Academic literature on the topic '120199 Architecture not elsewhere classified'

Two cult structures from Mycenae and from a sanctuary recently discovered at Phylakopi, on the island of Melos, shed a new light on the sacred architecture of the Aegean at the close of the Bronze Age. This paper suggests that the edifices of both these sites should be classified as popular places of worship. This suggestion is based on their location, layout and size as well as on their foreign architectural affinities. The Phylakopi sanctuary, located against the fortification wall of the town, consists of a major temple to which a subsidiary shrine is attached. The pair of adjacent structures located on the lower terrace of the acropolis of Mycenae, are of approximately the same size, presumably possessing the same religious status. The three edifices bear several asymmetrical features, such as indirect entrances and corner platforms that have no parallels elsewhere in the Aegean. These features are diagnostic to a special type of Canaanite temples that prevailed in maritime posts and harbour sites. There are indications, however, that in spite of the foreign architectural affinities, the cult practised in the Mycenae structures and in the major temple of Phylakopi was distinctively Aegean. On the other hand, architectural and contextual data seem to support the assumption that the subsidiary shrine of Phylakopi was reserved for foreign cult, practised by Canaanite traders.

ObjectiveEmbryonal tumors with multilayered rosettes (ETMRs) are a histologically heterogeneous entity and gather embryonal tumors with abundant neuropil and true rosettes (ETANTRs), ependymoblastoma, and medulloepithelioma. ETMRs are highly aggressive and associated with poorer clinical courses. However, cases of this entity are rare, and advances in molecular genetics and therapy are minor. The purpose of our study was to retrospectively analyze the clinical, pathological features, and prognostic factors of ETMRs.MethodsOur cohort consisted of 17 patients diagnosed with ETMRs in our hospital from 2018 to 2022, and two of them were lost to follow-up. Clinical data were retrieved, and immunohistochemistry and genetic analyses were performed.ResultsAmong 17 cases, 16 were ETANTRs, and one was medulloepithelioma. Morphologically, tumor cells of ETANTRs could transform into anaplasia and lose the biphasic architecture during tumor progression. Immunohistochemistry of LIN28A revealed positive expression in 17 cases, and the expression of LIN28A was more intense and diffuse in the recurrent lesions than in primaries. The increased N-MYC copy numbers were detected in the primary tumor and recurrence of patient 8. Moreover, the incidence of metastatic disease was 100% in patients aged > 4 years and 18% in the younger group. For patients receiving chemotherapy, the median overall survival time was 7.4 months, while that of those who didn’t receive it was 1.2 months. Nevertheless, surgical approaches, radiotherapy, age at presentation, gender, tumor location, and metastatic status were not associated with independent prognosis.ConclusionETANTR might not present as the typical morphologies during tumor progression, so analyses of C19MC amplification and Lin28A antibody are indispensable for diagnosing ETMRs accurately. Children aged > 4 years tend to have a higher rate of metastasis in ETMRs. Chemotherapy is the only prognostic factor for ETMRs patients with a favorable prognosis. The biological nature and clinical patterns for recurrent diseases need to be further demonstrated to predict prognosis and guide treatment.

This paper argues that artist Dope Saint Jude is transforming South African hip-hop by queering a genre that has predominantly been male and heteronormative. Specifically, I analyse the opening skit of her music video “Keep in Touch” in order to unpack the ways which she revives Gayle, a gay language that adopted double-coded forms of speech during the apartheid era—a context in which homosexuals were criminalised. The use of Gayle and spaces close to the city centre of Cape Town (such as Salt River and Woodstock) speaks to the city as it was before it was transformed by the decline of industries due to the country’s adoption of neoliberal economics and, more recently, by the gentrification of these spaces. Dope Saint Jude therefore reclaims these city spaces through her use of gay modes of speech that have a long history in Cape Town and by positioning her work as hip-hop, which has been popular in the city for well over two decades. Her inclusion of transgender MC and DJ Angel Ho pushes the boundaries of hegemonic and binary conceptions of gender identity even further. In essence, Dope Saint Jude is transforming local hip-hop in a context that is shaped significantly by US cultural imperialism. The artist is also transforming our perspective of spaces that have been altered by neoliberal economics.Setting the SceneDope Saint Jude (DSJ) is a queer MC from Elsies River, a working class township located on Cape Town's Cape Flats in South Africa. Elsies River was defined as a “coloured” neighbourhood under the apartheid state's Group Areas Act, which segregated South Africans racially. With the aid of the Population Registration Act, citizens were classified, not merely along the lines of white, Asian, or black—black subjects were also divided into further categories. The apartheid state also distinguished between black and “coloured” subjects. Michael MacDonald contends that segregation “ordained blacks to be inferior to whites; apartheid cast them to be indelibly different” (11). Apartheid declared “African claims in South Africa to be inferior to white claims” and effectively claimed that black subjects “belonged elsewhere, in societies of their own, because their race was different” (ibid). The term “coloured” defined people as “mixed race” to separate communities that might otherwise have identified as black in the broad and inclusive sense (Erasmus 16). Racial categorisation was used to create a racial hierarchy with white subjects at the top of that hierarchy and those classified as black receiving the least resources and benefits. This frustrated attempts to establish broad alliances of black struggles against apartheid. It is in this sense that race is socially and politically constructed and continues to have currency, despite the fact that biologically essentialist understandings of race have been discredited (Yudell 13–14). Thanks to apartheid town planning and resource allocation, many townships on the Cape Flats were poverty-stricken and plagued by gang violence (Salo 363). This continues to be the case because post-apartheid South Africa's embrace of neoliberal economics failed to address racialised class inequalities significantly (Haupt, Static 6–8). This is the '90s context in which socially conscious hip-hop crews, such as Prophets of da City or Black Noise, came together. They drew inspiration from Black Consciousness philosophy via their exposure to US hip-hop crews such as Public Enemy in order to challenge apartheid policies, including their racial interpellation as “coloured” as distinct from the more inclusive category, black (Haupt, “Black Thing” 178). Prophets of da City—whose co-founding member, Shaheen Ariefdien, also lived in Elsies River—was the first South African hip-hop outfit to record an album. Whilst much of their work was performed in English, they quickly transformed the genre by rapping in non-standard varieties of Afrikaans and by including MCs who rap in African languages (ibid). They therefore succeeded in addressing key issues related to race, language, and class disparities in relation to South Africa's transition to democracy (Haupt, “Black Thing”; Haupt, Stealing Empire). However, as is the case with mainstream US hip-hop, specifically gangsta rap (Clay 149), South African hip-hop has been largely dominated by heterosexual men. This includes the more commercial hip-hop scene, which is largely perceived to be located in Johannesburg, where male MCs like AKA and Cassper Nyovest became celebrities. However, certain female MCs have claimed the genre, notably EJ von Lyrik and Burni Aman who are formerly of Godessa, the first female hip-hop crew to record and perform locally and internationally (Haupt, Stealing Empire 166; Haupt, “Can a Woman in Hip-Hop”). DSJ therefore presents the exception to a largely heteronormative and male-dominated South African music industry and hip-hop scene as she transforms it with her queer politics. While queer hip-hop is not new in the US (Pabón and Smalls), this is new territory for South Africa. Writing about the US MC Jean Grae in the context of a “male-dominated music industry and genre,” Shanté Paradigm Smalls contends,Heteronormativity blocks the materiality of the experiences of Black people. Yet, many Black people strive for a heteronormative effect if not “reality”. In hip hop, there is a particular emphasis on maintaining the rigidity of categories, even if those categories fail [sic]. (87) DSJ challenges these rigid categories. Keep in TouchDSJ's most visible entry onto the media landscape to date has been her appearance in an H&M recycling campaign with British Sri Lankan artist MIA (H&M), some fashion shoots, her new EP—Reimagine (Dope Saint Jude)—and recent Finnish, US and French tours as well as her YouTube channel, which features her music videos. As the characters’ theatrical costumes suggest, “Keep in Touch” is possibly the most camp and playful music video she has produced. It commences somewhat comically with Dope Saint Jude walking down Salt River main road to a public telephone, where she and a young woman in pig tails exchange dirty looks. Salt River is located at the foot of Devil's Peak not far from Cape Town's CBD. Many factories were located there, but the area is also surrounded by low-income housing, which was designated a “coloured” area under apartheid. After apartheid, neighbourhoods such as Salt River, Woodstock, and the Bo-Kaap became increasingly gentrified and, instead of becoming more inclusive, many parts of Cape Town continued to be influenced by policies that enable racialised inequalities. Dope Saint Jude calls Angel Ho: DSJ: Awêh, Angie! Yoh, you must check this kak sturvy girl here by the pay phone. [Turns to the girl, who walks away as she bursts a chewing gum bubble.] Ja, you better keep in touch. Anyway, listen here, what are you wys?Angel Ho: Ah, just at the salon getting my hair did. What's good? DSJ: Wanna catch on kak today?Angel Ho: Yes, honey. But, first, let me Gayle you this. By the jol by the art gallery, this Wendy, nuh. This Wendy tapped me on the shoulder and wys me, “This is a place of decorum.”DSJ: What did she wys?Angel Ho: De-corum. She basically told me this is not your house. DSJ: I know you told that girl to keep in touch!Angel Ho: Yes, Mama! I'm Paula, I told that bitch, “Keep in touch!” [Points index finger in the air.](Saint Jude, Dope, “Keep in Touch”)Angel Ho's name is a play on the male name Angelo and refers to the trope of the ho (whore) in gangsta rap lyrics and in music videos that present objectified women as secondary to male, heterosexual narratives (Sharpley-Whiting 23; Collins 27). The queering of Angelo, along with Angel Ho’s non-binary styling in terms of hair, make-up, and attire, appropriates a heterosexist, sexualised stereotype of women in order to create room for a gender identity that operates beyond heteronormative male-female binaries. Angel Ho’s location in a hair salon also speaks to stereotypical associations of salons with women and gay subjects. In a discussion of gender stereotypes about hair salons, Kristen Barber argues that beauty work has traditionally been “associated with women and with gay men” and that “the body beautiful has been tightly linked to the concept of femininity” (455–56). During the telephonic exchange, Angel Ho and Dope Saint Jude code-switch between standard and non-standard varieties of English and Afrikaans, as the opening appellation, “Awêh,” suggests. In this context, the term is a friendly greeting, which intimates solidarity. “Sturvy” means pretentious, whilst “kak” means shit, but here it is used to qualify “sturvy” and means that the girl at the pay phone is very pretentious or “full of airs.” To be “wys” means to be wise, but it can also mean that you are showing someone something or educating them. The meanings of these terms shift, depending on the context. The language practices in this skit are in line with the work of earlier hip-hop crews, such as Prophets of da City and Brasse vannie Kaap, to validate black, multilingual forms of speech and expression that challenge the linguistic imperialism of standard English and Afrikaans in South Africa, which has eleven official languages (Haupt, “Black Thing”; Haupt, Stealing Empire; Williams). Henry Louis Gates’s research on African American speech varieties and literary practices emerging from the repressive context of slavery is essential to understanding hip-hop’s language politics. Hip-hop artists' multilingual wordplay creates parallel discursive universes that operate both on the syntagmatic axis of meaning-making and the paradigmatic axis (Gates 49; Haupt, “Stealing Empire” 76–77). Historically, these discursive universes were those of the slave masters and the slaves, respectively. While white hegemonic meanings are produced on the syntagmatic axis (which is ordered and linear), black modes of speech as seen in hip-hop word play operate on the paradigmatic axis, which is connotative and non-linear (ibid). Distinguishing between Signifyin(g) / Signification (upper case, meaning black expression) and signification (lower case, meaning white dominant expression), he argues that “the signifier ‘Signification’ has remained identical in spelling to its white counterpart to demonstrate [. . .] that a simultaneous, but negated, parallel discursive (ontological, political) universe exists within the larger white discursive universe” (Gates 49). The meanings of terms and expressions can change, depending on the context and manner in which they are used. It is therefore the shared experiences of speech communities (such as slavery or racist/sexist oppression) that determine the negotiated meanings of certain forms of expression. Gayle as a Parallel Discursive UniverseDSJ and Angel Ho's performance of Gayle takes these linguistic practices further. Viewers are offered points of entry into Gayle via the music video’s subtitles. We learn that Wendy is code for a white person and that to keep in touch means exactly the opposite. Saint Jude explains that Gayle is a very fun queer language that was used to kind of mask what people were saying [. . .] It hides meanings and it makes use of women's names [. . . .] But the thing about Gayle is it's constantly changing [. . .] So everywhere you go, you kind of have to pick it up according to the context that you're in. (Ovens, Saint Jude and Haupt)According to Kathryn Luyt, “Gayle originated as Moffietaal [gay language] in the coloured gay drag culture of the Western Cape as a form of slang amongst Afrikaans-speakers which over time, grew into a stylect used by gay English and Afrikaans-speakers across South Africa” (Luyt 8; Cage 4). Given that the apartheid state criminalised homosexuals, Gayle was coded to evade detection and to seek out other members of this speech community (Luyt 8). Luyt qualifies the term “language” by arguing, “The term ‘language’ here, is used not as a constructed language with its own grammar, syntax, morphology and phonology, but in the same way as linguists would discuss women’s language, as a way of speaking, a kind of sociolect” (Luyt 8; Cage 1). However, the double-coded nature of Gayle allows one to think of it as creating a parallel discursive universe as Gates describes it (49). Whereas African American and Cape Flats discursive practices function parallel to white, hegemonic discourses, gay modes of speech run parallel to heteronormative communication. Exclusion and MicroaggressionsThe skit brings both discursive practices into play by creating room for one to consider that DSJ queers a male-dominated genre that is shaped by US cultural imperialism (Haupt, Stealing Empire 166) as a way of speaking back to intersectional forms of marginalisation (Crenshaw 1244), which are created by “white supremacist capitalist patriarchy” (hooks 116). This is significant in South Africa where “curative rape” of lesbians and other forms of homophobic violence are prominent (cf. Gqola; Hames; Msibi). Angel Ho's anecdote conveys a sense of the extent to which black individuals are subject to scrutiny. Ho's interpretation of the claim that the gallery “is a place of decorum” is correct: it is not Ho's house. Black queer subjects are not meant to feel at home or feel a sense of ownership. This functions as a racial microaggression: “subtle insults (verbal, nonverbal, and/or visual) directed toward people of color, often automatically or unconsciously” (Solorzano, Ceja, and Yosso 60). This speaks to DSJ's use of Salt River, Woodstock, and Bo-Kaap for the music video, which features black queer bodies in performance—all of these spaces are being gentrified, effectively pushing working class people of colour out of the city (cf. Didier, Morange, and Peyroux; Lemanski). Gustav Visser explains that gentrification has come to mean a unit-by-unit acquisition of housing which replaces low-income residents with high-income residents, and which occurs independent of the structural condition, architecture, tenure or original cost level of the housing (although it is usually renovated for or by the new occupiers). (81–82) In South Africa this inequity plays out along racial lines because its neoliberal economic policies created a small black elite without improving the lives of the black working class. Instead, the “new African bourgeoisie, because it shares racial identities with the bulk of the poor and class interests with white economic elites, is in position to mediate the reinforcing cleavages between rich whites and poor blacks without having to make more radical changes” (MacDonald 158). In a news article about a working class Salt River family of colour’s battle against an eviction, Christine Hogg explains, “Gentrification often means the poor are displaced as the rich move in or buildings are upgraded by new businesses. In Woodstock and Salt River both are happening at a pace.” Angel Ho’s anecdote, as told from a Woodstock hair salon, conveys a sense of what Woodstock’s transformation from a coloured, working class Group Area to an upmarket, trendy, and arty space would mean for people of colour, including black, queer subjects. One could argue that this reading of the video is undermined by DSJ’s work with global brand H&M. Was she was snared by neoliberal economics? Perhaps, but one response is that the seeds of any subculture’s commercial co-option lie in the fact it speaks through commodities (for example clothing, make-up, CDs, vinyl, or iTunes / mp3 downloads (Hebdige 95; Haupt, Stealing Empire 144–45). Subcultures have a window period in which to challenge hegemonic ideologies before they are delegitimated or commercially co-opted. Hardt and Negri contend that the means that extend the reach of corporate globalisation could be used to challenge it from within it (44–46; Haupt, Stealing Empire 26). DSJ utilises her H&M work, social media, the hip-hop genre, and international networks to exploit that window period to help mainstream black queer identity politics.ConclusionDSJ speaks back to processes of exclusion from the city, which was transformed by apartheid and, more recently, gentrification, by claiming it as a creative and playful space for queer subjects of colour. She uses Gayle to lay claim to the city as it has a long history in Cape Town. In fact, she says that she is not reviving Gayle, but is simply “putting it on a bigger platform” (Ovens, Saint Jude, and Haupt). The use of subtitles in the video suggests that she wants to mainstream queer identity politics. Saint Jude also transforms hip-hop heteronormativity by queering the genre and by locating her work within the history of Cape hip-hop’s multilingual wordplay.

There is need for sustainable building practice in Nigeria as buildings generally show signs of poor design for ventilation, natural lighting, energy management, water management, waste management and other building services. These buildings under perform in relation to the purpose for which they have been built. Building users often complain that the buildings do not provide the required services such as functioning air-conditioning systems, effective water and energy management systems and waste management. Facilities management (FM) professionals in Nigeria have recognised the role that they can play in the practice of sustainable building as a way to proffering a solution to the above mentioned problems. Six objectives were set for the study: to identify the constituents of sustainable building with reference to literature and internationally recognised standards; to evaluate the role of FM in relation to the sustainable building at the design, the construction and operations stages of the building life-cycle; to develop a conceptual framework that shows the facilities manager’s role in sustainable buildings; to evaluate the perception of facilities managers in relation to their competence in achieving sustainable buildings; to investigate the drivers and barriers to the facilities manager’s role in achieving sustainable buildings; and finally to develop and validate a framework for sustainable building practice for FM in Nigeria. The methodology adopted for this research included a combination of extensive literature review, content analysis of relevant literature and documents, 20 interviews and a questionnaire survey of 139 members of IFMA Nigeria in order to identify sustainable building constituents and the facilities manager’s role in sustainable buildings. The findings of the research helped in developing a framework for the achievement of sustainable buildings through the facilities manager’s role at the design, construction and operations stages of the building’s life-cycle.

Murals have been the formal visual interpretation of the cultural, social and political life of all ages. Throughout they have been consistently combined with their architectural setting, for example, in ancient Egyptian tombs, in Renaissance churches and on the external walls of buildings in Mexico in the twentieth century. This is a central feature of mural painting. However many contemporary murals do not integrate with their architectural settings, in other words, do not fulfil the site-specificity of the architectural spaces for which they were made. This means that the most important aspect that distinguishes murals from other types of painting is absent. I studied and analysed a number of murals produced in the Italian Renaissance, Baroque and Rococo as this particular period is considered to be not only one of the most significant in the history of art but also a period in which painting and architecture were very closely allied as practices. In particular the radical developments in painting of pictorial space took place along side the developments in architecture. I argue that Renaissance murals could be described, using the terminology of contemporary art, as site-specific art. By identifying the relationship between pictorial space, architectural space and compositional structure I was able to test, through my own practice, the importance of these relationships in understanding the site-specificity of the compositional structure of murals. To address the issue of sitespecificity in murals, I investigated and developed a set of compositional structures through my mural practice that could be applied in the design, execution, and teaching of contemporary mural design. I have developed the notion of a deconstructive method of mural design in which the illusory space of the mural derives its compositional structure from the architectural space in which it sited. I have applied it, tested it and refined it through the execution of a number of hypothetical and live mural commissions. I believe that the approach to the study and practice of mural design I have developed from the perspective of a practice lead researcher contributes to the furtherance of mural design as both a profession and field of study. In particular the identification of compositional structures in mural design and the proposal of a deconstructive method contributes to our understanding of what a mural is as well as current notions of site-specificity in contemporary art.

Effective collaboration in a team is a crucial skill. When people interact together to perform physical tasks, they rely on gestures to convey instructions. This thesis explores gestures as means to assess physical collaborative task understanding. This research proposes a framework to represent, compare, and assess gestures’ morphology, semantics, and pragmatics, as opposed to traditional approaches that rely mostly on the gestures’ physical appearance. By leveraging this framework, functionally equivalent gestures can be identified and compared. In addition, a metric to assess the quality of assimilation of physical instructions is computed from gesture matchings, which acts as a proxy metric for task understanding based on gestural analysis. The correlations between this proposed metric and three other task understanding proxy metrics were obtained. Our framework was evaluated through three user studies in which participants completed shared tasks remotely: block assembly, origami, and ultrasound training. The results indicate that the proposed metric acts as a good estimator for task understanding. Moreover, this metric provides task understanding insights in scenarios where other proxy metrics show inconsistencies. Thereby, the approach presented in this research acts as a first step towards assessing task understanding in physical collaborative scenarios through the analysis of gestures.

Articular cartilage functions successfully as a compression load-bearing tissue by virtue of the functional interplay between a 3-dimensional structure of collagen fibrils and the entrapped water-swollen proteoglycan molecules. Crucial to this entrapment process is a mechanism or set of mechanisms that maintain the collagen fibrils in a finely divided interconnected configuration that immobilises the macro-molecular proteoglycan complexes. Any loss of interconnectivity in the collagen network that might reduce the constraints on the swelling tendency of the proteoglycan domains will lead to a lower matrix stiffness. There are some structural similarities between this less stiff or abnormally softened cartilage and the degenerative osteoarthritic matrix, although ultrastructural studies to date are somewhat limited. The primary objective of the research reported in this thesis was to investigate the fibrillar architecture in the general matrix of both the normal and abnormally softened cartilage matrices. The fibrillar architectures of the normal and abnormally softened general matrices were compared using Nomarski light microscopy (LM), transmission electron microscopy (TEM) with combined stereoscopic reconstruction, and scanning electron microscopy (SEM). As reported earlier by Broom (1984b), a pseudo-random network developed from an overall radial arrangement of collagen fibrils is the most fundamental ultrastructural characteristic of the normal general matrix. By contrast, this present investigation has shown that the most distinctive feature of the softened matrix is the presence of parallel and relatively unentwined fibrils, strongly aligned in the radial direction. A structural model illustrating the transformation from the normal to the softened matrix is proposed based on the important property of lateral interconnectivity in the fibrils which involves both entwinement and non-entwinement based interactions. The distribution of proteoglycans in the normal and the softened matrix was compared. The distribution of Type II collagen was investigated using immunohistochemical staining combined with confocal imaging. It is concluded that the Type II fibrils do persist in the altered matrix thus adding further experimental support for the proposed transformation model. The swelling behaviour of the general matrix of both normal and abnormally softened articular cartilage was compared by subjecting tissue specimens under different modes of constraint to a high swelling bathing solution of distilled water and comparing structural changes imaged at the macroscopic, microscopic and ultramicroscopic levels of resolution. Near-zero swelling was observed in the isolated normal general matrix with minimal structural change. By contrast, the similarly isolated softened general matrix exhibited large-scale swelling in both the transverse and radial directions. This difference in dimensional stability was attributed to fundamentally different levels of fibril interconnectivity between the two matrices. The structural transformation model was further developed to accommodate fibrillar rearrangements associated with the large-scale swelling in the radial and transverse directions in the softened general matrix.
