What Can We Learn about the Ontology of Space and Time from the Theory of Relativity?
No full textMany have inferred from the theory of relativity philosophical conclusions that are unjustified, such as that geometry is conventional or that spacetime should be reduced to the causal order among events. Other conclusions from the theory are justified, such as the "entanglement" of space with time and that space and time are deeply connected to matter and to the causal structure of the world. This chapter discusses what exactly the theories of special and general relativity tell us about space and time. What are the features that are genuinely novel, that follow from the new theories, that are part and parcel of a literal understanding of the theories, and that are robust in the sense of not being faced with contradictory "morals" that can also be drawn from these new theories?

No full textThere are no universal rules for induction
No full textIn a material theory of induction, inductive inferences are warranted by facts that prevail locally. This approach, it is urged, is preferable to formal theories of induction in which the good inductive inferences are delineated as those conforming to universal schemas. An inductive inference problem concerning indeterministic, nonprobabilistic systems in physics is posed, and it is argued that Bayesians cannot responsibly analyze it, thereby demonstrating that the probability calculus is not the universal logic of induction.

The Inductive Significance of Observationally Indistinguishable Spacetimes
No full textResults on the observational indistinguishability of spacetimes demonstrate the impossibility of determining by deductive inference which is our spacetime, no matter how extensive a portion of the spacetime is observed. These results do not illustrate an underdetermination of theory by evidence, since they make no decision between competing theories and they make little contact with the inductive considerations that must ground such a decision. Rather, these results express a variety of indeterminism in which a specification of the observable past always fails to fix the remainder of a spacetime. This form of indeterminism is more troubling than the familiar indeterminism of quantum theory. The inductive inferences that can discriminate among the different spacetime extensions of the observed past are here called “opaque,” which means that we cannot readily see the warrant that lies behind them
Telerehabilitation Practice: A Curricular Imperative for Future Audiologists
No full textEffective telerehabilitation services in audiology can now be delivered using synchronous; store and forward methods; or a hybrid (synchronous and asynchronous) approach. While reimbursement for telerehabilitation is not yet robust and the practice may be limited by current state licensure guidelines, telerehabilitation is a viable current and future practice option. It is therefore incumbent upon university training programs to include telerehabilitation options in audiology training curricula. This presentation reviews the current state-of-the-art in audiology based telerehabiliation, and then presents elements for a multi-pronged curricula: 1. Introduction to Telerehabilitation; 2. Telerehabilitation Technologies; 3. Telerehabilitation Practice and 4. Tele-audiology Technologies and Techniques. Finally, professional resources are presented
A different kind of archival security: Three cases
No full textArchival security is not just about guarding against theft and vandalism; it is about accountability and ethics and the potential challenges to archives and archivists. This essay considers three cases -the ownership and control of the records of indigenous peoples, the use of records of the U.S. Supreme Court, and the misadminstration of electronic mail messages to the White House. © Taylor & Francis Group, LLC
Telerehabilitation E-Dissemination Opportunities: Three Vehicles for Academic Public Service
No full textThe University of Pittsburgh RERC on Telerehabilitation identified three previously under-utilized “web-based spaces” to feature telerehabilitation-based efforts. This presentation will feature efforts to promote telerehabilitation via: 1. Wikipedia (supported by the efforts of the ATA SIG on Telerehabilitation) 2. Google’s Knol application and, 3. Open Journal Systems developed by the Public Knowledge Project (pkp.sfu.ca). Each is free to the public and affords opportunities for faculty and practitioners to engage in academic public service. We will compare and contrast these vehicles’ ease of use, immediacy, accessibility challenges, and quality control; and present product exemplars --- including a new, electronic-only, open access peer-reviewed journal (International Journal of Telerehabilitation) published by the University of Pittsburgh’s University Library System and scheduled to launch Spring/Summer 2009. Each of these web-based formats provides opportunities to engage in academic public service
Addictive links: The motivational value of adaptive link annotation
No full textAdaptive link annotation is a popular adaptive navigation support technology. Empirical studies of adaptive annotation in the educational context have demonstrated that it can help students to acquire knowledge faster, improve learning outcomes, reduce navigational overhead, and encourage non-sequential navigation. In this paper, we present our exploration of a lesser known effect of adaptive annotation, its ability to significantly increase students' motivation to work with non-mandatory educational content. We explored this effect and confirmed its significance in the context of two different adaptive hypermedia systems. The paper presents and discusses the results of our work
Unpleasant Things: Teaching Advocacy in Archival Education Programs
No full textAs graduate archival education programs have grown in scope, the variety of courses offered has changed to include some that prepare students to grapple with challenging and sometimes controversial aspects of the profession. This paper offers insights gained from teaching a course on archival advocacy, one that expanded over more than a decade from a focus on access to public outreach to ethical issues. This shift in focus created particular problems in engaging students who come to the graduate program with basic presuppositions about archival work that do not often mesh with the reality of this professional community; challenges also arise because of the kinds of training students expect from professional schools within the university. The essay places this course in the context of the modern university and the changing archival community and considers the challenges and potential successes of engaging graduate students within a professional school
Digital Curation and the Citizen Archivist
No full textThe increasing array and power of personal digital recordkeeping systems promises both to make it more difficult for established archives to acquire personal and family archives and less likely that individuals might wish to donate personal and family digital archives to archives, libraries, museums, and other institutions serving as documentary repositories. This paper provides a conceptual argument for how projects such as the Digital Curation one ought to consider developing spinoffs for archivists training private citizens how to preserve, manage, and use digital personal and family archives. Rethinking how we approach the public, which will increasingly face difficult challenges in caring for their digital archives, also brings with it substantial promise in informing them about the nature and importance of the archival mission. Can the Digital Curation project provide tools that canbe used for working with the public
