Trafficking in human beings for for forced labour in domestic and international law: a comparative legal study of the kingdom of Saudi Arabia and the United Kingdom

This thesis examines the effect of combating of human trafficking as a crime. Special emphasis has been placed on forced labour and the rights of trafficked victims and their protection. The study explores various legislations undertaken at regional, national and international levels and considers rights of trafficked victims under international human rights and Islamic rights. The aim of the thesis is to provide a critical and comparative analysis of the legal systems of the Kingdom of Saudi Arabia (KSA) and the United Kingdom (UK) in terms of human trafficking. The thesis consists of eight chapter; each covering a different aspect of the study. It begins by providing background information regarding the issue of human trafficking and proceeds to examine developments of legal frameworks across the two jurisdictions to combat this crime and penalize the criminals. It seeks to examine the legal system pertaining to human trafficking for forced labour and analyse the three distinct platforms, that is, prevention, protection, and punishment, by comparing the legal systems of the KSA and the UK. The examination of both countries aims to identify the strength and weaknesses of the KSA system as compared to the UK system. Thus, it concludes that the KSA can improve its ranking from Tier 2 watch list to Tier 1 if reforms are introduced in the legislation and enforcement domains. The study also demonstrates how the UK and the KSA portray ‘human trafficking’ in their regional laws. A problem often faced during the information-gathering and investigation stages is the lack of available evidence against traffickers, a particular issue in the KSA. The thesis concludes that the transnational aspect of this phenomenon makes it necessary to establish a thorough and comprehensive legal framework to cover all matters pertaining to this crime, including the protection of victims and punishment of criminals in the KSA and the UK, including immigration and ‘kafala’ strategies that may be of value in future researches.

Navigating uncertain waters: a critical review of inferring foraging behaviour from location and dive data in pinnipeds

In the last thirty years, the emergence and progression of biologging technology has led to great advances in marine predator ecology. Large databases of location and dive observations from biologging devices have been compiled for an increasing number of diving predator species (such as pinnipeds, sea turtles, seabirds and cetaceans), enabling complex questions about animal activity budgets and habitat use to be addressed. Central to answering these questions is our ability to correctly identify and quantify the frequency of essential behaviours, such as foraging. Despite technological advances that have increased the quality and resolution of location and dive data, accurately interpreting behaviour from such data remains a challenge, and analytical methods are only beginning to unlock the full potential of existing datasets. This review evaluates both traditional and emerging methods and presents a starting platform of options for future studies of marine predator foraging ecology, particularly from location and two-dimensional (time-depth) dive data. We outline the different devices and data types available, discuss the limitations and advantages of commonly-used analytical techniques, and highlight key areas for future research. We focus our review on pinnipeds - one of the most studied taxa of marine predators - but offer insights that will be applicable to other air-breathing marine predator tracking studies. We highlight that traditionally-used methods for inferring foraging from location and dive data, such as first-passage time and dive shape analysis, have important caveats and limitations depending on the nature of the data and the research question. We suggest that more holistic statistical techniques, such as state-space models, which can synthesise multiple track, dive and environmental metrics whilst simultaneously accounting for measurement error, offer more robust alternatives. Finally, we identify a need for more research to elucidate the role of physical oceanography, device effects, study animal selection, and developmental stages in predator behaviour and data interpretation.
