The depoliticization of protest : understanding the 2024/2025 Serbian students’ uprising
No full textThe 2024/2025 student protests in Serbia emerged in the wake of a deadly infrastructural collapse in Novi Sad, catalyzing nationwide outrage and revealing systemic failures rooted in corruption and political cronyism. the movement marked a radical redefinition of civic engagement in a post-socialist, post-ideological society. While rejecting political co-optation, ideological affiliation, and traditional opposition frameworks, students across Serbia—beginning with the Faculty of dramatic arts in Belgrade—organized peaceful, symbolically charged demonstrations that called for transparency, ethical governance, and institutional accountability. this article situates the protests within Serbia’s historical legacy of student activism while highlighting the distinctiveness of the current movement. By embracing depoliticization as both critique and strategy, the protesters complicated conventional understandings of political agency and legitimacy.their refusal to articulate a clear program or leadership structure both protected the movement from co-optation and exposed it to distortion and delegitimization. the paper critically examines the regime’s calculated response, oscillating between repression and rhetorical appropriation, and explores whether this moment signals a sustainable shift in democratic practice. Ultimately, the protests illuminate both the possibilities and limitations of moral mobilization in a compromised political environment, raising key questions about the future of civic resistance and institutional reform in Serbia
The role of digitization in brand strategy : impact on brand performance in the hobby industry
No full textThis paper examines the role of digitalization in shaping brand strategy and its impact on brand performance within the hobby industry. The theoretical framework highlighted that digitalization represents not merely a technological upgrade but a strategic transformation influencing all dimensions of brand management - from communication and customer engagement to reputation and competitive positioning. By integrating digital tools and platforms, brands can achieve higher levels of interactivity, personalization, and efficiency, thus fostering long-term consumer loyalty and improving overall market performance. The empirical research conducted among residents of South Serbia confirmed a positive correlation between brand digitalization and various dimensions of brand performance, including reputation, awareness, and competence. Although the correlations were characterized as weak to moderately strong, the statistical significance (p < 0.01) across all tested hypotheses (H1–H4) validates the positive impact of digitalization on brand performance indicators. Respondents generally perceived digital transformation as a crucial factor in enhancing brand visibility, strengthening reputation, and improving competence in the marketplace. The findings underscore that successful digital brand strategies rely on the ability to combine technological innovation with a deep understanding of consumer expectations. In the context of the hobby industry, digitalization enables companies to expand beyond local boundaries, leverage data-driven insights, and engage with consumers through social media, e-commerce platforms, and other digital channels. Consequently, digitalization not only enhances brand competitiveness but also contributes to the sustainable growth and modernization of the industry. Future research could expand the current study by including a larger and more diverse sample, as well as by employing longitudinal methods to explore how digitalization continuously influences brand performance over time. Additionally, investigating mediating factors such as consumer trust, brand authenticity, or digital engagement could provide a deeper understanding of the mechanisms through which digitalization drives brand success
Innovation as a Marketing Product in the Hotel Industry – Case Study of the Pčinja District
No full textThe aim of the chapter is to examine the impact of individual organ-
izational factors crucial for encouraging innovation in hotels. Transformational
and transactional leadership styles, organizational climate dimensions, organ-
izational learning are particularly important organizational factors influencing
the innovativeness of the organization. The authors started from the hypothesis
that the hospitality industry and the hotel industry management is still domi-
nated by conventional management styles, which lead to poor business results.
By introducing innovative management based on marketing and manage-
ment innovation, these industries can become more successful. The chapter
will present research that was conducted using appropriate questionnaires as
well as statistical processing of the obtained results The results of the research
in this chapter can be useful to decision makers for improving business in the
hospitality industry, but also to a wider interested reading audience
Звездано небо над Београдом 1862. године – симбол српске слободе
No full textРад се бави једном епизодом из обимног дела Владана Ђорђевића Успомене: културне скице из друге половине деветнаестога века, у којој је описан догађај на Чукур-чесми из 1862. године и формирање лицејске барикаде. Карактеристичан приповедачки поступак одликује одређене сегменте ове прозе на граници између документарног и уметничког, чинећи дело живим и занимљивим, а одређени пасажи – као што је представа звезданог неба, које је истовремено и приказ жељене српске слободе, али и инспирација за настанак Ђорђевићевог првог историјског романа – носе у себи вишеструку симболику и остају драгоцена сведочанства колико о догађајима, толико о стваралачким поступцима и о самом аутору
Agricultural practices as major contributors to microplastic contamination in soil
No full textWith the rising demand for higher crop yields, modern agriculture has adopted novel methodologies enabled by industrial innovations. Some practices include the use of plastic mulching and films for plant protection, temperature and weed control; plastic twine, silage, bale nets, and covers; plastic-coated fertilizers and seeds for controlled nutrient and pesticides release; and the use of plastic piping infrastructure. These methods contribute to the accumulation of secondary microplastics in agricultural soil, alongside particles from irrigation water, compost, and manure. This study aimed to identify the most prevalent polymer types in agricultural soil and investigate their links to modern horticultural practices. Samples were obtained from autochthonous soil, isolated from direct plastic debris but influenced by the processing practices of local farmers. Results show a significant amount of microplastic particles from 10 polymer types, with the majority consisting of polyamides and rubber, which are closely linked to mentioned practices and the use of agricultural vehicles.Microplastics: The Scale of the Challenge for the Agri-Food Chain, AGRIFOODPLAST International conference on micro and nano-plastics in the agri-food chain, April 8 - 9th 2025, Brussels, Belgiu
The Occurrence and Distribution of Herbicides in Soil and Irrigation Canals in a High-Input Farming Region of Serbia
No full textThis study aims to improve the understanding of, and provide insights into, the environmental fate of herbicides currently used in agriculture, which is addressed through the
analysis of the quality of canal water used for irrigation and the agricultural soil in the
immediate vicinity. The research was conducted in the main agricultural region of Serbia,
characterized by intensive crop production in conventional agriculture. Monitoring was
focused on the Danube–Tisza–Danube canal system, specifically the Bogojevo–Beˇcej section.
The presence of 41 currently used herbicides was analyzed in 520 soil samples collected from
two depths (0–30 cm and 30–60 cm), as well as in 100 canal water samples. Results showed
a high frequency of clopyralid, 2,4-D-methyl ester, terbuthylazine, fenoxaprop-ethyl, and
aclonifen, with the highest amountsbeingterbuthylazine and quizalofop-ethyl, which was
possibly a consequence of their recent application shortly before sampling. Concentrations
of herbicide residues at different depths were closely similar, without the impact of soil
mechanical and chemical characteristics on herbicide levels. In canal water characterized
as moderately salty and slightly alkaline, herbicide residues were far below the maximum
allowable concentrations, suggesting that the canal water is suitable for aquatic life, irrigation, and other uses. The findings suggest that the appropriate use of herbicides in regions
under intensive agriculture is important for reducing environmental contamination
Microplastic Uptake in Vegetables: Sources, Mechanisms, Transport and Food Safety
No full textAlthough microplastic pollution has been recognized as one of the major environmental
challenges of the 21st century, its toxicological impact on crops, especially vegetables, has
attracted limited scientific attention until recently. Vegetables represent a key component of
the human diet, making any potential contamination of great importance for food safety.
In recent years, an increasing number of studies have been conducted to investigate the
interactions between microplastics and vegetable crops. This review aims to synthesize
the current knowledge on the sources of microplastics in agroecosystems, the mechanisms
of uptake and translocation in plants, and the physiological and biochemical responses
induced by micro- and nanoplastics. This work aims to improve the scientific basis for assessing
the risk of microplastic contamination by identifying gaps in current understanding
and suggesting future research directions
Effects of High-Intensity Interval Training with Change of Direction Versus Small-Sided Games on Physical Fitness in School-Aged Children
No full textBackground: This study examined the effects of high-intensity interval training with change of direction (HIITcod) and small-sided games (SSGs) on components of physical fitness in school-aged children. The aim was to provide practical insights for optimizing exercise interventions in constrained indoor environments. Methods: A randomized controlled trial was conducted during regular physical education (PE) classes in a school’s indoor sports hall. Fifty healthy boys (mean ± SD = 12.6 ± 0.6 years) were randomly assigned to a HIITcod group (n = 25) or an SSG group (n = 25). The intervention lasted eight weeks and consisted of structured training sessions designed to progressively increase intensity and training load in a child-friendly and safe environment. Individual maximal heart rate (HRmax) was determined using the 20 m shuttle run test prior to the intervention. Heart rate monitors were worn throughout all sessions to ensure exercise intensity consistently exceeded 75% of HRmax, with real-time monitoring used to adjust effort when necessary. Physical fitness outcomes, including the shuttle run test (SRT), handgrip strength (HG), 20 m sprint, standing broad jump (SBJ), Illinois agility test, and T-test, were assessed pre- and post-intervention. Results: Both groups demonstrated significant improvements over time in the SRT, SBJ, Illinois agility test, and T-test (p 0.05). Handgrip strength increased significantly in the HIITcod group (35.03 ± 7.19 kg to 36.80 ± 6.68 kg, p = 0.001, d = 0.25) and showed a non-significant trend in the SSG group (38.28 ± 9.09 kg to 39.23 ± 9.12 kg, p = 0.056). No significant changes were observed in 20 m sprint performance. Conclusions: Based on the study results, both HIITcod and SSGs were associated with improvements in multiple components of physical fitness in school-aged boys. These findings suggest that both training modalities may be viable options for implementation during physical education classes, particularly in limited indoor settings. The observed positive changes in fitness could indicate their potential to positively impact children’s fitness in a structured and engaging manner
Yield Stability and Antioxidant Response of Wheat Under Multi-Environment Conditions: Insights from AMMI and GGE Biplot Analyses
No full textThe identification of wheat genotypes with balanced grain yield, stability, and antioxidant response to abiotic stress is crucial for creating adaptable varieties in changing climates. The research was conducted as a multi-environment trial (MET) across six environments (three localities over two seasons), and included 15 wheat genotypes (bread wheat lines, standard varieties and two spelt wheat lines). This study integrates AMMI and GGE biplot analyses with antioxidant profiling across growth stages to identify genotypes combining yield stability and stress tolerance. Lines KG-4/1, KG-11/1 and the variety Pobeda were identified as high-yielding and stable genotypes, with KG-11/1 ranked as an “ideal genotype” and KG-4/1 achieving the highest grain yield on MET level (6.48 t ha–1). Specific adaptation of genotypes KG-40/1 and Renesansa indicates their potential for targeted breeding in particular environments. Antioxidant parameters (TPC and DPPH• scavenging activity) at early growth stages were positively correlated with grain yield, indicating that they can serve as suitable biochemical markers for selecting stress-tolerant, high-yielding wheat genotypes. This comprehensive approach, which includes the analysis of grain yield stability/adaptability and antioxidant parameters, is adequate for the evaluation of promising lines that may be suitable genetic resources in climate-resilient wheat breeding programs
Aerobno fizičko vežbanje i vrednosti BMI kod učenika sa viškom kilograma
No full textSavremeni način života i nedovoljno fizičke
aktivnosti sve češće postaju problem mlađeg naraštaja.
Postavlja se pitanje na koji način vaspitno-obrazovni
sistem može uticati na rešavanje navedenog problema.
Jedan od načina jeste da se u okviru redovne nastave
uvedu dodatni časovi fizičkog vežbanja ili da se unapredi
program organizovanog fizičkog vežbanja sa
učenicima. Ova studija je izvršila analizu tri individualne
studije koje su se bavile uticajem organizovanog
aerobnog fizičkog vežbanja na vrednosti BMI i procenta
masnog tkiva učenika adolescentne dobi. U ovoj metaanalizi
standardizovane srednje razlike i relativni rizik
sa 95% intervala poverenja prikupljene su iz slučajnih
efekata. Objedinjena vrednost standardizovane razlike
aritmetičkih sredina izračunata je iz modela slučajnih
efekata i iznosi 0,32 (95% CI; -2,74; 3,38). Objedinjena
vrednost RR iz modela slučajnih efekata iznosi 0,34
(-1,15; 1,83). RR nije statistički značajno različit od jedinice
(p=0,6527). Nije uočena statistički značajna razlika
između učenika koji su pored redovne nastave imali
organizovano aerobno fizičko vežbanje radi regulisanja
viška kilograma. U ovom radu nije moguće generalizovati
zaključak zbog malog broja ispitanika
