The number of regenerated arms was counted on specimens of two distinct phenotypes of the stalked crinoidEndoxocrinus parrae(Gervais) from a wide bathymetric range in the Caribbean (178-723 m). In one phenotype, the sample was divided into two groups, one from shallower (< 500 m) depths, the other from deeper (≥ 500 m); in the other phenotype the group divided at 550 m. In both phenotypes, the frequency of regenerated arms is significantly higher in specimens from shallower water than in those from deeper water. If the regenerated arms inEndoxocrinus parraewere the result of sublethal predation, as previously suggested, then predation intensity is higher in shallow water than deep water. These results are consistent with the idea of the late Mesozoic marine revolution—that there has been stronger predation on various invertebrates in shallow-water environments since the late Mesozoic. The stalked crinoids may have been unable to cope with increased predation in shelf environments, and they migrated to offshore environments.

Modern crinoids are dominated by the comatulids (unstalked forms) which range from the intertidal to abyssal depths. Modern stalked crinoids are restricted to depths greater than about 100 m. In the geologic past some stalked crinoids lived at depths of a few tens of meters or less in reef and bank environments. The primary vehicles postulated for the post-Triassic radiation of comatulids are lack of permanent fixation to the substratum and the capacity for mobility. Development of complex muscular articulations has enabled crawling or swimming which serve in habitat selection and avoidance of stress and predators. These and other adaptations may have bestowed on comatulids a higher survival capacity in shallow-water environments compared to stalked crinoids. Modern stalked crinoids lack mobility and complex behavioral adaptations seen in comatulids. Possibly, stalked crinoids in shallow water were unable to cope with the radiation of abundant, predaceous bony fishes in the late Mesozoic and became restricted to greater depths while the more adaptable comatulids gained ascendancy in shallow water.

AbstractIn this contribution we describe and illustrate 14 coral morphospecies collected from the early Miocene Siamaná (Aquitanian–Burdigalian) and Jimol (late Burdigalian) formations of the Cocinetas Basin in La Guajira Peninsula, northern Colombia. Eleven were identified as already established species including seven genera belonging to the families Mussidae, Pocilloporidae, Poritidae, Siderastreidae, and Milleporidae; the other three remain in open nomenclature. Nine of the 11 species identified (81%) are extinct. The remaining two living species,Siderastrea sidereaandMillepora alcicornis, are common on modern Caribbean reefs. Their presence in the Siamaná Formation extends their temporal range in the Caribbean region to the early Miocene. Most of the taxa described here were hermatypic and zooxanthellate corals of the order Scleractinia, with the exception of the fire coralMillepora alcicornis, of the order Anthothecata, family Milleporidae. The coral fauna recorded in the Siamaná and Jimol formations is typical of shallow and calm waters of the Oligocene–Miocene transition.

Through SCUBA and skin diving various shallow water ecosystems (rocky shores, soft bottoms and coral reefs, 0-30 m deep) were surveyed to collect telestaceans and penatulaceans octocorals; the areas considered were Cartagena, the Rosario islands, Tierra Bomba island, Barú island, San Bernardo islands, Bushnell and Salmedina banks, Capurgana and Zapzurro harbours (8°20,-10°45, N; 75°50,-77°251 W), the Santa Marta area (11°14,50" N; 74°15, W) y and the Guajira (11 °56,58" N; 72°16'18" W), Colombian Caribbean. Stylatula diadema Bayer (Virgulariidae: Pennatulacea) is first recorded for the Caribbean sea and has been found inhabiting soft sand bottoms between 25 and 30 m, at the outer end of Cartagena Bay and the Mangles Bank in San Bernardo islands. The geographic distribution of Carijoa riisei (Duchassaing y Michelotti) (Telestidae: Telestacea) was widen from the Caribbean and Colombia, it has been found in a broad bathymetric range (0.5-30 m) in all the habitats surveyed. Few records of telestaceans and pennatulaceans in this region, as in the rest of the Caribbean, suggest that the octocorallian fauna is mostly represented by gorgonians than by other orders, and shows an inverse relationship with the Indopacific fauna, where the alcyonaceans are the dominant order.

The English of the West Indies, like the other languages of the area, shows many resemblances to the language patterns of Negroes in other parts of the New World. There have been many controversies over this matter, with many linguists, especially dialect geographers, inclined to deny West African influence upon anything inside continental North America except for Gullah(Georgia and South Carolina sea islands) and the French Creole of Louisiana. Others, like Lorenzo Turner, who conclusively disproved the widely held belief that Gullah was an amalgam of archaic features from the British Isles,have substantiated the thesis of the anthropologist Melville J. Herskovits that the culture, including the language, of Negroes from Suriname to Michigan retains many traces of African patterns. And, since the recent death of the Haitian philologist Jules Faine, no one has seriously denied resemblances among the Caribbean dialects.

Abstract Stuart Hall in Black Britain claims that “the experience of black settlement has been a long, difficult, sometimes bitterly contested and unfinished story.” Such is the case in Samuel Selvon’s 1956 novel The Lonely Londoners, which depicts the trauma of diaspora for West Indian newcomers. People from the Caribbean who settle in the “mother country” experience total disillusion because they are not welcomed by the white British. The paper focuses on the influence British politics has had upon the Windrush generation of immigrants. It shows how the characters cope with animosity, loneliness and the sense of failed promise that all lead to the traumatic experience of living in total isolation in a foreign city far from their native islands. The immigrants face xenophobia, suffer from being the “other”, invisible and segregated. They try to cope with the trauma of “not belonging anywhere”, i.e. being uprooted from their homes in the West Indies. In the aftermath of the decolonization process they fail to come to terms with their new living conditions, and as there is no return ticket to the Caribbean, they experience the ever-growing trauma of unsuccessful resettlement.

Ahmet Hamdi Tanpinar (1901-1962) is one of the most controversial authors in the 20th century Turkish literature. Literature critics find it difficult to place him in a school of literature and thought. There are many reasons that they have caused Tanpinar to give the impression of ambiguity in his thoughts through his literary works. One of them is that he is always open to (even admires) the "other" thought to a certain age, and he considers synthesis thinking at later ages. Tanpinar states in the letter that he wrote to a young lady from Antalya that he composed the foundations of his first period aesthetics due to the contributions from western (French) writers. The influence of the western writers on him has also inspired his interest in the materialist culture of the West. In 1953 and 1959 he organized two tours to Europe in order to see places where Western thought and culture were produced. He shared his impressions that he gained in European countries in his literary works. In the literary works of Tanpinar, Europe comes out as an aesthetic object. The most dominant facts of this aesthetic are music, painting, etc. In this work, in the writings of Tanpinar about the countries that he travelled in Europe, some factors were detected like European culture, lifestyle, socio-cultural relations, art and architecture, political and social history and so on. And the effects of European countries were compared with Tanpinar’s thought and aesthetics. Keywords: Ahmet Hamdi Tanpinar, Europe, poetry, music, painting, culture, life

The Euro-enslavement enterprise in America expanded the European geography temporarily, and, more lastingly, its culturo-linguistic and philosophical influence. The deportation of millions of Africans within that enterprise similarly extended the African presence in this part of the world, especially in the Caribbean. Africans deported by the French Empire spoke languages of the West Atlantic Mande, Kwa, or Voltaic groups. They arrived in their new and final location with their languages. However, no African language wholly survived the ordeal of enslavement in the Caribbean. This signals language as perhaps the most important political and philosophical instrument of colonization. I am therefore interested in “Pawòl,” that is, the ethical, human, and humanist responses Africans brought to their situation through language per se and African languages principally. I am also interested in the metaphysical value of “Pawòl.”

Transnational films representing intimacy and inequality disrupt and disgust Western spectators. When wounded bodies within poverty entangle with healthy wealthy bodies in sex, romance and care, fear and hatred combine with desire and fetishism. Works from the Philippines, South Korea, and independents from the United States and France may not be made for the West and may not make use of Hollywood traditions. Rather, they demand recognition for the knowledge they produce beyond our existing frames. They challenge us to go beyond passive consumption, or introspection of ourselves as spectators, for they represent new ways of world-making we cannot unsee, unhear, or unfeel. The spectator is redirected to go beyond the rapture of consuming the other to the rupture that arises from witnessing pain and suffering. Self-displacement is what proximity to intimate inequality in cinema ultimately compels and demands so as to establish an ethical way of relating to others. In undoing the spectator, the voice of the transnational filmmaker emerges. Not only do we need to listen to filmmakers from outside Hollywood who unflinchingly engage the inexpressibility of difference, we need to make room for critics and theorists who prioritize the subjectivities of others. When the demographics of filmmakers and film scholars are not as diverse as its spectators, films narrow our worldviews. To recognize our culpability in the denigration of others unleashes the power of cinema. The unbearability of stories we don’t want to watch and don’t want to feel must be borne.

Ideologically motivated attempts to elucidate Shostakovich’s political views and to determine whether and how they may be coded into his compositions have come to characterize the Western reception of the composer’s works since his death in 1975. Fuelled by the political oppositions of the cold war, Shostakovich’s posthumous reputation in the West has been largely shaped by two conflicting perspectives. These have positioned him on the one hand as a secret dissident, bent and broken under the unbearable strain of totalitarianism, made heroic through his veiled musical resistance to Communism; and on the other hand as a composer compromised by his capitulation to the regime – represented in an anachronistic musical style. Both perspectives surrender Shostakovich and his music to a crude oversimplification driven by vested political interests. Western listeners thus conditioned are primed to hear either the coded dissidence of a tragic victim of Communist brutality or the sinister submission of a ‘loyal son of the Communist Party’.1 For those prepared to accept Shostakovich as a ‘tragic victim’, the publication of his purported memoirs in 1979, ‘as related to and edited by’ the author Solomon Volkov, presents a tantalizing conclusion: bitterly yet discreetly scornful of the Stalinist regime, Shostakovich was indeed a secret dissident and this dissidence was made tangible in his music.

The essay shows how Ezenwa–Ohaeto's poetry in pidgin, particularly in his collection (1988), emblematizes a linguistic interface between, on the one hand, the pseudo-pidgin of Onitsha Market pamphleteers of the 1950s and 1960s (including in its gendered guise as in Cyprian Ekwensi) and, on the other, its quasicreolized form in contemporary news and television and radio dramas as well as a potential first language. While locating Nigerian Pidgin or EnPi in the wider context of the emergence of pidgins on the West African Coast, the essay also draws on examples from Joyce Cary, Frank Aig–Imoukhuede, Ogali A. Ogali, Ola Rotimi, Wole Soyinka, and Tunde Fatunde among others. It is not by default but out of choice and with their 'informed consent' that EnPi writers such as Ezenwa–Ohaeto contributed to the unfinished plot of the pidgin–creole continuum.
