbetet tar även upp hur pedagoger går vidare med sina misstankar. Resultatet visar att pedagoger måste vara uppmärksamma på olika signaler elever och deras föräldrar sänder ut. Det kan röra sig om förändrat beteendemönster eller kläder som inte är passande för vädret.  Intervjupersonerna menar att de vuxna inte ska göra skillnad i sitt bemötande av elever med svårigheter i hemmet och andra elever. Vuxna som arbetar där elever som far illa i hemmet vistas måste visa att de finns till om eleven vill prata, och skapa en trygg miljö där eleven känner sig välkommen och behövd. Detta ökar möjligheten att eleven berättar om sina problem och på så sätt kan få hjälp.

This thesis describes an experimental study of high intensity, pulsed, optically pumped, far-infrared (FIR) lasers. The work was motivated by the need for a radiation source for the measurement of the ion temperature in magnetically confined, high temperature plasmas (e.g. tokamak plasmas), using Thomson scattering. Constraints imposed by the plasma parameters, the scattering geometry and available detector sensitivities lead to the requirement of a radiation source wavelength between 30μm and 1mm and a source power . 1 MW in a bandwidth 60 MHz. Results are presented for a 496μm, 500 watt, methyl fluoride (CH₃F) cavity laser, with a bandwidth of and < 30MHz, which was optically pumped by a 9.55μm CO₂ laser. Results are also presented for an optically excited mirrorless, super-radiant, CH₃F laser, which generated over 0.6MW of FIR radiation within a bandwidth of about 300MHz. The performance of this laser has also been simulated by a computer model, which allows the optimum operating parameters to be predicted. An assembly constructed on the principle of the injection laser, in which low power narrow-band oscillator radiation is used to control the output of a super-radiant system, has been used to generate 250 kW of 496 andmu;m radiation, with a bandwidth of < 60 MHz. Investigations of the FIR output from heavy water vapour (D₂O) in a super-radiant laser assembly, optically excited by several different CO₂ laser wavelengths, have resulted in the generation of 60 ns (FWHM) pulses of FIR radiation with average powers of 1.3, 9.2 and 15.8MW, at wavelengths of 385, 119 and 66μm, respectively. All these lasers were found to have a higher CO₂ to FIR photon conversion efficiency than the 496μm CH₃F laser. In addition, the energy level spacing in D₂O is such that the molecule can generate narrow bandwidth radiation more readily than the CH₃F molecule. From this work it is concluded that an injection laser assembly, similar to that used with CH₃F, but containing D₂O vapour, optically pumped by a 9.26μm CO₂ laser and generating several megawatts of 385μm radiation, would satisfy the source requirements mentioned above.
