    English has unarguably become the global default lingua franca. Indeed, English is spoken by more people for whom it is a second or additional language (L2) than by those for whom it is a first language (L1). It follows, then, that English is no longer used exclusively in communication involving L1 users but is increasingly employed in interactions in which neither participant uses English as their L1. It is estimated that only 4% of English language interactions in the world today contain solely L1 speakers. 

    The prominence of English as an international language has driven the ever-increasing demand for English language teaching (ELT) across the globe. However, the changing face of English presents a challenge for ELT practices to better reflect the current sociolinguistic reality. Traditional English as a foreign language (EFL) pedagogies which idealise the attainment of native-like competence are "neither responsive to nor consistent with the current profile of English".

    While in the past, learners of English may have been studying the language to communicate with L1 speakers, this is no longer the case for most learners who will be using English to interact with other L2 users. It is, therefore, critical that English language learners be equipped with an awareness of the current status of English and the skills necessary to communicate with users from a range of linguacultural backgrounds.

    The research design chosen for the study was a classroom based quasi-experiment. Quasi-experiments attempt to mimic true experiments in terms of rigour and structure but lack random assignment and a tight control of variables, making them more adaptable to real-world classrooms. While the resulting presence of confounding variables means inferring causality is much more problematic, this approach can still yield useful insights if findings are treated as suggestive as opposed to conclusive.

Noam Chomsky: The False Promise of ChatGPT March 8, 2023

By Noam Chomsky, Ian Roberts and Jeffrey Watumull

Dr. Chomsky and Dr. Roberts are professors of linguistics. Dr. Watumull is a director of artificial intelligence at a science and technology company. 


Jorge Luis Borges once wrote that to live in a time of great peril and promise is to experience both tragedy and comedy, with “the imminence of a revelation” in understanding ourselves and the world. Today our supposedly revolutionary advancements in artificial intelligence are indeed cause for both concern and optimism. Optimism because intelligence is the means by which we solve problems. Concern because we fear that the most popular and fashionable strain of A.I. — machine learning — will degrade our science and debase our ethics by incorporating into our technology a fundamentally flawed conception of language and knowledge. 


OpenAI’s ChatGPT, Google’s Bard and Microsoft’s Sydney are marvels of machine learning. Roughly speaking, they take huge amounts of data, search for patterns in it and become increasingly proficient at generating statistically probable outputs — such as seemingly humanlike language and thought. These programs have been hailed as the first glimmers on the horizon of artificial general intelligence — that long-prophesied moment when mechanical minds surpass human brains not only quantitatively in terms of processing speed and memory size but also qualitatively in terms of intellectual insight, artistic creativity and every other distinctively human faculty.


That day may come, but its dawn is not yet breaking, contrary to what can be read in hyperbolic headlines and reckoned by injudicious investments. The Borgesian revelation of understanding has not and will not — and, we submit, cannot — occur if machine learning programs like ChatGPT continue to dominate the field of A.I. However useful these programs may be in some narrow domains (they can be helpful in computer programming, for example, or in suggesting rhymes for light verse), we know from the science of linguistics and the philosophy of knowledge that they differ profoundly from how humans reason and use language. These differences place significant limitations on what these programs can do, encoding them with ineradicable defects. (…)

Less job mobility, lower productivity: the cost of cosy capitalism


Australians are changing jobs far less often than they did 50 years ago. Financial insecurity, debt and workplace barriers may be trapping workers in jobs – and helping entrench a low-productivity form of "cosy capitalism".


Fifty years ago work was different, wasn't it? Your first job on leaving school was at the bottom of the hierarchy – filing, making coffee or cleaning up the building site. If all went well you would move through the ranks and retire from the same firm or government department having achieved a middle or senior rank. That was before there was a gig economy, before computers allowed people to set up their own microbusinesses, and before the word 'precariat' had been coined.

What a pity the ABS has challenged this myth with hard data in their annual series on Job Mobility. In the 1970s on average 17 per cent of workers changed their employer or business in any one year: now only 8 per cent of workers do. We're staying much longer in our jobs. This series, going back to 1972, is shown below.

The trend is clearly towards less mobility, interrupted by the occasional economic shock – the 'recession we had to have' in 1990, and the pandemic in 2020.

One might have expected that increased female participation in the workforce would have seen more mobility, but women have followed the same trend as men: after the mid-1980s the male and female lines are indistinguishable.

Tracing cause and effect would involve a large research task, but there are some plausible explanations.

One is that the workforce has become more professionalised. There are fewer short-term unskilled vacancies, and fewer workers lacking any post-school skills. Work has become a more serious commitment by both employees and employers.

Another is that the cost to the individual in changing jobs has increased. This requires some explanation, because it is not immediately obvious.

Over the last half century there has been a significant fall in personal savings. Fifty years ago we were saving about 15 to 20 per cent of household income. Now our savings are between 2 and 5 per cent of income. This is partly a statistical artefact, because we are now accumulating savings in compulsory superannuation. But in terms of liquidity, such as ability to tide oneself over between jobs, it is a real constraint. The ABS Making ends meet survey shows that 27 per cent of households would be unable to raise $2,000 for something important within a week. We are carrying more personal debt, not because we are spendthrifts, but because some debt, particularly student debt, has been forced upon us, and runaway housing prices have increased the burden of mortgage debt.

To illustrate this fall in savings, we note that the days of long strikes are well behind us. Now a one-day strike is newsworthy. In times past strikes could stretch out for weeks and no industry was immune: in 1973 Sydney's Kings Cross strippers went on strike for up to two months.

Some workers now are restricted in their mobility by non-compete clauses. Many workers realise that shifting to another job probably involves going through a probationary period, with an uncertain outcome. The associated risk of unemployment has to be weighed against the lower risk of continued employment in a comparatively secure but less satisfying job.

We have allowed our economy to evolve into what may be called a pattern of cosy capitalism, where businesses have a compliant and stable (if not necessarily content) workforce. It works for business not only in terms of power in the labour market, but also in the broader economy. Consumption is sustained by innovations such as buy-now-pay-later schemes, heightening dependence on regular pay. People with no cash in reserve depend on car loans and are unlikely to risk taking low-cost-high-deductible home and contents insurance. It's all very convenient for the finance sector.

Cosy capitalism is low-productivity capitalism, because it throttles the dynamics of capitalism. Workers become trapped in low-productivity jobs, and entrepreneurs trying to establish new businesses find it hard to attract labour. Existing firms have little incentive to boost labour productivity if they feel assured that they can hang on to workers in low-productivity jobs and don't have to increase their pay. 

There are certain things governments can do to boost productivity that involve removing friction in the system. The government has committed to banning the unjustified use of non-compete clauses, for example. State governments could make it easier for people to move by abolishing real-estate transfer taxes and replacing them with land taxes. The Commonwealth could boost JobSeeker payments and remove some of the spend-down provisions in its asset test, shifting its design from a scheme of distributive welfare to one of income insurance. More could be done to allow for transfer of long service leave and sick leave between employers.

Such policies would boost productivity, but they wouldn't be met with many thanks from those who do well for themselves in our pattern of cosy capitalism. Business lobbies may speak for the short-term interests of existing business, but not for the interests of business in its wider sense. The distinction is important.

    When the covid-19 pandemic forced in-person classroom instruction to go virtual, students suddenly needed to have their own laptops or tablets in order to interact with teachers and complete assignments. In the United States (U.S.), federal pandemic funding was used to address the digital divide – the gap between students and families who had their own tablets, computers and high-speed internet, and those who did not.


    While most schools resumed in-person classes by 2021, many of them continued to rely heavily on online platforms and apps to help their students do their work. Today, however, more and more U.S. schools are trying to establish clearer expectations about when technology should be used, for what purpose and at what ages. Instead of treating screens as the default tool for instruction, some schools are directing teachers to use laptops only when the technology adds clear instructional value.


    In fact, the distinction between passive consumption and purposeful use is increasingly shaping school policy. Updated policies also reflect an emerging emphasis on age-appropriate screen use. For older students, technology may remain central to learning, particularly when students are using it to program, analyze data, model complex systems and critically evaluate information. Younger children, meanwhile, should have sufficient opportunities for play, conversation, movement and hands-on, “unplugged” learning, without screens.


    The issue is not whether students spend more or less time using technology. It is whether the time they spend with technology helps them build understanding, solve problems, think critically and make informed decisions. The technology itself is not what improves learning. What matters is how teachers use it to engage students in deeper thinking.

Reading as an Active Process


Many people assume that reading is simply the ability to recognize words and understand their literal meanings. However, proficient readers know that comprehension is a far more sophisticated process. Rather than passively absorbing information, skilled readers actively construct meaning by interacting with the text, questioning the author’s ideas, and integrating new information with their existing knowledge.

One of the most effective reading strategies is prediction. Before beginning a text, readers examine titles, headings, visuals, and introductory paragraphs to anticipate its content and purpose. These predictions are continuously revised as new information emerges, demonstrating that reading is a dynamic rather than linear process.

Another essential strategy is monitoring comprehension. Expert readers constantly evaluate whether they understand what they are reading. When comprehension breaks down, they employ repair strategies such as rereading, slowing their reading pace, consulting context clues, or summarizing key ideas before moving forward. Less experienced readers, by contrast, often continue reading despite confusion, which limits their overall understanding.

Critical reading extends beyond comprehension     encouraging readers     evaluate the credibility, assumptions, and intentions     a text. Instead of accepting every statement as factual, critical readers consider the author’s perspective, identify possible bias, and compare the information with other reliable sources. In today’s digital environment, where misinformation can spread rapidly, these analytical skills have become increasingly important.

Furthermore, effective readers recognize that every text is written for a particular audience and purpose. A scientific article, a newspaper editorial, and a social media post all require different reading approaches. Adjusting one’s strategy according to genre, purpose, and context enables readers to extract relevant information more efficiently.

Finally, reading should be viewed as an ongoing dialogue between the reader and the author. Meaning does not reside solely in the words printed on the page; instead, it is constructed through the interaction between textual evidence, the reader’s prior knowledge, cultural background, and personal experiences. Consequently, two readers may develop different—but equally valid—interpretations of the same  text, provided that their conclusions are supported by evidence.

Ultimately, becoming a proficient reader involves much more than increasing reading speed. It requires conscious strategy use, critical thinking, and a willingness to question, reflect, and make meaningful connections throughout the reading process.
Study these sentences, from text 2, and decide if they are true ( T ) or false ( F ), according to structure and grammar use.

Digital Communication and Human Interaction


Advances in digital technology have transformed the way people communicate. While social media platforms, messaging applications, and video conferencing tools have made communication faster and more accessible, many researchers argue that they have also altered the quality of human interaction.

A leader in the study of longevity is returning to UCLA Health


Renowned geroscientist and computational biologist Steve Horvath, PhD, is returning as a professor in the David Geffen School of Medicine at UCLA on July 1, after 4 1/2 years in the biotech industry. Previously, he was a full-time professor of Human Genetics and Biostatistics at UCLA for 22 years.

Geroscience is the modern term for the biology of aging. Dr. Horvath, who was born in Germany, is internationally known for his research into the aging process and, in particular, epigenetics, how the environment influences our genes, affecting a person's longevity.

His groundbreaking research, which he began at UCLA in 2011, looked at the "epigenetic age" of more than 13,000 DNA samples of people from the U.S. and Europe, determined from the chemical modifications of their DNA (also called DNA methylation).

People whose epigenetic age was higher than their chronological age were shown to be at an increased risk of death from all causes. From this, Dr. Horvath developed the "epigenetic clock," a way of measuring biological aging and mortality risk.

"The universal mammalian methylation clock was really a UCLA triumph — a true team effort," said Dr. Horvath, who received the 2026 Luminary Award at the Precision Medicine World Conference. That project, part of the international Mammalian Methylation Consortium that Dr. Horvath led, drew on collaborators across UCLA, including Jason Ernst, PhD; William Yang, MD, PhD; Ebru Erbay, MD, PhD; Karen Sears, PhD; and Ren Larison, PhD.

Aging is a growing field of study and the Division of Geriatrics is a research leader.

"Aging happens at the cellular level — every tissue in the human body shows signs of aging," explained Arun S. Karlamangla, MD, PhD, chief of the UCLA Division of Geriatrics. "The epigenetic profile is affected by stresses in life. As we age, these stresses change DNA functionality. Dr. Horvath's research showed that these changes can be quantified and used to predict a person's lifespan."

None of us has control over the DNA we're born with, but we do have some control over how long we live.

"The epigenetic clock is one window into biological aging, but it doesn't capture everything, and plenty of well-established factors influence how long and how well a person lives," said Dr. Horvath. "The strongest evidence is for the basics: not smoking, maintaining a healthy weight, a sensible diet, regular physical activity and good sleep."

Dr. Horvath has run the test on himself and by the epigenetic clock, he is about three years younger than his chronological age of 58.

New medications also show promise for improving longevity, he said. "There's active research interest in newer GLP-1 receptor agonists — e.g., the Ozempic/Wegovy class — which are reshaping how we think about metabolic health," said Dr. Horvath, adding that the same is true for anti-inflammatory and antifibrotic drugs.

Dr. Horvath's epigenetic clocks have become standard tools across aging research, used by teams worldwide to test what actually changes biological aging. 

They have been applied in the randomized DO-HEALTH trial, where omega-3, vitamin D and exercise modestly slowed epigenetic aging in adults older than 70; in the Women's Health Initiative, where faster epigenetic aging tracked with later cognitive impairment and dementia; and in studies of cardiovascular disease and mortality. This kind of population-level application aligns closely with the Division of Geriatrics' emphasis on healthy, independent life expectancy.

Dr. Horvath's research has also shown that the cells of different organs age at different rates. For instance, the liver ages faster than other organs, he said, particularly in the case of people with obesity.

Another discovery was that the blood and brain tissues of human males age faster than those of females, which might be the reason women live longer on average than men across all cultures and countries.

Leading in aging research

The study of aging at the UCLA Division of Geriatrics focuses on understanding the epidemiology of age-related conditions such as frailty, cognitive impairment and dementia, and improving the delivery of compassionate, comprehensive care to older adults.

Dr. Horvath's return to UCLA will bolster the department's role in aging research by translating his cellular research to clinical trials, said Dr. Karlamangla.

"We want to be pioneers in all three aspects: cellular research, clinical and population-level research, and health services and implementation research," Dr. Karlamangla said. "We are one of the pioneers in clinical innovation for the delivery of healthcare to older adults," he said, an approach that is called bench to bedside.

Life expectancy is important, but even more important is good health, which is necessary for independence, Dr. Karlamangla emphasized. This is referred to as healthy life expectancy, or independent life expectancy.

New work at UCLA

Along with serving as a professor, Dr. Horvath will return to UCLA Health as director of aging biology research in the Department of Medicine, working across 11 divisions. In this way, he will work directly with doctors to apply aging research to their patients. The move into the Department of Medicine is deliberate: his focus now is translating discoveries from aging biology into care for patients.
"What I'm most looking forward to in returning to UCLA is the people and the collaborative environment," said Dr. Horvath. "UCLA has remarkable strength across medicine, computational biology, stem cell biology, and the basic science of complex diseases, and being back in that setting with former colleagues and future students is what excites me most.

"It feels like the right place to do the next phase of this work: helping to translate findings from aging biology into the clinic."

More than 20 children killed in DR Congo school fire

At least 24 schoolchildren have died in a stampede as they tried to flee a fire that engulfed two schools in rebel-held Bukavu in the eastern Democratic Republic of Congo, officials there have said.
Adults are also reported to have died in the fire and there are fears that the death toll could rise further in the densely populated Kadutu commune.
Survivors have been taken to nearby hospitals, and footage of the scene shows children lying on hospital floors in pain.
Some 300 houses have also been destroyed in the fire, the cause of which is unknown.
Rebel?appointed authorities released a provisional death toll of 24 on Thursday evening, confirming previous reports, but there are fears that more people may have died.
Pictures circulating on social media show young children lying motionless on the ground.
A witness quoted by Reuters news agency said the fire had been put out by afternoon but smoke was still rising from rubble and corrugated metal.
Bukavu, the capital of South Kivu province and one of DR Congo's most crowded hillside cities, was captured by M23 rebels in February last year.
Meanwhile the government in Kinshasa released a statement on X, without specifying numbers of casualties.
"The Ministry of National Education and New Citizenship expressed deep sorrow over the deadly fire," it said.
"With several lives lost and many injured, the toll remains provisional. The minister offered condolences, affirmed solidarity with families, and ordered assessments of affected schools to ensure learning continuity."
The tragedy follows a similar fire in Kinshasa last weekend, where residents died in a stampede at a wedding banquet hall.
In response, the government has ordered strict safety measures and deployed teams nationwide to enforce standards at public gathering places.

World's largest intelligent container ship sets sail



The delivery of the nation's first and the world's largest intelligent container ship powered entirely by electricity marks the transition toward a greener and more intelligent future by China's shipping industry, experts said.


Following the successful completion of various tests, the vessel, named Ning Yuan Dian Kun, was delivered in Ningbo, Zhejiang province, on Wednesday.


"From the initial project approval to the final delivery, the vessel showcased the full life-cycle development of zero carbon ships, characterized by pure electric propulsion, autonomous navigation and high operational efficiency, achieved by China's shipping industry," said Ma Hongmeng, a senior engineer at Shanghai Merchant Ship Design and Research Institute and the person in charge of the intelligent container ship.


According to Ma, the ship is proof that China's coastal container transportation segment is entering a new era marked by zero-emissions, intelligent operations and high efficiency, a prerequisite for achieving carbon neutrality and shipping energy transformation. 


With a capacity of over 740 twenty-foot equivalent units, the vessel was independently developed and designed by SDARI. Its electric propulsion system was provided by Shanghai Marine Equipment Research Institute. Both companies are subsidiaries of China State Shipbuilding Corp.


"Independently developed by SMERI, the innovative electric propulsion system has undergone maritime navigation tests, which fully proved its reliability, superiority and adaptability," said Wu Guodong, a senior engineer at the institute.


He added that with all performance indicators meeting expectations, the technological breakthrough from design to application highlighted China's leading position in pure electric ship power system integration worldwide, and laid a solid foundation for the transformation of China's shipping industry to a greener and carbon neutral one.


With a length of 127.8 meters and a width of 21.6 meters, the ship has been tailor-made for Ningbo Ocean Shipping Co and will run on the coastal shipping route between Ningbo and Jiaxing in Zhejiang province.


A senior official from the Ningbo Maritime Safety Administration said that due to the distinctive features of new-generation intelligent vessels, a dedicated service team has been established to provide comprehensive support. The team will conduct continuous tracking and precise assessments throughout the entire process — from design and construction to navigation — ensuring a thorough grasp of the vessels' technical characteristics and effective control of operational risks.


The vessel is equipped with 10 container-shaped power units with a total power supply capacity of about 19,600 kilowatt-hours.


"This allows the ship to achieve zero-emission and zero-noise green operation throughout the entire voyage, while perfectly adapting to the practical operational needs of coastal container transportation," Ma said.


Wang Ting, captain of Ning Yuan Dian Kun, also confirmed this view. "Compared with traditional fuel-powered vessels, the most noticeable change in a fully electric seagoing ship is the lack of noise. In the past, the engine room would be filled by the roar of the main engine, whereas voyages nowadays are almost silent. This creates a more relaxed working environment and allows crew members to concentrate better on operations — a significant improvement brought about by green energy," he said.


He added that in terms of power response, the torque output of electric propulsion motors is linear and instantaneous. Acceleration and deceleration are smooth and highly responsive, with virtually no delay, making operations more straightforward. However, this also places new demands on operators — they must learn to manage energy efficiently, closely monitor power consumption, and plan vessel speed in a more rational manner.


The ship has also adopted two permanent magnet synchronous propulsion motors, capable of cutting carbon emissions by 1,462 tons per year, and completely eliminating emissions of sulfur oxides, nitrogen oxides and fine particles.
