EMERGENCE IN CONTEXT: A Treatise in Twenty-First Century Natural Philosophy by Robert C. Bishop, Michael Silberstein, and Mark Pexton. Oxford, UK: Oxford University Press, 2022. 363 pages. Hardcover; $103.65. ISBN: 9780192849786. *Reductionists dream of a day when all scientific truths can be derived from fundamental physics. Bishop, Silberstein, and Paxton show that dream is now dead, or at least it's quite ill. But what will replace it? One answer is "emergence," although that term is ambiguous. In its weak sense, it merely expresses pessimism about our ability to fully understand how microphysics produces all other phenomena. In its strong sense, it means that some entities have a kind of autonomy from physics, with their own "causal powers," including downward causation. Bishop et al. seek to replace strong and weak emergence with "contextual emergence." *Let's start with an example (sec 2.4). Rayleigh-Bénard convection occurs when a fluid is trapped between a heating plate below and a cooler one above. Convection cells emerge as warmer fluid rises toward the top and cooled fluid sinks. While molecular interactions play a part in this, sustained convection is impossible without the macroscopic plates. This behavior is not wholly determined by the fluid's constituent parts but rather by the context in which the fluid exists. *What this and scores of other examples show is that phenomena at a given scale often depend on a host of "stability conditions" at other scales--sometimes higher, sometimes lower. Contra the reductionist, the authors argue that the behavior of entities, properties, and processes at a given level is never wholly determined by events at a lower level. Macroscopic conditions (among other things) play an essential and ineliminable role. If we knew all the truths of nature, we would see that not all dependence is bottom-up. *"But the plates in your example are made of matter," says the critic, "We can reduce those to the behavior of atoms as well." A complete mathematical description without idealizations? "Well, it can be done in principle." Let's consider another example while we wait. Physicists in the Newtonian era devoted much time to the study of planetary orbits. One surprising stability condition is three-dimensional space. In four dimensions, regular orbits that resist small perturbations would be impossible (p. 29). Note that spatial dimensions are not part of the system. They are the context in which the system exists. Three dimensions are a necessary condition for stable orbits but cannot be reduced to the system's constituents even in principle. The properties of the parts do not determine the properties of the whole. This example illustrates why emergent properties are often inexplicable or unpredictable given complete knowledge of lower-level constituents: stability conditions are typically not at some lower level. While some stability conditions are causal and mechanical, like the plates in the convection examples, others are acausal, like conservation laws and least action principles. Still more are abstract properties of dimension and the geometry of mathematical spaces. Whichever the case, the authors consider those conditions to be as real or "fundamental" as anything at the level of elementary physics--something that sets this book apart from both reductionism and many other versions of emergentism. *Emergence is often associated with novelty, such as when a new and unexpected higher-level property emerges from its base. The authors believe this attention is misplaced. They focus instead on how stability conditions either open or close off areas of "possibility space." A possibility space is an abstraction in which each point represents a possible state or behavior of the system. For example, one point in the possibility space of a baseball represents its being in orbit--a possibility that will likely never be actualized. In Newtonian mechanics, the ball might also travel at the speed of light. Under special relativity, on the other hand, that part of possibility space is closed to the ball. As a result, no material object can reach that speed. The more interesting and neglected case occurs when stability conditions create access to parts of possibility space. For example, lasers do not exist in nature. Their stability conditions include the existence of a resonance cavity in which atoms can be electrically stimulated and isolated from their environment and putting those atoms in the proper state to begin the process (sec 4.9.1). When these conditions are in place, the area of possibility space representing coherent light becomes accessible. Such light has always been physically possible, but without the requisite context, it cannot become actual. *The authors make several applications to perennial questions in the philosophy of science that I do not have space to elaborate on. These include modality, dispositions/causal powers, properties, the laws of nature, causation, and determinism. Each of these has a relation to stability conditions that is often overlooked. The authors show how progress can be made on each question with less metaphysical baggage than many analytic metaphysicians assume. *Chapter 7 includes several possible objections, but one stands out. While we might need to use multiscale modeling in order to make predictions, that's because of our own epistemic limitations. Stability conditions are important, a critic might grant, but they are ultimately grounded in fundamental physics just like everything else. If we only knew enough about the system and its contexts, we would see how it's all due to the behavior of fields, particles, or whatever resides at the lowest level. *Bishop et al. reply that emergence has the evidence on its side, including an entire book with dozens of examples that cannot be reduced in the manner the critic envisions (p. 313). Nonetheless, the ontological reductionist continues to claim that while these examples have not yet been reduced to lower-level phenomena, it's just a matter of time. One wonders how long such promissory notes will be accepted. *My only concern is that contextual emergence might be too commonplace. Emergentists, especially of the strong variety, sometimes have difficulty providing convincing examples. Consciousness and quantum entanglement always make the list, but neither is fully understood. Contextual emergence, in contrast, is ubiquitous. Many examples are from biology and neuroscience, as one might expect, but most come from physics itself. Consider one more. Whether a dying star forms a white dwarf, neutron star, or black hole depends on its context, specifically how much mass the star had prior to collapse (sec 4.4). All three are therefore contextually emergent. But our hypothetical critic will surely complain that there's nothing emergent about this. The context is just mass, and mass is fundamental. Even some fellow emergentists might wonder whether calling every example that relies on necessary conditions "emergence" diminishes the significance of the term. Whatever the terminology, the book highlights a neglected aspect of what science tells us about the world. The objects and properties science studies depend on stability conditions, and those conditions are not typically found at smaller scales. Contextual emergence, therefore, stands in stark contrast to what reductionists had led us to expect. *Insofar as reductionism is incompatible with theism, this is the main takeaway for Christian academics. Science still tends to operate under a reductionist narrative that can deal with religious belief only in terms of psychological predispositions and sociological pressures. But if this narrative is false even in the physical sciences, then religious beliefs need not be restricted to such cramped corners. One might even wonder whether some of those beliefs are true. *Reviewed by Jeffrey Koperski, Professor of Philosophy, Saginaw Valley State University, University Center, MI 48710.

"verbiage very thinly sliced and plated up real nice" (Barrett 1)IntroductionMany of us share in an obsessive collecting of cookbooks and recipes. Torn or cut from newspapers and magazines, recipes sit swelling scrapbooks with bloated, unfilled desire. They’re non-hybrid seeds, peas under the mattress, an endless cycle of reproduction. Desire and narrative are folded into each other in our drive, as humans, to create meaning. But what holds us to narrative is good writing. And what can also drive desire is image—literal as well as metaphorical—the visceral pleasure of the gaze, or looking and viewing the sensually aesthetic and the work of the imagination. Creative WritingCooking, winemaking, and food and wine writing can all be considered art. For example, James Halliday (31), the eminent Australian wine critic, posed the question “Is winemaking an art?,” answering: “Most would say so” (31). Cookbooks are stories within stories, narratives that are both factual and imagined, everyday and fantastic—created by both writer and reader from where, along with its historical, cultural and publishing context, a text gets its meaning. Creative writing, in broad terms of genre, is either fiction (imagined, made-up) or creative nonfiction (true, factual). Genre comes from the human taxonomic impulse to create order from chaos through cataloguing and classification. In what might seem overwhelming infinite variety, we establish categories and within them formulas and conventions. But genres are not necessarily stable or clear-cut, and variation in a genre can contribute to its de/trans/formation (Curti 33). Creative nonfiction includes life writing (auto/biography) and food writing among other subgenres (although these subgenres can also be part of fiction). Cookbooks sit within the creative nonfiction genre. More clearly, dietary or nutrition manuals are nonfiction, technical rather than creative. Recipe writing specifically is perhaps less an art and more a technical exercise; generally it’s nonfiction, or between that and creative nonfiction. (One guide to writing recipes is Ostmann and Baker.) Creative writing is built upon approximately five, more or less, fundamentals of practice: point of view or focalisation or who narrates, structure (plot or story, and theme), characterisation, heightened or descriptive language, setting, and dialogue (not in any order of importance). (There are many handbooks on creative writing, that will take a writer through these fundamentals.) Style or voice derives from what a writer writes about (their recurring themes), and how they write about it (their vocabulary choice, particular use of imagery, rhythm, syntax etc.). Traditionally, as a reader, and writer, you are either a plot person or character person, but you can also be interested primarily in ideas or language, and in the popular or literary.Cookbooks as Creative NonfictionCookbooks often have a sense of their author’s persona or subjectivity as a character—that is, their proclivities, lives and thus ideology, and historical, social and cultural place and time. Memoir, a slice of the author–chef/cook’s autobiography, is often explicitly part of the cookbook, or implicit in the nature of the recipes, and the para-textual material which includes the book’s presentation and publishing context, and the writer’s biographical note and acknowledgements. And in relation to the latter, here's Australian wine educator Colin Corney telling us, in his biographical note, about his nascent passion for wine: “I returned home […] stony broke. So the next day I took a job as a bottleshop assistant at Moore Park Cellars […] to tide me over—I stayed three years!” (xi). In this context, character and place, in the broadest sense, are inevitably evoked. So in conjunction with this para-textual material, recipe ingredients and instructions, visual images and the book’s production values combine to become the components for authoring a fictive narrative of self, space and time—fictive, because writing inevitably, in a broad or conceptual sense, fictionalises everything, since it can only re-present through language and only from a particular point of view.The CookbooksTo talk about the art of cookbooks, I make a judgmental (from a creative-writer's point of view) case study of four cookbooks: Lyndey Milan and Colin Corney’s Balance: Matching Food and Wine, Sean Moran’s Let It Simmer (this is the first edition; the second is titled Let It Simmer: From Bush to Beach and Onto Your Plate), Kate Lamont’s Wine and Food, and Greg Duncan Powell’s Rump and a Rough Red (this is the second edition; the first was The Pig, the Olive & the Squid: Food & Wine from Humble Beginnings) I discuss reading, writing, imaging, and designing, which, together, form the nexus for interpreting these cookbooks in particular. The choice of these books was only relatively random, influenced by my desire to see how Australia, a major wine-producing country, was faring with discussion of wine and food choices; by the presence of discursive text beyond technical presentation of recipes, and of photographs and purposefully artful design; and by familiarity with names, restaurants and/or publishers. Reading Moran's cookbook is a model of good writing in its use of selective and specific detail directed towards a particular theme. The theme is further created or reinforced in the mix of narrative, language use, images and design. His writing has authenticity: a sense of an original, distinct voice.Moran’s aphoristic title could imply many things, but, in reading the cookbook, you realise it resonates with a mindfulness that ripples throughout his writing. The aphorism, with its laidback casualness (legendary Australian), is affectively in sync with the chef’s approach. Jacques Derrida said of the aphorism that it produces “an echo of really curious, indelible power” (67).Moran’s aim for his recipes is that they be about “honest, home-style cooking” and bringing “out a little bit of the professional chef in the home cook”, and they are “guidelines” available for “sparkle” and seduction from interpretation (4). The book lives out this persona and personal proclivities. Moran’s storytellings are specifically and solely highlighted in the Contents section which structures the book via broad categories (for example, "Grains" featuring "The dance of the paella" and "Heaven" featuring "A trifle coming on" for example). In comparison, Powell uses "The Lemon", for example, as well as "The Sheep". The first level of Contents in Lamont’s book is done by broad wine styles: sparkling, light white, robust white and so on, and the second level is the recipe list in each of these sections. Lamont’s "For me, matching food and wine comes down to flavour" (xiii) is not as dramatic or expressive as Powell’s "Wine: the forgotten condiment." Although food is first in Milan and Corney’s book’s subtitle, their first content is wine, then matching food with colour and specific grape, from Sauvignon Blanc to Barbera and more. Powell claims that the third of his rules (the idea of rules is playful but not comedic) for choosing the best wine per se is to combine region with grape variety. He covers a more detailed and diversified range of grape varieties than Lamont, systematically discussing them first-up. Where Lamont names wine styles, Powell points out where wine styles are best represented in Australian states and regions in a longish list (titled “13 of the best Australian grape and region combos”). Lamont only occasionally does this. Powell discusses the minor alternative white, Arneis, and major alternative reds such as Barbera and Nebbiolo (Allen 81, 85). This engaging detail engenders a committed reader. Pinot Gris, Viognier, Sangiovese, and Tempranillo are as alternative as Lamont gets. In contrast to Moran's laidbackness, Lamont emphasises professionalism: "My greatest pleasure as a chef is knowing that guests have enjoyed the entire food and wine experience […] That means I have done my job" (xiii). Her reminders of the obvious are, nevertheless, noteworthy: "Thankfully we have moved on from white wine/white meat and red wine/red meat" (xiv). She then addresses the alterations in flavour caused by "method of cooking" and "combination of ingredients", with examples. One such is poached chicken and mango crying "out for a vibrant, zesty Riesling" (xiii): but where from, I ask? Roast chicken with herbs and garlic would favour "red wine with silky tannin" and "chocolatey flavours" (xiii): again, I ask, where from? Powell claims "a different evolution" for his book "to the average cookbook" (7). In recipes that have "a wine focus", there are no "pretty […] little salads, or lavish […] cakes" but "brown" albeit tasty food that will not require ingredients from "poncy inner-city providores", be easy to cook, and go with a cheap, budget-based wine (7). While this identity-setting is empathetic for a Powell clone, and I am envious of his skill with verbiage, he doesn’t deliver dreaming or desire. Milan and Corney do their best job in an eye-catching, informative exemplar list of food and wine matches: "Red duck curry and Barossa Valley Shiraz" for example (7), and in wine "At-a-glance" tables, telling us, for example, that the best Australian regions for Chardonnay are Margaret River and the Adelaide Hills (53). WritingThe "Introduction" to Moran’s cookbook is a slice of memoir, a portrait of a chef as a young man: the coming into being of passion, skill, and professionalism. And the introduction to the introduction is most memorable, being a loving description of his frugal Australian childhood dinners: creations of his mother’s use of manufactured, canned, and bottled substitutes-for-the-real, including Gravox and Dessert Whip (1). From his travel-based international culinary education in handmade, agrarian food, he describes "a head of buffalo mozzarella stuffed with ricotta and studded with white truffles" as "sheer beauty", "ambrosial flavour" and "edible white 'terrazzo'." The consonants b, s, t, d, and r are picked up and repeated, as are the vowels e, a, and o. Notice, too, the comparison of classic Italian food to an equally classic Italian artefact. Later, in an interactive text, questions are posed: "Who could now imagine life without this peppery salad green?" (23). Moran uses the expected action verbs of peel, mince, toss, etc.: "A bucket of tiny clams needs a good tumble under the running tap" (92). But he also uses the unexpected hug, nab, snuggle, waltz, "wave of garlic" and "raining rice." Milan and Corney display a metaphoric-language play too: the bubbles of a sparkling wine matching red meat become "the little red broom […] sweep[ing] away the […] cloying richness" (114). In contrast, Lamont’s cookbook can seem flat, lacking distinctiveness. But with a title like Wine and Food, perhaps you are not expecting much more than information, plain directness. Moran delivers recipes as reproducible with ease and care. An image of a restaurant blackboard menu with the word "chook" forestalls intimidation. Good quality, basic ingredients and knowledge of their source and season carry weight. The message is that food and drink are due respect, and that cooking is neither a stressful, grandiose nor competitive activity. While both Moran and Lamont have recipes for Duck Liver Pâté—with the exception that Lamont’s is (disturbingly, for this cook) "Parfait", Moran also has Lentil Patties, a granola, and a number of breads. Lamont has Brioche (but, granted, without the yeast, seeming much easier to make). Powell’s Plateless Pork is "mud pies for grown-ups", and you are asked to cook a "vat" of sauce. This communal meal is "a great way to spread communicable diseases", but "fun." But his passionately delivered historical information mixed with the laconic attitude of a larrikin (legendary Australian again) transform him into a sage, a step up from the monastery (Powell is photographed in dress-up friar’s habit). Again, the obvious is noteworthy in Milan and Corney’s statement that Rosé "possesses qualities of both red and white wines" (116). "On a hot summery afternoon, sitting in the sun overlooking the view … what could be better?" (116). The interactive questioning also feeds in useful information: "there is a huge range of styles" for Rosé so "[g]rape variety is usually a good guide", and "increasingly we are seeing […] even […] Chambourcin" (116). Rosé is set next to a Bouillabaisse recipe, and, empathetically, Milan and Corney acknowledge that the traditional fish soup "can be intimidating" (116). Succinctly incorporated into the recipes are simple greyscale graphs of grape "Flavour Profiles" delineating the strength on the front and back palate and tongue (103).Imaging and DesigningThe cover of Moran’s cookbook in its first edition reproduces the colours of 1930–1940's beach towels, umbrellas or sunshades in matt stripes of blue, yellow, red, and green (Australian beaches traditionally have a grass verge; and, I am told (Costello), these were the colours of his restaurant Panoroma’s original upholstery). A second edition has the same back cover but a generic front cover shifting from the location of his restaurant to the food in a new subtitle: "From Bush to Beach and onto Your Plate". The front endpapers are Sydney’s iconic Bondi Beach where Panoroma restaurant is embedded on the lower wall of an old building of flats, ubiquitous in Bondi, like a halved avocado, or a small shallow elliptic cave in one of the sandstone cliff-faces. The cookbook’s back endpapers are his bush-shack country. Surfaces, cooking equipment, table linen, crockery, cutlery and glassware are not ostentatious, but simple and subdued, in the colours and textures of nature/culture: ivory, bone, ecru, and cream; and linen, wire, wood, and cardboard. The mundane, such as a colander, is highlighted: humbleness elevated, hands at work, cooking as an embodied activity. Moran is photographed throughout engaged in cooking, quietly fetching in his slim, clean-cut, short-haired, altar-boyish good-looks, dressed casually in plain bone apron, t-shirt (most often plain white), and jeans. While some recipes are traditionally constructed, with the headnote, the list of ingredients and the discursive instructions for cooking, on occasion this is done by a double-page spread of continuous prose, inviting you into the story-telling. The typeface of Simmer varies to include a hand-written lookalike. The book also has a varied layout. Notes and small images sit on selected pages, as often as not at an asymmetric angle, with faux tape, as if stuck there as an afterthought—but an excited and enthusiastic afterthought—and to signal that what is informally known is as valuable as professional knowledge/skill and the tried, tested, and formally presented.Lamont’s publishers have laid out recipe instructions on the right-hand side (traditional English-language Western reading is top down, left to right). But when the recipe requires more than one item to be cooked, there is no repeated title; the spacing and line-up are not necessarily clear; and some immediate, albeit temporary, confusion occurs. Her recipes, alongside images of classic fine dining, carry the implication of chefing rather than cooking. She is photographed as a professional, with a chef’s familiar striped apron, and if she is not wearing a chef’s jacket, tunic or shirt, her staff are. The food is beautiful to look at and imagine, but tackling it in the home kitchen becomes a secondary thought. The left-hand section divider pages are meant to signal the wines, with the appropriate colour, and repetitive pattern of circles; but I understood this belatedly, mistaking them for retro wallpaper bemusedly. On the other hand, Powell’s bog-in-don’t-wait everyday heartiness of a communal stewed dinner at a medieval inn (Peasy Lamb looks exactly like this) may be overcooked, and, without sensuousness, uninviting. Images in Lamont’s book tend toward the predictable and anonymous (broad sweep of grape-vined landscape; large groups of people with eating and drinking utensils). The Lamont family run a vineyard, and up-market restaurants, one photographed on Perth’s river dockside. But Sean's Panoroma has a specificity about it; it hasn’t lost its local flavour in the mix with the global. (Admittedly, Moran’s bush "shack", the origin of much Panoroma produce and the destination of Panoroma compost, looks architect-designed.) Powell’s book, given "rump" and "rough" in the title, stridently plays down glitz (large type size, minimum spacing, rustic surface imagery, full-page portraits of a chicken, rump, and cabbage etc). While not over-glam, the photography in Balance may at first appear unsubtle. Images fill whole pages. But their beautifully coloured and intriguing shapes—the yellow lime of a white-wine bottle base or a sparkling wine cork beneath its cage—shift them into hyperreality. White wine in a glass becomes the edge of a desert lake; an open fig, the jaws of an alien; the flesh of a lemon after squeezing, a sea anemone. The minimal number of images is a judicious choice. ConclusionReading can be immersive, but it can also hover critically at a meta level, especially if the writer foregrounds process. A conversation starts in this exchange, the reader imagining for themselves the worlds written about. Writers read as writers, to acquire a sense of what good writing is, who writing colleagues are, where writing is being published, and, comparably, to learn to judge their own writing. Writing is produced from a combination of passion and the discipline of everyday work. To be a writer in the world is to observe and remember/record, to be conscious of aiming to see the narrative potential in an array of experiences, events, and images, or, to put it another way, "to develop the habit of art" (Jolley 20). Photography makes significant whatever is photographed. The image is immobile in a literal sense but, because of its referential nature, evocative. Design, too, is about communication through aesthetics as a sensuous visual code for ideas or concepts. (There is a large amount of scholarship on the workings of image combined with text. Roland Barthes is a place to begin, particularly about photography. There are also textbooks dealing with visual literacy or culture, only one example being Shirato and Webb.) It is reasonable to think about why there is so much interest in food in this moment. Food has become folded into celebrity culture, but, naturally, obviously, food is about our security and survival, physically and emotionally. Given that our planet is under threat from global warming which is also driving climate change, and we are facing peak oil, and alternative forms of energy are still not taken seriously in a widespread manner, then food production is under threat. Food supply and production are also linked to the growing gap between poverty and wealth, and the movement of whole populations: food is about being at home. Creativity is associated with mastery of a discipline, openness to new experiences, and persistence and courage, among other things. We read, write, photograph, and design to argue and critique, to use the imagination, to shape and transform, to transmit ideas, to celebrate living and to live more fully.References Allen, Max.

Introduction 1. In an era of globalization, international trade is inevitable. When we walk into a supermarket and find South American bananas, Malaysian rubber products, Brazilian coffee, we simply experience the impact of global trade. Global trade allows all countries around the world to publicise their markets and to supply goods and services that otherwise would not have been open to the domestic economy. As all goods and services are available at relatively cheaper prices in the international market, therefore domestic market becomes more competitive. People have got choices for competitive products. Therefore, the difference in the prices of goods of the foreign economy and domestic economy results in international trade. 2. Why nations trade with each other ? Not a single nation alone can generate all the goods and services for its households in today’s world of limitless desires. There is an unequal distribution of factors of production over the countries of the world. Countries of the world differ from each other in terms of natural resources, technology, entrepreneurial and managerial skills which determine the ability of the country concerned, at the lowest cost of production, to manufacture goods and services. For example, South Korea can manufacture cars or microelectronic products effectively in comparison with any other nation in the world, similarly Malaysia could produce rubber and palm oil more efficiently. The ability to manufacture these products, such as electronics or rubber, is much greater than their ability to consume these goods within the country so that they can sell these goods at comparatively cheaper prices to other countries around the world. Similarly, India and Brazil can import certain products from South Korea and Malaysia at lower prices and can in exchange, import Brazilian coffee or Indian textiles at a lower price. Therefore, generally trade benefits all the countries of the world provided it is free trade. If one country has a belief in free trade and the other beliefs in the opposite, only the previous one will end practicing free trade and suffering in the end. Economists say that trade conflicts safeguard economic interests and are advantageous to the local market, but critics claim that they ultimately hurt local companies, consumers, and the economy in long run. Protectionist policies always harm the concept of globalization. According to the World Commission on the social dimension of globalization (2004). “Globalisation should benefit all the countries and should raise the welfare of all people throughout the world”. Advocates of protectionist view put arguments in favour of restrictions of the trade like the expansion of the home market, keeping money at home, counteracting foreign low wages, defence or national security arguments, protection of infant industry, anti-dumping arguments, and balance of payment arguments. Trade restrictions are of two types; tariff barriers and non-tariff barriers. The tariff barrier is the most common barrier to trade. It is the tax or duties that one country imposes on exported or imported goods. There are various types of tariff barriers in international trade. If the tariff is imposed based on the physical weight of some goods, imported or exported, called a specific tariff. • If a tariff is imposed on the value of some goods, imported or exported is called “Ad Valorem tariff”. • If different rates of the tariff are imposed on different countries called discriminatory tariffs. • If the same rates of a tariff are imposed on different countries, called non-discriminatory tariff’. • If the main purpose of imposing a tariff is to produce revenue, called a revenue tariff. • And the most commonly used tariff is the Protective tariff. if the tariff is imposed mainly to protect domestic industries from foreign competitions are called the protective tariff 4. Followers of the protectionist policy argue that tariff imposition has two impacts; revenue increases after the imposition of tariff and home production increases which is called protective effect but if other countries retaliate in the same manner, the trade war is inevitable. A situation of trade war erupts when one nation or economy strike back against another economy by imposing trade barriers. The application of trade restrictions is not a new concept in international trade. If we study the background of the global trade war, we find that countries frequently used trade restrictions in global trade. The situation was aggravated after the second world war. Most of the countries were intentionally devaluing their currency to increase their export and minimise imports. This was also the reason for the currency war between countries. 5. We can divide the world trade in the pre-Bretton Woods and post Bretton Woods period. An efficient international monetary system is very essential for the smooth functioning and expansion of international trade. From the early 19th century until the first world war, the era was regarded as a period of internationalism. Most of the major industrialised nations of the world started participating in world trade. After the second world war and the hectic slump and currency war that followed it all the countries of the world wished to return to normalcy. Two causes were responsible for this wish: - • Reconstruction of the economies ravaged by the war. • To end the currency war. As far as the second cause is concerned many countries or the trading partners of the world started devaluating its currency to improve the conditions of their BOP. This resulted in a trade war between nations. Therefore, in Bretton Woods, New Hampshire, USA, members of 44 countries met to discuss these problems and to find realistic solutions for them. This conference proposed the establishment of: - • The International Monetary Fund (IMF), to help member countries to meet their BOP deficit problem. • IBRD, to reconstruct and develop economies of member countries. • An International Trade Organisation (ITO), to solve the problem of international trade and proper liberalisation of it. 6. However, the proposal for the International Trade Organisation did not materialise and the General Agreement on Tariff and Trade (GATT) was formed. The GATT was established in 1948 with a big and important objective of “free trade” and “no trade war”. Its main purpose was to remove trade restrictions which sooner or later converts into a trade war. The first seven rounds of GATT were focussed on the removal of trade barriers only. Despite these discussions in several rounds of GATT, it couldn’t provide a useful forum for discussion on international trade issues. 7. The 8th round of GATT is called Uruguay Round which started in 1986. Member countries negotiated in the areas of Tariffs, Non-Tariff Measures, Tropical Production, Natural resource-based products, Agriculture, GATT articles, Safeguards, Multilateral trade negotiation agreement, Subsidies, Disputes Settlement, Trade-Related Intellectual Property Rights (TRIPPS), Trade-Related Investments measures (TRIMS), Functioning of GATT system (FOGS). Despite serious discussion on these issues’ agreement could not be reached and member countries kept on using trade and non-trade barriers on each other. 8. COVID-19 pandemic, which started in March 2020, has adversely affected global trade. As per WTO statistics, a 3% fall in the volume of merchandise (export and import) trade is seen in the first quarter of 2020. Lockdown in many economies of the world aggravated the problem and declines are historically large. Strict social distancing and majors and restrictions on travel and transport adversely affected the service sector of the world economy which is the main contributor to gross domestic product (GDP) of many countries. Therefore, the economic recovery from the COVID situation is highly uncertain. This situation might give a boost to the global trade war which will be the endeavour during the research to be found out and a description of the same has been covered in Chapter 3. The research has tried to reveal how the pandemic has crippled the world economy and aggravating the pre-existing problem of the trade war. The recent trade war between China and the USA is an apt example. Recent Examples of Trade War​​ 9. Since the year 2018 world has been witnessing trade conflict which was earlier currency conflict between the USA and its economic partners mainly the EU and China. But in this conflict US’s all-weather friend Canada and Mexico were also hit. However, retaliation by other countries has been very limited. In March 2018, the United States announced the imposition of additional tariffs under Section 232 on imports of steel (25%) and aluminium (10%) from China to the United States. This might harm the Chinese economy as China is the major contributor of crude and finished steel in the world. 10. In the same month, the US President announced his strategy to endorse restrictions against China over its Intellectual Property Rights (IPR) policies which were severely affecting its stakeholders. In this sanction, the US raised tariffs by 24 to 25% on selected Chinese products which were valued to the tune of approximately $50 billion. By adopting the policy of quid pro quo China on 01 April responded with 25% tariffs on $50 billion in US exports on various American products, like agriculture, pork, and cars. On 3rd April 2018, the US administration released a list of 1,333 goods equivalent to $50 billion in trade, which it said would enforce a 25% tariff. 11. These Chinese products mainly belong to the category of important sectors like robotics, rail and shipping, information technology, health care, and medicine, and high-technology. China retaliated and published a list of 106 products on which 25% tariffs were imposed and its value was worth $50 billion in trade. Thus, quid pro quo tactics kept ongoing between China and the US. The US plans to tax $50 billion worth of Chinese imports was replied with threats by China to impose tariffs on American products worth $50 billion. China announced to hit back with additional taxes on American chemicals, automobiles, and other products. Interestingly all these 106 American products are produced in those regions of the US where President Trump enjoys great support of his people. Earlier this year both countries signed the first phase of the trade agreement to reduce trade pressures between them, which last year weakened global growth and scaled-down business investment around the world. But due to the blame game over the pandemic, progress has been derailed. 12. Apart from the above, the subsidy has been one of the major causes of dispute amongst countries of the world. According to the WTO agreement on agriculture, developed economies had to reduce their subsidies by 21% in six years and developing countries by 12% in 10 years. Recently restriction on Indian agriculture produce by US, EU, Canada, Brazil, and Japan has been imposed in August 2020. They have questioned that India is not following the WTO peace clause for surpassing the limit on support or, subsidy it can render to its peasants. In the platform of WTO, the ceiling for subsidy is 10% of the value of the produce. India provided the WTO with details that the value of its rice production in 2018 was $43.6 billion and subsidies were worth just $5 billion. Subsidies have therefore remained a major bone of contention between the various countries of the world, but there is one peace arrangement in the WTO that protects the WTO members’ food procurement program for developing countries from taking action in the event of a violation of the subsidy cap. It will also be a litmus test to observe if in circumstances like the ongoing pandemic, WTO members grant food security pre-eminence to emerging economies or whether developed nations are pursuing market entree. Globalisation has reached a few obstructions in recent times, following decades of surges in world trade, worldwide tourism, and global cooperation, as some of the development achieved in the past has been undone by the re-emergence of patriotism and protectionism. The COVID-19 pandemic is predicted to trigger an unprecedented deterioration in global trade after trade growth decelerated dramatically in 2019, owing in huge part to trade conflict between the United States and China. As per the forecasts of the WTO, merchandise business is going to plunge between 12.98% and 31.88% this year, depending on how easily the coronavirus is controlled and trade will return to pre-crisis levels. According to the WTO Director-General, Roberto Azevêdo, the swift and robust rebound is only possible through the focus on free trade. Global markets have to be kept open and predictable, in addition to promoting a more desirable business climate. 13. Though before the onset of the pandemic, the Indian economy was not affected much by the ongoing trade conflict between the USA and China because of the combined effect of the pandemic and trade war India’s GDP shrunk by 23.9% in the first quarter of FY 2020-21. In the first quarter, the worst-hit industry was construction, which contracted by 50 percent. The hotel industry contracted by 47%, production by 39.3%, and mining by 23.3%. Agriculture, which posted a 3.4 percent rise, was the only industry that managed to survive the recession. The economy is believed to have suffered the most during the June quarter as a result of the nationwide lockdown. 14. In January 2019, as the trade war was raging, India also placed anti-dumping duties on more than 99 Chinese goods to protect its domestic markets, such as anti-dumping duties on chemicals, petrochemicals, fabrics, yarn, pharmaceutical equipment, rubber, and steel products. As a follower of protectionist policy Indian government also imposes anti-dumping duty on imports of steel products, an alloy of aluminium. The total value of duty imposed was $13.07 per ton to $ 173.1 per ton, which is a big amount. China, Vietnam, South Korea for five years in June 2020. India needs to take some major steps and reforms to bounce back its economy back on track. 15.

(j) ​International Economics by Dominick Salvatore by Wiley, January 1, 2014. ​​Dominick Salvatore, the author of international economics is an American economist. This book presents theories of international economics and its relevance through real-world examples and applications. Articles. ​ Several articles on the subject relating to the global trade, trade conflict and its effects on world have been written by many noted columnists and authors. Apart from that in last 10 months number of organisations and research bodies also carried out the analysis and likely effects of the COVID-19 pandemic on the world trade and ongoing trade conflict. Articles from publications such as ‘The Economics Times’, ‘Business Today’, ‘The Hindu’, ‘National Council of Applied Economic Research’, ‘BBC Economic Research’, ‘Economic Research and Statistics Division (ERSD)’, ‘Investopedia’ and ‘Business Insider’ form a part of the literature review for the research. In addition to the articles and journals by various writers certain data were also taken from the governmental and non-governmental reports like United Nations Conference on Trade and Development(UNCTAD), WTO Press releases and Economic Survey of India. The existing literature provides great insight into the reasons of trade between the countries, trade conflict and its catalyst and how an unforeseen event like the pandemic brings the entire world to a standstill where even largest and strongest have no solution. There are number of literature and research available which brings out many scenarios where the current trade conflict can go. Besides, a large number of research papers have also been written about the likely recovery of the world trade in various different scenarios. Study of some of has definitely given an insightful perspective on the subject. There is, however a void in the research writings on the subject from Indian government’s concerned ministry like Ministry of Finance, Ministry of Trade and Commerce and Ministry of Agriculture. The Economic Survey of India was the only document where authentic data could have been found but that too was almost six to eight months old. The updated analytical facts and data from the ministry’s sites will go a long way in helping a researcher for his work. A critical study of books and articles mentioned above has assisted in the research to address the issues identified. ​16.

Research Methodology Owing to the current and contemporary nature of the topic, research was based on the primary and secondary method of data collection wherein the number of books, open-source articles, internet blogs, periodicals, and research papers were referred and perused. Apart from the same reports and analysis of both governmental and non-governmental agencies, which were available in the open domain, were also accessed during the research. To support the arguments, an online public opinion, based on close-ended questionnaire, was be taken through Google forms. The survey questionnaire was analysed based on responses using Likert Scale. Non-random convenient sampling was used for selection of participants. A total of 114 respondents took part in the survey. 22. Organisation of the Research Research has been completed under five chapters. Headings of the chapters and their broad contents have been covered in succeeding paragraphs. (a) ​Chapter 1: Introduction and Research Methodology. In this chapter background of global trade, particularly after World War II, the role of WTO for free and fair trade amongst member nations along with research methodology have been covered in detail. (b) ​Chapter 2: Background of Global Trade War and Situation up to the onset of the COVID-19 pandemics. In this chapter issues like background of trade war, currency war and current state of global trade amidst ongoing trade conflict between the USA and China has been covered in detail. Apart from the same it has also been brought out in this chapter that which are the countries and which all products and services have been severely affected. All the affected nations are adopting their own policies to deal with the current situation of COVID-19 and ripples of trade dispute. Same have also been brought forward in this chapter. (c)​Chapter 3: Likely Directions of Global Trade War post-COVID-19 pandemics. COVID-19 pandemic has added a new dimension to the way nations were doing trade with each other, particularly in the light of disruption in production, supply chain, unpredicted market, and labour issues. Apart from that, it has severely affected the ongoing global trade war. The revival of the economy is incumbent on medical success in finding the vaccine for the disease. In this chapter likely direction of the trade war has been discussed in details. Apart from the foregoing, long and short term effects of the pandemic on global trade have also been covered in this chapter. (d) ​Chapter 4: Impact of Global Trade War and COVID-19 pandemics on the Indian Economy. The Indian economy was not affected much by the global trade war but since the onset of a pandemic, the combined effect of COVID-19 and trade war has started affecting the Indian economy. Apart from the same in this chapter impact on export and import capability of India during pandemic times have also been covered in detail. Recent development at Galwan valley in Eastern Ladakh which includes the steps taken by India and its likely implications on the trade between India and China has also been covered in this chapter. In the end an analysis of the Online survey with the help of Google form has been covered to check the hypothesis.

Apart from that actions which Indian government should take to minimise the impact of trade dispute between other nations have also been recommended. In last way ahead for the Indian economy has been recommended.

Theoretical techniques used to study time dependent electron transport in heterostructures use one or more of the following approximations: i) In Monte Carlo methods the electron is described as a point particle whose transport properties (such as effective mass, scattering rates, etc.) change abruptly when it moves across a boundary. As the electron moves across a boundary, the role of central cell symmetries (i.e., Γ, X, L character) is suppressed; ii) In time dependent quantum description, once again the electron wavepacket is assumed to abruptly see different material properties across a discontinuity. Moreover, the quantum description usually employs a one band effective mass equation that implicitly assumes that the character of the Bloch function is not significantly altered across the regions. The first approach is valid for heterostructures where electrons travel ≈ 1000 Å in each region and where the valley order is not altered across the heterostructure. The second approach is required in heterostructures of dimension ≈ 50 Å where the effects of quantum confinement are important, but where the central cell symmetry is again unchanged across the heterostructure.
