Through much of the 1980s, discussions of transformations within work and employment debated the emergence of a new, more 'flexible' era - or, at a different level of analysis, the growth of more 'flexible' working practices. Recent accounts of contemporary socio-economic change have been framed within new sets of theoretical contexts, such as Ulrich Beck's notion of 'social risk'. The central aim of this paper is to evaluate the utility of such an approach, drawing upon empirical work which has investigated changes to terms and conditions of manual employment in British local authorities as a result of the introduction of compulsory competitive tendering.  相似文献

Research within the last 3 to 5 years is summarized for the southern part of the southwestern United States and adjacent northwest Mexico. In an effort to identify important new sources of information, the literature of contract archaeology is cited, along with more widely available journal and book publications. Topics considered include Late Archaic farmers, early ceramic villages, subsistence and agricultural technology, settlement stability and residential mobility, community organization, and developments of the late prehistoric period sociopolitical complexity.  相似文献

The Florentine Francesco Berlinghieri (1440–1501) published his Geographia, a version of Ptolemy's Cosmographia in Italian terza rima, comprising 123 folios of text and 31 engraved maps, in 1482. As early as 1938 Arthur M. Hind, Keeper of Prints and Drawings at the British Museum, hinted that the engravings might have been made by Francesco Rosselli (1448–before 1527), the principal engraver in Florence in the 1480s and 1490s. Subsequently, this possibility was rejected by Roberto Almagià, R. A. Skelton and Tony Campbell. In the author's view, however, both stylistic and circumstantial evidence argues that Francesco was indeed the engraver, and that this first major commission launched the career that eventually made him known to his contemporaries as ‘Franciscus rosellus florentinus Cosmographus’.

Le Florentin Francesco Berlinghieri (1440–1501) publia en 1482 sa Geographia, une version de la Cosmographia de Ptolémée en terza rima italienne, comprenant 123 feuillets de texte et 31 cartes gravées. Dès 1938, Arthur M. Hind, conservateur des estampes et dessins au British Museum, suggéra que les gravures pouvaient être l'?uvre de Francesco Rosselli (1448–avant 1527), le principal graveur florentin dans les années 1480 et 1490. Ultérieurement, cette éventualité fut rejetée par Roberto Almagià, R. A. Skelton, et Tony Campbell. De l'avis de l'auteur, cependant, des preuves stylistiques et circonstancielles démontrent clairement que Francesco Rosselli était en effet le graveur, et que cette première commande importante lança la carrière qui allait finalement le faire connaître par ses contemporains comme ‘Franciscus rosellus florentinus Cosmographus’.

1482 veröffentlichte der Florentiner Francesco Berlinghieri (1440–1501) seine Geographia, eine Version der Cosmographia des Ptolemäus, in italienischen terza rima. Sie umfasst 123 Folioseiten Text und 31 gestochene Karten. Schon 1938 deutete Arthur M. Hind, Direktor der Grafikabteilung am British Museum, an, dass der Stich von Francesco Rosselli (1448–vor 1527) besorgt worden sein könnte. Während den Jahren 1480s und 1490s, war Rosselli der hauptsächliche Florentinische Stecher. Diese Möglichkeit wurde in weiterer Folge jedoch von Roberto Almagià, R. A. Skelton und Tony Campbell verworfen. Nach der Meinung der Autorin sprechen aber sowohl der stilistische Befund als auch die näheren Entstehungszusammenhänge sehr für Francesco Rosselli als Stecher und auch dafür, dass dieser erste größere Auftrag ihm eine Karriere eröffnete, die ihn letztendlich bei seinen Zeitgenossen als ‘Franciscus rosellus florentinus Cosmographus’ bekannt machte.

Active travel is associated with improved health and development outcomes in children. Accurate detection of children's travel behaviors and routes, however, is problematic. Travel diaries are often used to collect information on children's travel behaviors, yet no evidence for the accuracy of this methodology exists. This study investigated the validity of children's self-reported trips (origin, destination) compared with an objective criterion (global positioning systems units; GPS). Children (n = 10, 9–11 y) wore the GPS units for seven consecutive days between March and June 2011 and completed travel diaries daily with researcher assistance. Affinity group interviews were conducted in December 2011 with 30 children from two schools to garner perspectives on trip definition, neighborhood perceptions, and to illuminate GPS and travel diary findings. GPS journeys were manually compared with travel diary journeys for destination sequencing, start times, and travel mode. Accuracy in trip sequencing was compared by day type, and journey type using percentage differences and the chi-square (χ2) statistic. Of the 380 trips captured, 54.5% of journey sequences were fully or partially matched, 22.4% were GPS only trips and 23.2% travel diary only. Greater accuracy (full/partial match) was observed for weekdays than for weekend days and for the journey to or from school than for other journeys. Travel mode agreement existed for 99% of matched trips. Although children's travel diaries may confer contextual journey information, they may not provide completely accurate information on journey sequencing. Thematic analysis of affinity group data revealed that reasons for this are multifaceted, including differing concepts of what constitutes a ‘trip’. A combined approach of GPS and travel diary is recommended to gather a comprehensive understanding of children's journey characteristics.  相似文献

This journal issue developed out of a desire to increase the use of feminist theory in archaeology, leading me to ask Laurajane Smith of York University to co-organize a symposium on the topic for the World Archaeological Congress in Dublin in July 2008. The impacts of major feminist theories on constructions of the past and archaeological thinking are discussed, emphasizing how they implicitly or explicitly influenced other articles in this journal issue.  相似文献

In a 1993 paper, Noble and Crerar suggested, based on the age and sex distribution of white-tailed deer (Odocoileus virginianus) longbones from four Attawandaron Iroquoian sites around the western end of Lake Ontario, that the contact-period Attawandaron were managing local deer populations, in response to the aboriginal trade in hides. Having observed similar patterns of differential preservation of elements and epiphyseal fusion at nearby Iroquoian sites that are not ascribed to the Attawandaron, and which pre-date the hypothesised trading period, we argue that these patterns may instead relate to bone density and/or vulnerability to taphonomic effects of late-fusing epiphyses. We further support our argument through age profiles based on dental eruption and wear.  相似文献
