It’s a question still hanging over Brisbane’s plans for the 2032 Olympics.

Key Points: 
  • It’s a question still hanging over Brisbane’s plans for the 2032 Olympics.
  • Often economic studies are carried out before the events to build the case for hosting them.

The Sydney Olympics’ $3.7 billion cost

    • Our study found the 2000 Olympics reduced Australia’s real private and public consumption by about $3.7 billion (adjusted to 2023 dollars) over the nine years in which the Olympics impacted the economy.
    • It is often claimed that hosting the Olympics brings intangible benefits to the host nation – things such as national pride and social cohesion.

How to calculate the value of a mega event

    • It’s important to use a model equipped for the task, and to properly simulate the effect of the event.
    • In the past, major event studies – such as KPMG’s pre-Sydney Olympics study – used input-output models.
    • Modern CGE models track deviations from what would have otherwise happened, as the effects of an event work their way through the economy.
    • Studies undertaken before the event often include predicted legacies, such as a large boost to tourism following the event.

Feelings aside, the Sydney Games had a net cost

    • The net direct cost of the Sydney Olympics (Olympic costs not funded by Olympics revenue), when updated to 2023 prices, was $4.5 billion.
    • A frequent claim by proponents of big events is that the demand stimulus from the event will far offset its net direct cost.
    • But our real consumption result indicates the demand stimulus offset only about a fifth of the net direct cost.

Feelings and other intangible benefits

    • That is a sizeable figure to pay for the intangible benefits not already counted in the prices of tickets, broadcasting rights and other organising committee sales.
    • However, those intangible benefits – including national and sporting pride, a feelgood atmosphere and inspiring children – might also be sizeable.
    • There are no estimates for the value of intangible benefits from the Sydney Olympics.
    • The UK study showed households outside London also perceived intangible benefits, though only half as much per household as their London counterparts.

Lessons for future mega events

    • In all of the work that’s been done to date on the economics of hosting mega events, a few lessons stand out.
    • Events with wide appeal can generate enough revenue to cover their operating costs – and this was the case for the Sydney Olympics.
    • The most important lesson is that bidders for such events ought to conduct a rigorous analysis of the event’s expected net value before submitting their bids.
    • Some mega events might pay their way, when intangibles such as the feelings they engender are taken into account.

eNaira: Nigeria's digital currency has had a slow start - what's holding it back

Retrieved on: 
Wednesday, July 19, 2023

Nigeria was the first country in Africa to roll out a central bank digital currency.

Key Points: 
  • Nigeria was the first country in Africa to roll out a central bank digital currency.
  • Central bank digital currencies are well placed to serve as the anchor for all forms of digital assets and digital currencies.
  • The Central Bank of the Bahamas and the Eastern Caribbean Central Bank have issued their own central bank digital currency.
  • Adoption has been slow and accessing central bank digital currency has been a challenge.
  • It is piloting its central bank digital currency, called e-CNY, in 26 cities but still experiencing poor adoption.

Barriers to adoption

    • It is believed that the Central Bank of Nigeria wants to develop its own software for the digital currency.
    • It is, however, reported that banks and financial institution staff do not appear well trained to get users on board.
    • So the system is not fully ready for adoption.
    • Data privacy: Under the current design, the central bank will be able to see all transactions of users of the eNaira.

Workable solutions

    • Users could also get incentives to use the digital currency, in the form of discounts when paying taxes and for other public services.
    • If these challenges can be surmounted and policy approaches to adoption implemented, adoption of the eNaira is likely to pick up.

Hip-hop and health – why so many rap artists die young

Retrieved on: 
Wednesday, July 19, 2023

Rappers and rap fans can’t help but take notice that their peers and favorite rappers are dying young.

Key Points: 
  • Rappers and rap fans can’t help but take notice that their peers and favorite rappers are dying young.
  • Trugoy the Dove of De La Soul, 53, passed away in February 2023 after a battle with congestive heart failure.
  • Rapper Jim Jones has claimed that rap is the most dangerous profession due to rappers being violently killed so frequently.

The (un)exceptional spectacle of American gun violence

    • News media are quick to report on violence in hip-hop to support their view that the music and the people who make it are exceptionally violent.
    • Violence, death and conflict attract attention.
    • Though they were all taken by the very American plague of gun violence, news and historical accounts often amplify the spectacle of violent Black death, even when they claim to honor those who are killed.
    • It is also the topic addressed in the song “ANKH” from my forthcoming mixtap/e/ssay, “V: ILLICIT”: “He died by the gun but they blamed the music.
    • Another heartbreaking consequence is that some rappers only gain wide popularity and realize financial success after they’ve died.

Deadly diseases


    While violence brings about headlines, guns are not the only cause for concern. Diseases – many of them preventable – are also a factor. Heart disease, lung disease, cancer, diabetes, strokes and renal disease are among the top 10 causes of death among Black men and Hispanic men, according to the Centers for Disease Control and Prevention. It makes sense that these causes also prominently figure in the deaths of hip-hop artists.

Gone before retirement

    • Heavy D (44) experienced a pulmonary embolism that led to his death.
    • Prince Markie Dee (52) of the Fat Boys passed away from congestive heart failure.
    • Phife Dawg (45) of A Tribe Called Quest, Tim Dog (46) and Biz Markie (57) all passed away from complications related to diabetes.
    • Guru (48) of Gangstarr, Bushwick Bill (52) of the Geto Boys, Hurricane G (52) and Kangol Kid (55) died from cancer.

A renewed focus on health

    • The occasion of celebrating 50 years of hip-hop provides a moment to reflect and honor some of the artists who contributed to the culture and are not here to celebrate this golden anniversary.
    • It’s also, perhaps, an opportunity to consider some of the outcomes of systemic barriers to health and wellness, such as access to affordable health care, varied dietary options and mental wellness resources.

How to overcome repetitive negative thinking through meditation

Wednesday, July 12, 2023

Maybe you ruminate on past mistakes, worry excessively about the future, or imagine worst-case scenarios?

Key Points: 
  • Maybe you ruminate on past mistakes, worry excessively about the future, or imagine worst-case scenarios?
  • Many people struggle with repetitive negative thinking, and this can have a serious impact on mental health and well-being.
  • As the coordinator of expertise in caregiving at the Centre for Research and Expertise in Social Gerontology and an associate member of the Centre for Study and Research on India, South Asia and its Diaspora, I would like to shed light on the negative impact of repetitive negative thinking on the mental and physical health of caregivers.

The devastating effects of repetitive negative thinking

    • Repetitive negative thinking (RNT) is a cognitive process characterized by persistent and intrusive contemplation on past events, commonly known as rumination, and apprehensions about future possibilities, often referred to as worries.
    • So, what would be the most effective strategy for managing repetitive negative thinking?
    • Research has demonstrated a negative correlation between RNT and mindfulness, implying that a low level of mindfulness can increase one’s susceptibility to RNT.

Journey to the present: The transformative power of mindfulness

    • There are two main styles of mindfulness practice: focused attention meditation and open monitoring meditation.
    • Focused attention meditation involves choosing a specific object, such as the breath, and bringing your full attention to it.
    • By deactivating the “default mode network,” focused attention meditation can help reduce this harmful type of thinking.

Reducing repetitive negative thinking: A breakthrough for caregivers

    • As part of our project, we will develop and examine an intervention targeted at reducing RNT in family caregivers.
    • Chronic stress is a common experience for family caregivers, and it can take a toll on their health and well-being.
    • A survey of caregivers found that the top areas of need for caregivers were emotional health (58 per cent) and physical health (32 per cent).
    • RNT is strongly associated with caregiver burden and predicts negative impacts on the physical and mental health of caregivers.

The ethics of recruiting international health-care workers: Canada’s gains could mean another country’s pain

Retrieved on: 
Tuesday, July 11, 2023

While the World Health Organization (WHO) declared the COVID-19 Public Health Emergency over in May 2023, Canada’s health workforce crisis has no end in sight.

Key Points: 
  • While the World Health Organization (WHO) declared the COVID-19 Public Health Emergency over in May 2023, Canada’s health workforce crisis has no end in sight.
  • As researchers with the Canadian Health Workforce Network, we see the roots of this crisis in poor workforce planning and the inadequate integration of immigrant health workers.

Canada’s health workforce crisis is more than a national issue

    • This voluntary code was agreed to by all member states in 2010.
    • Its key principles are ethical recruitment, a commitment to planning and international co-operation.

Why is the WHO Code important to reflect upon now?


    Recent Canadian health workforce reports identify the recruitment and integration of internationally educated health personnel (IEHPs) as part of the solution to the health worker crisis. The Parliamentary Standing Committee on Health held hearings on addressing Canada’s health workforce crisis, and the top four recommendations from its March 2023 report all referenced IEHPs:
    The Canadian Academy of Health Sciences report also offers “pathways forward to ease the health workforce crisis,” including improving the integration of IEHPs.

Provincial recruiting strategies

    • Saskatchewan launched an international health worker pool for Provincial Nominee Program candidates.
    • Manitoba started recruiting health-care workers directly from the Philippines.
    • Nova Scotia has recruited 65 refugees from Kenyan refugee camps who will be employed in the continuing care sector.

How compatible are these practices with the WHO Code?

    • However, recruiting health workers from countries on the WHO’s safeguard list without robust and reciprocal benefits for the countries sending them fails the ethical test.
    • Merging employment and refugee selection channels also suggests ethical concerns beyond health workforce issues, since refugee systems are based on the vulnerability individuals face, not their occupational compatibility.
    • Canada’s ability to approach self-sufficiency is limited by its lack of robust plans, and by the lack of data to support planning.

Voice support slumps in Essential poll; LNP leads in Queensland

Retrieved on: 
Tuesday, July 11, 2023

The last Essential Voice poll in June gave “yes” a 60–40 lead, in contrast to a 51–49 “no” lead from Resolve in a poll conducted at the same time.

Key Points: 
  • The last Essential Voice poll in June gave “yes” a 60–40 lead, in contrast to a 51–49 “no” lead from Resolve in a poll conducted at the same time.
  • The trajectories of Resolve and Newspoll are similar, while Essential has been the most friendly pollster for “yes”.
  • While Essential still has “yes” ahead, there is now a clear down trend in “yes” support in this poll.

Other Essential results: Labor leads by 51–44

    • In Essential’s two party measure that includes undecided, Labor led by 51–44 (52–42 last fortnight).
    • This is Labor’s narrowest lead in Essential since March.

Be sceptical of claims of existential crises for current opposition parties

    • But when the Coalition unexpectedly won the 2019 election, there were claims of an existential crisis for Labor.
    • Internationally, there were claims of an existential crisis for United Kingdom Labour after the Conservatives won a clear majority at the UK 2019 election, but Labour is leading in current UK national polls by about 20 points.
    • This is occurring despite the generational effects the CIS paper claims will damage the Coalition.

Last fortnight’s Essential poll

    • In last fortnight’s Essential poll, voters were asked to rate Albanese, Dutton and Greens leader Adam Bandt from 0 to 10.
    • Ratings of 0–3 were counted as negative, 4–6 as neutral and 7–10 as positive.
    • Relieving cost of living pressures had the highest score for not enough (75% not enough, 20% enough, 5% too much).

LNP leads in Queensland Freshwater poll

    • An April YouGov Queensland poll gave the LNP a 51–49 lead, although Resolve still had Labor ahead, but Resolve has skewed to Labor federally and in state polls since the May 2022 federal election.

AI is an existential threat – just not the way you think

Retrieved on: 
Wednesday, July 5, 2023

The rise of ChatGPT and similar artificial intelligence systems has been accompanied by a sharp increase in anxiety about AI.

Key Points: 
  • The rise of ChatGPT and similar artificial intelligence systems has been accompanied by a sharp increase in anxiety about AI.
  • Worries peaked in May 2023 when the nonprofit research and advocacy organization Center for AI Safety released a one-sentence statement: “Mitigating the risk of extinction from A.I.
  • And, in its most extreme version, this argument morphs into explicit anxieties about AIs enslaving or destroying the human race.

Actual harm

    • Yes, AI’s ability to create convincing deep-fake video and audio is frightening, and it can be abused by people with bad intent.
    • In fact, that is already happening: Russian operatives likely attempted to embarrass Kremlin critic Bill Browder by ensnaring him in a conversation with an avatar for former Ukrainian President Petro Poroshenko.
    • Cybercriminals have been using AI voice cloning for a variety of crimes – from high-tech heists to ordinary scams.

Not in the same league

    • The statement from the Center for AI Safety lumped AI in with pandemics and nuclear weapons as a major risk to civilization.
    • COVID-19 resulted in almost 7 million deaths worldwide, brought on a massive and continuing mental health crisis and created economic challenges, including chronic supply chain shortages and runaway inflation.
    • They have also changed the calculations of national leaders on how to respond to international aggression, as currently playing out with Russia’s invasion of Ukraine.

What it means to be human

    • AI in its current form can alter the way people view themselves.
    • It can degrade abilities and experiences that people consider essential to being human.
    • But the role of algorithmic recommendation engines is to reduce that kind of serendipity and replace it with planning and prediction.
    • If it does, educators will lose a key tool for teaching students how to think critically.

Not dead but diminished

    • But the increasingly uncritical embrace of it, in a variety of narrow contexts, means the gradual erosion of some of humans’ most important skills.
    • Algorithms are already undermining people’s capacity to make judgments, enjoy serendipitous encounters and hone critical thinking.
    • The fantastic anxieties around the coming AI cataclysm, singularity, Skynet, or however you might think of it, obscure these more subtle costs.

Banks put family violence perpetrators on notice. Stop using accounts to commit abuse or risk being 'debanked'

It happened when she was shopping for groceries with her kids, or refuelling the car.

Key Points: 
  • It happened when she was shopping for groceries with her kids, or refuelling the car.
  • That’s when she would discover her partner had cancelled the card or lowered the limit so she couldn’t buy essentials.
  • Ella* (not her real name) is one of about 1.6 million Australian women and 745,000 men who have experienced economic or financial abuse.

The highly disruptive tactics used by abusers

    • Perpetrators use a range of tactics, some of which are inadvertently enabled by bank products and services.
    • However, it may be possible to eliminate or reduce the need for these interventions with improved product design to prevent and disrupt abusers.

Taking action against perpetrators

    • It outlines steps banks can take to prevent their products being used as a weapon in domestic and family violence.
    • In banking, this means spelling out the bank’s rules and its expectations of customer behaviour in its terms and conditions.
    • These rules are the foundation of the contractual relationship with the customer and are relied on where there is a dispute.

Banks taking the lead

    • They will be the first Australian banks to signal to millions of bank customers they have a choice: abuse other customers and potentially lose access to their bank account, or behave with respect.
    • Implementation will be complex and the banks will need to proceed with caution.

Consequences for abusers who fail to stop

    • In this instance, there is the option of “de-banking” the customer which is not only a major inconvenience but also denies them access to an essential service.
    • It is instructive to examine the collective approach the banks have already taken to disrupt technology-facilitated abuse through payment descriptions.
    • It could also be informed by the Council of Financial Regulators’ de-banking policy recommendations on transparency and fairness measures.

Getting the public on board

    • Airlines make it clear jokes about terrorism are not okay, and patrons are ejected from sporting events for violence.
    • The widespread adoption of financial abuse terms and conditions and broad public communication will send a strong message to everyone with a bank account that financial abuse is unacceptable and has consequences.

60% of women and non-binary punters and artists feel unsafe in Melbourne's music spaces

Retrieved on: 
Tuesday, July 4, 2023

A new survey of 126 women and non-binary punters and artists working the music industry in Melbourne has found 60% of respondents feel unsafe in music spaces.

Key Points: 
  • A new survey of 126 women and non-binary punters and artists working the music industry in Melbourne has found 60% of respondents feel unsafe in music spaces.
  • The survey found sexual violence disempowers female music workers, deters non-binary communities from working in the industry, and discourages punters from going to gigs.
  • As Melbourne beats Sydney to became the nation’s most populated city in 2023, the epidemic of sexual violence may intensify in its urban music spaces.

The #meNoMore awakening

    • Studies have found grassroots venues and promoters in the United Kingdom need to implement changes to tackle sexual violence and work towards gender equality.
    • In January, it was announced the federal government’s new Revive cultural policy would establish a centre to address sexual harassment in the arts and entertainment industry.

A frequent violence

    • Respondents reported street harassment to and from venues, or were assaulted in commercially shared vehicles.
    • One third of the music punters reported an incident to venue staff or festival management.
    • Fearing unemployment in a highly competitive industry, they remain stoic victim-survivors in the boy’s club.

What’s next

    • The 2018 Melbourne Music Census found only 49% of staff in venues were trained in-house to deal with sexual harassment or assault.
    • Our study suggests all security staff should be provided with bystander training to prevent, detect and address perpetrators’ behaviour, and to refer victim-survivors to relevant authorities.
    • Too often, security staff have a reluctance to change routine practices, and many venues have a lack of female security staff.
    • There is poor collaboration between security companies and music staff, and limited funding for grassroots venues to conduct this training.

Vaccination in pregnancy greatly reduces risk of severe illness and death from COVID-19, and protects babies up to 6 months after birth

Retrieved on: 
Monday, July 3, 2023

From the early days of the pandemic, it has been evident that a COVID-19 infection in pregnancy can be serious.

Key Points: 
  • From the early days of the pandemic, it has been evident that a COVID-19 infection in pregnancy can be serious.
  • The data is stark: there is a five times higher risk of ICU admission and 22 times higher risk of maternal mortality due to COVID-19 infections in pregnancy.

Safety of COVID-19 vaccines in pregnancy

    • Despite the overwhelming data on the risks of COVID-19 infection in pregnancy, many have still been reluctant to get vaccinated, citing safety concerns.
    • We now have extensive evidence that shows COVID-19 vaccinations in pregnancy are safe, when given at any time during the pregnancy.

Infants protected by transfer of antibodies across placenta

    • Recent studies have shown that these IgG antibodies transferred to the fetus can remain in the baby for several months after birth.
    • One study showed 57 per cent of infants born to vaccinated mothers had detectable antibodies at six months.
    • Children younger than six months have the highest risk for severe outcomes associated with COVID-19 infections, including hospitalizations and death.

Benefits of a COVID-19 booster in pregnancy

    • Recently the World Health Organization recommended a COVID-19 booster during pregnancy if the last dose was over six months ago.
    • It is abundantly clear that COVID-19 infection in pregnancy carries considerable risk to the pregnant person and the fetus.
