Development of COVID-19 Case in District and City of Jambi Province with Exponential Smoothing Methode
Get PDFJambi Province is one of the province in western Indonesia, which was affected by COVID-19 in March and until mid-September the number confirmed positive reached 345 people. Until now COVID-19 has become a pandemic.Based on this data, it is necessary to predict the number of COVID-19 in Jambi Province, including every district in Jambi city. Double exponential smoothing: The Holt two-parameter method determines the value of the trend with a tang parameter different from the parameter used in the original series. The principle of forecasting using multiple exponential smoothing: The Holt two-parameter method uses two smoothing constants with values between 0 and 1. Based on the results of forecasting using the double exponential smoothing by Holt method, it can be seen that the number of confirmed cases of Covid-19 in each region in Jambi Province continues to increase. This case is estimated to increase to 352 people in mid-October
PENERAPAN METODE GEOGRAPHICALLY WEIGHTED REGRESSION PADA TINGKAT PENCEMARAN AIR BERDASARKAN TOTAL COLIFORM DI PROVINSI JAMBI
No full textThe purpose of this study is to obtain a local estimation model formed by considering spatial factors on the level of water pollution based on total coliforms in Jambi Province and can determine the most dominant factors affecting the total coliform water of PDAM Districts / Municipalities in Jambi Province using Geographically Weighted Regression (GWR) analysis. The type of data used in this study is primary data in quantitative form. This primary data was obtained by taking PDAM water samples directly in 9 regencies/cities in Jambi Province. The results of GWR analysis show that the dominant factors affecting the total coliform of PDAM water in each district/city in Jambi Province vary with different estimated parameters. The best model formed is a model with the GWR method, the adaptive bisquare weighting function which is shown from the value of the model's goodness criteria, namely the smallest AIC value and the largest coefficient of determinatio

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
NPWP ENCRYPTION USES A COMBINATION OF ONE TIME PAD ALGORITHM AND EXCLUSIVE-OR OPERATION
Get PDFNomor Pokok Wajib Pajak (NPWP) is the 20 distinct code characteristics that are confidential only to the taxpayer when it comes to making tax transactions. The many tax payers who use NPWP others in their business activities make NPWP a very important aspect of maintaining confidentiality and the authenticity of their data. Therefore, solutions are needed that can be used to make the necessary information secure. Cryptography involves the secret science of code writing using certain mathematical models.The study discusses NPWP encryption using a combination algorithm One Time Pad (OTP) and an operation Exclusive-OR (XOR). The encryption process involves generating random numbers for an OTP algorithm, after which it is followed by an XOR operation. The key on XOR encryption is generated from an algorithm generating random numbers Blum Blum Shub. Encryption keys generated as much as the number of plaquic characters. The encryption keys used by each character would vary and not occur again. Therefore, ciphertext results from an encrypted process using an OTP algorithm and an XOR operation more complicated and more difficult to decipher by crypts
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Get PDFWe 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
