The perception and association between depression and academic stress among female undergraduate nursing students: a cross-sectional study
Authors: Andargeery Shaherah Yousef 
Published: June 2024

IntroductionAcademic demands and stressors put nursing students at increasing risk of depression. The aims of the study examine the perceived level of depression and academic stress and investigate the association between these variables among nursing students in Saudi Arabia.MethodsA cross-sectional design was used in this study. Data was collected using depression subscale from DASS-21 scale and the Academic Stress Inventory scale.ResultsA total of 237 students participated in the study. Nursing students perceived normal to mild levels of depression. Students perceived moderate levels of academic stress in all subscales, except for time management and test stress which were high. All academic stress subscales had a positive statistically significant correlation with depression. The regression model explains 49.0% of the variance in the depression scale and indicated that the main significant predictor of depression is studying in group stress, followed by self-inflected stress, study year, and sleep problem. The mean score of depression for first year students was significantly different than students in other study years.DiscussionNurse educators should facilitate group formation and teach students about time-management, problem-solving, negotiation, and coping strategies to deal with academic expectations and demanding situations. Understanding the causes, limiting the exposure to negative influences, and seeking support as needed are important. To enhance the quality of sleep, students should maintain a consistent sleep schedule, while avoiding stimulating activities before bedtime. Future research should focus on a longitudinal study and other variables such as quality of life, satisfaction with the quality of teaching, and support from others.

IntroductionThere is scant empirical work on associations between current and past cannabis use and parenting skills in parents of young children. As recreational cannabis use is now legal in nearly half of states in the U.S., cannabis use is becoming more ubiquitous.MethodsIn the current study, parents of toddler and pre-school age children were randomly assigned to participate in an app-based parenting skills program that included telehealth coaching (Family Check-Up Online; FCU-O), with a focus on parenting in the context of substance use. We aimed to test associations between adolescent-onset and current cannabis use and parent mental health and parenting skills, as well as whether effects of the FCU-O on parent mental health outcomes varied as a function of past cannabis use. Participants were 356 parents of children ages 1.5–5 participating in a randomized controlled trial of the FCU-O. Parents screened into the study if they reported current or past substance misuse or current depressive symptoms. After completing a baseline assessment, parents were randomly assigned to the FCU-O or control group and completed a follow-up assessment 3 months later. Parents retrospectively reported on the age when they initially used substances, as well as their current use.ResultsAfter accounting for current cannabis use, adolescent-onset cannabis use was significantly associated with higher symptoms of anxiety and depression, but not with parenting skills. Adolescent-onset cannabis use was found to significantly moderate the effect of the FCU-O on parents' anxiety symptoms. Specifically, the FCU-O was particularly effective in reducing anxiety symptoms for parents with adolescent-onset regular cannabis use, after accounting for current cannabis use.DiscussionAdolescent-onset regular cannabis use may be a risk factor for later mental health challenges in parents of children under 5. An app-based parenting intervention may be particularly helpful in reducing symptoms of anxiety for parents who used cannabis regularly as adolescents. The findings have significant implications for the prevention of multigenerational risk for substance use and mental health challenges.

Background and Objectives: Coadministration of natural products to enhance the potency of conventional antirheumatic treatment is of high interest. This study aimed to assess the impact of administration of silymarin (a nutritional supplement) in patients with active rheumatoid arthritis under treatment with conventional disease-modifying antirheumatic drugs. Materials and Methods: One-hundred and twenty-two patients diagnosed with active rheumatoid arthritis and treated with conventional disease-modifying antirheumatic drugs were randomly assigned to either control or intervention groups; the latter was supplemented with silymarin (300 mg/day) for 8 weeks. Indicators of disease activity, inflammatory markers, disease activity and disability indices, European League Against Rheumatism responses, fatigue, depression, and anxiety scores were determined at baseline and week 8. Results: Silymarin supplementation significantly reduced the number of tender and swollen joints, duration of morning stiffness, severity of pain, disease activity and disability indices, European League Against Rheumatism responses, levels of fatigue, depression, and anxiety. According to our results, silymarin substantially improved patients’ general condition. Conclusions: Our study provides evidence for the benefits of silymarin supplementation to disease-modifying antirheumatic drugs in patients with active rheumatoid arthritis.

Целью данной работы является повышение эффективности работы схемы прерывистого приема, используемой для энергосбережения пользовательского оборудования в системах беспроводной мобильной связи пятого поколения 5G стандарта New Radio (NR), начиная с первого релиза (Release 15). Во второй части статьи проведен анализ энергоэффективности предложенных в первой части алгоритмов методом имитационного моделирования на системном уровне для различных моделей трафика и наиболее важного сценария развертывания систем беспроводной мобильной связи 5G в городских условиях. Анализ результатов моделирования показал, что предложенные способы адаптации схемы прерывистого приема к поступающему трафику дают значительный выигрыш в энергосбережении (до 70%) для всех типов трафика данных с низкой загрузкой частотно-временных ресурсов системы связи. Моделирование системы связи при использовании сигнала перехода пользовательского оборудования в режим сна продемонстрировало его универсальность относительно типа трафика поступающих данных.
The purpose of this work is to increase the efficiency of the discontinuous reception (DRX) scheme used for user equipment (UE) energy saving in 5th Generation (5G) wireless mobile communication systems of the New Radio (NR) standard starting from the first release (NR Release-15). In the second part of the paper, the energy efficiency of the algorithms proposed in the first part is analyzed by the system level simulations for various traffic models in the most important scenario (Dense Urban Macro) of the 5G wireless mobile communication systems deployment in urban environments. The analysis of the simulation results showed that the proposed methods of the discontinuous reception scheme adaptation to incoming traffic provide a significant gain in energy saving (up to 70%) for all types of data traffic in case of low load of the communication system time-frequency resources. Modeling of the communication system with using the signal for the user equipment transition to sleep mode demonstrates its versatility with respect to the type of incoming data traffic.
Un an de jurisprudence sur les clauses abusives : des plaideurs téméraires, des juges audacieux, des professionnels imprudents (ou calculateurs)
Authors: Pierre Nathalie 
Published: June 2024

Les espèces soumises en 2023 à la cour d’appel de Grenoble en matière de clauses abusives peuvent étonner. D’une part, il faut constater que certains plaideurs, ne répondant manifestement pas à la définition du consommateur ou du non‑professionnel, se lancent tout de même dans une action en justice tendant à faire reconnaître abusive une clause sur le fondement du droit de la consommation. D’autre part, il est à regretter que certains professionnels insèrent encore dans leurs contrats des clauses s’analysant en des clauses noires, préalablement identifiées par le pouvoir réglementaire et irréfragablement présumées abusives. L’apport majeur de la cour est de trancher une question à notre connaissance inédite : celle de la prescriptibilité ou non de l’action en indemnisation des préjudices subis par le consommateur et découlant de l’insertion d’une clause abusive. Fondée sur la nécessité d’assurer au consommateur une protection effective, l’imprescriptibilité d’une telle action est affirmée par la cour d’appel de Grenoble.
La détermination du point de départ du délai quinquennal de prescription de l’article 2224 du Code civil
Authors: Milleville Sébastien 
Published: June 2024

La prescription quinquennale de l’article 2224 du Code civil courant à compter du jour où le titulaire d’un droit « a connu ou aurait dû connaître les faits » lui permettant d’agir, il revient aux juges du fond d’établir, au gré des espèces, ce qu’il faut entendre par cette connaissance effective des faits. La présente contribution se propose donc de présenter quelques traits saillants de la doctrine de la cour d’appel de Grenoble en matière de point de départ du délai de l’article 2224. Si dans certains cas la détermination de la date de la connaissance effective des faits semble aisée, dans d’autres, sous l’apparence de l’accessibilité des informations en cause, cette connaissance semble supposée. C’est alors une ignorance blâmable des faits qui est sanctionnée par la prescription, ce qui peut conduire le créancier à rechercher l’existence de faits justificatifs à son inaction.

РАННЯ ТВОРЧІСТЬ ЛЕВА ҐЕЦА (1915–1919)
Authors: Ґах Ірина 
Published: June 2024

Уперше досліджено становлення та розвиток образотворчості Українських Січових Стрільців у рисунках Лева Ґеца (1896–1971 рр.) періоду Першої світової війни, в яких достовірно передано життя й бойові звершення Українського Легіону 1915–1918 рр., що мали вплив на розвиток національно-культурного руху в першій чверті XX ст. Розглянуто серію графічних робіт художника, створених безпосередньо на полі бою чи під час відпочинку між наступами та представлених у загальному контексті основних напрямів розвитку стрілецької творчості: карикатури, портрету, ілюстрації. Продемонстровано мистецькі досягнення молодого художника в малюнку, набуті в процесі постійних практик в умовах перебігу військових дій. Простежено послідовний розвиток його творчого потенціалу – від швидкого начерку (первісного рисунка) до майстерно викінченого рисунка. Висвітлено ранні мистецькі напрацювання Ґеца та відслідковано якісний поступ фахового володіння графічними засобами (контурною лінією, штрихом, тональними площинами). Констатовано, що провідним жанром у творчості бійця-усусівця Л. Ґеца став баталістичний рисунок. Водночас з’ясовано, що ранні твори художника слугували підготовчим ескізно-начерковим матеріалом для створення мистецьких рукотворних книг-альбомів «Антольоґія стрілецької творчости» 1915–1918 рр. та «Домбє 1918–19 рр.». Здійснено аналіз ранньої стрілецької графіки Л. Ґеца: тематики, композиції, образно-художніх рішень, сюжетних ліній, техніки виконання.Завданням публікації є огляд мистецької спадщини Л. Ґеца та розгляд творчості художника в період 1915–1919 рр. Методологія дослідження спирається на використанні композиційного, стилістичного, структурно-логічного та історичного аналізу; комплексний підхід застосовано до огляду візуальних джерел хронологічного і джерелознавчого методів. Наукова новизна дослідження полягає у введенні маловідомих графічних творів Лева Ґеца 1915–1918 років в українське мистецтвознавство. Вперше пропоновано ранні графічні твори художника як предмет дослідження, комплексного аналізу мистецьких напрацювань якого досі немає.Потреба детального вивчення графіки спадщини визначається необхідністю окреслити цілісну панораму українського мистецтва першої третини ХХ ст. з урахуванням забутих чи невідомих творів художника, без яких неможливо охопити та осмислити тенденції розвитку культурно-мистецької діяльності Українських Січових Стрільців, істотно доповнити загальну картину національного образотворчого мистецтва того часу. Рисунки Лева Ґеца цього періоду протягом половини століття зберігалася в архівах бібліотеки оо. Василіян в Римі і були практично недоступними для дослідження. Тож уся пропонована автором інформація є цінною для кращого розуміння мистецької вартості графічного спадку художника, що має стати вагомим доповненням надбань історичного та батального жанрів в образотворчій культурі першої третини ХХ ст.Метою публікації є представлення ранньої творчості Лева Ґеца 1915–1919 рр. у динаміці розвитку його мистецького таланту, репрезентація малодослідженої серії рисунків періоду Першої світової війни.

Published: June 2024

Research in higher education has consistently focused on determining factors that influence student success and retention in academic programs. Successful students also positively impact the effectiveness of teaching practices used in a course. Previous work shows that a recurring set of assignments where students reflect on past work and set a SMART goal to make a specific improvement promotes a growth mindset and is an activity that students see value in completing. Promoting improvements by students should also make an instructor’s teaching efforts more effective. To understand how instructors and institutions can provide more support for student development and retention, students at four universities completed reflection and planning assignments that involved goal setting based on the SMART goal framework. Student submissions were analyzed to categorize the topic areas where students saw the need to work. Results highlighted the importance of many topics, including time management, self-care, course content, and study methods. Analysis of the data also revealed that facilitating exercises requiring students to set goals and report on their progress later in the term greatly enhanced student engagement and fostered behaviors geared towards establishing a growth mindset.

Abstract
The star formation history (SFH) is a key issue in the evolution of galaxies. In this work, we developed a model based on a Gaussian and gamma function mixture to fit SFHs with varying numbers of components. Our primary objective was to use this model to reveal the shape of SFHs and the corresponding physical driving factors. Specifically, we applied this model to fit SFHs from the TNG100-1 simulation. Our study led to the following findings. (1) Our model fits with TNG star formation histories well, especially for high-mass and red galaxies; (2) a clear relationship exists between the number and shape of fitted components and the mass and color of galaxies, with notable differences observed between central/isolated and satellite galaxies. (3) Our model allows us to extract different episodes of star formation within star formation histories with ease and analyze the duration and timing of each star formation episode. Our findings indicate a strong relationship between the timing of each star formation episode and galaxy mass and color.
The Advective Flux Transport Model: Improving the Far Side with Active Regions Observed by STEREO 304 Å

Published: June 2024

Abstract
Observations of the Sun’s photospheric magnetic field are often confined to the Sun–Earth line. Surface flux transport (SFT) models, such as the Advective Flux Transport (AFT) model, simulate the evolution of the photospheric magnetic field to produce magnetic maps over the entire surface of the Sun. While these models are able to evolve active regions that transit the near side of the Sun, new far-side side flux emergence is typically neglected. We demonstrate a new method for creating improved maps of the magnetic field over the Sun’s entire photosphere using data obtained by the Solar TErrestrial RElations Observatory (STEREO) mission. STEREO He ii 304 Å intensity images are used to infer the time, location, and total unsigned magnetic flux of far-side active regions. We have developed an automatic detection algorithm for finding and ingesting new far-side active region emergence into the AFT model. We conduct a series of simulations to investigate the impact of including active region emergence in AFT, both with and without data assimilation of magnetograms. We find that while He ii 304 Å can be used to improve surface flux models, care must taken to mitigate intensity surges from flaring events. We estimate that during Solar Cycle 24's maximum (2011–2015), 4–6 × 1022 Mx of flux is missing from SFT models that do not include far-side data. We find that while He ii 304 Å data alone can be used to create synchronic maps of photospheric magnetic field that resemble the observations, it is insufficient to produce a complete picture without direct magnetic observations from magnetographs.

Abstract
Radio observations of pulsars offer a potential method to probe the intricate microstructure in the turbulent interstellar medium. Here we report on a high-resolution dynamic spectral analysis of the “swooshing pulsar” B0919+06 observed with the Five-hundred-meter Aperture Spherical radio Telescope over multiple epochs and with the ultrawideband receiver on the Parkes radio telescope. For all observations, the dynamic scintillation spectra, two-dimensional autocovariance functions, and secondary spectra are presented. At 1250 MHz, the decorrelation bandwidth, diffraction timescale, and the drift rate are determined to be Δν

MHz−1, respectively. The frequency dependencies of the scintillation parameters exhibit single power-law spectral behaviors, indicating that the electron density fluctuations in the interstellar medium approximately follow the Kolmogorov spectrum. The secondary spectra exhibit two distinct parabolic arcs with well-determined curvatures of 0.002 and 0.02 s3 for the outer and inner arcs, respectively. The locations of the scattering screens are approximately determined to be 157.3 and 726.0 pc, respectively, from the pulsar for isotropic scattering. The inner scintillation arc is present contemporaneously over a wide frequency range, indicating that the scintillation arc is a broadband phenomenon. The arc curvature scales with observing frequency as a power law with an index of −2.05 ± 0.05, which implies that the scattering screen spans a physical distance from 689.7 to 883.3 pc from the pulsar.
Do We Finally Know all Stellar and Substellar Neighbors within 10 pc of the Sun?
Authors: Scholz Ralf-Dieter , Mints Alexey 
Published: June 2024

Abstract
Our knowledge on the closest solar neighbors gradually improved over a long time with the help of new methods and the recognition of new stellar and substellar species. The latest burst of discoveries since 1997, in which the first author participated, seemingly filled the gap of missing systems within 10 pc from the Sun. However, previous estimates of the population relied on two assumptions: that the sample was complete within 5 pc and that the density was uniform out to 10 pc. The first of these is not true, and the second in question. Otherwise, up to about 90 systems could be still missing within 10 pc. We find no indication for missing brown dwarfs within 10 pc, but strongly increasing deficits from early-M to late-M dwarfs hint at some still hidden late-M dwarf neighbors. They may have already been detected by Gaia but published so far without or with incorrect parallax measurements, because of close companions or their location in the Galactic plane.
Geologic History of the Amundsen Crater Region Near the Lunar South Pole: Basis for Future Exploration

Published: June 2024

Abstract
We provide the first detailed 1:100,000 scale geomorphologic map of the ∼100 km Amundsen crater region, which is of high scientific relevance for future exploration, e.g., NASA’s VIPER mission, the Artemis program, and the Chinese International Lunar Research Station. We investigated the complex geological history of the region before and after the formation of Amundsen crater on the rims of the South Pole–Aitken (SPA) and Amundsen–Ganswindt basins. We present a new Amundsen crater formation age of ∼4.04 Ga, which, in contrast to previously derived ages, is based on non-light-plains terrain. The estimated maximum excavation depth for Amundsen crater is ∼8 km, and elevated concentrations of FeO near the crater suggest that Amundsen may have redistributed SPA-derived materials. Plains materials of various kinds were observed both inside and outside Amundsen crater and are estimated to be up to 350 m thick and ∼3.8 Ga old. A less cratered, tens of meters thick mantling unit indicates a resurfacing event ∼3.7 Ga ago. We highlight five potential exploration sites that satisfy technical constraints (such as shallow slopes, solar illumination, and Earth visibility), provide materials that can be sampled, and are capable of addressing multiple science objectives. Due to its accessibility and traversability, combined with its geologic diversity, proximity of permanently shadowed regions for studying volatile processes, and ability to address multiple science objectives, we confirm and reinforce the Amundsen crater region as a high-priority landing and exploration site.
