Expression in Josef Matthias Hauer’s piano music as exemplified by Klavierstücke mit Überschriften nach Worten von Friedrich Hölderlin Op. 25
Authors: Barwinek Bartłomiej 
Published: August 2024

Abstract
Austrian composer Josef Matthias Hauer (1883–1959) went down in history as one of the leading figures of atonal music in the first half of the 20th century and the creator of an original—different from Schönberg’s—conception of twelve--tone technique. Although the principles of dodecaphony developed by the author of Nomos Op. 19 differ significantly from those established by the founder of the Second Viennese School, the most striking thing for the listener is the difference in the expressive sphere that occurs between pieces of both composers.
Fundamental to the issues of Hauer’s form and characteristic poetics is his aesthetic world view, which sets as the goal of his artistic work the idea of spiritual perfection, inspired among others by an esoteric interpretation of Johann Wolfgang Goethe’s beliefs.
The Klavierstücke Op. 25 discussed in this article allows—at least in part—for a more careful reading of this peculiar philosophy, thanks to a guide suggested by the composer himself, namely the poetry of Friedrich Hölderlin (1770–1843). Through the prism of its short fragments, which constitute the mottoes of the fourteen piano miniatures, we can come closer to justifying and explaining the expressive categories adopted by the composer.
The author analyses the expressive sphere of the work, considering its individual elements within three successive layers of expression: 1) an external one— reflected in the notational convention of the work, 2) an indirect one—concerning the historical and stylistic context, and 3) an internal one—encompassing the space of meaning and narration.
Mahler and the Taking Back of the Ninth
Authors: Berger Karol 
Published: August 2024

Abstract
The last word of Mahler’s Fifth Symphony, composed in 1901–02 and premiered in 1904, is ironic, mocking even, certainly not pompously triumphant. What is mocked here is the whole tradition of victorious symphonic scenarios epitomized by Beethoven’s Ninth Symphony, the “per aspera ad astra” tradition that had symphonists propose stories of suffering triumphantly overcome. The Finale also puts into question Mahler’s own past. For the first time, the composer writes here a symphony that does not aim at a transcendence and sublimity, but accepts the comic immanence of the earthly existence. The aspiration to transcendence fails, but is not forgotten, and neither are the negative aspects of human existence that gave rise to this aspiration
Four musical settings of the poem “In Danzig” by Joseph Eichendorff — music and the expression of the word
Authors: Schiller-Rydzewska Joanna 
Published: August 2024

Abstract
The poem In Danzig by Joseph Eichendorff, which appeared in the second edition of his works collected in 1848, is one of the most famous and important poems of the 19th century about Gdańsk. Its author, an important German poet of the Romantic era, has visited Gdańsk three times. From 1821 to 1824 he lived and worked here for the first time as a Prussian civil servant. In 1838, he spent several weeks in Gdańsk with his eldest daughter. The last time he spent in the city was in the years 1843–47 and lived with his family on Chlebnicka Street. At that time a poem was probably written in 1843 with the original title Nachts, later changed to Nachts in Danzig, finally entitled In Danzig.
This outstanding example of German romantic poetry proved to be an important source of inspiration for the work of composers of different formats. The most well-known example of the song based on the poem comes from the work of Hans Pfitzner, the German composer of the turn of XIX/XX. I also noticed two other works on the Eichendorff text by lesser-known composers during the inquiry in the Gdańsk Library: Max Stange and Alfred Balfanz. The latter was Gdańsks citizen. The immediate impetus for dealing with this problem was the work of the young composer Kamil Cieślik with the eponymous title, which was premiered by the Gdańsk Vocal Ensemble Art’n’Voices.
The object of the proposed reflection is therefore an attempt to compare the characteristics of the musical layer of the four works with regard to the expression of the poetic layer of Eichendorff’s poem. The thesis, which emerges in the initial stage of observation, follows intuition: the clarifications of the poem acquire a universal form to a certain extent. This means that the expression of the word in the works depicted is of utmost importance for the music.

Public Debt and Economic Growth in Nigeria: A Consideration of New Evidence
Authors: Onyenwife Kingsley C. , Ezeanyeji Clement I. , Ekesiobi Chukwunonso 
Published: August 2024

Abstract
The discussion surrounding the connection between public borrowing and economic expansion has persistently endured without abating. While debt desirability proponents argue that public debt is growth-enhancing, others argue that public debt does more harm than good to the economy. In recent times, the increase in public debt in Nigeria continues to raise concerns regarding its desirability. Although several studies have been carried out in this regard, there is hardly any study that examines the public debt-growth nexus in the context of the tradable and non-tradable sectors. Second, there is hardly any study that disaggregates bank-sourced debt from non-bank-sourced debt. Thus, the study aimed to achieve two-pronged research objectives: To appraise the implications of public debt on the economic growth in the tradable sector of the Nigerian economy and to analyze the effect of public debt on the economic growth in Nigeria’s nontradable sector. This study spans from 1981 to 2020. Using the Generalized Linear Model (GLM), the following conclusions are made. Initially, different elements of public debt have varying impacts on the growth of the tradeable sector. External debt and debt obtained from non-bank sources positively drive the growth of the tradable sector. However, debt acquired from banks and the associated servicing costs hurt the growth of the tradeable sector. Furthermore, the different components of public debt have varying impacts on the growth of the non-tradable sector. Specifically, foreign debt and debt obtained from non-bank sources have a significant positive influence on the growth of the non-tradable sector. The influence of debt acquired from banks on the nontradable sector is positive but insignificant. However, similar to the tradable sector, the servicing of debt undermines the growth of the non-tradable sector. Policy insights were provided in line with the study’s findings.
A Novel Assessment of the Growth-Inequality Nexus in East-Central Europe
Authors: Pop Teodora M. 
Published: August 2024

Abstract
Abstrac
This paper investigates the nexus between economic growth and income inequality by exploring a sample of 11 Central and Eastern European (CEE) emerging countries from 2000 to 2019. The existing theory argues for three different situations that may appear: a positive link between economic growth and inequality, a negative association or a non-linear relationship. Generally, by employing a fixed-effects model that is robust to heteroskedasticity, cross-sectional dependence and autocorrelation, our findings reveal a significant non-linear growth-inequality connection, in accordance with Kuznets inverted U-shaped hypothesis. Additionally, we find that several transmission channels considerably influence this relationship in the CEE group, including poverty, educational attainment and trade openness. Our results denote a positive impact of international trade and human capital investment on reducing income inequality, emphasizing that an increase in the share of the population with tertiary education and trade openness will lead to a decrease in the Gini coefficient. Moreover, by improving the correlation between labour market requirements and the educational attainment of the population and adopting efficient poverty-reduction strategies, sustainable economic growth may mitigate the adverse influence of inequality in the long term. Therefore, policymakers should pay attention not only to the general macroeconomic framework of these countries but also to the implications of the socioeconomic dimension of inequality to reduce existing income disparities.
Decoding the Business Model: A Comparative Analysis with Strategy and Planning, and a New Seven-Keys Framework to Formulate A Business Idea
Authors: Todorova Ana , Pavlov Daniel 
Published: August 2024

Abstract
The article studies business models and their essence, comparing them to business plans and strategies. Various definitions and characteristics of business models are examined to be better understood and applied, both from a theoretical and a practical point of view. The aim is not to deny existing theoretical positions regarding business models but to suggest a new perspective where it is permissible, adapt existing knowledge to new business realities and opportunities and present an effective process for developing a business model. Through an in-depth content analysis of articles and reports published in renowned journals and conferences, multiple definitions of different researchers are given, and weaknesses in the interpretations are sought, but without challenging the existing paradigms. The systematic literature review found that the business model is applied with a much higher priority in practice than the business plan and strategy and enjoys significant interest from researchers. A major credit for this is its comprehensiveness in describing the design, structure and management of creating value by exploiting business opportunities. Our findings show that in academic and business circles, there is no clear enough distinction between business model, business plan and business strategy. Based on these findings, we present theoretical and applied guidelines and an innovative seven-keys framework for elaborating a business model.

Published: August 2024

The radial distribution network system is an important part of the electric power system because this distribution system is useful for distributing electricity to loads (customers). the existence of voltage drops and electric power losses in the provision of electrical energy is something that cannot be avoided. There are several ways that can be done to improve voltage, one of which is the installation of Shunt capacitors in the primary distribution network. Voltage drop can occur in the power system due to the loss of voltage stability in the radial distribution network. This study analyzes the value of voltage stability index in 33-bus IEEE and 69-bus IEEE with current injection method power flow analysis. In the 33-bus IEEE system, the existing condition obtained the minimum bus voltage of 0.9131 pu or 11.560 kV occurs at bus-18. By installing 2 units of shunt capacitors in the 33-bus IEEE system, it can minimize active power losses from 202.464 kW to 157.153 kW or by 22.38%. In the existing 69-bus IEEE system, the minimum bus voltage of 0.9092 pu or 11.511 kV occurs at bus-65. With the installation of 1 unit of shunt capacitor, the voltage at the installation of 3 units of shunt capacitors, the voltage at bus-65 is 0.9514 pu or 12.045 kV, which has increased by 0.534 kV. By installing 3 units of shunt capacitors in the 69-bus IEEE system, it can minimize active power losses from 224.698 kW to 22.994 kW or by 5.21%..

The Sexual Violence Criminal Law (TPKS Law) in Preserving the Family in The Maqasid Sharia Perspective
Authors: Suwarjin Suwarjin , Shairgojri Aadil Ahmad 
Published: August 2024

This study aims to unveil the manifestations of sexual violence in Bengkulu and subsequently elucidate the significance of the Sexual Violence Law in safeguarding families through the lens of Maqasid Sharia. Employing a qualitative library research methodology with a normative-conceptual approach, the investigation reveals two main findings. First, the ratification of the Sexual Violence Law signifies a legal stride to address and protect victims, filling a void in specific legislative provisions. Notably, Bengkulu ranks fourth in sexual violence cases within Sumatra, with perpetrators predominantly known to the victims. However, the region lacks comprehensive psychosocial support, including educational aid, psychological services, reproductive health examinations, and talent development opportunities for child victims. The absence of secure shelters compels social workers to resort to orphanages as an alternative. Second, the urgency of the Sexual Violence Law, viewed through the Maqasid Sharia perspective, aligns with the dharuriyat level, emphasizing the protection of religion (Hifz al-Diin), safeguarding the body and soul (Hifz al-Nafs), ensuring mental well-being (Hifz al-‘aql), and protecting offspring (Hifz al-Nasl). This study sheds light on the necessity of legal provisions in mitigating sexual violence while emphasizing the broader societal and familial dimensions from a Maqasid Sharia standpoint.

Authors: Mubarok Husni , Jamil M. , Syahputera Akmaluddin 
Published: August 2024

The implementation of self-circumcision in Indonesia was sheltered by the government, in this case, the Ministry of Health, in 2010 with the issuance of Regulation of the Minister of Health of the Republic of Indonesia Number 1636/MENKES/PER/XI/ 2010 concerning Female Circumcision. Problems arose when the 2010 rule was repeated in 2014, resulting in discomfort among the people of Marbau District, North Labuhanbatu Regency. This study will analyze the enlightenment of the theory of legal certainty, maqashid asy-syari'ah, regarding Circumcision in the Regulation of the Minister of Health of the Republic of Indonesia Number 6 of 2014 in Marbau District, North Labuhanbatu Regency. The research method used the library (library research) and (empirical research). The Primary sources are observations, interviews, and Regulations of the Minister of Health in 2010 and 2014. The research results show that in terms of legal certainty theory, the Law is made so that it can be implemented by the community, while The 2014 repeal regulation is uncertain because it is difficult to implement. In the maqashid asy-shari'ah aspect, Circumcision is part of religious care (hifzud din), on the other hand, it does not mean that in the practice of Circumcision, harming girls or neglecting to protect oneself or one's soul (hifzhun nafs), but for the sake of giving obedience, and it is useful to control the lust of a girl when she grows up.
Legal Analysis of Islamic Economic Law on Hybrid Contracts in Islamic Financial Institution Products
Authors: Niffilayani Anita , Thao Le Thi 
Published: August 2024

This article is intended to philosophically analyze the existence of hybrid contracts or al-’uqûd al-murakkabah (complex contracts) or multi-contracts. The research focuses on the opinions of hadith scholars and fiqh muamalah (Islamic commercial jurisprudence), as well as their applications in Islamic financial institutions. This is crucial because a single contract form cannot adequately respond to the current financial conditions. Transactions are always dynamic and influenced by the financial industry at national, regional, and international levels. This research is a qualitative-literature study with a philosophical-normative approach. It analyzes the hadith texts and scholars' views philosophically, then juxtaposes the ideal-philosophical aspect with the reality in Islamic banking. The study concludes that, first, the Sharia economic law analysis of hadith related to the hybrid contract model explains the prohibition of bai’ataini fi bai’atin (two sales and purchases in one), the prohibition of shafqataini fi shafqatin (two agreements in one), and the prohibition of bay' and salaf (sales agreement and advance payment for goods). Second, the construction of the hybrid model in Islamic banking aims to develop al-’uqûd al-mutaqâbilah (conditional contracts) and al-’uqûd al-Mujtami’ah (similar contracts), implemented in housing financing.
The Applicability of Leasing Contracts in Islamic Law Perspective to Enhance the Economic Growth in Indonesia
Authors: Jalili Ismail 
Published: August 2024

The lease finance contract plays a significant role in contemporary financial operations in Indonesia. However, the lease contract must adhere to Islamic law and government regulations in order to promote the reliability of leasing within society and among business participants. The purpose of this study was to analyze the compliance of leasing practices in Indonesia to Islamic law and regulatory standards, as well as to evaluate the level of compliance and protection provided by legal provisions in leasing contracts for small and medium-sized businesses operating in the home industry sector in Indonesia. This study employs a qualitative analytical method based on the application of a statutory and conceptual approach to data description and analysis. The results show that the leasing activities carried out by business entities in Indonesia are conducted in compliance with the principles of Islamic law and the regulations set by the government. Leasing has demonstrated its significant role in fostering economic expansion and augmenting state revenue. Nevertheless, it is anticipated that the government will assume a more proactive role in enhancing consumer protection and ensuring efficient oversight, so ensuring that leasing practices adhere to current legal regulations
