Ruth Glacier is situated in the Central Alaska Range, with the Don Sheldon Amphitheater comprising much of its broad accumulation area, directly adjacent to North America's tallest mountain, Denali. From there it funnels through the ‘Great Gorge,’ flanked by steep valley walls reaching over 1500 m. We combine airborne and ground-based radar measurements of ice thickness with satellite-derived surface velocities to constrain ice flux above and below the gorge, and employ a mass conservation approach to estimate the glacier's thickness within the gorge. We measure ice thickness in the amphitheater to reach 950 m, and estimate centerline thickness in the gorge to range from 610 to 960 m. Our estimates are up to two times greater than those suggested by global models, and allow us to confirm that the Great Gorge rivals Hells Canyon as the deepest gorge in North America. We found that the geometry of the gorge prevents radar measurements of ice thickness there since returns from the subglacial valley walls would precede and potentially occlude nadir bed returns. The same may be true of other unmapped mountain glaciers; however, thickness may be determined using appropriately located flux gates where radar sounding is feasible, combined with mass conservation methods.

This article develops an account of territorial justice to understand what is owed to people at risk of climate displacement. I argue that the aim of territorial justice is to secure a globally recognized status, the status of being an equal common possessor of the earth. As a common possessor, every inhabitant of the globe has a claim to a “place” in the world where they can access minimally just material conditions and political institutions, securely pursue their located practices, and exercise self-determination together with others. I apply this theory to generate prescriptions for a just policy response to the risk of climate displacement. Where possible, I argue that a just response should focus on mandatory global taxation to support in situ adaptation. In cases where relocation becomes inevitable, I outline the implications for how just relocation regime should be structured.

This article focuses on the discussions around female athletes and their emotions in the German and Austrian press of the 1920s. In the course of the sports boom of the interwar years, more and more women participated in public sports competitions and demanded their right to be taken seriously as sportswomen. Their public appearance aroused mixed feelings and heated social debates about how much and what kind of sport was appropriate for women, which were reflected in discussions and narratives around the figure of the “sportsgirl.” Sportsgirls were imbued with a novel emotional style to which ambition and audacity – ways of feeling that were cultivated during competitive sports and that contrasted with traditional bourgeois female feeling rules – were key. Sportsgirls and their emotional style were the subject of many stories, reports, pictures, and articles that were published in the growing sports press of the time – and they were judged and evaluated for the emotional style they embodied. The press was a potent platform and site of the formation of feeling rules; as such, discussions around sportsgirls point to the (embodied) experiences of the athletes and indicate how the emotional style that derived from them was turned into a tool to reshape social conventions and feeling rules for women beyond the sports arena.

Isoproturon phytotoxicity to wheat (Triticum aestivum L.) is a worry for many farmers in chemical control of weeds in wheat fields, especially in subzero weather conditions. Iron chlorin e6 (ICe6), a new plant growth regulator, has been reported to enhance crop stress resistance to alleviate damage caused by stress; however, it is not clear whether ICe6 has an alleviative effect on isoproturon phytotoxicity to wheat. We determined the alleviative effect of ICe6 on isoproturon phytotoxicity to wheat, and 0.018 g ai ha−1 was the optimal dose. Meanwhile, we also studied the photosynthetic pigment content, photosynthetic parameters, oxidative stress indicators, and antioxidant enzyme activity of wheat treated with the three different treatments. We found that the photosynthetic pigment content, antioxidant enzyme activity, and photosynthesis of wheat damaged by isoproturon were significantly lower than those of the control, and the hydrogen peroxide (H2O2) and malondialdehyde (MDA) content increased. These results indicate that isoproturon stress significantly weakened the photosynthetic and antioxidant capacity of wheat. The photosynthetic pigment content, photosynthetic parameters (excluding intercellular CO2 concentration), and antioxidant enzyme activity of isoproturon+ICe6– treated wheat were significantly higher than those of isoproturon-treated wheat. The H2O2 and MDA content was significantly lower than that of isoproturon-treated wheat. These results indicate that ICe6 treatment maintained the photosynthetic pigment content of wheat and relatively improved photosynthetic capacity, allowing photosynthesis to proceed normally. ICe6 treatment also limits the decrease in antioxidant enzyme activity, effectively clearing excess reactive oxygen species and ultimately alleviating membrane lipid peroxidation damage. In summary, ICe6 not only enhances stress resistance and increases yield in crops such as soybean [Glycine max (L.) Merr.] and canola (Brassica napus L.), but also has an alleviating effect on the isoproturon phytotoxicity to wheat, which is manifested by the improvement of photosynthetic and antioxidant abilities, ultimately leading to an increase in wheat shoot height and shoot fresh weight.

Irregular migrants’ flows have, for several years now, been making the news headlines and are at the core of political debates. In a context of polycrisis—characterized by the post COVID-19 pandemic, climate change and its devastating impacts; the disruption of labor markets caused by the fourth industrial revolution and artificial intelligence; or geopolitical tensions in different parts of the globe that threaten the livelihoods of many communities—the desire to move from the developing and emerging world to the West can increase.

Adolescents with severe cardiogenic shock can present to both paediatric and adult centres. We present six adolescent children who had extracorporeal membrane oxygenation consultation fast-tracked with clinical care input from the adult multidisciplinary team, including interhospital transfers on extracorporeal membrane oxygenation. After recovery on conventional cardiogenic shock care or extracorporeal membrane oxygenation, or bridge to transplant, all had favourable neurologic outcome.

The transition from childhood to adolescence presents elevated risks for the onset of psychopathology in youth. Given the multilayered nature of development, the present study leverages the longitudinal, population-based Adolescent Brain Cognitive Development Study to derive ecologically informed risk/resilience profiles based on multilevel influences (e.g., neighborhood and family socioeconomic resources, parenting, school characteristics) and their transition pathways and examine their associations with psychopathology. Latent profile analysis characterized risk/resilience profiles at each time point (i.e., baseline, Year-1, Year-2); latent transition analysis estimated the most likely transition pathway for each individual. Analysis of covariance was used to examine associations between profile membership at baseline (i.e., ages 9–11) and psychopathology, both concurrently and at Year-2 follow-up. Further, we examined the associations between profile transition pathways and Year-2 psychopathology. Four distinct profiles emerged across time – High-SES High-Protective, High-SES Low-Protective, Low-SES High-Family-Risk, and Low-SES High-Protective. Despite reasonably high stability, significant transition over time among profiles was detected. Profile membership at baseline significantly correlated with concurrent psychopathology and predicted psychopathology 2 years later. Additionally, profile transition pathways significantly predicted Year-2 psychopathology, exemplifying equifinality and multifinality. Characterizing and tracing shifts in ecologically informed risk/resilience influences, our findings have the potential to inform more precise intervention efforts in youth.

This paper discusses competing visions of the decolonization of Ghana’s economy during the first decade of the country’s independence from Britain (1957–1966), and the agency and horizon of choice available to the Ghanaian decision-makers in charge of implementing these visions. It focuses on Ghana’s construction industry, both as an important part of the national economy and as a condition for Ghana’s broader social and economic development in the context of colonial-era path-dependencies and Cold War competition. By taking the vantage point of mid-level administrators and professionals, the paper shows how they negotiated British and Soviet technological offers of construction materials, machinery, and design. In response to Soviet claims about the adaptability of their construction resources to Ghana’s local conditions, the practice of adaptation became for Ghanaian architects and administrators an opportunity to reflect on the needs, means, and objectives of Ghana’s construction industry, and on broader visions of Ghana’s economic and social development. Beyond the specific focus on the construction industry, this paper conceptualizes the centrality of adaptation in enforcing technological hegemony during the period of decolonization, and discusses African agency beyond the registers of extraction and resistance that have dominated scholarship on the global Cold War.

Peanut (Arachis hypogaea L.) and maize (Zea mays L.) are essential crops for Ghana’s economy and food security, but weed infestation poses a significant threat to their cultivation. Crop rotations influence weed communities, but little is known about these processes in peanut-cropping systems in West Africa. This study investigated the impact of different crop rotations and input levels on weed communities in Ghana over 3 yr. Results showed that low inputs (absence of herbicide and fertilization) favored species richness, while higher input levels (weed control with herbicides and fertilizer use) reduced it. Diversity and evenness were also affected by inputs, with varying patterns across locations and seasons. Weed population growth rates (λ) varied significantly by location and treatment; all management programs resulted in increasing weed populations. Principal component analysis revealed distinct associations between weed species and crop management. The majority of weed species exhibited a generalist behavior and did not associate with a particular management. However, billygoat weed (Ageratum conyzoides L.) and Benghal dayflower (Commelina benghalensis L.) were positively associated with high-input systems, while purple nutsedge (Cyperus rotundus L.) exhibited strong associations with low and medium inputs. The weed–crop rotation dynamics described here demonstrate how management drives the selection of weed species that are more pervasive and interfere with important food crops in Ghanaian agriculture.

This article examines two major recent CCTV documentaries on the Third Front and its afterlives. The Big Third Front (2017) and Vicissitudes of the Third Front (2016) construct strong narratives about the Third Front during the Mao era, depicting it as a heroic struggle against nature which was forced upon China by foreign enemies. However, both documentaries encounter difficulties in adhering to the usual presentation of the Deng era as a resoundingly successful transformation. Vicissitudes ambivalently characterizes the Deng era as one of relative decline in contrast to the glorious early years of the Third Front and the flourishing present. The Big Third Front, meanwhile, conflates historical footage of the 1950s–1990s in a way that undermines the usual official division of PRC history into Mao and reform eras. This paper concludes by suggesting that academic focus on the Third Front can serve as a methodological tool for complicating the periodization of PRC history.

The camber morphing of an aerofoil in ground effect was investigated using the FishBAC method and Detached Eddy Simulations with the k-omega SST turbulence model at a Reynolds number of 320,000. The aerofoil was periodically morphed at a start location of 25% chord from the leading edge with a trailing edge deflection range of 0.1% to 3% and morphing frequencies between a Strouhal number of 0.45 to 4 at a constant ground clearance of 10%. Periodically morphing the aerofoil using a sinusoidal function showed that lift and drag increased on the downstroke and decreased on the upstroke in the cycle, resulting in periodic values of lift and drag throughout the cycle. The amplitude of lift and drag increased as the morphing frequency and/or trailing edge deflection increased. It was found that the wake characteristics varied as a function of trailing edge deflection and morphing frequency. For small trailing edge deflections below 0.4% and frequencies below a 2.2 Strouhal number, Kelvin Helmholtz shedding was observed, and above this the wake became chaotic. Large trailing edge deflections showed Von-Karman shedding, where the interaction between the lower counter-clockwise vortex and the ground plane resulted in a jet-like flow that caused forward thrust. For the maximum deflection and morphing frequency tested in this study, reversed Von-Karman shedding was observed, which caused forward thrust from the interaction of the two-shedding counter-rotating vortices. Von-Karman or reversed Von-Karman shedding shows positive thrust generation, however, chaotic shedding should be avoided due to large drag gains. Varying the Reynolds number caused the Strouhal number to change as they depend on the same variables. It was found that the Strouhal number variation had a large effect on the wake, however, the Reynolds number had a minimal effect.

Under the leadership of its founding editor, Dante Cicchetti, Development and Psychopathology has been recognized for decades as the foremost journal integrating developmental theory and clinical research programs. Contributors have often highlighted the implications of attachment theory and research for understanding developmental processes and pathways, and as a testing ground for intervention strategies. In this paper we reflect on the strengths and limitations of the traditional developmental perspective. We suggest that behavioral, cognitive, and emotional development are better understood as a process of bricolage (construction within constraints). This perspective is illustrated in an analysis of change mechanisms, and behavioral and representational changes, in attachment development from pre-locomotor infancy to later adulthood. Special emphasis is placed on ordinary learning and cognitive processes, rather than those specific to attachment, and on the roles that socialization pressures and changing circumstances play in shaping the course of attachment development.
