There is considerable interest in the potential of bat guano as an alternative record of palaeoclimate in regions that are devoid of more commonly utilised archives. In this study, designed originally to evaluate the potential of cave hosted bat guano to preserve temporal variations in the flux of cosmogenic 36Cl, it was found that the guano depositional history is strongly linked to climatic conditions. Radiocarbon measurements on a 2.7 metre long core of bat guano from Măgurici Cave, N.W. Romania indicate a maximum depositional age of 1195 AD for the base of the core. Deposition of the lowermost portion of the accumulation occurred during the Medieval Climate Anomaly. The cave roost was subsequently devoid of bats during a regional cold phase linked to the Little Ice Age, with bats returning when local temperatures increased. The rate of guano accumulation then appears to increase in tandem with anthropogenic warming. This indicates that bat occupation at this roost site in Măgurici Cave is strongly linked to regional climate variability, with habitation during warm periods, possibly associated with the abundance of insects upon which the bats feed.
Comparison of large peaks in anthropogenic 14C and 36Cl production associated with nuclear weapons testing indicates downward migration of 36Cl, probably reflecting post-depositional migration within the guano deposit. Elevated 36Cl/Cl at the top of the core in comparison with modern atmospheric values may indicate recycling of bomb 36Cl in vegetation. Therefore, we show that while bat guano contains abundant atmospherically-derived chloride it has severe limitations as a potential archive of atmospherically-derived 36Cl (a solar proxy), because of post-depositional mobility. However, separation of organically bound chloride, or the use of an alternative cosmogenic isotope 10Be, in bat guano, may offer an unexploited solar proxy that contains contemporaneous environmental signals, such as stable isotopes (e.g. δ13C) and pollen, in association with radiocarbon dating.

The study discusses the value of cave guano as a source of palaeoclimate data and tests if guano sequences record the same signals as other proxies (tree rings, speleothems, lakes or peat). The pollen record extracted from Măgurici Cave guano is consistent with the known vegetation history during the Late Subatlantic period, exhibiting two climate events: the Medieval Climate Anomaly and the Little Ice Age. Human influence on vegetation is also revealed, especially in modern times, by the decrease of arboreal pollen, the increase of herbaceous taxa related to grazing and the occurrences of cereals. Cave bat guano is emphasized as a source of valuable palaeoclimate data, especially in areas where no conventional archives are available.

The Sibiu 2007 European Cultural Capital (ECOC) was monitored in order to highlight the longterm impacts of the event. Preliminary findings on the tourism impacts are presented based on field research among visitors and statistics and field inventory. The most visible as well as the most significant impact on the city is the growth of accommodation supply. Not only did the number of licensed units and room grow substantially, but there was also considerable growth in
the informal accommodation sector. Not only the city of Sibiu, but also the surrounding region benefited from the ECOC opportunity. The research shows that although the informal sector was able to respond fastest to the growth in accommodation demand, the greatest economic impact
came from the development of large commercial hotels in the city itself.

Denigrating intellectuals and eliminating people that stands out against the ruling government for a public interest cause has deep roots in the old time human behavior tendency to hold power. Personally I have hard time to accept that during our days such concepts and practices are still generalized in the civilized countries. Remainders of the old communist and dictatorial regimes isolated tendencies are possible to linger around. We can aim towards a sustainable development only by reaffirming the democracy, the social contract and the fundamental law protecting the Human Rights. If not absolutely nothing makes sense.

Healthcare is at the foundation of human rights, and all people should benefit. How do you see the health care system regulated as to respect human rights? The instability found in the social contract has to do with healthcare and retirement being secured for people. If there’s instability, it can lead to “civil unrest at different levels.” I think maybe we have seen a little bit of that with the Occupy Wall Street feelings about how society is ordered.

Bessarabia at the End of World War I – The Handbook of the Historical Department, Foreign Office (1919)
Abstract: The paper reproduces the handbook on Bessarabia, the former Russian province united in 1918 with Romania, prepared by the Historical Department of the Foreign Office for the use of the British delegation at the Paris Peace Conference of 1919. The handbook is an extremely important source for all aspects related to modern Bessarabia, from historical or geographical data to the social and economic realities in the province. The text proper is preceded by a short historical comment on the activity of the Historical Department of the Foreign Office in 1919-1920.

This paper takes stock of academic literature and official sources on post-accession compliance in Bulgaria and Romania, the only new member states where the Commission has preserved the right to monitor key reforms following accession. The data used in the analysis suggests that formal compliance with EU law has not decreased since their accession. Quite the contrary; Bulgaria and Romania have performed well with regard to the transposition of EU law, yet signs of shortcomings have appeared at the enforcement level, possibly on a greater scale than in other CEECs. Moreover, it is argued that in the first years of membership, the Commission’s post-accession monitoring did not yield the same results in Bulgaria and Romania. While Romania has managed to convince the Commission of its good will and determination to meet the benchmarks set by the EU, Bulgaria has failed to do so and has
faced sanctions in relation to the EU’s extended conditionality. The analysis concludes by presenting possible directions for further research.

Spacer plates made of clay - A contribution to the Wietenberg Cultures adornments
For the Wietenberg Culture, until now, nearly nothing was known about dressing habits, as
the few bronze and bone adornments surviving come mainly from settlement sites. Little attention
was paid to spacer beads made of clay, of which three are known, including a new find from the
settlement of Rotbav. Their function as spacer beads in a complicated necklace arrangement can be
deduced from an anthropomorphic statuette found at Satulung-Finteuşul Mic, which has to be
contemporaneous with the Wietenberg Culture judging from the depicted bronze ornaments, which
are to be found in the same combinations in hungarian bronze hoards and, partly, as single finds in the
Wietenberg area. Further the article discusses a possible relation between the clay spacer beads and
those made of amber. Similar necklace arrangements with amber spacer beads are known from
southern Germany, but not from Greece, an area often employed as source of origin for inventions
(like „mycenaean“ swords and spiral decoration) in the Wietenberg area.
