Introduces a series of articles on the philosophy of science, presented at the 1998 World Congress of Philosophy in Boston, Massachusetts.

This article presents abstracts of papers presented at the twelfth annual meeting of the Society for Psychophysiological Research, which was held at the Hotel Sheraton-Plaza in Boston, Massachusetts on November 9-12, 1972. The paper presented by J.C. Jackson and F.K. Graham of the University of Wisconsin cites threshold intensity effects on two orienting response components. Sokolovian theory suggests that the orienting response should be large near psychophysical threshold, fall to a minimum around 10-20 decibels and then rise again until it is depressed by competition with the defense reflex.

The March/May 2004 special issue of the Journal of Real Estate Finance and Economics presents papers presented at the Maastricht, the Netherlands-Cambridge, Massachusetts Symposium 2002. The Limburg Institute of Financial Economics, the Netherlands hosted this third symposium, which was attended by 43 participants. In all, eleven papers were presented, with nine being selected for publication in this special issue of the Journal of Real Estate Finance and Economics. Of these nine articles, research teams based in the United States write four, another four are from Europe, and one is from the Far East. That means that the special issue of the journal is becoming increasingly international in scope, which underlines the growing quality of research in real estate finance and economics outside of the United States.

The article presents an introduction to the special section related to International Conference on Software Engineering (ICSE'97), published in the August 1998 issue of the journal "IEEE Transactions on Software Engineering." Authors say that ICSE was held in Boston Massachusetts, in the week of May 17-23, 1997. The main goal of the conference was to meet needs and expectations of a large variety of attendees. The program committee of the conference was involved in a comprehensive reviewing process of papers submitted. At the end of this process, three papers were selected for publication. In the first paper, "Evaluating Testing Methods by Delivered Reliability," researchers discuss a method for evaluating the effectiveness of testing, based on a measure of the program reliability after testing. The second paper "Analyzing Partially Implemented Real-Time System," presents a technique for analyzing partially-implemented real-time systems. The third paper "Communication Metrics for Software Development," discusses results of comprehensive experiment whose goal was to evaluate the effectiveness of a set of communication metrics.

Kampmann C. E. (1996) Feedback loop gains and system behavior Proceedings of the 1996 International System Dynamics Conference. System Dynamics Society, Boston, MA, USA In the past two decades, there has been a steady growth of analytical tools that can help the system dynamicist understand and test the behavior of large models. Without such tools, we must resort to simulation experiments and intuition developed from simple, low-order, systems. While this traditional approach has served us well, there is always the danger that we overlook important mechanisms in larger systems or falsely attribute behavior patterns to particular structures. Among these new analytical tools, eigenvalue elasticity analysis (EEA) has received the most attention, perhaps because it rests on a consistent and comprehensive theoretical foundation. The approach involves decomposing system outcomes into characteristic behavior modes, each characterized by an eigenvalue of the linearized system matrix, and then examining how each eigenvalue or behavior mode is affected by small changes in the parameters of the system. The eigenvalue elasticity of a parameter change is a dimensionless number, defined as the fractional change in the eigenvalue resulting from a fractional infinitesimal change in that parameter. Parameters or structural links or loops in the model that have large elasticities are then interpreted as playing a dominant role in that behavior mode. EEA was first used by Nathan Forrester in his doctoral dissertation from 1982. However, it did not receive much attention in the field until the 1996 International System Dynamics Conference, where Christian Kampmann presented a rigorous analysis of the topology of feedback loop structures and how eigenvalue elasticities are related to the strength of individual feedback loops. Since then, an entire strand of research has been devoted to the development and application of EEA, where Kampmann's conference paper remains a seminal reference. Yet until now, the paper has never been published, and researchers have had to rely on private circulation of various drafts of the paper. With this archival publication, we wish to remedy this deficiency in the hope that the work will inspire others to continue developing EEA and further the high standards of analytical rigor that Kampmann's paper represents. Abstract Linking feedback loops and system behavior is part of the foundation of system dynamics, yet the lack of formal tools has so far prevented a systematic application of the concept, except for very simple systems. Having such tools at their disposal would be a great help to analysts in understanding large, complicated simulation models. The paper applies tools from graph theory formally linking individual feedback loop strengths to the system eigenvalues. The significance of a link or a loop gain and an eigenvalue can be expressed in the eigenvalue elasticity, i.e., the relative change of an eigenvalue resulting from a relative change in the gain. The elasticities of individual links and loops may be found through simple matrix operations on the linearized system. Even though the number of feedback loops can grow rapidly with system size, reaching astronomical proportions even for modest systems, a central result of the paper is that one may restrict attention to an independent subset which typically grows only linearly and at most as the square of system size. An algorithm for finding an independent loop set is presented, along with suggestions for how to augment it to select loops with large elasticities. For illustration, the method is applied to a well-known system: the simple long-wave model. Because this model exhibits highly nonlinear behavior, it sheds light on the usefulness of linear methods to nonlinear system. The analysis leads to a more thorough and deeper understanding of the system and sheds new light on conventional wisdom regarding the role of many of the system's feedback loops.

This paper is a revised version of a keynote address delivered at the inaugural International Industrial Organization Conference in Boston, April 2003. It argue that new econometric tools have facilitated the estimation of models with realistic theoretical underpinnings, and because of this, have made empirical 1.0. much more useful. The tools solve computational problems thereby allowing us to make the relationship between the economic model and the estimating equations transparent. This, in turn, enables us to utilize the available data more effectively. It also facilitates robustness analysis and clarifies the assumptions needed to analyze the causes of past events and/or make predictions of the likely impacts of future policy or environmental changes. The paper provides examples illustrating the value of simulation for the estimation of demand systems and of semiparametrics for the estimation of entry models. [ABSTRACT FROM AUTHOR]

The papers presented at the April 1975 conference on economic analysis of political behavior in Cambridge, Massachusetts, are discussed. All of the papers focused on various aspects of the relationship between law and economics. The three papers given at session 1 were all exercises in public choice, and dealt with bureaucracy. The papers in session 2 leaned towards behaviorist political science. The third session consisted of one paper about the legal system. These papers may provide an entry in the traditional political science literature for public choice students with economic backgrounds. In sum, the conference probably performed more of a role in developing interdisciplinary work than individual papers taken individually would imply.

This paper is based on a speech given at the twenty-second annual convention of the Massachusetts League for Nursing, Boston, USA, on 24 September 1975. The author looks at the changing trends in nursing education in the USA, the importance of agreement on the level of entry into nursing and the need for a clear conceptual educational model. The Lehman College nursing programme is used as a prototype for such a model and its curriculum and the role of its nursing graduates as primary care practitioners are discussed and evaluated.

The article presents a preface to the March/May 2004 issue of the Journal of Real Estate Finance and Economics. According to the author he is very pleased to welcome the papers from the third Cambridge, Massachusetts-Maastricht, the Netherlands real estate finance symposium held in 2002, which explore in depth the very real issues that are being faced in how one can most effectively finance the creation and maintenance of the built environment. This is important, the property resource is one of the most important assets that individuals will possess in their lifetime and it is the place in which most wealth is generated in the developed world. The author congratulates and thanks everyone who took part for another successful and stimulating symposium.

The theme of the 2001 annual meeting of the American Historical Association, 'Practices of Historical Narrative', attracted a variety of panels. The following short piece traces one such panel from its conception to presentation. Taking the theme to heart, the panellists created a 'slam' (or reading) of narrative histories written by experienced historians, a graduate student and an undergraduate student, and then opened the session to readings from the audience.

Ancient and modern methods and results of man's efforts to formulate satisfying statements about the ultimate meaning of human life and the nature of the universe were interwoven in the program presented at the sixth international gathering of philosophers held at Harvard University in Cambridge, Massachusetts on September 13-17, 1927. The courts and handsomely assembly rooms of a group of new dormitories located on the banks of the Charles River supplied a delightful atmosphere of academic quiet and gave opportunities for innumerable enjoyable personal contacts. This first New-World session of the Congress was attended by 630 persons, of whom 375 were active members. The 75 foreign delegates came from leading European countries, from Canada, South America, Mexico and India. The tremendous scope of the subjects presented and the abstract or even mystical treatment of many of the topics were in striking contrast to the growing specialization and concreteness observed in the papers presented in national gatherings of social scientists. Inconsistencies in the methods and results of modern philosophy as presented in the discussions of this Congress would justify a modification of this statement to the more modest claim that philosophy may enlarge the outlook of the human spirit by stimulating speculative efforts to achieve this tremendous program.
