Background
Different diagnostic interviews are used as reference standards for major depression classification in research. Semi-structured interviews involve clinical judgement, whereas fully structured interviews are completely scripted. The Mini International Neuropsychiatric Interview (MINI), a brief fully structured interview, is also sometimes used. It is not known whether interview method is associated with probability of major depression classification.
AimsTo evaluate the association between interview method and odds of major depression classification, controlling for depressive symptom scores and participant characteristics.
MethodData collected for an individual participant data meta-analysis of Patient Health Questionnaire-9 (PHQ-9) diagnostic accuracy were analysed and binomial generalised linear mixed models were fit.
ResultsA total of 17 158 participants (2287 with major depression) from 57 primary studies were analysed. Among fully structured interviews, odds of major depression were higher for the MINI compared with the Composite International Diagnostic Interview (CIDI) (odds ratio (OR) = 2.10; 95% CI = 1.15–3.87). Compared with semi-structured interviews, fully structured interviews (MINI excluded) were non-significantly more likely to classify participants with low-level depressive symptoms (PHQ-9 scores ≤6) as having major depression (OR = 3.13; 95% CI = 0.98–10.00), similarly likely for moderate-level symptoms (PHQ-9 scores 7–15) (OR = 0.96; 95% CI = 0.56–1.66) and significantly less likely for high-level symptoms (PHQ-9 scores ≥16) (OR = 0.50; 95% CI = 0.26–0.97).
ConclusionsThe MINI may identify more people as depressed than the CIDI, and semi-structured and fully structured interviews may not be interchangeable methods, but these results should be replicated.

Introduction
Sudden cardiac death (SCD) is responsible for 5%-10% of all deaths among children 5-19 years-of-age. The incidence of SCD in youth in Michigan (USA) and nationwide is higher in racial/ethnic minorities and in certain geographic areas. School cardiac emergency response plans (CERPs) increase survival after cardiac arrest. However, school cardiac emergency preparedness remains variable. Studying population-level factors associated with school cardiac emergency preparedness and incidence of SCD in the young may improve understanding of disparities in the incidence of SCD.
Hypothesis/ProblemThe objective of this pilot study was to determine the association of elements of high school cardiac emergency preparedness, including Automated External Defibrillator (AED) distribution and the presence of CERPs with county sociodemographic characteristics and county incidence of SCD in the young.
MethodsSurveys were sent to representatives from all public high schools in 30 randomly selected Michigan counties. Counties with greater than 50% response rate were included (n=19). Association of county-level sociodemographic characteristics with incidence of SCD in the young and existence of CERPs were evaluated using Spearman correlation coefficient.
ResultsFactors related to the presence of AEDs were similar across counties. Schools in counties of lower socioeconomic status (SES; lower-median income, lower per capita income, and higher population below poverty level) were less likely to have a CERP than those with higher SES (all P<.01). Lack of a CERP was associated with a higher incidence of SCD in youth (r=-0.71; P=.001). Overall incidence of SCD in youth was higher in lower SES counties (r=-0.62 in median income and r=0.51 in population below poverty level; both P<.05).
ConclusionCounty SES is associated with the presence of CERPs in schools, suggesting a link between school cardiac emergency preparedness and county financial resources. Additionally, counties of lower SES demonstrated higher incidence of SCD in the young. Statewide and national studies are required to further explore the factors relating to geographic and socioeconomic differences in cardiac emergency preparedness and the incidence of SCD in the young.

During 1990 we surveyed the southern sky using a multi-beam receiver at frequencies of 4850 and 843 MHz. The half-power beamwidths were 4 and 25 arcmin respectively. The finished surveys cover the declination range between +10 and −90 degrees declination, essentially complete in right ascension, an area of 7.30 steradians. Preliminary analysis of the 4850 MHz data indicates that we will achieve a five sigma flux density limit of about 30 mJy. We estimate that we will find between 80 000 and 90 000 new sources above this limit. This is a revised version of the paper presented at the Regional Meeting by the first four authors; the surveys now have been completed.

INVERTEBRATE and micro-fossil collections vary in size, scope, degree of documentation, quality of curation, purpose, usage, and security. This chapter introduces the main categories of fossil collections and curatorial attention, and documents the sources and uses of invertebrate paleontological materials. The term ‘permanent collection’ is used to describe collections housed in professional collections-care institutions that provide long-term commitment to collection security and curation. Invertebrate fossils include the hardparts (spicules, shells, etc., other body fossils [e.g., impressions, casts, and molds]), tracks, trails, and burrows attributed to invertebrates, and organic molecules. Microfossils, included here for convenience only, include the same kinds of remains of prokaryotes, protists, and tiny invertebrates. This book is the product of an National Science Foundation funded workshop organized to address specific concerns about curatorial practices in invertebrate paleontology. For this reason the focus of this chapter is on invertebrate fossils. Nevertheless, the concepts and uses of collections described below apply directly to paleobotanic specimens, and to most vertebrate fossils.

The excavations of the cemetery groups at Balneaves, Loanleven and Park of Tongland facilitate an examination of many aspects of Bronze Age burial practices in Scotland. They are notable as much for the differences in burial ritual they imply as for the very narrow chronological period in which they were used. The three sites produced a total of seventeen 14C dates, two of which are aberrant, with means of the remaining fifteen falling within a period of 250 years (3370–3610 bp in radiocarbon years). The excavations were sponsored by Historic Scotland (formerly Historic Buildings and Monuments, Scotland).
At Balneaves, a penannular ditch enclosed sixteen features, including a group of seven pits with cremation burials, four of which were associated with a distinctive assemblage of collared urns. The cremated bone was well preserved. At least one large standing stone had been erected on the site, and this was buried in the medieval period.
At Loanleven, only a segment of the enclosing ring-ditch survived, within which were four cists, two containing inhumations and two cremations, one of the latter (Cist 2) associated with a fragment of a food vessel. A decorated slab, in so-called ‘Passage Grave Style’, was recovered from Cist 1, and the same cist produced palynological evidence for grave furnishings in the form of a mat of plant material which probably underlay the body. 14C dates give a terminus ante quem of 3620±50 bp (GU–2543) for the re-use of the decorated slab, and a terminus post quem of 3410±50 bp (GU–2542) for the food vessel grave.
Park of Tongland, regarded as a Four-Poster stone circle, was excavated after the fall of a standing stone. It was shown to be of multi-period construction, consisting of a cairn which overlay seven pits containing fragmentary cremation burials, two associated with collared urns. The standing stones may not all have been erect at the same time. A series of 14C dates fell within the range of 1480–1530 bc.

This 5-yr program which began in 1987 is to establish a link between the radio and optical reference frames, using about 400 extragalactic sources which are compact and flat spectrum in the radio and which are observable in the optical. An overview of the program is presented at this meeting by Johnston et al. Various specific aspects of it are also discussed in Ma et al., McCarthy et al. and Reynolds et al.
The observations have been continuing in both hemispheres and in both the radio and the optical. We have observed 348 sources with VLBI. There is at least one astrograph plate available for 369 sources and at least one prime focus plate available for 138 sources. Altogether there are 450 sources with some data.

In 1987 we began a 5-year program to establish a reference system of at least 400 extragalactic sources which are compact and flat spectrum in the radio and which also display optical emission. This reference frame is to be global with about one source per 100 sq deg (Johnston, et al., 1988). The program incorporates some data which had been obtained previously for other purposes. Altogether, in one or another aspect of the program, 489 sources have been considered so far.

A pilot study was conducted to investigate the possibility of using goats to manipulate the amount and composition of indigenous and improved vegetation on hill land in the west of Scotland.
Two vegetationally similar plots, each of approximately 0·6 ha, were used. Approximately 0·45 of each plot comprised sown ryegrass-clover pasture, the remainder being indigenous vegetation (principally Calluna vulgaris, Eriophorum and Tricophorum spp. with some Deschampsia, Molinia and Carex spp.). One plot was stocked with 14 yearling Anglo-Nubian goats and the other with seven mature Blackface sheep, the total weight of livestock on the two plots being the same (500 kg).
On the reseeded areas the proportions (± s.e. of difference) of ryegrass grazed by sheep and goats after 2, 5 and 8 weeks were 0·65 and 0·11 (0·075), 0·68 and 0·42 (0·112), and 0·77 and 0·58 (0·149), respectively; corresponding values for proportional clover cover were 016 and 0·45 (0·071), 0·16 and 0·38 (0·070), and 0·10 and 0·35 (0·070), respectively. The goats also actively grazed clumps of Juncus spp. and invading indigenous species which were not eaten by sheep.
On the indigenous areas the sheep grazed a higher proportion of Calluna than did goats (0·08 and 0·05) but grazed less E. vaginatum (0·07 and 0·13), E. angustifolium (0·04 and 0·11), and other indigenous species (0·21 and 0·36), respectively. The degree of utilization of grazed indigenous species by goats was also greater than that by sheep for all species except Calluna.
The results suggest that goats may have a use in some sheep production systems as an aid to the management of the varied plant communities of hill land, and particularly in the maintenance and further improvement of reseeded pastures.

An experiment was conducted with 84 suckling Scottish Blackface twin lambs on an improved hill pasture with a history of cobalt deficiency and molybdenum/sulphur-induced copper deficiency. The dams of 13 pairs of twins were treated with 90 mg copper at parturition (Cue) and one member of each pair was given a cobalt bullet (Co + ). One member of each of a further 29 pairs was treated periodically with 5 to 15mg copper to maintain plasma copper concentrations >0·6mg/l (Cu+) while their siblings received no supplementary copper (Cu). Fourteen of these pairs also received a cobalt bullet (Co + ). Lambs not treated with cobalt are designated Co−.
The Cue treatment increased milk copper concentrations, but only for a short time, and resulted in transitory increases in lamb plasma copper concentrations and rate of live-weight gain. At the end of the grazing phase, at approximately 20 weeks of age, Cu+ lambs had gained 0-28 kg more weight than Cue lambs and 158 kg more than Cue lambs, and had higher liver copper concentrations. Cu+ and Cue lambs had heavier and fatter empty bodies and carcasses than Cu− lambs. The cobalt treatment produced no effects at this stage.
Fifty-four of the lambs were housed and given dried grass pellets ad libitum. After 83 days liver copper concentrations were higher in Co− than Co+ lambs, and in Cu+ than in Cu− and Cue lambs. The copper treatments had no effect on rate or efficiency of live-weight gain, but Co− lambs gained weight more quickly and more efficiently than Co+ lambs.
