    N° ISBN - 978-2-7380-1284-5International audienceLearning is essential for local innovation and enhancing the ability of the rural clients to discover new solutions to prevailing challenges. Equally, the growing complexities of the challenges in the theatre of agriculture and rural development require multi-actor learning process. Participatory communication through face-to-face interaction remains an important approach to support local people's innovation capacity. Is there any mean other than face-to-face interaction that enables learning for innovations? Video has been used for several decades, however, in most cases instrumentally as a mass media for expert information dissemination. In recent years the interest in the alternative use of video, mostly known as participatory video, has grown. This study attempts to understand the potential of participatory video to support learning for local innovation by reviewing available literature about the cases of participatory video in the field of agriculture and natural resource management. A deductive coding approach was employed in order to identify the potentials of participatory video. The documented cases we found in the literature suggest that participatory video has a substantial role for both vertical and horizontal flow of local knowledge and information in a multi-actor setting. It creates a ‘safe space' for communication where different actors are able to articulate their perceptions. What follows, actors get an opportunity for reciprocal learning process. Participatory video facilitates communication for the marginalized segment of developing nations in Asia and Africa to represent their knowledge and skills and to link these to other knowledge bodies such as scientific, formal, managerial and bureaucratic. Participatory video stimulates reflection and experimentation by creating new impetus for learning within and across stakeholder (actor) groups. Nevertheless, potentials of participatory video depend on careful analysis of social competencies of facilitators, institutional ambience and role of intermediaries and facilitating organizations. We also proposed future research angles on these issues

    Semantics-based analysis of content security policy deployment

    Get PDF
    Content Security Policy (CSP) is a recentW3C standard introduced to prevent and mitigate the impact of content injection vulnerabilities on websites. In this article, we introduce a formal semantics for the latest stable version of the standard, CSP Level 2. We then perform a systematic, large-scale analysis of the effectiveness of the current CSP deployment, using the formal semantics to substantiate our methodology and to assess the impact of the detected issues. We focus on four key aspects that affect the effectiveness of CSP: browser support,website adoption, correct configuration, and constant maintenance. Our analysis shows that browser support for CSP is largely satisfactory, with the exception of a few notable issues. However, there are several shortcomings relative to the other three aspects. CSP appears to have a rather limited deployment as yet and, more crucially, existing policies exhibit a number of weaknesses and misconfiguration errors. Moreover, content security policies are not regularly updated to ban insecure practices and remove unintended security violations. We argue that many of these problems can be fixed by better exploiting the monitoring facilities of CSP, while other issues deserve additional research, being more rooted into the CSP design

    Queer feminine disidentificatory orientations: occupying liminal spaces of queer fem(me)inine (un)belonging

    Get PDF
    This thesis develops fresh critical insights regarding dynamics of queer feminine identity construction and community (un)belonging, with a specific focus on the rhetorics and realities of inclusion and exclusion occurring within queer feminine identities, communities and representations. The project takes a intersectional approach to exploring these dynamics by interrogating how various positionalities (e.g. “race”, disability, class etc.) interact with queer feminine genders and sexualities. Synthesising insights from Sara Ahmed’s (2006) queer phenomenology regarding processes of orientation with JosĂ© Esteban Muñoz’s (1999) theory of disidentifications, the project explores the possibilities that experiences and articulations of queer feminine disidentificatory orientations offer for a critical take on queer femininities from within. The key research question that this project addresses is: How and why are disidentificatory orientations experienced by various differently positioned queer feminine subjects and what can queer feminine disidentificatory orientations tell us about dynamics of inclusion, exclusion and (un)belonging within queer feminine subjectivities, communities and representations? The project developed a collaborative queer fem(me)inist ethnographic approach that combined questionnaires, interviews and visual materials (collages and photographs) produced by a diverse sample of 15 queer feminine participants in the UK, with insights gained from a discursive analysis of three major contemporary femme anthologies: ChloĂ« Brushwood Rose and Anna Camilleri’s (2002) Brazen Femme, Ulrika Dahl and Del LaGrace Volcano’s (2008) Femmes of Power and Jennifer Clare Burke’s (2009) Visible. The project presents a significant new data set which demonstrates the complexities, politics and cultures of femme subjectivities and the ranges of (sub)cultural capitals that one has to either already be invested in, or actively invest in, to access queer feminine identities, recognition and community belonging. Thus, the project argues for the continued necessity of engaging in positioned reflexive work on the lived experiences of minority subjects within our own queer, feminist and femme communities

    Computational Resource Abuse in Web Applications

    Get PDF
    Internet browsers include Application Programming Interfaces (APIs) to support Web applications that require complex functionality, e.g., to let end users watch videos, make phone calls, and play video games. Meanwhile, many Web applications employ the browser APIs to rely on the user's hardware to execute intensive computation, access the Graphics Processing Unit (GPU), use persistent storage, and establish network connections. However, providing access to the system's computational resources, i.e., processing, storage, and networking, through the browser creates an opportunity for attackers to abuse resources. Principally, the problem occurs when an attacker compromises a Web site and includes malicious code to abuse its visitor's computational resources. For example, an attacker can abuse the user's system networking capabilities to perform a Denial of Service (DoS) attack against third parties. What is more, computational resource abuse has not received widespread attention from the Web security community because most of the current specifications are focused on content and session properties such as isolation, confidentiality, and integrity. Our primary goal is to study computational resource abuse and to advance the state of the art by providing a general attacker model, multiple case studies, a thorough analysis of available security mechanisms, and a new detection mechanism. To this end, we implemented and evaluated three scenarios where attackers use multiple browser APIs to abuse networking, local storage, and computation. Further, depending on the scenario, an attacker can use browsers to perform Denial of Service against third-party Web sites, create a network of browsers to store and distribute arbitrary data, or use browsers to establish anonymous connections similarly to The Onion Router (Tor). Our analysis also includes a real-life resource abuse case found in the wild, i.e., CryptoJacking, where thousands of Web sites forced their visitors to perform crypto-currency mining without their consent. In the general case, attacks presented in this thesis share the attacker model and two key characteristics: 1) the browser's end user remains oblivious to the attack, and 2) an attacker has to invest little resources in comparison to the resources he obtains. In addition to the attack's analysis, we present how existing, and upcoming, security enforcement mechanisms from Web security can hinder an attacker and their drawbacks. Moreover, we propose a novel detection approach based on browser API usage patterns. Finally, we evaluate the accuracy of our detection model, after training it with the real-life crypto-mining scenario, through a large scale analysis of the most popular Web sites

    'Thinking-through-Complicity' with Te Iwi o Ngāti Hauiti: Towards a Critical Use of Participatory Video for Research

    Get PDF
    This thesis explores some of the seductions and dangers of participatory video for research (PVR) involving Indigenous Māori and Pākehā research partners. The project within which PVR was used focused on exploring relationships between place, identity and social cohesion within ‘remote’ rural communities. It involved about 15 members of the Potaka whānau of Te Iwi o Ngāti Hauiti in the central Rangitīkei district of the North Island, Aotearoa New Zealand. A small group of iwi members, myself and an audiovisual specialist and trainer negotiated the project’s focus, process and ethics during 1998. A different group of iwi members were then trained in video production and community research methods later that year and supported to produce their own productions, and carry out video research interviews with other iwi members. The entire process of negotiation, training and collaborative research was filmed for archival and research purposes with everyone’s consent, and several collaborative publications and presentations have been produced since 1999. The discursive space opened up by Ngāti Hauiti’s engagement with, and use of, video provides an opportunity to attend to the ‘cultural mediations’ that occurred throughout the research partnership and to inquire into the possible ‘empire building effects’ of visual technologies within participatory research more generally. The focus on PVR within a Māori context also prompts questions about the visual’s transformative potential within geographic research, and the implications of working through the use of a visual medium for rethinking disciplinary practices and knowledges, particularly when working cross-culturally. In the thesis, I first review the evolution and attendant challenges associated with both the use of participation and video within research contexts. I trace their similar origins in modernist attempts to ‘know’ and ‘empower’ marginalised others, and highlight the ongoing marginalisation of Indigenous perspectives within mainstream debates. I then engage with conceptualisations of complicity and develop an analytical framework that expands on current discursive and ideological discussions to also attend to its material, embodied and spatial dimensions. Using this framework and a complementary autoethnographic and ‘hyper-self-reflexive’ approach, I track aspects of my own power, complicity and desire within my research practice in the PVR project during the period 1998-2001. This approach involves the development of a particular reading position to focus on critical incidents of my research practice and a means of grappling productively with the polyvalent nature of my audiovisual and other information sources. I discuss these critical incidents within three processes associated with the research: facilitation, production and reception, attending to the complex and multifaceted interplay of audiovisual texts, their producers and their audiences throughout. Such a thesis is expedient given that powerful and often uncritical rhetoric that besets participatory research and development is fast taking hold within geography. It is also timely given the proliferation of affordable and accessible audiovisual technology and its increasing use within geography and other social sciences. As geographers respond to calls to embrace more visual, tactile and other methods, this thesis offers possibilities for the repoliticisation of participatory discourse within social geography, through a more considered engagement with participatory action research, Indigenous research practices and audiovisual media such as video. I offer cautionary insights into the ‘power-full’ effects of these ways of working

    New Germans, new Dutch: literary interventions

    In the globalised world of today, traditional definitions of national Self and national Other no longer hold. The unmistakable transformation of German and Dutch societies demands a thorough rethinking of national boundaries on several levels. This book examines how literature of migration intervenes in public discourses on multiculturality in Germany and the Netherlands, epitomised in the strikingly parallel debates on the 'German Leitkultur' and the Dutch 'multicultural drama' in the year 2000. By juxtaposing detailed analyses of literary work by the Turkish-German writers Emine Sevgi özdamar and Feridun Zaimoglu and the Moroccan-Dutch writers Abdelkader Benali and Hafid Bouazza, New Germans, New Dutch offers crucial insights into the specific ways in which this literature negotiates its national context of writing. This book demonstrates how German literature of migration seeks alternative forms of community outside the national parameters, whereas the Dutch literature negotiates difference and re-imagines Dutchness within the national framework.De etnische transformatie van de Duitse en Nederlandse samenleving vraagt om diepgaande reflectie op het omstreden concept van nationale identiteit. Literatuur levert een belangrijke bijdrage aan dit proces van reflectie. New Germans, New Dutch onderzoekt migratieliteratuur in de Nederlandse en Duitse context. Literaire werken van de Turks Duitse schrijvers Emine Sevgi özdamar en Feridun Zaimoglu en de Marokkaans-Nederlandse schrijvers Abdelkader Benali en Hafid Bouazza worden beschouwd als kritische buiteninterventies in polariserende debatten over het 'multiculturele drama' en de 'deutsche Leitkultur'. De Duits-Nederlandse vergelijking biedt een verrassend inzicht in de nationale specificiteit van zowel deze interventies als van de verbeeldingen van nationale identiteit in deze literatuur.
