During the Late Classic period (a.d. 550–900), ancient Maya settlement spread throughout western Belize, including the Vaca Plateau, a rugged karstic region with high densities of ritually utilized cave systems. Within the past decade, archaeologists have increasingly drawn on LiDAR technology to document the extent of such settlement at local and regional scales. Combined with traditional pedestrian survey, we have begun to amass substantial data on variation within household groups, disparities which may indicate inequality within these communities. Here, we use settlement data generated from the Las Cuevas region to quantify residential variation through Gini coefficients and Lorenz curves. Special attention is given to areal and volumetric deviation of identified households within three samples: (1) the complete 95.25 km2 study area; (2) a 12.25 km2 zone of higher population between the primary centers of Las Cuevas and Monkey Tail; and (3) households situated within 500 m of ritually utilized caves within the study area. Results indicate some degree of variation within household area and volume for all samples, suggestive of unequal access to labor within the region. This research adds to the growing database of Gini-based analyses to improve our understanding of wealth differentials within pre-modern populations throughout the Lowlands.

In Born losers: a history of failure in America (2005), historian Scott A. Sandage traces how, through the course of the nineteenth century, business failures gradually morphed into personal failures. Where losing money initially meant just that by the later nineteenth century, as the narrative of the ‘self-made man’ took hold, it came to be seen by society as a personal shortcoming and framed as a moral judgement. Fast-forward to the big-tech era of the twenty-first century and failure has become a trophy rather than a scar. Silicon Valley's credo of ‘fail fast and fail forward’ entrenches failure not only as a standard element of business practice—start-ups are expected to fail, their founders slated to move forward on their path to success—but also as a commendable addition to a CV or resumé thought to reflect ambition, innovativeness and resilience (see critique in Myers 2019). This admittedly truncated narrative of failure in America, closely intertwined with capitalist profit-seeking, serves to illustrate that failure is not a neutral concept but rather a social phenomenon, the reality and valence of which are context dependent. Moreover, like all social phenomena, failure has a history.

We have all heard horror stories of ChatGPT making information professionals redundant and taking over the world, but just how proficient is it at good old legal research? Greg Bennett, a law librarian at BPP, invested in the premium version of the package to put it to the test.

The inherent stochastic and nonlinear nature of the solar dynamo makes the strength of the solar cycles vary in a wide range, making it difficult to predict the strength of an upcoming solar cycle. Recently, our work has shown that by using the observed correlation of the polar field rise rate with the peak of polar field at cycle minimum and amplitude of following cycle, an early prediction can be made. In a follow-up study, we perform SFT simulations to explore the robustness of this correlation against variation of meridional flow speed, and against stochastic fluctuations of BMR tilt properties that give rise to anti-Joy and anti-Hale type anomalous BMRs. The results suggest that the observed correlation is a robust feature of the solar cycle and can be utilized for a reliable prediction of peak strength of a cycle at least 2 to 3 years earlier than the minimum.

Rapid technological change is resulting in the development of ever increasingly capable autonomous weapon systems. As they become more sophisticated, the calls for developing restrictions on their use, up to and including their complete prohibition, are growing. Not unlike the call for restrictions on the sale and use of drones, most proposed restrictions are well-intentioned but are often ill-informed, with a high likelihood of degrading national security and putting additional lives at risk. Employed by experienced operators well-versed in the laws of armed conflict, autonomous weapons can advance the objectives of those who would prohibit their use. This essay takes an operational perspective to examine the role that autonomous weapon systems can play while complying with the laws of armed conflict. With responsible design and incorporation of applicable control measures, autonomous weapons will be able not just to comply but also to enhance the ethical use of force. This essay contends that efforts by the international community to use international legal means and/or institutions to over-regulate or even ban lethal autonomous weapons are counterproductive. It considers and describes the end-game results of the use of autonomous weapons in enhancing the application of both international law and human ethical values.

Fluvial and colluvial deposits of Late Holocene age in South-Central Ontario catchments have provided few 14C dates, most by conventional methods registering century-old ages. Other young deposits, dated by conventional and accelerator mass spectrometry radiocarbon (AMS 14C), have yielded bomb-affected post-1950 ages over variable time limits. Attempts to date the base of Ah and lower-in-section soil horizons, in Early to Late Holocene stream terrace deposits, have yielded atomic bomb effects. Comparing bomb contamination in Late Holocene fluvial deposits, using both conventional and AMS methods, identifies a mix of bomb-affected beds juxtaposed with dated beds, the latter yielding ages with narrow standard deviations. Colluvial deposits overlying key glacial sections in the Rouge Catchment, while rare, yield bracketed AMS ages for an Ahbk horizon that refines weathering times relative to previously obtained conventional 14C dates. Bomb-affected sediment appears variably distributed within floodplain soils and in the ground soil of a colluvial section. Mass wasted deposits, with AMS 14C ages spread over the last few centuries, appear related to Little Ice Age (LIA) changes in climate, corroborated by pollen records. Further, these AMS-14C dated beds calibrate weathering of secondary Fe-Al oxihydroxides over the first half a millennium of weathering time.

A lack of transparency and concerns over patients costs at the pharmacy counter have increased Congressional focus on pharmacy benefits management practices. However, applying regulations without transparency into pharmacy benefits managers practices could do more harm than good.

Vitruvius’ famous description of the homo bene figuratus possesses a slightly paradoxical nature. The description is meant to illuminate a fundamental but very abstract principle underlying the building of temples: symmetry or proportion. For the purpose of illumination, an analogy is drawn between temples and the human body. But even though the description serves an illustrative purpose, it does not at first sight appear to have a specifically illustrative nature since it largely consists of numerical fractions and proportional relations. Additionally, it seems quite difficult to tell what the homo bene figuratus actually looks like because the figure hardly possesses any individual features. And yet, the description inspired a rich reception of drawings during the Renaissance and later (of which Leonardo's version is certainly the most famous). The passage even seems to have taken on a life of its own since in those drawings the homo bene figuratus is usually treated independently of its original purpose and remains unconnected with temples or other buildings. Apparently, the passage—somehow—has an easily comprehensible or even perhaps vivid quality, despite the fact that it mainly lists abstract numerical details.

Conjectures are made on the text of three passages in Tibullus, Books 1–2: 1.4.26 hastam … suam for crines … suos, 2.1.56 membra for bache, 2.4.60 aliis rebus for alias herbas.

This article considers how the archive, particularly material produced by children, destabilizes the boundaries between the domestic and the foreign, citizenship and empire. Through its analysis of a wave of educational reform in the United States during the 1930s, which encouraged global citizenship among the young, it demonstrates how children not typically associated with global citizenship – those from both rural and working-class backgrounds – engaged with the imperial messages embedded in global education of the period.

This article examines the process of nation-building in post-colonial Qatar. By using a postcolonial lens, the study discusses the historical context of Qatar’s state formation, tracing the impact of colonialism and the role of external powers in shaping political structures and narratives. Through an analysis of key historical figures and events, such as Shaykh Jassim and the Qatari constitution, this article explores the use of tradition and indigenous modernity in the construction of Qatar’s national identity. By drawing on theoretical frameworks such as “invented traditions,” “imagined communities,” and the politics of tradition and modernity, the article provides a roadmap to understanding the main tenets of the national identity politics of Qatar today and key factors of its national identity narratives, including ethno-political migrations, citizenship dynamics, and institutional frameworks established by the state constitution. It argues that while nation-building processes may share commonalities across different geographies, the specific historical, cultural, and political dynamics of Qatar shaped its unique trajectory. Ultimately, the article contributes to a deeper understanding of the complexities of nation-building in post-colonial contexts and the construction of national identity in the Gulf region
