Waste electrical and electronic equipment (or e-waste) is one of the fastest growing waste streams, which encompasses a wide and increasing spectrum of products. Accurate estimation of e-waste generation is difficult, mainly due to lack of high quality data referred to market and socio-economic dynamics. This paper addresses how to enhance e-waste estimates by providing techniques to increase data quality. An advanced, flexible and multivariate Input–Output Analysis (IOA) method is proposed. It links all three pillars in IOA (product sales, stock and lifespan profiles) to construct mathematical relationships between various data points. By applying this method, the data consolidation steps can generate more accurate time-series datasets from available data pool. This can consequently increase the reliability of e-waste estimates compared to the approach without data processing. A case study in the Netherlands is used to apply the advanced IOA model. As a result, for the first time ever, complete datasets of all three variables for estimating all types of e-waste have been obtained. The result of this study also demonstrates significant disparity between various estimation models, arising from the use of data under different conditions. It shows the importance of applying multivariate approach and multiple sources to improve data quality for modelling, specifically using appropriate time-varying lifespan parameters. Following the case study, a roadmap with a procedural guideline is provided to enhance e-waste estimation studies.

We previously demonstrated that intake of low‐fat dairy, but not high‐fat dairy, was associated with a decreased colorectal cancer (CRC) recurrence risk. These risks, however, may differ by sex, ...primary tumour location, and disease stage. Combining data from two similar prospective cohort studies of people with stage I–III CRC enabled these subgroup analyses. Participants completed a food frequency questionnaire at diagnosis (n = 2283). We examined associations between low‐ and high‐fat dairy intake and recurrence risk using multivariable Cox proportional hazard models, stratified by sex, and primary tumour location (colon and rectum), and disease stage (I/II and III). Upper quartiles were compared to lower quartiles of intake, and recurrence was defined as a locoregional recurrence and/or metastasis. During a median follow‐up of 5.0 years, 331 recurrences were detected. A higher intake of low‐fat dairy was associated with a reduced risk of recurrence (hazard ratio HR: 0.60, 95% confidence interval CI: 0.43–0.83), which seemed more pronounced in men (HR: 0.51, 95% CI: 0.34–0.77) than in women (HR: 0.84, 95% CI: 0.47–1.49). A higher intake of high‐fat dairy was associated with an increased risk of recurrence in participants with colon cancer (HR: 1.60, 95% CI: 1.03–2.50), but not rectal cancer (HR: 0.88, 95% CI: 0.54–1.45). No differences in associations were observed between strata of disease stage. Concluding, our findings imply that dietary advice regarding low‐fat dairy intake may be especially important for men with CRC, and that dietary advice regarding high‐fat dairy intake may be specifically important in people with colon cancer.
What's new?
There is strong evidence that dairy intake is associated with a reduced risk of developing colorectal cancer. However, its relation to the risk of colorectal cancer recurrence remains unclear. Combining data from two prospective cohort studies of patients with stage I–III colorectal cancer, this study found that a higher intake of low‐fat dairy was associated with a reduced risk of recurrence in men, where as a higher intake of high‐fat dairy was associated with an increased risk of recurrence in people with colon cancer. With a global transition towards more plant‐based diets and increasing numbers of colorectal cancer survivors, the findings may contribute to more personalised dietary guidelines.

This Open Access book provides a thorough analysis of the quality of work in the Netherlands, and suggests policy proposals to promote and facilitate good work for more people. New technology, ...flexibilization and the intensification of work will have significant consequences for all those who will still have jobs in the future, and – much less studied so far – for the quality of their work. Good work is essential for general well-being: for the individual’s quality of life, for the economy and for society. Good work for everyone should therefore be seen as an important aspiration for companies, institutions, social partners and governments. An essential read for an international audience of academics in the field of the sociology of work, labor economics and social policy, as well as for policymakers and researchers of trade unions, and representatives of other social movements.
This open access book offers an analysis of why preparations for digital disruption should become a stated goal of security policy and policies that aim to safeguard the continuity of critical ...infrastructure. The increasing use of digital technology implies new and significant vulnerabilities for our society. However, it is striking that almost all cyber-security measures taken by governments, international bodies and other major players are aimed at preventing incidents. But there is no such thing as total digital security. Whether inside or outside the digital domain, incidents can and will occur and may lead to disruption. While a raft of provisions, crisis contingency plans and legal regulations are in place to deal with the possibility of incidents in the ‘real world’, no equivalence exists for the digital domain and digital disruption. Hence, this book uniquely discusses several specific policy measures government and businesses should take in order to be better prepared to deal with a digital disruption and prevent further escalation.
