A Defensoria Pública, instituição permanente e essencial à função jurisdicional do Estado, atua na defesa dos interesses dos hipossuficientes e na promoção e proteção dos direitos humanos, incluindo o direito à saúde. Desde a Constituição de 1988, com a adoção do modelo de abrangência nacional – Defensoria Pública da União (DPU), Defensoria Pública do Distrito Federal e Territórios e Defensoria Pública dos Estados –, a instituição se consolida como um importante elemento na promoção do acesso à justiça aos mais vulneráveis. Analisar a atuação das Defensorias Públicas na seara do Direito Sanitário, nas dimensões judiciais e extrajudiciais, mostra-se um imperativo para compreender o papel da instituição na proteção e afirmação desse importante direito social, e um convite à reflexão sobre uma governança sanitária que seja, ao mesmo tempo, tecnicamente sólida e profundamente humana.

Soil organic matter (SOM) is a key indicator of cropland quality and carbon cycling. Accurate SOM mapping is essential for sustainable soil management and carbon sink assessment. This study investigated the effects of interannual climatic variability on SOM prediction using remote sensing and machine learning. Youyi Farm in the Sanjiang Plain, Heilongjiang Province, was selected as the study area, covering three representative years: 2019 (flood), 2020 (normal), and 2021 (drought). Based on multi-temporal Sentinel-2 imagery and environmental covariates, Random Forest models were used to evaluate single- and dual-period combinations. Results showed that combining bare-soil and crop-season images consistently improved accuracy, with optimal combinations varying by year (R² = 0.544–0.609). Incorporating temperature, precipitation, and elevation enhanced model performance, particularly temperature, which contributed most to prediction accuracy. Feature selection further improved model stability and generalization. Spatially, SOM showed a pattern of higher values in the northeast and lower in the central region, shaped by topography and cultivation. This study innovatively integrates interannual climatic variability with remote sensing temporal combination and feature selection, constructing a climate-adaptive SOM mapping framework and providing new insights for accurate inversion of cropland SOM under extreme climates, highlights the importance of multi-temporal imagery, environmental factors, and feature selection for robust SOM mapping under different climatic conditions, providing technical support for long-term cropland quality monitoring.

This paper provides a novel summary measure of ideological polarization in the American public based on the joint distribution of survey responses. Intuitively, polarization is maximized when views are concentrated at opposing extremes with little mass in between and when opinions are highly correlated across many issues. Using this measure, I show that public polarization has been increasing for the past three decades and that these changes are mostly due to increases in general disagreement, not dimensional collapse. Furthermore, these increases are not explained by the diverging opinions of Democrats and Republicans, nor divergence of opinions across gender, geography, education, or any other demographic divide.

This perspective posits that gene-environment interplay (GxE) studies should be developed both theoretically and empirically to be of relevance to policy makers. On the theoretical front, this development is essential because the current literature lacks the integration of a clear framework capturing the various goals of public policies. Empirically, GxE models need to be further developed because the common way of modelling GxE effects fails to adequately capture the heterogeneous effects public policies may have along the distribution of genetic propensities (as captured by polygenic indices). We fill these gaps by proposing a policy classification for GxE research and by offering guidance on advancing the empirical modelling of policy-informative GxE interplay. While doing so, we provide a review of existing GxE studies on educational outcomes exploiting policy reforms or environments that could be targeted by public policy.

Studies show that psychological effects are among one of the top concerns for public transportation users. While many Americans spend a significant portion of their time in public transportation spaces, the impact of the design and maintenance of these spaces on user well-being has not been fully studied. In this study, we conducted a survey to better understand the effect of implementing different designs on people's well-being and perceptual metrics (N=304). Participants were presented with six images depicting different cabin configurations, including (1) the current version of the cabin space, (2) a low-maintenance version, (3) an aesthetically enhanced version, (4) a bike rack-enabled version, (5) a version with an added workspace, and (6) an improved version with biophilic design. After viewing each image, participants' well-being metrics (e.g., stress, and emotion) and their public transportation perception metrics (e.g., perceptions of safety, and reasonable cost) were evaluated. Our results from linear mixed-effect modeling indicated that adding functional amenities and biophilic design elements led to an overall enhancement in well-being and perceptual metrics. Conversely, low maintenance worsened all measured well-being. This research lays the ground for developing human-centered public transportation spaces that can lead to an increase in public transportation adoption.

This paper establishes an empirical baseline of public sentiment toward Fourth Industrial Revolution (4IR) technologies across six European countries during the period 2006--2019, prior to the widespread adoption of generative AI systems. Employing transformer-based natural language processing models on a corpus of approximately 90,000 tweets and news articles, I document a European public sphere increasingly divided in its assessment of technological change: neutral sentiment declined markedly over the study period as citizens sorted into camps of enthusiasm and concern, a pattern that manifests distinctively across national contexts and technology domains. Approximately 6\% of users inhabit echo chambers characterized by sentiment-aligned networks, with privacy discourse exhibiting the highest susceptibility to such dynamics. These findings provide a methodologically rigorous reference point for evaluating how the introduction of ChatGPT and subsequent generative AI systems has transformed public discourse on automation, employment, and technological change. The results carry implications for policymakers seeking to align technological governance with societal values in an era of rapid AI advancement.

Abstract Background Marriage dissolution, divorce, or separation from a spouse or common-law partner is a serious public health concern due to its increasing prevalence and devastating health and socio-economic consequences. Evidence suggests an increased risk of marital instability in Ethiopia. In addition, the extent of marital dissolution and other related factors have increased in the study area. Despite these, the prevalence of marital dissolution and the influence of associated factors (main reason for marriage, and parental history of marital dissolution) on marital dissolution has not been assessed in the study area. Therefore, the aim of this study was to investigate the prevalence of marital dissolution and its associated factors among residents of Hosanna town in southwestern Ethiopia in 2022. Methods We conducted a community-based cross-sectional study among 459 randomly selected Hosanna Township residents. We used structured questionnaires to collect data. Descriptive statistics and logistic regression were performed to describe the data and test-associated factors, respectively. A p-value less than 0.05 was used to define statistical significance. We used STATA 14 and IBM SPSS 25.0 computer packages to process data. Results Out of the 459 potentially eligible individuals, 450 participants properly responded to the questionnaires yielding a response rate of 98.04%. Of these, 218 (52.9%) were female. The commonly reported reason for marriage was to have children 150 (36.9%). The prevalence rate of marital dissolution was 26.0% (95% CI: (21.7%, 30.3%)). The participant's level of education and the primary reasons (motives) why they get married were statistically significantly associated with marital dissolution. The odds of marital dissolution was higher among participants who completed secondary education (AOR = 3.2, 95% CI = 1.26–8.17) compared to those having no formal education. The participants who married for companionship reasons (AOR = 0.31, 95% CI = 0.11–0.83) had significantly lower odds of marriage dissolution compared with those who married for financial security. Conclusions In this study, the prevalence of marital dissolution was high. The participant’s level of education and the primary reasons (motives) why they getting married were significantly associated with marital dissolution. Therefore, an integrated, community-based approach should be developed to prevent marital dissolution.

Os Juizados Especiais foram instaurados com o propósito de disponibilizar procedimentos céleres, simples e informais, com contornos mais adequados às necessidades dos cidadãos em situação de hipossuficiência econômica, social e informacional. Inobstante, várias das regras aplicadas ao sistema dos juizados não se coadunam com o intuito de ampliação do acesso à justiça, eis que, ao invés articularem um mecanismo eficiente para a tutela de litigantes vulneráveis, dificultam a reivindicação de seus direitos em juízo. Desse modo, com base em revisão bibliográfica e em inferências de caráter predominantemente indutivo, o presente estudo tem por objetivo avaliar a dissonância do discurso que legitimou a instauração dos Juizados Especiais em relação às diretrizes procedimentais consignadas nas leis responsáveis por regulamentá-los. Num primeiro momento, serão revisitados marcos teóricos que exploraram o entrelaçamento do campo do processo civil com a ideologia e a cultura, a fim de demonstrar que o conteúdo do direito processual é fortemente influenciado por forças exteriores ao universo jurídico. Após, proceder-se-á à análise do conteúdo da Lei no 9.099/95, de modo a apontar dispositivos que contradizem a promessa dos Juizados Especiais de tutelar os direitos dos cidadãos hipossuficientes. Na sequência, com base no conceito de seletividade do sociólogo Claus Offe, serão esboçadas possíveis explicações para as contradições havidas entre a aparência e a realidade dos Juizados Especiais, sugerindo-se que, por detrás de sua configuração procedimental, reside o intuito de precarizar o tratamento das “pequenas” causas. Por fim, serão expostas as conclusões alcançadas ao longo da pesquisa.

The purpose of the article is to study the theoretical and legal discourse of the modern definition of the motivational component of the legal protection of public morality in the activity of law enforcement agencies of Ukraine. As a result of the conducted analysis, it is necessary to state that motivational orientation should be interpreted as a category of philosophical praxeology, which is most closely related to the concept of determination, and therefore, taking into account that motivation is an element and axiological, it is appropriate to emphasize the importance of confidence and conviction of a person in the correctness and reasonableness their own aspirations. This is possible provided there is a clear regulatory basis, especially when it comes to protocol and such responsible work as law enforcement. The article establishes that the motivation of a law enforcement officer closely interacts with legal deontology, which, by its very nature, determines the basic moral and social principles of interpersonal relations, which motivate in what way a law enforcement officer should understand his professional purpose, how exactly to interpret his mission, and, at most, to realize why the law enforcement profession exists at all. It was established that when investigating the motivational determination of the legal protection of public morality within law enforcement agencies, it is advisable to, first of all, talk about the implementation of the function of legal protection as a professional duty of representatives of law enforcement agencies, which follows from legal norms. It has been established that the problem of the relationship between public morality and the axiology of law enforcement activity is not only a complex topical question and a complex cognitive process, but, in fact, a new epistemological mechanism of scientific immersion in the ideological social foundations of the era of law enforcement system reforms, the era of revolutionary changes and, unfortunately, military realities of modern Ukraine. It is suggested that the motivational determination of the protection of public morality by law enforcement agencies, or their moral self-regulation, should be interpreted as a very comprehensive process, characterized by external and internal determinants, conditioned by the object of legal protection itself and dependent on the specifics of a specific law enforcement agency and its structural unit.

We construct quantum public-key encryption from one-way functions. In our construction, public keys are quantum, but ciphertexts are classical. Quantum public-key encryption from one-way functions (or weaker primitives such as pseudorandom function-like states) are also proposed in some recent works [Morimae-Yamakawa, eprint:2022/1336; Coladangelo, eprint:2023/282; Barooti-Grilo-Malavolta-Sattath-Vu-Walter, eprint:2023/877]. However, they have a huge drawback: they are secure only when quantum public keys can be transmitted to the sender (who runs the encryption algorithm) without being tampered with by the adversary, which seems to require unsatisfactory physical setup assumptions such as secure quantum channels. Our construction is free from such a drawback: it guarantees the secrecy of the encrypted messages even if we assume only unauthenticated quantum channels. Thus, the encryption is done with adversarially tampered quantum public keys. Our construction is the first quantum public-key encryption that achieves the goal of classical public-key encryption, namely, to establish secure communication over insecure channels, based only on one-way functions. Moreover, we show a generic compiler to upgrade security against chosen plaintext attacks (CPA security) into security against chosen ciphertext attacks (CCA security) only using one-way functions. As a result, we obtain CCA secure quantum public-key encryption based only on one-way functions.

Urban forests provide ecosystem services that are public goods with local (shade) to global (carbon sequestration) benefits and occur on both public and private lands. Thus, incentives for private tree owners to invest in tree care may fall short of those of a public forest manager aiming to optimize ecosystem service benefits for society. The management of a forest pest provides a salient focus area because pests threaten public goods provision and pest management generates feedback that mitigates future risks to forests. We use a game theoretic model to determine optimal pest treatment subsidies for a focal privately owned tree and use an optimization approach to guide targeted public treatment of a representative public tree. We find that optimal public subsidies for private tree treatment depend on assessed tree health and on the prevalence of the pest in the community, considerations absent from many existing programs. Next, by applying our pest treatment policies to a community-scale model of emerald ash borer forest pest dynamics, we predict ash mortality under a range of treatment scenarios over a 50-year time horizon. Our results highlight how designing policies that consider the public goods benefits of private actions can contribute to sustainable land management.

With the beginning of Russia’s large-scale war against Ukraine on February 24, 2022, Ukraine’s economy suffered shock influences, which on the part of the main public administration bodies caused an urgent need to respond promptly to the sharp changes and dynamics of events that have since unfolded. In addition, it was necessary to understand why and for what reasons the financial-economic system of Ukraine reacted in the way it behaved. Thus, the presented study is aimed at defining and assessing the effectiveness of the implementation of the previous systemic policy along with analyzing the operational actions of the National Bank of Ukraine as the main financial-economic regulator in the conditions of belligerency with regard to the country’s economy. Such an analysis provides an opportunity to further adjust the tactics of managing the financial-economic processes, taking into account the identified shortcomings in the implementation of decisions of previous periods. The research uses a comprehensive approach to macroeconomic analysis, methods of structural analysis and analysis of the dynamics of financial-economic indicators in retrospection. The research is built in two stages. At the first stage, with the help of retrospective financial-economic analysis methods, an assessment of the efficiency of the implementation of the defined Strategy for the development of financial markets in Ukraine for the period from 2016 to 2021 was carried out. At the second stage of the research, the actions of the Central bank were recorded, which led to the stabilization of the macroeconomic crisis in the country, the main directions of operational regulation during martial law in Ukraine were determined, their efficiency was assessed. A retrospective analysis of the actions of the National Bank of Ukraine in 2016-2022 showed that during this period the following important results were achieved in ensuring both financial and price stability, also the stability of the monetary unit: the monetary regime was used quite successfully in conducting inflation targeting, the standards of commercial banks were increased, a program for the accumulation of international reserves was carried out, and the exchange rate was regulated in order to ensure its growing. The assessment of the actions of the National Bank of Ukraine during the period of martial law after February 24, 2022 showed that the following measures of operational regulation were carried out: a number of external and internal incoming and outgoing financial barriers were applied, the accounting rate was regulated, special measures were constantly taken to ensure the financial-economic reserves of the financial system of Ukraine, new mechanisms of financial levers for the credit situation were developed. Further on, it would be advisable to consider the efficiency of regulating the financial-economic situation in a more distant period in order to be able to assess the correctness and fallacy of the decisions taken and adjust the regulator’s actions to maintain a stable state of the economy and further gradually exit from the crisis status. This analysis allows society to apprehend the complexity, consistency of actions of the central economic regulatory bodies, to understand the consequences and expediency of such actions. The presented research is original and comprehensive, touching on all macroeconomic aspects of the activities of the main financial regulator of Ukraine, its influence on the financial-economic situation of the country.

BACKGROUND: Severe asthma mandates careful attention and timely management, and the benefit of ketamine in severe asthma exacerbations in adult patients require further exploration. METHODS: We conducted a systematic review and meta-analysis of the use of ketamine in cases of acute asthma exacerbation in adults. We searched PubMed, Google Scholar, Cochrane databases, and gray literature (ClinicalTrials.gov and World Health Organization International Clinical Trials Registry Platform); we also searched the reference lists of included articles and any systematic reviews and meta-analyses identified therein. Our search covered the period from 1963 to August 20, 2021. Search terms were “ketamine” AND “asthma”. RESULTS: Of 25 540 articles, two studies were included in the analysis. The total number of patients included in the studies was 136 (68 in the ketamine groups and 68 in the placebo group). The pooled effect size was 0.30 (95% CI: -0.04, 0.63) favouring ketamine over placebo, p=0.08, (I2=0%, p=0.39). A paired t-test revealed that ketamine improved the mean peak expiratory flow rate (PEFR) from 242.4 (SD=146.23) to 286.95 (SD=182.22), p=0.33, representing an 18.38% improvement. CONCLUSION: Ketamine can induce a 30% improvement in PEFR, representing a small positive effect in the treatment of acute severe asthma exacerbation in the emergency department (ED). The improvement was not statistically significant; nonetheless, since the improvement could be as great as 63% versus only a 4% possibility of no benefit/harm, the benefit appears to considerably outweigh any harm.
