Authors: Gong Jian , Lv Yinjuan , Meng Yuhao , Zhang Weiheng , Jiang Xiaocui , Xiao Min
Published: August 2024

Prenatal stress can lead to the programming of the neuroendocrine system in male offspring, disrupting the hypothalamic testicular axis and adversely affecting the reproductive health of male offspring. This study aimed to determine the long-term effects of prenatal stress on the KISS1 system in male offspring and the effects on reproductive function in male offspring. Sixteen pregnant females were divided into a prenatal control group (PC, n = 8) and a prenatal stress group (PS, n = 8). The PS group was modeled with chronic unpredictable mild stress (CUMS) from day 1 of gestation to full-term delivery. Differences between the two groups in various maternal parameters, including glucocorticoid secretion, litter size, and the effects of male offspring birth weight, the KISS1 system, and reproductive function, were determined. Male offspring of PS dams had lower birth weights compared to prenatal controls.KISS1 gene expression is reduced at birth and in adult PS offspring, and its receptor KISS1-R protein is similarly reduced in PS offspring at birth and adulthood. In adulthood, PS male offspring show significantly reduced sex hormone production, altered testicular morphology, reduced maturation of their supporting cells, and decreased expression of connexin 43 (CX43), leading to an altered sperm microenvironment and reduced sperm quality. In conclusion, prenatal stress leads to adverse changes in the KISS1 system in male offspring and decreased reproductive function.

Published: August 2024

Inwazyjne zakażenia grzybicze o etiologii Candida spp. wiążą się z dużą śmiertelnością, szczególnie w oddziałach intensywnej terapii (OIT). Tylko połowa infekcji jest wykrywana za życia pacjenta, co sprawia, że jest to jedna z częściej pomijanych infekcji w OIT. Najczęstszym czynnikiem infekcyjnym kandydemii jest Candida albicans, wzrasta jednak liczba innych gatunków o różnym profilu lekooporności. W opisywanym przypadku 73-letni pacjent został przyjęty do Oddziału Intensywnej Terapii z powodu niewydolności wielonarządowej w przebiegu kalectwa dróg żółciowych. Z posiewów krwi z cewnika centralnego, cewnika dializacyjnego oraz krwi z tętnicy uzyskano wzrost szczepu Candida glabrata. Wzrost C. glabrata uzyskano również z ran oraz materiału śródoperacyjnego. W terapii zastosowano mykafunginę w dawce 100 mg.
Le problėme d'objet de lituanica de XVI-XVIII siėcles
Authors: Narbutienė Daiva
Published: August 2024

Dans cet article, il s'agit du sens du terme lituanica. C'est le mot latin qui signifie tout ce qui a trait à la Lituanie, c'est-à-dire tous les éléments ayant des rapports avec la Lituanie. On discute de l'évolution du concept de lituanica dans les travaux de différents auteurs qui se sont occupés de la bibliographie et de la bibliologie. Actuellement, la définition officielle de lituanica est « la littérature imprimée en langue de la Lituanie, mais liée à elle par les auteurs, la langue, le contenu et d'autres aspects ». On aborde également l'objet des livres en langues étrangères de la Lituanie des XVIe-XVIIIe siècles. Le but des historiens du livre de la Lituanie est d'étudier non seulement tout l'héritage culturel en langue lituanienne, mais aussi en langues étrangères : latin, polonais, allemand, biélorusse, etc. Les livres latins de la Lituanie composent la plus grande partie de l'ancien héritage imprimé. À notre avis, les livres créés par des citoyens du Grand-Duché de Lituanie, mais imprimés à l'étranger, ainsi que les livres édités sur le territoire de ce pays, constituent l'objet des études d'histoire du livre ancien de la Lituanie. C'est pourquoi aujourd'hui nous pouvons considérer que le premier livre imprimé de la Lituanie est Agenda sive Exequiale divinorum sacramentorum, préparé par Martinus, le chanoiné de Vilnius, et publié en 1499 à l'étranger. Cela signifie que l'objet de lituanica et l'objet du livre de la Lituanie concordent parfois.

Management and Clinical Outcomes of Neonatal Hypothermia in the Newborn Nursery
Authors: Dang Rebecca , Patel Anisha I. , Weng Yingjie , Schroeder Alan R. , Aby Janelle , Frymoyer Adam
Published: August 2024

OBJECTIVES

Neonatal hypothermia has been shown to be commonly detected among late preterm and term infants. In preterm and very low birth weight infants, hypothermia is associated with increased morbidity and mortality. Little is known about the clinical interventions and outcomes in hypothermic late preterm and term infants. This study fills this gap in the evidence.

METHODS

Single-center retrospective cohort study using electronic health record data on infants ≥35 weeks’ gestation admitted to a newborn nursery from 2015 to 2021. Hypothermia was categorized by severity: none, mild (single episode, 36.0–36.4°C), and moderate or recurrent (<36.0°C and/or 2+ episodes lasting at least 2 hours). Bivariable and multivariable logistic regression examined associations between hypothermia and interventions or outcomes. Stratified analyses by effect modifiers were conducted when appropriate.

RESULTS

Among 24 009 infants, 1111 had moderate or recurrent hypothermia. These hypothermic infants had higher odds of NICU transfer (adjusted odds ratio [aOR] 2.10, 95% confidence interval [CI] 1.68–2.60), sepsis evaluation (aOR 2.23, 95% CI 1.73–2.84), and antibiotic use (aOR 1.73, 95% CI 1.15–2.50) than infants without hypothermia. No infants with hypothermia had culture-positive sepsis, and receipt of antibiotics ≥72 hours (surrogate for culture-negative sepsis and/or higher severity of illness) was not more common in hypothermic infants. Hypothermic infants also had higher odds of blood glucose measurement and hypoglycemia, slightly higher percent weight loss, and longer lengths of stay.

CONCLUSIONS

Late preterm and term infants with hypothermia in the nursery have potentially unnecessary increased resource utilization. Evidence-based and value-driven approaches to hypothermia in this population are needed.

Published: August 2024

In oral implantology, surgeons often confront the need to improve alveolar bone quality and volume before implantation in patients with bone defects. Whereas guided bone regeneration with titanium meshes is a clinical gold standard for bone augmentation, mesh removal pre-implantation presents a drawback. This study explores biodegradable scaffolds as an alternative. The research investigates the impact of various compositions of customized bone-grafting scaffolds on proliferation and osteogenic differentiation processes in vitro. Plates (10 × 10 × 0.5 mm) were fabricated from polylactide (PLA), PLA with 15% hydroxyapatite nanoparticles (PLA/HA), and polylactide with glycolic acid copolymers (PLGA 60:40 and 85:15). Gingival fibroblasts assessed the influence of experimental samples on proliferation and osteogenic differentiation in a low-glucose medium. Osteogenic differentiation was induced, and alizarin red staining measured extracellular matrix calcification via spectrophotometry. Active proliferation of gingival fibroblasts occurred along scaffold edges during cultivation. Although cells proliferated with experimental samples, rates were lower than control cells. PLA/HA showed higher alizarin red staining intensity, indicating enhanced matrix calcification. Experimental samples (PLA, PLA/HA, PLGA 85:15, PLGA 60:40) supported cell proliferation at lower rates than control. PLA/HA demonstrated increased matrix calcification. Biodegradable membranes were nontoxic, suggesting potential for bone augmentation.
VARIANCE-BASED SENSITIVITY OF BAYESIAN INVERSE PROBLEMS TO THE PRIOR DISTRIBUTION
Authors: Darges John E. , Alexanderian Alen , Gremaud Pierre A.
Published: August 2024

The formulation of Bayesian inverse problems involves choosing prior distributions; choices that seem equally reason-able may lead to significantly different conclusions. We develop a computational approach to understand the impact of the hyperparameters defining the prior on the posterior statistics of the quantities of interest. Our approach relies on global sensitivity analysis (GSA) of Bayesian inverse problems with respect to the prior hyperparameters. This, however, is a challenging problem-a naive double loop sampling approach would require running a prohibitive number of Markov chain Monte Carlo (MCMC) sampling procedures. The present work takes a foundational step in making such a sensitivity analysis practical by combining efficient surrogate models and a tailored importance sampling approach. In particular, we can perform accurate GSA of posterior statistics of quantities of interest with respect to prior hyperparameters without the need to repeat MCMC runs. We demonstrate the effectiveness of the approach on a simple Bayesian linear inverse problem and a nonlinear inverse problem governed by an epidemiological model.
Structural characterisation of Eastern Canada’s old industrial masonry buildings via typological analysis: part II – building database analysis
Authors: Davis Lucy , Malomo Daniele
Published: August 2024

The typological analysis conducted in the companion paper is further expanded within this work through the critical analysis of a new extensive building database specifically conceived for old industrial masonry buildings in Eastern Canada. The identification of recurrent unreinforced masonry (URM) building archetypes in this low-to-moderate seismic region is essential to decrease uncertainties currently prevalent in the analysis of local old URM structures, often targeted for adaptive reuse. The database assembled herein comprises various heritage designated buildings across Eastern Canada and was compiled harmonising existing repositories at the federal, provincial and municipal level with an unprecedented focus on structural features. The characteristics of these resources are quantitatively analysed and applied to a case study of the city of Montréal, one of the most important industrial centres in nineteenth and twentieth century Canada. Outcomes from this study will guide practitioners and researchers involved in the structural and seismic assessment and retrofit of old industrial URM constructions, enable more and less invasive rational retrofit designs and inform the new Existing Structures provisions to be included in the 2030 National Building Code of Canada.
Diferente aroma, mismo color floral: el caso de dos especies de Salvia de corola blanca
Authors: Martínez-Díaz Yesenia , Ramírez Reyes Leopoldo , Bedolla-García Brenda , Cuevas Eduardo
Published: August 2024

Background: Plants emit floral signals that are attractive to pollinators. Floral volatile organic compounds (VOCs) are considered a key signal in attracting pollinators. However, it has been scarcely explored whether flowers of the same color emit the same scent.
 Questions: Do different species of Salvia with white corolla flowers emit the same floral scent and attract the same floral visitors?
Study species: Salvia assurgens and Salvia madrigalii, two species with white corolla but different floral morphology.
Study site: Temperate forest southeast of Morelia, Michoacán.
Methods: The floral scent was analyzed by gas/mass chromatography and floral visitor observations were carried out with video cameras.
Results: The chemical profile of floral scent (composition and relative quantity) differed between S. assurgens and S. madrigalii. In S. madrigalii we found 16 VOCs and it was visited exclusively by the hummingbird Amazilia beryllina, and in S. assurgens we found 11 VOCs and it was visited by four species of insects, being the butterfly Thorybes dorantes the most frequent visitor. Canonical correspondence analysis (CCA) showed that floral volatiles were significantly correlated with the visitation rate of floral visitors.
Conclusions: Our study shows evidence that Salvia species with white corolla flowers with different morphology emit different floral scents and attract particular floral visitors.

Extracting Multimodal Surface-Wave Dispersion Curves from Ambient Seismic Noise Using High-Resolution Linear Radon Transform
Authors: Jin Hao , Luo Yinhe , Yang Yingjie , Zhao Kaifeng
Published: August 2024

In the past two decades or so, ambient noise tomography (ANT) has emerged as an established method for imaging subsurface seismic velocity structures. One of the key steps in ANT is to extract surface-wave dispersion curves. The predominant approach for subsurface shear-wave velocity structure inversion involves utilizing fundamental-mode surface waves in ANT. Nevertheless, a notable challenge encountered is the issue of nonuniqueness when employing the dispersion information of fundamental-mode surface waves to invert for shear-wave velocity models. The inclusion of higher-mode dispersion curves in the inversion offers several benefits, including the reduction of nonuniqueness, enhancement of inversion stability, and decreased dependence on the initial model. In this study, we illustrate the applicability of the high-resolution linear radon transform method (HRLRT) for extracting multimodal surface-wave dispersion energy from ambient seismic noise data. We apply HRLRT to both the synthetic noise data and real data recorded by USArray. Our results of applications show that the HRLRT method can extract multimodal surface-wave dispersion information. Compared with established methods such as the frequency–Bessel transform and multicomponent frequency–Bessel transform, the HRLRT exhibits an advantage in suppressing “crossed” artifacts and the second-/third-type artifacts caused by sparse spatial sampling, and the resulting dispersion energy from HRLRT has narrower peaks, meaning high resolution of dispersion curves based on the HRLRT method.
A Benchmarking Method to Rank the Performance of Physics-Based Earthquake Simulations
Authors: Gómez-Novell Octavi , Visini Francesco , Pace Bruno , Álvarez-Gómez José A. , Herrero-Barbero Paula
Published: August 2024

Physics-based earthquake simulators are an increasingly popular modeling tool in earthquake forecasting for seismic hazard as well as fault rupture behavior studies. Their popularity comes from their ability to overcome completeness limitations of real catalogs, and also because they allow reproducing complex fault rupture and interaction patterns via modeling the physical processes involved in earthquake nucleation and propagation. One important challenge of these models revolves around selecting the physical input parameters that will yield the better similarity to earthquake relationships observed in nature, for instance, the frictional parameters of the rate-and-state law—a and b—or the initial normal and shear stresses. Because of the scarcity of empirical data, such input parameters are often selected by trial–error exploration and predominantly manual model performance analyses, which can overall be time consuming. We present a new benchmarking approach to analyze and rank the relative performance of simultaneous earthquake simulation catalogs by quantitatively scoring their combined fit to three reference function types: (1) earthquake-scaling relationships, (2) the shape of the magnitude–frequency distributions, and (3) the rates of the surface ruptures from paleoseismology or paleoearthquake occurrences. The approach provides an effective and potentially more efficient approximation to easily identify the models and input parameter combinations that fit more closely to earthquake relations and behavior. The approach also facilitates the exhaustive analysis of many input parameter combinations, identifying systematic correlations between parameters and model outputs that can potentially improve the overall understanding of the physics-based models. Finally, we demonstrate how the method results agree with the published findings in other earthquake simulation evaluations, a fact that reinforces its overall usefulness. The model ranking outputs can be useful for subsequent analyses, particularly in seismic hazard applications, such as the selection of appropriate earthquake occurrence rate models and their weighting for a logic tree.
Shallow Structure and Seismic Amplification Effects in the Weifang Segment of the Tanlu Fault Zone Based on the Spectral Ratio Method
Authors: Zhou Guili , Yao Huajian
Published: August 2024

The Weifang segment of the Tanlu fault zone (TLFZ) is located in the central section of the TLFZ, eastern China, and has been identified as an earthquake gap zone. Previous studies in the region have mainly focused on the crustal velocity structure and anisotropy, with limited attention to the shallow near-surface structures. In this study, we analyzed the distribution of sediment thickness and evaluated the seismic amplification effects in the Weifang segment of the TLFZ using the horizontal-to-vertical spectral ratio (HVSR) method and the standard spectral ratio (SSR) method. The data we used are from a dense array of 302 three-component seismometers deployed in 2017 for three months. The lowest peak frequency of HVSR indicates that the northwestern part of the study area exhibits relatively thicker sedimentary deposits, estimated to be 800–1200 m in thickness, consistent with both tomographic and geological studies. The SSRs are calculated from 43 regional and teleseismic earthquakes with respect to 12 reference stations. The results from SSR show strong amplification in the 0.2–2 Hz frequency range for sites on the northwestern part, and the amplitude can be up to 15 times larger than that of the bedrock site. We also find significant amplification effects as well as thick sedimentary layers at specific stations along the eastern branch of the TLFZ, suggesting a localized low-velocity zone along the fault. Our results also demonstrate that using the single-site seismic method can provide new constraints on the fine structure and site responses of the fault zone, which are important for seismic hazard assessment.
Homo Creator and Creative Machines
Authors: Makocka-Wojsiat Katarzyna
Published: August 2024

The article analyzes the issue of machine creativity in the context of human creativity and questions the cultural consequences of integrating artificial intelligence into the domain of creative activities. Using examples such as creative adversarial networks (CAN) creating graphics and the poetry-generating algorithm code-davinci-002, the machine creative process is discussed. It is highlighted that artificial intelligence systems have the capability to act creatively and generate original solutions, texts, music, and images. However, humans are the source of creative intent and the ones who assign meaning and status to art. Machines currently play an increasingly significant role in creative processes, which could lead to the emergence of new art forms but also poses the risk of automating the aesthetic realm.

Published: August 2024

This study was carried out to determine the biology of Xylocoris flavipes Reuter (Heteroptera: Anthocoridae), an important predator of stored product pests, and its prey preference on some warehouse pests. The study was conducted under laboratory conditions at 25±2ºC temperature and 55±10% humidity. Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs were used to determine the biology of X. flavipes. E. kuehniella, Tribolium confusum Jacquelin du Val (Coleoptera: Tenebrionidae), and Trogoderma granarium Everts (Coleoptera: Dermestidae) larvae were utilized to detect the prey preferences of X. flavipes. The mean development time (days) of five nymphs, female and male adults of Xylocoris flavipes on E. kuehniella eggs were as follows: 4.2±0.63; 3.1±0.57; 2.9±0.57; 3.0±0.00; 4.5±0.53; 104.2±17.01; 114.6±12.34, respectively. The average egg consumption for the aforementioned stages was: 5.0±1.76; 9.9±3.07; 9.1±6.01; 13.3±4.14; 22.5±4.79; 515.6±75.46; 286.2±24.39, respectively. Although mature male X. flavipes survived longer than females, females consumed more E. kuehniella eggs than males. The mean oviposition period of the females was 36.7±12.39 days, and the average laid egg number was 117.3±29.86. The consumed E. kuehniella eggs and larvae, T. confusum, and T. granarium larvae during the predator nymph period were on average 63.1±6.01; 49.6±2.76; 26.8±3,52; 12.8±4.29, respectively. The average development time (days) of the nymphs for the aforementioned consumption stages were 16.4±1.96; 15.4±0.52; 16.2±1.14; 21.6±4.62, respectively. The consumed E. kuehniella eggs and larvae, T. confusum, and T. granarium larvae during the predator adult period were on average 570±231.32; 249.5±142.10; 218.1±110.57; 22.2±6.23, respectively. The average development time (days) of the adults for the aforementioned consumption stages were 87.5±30.92; 75.9±41.18; 89.3±43.55; 24.5±7.18 days, respectively. X. flavipes preferred mostly E. kuehniella eggs among the preys during the nymph and adult stages, and least T. granarium larvae.

Authors: Gencer Murat , Gök Mustafa , Celik İsmail
Published: August 2024

Soil management techniques can have varying effects on various soil properties. This study investigated the impact of various tillage techniques on soil properties for 14 years. The experiment was conducted at the Çukurova University Research Station, located in a region with a dominant Mediterranean climate. The research aimed to assess the changes in soil organic matter (SOM) content, soil respiration (SR), dehydrogenase enzyme activity (DHA), and soil temperature (ST) under seven different long-term tillage practices. The results revealed significant increases (p ≤ 0.05) in SOM (17-115%), SR (19-37%), and DHA (63-142%), under conservation tillage compared to conventional tillage practices. Additionally, conventional tillage with stubble burned consistently had the lowest values across all measured properties. Seasons variations also significantly (p≤0.05) affected the observed values. These findings suggest that conventional tillage practices have a negative effect on the analyzed biological activities, with stubble burning further exacerbating this impact. Further research exploring the long-term effects of different tillage practices under varying crop rotations and soil conditions can contribute to the sustainable development of agricultural production in the region.
Allelopathic Effects of Black Radish (Raphanus sativus L. var. niger J. Kern.) and Garden Cress (Lepidium sativum L.) Plants on Johnsongrass (Sorghum halepense (L.) Pers.) Plant in Tomato Cultivation
Authors: Elsekran Muhammad , Üstüner Tamer
Published: August 2024

This study aimed to investigate the effectiveness of black radish and garden cress as pre-plant in field trials and their aqueous extracts under greenhouse conditions to control johnsongrass. In the field experiment, black radish and garden cress were grown as a pre-plant, then mixed with the soil and used with and without mulch against johnsongrass. The effects of these applications on johnsongrass development and tomato yield and quality were evaluated. Different concentrations of pre-plant extracts (2, 5, and 10%) were also investigated on johnsongrass and tomato seedling growth in greenhouse conditions. The lowest johnsongrass density was recorded in black radish and garden cress with mulch (106.7 and 97.2 number m-2). Black radish and garden cress with mulch achieved johnsongrass control efficiency of 80.2 and 84.0% compared to those without mulch 56.8 and 58.2%. The effect of all treatments was positive in increasing the quantity and improving the quality of tomato production. The results of greenhouse experiments showed that high concentrations (10%) of black radish and garden cress extracts achieved high levels in preventing the germination and growth of johnsongrass. In these treatments, johnsongrass seeds and rhizomes germination rates were 17.5 and 7.5%, 20.0 and 12.5% respectively. GC-MS analysis showed that five isothiocyanates (ITCs) were in black radish, and their total percentages were 40.4%. In the garden cress, it was found that there is only one ITC with a percentage of 61.0%. Black radish and garden cress effectively inhibit the germination and growth of Johnsongrass due to their allelopathy effects. Sustainable management of johnsongrass can be achieved by introducing these plants into a crop rotation which may be an alternative or reduce the use of herbicides.

Research aims: This research assessed the struggles of the village-owned enterprise of Raknamo Village in Kupang Regency, East Nusa Tenggara Province, to enhance performance.Design/Methodology/Approach: This research used a qualitative approach consisting of stages, such as data collection, data reduction, data display, and conclusion drawing. It collected data through in-depth interviews, non-participant observation, and document review. It analyzed data on performance indicators: resource provision, task implementation, outputs, and goal attainment that the village-owned enterprise struggles to accomplish.Research findings: This research uncovered that the village-owned enterprise of Raknamo Village faces difficulties even now, thus generally performing low in its efforts to provide resources needed, such as personnel, finances, and facilities, implement tasks, produce outputs/products, and attain goals. Specifically, it performed relatively well in renting tents and chairs, increasing little profit; however, it performed poorly in the savings and loan business and traditional weaving home industry, thus experiencing financial loss. The primary factors affecting such performance were the core managers' low managerial and entrepreneurial skills, financial inability and low cooperative attitude of the village society to repay loans, inability of village society to do profitable business, and low income.Theoretical contribution/Originality: This research evaluated the struggles of the village-owned enterprise of Raknamo Village in Kupang Regency to boost performance, which prior studies have not widely investigated. Theoretically, this research is expected to add specified academic or analytical insight into the village-owned enterprises struggling as small business organizations to improve performance.Practitioner implication: The finding has profound implications that eliminating difficulties that hinder the village-owned enterprise’s performance and building its ability to perform better hereafter are both necessary. To reach this expectation, the government should create a capacity-building program for the village-owned enterprise.

This test used the ANOVA analysis tool with Repeated Measurement.Research findings: This research provides results that the information asymmetry variable had a positive effect on the emergence of budgetary slack, while the variables of strategy, incentive scheme, and the interaction of each variable have not proven to influence the emergence of budgetary slack.Theoretical contribution/Originality: The experimental findings support the agency problem that arises from information asymmetry.Practitioner/Policy implication: By using practitioners conditioned in specific budgeting situations in experimental budget studies, this research provides practical implications for budgeting problems in business practice. In particular, it provides an overview of the factors that can influence budget gaps, and in this case, a business can condition its efforts in taking advantage of conditions to create the right budget. Apart from that, this research will be able to provide an overview of what treatments can encourage motivation and increase opportunities for the tendency to create budget slack.Research limitation/Implication: This study was limited to certain company sectors, and there is the possibility of a gap in understanding and interpreting the experimental scenario.
The market reactions for deferred compliance of IAS 41: an analysis of the agriculture sector in Indonesia
Authors: Wahyuni Ersa Tri , Lucin Sandra Trianadewi , Azhar Zubir
Published: August 2024

Research aims: This study aims to investigate the market reaction of post-IAS 41 implementation in Indonesia. IAS 41 Agriculture requires companies to measure biological assets at fair value, which will increase asset values and profit in the first year of its implementation. The increase in the asset values can have a favorable impact on companies’ share prices as fair value was not applied in Indonesia prior to the adoption of IAS 41. In addition, this study analyzes the disclosure compliance of IAS 41 in the interim reports during the implementation year.Design/Methodology/Approach: This study used non-parametric statistics, precisely the Wilcoxon Signed Rank Test and content analysis of financial statement disclosure about IAS 41 Agriculture. The sample of the study comprised 27 Indonesian companies with agriculture assets during the first year of the implementation of IAS 41. Research findings: The results of this study suggest no significant difference in market abnormal return after the first annual financial statements post-IAS 41 implementation were released in the first quarter of 2018. The results also indicate that at least 50% of the 27 sample companies did not use fair value for their biological assets in their first quarter of interim report during the implementation year. The use of fair value was only observed in the last quarter of 2018, as most companies made an effort to apply fair value. The late implementation of fair value in IAS 41 may explain the insignificance of the market's abnormal return reaction in the first quarter of the adoption year when the financial reports were released.Practitioner/Policy implication: The adoption of the new standard requires companies to comply with it right in the first quarter of the implementation year. The capital market regulator should impose stricter requirements for listed companies to apply the new standard starting with the first quarter of financial reports.Research limitation/Implication: The limitations of this study concern the observation period used for calculating abnormal returns, which did not conclude a ‘pure’ market reaction, and the sample of this research was limited to three industries: agriculture, basic chemicals, and consumer goods.

Authors: Ningsih Melly Agustina , Ruwanti Gemi
Published: August 2024

Research aims: This research investigates the determinants of corporate tax management practices through an empirical analysis. It examines the influence of various factors, including profitability, leverage, capital intensity ratio, presence of independent commissioners, firm size, and access to tax facilities.Design/Methodology/Approach: Multiple linear regression analysis was employed as the research methodology. The study focused on manufacturing companies in the basic industrial and chemical sectors listed on the Indonesia Stock Exchange during the period from 2018 to 2021, utilizing a purposive sampling approach—the final sample comprised 18 companies that met the specified criteria.Research Findings: The results indicated that profitability and tax facilities exhibited a negative impact on tax management, while leverage had a positive influence. Conversely, the capital intensity ratio, presence of independent commissioners, and company size did not significantly affect tax management.Theoretical Contribution/Originality: Effective tax management can enhance company compliance with tax obligations and mitigate the likelihood of aggressive tax strategies.Practitioner/Policy Implications: This research provides a valuable benchmark for companies to implement sound tax management practices aligned with tax regulations. Additionally, it offers insights for policymakers to refine tax regulations accordingly.

Authors: Rochimah Ainun , Yuliana Indah
Published: August 2024

Research aims: This study analyzes the differences in market reaction towards eleven sectors in the Indonesia Stock Exchange (IDX) during the political event, i.e., the announcement of the Indonesian presidential and vice-presidential nominees in 2023.Design/Methodology/Approach: This study applied the event study method with indicators of abnormal return, trading volume activity, security return variability, and bid-ask spread. The hypothesis test was a non-parametric test by Wilcoxon Signed Rank Test with a window period of seven days of observation (-3, 0, +3).Research findings: The Wilcoxon Signed Rank Test results revealed a mixed reaction by eleven sectors in IDX to this political event, in which there was a difference and no difference in the reactions.Theoretical contribution/Originality: This study contributes to providing insight into the reaction of eleven different sectors in the IDX to the different announcements of the Indonesian presidential and vice-presidential nominees in 2023. Previous research usually focused on stock indices or only testing one particular sector. Hence, this study investigated eleven sectors in the capital market to compare the different reactions and to expand the results.Practitioner/Policy implication: Research on capital market reactions to political events provides important information for investors to make investment decisions based on investor sentiment that assesses the electability of prospective heads of state to advance the Indonesian economy.Research limitation/Implication: The scope of this study is the announcement of the Indonesian presidential and vice-presidential nominees in 2023; future researchers can continue research on capital market reactions to the Indonesian presidential election 2024 events and add relevant variables, such as foreign sales and foreign buys.
Who emits more emission? the association between CO2 emissions and socio-economics characteristics of Indonesian household

Much research has been done on identifying socio-economic household links in developed countries. However, the study of household carbon emission (HCE) levels and related variables still needs to be examined, especially in developing countries. The study uses an ordinary least squares model to pinpoint the socio-economic elements that affect a household's carbon emission levels. SUSENAS (National Socio-economic Survey) data from March 2019 and 2021, covering 655,694 households, were used. This study used ordinary least squares (OLS) for the regression and dominance analyses (DA) to determine the most crucial factors affecting the HCE. The household characteristics, individuals, and residential conditions are used to measure socio-economic situations. The DA analysis shows that income and household size are the most crucial determinants of HCE. The OLS analysis reveals that the income variable exhibits a non-linear relationship with HCE as an inverted U-shape in the total HCE and most consumption categories. Wealthier households generate higher levels of household carbon emissions than poorer households. The variable of household size demonstrates a positive relationship with the HCE. The composition of household members also significantly affects household carbon emission levels, where the presence of working members and toddlers tends to increase household carbon emissions. The research also finds differences in consumption patterns between urban and rural households, resulting in varying levels of carbon emissions. The findings of this study can assist policymakers in formulating targeted policies to reduce household carbon emissions.

Published: August 2024

Poverty in Indonesia is a problem that needs special attention by the government. Poverty is due to the high level of inequality, unequal distribution of income, and the number of poor people, which continue to increase. Therefore, it can affect society’s economy. This research aims to identify incongruities between endogenous and exogenous variables that influence poverty levels in Indonesia. By applying a descriptive quantitative analysis approach for 2013-2022 in the form of secondary data from the Indonesian Central Statistics Agency, the research model uses dynamic panel data regression analysis based on the Generalized Method Of Moment method (GMM). The method was developed by Arellano-Bond, of which the two best models are First-Difference GMM and System GMM, which create an impartial, consistent, and efficient model for determining short-term ang long-term effects. The research results show that HDI has a significant negative impact on short-term and long-term relationships with poverty levels, resulting in low human resources. Exports have a significant negative impact on poverty levels in the short and long term. This means that if exports increase, poverty levels can be reduced. Imports have a significant positive impact on short-term and long-term with poverty levels. In import activities, the higher the price increases, the more people's purchasing power decreases. The results are declared to have a significant effect because the p-value is significance of level 5% or 0.05. It is expected that the research will become reference material for macroeconomic development and further research regarding poverty alleviation.
Inclusive economic growth and fiscal intervention: could it reduce poverty, inequality, and unemployment in East Java?
Authors: Purwanti Dyah
Published: August 2024

Before the COVID-19 pandemic, East Java Province (then abbreviated to East Java) made remarkable achievements in economic growth accompanied by a continuing downward trend in poverty. Then, after the COVID-19 pandemic broke out in 2020, it had a detrimental impact in terms of health, economics and social aspects. Specifically for East Java, the outbreak caused a severe contraction in the economy and significantly increased the number of local unemployed. However, long before COVID-19, East Java was facing wide inequality. Based on these problems, this study evaluates whether inclusive growth and local government fiscal intervention are solutions. These two factors have been recommended by economist as an effective strategies for reducing the triple problem in East Java. Fiscal intervention is interpreted as expenditure policies in economic, education, and health functions. Using panel data regression during 2015-2021, the study documents that economic growth in East Java still needs to be fully inclusive. This is based on the finding that inclusive economic growth does not simultaneously reduce triple problems (poverty, inequality and unemployment). Inclusive growth reduces poverty in East Java, but it has the opposite effect on unemployment and inequality. On the one hand, positive findings are documented in which fiscal intervention in education spending plays a significant role in reducing poverty. Unfortunately, this study failed to find the determining factors that provide a solution to inequality and unemployment in East Java. These evidences certainly have implications for reviewing the quality of inclusive growth and local government expenditure policies.
