In this article we argue that the ‘just city’ is one that enables individuals to exercise their citizenship, including making choices to participate (or not) in communal existence. However, inequities in resource distribution encountered by lone mothers on income assistance threaten not only individual sustenance and survival, but also the foundational fabric of our society. The implication that an active citizen is one who exercises their rights and responsibilities in a balanced way is problematic, and has the potential to add blame to poverty, justifying exclusion rather than inclusion. Using qualitative data from a longitudinal study of lone mothers in extreme poverty in Vancouver, British Columbia we illustrate how macro-processes within cities (i.e., delivery of affordable housing, food security, childcare, transportation) impinge upon the micro-processes of these women's lives (i.e., impacts on health, economic security, social mobility). Focusing on citizenship as a set of constrained choices challenges the policies and practices of social planning to consider how the scope of citizenship can be expanded by shaping key urban opportunities. Grounding the vision of a just city in the potential for personal agency suggests that policymakers and planners have a key role in shaping citizenship for the most marginalized and oppressed through a combination of providing supports and enabling opportunities in the urban environment.  相似文献

The mapping abilities of four-year-old children in York, England, Durban, South Africa, Tehran, Iran, Mexico City, Mexico and Evanston, Illinois, USA were investigated, using a methodology involving air-photo identification and simulated navigation on an air photo. The results show that essential mapping abilities (perspective and scale transformations) are well developed by the age of four in these cultures, and provide some evidence in support of the hypothesis that mapping abilities emerge without training in very young children of all cultures.  相似文献

During the Middle Ages, gender-neutral representations of humility as a quality linked to spiritual love and voluntary service competed with representations according to gendered patterns, such as those related to the naked and dressed body in terms of its biological and social functions and its appearance. Moving from Dante's examples of humility in Purgatory, Canto X, this article focuses on representations of humility in textual and pictorial sources authored by women and men between the thirteenth and early fourteenth centuries in Italy. By showing the complexity of these representations, this article revisits and reconsiders one-sided historiographical narratives according to which humility in the Middle Ages was intrinsically, persistently and negatively related to feminine suppression and servility.  相似文献

This paper presents a multipronged scientific study of mortars and plasters of the so-called Ginnasio in the Hellenistic–Roman city of Solunto (Sicily, Italy). A selection of 16 well-contextualized samples was collected to represent different functions and building phases of this private house. The results show that a variety of locally available raw materials was used as aggregates and to produce binders. The diversity of raw materials’ sources and production techniques identified in this study reveals the advanced technological knowledge of the builders of Solunto, indicating a complex relationship between the settlement's cityscape and its surrounding landscape.  相似文献

Daily growth increments in fish otoliths have been demonstrated for the first time on Quaternary sagittae from a late palaeolithic site in Egypt and they have allowed us to establish the season of fishing. Transverse sections of tilapia sagittae studied under light-microscope demonstrate that recrystallization during diagenesis renders the majority of the margins unreadable. The well-preserved otoliths, however, all have widely spaced outer growth lines, indicating that the fish died during a period of fast growth which coincides with the flood season. Moreover, counting the daily increments showed that late palaeolithic man captured the animals on the floodplain of the Nile after the maximum of the flood, when residual pools were present.  相似文献

Studies of criminal deterrence usually show an effect of certainty of punishment but often fail to find an effect of the severity. This is a serious threat to the theoretical underpinnings of deterrence theory. Through both a survey of 39 analyses in 33 published studies and our own reanalysis of an often-used data set, we show the problem rests not with the theory but with the analysis of the theory. Finding no severity effect can be traced to "unbundling the theoretical package" when moving from the theory to the statistical models used to represent the theory.  相似文献

Knowledge of the embalming methods used in Renaissance Italy comes not only from the literary texts of physicians and surgeons of that period, but also from artificial mummies which have been found. In 1999 two mummified bodies, dated back to the end of 15th and beginning of the 16th century, were recovered in a crypt of the hospital chapel of Santa Maria della Scala in Siena (central Italy). The individuals were identified as Salimbene Capacci (1433–1497), Rector of the hospital, and his wife, Margherita Sozzini (?-1511). The mummies were submitted to autopsy and paleopathological examination, which included Computed Tomography. Palaeobotanical and palynological analyses were performed on the vegetable materials and plants used to fill the body cavities. This study was carried out with a multidisciplinary perspective, that allowed us to reconstruct the embalming techniques and substances used for mummification. The results are compared with the evidences provided by other mummies and embalming handbooks of that time.  相似文献

ABSTRACT

Earthquakes cause severe damage to masonry structures due to inertial forces acting in the normal direction to the plane of the walls. The out-of-plane behavior of masonry walls is complex and depends on several parameters, such as material and geometric properties of walls, connections between structural elements, the characteristics of the input motions, among others. Different analytical methods and advanced numerical modeling are usually used for evaluating the out-of-plane behavior of masonry structures. Furthermore, different types of structural analysis can be adopted for this complex behavior, such as limit analysis, pushover, or nonlinear dynamic analysis.

Aiming to evaluate the capabilities of different approaches to similar problems, blind predictions were made using different approaches. For this purpose, two idealized structures were tested on a shaking table and several experts on masonry structures were invited to present blind predictions on the response of the structures, aiming at evaluating the available tools for the out-of-plane assessment of masonry structures. This article presents the results of the blind test predictions and the comparison with the experimental results, namely in terms of formed collapsed mechanisms and control outputs (PGA or maximum displacements), taking into account the selected tools to perform the analysis.  相似文献
