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

ABSTRACT Growing scientific literature evaluates the impact of traffic-calming devices in terms of mobility behavior and safety, but little is known about their perceived impact from the point of view of children. Our study asks children about their perceptions of different traffic-calming measures around their schools. It draws on data gathered through eight focus groups, followed by walking tours with Grade 6 children (11–12 years old) (n?=?65, 27 boys, 38 girls) from elementary schools in different urban contexts in Quebec, Canada. Qualitative analysis of the discussions shows that (a) vehicle speed is the main perceived threat for participant children; (b) children are confident about the effectiveness of self-enforcing traffic-calming devices that reshape the street geometry; and (c) they are skeptical about the effectiveness of ‘informative’ measures such as signs and lines (marked pavement). Our findings inform public policy for a more effective promotion of walking and cycling among children. 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 A measure of health based on exact sciences is not considered by social sciences to evaluate human development. We propose the H measure of information of Shannon ([1948]. “A Mathematical Theory of Communication.” The Bell Systems Technical Journal 27 (3): 379–423, 623–656), renamed as H cto , as a general indicator of human health which can be subsequently aggregated at any statistical level. Several advantages of H cto are explained: (i) connections with thermodynamics and information theory; (ii) combination of physical and statistical elements; (iii) measurements of entropy and/or information depending on the reference point, and (iv) a collection of examples based on the scientific literature that supports the application of H cto . Simplified graphical models of the ontogeny of health condition are also shown. The empirical feasibility of using H cto is also analysed, by concluding that it could be a tangible reality in the near future. 相似文献

In spite of the interest generated by Phoenician‐Punic Archaeology, this area of study has always been underestimated by comparison with Classical Archaeology. One of the main reasons for this is the persistence of a colonial representation of the ancient Mediterranean which assumes Greek culture to be the supreme expression of civilization. Other groups may imitate it through an acculturation process: Hellenization. As we shall see, this representation pervades even the Phoenician‐Punic history and archaeology university textbooks. Starting with the various reasons leading to this situation, I aim to focus on the interpretation given to the ancient excavations at Carthage and, specifically, to its architectural and urban record, since this was the area of study where the prejudices about the Phoenician‐Punic culture found an (albeit misunderstood) archaeological proof. I shall argue that the misinterpretation of these excavations is the key to understanding later developments and the general underestimation of Phoenician‐Punic Archaeology. 相似文献

In January 2016, the first publicized decision made by the president of the newly installed Venezuelan parliament, Henry Ramos Allup, was the removal of pictures from the legislative premises. In what transpired as a calculated performance, this member of the old political guard was captured on video dismissively instructing removal workers to send pictures of Chávez away to Sabaneta (Chávez's birthplace), or into the rubbish bin. He also commanded the removal of recent representations of Simón Bolívar, disqualifying them as ‘an invention of that mister [Chávez], a crazy thing’. This episode signalled the intensification of an ongoing struggle over political symbols in Venezuela. This article discusses the background and implications of such a struggle, focusing in particular on the figure of Chávez as the epitome of a contested national symbol. The fate of Chávez's corpse, currently located in a mausoleum, is at stake, but also the configuration of the institutionally sanctioned symbolic order with which political actors aim to condition political manoeuvring in years to come. 相似文献

ABSTRACT Pastoralism and camelid management have been essential to all aspects of pre-Hispanic Andean societies. Here, we present zooarchaeological and isotopic data on domestic camelid remains from Huaca Cao Viejo (El Brujo archaeological complex) on the northern coast of Peru, and dated to the Lambayeque/Sicán period—to characterise their biological age, diet, life history, possible geographic origin and ritual use. Domestic camelids, representing a wide range of biological ages and a high rate of polydactyly, were found as burial offerings in direct association with human funerary bundles (fardos). Direct AMS dates indicated that camelids were buried over a short period of time (AD 1022–1176) confirming the Lambayeque presence in the Chicama Valley during the first half of the Late Intermediate Period. Stable isotopic analyses were carried out on both bone collagen and hair keratin, including incremental analysis. A considerable variability in δ13C values at both the intra-individual and the intra-group level and a large contribution of C4 resources to diet are shown. This clearly supports local management and camelids originating from various herds. Zooarchaeological and isotopic evidences suggest diversity in herding practices and suggest the importance of the herds in fulfilling the transportation demands for trade in goods. 相似文献

ABSTRACTThe 2010 Maule Chile earthquake (Mw 8.8) caused extensive structural damage to the built heritage. In particular, the poor seismic performance of a set of unreinforced masonry (URM) churches highlighted the need to implement protective and safety strategies in order to preserve these buildings which exhibit unique constructive and typological features, as a result of a combination of Chilean and European construction cultures.The peculiarity of this heritage and the high seismic hazard of Chilean territory have motivated the present study which aims to apply systematic procedures to assess the seismic vulnerability of these buildings. This article is of archival nature and presents a complete database generated from the geometrical, constructive, and structural characteristics of a representative stock of 106 churches located in central Chile, with the goal of proposing fragility curves to be used in seismic risk assessment. Considering variables related with geometrical, architectonic, and stylistic features, as well as damage levels for the 2010 Maule earthquake, this church sample is classified into three homogenous groups: colonial, neo-classic, and neo-gothic. Moreover, a preliminary qualitative assessment of the seismic capacity of these structures is provided using a survey and analysis of geometric indices for each of the three selected groups. 相似文献
