Promoting tourism through the EU LEADER programme: understanding Local Action Group governance

ABSTRACT

For many European rural areas, the rural development programmes based on the LEADER approach constitute the main policy for promoting tourism. Going a step further than a rural development programme, LEADER represents an ideal method for overcoming some of the challenges involved in rural tourism development, such as the integration of tourism supply through public-private organizations or the coordination of multi-level policies. Despite its potential, there are difficulties involved in putting this approach into practice. This article aims to provide in-depth understanding of the challenges faced by some managers responsible for developing tourism strategies through the LEADER approach. To do this, semi-structured in-depth interviews have been held with Local Action Groups managers from Castilla-La Mancha (Spain). The main findings reveal that the actions of regional governments lead to the limitation and strangulation of the principle of subsidiarity according with the LAG manager? opinion.     

Assessment Techniques for Studying the Effects of Fire on Stone Materials: A Literature Review

ABSTRACT

Fire is one of the most severe threats to stone applied in civil engineering and architecture. In most cases, its effects are irreversible and have long-lasting repercussions. In addition to aesthetic alterations, fire can also induce important mineral-chemical, physical, and mechanical changes in stone. Research concerning the effects of fire on stone materials in recent decades has been providing valuable knowledge to inform present and future conservation and restoration actions. In this literature review, the properties and techniques used for studying the effects of fire on stone materials are appraised, summarized, and compiled. A comprehensive and practical overview of those effects is also given. Open porosity and P-wave ultrasonic velocity are the physical and mechanical properties that have been studied most. Other frequently researched areas include chemical-mineralogical changes, color, density, water absorption, uniaxial compressive strength, and modulus of elasticity are also very frequently investigated.     

Open Warfare or the Odd Skirmish? Bell Beaker Violence in the North‐Eastern Iberian Peninsula

Archaeological examples of violence in prehistory have increased in recent years. The evidence, methodology employed and interpretation of the data have been diverse, but in each case the myth of the ‘peaceful past’ is questioned. This work provides new data on the issue from the north‐eastern Iberian Peninsula, associated with the Bell Beaker culture (c.2800–2350 cal BC). Material from two megalithic tombs, Can Gol I and Can Gol II (Barcelona Province), in particular a set of flint arrowheads, has been revisited. Use‐wear analysis on the arrowheads confirmed the presence of impact fractures. This indicates that the arrowheads were not funerary offerings, but that they entered the graves lodged in the bodies of the deceased. The data from the only site with evidence of massive death by violence in the neighbouring region (Costa de Can Martorell) reinforce the hypothesis of episodes of conflict and violence during prehistory. However, the interpretation of the nature of such violence remains open to debate: was it an act of warfare or an occasional skirmish? And is the image of the Bell Beaker warrior identified in other European contexts also applicable to this area?     

陕西境内遗址表面CaSO42H2O产生之水盐运移规律研究

陕西境内遗址出土后短时间内表面产生白色物质CaSO₄2H₂O是非常普遍的现象。本研究利用土柱模拟遗址出土后表面产生CaSO₄2H₂O的过程,通过监测土柱中土壤的湿度、含盐量及离子变化综合分析CaSO₄2H₂O产生的原因,研究结果表明遗址出土后形成了新的界面层,在蒸发的作用下,地下水沿土壤孔隙向上迁移,同时将可溶盐带入土壤中,表面的可溶盐含量逐渐增大,达到峰值后不再增加,实验后测得表面土壤中的Ca²⁺和SO2-₄是原始土壤的数十倍,说明遗址表面产生CaSO₄2H₂O是水盐运移的结果。本研究可为遗址出土后预防CaSO₄2H₂O的产生提供依据。
