Abstract In the article is analyzed own field data of the authors and scientific publications on the wintering of Anserinae in the Azov-Black Sea region of Ukraine in 1900–2017, but the main data was obtained in frame of international mid-winter counts (IWC) in 2005–2017. It was found that 9 species of Anserinae occur in this region during the different seasons of the year: Anser anser — nesting, wintering and migrating; Rufibrenta ruficollis, A. albifrons, A. erythropus, A. fabalis — migrating and wintering; Branta canadensis, Branta leucopsis, Branta bernicla, Chen caerulescens — vagrant or birds which flew away from captivity (zoo etc.). Eulabeia indica — is possible vagrant species. The most numerous wintering species is A. albifrons, common — Rufibrenta ruficollis, not numerous — Anser anser, the other species are not met annually and registered in a very small number. There was almost tenfold drop in number of wintering geese in the Azov-Black Sea region of Ukraine during the period of counts. The main reasons of such reducing of geese amount are the followwing: weather and climate conditions, changes in the forage acessibility, hunting and poaching pressure, poisoning as a result of deratization of agricultural lands, and from 2014 — the militarization of the Syvash area and stop of water supplying of Crimea through the North Crimean channell. It is likely that the factors mentioned above led to relocating of wintering areas of Anserinae, and resulted in decreasing of their amount in this region.

The Alaskan population of Emperor Geese ( Chen canagica) nests on the Yukon–Kuskokwim Delta in western Alaska. Numbers of Emperor Geese in Alaska declined from the 1960s to the mid-1980s and since then, their numbers have slowly increased. Low statistical power of microsatellite loci developed in other waterfowl species and used in previous studies of Emperor Geese are unable to confidently assign individual identity. Microsatellite loci for Emperor Goose were therefore developed using shotgun amplification and next-generation sequencing technology. Forty-one microsatellite loci were screened and 14 were found to be polymorphic in Emperor Geese. Only six markers – a combination of four novel loci and two loci developed in other waterfowl species – are needed to identify an individual from among the Alaskan Emperor Goose population. Genetic markers for identifying sex in Emperor Geese were also developed. The 14 novel variable loci and 15 monomorphic loci were screened for polymorphism in four other Arctic-nesting goose species, Black Brant ( Branta bernicla nigricans), Greater White-fronted ( Anser albifrons), Canada ( B. canadensis) and Cackling ( B. hutchinsii) Goose. Emperor Goose exhibited the smallest average number of alleles (3.3) and the lowest expected heterozygosity (0.467). Greater White-fronted Geese exhibited the highest average number of alleles (4.7) and Cackling Geese the highest expected heterozygosity (0.599). Six of the monomorphic loci were variable and able to be characterised in the other goose species assayed, a predicted outcome of reverse ascertainment bias. These findings fail to support the hypothesis of ascertainment bias due to selection of microsatellite markers.

Central Data

In data warehousing, the data from source systems are populated into a central data warehouse (DW) through extraction, transformation and loading (ETL). The standard ETL approach usually uses sequential jobs to process the data with dependencies, such as dimension and fact data. It is a non-trivial task to process the so-called early-/late-arriving data, which arrive out of order. This paper proposes a two-level data staging area method to optimize ETL. The proposed method is an all-in-one solution that supports processing different types of data from operational systems, including early-/late-arriving data, and fast-/slowly-changing data. The introduced additional staging area decouples loading process from data extraction and transformation, which improves ETL flexibility and minimizes intervention to the data warehouse. This paper evaluates the proposed method empirically, which shows that it is more efficient and less intrusive than the standard ETL method.

Jepaplok merupakan judul dari sebuah karya tari kelompok yang di dalamnya melibatkan sembilan penari perempuan. Kata Jepaplok yaitu berasal dari Njeplak (Manggap) dan Nyaplok (mencaplok). Karya tari ini berawal dari pertunjukan Jaranan di Tulungagung Jawa Timur. Barongan atau biasa disebut Caplokan/Jepaplok adalah penggambaran hewan mitologi berupa ular naga sebagai penguasa hutan yang jahat. Sosok yang dilihat dari segi visualnya menyeramkan dan ganas, serta dari sudut geraknya yang sangat ekspresif. Gerak-gerak dasar yang digunakan antara lain seperti leang-leong, ngaplak, ngepruk, sondongan, pattetan, dan sundangan. Karya tari Jepaplok terdiri dari 4 bagian adegan. Pada bagian introduksi dipertunjukkan sosok Barongan dan Jaranan yang berbeda ruang dan kemudian saling menyerang. Bagian 1 berfokus pada gerak Barongan tanpa menggunakan properti topeng. Pada bagian 2 persiapan penyerangan terhadap penari Jaranan, sehingga dalam bagian ini sudah menggunakan properti topeng. Bagian 3 lebih kepada esensi penggunakan topeng dan diolah dengan permainan ritme dan menggunakan komposisi berpasangan. Bagian 4 yaitu akhir dari pertunjukan karya tari Jepaplok yaitu perangan Barongan dan Jaranan. Tetapi pada bagian akhir ini tidak semata-mata saling berhadapan satu dengan yang lain melainkan hanya sebatas permainan per kelompok. ABSTRACT Jepaplok is the title of a workgroup in which dance involving nine female dancers. The word Jepaplok is derived from Njeplak (Mangap) and Nyaplok (annexed). This dance originated in the works of interest in dance salon when watching a show used Jaranan (dance horse) in Tulungagung, East Java. The point of view of the Director of the dance stopped when one of the characters enter the staging area performance Barongan. Suspenseful atmosphere emerges when section toward the battle between used Horse and Barongan. Barongan or commonly called Caplokan/Jepaplok is the depiction of mythological animals in the form of a dragon serpent as ruler of the evil forest. The figure is seen in terms of the Visual sinister and vicious, as well as from the point of highly expressive movements that inspired the stylist for him to dance in a group dance with paper based on motion and feel the music used Jaranan Sentherewe Tulungagung, East Java. The focus of the implementation work of the dance called Jepaplok is more to perangan and Barongan figures. Basic motion-motion that is used among other things such as leang-leong, ngaplak, ngepruk, sondongan, pattetan, and sundangan. In the work of this Jepaplok dance doesn't bring up the story and consists of four parts of the scene. On the introduction of a dance figure demonstrating Barongan and different spaces used Horse and then each other. Part one is more focused on motion the Barongan poured into members of the body of a dancer without using the mask property. In part two, namely more to preparation which showed Barongan attacks against dancers used Horse, so in this section are already using property mask. Part three more to the essence of the use of mask and mingled with the game rhythm and composition using paired. Part four, namely the ending of the show dance work Jepaplok, as in general the final part of the art used Horse namely perangan and Barongan used Horse. But in the end, it does not solely face each other with one another but rather only as a game between groups.
