La localizzazione della politica nei regimi ibridi dell’Asia meridionale. “Casta” e democrazia in Pakistan
No full textDespite their seemingly different political paths, India and Pakistan have both experienced a shift from the national to the local dimension of politics. The reasons behind this shift are assumed to be of a quite different nature. In the case of India, this evolution is widely connected to the crisis that has affected the Congress since the late 1980s, and, secondly, to the political strategy followed by Indira Gandhi in the 1970s and the early 1980s of disconnecting the traditional links of the party to the regional notables. Both elements contributed to make the Congress increasingly dependent on regional caste/kinship-based political organizations. The similar evolution observed in Pakistan has been explained, in part, with reference to the structural weakness of the mainstream political parties - in particular the Pakistan People Party and the Pakistan Muslim League – and their dependence on kinship and religious structures and hierarchies, and, in part, with the impact of military regimes. The latter would have constantly aimed to depoliticizing society by putting formal and informal obstacles to the activities of the political parties, and reinforced the biradari (extended family/caste) loyalties at the provincial and district level. There is however a relevant difference between the two cases, in so far the role played by castes in India has been since long identified as a factor that favors democratization. A recent analysis has even emphasized a “vernacularization” of democracy (Michelutti 2007). On the contrary, in the Pakistani case, “caste” groups have been identified as an obstacle towards the consolidation of democracy. While in both cases the evolution of the political system seems to emphasize the relevance of political culture for the process of democratization, the result seems to be radically different. The paper will aim to discuss this paradox, through an analysis of the role played by descent groups in the electoral process and the political bargaining in an area of South Western Punjab in Pakistan
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
Variations 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
Validation of an Electrochemical Detection–High-Performance Liquid Chromatography Method for Simultaneous Determination of Lignans in Flaxseed (Linum usitatissimum L.)
No full textFlaxseed is a major source of lignans, which are
important bioactive compounds. The aims of this work were
to validate a liquid chromatographic method for the rapid
and simultaneous determination of the main lignans in flaxseed
using high-performance liquid chromatography coupled
with electrochemical detection and to analyze the composition
of commercial samples of flaxseed. The performance
criteria of the proposed method demonstrate that the method
can be used for the analysis of secoisolariciresinol diglucoside
(SDG), secoisolariciresinol (SECO), matairesinol (MATA),
pinoresinol (PINO), lariciresinol (LARI), hydroxymatairesinol
(HYDROXY), and isolariciresinol (ISOLARI) in flaxseeds at
suitable levels. Calibration curves were determined for six
different concentrations of standard solutions injected in triplicate.
The sensitivity of the calibration curve was evaluated
considering the confidence intervals of the intercept and slope.
The limit of detection and limit of quantification were 7.4 and
10.9 μg/l, respectively, for LARI and 17.7 and 37.5 μg/l,
respectively, for MATA. The relative standard deviation of
repeatability values were lower than 2.59 %, which are acceptable
because the Horwitz ratio values were 0.1 for all of the
lignans. The recoveries of lignans were in the range of 74–
100 % of SECO, which are consistent with the literature. The
precision of the proposed method was determined by analyzing
four flaxseed samples of different years and varieties. SDG was
the main lignan present in all the samples, followed by
ISOLARI and HYDROXY
