Middle–Upper Jurassic marine gastropods from central Saudi Arabia

Ferrari, M., El-Hedeny, M., Zakhera, M., El-Sabbagh, A. & Al Farraj, S., May 2018. Middle?Upper Jurassic marine gastropods from central Saudi Arabia. Alcheringa.

A total of 68 gastropod specimens are reported from the Middle?Upper Jurassic sedimentary successions exposed at central Saudi Arabia. The studied material comes from the Tuwaiq Mountain and Hanifa formations at the Khashm al Qaddiyah, Dirab, Jabal al Abakkayn and Maáshabah sections. Thirteen species are identified, described and illustrated. Among them, a new Aporrhais species (A. sauditica sp. nov.) is introduced. In addition, two further possible new Pseudomelania species from the same strata are mentioned. Other members of the assemblage include Kosmomphalus? sp. aff. K. reticulatus Fischer, Bourguetia? sp. aff. B. saemanni (Oppel), Bourguetia? sp., Ampullospira sp., Globularia? sp. cf. G. bajociana Fischer, Purpuroidea sp. aff. P. glabra Morris and Lycett, Purpuroidea sp., Cossmannea sp. aff. C. desvoidyi (d’Orbigny), Cryptoplocus sp. aff. C. depressus (Voltz) and Actaeonina? sp. Stratigraphically, seven species of this gastropod assemblage were only reported from the Middle Jurassic, whereas the other six ones are extending from the Middle to the Upper Jurassic of the studied succession. As compared with their gastropod content, the Khashm al Qaddiyah represents the richest section (33 out of 68 specimens, 48.5%), whereas the Maáshabah section showed an impoverished gastropod assemblage (only three specimens, 4.4%). The species reported here show paleobiogeographical affinities with coeval gastropod assemblages from India, east Africa, Middle East (Israel, the Sinai of Egypt) and western Tethys. The identified species confirm three depositional settings: open shelf lagoon, shoal/fore-shoal and open marine environments. The lower degree of fragmentation, poor sorting and scarcity of abrasion indicate a parautochthonous faunal assemblage.

Effects of a New Hydrological Barrier on the Temperatures in the Organic Archaeological Remains at Bryggen in Bergen,Norway

The World Heritage Site of Bryggen in Bergen, Norway, has experienced significant degradation of archaeological deposits as a consequence of changes in the soil water and groundwater balance after urban redevelopment adjacent to the heritage site. Additionally, groundwater temperatures below the heritage site were found to be significantly higher closer to the redeveloped area. One of the main mitigation measures taken to reduce the degradation of the archaeology has been the construction of a hydrological barrier along the sheet piling that divides the redeveloped area and the historic site. A shallow subsurface infiltration system was designed to achieve groundwater levels and flow conditions that are optimal for the preservation of archaeological remains directly along the sheet pile, while reducing drainage and subsidence also further upstream. Monitoring of groundwater level and temperatures after implementation of the hydrological barrier shows that groundwater levels and flow conditions have improved with respect to optimal preservation conditions, and groundwater temperatures have generally been reduced by up to 2 °C.     

A case of local rejection of a heritage tourism policy: tourism and dynamics of change in Abondance,French Alps

Despite the opportunities offered by developing and enhancing cultural heritage in the tourism sector, this article, based on a case study of a little town in the French Alps, shows that public policy of this type may also be subject to criticism and dispute. In the town of Abondance, a small ski resort being converted to cultural tourism site built around heritage, the demonstration observed involved both a desire to keep the skiing and a questioning of the political process, but also a rejection of the alternative solution involving the development of the cultural heritage of the Gothic Court of Savoy. During the qualitative survey of the social reactions, three types of arguments have been raised. (1) As summarised by one of the local leaders ‘the people do not believe in it’. Indeed, local shopkeepers are sceptical that cultural tourism will draw numerous visitors, and fear that is not economically viable. (2) In contrast to the ski resort, heritage tourism is only attached to the imagination of old age, immobility and even death, as if seniority of places necessarily corresponds to seniority of public and images. (3) For residents of the town, setting up a localised visit site has disadvantages because of the turnover of touristic traffic to which this type of tourism is exposed.     

Implementation of Sustainable Urban Drainage Systems to Preserve Cultural Heritage — Pilot Motte Montferland

The shallow subsurface in historic cities often contains extensive archaeological remains, also known as cultural deposits. Preservation conditions for naturally degradable archaeological remains are strongly dependent on the presence or absence of groundwater. One of the main goals at such heritage sites is to establish a stable hydrological environment. Green infrastructural solutions such as Sustainable Urban Drainage Systems (SUDS) can support preservation of cultural deposits. Several cases show that implementation of SUDS can be cost effective at preservation of cultural deposits. These include Motte of Montferland, City mound of Vlaardingen, Weiwerd in Delfzijl, and the Leidse Rijn area. In all cases, the amount of underground infrastructure is minimised to prevent damaging cultural layers. SUDS have been implemented to preserve cultural heritage. The first monitoring results and evaluation of the processes give valuable lessons learned, transnational knowledge exchange is an important element to bring the experiences across boundaries.

Masculinity and Secessionism in Italy: An Assessment

Abstract. The masculinist rhetoric of the northern Italian separatist party, the Lega Nord, is an example of nationalist status affirmation. The stereotyped contrast between effeminate southerners and masculine northerners developed at the end of last century is used to affirm the superiority of the masculine North. The Lega's rhetoric parallels mainstream concerns on Italy's international status, and proposals for reforms to make Italy more ‘masculine’ and European. The use of a gendered language for the affirmation of national status reveals a belief in a normative hierarchy of nations, but also introduces a tension between a ‘masculinist’ status affirmation and a model of modernity which includes the emancipation of women as one of its principles.     

Dynamical Behavior of Cellular Automata under the Constraint of Neighborhood Coherence

The emergence of spatial discrete patterns has attracted little research interest among geographers, especially as far as the phenotypical aspects of the pattern are concerned. How can we understand the development of such patterns? What role is played by generative rules underlying this process? Using the cellular automata theory, a model (SISPAQ) was built to probe into the role of the neighborhood coherence principle (NCP) as a generative rule. Several remarkable properties of NCP are unveiled. A self-organizing behavior is shown, which allows the system to counteract the maximum entropy law and build a pattern with a relatively high level of organization. Not only does NCP provide sufficient conditions for the building up of an organized pattern, but it also provides a self-maintaining capacity. This is evidenced by the fact that under a critical value (the emancipation probability), any cell or group of cells displaying an aberrant state will be eradicated by a locally dominant state.     

The Little Nyonya and Singapore’s national self: reflections on aesthetics,ethnicity and postcolonial state formation

Singapore’s postcolonial state formation process has combined the appeal/distress of a multiracial society with the nationalistic pride of economic development. In recent years, the city-state has witnessed a revival of Peranakan culture and history, referring to the descendants of early Chinese immigrants who integrated into Indigenous societies before becoming prized mediators for British colonisers in the nineteenth and twentieth centuries. We question how these references are strategically deployed as part of the process of postcolonial state formation and how their aesthetic representations support public discussions and debates about what defines contemporary (Chinese) Singaporean identity. By examining Peranakan representations in the television series The Little Nyonya from a Deleuzian perspective, it will be argued that Peranakan history and culture are mobilised to de-territorialise previous meanings of national ethnic markers, specifically Chineseness, and to re-territorialise a local sense of Indigeneity. In reaction to concerns over Mainlander identity, representations of Peranakan culture and history in The Little Nyonya support the indigenisation of a specific Chinese identity that is accessible to all Singaporeans, offering an aesthetic framework in which the ongoing process of negotiating between Singapore’s national self and other unfolds.
