Fiscal Policy and Current Account Dynamics in Case of Pakistan

The study empirically investigates the effects of fiscal policy or government budget deficit shocks on the current account and the other macroeconomic variable: real output, real interest rate and exchange rate for Pakistan over the period 1960-2009. The structural Vector Autoregressive model is employed; the exogenous fiscal policy shocks are identified after controlling the business cycle effects on fiscal balances. The results suggest that an expansionary fiscal policy shock improves the current account and depreciates the exchange rate. The rise in private saving and the fall in investment contribute to the current account improvement while the exchange rate depreciation. The twin divergence of fiscal deficit and current account deficit is also explained by the output shock which seems to drive the current account movements and its comovements with the fiscal balance.Restricted Vector Autoregressive model, current account, government budget deficit, fiscal policy, exchange rate

Germanium-on-silicon mid-infrared waveguides and Mach-Zehnder interferometers

In this paper we describe Ge-on-Si waveguides and Mach-Zehnder interferometers operating in the 5.2 - 5.4 mu m wavelength range. 3dB/cm waveguide losses and Mach-Zehnder interferometers with 20dB extinction ratio are presented

Low Complexity Blind Equalization for OFDM Systems with General Constellations

This paper proposes a low-complexity algorithm for blind equalization of data in OFDM-based wireless systems with general constellations. The proposed algorithm is able to recover data even when the channel changes on a symbol-by-symbol basis, making it suitable for fast fading channels. The proposed algorithm does not require any statistical information of the channel and thus does not suffer from latency normally associated with blind methods. We also demonstrate how to reduce the complexity of the algorithm, which becomes especially low at high SNR. Specifically, we show that in the high SNR regime, the number of operations is of the order O(LN), where L is the cyclic prefix length and N is the total number of subcarriers. Simulation results confirm the favorable performance of our algorithm

Pengaruh Pelatihan dan Motivasi Kerja terhadap Kinerja Karyawan PT. PLN (Persero) Cabang Pekanbaru

The purpose of this research to explain the effects of Training and Work Motivation simultaneously and partially on Employee Performance at The Branch of Pekanbaru This research used pimary data that obtained from interviews and the questionnaire to all employees at The Branch of Pekanbaru Secondary data relating to organizational structure. Population in this research were all employees that consist of 81 people. Methods of analysis used in this research is the method of multiple linear regression.The results of the testing that has been done, simultaneous regression test (uji-F) suggests that Training and Work Motivation variables simultaneously have significant effect on Employee Performance. On the partial test (uji-t) results indicate that the variables of Training and Work Motivation are partially significant efeect on Employee Performance. This writer concluded that the variable of Training and Work Motivation simultaneously and partially influenced positively and significantly toward Employee Performance PT. PLN (Persero) the Branch Of Pekanbaru.Keywords : Training, Work Motivation and Employee Performanc

Blood, Bone and Brain Nocardiosis Infection in an HIV-Infected Man

Disseminated nocardiosis is a rare and complicated opportunistic bacterial infection with propensity of delay in establishing the correct diagnosis and high frequency for misdiagnosis and due to the non-specific clinical presentation and the inherent difficulty in cultivating the organism. The infection is caused by gram-positive aerobic actinomycetes in the genus Nocardia. A definitive diagnosis requires the isolation and identification by Gram stain and modified acid-fast stain from a clinical specimen. Treatment heavily relies on species and susceptibility testing. There is a real paucity of prospective studies in nocardiosis infection, resulted in severely limited understanding of its diagnosis and treatment among the medical community. We report a clinical case of a 42-year old HIV-infected Burmese man with culture proven Nocardia infection
