That’s one reason an oxygen deficit deep in the oceans is a problem – and climate change is making it worse.

Key Points: 
  • That’s one reason an oxygen deficit deep in the oceans is a problem – and climate change is making it worse.
  • This is important because creatures in the ocean are reliant on oxygen to survive in the same way as animals on land are.
  • The tides act to stir up deep water nutrients, which promote the growth of microscopic plants known as phytoplankton.

Beyoncé and Dolly Parton’s versions of Jolene represent two sides of southern femininity

Retrieved on: 
火曜日, 4月 23, 2024

On her new album, Cowboy Carter, Beyoncé puts a new spin on Dolly Parton’s classic song, Jolene.

Key Points: 
  • On her new album, Cowboy Carter, Beyoncé puts a new spin on Dolly Parton’s classic song, Jolene.
  • Some people commenting online were vocal about not liking Beyoncé’s version, often citing its lack of vulnerability when compared to Parton’s version.
  • There are upwards of 80 covers of Jolene, but Beyoncé’s is a departure from the rest.
  • The Houston native’s Jolene is decidedly Black, and therein lies the crux of the different reactions towards the song.
  • It is important to examine the story Dolly Parton tells on Jolene because it, too, is rooted in her racial and gendered identity as much as Beyoncé’s Jolene is.

How is Beyoncé’s story the same but different?

  • Towards the end of the song, Beyoncé and her partner turn a corner and offer hope against the disruption that Jolene represents.
  • Beyoncé’s Jolene is introduced by Dolly Parton herself in a short interlude.
  • Parton makes a clear association between her experience with Jolene and Beyoncé’s experience with “Becky with the good hair” (or “hussy” as Parton says).
  • But the term has evolved to encompass racially ambiguous women with European or Asian features, lighter skin and loose curls or straight hair.
  • Why would we expect the song to be the same when these two women are far from?

China’s new world order: looking for clues from Xi’s recent meetings with foreign leaders

Retrieved on: 
金曜日, 4月 19, 2024

This has also meant that Chinese foreign policy has become more personalised and that Xi’s own diplomatic engagements offer potentially important clues about its direction.

Key Points: 
  • This has also meant that Chinese foreign policy has become more personalised and that Xi’s own diplomatic engagements offer potentially important clues about its direction.
  • The international order is clearly in flux and a key driver of this change, by its own admission, has been China.
  • Read more:
    Xi and Biden spoke on the phone for 105 minutes: what does this say about their relationship?

The European dynamic

  • Engagements with Germany, however, also have a broader European, and especially EU dimension.
  • Germany now has its own moderately hawkish China strategy, aiming to reduce economic reliance on Beijing.
  • But Berlin is still considered softer than many other EU member states and therefore an important ally for Beijing within the EU and in EU-US deliberations on China policy.
  • From a German and European perspective, the Russian conduct in the war against Ukraine remains a key concern.

Scholz and Xi on diplomacy

  • These included sovereignty and territorial integrity, and the importance to explore diplomatic ways to end the war.
  • What is significant is Scholz’s statement that rather than western military support for Ukraine, diplomacy now takes centre-stage.
  • China’s approach to managing, and shaping, the fluidity of the international system relies predominantly on diplomacy, albeit with a significant coercive streak.

Could Albanese’s bet on homegrown green industries be the boost our regions deserve?

In 2022, America launched its mammoth Inflation Reduction Act and the CHIPS and Science Act.

Key Points: 
  • In 2022, America launched its mammoth Inflation Reduction Act and the CHIPS and Science Act.
  • China, of course, moved first, and dominates the market for most clean energy products, from solar panels to wind turbines and batteries.
  • For Australia, efforts to reshore manufacturing and stimulate new industries should focus on supporting and stimulating regions.
  • If they becomes reality, these plans present a rare chance to make our regions into sustainable economic powerhouses.

Boosting the regions

  • The developer could employ locals, and – if efforts to bring back manufacturing pay off – locally made components could be used wherever possible.
  • This is why the proposed Future Made In Australia Act is a very real opportunity to deliver energy justice for our regions and rural communities.
  • Queensland might be a first mover here by legally defining social license and requiring renewable energy developers to engage with communities.

    Made in America: how Biden's climate package is fuelling the global drive to net zero

Could Australian-made really work?

  • There’s a low chance we will go directly head-to-head with green energy giants such as China.
  • For instance, we’re already one of the world’s top per capita users of solar, and our food exports are highly regarded.
  • Australia has world-leading solar photovoltaic expertise, which we could tap into to create custom-designed agrivoltaics solutions, co-designed with farmers.
  • The timing is good – the World Economic Forum earlier this year called for better financing and development of these types of technologies.
  • Like agrivoltaics, these kinds of inventions offer double benefits – cut carbon emissions, boost farm productivity.

We should use our comparative advantages

  • But what is clear is it represents a real chance for our regional and rural communities to lead the energy transition.
  • And we can do it while uplifting the regional and rural communities which will play home to this transition.

Hard work and happy accidents: why do so many of us prefer ‘difficult’ analogue technology?

The appeal of the slow

Saved from demolition

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.

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”.

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

Retrieved on: 
木曜日, 4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.

China has finally removed crushing tariffs on Australian wine. But re-establishing ourselves in the market won’t be easy

Retrieved on: 
水曜日, 4月 10, 2024

China’s Ministry of Commerce has finally ended its tariffs on Australian wine, which had been imposed for more than three years at rates as high as 218.4%.

Key Points: 
  • China’s Ministry of Commerce has finally ended its tariffs on Australian wine, which had been imposed for more than three years at rates as high as 218.4%.
  • In 2019, Australia sold A$1.24 billion worth of wine to China, surpassing France to capture a market share close to 40%.
  • Last year, US imports of Australian wine actually fell by about 20%, the UK held flat, and sales to India remain trivial.

Since we’ve been gone

  • The departure of Australian wine from the Chinese market created a gap that was quickly filled by other suppliers.
  • But the size of China’s imported wine market has also more than halved over this period, falling from A$3.3 billion in 2019 to A$1.5 billion last year.
  • On re-entry, Australian wine producers are set to face stiff competition in a significantly smaller market.
  • Major Australian producers like Treasury Wine Estates have maintained sizeable staff headcounts in China, expecting the Chinese market to return to prominence in their business.

Lessons for Australia – could it happen again?
