Argentina Legalizes Abortion In Historic Senate Vote : NPR - 0 views

  • Argentina's Senate voted early Wednesday to legalize elective abortion, marking a historic shift in the heavily Catholic country that is the homeland of Pope Francis
  • the Senate passed the bill 38-29 with one abstention just over two weeks after the Chamber of Deputies, the lower house of Argentina's Congress, narrowly approved the measure.
  • "Today we took a huge step and we are getting closer to the Argentina we dream of. We are writing our destiny, we are making history."

  • Argentina joins a small group of Latin American and Caribbean countries that have legalized elective abortion, including Uruguay, Cuba and Guyana.
  • in mid-November. Fernández, who was elected in late 2019, has been vocal about legalizing abortion during his presidency and says he will sign the measure.
  • "Today we are a better society that expands rights to women and guarantees public health," Fernández wrote after the legislation passed.
  • In 2018 and 2020, people backing the legalization have sported green clothing and often held or worn green bandannas — a visual that has become linked with the movement.
  • Despite being largely illegal throughout the region, about 5.4 million abortions occurred annually in Latin America and the Caribbean between 2015 and 2019, the Guttmacher Institute reported.

The Women 'Fighting For Freedom' In Belarus : NPR - 0 views

  • Women have been at the forefront of protests against the regime of President Alexander Lukashenko, whose claim of victory in an August election is widely disputed. Holding flowers and flags, they gather weekly, risking arrest, harassment and beating by security forces.
  • The protests began after Belarus' disputed Aug. 9 reelection. Lukhashenko, who has been in power since 1994, claimed victory over Svetlana Tikhanovskaya, the wife of a jailed opposition figure.
  • "It's like at that time you realize that you are there not because you did something, not because you committed a crime. You are there because you are fighting for freedom. And the spirit of people, I mean, I was so amazed," Leuchanka said.

'Third World' Is An Offensive Term. Here's Why : Goats and Soda : NPR - 0 views

  • When an armed mob stormed the U.S. Capitol and took over the building on Wednesday, many Americans said that's what happens in "Third World" countries.
  • Everyone knows what they meant — countries that are poor, where health care systems are weak, where democracy may not be exactly flourishing.
  • But the very term "Third World" is a problem.
  • ...17 more annotations...
  • "this assumption about people outside of the 'First World' — that they lived really different lives, the assumption they were poor, they should be happy to eat every day. As if we don't have the same value as humans."
  • "I think it's a very antiquated and offensive term."
  • "There is no 'Third World.' There were the oppressed and the oppressors,"
  • The oppressors, he says, often took resources from the countries they colonized
  • Yet as Wednesday's events made clear, "Third World" is often the first term that pops into Westerners' minds when they try to characterize less well-off, troubled countries.
  • The idea of a world divided into three domains dates back to the 1950s when the Cold War was just starting. It was Western capitalism versus Soviet socialism
  • The "First World" consisted of the U.S., Western Europe and their allies. The "Second World" was the so-called communist bloc: the Soviet Union, China, Cuba and friends. The remaining nations, which aligned with neither group, were assigned to the "Third World."
  • "That's the 'Fourth World,' " Farmer says, referring to parts of the United States and other wealthy nations where health and economic problems loom large.
  • Because many countries in the Third World were impoverished, the term came to be used to refer to countries where poverty is rampant, where health care is inadequate, and where democracy does not flourish.
  • Who is to say which part of the world is "first"? Plus, the Soviet Union doesn't even exist anymore.
  • And it's not like the "First World" is the best world in every way. It has pockets of deep urban and rural poverty,
  • "Although the phrase was widely used, it was never clear whether it was a clear category of analysis, or simply a convenient and rather vague label for an imprecise collection of states in the second half of the 20th century and some of the common problems that they faced,"
  • "Being called a 'developing country' gives me a chance to improve." He hopes that one day India will go "a few steps beyond what 'developed countries' have achieved."
  • "I dislike the term 'developing world' because it assumes a hierarchy between countries"
  • "It paints a picture of Western societies as ideal but there are many social problems in these societies as well. It also perpetuates stereotypes about people who come from the so-called 'developing world' as backward, lazy, ignorant, irresponsible."
  • There are extremely wealthy people in poor countries, for example. Kenya has slums and neighborhoods where real estate prices rival any nation. It's part of a growing trend of income inequality around the world, Over notes.
  • So income levels tell you something — but not everything. Over would like to see classifications based on a combination of income and equality.

Uganda's Museveni Defends Violent Crackdown In Bid For 6th Term : NPR - 0 views

  • But just days away from an election on Thursday, the mood in the country is far more grave. Museveni is facing a formidable challenge from Robert Kyagulanyi, a singer-turned-politician better known by the stage name Bobi Wine.
  • Bobi Wine has electrified young people across Uganda. And Museveni, who has historically clamped down on anyone who poses a real threat to his power, has unleashed his security forces on him.
  • Uganda has already changed the constitution twice, allowing Museveni to remain in power. In the past week, his government shut down social media and his police chief warned that anyone causing trouble on election day "will regret being born."

  • According to the police procedures, if people are protesting, there is a way you handle it — but if now they overrun — overrun, for instance, a police station — you will have to stop it by using lethal fire. Rioting and attacking civilians and attacking property, it is something that we cannot accept.
  • [Ugandans] don't have to work hard. Now, that's a big struggle, which these know-it-all from [the] outside don't know, because in other parts of the world, people are pressured to work either by the environment, which is hostile, or by competition between man and man. But here, fools can survive.
  • It actually showed the lack of seriousness of those who [say] that you just go, just [leave power].
  • Yes, we are committed to the freedom of the press, but see, the press, especially the Western press, is arrogant. You don't want to learn; you know it all. Then you come on and impose your ignorance on our society.
  • How can we continue dealing with these arrogant ignoramuses? So if they change their attitude from arrogance to inquisitiveness and investigation, I'm very happy.

'Ballistic Fingerprint' Database Expands Amid Questions About Its Precision : NPR - 0 views

  • But now investigators are getting results in a matter of hours instead of months. And instead of just being a resource for prosecutors at trial, the NIBIN "match" is being used by investigators to generate leads, despite uncertainty about the precision of the match.
  • NIBIN was started in 1999 and has primarily been used by forensics examiners to testify at trial about the likelihood that a bullet was fired from a particular gun. But that's all changing now.
  • But some defense attorneys challenge the notion that the markings are unique, and the FBI says even expert testimony can't make that claim with certainty.
  • ...5 more annotations...
  • flawed firearms forensics have led to exonerations in the past.
  • In 2013 a Mississippi man's life was spared hours before his scheduled execution after the FBI said experts had overstated the science. In a note sent to the district attorney in that case, the bureau clarified that "the science regarding firearms examinations does not permit examiner testimony that a specific gun fired a specific bullet to the exclusion of all other guns in the world."
  • Puracal says using NIBIN as an investigative tool is less problematic than using it in court, but she still takes issue with its use.
  • That's because a NIBIN match, she says, can lead to cognitive bias in the investigators — a kind of tunnel vision.
  • Wilbon said they found three loaded guns in the car. No one had the required conceal-carry permits, and the people in the car had outstanding warrants.In the past the investigation may have ended with three people arrested and the guns placed in an evidence locker. But, because the Portland police have this new equipment, the casings were immediately entered into NIBIN. And because the Seattle police also use NIBIN, the ATF database indicated a match to shootings in Seattle.

New traumatic brain injury test is 'game-changing,' concussion experts say - ABC News - 0 views

  • In a world first, a newly authorized handheld device will allow doctors to detect traumatic brain injuries (TBIs) in under 15 minutes, potentially saving lives by dramatically shortening the time it takes to properly diagnose the issue.
  • Until now, health care providers have needed to rely on subjective measurements for TBIs, but we finally have a more objective tool to help evaluate patients.”
  • Unfortunately, many patients with mild TBI struggle to get an accurate and timely diagnosis, even as they grapple with ongoing symptoms. This ultimately results in delayed treatment.

  • Abbott’s new blood test may serve as an objective tool to help doctors triage TBI patients, because it relies on molecular signatures in the blood rather than on murkier clues, such as patient interviews.
  • often use a series of screening questionnaires, physical examinations and CT scans to take pictures of the brain in order to evaluate TBI. However, experts agree these techniques aren’t perfect and there is no objective way to reliably evaluate TBI.
  • Aside from reducing health care costs, it can save people from unnecessary radiation that has been shown to increase the risk of cancer.
  • Despite the benefits, experts agree that physicians cannot rely entirely on this diagnostic test, stating it will only serve to supplement clinical judgment.
  • "The game-changing innovation of having a tool like this is that, as it becomes more widely used, I believe we will identify more people with TBI that’s more subtle, that could be life-altering."

Depending on the extent to which you feel like you have the resources you need to cope with that. And that in large part may be dependent on whether or not you feel like you have others in your life you can rely on.
  • “We have evolved to be social creatures. For all the history of humanity, people have been in family structures, people have been in groups, we’re evolved to kind of crave and rely on that interaction with other human beings,”
  • “So when we don’t have that it’s a huge void in the way that we go about being human. This is something that has been kind of hard-wired into who we are as beings.”
  • people do at least have a wealth of options to stay connected. Texting, video calling or even the phone could potentially help avert the sense of isolation or loneliness, Khullar said.

Is addiction really a disease? | Life and style | The Guardian - 0 views

  • Treating addiction as if it is a learned pattern of thinking gives addicts the chance to stay clean
  • Many are coming to see addiction as a learned pattern of thinking and acting – a pattern that can be unlearned.
    • ilanaprincilus06
       
      Since it can be unlearned, are there some people just not willing to either help a person with addiction because of the societal norm that it is not always "completely unlearned"?
  • I recognise that the brain changes with addiction, but I see those changes as an expression of ongoing plasticity in an organ designed to change with strong emotions and repeated experiences.
  • ...5 more annotations...
  • I see addiction as an attitude or self-concept that grows and crystallises with experience, often initiated by difficulties in childhood or adolescence. Indeed, addiction is in some ways like a disease, but that’s only half the story.
  • Many take comfort in the disease label, because it helps them make sense of how difficult it is to quit. But for others, the disease label isn’t just wrong, it’s repugnant – it’s a rationale for helplessness and an obstacle to healing.
  • “I am not diseased… I don’t have a disease. I had past traumas, environmental factors and learned behaviours… I feel I have learned new things… new skills opened up… new pathways that were underdeveloped.”
  • Several studies have shown that a belief in the disease concept of addiction increases the probability of relapse.
  • If we can acknowledge that addiction is like a disease in some ways and very much unlike a disease in other ways, maybe we can stop trying to label it and pay more attention to the best means for overcoming it.

  • illusions not only reveal how visual scenes are interpreted and mentally reconstructed, they also highlight constraints in our perception.
  • ...9 more annotations...
  • Some of the most common types of illusory percepts are those that affect the impression of size, length or distance.
  • As visual processing needs to be both rapid and generally accurate, the brain constantly uses shortcuts and makes assumptions about the world that can, in some cases, be misleading.
  • These illusions are the result of visual processes shaped by evolution. Using that process may have been once beneficial (or still is), but it also allows our brains to be tricked.
  • if animals are tricked by the same illusions, then perhaps revealing why a different evolutionary path leads to the same visual process might help us understand why evolution favours this development.
  • Great bowerbirds could be the ultimate illusory artists. For example, their males construct forced perspective illusions to make them more attractive to mates.
  • When a male has two smaller clawed males on either side of him he is more attractive to a female (because he looks relatively larger) than if he was surrounded by two larger clawed males.
  • This effect is known as the Ebbinghaus illusion (see image), and suggests that males may easily manipulate their perceived attractiveness by surrounding themselves with less attractive rivals.
  • Deceptions of the senses are the truths of perception.
  • Visual illusions (and those in the non-visual senses) are a crucial tool for determining what perceptual assumptions animals make about the world around them.
