The Right to Withdraw after Publication of Literary Works: Comparative Study of International Instruments and Some Legal Systems Adopting the Right
No full textIn some civil law countries, creators of literary works are granted a special moral right known as the right to withdraw after publication. By virtue of this right, if the creator's opinions and beliefs change drastically after publication, the author has the right to prevent further publication of the work and stopping its circulation in the market. Also, in some legal systems, this right can be exercised for economic reasons in case of non-exploitation of the work by the publisher.
Since the underlying principle of this right rests on the theory of personality, advocates of the right of withdrawal consider it as a suitable tool to preserve the creator's personality. In contrast, utility-based legal systems refuse to accept it because of its huge costs on publishers. This right is not explicitly recognized in the Iranian legal system. However, given that foundation of literary rights in Iran is mainly based on the preservation of creator's personality, and the right to withdraw is essentially a companion to the right to create and to disclose, this article defends the insertion of this right in Iranian Legal syste
Identifying Specific Human Resource Management Practices for Aging Workforce in Public Organizations
No full textIntroduction: The main capital of any organization is its human resources (HR). Organizations invest substantial costs in attracting, retaining, and training individuals. Therefore, it is essential to identify and implement appropriate practices to preserve and enhance HR. Aging of employees is an inevitable phenomenon that poses challenges to all organizations, irrespective of specific geographical locations, because the employees will get old and leave the organization. This research aims to identify HR management practices for aging employees in public organizations in Jahrom City, Fars Province, Iran, in the year 2022.
Methods: This study utilizes meta-synthesis and Delphi methods to extract and identify management practices for aging HR. In the meta-synthesis section, the library method was used and community under study in the Delphi section included 28 academic (university professors with doctorate degrees in HR or organizational behavior) and organizational (senior managers and HR managers of public organizations in Jahrom) experts. The research tool used in the Delphi section was a questionnaire conducted in 3 rounds.
Results: Through the study of the sources using meta-synthesis method, a total of 79 organizational practices were identified, categorized into 11 main dimensions. After three rounds, a consensus was reached on 60 practices, organized into 9 main dimensions, and the Delphi rounds were concluded. In the final round, no new practices were suggested or removed. Due to the minimal differences in the Kendall coefficient among the different rounds, the Delphi rounds were concluded.
Conclusion: It is necessary to plan and implement all these practices in parallel and simultaneously. However, as the most crucial management measure is planning, there is a need for planning, coordination, and harmonization at the legislative, administrative, and recruitment levels. Implementing the proposed practices through organizational experts, HR managers, and the active participation of aging employees in implementing practical practices will lead to better execution.

Poisson's Ratio and Young's Modulus of Lipid Bilayers in Different Phases
No full textA general computational method is introduced to estimate the Poisson’s ratio for membranes with small thickness. In this method, the Poisson’s ratio is calculated by utilizing a rescaling of inter-particle distances in one lateral direction under periodic boundary conditions. As an example for the coarse grained lipid model introduced by Lenz and Schmid, we calculate the Poisson’s ratio in the gel, fluid, and interdigitated phases. Having the Poisson’s ratio, enable us to obtain the Young’s modulus for the membranes in different phases. The approach may be applied to other membranes such as graphene and tethered membranes in order to predict the temperature dependence of its Poisson’s ratio and Young’s modulus.BN/BionanoscienceApplied Science

Personality element is one of the most important elements in the fiction literature, through which the author displays his thoughts and emotions. The characters carry the main burden of the story and their narrative narrates with their actions and conversations. Youssef Zeydan (1958-?) Is one of the contemporary Egyptian writers and journalists, and so far many works have been published. Al-Nabti\u27s novel is one of his works, which is very different in the way of writing. This novel illustrates the events in the Arabian lands at the beginning of the introduction of Islam into the land of Egypt.The present research has tried to investigate a variety of personality and personality styles in this novel using descriptive-analytical method. The results show that there are 100 characters in the novel, most of which are just their name in the novel. And 18 main and minor characters are involved in the novels. In terms of characterization methods, we also see the author\u27s work in different ways, including direct and indirect. The results indicate that he has used more indirect methods. And along with traditional characterization, it has used other elements such as color and look and feel for characterization.

Under physiological pH 7.4, dicalcium phosphates can gradually interact with calcium carbonate to form hydroxyapatite. Therefore, we hypothesized that aragonite (Arg) could react with dental calculus, facilitating its removal. To assess the reactivity of Arg with dental calculus, we examined the changes in surface morphology, composition, and topography of Arg and dental calculus upon exposure to each other in an aqueous environment. The impact of Arg on the removal of dental calculus was assessed by brushing polished sections of dental calculus, enamel, and dentin with slurries of Arg and measuring the depth of abrasion using a stylus profilometer. Our results demonstrate that Arg can react with dental calculus in aqueous environment. This reaction increases calculus surface roughness which in turn facilitate dental calculus removal by brushing. Aragonite could be a promising abrasive for toothpaste design for management of dental calculus
Supplementary information files for "The effect of cysteine oxidation on conformational changes of SARS-CoV-2 spike protein using atomistic simulations"
No full textSupplementary information files for article "The effect of cysteine oxidation on conformational changes of SARS-CoV-2 spike protein using atomistic simulations"The SARS-CoV-2 Spike (S) protein plays a central role in viral entry into host cells, making it a key target for therapeutic interventions. Oxidative stress, often triggered during viral infections, can cause oxidation of cysteine in this protein. Here we investigate the impact of cysteine oxidation, specifically the formation of cysteic acid, on the conformational dynamics of the SARS-CoV-2 S protein using atomistic simulations. In particular, we examine how cysteine oxidation influences the transitions of the S protein’s receptor-binding domain (RBD) between “down” (inaccessible) and “up” (accessible) states, which are critical for host cell receptor engagement. Using solvent-accessible surface area (SASA) analysis, we identify key cysteine residues susceptible to oxidation. The results of targeted molecular dynamics (TMD) and umbrella sampling (US) simulations reveal that oxidation reduces the energy barrier for RBD transitions by approximately 30 kJ mol−1, facilitating conformational changes and potentially enhancing viral infectivity. Furthermore, we analyze the interactions between oxidized cysteine residues and glycans, as well as alterations in hydrogen bonds and salt bridges. Our results show that oxidation disrupts normal RBD dynamics, influencing the energy landscape of conformational transitions. Our work provides novel insights into the role of cysteine oxidation in modulating the structural dynamics of the SARS-CoV-2 S protein, highlighting potential targets for antiviral strategies aimed at reducing oxidative stress or modifying post-translational changes. These findings contribute to a deeper understanding of viral infectivity and pathogenesis under oxidative conditions.©The Author(s), CC BY-NC-ND 4.0</p

Locus Coeruleus Activation Patterns Differentially Modulate Odor Discrimination Learning and Odor Valence in Rats
No full textThe locus coeruleus (LC) produces phasic and tonic firing patterns that are theorized to have distinct functional consequences. However, how different firing modes affect learning and valence encoding of sensory information are unknown. Here, we show bilateral optogenetic activation of rat LC neurons using 10-Hz phasic trains of either 300 ms or 10 s accelerated acquisition of a similar odor discrimination. Similar odor discrimination learning was impaired by noradrenergic blockade in the piriform cortex (PC). However, 10-Hz phasic light-mediated learning facilitation was prevented by a dopaminergic antagonist in the PC, or by ventral tegmental area (VTA) silencing with lidocaine, suggesting a LC–VTA–PC dopamine circuitry involvement. Ten-hertz tonic stimulation did not alter odor discrimination acquisition, and was ineffective in activating VTA DA neurons. For valence encoding, tonic stimulation at 25 Hz induced conditioned odor aversion, whereas 10-Hz phasic stimulations produced an odor preference. Both conditionings were prevented by noradrenergic blockade in the basolateral amygdala (BLA). Cholera Toxin B retro-labeling showed larger engagement of nucleus accumbens-projecting neurons in the BLA with 10-Hz phasic activation, and larger engagement of central amygdala projecting cells with 25-Hz tonic light. These outcomes argue that the LC activation patterns differentially influence both target networks and behavior.Memorial University Open Access Author's Fun
Uncivil behaviors in nursing education from the perspectives of nursing instructors and students: A cross-sectional study
No full textOne of the serious concerns in nursing education is uncivil behaviors (UBs). These behaviors negatively affect both teaching and learning and result in instructor-student conflicts. Nonetheless, the data about these behaviors is minimal hence the need for a study on them. The study aimed to evaluate UBs in nursing education from the perspectives of nursing instructors and students. This cross-sectional descriptive-analytical study was conducted in 2019 with 52 nursing instructors and 240 nursing students from Kerman, Bam, and Jiroft Universities of Medical Sciences, Iran. Data was collected using the Instructors’ Uncivil Behaviors Scale and the Students’ Uncivil Behaviors Scale and analyzed using the SPSS software (v. 22.0), independent t-test, ANOVA, and Pearson correlation coefficient. Both nursing instructors and students perceived UBs at a moderate level. UBs in the learning climate dimension was the most prevalent and were experienced among both students and instructors. Due to the commonness of UBs, nursing education and healthcare authorities need to employ strategies to minimize these behaviors and reduce their effects on nursing instructors, students, and clients. © 2022 The Author(s
