Stories about building history told by wooden elements – case studies from Eastern Austria

The intention of this article is to show the benefit of an interdisciplinary approach within the various disciplines of building research (architectural archeology, art history, archive research, dendrochronology, etc.).

The exact determination of the age of historical timber is undoubtedly the most important contribution of dendrochronology to building research. The significance of dendrochronological dates is discussed in detail—problems of reuse, repair, drying time, and differences between felling and building dates are demonstrated. Several case studies in Eastern Austria showed a difference of two to four years between felling and building.

To answer questions of where the timber came from, dendroprovenancing was introduced to Eastern Austria. First results showed that it will be possible to differentiate the origin of timber between Eastern Austria and regions where rafts started towards Vienna, via the river Danube. The results showed that it is important to combine building archaeology and archival analyses with the dendrochronological results.     

Building survey forms for heterogeneous urban areas in seismically hazardous zones. Application to the historical center of Valparaíso,Chile

ABSTRACT

Building survey is an essential data-collection procedure to feed large-scale seismic vulnerability assessment. The available strategies usually consider survey forms to gather information about the urban buildings. The application of the available survey forms poses important challenges for the case of the heterogeneous urban centers including different structural typologies. This work proposes four specific survey forms for traditional structural typologies constructed with masonry, reinforced concrete, mixed steel-reinforced concrete, and timber. The proposed forms request essential information on the parameters necessary for seismic vulnerability assessment, by evaluating the lateral-load resistant system, regularity, condition of conservation, and existing damages. The survey forms were applied to the study of 111 buildings of the historical center of Valparaíso, Chile. The proposed methodology was complemented with the use of Geographic Information Systems to obtain a complete database with the structural characterization of the most representative typologies for future works of large-scale seismic vulnerability assessment.     

Non-linear relationship between bulk δC and percent maize in carbonized cooking residues and the potential of false-negatives in detecting maize

Bulk δ¹³C values on charred cooking residues adhering to pottery sherd interior surfaces have been used as a source of information on the histories of maize in various locations in the western hemisphere. This approach is based on an assumption of a linear relationship between the percent maize in the resource mix cooked in a pot and δ¹³C. Previous experiments suggest that this relationship is non-linear, and maize may not be identified from bulk δ¹³C values even when it contributed substantially to the resource mix. A second round of experiments, presented here, indicates that the mobilization of carbon from maize and C₃ resources over time is the critical variable in residue formation and the resulting bulk δ¹³C value. This is influenced by the form of maize being cooked.     

新中国农村基层政权初创时期的历史考察

1949～1957年,新中国农村基层政权的建设经历了四个阶段:1949～1950年,在新解放区进行了以废除保甲制为中心的接管建政;1950～1953年,以土地改革为中心进行群众建政; 1953～1954年,以普选为中心进行民主建政;1954～1957年,在农业合作化运动中实现了农村基层政权的调整与发展。经过这几个阶段,新中国的农村基层政权逐步建立起来。其中蕴含的历史启示是:农村基层政权建设的基石是中国农村社会的现代化转型;农村基层政权建设的核心是农村基层民主的发展;农村基层政权建设的关键是加强中国共产党执政能力建设。     

Some Insights on the Aterian in the Libyan Sahara: Chronology, Environment, and Archaeology

The Aterian has a huge geographic extension covering all North Africa, although it was not supposed to exist in the mountain ranges of the central Sahara. Its chronological context is not yet definitively determined and it is still difficult to say whether the Aterian tools are technological, typological, functional, or chronological markers. Recent surveys and excavations at Uan Tabu and Uan Afuda, two rock-shelters located in the central Tadrart Acacus, provide the first chronological, environmental and archaeological indications on this Late Pleistocene human occupation in the area. The lack of organic matter led us to perform OSL and TL analyses on sand. L'Atérien a une énorme extension géographique qui couvre tout le Nord de l'Afrique, tandis qu'on ne pensait pas qu'il existait dans les montagnes du Sahara central. Son contexte culturel n'est pas définitivement déterminé et il est encore difficile de dire si les instruments atériens sont des indicateurs téchnologiques, typologiques, fonctionels ou culturels. Reconnaissances et fouilles récentes à Uan Tabu et Uan Afuda, deux abris situés dans l'Acacous central, fournissent les premières indications sur la chronologie, l'environnement et l'archéologie de l'Atérien dans la région. L'absence de la substance organique, nous a porté à faire des déterminations OSL et TL sur les sables.     

试论大同操场城北魏建筑遗址的性质

2003年发掘的大同操场城北魏一号建筑遗址为一长方形夯土台基,台基东、北、南三面设踏步,其中南面为东西并列的双阶形制。根据遗址在平城中的位置、建筑形制以及出土遗物,再结合考古材料与文献的对比,可以认为遗址位于平城宫殿区,推断为北魏平城的宫殿建筑遗址。

从工业化到全面建设小康社会目标的考察

以毛泽东为代表的中国共产党人,在发展目标上变工业化为四个现代化,开始摆脱苏联片面发展重工业的发展模式的影响;以邓小平为代表的中国共产党人,在决策怎样进行现代化建设时,提出走自己的路,建设有中国特色的社会主义,确立了三步发展的战略目标,使社会主义中国日益兴旺起来;以江泽民为代表的中国共产党人,在各种困难和考验面前,与时俱进,使第二步目标提前实现并开始向第三步目标迈进,使中国特色的社会主义显示出勃勃生机;十六大确立全面建设小康社会的奋斗目标,把邓小平设想的50年发展的第三步目标进一步具体化。
