- ItemTowards a General Definition of Modeling(2010-11-24) Podnieks, KarlisWhat is a model? Surprisingly, in philosophical texts, this question is asked (sometimes), but almost never – answered. Instead of a general answer, usually, some classification of models is considered. The broadest possible definition of modeling could sound as follows: a model is anything that is (or could be) used, for some purpose, in place of something else. If the purpose is “answering questions”, then one has a cognitive model. Could such a broad definition be useful? Isn't it empty? Can one derive useful consequences from it? I'm trying to show that there is a lot of them.

- ItemSoftware Testing Overview on Different Generalization Levels(2013-08-01) Kuļešovs, Ivans; Arnicane, Vineta; Arnicans, Guntis; Borzovs, JurisThere are many different views on software testing co-exist even within the borders of one organization. That is why we have decided to prepare software testing overview on metalevel indicating main influencers that make this difference. While gathering the details about meta-level elements we have performed some structuring of elements from lower level of software testing such as testing oracles and testing approaches, methods, and techniques. The overview preparation has resulted into laying the scientific basis under proper use of such terms as testing approach, testing method, and testing technique. Our overview could be useful for making ordered introduction into software testing for fresh minds of testing newbies, while we recognize that in practice it can be hard to make sharpcut edges between some software testing elements described here.
- ItemInventory of Testing Ideas and Structuring of Testing Terms(2013-08-15) Kuļešovs, Ivans; Arnicāne, Vineta; Arnicāns, Guntis; Borzovs, JurisStudy includes software testing terms and ideas inventory, software testing overview and schematization on meta-level and structuring of lower level elements related to software testing such as testing oracles, testing levels, software quality characteristics, testing approaches, methods, and techniques. Main testing controversies are collected and described. Scientific basis is laid under proper use of such terms as testing approach, testing method, and testing technique.

- ItemInformācijas tehnoloģijas terminu lietošanas paradumi publiskajā saziņā(2013-11-23) Borzovs, Juris; Ilziņa, Ilze Irēna; Keiša, Iveta; Pinnis, Mārcis; Vasiļjevs, AndrejsInformācijas un komunikācijas tehnoloģijas (IKT) termini galvenokārt tiek radīti angļu valodā un pēc tam lokalizēti citās valodās. Valodu morfoloģisko un terminrades tradīciju atšķirību dēļ šāda lokalizācija mēdz būt diezgan haotiska. Latvijas IKT terminu lokalizētāji ir izstrādājuši samērā stingru, t. s. kvazialgoritmisko pieeju, ko aprobējuši vairāk nekā 15 gadu laikā. Šajā rakstā uz biežāk lietoto terminu piemēra parādīta pieejas dzīvotspēja. Noraidīts izplatītais uzskats, ka IKT terminu lokalizējumi piesārņo latviešu valodu ar svešvārdiem. Analizēta oficiāli apstiprināto terminu lietojamība tekstos un iemesli, kādēļ tie dažkārt sastop ikdienas lietotāju pretestību.
- ItemTerminology localization guidelines for the national scenario(2014-04-14) Borzovs, Juris; Ilziņa, Ilze; Keiša, Iveta; Pinnis, Mārcis; Vasiļjevs, AndrejsThis paper presents a set of principles and practical guidelines for terminology work in the national scenario to ensure a harmonized approach in term localization. These linguistic principles and guidelines are elaborated by the Terminology Commission in Latvia in the domain of Information and Communication Technology (ICT). We also present a novel approach in a corpus-based selection and an evaluation of the most frequently used terms. Analysis of the terms proves that, in general, in the normative terminology work in Latvia localized terms are coined according to these guidelines. We further evaluate how terms included in the database of official terminology are adopted in the general use such as newspaper articles, blogs, forums, websites etc. Our evaluation shows that in a non-normative context the official terminology faces a strong competition from other variations of localized terms. Conclusions and recommendations from lexical analysis of localized terms are provided. We hope that presented guidelines and approach in evaluation will be useful to terminology institutions, regulative authorities and researchers in different countries that are involved in the national terminology work.
- ItemiOS Applications Testing - Multivocal Sources(2014-05-23) Kulesovs, Ivans
- ItemiOS Applications Testing(2014-05-23) Kulesovs, IvansMobile applications conquer the world, but iOS devices hold the major share of tablets market among the corporate workers. This study aims to identify the aspects (i.e. features and/ or limitations) that influence the testing of the native iOS applications. The aspects related to general mobile applications testing are identified through the systematic literature review of academic sources. iOS applications testing aspects are identified through the review of non-academic (multivocal) literature sources. The identified aspects are merged and discussed in detail using the reviewed sources and based on the author’s professional experience in iOS applications testing. The references to credible sources are provided in order to support the professional experience findings. The study eliminates the gap that exists in the academic world in regards to iOS applications testing. The practitioners are also encouraged to fulfill their iOS applications testing strategies with the identified aspects.
- ItemAutomated Testing of iOS Apps: tTap Extension for Apple UIAutomation(2015) Kulesovs, IvansMobile apps tend to extend or even substitute the existing IT solutions. In the corporate world, according to the statistics, the preference is given to iOS devices. The complexity of the apps increases together with the apps quantity. This also increases the need for automated testing. In a course of the study we compare the existing test automation solutions for iOS apps and describe some extensions for Apple UIAutomation tool. We have also created our own extension called tTap that improves the existing ones and solves several issues that does not work in the clean UIAutomation. We describe the implementation details of our extension and share the practical experience of testing iOS apps using it. We also describe the part of our test lab solution, while the description of the full test lab is planned in the consecutive studies.

- ItemFactors Affecting Attrition among First Year Computer Science Students: the Case of University of Latvia(2015-03-18) Borzovs, Juris; Niedrite, Laila; Solodovnikova, DarjaThe purpose of our study was to identify reasons for high dropout of students enrolled in the first year of the computer science study program to make it possible to determine students, who are potentially in risk. Several factors that could affect attrition, as it was originally assumed, were studied: high school grades (admission score), compensative course in high school mathematics, intermediate grades for core courses, prior knowledge of programming. However, the results of our study indicate that none of the studied factors is determinant to identify those students, who are going to abandon their studies, with great precision. The majority of the studied students drop out in the 1st semester of the 1st year, and the dropout consists mostly of those, who do not really begin studies. Therefore, one of the main conclusions is such that the planned activities of informing about the contents of the program should be carried out, and the perspective students should be offered a possibility to evaluate their potential to study computer science before choosing a study program.
- ItemComputer Programming Aptitude Test as a Tool for Reducing Student Attrition(2015-03-20) Borzovs, Juris; Niedrite, Laila; Solodovnikova, DarjaThe stable trend to lose from one-third to half of students in the first study year of computing studies motivated us to explore, which methods are used to determine in advance such applicants, who have no change to overcome the first study year. Initially, a research about the factors influencing the attrition in Faculty of Computing at the University of Latvia was conducted. The research revealed that the trend of non-beginning studies might indicate the wrong choice of the study field and possible lack of understanding of what is programming by enrolled students (applicants as well as pupils). The study provides the review of the situation with programming aptitude tests in the world, which could serve as one of the solutions to the dropout reduction. An action plan is proposed, which is based on the exploration of students and evaluation of activities already conducted at the Faculty of Computing of the University of Latvia to reduce dropout (School of Young Programmers, Compensative Course in High School Mathematics, Mentoring programs). Moreover, the supplementation of these activities by one of the existing programming attitude tests (or a combination of several tests) or a necessity to develop a new similar test is considered.
- ItemTruth Demystified(2015-11-05) Podnieks, KarlisFor further development, see Karlis Podnieks in ResearchGate. How could we recognize truth, if we only have models, means of model-building, and the history of their evolution? Where is the truth in the cloud of models – with so many of them already gone with the wind? We can define truths as more or less persistent invariants of successful evolution of models and means of model-building. What is true, will not change in the future (for some time, at least). This approach to truth could be named demystified realism (or, demystified theory of truth) – the kind of realism based on a minimum of metaphysical assumptions. (“Robotic realism” also would be appropriate, but the term is occupied already.)
- ItemExplanation and Understanding in a Model-Based Model of Cognition(2017-11-20) Podnieks, KarlisThis article is an experiment. Consider a minimalist model of cognition (models, means of model-building and history of their evolution). In this model, explanation could be defined as a means allowing to advance: production of models and means of model-building (thus, yielding 1st class understanding), exploration and use of them (2nd class), and/or teaching (3rd class). At minimum, 3rd class understanding is necessary for an explanation to be respected.
