    On the Sustainability of Web Systems Evolution

    In the last twenty years, the evolution of web systems has been driven along three dimensions: the processes used to develop, evolve, maintain and re-engineer the systems themselves; the end products (the pages, content and links) of such processes; and finally the people dimension, with the extraordinary shift in how developers and users shape, interact and maintain the code and content that they put online. This paper reviews the questions that each of these dimensions has addressed in the past, and indicates which ones will need to be addressed in the future, in order for web system evolution to be sustainable. We show that the study on websites evolution has shifted from server- to client-side, focusing on better technologies and processes, and that the users becoming creators of content open several open questions, in particular the issue of credibility of the content created and the sustainability of such resources in the long term

    Contextual impacts on industrial processes brought by the digital transformation of manufacturing: a systematic review

    The digital transformation of manufacturing (a phenomenon also known as "Industry 4.0" or "Smart Manufacturing") is finding a growing interest both at practitioner and academic levels, but is still in its infancy and needs deeper investigation. Even though current and potential advantages of digital manufacturing are remarkable, in terms of improved efficiency, sustainability, customization, and flexibility, only a limited number of companies has already developed ad hoc strategies necessary to achieve a superior performance. Through a systematic review, this study aims at assessing the current state of the art of the academic literature regarding the paradigm shift occurring in the manufacturing settings, in order to provide definitions as well as point out recurring patterns and gaps to be addressed by future research. For the literature search, the most representative keywords, strict criteria, and classification schemes based on authoritative reference studies were used. The final sample of 156 primary publications was analyzed through a systematic coding process to identify theoretical and methodological approaches, together with other significant elements. This analysis allowed a mapping of the literature based on clusters of critical themes to synthesize the developments of different research streams and provide the most representative picture of its current state. Research areas, insights, and gaps resulting from this analysis contributed to create a schematic research agenda, which clearly indicates the space for future evolutions of the state of knowledge in this field

    Software Challenges For HL-LHC Data Analysis

    The high energy physics community is discussing where investment is needed to prepare software for the HL-LHC and its unprecedented challenges. The ROOT project is one of the central software players in high energy physics since decades. From its experience and expectations, the ROOT team has distilled a comprehensive set of areas that should see research and development in the context of data analysis software, for making best use of HL-LHC's physics potential. This work shows what these areas could be, why the ROOT team believes investing in them is needed, which gains are expected, and where related work is ongoing. It can serve as an indication for future research proposals and cooperations

    Teaching geography for a sustainable world: a case study of a secondary school in Spain

    Get PDF
    Geography has a major responsibility in delivering education for sustainable development (ESD), especially because the geographical concepts of place and space are key dimensions for the analysis and pursuit of sustainability. This paper presents the results of a research that investigated how the teaching of geography in secondary education in Catalonia (Spain) contributes to ESD. For the development of this research it was explored what is involved in understanding and resolving issues about sustainable development and how geography teachers might best conceptualize and teach in this new domain. As a result of this theoretical reflection it has been defined a proposal or model for reorienting the geography curriculum from the basis of the ESD paradigm, which is based and structured in four groups of criteria and recommendations as follows: recommendations for defining competences and learning objectives; criteria for selecting geographical contents and themes; criteria for selecting geographical areas and for the use of scale; and finally, recommendations for choosing the most suitable teaching and learning approach
