On this last Sunday of 2019, I wish every Hong Kong citizen a warm, peaceful and hopeful year 2020.

A New Year holds welcome promises of a fresh start and a new beginning. The New Year is also traditionally a time for planning, greeting, reminiscing as well as some soul and heart searching.

I believe that many of you would share my feeling that the year 2019 has been a year of unremitting shocks and turbulence to our community and our economy. Indeed, it has been a severely testing time for all in Hong Kong.

It all began with the introduction into the Legislative Council of the bill to amend the Fugitive Offenders Ordinance in April. Responding to strong public sentiment, the Government suspended all work on the bill in mid-June and declared its death in early July. On September 4, the Chief Executive announced the bill's withdrawal. This was done on October 23 when the Legislative Council resumed normal business.

Despite this, the public protests which began as largely peaceful and orderly marches in June soon got out of control. Unprecedented violence and reckless destruction became the norm. Radical protesters attacked police officers as well as police stations and facilities with petrol bombs, iron bars, bricks and chemicals. Some even used high-tension slingshots, bows and arrows. During the past six months or so, over 2,600 people were injured in the social unrest, including over 500 police officers.

Meanwhile, public infrastructure and transport including a cumulative total of 85 heavy rail stations and 62 light rail stations, as well as countless shops, restaurants and shopping malls had been repeatedly vandalised. More so, nearly 21,000 square metres of paving blocks from footpaths were ripped up and used as weapons to attack Police. Over 52,000 metres of roadside railing were removed and 740 sets of traffic lights destroyed.

Last month, masked protesters battered the Hung Hom Cross-Harbour Tunnel, shutting it down for two full weeks. This vital city artery normally carries 110,000 vehicles a day, accounting for some 43% of the daily cross-harbour vehicular flow. It took a total of 800 government staff and contractor's workers some 100 hours to carry out emergency repair round-the-clock before the tunnel could be reopened. At the same time, nearby Polytechnic University was overrun by radical protesters. The same happened to the Chinese University.

Apart from recklessly damaging our universities, violent protesters turned the two campuses into arsenals on a frightening scale. When the last of the protesters finally left the universities, Police seized altogether nearly 8,000 petrol bombs plus numerous explosives, hundreds of bottles of corrosive liquid and weapons of all sorts.

This level of premeditated and organised destruction and violence could hardly be tolerated in any country or economy that upholds the rule of law. Hong Kong, I am proud to say, is among those economies that believe passionately in the primacy of rule of law. It safeguards our economy, our community, our families and our way of life.

In fact, the rule of law is among Hong Kong's much cherished core values, alongside our fiercely independent judiciary, clean government, level playing field for business and enviable freedoms. These freedoms, as enshrined in the Basic Law and the Hong Kong Bill of Rights Ordinance, include freedom of speech, of the press and free flow of information; freedom of association and assembly; free trade and free port; free flow of capital; freely convertible currency; freedom of religious belief and free education. We have also been the freest economy in the world continuously for 25 years. The unique "one country, two systems" formula has been functioning well and we enjoy the best of both worlds.

Despite the recent social unrest which has affected our economy and labour market, Hong Kong's institutional strengths remain robust and intact. Our fundamentals stay sound and strong. We still enjoy a high rating in various areas by international think tanks and agencies. Allow me to say that whilst Hong Kong may not have the full semblance of Western democracy, we do enjoy for a very long time the full substance of real freedom which underpins Hong Kong's success.

Over the past six months, most of the requests for public meetings, processions and protests were given the greenlight by Police. During these public events, be it small or large, Police had dutifully facilitated and ensured the safety of protesters and other road users. When the requests were not approved, it was generally a decision made in the hopes of preventing violence, ensuring peace and public order, as our society has every right to expect of its police and its government.

On November 24, we witnessed a peaceful and orderly District Council Election with a record high turnout and voting rates. My colleagues and I are looking forward to working with all new District Council members. We also look forward to expanding our dialogue with the community. While we will continue to engage different sectors of society through our usual channels, the Government will broaden and rejuvenate our communication with the public. Less than two weeks ago and after the one by the Chief Executive in September, my Principal Official colleagues have started a dialogue with the public through Facebook live. You will certainly see more of us listening and responding to people's views and concerns on these and other communication channels in the coming year.

We are also establishing an Independent Review Committee comprising experts and community leaders. The committee will look into the causes and full circumstances of the social unrest and probe into Hong Kong's deep-seated social conflicts, from affordable housing, land supply, wealth gap, upward social mobility and opportunities for our young people to social justice. The committee will recommend ways to address the real and long-entrenched community concerns that underlie the discord.

Meanwhile, our economy is inevitably affected by the twin blows of social unrest and the trade dispute between the United States and the Mainland. Businesses and people of Hong Kong are yearning for the restoration of peace and order soonest possible, and the recovery of our economy.

In response, the Government has launched four rounds of relief measures since August. These added up to more than $25 billion. A number of the measures which will benefit grassroots families and small and medium enterprises will be implemented at the beginning of the New Year.

These relief measures would not solve our economic problems. Yet, they could help businesses and people of Hong Kong stay afloat while we strive to heal our divided community and battered economy.

There are deep-seated issues that we must acknowledge and resolve if we are to end the prolonged social unrest that has shaken the familiar Hong Kong which we all love and cherish. We must be patient and perseverant in helping our city to heal, one step at a time.

The past six months have been tough for us, but we will soldier on. Hong Kong is a remarkably resilient and resourceful international city with a strong can-do spirit. We have a New Year waiting for us. We have new and expanded channels of communication opened up for us. We expect the first report of the Independent Police Complaints Council to come out soon. And we have research and concrete recommendations of the Independent Review Committee ahead of us. Working together, I am confident that we can rebuild, reclaim and rejuvenate the remarkably resilient spirit of Hong Kong.

On this note, I wish all of you a New Year blessed with peace, harmony and goodwill.

Chief Secretary Matthew Cheung gave these remarks on RTHK's "Letter to Hong Kong" programme aired on December 29.

As we all know, Hong Kong as well as most parts of the world are facing a pandemic that has an enormous negative impact on our social and economic life. At this juncture, we don't have any accurate way to predict what will happen in the coming months. Two months ago, we were worried about whether COVID-19 would become a pandemic. Yet, the scale of the pandemic as we see now is not what we could have imagined two months ago. What we can do now is tackle the social and economic crisis upfront and build the resilience of our society, in particular, our employment market, so that when the time comes where social and economic activities can resume no matter how gradually or rapidly, our society can bounce back as soon as possible.

Unemployment has edged up bit by bit since the latter part of 2019. Statistics and daily news about business closures are telling us that unemployment is going up rapidly. While we should see what can be done to help those unemployed, the more important and urgent task is to see how we can "stop the bleeding", which essentially means job retention. The Employment Support Scheme, with a budget of over $80 billion, is designed exactly for that purpose. Through providing time-limited financial support, the whole idea of this scheme is to preserve jobs by enabling employers to keep their employees in employment for the coming months, and also when business resumes, employers can immediately grab the opportunities.

The central idea of the Employment Support Scheme is to provide wage subsidy that is equivalent to 50% of the wages of the employees up to a wage cap of $18,000 per month. The subsidy is given to the employers so that they can keep their staff for the coming six months. The employers will be required to have no redundancy or layoffs during the months that they receive wage subsidies from the Government.

In Hong Kong, we do not have a pay-as-you-go income tax system. Neither do we have a social insurance system nor a central provident fund to cover everyone in our workforce. That means we do not have any existing system covering every employer and employee in Hong Kong that we can devise a wage subsidy scheme that covers everyone. Any system meant to cover everyone in our workforce must be mandatory in nature and that will take time for us to have the relevant legislation in place and subsequently the system built.

However, schemes under the Mandatory Provident Fund (MPF) and the other Occupational Retirement Schemes provide a framework that we can develop a wage subsidy scheme to cover the great majority of the workforce. This is definitely not sufficient. In particular, we have identified three sectors that do not have good coverage in the provident fund systems. They are the catering industry, the construction industry and the passenger transport sector. Under the Anti-epidemic Fund, we have three sector-specific schemes to assist the employers and the employees in these sectors.

Many freelance workers or those in the so-called slash economy do not make contributions to the MPF. Though we have over 200,000 self-employed persons having an account in the MPF system, they do not pay MPF regularly. While we will provide a one-off wage subsidy to those self-employed persons who have made MPF contributions within the past 15 months, we also have three separate but mutually exclusive schemes operating under the Home Affairs Bureau, the Education Bureau and the Social Welfare Department, providing the same one-off wage subsidy to those freelance workers who provide arts and sports training. The one-off wage subsidy is $7,500.

Though all the schemes I mentioned above still cannot cover everyone in the workforce, this is the best we can do in making use of existing systems so that we can launch this round of the Anti-epidemic Fund in the shortest possible time to help our employers and employees to survive the challenges that are with us now. Any new systems to be built from scratch will not be able to provide the necessary timely support that employers and employees desperately need.

As mentioned earlier, unemployment is increasing at a disturbing rate. The basic unemployment protection system in Hong Kong relies on two legs. One is the Severance Payment or Long Service Payment payable by the employers, which is equivalent to two-thirds of the monthly salary times the number of years of service with the employer. The other is the Comprehensive Social Security Assistance (CSSA) Scheme. The CSSA provides a level of income support to families for their basic level of living in the context of Hong Kong. The CSSA provides a safety net to any family not having sufficient means, including those who are unemployed.

Apart from the income test, the CSSA also has an asset test. For the purpose of providing extra help to those unemployed during this difficult time, the Government will double the existing asset limit for the able-bodied for a limited period of six months, allowing more families with people unemployed to become eligible to receive CSSA. We estimated that about 40,000 families will benefit from this enhancement.

Unfortunately, over the years there is a social stigma towards the CSSA system. People in desperation may be deterred from applying for CSSA simply because of the stigma. This is the time for us to destigmatise the CSSA system. It is the safety net for citizens of Hong Kong. It is the responsibility of an affluent society like Hong Kong to provide the basic level of living to those who cannot afford to do so on their own. This is the time, this difficult time, that this safety net should perform its basic function.

We are doing our best to support Hong Kong in this epidemic fight. Let's weather the storm and brave the challenges together.

This is the Letter to Hong Kong by Secretary for Labour & Welfare Dr Law Chi-kwong on anti-epidemic measures and the Employment Support Scheme carried on Radio Television Hong Kong Radio 3 on April 19.

The Centre for Health Protection today said recovered COVID-19 patients or those who did not have any symptoms may be discharged from hospital 10 days after the onset of symptoms or a positive test result.

Its Communicable Disease Branch Head Dr Chuang Shuk-kwan told a press briefing that the revised discharge criteria was based on the latest scientific evidence.

“Our Scientific Committee on Emerging & Zoonotic Diseases met yesterday and examined the latest scientific evidence on whether the virus will be viable from a patient.

“And the available evidence showed that this virus is usually not detected after 10 days since the onset of symptoms of patients. Some patients may have persistent positive PCR (polymerase chain reaction) for a long period of time.”

Dr Chuang noted that patients still had to meet the criteria of having two clinical specimens test negative, or testing positive for the SARS-CoV-2 antibody to be discharged.

“We have revised the discharge criteria to include the patient who (must have) been staying in the hospital for at least 10 days after the onset of symptoms. So this is the additional criteria, in addition to the previous criteria of two consecutive negative specimens.

“We added another criteria (which is) in case a patient has stayed in the hospital for a long time, more than 10 days since the onset of symptoms, but he or she has persistent positive PCR despite the Ct (cycle threshold) value being very high, they can check their serology, the antibody. So if the antibody turns positive, usually it is after 10 days, then he or she can be discharged.

“So this is based on the latest scientific evidence.”

S-Palmitoylation is a reversible post-translational lipid modification that dynamically regulates protein functions. Voltage-gated sodium channels are subjected to S-palmitoylation and exhibit altered functions in different S-palmitoylation states. Our aim was to investigate whether and how S-palmitoylation regulates Nav1.6 channel function and to identify S-palmitoylation sites that can potentially be pharmacologically targeted. Acyl-biotin exchange assay showed that Nav1.6 is modified by S-palmitoylation in the mouse brain and in a Nav1.6 stable HEK 293 cell line. Using whole-cell voltage clamp, we discovered that enhancing S-palmitoylation with palmitic acid increases Nav1.6 current, whereas blocking S-palmitoylation with 2-bromopalmitate reduces Nav1.6 current and shifts the steady-state inactivation in the hyperpolarizing direction. Three S-palmitoylation sites (Cys1169, Cys1170, and Cys1978) were identified. These sites differentially modulate distinct Nav1.6 properties. Interestingly, Cys1978 is exclusive to Nav1.6 among all Nav isoforms and is evolutionally conserved in Nav1.6 among most species. Cys1978 S-palmitoylation regulates current amplitude uniquely in Nav1.6. Furthermore, we showed that eliminating S-palmitoylation at specific sites alters Nav1.6-mediated excitability in dorsal root ganglion neurons. Therefore, our study reveals S-palmitoylation as a potential isoform-specific mechanism to modulate Nav activity and neuronal excitability in physiological and diseased conditions.

(University of Cambridge) Parents should not feel pressured to make their young children undertake structured learning or achieve specific tasks, particularly during lockdown. A new study of children under the age of two has found that parents who take a more flexible approach to their child's learning can - for children who were easy babies - minimise behavioural problems during toddlerhood.

(Anglia Ruskin University) A new study has found an association between low average levels of vitamin D and high numbers of COVID-19 cases and mortality rates across 20 European countries.

(George Mason University) The team's work supports evidence-based decision making, informed by models, to rethink and facilitate hospital operations during the pandemic.

(Michigan Medicine - University of Michigan) Now, as hospitals across the country start to return to doing non-emergency operations that keep their beds full and their books balanced, they need to think carefully about what resources each of those procedures will need as the pandemic continues. A new guide could help them prioritize and plan. Created by poring over seven years' worth of data from 17 common operations in dozens of hospitals, it's available for free for any hospital to use.

(Goethe University Frankfurt) According to modern particle physics, matter produced when neutron stars merge is so dense that it could exist in a state of dissolved elementary particles. This state of matter, called quark-gluon plasma, might produce a specific signature in gravitational waves. Physicists at Goethe University Frankfurt and the Frankfurt Institute for Advanced Studies have now calculated this process using supercomputers.
