Despite a pandemic, crowdfunding continues to be a growing source of finance for small businesses across the EU. This article discusses nature and business typology of digital platforms that raise funds from the crowd. In the effort to support the ongoing uptake of new technologies in financial services, the first harmonised regime for the intermediation of financial instruments and loans to businesses via digital crowdfunding platforms has recently entered into application and promises to change the landscape of this financial service in the years to come. The new policy framework creates a robust EU-wide license, with requirements that support integration with social media, as well as the progressive creation of pan-European one-stop-shop platforms that offer multiple funding tools. Moreover, the regime also tests new boundaries in investor protection and behavioural finance, with the introduction of a system of warnings, targeted transparency on multiple levels and a conflict-of-interest framework to ensure that the platform acts as a risk neutral gatekeeper. The jury is still out and there are a number of unknowns, as this new framework will have to face the reality of well-established legal and supervisory national obstacles in its implementation.
Integration of numerical models to simulate 2D hydrodynamic/water quality model of contaminant concentration in Shatt Al-Arab River with WRDB calibration tools
Authors: Mawat Mohammed Jabbar , Hamdan Ahmed Naseh Ahmed
Published: June 2023

The hydrodynamic model is essential for building a water quality model for rivers, lakes, estuaries, and other water systems. Most model software, such as HEC-RAS, can perform a complex hydrodynamic surface water body and limitations to represent water quality for the corresponding area. In contrast, other models, like WASP, can simulate a wide range of contaminants in a multidimensional geometry of rivers, estuaries, lakes, and reservoirs. Still, it requires flow information from separate hydrodynamic models. This article aims to develop a comprehensive water quality model of the Shatt Al Arab River south of Iraq by linking HEC-RAS with WASP. A variety of software techniques has sequentially been used. This software includes GIS for DEM modification, HEC-RAS for the hydrodynamic model, Python code with PyCharm to run the external coupler, WASP software for advective and dispersive contaminant transport, and finally, WRDB software for full calibration process and results display. The results showed successful transportation of flow information had been achieved. Moreover, the article described an effective calibration process by plotting comparison graphs and statistical summaries to make the appropriate decision. Another goal of this work is to collect the equations and associated reaction rates of source/sink kinetic for eutrophication’s state variables.
Institutional Environment, Executive Equity Incentive, and Enterprise Innovation: The Case of China
Authors: Yu Haijie , Li Hong
Published: June 2023

The increase in national-level innovation driven by corporate innovation is an inherent requirement for the current shift from high-speed growth to high-quality development in China’s economy. In this study, we empirically analysed the influence of the institutional environment on corporate innovation and its underlying mechanism based on panel data of Chinese A-share listed companies from 2008 to 2016. The empirical results demonstrated that the institutional environment is conducive to the improvement of corporate innovation, and this result is validated by further robustness tests. The analysis of the companies’ subsamples showed that the stimulation effect of the institutional environment on corporate innovation is more significant in Central and Western China than in Eastern China. The role of the institutional environment is also more evident in non-state-owned small and medium-sized enterprises. Further analysis demonstrated that investment in R&D plays a mediator role in the context where the institutional environment promotes corporate innovation, and the executive equity incentives in this process have a moderating effect.

Tackling Corruption in Foreign Investment: Insights from Investment Arbitration Cases
Authors: Chaisse Julien
Published: June 2023

Over the last ten years, international investment tribunals have imported anti-corruption principles into the bilateral investment treaties (“BIT”) regime through the use of the doctrine of “unclean hands” and the requirement of “legality of the investment.” These principles have been invoked as a “trump card” defense by responding parties. In light of the rising case laws, the Article focuses on the success of the “trump card” defense of corruption invoked by host States. The Article makes several important findings. First, it shows that tribunals use the standard of a reasonable level of certainty to establish corruption – a standard below the “beyond reasonable doubt” standard employed in domestic criminal courts. At the same time, tribunals have discouraged mere insinuations of corruption without evidence. The Article also explains that this “trump card” defense is rarely successful owing to the minimal evidence offered by States in making allegations of corruption. Further, such a defense might place the entire burden of proof in rebutting corruption allegations on the investor even though the host State may have been complicit in the act. Fundamentally, the Article demonstrates that investment tribunals have not been able to effectively engage with corruption claims, due to the lack of enforceability of both the OECD Convention and the United Nations Convention against Corruption. However, this has not stopped the increasing use of the “trump card” defense. A separate mechanism such as introducing a corruption court could be a better alternative to deal with such claims.
Noise pollution and associated health impacts at Ganeshpeth Bus Terminus in Nagpur, India
Authors: Kumari Supriya , Sharma Anjali , Ghosh Ashok Kumar
Published: June 2023

Noise pollution, a man-made disaster in the present times, is becoming more severe and pervasive than ever before due to rapid urbanization, affecting quality of life in urban areas in India. Transit areas generate excessive noise which proves disastrous to human health. However, very few studies have mapped noise levels of transit terminals in India. The objectives of this study are (i) assessment of noise levels in Ganeshpeth Bus Terminus, the major interstate bus terminus in Nagpur and generation of noise contour map in ArcGIS and (ii) a qualitative assessment of the impact of traffic-related noise on the health of the people working in the terminus with prolonged exposure to noisy environment, by conducting a health perception survey based on a questionnaire comprising indicators of health parameters. This is a first-of-its-kind study on noise mapping at an interstate bus terminus in India. The results indicate that the noise levels all over the bus terminus site are much higher than the prescribed standards and the source of noise is not only the plying of vehicles but also the misuse of the public address system. Solutions have been suggested to achieve a drastic reduction in noise levels through simple planning-oriented measures.

Published: June 2023

An optimization approach is described in the research study that deals with the issue of reconfiguration networks built with certain conditions of power loss reduction and reliability. Furthermore, the reconfigured networking system seeks optimization based on criteria affecting the limitations. This study optimises specific network faults subjecting resources with no supply during reconfiguration to avoid the effect and possess through active power losses. These goals were met using the mathematical method of the optimisation process. The mathematical formulation is generated first in the system development process. As a result, a comprehensive methodology using genetic algorithm, Grey Wolf optimization (GWO), and particle swarm optimization (PSO) was developed. Finally, intended methodologies were estimated. Based on the results, it is clear that the proposed hybrid GWO-PSO approach outperforms all other methods in terms of node voltage, reliability, line currents, and computational duration. Furthermore, when optimally sized distributed generations are placed in optimal locations, total loss is reduced by up to 63% and voltage profiles improve.
The Desire for Lawlessness
Authors: Parra Jamie Luis
Published: June 2023

Jamie Luis Parra, “The Desire for Lawlessness: Law, Freedom, and the Aesthetic in The Bondwoman’s Narrative” (pp. 1–41)

This essay begins by discussing Hannah Crafts’s engagement with the debates of the 1850s over the relationship between civic law and moral philosophy. In her novel The Bondwoman’s Narrative (2002), a work probably completed in 1858, Crafts repudiates written language for its capacity to enforce and define slavery in the form of law, which snakes morality into itself by virtue of seeming to represent the people’s will when it actually contributes to also producing that will. Crafts indicates the necessity for a belief in a higher law, something beyond the written. She positively defines that something in her stunning reworking of ekphrasis. Presenting evidence for her familiarity with English language translations of writings on aesthetics by Immanuel Kant and Gotthold Ephraim Lessing, and close reading the novel’s depictions of visual aesthetic experience, the essay argues that Crafts theorizes a freedom disentangled from the law’s implicit definition of freedom as always dialectically opposed to enslavement. The novel’s narrator-protagonist, Hannah, reconceives freedom as the lawlessness expressed by her own speculative thinking, by her imaginative, creative response to visual representations.

Social behavior is essential for health, survival, and reproduction of animals; however, the role of astrocytes in social behavior remains largely unknown. The transmembrane protein CD38, which acts both as a receptor and ADP‐ribosyl cyclase to produce cyclic ADP–ribose (cADPR) regulates social behaviors by promoting oxytocin release from hypothalamic neurons. CD38 is also abundantly expressed in astrocytes in the postnatal brain and is important for astroglial development. Here, we demonstrate that the astroglial‐expressed CD38 plays an important role in social behavior during development. Selective deletion of CD38 in postnatal astrocytes, but not in adult astrocytes, impairs social memory without any other behavioral abnormalities. Morphological analysis shows that depletion of astroglial CD38 in the postnatal brain interferes with synapse formation in the medial prefrontal cortex (mPFC) and hippocampus. Moreover, astroglial CD38 expression promotes synaptogenesis of excitatory neurons by increasing the level of extracellular SPARCL1 (also known as Hevin), a synaptogenic protein. The release of SPARCL1 from astrocytes is regulated by CD38/cADPR/calcium signaling. These data demonstrate a novel developmental role of astrocytes in neural circuit formation and regulation of social behavior in adults.

Liver X receptor (LXR) agonism has theoretical potential for treating NAFLD/NASH, but synthetic agonists induce hyperlipidemia in preclinical models. Desmosterol, which is converted by Δ24‐dehydrocholesterol reductase (DHCR24) into cholesterol, is a potent endogenous LXR agonist with anti‐inflammatory properties. We aimed to investigate the effects of DHCR24 inhibition on NAFLD/NASH development. Here, by using APOE*3‐Leiden. CETP mice, a well‐established translational model that develops diet‐induced human‐like NAFLD/NASH characteristics, we report that SH42, a published DHCR24 inhibitor, markedly increases desmosterol levels in liver and plasma, reduces hepatic lipid content and the steatosis score, and decreases plasma fatty acid and cholesteryl ester concentrations. Flow cytometry showed that SH42 decreases liver inflammation by preventing Kupffer cell activation and monocyte infiltration. LXRα deficiency completely abolishes these beneficial effects of SH42. Together, the inhibition of DHCR24 by SH42 prevents diet‐induced hepatic steatosis and inflammation in a strictly LXRα‐dependent manner without causing hyperlipidemia. Finally, we also showed that SH42 treatment decreased liver collagen content and plasma alanine transaminase levels in an established NAFLD model. In conclusion, we anticipate that pharmacological DHCR24 inhibition may represent a novel therapeutic strategy for treatment of NAFLD/NASH.

This study analyzes the factors and the level of success of the national financial inclusion strategy implemented by non-profit institution SME Center UI or SMEC (Small Medium Enterprises Centre, Universitas Indonesia) using the perceptions of the assisted MSMEs (Mikro Small Medium Enterprises). This research was conducted in 2018 using a quantitative survey with a questionnaire as a data collection method. A sample of 73 respondents came from MSMEs assisted by SMEC, which selects by purposive sampling. The questions in the questionnaire are arranged based on the services provided by SMEC to its MSMEs. Factor analysis uses to identify the factors of the national financial inclusion strategy implemented by SMEC. Then the results will be calculated using a composite index to see the level of success of the national financial inclusion strategy. NFISPI  in the moderate category, with a score of 76.37%. The success of financial inclusion strategy depend on kinship and cooperation, financial education, financial responsibility, welfare support, central regulation, benefits of access to finance, and wisdom financial leadership. There needs to be more for SMEC in realizing the goals of NFIS, which see from the gap in access to finance between male entrepreneurs (58%) and women (42%). Empirical results have proven that kinship and cooperative strategies are important factors in the success of financial inclusion for MSMEs.  Collaboration between the education sector and the ministry of cooperatives and SMEs is needed to strengthen MSME businesses through kinship and mutual assistance.
Delphi Method in Analyzing of Minimum Wage Setting in Indonesia: Formula vs. Negotiation Model
Authors: Nugroho Mohamad Anis Agung , Gultom Yohanna M.L
Published: June 2023

Many countries set their minimum wages based on two models, through negotiation or mathematical formulas. In Indonesia, the negotiation model has been used to determine the minimum wages since 2003. In 2015, the law introduced the simple formula model that was further revised in 2016 with additional variables. Using the Delphi method, this study aims to find experts’ consensus regarding whether the governance of the formula model is superior to that of the negotiation model in terms of transaction cost minimization. Using the transaction cost economics approach, the two governances were compared in their performance in facilitating the negotiation,  coordination, and dispute prevention between employ-ers and workers. This study finds that most experts reached a consensus, claiming that the mathematical formula model is more efficient than the negotiation model. In addition, most of the experts argue that data from the Central Statistic Agency (BPS) and the elimination of the role of regional heads increase the efficiency of the formula model. However, no consensus was reached regarding whether the mathematical formula can outperform the negotiation model in minimizing the risk of future disputes.
Financing Biofuel Through Green Sukuk Corporate: Stage, Potential, and Maturity
Authors: Primambudi Ganjar
Published: June 2023

Climate mitigation and adaptation policy financing have emerged as a critical topics in climate discussions. Effective financing schemes are often debated as potential mitigation measures, with the proceeds going toward adaptation activities. This research aims to investigate the viability of green sukuk corporate as a source of financing for biofuel development initiatives in Indonesia. A forecasting process, indexation, and early warning system (EWS) method are used to test the model to assess possible risks at a specific maturity level. In this study, factor variables include GDP, Inflation, the Jakarta Islamic Index (JII), sukuk corporate outstanding, and accumulated sukuk corporate issued. The main findings of this study suggest that to generate sustainable biofuel finance, three-stage models/concepts must be built; the commitment to business as usual, the greenhouse gas mitigation stage, and the debt repayment stage. In terms of potential, the trend of green corporate sukuk is toward greater participation by sovereigns and non financial corporations. In terms of maturity, corporate green sukuk requires a longer repayment period than conventional bonds, with a time tenor of 3–5 years being suitable. Finally, we show that the issuance of green corporate sukuk is supported by macroeconomic stability. The bond scheme can be repaid and carried out to provide sustainable benefits for renewable energy.

Authors: Gao Hui-Qiang , Xu Shang-Dong , Zheng Jun
Published: June 2023

Background: To analyze the clinical effect of debranching thoracic endovascular aortic repair combined with ascending aortic banding. Methods: The clinical data of patients who underwent a debranching thoracic endovascular aortic repair combined with ascending aortic banding at Anzhen Hospital (Beijing, China) between January 2019 and December 2021 were reviewed to evaluate the occurrence and outcomes of postoperative complications. Results: A total of 30 patients underwent a debranching thoracic endovascular aortic repair combined with ascending aortic banding. There were 28 male patients (93.3%) with an average age of 59.9 ± 11.8 years. Twenty-five patients underwent simultaneous surgery and five patients had staged surgery. Postoperatively, two patients developed complete paraplegia (6.7%), three patients developed incomplete paraplegia (10%), two patients developed cerebral infarction (6.7%), and one patient developed femoral artery thromboembolism (3.3%). No patient died during the perioperative period, and one patient (3.3%) died during the follow-up period. None of the patients underwent retrograde type A aortic dissection during the perioperative and postoperative follow-up periods. Conclusions: Banding the ascending aorta with a vascular graft to restrict its movement and to serve as the proximal anchoring area of the stent graft can reduce the risk of retrograde type A aortic dissection.

Published: June 2023

Ni/CeO2-ZrO2 catalysts were prepared via co-precipitation and characterized by N2 adsorption–desorption, XRD, SEM, and TPR techniques. The effects of reaction temperature, carbon-equivalent space velocity (GC1HSV), and steam-to-carbon ratio (S/C) on the performance of the catalysts for ethanol steam reforming (ESR) were investigated. It was found that the best catalytic performance was obtained over the Ni/Ce0.75Zr0.25 catalyst with GC1HSV=345 h-1 and S/C=9.2. Under these conditions, H2 selectivity reached its highest value of 98% at T=725 °C, and carbon conversion reached 100% at T=825 °C. The performances of Ni/Ce0.75Zr0.25 and Ni/Ce0.5Zr0.5 were also compared at S/C ranging from 2.5 to 9.2. The results showed a higher carbon conversion for the Ni/Ce0.75Zr0.25 catalyst than for Ni/Ce0.5Zr0.5.

Published: June 2023

In this study, nanocrystalline cellulose (NCC) was used for increasing the bonding strength of urea-formaldehyde (UF) resin adhesive, with a reduction of formaldehyde (HCHO) emissions. The surface of NCC was modified by 3-aminpropyltriethoxysilane (APTES) and 3-methacryloxypropyltrimethoxysilane (MPS) for the lack of compatibility with UF resin adhesive. The modified NCC was characterized by X-ray powder diffraction (XRD), thermogravimetric analysis (TG), and wetting property. HCHO emission and bonding strength of the UF resin adhesive with modified NCC were tested according to Chinese National Standards GB/T 17657-1999 and GB/T 9846-2004. The results of XRD, TG, and wetting property from NCC modified by APTES showed more significant improvements than that from NCC modified by MPS. The HCHO emission of UF resin adhesive with 1.5% NCC modified by APTES decreased by 53.2% and bonding strength increased by 23.6%, while the results from the NCC modified by MPS were 21.3% and 7.0%, respectively.
Lignin recovered from the near-neutral hemicellulose extraction process as a precursor for carbon fiber
Authors: Luo Jie , Genco Joseph , Cole Barbara , Fort Raymond
Published: June 2023

Lignin recovered from the near-neutral hemicellulose extraction process was investigated as a precursor suitable for production of carbon fiber. Crude lignin was precipitated from the wood extract by adding sulfuric acid to lower the pH value to 1.0. The crude lignin extract was then upgraded by using hydrolysis to cleave lignin-carbohydrate bonds and to remove carbohydrates that contaminate the lignin. The precipitated solids were separated by filtration, washed with water, and then dried. Lignin recovered using the hydrolysis method was found to be high in carbon, high in total lignin, low in inorganic contamination, and low in insoluble material, but high in volatile material. The recovered lignin could be thermally spun into lignin fibers, but the spun fibers proved to be brittle, which was thought to be due to its low-molecular mass and the glassy nature of lignin. Micrographs obtained using scanning electron microscopy (SEM) illustrated imperfections on the surface and in the interior microstructure of the carbon fiber when compared to micrographs taken of commercial carbon fiber manufactured using PAN and pitch. These imperfections were thought to be related to the high volatile material content in the samples and the slow rate of heating during the carbonization process. Baker (2011) suggests that increasing the rate of heating during carbonization can reduce the degree of brittleness and improve mechanical properties.
Challenges in Facilitating Modular Instruction in Sulu AMIDST Covid-19 Pandemic
Authors: Jawali Anang Fatma T
Published: June 2023

The COVID-19 pandemic has had an unheard-of effect on the educational system. One of the projects used as a type of distant learning that makes use of self-learning modules is modular learning. This descriptive-correlational study compared the blended instructional strategy in Sulu to online and modular methods to determine the number of implementation issues. While the t-Test for Independent Samples determined the significant differences as to the Gender, One-way Analysis of Variance (ANOVA) determined the significant differences when data were grouped according to age, civil status, length of service, and education. Frequency counts and percentages determined the respondent's profile; mean and standard deviation determined the extent of subsumed categories, such as technological, individual, domestic, institutional, and community barriers. A high positive correlation was found between the challenges affecting the delivery of the blended instructional approach and the Pearson Product Moment Correlation Coefficient (Pearson r). As a result, difficulties with delivering the mixed educational approach in Sulu became apparent. The results of this study tend to support the Baticulon, Ronie E. et al. (2020) Model of Barriers (Technological, Individual, Domestic, Institutional, and Community barriers) to blended learning in the COVID-19 period, which was based on Howlett D. et al. (2009) Integration of a case-based online module.

It still needs to be thoroughly determined how to incorporate various pasture mixes at varying amounts in goat diets. Fewer farmers are feeding goats varied concentrations of Indigofera and super Napier grass, although many have already practiced incorporating different pasture types into the goats' regular grazing routines. The study aimed to determine how various Indigofera and Super Napier combinations affected goat growth, morphometry, and carcass parameters. A completely randomized design (CRD) was used to conduct the trial, with six treatments replicated four times, with Treatments 1 and 6 acting as a control. The Tukey HSD test performed multiple means comparisons across several treatments. Goats that were fed with 100% Indigofera, 80% Super Napier + 20% Indigofera, and 100% Super Napier significantly outgrew their size, as seen by their final weights of 16.93 kg, 16.68 kg, and 16.57 kg, respectively (3.16 kg, 2.90 kg and 2.67 kg, respectively). Combinations of 60% super Napier + 40% Indigofera and 70% super Napier + 30% Indigofera have a substantial impact on the amount of feed consumed (1.71 kg), whereas 60% super Napier + 40% Indigofera has a considerable impact on the goat's feed efficiency (0.60 and 0.76, respectively). Following a 60-day experiment, 100% Indigofera also had an impact on the chest circumference (57.20 cm), loin eye area (11.66 cm2), gastrointestinal contents (2.90 kg), hot carcass weight (6.72 kg), cold carcass weight (6.45%), pluck weight (0.68 kg), the weight of total trimmable fats (0.33 kg), and the percentage weight of total trimmable fats (2.02%). Additionally, 70% super Napier + 30% Indigofera, 80% SN+20% Indigofera, 70% SN + 30% Indigofera, and 60% SN + 40% Indigofera are suggested by these data.

Published: June 2023

A recently prepared fragment of the anterior end of a snout comprising occluded upper and lower jaws of a juvenile individual of Stenorhynchosaurus munozi Páramo-Fonseca et al., 2016 (Plesiosauria, Pliosauridae) is described herein. The specimen was found in the 1990s at Sutamarchán (Boyacá, Colombia), in Barremian beds of the Arcillolitas abigarradas Member of the Paja Formation. Its description provides hitherto unknown valuable morphological information on the species: dorsal anterior extension of the vomer, five premaxillary teeth (not four as was previously suggested), and anteriorly directed orientation of the first premaxillary alveolus (procumbent). New observations made on previously studied material corroborated the existence of procumbent anterior premaxillary teeth in the species. The presence of this trait highlights the close relationship of S. munozi with other early-diverging brachauchenines from the Lower Cretaceous of Russia.
