Authors: Souza Gisele Anastácio de , Rossetin Ana Paula Dallagassa
Published: January 2025

A prática do brincar é uma figura de comunicação por meio da qual a criança se desenvolve integralmente, abrangendo os aspectos físico, social, como cultural, afetivo, emocional e/ou cognitivo. Pela mediação da brincadeira, a criança pode potencializar suas capacidades importantes, como a atenção, interação, concentração, memória, imitação, imaginação, entre outras habilidades. Para Vygotsky, o brincar é essencial para o desenvolvimento cognitivo da criança, pois os processos de simbolização e de representação conduzem ao pensamento abstrato. Além disso, o brincar contribui para o desenvolvimento da personalidade, da motricidade, do intelecto e da criatividade. É de grande relevância a prática do brincar na Educação Infantil, principalmente na primeira infância (compreendida de 0 a 6 anos de idade), um dos períodos fundamentais, no qual ocorre o desenvolvimento de estruturas e circuitos cerebrais. Através desta prática, a criança demonstra toda sua agilidade, crescimento e desenvolvimento nos aspectos sociais e culturais, bem como investiga o papel do educador nessa importante vivência. O trabalho apurou como uma criança, através da brincadeira, fortalece sua personalidade e habilidades, exerce sua imaginação, representa sua autonomia em diversas atividades, desenvolve suas emoções e amplia sua visão ao participar de atividades lúdicas, descobrindo assim o mundo dentro do universo escolar.

Authors: Khan Nabiullah , Sk Rakibul , Husain Saddam
Published: January 2025

In this study, we present and explore extended beta matrix functions (EBMFs) and their key properties. By utilizing the beta matrix function (BMF), we introduce novel extensions of the Gauss hypergeometric matrix function (GHMF) and Kummer hypergeometric matrix function (KHMF). We delve into their integral representations, recurrence relations, transformation properties, and differential formulas. Additionally, we investigate their statistical applications, mainly focusing on the beta distribution, and derive expressions for the mean, variance, and moment-generating functions. Furthermore, we apply EBMFs to develop the Appell matrix function (AMF) and Lauricella matrix function (LMF) and their integral forms.

The serious GIT side effects of NSAIDs, due to their carboxylic acid groups, aroused the attention of researchers to manipulate such drugs. Conjugates with NSAIDs are a strategic, way for both augmenting the anti-inflammatory activities and reducing side effects. Natural or synthetic coumarins are interesting motifs for anti-inflammatory activity. The scope of this work was to conjugate NSAIDs (ibuprofen, diclofenac, mefenamic acid, ketorolac and indomethacin) with various substituted coumarins through an ester or amide linkages using a virtual screening molecular docking study to investigate their anti-inflammatory activities. COX-1, COX-2, phospholipase A2, and carbonic anhydrase were selected to study the anti-inflammatory activities. Results showed that 20 compounds (out of 75) could be considered as having such effects with scores more than those of the standard inhibitors. These compounds display talented docking connections with the active site in each enzyme with different antiinflammatory mechanisms. The estimation of the kinetic-pharmacological performance and the drugs similarity (drug-likeness) for the tested compound according to the ADME study were encouraging with respect to gastrointestinal (GI) absorption, circulation bioavailability and overall drugs similarity, so there is a good chance for these compounds to be established as real drugs

Published: January 2025

This study investigates the evolving causal relationship between government revenue and expenditure in Algeria from 1980 to 2022, a period marked by significant fiscal policy shifts. Unlike previous research assuming a static relationship, we employ a bootstrap rolling window approach and spectral Granger-causality test to capture time-varying causality. These methods illuminate the dynamic nature of fiscal interactions in Algeria's changing economic landscape. Our findings robustly support the tax-spend hypothesis over extended periods, revealing that government revenues significantly influence expenditure patterns. Notably, from 1995 to 2003, we observe a positive effect on spending, coinciding with fiscal contraction and rationalization efforts. Conversely, despite declining tax revenues from 2005 to 2008, an expansionary fiscal policy increased spending, indicative of financial illusion. Interestingly, we also find intermittent short-term evidence supporting both the spend-tax and fiscal synchronization hypotheses, highlighting the complex and multifaceted nature of Algeria's fiscal dynamics. The spectral Granger-causality tests further corroborate these findings, particularly in the medium term. This study contributes to the literature on fiscal policy dynamics in resource-dependent economies and offers valuable insights for policymakers navigating Algeria's complex fiscal landscape. Our results underscore the importance of adaptive fiscal strategies that account for the time-varying nature of revenue-expenditure relationships, particularly in the face of oil price volatility and economic diversification efforts.

Authors: Ferfoglia Peter , Valić Tamara Besednjak , Uršič Erika Džajić
Published: January 2025

Managing employee emotions can lead to an improvement in the corporate climate and therefore to better cohesion of the corporate social network. In reality with many employees, especially those where people are spread over vast territories, the difficulties in detecting emotions become greater. Hypothesizing the usefulness of emoji-emoticons to simplify the recognition of emotions even in complex situations, we have carried out a literature review of the scientific articles which talk about emotions and emoji-emoticons. Our job consisted in researching, cataloguing and summarizing the main studies done and published by researchers in the last ten years concerning emotions and the use of emojis as a tool for the discovery and understanding of emotions in corporate working groups, to then make a brief analysis. Much research has been done and many methods have been developed in the field of emotional-sentimental detection, just as there is much research relating to the generic use of emojis, in general, and in the corporate field. Unfortunately, we have found few studies regarding the use of emojis for emotion recognition and identification in the workplace. As a result, we have found scientific evidence of the importance of emotions in companies, noting that the different types of graphic inserts (emoji-emoticons) can be a valid support tool for human resources for detecting and analysing employee emotions. We believe we have achieved the goal of our work in providing concrete help with this literature review for future scientific developments in this field

Published: January 2025

Penelitian ini bertujuan untuk mengkaji perlindungan hukum terhadap data pribadi dalam konteks perkembangan teknologi digital, dengan fokus pada Undang-Undang Nomor 27 Tahun 2022 tentang Perlindungan Data Pribadi (UU PDP). Jenis penelitian ini adalah penelitian hukum normatif dengan pendekatan perundang-undangan. Teknik pengumpulan data dilakukan melalui studi pustaka, dan data dianalisis secara deskriptif kualitatif. Hasil penelitian menunjukkan bahwa pesatnya perkembangan teknologi informasi telah membawa dampak signifikan pada berbagai aspek kehidupan manusia, termasuk pengelolaan data pribadi. Data pribadi kini menjadi aset yang sangat bernilai dan rentan terhadap penyalahgunaan, yang dapat mengakibatkan konsekuensi negatif seperti penipuan, pencurian identitas, dan pelanggaran privasi. UU PDP dirancang untuk memberikan perlindungan hukum terhadap data pribadi dengan mengatur pengumpulan, pengolahan, dan pemanfaatannya, serta menetapkan sanksi bagi pihak yang melanggar ketentuan tersebut. Sebelumnya, perlindungan data pribadi tersebar dalam regulasi sektoral yang tidak komprehensif. Kasus kebocoran data di beberapa platform besar seperti Tokopedia, KreditPlus, BPJS Kesehatan, SIM Card, dan BSI menunjukkan adanya celah dalam sistem keamanan yang perlu diperbaiki, baik dalam perangkat lunak maupun dari sisi human error. Oleh karena itu, sistem keamanan yang lebih kuat, seperti enkripsi data, autentikasi ganda, dan pembaruan perangkat lunak secara berkala, sangat diperlukan. UU PDP memberikan perlindungan hukum preventif dengan mewajibkan persetujuan dari subjek data, hak akses dan pembaruan data, serta kewajiban pengendali data untuk melaporkan kebocoran data. Perlindungan represif berupa sanksi administratif, pidana, dan perdata juga diterapkan bagi pelanggaran. Namun, implementasi UU PDP memerlukan peraturan pemerintah dan pembentukan lembaga independen yang dapat mengawasi pelaksanaan perlindungan data pribadi secara efektif. Penelitian ini penting untuk mendorong penguatan regulasi dan mekanisme pengawasan guna memastikan perlindungan data pribadi yang optimal di era digital.

Authors: Xu Wentao
Published: January 2025

This study delves into the significant role and prospects of additive manufacturing in lightweight design for the aerospace and automotive industries. As these two industries continuously demand lightweight and high-performance materials, traditional manufacturing methods have become inadequate to meet increasingly complex design requirements. Additive manufacturing, an advanced technology that constructs objects by layering materials, has gradually emerged as a key solution to this challenge. By integrating advanced techniques such as topology optimization and porous grid/lattice design, additive manufacturing not only enables the production of complex and intricate components but also significantly reduces material usage and product weight while maintaining or enhancing structural performance. This is particularly crucial in the aerospace and automotive industries, where lightweight design can directly improve energy efficiency and operational performance. Research indicates that additive manufacturing has successfully produced lightweight components that meet or exceed industry performance standards. This not only confirms the vast potential of additive manufacturing in modern manufacturing but also foreshadows its increasingly important role in future material utilization and structural design. Overall, this study highlights the current advancements of additive manufacturing in lightweight design and anticipates its broad application prospects, especially in promoting more efficient and environmentally friendly production methods in the aerospace and automotive industries.

SilentPlay. Percorsi di ricerca tra tecnologie audio e teatro partecipativo
Authors: Presotto Carlo , Zardini Lacedelli Stefania
Published: January 2025

Negli ultimi decenni, il suono e le tecnologie audio si sono fatte sempre più spazio nella ricerca teatrale, dando origine a nuove modalità performative che hanno consolidato tre tendenze in atto: la fuoriuscita dai luoghi tradizionali, la partecipazione del pubblico alle azioni sceniche e alla creazione della drammaturgia, e l’uso delle tecnologie per attivare nuove modalità di percezione, interazione e relazione. Questo articolo esplora la genesi, le fasi di sviluppo e l’impatto del SilentPlay, un percorso di ricerca incentrato sull’uso delle tecnologie audio in cuffia avviato nel 2009 dal centro di produzione teatrale La Piccionaia. In questo formato di drammaturgia sonora, i partecipanti sono guidati all’esplorazione di luoghi da un conduttore performer che, mediante l’uso di cuffie wireless, trasmette tracce audio registrate e stimola l’interazione dei partecipanti. L’articolo analizza le confluenze con le sperimentazioni del teatro ragazzi, il teatro partecipativo e le passeggiate sonore e descrive le due principali direzioni di sviluppo: la messa in scena del racconto latente dei luoghi e lo sviluppo di dispositivi di eterodirezione del pubblico (Lietti, 2016). L’esperienza del SilentPlay offre al suono la possibilità di essere non solo veicolo complementare, ma elemento primario della produzione creativa che può ispirare anche altre pratiche di coinvolgimento culturale.
Corpi sonori queer

Published: January 2025

L’obiettivo di questa ricerca è indagare il ruolo della pratica performativa del dj set per soggettività e comunità queer. Indaghiamo la formazione di culture e scene musicali queer come sinergia tra dimensione musicale e sessuale (Taylor 2008, 2012) basate sull’inclusione e l’accoglienza di gusti musicali e soggettività di vario genere. Ci soffermiamo in particolare sull’elettronica come luogo sperimentazioni musicali, tecnologiche, artistiche transfemministe e queer (Attimonelli 2018; Attimonelli, Tomeo 2022) e sul ruolo sociale del dj set, esplorando il suono come artefatto e come spazio. Proponiamo una metodologia basata su momenti etnografici ed interviste ad esponenti di una scena cittadina, con percorsi, esperienze e forme espressive differenti. L’analisi attraverso la lente del genere fa emergere forme diverse di attivismo al di fuori dalle logiche sessiste e pratiche di queerizzazione e rinegoziazione di spazi nell’ottica di creazioni di safer spaces.
Mineral Entrails
Authors: Monteanni Luigi
Published: January 2025

In the 1980s, Napalm Death founded grindcore: a musical subgenre at the crossroads of extreme metal, anarcho-punk and hardcore. The style aimed at sonic extremity interpreted as a wall of sound: an aesthetic stimulated by its working-class origins. Grindcore has subsequently influenced various extreme musical practices that sound the relationship between class and capitalism. From Japanese noise to American jazzcore to British electronic music, the genre’s approach reverberates as a bodily philosophy of audio. By framing this phenomenon of resonance between transnational genres, my aim is to declare them part of a ‘sound-as-physical-assault’ continuum, based on extreme/intense aesthetic experiences of sound. Starting from Brar’s notion of ‘mineral interiors’, which describes how the intensity of sound in Afrodiasporic musical currents resonates both a space in the record and in the listener’s world, I suggest that the same theorisation of an intensity-based sound ecology can be applied to grindcore, jazzcore and japanoise as well as genres such as dub and footwork. While both participate in the same paradigm of music based on haptic intensity and class issues, the two concepts are different in terms of political imagination and psychophysical effects of music. This contribution ensures the possibility of highlighting phonic and sociopolitical similarities while maintaining differences between musical genealogies that share a maximalist use of sound systems.

Authors: RAO FJ , HASSAN A , SARWER AR , ATIF G
Published: January 2025

Postoperative atrial fibrillation (POAF) is a common complication following coronary artery bypass grafting (CABG), associated with increased morbidity, prolonged hospitalization, and higher healthcare costs. Posterior pericardiotomy, a surgical technique that facilitates the drainage of pericardial fluid into the pleural cavity, has been proposed as a preventive measure against POAF. Objective: To evaluate the effectiveness of posterior pericardiotomy in reducing the incidence of POAF in patients undergoing CABG at the Punjab Institute of Cardiology, Lahore, Pakistan. Methods: This randomized controlled trial included 94 patients undergoing CABG, randomized into two groups: Group A (posterior pericardiotomy) and Group B (control). Demographic data, POAF incidence, and postoperative outcomes were collected. Statistical analysis was conducted using SPSS version 20, with a p-value ≤0.05 considered significant. Results: The incidence of POAF was significantly lower in Group A (6.4%) compared to Group B (25.5%) (p=0.014). Group A also exhibited a shorter hospital stay (7.8 ± 1.4 days vs. 8.5 ± 1.6 days; p=0.021) and a lower incidence of pericardial effusion (4.3% vs. 21.3%; p=0.032). Both groups were comparable in baseline demographics and comorbidities. Conclusion: Posterior pericardiotomy significantly reduces the incidence of POAF, pericardial effusion, and hospital stay duration in CABG patients. These findings support its use as a safe and effective intervention to improve postoperative outcomes in resource-limited settings like Pakistan.

High temperature is one of the restricting and consistently approaching dangers to cotton efficiency in Pakistan. It has given a big loss in the recent few years. The plant parts like seedlings, bolls, and fiber quality attributes are incredibly affected because of high temperature. Production of cotton is decreasing due to many reasons mainly pest infestation and high temperatures. To fill the yield gap, an experiment was conducted in which different concentrations of plant extracts i.e. Sugar Beet Root Extract (1%), Watermelon Juice (1%), Moringa Leaf Extract (1%), Jantar Leaf Extract (1%), Spanish Leaf Extract (2%), Carrot Root Extract (1%), Ginger Root Extract (1%), and Lemon Juice (1%) were used. All growth-promoting substances had a significant impact on crop growth and yield attributes. However, maximum yield was associated with priming of seeds with moringa leaf extract (3%). Germination percentage (86.5), number of bolls plant-1(54.7), yield (3.5 tons ha-1), biological yield (11.8 tons ha-1), and harvest index (31.5) were significantly boosted by moringa leaf juice as priming agent. Based on the experiment, different parameters on the growth and yield of cotton were examined and analyzed statistically by using the least significant digit (LSD) at 5% through standard procedures.

Blockchain for Migrants: Promoting Self-Sovereign Identity and Financial Inclusion
Authors: Vasselin Francoise
Published: January 2025

This article explores the potential of Distributed Ledger Technology (DLT), with a focus on blockchain, to address key challenges related to the security, ownership, and management of personal data. We trace the foundational work of Haber and Stornetta, who introduced the core principles of blockchain to secure digital records within the real economy. Building on this, Nakamoto’s innovations in blockchain technology introduced a native crypto-asset, which not only aligns and concentrates the interests of network participants but also resolves the previously unsolved “double-spending problem.” This breakthrough decentralizes the verification and control of recorded information, enhancing security in monetary transactions.Migrants often face challenges related to rights protection, identity management, and limited access to financial services. Blockchain applications, with their strengths in secure data storage, transparent transactions, and reliable identity verification, offer promising solutions. In this article, we examine real-world blockchain applications that enhance identity management and foster financial inclusion for migrants. Blockchain provides an infrastructure that empowers individuals with greater control over their financial and personal data, particularly through self-sovereign identity (SSI) and the use of stablecoins as global currencies. These innovations are becoming foundational components of a new digital ecosystem for information and finance.
Investigation of splitting of a beam of potassium atoms in the classical Stern-Gerlach experiment at varying inhomogeneity of the magnetic field
Authors: Akhmetova Asel'
Published: January 2025

The splitting of a beam of potassium atoms in the classical Stern-Gerlach scheme under varying inhomogeneity of the magnetic field is experimentally investigated in this work. First, the basic shape of the beam in the absence of an effective field is recorded, which makes it possible to introduce and calibrate the geometrical parameters of the channel. Then, when the current in the magnet windings increases and the field gradient grows, a systematic shift of the beam density maxima is observed, described by the model function F(u), which includes the parameter q, which characterizes the strength of interaction of atoms with the field. Theoretical calculations based on this function showed good agreement with the experimental results, including the asymmetry of the distribution due to the nonideal symmetry of the magnetic system. The obtained dependences of the position of the intensity maxima on ∇B confirmed the validity of both linear and asymptotic approximation for different modes of magnet operation. These conclusions have both fundamental importance for understanding the quantum mechanical aspects of beam splitting and applied significance in the development of methods for precise control of spin-polarized atomic beams in spectroscopy and spintronics.

Published: January 2025

This study presents a comparative analysis of the capabilities of Large Language Models (LLMs) in the automatic detection of fake news. The research focuses on evaluating the accuracy, precision, recall and F1-score of three state-of-the-art LLMs—OpenAI’s ChatGPT 4.0 beta, Meta’s Llama 3.1, and Google’s Gemini—using an extensive dataset of verified true and fake news. By employing a black-box testing method, the study categorizes the LLMs’ outputs and assesses their performance based on accuracy metrics. The results indicate moderate success in distinguishing between true and false news, with differences noted between the models and smaller, text classification specialized Natural Language Models (NLP), like Google‘s Bidirectional Encoder Representations from Transformers (BERT) model variants, trained on the same fake news dataset. The findings demonstrate the potential of LLMs as tools for combating misinformation, while also emphasizing the current limitations and the need for improvements in their accuracy and reliability. This paper provides insights into the challenges of utilizing LLMs for misinformation detection and highlights the importance of combining technological advancements with our distinct human cognition.
