Sardinia was affected by an intense igneous activity which generated calc-alkaline products during the Oligo-Miocene period. The volcanic substance shows large variations, ranging from pyroclastic flow deposits, lava flows and domes. By composition, the deposits are all primarily dacites and rhyolites, with subordinate andesites and very scarce basalts. The rhyolite lavas show porphyritic and ash-flow tuffs. Ignimbrite structures are found in the dacitic domes and rhyolitic lavas. These rocks—commercially known as “Trachytes of Sardinia”—used to be quarried in all historical provinces, mainly in the central part of the island to be used as ornamental and building stone. They continue to be commonly used nowadays, but their use dates back to the prehistoric age. They are easily found in many nuraghi, “domus de janas”, holy wells, Roman works (mosaics, paving, roads, bridges), many churches built in Sardinia and practically in all kinds of structural elements in public and private buildings, such as walls, houses, and bridges. Contrary to the granitoid rocks, whose appearance is largely influenced by the mineralogical composition, the aesthetic feature of volcanic rocks is rather affected by the widest range of colors, structure and texture, i.e., shape, size and distribution of mineral components, porphyric index, etc. “Trachyte” is quarried opencast with the “single low step” method, with descending development, with prevalent use of double-disc sawing machines. Whenever the stone deposit allows higher steps, the chain cutting machine, in combination with diamond wire, becomes the preferred extraction solution. This study aims to at look Sardinian “trachytes” from a geoheritage perspective. After a geological-petrographic framework, the paper discusses the historical uses of “trachyte” in Sardinia. The current state of the art of “trachyte” quarrying, processing and usage in the Island is also described. An analysis of the “trachyte” production has been carried out. Finally, a consideration about how to enhance geotourism in the area is suggested.

The Aesthetic

Considers the aspects of architecture as a language able to express the current state and to prophetically indicate the upcoming changes. The aesthetic value of a construction cannot be perceived just as a separate entity, but it can be cognized in the context and not only a visual one, in space. It is necessary to see the entire complex of the accompanying phenomena, all the flow of the unfolding metaphors and values. In the model in view the figure of the author-creator must be reconsidered as no longer conforming to today's reality. The development of the Stalinist Empire style, as well as its transformations, is considered as one of the specific phenomena in the history of well-known constructions

Purpose This paper aims to identify the current state of the Portuguese tourism, its opportunities and challenges based on the conclusions of the International Tourism Forum (ITF)/Worldwide Hospitality and Tourism Themes (WHATT) Round Table attended by representatives of the main public and private entities of the tourism sector in Portugal. Design/methodology/approach This paper presents and discusses the main conclusions resulting from the ITF/WHATT Round Table. The event was organized by the Institute for Tourism Planning and Development, under the theme “Tourism in 2016: from trends to results”. Findings The ITF/WHATT Round Table concluded that the tourism industry worldwide and in Portugal, in particular, is facing major challenges that call for innovative ways of managing the tourism experience. On the other hand, world tourism growth was seen as a reality that will remain, and destinations will have to continue working to achieve better tourists instead of getting more tourists. Practical implications This analysis provides knowledge about the current state of the Portuguese tourism, its challenges and opportunities while identifying innovative ways and likely solutions to improve the experience of tourists visiting Portugal. Originality/value The profiling of the current state of the Portuguese tourism, its opportunities and challenges contributes to the design of more effective strategies to improve the Portuguese tourist offer and the experience of tourists visiting Portugal.

This article provides an overview of the current state of and future prospects for children's television in the Federal Republic of Germany. It begins with a brief description of current television provision for children, and of children's viewing patterns, and it suggests that views of children's relations with the medium are heavily influenced by social class. The article goes on to describe the structural features of broadcasting and of media regulation in Germany, paying particular attention to the federal structure and the balance between public and private. The implications of this situation for children's programming are then analysed, with particular attention paid to the heavy regulation of advertising on free-to-air channels, and the need to protect children's slots in the context of a general move towards specialist channels. The article concludes by outlining the terms of recent public debates about the social purpose and quality of children's television.

This chapter presents the current state and future prospects of, and policy issues related to the mobile (m-) government in Turkey at both national and local government levels with a special emphasis to mobile phones. To this end, ?rst, the historical development and major actors of Turkey’s mobile technology market are examined. Following this framework, the current state of government information and services provided by the help of mobile technologies (m-government) is analyzed. Third, several issues related to m-government policy such as health problems that are thought to be caused by mobile phone use and the proximity of mobile phone masts to housing units; the risky behavior of talking via mobile phones while driving and the problems caused by this reckless behavior; problems related to stolen and unregistered mobile phones; and ?nally, the blurring of public and private spheres because of mobile phone use in public places are discussed. Proposed and enacted national legislation on these topics are summarized and discussed. The ?nal section evaluates the future prospects of m-government and integration of electronic government and mobile goverment efforts in Turkey. This section also assesses the possibility of using m-government as a tool for bridging the digital divide in Turkey.

This paper aims to reveal the attitudes of internal auditors, towards overall internal audit practices in the post-communist country of Albania. The study presents the current state of internal audit practices in Albania from eyes of the internal auditors themselves. The study will explore the independence of the internal auditors, the level of professionalism they exhibit, the use of international standards, and whether current regulations are resulting in higher quality work in the profession. In order to study these objectives, a 169-person questionnaire was conducted, all participants where internal auditors from public and private sectors in Albania. The research findings of the study reveal that internal auditors can be assessed as independent in Albania, and that the private sector is the most independent. Regarding professionalism, internal auditors are able to detect and prevent fraud in companies. In this paper, we examine the international standards of auditing that are used by Albanian auditors; the international standards are really useful for internal auditors in Albania, even though there is much room for improvement. The number of participants was limited of 169 and analyzed one country. For the future researches questionnaire can be conducted more than one country to have comparative analysis. One improvement needed is the adaptation of the international standards in national regulations. This will make the international standards easier to apply and understand the standards in Albania.

The second edition of The Oxford Handbook of Interdisciplinarity constitutes an update and revision of a topic of growing academic and societal importance. Interdisciplinarity continues to be prominent both within and outside academia. Academics, policy makers, and members of public and private sectors seek approaches to help organize and integrate the vast amounts of knowledge being produced today, both within research and at all levels of education. This compendium is distinguished by its breadth of coverage, with chapters written by experts from multiple networks and organizations, on topics ranging across science and technology; social sciences, humanities, and arts; and professions. The volume is edited by respected interdisciplinary scholars and supported by an international advisory board to ensure the highest quality and breadth of coverage. The Oxford Handbook of Interdisciplinarity provides a synoptic overview of the current state of interdisciplinary research, education, administration and management, and problem solving—knowledge that spans the disciplines and interdisciplinary fields while also crossing the boundary between the academic community and society at large. Offering the most broad-based account of inter- and transdisciplinarity to date, its essays bring together many of the globe’s leading thinkers on interdisciplinary research, education, and institutional parameters as well as reflections on how knowledge can be better integrated with societal needs.

State Of The Field

This collection of forty original essays reflects on the history of adaptation studies, surveys the current state of the field, and maps out possible futures that mobilize its unparalleled ability to bring together theorists and practitioners in different modes of discourse. Grounding contemporary adaptation studies in a series of formative debates about what adaptation is, whether its orientation should be scientific or aesthetic, and whether it is most usefully approached inductively, through close analyses of specific adaptations, or deductively, through general theories of adaptation, the volume, not so much a museum as a laboratory or a provocation, aims to foster, rather than resolve, these debates. Its seven parts focus on the historical and theoretical foundations of adaptation study, the problems raised by adapting canonical classics and the aesthetic commons, the ways different genres and presentational modes illuminate and transform the nature of adaptation, the relations between adaptation and intertextuality, the interdisciplinary status of adaptation, and the issues involved in professing adaptation, now and in the future. Embracing an expansive view of adaptation and adaptation studies, it emphasizes the area’s status as a crossroads or network that fosters interactive exchange across many disciplines and advocates continued debate on its leading questions as the best defense against the possibilities of dilution, miscommunication, and chaos that this expansive view threatens to introduce to a burgeoning field uniquely responsive to the contemporary textual landscape.

Chemical And Mineralogical Composition

The term gneiss as generally used by geological writers signifies a rock of granitic composition in which a parallel structure in the arrangement of the constituents is more or less apparent. For our present purpose it is important to note that other plutonic rocks besides granite (e.g. diorite, gabbro, and peridotite) have their gneissose equivalents, so that, if we use the term gneiss in a structural rather than in a mineralogical sense, we may speak of diorite-gneiss, gabbro-gneiss, and so on. Now the parallel structure of gneissose rocks is of two kinds. It may consist (1) of a parallel arrangement of certain constituents (e.g. mica plates or porphyritic felspars), or (2) of an alternation of bands of varying chemical and mineralogical composition. It is agreed on all hands that a parallel structure of the first kind may be due either to the deformation of a mass of half-consolidated plutonic rock at the time of intrusion, in which case it is strictly analogous to the flow structure in many volcanic rocks, or to deformation produced by earth-stresses operating on the mass after consolidation.

Meguma Terrane

Eight short drill cores have been examined from the continental shelf southwest of Nova Scotia. Four cores recovered granitoid rocks of two types. Ilmenite-bearing granitoid rocks petrographically and geochemically resemble granodiorites of the South Mountain Batholith and granites of the Seal Island Pluton. Magnetite-bearing granitoid rocks are also peraluminous but have no exact analogues onshore in Nova Scotia. Two cores recovered metamorphic rocks in a small area 50 km south of Seal Island. One consits of chlorite–muscovite–quartz schist, geochemically similar to rocks of the Halifax Formation. The second sampled epidote–chlorite–quartz schist similar to metavolcanic rocks of the White Rock Formation. One further core sampled quartzite, and another sampled a metavolcanic rock (possibly erratic).The regional extent of these lithotypes can be inferred from gravity and aeromagnetic data. Regional gravity data suggest the presence of a large granite body off southwestern Nova Scotia. In this area, magnetic anomalies are irregular, apparently reflecting the presence of magnetite-bearing granites. The layer-stripping method of analyzing the magnetic field shows that the area is underlain at depth by high magnetic anomalies. Large near-surface linear magnetic anomalies are used to map the extent of the volcanic rocks of the White Rock Formation. The area is cut by several northwest-trending faults that postdate Acadian folding but predate the earliest Jurassic magmatism of the Shelburne Dyke and North Mountain basalt. The unusual magnetic signature of the area off southwestern Nova Scotia may reflect a different basement; it is possible that Meguma rocks are thrust over the Avalon Terrane. Alternatively, it may be solely the result of magnetite-bearing granites. These granites may be related to a Permian thermal event in southwest Nova Scotia, and they have some petrographic similarity to young granites of the Piedmont Zone of South Carolina.
