The Fate Of Cannibalized Fundamental-Plane Ellipticals, Martin D. Weinberg Jul 1996

The Fate Of Cannibalized Fundamental-Plane Ellipticals, Martin D. Weinberg

Astronomy Department Faculty Publication Series

Evolution and disruption of galaxies orbiting in the gravitational field of a larger cluster galaxy are driven by three coupled mechanisms: 1) the heating due to its time dependent motion in the primary; 2) mass loss due to the tidal strain field; and 3) orbital decay. Previous work demonstrated that tidal heating is effective well inside the impulse approximation limit. Not only does the overall energy increase over previous predictions, but the work is done deep inside the secondary galaxy, e.g. at or inside the half mass radius in most cases. Here, these ideas applied to cannibalization of elliptical galaxies …


The Quantum Theory Of General Relativity At Low Energies, John Donoghue Jul 1996

The Quantum Theory Of General Relativity At Low Energies, John Donoghue

Physics Department Faculty Publication Series

In quantum field theory there is now a well developed technique, effective field theory, which allows one to obtain low energy quantum predictions in “non-renormalizable” theories, using only the degrees of freedom and interactions appropriate for those energies. Whether or not general relativity is truly fundamental, at low energies it is automatically described as a quantum effective field theory and this allows a consistent framework for quantum gravity at ordinary energies. I briefly describe the nature and limits of the technique.

Using Informational Labeling To Influence The Market For Quality In Food Products, Julie Caswell Jul 1996

Using Informational Labeling To Influence The Market For Quality In Food Products, Julie Caswell

Julie Caswell

In the United States, the federal government is increasingly using requirements for informational labeling on food products to influence 1) consumers' knowledge and purchasing patterns and 2) manufacturers' product offerings and marketing practices. We discuss the economic rationale behind these regulations and issues related to judging their success or failure.


Ethical Problems And Dilemmas In The Interaction Between Science And Media, David Resnik Jul 1996

Ethical Problems And Dilemmas In The Interaction Between Science And Media, David Resnik

Ethics in Science and Engineering National Clearinghouse

Science and the media are not strange bedfellows since they both gather information, value accuracy and objectivity, and recognize their enormous social responsibilities. The public often benefits from interactions between science and the media, and these two institutions often complement each other. However, since they have different standards, goals, expertises, competencies, and funding sources, science and the media can sometimes interact in ways that produce unintended, adverse consequences for the public. Sometimes the public may become misinformed, deceived, or confused as a result of the media's coverage of science. This unfortunate effect can lead to poor policy decisions, ill-informed public …


Research Vs. Teaching: An Ethical Dilemma For The Academic Physicist, Alvin M. Saperstein Jul 1996

Research Vs. Teaching: An Ethical Dilemma For The Academic Physicist, Alvin M. Saperstein

Ethics in Science and Engineering National Clearinghouse

The usual discussions of academic ethics and freedom revolve around the issues of what we may teach. Here, I'm concerned with how we teach and examine. Thus this paper is concerned with process rather than substance--perhaps an unusual concern for an academic but currently of interest to me, having recently served a year in the federal bureaucracy where process is dominant over substance.

A physician who knew of improved procedures to facilitate the health of a patient but chose to use older, proven less effective, means, purely for his/her own convenience, would clearly be guilty of medical malpractice--unethical behavior. I …


Ethics, Physics, And Public Policy, Tina Kaarsberg Jul 1996

Ethics, Physics, And Public Policy, Tina Kaarsberg

Ethics in Science and Engineering National Clearinghouse

This paper discusses the ethical aspects of physicists', and the physics community's involvement in public policy. The work of individual physicists is often quite distant from any societal impact and thus public policy is not normally considered an important ethical consideration for individual physicists. However, in light of the great societal impact of physics-based technologies, the physics profession, by definition, has a major impact on public policy. In addition, most physicists in the U.S. benefited considerably from public funding in their physics education, and many continue to depend upon federal and state funding. Thus, there is a strong ethical argument …


Should Physics Students Take A Course In Ethics? Physicists Respond, Bonnie Wylo, Marshall Thomsen Jul 1996

Should Physics Students Take A Course In Ethics? Physicists Respond, Bonnie Wylo, Marshall Thomsen

Ethics in Science and Engineering National Clearinghouse

Should physics students take a course in ethics? A National Science Foundation grant was written by the authors in an attempt (in part) to answer this question. One might first ask, why might physics students take a course in ethics? There are three reasons that might combine to persuade one of the necessity. First, the formal training can be quite practical and useful in the daily life of a physicist, as discussed below. Second, the National Science Teachers Association suggests an ethical component in the training of high school physics teachers (NSTA Standards for Science Teacher Preparation, available at www.nsta.org). …


Publication Practices In Physics, Marshall Thomsen Jul 1996

Publication Practices In Physics, Marshall Thomsen

Ethics in Science and Engineering National Clearinghouse

Publication of research results in scholarly journals plays an important role in the scientific community. These publications provide both a means for dissemination of new results and a means for evaluating the quality of scientific work and the scientists who perform it. This paper will examine motivations for publishing, ethical issues in publication, some relevant ethical codes, and some corrective measures that have been taken to shore up areas of ethical concern. Finally, the impact of new communications technologies on the future of publication will be considered.


Ethical Issues In Physics: Ethical Harassment, Caroline L. Herzenberg Jul 1996

Ethical Issues In Physics: Ethical Harassment, Caroline L. Herzenberg

Ethics in Science and Engineering National Clearinghouse

The concept of ethical harassment is identified and discussed. It is proposed that we search for societal mechanisms that may lead to some progress in the curtailment of ethical harassment. It is proposed that the right to act ethically should be regarded as a fundamental human and professional right.
