MACHIAVELLIAN RELATIONSHIP MODEL, LOVE OF MONEY, RELIGIOSITY AND TAX EVASION: MULTI-GROUP ANALYSIS BASED ON GENDER

This study aims to test whether there is an influence of Machiavellian, love of money, and religiosity on tax evasion with gender as a moderating variable. The method in this study is quantitative explanatory type with a correlational approach. The data used is primary data by distributing questionnaires to taxpayers throughout Indonesia using purposive sampling and using the Issac and Michael formula so that 350 respondents were obtained. The analysis technique uses the Partial Least Square Multi-Group Analysis technique (PLS-MGA). The results of the study prove that, first, Machiavellian influences tax evasion, the higher the Machiavellian attitude, the greater the likelihood of tax evasion; Second, love of money influences tax evasion, the higher a person's love of money, tax evasion is considered reasonable. Third, religiosity has no effect. The high or low level of a person's religiosity has not been able to suppress tax evasion. Fourth, Machiavellian influences tax evasion moderated by gender. Machiavellian owned by the male gender is greater than that of the female gender. Love of money owned by men does not affect tax evasion, but becomes a motivation to pursue a career while love of money affects embezzlement moderated by female gender because women have very high needs compared to men. Religiosity affects tax evasion moderated by gender. This means that the higher the level of religiosity of a person, both men and women, are able to suppress tax evasion and people who are more religious tend to be more against tax evasion.

Single-cell analysis of osmoregulation reveals heterogeneity of aquaporin 4 functionality in human astrocytes.

The water channel aquaporin 4 (AQP4) contributes to water flow and waste removal across the blood-brain barrier and its levels, organization and localization are perturbed in various neurological diseases, including Alzheimer's Disease. This renders AQP4 a potentially valuable therapeutic target. However, most functional assays aimed at identifying modulators of AQP4 function are performed with primary rodent cells and do not consider inter-cellular variations in AQP4 abundance and presentation. To address this, we have established and applied a robust live cell microscopy assay that captures the contribution of AQP4 in the osmotically driven (de-)quenching of the vital dye Calcein-AM with single-cell resolution. Using human astrocytoma cells, we found that performing measurements on cellular regions instead of whole fields of view yielded a more sensitive readout of the osmotic response, which correlated with AQP4 abundance. Stable co-expression of the two major AQP4 isoforms, but not of the individual isoforms, provoked a faster adaptation to osmotic changes, while siRNA-mediated knockdown of AQP4 had the opposite effect. Post-hoc correlation with the canonical membrane marker CD44 revealed that the speed of the osmotic response scaled with AQP4 membrane enrichment. Coating the substrate with laminin promoted AQP4 membrane enrichment, while cell confinement with fixed-size micropatterns further increased the speed of osmoregulation, underscoring the influence of extracellular factors. The osmotic response of primary fetal astrocytes and human iPSC-derived astrocyte models was comparable to AQP4-deficient astrocytoma cells, in line with their low AQP4 levels and indicative of their immature state. In conclusion, a correlative single-cell approach based on the quantification of Calcein-AM quenching capacity, AQP4 abundance and AQP4 membrane enrichment, allows resolving osmoregulation in a more sensitive manner and reveals heterogeneity between and within human astrocyte (-like) cultures, which could prove crucial for future screens aimed at identifying AQP4 modulators.

Correlations and Fractality in Sentence-Level Sentiment Analysis Based on VADER for Literary Texts

We perform a sentence-level sentiment analysis study of different literary texts in English language. Each text is converted into a series in which the data points are the sentiment value of each sentence obtained using the sentiment analysis tool (VADER). By applying the Detrended Fluctuation Analysis (DFA) and the Higuchi Fractal Dimension (HFD) methods to these sentiment series, we find that they are monofractal with long-term correlations, which can be explained by the fact that the writing process has memory by construction, with a sentiment evolution that is self-similar. Furthermore, we discretize these series by applying a classification approach which transforms the series into a one on which each data point has only three possible values, corresponding to positive, neutral or negative sentiments. We map these three-states series to a Markov chain and investigate the transitions of sentiment from one sentence to the next, obtaining a state transition matrix for each book that provides information on the probability of transitioning between sentiments from one sentence to the next. This approach shows that there are biases towards increasing the probability of switching to neutral or positive sentences. The two approaches supplement each other, since the long-term correlation approach allows a global assessment of the sentiment of the book, while the state transition matrix approach provides local information about the sentiment evolution along the text.

Hubungan Antara Beban Kerja dan Coping Stress pada Mahasiswa yang Bekerja Secara Part Time

Studying and working are familiar things to encounter nowadays, if you look at the many universities in Indonesia, both public and private, that provide special classes for employees. This phenomenon as a trend chosen by female students is currently motivated by various reasons, for example the problem of financing education or daily needs, to fill free time, or as an option for wanting to live independently so that they are not dependent on their parents for their lives and at the same time being able to lighten the family's burden. Interestingly, among students, most of them are interested in part-time work on the grounds that it is more flexible compared to full-time work, so that students can adjust work schedules and study schedules. Of course, studying and working is not easy because students spend a lot of time studying or just doing assignments from lecturers. The impact of this on students can disrupt learning activities, and judging from the possibility that many students are negligent in carrying out their assignments and it is feared that these students' preoccupation with work will override lectures and their studies will be neglected or even drop out. In carrying out study activities while working, stress coping is needed to handle the workload received, because there is pressure from workload and stress when studying while working. The aim of this research is to look at the relationship between workload and stress coping in students who work part time. This research uses quantitative methods with a correlational approach. There were 96 respondent data collected for processing. Data collection using workload and stress coping scales via Google Forms. The results of the analysis show results (0.008  0.05), meaning that there is a relationship between workload and stress coping in students who work part time. That the higher the perceived workload, the more stress coping behavior will be carried out.

Reduced Cost Computation and Exploitation of Accurate Radial Interaction Potentials for Barrier-Less Processes.

Barrier-less steps are typical of radical and ionic reactions in the gas-phase, which often take place in extreme environments such as the combustion reactors operating at very high temperatures or the interstellar medium, characterized by ultralow temperatures and pressures. The difficulty of experimental studies in conditions mimicking these environments suggests that computational approaches can provide a valuable support. In this connection, the most advanced treatments of these processes in the framework of transition state theory are able to deliver accurate kinetic parameters provided that the underlying potential energy surface is sufficiently accurate. Since this requires a balanced treatment of static and dynamic correlation (which play different roles in different regions), very sophisticated and expensive quantum chemical approaches are required. One effective solution of this problem is offered by the computation of accurate one-dimensional radial potentials, which are then used to correct the results of a Monte Carlo sampling performed by cheaper quantum chemical approaches. In this paper, we will show that, for a large panel of different barrier-less reaction steps, the radial potential is ruled by the R-4 term and that addition of a further R-6 contribution provides quantitative agreement with the reference points. The consequences of this outcome are not trivial, since the reference potential can be fitted by a very limited number of points possibly with a nonlinear spacing. In the case of reaction steps ruled by long-range transition states, generalized expressions are also given for computing reaction rates in the framework of the phase-space theory. All these improvements pave the way toward the computation of reaction rates for barrier-less reactions involving large molecules.

An Integrated Approach to Elucidate the Interplay between Iron Uptake Dynamics and Magnetosome Formation at the Single-Cell Level in Magnetospirillum gryphiswaldense.

Iron is a crucial element integral to various fundamental biological molecular mechanisms, including magnetosome biogenesis in magnetotactic bacteria (MTB). Magnetosomes are formed through the internalization and biomineralization of iron into magnetite crystals. However, the interconnected mechanisms by which MTB uptake and regulate intracellular iron for magnetosome biomineralization remain poorly understood, particularly at the single-cell level. To gain insights we employed a holistic multiscale approach, i.e., from elemental iron species to bacterial populations, to elucidate the interplay between iron uptake dynamics and magnetosome formation in Magnetospirillum gryphiswaldense MSR-1 under near-native conditions. We combined a correlative microscopy approach integrating light and X-ray tomography with analytical techniques, such as flow cytometry and inductively coupled plasma spectroscopy, to evaluate the effects of iron and oxygen availability on cellular growth, magnetosome biogenesis, and intracellular iron pool in MSR-1. Our results revealed that increased iron availability under microaerobic conditions significantly promoted the formation of longer magnetosome chains and increased intracellular iron uptake, with a saturation point at 300 μM iron citrate. Beyond this threshold, additional iron did not further extend the magnetosome chain length or increase total intracellular iron levels. Moreover, our work reveals (i) a direct correlation between the labile Fe2+ pool size and magnetosome content, with higher intracellular iron concentrations correlating with increased magnetosome production, and (ii) the existence of an intracellular iron pool, distinct from magnetite, persisting during all stages of biomineralization. This study offers insights into iron dynamics in magnetosome biomineralization at a single-cell level, potentially enhancing the industrial biomanufacturing of magnetosomes.

Correlative Multi-Scale Characterization of Nanoparticles Using Transmission Electron Microscopy

Chemical and physical properties of nanoparticles (NPs) are strongly influenced not only by the crystal structure of the respective material, including crystal structure defects but also by the NP size and shape. Contemporary transmission electron microscopy (TEM) can describe all these NP characteristics, however typically with a different statistical relevance. While the size and shape of NPs are frequently determined on a large ensemble of NPs and thus with good statistics, the characteristics on the atomic scale are usually quantified for a small number of individual NPs and thus with low statistical relevance. In this contribution, we present a TEM-based characterization technique, which can determine relevant characteristics of NPs in a scale-bridging way—from the crystal structure and crystal structure defects up to the NP size and morphology—with sufficient statistical relevance. This technique is based on a correlative multi-scale TEM approach that combines information on atomic scale obtained from the high-resolution imaging with the results of the low-resolution imaging assisted by a semi-automatic segmentation routine. The capability of the technique is illustrated in several examples, including Au NPs with different shapes, Au nanorods with different facet configurations, and multi-core iron oxide nanoparticles with a hierarchical structure.

Pengaruh budaya organisasi dan komitmen organisasi terhadap kinerja karyawan

Healthcare services in hospitals are a significant concern in Indonesia, where the quality of employee performance is often considered suboptimal. This may be influenced by cultural factors and levels of employee commitment. This study aims to examine the impact of organizational culture and organizational commitment on employee performance in hospitals, both individually and collectively. The research adopts a quantitative correlational approach. Research subjects were selected using purposive sampling techniques, with data obtained from 167 hospital employees in Lamongan. The study utilized scales measuring employee performance, organizational culture, and organizational commitment. Data analysis was conducted using multiple linear regression. The results indicate that organizational culture and organizational commitment together have a significant effect on employee performance, with an F value of 15.864 and a p-value less than 0.000, contributing an effective contribution of 16.2%. However, the partial effect analysis reveals that while organizational culture influences employee performance, organizational commitment does not significantly affect employee performance.

The Influence of Loneliness and Self-Control on Online Game Addiction

The development of information technology has brought various conveniences to everyday life, including easier access to online games. However, a negative impact that is often overlooked is online game addiction which can adversely affect a person's physical, mental and social health. The purpose of this study is to understand the influence of loneliness and self-control on online game addiction in gaming community members. This study used a correlational quantitative approach with 220 research subjects from the online gaming community. This study used the OGA scale from Lemmens (2009) to measure online game addiction variables, UCLA Loneliness Scale Version 3 from Russel (1996) to measure loneliness variables, and Self-Control Scale (SCS) from Tangney (2004) to measure self-control variables. The results showed that there is a significant influence between loneliness and self-control on online game addiction.

Investigating the Impact of Technology Addiction on Early Literacy Skills: A Study of First Graders

This study explores the impact of gadget addiction on the reading abilities of Grade 1 learners, focusing on how technology dependence affects early literacy development. Using a quantitative descriptive correlational approach, the study examined the relationship between gadget addiction and reading proficiency. The findings indicate a minimal and statistically insignificant negative correlation between gadget addiction and reading skills, suggesting that technology use does not significantly impede children's reading development. Despite notable indicators of gadget addiction, such as technology interference in family activities and difficulties in avoiding social media, most learners displayed strong reading and comprehension abilities. The results imply that factors beyond technological dependency, such as educational practices, parental involvement, and individual learner characteristics, may have a more substantial influence on early literacy skills. Consequently, the study concludes that addressing gadget addiction alone may not be sufficient to improve reading abilities. Instead, a comprehensive approach considering various educational and developmental factors should be prioritized. Efforts to enhance early literacy should focus on broader educational strategies, parental guidance, and individualized learner support. The study contributes to ongoing discussions about the balance between technology use and traditional literacy practices in early education, advocating for more holistic approaches to foster reading development in young learners. Future research should explore other contributing factors to literacy achievement, moving beyond the narrow focus on digital device usage.

Biosynthetic enzyme analysis identifies a protective role for TLR4-acting gut microbial sulfonolipids in inflammatory bowel disease

The trillions of microorganisms inhabiting the human gut are intricately linked to human health. While specific microbes have been associated with diseases, microbial abundance alone cannot reveal the molecular mechanisms involved. One such important mechanism is the biosynthesis of functional metabolites. Here, we develop a biosynthetic enzyme-guided disease correlation approach to uncover microbial functional metabolites linked to disease. Applying this approach, we negatively correlate the expression of gut microbial sulfonolipid (SoL) biosynthetic enzymes to inflammatory bowel disease (IBD). Targeted chemoinformatics and metabolomics then confirm that SoL abundance is significantly decreased in IBD patient data and samples. In a mouse model of IBD, we further validate that SoL abundance is decreased while inflammation is increased in diseased mice. We show that SoLs consistently contribute to the immunoregulatory activity of different SoL-producing human microbes. We further reveal that sulfobacins A and B, representative SoLs, act on Toll-like receptor 4 (TLR4) and block lipopolysaccharide (LPS) binding, suppressing both LPS-induced inflammation and macrophage M1 polarization. Together, these results suggest that SoLs mediate a protective effect against IBD through TLR4 signaling and showcase a widely applicable biosynthetic enzyme-guided disease correlation approach to directly link the biosynthesis of gut microbial functional metabolites to human health.

The Relationship Between Nutritional Status And The Development Of Children Aged 4-60 Months

Child development is an important aspect of human life, especially in the early period of life, which is often referred to as the critical or golden period as the child's brain undergoes rapid growth. Developmental disorders in children under five, especially in terms of motor skills, have a long-term impact on their development, and a child's nutritional status has been shown to play a role in the process. Therefore, this study aims to determine the relationship between nutritional status and development of children aged 4-60 months in Jember Regency. The research method used was a quantitative correlational approach with a cross-sectional approach, involving a total of 57 children who had a Kartu Menuju Sehat (KMS) as the population. From the results of the formula calculation, the sample size was determined as 50 respondents using a non-randomized (non-probability) method, namely purposive sampling based on certain criteria. The research instruments involved the Kartu Menuju Sehat (KMS) to assess children's nutritional status and the Developmental Pre-Screening Questionnaire (KPSP) to identify children's development. The results of the chi-square statistical test revealed a significant relationship between nutritional status and development of children aged 4-60 months in Jember District. [ Children with good nutritional status show more optimal developmental progress, while children with poor nutritional status tend to experience slower or inappropriate development for their age. This finding supports theories that emphasize the importance of adequate nutrition for children's growth and development. Therefore, efforts to improve children's nutritional status should be a top priority in various child health and education programs. With the right understanding and action, we can help create a healthier and more potential future generation.

Investigating the Impact of Test Anxiety and Self-Regulation on Foreign Language Learning: A Quantitative Correlational Approach

The present study investigated the self-regulated learning strategies adopted by EFL learners, their levels of cognitive test anxiety, and the potential correlations between self-regulated learning and cognitive test anxiety. The study also examined whether gender and level of language proficiency had a significant effect on self-regulated learning and cognitive test anxiety. A correlational survey design was employed to investigate EFL learners and cross-sectional data were collected through an online questionnaire. Data analysis of 269 undergraduate students revealed that gender consistently emerged as a significant variable. Notably, female students exhibited higher mean scores in both self-regulated learning and cognitive test anxiety. Furthermore, the results consistently found a correlation between self-regulated learning and cognitive test anxiety, with self-regulated learning effectively predicting cognitive test anxiety. Specifically, the predictive power of self-regulated learning for cognitive test anxiety was found to be statistically significant only within the group of students at A2 language level.
