Polyhydroxyalkanoate (PHA) has unique physicochemical and mechanical properties like conventional plastics; however, its high production cost makes it unsuitable for commercial use. Therefore, the purpose of the present study is to use low-cost and bioavailable raw materials such as agro-industrial waste of asparagus husk, as substrate for obtaining PHA by Bacillus thuringiensis. The proximal characteristics and structural carbohydrates of the waste were previously determined using HPLC. The pretreatment conditions were optimized using a Plackett-Burman design and response surface of the central compounds, evaluating temperature, %NaOH, time, % solid/liquid and solvent. Likewise, the enzymatic hydrolysates of the optimal conditions of the pretreatment were used, using an enzymatic solution with cellulase activity at 45°C at 100 rpm for 72 h. To produce PHA, a mineral-based medium, supplemented with enzymatic hydrolysate from the optimal pretreatment, was utilized. This study examined the effects of varying initial inoculum concentrations (0.25, 0.5, and 0.75 g/L) and percentages of enzymatic hydrolysate supplement (%, v/v). The process was conducted at 30°C and agitated at 125 rpm for 72 h. Maximum production of PHA was obtained with 0.138 g/L from an initial inoculum of 0.75 g/L of B. thuringiensis and a 47% supplement of the enzymatic hydrolysate. The PHA biopolymer was identified by its chemical characteristics by FTIR and correlated by HPLC with a standard. This study contributes to the use of agro-industrial waste to obtain biologically-based bioplastic through a low-cost process aligned with the circular economy strategy.

Published: July 2024

The cost of producing xanthan gum by Xanthomonas campestris is heavily impacted by the use of sugar or dextrose as a carbon source from an industrial standpoint. To address this, the researchers in this study opted to use kitchen waste, a substantial solid waste from the food industry, as a valuable source of fermentable sugars. Inedible parts of broccoli and cauliflower used as kitchen waste in this study show promising potential as an economically and ecologically sustainable material for fermenting biomolecules. This study aims to evaluate the viability of utilizing kitchen waste as a cost-effective, ecologically sustainable carbon source to produce xanthan, making use of Xanthomonas campestris NCIM 2961 in the process. Aqueous extracts of inedible parts of cauliflower and broccoli were fermented with Xanthomonas campestris NCIM 2961 at standard conditions. The fermentation parameters, including, pH, temperature, agitation, and incubation period were varied at different levels to study the effects of varying conditions on the xanthan yield and to determine the optimum levels of the fermentation parameters. After the fermentation process, the xanthan gum was separated from the broth through alcoholic precipitation and subsequent drying. The weight of the dried gum was recorded. To analyze the properties of the xanthan obtained from the alternative medium under standard conditions, it was compared with commercial food-grade xanthan using Fourier-transform infrared (FTIR) spectroscopy. The FTIR spectra of xanthan produced from the alternate medium showed a close resemblance to that of the commercial food-grade xanthan. The results obtained validate the potential of kitchen waste as a cost-effective, and eco-friendly alternative carbon source for xanthan production, thereby decreasing the cost of production and solid waste generated.

Published: July 2024

The study was focused on developing adsorbents from tofu waste (TW) for the adsorption of Pb(II) and Cu(II). FTIR analysis showed that NaOH activation of TW affected the transmittance of active sites. XRD analysis identified increasing crystallinity after NaOH treatment. SEM analysis demonstrated larger pores with higher NaOH concentrations, reducing adsorbent size. The adsorption capacity reached a maximum equilibrium of 99.86 mg/g and 87.81 mg/g for Pb(II) and Cu(II), respectively, using TW activated by 0.6 M NaOH. Both Pb(II) and Cu(II) adsorptions followed a linearized pseudo second-order kinetics model, with capacities of 100.00 mg/g and 87.719 mg/g, respectively. The Langmuir isotherm provided the best fit, yielding maximum overall adsorption capacities of 77.519 mg/g for Pb(II) and 91.743 mg/g for Cu(II) at the initial concentrations being 9.89–499.51 mg/L and 10.08–499.92 mg/L for Pb(II) and Cu(II), respectively. Brunauer–Emmett–Teller study results showed that the saturation capacities and total pore volumes were 50.505 mg/g and 49.500 L/mg, respectively, for Pb(II), and 84.388 mg/g and 237.000 L/mg, respectively, for Cu(II).

Published: July 2024

Organic food consumption can slow down environmental degradation by discouraging inputs and processes such as synthetic pesticides, fertilizers, and genetically modified organisms. A better understanding of factors that influence consumer behavior regarding the consumption of organic food in a developing nation such as Pakistan, particularly Generation Z. In this regard, this research explores the role of environmental values, environmental self-identity, and attitude towards organic food over Generation Z’s purchase intentions towards organic food. The statistical analysis of the conducted survey reveals distinctive results that provide a new direction in line with existing research. The study found that environmental values are not direct drivers of Generation Z’s attitude towards organic food. Rather, altruistic values like the wellbeing of others and society are important motivators. There are potential barriers such as affordability and availability of organic food that influence the purchase intentions of organic food. Interestingly, hedonic values, which drive joyful experiences, showed a positive impact over environmental self-identity, suggesting implications for marketers and practitioners to make Generation Z connect with nature through pleasurable activities, which eventually strengthen environmental consciousness. Finally, this research validates a positive influence of attitude towards organic food over purchase intentions, while challenges such as affordability and availability can weaken the purchase intentions among Generation Z consumers.

Understanding Regional Variations in Political Violence Victimisation in Nigeria
Authors: Alabi Tunde A ,   University of Lagos
Published: July 2024

Political violence has been part of Nigeria's history such that even to date, major political processes are still characterized by violence. However, most studies have focused on the causes of political violence, with little emphasis on the vulnerability to political violence victimisation. Using the data from Afrobarometer survey that comprised 1,568 adults, this study investigated the prevalence of political violence victimisation, associated factors and variations between the Northern and Southern regions in Nigeria. Linear regression models were fitted to understand the influence of gender, age, poverty, presence of security apparatus, political participation, party affiliation and social group membership on political violence victimisation across the two regions in Nigeria. The study found that the experience of political violence was higher in the South than in the North. Age, poverty, security presence, political participation, social group membership, and party affiliation were statistically associated with the experience of political violence. In the North, women had a higher likelihood of experiencing political violence than men (β = 0.077, p<0.05), but the reverse was the case in the South (β = -0.071, p<0.05). The frequency of participating in demonstrations or protest marches significantly increased the likelihood of political violence victimisation only in the South (β = 0.109, p<0.01), while the frequency of engaging in collective actions was positively associated with the experience of political violence only in the North (β = 0.118, p<0.05). The study submits that the two regions have notable differences that must be considered when formulating security policies in Nigeria.
The Challenges of Inclusion of the Refugees in Development Plans and National Policy in Kenya: A Case of Urban Refugees in Nairobi
Authors: Barasa Tiberius ,   Bomet University College
Published: July 2024

There is increasing global interest in promoting either stable or permanent solutions to the refugee problem in the host countries. While the Government of Kenya with the support of the United Nations High Commissioner for Refugees has implemented inclusive initiatives targeting both the refugees and the local host communities since 2021, questions have emerged whether these initiatives are bearing fruits and whether refugees’ access to crucial government services such as health, education and economic opportunities has increased. This study examines the extent of refugee integration and explores the opportunities and challenges of the inclusion of refugees into the host country’s development processes. The study adopted an explorative research design and applied a qualitative research methodology within Nairobi city to study the inclusion of urban Sudanese refugees. From a list of 200 Sudanese refugee households residing in Nairobi, a systematic sample of 20 households was selected and interviewed using a semi-structured interview schedule. The qualitative data was processed and analysed thematically. This article reveals that, while there are some opportunities towards inclusion, urban refugees have not been fully integrated with development plans. Its findings call for long-term multi-stakeholder partnerships at various levels of governance to empower actors to contribute to the integration process.

The presence of antisperm antibodies (ASAs) in infertile males is the underlying cause of ‘immune infertility’. The mechanism by which ASAs induce male infertility is not completely comprehended. Immune infertility is caused by the presence of antisperm antibodies (ASAs). While this form of infertility is very uncommon in men, it is crucial from a clinical and theoretical standpoint to comprehend the implications, targets, risk factors, and causes of male reproductive issues induced by ASAs. The main factors contributing to the cause of this condition are well recognized as anomalies in the blood-testis barrier and/or blood-epididymal barrier. Among the various parameters impacted, sperm motility is the most commonly detected. The present study elucidates the fundamental principles of ASAs, as well as their causes and risk factors.

Authors: Abduvaliev Abdulaziz
Published: July 2024

The ongoing large-scale reforms implemented in all areas of the socio-economic, environmental and political spheres of Uzbekistan are directly related to the tasks defined by Sustainable Development Goals (SDGs). One of the key directions in the development of Uzbekistan involves the formation of an innovative economy. The aim of the study discussed in the article is the assessment of the effectiveness of ongoing reforms and the results achieved in the development of an innovative economy in the country. The conducted research is of an empirical character and based on the analysis of official statistics and data provided by a variety of international organisations for the years 2013–2022. The study analyses the number of enterprises and organisations producing innovative goods and works and providing services of their own in the manufacturing industry, and the number of research specialists (also by specialisation) in Research & Development (R&D). The research shows that some positive results were achieved in this area, although a broader analysis of the innovation sphere reveals a need for more in-depth reforms. Special attention should be devoted to high technology, as the level of its development in the studied period remained the lowest.

Published: July 2024

The implementation of rooftop solar power system for SMEs is one step to provide an examplified pilot project so that the clean energy transition in the economic sector can also be realized. However, difficult operations and maintenance for rooftop solar power plant require a self-cleaning coating design to passively clean the surface of the solar cell module and hence, the performance of rooftop solar power system is maintained. In this research, the design of a rooftop solar power system utilizes global climate data, i.e., air temperature data and duration of sunlight. Long-term trends in solar radiation levels were analyzed using the Mann-Kendall test and Sen's slope analysis to assess the long-term solar energy potential. The self-cleaning layer utilized a mixture of ZnO/TiO2 (1:1) dispersed in water/ethanol (7:3). The results of implementing the solar energy system for food-based SMEs in Indramayu showed a positive response. Solar energy supply from rooftop solar power system with the application of ZnO/TiO2 self-cleaning coating can save energy usage by up to 30% of the monthly electricity costs charged for MSME operations and domestic needs. The ZnO/TiO2 self-cleaning layer is found to be able to maintain rooftop solar power system performance of up to 85% during 9 months of observation.

Authors: Nakam Ogly , Vladimirovna-Pak Irina
Published: July 2024

The purpose of the current work was to determine the microbial composition of litter generated during the industrial rearing of broiler chickens. This is necessary in order to achieve an understanding of the influence of various microorganisms on the processing of waste products for absorption into the soil without harming and polluting the environment, for example, with bound phytate ions. The object of the study was litter sampled from under broiler chickens of different ages and parent flocks. During the study, the following groups of microorganisms were identified: peptococci (family Peptococcaceae); actinomycetes (except for the family Pasteurellaceae) from the order Actinomycetales; actinobacillus (family Pasteurellaceae); lactobacilli and enterococci (genera Lactobacillus and Enterococcus, respectively); bacteroides (phylum Bacteroidetes); ruminococci (genus Ruminococcus); eubacteria (family Eubacteriaceae) and enterobacteria (family Enterobacteriaceae). Quantitative indicators of colonies of various taxonomic groups were determined, and it was shown that these indicators changed with increasing period of litter use. Furthermore, the study revealed that the microbial composition of the litter changed over time. As the litter age increased, there was an increase in the abundance of certain bacteria, such as Peptococci and Actinobacillus, which are known to be involved in the decomposition of organic material.

Published: July 2024

The significance of employing Plant Growth Promoting (PGP) microorganisms holds immense value in the cultivation of medicinal plants, where the attainment of high-quality plant biomass is indispensable. Therefore, it becomes imperative to isolate and identify a diverse array of microorganisms from the rhizosphere of various plants and assess their efficacy in enhancing the growth of medicinal plants. The primary aim of this research was to isolate and characterize bacteria belonging to the Bacillus, Streptomyces, and Azotobacter genera from the rhizosphere of nettle (Urtica dioica L.). Additionally, the study explored the influence of the bacterial isolates on the germination of oregano (Origanum vulgare L.) and marjoram (Origanum majorana L.) seeds. Isolation, physiological characterization (the growth of isolates at different temperatures, levels of acidity and concentrations of NaCl, and resistance of isolates to Cd and Pb), biochemical characterization (the production of lipase, amylase, pectinase, and cellulase), and PGP characterization of isolates were performed. The impact of isolates on seed germination was monitored under controlled conditions. The count of sprouted seeds was assessed at 7-and 10-day intervals. The results of this study reveal that the isolated rhizospheric bacteria of nettle have multiple physiological, biochemical and PGP properties. All isolates showed good PGP potential, but the isolates Azotobacter A1 and Streptomyces Ac1 stood out. The applied isolates had a positive effect on the seed germination of oregano and marjoram, the best effect being exhibited by Bacillus B2 and Azotobacter A1 on the seed germination of oregano and by Bacillus B1 and Streptomyces Ac1 on that of marjoram.

Is pain representational?
Authors: Aydede Murat
Published: July 2024

Representationalism in philosophy of perception has become more or less the dominant view. There are various versions of it not all of which are motivated by the same set of concerns. In this paper, I will focus on what has come to be known as strong representationalism. This view has reductive and non-reductive versions, which are usually paired with realist and irrealist versions respectively. Here, first, I will develop a simple, largely empirical, argument against realist reductive version. Later, rather more briefly, I will extend the argument to cover irrealist representationalism.
Embodied pain, chronic pain, and Grahek's legacy
Authors: Milojević Miljana , Subotić Vanja
Published: July 2024

This paper argues in favour of the embodied approach to pain. We start by asserting that an appropriate philosophical treatment of pain must be empirically informed, rather than relying solely on the conceptual analysis typical of what we call "orthodox views of pain. " We then examine contemporary empirically informed views, specifically enactivism and eliminativism, by testing them against the aberrant pain phenomenon, namely chronic pain. This method of using fringe cases and aberrations to test philosophical theories of pain follows the approach of Grahek (2007), who criticized subjectivism and objectivism based on their failure to account for pain asymbolia and congenital analgesia. We contend that the embodied approach holds an advantage over eliminativism and enactivism as it integrates the subjective, phenomenal aspect of pain-understood as a form of perceptual expectation-with the objective behavioural and neurological aspects by proposing a specific top-down connectionist cognitive architecture. We test two predictions of this approach: (1) that pain is multimodal and cognitively penetrable, and (2) that aberrant forms of pain, such as chronic pain, can be modulated not only by manipulating its immediate neurological source but also by altering the multimodal body image through virtual reality (VR) technology and our cognitive states, primarily our expectations about the environment.
New industrial policy of Serbia: Possibilities and limitations
Authors: Lutovac-Đaković Milena
Published: July 2024

Numerous factors have contributed to the growing interest in industrial policy. In recent years, industrial policy has been increasingly used as a response to crises. Developed countries of the world strongly intervened in their industries after the global economic crisis in 2008, and it has become much more intense after the crisis caused by the COVID-19 pandemic (with the goal of restarting economic growth). Finally, industrial policy has become a significant instrument for the industrial transition to a green and digital economy. The goal of the new industrial policy of Serbia is to promote structural changes in the industry in favor of the production of goods and services with greater added value, modernization and increasing the role of industry. New industrial policy has become more complex with new goals beyond conventional industrial development and structural changes, such as integration and upgrading into global value chains (GVCs), developing a knowledge-based economy, building sectors related to sustainable development goals and competitive positioning for a new industrial revolution [12, p. 199]. The paper analyzes the effects of state aid in 72 successfully implemented investment projects to attract investment in Serbian industry in the period from 2006 to 2016. Four bootstrap confidence intervals were used: bootstrap-t interval, percentile interval, BCa interval, and ABC interval. The constructed intervals give us information on the assessment of the average number of newly created jobs and average investments in realized projects in the period from 2006 to 2016.
The role and importance of digital marketing techniques in creating user experience and customer engagement in the process of joint creation (co-creation)
Authors: Trajković Slaviša , Milosavljević Srđan , Aleksić Ivana
Published: July 2024

Modern business conditions, characterized by the accelerated development of technique and technology, resulted from the globalization process, have completely changed the environment in which companies operate. The era of the Internet is characterized, on the one hand, by new business models, which have conditioned the digitization of business and especially marketing, and, on the other hand, consumers who are "loud and active", save their time, want quick feedback, individual offers and, consequently, participation in product design or service. In this regard, the subject of research in this paper involves correlational tests, on the one hand of respondents' attitudes towards digital marketing techniques and, on the other, their willingness to accept promotional content on the Internet, make a purchase decision, access electronic transactions and participate in interaction with company. The aim of the research is to analyze the contribution of digital marketing techniques in the creation of user experience and customer engagement in the process of joint creation (co-creation). A total of 335 respondents participated in the research conducted through a survey method. The results of the research show that the marketing content that companies place through digital marketing techniques influences consumers' decision to buy a certain product, while the quality and the way the marketing content is placed affect their loyalty. Also, user experience and customers' willingness to participate in different segments of co-creation are conditioned by the application of the mentioned techniques, as well as by interaction with the company through which customers can share their opinion and creativity, but also express their needs and wishes regarding the characteristics of products and services, which represents a way of personalizing the company's offer. The potential for business improvement through the application of digital marketing techniques is great, that's why investments in the aforementioned techniques represent an investment, not an expense.

Published: July 2024

Iron deficiency is one of the most common nutritional deficiencies that can lead to anemia. Children and adolescents, women in the reproductive period, pregnant women, regular blood donors, vegetarians and vegans, and people with gastrointestinal disorders have an increased risk of developing iron deficiency. For these population groups, regular monitoring of iron status and, if necessary, additional iron supplementation is important. The aim of the study was to make an overview of available iron-containing dietary products (food supplements and foods for special medical purposes) in the Serbian market. 44 iron-containing dietary products, 33 food supplements, and 11 foods for special medical purposes were selected for analysis. The composition, chemical sources, and content of iron and other vitamins/minerals, as well as the recommended dosage and dosage form, were evaluated based on the information from product labels. Capsules are the most predominant dosage form (41%). Iron(III)-pyrophosphate (34%) and iron(II)-bisglycinate (25%) are the most common chemical sources of iron. Most products (75%) provided between 50 and 150% nutritional reference value (NRV), while 91% of foods for special medical purposes contained more than 150% of the NRV for iron. Most of the analyzed products were multicomponent (91%), indicating the importance of other micronutrients in preventing anemia and improving iron status. Among them, vitamin C (71%), folic acid (61%), and vitamin B12 (59%) were predominant. Adequate selection of the type, as well as counseling on proper consumption of iron-containing products, is important to ensure the rational and safe use of these products.

In managing Type 2 diabetes, inhibiting enzymes present in the initial stages of carbohydrate digestion, a-amylase, and a-glucosidase, could be important. Conventional inhibitors such as acarbose exhibit adverse effects, necessitating the exploration of natural products for alternative solutions. Moderate red wine consumption, rich in polyphenols, offers a biochemically supported strategy by impeding a-amylase and a-glucosidase activity. Thus, the objective of this study was to assess the in vitro a-amylase and a-glucosidase inhibitory activities of 14 Merlot wines (5 Serbian and 9 European), with a focus on elucidating the correlation between their inhibitory potency and polyphenolic profile. All samples demonstrated an inhibitory effect on both enzymes: a-amylase and a-glucosidase activities (113.6-349.5 mg equivalent acarbose/mL of wine and 1.09-12.34 mg equivalent acarbose/mL of wine, respectively), still no discernible correlation was observed between the level of inhibition and the categorization of wines based on their respective regions. The total content of polyphenols, flavonoids, tannins, and monomeric anthocyanins in examined wines showed that overall concentrations were lower in Serbian and Macedonian than in Italian and French wines. Dominant phenolic acid in all Merlot samples was gallic (10.7-134.0 mg/L), catechin was the most prevalent flavonoid (9.1-43.4 mg/L), stilbene resveratrol was also present in all samples (0.34-4.67 mg/L), while malvidin-3-O-glucoside was the most abundant anthocyanin (2.6-56.5 mg/L). Examined wines showed some specificity regarding the polyphenolic profile and could be, to some extent, differentiated primarily based on the quantitative content of polyphenols. A moderate correlation was evident between a-amylase inhibitory activity and the content of total anthocyanins and malvidin-3-O-glucoside, while notable dependence was observed between a-glucosidase inhibitory activity and the contents of total polyphenols and tannins as well as gallic acid and catechin.

Published: July 2024

Buccal fat pad (BFP) is used in oral and maxillofacial surgery for closing oroantral communications (OAC), closing larger oroantral and oronasal defects, repairing congenital clefts, covering bone grafts, temporomandibular joint surgery and in aesthetic surgery. In daily oral surgery practice, the use of a BFP to close the OAC is indicated when there is a fistula on the mucosa of the vestibule, wide communication in the distal parts of the edentulous alveolar ridge and wide OAC in the region of the third molar and in cases of prominent coronoid process of the lower jaw.

Objective: The aim of this study was to evaluate the relationship between the immunohistochemical score of cell proliferation index Ki-67 and steroid receptors in patients with a pathohistological diagnosis of breast cancer. The impact of neoadjuvant therapy on biological markers in breast cancer remains controversial. Methods: All patients with invasive breast cancer, as the primary and only malignancy, who underwent surgical and neoadjuvant therapy at the Institute of Oncology and Radiology of the Republic of Serbia (IORS) between 2017 and 2019 were included in the retrospective study. The expression level of Ki-67 and steroid receptors was detected by immunohistochemical analysis. Data were collected in an Excel database and analyzed in the statistical software SPSS program version 25. For statistical data processing Chi-squared test, KruskalWallis test, and Mann-Whitney U test were used. For all statistical analyses, a p <0.05 was considered statistically significant and a p≤0.001 was considered highly statistically significant. Results: The study included 190 patients with invasive breast cancer. The mean age of all patients at diagnosis was 57.2 ± 11.8 years. Among the patients, 64.2% are postmenopausal, 33.7% perimenopausal and 2.1% menopausal. There is a significant inverse correlation between the value of Ki-67 and the expression of steroid receptors. Conclusion: Ki-67 is an important biomarker in clinical practice for determining prognosis, residual risk, and response, and evaluating the effectiveness of neoadjuvant therapy. The results of our study revealed a correlation between high Ki-67 cell proliferative index values and lower steroid receptor expression values.
Artificial intelligence and national security strategy development: Challenges and perspectives
Authors: Pavić Aleksandar , Beriša Hatidža
Published: July 2024

As a rule, the directions of development of the national security strategy are always aligned with vital national interests and modern achievements of society, which are imbued with modern challenges, risks and threats and available instruments of power. Monitoring global trends and the use of an adequate methodological approach enables the strategy to reflect a clear definition of national interests, ways of achieving them and the state's ability to achieve those interests using instruments of national power. Artificial intelligence through various forms of manifestation will significantly influence the development of future society. The implementation methodology will depend primarily on the needs and capabilities of the state. The goal of this work is to bring artificial intelligence closer to the professional public and to somehow place it in the focus of future considerations in the field of security and defense. Technology, which every day is becoming more and more present in all spheres of life, must find its role and place in strategic and doctrinal documents related to the defense of the state. Artificial intelligence must be integrated and operationalized as one of the starting points for creating a modern national security strategy, which is also the thesis of this expert work. The thesis clearly implies that the future national security strategy cannot be conceived without the concept of using artificial intelligence. The theoretical foundation of artificial intelligence is imbued in various scientific fields that primarily deal with automation and autonomous use of systems. Practical application found its basis in the gradual but comprehensive digitization of all spheres of life and society as a whole. From the point of view of national security, it is especially important to consider the impact in the development of autonomous weapon systems, the perspective of their use and the way they will shape modern armed conflicts.
Structural limitations of the new social movements actions
Authors: Korolija Aleksandar
Published: July 2024

The paper conducts conceptual research based on Gramsci's theory of hegemony. The structural limitations of New Social Movements and the lack of transformative strategies are analyzed analytically, in order to answer the research question why social movements failed to achieve changes in the economic and political system through transformative action. After a brief presentation of Gramsci's meaning of hegemony, we move on to the definition of the concept of counter-hegemony, which Gramsci left with an ambiguous meaning. Analysis then moves on to definitions of New Social Movements and their strategies, which are then linked to the concept of counter-hegemony. On this theoretical basis, it is examined whether the resistance practices used by the New Social Movements can bear the name of counter-hegemony. Next step of the analysis moves on to the question of Social Non-Movements and their strategies in order to examine the action of a new type of social movements that is more closely related to the countries of the Middle East. Analysing the concept and strategies of Social Non-Movements, it is noted that these are social movements that represent a specific Middle Eastern society, however, they are similar to social movements of Western society in that they do not try to bring about deeper transformations of the political and economic structure. Since the New Social Movements are characterized by a shift from the area of production to the area of consumption, it is concluded that the main structural limitations of resistance/counter-hegemonic strategies are based on this transition. By abandoning the question of the organization of the economic system of production, as well as rejecting political society in favour of civil society, these movements remain within the dominant policy paradigm. Fragmentation/atomization with emphasized problems of identity recognition and insistence on the politics of differences, along with the rejection of political organizations and leadership on a conceptual level, rejects the establishment of a new hegemony and thus defines the action of social movements as anti-hegemonic. Therefore, at the very conceptual level, it can be observed that New Social Movements as well as Social Non-Movements do not have deeper intentions to make their strategies counter-hegemonic and to establish a new hegemonic project. On this basis, it is concluded that social movements failed to bring about deeper structural changes in politics and economy because they remained within the framework of the existing hegemonic project.
Creating the "Serbian world": Qualitative content analysis of public statements regarding the concept and defining its dimensions
Authors: Ljubomirović Aleksandar
Published: July 2024

This article sets out to present selected outcomes of the author's research on the dimensions of the "Serbian world" concept. Although the term has indeed become quite popular in the public discourse, the concept per se has not been part of academic discussions. Therefore, this paper sets out to analyse the content of the afore-mentioned concept and introduce it into the scientific framework. The methodology used in this paper includes a qualitative content analysis of the public statements regarding the Serbian world concept, which are available and published, first and foremost, in domestic media outlets. At the same time, the analysis of the concept is limited to observing its various dimensions, using the statements of Serbian officials as examples of discursive shaping and construction of each of the separate dimensions. Based on the carried-out research, the concept is founded on the idea of creating a supranational Serbian civilization based on ancient models. This community would unite all Serbs, the Serbian diaspora, but also all those people simply learning Serbian or identifying with its values, and declaring an attachment to Serbian culture. Besides its territorial dimension, which has so far prevailed in public discourse especially among its opponents, the Serbian world also resides on national, psychosocial and cultural components, while the main ethnos in the concept is certainly the Serbian nation, around which other ethnic groups should gather. Moreover, nationality-related, psychosocial and cultural dimensions are also supposed to be important aspects according to the discourse participants. The last component would be the Orthodox religion which is supposed to be one of the main pillars and an important co-constituent of the Serbian world *
