More than 100 South African gold miners treated for smoke inhalation

JOHANNESBURG (Reuters) – Hundreds of South African gold mine workers were rescued and over 100 treated for smoke inhalation after an underground fire, the National Union of Mineworkers (NUM) said on Thursday

Safety is a huge issue in South Africa’s dangerous deep-level mines and a focus for investors. A spate of deaths at SibanyeStillwater’s gold operations, including a seismic event that killed seven miners in early May, has highlighted the risks.

In the latest incident, more than 600 miners were initially trapped after a fire broke out at a mine east of Johannesburg operated by unlisted Gold One, NUM said.

This comes almost two weeks after five miners died in an underground fire at a South African copper mine operated by unlisted Palabora Mining Company in Limpopo

Company officials could not immediately be reached for comment.

“As the NUM, we vehemently condemn this kind of incident as it is becoming a trend”, the union said in a statement.

Ancient dreams of intelligent machines: 3,000 years of robots

The French philosopher René Descartes was reputedly fond of automata: they inspired his view that living things were biological machines that function like clockwork. Less known is a strange story that began to circulate after the philosopher’s death in 1650. This centred on Descartes’s daughter Francine, who died of scarlet fever at the age of five.

According to the tale, a distraught Descartes had a clockwork Francine made: a walking, talking simulacrum. When Queen Christina invited the philosopher to Sweden in 1649, he sailed with the automaton concealed in a casket. Suspicious sailors forced the trunk open; when the mechanical child sat up to greet them, the horrified crew threw it overboard.

The story is probably apocryphal. But it sums up the hopes and fears that have been associated with human-like machines for nearly three millennia. Those who build such devices do so in the hope that they will overcome natural limits – in Descartes’s case, death itself. But this very unnaturalness terrifies and repulses others. In our era of advanced robotics and artificial intelligence (AI), those polarized responses persist, with pundits and the public applauding or warning against each advance. Digging into the deep history of intelligent machines, both real and imagined, we see how these attitudes evolved: from fantasies of trusty mechanical helpers to fears that runaway advances in technology might lead to creatures that supersede humanity itself.

Human like me? Avoid looking too perfect to those you hope to aid

While people in helping professions, such as doctors, might understandably try to lead by example and model a healthy lifestyle, research suggests this approach could have drawbacks.

In a recent study, both healthy-weight individuals and overweight people with concerns about their fitness reviewed the written profiles of several physicians, some of whom explicitly mentioned having personal habits like biking or maintaining a healthy diet. Overweight subjects tended to think such doctors would be more disapproving and were less inclined to see them, researchers found.

"I think we often have a false assumption that projecting as perfect an image as possible is the best way to fill the role of expert," says lead author Lauren C. Howe, a psychologist at Stanford University. "This fails to take into account the concerns people may bring into the mix, like worrying that an expert will look down on them for some quality they possess." She suspects this expert/novice dynamic plays out in other domains, such as in teacher/student relationships and mental health care.

Encouragingly, participants anticipated less disapproval from fitness-conscious physicians who also conveyed a nonjudgmental sentiment such as, "Everyone has their own definition of a healthy life" – and acknowledged that different people have diverse but worthy goals.

Migration flows in Latin America and the Caribbean

UNICEF Situation Report - September 2018

In the past two years, there has been an increase of Venezuelan citizens entering Brazil through the Roraima State border. According to Brazilian authorities’ estimations as of April 2018, the migration stock of Venezuelans in Brazil is of approximately 50,000 people most of them in Pacaraima and Boa Vista (Roraima state). Around 12 per cent are living in official shelters, while the majority are living either in private accommodations, spontaneous shelters or on the streets. The migratory influx is on the rise, putting extra pressure on the already overwhelmed basic services and limited capacity of local institutions. According to the Federal Police, up to 800 Venezuelan migrants may be crossing the border each day. Results from the Displacement Tracking Matrix (DTM) exercise conducted by IOM, indicate that nearly 50 per cent of respondents are expecting to stay in Brazil. Since February 2018, a voluntary relocation programme, known as the ‘interiorization plan’, was launched by the Brazilian Government offering migrants living in shelters the opportunity to move to other states. The programme includes transportation to other regions, housing and support for integration in host communities and labour market. At least 65 per cent of DTM’s interviewees were interested in participating in the interiorization process, particularly to Amazonas and São Paulo states.

Is it time you went on a social media detox?

In today's world, social media is central to our lives. It helps us to stay in touch with our friends, promote our work, and follow the latest news. How do these networks impact our mental and physical health?

A number of studies have linked social media use with increased levels of depression, anxiety, and isolation.

Social media lovers have twice the risk of depression, compared with their less enthusiastic peers.

Research has revealed that younger and older users alike are in danger of breaking under the pressure of unachievable standards of beauty and success.

Among young adult users, social media notably increases the incidence of anxiety and depression, according to the results of a sizeable study conducted in 2016.

In fact, the researchers saw that users who frequently checked their accounts had a more than twice as high a risk of depression than their less social media-oriented peers.

This may partly be due to the fact that social networks create an artificial need to be available 24/7, to respond to messages and emoji reactions instantly. But this attitude creates an unnecessary amount of low-key stress that takes its toll on our emotional well-being.

And, despite the fact that such platforms are supposed to enhance our sense of connectedness with other people, research has found that they actually have the opposite effect: they render dedicated users lonelier and more isolated.

However, this shouldn't really surprise us. The hyperconnectedness takes place at a superficial level, eliminating all of the extra elements that make communication more valuable and psychologically constructive.

Such elements include eye contact, body language, the possibility of listening for changes in our interlocutor's tone of voice, or the possibility of physical touch.

An over-active social media presence can leave its mark not just on our mental health, but also on our physical health — particularly by altering our sleep patterns.

Lastly, researchers have proven that our commitment to social media platforms can negatively affect our commitment to our own creative and professional lives in complex ways.

Exercising to relieve stress could do harm in long run without enough recovery time or a balanced lifestyle

Ed Haynes, founder and head trainer of Coastal Fitness Performance Training in North Point, says adding exercise to an already demanding and stressful life can end up doing more harm than good. “Our body can’t differentiate between different types of stresses,” he says. “My body doesn’t know the difference between exciting things like competing in some type of fitness competition or going on stage in front of 500 different people and, say, the fear, anxiety and nervousness of meeting my boss and thinking I’m going to get fired all day.”

A recent study published in The Lancet Psychiatry journal found that people can easily overdo things when it comes to exercise. In a large scale study, they found that the people who got the most benefit physically and mentally from exercise only worked out three to five times a week for between 30 and 60 minutes each time. Anything more than that tended to have a negative physical effect.
