The paper considers the modern problems in prediction of hazardous geological processes in the XXI century. It is noted that the peculiarities of the prediction of the most hazardous geological processes (landslides, mudflows, etc.) are connected with global climatic changes and a technogenic factor. The assessment of climatic changes and the most largest catastrophic disasters was carried out with use of the typification of atmospheric circulation in the Northern hemisphere, developed by B. L. Dzerdzeevskii. The data of the typification for the period from 1899 to 2017 can be found on the Internet website www. atmospheric-circulation.ru in open access. The major disasters are considered that caused an activation of landslides and mudflows. The interaction of natural and technogenic factors is described during these disasters. The prediction took into consideration the changes in solar activity and features of space weather.

We propose a project of the meter wavelength range solar spectropolarimeter designed for a ground-based network developing for space weather forecast. The Software-Defined Radio (SDR) solution is chosen to meet such instrument network requirements as specification identity, low cost, possibility of controlling and transmitting data remotely via the Internet. Along with these requirements, the proposed SDR solution allows us to measure Stokes I and V easily, which contrasts the proposed instrument with e-CALLISTO network spectropolarimeters, most of which can record only one linear polarization. Deployment of such instruments at various longitudes will allow continuous observation of type II bursts, often related to coronal mass ejections (CMEs) — the most geoeffective solar activity events that affect the space weather significantly.

The Right

The study of law focuses, among other aspects, on important issues relating to equality, fairness and justice in as far as free access to information and knowledgeis concerned. The launching of the Open Access to Law Movement in 1992, the promulgation of the Durham Statement on Open Access to Legal Scholarshipin 2009, and the formation of national and regional Legal Information Institutes (LIIs) should serve as an indication of how well the legal world is committed to freely publishing and distributing legal information and knowledge through the Internet to legal practitioners, legal scholars and the public at large aroundthe world. In order to establish the amount of legal scholarly content which is accessible through open access publishing innovations and initiatives, this studyanalysed the contents of websites for selected open access resources on the Internet internationally and in South Africa. The results of the study showed that there has been a steady developing trend towards the adoption of open access for legal scholarly literature internationally, while in South Africa legal scholarly literature is under the control of commercial publishers. This should be an issue for the legal scholarship which, among its focus, is to impart knowledge about the right of access to information and knowledge.

<p>Detailed logs of students’ computer use, during independent study sessions, were captured in an open-access computer laboratory. Each log consisted of a chronological sequence of tasks representing either the application or the Internet domain displayed in the workstation’s active window. Each task was classified using a three-tier schema according to its likely context of use: The top-level categories being <em>Academic</em>, <em>Communication</em>, <em>Information</em>, <em>Recreation</em> and <em>Applications</em>. Students switched tasks frequently – median task duration was only 31 seconds. Approximately 30% of all tasks were <em>Academic</em> with the majority of these involving the university’s learning management system. <em>Communication</em> and <em>Recreation</em> tasks accounted for 18% and 9% of tasks respectively. Up to one half of all tasks were not related to study. Multitasking was very common during independent study sessions, particularly when <em>Communication</em> tasks were active. This study confirms that students are likely to regularly switch tasks, attend to distracting tasks, and multitask during independent study. Each one of these behaviours has the potential to negatively impact on students’ learning, and when combined they indicate that students are relatively inefficient at managing competing tasks and their time when studying.</p>

This article introduces our ongoing project “Construction of a Century Solar Chromosphere Data Set for Solar Activity Related Research”. Solar activities are the major sources of space weather that affects human lives. Some of the serious space weather consequences, for instance, include interruption of space communication and navigation, compromising the safety of astronauts and satellites, and damaging power grids. Therefore, the solar activity research has both scientific and social impacts. The major database is built up from digitized and standardized film data obtained by several observatories around the world and covers a timespan more than 100 years. After careful calibration, we will develop feature extraction and data mining tools and provide them together with the comprehensive database for the astronomical community. Our final goal is to address several physical issues: filament behavior in solar cycles, abnormal behavior of solar cycle 24, large-scale solar eruptions, and sympathetic remote brightenings. Significant progresses are expected in data mining algorithms and software development, which will benefit the scientific analysis and eventually advance our understanding of solar cycles.
