Outdoor lighting design as a tool for tourist development: the case of Valladolid

Practices of outdoor illumination have dramatically changed in the last decades as functional lighting has progressively given way to a more qualitative vision of light. Its traditional role for security purposes has been progressively matched by the use of illumination for city beautification. This is now a major consideration for new lighting strategies. As a result, a growing number of European cities explicitly include the development of nocturnal tourism among the objectives of their lighting policies. However, little attention has been paid by academic research to this growing trend. Focusing on the internationally renowned lighting project ‘Ruta de los Rios de Luz’, this research paper explores the use of lighting design for tourism purposes. Through interviews with individuals who played an important role in the project, the discussion below scrutinizes the lighting design decisions and the economic, environmental and political objectives that inspire the growing utilization of spectacular forms of illumination for tourism purposes.     

A Bayesian approach to rapid seismic vulnerability assessment at urban scale

The seismic vulnerability of city centers is commonly assessed by extending the study methods applied to single buildings to urban aggregations. This approach is not always applicable at territorial scale, as it is uneconomical in terms of time and costs. An innovative method provides reasonable large-scale a priori estimation of parameters not directly evaluable from the exterior of buildings by elaborating values which can be measured from the outside. Those parameters are treated as continuous variables, by assigning them a suitable probability density function. The Bayesian approach is adopted, which allows the update of initial hypotheses by using new data gathered during on-site surveys. In this regard, a rapid survey form for the on-site data collection is proposed. An example of its application to a façade of a building structural unit in Santo Stefano di Sessanio in L’Aquila province (Italy) is proposed, showing promising preliminary results for buildings belonging to Italian historical centers.     

The Influence of Dowel-Bearing Strength in Designing Timber Pegged Timber Joints

ABSTRACT

The employment of timber pegs in timber structure joints is a widespread technology in the field of timber frame building in the United States, where the Timber Frame Engineering Council has published a special Standard to supplement the National Design Specification for Wood Construction. The authors have been studying the possibility of supplementing the Eurocode 5 design formulas, thought for timber joints with metal connectors, with specifications needed for a reliable design when employing timber pegs. The field of application envisaged is that of restoring timber structures and results obtained until now are quite encouraging. In this step of the research, more attention has been paid to deformation process: fir and chestnut samples have been tested to determine their dowel-bearing behavior with steel and ash timber peg while double-shear plane joints made of the same wood species, and fastened with steel as well as timber pegs, have been analyzed.     

Identification Technique for Soil-Structure Analysis of the Ghirlandina Tower

Historical towers, in particular medieval towers, are an important part of cultural heritage, and their preservation mandates monitoring and detailed analyses of vulnerability under seismic actions as well as of their long-term performance. Certain aspects of structural nature are linked to the masonry behavior as a unilateral material, and other are aspects related to the interaction with soft soil conditions. This study aims to contribute to the aspects of preservation by exploring the role of the soil-structure interaction in predicting the behavior of the structures, with specific reference to the well-documented case history of the medieval Ghirlandina Tower (Modena, Italy). A significant contribution comes from an experimental identification analysis, performed in the presence of ambient vibration. A novel finding is that the soil structure interaction cannot be neglected, in contrast to most published identification analyses that usually assume the structure to have rigid constraint at base.     

Knowledge Production,Urban Locations and the Importance of Local Networks

This paper analyses the relationship between knowledge production and urban locations in industrial design, a knowledge-intensive business service (KIBS). KIBS concentrate in urban locations. This is often explained by the co-location of client firms and market access in large cities. Recent research on knowledge production, however, reveals that knowledge productive networks are significant for both the competitiveness and location of KIBS. Thus, to understand the urban location of industrial design, it is important to analyse how knowledge production is organized within the industry. Industrial design is concentrated in urban locations, but most of its clients are located elsewhere. Hence, it seems that industrial design firms concentrate in urban locations mainly because their knowledge networks include specific types of formal and informal local social networks.     

How clothing design and cultural industries refashioned frontier masculinities: a historical geography of Western wear

Gendered subjectivities emerge historically and geographically, not only in situ, within an ‘authentic’ origin period or site, but through later retrospective commodifications and fantastical popular culture depictions. This article traces the masculine identity of the cowboy as commodified and performed through clothing. The cowboy emerged from colonial origins as a model and myth of frontier masculinity: the ‘rugged outdoor type’. But it was then formularized and stylized when subject to popular culture diffusion, and as accompanying clothing design evolved. Through clothing – advertised by metropolitan manufacturers and consumed across America and beyond – an archetypal, sexualized cowboy ‘look’ thus emerged. The author traces a historical geography of cowboy masculinities in clothing design, from early ‘frontier garments for the outdoor man’ to later Western-wear ‘for that long, lean look’. Related constructions of femininity are also considered, after women's Western-wear clothing lines were produced in the 1950s. To illustrate, I draw on archival brochures, catalogs, and advertising materials from the 1920s to 1970s, as well as discuss the material design of the clothes themselves. I focus especially on the Western snap shirt – an apparel item never actually worn on the nineteenth-century colonial frontier, but that became an ‘essential’ element of the cowboy look, and a vehicle for masculine appearance. Western-wear epitomizes how gendered subject positions are visually constituted in relational fashion via bodies, materials, media, and imagined geographies.     

Seismic vulnerability assessment and fragility analysis of stone masonry monastic temples in Sikkim Himalayas

Buddhist monasteries in Sikkim Himalayas constitute important religious and architectural heritage. These random rubble (RR) stone masonry structures located in high seismically active regions of the Himalayas have suffered varied degrees of damages in the past earthquakes. The study presents seismic vulnerability assessment of four archetypal monastic temples using finite element (FE) analyses. Linear and nonlinear analyses of these structures were conducted in Abaqus FE environment. These analyses identified the damage prone areas of the structures and provided load-deformation behavior under lateral loads. Fragility analyses indicate a high probability of collapse for the specified design level earthquake of the region. The study shows that performance of the structure can be enhanced by improving the strength and stiffness of the stone masonry walls.     

‘Always like never before’: learning from the lumitopia of Tivoli Gardens

Drawing on a detailed analysis of the historical and current development of lighting in Copenhagen’s Tivoli Gardens, this article addresses how this site of extraordinarily diverse illumination exemplifies a carefully orchestrated balance between (1) muted and more vivid forms of lighting, (2) curation of historical styles and promotion of contemporary innovations in illumination and (3) artistic luminaires and those more aligned with popular tastes. Through these themes, we argue that the current strategies towards urban lighting that predominantly promote energy conservation, security, commercial imperatives and place-branding may be supplemented by place-specific design strategies that implement multiplicity, connect past and present, and accommodate diverse desires, dreams and realities. These attributes contribute to the ongoing emergence of what we call a ‘lumitopia’, a space in which an intensified attention to illumination is integral to the particularity of a place or landscape. In the case of Tivoli, this offers a lens to manage nocturnal space so that it becomes more aesthetically complex, inclusive and convivial.     

Urban memory and planning: investigating the use of oral history

Investigation of the reciprocal relation between individuals and space within its cultural and historical evolution allow us to conceive the intrinsic qualities and dynamics of any space in its context and to develop new conceptions to explain what kind of a place it is. Oral history provides opportunities to listen to the voice of space as well as a new way to discover its unique and different characteristics that give the users the feeling of belonging and place attachment. In this study, the place of oral history method in historiography, its use in diverse disciplines related to the shaping of urban space, such as urban planning and architecture, and the possible contribution of oral history to planning and designing urban space are discussed. It is revealed that the use of oral history in research and practice can give effect to develop a sense of belonging for all users and to achieve sustainability of urban memory. For this reason, place-based studies and utilization of oral history method within them are of significant importance, for either acquiring the knowledge embedded in memories or understanding the expectations of users or to provide solutions to place-based problems.
