Rain Is Coming to Burning Los Angeles and Will Bring Its Own Risks

    Rain is forecast to begin as soon as Saturday afternoon and to continue as late as Monday evening, says meteorologist Kristan Lund of the National Weather Service’s Los Angeles office. The area desperately needs the precipitation, but experts are warily monitoring the situation because rain poses its own risks in recently burned areas— most notably the potential occurrence of mudslides and similar hazards. “Rain is good because we’ve been so dry,” Lund says. “However, if we get heavier rain rates or we get the thunderstorms, it’s actually a lot more dangerous because you can get debris flows.”

    Fires do a couple of different things to the landscape that can increase the risk of burned material, soil and detritus hurtling out of control. When fires burn hot or long enough, they leave an invisible layer of waxy material just under the surface of the ground. This develops from decomposing leaves and other organic material, which contain naturally hydrophobic or water-repellent compounds. Fire can vaporize this litter, and the resulting gas seeps into the upper soil—where it quickly cools and condenses, forming the slippery layer.

    When rain falls on ground that has been affected by this phenomenon, it can’t sink beyond the hydrophobic layer— so the water flows away, often hauling debris with it. “All of the trees, branches, everything that’s been burned—unfortunately, if it rains, that stuff just floats,” Lund says. “It’s really concerning.” Even a fire that isn’t severe enough to create a hydrophobic layer can still cause debris flows, says Danielle Touma, a climate scientist at the University of Texas at Austin. Under normal conditions, trees and other plants usually trap some rain above the surface, slowing the water’s downward journey. But on freshly burned land there’s much less greenery to interfere; all the rain immediately hits the ground. [...]

    Fortunately, the rain should also help firefighters tame the blazes that remain active. The largest, the Palisades Fire, is currently 77 percent contained. The second largest, the Eaton Fire, is 95 percent contained. The Hughes Fire is third largest and only 56 percent contained. A fire can be fully contained but still burning. The containment percentage refers to the amount of the perimeter that has barriers that firefighters expect will prevent further spread.

WHAT IS THE COMMUNICATIVE APPROACH?

In the Communicative Approach, real communication and interaction is not only the objective in learning, but also the means through which it takes place. This approach started in the 70s and became prominent as it proposed an alternative to the then ubiquitous systems-oriented approaches, such as the Audiolingual method. That means that, instead of focusing on the acquisition of grammar and vocabulary (grammatical/linguistic competence), the Communicative Approach aimed at developing the learner’s competence to communicate in the target language (communicative competence), with an enhanced focus on real-life situations.

Should schools just say no to pupils using phones?

14th July 2024

Natalie Grice – BBC News

“I wouldn’t say it’s a good thing for a child never to have a smartphone. I think it’s part of a balanced life. You’ve got to live in your own time.”

These are not the words you might expect to hear from a teacher at a school that has never in its history allowed pupils under sixth form age to use a mobile phone on the premises.

But Sarah Owen, deputy head at Stanwell School in Penarth, Vale of Glamorgan, was simply expressing a personal opinion, rather than the school’s view about a young person’s wider life.

It is clear that she and the school have very firm opinions on what is best for children while they are on school grounds.

For Stanwell pupils in years 7 to 11, that has always meant no phones. Not in lessons, not in the corridor, not at breaktimes.

It is such a long-established rule that it presumably comes as no surprise to pupils and parents when they join the school, which is starting to seem as if it may have been ahead of a growing curve.

In the past few years, a number of schools across Wales and further afield have introduced total bans on mobiles. While Stanwell only asks pupils to keep phones switched off in their bags, others require the devices to be handed in at the start of the day.

Llanidloes High School in Powys is one which has implemented this policy in the past few years and Ysgol Penrhyn Dewi in St Davids, Pembrokeshire, followed suit at the start of this year.

Sarah Owen has been at Stanwell School since 2000 and says that there has always been a no phone policy in the school. For Sarah, it is a question not of trying to impinge on their students’ freedom, but of giving them vital time away from mobile life, for welfare as well as educational reasons.

“We genuinely believe this is in their best interests,” she said. “Phone addiction and screen addiction and scrolling, the loss of concentration, the loss of soft skills around listening and interacting with others, that’s something we need to be concerned about as a society generally.”

“We want children to be interacting with each other, having conversations, playing football, having those connections and interactions with other people.”

Sarah also believes it gives pupils relief from the possibility of being “photographed, filmed, mocked in some way – that’s not a nice way for children to live”. She said she wanted her pupils to have “some sanctuary from the anxiety of feeling so scrutinised and looked at”.

India's luxury airline Vistara flies into the sunset

Indian full-service carrier Vistara will operate its last flight on Monday, after nine years in existence.

A joint venture between Singapore Airlines and the Tata Sons, Vistara will merge with Tata-owned Air India to form a single entity with an expanded network and broader fleet.

This means that all Vistara operations will be transferred to and managed by Air India, including helpdesk kiosks and ticketing offices. The process of migrating passengers with existing Vistara bookings and loyalty programmes to Air India has been under way over the past few months.

"As part of the merger process, meals, service ware and other soft elements have been upgraded and incorporates aspects of both Vistara and Air India," an Air India spokesperson said in an email response.

Amid concerns that the merger could impact service standards, the Tatas have assured that Vistara's in-flight experience will remain unchanged.

Known for its high ratings in food, service, and cabin quality, Vistara has built a loyal customer base and the decision to retire the Vistara brand has been criticised by fans, branding experts, and aviation analysts.

The consolidation was effectively done to clean up Vistara's books and wipe out its losses, said Mark Martin, an aviation analyst.

Air India has essentially been "suckered into taking a loss-making airline" in a desperate move, he added.

"Mergers are meant to make airlines powerful. Never to wipe out losses or cover them."

To be sure, both Air India and Vistara's annual losses have reduced by more than half over the past year, and other operating metrics have improved too. But the merger process so far has been turbulent.

The exercise has been riddled with problems − from pilot shortages that have led to massive flight cancellations, to Vistara crew going on mass sick leave over plans to align their salary structures with Air India.

There have also been repeated complaints about poor service standards on Air India, including viral videos of broken seats and non-functioning inflight entertainment systems.

The Tatas have announced a $400m (£308m) programme to upgrade and retrofit the interiors of its older aircraft and also a brand-new livery. They've also placed orders for hundreds of new Airbus and Boeing planes worth billions of dollars to augment their offering.

But this "turnaround" is still incomplete and riddled with problems, according to Mr Martin. A merger only complicates matters.

Experts say that the merger strikes a dissonant chord from a branding perspective too.

Harish Bijoor, a brand strategy specialist, told the BBC he was feeling "emotional" that a superior product offering like Vistara which had developed a "gold standard for Indian aviation" was ceasing operations.

"It is a big loss for the industry," said Mr Bijoor, adding it will be a monumental task for the mother brand Air India to simply "copy, paste and exceed" the high standards set by Vistara, given that it's a much smaller airline that's being gobbled up by a much larger one.

Mr Bijoor suggests a better strategy would have been to operate Air India separately for five years, focusing on improving service standards, while maintaining Vistara as a distinct brand with Air India prefixed to it.

"This would have given Air India the time and chance to rectify the mother brand and bring it up to the Vistara level, while maintaining its uniqueness," he adds.

Beyond branding, the merged entity will face a slew of operational challenges.

"Communication will be a major challenge in the early days, with customers arriving at the airport expecting Vistara flights, only to find Air India branding," says Ajay Awtaney, editor of Live From A Lounge, an aviation portal. "Air India will need to maintain clear communication for weeks."

Another key challenge, he notes, is cultural: Vistara's agile employees may struggle to adjust to Air India's complex bureaucracy and systems.

But the biggest task for the merged carrier would be offering customers a uniform flying experience.

These are "two airlines with very different service formats are being integrated into one airline. It is going to be a hotchpotch of service formats, cabin formats, branding, and customer experience. It will involve learning and unlearning, and such a process has rarely worked with airlines and is seldom effective," said Mr Martin.

Still, many believe Vistara had to go − now or some years later.

A legacy brand like Air India, with strong global recognition and 'India' imprinted in its identity, wouldn't have allowed a smaller, more premium subsidiary to overshadow its revival process.

Financially too, it makes little sense for the Tatas to have two loss-making entities compete with one another.

The combined strength of Vistara and Air India could also place the Tatas in a much better position to compete with market leader Indigo.

The unified Air India group (including Air India Express, which completed its merger with the former Air Asia India in October) "will be bigger and better with a fleet size of nearly 300 aircraft, an expanded network and a stronger workforce", an Air India spokesperson said. 

"Getting done with the merger means that Air India grows overnight, and the two teams start cooperating instead of competing. There will never be one right day to merge. Somewhere, a line had to be drawn," said Mr Awtaney.

But for many Vistara loyalists, its demise leaves a void in India's skies for a premium, full-service carrier - marking the third such gap after the collapse of Kingfisher Airlines and Jet Airways.

It's still too early to say if Air India, which often ranks at the bottom of airline surveys, can successfully fill that void.

How to be a good flirt, according to science

By William Park, BBC 

Some people seem to be naturally gifted flirters, while many say it's a skill that holds them back. What sets the good and bad flirters apart and can you learn to be better at it?

In a crowded bar on a busy Friday night, one customer sits alone, waiting for their friend. The bartender, noticing the lonely patron, starts making small talk, asking about their day and making them feel welcome. Soon, the pair are hitting it off, the minutes fly by and the friend's tardy timekeeping is forgotten.

The bartender is charming, and the flirtatious conversation from this chance encounter puts the customer at ease. The customer is enjoying the attention – and why not?

"When someone flirts with you, you feel valued, and your perception of your desirability increases," says Gurit Birnbaum, a professor of psychology at Reichman University in Israel. In other words, being flirted with feels good. But can it also be good for you?

In the bar scenario, our bartender is unaware that the customer is in a relationship already. (Birnbaum points out that even if someone is in a relationship, flirting with others is to be expected. "With time, people tend to fantasise about other people. That's normal – it means nothing bad about the relationship.")

Yet there is something stranger about this blossoming interaction at a bar. While it might be the sort of interaction that could be taking place right now somewhere in the world, on this occasion, the bartender is computer generated and the whole interaction is taking place in virtual reality. It is occurring in a world dreamed up by Birnbaum.

Reflecting on the idea that people start to fantasise about others when in long term relationships, Birnbaum wondered whether fantasies could be used to help us regulate our more destructive desires. Would flirting with a virtual bartender make someone in a committed relationship more or less likely to flirt with someone in real life, she wondered? 

"I thought that this secure space [virtual reality] may help people control their desires, and help them maintain their current relationships," she says. "I can think about whatever I want, and then I'm done with it. And I don't have to act on those fantasies."

The virtual bartender looks a little uncanny – their movements are stiff and face a bit spooky. ("Virtual reality is much more immersive than what you can see in the video – so don't be disappointed," warns Birnbaum when sending me a screen recording.) They certainly couldn't be mistaken for a real person. But the speech is realistic, and in a five-minute interaction the conversation flows quite authentically.

After removing their headsets, people taking part in Birnbaum's experiment were then presented either with a conventionally attractive interviewer or an attractive stranger, who was actually a researcher posing as someone in need of help. The subjects who had flirted with the virtual bartender said they found the interviewer less attractive and spent less time helping the stranger than those who had a non-flirtatious conversation. It's as though, says Birnbaum, flirting at the virtual bar had inoculated them against a real-life temptation. Subjects also said they desired their real partner more after the flirtatious interaction at the bar.

Flirting with strangers while in a relationship could strengthen the bond between partners, suggests Birnbaum, but warns that this could be a slippery slope. Having a strong understanding of your own and your partner's flirting boundaries is essential, she says. The factors that might tip someone from harmless flirting into cheating can be subtle. "When people are exposed to norms of infidelity, for example if you know that your peers cheat on their partners, you are more likely to do so yourself," she says. This is called "contagious infidelity".

Birnbaum adds that there is a "constellation of personality traits" that make some people more resilient or more prone to infidelity. For example, more narcissistic people or people with attachment insecurities, are more likely to cheat than others. "We have to take into account so many factors in order to predict which seductive experiences would lead to infidelity," says Birnbaum.

While careful flirting might be good, many people consider themselves bad at it. In a poll of almost 7,000 male Reddit users, having poor flirting skills was the fifth most common reason (out of 43) men gave for being single.

Fortunately for those people, it might be possible to learn to be a better flirt. After three hours of flirt training, which involved learning techniques to appear more confident when speaking, a group of adult participants scored higher in flirting ability as well as in extraversion. 

Other flirting skills can be learnt, too. Expansive body posture – such as taking a wider stance, facing your interlocutor directly, and raising your head – increases romantic desirability for both men and women, perhaps because we associate taking up space with dominance and being expansive with openness. The effect is true in both a real-life speed dating scenario and online dating profiles. Considering that a brief encounter or a swipe of a photograph can make or break someone's chance of flirting successfully, maximising space might increase the chances of romantic success. 

Space maximisation is not something we are necessarily always conscious of doing, says T Joel Wade, a professor of psychology at Bucknell University in the US. "It's not like, oh, there's someone beautiful, let me spread out. It's just a natural behaviour." This nonverbal display of dominance can take the form of spreading out one's body or spreading one's possessions around to show comfort and belonging in a space, he explains.

In a poll of almost 7,000 male Reddit users, having poor flirting skills was the fifth most common reason (out of 43) men gave for being single.

While flirting can generally be an overt act, it can also be covert – actions that you might not necessarily think are flirting at all, explains Maryanne Fisher, a professor of psychology at St Mary's University in Canada. People mostly flirt with nonverbal signals, such as stroking their hair. Such behaviour is called "self-grooming", she says. "It's the idea of making myself more appealing for you." 

Differences in flirting techniques are true irrespective of sexual orientation. For example, men, people who described their identity as "masculine", and people who adhere to "masculine" gender roles are more likely to flirt overtly through the things they say and do regardless of who they are attracted to. Whereas, women, "feminine" identifying people and people who describe their gender role ideology as "feminine" are more likely to flirt covertly and nonverbally. 

If sexual orientation does not predict flirting styles, existing research, which has largely focused on normative sex roles and gender, may be "adequate to capture experiences of flirtatious behaviour among sexual minority individuals", write Jenn Clark, from the University of British Columbia in Canada, Flora Oswald from Pennsylvania State University in the US and Cory L Pedersen from Kwantlen Polytechnic University in Canada.

Other covert examples of flirting are "tie signs", which can be anything from initiating eye contact, hugging, giggling at jokes, to something that's more germ-related, like sharing food – which we don't typically do with a stranger.

In a non-flirting context, taking a partner's last name in marriage or wearing a wedding ring would be symbols of being tied to someone else. "Tie signs are often performed in a partner's absence to signal that you're taken," says Fisher. They can also be used to signal that someone else is not available. "If you want to signal that your partner is taken, the easiest way to do that is to perform an action. It is easier to put an arm around them than to tell someone else to back off," says Fisher.

But if flirtatious tie-signs are rebuffed, or if they're not very warmly received, these are signals that will tell potential mate poachers about the level of commitment in their romantic interest's existing relationship, and whether they have a chance. And of course, not demonstrating exclusive interest is among the most off-putting flirting behaviours, perhaps because we like to have the undivided attention of our dates. 

Subtle examples of flirting can be useful, adds Wade, because the flirter can also quickly shut down an interaction if they need to while having plausible deniability that there ever was romantic interest in the first place.

Generally, men overestimate romantic interest, perhaps mis-perceiving friendliness for attraction, and women underestimate it, which might be where the idea of the "friend zone" comes from. "The so-called false positive rate is so much different for heterosexual men than for heterosexual women," says Fisher. "Smiling, at least in Canadian culture, is a default, right? It's a way to deescalate situations, increase your perception of friendliness. But straight men see women smiling and they think, 'Oh, she's interested in me'."

Some businesses have taken advantage of the over-perception of flirting, says Fisher, by using women in frontof-house roles such as greeters at restaurants. "There have been court cases in the United States where women are saying they're being hit on because they're being told to smile and engage in this forced interaction that is being perceived in a sexual way," she says. And it is disproportionately women who are affected. 

So, it's worth asking: Was the virtual bartender really interested in the solo customer, or were they just being a good bartender?
