Abstract
Foreign actors, particularly Russia and China, are using disinformation as a tool to sow doubts and counterfactuals within the U.S. population. This tactic is not new. From Nazi influence campaigns in the United States to the Soviets spreading lies about the origins of HIV, disinformation has been a powerful tool throughout history. The modern "information age" and the reach of the internet has only exacerbated the impact of these sophisticated campaigns. What then can be done to limit the future effectiveness of the dissemination of foreign states' disinformation? Who has the responsibility and where does the First Amendment draw the boundaries of jurisdiction?

The complexities of climate science, of estimates of global greenhouse gas emissions and of their implications for climate change have not prevented widespread acceptance that global warming is a reality and its consequences potentially catastrophic for our planet and its peoples. But the convoluted processes of international negotiations and the political and economic context of their implementation mean that few have any confidence that national undertakings and international targets will be met. COP26 was a watershed, revealing the lack of progress on the most critical challenge of our time, the hypocrisy and double-speak of capitalist states and corporations, and the co-option of some conservation organisations through a deceptively 'green' narrative. A critical, materialist, Marxist approach can break through the greenwash of official discourse, reveal the need for systemic change, and potentially serve as a focus for growing public awareness and environmental activism.

Food is the basis of life but rarely features as a topic in Marxist analysis. The Marx Memorial Library's series of panel discussions in the autumn of 2021 brought together prominent academics and activists to present a Marxist perspective on the politics of food and agriculture, to examine the changes necessary and how to achieve them.

This paper summarises the history and capabilities of monoplace chambers in treatment of decompression illness (DCI); both in support of diving operations and in the hospital setting. In the field, monoplace hyperbaric chambers provide victims of DCI immediate access to recompression in settings where traditional multiplace chambers are not available. Alternatively, they may facilitate pressurised transport to a multiplace chamber for continued management. Recently, collapsible lightweight versions have improved suitability for field deployment aboard small vessels in remote settings, and for use by less technically capable military, occupational and civilian operators. The resulting elimination of treatment delays may prove lifesaving and central nervous system sparing, and avoid subsequent diving fitness disqualification. Monoplace chambers thus facilitate diving operations that would otherwise be difficult to condone on health and safety grounds. The 1960s saw the introduction of multiplace hyperbaric chambers into the hospital setting, as a number of non-diving conditions appeared to benefit from hyperbaric oxygen. This coincided with interest in hyperbaric oxygen as a solid tumour radiation sensitiser. Development of a novel acrylic-hulled single occupancy chamber enabled patients to undergo radiotherapy while pressurised within its oxygen atmosphere. Increasing numbers of health care facilities adopted this chamber type as a more economical, less complex alternative to the multiplace chamber. Incorporation of relevant biomedical technologies have allowed monoplace chambers to support increasingly complex patients in a safe, effective manner. Despite these advances, criticism of medical centre-based monoplace chamber treatment of DCI exists. This paper evaluates this controversy and presents relevant counter-arguments.

As a doctrinal matter, the Pentagon has formally recognized cyberspace as a new domain of warfare. It has become just as critical to military operations as land, sea, air, and space.â€ These words, written by Deputy Secretary of Defense William Lynn last fall in Foreign Affairs, cemented the status of cyberspace as a domain of warfare like all others, and coincided nicely with US Cyber Command reaching its full operational capacity.
