IntroductionThis study examines the relationships between secure base leadership, organizational identification, and resilience among military cadets, utilizing the Job Demands-Resources (JD-R) model as a theoretical framework. Specifically, it explores the mediating role of work engagement in these associations within the context of military training.MethodsA cross-sectional study was conducted with 363 cadets from the General Military Academy of the Army in Zaragoza, Spain. The sample comprised second-year cadets (n = 170; 46.8%) and third-year cadets (n = 193; 53.2%), with a gender distribution of 84% male and 16% female. Participants evaluated their section chief captains using the Leader as Security Provider Scale and completed validated questionnaires measuring work engagement, organizational identification, and resilience. Data were analyzed using partial least squares structural equation modeling (PLS-SEM) to test the hypothesized relationships and mediation effects.ResultsThe findings revealed that secure base leadership is positively associated with work engagement among cadets. Work engagement significantly mediated the relationships between secure base leadership and both organizational identification and resilience. The structural model explained a substantial proportion of variance in the outcome variables, supporting the applicability of the JD-R model in this context.DiscussionThese results underscore the importance of secure base leadership in promoting work engagement, which in turn enhances organizational identification and resilience among military cadets. The study highlights the role of leaders as secure bases in fostering personal and organizational well-being. Implications suggest that incorporating secure base leadership principles in military training programs could contribute to the professional development and overall well-being of military personnel.

BackgroundPerceived stress is recognized as a significant risk factor for depressive symptoms, while psychological resilience and wellbeing are considered crucial protective factors. However, the intricate relationships among these variables in undergraduate nursing interns remain largely unexplored. This study aims to investigate the mediating role of psychological resilience in the relationship between perceived stress and depressive symptoms, as well as the moderating influence of wellbeing on this mediation.MethodsFrom March 1 to 31, 2024, a cluster sampling survey was conducted to examine senior nursing undergraduates from a medical college in Anhui Province who were engaged in clinical practice at various hospitals. The surveyed hospitals were all Grade III, and Class A teaching institutions situated in Anhui, Jiangsu, Zhejiang, Shanghai, and other provinces. According to the Lewinsohn behavioral theory of depression, the study measured perceived stress, depressive symptoms, wellbeing, and psychological resilience using the Chinese Perceived Stress Scale (CPSS), Patient Health Questionnaire 9 (PHQ-9), Oxford Happiness Questionnaire (OHQ), and the Chinese version of the 10-item Connor-Davidson Resilience Scale (CD-RISC-10). The PROCESS v4.0 macro was utilized to evaluate the mediating role of psychological resilience and the moderating role of wellbeing.ResultsA total of 299 valid samples were included. Perceived stress, depressive symptoms, psychological resilience, and wellbeing were significantly correlated. Psychological resilience partially mediated the relationship between perceived stress and depressive symptoms [indirect effect = 0.111, 95% Boot CI (0.065, 0.162)]. Wellbeing also moderated the relationship between psychological resilience and depressive symptoms [B = 0.007, 95% Boot CI (0.003, 0.011)].ConclusionThe mental health of undergraduate nursing interns warrants attention. To reduce perceived stress and depressive symptoms, interventions should focus on enhancing psychological resilience and wellbeing among these interns.

BackgroundCognitive impairment is a major public health concern in aging societies. This study aimed to investigate the prevalence of cognitive impairment and its associated factors among Chinese adults aged 60 years and older using data from the 2018 China Health and Retirement Longitudinal Study (CHARLS).MethodsUtilizing data from the 2018 wave of CHARLS, we assessed participants’ cognitive status using the Mini-Mental State Examination (MMSE), and the influencing factors related to cognitive impairment were analyzed by using the chi-square test and multifactor logistic regression. The prevalence of cognitive impairment was stratified by gender, education level, residence, marital status, daytime napping, and nighttime sleep duration, and the trend of cognitive impairment prevalence with age was observed.Results9,804 participants were finally included in the study and the overall prevalence of cognitive impairment was 44.04% (95%CI, 43.02–45.06%). The prevalence was significantly higher in females (50.8%) than males (37.1%), and increased with age, from 41.5% in those aged 60–64 years to 57.7% in those aged ≥75 years. Lower educational level, rural residence, and being divorced/ widowed/unmarried were associated with a higher prevalence of cognitive impairment (all p &lt; 0.001). Multifactor logistic regression indicated that older age (OR = 1.51, 95%CI, 1.33–1.73 for ≥75 vs. 60–64 years), female gender (OR = 1.54, 95%CI, 1.35–1.77), higher education (OR = 0.46, 95%CI, 0.42–0.51 for primary school and below vs. illiteracy), rural areas (OR = 2.35, 95%CI, 2.07–2.65 for village vs. the center of city/town), divorced/ widowed/unmarried status (OR = 1.40, 95%CI, 1.25–1.57) and participation in physical activity (OR = 0.80, 95%CI, 0.73–0.87) were significantly associated with cognitive impairment.ConclusionCognitive impairment is highly prevalent among older adults in China with substantial demographic disparities. Targeted interventions and public health strategies are needed to promote cognitive health in this rapidly aging population.

Published: December 2024

Two new species of the genus Cherax are described and illustrated. Cherax rayko n. sp., endemic to the Bian River drainage basin in the Muting District, in the northern part of the Merauke Regency, South Papua, Indonesia, is described, figured, and compared with its closest relatives, Cherax alyciae, Lukhaup, Eprilurahman & von Rintelen, 2018, and Cherax peknyi Lukhaup & Herbert, 2008. The new species may be easily distinguished from both by the shape of the rostrum, the shape of the chelae, the shape of the scaphocerite, and the coloration. Cherax phing n. sp., endemic to the Kali Ombak River drainage basin in the western part of the Kepala Burung (Vogelkop) Peninsula, Southwest Papua, Indonesia, is described, figured, and compared with its closest relatives, Cherax pulcher Lukhaup, 2015a, Cherax boesemani Lukhaup & Pekny, 2008, Cherax wagenknechtae Lukhaup and Eprilurahman, 2022, and Cherax gherardii Patoka, Bláha & Kouba, 2015. The new species may be easily distinguished from the latter species by the shape of the chelae, rostrum, and body and by the coloration. A molecular phylogeny based on a mitochondrial gene fragment, 16S, supports the morphology-based description of the two new species, which can also be clearly distinguished by sequence differences.
First Description of the Role of the Relationship Between Serum Amyloid P Components and Nuclear Factors/Pro-Cytokines During Critical Periods of Toxoplasmic Encephalitis
Authors: Dincel Gungor Cagdas , Atmaca Hasan Tarik , El-Ashram Saeed 
Published: December 2024

Background/Objectives: Toxoplasma gondii (T. gondii), an obligate food-borne intracellular parasite, causes severe neuropathology by establishing a persistent infection in the host brain. We have previously shown that T. gondii infection induces severe neuropathology in the brain manifested by increased nitric oxide production, oxidative stress, glial activation/BBB damage, increased pro-inflammatory cytokine glia maturation factor-beta and induced apoptosis. Methods: The aim of this experimental study was to investigate the serum amyloid P (SAP) components, nuclear factor kappa B (NF-κB), interleukin-1 beta (IL-1β), caspase 1 (Casp 1), tumor necrosis factor-alpha (TNF-α) and complement 3 (C3) gene expressions on the 10th, 20th and 30th days after infection with T. gondii in the neuroimmunopathogenesis of toxoplasmic encephalitis (TE) in mouse brains by real-time quantitative polymerase chain reaction. The study also aimed to determine whether there was a correlation between the markers included in the study on these critical days, which had not previously been investigated. The mRNA expression levels of SAP components, NF-κB, IL-1β, Casp 1, TNF-α and C3 were examined. Results: The most notable outcome of this investigation was the observation that SAP components exhibited a 13.9-fold increase on day 10 post-infection, followed by a rapid decline in the subsequent periods. In addition, IL-1β expression increased 20-fold, while SAP components decreased 13-fold on day 20 after infection. Additionally, the TNF-α, Casp 1 and NF-κB expression levels were consistently elevated to above normal levels at each time point. Conclusions: This study identified SAP components, NF-κB, IL-1β, Casp 1 and TNF-α expressions as playing critical roles in TE neuroimmunopathogenesis. Furthermore, to the best of our knowledge, this is the first study to investigate SAP components during the transition from acute systemic infection to early/medium chronic and chronic infection and to explore the relationship between SAP components and other nuclear factors/pro-cytokines.
Advances in Stellar and Galactic Evolution with the Population of Planetary Nebula Progenitors from the APOGEE DR17 Survey

Published: December 2024

Planetary nebulae (PNe) are the ejected gas and dust shells of evolved low- and intermediate-mass stars (LIMSs). We present an abundance comparison between PNe and their progenitors to reveal their similarities and differences since such a comparison has rarely, and not recently, been performed in the Milky Way. The dynamical expulsion of the outer envelope of an evolved LIMS produces the PN. We expected similarities in most α-element distributions across the stellar and nebular populations, given that these elements are only marginally produced and destroyed during the LIMS evolution. Differences found in the Fe and S abundances allow us to determine their depletion due to grain condensation in the post-AGB phases. Differences in N and C between PNe and their progenitors set new limits to the low- and intermediate-mass star contributions to these elements. Finally, radial metallicity gradients from evolved LIMS and PNe and Gaia-calibrated distances constrain Galactic evolution in the framework of the current chemical evolutionary models. We found the following: (1) Gas-phase iron is significantly depleted in PNe compared to their progenitor stars, with an average depletion factor of <D[Fe/H]> = 1.74 ± 0.49. (2) Sulfur is also depleted in PNe, though to a much lesser extent than iron. (3) The median enrichment levels for carbon and nitrogen relative to the median stellar population of the same metallicity are approximately [C/H] ∼ +0.3 and [N/H] ∼ +0.4, respectively. PNe with progenitors that experienced hot-bottom burning (HBB) exhibit extreme nitrogen enrichment. (4) With the data available to date, the radial metallicity gradient derived from evolved LIMSs and PNe are compatible within the uncertainties.
“Laura em aimará”: referências italianas na dinâmica cultural andina proposta por Gamaliel Churata
Authors: Hernando Marsal Meritxell 
Published: December 2024

O escritor peruano Gamaliel Churata (1897-1969) incorpora na sua obra personagens e referências italianas que devem ser compreendidas a partir da dinâmica cultural que o autor propõe a partir das culturas andinas, que configuram o eixo discursivo da obra do ponto de vista temático, filosófico e linguístico. Em um primeiro momento, vai ser descrita a militância vanguardista de Churata nos anos vinte na revista Boletín Titikaka (1926-1930) e o conceito de indoamericanismo desenvolvido por ele, pois implica uma definição da identidade americana fundada no reconhecimento contemporâneo das culturas originárias (com forte crítica ao colonialismo interno das repúblicas americanas) mas aberta à diferença. A seguir, o sistema estético dos tecidos andinos oferecerá modelos de relação, como o tinku e as k’isas, que implicam tensão e metamorfose. Com base nesse paradigma relacional, poderá ser entendido o lugar que a obra de Churata oferece a Dante e Petrarca, onde os versos, personagens e palavras em italiano entram em um diálogo ativo com a concepção andina da morte como semente e continuidade e, em certa forma, se aimarizam.
BELO, ALÉM DA BELEZA, E A RECEPÇÃO DO FEMININO GRECO-ROMANO NO CANCIONEIRO PARAIBANO DE CHICO CÉSAR E ZÉ RAMALHO

Published: December 2024

No que se refere ao estudo dos mitos, um aspecto que julgamos ser fundamental é o seu alcance universal, como aquele em que se vê o seu direcionamento às mais diversas formas de conhecimentos e culturas. Especialmente, nosso interesse é ainda maior quando essa presença se faz notória na cultura brasileira. Como sabemos, as narrativas míticas são reinterpretadas por diversos autores e artistas, conduzindo criações artísticas que expressam ideias e emoções de maneira poética e simbólica. Além disso, a mitologia oferece uma rica fonte de histórias adaptáveis, permitindo reflexões contemporâneas sobre valores históricos e representativos. E, diante dessa percepção interpretativa e intertextual, artistas como Zé Ramalho, Chico César e Chico Buarque, entre outros, fazem uso dessas histórias mitológicas em suas composições. Com isso, este artigo visa explorar a presença da mitologia nas canções populares, particularmente, nas que expressam uma ênfase nas figuras femininas míticas, como fundamentação de análise da recepção do feminino em sua abordagem, não só na Antiguidade, como nos tempos atuais, de modo que possamos contribuir para uma compreensão do feminino no mundo clássico sob uma perspectiva atemporal. Para tanto, dialogaremos com autores como Martha Robles (2019), Luciana Ferreira Mendonça (s/d), Marta Mega de Andrade (2003), Airan Borges dos Santos (2020), Verônica de Fátima Gomes Moura (2011), Pierre Bourdieu (1989) e Marcus Reis Pinheiro (2010). Com esse propósito, realizaremos a exposição de três tópicos: 1. Além da beleza, a essência do Belo e sua dimensão: contextualização sobre o feminino e o belo na Antiguidade; 2. Entre objetificações e sentidos genuínos: a recepção da mulher da Antiguidade greco-romana no cancioneiro popular de Zé Ramalho e Chico César; 3. Análise da representação feminina greco-romana em “Mulher nova, bonita e carinhosa”, de Zé Ramalho. Ao longo dos tópicos propostos, abordaremos como cada um se correlaciona entre si, abarcando os métodos de estudo e análise para alcançar tal objetivo de pesquisa
Development of an automatic frequency tracking electret vibration energy harvester
Authors: Tsuboi Kirara , Nakazawa Kenta , Toshiyoshi Hiroshi , Hashiguchi Gen 
Published: December 2024

Abstract
This paper presents the development of a vibration energy harvester where the resonant frequency of the energy harvester automatically tracks the vibration frequency of environments. This device consists of two movable structures: a cantilever structure that displaces in the out-of-plane direction (z-direction) and a folded beam structure that displaces in both the out-of-plane and in-plane directions (x-direction). Between the two movable structures, triangular comb-electrodes are designed, and these form a coupled vibrating system connected by electrostatic springs. By applying a charging voltage of a half-wave voltage doubler rectifier circuit between the comb-electrodes of the harvester via a 200 MΩ feedback resister, the resonant frequency can be followed to the environmental vibration frequency automatically. Although the half-width of the developed harvester was only 4 Hz, we successfully achieved tracking over a range of 11 Hz, allowing us to generate a high charging voltage across a wide frequency range.

islands which roughen the surface and affect the following regrowth. To achieve smooth and high-quality regrown AlN films, various surface cleaning technologies for HTA-AlN templates were investigated. Conventional alkaline or acidic chemical cleaning has a poor effect on improving the surface of HTA-AlN templates and many V-pits appeared on the regrown-AlN surface. On the other hand, thermal cleaning could remove Al

Furthermore, the regrown-AlN layer after thermal cleaning has less than 0.2 nm roughness without any surface defects and maintains high crystallinity as the HTA-AlN templates. This study provides a convenient and effective method for cleaning the HTA-AlN templates, which can be used in the industrialization of AlGaN-based devices.

Soil Infestation with Western Corn Rootworm Eggs and Larval Emergence Timing in the Right-Bank Forest-Steppe of Ukraine
Authors: Saliienko V. , Remeniuk S. 
Published: December 2024

Goal. To determine the soil infestation with western corn rootworm (WCR) eggs depending on the duration of corn cultivation in one area, as well as to study the timing of larval development stages taking into account the sum of effective temperatures (SET) in the Right-Bank Forest-Steppe of Ukraine.
Methods. The study was conducted in 2021—2023 in the fields of Khmilnyk district, Vinnytsia region. The methodology included soil sampling to analyze the number of eggs in samples measuring 10 × 10 cm and 15 cm deep. The samples were examined by washing and flotation using magnesium sulfate solutions, after which the number of eggs was determined under a microscope. Morphological assessment of the chorion surface was used to identify eggs. Additionally, phenological observations of the larval developmental stages based on the accumulation of SET were performed.
Results. The number of eggs of the WCR varied from 11.3 to 47.6 per sample (1130—4760 pcs./m²). The lowest values were observed in the fields with two years of corn cultivation, and the maximum values were recorded in the fields with four years of crop cultivation. The dependence of the number of eggs on weather conditions was also significant: the driest year, 2022, was characterized by a reduced level of soil infestation compared to other years. The average time of hatching of the first instar larvae was recorded in the second decade of June at 150—160°C, the second instar — within 6—9 days after the emergence of the first instar larvae, and the third instar — in the third decade of June. Pupation occurred in late June — early July.
Conclusions. The data obtained indicate that the intensity of soil infestation depends on the duration of corn cultivation in one field and weather conditions. The use of the SET method proved to be effective in predicting the stages of pest development. Results can be used to improve the monitoring system and optimize the timing of protective measures.
