Abstract:
This study analyses three essential motifs which are perception, visibility and invisibility and how their relationships determine and legislate the interracial relationships between whites and blacks in Ralph Ellison’s novel, INVISIBLE MAN. Through insightful analysis, this paper aims to show how from a visible status in existence, the perception that white people have about black people transforms this visibility into an invisible status both in human existence and society and namely in the white American society. And also it aims to clear out how this metamorphosis of black people from visibility to invisibility at first based on white people's perception, is principally based and due to their color of skin, and to another “Blackness” of Black people or African-Americans color of skin. Creating a real problem of existence and identity for black people through the question: “do I exist?”, the refusal of such perception and invisibility constructed by racism, stereotypes, prejudices and the concept of white people superiority will oblige black people to struggle for their visibility, their true existence, their identity and recognition by white people as an equal human being.

Full text
Abstract:
Lernaeenicus radiatus is a pennellid copepod with a 2-host life cycle that exhibits high host-specificity to their first host, black sea bass Centropristis striata. This parasite was prevalent in the gills of black sea bass juveniles and adults along the coast of New Jersey, USA, April to December 2019. Parasite incidence was high in the summer and fall in near-shore areas and dropped significantly in fish from deep waters further off-shore in December. Heavy infections of L. radiatus occurred in gills of adult black sea bass inhabiting reef-associated structures, in which parasite incidence rate was 2-3.7 times higher than in non-structure habitat. Less host-specificity occurred in second hosts which support female metamorphosis. In total, 7 fish species were confirmed as second hosts, with the most common being Atlantic menhaden Brevoortia tyrannus and bay anchovy Anchoa mitchilli. Incidence of L. radiatus depends on host abundance and habitats that support interactions of the preferred fish hosts, which may explain the heavy infections in reef habitats. The L. radiatus anchor process in metamorphosed females was highly polymorphic, depending on tissue tropism. Parasite length varied considerably, with neck and trunk measurements of L. radiatus from adult menhaden being 2-4 times larger than those from smaller host species. Mitochondrial cytochrome oxidase c subunit I (COI) sequences demonstrated all parasites to be L. radiatus, with sequence divergence limited to 0.3%. These findings show that morphology of the metamorphosed females has poor taxonomic value, and polymorphisms instead are related to attachment site and host characteristics.

Abstract:
Adult Polinices pulchellus were collected from the field and held in aquaria under ambient conditions. Egg collars laid by P. pulchellus were cultured at 14°C and 20°C and larval development after hatching was documented photographically. Planktotrophic Polinices pulchellus veligers hatched from egg collars cultured at 20°C after nine to ten days and after 14 to 15 days at 14°C. Veligers spent most of their time close to the water surface and began feeding within one hour of hatching. Repeated attempts to raise larvae to metamorphic competency at 14°C were unsuccessful. Morphological changes, most notably in the colour and size of the velum and foot, were observed in larvae raised at 20°C. During the first 25 days of larval development the velum broadened and bifurcated into four velar arms, the distal regions of which acquired a deep red coloration. By day 40 the foot had increased considerably in size and the degree of black pigmentation. By day 45 pediveligers were competent to metamorphose to the juvenile stage. Exposure to sediment from the adult habitat induced metamorphosis, larvae lost their vela and became benthic juveniles. Within three days of metamorphosis, juvenile snails drilled the bivalve Lasaea adansoni (∼2 mm), later drilled Cerastoderma edule (∼4 mm), and displayed cannibalistic behaviour. Larvae survived for ∼6 months in the absence of a suitable settlement cue.

Abstract:
As part of his recent study of ‘Narration and allusion in Archaic Greek Art’, Professor A. M. Snodgrass has cause to treat of the famous Attic black-figure vase which depicts Circe handing a cup containing her sinister brew to one of Odysseus’ sailors. She is stirring it with her wand the while, and yet this sailor, and three companions besides, have already been transformed into various animals (or at least his head, and their heads and arms have been). Professor Snodgrass has no difficulty in explaining the apparent simultaneity of separate events here and elsewhere on this vase-painting as relating to what he calls the ‘synoptic’ technique of early Greek Art, that familiar device whereby several successive episodes in a narrative are presented together within the same picture. And he is inclined towards a similar line of explanation as regards the partial transformation of Odysseus’ ἑταῖροι: the artist ‘wished to express the passage of time by indicating a half-way stage in the transformation’.

Abstract:
We investigated the possible role of environmental variables in determining body size within a complex of salamander species (Desmognathus quadramaculatus). We analyzed data generated from life-history studies on populations from throughout the range of this species complex. We incorporated an alternative-hypothesis framework (sensu Platt) to determine the better predictor of adult body size, age at maturity, or size at metamorphosis. We found that almost 90% of the variation in adult body size was explained by size at metamorphosis, which was determined by a combination of rate of larval growth and length of the larval period. Environmental temperature and moisture level were positively correlated with larval growth rate and length of the larval period, respectively. We propose a simple model of body-size evolution that incorporates both adaptive and plastic components. We suggest that the length of the larval period may adaptively respond to moisture-level predictability. In addition, we suggest that the response of the larval growth rate to temperature may be plastic. Because the selection pressure due to drying-induced mortality is pervasive among species of amphibians, it may have played a role in shaping body-size radiation in desmognathines as well as the ecological structure of Appalachian streamside communities.

Abstract:
Based on the plot of Swan Lake, Black Swan depicts an ingenue’s metamorphosis into a woman and a prima ballerina that contains a fairy-tale plot in which a naïve heroine overcomes enemies and obstacles in order to achieve success and sexual maturity. Unlike a traditional fairy tale, this cinematic tale concludes with death and the clear distinctions between good and evil, helper and adversary and reality vs. fantasy are fluid. As in many fairy tales, the film criticizes the values of its era, namely, the narcissistic aspects of contemporary society with its excessive worship of youth, beauty and celebrity, and its most pernicious results—escape into fantasy and insanity, aggressive rivalry, violence, and self-destruction.

Full text
Abstract:
This article attempts a womanist reading of Alice Walker’s The Color Purple. Walker provides a gendered perspective of what it means to be “black,” “ugly,” “poor,” and a “woman” in America. This perspective is ignored in the majority of male-authored African American texts that privilege race and class issues. Being “black,” “poor,” “ugly,” and a “woman,” underscores the complexity of the African American woman’s experience as it condemns African American women into invisibility. However, Walker’s characters like Celie, Sofia, Shug, Mary Agnes, and Nettie fight for visibility and assist each other as African American women in their quest for freedom and independence in a capitalist, patriarchal, and racially polarized America. This article therefore maps out Celie’s evolution from being a submissive and uneducated “nobody” (invisible/voiceless) to a mature and independent “someone” (visibility/having a voice). Two important womanist concepts namely “family” and “sisterhood” inform this metamorphosis as Walker underscores her commitment to the survival and wholeness of African American people.

Abstract:
Abstract Warning colouration reduces predation risk by signalling or mimicking the unpleasantness of prey and therefore increases survival. We tested in two experiments the evolutionary costs and benefits of the yellow colour pattern in fire salamanders (Salamandra salamandra), which display a yellow/black colour pattern usually associated with toxic alkaloids. Our first experiment aimed to test whether the development of colouration is condition dependent and thus related to developmental costs, i.e. influenced by resource availability during the developmental process. Therefore, we reared fire salamander larvae under different nutritional conditions and compared the relative amount of yellow they developed after metamorphosis. Fire salamander larvae reared under limited food conditions had a lower proportion of yellow following metamorphosis than control larvae reared under superior food conditions. In a second experiment we tested whether the proportion of yellow has an impact on the risk of being attacked using artificial models. We tested, in salamander-free and salamander-occupied natural habitats, whether artificial clay models with different proportions of yellow and black receive different attack rates from potential predators (birds, mammals, insects). In clay models the proportion of yellow and the site had a significant effect on predation risk. Models with larger amounts of yellow had fewer bite marks from predators such as carabid beetles and birds, but only in sympatry with salamanders. In conclusion, the early expression of conspicuous colouration seems to be condition dependent and therefore potentially costly. Furthermore, the yellow colouration of fire salamanders act as a signal that potentially reduces their risk of being attacked by predators. Thus, the yellow colouration of fire salamanders seems to represent an adaptive trait that reduces the risk of predation, which can be expressed in higher quantity by individuals of a certain condition.

Abstract:
This article aims to present the book-to-film metamorphosis of Grover Underwood from Rick Riordan’s novel The Lightning Thief (2005), adapted in 2010 by Chris Columbus for the screen. This character in both works is presented as an excluded member of the society: in the empirical world, as a disabled person, in the mythological one, as a satyr. What is more, in the motion picture, Grover, played by a Black actor, poses as an even more marginalised character, as a representative of a community discriminated in the USA. Therefore, the images of this character reflect the various levels of exclusion and show the ideological significance of a contemporary adaptation for the young audience. The comparative analysis is performed with the use of reception studies and critical race theory perspectives.

Abstract:
Engaging contemporaneous ideas about how environmental factors could alter the surface of the human body, Samson Occom and Phillis Wheatley use language emphasizing the ostensible malleability of physical characteristics—what I call a symbolics of metamorphosis—to depict the formation of racial identities. For Occom, the beliefs his Anglo- and Native American contemporaries held about the status of the “red” Indian enable him to challenge colonial society's contradictory Christian epistemology in his 1772 A Sermon, Preached at the Execution of Moses Paul, an Indian. In her 1773 Poems on Various Subjects, Religious and Moral, Wheatley fuses ancient mythological beliefs and natural-historical axioms about the production of poetic genius and dark skin to characterize the black poet as an inevitable outcome rather than an anomalous exception. Drawing on the late-eighteenth-century notion of transformable race, this essay posits a historically specific model of critical race theory for interpreting early American literatures.

Zootaxa 1526, no. 1 (July 12, 2007): 51–61. http://dx.doi.org/10.11646/zootaxa.1526.1.3.

Full text
Abstract:
A new goby, Coryphopterus kuna, is described from the Atlantic coasts of Panama and Mexico. The species is distinguished from other Coryphopterus spp. by the low median fin and pectoral fin ray counts and the morphology of the pelvic fin. The pelvic fins are fully joined with a rounded outline and have branched and longer innermost pelvic fin rays. There is no frenum connecting the two pelvic fin spines and the fin is heavily speckled with black spots in the male holotype. The late larval stage of C. kuna is identified by DNA sequence matching and is morphologically similar to other larval Coryphopterus spp. but has a distinct melanophore pattern. Examination of the otolith microstructure reveals a relatively long pelagic larval duration of 63 days with a narrowing of the later daily increments suggesting delayed metamorphosis. The species is the first vertebrate to include gene sequence barcoding under the Barcode of Life Data System (BOLD) in the species description.

Abstract:
This article makes historical sense of the recent signs of the metamorphosis of nationalism into nativism in Zimbabwe and South Africa. The central thesis of the article is that the resurgence of Afro-radicalism and nativism in post-settler and post-apartheid societies partly reflected deep-rooted antinomies of black liberation thought and partly current ideological conundrums linked to the limits of both the African national project and global liberal democracy. Dismissals and sententious approaches towards nativism do not help in understanding the current issues in Zimbabwe and South Africa. There is the need to revisit the issues of imaginings of the African liberation agenda together with issues of the resolution of the national question, teleology of the liberation, ownership of strategic resources, knowledge production, control of public discourse, imaginations of the nation and visions of citizenship and democracy. Making sense of nativism provides an oblique entry into an interrogation of the current status of the African national project in Zimbabwe and South Africa.

Abstract:
Dusky gopher frogs once existed throughout the states of Mississippi, Alabama and Louisiana. Presently, the USA Fish and Wildlife Service estimates that there are less than 100 frogs left in the wild, with almost all of these residing in a single pond in Mississippi, making the dusky gopher frog America's most endangered frog species. Their habitat has been threatened by residential and forestry development, as well as from fire suppression and the decline of gopher tortoises, whose burrows the frogs use for shelter. The USA Fish and Wildlife Service brought the first dusky gopher frogs into captivity in 2001 and they have been kept at the Memphis Zoo since 2003 and at Omaha's Henry Doorly Zoo since 2004. Natural breeding attempts in captivity have been unsuccessful despite efforts to artificially mimic what is known to be the appropriate seasonal environmental (e.g. light, humidity, temperature) and social cues (e.g. calls from wild frogs during the breeding season) that stimulate reproduction in situ. Also, there was a concern about the incidences of abnormalities (e.g. spindly legs) from inadequate husbandry conditions (e.g. nutritional deficiencies) or diseases in tadpoles and froglets produced ex situ (e.g. dermomycoides). The objectives of this study were (1) to examine the developmental competence of tadpoles produced by exogenous hormone treatment for IVF to complete normal metamorphosis into viable froglets ex situ and (2) to determine the incidence of developmental abnormalities or dermomycoides in the froglets produced ex situ. Males and females were first separated by the identification of black male nuptial pads used during amplexus. Males and females were stimulated to spermiate and ovulate, respectively, using a variation of a standard amphibian hormonal stimulation protocol (Kouba et al. 2012 Reprod. Fertil. Dev. 24). As a result, more than 1460 viable tadpoles (61% of fertilized eggs) were produced from 18 segregated genetic pairings. To date, 602 (41%) of the tadpoles have completed normal metamorphosis into viable froglets (over 6 times the known existing population in situ), 51% were either culled to examine for dermomycoides or died for a variety of known (accidental) and unknown reasons (abnormal appendage development accounting for less than 7%) and 8% have yet to metamorphose after 9 months. The incidence of dermomycoides in the culled individuals was 100%; however, a study being conducted concurrently in their native habitat has confirmed that the organism does exist in situ with the dusky gopher frogs, which act as natural carriers. Efforts are currently in place to establish reintroduction programs for the dusky gopher froglets produced ex situ to increase the dwindling wild population now that tadpoles produced by IVF have been shown to be developmentally competent. In conclusion, IVF can be used to produce tadpoles of the dusky gopher frog with a low incidence of abnormalities, but the tadpoles were found to be carriers of the organism dermomycoides similar to their counterparts in the wild.

Abstract:
Optical microscopy, electron microscopy and microspectrophotometry were used to characterize pigments in the eyes of planktonic larvae of two species of the lysiosquilloid stomatopod Pullosquilla, P. litoralis and P. thomassini, which live sympatrically in French Polynesia. In contrast to the adult retina, which contains a diverse assortment of visual pigments in the main rhabdoms, the principal photoreceptors throughout the larval eyes of both species were found to contain a single rhodopsin with an absorption maximum (<IMG src="/images/symbols/&lgr ;.gif" WIDTH="8" HEIGHT= "12" ALIGN="BOTTOM" NATURALSIZEFLAG="3">max) close to 446 nm. The expression of this visual pigment may survive metamorphosis, since several adult rhodopsins occur at a similar spectral position. The retinas of these planktonic larvae also contain a novel yellow photostable pigment, which is arrayed in a regular pattern at the distal margin of the larval retina. The absorption spectrum of this pigment is well matched to the larval rhodopsin, suggesting that it acts to screen the rhabdoms from stray light. By replacing opaque, black screening pigment, the transparent yellow pigment may act together with a blue iridescent layer in the larval retina to reduce the visual contrast of the larval eye against downwelling and sidewelling light, while simultaneously acting as a retinal screen.

Social vulnerability still affects many people, especially if there are no public policies on education, welfare, health and safety. It can have negative consequences both physical, and psychic. Amidst this scenario, it is clear that art can bring benefits to the individual. We chose to roost for this research to be a wide artistic expression, involving various expressions, as well as being one of the largest and oldest art forms in Brazil, with traces of the black community that was enslaved in colonial and imperial Brazil. This study aimed to understand how participation in the Santa Terezinha Foundation capoeira group in Pompey-EC Senator interfere in the construction of identity of adolescents in socially vulnerable. It is a country and qualitative research, as well as descriptive and exploratory, using case study. Data were collected in Santa Terezinha Foundation in Senador Pompeu, from March to May. Made use of questionnaire and semi-structured interviews conducted with 2 teenager’s capoeira group. Content analysis revealed categories like "Capoeira and its personal meaning", "capoeira teacher Meaning" and "Identity and (m) metamorphosis." It was noticed several positive changes in the lives of these subjects, where this article can be effective in targeted intervention practices for this audience, and demonstrate the importance of public policies that encourage the poultry, especially in unfavourable contexts and social vulnerability.

Abstract:
The influence of moderately diluted, agitated, i.e., homeopathically prepared, thyroxin solutions (10-11–10-12, final concentration in the basin water 0.6 × 10-15− 0.6 × 10-25parts by weight after the first application) on metamorphosis in highlandRana temporariafrom the two-legged stage was studied. In accordance with the homeopathic idea of effects of specially prepared dilutions being inverse to those of their mother substances, animals were treated either with thyroxin 10-11–10-21or analogously prepared blank solution (water). Development was monitored by documenting the number of animals that had entered the four-legged stage. It has been found that animals treated with the thyroxin solutions metamorphosed more slowly than the control animals, i.e., the effect of the homeopathically prepared thyroxin was opposed to the usual effect of molecular thyroxin. The number of test animals that reached the four-legged stage at defined points in time was smaller (2–13.5%) in the group treated with homeopathically prepared thyroxin at the points in time, compared to control. The results in this study sustain the previous multiresearcher findings that show that diluted homeopathically prepared thyroxin is able to slow down metamorphosis ofR. temporaria.

Abstract:
Ovidians today agree that humour is central to understanding the Metamorphoses; but much disagreement exists about what passages are funny; what type of humour is used; and what response it is intended to elicit. Since his own time Ovid's humour has provoked criticism: Quintilian and the two Senecas criticise him for introducing to the Metamorphoses an inappropriate tone. The Romantics found Ovid's humour in bad taste. For much of the 19th and 20th centuries it was taken to be light and on the surface. More recently scholars identify his humour as either deep and humane or hateful and misogynistic. This division is caused, in my opinion, by Ovid's black humour, which by its very nature is easily misunderstood or missed, especially by those inclined to see the tragic in things, disinclined to see comedy mixed into a scene of death or rape, inclined to think the tragic, serious and universal more worthy, profound and significant than the comic, base and particular.

Abstract:
The influence of a highly diluted agitated, i.e. homeopathically prepared thyroxin solution (10-30, final concentration in the basin water 10-35parts by weight after the first application) on metamorphosis in lowland Rana temporaria from the spawn stage on was studied. The treatment with homeopathically prepared thyroxin solution (10-30) starts at the frogspawn stage. It represents a tool to learn more about the previously standardized amphibian model, where the thyroxin solution was applied from the two- legged stage on only. Lowland frogs were pretreated by immersing spawn in an aqueous molecular thyroxin dilution (10-8parts by weight). In later stages of development (2 to 4 legged), this has been found to speed up metamorphosis by around 15%. In accordance with the homeopathic idea of detoxication or cure, hyperstimulated animals (spawn or, in subsequence, larvae) were treated either with thyroxin that had been highly diluted and agitated in successive steps, i.e. homeopathically prepared (10-30), or analogously prepared blank solution (water). Development was monitored by documenting the number of animals that had entered the four-legged stage. It has been found that animals treated with the test solution metamorphosed more slowly than the control animals, i.e. the effect of the homeopathically prepared thyroxin was opposed to the usual effect of molecular thyroxin. The number of test animals that reached the 4- legged stage at defined points in time was slightly smaller in the group treated with homeopathically prepared thyroxin at some, but not at all points in time, compared to control. The results in this study sustain the previous multi researcher findings that highly diluted homeopathically prepared thyroxin is able to slow down metamorphosis ofRana temporaria.

Full text
Abstract:
ABSTRACTCarboniferous sandstones from within the thermal aureoles of igneous intrusions in the Midland Valley of Scotland sometimes have a strong, black colour and are termed ‘black sandstones’. Tait (1926) concluded that the black sandstones are the products of the thermal metamorphism of petroliferous sandstones, a theory which is discussed here in the light of modern petrological and geochemical techniques.The black colour of the sandstones is due to an amorphous, opaque bitumen which usually coats illitic clays, fills porosity and was mostly emplaced at a fairly late diagenetic stage. This solid bitumen has a low reflectance (c. 0·15% R0), no fluorescence under blue-light excitation, is insoluble in organic solvents, is isotopically heavy and has a very low H/C atomic ratio. These data, together with the field relationships of the black sandstones and igneous intrusions, suggest that the bitumen was formed by the thermal alteration of hydrocarbons, as described by Tait (1926), rather than by other possible mechanisms such as the deasphalting of an oil, or the generation of hydrocarbons from organic-rich rocks heated by igneous intrusions, followed by fractionation during migration. This conclusion suggests that by the time of emplacement of the quartz-dolerite intrusions, and some of the alkali-dolerite sills, there had been widespread generation and migration of hydrocarbons which possibly could have been preserved to the present day where not thermally altered.

Full text
Abstract:
Nitric Oxide (NO) plays a key role in the induction of larval metamorphosis in several invertebrate phyla. The inhibition of the NO synthase in Crepidula fornicata, a molluscan model for evolutionary, developmental, and ecological research, has been demonstrated to block the initiation of metamorphosis highlighting that endogenous NO is crucial in the control of this developmental and morphological process. Nitric Oxide Synthase contributes to the development of shell gland, digestive gland and kidney, being expressed in cells that presumably correspond to FMRF-amide, serotoninergic and catecolaminergic neurons. Here we identified a single Nos gene in embryonic and larval transcriptomes of C. fornicata and studied its localization during development, through whole-mount in situ hybridization, in order to compare its expression pattern with that of other marine invertebrate animal models.

Full text
Abstract:
AbstractZincian högbomite (ZnO 3.5–10.5wt.%) occurs as an accessory phase in garnet quartzite that is intimately associated with the Broken Hill and Black Mountain Cu-Pb-Zn-Ag deposits, Aggeneys, South Africa. Högbomite coexists with a number of minerals including quartz, gahnite, sillimanite, sphalerite, pyrrhotine, pyrite, magnetite, and ilmenite, suggesting that högbomite may have formed by sulphidation and oxidation reactions. Such reactions may account for the high Zn content of högbomite. Where associated with metamorphosed massive sulphide deposits högbomite is enriched in Zn relative to that found in ultramafics, Fe-Ti deposits, Fe ores, aluminous metasediments, and skarns. This enrichment in högbomite constitutes a potential exploration guide for metamorphosed massive sulphide deposits.

Abstract:
A pulse of the steroid hormone ecdysone triggers the destruction of larval salivary glands during Drosophila metamorphosis through a transcriptional cascade that converges on reaper (rpr) and head involution defective (hid) induction, resulting in caspase activation and cell death. We identify the CREB binding protein (CBP) transcriptional cofactor as essential for salivary gland cell death. We show that CBP acts 1 d before the onset of metamorphosis in apparent response to a mid-third instar ecdysone pulse, when CBP is necessary and sufficient for down-regulation of the Drosophila inhibitor of apoptosis 1 (DIAP1). It is only after DIAP1 levels are reduced that salivary glands become competent to die through rpr/hid-mediated cell death. Before this time, high levels of DIAP1 block salivary gland cell death, even in the presence of ectopic rpr expression. This study shows that naturally occurring changes in inhibitor of apoptosis levels can be critical for regulating cell death during development. It also provides a molecular mechanism for the acquisition of competence in steroid signaling pathways.

Abstract:
This text is a hermeneutic exercise about one of the paradigmatic works of Vinicius de Moraes, Orfeu da Conceição. This plays opens a partnership between the poet and the composer Antonio Carlos Jobim, which was fruitful and unique for Brazilian arts. Orfeu da Conceição is also paradigmatic because it is the first work to bring black actors to the stages of the Municipal Theater of Rio de Janeiro. Orfeu da Conceição led to one of the films that most contributed, positively or negatively, to the international image of Brazil in the second half of the 20th century, the award-winning Orpheus Negro, by Marcel Camus. The text will notice how many of the ideas and representations of the favela were already visible in the Brazilian popular repertoire prior to the composition of the play. The idea, in general, is to observe how, in addition to its poetic-musical quality, Orfeu da Conceição can also serve as a reflection on how we represent and see favelas in the urban context, both in 1956 and today.

Abstract:
The central concept of the article is performance as a form of expression specific to non-normative people. In confrontation with the oppressive discourse of dominant groups, the body of an excluded individual and its metamorphoses in themselves appear to be an alternative way of non-alienated expression. This phenomenon is discussed via the example of the practices of New York’s ballroom culture — primarily via the example of the film Paris is Burning from 1990, directed by Jennie Livingston. In the ballroom community, black and non-heteronormative Americans found a safe space for experiments with their identity, thanks to which they could experience a form of capitalistic success through an ephemeral performance. However, these practices, despite their apparent subversiveness and emancipatory potential, did not have the ambition to change the status quo. They only allowed experiencing the feeling of social advancement within the existing system. The story that ballroom culture members in the 1980s told about themselves through their own performances was part of a unique, non-verbal discourse of excluded groups, which developed a specific communication code based on the human body, its ways of moving and its aesthetic metamorphoses.

Full text
Abstract:
Late Cretaceous–Early Eocene Tethyan evolution of western Turkey is characterized by ophiolite obduction, high-pressure/low-temperature metamorphism, subduction, arc magmatism and continent–continent collision. The imprints of these events in the Upper Cretaceous–Lower Eocene sedimentary record of western Anatolia are studied in thirty-eight well-described stratigraphic sections. During the Late Cretaceous period, western Turkey consisted of two continents, the Pontides in the north and the Anatolide-Taurides in the south. These continental masses were separated by the İzmir-Ankara Neo-Tethyan ocean. During the convergence the Pontides formed the upper plate, the Anatolide-Taurides the lower plate. The arc magmatism in the Pontides along the Black Sea coast is biostratigraphically tightly constrained in time between the late Turonian and latest Campanian. Ophiolite obduction over the passive margin of the Anatolide-Tauride Block started in the Santonian soon after the inception of subduction in the Turonian. As a result, large areas of the Anatolide-Tauride Block subsided and became a region of pelagic carbonate sedimentation during the Campanian. The leading margin of the Anatolide-Tauride Block was buried deeply and was deformed and metamorphosed to blueschist facies during Campanian times. The Campanian arc volcanic rocks in the Pontides are conformably overlain by shaley limestone of Maastrichtian–Palaeocene age. However, Maastrichtian sedimentary sequences north of the Tethyan suture are of fore-arc type suggesting that although arc magmatism ceased by the end of the Campanian age, continent–continent collision was delayed until Palaeocene time, when there was a change from marine to continental sedimentation in the fore-arc basins. The interval between the end of the arc magmatism and continent–continent collision may have been related to a northward jump of the subduction zone at the end of Campanian time, or to continued obduction during the Maastrichtian.

Abstract:
On 25 May 2020, the death of an unknown Blackman named George Floyd in the Minneapolis United States has led to a wave of global protests worldwide. The United Kingdom was not left out of these protests. The deaths of black people in police custody are not a new unfortunate phenomenon in the United Kingdom. The author looks at some of these deaths in the United Kingdom from a historical perspective, relying on both racial typologies theorists on one side and the responses, provided by Afrocentric theorists on race over time, on the other side. The author relies on several case studies of black deaths and secondary sources, arguing that racism can be held responsible for most of these killings by the police. The research findings are encapsulated in the trio unfortunate incidents of slavery, colonialism, and apartheid. These incidences have metamorphosed over time, becoming a social stigma black people wear from cradle to grave. The author suggests that police officers who murder black people and hide behind the wearing of uniforms should not be given immunity from justice. The author debunks the myth, suggesting that the life of a black person is often portrayed as worthless by whites folks. More findings are that both black lives and every human being's lives matter with great intrinsic value. No life must be wasted under the guise of policing. The right to life unarguably remains the most fundamental human right, which the state must protect at all times. Without the protection of life, all other fundamental human rights become meaningless.

Abstract:
Abstract Hornfels from the closed “Wolność” mine (Kowary, the Lower Silesia) are recognized as thermally metamorphosed rocks belonging to hornblende-hornfels facies or locally a facies of pyroxene hornfels. Their texture reveal the traces of some deformations such as folding or fractures. Their protholit is described as a pelitic deposit enriched with clay minerals. The sediment was altered into meta-pelities-aleurites after the diagenesis, and later the rock was intensely thermally metamorphosed at the contact with the intrusion of the Karkonosze granitoid. Three varieties are distinguished based on their colour: green, grey and black. Green and black colours result from the predominance of hornblende and biotite over other rock components, respectively. Whereas grey hornfels are composed of similar amounts of both mafic minerals: biotite and hornblende. Quartz, mica minerals (biotite and muscovite), amphibole, (hornblende), acid plagioclase and andalusite, epidote group (clinozoisite), orthoclase and pyroxene make up hornfels components. Locally, andalusite is accompanied by sillimianite, which indicates a higher degree of contact metamorphism alterations. Three generations of minerals are distinguished in the rocks: allogenic (I), metamorphic (II) and hydrothermal (III). The allogenic phases are represented by heavy minerals such as zircon, apatite and monazite, which are characteristic of the protholit. The main components of the rocks (e.g. quartz, hornblende, feldspars, andalusite, sillimanite, mica minerals) belong to metamorphic minerals. Chalcopyrite, pyrite and fluorite are surely hydrothermally originated phases. Granitoides found at the contact zone with hornfels indicate traces of metasomatic alteration as a result of endomorphism in this region.

Abstract:
The article deals with the issue of African American identity in the post-segregation period (after 1968). The problem of African Americans’ “double consciousness”, marked for the first time yet in the late 19th – early 20th century, still remains relevant. It is that descendants of slaves, who over the centuries have been relegated to the periphery of the American society, have been experiencing and in part are experiencing an internal conflict, caused by the presence of both American and African components in their identities. The authors focus on Afrocentrism (Afrocentricity) – a socio-cultural theory, proposed by Molefi Kete Asante in 1980 as a strategy to overcome this conflict and to construct a particular form of “African” collective identity of African Americans. This theory, based on the idea of Africa and all people of African descent’s centrality in world history and culture, was urged to completely decolonize and transform African Americans’ consciousness. The Afrocentrists proposed African Americans to re- Africanize their self-consciousness, turn to African cultural roots in order to get rid of a heritable inferiority complex formed by slavery and segregation. This article presents a brief outline of the history of Afrocentrism, its intellectual sources and essential structural elements, particularly Africology. The authors analyze the concepts of racial identity, “black consciousness” and “black unity” in the contexts of the Afrocentric theory and current social realities of the African American community. Special attention is paid to the methodology and practice of Afrocentric education. In Conclusion, the authors evaluate the role and prospects of Afrocentrism among African Americans in the context of general trends of their identities transformations.

Abstract:
AbstractTwo types of metasedimentary rocks occur in the Trans-North China Orogen of the North China Craton. One type consists of highly metamorphosed supracrustal rocks with protoliths of mature cratonic shale, called khondalites, as found in the Lüliang Complex; rocks of the other type are also highly metamorphosed but less mature, as represented by the Wanzi supracrustal assemblage in the Fuping Complex. U–Pb isotopic data for detrital zircons from khondalites show a provenance dominated by 1.9–2.1 Ga Palaeoproterozoic rocks. These detrital zircons display a wide range of εHfvalues from −16.0 to +9.2 and give Hf isotopic model ages mostly around 2.3 Ga. The high positive εHfvalues approach those for the depleted mantle at 2.1 Ga, highlighting a juvenile crustal growth event in Palaeoproterozoic times. Hf isotopic data also imply thatc.2.6 Ga old crustal material was involved in the Palaeoproterozoic magmatic event. These data are similar to those for the khondalitic rocks from the interior of the Western Block of the North China Craton, suggesting a common provenance. In contrast, other metasedimentary rocks in the Trans-North China Orogen, such as the Wanzi supracrustal assemblage in the Fuping Complex, have a source region with both Palaeoproterozoic and Archaean rocks. Their detrital zircon Hf isotopic data indicate reworking of old crustal material and a lack of significant juvenile Palaeoproterozoic magmatic input. These rocks are similar to the coevally deposited meta-sedimentary rocks in the interior of the Eastern Block. We propose that the Lüliang khondalites were deposited on the eastern margin of the Western Block in a passive continental margin environment and were thrust eastward later during collision with the Eastern Block. Other metasedimentary rocks in the Trans-North China Orogen were deposited on the western margin of the Eastern Block in a continental arc environment. Our data support the eastward subduction model for the Palaeoproterozoic tectonic evolution of the North China Craton.

Abstract:
The Upper Silesian and Małopolska blocks are situated near the southwestern boundary of the East European Platform within the Trans-European Suture Zone. The Lower Palaeozoic lithologies of the blocks reveal different stratigraphic and diastrophic development. In the Upper Silesian Block, unmetamorphosed and gently folded Lower Cambrian to Ordovician sedimentary rocks rest on a Cadomian basement. The Lower Cambrian is represented by an older (sub-Holmia) Borzęta Formation and a younger (Holmia) Goczałkowice Formation. The thickness of the Cambrian lithologies increases from the southwest towards the lateral part of the block. In the Małopolska Block Palaeozoic and Precambrian lithologies are represented by regionally metamorphosed and intensely folded Lower Cambrian–Vendian clastic rocks which are unconformably overlain by Ordovician–Lower Silurian carbonates and Upper Silurian clastic rocks. The crystalline basement of the Małopolska Block has yet to be recognized. The Lower Palaeozoic sediments of both blocks are overlain by Devonian and Carboniferous rocks. The blocks are in direct contact along a narrow tectonic zone, a part of the largely concealed Hamburg–Kraków fault zone, in which tectonic evolution has taken place spasmodically with strike-slip movements predominating.
