The good news, through all of this: Geospatial intelligence has offered valuable insights to help governments and organizations protect communities.

Key Points: 
  • The good news, through all of this: Geospatial intelligence has offered valuable insights to help governments and organizations protect communities.
  • Geospatial intelligence is the collection and integration of data from a network of technologies, including satellites, mobile sensors, ground-control stations and aerial images.

Disasters sudden and slow

    • For example, the National Hurricane Center actively monitors the location, formation and trajectory of tropical cyclones.
    • Detailed information on the timing, location and strength of a given hurricane helps officials distribute resources and personnel, as well as issue storm warnings and evacuation orders.
    • With climate change intensifying extreme weather events, there is likely to be a corresponding increase in threats to human safety and security.

Military and civilian logistics

    • In this way, geospatial intelligence represents an extension of the free press.
    • Another use of geospatial intelligence is in transportation, logistics and global supply chains.
    • Digital twins are being used in many civilian and military settings to improve decision making.
    • Digital twins have been highly effective in conflict settings by simulating weather and terrain to help militaries and peacekeepers develop and enact strategies.

Growing need

    • The need for geospatial intelligence is more important than ever.
    • Average temperature is projected to increase between 2 to 9.7 degrees Fahrenheit (1.1 to 5.4 degrees Celsius) by the end of the century.
    • Whether reconstructing the past, describing the present or anticipating the future, geospatial intelligence provides valuable information to help keep people and communities safe.

Is Rishi Sunak a lame duck? With MPs divided and rebelling, a sense of decline hangs heavy in the air

The UK system is different, but Rishi Sunak also appears to be struggling to get much done.

Key Points: 
  • The UK system is different, but Rishi Sunak also appears to be struggling to get much done.
  • The parliamentary timetable finished unusually early on a number of days in late June and early July.
  • So might Sunak also be called a lame duck?

Lame duck in Westminster

    • The Conservative parliamentary party is highly pluralistic, which makes it difficult to design and pass legislation at the best of times.
    • The last election in 2019 was fought and won almost exclusively on the issue of Brexit, but that issue no longer dominates the political agenda.
    • The party is now bogged down in its differences over climate change and online regulations.
    • As the election approaches, polling of this kind could drive attention towards Labour and its proposals for government.

There’s still time

    • Sunak still has a working majority of 62 seats in parliament so better party management would go a long way to helping his overall position.
    • And unlike a US president who has served two full terms, Sunak can (and clearly intends to) fight the next election.
    • He very much still has skin in the game and an incentive to perform better than he has so far.

These findings led to changes in NHS policy and guidelines beginning with the landmark report Changing Childbirth in the 1990s.

Key Points: 
  • These findings led to changes in NHS policy and guidelines beginning with the landmark report Changing Childbirth in the 1990s.
  • However, our recent research has revealed a disconnect between policy and the reality of how decision making happens.
  • This could help explain why women still say they feel ignored when they ask for pain relief during labour.
  • This is important to note beacuse black and Asian women in the UK are more likely to die in childbirth than white women.

Complexity of pain relief decisions

    • No one should be denied pain relief without explanation, but our study findings show how complex decisions about pain actually are.
    • One woman, who we called Fiona, requested opiate pain relief 18 times over an hour and a half.
    • The midwife asked what form of pain relief Fiona had in her previous labour and the nature of her current pains.
    • However, I asked for increased pain relief around 6.30am and repeatedly after that, and the midwife did not have a discussion with me about why it would be advisable not to have the pain relief until around 8.20am.
    • However, I asked for increased pain relief around 6.30am and repeatedly after that, and the midwife did not have a discussion with me about why it would be advisable not to have the pain relief until around 8.20am.

Midwives lead most decisions

    • When we examined how midwives initiated decisions, the majority (57%) were unilateral.
    • Midwives did occasionally offer explicit choice about whether a vaginal examination should take place, but only in early labour when they suspected there was no progress.
    • Otherwise, decisions about examinations tended to be pronounced, but always involved an explicit consent check beforehand.
    • Overall in our recordings, birth partners typically deferred to midwives and confined themselves to providing support for their partners.

The difficulty of providing choice

    • The fact that the length of labour is inherently uncertain does not help.
    • Delaying or deferring decisions can leave women feeling unheard during one of the most, if not the most, vulnerable times of their lives.

As we pass the half way mark in term 3, many students in Year 12 will be thinking more and more about their future.

Key Points: 
  • As we pass the half way mark in term 3, many students in Year 12 will be thinking more and more about their future.
  • So we have also developed a questionnaire to help parents and teachers talk to school leavers and understand their thoughts and feelings about careers and life after school.

Our research

    • This asked about their career aspirations, decision-making processes and intentions following school.
    • More than one third (33.8%) “agreed” or “strongly agreed” they “did not know what careers best suited them”.
    • Meanwhile 29% “agreed” or “strongly agreed” they often felt down or worried about selecting a career.

‘Overwhelming’

    • Riana*, who studied at university before working with a non-government organisation, said thinking about the next step beyond Year 12 “felt overwhelming”.
    • Meanwhile, Candice said she was aware of needing to make a pragmatic decision but also stay true to her interests.
    • Andrew also told us he sought advice from parents, teachers, university open days and student recruitment officers at universities.

Reaching for the familiar

    • This leads many students to reach for what is familiar.
    • After completing Year 12, Yasmin, lacked “a clear vision for my future career” and chose teaching “simply because it was a familiar job to me”.

How to have a supportive conversation

    • This helps them express their true feelings and make sense of all the information and choices.
    • When young people have these conversations with parents, teachers and career advisers, they have lower levels of career uncertainty and anxiety.

We all know this feeling, this tension between what you really want to do and what you really should, or shouldn’t, do.

Key Points: 
  • We all know this feeling, this tension between what you really want to do and what you really should, or shouldn’t, do.
  • It’s a psychological discomfort we feel when our behaviours and our values or beliefs do not match.
  • Not to worry, we can make that discomfort simply disappear with a good dose of #GirlMaths!

So what is #GirlMaths?

    • The reason #GirlMaths resonates so well with everyone and allows it to go viral is that we are very familiar with this type of thinking.
    • The mental gymnastics of #GirlMaths needed to justify cost-per-wear or cash-is-free is a perfect display of behavioural biases and heuristics, such as confirmation bias and denomination bias, being applied to everyday consumption decisions.

The psychology of decision-making

    • Our brain has a lot of decisions to make in a day and simply doesn’t have the power to scrutinise every little detail of every decision.
    • These shortcuts in our thinking may facilitate the decision making process, but they don’t always mean we make the most optimal decisions.

The financial and social costs

    • Gendered language operates to reinforce societal expectations with a particular gender and can promote stereotypes, biases and binary categories.
    • When stereotypes are reinforced within our own social circles, we are more likely to internalise these as part of our identity.
    • However, the convenience of these shortcuts in our thinking can obscure the hidden financial risks.
    • You may overlook the bigger picture of your financial health, and spend more than what you can afford.

The perils of #GirlMaths

    • While the term may initially come across as innocent fun, it’s crucial not to underestimate its potential harms.
    • Instead, let’s champion the use of inclusive language in finance that doesn’t perpetuate gender biases.

How old is the universe exactly? A new theory suggests that it's been around for twice as long as believed

Early universe observations by the James Webb Space Telescope (JWST) cannot be explained by current cosmological models.

Key Points: 
  • Early universe observations by the James Webb Space Telescope (JWST) cannot be explained by current cosmological models.
  • These models estimate the universe to be 13.8 billion years in age, based on the big-bang expanding universe concept.

Frequency and distance

    • The redshift of light is similar to the Doppler effect on sound: noises appear to have higher frequency (pitch) when approaching, and lower when receding.
    • Redshift, a lower light frequency, indicates when an object is receding from us; the larger the galaxy distance, the higher the recessional speed and redshift.
    • An alternative explanation for the redshift was due to the Doppler effect: distant galaxies are receding from us at speeds proportional to their distance, indicating that the universe is expanding.

Limitations of previous models

    • Research published last year proposed to resolve the impossible early galaxy problem using the tired light model.
    • However, tired light cannot satisfactorily explain other cosmological observations like supernovae redshifts and uniformity of the cosmic microwave background.
    • As with any model, it will need to provide a satisfactory explanation for all those observations that are satisfied by the standard cosmological model.

Mixing models

    • The approach of mixing two models to explain new observations is not new.
    • Albert Einstein resurrected the particle-like nature of light to explain the photoelectric effect — that light has dual characteristics: particle-like in some observations and wave-like in others.
    • Einstein believed that the universe is the same observed from any point at any time — homogeneous, isotropic and timeless.

New information

    • To defend the standard big-bang model, astronomers have tried to resolve the problem by compressing the timeline for forming massive stars and primordial black holes accreting mass at unphysically high rates.
    • However, a consensus is developing towards new physics to explain these JWST observations.

The enlargement will grow the association’s membership to 11, and increase its envisaged role as a geopolitical alternative to global institutions dominated by the west.

Key Points: 
  • The enlargement will grow the association’s membership to 11, and increase its envisaged role as a geopolitical alternative to global institutions dominated by the west.
  • The Brics five represent about 42% of the world’s population and more than 23% of world GDP.

Why are 'photo dumps' so popular? A digital communications expert explains

You’ve been to a “campout” with your school friends in someone’s back garden and taken a bunch of out-of-focus pictures on your digital camera.

Key Points: 
  • You’ve been to a “campout” with your school friends in someone’s back garden and taken a bunch of out-of-focus pictures on your digital camera.
  • The photos must be posted in a seemingly incoherent order and be “low effort” as opposed to being obviously edited.
  • This article is part of Quarter Life, a series about issues affecting those of us in our twenties and thirties.
  • Experts explain how to tell the difference Bed rotting: the social media trend the Victorians would love, especially writer Elizabeth Gaskell

The rise of the dump


    Instagram launched the “carousel” feature in early 2017, which enables users to include up to ten images in one post. But photo dumps didn’t grace our feeds until around late 2020. There are several potential explanations for the photo dumps trend:
    “Dump” implies that images have been haphazardly thrown together, but this understates the craftsmanship that goes into post curation on Instagram. Sociologist Erving Goffman argued that there’s no such thing as accidental self-presentation. All human interactions, whether they take place via social media or elsewhere, demand some level of craft and decision making.

The roots of the dump

    • People usually craft their physical photo albums into one of a number of themes, like recording an event or a trip, both of which have made their way to Instagram.
    • And both the dump and the album lose meaning if you aren’t known to the poster, akin to the consequences of a physical photo album being discovered at a rummage sale.
    • For example, albums benefit tremendously from the white space surrounding each carefully placed image, through which authors can craft a narrative of personal memory.

The future of the dump

    • Instagram, it seems, feels like a friend, familiar enough to grace with carefully curated, multi-part posts to tell stories about our daily lives.
    • And so, as we grapple with new questions, promises and concerns about emerging technologies such as AI, perhaps we are drawn to using the familiar things in more intimate ways.

In the aerospace strategy and national space policy, the government lays out how it intends to grow the domestic space sector by launching rockets and satellites and promoting Earth observation research.

Key Points: 
  • In the aerospace strategy and national space policy, the government lays out how it intends to grow the domestic space sector by launching rockets and satellites and promoting Earth observation research.
  • The documents indicate the government’s general priorities in “protecting New Zealand’s national interests” and the “responsible use of space”.
  • Space debris indeed poses long-term threats to space activities and Earth’s environment.
  • But sustainability should have a wider focus than the pollution of Earth’s orbital space.

What does sustainability in space mean?

    • But factoring in sustainability is usually an afterthought as we continue to compromise environmental, societal and cultural wellbeing for the sake of economic development.
    • Without clarity, it is difficult to develop techniques and targets for sustainability or to be held accountable for missing them.

Balancing priorities with values

    • But this could help us avoid the mistakes that have led to the current climate and biodiversity crises.
    • The way economic priorities are balanced with values through a holistic relationship with the Earth, sea and sky is already embedded in many Indigenous cultures around the world, including Māori.

Earth, its atmosphere and beyond

    • Are we thinking about our future activities just on Earth, or further afield, including planetary exploration and asteroid mining?
    • Closer to Earth, commercial satellite technology is now a well established method to observe our planet from space.
    • It helps to monitor weather and climate effects and provides crucial telecommunication services.

Society and culture

    • It is now threatened by increasing light pollution from mega constellations of satellites and accumulating space debris.
    • It means ensuring Māori voices are welcomed and respected at the decision-making stage and on what we choose to do in space.
    • Broadening our view of sustainability could be the difference between oppression and recognition of Māori interests in the domestic space sector.
