O1 Notepacket Ethanol Powered Cars While gasoline/electric hybrid cars have been on the road for awhile now, a more recent car choice facing consumers today is to drive a car based on ethanol fuels. Again, you have to do decide if it is a good option for the consumer or not based on the information we currently have on this technology. Ethanol is a wheat-based fuel additive, based on corn, barley or wheat that has been around for many years. E85 is the most popular "brand" of ethanol; it is a blend of 85 percent ethanol and 15 percent gasoline. Sam Hollen is a local farmer in Southern Wisconsin and he believes that ethanol production should be expanded. He offers the following reasons for his opinion--The benefit of this fuel is that it increases the octane in your fuel and reduces emissions. E85 also costs less for the consumer than traditional gasoline. Because the fuel is crop-based, many American farmers support ethanol and want to grow corn to fuel the country's escalating fuel needs. Ethanol is a good thing: it's domestically produced, crop-based and puts out reduced emissions. Evaline Mutos believes that Ethanol based fuel is a good thing if for one reason and that reason is to, “reduce our dependence on foreign oil”. She also mentioned that she owns a flex-fuel vehicle and so far she’s been happy with its performance. A flex fuel vehicle is one that can run on the E85 or the more traditional blend E10. This reduces the need for special fueling stations for people who own the Ethanol powered vehicles. Evaline works at the GM plant in Janesville, WI which produces many of the Flex-fuel vehicles for GM Motors. Connie Brider feels these cars are too limited yet. “We shouldn’t allow WI to jump on the bandwagon of ethanol production until the science has been proven to be effective.” She worries that we will learn that the Ethanol isn’t providing us the emissions reductions we thought and that many companies based on ethanol production will not survive if we build too many, too soon. She is an economist for the state of WI. 2 Practice Issue Investigation—Ethanol Powered Cars: Read the article and then try to complete the 5-step issue investigation process.

  • An Exploration of Human Population Demographic Data
    Tested Studies for Laboratory Teaching Proceedings of the Association for Biology Laboratory Education Vol. 32, 406–421, 2011 Behind the Numbers: An Exploration of Human Population Demographic Data Teresa C. Weglarz Department of Biological Sciences, University of Wisconsin – Fox Valley, 1478 Midway Rd, Menasha WI 54952 USA ([email protected]) Increasingly global population size has been a cause for alarm among scientists. Currently, global population size is 6.9 billion and estimates for 2050 range from 8-12 billion. It is estimated that the majority of population growth in the next 50 years will be in developing countries. This computer-based lab activity explores some of the social, economic, and political factors that influence population growth. Understanding the role of these factors in popula- tion growth is critical to the study of population demography. Population demographic data provides a glimpse into the population characteristics that are associated with rapid growth. The International Data Base provides popula- tion pyramids and demography data, on infant mortality rates, fertility rates, and life expectancy of populations in over 200 countries. This population demographic data provides a glimpse into the population characteristics that are associated with population growth and may provide clues on how to address population growth. Keywords: Population growth, demography, population pyramids Introduction Introduction Human demography is the study of population charac- tion data contains estimates and projections for more than teristics. The purpose of this computer investigation is to 200 countries, which includes population size, fertility, analyze the demographic relationships between different mortality and migration rates.

  • POPULATION PYRAMIDS LESSON Objectives Intro to Population
    Name: ____________________________________ Period: ______ POPULATION PYRAMIDS LESSON Objectives 7A Construct and analyze population pyramids and use other data, graphics, and maps to describe the population characteristics of different societies and to predict future population trends. Intro to Population Pyramids Demography is the study of human populations and how they change over time. Demographers look at birth rates and death rates and human migration. These measures help them track population trends, or the general direction in which population numbers are moving. The diagrams above are called population pyramids. They show the makeup of a country’s population by sex and age groups. Geographers use such diagrams to study population trends in a country. The shape of a population pyramid shows how a country’s population is growing. A pyramid that is wide at the bottom shows rapid population growth. More babies are being born each year than the number of people who die. A pyramid with straight sides shows slow population growth, with births and deaths nearly equal in that country. A pyramid that is narrow at the bottom shows negative population growth. More people are dying each year than are being born.

  • Pyramid Population Prediction Using Age Structure Model
    CAUCHY –Jurnal Matematika Murni dan Aplikasi Volume 6(2) (2020), Pages 66-76 p-ISSN: 2086-0382; e-ISSN: 2477-3344 Pyramid Population Prediction using Age Structure Model Heni Widayani1, Nuning Nuraini2, Anita Triska3 1,2,3Department of Mathematics, Faculty of Mathematics and Natural Sciences, Institut Teknologi Bandung Email: [email protected], [email protected], [email protected] ABSTRACT Population composition in a country by sex and age-structure often illustrated through the Population Pyramid. In this study, an age-structure model will be constructed to predict the population pyramid shape in the coming year. It is assumed that changes in population are affected by natality and mortality number in each age group, ignoring migration rates. The proposed age structure model formulated as a first-order partial differential equation with the non-negative initial condition. The boundary condition is given by the number of births which is proportional to the number of women at childbearing age. Then, this age structure model implemented utilizing United Nations Data to predict population pyramids of Indonesia, Brazil, Japan, the USA, and Russia. The population pyramid prediction of the five countries shows different characteristics, according to whether it is a developing or developed country. The results of this study indicate that the age structure model can be used to predict the composition of the population in a country in the next few years. Indonesia is predicted to be the highest populated country in 2066, compared to the other four countries. This result can be used as a reference for the government to plan policies and strategies according to age groups to control population explosion in the future.

  • Let's Put Demography Back Into Economics: Population Pyramids In
    Let’s Put Demography Back into Economics: Population Pyramids in Excel Humberto Barreto Q.G. Noblitt Professor of Economics and Management DePauw University Greencastle, IN 46135 May 11, 2016 Working Paper Please do not quote without permission. All comments welcome. Thanks to Frank Howland for early conversations and discussion, especially on Cuba, and Andrew Pinney for help on understanding estimates of Afghanistan’s population. Abstract In 1960, George Stigler wrote that, “In 1830, no general work in economics would omit a discussion of population, and in 1930, hardly any general work said anything about population.” Today, the economics curriculum remains largely devoid of demography and this needs to change immediately. After witnessing a population explosion in the last half of the 20th century, fertility rates are crashing throughout the world. We are in the midst of another demographic sea change, slamming on the brakes right after accelerating faster than ever before. This has important consequences for economies everywhere. Instead of glibly tossing a dependency ratio onto a slide, this paper offers an easy way to improve demographic literacy in undergraduate economics students using population pyramids. Hypothetical data are used to explain the pyramid and teach its dynamic properties, then real-world data are used to provide historical context, current demographic snapshots, and a glimpse of the future. Throughout, Microsoft Excel is used and its ability to download data directly from the US Census Bureau’s International Data Base with a single click of a button provides a flexible, powerful tool to explore various countries. Download PopulationPyramid.xlsm from academic.depauw.edu/~hbarreto/working and follow along with the instructions provided in this paper.
