Marine autonomous systems, be they underwater or surface vehicles are growing in numbers, maturing as technologies used by civil, science and military operators, and are gaining new capabilities. It is possible to insure autonomous systems at a reasonable rate. The regulatory frameworks pertaining to their use vary from country to country, but the international law for armed marine autonomous systems is out of date and would benefit from revision and update. This paper is a light-touch review of typical uses and capabilities of systems, does not contain classified or commercial in confidence material, based on the author's 25+ years of familiarity with marine autonomous systems as they have evolved from laboratory prototypes into routinely used platforms for science, survey and surveillance.

An obituary discussing the life of Raphael Samuel, a founder of the New Left Review, who died of cancer in 1996.

Caribbean political leaders & writers' struggles to determine Caribbean cultural identities are examined. It is contended that the struggle to define Caribbean cultural identities has been one of the most significant problems tackled by 20th century Caribbean political activists & writers. Several circumstances that have problematized efforts to circumscribe Caribbean cultural identities are highlighted including the difficulties of determining Caribbean people's cultural & historical origins. Three processes presently affecting Caribbean cultural identities are subsequently identified: the retention of both colonialist & African cultural traditions; the pervasive efforts to assimilate local Caribbean cultures into the cultures of their colonial European descendants; & the influence of various black movements (eg, negritude, the Harlem Renaissance, & Rastafarianism) upon Caribbean culture. It is concluded that Caribbean political leaders & writers should embrace, not overlook, the multiple cultural heritages present within contemporary Caribbean society & utilize them to construct Caribbean cultural identities.

Suggests that the repertoires of black popular culture, which, since black people were excluded from the cultural mainstream, were often the only performative spaces left, were overdetermined from 2 directions: from their inheritances; and by diasporic conditions in which the connections were forged.

THIS ARTICLE EXAMINES THE STRUCTURE AND COMPOSITION OF THESE "NEW TIMES." KNOWN BY SEVERAL TERMS INCLUDING "POSTINDUSTRIAL," "POST-FORDIST," "REVOLUTION OF THE SUBJECT," AND POSTMODERN," THIS TRANSFORMED SOCIETY HAS MANY IMPLICATIONS FOR POLITICS ON THE LEFT. THE "PROMISE" OF MODERNITY HAS BECOME, AT THE END OF THE 20TH CENTURY, CONSIDERABLY MORE AMBIGUOUS, ITS LINKS WITH SOCIALISM AND THE LEFT MUCH MORE TENUOUS. THE SWEEPING CHANGES HAS ALSO MADE IT DIFFICULT TO CONCEIVE OF "THE INDIVIDUAL" IN TERMS OF A WHOLE AND COMPLETED EGO OR AUTONOMOUS "SELF." THE "SELF" IS EXPERIENCED AS MORE FRAGMENTED AND INCOMPLETE, COMPOSED OF MULTIPLE "SELVES" OR IDENTITIES IN RELATION TO THE DIFFERENT SOCIAL WORLDS INHABITED.

IS THERE A POLITICAL FORCE CAPABLE OF SETTING ASIDE THE SLOGAN OF THE "BROAD DEMOCRATIC ALLIANCE" AND "POPULAR DEMOCRATIC STRUGGLE," AND ENTERING--DIRECTLY IN THE TEETH OF THE CRISIS--INTO THE POLITICS AND THE PRACTICE OF THIS WAR OF POSITIONS AGAINST THE RADICAL RIGHT? THIS ARTICLE ATTEMPTS TO ANSWER THIS QUESTION.

An analysis of faecal samples and stomach contents of Antechinus stuartii and A. swainsonii inhabiting forest in southern Victoria revealed a large overlap in the type and size of prey items taken by these dasyurids. The frequencies of 23 prey types and 15 prey sizes in the diets of these predators were both positively correlated. Weevils (Coleoptera, Curculionidae) represented the only difference in prey types not attributed to individual variations. A. stuartii took more, and a wider size range of, weevils than did A. swainsonii; the trophic diversity index of prey types was greater for A. stuartii. The larger A. swainsonii took more prey greater than 20 mm; it took prey on the average 23% longer and 75% heavier than did A. stuartii; the trophic diversity index of prey size was greater for A. swainsonii. It is concluded that these morphologically distinct predators are exploiting the same large population of prey. They are both generalists and appear to be opportunistic feeders.
