Tradisi Hermeneutika dan Penerapannya dalam Studi Komunikasi
Authors: Putra Masri Sareb 
Published: October 2018

Tradisi “hermeneutika” sudah dikenal dalam mitologi Yunani lewat figur Hermes yang dikenal piawai menafsirkan pesan “dunia atas” atau realita sontologis untuk disampaikan kepada manusia. Kemudian, hermeneutika dipraktikkan para pakar untuk menemukan makna hakiki sebuah teks Akitab. Sekolah Frank furt kemudian mengembangkan metode hermeneutika sebagai cabang filsafat yang mencapai puncaknya pada Gadamer. Akan tetapi,hermeneutika baru menarik perhatian para pakar komunikasi Amerika pada 1976. Di Indonesia, hermeneutika belum banyak digunakan untuk studi komunikasi, padahal hermeneutika dapat membongkar makna yang terselubung dibalik realitas yang ada dibalik teks dan wacana secara radikal.

Dalam kehidupan sehari-hari kita sering mendengar kata propaganda. Sayangnya, meskipun mendengar sekedar kata propaganda, dalam pikiran seseorang langsung muncul suatu persepsi yang buruk. Demikian jeleknya citra yang melekat pada propaganda, karena dianggap sebagai suatu kegiatan yang negatif, sehingga tidak jarang ditabuhkan orang. Sebenarnya, propaganda hanyalah alat, sebagai salah satu teknik komunikasi, sebagai bagian dari ilmu komunikasi. Yang buruk bukan propagandanya, tetapi bagaimana atau untuk apa orang yang melakukan atau mempergunakannya. Dengan demikian harus diketahui hakekat propaganda dalam kaitan ilmu komunikasi, yang coba diungkap dalam tulisan ini.

Educational Hybrids in Russian Higher Education
Authors: Senashenko V. S. , Makarova A. A. 
Published: October 2018

The paper applies the conception of social hybridization as an instrument for scientific analysis of national educational reality. This work provides a rationale of the hybrid nature of the national higher education system modernization. The influence of integration preferences on the formation of hybrid educational structures in the system of national higher education is revealed. The hybrid system’s definition is given and the processes of education sphere hybridization are considered. Various aspects of educational hybridization are discussed. In particular, the hybrid nature of the competence approach is emphasized. The authors dwell on the features of hybrid transformations in connection with educational reality and come to a conclusion that today there is an artificial education system in Russia, which generates the distorted educational forms distorting the Russian education system due to a shift of educational activity meanings and the creation of inverted structures. The paper considers the models of hybrid systems based on converted forms. Inversion, like a virus, generates hybrids everywhere. The society and the basic social institutions have been “hybridized” to a large extent. The realistic description of the arising hybrid educational models requires bearing in mind the principle of additionality; otherwise we will have a distorted idea about the transformations of educational reality. We may observe this on the example of the forced implementation of foreign educational models in domestic educational environment. Hybrid educational systems should be “grown” but not implanted.

Authors: Borzova T. A. 
Published: October 2018

The quality of professional education depends on the effectiveness of educational technologies. The Flipped Classroom technology is being successfully tested at the Russian Language Department of Vladivostok State University of Economics and Service within the “Russian Language and Culture of Speech” course. The article analyzes the experience of teaching with the use of the Flipped Classroom technology; it discusses the special features of teaching first-year students, and the principles for organization of self-directed learning process. In flipped learning, self- directed learning is the dominating type of educational activity. Teachers must prepare their students for self-directed learning in the Moodle electronic educational environment, they must motivate them to independently master the theoretical material and to do the practical and controlling assignments and tests. In mixed education, self-directed learning helps to intensify the educational process; forms first-year students’ self-education skills; develops such important personal qualities as independence, activity, consciousness and responsibility. When organizing self-directed learning of students, special attention should be given to the development of practical assignments for testing and control. In teaching the “Russian Language and Culture of Speech” course, the following interactive and electronic tasks are used to form skills and abilities in a reproductive, reconstructive, and creative performance: essays, glossary, mutual reviews, business games, projects, etc. Active methods of control and an electronic survey at the end of the course facilitate the optimization of the self-directed learning process. Considering the special features of mixed education of first-year students, the author defines the main principles for organizing self-directed learning. They are continuity and systematicity; regularity and rhythm; intensity and optimality of workload; interactivity, individualization, feedback and control; effectiveness of activity; development of self-educational skills and such personal qualities as independence, activity, consciousness and responsibility.

AbstractMatrix determinant with the order 2 x 2 and 3 x 3 can be determined by certainly formula (Sarrus method). Nevertheless, that method can’t be used and applied to solve the biggest case such as matrix with order up on it. The Gauss eliminations method is used to finish the matrix determinant with the order 4 x 4 and 5 x 5 by using MATLAB. The calculation results show that the new matrix is produced by row operation elementary like that addition and subtraction between the row have the same determinant. The resulting new matrix determinant from the operation of the exchange between the rows of the matrix has the distinction of beginning so needs to be multiplied by -1. The number of -1 timer involved depending on the multiplicity of exchanges between the line that performed well in the initial matrix or matrix of operating results given. Keywords : Model of solutions, Determinants, Matrix, MATLAB AbstrakMenentukan determinan matriks berordo 2 x 2 dan 3 x 3 dapat menggunakan rumus yang telah ditentukan (metode Sarrus).

Metode eliminasi Gauss digunakan untuk menyelesaikan determinan matriks berordo 4 x 4 dan 5 x 5 dengan menggunakan MATLAB. Hasil perhitungan menunjukkan bahwa matriks baru yang dihasilkan dari operasi baris elementer seperti penjumlahan dan pengurangan antar baris memiliki determinan sama. Determinan matriks baru yang dihasilkan dari operasi pertukaran antar baris memiliki perbedaan dari matriks awal sehingga perlu dikalikan oleh -1. Banyaknya pengali -1 yang dilibatkan bergantung dari banyaknya pertukaran antar baris yang dilakukan baik pada matriks awal maupun matriks baru dari hasil operasi yang diberikan.Kata kunci : Model Penyelesaian, Determinan, Matriks, MATLAB

Published: October 2018

Abstract
The spectral evolution and spectral lag behavior of 92 bright pulses from 84 gamma-ray bursts observed by the Fermi Gamma-ray Burst Monitor (GBM) telescope are studied. These pulses can be classified into hard-to-soft pulses (H2S; 64/92), H2S-dominated-tracking pulses (21/92), and other tracking pulses (7/92). We focus on the relationship between spectral evolution and spectral lags of H2S and H2S-dominated-tracking pulses. The main trend of spectral evolution (lag behavior) is estimated with

(

), where E

p
is the peak photon energy in the radiation spectrum, t + t
0 is the observer time relative to the beginning of pulse −t
0, and

is the spectral lag of photons with energy E with respect to the energy band 8–25 keV. For H2S and H2S-dominated-tracking pulses, a weak correlation between

and k

E
is found, where W is the pulse width. We also study the spectral lag behavior with peak time

of pulses for 30 well-shaped pulses and estimate the main trend of the spectral lag behavior with

. It is found that

is correlated with k

E
. We perform simulations under a phenomenological model of spectral evolution, and find that these correlations are reproduced. We then conclude that spectral lags are closely related to spectral evolution within the pulse. The most natural explanation of these observations is that the emission is from the electrons in the same fluid unit at an emission site moving away from the central engine, as expected in the models invoking magnetic dissipation in a moderately high-σ outflow.
Surface Radioactivity or Interactions? Multiple Origins of Early-excess Type Ia Supernovae and Associated Subclasses
Authors: Jiang Ji-an , Doi Mamoru , Maeda Keiichi , Shigeyama Toshikazu 
Published: October 2018

Abstract
Early-phase Type Ia supernovae (SNe Ia), especially those with luminosity enhancement within the first few days of explosions (“early-excess SNe Ia”), play an irreplaceable role in addressing the long-standing progenitor and explosion issue of SNe Ia. In this paper, we systematically investigate 11 early-excess SNe Ia from subluminous to luminous subclasses. Eight of them are selected from 23 SNe Ia with extremely early-phase optical light curves (“golden” early-phase SNe Ia), and three of them are selected from 40 SNe Ia (including 14 golden samples) with early-phase UV/NUV light curves. We found that previously discovered early-excess SNe Ia show a clear preference for specific SN Ia subclasses. In particular, the early-excess feature shown in all six luminous (91T- and 99aa-like) SNe Ia is in conflict with the viewing angle dependence predicted by the companion-ejecta interaction scenario. Instead, such a high early-excess fraction is likely related to the explosion physics of luminous SNe Ia; i.e., a more efficient detonation happening in the progenitor of luminous SNe Ia may consequently account for the early-excess feature powered by the radiation from a 56Ni-abundant outer layer. The diversity of early-excess features shown in different SN Ia subclasses suggests multiple origins of the discovered early-excess SNe Ia, challenging their applicability as a robust progenitor indicator. Further understanding of the early-excess diversity relies not only on multiband photometry and prompt-response spectroscopy of individual early-excess SNe Ia but also on investigations of the general early-phase light-curve behavior of each SN Ia subclass, which can be realized through ongoing/forthcoming transient survey projects in the near future.
Calibration of Differential Light Curves for Physical Analysis of Starspots
Authors: Basri Gibor 
Published: October 2018

Abstract
This paper presents detailed consideration of methodologies to calibrate differential light curves for accurate physical starspot modeling. We use the Sun and starspot models as a testbed to highlight some factors in this calibration that that have not yet been treated with care. One unambiguously successful procedure for converting a differential light curve into a light deficit curve appears difficult to implement, but methodologies are presented that work in many cases. The years-long time coverage of Kepler provides a strong advantage, but unresolved issues concerning the competing and sometimes similar effects of surface differential rotation versus spot number and size evolution can prevent the confident recovery of correct spot covering fractions in certain cases. We also consider whether faculae are detected by Kepler and/or must be accounted for. We conclude their effects are such that absolute photometry is not required for spot deficit calibrations. To elucidate their signature, we re-examine correlations between absolute brightness, differential variability, and apparent spot coverage for hundreds of Kepler stars with absolute calibrations from Montet et al. The results are similar to theirs, but we draw somewhat different conclusions. Most of the stars in this active solar-type sample are spot-dominated as expected. Partly because of a dearth of longer period stars, the evidence for facular dominance in this sample is both sparse and relatively weak. The facular population exhibits a puzzling lack of dependence on rotation period, which raises questions about the apparent detection of a “facular” signal at short periods.
