Gerrymandering has affected U. S. politics since at least 1812. A political cartoon that year decried this tactic by then Massachusetts Governor Elbridge Gerry. (Gerrymandering is manipulating the boundaries of districts to benefit a group unfairly.)

This article examines the legal principles governing the sharing of benefits deriving from the exploration and use of outer space. It shows that, over time, three strands of State practice have developed different understandings of the content of the obligation contained in Article I, paragraph 1 of the Outer Space Treaty. While drawing parallels with other areas of international law, the article examines the role of equity in the structure of the obligation and evaluates the possibility of replacing considerations of equivalence with a proportionality test to facilitate the fulfilment of the benefit sharing obligation under the Outer Space Treaty.

I was seven years old when I read my first comic book. Asterix and Caesar's gift has never really ranked amongst my favourites in the long-running French children's comic book series but the impact it had on me at the time was nothing less than life-changing.

Countries adopted a variety of social policy responses to reduce the social risks exacerbated by the COVID-19 pandemic, which in some cases took the form of institutional reforms. The study of the institutionalisation of emergency responses is relevant to understanding if and how a critical juncture, like the one opened by the pandemic, can generate path dependencies or changes that expand or retrench social protection. This state-of-the-art article offers an overview of how social policy responses to the pandemic have translated to institutional reform across the globe under various types of welfare systems. By conducting a systematic literature review of thirty-nine peer-reviewed journal articles in two leading bibliographic databases (Scopus and Web of Science), this article reviews the available evidence on the responses to the pandemic and their institutional consequences. We find four underlying research clusters regarding the degree of institutionalisation of the social policy responses implemented during the pandemic.

Navigation safety at sea is vital for each autonomous surface vehicle (ASV), which involves the problem of motion planning in dynamic environments and their robust tracking through feedback control. We present a practical path-planning method that generates smooth trajectories for a marine vehicle traveling in an unknown environment, where obstacles are detected in real time by millimetre wave (mmWave) radar. Our approach introduces a polynomial curve to describe the lateral and longitudinal trajectories in the Frenet frame, known as the ‘motion primitives’, whose combination ensures that the planning area is properly covered. In addition, we can select a feasible, optimal and collision-free trajectory from such a set of motion primitives that is generated by considering the vehicle dynamics and comfort. The capabilities of proposed algorithm are demonstrated in the experiment with static and dynamic obstacles.

The Late Holocene Dry Period (LHDP) was a one-plus millennial megadrought (3100–1800 cal BP) that delivered challenges and windfalls to Indigenous communities of the central Great Basin (United States). New pollen and sedimentation rate studies, combined with existing tree-ring data, submerged stump ages, and lake-level evidence, demonstrate that the LHDP was the driest Great Basin climate within the last 6,000 years—more extreme than the well-known Medieval Climatic Anomaly. New evidence reported here documents that most Great Basin archaeological sites south of 40° N latitude were abandoned during the long dry phase of the LHDP (3100–2200 cal BP), sometimes reoccupied during a wet interval (2200–2000 cal BP), and abandoned again during the most extreme drought (2000–1800 cal BP). Even in the face of epic drought, this is a story of remarkable survivance by some people who adjusted to their drought-stricken landscape where they had lived for millennia. Some moved on, but other resilient foragers refused to abandon their homeland, taking advantage of glacier-fed mountain springs with cooler alpine temperatures and greater moisture retention at high altitude, a result of early Neoglaciation conditions across many Great Basin ranges, despite epic drought conditions in the lowlands.
