Eohippus Still Found in North America Free Sample for Students

Question: Discuss about the Eohippus. Answer: The Eohippus is classes of small equip ungulates but they are now extinct. Their remains were found in North America and they were approximated to have existed during the Eocene stages. Its name means a dawn horse and it is regarded as the earliest ever horse known and its size was that of a small dog (Ebach Michael, 2016). In terms of the feeding patterns, the Eohippus was an herbivore which used to graze on the shoot and soft leaves of the plants (Bokor et al., 2016). Physical characteristics In terms of its size, the Eohippus was about 60 cm long and 14 inches higher at the region near the shoulder. The front feet had four hooves while the hid leg had three hoofs. The brain was small with small lobes on the front brain. The legs were flexible and could be rotated since all the major bones were present and hence not fused together (Evans Janis, 2014). Classification Order: Perissodactyla Sub order: Hippomorpha Family: Equidae Genus: Eohippus It weighed about fifty pounds, was adapted for running and is therefore considered to be a close cousin of the horses. There has been a controversy regarding the evolution of the horses as a result of the misclassification of the eohuppus. Being an ancestor of equidae, it does not necessarily mean that it is relate to the modern day horses. Extinction The genus Equus species have lived for the last 5 million years up to the present day. With the increase in climate change, the initial climate which was warm and favorable for eohippus has now become cold i.e. the Ice Age. With increase droughts, the trees which provided the leaves as a source of food to eohippus reduced with increased grassland cover (Bell, 2014). References Bell, M. (2014).

A Guide to a Painless Undergrad Econometrics Project

A Guide to a Painless Undergrad Econometrics Project Most economics departments require second- or third-year undergraduate students to complete an econometrics project and write a paper on their findings. Many students find that choosing a  research topic  for their required  econometrics  project is just as difficult as the project itself.  Econometrics is the application of statistical and  mathematical theories  and perhaps some computer science to economic data. The example below shows how to use  Okuns law  to create an econometrics project. Okuns law refers to how the nations output- its  gross domestic product- is related to employment and unemployment. For this econometrics project guide, youll test whether Okuns law holds true in America. Note that this is just an example project- youll need to chose your own topic- but the explanation shows how you can create a painless, yet informative, project using a basic statistical test, data that you can easily obtain from the U.S. government, and a computer spreadsheet program to compile the data. Gather Background Information With your topic chosen, start by gathering background information about the theory youre testing by doing a   t-test. To do so, use the  following function:   Yt 1 - 0.4 Xt Where:Yt  is the change in the unemployment rate in percentage pointsXt  is the change in the percentage growth rate in real output, as measured by real GDP So you will be estimating the model:  Yt b1 b2 Xt Where:Yt is the change in the unemployment rate in percentage pointsXt is the change in the percentage growth rate in real output, as measured by real GDPb1 and b2 are the parameters you are trying to estimate. To estimate your parameters, you will need data. Use  quarterly economic data  compiled by the Bureau of Economic Analysis, which is part of the U.S. Department of Commerce. To use this information, save each of the files individually. If youve done everything correctly, you should see something that looks like this  fact sheet  from the BEA, containing quarterly GDP results. Once youve downloaded the data, open it in a spreadsheet program, such as Excel. Finding the Y and X Variables Now that youve got the data file open, start to look for what you need. Locate the data for your Y variable. Recall that Yt  is the change in the unemployment rate in percentage points. The change in the unemployment rate in percentage points is in the column labeled UNRATE(chg), which is column I. By looking at column A, you see that the  quarterly unemployment rate  change data runs from  April 1947 to October 2002  in cells G24-G242, according to Bureau of Labor Statistics figures. Next, find your X variables. In your model, you only have one X variable, Xt, which is the change in the percentage growth rate in real output as measured by real GDP. You see that this variable is in the column marked GDPC96(%chg), which is in Column E. This data runs from April 1947 to October 2002 in cells E20-E242. Setting Up Excel Youve identified the data you need, so you can compute the regression coefficients using Excel. Excel is missing a lot of the features of more sophisticated econometrics packages, but for doing a simple linear regression, it is a useful tool. Youre also much more likely to use Excel when you enter the real world than you are to use an econometrics package, so being proficient in Excel is a useful skill. Your Yt  data is in cells G24-G242 and your Xt  data is in cells E20-E242. When doing a linear regression, you need to have an associated X entry for every Yt  entry and vice-versa. The Xts in cells E20-E23 do not have an associated Yt  entry, so you will not use them. Instead, you will use only the Yt  data in cells G24-G242 and your Xt  data in cells E24-E242. Next, calculate your regression coefficients (your b1  and b2). Before continuing, save your work under a different filename so that  at any time, you can revert back to your original data. Once youve downloaded the data and opened Excel, you can calculate your regression coefficients. Setting Excel Up for Data Analysis To set up Excel for data analysis, go to the tools  menu on the top of the screen and find Data Analysis. If  Data Analysis  is not there, then youll have to  install it. You cannot do regression analysis in Excel without the Data Analysis ToolPak installed. Once youve selected  Data Analysis  from the  tools  menu, youll see a menu of choices such as Covariance and F-Test Two-Sample for Variances. On that menu, select Regression. Once there, youll see a form, which you need to fill in. Start by filling in the field that says Input Y Range. This is your unemployment rate data in cells G24-G242. Choose these cells by typing $G$24:$G$242 into the little white box next to  Input Y Range  or by clicking on the icon next to that white box then selecting those cells with your mouse.  The second field youll need to fill in is the Input X Range. This is the percent change in GDP data in cells E24-E242. You can choose these cells by typing $E$24:$E$242 into the little white box next to  Input X Range  or by clicking on the icon next to that white box then selecting those cells with your mouse. Lastly, you will have to name the page that will contain your regression results. Make sure you have New Worksheet Ply selected, and in the white field beside it, type in a name like Regression. Click OK. Using the Regression Results You should see a tab at the bottom of your screen called  Regression  (or whatever you named it) and some regression results. If youve gotten the intercept coefficient between 0 and 1, and the x variable coefficient between 0 and -1, youve likely done it correctly. With this data, you have all of the information you need for analysis including R Square, coefficients, and standard errors. Remember that you were attempting to estimate the intercept coefficient b1  and the X coefficient b2. The intercept coefficient b1  is located in the row named Intercept and in the column named Coefficient. Your slope coefficient b2  is located in the row named X variable 1 and in the column named Coefficient. It will likely have a value, such as BBB and the associated standard error DDD. (Your values may differ.) Jot these figures down (or print them out) as you will need them for analysis. Analyze your regression results for your term paper by doing  hypothesis testing on this sample t-test. Though this project focused on Okuns Law, you can use this same kind of methodology to create just about any econometrics project.

21st Century Learning and Teaching Assignment Example | Topics and Well Written Essays - 1000 words

21st Century Learning and Teaching - Assignment Example According to Groff (2013), the role of infusing education technology in the learning process is to create the desired school change that is responsive to the social, economic, and cultural changes affecting the learners. The researcher considers integrating this educational change in school system change through game-based learning. The main problem tackled by the author is the internationalization of education and its dependence on technology for lesson transmission. It is concluded tht barriers to lesson transmission should be used as opportunities to â€Å"engage your learners on the journey of created digital, technology-rich learning environments† (p.25). In the second article Children learning to use technologies through play: A Digital Play Framework (Bird & Edwards, 2014), gives a framework for understanding the manner in which pedagogy is conducted using game-based learning technologies. The emphasis of the research is the need to understand the use of technologies in play by children during lessons. The article looks beyond how children learn to use technologies and captures the how children play with technologies. Given the limitations in the study group, the research used a focus group approach to gather information on how children use game-based learning to explore, solve problems, acquire skills, and participate in symbolic and innovative activities. From the research findings, it is concluded that Play-based learning is an important inclusion early childhood education. Both articles acknowledge the value of game-based learning using lessons supported by technology. The value of lesson transmission forms an important part of the learning and teaching efficacy as shown in both articles. Prensky (n.d) pointed out that â€Å"play is our brain’s favorite way of learning† (p.1). With this premise, it is postulated that the importance of game-based learning is in response to the radical changes through which learners have undergone in

Housing Market in Australia Essay Example | Topics and Well Written Essays - 1500 words

Housing Market in Australia - Essay Example Bourassa (1996) has stated that the measures required for identifying the affordability of housing-ownership is primarily based upon the accumulated data but it is required to ignore the distribution of wealth and income as well as the ranges of housing prices. For analyzing the trend of housing pattern in Australia, Bourassa (1996) builds a study based upon the previous research of Grigsby and Rosenburg. The study then, proposes a method of Borrowing Constraint. The method of Borrowing Constraint was applied from the year 1989 to 1990 for household survey data for Melbourne and Sydney, Australia. The results concluded that there are hypothetical changes in interest rates and deposit requirements are kept minimum. Along with these results, furthermore, it had been concluded that under any given scenario, there is very diminutive percentage of people who are living in rented households to afford private ownership without putting themselves into the circle of poverty (Bourassa). Anothe r study conducted by Beer (1999) stated that there have been many changes in the private rental sector within the housing system of Australia. It has moved itself from the tenure of transition that is primarily comprised of saving of young household. Increase in the prices of real houses, increasing interest rates, increase in the rate of deaths of household through separation and divorces, changes in the pays of workers and inability to maintain the position of the tenure. Moreover, Beer (1999) also stated that there has been decline in access to public housing. Research conducted by Beer (1999) had emphasized on the changing dimensions of the private rental housing within Australia. The nature of investors and the size of investment in the sector of housing stocks had also been examined. Furthermore, the impact of the investment strategies on the housing sector market of Australia was also highlighted (Beer). Hayward (2008) conducted a study to determine whether the property owner s in Australia are reluctant or not. The paper covered the history of public housing and property owner in Australia. The study conducted by Hayward (2008) revealed that the golden era of public housing in Australia was from 1945 to 1956. During this time, the Commonwealth State Housing Agreement (CSHA) laid a foundation for making public housing system more viable in Australia. After that, the history of public housing started to cripple in this country. Emphasis on housing policy shifted from rentals to home ownership. Despite of viewing the development of State Housing Authorities, some people claim that this decade was not as substantial nor it was that decade where it would be favorable to return. In long run, the history of Australia is the one where the Government has been best reluctant landlords. The era from 1945 to 1956 is considered as best understood in this general trend (Hayward). The paper presented by Wulff and Maher (2010) examined the housing characteristics of pr ivate renters in Australia in long run. The study comprised of a sample of 4677 private renters. The sample had been drawn from ABS Survey of Rental Tenants 1994. The results revealed that 40% of the renters were long-term renters, having rented their property for more than 10 years, which shows that there has been substantial trend of rented household in Australia. Long-term conditions were further divided into

Electronic health record (EHR) Coursework Example | Topics and Well Written Essays - 2750 words

Electronic health record (EHR) - Coursework Example On a general scale, this type of recording system prompts direct access to key health information on the level that can be both personal and population-based. Such actions are solely executed by permitted health personnel as authorized users of the system. In whole, it is a significant provision of necessary data sets that supports the decision-making process for â€Å"quality, safety, and efficiency of patient care...(in) efficient processes for health care delivery† (Lehmann et al., 2006, p. 3). Broadly speaking, the system adapted in EHR serves as fundamental parameter in which health care team base the category of care to be provided, as past information are profound on how present health status should be approached in clinical settings. As EHR is an electronically run, it largely involves both hardware constructs and software applications. In particular, connections are managed through workstations of computer sets and servers for large database storage and application se ttings, which must be affiliated by a telecommunication services for further assistance inter-departmental network interactions within and outside the clinical zone (please see Figure 1 in Appendix A). As the hardware part of the infrastructure is presented through routers, PCs and related electronic devices, softwares are the application mechanics that run the programs needed in entering data information in computer equipments. To establish a valid link in all computer programs in different clinical departments, a â€Å"local area network (LAN)† must be installed in each computers, or â€Å"wide area networking (WAN)† in multiple site connections, uniting strategic users (billing/accounting, administrative and recording sectors) who require copies of basic and/or patient information (Walker, Bieber, & Richards, 2006). As the structural side of EHR have been explained, it is important to note that the internal flow of organization management is also a critical point in the success of the whole system. In Figure 2 (please see Appendix B) a sample of customized work flow of organization communication and function of both health care and IT teams involved in the system of electronic recording are presented. Basing from the diagram, one can surmise that the simple arrival of a clients for a check-up requires an extensive flow of functional work. In the absence of a systematized work flow structure, the whole organization may face delays as information storage and retrieval are backlogged by inappropriate system of recording. The large volume of data stored through EHR makes it an ideal system for promoting an intensive communication pattern that is both comprehensive and accurate in form. As unique identifiers, this type of system has been largely encouraged in first world countries due to its unique characteristics. It is an identification medium that can easily be accessed from internal and external data systems, efficiently discriminating between similar demographic information from potential receptors of health care (Cunningham, n.d.). The idea of storing bulk of information starting from birth to the dying moments is essential in order to trace how individuals maintain their well-being during their whole life. This is an epidemiological tool that inventively personalizes health services provided by one
