One of the most surprising elements, within the already unprecedented situation created by the COVID-19 pandemic, is the space suddenly occupied by mathematics in the world, in terms of processing public policy decisions, as well as in forms of daily communication about the disease. This essay explores ten theses about how mathematics is, and will be perceived, in a world altered by the pandemic. The different human groups facing the COVID-19 pandemic and the proliferation of messages, figures, concepts, and quantitative debates that it entails, reveals an aesthetic rather than mathematical use of the numerical. Moreover, the presence of mathematics in public debate is an indicator of the very high capacity for formal and deductive reasoning and abstraction that humanity as a whole currently possesses. However, as governments mistrusted their populations’ ability to understand, on one hand, they resolved to establish media communication about the disease in mathematical terms, and on the other, they promoted intense campaigns of fear to make people accept the unprecedented confinement due to the pandemic. Nonetheless, in the future, mathematics will increasingly become the language of politics.

Continued Employment

We draw together from Chapters 2–6 many of the factors that will push and pull activities and people to and from our cities over the next few decades. For the great World Cities, the future looks like continued employment growth overall, but reduced dependence on large floorplates and serried ranks of desks. Digitisation will bite ever deeper, and give greater flexibility to support home- and remote-workers, but the wider benefits of agglomeration and clustering will still work in favour of these cities. For other places, the challenges are even greater: ranging down from the other major conurbations to freestanding market towns, medium-sized former industrial towns, places in the hinterlands of the World Cities, and University Towns as a particular form of advanced service centre. All will need careful understanding of scale, location and interrelationships in creating effective public policy for cities and regions - with implications for developers, investors and policymakers alike.

Hailed as the “foundation of the next industrial revolution,” nanotechnology is reshaping the landscape of technological innovation and creating hope around the world. Some believe that nanotechnology can address the critical needs of developing countries, but others are less optimistic. At one end of the spectrum, scientists predict that, among other accomplishments, nanotechnology can alleviate poverty, provide safe drinking water, and cure diseases. At the other end, skeptics warn that nanotechnology can further widen the gap between the rich and the poor, contributing to an already imbalanced global landscape. What can nanotechnology bring to the 21st century? How and in what ways should it intersect with law, public policy, and the plight of the developing world?This article argues that the international community can harness nanotechnology to create sustainable development, particularly in the field of water remediation and treatment, but it must learn from its past missteps and adopt a strategy that combines two competing theories: instrumentalism and contextualism. Instrumentalism is the concept that technology is superb and stakeholders can easily transfer it from one application to another. In contrast, contextualism places technology in a socioeconomic context and conditions technological success on the stakeholders’ ability to meet local needs.

The purpose of the present study was to evaluate the contribution of various substrates to glucose synthesis in isolated sheep hepatocytes, and more specifically to quantify the contribution of propionate to gluconeogenesis. Liver cells from fed sheep have a very high capacity for propionate utilization and conversion into glucose. The glucogenicity of lactate or amino acids was very low in hepatocytes from fed sheep, but was significantly increased in hepatocytes from starved animals. Amino acids such as alanine or glutamine were characterized by a substantial utilization towards ureogenesis, whereas their conversion to glucose was very low. Propionate utilization and conversion into glucose was inhibited by butyrate, ammonia and especially ethanol (by up to 80%). Ethanol promoted a striking accumulation of intracellular malate in hepatocytes incubated with propionate (reaching 14.9 μmol/g cell) and led to a depletion of phosphoenolpyruvate; ethanol inhibition could be counteracted by pyruvate. Propionate and butyrate enhanced ureogenesis from ammonia in ruminant liver cells but their effects were not additive. Propionate also elicited a marked increase in cellular concentrations of phosphoserine and serine, particularly in the presence of ammonia; such effects could influence phospholipid metabolism in the liver. These findings emphasize the contribution of propionate, compared with the other glucogenic substrates, to glucose synthesis in ruminants and point to the possibilities of modulation of the glucogenicity of propionate by various substrates which may be present in portal blood.

According to the UN, in the next 20 years, most of the world’s population will live in urban areas. Cities consume a high amount of resources, between this water, for their sustenance, hence the greatest necessity of sustainable development plans. What viable options or strategies can we consider in Latin America such that it can resist the economic, political, and social changes that it is facing? Through prospective studies, in case of Guadalajara, it is possible to determinate how water can generate clean energy, and which are the other strategic areas to empower the city through decarbonization with an interoperative and smart loop system of co-benefits. This study can help in public policy decisions of medium-sized cities in Latin America.

Abstract Throughout the centuries, many literary authors were engaged in writing theatre plays. Although there are many studies about the theatre business in general from Medieval Times to the present, the perspective of the playwright’s profits is seldom taken into consideration. This article presents both a survey of author’s options to gain an income in the world of theatre and an analysis of the discourse about this advancement. More specifically, on the basis of a comparison of cases from the seventeenth century on the one hand and the nineteenth and twentieth centuries on the other, this article argues that, despite the fact that for playwrights, as much as for other literary authors, it was a taboo to be open about economic profits, developments in the organization of institutional theatre created temporary openings for (public debate about) financial rewards.

In 2009, the International Triathlon Union created a new triathlon race format: The World Triathlon Series (WTS), for which only athletes with a top 100 world ranking are eligible. Therefore, the purpose of this study was to analyze the influence of the three disciplines on performance within all the WTS Olympic distance races within two Olympic cycles, and to determine whether their relative contribution changed over the years. Methods: For each of a total of 44 races, final race time and position as well as split times (and positions), and summed time (and position) at each point of the race were collected and included in the analysis. Athletes were divided into 4 groups according to their final race placing (G1: 1st–3rd place; G2: 4–8th place; G3: 8–16th place and G4: ≥17th place). Two-way multivariate ANOVAs were conducted to compare the main effects of years and rank groups. For females, there were significant differences in the swim and bike segment only between G4 and the other groups (p range from 0.001–0.029), whilst for the run segment each group differed significantly from each other (p < 0.001). For males, there were significant differences in swim only between G4 and the other groups (p range from 0.001–0.039), whilst for the running segment each group differed significantly from the others (p < 0.001). Although we found running to be the segment where there were significant differences between performance groups, it is apparently important for overall success that a good runner be positioned with the first cycling pack. However, bike splits were not different between either of the four male groups or between the first 3 groups of the females. At this very high level of performance, at least in the males, the bike leg seems to be a smooth transition towards running.

Since the Chernobyl disaster, the people of the world have become concerned with environmental pollution and its effect on their health and safety. This article addresses a fundamental question arising from that concern, namely, how safe is safe enough and who should make this decision? The controversy arising from this question is between the private stakeholders and the technicians who assess risk, control information and influence public policy and both the public's perception of risk and their desire to participate directly in public policy decisions affecting their health and safety. This article proposes a solution to this controversy that is relevant to all people, since all people are stakeholders in a fair and balanced solution.

Getting students to prepare well for class is a common challenge faced by instructors all over the world. This study investigates the effects that two frequently used techniques to increase student preparation -- web postings and cold calling -- have on student outcomes. The study is based on two experiments and a qualitative study conducted in a statistics course that Masters in Public Policy (MPP) students take in their second semester at the Harvard Kennedy School. When used together, web postings and cold calling seem to increase the amount of time that students devote to reading before class by about an hour. This effect is both statistically and practically significant. However this increase in pre-class reading did not translate into increased learning (measured by average test scores on the midterm exam). Neither of the two techniques seems to be better than the other one at increasing reading time, test scores, and other student outcomes.

Thrombotic thrombocytopenic purpura (TTP) is a rare but serious illness of unknown etiology. Treatment by plasmapheresis has been reported to be effective but the mechanism for benefit is unknown. We have investigated the effect of plasmapheresis in 2 patients with TTP by quantitating platelet associated IgG (PAIgG) levels prior to and following plasmapheresis. Both patients had very high levels of PAIgG at presentation (90 and A8 fg IgG/platelet respectively, normal 0-5). in both, the PAIgG levels progressively fell to within the normal range and the platelet count rose following plasmapheresis. One patient remained in remission with normal platelet counts and PAIgG levels. The other relapsed after plasmapheresis and the PAIgG level rose prior to the fall in platelet count. Plasmapheresis was repeated and resulted in normalization of both the platelet count and PAIgG level. It is suggested that plasmapheresis removes antiplatelet antibody or immune complexes which may be of etiological importance in this illness.

The Voice

There are two most inevitable issues on national literature, in this case Indonesian literature. First is the translation and the second is the standard of world literature. Can one speak for the other as a representative? Why is this representation matter? Does translation embody the voice of the represented? Without translation Indonesian literature cannot gain its recognition in world literature, yet, translation conveys the voice of other. In the case of production, publication, or distribution of Indonesian Literature to the world, translation works can be very beneficial. The position of Indonesian literature is as a part of world literature. The concept that the Western world should be the one who represent the subaltern can be overcome as long as the subaltern performs as the active speaker. If the subaltern remains silent then it means it allows the “representation” by the Western.
