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
TEACHING SPEAKING BY ROLE-PLAY ACTIVITY
Full text linkThe students often find some problems in practising English speaking. The problem frequently found is that their native language causes them difficult to use the foreign language. Other reason is because of motivation lack to practice the second language in daily conversation. They are also too shy and afraid to take part in the conversation. Many factors can cause the problem of the students’ speaking skills namely the students’ interest, the material, and the media among others including the technique in teaching English. There are many ways that can be done by the students to develop their ability in speaking English. The appropriate technique used by the English teacher also supports their interested in practising their speaking. One of the techniques that can be applied is role play.</p
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
AMERICAN DREAM IN LANGSTON HUGHES'S SELECTED POEMS: A SOCIOLOGY OF LITERATURE ANALYSIS
Full text linkABSTRAK
Penelitian ini bertujuan untuk menganalisis lima puisi karya Langston Hughes dengan pendekatan Sosiologi Sastra. Penulis membahas bagaimana kondisi sosial masyarakat di Amerika pada abad kedua puluh dan mimpi masyarakat Afrika-Amerika dalam puisi-puisi tersebut. Penelitian ini didukung oleh unsur-unsur diluar teks sehingga membangun totalitas makna; antara lain sejarah, sosiologi, politik, dan ekonomi. Penulis menemukan bahwa puisi-puisi ini menunjukkan bahwa masyarakat Afrika-Amerika bermimpi agar bisa setara, bebas, bahagia, kaya dan sukses. Melalui penelitian ini, penulis berkesimpulan bahwa masyarakat Afrika-Amerika telah terdiskriminasi sebelum dan sesudah puisi-puisi ini diterbitkan. Diskriminasi inilah yang membuat mereka menjadi kesulitan untuk menggapai mimpi-mimpi di negerinya sendiri. Meskipun begitu, mereka tetap tegar dan percaya bahwa satu hari nanti mimpi mereka akan menjadi kenyataan.

ANALISIS KERUSAKAN PANTAI
KECAMATAN PONDOK KELAPA KABUPATEN BENGKULU TENGAH
DAN PENENTUAN KONSEP PENANGANANNYA
Kecamatan Pondok Kelapa, Kabupaten Bengkulu Tengah terletak di
bagian barat Pulau Sumatra, yang berhadapan langsung dengan Samudra
Indonesia. Lokasi ini menyebabkan pantai di Kecamatan Pondok Kelapa banyak
menerima limpasan-limpasan gelombang, baik berupa hempasan gelombang laut,
fluktuasi muka air laut dan arus sepanjang pantai (longshore current). Hal ini
menyebabkan adanya perubahan garis pantai yang sifatnya merusak pantai berupa
abrasi, erosi, maupun sedimentasi. Proses kerusakan pantai di Kecamatan Pondok
Kelapa ini telah mempengaruhi kondisi perekonomian dan psikologis masyarakat
yang bertempat tinggal di sekitar lokasi kerusakan pantai.
Tujuan penelitian ini adalah untuk mengidentifikasi jenis kerusakan pantai
di Kecamatan Pondok Kelapa, menganalisis penyebab kerusakan pantai tersebut
dan menentukan konsep penanganannya. Metode penelitian yang digunakan
adalah deskriptif analitik melalui studi kasus. Penelitian dilakukan dengan
mendeskripsikan secara rinci kerusakan pantai di Kecamatan Pondok Kelapa
sehingga mendapatkan gambaran faktual dan penyebabnya dengan pengolahan
data tertentu.
Proses kerusakan pantai Kecamatan Pondok Kelapa terjadi akibat faktor
alam berupa kondisi hidro-oseanografi lokasi dan faktor antropogenik berupa
kegiatan masyarakat, baik sengaja ataupun tidak sengaja yang dapat menyebabkan
kerusakan pantai. Hal ini dapat diketahui dari hasil analisis data sekunder berupa
kecepatan arus sepanjang pantai yang berkisar antara 1,72 m/s hingga 2,38 m/s
0
dengan sudut gelombang datang lebih besar dari 5 . Volume total angkutan
3
transpor sedimen sepanjang pantai sebesar 425.550 m /tahun. Kegiatan manusia di
sekitar lokasi penelitian seperti alih fungsi lahan tanaman pelindung pantai di sisi
muara sungai menjadi perkebunan kelapa sawit juga memperparah kerusakan
pantai di Kecamatan Pondok Kelapa. Maka perlu dilakukan penanganan yang
tepat dan terbaik terhadap kerusakan pantai tersebut, baik secara alami melalui
endors manusia dengan suplai sedimen (sand nourishment) dan penanaman
kembali tanaman pelindung pantai, maupun secara buatan dengan bangunan
pelindung pantai tembok laut (sea wall), revetmen, dan jetty .
Dari hasil penelitian direkomendasikan bahwa kajian mengenai kerusakan
pantai, terutama di Kecamatan Pondok Kelapa perlu dikembangkan bukan
hanya dari aspek fisik, tetapi juga perlu diperluas ke dalam aspek biotik, sosial
dan institusi. Wujud keterpaduan antara pemerintah dengan stakesholder serta
keterlibatan masyarakat terhadap penanganan kerusakan pantai, terutama di
sekitar pantai yang mengalami kerusakan dapat mendukung keberhasilan dalam
menangani kerusakan pantai di Kecamatan Pondok Kelapa. Harapan ini mengacu
dan bersesuaian dengan implementasi pengelolaan wilayah pantai terpadu.

No full textChloramphenicol is a broad-spectrum antibiotic that is active against gram
positive and gram negative bacteria that are currently used by people to treat these
types of infections due to bacteria by inhibiting protein synthesis required for the
formation of the bacterial cells widely. The purpose of this test is to determine
whether Chloramphenicol capsules produced by PT. Kimia Farma (Persero) Tbk.
Plant Medan has been fulfilled dissolution test of the requirements as determined
by the Pharmacopoeia Edition V. Chloramphenicol capsules must go through a
series of tests to determine the quality of the capsule. One of the test is the
dissolution test. Where dissolution is a process of transfer of drug molecules from
the solid become the solution medium. The sample consisted of six capsules taken
from a single batch. Dissolution test was performed by using a type of basketball
(basket method) and the assay solute conducted by using UV-Visible
spectrophotometry. So from the test results shown that the levels of solute from all
