    Construction of gender through fashion and dressing

    During the last two centuries, the definitions of gender were bounded by increasingly blurred lines, expressing the cultural uncertainty surrounding masculinity and feminity. Besides it is known that gender is a social construction (and not only determined by biological sex). Two basics social - cultural factors that shape the gender are dressing and fashion. A chorography (especially the last two centuries) shows these different constructions of masculinity and femininity. The battle for the use of trousers by women (from Coco Channel and stars of Hollywood Greta Garbo, Marlene Dietrich and Katharine Hepburn play a significant role) confirm the different treatment of male and female. Fashion, which in essence is the fantasy of escape from the typical role of individuals, guiding and shaping the male and female roles, with the major fashion designers to play the key role in shaping it. Dress movements such as Macaroni (1760 - 1780), Baeu, (early 18th century), Dandies (early 19th century) and Mods (20th century) and various teen subcultures show differentiation trends of certain groups. Unisex style has tried to conceal gender differences showing a masquerade of equality for all (with the hippies and Ravers to have the basic role). On the contrary androgynous style seeks to unite the male and the female body, leading to a return to a primordial cosmic unity that will appease the gender confusion and anxiety. But eventually style and androgynous Unisex highlight the differences between the sexes.peer-reviewe

    Comparative Study of SO2 and SO2/SO3 Poisoning and Regeneration of Cu/BEA and Cu/SSZ-13 for NH3 SCR

    Two copper-exchanged zeolites, Cu/SSZ-13 and Cu/BEA, were studied as catalysts for the selective reduction of NOx by NH3 (NH3-SCR). Their activities for standard SCR (NOx = NO) and fast SCR (NOx = 50% NO + 50% NO2) were measured before and after sulfur poisoning at 250\ua0\ub0C. The effect of 30\ua0ppm SO2 and a mixture of 24\ua0ppm SO3 + 6\ua0ppm SO2 was evaluated. The repetition of subsequent activity measurements served as regeneration method in SCR conditions. SO2 deactivated Cu/SSZ-13 whereas Cu/BEA was only moderately affected. SO3 led to stronger deactivation of both catalysts than SO2. However, also for this case, the Cu/BEA was significantly less affected than Cu/SSZ-13, even though Cu/BEA contained larger amount of stored sulfur. One possible reason for this could be the large pores of Cu/BEA, where the sulfur species possibly resulted in less sterical hindrance than in the small pore SSZ-13 structure. NH3 temperature-programmed desorption (NH3-TPD) showed no loss of storage sites upon sulfur treatment and subsequent regeneration. Partial activity recovery was observed after a period in SCR conditions at 400\ua0\ub0C and 500\ua0\ub0C. Temperature at 300\ua0\ub0C was insufficient to regenerate the catalysts. Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) of NO adsorption suggested that SO2 interacts with the ZCuOH sites on Cu/SSZ-13, causing the strong poisoning

    Folklore research and its new challenges : from the ethnography to netografy

    Folklorists use the ethnographic method enriching it with anthropological background information. Ethnography is a method that describes a culture and its “wisdom”. Ethnography is interested in the reasons of change of a specific culture and/or the ways of breaching and restoring the dominant cultural class and to understand the fragile and fluid processes of social control and the rules laid down by the members (of the culture) in order to maintain their cultural characteristics. In recent years the Internet became a cultural environment without boundaries, which confirms the claim of Dundes and Pagter (1992) that the urban folklore allows the coexistence of individuality within the collective identity of each folk group. In online communities multipurpose virtual environments are developed (Economou, 2006) creating virtual locations (places) and developing social interactions and cooperation. In these environments, ethnographic research produces new terms such as netography, cyberethnography, cyber-nations, digital indigenes, digital settlers, digital immigrants, etc. Virtual communities and networks pose particular challenges and opportunities for ethnographic research, as they represent a huge archive of human activity and unprecedented volatility (Jones, 1999, Lindlif and Shatzer, 1998). Virtual, field research studies, with increasing interest, a social world which is characterized both as global and digital, which was previously ignored by conventional ethnography (Hine, 2005). This makes the ethnography of digital life an important aspect of contemporary social research, as we will try to demonstrate with this paper.peer-reviewe

    Folk culture and digital enriched books : the case study of the digital enriched tool “e-anagnosis”

    Get PDF
    This proposal refers to the dissemination and projection of folk culture through the use of digital books (e-books) and more specifically through enriched and immersive e-books. The enriched e-books are developed in parallel to the e-book such as ePUB, PDF and Mobipocket, the digital or electronic book such as HTML, TXT, RTF, DOC, etc and devices used as e-readers such as the e-book reader, the iPAD and other tablets as well as the PC. The enriched e-book is a digital edition of a book which is digitally enriched with a variety of items such as videos, photos, animations, quizzes, maps and special symbology that leads to hyperlinked locations inside and outside of the book such as Wikipedia, youtube, dictionaries and thesauri as well as other sources. The relation of folk culture with digital reading (e-reading) can be used in education and training initially through the creation of learning assets. These learning assets can then evolve to complex learning resources and be re-used as digital material units aiming at education and training. This paper focuses on the presentation of commercial and public efforts to enrich digital books, such as: a) the platform with the enriched digital schoolbooks by the Ministry of Education in Greece (digital school), and b) the Greek application for digital reading and writing of rich digital books with the title “e- Anagnosis” (Marginalia Composer & Paspartu), which can be used in folk culture with a specific example (case study).peer-reviewe
