The operculate coral Calceola gervillei Bayle, 1878 Bayle, E., 1878. Fossiles principaux des terrains de la France. Explication de la Carte Géologique de France 4(1), 1–158. [Google Scholar] is described for the first time on the basis of the type material from the Cotentin region of Normandy (North Armorican Domain), from Early Devonian (likely upper Lochkovian to lower Pragian) strata, and is chosen as the type species of the monotypic new genus Gerviphyllum. The new genus is also present in the l’Armorique Formation (lower Pragian) of the Plougastel Peninsula (Central Armorican Domain) as Gerviphyllum sp. cf. G. gervillei. One locality in the upper Emsian (Polygnathus serotinus Conodont Zone) Le Fret Formation, on the northern coast of the Crozon Peninsula, has yielded operculate coral specimens described here as ?Chakeola sp., the first (tentative) record of the genus outside eastern Australia, south China and Vietnam. The operculate coral Calceola collini sp. nov. is described from six localities in the early Middle Devonian (Eifelian: Polygnathus costatus Conodont Zone) Saint-Fiacre Formation of the Plougastel and Crozon Peninsulas (Central Armorican Domain), despite the fact that knowledge of the internal characters, especially of the operculum, of the type species Calceola sandalina is very limited. From an extensive review of published references to Calceola from France, we conclude that only the record of Collin (1929 Collin, L., 1929. Un nouveau gisement à calcéoles dans le Dévonien de la Presqu’île de Crozon (Finistère). Bulletin de la Société Géologique et Minéralogique de Bretagne 7(3/4), 201–208. [Google Scholar]) is valid.

New visual methods for teaching intersectionality from a spatial perspective in a geography and gender course

Intersectionality is a complex concept to deal with when doing research but also when teaching the interrelationships between space and social relations. Here we present “Relief Maps” as a visual tool for teaching intersectionality and its spatial dimension in higher education courses. “Relief Maps” are a model developed for research and applied in a Geography and Gender course at the Universitat Autònoma de Barcelona (UAB) with the aim of promoting student reflection on the relationships between power structures, places and lived experiences, starting from their everyday lives.     

The Current Status of the Kenya Capsian

East Africa is home to a rich array of stone-tool traditions that span human prehistory. It is unsurprising, therefore, that the region attracted pioneer prehistorians in the early twentieth century, including L. S. B. Leakey, E. J. Wayland and T. P. O’Brien, who created the first cultural framework for East African prehistory during the 1930s. Although aspects of this framework remain relevant today, others have become misunderstood relics of an old classification system that hinders current research. This is particularly evident in the classification of a Later Stone Age (LSA) culture – the Kenya (East African) Aurignacian, later known as Kenya (East African) Capsian. Although this cultural entity was redressed during the 1970s and 1980s and redefined as the Eburran industry, there is still mystique surrounding the current status of the Kenya Capsian, its original scope and definition, the relationship with the Eburran and its position within a modern understanding of the East African LSA. This is largely due to paradigmatic shifts in researcher attitudes, leading to the use of the Eburran as a false proxy. It is necessary now to completely remove the term Kenya Capsian as an indication of similarity among the different LSA technologies. However, there also needs to be less emphasis on the importance of the Eburran and recognition that it is just one example of a multitude of diverse localised LSA industries. This will open the way for future research into the LSA and facilitate our greater understanding of recent prehistory in East Africa.     

The future role of GIS education in creating critical spatial thinkers

Teaching of critical spatial thinking in higher education empowers graduates to effectively engage with spatial data. Geographic information systems (GIS) and science are taught to undergraduates across many disciplines; we evaluate how this contributes to critical spatial thinking. The discipline of GIS covers the whole process of spatial decision-making, but GIS modules often ignore the context setting of spatial problems, and just cover the technical aspects of how to use GIS software. We outline how some existing GIS practicals could be improved to focus on the development of critical spatial thinking skills, competences and abilities that are valuable to graduates.     

Re-evaluating the Neolithic: The Impact and the Consolidation of Farming Practices in the Cantabrian Region (Northern Spain)

Research projects undertaken in the Cantabrian region since 1980 have produced new, high-quality information about the neolithisation process(es) in this area. It is now necessary to review this archaeological information and test the main hypotheses put forward to explain it. This paper presents an update on the archaeological evidence (sites, chronological dates, archaeozoological, archaeobotanical and technological information) for the early Neolithic in the Cantabrian region. It summarizes recent research on neolithisation in the region, and assesses the impact of this process during the early Neolithic, and its later consolidation. Although the available information is still incomplete, it is now possible to identify the focal point of the introduction of elements characteristic of the Neolithic way of life in the region. Current evidence suggests that it is in the eastern sector, where the earliest arrival of domesticates and new technologies such as pottery has been attested. The existence of continuities—such as sustained reliance on hunting and gathering and the coexistence of old and new funerary rites—suggests the persistence of native populations, which gradually participated in the neolithisation process after an ‘availability phase’.     

La virtud sospechosa: Teresa de Jesús y su condición femenina

ABSTRACT

Teresa de Jesús (1515–1582) lives in a patriarchal society opposed to the intellectual and spiritual development of women, something that she will not only not accept but also fight against, claiming a series of rights (the right to life, to expression, to autonomy, to the free development of her abilities, to have an active role in the Church, to relate to God through prayer, etc.) in spite of the restrictions of censorship and the cloud of suspicion that hung over her for being a mystic, the founder of convents, and the daughter and granddaughter of a converso. Furthermore, Teresa, with her reforms, would present an alternative life for women, as her convents would be spaces for freedom and women's solidarity.     

Context and the role of policies to attract foreign R&D in Europe

This paper explores the effectiveness of policies ‘in’ attracting the foreign research and development (R&D) of multinational enterprises (MNEs) to specific countries in Europe. We develop a macroeconomic investigation covering 29 European countries during the period between 1990 and 2012 in order to address: (a) whether the provision of direct financial support for business R&D is effective for the attraction of foreign R&D; (b) whether direct support is more effective than indirect support for this purpose and (c) whether the link between direct financial support for business R&D and the foreign R&D of MNEs is conditioned by the context within which the support is provided. The results of the analysis show that, first, the provision of direct financial support is generally effective for the attraction of foreign R&D by MNEs. Second, direct support for business R&D is more effective for this purpose than indirect support. Third, the provision of direct financial support for business R&D yields greater returns in contexts that are more socio-economically suitable for knowledge-intensive, innovative activity.     

A gender analysis of everyday mobility in urban and rural territories: from challenges to sustainability

Gender differences in mobility patterns between women and men have long been acknowledged. This study analyses how these differences are reproduced in different urban and rural contexts. Using mobility data from a large travel survey taken in 2006 in Spain, we examine the differences between gender mobility through age, modal split and trip purposes. Special attention is paid to how territory shapes mobility and how these territorial settings differently affect gendered mobilities. The use of this data source allows the comparison of all trips made by the total population, including all means of transport. By taking a global view on mobility, the uneven relationships that men and women have with different means of transport become more visible. After disaggregating data by age and territorial settings, results show that women are using sustainable transport modes more often than men, and travelling for more diverse reasons. Gender is thus a fundamental variable in understanding modal split and, by extension, transport sustainability, in terms of energy consumption and the emission of greenhouse gases. From this point of view, we consider women's mobility knowledge and practices – typically related to the most sustainable means of transport – as factors with rising value that could effectively guide public policy in its way to promote more sustainable mobility patterns.     

Decolonizing travesti space in Buenos Aires: race,sexuality, and sideways relationality

Scholars of space usually neglect the history of travesti populations in Latin America. It is misrepresented not only by disciplinary blind spots but also by global narratives concerned with rehabilitating queer subjects within homonormative projects. Analyzing neoliberal narratives that delink conflicts about racialization and sexuality in Argentina, this article makes room to decolonize the study of travesti experience and embodiment in Buenos Aires's red zone. It examines a network of racialized travestis and their spatial practices, including their migration from the Andean northwest to the sex-work circuits of Buenos Aires. Finally, this article introduces the notion of sideways relationality to account for the cultural and spatial labor that racialized travestis perform at the oppositional margins of homonormative reflexivity.
