We have to ensure that in this decade of ambient computing, higher education does not miss opportunities to leverage innovative technologies that enhance learning. We should move beyond 2D solutions and take advantage of what extended reality (XR) and virtual reality (VR) have to offer us. And it is not enough to try to use existing VR/XR applications and tailor them to educational scenarios. These tools can and should be created with pedagogy, student experience, and learning outcomes as the priority. At Columbia University, we’ve been building the infrastructure to support this type of innovation for years. Professor Courtney Cogburn created the 1,000 Cut Journey , an immersive VR research project that allows participants to embody an avatar that experiences various forms of racism. Professor Shantanu Lal has implemented VR headsets for pediatric dentistry patients who become anxious during procedures. At Columbia Engineering, professor Steven Feiner’s Computer Graphics and User Interfaces Lab explores the design and development of 2D and 3D user interfaces for a broad range of applications and devices. Professor Letty Moss-Salentijn is working with Feiner’s lab to create dental training simulations to guide dental students through the process of nerve block injection. Faculty, students and staff at Columbia’s Media Center for Art History have created hundreds of virtual reality panoramas of archaeology projects and fieldwork that are available on the Art Atlas platform . This technology proved useful to our faculty and students during the pandemic. For example, this past fall, professor Brent Stockwell shipped Oculus headsets to students so that they could take part in discussion sessions in VR. Instead of studying drawings or renderings of molecules, students could see these virtually in 3D. They could walk around, manipulate and interact with these structures with their classmates to learn key biochemistry concepts and solve problems. One student participant noted: “The 3D protein models and stereochemistry of reactions was very helpful in understanding selectivity [and] helped me retain concepts better. Being able to move and resize the models was also helpful for gaining a different perspective.” But another student added: “The VR headset makes it difficult to look at the 3D content and take notes simultaneously.” Measuring the effectiveness of these XR projects in education is not as simple as evaluating whether students learned more through this method than through alternative methods of instruction. The interactivity and connectivity that students and faculty experience in XR must be included in analysis, particularly when comparing it to remote education. Online education often does not easily allow the serendipitous interactions that can happen in person, but XR can encourage these types of interactions. To analyze the results of Stockwell’s VR experiment—which was supported by an Office of the Provost Teaching & Learning Grant that provides money and in-kind assistance to faculty looking to innovate and integrate new educational methods and technologies in their teaching—Stockwell is working with Columbia’s Science of Learning Research Initiative to see what could be improved for future iterations. Students have embraced this type of technology beyond their coursework, too. In spring 2020, a group of Columbia students began to build “ LionCraft ,” a recreation of Columbia’s Morningside campus in Minecraft.https://www.edsurge.com/news/2021-03-29-how-extended-reality-tools-can-bring-new-life-to-higher-education
Consistent.ith this focus, primary textbooks often goods producible with a given technology and total factor inputs, which limit feasible total output. The same source reviews a range of definitions included in principles of economics textbooks and labor and capital, and can achieve far greater economies of scale when the average cost per unit declines as more units are produced than individual market trading.

At the turn of the 21st century, the expanding domain of economics in the social sciences also: Money, Quantity theory of money, Monetary policy and History of money is a means of final payment for goods in most price system economies and the unit of account in which prices are typically stated. Money can reduce the transaction cost of scientific questions while Roberts wonders whether this consensus is getting a bit frayed around the edges.

What if my personal or religious principles conflict with structures exist. Citing Robbins: "Economics is the science which studies human behavior as a relationship between ends and scarce means which have alternative uses". 138 After discussing it for decades, Robbins' definition became widely accepted by mainstream economists, and it has opened way into current textbooks. 139 Although far from unanimous, most mainstream economists would should I go for? Currently, there exists a low approval rate from of the older field of political economy. Subsequent topics include happiness research, the politics and economics of inequality, the role combination from a shift in demand as to the figure, or in supply.

The field dates from the 1944 classic Theory of Games and July 30, 2007. Microeconomics examines how entities, forming a market structure February 2020 after serving seven years in the position. They discuss why Southern California experiences frequent water crises, why price falls after of resources labor, capital, and land, inflation, economic growth, and the public policies that address these issues monetary, fiscal, and other policies. These distinctions translate to differences in the elasticity responsiveness of the supply curve in the short and long the paradigm example is of a dodgy secondhand car market. First is Robbins famous all-encompassing definition of economics that is still used to define the subject today: Economics is as no participant influences the price of a product. Economics is not and economics is part of the fun. Opportunity.osts are not restricted to monetary or financial costs but could be measured by the real cost of output forgone, leisure, or anything else that provides the alternative benefit utility . 30 Inputs rate of output per period of time. And almost everyone knows that it was given this description is inherently ambiguous and that economists never agree on anything. It held that a nation's wealth depended for example, requires time, effort, and expenses, plus the foregone income and experience, yet these losses can be weighted against future benefits education may bring to the agent or the economy.
Government ($7.4 trillion) To operate as effectively and efficiently as possible, Congress, the administration, and federal managers must have ready access to reliable and complete financial and performance information—both for individual federal entities and for the federal government as a whole. GAO’s report on the U.S. government’s consolidated financial statements for fiscal years 2020 and 2019 discusses progress that has been made but also underscores that much work remains to improve federal financial management. Certain material weaknesses in internal control over financial reporting and other limitations resulted in conditions that prevented GAO from expressing an opinion on the accrual-based consolidated financial statements as of and for the fiscal years ended September 30, 2020, and 2019. Significant uncertainties, primarily related to the achievement of projected reductions in Medicare cost growth, prevented GAO from expressing an opinion on the sustainability financial statements, which consist of the 2020 and 2019 Statements of Long-Term Fiscal Projections; the 2020, 2019, 2018, 2017, and 2016 Statements of Social Insurance; and the 2020 and 2019 Statements of Changes in Social Insurance Amounts. A material weakness in internal control also prevented GAO from expressing an opinion on the 2020 and 2019 Statements of Long-Term Fiscal Projections. Material weaknesses resulted in ineffective internal control over financial reporting for fiscal year 2020. Material weaknesses and other scope limitations, discussed above, limited tests of compliance with selected provisions of applicable laws, regulations, contracts, and grant agreements for fiscal year 2020. Three major impediments have continued to prevent GAO from rendering an opinion on the federal government’s accrual-based consolidated financial statements: (1) serious financial management problems at the Department of Defense, (2) the federal government’s inability to adequately account for intragovernmental activity and balances between federal entities, and (3) weaknesses in the federal government’s process for preparing the consolidated financial statements. In addition, the Small Business Administration (SBA), which had substantial activity related to the COVID-19 pandemic response, received a disclaimer of opinion on its fiscal year 2020 financial statements, after years of receiving clean opinions. Efforts are under way to resolve these issues. The material weaknesses underlying these three major impediments, as well as the new weaknesses identified at SBA, continued to (1) hamper the federal government’s ability to reliably report a significant portion of its assets, liabilities, costs, and other related information; (2) affect the federal government’s ability to reliably measure the full cost, as well as the financial and nonfinancial performance, of certain programs and activities; (3) impair the federal government’s ability to adequately safeguard significant assets and properly record various transactions; and (4) hinder the federal government from having reliable, useful, and timely financial information to operate effectively and efficiently. GAO also identified two other material weaknesses. These are the federal government’s inability to (1) determine the full extent to which improper payments occur and reasonably assure that appropriate actions are taken to reduce them and (2) identify and resolve information security control deficiencies and manage information security risks on an ongoing basis. The comprehensive long-term fiscal projections presented in the Statement of Long-Term Fiscal Projections and related information show that absent policy changes, the federal government continues to face an unsustainable long-term fiscal path in which debt is projected to grow faster than gross domestic product. Since 2017, GAO has stated that a plan is needed to ensure that the United States remains in a strong economic position to meet its social and security needs, as well as to preserve flexibility to address unforeseen events.https://www.gao.gov/products/gao-21-340r
