<p>Though neotectonic activity is believed to be the major factor in the evolution of the topography of the Ejina Basin in Central Asia, detailed documentation and analysis of climatic landscape features and their environmental implications are lacking. The present study is a site-specific documentation of landforms developed in the wide part of the Ejina Basin, with the aim to identify the climatic landforms based on the method of climatic geomorphology and to evaluate its landscape evolution and response to palaeoclimate changes. The morphodynamics of older landscapes are recognized by making comparison with the present climate and its corresponding landscapes. Clear evidences testifying the basin-scale shifting and transformation of different morphoclimatic zones in the basin are observed, which prove that the main geomorphic unit is changed from an alluvial-lacustrine plain to a desert plain. The coexistence of diverse landscapes and the consequent geomorphodiversity in the basin should be a compound result of surficial processes other than glaciations. The climate and hydrological conditions of the basin during the last glaciation and during the Early Holocene were much better than at present, possibly having an average annual precipitation ranged between 60~350 mm on <del cite="mailto:unknown" datetime="2015-11-27T09:00"> </del>the basin during ca. 39-23 ka BP but great fluctuations during Holocene. The periods of lower aridity during the late Pleistocene in the bain could be induced by an increase of the westerlies and a weakening of the Asian winter monsoon on the arid areas of the central Asia.</p>

Tingkat pencapaian minat nasabah untuk memiliki kartu kredit BCA dipengaruhi oleh delapan kelompok variabel yang dikenal sebagai 8P yaitu Product, Price, Place, Promotion, Process, Physical evidence, People dan Produktivity and quality. Penelitian dilakukan di PT.Bank Central Asia, Jalan Mangga Besar Raya No. 128 Jakarta Pusat. Tujuan dari penelitian adalah untuk mengetahui bagaimana pengaruh faktor-faktor minat nasabah memiliki kartu kredit BCA. Penelitian ini menggunakan 2 metoda yaitu metoda deskriptif yaitu mengembangkan produk dan jasa yang sudah ada dan analisa kuantitatif dibagi menjadi dua analisa yang pertama analisa uji validitas dan analisa uji reabilitas. Data yang dianalisa yaitu analisis faktorfaktor yang menjadi daya tarik konsumen untuk memiliki kartu kredit BCA dapat dihitung dan diteliti langsung, data dianalisis dengan menggunakan SPSS versi 16.0. Responden telah mengisi 33 pertanyaan yang disebut dengan variabel dengan nilai skor dan dibagi berdasarkan kelompok sebagai faktornya. Hasil analisis dapat disimpulkan daya tarik konsumen untuk memiliki kartu kredit BCA ada 7 faktor utama. Faktor pertama Produk dengan nilai varians (11,74), faktor ke dua adalah Harga dengan nilai varians (10,73%), faktor ke tiga adalah Distribusi dengan nilai varians (8%), faktor ke empat adalah Promosi dengan nilai varians (7,77%), faktor ke lima adalah Proses dengan nilai varians (6,75%), faktor ke enam adalah Fisik dengan nilai varians (6,28%) dan faktor ke tujuh adalah Kualitas dengan nilai varians (5,76%). Faktor produk merupakan faktor yang paling mempengaruhi konsumen untuk memiliki kartu kredit BCA. Faktor ini dapat menerangkan keragaman data (varians) sebesar 11,74%. Dari beberapa analisis yang diperoleh bahwa faktor produk sangat berpengaruhi positif terhadap keputusan konsumen dalam memiliki kartu kredit BCA karena konsumen menginginkan produk yang baik agar dapat mempermudah transaksi dimana saja dan kapan saja.

The Elachistidae material collected during the joint Soviet-Finnish entomological expeditions to the Altai mountains, Baikal region and Tianshan mountains of the previous USSR is listed. Previous literature dealing with the Elachistidae in Central Asia is reviewed. A total of 40 species are dealt with, including descriptions of five new species: Stephensia jalmarella sp. n. (Altai), Elachista baikalica sp. n. (Baikal), E. talgarella sp. n. (southern Kazakhstan), E. esmeralda sp. n. (southern Kazakhstan) and E. filicornella sp. n. (southern Kazakhstan). The previously unknown females of E. bimaculata Parenti, 1981 and Biselachista zonulae Sruoga, 1992 are described.

Regions play an important part in scholarly discussions on Hellenistic Central Asia. Most commonly the concept of regions is determined by historically testified administrative entities. They also form the basis for many art-historical and archaeological considerations which seek to define specific regional characteristics. At the same time, such qualities are often used to define regional boundaries or elucidate political relationships. Taking the perspective of ceramic evidence, we highlight the complexities of interpreting pottery assemblages with regard to regional identities and inter-regional variations. Examining the different properties of ceramics, including their form, surface appearance and decoration, we demonstrate how changeable the notion of ‘region’ can be in this context. Distinct criteria and even minor chronological variations lead to the description of different regions, showing that we should use such definitions with care.

In 1972, a brief article titled “Khandud, Village de la Vallée du Wakhan” appeared in Afghanistan 25. The subsequent decades of conflict precluded any follow-up research in Wakhan. The current article, based on field work from 2004 to 2016, examines the present condition of the sites described in 1972, offers a revised analysis of their significance, and introduces newly discovered rock art that connects Wakhan with the Saka culture of Central Asia and illustrates indigenous traditions of the Pamir-Hindukush ethnolinguistic region.
