THE EFFECT OF PROFITABILITY, ASSET GROWTH AND OPERATING LEVERAGE ON CAPITAL STRUCTURE WITH COMPANY SIZE AS A MODERATING VARIABLE
Authors: Santioso Linda , Daryatno Andreas Bambang
Published: May 2024

Capital structure plays an important role in maintaining the survival of the Company. The better the capital structure owned by the Company, the better the Company will be in financing the Company's operations, even more able to survive in the event of an economic shock. The purpose of this research is to obtain empirical evidence of the effect of Profitability, Asset Growth, and Operating Leverage on Capital Structure with Company Size as a moderating variable. This study uses purposive sampling as its sampling technique and uses primary consumer sector companies as research samples. The data used in this study comes from the Financial Statements of companies listed on the Indonesia Stock Exchange. Data processing in this study used the Smart PLS program. The results showed that the independent variables of Profitability, Asset Growth, Operating Leverage had no significant positive effect on the Company's Capital Structure.  But when the profitability variable is moderated by company size, it produces a significant influence on the capital structure, while for the Asset Growth variable moderated by company size, although it has increased, it still does not significantly affect the Company's Capital Structure. From the result above, it can be concluded that the use of profitability is the key of all independent variables in influencing the capital structure. Companies that use internal funds will be better at financing the Company's operations, increasing assets, assessing the size of the company, namely utilizing the Company's retained earnings to increase the growth and survival of the Company.

Authors: Nuringsih Kartika , Maupa Haris , Taba Muhammad Idrus
Published: May 2024

In line with the sustainable development goals (SDGs), the entrepreneurial development model improves sustainability through sustainable entrepreneurship. The targeted segment to understand sustainability issues is entrepreneurs because their activities exacerbate the risk to environmental sustainability. Thus, the target achieved is community behavior towards sustainable development so that the emphasis of this concept is in the scope of citizenship behavior to build awareness of sustainable development. Therefore, a model was developed to foster sustainable entrepreneurial citizenship behavior (SECBs) among candidate entrepreneurs in Kulon Progo region, Daerah Istimewa Yogyakarta. This research is designed as a literature study that involves journals and articles in constructing the research model in line with sustainability issues. It involves seven constructs e.g., regional government support, sustainability entrepreneurial orientation, sustainability value, sustainability attitude, recognize opportunity, sustainable entrepreneurial intention, and SECBs. Totally 56 indicators are identified as tools for measuring seven constructs which will be followed up as instruments in the next study. The result serves as a foundation for the next study and information in developing entrepreneurship education. It relates to achieving the SDGs-4 in ensuring quality education and SDGs-8 in fostering decent work and economic growth.

This study examines the role of hastags (#BubarkanPOLRI) that first appeared during the Buaya vs Cicak incident where the KPK wiretapped case against the Kabareskrim Mabes Polri which was allegedly involved in disbursing funds from Bank Century customers. Hastag (#BubarkanPolri) Reappeared during the riots at the Kanjuruhan Malang stadium as quoted from the @akmalmarhali20 account "Tear gas shooting is one of the causes of dozens of deaths at Kanjuruhan stadium, STOP COMPETITION ON HUMANITARIAN GROUNDS #Jokowi #BubarkanPOLRI" and @chewulandari__ "Please have a tragedy in Malang to be resolved. Don't ask who's wrong anymore, but ask WHO IS LYING! 1 The police if they turn back the data attacking the community is easy, while the 1000 people shout the dakta is useless. Let alone #BubarkanPOLRI #UsutTuntasTragediKanjuruhan". As well as #polripresisi as a reaction that arises from the development of cases that tarnish the good name of the National Police. As quoted from the @PolsekSebbar account "West Sebatik Police personnel appeal to residents to continue to maintain kamtibmas if there is a problem immediately reported to the Police" and @PolsekLbkPakam "Lubuk Pakam Police SPKT service to the community who make Reports of Loss of Important Letters. Served humanistically, comfortably, and free of levies". This study aims to continue the previous research by comparing two different hastags, namely, #BubarkanPOLRI and #polripresisi to see if the difference in hashtags can have an impact on mobilization between the two fences. #Polripresisi able to create mobilization as measured by the number of network structures formed compared to #BubarkanPOLRI that tend to show the emotions of Twitter users about their dissatisfaction with the Polri as a State institution that should be able to protect and protect the community, of course, the goal is for the National Police to immediately fix themselves with all the dark records that already have, the analysis of this study shows how actors use hastags to get  support among twitter users for United in upholding justice.

Route Competition In Hong Kong's Aviation Industry
Authors: Qiu Yizhang , Lai Sinchit
Published: May 2024

Open sky policies have been implemented for decades, giving birth to many airline newcomers from diverse backgrounds lifting off into liberalized skies. EasyJet, Ryanair, Wizz Air, and Southwest Airlines are examples of independent budget airlines, branding the outcome of aviation liberalization and contributing to interoute competition through their networks. However, Hong Kong International Airport, which aspires to be a better and greater air hub, is crowded with local carriers, and the airport flight timetables rarely show the presence of non-local budget airlines or competing routes. This Article examines the importance of interoute competition and the role that budget airlines play in it. Upon citing the data and traffic schedule to and from HKIA, this Article looks to the HK-Japan and HK-Australia routes as examples of the lack of interoute competition in HK’s internal aviation market. Finally, this Article discusses the reasons leading to such a problem and recommends ways for policymakers to address it.
Orphans of the Orissa Famine: Capital, Charity, and Coercion in the Missionary System
Authors: Sarah Mende
Published: May 2024

Some of the most profound effects Britain imposed on society in Orissa, India came as a result of the missions that formed the majority of the protective infrastructure during the Orissa famine. Shortly after the British began their occupation of Orissa, a network of Protestant Christian missions based in England began to move into the region. Leadership came from the Christian Missionary Society, an Evangelical Anglican group, as well as Baptist figures such as Rev. J. Buckley. Their move was difficult, and for many years unsuccessful. However, the British East India Company and the Raj that followed it would pave the way for an increase in mission power through their laissez-faire policies of ignoring preexisting infrastructure and discontinuing preexisting social support systems. The missions, through their network of periodical publications, were then able to position themselves as a charitable counterpoint to the mainstream ideology of free markets at the time. In 1865, when a harvest failed as a result of British lack of infrastructure maintenance, the Protestant mission network’s opportunity arrived. The famine left many children without caretakers, and the missions, having begun a precedent of taking in orphans, became one of the only options for these children. The missions completed their takeover after the British first refused to acknowledge the famine, and then offered an ineffective response. The mission takeover quickly became so complete that secular authorities turned those seeking to give charity to the missions, since missions were some of the only organizations with a history of working directly with people in the region. The lives and identities of these famine orphans formed a microcosm of the changes to Orissa over the course of the Orissa famine.
Reversing Grutter
Authors: Bloom, Jr. Lackland H.
Published: May 2024

In 2023, the Supreme Court modified its 2003 decision in Grutter v. Bollinger. That decision had allowed colleges, graduate schools, and professional schools to explicitly consider race in the admissions process. In two cases decided together, Students for Fair Admissions v. Harvard University and University of North Carolina, a 6–3 majority of the Court held that colleges could not employ a general racial preference but could take account of how race affected the specific applicant. The decision was based on the Court’s understanding of the Equal Protection Clause of the Fourteenth Amendment and Title VI of the Civil Rights Act of 1964. Chief Justice Roberts wrote the opinion for the Court in which he held that the justifications put forth by the colleges were too vague to be evaluated by the judiciary, that racial preferences inflicted real harm, and that Grutter itself had recognized that the employment of racial preferences in college admissions were a temporary measure. In the process, Chief Justice Roberts reaffirmed that the color-blind principle was the proper focus of the Equal Protection Clause with respect to race, rejecting the competing anti-subordination theory, made it clear that universities were forbidden from providing a remedy for societal discrimination, and reaffirmed that establishing racial proportionality was an illegitimate goal. In this respect, Chief Justice Roberts brought the law in line with Bakke, J.A. Croson, and Adarand. The majority rejected Justice O’Connor’s conclusion in Grutter that university admissions were in a different context entailing less severe analysis under Equal Protection. Justice Thomas, the only justice who participated in both Grutter and the Fair Admissions cases, wrote a very lengthy concurrence expanding on the Chief Justice’s opinion and making a few points of his own.

THE RELIEF PLATE WITH FIGURES OF NIKE FROM PLATON USTINOV’S COLLECTION AND THE LEAD SARCOPHAGI FROM JERUSALEM OF THE 3rd-5th CENTURIES
Authors: Беляев Л.А.
Published: May 2024

В статье публикуется, по фотографии конца XIX в., предмет из коллекции Платона Устинова (рис. 1). Коллекция включала значительное количество предметов из некрополя Абу-Кабир в Яффо и была составлена в 1878-1913 гг. и в большей части куплена музеем университета в Осло. Устраняется неверная атрибуция вещи, которая в подписи на фотографии характеризовалась как каменный рельеф. Доказывается, что это пластина из свинцового гроба с рельефным декором. Такие гробы были известны в Средиземноморье, в III-IV вв. н. э. их производили в Финикии в прибрежных городах. В глубинной Палестине известна одна мастерская, работавшая в IV-VI вв. в Иерусалиме, которая выпустила многие сотни изделий. Их украшали античные сюжеты, к ним добавились иудейские и христианские символы. Для мастерской были характерны магические элементы - имитации обвязок и дериваты венков в виде свернутых в кольцо шнуров.

The paper publishes an item from Platon Ustinov’s collection using a photograph made at the end of the 19th century (Fig. 1). The collection assembled in 18781913 included a large number of items from the Abu-Kabir necropolis in Jaffa; a greater part of the collection was bought by the Museum of Cultural History in Oslo University. The paper corrects the wrong attribution of the item described in the inscription on the photograph as a stone relief. The paper proves that it is a plate from a lead coffin featuring a relief decoration. Such coffins were known in the Mediterranean, in the 3rd-4th centuries they were made in coastal cities in Phoenicia. There is one workshop located in Palestine heartland, which operated in Jerusalem producing hundreds of items in the 4th-6th centuries. These items were decorated with Ancient Greek narrative scenes, with some Ju-deic and Christian elements added. Magic elements imitating bands and wreath derivates in the form of coiled rods were typical of this shop.
Additional Power Losses Under Non-Sinusoidal Conditions in a 22 kV Overhead Power Line
Authors: Kovernikova L.I. , Bui Ngoc Hung
Published: May 2024

Non-sinusoidal conditions in the electrical networks cause active power losses at the fundamental frequency, corresponding to the first harmonic, and at harmonic frequencies, which are a multiple of the fundamental frequency. Non-sinusoidal currents flow through network components and create additional active power losses. One of the non-sinusoidal current sources is electronic equipment used in industrial plants to control process equipment. In Vietnam, coal mines use frequency-controlled induction motors when processing coal.  The induction motors consume non-sinusoidal current, which creates additional active power losses in the supply network. The harmonic active power does not perform useful work. It causes economic damage to both the supply network and industrial enterprises. The power supply systems in industrial areas of Vietnam, where coal is mined, are characterized by low power quality. Companies engaged in coal mining and processing are forced to pay for additional losses of active power due to the low power quality under non-sinusoidal conditions, which reduces the economic efficiency of the companies' operations. The paper presents a review of the literature on the assessment of additional active power losses in overhead power lines at harmonic frequencies. An example of calculating additional losses of harmonic active power is given for a 22 kV overhead power line, through which electrical energy is supplied to the coal grading plant of the Kua Ong-Vinacomin company. Additional losses are calculated using the measurements of harmonic voltage and current at the point of the supply network connection to the 22 kV overhead power line, through which electrical energy is supplied to the coal mine and the coal grading plant. To assess the influence of the electrical equipment of the coal grading plant on the power quality in the supply network, measurements were carried out on 0.4 kV buses of electrical substation of the coal mine.

Genesis and Structure of the Alternative Field. Conspiracy Theories, Alternative Medicine, and the Fight against the Mainstream
Authors: Bawidamann Loïc
Published: May 2024

Conspiracy theories and their relation to religion are widely discussed. Drawing on Bourdieu’s concept of social fields, this article proposes the concept of an alternative field where various actors with alternative views converge. By examining a conspiracy theory blog with links to alternative medicine and alternative religious views, the paper reconstructs how knowledge is legitimated and produced within this alternative field. The concept provides a distinct analytical approach to shed light on the intersection of religion and conspiracy theories by focusing on actors and their knowledge production, thus complementing existing research approaches.

Published: May 2024

Herein, we disclose an efficient 3-component metal-free carbosulfonylation of alkynes with readily available alkyl carboxylic acids and arylsulfinates under visible light irradiation. This photochemical approach offers a broad substrate scope of highly functionalized alkyl sulfones under mild reaction conditions and without additives. Moreover, in this protocol we employ feedstock chemicals as starting materials and moderate diastereoselectivity is displayed. The utility of our methodology is highlighted by its application in the synthesis of sedum alkaloids. Mechanistic investigations into this transformation are described.
Probing High-Order Transient Oligomers using Ion Mobility Mass Spectrometry coupled to Infrared Action Spectroscopy
Authors: Bakels Sjors , Daly Steven , Doğan Berk , Baerenfaenger Melissa , Commandeur Jan , Rijs Anouk
Published: May 2024

Understanding and controlling peptide aggregation is critical due to its neurotoxic implications. However, structural information on the key intermediates, the oligomers, is obscured by a cascade of coinciding events occurring at various time and energy scales, which results in complex and heterogeneous mixtures of oligomers. To address this challenge, we have developed the Photo-Synapt, a novel, multidimensional spectrometer that integrates ion mobility mass spec-trometry with infrared (IR) action spectroscopy within a single experiment. By combining three different, orthogonal analytical dimensions, we can select and isolate individual oligomers by mass, charge, size and shape and provide a unique molecular fingerprint for each oligomer. The broad application of this technology is demonstrated by its ap-plication to oligosaccharide analysis from glycoproteins, which are challenging to analyze due to the minute differ-ences between isomers. By integrating infrared action spectroscopy with ion mobility mass spectrometry, this approach adds an analytical dimension that effectively addresses this limitation, offering a unique molecular finger-print for each isomer.
A Bio-inspired Dendritic MoOx Electrocatalyst for Efficient Electrochemical Nitrate Reduction to Ammonia
Authors: Xu Yuan-Zi , Abbott Daniel , Dürr Robin , Ngoc Huan Tran , Mougel Victor
Published: May 2024

Drawing inspiration from the nitrate reductase enzymes, which catalyze nitrate to nitrite in nature, here we introduce a bio-inspired, reduced molybdenum oxide (MoOx) shell that is grown on top of a dendritic nickel foam core (NiNF). The resulting MoOx/NiNF material is prepared via a facile, two-step electrodeposition strategy using commercially available, low-cost precursors. This catalytic material displays a remarkable faradaic efficiency (FE) of 99% at −0.5 V vs. RHE and a high ammonia (NH3) yield rate of up to 4.29 mmol h−1 cm−2 at −1.0 V vs. RHE in neutral media. Most importantly, MoOx/NiNF exhibits exceptional stability for the nitrate reduction reaction (NO3RR), maintaining operation for over 3,100 hours at a high current density of −650 mA cm−2, with a yield rate of 2.6 mmol h−1 cm−2 and a stable average NH3 FE of ~83%. We show, through combined XPS and in-situ Raman spectroscopy, that the pronounced affinity of MoOx/NiNF for nitrate is associated with a substantial presence of oxygen vacancies within the material.
Extensive screening and performance testing of nucleating agents for the sodium acetate trihydrate phase-change material
Authors: Li Jinjie , Parkes Michael , Salzmann Christoph
Published: May 2024

Heat batteries often rely on phase-change materials that undergo phase transitions upon heat charging and release. Sodium acetate trihydrate (SAT) is considered one of the best phase-change materials in terms of storage capacity. Yet, it is well-known for supercooling which makes the search for effective nucleating agents a high priority. To perform extensive screening for nucleating agents and to test their performance, we designed a new instrument. The HeatMaster is capable of analyzing six samples on the gram-scale in parallel using the principle of power compensation which means that heat releases and uptakes can be obtained in a quantitative fashion. Out of the 36 tested nucleating agents, CaCl2·2H2O was identified as the best nucleating agent that outperforms several of the previously known nucleating agents in terms of temperature range of operation up to 80 °C. CaCl2·2H2O performs reliably as a nucleating agent for SAT down to 0.5 weight percent. MgCl2·6H2O was also identified as a nucleating agent. Yet, similar to the well-known Na2HPO4∙12H2O, its performance is not reliable after heating to 80 °C. Out of the three nucleating agents, CaCl2·2H2O shows the best performance with respect to deterioration of the heat releases upon extensive thermal cycling with a maximum temperature of 65 °C.

Published: May 2024

DNA methylation, an important epigenetic modification, is catalyzed by DNA methyltransferases and is essential in the regulation of gene expression. Here, the utility of an N-mustard analog designed to mimic the native methyl donor, S-adenosyl-L-methionine (SAM), was explored with the DNA methyltransferase 3A catalytic domain (DNMT3AC). In lieu of the expected analog transfer to DNA, methyltransferase activity was instead inhibited in a concentration dependent manner. Further investigation into the mechanism of analog inhibition did not reveal a typical competitive mechanism. Instead, mass spectrometry analysis provided direct evidence of two cysteine residues in the SAM binding site covalently modified by the SAM analog and confirmed its’ function as an irreversible inhibitor of DNMT3A.
Quantum nature of reactivity modification in vibrational polariton chemistry
Authors: Ke Yaling , Richardson Jeremy
Published: May 2024

In this work, we present a mixed quantum–classical open quantum system dynamics method for studying rate modifications of ground-state chemical reactions in an optical cavity under vibrational strong coupling conditions. In this approach, the cavity radiation mode is treated classically with a mean-field nuclear force averaging over the remaining degrees of freedom, both within the system and the environment, which are handled quantum mechanically within the hierarchical equations of motion framework. Using this approach, we conduct a comparative analysis by juxtaposing the mixed quantum–classical results with fully quantum mechanical simulations. Through this comparison, we confirm the crucial role of the quantum nature of the cavity radiation mode in reproducing the resonant peak observed in the cavity frequency-dependent rate profile. In other words, it is crucial to explicitly consider the quantized photonic states in studying reactivity modification in vibrational polariton chemistry, as these phenomena stem from cavity-induced reaction pathways involving resonant energy exchanges between photons and molecular vibrational transitions.
Seeing double: the persistent dimer-of-dimers structure of drug resistant influenza A M2

Published: May 2024

The currently circulating S31N variant of the M2 proton channel of influenza A is resistant to antiviral drugs. Recently, there has been a growing concern regarding the impact of the lipid environment on the structural features of the S31N variant. The native symmetry of the M2 tetramer remains controversial. Here we show that S31N M2 persists in a dimer-of-dimers structurein different lipid preparations independent of the amount of solvating lipids up to at least 180 lipids per tetramer. Two isoleucine residues with upfield shifted alpha carbon resonances, which are typically associated with extended conformations, are shown to be compatible with a particular side-chain rotameric state and helical backbone geometry. These chemical shifts are therefore compatible with the expected native transmembrane helical fold. Symmetry breaking at the pH sensing H37 residues, detected via peak doubling, is a stable feature of S31N M2 based on the reference strain Udorn/1972(H3N2). By contrast, the spectrum is dramatically altered for Columbia/2014/(H3N2) M2, which differs in sequence in the amphipathic helices. This highlights the allosteric coupling between the amphipathic helices and the pH sensing residues, which was detected before via the influence of aminoadamantyl inhibitors.
VIP - Variational Inversion Package with example implementations of Bayesian tomographic imaging
Authors: Zhang Xin , Curtis Andrew
Published: May 2024

Bayesian inference has become an important methodology to solve inverse problems and to quantify uncertainties in their solutions. Variational inference is a method that provides probabilistic, Bayesian solutions efficiently by using optimisation. In this study we present a Python Variational Inversion Package (VIP), to solve inverse problems using variational inference methods. The package includes automatic differential variational inference (ADVI), Stein variational gradient descent (SVGD) and stochastic SVGD (sSVGD), and provides implementations of 2D travel time tomography and 2D full waveform inversion including test examples and solutions. Users can solve their own problems by supplying an appropriate forward function and a gradient calculation code. In addition, the package provides a scalable implementation which can be deployed easily on a desktop machine or using modern high performance computational facilities. The examples demonstrate that VIP is an efficient, scalable, extensible and user-friendly package, and can be used to solve a wide range of low or high dimensional inverse problems in practice.

Published: May 2024

En el presente trabajo se reflexiona el paisaje desde la geografía cultural, la cual reconoce que la complejidad natural y cultural del paisaje son riquezas invaluables. Estas riquezas invaluables, nombradas como patrimonio en la gestión cultural, se llaman aquí herencias territoriales (HT) con la intención de tener una mirada más democrática en su identificación. Se reflexiona sobre la importancia y complejidad de identificar y categorizar estas HT de manera que puedan integrarse en una cartografía del paisaje. Se sugiere una mirada integral e interdisciplinaria para entender la dinámica del paisaje con el objetivo de generar propuestas sustentables en beneficio del lugar y la población. Para llevar a cabo lo anterior, se crea una metodología desde el enfoque de la Landscape Character Assessment (LCA) para el paisaje de Atotonilco el Alto, Jalisco (México). Los resultados son interpretaciones de los investigadores que aportan información desde lo local.

En la búsqueda de estrategias para el manejo adecuado de áreas naturales protegidas, esta investigación se encamina a establecer parámetros socioespaciales en la interfase urbano-rural y su transformación del medio natural al antrópico. Se analiza específicamente la Zona Metropolitana de Xalapa, Veracruz, pues en esta área existe una estrecha relación entre los asentamientos humanos y un área natural protegida que enmarca la mancha urbana. El objetivo es definir estrategias de transformación espacial a través de la participación, la gestión y la gobernanza, para fomentar un desarrollo integral sostenido, mediante el uso de metodologías mixtas en temas de hábitat, habitabilidad y desarrollo en el estudio del Corredor Biológico Multifuncional de la Región Capital del Estado de Veracruz (CBMRCEV). Como conclusiones se presentan evidencias de la construcción social de la identidad a través de un proceso paulatino, donde destaca el desarrollo integral y se fortalece el autoconsumo, la autogestión y el autodesarrollo.
Transportes, malha viária e enfiteuse. Estruturação urbana e fundiária em Natal, Brasil (1892-1923)
Authors: Medeiros Gabriel Leopoldino Paulo
Published: May 2024

Nas décadas de 1910 e 1920, a legislação foreira de Natal, capital do Rio Grande do Norte-Brasil, sofreu diversos ajustes e remodelações. A enfiteuse dos terrenos corroborou o processo de estruturação urbana durante o período. O objetivo principal do presente estudo é compreender o papel desempenhado pelas redes viárias e de transporte na constituição de padrões socioespaciais nesta emergente estrutura fundiária de Natal. O recorte temporal se concentra no período da República Velha (1889-1930). As fontes de dados utilizadas foram os Decretos e Mensagens de Governo Municipal e Estadual, o Censo Brasileiro de 1920, o Almanak Laemmert, (Biblioteca Nacional), o mapa de Natal de 1924 e, sobretudo, as cartas de aforamento do município digitalizadas pela Secretaria Municipal de Meio Ambiente e Urbanismo (SEMURB) do período de 1904 a 1923.
Patrimonializar mediante Ley. Historia o memoria de la lepra en el lazareto de Agua de Dios, Colombia
Authors: Nieto Carlos Eduardo
Published: May 2024

El texto analiza el proceso -hasta el momento fallido- de patrimonialización desarrollado en el antiguo lazareto de Agua de Dios en Colombia, el cual se ha centrado en la expedición de la Ley 1435 de 2011 que declara un conjunto de inmuebles como Bien de Interés Cultural del ámbito Nacional. A través del estudio de caso se abordan las tensiones entre la memoria y la historia en un contexto de patrimonialización, así como las debilidades de la política de manejo del patrimonio cultural en Colombia, que se queda corta ante las complejas condiciones históricas del sitio. Para esto, se desarrolló una investigación de enfoque cualitativo que incluyó una revisión documental preliminar, a lo que se sumó un ejercicio de observación participante con presencia sostenida en el territorio de cinco años.
