Plane Hijackings between Cuba and the United States and the Opportunity for Diplomacy (1958–1973)
Authors: Porat Dan 
Published: February 2024

AbstractBetween 1958 and 1973, hijackings between Cuba and the US surged, prompting Cuban officials in the early 1960s to propose an extradition agreement for hijackers. However, the US, leveraging its superpower status, dismissed these initiatives, viewing hijackers as political asylum seekers rather than criminals. By the late 1960s, as hijackings escalated from the US to Cuba, the American approach shifted, seeking a bilateral agreement to address air piracy, only to be rebuffed by Cuba, which refused to accept the US’s categorization of specific hijackers as political asylum seekers while classifying others as criminals. Meanwhile, the US pressed its extradition stance through international bodies like the International Civil Aviation Organization. These diplomatic efforts underscored broader challenges in US–Cuban relations, with negotiations repeatedly missing opportunities for enhanced co-operation. A pivotal shift occurred after a significant incident threatened both nations, leading to a more balanced perspective between the US and Cuba. This change culminated in the 1973 signing of a ‘Memorandum of understanding’, marking a turning point that significantly curbed hijacking incidents and hinted at potential future improvements in bilateral relations.
From Natives to Foreigners: Bolivian Migration, Discrimination, and Ethnic-Labor Subsidiarity in Chuquicamata During the Guggenheim Ownership (Chile, 1912–1925)

AbstractThe War of the Pacific (1879–1883) between Chile, Peru, and Bolivia marked a turning point in the political and socio-economic development of the Atacama Desert. Formerly part of Bolivia, this area came under the control and jurisdiction of Chile in 1884. This shift in sovereignty substantially altered the tri-national geopolitics, forcing the local Bolivian population to flee. The newly annexed region's rich mineral resources became subject to a mining colonization process. In 1912, the Guggenheim family founded The Chile Exploration Company and began the industrialization of the Chuquicamata copper mine. Located in the heart of the Atacama Desert, this was the world's largest copper mine during the twentieth century. Although the local Bolivian population had fled the Atacama Desert following the war, many returned to work in the Guggenheim mine almost thirty years later. Between 1912 and 1925, 239 Bolivians labeled as foreigners and “Indians” were employed in diverse production stages or subsidiary services. Bureaucratic migratory documents and newspaper archives allow us to quantify and characterize Bolivian migration to Chuquicamata. We argue that an ethnic-labor subsidiarity emerged, a historical process resulting from ethnic discrimination, expressed in the disposition and physical costs of mining work and low wages. While the war altered the mining territory of Atacama, ethnic-labor subsidiarity of the Bolivian workforce sustained the expansion of U.S. capitalism in the Chuquicamata copper mine.
Renegotiating Skills, Wages, and the Right to Work: On the Gender of Labor Activism around Rationalization in the Bulgarian Tobacco Industry in the Early 1930s
Authors: Masheva Ivelina Lyubenova 
Published: February 2024

AbstractStarting from the early 1930s, structural changes in the Bulgarian tobacco industry, prompted by the advent of the world economic crisis and German economic expansionism into Southeastern Europe, led to a deep restructuring of the labor processes, known in the terminology of the time as rationalization, in the Bulgarian tobacco industry. The introduction of the tonga rationalization technology had a deskilling and deeply gendered effect on the industry, making a significant number of skilled male workers redundant, disproportionately decreasing average male wages and leading, in turn, to a further feminization of an already majority-female workforce.The introduction of the new system provoked a strong response from the organized labor movement, which used a variety of tactics to fight against the new technology: from strikes to petitions to tripartite negotiations. Organized labor's reaction was deeply gendered, an aspect that only becomes truly visible if, in addition to gender and skill, we employ the analytical lens of scale. By following trade union policies on the local, national, and international levels, the article goes beyond the carefully crafted gender-neutral language in official documents to reveal tensions between the conservative attitudes of rank-and-file activists and the official trade union agenda. This is especially evident in communist labor politics, where Bulgarian trade union policies on the local and national levels provoked an intervention on the part of the Profintern between 1930 and 1931. The movement's internal contradictions resulted in a polyvalent, ambiguous, and non-linear trade union policy formed through the clash of and negotiations between local activists’ conservative notions of gendered work and family roles and the radical gender program of international communism.
Measuring children's metalinguistic awareness
Authors: Roehr-Brackin Karen 
Published: February 2024

Abstract
Research into young learners' metalinguistic awareness has led to both definitions of the construct and key findings about its role in children's cognitive and linguistic development. I briefly summarise this research before introducing two established theoretical models that can help us understand the concept of metalinguistic awareness more broadly: Ellen Bialystok's classic dichotomy of analysis of knowledge and control of processing, and Rod Ellis's notion of explicit (second language) knowledge. This is followed by an overview of measures of metalinguistic awareness that have been used in empirical studies to date as well as an illustration and critique of selected measures. As a result, I propose a model that combines features of the two previous frameworks by conceptualising knowledge representations and processes in terms of (1) how implicit/explicit and (2) how specific/schematic they are. I explain this model to illustrate how it can serve as a useful thinking tool. In particular, I argue that the model not only allows us to theorise measures of metalinguistic awareness more clearly and easily, but that it can also capture tasks aimed at assessing other linguistic and cognitive abilities. The article concludes with a brief outlook on future research into metalinguistic awareness.
The impact of the British Civil Wars on the meanings and uses of the urban topography of Colchester in the long nineteenth century
Authors: Sewell Michael 
Published: February 2024

AbstractAlthough many towns repaired, restored or destroyed the ruins of Civil War sieges, there are a number of towns, villages and hamlets which still clearly bear marks of the conflict. By focusing on Colchester, this article will highlight how sites affected by the wars remained and survived in the local consciousness throughout the following centuries. This article traces the uses of such sites in the urban landscape in the eighteenth and nineteenth centuries to assess the long-term impact of the war on towns in the British Isles. By examining Colchester in 1648, the article will show how political parties, parishes, tourists and businesses all derived value from the sites of the siege centuries after it had ended.
Smugglers and innkeepers: physical and social mobility in early modern Gemona (fifteenth to seventeenth centuries)
Authors: Di Bari Alessandro 
Published: February 2024

Abstract
This article examines the mechanics of Niederlech (a law that obliged merchants travelling between Germany and Italy to spend the night in the city, change wagons and pay a small sum of money) and German–Italian mobility in early modern Gemona. It argues that the fragility of Venetian institutions and a lack of German–Italian border controls set the scene for criminal activities, especially contraband, in which Gemona innkeepers appear to have played a significant part. It will also show that this illegal trafficking led to a new ruling class forming, a key factor in the city’s reorganization of social hierarchies.
Investigating the Linkage Between Spiral Trough Morphology and Cloud Coverage on the Martian North Polar Layered Deposits

Published: February 2024

AbstractThe martian North Polar layered deposits (NPLD) are composed of alternating water‐ice and dust‐rich layers resulting from atmospheric deposition and are key to understanding Mars climate cycles. Within these deposits are spiral troughs whose migration affects deposition signals. To understand the relationship between NPLD stratigraphy and Martian climate, we must identify modern‐day drivers of NPLD ice migration. Prevailing theory posits migration driven by upstream‐migrating bed undulations bounded by hydraulic jumps, caused by katabatic winds flowing over trough walls with asymmetric cross‐sectional relief. This is supported by trough‐parallel clouds, whose formation has been attributed to hydraulic jumps. We present a cloud atlas across the Martian north pole using ∼13,800 THEMIS images spanning ∼18 Earth years. We find trough‐parallel clouds in ∼400 images, with regions nearer to the pole having higher cloud frequency. We compare spiral trough geometry to our cloud atlas and find regions with trough‐parallel clouds often correlate with metrics associated with modern‐day sublimation‐deposition cycles (i.e., relief and asymmetry), but not always. In some regions, troughs with morphologies conducive to cloud formation have no clouds. Overall, trough geometry varies greatly across the deposits, both within and between troughs, suggesting localized differences in deposition relative to migration, varying katabatic wind intensities, differing past climatic states influencing the troughs, varying trough initiation properties, or the possibility of additional mechanisms for trough initiation and migration (e.g., in situ trough erosion). Understanding what controls trough shape variability across the NPLD and how these controls change through time and space is key when interpreting Martian paleoclimate.

AbstractCoral reef islands are biodiversity hotspots with high conservation value, but we have a poor understanding of how island vegetation, through transpiration, influences groundwater nutrient supply to adjacent reef systems. Here we combine stable isotope tracing, geophysical surveys, and satellite analysis to unravel the links between transpiration and the discharge of groundwater nitrate to the waters surrounding a coral reef island (Lady Elliot Island in the Great Barrier Reef). Over a 2‐year study period (2020–2021) there was a net loss of freshwater from the island, that is, evapotranspiration (ET) exceeded rainfall, largely caused by high rates of transpiration (73% of ET). Transpiration was higher in forested areas, and groundwater salinity appeared to be higher there. By tracing the nitrogen stable isotope signature of groundwater nitrate into reef organism tissue we were able to map groundwater nitrogen discharge spatially and temporally. Groundwater nitrogen discharge was focussed on one side of the island and did not vary seasonally as expected, despite reduced rainfall and seabird guano inputs over the austral winter/spring. Based on our results, we propose that transpiration by island vegetation slows groundwater flow and concentrates nitrate in the groundwater being released to the surrounding reef system. High concentrations of nitrate in groundwater (up to 27 mmol L−) were observed on Lady Elliot Island and these seem to have increased since 2014, but further work is required to understand if this is a normal scenario for tropical coral islands or the result of the islands' revegetation program.

AbstractThe use of post-transplantation cyclophosphamide (PTCy) for graft-versus-host disease (GVHD) prophylaxis is not established after reduced intensity conditioning (RIC) hematopoietic stem cell transplantation (HSCT) from fully matched donors. This was a randomized, open-label, multicenter, phase 2 trial. All patients received a RIC regimen with fludarabine, intravenous busulfan for 2 days (Flu-Bu2), and a peripheral blood stem cell (PBSC) graft from a matched related or 10/10 HLA-matched unrelated donor. Patients were randomly assigned to receive anti-thymocyte globulin (ATG) 5 mg/kg plus standard GVHD prophylaxis or PTCy 50 mg/kg/d at days +3 and +4 plus standard GVHD prophylaxis. The primary endpoint was the composite endpoint of GVHD- and relapse-free survival (GRFS) at 12 months after HSCT. Eighty-nine patients were randomly assigned to receive either PTCy or control prophylaxis with ATG. At 12 months, disease-free survival was 65.9% in the PTCy group and 67.6% in the ATG group (P = 0.99). Cumulative incidence of relapse, non-relapse mortality, and overall survival were also comparable in the two groups. GRFS at 12 months was 54.5% in the PTCy group versus 43.2% in the ATG group (P = 0.27). The median time to neutrophil and platelet count recovery was significantly longer in the PTCy group compared to the ATG group. Except for day +30, where EORTC QLQ-C30 scores were significantly lower in the PTCy compared to the ATG group, the evolution with time was not different between the two groups. Although the primary objective was not met, PTCy is effective for GVHD prophylaxis in patients receiving Flu-Bu2 conditioning with a PBSC graft from a fully matched donor and was well tolerated in term of adverse events and quality of life. This trial was registered at clinicaltrials.gov: NCT02876679.

AbstractSickle cell disease (SCD) is a single gene blood disorder characterised by frequent episodes of pain, chronic anaemic, acute chest syndrome, severe disease complications and lifelong debilitating multi-system organ damage. Genetic testing and screening programs for SCD and the sickle cell trait (SCT) are valuable for early diagnosis and management of children living with SCD, and in the identification of carriers of SCT. People with SCT are for the most part asymptomatic and mainly identified as through genetic testing or when they have a child with SCD. This qualitative study explored perceptions towards genetic testing for SCD and SCT in Cameroon, Ghana, and Tanzania. The results show a general preference for newborn screening for SCD over prenatal and premarital/preconception testing, primarily due to its simpler decision-making process and lower risk for stigmatization. Premarital testing for SCT was perceived to be of low public health value, as couples are unlikely to alter their marriage plans despite being aware of their risk of having a child with SCD. Adolescents were identified as a more suitable population for SCT testing. In the case of prenatal testing, major concerns were centred on cultural, religious, and personal values on pregnancy termination. The study revealed a gender dimension to SCD/SCT testing. Participants mentionned that women bear a heightened burden of decision making in SCD/SCT testing, face a higher risk of rejection by potential in-laws/partners if the carriers of SCT, as well as the possibility of divorce if they have a child with SCD. The study highlights the complex cultural, ethical, religious and social dynamics surrounding genetic testing for SCD and emphasises the need for public education on SCD and the necessity of incorporating genetic and psychosocial counselling into SCD/SCT testing programs.

AbstractBiallelic loss-of-function variants in TBC1D2B have been reported in five subjects with cognitive impairment and seizures with or without gingival overgrowth. TBC1D2B belongs to the family of Tre2-Bub2-Cdc16 (TBC)-domain containing RAB-specific GTPase activating proteins (TBC/RABGAPs). Here, we report five new subjects with biallelic TBC1D2B variants, including two siblings, and delineate the molecular and clinical features in the ten subjects known to date. One of the newly reported subjects was compound heterozygous for the TBC1D2B variants c.2584C>T; p.(Arg862Cys) and c.2758C>T; p.(Arg920*). In subject-derived fibroblasts, TBC1D2B mRNA level was similar to control cells, while the TBC1D2B protein amount was reduced by about half. In one of two siblings with a novel c.360+1G>T splice site variant, TBC1D2B transcript analysis revealed aberrantly spliced mRNAs and a drastically reduced TBC1D2B mRNA level in leukocytes. The molecular spectrum included 12 different TBC1D2B variants: seven nonsense, three frameshifts, one splice site, and one missense variant. Out of ten subjects, three had fibrous dysplasia of the mandible, two of which were diagnosed as cherubism. Most subjects developed gingival overgrowth. Half of the subjects had developmental delay. Seizures occurred in 80% of the subjects. Six subjects showed a progressive disease with mental deterioration. Brain imaging revealed cerebral and/or cerebellar atrophy with or without lateral ventricle dilatation. The TBC1D2B disorder is a progressive neurological disease with gingival overgrowth and abnormal mandible morphology. As TBC1D2B has been shown to positively regulate autophagy, defects in autophagy and the endolysosomal system could be associated with neuronal dysfunction and the neurodegenerative disease in the affected individuals.

Abstract
Background/Objectives
To assess the prevalence and correlates of impaired activities of daily living (ADLs) in patients with neovascular age-related macular degeneration (nAMD) who present for anti-vascular endothelial growth factor (VEGF) therapy.

Methods
In a clinic-based cohort of 437 patients with nAMD who presented for anti-VEGF therapy, the Older American Resources and Services Scale (OARS) was administered to assess for impairments in basic, instrumental and total ADL. Logistic regression analyses were conducted to determine odds ratios (OR) and 95% confidence intervals (CI) for factors associated with ADL impairment.

Results
The prevalence of impaired basic, instrumental and total ADL was 37.76%, 67.82% and 39.59%, respectively. In multivariate-adjusted models, moderate visual impairment [OR 5.65, 95% CI (2.31–13.83) and blindness [OR 5.43, 95% CI (2.09–14.12)] were associated with greater odds of impaired total ADL. Depressive symptoms [OR 2.08, 95% CI (1.08–4.00)], the presence of any disability [OR 3.16, 95% CI (1.64–0.07)] and never driving [OR 4.00, 95% CI (1.60–10.00)] were also positively associated with total ADL impairment. Better vision-related quality of life (QoL) was inversely associated with impaired instrumental ADL whilst higher health-related QoL scores were associated with decreased odds of total ADL impairment.

Conclusions
There is a high prevalence rate of ADL impairment among nAMD patients presenting for therapy. Visual impairment, never driving, poor physical and mental health increased the odds of experiencing ADL impairment whilst better VRQoL and HRQoL reduced the odds of impairment.

AbstractFlatbands play an important role in correlated quantum matter and have promising applications in photonic lattices. Synthetic magnetic fields and destructive interference in lattices are traditionally used to obtain flatbands. However, such methods can only obtain a few flatbands with most bands remaining dispersive. Here we realize all-band-flat photonic lattices of an arbitrary size by precisely controlling the coupling strengths between lattice sites to mimic those in Fock-state lattices. This allows us to go beyond the perturbative regime of strain engineering and group all eigenmodes in flatbands, which simultaneously achieves high band flatness and large usable bandwidth. We map out the distribution of each flatband in the lattices and selectively excite the eigenmodes with different chiralities. Our method paves a way in controlling band structure and topology of photonic lattices.

AbstractRecent discovery of emergent magnetism in van der Waals magnetic materials (vdWMM) has broadened the material space for developing spintronic devices for energy-efficient computation. While there has been appreciable progress in vdWMM discovery, a solution for non-volatile, deterministic switching of vdWMMs at room temperature has been missing, limiting the prospects of their adoption into commercial spintronic devices. Here, we report the first demonstration of current-controlled non-volatile, deterministic magnetization switching in a vdW magnetic material at room temperature. We have achieved spin-orbit torque (SOT) switching of the PMA vdW ferromagnet Fe3GaTe2 using a Pt spin-Hall layer up to 320 K, with a threshold switching current density as low as $${J}_{{{{{{\rm{sw}}}}}}}=$$
