description: William Reid was my grandfather. He married Margaret Massie in 1915 when he was aged 31. He was an apprentice mason at Banchory Devenick, Kincardineshire, Scotland. A son was born in July 1916. It is assumed that William was conscripted in early 1916. I have a panoramic photograph of 274 Company at Plumstead taken in July 1918. William and Margaret had three children: Willie, Margaret and Rosabella (Rosie). I have two family photographs taken post war. The family lived in Alford post-war. William was a cycle engineer and sold records; he had his own business. It is thought he might have been shell-shocked. William died in 1932 of hypertension and haemorrhage.

description: We compiled and investigated the infrared/sub-mm/mm SED of the new outburst star IRAS 05436-0007 in quiescent phase. The star is a flat-spectrum source, with an estimated total luminosity of L_bol ~ 5.6 L_sun, typical of low-mass T Tauri stars. The derived circumstellar mass of 0.5 M_sun is rather high among low-mass YSOs. The observed SED differs from the SEDs of typical T Tauri stars and of 4 well-known EXors, and resembles more the SEDs of FU Orionis objects indicating the presence of a circumstellar envelope. IRAS 05436-0007 seems to be a Class II source with an age of approximately 4x10^5 yr. In this evolutionary stage an accretion disk is already fully developed, though a circumstellar envelope may also be present. Observations of the present outburst will provide additional knowledge on the source.

description: Investigating the Gunn-Peterson trough of high redshift quasars (QSOs) is a powerful way to reveal the cosmic reionization. As one of such attempts, we perform a series of analyses to examine the absorption lines observed with one of the highest redshift QSOs, PSO J006.1240+39.2219, which we previously discovered at z = 6.62. Using the Subaru telescope, we obtained medium-resolution spectrum with a total exposure time of 7.5 hours. We calculate the Ly$α$ transmission in different redshift bins to determine the near zone radius and the optical depth at 5.6$$5.8). All three analyses based on this QSO show increasingly neutral hydrogen towards higher redshifts, adding precious measurements up to z$\sim$6.5.

description: BACKGROUND: Infection with measles virus (MeV) causes immunosuppression and increased susceptibility to other infectious diseases. Only few studies reported a duration of immunosuppression, with varying results. We investigated the effect of immunosuppression on the incidence of hospital admissions for infectious diseases in Vietnamese children. METHODS: We used retrospective data (2005 to 2015; N = 4419) from the two pediatric hospitals in Ho Chi Minh City, Vietnam. We compared the age-specific incidence of hospital admission for infectious diseases before and after hospitalization for measles. We fitted a Poisson regression model that included gender, current age, and time since measles to obtain a multiplicative effect measure. Estimates were transformed to the additive scale. RESULTS: We observed two phases in the incidence of hospital admission after measles. The first phase started with a fourfold increased rate of admissions during the first month after measles, dropping to a level quite comparable to children of the same age before measles. In the second phase, lasting until at least 6 years after measles, the admission rate decreased further, with values up to 20 times lower than in children of the same age before measles. However, on the additive scale the effect size in the second phase was much smaller than in the first phase. CONCLUSION: The first phase highlights the public health benefits of measles vaccination by preventing measles and immune amnesia. The beneficial second phase is interesting, but its strength strongly depends on the scale. It suggests a complicated interaction between MeV infection and the host immunity.
title: Evolution and gene regulation of the genomic imprinting mechanism
Creators: name: Mungall, Andrew James
Publisher: name: The Open University
Year: 2008

description: Genomic imprinting describes an epigenetic mechanism by which genes are active or silent depending on their parental origin. Imprinting exists in plants and mammals, but how this monoallelic expression mechanism has evolved is not understood at the molecular level. Here I describe the mapping, sequencing and analysis of vertebrate orthologous imprinted regions spanning 11.5 Mb of genomic sequence from species with and without genomic imprinting. In eutherian (placental) mammals, imprinting can be regulated by differential DNA methylation, non-coding RNAs, enhancers and insulator elements. The systematic sequence comparison of the IGF2-H19 imprinting cluster, in eutherians and marsupials (tammar wallaby and opossum), has revealed the presence of the enigmatic non-coding RNA H19 in marsupials. Furthermore, we have characterised the marsupial H19 expression status and identified key regulatory elements required for the germline imprinting of the neighbouring IGF2 gene. All the major hallmarks of the imprinting mechanism of the IGF2-H19 locus were found to be conserved in therian mammals. In mammals, this imprinting system is therefore the most conserved germline derived epigenetic mechanism discovered so far.

The high-quality genomic sequences have provided early glimpses of the genomic landscapes for species such as the monotreme platypus and marsupial tammar wallaby for which little was previously known. Comparative sequence analysis was used to identify candidate regulatory elements in the neighbouring imprinting centre 1 and 2 regions of human chromosome 11p15.5. Nine novel enhancer elements were identified following in vitro gene-reporter assays and correlation of conserved sequences with recent ENCODE data revealed probable functions for a further 24 elements.

This project has led to the formation of the Sequence Analysis of Vertebrate Orthologous Imprinted Regions (SAVOIR) consortium and resources developed here are being used by the imprinting community to further our knowledge of the evolution of the genomic imprinting mechanism.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We develop a microscopic theory of the single impurity Kondo effect on a metallic surface. We calculate the hybridization energies for the Anderson Hamiltonian of a magnetic impurity interacting with surface and bulk states and show that, contrary to the Kondo effect of an impurity in the bulk, the hybridization matrix elements are strongly dependent on the momentum around the Fermi surface. Furthermore, by calculating the tunneling conductance of a scanning tunneling microscope (STM), we show that when the magnetic impurity is located at a surface the Kondo effect can occur with equal strength between bulk and surface states. We compare our results with recent experiments of Co impurities in Cu(111) and Cu(100) surfaces and find good quantitative agreement.

description: I am a numismatist. I have no connection to William Gray other than finding a dog tag in a small box of coins that I bought; the dog tag bears his name. The dog tag is a 'Replacement Dog Tag' which was made from a French 10 centime coin. These coins were made over the years 1898 to 1921 and are bronze. The coin now has no date as the reverse face has been ground off then punched to read the following: 'Cpl. Gray C/157 R.F.A. 4364'. The obverse face still shows the Liberty Head facing right which allows identification of the coin. Dog tag is an informal expression used for identity tags. As I understand it the dog tags that were officially issued were not very robust and were easily lost so soldiers often carried unofficial ones as well.

I am grateful to Alan Sim, of the Gordon Highlanders Museum, Aberdeen, who carried out some research. The dog tag has been identified as belonging to Corporal William Gray of the 157th Brigade Royal Field Artillery, Aberdeen. Alan has also supplied some details of this unit. My hope is that I will be able to trace any descendants that William Gray may have so that I can pass the dog tag on.

description: BACKGROUND: Seroepidemiological studies provide important insight into the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV‑2) in our society. We aimed to determine seropositivity of SARS-CoV‑2 antibodies and its cross-sectional correlates in a large cohort of blood donors. METHODS: In this observational cohort study, we tested healthy blood donors residing in Tyrol, Austria, for SARS-CoV‑2 antibodies using the Abbott SARS-CoV‑2 IgG chemiluminescent microparticle immunoassay. We estimated 95% confidence intervals (95% CI) of seroprevalences using bootstrapping and tested for differences by participant characteristics using logistic regression. FINDINGS: Between 8 June and 4 September 2020, we screened 5345 healthy individuals at local blood donor sessions (mean age 42.7 years, SD 13.5 years, 46.7% female). Overall seroprevalence was 3.1% (95% CI 2.7-3.6%, 165 cases), which is 5.1-fold higher (95% CI 4.5-6.0%) than the case number identified by the health authorities in the state-wide testing program (0.6%; 4536 out of 757,634). Seroprevalence was higher in the district Landeck (16.6%, P

description: Flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) are essential cofactors for enzymes, which catalyze a broad spectrum of vital reactions. This paper intends to compile all potential FAD/FMN-binding proteins encoded by the genome of Arabidopsis thaliana. Several computational approaches were applied to group the entire flavoproteome according to (i) different catalytic reactions in enzyme classes, (ii) the localization in subcellular compartments, (iii) different protein families and subclasses, and (iv) their classification to structural properties. Subsequently, the physiological significance of several of the larger flavoprotein families was highlighted. It is conclusive that plants, such as Arabidopsis thaliana, use many flavoenzymes for plant-specific and pivotal metabolic activities during development and for signal transduction pathways in response to biotic and abiotic stress. Thereby, often two up to several homologous genes are found encoding proteins with high protein similarity. It is proposed that these gene families for flavoproteins reflect presumably their need for differential transcriptional control or the expression of similar proteins with modified flavin-binding properties or catalytic activities.
title: The influence of ice disturbance on nearshore benthic communities at Adelaide Island, Antarctica
Creators: name: Smale, Daniel Alexander
Publisher: name: The Open University
Year: 2007

description: Ice disturbance is frequently cited as having a major role in structuring benthic communities in shallow polar waters, and yet comprehensive field studies on the direct effects of ice disturbance are rare. This thesis aimed to describe the role of ice disturbance in determining benthic community structure at sites around Rothera Point, Adelaide Island (67° 34.5' S, 68° 07.0' W). The work comprised of two main components; a range of observational studies to describe the general effects of ice disturbance, and an experimental quantification of the disturbance pressure, which was then used to make novel links between disturbance and community structure. A photographic survey using depth transects (0-35 in depth) at three sites showed that benthic assemblages changed continuously along a bathymetric gradient. Assemblages were most patchy at shallow depths and the relative abundance of sessile forms increased with depth, which suggested that disturbance intensity was greatest in the shallows. The immediate effects of iceberg impacts were also investigated. Communities within newly formed iceberg scours were sampled and compared with those in undisturbed areas; scoured assemblages were 95% lower in mean macrofaunal abundance and 75.9% lower in species richness. The recovery of three scour assemblages was monitored for ~30 months following the disturbance event. Scoured assemblages became increasingly similar to undisturbed assemblages over time and marked spatial variability was observed in both scoured and unscoured zones. Experimental markers were designed to detect iceberg impacts and were deployed as 24 grids at four depth increments and two study sites. Markers were surveyed regularly for two years to quantify the frequency of iceberg impacts, which varied significantly with depth, site, season and year. The intensity of disturbance was greatest in the shallows (0-5 m depth) and significantly reduced at 25 m depth. Variation between site and season could be largely explained by the duration of winter fast ice. Extensive sampling at each of the disturbance grids showed that disturbance intensity has a significant and wide-ranging influence on macrobenthic community structure.

description: The ethical concept of fairness has recently been applied in machine learning (ML) settings to describe a wide range of constraints and objectives. When considering the relevance of ethical concepts to subset selection problems, the concepts of diversity and inclusion are additionally applicable in order to create outputs that account for social power and access differentials. We introduce metrics based on these concepts, which can be applied together, separately, and in tandem with additional fairness constraints. Results from human subject experiments lend support to the proposed criteria. Social choice methods can additionally be leveraged to aggregate and choose preferable sets, and we detail how these may be applied.

description: The complexation of oppositely charged colloidal objects is considered in this paper as a thermodynamic micellization process where each kind of object needs the others to micellize. This requirement gives rise to quantitatively different behaviors than the so-called mixed-micellization where each specie can micellize separately. A simple model of the grand potential for micelles is proposed to corroborate the predictions of this general approach.

description: Biodeterioration of monuments is one of the principal fields of interest for researchers in the conservation of cultural heritage. Microorganisms which are living on inorganic substrate can settle and spread on and into the rock materials and cause biological damages.The aim of this study was to assay effectiveness of chemical treatment which is applied in the restoration and renovation of cultural heritage by using a fluorometric method. Because cell viability is a critical parameter for assessment of success of biocide treatments, one of the objectives of research was to find a reliable method to estimate the efficacy of chemicals on rock fungi. The fluorometry tests were performed with two isolates A18 (Trimmatostroma abietis) and J26 (Exophilia jeanselmei). The cells were treated by Alkyl benzyl dimethyl ammonium chloride (BAC) 1%. Then the cells were stained with FDA (fluorescein diacetate) and Cal AM (Calcein AM), PI (Propidium Iodide), and combinations of them. The fluorometric method was done to measure the alterations of cell viability after chemical treatment. FDA stained cells performed a strong staining under microscopic as well as fluorometric recording. After cells were incubated in presence of Cal AM, fluorescence of individual cells was measured and a weak fluorescence was observed. Fungi stained by PI were not visible in any microscopic experiment. Furthermore, the fluorometric method did not show any considerable fluorescence intensity of PI stained cells. When combination of dyes was used, stained cells had not only a low yield qualitatively and quantitatively, also the fluorescence intensity of FDA was decreased. On the contrary, when FDA was used alone, strong fluorescence intensity was shown and it could well be used for chemical treatment assays and to quantify the efficacy of the chemical treatment. FDA fluorometry is accurate, reproducible and economic in both time and materials spent
Cosmological Growth History of Supermassive Black Holes and Demographics in the High-z Universe : Do Lyman-Break Galaxies Have Supermassive Black Holes?

description: We study the demographics of supermassive black holes (SMBHs) in the local and high-z universe with hard X-ray luminosity functions (HXLFs) of AGNs. First, we compare the mass accretion history at z>0 with optical luminosity functions (OLFs) and that with HXLFs. We consider the constraints on parameters of mass accretion (energy conversion efficiency and Eddington ratio) and conclude that the constraints based on HXLFs are more adequate rather than that based on OLFs. The sub-Eddington case is allowed only when we use HXLFs. Next, we estimate the upper limit of the cumulative mass density of SMBHs at any redshifts. For an application, we examine if Lyman-Break galaxies (LBGs) at z=3 already have SMBHs in their centers which is suggested by recent observations. If most of LBGs already has massive SMBHs at z=3, the resultant mass density of SMBHs at z=0 should exceed the observational estimate because such SMBHs should further grow by accretion. We show that the special conditions should be met in order that a large part of LBGs have SMBHs (for example, large energy conversion efficiency and frequent mergers and/or direct formations at z>3). The possibility that nearly all LBGs have SMBHs with large mass ratio, such as M_BH/M_stellar > 0.005, is reliably ruled out.(abridged)

We construct minimal generalized solutions under certain generalized energy conditions on $σ$ and $μ$. To prove this, we give new estimates for interaction between measures. We also construct solutions to equations with several sub-natural growth terms using the same methods.

description: We reinvestigate the large degeneracy solution of the multichannel Kondo problem, and show how in the universal regime the complicated integral equations simplifying the problem can be mapped onto a first order differential equation. This leads to an explicit expression for the full zero-temperature scaling functions at - and away from - the intermediate non Fermi Liquid fixed point, providing complete analytic information on the universal low - and intermediate - energy properties of the model. These results also apply to the widely-used Non Crossing Approximation of the Anderson model, taken in the Kondo regime. An extension of this formalism for studying finite temperature effects is also proposed and offers a simple approach to solve models of strongly correlated electrons with relevance to the physics of heavy fermion compounds.

description: In hierarchical models, density fluctuations on different scales are correlated. This induces correlations between dark halo masses, their formation histories, and their larger-scale environments. In turn, this produces a correlation between galaxy properties and environment. This correlation is entirely statistical in nature. We show how the observed clustering of galaxies can be used to quantify the importance of this statistical correlation relative to other physical effects which may also give rise to correlations between the properties of galaxies and their surroundings. We also develop a halo model description of this environmental dependence of clustering.

description: The pedestrian-induced instability of the London Millennium Bridge is a widely used example of Kuramoto synchronisation. Yet, reviewing observational, experimental, and modelling evidence, we argue that increased coherence of pedestrians' foot placement is a consequence of, not a cause of the instability. Instead, uncorrelated pedestrians produce positive feedback, through negative damping on average, that can initiate significant lateral bridge vibration over a wide range of natural frequencies. We present a simple general formula that quantifies this effect, and illustrate it through simulation of three mathematical models, including one with strong propensity for synchronisation. Despite subtle effects of gait strategies in determining precise instability thresholds, our results show that average negative damping is always the trigger. More broadly, we describe an alternative to Kuramoto theory for emergence of coherent oscillations in nature; collective contributions from incoherent agents need not cancel, but can provide positive feedback on average, leading to global limit-cycle motion.

description: The important role of the electron-phonon interaction (EPI) in explaining the properties of the normal state and pairing mechanism in high-T$_{c}$ superconductors (HTSC) is discussed. A number of experimental results are analyzed such as: dynamical conductivity, Raman scattering, neutron scattering, ARPES, tunnelling measurements, isotope effect and etc. They give convincing evidence that the EPI is strong and dominantly contributes to pairing in HTSC oxides. It is argued that strong electronic correlations in conjunction with the pronounced (in relatively weakly screened materials) EPI are unavoidable ingredients for the microscopic theory of pairing in HTSC oxides. I present the well defined and controllable theory of strong correlations and the EPI. It is shown that strong correlations give rise to the pronounced \textit{forward scattering peak} in the EPI - the FSP theory. The FSP theory explains in a consistent way several (crucial) puzzles such as much smaller transport coupling constant than the pairing one ($λ_{tr}\ll λ$), which are present if one interprets the results in HTSC oxides by the old Migdal-Eliashberg theory for the EPI. The ARPES shift puzzle where the nodal kink at 70 meV is unshifted in the superconducting state, while the anti-nodal one at 40 meV is shifted can be explained at present only by the FSP theory. A number of other interesting predictions of the FSP theory are also discussed.

title: Social media platforms as economic organisations: reconstructing the evolution of TripAdvisor’s operations

description: Social media platforms have gradually become embedded in the digital economy. During this process, their original identity as sites that exclusively facilitated content sharing and user networking has changed significantly. The so-called “social media” literature has traditionally centred on user’s capabilities to networking, sharing content and building community. The “digital platforms” literature has focused on the rules, conditions and governance of resource exchanges between multiples sides of a platform. The “ecosystem literature” has focused on understanding the emergence of a complex web of commercial relationships that prompt value creation. Meaningful as they are, current literature tends to treat technology as a black box by overlooking the ways it moulds perceptions, attitudes, relations, and actions. This study fills this gap by critically examining the role of data and technology in social media platforms. It argues that social media form part of the digital economy by developing both technological and organisational capability to exploit data systematically. The thesis advances these ideas through the study of TripAdvisor from its creation in 2000 through 2019. It uses qualitative analysis complemented with digital methods. The analysis reveals several stages in TripAdvisor’s evolution. Each stage is closely related to TripAdvisor’s capabilities and strategies for procuring, producing and exchanging data with its ecosystem. The thesis develops a general framework that contributes to uncovering the technological, organisational, and economic complexities involved in the evolution of social media. It explains the structural transformations of social media platforms and their current embeddedness in webs of relationships, characteristic of the digital economy. The thesis suggests that the platform’s identity is the result of an intricate interplay of strategies, technology, actors, relationships and practices that influence and reinforce one another.

description: Adolescents living with HIV have poor virological suppression and high levels of common mental disorders. In Zimbabwe the Zvandiri adolescent peer support programme is effective at improving ART adherence and virological suppression. We assessed the effect of training peer supporters in problem-solving therapy (PST) using a cluster-randomised controlled trial. Sixty clinics stratified by district were randomised 1:1 to either normal Zvandiri peer support or a peer supporter trained in PST by Friendship Bench. We enrolled 842 adolescents aged 11-19. The primary outcome was virological non-suppression, defined as viral load ≥1000 copies. Secondary outcomes were symptoms of common mental disorder measured with the Shona Symptom Questionnaire (SSQ, cutpoint 8/14) and depression measured with the Patient Health Questionnaire (PHQ-9, cutpoint 10/27), and health utility score using the EQ-5D (range 0-1, cutpoint 1). Analysis was at the individual level with a random effect for clustering. Case reviews and focus group discussions were used for qualitative analysis to determine feasibility.

description: The Partition of Republic of India was the method of dividing the sub-continent onsectarian lines, which occurred in 1947 as Republic of India gained its independence fromBritish Empire. The northern half preponderantly Muslim, became nation of Islamic Republicof Pakistan and therefore the southern preponderantly Hindu became the Republic ofRepublic of India, the partition but desolate each Republic of India and Islamic Republic ofPakistan because the method claimed several lives in riots, rapes, murders and pillage. Thetwo countries began their independence with ruined economies and lands while not alongtime, skilled system of state, not solely this, however conjointly concerning fifteen millionindividuals were displaced from their homes. The Partition of Republic of India was a vitalevent not solely within the history of the Indian landmass however in world history. Its chiefreason was the communal thinking of each Hindus and Muslins; however the circumstancesbeneath that it occurred created it one among the saddest events of the history of Republic ofIndia. No doubt, the Hindus and therefore the Muslims were inhabitation since long howeverthey did not instill the emotions of harmony and unity among themselves. The fanatic leadersof each community compete a distinguished role in stoking the hearth of communalism. Thepartition was exceptionally brutal and huge in scale and unleashed misery and loss of livesand property as countless refugees fled either Islamic Republic of Pakistan or Republic ofIndia.

description: We study theoretically the transmission properties of serially connected mesoscopic rings threaded by a magnetic flux. Within a tight-binding formalism we derive exact analytical results for the transmission through periodic and quasiperiodic Fibonacci arrays of rings of two different sizes. The role played by the number of scatterers in each arm of the ring is analyzed in some detail. The behavior of the transmission coefficient at a particular value of the energy of the incident electron is studied as a function of the magnetic flux (and vice versa) for both the periodic and quasiperiodic arrays of rings having different number of atoms in the arms. We find interesting resonance properties at specific values of the flux, as well as a power-law decay in the transmission coefficient as the number of rings increases, when the magnetic field is switched off. For the quasiperiodic Fibonacci sequence we discuss various features of the transmission characteristics as functions of energy and flux, including one special case where, at a special value of the energy and in the absence of any magnetic field, the transmittivity changes periodically as a function of the system size.

description: INTRODUCTION: The guidelines for differentiated service delivery (DSD) for HIV treatment became operational in Cameroon in 2017 with the Test and Treat national strategy elaborating services that can be decentralized and task shifted at community level, but with little to no guidelines for DSD in fragile and conflict-affected settings. Since 2016, more than 680,000 Cameroonians have been internally displaced due to the conflict in the North West and South West regions (NWSW). This conflict has impacted on the health system with numerous attacks on health facilities and staff, reducing access to health care for internally displaced persons. The outbreak of COVID-19 further reduced humanitarian responses for fear of spreading COVID-19. Mobile clinics were utilized as a model of care in piloting DSD for HIV in conflict-affected settings within the COVID-19 context. METHODS: The HIV DSD framework was used to evaluate a project that used mobile clinics in 05 divisions across the NWSW to provide primary health care to internally displaced persons in hard-to-reach areas. These mobile clinics were operated in the COVID-19 context and integrated HIV services in the benefit package. The mobile clinics mainstreamed HIV and COVID-19 sensitization during community mobilization, HIV consultations, HIV testing and referrals, and in some cases antiretroviral (ARV) dispensation. The project ran from March to October 2020. The results from the evaluation of this model of HIV care delivery were analysed in 06 of 08 mobile clinics. RESULTS: In 07 months, a total of 14,623 persons living in conflict-affected settings were sensitized on HIV, 1979 received HIV testing from which 122 were positive and 33 placed on ARVs. 28 loss-to-follow up people living with HIV were relinked to treatment and 209 consultations for persons living with HIV were conducted. Despite the good collaboration at regional and field level, there was distrust by ARV centers for humanitarian organizations. CONCLUSION: Mobile clinics are a model of care which could be leveraged in fragile and conflict-affected settings as an alternative model of care for HIV DSD to ensure continuum of HIV care and treatment. However this should be integrated within the benefit package of primary health care services offered by mobile clinics.

description: Because of record export growth, U.S. food processors posted a trade surplus in 1992 for the first time. The appeal of American brand names and the influence of U.S. multinational firms abroad should strengthen that position in the face of stiff world competition. U.S. firms sell in a world market where trade in processed foods exceeded $205 billion in 1990. Two dozen countries supplied 80 percent of that amount. Over half of all shipments originated in Western Europe and North America. The United States accounted for 8.5 percent of world exports of processed foods in 1990, surpassed only by France with 9.8 percent and The Netherlands with 8.9 percent.
