Genetic polymorphism of the 17th exon at porcine RYR1 locus: a new variant in a local Portuguese pig breed demonstrated by SSCP analysis
No full textUntil 1991, malignant hyperthermia represented a major and important economic loss in modern pork production. It is a recessive autosomal disorder with variable expression that was. not known to occur in the local pig breeds from Portugal, Alentejano and Bisaro, prior to outcrossing with commercial breeds. In swine, this disorder is due to a mutation in exon 17 of the ryanodine receptor 1 (RYR1) gene, detectable through the analysis of a restriction fragment length polymorphism. We used this technique to distinguish between resistant (NN), carrier (Nn) and susceptible (nn) genotypes, with the aim of excluding carriers from the breeding programme. We further developed a rapid screening technique on the basis of SSCP (single-strand conformation polymorphism). Fifteen heterozygous (Nn) individuals were found in our sample of 48 individuals from Bisaro breed using both techniques. The absence of homozygous susceptible pigs su ts that the introduction of this allele into Bisaro breed has been recent. A genetically controlled breeding programme on the basis of our findings should help to secure the future of Bisaro pigs Of which few individuals are known to exist. To date, only one mutation was found in the 5 ' end of exon 17 of the porcine RYR1 gene. Here we present the frequencies of this mutation and describe a new mutation detected in the Alentejano breed. PCR-SSCP analysis followed by automatic sequencing allowed the detection of this rare transition (C --> T) at nucleotide 1851 of exon 17

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Arquitetura, espaços e atividades criativas: A Casa da Cultura de Beja
No full textInspirada em valores inovadores (sociais e culturais), o propósito da criação da Casa da Cultura da Juventude de Beja, pelo Arquiteto Hestnes Ferreira,foi proporcionar uma cultura mais democrática assente num modelo comunitário e de participação ativa. A investigação resulta da análise deste edifício, demonstrando premissas de valorização do património edificado, que possam favorecer a economia criativa em cidades de pequena dimensão ou com particularidades rurais. O artigo conceptualiza a criatividade e a economia criativa enquanto estratégias de desenvolvimento da sustentabilidade territorial; a Arquitetura, enquanto subsetor das Indústrias Culturais e Criativas, exprimindo as dinâmicas sociais e culturais de um território, como enfoque na cidade de Beja. Por fim, propomos perspectivas futuras que articulem a ação dos atores culturais com as comunidades locais.info:eu-repo/semantics/publishedVersio

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
