Published: January 2024

Aiming to enhance the ns-LIBS signal, in this work, we introduced orbital angular momentum to modulate the laser phase of the Gaussian beam into the vortex beam. Under similar incident laser energy, the vortex beam promoted more uniform ablation and more ablation mass compared to the Gaussian beam, leading to elevated temperature and electron density in the laser-induced plasma. Consequently, the intensity of the ns-LIBS signal was improved. The enhancement effects based on the laser phase modulation were investigated on both metallic and non-metallic samples. The results showed that laser phase modulation resulted in a maximum 1.26-times increase in the peak intensities and a maximum 1.25-times increase in the signal-to-background ratio (SBR) of the Cu spectral lines of pure copper for a laser energy of 10 mJ. The peak intensities of Si atomic spectral lines were enhanced by 1.58-1.94 times using the vortex beam. Throughout the plasma evolution process, the plasma induced by the vortex beam exhibited prolonged duration and a longer continuous background, accompanied by a noticeable reduction in the relative standard deviation (RSD). The experimental results demonstrated that modulation the laser phase based on orbital angular momentum is a promising approach to enhancing the ns-LIBS signal.
Modeling the contribution of secondary aerosols on aerosol scattering ensemble: a comparative analysis of the scattering abilities of different aerosol species
Authors: Arreyndip Nkongho Ayuketang , Joseph Ebobenow
Published: January 2024

Atmospheric transport processes and conditions can cause primary aerosols to interact, giving rise to secondary aerosols with unique chemical and physical properties. These new species of aerosols can potentially influence the light-scattering properties of the aerosol ensemble and thus the climate system in ways that are not yet fully understood. In this study, the effects of different aerosol types on the scattering of incident solar radiation are modeled and the contribution of secondary aerosols to the aerosol scattering ensemble is highlighted. Using the discrete dipole approximation method, the scattering properties of freshwater droplets, sea salts (liquid, dry, and wet solids), ice crystals, clay minerals, clay particles coated with a thin film of water and sea salt droplets, black carbon (BC), and a complex particle of clay, sea salt, and BC with sulphate coating are calculated and compared. The calculations assume a spherical particle shape model for marine aerosols, a distorted cube for wet salts and ice, and a distorted ellipse with an induced surface roughness length for terrestrial aerosols at a size parameter of x=5 and a wavelength range of 400 to 750 nm. The results show that tiny ice crystals trapped in freshwater droplets are the most efficient atmospheric scatterers, followed by sea salt droplets, while BC absorbs the most compared to other aerosols studied. On average, the atmospheric interaction between marine and terrestrial aerosols is able to enhance atmospheric light scattering and polarisation by aerosols compared to terrestrial aerosols. This study suggests that the scenario in which there are many freshwater aerosols in the atmosphere can be very healthy for the Earth’s system compared to other aerosols. Therefore, we suggest that when formulating the radiative properties of aerosols in climate models, the scenarios of dominant freshwater aerosols and the contribution of secondary aerosols should not be ignored. The results presented here may be useful in the fields of Geoengineering and Aerosol-cloud microphysics.

Published: January 2024

Pr3+-doped ZnF2-based glasses were prepared by using a melt-quenching method in dry N2 atmosphere. Under the excitation of a 588 nm light emitting diode (LED), ultrabroadband emissions ranging from 1245 to 1640 nm were obtained from the Pr3+-doped ZnF2-based glasses, which originate from the transitions 1D2→1G4 (producing E + S-band emission) and 1G4→3H5 (producing O-band emission) of Pr3+. The shape of the emission spectra could be tailored by varying the concentration of Pr3+. Emission spectra with the maximum full width at half maximum (FWHM) of 215 nm (1289 nm-1504 nm, covering the O + E + S-band) was obtained in the ZnF2-based glass at a doping concentration of 5000 ppm. The effects of the phonon energy of the matrix on O + E + S-band emission were also investigated. Our results showed that Pr3+-doped ZnF2-based glasses with low phonon energy might be used for constructing O + E + S-band lasers and optical amplifiers.

Published: January 2024

Die Einflüsse der digitalen Transformation (DT) haben Veränderungen in vielen Aspekten der Arbeit ausgelöst, was zu veränderten Anforderungen, nicht nur an die Fähigkeiten und Leistungen von Mitarbeiter*innen führt, sondern insbesondere deren Wohlbefinden (Well-being) beeinflusst. Ein positives Wohlbefinden ist wiederum Schlüssel zu einer erfolgreichen digitalen Transformation. Dieser Artikel zeigt auf, wie sich die DT insbesondere auf die Motivation im Hinblick auf psychologische Grundbedürfnisse gemäß der Selbstbestimmungstheorie von Mitarbeiter*innen in verschiedenen Lebensphasen und somit auf das Well-being auswirkt. Hierzu wurden Fokusgruppen mit Expert*innen aus dem Handwerk befragt. Im Vergleich der in dieser Studie betrachteten Bedürfnisse (Autonomie, Verbundenheit, Kompetenz und physische Gesundheit) wird die Notwendigkeit einer digitalen Kompetenz deutlich und als wesentlicher Erfolgsfaktor für das Well-being identifiziert. Die Ergebnisse der Studie zeigen weiterhin, dass die DT sowohl positive als auch negative Auswirkungen auf psychologische Grundbedürfnisse hat, allerdings je nach Lebensphase und Arbeitsumfeld unterschiedlich wahrgenommen wird. So wurden beispielsweise im Handwerk positive Einflüsse auf das digitale Kompetenzbedürfnis von jungen Mitarbeiter*innen deutlich, die bei älteren Generationen als stresserzeugende Anforderungen wahrgenommen werden und sich langfristig negativ auf die physische Gesundheit auswirken können. Dieser Artikel bietet Impulse für die weitere Forschung im Kontext der Auswirkungen der DT sowie Implikationen für die erfolgreiche Umsetzung der DT in der Praxis.

Novel methods facilitating the mechanistic interpretation of multiscale optical remote sensing measurements
Authors: Oivukkamäki Jaakko
Published: January 2024

Plant physiology concentrates on the study of plant internal processes, such as growth, nutrient uptake and photosynthesis. The quantification of photosynthesis regulation is significant in understanding how plants react to the changing climate. Spectral remote sensing methods, using both reflected light in the visible and near infrared wavelengths, as well as chlorophyll fluorescence, are used to gather information about plant physiological variables. These methods have developed rapidly, prompted by the advances in remote sensing platforms and sensors. However, interpretation of remote sensing signals can be challenging. Due to canopy heterogeneity, the signal is affected by various elements, such as scattering, soil background and canopy structural effects. Additionally, open questions remain linked to the underlying mechanistic processes in the leaf modulating the optical signal, such as nutrient contents and leaf photochemistry, and how these processes and the optical signals diverge in response to temporal variation. Through multi-scale measurements, this thesis aims to advance the interpretation of optical remote sensing signals as they are affected by spatial and temporal variation, while promoting the use of novel methods and devices. Results indicate that diurnal and long-term variation of solar induced fluorescence (SIF) is driven by photosynthetic and structural factors, causing possible misinterpretations in SIF data. Additionally, depending on the scale of observation, results show that the capacity of remote sensing to detect changes in foliar nutrients depends on the covariation of nutrients, pigments and canopy structure, underlining the need for both leaf and canopy level measurements. Finally, we advocate for the implementation of a novel miniaturized fluorometer, demonstrating the ability to track the seasonal regulation of photosynthesis using integrated measurements of chlorophyll fluorescence and gas exchange. The results from this thesis underline the need for simultaneous multi-scale measurements of leaf and canopy physiological factors to further our understanding of photosynthesis regulation.
Dynamic box assignment planning in log yards
Authors: Gartner Maria A. , Kaltenbrunner Matthias , Gronalt Manfred
Published: January 2024

The situation on the log yard changes seasonally and also over the years. The quantities of assortments to be stored, their number and also the type of wood can change. To respond to this, we have developed a dynamic log yard planning model for assigning roundwood to specific ejection boxes and storage areas in order to minimise the overall transport distances of the loaded transportation vehicles on the log yard, including any possible re-allocation of assortments. The study centres on the log yard of a medium-sized hardwood sawmill in Europe, with actual cutting data from a six-month period. We are comparing a multi-period binary integer program with a model that operates on a period per period basis and a solution approach that splits the problem into two subproblems and solves them sequentially. The models undergo testing with decreasing space capacities at the storage boxes on the log yard and are compared. If capacity is continuously decreasing from 100% to 80%, then period per period planning is on average 13% worse than multi-period planning. We also investigate how the solutions change when twice as many or half as many assortments are stored at the log yard. In addition, we study how much the solutions improve when logs can be removed from the storage boxes to clear them and release them for other material in the following period.
Is there any relationship between nutrition, stress, physical exercise and amenorrhea?
Authors: Odarchenko A. S. , Andreeva E. N. , Grigoryan O. R. , Absatarova Yu. S.
Published: January 2024

Amenorrhea is the absence or abnormal cessation of the menstrual cycle. Functional hypothalamic amenorrhea (FHA) is one of the most common and least studied forms of secondary (hypothalamic) amenorrhea that occurs after adaptation failure in response to mental, social and metabolic irritants. At there are no common threshold values of potential irritants and markers of efficacy for female patioents with FHA. Methods of diagnostics, treatment and prevention of FHA stay still not personalized, but empirical. The most promising solution of present problem is combination of nutritive and mental correction among females with FHA. Also, the most promising step is searching and studying of omics (genomic, epigenomic, transcriptomic, proteomic and metabolomic) markers of hypothalamic–hypophysial-gonadal axis disruption. This review shows the association between amenorrhea and stress, changes in nutrition or weight, excessive physical activity, and the COVID-19 pandemic. The literature was searched in Russian and English languages in eLibrary, MEDLINE, and Scopus databases mainly for the last decade. Due to the insufficient study of the chosen topic, sources dating back to the 1990s were also selected.

Metanálise da Produção Científica Sobre os Solos dos Municípios do Triângulo Mineiro e Alto Paranaíba nos Últimos 30 Anos
Authors: Machado Henrique Amorim , Rezende Patrícia Soares , Milagres Alcione Rodrigues , Gabriel Vinícius Nunes de Lima , Fonseca Fabricio Cunha
Published: January 2024

A mesorregião geográfica do Triângulo Mineiro e Alto Paranaíba possui economia fortemente voltada ao agronegócio, com níveis de produção de grãos e cana-de-açúcar que a colocam em posição de destaque no cenário político e econômico de Minas Gerais. Todavia, a produção científica voltada à diversidade de solos desta região foi subvalorizada em detrimento de outras regiões do Estado e do País, onde os solos apresentam características geológicas e geomorfológicas mais diversas e então mais intrigantes.  O objetivo deste trabalho é avaliar a evolução e espacialização da produção bibliográfica com a temática central de solos na mesorregião do Triângulo Mineiro e Alto Paranaíba. Para isso, foram selecionados artigos das três últimas décadas, de cinco importantes revistas, que tinham como tema central o solo dentro dos munícipios pertencentes a região estudada. A partir dessa primeira triagem estes artigos foram analisados levando em conta: perfil dos autores (gênero e instituição pertencente); quantidade de autores por artigo; métodos utilizados; e distribuição destes artigos pela região selecionada. Os resultados apontam que há uma concentração de artigos em quatro municípios e um vazio em outros 40. A produção científica nos recortes analisados se mostrou fortemente dominada pelo sexo masculino. Apesar da mesorregião possuir 11 instituições públicas de ensino superior, a pesquisa sobre solos se mostrou incipiente na maioria dos municípios. Em relação aos métodos utilizados pelos pesquisadores, municípios onde mais parcerias institucionais foram viabilizadas, houve simultaneamente um aumento no número de técnicas e métodos explorados nas investigações das problemáticas. Mesmo com a área de estudo apresentando uma relativa homogeneidade geológica e geomorfológica que confere aparente monotonia   à paisagem, conhecer sua pedodiversidade, assim como a importância econômica para a agricultura, justificam a necessidade de uma retomada nos estudos de solos para o Triângulo Mineiro e Alto Paranaíba, principalmente explorando métodos e municípios ainda pouco conhecidos.
The economic and political development of African states in the historical context of the decolonization process
Authors: Diallo Boubacar Sidi
Published: January 2024

The study of decolonization has long been dominated by political history, focused on formal emancipation of nations at the turn of the 19th and 20th century, societies subject to European colonial administration. The article reveals the reasons for the emancipation of colonised nations and the construction of a new social and economic order in the world. It also presents the relationship between decolonisation and the new global economic hierarchy. In fact, decolonisation did not change anything in the economic and political relations between former metropolises and former colonies, similarly at the cultural level, where the language of the coloniser still dominates in the official sphere and in education.

Action of automorphisms on irreducible characters of finite reductive groups of type 𝖠
Authors: Shirjian Farrokh , Iranmanesh Ali , Shafiei Farideh
Published: January 2024

Let 𝐺 be a finite reductive group such that the derived subgroup of the underlying algebraic group is a product of quasi-simple groups of type 𝖠. In this paper, we give an explicit description of the action of automorphisms of 𝐺 on the set of its irreducible complex characters. This generalizes a recent result of M. Cabanes and B. Späth [Equivariant character correspondences and inductive McKay condition for type 𝖠,J. Reine Angew. Math.728(2017), 153–194] and provides a useful tool for investigating the local sides of the local-global conjectures as one usually needs to deal with Levi subgroups. As an application we obtain a generalization of the stabilizer condition in the so-called inductive McKay condition [B. Späth, Inductive McKay condition in defining characteristic,Bull. Lond. Math. Soc.44(2012), 3, 426–438; Theorem 2.12] for irreducible characters of 𝐺. Moreover, a criterion is given to explicitly determine whether an irreducible character is a constituent of a given generalized Gelfand–Graev character of 𝐺.
Polynomial maps and polynomial sequences in groups
Authors: Hu Ya-Qing
Published: January 2024

This paper presents a modified version of Leibman’s group-theoretic generalizations of the difference calculus for polynomial maps from nonempty commutative semigroups to groups, and proves that it has many desirable formal properties when the target group is locally nilpotent and also when the semigroup is the set of nonnegative integers.
We will apply it to solve Waring’s problem for general discrete Heisenberg groups in a sequel to this paper.
Rethinking context: realisation, instantiation, and individuation in systemic functional linguistics
Authors: Doran Y. J. , Martin J. R. , Herrington Michele
Published: January 2024

In spite of decades of research developing a model of language and context, there is little consensus in systemic functional linguistics (SFL) about how context should be modelled and how language and context are related. In this paper, we review recent work in SFL which focuses on modelling register as a resource – reconceiving field as a resource for construing phenomena, tenor as a resource for negotiating social relations, and mode as a resource for composing texture. This work has a number of implications for SFL’s conception of realisation (as strata of abstraction), instantiation (as a cline of generalisation), and individuation (as a scale of belonging). For realisation it bears critically on the issue of whether or not to adopt a stratified model of context (as register and genre) and the relationship between extrinsic functionality (field, tenor, and mode) and intrinsic functionality (ideational, interpersonal, and textual metafunctions). For instantiation, it bears critically on our modelling of principles for coupling (co-selecting and arranging choices within and across languages and related modalities of communication) – for example mass, presence, and association. And for individuation, it bears critically on the perspectives of allocation (i.e. how access to meanings and their uptake is distributed across communities) and affiliation (i.e. how meanings are used to collaborate and struggle, within and between social groups). Our basic aim in this paper is to suggest a model for improving traction as far as SFL work on language in context is concerned, fully embracing a multimodal perspective on language and related modalities of communication as resources for meaning.
Effects of temperature and strain rate on the deformation microstructure and hardness of Al–Zn eutectoid damping alloy
Authors: Wang Shuyi , Zhang Song , Xu Yonggang
Published: January 2024

The effects of temperature and strain rate on the deformation microstructure and hardness of Al–Zn eutectoid damping alloy was systematically investigated. The results show that the deformed alloy is mainly composed of eutectoid structure with η-Zn distributing on α-Al matrix. There are two forms of η-Zn particles in the eutectoid structure of the deformed alloy. The first type of η-Zn particles (η-ZnI) have relatively large sizes and display irregular morphology; another type of η-Zn particles (η-ZnII) have relatively small sizes and are characterized by dispersion distribution. There exist predominant η-ZnI particles at lower temperature and higher strain rate while dominant η-ZnII particles at higher temperature and lower strain rate. The hardness of the Al–Zn eutectoid damping alloy shows an overall rising trend with increase in temperature and decrease in strain rate. In particular, the highest hardness values (up to 113.07 HB) are obtained at 648 K/0.01 s−1.

Cette étude présente une approche itérative de priorisation de stratégies d’économie circulaire (ÉC) pertinentes en matière de réduction des émissions de gaz à effet de serre (GES) pour la production de grains dans Lanaudière, au Québec, à l’aide de l’analyse du cycle de vie (ACV). Après une revue de la littérature des stratégies d’ÉC généralement utilisées dans le domaine de l’agriculture, nous avons identifié les principaux contributeurs (points chauds) aux émissions de GES le long du cycle de vie de la production de grains. En partant du principe que les acteurs céréaliers devraient concentrer leurs efforts sur ces principaux contributeurs pour réduire les émissions de GES de manière efficace, nous avons identifié des stratégies d’ÉC axées sur ces contributeurs. Les impacts et les bénéfices environnementaux de la mise en place de ces stratégies ont été quantifiés à l’aide d’une analyse du cycle de vie (ACV) qui a permis de mettre en lumière les conditions nécessaires pour que l’ÉC rime bien avec réduction d’impacts. Des recommandations concrètes ont ainsi pu être établies, puis des stratégies d’ÉC sur mesure pour chaque producteur dans son contexte territorial ont été proposées.

Dans le contexte VICA (volatile, incertain, complexe et ambigu) actuel, le numérique a le potentiel de soutenir la création de valeur des PME et de contribuer à développer leur résilience dans l’atteinte des objectifs stratégiques. Il est désormais possible, à l’aide des technologies de l’industrie 4.0, de mesurer une productivité soutenue par un contrôle de gestion arrimé aux pratiques durables. Étant donné que le virage numérique n’a été effectué que par une minorité des PME au Québec et en considérant que la maturité technologique des PME régionales, particulièrement au Saguenay-Lac-Saint-Jean (SLSJ), reste à définir, la présente étude vise à innover grâce à un modèle d’analyse du niveau de la maturité numérique incorporant un indice des pratiques durables de la PME.

THE EFFECT OF ULTRASOUND PRETREATMENT ON OIL ABSORPTION AND QUALITY OF DEEP-FRIED CHICKEN SCHNITZELS
Authors: COZAİN MONTİEL Anahi Guadalupe , SOYOCAK Hilal , TURHAN Sadettin
Published: January 2024

Although deep-fried products are enjoyed by consumers of different age groups, they contain large amounts of oil, which affects product quality and cannot fail to meet the demand for a healthy diet. In this study, the effect of ultrasound pretreatment on the oil absorption and quality of deep-fried chicken schnitzels was investigated. For this purpose, chicken schnitzel samples were subjected to ultrasound pretreatment at different amplitudes (32 and 64%) and times (10, 20, and 30 min) and then deep-fried at 180 °C. Ultrasound pretreatment improved the crispness by reducing the hardness of schnitzel samples and also reduced oil absorption by 36-53%. According to the findings obtained from SEM analysis, ultrasound pretreatment caused collapses and deformations in the microstructure of the schnitzel samples, leading to the formation of many microscopic channels. Also, ultrasound pretreatment kept the original sensory properties of the schnitzel samples. These results show that ultrasound pretreatment has greatly improved the quality of chicken schnitzels.

Published: January 2024

The review explored various flumes used for open channel flow measurement and provided insight into operational concepts, discharge measurement, range of flow, head loss requirements, degree of accuracy and submergence, advantages, and limitations for use. The reviewed flumes included; Parshall flumes, Montana flumes, Cutthroat flumes, H-flumes, Trapezoidal flumes, Replogle-Bos-Clemmens (RBC) flumes, Palmer-Bowlus flumes and Central Baffle flumes (CBF). Based on the stage and discharge relationship, the reviewed flumes have a reasonable accuracy of ± 10 % over a wide range of flows. RBC flumes are the most accurate flumes (± 2 %). For flows that deal with a lot of sediments, most flumes have self-cleaning capability except for Palmer-Bowlus flumes and Central Baffle flumes. H-flumes have low resistance to submergence. The submergence transition for H-flumes is only 25-30 %. RBC flumes and Palmer-Bowlus flumes have the highest submergence (90 %). CBF and Palmer-Bowlus flumes need to be improved in order to have self-cleaning capability. Submerged flow corrections need to be developed and published for Palmer-Bowlus flumes and RBC flumes. The reviewed flumes effectively operate with a minimal head loss. The review has provided an insight on selection of an appropriate type of flume for flow measurement in open channels.
Systematic Risk in Emerging Markets: a High-Frequency Approach
Authors: Arief Usman
Published: January 2024

The study investigates how systematic, continuous, and discrete (jump) risk can explain the equity returns in Southeast Asia markets. Using the latest econometric techniques and a high-frequency dataset, I construct two high-frequency betas associated with intraday continuous and discontinuous risk premia. To improve consistency, I employ several statistical robustness levels and multiple frequencies (one minutes, five minutes, ten minutes, and thirty minutes). The findings show that both continuous and discontinuous risk premia are significant and positive in Indonesia, and these results are consistent for lower frequency data samples. Furthermore, the study reveals that diffusive and jump risk premia have different impacts in other countries, but the results are not consistent for lower frequency samples.

Digital Marketing Strategy to Increase Sales of SHIBIRU MSME Products
Authors: Luhung Binawan
Published: January 2024

Social media is used as a digital marketing strategy by many companies. This strategy is also implemented by SHIBIRU, a MSME which is engaged in the production of natural dyes. The purpose of this study is to find a digital marketing strategy as an effort to improve product marketing performance, analyze the inhibiting and driving factors in the application of digital marketing, and find solutions to the obstacles in the application of digital marketing of SHIBIRU products. The research was conducted using qualitative methods. Data was collected through in-depth interviews with 11 informants consisting of owners and buyers of SHIBIRU. The data were coded using the NVivo 12 application. The results showed that the digital marketing strategy implemented by SHIBIRU included the initiation stage with the important elements of target audience and channel choice. The main inhibiting factor stems from the unavailability of specialized personnel in the field of digital marketing. The main driving factor comes from the existence of a fairly strong communication in the community between craftsmen who use natural dyes. The solution to overcome SHIBIRU's digital marketing constraints is to use specialized personnel with adequate and relevant capabilities to handle digital marketing.

Advances in information and communication technology have made it easier for public figures, such as the late Kobe Bryant, a basketball star from the United States, to be recognized by people around the world, including Indonesia. Sportswear and footwear manufacturer Nike has capitalized on its popularity to market sports products, especially basketball shoes, products that fit Kobe Bryant’s area of expertise. This study aims to analyze the effect of attitudes towards Kobe Bryant as an endorser, attitudes towards the Nike brand, and subjective norms on consumer purchase intentions for Nike brand basketball shoes. The population in this study are Indonesian people who have knowledge of Kobe Bryant and the Nike brand but have never bought Nike brand basketball shoes. Primary data was collected by distributing questionnaires boldly to 231 respondents. Purposive sampling tech- nique aims to be used to determine the sample. Four hypotheses have been tested using the AMOS program version 24 and the Structural Equation Modeling (SEM) method, and all hypotheses are supported.

This study aims to determine the effect of destination image, visitor experience, and visitor engagement on visit intention through visitor satisfaction. The population in this study were visitors to the National Museum. The sampling technique used was purposive sampling with 148 respondents. The data analysis method uses a structural equation model with the help of smartPLS software. The results of the study show that there is a significant effect of destination image on visitor satisfaction, visitor engagement on visitor satisfaction and visitor experience on visit intention. Meanwhile, the results also show that there is no effect of destination image on visit intention, visitor satisfaction on visit intention and visitor experience on visitor satisfaction. The addition of the customer engagement and customer satisfaction variables to the model is originality in this study in measuring the desire of visitors to return with moderation of customer satisfaction. The managerial implication of this research is that the management of the national museum should increase activities that can enhance the image of the museum among the public as a tourist destination which, in addition to providing education, also provides pleasure, especially for the younger generation to prefer museums.

Published: January 2024

Despite the growing urgency, discussions about the diffusion of this technology are still challenging to identify and understand. This study attempts to investigate further the intention of blockchain adoption in society. This study used a survey strategy and was analysed using structural equation modelling. Furthermore, this study collected 96 respondents using a purposive sampling technique. The findings show that a few hypotheses diverged from the developed model. Blockchain adoption is suitable for today's problems and has a relative advantage over other technologies in influencing individual perceptions. However, the limited knowledge of society makes blockchain adoption only focused on a particular context. The role of the social environment is more visible in its significance on the intention to adopt blockchain technology along with individual perceptions. The research model attempted to extend the existing technology adoption behaviour theory widely used to understand technological adoption.
Can Instagram Attributes Affect Store Loyalty Mediated by Application Engagement and Interaction Intentions?
Authors: Palenewen Endaina Yuki Hoonekita , Ariadi Gede
Published: January 2024

The amplifying importance of Instagram and its flourishing embracing proposes a massive prospect for firms to promote their products that deliver an endeavor to identify customers’ behaviors well. The research aims to recognize application attributes of perceived ease of use (PEOU), information quality, perceived usefulness, and system quality toward store loyalty from the Technology Acceptance Model (TAM) lens. Moreover, it elaborates on the theory of Planned Behavior (TPB) to construct interaction intention and application engagement as mediator variables that apply the conceptual model among application attributes and store loyalty. This study uses a quantitative approach where questionnaires are distributed to 272 consumers who know or follow the Instagram of the Coffee Shop in Salatiga, Indonesia. The outcomes expose which interaction intention and application engagement are essential in the linkages among perceived usefulness, system quality, and information quality toward the store. Conversely, both mediator variables could not mediate the linkages between PEOU and store loyalty. Theoretically, there is a synergy amid theory TAM and TPB, revealing that perceived usefulness is most influential as antecedents affect store loyalty through interaction intention and application engagement.
Corporate Debt, Institutional Differences and Firms’ Financial Distress in Emerging Economies under Uncertainty
Authors: Mulyaningsih Tri , Sarmidi Tamat , Cahyadin Malik
Published: January 2024

Firms with high leverage are more vulnerable, particularly during uncertainty due to the COVID-19 pandemic. This study aims to examine the impact of leverage on firms’ financial distress by capturing two countries, Indonesia and Malaysia, which have different levels of leverage and financial development that affect access to external funding. The Altman Z-score—for a rich dataset comprising quarterly data of publicly traded companies between 2015 and 2020—is calculated to measure firms’ financial distress. Furthermore, the Difference-in-Differences (DiD) technique is employed to test the hypothesis that highly leveraged firms have a higher bankruptcy risk that leads to financial distress during the COVID-19 pandemic. This study finds that firms’ financial distress during the pandemic is higher than prior the pandemic. Indonesian firms’ financial distress was higher than Malaysian firms. Finally, highly leveraged firms are exposed to higher bankruptcy risk than firms with lower debt.
Numerical Study of the Rate of Convergence of Chernoff Approximations to Solutions of the Heat Equation

Published: January 2024

The article is devoted to construction of examples illustrating (using computer calculation) the convergence rate of Chernoff approximations to the solution of the Cauchy problem for the heat equation. Two Chernoff functions (of the first and second order of Chernoff tangency to the double differentiation operator) and several initial conditions of different smoothness are considered. As an illustration for the initial condition equal to the absolute value of the sine function to the power of five over two, a graph of the exact solution of the Cauchy problem and graphs of the tenth Chernoff approximations given by two different Chernoff functions are plotted. It is visually determined that the approximations are close to the solution. For each of the two Chernoff functions, for several initial conditions of different smoothness and for the approximation numbers up to 11, the error corresponding to each approximation is numerically found. This error is understood as the supremum of the absolute value of the difference between the exact solution and its approximating function. As it turned out, in all the cases studied, the error dependence on the approximation number nearly power-law form. This follows from the fact that the dependence of the error logarithm on the logarithm of the approximation number is close to linear. By finding the equation of the approximating line using linear regression, we find the exponent in the power dependence of the error on the approximation number and call it the order of convergence. These orders for all studied initial conditions are compiled in a table. The empirical dependence of the convergence order on the smoothness class of the initial condition is found on the considered family of initial conditions.

Authors: Dziubek Dariusz , Dziubek Karolina
Published: January 2024

The article presents a clinical case of a 62-year-old patient diagnosed with inflammatory amyloid angiopathy after extensive diagnostic imaging and based on the characteristic radiological picture. Inflammatory amyloid angiopathy is a rare condition with intermediate features between the classic form of amyloid angiopathy and primary central nervous system angiitis. Multiple characteristic features suggesting the diagnosis may be seen on brain magnetic resonance imaging. There are no laboratory markers of the disease. Knowledge of this disease is important as it allows for a quick diagnosis and initiation of appropriate treatment. The response to treatment varies, with full symptom resolution in some patients, and resistance to treatment in others, such as the patient described in this case report.
