Global commerce 

    Driverless vehicles whizz across five new berths at Tuas Mega Port, which sits on a swathe of largely reclaimed land at the western tip of Singapore. Unmanned cranes loom overhead, circled by camera-fitted drones. The berths are the first of 21 due by 2027. When it is completed in 2040, the complex will be the largest container port on Earth, boasts PSA International, its Singaporean owner.
   Tuas is a vision of the future on two fronts. It illustrates how port operators the world over are deploying clever technologies to meet the demand for their services in the face of obstacles to the development of new facilities, from lack of space to environmental concerns. More fundamentally, the city-state’s investment, with construction costs estimated at $15bn, is part of a wave of huge bets by the broader logistics industry on the rising importance of Asia, and South-East Asia in particular. The IMF expects the region’s five largest economies—Indonesia, Malaysia, Singapore, the Philippines and Thailand—to be the fastest-growing bloc in the world by trade volumes between 2022 and 2027. The result is that the map of global commerce and the blueprints for its critical nodes are being simultaneously redrawn.

Trust and audit


    Trust is what auditors sell. They review the accuracy, adequacy or propriety of other people’s work. Financial statement audits are prepared for the owners of a company and presented publically to provide assurance to the market and the wider public. Public service audits are presented to governing bodies and, in some cases, directly to parliament.

      It is the independent scepticism of the auditor that allows shareholders and the public to be confident that they are being given a true and fair account of the organisation in question. The auditor’s signature pledges his or her reputational capital so that the audited body’s public statements can be trusted. […]

    Given the fundamental importance of trust, should auditors not then feel immensely valuable in the context of declining trust? Not so. Among our interviewees, a consensus emerged that the audit profession is under-producing trust at a critical time. One aspect of the problem is the quietness of audit: it is a profession that literally goes about its work behind the scenes. The face and processes of the auditor are rarely seen in the organisations they scrutinise, and relatively rarely in the outside world. Yet, if we listen to the mounting evidence of the importance of social capital, we know that frequent and reliable contacts between groups are important to strengthening and expanding trust.

     So what can be done? Our research suggests that more frequent dialogue with audit committees and a more ambitious outward facing role for the sector’s leadership would be welcome. But we think more is needed. Audit for the 21st century should be understood and designed as primarily a confidence building process within the audited organisation and across its stakeholders. If the audit is a way of ensuring the client’s accountability, much more needs to be done to make the audit itself exemplary in its openness and inclusiveness.

    Instead of an audit report being a trust-producing product, the audit process could become a trust-producing practice in which the auditor uses his or her position as a trusted intermediary to broker rigorous learning across all dimensions of the organisation and its stakeholders. The views of investors, staff, suppliers and customers could routinely be considered, as could questions from the general public; online technologies offer numerous opportunities to inform, involve and invite.

    From being a service that consists almost exclusively of external investigation by a warranted professional, auditing needs to become more co-productive, with the auditor’s role expanding to include that of an expert convenor who is willing to share the tools of enquiry. Audit could move from ‘black box’ to ‘glass box’.

    But the profession will still struggle to secure trust unless it can stake a stronger claim to supporting improvement. Does it increase the economic, social or environmental value of the organisations it reviews? It is one thing to believe in the accuracy of a financial statement audit, but it is another thing to believe in its utility.

Adding ethics to public finance

    

    Evolutionary moral psychologists point the way to garnering broader support for fiscal policies

    Policy decisions on taxation and public expenditures intrinsically reflect moral choices. How much of your hard-earned money is it fair for the state to collect through taxes? Should the rich pay more? Should the state provide basic public services such as education and health care for free to all citizens? And so on.

    Economists and public finance practitioners have traditionally focused on economic efficiency. When considering distributional issues, they have generally steered clear of moral considerations, perhaps fearing these could be seen as subjective. However, recent work by evolutionary moral psychologists suggests that policies can be better designed and muster broader support if policymakers consider the full range of moral perspectives on public finance. A few pioneering empirical applications of this approach in the field of economics have shown promise.

    For the most part, economists have customarily analyzed redistribution in a way that requires users to provide their own preferences with regard to inequality: Tell economists how much you care about inequality, and they can tell you how much redistribution is appropriate through the tax and benefit system. People (or families or households) have usually been considered as individuals, and the only relevant characteristics for these exercises have been their incomes, wealth, or spending potential.

    There are two — understandable but not fully satisfactory — reasons for this approach. First, economists often wish to be viewed as objective social scientists. Second, most public finance scholars have been educated in a tradition steeped in values of societies that are WEIRD (Western, Educated, Industrialized, Rich, and Democratic). In this context, individuals are at the center of the analysis, and morality is fundamentally about the golden rule — treat other people the way that you would want them to treat you, regardless of who those people are. These are crucial but ultimately insufficient perspectives on how humans make moral choices.

    Evolutionary moral psychologists during the past couple of decades have shown that, faced with a moral dilemma, humans decide quickly what seems right or wrong based on instinct and later justify their decision through more deliberate reasoning. Based on evidence presented by these researchers, our instincts in the moral domain evolved as a way of fostering cooperation within a group, to help ensure survival. This modern perspective harks back to two moral philosophers of the Scottish Enlightenment — David Hume and Adam Smith — who noted that sentiments are integral to people’s views on right and wrong. But most later philosophers in the Western tradition sought to base morality on reason alone.

    Moral psychologists have recently shown that many people draw on moral perspectives that go well beyond the golden rule. Community, authority, divinity, purity, loyalty, and sanctity are important considerations not only in many non-Western countries, but also among politically influential segments of the population in advanced economies, as emphasized by proponents of moral foundations theory.

    Regardless of whether one agrees with those broader moral perspectives, familiarity with them makes it easier to understand the underlying motivations for various groups’ positions in debates on public policies. Such understanding may help in the design of policies that can muster support from a wide range of groups with differing moral values.

Language Assessment and the new Literacy Studies

Some Final Remarks


    Planning language assessment from a structuralist view of language has been a fairly easy task, since it aims at testing the correct use of grammar and lexical structures. This has been a very comfortable way to evaluate students’ performance in many regular schools or language institutes due to the stability of standardized answers. From the perspective of the new literacy studies, the comfort of teaching and assessing objective and homogeneous linguistic contents is replaced by a wider spectrum of language teaching and assessing possibilities, whose key elements turn to be difference and critique. Typical activities based on this new approach would enable students to make and negotiate meanings in a much more flexible way, corroborating the novel notion of unstable, dynamic, collaborative and distributed knowledge.

    The inclusion of contents of such nature in language assessments may be, at a first glance, a very laborious process due to the fact we are simply not accustomed to that. Actually, we sometimes find ourselves deprived from the teaching skills necessary to apply a more critical teaching approach, a fact that is much the results of our positivist educational background.

    Nonetheless, since the emergent digital epistemology will require subject more capable of designing and redesigning meaning critically towards a great deal of representational modes, we need to reconsider our teaching approaches, go further and seek theories that take such issues into account. By redefining the notions of language and knowledge, we, thus, assume that the new literacy studies from the last decades may offer very good insights to the field of foreign language teaching.

    The re-conceptualization of language assessment according to the new literacies project presented in this paper does not intend to suggest prompt fixed answers, but it takes the risk of outlining possible activities, signaling certain changes regarding its characteristics and contents, as previously shared.

    The increasing importance of the new literacy and multiliteracies studies and their fruitful theoretical insight for the rethinking of pedagogical issues invite us to review our foreign language teaching practices in a different perspective. By sharing some of our local findings, we attempt to corroborate the collaborative and distributed knowledge discussed by the literacies theory itself and hope to be contributing to the new educational demands of the emerging epistemological basis.

Nurturing Multimodalism


    […]

   New learning collaborations call on the teacher as learner, and the learner as teacher. The teacher is a lifelong learner; this is simply more apparent in the Information Age. In instances of best practice, collaborative learning partnerships are forged between and among teachers for strategic, bottom-up, in-house professional development. This allows teachers to share in reflective, on-going, contextualized learning, tailored to their collective knowledge. This sharing also includes the learner as teacher. ELT typically employs learner-centered activities: these can include learners sharing their knowledge of strategic digital literacies with others in the classrooms.

   The digital universe, so threatening to adult notions of socially sanctioned literacies, is intuitive to children, who have been socialized into it, and for whom digital literacies are exploratory play. Adults may find new ways of communicating digitally to be quite baffling and confronting of our communicative expertise; children do not. Instant messaging systems, such as MSN, AOL, ICQ, for example, provide as natural a medium for communicating to them as telephones did for the baby-boomer generation. It is not fair for the teacher to treat Information and Communication Technologies as auxiliary communication with learners for whom it is mainstream and primary.

    Learning spaces are important. Although teachers seldom have much individual say in the layout of teaching spaces, collaborative relationships may help to encourage integrated digitization, where computers are not segregated in laboratories but are interspersed throughout the school environment. In digitally infused curricula, postmodern literacies do not supplant but complement modern literacies, so that access to information is driven by purpose and content rather than by the media available.

WEIGH HEY I'm a dietitian - here's 4 physical signs you need to eat MORE carbs


(1º§) Many trendy weight loss diets encourage cutting out carbs, claiming it's the secret to dropping pounds. Both the keto and Atkins diet say to instead focus ___ eating protein and fats.


(2º§) As the body has less carbs to use for energy, it burns body fat instead. But a dietician would say this is the wrong way to approach healthy eating, and potentially dangerous.


(3º§) The body turns to stored fat when there is a lack of carbohydrate, but it also eats away at protein tissue such as in the heart or muscle, The Britician Association of UK Dieticians says.


(4º§) Each food group - carbs, proteins and fats - is important for physical health. Carbs provide fibre to keep bowels moving and prevent disease. They fuel the brain and body. Without carbs, you may get a headache, constipation, bad breath or nausea. Starchy foods, the main source of carbs, should make up a third ___ your daily diet, the NHS says.


(5º§) The BDA says: "We get energy from carbohydrates, protein, fat and alcohol in our diet. "Any extra (unneeded) energy we take in will be converted to fat no matter what the source. "Sometimes people think starchy foods are fattening however, the same amount (in weight) of carbohydrate contains less than half the calories of fat. "Studies have also shown carbohydrates are better at satisfying our hunger."


(6º§) Nichola Ludlam-Raine, a registered dietitian, told Insider there is "no good reason to remove carbs from your diet". She said: "Low-carb diets have been popular for a number of years, even decades now, but reducing your carbohydrate intake can come with a cost."


(7º§) Here are four signs you need to up your carb intake: Carbs are the body's main source of fuel, so if you reduce your carb intake significantly, you'll likely notice a depletion of your energy levels, too, Ludlam-Raine said. "Our body can use other sources of fuel (such as fat), although carbohydrates are able to provide a more rapid source of energy to enable us to function optimally, both cognitively and physically," she said.


(8º§) The primary source of energy in the brain is glucose, which comes from eating delicious carbs. It can rely on other stores, such as ketones. On the keto diet, the body turns fat into ketones in the liver, which can supply the brain. But this isn't a sustainable source of brain power, said Ludlam-Raine. Symptoms of brain fog can include moodiness, irritability and difficulty concentrating.


(9º§) Ludlam-Raine said: "Consuming carbs alongside protein helps to support the production of tryptophan, which is then converted into serotonin, also known as the happy hormone." Ludlam-Raine said the body stores carbohydrates as glycogen ___ the liver and muscles. Glycogen is the main source of energy when you do exercise, and when it's depleted, you feel fatigued. It's no wonder that on a low carb diet, you can feel too tired to go to the gym - which isn't beneficial for overall health.


(10º§) Mikle Molloy, a sports-nutrition coach, said in a worst case scenario of "exercise flu" you'll feel out of it, with a headache and muscle aches, and just want to lie on the ground. Carbs aren't just needed pre-workout, but post-workout too.


(11º§) Once the glycogen stores hit rock bottom, they need replenishing, Ludlam-Raine said. "It's recommended to consume carbohydrates alongside protein to support recovery and enable you to feel at your best before your next workout," she said.


(12º§) Feeling achy, sluggish or low in energy when you go to the gym may signal poor recovery. Some carbs are healthier options than others. Potato is best when baked, mashed or boiled as opposed to fried.


(13º§) We all know brown bread is better for us than white - but do you know why? Wholegrain, wholemeal and brown breads are more fibrous and contain B vitamins, vitamin E, fibre and a wide range of minerals.


(14º§) The same goes for pasta - try and eat wholewheat or whole grain options. Grains, such as couscous, oatmeal, brown rice and barley, are also important sources of starchy carbohydrates. Fruit and vegetables also contain carbohydrates. Ludlam-Raine recommended getting your carbs mostly from whole grains (such as brown bread and pasta), fruits, and vegetables.



https://www.thesun.co.uk/health/news-health/19109904/physical-signs-you-needeat-more-carbs/

Consider the following assertives: 


I.The word "oatmeal" could be translated as "aveia" (14º§).

II.The word "once" is a preposition (11º§).

III.The word "replenishing" could be replaced by "outshine" (11º§).


Which one(s) is(are) CORRECT?

(1º§)Volcanoes can impact climate change. During major explosive eruptions huge amounts__volcanic gas, aerosol droplets, and ash are injected into the stratosphere. Injected ash falls rapidly from the stratosphere -- most of it is removed within several days to weeks -- and has little impact on climate change. But volcanic gases like sulfur dioxide can cause global cooling, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming.


(2º§)The most significant climate impacts from volcanic injections into the stratosphere come from the conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. The aerosols increase the reflection of radiation from the Sun back into space, cooling the Earth's lower atmosphere or troposphere.


(3º§)Several eruptions during the past century have caused a decline in the average temperature at the Earth's surface of up to half a degree (Fahrenheit scale) for periods of one to three years. The climactic eruption of Mount Pinatubo on June 15, 1991, was one of the largest eruptions of the twentieth century and injected a 20-million ton (metric scale) sulfur dioxide cloud into the stratosphere at an altitude of more than 20 miles. The Pinatubo cloud was the largest sulfur dioxide cloud ever observed in the stratosphere since the beginning of such observations by satellites in 1978. It caused what is believed to be the largest aerosol disturbance of the stratosphere in the twentieth century, though probably smaller than the disturbances from eruptions of Krakatau in 1883 and Tambora in 1815. Consequently, it was a standout in its climate impact and cooled the Earth's surface for three years following the eruption, by as much as 1.3 degrees F at the height of the impact.


(4º§)The large 1783-1784 Laki fissure eruption in Iceland released a staggering amount more sulfur dioxide than Pinatubo (approximately 120-million ton vs. 20). Although the two eruptions were significantly different__length and style, the added atmospheric SO2 caused regional cooling of Europe and North America by similar amounts for similar periods of time.


(5º§)Carbon dioxide (CO2) is a greenhouse gas and is the primary gas blamed for climate change. While sulfur dioxide released in contemporary volcanic eruptions has occasionally caused detectable global cooling of the lower atmosphere, the carbon dioxide released in contemporary volcanic eruptions has never caused detectable global warming of the atmosphere. In 2010, human activities were responsible for a projected 35 billion metric tons (gigatons) of CO2 emissions. All studies to date of global volcanic carbon dioxide emissions indicate that present-day subaerial and submarine volcanoes release less than a percent of the carbon dioxide released currently by human activities. While it has been proposed that intense volcanic release of carbon dioxide in the deep geologic past did cause global warming, and possibly some mass extinctions, this is a topic of scientific debate at present.


(6º§)Published scientific estimates of the global CO2 emission rate for all degassing subaerial (on land) and submarine volcanoes lie in a range from 0.13 gigaton to 0.44 gigaton per year. The 35-gigaton projected anthropogenic CO2 emission for 2010 is about 80 to 270 times larger than the respective maximum and minimum annual global volcanic CO2 emission estimates.


(7º§)There is no question that very large volcanic eruptions can inject significant amounts of carbon dioxide into the atmosphere. The 1980 eruption of Mount St. Helens vented approximately 10 million tons of CO2 into the atmosphere in only 9 hours. However, it currently takes humanity only 2.5 hours to put out the same amount. While large explosive eruptions like this are rare and only occur globally every 10 years or so, humanity's emissions are ceaseless and increasing every year.


(8º§)There continues to be efforts to reduce uncertainties and improve estimates of present-day global volcanic CO2 emissions, but there is little doubt among volcanic gas scientists that the anthropogenic CO2 emissions dwarf global volcanic CO2 emissions.
