Mimicry in Achebe’s Arrow of God

The paper is an attempt to study Chinua Achebe\u27s Arrow of God through the lens ofHomi K. Bhabha\u27s concept of ‘mimicry.\u27African Trilogy is a significant picture of African people and the history of how they are lured into a new culture. We see in the trilogy an evolution of mimic men ¬– how the native man evolves into an imitator. There are a lot of representations of mimic men available in the trilogy and they can be categorized into various phases of evolution of “mimic man” according to their ambivalence and hybridity level of their contemporary culture and society. The paper concentrates mainly on the characters of Arrow of God like Oduche and Unachukwu as they represent the universal condition and behaviour of mimic men

Rotational properties of two-component Bose gases in the lowest Landau level

We study the rotational (yrast) spectra of dilute two-component atomic Bose gases in the low angular momentum regime, assuming equal interspecies and intraspecies interaction. Our analysis employs the composite fermion (CF) approach including a pseudospin degree of freedom. While the CF approach is not {\it a priori} expected to work well in this angular momentum regime, we show that composite fermion diagonalization gives remarkably accurate approximations to low energy states in the spectra. For angular momenta $0 < L < M$ (where $N$ and $M$ denote the numbers of particles of the two species, and $M \geq N$), we find that the CF states span the full Hilbert space and provide a convenient set of basis states which, by construction, are eigenstates of the symmetries of the Hamiltonian. Within this CF basis, we identify a subset of the basis states with the lowest $\Lambda$-level kinetic energy. Diagonalization within this significally smaller subspace constitutes a major computational simplification and provides very close approximations to ground states and a number of low-lying states within each pseudospin and angular momentum channel

Public International Law and the WTO: A Reckoning of Legal Positivism and Neoliberalism

This Article proceeds in five parts. In part one, I review the scholarly skepticism as to how far international law is law in the hard sense and show that this skepticism has always permeated the discipline. In part two, I go on to examine what has prompted contemporary scholarship to credit the WTO with helping international law grow out of the thin normativity often attributed to it. The analysis suggests that certain features of legal positivism customarily associated with law in its strict sense, which were alleged to be lacking in international law, are found in the institutional apparatus of the WTO. To test this hypothesis, in part three, I examine that apparatus in light of the tenets of three prominent positivists-Bentham, Austin, and Hart-and enquire whether they would have sanctioned international law had the WTO existed in their day. The conclusion drawn is that, even with the WTO, their views on international law would not have been different than what they were. This finding rectifies the myths that regard the WTO as a positivist enterprise. Part four of the article undertakes to demonstrate that neoliberalism is the driving force of not only the WTO but also the normative and structural global changes all around. To this end, the analysis conceptualizes neoliberalism and then demonstrates how the WTO serves the implementation of the neoliberal agenda. As a corollary, in part five, positivism and neoliberalism are critically juxtaposed and shown to stand in harmony with one another. The conclusion highlights the extent to which the findings can restructure the outlook of international lawyers towards the WTO

Performance Comparison of Multi Input Capacitor Converter Circuits

This paper analyze the operation of a multi input switched capacitor (MIC) converters using a couple of switches, diodes and capacitors for several levels. With two input sources it is possible to obtain 8 output voltage levels. Here, 5 topologies of switched capacitor circuits namely summation, subtraction, inverting, double and half circuits are simulated and their performances are analyzed. Multi Input Converters have a high regard for multiple renewable energy sources used in smart grid systems, especially for distributed generators. The effects on output voltage with variation in load for different frequencies are also analyzed. Hardware implementation of summation and subtraction circuit is carried out and the results are compared with the simulated result

A Comparative Analysis on the Role and Market Linkages of Gold Backed Assets During COVID-19 Pandemic

Gold is a traditional favorite investment avenue for investors all over the globe, particularly during the crisis period. Irrespective of the nature of the crisis, investors are allocating their funds to different gold-backed assets. This paper uses various globally traded gold-backed assets to identify its role and market linkages during the Covid 19 pandemic. Daily prices of assets from March 2020 to January 2022 were employed. DCC GARCH model is used to ascertain time-varying correlations and quantile regression was employed to examine the relationship between assets in different quantiles. Based on the analysis, safe haven property of all the assets is revealed and it is associated with the severity of the stock market crash as specified by the quantiles. Moreover, double exposure of gold mining stock results in different flights to quality. Co-movement of gold bullion, gold futures, and gold volatility index is visible during this crisis. Gold Exchange Traded Funds and gold-backed cryptocurrency offer diversification by decoupling with gold bullion in the portfolio. The paper highlights the importance of the choice of gold-backed assets along with gold bullion in the investment portfolio based on its role and market linkages

Examining post COVID-19 tourist concerns using sentiment analysis and topic modeling

The COVID-19 pandemic has had a destructive effect on the tourism sector, especially on tourists’ fears and risk perceptions, and is likely to have a lasting impact on their intention to travel. Governments and businesses worldwide looking to revive and revamp their tourism sector, therefore, must first develop a critical understanding of tourist concerns starting from the dreaming/planning phase to booking, travel, stay, and experiencing. This formed the motivation of this study, which empirically examines the tourist sentiments and concerns across the tourism supply chain. Natural Language Processing (NLP) using sentiment analysis and Latent Dirichlet Allocation (LDA) approach was applied to analyze the semi-structured survey data collected from 72 respondents. Practitioners and policymakers could use the study findings to enable various support mechanisms for restoring tourist confidence and help them adjust to the ’new normal.
