Decline of the flora in Danish arable fields
No full textSurveys of the weed flora in Danish arable fields were conducted during 1967-70 and 1987-89. Frequencies of 67 common weed species in spring barley, spring rape, winter rye, winter wheat and grass ley were compared. The comparison showed that the occurrence of common weed species has generally decreased during the last 20 years. The frequency of some species such as Anagallis arvensis, Arenaria serpyllifolia, Atriplex patula, Cerastium caespitosum [C. fontanum], Galium aparine, Plantago major and Silene noctiflora has decreased markedly, possibly because of intensive chemical weed control. The dominating weed species in the 1987-89 survey were largely the same as in the 1967-70 survey, namely Capsella bursa-pastoris, Chenopodium album, Elymus repens, Myosotis arvensis, Poa annua, Polygonum aviculare, P. convolvulus [Fallopia convolvulus], P. persicaria, Stellaria media, Taraxacum, Veronica arvensis, V. persica and Viola arvensis. Some species occurred more frequently in 1987-89 than in 1967-70, but only Stellaria media increased significantly and only in grass ley..RE: 44 ref.; SC: CA; CR; PE; 0W; 6TSource type: Electronic(1) http://upei-resolver.asin-risa.ca?sid=SP:CABI&id=pmid:&id=&issn=0021-8901&isbn=&volume=33&issue=3&spage=619&pages=619-626&date=1996&title=Journal%20of%20Applied%20Ecology&atitle=Decline%20of%20the%20flora%20in%20Danish%20arable%20fields.&aulast=Andreasen&pid=%3Cauthor%3EAndreasen%2c%20C%3bStryhn%2c%20H%3bStreibig%2c%20J%20C%3C%2Fauthor%3E%3CAN%3E19962302237%3C%2FAN%3E%3CDT%3EJournal%20article%3C%2FDT%3
California Poll: 8901 -- January 23-31, 1989
No full textThe Field Poll, established in 1945 as The California Poll by Mervin Field, has operated continuously as an independent, non-partisan, media-sponsored public opinion news service. Each year the Field Polls cover a wide range of political and social topics examining California public opinion. Continuing measures are made of voter support for leading political figures vying for major state and federal offices, job ratings of important political figures and reactions to significant political events. Voter awareness, understanding and predispositions of major campaign issues and salient statewide ballot propositions are also tracked over time. For poll 8901 N=1007
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
