The Forgotten Side of Partisanship: Negative Party Identification in Four Anglo-American Democracies

Early studies of electoral behavior proposed that party identification could be negative as well as positive. Over time, though, the concept became mostly understood as a positive construct. The few studies that took negative identification into account tended to portray it as a marginal factor that went “hand-in-hand” with positive preferences. Recent scholarship in psychology reaffirms, however, that negative evaluations are not simply the bipolar opposite of positive ones. This article considers negative party identification from this standpoint, and evaluates its impact in recent national elections in Australia, Canada, New Zealand, and the United States. Our findings highlight the autonomous power of negative partisanship. They indicate as well that ideology has an influence on both positive and negative partisan identification

Intraspecific Variation of the Aquatic Fungus Articulospora tetracladia: An Ubiquitous Perspective

The worldwide-distributed aquatic fungus Articulospora tetracladia Ingold is a dominant sporulating species in streams of the Northwest Iberian Peninsula. To elucidate the genetic diversity of A. tetracladia, we analyzed isolates collected from various types of plant litter or foam in streams from North and Central Portugal and North Spain, between 2000 and 2010. Genetic diversity of these fungal populations was assessed by denaturing gradient gel electrophoresis (DGGE) fingerprints and by using ITS1-5.8S-ITS2 barcodes. Moreover, ITS1-5.8S-ITS2 barcodes of A. tetracladia reported in other parts of the world (Central Europe, United Kingdom, Canada, Japan and Malaysia) were retrieved from the National Center for Biotechnology (NCBI) and the National Institute of Technology and Evaluation Biological Resource Center (NBRC) to probe into genetic diversity of A. tetracladia. PCR-DGGE of ITS2 region of 50 Iberian fungal isolates distinguished eight operational taxonomic units (OTUs), which were similar to those obtained from neighboring trees based on ITS2 gene sequences. On the other hand, ITS1-5.8S-ITS2 barcodes of 68 fungal isolates yielded nine OTUs, but five fungal isolates were not assigned to any of these OTUs. Molecular diversity was highest for OTU-8, which included only European isolates. Two haplotypes were observed within OTU-8 and OTU-9, while only one haplotype was found within each of the remaining OTUs. Malaysia did not share haplotypes with other countries. Overall results indicate that, apart from the Malaysian genotypes, A. tetracladia genotypes were geographically widespread irrespective of sampling time, sites or substrates. Furthermore, PCR-DGGE appeared to be a rapid tool for assessing intraspecific diversity of aquatic hyphomycetes

Referendums and referendum campaigns

The purpose of this entry is to explain what a referendum is, why it is held, as well as to discuss the notion of a referendum campaign. The entry then turns its attention to the 2020 New Zealand referendums on cannabis and End of Life Choice, which are offered as exemplars to showcase the unique neutral ‘signposting campaign’ approach utilised by the Government
