description: We present first, encouraging results obtained with an experimental apparatus based on Coherent Population Trapping and aimed at detecting biological (cardiac) magnetic field in magnetically compensated, but unshielded volume. The work includes magnetic-field and magnetic-field-gradient compensation and uses differential detection for cancellation of (common mode) magnetic noise. Synchronous data acquisition with a reference (electro-cardiographic or pulse-oximetric) signal allows for improving the S/N in an off-line averaging. The set-up has the relevant advantages of working at room temperature with a small-size head, and of allowing for fast adjustments of the dc bias magnetic field, which results in making the sensor suitable for detecting the bio-magnetic signal at any orientation with respect to the heart axis and in any position around the patient chest, which is not the case with other kinds of magnetometers.

description: We propose to revisit the diffusion of atoms in the Knudsen regime in terms of a complex dynamical reflection process. By means of molecular dynamics simulation we emphasize the asymptotic nature of the cosine law of reflection at the atomic scale, and carefully analyze the resulting strong correlations in the reflection events. A dynamical interpretation of the accomodation coefficient associated to the slip at the wall interface is also proposed. Finally, we show that the first two moments of the stochastic process of reflection non uniformly depend on the incident angle.

description: We theoretically investigate how entangled atomic states generated via spin-changing collisions in a spinor Bose-Einstein condensate can be designed and controllably prepared for atom interferometry that is robust against common technical issues, such as limited detector resolution. We use analytic and numerical treatments of the spin-changing collision process to demonstrate that triggering the entangling collisions with a small classical seed rather than vacuum fluctuations leads to a more robust and superior sensitivity when technical noise is accounted for, despite the generated atomic state ideally featuring less metrologically useful entanglement. Our results are relevant for understanding how entangled atomic states are best designed and generated for use in quantum-enhanced matter-wave interferometry.

description: This is a blog post published by the Department of War Studies, King's College London.
The use of intelligence is always considered crucial during times of crisis and war. British intelligence collection and assessments on the Dardanelles during the 1906 crisis in Taba, Egypt and its aftermath, presents a good case. Taba demonstrates how intelligence was successfully used during a Near Eastern crisis and how assessments on the Dardanelles impacted the government’s decision-making about the advisability of forcing the Straits in times of conflicts.
The impact of computed tomography on the utilization of neurological tests at a community hospital

Publisher: name: University of British Columbia

description: One of the major issues in the health care industry is the continual rise in total health care expenditures relative to the Gross National Product. A significant portion of this rise has been attributed to the increasing use of medical technologies. As an increasing number of technological innovations are being developed for health care, and such new technologies are often complicated and expensive, the need for properly conducted evaluative studies becomes very important. It is essential to know whether a new technology is a substitute for less effective ones or is merely an add-on. Clear guidelines on under what conditions the new technology is applicable should be developed. For a diagnostic technology, the ideal model of evaluation should involve assessments of technical capability and safety, diagnostic accuracy, diagnostic impact, therapeutic impact, patient outcome, economic impact and availability. In the relatively short period since 1971, when computed tomography (CT) was first used clinically, it has become an important part of medical practice. This study attempts to assess the impact of CT on the utilization of related neurological tests at the Lions Gate Hospital. This is a community hospital serving a population of approximately 140,000 people. This study is a retrospective, before-after comparison of the utilization of neurological tests before and after the introduction of CT. Two groups of neurological patients, who were hospitalized during the study period 1973 to 1983/4, were assessed. These were the brain tumour group (ICD-9: 191, 198 and 225) and the cerebrovascular disease group (ICD-9: 430 to 438). The results of this study suggest that, for both groups of patients, CT is a complete replacement for pneumoencephalography and nuclear brain scanning, and is a partial replacement for electroencephalography and plain skull radiography. However, CT has had little impact on cerebral angiography which fell marginally in the brain tumour group and rose significantly in the cerebrovascular disease group. It has also been estimated that, over the study period, the average total cost of neurological tests (based on 1983/4 fee-dollars), on a per patient basis, remained the same for the brain tumour group but rose by 92% for the cerebrovascular disease group.

description: Node injection attack on Graph Neural Networks (GNNs) is an emerging and practical attack scenario that the attacker injects malicious nodes rather than modifying original nodes or edges to affect the performance of GNNs. However, existing node injection attacks ignore extremely limited scenarios, namely the injected nodes might be excessive such that they may be perceptible to the target GNN. In this paper, we focus on an extremely limited scenario of single node injection evasion attack, i.e., the attacker is only allowed to inject one single node during the test phase to hurt GNN's performance. The discreteness of network structure and the coupling effect between network structure and node features bring great challenges to this extremely limited scenario. We first propose an optimization-based method to explore the performance upper bound of single node injection evasion attack. Experimental results show that 100%, 98.60%, and 94.98% nodes on three public datasets are successfully attacked even when only injecting one node with one edge, confirming the feasibility of single node injection evasion attack. However, such an optimization-based method needs to be re-optimized for each attack, which is computationally unbearable. To solve the dilemma, we further propose a Generalizable Node Injection Attack model, namely G-NIA, to improve the attack efficiency while ensuring the attack performance. Experiments are conducted across three well-known GNNs. Our proposed G-NIA significantly outperforms state-of-the-art baselines and is 500 times faster than the optimization-based method when inferring.

description: This paper addresses the workspace analysis of the orthoglide, a 3-DOF parallel mechanism designed for machining applications. This machine features three fixed parallel linear joints which are mounted orthogonally and a mobile platform which moves in the Cartesian x-y-z space with fixed orientation. The workspace analysis is conducted on the bases of prescribed kinetostatic performances. The interesting features of the orthoglide are a regular Cartesian workspace shape, uniform performances in all directions and good compactness. Interval analysis based methods for computing the dextrous workspace and the largest cube enclosed in this workspace are presented.

description: The axial-vector Ward-Takahashi identity is used to derive mass formulae for neutral pseudoscalar mesons. Flavour symmetry breaking entails non-ideal flavour content for these states. Adding that the η^\prime is not a Goldstone mode, exact chiral-limit relations are developed from the identity. They connect the dressed-quark propagator to the topological susceptibility. It is confirmed that in the chiral limit the η^\prime mass is proportional to the matrix element which connects this state to the vacuum via the topological susceptibility. The implications of the mass formulae are illustrated using an elementary dynamical model, which includes an Ansatz for that part of the Bethe-Salpeter kernel related to the non-Abelian anomaly. In addition to the current-quark masses, the model involves two parameters, one of which is a mass-scale. It is employed in an analysis of pseudoscalar- and vector-meson bound-states. While the effects of SU(N_f=2) and SU(N_f=3) flavour symmetry breaking are emphasised, the five-flavour spectra are described. Despite its simplicity, the model is elucidative and phenomenologically efficacious; e.g., it predicts η-η^\prime mixing angles of ~ (-15 degrees) and π^0-ηangles of ~ 1 degree.

Visual Images Of Madness And Insanity In European Artistic Traditions From The Seventeenth To The Eighteenth Century
Creators: name: Couloute, Janet
Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: Assuming an interdisciplinary approach that acknowledges the synergetic relationship between art history, and the history of medicine and madness, this thesis argues that visual representations of madness and distraction have both reflective and constitutive qualities and are therefore adept at illuminating histories of madness. By closely analysing seventeenth and eighteenth-century iconographic representations of madness, in conjunction with the active presence of the male artist in the form of artistic conventions, subject matter, and critique, scholarly wisdoms are challenged. These include, the static history of seventeenth-century madness, humoural theory’s paradigmatic significance beyond Galenic medicine, aetiologies of female madness solely conceptualised as uterine disorder, and the limited relevance of race in the written European histories of madness. Given the manifest intentions of the artist, pitted against the multifarious and unintended impact of the imagery on the viewer, an iconological approach was adopted that enabled a close engagement with the art work, and the cultural context of their creation in order to go beyond assumptions or tropes made about the artistic process, and implicit beholders at the time of their production.Beginning with an introductory chapter that affords the reader an understanding of the important underpinning popular, and learned discourses on madness and its management, four distinct but closely aligned chapters make up the main body of the thesis. Chapters Two and Three span the seventeenth-century and evidence the artist’s ability to utilise humourism’s essential materiality and ability to externalise madness’ internal manifestations, by using familiar tropes such as the stupidity of the lower classes, the unorthodoxy of the charlatan, and the inherently flawed female body. Chapter Four and Five introduces the eighteenth-century sensible and innervated body informing imagery that provokes a more active engagement from the viewer, either as an exemplum virtutis or voyeur. Chapter Six, concludes by offering a number insights garnered from the above analysis, and forges links with the modern eras preoccupation with abolition, race, and representation. Each chapter is used as a case study that challenges the histories of madness from which the works emerge, and offers new insights into the art and cultural scholarship accompanying the imagery.

description: This paper presents the development of a new software in order to manage objects, robots and mannequins in using the possibilities given by the haptic feedback of the Phantom desktop devices. The haptic device provides 6 positional degree of freedom sensing but three degrees force feedback. This software called eM-Virtual Desktop is integrated in the Tecnomatix's solution called eM-Workplace. The eM-Workplace provides powerful solutions for planning and designing of complex assembly facilities, lines and workplaces. In the digital mockup context, the haptic interfaces can be used to reduce the development cycle of products. Three different loops are used to manage the graphic, the collision detection and the haptic feedback according to theirs own frequencies. The developed software is currently tested in industrial context by a European automotive constructor.

Molecular gas in high-velocity clouds: revisited scenario

description: We report a new search for 12CO(1-0) emission in high-velocity clouds (HVCs) performed with the IRAM 30 m telescope. This search was motivated by the recent detection of cold dust emission in the HVCs of Complex C. Despite a spatial resolution which is three times better and sensitivity twice as good compared to previous studies, no CO emission is detected in the HVCs of Complex C down to a best 5 sigma limit of 0.16 K km/s at a 22'' resolution. The CO emission non-detection does not provide any evidence in favor of large amounts of molecular gas in these HVCs and hence in favor of the infrared findings. We discuss different configurations which, however, allow us to reconcile the negative CO result with the presence of molecular gas and cold dust emission. H2 column densities higher than our detection limit, N(H2) = 3x10^{19} cm^{-2}, are expected to be confined in very small and dense clumps with 20 times smaller sizes than the 0.5 pc clumps resolved in our observations according to the results obtained in cirrus clouds, and might thus still be highly diluted. As a consequence, the inter-clump gas at the 1 pc scale has a volume density lower than 20 cm^{-3} and already appears as too diffuse to excite the CO molecules. The observed physical conditions in the HVCs of Complex C also play an important role against CO emission detection. It has been shown that the CO-to-H2 conversion factor in low metallicity media is 60 times higher than at the solar metallicity, leading for a given H2 column density to a 60 times weaker integrated CO intensity. And the very low dust temperature estimated in these HVCs implies the possible presence of gas cold enough (< 20 K) to cause CO condensation onto dust grains under interstellar medium pressure conditions and thus CO depletion in gas-phase observations.

description: Research on innovation and sustainability is prolific but fragmented. This study integrates the research on innovation in management and business and STEM fields for sustainability in a unified framework for the case of developing countries (i.e., the Global South). It presents and discusses the output, impact, and structure of such research based on a sample of 14,000+ articles and conference proceedings extracted from the bibliographic database Scopus. The findings reveal research output inflections after global announcements such as UN-Earth Summits. The study also reveals the indisputable leadership of China in overall output and research agenda-setting. Nonetheless, countries such as India, Mexico, and Nigeria are either more efficient or impactful. GS research published in highly reputable journals is still scarce but increasing modestly. Central topic clusters (e.g., knowledge management) remain peripheral to the global Sustainable Development Goals (SDGs) research landscape. Finally, academic-corporate collaboration is in its infancy and limited to particular economic sectors: energy, pharmaceuticals, and high-tech.

description: We study chromospheric emission to understand the temperature stratification in the solar chromosphere. We observed the intensity profile of the CaIIH line in a quiet Sun region close to the disk center at the German Vacuum Tower Telescope. We analyze over 10^5 line profiles from inter-network regions. For comparison with the observed profiles, we synthesize spectra for a variety of model atmospheres with a non local thermodynamic equilibrium (NLTE) radiative transfer code. A fraction of about 25% of the observed CaIIH line profiles do not show a measurable emission peak in H_{2v} and H_{2r} wavelength bands (reversal-free). All of the chosen model atmospheres with a temperature rise fail to reproduce such profiles. On the other hand, the synthetic calcium profile of a model atmosphere that has a monotonic decline of the temperature with height shows a reversal-free profile that has much lower intensities than any observed line profile. The observed reversal-free profiles indicate the existence of cool patches in the interior of chromospheric network cells, at least for short time intervals. Our finding is not only in conflict with a full-time hot chromosphere, but also with a very cool chromosphere as found in some dynamic simulations.

description: In general the kernel of QCD's gap equation possesses a domain of analyticity upon which the equation's solution at nonzero chemical potential is simply obtained from the in-vacuum result through analytic continuation. On this domain the single-quark number- and scalar-density distribution functions are mu-independent. This is illustrated via two models for the gap equation's kernel. The models are alike in concentrating support in the infrared. They differ in the form of the vertex but qualitatively the results are largely insensitive to the Ansatz. In vacuum both models realise chiral symmetry in the Nambu-Goldstone mode and in the chiral limit, with increasing chemical potential, exhibit a first-order chiral symmetry restoring transition at mu~M(0), where M(p^2) is the dressed-quark mass function. There is evidence to suggest that any associated deconfinement transition is coincident and also of first-order.

description: © 2019 Elsevier B.V. The increases in CO 2 concentration and attendant temperature are likely to impact agricultural production. This study investigated the effects of elevated temperature alone and in combination with CO 2 enrichment on grain yield and quality of soybean (Glycine max) and maize (Zea mays) grown in a Mollisol over five-year growing seasons. Plants were grown in open-top chambers with the ambient control, 2.1 °C increase in air temperature (eT) and eT together with 700 ppm atmospheric CO 2 concentration (eTeCO 2 ). While eTeCO 2 but not eT increased the mean grain yield of soybean by 31%, eTeCO 2 and eT increased the yield of maize similarly by around 25% compared to the ambient control. Furthermore, eT and eTeCO 2 did not significantly affect grain protein of either species but consistently increased oil concentrations in grains of both species with eTeCO 2 increasing more. The eT increased grain Fe concentration relative to the control treatment but decreased Ca concentration, while the relative concentrations of P, K, Mn and Zn varied with crop species. The elevated CO 2 enlarged the eT effect on Fe concentration, but decreased the effect on Ca concentration. The results suggest that crop selection is important to maximize yield benefits and to maintain grain quality to cope with elevated CO 2 and temperature of future climate change in this temperate region where the temperature is near or below the optimal temperature for crop production.

The analysis takes place in the context of $SU(5)\times U(1)'$ GUT embedded in an $E_8$ covering group which is associated with the (highest) geometric singularity of the elliptic fibration. In this context, the $U(1)'$ is a linear combination of four abelian factors subjected to appropriate anomaly cancellation conditions. Furthermore, we require universal $U(1)'$ charges for the three chiral families and different ones for the corresponding fields of the vector-like representations. Under the aforementioned assumptions, we find 192 such models which can be classified into five distinct categories with respect to their specific GUT properties. We exhibit representative examples for each such class and construct the superpotential couplings and the fermion mass matrices. We explore the implications of the vector-like states in low energy phenomenology including the predictions regarding the B-meson anomalies. The rôle of R-parity violating terms appearing in some particular models of the above construction is also discussed.

description: We analyze in detail the size of next-to-leading order corrections to hard exclusive meson production within the collinear factorization approach. Corrections to the cross section are found to be huge at small xB and substantial in typical fixed-target kinematics. With the models we take for nucleon helicity-flip distributions, the transverse target polarization asymmetry in vector meson production is strongly affected by radiative corrections, except at large xB. Its overall size is very small for rho production but can be large in the omega channel.

description: ATIS (Advanced Traveller Information Systems) are aimed to dispatch information on traffic conditions to travellers allowing them to keep their travel decisions with less uncertainty. Effects of ATIS can be analysed at a disaggregated level or at a network level. In the first case the impacts of ATIS on individual decisions are considered, in the second case it is considered how travellers’ decisions interact each other and with the congestion phenomenon, leading to actual traffic patterns. The investigation of the effects of information on travellers’ behaviours/choices at a disaggregated/individual level is the focus of this work, provided that it is a pre-requisite for any analysis of the impacts on traffic networks.
One of the crucial points in ATIS is that travellers’ behaviour is expected to be influenced by the ability of the system in making accurate estimations of actual travel times. In particular, this work investigates the effect of the information accuracy on travellers’ compliance and proposes an original modelling framework able to explicitly estimate it.
The study is carried out by means of an experimental environment based on a  Stated Preference survey. The obtained results are very encouraging and allow for a deeper comprehension and simulation of travellers’ compliance with ATIS.

I sistemi ATIS (Advanced Traveller Information Systems) hanno come principale obiettivo quello di informare i viaggiatori sulle condizioni di traffico affinché essi possano effettuare le proprie scelte di viaggio con maggiore consapevolezza. Gli effetti degli ATIS possono essere analizzati a due diversi livelli: un livello disaggregato, al quale si osserva l’effetto che l’informazione ha sulle scelte di un dato viaggiatore, e ad un livello di rete, al quale si osserva l’effetto dell’interazione fra le scelte dei singoli utenti e fra queste ed il fenomeno della congestione. Questo studio si pone al livello di analisi disaggregato, premessa per qualsiasi operazione di valutazione dei sistemi ATSI a livello di rete. In particolare, l’obiettivo del lavoro è di effettuare un’analisi dell’effetto dell’accuratezza di un sistema ATIS sull’adeguamento delle scelte dei viaggiatori all’informazione ricevuta (compliance). In tale ambito, lo studio è stato effettuato a partire da una serie di dati raccolti mediante una indagine del tipo Preferenze Dichiarate (Stated Preferences- SP). I risultati ottenuti sono particolarmente significativi ed hanno permesso la specificazione e calibrazione di un modello in grado di simulare in maniera esplicita l’effetto delle caratteristiche dei servizi ATIS sulla compliance dei viaggiatori. I risultati aprono il campo all’utilizzo, all’interno di strumenti di assegnazione per contesti ATIS, della variabile di compliance non più in forma parametrica, come ad oggi generalmente fatto, ma in forma di variabile endogena.

description: TAZ (Transcriptional coActivator with PDZ binding motif) è un coattivatore trascrizionale che negli ultimi anni è stato descritto come interattore di diversi fattori di trascrizione, tra cui Runx2, PPARgamma, TBX5, TEADs. Durante lo svolgimento del mio progetto di dottorato, abbiamo dimostrato che, nel modello sperimentale delle cellule tiroidee differenziate, TAZ interagisce in vitro ed in vivo con i fattori di trascrizione Pax8 e TTF-1 e che questa interazione incrementa notevolmente la loro capacità di attivare la trascrizione. Alla luce di questi dati abbiamo iniziato l’analisi del fenotipo del topo TAZ-/-. Sfortunatamente il fenotipo del knock-out è risultato essere letale prima di E15.5 quindi, per cercare di ottenere topi knock-out stiamo attualmente effettuando incroci per trasportare il knock-out dal ceppo sv129 a quello c57Bl6 sperando che in un ceppo differente il fenotipo sia meno severo. Nel frattempo, abbiamo iniziato a studiare il ruolo di TAZ in zebrafish (Danio rerio). TAZ è espresso nella tiroide dello zebrafish a partire dalle 48 hpf (hours post fertilization) e, a questo stadio, risulta essere espresso anche nella pinna, nella lente, nella notocorda, nel dotto pronefrico, negli archi faringei e nella vescicola otica. Gli embrioni microiniettati con il morfolino contro TAZ a 48 hpf mostrano un fenotipo alterato rispetto al wild-type e sono caratterizzati dalla curvatura del tronco e dalla testa più piccola e dalla forma anomala. La tiroide nei morfanti risulta correttamente differenziata, tuttavia i follicoli tiroidei sono disposti in maniera alterata, verosimilmente a causa dell’anormale sviluppo dei vasi sanguigni nella testa e dell’assenza sia di osteogenesi che di condrogenesi. E’ ragionevole ipotizzare che un non corretto sviluppo dei vasi potrebbe essere la causa della mortalità embrionale osservata nel topo dato che quest’ultimo, a differenza di zebrafish, non può sopravvivere senza una corretta architettura vascolare. In conclusione, in zebrafish la mancanza di TAZ provoca un’alterata formazione della ghiandola tiroidea, effetto che tuttavia appare secondario ad un parziale sviluppo del sistema vascolare. E’ auspicabile che in futuro l’analisi del topo potrà fornire ulteriori indicazioni sul ruolo di questo coattivatore nel differenziamento tiroideo.

description: Scopo della ricerca svolta è la valutazione della normativa della Comunità Europea per le imbarcazioni da diporto (25/94 CE) realizzate in materiali compositi. Per la valutazione si è fatto riferimento sua alle implicazioni tecnologiche sia a quelle economiche. Il principale strumento utilizzato per la valutazione è stata l’analisi strutturale, condotta con il metodo degli elementi finiti, applicata a strutture semplici e composte come telai e zone delle imbarcazioni con confini e carichi tali da determinare condizioni tensionali significative. Per lo studio si sono prese in considerazione le imbarcazioni a sostentamento idrodinamico significativo (non trascurabile).
Mean-field equations for weakly nonlinear two-scale perturbations of forced hydromagnetic convection in a rotating layer

description: We consider stability of regimes of hydromagnetic thermal convection in a rotating horizontal layer with free electrically conducting boundaries, to perturbations involving large spatial and temporal scales. Equations governing the evolution of weakly nonlinear mean perturbations are derived under the assumption that the alpha-effect is insignificant in the leading order (e.g., due to a symmetry of the system). The mean-field equations generalise the standard equations of hydromagnetic convection: New terms emerge -- a second-order linear operator representing the combined eddy diffusivity, and quadratic terms associated with the eddy advection. If the perturbed CHM regime is non-steady and insignificance of the alpha-effect in the system does not rely on the presence of a spatial symmetry, the combined eddy diffusivity operator also involves a non-local pseudodifferential operator. If the perturbed CHM state is almost symmetric, alpha-effect terms appear in the mean-field equations as well. Near a point of a symmetry-breaking bifurcation, cubic nonlinearity emerges in the equations. All the new terms are in general anisotropic. A method for evaluation of their coefficients is presented; it requires solution of a significantly smaller number of auxiliary problems than in a straightforward approach.

Aerodynamic Analysis of Low Reynolds Number Flows

description: An aerodynamic analysis of low-Reynolds number flows is presented. The focus is placed on the laminar separation bubbles, a peculiar phenomenon of these kind of flows. The only simulations techniques feasible to be applied to complex configurations appear to be the methods based on the Reynolds Averaged Navier Stokes equations. A critical point is the turbulence modelling. In fact, the turbulence models are calibrated for flows at high Reynolds number with separation in the turbulent regime. The flow over a flat plate with an imposed pressure gradient, and around the Selig-Donavan 7003 airfoil is considered. Large eddy simulations have also been performed and used as reference for the RANS results. Laminar separation bubbles have been found by the Spalart-Allmaras and the k-w SST turbulence models. The models have been used without prescribing the transition location and assuming low values of the free-stream turbulence. The main results have been achieved for the k-w SST turbulence model. This model is very reliable for transonic flows at high Reynolds number, but has shown limits when applied to low-Reynolds number flows. A modification of the model has been proposed. The modified model, named as k-w SST-LR, has provided a correct simulation of the boundary layer in the tests performed at low and high Reynolds numbers. The laminar separation bubble arising of the SD 7003 airfoil has been well captured. The accuracy of the new model is not reduced in transonic regime.
The sites and services housing strategy in relation to the land question in the developing countries : the case of Zambia

description: This thesis examines the problems and issues associated with urban housing land in the context of Sites and Sevices housing as a strategy for providing improved housing services to the urban poor in the developing countries. It addresses the inadequacies of the existing patterns of housing land tenure and methods of supplying land. Some ideas are developed on the alternative tenure arrangements and strategies for providing housing land. The ideas are based on the supposition that the potential benefits of Sites and Services housing would never be fully realized unless new forms of land tenure and strategies for providing housing land are initiated. The methods employed in this study are based upon a literature review technique with emphasis on theoretical and content analysis. Zambia is taken as a specific case study of the housing land problem in a comparative perspective with the other three member states of the Commonwealth group of nations. The analytical framework adopted is designed to explore the impact of the existing land tenure systems and land supply methods for low income housing. The principal theme centres on the long-term equity and efficiency implications for the use of urban housing land. This study has shown that the concept of Sites and Services housing is a positive strategy for redressing the housing problems of low-income households in comparison with the available alternatives such as the conventional public low cost housing. However, the shortcomings are substantive and have substantial long-term implications. The main conclusions which may be drawn from the review and analysis of the case studies are that the private freehold and leasehold land tenure systems are not appropriate for solving the housing problems of the urban poor. Similarly, 'reactive planning' or a 'disjointed incremental' approach to housing land provision is not cost effective and responsive to the high demand for low income housing. The shortcoming of the tenure systems is the tendency to promote commodity relations in land and housing, giving rise to speculation. The urban poor do not fare well under these market conditions because they tend to lose access to land and housing services in the long run. Moreover, the method of providing land does not guarantee the availability of adequate and affordable housing land in good locations. The challenge, therefore, is how to remove housing land from the speculative market and to ensure access to the urban poor. Against this background, the concepts of 'Communal Land Trust' and 'Land Bank' advanced in this study if adopted could make Sites and Services housing a meaningful strategy for housing low-income households in Zambia and other countries with similar housing problems.
