Association mapping for barley traits related to organic farming
No full textIn context of a larger project dealing with the traits of barley that are related to organic farming (BAR-OF), we performed an association mapping in order to dertermine the genetic loci linked with the respective traits. In two subsequent years (2002 and 2003), we used field results from 96 barley lines and varieties, partially overlapping between the years. The lines/varieties were grown on three Dansih locations (Flakkebjerg, Foulum and Jyndevad). For Foulum and Flakkebjerg, we observed both fields grown under organic and conventional regime; for Jyndevad only fields cultivated under organic conditions were ecploited. Neither in the organic nor in the conventional fields; diseases were controlled chemically. In the resulting five environments per year, deseases (powdery mildew, leaf rust, scald and net blotch), morphology related traits (stem lengh, ear braking, stem breaking and lodging), development related traits (time of heading and time of ripening) and yield related traits (kernel yiedl, kernel weight, kernel density, kernel size, starch and protein content) were observed. for the marker study, we used 65 polymorphic microsatellite markers distributed over all seven barley chromosomes. In the association analysis we applied a GLM analysis in the software TASSE and accepted only association with an error probability lower than 10-5. Beside for ear breaking, we found significant associations for each of the traits observed and always on more than one chromosome. The major part of the associations differed from 2002 to 2003. For the disease resistances and the kernel weight, we observed a relative high stability of the associated marker loci over the years, even so the barley lines on the field experiments differed partially from one year to the other. Surprisingly, we fond the best stability of association comparing the two years for the trait "kernel yield". Further analysis, especially in relation to G x E interaction and the influence of organic/conventional conditions will be published in an upcoming paper
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
Perspectivas de transcender na educação no trabalho: tendências da enfermagem latino-americana
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde. Programa de Pós-Graduação em Enfermagem.O objetivo deste estudo está em evidenciar as tendências de educação no trabalho na América Latina as quais estão sendo veiculadas nos periódicos de enfermagem, analisando-as crítica e reflexivamente. Na revisão da literatura utilizaram-se autores de diferentes áreas de atuação, em especial da enfermagem. A construção do referencial filosófico teve como base a Teoria Problematizadora de Paulo Freire e a Práxis de Adolfo Sánchez Vázquez, secundados por outros autores. Metodologicamente este estudo pode ser classificado como qualitativo, exploratório, com pesquisa documental. Para organizar os dados da pesquisa foi construído um software que permitiu o armazenamento de dados como: origem dos artigos publicados; formação, titulação e área de atuação dos autores; as revistas foram catalogadas pela denominação, número volume, ISSN, ano, mês e cidade em que foram publicadas. A pesquisa envolveu 18 periódicos que disponibilizam textos integrais e livres, com a revisão de 299 exemplares, 3310 de resumos e palavras chaves, dos quais foram retirados 70 artigos completos sobre a educação no trabalho de 07 diferentes países latino-americanos. Na contextualização do cenário do estudo evidenciaram-se pontos críticos na enfermagem, tais como: diversidade de formação, insuficiência quantitativa e qualitativa de pessoal, migração de enfermeiras, concentração em grandes centros urbanos. Estratégias de resolução a serem implementadas a médio e longo prazo são preconizadas na Agenda de Saúde para América-OPAS/OMS, associações profissionais e de classe, fundações filantrópicas, entre outras. No tratamento dos dados obtidos construíram-se seis categorias e as subseqüentes estruturas de resposta: as tendências de educação no trabalho, educação no trabalho e níveis de práxis, a educação no processo de trabalho na enfermagem, a educação no trabalho e a relação entre cuidar e educar, a educação no trabalho e a construção do conhecimento e a educação no trabalho na perspectiva do empoderamento dos sujeitos. Evidencia-se a possibilidade de transcendência em países como Brasil, Chile, Colômbia e México, em razão da amplitude das propostas de educação, embasamento em teorias educativas, formação, capacitação e titulação de recursos humanos, a articulação entre docência/serviços e as políticas de saúde. Na Argentina as ações educativas estão mais para a conservação em moldes tecnicistas. Em Cuba, a ênfase na obtenção dos resultados reforçam o tecnicismo com viés ideológico, enquanto que no Paraguai as propostas de educação no trabalho são praticamente incipientes. A construção desta pesquisa mostra que as possibilidades de transcendência estão na aproximação de teoria e prática, estruturação dos serviços, com propostas de educação no trabalho que permitam o empoderamento dos sujeitos. The objective of this study is to show the tendencies of education at work in Latin America which are linked with the Nursing periods, analyzing the critics and reflexive. In the revision of the authors literature different areas of actuation were used, especially nursing. The construction of philosophical references has as a base the Problematical Theory of Paulo Freire and the customs of Adolfo Sanchez Vasquez, supported by other authors. Methodologically this study can be classified as qualitative, exploratory, with documental study. To organize the data of the study a software was constructed that permits the storage of data like: the origin of articles published; formation, title and area of actuation of the authors; the magazines were cataloged by denomination, volume number, ISSN, year, month and the city in which they were published. The study involves 18 periods that permits a availability of integral texts and are free, with the revision of 299 examples, 3310 of abstracts and keywords, out of which 70 complete articles on education at work of 07 different Latin # Americans countries. In the contextualization of study scenario we can see the critical points of nursing, like: the diversity of formation, insufficient quantitative and qualitative of people, migration of nurses, concentration in grand urban centers. The strategy and resolution that are to be implemented in medium and long period are pre agenda in the Health Agenda for America # OPAS / OMS, professionals associations and the class, philanthropic foundations, among others. In the treatment of data obtained six categories are constructed and next structures of reply: the tendency of education at work, education at work and the level of the practice, education in the work process in nursing, education at work is the relation between care and educate, education at work is the construction of knowledge and education at work in the perspective of empowerment of people. As shown the possibility of transcending of countries like Brazil, Chile, Colombia and Mexico, in the light of the amplitude of the education proposal, based on educative theories, formation, capacity and titled of human resources, the articulation between docent/services and the health political. In Argentina the educative actions are more of conservation in technical model. In Cuba, the emphasis in obtaining of results reforces the technical with ideological line while in Paraguai the proposals of education at work are practicalment incipient. The construction of this study shows the possibility of transcendences are in the approximation of theory and practical, construction of services, with proposals of education at work that permits the empowerment of people
Exposure to Ultraviolet (UV-C) Radiation Increases Germination Rate of Maize (<i>Zea maize</i> L.) and Sugar Beet (<i>Beta vulgaris</i>) Seeds
No full textThis study investigated the effect of ultraviolet (UV-C) radiation on the germination percentage, germination rate, radicle length, and plumule length of maize and sugar beet seeds. The experiment was implemented in six replicates of 30 seeds per replicate and in sterilized petri dishes under laboratory conditions. Treatments included UV-C (254 nm) radiation exposure durations of 0 min (control), 30 min, 2 h, 4 h, 8 h, and 12 h. The UV-C radiation treatments did not significantly affect the germination percentage of the seeds (p < 0.05). However, the seeds germination rate was significantly affected by the UV-C radiation treatments. The treatments of 8 h and 12 h exposure duration led to the highest seed germination rates in maize and sugar beet, respectively. Lowest seed germination rates belonged to the controls. The radicle length of maize seeds was significantly affected by the UV-C radiation treatments, but the treatments did not significantly affect the radicle length of sugar beet seeds. The 12 h exposure to UV-C radiation treatment resulted in the largest radicle in maize, which was 2.08 cm larger than the radicle of the control seeds. The UV-C radiation treatments had a statistically significant effect on the plumule length of maize and sugar beet seeds. The treatment 8 h UV-C exposure duration led to the largest plumule in maize and sugar beet, which were 0.32 cm and 0.83 cm larger than the plumule of the control seeds, respectively. Breaking down the seed coat and increasing the temperature by UV-C radiation are potential reasons for the observed positive effects
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
Astrotourism for development in Namibia: dark sky education and heritage
No full textNamibia is world-renowned for its incredibly dark skies by the astronomy community, and yet, the country is not well known by tourists and travellers as a dark sky destination. Forged by a collaboration between the Universities of Oxford and Namibia, together we are using astronomy as a means for capacity-building via educating tour guides and promoting astrotourism to relevant stakeholders. Astrotourism offers many benefits: heritage is preserved and celebrated; tour guides learn about astronomy and complement their earnings; meanwhile tourists engage in awe-inspiring activities while learning about topics like indigenous astronomy and light pollution. In order to implement astrotourism sustainably, we have been working from both a bottom-up and top-down approach. The main barriers include access to training and astrotourism knowledge: (1) there exists a tour guide qualification in astronomy but this is currently unobtainable without the means and materials to study the topic. To bridge this barrier we are developing a course for tour guides, for which we are exploring both online and offline formats. Crucially, the content will not focus on western astronomy, but will include topics on indigenous astronomy in Southern Africa and light pollution, and will be made adaptable for other countries. (2) Namibia is already highly regarded as a country for its ecotourism activities. Thus, we are working with the Ministry of Environment, Forestry, and Tourism, and relevant tourism associations, to help establish Namibia as a country at the forefront of astrotourism. This talk will explore the successes and challenges that we have encountered, whilst providing context internationally, so that dark sky education and heritage can be beneficial on global scales...
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
