The source of contamination is believed to be timber waste from construction and demolition sites that was turned into mulch.

Key Points: 
  • The source of contamination is believed to be timber waste from construction and demolition sites that was turned into mulch.
  • So far, 60 locations in Sydney and 12 in Melbourne have been identified as contaminated with asbestos to various degrees.
  • The severity, spread and impact of the issue convince us to call it the largest scandal in the history of Australia’s circular economy.
  • A circular economy recycles and reuses materials or products with the goal of being more sustainable.

Scandal is damaging for the circular economy

  • Unfortunately, this contaminated mulch raises concerns about the reckless implementation of circular economy principles in Australia.
  • More broadly, this scandal could undermine efforts to advance the circular economy in Australia.
  • It’s a reminder that the circular economy concept is based on a system-thinking approach, where all elements must work in harmony.

Regulations don’t go far enough

  • However, it isn’t mandatory for suppliers to test for contaminants in mulch.
  • The fact is existing policies and regulations, such as the NSW Environment Protection Authority’s Mulch Order 2016, failed to prevent mulch contamination.

Why isn’t certification standard practice?

  • In 2022 and 2023, working with researchers from Griffith and Curtin universities and our industry partners, we explored the use of recycled product certification schemes.
  • We specifically asked for their views on certification schemes for these materials.
  • He added:
    The cost of certification is a fraction of whatever their marketing budget might be in any single month, let alone a year.
  • If they can see that their certification becomes part of their marketing budget, then the cost of certification is a single-digit percentage of most marketing budgets.
  • If they can see that their certification becomes part of their marketing budget, then the cost of certification is a single-digit percentage of most marketing budgets.

What more can be done?

  • Our research identified seven major drivers for adopting certification schemes when procuring recycled materials, as shown below.

Up two flights of stairs, the music machinery on offer includes brands such as Moog and Buchla, as well as modern euro-racks.

Key Points: 
  • Up two flights of stairs, the music machinery on offer includes brands such as Moog and Buchla, as well as modern euro-racks.
  • (From Michael’s fieldnotes)
    I finally locate the legendary Schneiders Buero, a shop selling analogue synthesizers in Berlin’s Kotti neighbourhood.
  • Up two flights of stairs, the music machinery on offer includes brands such as Moog and Buchla, as well as modern euro-racks.
  • (From Michael’s fieldnotes) As academics who rarely go a day without playing or making music, we have spent the past decade examining the extraordinary revival of analogue technology.
  • This means there are now more analogue options available than at any time since the 1970s, the heyday of the modular format.

The appeal of the slow

  • So we dived in.
  • Eventually, these forays became our formal research project, which has included visiting record fairs and conventions around the world, going on photowalks and attending listening evenings, and meeting an array of diehard analogue communities both on and off line.
  • The team is working with academics from different backgrounds who have been engaged in projects aimed at tackling societal and scientific challenges.
  • And we expect interest in such experiences to rise exponentially in coming years.
  • Recognising our existential need to occasionally slow down can be the basis for winning consumer strategies.

Saved from demolition

  • Rather than nostalgia, they are turning to film because of its aesthetic values and a greater sense of creative control over their photos.
  • In response, venerable brands including Kodak, Polaroid and Leica have re-emerged – in some cases, almost from the dead.
  • We literally saved it from demolition at the very last second in 2008.

Work, effort, meaning

  • When it was conceded that digital probably was better for wildlife photography, James cut in:
    That’s to miss the point!
  • The sound might be better but you miss seeing the work that went into the performance, the effort of the players and their crew.
  • Work, effort, meaning – these ideas are all interconnected for users and consumers of analogue technology.
  • However, when asked to compare the two, they talk about the greater weight and meaning they give to their analogue experiences.
  • I think it is the quality of the human voice; it does feel more like someone’s speaking to me.
  • And part of what makes this possible is the process of analogue recording, in which all the sounds being made, including the unscripted noise of the recording process itself, are captured in the final track.
  • To facilitate this sound, some musicians have even started setting up their own pressing plants, such as Jack White’s Third Man Pressing in Detroit.

The joy of happy accidents

  • Half of what you do trying to make music is like a happy accident that ends up sounding better than what you intended.
  • When we started, we didn’t have that technology, so we made mistakes and some of them were happy accidents, resulting in iconic tracks.
  • When we started, we didn’t have that technology, so we made mistakes and some of them were happy accidents, resulting in iconic tracks.
  • It’s these happy accidents that we love.
  • It’s these happy accidents that we love.
  • For example, the opening bass part of Cannonball, the 1993 song by US Indie band the Breeders, accidentally starts in a different key.
  • Bass player Josephine Wiggs began playing the riff one step down, then fixed it when the drums came in.

Digital technology is de-skilling us

  • Over the decade or so of our research, explanations for the analogue revival have shifted from nostalgia, to the desire for something physical in a digital age, to the sense that analogue technology is creatively preferable.
  • Is digital technology de-skilling consumers, leading to a sense of alienation?
  • Using analogue technology is another way consumers can feed this desire to re-skill.
  • Rob told us how his love of music had turned sour with the “sheer ease” of digital, starting with CDs and the MP3 player – and how vinyl had reinvigorated him.
  • For him, the problem came when listening on digital devices without the “sides” of vinyl albums, and then on music streaming platforms whose digital algorithms preference popular tracks.

‘This song sucks’

  • These are the people who want to stretch and break the rules and trigger the happy accidents that create something altogether new.
  • For example, photographers who seek more creative expressions by pre-soaking or “souping” their camera film in lemon juice, coffee, beer, or even burning it.
  • And among this group, connecting digital and analogue technology is also common – combining two completely different systems to generate even more possibilities.
  • Film director Denis Villeneuve’s first instalment of Dune (2021) was initially shot on digital, then transferred to film, before being re-digitised.
  • By combining the two, Villeneuve got a film that, in his words, has a “more timeless, painterly feel”.

Columbia president holds her own under congressional grilling over campus antisemitism that felled the leaders of Harvard and Penn

Retrieved on: 
星期四, 四月 18, 2024

Two of them resigned shortly thereafter.

Key Points: 
  • Two of them resigned shortly thereafter.
  • Here, Lynn Greenky, a scholar of communication and rhetoric, gives her take on how Shafik handled being in the same hot seat as her colleagues.

How did today’s hearing differ from the one on Dec. 5?

  • Of course, they had the benefit of being able to first see what happens when you don’t.
  • Shipman in particular made it clear that Columbia is suffering a “moral crisis” on its campus.
  • They even thanked the committee for the investigation and asked for the committee’s help to address antisemitism on campus.

What did committee members say about faculty?

  • Several members of the Congressional committee singled out Massad, who on Oct. 8, 2023, described the Hamas attack on Israel as “awesome” and “innovative” in an online article, for particular scorn.
  • The committee’s chairperson, Virginia Foxx, a Republican from West Virginia, warned that radical faculty remain a huge problem at Columbia.
  • If not, she says, Columbia will be brought before the committee again.

Was there any conflict over what is hate speech?

  • Shafik seemed reluctant to label students or faculty as engaging in hate and harassment.
  • She tried very hard, sometimes unsuccessfully, to assert the need to balance constitutionally protected speech with the educational mission of the university.
  • Still, Shafik frequently testified that the policies and structures in place at Columbia prior to the Oct. 7 attack were inadequate.

What action did Shafik and her colleagues say they would take?

  • They said they are working on revising policies and practices that will promote vigorous debate while protecting student safety.
  • As a result of some of the preliminary recommendations of Columbia’s Task Force on Antisemitism, the university has updated the reporting and response process regarding harassment and discrimination.

How will all this affect free speech on campus?

  • Certainly, a college or university has a compelling interest in protecting its students, faculty and staff’s freedom, safety and integrity.
  • Often, when colleges and universities undertake the task, I believe it is the freedom to speak one’s mind that suffers.

South Africa’s electricity crisis: a series of failures over 30 years have left a dim legacy

Retrieved on: 
星期四, 四月 18, 2024

Back then only 36% of all South Africans had electricity in their homes.

Key Points: 
  • Back then only 36% of all South Africans had electricity in their homes.
  • The development programme promised to double that number by electrifying an additional 2.5 million homes by 2000.
  • This seemed achievable – during the 1980s, the state-owned power utility Eskom’s build programme was so aggressive it had surplus electricity.
  • By 1994, South Africa’s coal industry was generating high quality coal which was exported mainly to Europe.

What went wrong

  • Eskom tried to convince the government to allow it to build more power stations.
  • But under the macroeconomic policy, the government decided that new power stations must be built by Black empowered businesses.
  • For that to work, the prices of electricity needed to increase to make it financially viable for the businesses.
  • The White Paper was accurate in predicting when the country would run out of power.
  • If the Eskom CEOs had signed the power purchase agreements, it would have brought online 5GW of renewables.

The current dilemma

  • This provided for a very large increase in the number of renewables and the closure of several coal-fired power stations.
  • But Mantashe later delayed the procurement of renewables, deepening the crisis at Eskom.
  • Dividing the utility up was approved in 2019 but the National Transmission Company was only set up in 2024.
  • Ramaphosa appointed an electricity minister, Kgosientsho Ramokgopa, and released the Energy Action Plan to end power cuts.

Solutions

  • It dramatically increases the emphasis on gas – it is a gas infrastructure plan and South Africa doesn’t have much gas.
  • The country will have to import gas and pay in US dollars, thus increasing its dependence on the dollar.
  • Instead, South Africa needs to transition to renewable energy plus backup, which is batteries and a substantial gas reserve.

The Trial of Vladimir Putin: Geoffrey Robertson rehearses the scenarios

In The Trial of Vladimir Putin, barrister Geoffrey Robertson answers that question by dramatising what might happen within the walls of a future courtroom.

Key Points: 
  • In The Trial of Vladimir Putin, barrister Geoffrey Robertson answers that question by dramatising what might happen within the walls of a future courtroom.
  • The question of whether Putin is guilty of aggression is fairly straightforward.
  • Evidence would be needed that he is responsible in his role as a commander for actions carried out by subordinates.
  • Instead, a special aggression tribunal would have to be established in the tradition of the trials of Nazis at Nuremberg.
  • It is not pure fiction; it is speculation informed by Robertson’s experience.
  • The details he imagines will bring these potential future trials to life for readers who are less familiar than he is with the inside of a courtroom.
  • Does Robertson really need to tell us three times that any judgements should be uploaded to the internet?

Rhetorical devices

  • Whether Putin should be tried even if absent is a hard question because there are arguments on both sides.
  • Instead, he uses rhetorical tools such as hyperbole: if “international law is to have any meaning”, he writes, then a trial in the defendant’s absence “must be acceptable”.
  • Robertson criticises this with the remark that it “entitles a man who has given orders to kill thousands to stand back and laugh”.
  • It is that he gives the impression that the complexities do not exist.
  • Dismissive language is a more general feature of his writing style.
  • The implication is that Robertson is atypical among lawyers, someone who will sweep aside conventions and assumptions.

The United Nations

  • One of the bolder elements in the book is what Robertson says about the United Nations.
  • One of them is that the Security Council could authorise, say, the United States to take military action against another nuclear-armed major power: is that outcome “obviously right”?
  • The same logic might be used to justify expelling the United States, Britain and Australia, which were accused of unlawfully invading Iraq in 2003.
  • Robertson compares the UN unfavourably with its predecessor, the League of Nations, which “expelled the USSR for attacking Finland”.

  • Nickel Asia Corporation, a nickel producer from the Philippines, reported a decrease of 53% YoY in net profits in fiscal year 2023.
  • The general downturn of the nickel industry in 2023 reflects the fact that the global oversupply of nickel has not changed in the past two years.
  • On the other, the nickel supply-demand situation has seen predictions for marginal improvement, and this will surely boost nickel price.
