Spatiotemporal distribution of Eurasian Spoonbills (Platalea leucorodia) outside the Carpathian Basin – the results of the Hungarian colour-ringing project based on twenty years (2003–2023)
No full textThe Eurasian Spoonbill (Platalea leucorodia) is a migratory waterbird. We used the confirmed
observations of colour-ringed individuals (2,735 specimens) of the Hungarian population collected outside the
Carpathian Basin between May 2003 and February 2023. 546 Spoonbills occurred in 28 countries. They used
mainly the Central Mediterranean Flyway, however, some individuals were seen along the East Atlantic Flyway
or the East Mediterranean Flyway. Three individuals were observed north of the Alps, too. A small proportion
of Spoonbills crossed the Sahara and they occurred in the Sahel zone, between Sudan in the east and Senegal
and Mauritania in the west. A few individuals were observed on Saharan wetlands in Algeria during winter. The
most important destination for the Hungarian (Pannonian) population during the migration is Tunisia, where
many of them spend the winter, primarily in the tidal area of the Gulf of Gabes. The first adults reached North
Africa (Tunisia) on 28 July during their southward migration, while the last ones stayed there until 23 April.
The first observation of juveniles in North Africa (Tunisia) happened on 31 August. Immature, 2- and 3-cy-
old birds spend the summer in unknown numbers in Tunisia. The majority of Pannonian Spoonbills migrate
through the Balkans and Italy and some stay there to winter, mainly in Italy. Some of the immatures spent the
summer in Italy. In southern Europe, the peak of the spring migration was in March, and the peak of the autumn
migration was in September. There was also a difference in the migration of different age groups: in Southern
Europe, the migration peak of adult birds falls between March and April, while most of the immatures were
observed in May and June during northward migration. The peak of the southward migration in all age groups
was observed in September. In the southern part of Europe, there may still be adults migrating north on 13
May, while other adults may already migrate southward on 15 May. The earliest juvenile migrating south was
documented on 30 June in Italy
Contribution au suivi de la population nicheuse du faucon crecerellette (Falco naumanni) à l'Aqueduc de Zaghouan (Tunisie)
No full textLe faucon crécerellette (Falco naumanni) est une espèce globalement menacée. Nous avons étudié la dynamique de la population de Zaghouan (Tunisie). Nos résultats suggèrent que le nombre des couples nicheuses à l'Aqueduc diminue significativement d'une année à une autre. Ce résultat serait du à la destruction ou la modification des habitats du fait des travaux de restauration de l'Aqueduc. La protection et la restauration des habitats et des sites de reproduction en particulier ainsi que l'aménagement des sites de nidification constituent les principales mesures proposés pour la conservation de l'espèce en Tunisie.The Lesser Kestrel (Falco naumanni) is a globally threatened species.We studied the population dynamics of nesting Lesser Kestrels at the aqueduct of Zaghouan (Tunisia). Our results suggest that the number of nesting pairs at this site has decreased significantly from year to year. This is primarily due to destruction or modification of nest sites during restoration of the aqueduct. The protection and the restoration of their habitat, especially of breeding sites, as well as the installation of additional nesting sites, constitute the principal conservation measures proposed for this species in Tunisia.

The ‘Eurasian' Spoonbill (Platalea leucorodia) in Africa
No full textThe ‘Eurasian' Spoonbill (Platalea leucorodia) nests in discrete areas across the western Palaearctic and is considered to be threatened. Western breeding populations winter along the Atlantic seaboard of Mauritania and Senegal, where they mingle with the Mauritanian subspecies P. l. balsaci. Their movements have been studied through colour ringing, which has shown that they spend their early years in Africa. Observations of Dutch breeding birds in the Mediterranean are scarce. The central European breeding population nests mainly in the Danube Basin. Recoveries of metal rings show that, while some winter in the Inner Niger Delta, most stay in the tidal Mediterranean areas of southern Tunisia and Libya, thus avoiding a long trans-Saharan journey. New colour-marking programmes in Italian and Greek breeding colonies have provided more information, but as yet there is no proof that young birds summer in the area. Some central European Spoonbills move through the Nile Delta and along the Nile to winter in southern Egypt and Sudan. Breeding Spoonbills of eastern Europe and western Asia also winter in southern Egypt and Sudan, while some winter as far east as Oman; as yet there are few ringing recoveries, but a colour-ringing programme in the Danube Delta begun in 2003 has already yielded recoveries in Spain and Oman. There is another African-breeding subspecies P. l. archeri in the Red Sea. We need to establish the importance of African wetlands for Spoonbills, concentrating on colour-ringed individuals, surveys in Libya, Egypt and Sudan, a search for summering immatures, and an investigation of why birds from the same breeding colonies take such different migration routes. La spatule blanche Platalea leucorodia (dite «eurasiatique» en langue anglaise!), espèce considérée comme étant menacée d'extinction, niche dans des zones discontinues du Paléarctique occidental. Les populations occidentales hivernent le long des côtes atlantiques de la Mauritanie et du Sénégal, où elles retrouvent la sous-espèce mauritanienne P. l. balsaci. Leurs migrations ont été étudiées grâce à l'utilisation de bagues en couleur, qui ont montré que les jeunes spatules passent leurs premières années en Afrique; les observations en Méditerranée d'oiseaux d'origine hollandaise sont rares. La population nicheuse de l'Europe centrale se reproduit surtout dans le bassin du Danube. Des reprises de bagues métalliques montrent que, si certains oiseaux hivernent dans le Delta Intérieur du Niger, la plupart restent en hiver dans les zones côtières, soumises à la marée, de la Tunisie méridionale et de la Libye, et évitent ainsi la longue traversée du Sahara. De nouveaux programmes de baguage en Italie et en Grèce, à l'usage de bagues de couleur, ont fourni des informations supplémentaires, mais jusqu'à présent la preuve de séjours estivaux dans ces zones par les immatures fait défaut. Certaines spatules venant d'Europe centrale traversent le delta du Nil pour hiverner dans le sud de l'Egypte et au Soudan. Les spatules nicheuses de l'Europe orientale et de l'ouest de l'Asie hivernent également dans le sud de l'Egypte et au Soudan, et certains vont jusqu'en Oman; jusqu'à présent, les reprises de baguage sont rares, mais un programme de baguage, entamé en 2003 dans le delta du Danube, a donné lieu à des reprises en Espagne et en Oman. Une deuxième sous-espèce africaine P. l. archeri, niche dans la Mer Rouge. Nous devons confirmer l'importance des zones humides africaines pour la spatule blanche, en utilisant des bagues de couleur, en effectuant des prospections en Libye, en Egypte et au Soudan, en recherchant les immatures estivants et en approfondissant la question de pourquoi les individus d'une même colonie suivent des chemins de migration tellement variables.

Does investment deposit return in Islamic banks reflect PLS principle?
No full textAbstractThe main purpose of this paper is to examine the compliance of investment deposit return with profit and loss sharing principle. This compliance is analyzed through the impact of bank's risk, governance mechanisms and competition environment on investment deposit return. We use a pooled regression model applied to a panel of sixty Islamic banks during the period 2004–2012. The estimation indicates that the management of investment deposit and PLS assets is characterized by a moral hazard behavior and excessive risk taking. The estimation reveals that capital ratio and interest rate affect positively investment deposit return. Small Islamic banks offer a better return of deposit compared to the large bank. We find no evidence of the impact of board of directors and Sharia board. Following these results, we suggest that investment accounts holders should be integrated in the bank governance system. Besides, the Islamic banks are incited to develop a new generation of investment deposits

It is based on a meaningful segmentation procedure that can provide proper distributions for matching via the Earth mover's distance as a similarity metric. The segmentation procedure is based on a hierarchical watershed-driven algorithm that extracts meaningful regions automatically. In this framework, the proposed robust feature extraction and the many-to-many region matching along with the novel region weighting for enhancing feature discrimination play a major role. Experimental results demonstrate the performance of the proposed strategy

세계태권도연맹의 거버너너스 :
No full text학위논문 (석사)-- 서울대학교 대학원 : 체육교육과, 2016. 8. 김기한.To keep the value of the Olympic Games the IOC has removed several sports with different reasons and it has been calling other International Federation to implement good governance principals and to be in line with Olympic values. So far WTF has succeeded in safeguarding its place as Olympic Sport, but its still in risk of being in Olympic. This study therefore seeks to evaluate how good the governance system of WTF was before and after 2004. To illustrate the impact of both governance system on Taekwondo as an Olympic Sport. We also intend to examine the similarities and differences in the governance system between the two governing by comparing each pair of dimensions in the Chapellet seven Basic Indicator for Better Governance in International sport.
In order to evaluate how good the governance system of WTF was before and after 2004, to illustrate the impact of both governance system on Taekwondo as an Olympic Sport and to examine the similarities and differences in the governance system between the two governing body. The author will investigate the achievements of both governing body during the last 42 years. Questionnaire based on Basic Indicators for Better Governance in International Sports BIBGIS and interview will be conducted to compare the two governance system in WTF and analyze their impact on Taekwondo as an Olympic Sport.올림픽게임이 가지고 있는 가치 보존을 위해 IOC는 각기 다른 이유들로 몇몇 스포츠 종목을 제거했으며 이것은 국제연합 IF가 올림픽가치실현 함께 좋은 거버넌스를 실현할 수 있도록 도와주었다. 지금까지 세계태권도연맹은 올림픽 스포츠의 일환으로 성공적으로 산업보호를 해왔지만 여전히 올림픽의 한 종목으로 인정받기까지 어려움이 있다. 그러므로 본 연구는 2004년 전후로 태권도연맹협회의 좋은 거버넌스체계가 어떻게 평가하고 있는지 연구하기 위한 것에 목적이 있다. 올림픽스포츠에 있어 정부와 태권도연합의 영향력을 설명하기 위해 국제스포츠에 있어 더 나은 정부의 구조 안에서 7가지 요소로 측정하여 비교하여 두 정부 시스템 사이의 유사성과 차이점에 대해 실험하려 했다. 저자는 지난 42년 동안 정부조직의 성과를 종합한 것이다., 설문지는 BIBGIS 국제스포츠조직 좋은 거버넌스의 기본요소에 바탕을 두고 진행되었으며 인터뷰는 국제태권도조직의 두 거버넌스 시스템을 비교하고 올림픽스포츠에 있어 태권도의 영향력을 분석하는 것으로 수행될 것이다.Chapter I.
