Abstract
This study examines forecast accuracy associated with the forecast of 55 revenue data series of 18 local governments. The last 18 months (6 quarters; or 2 years) of the data are held-out for accuracy evaluation. Results show that forecast software, damped trend methods, and simple exponential smoothing methods perform best with monthly and quarterly data; and use of monthly or quarterly data is marginally better than annualized data. For monthly data, there is no advantage to converting dollar values to real dollars before forecasting and reconverting using a forecasted index. With annual data, naïve methods can outperform exponential smoothing methods for some types of data; and real dollar conversion generally outperforms nominal dollars. The study suggests benchmark forecast errors and recommends a process for selecting a forecast method.

Abstract
Purpose – Driver education and licensing are two mechanisms used to reduce crash rates. The purpose of this chapter is to provide an overview of these countermeasures and consider how simulators can be used to augment more traditional approaches.
Approach – A literature review was undertaken evaluating key concepts in driver licensing including graduated driver licensing (GDL), the role of parents in licensing, compliance and enforcement, driver testing and how the driver licensing system impacts on levels of unlicensed driving. Literature regarding driver education for individuals who have and not yet obtained a licence was also reviewed.
Findings – GDL is a successful countermeasure for reducing the crash rates of young novice drivers as it limits their exposure to higher risk situations. The support for driver education initiatives is mixed. As there are big differences between education programs, there is a need to consider each program on its own merits. Driving simulators provide a safe environment for novices to gain experience. In particular, they may be bifacial for development of hazard perception and visual scanning skills.
Practical Implications – GDL systems should be introduced where appropriate. Existing systems should be strengthened where possible by including additional, best-practice and restrictions. When considering driver education as a countermeasure, the type of program is very important. Education programs that have been shown to increase crashes should not be introduced. Further research and development are necessary to ensure that driver education and licensing adequately equip novice drivers with the skills necessary to drive in the 21st century.

Abstract
Chocolate and cocoa are made from the “beans” or seeds of several small trees, natives of tropical America, of which Theobroma cacao (L.) is by far the most important. Cocoa beans were highly esteemed by the aborigines, especially the Aztecs of Mexico and Peru, who prepared from them beverages and foods. They were brought to the notice of Europeans by Cortez and other explorers, but were not extensively imported into Europe until the seventeenth century, about the time tea and coffee were introduced from the East. At present the world's supply comes chiefly from Venezuela, Guiana, Ecuador, Brazil, Trinidad, Cuba, Mexico, and other regions bordering on the Gulf of Mexico, being gathered in these regions from trees both wild and cultivated; and also to some extent from Java, Ceylon, Africa, and other parts of the Old World, where the tree has been successfully cultivated.

Abstract
Middle level teachers, at times, link historical content with relevant English literature in interdisciplinary units. Elementary teachers periodically employ history-themed literature during reading time. Interconnections between language arts and history are formed with developmentally appropriate literature for students. Historical misrepresentations, however, proliferate in children’s literature and are concealed behind engaging narratives. Since literacy and historical thinking are essential skills, children’s literature should be balanced within, not banished from, the classroom. Using America’s peculiar institution of slavery as a reference point, this article examines children’s literature, identifies almost a dozen areas of historical misrepresentation, and proffers rich primary source material to balance the various misrepresentations. We provide teachers with reason for caution when including such literature; but also model how to locate, use, and, at times, abridge primary source material within an elementary or middle level classroom. Such curricular supplements provide balance to engaging but historically-blemished children’s literature and enable educators to attain the rigorous prescriptions of Common Core.
