OneTrack - An End2End approach to enhance MOT with Transformers
Authors: Araujo Luiz , Figueiredo Carlos
Published: October 2024

This paper introduces OneTrack, an innovative end-to-end transformer-based model for Multiple Object Tracking (MOT), focusing on enhancing efficiency without significantly compromising accuracy. Addressing the challenges inherent in MOT, such as occlusions, varied object sizes, and motion prediction, OneTrack leverages the power of vision transformers and attention layers, optimizing them for real-time applications. Utilizing a unique Object Sequence Patch Input and a Vision Transformer Encoder, the model simplifies the standard transformer approach by employing only the encoder component, significantly reducing computational costs. This approach is validated using the MOT17 dataset, a benchmark in the field, ensuring a comprehensive evaluation against established metrics like MOTA, HOTA, and IDF1. The experimental results demonstrate OneTrack's capability to outperform other transformer-based models in inference speed, with a marginal trade-off in accuracy metrics. The model's inherent design limitations, such as a maximum of 100 objects per window, are adjustable to suit specific applications, offering flexibility in various scenarios. The conclusion highlights the model's potential as a lightweight solution for MOT tasks, suggesting future work directions that include exploring alternative data representations and encoders, and developing a dedicated loss function to further enhance detection and tracking capabilities. OneTrack presents a promising step towards efficient and effective MOT solutions, catering to the demands of real-time applications.

Authors: Schneider dos Santos Everton , Machado dos Santos Matheus , Castro Márcio , Tyska Carvalho Jonata
Published: October 2024

Fraudulent companies form illegal agreements, like collusion and cartels, to circumvent the impartiality and competitiveness of the public procurement auctions. These types of fraud can cause significant financial losses and erode trust in the public sector. Therefore, building reliable methods for early detection of frauds is a priority for public organizations. This study uses an enriched version of the “Operation Car Wash” dataset to evaluate the collusion detection capabilities of different machine learning algorithms. Using cross-validation techniques, the methodology proposed in our work was able to improve the collusion detection rate of the learning models used in this work, outperforming the results of other works found in the literature.

Richard Nicolas von Coudenhove-Kalergi’s Pan-Europe”: the relevance of a manifesto from a hundred years ago
Authors: Cojocaru Gheorghe
Published: October 2024

This material evokes the main ideas of the „Pan-Europe” manifesto, launched in 1923 by Count Ruchard Nicolas von Coudenhove-Kalergi, in the context in which Europe was divided between Russian Bolshevism, Germany’s dissatisfaction with the Versailles order and new technologies which Western societies were beginning to enjoy. Through his project of pan-European unification, Kalergi aimed to protect from further humanitarian disasters. In order not to force integration processes, he spoke in favor of identifying an optimal relationship between national policies and integration policy at the European scale. Imagining the frontiers of Pan-Europe, his creed was: „Rather than a victorious war, some bad frontiers”. The Romanian Dniester, in Kalergi’s conception, fixed a hundred years ago the Eastern border of Pan-Europe as a space of freedom and democracy.
Exploring the concept of language awareness in the Curriculum in English in Norway: discussing the potential of picture books for enhancing young learners’ language awareness
Authors: Mellegård Ingebjørg
Published: October 2024

This exploratory article provides an introduction to language awareness and discusses the potential of picture books as a textual resource to enhance young learners’ understanding of how language works. The construct of language awareness is investigated and discussed according to its three main components: the cognitive, affective and social dimensions. It is argued that language awareness represents a holistic approach to language teaching and needs to be naturally integrated into teachers’ pedagogical practices. Furthermore, the article looks at how the last revision of the English subject curriculum in Norway, introduced in 2020, involves language awareness and how this concept is communicated. The curriculum seems to reflect a language learning theory that correlates strongly with the theoretical basis for a language awareness approach. It is noted that the teacher’s knowledge of language and engagement with language are crucial factors for facilitating discovery-oriented learning activities, which are considered critical to scaffolding learners’ engagement with language. Picture books are considered a valuable resource in this respect; the qualities that make this literary genre such a useful resource are outlined and reflected on. The article ends by presenting some selected picture books and exploring their potential for using them in the English classroom to promote learners’ engagement with language and hence, contribute to cultivating their language awareness.
Folklores as Basis for Philosophical Instructions at the Pre-tertiary Level in Nigerian Schools
Authors: Okoye Uche Miriam , Nnaemeka Chukwuma Joseph
Published: October 2024

Philosophy for children is a philosophy applied to education for the purpose of producing students with improved proficiency in reasoning and judgment. Recently, African philosophers have begun to reflect on the pedagogical framework for engaging pre-tertiary students in philosophical discussions. This is necessary, considering the import of philosophy as a discipline in the moral development of students. This paper is a reflection on how folklores could be used as philosophical resource in schools to encourage moral and critical thinking in school children. The summation of the paper is that the inclusion of African oral ethics in the Nigerian pre-tertiary curricula will help cultivate and refine the mind of students to engage in moral reflection and analyze moral problems of human life. This will ultimately help instill moral character in them and also aid their participation in African culture. The philosophical methods of exposition and critical analysis are used.
Being-with-Others: Metaphysical Pedagogy for Social Peace
Authors: Olatunji Oni Michael
Published: October 2024

The prevalence of violent conflicts in most African States, as a result of rigid understanding of reality, threatens human existence and inhibits social transformation. In the face of so much failure in political and religious interventions, education remains a potent tool for re-engineering and moulding people's minds. It is the argument of this paper that in order to ensure a peacefull and orderly society, freedom of 'others' is necessary. It is indeed a time-tested view that acceptance and respect for individuals are ways to establish peace in any society. While this cannot be denied, metaphysics is considered here as socially relevant, and as such, can be taken as relevant for addressing some of the pressing problems that confront the world today. The theoretical basis upon which this paper makes statements is the Transformative Leaming Model - a model that essentially alters individual frame of reference by considering assumptions and beliefs, so as to construct new ways of defining the world.

Beyond traditional consumer research - current adoption and next steps for neuromarketing
Authors: Puprediwar Pratik B , TAPAS Dr. POORNIMA
Published: October 2024

Purpose. Neuroscience used for conducting market research is called Neuromarketing. Though the effectiveness of Neuromarketing over traditional research has been proven, its adoption is very limited. The automotive sector is one of the biggest industries worldwide and due to lack of detailed research on the adoption of Neuromarketing in the Automotive space, authors have tried to bridge this gap. They have identified the current adoption of Neuromarketing and have suggested solutions to overcome barriers. This research will help Automotive brands, market research companies and Neuro experts to come up with relevant solutions to increase the usage of Neuromarketing
Design. The authors first reviewed any available literature related to the Automotive landscape. Then, in-depth discussions with Automotive players were conducted in order to clarify the Neuromarketing adoption in the current scenario. Finally, Neuro experts, viz. neuroscientists and research companies, were consulted
for possible future solutions
Findings. Literature reviews and discussions with Automotive companies revealed that Neuromarketing adoption is limited as compared to traditional market research methods. Though the majority are aware of Neuromarketing, limited companies have used it. It is mostly undertaken in advertisement and product
testing, primarily using EEG and Eye tracking. Neuromarketing is perceived as being expensive and difficult to understand and having ethical concerns. It is also believed that Neuromarketing does not answer the ‘why’ behind the participants’ responses.
The paper also validated Simon’s Bounded Rationality Theory where automotive organizations used conformity instead of maximum value in adoption of neuromarketing. Expert discussions clarified that most of the Neuromarketing limitations like ethics, cost, lower sample, lab setup, etc. mentioned by
Automotive players can be overcome. Hence the next step is to take this science to maximum automotive players and make them aware of the development, conduct pilot studies, remove their inhibitions about Neuromarketing and complement it with traditional research methods.

Linear Regression-Based Traffic Flow Simulation: Vehicle Density and Speed Analysis on Buah Batu Road
Authors: Ichwanul Ichsan Adam , Harry Gunawan Putu
Published: October 2024

Traffic congestion has become an increasingly severe problem in many major cities around the world, including in the city of Bandung. Population growth and increased vehicle use exacerbate congestion. Jalan Buah Batu, one of the main roads in the city of Bandung, often experiences congestion due to high density. This study explains the traffic flow simulation using the Lighthill-Whitham-Richards (LWR) model with a speed-density function obtained from observation data on Jalan Buah Batu, Bandung. The data included the relationship between vehicle density and speed which was then analyzed using the linear regression method. The approximation of the velocity-density function obtained from linear regression is v(ρ)= -6.904+4.302. Traffic flow simulations were carried out with a road length of 60 meters, a total time of 5 minutes, and high resolution with 300 grid points. At the beginning of the simulation, a peak density of 0.70 occurred in a 15-25 meter road segment. Over time, the peak density shifted and decreased: 0.65 at 20-30 meters at 1.25 minutes, 0.60 at 25-35 meters at 2.5 minutes, and 0.50 at 30-50 meters at the end of the simulation (5 minutes). These results show the movement of vehicles that reduce congestion and improve the smooth flow of traffic. In conclusion, linear regression is effective in determining the velocity-density function.
Understanding the production and reduction of barium sulfate crystals through the use of additives and a controlled stirring rate
Authors: Karaman N. , Maulida R. S. , Fariana N. , Bayuseno A. P. , Suprianti Lilik
Published: October 2024

Barium sulfate crystals are minerals responsible for scaling in piping systems. Controlling the growth of these crystals can use additives (FeCl2 and SrCl2) and varying agitation speeds. The research was to optimize the impact of additives and agitation speed on the results of crystal form using RSM through Minitab 19 with Box-Behnken Design. The optimum conditions using additive FeCl2 at a concentration of 25 ppm, a stirring speed of 120 rpm for 30 minutes, and a coefficient of determination (R2) of 90.995 provided  0.4485 gr of barium sulfate crystals. The optimum conditions, however, used SrCl2 additives at a concentration of 20.2049 ppm and a stirring speed of 459.394 rpm for 30 minutes, yielding 0.4345 g of barium sulfates with a coefficient of determination (R2) of  91.41%. The results of crystallizing barium sulfate without additives appear to be superior to those obtained with additives in terms of production. In contrast, additives of FeCl2 and SrCl2 can inhibit barium sulfate formation, resulting in a reduction in crystal mass

Covid-19 and Its Impact in Dental Health and Profession: A Review
Authors: Tsitou V.M. , Rallis D. , Gergova R.
Published: October 2024

The COVID-19 pandemic, driven by SARS-CoV-2, has profoundly affected global healthcare, chal¬lenging both medical and dental practices. Emerging in Wuhan, China, in December 2019, COVID-19 quick¬ly escalated into a pandemic, leading the World Health Organization to declare a global health emergency. This review explores the pathogenesis, transmission, systemic health effects, and oral health implications of COVID-19. SARS-CoV-2, a beta coronavirus, spreads mainly through respiratory droplets, with aerosols and fomites also playing roles in its transmission. The virus binds strongly to the ACE2 receptor, present in res¬piratory, myocardial, and oral and nasal mucosa cells, facilitating infection and replication. The ensuing im¬mune response, critical for viral clearance, can lead to a hyperinflammatory ‚cytokine storm‘, causing severe complications like ARDS and multi-organ failure. Clinically, COVID-19 ranges from asymptomatic cases to severe systemic involvement, affecting cardiovascular, neurological, renal, and hematological systems. Oral health issues such as dysgeusia and xerostomia are increasingly noted, indicating the virus‘s broader impact. This review emphasizes the need for stringent infection control in dental practices, including enhanced pro¬tective measures and procedural adaptations. A multidisciplinary approach integrating oral health into broad¬er COVID-19 strategies is crucial. Continued research is essential to understand the long-term implications of COVID-19 and to refine preventive and therapeutic strategies, shaping future healthcare policies.
The Art of Asking and Analyzing Sensitive Questions in Breast Milk Microbiome Research
Authors: Mollova D. , Bakov K. , Zhekov M. , Iliev I.
Published: October 2024

Human milk includes, in addition to various bioactive molecules and microorganisms, that make up the “human milk microbiota (HMM)”. The breast milk microbiome is essential in gastrointestinal coloni¬zation of microbiome in children during the first 100 days of life. Microbial imbalance can be a starting point for necrotizing enterocolitis in premature infants, and can also contribute to the development of chronic diseases such as asthma and obesity later in life. In medical and biomedical research, particularly breast milk microbiome research, the use of surveys is often resorted to assess changes in the status of certain groups over a certain period. These questionnaires can focus on a specific sample and serve as an objective tool for professionals to acquire additional information. Creating a new questionnaire can be quite a challenge. The main difficulty lies in the development of an effective questionnaire for research and clinical use, meeting all legal frameworks, as well as the subsequent handling of sensitive data. The purpose of this study was to present the great need and difficulties in designing an effective survey for our research objectives. Research aimed at establishing the microbiome of breast milk and the associated pre¬diction of the gastrointestinal microbiome of the newborn has been of great importance recently. We have presented sample custom surveys that we have used to prepare and conduct various microbiome studies, and we believe that good preparation of an appropriate questionnaire contributes immensely to the overall completion of any biomedical study.

Authors: Pelkin A. , Ilieva R. , Iliev M. , Dimov S.G. , Doytchinov V.V.
Published: October 2024

The present research work summarizes the investigation of the microbial characteristics of bacterial isolates obtained from freshwater samples collected at various points throughout the Bulgarian Antarctic base “St. Kliment Ohridski” on Livingstone Island. The ability of microorganisms in psychrophilic envi¬ronments to survive and reproduce at low temperatures, lack of nutrients, and high UV radiation, suggests that they have developed specific mechanisms to overcome these extreme conditions. To understand the range of influence of these environmental factors standard microbiological techniques were used. The re¬search provides data on the influence of UV light, temperature range, determination of minimum inhibitory concentration (MIC) to different heavy metals, and 16S rDNA taxonomic identification of the isolates. Ant¬arctic microorganisms are of great interest in food, textile, and brewing industries, production of detergents, etc. The microbial composition in such hostile habitats still little affected by the anthropogenic factor is es¬sential for understanding the potential of psychrophilic microorganisms in different practical applications.

Published: October 2024

Staphylococcus aureus is a major pathogen in the postpartum period being frequently implicated as a cause of mastitis, and nursery outbreaks, among others as well as its increasing resistance to common antibiotics. This study therefore aimed at evaluating the presence of S. aureus in pregnant women attend¬ing clinics in rural towns in Eastern Cape, South Africa. A total of 82 pregnant women at 35‒37 weeks of gestation were sampled for the presence of S. aureus. Using standard microbiological methods, presump¬tive S. aureus isolates were obtained from vaginal and rectal swab samples. The isolates were confirmed by conventional polymerase chain reaction and then tested for antimicrobial susceptibility using the disc diffusion technique. Presence of resistance genes and virulence determinants were equally profiled. A to¬tal of 47 (57.3%) out of 82 pregnant women were colonized with S. aureus. Only two virulence genes PVL- 37/47 (78.7%) and eta-10/47 (21.3%) were detected in the isolates. The isolates were all resistant to penicillin G and clindamycin (100%), while resistances to tetracycline, vancomycin, rifampicin were 71% and resistance to oxacillin and erythromycin were above 80% while resistance to other antibiotics tested were below 40%. The isolates showed multiple resistance to 5-6 antimicrobials with indices ranging from 0.5-0.6. Genes encoding resistance to erythromycin (ermB), tetracycline (tetM), and rifampicin (rPOB) were found in 72.7% (34/47) of the isolates, while 15% (7/47) possessed the Bla-Z (penicillin). The high antibiotics resistance traits found in the isolates analysed indicates limited therapeutic options and portents a major threat to public health.
Fulfilling the potentials of residential solar energy in Egypt
Authors: Badr Atef
Published: October 2024

Energy plays a very important role in Egypt’s economic development, but the country has a gap between its produced energy and the demand of its growing population. Utilization of solar power systems in Egypt could help the country to close this gap and fulfil its national and international obligations. However, since 1980, the focus in Egypt has been on large-scale industrial solar projects. Limited attention is given to smaller systems for typical residential buildings. The aim of this research, therefore, is to highlight the potential of small residential solar systems (SRSS) in Egypt. With the huge number of residential buildings accommodating more than 115 million Egyptians, SRSS could be the unearthed gem of a sustainable source of energy in Egypt. The geographical location of Egypt and climate were used to generate solar data using the Global Solar Atlas application. The amounts of monthly and annual solar irradiations were calculated and analysed to decide the best orientation of the system (facing east, west, north, and south), identify the optimum tilt angle of the system, and determine the size of the solar panels. A case study was used to illustrate the procedures of designing SRSS for a typical residential building in Egypt. The results showed that a 26 kWp SRSS oriented facing the east with an optimum tilt angle between 15° and 30° could produce an annual total output of electricity more than the annual demand of the occupants of the studied residential building. Such a system would fit easily on the roof of the building. It was concluded that the installation of SRSS in Egypt could help the country meet the demand of its ever-increasing population if properly regulated, financed, and managed. It is recommended that Egypt develop and implement policies to make installations of SRSS an attractive choice among homeowners and investors by introducing encouraging incentives and creating a competitive market with affordable SRSS.
Los validos valencianos del valido. Arte y legitimación social en tiempos del Duque de Lerma (1599-1625)
Authors: Campo-Perales Àngel
Published: October 2024

Tomando como punto de partida ciertos detalles biográficos del vicecanciller Andrés Roig (1564-1622), algunos inéditos, este artículo reflexiona en torno al modo de vida nobiliario de aquellos protegidos por el duque de Lerma que, como Roig, medraron a la sombra del valido. Un discurso en tres actos (medrar, vivir, morir) en el que se pone en el centro del debate la importancia del objeto artístico para destacar socialmente. En una sociedad en la que la apariencia lo es todo, en vida y en muerte, los cargos y títulos conseguidos requieren de una complementaria «ostentación, fausto y magnificencia», en palabras del mismo Roig. El caso valenciano ofrece ejemplos muy representativos y poco estudiados de la práctica del valimiento, sobre todo por cuanto el duque de Lerma poseía allí todos sus estados patrimoniales no castellanos y notables intereses que trató de consolidar.

Authors: Singh Indeevar , Dabhade Vikram , Debata Mayadhar , Panigrahi Ajit
Published: October 2024

The potential advantage of adding niobium to tungsten heavy alloys owing to its lower thermal conductivity and specific heat beneficiary for kinetic energy penetrator is still unexplored. To explore this uncharted area, the effect of Nb addition in WHA for its sinterability, densification and microstructure attributes is investigated. In this study two different compositions of 90W – 7:3(Ni:Fe) and 90W – 6:2:2 (Ni:Fe:Co) were blended with 2.5 wt % Nb followed by compaction and sintered in a reducing atmosphere at 1500 oC. The finding suggested larger tungsten grain formation with Nb addition in both the alloy compositions along with formation of Nb-oxides and W-Nb intermetallics. Increasing Nb concentration hindered sinterability and densification for alloys due to Nb-Oxide formation. This study offer insight into the use of niobium as a promising alloying element in tungsten-heavy alloys (WHA).

Nitrogen-alloyed austenitic nickel-free stainless steels (ANFSS) are known for their good corrosion resistance and mechanical properties, and stable non-magnetic nature. As long as the nitrogen content remains within certain limits, increasing the nitrogen content generally improves all the said properties. However, if the nitrogen content is increased up to a too high level, ductile-to-brittle transition may take place. The optimal nitrogen level is determined by other alloying elements that can have a role in stabilizing the austenite and increasing nitrogen solubility in the melt during manufacturing. In this research, we investigate how to control the nitrogen content of nominally Fe-16Mn-14Cr-0.27C-0.35N steel during direct energy deposition processing using the mixtures of powders representing the nominal composition and subjected to a nitriding treatment. An emphasis is placed on the corrosion and mechanical properties of the resulting alloy, which we aim to explain by the analyses of material chemical composition and microstructure.

Spark plasma sintering (SPS) technology is used to sinter a large range of materials in a very short time. One of the challenges of using this process is to control the final dimension of complex shaped parts. In order to predict the compaction of the powder during a SPS cycle, we develop numerical models which take into account several physical laws involved during sintering such as creep behavior at high temperatures (viscoplasticity). In this study, the deformation model is fitted on an experimental densification curve of a nickel-based superalloy and implemented via the Abaqus® software in a thermal-electrical-mechanical model of the SPS process. A comparison of the numerical outputs with the experimental data shows a good agreement. The results demonstrate the capability to simulate accurately the sintering of powder with a limited number of experimental adjusted parameters compared to literature and to decrease significantly simulation run-time.

A spike in public attention on whether wearing masks will increase microplastics (MPs) inhalation has recently been triggered by the major transformation in widespread masking in public ever since the pandemic. To timely address this question and provide reliable insights for public health recommendations, mask users, and producers, we developed a platform based on a custom inhalation simulator, and conducted comparative measurements to investigate masks as both a source of MP release and a barrier to MP inhalation. We examined 209 mask brands from 46 countries/regions, covering multiple filtration and quality levels. Our kinetic study revealed that MP leaching primarily occurs during the initial period of wearing a new mask. Subsequently, masks act as a barrier, reducing MP inhalation compared to not wearing a mask. Hence, frequently changing masks or using masks from unproper manufacture process may not be a wise choice. We also observed significant variations in MP inhalation character among different quality levels and brands, indicating the need of future safety standards to this end. Overall, the estimated worldwide inhalation of MPs during the pandemic office hours is 1.16 times that of the pre-pandemic era. However, the impact of MP inhalation could be changed by wearing masks with higher filtration grade (and better quality). For instance, if everyone were to wear FFP-3 masks, a 28.8% reduction in MP inhalation would be expected compared to not wearing a mask.

Kınalı keklik (Alectoris chukar), Türkiye'deki en popüler av kuşlarından biridir. Bu türün nesli son yüzyılda önemli ölçüde azalmıştır. Bu kuş türünü çoğaltmak, doğaya bırakmak, ülkemizde av turizmini geliştirmek, belirli av alan-ları oluşturmak ve av turizminden gelir elde etmek mümkündür. Kınalı keklik (Alectoris chukar), Türkiye'de ve dünyada geniş alanlarda bulunur. Ne yazık ki, ülke genelinde insan baskısı nedeniyle nüfusları azalıyor. Bu türün popülasyonunu artırmak ve avlanmaya uygun hale getirmek amacıyla Türkiye'de üretim istasyonları kurulmuştur. Üretim istasyonları nesli azalan türlerin yapay olarak üretildiği ve üretim için gerekli tesislerin kurulduğu alanlardır. Başlıca amaçları, yapay olarak kurulan tesislerde türleri yaygın olarak üretmek, bu hayvanları uygun habitatlara veya yeni üretim istasyonlarına yerleştirmek ve üretim istasyonlarına yerleştirilen hayvanlardan damızlık olarak faydalanmaktır. Türkiye'de bazı insanlar için keklik yetiştiriciliği sadece bir hobi olmasına rağmen, son yıllarda neslinin devamını sağlamak için bazı devlet kurumları ve üniversitelerin Ziraat ve Veteriner Fakültelerinde araştır-ma amaçlı olarak yapılmaktadır.

Published: October 2024

Este estudio se enfoca en realizar un análisis del gasto en seguridad nacional y su impacto en el desarrollo económico del país durante el periodo comprendido entre los años 2004 y 2023. Se utilizó un enfoque que combinó métodos cuantitativos y cualitativos para analizar cómo variables relacionadas con la seguridad nacional afectan la Formación Bruta de Capital Fijo (FBKF) en Ecuador.
Se empleó un modelo de regresión lineal múltiple utilizando el método de Mínimos Cuadrados Ordinarios (MCO) en RStudio. Se normalizaron los datos para compatibilidad y se verificaron supuestos como normalidad, homocedasticidad y multicolinealidad.
Tras analizar los datos recolectados desde 2004 hasta 2023, se encontró que las variables significativas que impactan positiva o negativamente en la FBKF son la Policía Nacional, la Defensa Nacional y la tasa de homicidios. Se descartaron otras variables como el Consejo de Seguridad Nacional, la Agencia Nacional de Tránsito y el desempleo por su falta de significancia estadística.
Este análisis resalta la importancia de políticas de seguridad efectivas para fomentar un entorno propicio para la inversión y el desarrollo económico sostenible en Ecuador. Es crucial que las decisiones de política pública consideren estos resultados para promover un crecimiento económico robusto y mitigar los impactos negativos de la inseguridad.
Este estudio proporciona una comprensión detallada de cómo la seguridad nacional influye en la inversión en activos fijos en Ecuador, destacando la necesidad de estrategias integrales para mejorar la seguridad y promover el desarrollo económico a largo plazo.
A közszereplők bírálhatóságának legújabb gyakorlata a közösségi médiához kapcsolódó újabb felsőbírósági gyakorlat tükrében
Authors: Krisztián Kovács
Published: October 2024

A tanulmány a közszereplőkre vonatkozó joggyakorlat közelmúltbeli fejlődését vizsgálja, különös tekintettel a közösségi médiához valamilyen módon kapcsolódó esetekre. Bemutatja a közszereplő fogalmának változását, a kapcsolódó jogszabályi módosításokat, ezt követően tér rá az egyes döntések részletesebb elemzésére. Fontos látni, hogy az utóbbi évtizedek eltolódást eredményeztek: a bíróságok ma már nem a közszereplő mint személy, hanem a közérdeklődésre számot tartó ügyek felől közelítik meg a kérdést a személyiségvédelmi perekben. A közszereplést vállalók bírálhatósága, a velük kapcsolatos vélemények közlése nélkülözhetetlen a közbeszéd alakítása szempontjából. Az utóbbi 10-15 év technikai fejlődése oda vezetett, hogy – főként a közösségi platformok miatt – a véleménycserék rendkívül gyorsak és intenzívek. Az esetek elemzése rávilágít arra is, hogy a közösségimédia-felületek esetleges zártsága kihatással lehet-e az elkövetett jogsértésekre.
