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

Peridynamics for Failure Prediction in the Presence of Material Nonlinearity and Finite Deformation
No full textThis study examines the failure modeling of materials exhibiting nonlinear behavior and reduced dimension structures using peridynamic (PD) theory. Among the existing PD models, PD constitutive correspondence approach is adopted in the development. PD correspondence approach offers a way to use constitutive equations from classical continuum mechanics by defining a nonlocal deformation gradient tensor. However, using the original definition of deformation gradient leads to spurious oscillations in the solution. This work uses a bond-associated deformation gradient with the peridynamic differential operator to eliminate these oscillations. The numerical modeling assumes the quasi-static loading conditions, and the solution is obtained using the implicit technique with the Intel PARDISO solver using the exact tangent stiffness matrix. PD models are systematically developed for rubber-like materials, polymers exhibiting high stretch, and epoxy adhesives. The force density vectors for rubber materials are derived using the neo-Hookean constitutive equation. The weak form of PD equilibrium is used to impose the boundary conditions directly on the last layer of material points. Stretch-based criterion is used to eliminate interaction during failure simulations. The validity for predicting damage is demonstrated through simulations of experiments concerning progressive damage growth in pre-notched styrene-butadiene rubber sheets. The formulation is then extended for the polymer that can sustain high stretches. Anand’s model and Talamini-Mao-Anand’s model are used to derive force density vectors. The fidelity of this PD model for predicting large deformation, progressive damage, and rupture is established by comparison with experimental measurements of polymer sheets with defects under displacement-controlled tensile loading. To model epoxy adhesives, a viscoelastic material model in the presence of finite deformation is employed to derive the force density vectors. The relaxation modulus for the time-dependent behavior of the viscoelastic material is described in terms of the Prony series. The model performs well in predicting interface failure of lap joint configurations.
A new approach is presented to impose traction and displacement boundary conditions while solving for the strong form of PD equilibrium equations without a fictitious boundary layer. The domain is split into inner, outer, and boundary layer regions. In the “interior” region, the equilibrium equations are based on the nonordinary state-based (NOSB) peridynamics. In the “outer” region, the equilibrium equation is derived based on PD differential operator (PDDO). The PD form of traction components based on the PDDO enables the imposition of traction conditions in the actual “boundary layer” region. The displacement constraints are also enforced directly in the real boundary layer. The present approach is free of the unphysical displacement kinks near the boundaries. Also, the displacement predictions maintain the smoothness between the outer and inner regions. The displacement predictions agree well with FE results for all combinations of boundary conditions. The approach is adopted to model the creep behavior of stainless steel at high temperatures. Liu and Murakami's creep damage model is adopted to derive the force density vector. The approach is validated by considering the creep deformation of uniaxial and 2D plane stress stainless steel specimens subjected to a range of constant stress. The results compare well with the experimental measurements and analytical solutions.
A generalized PD beam model is formulated based on the Simo-Reissner beam theory. The governing equations are developed based on the form invariance of the first law of thermodynamics under rigid body motion. Nonlocal measures of strain and curvature are defined using the PD differential operator (PDDO). By employing a quadratic strain energy density function for the material response, the present approach is validated by considering numerical examples of beams undergoing large deformation
MEASURING SOCIO-ECONOMIC PROGRESS IN INDIA: ISSUES AND CHALLENGES
Full text linkOne of the challenges to the National Statistical Systems worldwide is to capturethe indicators of socio-economic progress from the current available framework. The limitsof traditional indicators provide little insights about the extent of well being realised in thesociety, since there is no automatic link between growth and development which aims atimproving human and social welfare. Therefore, different countries had tried variousapproaches to measure their progress of the society. India’s experience with measuringprogress in the society ranges from computation of composite index to adoption of adevelopment strategy that emphasises human welfare and well-being of the society ascentral to all development planning. In this connection, this paper limits its scope to some ofthe challenges and possibilities in the Indian system for developing the indicators of socialprogress
