No full textThe Geology of Kobatuwa Site, Residency of Ngada Central Flores, East Nusa Tenggara. Kobatuwa Site is a part of Soa Basin, which is located at the Piga village, Soa Sub-district, Ngada Regency, EastNusa TenggaraProvince. Geographically this site is situated at 8°41 'l 7,4" Southern Latitude and 121 °05' 16,4" Eastern Hemisphere. Morphologically, the Kobatuwa Site formed by weakly undulated hills with maximum elevation of about 325 m high above sea level. The main river and its tributaries show centripetal drainage pattern and they belong to periodic and episodic rivers. The rocks unit at the Kobatuwa site and its surroundings are: Tuff Unit (Early to Middle Pleistocene), Volcanic Breccia Unit (Early to Middle Pleistocene), Conglomerate Unit (Early to Middle Pleistocene), and Alluvial Deposits (Holocene). Normal fault is found in theKobatuwa Site and surroundings. The lithic and bone fragments of vertebrate fossil bones found at the Kobatuwa Site and its surroundings provide an information of the aspect and the characteristics of the cultural remains at this area. The relative dating of this site reveals 700,000 - 60,000 years BP, and the lithic artifacts from the Kobatuwa Site are classified as the massive tools

No full textAbstract. The Geology of the Paleolithic Site of the Eastern Part of Pacitan, Pacitan Regency, East Java Province. The Paleolithic Site of the Eastern Part of Pacitan is located at Km-10 to Km-18 east of the city of Pacitan to the direction of Trenggalek regency. It covers three main rivers, namely Kedunggamping (Padi) River, Ngrendeng-Tulakan River, and Lorog River. The site has lowland, weak wavy, strong wavy, and karst morphological units. It is situated at an elevation of O - 900 m above sea level. The three rivers that flow in this area are old and old-mature stadium ones, with observable trellis and rectangular desiccated patterns. They belong to periodic, consequent, and subsequent types. The rocks that compose the area are volcanic breccia, conglomerate, ingenous rock unit, sand stone, tuff, clay-stone, silt, limestone unit, and alluvial sediment, with ages that range from Oligocene up to Holocene. The geological structures that are found in this place include sincline fold and strike slip. The river terraces belong to the first, which still directly connected to the river surface. Disturbance on geological structure is one of the factors that influence the position and existence of the river terraces. Lithic tools made of chert, andesite, jasper, silicified-limestone, wood fossil, chalcedony, and limestone are found at this site. The raw materials of those tools (granule, pebbles, and boulders) are usually available along the rivers.Abstrak. Lokasi Situs Paleolitik Pacitan bagian Timur terletak di Km-10 hingga Km-18 sebelah timur Kota Pacitan ke arah Kabupaten Trenggalek. Situs Paleolitik ini meliputi wilayah Sungai Kedunggamping (Sungai Padi), Sungai Ngrendeng-Tulakan, dan Sungai Lorog. Bentang alam wilayah situs ini termasuk pada satuan morfologi dataran, satuan morfologi bergelombang lemah, satuan morfologi bergelombang kuat, dan satuan morfologi karst. Ketinggian situs berada pada O - 900 meter di atas permukaan air laut. Ketiga sungai itu termasuk pada sungai berstadia Tua (old river stadium) dan Dewasa-Tua (old-mature), dengan kenampakan pola pengeringan Trellis dan Rectangular. Selain itu, termasuk pada Sungai Periodis, Sungai Konsekuen, dan Sungai Subsekuen. Batuan penyusun wilayah situs adalah breksi vulkanik, konglomerat, satuan batuan beku, batu pasir, tufa, batu lempung, batu lanau, satuan batu gamping, dan endapan aluvial. Kisaran umurnya ialah dari Oligosen hingga Holosen. Struktur geologi yang melewati wilayah situs adalah Lipatan (fold) dari jenis sinklin, dan Patahan (fault) dari jenis sesar geser. Undak-undak sungai yang teramati termasuk pada undak sungai pertama yang masih berhubungan langsung dengan muka air sungai. Gangguan struktur geologi ikut mempengaruhi keletakan dan keberadaan undak-undak sungai itu sendiri. Alat-alat litik terdiri dari batuan chert, andesit, jasper, batugamping kersikan, fosil kayu, kalsedon, dan batugamping. Sumber bahan baku alat-alat litik tersebut umumnya berada di alur-alur sungai dalam bentuk kerikil, kerakal, dan boulder batuan
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
