For centuries, our main sources of information have been pottery sherds, burial sites and ancient texts.

Key Points: 
  • For centuries, our main sources of information have been pottery sherds, burial sites and ancient texts.
  • But the study of ancient DNA is changing what we know about the human past, and what we can know.

Who were the Avars?


The Avars were a nomadic people originating from eastern central Asia. From the 6th to the 9th century CE, they wielded power over much of eastern central Europe.

  • The Avars are renowned among archaeologists for their distinctive belt garnitures, but their broader legacy has been overshadowed by predecessors such as the Huns.
  • Nevertheless, Avar burial sites provide invaluable insights into their customs and way of life.

Kinship patterns, social practices and population dynamics

  • We combined ancient DNA data with archaeological, anthropological and historical context.
  • As a result, we have been able to reconstruct extensive pedigrees, shedding light on kinship patterns, social practices and population dynamics of this enigmatic period.


We sampled all available human remains from four fully excavated Avar-era cemeteries, including those at Rákóczifalva and Hajdúnánás in what is now Hungary. This resulted in a meticulous analysis of 424 individuals. Around 300 of these individuals had close relatives buried in the same cemetery. This allowed us to reconstruct multiple extensive pedigrees spanning up to nine generations and 250 years.

Communities were organised around main fathers’ lines

  • Our results suggest Avar society ran on a strict system of descent through the father’s line (patrilineal descent).
  • In contrast, women played a crucial role in fostering social ties by marrying outside their family’s community.
  • Our study also revealed a transition in the main line of descent within Rákóczifalva, when one pedigree took over from another.
  • Our results show an apparent genetic continuity can mask the replacement of entire communities.

Future direction of research


Our study, carried out with researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany and at Eötvös Loránd University in Budapest, Hungary, is part of a larger project called HistoGenes funded by the European Research Council. This project shows we can use ancient DNA to examine entire communities, rather than just individuals. We think there is a lot more we can learn.

  • Now we aim to deepen our understanding of ancestral Avar society by expanding our research over a wider geographical area within the Avar realm.
  • Additionally, we plan to study evidence of pathogens and disease among the individuals in this research, to understand more about their health and lives.
  • Another avenue of research is improving the dating of Avar sites.

South Africa’s youth are a generation lost under democracy – study

Retrieved on: 
Thursday, April 25, 2024

But what is the real state of young South Africans – defined as people below the age of 34 – after 30 years of democracy?

Key Points: 
  • But what is the real state of young South Africans – defined as people below the age of 34 – after 30 years of democracy?
  • My recent research paper tracing 30 years of analysing youth marginalisation has found that youth in South Africa, who make up 34.3% of the population, have not fared well under democracy.

Measuring marginalisation

  • The survey recorded indicators like unemployment and level of education, as well as subjective views like feelings of alienation (not belonging in society).
  • The results were arranged on a scale of how far some young people had been pushed to the margins of society.
  • Comparing data from the 1992 and 2018 indices of youth marginalisation, the same proportion (5%) is clearly “lost” – scoring off the chart on virtually every indicator.
  • In terms of how much potential South Africa has squandered, they represent an entire generation of opportunity lost to the country.

Marginalised but not lost

  • As ever, they demonstrated their instrumental value to the adults controlling violence on various sides.
  • Those same adults and the media spoke of a “lost generation” – specifically, black, male, urban youth.

Marginalisation over time

  • In 1993, after first presenting to assembled youth organisations in 1992, we released the first iteration of the marginalisation index, Growing up Tough.
  • Despite the belief of our church sponsors that no-one is ever truly “lost”, that became the central category of the index.
  • In all, 5% of respondents scored high on all, or most, of the indicators in the 12 dimensions.
  • Most of the items in the index were later used by the Gauteng City Region Observatory in its early Quality of Life survey, allowing analysis of marginalisation across the entire Gauteng province population.
  • Only 0.3% of white youth (and 0.5% of Indian youth) showed signs of high marginalisation.

Thursday, April 25, 2024

Poetry by Wordsworth, Yeats and the only woman poet on our school curriculum, Emily Dickinson, became my sustenance.

Key Points: 
  • Poetry by Wordsworth, Yeats and the only woman poet on our school curriculum, Emily Dickinson, became my sustenance.
  • In my teens, I was deeply affected by the plight of Ann Lovett.
  • My most recent collection, Conditional Perfect (2019), offers a broader emotional range, including anger about many forms of oppression.
  • I recognise that poetry can indeed be “the lifeblood of rebellion, revolution, and the raising of consciousness”, as the author Alice Walker once stated.

Poetry for social change

  • In a world teeming with injustice, it is more urgent than ever to read (and write) poetry that engages with social realities and inequities.
  • Poetry, as Audre Lorde memorably stated, “is a vital necessity of our existence.
  • In our social media-driven era, where it often feels as if nuance is in jeopardy, it is timely to think about how poetry can embrace the political while not succumbing to the lure of rhetoric.
  • During the Arab Spring in 2010, Abu Al-Qasim Al-Shabi’s poem The Will to Life captured the emotions of Tunisian protesters in their struggle for democracy and change.

Writing political poetry

  • What are the skills writers need to enable them to speak out, while avoiding the didactic and over-simplistic meaning?
  • These are some of the questions my colleague, poet Eoin Devereux, and I are discussing today with special guest poet and renowned activist Sarah Clancy, in a unique online event for this year’s Poetry Day Ireland.
  • To quote American poet Joy Harjo:
    Remember the plants, trees, animal life who all have their tribes, their families, their histories, too.

Why don’t female crickets chirp?

Key Points: 
  • Why don’t female crickets chirp?
  • Among crickets, males are the only ones that make noise because females don’t have sound-producing structures on their wings.
  • But the female can hear very well and will come to a male who is signaling to her from some distance away.
  • You can learn to recognize them with a little practice, even if you never find the actual crickets.

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

Retrieved on: 
Tuesday, April 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?

What doesn’t kill you makes for a great story – two new memoirs examine the risky side of life

She questions whether women like herself – that is, the well-educated, sexually liberated beneficiaries of second-wave feminism – are really better off than their 1940s counterparts.

Key Points: 
  • She questions whether women like herself – that is, the well-educated, sexually liberated beneficiaries of second-wave feminism – are really better off than their 1940s counterparts.
  • But it isn’t quite the avant-garde art crowd looking for anonymous vaginas to cast in their latest 16mm masterpieces either.
  • Reconstructed from the travel diary the author kept at the time, the adventure is everything you could possibly hope for in a road trip – provided you (or your daughter) aren’t the one taking it.
  • Datsun Angel proves the old adage about time and tragedy making for champagne comedy.
  • It self-consciously situates itself as a cross between the substance-induced exuberance of Jack Kerouac and Hunter S. Thompson, and the provincially impassioned politics of Australian novelist Xavier Herbert.
  • For all her progressivism, there is a note of nostalgia ringing through Broinowski’s recollections.
  • Datsun Angel harks back to a looser – dare I say, more enjoyable – university experience.
  • The narrative promises, against well-intentioned assurances to the contrary, that what doesn’t kill you will, at the very least, make for a good story later on.
  • Broinowski goes part way towards acknowledging as much when she ends her postscript with: “If you’re male and reading this, kudos.

Detachment

  • Let me borrow one instead from the middle-aged Elmore Leonard fan whom Gordon encounters in the State Library Victoria early in the book: “dickhead”.
  • Yes, that about captures it: the protagonist of Excitable Boy is an unequivocal, grade-A dickhead.
  • Fortunately for Gordon (and dickheads more generally), the affliction may be chronic, but it need not be terminal.
  • This denotes an overriding structure or cohesion that I felt somewhat lacking from the work as a whole.
  • Detachment characterises much of Gordon’s storytelling as he kicks his younger self around the back alleys of Melbourne like a half-squashed can of Monster Energy Drink.
  • To be honest, I still haven’t made my mind up if Gordon’s aversion to Aristotelian catharsis is one of the book’s virtues or vices.
  • Detail has to be controlled by some overall purpose, and every detail has to be put to work for you.
  • Detail has to be controlled by some overall purpose, and every detail has to be put to work for you.
  • It is often difficult to gauge what overall purpose the details are serving in these essays, beyond fidelity to memory.

Many prisoners go years without touching a smartphone. It means they struggle to navigate life on the outside

Retrieved on: 
Friday, April 19, 2024

You’d be hard pressed to find any aspect of daily life that doesn’t require some form of digital literacy.

Key Points: 
  • You’d be hard pressed to find any aspect of daily life that doesn’t require some form of digital literacy.
  • We need only to look back ten years to realise how quickly things have changed.
  • In 2013, we were still predominantly buying paper bus tickets and using Facebook on a desktop computer.

Unfamiliar tech damaging confidence


Prison populations are getting older worldwide for a few reasons, including general population ageing, trends towards people entering prison at an older age, or staying in for longer. At the same time, Australian prisons remain highly technologically restricted environments, mostly for security reasons. We interviewed 15 Australians (aged 47–69 years) about their experiences of reintegration following release from prison.

  • They described feeling like a stranger thrown into a world where survival depended on their ability to use technology.
  • Regardless of their experiences before imprisonment, the rapid digitisation of daily functions that were once familiar to them rendered their skills and confidence irrelevant.
  • One former inmate said:
    There’s a significant gap […] for anybody who’s done, I’m gonna say, probably more than five to seven years [in prison].
  • There’s a significant gap […] for anybody who’s done, I’m gonna say, probably more than five to seven years [in prison].

Exacerbating recidivism

  • There’s concerning evidence around recidivism, risk of post-release mortality, social isolation, unemployment and homelessness.
  • Digital exclusion creates an additional barrier for those who are older, who already face a high risk of medical and social marginalisation.
  • A former prisoner said:
    Think about it, after being in ten years, well you think, okay, where do I start?

What can be done?

  • The interviewees provided suggestions for how such programs could be delivered and a keenness to engage with them.
  • They tended to focus on learning in environments free from stigma and judgement of their literacy level or histories, with hands-on experience and face to face support.
  • Interviewees favoured learning while in prison, with additional support available on the outside.
  • Based on the evidence, we can be certain this will encourage positive change for the 95% of Australian prisoners who will eventually be released.

Wild turkey numbers are falling in some parts of the US – the main reason may be habitat loss

Retrieved on: 
Friday, April 19, 2024

But people killed them indiscriminately year-round – sometimes for their meat and feathers, but settlers also took turkey eggs from nests and poisoned adult turkeys to keep them from damaging crops.

Key Points: 
  • But people killed them indiscriminately year-round – sometimes for their meat and feathers, but settlers also took turkey eggs from nests and poisoned adult turkeys to keep them from damaging crops.
  • Thanks to this unregulated killing and habitat loss, by 1900 wild turkeys had disappeared from much of their historical range.
  • Turkey populations gradually recovered over the 20th century, aided by regulation, conservation funding and state restoration programs.
  • We are wildlife ecologists working to determine why turkey populations are shrinking in portions of their range.

Fewer open spaces

  • While turkeys may appear at home in urban areas, their habitat is open forest – areas with sparse trees that allow near-full sunlight to reach herbaceous plants at ground level.
  • In 1792, naturalist William Bartram described the eastern U.S. as “Grande Savane,” or big savanna, a landscape with abundant wild turkeys.
  • The open spaces that are left often are not suitable for wild turkeys: They need a well-developed layer of vegetation at ground level that includes mainly wild flowers, native grasses and young shrubs and trees to provide cover for nesting and raising their young.
  • Turkeys can persist in these denser, shaded forests, but they don’t reproduce as successfully, and fewer of their young survive.
  • Over the past 50 years, populations of bird species that live in open forests and grasslands have fallen by more than 50%.

The roles of food, predators and hunting

  • For example, blame is often placed on more abundant predators that eat turkey eggs, such as raccoons and opossums.
  • But these predators probably are more abundant in part due to changes in turkey habitat.
  • This suggests that prescribed fire across the wild turkey’s range creates an environment that’s more favorable for turkeys than for their predators.
  • Lastly, some observers have proposed that the timing of hunting could be affecting turkey reproduction.

Creating space for turkeys

  • Land owners can help by managing for native grasses and wildflowers on their property, which will provide breeding habitat for turkeys.
  • We have produced podcast episodes that discuss which plants are valuable to turkeys and other wildlife, and how to promote and maintain plants that are turkey-friendly.

Cities with Black women police chiefs had less street violence during 2020’s Black Lives Matter protests

Retrieved on: 
Thursday, April 18, 2024

Black Lives Matter protests in cities with Black women police chiefs experienced significantly lower levels of violence – from both police and protesters – than cities with police chiefs of other racial backgrounds and gender, according to our newly published paper.

Key Points: 
  • Black Lives Matter protests in cities with Black women police chiefs experienced significantly lower levels of violence – from both police and protesters – than cities with police chiefs of other racial backgrounds and gender, according to our newly published paper.
  • After George Floyd’s death at the hands of Minneapolis police on May 25, 2020, the Black Lives Matter movement surged.
  • Most demonstrations were peaceful, but others were not, and city police chiefs had the job of dealing with street violence.
  • We do not yet know the specific way in which the leadership of Black women police chiefs translates into lower violence levels.

Illmatic at 30: how Nas invented epistolary rap – and changed the hyper-masculine world of hip hop forever

Retrieved on: 
Thursday, April 18, 2024

At the time, these lines were seen as just another gem in a long line of highly sophisticated, literary Nas lyrics.

Key Points: 
  • At the time, these lines were seen as just another gem in a long line of highly sophisticated, literary Nas lyrics.
  • In many ways a verbal successor to Nas, Lamar controversially won an actual Pulitzer prize for music.
  • Like Lamar, Nas is as highly esteemed in the street as he is in academic circles.

One Love breaks new ground

  • The Illmatic track One Love (1994) introduced the “epistolary narrative”, or written letter technique, to the rap genre.
  • As journalist, educator and author Dax-Devlon Ross explains, One Love contains “a series of prison letters set to song”, which “effectively began the epistolary sub-genre” of rap.
  • Notable advocates of the technique include one-time rival of Nas, Tupac Shakur, releasing Dear Mama a year after One Love.

Illmatic’s legacy

  • Released two years after One Love, Xzibit utilised rap’s newly established epistolary sub-genre to pen an emotive open letter to his young son.
  • The Foundation addresses themes prevalent in the male African American experience, such as lineage, loyalty, masculinity and the paternal bond.

Nas today

  • In recent years, Nas has reached a purple patch of creativity, and released a flourish of well received albums, including both the King’s Disease (2020) and the Magic series.
  • When brought into the running of “top five dead or alive” rap debates, Nas is often quick to deflect from comparison, stating that there “ain’t no best”.
  • As Nas said himself in 2022: “I probably don’t need a therapist because I have music.” It’s hard to think of another rapper of his generation who has opened up so many doors for the artform.
