    Digital inequalities and social media: Experiences of young people in Chile

    Purpose – This paper aims to report the findings from a survey of secondary school students in Chile by exploring their use of social networking services for information-seeking purposes. Design/methodology/approach – An online survey was distributed via Chile’s Ministry of Education and 12,354 responses were received. Findings – The results indicate that young people in Chile extensively use SNSs, but there are differences in the ways in which they use these services, specifically for information purposes. When considering schoolrelated activities, there are differences in the use of SNSs by students in different types of schools. Those in academic-focussed institutions are more likely to use SNSs for school-related information purposes and are more likely to publish most types of information on SNSs than their counterparts in vocational schools. Research limitations/implications – The sample was self-selecting and excluded students without online access to the survey. Practical implications – The findings indicate more needs to be done in schools serving lower socioeconomic communities to support students’ use of SNSs for information-seeking, especially for academic purposes. Social implications – The findings suggest that school-associated social capital may have a role in shaping students’ use of SNSs for information and learning purposes and, potentially, in exacerbating digital inequalities. Originality/value – The focus on the use of social media specifically for information-seeking distinguishes this research. The findings challenge possible assumptions about the links between social media use and social class and suggest that differences may be exacerbated by school practices

    To what extent has Sustainable Intensification in England been achieved?

    Agricultural intensification has significantly increased yields and fed growing populations across the planet, but has also led to considerable environmental degradation. In response an alternative process of ‘Sustainable Intensification’ (SI), whereby food production increases while environmental impacts are reduced, has been advocated as necessary, if not sufficient, for delivering food and environmental security. However, the extent to which SI has begun, the main drivers of SI, and the degree to which degradation is simply ‘offshored’ are uncertain. In this study we assess agroecosystem services in England and two contrasting sub-regions, majority-arable Eastern England and majority-pastoral South-Western England, since 1950 by analysing ecosystem service metrics and developing a simple system dynamics model. We find that rapid agricultural intensification drove significant environmental degradation in England in the early 1980s, but that most ecosystem services except farmland biodiversity began to recover after 2000, primarily due to reduced livestock and fertiliser usage decoupling from high yields. This partially follows the trajectory of an Environmental Kuznets Curve, with yields and GDP growth decoupling from environmental degradation above ~£17,000 per capita per annum. Together, these trends suggest that SI has begun in England. However, the lack of recovery in farmland biodiversity, and the reduction in UK food self-sufficiency resulting in some agricultural impacts being ‘offshored’, represent major negative trade-offs. Maintaining yields and restoring biodiversity while also addressing climate change, offshored degradation, and post-Brexit subsidy changes will require significant further SI in the future

    Assessing barriers to reuse of electrical and electronic equipment, a UK perspective

    This paper reports on research undertaken to identify generic and specific barriers to reuse of electrical and electronic equipment (EEE). Thirty semi-structured interviews were conducted with experts from across the value chain including product designers, manufacturers, users and waste managers as well policy makers and academics. The interviews sought to examine perceived and real barriers to reuse in the UK. Three inter-connected factors that limit opportunities and instances of reuse of electrical and electronic equipment were identified, highlighting that both systemic and consumer barriers to increasing levels of reuse exist. These are: producer reluctance, unsuitable collection infrastructure and cultural issues. Overall, the paper shows that low levels of reuse in the electrical and electronic sector are a result of complex and interlinked barriers. Understanding these connections offers the potential to improve the opportunities for reuse, by providing direction for policy makers to address barriers from a multi stakeholder perspective. Increasing instances of reuse is essential if the UK is to successfully move towards a resource efficient, circular economy

    Metrics for optimising the multi-dimensional value of resources recovered from waste in a circular economy: A critical review

    Get PDF
    © 2017 The Authors - Established assessment methods focusing on resource recovery from waste within a circular economy context consider few or even a single domain/s of value, i.e. environmental, economic, social and technical domains. This partial approach often delivers misleading messages for policy- and decision-makers. It fails to accurately represent systems complexity, and obscures impacts, trade-offs and problem shifting that resource recovery processes or systems intended to promote circular economy may cause. Here, we challenge such partial approaches by critically reviewing the existing suite of environmental, economic, social and technical metrics that have been regularly observed and used in waste management and resource recovery systems' assessment studies, upstream and downstream of the point where waste is generated. We assess the potential of those metrics to evaluate ‘complex value’ of materials, components and products, i.e., the holistic sum of their environmental, economic, social and technical benefits and impacts across the system. Findings suggest that the way resource recovery systems are assessed and evaluated require simplicity, yet must retain a suitable minimum level of detail across all domains of value, which is pivotal for enabling sound decision-making processes. Criteria for defining a suitable set of metrics for assessing resource recovery from waste require them to be simple, transparent and easy to measure, and be both system- and stakeholder-specific. Future developments must focus on providing a framework for the selection of metrics that accurately describe (or at least reliably proxy for) benefits and impacts across all domains of value, enabling effective and transparent analysis of resource recovery form waste in circular economy systems.We gratefully acknowledge support of the UK Natural Environ-ment Research Council (NERC) and the UK Economic and SocialResearch Council (ESRC) who funded this work in the context of‘Complex Value Optimisation for Resource Recovery’(CVORR)project (Grant No. NE/L014149/1)
