Evaluation of shrimp culturing and hatcheries sites in Hormozgan province
Get PDFThis project was performed to evaluate the qualitative and quantitative operation of hatcheries and shrimp culture Sites in Hormozgan province during years 2004-2006. All the active hatcheries including one hatchery located in Bandar-e-Jask, Three hatcheries in Bandar-e-Kohestak, one hatchery in Bandar-e-kolahi and two hatcheries in Qeshm island also three shrimp culture sites including Tiab-e-Shomali, Tiab-e-Jonubi and sayeh khosh were surveyed. The Information about scientific and technical persons, employments, productions, important problems and also situation of costs and net were recorded in special forms. Results were analyzed by descriptive statistics. Results revealed that about 50% of the hatcheries located in Hormozgan province are closed through the different problems such as, failure of customer, failure of a distinct plan for post larvae producing, high cost of producing parameters and so on. Results also revealed that only 7.1% of farms located in sayeh khosh area, about 40.2 % of farms located in Tiab-e-Shomali and 62 % of farms located in Tiab-e-Jonubi areas are active. The two later areas have established about ten years ago. The most problems of most farm in Hormozgan province are the failure of sufficient knowledge of farms managers, high cost and low quality of shrimp foods manufactured by huge factories and low cost of cultured shrimps. Final, it can be said that problems of hatcheries are depended to shrimp farms problems. If problems of farms be did, problems of hatcheries will be did

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
Factors associated with preterm labor in Hormozgan province in 2013
No full textIntroduction: Preterm labor is the main cause of infants' death, and the main reason for undesirable
consequences of pregnancy which still occur in some births, despite all of the interventions in this regard. The
aim of this study was to evaluate every preterm birth and determine its maternal risk factors in Hormozgan
province in 2013.
Methods: This case-control study was conducted in 2013 on the health and hospital records of 735 pregnant
mothers with preterm labor (20-37 weeks) which were located in Bandar Abbas in southeast Iran. The sampling
method would be multi-stage cluster sampling. The data collecting tool was a valid questionnaire by the Iran
Ministry of Health and Medical Education, which included 5 components (demographic information, checking
the current pregnancy of the mother, the maternal factors related to preterm labor in the previous pregnancy,
evaluating the fetal factors associated with preterm labor in the current pregnancy and other additional
information related to the factors associated with prematurity). Data were analyzed using descriptive statistics,
regression and Chi-square tests
Results: The prevalence of preterm labor in Hormozgan province in 2013 was 5.5%. In our study and among the
effective factors on preterm labor, revealed genital-urinary tract infections during pregnancy were (35.8%),
PROM (30.3%), history of abortion (19.9%) and unplanned pregnancy (18.1%) in between pregnant women with
preterm labor. Our study showed that most mothers had delivered in 33 to 37 weeks among the mothers who had
preterm labor in 2013 (75%) and the statistic of very preterm labor (less than 32 weeks) in Hormozgan was 5%.
Conclusion: Identification of the prevalence and associated factors with preterm labor can reduce the mortality
rate and infants' complications of it in addition to help find a way to prevent this problem
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Get PDFWe 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
