Authors: Hu Lei , Xue Junzeng , Wu Huixian 
Published: September 2024

As one of the biggest ports, the aquatic ecology of Shanghai Port has a significant impact on the health of surrounding residents and aquatic animals. Therefore, this study explored the composition and distribution of bacteria, pathogens, and ARGs at Shanghai Ports by high-throughput sequencing. The results showed that the bacterial community was dominated by the Proteobacteria at the phylum level. With the refinement of classification level, the main composition of bacteria in different samples shows significant differences. In contrast, there was no significant difference in the composition and distribution of pathogens among the samples. It indicates that pathogens and ARGs have steady community composition at Shanghai Port. Pseudomonas aeruginosa and Salmonella enterica could be regarded as candidate indicator pathogens. macB, tetA (58), and evgS were the main ARGs, and they showed a close relationship with Mycobacterium tuberculosis, Magnaporthe oryzae, Streptococcus pneumonia, Xanthomonas oryzae, and Vibrio cholerae in different sites and layers. This may lead to the transfer of ARGs between different pathogens, resulting in more threatening pathogens. The results showed that the pathogens and ARGs present posed a risk of transmission and were potentially harmful to residents in the environment. They can spread to any other ports in the world through the transmission of ballast water, posing a threat to humans and local ecology. In order to keep human health, it is necessary to pay more attention to the water environment of ports and increase the monitoring. Furthermore, it is essential to strengthen the supervision of external source pollution input due to the special features of the port.

Objetivo: Descrever a vivência enquanto estudantes de pós-graduação stricto sensu durante a pandemia da Covid-19 e as implicações do ensino remoto para o processo de ensino-aprendizagem do futuro docente/pesquisador. Método: Trata-se de um estudo descritivo, do tipo relato de experiência, desenvolvido a partir da vivência enquanto mestrandas ingressantes na pós-graduação stricto sensu de instituições públicas brasileiras durante o período de pandemia ocasionado pelo novo coronavírus. Para a realização do estudo, utilizou-se diário de campo e observação participante. Resultados: Assim, foi relatado: a realização do processo seletivo integralmente à distância; o adentrar na pós-graduação por meio das tecnologias; um método emergencial para produzir pesquisa científica; elementos facilitadores advindos do ensino remoto; desafios impostos pelas tecnologias associadas à educação; o formato híbrido e o retorno do ensino presencial. Desse modo, a pandemia impulsionou mudanças no ensino, com destaque para a pós-graduação, revelando tanto as oportunidades quanto as dificuldades enfrentadas pelos alunos e instituições durante esse período de adaptação. Considerações Finais: Deve-se considerar os desafios em relação ao ensino remoto forçado emergencialmente, o que demonstrou um certo despreparo quanto às habilidades tecnológicas de docentes e discentes, além da dependência das conexões de internet, conciliação dos estudos com as rotinas domiciliares e transformações nas estratégias de ensino utilizadas, sendo que, todos estes apontamentos podem não contemplar um ensino efetivo, como presencialmente. Entretanto, as tecnologias da informação e comunicação podem ser potentes aliadas no processo de ensino-aprendizagem na pós-graduação, e estas foram substanciais para reduzir os impactos pandêmicos no sistema educativo e possibilitar a continuidade da formação, qualificação profissional e o desenvolvimento de pesquisas científicas.

Authors: Krzyżowska Ewelina 
Published: September 2024

In the era of a knowledge-based economy, effective knowledge management, including knowledge sharing, is one of the determinants of organizational performance. Therefore, the task of companies should be to optimize the process of knowledge sharing, which is achieved by, among other things, a thorough understanding and use of the factors that affect this process. Aim. The purpose of the article was to study the relationship between the level of occupational stress and readiness towards knowledge sharing among IT Sector Employees. Method. A cross-sectional study model was applied. The study included 98 employees from the IT industry. The study used the Perceived Stress at Work Scale (PSaW) by Chirkowska-Smolak and Grobelny and a self-designed survey including: demographic data, work-related variables and questions about knowledge sharing with co-workers. Results. In the surveyed group of IT workers, greater readiness to share knowledge was found among employees who showed lower scores on the PSaW scale. In addition, significant relationships were found between the study variables according to the selected variables, including that among women with low rates of perceived stress at work, older women showed greater willingness to share knowledge compared to younger women. Furthermore, in terms of work-related variables, the results showed that among men declaring high rates of stress, those with shorter seniority were more willing to share knowledge compared to men with longer seniority. Conclusions: The research findings significantly broaden knowledge in the sphere of the factors influencing the effective organization of the knowledge management process, particularly knowledge sharing under stressful work conditions. This knowledge can be useful especially for IT managers.

Berkembang pesatnya teknologi informasi dan komunikasi saat ini jelas sangat memberikan pengaruh terhadap kegiatan manusia terutama dalam melakukan transaksi jual beli melaui media online (internet). Peran internet sebagai media untuk bersosialisasi sangat memudahkan masyarakat untuk melakukan transaksi jual beli online. Hal ini dikarenakan koneksi jaringan yang dilakukan secara cepat dan mudah, serta dapat dijaukau oleh berbagai kalangan. Dampak negatif dalam transaksi jual beli online yang sering terjadi yakni penipuan dalam bertransaksi dan ketidaksesuaian barang dengan spesifikasi. Selain itu, resiko cacat tersembunyi dari barang yang diperjualbelikan juga menjadi modus terbesar dari pelaku usaha online, baik secara sengaja maupun tidak sengaja. Berbagai dampak negatif tersebut membuat penulis tertarik untuk menghimbau mengenai jual beli online yang aman dan syar’i berdasarkan studi terhadap pandangan pelaku bisnis online di kalangan Santri Darul Hikmah Langkap Burneh Bangkalan. Jenis penelitian ini merupakan penelitian lapangan (field research) kualitatif dengan metode wawancara terstruktur dengan penentuan subyek purposive sampling. Analisa data dan pembahasan dilakukan dengan menggunakan teori jual beli dan etika jual beli. Sedangkan pengambilan data yakni informan diambil dari para pelaku bisnis online di kalangan Santri Darul Hikmah Bangkalan. Hasil dari penelitian ini, pertama transaksi jual beli online melalui transaksi COD (Cash On Delivery) aman dilakukan, karena penjual dan pembeli terlibat secara langsung. Sedangkan untuk meminimalisir resiko yang sering terjadi dalam jual beli online, pelaku bisnis online dapat menggunakan rekening bersama (rekber) sebagai pihak ketiga dalam transaksi online. Rekber dapat menjadi salah satu solusi untuk menjamin keamanan dan kenyamanan antara penjual dan pembeli, karena dana baru akan disampaikan ke penjual ketika barang sudah sampai ke pembeli. Jual beli online dapat dikatakan Syar’i jika sudah memenuhi rukun dan syarat jual beli, sesuai dengan syarat yang terdapat dalam akad bay‘ maws{uf fi dhimmah, memenuhui etika jual beli, serta asas-asas perjanjian dalam hukum Islam salah satunya adalah asas amanah dan atas dasar tarad{in (saling rid{a).

Reduced contextual uncertainty facilitates learning what to attend to and what to ignore

Published: September 2024

AbstractVariability in the search environment has been shown to affect the capture of attention by salient distractors, as attentional capture is reduced when context variability is low. However, it remains unclear whether this reduction in capture is caused by contextual learning or other mechanisms, grounded in generic context-structure learning. We set out to test this by training participants (n = 200) over two sessions in a visual search task, conducted online, where they gained experience with a small subset of search displays, which significantly reduced capture of attention by colour singletons. In a third session, we then tested participants on a mix of familiar and novel search displays and examined whether this reduction in capture was specific to familiar displays, indicative of contextual cueing effects, or would generalise to novel displays. We found no capture by the singleton in either the familiar or novel condition. Instead, our findings suggested that reduced statistical volatility reduced capture by allowing the development of generic predictions about task-relevant locations and features of the display. These findings add to the current debate about the determinants of capture by salient distractors by showing that capture is also affected by generic task regularities and by the volatility of the learning environment.
Behavioural stochastic resonance across the lifespan
Authors: Di Ponzio Michele , Battaglini Luca , Bertamini Marco , Contemori Giulio 
Published: September 2024

AbstractStochastic resonance (SR) is the phenomenon wherein the introduction of a suitable level of noise enhances the detection of subthreshold signals in non linear systems. It manifests across various physical and biological systems, including the human brain. Psychophysical experiments have confirmed the behavioural impact of stochastic resonance on auditory, somatic, and visual perception. Aging renders the brain more susceptible to noise, possibly causing differences in the SR phenomenon between young and elderly individuals. This study investigates the impact of noise on motion detection accuracy throughout the lifespan, with 214 participants ranging in age from 18 to 82. Our objective was to determine the optimal noise level to induce an SR-like response in both young and old populations. Consistent with existing literature, our findings reveal a diminishing advantage with age, indicating that the efficacy of noise addition progressively diminishes. Additionally, as individuals age, peak performance is achieved with lower levels of noise. This study provides the first insight into how SR changes across the lifespan of healthy adults and establishes a foundation for understanding the pathological alterations in perceptual processes associated with aging.

Abstract
The Sun moves through the interstellar medium (ISM) at a velocity of ∼19 pc Myr−1, making the conditions outside the solar system vary with time over millions of years. Today’s solar system is protected from interstellar particles by the heliosphere, the bubble formed by the solar wind as the Sun moves through the ISM, which engulfs the planets. There is geological evidence from 60Fe that Earth was in direct contact with the ISM 2–3 and 5–7 million years ago (MYA). Recent work argues that the Sun encountered a massive cold cloud 2 MYA as part of the Local Ribbon of Cold Clouds that shrunk the heliosphere and exposed Earth to the ISM. Here, we consider the effects of the passage of the Sun through the edge of the Local Bubble occurring at

MYA assuming that the Sun encountered a cloud with a density of 900 cm−3. If we consider additional turbulent motion within the cloud due to shocks, the density encountered can be as low as 283 cm−3. Clouds of this density cover a small but nonzero (≲4.6%) fraction of the surface of the Local Bubble, making an encounter plausible. Using a state-of-the art magnetohydrodynamic model, we show that the heliosphere shrank to a scale smaller than Earth’s orbit, thereby exposing Earth to cold dense ISM, consistent with 60Fe evidence. The timing of the event matches perturbations observed in the paleoclimate record recovered from deep-sea sediments. The passage through the Local Bubble’s surface and contraction of the heliosphere therefore may have impacted the climate and biosphere significantly, suggesting a new driver of major events in Earth’s history.

Abstract
The X-ray thermal isolated neutron star (XTINS) RX J0806.4–4123 shows interesting multiwavelength properties that seemingly deviate from those of similar neutron stars. An accurate determination of the spin frequency change over time can assist in interpreting RX J0806.4–4123's properties in comparison to those of other XTINSs and the wider pulsar population. From 2019 to 2023 we carried out a tailored X-ray timing campaign of RX J0806.4–4123 with the NICER instrument. We used statistical properties of the Fourier coefficients and the Z

Abstract
Solar flare prediction studies have been recently conducted with the use of Space-Weather MDI (Michelson Doppler Imager on board Solar and Heliospheric Observatory) Active Region Patches (SMARPs) and Space-Weather HMI (Helioseismic and Magnetic Imager on board Solar Dynamics Observatory) Active Region Patches (SHARPs), which are two currently available data products containing magnetic field characteristics of solar active regions (ARs). The present work is an effort to combine them into one data product, and perform some initial statistical analyses in order to further expand their application in space-weather forecasting. The combined data are derived by filtering, rescaling, and merging the SMARP and SHARP parameters, which can then be spatially reduced to create uniform multivariate time series. The resulting combined MDI–HMI data set currently spans the period between 1996 April 4 and 2022 December 13, and may be extended to a more recent date. This provides an opportunity to correlate and compare it with other space-weather time series, such as the daily solar flare index or the statistical properties of the soft X-ray flux measured by the Geostationary Operational Environmental Satellites. Time-lagged cross correlation indicates that a relationship may exist, where some magnetic field properties of ARs lead the flare index in time. Applying the rolling-window technique makes it possible to see how this leader–follower dynamic varies with time. Preliminary results indicate that areas of high correlation generally correspond to increased flare activity during the peak solar cycle.

Abstract
We test whether Lyα emitters (LAEs) and Lyman-break galaxies (LBGs) can be good tracers of high-z large-scale structures, using the Horizon Run 5 cosmological hydrodynamical simulation. We identify LAEs using the Lyα emission line luminosity and its equivalent width, and LBGs using the broadband magnitudes at z ∼ 2.4, 3.1, and 4.5. We first compare the spatial distributions of LAEs, LBGs, all galaxies, and dark matter around the filamentary structures defined by dark matter. The comparison shows that both LAEs and LBGs are more concentrated toward the dark matter filaments than dark matter. We also find an empirical fitting formula for the vertical density profile of filaments as a binomial power-law relation of the distance to the filaments. We then compare the spatial distributions of the samples around the filaments defined by themselves. LAEs and LBGs are again more concentrated toward their filaments than dark matter. We also find the overall consistency between filamentary structures defined by LAEs, LBGs, and dark matter, with the median spatial offsets that are smaller than the mean separation of the sample. These results support the idea that the LAEs and LBGs could be good tracers of large-scale structures of dark matter at high redshifts.
