Dinamika Pembentukan Kata Bahasa Indonesia
Full text linkBahasa Indonesia sebagai salah satu bahasa di dunia tidak mungkin mempertahankan kemurnian dan kemandiriannya. Bahkan, bahasa Indonesia tergolong bahasa yang tidak murni karena dari awal kelahirannya tidak ada bahasa Indonesia. Istilah Indonesia baru muncul belakangan. Tilikan terhadap dinamika pembentukan kata bahasa Indonesia bertolak dari dua sudut pandang. Pertama, sudut pandang internal, yaitu sudut pandang yang terfokus pada kaidah pembentukan kata yang ada dalam sistem bahasa Indonesia. Kedua, sudut pandang eksternal, yaitu sudut pandang yang menekankan pembentukan kata dari pengaruh bahasa lain, baik asing maupun lokal. Proses pembentukan kata secara internal yang lazim terjadi dalam bahasa Indonesia mencakup: afiksasi, reduplikasi, pemajemukan, pemendekan, dan derivasi balik. Dari beberapa pembentukan kata ini, tidak semua dianalisis tetapi hanya dikhususkan pada pembentukan kata yang dinamis (mengalami pasang surut). Hasil pengkajian membuktikan bahwa pembentukan kata dalam bahasa Indonesia dewasa ini, senantiasa mengalami dinamika. Kecenderungan dinamika mengarah pada munculnya afiks asing atau afiks bahasa serumpun, penanggalan afiks, munculnya leksikal baru, dan menyusutnya pemakaian kata yang sebelumnya sangat tinggi. Di sisi lain, ada kecenderungan bahwa morfem unik berubah menjadi morfem bebas. Kata Kunci: Proses pembentukan kat
MENYEMBUNYIKAN INFORMASI RAHASIA PADA CITRA BITMAP MENGGUNAKAN METODE BIT PLANE COMPLEXCITY SEGMENTATION
Full text linkWith the growing popularity of digital media, attention to the level of security becomes increasingly important. One important issue is the security level of the delivery of information. This can be done using encryption or steganography. Steganography is a method to insert a piece of confidential information in an object other media. Data hiding in steganography and cryptography are very different. If the cryptography, data that was encrypted (ciphertext) remain available, then the steganography, the ciphertext can be hidden so that third parties do not know it existed. In this project, the proposed media is the use of media such as image files JPG, GIF and BMP as input data a secret message carrier (carrier file). By using the method Compexcity Bit Plane Segmentation and DES encryption algorithms expect data confidentiality is guaranteed. The results of this project is to prove a technique of hiding secret messages in the media image. After going through the process and embeding data extraction process again from the stego file, confidential information may be disclosed again without damage or loss ofinformation
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
