Dynamic Capital Structure and Its Speed of Adjustment: a Case of Listed Manufacturing Firms in Indonesia
Authors: Anisti Novia Putri , Chalid Dony Abdul
Published: January 2024

This study examines the determining factors and the speed of adjustment of manufacturing firms’ capital structure in Indonesia. This research uses data of 118 listed manufacturing companies from 2014 to 2018 and offers a continuation of Indonesia’s existing literature by applying a dynamic model.  The results reveal that Indonesian manufacturing firms practice optimal capital structure and are altered by firm-specific and time-varying factors. Firms’ decisions regarding capital structure are determined by firm-specific factors: non-debt tax shields, tangibility, and stock price performance. The results also indicate the speed of adjustment does exist, although the speed of adjustment finds lower than in previous research. The slowdown of the manufacturing industry growth from 2014 to 2018 turns out to be in line with the slow pace of leverage adjustment.

Leverage Deviation and Speed of Adjustment toward Target Leverage: Evidence from Indonesia Stock Exchange
Authors: Cahyaningdyah Dwi
Published: January 2024

The study tested the heterogeneity and asymmetry of adjustment speed between groups of analyzes formed based on the interaction between the direction and distance of deviation from target leverage using two-step partial adjustment model. The results show speed adjustment differences among the analysis groups and the asymmetry of the speed of adjustment where the group deviated far above the target has the highest speed of adjustment and the group deviated near below the target of leverage has the lowest adjustment speed. The group of companies deviated far above the target bear the greatest deviation costs while companies in the group diverged near below the target bear the smallest deviation costs. This result is consistent with expectations that companies bearing the highest deviation costs have the greatest pressure to immediately return to the target leverage so that the speed of adjustment will be high, while companies bearing lower deviation costs do not have greater pressure to immediately return to the target leverage so that the speed adjustment towards the target will be lower.

Authors: Rita Maria Rio , Hidayat Riskin , Kristanto Ari Budi
Published: January 2024

This study aims to examine the moderating role of debt financing in the effect of competitive ad- vantage on the performance of Lasem-Rembang batik MSMEs. Capital from debt is expected to optimize the role of competitive advantage to strengthen firm performance. The researchers used primary data through a survey of 68 batik MSME entrepreneurs who have been operating for at least 5 years. The data was processed using Partial Least Squares-Structural Equation Model (PLS)-SEM with the WarpPLS 7.0 application by including the control variable of entrepreneur education level. The findings show that competitive advantage is not proven to have a positive effect on the perfor- mance of MSMEs; on the contrary, it has a significant negative effect. Then debt financing is demon- strated to moderate the effect of competitive advantage on MSME performance. This implies that debt financing can strengthen the effect of competitive advantage on MSME performance because it produces a positive and significant effect.

Published: January 2024

The Indonesian stock market is unique because of its economic relations with China and the United States, the world’s two biggest economies that are severely impacted by the COVID-19 pandemic. This study examines the short-term impact of the COVID-19 pandemic on stock price movements on the Indonesian stock exchange. Our investigation identifies patterns of market responses in terms of stock price movements in the period. We find that the outbreak has affected, in terms of market response, the manufacturing and non-manufacturing stocks similarly. The impact of the outbreak seems to be felt by almost all economic sectors in a similar way. However, based on the result, the investors’ perception of the finance sector is more favorable relative to the other sectors during the pandemic. Several stocks identified have the potential to re-bounce if market conditions return to normal.

Authors: Arsyad Muhammad Afif , Utama Cynthia Afriani
Published: January 2024

This study investigates stock market reaction in leisure industries to the first Government announce- ment of the COVID-19 outbreak in Indonesia on March 2, 2020. This study used event study meth- odology and was supported by multiple linear regression to analyze the relationship between market reaction and independent variables. The analysis was further modeled using Fama French three-fac- tor models to estimate the expected return on firms due to the first COVID-19 outbreak announce- ment. Based on our calculation of Cumulative abnormal returns, the stock of tourism industries has more negative reaction towards a confirmed first case of COVID-19 compared to other industries. We also find that Indonesian firms with greater cash reserves experienced less negative stock returns while firms with higher leverage ratios were penalized more. Additionally, this paper does not find that firms with Chief Executive Officers (CEO) who were exposed to significant health risks from COVID-19 experienced worse stock market performances.

Authors: Vidyanata Deandra
Published: January 2024

The rapid use of social media has skyrocketed over the past decade all over the world, including in Indonesia. Organizations can significantly benefit by utilizing social media as an integral part of their marketing strategy. However, there is no consensus regarding to which extent Social Media Marketing (SMM) is able to influence Purchase Intention (PI). The purpose of this study is to examine the effect of SMM on PI based on the Value-Based Adoption Model (VAM). The research population of this study is 791 thousand accounts of @halodoc Instagram followers. Halodoc becomes an interesting object to study because it is engaged in the healthcare sector, where consumers will be thoroughly evaluating the Perceived Value (PV) of the service offered. The sample consists of 130 respondents using the purposive sampling method. This study concludes that SMM has no direct influence on PI; SMM has a positive and significant effect on PV; PV has a positive and significant effect on PI and PV fully mediates the influence between SMM on PI. This study confirms that the SMM should be focusing on establishing consumers’ favorable internal response. Nevertheless, this research still has some technical limitations, where the prospective respondents were reluctant to reply direct messages from unknown senders. .

Authors: Blanco-Varela Bruno , Sánchez-Carreira María del Carmen
Published: January 2024

La precariedad laboral constituye una problemática del mercado de trabajo que puede dilatarse en el tiempo, limitando el desarrollo profesional y las oportunidades económicas y sociales de la juventud. El objetivo del artículo es examinar la calidad del empleo y la inserción laboral juvenil en Galicia, analizando cómo influyen las características personales, familiares y educativas en la calidad de sus empleos. La investigación utiliza la Encuesta de Transición Educativo-Formativa e Inserción Laboral y aplica un modelo econométrico para investigar cómo las características personales, familiares y educativas influyen en un indicador sintético de calidad del empleo. Este indicador sintetiza las relaciones contractuales, los ingresos y las características laborales del sector, y permite aproximar la exposición a la precariedad y la calidad del empleo. Los resultados muestran que tanto el sexo femenino como el menor nivel formativo tienen mayor incidencia en la exposición al riesgo de precariedad laboral. La formación materna también influye en este resultado. Se destaca la necesidad de una mayor dotación de capital humano para sortear la vulnerabilidad social y económica en Galicia y de políticas que promuevan el acompañamiento y la orientación, especialmente para personas que llevan fuera del sistema educativo un cierto tiempo o con recorridos escolares complicados.

On Logarithmic Holder Condition and Local Extrema of Power Takagi Functions
Authors: Galkin Oleg E. , Galkina Svetlana Yu. , Mulyar Olga A.
Published: January 2024

This paper studies one class of real functions, which we call Takagi power functions. Such functions have one positive real parameter; they are continuous, but nowhere differentiable, and are given on a real line using functional series. These series are similar to the series defining the continuous, nowhere differentiable Takagi function described in 1903. For each parameter value, we derive a functional equation for functions related to Takagi power functions. Then, using this equation, we obtain an accurate two-sides estimate for the functions under study. Next, we prove that for parameter values not exceeding 1, Takagi power functions satisfy the Holder logarithmic condition, and find the smallest value of the constant in this condition. As a result, we get the usual Hölder condition, which follows from the logarithmic Hölder condition. Moreover, for parameter values ranging from 0 to 1, we investigate the behavior of Takagi power functions in the neighborhood of their global maximum points. Then we show that the functions under study reach a strict local minimum on the real axis at binary-rational points, and only at them. Finally, we describe the set of points at which our functions reach a strict local maximum. The benefit of our research lies in the development of methods applicable to continuous functions that cannot be differentiated anywhere. This can significantly expand the set of functions being studied.
Estimating the Lebesgue constant for the Chebyshev distribution of nodes
Authors: Germider Oksana V. , Popov Vasily N.
Published: January 2024

In this paper an approach to estimation of the Lebesgue constant for the Lagrange interpolation process with nodes in the zeros of Chebyshev polynomials of the first kind is done. Two-sided estimation of this constant is carried out by using the logarithmic derivative of the Euler gamma function and of the Riemann zeta function. The choice of interpolation nodes is due to the fact that with a fixed number of Chebyshev nodes, the Lebesgue constant tends to its minimum value, thus reducing the error of algebraic interpolation and providing less sensitivity to rounding errors. The expressions for the upper and the lower bounds of this constant are represented as finite sums of an asymptotic alternating series. Based on the expressions obtained, these boundaries are calculated depending on the number of nodes of the interpolation process. The error of each of the boundaries’ value is estimated based on the first discarded term in the corresponding asymptotic series. The results of the calculations are presented in tables showing deviations of the Lebesgue constant from its lower and upper estimated bounds. Dependence of the values’ errors on the number of Chebyshev nodes is depicted in these tables as well. It is numerically shown that with an increase in the number of these nodes, the estimation boundaries rapidly get close to each other. The presented results can be used in the theory of interpolation to estimate the norm of the operator matching a function to its interpolation polynomial and to estimate a deviation of the constructed perturbed polynomial from the unperturbed one.
Superstructures over Cartesian products of orientation-preserving rough circle transformations
Authors: Zinina Svetlana Kh. , Nozdrinov Alexey A. , Shmukler Valeria I.
Published: January 2024

One of the constructions for obtaining flows on a manifold is building a superstructure over a cascade. In this case, the flow is non-singular, that is, it has no fixed points. C. Smale showed that superstructures over conjugate diffeomorphisms are topologically equivalent. The converse statement is not generally true, but under certain assumptions the conjugacy of diffeomorphisms is tantamount to equivalence of superstructures. Thus, J. Ikegami showed that the criterion works in the case when a diffeomorphism is given on a manifold whose fundamental group does not admit an epimorphism into the group Z
. He also constructed examples of non-conjugate diffeomorphisms of a circle whose superstructures are equivalent. In the work of I. V. Golikova and O. V. Pochinka superstructures over diffeomorphisms of circles are examined. It is also proven in this paper that the complete invariant of the equivalence of superstructures over orientation-preserving diffeomorphisms is the equality of periods for periodic points generating their diffeomorphisms. For the other side, it is known from the result of A.G. Mayer that the coincidence of rotation numbers is also necessary for conjugacy of orientation-preserving diffeomorphisms. At the same time, superstructures over orientation-changing diffeomorphisms of circles are equivalent if and only if the corresponding diffeomorphisms of circles are topologically conjugate. Work of S. Kh. Zinina and P. I. Pochinka proved that superstructures over orientation-changing Cartesian products of diffeomorphisms of circles are equivalent if and only if the corresponding diffeomorphisms of tori are topologically conjugate. In this paper a classification result is obtained for superstructures over Cartesian products of orientation-preserving diffeomorphisms of circles.
Nonholonomic mechanical systems on a plane with a variable slope
Authors: Mikishanina Evgeniya A.
Published: January 2024

This paper considers such nonholonomic mechanical systems as Chaplygin skate, inhomogeneous Chaplygin sleigh and Chaplygin sphere moving in the gravity field along an oscillating plane with a slope varying with the periodic law. By explicit integration of the equations of motion, analytical expressions for the velocities and trajectories of the contact point for Chaplygin skate and Chaplygin sleigh are obtained. Numerical parameters of the periodic law for the inclination angle change are found, such that the velocity of Chaplygin skate will be unbounded, that is, an acceleration will take place. In the case of inhomogeneous Chaplygin sleigh, on the contrary, numerical parameters of the periodic law of the inclination angle change are found, for which the sleigh velocity is bounded and there is no drift of the sleigh. For similar numerical parameters and initial conditions, when the sleigh moves along a horizontal or inclined plane with the constant slope, the velocity and trajectory of the contact point are unbounded, that is, there is a drift of the sleigh. A similar problem is solved for the Chaplygin sphere; its trajectories are constructed on the basis of numerical integration. The results are illustrated graphically. The control of the slope of the plane, depending on the angular momentum of the sphere, is proposed for discussion. Regardless of the initial conditions, such control can almost always prevent the drift of the sphere in one of the directions.
Management of burning mouth syndrome
Authors: Hüpsch-Marzec Hanna , Cieślik Paweł , Gorzkowska Agnieszka
Published: January 2024

In this review, we discuss some practical strategies that can be useful for clinicians in the interdisciplinary and individualised management of patients with burning mouth syndrome. Burning mouth syndrome (stomatodynia, glossodynia) is a chronic, idiopathic pain syndrome accompanied by a sensation of pain or burning, scalding, pinching, numbness or stinging without clinical changes in oral cavity mucosa in the absence of abnormalities in additional tests. In addition to the above symptoms, burning mouth syndrome is characterised by a sensation of oral dryness (xerostomia), distortion of the sense of taste (dysgeusia), and food hypersensitivity. Patients may further report mood swings, anxiety, insomnia, personality disorder, chronic fatigue, headache or carcinophobia. Burning mouth syndrome has a clear predisposition to perimenopausal females, and significantly affects not only the quality of life of patients but also that of their families. The aetiopathogenesis of the disease is not fully understood, and treatment predominantly focuses on symptomatic relief. Topical therapies involve benzydamine, clonazepam, capsaicin, lidocaine, lactoperoxidase, and sucralfate. Antidepressants, antiepileptics, atypical neuroleptics, and benzodiazepines have been used in systemic pharmacological management of burning mouth syndrome. Burning mouth syndrome therapy should be a combination of pharmacological and neuromodulating effects with psychological support for both patients and their families. The therapeutic strategy should be highly personalised, interdisciplinary, and holistic.
Art therapy for children with autism spectrum disorder
Authors: Lipska Julia , Leś Klaudia Karina
Published: January 2024

Aim: Presentation of the forms of art therapy most commonly used in children with autism spectrum disorder, including their short descriptions, possible ways of working, desirable benefits and impact on children and their parents, as well as an outline of other existing forms of art therapy for children. Materials and methods: In June 2023, we searched through the PubMed and Google Scholar electronic databases. Thesis: There are many forms of art therapy, the most common being music therapy, dance/movement therapy, visual therapy, cinema therapy, and theatre therapy. They have one common aim: if they are successful, they help individuals with autism spectrum disorder to communicate and express their feelings through art, as well as decrease their depression and anxiety levels, and increase relaxation. Usually, the therapy works through mirroring other people’s behaviours, focusing the individual’s emotions on art and understanding body movements and gestures of others as well as the patient’s own. Conclusion: Art therapy may improve social skills in children with autism spectrum disorder, help them externalise their feelings, and have a positive impact on their mental health by decreasing the severity of negative symptoms. It helps them communicate, understand themselves and others, and focus their emotions on their interests and hobbies.
Differential diagnosis of conversion disorders and dysarthria. Case report
Authors: Lis-Skowrońska Anna , Jauer-Niworowska Olga , Skowroński Przemysław Ireneusz
Published: January 2024

The differential diagnosis of conversion speech disorders and dysarthria is difficult, and publications on the topic are scarce. This study describes the case of a 47-year-old woman with conversion disorders mimicking post-stroke dysarthria. A speech-language pathologist analysed the record of the woman’s speech. In speech-language diagnosis, (1) tongue and lips nonverbal movements, (2) reflexes, (3) muscle strength (preliminary clinical assessment), (4) maximum phonation time, (5) diadochokinesis (tongue tests), and (6) articulation were assessed. After the examination based on the Polish version of the Frenchay Aphasia Screening Test, aphasia was excluded. Examination results showed great variability in observed symptoms involving the non-verbal and verbal motor skills, which were inconsistent with the patient’s general medical condition. The psychological diagnosis turned out to be insufficient for the patient with conversion speech disorder. Based on this case, the authors underline the need for interdisciplinary cooperation between speech-language pathologist and psychologist in the diagnosis of conversion speech disorders.

Authors: Łabuz-Roszak Beata , Morajko Aleksandra , Sierakowska Alicja , Kandziora Krzysztof
Published: January 2024

The article presents the case of a 41-year-old man who was hospitalised because of neck and occipital pain with nausea. The patient had previously suffered an injury while riding an electric scooter. Computed tomography showed subdural haematomas and cerebral venous sinuses thrombosis, while magnetic resonance imaging confirmed intracranial hypotension. Anticoagulants were introduced. After two months, the patient was readmitted to hospital due to a sudden deterioration in his condition. Computed tomography revealed subacute subdural haematoma with mass effect. The patient was treated neurosurgically. After the procedure, consciousness disorders and left-sided paresis occurred. Follow-up computed tomography showed the presence of recurrent haematoma with intracranial hypertension. Reoperation with osteomeningeal decompression was necessary. During the following days of hospitalisation, the patient’s condition gradually improved and he was transferred to the neurological rehabilitation department. One should remember about possible consequences of intracranial hypotension, such as cerebral venous sinus thrombosis or intracerebral bleeding, which, if left untreated, may be dangerous to the life and health of patients.

között összesen 147 beteg (88 férfi és 59 nő) adatait dolgoztuk fel. A
retrospektív vizsgálatban 77 traumatológiai-ortopédiai, 49 általános sebészeti
és 21 érsebészeti beteg adatainak elemzése történt. Eredmények:
A pálcás és a szivacsmintás tenyésztések alapján traumatológiai-ortopédiai
betegeknél 39%-ban, sebészeti esetekben 53,1%-ban, érsebészeti beavatkozásoknál
66,7%-ban mutatkozott eltérés. Figyelembe véve a tenyésztési eltéréseket, a
sebzárás vagy a bőrrel való implantáció lehetősége a traumatológiai-ortopédiai
betegeknél 85,6%, sebészeti esetekben 62,5%, érsebészeti beavatkozásoknál csupán
33,3% volt. A többi esetben nyitott sebkezelés történt.
Megbeszélés: A csak a bőrflórára jellemző baktériumok
okozta fertőzés esetén a seb jobban gyógyult, mint a polimikrobás flóránál. A
legrosszabb gyógyhajlamot a multirezisztens kórokozók idézték elő. A
polimikrobás és multirezisztens kórokozókat is tartalmazó sebek esetében a
nyitott sebkezelés jobbnak bizonyult. A Gram-negatív, főleg biofilmképző patogén
kórokozók hátráltatták a bőr megtapadását, vagy elősegítették annak lelökődését.
A tenyésztések pozitivitása ellenére jó sebgyógyulást és magas sebzáródási
arányt értünk el a negatív nyomású terápiával, a seb keletkezési típusától
függetlenül. Következtetés: A negatív nyomású kezelés során a
szivacsmintás tenyésztések többletinformációt hordozhatnak a pálcás
mintavételhez képest. A szivacsból kitenyésztett, döntően Gram-negatív kórokozók
módosíthatják a kezelés során az antibiotikumválasztást és a sebkezelést. Orv

Teacher learning and collaboration in a life sciences cluster in South Africa
Authors: Mxenge Ntombekhaya , Bertram Carol
Published: January 2024

There is increasing focus on collaborative teacher learning in South Africa. In the Mpumalanga province, the Department of Education uses cluster meetings as a model of teacher development. Clusters are groups of teachers from different schools who teach the same subject. In this article we focus on the learning activities that took place in 1 cluster of life sciences teachers during 2016 and 2017. Data were generated by observing 6 cluster meetings (at provincial, district and circuit level), and by interviewing 11 members of the cluster and 2 departmental officials. Wenger’s concepts of mutual engagement, shared repertoire and joint enterprise were used to analyse the data. The findings show that the professional learning activities that took place in the cluster meetings were mostly directed at improving the Grade 12 learners’ results. The subject advisors, rather than the teachers, initiated the learning activities. The routines and resources used also focused on improving learner results. We thus argue that a managerial discourse of professionalism underpins the cluster model of professional development, primarily providing strategies intended to improve the pass rate of the Grade 12 learners and to monitor school-based assessment, rather than supporting collaborative professional learning.
Exclusion of personal injury in the CISG and application of the common law
Authors:   Korea Association for International Commerce and Information, Kim Eun-Bin
Published: January 2024

The application of the Convention on the International Sale of Goods can be divided into matters excluded under the provisions of the CISG and matters explicitly stipulated in the Convention. Among them, Article 5 of the CISG stipulates that the application of the Convention is excluded and can be applied according to the governing law to be determined. According to the Articles, this study aims to examine the contents of Personal Injury excluded from the application of the Convention, focusing on Article 5, regarding matters excluded from the application of the Convention. Applying the common law when death or injury occurs due to goods in international transactions will give uniformity to CISG and secure legal stability. After examining precedents applying the common law in the case where the buyer suffered personal injury from defects goods excluded from CISG Article 5, by examining the applicability of the common law to Personal injury that frequently occur in international contracts for the sale of goods, we intend to present a unified governing law.
„Femina oeconomica”, czyli o apoteoretycznej obecności kobiet w ekonomii
Authors:   Uniwersytet Ekonomiczny w Poznaniu, Krzyżanowska Natalia
Published: January 2024

The present study deals with the problem of apparent absence of women from socioeconomic processes as well as from the related theoretical and methodological reflections within the field of economics. The article points to the fact that gender-related ideas as well as their relevance for women’s activity in the public sphere are central to undertaking issues of women participation in economy. It does so from the perspective of such trends of scholarly reflection as feminine economics as well as the more emancipation-oriented and inequality-centred feminist economics.

Da inflação crônica à hiperinflação: observações sobre o quadro atual
Authors: RESENDE ANDRÉ LARA
Published: January 2024

RESUMO Este artigo faz uma classificação dos processos de inflação. A inflação moderada é um fenômeno representado pela Curva de Phillip. Na inflação crônica, a indexação inercial e retrospectiva são fatores importantes. A hiperinflação elimina a indexação retrospectiva e é dominada pela expectativa e pelas dificuldades financeiras do fator público. Argumenta-se que, embora o déficit do fator de inflação pública nem sempre seja a causa primária da inflação crônica, em estágios posteriores nenhum déficit do governo pode ser financiado. A falta de todas as fontes de financiamento de fatores públicos é o que caracteriza a transição para a hiperinflação. A cena brasileira atual é analisada.
A inversão da teoria clássica dos salários
Authors: SANTOS ANTONIO CARLOS ALVES DOS
Published: January 2024

RESUMO Este artigo discute que as teorias salariais de Ricardo e Marx, muito semelhantes, não são apropriadas para explicar os salários no capitalismo moderno. Propomos que a teoria de Sraffa é muito mais apropriada para discuti-la no capitalismo moderno. Para ele, a taxa de lucro é vista como uma variável independente enquanto os salários são considerados uma variável residual.
Uma nota sobre a refutação lógica da macroeconomia neoclássica
Authors: SCHWARTZ GILSON
Published: January 2024

RESUMO As teorias neoclássicas são frequentemente criticadas de um ponto de vista externalista (político, sociológico, histórico, etc.). Inconsistências internas são consideradas impossíveis, pois dadas algumas premissas “a análise neoclássica é logicamente coerente”. Bernard Schmitt, um economista suíço conhecido como keynesiano tardio, escreveu sobre o assunto. Seu argumento começa com uma discussão sobre o tempo na teoria econômica e sua relação com a contabilidade nacional padrão. A conclusão é que a macroeconomia neoclássica está enraizada em alguma metáfora ilegítima entre ajustes de preços e quantidades.
Mecanismos de redução da dívida externa dos países em desenvolvimento
Authors: MEYER ARNO , MARQUES MARIA SILVIA BASTOS
Published: January 2024

RESUMO Do ponto de vista dos países em desenvolvimento, a chamada estratégia da dívida convencional é claramente insatisfatória, principalmente porque subestima a dimensão da crise e os custos internos do ajuste imposto aos países devedores. Novos empréstimos privados, de qualquer modo cada vez mais difíceis de obter, não seriam uma solução, no sentido de aumentarem uma dívida que já é extremamente elevada. Alguns mecanismos para reduzir o estoque da dívida externa foram introduzidos em recentes acordos de reescalonamento com bancos credores, como trocas de dívida por ações, recompras e troca de parte da dívida por títulos de longo prazo. No entanto, para muitos países, esses instrumentos de mercado não proporcionarão uma redução suficientemente grande do ônus das transferências financeiras para o exterior. Portanto, é necessário chegar a uma solução abrangente e duradoura para o problema da dívida externa, através da concepção de um ambiente institucional e legal adequado que possa fornecer mais suporte e garantias adicionais à implementação de esquemas de redução da dívida.
