A layperson’s guide to Federal Budget 2012-13

As Finance Minister Abdul Hafeez Sheikh presents the budget this Friday (06-03-2012), the last of the incumbent PPP-led government, it is high time to make an attempt at discovering what is hidden story behind the numbers. The idea is to enable the reader to: 1) understand the main issues involved in the budget; 2) comprehend the fierce competition between different sectors vying for the scarce resources; 3) read between the lines because the government mostly hides its inefficiency through jugglery of figures; 4) evaluate the government’s revenue and expenditure priorities over the past four years with a view to gauging which sectors have won and which ones have lost during this period; and 5) do a basic level analysis of the budget as the finance minister unveils the budget proposals. We have identified eight areas of the budget that need special attention and we request the finance minister to clearly spell out his government’s policy reagrding them. We also  request him to use a uniform measure for the comaprison of budgetary figures: either ‘estimates’ or ‘revised estimates’.

Resources mean how much money the government will gather in a year, and how it will gather it; while expenditure means how much money the government will spend in that same year, and on what.
In the outgoing budget, the total resources (internal and external) were estimated at Rs2,463 n; while the total expenditure (current and development) at Rs2,767 billion. The deficit is covered through bank borrowings.
Issue: Overestimation of resources and underestimation of expenditure.

Current or recurring expenditure includes government spending on salaries, rentals, operating expenses of public-sector industries and payment of interest on loans; while development expenditure includes government spending on new projects – schools, health units, roads, dams, etc. – that have a life of more than one year.
In the outgoing budget, current expenditure was estimated at Rs2,315 billion; while the PSDP at Rs730 billion.
Issue: Overestimation of the PSDP and underestimation of current expenditure.

Direct taxes are paid directly to the government and only the people above a certain level of income have to pay them; while indirect taxes (mainly sales tax, customs duties and federal excise) are levied on commodities and transactions, and are paid to a second party, which then passes them onto the government.
In the outgoing budget, direct taxes was estimated at Rs627 billion; while indirect taxes at Rs1,052 billion.
Issue: Overestimation of direct taxes and underestimation of indirect taxes that affect all citizens.

Domestic debt servicing implies the interest paid on the money borrowed by the government from its own people; while foreign debt servicing implies the the interest paid on the money borrowed from external sources.
In the outgoing budget, domestic debt servicing was estimated at Rs715 billion; while foreign debt servicing at Rs76 billion.
Issue: Pakistan’s major problem is domestic debt, not foreign debt, since the interest on the former is many times higher than on the latter.

Mega projects such as highways and large dams have been a favourite with successive Pakistani governments because of the hype they create; while micro projects such as small dams or rural roads have received little attention over the years.
Issue: The centralised structure of a mega project makes its public scrutiny difficult. Also, such projects are prone to corruption in the form of kickbacks during the award of contracts. In comparison, micro projects can be better managed with people’s involvement

Tertiary education refers to public sector universities and colleges; while primary education to public sector primary schools.
In the outgoing budget, development budget for tertiary education was estimated at Rs29.111 billion; while for primary education at Rs4.148 billion.
Issue: Because of the lack of absorption capacity at the primary level, successive governments have allocated more funds to tertiary education, though the country’s foremost need is universal primary education.

Budget-making is a process of opting for some of the available priorities out of many. Traditionally, the PPP favours the agriculture sector, while the PML-N and dictatorial regimes favour the industrial sector.
In the outgoing budget, subsidies were estimated at Rs166 billion but the government has exceeded this figure. In addition, many incentives were offered to farmers.
Issue: The current government’s bias against the industrial sector is obvious and today the PPP-led government has the last chance to woo back its urban voters.

Budget is supposedly a gender-neutral document because the government does not discriminate between men and women while allocating resources or generating revenue. However, considering that the women lag behind men in almost areas, there is a dire need to allocate special funds for them to bring them on a par with men.
Issue: More budget allocations aimed at bridging the gap between women and men are needed. G ender budgets, which some of the ministries are already trying to introduce, should be the name of the game in future.

The government is often taken to task for inefficient management of the economy, but the real point is missed somewhere. A budget is not a scripture that cannot be changed; governments all over the world revise budgetary estimates throughout the year to cater to unseen challenges. For example, the floods last year necessitated a genuine revision of budgetary figures in Pakistan. However, a government has no justification to share incorrect revised estimates at the time of presentation of the next financial year’s budget.
It is important to remember that in Pakistan the financial year starts on July 1 and ends on June 30. As the federal budget for the next financial year is usually announced in the first week of June, it is impossible for the government to predict the exact budgetary figures of the outgoing financial year, because the latter is still not over. However, the revised budgetary estimates shared just one month before the end of a financial year should ideally not miss the target by much, as has been the case in Pakistan for the last few years.
There has been an increasing trend to project the revised budgetary figures of the outgoing fiscal year, included in the next financial year’s budget document, in a manner that they hide the government‘s inefficiency, which becomes evident only after the actual budgetary figures are released by the Finance Division in end August. As the focus of attention has drifted from the budget by then, the government does not have to face criticism from opposition parties, civil society or the media.
Comparisons make up the most of budget documents, though they are used in Pakistan to highlight ‘achievements’ only. To make these comparisons look good, the government does not hesitate to hide the reality where it is possible. For example, it always underestimates the expenditure, especially current, and overestimates the revenue in the revised estimates. This helps the government to show that not only its projections for the next financial year are realistic, but also its performance in the outgoing year had not been that bad. These budget discrepancies (for want of a better term) have resulted in an ongoing process where the government is forced to resort to the same practice year after year, bridging its budget deficit through bank borrowings, resulting in an increased burden on the economy and the masses in the form of interest paid.
In the revised estimates of the federal budget 2010-11, current expenditure was estimated at Rs2,296 billion, while the original estimate was Rs1,998 billion. With ‘fiscal discipline’ in mind, current expenditure in the federal budget 2011-12 was projected at Rs2,315 billion. This was being either overambitious or too simplistic because of the increasing inflation. However, the best is yet to come: according to the actual figures of the federal budget 2010-11, current expenditure reached an astounding Rs2,901 billion. Now, Rs605 billion is no mean sum, especially if we consider the fact that the revised estimates are prepared just one month before the end of a financial year.
The variation with the original estimates comes to an even more astounding Rs903 billion. Seen in this light, the estimate of Rs2,315 billion for the outgoing budget was all the more laughable. How could we be able to spend Rs586 billion less than we did last year? It is important to remember here that while the development expenditure can be reduced, by not initiating new schemes or stopping work on the ongoing ones, as we are currently experiencing, it is almost impossible to reduce current expenditure substantially, unless we agree to close down schools or hospitals, or lay off people working in the public sector.

Oropharyngeal Cancer


Intro

Oropharyngeal cancer is a disease which malignant cells form in the tissue of Oropharynx. Oropharynx is a middle part of the throat which includes the base of the Tongue, Tonsils, Palates (Soft and Hard) and walls of Pharynx. Oropharyngeal cancers can be divided into two types, HPV-positive, which are related to human papillomavirus infection, and HPV-negative cancers, which are usually linked to alcohol or tobacco use.

 Symptoms

Following are the possible signs of oropharyngeal cancer
  • A sore throat that persists
  • Pain or difficulty with swallowing
  • Unexplained weight loss
  • Voice changes
  • Ear pain
  • A lump in the back of the throat or mouth
  • A lump in the neck
  • A dull pain behind the sternum
  • Cough

Risk factors

Following are the risk factors that can increase the risk of developing oropharyngeal cancer.
Add caption
  • Smoking and chewing tobacco.
  • Heavy alcohol use.
  • A diet low in fruits and vegetables.
  • Chewing betel quid, a stimulant commonly used in parts of Asia.
  • Being infected with human papilloma virus (HPV).
  • EBV infection.
  • Plummer-Vinson syndrome.
  • Poor nutrition.
  • P53 mutation
CONDITIONS ASSOCIATED WITH MALIGNANT TRANSFORMATION
High-risk lesions
  • Erythroplakia
  • speckled Erythroplakia
  • Chronic hyperplastic candidiasis
Medium- risk lesions.
  • oral submucosal fibrosis
  • syphilitic glossitis
  • sideropenic dysphagia (or paterson-kelly-brown syndrome)
low-risk lesions.
  • oral lichen planus
  • discoid lupus erythematosus
  • discoid keratosis congenita.

Prognosis

Those with HPV-positive cancers tend to have higher survival rates. The prognosis for people with oropharyngeal cancer depends on the age and health of the person and the stage of the disease. It is important for people with oropharyngeal cancer to have follow-up exams for the rest of their lives as cancer can occur in nearby areas. In addition, it is important to eliminate risk factors such as smoking and drinking alcohol, which increase the risk for second cancers.

Spread

There are three ways of cancer spreading in the body.
  • Cancer invades the surrounding normal tissues.
  • Cancer invades the lymph system and travels through the lymph vessels to other places in the body.
  • Cancer invades the veins and capillaries and travels through the blood to other places in the body.

LEGO Robots Used to Generate Synthetic Bones


Scientists from the University of Cambridge are using robotics from the LEGO Mindstorms robot set to help produce samples of synthetic bone tissue. The team uses hydroxyapatite-gelatin composites to create the synthetic bone, which has low energy costs and improved similarity to the tissues they are intended to replace. Synthetic bone can provide a vast array of innovative applications; from medical implants to building construction, but producing samples of bone can be an intensive and — repetitive — process.

Daniel Strange, one of the PhD students working on the research, commented: “The great thing about the robots is once you tell them what to do they can do it very precisely over and over again — so a day later I can come back and see a fully made sample.”

The LEGO Mindstorms robotic kit includes motors, sensors and microprocessors that can be programmed to perform basic tasks on repeat. The team used the kit to build cranes to dip the sample into one beaker of calcium and protein, rinse it in some water and dip it into another beaker of phosphate and protein — this has to be done repeatedly to build up the compound.

Black Hole


1)       WHAT IS A BLACK HOLE:-
A black hole is a region of space-time from which nothing, not even light, can escape. The theory of general relativity predicts that a sufficiently compact mass will deform space-time to form a black hole. Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return. It is called "black" because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics. Quantum mechanics predicts that black holes emit radiation like a black body with a finite temperature. This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater.
Objects whose gravity field is too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace. The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was not fully appreciated for another four decades. Long considered a mathematical curiosity, it was during the 1960s that theoretical work showed black holes were a generic prediction of general relativity. The discovery of neutron stars sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality.

       
           HOW ARE THEY FORMED:-
Black holes of stellar mass are expected to form when very massive stars collapse at the end of their life cycle. After a black hole has formed it can continue to grow by absorbing mass from its surroundings. By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses may form. There is general consensus that supermassive black holes exist in the centers of most galaxies. In particular, there is strong evidence of a black hole of more than 4 million solar masses at the center of our galaxy, the Milky Way.



            EVENT HORIZON:-
The defining feature of a black hole is the appearance of an event horizon—a boundary in space-time through which matter and light can only pass inward towards the mass of the black hole. Nothing, not even light, can escape from inside the event horizon. The event horizon is referred to as such because if an event occurs within the boundary, information from that event cannot reach an outside observer, making it impossible to determine if such an event occurred.
As predicted by general relativity, the presence of a mass deforms space-time in such a way that the paths taken by particles bend towards the mass. At the event horizon of a black hole, this deformation becomes so strong that there are no paths that lead away from the black hole.
To a distant observer, clocks near a black hole appear to tick more slowly than those further away from the black hole. Due to this effect, known as gravitational time dilation, an object falling into a black hole appears to slow down as it approaches the event horizon, taking an infinite time to reach it. At the same time, all processes on this object slow down causing emitted light to appear redder and dimmer, an effect known as gravitational redshift. Eventually, at a point just before it reaches the event horizon, the falling object becomes so dim that it can no longer be seen.
On the other hand, an observer falling into a black hole does not notice any of these effects as he crosses the event horizon. According to his own clock, he crosses the event horizon after a finite time, although he is unable to determine exactly when he crosses it, as it is impossible to determine the location of the event horizon from local observations.

Pakistan Renewable Energy

Iran begins 70mw power supply:




After enhancing the capacity of the existing transmission line, Iran has increased power supply up to 70 MW to Pakistan from February 26, which is being supplied to the Makran Division in Balochistan. A spokesman for the Ministry of Water and Power said that the enhancement in power supply from Iran has made the coastal division of the Balochistan totally load shedding free areas. The import of 70 MW will help meet requirements for the next five years electricity demand of the division. Earlier, Pakistan was getting only 35 MW from Iran. All the power, coming from Iran is being supplied to the Makran division include Gwadar port, Gwadar district, Turbat, Panjgur, Mand and other areas of the division. The overall demand of the Makran division is 55 MW in summer and 40 MW in winter season.
Previously there was load shedding of 10 to 12 hours in all the areas of the division to keep intact the system. All the areas now are load shedding free in the Division. He said that two separate projects of importing 1000 MW and 100 MW from Iran were at the final stage of negotiations and construction of transmission lines would be started immediately after the finalisation of tariff. Meanwhile in a statement Minister for Water and Power Syed Naveed Qamar has said that the government was taking all steps to facilitate the people of Balochistan and special efforts were made to upgrade the transmission network within shortest possible time. He said that industrial, commercial and domestic consumers of the area will get benefit from this power and there will be also economic development there.

Fuel Consuption (Saving The Fuel)

In Pakistan vehicles have been used for transportation purpose since a long time and thus too much of fuel have been consumed which has caused the ratio of purchase and sell of fuel (patrol and gas) to a extreme level. The cost of fuel has also increased due to rise of fuel consumption ratio.
The Road sector energy consumption (% of total energy consumption) in Pakistan was reported at 12.73 in 2008, according to the World Bank. Road sector energy consumption is the total energy used in the road sector including petroleum products, natural gas, electricity, and combustible renewable and waste. Total energy consumption is the total country energy consumption. Pakistan's economy has suffered in the past from decades of internal political disputes, a fast growing population, mixed levels of foreign investment, and a costly, ongoing confrontation with neighboring India. However, IMF-approved government policies, bolstered by foreign investment and renewed access to global markets, have generated solid macroeconomic recovery during the last decade.
Motor vehicles include cars, buses, and freight vehicles but do not include two-wheelers. Population refers to midyear population in the year for which data are available.

So lets save fuel by starting to use our vehicles and other mechanical stuff the least and save the economy and environment of our country for us and our fellow brother countrymen.
