Pemodelan Ekonometrika Spasial Panel Dinamis Dengan Pendugaan Parameter Spatially Corrected Blundell-Bond Generalized Method Of Moment (Scbb-Gmm) Untuk Prediksi Nilai Produk Domestik Regional Bruto Kabupaten/Kota Di Provinsi Nusa Tenggara Timur
Full text linkProvinsi Nusa Tenggara Timur (NTT) merupakan daerah yang memiliki pembangunan ekonomi tertinggal, hal ini dilihat berdasarkan nilai PDRB tiap kabupaten/kota yang berada pada kelompok terendah dibandingkan kabupaten/kota lainnya di Indonesia. Ketertinggalan tersebut menjadi agenda pemerintah untuk mengelola dan membuat kebijakan di sektor ekonomi. Sebagai dasar pengambilan kebijakan perekonomian di tiap kabupaten/kota di Provinsi NTT diperlukan pengamatan secara berkala sehingga membutuhkan gabungan data time series dan cross section yang disebut data panel.
Faktor-faktor ekonomi yang mempengaruhi nilai PDRB tidak hanya pada periode waktu saat ini tetapi dipengaruhi oleh periode waktu sebelumnya, hal ini mengidentifikasikan sifat dinamis dari nilai PDRB. Selain itu nilai PDRB di setiap kabupaten/kota memiliki hubungan kebergantungan, sehingga dalam analisis nilai PDRB dibutuhkan metode spasial panel dinamis karena dapat mengakomodasi sifat dinamis dan dependensi spasial serta dapat dilakukan prediksi untuk mempermudah pengambilan kebijakan.
Analisis model spasial membutuhkan matriks pembobot spasial untuk mengukur hubungan keeratan nilai atribut. Matriks pembobot spasial dapat ditentukan berdasarkan teori dari peubah yang digunakan dalam penelitan. Sehingga pada penelitian ini digunakan matriks pembobot berdasarkan informasi jarak yaitu matriks K-nearest neighbor (K-NN). Analisis dengan model dinamis terdapat permasalahan endogenitas untuk mengatasi permasalahan tersebut dapat menggunakan metode pendugaan parameter (SCBB-GMM).
Hasil pengujian dependensi spasial terhadap 20 struktur matriks K-NN diperoleh matriks dengan banyaknya tetangga terdekat K=15 merupakan matriks pembobot yang optimal. Hasil analisis membuktikan bahwa nilai PDRB kabupaten/kota di Provinsi NTT memiliki sifat dinamis dan dependensi spasial hal ini dibuktikan dengan signifikansinya peubah nilai PDRB periode sebelumnya
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
Penerapan Metode Runge-Kutta Orde 4 pada Pemodelan Penularan Penyakit Cacar Monyet
Full text linkMonkeypox is a zoonotic infectious disease caused by the monkeypox virus which belongs to the Orthopoxvirus group. This virus was originally transmitted from animals who innfected with the monkeypox virus to humans, especially rodents and primates. In addition, it can also be transmitted between humans. To make it easier to describe the process of the spread of monkeypox, a mathematical model was created. The mathematical model was made by taking several assumptions based on the nature of charateristics of monkeypox, especially on the pattern of the spread of monkeypox. Based on the assumptions made, this model has two parts to the population, namely the human population is divided into four subpopulations and the animal population is divided in two subpopulations. The model produces a system of non-linear equations that is solved using the Runge-Kutta method of orde 4. The result obtained in this study is a simulation in graphical form. Two simulations were carried out using different parameter values. The parameter is the rate of human infection from animals. The simulation results show that when the value of the human infection rate from animals is reduced, the disease will disappear within a certain time. So that, one of the factor that can be suppressed so that the spread of monkeypox is controlled is the rate of human infection from animals.Cacar Monyet adalah penyakit menular zoonosis yang diakibatkan oleh virus monkeypox yang termasuk dalam kelompok Orthopoxvirus. Virus ini awalnya ditularkan dari hewan yang terinfeksi virus monkeypox ke manusia khususnya hewan pengerat dan primata. Selain itu juga dapat ditularkan antar sesama manusia yang telah terinfeksi virus monkeypox. Untuk memudahkan dalam menggambarkan proses penyebaran penyakit cacar monyet maka dibuat model matematika. Model matematika dibuat dengan mengambil beberapa asumsi berdasarkan sifat atau karateristik dari penyakit cacar monyet khususnya pada pola penyebaran penyakit cacar monyet. Berdasarkan asumsi yang dibuat, model ini memiliki dua bagian populasi, yaitu populasi manusia dibagi menjadi empat sub populasi dan populasi hewan dibagi menjadi dua sub populasi. Model tersebut menghasilkan suatu sistem persamaan nonlinear sebanyak enam persamaan yang diselesaikan menggunakan metode Runge-Kutta orde 4. Hasil yang diperoleh dalam penelitian ini merupakan simulasi dalam bentuk grafik menggunakan aplikasi Python. Simulasi dilakukan sebanyak dua kali dengan menggunakan nilai parameter yang berbeda. Parameter merupakan laju terinfeksi manusia dari hewan. Hasil simulasi memperlihatkan bahwa ketika nilai laju terinfeksi manusia dari hewan dikurangi maka penyakit tersebut akan hilang dalam kurun waktu tertentu. Sehingga salah satu faktor yang dapat ditekan atau dikendalikan agar penyebaran penyakit cacar monyet terkendali adalah laju infeksi manusia dari hewan
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
