Authors: Widarwati Estu , Nugraha Muhamad Mugi , Nurmalasari Nunik , E. Wityasminingsih E. Wityasminingsih
Published: May 2024

Corporate performance is an achievement of success from a series of corporate activities in several predetermined strategies. Investing in goods and capital increases the firm's value and therefore the firm's performance will be different during the economic crisis and normal conditions. The study aims to examine the relationship between corporate investment and corporate performance. Furthermore, this study also does a different test of the corporate investment effect on corporate performance between the normal and crisis periods. We use the Capital Expenditure and Net Working Capital as measurements of corporate investment and firm performance proxied by operating profit margin. The sample used are 243 non-financial industries firms listed on the Indonesia Stock Exchange (IDX) for the 2017-2021 period, then there is 1215 observation data. The data were analyzed descriptively, and then panel data regression was used for testing the hypotheses. The results showed that the company's investment had a positive effect on the company's performance and there was a significant difference in these influences in both normal and crises periods. This finding has implications that companies can continue investing to improve their performance with economic growth as main consideration for investment decision-making.

Published: May 2024

Banks are institutions with stringent regulations related to corporate governance implementation and the demand for high financial performance. Macroeconomic conditions significantly affect the financial performance, including profitability, of banks. The study focused on Indonesia's four state-owned banks, Bank Tabungan Negara (BBTN), Bank Negara Indonesia (BBNI), Bank Rakyat Indonesia (BBRI), and Bank Mandiri (BMRI). The research sample or saturated sample was the entire population. The 10-year observation period ran from 2011 to 2020. The panel data regression model with a common effect was used to evaluate the data. The data showed that CGPI and LDR had no discernible impact on profitability. While NPL and FOREX had a large negative impact on profitability as evaluated by ROA, CAR, NIM, SIZE, and BIRATE had a significant positive impact. All independent factors simultaneously have a major impact on profitability. All independent factors were able to explain their impact on profitability to a degree of 94.39%, according to adjusted R-squared, while other variables outside the model were responsible for the remaining effects.
Earnings Management and Tax Minimization: Comprehensive Analysis of Book-Tax Differences in Indonesia
Authors: Hashfi Muhammad Hammam Al , Martani Dwi
Published: May 2024

The research aims to investigate the relationship between earnings management strategies, specifically Accrual Earnings Management (AEM) and Real Earnings Management (REM), and abnormal book-tax differences (ABTD). A quantitative approach was employed, utilizing multiple regression models, descriptive statistics, model testing, classical assumption testing, and hypothesis testing through Eviews 12 software on a sample of 671 observations from 61 companies listed on the IDX from 2011 to 2021. The results reveal a significant positive relationship between ABTD and both AEM and REM through overproduction. However, no significant relationship was found between REM and abnormal operating cash flow. Interestingly, a strong negative correlation was discovered between tax avoidance and earnings management through discretionary spending. These findings suggest that accrual management practices are associated with higher levels of tax avoidance, while discretionary spending for earnings management tends to decrease it. The implications of this study provide insights into potential earnings management techniques that can enhance corporate efforts to reduce tax payments and maximize profits while serving as a warning for potential tax avoidance activities.

Visions of augmented reality in popular culture: Power and (un)readable identities when the world becomes a screen
Authors: Gunderson Marianne
Published: May 2024

Augmented reality, where digital objects are overlaid and combined with the ordinary visual surface, is a technology under rapid development, which has long been a part of visions of the digital future. In this article, I examine how gaze and power are coded into three pop-cultural visions of augmented reality. By analysing representations of augmented reality in science fiction through the lens of feminist theory on performativity and intelligibility, visibility and race, gendered gaze, and algorithmic normativity, this paper provides a critical understanding of augmented reality as a visual technology and how it might change or reinforce possible norms and power relations. In these futures where the screen no longer has any boundaries, both cooperative and reluctant bodies are inscribed with gendered and racialised digital markers. Reading visions of augmented reality through feminist theory, I argue that augmented reality technologies enter into assemblages of people, discourses, and technologies, where none of the actors necessarily has an overview. In these assemblages, augmented reality takes on a performative and norm-bearing role by forming a grid of intelligibility that codifies identities, structures hierarchical relationships, and scripts social interactions.

Carbohydrate reserves play a vital role in plant survival during periods of negative carbon balance. Under a carbon-limited scenario, we expect a trade-offs between carbon allocation to growth, reserves, and defense. A resulting hypothesis is that carbon allocation to reserves exhibits a coordinated variation with functional traits associated with the ‘fast-slow’ plant economics spectrum. We tested the relationship between non-structural carbohydrates (NSC) of tree organs and functional traits using 61 angiosperm tree species from temperate and tropical forests with phylogenetic hierarchical Bayesian models. Our results provide evidence that NSC concentrations in stems and branches are decoupled from plant functional traits. while those in roots are weakly coupled with plant functional traits. In contrast, we found that variation between NSC concentrations in leaves and the fast-slow trait spectrum was coordinated, as species with higher leaf NSC had trait values associated with resource conservative species, such as lower SLA, leaf N, and leaf P. We also detected a small effect of leaf habit on the variation of NSC concentrations in branches and roots. Efforts to predict the response of ecosystems to global change will need to integrate a suite of plant traits, such as NSC concentrations in woody organs, that are independent of the ‘fast-slow’ plant economics spectrum and that capture how species respond to a broad range of global change drivers.

Background. The widespread use of dental implants as a predictable treatment choice has drawn attention to their complications as a major challenge despite their high clinical success rates. In this context, loosening of the abutment screw in posterior single crowns is the most common problem; the use of adequate preload and proper anti-rotational features at implant‒abutment interface appear to be two main solutions to such a problem. The present study evaluated the effect of implant‒abutment connections in four different implant systems before and after cyclic loading. Methods. Intra-Lock, Dentis, Xive, and Dio implant systems were used in this study. Each system underwent one million cycles of dynamic forces eight times with a magnitude of 110 N. For each specimen after tightening the screw with a torque of 32 Ncm, the detorque values were measured and recorded by a digital torquemeter after and before cyclic loading. Data were analyzed by Kolmogorov-Smirnov, Levene’s, one-way ANOVA, and post hoc Tukey tests. Results. Initial detorque values between the study groups showed significant differences (P<0.0001). Pairwise comparisons showed significantly lower primary detorque values in the Dentis system compared to the three other systems (P<0.0001). After cyclic loading, significant differences were observed between the study groups (P<0.0001). Pairwise comparisons of the groups showed significant differences between all the systems after loading. Conclusion. The type of implant‒abutment connection is an essential factor influencing the amount of abutment screw loosening.

Published: May 2024

Background. This study aimed to systematically and comprehensively review the effect of various treatment variables on apically extruded debris (AED) during non-surgical root canal retreatment (NSRCRT). Methods. The study protocol is shared in the Open Science Framework database (https://osf. io/kjtdg/?view_only=17060180705745ec9dae9a01614f3880). An electronic search was conducted up to July 2022 to reveal related studies. Two reviewers critically assessed the studies for eligibility against inclusion and exclusion criteria and data extraction. Quantitative data synthesis was performed, and the risk of bias in the studies was also evaluated. Results. Forty-six studies were included in the systematic review and 14 in the meta-analysis. Conflicting or limited evidence was found for the effect of sealer type, obturation technique, and solvent use. The manual instrumentation increased the amount of AED compared to rotary instrumentation during the removal of filling materials (P<0.001). There was no significant difference in the amount of AED between the use of rotary and reciprocating files during the removal of filling materials (P=0.181). Conclusion. Rotary instruments can be recommended instead of manual instruments during the removal of filling materials to control the amount of AED. Further studies with a low risk of bias are needed to clarify the effect of other treatment variables on AED during NSRCRT.

Published: May 2024

Background. In recent years, fluoride concentrations in toothpaste for children and adults have increased. However, the effects of different concentrations on bacterial activity have rarely been compared. We aimed to investigate and compare the antibacterial activity of children’s and adults’ toothpaste containing 500, 1000‒1100, and 1450‒1500 ppm fluoride. Methods. Three strains of bacteria (Streptococcus mutans, Streptococcus salivarius, and Lactobacillus casei) were cultured in brain heart infusion agar. Thirty commercially available toothpaste products for children and adults containing 500, 1000‒1100, and 1450‒1500 ppm fluoride were selected and tested. Toothpaste’s ability to inhibit bacterial growth was evaluated by agar diffusion assay, in which plates were incubated for 24 hours, and then the diameter of the microbial inhibition zone was measured. Comparisons between children’s and adults’ fluoride toothpastes were made using the Mann-Whitney U test. The association between bacterial growth inhibition and sodium lauryl sulfate (SLS) was analyzed by the chi-square test. A P value of <0.05 was considered statistically significant. Results. No difference in the inhibition zone was observed for different fluoride concentrations. However, there were significant differences between toothpastes for children and adults, with higher inhibition zones for adults’ toothpastes. Most toothpastes for adults contained SLS, which was associated with antibacterial activity. Conclusion. Fluoride concentrations ranging from 500 to 1500 ppm did not affect bacterial growth. The antibacterial activity of toothpastes for adults was significantly higher than that of toothpastes for children, which was mainly attributed to the SLS usually added to adult formulations.

Published: May 2024

Background. The present study investigated the skeletal and dental effect in class II division I growing patients due to mandibular deficiency treated with the hybrid aesthetic functional (HAF) appliance. Methods. A sample of 16 growing patients (5 boys and 11 girls; mean age: 9.50 years, standard deviation: 1.15) with class II division I malocclusion were treated using the HAF appliance for an average period of 10±3 months. For each patient, a cephalometric radiograph was taken before and after treatment, and digital analysis was applied using the WebCeph program. The statistical analysis was performed to evaluate dental and skeletal changes associated with the HAF appliance and determine if there were any statistically significant variations in anatomical measurements between the start and completion of the treatment. Results. The data showed a significant increase in SNB angle (P=0.002), leading to a significant decrease in ANB angle (P=0.001). The mandibular length significantly increased (P=0.008), the lower incisors were flared significantly (P=0.028), and the lower molars were extruded significantly (P≤0.001). Also, this study revealed a significant decrease in Wits appraisal (P≤0.001), overjet (P≤0.001), and overbite (P=0.041). Additionally, a significant increase in lower anterior facial height (P≤0.001), total facial height (P=0.001), and posterior facial height (P=0.037) were observed. Conclusion. The HAF appliance showed that it could be used to correct class II division 1 skeletal discrepancy by mandibular advancement. The HAF appliance increased all facial heights significantly.
