旅行的意义:大众旅游者自我发展的视角

旅游已成为个体寻求自我发展的一种手段。本文以大众旅游者个体为研究对象,探索旅游对旅游者自我发展的影响及其作用机制。研究运用扎根理论研究方法,对所搜集的资料逐级编码、概念化和范畴化,发现大众旅游者自我认知的变化具有普遍性,构建了旅游者情境自我发展过程的框架,最终得到核心范畴——旅游者自我发展。研究发现,旅游者在旅游过程中或结束后对自我的内省能够促进自我发展;影响旅游者内省行为的两条路径分别是情绪过程和意志过程;情绪过程受到旅游者对旅游情境因素的知觉和出游动机的双重影响;意志过程主要受旅游者出游动机的影响。     

Hydrogeological Knowledge from Below: Water Expertise as a Republican Common in Early-Modern Venice**

This essay looks at early-modern Venice hydroculture as a case of episteme from below. The forms of water knowledge it developed were multilayered and collective in their essence and solidly rested on a social experiential basis that was rooted in labour (especially fishing) and practices (especially water surveying and engineering). In accordance with the city's republican esprit (and correspondent political values), its episteme emerged as the encounter and negotiation between various institutions and groups: the fishermen of San Niccolò in Venice, the practitioners of the water magistrature and political authorities. This essay explores the institutional settings of this water culture, seen as an instance of bottom-up epistemic construction. It especially addresses three historical instances: firstly, a seventeenth century program to map public waters in order to block their alienation for private fish farming; secondly, water officers’ interviews with fishermen aimed to assess the state of the lagoon hydromorphology and, thirdly, fishing regulations. Venice communitarian and circular forms of knowledge production are here contrasted to an opposite paradigm, which was embodied by the Galileian mathematician and Rome courtier, Benedetto Castelli. His interactions with the Republic of Venice on water management and his approach to hydraulic problems are revealing of an elitist and abstract understanding of scientific knowledge that guided political decisions from above without taking in any consideration the opinions of the ‘vulgar’. While his science was the expression of a top-down political epistemology, Venetian water knowledge was more egalitarian. It left room for exchange, inclusiveness and bottom-up codification; it valued the gathering of different experiences (including the fishermen's practical knowledge of their waters) and rested on a concrete and systemic (organicist) understanding of natural-anthropic processes.     

Holocene land-use evolution and associated soil erosion in the French Prealps inferred from Lake Paladru sediments and archaeological evidences

A source-to-sink multi-proxy approach has been performed within Lake Paladru (492 m a.s.l., French Prealps) catchment and a 6-m long sediment sequence retrieved from the central lacustrine basin. The combination of minerogenic signal, specific organic markers of autochthonous and allochthonous supply and archaeological data allows the reconstruction of a continuous record of past human disturbances. Over the last 10,000 years, the lacustrine sedimentation was dominated by autochthonous carbonates and the watershed was mostly forest-covered. However, seven phases of higher accumulation rate, soil erosion, algal productivity and landscape disturbances have been identified and dated from 8400 to 7900, 6000 to 4800, 4500 to 3200, 2700 to 2050 cal BP as well as AD 350–850, AD 1250–1850 and after AD 1970. Before 5200 cal BP, soil erosion is interpreted as resulting from climatic deterioration phases towards cooler and wetter conditions. During the Mid-Late Holocene period, erosion fluxes and landscape disturbances are always associated with prehistorical and historical human activities and amplified by climatic oscillations. Such changes in human land-used led to increasing minerogenic supply and nutrients loading that affected lacustrine trophic levels, especially during the last 1600 years. In addition, organic and molecular markers document previously unknown human settlements around Lake Paladru during the Bronze and the Iron Ages.     

Egyptian Blue cakes from the Ayanis fortress (Eastern Anatolia,Turkey): micro-chemical and -structural investigations for the identification of manufacturing process and provenance

The microstructure and chemical composition of blue cakes, found during the archaeological excavation of the Ayanis fortress (Eastern Anatolia, Turkey), have been investigated by means of scanning electron microscopy combined with energy dispersive spectrometry (SEM–EDS), X-ray diffraction (XRD), micro-Raman (μ-Raman) and optical microscopy (OM) techniques. The analysis of the Ayanis cakes has shown the presence of Egyptian blue (i.e. CuCaOSi₄O₁₀, cuprorivaite), as the major component, intermixed with minor amount of other phases such as partially reacted quartz grains, an adherent glass phase and copper oxides. Since the finding of Egyptian Blue in Turkey has been never reported so far, great attention has been paid to its characterisation. The micro-chemical and micro-structural investigations of the Ayanis cakes have allowed a further insight into the manufacturing process and into the sources of the starting materials. The results of the characterisation have revealed some significant differences with respect to Egyptian blue cakes found in Egypt and Mesopotamia, as for instance the absence of tin excluded the use of bronze scraps or filings in their preparation differently from those produced in Egypt and Mesopotamia. Furthermore, some peculiarities of Egyptian blue found in Ayanis, as the detection of zinc in the cakes, allow to put forward the hypothesis of a local production considering that a large part of the bronze artefacts found at the Ayanis fortress is characterised by the presence of zinc as minor alloying element.     

First bryozoan fauna from the middle Miocene of Central Java,Indonesia

Di Martino, E., Taylor, P.D., Fernando, A.G.S., Kase, T. & Yasuhara, M. 3 June 2019, 2019. First bryozoan fauna from the middle Miocene of Central Java, Indonesia. Alcheringa 43, 461–478. ISSN 0311-5518.

Despite the publication of several taxonomic studies during the last few years, our knowledge of bryozoans from the diversity hotspot of the Indo-West Pacific remains seriously deficient. Here we describe 11 bryozoan species, comprising two anascan- and nine ascophoran-grade cheilostomes, from the middle Miocene (Langhian–Serravallian) of Sedan in Central Java, Indonesia. Three ascophoran-grade cheilostomes, Characodoma multiavicularia sp. nov. Di Martino & Taylor, Stenosipora? cribrata sp. nov. Di Martino & Taylor and Lacrimula patriciae sp. nov. Di Martino & Taylor, are described as new species. All of the three extant species have an Indo-Pacific distribution today and two are here reported as fossil for the first time. Four species are left in open nomenclature, either because of the scarcity of available material or the absence of crucial morphological features. Two of these, placed in Cosciniopsis and Actisecos, are likely to be new, while Discoporella sp. represents the easternmost known record for this common free-living genus. A single species, Lacrimula asymmetrica Cook & Lagaaij, was already known from the early Miocene of the same region, although from a site further to the east.

Garibaldi and parliamentary democracy

Abstract

The extraordinary nature of Garibaldi's life is reflected in his involvement in parliamentary activities across a number of countries (Uruguay, Kingdom of Sardinia, Roman Republic, Kingdom of Italy, French Republic). After the national unification, Parliament became a kind of great sounding board in Garibaldi's strategy thanks in part to the fact that in the Chamber he could count on a group of followers who were always ready to support any issue vaguely to do with memories of the Risorgimento or irredentist aspirations. His failure to steer the new state in the desired direction through the legislative process certainly influenced Garibaldi's negative opinion of parliamentary work. Garibaldi could not however recognize as an expression of popular sovereignty a parliament in whose election only 2 per cent of the population were allowed to participate. His main political battle was the fight for universal suffrage which was intended to enfranchise all Italians, thus turning subjects into citizens and finally making parliamentary institutions nationally representative and democratically legitimate.
