We live in turbulent times. Humanity has become a geological force altering planetary conditions whilst notions of a universal abstract human have been challenged by the geohistorical formation of ecologies of power, capital and nature. Climate change, along with conceptualisations of education rooted in industrial framings of the world centring on human progress, testifies to multiple crises. This contribution attends to the connectedness of multiple crises and the complexity needed to address them by probing their marks, what is introduced as the etchings of metacrisis. In so doing, climate change and education are brought together to problematise the mindset of modernity and Enlightenment and the transhistorical continuity of -isms violences (capitalism, colonialism, imperialism, industrialism). Transoceanic thinking and Édouard Glissant’s notion of whirling encounters are mobilised along an affective approach to archives re-imagining environmental education. Such an approach prompts imaginaries of eco-relationality traversing the local and the global, the past and the present and re-vivifying the relationality of peoples and Land without downplaying violences of the -isms.

A general asymptotic theory is established for sample cross moments of nonstationary time series, allowing for long-range dependence and local unit roots. The theory provides a substantial extension of earlier results on nonparametric regression that include near-cointegrated nonparametric regression as well as spurious nonparametric regression. Many new models are covered by the limit theory, among which are functional coefficient regressions in which both regressors and the functional covariate are nonstationary. Simulations show finite sample performance matching well with the asymptotic theory and having broad relevance to applications, while revealing how dual nonstationarity in regressors and covariates raises sensitivity to bandwidth choice and the impact of dimensionality in nonparametric regression. An empirical example is provided involving climate data regression to assess Earth’s climate sensitivity to CO$_2$, where nonstationarity is a prominent feature of both the regressors and covariates in the model. To our knowledge, this application is the first nonparametric empirical analysis to assess potential nonlinear impacts of CO$_2$ on Earth’s climate while allowing for nonstationarity in both the regressors and covariates.

Lepidopteran stemborers are among the most destructive pests of maize, sorghum, and sugarcane in Africa. Yet, data on their species composition and host range in Rwanda remain limited. This study provides the first comprehensive assessment of stemborer diversity, seasonal dynamics, and altitudinal distribution across eastern (low altitude), central (mid-altitude), and northern (high altitude) Rwanda. Surveys were conducted during both the rainy (maize growing) and dry seasons of 2023–2024, targeting infested maize fields and surrounding wild vegetation. A total of 2691 stemborer individuals were recovered from nine host plants, with 1474 (54.8%) from wild and fodder vegetation and 1217 (45.2%) from maize plantations. Species richness was highest in the mid-altitude zone, while overall abundance peaked at low altitudes. Busseola fusca was the most abundant in the high-altitude zone, Chilo partellus in the low altitude, and Sesamia spp. was concentrated in the mid-altitude. Seasonal variation significantly influenced population dynamic, with the highest abundance (1251; 46.4%) recorded during the dry season. Notably, Pennisetum purpureum (Napier grass) hosted 1156 (42.9%) of all specimens, highlighting its role as a key refugium during maize off-seasons. These findings underscore the ecological importance of wild vegetation in sustaining stemborer populations and suggest that wild vegetation, altitudinal, and seasonal factors must be considered in designing integrated lepidopteran stemborer pest management strategies.

In a series of detective novels published between 1957 and 1969 Chester Himes portrayed diverse individuals struggling for survival, wealth, and status in a fictionalized postwar Harlem, combining what Richard Wright called a “bio-social” perspective with an antiracist aesthetics that falsified simplistic racial categories. In this essay, I trace Himes’s renderings of bodily difference and transformation, highlighting features neglected by contemporaries such as Ellison and Baldwin as well as more recent critics and readers who frame Himes’s writings as protests against anti-Black violence. I conclude that Himes’s Harlem novels did not simply reflect violent realities of African American lives but instead exhibited unresolved conflicts between antiracist imperatives, namely a recognition of individual complexities on the one hand, and organized struggle against racially discriminatory institutions and practices on the other.

In alignment with the vision for the future of the European Union (EU) put forth by the European Green Deal in 2020, and EU efforts to tackle global deforestation and forest degradation, the EU Deforestation-Free Products Regulation (EUDR) was adopted in June 2023. The EUDR is designed specifically as a unilateral, yet transnational, intervention to limit access to the EU market or the exports from the EU of seven key forest-risk commodities whenever they are linked with deforestation, forest degradation, or illegality. Drawing on decolonial and critical food systems scholarship, this article critically examines the EU’s position in combating global deforestation and forest degradation by positioning the EUDR in historically shaped and unequally constructed agri-food chains. Whereas the EU’s plan to decrease deforestation and forest degradation linked with its substantive consumption of products from the global south is an innovative step from the point of view of transnational governance of environmental degradation, we find that the historical amnesia, the emphasis on global trade, and the push for ‘green value chains’ fail to address the root causes of deforestation. Moreover, we contend that the EU legislator overlooked the potential of using transnational governance to rethink agri-food systems, including by promoting re-regionalization in the name of food sovereignty and the right to food.

In The Spirit of the Laws, Montesquieu announces that he would be the happiest of mortals if he could help men cure themselves of their prejudices. Though he demands that we understand prejudice’s role in his work, scholars have not excavated his whole strategy regarding it. Preliminary investigations have concluded that he sought to destroy prejudices because he had a high estimation of popular reason. This article argues that, while he does seek to eliminate prejudices that support despotism, he also encourages salutary ones for liberty. His whole strategy regarding prejudices shows that his use of them reflects a modest assessment of reason. By demonstrating that two of his well-known strategies for political reform—reinterpreting Christianity and encouraging commerce—concern salutary prejudices, this article reveals the centrality of prejudices to his political project overall.

The RNCP/NIAID recommends the creation of a North American Biodosimetry Assessment Networking Group (BANG) by developing a blueprint for integrating the relevant national capabilities to provide emergency biodosimetry assistance in civilian populations following a radiological or nuclear incident. The goals of BANG are to: 1) establish a collaborative network (public/private partnership) and engage its membership to address emergency preparedness, response, and recovery, 2) promote strategic relationships between network members to encourage resource sharing, 3) engage with stakeholders to utilize recommended tools and support training exercises, and 4) advance bioinformatics and machine learning approaches to integrate and utilize the network data for managing emergency situations.

To be adequately prepared for large-scale radiological or nuclear incidents, a coordinated network among well-trained, commercial, hospital, and/or academic laboratories is a critical factor for providing rapid exposure assessments. Interactive and productive collaborations between North American laboratories will improve the capabilities of the network by offering a wider range of complementary biological and physical techniques. BANG would connect community service providers with various biodosimetry capabilities, and enable members to discuss best practices, common goals, emergency planning/ training, and sharing of resources, to increase the nation’s resiliency before, during, and after a radiological public health emergency.

This paper presents a wideband dual-polarized microstrip patch antenna with a dual-layer design to meet the requirements of high isolation for in-band full-duplex (IBFD) communication systems. The antenna improves upon the traditional square patch with four Γ-shaped probe-fed by ingeniously extending the metal strips of the Γ-shaped probes to form a cross-shaped structure, thereby exciting multiple independently tunable resonant modes. A circular ring slot is etched at the feed point to optimize the antenna impedance matching. Finally, a middle-layer circular patch is added to optimize the high-frequency impedance matching without changing the profile. By combining differential feeding technology, the antenna maintains a low-profile characteristic of 0.086λL (where λL denotes the free-space wavelength at the lowest operating frequency) while achieving dual-polarized operation and high port isolation (≥42 dB), along with an impedance bandwidth of 71.5% (4.06–8.58 GHz) that surpasses most existing designs. The measured antenna realized peak gain is 8.2 dBi, with cross-polarization suppression ≤−20 dB and stable radiation pattern characteristics across the operating frequency band. This design provides a compact antenna solution with high isolation, broadband, dual polarization, and low cost for IBFD applications.
