- Accurate prediction of community responses to global change drivers (GCDs) is critical given the effects of biodiversity on ecosystem services. There is consensus that human activities are driving species extinctions at the global scale, but debate remains over whether GCDs are systematically altering local communities worldwide. Across 105 experiments that included over 400 experimental manipulations, we found evidence for a lagged response of herbaceous plant communities to GCDs caused by shifts in the identities and relative abundances of species, often without a corresponding difference in species richness. These results provide evidence that community responses are pervasive across a wide variety of GCDs on long-term temporal scales and that these responses increase in strength when multiple GCDs are simultaneously imposed.Global change drivers (GCDs) are expected to alter community structure and consequently, the services that ecosystems provide. Yet, few experimental investigations have examined effects of GCDs on plant community structure across multiple ecosystem types, and those that do exist present conflicting patterns. In an unprecedented global synthesis of over 100 experiments that manipulated factors linked to GCDs, we show that herbaceous plant community responses depend on experimental manipulation length and number of factors manipulated. We found that plant communities are fairly resistant to experimentally manipulated GCDs in the short term (<10 y). In contrast, long-term (≥10 y) experiments show increasing community divergence of treatments from control conditions. Surprisingly, these community responses occurred with similar frequency across the GCD types manipulated in our database. However, community responses were more common when 3 or more GCDs were simultaneously manipulated, suggesting the emergence of additive or synergistic effects of multiple drivers, particularly over long time periods. In half of the cases, GCD manipulations caused a difference in community composition without a corresponding species richness difference, indicating that species reordering or replacement is an important mechanism of community responses to GCDs and should be given greater consideration when examining consequences of GCDs for the biodiversity–ecosystem function relationship. Human activities are currently driving unparalleled global changes worldwide. Our analyses provide the most comprehensive evidence to date that these human activities may have widespread impacts on plant community composition globally, which will increase in frequency over time and be greater in areas where communities face multiple GCDs simultaneously.

- Throughout the middle decades of the 20th Century Indigenous people were the target of efforts to assist in economic development. In large part these externally developed, modernisation based efforts failed. In response, a second wave of Indigenous development has emerged; one in which Indigenous peoples are striving to rebuild their 'nations' and improve their lot through economic development 'on their own terms'. Key to this approach is the pursuit by Indigenous people of the recognition of their rights to their traditional lands and resources. This paper examines the emergence of this second wave of Indigenous development in Canada.

- Purpose: The aim of this work was to qualitatively explore the personal perspectives of prosthetic and orthotic users, in the context of their past and present experiences and understand their insights for the future.Materials and Methods: A narrative exploration study design employing a phenomenological approach was used. Semi-structured interviews were conducted with three female and two male prosthetic and orthotic users from Australia and the United Kingdom. Interviews were analysed, coded and key themes and sub-themes identified. Results: Three themes were identified. The Maximising Opportunity theme linked sub-themes of recreation and pushing boundaries. The Health Care Network theme included sub-themes of communication, peer support and building a team. The final theme, Changes over time, included sub-themes of disability perception, advice and advancements over time. Conclusion: Prosthetic and orthotic users identified there had been vast changes in disability perception, disability rights, and their role in the health care system, along with the variety of technology and materials available. Key findings were that prosthetic and orthotic users want to be listened to, considered central to the health care team, and had a deep understanding of their own health care needs.

- Indigenous populations throughout the world suffer from chronic poverty, lower education levels, and poor health. The 'second wave' of indigenous development, after direct economic assistance from outside, lies in indigenous efforts to rebuild their 'nations' and improve their lot through entrepreneurial enterprise. This paper suggests that there is a distinguishable kind of activity appropriately called 'indigenous entrepreneurship'. We begin by defining the indigenous population and noting some general facts about their numbers and distribution. In an effort to discern the potential for development on indigenous peoples' own terms, we then explore three frameworks for understanding efforts at development, including indigenous development: modernisation theory, dependency theory and (at somewhat greater length) regulation theory. After distinguishing 'indigenous' from 'ethnic' entrepreneurship, we conclude by identifying a number of lead questions that present themselves at the outset of an enquiry into the nature of indigenous entrepreneurship.
