    Performative ontologies. Sociomaterial approaches to researching adult education and lifelong learning

    Full text link
    Sociomaterial approaches to researching education, such as those generated by actornetwork theory and complexity theory, have been growing in significance in recent years, both theoretically and methodologically. Such approaches are based upon a performative ontology rather than the more characteristic representational epistemology that informs much research. In this article, we outline certain aspects of sociomaterial sensibilities in researching education, and some of the uptakes on issues related to the education of adults. We further suggest some possibilities emerging for adult education and lifelong learning researchers from taking up such theories and methodologies. (DIPF/Orig.

    Deployable structures can be a good response to disaster situations, where it is necessary to provide services to a displaced population. They can be compacted into a lightweight and easily transportable package and deployed where needed providing an enclosure for use, quickly and efficiently. In this article, the possibilities of deployable structures of oblique modules are investigated, a subject little studied, but of great interest due to its many possibilities. The geometric conditions of the different modules and the typologies that can be considered are analyzed. The possibility of using the reciprocal links system developed by the authors is also studied in these meshes. Finally, the performance of a pyramidal dome that uses reciprocal linkages at the ends of its bar, is analyzed in an analytical and experimental way. Both the theoretical calculations and the experimental tests allow demonstrating the viability and effectiveness of this structural type.MINECO: BIA2016-79459-

    Developmental gene regulatory network architecture across 500 million years of echinoderm evolution

    Get PDF
    Evolutionary change in morphological features must depend on architectural reorganization of developmental gene regulatory networks (GRNs), just as true conservation of morphological features must imply retention of ancestral developmental GRN features. Key elements of the provisional GRN for embryonic endomesoderm development in the sea urchin are here compared with those operating in embryos of a distantly related echinoderm, a starfish. These animals diverged from their common ancestor 520-480 million years ago. Their endomesodermal fate maps are similar, except that sea urchins generate a skeletogenic cell lineage that produces a prominent skeleton lacking entirely in starfish larvae. A relevant set of regulatory genes was isolated from the starfish Asterina miniata, their expression patterns determined, and effects on the other genes of perturbing the expression of each were demonstrated. A three-gene feedback loop that is a fundamental feature of the sea urchin GRN for endoderm specification is found in almost identical form in the starfish: a detailed element of GRN architecture has been retained since the Cambrian Period in both echinoderm lineages. The significance of this retention is highlighted by the observation of numerous specific differences in the GRN connections as well. A regulatory gene used to drive skeletogenesis in the sea urchin is used entirely differently in the starfish, where it responds to endomesodermal inputs that do not affect it in the sea urchin embryo. Evolutionary changes in the GRNs since divergence are limited sharply to certain cis-regulatory elements, whereas others have persisted unaltered

    Using Smart Cameras to Localize Self-Assembling Modular Robots

    Get PDF
    In order to realize the goal of self assembling or self reconfiguring modular robots the constituent modules in the system need to be able to gauge their position and orientation with respect to each other. This paper describes an approach to solving this localization problem by equipping each of the modules in the ensemble with a smart camera system. The paper describes one implementation of this scheme on a modular robotic system and discusses the results of a self assembly experiment

Electronic Entry Register is a spatial planning and strategy that the South Korean government developed to control the circulation of mobile bodies as a response to the pandemic. This case study adopts an assemblage thinking to reveal how the EER came into being. It particularly highlights the data-producing human actors by adopting a posthumanist approach, to bring them forward as one of the main actors in materialising this assemblage. Examining the development processes of the EER revealed that assembling the ‘circulatory conduit’ (Deleuze & Guattari, 1997) depended largely on creating a population of docile bodies (Foucault, 2020) who were willing to, and capable of producing the right kinds of data. For this end, the South Korean government chose to simulate the national population on commercial mobile apps; which leaves the question that perhaps the task of creating a networked population is too often taken-for-granted in the discourse of smart city. Three critical dimensions in the production of digital infrastructure are proposed: the urban screens, the posthuman performances, and the leveraging effects of digital technology. The data-producing mobile bodies became the most critical actor in assembling the EER. Field research conducted at the sites of the EER across the city of Seoul, revealed that the mobile phone numbers intimately entangled to the mobile bodies (Barns, 2020) became the most critical ‘dividual’ (Deleuze, 1992) that indicated the mobile bodies. The illegibility of the QR codes and the invisibility embedded in the processing of digital data alienated the very producers; raising a sense of alienation which accompanied feelings of anxieties, doubts and powerlessness. Findings on their differentiated posthuman bodies and their sense of alienation indicated that they were anything but the homogenous ‘smart citizens’ as often imagined in the smart city discourse. Lastly, the thesis discusses the spatialities entailed in the QR codified urban space in two dimensions: spatial order embedded in the EER and spatial shifts experienced by the citizens. Spatial order embedded in the EER are discussed as ‘fragmented circulation’, ‘data-based public space’, and ‘invisible enclosure’. Spatial shifts encountered by the citizens are discussed as ‘collapsed linearity’, ‘liquid boundaries’, and ‘reproduction of digital speed’. The core element in mobilising this urban assemblage was the data-producing docile bodies moving across the urban space with the smartphones as their prostheses. As Lefebvre (2013) asserts that time-space is produced through practice, these bodies reproduced the digital speed onto the urban landscape. This case study highlights digital mediation in urban space where it emerges through the body-smartphone. It proposes that the study of digitally mediated cities, including smart city discourse, could more productively take the posthuman body a valid unit of analysis.ëłž ì—°ê”ŹëŠ” ìœ”ëĄœë‚˜19 ìœ í–‰ëł‘ì— 대한 대응 찚원에서 ìžê”Źì˜ 흐늄을 톔제하Ʞ 위핎 한ꔭ 정부가 ê”Źì¶•í•œ ‘전자출입ëȘ…부’의 형성 êłŒì •ì„ 도시 ì•„ìƒëž”ëŒìŁŒ (urban assemblage)ëĄœì„œ ì—°ê”Źí•˜ì˜€ë‹€. íŠč히 íŹìŠ€íŠžíœŽëšžë‹ˆìŠ˜ ꎀ점을 ë„ìž…í•˜ì—Ź 슀마튞폰을 볎ìČ (prosthesis)ëĄœì„œ ìČŽí™”í•˜êł  디지턞 데읎터넌 생산하는 행위자에 ìŁŒëȘ©í•˜ì˜€ë‹€. 정부가 ìš”ê”Źí•˜ëŠ” 데읎터넌 적시에 생산하는 ìžê”Źë„Œ 찜출하는 êČƒìŽ 전자출입ëȘ…부 ê°œë°œêłŒì •ì˜ í•”ì‹Źìž„ì„ 밝혔닀. 읎는 닀양한 방식의 ëŒ€ê”­ëŻŒ ì»€ëź€ë‹ˆìŒ€ìŽì…˜ì„ 톔핎 ìŽëŁšì–ŽìĄŒë‹€. 또한 정부는 Ʞ업의 ëȘšë°”음 플랫폌에 QR윔드 Ʞ늄을 íƒ‘ìžŹí•˜ì—Ź Ʞ업의 ‘옚띌읞 êł ê°â€™ì„ ꔭ가의 ‘옚띌읞 ìžê”Źâ€™ëĄœ 대ìČŽí•˜ì˜€ë‹€. 읎 êłŒì •ì€ 전 ìžê”Źê°€ 연êȰ된 ë„€íŠžì›ŒíŹ 임(ć Ž)을 í˜•ì„±í•˜êł , ìŒìƒì ìœŒëĄœ 데읎터넌 생산하êȌ 하는 êČƒìŽ 얌마나 얎렀욞 수 있는지넌 반슝하며, 슀마튞시티 ë‹ŽëĄ ì—ì„œ 옚띌읞 ìžê”Ź ê”Źì¶•ì— 대한 ëȘ…확한 전제가 믞ëč„핚을 지적하êȌ 한닀. 또한 디지턞 Ʞ반시섀의 ìŁŒìš” ê”Źì„± ìš”ì†ŒëĄœì„œ 도시 ìŠ€íŹëŠ° (urban screen), 데읎터 생산자, 레ëČ„ëŠŹì§€ íššêłŒë„Œ 제시하였닀. 읎동 쀑 슀마튞폰을 ìž‘ë™í•˜ì—Ź 지식을 생산하는 유순한 신ìČŽ (Foucault, 2020)는 전자출입ëȘ…부넌 도시 ì•„ìƒëž”ëŒìŁŒëĄœì„œ ê”Źì¶•í•˜ëŠ” í•”ì‹Ź 동렄읎 되었닀. 서욞 ì‹œëŻŒì„ ëŒ€ìƒìœŒëĄœ 한 전자출입ëȘ…부 í˜„ìž„ì—°ê”ŹëŠ” QR윔드가 읎동하는 ëȘžì„ ê°€ëŠŹí‚€ëŠ” 가임 쀑요한 ‘분ìČŽ(dividual)’ (Deleuze, 1992)ëĄœì„œ 작동핚을 확읞하였닀. 읞간의 ëˆˆìœŒëĄœ 판독 불가한 QR윔드 팚턎읎 ìƒì§•í•˜ë“Ż, 디지턞 데읎터의 ëč„시읞성은 생산, 수집, 산출, 활용의 전 êłŒì •ì—ì„œ 데읎터 생산자듀을 소왞시쌰는데, 읎는 ë¶ˆì•ˆê°êłŒ ëŹŽë „ê°ìœŒëĄœë„ 표출되었닀. ëłž ì—°ê”Źì—ì„œ ꎀ찰한 데읎터생산자듀은 슀마튞시티 ë‹ŽëĄ ì—ì„œ ‘슀마튞 ì‹œëŻŒ(smart citizen)â€™ìœŒëĄœ 표상되는 정ìč˜ì  ìŁŒìČŽë“€êłŒëŠ” ê±°ëŠŹê°€ 있었닀. ë§ˆì§€ë§‰ìœŒëĄœ, ë…ŒëŹžì€ QR윔드화된 ë„ì‹œêł”ê°„ì˜ êł”ê°„ì„±ì„ 두 가지 ìžĄë©Žì—ì„œ 녌의하였닀. 전자출입ëȘ…부에 ë‚ŽìžŹëœ êł”ê°„ì  질서에 대한 ìžĄë©ŽêłŒ, 변화된 ë„ì‹œêł”ê°„ ê”ŹìĄ°ëł€í™”ì˜ ìžĄë©ŽìŽë‹€. 전자출입ëȘ…부에 ë‚ŽìžŹëœ êł”ê°„ì  질서는 ‘파펾화된 순환 (fragmented circulation)’, ‘데읎터Ʞ반 êł”êł” êł”ê°„(data-based public space)’, ‘ëč„가시적 뎉읞성 (invisible enclosure)â€™ìœŒëĄœ 녌의하였닀. 변화된 도시 êł”ê°„ì„±ì— 대한 êČœí—˜ì€ ‘선형성의 붕ꎎ (collapsed linearity)’, â€˜ì•ĄìČŽì  êČœêł„ (liquid boundaries)’, ‘디지턞 속도의 ìžŹìƒì‚° (reproduction of digital speed)â€™ìœŒëĄœ 제시하였닀. ëłž ì—°ê”ŹëŠ” ìœ”ëĄœë‚˜19 ìœ í–‰ëł‘ì˜ 방역을 위핎 한ꔭ 정부가 ê”Źì¶•í•œ 전자출입ëȘ…부넌 디지턞 Ʞ반시섀 ìĄ°ì„±ì˜ ì‚ŹëĄ€ëĄœ ì—°ê”Źí•˜ë©°, ê·ž ê°œë°œêłŒì •ì— 있얎 디지턞 데읎터넌 생산하는 ì‹œëŻŒì„ ì°œìĄ°í•˜ëŠ” êČƒìŽ í•”ì‹ŹìŽì—ˆìŒì„ 밝혔닀. 넎페람넎(2013)가 ì‹€ìČœì„ 톔핎 ì‹œêł”ê°„ìŽ ìƒì„±ëœë‹€êł  í•˜ì˜€ë“Ż 디지턞을 ìȮ화한 신ìȮ는 디지턞 속도넌 ë„ì‹œêł”ê°„ì— ìžŹí˜„í•˜ì˜€ëŠ”ë°, ëłž ì‚ŹëĄ€ì—°ê”ŹëŠ” ìŽëŸŹí•œ ë„ì‹œêł”ê°„ì˜ ìžŹìĄ°ì§ìŽ 신ìČŽ-슀마튞폰을 톔핎 ìŽëŁšì–Žì§€ëŠ” 현상을 íŹì°©í•  수 있었닀. 읎에 따띌 ëłž ì—°ê”ŹëŠ” 디지턞 êž°êž°ë„Œ 볎ìČ ëĄœì„œ ìȮ화한 íŹìŠ€íŠžíœŽëšŒì„ ë„ì‹œêł”ê°„ ì—°ê”Źì— 있얎 유횚한 ì—°ê”Ź ë‹šìœ„ëĄœì„œ 제안하며, 디지턞 도시넌 ì—°ê”Źí•šì— 있얎 ë„ì‹œêł„íší•™ì  핚의가 적지 않음을 제시한닀.Acknowledgements i Abstract ii Chapter 1.

    Thesis (Master)--Ä°zmir Institute Of Technology, Architecture, Ä°zmir, 2011Includes bibliographical references (leaves: 112-119)Text in English; Abstract: Turkish and Englishxiii, 119 leavesThe architectural design should no longer consider just in terms of today's demands, but also the life cycle and the further requirements of the built environment. The design process should consider the adaptation to the changing conditions which can be in terms of the building usage, environmental factors or even in the changes ofsociological demands. Rapid change in activities of modern society and building technologies, has led to the need for adaptable spaces. Those spaces can be obtained by the adaptable structures which have potential for using our resources in efficient way and also for responding to the era's needs. This can be achieved with kinetic structural systems and learning adaptable structures from nature.Nature has always inspired humanity by solving the basic needs with minimum material and sustainable solutions. Observation of nature enables architects and engineers familiar with highly developed structures and lead to the creation of new forms. The designs that are produced by learning from nature lead to practical engineering solutions in terms of sustainability. The aim of this research is to propose a joint; kinetic node with multidisciplinary approach. This kinetic node is designed by inspiring from the minimum energy shape configurations and the structural orders in natural structures especially the cell membrane and analyzing the joining details of space truss structural systems and the geometric principles of Bricard linkage mechanism. This new kinetic node gives capability to construct variable static and dynamic structural systems while constructing in different structural orders

    Learning in Local Systems and Global Links: The Otigba Computer Hardware Cluster in Nigeria

    Get PDF
    Conventional wisdom suggests to the fact that poor countries are unlikely to be host to a “high-technology” sector and doing so within the organization of small and medium enterprises. This paper examines an unusual phenomenon of industrial organization in an African setting; the emergence of a cluster of an information technology hardware cluster in a very late industrializing country, Nigeria. The evolution of the Otigba Computer Hardware Village (OCV) in Lagos, Nigeria has proceeded largely without direct support from the state and indeed within a decidedly hostile institutional and arid infrastructural environment. Yet the cluster has thrived, thus far, with institutional support of a local trade and manufacturing association. The study holds important lessons for late industrializing countries entering into a knowledge intensive sector.learning, innovation system, computer hardware, clusters

    Meaningful Witnessing in the United States, India & New Zealand: The Possibility Space for Digital Video Within Human Rights, Protest Movements and Activist Practices

    Get PDF
    This dissertation examines the emergence of digital video practices rooted in human rights, social justice issues and protest movements through a number of select case studies in the United States, India and New Zealand. This project analyzes and critiques the formation of digital video practices through the lens of Manuel DeLanda’s interpretation of assemblage theory. Examining interactions between crucial elements present in a possibility space that aid in the cultivation and assembling of budding forms of digital video, this study considers the implications in the relationships between both material and expressive qualities of these assemblings. The central argument of this thesis asserts that digital video practices centered on human rights, social justice and protest movements require adaptable linkages between supportive structures, creative capacities and digital video technologies in order to produce sustainable and creative digital video practices buttressed by documentary agendas that fuel their dynamic evolution. My research seeks to engage with the complexities of agency and technology and examines their significance in different contexts by providing a constructive outlet for practitioners to share the process behind their methods in order to offer insight into their creative workflow. Digital video technologies are proliferating at a rapid pace, yet very few video practices have formed that suggest linkages to documentary traditions. One can bear witness, yet to traverse video documentation in order to create a rhetorical argument of meaningful witnessing is a complex process that requires more than easy access to mobile video tools connected to the Internet. The case studies analyzed in these three democratic nations support the argument threaded throughout the project; digital video practices have the potential to thrive, albeit in pockets where formal or informal support systems are present and through assemblages where digital video technologies are constantly being adapted and an investment in human capital is paramount to the privileging of digital video tools or online platforms. Case studies that focus on individual practices in New York City and New Zealand reinforce the difficulties practitioners face when attempting to cultivate video practices without supportive structures. Comparatively with other case studies in India and New York, individual practices with long-term organizational support navigate challenges and re-assemble their practices in order to remain sustainable and influential. This study also engages with assemblage theory in the context of documentary history and contemporary digital video practices and reassesses the historic relationship between emerging photographic, film and video tools and the lens based practitioners that harness these apparatuses for documentary purposes. Like assemblings themselves, these creative associations are never smooth at their inception, but require adaptable solutions and adjustable reassemblings in order to maintain the potential for sustainable practices to develop and flourish. This dissertation argues that as digital video practices continue to evolve, they have the potential to redefine creative approaches to documentary media and the opportunity to confront historic traditions of the documentary form

    Empowering Smallholder Farmers in Markets: Changing agricultural marketing systems and innovative responses by producer organizations

    Get PDF
    Though some producer organizations have enabled developing country farmers to exploit new opportunities and/or cope with emerging challenges through developing and/or taking advantage of innovative mechanisms and institutions, there are many farmers who lack sustainable access to inputs and services as well as to remunerative output markets. This paper is intended to generate a better understanding of the conditions which make producer organizations capable vehicles by which farmers, especially small-scale farmers in developing countries, can reach markets in a dynamic and demanding trading environment, and respond to the needs of their clients and members. It aims at identifying lessons on the forms of organizations as well as the innovative mechanisms and institutions that producer organizations can adopt and/or help promote in response to challenges in the changing agricultural marketing systems, in particular, to strengthen the bargaining position of farmers.agricultural marketing systems; producer organizations; innovative rural finance

    Programmable Assembly of DNA-Functionalized Liposomes by DNA

    This document is the Accepted Manuscript version of a Published Work that appeared in final form in ACS Nano, copyright © American Chemical Society after peer review and technical editing by publisher. To access the final edited and published work see http://dx.doi.org/10.1021/nn1030093Bionanotechnology involves the use of biomolecules to control both the structure and property of nanomaterials. One of the most studied examples is DNA-directed assembly of inorganic nanoparticles such as gold nanoparticles (AuNPs). However, systematic studies on DNA-linked soft nanoparticles, such as liposomes, are still lacking. We herein report the programmable assembly and systematic characterization of DNA-linked liposomes as a function of liposome size, charge, fluidity, composition, DNA spacer, linker DNA sequence, and salt concentration for direct comparison to DNA-directed assembly of AuNPs. Similar to the assemblies of AuNPs, sharp melting transitions were observed for liposomes where the first derivative of the melting curve full width at half-maximum (fwhm) is equal to or less than 1 °C for all of the tested liposomes, allowing sequence specific DNA detection. We found that parameters such as liposome size, charge, and fluidity have little effect on the DNA melting temperature. Cryo-TEM studies showed that programmable assemblies can be obtained and that the majority of the liposomes maintained a spherical shape in the assembled state. While liposome and AuNP systems are similar in many aspects, there are also important differences that can be explained by their respective physical properties.University of Waterloo || Natural Sciences and Engineering Research Council |
