馬臨記憶

上周一,中大前校長馬臨逝世,享年93歲。

馬臨校長很有威嚴

我曾經在1986年及1987年分別當過中大學生會副會長和會長,剛巧這也是馬校長任期最後兩年,所以我也有機會與他親身交往過。

我記得,馬臨是一位很有威嚴的校長,且相當「家長」。但其實,當年的大學教授大多數都是如此「家長」,畢竟當時的社會氣氛與今天十分不同。

為何師父教徒弟要教上10年?

我最記得每次到校長室見馬校長,在展開任何話題和討論前,他例必先訓誡我們10多分鐘,說要尊師重道。我還記得,他總是說:「以前師父教徒弟,一教隨時要教上10年,但其實真功夫可能不用兩三年便可教曉,那麼為何要教那麼長呢?其實,頭幾年師父都只不過是觀察徒弟是否孺子可教。所以做學生切記要懂得尊師重道,否則吃虧只會是自己,學不到老師的真正學問。」

這段話他實在向我說過太多次,所以時至今天我仍然清楚記得。

只有交代了這種背景和心態,大家才會明白到,當我們那兩屆學生會提出在改革校政上,要求校方引入教學評核時,校方不少人士為何會認為我們不懂尊師重道。他們想:你們這班學生憑什麼可以去評核老師的教學?他們甚至有人認為,這無疑是對老師「紅衛兵」式的批鬥,因而勃然大怒。

提出教學評核被怪責不尊師重道

我們也不敢直言當時有部分老師實在教得有幾差,完全不備課,上堂天馬行空、東拉西扯,生怕實在太過頂撞校方,不歡而散,唯有耐心多講民主理念。

為了盡量減低校方和老師們的敵意,我們學生會也嘗試做了一些較正面的事情來表達善意,及為教學評核作出平衡,於是我們破天荒搞了第一屆最佳教學獎選舉,表揚教書教得好的老師,由每個學系每名同學一人一票選出他們認為該系教學最佳的老師,之後再出版特刊,由得獎老師分享教學經驗。這樣用心良苦,為的是要避免被人認為學生會只識得「有破壞無建設」,以及讓大家看到,同學表達對老師教學的意見,哪怕是一人一票選舉,其實也不是什麼洪水猛獸。

風物長宜放眼量

我還記得當年政政系(政治與行政學系)的鄭宇碩教授、新聞系的李少南教授、哲學系的關子尹教授等,都在我們舉辦的選舉中得獎。

30年過去了,當日由學生提出、曾經被校方不少人嗤之以鼻的東西,例如教學評核和最佳教學獎等,今已經成為大學體制中不可或缺的環節。如今老師教的每一科,到學期尾都要由學生填寫問卷作教學評核,並會作為老師升職、續約等的參考;大學的學院、書院亦每年會辦最佳教學獎選舉。

所以評價學生所做的事,往往不要只爭朝夕。還是那一句——風物長宜放眼量。

今天,與同事聊天,不時會聽到吐苦水,說教學評核讓大家不敢對學生太過harsh,怕被學生「e死」(即teaching evaluation時給予很低的分數),於是便有grade inflation(老師派grades時「手鬆」)、為學生提供詳盡的lecture notes(副作用是讓學生考試讀notes就夠而不會主動多看書)、不敢訓斥學生的不是,甚至有把學生當作是clients,以「顧客至上」的心態去看待。

但世事往往就是如此,針無兩頭利。如果以過來人而論,我會說,今天大學普遍教學質素,一定比起30年前好得多,不備課、上堂東拉西扯的老師基本上已經絕迹。

高錕和馬臨作風截然不同

說回中大校長。馬臨之後是高錕,兩者的性格與作風截然不同。高錕是一個很隨和的校長,他與我們學生會見面時,甚至流露出有點靦腆,完全沒有馬臨那一份威嚴。這裏且舉兩件事作比較,就可看到兩者間的分別。

話說1980年代初中大發生醫學院事件。有一次教務會討論有關課題,會場外,學生在百萬大道烽火台舉行集會,並要求校方對話。當教務會會議結束後,馬臨匆匆離開,並不肯留低對話,惹來學生不滿,結果擾攘一番,甚至發生包圍校長座駕之後,讓他不得不公開回應幾句。不料他卻說,他已經十分肚餓,要去吃飯了,讓學生瞠目結舌。結果在學生一片鼓譟聲下離開。後來學生於晚上再操上校長官邸外抗議,繼續要求對話,但最後仍然不得要領。

另一件事,是在中英雙方就彭定康政改方案而鬧得不可開交時,高錕接受了北京委任,當了港事顧問,被學生聲討,怪責他被統戰和收編。但他卻仍然願意踏入龍潭虎穴,出席由學生所舉辦設在百萬大道烽火台的千人論壇,交代和討論這件事。但不擅辭令的他,最後當然落得尷尬收場。

只可惜,當時高錕的這份胸襟和苦心,卻未為學生所體諒和欣賞。另一方面,又遭校方很多高層人士埋怨他在一系列包括中大開放日等事件中,實在太過遷就學生,太過軟弱。結果落得兩邊不討好,最後讓他鬱鬱離開中大。

When will Hong Kong tackle the health menace of congested roads?

CommentInsight & Opinion
2017-10-25
Barry Wilson says the government is aware of the ills of roadside pollution and even the ways to reduce it, but seems unable to summon the will and courage needed to implement the solutions

 

There is a new realisation that air quality inside buildings can significantly affect health, productivity and happiness. The same is, of course, true for outside air quality, where one in nine deaths globally results from air pollution and the high costs of remedial health care far outweigh the preventive costs.

Awareness of the health issues from emissions should be of particular concern in Hong Kong, where congested streets are common, not to mention the psychological stress resulting from noise and safety issues.

Emissions include particulates from diesel engines, nitrogen oxides, volatile organic compounds, carbon monoxide and benzene. The 2014 Hong Kong Emission Inventory Report indicates that the road transport sector is the largest local air pollution source: 60 per cent of carbon monoxide emissions come from transport.

It’s not just exhaust fumes that are hurting us; brake dust, tyre fragments and even tiny bits of road can get into the air and these make up a similar proportion of the airborne particulate matter resulting from vehicle use as exhaust emissions. This problem won’t be solved by a switch to plug-in hybrids or electric vehicles. In a study published recently in the journal Environmental Science & Technology, the researchers described how vehicle-emitted metals such as copper, iron and manganese interact with acidic sulphate-rich particles already in the air to produce a toxic aerosol.

We need to start paying far more attention to air pollution caused by tyre, brake and road wear. Brake pad dust may come to be reduced through electric vehicle adoption because such vehicles mostly use regenerative braking, which usually needs no brake pads, but tyre and road dust will remain a problem.

Several countries and regions are in the process of implementing programmes to improve tyre efficiency and safety. Rating and labelling programmes along with compliance standards are important first steps. The installation of tyre pressure monitoring systems should become an effective strategy in reducing wear.

Maintaining a steady travel speed is a key factor in reducing pollutant emissions. Lower speeds require less intense wear on brakes. As well, driver behaviour in minimising unnecessary braking and avoiding excessively rapid acceleration becomes a key environmental issue. As such, traffic management features such as “stop lights and speed bumps” can adversely affect air quality. The use of traffic signal systems to improve air quality requires visionary design and committed institutional coordination that appears beyond most governments at present.

In trying to tackle vehicle emission pollution, there is really only one simple solution, and that is to reduce the number of vehicle journeys, particularly in densely populated areas. The Hong Kong Transport Department recognises this and lists a “reduction in vehicular traffic” as its primary “environmental objective”. It targets rationalising public transport services to reduce vehicular traffic and mitigate air pollution.

All well and good. However, the 10 years between 2003 and 2013 saw the overall number of road vehicles in Hong Kong increase by 30 per cent, from 524,000 to 681,000. The Transport Bureau has a responsibility to effectively manage road use, reduce congestion, promote safety and support environmental improvement measures, but unfortunately, it puts traffic efficiency over pollution as a priority. This must change.

During the above period, the average car journey speed in urban areas in fact dropped by about 11 per cent from 25.6km/h in 2003 to 22.7km/h in 2013, so it is getting nothing right.

Pedestrianisation of city centres gained popularity in Europe about 40 years ago, and is now a feature of most developed city-centre plans. The measures used include shade for paths, adopting attractive materials that dissipate heat, greening, integration with public transport and better pedestrian corridor links.

By contrast, pedestrians in Hong Kong, similar to those in developing countries, are generally poorly served. Pavements are often too narrow, inaccessible and behind barriers, in a poor state of repair or taken over by traders and parked vehicles. The consequence is that pedestrians are often forced to walk on the road. This is not only unsafe but increases proximity to exhaust emissions while contributing to impaired traffic flow, which in turn increases emissions.

The provision of adequate pedestrian facilities improves air quality by keeping traffic away from high-exposure locations and by encouraging walking as the preferred mode for short trips. Evidence shows that the integrated planning of urban land use, urban public transport and traffic management is the best basis for improving air quality in the most dense locations.

It seems the government is well aware of all the issues and potential solutions, and yet has no stomach for the fight. The 2014 report from the Transport Advisory Committee on congestion in Hong Kong highlighted that “traffic congestion will continue to erode the environment, sustainability, quality of life and competitiveness of the city and that immediate action is warranted”. That was more than three years ago, and simply led to the third resurrection of the electronic road pricing (ERP) pilot scheme for discussion, a congestion charging proposal first floated almost 30 years ago.

With limited land available in Hong Kong, the primary vision should be to reduce road capacity in the urban centres and enhance the pedestrian environment, connectivity and urban air quality as a direct means to enhancing public health and well-being. An immediate multifaceted approach which could be easily implemented at limited cost to the public is required. It could include ERP but must also focus on a clear programme of street rationalisation and pedestrianisation; the removal of on-street parking; a reduction of parking meters, along with significant and deterrent increases in meter charges; an increased level of traffic penalties; and, increased resources for enforcement.

Such measures require little capital cost, can be immediately and flexibly applied, and may have a significant impact on urban air quality and public health.

The provision of parking generates vehicle journeys. On-street parking is hostile to pedestrians and is provided at the expense of other, more productive investments in space. Where urban density is high, such as in Central District, parking is extremely capital-intensive, making its cost substantial. Most of all, the provision of parking tacitly subsidises car ownership since the vehicles are parked most of the time and ownership is easier if a car can be cheaply and reliably stored when it is not being driven. Removal of on-street parking and idling should be a simple and low-cost first step to reduce congestion.

The fight against public cigarette smoking was a long, drawn-out battle against common sense. Today, there has been an incredible shift in the social norm towards smoke-free environments; indoor workplaces and most public places, including restaurants, are now healthy places. Today, smoking is barely raised as an issue.

The battleground has now moved from indoors to out and needs similar decisive action from the government. As the youth of today like to say, “Just do it already”.

Cashless societies seem convenient, but Hong Kong should think it through first

CommentInsight & Opinion
2017-10-24

Peter Kammerer says we need a debate over going cashless, which benefits shoppers, stores and governments, but also has some worrisome implications for privacy, individual financial security and also government debt

Fintech Week in Hong Kong may not seem the right occasion to raise questions about rushing headlong into a cashless future. But there are as many downsides for all the benefits of ditching banknotes and coins. They involve privacy, choice, security and, for financially troubled governments, survival. As much as we should embrace a hi-tech way of life, there’s also a need to debate what’s best.

Not being able to see makes me a natural convert to electronic payments. Give me an app or a card over a handful of notes of uncertain denomination any day. The Octopus card was a blessing when introduced in 1997 and the day of the shop that Amazon envisages, with no checkouts and apps linked to bank accounts, and where sensors deal with transactions, can’t come soon enough for some of us.

Tech giants like Alibaba and Apple see their apps driving such a future and a visit to the mainland or Sweden, where cash accounts for 2 per cent of transactions, shows just how willing some are to embrace the idea. Try to use cash in some Shenzhen restaurants and you’ll get a worried frown; some no longer accept it. It’s all about convenience and there is a concerted push for Hong Kong to follow, in order to – as Jack Ma, the founder of Alibaba, said recently – be “more fashionable, modern and efficient”. (Alibaba owns The South China Morning Post). Hong Kong’s government has embarked on a course of promoting innovation, science and technology.

Credit card companies, and now those involved in electronic payment systems, portray cash as backward and inefficient. It’s difficult to argue against industries that aim to make life easier and create jobs. But as the cashless supermarkets Amazon is trying out in the US show, it’s as much about job creation as making jobs redundant.

Governments may see such losses as inevitable or negligible when compared to the advantages. Going cashless eradicates money-laundering. Their most effective tools to crack down at present are resource-heavy monitoring of currency and bank accounts or scrapping the high-denomination banknotes criminals favour. They can also track transactions by having access to records and more easily shut down money supplies, as in Uganda in February last year to keep funds out of the hands of the opposition during elections.

It’s why the Swiss have been so worried about the introduction of an equivalent of the Octopus card for trains; they fear authorities will spy on their travel patterns. Many shops in Switzerland also prefer cash to credit cards and there have even been pushes by lawmakers to make the use of banknotes and coins permanent, the thinking being, as Swiss people’s party member Manuel Brandenberg put it to Bloomberg last year, “cash is property and cash is freedom. It empowers the individual because it’s tangible wealth.”

There’s another matter that the wealthy Swiss government doesn’t have to worry about, but others may fear; a cashless society will prevent a government from printing banknotes to get out of debt or induce inflation. Robust security systems are also needed to lock hackers out.

Such discussions aren’t taking place on the mainland in the scramble to be modern. Nor have we heard much in Hong Kong, although the idea that cash is king also has firm adherents here, as in Japan, where credit card use is low, too.

That reticence is still seen at bank counters, among taxi drivers who prefer tips in cash and in the surprising number of shops and restaurants that demand cash only. Such restraint offers hope for those worried about the drive to go cashless, and space for a much-needed debate of the issues.
