Abstract The paper states that geodiversity is the abiotic complement to biodiversity, and is considered to be the elements associated with the abiotic environment, e.g. geological diversity, geomorphodiversity, pedodiversity, hydrodiversity and climodiversity. Geoheritage is considered as the geological heritage of a site, but is here presented as the abiotic heritage of a site, and is related to geological heritage, geomorphoheritage, pedoheritage, hydroheritage and climoheritage. Thus, it is possible to talk about geological sites, geomorphosites, pedosites, hydrosites and climosites. Geodiversity and geoheritage are strongly linked to geology. However, it is also a new paradigm to geography, as physical geography classically works with abiotic and biotic environments.

This book uses all the available evidence to create a site biography of Larinum from 400 bce to 100 ce, with a focus on the urban transformation that occurs there during the Roman conquest. Larinum, a pre-Roman town in the modern region of Molise, undergoes a unique transition from independence to municipal status when it receives Roman citizenship in the 80s bce shortly after the Social War. Its trajectory illuminates complex processes of cultural, social, and political change associated with the Roman conquest throughout the Italian peninsula in the first millennium bce. This work highlights the importance of local isolated variability in studies of the Roman conquest and provides a narrative that supplements larger works on this theme. Through a focus on local-level agency, it demonstrates strong local continuity in Larinum and its surrounding territory. This continuity is the key to Larinum’s transition into the Roman state, which is spearheaded by the local elites. They participate in the broader cultural choices of the Hellenistic koiné and strive to be part of a Mediterranean-wide dialog that, over time, will come to be dominated by Rome. The case is made for advancing the field of Roman conquest studies under a new paradigm of social transformation that focuses on a history of gradual change, continuity, connectivity, and local isolated variability that is contingent on highly specific issues rather than global movements.

We are witnessing the development of new communication technologies (e.g., DTV networks [digital TV], 3G [thirdgeneration] telephony, and DSL [digital subscriber line]) and a rapid growth in the amount of information available. In this scenario, users were supposed to benefit extensively from services delivering news, entertainment, education, commercial functionalities, and so forth. However, the current situation may be better referred to as information overload; as it frequently happens that users are faced with an overwhelming amount of information. A similar situation was noticeable in the 1990s with the exponential growth of the Internet, which made users feel disoriented among the myriad of contents available through their PCs. This gave birth to search engines (e.g., Google and Yahoo) that would retrieve relevant Web pages in response to user-entered queries. These tools proved effective, with millions of people using them to find pieces of information and services. However, the advent of new devices (DTV receivers, mobile phones, media players, etc.) introduces consumption and usage habits that render the search-engine paradigm insufficient. It is no longer realistic to think that users will bother to visit a site, enter queries describing what they want, and select particular contents from among those in a list. The reasons may relate to users adopting a predominantly passive role (e.g., while driving or watching TV), the absence of bidirectional communication (as in broadcasting environments), or users feeling uneasy with the interfaces provided. To tackle these issues, a large body of research is being devoted nowadays to the design and provision of personalized information services, with a new paradigm of recommender systems proactively selecting the contents that match the interests and needs of each individual at any time. This article describes the evolution of these services, followed by an overview of the functionalities available in diverse areas of application and a discussion of open problems. Background The development of personalized information

Being an oldest landmass with the most complete Paleozoic rock sequence Langkawi archipelago hosts the richest geological diversity and heritage resources in the country. As a popular tourist destination, the scenic beauty has attracted tourists to Langkawi without them realising that the beauty has been created by the islands’ rich geological heritage diversity. To date more than 90 geoheritage sites of highly significant scientific, aesthetic, social or recreational value have been identified. Some of these geoheritage sites have become popular tourist sites. To ensure the sustainability of the tourism industry Langkawi needs to have a comprehensive and practical conservation strategy and mechanism. Without a good conservation policy the geoheritage sites are constantly under threat and under stress due to the need of space for development. To ensure the sustainability of these natural resources it is timely to include geoheritage sites in future land use planning.

The years 1870–1960 were a period of vibrant innovation in France when traditional ideas about art and living were challenged. At the turn of the twentieth century, Paris became the epicentre for creative risk, innovation and originality. The city both represented and became a ‘laboratory of culture’ that attracted individuals eager to ride the waves of modernism. What forces enabled Paris to become a site of such artistic vibrancy? What cultural labour was involved in propelling avant-gardism forwards? In this article, I introduce a few examples of women who played a vital role in the modernisation of the arts in Paris, the internationalisation of French artistic tastes, and the cultivation of Paris’s reputation as the centre of avant-gardism and artistic development. In doing so, I offer a new paradigm for understanding the art worlds of Paris in this period by revealing women as important and effective arbiters of taste.

The mountains represent territories of exceptional environmental and heritage value, holding vital resources and functions for humanity. The conservation of its geo and biodiversity is decisive, given the growth in its demand, in particular for tourism and leisure activities. In addition to their immediate physical perception, they are spaces of science and knowledge and a resource for geoeducation to promote the natural and cultural values held. The creation of geoparks constituted a new paradigm in which geosciences, territories, their heritage (material and immaterial) and the ways of life of their communities are disseminated. In this context, geoparks are based on integrated territorial approaches to the enhancement, preservation and promotion of education, biodiversity, geological heritage, tourism and scientific research, among others. Tourism, as a strategy for geoeducation and territorial valorisation, is in the mission of Estrela Geopark, promoting educational programs with initiatives for the conservation of heritage and promotion of eco-cultural resources.

AbstractGeosite and geodiversity site inventories are among the most important means of geological diversity conservation and promotion. However, there are other in situ geological features that have significant educational potential and are not included in many inventories, namely, localities of widespread rock types, common minerals and fossil-bearing strata. In this paper, a broad utilisation of these petrographic, mineralogical and palaeontological geodiversity elements for geoscience communication purposes is postulated, with a case study that focuses on the geological heritage of Poland. A simple quantitative framework for the evaluation of the educational potential of rock types is used for the assessment of preselected geological units on the geological map of Poland. The preferences of potential geotourists are estimated using the interactive web-based map. The promotional materials are written for the most distinctive rock types and geological units that scored the highest in the assessment procedure and/or were most frequently selected by users. This procedure stimulates geodiversity promotion in areas where few geosites and geodiversity sites are documented and no educational activities or interpretative facilities are available, potentially increasing the number of geotourism destinations. The rocks and minerals utilised here are exposed over large areas and can be sampled and studied by untrained collectors without any loss of geodiversity. Shifting the involvement of individuals interested in geosciences from extraordinary to more common rocky outcrops helps to protect the geological heritage and enhances conservation of the most spectacular features for future generations. Field activities such as individual searching and studying outcrops, in turn, play an important role in learning in geosciences, facilitating the acquisition of knowledge and encouraging interdisciplinary thinking. Future improvements could include expanding the applicability of the evaluation method, employment of a location-based learning approach #and more detailed studies of the preferences of potential geotourists.

Based on selected writings on women's experiences of and reflections on dress and travel published in the Hong Kong feminist journal Nuliu, this paper discusses the politics of female subjectivity in relation to the everyday. The context of the discussion is the changing actualization of the well-known feminist slogan ‘the personal is political’ within the local feminist movement in Hong Kong between the 1980s and the 1990s. The paper aims to create a new paradigm for analysing agency – the key concept in subject formation – by critiquing the ideology of choice, which is a liberal value system that connects people's imagination with the notion of personal ‘liberation’. As demonstrated by the examples of dress and travel, the everyday is a site of both possibilities and conflict for women, who generate new strategies or tactics to negotiate not only with institutions, structures and policies, but also with ‘interpellations’, ‘temporality’, ‘spatiality’, ‘performativity’, ‘symbolism’ and ‘psyche’.

ABSTRACTTwo efficient recombination systems were combined to produce a versatile method for chromosomal engineering that obviates the need to prepare double-stranded DNA (dsDNA) recombination substrates. A synthetic “targeting oligonucleotide” is incorporated into the chromosome via homologous recombination mediated by the phage Che9c RecT annealase. This oligonucleotide contains a site-specific recombination site for the directional Bxb1 integrase (Int), which allows the simultaneous integration of a “payload plasmid” that contains a cognate recombination site and a selectable marker. The targeting oligonucleotide and payload plasmid are cotransformed into a RecT- and Int-expressing strain, and drug-resistant homologous recombinants are selected in a single step. A library of reusable target-independent payload plasmids is available to generate gene knockouts, promoter replacements, or C-terminal tags. This new system is called ORBIT (for “oligonucleotide-mediatedrecombineering followed byBxb1integrasetargeting”) and is ideally suited for the creation of libraries consisting of large numbers of deletions, insertions, or fusions in a bacterial chromosome. We demonstrate the utility of this “drag and drop” strategy by the construction of insertions or deletions in over 100 genes inMycobacteriumtuberculosisandM. smegmatis.IMPORTANCEWe sought to develop a system that could increase the usefulness of oligonucleotide-mediated recombineering of bacterial chromosomes by expanding the types of modifications generated by an oligonucleotide (i.e., insertions and deletions) and by making recombinant formation a selectable event. This paper describes such a system for use inM. smegmatisandM. tuberculosis. By incorporating a single-stranded DNA (ssDNA) version of the phage Bxb1attPsite into the oligonucleotide and coelectroporating it with a nonreplicative plasmid that carries anattBsite and a drug selection marker, we show both formation of a chromosomalattPsite and integration of the plasmid in a single transformation. No target-specific dsDNA substrates are required. This system will allow investigators studying mycobacterial diseases, including tuberculosis, to easily generate multiple mutants for analysis of virulence factors, identification of new drug targets, and development of new vaccines.
