Airbnb Adoption among Students: Insights from Serbia
No full textThis research was conducted to investigate the adoption rates and intents towards Airbnb platform among students in Serbia. A total of 201 students and millennials participated in the research. Findings show that only 59.6% used the services of this platform, mostly 1-2 times, predominantly for international travel. The main reasons include lower price. Respondents believed the accommodation's location and surroundings could threaten their safety, but not their hosts. Students mostly find using the platform fun and modern and are willing to recommend it further. In assessing students' future Airbnb involvement, we
investigated how location, host, and accommodation safety, along with extra costs, lower quality, and complaints, influenced participation. Unexpectedly, location insecurity positively impacts future platform usage, while poor accommodation safety
predictably diminishes it. Our findings highlight the growing popularity of Airbnb among Serbian students for international leisure travel, yet safety and privacy concerns remain. Despite this, most respondents enjoy using Airbnb and intend to continue

This paper gives a theoretical outline of the sharing economy and the Farm to Fork concept and describes their similarities. Using a case study approach, it proposes a business model to fit into strategic directions based on the abovementioned concepts
Comparative analysis of ISO 3744 and ISO 5305 standards for UAS noise measurement
Full text linkThe rapid development and expansion of Unmanned Aircraft Systems (UAS) necessitate stringent regulatory frameworks to mitigate their environmental and societal impacts, particularly noise pollution. This paper presents a comparative analysis of two key ISO standards—ISO 3744 and ISO 5305—used for measuring noise emissions from UAS. The study aims to explain the strengths, limitations, and applicability of each standard within the context of the unique acoustic challenges posed by UAS operations. ISO 3744, traditionally applied to various noise sources, provides a general framework for determining sound power levels based on sound pressure measurements. In contrast, the more recent ISO 5305 offers a specialized approach tailored specifically for UAS, taking into account the distinct acoustic profiles and operational contexts of UAS. Through a detailed examination, this paper highlights the differences in measurement methodologies and their respective capacities to address the unique noise characteristics of UAS. The findings underscore the importance of standardization in reducing noise pollution from UAS, which is crucial for minimizing their impact on both the environment and residential communities. The paper concludes with recommendations for the adoption and further refinement of these standards to better serve the needs of industry stakeholders and policymakers
Methodology of creating NFT fashion projects
