This essay argues that we have a duty to protect biodiversity hotspots, rooted in an argument about the wrongful imposition of risk and intergenerational justice. State authority over territory and resources is not unlimited; the state has a duty to protect these areas. The essay argues that although biodiversity loss is a global problem, it can be tackled at the domestic level through clear rules. The argument thus challenges the usual view of state sovereignty, which holds that authority over territory, resources, and migration (all of which are connected to the protection of biodiversity hotspots) is unlimited.

Peer support interventions for dietary change may offer cost-effective alternatives to interventions led by health professionals. This process evaluation of a trial to encourage the adoption and maintenance of a Mediterranean diet in a Northern European population at high CVD risk (TEAM-MED) aimed to investigate the feasibility of implementing a group-based peer support intervention for dietary change, positive elements of the intervention and aspects that could be improved. Data on training and support for the peer supporters; intervention fidelity and acceptability; acceptability of data collection processes for the trial and reasons for withdrawal from the trial were considered. Data were collected from observations, questionnaires and interviews, with both peer supporters and trial participants. Peer supporters were recruited and trained to result in successful implementation of the intervention; all intended sessions were run, with the majority of elements included. Peer supporters were complimentary of the training, and positive comments from participants centred around the peer supporters, the intervention materials and the supportive nature of the group sessions. Attendance at the group sessions, however, waned over the intervention, with suggested effects on intervention engagement, enthusiasm and group cohesion. Reduced attendance was reportedly a result of meeting (in)frequency and organisational concerns, but increased social activities and group-based activities may also increase engagement, group cohesion and attendance. The peer support intervention was successfully implemented and tested, but improvements can be suggested and may enhance the successful nature of these types of interventions. Some consideration of personal preferences may also improve outcomes.

This article is about Indigenous territorial title and land rights, and specifically those of the Algonquin Anishinaabeg Nation. In 1983, the Algonquins of Pikwàkanagàn, residing in the province of Ontario, petitioned the Crown to recognize Algonquin territorial title and rights to 36,000 square kilometres of their natal homelands in the Ottawa River watershed. With negotiations beginning in the early 1990s, an Agreement-in-Principle was developed and ratified in 2016, the penultimate step to the largest modern treaty in Ontario's history. In this article, we examine the argument for moral rights to territory, not in terms of the Canadian or international legal order, nor even through examining the documents and voice of the Algonquin Anishinaabeg, but through the lens of an argument that has been advanced as the basis of the international territorial rights of states. We argue that the justifications for state rights territory—grounded in the considerations that ensue from an analysis of occupancy groups—provides a stronger claim to territorial jurisdiction and title in the case of the Algonquin Anishinaabeg Nation than the competing claim by the Canadian state.

This study aimed to evaluate the feasibility of a peer support intervention to encourage adoption and maintenance of a Mediterranean diet (MD) in established community groups where existing social support may assist the behaviour change process. Four established community groups with members at increased Cardiovascular Disease (CVD) risk and homogenous in gender were recruited and randomised to receive either a 12-month Peer Support (PS) intervention (PSG) (n 2) or a Minimal Support intervention (educational materials only) (MSG) (n 2). The feasibility of the intervention was assessed using recruitment and retention rates, assessing the variability of outcome measures (primary outcome: adoption of an MD at 6 months (using a Mediterranean Diet Score (MDS)) and process evaluation measures including qualitative interviews. Recruitment rates for community groups (n 4/8), participants (n 31/51) and peer supporters (n 6/14) were 50 %, 61 % and 43 %, respectively. The recruitment strategy faced several challenges with recruitment and retention of participants, leading to a smaller sample than intended. At 12 months, a 65 % and 76·5 % retention rate for PSG and MSG participants was observed, respectively. A > 2-point increase in MDS was observed in both the PSG and the MSG at 6 months, maintained at 12 months. An increase in MD adherence was evident in both groups during follow-up; however, the challenges faced in recruitment and retention suggest a definitive study of the peer support intervention using current methods is not feasible and refinement based on the current feasibility study should be incorporated. Lessons learned during the implementation of this intervention will help inform future interventions in this area.

Adhering to a Mediterranean diet (MD) is associated with reduced CVD risk. This study aimed to explore methods of increasing MD adoption in a non-Mediterranean population at high risk of CVD, including assessing the feasibility of a developed peer support intervention. The Trial to Encourage Adoption and Maintenance of a MEditerranean Diet was a 12-month pilot parallel group RCT involving individuals aged ≥ 40 year, with low MD adherence, who were overweight, and had an estimated CVD risk ≥ 20 % over ten years. It explored three interventions, a peer support group, a dietician-led support group and a minimal support group to encourage dietary behaviour change and monitored variability in Mediterranean Diet Score (MDS) over time and between the intervention groups, alongside measurement of markers of nutritional status and cardiovascular risk. 118 individuals were assessed for eligibility, and 75 (64 %) were eligible. After 12 months, there was a retention rate of 69 % (peer support group 59 %; DSG 88 %; MSG 63 %). For all participants, increases in MDS were observed over 12 months (P < 0·001), both in original MDS data and when imputed data were used. Improvements in BMI, HbA1c levels, systolic and diastolic blood pressure in the population as a whole. This pilot study has demonstrated that a non-Mediterranean adult population at high CVD risk can make dietary behaviour change over a 12-month period towards an MD. The study also highlights the feasibility of a peer support intervention to encourage MD behaviour change amongst this population group and will inform a definitive trial.

Eliciting honest answers to sensitive questions is frustrated if subjects withhold the truth for fear that others will judge or punish them. The resulting bias is commonly referred to as social desirability bias, a subset of what we label sensitivity bias. We make three contributions. First, we propose a social reference theory of sensitivity bias to structure expectations about survey responses on sensitive topics. Second, we explore the bias-variance trade-off inherent in the choice between direct and indirect measurement technologies. Third, to estimate the extent of sensitivity bias, we meta-analyze the set of published and unpublished list experiments (a.k.a., the item count technique) conducted to date and compare the results with direct questions. We find that sensitivity biases are typically smaller than 10 percentage points and in some domains are approximately zero.

This article is interested in the general question of what justifies territorial rights over unoccupied places, including places that are not occupied but are situated within the territorial borders of a state. This question arises because one of the most common defenses of rights over territory makes use of the idea of occupancy and has difficulty explaining such rights in places that are not occupied. It explores this question through an examination of the claims and arguments in the Canadian Arctic, which provides an historically specific test case for the merits and plausibility of the various arguments appealed to. It argues that territorial rights in unoccupied places, including the Canadian Arctic, are justified on different grounds than in occupied parts of the territory, and that the justification also affects the kinds of rights—particularly over resources—that such states can claim.

First, let me say that it is a pleasure to be asked to comment on the work of Walker Connor, who is a huge figure in the study of nationalism, and has been tremendously influential for me both personally and in my own work. Let me say something personal, first. In the spring of 2005, Walker Connor came to my home university, Queen's University in Kingston, Canada, as a Fulbright Fellow. This was our first Fulbright Fellow and we were thrilled to have an international star in nationalism join us. He was witty, humorous, smart, and very, very kind. He was also – I was struck by this – very generous with his time, with students, and with junior scholars. He talked at length to our graduate students who were working on nationalism. He told me that he enjoyed students very much, and that in his opinion the American liberal arts colleges were excellent places to work because one could see the impact of one's ideas and challenges on students.

Motivated by the local theory of Banach spaces, we introduce a notion of finite representability for metric spaces. This allows us to develop a new technique for comparing the generalised roundness of metric spaces. We illustrate this technique by applying it to Banach spaces and metric trees. In the realm of Banach spaces we obtain results such as the following: (1) if ${\mathcal{U}}$ is any ultrafilter and $X$ is any Banach space, then the second dual $X^{\ast \ast }$ and the ultrapower $(X)_{{\mathcal{U}}}$ have the same generalised roundness as $X$, and (2) no Banach space of positive generalised roundness is uniformly homeomorphic to $c_{0}$ or $\ell _{p}$, $2<p<\infty$. For metric trees, we give the first examples of metric trees of generalised roundness one that have finite diameter. In addition, we show that metric trees of generalised roundness one possess special Euclidean embedding properties that distinguish them from all other metric trees.

The purpose of the study examined in this article was to understand how non-physician health care professionals working in Canadian primary health care settings facilitate older persons’ access to community support services (CSSs). The use of CSSs has positive impacts for clients, yet they are underused from lack of awareness. Using a qualitative description approach, we interviewed 20 health care professionals from various disciplines and primary health care models about the processes they use to link older patients to CSSs. Participants collaborated extensively with interprofessional colleagues within and outside their organizations to find relevant CSSs. They actively engaged patients and families in making these linkages and ensured follow-up. It was troubling to find that they relied on out-of-date resources and inefficient search strategies to find CSSs. Our findings can be used to develop resources and approaches to better support primary health care providers in linking older adults to relevant CSSs.

Results of protein residue and lithic microwear analyses are reported for Paleoindian and Early Archaic stone tools from a Carolina bay sand rim on the Aiken Plateau of South Carolina, USA. Protein residue analysis is performed using crossover Immunoelectrophoresis (CIEP), and indicates positive results for Bovidae, Cervidae, Galliformes, and Meleagris gallopavo. These results are complemented by a larger immunological study of 135 diagnostic hafted bifaces from South Carolina and Georgia. Among other species identified, bovid residue was found on multiple Paleoindian hafted bifaces, an Early Archaic hafted biface, and a Middle Archaic hafted biface. Results suggest continuity of species selection and availability across the Pleistocene/Holocene boundary and provide no support for the exploitation of extinct fauna. The data do provide compelling evidence for a demographic shift and/or regional extirpation of Bovidae possibly as late as the early mid-Holocene in the Southeast. In addition, microwear analysis of artifacts from Flamingo Bay indicate intensive hide scraping, antler boring, bone graving/planing/pointing, wood whittling, and hafting traces. Microwear data suggest intentional snap-fracture or bipolarization of exhausted or broken Clovis points for reuse as hide scrapers, and use of large bifacial knives and unifacial scrapers in intensive defleshing activities consistent with large animal butchery.
