Isolation and characterization of mesophilic bacteria from rhizosphere of plant rice (Oryza sativa) from Lodhran, Pakistan
No full textThe present study demonstrated isolation and characterization of 48 bacterial strains
(ABOs01-ABOs48) from rhizosphere of rice plant (Oryza sativa) of Rind Jada (Kahror Pacca),
Punjab, Pakistan. Morphological studies including colony color, bacterial shape and gram
staining were performed and colonies were observed to be either orange yellow, light yellow,
pink, greenish yellow, white, or off-white in appearance. Gram staining showed that out of 48
isolates, 38 were gram positive and 10 were gram negative. Various Biochemical tests were
performed to identify these strains; the results were used to identify these strains at the species
levels. These strains belongs to the following species Erwinia stewartii (13), Klebsiella terrigena
(9), Klebsiella pneumonia susp. Ozaene (8), Serratia plymuthica (6), Yersinia (5), Escherichia
blattae (5), 1 Edwardsiella ictaluri (1), and Obesumbacterium proteus (1). Additionally,
amylase test showed that 39 strains were positive while 9 were negative. Conversely, all strains
were negative for cellulase production. Finally, Antibiotics resistance showed 23 isolates were
sensitive vs 25 resistant to ampicillin and 4 isolates were resistant vs 44 sensitive to penicillin.
These findings suggested a great microbial diversity in rice plant rhizosphere which demands
more investigations for agricultural and industrial purposes
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

When to regulate airports: A simple rule
No full textLanding fees at airports are regulated almost all over the world since airports are assumed to abuse their market power. We find that monopolistic airports have an incentive to restrain landing fees when they generate additional non-aviation revenues and that the optimal landing fee decreases in the degree of complementarity of aviation and non-aviation. Furthermore, we show that monopolistic airports will not have an incentive to abuse their market power anymore so that a price regulation becomes inappropriate as soon as non-aviation revenues increase above 50% of all airport revenues. --airport regulation,aviation and non-aviation revenues,complementarity of aviation and non-aviation,locational rents
Variations on the Author
No full text“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
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
