The Crawling Ban of the Labor Day Celebration in the Age of Indonesian Transition, 1966-1968
Authors: FX Domini BB Hera  , Ari Sapto  , Daya Negri Wijaya
Published: January 2025

The dynamics of labor movements in Indonesia 1966 were shaped by the broader political and economic transformations that followed the 1965 coup attempt. The transition to Suharto's New Order regime brought about significant changes in labor relations, characterized by the suppression of independent unions and the prioritization of economic recovery over labor rights. This study used historical methods using archival primary sources and contemporaneous narratives. This research will reveal the dynamics of labor day in Indonesia in 1966-1988 as well as Indonesian politics in a historical perspective during. This research shows that Labor Day celebrations are embedded in Indonesian society. The new ruler did not easily erase the tradition of Labor Day celebrations. The abolition of Labor Day could happen after 2 years, which means 2 times the celebration was still held despite being under pressure. The celebration of Labor Day was eventually resumed illegally, but openly in 1995 (as a protest against the then regime). Post-authoritarian 1999 and since 2013, Labor Day has been declared a public national holiday by the Indonesian government.

From the results of the analysis and discussion that Bank BTN Persero is a good faith creditor in granting credit, and has been in accordance with standard operating procedures, and has not violated the laws and regulations, canceled Mortgage Rights by Court Decision does not cause the Debtor's debt to be canceled, the Creditor can take legal action for Wrongful Acts to request compensation for the actions that have been caused and request other assets / assets in exchange for Mortgage Rights that have been canceled previously by Court Decision.
Trademark Sales Study as Boedel Bankrupt by the Curator
Authors: Aldy Wicaksono  , Ahmad Sudiro
Published: January 2025

Trademarks are included in the Intellectual Property Rights (IPR) regime in Indonesia because trademark rights are always attached to economic rights. This study uses a normative method by collecting secondary data. Qualitative analysis was carried out on secondary data to obtain conclusions about the Nyonya Meneer brand as an intangible asset owned by PT Nyonya Meneer which is bankrupt based on the Commercial Court Decision. As a result of the law of PT Nyonya Meneer being bankrupt, the Curator carried out the settlement and management of the bankrupt estate including the Nyonya Meneer brand by auction through private sales with an appraisal value of Rp. 200 billion to Rp. 10.25 billion. It is hoped that the government will make a regulation related to the valuation regulations for IPR as well as regulations related to the transfer of IPR as bankrupt assets and create a special appraisal institution to provide legal certainty for the curator in carrying out his duties and authorities.
Legal Review of Land Certificates Affected by Forest Areas in Indonesia
Authors: Marisyah Taher  , Gunawan Djajaputra
Published: January 2025

This research examines the legal review of land certificates affected by forest areas according to the Indonesian Basic Agrarian Law (UUPA) and its implications within forest regions. Under the UUPA, land encompasses not only the surface but also the subsoil, establishing legal relationships between individuals or legal entities and the land, which results in specific legal statuses. The UUPA regulates land rights, including permanent rights, statutory rights, and temporary rights. Land registration is mandated to ensure legal certainty for rights holders and to provide protection by issuing valid certificates. These certificates serve as strong evidence of ownership, though they can be annulled if administrative or material errors are found. In the context of forest areas, land regulation becomes more complex. Forest areas, as stipulated by the Forestry Law, require protection and must be exempt from individual or corporate rights, as such rights can threaten the sustainability of forest ecosystems. To address land ownership conflicts within forest regions, the government has issued Presidential Regulations that govern the processes for managing, organizing, and resolving disputes in forest areas through various mechanisms, including social forestry programs. Agrarian reform is also implemented through land redistribution to promote welfare and equity. However, despite regulations governing certificates within forest areas, no specific policy exists regarding the annulment of certificates in these zones. Annulment is needed as a legal remedy for ownership disputes that may arise due to administrative defects or illegality

Published: January 2025

The objective of this research is to understand and analyze the legislative ratio regarding the age restriction provisions for children of female inmates in women's correctional facilities under Article 62 paragraph (1) of Law Number 22 of 2022 on Corrections. The method used in this research is normative legal research. The results of this research indicate that the rights of young children of female inmates are not fully guaranteed within the existing legal framework. The regulation of this legal protection is still not optimal in determining the age limit for children of female inmates. This research proposes improvements in the policy of age restriction in legal protection for young children of female inmates and contributes to a better understanding of the age restrictions in legal protection for young children of female inmates in correctional facilities.
Legal Analysis, Default in Land Sale and Purchase (Case Study of Decision Number 119/Pdt.G/2024/PN Palangkaraya and Its Implications for Consumer Protection)
Authors: Frima Klin  , Andika Wijaya  , Ivans Januardy
Published: January 2025

This study aims to analyze the application of civil law related to default in land sale and purchase through a case study of Decision No. 119/Pdt.G/2024/PN Palangkaraya. This study uses a normative legal method with a case study approach, where the primary data used are court decisions and secondary data in the form of laws and regulations and related legal literature. The main findings of this study indicate that the defendant has committed default by not fulfilling his obligations in changing the name of the Land Ownership Certificate, which resulted in losses for the plaintiff. The court decided to grant the plaintiff the right to take care of the name change independently, thus providing effective legal protection for consumers. The contribution of this study lies in an in-depth analysis of the implications of the decision on consumer protection in land sale and purchase transactions. This study enriches the discourse on consumer protection by highlighting the importance of strong law enforcement and simpler administrative procedures to prevent similar disputes in the future. In addition, this study provides a new perspective on the court's role in strengthening consumer legal protection in land disputes.

Authors: Sithole-Tetani Ntombophelo
Published: January 2025

The 2030 Agenda for Sustainable Development, as it is known, is a call to action to end poverty, protect the planet, and ensure prosperity for all. The third SDG, ‘Good Health and Wellbeing,’ aims to ensure healthy lives, promote well-being for all ages, and halt and reverse global illnesses such as HIV, tuberculosis, and the COVID-19 pandemic, etc. This paper used a narrative literature review to discuss the role of psychology in SDG3 in the South African Context. A narrative literature review is an extensive joining and assimilation of existing research on a specific issue, providing an overview of major discoveries and their interconnectedness. Findings revealed that despite the significant contributions that can be made by psychology, the barriers to integrating psychology into health systems are as complex as applying a psychological approach to achieving sustainable health outcomes. Barriers are recognized, and their resolution is facilitated within the context of social justice and human rights; the significant roles played by psychology can be enhanced, and the links to vision and TC can be better enabled. Furthermore, In South Africa, the barriers to the seamless integration of psychology into health systems are attributed to a lack of infrastructure, limited resources, and available services, human resources (clinical psychologists), effective training, and existing policies, which need to be addressed by the South African government.

Keywords: Sustainability, SDG3, Development, Health and Wellness, and Well-being.

Macroeconomics is a branch of economics that studies the overall economic system, including economic growth, unemployment, inflation and others. In the 21st century, macroeconomics continues to develop with the emergence of modern macroeconomic theory that emphasizes the role of monetary and fiscal policies in regulating the economy. In addition, technological developments and epidemics also affect macroeconomic developments in the world. This study aims to analyze economic development from the time of the Prophet and the Khulafa Al-Rasyidin (7th century) to the present. The method used in this study is a qualitative descriptive method by collecting secondary data from various related sources. Then the data is analyzed using a comparative method to find out what economic developments have occurred from the time of the Prophet and the Caliph until now. Thus, the evolution of the world's macro-economy has undergone many changes from the 7th century to the present, especially in the prevailing economic system, the factors influencing economic growth, and the ways in which people govern and manage resources.

Published: January 2025

We prove a canonical variation-type result for submersion metrics with positive intermediate Ricci curvatures. This can then be used in conjunction with surgery techniques to establish the existence of metrics with positive intermediate Ricci curvatures on a wide range of examples which had previously only been known to admit positive Ricci curvature, such as highly connected manifolds and exotic spheres. Further, we extend results of the second author on the moduli space of metrics with positive Ricci curvature to positive intermediate Ricci curvatures.
Phase-transition-induced Collapse of Proto-compact Stars and Its Implication for Supernova Explosions
Authors: Huang Xu-Run , Zha Shuai , Chu Ming-chung , O’Connor Evan P. , Chen Lie-Wen
Published: January 2025

A hadron–quark phase transition (PT) may trigger supernova explosions during stellar core collapse. However, both success and failure have occurred in previous attempts to explode dying stars via this mechanism. We systematically explore the outcomes of the PT-induced collapse of mock proto-compact stars (PCSs) with a constant entropy and lepton fraction, with spherically symmetric general relativistic hydrodynamic simulations and a controlled series of hybrid equations of state. Our results reveal the qualitative dependence of successful and failed explosions on the PT and quark matter characteristics. A small portion (∼0.04%−1%) of the released binding energy ΔE

B
transforms into the diagnostic explosion energy E
exp,diag, which saturates at  ∼6 × 1051 erg near the black hole formation. Note that our E
exp,diag represents an upper limit of the final explosion energies in realistic supernova simulations. We draw the phase diagrams indicative of the possible fates of supernova explosions driven by hadron−quark PTs, where the control parameters are the onset density, the energy gap of the PT, and the quark matter speed of sound. Our findings can guide further self-consistent investigations on PT-driven core-collapse supernovae and help identify hadron−quark PT-induced PCS collapse from future observations.
Cosmic Reionization on Computers: The Evolution of the Ionizing Background and Mean Free Path
Authors: Fan 樊 Jiawen 稼问 , Chen Huanqing , Avestruz Camille , Khadir Affan
Published: January 2025

Observations of the end stages of reionization indicate that at z ≈ 5–6, the ionizing background is not uniform and the mean free path (MFP) changes drastically. As the MFP is closely related to the distribution of Lyman-limit systems (LLSs) and damped Lyα absorbers, it is important to understand them. In this study, we utilize the Cosmic Reionization on Computers (CROC) simulations, which have both sufficient spatial resolution to resolve galaxy formation and LLSs alongside a fully coupled radiative transfer, to simulate the reionization processes. We analyze two CROC boxes with distinct reionization histories and find that the distributions of the ionizing background in both simulations display significant skewness. Further, the ionizing background in the late-reionization box still displays significant fluctuations (∼40%) at z ≈ 5. We also measure the MFP along sightlines that center on potential quasar hosting halos. The evolution of the MFP measured from these sightlines exhibits a break that coincides with the disappearance of all the neutral islands in the reionization history of each box. In the absence of LLSs, the MFP will be biased high by ≈20% at z ≈ 5. We also compare the MFPs measured in random sightlines. We find that at z ≈ 5, the MFPs measured in sightlines that start from massive halos are systematically smaller by ≈10% compared with the MFPs measured in random sightlines. We attribute this difference to the concentration of dense structures within 1 pMpc of massive halos. Our findings highlight the importance of high-fidelity models in the interpretation of observational measurements.
Collision-induced Absorption Spectra of N2 and CH4
Authors: Johnson Ryan M. , Bernath Peter F. , Billinghurst Brant , Zhao Jianbao
Published: January 2025

Collision-induced spectra are essential for radiative transfer modeling of Titan's atmosphere. We present experimental spectra of nitrogen–methane mixtures with an accompanying fit of N2-CH4 collision-induced absorption in the 30–400 cm−1 region at about 130 K. We found a peak absorption of 2.30 × 10−5 cm−1 amagat−2 at 75 cm−1 and a secondary peak of 1.35 × 10−5 cm−1 amagat−2 at 206.5 cm−1, which agrees with previous studies. Our work does not support the suggestion that N2-CH4 CIA in the far-infrared should be increased by about 50%, as suggested by spectroscopic modeling of Titan using data from A. Borysow & C. Tang.
Formation of Super-Earths and Mini-Neptunes from Rings of Planetesimals
Authors: Shibata Sho , Izidoro Andre
Published: January 2025

The solar system's planetary architecture has been proposed to be consistent with the terrestrial and giant planets forming from material rings at ∼1 au and ∼5 au, respectively. Here, we show that super-Earths and mini-Neptunes may share a similar formation pathway. In our simulations conducted with a disk α-viscosity of 4 × 10−3, super-Earths accrete from rings of rocky material in the inner disk, growing predominantly via planetesimal accretion. Mini-Neptunes primarily originate from rings located beyond the water snowline, forming via pebble accretion. Our simulations broadly match the period-ratio distribution, the intrasystem size uniformity, and the planet multiplicity distribution of exoplanets. The radius valley constrains the typical total mass available for rocky planet formation to be less than 3–6 M
⊕. Our results predict that planets at ∼1 au in systems with close-in super-Earths and mini-Neptunes are predominantly water-rich. Though relatively uncommon, at ∼1% level, such systems might also host rocky Earth-sized planets in the habitable zone that underwent late giant impacts, akin to the Moon-forming event.

Les repas diplomatiques font partie intégrante des rencontres officielles à Byzance, mais leur rôle exact mérite d'être questionné. Souvent associés à un faste incroyable, ils sont aussi le reflet des contextes géopolitiques. La question du placement des convives lors des banquets impériaux indique avec clarté la vision politique du monde qu’ont les autorités impériales. De plus, s’ils visent à établir ou prolonger la paix, ils s’avèrent des moments privilégiés pour mettre en exergue des tensions et se faire l’écho de conflits militaires.

Sustainability disclosure in the Gulf Cooperation Council (GCC) countries: Opportunities and Challenges
Authors: ElAlfy Amr , Elgharbawy Adel , Driver Tia Rebecca , Ibrahim Abdul-Jalil
Published: January 2025

This study examined the Environmental, Social, and Governance (ESG) performance of 117 companies across Saudi Arabia, the United Arab Emirates (UAE), and Qatar from 2021 to 2022 (totaling 234 observations) from the institutional theory perspective using a mixed methods approach. The research is structured in two stages: First, we analyzed ESG scores from ESG Refinitiv data to measure ESG performance based on 186 comparable metrics across 10 categories; second, we conducted a directed content analysis of sustainability reports that utilized 27 ESG disclosure indicators from the GCC Exchanges Committee's unified guidance. Integrating quantitative ESG scores with qualitative content analysis enables a deeper understanding of how companies in these Gulf countries respond to institutional pressures within their unique socio-political contexts. Our findings revealed that while ESG performance has generally improved across the three countries, the extent and nature of these improvements vary significantly. The UAE demonstrates the most substantial progress, particularly in environmental performance, driven by robust institutional frameworks and alignment with global sustainability standards. Saudi Arabia shows moderate improvements, reflecting the influence of Vision 2030 and ongoing reforms. In contrast, Qatar lags, especially in governance and social performance, due to weaker regulatory frameworks and slower internalization of sustainability norms. We found that the effectiveness of ESG improvements are closely tied to the strength of institutional frameworks, the intensity of external pressures, and the degree of internalization of sustainability norms in each country. It underscores the role of coercive, normative, and mimetic pressures in driving corporate disclosure practices. It highlights the complexities of sustainability reporting across sectors and national contexts in the GCC region. The research contributes to understanding how institutional pressures shape corporate sustainability practices in the Gulf region, offering valuable insights for policymakers, practitioners, and scholars interested in the dynamics of ESG and sustainability in emerging markets.
Vanishing magnetic field limits of solutions to the non-isentropic Chaplygin gas magnetogasdynamics equations
Authors: Zhao Jingye , Wei Zonghua , Liu Jiahui , Fan Yongqiang
Published: January 2025

This paper studied the Riemann problem for the non-isentropic Chaplygin gas magnetogasdynamics equations and investigated the general asymptotic behavior of its Riemann solutions. Due to the influence of the source term in the equations, the Riemann solutions for the non-isentropic Chaplygin gas magnetogasdynamics equations are no longer self-similar. We performed the analysis after eliminating the source term by using a velocity transformation. When the Riemann initial data of density and velocity satisfied the condition $ v_–\frac{1}{\rho_-}\geq v_++\frac{1}{\rho_+} $, as the reciprocal of magnetic flux density $ \mu $ tended to zero, the Riemann solutions of the non-isentropic Chaplygin gas magnetogasdynamics equations converged to the delta shock solutions of the non-isentropic Chaplygin Euler equations. Otherwise, the Riemann solutions converged to a contact discontinuity of the non-isentropic Chaplygin Euler equations.
The shifted wavelet $ (q, q') $-entropy and the classification of stationary fractal signals
Authors: Pacheco Julio César Ramírez , Trejo-Sánchez Joel Antonio , Rizo-Domínguez Luis
Published: January 2025

In this article, a wavelet entropy, which behaves as a shifted version of the standard wavelet $ (q, q') $-entropy of fractal signals, is presented. The shifted wavelet $ (q, q') $-entropy is obtained by computing the standard $ (q, q') $-entropy functional on a weighted relative-wavelet-energy (RWE) representation of fractal signals; it is shown that the weight within the RWE plays the role of a shifting factor in the characteristics of the standard wavelet $ (q, q') $-entropy. Therefore the shifted wavelet $ (q, q') $-entropy relocates the wavelet entropy values to any point of the fractality index range, which allows us to analyze a wide variety of fractal signal families thus improving on previously proposed entropies in the literature. Information planes for these entropies are obtained using different shifts and values of parameters $ q $ and $ q' $, which allow us to highlight the potential applications for a fractal signal analysis. Moreover, an experimental study using synthesized exact fractal signals shows that the shifted wavelet entropy can classify stationary long-memory signals from short-memory ones and can also be used to differentiate other fractal signal families.
Econometrics of insurance with multidimensional types
Authors: Aryal Gaurab , Perrigne Isabelle , Vuong Quang , Xu Haiqing
Published: January 2025

In this paper, we address the identification and estimation of insurance models where insurees have private information about their risk and risk aversion. The model includes random damages and allows for several claims, while insurees choose from a finite number of coverages. We show that the joint distribution of risk and risk aversion is nonparametrically identified despite bunching due to multidimensional types and a finite number of coverages. Our identification strategy exploits the observed number of claims as well as an exclusion restriction, and a full support assumption. Furthermore, our results apply to any form of competition. We propose a novel estimation procedure combining nonparametric estimators and GMM estimation that we illustrate in a Monte Carlo study.
Programming FPGAs for economics: An introduction to electrical engineering economics
Authors: Cheela Bhagath , DeHon André , Fernández-Villaverde Jesús , Peri Alessandro
Published: January 2025

We show how to use field‐programmable gate arrays (FPGAs) and their associated high‐level synthesis (
HLS) compilers to solve heterogeneous agent models with incomplete markets and aggregate uncertainty (Krusell and Smith (1998)). We document that the acceleration delivered by one single FPGA is comparable to that provided by using 69 CPU cores in a conventional cluster. The time to solve 1200 versions of the model drops from 8 hours to 7 minutes, illustrating a great potential for structural estimation. We describe how to achieve multiple acceleration opportunities—pipeline, data‐level parallelism, and data precision—with minimal modification of the
C/C++ code written for a traditional sequential processor, which we then deploy on FPGAs easily available at Amazon Web Services. We quantify the speedup and cost of these accelerations. Our paper is the first step toward a new field, electrical engineering economics, focused on designing computational accelerators for economics to tackle challenging quantitative models. Replication code is available on

Izbrana dela iz Hrenovih kornih knjig 3 / Selected Works from the Hren Choirbooks 3
Authors: Gatto Simone , Grabnar Klemen
Published: January 2025

This third volume of the selected musical pieces from the Hren choirbooks presents three settings of the Ordinary by Simone Gatto (c. 1545/50–1594/95), a Venetian musician active at the Inner-Austrian archducal court in Graz: a Missa Aller mi fault, a Missa Stabunt justi and a Missa Andra la nave mia. All three Masses are of the parody or imitation type, each derived from a pre-existing polyphonic composition. Specifically, Adrian Willaert’s five-part chanson Aller m’y faut sur la verdure and Orlando di Lasso’s five-part motet Stabunt justi serve as the models for two of the Masses, while the source for the third Mass remains unidentified. These compositions reflect the changing aesthetic preferences of the period, characterized by a heightened emphasis on colour contrast and word-painting. The Missa Andra la nave mia further exemplifies the increasing esteem for polychoral music at the Graz court towards the close of the sixteenth century, illustrating the growing influence of double-choir music in Inner Austria during this time. Gatto’s craftsmanship clearly marks out these three Masses as the product of an experienced composer.
Use of industrial waste-based zeolites in the fabrication of cementitious materials

Published: January 2025

Two types of zeolites, coming from the total conversion of hazardous aluminum waste, have been considered in this study: NaP-type zeolite and LTA-type zeolite. Both zeolites are proposed to be used in cementitious mortars by substituting cement content in 5, 10 and 15%. The microstructure of both zeolites was characterized and they have certain interesting characteristics to be used as supplementary cementitious materials. The main fresh state characteristics and the mechanical performance of the fabricated mortars were also evaluated. The lower particle size of LTA-type zeolite promotes a filler effect that increases the fluidity of the mortar mixes and they also acts as nucleation sites for the cement hydrates, thus accelerating the cement hydration reactions. This acceleration of the cement hydration promotes the increase of the initial compressive strength of the mortars fabricated with this zeolite type. The higher silica content of NaP-type zeolite promotes pozzolanic reactions that significantly increase the long-term compressive strength of the fabricated mortars.
Perceiving the Event of Emotion
Authors: Rowson Rebecca
Published: January 2025

I argue that the direct perception of emotion (DP) is best conceived in terms of event perception, rather than fact perception or object perception. On neither of these two traditional models can the perception of emotion be as direct as its counterpart in ordinary perception; the proponent of DP must either drop the ‘direct’ claim or embrace a part-whole model of emotion perception and its problems. But our best account of how we perceive events directly can be applied to emotion perception without any loss in directness. Not only this but there are good reasons to think that such a conception better respects both empirical evidence and the phenomenology of emotion perception.
Les compagnies ambulantes et le théâtre jésuite à Prague entre 1700 et 1763 : l’essoufflement du baroque ?
Authors: Jacková Magdalena
Published: January 2025

À Prague, il n’existe aucun théâtre fixe et on ne connaît que les troupes itinérantes professionnelles qui s’expriment principalement en allemand. Les jésuites sont les seuls à proposer des spectacles susceptibles de toucher un large public. L’ampleur et la diversité des productions sont impressionnantes : des dizaines de pièce de Kolczawa et de Pannagl sont publiées, auxquelles il faut ajouter de très nombreuses pièces manuscrites, souvent anonymes, et des centaines de programmes. Durant la première moitié du siècle, les thématiques traitées évoluent : les libertins corrigés, saints, martyrs, intrigues de cour, intrigues familiales évoluent vers une sensibilité exacerbée où la bonté, la fraternité et l’amour l’emportent sur les vertus stoïques. Lachatsch, actif de 1740 à 1760, occupe une place particulière. Ses pièces illustrent les vertus patriotiques, religieuses et familiales tout en mettant en garde contre les pièges de la vanité et de l’ambition.
Le théâtre de collège jésuite dans l’espace public polonais au XVIIIe siècle
Authors: Pawłowska Maja
Published: January 2025

Le théâtre des collèges jésuites est le seul théâtre permanent en Pologne. Essentiellement religieux au début, le répertoire évolue vers des sujets séculiers. La spécificité polonaise tient à son régime politique. En effet, comme les instituteurs doivent préparer leurs élèves à exercer leurs droits politiques dans le cadre de la diète, une formation à l’éloquence et l’argumentation est nécessaire. À côté de cet entraînement, les jésuites écrivent des pièces sensibilisant le public aux problèmes politiques contemporains. Ils cherchent à orienter les idées politiques de leurs élèves de façon tantôt voilée, tantôt explicite comme dans les spectacles allégoriques qui mettent en scène la Pologne et ses héros. La langue des spectacles évolue vers le polonais de façon à toucher un plus large public, notamment féminin. Les familles puissantes y sont louées au cours de panégyriques. Dans le registre comique, et en réaction aux piaristes qui font jouer des auteurs français, le père Bohomolec écrit des pièces en imitant Molière, qui prennent rapidement place dans le répertoire du nouveau théâtre national.
Mediating Local Identities as a Tool of Integration. The Austrian and French Regimes Compared (Southern Netherlands, 1715-1814)
Authors: Deseure Brecht , Van Gelder Klaas
Published: January 2025

In recent decades, the rise of transnational perspectives has profoundly changed our understanding of early modern regime changes and the integration of newly acquired territories, moving from the idea of occupation to adaptation, negotiation and the quest for legitimacy. This contribution applies these insights to two moments of regime change in the Southern Netherlands: the establishment of the Austrian regime in the formerly Spanish Habsburg Netherlands after 1715, and the annexation of the Austrian Netherlands and Liège by, and their integration in, the French Republic (1794), which later evolved into the French Empire. Both regime changes have mostly been viewed from a national perspective focusing on conquest and mutual difference. In this contribution, we develop a comparison between these two regime changes, concentrating particularly on local and regional identities and how the new authorities tried to integrate them into the official discourse. Such cultural integration was often stimulated from above, but, to a considerable degree, depended on the implication of regional and local administrators. More specifically, we analyse how the Austrian regime associated itself with local devotions that were closely linked with urban pride and identities, such as the veneration of the Sacrament of Miracle in Brussels. Similar policies were put in place during the French takeover. Via historical narratives displayed in speeches and ceremonial, and via their patronage of local art schools, commissaires and prefects in the Dyle and Deux Nethes departments conspicuously targeted local and regional identities rooted in the artistic past. Highlighting these practices contributes to a more nuanced understanding of the integration of the Southern Netherlands into larger state conglomerates.
