description: We apply the recently developed asymmetric ARDL cointegration methodology of Shin et al. (2011) to analyse the relationship between agricultural financing and economic growth of Tanzania. In this approach, short run and long run asymmetries are introduced via positive and negative partial sum decompositions of exogenous variables, and the model is estimable by standard OLS. Our findings reveal supporting evidence of asymmetric interactions among the examined variables in the short run and long run. The findings further reveal that endogenous variables react differently to positive and negative shocks of exogenous variables. Positive shocks of agricultural financing have considerably larger positive impacts on economic growth compared to negative shocks, while any unfavourable economic conditions would clobber agricultural financing. In light of our findings, we conclude that the existing asymmetric relationship between agricultural financing and economic growth should be taken into account and the government should increase its financing of the agriculture sector.

description: The magnetic and superconducting properties of a series of underdoped $Ba_{1-x}Na_{x}Fe_{2}As_{2}$ (BNFA) single crystals with $0.19 \leq x\leq 0.34$ has been investigated with the complementary muon-spin-rotation ($μ$SR) and infrared spectroscopy techniques. The focus has been on the different antiferromagnetic states in the underdoped regime and their competition with superconductivity, especially for the ones with a tetragonal crystal structure and a so-called double-$Q$ magnetic order. Besides the collinear state with a spatially inhomogeneous spin-charge-density wave (i-SCDW) order at $x=0.24$ and $0.26$, that was previously identified in BNFA, we obtained evidence for an orthomagnetic state with a "hedgehog"-type spin vortex crystal (SVC) structure at $x=0.32$ and $0.34$. Whereas in the former i-SCDW state the infrared spectra show no sign of a superconducting response down to the lowest measured temperature of about 10K, in the SVC state there is a strong superconducting response similar to the one at optimum doping. The magnetic order is strongly suppressed here in the superconducting state and at $x=0.34$ there is even a partial re-entrance into a paramagnetic state at $T<

description: We describe an experiment showing a spontaneous symmetry breaking phenomenon between the intensities of the ordinary and extraordinary components of the fundamental field in intracavity type-II harmonic generation. It is based on a triply resonant dual cavity containing a type II phase matched $χ^{(2)}$ crystal pumped at the fundamental frequency $ω_0$. The pump beam generates in the cavity a second harmonic mode at frequency $2ω_0$ which acts as a pump for frequency degenerate type II parametric down conversion. Under operating conditions which are precisely symmetric with respect to the ordinary and extraordinary components of the fundamental wave, we have observed a breaking of the symmetry on the intensities of these two waves in agreement with the theoretical predictions.

description: Ancient origins of a modern anthropic argument against cosmologies involving infinite series of past events are considered. It is shown that this argument - which in modern times has been put forward by distinguished cosmologists like Paul C. W. Davies and Frank J. Tipler - originates in pre-Socratic times and is implicitly present in the cyclical cosmology of Empedocles. There are traces of the same line of reasoning throughout the ancient history of ideas, and the case of a provocative statement of Thucydides is briefly analyzed. Moreover, the anthropic argument has been fully formulated in the epic of Lucretius, confirming it as the summit of ancient cosmology. This is not only of historical significance but presents an important topic for the philosophy of cosmology provided some of the contemporary inflationary models, particularly Linde's chaotic inflation, turn out to be correct.

description: We discuss the general and approximate angular diameter distance in the Friedman-Robertson-Walker cosmological models with nonzero cosmological constant. We modify the equation for the angular diameter distance by taking into account the fact that locally the distribution of matter is non homogeneous. We present exact solutions of this equation in a few special cases. We propose an approximate analytic solution of this equation which is simple enough and sufficiently accurate to be useful in practical applications.

description: Roughening of interfaces implies the divergence of the interface width $w$ with the system size $L$. For two-dimensional systems the divergence of $w^2$ is linear in $L$. In the framework of a detailed capillary wave approximation and of statistical field theory we derive an expression for the asymptotic behaviour of $w^2$, which differs from results in the literature. It is confirmed by Monte Carlo simulations.

title: The human B cell response to a pneumococcal conjugate vaccine.
Creators: name: Clutterbuck, Elizabeth Ann
Publisher: name: The Open University
Year: 2008

description: The heptavalent pneumococcal polysaccharide-CRM197 conjugate vaccine (Pnc7) has been introduced to target the major disease causing pneumococcal serotypes (4, 6B, 9V, 14, 18C, 19F and 23F) in childhood where invasive pneumococcal disease remains a significant global cause of childhood mortality. The aim of this thesis was to address questions related to the pneumococcal capsular polysaccharide specific B cell response. One week after a single dose of Pnc7 vaccine it was possible to detect spontaneously secreting IgG plasma cells in the peripheral blood of 12 month old toddlers and young adults. The plasma cells were identified as either CD20+CD27+sIg+CD38+ or CD20-CD27+sIglo/-CD38+. Prior to immunisation memory B cells specific for pneumococcal capsular polysaccharides were present in 100% of young adults, but barely detectable in adults aged 47-65 years and were undetectable in toddlers. A single dose of Pnc7 induced elevated frequencies of IgG memory B cells in all age groups, but two doses were required in order to generate equivalent frequencies in adults and toddlers. The generation of IgG memory was dependent on age at time of immunisation and on the serotype polysaccharide. Generation of IgG memory requires previous natural exposure or immunisation to prime the immune system. Such exposure generates IgM memory in young children and enhancing IgM memory may be important for protection. The IgM response can be replaced by generation of a high avidity IgG response, enhance protection of the very young and elderly through immunisation.

description: Velocity statistics is a direct probe of the dynamics of interstellar turbulence. Its observational measurements are very challenging due to the convolution between density and velocity and projection effects. We introduce the projected velocity structure function, which can be generally applied to statistical studies of both sub- and super-sonic turbulence in different interstellar phases. It recovers the turbulent velocity spectrum from the projected velocity field in different regimes, and when the thickness of a cloud is less than the driving scale of turbulence, it can also be used to determine the cloud thickness and the turbulence driving scale. By applying it to the existing core velocity dispersion measurements of the Taurus cloud, we find a transition from the Kolmogorov to the Burgers scaling of turbulent velocities with decreasing length scales, corresponding to the large-scale solenoidal motions and small-scale compressive motions, respectively. The latter occupy a small fraction of the volume and can be selectively sampled by clusters of cores with the typical cluster size indicated by the transition scale.

description: This paper establishes whether development assistance for health buy better results in maternal health in Tanzania using annual time series data for the period between 1995 and 2014 based on Autoregressive Distributed Lags (ARDL) and Error Correction Model. A long run cointegration relationship exists between GDP per capita, maternal mortality, unemployment and development assistance for health over examined period of time. The results show that in the long run Development Assistance for Health (DAH) and Economic growth (measured by real GDP per capita) was significant in reducing maternal mortality in Tanzania. In the short run, unemployment was statistically significant on increasing maternal mortality in Tanzania between 1995 and 2014. Furthermore, the short run results show that both DAH and real GDP per capita reduces maternal mortality between 1995 and 2014. The results imply that Development Assistance for Health (DAH) channeled to the health sector is an important component in improvements of maternal health in Tanzania. The findings are robust to sensitivity analyses and estimation methods.

description: We have studied radiative pion decays Pi+ -> e+ nu gamma in three broad kinematic regions using the PIBETA detector and a stopped pion beam. Based on Dalitz distributions of 42,209 events we have evaluated absolute Pi -> e nu gamma branching ratios in the three regions. Minimum chi^2 fits to the integral and differential (E(e+),E(gamma)) distributions result in the axial-to-vector weak form factor ratio of gamma = F_A/F_V = 0.443(15),or F_A = 0.0115(4) with F_V = 0.0259. However, deviations from Standard Model predictions in the high-E(gamma)/low-E(e+) kinematic region indicate the need for further theoretical and experimental work.

Some otherwhere : Édouard Glissant and the Caribbean landscape in contemporary art

description: Over the past two decades, Édouard Glissant’s writings have gained ever-increasing prominence in the fields of post-colonial theory, Caribbean studies, and Francophone literature. They have also been widely used in art and exhibition practice as a ‘tool-kit’ for the display of works relating to themes of globalisation, migration, and diaspora. Glissant was interested and engaged in the arts during his lifetime, but it is not, however, this work that has gained in popularity. Instead, short quotations from his theoretical texts, or isolated terms, including ‘opacity’, ‘relation’, and ‘creolisation’, are utilised in extraction. This thesis returns to the conceptual possibilities of Glissant’s geo-poetic terms for the analysis of art that conveys the Caribbean landscape. Although it is undeniable that Glissant’s writings have a global resonance, his central and repeating tropes are fundamentally embedded in the imagery and experience of the Caribbean archipelago. Against the aims of a colonial project that rationalises and stabilises through the instrumentalisation and control of nature, Glissant’s concept of the Otherwhere – a space that is simultaneously lived and imagined – is proposed throughout this research as a lens through which to incorporate post-colonial discourse within the analysis of identity, ecology, and visual art. In so doing, my work exposes the limits of schemas of visibility and representation that preclude multiplicity and performativity, and offers imaginative ways of figuring relations between individuals and their encounters with landscapes. Under the chapters ‘The Sea’, ‘The Archipelago’, ‘The Spiral of Return and the Common-Place’, ‘Retaining Opacity while Communicating with the Tout-monde’, and ‘The Unrealised Museum’, works by well-known practitioners including John Akomfrah, Janine Antoni, and Coco Fusco are read alongside those of lesser-known artists who work within, from, and between islands of the Caribbean, including: Nadia Huggins, Stacey Tyrell, Ewan Atkinson, and Annalee Davis. In media ranging between photography, moving-image, and performance, these artists share a concern with environmentalism, climate change, community, and the experience of personal identity in relation to the specificities of place. Relational post-colonial ecologies framed through landscape imagery therefore call for analysis and modes of display that are carefully positioned between the aesthetic and the political – a process that is destabilising to perception, and which raises timely questions about precarity, progress, (in)visibility, and belonging.

description: Context. Spectroscopy of exoplanets is very challenging because of the high star-planet contrast. A technical difficulty in the design of imaging instruments is the noncommon path aberrations (NCPAs) between the adaptive optics (AO) sensing and the science camera, which induce planet-resembling stellar speckles in the coronagraphic science images. In an observing sequence of several long exposures, quickly evolving NCPAs average out and leave behind an AO halo that adds photon noise to the planet detection. Static NCPA can be calibrated a posteriori using differential imaging techniques. However, NCPAs that evolve during the observing sequence do not average out and cannot be calibrated a posteriori. These quasi-static NCPAs are one of the main limitations of the current direct imaging instruments such as SPHERE, GPI, and SCExAO. Aims. Our aim is to actively minimize the quasi-static speckles induced in long-exposure images. To do so, we need to measure the quasi-static speckle field above the AO halo. Methods. The self-coherent camera (SCC) is a proven technique which measures the speckle complex field in the coronagraphic science images. It is routinely used on the THD2 bench to reach contrast levels of <10^{-8} in the range 5-12 λ/D in space-related conditions. To test the SCC in ground conditions on THD2, we optically simulated the residual aberrations measured behind the SPHERE/VLT AO system under good observing conditions. Results. We demonstrate in the laboratory that the SCC can minimize the quasi-static speckle intensity in the science images down to a limitation set by the AO halo residuals. The SCC reaches 1σ raw contrast levels below 10^{-6} in the region 5-12 λ/D at 783.25 nm in our experiments.

description: This study analyzed the impact of oil price shocks on agricultural commodity prices in Nigeria using monthly data on oil prices, maize, wheat and soybean and exchange rate from 1997 to 2016. Data on oil price and exchange rate were obtained from the central bank statistical bulletin while those of agricultural commodities were obtained from Food Agricultural Organization (FAO) website. Dummy variables were used to capture periods of structural breaks in the selected agricultural commodity prices. Linear ARDL and Non-linear ARDL with and without breaks were estimated. Asymmetric test using Wald Statistics revealed evidence of asymmetries in all the cases implying that positive and negative shocks of the same magnitude did not have equal impact on agricultural commodity prices. The study found significant positive oil price changes in all cases with the expected positive sign, implying that increases in oil price lead to increases in agricultural commodities. Similarly, exchange rate (a control variable) showed positive significant relationship with agricultural commodities. It is concluded that oil price has overall positive relationship and significant effect on agricultural commodity prices. The study recommended that since oil price was important in agricultural commodities prices, efforts should be geared towards local development of the oil sector as this will bring about positive spillover effect on the agricultural sector and ensure food availability at affordable prices thereby improving standard of living and welfare.

description: We cast a theoretical model based on Effective Semiconductor Maxwell-Bloch Equations and study the dynamics of a multi-mode mid-Infrared Quantum Cascade Laser in Fabry Perot with the aim to investigate the spontaneous generation of optical frequency combs. This model encompasses the key features of a semiconductor active medium such as asymmetric,frequency-dependent gain and refractive index as well as the phase-amplitude coupling of the field dynamics provided by the linewidth enhancement factor. Our numerical simulations are in excellent agreement with recent experimental results, showing broad ranges of comb formationin locked regimes, separated by chaotic dynamics when the field modes unlock. In the former case, we identify self-confined structures travelling along the cavity, while the instantaneous frequency is characterized by a linear chirp behaviour. In such regimes we show that OFC are characterized by concomitant and relevant amplitude and frequency modulation.

description: In this paper we exploit concepts of information theory to address the fundamental problem of identifying and defining the most suitable tools to extract, in a automatic and agnostic way, information from a generic string of characters. We introduce in particular a class of methods which use in a crucial way data compression techniques in order to define a measure of remoteness and distance between pairs of sequences of characters (e.g. texts) based on their relative information content. We also discuss in detail how specific features of data compression techniques could be used to introduce the notion of dictionary of a given sequence and of Artificial Text and we show how these new tools can be used for information extraction purposes. We point out the versatility and generality of our method that applies to any kind of corpora of character strings independently of the type of coding behind them. We consider as a case study linguistic motivated problems and we present results for automatic language recognition, authorship attribution and self consistent-classification.

Material und Methode: Insgesamt 68 parodontal behandelte Patienten mit im-plantatgetragenen Einzelkronen und Brücken wurden in Intervallen von 3 bis 6 Monaten über den Zeitraum von 5 bis 20 Jahren engmaschig nachbeobachtet. Bei allen Recall-Terminen wurden klinische Parameter an Implantaten erhoben. Zweidimensionale Röntgenbilder wurden nach Eingliederung der Suprakonstruk-tion (Baseline) sowie nach 1, 3, 5, 10, 15 und 20 Jahren aufgenommen. Es wurden 39 DVT-Aufnahmen für Oberkiefer-Front und Oberkiefer-Seitenzahnbereich sowie 37 DVT-Aufnahmen im Unterkiefer-Seitenzahnbereich vermessen. Entsprechend den Messungen wurde der Ober – und Unterkiefer in 4 Morphotypen eingeteilt: Morphotyp 1 mit schmalem und hohem Alveolarfort-satz, Morphotyp 2 mit schmalem und tiefem Alveolarfortsatz, Morphotyp 3 mit breitem und hohem Alveolarfortsatz, Morphotyp 4 mit breitem und tiefem Alveo-larfortsatz. Die Überlebensraten der Implantate wurden anhand einer Kaplan-Meier Analyse ermittelt. Vergleiche zwischen den Morphotypen wurden mit dem nichtparametrischen Kruskal-Wallis-Test und multiple Vergleiche mit dem nicht-parametrischen Dunn-Test durchgeführt.
Ergebnisse: Die Überlebensrate aller Implantate betrug nach 5 Jahren 97,7%, nach 10 Jahren 95,2% und nach 20 Jahren 90,3%. Patienten mit Morphotyp 3 im Oberkiefer-Seitenzahnbereich wiesen eine kürzere Überlebensrate der Im-plantate auf als Patienten mit Morphotyp 1, 2 und 4 (p<0,01). Der periimplantä-re Knochenabbau aller Implantate betrug nach 1 Jahr 1,56mm, nach 5 Jahren 1,68mm, nach 10 Jahren 1,74mm und nach 20 Jahren 1,93mm. 
Im Oberkiefer-Seitenzahnbereich und Unterkiefer zeigte sich, dass der periim-plantäre Knochenabbau bei Patienten mit dem Morphotyp 2 signifikant geringer war.
Schlussfolgerung: Implantate bei Patienten mit dem Morphotyp 3 (breiter und hoher Alveolarfortsatz) wiesen im Oberkiefer-Seitenzahnbereich eine kürzere Überlebensdauer auf. Implantate bei Patienten mit Morphotyp 2 (Schmaler und tiefer Alveolarfortsatz) im Oberkiefer-Seitenzahnbereich und Unterkiefer wiesen einen geringeren Knochenabbau auf.

description: We created an augmented reality platform for spatial exploration that recognizes buildings facades and displays various multimedia for different time points. In order to provide the user with the best user experience fast recognition and stable tracking are the key elements of any augmented reality app. In an outdoor environment, lighting, reflective surfaces and occlusion can drastically affect the user experience. In a setup where these conditions are similar, marker creation methodology and the app parameters are key. In this paper we focus on resizing the photo prior marker creating and the importance of camera calibration and resolution and their effect on the recognition speed and quality of tracking outdoor objects.

description: The study investigates the relationship between energy consumption, economic growth and health outcomes in a representative of sub-Saharan Africa (SSA) countries. Annual data over 1990-2014 were sourced from World Bank's World Development Indicators (2016) and fitted in a panel vector autoregression model. The study reveals that neither economic growth nor energy consumption was found to affect health outcomes significantly. The study however shows that medical factor such as health care expenditure remains an important determinant of health outcomes in SSA. However, all the variables employed in the study have joint significance to Granger-cause health outcomes, but individually only CO2 causes a marked change in health outcomes. Neutrality hypothesis in causal relation is found to hold. No evidence of causality running from proxy of health outcome to energy consumption or economic growth. Likewise, no evidence of causal pattern running from either energy consumption or economic growth to health outcome is found..

description: Key reconciliation of quantum key distribution (QKD) is the process of correcting errors caused by channel noise and eavesdropper to identify the keys of two legitimate users. Reconciliation efficiency is the most important figure for judging the quality of a reconciliation scheme. To improve reconciliation efficiency, rate-compatible technologies was proposed for key reconciliation, which is denoted as the single-matrix ratecompatible reconciliation (SRCR). In this paper, a recently suggested technique called multi-matrix reconciliation is introduced into SRCR, which is referred to as the multi-matrix rate-compatible reconciliation (MRCR), to further improve reconciliation efficiency and promote the throughput of SRCR. Simulation results show that MRCR we proposed outperforms SRCR in reconciliation efficiency and throughput.

description: Ziel der Studie war es, einen neuen automatischen Algorithmus zur Erkennung von Flusslimitationen im Schlaf zu verwenden, um hiermit die Atemphysiologie im Schlaf zu beschreiben. Hierzu erfolgte die Aufzeichnung einer vollständigen Polysomnographie von 25 Probanden inklusive des aktuellen Goldstandards zu Detektion von Flusslimitationen, dem Ösophaguskatheter sowie der neuen Methode, dem Obstruktionskoeffizienten. 
Mit Hilfe des Obstruktionskoeffizienten ist es nun erstmals möglich, alle Atemzüge einer nächtlichen Messung im Schlaf bzgl. der Merkmale von Flusslimitierung objektiv zu beschreiben. Entgegen der Annahmen aus den bisherigen Publikationen ergibt sich aber überhaupt kein Zusammenhang zwischen dem Anteil stark flusslimitierter Atemzüge, und dem Schweregrad einer obstruktiven schlafbezogenen Atmungsstörung.

Die wichtigste Erkenntnis dieser Untersuchung ist, dass die Begrenzung des Inspirationsflusses nicht unbedingt mit einer Zunahme der Atemanstrengung verbunden ist. Die Atemanstrengung unterscheidet sich in den verschiedenen Schlafstadien und verhält sich bei Gesunden und Patienten mit milder und schwerer OSA unterschiedlich. 
Eine erhöhte inspiratorische Anstrengung ist ein Merkmal der schweren, aber nicht der milden OSA, und scheint unabhängig von der Flusslimitation zu sein. Die Rolle von intrathorakalen Druckschwankungen, die nichts mit Obstruktionen und Flusslimitationen zu tun haben, sollte daher weiter untersucht werden.

Die Ergebnisse dieser Untersuchung legen nahe, sich in der Therapie der OSA in erster Linie auf die Schlafphasen N2 und N3 zu konzentrieren, da hier der negative intrathorakale Druck am meisten erhöht ist.
title: Niche separation of Clausocalanus species in the Mediterranean Sea and in the Atlantic Ocean
Creators: name: Marco, Aurea Peralba
Publisher: name: The Open University
Year: 2008

description: This thesis represents an integrated study of the ecology and reproductive biology of Clausocalanus, a planktonic copepod genus that is widespread in oceanic and coastal regions but still poorly investigated. Principal aim of this study was characterizing the niches of eight congeneric species on the basis of investigations conducted at different space and time scales in the Mediterranean Sea and in the Atlantic Ocean. The combined results of field surveys and experiments showed that Clausocalanus species were characterized by different ecological and reproductive traits. Along ecological gradients of temperature and autotrophic biomass, the niches were clearly defined and separated in small (C. paululus, C. pergens, and C. furcatus) and large (C. lividus and C. mastigophorus) species, while they largely overlapped in medium-sized species (C. parapergens, C. jobei, and C. arcuicornis). Clausocalanus presents a unique reproductive feature among planktonic copepods, since its species have two different egg-laying modes: small and medium-sized species are sac-spawners while the large species are broadcast spawners. The first data on specific sex ratio, embryo viability and hatching success were here provided for Clausocalanus wild populations. Egg production rates of broadcaster species were more than three times higher than those of sac-spanwers. Embryo viability was low in broadcast spawners and very high in sac-spawners. Despite the two groups had similar secondary production, broadcast spawners had lower recruitment, which could contribute to their lower abundance at sea. A nuclear vital probe revealed that eggs of successive clutches were fertilized even in the absence of males, suggesting that re-mating is not necessary in this genus. The results of this thesis highlight the relevance of Clausocalanus in marine zooplankton communities and the distinctness of its species, towards a better understanding of niche differentiation among congeners in the epipelagos.

Evidence for an Exotic Baryon State, Theta+(1540), in Photoproduction Reactions from Protons and Deuterons with CLAS

description: CLAS photoproduction data on deuterium and hydrogen targets have been analyzed in a search for an exotic baryon state with strangeness S=+1, the Θ^+ (originally named the Z^+). This resonance was predicted recently in theoretical work based on the chiral soliton model as a lowest mass member of an anti-decuplet of 5-quark states. The reaction gamma d --> pK^-K^+n, which requires a final state interaction inside the deuteron, was used in the analysis of deuteron data. In the analysis of proton data, the reaction gamma p --> pi^+K^-K^+n was studied. Evidence for the Θ^+ state is found in both analyses in the invariant mass distribution of the nK^+. Our results are consistent with previously reported results by LEPS/Spring-8 collaboration (Japan), and by the ITEP (Moscow) group.

Язык «Сфирали» как  инструмент преодоления  двоичного восприятия
Creators: name: Басаргин, Олег Сергеевич
Publisher: name: Zenodo
Year: 2025

description: Настоящая статья исследует устройство «Сфираль» как язык многомерности, способный преодолеть ограничения плоскостного восприятия, описанного аллегорией Платона о пещере. Светотени, создаваемые устройством, интерпретируются как символы, которые находят аналогии в древних письменностях, таких как Чероки, Буквица, шумерская клинопись, ронго-ронго и цзягувэнь. Дешифровка этих символов позволяет выйти за пределы двоичной логики, укоренённой в сознании, обществе и технологиях, и достичь многомерной реальности, где время, сознание и культура сливаются в гармоничное единство. Исследование демонстрирует потенциал языка «Сфирали» для создания новых технологий, таких как конвергентный язык программирования, и применения в биологии через концепцию Sfiral DNA. Результаты подчёркивают необходимость дальнейших исследований для реализации перехода к новой реальности, обозначенной как Новая Земля и Новое Небо.

description: Moldova's transition from planned to market economy required a total reconstruction of the tax system structure, particularly: taxes, tax administration and legislation of tax matters. However, in practice, Moldovan tax system (MTS) was not able to solve the multitude of problems that occurred. This system is unfair as it hampers economic growth, applying half measures, and does not ensure state programs and services are efficient especially on agriculture sector. The legal economy was substituted with “shadow one” that gets alarming proportions until present. The largest share in total informal employment holds agricultural sector, and the main contribution belongs to households. Due to the specificity of this type of employment, 80% of informally employed people are working in rural areas, which is detrimental for an economy where about 55% of population lives in rural areas and almost 28% are employed in agriculture. The paper aims to reveal the weaknesses and strengths of MTS, related to evelopment on agriculture sector, considering several suggestions for most appropriate taxing culture changes (e.g. personalized VAT reform based on successful experience of Latin America).
