Opis: Background and Objective: During the COVID-19 pandemic, women faced unique employment-related stressors, including higher exposure to unstable working conditions, increased workload changes due to motherhood, and greater risk of infection in certain jobs. This study explores how these factors influence women’s anxiety and subjective well-being, aiming to identify vulnerable groups. Materials and Methods: 230 employed Slovene women, aged from 19 to 64 years (M = 32.60, SD = 10.41), participated in an online survey containing a State-Trait Anxiety Inventory (STAI-6), WHO-5 Well-being Index, and a set of questions regarding their occupation and demographic profile. Hierarchical linear regressions and chi-squared tests were performed. Results: The risk of job or income loss significantly predicted an increase in anxiety levels. However, despite fear of infection, none of the work-related variables predicted a significant decrease in subjective well-being. Women reporting risk of job or income loss are predominantly those with lower education and income, working students, self-employed, or working in the private sector. Conclusions: Employment insecurity is an important contributor to anxiety in women. The findings highlight the need to ensure job security, particularly for women working in precariat working conditions, as their work and economic stability prove to be vulnerable to external economic disturbances.

Opis: The main goal of this research work is to determine the number of new words that a primary school pupil should know/acquire during each academic year. To accomplish this, we have created two datasets. The first dataset was compiled based on the "Explanatory Vocabulary of the Uzbek Language" (EDUL). The second dataset was created from 35 primary school textbooks for grades 1-4 approved by the Ministry of Preschool and School Education of the Republic of Uzbekistan, and it was named the "Uzbek Primary School Corpus" (UPSC) by authors. Using the "Comparative Lemma Extraction Method" (CLEM) proposed by the authors of the article, a vocabulary for grades 1-4 was created, and the problem of determining the number of new words (disregarding word forms as Uzbek is a morphologically rich language) that primary school pupils should learn each academic year was solved.

Opis: Reinforcement learning has emerged as a prominent method for controlling dynamic systems in the absence of a precise mathematical model. However, its reliance on extensive interactions with the environment often leads to prolonged training periods. In this paper, we propose an alternative approach to learning control policies that focuses on learning qualitative models and uses symbolic planning to derive a qualitative plan for the control task, which is executed by an adaptive reactive controller. We conduct experiments utilizing our approach on the cart-pole problem, a standard benchmark in dynamic system control. We additionally extend this problem domain to include uneven terrains, such as driving over craters or hills, to assess the robustness of learned controllers. Our results indicate that qualitative learning offers significant advantages over reinforcement learning in terms of sample efficiency, transferability, and interpretability. We demonstrate that our proposed approach is at least two orders of magnitude more sample efficient in the cart-pole domain than the usual variants of reinforcement learning.

Opis: Fisheries bycatch is the main threat to sea turtle populations in marine habitats in the Mediterranean Sea. Bycatch in set nets accounts for 30,000 catches yearly, which combined with mortality rates of up to 82.6 %, makes it the deadliest fishing gear in the region. The Adriatic Sea is one of the most important foraging and developmental habitats for loggerhead sea turtles (Caretta caretta) in the Mediterranean. Bycatch in the Adriatic small-scale set net fishery is estimated at over 8900 individuals per year placing its mitigation among international conservation priorities. Use of light emitting diodes (LED lights) of different wavelengths as bycatch deterrents was proposed as an effective conservation tool, reducing bycatch levels by up to 93 %. In the present study we: (i) quantified the effects of net illumination on loggerhead sea turtle bycatch rates and (ii) demonstrate the importance of regional validation of conservation tools effectiveness prior to their widespread adoption. We assessed the effects of green LED lights on sea turtle bycatch rates in 390 net pairs with total length of 1278 km monitored nets. We found no significant change in sea turtle bycatch rates as a result of net illumination. A significant decrease of 35 % of primary target catch was observed in illuminated trammel nets. Possible explanations include fluctuating turbidity and an adapted LED light attachment method. Observed sea turtle bycatch rates in unilluminated nets were up to 84 times lower than in comparable gears in Northern Adriatic Sea. Understanding the drivers behind the differing bycatch rates would be necessary before conservation decisions are made. Our study showed that the net illumination is not necessarily a silver bullet for bycatch mitigation in set nets globally, and that regional testing is a key requirement before its introduction in fisheries as a conservation tool.

Opis: This opinion paper advocates for project-based learning (PBL) and teaching as a way of preserving active learning in timber engineering education. A recent example of using PBL in a timber engineering course is presented. Its strengths and associated challenges are briefly highlighted, and some suggestions are provided for the adoption of such approaches.
