The exploration of health seeking behaviour of clients presenting with minor ailments attending community health centres in Khayelitsha (Michael Mapongwana, Site B) and Phillipi (Inzame Zabantu, Mzamomhle)
No full textIncludes bibliographical references.CHCs in Khayelitsha and Phillipi are overcrowded and overburdened with clients who tend to present with minor ailments. The problem of overcrowding of the CHCs with such clients poses a problem to the health professional as they do not have sufficient time to manage clients with more serious ailments and to educate those with minor health ailments. This problem of overcrowding of CHCs in Khayelitsha and Phillipi with clients presenting with minor health ailments was brough to a community health forum meeting that constituted the management of CHCs, clinical facilitators from the University of Cape Town (UCT) and elderly persons from Khayelitsha and Phillipi in 2001. At this meeting questions were raised regarding the health seeking behaviour of the clients that are presenting with minor health ailments and overcrowding the CHCs
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
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
Chopin's piano work with focus on Sonate b flat minor
No full textThe author in his work focuses on the Polish music composer fryderyk Chopin and his Sonate b flat minor op. 35 for piano. Work contains a composer biography in connection with his work, characteristic of Chopin´s personality, a brief chapter about his piano work and mainly a chapter about Sonate b flat minor, which is divided to some sub chapters. The author mostly focuses on the interpretative problems of this composition, where hederives benefit from his own experience. Relatively large is also the sub chapter "Form analysis of the Sonate b flat minor". One of the main objectives of this work is to help beginning interpreters of Chopin´s Sonate b flat minor and this work might be useful also for all musicians who are interested in Chopin´s piano work
Evaluation of minor pathogen intramammary infection, susceptibility parameters, and somatic cell counts on the development of new intramammary infections with major mastitis pathogens
No full textMajor mastitis pathogens such as Staphylococcus aureus, Streptococcus uberis, Streptococcus dysgalactiae, and coliforms are usually considered more virulent and damaging to the udder than minor mastitis pathogens such as Corynebacterium spp. and coagulase-negative staphylococci (CNS). The current literature comprises several studies (n=38) detailing analyses with conflicting results as to whether intramammary infections (IMI) with the minor pathogens decrease, increase, or have no effect on the risk of a quarter acquiring a new IMI (NIMI) with a major pathogen. The Canadian Bovine Mastitis Research Network has a large mastitis database derived from a 2-yr data collection on a national cohort of dairy farms, and data from this initiative were used to further investigate the effect of IMI with minor pathogens on the acquisition of new major pathogen infections (defined as a culture-positive quarter sample in a quarter that had been free of that major pathogen in previous samples in the sampling period). Longitudinal milk samplings of clinically normal udders taken over several 6-wk periods as well as samples from cows pre-dry-off and postcalving were used to this end (n=80,397 quarter milk samples). The effects of CNS and Corynebacterium spp. on the major mastitis pathogens Staph. aureus, Strep. uberis, Strep. dysgalactiae, and coliform bacteria (Escherichia coli and Klebsiella spp.) were investigated using risk ratio analyses and multilevel logistic regression models. Quarter-, cow- and herd-level susceptibility parameters were also evaluated and were able to account for the increased susceptibility that exists within herds, cows and quarters, removing it from estimates for the effects of the minor pathogens. Increased quarter-level susceptibility was associated with increased risk of major pathogen NIMI for all pathogens except the coliforms. Increased somatic cell count was consistently associated with elevated risk of new major pathogen infections, but this was assumed to be a result of low sensitivity of bacteriology to diagnose major pathogen NIMI expediently and accurately. The presence of CNS in the sample 2 samplings before the occurrence of a NIMI increased the odds of experiencing a Staph. aureus NIMI 2.0 times, making the presence of CNS a risk factor for acquiring a Staph. aureus NIMI. Even with this extensive data set, power was insufficient to make a definitive statement about the effect of minor pathogen IMI on the acquisition of major pathogen NIMI. Definitively answering questions of this nature are likely to require an extremely large data set dedicated particularly to minor pathogen presence and NIMI with major pathogens
Phytotoxicity of Class B aqueous firefighting formulations, Tridol S 3 and 6% to Lemna minor
No full textPhytotoxicity of Class B aqueous firefighting concentrates, Tridol-S 3%, and Tridol-S 6% to Lemna minor were studied using the parameters such as the frond number, biomass production in terms of dry weight, chlorophyll content and proline accumulation. Decrease in fresh weight, dry weight, and chlorophyll pigments; increase in proline content suggested that both the firefighting concentrates are potentially toxic to L. minor. Relative growth rate (RGR) also showed a similar pattern of toxicity with the corresponding increase in test concentrations of both the compounds. The EC50 values show Tridol-S 3% was more toxic than Tridol-S 6% in terms of frond number and dry weight. From our findings, it is clear that L. minor is highly sensitive to the exposure of firefighting foams, and is suitable for its use as an indicator organism for assessing the aquatic toxicity of aqueous firefighting foams. This study clearly suggests that the migration of Tridol AFFF into aquatic environments is likely to have detrimental effects on the aquatic flora. To the best of our knowledge, this study constitutes the first report on the phytotoxicity of firefighting concentrates, Tridol-S 3% and Tridol-S 6% to Lemna minor L
Parallel Proportions, Numerical Structures and Harmonie in Bach's Autograph Score
No full textThe B-minor Mass has always represented a fascinating challenge to musical scholarship. Composed over the course of Johann Sebastian Bach's life, it is considered by many to be the composer's greatest and most complex work. The fourteen essays assembled in this volume originate from the International Symposium 'Understanding Bach's B-minor mass' at which scholars from eighteen countries gathered to debate the latest topics in the field. In revised and updated form, they comprise a thorough and systematic study of Bach's Opus Ultimum, including a wide range of discussions relating to the Mass's historical background and contexts, structure and proportion, sources and editions, and the reception of the work in the late eighteenth and early nineteenth centuries. In the light of important new developments in the study of the piece, this collection demonstrates the innovation and rigour for which Bach scholarship has become known.</p
