Economic and social impacts of Integrated Aquaculture-Agriculture technologies in Bangladesh

This study estimated the adoption rate of integrated aquaculture-agriculture (IAA) technologies in Bangladesh and their impact on poverty and fish and food consumption in adopting households. We used a novel, simulation-based approach to impact assessment called Tradeoff Analysis for Multi-Dimensional Impact Assessment (TOA-MD). We used the TOA-MD model to demonstrate how it is possible to use available data to estimate adoption rates in relevant populations, and to quantify impacts on distributional outcomes such as poverty and food security, thus demonstrating ex ante the potential for further investment in technology dissemination. The analysis used baseline and end-of-project survey data from WorldFish-implemented Development of Sustainable Aquaculture Project (DSAP), promoting IAA. This dataset was used to simulate adoption and assess its impacts on poverty and food security in the target population. We found that, if adopted, IAA had a significant positive impact on reducing poverty and improving food security and income

Explanation-Giving in a Collaborative Tangible Tabletop Game: Initiation, Positionality, Valence and Action-Orientation

Explanations given to each other by 20 pairs of 5th grade children while playing a tangible tabletop sustainability game were analyzed inductively for key themes relating to their use of language, gesture and system tools. Half the pairs had been assigned roles (human development or natural resources manager) with associated system controls. Findings showed that explanations by pairs in both conditions often employed collectivist language (“we”) in conjunction with positive reflections on the game-world state using the provided Impact Tool which gave feedback while system was paused. Pairs in the roles condition also gave explanations in response to partner actions and more frequently included negative and actionoriented prospective language about what should be changed moving forward. Roles pairs additionally used questions to seek confirmation or action from their partner and made comments from the perspective of the inhabitants of the fictional world. Implications for theresearch and design of collaborative tabletop learning systems are discussed

ASSESSING CLIMATE CHANGE IMPACTS AND ADAPTATION STRATEGIES FOR SMALLHOLDER AGRICULTURAL SYSTEMS IN UGANDA

The debate on whether climate change will impact on peoples\u2019 livelihoods and, hence, the need to act is essentially over and has instead shifted to the development of strategies needed by different regions and countries to adapt to climate change effects. However, there is still scanty information necessary to ably address climate change related issues. There is a considerable knowledge gap with respect to climate change impact, vulnerability and adaptation to increased climate variability and change. In this paper, using the trade off analysis model, the impact of climate change on peoples\u2019 livelihoods and possible adaptation strategies to increase the resilience and sustainability of agricultural systems in three regions of Uganda (central, Masaka and southwest) are analysed. The results show that 70-97% of households will be adversely affected by climate change in Uganda. The southwest will be most affected due to smaller farm sizes and limited livelihood alternatives. There will be no positive gains from encroaching on swamps, which is one of the reported adaptation strategies to climate related stresses. Improving productivity of important crops (bananas for southwest, and sweet potatoes and bananas for central region), in addition to adoption of grade cattle will likely be a better adaptation strategy for climate change.Le d\ue9bat sur le fait que le changement climatique pourra affecter le mode de vie des populations et, ainsi la n\ue9cessit\ue9 d\u2019agir est arriv\ue9 et consiste \ue0 d\ue9velopper des strat\ue9gies en rapport avec les besoins de diff\ue9rentes r\ue9gions et pays pour l\u2019adaptation aux effets du changement climatique. Cependant, les informations disponibles sont encore insuffisantes afin d\u2019adresser correctement les probl\ue8mes y relatifs. Il existe tant de lacunes sur les connaissances en rapport avec les impacts du changement climatique, la vuln\ue9rabilit\ue9 et l\u2019adaptation \ue0 la variabilit\ue9 et changement climatique accrus. En utilisant le mod\ue8le du trade off analysis, cet article a analys\ue9 l\u2019impact du changement climatique sur le mode de vie des populations et des strat\ue9gies possibles d\u2019adaptation, afin d\u2019am\ue9liorer la r\ue9silience et la durabilit\ue9 des syst\ue8mes culturaux dans les trois r\ue9gions de l\u2019Ouganda (Centre, Masaka et sud- ouest). Les r\ue9sultats montrent que 70-97% des m\ue9nages seront touch\ue9s par des effets du changement climatique en Ouganda. Le sud-ouest sera le plus affect\ue9 par suite de tailles petites de ses exploitations et son mode de vie \ue0 moyens alternatifs limit\ue9s. L\u2019invasion des marais ne rapportera aucun gain positif qui est une des strat\ue9gies d\u2019adaptation indiqu\ue9es au stress climatique relatif. L\u2019am\ue9lioration de la productivit\ue9 des cultures importantes (bananiers au Sud-ouest, et les patates douces et le bananier dans la r\ue9gion centrale) en plus de l\u2019adoption des vaches am\ue9lior\ue9es pourra serait une meilleur strat\ue9gie d\u2019adaptation au changement climatique

Child-computer interaction, ubiquitous technologies, and big data

In this forum we celebrate research that helps to successfully bring the benefits of computing technologies to children, older adults, people with disabilities, and other populations that are often ignored in the design of mass-marketed products. The children’s technology landscape is changing quickly. The ubiquity of interactive technologies means children can access them just about anytime, anywhere. At the same time, these technologies constantly collect data from and about children, bringing them into the age of big data, voluntarily or not. These developments have the potential to significantly change children’s relationship to technology and the long-term impact of technology use. To discuss these changes, the child-computer-interaction community held a special interest group (SIG) meeting during the CHI 2018 conference

New Methods to Assess Climate Change Impacts, Vulnerability and Adaptation of Agricultural Production Systems: The experience of AgMIP’s Regional Integrated Assessments in Sub-Saharan Africa and South Asia

The climate change research community has recognized that new pathway and scenario concepts are needed to implement impact and vulnerability assessment that is logically consistent across global, regional and local scales. The most common challenge is that global models do not provide context-specific answers, while scientists and decision makers require data and information about climate change, vulnerability, adaptation, mitigation and impacts at the local scale. The Agricultural Model Inter-comparison and Improvement Project (AgMIP) provides the link between global climate change projections and sector-specific and regional pathways and scenarios (Antle et al., 2015; Rosenzweig et al., 2013). AgMIP, through a trans-disciplinary process involving both scientists and stakeholders, is developing Representative Agricultural Pathways (RAPs) for agricultural systems at both global and regional scales. In addition to climate modeling, RAPs include bio-physical and socio-economic drivers, associated capabilities, challenges and opportunities. RAPs can then be translated as components of the AgMIP Regional Integrated Assessments (RIA) of climate vulnerability and impacts

What can the language of musicians tell us about music interaction design?

It is difficult to create good interaction designs for music software or to substantially improve existing designs. One reason is that music involves diverse and complex concepts, entities, relationships, processes, terminologies, and notations. An open challenge for interaction designers is to find systematic ways of channeling the tacit, specialized knowledge of musicians into designs for intuitive user interfaces that can capably support musically skilled users, without excluding those with less technical musical knowledge. One promising new approach to this challenge involves the application of research from the theory of image schemas and conceptual metaphors This theory has already been applied with some success to analyzing musical concepts, mathematical concepts, general-purpose user-interface design, and sound-generation interaction designs involving simple musical parameters such as tempo, volume, and pitch. We propose that by identifying the conceptual metaphors and image schemas used by musical experts when analyzing an excerpt of music, and then assessing the extent to which these conceptual metaphors are supported by existing music-interaction designs, it is possible to identify areas where the designs do not match musicians’ understanding of the domain concepts. This process provides a principled basis for identifying points at which designs could be improved to better support musicians’ understanding and tasks, and for the provisional identification of possible improvements. We present the results of an analysis of dialogue between three musicians as they discuss an excerpt of music. A methodology for the systematic identification of image schemas and conceptual metaphors is detailed. We report on the use of the results of the dialogue analysis to illuminate the designs of two contrasting examples of music software. Areas in which the designs might be made more intuitive are identified, and corresponding suggestions for improvements are outlined. The present research appears to be the first to investigate the potential of conceptual metaphor theory for investigating and improving music-interaction designs that deal with complex musical concepts, such as harmonic progressions, modulation, and voice leading
