It is estimated that 2.5-10 bn disposable coffee cups are used every year in the U.K. Most of these cups end up in landfill or as litter, as the majority of poly-coated paper cups are not recyclable or not recycled. Here, we report on a field experiment that was conducted at twelve university and business sites to examine whether the use of reusable cups can be promoted through easily implementable measures. The study found that both environmental messaging and the provision of alternatives increased the use of reusable cups. While a charge on disposable cups increased their use as well, a discount on reusable cups did not. The effects for the individual measures were modest, but additive, meaning that the greatest behavioural change was achieved with a combination of measures. None of the measures negatively impacted the total number of hot drink sales. One university continued with the charge after the experiment had finished and distributed more reusable cups for free among their students. This boosted the use of reusable cups up to 33.7% across three cafés. This shows that a charge in combination with the provision of alternatives can increase the use of reusable cups substantially in the long term.

When graduates of Australian social work courses embark on a career in mental health, the systems they enter are complex, fragmented and evolving. Emerging practitioners will commonly be confronted by the loneliness, social exclusion, poverty and prejudice experienced by people living with mental distress; however, social work practice may not be focused on these factors. Instead, in accordance with the dominant biomedical perspective, symptom and risk management may predominate. Frustration with the limitations evident in this approach has seen the United Nations call for the transformation of mental health service delivery. Recognising paradigmatic influences on mental health social work may lead to a more considered enactment of person centred, recovery and rights-based approaches. This paper compares and contrasts influences of neo-liberalism, critical theory, human rights and post-structuralism on mental health social work practice. In preparing social work practitioners to recognise the influence of, and work more creatively with, intersecting paradigms, social work educators strive to foster a transformative approach to mental health practice that straddles discourses.
