Facebook deserted by millions of users in biggest markets

Facebook has lost millions of users per month in its biggest markets. In the last six months, Facebook has lost nearly 9m monthly visitors in the US and 2m in the UK. Studies suggest that its expansion in the US, UK and other major European countries has peaked. In the last month, the world's largest social network has lost 6m US visitors, a 4% fall, according to analysis firm Socialbakers. In the UK, 1.4m fewer users visited in March, a fali of 4.5%. Users are also turning off in Canada, Spain, France, Germany and Japan, where Facebook is extremely popular.

Alternative social networks have seen surges in popularity with younger people. Instagram, the photo-sharing site, got 30m new users in the 18 months before Facebook bought the business. Path, the mobile phone-based social network founded by former Facebook employee Dave Morin, which only allows its users to have 150 friends, is gaining 1m users a week.

Facebook is still growing fast in South America. Monthly visitors in Brazil were up to 6% in the last month to 70m, according to Socialbakers, whose Information is used by Facebook advertisers. India has seen a 4% rise to 64m - still only a fraction of the country's population, so there is room for more growth.

As Facebook itself has warned, the time spent on its pages from those sitting in front of personal computers is decreasing fast because people now prefer to use their smartphones and tablets. Although smartphone minutes have doubled in a year, to 69 a month, that growth may not compensate for dwindling desktop usage.

Facebook will tell investors about its performance for the quarter. Wall Street expects revenues of about $1.44bn, an increase from $1.06bn a year ago. Shareholders will want to know how fast the number of mobile Facebook users is growing, and whether advertising revenues are increasing at the same rate. Facebook founder Mark Zuckerberg has created a series of new initiatives designed to appeal to smartphone users. One initiative, Facebook Home, is software that can be downloaded onto Android phones to feed news and photos from friends - and advertising - directly to the owner's locked home screen.

No one who speaks English has any difficulty understanding the meaning of a sentence like ‘It’s warm in here’. We all recognise that it is a comment on the temperature in some place or other. But why it is being said, and what the speaker wishes to convey by saying it, depends entirely on two things: the context in which it is said and what the speaker wants people to understand (...) The meaning of language depends on where it occurs within a larger stretch of discourse, and thus the relationship that the different language elements have with what comes before and after them. In other words, speakers and writers have to be able to operate with more than just words and grammar; they have to be able to string utterances together.

Our ability to function properly in conversation or writing depends not only on reacting to the context in which we are using the language, but also on the relationship between words and ideas in longer texts.

Words can also mean more than one thing, for example, ‘book’ (= something to read, to reserve, a list of bets, etc.), ‘beat’ (= to win, to hit, to mix, e.g. an egg, the ‘pulse’ of music/a heart) and ‘can’ (= ability, permission, probability – and a container made of metal). Notice that, in these examples, not only can the same form have many meanings, but it can also be different parts of speech.

With so many available meanings for words and grammatical forms, it is the context the word occurs in which determines which of these meanings is being referred to. If we say, ‘I beat him because I ran faster than he did’, ‘beat’ is likely to mean won rather than physically assaulted or mixed (though there is always the possibility of ambiguity, of course).

Slash and burn Brazil's rainforest is going up in smoke. Again.

As Brazil'S skyscrapers and silos rose, it seemed the most impressive quality of this 21st-century Latin American powerhouse was its ability to grow without trashing the environment. Just last year, Brasilia was boasting about a steep decline in deforestation in the Amazon rainforest, a feat that President Dilma Rousseff trumpeted as "impressive, the fruit of social change." What would she say now?

After nearly a decade of steady decline, forest cutting has spiked again in the world's largest rainforest. The nonprofit Amazon watchdog organization, Imazon, released a study reporting that deforestation at the hands of farmers and ranchers jumped 90 percent in the 12 months since April of last year. And since burning always follows felling, another 88 million tons of carbon dioxide and other gases hit the atmosphere—a 62 percent increase on the year.

For decades, Brazilians were told that ruin in the Amazon was the price of development. But recent research has imploded that assumption. A paper published by the National Academy of Sciences shows that continued deforestation threatens not just the trees but the progress and riches their removal were thought to guarantee. The paper bolsters an old theory by Brazilian climate scientist Eneas Salati, who argued that the Amazon actually produces half its own rainfall. The takeaway: remove too much of the forests and the Amazon could dry out. And more than the jungle is at stake. Reduced rainfall from forest cutting could dry up the water that powers hydroelectric dams, thus slashing Brazilian power-generating capacity by 40 percent by midcentury. It could also rob the food larder, cutting soybean productivity by 28 percent and beef production by 34 percent.

Brasilia quickly countered the environmental skeptics by saying that these are unofficial figures, noting that the National Space Institute is still crunching the satellite data. The government is still basking in last year's numbers: only 4,600 square kilometers of forests felled, a fraction of the 27,700 square kilometers lost in 2004. But the Rousseff administration would do well to heed the smoke signals. Even Brasilia admits that Brazil's continued rise to glory turns on the country's ability to stay green.

Study: Literary Criticism Is Still Overwhelmingly Male

By Zach Schonfeld

Women writers are all over the best-seller lists, but

literary criticism is still predominantly a male field.

That’s according to the latest numbers from the volunteer organization VIDA: Women in the Literary Arts, which works for gender and racial parity in the literary world. This year’s report covers prestigious publications like The New York Review of Books, which published 227 male reviewers last year but only 54 female reviewers, and The London Review of Books, which published 146 male critics and 44 women during the same period. The Paris Review “made great strides toward gender parity” in 2013, the report notes, but then slid and published substantially fewer women than men in 2014.

As The Guardian points out, those figures are especially striking when you consider that women are more avid readers than men in the U.K., where some of the biggest offenders are based.

The figures are not all disheartening. Major magazines like The New Yorker, The Atlantic and Harper’s all showed increases in the number of women published in 2014.

That data are valuable (without VIDA, the figures would likely go untallied), and the broader awareness even more so. Top editors likely know gender disparity is an issue, but they’re more likely to pay attention to it when an organization like VIDA is paying attention to them.

Climate change poses significant challenges to cattle farming, a sector vital to global food security. Among the most pressing concerns is the increasing frequency and intensity of droughts. Reduced rainfall diminishes pasture quality and availability, limiting feed for livestock and increasing water scarcity. This can lead to decreased animal growth rates, reduced milk production, and increased mortality rates. Moreover, prolonged droughts can contribute to desertification, shrinking available grazing land and forcing farmers to adopt costly alternative feeding strategies.

Beyond drought, other climate-related impacts include heat stress, which can significantly impact animal health and productivity. Rising temperatures can exacerbate heat stress, leading to decreased feed intake, reduced fertility, and increased mortality in livestock. Furthermore, extreme weather events, such as heavy rainfall and flooding, can cause infrastructure damage, contaminate water sources, and lead to the loss of livestock.

The cattle farming sector itself contributes to climate change through greenhouse gas emissions, primarily methane produced during animal digestion and nitrous oxide from manure management. Deforestation for pasture expansion also releases significant amounts of carbon dioxide.

To address these challenges, a multi-pronged approach is crucial.

• Genetic selection: Breeding programs focused on developing drought-resistant livestock breeds are vital. and heat-tolerant

• Sustainable feeding strategies: Implementing precision feeding techniques, improving feed efficiency, and exploring alternative drought-resistant forage livestock resilience. feed sources, varieties, such as can enhance

• Integrated farming systems: Integrating crop and livestock production, such as through agroforestry systems, can improve soil health, enhance water retention, and reduce greenhouse gas emissions.

• Technological innovations: Utilizing technologies such as precision livestock farming, remote sensing for pasture monitoring, and renewable energy sources can improve resource efficiency and reduce the environmental footprint of cattle production.

Furthermore, strong policy support, including incentives for sustainable farming practices, investments in research and development, and improved access to climate information services, are essential for the long-term sustainability of the cattle farming sector.

Addressing the challenges posed by climate change requires a collaborative effort involving farmers, researchers, policymakers, and consumers. By embracing innovative solutions, prioritizing sustainable practices, and fostering a collective understanding of the importance of climate-resilient livestock production, we can ensure a future when this vital sector continues to thrive while minimizing its environmental impact.

Why do birds sing so loudly in the morning in spring? It’s the ‘dawn chorus’

As spring begins, so does a fresh song at daybreak, unique to the season. Just before the sun rises, birds start singing their melodies, creating a chirpy symphony.

This phenomenon is known as the dawn chorus, and it’s special for a number of reasons: There are more birds singing at this time of year, and they also sing more often. This energetic burst of birdsong is often louder than usual too. The dawn chorus’ early morning explosion of sounds has even inspired multiple poems and songs.

“It's the epitome of spring,” says Jordan E. Rutter, an ornithologist at the American Bird Conservancy. After the long and cold winter, “all of a sudden you have this influx of so many beautiful birds coming back and singing.”

This harmony of birdsong at dawn happens during a fundamental time of the year. The dawn chorus is, in fact, mostly composed of birds of both genders singing to find a mate so they can breed (though males may sing more).

“There is such a large increase in quantity of song by individuals and the collective,” Rutter says. “These birds sing louder to literally be heard. They need to compete with each other as well, and the louder the better in regards to who is the most impressive mate.”

During this time, males also sing to assert their dominance and claim their territory. “Those songs are how they communicate to other males of the same species, or even just other birds and predators in general, and say, ‘This is my home,’” says Rutter.

In the United States and Canada, the dawn chorus can be heard roughly from March through May, when many bird species migrate there from their winter homes to breed. Peak dawn chorus times might depend on where you live, Rutter says. For example, April is peak for the southern U.S., but birds in Washington, D.C., will put on the best show in early May. (Alternatively, in the tropics, the dawn chorus can be heard almost any time of year, as many birds have a prolonged breeding season in those warmer climates.)

Why is it a ‘dawn’ chorus?

But why birds sing in the early morning is still “an open question,” says Mike Webster, an ornithologist at the Cornell Lab of Ornithology. “There's a lot of debate, and I don't think there's any consensus on exactly why it is that everything happens at dawn."

One hypothesis is that weather conditions at daybreak make it easier for birdsong to travel.

“In general, sound travels farther when the air is cooler and more dense. Sound also transmits more clearly (and very slightly faster) when humidity is higher so that details of the song do not degrade as much over distance,” says Heather Williams, a professor at Williams College who has studied the neuroscience of birdsong. She notes that wind may also impede sound transmission. “At dawn, the cooler air results in decreased winds at ground level, so coupled with the higher humidity, sound carries farther and more clearly, with less distortion.”
