Cities want to attract young families as residents instead of losing them to the suburbs. This asks for profound and specific understanding of the housing-related needs and expectations of those families desiring urban living. The article presents and discusses these needs and expectations, focussing on social and environmental issues, as seen by different market actors with regard to a major urban transition area in Basel, Switzerland, a typical middle-sized western European city. We used the exploration parcours technique, which allows for what is called “information acceleration” including an in-depth encounter with different scenarios of urban design before responding to a questionnaire on urban family living (N?=?80). The results indicate that housing suppliers underestimate young families' demand for participation, for the recognition of children's needs, and, to a large extent, for high environmental standards.  相似文献

Using the Instant for the Projects of Science . Focusing on Bachelard's books L'Intuition de l'instant (1932) and La dialectique de la durée (1936), the paper deals with Bachelard's discontinuous and serial concept of time that is formulated against Henri Bergson's concept of duration. With a view to the philosophical concept of monadology, to the theory of relativity, and to the contemporary psychological and neurological research, the paper points to the significance of the instant for Bachelard's concept of temporality, for his desubjectified concept of the individual as well as his discontinuous concept of matter. Moreoever, the paper explores the discontinuous conception of temporality in Bachelard's epistemological writings. The paper argues that Bachelard's discontinuous concept of the specific temporality of science is based on a fundamental discontinuity of reality of both physical as well as psychological processes.  相似文献

In 2008, the archaeological museum in Piła carried out excavations in the site No. 5 in Ujście upon the river Noteć (Poland), at the Rybacka Street and in the Old Market Square. In 12 archaeological excavations and 4 surveys abundant wooden structures were discovered, from which about 800 samples were taken, mainly of pine (Pinus sylvestris L.) and oakwood (Quercus sp.). The studies were aimed at absolute dating of wood with the dendrochronological method, the wiggle matching fitting curves method, as well as anatomical determination of wood. Absolute dating of the oakwood from the Rybacka Street allowed to distinguish the oldest fortifications of the stronghold from the ninth century, and also intensive introduction of wood in the years 980–1080 AD, whereas analysis of wood from the Old Market (survey IV) allowed to distinguish eight structural levels, from the 1530s until the 970s. On the basis of the pine wood 227-year-long local chronology 2U_02A was produced, dated with the wiggle-matching method for the period 860–1080 (±10) cal. AD. Most of the pine samples proved to represent wood introduced in the 990s and 1040s (±10) cal. AD, and also some repairs in the years 1000–1030 and 1050–1070 (±10) cal. AD.  相似文献

The ‘Castle Hill’ represents the core territory of Vilnius, around which gravitated urban development, eventually culminating in the foundation of the capital of Lithuania. However, we know very little about the earliest occupation on Castle Hill - how it developed over time, and what the activities were of the people that inhabited the site. While the study of plant remains can provide a crucial insight into human staple foods, agricultural activities and the palaeoenvironment, previous attempts of archaeobotanical investigations of such an important cultural heritage site was cut short due to the outbreak of World War II. Here is presented the first archaeobotanical analyses from the territory of Castle Hill together with new radiocarbon dates stretching from the 8th century BC until the 14th century AD. The primary archaeobotanical analyses in combination with published datasets from adjacent regions around Castle Hill show that the diversification of crops and the introduction of various crop rotation practises during the 8-13th centuries AD. Here, for the first time, attention is drawn to the agricultural strategies in medieval Vilnius that likely played a pivotal role in the formation and development of the city.  相似文献

ABSTRACT

The integrated results of micromorphology, plant macrofossil, pollen, phytolith, and non-pollen palynomorph analyses represent an important study of two thirteenth-century Teutonic Order castles at Karksi (Livonia), and Elbl?g (Prussia). The research examines deposits that formed during the period of active crusading. At Karksi, the investigation of a midden and of the organic-rich sediment beneath allows the diachronic use of this area to be understood. Freshwater aquatic indicators are consistent with the occurrence of shallow stagnant water, as also suggested by a waterlaid pond sediment identified in thin-section. Coprophilous spore taxa suggest the use of the pond as a watering hole. Plant macrofossils from the midden represent a range of habitats, mostly from wet/damp areas, as well as pastures and meadows, and also woodlands. Fragments of millet are embedded within herbivore dung in thin-section showing the use of this grain as fodder. At Elbl?g, parasite ova may derive from animal feces as they also occur in the dung observed in thin-section, and a range of coprophilous fungal spore taxa were extracted. The results reveal information about the range of livestock that the Teutonic Knights kept, whereabouts within the castles the animals were stabled, and what fodder was used.  相似文献
