Subjects in Difference: Walter Benjamin, Frantz Fanon, and Postcolonial Theory
This essay aims to rethink historical difference in light of Walter Benjamin’s formulation of mimesis and Frantz Fanon’s phenomenology of difference. Divided into three parts, the essay engages Dipesh Chakrabarty’s account of historical difference, considers how an understanding of mimesis might safeguard against some of the philosophical pitfalls within Chakrabarty’s formulation, and revisits Fanon for an explication of a theory of mimesis and difference that may be the grounds for a renewed understanding of historical difference. The essay makes a case for the relevance of Frankfurt School dialectics for postcolonial problematics

Poverty, inflation and economic growth: empirical evidence from Pakistan
This study aims to investigate the role of economic growth and inflation in explaining the prevalence of poverty in Pakistan. ARDL bound testing approach to co-integration confirms the existence of long run relationship among the variables of poverty, economic growth, inflation, investment and trade openness over the period of 1972-2008. Empirical results show that economic growth and investment have negative and inflation has positive impact on poverty. The effect of trade openness on poverty is insignificant in this study. The short run analysis reveals that economic growth has negative and inflation has positive impact on poverty whereas the role of investment and trade openness in poverty reduction in short run is not significant.Poverty, Inflation, Economic Grovvth, Pakistan, Macroeconomic Policy, Welfare, Trade Openness
An analysis of different approaches to women empowerment: a case study of Pakistan
Women empowerment has attracted the attention of researchers as an active area of research since 1980s. It can be viewed as an ultimate end as well as a mean to achieve other development goals. The present study is an attempt to investigate how consciousness /sensitization of women about their rights, economic empowerment of women and women’s overall development can be helpful in achieving the goal of women’s empowerment. The study uses data for the period of 1996 to 2009 for Pakistan. Empirical results reveal that consciousness of women about their rights, economic empowerment of women and women’s overall development have positive and significant effect on women’s empowerment as measured by Gender Empowerment Measure (GEM) index. Granger Causality Test confirms the existence of bi-directional causality between women’s overall development and women’s empowerment. A unidirectional causality exists between sensitization of women and women’s empowerment
A new outranking method for multicriteria decision making with complex Pythagorean fuzzy information
[EN]This article contributes to the advancement and evolution of outranking decision-making methodologies, with a novel essay on the ELimination and Choice Translating REality (ELECTRE) family of methods. Its primary target is to unfold the constituents and expound the implementation of the ELECTRE II method for group decision making in complex Pythagorean fuzzy framework. This results in the complex Pythagorean fuzzy ELECTRE II method. By inception, it is intrinsically superior to models using one-dimensional data. It is designed to perform the pairwise comparisons of the alternatives using the core notions of concordance, discordance and indifferent sets, which is then followed by the construction of complex Pythagorean fuzzy concordance and discordance matrices. Further, the strong and weak outranking relations are developed by the comparison of concordance and discordance indices with the concordance and discordance levels. Later, the forward, reverse and average rankings of the alternatives are computed by the dint of strong and weak outranking graphs. This methodology is supported by a case study for the selection of wastewater treatment process, and by a numerical example for the selection of the best cloud solution for a big data project. Its consistency is confirmed by an effectiveness test and comparison analysis with the Pythagorean fuzzy ELECTRE II and complex Pythagorean fuzzy ELECTRE I methodsPublicaciĂłn en abierto financiada por el Consorcio de Bibliotecas Universitarias de Castilla y LeĂłn (BUCLE), con cargo al Programa Operativo 2014ES16RFOP009 FEDER 2014-2020 DE CASTILLA Y LEĂ“N, ActuaciĂłn:20007-CL - Apoyo Consorcio BUCL
Toward high-quality gradient estimation on regular lattices
Abstract—In this paper, we present two methods for accurate gradient estimation from scalar field data sampled on regular lattices. The first method is based on the multidimensional Taylor series expansion of the convolution sum and allows us to specify design criteria such as compactness and approximation power. The second method is based on a Hilbert space framework and provides a minimum error solution in the form of an orthogonal projection operating between two approximation spaces. Both methods lead to discrete filters, which can be combined with continuous reconstruction kernels to yield highly accurate estimators as compared to the current state of the art. We demonstrate the advantages of our methods in the context of volume rendering of data sampled on Cartesian and Body-Centered Cubic lattices. Our results show significant qualitative and quantitative improvements for both synthetic and real data, while incurring a moderate preprocessing and storage overhead. Index Terms—Approximation theory, Taylor series expansion, normal reconstruction, orthogonal projection, body-centered cubic lattice, box splines. Ç
Self-interaction errors in density functional calculations of electronic transport
All density functional calculations of single-molecule transport to date have
used continuous exchange-correlation approximations. The lack of derivative
discontinuity in such calculations leads to the erroneous prediction of
metallic transport for insulating molecules. A simple and computationally
undemanding atomic self-interaction correction greatly improves the agreement
with experiment for the prototype Au/dithiolated-benzene/Au junction.Comment: 4 pages. Also available at http://www.smeagol.tcd.i
Incoherent Transport through Molecules on Silicon in the vicinity of a Dangling Bond
We theoretically study the effect of a localized unpaired dangling bond (DB)
on occupied molecular orbital conduction through a styrene molecule bonded to a
n++ H:Si(001)-(2x1) surface. For molecules relatively far from the DB, we find
good agreement with the reported experiment using a model that accounts for the
electrostatic contribution of the DB, provided we include some dephasing due to
low lying phonon modes. However, for molecules within 10 angstrom to the DB, we
have to include electronic contribution as well along with higher dephasing to
explain the transport features.Comment: 9 pages, 5 figure
