The purpose of this paper is to perform an analytical approximation for the flow of magnetohydrodynamic Carreau fluid with the association of nanoparticles over a rotating disk. The disk is moving with a constant uniform speed. Governing equations are obtained by using these assumptions in the form of partial differential equations with boundary conditions. These coupled, highly nonlinear equations are transformed into a coupled system of ordinary differential equations by engaging similarity transformation in the rotating frame of reference.

An efficient and reliable scheme, namely optimal homotopy asymptotic method, is used to obtain the solutions of the arising physical problem, which is further analyzed graphically. After computing the solutions of the arising problem, plots of velocities, temperature and concentration are discussed briefly.

It has been observed that dimensionless velocity reduced due to magnetic effect between the boundary layer and escalating values of the magnetic parameter upsurges the temperature and concentration profiles. Contour plots and numerical results are given for local numbers like skin friction coefficient, Nusselt number and Sherwood number.

The work presented in this manuscript is neither published nor submitted anywhere for the consideration/publications. It is a novel work.

The purpose of this paper is to study the heat and mass transfer with Soret-Dufour effects for the magnetohydrodynamic three-dimensional flow of second grade fluid in the rotating frame of reference.

Series solution is obtained by homotopy analysis method.

Increase in Soret number, Schmidt number and Dufour number, the heat transfer increases and mass transfer decreases. Effects of Prandtl and Eckert numbers are qualitatively similar as they assist the temperature profile and reduce the concentration of species. Increase in the length of the channel versus height increases the temperature profile but decreases the concentration field. Increase in the second grade fluid parameter causes reduction in both the temperature and concentration fields. The heat flux values at the lower plate are smaller than the values at the upper plate, whereas the situation is opposite in the case of mass transfer.

These findings will be useful for the fluid flow in porous channel.

The purpose of this paper is to explore the extent of corruption in India, Fiji and Ethiopia and survey citizen perception of how e‐governance could fight corruption. The main objective is to investigate and explore the potential of e‐governance applications in three countries representing three different regions of Asia, Africa, and Oceania.

A survey was conducted over 918 citizens in India, Ethiopia and Fiji using convenience random sampling. A structured questionnaire was used. The main emphasis of the survey was on citizen perception about corruption and poor service. It further asked respondents on how e‐governance can cut corruption.

Benefits of e‐governance in developing countries are the same as those in developed countries but there are many potential benefits that remain unreaped by developing countries as a consequence of their unlimited use of e‐governance. Based on these assertions, the researchers tried to evaluate and assess the potential of e‐governance initiatives in India, Ethiopia and Fiji. By exploring the role of e‐governance for reducing corruption that has afflicted the entire public sector in these countries, the main finding is that e‐governance is positively related to government, “citizen relationship and corruption reduction”.

This study is highly empirical and does not provide case studies to further extend on the findings.

The implications of the research are that information communication technology (ICT) needs to be effectively integrated in the development agenda of government plans in Ethiopia and Fiji. Government agencies in Ethiopia and Fiji do not seem to be much motivated to build sound government‐citizen partnerships. Citizens can see little of the internal workings of government. However, for India, where there are many e‐governance projects underway, and which is normally considered to be awakening to the challenges of e‐governance and which has to date many success stories relating to e‐governance, it is surprising to see that citizens find various existent formats of corruption and non‐transparent service delivery activities. It is quite evident that bureaucracy is more or less opaque and very little attention has been paid to improving transparency, including through the use of e‐governance processes. Time, cost and red‐tape procedures are major constraints in public service delivery.

The paper explores a problem that is of practical importance using principal‐agent theory, which is very applicable to the public sector context.

With an increasing thrust upon transparency and accountability in government, e-government platforms are being scaled in many countries to bolster trust of the citizens and to bring about efficiency in public service delivery. Recently, India launched its “Digital India” initiative as an e-government measure. This study aims to gauge respondents’ perceptions regarding corruption in public services post-launch of the “Digital India” initiative.

A survey was conducted via email, soliciting inputs from 217 respondents following a convenience sampling technique in selected districts of India. Using an institutional theory lens, this study uses a quantitative approach where correlations and hierarchical regression analysis inform the overall analysis.

The results showed that low transparency, high cost incurred in availing public services, inefficiency in government and favoritism in government are the key determinants that influenced the perception of users about corruption in e-government services. Also, one demographic variable, namely, gender, showed a statistically significant relationship with the perception of corruption in e-government services.

Hitherto, extant literature is replete with conceptual and theoretical studies on the impact of e-government initiatives on curbing corruption, and there is negligible empirical research in developing countries vis-à-vis this dimension – the present study seeks to fill this gap. Second, previous research has not used the institutional theory to investigate the efficacy of e-government initiatives; this study uses the framework of the institutional theory framework to substantiate the arguments.

The purpose of this paper is to underline the role of demographic variables as far as the perception of corruption among the Indian respondents is concerned.

Hierarchical regression analysis is conducted to ascertain the role of demographic variables in line with the study’s objectives.

Gender is a demographic factor that influences the perception of corruption by the respondents. Other demographic factors including education, marital status, professional status and age do not have any influence on the user perception of corruption in e-government services. Implicitly, there are differences in the manner in which men and women perceive the prevalence of corruption in India. Therefore, males perceive that corruption has decreased in e-government services post-launch of “Digital India” initiative and women perceive the opposite.

On the one hand, the study holds significance, in that no empirical investigation has been conducted which seeks to underline the impact of the “Digital India” initiatives on the citizen’s perception of corruption in public services. On the other hand, the present research is limited in the sense that only demographic variables are being probed in the present study with a small sample.

Studies in developing countries have remained few and far between despite the growing concern for existence of corruption in government services. The present study seeks to fill the gap by underlining the role of demographic variables as far as the perception of corruption in public services is concerned in the Indian context.

The purpose of this paper is to explore the link between corruption and government debt through a regime-based approach.

The empirical analysis makes use of a panel of 120 countries, spanning the period 1999–2015. The study makes use of the Panel Smooth Transition Regression (PSTR) methodological approach, as well as two alternative measures of corruption.

The empirical results document that the relationship between corruption and debt is non-linear, while a strong threshold effect was present as well. Public debt appears to respond faster to a high corruption regime compared to a low corruption regime, while an increase in the size of the shadow economy, government expenses, the inflation rate, interest payments on debt and military expenditure all increased the debt to GDP ratio. By contrast, an increase in GDP per capita, the secondary school enrollment ratio and the ratio of tax revenues to GDP led to a fall in the debt to GDP ratio. The findings survive certain robust checks when the role of the 2008 financial crisis is explicitly considered, as well as when two separate country samples were considered, i.e. developed vs developing countries.

Governments should aim to control both corruption and the size of the shadow economy if they really wish to reduce any high levels of their public debt. As debt levels respond faster to high corruption regimes, it is necessary that measures to reduce corruption are complemented by higher GDP per capita growth rates, enrolment rates and higher tax revenues.

The novelty of the paper is that it investigates for the first time, to the best of the authors’ knowledge, the presence of non-linearity between corruption and government debt. It proposes non-linear panel cointegration and causality tests, as well as a non-linear panel error correction model that allows for smooth changes between regimes, hence, examining causal relationships in each regime separately.

This paper addresses the three-dimensional flow of viscous nanofluid bounded by two plates. The lower plate stretches while the upper plate remains stationary. The fluid is electrically conducting in the presence of an applied magnetic field. In addition, the Hall, ion slip and Joule heating effects are retained. Governing equations for the considered physical happening are modeled under the phenomenon of boundary layer analysis.

Both analytical and numerical solutions for the resulting nonlinear system are derived. Numerical solutions have been presented by using bvp4c and NDSolve techniques. The homotopy analysis method is utilized for the development of convergent analytical solutions. A comparative study for the presented solutions is made. An excellent agreement between analytical and numerical solutions is noticed.

The dimensionless velocities, temperature and concentration are examined physically by two-dimensional plots, stream plot and tabular values. It is observed that Hall and ion slip parameters reduce the velocity field and temperature profile increases for the mounting values of the Eckert number.

This manuscript contains the novel contents which comprise the Hall and ion slip effects for the transportation of heat and mass for the flow of viscous nanofluid.

This study aims to analyze the effects of e-government on corruption prevalence by using a sample of 29 European countries over the period 2012–2019.

This paper uses the panel corrected standard errors (PCSE) model to mitigate the problems of cross-sectional dependence. The PCSE model is also considered to reexamine the findings when the presence of heteroscedasticity, fixed effects and endogeneity issues are taken into account. The theoretical model incorporates one-year-lagged explanatory variables to deal with endogeneity. The autoregressive distributed lag method using the dynamic fixed effects estimator is chosen to deal with the time and country-fixed effects in the effort to measure the short- and long-run effects of e-government more precisely.

The results indicate that e-government plays a critical role in improving the population’s perception of corruption. Furthermore, e-government appears to have an effect in the short run. Notably, the estimation results show that there is a nonlinear relationship between e-government, especially user centricity and key enablers and the corruption perception index in the U-shaped curve.

The short-run and nonlinear effects of e-government on corruption prevalence suggest that the fight against corruption requires countries to pursue a consistent and continuous improvement and development of the e-government system.

The authors contribute to the literature by providing a consistent and precise answer to this relationship in the case of European countries. Another contribution of the work is to use diverse indicators to reflect e-government in a typical country, which helps us confirm the reliability and robustness of the findings.

The purpose of this paper is to report on research that evaluates the perceived willingness of potential bidders to adopt public e-procurement for the supply of goods and services to the government of Nepal. The authors have identified anti-corruption attributes through an extensive literature review and developed a theoretical model representing the impact of four latent variables, monopoly of power, information asymmetry, trust and transparency and accountability on the dependent variable, the intent-to-adopt e-procurement (ITA).

Data for this research were obtained by the use of a questionnaire survey of bidders who were officially registered with the Government of Nepal. As part of the fieldwork for this research, the first author collected the perceptions of 220 bidders regarding the potential of public e-procurement to reduce corruption in public procurement processes.

The findings suggest that a high level of the ITA has a positive and significant relationship with the independent variables that might inform the developed and emerging countries to make a decision to adoption of e-procurement to combat corruption in public procurement.

This study has some limitations that should be taken into consideration. The evaluation of anti-corruption factors, as they affect the willingness of users to adopt e-procurement on the bidder’s perception research model is relatively new to e-procurement research. A limitation of the research was that it gathered and analyzed data from a single country with a limited number of respondents. More research is needed to identify the anti-corruption factors of e-procurement in reducing corruption, and also need strong empirical test to valid the factors that influence the adoption of e-procurement.

This study aimed to contribute to the academic scholar, government agencies and public procurement practitioner in enhancing their understanding of the perceived anti-corruption factors of public e-procurement to reduce corruption.
