The term Anthropocene, proposed and increasingly employed to denote the current interval of anthropogenic global environ- mental change, may be discussed on stratigraphic grounds. A case can be made for its consideration as a formal epoch in that, since the start of the Industrial Revolution, Earth has endured changes sufficient to leave a global stratigraphic signature dis- tinct from that of the Holocene or of previous Pleistocene inter- glacial phases, encompassing novel biotic, sedimentary, and geochemical change. These changes, although likely only in their initial phases, are sufficiently distinct and robustly estab- lished for suggestions of a Holocene-Anthropocene bound- ary in the recent historical past to be geologically reasonable. The boundary may be defined either via Global Stratigraphic Section and Point ("golden spike") locations or by adopting a numerical date. Formal adoption of this term in the near future will largely depend on its utility, particularly to earth scientists working on late Holocene successions. This datum, from the perspective of the far future, will most probably approximate a distinctive stratigraphic boundary.

Mindfulness-based Cognitive Therapy (MBCT) is a meditation-based intervention designed to reduce recurrence in people with histories of relapsing unipolar major depression. MBCT is an eight-session course delivered to groups of participants who are currently not (or only mildly) depressed. We sought to determine whether MBCT is suitable for older people, and what modifications they may require. We recruited 38 participants aged over 65, of whom 30 completed an MBCT course. Their responses at assessment, post-course and one-year follow-up interviews, plus comments at three-monthly ‘reunion’ meetings, provided data for thematic analysis. Main themes emerging for participants as a group are considered, as are individuals’ understandings and uses of MBCT, and how these developed during and following the course. We found MBCT promising as a cost-effective addition to clinicians’ repertoire for addressing depression in old age, and identified issues for further research. Participants’ comments indicated that they considered MBCT a helpful intervention for older sufferers from recurring depression.
Today Adam Smith's reputation rests on his explanation of how rational self-interest in a free-market economy leads to economic well-being. It may surprise those who would discount Smith as an advocate of ruthless individualism that his first major work concentrates on ethics and charity. In fact, while chair at the University of Glasgow, Smith's lecture subjects, in order of preference, were natural theology, ethics, jurisprudence, and economics, according to John Millar, Smith's pupil at the time. In The Theory of Moral Sentiments, Smith wrote: "How selfish soever man may be supposed, there are evidently some principles in his nature which interest him in the fortune of others and render their happiness necessary to him though he derives nothing from it except the pleasure of seeing it." The Theory of Moral Sentiments establishes the intellectual framework for all of Smith's later work, including the monumental Wealth of Nations.
