SMARTPHONE ADDICTION AMONG COLLEGE STUDENTS: DO SELF-ESTEEM AND SELF-CONTROL PLAY ROLE?

Smartphone addiction has increasingly emerged as a significant concern among college students. This study aims to investigate the impact of self-esteem and self-control on smartphone addiction within this demographic. Adopting a survey design with a correlational approach, the study involved 130 students selected using convenience sampling. The researchers employed the Smartphone Addiction Scale, Rosenberg Self-Esteem Scale, and Self-Control Scale for data collection. Descriptive statistics were used to examine the variables, followed by hypothesis testing through simple and multiple regression analyses. The results indicate that both self-esteem and self-control negatively affect smartphone addiction, both independently and collectively. Specifically, higher levels of self-esteem and self-control are associated with lower levels of smartphone addiction among participants. This study provides a novel contribution by examining the combined effects of self-esteem and self-control, offering new insights into the roles of these psychological factors in predicting smartphone addiction among Indonesian university students. These findings have significant implications for addressing smartphone addiction through interventions that enhance self-esteem and self-control.

Local Electronic Correlation in Multicomponent Møller-Plesset Perturbation Theory.

We present in this contribution the first application of local correlation in the context of multicomponent methods. Multicomponent approaches allow for the targeted simulation of electrons together with other Fermions (most commonly protons) as quantum particles. These methods have become increasingly popular over the last years, particularly for the description of nuclear quantum effects (in strong hydrogen bonds, proton tunneling, and many more). However, most implementations are still based on canonical formulations of wave function theory, which we know for decades to be computationally inefficient for capturing dynamical correlation effects. Local correlation approaches, particularly with the use of pair natural orbitals (PNOs), enable asymptotically linear scaling of computational costs with very little impact on the overall accuracy. In this context, the efficient use of density fitting approximations in the integral calculation proves essential. We start by discussing our implementation of density-fitted NEO-MP2 and NEO-PNO-LMP2, upgrading the electronic correlation treatment up to PNO local coupled cluster level of theory. Several challenging examples are provided to benchmark the method in terms of accuracy as well as computational cost scaling. Following appropriate protocols, anharmonic corrections to localized X-H stretches can be applied routinely with little computational overhead.

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.

Quantifying the Relation Between Aging-related Trabecular Bone Microstructure and Mechanical Properties with Digital Volume Correlation Approach

Subcortical Alterations in Newly Diagnosed Epilepsy and Associated Changes in Brain Connectivity and Cognition.

Patients with chronic focal epilepsy commonly exhibit subcortical atrophy, particularly of the thalamus. The timing of these alterations remains uncertain, though preliminary evidence suggests that observable changes may already be present at diagnosis. It is also not yet known how these morphological changes are linked to the coherence of white matter pathways throughout the brain, or to neuropsychological function often compromised before antiseizure medication treatment. This study investigates localized atrophy in subcortical regions using surface shape analysis in individuals with newly diagnosed focal epilepsy (NDfE) and assesses their implications on brain connectivity and cognitive function. We collected structural (T1w) and diffusion-weighted MRI and neuropsychological data from 104 patients with NDfE and 45 healthy controls (HCs) matched for age, sex, and education. A vertex-based shape analysis was performed on subcortical structures to compare patients with NDfE and HC, adjusting for age, sex, and intracranial volume. The mean deformation of significance areas (pcor < 0.05) was used to identify white matter pathways associated with overall shape alterations in patients relative to controls using correlational tractography. Additionally, the relationship between significant subcortical shape values and neuropsychological outcomes was evaluated using a generalized canonical correlation approach. Shape analysis revealed bilateral focal inward deformation (a proxy for localized atrophy) in anterior areas of the right and left thalamus and right pallidum in patients with NDfE compared to HC (FWE corrected). No structures showed areas of outward deformation in patients. The connectometry analysis revealed that fractional anisotropy (FA) was positively correlated with thalamic and pallidal shape deformation, that is, reduced FA was associated with inward deformation in tracts proximal to and or connecting with the thalamus including the fornix, frontal, parahippocampal, and corticothalamic pathways. Thalamic and pallidal shape changes were also related to increased depression and anxiety and reduced memory and cognitive function. These findings suggest that atrophy of the thalamus, which has previously been associated with the generation and maintenance of focal seizures, may present at epilepsy diagnosis and relate to alterations in both white matter connectivity and cognitive performance. We suggest that at least some alterations in brain structure and consequent impact on cognitive and affective processes are the result of early epileptogenic processes rather than exclusively due to the chronicity of longstanding epilepsy, recurrent seizures, and treatment with antiseizure medication.

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.
