Traumatic brain injury (TBI) is a pervasive public health concern globally, with millions of reported cases annually. This study investigates the impact of TBI on neurobehavioral deficits, electrolytes and lipid metabolism in albino rat models at different time points within 24 hours. Twenty-eight albino rats were randomly divided into four groups of seven rats each; Group I (Non traumatized, Control), Group II (Traumatized and sacrificed at 0 minute), Group III (Traumatized and sacrificed at 30 minutes), Group IV (Traumatized and sacrificed at 1hour), Group V (Traumatized and sacrificed at 24 hours). TBI was induced using a weight drop method after anesthesia with xylazine and ketamine at 5mg/kg and 80mg/kg respectively. A neurological severity test was carried out to determine the neurobehavioral deficits of rats in all the experimental groups. Blood sample was collected after sacrifice at 0 hour, 30 minutes, 1hour, and 24hours respectively in plain sample bottle, and serum was collected for electrolyte and lipid profiles. A mild neurological impact at 30 minutes, 1 hour, and 24 hours post-injury was recorded as indicated by the lack of progression in the NSS-R score. There was a significant increase in sodium, potassium and chloride after TBI.Lipid profile analysis showed a significant increase in total cholesterol levels, while triglyceride levels remain stable post-TBI. High-density lipoprotein cholesterol (HDL-c) was significantly decreased post-TBI, while Low-density lipoprotein cholesterol (LDL-c) levels had no significant change post-TBI. Induction of traumatic brain injury can result in profound electrolyte imbalance and dyslipidemia within 24 hours, thus serving as baseline data for proposed therapeutic interventions.

Published: January 2025

This study aims to analyze the impact of accounting information systems and financial management on financial performance, with remuneration as a mediating variable. Using a quantitative approach, the research involved 36 respondents from Eyelink Group and its branches. Data were collected through questionnaires and analyzed using Structural Equation Modelling (SEM) with SmartPLS software. The findings indicate that accounting information systems have a positive and significant effect on remuneration, and remuneration positively affects financial performance. However, financial management does not have a direct significant impact on financial performance. Additionally, remuneration mediates the relationship between accounting information systems and financial performance but does not mediate the relationship between financial management and financial performance. These findings provide valuable insights for companies to optimize the use of accounting information systems and remuneration policies to enhance financial performance.
Research on Path Planning of Warehouse Robots Based on Q-learning
Authors: Song Yuzeyuan
Published: January 2025

The rapid growth of e-commerce has intensified the demand for efficient warehouse management and automation. This research focuses on applying Q-learning, a reinforcement learning algorithm, to the path planning of warehouse robots. Path planning is a critical aspect of warehouse robotics, particularly in dynamic environments where efficient navigation can significantly enhance operational productivity. This study aims to develop a Q-learning-based algorithm that enables warehouse robots to navigate their workspace effectively, minimizing the time taken to reach designated goals while avoiding obstacles. The approach involves constructing a grid world model to simulate the warehouse environment, where the robot learns to make optimal decisions based on rewards and penalties associated with reaching goals and colliding with obstacles, respectively. By modeling the warehouse as a discrete grid with obstacles and defining the robot's task cycle—from starting point to cargo pickup to delivery, and return—this study investigates how varying the learning rate (α) and discount factor (γ) affects the robot's learning efficiency and path optimization. A full-factor experiment testing 81 combinations of α and γ revealed that higher values of γ, especially when paired with appropriate α values, significantly reduce the number of steps required for task completion and decrease path-planning failures. The findings underscore the importance of parameter tuning in Q-learning algorithms to enhance the efficiency and reliability of autonomous warehouse robots.
In Amateur Death. A Reflection on Snuff Movies
Authors: Riccobene Enrico M.
Published: January 2025

The study of amateur cinema gives rise to ethical and aesthetic dilemmas that are well- known to anyone who has engaged in such research (see, for example, Caneppele 2022). However, there has been little attention paid to a particular and extreme type of film that, while sharing stylistic features and production methods with amateur cinema, differs significantly in content: snuff movies. The term snuff movie is used to describe films or videos that depict scenes of real violence, including torture, murder, and rape. Although the revulsion provoked by such imagery confines this genre to a limited audience, it is evident that interrogating the manifestations of violence when captured on film (even if done in an amateurish manner) can rekindle dormant discussions on the essence of the medium. Even if unconsciously, Pasolini begins his examination of the sequence plan from a snuff movie, the most famous of which is the Kennedy assassination filmed by Zapruder (Pasolini 1967). Furthermore, ethical concerns pertaining to death and cinema are extensively discussed by Bazin (Bazin 1951). More recently, Nancy has addressed the issue of violence in and of images (Nancy 2002). The three cases presented here illustrate the dilemmas underlying reflections on cinema, which have been accelerated by the exponential expansion of digital amateur cinema. With the spread of smartphones, any murder or suicide has the potential to become a snuff movie, as evidenced by the growth of dedicated telegram channels, which have replaced the older “shock sites” and the circulation of images in the obscure world of the deep web. These images are often leaked from judicial investigations. It is evident that these images are not intended for public viewing. Nevertheless, they exist, they spread, and they intrigue. This contribution is not intended as a definitive theorization of the snuff film, but rather as a starting point, a proposal that – starting from a review of some distinctive formal and productive features common to all the artefacts more or less correctly identified as snuff films – may initiate a reflection that contextualizes these products within the studies of amateur cinema, trying to trace the reasons why these stylistic peculiarities may correspond to a greater degree of realism in the perception of the “spectator”.
Il sublime nei miseri e disgustanti avanzi di un corpo morto
Authors: Rinaldi Simona
Published: January 2025

In medieval literature the physical remains of martyrs and saints are described as shining gems, or fragrant flowers in the name of a spiritualiter apprehension for which the brute and disgusting matter of bones or mummified flesh is elevated to the highest good and highest beauty, that is, to the status of “relic”. The faithful-spectator therefore experiences a conversion of vision to which the reliquary contributes with its sensual guise and its dialectic of hiding/showing.
Even the precious textiles that wrap the relics play an active role in this ethical-aesthetic mediation, being capable of triggering symbolic associations gravitating around the Christian theology of clothing. The starting point is the parallelism established by Thiofrid of Echternach († 1110) between the reliquary and the appearances of the Eucharistic bread and wine defined as velamen placed to cover the substance of the body and blood of the crucified Christ which, if shown, would have disgusted the faithful.
A quick foray into contemporary art will demonstrate the persistent vitality of the notion of relic and the mechanism of veiling/dressing that belongs to the reliquary, to this powerful device for presenting the unpresentable.
L’eccesso corporeo in Pinocchio tra disordine, comico e cultura popolare
Authors: De Gasperis Arianna
Published: January 2025

This paper examines some essential dichotomies in Carlo Collodi’s Le avventure di Pi- nocchio. Storia di un burattino through its implications on the level of comic and popular culture. On the one hand, starting from chapters I-III and VIII, it analyses Collodi’s reflec- tion on artistic creation and its connection with fatherhood, especially on its binarisms («artista»/«pezzo di legno», «idea»/«burattino», reality/imagination, and so on). On the other hand, it delves into the relation between the “body” and the “order”, as well as the close connection with the issue of “transgression”, that in Pinocchio is validated both in ethic and aesthetic terms.
Tre variazioni senza tema intorno a Proust e Beethoven
Authors: Cobetto Ghiggia Paolo
Published: January 2025

Proust’s Recherche has been, and still is, an inexhaustible source of inspiration for literary and philosophical studies. This essay aims to outline the network of relationships, some- times unexpected, that emerged from the intellectual environment of these studies, especially around the BCDEs, and their mutual influences from and on other fields of human thought and arts, even beyond the boundaries of literature and philosophy. A specific case study will be considered: a monographic issue of the French magazine L’Arc published in BCDE and dedicated to the bicentenary of Beethoven’s birth. We will first focus on the analysis of Beethoven’s Diabelli Variations by André Boucourechliev, which Roland Barthes compares to the narrative structure of the Recherche. Then, through an article by Barthes himself, Musica Practica, the approach to the interpretation of Beethoven’s works will be compared to the role of Proustian criticism. Here, Barthes also highlights the importance of amateur musical practice in understanding the very essence of a musical work. Finally, Igor Stravinsky’s commentary on Beethoven’s late string quartets will be related to Proust’s reflections on the modernity of the work of art.
Digital restitution of expropriated heritage: technological modes of experience
Authors: Calise Anna
Published: January 2025

For more than a century now, Western museological institutions have been exhibiting expropriated heritage across their museum spaces, curating displays which conveyed prescriptive epistemic paradigms, informed by a rigidly imposed notion of primitive aesthetic. As the restitution of physical heritage is at the center of the international political debate, both museums and artists have started to employ digital technologies to engage with the looted heritage, envisioning new paths for access and experience, through projects which aspire to question traditional narratives. Interestingly, digital technologies offer the opportunity to mobilize a very rigid state of affairs, overcoming diplomatic stances and shifting the debate towards questions of identity, values and aesthetics. This paper intercepts the digital repatriation phenomenon, analyzing two case studies which relate to the Benin Bronzes: the international cooperative institutional programme Digital Benin and the AI generated work Igùn (2020) by artist Minne Atairu. These two projects, in their own media specific ways, create new modes of experience to interact with the Benin Kingdom heritage, operating at the intersection between research, display, creativity and meaning making. As the digital restitution debate becomes more and more pressing in the current scenario, the research offers an analysis of how digital technologies can be used to foster new paths to engage with expropriated heritage, overcoming rigid definitions of knowledge.
Czech Republic: Independent Tax Policy as a Part of Czech Fiscal Policy
Authors: Radvan Michal
Published: January 2025

Tax issues are often considered crucial to public financing. Many state policies depend on tax revenue. The state sets its tax policy to collect adequate income in order to ensure the management of the state and local self-government units. The position of tax law within the system of law is perceived in a variety of ways in the world and in European Union (EU) Member States. For example, in Western European countries (the old EU Member States), tax law and tax law science have long-standing traditions. Tax law is an independent branch of European law. In the new EU Member States (Central and Eastern Europe), tax law is (still) a sub-branch of financial law according to the local legal sciences; specifically, it pertains to the fiscal part of financial law, which deals with the legal relationships created, implemented, and terminated in the process of creating, distributing, and using public monetary funds. The fiscal part of financial law includes, in addition to tax law (public budget revenues), budgetary law, and public subsidy law (public budget expenditures). This chapter addresses the position and role of tax laws in the Czech legal system. The following sections identify the pros and cons of tax sovereignty and tax harmonisation in tax law regulations and reviews notable efforts in the tax avoidance field. The last section presents the conclusions and de lege ferenda recommendations.
Serbia: Tax Policy as Part of National Economic Governance
Authors: Popović Dušan V.
Published: January 2025

This chapter analyses three specific characteristics of Serbian tax law and policy: tax competition, the prohibition of discrimination, and the prohibition of the abuse of law. First, we analyse the extent to which the Serbian legislative and executive powers resort to tax competition. Tax competition, a form of regulatory competition, exists when governments reduce fiscal burdens to encourage the inflow of productive resources or discourage their exodus. Non-discrimination is one of the fundamental principles of international tax treaty law, which may be found in hundreds of bilateral double taxation treaties that are currently being applied globally. This principle is articulated in most tax treaties concluded by the Republic of Serbia. Finally, this chapter analyses the general anti-abuse rule, such as the one incorporated in the EU Anti-Tax Avoidance Directive, which is the ‘minimum standard’ and does not preclude the application of domestic or agreement-based provisions aimed at safeguarding a higher level of protection for domestic corporate tax bases. Notably, in the Serbian legal system, the prohibition of the abuse of law is not articulated as a general principle of tax law. Instead, the legislature introduced the principle of facticity. Both administrative and judicial case law related to the application of the principles of facticity are limited.
Serbia: Challenges for Monetary Policy During the Transition Period
Authors: Popović Dušan V.
Published: January 2025

The National Bank of Serbia, acting as a central bank, was established as an independent and autonomous institution accountable for its work in the National Assembly of the Republic of Serbia. The status, organisation, mandate, and functions of the central bank, as well as its relations with other national and international institutions, are regulated by the Constitution of the Republic of Serbia, the Act on the National Bank of Serbia, and the Statute. The National Bank of Serbia has engaged in longstanding cooperation with the European Central Bank. Over the last 20 years, the two authorities have conducted numerous cooperation projects and (in 2018) signed a memorandum of understanding. Since 2014, the National Bank of Serbia and the European Central Bank have held regular annual bilateral meetings. In addition to capacity-building cooperation agreements, the two authorities signed the Agreement on Cooperation in the area of preventing counterfeiting and detecting counterfeit euro banknotes in Serbia. Based on this agreement, the European Central Bank will deliver the technical specifications of the original euro banknotes and the classification of counterfeits to the Serbian central bank. The main challenge faced by the national authorities in recent years has been the COVID-19 crisis. Both the National Bank of Serbia and the Government undertook measures in response to the COVID-19 pandemic. The central bank’s measures consist of monetary policy and a moratorium on debt payments. In addition, the Government of Serbia adopted the Program of Economic Measures to reduce the negative effects caused by the coronavirus pandemic and support the Serbian economy. The programme included tax policy measures, direct assistance to the private sector, measures to preserve liquidity in the private sector, and other measures. Notably, the COVID-19 crisis was complemented by an energy crisis, which was further highlighted by recent geopolitical developments.

Key Factors in Children's Second Language Acquisition: Appropriate Age and Suitable Environment
Authors: Zhao Ruiying
Published: January 2025

Second language acquisition (SLA) is a key focus for educators and linguists as society becomes increasingly bilingual and multilingual. Mastering one language is no longer enough to meet global demands, prompting research into effective SLA strategies. While much of this research targets adult learners, there is growing recognition of the importance of childrens SLA. Understanding the factors that influence childrens language learning is crucial for developing effective teaching methods with both theoretical and practical relevance. Although studies on childrens SLA are limited, a consensus is emerging that early exposure and immersive environments enhance language acquisition. As economic improvements allow more parents to invest in overseas educational programs, many believe that immersion in a native-speaking environment offers the best language learning outcomes, and starting language learning early is widely accepted as beneficial. In addition to the right age and immersive environment, children's personalities and attitudes affect their learning speed. Extroverted children with positive attitudes tend to acquire language more quickly, while introverted children may progress more slowly. Parents also play a key role in facilitating language learning at home by creating an engaging English-speaking environment through activities like listening to picture book audio or watching English cartoons. For those with resources, sending children abroad before puberty for immersive experiences can provide valuable interaction with native speakers; however, it is recommended to stay for at least six months due to the common "silent period" in language learning
Research on the Formation Mechanism of Reversed News Based on the Social Combustion Theory
Authors: Guo Yankun
Published: January 2025

With the rapid rise of the Internet and new media, reversed online public opinion has become increasingly common, challenging public cognition and the principle of news authenticity. From the perspective of social combustion theory, this paper explores the mechanisms behind such reversals. Reversed public opinion resembles a "combustion" process: "combustible materials" are factors causing social instability, "accelerants" include social media platforms and public emotions, and the "ignition temperature" represents sudden impactful events. Once public emotions reach a tipping point, reversed news emerges rapidly. Self-media often rush to publish unverified information in pursuit of traffic, becoming a key source of reversals. Journalists lacking professional ethics and objectivity further intensify the phenomenon. The public, influenced by cognitive biases and emotional triggers, inadvertently amplifies these reversals during dissemination. To reduce the societal harm of reversed news, mainstream media should guide public opinion by restoring facts through authoritative reporting. Journalists must adhere to ethical principles of objectivity and truth, while the audience should enhance media literacy, approach news critically, and avoid spreading unverified information. Collaborative efforts are essential to fostering a healthy and orderly media environment where online public opinion serves societal development

Targeting HHLA2 Glycosylation via STT3A Knockout to Enhance NK Cell-Mediated Antitumor Activity in Breast Cancer
Authors: Li Jiawei
Published: January 2025

Breast cancer is one of the most prevalent and lethal cancers worldwide, with immune evasion posing a significant challenge to current therapeutic strategies. HHLA2, a recently identified immune checkpoint protein, plays a crucial role in tumor-mediated immune suppression, particularly through its interaction with NK cells. Aberrant glycosylation of HHLA2 in cancer cells contributes to immune escape by stabilizing its inhibitory effects. STT3A, an essential enzyme in the glycosylation process, is responsible for adding glycans to immune checkpoint proteins like HHLA2. This study investigates whether knocking out STT3A in MCF7 breast cancer cells using CRISPR-Cas9 technology can reduce HHLA2 glycosylation, thereby enhancing NK cell-mediated cytotoxicity. We employ a combination of in vitro assays (MTT for cell viability, mass spectrometry for glycosylation profiling) and in vivo xenograft models to assess tumor growth and immune response. The results of this study could provide valuable insights into developing novel cancer immunotherapies that target glycosylation-dependent immune evasion, offering a potential pathway to improve the prognosis for breast cancer patients
Identifying the role of circular RNA in zebrafish fin regeneration
Authors: Li Junyan , Yao Xin , Liu Hangchen
Published: January 2025

Circular RNA (circRNA) is a class of RNA with circular structures and diverse functions. In recent years, they have emerged as a key regulatory molecule with abilities to regulate stem cell differentiation and other components of the cell cycle including tumor suppression and cell cycle progression. Yet their functions in regeneration are under-investigated. We chose zebrafish as a model organism due to their remarkable regenerative capabilities, and susceptibility to genetic modifications. This study aims to explore the role of circRNAs in zebrafish caudal fin regeneration, with a specific focus on their function as miRNA sponges. Through RNA sequencing (RNA-seq) and cross-linking immunoprecipitation sequencing (CLIP-seq), we will identify differentially expressed circRNAs during the regeneration process and analyze their potential miRNA-binding sites. We will employ small hairpin RNA (shRNA) knockdown experiments to investigate the functional significance of circRNA-miRNA interactions in vivo. This will provide novel insights into the regulatory functions of circRNAs in vertebrate regeneration, with implications for advancing regenerative medicine and therapeutic strategies for human tissue repair

A Comparative Review of the DRGs Reforms in China and the U.S.: Similarities, Innovations, and Recommendations
Authors: Zhu Yiren
Published: January 2025

This research aims to identify the main similarities, differences, innovations, and challenges faced by the Diagnosis-Related Groups (s) health insurance payment reforms between the two largest world economies, the United States and China. The U.S. government initiated its DRGs reform in 1983 through the Medicare system to restrain its escalating medical service costs. The system upgraded to the Medicare Severity Diagnosis Related Groups (MS-DRGs) system later, which pays more attention to healthcare quality and patient outcomes. In contrast, China's engagement with DRGs payment reforms began much later, with its first attempt in Beijing in 2011. After years, China has progressively adopted the DRGs system into its medical insurance and hospitals. The literature reviews and case studies helped to find out that both economies share similarities in their DRGs reforms. For example, a transition from a Fee-for-Service (FFS) medical insurance settlement system to a DRGs-based system. Moreover, they share common goals of controlling total medical costs and enhancing healthcare service quality. However, there are also significant differences existing in their reform environments and functions of the government and market. Furthermore, the popularity of relevant technologies and the ability to process and collect data are also disparate. This study concludes that the implementation of DRGs payment reforms have had positive impacts on the health insurance systems for both countries, yet they still encounter challenges such as uneven regulatory intensity, policy uncertainties, and insufficient technological applications.

From Partnership to Bankruptcy: Understanding Sri Lanka's Belt and Road Experience
Authors: Liang Yongxing
Published: January 2025

Sri Lanka was among the first countries to sign China's Belt and Road Initiative (BRI) in 2014. This study examines the key factors contributing to national bankruptcy in Sri Lanka within the BRI context. Using a benchmark regression model based on time series data from 2000 to 2022, the analysis identifies significant influences on bankruptcy. The findings indicate that agricultural output and technology levels negatively impact bankruptcy, while the agricultural population and education levels have a positive effect. Additionally, trade levels, openness, and participation in the Belt and Road Initiative do not significantly influence insolvency. The study concludes with recommendations for guiding Sri Lanka and similar vulnerable economies toward sustainable recovery, emphasizing the need to strengthen economic fundamentals, foster innovation, and enhance resilience against future shocks.
