THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

The Design and Analysis of Experiments

Ten years ago, we presented the DeLone and McLean Information Systems (IS) Success Model as a framework and model for measuring the complex-dependent variable in IS research. In this paper, we discuss many of the important IS success research contributions of the last decade, focusing especially on research efforts that apply, validate, challenge, and propose enhancements to our original model. Based on our evaluation of those contributions, we propose minor refinements to the model and propose an updated DeLone and McLean IS Success Model. We discuss the utility of the updated model for measuring e-commerce system success. Finally, we make a series of recommendations regarding current and future measurement of IS success.

The DeLone and McLean Model of Information Systems Success: A Ten-Year Update

Data Mining - Concepts and Techniques.

According to W. Edwards Deming, American companies require nothing less than a transformation of management style and of governmental relations with industry. In Out of the Crisis, originally published in 1982, Deming offers a theory of management based on his famous 14 Points for Management. Management's failure to plan for the future, he claims, brings about loss of market, which brings about loss of jobs. Management must be judged not only by the quarterly dividend, but by innovative plans to stay in business, protect investment, ensure future dividends, and provide more jobs through improved product and service. In simple, direct language, he explains the principles of management transformation and how to apply them.

Data Mining Practical Machine Learning Tools and Techniques

ABSTRACT Mobile advertising accounted for 137 billion dollars or 55% of 2021 U.S. total digital advertising expenditures. Delivery time and tone of language in advertisements (ads) are two little explored characteristics in mobile advertising. This paper examines how morning delivery and the use of a friendly language tone in ads are related to customer purchase intention. Based on survey data from the U.S. population, morning ads with a friendly tone are less irritating and positively influence customer attitude toward mobile learning from the ads, which result in increasing consumer purchase intention. In other words, morning and friendly-toned ads have a positive indirect impact on purchase intention. This research contributes to the body of literature on mobile marketing by providing empirical evidence on the value of delivery time and language tone of mobile communication because such delivery avoids irritating users and increases purchase intention. The developed research model is supported by the appraisal theory of emotions.

How do morning and friendly ads influence mobile advertising? A mediation perspective using appraisal theory

Managers are increasingly confronting the question of how to convey electronic information to e-commerce users in a manner that permits individuals to resolve information search related problems more easily. Information service quality and the associated performance outcomes are challenging to manage during Web-based interactions, primarily because such settings involve several features (i.e., less tangible contact, more uncertainty, differing feedback loops between business and consumers) not found in more traditional exchanges. To capture a broader view of the quality of information offerings in ecommerce settings, the model tested in this study compares the DeLone and McLean (2003) framework, one that includes use as an outcome measure, with a model suggested by Landrum and Prybutok (2004), one that features usefulness as its outcome measure. A random sample of Army Corp of Engineers library customers was performed at two library sites with the Corps. Theoretical and applied implications are developed and discussed.

Rapidly changing business conditions make it difficult to see the future with any degree of certainty. Consequently, many firms have undertaken a thorough self‐examination and reworking of procedures and methods to position themselves to compete in the global marketplace of the 1990s. A crucial element in the changing and improving processes is raising the quality of the product or service the firm provides. Lockheed Martin Tactical Aircraft Systems has a vested interest in changing to meet the new requirements of the aerospace industry and decided to re‐evaluate its business practices, with the goal of increasing productivity while simultaneously increasing quality. Management decided to conduct a large‐scale quality survey throughout the company to understand the company’s current level of quality and the quality perceptions among employees. Reports on the results of that study, with a brief description of the development of the quality survey instrument and the information discovered during the data analysis.
