Embracing the truth of Dhamma to rise above the COVID catastrophe



by Randima Attygalle

As the entire world is clouded by the COVID-19 fright, Vesak full moon poya falling on May 7 brings a beacon of hope to Buddhists all over the world beckoning them all to revisit the timeless truth of Lord Buddha's words transcending ethnic and religious differences, that 'every human being is the author of his own health or disease' and 'health is the greatest gain.'

As a nation with a heritage nourished by the Buddhist philosophy for thousands of years, braving similar epidemics and pandemics in the history, we Sri Lankans are blessed with the gift of Dhamma to sustain us holistically through these testing times-physically, mentally and economically.

As custodians of a value system crowned with 'ayubowan' (may you live long) which is validated more than ever before and even acknowledged by the West in the wake of the present pandemic, time has dawned for us to rise once more as a resilient nation as we had done many a time before, drawing strength from the 'best Sri Lankan practices' which have stood the test of times and in the spirit of Buddha's words, sabbe saththa bhawanthu sukhithaththa or may all living beings be happy and free from suffering.

The multi-pronged solutions entailed in the teachings of Lord Buddha to enlighten us all during these turbulent times are many.

We spoke to Ven. (Prof.) Wijitapure Wimalaratana Thera, former Head of the Department of Economics, University of Colombo and the Vice President of the Sri Lanka Economic Association (SLEA) to reflect on them. 
Following are the excerpts:

Q: How does Buddhism explain and bring insights to the current plight of life and uncertainties while enabling the world to see things as they are?

A: Buddhism maintains that the cosmic principles or natural laws (Niyama) regulate everything in the universe including pandemics such as COVID-19. The natural laws are brought under five clusters as weather (Uthu Niyama), foods or seeds (Bija Niyama), actions (Kamma Niyama), mind or knowledge (Citta Niyama) and physical and spiritual matters (Dhamma Niyama).
The origin and the spread of the COVID-19 can also be analyzed applying those five laws. The widely accepted cause of the origin of the ongoing virus is the food consumption in Wuhan, China. Similarly, human actions, physical and spiritual matters, mind or knowledge and weather contributed to the spreading and also the successful management of the pandemic.

The good health (Nirogi) is highly appreciated (Arogyamada) in the Buddhist texts. The high life expectancy is considered as an important achievement in modern economic development indicators including the well-known Human Development Index (HDI) of the United Nations Development Programme (UNDP). The blessings for longevity (Ayurarogyasampaththi), absence from sufferings (Nidukkho), happiness stemming from good health (Nirogananda), and freedom from all illness (Sabba roga nivimuththo) are a few concepts visible in Buddhist texts.

The following verse highlighting the good health in Dhammapada (Verses of doctrine), a section of the Khuddaka Nikaya, is popular among the Buddhists in almost every country:

"Arogya parama labha-santhutti paramam dhanam vissasa parama nati- Nibbanamṃ paramamṃ sukhamṃ"

The English translation of the Pali verse renders as 'health is the ultimate profit, happiness is the ultimate wealth, a trusted friend is the best relative, Nibbana is the ultimate bliss. '

Q: How best can Sri Lanka be placed in this situation in the world map reflecting different kinds of maturity, considering the concept of discipline associated with the Buddhist philosophy?

A: The Sri Lankan government took early preventive measures with the consultation of several specialists from diverse disciplines, so that it was very successful at the beginning of the crisis. There was no resistance from people against the lockdown and other measures taken by the government. There have not been large social and religious gatherings after government announced of the coping mechanism against the pandemic. People were also ready to maintain the minimum consumption levels as ordinary supply chains had been broken or interrupted.

Dedication and spirit of the frontline workers have also been very high. They were not complaining of the minimum facilities they had in discharging their duties. This was a major plus point in implementing national level policies to address the unexpected problems created by the virus. Lord Buddha said that if someone cares for a sick person, he is the one who cares for the Buddha (Yo gilanam upateyya, somam upatteyya).

Donations have been flowing for needy people from the very beginning. Buddhist priests, different types of societies and individuals including those with moderate means were engaged in welfare activities for the needy. There was not a single report on starvation related deaths in our country. The public utilities such as water, electricity, gas, sewage, and telecommunication have been provided uninterruptedly up to this point of time.

The government has also provided a relief package in cash for needy households despite certain shortcomings of the programme. Generosity or charity (Dana) is the first among the ten royal virtues (Dasa Raja Dhamma). It says that the government has to look after the welfare of the needy people. This principle is practiced by the government of Sri Lanka.

Q: In what ways can the economics principles of Buddhism help us overcome this situation individually, at organizational and at national level?

A: The mainstream economics highlights that the modern free societies are driven by the maximization of utility (self-welfare, gains or happiness) either through increased production or consumption. It focuses on a society dominated by rational people with maximizing behavior. The center of gravity in such a society is consumerism and the economy is driven by this behavioural pattern with a huge social, spiritual, economic and environmental cost.

The locking down strategy of the country was only a second option to the administrators of free economies. Even people were agitating against the lockdown in some countries as they lose their free moment and consumerism practices. As we know some countries paid a huge cost as a result of this behaviour.

Buddhist economics challenge the self-interest maximization behaviour as it focuses on no-self (Anatta) principle and minimizing of sufferings while ensuring the wellbeing of all living beings and protecting the living environment.

The rational people of the mainstream economics concentrate on material wealth and income inspired by growing desire or avarice. Buddhism accepts needs of life such as clothes, food, shelter, health, education, transport etc. but it does not promote insatiable wants of life. Buddhism emphasizes sustainability and happiness of life rather than pusuing materials.

Q: How could we capitalize on the Buddhist philosophy in order to brave the challenges in the post-COVID era?

A: Society needs sustainable happiness through community participation. The rulers, community leaders, clergy as well as those who are affluent and privileged, should give examples to the ordinary masses through their daily behavioural patterns rather than preaching or making public speeches. A collective voice will reduce the cost of waste, corruption, mismanagement, over consumption and the breeding of poverty. The message of Buddhist texts should be a part of the practical life to achieve this noble goal.

The world experienced the influence of isolation, uncertainty, fear, anxiety and sudden departures of loved ones. The physical and mental implications of the COVID Virus will remain in the human society for a few generations.

The moral conduct of Buddhism is centered on the individual. Self- discipline is highly endorsed in Buddhism. Dhammapada endorses that 'good is restraint in deed; good is restraint in speech; good is restraint in mind; good is restraint in everything. The monk, restrained at all points, is freed from sorrow.'

Q: What are areas we should be focusing on in order to raise from this catastrophe as a nation?

A: There are a number of areas in this exercise including the health sector itself. Re-commencement of the economic activities which are currently at a standstill both at personal as well as national level, education, infrastructure development, social sector, tourism and international sectors, private sector issues of the country etc. should all be focused on.

Sri Lanka records a high literacy rate; it is just to read and write. Still many people do not have sufficient health literacy, economic literacy, and political literacy. Making good health related decisions are essential even after the COVID. There are so many issues relating to our consumption and behavioural patterns. The level of non-communicable diseases may have gone up as people are confined to their houses. Similarly, ordinary health services carried out by the public and private sector have been disrupted during this period of time, so that certain health related matters such as treatments, surgeries have been accumulated now. It is essential to clear up the accumulated cases as one cannot postpone health concerns unlike any other commitments.

The country has to initiate strategies to regain most of the micro, small and medium scale COVID affected enterprises. Similarly, large scale enterprises need certain strategies to bring them back to operational level. Economic stimulation packages are being introduced by many countries in addition to short term handouts to selected households. Sri Lanka should also prioritize the key economic sectors which generate more income, employment, government revenue and foreign exchange to the country.

Unemployment and poverty that the pandemic will entail will require expeditious channels to address them. Moreover, some of the Sri Lankan migrant workers are back in the country while many others are still waiting to come back. Their unexpected presence will aggravate not only the unemployment problem but also the decreasing foreign reserves of the country due to decline of foreign remittances. In addition to that, the Middle East job market is shrinking along with the unprecedented low global crude oil prices.

The biggest casualty would be the tourism sector in the country, so that industry specialists should formulate novel strategies to resurrect the main driver of the economy. There is a huge unexploited potential in the sector which can be exploited with the collaboration of local and global investors.

Q: What are the opportunities we will have in view of all the changes taking place around the world in terms of lifestyle, new thinking patterns and economic powers?

A: The world economic power will be shifting towards Asia, especially the East Asia led by China and to some extent by Japan and other regionally growing economies such as South Korea. It is widely accepted that this is the 'Asian Century' and the region will be generating more than fifty percent of the global income by the middle of this century. India is the economic power house in south Asia and some of the massive western companies are planning to invest more and more in India.

The western life style will not change markedly in the future even though COVID remains in the world for quite some time and consumerism society will be back on the track after sometime. Even though it is not the best economic system for the global sustainability in the future, Sri Lanka has to exploit her warranted opportunities in the global economy while emphasizing unutilized and underutilized resources of the country.

Subsistence economies or self-sufficient economies are outdated coins and no country will go back to the old system. However, many countries, at least in the short-run, will reformulate their economic policies to guarantee their pride and survival with the COVID experience they are faced with during this troubled time. When it comes to medical supplies, even the most advanced countries are facing difficulties in procuring certain essential items to run their health services smoothly.

Sri Lanka is heavily dependent on drugs and other related medical supplies from India, Pakistan and Bangladesh. The Health Ministry is the biggest importer of those items to maintain its free medical services in the country. Imports have been the long standing norm due to unexplained factors even though local private sector and the public sector is in a position to produce high quality medicine in the country. Now it is high time we promoted these products locally along with the other suitable products such as buses, railway compartments, and agricultural equipment with the support of local or overseas private sector rather than importing each and everything to the country.

The country is maintaining cordial relationships with many global economic power houses. The post COVID environment will provide global investors to reformulate their investment strategies. Sri Lanka is in a good position to exploit the emerging opportunities, if investor friendly environment is guaranteed. This will be a game changing opportunity for the country, if it is exploited prudently.

COVID has incidentally taught a lesson to Sri Lankan migrants and the diaspora that their country of origin is the best. It seems that some are contemplating their return either to live peacefully with their savings or to earn profits out of investments in the country. Sri Lanka has to guarantee a congenial atmosphere to attract them back to the country.

The Central Bank of Sri Lanka took a wise decision to attract foreign currency trough tax free Special Deposit Accounts (SDAs). When we mooted this strategy a few years ago, the official response was 'what to do with this money?' Depending on the availability of the quantity of foreign currencies, the country can go one more step further by allowing banks to invest in reliable international bonds.

Q: What are the unique strengths we have as country to be among the strongest in the emerging new post-COVID world?

A: We can exploit our strategic location, educated labour supply and untapped resources such as uncultivated lands in dry areas. The potential areas would be pharmaceuticals, high quality handlooms production in rural areas catering to unemployed women in rural areas. The migration dream of young people has been shattered by COVID to a great extent and such youth could be channelled towards employment in their own neighbourhoods if decent salaries are offered. It is also essential to introduce Professional Diploma Programmes with the participation of the private sector not only for industries but also for agriculture and other services.

Q: Finally, how can we change the Sri Lankan mind set from the survival mode to that of a growth mode to lead the others, from a Buddhist perspective?

A: The people of Sri Lankan had neither the ‘survival mind set’ nor the ‘dependent mind set’ well before political independence. The incumbent governments spoiled the mind set of people by introducing different types of universal welfare policies without targeting the qualified people for them. Within two-three decades, Sri Lankans developed the 'dependent mentality' described in literature as the 'dependency syndrome'.

Under native monarchs, ordinary people paid taxes either to the monarch himself or to the nobles appointed by him in addition to looking after family responsibilities by themselves. They did not have the expectations of government support and worked hard to build irrigation systems, temples, pagodas and other artistic master pieces.

Buddhism encourages hard work rather than dependency. The self-liberation can be achieved by one's own hard work. The minor collection (Khuddka Nikaya), the last of the five collections of Sutta Pitaka, describes ten noble qualities (ten perfections) associated with Bodhisatvas. The diligence (Viriya parami) is the fifth noble quality of Bodhisatvas. Similarly, the noble eightfold path, the path for ending the suffering of life and achievement of self-awakening, emphasizes the right livelihood. It says that ‘ do not earn your living by harming others, and do not seek happiness by making others unhappy.’

Coronavirus: Renowned Chinese scientist dubbed 'Bat Woman' warned of potential of COVID-19 pandemic

Coronavirus: Renowned Chinese scientist dubbed 'Bat Woman' warned of potential of COVID-19 pandemic

By 9News Staff
A Chinese scientist dubbed the 'Bat Woman of Wuhan' warned the public of a virus outbreak from bats up to 15 years prior to the COVID-19 pandemic.
Dr Shi Zenghli was the first to identify the gene sequence for COVID-19, having years of experience doing studies on viruses in bats and other animals.
In 2005, her research discovered that bats are the natural carrier of SARS-like coronaviruses, and in 2015 she predicted the devastation of such animal-borne viruses could have on humans in the modern world.
In the paper entitled 'A SARS-like cluster of circulating bat coronaviruses shows potential for human emergence' it was argued that SARS "heralded a new era in the cross-species transmission of severe respiratory illness with globalisation leading to rapid spread around the world and massive economic impact".
"Although public health measures were able to stop the SARS-CoV outbreak, recent metagenomics studies have identified sequences of closely related SARS-like viruses circulating in Chinese bat populations that may pose a future threat,'' the paper she co-authored with 14 other scientists stated.
In a TED Talk around the same time about viruses, she referenced her research in bat caves around Asia, and said the proximity of some bat colonies to animal farms and human settlements were causes for serious concern.
"Even though we have been looking for so many viruses for so many years, SARS didn't come back,'' she said.
"But in fact, in nature, these viruses similar to SARS.
"Actually it's still there.
"If we humans do not become vigilant, the next time the virus gets infected, either directly or through other animals. This possibility is entirely possible."
Recently Dr Shi has had to defend her and her teams' research in China into bat-borne viruses at the Centre for Emerging Infectious Diseases at the Wuhan Institute of Virology (WIV).
She is a key figure at the biosafety level 4 lab located in Jiangxia District, Wuhan, and is in the middle of international diplomatic tensions between the USA and China, accused of being at the centre of a 'government cover-up' about her findings into COVID-19.
Despite claims by conspiracy theorists and US President Donald Trump of the coronavirus being leaked accidentally or deliberately from a lab in Wuhan, numerous experts in the field have disputed this.
Scientists found that 66 per cent of the first cluster of 41 cases in Wuhan in December were linked to a wet market in the city.
In addition to this, the genetic sequencing proved that the new SARS-CoV-2 coronavirus did not match viruses sampled at the WIV.
Coronavirus: China’s diplomatic aggression on Australia
President of EcoHealth Alliance Peter Daszak called conspiracy theories like a lab leak of the virus as "preposterous".
"If you do the math on this, it's very straightforward. We have hundreds of millions of bats in Southeast Asia and about 10 per cent of bats in some colonies have viruses at any one time. So that's hundreds of thousands of bats every night with viruses," the disease ecologist told Vox.
"We also find tens of thousands of people in the wildlife trade, hunting and killing wildlife in China and Southeast Asia, and millions of people living in rural populations in Southeast Asia near bat caves.

"We went out and surveyed a population in Yunnan, China - we'd been to bat caves and found viruses that we thought could be high risk. So we sample people nearby, and 3 per cent had antibodies to those viruses.
"So between the last two and three years, those people were exposed to bat coronaviruses. If you extrapolate that population across the whole of Southeast Asia, it's 1 million to 7 million people a year getting infected by bat viruses.

"There are probably half a dozen people that do work in those [virus research] labs.
So let's compare 1 million to 7 million people a year to half a dozen people; it's just not logical."

අවාසනාවකට මෙන්, මේ මොහොත වන විට, රටේ වැඩිම ආසාදිතයන් ප‍්‍රමාණය මෙන්ම, වාහකයන් පිරිස බවට පත්ව සිටින්නෝ හමුදා සාමාජිකයෝය. ඒ අතර නාවික හමුදාවේ, විශේෂ බලකායේ, ගුවන් හමුදාවේ මෙන්ම යුද හමුදාවේද සාමාජිකයෝ සිටිති.

මේ තත්වයට අනුමාන කළ හැකි හේතු පැහැදිලිය. එකක්, නිසි සෞඛ්‍යාරක්‍ෂක ක‍්‍රම භාවිත කරන්නේ නැතිව, කෝවිඩ් 19 ආසාදිතයන් හා ආශි‍්‍රතයන් සමග සමීපව ඔවුන් කටයුතු කිරීමය. දෙක, ආසාදිතයන් හා ආශ‍්‍රිතයන් සමග කටයුතු කළ හමුදා සාමාජිකයන් ඔවුන්ගේ නේවාසික කඳවුරු තුළට ගැනීමේදී නිසි සෞඛ්‍යාරක්‍ෂක පිළිවෙත් නොසලකා කටයුතු කිරීමය. තුන, කඳවුරු තුළදී, වයිරසය එකකුගෙන් අනෙකකුට සම්පේ‍්‍රෂණය වීමෙන් වැළකීමේ ආරක්‍ෂිත ක‍්‍රමවේද නිසි භාවිතයට නොගැනීමය. විශේෂයෙන්, වයිරසය ආසාදිත හා ආශ‍්‍රිත පිරිස සමග ගනුදෙනු කර, නැවත කඳවුර වෙත පැමිණි පිරිස, කඳවුර තුළදී අනුගමනය කළ යුතු සෞඛ්‍යාරක්‍ෂක ක‍්‍රමවේද භාවිත කෙළේද යන්න සොයා බැලිය යුතුය. හතර, එවැනි හමුදා සාමාජිකයන් අනිවාර්යයෙන්ම යටත් කළ යුතු වයිරස ආසාදනය වීම පිළිබඳ දෛනිකව පරීක්‍ෂණ නොකිරීමය. එසේ විණි නම්, යම් අවදානමක් හටගැනෙන අවස්ථාවකදී වහාම හඳුනාගැනීමට ඉඩ තිබිණ. පහ, එවැනි අවදානමක සිටින හමුදා සාමාජිකයන්ට, නිවාඩු ලබා රිසි සේ නිවෙස්වලට යාමටත්, නිවෙස් ආශ‍්‍රිතව හා පිටත නිදහසේ හැසිරීමටත් අවස්ථාව දී තිබීමය.

මේ කිසිවක් ආසාදිත හමුදා සාමාජිකයන්ගේ වැරදි නොවේ. ඔවුන් කර ඇත්තේ ඉහළින් තමන්ට එන අණ ක‍්‍රියාත්මක කරමින් රාජකාරිවල යෙදීමය. තමන්ට සෞඛ්‍යාරක්‍ෂක ඇඳුම් හා උපකරණ අවශ්‍යදැයි සමහර විට ඔවුන් නොදැන සිටින්නට ඇති අතර, දැන සිටියත්, ඒවා නැතිව රාජකාරි කරන්නට නියම වූ විට වුණත්, ඊට එරෙහි වන්නට ඔවුන්ට අයිතියක්, අවකාශයක් නැත.

කෙටියෙන් කිවහොත්, වසංගත රෝගීන් සමග මුළුමනින්ම අවදානම් පසුබිමක, මුහුණට මුහුණ ලා කටයුතු කරන වෛද්‍ය, හෙද හා අනෙකුත් සෞඛ්‍ය අංශවල සාමාජිකයන්, වසංගතය මැඞීමේ තීරණාත්මක වැඩකොටසක් නොකරන්නේද යන පැනය සාමාන්‍ය මිනිසුන් තුළ පවා පැනනැගෙන්නට මේ මවාපෑම් හේතුවන්නට ඇත. 
වසගංතය මර්දන ක‍්‍රියාවලිය ඒ ගැන දන්නා වෛද්‍ය හා අනෙකුත් විශේෂඥයන්ට මුල්තැන දී ඔවුන්ගේ උපදෙස් අනුව කරනවා වෙනුවට හමුදාවේ මූලිකත්වයෙන් කරන බවක් පිටතට පෙනීගියේය.


එහි උපාය මාර්ගය පැහැදිලිය. යුද්ධය ජයගත්තාක් මෙන්ම, හමුදාව යොදවා කෝවිඩ් වසංගතයත් අපි ජයගත්තෙමුය යන්න මහමැතිවරණයට ආයෝජනය කිරීමත්, මිලිටරියට බර තබන අධිකාරවාදී පාලනයක් පවත්වාගෙන යෑම සඳහා තල්ලූවක් ලබාගැනිමත්ය.


එහෙත්, දැන් මතුවන අවාසනාවන්ත තත්ත්වය නම්, හමුදාව ඒ අවදානම් කාර්යයන් සඳහා යොදවා ඇත්තේ නිසි පරිදි සෞඛ්‍යාරක්‍ෂක උපක‍්‍රම හා පහසුකම් ඔවුන්ට ලබාදෙන්නේ නැතිවය යන්නයි. එයින් අවදානමට ලක්වුණු ඒ පිරිසට, හිතුමගේ නිවෙස්වලට යන්නටද ඉඩදීමෙන්, රට පුරා අවදානමක් ජනිත කිරීමට ඉඩකඩ සලසා දෙන ලද බවද පෙනේ.

එහෙත් වසංගතයක් සම්බන්ධයෙන් එසේ නොවේ. ආයුධ ප‍්‍රහාරවලින් වසංගතයක් මැඬපැවැත්විය නොහැකිවා පමණක් නොව, කිසිවකු නොදැකම විෂබීජ තමන්ගේ ශරීරයේ එල්ලෙන්නට පිළිවන. එය තේරුම් ගැනීමට, යුද්ධයේදී දෙන පුහුණුව ලබාදී වසංගතය ඉදිරියට පැමිණවූ හමුදා සාමාජිකයන්ට නොහැකිය. එය වෙනම විiාවකි. එවැනි මෙහෙයුමකට යන විට, ඇසට පෙනෙන සතුරකු ගැන නොව, ඊටත් වඩා භයානක නොපෙනෙන සතුරකු ගැන සිතා ඊට ගැළපෙන ලෙස ආයුධවලින් නොව, සෞඛ්‍යාරක්‍ෂිත ක‍්‍රමවලින් සන්නද්ධව යා යුතුය.

Would you pay more money and go the Extra Mile or is it pain in the neck?


Would you pay more money and go the Extra Mile or is it pain in the neck?

There is so much hype about Windows 7 and on my daughter’s request I went and bought a Windows 7 Starter Pack but kept on delaying opening of the pack to install it since the netbook I bought her already had Windows XP.
She has a working knowledge of Linux with  the desktop she had and I bought the netbook stating that if it started giving problems she has to go back to Linux for her work.
Something simple like Lubuntu or Meego or something advanced like Sabayon, PClinux or Mepis or even Debian.
Then I wanted to repartition (re-size) the hard disk but the XP installed did not allow me to repartition unless I delete the operating system with it.
Since I have paid for the operating system, I realized it is not a wise thing to do since if she wants there are enough computers at home to try Linux including her desktop.
Then everything went into cold storage and she was down with some illness and Windows 7 was completely forgotten.
Today as part of my full reformatting exercise, I deleted all my partition and booted this Windows 7 Starter Pack to see what it has.
It immediately recognized the 20 GiB ntfs partition  (I made as an extra storage facility), the hard disk had and it started giving me instruction that it can be installed in one computer only and the blah blah.
I pulled out the Internet wire fearing it is going to note my laptop machine number and the details and it’s identity and then allowed it to install.
Mind you this was the computer I bought in Singapore after a big fight with the vendor stating that I did not want windows installed in it and I only want the machine and I know what to do with it.
Then I booted Linux while waiting in lounge of the Changi Airport with Linux DVD I downloaded in Singapore (in one of my relative’s residence in Singapore).
After installing it goes up several times rebooting and this is the time it gives all your details to the Microsoft head quarters to subsequently send warning after warnings to lure you to buy all the extra utilities.
Finally it booted up and this one lets you have a password facility and the system has nothing at all to work with.
I told my daughter how stupid was to buy it and booted up and showed her the latest 10th anniversary Knoppix 6.4 live with compiz graphic and Pingus game in it and amazingly beautiful graphics.
It has enlightenment effects and LibreOffice and over 6000 t0 10,000 packages in it’s DVD.
Who is stupid Microsoft or little Me I will let you decide it.
Mind you I installed Knoppix and Sabayon KDE while typing this bloggy blog and tested PCLinuxfullmonty has 64 bits capability also, in between watching the last stages of the Sri-Lanka New Zealand cricket match too.
I must tell you Win 7 took a longer time to install and restarted several times.
Sabayon has a media center called XBMC and it is something windows users will never have the luxury of using.
PCLinuxfullmonty has blender and with these three distributions in my laptop I have amazing rich collection of graphic utilities.
I did not have to pay a red cent but had to spend some time downloading the 3 DVDs with K-Torrent.
Only limitation was the slow download speed of Sri-Lankan Telecom.

Abolishing the Post of Presidency in Ceylon

Abolishing the Post of Presidency in Ceylon
Time has come to review the need of a post of Presidency.
The framers of the current (even the past constitution left gaping holes) constitution have failed to see an epidemic of current level will make the holder of this post becoming a dictator rather than a facilitator.
In actual fact, a military dictatorship as opposed to police state.
Luckily the police has kept the army at bay (they are under civil service control in the past, under British) due to current necessities.
Healthy rivalry of the police and army is essential for a working democracy whereas the Army follows orders from higher up who can become somebody like Idi Amin or guys in Myanmar with ethnic cleansing.
This post was impotent in some sense and MS (previous holder)  showed the dissociation with consensual agreement albeit mildly.
Current one wants the parliament to be impotent till his cohort's (not in any way with consensus with the opposition parties) agenda is converted to practice.
The election Commission is dilly dallying with the constitution but the life of an average daily earner is in the balance (by holding the election on top of a economic crisis).
Money saved by delaying the election can be utilized for essential workers with protective gear (including civil servants conducting the election) that is in short supply already.
I think, a mature lawyer or a sensible citizen should go to courts and display that there is potential for disaster waiting to unfold and  an election catastrophe.
Current parliament has the validity well beyond, if consensus is reached by summoning the parliament.

The dictators have the affliction of listening to nobody or the opposing logic.

One stupid guy comparing the pandemic to Dengue (medical term is epidemic with rainfall)  is illogical and he has gone nuts by power hunger.
The coronavirus will become an endemic for few years if the lockdown is broken an election is held.

Example is what happened to navy guys who have a particular sexual orientation. 
It is endemic in camps.
Police personnel are  saved simply because police service is essentially decentralized.
But even they are not immune.
Even Prime Ministers (UK) and Speakers (Pakistan) are affected.
Any large gathering at Prime Ministers residence is a major risk.
I think the Prime Minister wants opposition members to get sick.
Why can't they hold a video conference.
If they do not have these facilities let the money saved (delaying election) be used to acquire them in double quick time.
I congratulate JVP for boycotting the invitation.
They should be very critical of the militarization.
They have suffered thrice under military suppression, and knows how bad it is. 
My gut feeling is by holding the election virus will get a foothold and our health service will be permanently paralyzed and we won't be able to run our basic immunization program for our mothers and children.

Is Coronavirus spread more prevalent among homosexuals?




Is Coronavirus spread more prevalent among homosexuals?
My question is pertinent, since a lot of guys/girls including teachers, principles, tuition masters, priests, monks and politicians prey on under age children.
One Prime Minister of England of my time was sleeping with a child while holding office and his cohorts on both parties and journalists hid this fact.
I was trained in UK to catch the culprits and my last case was a UK police officer and I sent his pubic hair for genetic confirmation.
They (including the consort) vouched that the hair belonged to the dog.
My consultant (an Indian) did (suffice is to say, he got into trouble) did not confirm my findings that night itself and that night I resigned from my post and returned home with the first available flight, never to return to UK.
Before I left a female Prime Minister made homosexuality of consenting adults, legal in UK.
I recorded every (I was trained in pathology in Ceylon before I started migrating to Paediatrics) detail in a tiny O.P.D card just, enough for courts requirements in a future date.
Back at home in private practice I collected ample evidence of paedophilia and traced them to a care home run by a Swedish guy.
I intimated (not the true records) this to a incredible female politician holding high office with two young kids.
She allowed this guy to go scot free and her explanation was that we would lose tourist income.
Now my concern here not only epidemiology buts its mode of spread.
The authorities are slow to accept that it is an enterovirus, just like hepatitis B virus (DNA virus) with a long incubation period.
It has respiratory mode of spread too.
Coming back to AIDS (retrovirus) virus, it was transmitted by German servicemen working on kidneys of a particular tree monkey.
These Germen servicemen were homosexuals (African kids) and I guess they were even sodomites and bastards.
It is interesting that a particular group of our servicemen spread this disease in tandem with militarization of our body politics.

Professional Responsibility

Professional Responsibility

Sweden’s approach is stupid to say the least (provided it did not take simple precautions, stated below) even disregarding the high death toll in Sweden.

One epidemiologist acting without data is shear madness and subtle medical dictatorship.

I need few basic data.
Is it an enteric virus?
Is it a respiratory virus?
Is the mode of transmission a combination of the two?
What is the gap period (I.C.P.) between the two?
 
In other words the total incubation period assuming the enteric phase was missed or callously disregard.
 
We haven’t got the data due to lying and conniving of China and WHO.

There are a lot to blame including guys and girls in Ceylon.

Simple sanitation methods (adapted in West Africa during Ebola virus endemic) like hand washing, wearing gloves, masks and gowns are neglected world wide especially in Indian subcontinent and Africa. 
 
Social distancing even though difficult to practice  in the East (assuming respiratory mode of transmission) was outstandingly successful in the West (associated with the level of education and social responsibility).

   

One can be smart after the fact and the moment I got the wind of it without telling anybody, I /we kept at home for two months (wife joined) long before WHO and Ceylon recommendations.

 

By the time warning bells were rung, the  horse had bolted from the stable.

  Friedman: 

Is Sweden getting it right with its…

President Donald Trump has often described this pandemic as our “war” with an “invisible enemy” — the coronavirus. 
That war metaphor is wrong and misleading.
Wars are fought and won by humans. 
But when you’re in a struggle with one of Mother Nature’s challenges — like a virus or a climate change — the goal is not to defeat her. 
No one can. 
She’s just chemistry, biology and physics. 
The goal is to adapt.
 
Mother Nature does not reward the strongest or the smartest. 
 
She rewards the species that are the most adaptive in evolving the chemistry, biology and physics that she has endowed them with to thrive — no matter what she throws at them.
And that’s why I believe one of the most important questions we need to answer, as these lockdowns end, is this: 
Are we going to adapt to the coronavirus —by design— the way Sweden is attempting to do — or are we going to go the same direction as Sweden —by messy default— or are we just going to say “the hell with lockdowns” and go 50 different ways?
In case you’ve missed it, Sweden has taken a radically different approach in dealing with the coronavirus. It has essentially opted for a strategy of “herd immunity” through exposure.
This strategy posits that most people under age 65 who get the coronavirus — if they do not have major preexisting medical conditions — will either experience it as a typical or tough flu, or completely asymptomatically, and the number who will get so sick that they require hospitalization or emergency care will reliably be less than the number of beds needed to care for them.
So, if you do your best to shelter and sequester all of those over 65 and those with serious preexisting conditions — notably heart and lung disease and diabetes — and let much of the rest of the population circulate and get exposed and become naturally immune, once about 60% of your population has gone through this you’ll have herd immunity and the viral transmission will be blocked. (This assumes that immunity for some period of time results from exposure, as most experts think it will.)
After all, herd immunity is our goal — either from vaccination or from enough people building natural immunity. Those are the only ways to achieve it.
The upside of Sweden’s strategy — if it works — is that your economy does not take such a deep hit from lockdowns.
 
Anders Tegnell, chief epidemiologist at Sweden’s Public Health Agency — the nation’s top infectious disease official and architect of Sweden’s coronavirus response — said in an interview published in USA Today on Tuesday: “We think that up to 25% people in Stockholm have been exposed to coronavirus and are possibly immune. A recent survey from one of our hospitals in Stockholm found that 27% of staff there are immune. We could reach herd immunity in Stockholm within a matter of weeks.”
It has come with a high cost, though. As USA Today noted: “As of April 28, (Sweden’s) COVID-19 death toll reached 2,274, about five times higher than in Denmark and 11 times higher than in Norway.”
Here’s the stone-cold truth: There are only different hellish ways to adapt to a pandemic and save both lives and livelihoods. I raise Sweden not because I think it has found the magic balance — it is way too soon to tell — but because I think we should be debating all the different ways and costs of acquiring immunity.
When I look across America, though, and see governors partly lifting lockdowns — because they feel their people just can’t take it anymore for economic or psychological reasons, even though their populations have little or no immunity — I worry we may end up developing more herd immunity but in a painful, deadly, costly, uncoordinated way that still leaves room for the coronavirus to strike hard again and overwhelm hospitals.
Herd immunity “has historically been nature’s way of ending pandemics,” added Dr. David Katz, the public health physician who helped kick off the debate in an essay he wrote in The New York Times on March 20 and in a follow-up interview we did together.
“We need to bend with her forces — even when we as a species are responsible for unleashing them,” Katz said. That means a designed strategy, based on risk profiles, of phasing back to work those least vulnerable, so we gradually cultivate the protection of herd immunity — “while concentrating our health services and social services on protecting those most vulnerable” until we can sound the all-clear.
Thomas L. Friedman is a New York Times columnist.

This is an extremely important (and also entertaining) book that should be mandatory reading not just for anybody interested in finding out about what data-driven medical studies really mean, but also for anybody engaged in any kind of empirical work. What Kendrick shows brilliantly is the extent to which the vast majority of medical recommendations and guidelines are based on data-driven studies that are fundamentally flawed and often corrupt.
He highlights how the resulting recommendations and guidelines have led (world-wide) to millions of unnecessarily early deaths, millions of people suffering unnecessary pain, and widespread use of drugs and treatments that do more harm than good (example: statins), as well as wasting billions of taxpayer dollars every year.
As researchers who have been involved in empirical studies in a very wide range of disciplines over many years we believe that much of what he says is also relevant to all of these disciplines (which include most branches of the physical, natural and environmental sciences, computer science, the social sciences, and law).
Apart from the cases of deliberate corruption and bias (of which Kendrick provides many medical examples) most of the flaws boil down to a basic misunderstanding of statistics, probability and the scientific method.
There are two notable quotes that Kendrick uses, which we believe sum up most of the problems he identifies:
  1. “When a man finds a conclusion agreeable, he accepts it without argument, but when he finds it disagreeable, he will bring against it all the forces of logic and reason” Thucydides.
  2. “I know that most men, including those at ease with problems of the greatest complexity, can seldom accept even the simplest and most obvious truth if it be such as would oblige them to admit the falsity of conclusions which they have delighted in explaining to colleagues, which they have proudly taught to others, and which they have woven, thread by thread, into the fabric of their lives.” Leo Tolstoy
The first sums up the extent to which results of empirical work are doctored to suit the pre-conceived biases and hopes of those undertaking it (a phenomenon also known as ‘confirmation bias’).
The second sums up the extent to which there are ideas that represent the ‘accepted orthodoxy’ in most disciplines that are impossible to challenge even when they are wrong. Those brave enough to challenge the accepted orthodoxy risk ruining their careers in their discipline.
Hence, most researchers and practitioners simply accept the orthodoxy without question and help perpetuate flawed or useless ideas in order to get funding and progress their careers. Kendrick describes how these problems lie at the heart of the fundamentally fraudulent peer review system in medicine – which applies to both submitting articles to journals and submitting research grant applications. Once again, we believe that all of the areas of research where we have worked (maths, computer science, forensics, law, and AI) suffer from the same flawed peer review system.
Kendrick is not afraid to challenge the leading figures in medicine, often exposing examples of hypocrisy and corruption. Of special interest to us, however, is that he also challenges the attitude of revered figures in our own discipline. For example, Kendrick highlights two quotes in a recent article by Nobel prize-winner Daniel Kahneman, whose work in the psychology of decision theory and risk is held in the highest esteem.:
  1. “The way scientists try to convince people is hopeless because they present evidence, figures, tables, arguments, and so on. But that’s not how to convince people. People aren’t convinced by arguments, they don’t believe conclusions because they believe in the arguments that they read in favour of them. They’re convinced because they read or hear the conclusions from people they trust.
    You trust someone and you believe what they say.
    That’s how ideas are communicated.
    The arguments come later.”
  2. “Why do I believe global warming is happening?
    The answer isn’t that I have gone through all the arguments and analyzed the evidence – because I haven’t. I believe the experts from the Academy of Sciences. We all have to rely on experts.”
Kendrick notes the problem here:
“In one breath he states that people aren’t convinced by arguments; they’re convinced because they read or hear conclusions from people they trust. Then he says that we all have to rely on experts. But he does not link these two thoughts together to ask the obvious question.
Just how, exactly, did the experts come to their conclusions?”
Having presented the BBC documentary on Climate Change by Numbers we also got an insight into the extent to which problems exist there.
As good as the book is (and indeed because of how good it is), we feel the need to highlight some points where we believe Kendrick gets it wrong.
There are some statistical/probability errors and over-simplifications, which mostly seem to stem from a lack of awareness of Bayesian probability. For example, he says:
“… although association cannot prove causation, a lack of association does disprove causation”.
This is not true as can be proven by the simple counter example we provide below using a Bayesian network.
Next we believe Kendrick’s faith in randomized control trials (RCTs) as being the (only) reliable empirical basis for medical decision making is misplaced. Because of Simpson’s paradox and the impossibility of accounting for all confounding variables there is, in principle, no solid basis for believing that the result of any RCT is ‘correct’. As is shown in the article here it is possible, for example, that an RCT can find a drug to be effective compared to a placebo in every possible categorization of trial participants, yet the addition of a single confounding variable can result in an exact reversal of the results.
So, if we are saying that even RCTs cannot be accepted as valid empirical evidence, does that mean that we are even more pessimistic than Kendrick about the possibility of any useful empirical research?
No - and this brings us to our final major area of disagreement with Kendrick’s thesis. In contrast to what Kendrick proposes we believe there is an important role for expert judgment in critical decision-making.
In fact, we believe expert judgment is inevitable even if every attempt is made to remove it from an empirical study (it is, for example, impossible to remove expert judgment from the very problem of framing the study and choosing the variables and data to collect).
Given the inevitability of expert judgment, we feel it should be made obvious, transparent, and open to refutation by experiment. Any scientist should be as open and honest about their judgment as possible and be prepared to make predictions and be contradicted by data.
By combining expert judgment with data it is possible to get far more reliable empirical results with much less data and effort than required for an RCT. This is essentially what we proposed in our book and which is being further developed in the EU project Bayes Knowledge.


Refuting the assertion “If there is no association (correlation) then there cannot be causation”.
Consider the two hypotheses:
  • H1: “If there is no association (correlation) then there cannot be causation”.
  • H2: “If there is causation there must be association (correlation).
Kendrick’s assertion (H1) is, of course, equivalent to H2. We can disprove H2 with a simple counter-example using two Boolean variables a, and b, i.e. whose states are True or False. We do this by introducing a third, latent, unobserved Boolean variable c. Specifically we define the relationship between a,b, and c via the following Bayesian network :

Doctoring Data in Ceylon




Doctoring Data in Ceylon

Evidence Based Surveillance is only way forward.

Data Massaging and Doctoring Data have come into operation in Ceylon.
Our election commission has no teeth to avoid this sinister ploy by the tricksters in temporary power.

There is ample evidence now, slowly by surely the Army is operating its own political agenda for a TINY subset of politicians.

They are willing to sacrifice their career for Ceylon Corona Covid and Crumbs (C.C.C.C.C) Company and expecting posts abroad with early retirement by passing the veteran civil servants.

But all the countries are closing their doors for these guys especially because, they are the ones who would carry the virus by plane loads.

Their dreams will come empty.


Our Health Department guys and girls would become (already it is happening behind doors) victims.

They are doctoring data without doing adequate surveillance studies.

They pick and choose where to test.

It is not a randomized sample but a political sample.

I believe every corner of the country should by sampled.

That means service sector guys, including farmers, drivers and conductors of trains and buses.

Secularizing sectors not cohorts is they way of doctoring data.

Data massaging is done by the TV or Media guys without epidemiological understanding of the basic challenge.

Charts can Cheat!

Data can hoodwink!


Specificity and sensitivity less than 90% would help data mining guys to spin and our “Spin Doctors” by holding election we can stop the spread of the disease.
Our public servants taking part in the election process will end up becoming Corona Careers.
Conona Virus will hoodwink statistics and would bypass the selective numbers.

In my assessment every positive data there are 10 to 20 hidden or Sacrificed DATA and Data Points.

We are playing with fire.

Early Election will add fuels to the fire.

The Election Commission should not hide behind statutory requirements but act with Common Sense and Gut Feelings.
How come three bothers of the Local Mafia Clan is spearheading the economic wind mills, just like “Helping Hambantota Scam” but by a wider margin.

Events in Evolution


Events in Evolution
In its 4.6 billion years circling the sun, the Earth has harbored an increasing diversity of life forms:
  • for the last 3.6 billion years, simple cells (prokaryotes);
  • for the last 3.4 billion years, cyanobacteria performing photosynthesis;
  • for the last 2 billion years, complex cells (eukaryotes);
  • for the last 1 billion years, multicellular life;
  • for the last 600 million years, simple animals;
  • for the last 550 million years, bilaterians, animals with a front and a back; 

  • for the last 500 million years, fish and proto-amphibians; 

  • for the last 475 million years, land plants;
  • for the last 400 million years, insects and seeds; 

  • for the last 360 million years, amphibians;
     
  • for the last 300 million years, reptiles; 

  • for the last 200 million years, mammals; 
     
  • for the last 150 million years, birds;
  • for the last 130 million years, flowers; 

  • for the last 60 million years, the primates, 

  • for the last 20 million years, the family Hominidae (great apes);

  • for the last 2.5 million years, the genus Homo (human predecessors);

  • for the last 200,000 years, anatomically modern humans.
Periodic extinctions have temporarily reduced diversity, eliminating:
  • 2.4 billion years ago, many obligate anaerobes, in the oxygen catastrophe; 

  • 252 million years ago, the trilobites, in the Permian–Triassic extinction event; 

  • 66 million years ago, the pterosaurs and nonavian dinosaurs, in the Cretaceous–Paleogene extinction event.
Dates are approximate.
