Opis: : Technical debt is a well understood and used concept in IT development. The metaphor, rooted in the financial world, captures the amount of work that development teams owe to a product. Every time developers take a shortcut within development, the technical debt accumulates. Technical debt identification can be accomplished via manual reporting on the technical debt items, which is called self-admitted technical debt. Several specialised methods and tools have also emerged that promise to measure the technical debt. Based on experience in the community, the impression emerged that the measured technical debt is of a significantly different amount than the self-admitted debt. In this context, we decided to perform empirical research on the possible gap between the two. We investigated 14 production-grade software products while determining the amount of accumulated technical debt via (a) a self-admitting procedure and (b) measuring the debt. The outcomes show clearly the significant difference in the technical debt reported by the two methods. We urge development and quality-assurance teams not to rely on technical debt measurement alone. The tools demonstrated their strength in identifying low-level code technical debt items that violate a set of predefined rules. However, developers should have additional insight into violations, based on the interconnected source code and its relation to the domain and higher-level design decisions.

Opis: Remarkable immunomodulatory abilities of mesenchymal stem cells, also called multipotent mesenchymal stromal cells or medicinal signaling cells (MSCs), have entailed significant advances in veterinary regenerative medicine in recent years. Despite positive outcomes from MSC therapies in various diseases in dogs and cats, differences in MSC characteristics between small animal veterinary patients are not well-known. We performed a comparative study of cells' surface marker expression, viability, proliferation, and differentiation capacity of adipose-derived MSCs (ADMSCs) from dogs and domestic cats. The same growth media and methods were used to isolate, characterize, and culture canine and feline ADMSCs. Adipose tissue was collected from 11 dogs and 8 cats of both sexes. The expression of surface markers CD44, CD90, and CD34 was detected by flow cytometry. Viability at passage 3 was measured with the hemocytometer and compared to the viability measured by flow cytometry after 1 day of handling. The proliferation potential of MSCs was measured by calculating cell doubling and cell doubling time from second to eighth passage. Differentiation potential was determined at early and late passages by inducing cells toward adipogenic, osteogenic, and chondrogenic differentiation using commercial media. Our study shows that the percentage of CD44+CD90+ and CD34−/− cells is higher in cells from dogs than in cells from cats. The viability of cells measured by two different methods at passage 3 differed between the species, and finally, canine ADMSCs possess greater proliferation and differentiation potential in comparison to the feline ADMSCs.

Opis: This study examines the effects of COVID-19-related measures on the mathematics achievement of university students in social sciences in Slovenia. Our particular concern was to compare two student populations (pre-pandemic and pandemic) in terms of factors affecting student performance in mathematics courses. Data were collected over nine consecutive academic years (from 2013–2014 to 2020–2021) and analyzed using two-stage structural equation modelling (SEM). The analyses confirmed that the conceptual model developed before the pandemic was applicable during the pandemic period. For both populations (pre-pandemic and pandemic), mathematics confidence, perceived level of math anxiety, background knowledge from secondary school, and self-engagement in mathematics courses at university were confirmed as factors influencing mathematics achievement. Moreover, both populations perceived the effects of the factors in the same way, and the magnitude of the effects is comparable. The rather high values of determination coefficient for mathematics achievement (greater than 0.66 for both student populations) indicate that the variables “Perceived Level of Math Anxiety” and “Self-Engagement in Mathematics Course at University” together explain a significant proportion of the total variance before and during the pandemic. Consequently, the results of our case study indicated that pandemic measures did not have a significant impact on our students’ mathematics achievement. Although a more in-depth study of a broader sample of academic courses would be needed to confirm our findings, our experience indicates that mathematics courses at the tertiary level of education can be successfully delivered online.

Opis: Translating does not simply consist of replacing words in the source language with words in the target language, it is influenced by the person doing the translating and the public for which the translation is intended. We wanted to examine if translators and their surrounding culture influence the way literary works are translated. We compared Mark Twain’s The Adventures of Tom Sawyer and its three Slovenian translations published in 1921, 1947 and 1960. We based our research on the social and political background of the periods in which the translations were made, mostly focusing on 1947 and the anti-Catholic movement in Slovenia, which was influenced by the Soviet Union. Therefore, we selected from the original text 30 passages that mention religion and the Church. In the analysis we have compared the three Slovene translations and determined that out of 30, only 10 examples exhibited a change in the meaning. One such example was found in the 1921 translation, six in the 1947 translation and four in the 1960 translation, one of the latter examples even expanded the meaning of a religious elements.

Opis: Purpose: This paper aims to give an empirical overview of the ‘privatization’ of security (or, in a more narrow sense, policing) services within the former countries of the Socialist Federal Republic of Yugoslavia namely, Slovenia, Croatia, Serbia, Kosovo, Bosnia-Herzegovina, Macedonia and Montenegro. Observations are put in light of the extant literature on private policing worldwide. Design/Methods/Approach: The paper draws on a literature review of academic publications, NGO-reports and other relevant written sources. Findings: Although it is not possible to offer a full picture of the current developments in the region, we argue that the rise of private security markets shows significant variety throughout former Yugoslavian countries, as does the level of state regulation. Moreover, contrary to the views of doomsayers critical of the provision of commercial security, academics and observers alike are optimistic about private security personnel becoming a legitimate and stabilizing presence in post-conflict zones such as the Balkans. Research implications: The persistence of divergence in private policing trajectories within the former Yugoslavia underscores the need for more detailed cross-national studies that take account of differences, as well as similarities, in how commercial security industries are governed and regulated by state institutions. Practical implications: Public as well as private policy-makers in the field of security serve as appropriate anchor points to facilitate, direct and regulate private policing activities across the former Yugoslav republics. Originality/Value: The growing body of knowledge on private policing is heavily suffused by predominantly North American, Canadian, British and Australian studies. Nonetheless, research from countries outside the English speaking world has much to contribute to an understanding of private security industries. An examination of the Balkan countries that emerged from the breakup of Yugoslavia is particularly interesting when viewed as a post-conflict legacy.
