The present hydrogeological study was carried out in the complex basement zone (Dabakala department, North-Central Côte d'Ivoire). Indeed, in this area, the population faces a real problem with the drinking water supply during the dry season. The aim of this study is to carry out a spatial characterization of groundwater potentialities in order to establish productive boreholes in the division. Ten decision criteria were developed and then aggregated. The methodology consisted in building a database based on these criteria, using remote sensing and GIS techniques. These criteria applied multi-criteria decision analysis (MCDA) using the Hierarchical Analytical Process (HAP) for their weighting. The resulting groundwater potential map was validated using the sensitivity trend curve technique. Ultimately, the results indicate that approximately 35% of the division’s area has strong to very strong groundwater potential.

ABSTRACT

The results of the research based on the data obtained show that in the process of implementing the ceremony of rejecting the dance of Dakdeng dance present in the middle of the implementation becomes one of the important parts that must be carried out because the Dakdeng dance becomes a means of entry of supernatural spirits called Mambang which is the spirit of the ancestors of their descendents . Mambang's spirits entering the body of the family and community will dance during the process of rejecting reinforcements. There are differences in the movements and character of the Dakdeng dance between one dancer to the other. Because every Mambang who possesses the body of a family or a number of people who become dancers has a different character. Different character can be seen from Mambang Buaya who is angry when he feels disturbed, Mambang Knight is able to control emotions when there are other Mambang who unintentionally interfere, Blind Mambang has a sensitive mood, Mambang Leaders have a strict, hard and responsible nature, Mambang Penangis the loner and likes to cry, Mambang Macan is quiet and calm, Mambang Jelita is cheerful and encourages the other Mambang to dance, Mambang Galak is very angry when he sees the audience recording with his cellphone camera, Mambang Iba is gentle and a loner, Mambang Berdembah covers the genitals and is happy approaching with other Mambang spirits, Shy Mambang does not want to show his face in public and cover it with a scarf. Judging from the different character of Mambang, the movements performed are also different according to the wishes of each Mambang.

"The article is dedicated to the development of the flute acoustic and tuning systems during the 18th-19th centuries. Based on the analysis of J. J. Quantz's treatise »Versuch einer Anweisung, die Flöte traversiere zu spielen« and the flute of its construction with two enharmonically unequal keys Es and Di s, the intonation and technological features of using pure tuning system in playing an instrument are revealed. Following Quantz’s ideas was another German musician, the Leipzig master instrument maker J. G. Tromlitz. He strongly recommended maintaining the dominant position of the pure tuning system while performing on the flute. The defining stage in the development of the flute design and the establishment of the well-tempered tuning system as the basis of its acoustic features was the reform of T. Boehm. The models of the inverse conical bore flute with open ring keys (1832) and the cylindrical flute with flap keys (1847) created step-by-step give evidence of the evolution of T. Boehm's views on expanding the sound dynamics and improving the intonation capabilities of the instrument.

Published: July 2022

Los estudios de emisores y sus procesos productivos representan una de las aristas fundamentales para la comprensión y redefinición de la comunicación, en tanto aportan elementos sobre la dinámica informativa de los medios de difusión masiva. Sus referentes teóricos-metodológicos resultan válidos para evaluar las prácticas comunicativas que realizan otros actores sociales en diferentes espacios de socialización. De manera particular, la universidad es una institución pública que asume la comunicación como eje estratégico de su gestión, ayuda a definir los propósitos y funciones, y contribuye a la socialización de sus procesos y resultados. Por esta razón, el propósito de este estudio es analizar las rutinas productivas del Departamento de Comunicación Institucional de la Universidad de Camagüey de Cuba. Se emplean métodos teóricos y empíricos (observación, entrevista y análisis de contenido), imprescindibles en la obtención de los resultados. Las principales conclusiones del estudio demuestran que los nuevos desafíos tecnológicos, los factores estructurales-organizativos y el contexto sociopolítico inciden en las formas de selección, producción, difusión y consumo de la información.

abordaje antropológico de lo no lucrativo
Authors: Salvade Romina Cecilia , Keheyan Karen
Published: July 2022

Este artículo se propone abordar lo no lucrativo en clave antropológica, proyectando el enfoque dialéctico hacia instituciones que se definen como sin fines de lucro y se ubican en dos ciudades medias del centro bonaerense. El desarrollo comprende la identificación y tipificación de categorías nativas mediante las cuales se invoca lo no lucrativo como bandera con la que se emblematiza al desinterés. Las categorías son recuperadas de un corpus de entrevistas no estructuradas realizadas entre 2015 y 2019. La propuesta analítica se nutre de la conceptualización marxista de trabajo vivo y trabajo muerto con objeto de interrogar qué valores de cambio subyacen a la emblematización de lo no lucrativo.
productividad y el ocio mediados por objetos
Authors: Papez Boris
Published: July 2022

En 2020 la pandemia por covid–19 y las políticas de confinamiento trastocaron abruptamente las actividades cotidianas y laborales de las personas. Nuestro objetivo es indagar los problemas que ello generó en el día a día y las estrategias que los sujetos pusieron en juego para reorganizar sus rutinas. La metodología se basó en el estudio cualitativo de diarios auto–etnográficos y entrevistas a estudiantes universitarios basados en sus prácticas culturales durante el aislamiento social. A partir de su análisis observamos que uno de los principales problemas de pasar más tiempo en casa fue la dificultad para separar momentos de productividad y de ocio por desarrollarse todas las actividades en un mismo lugar, lo que devino en una tendencia hacia la hiperactividad. Así, sostenemos que el uso de los objetos (computadoras, celulares, libros, instrumentos musicales, etcétera) fue central para reorganizar las rutinas por su capacidad para establecer límites simbólicos entre la productividad y el ocio, sustituyendo en esta función a los espacios.

Partiendo de la idea, largamente discutida y elaborada en el ámbito de las Teorías de la Fotografía y de la Cinematografía, caso de Siegfried Kracauer, Edgar Morin, Roland Barthes y otros autores - así también de algunas experiencias realizadas por la directora Agnès Varda -,  de que la imagen fotográfica supone un puente entre la realidad objetiva y el mundo subjetivo, se plantea y  lleva cabo una secuencia de experimentos prácticos con relación a la lectura, observación y dinamización de algunas fotografías de autor, mediante la aplicación de diversos dispositivos mentales y técnicos – cámaras de teléfonos inteligentes -, cuyos resultados arrojan interesantes datos acerca del surgimiento de nuevas interpretaciones personales y narrativas, más allá de la realidad captada objetiva y mecánicamente por la cámara. Estos resultados asumen la forma de diversas piezas audiovisuales, de las que aquí se incorpora una de ellas, que constituyen en sí mismas nuevas creaciones, nuevas actitudes estéticas en relación, pero también al margen de la obra primigenia.
Del álbum fotográfico al ensayo audiovisual: Memoria y narrativas autobiográficas en la Universidad para Mayores
Authors: Cruz-Carvajal Isleny , Fernández-Hoya Alberto
Published: July 2022

Este trabajo selecciona y estudia una serie de piezas audiovisuales surgidas en el seno del Taller de Cine que actualmente desarrollamos en la Universidad para los Mayores. En esta experiencia pionera, dentro de los cursos que oferta la Universidad Complutense de Madrid, el alumnado realiza una creación que sigue los parámetros experimentales del ensayo audiovisual. La práctica ensayística aparece aquí como una herramienta privilegiada que los nuevos contextos digitales hacen posible y en cuya configuración juega un papel fundamental el fértil bagaje vital del alumnado. Los conceptos en los que se basa el estudio destacan aspectos comunes que comparten el álbum familiar y el ensayo audiovisual como medios de representación que expanden la experiencia individual hasta un ámbito colectivo e histórico. La memoria personal y colectiva, así como el álbum familiar, son elementos decisivos para rescatar un tiempo analógico que queda reformulado mediante narrativas, a menudo autobiográficas, caracterizadas por experiencias como la reutilización del archivo fotográfico, la exploración de la propia identidad, o el análisis de esos registros históricos e individuales con una mirada crítica, convirtiendo a nuestros mayores y su experiencia en protagonistas activos de sus respectivas obras.
Malabares de la memoria. Fotografías, recuerdos visuales, ensayos y ficciones
Authors: Arquero Blanco Isabel , Deltell Escolar Luis
Published: July 2022

En las últimas décadas, la investigación sobre la memoria ha experimentado un gran desarrollo, tanto desde la neurociencia y la psicología como desde los estudios de ciencias sociales y humanidades. El texto El bazar de la memoria (2021), de la profesora Veronica O’Keane, trata de averiguar cómo se construyen los recuerdos y, al mismo tiempo y con la misma intensidad, cómo los recuerdos moldean a los individuos. Lógicamente la metodología de los Memory Studies, que podrían traducirse como estudios de la memoria, también ha recalado en el análisis de la fotografía y la imagen en movimiento. En este número de la revista Fotocinema, titulado Recuerdos visuales fotográficos, los autores abordan el rol que desempeña la memoria en la construcción social y, sobre todo, individual. La memoria se articula como un juego de malabares entre el recuerdo y el olvido, la posmemoria y la rememoria, lo imaginado, lo deseado, la ficción y lo documentado.

Authors: Guleva D. , Balabanova M. , Miteva L. , Dourmishev L.
Published: July 2022

Lupus erythematosus is an autoimmune connective tissue disorder showing a broad spectrum of clinical manifestations.

The aim of this study was to assess the correlation of skin histology and different types of lupus erythematosus.

Materials and methods: Fifty-one skin specimens were assessed from 39 female and 12 male patients with acute, subcutaneous and chronic lupus erythematosus, diagnosed and treated in the Department of Dermatology and Venereology, Alexandrovska University Hospital for a 4-year period.

Results: Follicular hyperkeratosis, epidermal atrophy, vacuolar degeneration and interface dermatitis were the most frequently observed lesions in chronic cutaneous lupus erythematosus while diffuse hyperkeratosis, epidermal atrophy and indistinct interface dermatitis in the dermis were predominant in subacute cutaneous lupus erythematosus. Lupus tumidus, a rare intermittent variant of cutaneous lupus erythematosus, showed almost no epidermal involvement and mucin deposition in the dermis. However, in one of our lupus tumidus patients the disease progressed to a systemic form with histological changes of acute cutaneous lupus erythematosus including atrophy, dermal-epidermal smoothing and lymphocytic infiltration in the dermis. Of note, a few patients showed histological changes of urticarial vasculitis-like and rheumatic-like patterns.

Conclusion: The correlation of clinical course, histopathological findings and immunological tests are of vital importance for the correct diagnosis and follow up of patients with lupus erythematodes, thus preventing complications and improving their quality of life.
Two-Year Mortality Following a Severe COPD Exacerbation in Bulgarian Patients
Authors: Mekov E. , Petkov R. , Tsakova A. , Genova M. , Kostadinov D.
Published: July 2022

Two-year mortality in patients with COPD is expected to be between 10% and 49% depending on the investigated subgroup and specific patients’ characteristics.

Aim: To assess the two-year mortality in COPD patients following hospitalization for severe exacerbation and to describe the prognostic value of comorbidities and specific patients’ characteristics.

Materials and methods: We included 152 consecutive patients hospitalized for COPD exacerbation and signing informed consent. The Metabolic syndrome (MS), diabetes mellitus (DM), and hypovitaminosis D were diagnosed according to international guidelines. Demographic parameters (age, sex, smoking status, and the number of pack-years) were recorded. Quality of life was examined using CAT and mMRC questionnaires. The lung function was assessed by spirometry. Two-year mortality was determined according to data extracted from the national death register.

Results: Two-year mortality rate was 11.8%. The investigated comorbidities – DM, MS, arterial hyper-tension (AH) and vitamin D status were no predictors of the two-year mortality. Mortality was increased in patients with mMRC ≥ 2 (17.2 vs. 1.9%, p = 0.005) and CAT score ≥ 10 (14.2 vs. 0%, p = 0.045). Severe exacerbation during the previous year was a risk factor for the registered two-year mortality (17.5% vs 5.6%, p = 0.021). The two-year mortality was increased in the group with FEV1 < 50%, compared to FEV1 > 50% (18.0 vs. 7.7%, p = 0.049). Cox regression analysis showed a 3.0% increase in the mortality rate for each 1% decrease in FEV1, 6.2% for each 1% decrease in PEF, 7.8% for one year of increasing age, 4% for 1% decrease in the FEV1/FVC ratio and 7.1% for each 1 point increase of CAT (all p-values < 0.05).

Conclusions: The two-year mortality of COPD patients following a severe exacerbation was relatively low. Chronological age, FEV1, history for severe exacerbation during the previous year, reduced quality of life, and low BMI were all associated with increased mortality. Disease Grade C, mMRC < 2, and CAT score < 10 were associated with a favourable prognosis.
Myocardial Viability – An Important Decision Making Factor in the Treatment Protocol for Patients with Ischemic Heart Disease
Authors: Grigorov V. , Grigorov M. , Grigorov E. , Nocheva H.
Published: July 2022

Ischemic heart disease (IHD) affects > 110 million individuals worldwide and represents an important contributor to the rise in the prevalence of heart failure and the associated mortality and morbidity. Despite modern therapies, up to one-third of patients with acute myocardial infarction would develop heart failure. IHD is a pathologic condition of the myocardium resulting from the imbalance in a given moment between its oxygen demands and the actual perfusion. Acute and chronic forms of the disease may potentially lead to extensive and permanent damage of the cardiac muscle. From a clinical point of view, determination of the still viable extent of myocardium is crucial for the therapeutic protocol – since ischemia is the underlying cause, then revascularization should provide for a better prognosis. Different methods for evaluation of myocardial viability have been described – each one presenting some advantages over the others, being, in the same time, inferior in some respects. The review offers a relatively comprehensive overview of methods available for determining myocardial viability.

Authors: Şeker Burçin Şenol , Özkaynak Merve
Published: July 2022

Masonry churches, which are one of the cultural heritages, show the historical background, cultural and religious characteristics of the cities and material properties. Churches in the earthquake zone, which are different from each other in terms of typology and have a special importance, are at risk. The aim of this study is to examine the earthquake behavior of a church sample in Turkey and to provide a guide for structures with similar typology. The building was modeled and subjected to dynamic loads using macro modeling technique. Free vibration mode shapes were determined by modal analysis, and it was determined that these modes were mainly in the form of translation of the upper part of the structure. In the time history analysis, the stress and deformation values were determined. It has been observed that the stresses take high values at the supports and top of the main columns and in the arches connecting these columns to the side walls. It was concluded that the deformations reached their maximum values at the apex of the triangular gable walls in the upper part of the building. The results obtained are consistent with the damage the church received in past earthquakes.
Influence of Biomass Ash on the Performance and Durability of Mortar
Authors: Ramdane Rihab , Kherraf Leila , Abdelouahed Assia , Belachia Mouloud
Published: July 2022

This work revolves around the study of the partial substitution of cement by biomass ash (residue generated during incineration of wood waste) in mortar. The introduction of wood ash in the cement formulation allows solving some problems related to the lack of construction materials and protecting the environment. To carry out this work we have introduced wood ash as an addition which partially substitutes cement at three different replacement percentages (5%, 10% and 15%). We carried out tests on mortar in the fresh state (consistency, density and occluded air); evaluated its performance in the hardened state (compressive and flexural tensile strength), dimensional stability and its durability (water absorption by immersion and by capillarity as well as resistance to chlorides and acidic environments followed by XRD). Results obtained will be compared with the results of control samples with 0% substitution rate.

The results of this valorisation show that the incorporation of 5% of ash fillers in the cement improves mechanical resistance as well as certain durability parameters.

Over the course of the last decades, closed-loop supply chains (CLSC) and reverse logistics issues have attracted increasing attention owing to strict environmental laws, social responsibilities, economic interests, and customer awareness. Hence, the issue of closed-loop supply chain and reverse logistics has emerged as a field of research in the new era. This issue has received much attention because it allows recyclable products to return to their original cycle. Therefore, this study primarily intends to present a mathematical model for designing a supply chain network for recycled products. The multi-stage and multi-period objective function of the closed-loop supply chain is presented to meet that aim. In this chain, dismantling, recycling, and disposal centers are considered. The objective function is to reduce the total cost of the closed-loop supply chain. The results of optimizing the mathematical model demonstrate that this model has the necessary efficiency for use in recycled products.
Finite Dimensional Real Normed Spaces are Proper Metric Spaces
Authors: Nakasho Kazuhisa , Okazaki Hiroyuki , Shidama Yasunari
Published: July 2022

In this article, we formalize in Mizar [1], [2] the topological properties of finite-dimensional real normed spaces. In the first section, we formalize the Bolzano-Weierstrass theorem, which states that a bounded sequence of points in an n-dimensional Euclidean space has a certain subsequence that converges to a point. As a corollary, it is also shown the equivalence between a subset of an n-dimensional Euclidean space being compact and being closed and bounded.

In the next section, we formalize the definitions of L1-norm (Manhattan Norm) and maximum norm and show their topological equivalence in n-dimensional Euclidean spaces and finite-dimensional real linear spaces. In the last section, we formalize the linear isometries and their topological properties. Namely, it is shown that a linear isometry between real normed spaces preserves properties such as continuity, the convergence of a sequence, openness, closeness, and compactness of subsets. Finally, it is shown that finite-dimensional real normed spaces are proper metric spaces. We referred to [5], [9], and [7] in the formalization.

In this article we further develop field theory [6], [7], [12] in Mizar [1], [2], [3]: we deal with quadratic polynomials and quadratic extensions [5], [4]. First we introduce quadratic polynomials, their discriminants and prove the midnight formula. Then we show that - in case the discriminant of p being non square - adjoining a root of p’s discriminant results in a splitting field of p. Finally we prove that these are the only field extensions of degree 2, e.g. that an extension E of F is quadratic if and only if there is a non square Element a ∈ F such that E and (

F

F\sqrt a

) are isomorphic over F.

Acidophytic alpine mat-grass swards are rare in the alpine belt of the predominantly calcareous Southeastern Alps of Slovenia, mostly occurring where limestone is admixed with marlstone or chert. Those for which we were able to make phytosociological relevés can be classified mainly into two syntaxa: Carici curvulae-Nardetum strictae vaccinietosum gaultherioidis and Sieversio-Nardetum strictae vaccinietosum. At slightly lower elevations, in the forest zone of the subalpine plateau Pokljuka, we found similar swards occupying small areas in frost hollows with luvisol on limestone. They include character species of various subalpine-alpine sward and snow bed communities and are classified into the syntaxon Homogyno alpinae-Nardetum scorzoneroidetosum croceae.
Climate Strikes and Curricula: Insights from Norway
Authors: Tomren Tom Sverre
Published: July 2022

In this article, the author analyzes environmental pedagogy in the Norwegian curricula for environmental and sustainability education from 1997 to 2020. The author investigates how climate-striking youth evaluate the outgoing curricula through a survey in which 88 respondents participated. The survey reveals that young climate activists demand a more action-oriented education that emphasizes political change. The author discusses the findings against the background of radical eco-pedagogy and the works of Richard Kahn, Chet Bower, and David Orr and concludes that the youth striking against climate change is practicing the curriculum they are asking for and that schools should welcome the strikes.

A geography of creative networks: The case of a small European economy
Authors: Baláž Vladimír , Jeck Tomáš , Balog Miroslav
Published: July 2022

This research project analyses the effects of networking by creative and conventional enterprises at regional and inter-industry levels. It relies on a unique dataset provided by the Slovak Creative Voucher Scheme and has some novel elements. We used direct evidence of industry locations from projects developed by creative industries rather than proxies. Network analysis was applied to establish major patterns in regional and inter-industry cooperation by creative and conventional firms. Regression models were used to analyse the network structure. The findings from quantitative analyses were complemented with evidence from qualitative methods. The network included a wide variety of cooperating partners. A sample of creative firms supported by the Creative Voucher Scheme cooperated with partners from no less than 60 industries. Spatial proximity was a key condition for cooperation, enabling face-to-face contacts and the development of a trusting relationship between creative firms and their clients.
Resource efficiency and decarbonisation of economies in the European Union
Authors: Clodniţchi Roxana , Tudorache Octavia
Published: July 2022

People have always been interested in improving their quality of life. But how is this possible when the population is constantly growing, and the planet’s resources are dwindling? The efficient use of resources is not only believed to increase the general quality of life but also to contribute to the creation of a cleaner environment. But what is the relation between resource efficiency and a cleaner environment? The European Commission and the United Nations have been dealing with this key issue for many years now and the EU has forced member countries to meet certain targets. This paper presents some of the UN and EU’s policies with regard to climate change and resource efficiency and offers an independent evaluation of the achievements of Member States. We assumed that the implementation of the objectives of the EU climate and energy package improves the resource productivity and reduces its negative impact on the environment, relation analysed with the help of a linear regression model. Further, we have performed a critical study on the performance of EU-member states in meeting their GHG-emission targets correlated with the resource intensity of their economies, modelled using Microsoft Excel. Resource efficiency and the low-carbon economy have emerged as central themes in global discussions on the transition to a sustainable economy, and this paper sheds new light onto the connection between the two subjects.
The status of the European Stonechat (Saxicola rubicola) in Hungary: a review

In 2021, the European Stonechat (Saxicola rubicola) became the ‘Bird of The Year’ in Hungary, which makes it very timely to summarise our knowledge about the status of the species in the country and to emphasise conservation priorities.

In Hungary, the species is a common, widespread breeder of dry roadside grass strips, abandoned ploughlands, bushy slopes and vineyards. It is most likely in the arid habitats between the Danube and Tisza and east of the Tisza. The largest populations also breed in these regions. The Hungarian population was estimated at 195,000–210,000 pairs between 2014 and 2018. The breeding population halved between 1999 and 2018, though it was stable until 2004. The breeding period begins from late March to early April and lasts until the end of July. First males arrive in February, and spring migration peaks in early March. Autumn migration peaks in late September. Few may overwinter. The number of birds ringed in Hungary since 1951 is 13,484, of which 1,401 were juvenile. Three birds ringed in Hungary were found abroad (Italy 2, Greece 1), and two specimens marked abroad (Croatia, Italy) were found in Hungary. The oldest bird was recaptured 1679 days after its ringing day in Hungary. The average body mass of juveniles increased significantly for both sexes by an average of 0.9 grams over 22 years. In the case of all age and sex groups, the average body mass increased during the autumn season. The average wing length of adults also increased during the autumn. The arrival time of either sex during spring migration did not change significantly between 1999 and 2020. In the case of all age and sex groups, the arrival time shifted later in autumn migration. The European Stonechat belongs to the red list category Near Threatened in Hungary.
Higher level taxonomy affects body mass and femur length as predictors for egg size in birds
Authors: Deeming D. Charles
Published: July 2022

Interpretation of fossil material using comparative anatomy often relies on relationships predicted from data collected from extant species. Some years ago, it was suggested that femur length of birds could be predicted from egg mass but this relationship was counter-intuitive because egg mass is usually related to a measure of body size. The original analysis was also not phylogenetically controlled. This study used the same data to determine phylogenetically controlled relationships for body mass versus egg mass, and egg mass versus femur length. Further analysis showed that order was important in the prediction of egg mass from either body mass or femur length. For some orders, the single regression estimate through all data significantly over-, or under-estimated egg mass. This problem was more pronounced for femur length compared with body mass. Extrapolation of the relationship between femur length and egg mass for large extinct birds seemed to be provide useful data for the Gastornithidae but under-estimated egg mass for other large bird species of a variety of families. Use of equations derived from extant birds to gain insight into the reproductive biology of extinct species needs to be undertaken with great care.
Observations on parental care of the Eurasian Spoonbill (Platalea leucorodia) during the post-fledging dispersal
Authors: Pigniczki Csaba
Published: July 2022

The number of available publications on the post-fledging parental care of wading birds (herons, ibises, spoonbills, and storks) and many other bird species is limited. In this study, I summarised the available knowledge collated from the observations of the Eurasian Spoonbills (Platalea leucorodia) in Hungary. A part of the available data is based on observations of colour-ringed individuals. The latest feeding event of a young by its parent was observed at Lake Csaj on 5 October 2020. The youngsters were being fed by their parents for 43 days (observed maximum) during the post-fledging dispersal. However, I estimated that this behaviour could even last for as long as 53 days. The parents lead (care for) their yearlings for 51 days (observed maximum), again I estimated that it could potentially last for a longer period of 63 days. The estimated length of parental care and feeding period could be longer or a little bit shorter during the post-fledging dispersal because it was not possible to follow the life of the families exactly. During parental care (feeding and leading of chicks), the majority of the colour-ringed Spoonbills were observed 2–26 km to the natal colonies of yearlings and the breeding colonies of the adults. However, on some occasions, they were 111–145 km far from those colonies. During the post-fledging dispersal, Spoonbills care for their chicks for a longer time than the European breeding heron species. A possible reason could be that the bills of young Spoonbills are not appropriate for fishing effectively at the beginning of fledging because of their shorter length and their less efficient hydrodynamic effect during lateral sweeping. Another reason could be that Spoonbills are tactile foragers and need more time to learn fishing. Based on data of a juvenile followed by a GPS device, learning the migration route and stop-over sites from parents or experienced adults could be important for Spoonbills, otherwise, young migrating alone with no accomplished individuals may not find the optimal routes and the proper stop-over areas. In the case of Spoonbills, we still do not know exactly the features of parental care during the post-fledging dispersal and have even less data on it during the migration. Thus, I request potential observers along the Adriatic Flyway to record the observations of parent-offspring interactions (feeding by parents, begging) particularly the Hungarian colour-ringed adults and/or young individuals and send data to the author’s e-mail address.
