Native languages of the Americas whose predicate and clause structure reflect nominal hierarchies show an interesting range of structural diversity not only with respect to morphological makeup of their predicates and arguments but also with respect to the factors governing obviation status. The present article maps part of such diversity. The sample surveyed here includes languages with some sort of nonlocal (third person acting on third person) direction-marking system.

BACKGROUND AND PURPOSE The posterior circulation Acute Stroke Prognosis Early CT Score (pc-APECTS) applied to CT angiography source images (CTA-SI) predicts the functional outcome of patients in the Basilar Artery International Cooperation Study (BASICS). We assessed the diagnostic and prognostic impact of pc-ASPECTS applied to perfusion CT (CTP) in the BASICS registry population. METHODS We applied pc-ASPECTS to CTA-SI and cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT) parameter maps of BASICS patients with CTA and CTP studies performed. Hypoattenuation on CTA-SI, relative reduction in CBV or CBF, or relative increase in MTT were rated as abnormal. RESULTS CTA and CTP were available in 27/592 BASICS patients (4.6%). The proportion of patients with any perfusion abnormality was highest for MTT (93%; 95% confidence interval [CI], 76%-99%), compared with 78% (58%-91%) for CTA-SI and CBF, and 46% (27%-67%) for CBV (P < .001). All 3 patients with a CBV pc-ASPECTS < 8 compared to 6/23 patients with a CBV pc-ASPECTS ≥ 8 had died at 1 month (RR 3.8; 95% CI, 1.9-7.6). CONCLUSION CTP was performed in a minority of the BASICS registry population. Perfusion disturbances in the posterior circulation were most pronounced on MTT parameter maps. CBV pc-ASPECTS < 8 may indicate patients with high case fatality.

Die Mehrzahl PC-gestützter Trainingsprogramme erhebt den Anspruch einer theoriegeleiteten Konzeption und weckt entsprechend hohe Erwartungen. Wissenschaftliche Wirksamkeitsnachweise existieren nur für wenige Verfahren. Der Arbeitskreis Aufmerksamkeit & Gedächtnis der GNP präsentiert hier die Struktur einer Programmrezension, die eine übersichtliche Zusammenfassung und transparente Bewertung von Trainingsprogrammen unter Bezug auf insgesamt 20 neuropsychologische, technische und pragmatische Kriterien erlaubt. Schließlich beschreiben wir den Aufbau eines Manuals, das für alle Kriterien die qualitäts-bestimmenden Programmeigenschaften spezifiziert und durch die Erstellung einer Rezension führt; das komplette Manual ist in diesem Heft abgedruckt. Die mit dieser Zeitschrift begonnene Veröffentlichung von Beispielrezensionen wird in loser Folge fortgesetzt.
