This symbol system was directly conveyed by a series medley shape signs, many-faceted color signs and decorated craft signs of pleated skirt. Its origination, accumulation, continual process and development were greatly associated with the life style and paddy culture of waterside villages, such as the folk religion, social life, artistic philosophy, regional culture, the landform of waterside villages and the humanity environment. So the folk costume was the significant sign of practical function and also the significative sign of folk traditional culture, both of which composed the costume cultural symbol system of waterside villages of Southern Yangtze called ＂ integration of aesthetic and practical function＂.展开更多

To achieve this objective, we focused on the Peruvian Andes, specifically on Coporaque, an Indigenous village founded in the 16th centuryduring colonial times. In this locality, qualitative research was carried out using the phenomenological approach, prioritizing the lived experience of the native inhabitants in their daily“life world” through in-depth interviews and direct observations. Our results broaden understanding of the Andean vernacular dwelling, making visible the ways in which the “Wasi” becomes a stage for the symbolic occurrence of domesticity. The results reveal several significantnarratives on domesticity that support and give coherence to the life of these Indigenous communities, coinciding with the symbolic value that other cultures have attributed to dwellings.The study was able to conclude on the Indigenous house’s function in sustaining regional identities and how its physical structure is embodied in the inhabitants until it becomes one of thelast bastions of resistance against the homogenizing pressure that the globalized world tries toexert on native peoples.展开更多

文摘Multiple-input multiple-output(MIMO)technology has been promoted to achieve high-speed data transmission.Compared to the orthogonal frequency division multiplexing(OFDM)based MIMO systems,the single-carrier scheme(SC)has attracted lots of attention due to its low peak-to-average ratio(PAPR)feature and is quite suitable for longdistance transmission.However,one of the significant challenges of SC-MIMO systems is the vast complexity of channel equalization and signal detection,especially for the inter-symbol interference(ISI)caused by the multipath channel.The single carrier frequency domain equalization-based minimum mean square error(SCFDE-MMSE)algorithm is proved to achieve satisfying performance.However,it involves large numbers of DFTs and large-scale matrix inversions,which is unacceptable for practical systems.In this paper,a low-complexity SCFDE-MMSE(LCSCFDE-MMSE)algorithm is proposed.Firstly,the characteristics of cyclic matrix and DFT cyclic shift are combined to reduce the number of DFTs.Secondly,SCFDE is transformed into a symbol-wise manner to avoid large-scale matrix inversions.Finally,a frequency-domain interpolation method is proposed to reduce the number of small-scale matrix inversions further.According to the evaluation results,the proposed LC-SCFDE-MMSE reduces the complexity of the traditional SCFDE-MMSE algorithm by more than one order of magnitude with less than 0.1 dB performance loss.

文摘Botticelli’s The Birth of Venus continues to serve as an iconographic enigma and remains an enduring subject of scholarly analysis concerning the significance of mythological art and its symbolism during the Italian Renaissance.Therefore,it is particularly noteworthy to examine further the symbolic elements embedded within the imagery.This essay focuses on a specific component in the landscape of The Birth of Venus-the marsh plant on the riverbank,commonly known as cattail in English,tifa or stiancia in Italian,and Typha latifolia in Latin.Botticelli’s The Birth of Venus,executed between 1485 and 1490,is a tempera on canvas with gesso and gold applications.It was commissioned with specific aesthetic,cultural,and intellectual objectives and was intended to be displayed in a private chamber for personal viewing by members of the Medici family.Situated initially within the Medicean Villa at Castello,it has been exhibited at the Galleria degli Uffizi in Florence since 1815.This mythological painting exemplifies the Italian Renaissance principles of both physical and metaphysical humanism,visualized in a fusion of pagan and Christian iconography and iconology,incorporating symbolism that engages with antiquity and classical mythology.It also incorporates Italian Renaissance Neoplatonic philosophy,reflects Renaissance love poetry,demonstrates inventive patronage,and embodies spirituality directed towards a higher purpose.

文摘William Faulkner’s Southern Gothic style features fragmented narratives and rich symbolism that explore characters’psychological complexity and the decay of Southern society.In his seminal work exploring Emily Grierson’s tragic life,Faulkner employs a rich symbolic system that transcends mere literary decoration,instead functioning as a complex interpretative lens through which the disintegration of traditional Southern social structures can be understood.This paper argues that the symbolic framework in the narrative not only shapes Emily’s personal tragedy but also serves as a profound metaphorical representation of the collapse of the old Southern civilization-a system marked by rigid social hierarchies,racial tensions,and the slow erosion of aristocratic ideals in the face of inevitable social transformation.By dissecting the intricate symbolic elements-from the decaying mansion to the gothic imagery of death and preservation-this analysis reveals how Faulkner’s symbolic methodology becomes a nuanced historical and psychological commentary on the South’s traumatic transition from an antebellum past to a modernizing present.
