Compact shorted 1350 Sectoral microstrip antenna derived from 2700 Sectoral microstrip antenna is proposed. On thicker air substrate (h > 0. 1?0) it yields bandwidth of more than 350 MHz (35%). To increase the bandwidth, its rectangular slot cut variation is proposed. The slot reduces the resonance frequency of higher order TM1/4,1 mode of the shorted patch and along with fundamental TM1/4,0 mo...

Drawing on a sample of participants in El Salvador’s El movimiento popular, the paper examines how structural location in the resistance movement’s multi-sectoral organizational infrastructure shapes the level of participation. Those motivated by state repression and mainta...

Does unbalanced sectoral productivity growth inevitably lead to continuous shift of resources to the less productive sectors and stagnation in aggregate productivity? This paper attempts to integrate the traditional stagnationist and the modern optimist arguments within a numerical simulation framework. The simulation framework consists of an applied general equilibrium multi-sectoral growth mo...

This paper quantifies the contributions of sectoral productivity growth and structural change to aggregate productivity convergence. Existing evidence is inconclusive because it focuses on convergence within sector and its methodology depends sensitively on the conversion factor used to compare sectoral productivity levels across countries. Thus, a methodology – β-decomposition – is proposed to...

The objective of this paper is to capture the extent of sectoral heterogeneity across Professional Service sectors. It is argued that ongoing scholarly disputes on their boundaries within the geography of industry have lost sight of the intrinsic diversity that characterizes these activities. The present study connects this cue to research on sectoral patterns and elaborates an empirical analys...

Abstract By reviewing economic performance, two main phenomena could be identified: The first phenomenon is prior to the third wave of the Industrial Revolution in which limited resources are the predominant input; in other words, physical and natural resources are much more credited than human resources. The second phenomenon resonates with the third wave of industrial revolution to the presen...
