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
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

Risonanza Magnetica delle lesioni focali epatiche: valutazione contrastografica dinamica con gadolinio vs mezzo di contrasto epatospecifico reticolo-endoteliale.
No full textPURPOSE: To compare the potentials of AMI-25 (Endoren) to those of Gadolinium
with the dynamic contrast-enhanced technique in the differential diagnosis of
focal liver lesions.
MATERIAL AND METHODS: Forty patients with at least one focal liver lesion
diagnosed at US underwent MRI. We used a 1.5 T unit and employed single-shot
half-Fourier T2-weighted FSE and spoiled gradient-echo T1-weighted sequences
before and after Gadolinium injection. Multiple acquisitions were obtained during
the arterial, portal and delayed phases. Twenty-four to 48 hours later
T2*-weighted GRE and SPGR/90 degrees sequences were obtained after AMI-25
administration. In the characterization of solid lesions the gold standard was
biopsy performed with a shearing needle; for the diagnosis of angiomas and of 11
metastatic lesions we considered follow-up and clinical data as important
diagnostic elements.
RESULTS: We found 12 hepatocarcinomas, 14 metastases, 4 cases of focal nodular
hyperplasia (FNH), 4 adenomas and 6 angiomas. The diagnosis was correct and
confirmed by the conventional examination in all cases but 2 adenomatous lesions
and 2 angiomas. Precontrast studies showed slight hyperintensity in 2 of 4 cases
of FNH, while the other 2 lesions appeared isointense and were therefore detected
only on postcontrast images, where there was contrast agent uptake during the
arterial phase and rapid washout. We found only one central scar hyperintense on
T2- and hypointense on T1-weighted images. After AMI-25 administration all
lesions appeared isointense to surrounding parenchyma on T2* GRE sequences.
Adenomas were isointense in the precontrast phase and postcontrast 3 of them
showed strong Gadolinium uptake and rapid washout. After AMI-25 two of the 4
lesions were hyperintense while the other two were isointense to the parenchyma.
Four of 6 angiomas exhibited a typical pattern characterized by signal
hyperintensity on T2-weighted sequences and on AMI-25-enhanced T1- and
T2-weighted sequences. Two angiomas were supposed to be of malignant nature but
histology showed the presence of a strong fibrotic component. Hepatocarcinomas
could be detected on precontrast images. After Gadolinium administration 10
lesions appeared hyperintense in the arterial phase and 2 were hypointense. After
AMI-25 all lesions exhibited homogeneous signal hyperintensity and appeared
slightly bigger than on Gadolinium-enhanced images. The metastases were only
partly demonstrated by MRI. Postgadolinium studies showed 13 lesions with
hyperintense signal in the portal phase. AMI-25 administration detected 14
lesions that appeared slightly bigger than on Gadolinium-enhanced images.
CONCLUSIONS: AMI-25 can help also in characterizing primary lesions with an
atypical signal pattern after contrast agent administration thanks to its
intrinsic capability of accumulating in benign lesions. However it remains
difficult to characterize well differentiated hepatocarcinomas and adenomas.
Finally, AMI-25 improves MR capabilities in detecting secondary lesions and
possible satellite nodules
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

اسلم کولسری کی غزل:بیان و بدیع کے تناظر میں: ASLAM KOLSARY’S GHAZAL IN THE LIGHT OF BIAN-O-BADIE
No full textAslam kolsari is new significant and potentially well-known personality for contributing to modern Urdu ghazal. Being a mindful and multidimensional literary figure he has specific fame in poetry. A distinguish diction in poetry is individuality specifically connected with his name. His ghazal contains all attributes of Research and criticism. Communication of an ordinary concept in his poetry is reflection of Aslam kolasri. In this article the author has explored how poetic characteristics distinguished Aslam kolsari
Self-similar regimes in Unstably Stratified Homogeneous Turbulence
No full textUnstably stratified homogeneous turbulence develops at late time a self-similar dynamics characterized by an exponential growth of turbulent quantities. It is believed from recent theoretical studies that different growth rates are possible, depending on the initial distribution of energy at large scales. In order to confirm these predictions, we run both highly resolved direct numerical simulations and a spectral model based on an eddy-damped quasi-normal closure. In addition to confirming the influence of initial conditions, our study sheds light on the anisotropic structures of the self-similar regimes
