Teaching geography for a sustainable world: a case study of a secondary school in Spain

Geography has a major responsibility in delivering education for sustainable development (ESD), especially because the geographical concepts of place and space are key dimensions for the analysis and pursuit of sustainability. This paper presents the results of a research that investigated how the teaching of geography in secondary education in Catalonia (Spain) contributes to ESD. For the development of this research it was explored what is involved in understanding and resolving issues about sustainable development and how geography teachers might best conceptualize and teach in this new domain. As a result of this theoretical reflection it has been defined a proposal or model for reorienting the geography curriculum from the basis of the ESD paradigm, which is based and structured in four groups of criteria and recommendations as follows: recommendations for defining competences and learning objectives; criteria for selecting geographical contents and themes; criteria for selecting geographical areas and for the use of scale; and finally, recommendations for choosing the most suitable teaching and learning approach

5G-crosshaul: an SDN/NFV integrated fronthaul/backhaul transport network architecture

This article proposes an innovative architecture design for a 5G transport solution (dubbed 5G-Crosshaul) targeting the integration of existing and new fronthaul and backhaul technologies and interfaces. At the heart of the proposed design lie an SDN/NFV-based management and orchestration entity (XCI), and an Ethernet-based packet forwarding entity (XFE) supporting various fronthaul and backhaul traffic QoS profiles. The XCI lever-ages widespread architectural frameworks for NFV (ETSI NFV) and SDN (Open Daylight and ONOS). It opens the 5G transport network as a service for innovative network applications on top (e.g., multi-tenancy, resource management), provisioning the required network and IT resources in a flexible, cost-effective, and abstract manner. The proposed design supports the concept of network slicing pushed by the industry for realizing a truly flexible, sharable, and cost-effective future 5G system.This work has been funded by the EU H2020 project “5G- Crosshaul: The 5G Integrated Fronthaul/Backhaul” (Grant no. 671598)

Using ICT to contact the target culture: teachers’ view

While information and communication technologies (ICT) have made speakers of and content from the target foreign culture easily accessible to learners and teachers alike, they may cause conditions for FL teachers. This study sought to uncover the nature and extent of FL teachers' use of ICT to contact the target culture, both for instruction and teachers’ informal lifelong learning. By means of a survey, interviews and a mini-group interview with students, we portrayed the FL teachers' knowledge, beliefs, context, and behaviour in terms of ICT, and scrutinized how they are related. Findings showed that while teachers and students are sufficiently ICT-skilled and equipped, informal exchanges on the Internet are the exception. Excerpts from the interviews are presented in association with quantitative results

Freedom and the Internet: empowering citizens and addressing the transparency gap in search engines

This work contemplates the limits and possibilities of exercising the right to freedom through the use of the Internet. Freedom can be defined as the preservation of the right of autonomy in the daily life of citizens or members of social and political organisations, whilst respecting the utilisation of this right, by oneself, or by one or more persons or citizens. A number of strengths and weaknesses are identified in this regard. The paper examines the way in which search engines like Google exemplify restrictions on freedom: they are enhanced by the use of technical resources that are aimed at the most efficient exploitation of the information available on the Internet; the resources are not utilised to reinforce the rights of the users. Finally, it is argued that the limits imposed on freedom can be overcome with the aid of technical tools such as thesauri that can produce a positive relationship between freedom and Internet

From Chávez to Maduro: Continuity and Change in Venezuelan Foreign Policy

This article addresses the transition from the presidency of Hugo Chávez to that of Nicolás Maduro, in the light of the effects of the dynamics in domestic politics and the changing international order on the formulation of Venezuela's foreign policy. We start from a central question: how does Maduro's government, amid a less favourable global scenario, face the international commitments made by its predecessor under complex and different domestic conditions? Our central hypothesis is that the historical currents of sociopolitical fragmentation, regional tensions and the energy market, pose difficulties to the continuation of an expansive foreign policy, but in turn act as a stimulus for greater centralisation of power internally, and the politicisation of the foreign policy agenda, in line with the objectives and general trends pursued by the governing party

Words around Information Literacy: Construction and use of concepts to support scholarship as conversation

Inspired by Scholarship as Conversation, a frame from the conceptual ACRL Framework (ACRL, 2016), this study aims to reflect on Information Literacy concepts, expressed in a specific terminology, that the discipline, particularly in higher education, has been adding, contributing to the construction of this scientific area and dialogue in academy and profession. The work seeks to demonstrate how concepts of information literacy in higher education has evolved in parallel with the publication of theoretical frameworks, defined from guiding documents. This vision aims to clear knowledge of the discourse produced on information literacy, showing trends, and investigative clues. Terminology produced in Information Literacy strengthens the affirmation of the disciplinary field, benefiting the scientific community through a more assertive and understandable dialogue between researchers.N/

Pleading and the Dilemmas of “General Rules”

This article comments on Professor Geoffrey Miller’s article about pleading under Tellabs and goes on (1) to use Tellabs, Bell Atlantic Corp. v Twombly, and Iqbal v. Hasty (in which the Court has granted review) to illustrate the limits of, and costs created by, certain foundational assumptions and operating principles that are associated with the Rules Enabling Act’s requirement of “general rules,” and (2) more generally, to illustrate the costs of the complex procedural system that we have created. Thus, for instance, the argument that the standards emerging from Twombly should be confined to antitrust conspiracy cases confronts the foundational assumptions that the Federal Rules are trans-substantive and that they cannot be amended by judicial interpretation. Similarly, in Iqbal, the Government presumably denies that it is calling for the imposition of a heightened fact pleading requirement in cases involving high government officials entitled to an immunity defense because the Court seems to have made it impossible for the judiciary openly to impose such a requirement other than through “The Enabling Act Process.” The Court may, however, take a different view of the appropriate contextual plausibility judgment than did the lower court in Iqbal. If so, however, the Court would thereby confirm the view that Twombly is an invitation to the lower courts to make ad hoc decisions reflecting buried policy choices. I therefore argue that, if the Court is persuaded that the changes already made to pleading jurisprudence are insufficient to accommodate the needs of the immunity defense, it should forthrightly require fact pleading as a matter of substantive federal common law
