TL;DR: The authors provided an account of how Fermat's solution was lost, the consequent struggle by mathematicians to solve this scientific mystery and how the solution was finally found in the 1990s.
Abstract: Around 1637, the French mathematician Pierre de Fermat wrote that he had found a way to prove a seemingly simple statement: while many square numbers can be broken down into the sum of two other squares - for example, 25 (five squared) equals nine (three squared) plus 16 (four squared) - the same can never be done for cubes or any higher powers. This book provides an account of how Fermat's solution was lost, the consequent struggle by mathematicians to solve this scientific mystery and how the solution was finally found in the 1990s.

TL;DR: The story of the compass is shrouded in mystery but has its roots in ancient China around 2,000 years ago, and it was the seafarers of the Amalfi Coast who first realised its full potential some twelve centuries later as discussed by the authors.
Abstract: The story of the compass is shrouded in mystery but has its roots in ancient China around 2,000 years ago...A puzzling lodestone whose powers affected metal was know to the Chinese Emperor. Affected metal, suspended in water, always pointed north and was put to excellent use in the art of feng shui. However, it was the seafarers of the Amalfi Coast who first realised its full potential some twelve centuries later. It may have taken 1,200 years for the 'compass' to migrate to Medieval Italy, but it didn't take long for those mariners to kick-start the Age of Discovery. The compass made it all possible, and this is its fascinating story.

TL;DR: The findings of the study indicate that perceived usefulness and information on online banking on the Web site were the main factors influencing online‐banking acceptance.
Abstract: Advances in electronic banking technology have created novel ways of handling daily banking affairs, especially via the online banking channel. The acceptance of online banking services has been rapid in many parts of the world, and in the leading e‐banking countries the number of e‐banking contracts has exceeded 50 percent. Investigates online banking acceptance in the light of the traditional technology acceptance model (TAM), which is leveraged into the online environment. On the basis of a focus group interview with banking professionals, TAM literature and e‐banking studies, we develop a model indicating online‐banking acceptance among private banking customers in Finland. The model was tested with a survey sample (n=268). The findings of the study indicate that perceived usefulness and information on online banking on the Web site were the main factors influencing online‐banking acceptance.

TL;DR: The methodology to accomplish those goals and objectives will be examined and the reader will become familiar with the specific techniques used in the current study, and supported by the literature that was reviewed in the previous article.
Abstract: In the preceding article (Tellis, 1997), the goals and objectives were presented and explained in detail. In this article, the methodology to accomplish those goals and objectives will be examined. The reader will become familiar with the specific techniques that are used in the current study, and supported by the literature that was reviewed in the previous article. That methodology will follow the recommendation of Yin (1994) and has four stages: Design the case study, Conduct the case study, Analyze the case study evidence, and Develop the conclusions, recommendations and implications. The article begins with an introduction, that includes some of the background information that is intended to inform the reader. Following that section, each step of the methodology will be explored in detail. Finally a summary will connect all the information in a concise manner. This article is available in The Qualitative Report: http://nsuworks.nova.edu/tqr/vol3/iss3/1 Application of a Case Study Methodology

TL;DR: A review of the literature suggests that the evidence for the incumbent's curse is based on anecdotes and scattered case studies of highly specialized innovations as mentioned in this paper, which is not clear if it applies widely across several product categories.
Abstract: A common perception in the field of innovation is that large, incumbent firms rarely introduce radical product innovations. Such firms tend to solidify their market positions with relatively incremental innovations. They may even turn away entrepreneurs who come up with radical innovations, though they themselves had such entrepreneurial roots. As a result, radical innovations tend to come from small firms, the outsiders. This thesis, which we term the incumbent's curse, is commonly accepted in academic and popular accounts of radical innovation. This topic is important, because radical product innovation is an engine of economic growth that has created entire industries and brought down giants while catapulting small firms to market leadership. Yet a review of the literature suggests that the evidence for the incumbent's curse is based on anecdotes and scattered case studies of highly specialized innovations. It is not clear if it applies widely across several product categories. The authors reexamine the incumbent's curse using a historical analysis of a relatively large number of radical innovations in the consumer durables and office products categories. In particular, the authors seek to answer the following questions: (1) How prevalent is this phenomenon? What percentage of radical innovations do incumbents versus nonincumbents introduce? What percentage of radical innovations do small firms versus large firms introduce? (2) Is the phenomenon a curse that invariably afflicts large incumbents in current industries? Is it driven by incumbency or size? and (3) How consistent is the phenomenon? Has the increasing size and complexity of firms over time accentuated it? Does it vary across national boundaries? Results from the study suggest that conventional wisdom about the incumbent's curse may not always be valid.
