Modelling Potential Socio-economic Determinants of Building Fires in South East Queensland

This paper investigates the relationships between areas of building fire incidence, levels of socio-economic disadvantage and the underlying socio-economic characteristics in the South East Queensland (SEQ) region, Australia. Disaggregated fire incident data was acquired from the Queensland Fire and Rescue Service (QFRS) and then aggregated to the Statistical Local Area (SLA) level. The Australian Bureau of Statistics (ABS) defined index of socio-economic disadvantage (called ‘SEIFA’) has been used as the basis to identify relationships between socio-economic disadvantage and building fires. A regression model was then developed to predict the incidence of building fires using a range of socio-economic variables. Five significant predictors were identified that include: i) percentage of unemployed, ii) proportion of Indigenous population, iii) families living in separate dwellings, iv) one parent, and v) parent families with children less than fifteen years of age. Results also show that the distribution of building fires varies markedly across the SEQ region, with some of the Brisbane inner suburbs, areas of high socio-economic disadvantage, and parts of inland SEQ associated with relatively high fire rates.     

论寨峁梁房址的建造、使用和废弃

2014至2015连续两年的考古工作,清理了晋陕高原上目前揭露最为完整的一处龙山时代石城聚落——榆林寨峁梁遗址。本文以寨峁梁遗址材料为基础,尝试复原龙山时代以窑洞为主体建筑的前后室房址的建造过程和使用情况,并着重探讨了寨峁梁前后室房址的废弃时间和废弃原因。通过与中国北方地区发现的史前窑洞的比较,作者认为,以寨峁梁为代表的前后室房址是窑洞式居址的复合结构和高级形态,半地穴覆顶的前室应为起居空间,掏挖于生土中的窑洞为卧室。根据灶址的使用和室内器物的相关情况推测,寨峁梁聚落当废弃于夏秋季节,其废弃原因可能与社会动荡引起的冲突事件相关,寨峁梁龙山先民系突发性的自行迁移。     

Mine blast vibration response spectrum for structural vulnerability assessment: case study of heritage masonry buildings

Ground-borne vibrations induced by mine blasting are typically of low amplitudes, which are not considered a major concern for modern engineered structures. However, historic structures are often considered more vulnerable due to inadequate knowledge regarding the state of construction materials and structural response. Specifically, the construction materials used might be fragile or have deteriorated to a stage that could be vulnerable to such vibrations. Simplistic rule based on peak ground motion parameter has been adopted worldwide for safety assessment, while the frequency characteristics of vibrations are not taken into account. Further, there is very limited study on response of heritage structures to near-field blasting. This article presents a practical structural vulnerability assessment method for mine blast-induced vibrations. In particular, a design response spectrum model is proposed based on close range measurements of nearby mine blasting, which is compared with an existing design spectrum model for far-field mine blasts and a typical design spectrum model for earthquake actions. The method is illustrated through a case study of heritage masonry buildings in Australia. The unique blast data presented and the generalized methodology would be useful to both structural engineers and blast engineers in considering potential effects of blasting on heritage structures.     

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.     

The modernity of nations. A tribute to Walker Connor

To fully appreciate Walker Connor's contribution to the foundation of the contemporary study of nationalism, two main factors must be taken into account. First, the context of positivist behavioural political science within which in the late 1960s and throughout the 1970s, he articulated his critique of the concept of nation‐building. In this context, Connor emerged as a critic of the limitations and the naivité of positivist modernization theory. His dissenting voice called for critical rethinking and revision of the central concepts of the theory of political development, some of which enjoyed almost doctrinal status. Second, despite his criticism of modernization theory, Connor retained a strong conviction that nations and national sentiment were the products of modernity; indeed, in his judgement, they formed the primary content of modernity. This too was a critical stance within the rising tide of nationalism studies since 1989–1990, when ideology and wishful thinking influenced to a considerable extent the interpretation of nationalism. Walker Connor's intellectual legacy should thus be understood as a heritage of critical thought that is informed by a noteworthy awareness of the moral responsibilities of scholarly analysis.     

Museums,memory and meaning‐creation: (re)constructing the Tajik nation

To overcome the traumas of the 1992–1997 civil war, the Tajik authorities have turned to history to anchor their post‐independence nation‐building project. This article explores the role of the National Museum of Tajikistan, examining how the museum discursively contributes to ‘nationalising’ history and cultural heritage for the benefit of the current Tajik nation‐building project. Three main discursive strategies for such (re)construction of Tajik national identity are identified: (1) the representation of the Tajiks as a transhistorical community; (2) implicit claims of the site‐specificity of the historical events depicted in the museum, by representing these as having taken place within the territory of present‐day Tajikistan, thereby linking the nation to this territory; and (3) meaning‐creation, endowing museum objects with meanings that fit into and reinforce the grand narrative promulgated by the museum. We conclude that the National Museum of Tajikistan demonstrates a rich and promising, although so far largely unexplored, repertoire of representing Tajik nationness as reflected in historical artefacts and objects of culture: the museum is indeed an active participant in shaping discursive strategies for (re)constructing the nation.     

Hornell,Hasslöf and Boatbuilding Sequences

Hornell's publications on ‘native watercraft’ form a unique ‘library’ dealing with boatbuilding and boat use. His quest for the origins of water transport, on the other hand, was unsuccessful. In a clarification of the issues involved, Hasslöf criticized Hornell's use of the term ‘carvel’ and proposed ‘shell‐first’ and ‘skeleton‐first’ as best able to characterize boatbuilding traditions. Those terms subsequently gave way to ‘plank‐first’ and ‘frame‐first’. Certain north‐west European vessels, each built in both those sequences, were identified by Hasslöf as a link between ‘plank‐first’ and ‘frame‐first’. Such a transition would have been facilitated by the use of ‘framing‐first’, a building sequence used in north‐west Europe and in the eastern Mediterranean from the early 1st millennia AD.     

Borders and banknotes: the national perspective

Replacing a banknotes series is meaningful for politicians and the general public even today, while most transactions are executed through virtual means. The choice of images carried on banknotes represents the limits of the State's sovereign border and becomes a means of banal nationalism. Moreover, by utilising scopic regimes, the hegemony portrays the cultural and political borders: historical figures from the country's past on one side, and an imagined or physical border, expressed through the illustrations on the back. This paper addresses the latter and examines the case of the State of Israel. The analysis of sites and landscapes that appear on national banknotes can decipher the construction process of a ‘territorial identity’ which, along with struggles for maintaining identity, provides the basis of the nation‐state. Using Williams's typology of selective tradition, we argue that Israeli banknotes demonstrate a mixture of residual and new cultural content.
