Scientific heritage: Reflections on its nature and new approaches to preservation,study and access

Scientific heritage can be found in every teaching and research institution, large or small, from universities to museums, from hospitals to secondary schools, from scientific societies to research laboratories. It is generally dispersed and vulnerable. Typically, these institutions lack the awareness, internal procedures, policies, or qualified staff to provide for its selection, preservation, and accessibility. Moreover, legislation that protects cultural heritage does not generally apply to the heritage of science. In this paper we analyse the main problems that make scientific heritage preservation so difficult to address. We discuss the concept and present existing preservation tools, including recent surveys, legislation, policies, and innovative institutional approaches. We briefly analyse two recent initiatives for the preservation of scientific heritage, at the Universities of Lisbon and Cambridge.     

Two new species of Phylactella (Bryozoa Cheilostomatida) from the Mediterranean area belonging to the P. labrosa (Busk) complex of species

Examination of fossil and Recent specimens from the Sicilian area belonging to the Phylactella labrosa ‘complex’ revealed two new species: P. mediterranea sp. nov., a Pleistocene-to-Recent taxon and P. megarensis sp. nov., from Pleistocene sediments from eastern Sicily. Ecological, geographical and stratigraphical distribution of both new species are discussed also in comparison with P. labrosa.     

The identity of Yoldia micrometrica Seguenza, 1877 and three new deep-sea protobranchs from the Mediterranean (Bivalvia)

Three new species are described from the relatively well-known deep Mediterranean protobranch fauna. Yoldiella wareni n. sp. is a miniaturized species so far misidentified as Yoldiella micrometrica (Seguenza, 1877), which is a Pleistocene species (neotype here designated). Yoldiella ovulum n. sp. is similar to Y. micrometrica, of which it may represent a descendant species. Ledella marisnostri n. sp. is the second species known for the genus in the Mediterranean. These three species are thought to be endemic to the Mediterranean, where they may represent either persisting Plio-Pleistocene species which survived the changes from psychrospheric to homeothermic conditions, or newly adapted species, evolved from Plio-Pleistocene ancestors. In the second case, they seem to be the result of an ongoing differentiation of the deep Mediterranean protobranch fauna from the North-East Atlantic one, due to the physical isolation of the Mediterranean basin.

本文通过对苏南地区(包括上海市)的地貌第四纪、历史文物、升降运动、河道和湖泊变迁、历史地震、地形变化、断裂及岩浆活动的资料和野外查证,将本区分为四个分区,最后指出茅山山体及茅东至宜溧地区是活动性较强、地震相对较活动的地区。     

Amphiblestrum Gray, 1848 (Bryozoa Cheilostomatida) from the Atlantic-Mediterranean area,with description of a new species

Several species, belonging to the genus Amphiblestrum Gray from the Atlantic-Mediterranean area are discussed. One species is described as new: A. frigidum sp. n., from Lower Pleistocene sediments of the Mediterranean area and from the Recent Northern Atlantic. Systematic affinities among species are discussed together with geographical, ecological and stratigraphical distributions. The climatic-palaeoclimatic significance of some species is stressed: A. lyrulatum and the fossil A. spaeleus and A. intermedius seem to be warm-temperate species whereas all the others are cool, boreal or boreal-arctic species. A. flemingi and A. frigidum sp. n., both Recent Northern Atlantic species known from Würmian submerged sediments and/or Lower Pleistocene outcrops of the Mediterranean area are considered as Boreal Guests.     

生与死的辩证法——论方方近期小说对生存哲学的思考

方方对死生这个哲学命题的思考,已经融入了她的创作中,而在不同的创作时期,作家对死和生的态度也并不相同。如果说在＂新写实＂时期,方方以死亡为视角,以零度写作的叙述态度来窥探生存的琐屑和人性的卑微、丑陋,那么在她近期的作品中,她则以人道主义视角为我们还原了人类生存的本相。方方在创作中,关注的焦点、叙述态度和哲学思考都出现了转向。这三个方面的转向分别是：从消解生命的价值到对生命韧性的关注;从悲情主义到温情主义;从存在主义到人道主义。
