(American Association for the Advancement of Science) A one-hour exercise designed to increase feelings of social belonging administered during the first year of college appears to significantly improve the lives and careers of black students up to 11 years later, psychologists report.

(Geological Society of America) The annual meeting of The Geological Society of America's North-Central Section, originally scheduled to take place in Duluth, Minnesota, will be held virtually on May 18-19, 2020, with technical sessions in the morning and student programming in the afternoon. The online meeting is open and available to everyone for free. No registration is required.

(Florida Atlantic University) Despite PPE use, reports show that many health care workers contracted COVID-19. A novel training technique reinforces the importance of using proper procedures to put on and take off PPE when caring for patients during the pandemic. Researchers vividly demonstrate how aerosol-generating procedures can lead to exposure of the contagion with improper PPE use. The most common error made by the health care workers was contaminating the face or forearms during PPE removal.

A pet dog repeatedly tested weak positive for the COVID-19 virus, indicating a low-level of infection with the virus, the Agriculture, Fisheries & Conservation Department said today.

The department first collected test samples from the dog on February 26. It detected low levels of COVID-19 virus from its nasal and oral cavity samples on February 27.

The dog also tested weak positive for the virus when the department repeated the test on February 28 and March 2.

Experts from Hong Kong University’s School of Public Health, City University’s College of Veterinary Medicine & Life Sciences and the World Organisation for Animal Health have been consulted, and unanimously agreed that these results suggest that the dog has a low-level of infection and it is likely to be a case of human-to-animal transmission, the department noted.

The dog has not shown any signs of disease related to COVID-19. It is currently under quarantine at the animal keeping facility at the Hong Kong Port of Hong Kong-Zhuhai-Macao Bridge. The department will closely monitor the dog and repeat the test later.

To ensure public and animal health, the department strongly advises that mammalian pets from households with COVID-19 infected people, or close contacts of infected individuals, should be put under quarantine in the department’s facilities.

The department emphasised that there is currently no evidence that pets can be a source of infection of COVID-19 and under no circumstances should people abandon their pets.

People living in units 13 and 14 of the top six floors of Heng Tai House in Fu Heng Estate, Tai Po need to be quarantined as a precaution.

Hong Kong University Chair of Infectious Disease Prof Yuen Kwok-yung made the statement at a media briefing today after an expert team conducted initial epidemiological investigations in the building to find the cause of a new COVID-19 infection.

The new case announced this afternoon involves a 59-year-old man who lives on the 34th floor of the building.

Prof Yuen said: “There is a possibility that when the patients on the 32nd floor are defecating - we know now that the fecal material actually contains the virus - while they’re defecating the fecal material goes into the sewer system.

“There is a vent of air that comes through the venting pipe, which goes to the top floor and maybe aerosolised in the air and then the droplets try to settle but, while at the same time, when there’s a light wind blowing, in which the air current going over the rooftop carries the particles back into the top floors.

“And of course, the 34th floor is the top floor. That is the most dangerous, followed by the 33rd and 32nd floors.”

Prof Yuen added he is uncertain if the venting pipe will continue to produce more infected aerosolised particles.

“So it is just a precautionary measure that we must remove the residents from the top six floors in units 13 and 14 for a period of time.”

As for LCSD facilities, its free outdoor leisure facilities will be closed from 6pm on March 28.

Other venues and facilities with services already suspended will continue to be closed until further notice.

All booking applications for the department's recreation and sports facilities, wedding venues, amphitheatres and non-fee charging leisure venues for non-designated use are also suspended.

Meanwhile, the Housing Authority will close its outdoor sports and recreational facilities from 6pm tomorrow until further notice.

The Government today said the first batch of subsidies amounting to $5.6 million under two relief measures for recyclers has been disbursed, while $5.6 million in subsidies had been approved under a management sector support scheme.

The two Recycling Fund measures aim to help the recycling industry cope with the current economic situation and recent operational difficulties arising from the COVID-19 epidemic.

The Advisory Committee on Recycling Fund announced in mid-March to reserve $100 million to launch the One-off Recycling Industry Anti-epidemic Scheme.

The scheme provides timely financial support to help with recyclers’ operational costs for six months. The funding limit for each recycler is $20,000 per month from January 1 to June 30, or $120,000 in total maximum subsidy.

The committee has also allocated additional funds to extend the earlier-launched One-off Rental Support Scheme for another six months, providing a total funding of $200 million to fight the virus and help the recycling industry ride out the difficult times.

The rental support scheme, which benefits street-corner recycling shops and recycling sites, originally ran from October to March. It has been extended for six months until September this year, totalling 12 months.

The monthly rental subsidy for each recycler is capped at $25,000, setting the maximum total rental subsidy at $300,000.

Separately, the Anti-epidemic Support Scheme for Property Management Sector has approved 205 applications involving around $5.6 million in subsidies to benefit more than 1,500 building blocks.

The relevant property management companies and owners’ organisations will receive notifications for subsidy disbursement shortly.

The list of properties for which applications have been approved is available online.

Briefing sessions were held earlier to introduce the scheme to the property management sector and owners’ organisations.

The Agriculture, Fisheries & Conservation Department (AFCD) announced today that country park barbecue sites and campsites will remain closed until April 23.

The 163 barbecue sites and 41 campsites managed by AFCD have been closed since March 28. Given the latest development of COVID-19, the department has decided to extend the closure.

During the closure of these facilities, no barbecuing or camping activities are allowed in country parks.

AFCD staff will step up patrols of these sites and violation of relevant regulations will be subject to prosecution.

Call 1823 for enquiries or visit the Enjoy Hiking website for updates.

The department also reminded people visiting country parks to maintain personal and environmental hygiene and maintain social distancing.

The Agriculture, Fisheries & Conservation Department (AFCD) today announced that its barbecue sites and campsites in country parks will be closed until May 7.

It made the decision in light of the latest development of the COVID-19 epidemic and to reduce social contact.

All of these sites have been closed since 6pm on March 28.

During the closure of these facilities, no one should carry out barbecuing or camping activities in country parks.

AFCD staff will step up patrols of the sites and violation of relevant regulations may be subject to prosecution.

In the past two weeks, AFCD took enforcement action against 34 people who carried out barbecuing or camping activities in country parks.

The department will continue to closely monitor the situation and review the arrangement as appropriate.

For the latest updates on facilities in country parks, visit the Enjoy Hiking website.

The Government today announced that the Environment Bureau has disbursed about $6.5 million in subsidies to 809 private municipal solid waste collectors by cheque.

Under the Government's latest round of anti-epidemic measures, the bureau launched the Subsidy Scheme for the Refuse Transfer Station Account Holders for Transporting Municipal Solid Waste to provide a one-off relief subsidy of $8,000 to each eligible private municipal solid waste collector.

To provide financial support to the industry as soon as possible, the Environmental Protection Department, following funding approval by the Legislative Council Finance Committee, expedited the subsidy disbursement arrangement by waiving the application procedures.

The cheques have been issued and posted to all eligible private collectors.

Eligible collectors are refuse transfer station account holders who transported municipal solid waste to refuse transfer stations or landfills in the first quarter of the year.

The subsidy will assist them in increasing resources to enhance workers' personal protective equipment and strengthen the disinfection of refuse transport vehicles to curb the risk of virus transmission and maintain environmental hygiene.

Abstract, references and article information

A 53-year-old building on Fa Yuen Street near Prince Edward, like most of the buildings in Yau Tsim Mong District, was in poor condition two years ago. Walls, both inside and out, were worn down, staircases were broken, and with electrical installation panels exposed on the outside. 

But with the help of various subsidy schemes launched by the Government and Urban Renewal Authority, older buildings are being given a new lease of life. The schemes include Operation Building Bright 2.0 (OBB 2.0), the Fire Safety Improvement Works Subsidy Scheme (FSWS) and the Lift Modernisation Subsidy Scheme (LIMSS).
 

Helping hand

Octogenarian owner-occupiers Leung Ting-lam and Chu Lai-chun have lived in this building on Fa Yuen Street for more than two decades. They welcome the improvements, which include a new metal gate and lift.

“Modernising the lift was done so quickly. It only took a few months and that was the most satisfying part,” said Mr Leung. Ms Chu agreed that the lift no longer breaks down so regularly.

It cost $800,000 just to modernise the lift. Add to that the other repair and maintenance works, and the total cost exceeded $3 million. Those who own a flat had to shoulder tens of thousands of dollars in the 10-storey building containing 19 units.

For seniors on a fixed income, it is not easy to cover the full cost of repair works. With the government subsidies, they no longer have to worry about the financial burden of upgrading their buildings on their own.

Popular services

The lift modernisation work under the LIMSS is assisted by the Electrical & Mechanical Services Department. The department’s Assistant Director Raymond Poon said the subsidy can cover up to 60% of the total cost of the works - plus a consultation fee - with a cap of $500,000 per lift for eligible buildings.

For elderly owner-occupiers, they can receive the full cost of relevant works capped at $50,000 per domestic unit.

Up until August 1, the department received around 1,171 applications for the scheme involving nearly 5,000 lifts in the first round of applications. This far exceeded the quota of 1,400 lifts set for the round, a response Mr Poon described as overwhelming.

Apart from the LIMSS, owner-occupiers can also apply for OBB 2.0 and other schemes to cover maintenance costs.

In one 58-year-old Hung Hom building, residents had to spend more than $800,000 to paint the common areas, replace above-ground drainage pipework and other structural upgrades.

The building’s owners’ corporation has applied for several funding schemes to get some financial relief, including OBB 2.0. Under this scheme, elderly recipients can receive the full cost of the work, subject to a cap of $50,000. Other owner-occupiers can receive 80%, capped at $40,000.

As of August, the owners or owners’ corporations of 479 Category One buildings were prepared to carry out the prescribed inspection and repair works for the common areas of their buildings under OBB 2.0. They can do so on a voluntary basis to comply with the Mandatory Building Inspection Scheme (MBIS) statutory notices.

These buildings are in 13 districts. Among them, Yau Tsim Mong has the largest number of applications, followed by Kowloon City and Sham Shui Po.

More help ahead

In the future, another $3 billion will be injected into OBB 2.0. This means a total of $6 billion will be used to benefit 5,000 buildings.

Development Bureau Principal Assistant Secretary Jasmine Choi said they have received feedback from the community which hopes the operation will eventually allow younger buildings to join the rehabilitation schemes.

Upon review, buildings between 40 and 49 years old with an outstanding MBIS statutory notice not yet complied with will be accepted in the next round of applications.

Apart from these younger structures, OBB 2.0 will also accept buildings aged 50 and older, even if they do not have an outstanding notice.

Stretching from Sai Kung on the east coast to Tuen Mun in the west, the whopping 100 km-long MacLehose Trail is the longest and first long-distance hiking trail in Hong Kong.

The trail is divided into 10 sections and traverses eight country parks which embrace magnificent natural scenery, interesting historical relics and a wide range of wild fauna and flora, winding past the coastline, rugged mountains, valleys and reservoirs to provide a diverse outdoor experience for hikers.

It was even named as one of the world's 20 dream trails by National Geographic.

A lot of hard work went into building the trail, with Agriculture, Fisheries & Conservation Department workers out in the elements without much shelter, often carrying heavy equipment uphill and downhill over varied terrain.

Building bonds

Wan Keung and Lai Hing joined the department around 40 years ago. They both took part in the MacLehose Trail project which was started in 1979 to promote hiking activities in Hong Kong.

The project was named after the then-Governor Sir Murray MacLehose - who was himself a keen walker - for his significant efforts to conserve Hong Kong’s countryside.

“I have contributed a lot to the trail. I am happy as it is packed with people now,” said Mr Wan.

While Mr Lai added: “We are going to retire, but the trail will be here for a long time.”

Despite working on the same project, the pair - now in their 60s - only met for the first time recently because they were assigned to different work stations back then. However, they became firm friends instantly.

From setting up the many signposts along the way, to hand-building the heavy stone steps, the two men eagerly shared all the skills and techniques they learnt on the project.

Listening to their conversations now it is hard to imagine that when they first started work, both had little practical knowledge about constructing a trail. They acquired welding, plastering and woodwork skills through hands-on experience and with the support of their seniors. But that was not the biggest challenge they encountered.

“Building the trail was really difficult, as there were so many sections. We were either drowned in sweat or drenched by rain while working,” Mr Lai explained.

One poignant memory for Mr Wan was of working during wildfires that raged through the countryside.

“There was only one thing for it: we stayed until the fire was extinguished. That was really hard.”

Lasting legacy

After nine months’ hard work the MacLehose Trail was finally opened on October 26, 1979.

These days Mr Wan and Mr Lai enjoy the trail for leisure instead of work.

Both said receiving compliments from family and friends or witnessing the sheer enjoyment of hikers on the trail made their hard work worthwhile.

They now hope to pass on their skills to the younger workers, so that a new generation of Hong Kong people can take care of the trail and ensure it lasts for decades to come.

The Airport Authority expanded the scope of its food waste recycling programme in 2011 to cover Hong Kong International Airport business partners, including restaurants and lounges operating in terminal buildings, as well as airline catering companies, hotels and cargo terminals.

In 2017-18, over 2,000 tonnes of food waste from 17 airport business partners were collected for recycling.

Rainie Ho, the supervisor of one participating restaurant, said staff make every effort to collect food waste on a constant basis.

“We have three bins of recycled food waste, including eggs, toast, bread, chicken, meat, pork bones, tea and coffee every day.”

Ms Ho gave kudos to the Airport Authority for making the process simple.

“The Airport Authority provides us with garbage bags every month. We explain to our staff that the red bags are for food waste, while the black ones are for general rubbish. This makes it easier for them to remember and handle.”

Airport Authority Assistant General Manager (Sustainability) Mike Kilburn is the facilitator of the food waste recycling programme. He hoped to encourage more business partners to join by making the scheme as trouble-free as possible.

“This is an example of an easy, useful and free programme because the contractor comes to collect from each company and the contractor provides a clean rubbish bin for the food waste, they take the food waste away, they wash the bin and then they bring it back clean.

“And it is useful because the food waste is not just sent to the landfill, but it is turned into fish meal so it goes back into the food chain because the fish meal is fed to the fish and the people can eat the fish, so it is a very complete system.”

Surplus food collection

In addition to food waste recycling, the authority promotes the Food Rescue Programme in co-operation with a local non-governmental organisation called Food Angel.

In 2013, the authority helped Food Angel to purchase a refrigerated truck and covered the cost of collecting surplus food from business partners on the airport island.

By 2014, a central storage room was set up in the terminal building to collect even more surplus food from catering outlets.

By proving it can reduce its environmental impact by working closely with the entire airport community, the authority was recognised at the 2018 Hong Kong Awards for Environmental Excellence where it won the Gold Award for the Public & Community Services Sector.

Future prep

In 2018, the authority launched a voluntary municipal solid waste charging pilot scheme to achieve waste reduction.

It has assisted more than 200 tenants with measuring their waste generation and calculating what it would cost to dump it in the future.

Another participating restaurant manager Alfred Lau explained that the pilot scheme helps restaurants gear up for the polluter-pays principle.

“A mock monthly invoice was issued to us, showing the quantity of waste disposed and the estimated disposal charge. Now we understand that by reducing our waste, we will pay less in the end.”

Mr Lau believes the pilot scheme encourages eateries to alter their disposal behaviour by recycling as much food waste as possible.

“Our disposed waste amount fell sharply once we learnt useful ways to recycle. Our restaurant is located in the restricted area of the airport where drinks are not allowed to be brought inside. So many passengers buy bottled drinks and create a large amount of plastic waste. Just by recycling plastic bottles, our waste decreased significantly.”

The authority said it is proud to be the driving force behind waste reduction.

“We make it easy for them because we do all the organisation, we make it useful because they can help them to prepare, and it is free for them to join the programme. This is very important for us because as the Airport Authority, our job is to create a concept that other people can follow and if you address those three criteria, you make it very hard for them to say no to you. We take away their reasons to say no, so it is easy for them to join our scheme,” said Mr Kilburn.

The Hong Kong Awards for Environmental Excellence is led by the Environmental Campaign Committee alongside the Environmental Protection Department and in conjunction with nine organisations. The objective is to reduce Hong Kong’s environmental impact by promoting environmental management.

The Airport Authority’s current target is to reduce, recycle and recover 50% of all its waste by 2021.
