Biochar standardization and legislation harmonization

It is a relatively new concept to use biochar as soil amendment and for climate change mitigation. For this reason, the national and supranational legislation in the EU is not yet adequately prepared to regulate both the production and the application of biochar. Driven by this “regulatory gap”, voluntary biochar quality standards have been formed in Europe with the European Biochar Certificate, in the UK with the Biochar Quality Mandate and in the USA with the IBI Standard which is intended to be used internationally. In parallel to this, biochar producers and biochar users in a number of EU countries were partly successful in fitting the new biochar product into the existing national legislation for fertilisers, soil improvers and composts. The intended revision of the EC Regulation 2003/2003 on fertilisers offers the opportunity to regulate the use of biochar at the EU level. This publication summarizes the efforts on biochar standardization which have been carried out by voluntary products standards and illustrates existing legislation in EU member states, which apply to the production and use of biochar. It describes existing and planned EU regulations, which impact biochar applications and it develops recommendations on the harmonization of biochar legislation in the EU.  First published online: 24 Jan 201

Festival and the City: Performativity of Sexual acts in public spheres

In this paper, we address the perception of sexual activities in public spaces and how they become aesthetic, social and cultural intervention once expressed through and embodied within performative events (theatre, street performance, carnival, festival, rave etc). A substantial amount of research has been done on the relation between sexuality and gender about public spaces, and influence of civic and urban identity on public expression of sexuality and gender. We will look at the invented rituals establishing sexuality within a context of performativity through relationships with public spaces. As the case studies, we will use the works of theatre companies La Fura dels Baus and Teatro Oficina. To set up the set of relationships between inside and outside, we will borrow a useful concept on ‘spheres' from the German philosopher Peter Sloterdijk to look at the public space as a system of spheres where a different set of rules apply enabling actions to take place. These performances in urban contexts, as well as some festivals and particularly carnivals, become a way of the staging of sexual acts in public space, in opposition to the dominant narrative of private – domestic space. We will look at how collectiveness and civic spaces become essential elements of this phenomenon and its relevance in our contemporary reality as an element of subversion of social structures. We will also examine performative events where sexual acts as a language of human relationship in public spaces bringing intimacy

Performing the Digital Self: Understanding Location-Based Social Networking, Territory, Space, and Identity in the City

Expressions of territoriality have been positioned as one of the main reasons users alter their behaviors and perceptions of spatiality and sociality while engaging with location-based social networks (LBSN). Despite the potential for this interplay to further our understanding of LBSN usage in the context of identity, very little work has actually been done towards this. Addressing this gap in the literature is one the chief aims of the article. Drawing on an original six-week study with 42 participants utilizing a bespoke LBSN entitled ‘GeoMoments’, our research explores: (1) the way that territoriality is linked to self-identity; and (2) how this interplay affects the interactions between users as well as the environments they inhabit. Our findings suggest that participants affirmed their self-identity by selectively posting and claiming ownership of their neighborhood through the LBSN. Here, the locative decisions made related to risk, hierarchies, and the users’ relationship to the area. This practice then led participants to discover and interact with the digital information overlaying their physical environments in a playful manner. These interactions demonstrate the perceived power structures that are facilitated by identity claims over a virtual area. In the main, our results reaffirm that territoriality is a central concept in understanding LBSN use, while also drawing attention to the temporality involved in user-to-user and user-to-place interactions pertaining to physical place mediated by LBSN

Transcultural engagement with Polish memory of the Holocaust while watching Leszek Wosiewicz's Kornblumenblau

Kornblumenblau (Leszek Wosiewicz 1989) is a film that explores the experience of a Polish political prisoner interned at Auschwitz I. It particularly foregrounds issues related to Polish-Jewish relations during the Holocaust in its diegesis. Holocaust films are often discussed in relation to representation and the cultural specificity of their production context. However, this paper suggests thinking about film and topographies, the theme of this issue, not in relation to where a work is produced but in regards to the spectatorial space. It adopts a phenomenological approach to consider how, despite Kornblumenblau's particularly Polish themes, it might address the transcultural spectator and draw attention to the broader difficulties one faces when attempting to remember the Holocaust. Influenced particularly by the writing of Jennifer M. Barker and Laura U. Marks, this paper suggests that film possesses a body ¬¬- a display of intentionality, beyond those presented within the diegesis, which engages in dialogue with the spectator. During the experience of viewing Kornblumenblau, this filmic corporeality draws attention to the difficulties of confronting the Holocaust in particularly haptic ways, as the film points to the unreliability of visual historical sources, relates abject sensations to concentrationary spaces and breaks down as it confronts the scene of the gas chamber

Transformative sensemaking: Development in Whose Image? Keyan Tomaselli and the semiotics of visual representation

The defining and distinguishing feature of homo sapiens is its ability to make sense of the world, i.e. to use its intellect to understand and change both itself and the world of which it is an integral part. It is against this backdrop that this essay reviews Tomaselli's 1996 text, Appropriating Images: The Semiotics of Visual Representation/ by summarizing his key perspectives, clarifying his major operational concepts and citing particular portions from his work in support of specific perspectives on sense-making. Subsequently, this essay employs his techniques of sense-making to interrogate the notion of "development". This exercise examines and confirms two interrelated hypotheses: first, a semiotic analysis of the privileged notion of "development" demonstrates its metaphysical/ ideological, and thus limiting, nature especially vis-a-vis the marginalized, excluded, and the collective other, the so-called Developing Countries. Second, the interrogative nature of semiotics allows for an alternative reading and application of human potential or skills in the quest of a more humane social and global order, highlighting thereby the transformative implications of a reflexive epistemology.Web of Scienc

Schools and skills of critical thinking for urban design

© 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group. This paper explores possible ways in which urban design can engage with critical thinking and critical theory. After a brief explanation of the terms, with particular attention to the Frankfurt School of thought, it provides various answers to the question as to whether urban design is critical or not. One categorization applied to planning critical theory is then used to explain the potential for employing critical theories in urban design. Critical thinking skills are then argued to be helpful for enriching the literature of urban design in order to achieve better practice. The conclusion is that urban design can benefit from critical creativity, which is an embodiment of critical thinking within the limits imposed onto creativity. In this paper, the ways in which urban design can engage with both critical theory and with critical thinking are explored in order to achieve better critical creativity in the field
