Occurrence of gastrointestinal helminthes in commercial and free-range chickens in Gaza Strip, Palestine
Full text linkThe present study compared the prevalence of helminthes parasites in two chicken breeds in Gaza strip, the commercial and the free-range indigenous. Gastrointestinal tracts of 100 commercial growers and 90 free-range indigenous chickens collected from Gaza city were examined for helminthes during 2007–2008. The commercial chickens were free of helminthes while the indigenous chickens were encountered five helminthes, three nematodes and two cestodes .The nematodes identified were Ascaridia galli (75.6%), Heterakis gallinarum (68.9%) and Capillaria spp. (2.2%). The cestodes were, Raillietina echinobothrida (57.8%) and Choanotaenia infundibulum (26.7%). No trematode was found. The intensity of parasites was low except for H. gallinarum. It was concluded that the indigenous chickens were infected with some types of cestodes and nematodes in Gaza markets. Sanitations and public health should be of concerned for both health authorities, consumers and farmers owners
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
Association between distance of sewage plant and prevalence of intestinal parasites among children of Beit-lahia, Gaza Strip, Palestine.
No full textA cross sectional study was conducted during 2002-2004 to determine the association between the distance of sewage palnts as a sanitation conditionor factor and the prevalence of different types of intestinal parasites in Beit- Lahia, Gaza Strip Palestine. From Beit- Lahia 2000 individuals 2 to 15 years old were participated in the study. One stool sample was examined for the presence of ova and / or larvae of helminthes and protozoan parasites for each individuals. The parasitological methodsused in this studywhere the direct smear microscopy and formal- ether sedimentation technique. The present study showed that 700 individuals were infected with different types of intestinal parasites with a prevalence of 35%. the following parasites were detected. Ascaris lumbricoides ( 18.6% , Enterobius vermicularis ( 3.2% . Giardia lamblia ( 3.6% , Strongyloides stercoralis ( 0.9% , Entamoeba histolytica/dispar ( 2.6% , Hymenolepis nana ( 1.7% , mixed infection ( 4.4% , in addition to one, case of Trichuris trichura. It was found that 29.2% of infected persons were residing with a distance 1200 meters with a significant diffrernce ( p-0.003 . These unexpected results were attributed to the fact that most children prefere to play and move in more far and opened area and this is a true culture for children in our community, and the matter need more investigation. In both children either residing close or at different distances from sewage plant they were exposed to the parasitic infection. It is recmmended to remove these sewage plants and pools from the area of Bet-lahia to protect peoples

Full text linkVariations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
