description: Представлены результаты рассмотрения магнитоэлектрического эффекта в феррит-пьезоэлектрических слоистых структурах в области ферромагнитного резонанса. Приложенное к пьезоэлектрическому слою электрическое поле приводит к деформации ферритового слоя, в результате чего в ферритовой компоненте появляется магнитная анизотропия, которая является неоднородной по толщине. В работе исследована теоретическая модель влияния внешнего электрического поля на высокочастотную магнитную восприимчивость. Рассмотрение проведено с учетом изгибных деформаций образца. Результаты моделирования изучены на примере трехслойных структур на основе феррита никеля и титаната-цирконата свинца. Показано, что внешнее электрическое поле приводит к уширению линии магнитного резонанса, величина которого определяется отношением толщин слоев структуры. Результаты работы представляют интерес с точки зрения использования в феррит-пьезоэлектрических микроволновых устройствах.

description: The following poster summarizes our exploration of the popularity and the performance of all the Gene Set Analysis (GSA) methodologies and software published during the 20 years since its inception. "Popularity" is estimated according to each paper's citation counts, while "performance" is based on a comprehensive evaluation of the validation strategies used by papers in the field, as well as the consolidated results from the existing benchmark studies. Regarding popularity, data is collected into an online open database ("GSARefDB") which allows browsing bibliographic and method-descriptive information from 503 GSA paper references; regarding performance, we introduce a repository of jupyter workflows and shiny apps for automated benchmarking of GSA methods (“GSA-BenchmarKING”). After comparing popularity versus performance, results show discrepancies between the most popular and the best performing GSA methods.
Effect of c-kit and flt-3 overexpression on primitive hematopoietic cells
Creators: name: Chu, Pak-Yan Pat
Publisher: name: University of British Columbia
Year: 2009

description: Recent studies have demonstrated that hematopoietic stem cell (HSC) self-renewal divisions in vitro are favoured by exposure of the cells to elevated levels of Steel factor (SF) or flt-3 ligand (FL). This suggested that enhanced HSC self-renewal by these cytokines might be limited by the level of expression of the corresponding c-kit or flt-3 receptors on HSCs. In this thesis, I investigated this hypothesis by examining how retroviral-mediated overexpression of either c-kit or flt-3 affects the responsiveness of hematopoietic cells to SF and FL, respectively, first in a cell line model and then in primary mouse bone marrow cells, c-kit and flt3- transduced BaF3 cells were able to proliferate in lower concentrations of SF and FL, respectively, than control-transduced cells, although evidence of high dose inhibition was also noted. In primitive mouse bone marrow cells transduced with the same c-kit ory7f-3-encoding vectors, a similar effect on short term total cell expansion in vitro was seen. This included a cytokine-specific dose sensitization of progenitor and HSC expansion without detectable effects on their subsequent commitment or differentiation. Depressed responsiveness to very high cytokine concentrations was also seen in primary transduced cells such that no significant further net amplification of the transduced HSCs could be achieved in vitro. In vivo competitive reconstitution assays were performed to determine whether the enhanced cytokine sensitivity of receptor-overexpressing HSCs would give them a growth advantage in vivo. Although continued expression of functional receptors on the in vivo generated progeny of the transduced HSCs could be clearly documented and their self-renewal shown to be intact, their behaviour in vivo could not be distinguished from control-transduced cells, even when the corresponding ligand was administered exogenously or induced endogenously. It thus appears that neither c-kit nor flt-3 receptor levels on HSCs are limiting to their capacity to self-amplify in vivo. These results suggest that other molecular interactions of HSCs with their environment may be more potent regulators of HSC self-renewal responses in vivo and need to be identified to improve HSC amplification in vitro.

description: A new class of exact solutions of Einstein's field equations with bulk viscous fluid for an LRS Bianchi type-I spacetime is obtained by using deceleration parameter as variable. The value of Hubble's constant $H_{0}$ is found to be less than one for non-flat model and is equal to 1.5 for flat model which are of the physical interest. Some physical and geometric properties of the models are also discussed.

description: Four new chromones, named harforamone A (1), harforamone B (2), harforamone C (3), and harforamone D (4), together with six known compounds (5–10) were isolated from the dichloromethane extract of the stems of Harrisonia perforata. The chemical structures of four new compounds were elucidated by spectroscopic analysis, including 1D, 2D NMR and HRESIMS data. The known compounds were identified by comparing their spectroscopic data with the previously reported data. Compounds 7 and 8 were isolated for the first time from the Rutaceae family. The in vitro cytotoxic activity against six human cancer cell lines of the tested compounds was evaluated, but none of them showed any significant activity; only perforamone C (5) showed moderate cytotoxicity against cervical cancer cell line (HeLa).

description: We investigate the role of disorder on the various topological magnonic phases present in deformed honeycomb ferromagnets. To this end, we introduce a bosonic Bott index to characterize the topology of magnon spectra in finite, disordered systems. The consistency between the Bott index and Chern number is numerically established in the clean limit. We demonstrate that topologically protected magnon edge states are robust to moderate disorder and, as anticipated, localized in the strong regime. We predict a disorder-driven topological phase transition, a magnonic analog of the "topological Anderson insulator" in electronic systems, where the disorder is responsible for the emergence of the nontrivial topology. Combining the results for the Bott index and transport properties, we show that bulk-boundary correspondence holds for disordered topological magnons. Our results open the door for research on topological magnonics as well as other bosonic excitations in finite and disordered systems.

From the point of view of frame theory, their characterization can be restated as which graphs have a representation by a tight frame. In this paper, we classify certain line graphs that are tight frame graphs and improve a previous result on the embedding of frame graphs in tight frame graphs.

description: We present a CMB large-scale polarization dataset obtained by combining WMAP Ka, Q and V with Planck 70 GHz maps. We employ the legacy frequency maps released by the WMAP and Planck collaborations and perform our own Galactic foreground mitigation technique, which relies on Planck 353 GHz for polarized dust and on Planck 30 GHz and WMAP K for polarized synchrotron. We derive a single, optimally-noise-weighted, low-residual-foreground map and the accompanying noise covariance matrix. These are shown, through $χ^2$ analysis, to be robust over an ample collection of Galactic masks. We use this dataset, along with the Planck legacy Commander temperature solution, to build a pixel-based low-resolution CMB likelihood package, whose robustness we test extensively with the aid of simulations, finding excellent consistency. Using this likelihood package alone, we constrain the optical depth to reionazation $τ=0.069^{+0.011}_{-0.012}$ at $68\%$ C.L., on 54\% of the sky. Adding the Planck high-$\ell$ temperature and polarization legacy likelihood, the Planck lensing likelihood and BAO observations we find $τ=0.0714_{-0.0096}^{+0.0087}$ in a full $Λ$CDM exploration. The latter bounds are slightly less constraining than those obtained employing \Planck\ HFI CMB data for large angle polarization, that only include EE correlations. Our bounds are based on a largely independent dataset that does include also TE correlations. They are generally well compatible with Planck HFI preferring slightly higher values of $τ$. We make the low-resolution Planck and WMAP joint dataset publicly available along with the accompanying likelihood code.

The linearized GP equation corresponds to a wave equation on a black hole background, giving quasinormal modes under some appropriate conditions. We suggest that we can know the detailed characters and corresponding geometrical information about the acoustic black hole by observing quasinormal ringdown waves in the low temperature condensed matters.

description: The great collecting area of the mirrors coupled with the high quantum efficiency of the EPIC detectors have made XMM-Newton the most sensitive X-ray observatory flown to date. This is particularly evident during slew exposures which, while giving only 15 seconds of on-source time, actually constitute a 2-10 keV survey ten times deeper than current "all-sky" catalogues. Here we report on progress towards making a catalogue of slew detections constructed from the full, 0.2-12 keV energy band and discuss the challenges associated with processing the slew data. The fast (90 degrees per hour) slew speed results in images which are smeared, by different amounts depending on the readout mode, effectively changing the form of the point spread function. The extremely low background in slew images changes the optimum source searching criteria such that searching a single image using the full energy band is seen to be more sensitive than splitting the data into discrete energy bands. False detections due to optical loading by bright stars, the wings of the PSF in very bright sources and single-frame detector flashes are considered and techniques for identifying and removing these spurious sources from the final catalogue are outlined. Finally, the attitude reconstruction of the satellite during the slewing manoeuver is complex. We discuss the implications of this on the positional accuracy of the catalogue.

description: The Reuven Ramaty High Energy Spectroscopic Solar Imager (RHESSI) uses the rotational modulation principle to observe temporally, spatially, and spectrally resolved hard X ray and gamma ray images of solar flares. In order to track the flare evolution on time scales that are commensurate with modulation, the observed count rates must be demodulated at the expense of spatial information. The present paper describes improvements of an earlier demodulation algorithm, which decomposes the observed light curves into intrinsic source variability and instrumental modulation.

Remélhetőleg a jövőben egyre több élelmiszeripari vállalkozás ismeri fel az ISO 22000 szabvány alkalmazásának előnyeit, ami ötvözi a HACCP és az ISO 9001 alkalmazását, és kifejezetten az élelmiszeripari termelésre specializált szabványként vonult be a nemzetközi szabványok közé. - It can be determined based on our investigations that the domestic poultry-processing sector fulfils both domestic and EU regulations and requirements. Conformity with food security regulations is a priority in all affected businesses. Companies also utilise additional methods to achieve and fulfil high quality standards, such as integrated management control systems; however, these endeavours are not motivated by their internal requirements, but by the market. It is to be hoped that in the future increasing numbers of food industry businesses will acknowledge the advantages of utilising the ISO 22000 standard, which combines the HACCP and the ISO 9001 standards and was entered among international standards as one specifically relating to food industry production.

description: Human migration due to political upheaval is rapidly accelerating, yet scholarly attention to refugees' visual news representations has lagged. Using a visual analysis informed by the transnational writings of Yuval-Davis related to the politics of belonging and the peace/conflict frame literature, 811 images primarily depicting migration from Turkey into Europe in 2015 and submitted to the Pictures of the Year International competition were examined. Analysis determined that, despite billions of dollars in aid and millions of migrants who have benefited from food assistance and other development opportunities, the photographers overwhelmingly highlighted the migrants' transitory nature, vulnerability and differences while minimizing any attempt to depict the shared connections or integrations that were occurring. As media are orienting devices, this has profound implications for how migrants are regarded on both the individual as well as the collective levels.

description: Diagnosis and treatment of multiple pulmonary nodules are clinically important but challenging. Prior studies on nodule characterization use solitary-nodule approaches on multiple nodular patients, which ignores the relations between nodules. In this study, we propose a multiple instance learning (MIL) approach and empirically prove the benefit to learn the relations between multiple nodules. By treating the multiple nodules from a same patient as a whole, critical relational information between solitary-nodule voxels is extracted. To our knowledge, it is the first study to learn the relations between multiple pulmonary nodules. Inspired by recent advances in natural language processing (NLP) domain, we introduce a self-attention transformer equipped with 3D CNN, named {NoduleSAT}, to replace typical pooling-based aggregation in multiple instance learning. Extensive experiments on lung nodule false positive reduction on LUNA16 database, and malignancy classification on LIDC-IDRI database, validate the effectiveness of the proposed method.

We compute the decoherence times for the system-field modes and compare them with the other time scales of the model.

description: Most research on how the news media cover race focuses either on perspectives of journalists or on their subjects. Few comparative studies concurrently integrate the perspectives of both these groups and virtually none has done this from a visual standpoint. Using the 2015 race-related Mizzou protests as a case study, this research employs in-depth interviews with photojournalists and their subjects to explore (1) how past experience with people of color impacts photojournalism, (2) how scripted journalistic behavior affects race-related visual coverage, and (3) how photojournalists can better cover race-related issues more accurately. The study's results advance social identity theory and inform the debate about documentary photography's role in civil rights movements and activist causes.

description: Az élelmiszeripari szereplők bizalmi szintje magasabb a korábbi évtizedben mért szintnél, a megkérdezettek körében határozottan érzékelhető a szorosabb összefogás szükségességének felismerése. Az együttműködési lehetőség adott. Kér-dés, hogy a bizalmi szint mennyire mozdítja elő a közös fellépésekhez szükséges összefogást, az egyéni érdekek háttérbe szorítását. Egyértelmű az összefüggés a közös programokban való részvételi hajlandóság és mások KAM programokban való részvételének megítélése között. A közös akciókban részt vevő élelmiszeripari szereplők viszonylag nyitottak egymás felé, ami nagy valószínűséggel abból fakad, hogy érzik az akció pozitív hatását, a többi résztvevő együttműködő magatartását, és élményeiket átvetítik az ágazat többi szereplőjére is. A KAM programokkal való elégedettség megítélésénél elsődleges szempont a szakmai színvonal. A szereplők már túljutottak azon a ponton, amikor csak az anyagi erőforrások nagyságából ítélkeznének. Felismerték a szakmai értékek fontosságát, és egyértelműen első helyre sorolják azt az elégedettségi szempontok között. Az élelmiszeripar szereplőinek nagy része érzi az érdekérvényesítés vál-toztatásának szükségességét, hatékonyságának növelésére tett is már javaslatot különböző fórumokon. Ezek a kezdeményezések azonban nagyrészt eddig nem valósultak meg. - The confidence level of food industry actors is higher than the levels measured in previous decades. Among those questioned, recognition of the need for tighter cooperation can definitely be felt. The opportunity for cooperation is present; the question is how far this confidence level can further cooperation and the sublimation of individual interests, both necessary for joint actions. There is an obvious connection between the willingness to participate in joint programmes and the judgement of others’ participation in CAM programmes. Food industry actors participating in joint actions are fairly open with each other, which probably results from the fact that they feel the positive effects of the action and the cooperative behaviour of the other participants, and transfer their experiences to the other actors in the sector. A primary viewpoint when judging satisfaction with the CAM programme is professional standards. Participants have passed the point where they judge solely based on the scale of financial resources. The have recognised the importance of professional values and clearly list this in pole position among satisfaction indicators. The majority of food industry actors feel the necessity of changing the way interests are enforced and have already made recommendations in various fora for increasing its effectiveness. However, most of these initiatives have yet to be realised.
Quasicrystalline electronic states in twisted bilayers and the effects of interlayer and sublattice symmetries

description: We study the electronic structure of quasicrystals composed of incommensurate stacks of atomic layers. We consider two systems: a pair of square lattices with a relative twist angle of $θ=45^\circ$ and a pair of hexagonal lattices with a relative twist angle of $θ=30^\circ$, with various interlayer interaction strengths. This constitutes every two-dimensional bilayer quasicrystal system. We investigate the resonant coupling governing the quasicrystalline order in each quasicrystal symmetry, and calculate the quasi-band dispersion. The resonant interaction emerges in bilayer quasicrystals if all the dominant interlayer interactions occur between the atomic orbitals that have the same magnetic quantum number. Thus, not only the quasicrystal composed of the widely studied graphene, but also those composed of transition metal dichalcogenides will exhibit the quasicrystalline states. We find that some quasicrystalline states, which are usually obscured by decoupled monolayer states, are more prominent, i.e., "exposed", in the systems with strong interlayer interaction. We also show that we can switch the states between quasicrystalline configuration and its layer components, by turning on and off the interlayer symmetry.

description: In opposition to the current paradigm of the globalized the food system, many regional initiatives have arisen to reorganize the food system into localized or regionalized supply chains. This study explores the existing food supply chain for field fruit and vegetable production within the island of Crete, Greece, by examining the production and distribution of food stuffs through the wholesale system and to determining the geographic and retail terminal points for these Cretan-produced items. Through case studies, this paper examines the typology of production and maps the distribution of vegetables and melons produced on the island as the first step to determining the current level of food system sustainability, and opportunities and barriers for greater sustainability. The findings show that in the case of fresh vegetable and melon production, Crete’s consumption is heavily based on locally grown product which is produced on small, diversified farms.

description: Az Európai Unió bárányból, illetve gidából tartósan behozatalra szorul. A magyar juhhúsexport több mint 90%-a az olasz, a maradék döntő része pedig görög piacra irányul. A juhágazat árbevételének – 2-13 milliárd Ft – több mint 90%-a a báránykereskedelemből származik. A magyarországi bárányexportban a vizsgált időszakban csökkent a darabszám és kis mértékben nőtt az értékesített mennyiség. Az átlagsúly alig változott. Az árak 2005-re 1998-hoz viszonyítva 89,5%-kal emelkedtek. Az alsóbb súlycsoportokban az árak kiegyensúlyozottak, 30 kg felett nagyobb az áringadozás, így növekszik az értékesítés kockázata. A vizsgált időszakban az egy anyára jutó értékesítési súly kis mértékben csökkent, az export szerény mértékű emelkedése a növekvő anyalétszámnak köszönhető, romló fajlagos mutatók mellett. A legmagasabb árat általában karácsonykor, a legalacsonyabbat májusban érik el. A húsvéti időszak árai ingadoznak leginkább, hiszen ebben az időszakban legnagyobb a kínálati piac. A báránykereskedelem liberalizációja a hazai exportban lényegi változást nem eredményezett. - The EU has a long-term need for the import of lambs and kids. More than 90% of Hungary’s exported sheep meat is for the Italian market, while most of the remainder goes to the Greek market. Over 90% of the sheep sector’s return from sales – 2-13 billion Ft – comes from the lamb trade. The number of pieces of Hungarian lamb exported fell in the period examined, whilst the amount sold increased slightly. The average weight hardly changed. By 2005 prices had increased by 89.5% in comparison to 1998. Prices are steady in the lower weight categories with greater price fluctuations above 30 kg, increasing sales risk. During the period examined, the sales weight per one dam fell slightly, the modest rise in exports being due to increased numbers of dams coupled with deteriorating specific indicators. The highest prices are achieved at Christmas, the lowest in May. Prices fluctuate the most during the Easter period when supply is at its peak. Liberalisation of the lamb trade has not produced any fundamental change in domestic export, although the moderation of price rises may be an indirect effect.
title: The leper and the king: the patronage and perception of lepers and leprosy by King Henry III of England and King Louis IX of France
Creators: name: Phillips, Katie
Publisher: name: University of Reading
Year: 2023

description: This thesis explores the connections between leprosy and kingship in thirteenth-century England and France. The kings of England and France, through the anointment they received at their coronation ceremonies, were granted a particular connection with God, and with Jesus Christ. Lepers, because of the extremity of their suffering, which was believed to be purgatorial, were valued for their spirituality. Their intercessory prayers were sought by kings and queens throughout the Middle Ages. This thesis takes a comparative approach as far as is possible with the nature of the available source material. Beginning with the disease of leprosy, it considers the position of lepers in society, both within the religious enclosure and in secular society. The responses of both religious and lay groups towards leprosy were ambiguous, being at once inclusive and exclusive. Kings Henry III and Louis IX went beyond the contemporary expectations of kingship, which would have been sufficed by the provision of charity. They were both reported to have knelt before lepers, and kissed them as though praising and kissing Christ. In this they imitated the behaviour of some of their ancestors. There are connections also to the historic belief in the royal touch, for the cure of scrofula. The patronage of the kings to lepers and leper-houses sheds light on their piety, as well as on their sense of tradition. Leper-houses which had been the beneficiaries of royal patronage in the twelfth century continued, mostly, to receive alms in the thirteenth century. The nature of patronage is also discussed, as the concern for lepers’ material and spiritual welfare is very clear, particularly in the English sources. Although it is only Louis who has traditionally received recognition for his piety, Henry’s actions demonstrate that he too epitomised thirteenth-century spirituality in his reverence for lepers and their spiritual value.

description: The study of emotion in journalism has largely been ignored and, when studied, is relegated almost exclusively to media texts. As such, this research aims to rectify this imbalance by focusing on the human side of journalism practice and the emotional labor and work experienced by documentary visual journalists. It does so through an in-depth, interview-based approach with 23 journalists in eight countries and identifies the sources of emotional labor and work experienced by those in the profession and how visual journalists manage the effects of the emotional labor and work they experience. The findings suggest that emotional labor and work pervade the production, editing, and post-production phases of journalistic work but not equally for all types of visual journalists. Female journalists, in particular, reported unique emotional investment and display practices, while a subset of male journalists reported unique emotional management ones. In addition, almost across the board, the visual journalists in this sample reported relying on more informal rather than formal strategies to manage the effects of their work-related emotions.

description: We run well-established experimental games with urban consumers in five African cities. The aim of the study is to test how standard findings in experimental economics replicate with a non-standard sample and how prosocial attitudes differ when interacting with peers and institutions. Participants play dictator games and trust games with peers or local NGOs as receivers; a public good game, with and without identity manipulation; and two incentivised tasks to elicit risk and time preferences. Preliminary evidence shows larger donations and higher trust towards local NGOs than peers, while identity manipulation does not affect cooperation in the public good game. While average donations and average cooperation levels seem to be in line with the experimental literature, we observe unusually large inconsistencies in risk and time preferences with high variance across cities.

Individual narratives of change in therapeutic enactment
Creators: name: Black, Timothy G
Publisher: name: University of British Columbia

description: This study investigated the subjectively constructed narratives of individual change for lead persons in a Therapeutic Enactment (Westwood, Keats & Wilensky, in press). Narrative investigation of Therapeutic Enactment to date has not been conducted and, as such, the study is important to the field of counselling psychology and the further development of Therapeutic Enactment. In terms of both theory and practice the study expands our understanding of the complexities of the change process in Therapeutic Enactment. It also provides the unique personal contexts related to change and it provides concrete examples of what actually changes in the lives of lead persons in Therapeutic Enactment. In this study, the co-researchers consisted of 4 female lead persons and 2 male lead persons, who had taken part in their own Therapeutic Enactment at a residential retreat on the outskirts of Vancouver, British Columbia, Canada. The co-researchers were interviewed in-depth using person-centred narrative interviewing techniques, combined with semi-structured interview questions. Five narratives were written in the first person focusing on the subjective experience of individual change in Therapeutic Enactment. Each narrative was returned to the respective co-researcher for editing and validation at which point co-researchers removed portions of the narratives they did not want included in the study and then added or amended content that they did want to be included in the study. The principal researcher made the requested changes and then returned final copies of the narratives to each of the co-researchers. The final narratives are presented herein. The co-constructed narratives indicate that lead persons in Therapeutic Enactment experienced change on six general levels including body sensations, emotions, behaviours, thoughts, relationships and spiritual connection. This study provides an in-depth examination of the subjective narratives of individual change in Therapeutic Enactment.

description: We report on the measurements of the spectra of gamma radiation generated by 855 MeV electrons in bent silicon and germanium crystals at MAMI (MAinzer MIkrotron). The crystals were 15 μm thick along the beam direction to ensure high deflection efficiency. Their (111) crystalline planes were bent by means of a piezo-actuated mechanical holder, which allowed to remotely change the crystal curvature. In such a way it was possible to investigate the radiation emitted under planar channeling and volume reflection as a function of the curvature of the crystalline planes. We show that using volume reflection, one can produce intense gamma radiation with comparable intensity but higher angular acceptance than for channeling. We studied the trade-off between radiation intensity and angular acceptance at different values of the crystal curvature. The measurements of radiation spectra have been carried out for the first time in bent Germanium crystals. In particular, the intensity of radiation in the Ge crystal is higher than in the Si one due to the higher atomic number, which is important for the development of the X-ray and gamma radiation sources based on higher-Z deformed crystals, such as crystalline undulator.

description: Pope Francis’s 2015 visit to Cuba provided a unique opportunity for a comparative study of state-controlled and independent media systems. This study, grounded in the interpretivist tradition, uses symbolic convergence theory and fantasy theme analysis to explore how visuals created by United States-based AP Images, United Kingdom-based Reuters, and Cuba-based Prensa Latina reveal the underlying rhetorical visions, ideologies, and priorities of each culture’s media system. More specifically, state-controlled and independent media depicted the Pope’s visit differently in the degree of personalization shown, the social actors who were depicted, the purpose of the visit, how the Pope was shown in relation to others, and the location where the action occurred. Each media system highlighted its news values and priorities through these differences. Additionally, the images revealed two master narratives: Cuba as a model of Catholicism and the Pope as a model of hierarchy and conformity.

description: Regular spatial structures emerge in a wide range of different dynamics characterized by local and/or nonlocal coupling terms. In several research fields this has spurred the study of many models, which can explain pattern formation. The modulations of patterns, occurring on long spatial and temporal scales, can not be captured by linear approximation analysis. Here, we show that, starting from a general model with long range couplings displaying patterns, the spatio-temporal evolution of large scale modulations at the onset of instability is ruled by the well-known Ginzburg-Landau equation, independently of the details of the dynamics. Hence, we demonstrate the validity of such equation in the description of the behavior of a wide class of systems. We introduce a novel mathematical framework that is also able to retrieve the analytical expressions of the coefficients appearing in the Ginzburg-Landau equation as functions of the model parameters. Such framework can include higher order nonlocal interactions and has much larger applicability than the model considered here, possibly including pattern formation in models with very different physical features.

description: This paper explores the use of functional benefits transfer to forecast the effects of waste sites on property values. The results of a meta-analysis of hedonic studies of waste sites are coupled with spatial analysis techniques to produce estimates of the effects of toxic contamination in Areas of Concern (AOCs) in the U.S. Great Lakes. Based on U.S. Census data for median home values, the methods used here suggest that approximately $5.2 billion (2005 dollars) have been lost in residential property values surrounding twenty-three of the AOCs. This compares to estimates that place the cost of remediation of all U.S. AOCs at up to $4.5 billion (2005 dollars). The case study also identifies issues surrounding the use of a meta-analysis with hedonic property value studies to support functional transfer.

description: This paper presents a multinational meta-analysis estimated to identify systematic components of willingness to pay for surface water quality improvements, developed to support benefit transfer for Canadian policy development. Metadata are drawn from stated preference studies that estimate WTP for water quality changes affecting aquatic life habitats—a type of study with few Canadian examples. The goals of this paper are to assess the properties of a multinational (United States/Canada) meta-analysis compared to a single-country (U.S.) analog; illustrate the potential information that may be derived as well as the analytical challenges; and assess the performance of resulting meta-functions for benefit transfer.
