Tuesday, July 4, 2023

In 2019, the World Health Organization (WHO) identified vaccine hesitancy as one of its top ten threats to global health.

Key Points: 
  • In 2019, the World Health Organization (WHO) identified vaccine hesitancy as one of its top ten threats to global health.
  • It appears this threat has only increased since the COVID pandemic.

A perfect storm for infectious diseases

    • In England, for example, childhood vaccination coverage generally plateaued from around 2011 and declined from around 2014.

      Rates of many infectious diseases declined at the height of the pandemic due to widespread social distancing measures, but cases have since started to increase.

    • For example, the number of countries with significant measles outbreaks rose by 50% between 2020–21 and 2022–23.
    • The combination of reduced vaccine coverage, overstretched healthcare systems, and the return to pre-pandemic levels of social contact have created a perfect storm for infectious disease rates to rise.

What drives vaccine hesitancy?

    • One of the main factors leading to hesitancy towards COVID vaccines specifically has been concern that the vaccines were developed too quickly.
    • However, we know that COVID vaccines are safe and effective.

Misinformation is a vector of disease

    • Over the course of the pandemic, we’ve seen widespread misinformation around the safety of COVID vaccines, which has unsurprisingly been linked to reduced confidence in the vaccines.
    • The problem with misinformation is how intractible it can be.

How do we increase vaccine confidence?

    • For example, a study from Japan predicted that vaccine hesitancy in relation to the HPV vaccine between 2013 and 2019 could lead to approximately 5,000 deaths from cervical cancer.

      To address vaccine hesitancy, we need to tackle the root causes.

    • Crucially, to increase confidence, we need to combat vaccine hesitancy caused by misinformation.
    • Otherwise, vaccine hesitancy will remain one of the greatest threats to global health for years to come.

ChatGPT took people by surprise – here are four technologies that could make a difference next

Monday, July 3, 2023

The astonishing functionalities of large language models (LLM) like ChatGPT were, just a few months ago, the epitome of cutting-edge AI.

Key Points: 
  • The astonishing functionalities of large language models (LLM) like ChatGPT were, just a few months ago, the epitome of cutting-edge AI.
  • They are now on course to be mere add-ons and plugins to our text editors and search engines.
  • The four we think are waiting in the wings are next-level GPT, humanoid robots, AI lawyers, and AI-driven science.
  • We chose these four because they were the ones that kept coming up in our investigations into progress in AI technologies.

1. AI legal help

    • The company recently said it would let its AI system help two defendants fight speeding tickets in real-time.
    • Connected via an earpiece, the AI can listen to proceedings and whisper legal arguments into the ear of the defendant, who then repeats them out loud to the judge.

2. AI scientific support

    • Machine learning, where an AI system improves at what it does over time, is being employed to identify patterns in data.
    • This enables the systems to propose novel scientific hypotheses – proposed explanations for phenomena in nature.
    • While AI cannot currently formulate hypotheses independently, it can inspire scientists to approach problems from new perspectives.

3. AutoGPT

    • Auto-GPT, an advanced AI tool released by Significant Gravitas, is already making waves in the tech industry.
    • Auto-GPT incorporates AI agents, or systems, that make decisions based on predetermined rules and goals.
    • Despite installation limitations, such an functionality problems when used with Windows, Auto-GPT shows great potential in various applications.

4. Humanoid Robots

    • Humanoid robots – those that look and move like us – have significantly advanced since the first Darpa Robotics Challenge in 2015, a contest where teams built robots to perform a series of complex tasks set by the organisers.
    • Figure AI, a company building humanoid robots for warehouse work, has already secured US$70 million (£55 million) in investment funding.
    • Humanoid robots offer advantages over other robots in tasks requiring navigation, manoeuvrability, and adaptability because in part, they will be operating in environments that have been built around human needs.

Taking the long view

    • The long term success of these four will depend on more than just computation power.
    • Humanoid robots could fail to gain traction if their production and maintenance costs outweigh their benefits.

School of last resort: how to fix NZ’s vital but ignored alternative education system

Retrieved on: 
Monday, July 3, 2023

After all, alternative education funding had remained static for its first decade of operation, after which it received only minor increases until this year’s government budget.

Key Points: 
  • After all, alternative education funding had remained static for its first decade of operation, after which it received only minor increases until this year’s government budget.
  • This is despite around 2,000 young people each year accessing alternative education as a school of last resort, having been excluded or disengaged from mainstream secondary schools.


These young people also reported they had developed their own learning goals, and that their schoolwork was set at the right level. Surely those are things we would wish for all young people, whether in alternative education or not.

A system under pressure

    • Many staff are not qualified teachers, but are tutors with community and youth work experience and training.
    • The success of their work was further highlighted in the Youth19 AE report also released last week.
    • At the same time, pressures on the system are growing, with more students entering alternative education with high and complex needs.

Out of sight, out of mind

    • In 1989, when the “Tomorrow’s Schools” reforms introduced competition between schools, vulnerable students soon became seen as liabilities because most struggled to meet the academic standards schools were judged on.
    • The 2019 Tomorrow’s Schools Independent Taskforce found competition had exacerbated ethnic and socioeconomic segregation.
    • Students suspended or excluded from their schools began turning up on the doorsteps of youth organisations, churches and iwi groups.

Focus and funding needed

    • Most Western countries have some system of catering for young people who need a different way of schooling.
    • We need to consider how schools can best serve all young people to give them the best chance to stay engaged.
    • In turn, this will require increased funding and support from the Teachers Council of New Zealand to register teachers in this setting.
    • But most importantly, we need to increase the focus on alternative education.

Expensive dental care worsens inequality. Is it time for a Medicare-style 'Denticare' scheme?

Retrieved on: 
Sunday, July 2, 2023

Private dental care is increasingly unaffordable, and millions of Australians go without the treatment they need.

Key Points: 
  • Private dental care is increasingly unaffordable, and millions of Australians go without the treatment they need.
  • The potentially avoidable costs to the health-care system and to people’s quality of life has led to increased pressure for a Medicare-style universal insurance scheme for dental care (Denticare) or the inclusion of dental care into Medicare.
  • Affordable and available dental care is crucial to addressing inequality in Australia.

Why wasn’t dental included in Medicare in the first place?

    • There is, however, little to no evidence on the extent to which the Whitlam government pushed for dental to be included or how much it was opposed by dentists.
    • It seems it was not on the agenda when Medicare was restored by the Hawke government.
    • Secondly, the provision of public dental health services – often linked to dental hospitals and dental schools – has long been seen (especially by Coalition governments) as the responsibility of states and territories.

A short history

    • This section gives the Commonwealth the power to legislate and fund these services but it’s not obligated to do so.
    • The Whitlam government was the first to provide national funding and direction to these state-based programs through the Australian School Dental Program.

The barriers to universal dental care

    • These figures don’t factor in the savings made to health-care costs due to preventable dental cavities and gum disease (estimated by the Australian Dental Association at $818 million per year) and reduced productivity.
    • The other approach is to reduce costs by limiting the number of people covered and/or the number and type of services covered.
    • Means testing access to Medicare Benefits Schedule items for dental care is risky; it could easily lead to means testing of access to other MBS items.

There’s more we can do

    • Researchers have described the Chronic Dental Disease Scheme (introduced by the Howard government) as as “the most expensive and controversial public dental policy in Australian history”.
    • As a 2012 analysis showed, it blew out its budget and did not result in dental health improvements.
    • It’s worth noting many of the preventive actions needed to address obesity (for example, encouraging breast feeding and limiting sugary beverages) will also improve dental health.

Did our mammal ancestors live alongside dinosaurs? New research hopes to end long-running debate

Retrieved on: 
Friday, June 30, 2023

It includes some 6,000 species who live in the oceans as well as on land.

Key Points: 
  • It includes some 6,000 species who live in the oceans as well as on land.
  • My team’s study used a new method to investigate this question and our findings may help settle this debate.

Estimating origins

    • The first is reading the fossil record - the oldest fossil in a group determines the date when it first evolved.
    • For placental mammals, there are a couple of fossils from around 65 million years ago, just after the mass extinction of dinosaurs.
    • Another way of estimating when groups first evolved is through molecular clock dating studies.
    • Two species that are similar in their genetic makeup probably have family trees that split from each other fairly recently.

Rocks or clocks?

    • For young lineages that evolved only a few hundred thousand years ago, this sampling rate may be quite high, because we have more fossils from younger rocks.
    • Younger rocks are more intact, and often closer to the surface.
    • But for older groups, the sampling rate may be quite low because geological processes degrade and destroy rocks and fossils over time.

The origins of placental mammals

    • The BBB model estimated the age of placental mammals to be within the Cretaceous period, around 70-80 million years ago – possibly up to 20 million years before the asteroid impact.
    • From an origin at the feet of dinosaurs, placental mammals have soared to become the most dominant animals on Earth.

Officially launched in July 2013, the National Disability Insurance Scheme (NDIS) reached full rollout in 2020.

Key Points: 
  • Officially launched in July 2013, the National Disability Insurance Scheme (NDIS) reached full rollout in 2020.
  • A decade later, Australians with disability, their families, advocates and support providers are waiting for the NDIS independent review and Disability Royal Commission findings, both due around October.

The goal posts

Canada takes first step to regulate toxic 'forever chemicals.' But is it enough?

Retrieved on: 
Thursday, June 29, 2023

These chemicals are found in food packaging, waterproof cosmetics, non-stick pans, stain- and water-resistant fabrics and carpeting, cleaning products, paints and fire-fighting foams.

Key Points: 
  • These chemicals are found in food packaging, waterproof cosmetics, non-stick pans, stain- and water-resistant fabrics and carpeting, cleaning products, paints and fire-fighting foams.
  • As environmental health researchers, we believe that the government needs to regulate and, eventually, stop the continued release of persistent toxic PFAS into the environment and also prevent the creation of any toxic replacements.

How do PFAS affect us?

    • The widespread use of these chemicals can be attributed to the strong chemical bond between the carbon and fluorine atoms that make up the backbone of PFAS.
    • However, that strong bond also leads to PFAS taking years, even decades, to break down in the environment.
    • For example, larger, older fish tend to contain higher concentrations of PFAS compared to smaller, younger fish.
    • A Canadian study found that at least 65 per cent of infants were exposed to PFAS in the womb.

Regulating PFAS

    • Canada also regulates another subset of PFAS called long-chain perfluorocarboxylic acids.
    • However, there are over 4,700 PFAS, and the Canadian and international regulations in place only cover a tiny fraction of the forever chemicals in the market.

Populations at highest risk

    • As public health scientists try to catch up with the industry’s unrestrained chemical production, some populations are put at heightened risk of PFAS exposure, including firefighters, pregnant women and Arctic Indigenous populations.
    • As emphasized in our report, Inuit living in Nunavik have some of the highest PFAS concentrations worldwide.
    • Some compounds measured in their blood were up to seven times higher than the concentrations measured in the rest of the Canadian population.

Towards better regulation

    • Yet, we know little about the impact of being exposed to multiple PFAS at a time.
    • Ongoing scientific studies are trying to understand the implications of mixtures on our health and how to regulate these forever chemicals accordingly.
    • The Canadian report is a necessary step to inform future regulations and stop the continued release of persistent PFAS in the environment.

The ‘Matthew effect’

    • If achievement gaps do widen as children develop, this would be evidence for what researchers call the “Matthew effect”.
    • This theory, first described by Canadian psychologist Keith Stanovich, proposes students who start with poor academic skills early in school make less progress over time compared with their higher-achieving peers.
    • (Or, as Matthew put it, “For whoever has will be given more, and they will have an abundance.

Our research

    • So results on one test can be directly compared to the next or the previous one.
    • Our research
      examined patterns growth in literacy and numeracy in two states.
    • We matched NAPLAN reading comprehension and numeracy results for each student from Year 3 through to Year 9.

Our findings

    • While surprising, our research aligns with findings from a 2014 meta-analysis of Matthew effects research in reading.
    • Our research is the first in Australia to build on these findings and examine reading and numeracy development in state-wide data using individual student scores across the NAPLAN years.
    • Although, our findings also indicate the highest achieving students do not make as much growth in NAPLAN as their lower performing peers.

But what does this mean for high achievers?

    • But our research suggests students who begin with poorer literacy and numeracy skills are supported by classroom teachers, and do make progress over time.
    • Perhaps the progress of high-ability students is not a high priority for schools once these students have attained the basic skills expected of their age group.
    • Further research in Australian schools is needed to identify the reasons for underachievement relative to potential for high-ability students.

Outer suburbs' housing cost advantage vanishes when you add in transport – it needs to be part of the affordability debate

Retrieved on: 
Wednesday, June 28, 2023

While housing is typically the biggest household cost, spending on transport is the second- or third-largest cost – and these costs are inextricably linked.

Key Points: 
  • While housing is typically the biggest household cost, spending on transport is the second- or third-largest cost – and these costs are inextricably linked.
  • There is research to suggest the cost difference between the inner and outer suburbs largely vanishes when both housing and transport costs are taken into account.
  • That’s because the home price is a single known figure, while transport costs add up over time.

The high cost of car-dependent suburbs

    • Using Australian Tax Office and Australian Bureau of Statistics data, the annual cost for households with one vehicle is around $9,500 per year, or nearly $800 a month.
    • However, many households, particularly in the outer suburbs, have more than one car.
    • It showed the outer suburbs of Australia’s capital cities were the most vulnerable because they depended on motor vehicles (not public transport) to get around.
    • Read more:

Why not consider housing and transport costs together?

    • The idea of combining housing and transport costs is not widespread.
    • It provides a better understanding of the affordability of each area by dividing housing and transport costs by income.
    • This study found that when housing and transport costs are both taken into account, there is little cost difference between the inner and outer suburbs.
    • Vancouver includes housing and transport costs in its Metro 2040 Plan.

What does this mean for planning policy in Australia?

    • This more holistic approach would produce better outcomes by reducing cost pressures on households.
    • Such an approach would likely result in higher housing densities closer to the CBD and other employment centres.
