Should the current radiation protection paradigm and its recommendations be modified to make them more fit to protect the public in future nuclear emergencies?

Abstract The present radiation protection paradigm and its associated recommendations as developed by bodies such as the ICRP have performed very well over past decades both for those occupationally exposed to radiation and for the public in planned exposures. There is, however, growing evidence that the role played by this paradigm in the decision-making process to protect the public in nuclear emergencies in the past may have, unwittingly and unintentionally, caused more harm than good to some sections of the public. This seems to have been the case in the use of population evacuation as the principal protection response to the Chernobyl (1986) and Fukushima (2011) accidents. There is thus a need to develop improved guidelines or tools on how to apply radiation protection recommendations for the public compatible with the Principle of Justification in the event of any future major radiation emergencies. It can also be argued that the present radiation protection paradigm, with its emphasis primarily on the physical health detriments from radiation, should be more inclusive and needs to shift to a more holistic or total health approach than heretofore to include mental health effects associated with nuclear emergencies. For severe mental health effects, some of the consequences, such as suicide, can even be as or more severe than most physical detriments likely to be suffered by those affected.

A RESPONSABILIZAÇÃO DOS AGENTES PÚBLICOS POR FRAUDES NAS AQUISIÇÕES PÚBLICAS DURANTE A PANDEMIA DE COVID-19

This is a scientific production whose theme is the accountability of public agents for fraud in public procurement during the COVID-19 pandemic. The Law of Administrative Improbity has been standing out in several aspects of the legal system and evolving in terms of legal and current protection, giving concreteness to the constitutional demand of art. 37, § 4.º, in order to effectively protect administrative morality, valuing honesty in dealing with public matters. For this, penalties have been sanctioned when there is disrespect for probity. This work was dedicated to analyzing the cases of accountability of public agents for fraud in acquisitions during the pandemic period of COVID-19, making an analysis of the concepts brought by the doctrinators and characterizing the improbable conduct, based on the principles of the Federal Constitution of 1988 and especially in compliance with Law No. 14230/21, which provides for administrative impropriety. The methodology used was a descriptive and exploratory literature review, with a qualitative approach. Regarding the results obtained, it is correct to state that during the pandemic period, mainly between the years 2020 and 2021, several public agents were involved in embezzlement, as shown in cases I, II, III and IV. As a result, there is passive corruption, which is practiced by the public agent who requests or receives, for himself or for another person of his interest, either directly or indirectly, any undue advantage due to the position he occupies.

The coupling effect of calcined layered double hydroxides and impressed current cathodic protection system on chloride ion binding and migration of sea sand mortar

Chloride introduced by sea sand and sea water leads to steel bar corrosion. Calcined Layered double hydroxides (CLDH) and impressed current cathodic protection (ICCP) system were used to adsorb chloride ion and control steel bar corrosion in chloride abundant environment. In this research, chloride binding effect of two kinds of CLDH were investigated in simulated concrete pore solution. Besides, chloride absorption capacity and steel bar corrosion resistance of Mg-Al CLDH was explored in mortar. Further, hydration degree of mortar installed ICCP system and migration of ions around the anode and cathode were detected. Results show that Mg-Al CLDH exhibits excellent chloride binding capacity and corrosion resistance. After installing the ICCP system, corrosion of steel bars in mortar mixed Mg-Al CLDH was controlled. And ions in mortar specimen around anode or cathode exhibits migration phenomenon in different degree. A two stage-four step model was established to explain the degradation of hydration products and ion migration in CLDH-ICCP system. Under the ICCP system, Cl− in pore solution increased at early stage and then decreased both around anode and cathode, the increment process was controlled by desorption of Mg-Al CLDH and decreased process was controlled by degradation of hydration products. Therefore, the CLDH-ICCP system was recommended to solve the problem of steel bar corrosion introduced by marine environment.

Enhanced Kullback–Leibler Divergence Based Pilot Protection for Lines Connecting Battery Energy Storage Stations

In light of the challenges faced by existing protection methods when battery energy storage station (BESS) and various nonideal conditions emerge, enhanced Kullback–Leibler divergence-based time-domain pilot protection is put forward in this article. Given the discrepancy in current waveforms between internal and external faults, KLD is employed to quantify the degree of similarity between two current waveforms, enabling the accurate distinction between internal and external faults. To eliminate the asymmetry of KLD, improved KLD(IKLD) is introduced. Whereafter, a technique is proposed to convert the current sampling sequence into a probability distribution that can be utilized by IKLD. To counteract the negative influence of current transformer(CT) saturation on IKLD-based protection, the time-domain waveform features of summation current are adequately employed to develop an enhanced KLD(EKLD). Further, high and low thresholds are legitimately designed to ensure both dependability and security. The flowchart of EKLD-based pilot protection is described, and its effectiveness is extensively validated by variation in fault resistance, location, type and operating mode of BESS using PSCAD and a hardware-in-the-loop(HIL) testing platform. Additionally, proposed protection outclasses power frequency component-based current differential protection and some up-to-date presented time-domain protection methods.

Research on detection and protection technology of DC residual current

Abstract To realize that the residual current device can accurately and quickly detect the fault when the fluctuating DC residual current occurs in the system and improve the system’s safety, a DC residual current detection and protection method based on VMD was proposed. Particle Swarm Optimization (PSO) was used to optimize the penalty factor and the number of decomposition layers of VMD. The minimum envelope entropy of the residual current signal is used as the fitness function to obtain the optimal combination. The criterion of fault occurrence is established based on the optimal modal component mutation characteristic of the residual current decomposed by VMD. Experiments show that this method can identify faults quickly and effectively when pulsating DC residual current is generated in the system.

Attitudes Towards Parents with a Diagnosis of Borderline Personality Disorder in Child Protection Settings

BackgroundParents diagnosed with borderline personality disorder (BPD) have high rates of child protection involvement. Research has shown that this diagnosis carries a significant amount of stigma. In the absence of standardised procedures for parenting capacity assessments within the child protection sector, the risk of stigma contributing to the decision-making process is high. ObjectiveThis study examined if there were differences in how students and practitioners rated parenting capacity based on parenting scenarios where a parent had a diagnosis of BPD compared to a parent diagnosed with postnatal depression. Participants and settingThe sample included 122 current, past, and prospective child protection workers who were recruited via social media and a local University. MethodsParticipants completed an online survey which included demographic questions and rated parenting capacity based on two vignettes involving two scenarios (one where a parent had a diagnosis of borderline personality disorder and post-natal depression in the other), along with general attitudes towards people with a diagnosis of BPD. ResultsThe parent in the borderline personality disorder vignette was assessed as having poorer parenting capacity compared to the parent in the postnatal depression scenario. Interestingly, there was no significant association between the assessment of parenting capacity and participants general attitudes and skills towards people with a diagnosis of BPD. Differences between the ratings of professionals and students are described. ConclusionsFurther training providing psychoeducation BPD is recommended to reduce the potential impact of stigma on decision-making, particularly for professionals within child protection settings.

Who takes the lead: Synergistic emission reduction effects of proactive government and efficient market in atmospheric pollution mitigation

In environmental protection, government and market forces must work together. However, existing literature often separates the two and discusses their roles independently. Therefore, this study incorporates both the market and government into a unified analytical framework. It redefines government force as environmental regulation and market force as allocation efficiency in environmental protection. The study empirically examines the synergistic emission reduction effects of active government and efficient market on air pollution, using data from 272 prefectural-level cities in China from 2003 to 2019. The results show: (1) Both government and market interventions can significantly reduce air pollution levels, and their combination achieves a synergistic emission reduction effect.(2) Within this synergy, government intervention remains dominant, while the market plays a supportive role. (3) Analyzing the heterogeneous effects under different scenarios reveals that collaboration and mutual monitoring between the government and the market can effectively counteract the adverse effects of economic policy uncertainty and corruption on the environment. Furthermore, when a single entity undertakes environmental protection, it may encounter issues of diminishing effectiveness over time. However, the synergistic effects of government and market cooperation can mitigate these challenges. (4) The synergy exhibits a threshold effect based on the varying strengths of government and market forces. (5) Public participation enhances the synergistic emission reduction effect of government and market, acting as a vital complement to their environmental protection efforts. This study provides new empirical evidence on the synergistic effect of current environmental protection measures in improving air pollution control.

The Infringement of Deepfake Technology on Personal Privacy and Legal Protection: A Discussion Based on Article 1032 of the Civil Code

The rapid development of deepfake technology has infringed upon personal privacy in the form of the disclosure and misuse of personal information, infringement upon the peace of people's life, and damage to personal image and reputation. The disclosure and misuse of personal information should be analysed from the perspectives of personal use and commercial use of information data; infringement upon the peace of people's life should be examined from the perspectives of fraud and harassment, and malicious pursuit using deepfake technology; and damage to personal image and reputation should be discussed from the two levels of initial damage to personal image and reputation and aggravated damage to personal reputation after dissemination through the media. Article 1032 of the Civil Code clearly defines the scope of privacy protection as the peace of people's private life, private space, private activities and private information, as well as the infringement of privacy rights through means such as spying, intrusion, disclosure and publication, which reflects the legislative inertia to strengthen the protection of privacy and personal information. Article 1032 of the Civil Code, the Personal Information Protection Law, the Provisions on the Administration of Deep Synthesis of Internet-based Information Services, and other laws and regulations together form the current personal privacy protection system. However, existing laws do not provide specific explanations for key terms such as 'leakage', 'intrusion' and 'damage', which leads to uncertainty in the application of the law and makes it difficult to effectively protect personal privacy in actual operations. At the same time, there is a lack of clear definitions of the scenarios and specific standards of behaviour that the technology may involve, which has exacerbated public concerns about personal privacy security. Strengthening legal protection against deepfake technology requires refining legal concepts and drawing on knowledge from comparative law: 'leakage' can be considered the illegal acquisition and dissemination of unauthorised data and information, 'intrusion' can be defined as behaviour that disrupts the normal order of others and causes mental distress, and 'damage' can be understood as behaviour that causes negative evaluation or loss to the image, reputation or property of others. The legislative department should take the lead and cooperate with the Ministry of Industry and Information Technology in formulating specific standards for evaluating behaviour. The deterrent effect of the law should be strengthened by refining relevant legal provisions in the Civil Code and the Personal Information Protection Law and increasing the penalties for violations of the law. This will better balance technological development and personal privacy protection and improve China's personal privacy protection system.

Trademarks in the Digital Age: The Current Challenges and Legal Protections

Abstract: In today's highly dynamic and rapidly evolving digital society, trade marks are experiencing profound transformations, presenting unique opportunities for trade mark owners to reach a broader and more diverse audience, thereby significantly enhancing brand visibility and recognition. However, these advancements also bring forth potential challenges, particularly directly related to trade mark rights infringement. Consequently, this dissertation delves deeply into the typical and recurrent conflicts that inevitably arise in relation to trade marks within the digital sphere by assessing the dilemma of existing representative cases, concluding that the central disputes existed. Additionally, it undertakes an in-depth exploration of the existing legal frameworks that govern this domain. Finally, this emphasizes the need for stronger international regulation of trademark rights across digital platforms. It is important to have the support of all parties involved in commercial actions to maintain a harmonious trading environment in the digital world while respecting the rights of trademark owners and maximizing profits from this flexible context.

Neurorights: Time to Discuss Rights to Mental Privacy and Integrity

The aim of this paper is to describe how artificial intelligence, algorithms, and deep learning can influence fundamental rights such as privacy and integrity. The authors consider the current protection of these rights the international level with a focus on Russian and European legislation. The authors also discuss whether AI poses a new threat to the protection of fundamental rights, and whether new laws should be established to deal with those violations. The study involves qualitative research methods, aimed at understanding people’s beliefs, experience, attitudes, behaviour, their interactions with social media and AI, as well as the analysis of sources of international and domestic law. The results have implications for new well-being interventions which look at the relationship between the internet and AI and their influence on individual privacy and mental integrity. The authors attempt to evaluate whether the right to privacy requires any special protection in the age of artificial intelligence, and if so, what do we mean by rights to mental privacy and integrity?

A short-circuit protection scheme for active distribution networks based on improved adaptive current reliability coefficient

Abstract Addressing the issue of misoperation in traditional three-zone current protection caused by the assisted, drawdown, or reverse current due to the large-scale integration of distributed generation (DG) into distribution networks (DNs), an adaptive current short-circuit protection scheme based on local information is proposed for active DNs (ADNs). Firstly, the adaptive current protection reliability coefficients are improved for the setting of protection zones I and II of the lines in the ANDs. On the DG side, an improved reliability coefficient is constructed using an e-exponential function. Subsequently, the distance between the fault point and the busbar is calculated by analyzing the relation between the positive-sequence voltage and positive-sequence current at the measuring point when faults occur at various locations. Based on this distance parameter, the reliability coefficient is adjusted in real time. Finally, the modified adjustable reliability coefficient, along with the online-calculated equivalent impedance and equivalent electromotive force, is used to coordinate the setting of short-circuit protection zones I and II of the lines in the ADNs. Simulation results demonstrate that, compared with traditional adaptive current protection schemes, this proposed scheme is independent of the location of short-circuit fault points, the grid-connected capacity, or the number of DGs, exhibiting better selectivity and reliability.

The Sibling Sexual Behaviour Mapping Tool (SSBMT): Supporting practitioner confidence, planning and competency when responding to sexual behaviours between siblings

ObjectivesThis paper outlines the development and initial pilot of the Sibling Sexual Behaviour Mapping Tool (SSBMT). Building on the findings of the National Project on Sibling Sexual Abuse (King-Hill, McCartan, et al., 2023) and work by Yates and Allardyce (2023), the tool was devised with the aim of supporting frontline child-protection social workers during the initial stages of working with families where sibling sexual behaviours (SSB) may be present. MethodsThis paper explores the rationale for the SSBMT design, and preliminary findings from the first phase of resource evaluation. The evaluation process comprised a small pilot with social workers across seven local authorities in the United Kingdom (UK). The pilot study sought to assess the workability and effectiveness of the SSBMT within social work practice, providing stakeholder insight prior to its launch. The study employed mixed methods to gain feedback on the SSBMT design, accessibility, ease of use and compatibility with current child protection work processes, which included training of 50 practitioners, surveys with 20 professionals and two semi-structured interviews. FindingsThe findings suggest that the SSBMT increased practitioner confidence when working with SSB, and promoted holistic, whole-family approaches in the initial stages of work with children and families affected by SSB.

Terrestrial land use signals on groundwater fauna beyond current protection buffers.

Terrestrial and aquatic ecosystems are tightly linked, with direct implications for applied resource management and conservation. It is well known that human land use change and intensification of terrestrial systems can have large impacts on surface freshwater ecosystems. Contrastingly, the study and understanding of such land use impacts on groundwater communities is lagging behind. Both the impact strength of land use on groundwater communities and the spatial extents at which such interlinkages are operating are largely unknown, despite our reliance on groundwater for drinking water extraction as a key ecosystem service. Here, we analyzed groundwater amphipod occurrence from several hundred shallow groundwater aquifers used for drinking water extraction across a region of varying agricultural intensity and human population density in Switzerland. Despite drinking water extraction sites being generally built at locations with expected minimal aboveground impacts on water quality, we found a direct correlation between land use type and intensity within the surrounding catchment area and the locally measured nitrate concentrations, which is a direct proxy for drinking water quality. Furthermore, groundwater amphipods were more likely to be found at sites with higher forest coverage than at sites with higher crop and intensive pasture coverages, clearly indicating a tight connection between aboveground land use and groundwater biodiversity. Our results indicate that land use type effects on groundwater communities are most relevant and pronounced to spatial scales of about 400-1000 m around the groundwater sampling site. Importantly, the here identified spatial scale is 1.2- to 3-fold exceeding the average extent of currently defined groundwater protection zones. We postulate that incorporating an ecosystem perspective into groundwater management strategies is needed for effective protection of groundwater quality and biodiversity.

SARS-CoV-2 outbreak in lions, tigers and hyenas at Denver Zoo.

In late 2019, SARS-CoV-2 spilled-over from an animal host into humans, where it efficiently spread, resulting in the COVID-19 pandemic. Through both natural and experimental infections, we learned that many animal species are susceptible to SARS-CoV-2. Importantly, animals in close proximity to humans, including companion, farmed, and those at zoos and aquariums, became infected, and many studies demonstrated transmission to/from humans in these settings. In this study, we first review the literature of SARS-CoV-2 infections in tigers and lions, and compare species, sex, age, virus and antibody detection assay, and types, frequency and length of clinical signs, demonstrating broad heterogeneity amongst infections. We then describe a SARS-CoV-2 outbreak in lions, tigers and hyenas at Denver Zoo in late 2021. Animals were tested for viral RNA (vRNA) for four months. Lions had significantly more viral RNA in nasal swabs than both tigers and hyenas, and many individual lions experienced viral recrudescence after weeks of undetectable vRNA. Infectious virus was correlated with high levels of vRNA and was more likely to be detected earlier during infection. Four months post-infection, all tested animals generated robust neutralizing antibody titers. Animals were infected with Delta lineage AY.20 identical to a variant circulating at less than 1% in Colorado humans at that time, suggesting a single spillover event from an infected human spread within and between species housed at the zoo. Better understanding of epidemiology and susceptibility of SARS-CoV-2 infections in animals is critical to limit the current and future spread and protect animal and human health.

Development and Prospect of Space Debris Protection Structures for Spacecraft

Background: As the pace of human conquest of space continues to accelerate, the number of spacecraft carrying out various activities in space continues to increase, so that the available orbital space continues to decrease, the amount of space debris continues to increase, and thus the probability of orbiting spacecraft being impacted by space debris is also increasing. Research on the development of protective structures in the current state is conducive to improving the protection performance of spacecraft protective structures against space debris, reducing the occurrence of spacecraft disintegration events and spacecraft collision events, and may also promote the development of many fields through the development of new technologies. Aim: Through the latest application and development of spacecraft, the advantages and disadvantages of various protection structures are summarized, and the development trend of academic and aerospace protection engineering is analyzed. Methods: Through the latest representative patent research methods for spacecraft space debris, research content, and creative structure, the principle and characteristics of the protective structure are demonstrated. Results: By comparing the application of different spacecraft space debris protection structures, the existing problems of the current protection structures are listed, and the potential development paths and research topics are put forward Conclusion: The development of aerospace, military, and other industries benefit from the development of protective structures, and the composite spacecraft space debris protection structures have broad development prospects.

Combined Wind Turbine Protection System

The increasing deployment of wind turbines in technologically advanced nations underscores the need to enhance their reliability, extend their operational lifespan, and minimize failures. The current protection devices for wind turbine components do not sufficiently shield them from various external factors that degrade performance. This study addresses the environmental and technical challenges that disrupt wind turbine operations and reviews existing research and technical solutions for protecting individual components, supported by experimental findings. Using a decomposition method followed by the integration of protection components, we propose a combined protection system designed to improve the overall resilience of wind turbines. The proposed system aims to reduce incidents, extend service life, and increase reliability, addressing a critical gap in wind energy technology and contributing to its continued development and efficiency.

AI and Actors: Ethical Challenges, Cultural Narratives and Industry Pathways in Synthetic Media Performance

The article explores the growing use of artificial intelligence (AI) in the entertainment industry, focusing on the impact to screen and audio performers. AI technologies enable the creation of synthetic performances, raising ethical concerns regarding identity manipulation, consent, and performer rights. Ethical AI should prioritize human-centric values such as transparency, accountability, and fairness, but many principles remain abstract and difficult to implement. Examining the intersection of acting and AI – in terms of working practice and discursive narratives used to situate that work – highlights significant issues about responsible AI use, the mechanics of media production, and the management of digitised identities. It stands as a useful model through which to explore and advance concepts of responsible AI practice and rhetoric. The article examines the role of fraudulent and exploitative uses of performer likenesses, how synthetic performance is enhancing celebrity brand identities, and evolving regulatory measures governing performer intellectual property (IP) across the U.S. and UK media industries. Performers are increasingly negotiating licensing and legal agreements to protect their likenesses, but current protections benefit primarily well-known stars over others. The article underscores the need for systemic frameworks to ensure responsible AI use, emphasizing the critical role performers play as both data sources and cultural agents, influencing public trust in AI technologies.

Redefining Protection: Challenges and Solutions in Safeguarding Religious Minorities within International and Regional Legal Frameworks

This paper examines the challenges in defining and safeguarding religious minorities within international and regional legal frameworks. It explores the main research question of how existing legal instruments and definitions impact the protection of religious minorities and aims to propose recommendations for improving these protections. Through a literature review and critical analysis of international and regional legal frameworks, including the Universal Declaration of Human Rights, the International Covenant on Civil and Political Rights, and various regional instruments, the paper identifies significant gaps and inconsistencies in current protections. Key issues highlighted include the lack of a universally accepted definition of religious minorities, the limitations of international and regional instruments, and the varying interpretations of religious rights by bodies such as the European Court of Human Rights. The paper concludes with recommendations for clearer definitions, more robust legal provisions, and enhanced international and regional cooperation to better safeguard the rights of religious minorities. The findings emphasize the need for more effective approaches to protecting religious diversity and ensuring proper representation.
