description: Motion planners are essential for the safe operation of automated vehicles across various scenarios. However, no motion planning algorithm has achieved perfection in the literature, and improving its performance is often time-consuming and labor-intensive. To tackle the aforementioned issues, we present DrPlanner, the first framework designed to automatically diagnose and repair motion planners using large language models. Initially, we generate a structured description of the planner and its planned trajectories from both natural and programming languages. Leveraging the profound capabilities of large language models, our framework returns repaired planners with detailed diagnostic descriptions. Furthermore, our framework advances iteratively with continuous feedback from the evaluation of the repaired outcomes. Our approach is validated using both search- and sampling-based motion planners for automated vehicles; experimental results highlight the need for demonstrations in the prompt and show the ability of our framework to effectively identify and rectify elusive issues.

title: Coping With the Chaos (Bardak): Chaos, Networking, Sexualised Strategies and Ethnic Tensions, in Almaty, Kazakhsatan.
Creators: name: Rigi, J.
Publisher: name: School of Oriental and African Studies, University of London
Year: 1999

description: The aim of thesis is to describe and analyse the main elements of the post- Soviet chaos (bardak) in Almaty, Kazakhstan. My focus is the ways in which the dispossessed people understand and react to what they term 'chaos' and their own dispossession and the variety of coping strategies they have adopted to survive in the new, harsh economic and political environment. My account draws on 15 months 'multi-site' ethnographic fieldwork in Almaty from July 1995 to Oct 1996. What dispossessed describe as 'chaos' are the circumstances of their plunder: a situation which they think has been deliberately created by members of the former Soviet elite and a variety of Westerners. It is, I argue, a situation created and exploited by the Kazakhstan state official and others, locally known as 'the mafia' (mafiia) as part of their response to the collapse of the USSR, and the new liberal economic policies associated with the new style of 'global capitalism'. Their response also includes many forms of corruption, and a willingness to use violence against increasingly impoverished majority of the population. I particularly focus on networking and sex work as two important strategies through which the dispossessed cope with the poverty and social insecurity. One finding of considerable importance is that while network-based competition for resources has given a new surge to ethnic tensions in Kazakhstan, such tensions are counterbalanced among the dispossessed by their feeling of belonging to the same Soviet 'imagined community' (Sovetskii narod). Central to such feelings is a strong shared nostalgia for the Soviet era. This nostalgia signals a fear of, and constitute a form of protest against, some elements of post-Soviet change such as the implementation of market economy, widespread prostitution, the presence of foreigners, the emergence of new forms of class differentiation and the prevalence of consumerist culture and the monetisation of life worlds, particularly with respect to sexual relations. The dispossessed not only reject these changes but attribute them to corrupt 'alien' evil forces: alien persons, the alien consumerist culture and the 'wild capitalism' (diki kapitalism). An examination of the complex responses of dispossessed to these 'alien' forces is the theme which unites this dissertation. In particular I document the ways in which both the imagined Soviet community, and those of other imagined ethnic communities are gendered through discourses and practices related to sexuality and marriage. I also describe how the dispossessed, of whatever the ethnic or religious backgrounds, often feel themselves to have far more in common with each other, and with others of the dispossessed throughout the territory of the former USSR, than with their co-ethnics or co-religionists outside this territory.
title: Style and Ascetics: Attractiveness, Power and the Thai Sangha.
Creators: name: Songkhla, Natayada na
Publisher: name: School of Oriental and African Studies, University of London
Year: 1999

description: The majority of research for this thesis took place during the Thai general election of 1988 when the new religious movements Santi Asoke and Wat Dhammakaya were subject to investigation for political activity despite, respectively, defiance or denial. The relationship between the Thai Sangha and lay devotees is examined in order to discover how it is that Thai monks, whom many researchers find powerless, can be accused of political activity. In the past, monks have been used to legitimate lay political leaders and have taken active roles in local leadership. This thesis aims to determine whether monks in Thailand have power and, if they do, how such power becomes politically threatening to the status quo. As is suggested by the rise of new movements, the Thai Sangha is not an institution of uniform standard and activity; monks often appear different from each other in subtle yet distinctive ways and these differences can be noted by the lay public. Differences in appearance often reflect variations in monks' pastoral involvement in the lay community. In short, there are different styles of Thai monk, each with a lay following which is attracted to his particular style. There are four factors which effect the relationship between the Thai Sangha and the lay public: monks, devotees, temples and day-to-day religious life. Each of these factors - among the mainstream Sangha, Santi Asoke and Wat Dhammakaya - are examined, compared and contrasted in order to determine the nature of monastic powder in Thailand and how that power works in society to allow' the Sangha to act as legitimators and local leaders and, on occasion, to be perceived as a threat. Particular attention is given to the devotees and the style of monk they find attractive. It is this attraction that is the basis of monastic power.
title: The Theory and Politics of Mountain Rangeland Conservation and Pastoral Development in Colonial Lesotho.
Creators: name: Driver, Thackwray
Publisher: name: School of Oriental and African Studies, University of London
Year: 1998

description: During the 1930s and 1940s there was a huge increase in state interventions into the African rural economy, society and environment by both British colonial and settler governments. These interventions, carried out in the name of conservation and development, have received increased attention from historians in recent years, crucially because of the often violent opposition they encountered from the supposed beneficiaries, but also because of the apparent continuity between colonial and postcolonial development interventions. This thesis traces the history of colonial conservation and development policies in the mountain zone of Lesotho. As the vast majority of the area is given over to communal grazing it is hardly surprising that these interventions concentrated almost exclusively on the livestock sector. The major colonial intervention in the mountain livestock sector consisted of a policy to close totally a huge swathe of communal grazing land, in order to allow the range to return to its 'climatic climax'. The discourse of conservation and development in Lesotho was broadly similar to elsewhere in Africa, though the specific policies were largely shaped by local concerns. The thesis traces the development of this discourse and identifies the reasons why colonial officials became concerned about the mountain environment. The thesis places a particular stress on the science that informed colonial officials' understanding of the mountain ecology and allowed them to draw conclusions about environmental change, despite the almost total lack of data. In contrast to many similar policies attempted elsewhere, there are no reports of resistance in Lesotho, despite the fact that the major policy (the grazing closures) would have had a huge impact on the livelihoods of local communities. The thesis argues that the reason that there was no resistance was that the policy was never actually implemented, despite the official reports of success. An explanation for this gap between rhetoric and reality has to be sought in the realm of local, national and international politics.

title: The Tientsin Incident (1939): A Case-Study of Japan's Imperial Dilemma in China.
Creators: name: Swann, Sebastian P.
Publisher: name: School of Oriental and African Studies, University of London
Year: 1999

description: This is a study of an incident that took place in North China when the Japanese Army decided to institute a blockade around the British and French Concessions at Tientsin on 15 June 1939. This precipitated a serious international crisis between Japan, Britain and China, although other countries, in particular the United States and France, were also involved. The crisis was in large part defused by the middle of September 1939, although the blockade of the British and French areas would not be lifted until June 1940. This was one of many incidents between Japan, China and the western imperial powers in Asia that occurred in the wake of Japan's invasion into China, particularly from July 1937. The object of this study is to determine why, unlike many of these other events, the Tientsin Incident escalated into a crisis and how it could be defused almost nine months before the blockade of the British and French Concessions would eventually be raised. This is a multi-archival work. But particular emphasis has been put upon the analysis of Japanese primary materials in order to discover the light this Incident can shed upon the nature and problems of Japanese imperial expansion into Asia, and how this affected the course of Anglo-Japanese relations. We examine the extent to which the political dynamics of this conflict were decided by the situation in Tientsin as opposed to the conflict in China as a whole and the tensions that it was putting on Japan's body-politic. We also examine to what extent the Incident acted as a catalyst in promoting a more confrontational relationship between Japan and the Western Powers. Finally, we try to make an assessment of the implications of this event both for China and other Asian countries that would later follow China's lead in seeking to deal with their foreign imperial conquerors --- Japanese or Western --- upon a more equal footing.

description: Established techniques that enable robots to learn from demonstrations are based on learning a stable dynamical system (DS). To increase the robots' resilience to perturbations during tasks that involve static obstacle avoidance, we propose incorporating barrier certificates into an optimization problem to learn a stable and barrier-certified DS. Such optimization problem can be very complex or extremely conservative when the traditional linear parameter-varying formulation is used. Thus, different from previous approaches in the literature, we propose to use polynomial representations for DSs, which yields an optimization problem that can be tackled by sum-of-squares techniques. Finally, our approach can handle obstacle shapes that fall outside the scope of assumptions typically found in the literature concerning obstacle avoidance within the DS learning framework.

title: Oil, Economic Growth and Structural Change in the Libyan Economy, 1960-1990.
Creators: name: Aboulsayan, Ahmed
Publisher: name: School of Oriental and African Studies, University of London
Year: 2000

description: The subject of this study is the influence of an oil boom on the economic growth and structure of a open small economy with reference to Libya following the discovery of oil. The relevant theoretical literature is based upon the Dutch Disease theory. After a survey of the literature upon this theory, the study investigates the economic growth and structural changes which occurred in the Libyan economy during the three decades to 1990. The analysis is conducted within a time-frame composed of three distinct periods: these are the pre-boom period, the boom period and the post-boom period. Historical trends depicted within these periods show that the Libyan economy had undergone several fundamental structural changes and that the biggest of these took place during the oil price shock period between 1973-1982. The investigation examines Libya's experience of sectoral shifts and the performance of the agriculture and manufacturing sectors under booming conditions. It is shown that in both these sectors booming conditions brought about rapidly increased demand, relative price changes and change of technical conditions of production. These in tum led to rapid expansion in the manufacturing sectors share within the total tradables output combined with a decline in the share for agriculture. The study demonstrates that the fall in the share of agriculture was the result of fast industrialisation rather than the Dutch Disease effect. In general the study reveals that speedy growth of oil export revenues was associated with high investment and economic activity in commodity producing sectors (manufacturing and agriculture) and that the period of slump in oil revenues had coincided with slower growth and lower investment in these sectors. The study's main finding is that the problems encountered in the Libyan economy were not those predicted by the Dutch Disease but that they were more directly connected with the efficiency of investment and government strategy toward the industrialisation process.
Motility driven glassy dynamics in confluent epithelial monolayers

description: As wounds heal, embryos develop, cancer spreads, or asthma progresses, the cellular monolayer undergoes glass transition between solid-like jammed and fluid-like flowing states. During some of these processes, the cells undergo an epithelial-to-mesenchymal transition (EMT): they acquire in-plane polarity and become motile. Thus, how motility drives the glassy dynamics in epithelial systems is critical for the EMT process. However, no analytical framework that is indispensable for deeper insights exists. Here, we develop such a theory inspired by a well-known glass theory. One crucial result of this work is that the confluency affects the effective persistence time-scale of active force, described by its rotational diffusivity, $D_r^{\text{eff}}$. $D_r^{\text{eff}}$ differs from the bare rotational diffusivity, $D_r$, of the motile force due to cell shape dynamics, which acts to rectify the force dynamics: $D_r^{\text{eff}}$ is equal to $D_r$ when $D_r$ is small and saturates when $D_r$ is large. We test the theoretical prediction of $D_r^{\text{eff}}$ and how it affects the relaxation dynamics in our simulations of active Vertex model. This novel effect of $D_r^{\text{eff}}$ is crucial to understanding the new and previously published simulation data of active glassy dynamics in epithelial monolayers.

title: The Mixed Courts of Egypt, 1875-1949: A Study of Their Development and Operation, and Their Influence on Post-War Egyptian Law.
Creators: name: Hoyle, Mark Stanley Wadih
Publisher: name: School of Oriental and African Studies, University of London
Year: 1983

description: This study starts with an Introduction, describing the historical background of Egypt. Chapter 1, Origins of the Mixed Courts, covers the build up to the reforms of 1875, and Chapter 2 deals with the Structure and Laws of the Mixed Courts, including their organisation, judiciary, and administration, and how the sovereignty of Egypt was affected. Chapter 3, the first of seven chapters dealing with the history of the courts over their lifespan, is on 1875 to 1885, which covers the first important move of the Mixed Courts-upholding the law against the Khedive, thus showing that even the ruler of Egypt was subject to the law. The British Occupation in 1882, and the establishment of the reformed Native Courts in 1883 are also discussed. 1886 to 1895 sees the Mixed Courts in a more active role, assuming jurisdiction over large companies and institutions. The theory of Government Immunity begins to develop, and this appears again in Chapter 5, 1896 to 1905, in considering the Dongola Expedition. Taxation, Trademarks, Personal Status and General Jurisprudence are all considered. Chapter 6, 1906 to 1915, introduces further cases on Taxation and Company Law, as well as on the definition of foreigners. The 1st. World War is discussed, as is the arrangement of binding precedent from a plenary session of the Mixed Court of Appeal, to resolve disputes within the Mixed Courts. 1916 to 1925 is discussed against the background of rapid political change in Egypt's status, and 1926 to 1937 considers the general work of the Mixed Courts as well as the Salem Claim, a dispute between the USA and Egypt over the Mixed Courts. 1937 was a landmark year, and the Montreux Convention and its effects is considered. 1937 to 1949 sees the closure of the Mixed Courts, the transfer of functions to the new National Courts, and a series of important judgements on the Jurisdictional Immunity of Foreign Armed Forces in Egypt.
title: Statutory Control of Land and the Administration of Agrarian Policies in Malawi: An Historical Study of the Role of Legislation in the Administration of Agrarian Change, From the Colonial to the Post-Colonial Period.

Year: 1983

description: This thesis traces the evolution of agrarian legislation in Malawi in response to some of the main currents in academic descriptions of the country's agricultural history. In some of the notable studies, prominence has been given to the centrality of colonial land and labour legislation and policies in the "underdevelopment" of agriculture and the general exploitation of peasant communities. This unfortunately obscures the role of legislation on crop marketing, which was just as voluminous as land and labour legislation, and other colonial policies on related issues like the allocation of agricultural credit. By focusing on the whole gamut of agrarian laws and policies, one part of this thesis attempts to present a more complete review of the colonial agricultural economy. The second part reviews the post-colonial agricultural economy and shifts the debate from colonialism and underdevelopment to post-colonial efforts to transform peasant agriculture using, among other tools, statutory enactments. Unlike other East and Central African countries, the post-colo- nial agricultural economy of Malawi has only belatedly begun to receive academic attention, and one of the general aims of this study is to contribute to the growing literature on the subject. Although the thesis responds to some of the trends in the historiography of agriculture in Malawi, it also aspires to contribute to legal scholarship. It is primarily a study of how legislation, the substance of a legal discipline, can be promulgated to serve varying and conflicting interests in an agricultural economy. The historical and socio-legal dimensions provide the necessary information for a critical appraisal of some of the assertions made by lawyers on the importance of law as an instrument for social change.
title: Labour Market Institutions in Indian Industry: A Comparison of Mumbai and Kolkata.
Creators: name: Miyamura, Satoshi
Publisher: name: School of Oriental and African Studies, University of London
Year: 2010

description: The thesis examines labour-management relations in Indian industries to provide an alternative analysis of labour market reform priorities. It argues that labour market institutions (LMIs) reflect the balance of power at the macro level, and in turn affect the historically specific ways in which industrial development proceeded in India. Using a combination of micro level data collected from field research in Mumbai (Bombay) and Kolkata (Calcutta), complemented by secondary evidence on the wider social and historical context, the reproduction and transformation of different types of LMIs are explained in terms of their location within changing patron-client politics. The thesis challenges the common argument that industrial performance in Mumbai was better because it enjoyed professional company-based unions compared to unions organised at industry' level and affiliated to political parties in Kolkata. Our interpretation is that the causality is at least partially in the opposite direction, with dynamic regions providing strong incentives for unions to organise to seek company based 'rents' rather than political rents that are more attractive in less industrially dynamic regions. This approach contrasts with some mainstream theories that focus on informational and transaction costs and policy failures as the main determinants of LMIs. We also examine how the labour process is managed under different types of LMIs. We establish the importance of different types of macro political conflicts in shaping the opportunities, incentives and constraints of micro bargaining agents. The mode of bargaining in the LIVIIs is also shown to be affected by the bargaining powers of other actors in the wider social context in which labour-management bargaining takes place. Many mainstream models that inform policy assume that LMIs precede growth and misleadingly treat them as 'exogenous' variables. An important implication of the thesis is that LMIs are 'endogenous' variables and therefore a broader set of reforms are required for sustaining economic growth.

description: Elastic $S-$wave scattering of a charm meson with a light pseudoscalar meson in $J^P =0^+$ is investigated in the flavour $\bar{\mathbf{3}}$, $\mathbf{6}$ and $\overline{\mathbf{15}}$ sectors at the $SU(3)_f$ flavour point using lattice QCD, working on three volumes with $m_π \approx 700$ MeV. Large bases of interpolating operators are employed to extract finite-volume spectra, which are subsequently used with the Lüscher method to provide constraints on infinite-volume scattering amplitudes. Examining the singularities of the amplitudes, the $S-$wave amplitude in the flavour $\bar{\mathbf{3}}$ sector is found to contain a deeply bound state, strongly coupled to elastic threshold, corresponding to the $J^P = 0^+$ $D_{s0}^*(2317)$. In the exotic flavour $\mathbf{6}$ sector a virtual bound state is found at $\sqrt{s_{\rm{pole}}} = 2510 - 2610$ MeV, roughly $40-140$ MeV below threshold, whereas the $\overline{\mathbf{15}}$ channel shows weak repulsion.

description: A key part of First Person Shooter network gaming is the game server discovery phase. Whilst probing for suitable servers from a wireless network, a large burst of network traffic is generated, potentially leading to detrimental effects on network capacity available to other wireless users. This can be minimised using an optimised algorithm to order the discovery probes and subsequently terminate the discovery process early. In this paper we explore further modifications to a previously proposed algorithm and examine its efficacy in further reducing the probe time/traffic during the server discovery phase. We show that it is possible to further reduce the overall discovery process duration by up to 13% while still presenting all suitable servers to the user for selection.

description: Quantum circuit synthesis describes the process of converting arbitrary unitary operations into a gate sequence of a fixed universal gate set, usually defined by the operations native to a given hardware platform. Most current synthesis algorithms are designed to synthesize towards a set of single qubit rotations and an additional entangling two qubit gate, such as CX, CZ, or the Molmer Sorensen gate. However, with the emergence of neutral atom based hardware and their native support for gates with more than two qubits, synthesis approaches tailored to these new gate sets become necessary. In this work, we present an approach to synthesize multi controlled phase gates using ZX calculus. By representing quantum circuits as graph like ZX diagrams, one can utilize the distinct graph structure of diagonal gates to identify multi controlled phase gates inherently present in some quantum circuits even if none were explicitly defined in the original circuit. We evaluate the approach on a wide range of benchmark circuits and compare them to the standard Qiskit synthesis regarding its circuit execution time for neutral atom based hardware with native support of multi controlled gates. Our results show possible advantages for current state of the art hardware and represent the first exact synthesis algorithm supporting arbitrary sized multi controlled phase gates.

description: We present the evolution of the electronic structure of CrSBr from its antiferromagnetic ground state to the paramagnetic phase above T_N=132 K, in both experiment and theory. Low temperature angle-resolved photoemission spectroscopy (ARPES) results are obtained using a novel method to overcome sample charging issues, revealing quasi-2D valence bands in the ground state. The results are very well reproduced by our QSGŴ calculations, which further identify certain bands at the X points to be exchange-split pairs of states with mainly Br and S character. By tracing band positions as a function of temperature, we show the splitting disappears above T_N. The energy splitting is interpreted as an effective exchange splitting in individual layers in which the Cr moments all align, within the so-called A-type antiferromagnetic arrangement. Our results lay firm foundations for the interpretation of the many other intriguing physical and optical properties of CrSBr.

Procedurally Optimised ZX-Diagram Cutting for Efficient T-Decomposition in Classical Simulation

description: A quantum circuit may be strongly classically simulated with the aid of ZX-calculus by decomposing its $t$ T-gates into a sum of $2^{αt}$ classically computable stabiliser terms. In this paper, we introduce a general procedure to find an optimal pattern of vertex cuts in a ZX-diagram to maximise its T-count reduction at the cost of the fewest cuts. Rather than reducing a Clifford+T diagram based on a fixed routine of decomposing its T-gates directly (as is the conventional approach), we focus instead on taking advantage of certain patterns and structures common to such circuits to, in effect, design by automatic procedure an arrangement of spider decompositions that is optimised for the particular circuit. In short, this works by assigning weights to vertices based on how many T-like gates they are blocking from fusing/cancelling and then appropriately propagating these weights through any neighbours which are then blocking weighted vertices from fusing, and so on. Ultimately, this then provides a set of weightings on relevant nodes, which can then each be cut, starting from the highest weighted down. While this is a heuristic approach, we show that, for circuits small enough to verify, this method achieves the most optimal set of cuts possible $71\%$ of the time. Furthermore, there is no upper bound for the efficiency achieved by this method, allowing, in principle, an effective decomposition efficiency $α\rightarrow0$ for highly structured circuits. Even applied to random pseudo-structured circuits (produced from CNOTs, phase gates, and Toffolis), we record the number of stabiliser terms required to reduce all T-gates, via our method as compared to that of the more conventional T-decomposition approaches (namely \cite{kissinger21}, with $α\approx0.47$), and show consistent improvements of orders of magnitude, with an effective efficiency $0.1\lesssimα\lesssim0.2$.

description: Optimal behaviours of a system to perform a specific task can be achieved by leveraging the coupling between trajectory optimization, stabilization, and design optimization. This approach is particularly advantageous for underactuated systems, which are systems that have fewer actuators than degrees of freedom and thus require for more elaborate control systems. This paper proposes a novel co-design algorithm, namely Robust Trajectory Control with Design optimization (RTC-D). An inner optimization layer (RTC) simultaneously performs direct transcription (DIRTRAN) to find a nominal trajectory while computing optimal hyperparameters for a stabilizing time-varying linear quadratic regulator (TVLQR). RTC-D augments RTC with a design optimization layer, maximizing the system's robustness through a time-varying Lyapunov-based region of attraction (ROA) analysis. This analysis provides a formal guarantee of stability for a set of off-nominal states. The proposed algorithm has been tested on two different underactuated systems: the torque-limited simple pendulum and the cart-pole. Extensive simulations of off-nominal initial conditions demonstrate improved robustness, while real-system experiments show increased insensitivity to torque disturbances.

SU($\boldsymbol N$) Kondo-Heisenberg chain: Phase diagram, Ising criticality, and the coexistence of heavy quasiparticles and valence bond solid order

description: We map out the ground state phase diagram of a one-dimensional SU($N$) Kondo-Heisenberg lattice model at half filling and in the fully antisymmetric self-adjoint representation as a function of $\tfrac {1}{N}$ and Kondo coupling $J_k/t$. On the basis of auxiliary field quantum Monte Carlo (QMC) simulations with even $N$ up to 8, we show that the enlarged SU($N\ge 4$) symmetry realizes a quantum phase transition separating a valence bond solid (VBS) phase occupying a weak coupling part of the phase diagram and the Kondo insulator (KI) state dominating in the strong $J_k/t$ limit. Along the phase boundary, we always observe critical exponents that belong to a two-dimensional classical Ising universality class. We next trace the evolution of the composite fermion and spin spectral functions across the phase boundary and conclude that VBS order triggers a bond order wave state of conduction electrons, both coexisting with Kondo screening. Upon further reducing $J_k/t$ we observe that composite quasiparticles lose their spectral weight indicating that VBS order gradually liberates localized $f$ spins from forming Kondo singlets with conduction electron spins. We contrast the QMC results with a static large-$N$ approximation, and we show that in the limit of infinite degeneracy $N\to\infty$ the order-disorder transition becomes of first order and is accompanied by a full decoupling of conduction electrons and localized $f$ spins. We complete our analysis by considering the limit of a vanishing Heisenberg coupling $J_h=0$, and we provide evidence that the enlarged SU($N$) symmetry and low dimensionality of the RKKY exchange interaction are not sufficient to induce VBS order in the conventional SU($N$) Kondo chain which hosts solely a KI phase.

title: Portuguese Law and Administration in Mozambique and Their Effect on the Customary Land Laws of Three Tribes of the Lake Nyasa Region.

description: The study that follows has two purposes. The first is to show how the present statutory land law in Mozambique evolved out of previous experiences in other parts of the Portuguese world: in what way the perpetual leaseholds which now constitute the main form of European land tenure closely resemble the former prazos; how the prazos can he traced back to an agrarian contract known to mediaeval Portugal and indeed to ancient Greece and Rome; and, finally, how the feudal system of granting powers of sovereignty to certain noblemen (donatarios), practised since the early l5th Century in the Portuguese islands of the Atlantic and, later, in Brazil and Angola, contributed to the prazo system. In the second place this study is concerned with an analysis of the impact produced by Portuguese law and administration on the customary land laws of three tribes of the north of Mozambique. For reasons discussed throughout the work and summarised in the final chapter, changes produced on customary land law were only minimal.

description: Compact, high-precision inertial sensors are needed to isolate many modern physics experiments from disturbances caused by seismic motion. We present a novel inertial sensor whose mechanical oscillator fits on a standard one-inch diameter optic. The oscillators achieve a Quality factor of over 600,000 and a resonance frequency of 50\,Hz, giving them a suspension thermal noise floor lower than all commercially available inertial sensors. The oscillator is combined with a Pound-Drever-Hall based readout scheme that achieves a displacement noise of 100\,f\msqrthz above 0.2\,Hz. We integrate the oscillator and readout to make two inertial sensors. Of order n$g$ performance is achieved in a broad band from 0.1\,Hz to 200\,Hz. Below 20\,Hz, the sensor presented here offers comparable performance to the best inertial sensors available today while being a fraction of the size. Above 20\,Hz, the sensor is, to the author's knowledge, the best demonstrated in the literature to date for a device of this style, with a self-noise floor of 0.1\,n$g$\sqrthz. The excellent performance of the sensors across the relevant seismic frequencies, vacuum compatibility, and compact size make it a prime candidate for integration into sophisticated seismic isolation schemes, such as those used by gravitational wave detectors.

title: The Crisis of Objectivity in Anthropology: A Consideration Through Romanticism and Surrealism.
Creators: name: Richardson, Michael
Publisher: name: School of Oriental and African Studies, University of London
Year: 1991

description: One of the central concerns in recent anthropological theory has been the status of objectivity. In the influential writing of James Clifford, it is argued that anthropology needs to recognise that it can only establish 'partial truths' and that holistic and integrated disciplinary approaches are untenable. The re-evaluation of the subjective brings any concept of objectivity into question. Clifford's work has had such an influence that it suggests a generalised crisis is perceived in relation to how anthropological conceptions of objectivity have been established. The thesis will consider this question by looking back to aspects of the romantic tradition. It will especially consider surrealism in anthropological perspective and will question the way in which Clifford has founded his subjectivism in his understanding of surrealism. It will be argued that surrealism sought its own standard of objectivity which issued out of romanticism and needs to be considered in such historical perspective. It will be further argued that romantic concepts of objectivity have been systematically distorted by positivism, something which has had important consequences for the history of anthropology. This was particularly so in that romanticism provided anthropology with a methodological tool, in the concept of empathy, against which positivist and empiricist inductive methodologies based on intensive fieldwork have reacted. This entails a re-consideration of the nature of anthropological evidence and its effects, particularly in the way we construct images of other people. The aim will be to show that it is only through an understanding of the process of reciprocity that takes account not only of the nature of otherness but also our notions of the familiar that a genuine anthropological objectivity can be established. It will be argued that the current idea of a reflexive anthropology is inadequate to engage with all the implications of such an approach.
