Fiscal Deficits and Debt Dimensions of Pakistan

Pakistan continues to suffer from a syndrome of high fiscal deficits and severe incidence of debt. Its annual fiscal deficit has stayed constantly at over 6 percent of GDP especially since 1990 [Pakistan (1997-98)]. The prevalence of such a high fiscal deficit over the years in a row has propelled increased borrowing from both internal and external sources to cover the resource gap. With inadequate improvement in the repayment capacity of the country debt has continued to accumulate at a massive rate. Serving as the cause and effect of each other, the volumes of both the fiscal deficit and debt have soared continuously. The most devastating consequence of high fiscal deficit and soaring debt has been the continuous accrual of massive debt-servicing. In fact, both the debt and debt-servicing have reached unaffordable limits. How to alleviate this situation has become the foremost issue of the country. While complete elimination of all the debt and thereby debt-servicing may not be easy to accomplish in the short run, efforts are needed to systematically bring the fiscal deficit down to a minimum affordable limit. What may be the minimum financeable level of fiscal deficit and how it may be reduced to that level are the issues addressed in this paper.

February 2001 Crisis in Turkey: Causes and Consequences

Turkey has suffered from different economic crises since 1990. However, the February 2001 crisis has been unprecedented in intensity and repercussions. Although many factors, both internal and external, may have contributed to their occurrences, the former owing to their inducing corruption and waste in the economy, seem to have fomented them more than the latter. Although Turkey has been getting transformed into a market economy since 1980, government intervention is still pervasive in its economy. Government still controls Central Bank, owns commercial banks, and operates public enterprises. It has liberalised market, currency, foreign trade and foreign direct investment (FDI), but still operates sectors like energy, sugar and tobacco. Such a level of state intervention had adverse implications for corruption, waste, effective reforms, etc. in the country. Further, since the transformation of the economy could not be accompanied by concomitant structural, legal and institutional reforms in 1990s, resources have constantly been misused over the years. Further still, groups owning bank, media and holding companies jointly have notoriously precipitated domestic financial crisis by stashing away the home deposits in their offshore branches. Finally, supporting agriculture and industry with politically-motivated credit for voting purposes has constantly been aggravating the drain of resources and thereby financial crises of the country. This paper attempts a critical examination of how such factors may have contributed to the occurrence and accentuation of economic crises suffered by Turkey over the last decade.

Properties of the integrated spectrum of serendipitous 2XMM catalogue sources

Our analysis is aimed at characterizing the properties of the integrated spectrum of active galactic nuclei (AGNs) such as the ubiquity of the Fe K{\alpha} emission in AGNs and the dependence of the spectral parameters on the X-ray luminosity and redshift. We selected 2646 point sources from the 2XMM catalogue at high galactic latitude (|BII| > 25 degrees) and with the sum of EPIC-PN and EPIC-MOS 0.2-12 keV counts greater than 1000. Redshifts were obtained for 916 sources from the NED. The final sample consists of 507 AGN. Individual source spectra have been summed in the observed frame to compute the integrated spectra in different redshift and luminosity bins over the range 0<z<5. Detailed analysis of these spectra has been performed. We find that the narrow Fe K{\alpha} line at 6.4 keV is significantly detected up to z=1. The line equivalent width decreases with increasing X-ray luminosity in the 2-10 keV band (''IT effect''). The anti-correlation is characterized by the relation log(EWFe) = (1.66 +/- 0.09) + (-0.43 +/- 0.07) log(LX,44), where EWFe is the rest frame equivalent width of the neutral iron K{\alpha} line in eV and LX,44 is the 2-10 keV X-ray luminosity in units of 10^{44} erg s^{-1}. The equivalent width is nearly independent of redshift up to z ~ 0.8 with an average value of 101+/-40 (rms dispersion) eV in the luminosity range 43.5<= logLX <= 44.5. Our analysis also confirmed the hardening of the spectral indices at low luminosities implying a dependence of obscuration on luminosity. We confirm that the neutral narrow Fe K{\alpha} line is an almost ubiquitous feature of AGNs. We find compelling evidence for the ''IT effect'' over a redshift interval larger than probed in any previous study. We detect no evolution of the average rest frame equivalent width of the Fe K{\alpha} line with redshift.Comment: 10 pages, 7 figures, 2 Tables. A&A in pres

Controlling a remotely located Robot using Hand Gestures in real time: A DSP implementation

Telepresence is a necessity for present time as we can't reach everywhere and also it is useful in saving human life at dangerous places. A robot, which could be controlled from a distant location, can solve these problems. This could be via communication waves or networking methods. Also controlling should be in real time and smooth so that it can actuate on every minor signal in an effective way. This paper discusses a method to control a robot over the network from a distant location. The robot was controlled by hand gestures which were captured by the live camera. A DSP board TMS320DM642EVM was used to implement image pre-processing and fastening the whole system. PCA was used for gesture classification and robot actuation was done according to predefined procedures. Classification information was sent over the network in the experiment. This method is robust and could be used to control any kind of robot over distance

Buying Practices and Prevalence of Adulteration in Selected Food items in a Rural Area of Wardha District: A Cross - Sectional Study

Introduction: Food adulteration in India includes both willful adulteration and substandard food which do not confirm to prescribe food standard. There is striking paucity of reliable data with regard to extent of adulteration and documentation of food borne illnesses reflecting lack of attention and focus on this problem. Objectives: To find the prevalence of food adulteration, buying practices of selected food items and their awareness towards food adulteration act. Also assess relationship between per-capita incomes, education of respondents, and food borne illnesses with magnitude of adulteration in each house-hold. Methods: With the best estimate of 50%, sample size comes to 89. By stratifying the village according to social strata and randomly selecting the households with PPS. Questionnaire was administered to fulfill our objectives and food items were tested. Data analyzed by numeral with percentage, Pearson moment correlation, F test and chi square test. Results: In 68.5% Households, wife (home-maker) buys the grocery. Majority of them never read the food labels. All the selected food items were adulterated ranging from 76 % to 11%. Mean percentage of purity was highest in literates (47.5 ± 22.48) than illiterates and just literates. Food borne illness was prevalent in households with low purity of food. Association was found between per capita income and percentage of purity (0.765)

Rest-frame stacking of 2XMM catalog sources : Properties of the Fe Kalpha line

The aim of this work is to characterize the average Fe K emission properties of active galactic nuclei (AGNs) in the source rest-frame. We selected a sample of 248 AGNs from the 2XMM catalog, covering a wide redshift range 0 < z < 5 and with the EPIC-PN net 2-10 keV rest-frame counts >=200 and power law photon indices in the range 1.5-2.2. We employed two fully independent rest-frame stacking procedures to compute the mean Fe K profile. The counting statistics for the integrated spectrum is comparable to the one available for the best studied local Seyferts. To identify the artifacts possibly introduced by the stacking procedure, we have carried out simulations. We report that the average Fe K line profile in our sample is best represented by a combination of a narrow and a broad line. The equivalent widths of the narrow and broad (parametrized with a diskline) components are ~30 eV and ~100 eV, respectively. We also discuss the results of more complex fits and the implications of the adopted continuum modeling on the broad line parameters and its detection significance.Comment: 13 pages, 13 figures, Accepted for publication in A&
