Currently, China boasts abundant shale gas resources. However, in the process of flowing production, there remain significant discrepancies in our understanding of the flow patterns of gas and water, and many challenges persist in gas–water measurement. Given the dense pore structure and complex micro-features of shale gas reservoirs, this study proposes a method to estimate the fractal dimension by utilizing shale mercury injection curves based on experimentally determined relative permeability curves, thereby enabling a more accurate fitting of these curves. Experimental results show that the two-phase co-infiltration zone in the shale is narrow overall, with bound water saturation exceeding 50%. The findings indicate that the experimentally measured relative permeability curves closely match those fitted using the fractal dimension approach. Moreover, the lower the permeability, the more the equal-permeability points of the fitted curves shift toward the lower-right quadrant. Overall, the fitting performance is satisfactory, providing additional research directions and insights for determining relative permeability curves of gas and water in shale gas reservoirs.

A translative covering the rectangle $a\times b$ with homothetic copies of a right isosceles triangle T (of the legs parallel to the sides of $a\times b$) is considered. It is shown that any collection of equal triangles homothetic to T with the total area at least 2 permits a translative covering of $1\times 1$; this bound is tight. It is also demonstrated that any collection of positive homothetic copies of T with the total area at least 3 permits a translative covering of $1\times 1$. Moreover, it is proven that if $a\ge {\displaystyle \frac{5+\sqrt{33}}{4}}b$, then any collection of triangles homothetic to T with the total area at least ${\displaystyle \frac{1}{2}}{(a+b)}^2$ permits a translative covering of $a\times b$; this bound is tight.

Over the past decade, far-right parties have moved from the political margins into the mainstream of several European democracies. This article examines how migration functions not primarily as a demographic driver of electoral change, but as a discursive resource through which democratic boundaries are redefined. Drawing on a qualitative comparative analysis of political speeches, party manifestos, and public debates in selected European countries between 2014 and 2022, the study investigates how migration is constructed as a threat to welfare systems, national cohesion, and liberal-democratic order. The analysis integrates three complementary frameworks of ethno-pluralism, welfare chauvinism, and civic nationalism to demonstrate how exclusion is legitimized through moralized appeals to culture, fairness, and liberal values. Rather than rejecting democracy outright, far-right actors reinterpret concepts such as citizenship, solidarity, and equality in conditional and culturally bounded terms. Migration thus operates as a symbolic condensation of broader anxieties related to globalization, economic insecurity, and political distrust. The findings show how democratic language itself can normalize exclusionary interpretations of membership, contributing to gradual forms of democratic erosion across Europe. Full article

Highway–rail grade crossing (HRGC) safety research relies on federal incident and inventory datasets that span multiple decades. However, inconsistencies in geographic identifiers and incomplete reconstruction of crossing denominators can distort exposure-based rate metrics. This study develops, documents, and validates a transparent nine-stage reconciliation pipeline applied to 51 years (1975–2025) of national HRGC incident data from the Federal Railroad Administration Form 57 and Form 71 datasets. The hierarchical pipeline integrated deterministic alignment and multistage inference methods to produce an audited, geographically consistent dataset. The study formalizes four longitudinal county-level cumulative exposure indices that characterize spatiotemporal patterns of incident concentration relative to static population and infrastructure denominators. These metrics include accumulated incidents per million population (AIPM), accumulated incidents per crossing (AIPC), crossings per million population (CPM), and crossings per 100 square miles (CPHSM). All four metrics exhibited pronounced right-skewness: AIPM, CPM, and CPHSM approximated exponential forms, and AIPC approximated a log-normal form. Statistical tests detected statistically significant tail deviations in three metrics; CPM did not reject the exponential fit at conventional significance levels. Spatial analysis shows coherent regional concentration in incident rates in the Central Plains and lower Mississippi corridors. The national time series exhibits a late-1970s plateau, sustained exponential decline beginning around 1980, and stabilization but persistent incident rates after 2001. Population-normalized AIPM remained statistically indistinguishable between the reconciled and record-dropped datasets; however, crossing-based metrics changed materially when reconstructing denominators from the reconciled crossing universe. Statistical comparisons confirmed that incident-only denominators introduced substantial measurement bias in local risk assessment. State-level rank reversals persisted even when omnibus distributional tests failed to reject equality. By formalizing multistage data cleaning and quantifying its analytical impact over an unprecedented longitudinal horizon, this study establishes denominator integrity and geographic reconciliation as prerequisites for valid HRGC exposure assessment and provides a framework for future predictive modeling.

This conceptual article examines how special education in Greece is governed through the redistribution of institutional responsibility to families. It operationalises familialisation by specifying institutionally produced parental roles through which provision is organised under fragmented and contingent conditions. By tracing how these roles relate and shift across placement arrangements (e.g., parallel support, inclusion units, special assistants, home-based instruction, segregated schools), the article argues that parental labour can be understood as a structural condition shaping access to mainstream placement and support. It concludes that familialised governance converts formally equal rights within public education into unequal possibilities of realisation by making mainstream participation dependent on households’ differential resources and institutional capacity.

This article discusses the link between secularisation and the rights of religious and belief minorities. Using data from the Atlas of Religious or Belief Minority Rights, it measures the extent to which RBM rights are respected, promoted and restricted. Taking the number of ‘nones’ in a country as an indicator of the secularisation of its legal system, it examines the impact of secularisation on the promotion of religious minority rights and the equal treatment of minorities, as well as the gap between their rights and those of the majority. The article concludes that secularisation does not directly promote RBM rights. Instead, it reduces the disparity between the rights enjoyed by the various minorities and between them and the majority Church. Notably, there is a clear correlation between secularisation and the majority–minority rights gap: highly secularised states tend to reduce it, whereas less secularised states tend to widen it. In terms of equal treatment, a highly secularised state does not guarantee equal treatment of all RBMs. However, a less secularised state makes equal treatment even more difficult. Full article

Gender-based violence in public transportation is a global phenomenon that restricts women’s rights and autonomy. Most of the documentation relies on harassment and physical aggression, but the subtle internalized mechanisms that reproduce gender inequities remain insufficiently analyzed. This study involves the concept of symbolic violence as an analytical category to unveil how resignation and normalization of violence perpetuate gender power relations and limit women’s mobility. A cross-sectional survey of 263 women aged 15–60 was conducted in Querétaro, Mexico, a rapidly growing city with significant mobility challenges. The questionnaire included items on perceptions of safety, violent experiences, responses to acts of violence, and prevention strategies. An inductive–abductive analysis was implemented to construct empirical indicators derived from Bordieu’s concept of symbolic violence and habitus. Findings reveal that fear, avoidance, and self-regulation are normalized responses to violence in public transport. Women implement strategies such as changing routes, limiting night travel, or increasing their expenses to access safer options. Six empirical indicators were identified: perceived insecurity as normality, resignation to harassment, bodily and emotional self-regulation, preventive reorganization of mobility, personal costs of safety, and collective inaction. In conclusion, the study demonstrates how symbolic violence operates through behaviors, actions, perceptions, and thoughts that reproduce inequities. Operationalizing symbolic violence provides a methodological and conceptual tool to advance gender equality and inform gender-sensitive mobility policies. Full article

Sudden cardiac death (SCD) is a major global health issue, defined as sudden natural death presumed to be of cardiac cause. While in the elderly SCD is commonly associated with coronary artery disease, in the younger population it is linked to inherited cardiomyopathies or channelopathies, even though SCD can remain unexplained even after a comprehensive autopsy in a substantial proportion of cases. In this context, genetic testing has gained importance, supported by the widespread availability of techniques such as next-generation and whole-exome/genome sequencing and their reduced costs. This state-of-the-art review summarizes the genetic bases of sudden cardiac death among cardiomyopathies, channelopathies and in sudden unexplained death presumed to be of arrhythmic cause. Among the structural causes, inherited cardiomyopathies such as hypertrophic, dilated, non-dilated left ventricular, arrhythmogenic right ventricular and restrictive ones represent major substrates for malignant ventricular arrhythmias mostly arising from variants in sarcomeric or desmosomal genes. Channelopathies (long or short QT syndrome, Brugada syndrome and catecholaminergic polymorphic ventricular tachycardia) are caused by variants in genes encoding cardiac ion channels and/or regulatory proteins, which equally predispose to high risk of life-threatening ventricular arrhythmias. In sudden arrhythmic death syndrome, with a structurally normal heart, post-mortem genetic testing (molecular autopsy) can uncover an underlying inherited condition. However, variants of uncertain significance are detected in more than half of the cases, underscoring the need for a multidisciplinary approach. Genetic testing also plays a key role in cascade screening of first-degree relatives. While monogenic variants drive risk in inherited cardiac disorders, emerging evidence suggests that polygenic contributions may modulate SCD susceptibility, highlighting future roles for polygenic risk scores in risk stratification.

Background: Limitations in timely and equitable access to essential medicines among older adults not only constitute a clinical barrier to the effective management of chronic conditions, but also represent a violation of the fundamental right to life, health and the principles of dignity, equality and non-discrimination that safeguard this population within the framework of human rights. Objective: To examine access to essential medicines for older adults with high-cost chronic conditions as a constitutive dimension of the fundamental rights to health, life and human dignity, in accordance with international human rights standards. Design: A literature review was conducted of articles published between 2020 and March 2025 in five databases, using the search terms: “pharmacological treatment,” “access to health,” “chronic diseases,” and “barriers to access.” After evaluating the inclusion criteria (language and year) and exclusion criteria (case studies), 12 articles were selected. A narrative synthesis was performed on the following aspects: application of the principles of the right to health, barriers to access, and rights violated or at risk. Results: The expansion of health coverage faces several barriers that violate fundamental principles of the right to health: equity, accessibility to medical advances, and long-term, quality, and specialized services, thus limiting autonomy. In conclusion, guaranteeing access to pharmacological treatments in old age will contribute to building more just and humane societies through public policies on coverage and pharmaceutical education, the simplification of treatment regimens, and the implementation of programs that allow people to age with dignity, considering health a human right based on equality and non-discrimination, participation and transparency.

Women’s political participation and representation is an important requirement for gender equality and achieving a truly democratic society. As provided in the Universal Declaration of Human Rights, women and men have an equal right to civic and political rights. When women are involved in politics, communities move towards gender equality, which ensures that various voices are heard in governance and policy-making. This study was rooted in the fact that many African women continue to face repression, with several societies constraining their capability to contribute fully within political and social domains. The study employed secondary quantitative data to achieve its objective. Panel data for 17 countries with a poor track record on women’s rights and ever-declining rates on the Women’s Development Index were used by the study. A Generalized Method of Moments (GMM) panel technique was used for estimation purposes. The results showed that economic growth, participatory democracy, freedom of expression, globalisation and clean elections have a positive relationship with women’s political participation. This entails that these factors contribute to more political participation for women. The study recommends that in order to enhance women’s political participation, governments and civil society should strengthen by institutionalising inclusive decision-making processes at all levels.

Introduction: Gender-based violence and femicide represent the most extreme manifestation of a deep-rooted cultural distortion embedded within patriarchal social structures. In this study, adopting a comparative and multidisciplinary approach, we analyzed the evolution of international legislation and the major historical milestones in the protection of women’s rights and the prevention of gender-based violence at both the global and Italian levels. Specific protocols such as the “Pink code” were examined, with particular attention to medico-legal implications and the clinical management of victims, highlighting how violence against women continues to be fuelled by stereotypes, discrimination, and unequal power relations. Materials and Methods: Gender-based violence and femicide were examined from both national and international perspectives. A total of 73 scientific articles in English and 28 legal sources were selected from an initial pool of 918 publications, through a narrative review with a structured search strategy of international and Italian legislation and scientific literature. Electronic databases (PubMed and Google Scholar) were searched for the period 2000–2025. Only original observational studies, medico-legal analyses, epidemiological reports, and forensic case series were included. Cases primarily related to pregnancy, migration, infanticide, suicide, or substance abuse were excluded to reduce heterogeneity and focus on violence rooted in gender-based power asymmetries. Results: The legislative analysis shows a progressive strengthening of protection mechanisms, particularly between 2012 and 2023, following the ratification of the Istanbul Convention, the increase in intimate partner violence, and the COVID-19 pandemic. In Italy, the repeal of discriminatory norms and the introduction of specific legislative measures have led to increased attention toward prevention, protection, and prosecution of gender-based violence. Protocols such as the ‘Pink Code’, an Italian hospital-based multidisciplinary pathway activated mainly in emergency departments for the early identification, clinical care, medico-legal documentation, and judicial protection of victims of gender-based violence, have improved multidisciplinary management of victims within healthcare and judicial settings, although significant challenges remain regarding the full enforcement of legislation and the effective protection of women. The analysis focuses on female victims, in accordance with the Italian legal definition of gender-based violence, while other forms of gender-related violence were considered beyond the scope of this review. Conclusions: Despite substantial legal advances, combating gender-based violence clearly requires an integrated approach that combines prevention, assistance, and prosecution. Strengthening collaboration among institutions, healthcare services, and the judicial system—consistent with international recommendations—is essential to ensure an effective and rights-based response to victims. Overcoming the cultural and social barriers that perpetuate violence remains a fundamental priority, alongside promoting genuine gender equality. Full article

The phenomenon of immigration, together with an increasingly interconnected form of globalization and the rapid development of scientific and digital technologies, has placed considerable pressure on contemporary Western constitutional orders. These dynamics have compelled States to confront complex challenges, particularly with respect to facts, rights, and freedoms relating to religion. While such trends are observable in numerous countries, this article focuses on Italy, which is particularly instructive in terms of its approach to contemporary cultural–religious pluralism. From this perspective, the Italian legal framework exhibits several distinctive features, most notably in the regulatory arrangements based on accordi (agreements) and intese (understandings) concluded between the State and religious denominations pursuant to Articles 7 and 8(3) of the 1948 Constitution.

Although Palestine ratified the Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) in 2014 without reservations, women’s labour-force participation has remained largely stagnant over the past fifteen years, fluctuating between 16% and 20%, raising critical questions about the operational effectiveness of international gender-equality commitments. Focusing on Article 11 of CEDAW, this study adopts a mixed-methods design that integrates administrative labour-force statistics, a survey of 529 economically active women, and qualitative evidence from key-informant interviews, legal texts, and policy documents. Quantitative findings reveal a systematic divergence between symbolic awareness of CEDAW and actionable knowledge of Article 11, with substantially higher levels of informed awareness among respondents engaged through authoritative institutional or civil-society channels. Qualitative evidence further demonstrates that labour-market reforms associated with Article 11 have been uneven and selective, constrained by weak enforcement capacity, fragmented institutional coordination, and employer cost-avoidance practices, particularly in the private sector. Taken together, the findings indicate that CEDAW ratification in Palestine has functioned primarily as a normative anchor rather than as an operational driver of labour-market transformation. By situating these findings within the Sustainable Development Goals framework, the study contributes to SDG 5 (Gender Equality) and SDG 8 (Decent Work) by demonstrating how rights awareness and enforcement credibility condition women’s employment outcomes, while highlighting the central role of institutional coordination and civil-society mediation in line with SDG 17. The study advances debates on treaty implementation by showing that, in fragile governance contexts, progress toward gender-equality targets depends less on formal legal adoption and more on the institutional pathways through which rights are translated into practice.

This paper explores the controversial issue of the extent to which human rights values are universal and applicable within all cultural contexts across the contemporary world. It evaluates three claims that are commonly made by those working in the field of intercultural education: (i) because human rights are a product of Western ways of thinking, they are incompatible with the values and norms of non-Western cultures; (ii) applying human rights to non-Western cultures is culturally insensitive and a form of cultural imperialism; and (iii) human rights are based on an individualistic conception of the human being and are therefore inappropriate for collectivistic cultures. This paper provides a critical review of all three claims, with the aim of evaluating each of them in turn. The review reveals that the claim that human rights are incompatible with the values and norms of non-Western cultures is both factually incorrect and analytically problematic; that historically, the contents of the Universal Declaration of Human Rights were shaped and endorsed by both Western and non-Western actors; and that human rights are based on a collectivistic and communitarian—not an individualistic—conception of the human being. It is argued that the approach to human rights that is compatible with these conclusions is relative universalism, according to which the implementation of human rights principles should always display flexibility so that cultural specificities can be appropriately balanced against the general principles of universal human rights. Two further issues that are also discussed are the organised hypocrisy in the policies of many Western governments in relationship to human rights and the need for greater material equality to ensure the effective implementation of human rights. The conclusion that is drawn from the review is that there is no ethical dilemma for those working in the field of intercultural education in embracing and endorsing universal human rights, that a culturally sensitive approach can, and indeed should, be adopted in applying universal human rights principles in all cultural contexts, and that the assault on universal human rights from intercultural education is based on widely repeated misunderstandings and myths about human rights.

In this article we highlight and discuss how norm-challenging pedagogy in music education can be encouraged and executed from three different angles. We primarily focus on activities such as democratic learning situations for pupils and teachers, to be explored as safe and brave spaces. With a starting point in norm-critical pedagogy, we explore the possibility of using norm-challenging pedagogy as, through and in music educational settings. Norm-challenging pedagogy as music education can challenge dominant ways of assimilating, processing, and expressing knowledge, whereas norm-challenging pedagogy through music education concerns how traditional views on, for example, gender, race, or disability identities can be challenged through music activities. Norm-challenging pedagogy in music education critically reflects on who has the right to learn and express themselves musically and in what ways, related to gender, race or disability. The article is based on a phenomenological view of aesthetic experience and music education as a life of equal value, where de Beauvoir’s concepts of freedom, facticity, and ambiguity constitute crucial analytical concepts. The author’s own experiences of ambiguous norm-challenging situations as, through and in music education will be used and discussed in relation to the philosophical framework. The results of the exploration will be critically reflected upon in relation to organisational, collegial, didactic and relational aspects of music education. Full article
