This study examines the question of whether or not the technology of bullock traction has spread in northern Ghana between 1982/83 and 1993/94 and, furthermore, what factors determine changes in the pattern of the adoption of bullock traction in this area. The introduction to the problem and the objectives of the study in chapter one are followed by a theoretical section in chapter two that focuses on the question why one would have expected a further spread of bullock traction. This chapter explains the direct benefits of bullock traction and reviews the current state of knowledge of this issue. Factors that might have resulted in changes in these direct benefits of bullock traction between 1982/83 and 1993/94 such as population growth and the effects of structural adjustment programs are discussed. Additionally, the implications of the life-cycle of households and the tradition of the inheritance of cattle for changes related to bullock traction adoption over time are identified. Chapter three introduces the empirical data collection procedure and methods. The study is a follow up study to the study of Panin (1988) who conducted research on the same farm-households in 1982/83, in three villages of the Northern Region of Ghana. Chapter four presents the empirical findings about the changes in the socio-economic conditions that are relevant for bullock traction adoption in the study villages. These data extend the information in chapter two to the village level. The empirical findings about changes in the effects of bullock traction at the field level are presented in chapter five. The analysis includes the effects of bullock traction on land use, household labor utilization, performance of crop production, and aspects of bullock traction renting. The effects of bullock traction at the farm-household level were addressed in chapter six. It is necessary to separate the analysis at the field level from the farm-household level analysis because farmers combine different tillage technologies at the farm-household level. This chapter includes changes over time regarding household demographics, resource endowment, farm labor allocation, crop production performance, income statements, and the costs and benefits of an investment in bullock traction. Chapter seven of this study is concerned with the question of whether the changes in the bullock ownership pattern for the sampled households are in line with general trends at village level. For this purpose, the village census of 1994 was compared with 1982 and the result is that the ownership of bullocks and implements has declined which means that the results of the analysis at farm-household level is in line with general trends at village level. Although individual ownership of bullock traction declined, the area plowed by bullocks in the study area increased because renting of bullock traction services increased. Chapter eight of the study discusses important empirical results of chapters four to seven in light of the arguments made in the theoretical chapter two and draws attention to the conclusions of the empirical results. Important points discussed in chapter eight are: methodological issues, the labor-saving effect of bullock traction that is maintained over the years, the effect on crop yields that was found to exist in 1982 but not in 1994, the importance of the life-cycle of households to understand changes in bullock traction adoption at farm-household level, and the effects of structural adjustment programs on the adoption of bullock traction. The study ends with the formulation of recommendations for agricultural extension and further agricultural research. About the Author

Developed in the late 1850s, the traction engine revolutionized the agriculture industry. James H. Maggard, an authority on steam power, wrote The Traction Engine for the ¿rough and tumble engineers¿ tasked with operating these machines in the field. That was not an altogether easy task, even for a seasoned professional. Breakdowns, boiler explosions, and injury could result, if one was inattentive. This reprint of the 1900 edition of the book features expanded chapters on the subject of threshing machines and the new internal combustion engine models.

Most startups don’t fail because they can’t build a product. Most startups fail because they can’t get traction. Startup advice tends to be a lot of platitudes repackaged with new buzzwords, but Traction is something else entirely. As Gabriel Weinberg and Justin Mares learned from their own experiences, building a successful company is hard. For every startup that grows to the point where it can go public or be profitably acquired, hundreds of others sputter and die. Smart entrepreneurs know that the key to success isn’t the originality of your offering, the brilliance of your team, or how much money you raise. It’s how consistently you can grow and acquire new customers (or, for a free service, users). That’s called traction, and it makes everything else easier—fund-raising, hiring, press, partnerships, acquisitions. Talk is cheap, but traction is hard evidence that you’re on the right path. Traction will teach you the nineteen channels you can use to build a customer base, and how to pick the right ones for your business. It draws on inter-views with more than forty successful founders, including Jimmy Wales (Wikipedia), Alexis Ohanian (reddit), Paul English (Kayak), and Dharmesh Shah (HubSpot). You’ll learn, for example, how to: ·Find and use offline ads and other channels your competitors probably aren’t using ·Get targeted media coverage that will help you reach more customers ·Boost the effectiveness of your email marketing campaigns by automating staggered sets of prompts and updates ·Improve your search engine rankings and advertising through online tools and research Weinberg and Mares know that there’s no one-size-fits-all solution; every startup faces unique challenges and will benefit from a blend of these nineteen traction channels. They offer a three-step framework (called Bullseye) to figure out which ones will work best for your business. But no matter how you apply them, the lessons and examples in Traction will help you create and sustain the growth your business desperately needs.

Most startups end in failure. Almost every failed startup has a product. What failed startups don't have are enough customers. Traction Book changes that. We provide startup founders and employees with the framework successful companies use to get traction. It helps you determine which marketing channel will be your key to growth. "If you can get even a single distribution channel to work, you have a great business." -- Peter Thiel, billionare PayPal founder The number one traction mistake founders and employees make is not dedicating as much time to traction as they do to developing a product. This shortsighted approach has startups trying random tactics -- some ads, a blog post or two -- in an unstructured way that will likely fail. We developed our traction framework called Bullseye with the help of the founders behind several of the biggest companies and organizations in the world like Jimmy Wales (Wikipedia), Alexis Ohanian (Reddit), Paul English (Kayak.com), Alex Pachikov (Evernote) and more. We interviewed over forty successful founders and researched countless more traction stories -- pulling out the repeatable tactics and strategies they used to get traction. "Many entrepreneurs who build great products simply don't have a good distribution strategy." -- Mark Andreessen, venture capitalist Traction will show you how some of the biggest internet companies have grown, and give you the same tools and framework to get traction.

The Terre Haute, Indianapolis & Eastern Traction Company was the ultimate survivor of the more than forty smaller companies which organized, struggled to exist, and finally became a part of the actual operating system popularly known as THIE. From its conception in 1907 as the lessee of several existing larger companies, the THIE system became a worthy competitor for the state's other large interurban company, the Union Traction Company of Indiana. While the mileages operated by the two concerns were roughly equal, and continually changing, THIE did outperform UTC in several categories, such as stock hauling and safety (the THIE safety record far out performed UTC's, both if frequency of accidents and number of fatalities). The history records THIE, s growth from a tiny city installation in Brazil to a multi-county system serving areas of large population such as Indianapolis down to tiny Amo and Dunreith. Covered too are city lines in Crawfordsville (and its pitched battle to originally build!) New Castle, Richmond, and Terre Haute, along with the connecting Lebanon and Thorntown Traction as well as a line which started but petered out five miles out of town - the Covington and Southwestern Traction Company. Other subjects covered are the THIE passenger and freight service, despatching practices, stations and terminals, rolling stock rosters, mileage tables, and other necessary ancillary data to round out the line's history.
