Abstract

We proposed a semi-parametric estimation procedure in order to estimate the parameters of a max-mixture model and also of a max-stable model (inverse max-stable model) as an alternative to composite likelihood. A good estimation by the proposed estimator required the dependence measure to detect all dependence structures in the model, especially when dealing with the max-mixture model. We overcame this challenge by using the F-madogram. The semi-parametric estimation was then based on a quasi least square method, by minimizing the square difference between the theoretical F-madogram and an empirical one. We evaluated the performance of this estimator through a simulation study. It was shown that on an average, the estimation is performed well, although in some cases, it encountered some difficulties. We apply our estimation procedure to model the daily rainfalls over the East Australia.

Abstract

Dysregulation in neutrophil extracellular trap (NET) formation and degradation may play a role in the pathogenesis and severity of COVID-19; however, its role in the pediatric manifestations of this disease, including multisystem inflammatory syndrome in children (MIS-C) and chilblain-like lesions (CLLs), otherwise known as "COVID toes,"remains unclear. Studying multinational cohorts, we found that, in CLLs, NETs were significantly increased in serum and skin. There was geographic variability in the prevalence of increased NETs in MIS-C, in association with disease severity. MIS-C and CLL serum samples displayed decreased NET degradation ability, in association with C1q and G-actin or anti-NET antibodies, respectively, but not with genetic variants of DNases. In adult COVID-19, persistent elevations in NETs after disease diagnosis were detected but did not occur in asymptomatic infection. COVID-19-affected adults displayed significant prevalence of impaired NET degradation, in association with anti-DNase1L3, G-actin, and specific disease manifestations, but not with genetic variants of DNases. NETs were detected in many organs of adult patients who died from COVID-19 complications. Infection with the Omicron variant was associated with decreased NET levels when compared with other SARS-CoV-2 strains. These data support a role for NETs in the pathogenesis and severity of COVID-19 in pediatric and adult patients.

Abstract

Transcriptomic, proteomic and immune repertoire profiling reveals distinct peripheral features of MIS-C and pediatric COVID-19, including elevated soluble spike protein levels, more pronounced type II IFN-dependent gene expression and a higher B cell mutation rate in patients with MIS-C.Pediatric Coronavirus Disease 2019 (pCOVID-19) is rarely severe; however, a minority of children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) might develop multisystem inflammatory syndrome in children (MIS-C), with substantial morbidity. In this longitudinal multi-institutional study, we applied multi-omics (analysis of soluble biomarkers, proteomics, single-cell gene expression and immune repertoire analysis) to profile children with COVID-19 (n = 110) and MIS-C (n = 76), along with pediatric healthy controls (pHCs; n = 76). pCOVID-19 was characterized by robust type I interferon (IFN) responses, whereas prominent type II IFN-dependent and NF-kappa B-dependent signatures, matrisome activation and increased levels of circulating spike protein were detected in MIS-C, with no correlation with SARS-CoV-2 PCR status around the time of admission. Transient expansion of TRBV11-2 T cell clonotypes in MIS-C was associated with signatures of inflammation and T cell activation. The association of MIS-C with the combination of HLA A*02, B*35 and C*04 alleles suggests genetic susceptibility. MIS-C B cells showed higher mutation load than pCOVID-19 and pHC. These results identify distinct immunopathological signatures in pCOVID-19 and MIS-C that might help better define the pathophysiology of these disorders and guide therapy.

Abstract

Background: Hantavirus cardiopulmonary syndrome (HCPS) is caused by new world hantaviruses, among which Andes hantavirus (ANDV) is endemic to Chile and Southern Argentina. The disease caused by ANDV produces plasma leakage leading to enhanced vascular permeability and has a high case fatality rate (35%), mainly due to respiratory failure, pulmonary edema and myocardial dysfunction, hypoperfusion and shock. Host sociodemographic and genetic factors might influence the course and outcome of the disease. Yet, they have not been thoroughly characterized. Aim: To evaluate sociodemographic factors as risk factors in severity of HCPS. Patients and Methods: Study period: 2004-20013, attending in eight collaborative centers, etiological diagnosis was performed by serology or molecular biology, mild and severe HCPS were compared.139 Chilean patients were analyzed, 64 (46%) with severe disease among which 12 (19 %) died. Results: European ethnicity had 5,1 times higher risk than Amerindian ethnic group to develop a severe HCPS, greater seriousness that was also associated with an urban residence. Conclusion: It was observed that ethnicity and type of residence were significant risk factors for HCPS severity. Hypotheses explaining these findings are discussed.

Abstract

Background Longitudinal cohort studies provide important information about the clinical effectiveness of an intervention in the routine clinical setting, and are an opportunity to understand how a population presents for treatment and is managed. Methods INTEREST IN CD2 (NCT01753349) is a prospective, international, 3-year, longitudinal, observational study following the course of adult idiopathic cervical dystonia (CD) treated with botulinum neurotoxin type A (BoNT-A). The primary objective is to document long-term patient satisfaction with BoNT-A treatment. Here we report baseline data. Results This analysis includes 1036 subjects (67.4% of subjects were female; mean age was 54.7 years old; mean TWSTRS Total score was 31.7). BoNT-A injections were usually given in line with BoNT-A prescribing information. The most commonly injected muscles were splenius capitis (87.3%), sternocleidomastoid (82.6%), trapezius (64.3%), levator scapulae (40.9%) and semispinalis capitis (26.9%); 35.5% of subjects were injected using a guidance technique. Most subjects (87.8%) had been previously treated with BoNT-A (median interval between last pre-study injection and study baseline was 4 months); of these 84.8% reported satisfaction with BoNT-A treatment at peak effect during their previous treatment cycle and 51.5% remained satisfied at the end of the treatment. Analyses by geographical region revealed heterogeneity in the clinical characteristics and BoNT-A injection practice of CD subjects presenting for routine treatment. Conclusions These baseline analyses provide sizeable data regarding the epidemiology and clinical presentation of CD, and demonstrate an international heterogeneity of clinical practice. Future longitudinal analyses of the full 3-year study will explore how these factors impact treatment satisfaction.

Abstract

National audience; Dans le contexte actuel de baisse continue de la consommation de viande chevaline en France, ces recherches s’intéressent aux freins et leviers mobilisables pour développer ce marché. Elles s’appuient sur une revue de littérature, le traitement de base de données préexistantes et des enquêtes qualitatives et quantitatives auprès du grand public et de chefs cuisiniers. Le premier levier identifié est lié à la visibilité et disponibilité de l’offre, afin d’accroitre la fréquence d’achat des consommateurs actuels. Un second levier s’appuie sur les caractéristiques de la viande de cheval qui peuvent lui permettre de répondre aux enjeux actuels de durabilité de de l’alimentation. Enfin, parmi les Français non-consommateurs de viande chevaline, 15% seraient prêts à consommer de la viande chevaline s’ils en avaient l’occasion, majoritairement chez des proches ou au restaurant. Développer la présence de viande chevaline en restauration commerciale apparait donc comme un moyen pertinent de familiariser de nouveaux consommateurs potentiels à ce produit. Ceci implique de pallier le manque de connaissances des chefs cuisiniers envers ce produit et le manque d’un répertoire de recettes.

Abstract

National audience; Les équidés, de par leur nature et leur place au sein de la société, ont un rôle à jouer dans le contexte de prise de conscience écologique actuel. Ils sont présentés dans ce projet comme acteurs multifonctionnels, rendant des services environnementaux. Ces derniers sont nommés « atouts verts ». Afin de centraliser les données disponibles à ce sujet au sein des différents pays Européens, l’outil ODEFI (Outil de collecte de Données Environnementales des Filières équines Internationales) a été développé. Il donne lieu à une base de données permettant d’améliorer notre connaissance sur les atouts verts des filières équines européennes. En 2020-2021, huit pays ont été enquêtés (France, Belgique, Suède, Croatie, Pologne, Slovénie, Roumanie et Allemagne) au travers de 58 indicateurs.Une grande hétérogénéité entre pays apparait concernant la disponibilité des données. Néanmoins, une première typologie peut être dessinée avec trois groupes de pays : (1) le cheval, outil agricole en élevage extensif ; (2) le cheval sportif ou de loisir, associé à un regain d’intérêt pour sa force motrice ; (3) un intermédiaire entre les deux situations précédentes. La collecte se poursuit auprès d’autres pays afin d’affiner les résultats et de dresser un panorama des atouts verts européens le plus complet possible.

Abstract

Resumen Introducción: El síndrome cardiopulmonar por hantavirus (SCPH) es causado en Chile y en el sur de Argentina por el Andes hantavirus (ANDV), el que es endémico en esta zona. La enfermedad causada por ANDV produce un aumento de permeabilidad vascular y filtración de plasma con una alta tasa de letalidad (35%), debido principalmente a insuficiencia respiratoria por edema pulmonar y al desarrollo en los casos graves de compromiso miocárdico, hipoperfusión y shock. Aunque se sabe que los factores socio-demográficos del hospedero pueden influir en el curso y el resultado de la enfermedad, estos no se han caracterizado previamente en la población chilena. Objetivo: Evaluar la relación entre los factores socio-demográficos y la gravedad del SCPH. Pacientes y Métodos: Período de análisis 2004-20013, pacientes atendidos en ocho centros colaboradores, diagnóstico etiológico serológico o por biología molecular, se comparan SCPH leve y grave. Se analizaron 139 pacientes chilenos, 64 (46%) con enfermedad grave, entre los cuales 12 murieron (19%). Resultados: La etnia europea tuvo un riesgo 5,1 veces mayor de desarrollar un SCPH grave que la etnia amerindia, gravedad mayor que también se asoció a una residencia urbana. Conclusiones: Se observó una asociación estadísticamente significativa entre etnia, lugar de residencia y evolución de SCPH. Se discuten hipótesis que expliquen estos hallazgos.

Background: Hantavirus cardiopulmonary syndrome (HCPS) is caused by new world hantaviruses, among which Andes hantavirus (ANDV) is endemic to Chile and Southern Argentina. The disease caused by ANDV produces plasma leakage leading to enhanced vascular permeability and has a high case fatality rate (35%), mainly due to respiratory failure, pulmonary edema and myocardial dysfunction, hypoperfusion and shock. Host sociodemographic and genetic factors might influence the course and outcome of the disease. Yet, they have not been thoroughly characterized. Aim: To evaluate sociodemographic factors as risk factors in severity of HCPS. Patients and Methods: Study period: 2004-20013, attending in eight collaborative centers, etiological diagnosis was performed by serology or molecular biology, mild and severe HCPS were compared.139 Chilean patients were analyzed, 64 (46%) with severe disease among which 12 (19 %) died. Results: European ethnicity had 5,1 times higher risk than Amerindian ethnic group to develop a severe HCPS, greater seriousness that was also associated with an urban residence. Conclusion: It was observed that ethnicity and type of residence were significant risk factors for HCPS severity. Hypotheses explaining these findings are discussed.

Abstract

International audience; In the context of leisure sports, many people are leaving sporting clubs to self- organize (Chillet 2019), alone or with other consumers (Heinonen, Campbell, and Ferguson 2019). This poses a problem for clubs and sport federations as it leads to a decrease in members’ number (Eslan, Vial, Costa and Rollet 2019). This presentation will review the literature on value co- creation (VCC) / prosumption to understand (i) what determines consumer participation in the produc- tion process and (ii) whether the service offering of a firm using value co-creation could substitute for consumer self-organization. We first present the determinants and consequences of consumer participa- tion in a co-creation process with a business or among consumers. This part highlights the crucial role of value in customer decisions, introducing the value creation process described in the second part. Thirdly, we propose an integrative approach of value co-creation in the choice of service production applied to self-organized activities. Prosumption, the act of consuming and producing, allows con- sumers to personalize their products or services. If this process is carried out in relation with several actors (professionals, consumer groups, organizations or individuals), we speak of value co- creation, with personalization often mainly managed by companies. Leclercq, Hammedi, and Poncin (2016) defines co-creation as “a joint process during which value is reciprocally created for each actor (individu- als, organizations or networks)” to interact and exchange resources. In line with Heinonen, Jaakkola, and Neganova (2018), we posit that C to C co- creation depends on the value inherent in the interaction between the customer and the provider, but also emerging from the interactions between customers. Prior research has shown the importance of motivations for en- gaging in prosumption. Its antecedents are rooted in either the cus- tomer’s buying experience or the decision-making process. Carrying out a project of prosumption requires knowledge, skills, community seeking and time (Wolf, Albinsson, and Becker 2015). Heinonen et al. (2018) show a range of drivers of C to C interactions induced by firms, situations or customers (motivations), these are either for dif- ferent social or personal benefits. Benefits are thus emotional value or reinforcement of affective (i.e., emotional) and network (i.e., so- cial) values for focal clients through the playful and ludic behav- iors of other clients (Kim, Byon, and Baek 2019). In sport, C to C co-creation studies show that the presence of interactions motivates participants, thereby enhancing consumer experience (Kolyperas, Maglaras, and Sparks 2019). Moreover, willingness to participate to future co-creation activities depends on past experience, thus on the consequences of the process influenced by moderators such as trust or demographic determinants. These moderators act either before, during or after VCC process. Furthermore, in line with Aurier, Evrard, and N’Goala (2004), we integrate overall perceived value as a consequence of VCC pro- cess. The sacrifices made and the benefits perceived constitute over- all perceived value. It goes beyond the profit to cost ratio shown by Xie, Bagozzi, and Troye (2008), which is not only an economic benefit or cost. However, if this overall value is in favour of sac- rifice, consumers will turn to outsourcing rather than prosumption. The relationship between value creation and process outcomes then underlines the central role of value in the consumer’s decision to par- ticipate in production, especially under the influence of overall per- ceived value, as some components of value seem more decisive than others in consumer participation. The absence of certain components may lead to the co-creation process being halted. Our position herein is to analyze value creation resulting from consumer interactions and components of this value as preferential judgments. We propose an integrative picture of the different dimensions of value based on Holbrook (2002) and Aurier et al. (2004). The above criteria have thus resulted in a typology that breaks down the value into four main components: instrumental, hedonic, social and spiritual value. We enrich the spiritual value component with holistic value (Lai 1995) which is the perceptual benefits that depends on how compatible or coherent this consumption is perceived by the consumer. Furthermore, we support Medberg and Heinonen (2014) research on the influence of invisible values. These authors consider that value creation emerges either by the companies, in the relation- ship between companies and customers, or by the customer alone. Thus, spiritual value also refers to shared moral value as the adequa- cy between customers’ own moral standards and the standards of the other stakeholder. Corneloup (2016) in climbing activity shows an opposition of practitioners according to their practice style. Califor- nian-style practitioners focused on their relationship with nature and do not wish a more competitive form motivated by quick climbing on an artificial wall. Moreover, responsibility value is defined as the firm’s “practice of responsibility and integrity towards its custom- ers”. Both values relate indirectly to how the companies operate, then they can be integrated as intrinsic others-orientated approach. For heritage value, based on the history of the customer and its rela- tives with the company, we consider it more as social value, as heri- tage exclusively depends on consumption experience of the customer and its relatives. Like the relationship value, defined as a long-term relationship between actors, these values are based specifically on the clients’ own logic. This critical qualitative analysis of VCC literature tries to un- derstand why consumers do engage in VCC with companies or in C to C. The analysis of value components highlights invisible values that may explain why consumers prefer to co-create with others than with firms. Indeed, when consumers do not find all value dimensions they are looking for in the professional structures, then they drop out of professional structures. Future researches should focus on supply and demand adequacy to restructure service offer for companies, and confirm the integrative approach of value in the analysis of consum- ers’ participation to co- creation. Firms have leverage if they take into account the value dimensions in the co- creation process in order to recapture consumers organized in C to C, but also, on a critical perspective, to find out what occurs when consumers are not able to co-create, do not want or see value in the process.

Abstract

Background Patients with cervical dystonia (CD) typically require regular injections of botulinum toxin to maintain symptomatic control. We aimed to document long-term patient satisfaction with CD symptom control in a large cohort of patients treated in routine practice. Methods This was a prospective, international, observational study (NCT01753349) following the course of adult CD treated with botulinum neurotoxin type A (BoNT-A) over 3 years. A comprehensive clinical assessment status was performed at each injection visit and subjects reported satisfaction in two ways: satisfaction with symptom control at peak effect and at the end of treatment cycle. Results Subject satisfaction remained relatively stable from the first to the last injection visit. At 3 years, 89.9% of subjects reported satisfaction with symptom control at peak effect and 55.6% reported satisfaction with symptom control at end of treatment cycle. By contrast, objective ratings of CD severity showed an overall reduction over 3 years. Mean ± SD Toronto Western Spasmodic Rating Scale (TWSTRS) Total scores (clinician assessed at end of treatment cycle) decreased from 31.59 ± 13.04 at baseline to 24.49 ± 12.43 at 3 years (mean ± SD reduction from baseline of − 6.97 ± 11.56 points). Tsui scale scores also showed gradual improvement; the percent of subjects with a tremor component score of 4 reduced from 12.4% at baseline to 8.1% at 3 years. Conclusions Despite objective clinical improvements over 3 years, subject satisfaction with symptom control remained relatively constant, indicating that factors other than symptom control also play a role in patient satisfaction.

Abstract

Long neglected, back country sport can play an important role in territorial development. Based on the examples of equestrian and hunting leisure, a grid of structuring and destructuring effects in terms of development has been applied by retaining economic base and territorial resource as main theoretical frameworks. From specific investigations in Normandy (for riding) and in height study areas (for hunting), the results tend to show the basic nature of the expenses related to these activities (including substituting other external forms of leisure outside territories) on the basis of identity or cultural resources., Longtemps négligées, les Activités Physiques de Pleine Nature peuvent jouer un rôle important dans le développement territorial. Partant des exemples des loisirs équestres et cynégétiques, une grille des effets structurants et déstructurants en termes de développement territorial a été appliquée en retenant les théories de la base économique et de la ressource territoriale comme cadres théoriques principaux. À partir d’enquêtes spécifiques menées en Normandie (pour l’équitation) et dans huit zones d’étude (pour la chasse), les résultats tendent à montrer le caractère moteur des dépenses liées à ces activités (y compris en substituant à d’autres formes de loisirs externes aux territoires) en s’appuyant sur des ressources identitaires ou culturelles.

[Departement_IRSTEA]Territoires [ADD1_IRSTEA]Adaptation des territoires au changement global; International audience; This article presents the equine industry and its segments. It highlights the diversity that characterizes the horse industry on many levels. This diversity is firmly linked to the presence of equine in diverse areas, to varied human resources and to a constant ability to adapt horse uses to the changes in society. This occurs in spite of the elitist and non-agricultural image of horses that remains in place even though it is obsolete today. The equine sector is a source of significant positive externalities on agricultural and territorial levels, in terms of economic, social, cultural and environmental effects. Because of the recent but nonetheless important development of the equine sector, many research topics remain to be explored. Even if the diversity that characterizes the horse industry can affect its transparency, there is no doubt that it is an asset that can be used on many levels, giving the horse industry its adaptability and its plurality of externalities.; Cet article présente un état des lieux de la filière équine, parcourant les segments qui la composent et soulignant la diversité qui la caractérise à de nombreux niveaux. Cette diversité est liée à la présence des équidés au sein de territoires variés, à des ressources humaines diverses et à une constante adaptation des usages du cheval aux évolutions de la société. L'image élitiste et non-agricole du cheval est obsolète et la diversité de la filière équine est source d'externalités largement positives aux niveaux agricole et territorial, en termes économiques, sociaux, culturels et environnementaux. Du fait d'un développement assez récent mais néanmoins important de la filière équine, nombre de sujets de recherche restent à explorer. Il est toutefois certain que la diversité qui caractérise cette filière, bien que pouvant pénaliser sa visibilité, est un atout à exploiter à de nombreux niveaux, lui conférant capacité d'adaptation et pluralité de retombées.

Abstract

This work reports on the influence of treatment conditions on the olive stones for adsorptive lead(II) ions. The olive stones were treated with acidic or alkaline solutions at various concentrations and contact time. The structure and surface properties of the resulting biosorbents were characterized by surface pH, Boehm's titration and N2 adsorption-desorption isotherms. The olive stones sample, treated with HNO3, possess the highest surface oxygen containing functional groups (3.76 mmol/g), surface area (198 m2/g) and pore volume (0.081cm3/g) and the more adsorption capacity to the lead ions. The adsorption efficiency was higher for treated of olive stones with HNO3 than for treated with KOH. However, the weight loss of the adsorbent products was important with HNO3 treatment. It was also found that the time to reach equilibrium takes less 15 minutes. The effect of contact time, initial concentrations of adsorbate, ionic strength and adsorbent dose on the uptake of lead was studied in batch experiments. The kinetic data were fitted to the pseudo-first order and pseudo-second order, and follow closely the pseudosecond order model. Equilibrium adsorption of Pb(II) were analyzed by the Langmuir, Freundlich and Redlich-Peterson isotherm models. The results reveal that the Redlich-Peterson isotherm models fitted the data.

Abstract

In this paper, we consider isotropic and stationary max-stable, inverse max-stable and max-mixture processes X = (X (s)) s ∈ R 2 and the damage process D X ν = | X | ν with 0 < ν < 1 / 2. We study the quantitative behaviour of a risk measure which is the variance of the average of D X ν over a region A ⊂ R 2 . This kind of risk measure has already been introduced and studied for some max-stable processes in Koch [Spatial risk measures and applications to max-stable processes, Extremes 20(3) (2017), pp. 635–670].

Abstract

Background and purpose: Hypertrophy/signal hyperintensity and/or gadolinium enhancement of plexus structures on magnetic resonance imaging (MRI) are observed in two‐thirds of cases of typical chronic inflammatory demyelinating polyneuropathy (CIDP). The objective of our study was to determine the additional benefit of plexus MRI in patients referred to tertiary centers with baseline clinical and electrophysiological characteristics suggestive of typical or atypical CIDP. Methods: A total of 28 consecutive patients with initial suspicion of CIDP were recruited in nine centers and followed for 2 years. Plexus MRI data from the initial assessment were reviewed centrally. Physicians blinded to the plexus MRI findings established the final diagnosis (CIDP or neuropathy of another cause). The proportion of patients with abnormal MRI was analyzed in each group. Results: Chronic inflammatory demyelinating polyneuropathy was confirmed in 14 patients (50%), as were sensorimotor CIDP (n = 6), chronic immune sensory polyradiculoneuropathy (n = 2), motor CIDP (n = 1) and multifocal acquired demyelinating sensory and motor neuropathy (n = 5). A total of 37 plexus MRIs were performed (17 brachial, 19 lumbosacral and 8 in both localizations). MRI was abnormal in 5/37 patients (14%), all of whom were subsequently diagnosed with CIDP [5/14(36%)], after an atypical baseline presentation. With plexus MRI results masked, non‐invasive procedures confirmed the diagnosis of CIDP in all but one patient [1/14 (7%)]. Knowledge of the abnormal MRI findings in the latter could have prevented nerve biopsy being performed. Conclusion: Systematic plexus MRI in patients with initially suspected CIDP provides little additional benefit in confirming the diagnosis of CIDP. [ABSTRACT FROM AUTHOR]

Abstract

Removal of manganese (II) from drinking water by aeration process using an airlift reactor, DOI: 10.1016/j.jwpe.2017.01.010 URL: http://www.sciencedirect.com/science/article/pii/S2214714416303464 Filiació URV: SI Memòria, The objective of this study is the removal of soluble manganese Mn(II) from drinking water by aeration process in order to oxidize it into insoluble manganese dioxide MnO2 using a Split-Rectangular Airlift Reactor (SRAR). The description of the global hydrodynamics, liquid mixing and gas-liquid mass transfer properties of the SRAR were presented in previous works and were compared to data and correlations in the literature. The effects of operating conditions were investigated, including initial pH, Mn(II) concentrations and amount of MnO2 particles. The major findings are that the oxidation of Mn(II) corresponds to a kinetically-slow reaction that is strongly pH-dependent. The kinetic data show an autocatalytic behaviour due to the oxidation of Mn(II) on the MnO2 surface, which allows the conversion to go to completion. This behaviour is confirmed by the addition of MnO2 fine particles that increase drastically the reaction rate. At high initial Mn(IV) concentrations, the kinetic law was shown to be pseudo-first order in Mn(II), with an apparent kinetic constant depending on the initial amount of Mn(IV) compounds. This constant was fitted by a linear model as a function of Mn(IV) concentration. This model was shown to be in good agreement with experimental data. Comparing with other techniques, aeration is an efficient process because it gives us a removal efficiency of 90% in less than 40 min at pH 9.5 and initial soluble Mn(II) and insoluble Mn(IV) concentrations between 5 and 20 and 0–500 mg/L, respectively, while avoiding the drawbacks of strong oxidizers and biological oxidation processes. A model able to predict quantitatively Mn removal as a function of pH, initial Mn(II) and initial Mn(IV) concentrations is also developed.

Abstract

From the time they became domesticated, horses have fulfilled roles imposed by human societies. Changing economies, societies and technologies have transformed the predominant roles held by horses in human life. They are now overwhelmingly employed in improving the quality of human life. Across Europe the status of the horse is evolving as ridership grows, and these changes create new economic opportunities for equine and rural enterprises. The 20 chapters focus on new or developing sectors of the equine economy through sections devoted to impact studies, economic opportunities, socio-economic challenges, social economy, governance issues, sustainable development, the case of horse meat and national reports about the horse in the national economies. The topics range from equine tourism, alternative medicine for competition horses, and the use of social media, through to what may be the most complete guide to the scientific production of horse meat to be published so far. Each chapter provides a glimpse of where the equine economy may go in the 21st Century, based upon the research of experts in their field. No one can predict the future, but the authors give us insight into some of the cutting edge trends which are shaping the nature of the equine world and producing the New Equine Economy of the 21st Century.

Abstract

The Hilbert scheme X[3] of length-3 subschemes of a smooth projective variety X is known to be smooth and projective. We investigate whether the property of having a multiplicative Chow–Künneth decomposition is stable under taking the Hilbert cube. This is achieved by considering an explicit resolution of the rational map X3⇢X[3]. The case of the Hilbert square was taken care of in Shen and Vial [Mem. Amer. Math. Soc.240(1139) (2016), vii+163 pp]. The archetypical examples of varieties endowed with a multiplicative Chow–Künneth decomposition is given by abelian varieties. Recent work seems to suggest that hyperKähler varieties share the same property. Roughly, if a smooth projective variety X has a multiplicative Chow–Künneth decomposition, then the Chow rings of its powers Xn have a filtration, which is the expected Bloch–Beilinson filtration, that is split.
