Abstract MOOC appearance has produced, in a first phase, more discussions than contributions. Despite pessimistic opinions or those catastrophic foreseeing the end of the classic education by accepting MOOC, the authors consider that, as it is happening in all situations when a field is reformed, instead of criticism or catastrophic predictions, an assessment should be simply made. MOOC will not be better or worse if it is discussed and dissected but can be tested in action, perfected by results, or abandoned if it has no prospects. Without testing, no decision is valid. A similarity between the MOOC appearance and the appearance of the idea of flying machines heavier than air can be made. In the flight case, the first reaction was a strong negation (including at Academies level) and only performing the first independent flight with an apparatus heavier than air has shifted orientation from denial to contributions. So, practical tests clarified the battle between ideas. The authors of this article encourage the idea of testing–assessment and, therefore, imagined and proposed one software for quickly assess whether MOOC produces changes in knowledge, by simply transferring courses from ‘face-to-face’ environment into the virtual one. Among the methods of statistical analysis for student behavioral changes was chosen the Keppel method. It underpins the assessment method of this work being approached using both the version with one variable and also with three variables. It is intended that this attempts to pave the way for other series of rapid assessment regarding MOOC effects (using other statistical methods). We believe, that this is the only approach that can lead either to improve the system or to renunciation.

Content published in social media (SM) can be motivating. It can induce action, stimulate demand, and shape opinions. On the other hand, it can demotivate, cause helplessness, or overwhelm with information. Still, the impact of SM is not always the same. The paper aims to analyse the relations between sex, personality, and the way social media is used and motivation to take specific actions. The conclusions are founded on a survey (n = 462). The data were analysed with statistical methods. The study revealed that the use of SM has a significant impact on the motivation to act. Browsing through descriptions and photographs of various achievements posted by others in SM increased the intrinsic motivation of the respondents. Positive comments and emojis had a similar effect. Moreover, women and extraverts noted a significantly greater impact of SM on their intrinsic motivation concerning health and beauty effort, travel, hobby, and public expression of opinions than men and introverts. The results can be useful to recruiters. Extravert women that are open to cooperation, thorough, and well-organised are more likely to be active in SM.

The aim of this paper is to assess the relation between the character of the interpretive trail and the imposition of a charge on the entrance. This was done using the discrete choice experiment that involves eight attributes, seven of which are with three levels: the overall character of the trail, the way that the route signs are used in the terrain, the ways of providing information, the length of the trail, the way of the routing, the focus of the trail, and the price of the entrance. There is also one with two levels that involves the existence of the places for rest. The fractional factorial design was used (the orthogonal main effects plan) and the Multinomial Logit Model was used in analyzing the data. The 2,830 choices were done by random sampled visitors from eight tourist locations in the Tourist Regions of the Šumava Mts. and South Bohemia during the summer season 2012. The impact of the character of the trail was especially detected in the model. Except for that, the equipment of the trail and its length have had the fundamental impact on the choice of the trail as well. Those longer and worse equipped trails have a significantly lower degree of utility for the respondents. What is quite surprising is that the respondents refused the ecotourism elements of the interpretive trails, such as the possibility of going through the trail on horseback or the accompaniment of an expert who would provide some comments, as it is common to do this at historical attractions within those sightseeing paths.

An experiment was performed to determine the effect (if any) of sloppy typing and reproduction upon the effectiveness of a written technical message. The variables tested were the margins, the way in which corrections were made, and the reproduction of the message. Approximately seven hundred subjects in five definably different audiences were tested. Measures were taken of comprehension, reading time, judgment of the author's credibility, and judgment of the author's competence as a writer. Five main effects and five interactions were found at the 0.05 level of probability. Each variable, each measure of the effectiveness of the message, and each audience was involved in one or more of these effects. In each main effect and each interaction subject to easy interpretation, the unaltered form (good typing and good reproduction) of the variable(s) concerned appeared to be the more effective.

The problems associated with vision through mesh window screening materials are discussed and a laboratory experiment using a 1/8th replicate 2th factorial design is described which shows the relative effects on vision of main effects and first-order interactions. Two criteria of visibility were used: a Landolt ring, measuring changes in visual acuity, and paired ratio scaling giving direct magnitude estimates of “ease of seeing” through the material. The laboratory results were validated in a short field experiment in which the effects on visibility of three isolated variables was determined by paired comparisons. Some suggestions for future experiments are also discussed.

 ABSTRAKDialect, according to many Arabic linguists, refers to language and letters used by a particular community that cause differences in the pronunciation even in the way particular letters are used among different societies.Dialect is variation in language depending on the users, that is the language as it is commonly used by the language users. Dialect; therefore, is dependent upon who use the language and where the users of the language reside. The geographical aspects shape the regional dialect and the social aspects shape the social dialect.This descriptive quantitative research aims to investigate the factors and aspects that shape some dialects in Arabic.The findings demonstrate that the factors influencing dialects include the geographical width of the area, the cross-language interaction and the different strata of the society.Keywords: Dialect, Arabic linguists, Causes and Elements

The problems of the enterprises’ investments into ecological innovations for saving the natural resources are considered in the article. The conditions and factors influencing introduction of ecological innovations in the sphere of economy of Russia are described. The dynamics of the share of the enterprises performing ecological innovations in the total quantity of the enterprises which had completed their innovations is systematized, as well as the dynamics of the special costs connected with ecological innovations. Though the legislation offers some special tax benefits for the enterprises performing their research and development connected with the ecological innovations, problems still exist. The author proves that the implementation of the technologies developed by such “preferential” research and development does not make much profit for the producer of innovations; a little share of the enterprises performing ecological innovations is also revealed. Comparative, economical and statistical methods of the analysis were used for the justification of the authors conclusions. The achieved results of the research can be used in the sphere of forming of regional innovation policy, in the sphere of the development of the standard legal framework of stimulation of ecological innovations in the economy of Russia and other countries.
