Two-stage ship detection at long distances based on deep learning and slicing technique
Authors: Gong Yanfeng , Chen Zihao , Tan Jiawan , Yin Chaozhong , Deng Wen
Published: November 2024

Ship detection over long distances is crucial for the visual perception of intelligent ships. Since traditional image processing-based methods are not robust, deep learning-based image recognition methods can automatically obtain the features of small ships. However, due to the limited pixels of ships over long distances, accurate features of such ships are difficult to obtain. To address this, a two-stage object detection method that combines the advantages of traditional and deep-learning methods is proposed. In the first stage, an object detection model for the sea-sky line (SSL) region is trained to select a potential region of ships. In the second stage, another object detection model for ships is trained using sliced patches containing ships. When testing, the SSL region is first detected using the trained 8th version of You Only Look Once (YOLOv8). Then, the SSL region detected is divided into several overlapping patches using the slicing technique, and another trained YOLOv8 is applied to detect ships. The experimental results showed that our method achieved 85% average precision when the intersection over union is 0.5 (AP50), and a detection speed of 75 ms per image with a pixel size of 1080×640.

Published: November 2024

Background

Extreme weather is a recognised risk factor for stillbirth and preterm birth, disrupts women’s access to healthcare during pregnancy and childbirth, and negatively affects the care of newborns. Reliable and accessible heat and weather warning systems are key in alerting individuals to undertake protective measures. There is a notable gap in understanding how women and caregivers in rural East Africa perceive and utilize weather information. We investigated community members’ heat and weather warning information-seeking behaviour, identified available sources, assessed their reliability and utility, and examined their influence on behaviour.

Settings

Our research was conducted in rural Kilifi County in Kenya’s coastal region. The area experiences temperatures exceeding 23°C throughout the year, with extended periods of extreme temperatures [> 40°C] and long and severe droughts.

Methods

We conducted in-depth interviews [IDI] with pregnant and postpartum women [n = 21] and held six focus group discussions [FGDs] involving mothers-in-law and community health volunteers [CHVs]. The data were analysed in NVivo 12 using both inductive and deductive approaches.

Results

We found significant gaps concerning pregnant and post-partum women, and their caregivers, having timely access to weather forecasts and heat information from health or meteorological authorities. Information on heat and weather warnings is disseminated through various channels, including television, radio, mobile phones, and word of mouth, which are facilitated by community influencers such as CHVs and local chiefs. Indigenous methods of weather forecasting, such as cloud observation, consulting local “rainmakers”, and studying the behavioural patterns of amphibians, are employed in conjunction with warnings from the Kenyan Meteorological Department (KMD). Barriers to accessing weather information include the cost of television and smartphones and a lack of segmented information in local languages.

Conclusions

National and county meteorological services need to enhance public participation, communication, and the delivery of heat and weather information to guide community-level response measures and individual behaviour change. They should also collaborate with health professionals to address heat risks for vulnerable groups. Further research is needed to empower indigenous weather predictors with modern weather information and revise national policies to deliver tailored messages to vulnerable populations like pregnant and postpartum women.

Many maternal and neonatal deaths can be avoided if quality healthcare is provided. To this end, the South African National Department of Health implemented a quality improvement (QI) programme (2018–2022) to improve maternal and neonatal health services in 21 public health facilities. This study sought to identify good practices aimed at improving QI teams’ performance by identifying optimal facility-level contextual factors and implementation processes. We purposively selected 14 facilities of the 21 facilities for a longitudinal qualitative process evaluation. We interviewed 17 team leaders, 47 members, and five QI advisors who provided technical support to the teams. The data were analysed using framework analysis. We choose the Consolidated Framework for Implementation Research as framework given that it explicates contexts and processes that shape programme implementation. Six quality improvement teams were assessed as well-performing, and eight as less well-performing. This research conceptualises a ‘life course lens’ for setting up and managing a QI team. We identified eight good practices, six related to implementation processes, and two contextual variables that will optimise team performance. The two most impactful practices to improve the performance of a QI team were (i) selecting healthcare workers with quality improvement-specific characteristics, and (ii) appointing advisors whose interpersonal skills match their technical quality improvement competencies.
“The million-euro answer”: party youth wings’ views on the opportunities and challenges of engaging young people politically through social media
Authors: Machado Sara , Ribeiro Vasco , Meneses Raquel
Published: November 2024

Research on the relationship between youth, politics, and social media often overlooks the role and views of party youth wings. In this study, we seek to fill this gap by understanding (1) the objectives guiding the political communication of party youth wings on social media and (2) the opportunities and challenges they identify in the process. We do so by conducting semi-structured interviews with representatives of youth wings and informal youth groups from Portuguese political parties. Information emerges as the primary communicational objective of youth wings, who do not consider social media an ideal space for political dialogue. Although social media is the main communication channel with young people, offering more reach, flexibility, and feedback opportunities, several challenges limit the effectiveness of communication: resources, algorithms, audience fragmentation, selection effects, simplification of complexity, and the irreplaceability of face-to-face contact. The implications of these results are discussed.

O setor de saneamento básico enfrenta diversos desafios relacionados ao cumprimento de metas ambientais, melhoria das condições sociais, otimização de recursos econômicos, competência dos prestadores e processo de regionalização, bem como fatores políticos, devido ao papel dos gestores públicos na administração de recursos. Neste estudo, objetivou-se analisar os efeitos dos ciclos eleitorais e outros determinantes nas despesas de exploração dos serviços de abastecimento de água e esgotamento sanitário em governos locais. Nesse propósito, utilizaram-se dados do Sistema Nacional de Informações sobre Saneamento e a modelagem de dados em painel para analisar o período de 2012 a 2020, que incluiu três eleições municipais (2012, 2016 e 2020). Os resultados revelam a presença de ciclos políticos eleitorais em governos locais, sendo que municípios de pequeno porte apresentaram um gasto médio maior em saneamento em comparação aos municípios de grande porte. Esses achados contribuem para a compreensão do cenário nacional dos serviços de saneamento básico no Brasil, especialmente no contexto das discussões sobre competência e regionalização desses serviços, auxiliando na formulação de políticas públicas.
Lernerfahrungen im Feld der Komparativen Theologie. Ein Werkstattbericht
Authors: Stosch Klaus von
Published: November 2024

Comparative theology originally developed from the encounter with Eastern religions. As a result, it lacks concrete theological discussions with other religions in their theological self-understanding. While the theology of Israel has seemingly always been a breaking point for all theologies of religions, the article aims to show that Qurʾanic theology also holds its own challenges for Christianity, which must be addressed in contemporary comparative theological research. Especially the insight that many Qurʾanic interventions in Christological debates are dependent on a critique of the imperial political theology of Byzantium challenges traditional views on Muslim-Christian relations. But also recent ecumenical approaches to the Qurʾanic theology of Abrahamic religions have to be reflected.
Buddhistische Verhältnisbestimmungen zu anderen Religionen
Authors: Jäger Stefan S.
Published: November 2024

This article explores some basic Buddhist attitudes towards other religions as found in the history of the spread of Buddhism in Asia and, since the 19th century, in the Americas and Europe. In the encounter with other religious traditions, Buddhist formations prove to be highly adaptable and integrative in terms of specific elements, while holding on to fundamental insights. Particular emphasis is placed on Buddhist meta-communicative concepts and terminology. Since Buddhism is basically a non-theistic religion, its encounter with theistic religions can be characterized as asymmetrical.

Exploring the feasibility of using drones for seeding of rice (Oryza sativa. L.)
Authors: Adithya K , Ramesh T , Rathika S , Vanniarajan C , Raja K
Published: November 2024

Rice planters worldwide face increasing challenges such as water scarcity, labor shortages and rising production costs. Traditional rice production techniques are time-consuming, labor-intensive, less economical, and more susceptible to the excessive use of farm inputs. These conditions necessitate an advanced crop establishment technique that offers higher returns with lower input and labor than traditional methods. A field study was performed to assess the viability of employing drones for rice planting compared to alternative establishment methods concerning rice productivity. The treatments consisted of four different seed rates (30, 40, 50, and 60 kg ha?¹) for drone seeding, compared with drum seeding, manual broadcasting, and transplanting. The performance of drone seeding was assessed using various growth and yield parameters. Transplanted rice exhibited significantly higher growth, yield parameters, and grain yield than other methods; however, it was economically inferior to direct seeding methods, either by drum seeder or drones. Direct seeding using a drum seeder at 30 kg ha?¹ and drone seeding at 40 kg ha?¹ produced comparable growth and yield. Notably, drone seeding with a 40 kg ha?¹ seed rate resulted in significantly higher growth, yield parameters, and overall yield than manual broadcasting. This method saved 20 kg ha?¹ of seeds and increased rice yield by 13% compared to manual broadcasting at 60 kg ha?¹. Considering the issues of labor scarcity, timeliness of operation, and cost of establishment, drone seeding at a rate of 40 kg ha?¹ is deemed a more sustainable and forward-looking technique for rice crop establishment.

Authors: Kett Natasha , Spray Erika , Rutherford Nate , Rendoth Tess
Published: November 2024

Simulated learning environments have rapidly evolved in recent years and are gaining traction as an effective tool in teacher education (Australian Institute for Teaching and School Leadership, 2023; Frei-Landau et al., 2023). This paper explores the use of virtual classroom simulation in initial teacher education at an Australian university. It considers the alignment of simulation activities with mandated learning outcomes, and the challenges in assessing simulation-based learning in ways which are fair, authentic and effective. These issues are analysed within a detailed review of how simSchool, an online virtual classroom gaming platform, has been innovatively integrated within the curriculum and assessment of three undergraduate initial teacher education courses. Each case study report includes an instructor-led evaluation of key elements of the assessment design process, enabling comparison of the different strengths of each approach. The paper concludes by summarising the salient aspects of successful integration and assessment of simulation technology in higher education. This contribution to the discourse of simulation pedagogy seeks to encourage more academics to test the affordances of simulation technology in their teaching by adopting approaches that are tailored for student cohorts and precisely aligned with learning outcomes.
 
Implications for practice or policy:

Academics should tailor simulation activities for their cohort and learning objectives.
Assessment must be precisely aligned, fair, authentic and effective.
Learner engagement may be increased by careful introduction and management of expectations, with clarification of learning opportunities.
Ongoing evaluation of simulation activities and assessment is important to maintain high quality teaching and learning.

Published: November 2024

Primary biliary cholangitis (PBC) is an autoimmune liver disease. During the diagnostic process, the patient’s autoimmune antibodies are routinely examined. Approximately 20% of PBC patients have positive anti-centromere antibody (ACA). We evaluated the clinical characteristics of ACA-positive and ACA-negative PBC patients to explain the differences in disease progression between these two groups. Retrospective data from 961 PBC patients at Beijing Youan Hospital from 2010 to 2019 were gathered and separated into two groups based on ACA positivity. We collected and evaluated clinical laboratory indices, gastroscopy findings, and liver function assessments. In addition, 60 liver biopsies were available for comparison between the 2 groups. Pathologists staged the histological findings using the Ludwig staging criteria and Nakanuma staging and grading. Immunohistochemical staining was also performed on liver biopsies to examine the expression of cytokeratin 7 (CK7) in the tissue. A synthesis of clinical indicators in the large cohort showed that alanine transaminase, aspartate aminotransferase, total bilirubin, IgG, white blood cell, and platelet were significantly lower in the ACA-positive group, indicating that the overall status of liver injury was more moderate in the ACA-positive group. Additionally, ACA-positive patients in the non-cirrhotic group were more likely to present with gastroesophageal varices related to portal hypertension. Finally, analysis of pathologic findings showed that parameters were mostly comparable in the two groups, but CK7 differed and was more significantly lower in the ACA-positive group in albumin–bilirubin grade 2 and 3 patients. In summary, we characterized and compared the clinical features of ACA-positive and ACA-negative PBC patients, corroborating previous studies on the relationship between ACA positivity and portal hypertension cross-sectionally. It suggested that gastroesophageal varices might happen in the earlier course of PBC natural progression in the ACA-positive group.

Published: November 2024

Dopaminergic neurotransmission plays a crucial role in motor function through the coordination of dopamine receptor (DRD) subtypes, such as DRD1 and DRD2, thus the functional imbalance of these receptors can lead to Parkinson's disease. However, due to the complexity of dopaminergic circuits in the brain, it is limited to investigating the individual functions of each DRD subtype in specific brain regions. Here, we developed a light-responsive chimeric DRD2, OptoDRD2, which can selectively activate DRD2-like signaling pathways with spatiotemporal resolution. OptoDRD2 was designed to include the light-sensitive component of rhodopsin and the intracellular signaling domain of DRD2. Upon illumination with blue light, OptoDRD2 triggered DRD2-like signaling pathways, such as Gαi/o subtype recruitment, a decrease in cAMP levels, and ERK phosphorylation. To explore unknown roles of DRD2 in glutamatergic cell populations of basal ganglia circuitry, OptoDRD2 was genetically expressed in excitatory neurons in lateral globus pallidus (LGP) of the male mouse brain. The optogenetic stimulation of OptoDRD2 in the LGP region affected a wide range of locomotion-related parameters, such as increased frequency of movement and decreased immobility time, resulting in the facilitation of motor function of living male mice. Therefore, our findings indicate a potentially novel role for DRD2 in the excitatory neurons of the LGP region, suggesting that OptoDRD2 can be a valuable tool enabling the investigation of unknown roles of DRD2 at specific cell types or brain regions.

Published: November 2024

Смешанные кристаллы бетулина с дикарбоновыми кислотами получены с помощью механохимической активации при добавлении небольших количеств органических растворителей. Образование смешанных кристаллов подтверждено методами рентгенофазового анализа, термического анализа, ИК-спектроскопии. Для образования смешанных кристаллов важны присутствие растворителя, оптимальное соотношение компонентов, продолжительность механической обработки. С целью обоснования выбора растворителя для приготовления смешанных кристаллов бетулина проведено сравнение растворителей различной полярности. Показано, что смешанные кристаллы образуются, если при механической обработке используются растворители, способные эффективно растворять дикарбоновую кислоту. Для сравнения с механохимическим методом смешанные кристаллы бетулина были получены при нагревании смеси исходных реагентов. Наблюдаемые с помощью сканирующей электронной микроскопии морфологические изменения при нагревании реакционных смесей также свидетельствуют об образовании смешанных кристаллов. Показано, что при растворении смешанных кристаллов в воде образуются растворы с повышенной концентрацией бетулина, причем увеличение длины алифатической цепи кислоты приводит к снижению скорости выделения бетулина в раствор.

Cocrystals of betulin with dicarboxylic acids were obtained using mechanochemical treatment with the addition of small amounts of organic solvents. The formation of cocrystals was confirmed by powder X-ray diffraction, thermal analysis, and IR spectroscopy methods. The presence of a solvent, the optimal components ratio, and the duration of mechanical processing are important for the formation of cocrystals. In order to choose a solvent for preparing betulin cocrystals, the solvents of different polarity were compared. It has been shown that cocrystals are formed if solvents that can effectively dissolve dicarboxylic acid are used during mechanical processing. For comparison with the mechanochemical method, betulin cocrystals were obtained by heating a mixture of starting reagents. Morphological changes observed by scanning electron microscopy upon heating the reaction mixtures also indicate the formation of cocrystals. It has been shown that when cocrystals are dissolved in water, solutions with an increased concentration of betulin are formed, and an increase in the length of the aliphatic chain of the acid leads to a decrease in the rate of betulin release into the solution.

Published: November 2024

There are different deep neural network (DNN) architectures and methods for performing augmentation on time series data, but not all the methods can be adapted for specific datasets. This article explores the development of deep learning models for time series, applies data augmentation methods to conveyor belt (CB) tension signal data and investigates the influence of these methods on the accuracy of CB state classification. CB systems are one of the essential elements of production processes, enabling smooth transportation of various industrial items, therefore its analysis is highly important. For the purpose of this work, multi-domain tension data signals from five different CB load weight conditions (0.5 kg, 1 kg, 2 kg, 3 kg, 5 kg) and one damaged belt condition were collected and analysed. Four DNN models based on fully convolutional network (FCN), convolutional neural network combined with long short-term memory (CNN-LSTM) model, residual network (ResNet), and InceptionTime architectures were developed and applied to classification of CB states. Different time series augmentations, such as random Laplace noise, drifted Gaussian noise, uniform noise, and magnitude warping, were applied to collected data during the study. Furthermore, new CB tension signals were generated using a TimeVAE model. The study has shown that DNN models based on FCN, ResNet, and InceptionTime architectures are able to classify CB states accurately. The research has also shown that various data augmentation methods can improve the accuracy of the above-mentioned models, for example, the combined addition of random Laplace and drifted Gaussian noise improved FCN model’s baseline (without augmentation) classification accuracy with 2.0 s-length signals by 4.5% to 92.6% ± 1.54%. FCN model demonstrated the best accuracy and classification performance despite its lowest amount of trainable parameters, thus demonstrating the importance of selecting and optimizing the right architecture when developing models for specific tasks.

Characterization of the response of a well chamber to different models of Ir-192 sources for HDR brachytherapy
Authors: Bernardino Alexandre , Souza Izabella , Hauradou Thais , Da Silva Ademir , Lima Inayá
Published: November 2024

The determination of the reference air kerma rate (KR) with well chambers calibrated using a different model of source than desired can lead to significant errors, affecting both radiological traceability institutions and healthcare facilities. This study employs the methodology proposed by SHIPLEY et al. (2015) with the PTW T33005 well chamber model and six models of HDR brachytherapy sources (microSelectron v.1; microSelectron v.2; Flexisource; GammaMed Plus; BEBIG GI192M11; Varisource VS2000) to derive correction factors for source geometry (KSG). These factors adjust the chamber calibration factor for air kerma (NK) to the source model under measurement. The methodology relies on simulating the chamber response to sources using the Monte Carlo Method (MC), specifically utilizing the MCNPX code. Both the source and well chamber models were validated by comparing dosimetric parameters from TG-43 and simulated calibration factors (MCNK) with literature-derived reference values. The normalized KSG values, relative to the microSelectron v.1 source, agree with reference values, demonstrating the methodology's applicability across various chamber models, sources, and MC codes. The corrections ranged from 0.984 to 1.001, with the most significant correction observed for the Varisource VS2000 source, yielding KSG = 0.984, corresponding to a -1.6% correction.
How Many Epistolary Novels Did Dostoevsky Write?
Authors: Zakharov Vladimir
Published: November 2024

Dostoevsky’s literary debut was his epistolary novel “Poor People.” Epistolary genres and subgenres are vital in many of the writer’s works. It can definitely be argued that Dostoevsky’s literary talent initially manifested itself in his letters to his brother Mikhail in 1838. Despite the ironic criticism of the genre, the author without any modesty called his letters “masterpieces of belles lettres.” This borrowing from the French chefs-d’euvre de la lettristique characterizes the young writer’s degree of ambition. The letters of Dostoevsky and his correspondents constitute a significant part of his literary heritage. They carry a huge aesthetic and artistic potential, which is underestimated in many ways. Critics and readers do not see the author as a poet and an artist, while Dostoevsky is a genius in any genre: whether novels, essays, feuilletons, or letters. The list of Dostoevsky’s correspondents included hundreds of addressees: extended family and relatives, friends and acquaintances, readers and fans, writers, critics and publishers, creditors and loan sharks, students and students of Higher women’s courses. Many of the writer’s interlocutors were prominent personas in Russia. Young women and divorced ladies wrote to him, asking for advice and guidance, and sometimes expecting mentoring in literary verse and prose work. The writer awakened in them the gift of words, imagination, and critical judgment. His readers comprised many who were congenial to the author. There are twelve works in Dostoevsky’s corpus of texts that he called novels, two of them epistolary — “Poor People” and “A Novel in Nine Letters.” There are more of them, if we turn to the writer’s epistolary legacy. Dostoevsky and his correspondents wrote letters, and they often served as the foundation of epistolary novels. The epistolary genre multiplies the collection of Dostoevsky’s novels, expands and enriches the creative legacy of the genius.

É importante reconhecer as necessidades únicas de indivíduos que vivem com deficiência, seja física ou intelectual. No Brasil, há 17,3 milhões de pessoas com deficiência, representando 8,4% da população acima de 2 anos. Desses, 49,4% possuem mais de 60 anos (IBGE, 2021).
ENVELHECIMENTO SAUDÁVEL DE CUIDADORES FAMILIARES DE PESSOAS COM DEMÊNCIA: DESAFIOS E PERSPECTIVAS
Authors: Carbone Anversa Andreisi , Elena Xavier de Oliveira Ligoski Eloisa , Bromberg Elke
Published: November 2024

A demência é uma condição progressiva e multifatorial, caracterizada por declínio das funções cognitivas e prejuízo na capacidade de realização de atividades diárias e sociais (Cipriani et al., 2020). Com o processo de envelhecimento global, a estimativa de pessoas com essa condição tem aumentado substancialmente. Em 2019, havia 55 milhões de indivíduos, no mundo, vivendo com demência; e projeções indicam que, em 2050, esse contingente será de 139 milhões (Gauthier et al., 2022).

O envelhecimento da população tem gerado o surgimento de atenção por parte de pesquisadores e investidores com o desenvolvimento de serviços e produtos para atender à parcela populacional que mais cresce nas estatísticas. Adaptar e planejar serviços que beneficiem diretamente as pessoas idosas com mais acesso, recursos e facilidades oportunizadas pelas tecnologias, tem sido prioridade inclusive para organismos internacionais como a OMS - Organização Mundial da Saúde e UIT - União Internacional de Telecomunicações (OPS e UIT, 2023).
Statistical inference for nth-order mixed fractional Brownian motion with polynomial drift
Authors: El Omari Mohamed
Published: November 2024

The mixed model with polynomial drift of the form $X(t)=\theta \mathcal{P}(t)+\alpha W(t)+\sigma {B_{H}^{n}}(t)$ is studied, where ${B_{H}^{n}}$ is the nth-order fractional Brownian motion with Hurst index $H\in (n-1,n)$ and $n\ge 2$, independent of the Wiener process W. The polynomial function $\mathcal{P}$ is known, with degree $d(\mathcal{P})\in [1,n)$. Based on discrete observations and using the ergodic theorem estimates of H, ${\alpha ^{2}}$ and ${\sigma ^{2}}$ are given. Finally, a continuous time maximum likelihood estimator of θ is provided. Both strong consistency and asymptotic normality of the proposed estimators are established.
Michaél Psellos teológiai munkái
Authors: Farkas Zoltán
Published: November 2024

Michaél Psellos teológiai munkái bevezetések és szövegmagyarázatok a Szentírás egyes helyeihez, különösen a Zsoltárokhoz. A tanköltemények és szónoki beszédek egyfelől a patrisztikus hagyomány nyomvonalát követik, elsősorban Teológus Szent Gergely és Hitvalló Maximos exegétikai munkáit, másfelől azonban más módon értelmezik és magyarázzák a korábban mások által tárgyalt szentírási helyeket. A dolgozat áttekintést ad Psellos teológiai műveiről, valamint példákon keresztül mutatja be szövegmagyarázati elveit és gondolatmeneteinek váratlan elemeit.
Szomorú trópusok. Pecz Vilmos (1854–1923) emlékezete
Authors: Farkas Zoltán
Published: November 2024

A tudománytörténeti dolgozat áttekintést ad Pecz Vilmos klasszikus filológus életéről, tudományos pályájáról és életművéről. Pecz a klasszikus görög költők szóképeit (τρόποι) gyűjtötte, rendszerezte és értelmezte irodalomtörténeti szempontból, különös tekintettel az úgynevezett aránytrópusokra (Proportionstropen). A kortársak és a közvetlen utókor megítélése szerint ez a kutatás zsákutcának bizonyult, de a kiadott gyűjtemények hasznos példatárként szolgálhatnak a mai metaforakutatók számára.
Cybersecurity Economics for Emerging Markets
Authors: Vergara Cobos Estefania
Published: November 2024

n our increasingly interconnected world, where digital technologies are rapidly transforming multiple aspects of daily life, the critical role of cybersecurity cannot be overstated, especially in developing nations. As these countries strive to harness the power of modern technology to drive economic growth, enhance public services, and elevate living standards, they concurrently face heightened risks associated with cyber threats. The increasing exposure of developing countries to cyber incidents is often compounded by various factors, including scarce resources, inadequate infrastructure, political unrest, inefficiencies in cybersecurity and technology markets, shortages of skilled cybersecurity professionals, legislative voids, and rapid rates of digital adoption. "Cybersecurity Economics for Emerging Markets" is a pioneering research work that delves into the drivers and profound consequences of cyber incidents worldwide. From economic setbacks that can destabilize entire economies to interruptions of vital services and impediments to social and economic development, the impacts of cyber incidents are far-reaching. This book analyzes hundreds of scholarly works and thousands of publicly disclosed cyber incidents over the past decade across some 190 countries. It sheds light on these incidents’ characteristics and trends, as well as the proactive roles that private market players and governments can assume to safeguard infrastructure in cyberspace effectively. The book presents practical, evidence-based policy suggestions that include efforts to strengthen the resilience of the most essential and interconnected sectors. It advocates for bolstering the national cybersecurity industries, strategizing cybersecurity research and development, addressing market failures through cybersecurity awareness and training programs, and taking proactive steps to reduce and control contagion effects from cyber incidents. By revealing crucial empirical and theoretical dimensions of cybersecurity economics, this book provides insights that could inform the creation of effective cybersecurity investments, with a focus on developing countries. These insights are invaluable for policy makers and stakeholders committed to fortifying the digital ecosystem against the ever-evolving landscape of cyber threats.
New Evidence on the US Excess Return on Foreign Portfolios
Authors: Bertaut Carol C. , Curcuru Stephanie E. , Faia Ester , Gourinchas Pierre-Olivier
Published: November 2024

We provide new estimates of the return on US external claims and liabilities using confidential, high-quality, security-level data. The excess return is positive on average, since claims are tilted toward higher-return equities. The excess return is large and positive in normal times but large and negative during global crises, reflecting the global insurance role of the US external balance sheet. Controlling for issuer's nationality, we find that US investors have a larger exposure to equity issued by Asia-headquartered corporations than reported in the aggregate statistics. Finally, equity portfolios are concentrated in 'superstar' firms, but for US liabilities foreign holdings are less concentrated than the overall market.

El deterioro de la naturaleza es una amenaza para la vida y sus diversos ecosistemas. La deforestación, la contaminación y el cambio climático están alterando los ecosistemas de todo el planeta, provocando eventos meteorológicos extremos, la extinción de especies y la degradación de la calidad de vida. Es urgente tomar medidas para revertir esta tendencia. Necesitamos cambiar nuestro modelo de producción y consumo, reducir nuestra dependencia de los combustibles fósiles y proteger los ecosistemas. Solo así podremos garantizar un futuro sostenible para las generaciones venideras.
