Pengaruh Penerapan Sistem Informasi Akuntansi, dan Sistem Pengendalian Internal terhadap Kualitas Laporan Keuangan dengan Kompetensi Sumber Daya Manusia sebagai Variabel Moderasi
Authors: Aurelia Zarah Kamandita  , Suwandi Suwandi
Published: January 2025

This study aims to analyze the influence of the application of Accounting Information Systems (AIS), Internal Control Systems (ICS), and Human Resource Competence (HRC) on the quality of financial statements, with HRC as a moderating variable. The research was conducted on financial department employees at Eyelink Group using a quantitative approach and Partial Least Squares (PLS) analysis technique. The findings reveal that AIS and ICS do not have a significant direct impact on the quality of financial statements. However, HRC significantly affects the quality of financial statements. HRC also strengthens the relationship between AIS and the quality of financial statements but does not significantly moderate the relationship between ICS and the quality of financial statements. These findings underscore the importance of competent human resource management to support optimal AIS implementation and improve the quality of financial statements. The study recommends the development of human resource competence through continuous training and education as a strategic measure to enhance financial reporting quality.
Un elegante senso di disgusto. Mappatura visuale del mannequin nella fotografia di moda
Authors: Bruccoleri Doriana
Published: January 2025

The mannequin is a paradoxical figure, simultaneously captivating and disturbing. Within this ambiguity, the Surrealists explored the boundary between the animate and the inani- mate in search of that uncanniness that aligns with Freud’s concept of the Das Unheimli- che. This study investigates the peculiar sensation of disgust and repulsion provoked by this human simulacrum in surrealist fashion photography. The analysis is structured as a visual mapping of the mannequin, examining photographs published in Vogue between 1925 and 1945.
The investigation reflects on the concept of disgust, here framed within Freud’s notion of the uncanny and interwoven with the Surrealist concept of convulsive beauty, tracing back to the Surrealists’ critique of capitalism, of which the mannequin becomes a vehicle. A comparison with Hans Bellmer’s explicitly disturbing Poupée highlights the polished perfection of the mannequins staged in fashion editorials by photographers such as Man Ray, Horst, Hoyningen-Huene, and Blumenfeld. Drawing upon theories of psychoanaly- sis, aesthetics, and art history, the study examines the factors that render these images disturbing: their artificiality, lifelessness, and resemblance to the human form. However, the Surrealist operation has a subversive edge: discomfort serves to reveal the circular relationship between art and consumerism.
The visual trope of the mannequin, with its intrinsic duality of elegance and the abject, serves as a lens through which to examine this subtle undercurrent of unconscious disgust that permeates surrealist fashion photography, pushing the boundaries of artistic expres- sion and critique of modern society.
Hungary: Tax Competition Á La Hungary: Tax the Turnover and Relinquish the Income
Authors: Károlyi Balázs
Published: January 2025

This chapter delves into the most recent issues of fiscal sovereignty regarding the Hungarian direct tax system. It highlights the actual and potential conflicts between domestic corporate tax rules (including not only corporate income tax provisions but also other types of special taxes) and primary and secondary EU law. In respect to clashes with primary EU law, this chapter explores the recent case law of the Court of Justice of the European Union in light of the fundamental freedoms and the EU Charter. Furthermore, regarding secondary EU law, this chapter considers the compatibility of domestic rules with the anti-avoidance directives as well as with the global minimum tax directive and argues that a proliferation of similar conflicts can be expected across the EU due to the peculiar nature and inherent mechanisms of the relevant directives.
Poland: Tax Law and Policy in Poland : Bold and Expected Changes
Authors: Oktaba Robert
Published: January 2025

This publication addresses the issues related to the concept and processes of the coexistence of tax harmonisation in the EU and the sovereign tax policies of individual Member States. An important task in the context of the creation and application of EU tax law regulations is determining the tax sovereignty of Member States and the legitimacy of implementing an autonomous tax policy adapted to the current social and economic needs of a given country. These phenomena also affect the tax competitiveness of a given country in the international arena. Importantly, implementing a sovereign tax policy allows state authorities to take flexible actions to counteract tax avoidance and combat tax fraud in a given country. Thus, eliminating unfair competition from the market strengthens the position of law-abiding taxpayers. Moreover, this interdependence contributes to economic growth and employment opportunities. As a result, it is possible to increase tax revenues from the taxation of both the growing economic turnover and the income of natural persons and entrepreneurs. Therefore, the possibility of implementing a sovereign tax policy allows for the creation and maintenance of a tight and functional tax system, which is a key element of economic and social order. It is worth emphasizing here that macroeconomic data, both domestic and international, indicate that Poland’s sovereign tax policy has yielded excellent results over the last seven to eight years.
Romania: The Relationship Between Tax Legislation, Tax Competition, and Sovereignty
Authors: Cîrmaciu Diana
Published: January 2025

Dealing with a topic related to taxation involves engaging complex issues, both in terms of incidental legislation and its role (i.e. its economic and social functions). The state plays a decisive role in economic development, but its intervention in this field must not have a restrictive character, evident in the adoption of rigid – and sometimes even arbitrary – legal provisions. Interventions in the economy, which have a long history, are done naturally according to emerging needs, assuming the implementation of a predictable fiscal policy to adapt the business environment to the challenges of the contemporary period (e.g. economic crises, health crises, armed conflicts). When, for various reasons, economic values are overturned, reform is necessary to bring the economic sphere into harmony with legal norms, which must then be recovered and developed. In light of these ideas, this study briefly analyses the state of fiscal legislation in Romania and clarifies related technical terms and definitions. We follow the trends in Romanian taxation, the fiscal policies which the governors assume, and the measures to ensure budget revenue (these measures are not always popular, but are arranged for the benefit of the general interests of the community). The field of taxation often raises problems, and such analyses can yield ways to implement combinations of taxes that enable public authorities to cover budgetary needs (taking into account the nation’s level of development and specific economic features).

Poland: Monetary Policy Still Outside the Eurozone
Authors: Mikos-Sitek Agnieszka
Published: January 2025

Poland is an EU Member State that has not adopted the single currency status and remains outside the Eurozone. It has also not yet joined the European Banking Union based on the so-called ‘close cooperation’. In the European integration process, numerous measures were taken to align Polish legal solutions in the banking field with European Union regulations. Among other things, the introduced changes concerned the functioning of the central bank of the state and led to its inclusion in the single monetary and currency policy of the European System of Central Banks. Despite growing expectations in recent years that Poland will soon adopt the euro, Poland has not taken decisive steps in this regard due to its ambiguous assessment of the benefits and possible risks involved. It should also be noted that Poland’s accession to the Euro area is not currently possible because of its insufficient fulfilment of the convergence criteria. Further, Poland’s decision to function in the euro area is complicated by the specific predispositions of the Polish banking sector as well as by the uncertain timeline for adopting a single currency due to the ongoing economic crisis.
Slovakia: The Path From Monetary Sovereign to Common European Rules
Authors: Štrkolec Miroslav
Published: January 2025

This chapter focuses on the monetary policy of Slovakia, a member of both the EU and the Eurozone. Slovakia’s membership in the euro area has fundamentally influenced, and continues to influence, its monetary policy. From the Slovak perspective, we distinguish between the period up to 2009, when the Slovak Republic – represented by the National Bank of Slovakia (NBS) – was the monetary sovereign, and the period from 2009 onwards, when the NBS participated in the common monetary policy set by the European Central Bank for the entire Eurozone. In the introduction, we highlight the historical background of Slovakia’s entry into the euro area in terms of its fulfilment of the convergence criteria. We also discuss the advantages and disadvantages of Eurozone membership in terms of assumptions and subsequent realities. The bulk of this chapter deals with the European Banking Union from the perspective of Slovakia, which, as a member of the Eurozone, is obliged to participate in its existing pillars. It takes a closer look at the powers entrusted to the national authorities (NBS, Resolution Board, Deposit Guarantee Fund) to achieve the objectives for which the banking union was created. Finally, the chapter concludes by highlighting Slovakia’s limited influence on the European Union’s monetary policy, in which it participates mainly through the NBS governor in the Governing Council of the European Central Bank.
The Role of Values: A Study of Female Heroes in Chinese and American Movies
Authors: Yang Kexin
Published: January 2025

Hero is a figure who embodies the national spirit and represents the values and spirit of a nation. With the development of film production, there has been a notable increase in the number of people who have focused their attention on female heroes. This paper employs Hofstadter's dimension framework to elucidate the distinctions between female heroes in Chinese and American movies. In order to facilitate a comparative analysis of the portrayal of female heroes in Chinese and American movies, four war-themed movies were selected for this study. Ultimately, it is found that values exert the greatest influence on individualism, Collectivism, Masculinity, Femininity and power distance. Concurrently, as bilateral exchanges between China and the United States become more profound, there is also a mutual influence on each other in terms of values. The research of Chinese and American cultures of heroism also creates more space for individuals to reflect on life and society later and to preach heroism in the contemporary era

Authors: Liu Yubo
Published: January 2025

The banking sector is fiercely competitive in the present difficult time. Banks concentrate on both customer retention and customer turnover to raise the caliber and degree of service. The classification issue in the banking sector is examined in this essay. It detects possible churners from among potential customers and primarily focuses on bank customers' worries around churn. The bank uses supervised machine learning to identify and forecast which of its clients are most likely to leave. Since it is necessary to define churn and non-churn clients, customer churn prediction can be used in this situation. To address the distinctions between churn and non-churn clients, this study uses logistic regression, decision trees, and random forest classifiers. Accuracy levels can be attained via several classifiers. The Kaggle dataset for bank customer churn modeling is used for the experiment. To identify an appropriate model with more accuracy and predictability, the outcomes are compared. The findings demonstrate that, upon oversampling, in terms of accuracy, the decision tree model outperforms other models.

Authors: Zhang Zidong
Published: January 2025

The paper mainly focuses on predicting the customer churn rate by using Machine learning models. The customer churn rate becomes a serious problem because of the competitive market. Many companies care about the number of customer rates because the company wants to retain the current customers to let the current customers buy the companys product and service. In addition, the cost of retaining an existing customer is lower than the cost of acquiring new customers. That means lots of telecommunication companies want to lower the customer attrition rate to make the company more beneficial. To find the attrition rate, companies must find the data and use models to analyze the data. The paper will use several models to analyze the data from Kaggle and find which models are better for analyzing the attrition rate by using Python. It will include several steps to analyze the data: Exploratory Data Analysis, Feature Engineering, Feature Selection, Model Tuning, Stacking model, and Final analysis and results. Lastly, the result showed that these models dont overfit and it concluded that the logistic regression with the upsampling method is better than other models.

Unveiling Humanity’s Dilemma: A Critical Analysis of Morality and Compassion in John Boyne’s “The Boy in the Striped Pyjamas”
Authors: Mary R Priskilla , Priya N. S. Vishnu
Published: January 2025

Humanity, often defined as the epitome of benevolence within the human race, reflects a profound essence of compassion and empathy towards fellow beings. Echoing Leo Tolstoy's assertion that "The sole meaning of life is to serve Humanity," this paper delves into an exploration of humanity's mere existence within the human race. Amidst the devastating tumult of the two Great World Wars, humanity's essence came under intense scrutiny, particularly during the dark shadows of World War II. At the heart of this catastrophic event lay the seeds of destruction sown by an individual, the notorious dictator, Adolf Hitler, whose descent into moral decay stripped him of his once-human traits and compassionate nature. John Boyne's poignant novel, "The Boy in the Striped Pyjamas," vividly portrays the horrors perpetuated by Hitler's principles and dictatorship during the Holocaust. The novel painfully depicts the plight of innocent groups, notably the Jewish community, who tragically fell victim to the inhumanity of Hitler's regime. Through the lens of psychological turmoil amidst the Holocaust, the novel also sheds light on the internal conflicts within the Nazi family, whose stringent adherence to ideological boundaries left no room for humane exceptions. The harrowing experiences of the innocent protagonist, Bruno, and his friend Shmuel, serve as a poignant reminder of the tragic consequences that ensued, ultimately claiming their lives in the brutal throes of the Holocaust. Bruno's innocence serves as a lens through which the reader grapples with the moral implications of the Holocaust and the dehumanization of the Jewish community. The Boy in the Striped Pyjamas, delineates the incidents that took place during Hitler's rule which were analyzed from the perspective of Social Identity Theory. The story clearly portrays how the Nazi beliefs made it very easy for them to create a social categorization of themselves and others (the Jews) and how they internalized their norms, values, and behaviors as a socially desired group. The analysis of the themes of the novel shows that the relationship between ‘Bruno – and Shmuel’ does not have these socially imposed barriers because made them victims of the society which is quite sad – especially for the nation's histories which experienced such divisions.

Authors: Sanosi Abdulaziz B , Nur Hala S , Arafat Yasir , Muhammad Dikko
Published: January 2025

The syllabus design for ESP should account for specific learners’ and industry needs regarding language skills, aspects and functions. Furthermore, the process should consider the globally trending challenges to prepare learners for their prospective jobs. In this regard, UN Sustainable Development Goals (SDGs) are comprehensive agenda that shapes the world's future in different interconnected domains. Thus, incorporating them in ESP syllabi can promote knowledge about Sustainable Development (SD) as suggested by UN SDG 4 on Quality Education and contribute to the achievement of other goals, such as UN SDG 8 on Decent Work and Economic Growth. Subsequently, the present study adopts the Delphi technique to explore 23 multinational and multidisciplinary experts on the ways to develop a needs-analysis-based tourism ESP syllabus that promotes the UN SDGs and enables learners to effectively communicate them in their future careers. The results show that although the current syllabus is aligned with target learners' needs and the specified goals, it lacks appropriate alignment with UN SDGs and sustainable tourism. The experts recommend updating learning goals and outcomes to align the syllabus with the UN SDGS and enrich it with more SD-related content. The study's implications highlight the need for further research on adapting ESP syllabi across disciplines to address globally trending issues and initiatives outlined in the UN SDG framework.

As culturas de inverno apresentam um alto potencial para a produção de forragens, as quais respondem a diferentes estratégias de cortes, surgindo a necessidade de desenvolvimento de pesquisas para determinar o melhor o número de cortes aliados a uma boa produção. O sistema de consórcios de gramíneas ainda é pouco estudado. Este trabalho teve como objetivo avaliar as características produtivas e bromatológicas de forrageiras hibernais submetidas a seis cortes sucessivos. Foram utilizados diferentes forrageias hibernais cultivadas em consórcio ou solteira, conforme designação dos tratamentos: TamPic: 90% de aveia branca GMX Tambo + 10% de aveia preta GMX Picasso; InvPicGau: 90% de aveia branca GMX Invernia + 5% de aveia preta GMX Picasso + 5% de aveia branca UPF Gaudéria; TamGau: 30% de aveia branca GMX Tambo + 70% de aveia branca UPF Gaudéria e Pic: 100% de aveia preta GMX Picasso. No quinto corte, o consórcio de aveias permitiu maior participação de folhas e menor participação de colmos na composição morfológica da planta em relação à aveia preta cultivada solteira (Pic). Os teores de fibra em detergente neutro e de fibra em detergente ácido foram menores para o cultivo das aveias em consórcio, que variaram de (48,09% a 51,40% e 32,29% a 34,39% respectivamente) frente ao cultivo solteiro (54,84% e 38,32% respectivamente). A degradação ruminal das forragens consorciadas foi superior ao cultivo solteiro. Em relação aos cortes, o sexto corte apresentou os piores resultados para os teores de fibra e degradação ruminal. Recomenda-se o consórcio das aveias avaliadas, visto que apresentaram características morfológicas e químicas satisfatórias, e até o quinto corte melhor composição química e maior degradação ruminal da forragem, o que mostra potencial do ponto de vista nutricional.

An ideal impression material should present with dimensional stability over long periods, allowing the precise production of cast models at any time. However, the materials commonly used in dental impressions present alterations in their dimensional behavior. This study amid to evaluates the effect of the Impression technique, Single step, two steps, and Impression pouring time on the dimensional accuracy of two different impression materials; polyvinyl siloxane impression material, and polyether impression material, using Cone Beam Computed Tomography (CBCT) analysis. Two commercially available impression materials were used in this study Polyvinyl siloxane (PVS)- Polyether (PE),30 standardized metal custom-made dies representing full veneer all ceramic crown preparation, and 30 perforated custom-made trays fabricated that be placed in the same position on the master die for each impression, each material divided into two groups each group (n 15)one group using two-step technique the other group one step technique For each group, specimens were subdivided according to the pouring time into three subgroups (5 samples); 1hour, 24hour, 7days. All samples submitted for CBCT for evaluation of their dimensions. There were no significant differences with PVS and PE, but the single step showed a significant difference in highest mean high compared to two steps. 1 hr. (4.96±0.01 μm) showed an insignificant difference on mean height compared to 24 hours (4.96±0.01 μm) and 7 days (4.90±0.01 μm) at p=0.791 for Single step.1 hr (4.86±0.01 μm) showed insignificant difference on mean height compared to 24 hours (4.85±0.01 μm) and 7 days (4.81±0.01 μm) at p=0.960 for Two steps for PVS. 1 hr (4.95±0.03 μm) showed insignificant difference on mean height compared to 24 hours (4.94±0.01 μm) and 7 days (4.89±0.01 μm) at p=0.100 for Single step. 24 hours (4.85±0.02 μm) showed significant difference on mean height compared to 1 hr (4.84±0.01 μm) and 7 days (4.80±0.01 μm) at p≤0.001 for two steps for PE. Polyvinyl siloxane and poly ether materials give high accurate stone dies. One-step impression taking technique give more accurate stone dies than the two-step technique. pouring time is very critical for PE impression materials.

Background:
Gram-negative bacteria are increasingly associated with severe infections due to the emergence of antibiotic resistance mechanisms, including Extended-Spectrum Beta-Lactamases (ESBLs) and Metallo-Beta-Lactamases (MBLs). Understanding the prevalence of these enzymes is crucial for effective infection control.

Aim:
To determine the prevalence of ESBL and MBL producing Gram-negative bacteria in clinical samples, investigate their co-expression, and analyze antibiotic susceptibility patterns to inform optimal antimicrobial stewardship and infection control strategies.

Methods:
This observational study was conducted at a rural tertiary care hospital in India, and spanned one year. Clinical samples were cultured and identified. Gram-negative isolates underwent susceptibility testing following CLSI guidelines. Furthermore, Double Disc Synergy Test (DDST) and modified Carbapenem Inactivation Method (mCIM) were utilised for phenotypic detection of ESBL and MBL production, respectively. Subsequently, the data on antibiotic susceptibility and resistance prevalence were analysed.

Results:
Among Gram-negative isolates, ESBLs were detected in 41.8%, while MBLs were found in 23.4%, with 7.4% co-expressing both enzymes. Escherichia coli and Klebsiella pneumoniae were the predominant ESBL and MBL producers. Colistin showed high susceptibility (95.5%). However, significant resistance to levofloxacin was observed. Notably, resistant organisms were isolated from both inpatients and outpatients.

Conclusion:
This study highlights the alarming prevalence of ESBL and MBL producing Gram-negative bacteria, particularly E. coli and Klebsiella spp., in a hospital setting. While colistin showed promising activity, the emergence of resistance in outpatient samples emphasizes the need for stringent infection control measures and judicious antibiotic use.
