Prevalent as bird imagery is in the ritual traditions of eastern North America, the bony remains of birds are relatively sparse in archaeological deposits and when present are typically viewed as subsistence remains. A first-millennium ad civic-ceremonial centre on the northern Gulf Coast of Florida contains large pits with bird bones amid abundant fish bone and other taxa. The avian remains are dominated by elements of juvenile white ibises, birds that were taken from offshore rookeries at the time of summer solstices. The pits into which they were deposited were emplaced on a relict dune with solstice orientations. The timing and siting of solstice feasts at this particular centre invites discussion of world-renewal rituality and the significance of birds in not only the timing of these events but also possibly as agents of balance and rejuvenation.

Organismal metabolic rates reflect the interaction of environmental and physiological factors. Thus, calcifying organisms that record growth history can provide insight into both the ancient environments in which they lived and their own physiology and life history. However, interpreting them requires understanding which environmental factors have the greatest influence on growth rate and the extent to which evolutionary history constrains growth rates across lineages. We integrated satellite measurements of sea-surface temperature and chlorophyll-a concentration with a database of growth coefficients, body sizes, and life spans for 692 populations of living marine bivalves in 195 species, set within the context of a new maximum-likelihood phylogeny of bivalves. We find that environmental predictors overall explain only a small proportion of variation in growth coefficient across all species; temperature is a better predictor of growth coefficient than food supply, and growth coefficient is somewhat more variable at higher summer temperatures. Growth coefficients exhibit moderate phylogenetic signal, and taxonomic membership is a stronger predictor of growth coefficient than any environmental predictor, but phylogenetic inertia cannot fully explain the disjunction between our findings and the extensive body of work demonstrating strong environmental control on growth rates within taxa. Accounting for evolutionary history is critical when considering shells as historical archives. The weak relationship between variation in food supply and variation in growth coefficient in our data set is inconsistent with the hypothesis that the increase in mean body size through the Phanerozoic was driven by increasing productivity enabling faster growth rates.

We agree with Rotolo et al.’s (2018) assertion that talent management is a space where the academic–practice gap in industrial and organizational (I-O) psychology is quite cavernous and where the vulnerabilities to anti-I-O (AIO) are high. As researchers who began a journey a few years ago to explore the high potential (HiPo) identification process from the science perspective (largely inspired by Silzer & Church, 2009), we echo the frustration that the current focal authors express with the science-side lag in this area. For us, what started as a question from a senior officer in the Army turned into the development of a theoretical model and the start of multilocation research lab designed to further the understanding and success of the HiPo identification process. Our objective is to share a bit of our journey that got us to this point and some lessons for others inspired by this focal article to become anti-anti-I-O (AAIO) warriors.

Network meta-analysis (NMA) is a statistical technique for making direct and indirect comparisons between different treatment and control groups. Despite its many advantages, NMA may be misleading when evaluating networks that are disconnected, inconsistent or of low reliability and validity. We review how well the analysis of trials of adjunctive psychosocial treatment in bipolar disorder is served by NMA. We conclude with recommendations for future treatment trials in bipolar disorder and guidelines for NMAs.

Invasive plants have devastating effects on ecosystems and biodiversity that early intervention can prevent. Eradication or containment of new invasions is difficult to achieve because of constraints posed by the low density and detectability of individuals. Domestic dogs trained to cue on distinctive scents might provide an effective method to detect spotted knapweed. The objective of this study was to compare the accuracy and detection distances of dogs to humans in locating new spotted knapweed (Centaurea stoebe) invasions. Three dogs, trained to detect knapweed using scent discrimination and tracking techniques, were compared with human surveyors. Seven sampling units (0.5 ha [1.2 ac]) were delineated in a grazed dryland pasture. Dogs, with their handlers, and human surveyors performed line-transect surveys in fall 2005 and spring, summer, and fall 2006. Dog accuracy for large-size knapweed targets (infestations 0.52 m3 [18.4 ft3]) was similar to human accuracy and better than humans (94 vs. 78%) for medium-size targets (infestations 0.13m3). Dog accuracy (67%) was greater (> 81% probability) than humans (34%) for small targets (plants; 0.02 m3). Overall dog accuracy (81%) and F-measure scores (86%) were better than human scores, 59% and 74%, respectively. Human precision was greater (100%) than dogs at 94%. Dogs detected a larger percentage of small targets (80%) at distances greater than 7.9 m (26 ft) compared with humans at only 20%. Our results indicate dogs are more accurate than humans are, especially at critical detection of small spotted knapweed plants, and from greater distances. Invasive plant monitoring using detection dogs can provide greater overall accuracy of plant detection.

Despite strong evidence in the wider study of electoral behaviour that party campaigning can have important effects on performance, and a large pan-European literature on populist radical right and extreme right campaigns, we know very little about the impact of the latter on electoral performance. Drawing on a range of innovative campaign-related data at the aggregate and individual level, we examine the electoral impact of the British National Party (BNP) at the 2010 British general election. Our analysis reveals that whereas the extreme right polled strongest in working class manufacturing areas, support for the extreme right was significantly higher in areas where it ran intensive local campaigns, recruited larger numbers of members, has achieved local electoral success, and where local politics has historically been dominated by the centre-left. However, we find little evidence that the extreme right has benefited electorally in areas where the English Defence League social movement had previously demonstrated. Our aggregate level findings are also confirmed at the individual level after controlling for a battery of established attitudinal predictors of extreme right voting. Those contacted by the BNP campaign were significantly more likely to vote for the party, while campaigning by all other political parties was ineffective in reducing the probability of voting BNP.

This article looks at ways in which communal area right holders in Zimbabwe attempt to add security to their land rights when faced with altered circumstances. Apart from quasi-legal means such as ad hoc diagrams, which were beyond the scope of this article, two principal strands were found by which land right security is bolstered. First, investment in interpersonal ties (both with the living and the dead), and second, ceremonies for forging and maintaining links with land. For both, it was found that traditional practices have been bent and adapted pragmatically to suit contemporary contexts. Increased mobility and remoteness from rural homes have also given rise to a degree of abstraction (for example, the symbolic use in urban settings of soil or grain brought from communal areas). Where both custom and formal law coexist pluralistically, custom has proved the more flexible of the two and, unless demonstrably better security is offered, it seems likely that custom will continue to be invoked and modified to provide security for new circumstances.

Several theoretical studies have suggested that large samples of randomly ascertained siblings can be efficiently used to ascertain phenotypically extreme individuals and increase power to detect genetic linkage. Phenotypes that can be reliably measured by questionnaire are of obvious utility for such selection strategies, as large numbers of individuals can be contacted without laborious individual interview. As the first step in developing a large randomly-ascertained family cohort in southwest England, a sample of 88 000 individuals, including more than 34 000 sibling pairs in 20 000 sibships, was administered the Eysenck Personality Questionnaire (EPQ) by commercial mailing. The sample age ranges were 20–67 years and comprised 59% males and 41% females. Descriptive properties of the EPQ scales are similar to those reported from other large family cohorts. Test–retest correlations on 1681 probands in the sample are substantial for the N-scale (r = 0.93), but somewhat more modest for the other scales (range r = 0.70–0.88). Phenotypic and sibling correlations correspond quite closely to those of twin studies. Twin Research (2000) 3, 310–315.
