The Challenges of Conceptualizing Terrorism

Abstract: This analysis begins by exploring various reasons that the concept of terrorism has evaded a widely agreed upon definition for so long despite the efforts of so many writers. Emphasis is placed on the difficulties associated with all “essentially contested concepts.” In addition, the investigation calls attention to such problems as conceptual “stretching” and “traveling.” In an effort to solve the difficulties, the inquiry attempts to determine a consensus definition of terrorism by turning to an empirical analysis of how the term has been employed by academics over the years. Specifically, the well-known definition developed by Alex Schmid, based upon responses to a questionnaire he circulated in 1985, is compared with the way the concept has been employed by contributors to the major journals in the field: Terrorism, Studies in Conflict and Terrorism, and Terrorism and Political Violence. The 22 “definitional elements” of which Schmid's definition is composed are compared to the frequency with which th...

Finding the philosophical core: a review of stephen c. pepper's world hypotheses: a study in evidence1

Abstract: Behavior analysis has always had significant conflicts with other psychological perspectives. At their most fundamental level, these conflicts are often philosophical, concerning such issues as the nature of the human and the purposes of science. Why are these the conflicts? What, if anything, can we do about them? Can we resolve them? Can we avoid them altogether by simply abandoning philosophy? To answer these questions, we must be clear about the philosophy underlying behavior analysis compared to those of other perspectives. To be clear is difficult, however, because the assumptions and postulates of the position are not deliberately and unambiguously laid down. Fundamental assumptions, specific theories, and historical accidents are too often discussed concurrently and without adequate differentiation in behavior-analytic expositions. Skinner's philosophical writings are especially prone to this difficulty, perhaps because he is so extensively involved with so many nonphilosophical aspects of the field. In 1942 Stephen C. Pepper, a philosopher and aestheticist, published World Hypotheses: A Study in Evidence. His central insight was that philosophical systems cluster around a few core models, or \"world hypotheses,\" drawn from common sense. His strategy was to ignore details and personalities, and instead to present the central tenets of each world view in a general way. He used his own terms to describe most of these tenets, avoiding excess or parochial meanings. He quoted and cited very little. His style permits an understanding of

The mobility of zirconium and other immobile' elements during hydrothermal alteration

Abstract: Development of zircon and other Zr phases in hydrothermal deposits indicates that Zr can be highly mobile in these systems. Mobility is most common in, but not restricted to, F-rich hydrothermal systems related to alkalic, F-rich igneous suites; these suites can range from peralkaline through metaluminous to peraluminous. A few examples are neither alkalic nor F rich. Three locations in the Trans-Pecos Magmatic Province, Texas, U.S.A., demonstrate this hydrothermal Zr mobility. All three igneous systems are alkalic and F rich but vary in alkali/Al ratios. Peralkaline rhyolites and trachytes in the Christmas Mountains contain as much as 2100 ppm Zr, mostly in aegirine or arfvedsonite; zircon is rare or absent
