Wpływ opinii internetowych na wybory konsumenckie
No full textW warunkach rosnącej popularności zakupów dokonywanych za pośrednictwem Internetu, opinie użytkowników dostępne online odgrywają istotną rolę w procesie podejmowania decyzji zakupowych. Możliwość szybkiego dostępu do recenzji produktów oraz danych rynkowych sprzyja bardziej świadomemu wyborowi oferty. Opinie innych użytkowników – zarówno pozytywne, jak i negatywne – mają istotny wpływ na sposób postrzegania marek oraz na poziom zaufania wobec nich. Wyniki badania wskazały, że chociaż chętnie korzystamy z recenzji, rzadko sami je wystawiamy – tylko 3% ankietowanych robi to systematycznie. Komentarze odnoszące się do jakości, trwałości produktu czy jakości obsługi klienta stanowią ważny punkt odniesienia w procesie zakupowym. W kontekście rosnącej liczby sponsorowanych treści, kluczowe staje się krytyczne podejście do napotykanych informacji. Umiejętność rozróżnienia autentycznych opinii od tych, które powstały na zlecenie producentów, ma znaczący wpływ na jakość podejmowanych decyzji. Celem artykułu jest omówienie wpływu opinii internetowych na decyzje zakupowe konsumentów. Badanie zostało przeprowadzone w kwietniu 2025 roku, a głównym narzędziem badawczym był kwestionariusz ankiety sporządzony oraz udostępniony za pośrednictwem formularza Google. Zebrane dane poddano analizie z wykorzystaniem programów Statistica oraz Microsoft Excel. W celu zbadania zależności między zmiennymi wykorzystano tabele wielodzielcze. Do porównania wybranych grup zastosowano nieparametryczny test U Manna–Whitneya. Na jego podstawie oceniono istotność różnic występujących w opiniach osób różnej płci
The Linguistic Image of Fish in Spanish, Arabic, and Japanese: A Comparative Study
No full textThis paper explores the linguistic and cultural significance of the term 'fish' across three languages: Spanish, Arabic, and Japanese. By analysing phraseological units (PhUs), including collocations and proverbs, the study integrates cultural linguistics and phraseology to show how fish-related PhUs reflect broader cultural values and beliefs, as well as the historical, religious, and social contexts. The research draws from a variety of dictionaries and linguistic sources to examine these representations, revealing how the symbolism of fish permeates worldviews in maritime cultures
Digital drug trading ecologies in context: Technological, geographic, and linguistic variation across darknet platforms
No full textBackground Previous research on darknet drug markets has primarily concentrated on large, English-language cryptomarkets, often overlooking regionally oriented platforms that operate in national languages. This study adopts a comparative, exploratory approach to examine how drug trade practices vary across linguistic, geographic, and technological contexts. We introduce the concept of “drug trading ecologies” to describe how platform features, communication norms, and localized settings together shape distinct trading environments. Methods Using a mixed-methods approach, we analyzed web-crawled data from three Tor-based platforms: Tsatti (Finnish-language chat), Cebulka (Polish-language forum), and Nemesis (English-language cryptomarket). Data were collected through customized web scraping and analyzed using statistical tools and qualitative content coding to examine platform-specific patterns. Our comparative approach highlights structural and localization-specific variations without attempting exhaustive conceptual definitions. Results Each platform displayed a distinct configuration shaped by its technical affordances and localization-specific user practices. Tsatti supported fast, hyperlocal, and highly anonymized exchanges with minimal user identity or community features. Cebulka enabled semi-public vendor-buyer interactions, trust-building through discourse, and diverse product bundling. Nemesis functioned as a transnational, professionalized cryptomarket with standardized listings, formalized trust mechanisms, and branding strategies. Conclusions Rather than attributing differences solely to local, transnational, or design factors in isolation, we argue that darknet drug trading ecologies emerge from the intersection of platform architecture, localization (geographic scope), and language. Our findings underscore the importance of considering these factors when conducting digital ethnography in illicit economies and providing concrete entry points for tailoring harm reduction interventions responsive to the diverse realities of online drug trading.This research is supported by the Polish National Science Centre, Poland (Narodowe Centrum Nauki), grant: 2021/43/B/HS6/00710.

Cultural landscaps of the selected islands of the Baltic sea in terms of the cultural tourism develoment
No full textTurystyka kulturowa uważana jest za jedną z najbardziej dynamicznie rozwijających się form współczesnej turystyki. O ile walory wypoczynkowe wydają się w swej różnorodności dość ograniczone (i sprowadzają się zwykle do tych cech środowiska, które pozwalają na bierny lub aktywny wypoczynek, względnie poprawę zdrowia), to kultura w swej niebywałej złożoności oferuje turystom ogromną liczbę wytworów czy też praktyk, które mogą wzbudzać zainteresowanie i stać się przez to atrakcjami turystycznymi. Kultura odzwierciedla się również w krajobrazach kulturowych, te zaś wchodzą w ścisłe relacje z turystyką. Celem artykułu jest prezentacja potencjału turystycznego krajobrazów kulturowych wybranych wysp Bałtyku, opisanych jako źródło wiedzy o zamieszkujących je społecznościach, jak i w kontekście rozwoju określonych form turystyki kulturowej.Cultural tourism is considered to be one of the most dynamic developing forms of contemporary tourism. In so far as leisure natural features seem to be limited in terms of their diversity (and they come down to these features of natural environment, which let tourists rest passively or actively or enhance their mental or physical health), human culture – extremely rich, multidimensional and complex – offers enormous volume of its products and cultural practices, which might be interesting to tourists. Human culture reflects itself in cultural landscapes, and they make strict relations with tourism. The paper’s aim is to describe tourism potential of cultural landscapes of the selected Baltic islands, presented as a source of knowledge on communities settled there, and with reference to de-velopment of particular forms of cultural tourism
Next Generation Squad Weapon – A revolution in combat weapons for U.S. Army infantry?
No full textIn recent years, there has been a noticeable increase in military expenditure of the People’s Republic of China (PRC) and the Russian Federation. This trend has raised concerns especially in the United States, since the PRC’s authorities want it to emerge as a global superpower. The importance of this country in international relations is also increasing due to a decline in Russia’s capabilities, which results from the ongoing war in Ukraine (however, it should be noted that Russia still remains an influential actor). Those ambitious plans have prompted a response from Washington, accelerating the strategic competition across various domains, including the military one. In this field, it is manifested in technological advancements, which refers not only to highly complex weapon systems, such as aircraft or vessels, but also to individual equipment. Among many components of the American response to Chinese and Russian activities, the Next Generation Squad Weapon (NGSW) program is worth mentioning. This is because its purpose is to replace the AR-15 family of firearms, which have remained in service within the U.S. Army for over 60 years, with a completely new armament system. However, it should be noted that its implementation will initially be limited to units designated for direct combat operations (referred to as close combat units). Similarly, soldiers who have operated the M249 light machine gun so far are going to be armed with a next-generation weapon system. Notably, the program is not limited to developing firearms. Particularly, its other components consist of an advanced telescopic sight and a new type of ammunition. Owing to the fact that these weapon systems are currently being introduced into service, it is worth considering if their implementation will represent a breakthrough for the U.S. Army infantry. If so, what consequences might emerge from this change? In order to answer this question, particular elements of the program are going to be examined, after a brief overview of its history. The analysis is going to be based on articles, official statements and other materials published by the U.S. Army and the manufacturers of the new weapon systems
The role of the Notch signaling pathway in rhabdomyosarcomas
No full textRhabdomyosarcoma (RMS) is a pediatric soft tissue cancer with poor prognosis in cases of metastasis. Different signal transduction pathways have been studied in RMS cells as to shed some light into the tumorigenesis and metastasis mechanisms of this cancer in the search for new diagnostic and therapeutic strategies. The Notch pathway, which regulates cell survival, is widely studied in different cancers, including sarcomas and its activation has been known to induce cell motility. To this end, the present review explores the role of the Notch signaling pathway in the progression of RMS and in potential therapeutic strategies

Diet-induced obesity influences atherogenic indices and increases risk of cardiovascular disease in male Wistar rats
No full textBackground: Relationship between obesity and cardiovascular diseases is complex. This study aimed to evaluate the correlation between diet-induced obesity and atherogenic indices.
Material and methods: Two groups of 8-weeks old male Wistar rats (170 ± 15 g) were fed with normal chow and high fat diet (HFD) respectively ad libitum for 10 weeks. Body mass index (BMI), adiposity index, serum lipid profile and atherogenic indices were measured. Associations between lipidemic indices, BMI and atherogenic indices were evaluated.
Results: The group fed with HFD only had significantly increased BMI (0.7630 ± 0.083, p = 0.0065). Serum TG (p 0.0.71 g/cm2). There was a significant positive linear association of BMI with most of the atherogenic indices investigated: coronary risk ratio (CRR) (OR 48; 95% CI 4.993, 461.50; p < 0.001), atherogenic index (AI) (OR 1.0; 95% CI = 2.56, 229.57; p < 0.001) and atherogenic coefficient (AC) (OR 65.0; 95% CI 6.68, 648.26; p < 0.001).
Conclusions: Consumption of HFD induces hyperlipidemia and increase the risk of coronary artery diseases by increasing the atherogenic indices
