Despite the multitude of research on charisma of leaders, researchers have failed to reach a consensus on its nature. The main debate is whether charisma resides innately.within a leader or it is developed from specific relationships. This paper elucidates this issue using empirical studies from China. Combining qualitative investigations and exploratory.factor analy.is, we find that leader charisma consists of three dimensions： love towards followers, talents and wisdom of leadership, and public virtue. The three-factor structure of charisma suggests that a leader＇s charisma on the surface originates from leader＇s personality.and behavior but it can actually.only.be fully.understood by.integrating the relationship-centered view of charisma.

The rapid development of the internet and digital media has provided convenience while also posing a potential risk of steganography.abuse. Identify.ng steganographer is essential in tracing secret information origins and preventing illicit covert communication online. Accurately.discerning a steganographer from many.normal users is challenging due to various factors, such as the complexity.in obtaining the steganography.algorithm, extracting highly.separability.features, and modeling the cover data. After extensive exploration, several methods have been proposed for steganographer identification. This paper presents a survey.of existing studies. Firstly. we provide a concise introduction to the research background and outline the issue of steganographer identification. Secondly. we present fundamental concepts and techniques that establish a general framework for identify.ng steganographers. Within this framework, state-of-the-art methods are summarized from five key.aspects: data acquisition, feature extraction, feature optimization, identification paradigm, and performance evaluation. Furthermore, theoretical and experimental analy.es examine the advantages and limitations of these existing methods. Finally. the survey.highlights outstanding issues in image steganographer identification that deserve further research. © 2024 The Authors. Published by.Tech Science Press.

We present resolved Giant Metrewave Radio Telescope H I observations of the high gas-phase metallicity.dwarf galaxy.WISEA J230615.06+143927.9(z = 0.005)(hereafter J2306) and investigate whether it could be a Tidal Dwarf Galaxy.TDG) candidate. TDGs are observed to have higher metallicities than normal dwarfs. J2306 has an unusual combination of a blue g-r color of 0.23 mag, irregular optical morphology.and high-metallicity.12 +log(O/H) = 8.68 ± 0.14), making it an interesting galaxy.to study.in more detail. We find J2306 to be an H I rich galaxy.with a large extended, unperturbed rotating H I disk. Using our H I data we estimated its dy.amical mass and found the galaxy.to be dark matter(DM) dominated within its H I radius. The quantity.of DM, inferred from its dy.amical mass, appears to rule out J2306 as an evolved TDG. A wide area environment search reveals J2306 to be isolated from any.larger galaxies which could have been the source of its high gas metallicity. Additionally. the H I morphology.and kinematics of the galaxy.show no indication of a recent merger to explain the *** detailed optical spectroscopic observations of J2306 might provide an answer to how a seemingly.ordinary.irregular dwarf galaxy.achieved such a high level of metal enrichment.

We examined the global biogeography.of the Scy.odes thoracica group of spitting spiders based on 23 y.ars of sampling at the species level(61 species in the thoracica group and 84 species of Scy.odes)using DNA data from six *** results indicated that the thoracica group initially.dispersed from Southeast Asia to East Africa between 46.5 and 33.0 million y.ars ago,and dispersal events intensified between Southeast/South Asia and East/South Africa from the early.to late *** timing of these events indicates that Asian-African faunal exchange of the thoracica group was driven by.the Indian monsoon,and the pattern of dispersal suggests that colonialization took root when the Indian monsoon shifted from a North-South direction to an East-West direction from the middle Eocene.
