Keep at bay! - Abnormal personal space regulation as marker of paranoia in schizophrenia.

BACKGROUND During threat, interpersonal distance is deliberately increased. Personal space regulation is related to amygdala function and altered in schizophrenia, but it remains unknown whether it is particularly associated with paranoid threat. METHODS We compared performance in two tests on personal space between 64 patients with schizophrenia spectrum disorders and 24 matched controls. Patients were stratified in those with paranoid threat, neutral affect or paranoid experience of power. In the stop-distance paradigm, participants indicated the minimum tolerable interpersonal distance. In the fixed-distance paradigm, they indicated the level of comfort at fixed interpersonal distances. RESULTS Paranoid threat increased interpersonal distance two-fold in the stop-distance paradigm, and reduced comfort ratings in the fixed-distance paradigm. In contrast, patients experiencing paranoid power had high comfort ratings at any distance. Patients with neutral affect did not differ from controls in the stop-distance paradigm. Differences between groups remained when controlling for gender and positive symptom severity. Among schizophrenia patients, the stop-distance paradigm detected paranoid threat with 93% sensitivity and 83% specificity. CONCLUSIONS Personal space regulation is not generally altered in schizophrenia. However, state paranoid experience has distinct contributions to personal space regulation. Subjects experiencing current paranoid threat share increased safety-seeking behavior.

Wissenstransfer, Experten und ihre Handlungsspielräume am Instituto de Nutrición de Centroamérica y Panamá (INCAP), 1961-1982

In the history of development there has been a tendency to attribute developmental initiatives to coordinating centres in the global north and view countries in the south as recipients, a phenomenon that continues to the present day. The Central American Nutrition Institute (INCAP) is by contrast an example of a regional institution that not only generated a considerable body of knowledge concerning the nutritional state of the region and policy proposals but also advocated an alternative development model emphasizing local resources. Although INCAP enjoyed some success in disseminating a number of its ideas through international organisations, the implementation of its vision was ultimately hampered by the unstable political situation prevailing in Central America in the time period analyzed in this article.

Nighttime Catches of Fishes in a Tidal Cove in Montsweag Bay Near Wiscasset Maine

Summer nighttime abundance and localized distribution of fishes in a tidal cove were studied by beach seining for comparison with a previous daytime study. American eels were relatively abundant at night and absent during the day. Alewife, blueback herring, and Atlantic silver-side were more abundant in the cove at night. Although mummichog numbers were greatly reduced at night, they remained an important constituent of the night fauna. Lesser components of the night fauna included Atlantic herring, Atlantic tomcod, smooth flounder, winter flounder, and rainbow smelt.
