Changes to homelessness legislation in post-devolution Scotland have resulted in an expansion of rights for homeless households seeking formal assistance from local authorities. These changes have led to Scotland’s homelessness arrangements being considered among the most progressive in Europe. In recent years, however, the Scottish Government has increasingly promoted homelessness prevention and Housing Options approaches as a means by which homelessness might be avoided or resolved without recourse to statutory rights. As part of that, they have promoted greater use of the private rented sector (PRS) as a key housing option, with the potential to meet the needs of homeless households. The arguments made to support use of the PRS have much in common with arguments for privatisation in other areas of social policy, notably greater choice for the individual promoting better welfare outcomes, and competition among providers encouraging improvements in quality of service provision. Critics have argued that such benefits may not be realised and that, on the contrary, privatisation may lead to exclusion or act to worsen households’ outcomes. This thesis considers the extent to which the PRS has been utilised in Scotland to accommodate homeless households, and the consequences of this for their welfare. The thesis uses a combination of quantitative and qualitative methods. To examine trends in the use of the PRS, it presents quantitative analysis of the data on the operation of the statutory system and Housing Options arrangements, and of data from a survey of local authority homelessness strategy officers. To examine the consequences of this for homeless households, the thesis uses qualitative research involving face-to-face interviews with 35 homeless households across three local authority areas. This research considers the extent to which households’ experiences of homelessness, housing need and the PRS reflect the arguments presented in the literature, and how settled accommodation has impacted on households’ ability to participate fully in society. The research found an increasing but still limited role for the PRS in resolving statutory homelessness in Scotland, with indications that the PRS is being increasingly used as part of the Housing Options approach and as a means of resolving homelessness outside the statutory system. The PRS is being utilised to varying degrees across different local authority areas, and a variety of methods are being used to do so. While local authorities saw clear advantages to making greater use of the sector, a number of significant barriers including affordability, available stock and landlord preferences - made this difficult in practice. Research with previously homeless households in the PRS similarly found broadly positive experiences and views of the sector, particularly with regard to enabling households to access good quality accommodation in desirable areas of their choosing, with many households highlighting improvements relating to social inclusion and participation. Nevertheless, concerns around the security of tenure offered by the sector, repairs, service standards and unequal power relations between landlord and tenant persisted. As such, homeless households frequently expressed their decision to enter the sector in terms of a trade-off between choice and security.

Liquid chromatography coupled with mass spectrometry is one of the most powerful tools in the toxicologist’s arsenal to detect a wide variety of compounds from many different matrices. However, the huge number of potentially abused substances and new substances especially designed as intoxicants poses a problem in a forensic toxicology setting. Most methods are targeted and designed to cover a very specific drug or group of drugs while many other substances remain undetected. High resolution mass spectrometry, more specifically time-of-flight mass spectrometry, represents an extremely powerful tool in analysing a multitude of compounds not only simultaneously but also retroactively. The data obtained through the time-of-flight instrument contains all compounds made available from sample extraction and chromatography, which can be processed at a later time with an improved library to detect previously unrecognised compounds without having to analyse the respective sample again. The aim of this project was to determine the utility and limitations of time-of-flight mass spectrometry as a general and easily expandable screening method. The resolution of time-of-flight mass spectrometry allows for the separation of compounds with the same nominal mass but distinct exact masses without the need to separate them chromatographically. To simulate the wide variety of potentially encountered drugs in such a general screening method, seven drugs (morphine, cocaine, zolpidem, diazepam, amphetamine, MDEA and THC) were chosen to represent this variety in terms of mass, properties and functional groups. Consequently, several liquid-liquid and solid phase extractions were applied to urine samples to determine the most general suitable and unspecific extraction. Chromatography was optimised by investigating the parameters pH, concentration, organic solvent and gradient of the mobile phase to improve data obtained by the time-of-flight instrument. The resulting method was validated as a qualitative confirmation/identification method. Data processing was automated using the software TargetAnalysis, which provides excellent analyte recognition according to retention time, exact mass and isotope pattern. The recognition of isotope patterns allows excellent recognition of analytes even in interference rich mass spectra and proved to be a good positive indicator. Finally, the validated method was applied to samples received from the A& E Department of Glasgow Royal Infirmary in suspected drug abuse cases and samples received from the Scottish Prison Service, which we received from their own prevalence study targeting drugs of abuse in the prison population. The obtained data was processed with a library established in the course of this work.
