AbstractIn this paper, we try to identify the parameters for two elementary epidemic models, the so-called SI- and SIS-models, via non-linear regression using data of the COVID-19 pandemic. This is done based on the data for the number of daily infections. Studying the history of predictions made, we attempt to estimate their reliability concerning the future course of the epidemic. We validate this procedure using data for the case numbers in China and South Korea. Then we apply it in order to find predictions for Germany, Italy and the United States. The results are encouraging, but no final judgment on the validity of the procedure can yet be made.

The Future of Art Bibliography (FAB) initiative developed out of various conversations among colleagues in the United States and Europe. Events in the art historical community, including limited funding resources for art libraries and projects internationally, and the cessation of the Getty’s support for the production of the Bibliography of the history of art (BHA) provided the catalyst for the Kress Foundation grant to the Getty Research Institute. A series of international meetings of art librarians, art historians, publishers and information specialists ensued. The goal was to review current practices, take stock of changes, and seriously consider developing more sustainable and collaborative ways of supporting the bibliography of art history in the future.

AbstractSince the first study of communication between patient and computer was performed at the University of Wisconsin in 1965, programs for patient-computer dialogue have been developed, implemented, and studied in numerous settings in the United States and abroad, and the results have been encouraging. This review presents a brief history of patient-computer dialogue together with suggested guidelines for programs in the future.

Abstract The 2008 Financial Recession was one of the most significant fiscal downturns in the history of the United States. Considering that the world is in the midst of a global pandemic which may lead to another adverse economic climate, I believe that looking back at the causes of the 2008 Financial Recession is recommended. This may assist administrators to avoid the missteps which sparked this down economy in the future. By reading this paper, readers will also learn about the demographics effected by the recession and the Dodd-Frank Act, which was drafted to combat future occurrences of this nature.

This chapter explores Presbyterian influences and involvement in higher education. It begins by using Princeton as an historic lens to examine the “Presbyterian ideals” of reason and education, liberty, and differentiation. The Presbyterian regard for freedom of thought and intellectual edification produced denominational schools throughout the history of higher education, especially in the United States, that differed substantially in their overarching philosophies, approaches to learning, curricula, and emphases on Christian piety. The second part of the chapter identifies the proliferating diversity at the intersection of Presbyterianism and the higher education landscape in the twentieth century. It describes differentiation by theology, denominations, geography, and culture. The chapter ends with brief ruminations on the future roles and stability of Presbyterian higher education.

The article explores reasons for the lack of success of digital electronic shelf labels (ESLs) in US retail settings. It suggests that these reasons can be traced by referring to the triple meaning of ‘digital’: ‘Digital’ now means electronic, but the word also long encompassed numerals – a digit is a number – and body parts – digitus is the Latin word for the finger, that is, the index we use to point at things or manipulate them. The current fate of ESLs is linked to a long history that combined these three dimensions. The study unfolds along a twofold narrative. First, it reviews the recent introduction of ESLs in the United States based on the reading of papers and advertisements published in Progressive Grocer, a leading trade press magazine. Then, it goes ‘back to the future’ by exploring the roots of ESLs over a century. This historical study is based on the analysis of the evolution of US price tag patents (through a network study of patents citations and their evolution); the network analysis is complemented with the history of the US price tag market (through the knowledge gained from Progressive Grocer). The results show that digital price fixing depends on past and present systems and infrastructures, cost constraints and payback schemes, legal frameworks, and social projects.

Exploring sociological literature across almost three-quarters of a century, this chapter maps the origins and trajectory of sociologists’ exploration of the parish from the 1950s to today. From its contentious start to its largely applied orientation today, the chapter highlights several eras of parish research and argues that our current lack of sociological research on Catholic parishes can be traced to the tenuous relationship between the academy and the institutional Catholic Church. The chapter concludes by asserting that parish studies can be simultaneously good for the academy and good for the church. The future of sociological studies of the parish rest upon the willingness of both the academy and the church to accept this proposition.

This chapter sketches the history of U.S–French electronic communications prior to the rise of U.S.–French radio broadcasting. Focusing primarily on France, it analyzes the anticipatory and reactive discourses to live interwar transatlantic broadcast connectivity with the United States. The period saw two contrasting, nationally inflected techno-aesthetics take shape in America and France that defined excellence in radio. In America, technological power, abundance, and high-speed execution demonstrated professional competence and efficiency. The French emphasized quality, accepted scarcity, and valued deliberate speed. More than extensions of preexisting differences in U.S. and French cultural conventions these broadcast paradigms emerged relationally and cross-nationally to shape the future of U.S.–French broadcast interaction and the character of an evolving international medium.

This chapter describes the history of the development and use of electronic resources in libraries in the United States. It provides an overview of the major developments in the field with a focus on library catalogs, electronic databases, e-books and e-serials. The chapter is intended to convey the broad sweep of change that has characterized these electronic resources from the 1960’s to the early 2000’s, as well as a sense of the underlying issues that remain the same. The author hopes that an understanding of the history of the development and use of these resources may lead to a better understanding of the current environment and provide inspiration for the future.
