In this article, we report on the results of a usability study on the Open Art mobile application conducted in a museum with blind, deaf and sighted/hearing people. The Open Art application was created following the principles of Universal Design to give all types of users the opportunity to use the app on equal terms. The main goal of the study reported here was to assess how the application is used in museum space. We tested 13 people: 1 blind, 5 partially sighted, 3 deaf and hard of hearing as well as 4 sighted/ hearing participants. The results show that the app was generally well received and that its use has a positive influence on museum visiting experience.

Software development process and testing legislative acts

Jakub Kierzkowski

2017 EUNIS journal of higher education IT, T. 2017-1, s. 36-41

The purpose of this paper is to describe legislative process using the terms of software engineering and to propose some new manners of detecting and avoiding defects in new law acts. The idea of software tester’s approach to lawmaking comes from the observation that software development and legislative process are similar. Paragraph 2 contains an explanation of that similarity, definition of some basic software testing terms and a basic discussion on the topic. Paragraph 3 presents some basic software development models. In paragraph 4, one can find a brief description of the legislative process in the Republic of Poland. Paragraph 5 contains a discussion on concepts concerning making better law. I give two new ideas: dividing legislative bills into two documents and setting off the Law Testing Committee, that would lead to better validation and verification of legislative acts.

Tabulate corals across the Frasnian/Famennian boundary: architectural turnover and its possible relation to ancient photosymbiosis

Mikołaj K. Zapalski, Jakub Nowicki, Michał Jakubowicz, Błażej Berkowski.

2017 Palaeogeography, Palaeoclimatology, Palaeoecology, T. 487, 1 December, s. 416-429

The Frasnian-Famennian biodiversity crisis has traditionally been considered one of the “Big Five” mass extinctions; among deep changes in the biosphere, it almost completely erased shallow-water marine ecosystems like coral-stromatoporoid reefs, which were widespread on the carbonate platforms in the Devonian. The high biodiversity of bioconstructors during the Givetian-Frasnian acme of Palaeozoic reef development contrasts sharply with very low biodiversity levels during the Famennian. One of major bioconstructing groups in the Palaeozoic was tabulate corals. A statistical analysis of colony architecture of Givetian-Frasnian and Famennian tabulates from the Holy Cross Mountains (Poland) reveals that Givetian and Frasnian tabulate faunas had smaller corallite diameters and higher colony integration, compared to the Famennian faunas. A similar pattern occurs in the Devonian of the Ardennes. In the Holy Cross Mountains the biodiversity drastically decreases in the Late Frasnian. We interpret Givetian-Frasnian tabulate communities as generally photosymbiotic, and their Famennian counterparts as generally aposymbiotic. In Recent corals temperatures above 32 °C are generally considered as a threshold for bleaching (expulsion of photosymbionts), a literature review indicates that in the late Frasnian sea surface temperatures exceeded this threshold. This leads to a discussion of the late Frasnian rise of temperature as a contributing cause of extinction of photosymbiotic bioconstructors, and possibility of a Late Devonian “bleaching event”. © 2017 Elsevier B.V.

The National Repository of Theses: A Short Polish Case Study

Jarosław Protasiewicz, Małgorzata Stefańczuk, Andrzej Sadłowski

2017 EUNIS journal of higher education IT, T. 2017-1, s. 113-120

The aim this study is to outline the main assumptions and challenges that occurred while introducing the national repository of theses in Poland. More specifically, we discuss the legal basis and other conditions of the repository, its architecture, implemented business processes, and some the most interesting technical details and performance statistics. Particularly, we show that a simple datastore based only on a filesystem could be more efficient and cheaper than a NoSQL database, which is quite fashionable nowadays. Presented comments and remarks regarding

development and deployment of the information system and selected statistics of the working software may help other parties to improve their repositories or take a decision regarding new solutions.

Using coefficient K to distinguish ambient/focal visual attention during map viewing

Krzysztof Krejtz, Arzu Coltekin, Andrew Duchowski, Anna Niedzielska

2017 Journal of Eye Movement Research, T. 10, Z. 2, s. 1-13

We demonstrate the use of the ambient/focal coecient K for studying the dynamics of visual behavior when performing cartographic tasks. Participants viewed a cartographic map and satellite image of Barcelona while performing a number of map-related tasks. Cartographic maps can be viewed as summary representations of reality, while satellite images are typically more veridical, and contain considerably more information. Our analysis of traditional eye movement metrics suggests that the satellite representation facilitates longer fixation durations, requiring greater scrutiny of the map. The cartographic map affords greater peripheral scanning, as evidenced by larger saccade amplitudes. Evaluation of K elucidates task dependence of ambient/focal attention dynamics when working with geographic visualizations: localization progresses from ambient to focal attention; route planning fluctuates in an ambient-focal.ambient pattern characteristic of the three stages of route end point localization, route following, and route confirmation.

Zróżnicowanie innowacyjności przedsiębiorstw hotelarskich w Polsce − studium empiryczne

Marcin Olszewski, Barbara Kowalczyk


The competitiveness of tourism enterprise largely depends on its ability to create
innovations. This empirical article presents the results of the quantitative study carried out in
400 Polish hotels. The aim of this article is to identify the level of innovation activity in hotel
companies in Poland and its differentiation in terms of size, standard and affiliation to a hotel
chain. The first part of the article presents a review of previous studies on the differentiation
of the innovation activity in the hotel industry. The second part introduces the methodology of
empirical research. The results are presented in the third part. The survey shows that the most
innovative hotels in Poland are large and belong to international hotel chains.
