Authentic leaders tend to be effective as managers

Leadership is the process of influencing a group of individuals to achieve shared objectives. The primary function of leadership is to produce change and movement, while the primary function of management is to provide order and consistency to organisations. As both leadership and management are processes, anybody can execute leadership or managerial functions at different times. Leaders cannot be called leaders simply by virtue of the position they hold in organisations. The execution of management and leadership functions by leaders situated in organisations is examined in this blog post

Essays on Public Spending in Education, Social Protection, and Infrastructure

In this dissertation, I visit areas of government spending that are core to human development and economic growth, and have equity and efficiency considerations. In the first essay, I examine the relationship between education and air pollution. How pollution affects education is typically studied through the health aspects of pollution exposure, and its subsequent effects on academic performance. This essay proposes a financing channel of pollution’s impact on education outcome. School districts with better air quality are endowed with higher tax base, and can generate more resources. Panel fixed effect analysis for a group of metropolitan school districts in the USA suggests that decrease in air pollution increases property tax revenue per pupil in the district. The second essay investigates the incidence of broad-based energy subsidies, and whether poor households could gain from targeted transfer programs financed by savings from reform. I analyze the tariff differential subsidy program in Pakistan, and find that the subsidy is regressive. I conduct a CGE exercise and find that reducing energy subsidy and redistributing savings to poor households, would improve poor household’s welfare. The third essay studies how public infrastructure capital affects growth in developing countries. The relationship between infrastructure and economic growth is widely studied in developed country context. This study contributes to literature by estimating output elasticities with respect to public infrastructure capital stock for two developing countries – Mauritius and Bangladesh. Estimated output elasticities are mostly positive for both countries, which suggests that public infrastructure stimulates economic growth in developing countries

Phase Transitions In An Implicit Solvent Minimal Model Of Lipids: Role Of Head-Tail Size Ratio

We present Monte Carlo simulations under constant NVT conditions on a minimal three beads coarse grained implicit solvent model of lipid molecules, with the hydrophilic head represented by one bead and the hydrophobic tail represented by two beads. We consider two lipids, one with the head and tail bead sizes equal and the other with the tail beads smaller than the head. When cooled to the ambient temperature from an initial isotropic phase at high temperature, the first lipid transforms spontaneously to a lamellar phase while the second lipid transforms to a micellar phase, showing the crucial role of the head and tail size ratio on lipid phases.Comment: conference pape

A new distributional record of Ficus altissima Blume (Moraceae) in Tripura: an occasionally confused fig species with Ficus benghalensis L.

The present communication is the first report of new distributional record of Ficus altissima Blume (Moraceae) in Tripura. F. altissima was found to be an important feeding and nesting habitat for forest frugivores, since the genus is very rich in diversity and is considered as a keystone species. This also possesses huge scope to understand the mechanism of interactions especially for conservation of rich avifaunal diversity. Brief description and field photographs are presented for facilitating easy identification of the species

A General Equilibrium Model of Value Added Tax Evasion: An Application to Pakistan

Value added taxes (VAT) constitute a major share of tax revenues in developing countries in which tax evasion is widespread. The literature on VAT evasion, however, is limited. This paper develops a computable general equilibrium framework for analyzing endogenous VAT tax evasion. The analytical framework entails increasing enforcement through greater spending on the enforcement of tax revenue collection. We assume that there is an elasticity that connects the changes in enforcement to actual increases in VAT collection. We apply the model to Pakistan data and show the level of enforcement spending required to achieve certain VAT collection targets. We also examine the short-, medium-, and long-term macroeconomic outlooks, and real consumption distribution across household economic groups associated with higher enforcement spending. We calibrate the model using 2016 as the base year and then run the dynamic model forward for 20 years. We define the implicit VAT rate as that hypothetical statutory rate that, in the absence of evasion, would approximately generate the observed VAT collection. We assume zero additional spending on enforcement in the baseline and estimate two alternative scenarios of VAT revenue target of 8% and 15% of the GDP. The alternative scenarios require increase in enforcement spending by a compounded 46.4% and 322.4%, respectively. We find that the increased enforcement spending enhances the sustainability of the government’s budget deficit without causing a decline in real GDP over the long-term. The interest and inflation rates are also lowered. However, there is a small regressive impact on households’ real consumption

Information transfer through a one-atom micromaser

We consider a realistic model for the one-atom micromaser consisting of a cavity maintained in a steady state by the streaming of two-level Rydberg atoms passing one at a time through it. We show that it is possible to monitor the robust entanglement generated between two successive experimental atoms passing through the cavity by the control decoherence parameters. We calculate the entanglement of formation of the joint two-atom state as a function of the micromaser pump parameter. We find that this is in direct correspondence with the difference of the Shannon entropy of the cavity photons before and after the passage of the atoms for a reasonable range of dissipation parameters. It is thus possible to demonstrate information transfer between the cavity and the atoms through this set-up.Comment: Revtex, 5 pages, 2 encapsulated ps figures; added discussion on information transfer in relation with cavity photon statistics; typos corrected; Accepted for Publicaiton in Europhysics Letter

Magnetism in small bimetallic Mn-Co clusters

Effects of alloying on the electronic and magnetic properties of Mn$_{x}$Co$_{y}$ ($x+y$=$n$=2-5; $x$=0-$n$) and Mn$_2$Co$_{11}$ nanoalloy clusters are investigated using the density functional theory (DFT). Unlike the bulk alloy, the Co-rich clusters are found to be ferromagnetic and the magnetic moment increases with Mn-concentration, and is larger than the moment of pure Co$_n$ clusters of same size. For a particular sized cluster the magnetic moment increases by 2 $\mu_B$/Mn-substitution, which is found to be independent of the size and composition. All these results are in good agreement with recent Stern-Gerlach (SG) experiments [Phys. Rev. B {\bf 75}, 014401 (2007) and Phys. Rev. Lett. {\bf 98}, 113401 (2007)]. Likewise in bulk Mn$_x$Co$_{1-x}$ alloy, the local Co-moment decreases with increasing Mn-concentration.Comment: 11 pages, 15 figures. To appear in Physical Review
