In this article, I focus on the construction and restoration of houses in the Catalan Pyrenees, on their materiality, and specifically on the relationship between architectural and heritage processes that shapes them. I provide an analysis of how architectural forms, norms and regulations, as well as building aesthetics and materials, were transformed in the past decades following a parallel process of changes in the region. The aim is to explore the relationship between the built environment and the cultural and economic shift of the area in recent times. Drawing on extensive ethnographic research conducted in a valley of the Catalan Pyrenees, I show how the material culture, architecture and built environment evolved in close relationship to the spread of heritage discourses leading to a mutually constituting association that helped shape the elements of the new social realities. 相似文献

The nature of British rule in Palestine, as it settled down after the approval of the Mandate in 1922, had its critics among the Zionist ranks. Using original sources, this paper examines the attitudes of the leadership of the Revisionist Union (RU) towards the British from the first quarter of the 1920s till the mid-1930s. Unlike the later paramilitary organizations, the Revisionist founders, convinced, in their own words, of the common interests shared with the British Empire, had no intention of terminating the British presence, but sought to transform it in order to serve Zionism’s objectives. While official Zionism preferred backstage diplomacy, the RU pursued a different strategy – appealing directly to the masses and making its cause as public and vocal as possible. Eventually, the RU’s strategy combined the principle of pro-British orientation with merciless criticism of Palestine policies on the ground. As far as the British were concerned, the Colonial Office was at best willing to tolerate a set of proposals they saw as unrealistic. Once these started to actively erode the integrity of British policy in the region, unsolicited “enthusiasm” was reclassified as dangerous “extremism.” 相似文献

ABSTRACT In the late seventeenth century, when Spain gradually emerged from the general crisis that had afflicted the country, several members of the cultural elite became acquainted with the new sophisticated theories and methods of modern science. This newly acquired knowledge inspired these novatores (innovators) to examine Spain’s history and historiography. They intended in the first place to integrate and align Spain with European culture at large, since the religious and ideological obstacles of the past were supposedly no longer in force. Their second purpose was to establish a scientifically based historical discourse focused on the genuine achievements of Spain over the centuries and its contribution to European civilization. They were thus willing to confront the long-standing distortions arising from propaganda, either from the outside—such as the “black legend” forged by the enemies of Spain—or from inside—such as the “fake glories” forged by earlier historians. Diverse circumstances, however, limited their enlightened endeavour, and whoever was eager to resume it in the eighteenth century came up against the restrictions imposed on modern culture by Enlightened despotism. 相似文献

Particle-induced X-ray emission (PIXE), X-ray diffraction (XRD), electron microprobe analysis (EDS) and scanning electron microscopy (SEM) analytical techniques were used to characterize surface paints in pre- and post-fired Aguada Portezuelo decorated pottery. Surface paintings in black, white, red, brown, burgundy and ochre were analysed. Major, minor and trace elements were detected by PIXE, whereas XRD and SEM-EDS gave information on the main mineral phases and the characteristic morphology for each analysed pigment. The results obtained indicate that the main colour groups can be easily discriminated by PIXE, and they are characterized by only one pigment for each colour: hematite (red) and manganese mineral oxides (black), respectively, whereas white pigments are characterized by calcite, ghelenite and gypsum. 相似文献

This paper compares the quantification of different raw materials in a chipped stone assemblage by weight and by number at the site of Brno-Štýřice III in Moravia, Czech Republic. The use of the same reduction technology for all raw materials means that the Brno-Štýřice III assemblage is a good case study. The result demonstrates that semi-local raw material tends to dominate numerically, but in terms of weight, there is a significant change in the predominant raw material. The paper contextualizes the results in relation to other assemblages and discusses the possible reasons for this phenomenon. 相似文献

The study analysed pre-Hispanic gold objects found within a surprising archaeological finding of a structure that likely served as a funeral pyre in Medellín, Colombia. 14C analyses of the site's organic materials dated the structure to the fifth century ce . The metal objects were subjected to X-ray diffraction (XRD), energy-dispersive X-ray fluorescence (EDXRF), scanning electron microscopy-energy dispersive X-ray (SEM-EDX), density measurement by the Archimedes method, and metallographic analysis. The measurements by EDXRF and SEM-EDX showed that the pieces were composed mostly gold and silver. The XRD results indicated that the microstructure of the objects corresponded to a single phase of gold and silver. The images obtained by the metallographic microscope showed equiaxial grains with some twins, a structure consistent with annealed metals. The different colours observed correspond to different grain orientations. Pre-Hispanic objects from a second archaeological site in the municipality of Amalfi (Department of Antioquia) were also analysed for comparative purposes. The results showed that the gold objects were not subjected to any alloying process, but were instead manipulated in their original form (native gold). The shape of the objects and their microstructural results suggested that the pieces were manufactured by casting, mechanical deformation and then annealing. 相似文献

In north-western Patagonia, obsidian was used during the entire Holocene, and its importance increased with time. Recent fieldwork discovered a new obsidian source located in the Río Grande, which was called ‘Coche Quemado' (CQ). The results indicate that the CQ source has a different geochemical signal than all other sources in the region. Its use is spatially restricted to piedmont and, to a lesser extent, the plains. Chronologically, CQ was exploited in the middle and late Holocene, and its use accounts for a range of spatial distribution between 150 and 200 km. 相似文献

AbstractDespite the growing number of pregnant women engaging in outdoor adventure activities, very few studies have explored pregnancy or the specific needs and challenges of pregnant women in tourism research. To fill this gap in the literature, we examine the participation of pregnant women in adventure tourism through the theoretical lens of liminality. Conceptualising pregnancy as a liminal stage in which women are ‘suspended’ between two statuses, opens diverse possibilities to delve into women’s experiences of embodiment, bodily image and control. In this sense, pregnancy is understood as an ‘internal change’, which adds specific challenges to women’s practice of adventure tourism, including bodily changes and different perceptions of risk-taking. Similarly, the context of adventure tourism provides an ideal space to reflect on liminal transitions and the ‘outside changes’ that pregnant women go through in the predominantly masculinised spaces that characterise this tourism segment. Semi-structured interviews were conducted with 35 Mexican women who actively pursue adventure tourism and who had engaged in these activities during at least one pregnancy. The analysis indicates the importance of norms and social expectations experienced by pregnant women when doing adventure tourism. The concept of the ‘rhizomatic body’ proved to be a valuable tool when looking at the social taboos, prohibitions and rules that apply to pregnant women in specific sociocultural contexts (in this case, Mexico). By reframing and reconceptualising pregnant women and their practice of adventure activities, the social construction of pregnancy is elucidated. Finally, the study contributes to the understanding of alternative models and experiences of being a woman in gendered spaces, while shedding light on relevant behavioural patterns among pregnant tourists and the sociocultural impacts of these patterns. 相似文献

ABSTRACTMorphometric analysis offers an alternative or augmentation to traditional archaeobotanical methods to address differences within and between plant species and their remains, refining and enhancing taxonomic resolution. Morphometrics, the measurement of size and shape, and the multivariate statistical analysis of generated quantitative variables, have long played a major role in biological research, including plant taxonomy and systematics, although its application in archaeobotany is relatively recent. Over the last few decades, there has been an increasing interest in the use of morphometrics for analysing a varied range of archaeological plant materials (mainly seeds, pollen, phytoliths, and starch grains). In particular, morphometrics have contributed to the study of the domestication and spread of many cereals world-wide, as well as that of other taxa including legumes, underground storage organs (USO), and fruits (such as olives, grapes, and dates). This paper reviews current methodologies, recent applications, and advances in the use of morphometrics in archaeobotanical research, discusses its role in exploring major research questions, and suggests possible future directions for its use. 相似文献

ABSTRACT The preservation of the architectural heritage is characterized by the intervention of different technicians, who may disagree on decision-making criteria. In recent years, the H-BIM methodology has emerged to manage these buildings, although the multidisciplinary technical personnel make the decision-taking something of a challenge. In this regard, artificial intelligence may be an opportunity to establish automatic responses, thus optimizing the process. This article proposes a methodology to implement models of classification using the J48 algorithm in a H-BIM model. The case study was focused on a tiles panel from a building which belongs to the Real Alcazar of Seville. First, a model of classification was developed to estimate the degree of intervention with an adequate degree of adjustment. Then, the model was implemented in the H-BIM software by programming using GDL. This methodology automates the decision-making and reduces times of assessments, visualizing and managing the information in the H-BIM model. 相似文献
