Sustainability transitions are dependent on the development and diffusion of transformative skills and competencies. However, the prevailing notion that learning for sustainability transitions will be led by universities, technical colleges and other similar institutions is practically not feasible in much of the global south. Net-Map is a social network analysis tool that uses interviews and mapping to help people understand, visualise, discuss, and improve situations in which many different actors influence outcomes (Schiffer & Hauck, 2010). In response to the pressing need for new approaches to the development and diffusion of sustainability skills, this paper evaluates Net-Map’s suitability as a methodological tool for educators, knowledge brokers and students seeking to enhance the navigability of the often complex and uncharted occupational pathways they encounter. To do this, the research applied Net-Map to an emerging sustainability niche within the food system in order to map the learning pathways of successful sustainability pioneers. We found that Net-Map was helpful in identifying diffuse informal knowledge networks and teaching resources. Being free, quick to learn and easy to use, Net-Map is a potentially low-cost method for circumventing traditionally costly approaches to curriculum development and accreditation – assisting community-based actors to make sense of the informal knowledge and competency networks that support emerging career fields. In emerging career fields such as organic farming, where pioneer knowledge is fragmented, poorly documented and often disregarded by mainstream-science, Net-Map could be useful in the preparatory phase of curriculum planning and design, providing training designers, course conveners and facilitators with contextually informed insights.

Resumo: O Ensino de Química no Brasil nos dias atuais segue, predominantemente, um modelo tradicional, sendo verificada a utilização de metodologias pedagógicas repetitivas de baixo potencial de aprendizagem. Nesse contexto o presente trabalho teve por intuito elaborar um plano de aula diferenciado que envolvesse conteúdos químicos, dados históricos e discussões filosóficas a partir do tema “Ares”, utilizando a demonstração investigativa como recurso didático para propiciar uma maior motivação e envolvimento dos discentes. Para se alcançar o objetivo proposto, foi realizado um conjunto de quatro experimentos, utilizando materiais de baixo custo e fácil aquisição, a saber: Peso do flogisto; Síntese do Ar Fixo (CO2); Síntese do Ar Inflamável (H2); Síntese do Ar Desflogisticado (O2). A análise qualitativa dos dados obtidos demonstrou que o formato de aula utilizado é aplicável ao Ensino Médio, tornando a aula mais dinâmica, sendo, portanto, apreciada pela maior parte dos discentes, o que possibilitou uma maior motivação desses.Palavras-chave: Experimentação Demonstrativa; História da Química; Recursos no Ensino de Química. The history of chemistry through the “airs”: an experimental contribution to chemistry teachingAbstract: The Chemistry teaching in Brazil nowadays follows, predominantly, a traditional model, being verified the use of repetitive pedagogical methodologies with low learning potential. In this context, the present work aimed to elaborate a different lesson plan involving chemical contents, historical data and philosophical discussions based on the theme “Airs”, using investigative demonstration as a didactic resource to provide more motivation and involvement of students. To achieve the proposed goal, a set of four experiments was carried out, using low-cost and easy-to-acquire materials, namely: Weight of phlogiston; Synthesis of Fixed Air (CO2); Flammable Air Synthesis (H2); Synthesis of Dephlogisticated Air (O2). The qualitative analysis of the data obtained showed that the class format used is applicable to high school, making the class more dynamic, being, therefore, appreciated by most of the students, which enabling a greater motivation.Keywords: Demonstrative Experimentation; History of Chemistry; Chemistry Teaching Resources.

Sustainable Food System

When urban agriculture becomes a sustainability initiative with institutional backing, it can drive green gentrification even when its advocates are well intentioned and concerned about the possible exclusion of urban farmers and residents. This chapter explores these tensions through the notion of an urban agriculture fix, which I apply to a case in Denver, Colorado. Urban farmers accessed land more easily after the Great Recession and as a result were a force for displacement and at risk of displacement as the city adopted sustainable food system plans, the housing market recovered, and green gentrification spread. This case suggests the importance of explaining how political economy and culture combine to drive neighborhood disinvestment and economic marginalization, which can compel the entrance of urban agriculture due to its perceived low cost and potential high return for local residents. Yet, while urban agriculture may provide some short-term benefits, it may ultimately be entangled in some of the long-term harms of green gentrification.

The need to rationalise teaching resources underpinned a project at Monash University that used a Delphi technique to re-examine the teaching curriculum of two key topic areas in the medical curriculum – ophthalmology and dermatology – from an undergraduate, graduate and vocational perspective. Using Bloom’s taxonomy the learning objectives from these topic areas were collated and analysed. This process allowed the revising and redistributing of learning objectives of the curricula to reduce the likelihood of duplication of teaching or more importantly gaps in teaching occurring. This process highlighted the potential utility of using a transgenerational approach to curriculum planning but the outcomes are limited due to the small number of participating educators and the lack of formal evaluation of the method.

Practical Applications

Recently, the Field Programmable Gate Array (FPGA) technology offers the potential of designing high performance systems at low cost. The discrete wavelet transform has gained the reputation of being a very effective signal analysis tool for many practical applications. However, due to its computation-intensive nature, current implementation of the transform falls short of meeting real-time processing requirements of most application. The objectives of this paper are implement the Haar and Daubechies wavelets using FPGA technology. In addition, the comparison between the Haar and Daubechies wavelets is investigated. The Bit Error Rat (BER) between the input audio signal and the reconstructed output signal for each wavelet is calculated. It is seen that the BER using Daubechies wavelet techniques is less than Haar wavelet. The design procedure has been explained and designed using the stat-of-art Electronic Design Automation (EDA) tools for system design on FPGA. Simulation, synthesis and implementation on the FPGA target technology has been carried out.

Theories Of Change

The commonly used words ‘transformation’ and ‘transition’ tend to lose their edge when used for any significant change process as is rather often the case. Partners and wider stakeholders in initiatives related to ‘sustainability transitions’ therefore often entertain different perspectives on what the strategic orientation of an initiative is or is meant to be. Common planning and design processes such as situation analysis and theories of change, however, often do not sufficiently cater to this dynamic. As a result, different actors may be pulling the initiative in different directions, undermining the overall partnership efforts. In this short contribution a strategic scoping canvas and an associated facilitation process are presented as a way of addressing such situations. Illustrations are provided of initial application in three cases related to food system transitions in Peru, Ethiopia, and Bangladesh, exploring the connectivity with approaches commonly used in the context of system transformations, including the Multi-Level Perspective on sustainability transitions, the Leverage Points approach, Capability Approach, and the theory of Large System Change. We conclude that the canvas and associated facilitation approach has proved useful in different contexts, offering opportunities for complementing existing methodologies, and potentially enhancing their efficacy in facilitated multi-stakeholder processes.

Treasure Chest

To operate within the safe and just operating space captured by the doughnut metaphor, sustainability transitions are needed in the food system. Niche food systems with highly distinct practices and organization constitute a treasure chest of alternatives from which society can build new futures. Policy has little awareness of niche food systems and their potential contributions to sustainability transitions. Importantly, this limits society’s ability to adapt. Here, we review findings from an ongoing scientific project into different components of the vegetable food systems in Chile and Uruguay. The aim of the project is to investigate options for transitioning to low- or no-pesticide vegetable food systems. The results show: 1. the presence of promising alternative vegetable food systems in Chile, which are, however, highly marginalized and disempowered; 2. a diversity of vertical and horizontal producer arrangements in Uruguay and the need for value-driven as well as market-driven engagement; and 3. major possibilities for improving production systems to arrive within the doughnut by taking a systems perspective at the farm scale that includes the farm families and their networks. Consequences of these findings for alternative vegetable food systems are discussed.

We present a case study on digitalization of Southern Rock Art (“Arte Sureño”) in a prehistoric rock shelter from Los Barrios, Cádiz (southern Iberian Peninsula); there we use SfM techniques to obtain some digital products for both analytic and divulgation goals. This way, we highlight some opportunities that low-cost devices (e.g. no-professional digital camera) and open software have introduced in archaeology today. We made it to converge in a working process to register and manage rock art expressions and their immediate surroundings (i.e. natural stone blocks, walls, niches…). From this action, we not only support our work in digital 3D about multiple and varied entities that make up the scenario and neighbour context of rock art through the use of multiple low cost / free resources, but also, we intend to adjust all this operative for the processes of investigation, protection and diffusion on the varied cases that make up this unique singular artistic heritage.http://dx.doi.org/10.4995/CIGeo2017.2017.6658

Organizational learning, knowledge creation, retention, and diffusion are strategies that open many a window of opportunities for organizations to differentiate themselves in the global economy. However, performance based on knowledge has not yet become exposed. Intangible assets must be continuously analyzed to reach organizational performance and sustainability. New management and economic literature reveals that communities of practice focus on humanized leadership and self-efficacy that promote added value to the organization. Furthermore, the humanisation of the organization perspective becomes the nucleus and the framework for all levels of productivity and competitiveness. This chapter posits different organizational learning pathways according to a holistic perspective with humanisation as a unique element. The chapter is centered on an analysis of the human capital construct as the point of departure. Furthermore, the chapter reflects on humanized and humanising emotional, spiritual, and relational capital in order to reach the level of organizational knowledge.
