    Digitalizating rural areas: A traditional context

    Full text link
    Digitalizing the existing territories is widely declared and procreated in the modern world. The process has become widespread in developed countries and is gaining momentum in developing countries; also attracting a lot of studies in economics, technology, and political science. We argue the necessity of philosophical attitude to cope with the essentials of digitalization. Mostly, the use of philosophy in the matter comes with aspects usually ignored in quantitative methodologies. Actual qualitative reference of unfolding digital nets for rural territories, still representing numerous semantics of a traditional life-world, helps bringing to the limelight opportunities overlooked in intensive indicators and their capacity to describe the actual social and cultural process involved in territorial digitalization. © Published under licence by IOP Publishing Ltd

    ABSTRAKBerkembangnya pariwisata di tengah masyarakat membawa pengaruh terhadap kehidupan sosial budaya. Pariwisata selalu mempertemukan dua atau lebih kebudayaan yang akan menghasilkan berbagai proses perubahan seperti akulturasi, dominasi, asimilasi, adopsi, adaptasi dan sebagainya. Wisatawan mancanegara yang berkunjung ke Lhoknga telah membawa pengaruh terhadap masyarakat lokal di daerah sekitar objek wisata. Penelitian ini bertujuan untuk mengetahui dampak pariwisata terhadap perubahan sosial budaya masyarakat dan mengetahui bentuk perubahan sosial budaya yang terjadi pada masyarakat Lhoknga akibat perkembangan pariwisata di Mukim Lhoknga. Metodologi penelitian ini menggunakan pendekatan kualitatif dengan model studi deskriptif. Pengumpulan data dilakukan dengan wawancara mendalam dan observasi. Dari hasil penelitian menunjukkan bahwa terjadinya perubahan sosial budaya pada masyarakat lokal di Mukim Lhoknga, Kecamatan Lhoknga Kabupaten Aceh Besar. Namun perubahan yang dimaksud masih dikategorikan perubahan secara mikro, karena tidak membawa pengaruh yang mendalam pada kehidupan masyarakat lokal. Dampak pariwisata terhadap perubahan sosial budaya masyarakat dapat dipilah menjadi dua yaitu dampak positif dan dampak negatif. Dampak positifnya yaitu dengan adanya pariwisata telah membuka lapangan kerja baru bagi masyarakat lokal yang dapat meningkatkan pendapatan ekonomi, mampu menguasai bahasa asing, seperti bahasa Inggris, Jepang. Terbukanya akses bagi masyarakat lokal ke jaringan yang lebih luas, memperlihatkan keindahan alam dan budaya yang tak lepas dari rasa untuk meningkatkan persaudaraan dalam lingkungan nasional dan internasional Sedangkan dampak negatif yaitu, lunturnya budaya lokal (tradisional) akibat masuknya budaya luar (modern). Adapun bentuk-bentuk perubahan dapat dilihat dari dua segi yaitu perubahan segi sosial dan perubahan dari segi budaya. Bentuk perubahan dari segi sosial yaitu terjadinya perubahan struktur sosial masyarakat lokal dengan beralihnya sektor pekerjaan dari petani atau nelayan ke sektor industri, Meningkatnya keinginan untuk berpendidikan tinggi, sedangkan perubahan dari segi budaya yaitu terjadinya perkawinan dari dua unsur budaya yang berbeda, perubahan pada penggunaan bahasa, perubahan cara berpakaian dan perubahan perilaku dalam keluarga.Kata Kunci : Pariwisata, Wisatawan Asing, Perubahan Sosial, Perubahan Budaya.Banda Ace

    Оценка влияния эффекта Доплера на качество радиосвязи в условиях высокоскоростного движения

    The article proposes a methodology for evaluating radio signal distortions caused by Doppler effect (DE; also, Doppler shift) under the conditions of highspeed train traffic (HSR, high-speed rail). The objective of the work is to develop criteria for assessing quality of radiocommunications with moving objects in HSR environment. For this, a technique is proposed for calculating the probability of an error arising from Doppler effect. A rationale for relevance of the topic is that radiocommunications are used on railways for controlling train traffic and ensuring safety and achieving required quality of radio signals is a major challenge. Quality assessment is especially important for organization of broadband communication channels with locomotive drivers using mobile networks. To solve this problem, a model for assessing quality of radiocommunication influenced by DE is considered. Distortions of signals in a radio channel due to DE are proposed to be estimated using the reduced dispersion of the total error, which consists of two components: dynamic and interference. Calculations of the total reduced signal error and the error probability for speeds above 100 km/h are described. Estimates of the effect of DE on a coherent receiver, in which errors may occur due to changes in duration of radio pulses, are suggested. Effectiveness of the receiver’s automatic frequency control (AFC) system is analysed as a means of challenging DE. For this, the concept of an instantaneous spectrum of parasitic frequency modulation due to DE was introduced and quality of radio communication was calculated using the reduced dispersion of the total error. The efficiency of using AFC has been proven after comparing the evaluations of reception quality with and without AFC in the form of the ratio of error probabilities. The features of the use of mobile communications on railways under the conditions of DE are formulated.В статье предложена методика оценки искажений радиосигнала от действия эффекта Доплера (ЭД) в условиях высокоскоростного движения поездов. Цель работы – разработка критериев оценки качества радиосвязи с подвижными объектами в условиях высокоскоростного движения поездов. Для этого предложена методика расчёта вероятности ошибки, возникающей в результате действия эффекта Доплера. Дано обоснование актуальности темы для железнодорожного транспорта, где посредством радиосвязи осуществляется управление движением поездов и обеспечение безопасности. Достижение требуемого качества радиосигналов является главной задачей. Особенно важна оценка качества при организации широкополосных каналов связи с машинистами подвижных составов с помощью сетей мобильной связи. Для решения этой задачи рассмотрена модель оценки качества радиосвязи в условиях действия ЭД. Искажения сигналов в радиоканале за счёт эффекта Доплера предложено оценивать с помощью приведённой дисперсии суммарной погрешности, которая состоит из двух составляющих: динамической и помеховой. Представлены расчёты суммарной приведённой погрешности сигнала и вероятности ошибки для скоростей движения выше 100 км/ч. Кроме того, даны оценки влияния ЭД на когерентный приёмник, в котором могут возникать ошибки за счёт изменений длительности радиоимпульсов.Приведён анализ эффективности системы автоматической подстройки частоты (АПЧ) приёмника как средства борьбы с ЭД. Для этого введено понятие мгновенного спектра паразитной частотной модуляции за счёт ЭД, и с помощью приведённой дисперсии суммарной погрешности рассчитано качество радиосвязи. Эффективность использования АПЧ доказана после сравнения оценок качества приёма с АПЧ и без него в виде отношения вероятностей ошибок. Сформулированы особенности использования мобильной связи на железнодорожном транспорте в условиях действия ЭД

    X-ray line formation in the spectrum of SS 433

    Full text link
    The mechanisms for the formation of X-ray lines in the spectrum of SS 433 are investigated by taking into account the radiative transfer inside the jets. The results of Monte Carlo numerical simulations are presented. The effect of a decrease in line intensity due to scattering inside the jet turns out to be pronounced, but it does not exceed 60% in magnitude on the entire grid of parameters. The line broadening due to scattering, nutational motion, and the contribution of satellites can lead to overestimates of the jet opening angle Θ\Theta from the line widths in Chandra X-ray observations. The fine structure of the lines turns out to be very sensitive to the scattering effects. This makes its investigation by planned X-ray observatories equipped with high-resolution spectrometers (primarily Astro-H) a powerful tool for diagnosing the parameters of the jets in SS 433.Comment: 23 pages, 14 figures, to be published in Astronomy Letters, v. 38, n. 7, p. 443 (2012

    Global warm-up makes the political agenda on highest levels. However, the science should make itself publicly heard, and not in the part of fundamental studies of nature only, but in the part of social science and social research of administrative tools as well. We offer three circles of quest that attract numerous scholars in the science of management and administration touching the context of complementing new ecological imperatives in running the rural territories: (1) the relevance of new environmental mentality to practical principles of existing rural administrations, (2) the communication challenges, opportunities, and risks in introducing new qualitative criteria into existing social technologies, which dominate modern rural administration patterns, (3) the importance of alternative in technological development of modern rural territories with a high agrarian overload, including the managing of alternative energy introduction, and trial of unprecedented technological schemes. © The Authors, published by EDP Sciences, 2020
