The question of authenticity in recoveries in post-conflict zones

In most of military conflicts the cultural heritage is being deliberately destroyed. Two main aspects of its destructions are direct and indirect. In the direct destruction the tangible aspects of the monuments are being damaged or destroyed, while indirect destruction of the monument attacks its values – its general context (for instance during the significant demographic changes in the region where the monument is situated, or during the changes of the ideological climate, etc; the monument physically is not changed but its meaning does). When it comes to the recovery of monuments in post-conflict period, most often there are multiple issues. Sometimes the monument can be perfectly restored in its physical aspect, but its intangible aspect (its significance) can remain deformed, which, consequently, affects the perception and the interpretation of the monument. In what measure this incomplete recovery affects the entire monument? Recently in monument protection domain the question of authenticity is being raised, particularly now for the occasion of 20th anniversary of Nara Document on Authenticity, and it is the focus issue of this paper in context of military-conflict related cases. The paper focuses on the case studies of performed recoveries of important monuments in post-conflict zones and it analyzes the success of these recoveries pointing out the authenticity. It also turns on the what way the communities should contribute to the recovery of damaged recoveries (the Nara Document emphasise the importance of social inclusion in the monument protection). The paper features the case studies trying to interpret different aspects of a monument: its material and intangible aspects and their relation. Other documents that this paper relies on is the International Charter for the Conservation and Restoration of Monuments and Sites (the Venice Charter), World Heritage Convention, Operational Guidelines for the Implementation of the World Heritage Convention etc.

Post T Tauri stars in the solar neighborhood: isolated or members of young associations and moving groups

Post T Tauri stars (PTTS) are late-type stars in the age range between 10 and 100 Myr filling the gap between T Tauri (TTs) and zero-age: main sequence phases. This period of evolution remains ambiguous and until now different studies of young stars have failed to find the numbers of PTTS that are expected. In the last years, some PTTS have been identified among the X-ray detected pre-main sequence stars in some star-forming regions. More recently, additional PTTS have been identified in young associations and moving groups (β Pic, TW Hya, Tucana/Horologium, and the AB Dor). However, many isolated PTTS still remain undiscovered. In this contribution, we compiled the PTTS previously identified in the literature, and identified new candidates using the information provided by the high resolution spectra obtained during our surveys of late-type stars possible members to young moving groups, FGK stars in the solar neighborhood, and RasTyc sample. To identify PTTS we applied an age-oriented definition using relative age indicators (Li abundance, chromospheric and coronal emission and the kinematics) as well as color-magnitude diagrams and pre-main sequence isochrones.
