Eco-terrorism or Eco-tage: An Argument for the Proper Frame
What does the term “terrorism” mean? Is it accurate to lump illegal acts that destroy property but carefully avoid harming people into the same category as acts clearly intended to kill? Is this a difference of kind or just of degree? While we (the authors) don\u27t generally endorse the destruction of property as a method of generating social change, we believe that the destruction of property is fundamentally different from the intentional killing of people; therefore, to label acts of obstruction, trespassing, vandalism, sabotage, or arson as “terrorism” is inaccurate and has the potential to damage one\u27s understanding of real acts of terrorism, thereby reducing the potency of the term. We started this project with a hunch. In recent years, we have observed frequent use of the term “eco-terrorism,” in the news media and in conversations, in reference to the acts of environmentalists. Our observations were anecdotal, and we wanted to be sure they were accurate. We found no literature analyzing cultural acceptance of the term “eco-terrorism”; therefore, before embarking on an ethical analysis of this phenomenon, we set out to confirm our casual observation that the term was widely used in the United States. We conducted an analysis of the use of the term in US newspapers across a period of nearly 11 years. Our analysis indicates broad acceptance of the term among both journalists and their sources, making it all the more important to understand both the history and the implications of labeling obstruction, trespassing, vandalism, sabotage, and arson as “eco-terrorism.
Motivating a volunteer workforce in the criminal justice system
The Optional Protocol to the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (OPCAT) requires that police detention processes are monitored and inspected. The United Kingdom is partially ensuring this provision through the use of an existing independent volunteer workforce. This research explores the conditions required for the effective use of this volunteer workforce through 12 semi-structured interviews. An Interpretative Phenomenological Analysis was used that initially generated 46 motivator codes that were clustered into six themes of volunteer motivation consisting of: personal affect, personal growth, social goals, altruistic, activity and values. Ten demotivators were also revealed through the interviews. The implications of these findings for volunteer motivation and how organisations may capitalise on this are discusse
Basic statistical analyses of candidate nickel-hydrogen cells for the Space Station Freedom
Nickel-Hydrogen (Ni/H2) secondary batteries will be implemented as a power source for the Space Station Freedom as well as for other NASA missions. Consequently, characterization tests of Ni/H2 cells from Eagle-Picher, Whittaker-Yardney, and Hughes were completed at the NASA Lewis Research Center. Watt-hour efficiencies of each Ni/H2 cell were measured for regulated charge and discharge cycles as a function of temperature, charge rate, discharge rate, and state of charge. Temperatures ranged from -5 C to 30 C, charge rates ranged from C/10 to 1C, discharge rates ranged from C/10 to 2C, and states of charge ranged from 20 percent to 100 percent. Results from regression analyses and analyses of mean watt-hour efficiencies demonstrated that overall performance was best at temperatures between 10 C and 20 C while the discharge rate correlated most strongly with watt-hour efficiency. In general, the cell with back-to-back electrode arrangement, single stack, 26 percent KOH, and serrated zircar separator and the cell with a recirculating electrode arrangement, unit stack, 31 percent KOH, zircar separators performed best
HRXRD study of the theoretical densities of novel reactive sintered boride candidate neutron shielding materials
Reactive Sintered Borides (RSBs) are novel borocarbide materials derived from FeCr-based cemented tungsten (FeCr-cWCs) show considerable promise as compact radiation armour for proposed spherical tokamak,[1],[2],[3],[4],[5]. Six candidate compositions (four RSBs, two cWCs) were evaluated by high-resolution X-ray diffraction (XRD), inductively coupled plasma (ICP), energy dispersive X-ray analysis (EDX) and scanning electron microscopy (SEM) to determine the atomic composition, phase presence, and theoretical density.
RSB compositions were evaluated with initial boron contents equivalent to 25 at% 30 at%. All RSB compositions showed delamination and carbon enrichment in the bulk relative to the surface, consistent with non-optimal binder removal and insufficient sintering time. Phase abundance within RSBs derived from powder XRD was dominated by iron tungsten borides (FeWB/FeW2B2), tungsten borides (W2B5/WB) and iron borides. The most optimal RSB composition (B5T522W) with respect to physical properties and highest ρ/ρtheo had ρtheo = 12.59 ± 0.01 g cm-3 for ρ/ρtheo = 99.3% and had the weigh-in and post-sintered W : B : Fe abundance closest to 1 : 1 : 1. This work indicates that despite their novelty, RSB materials can be optimized and in principle be processed using existing cWC processing routes
Discovering and quantifying nontrivial fixed points in multi-field models
We use the functional renormalization group and the -expansion
concertedly to explore multicritical universality classes for coupled
vector-field models in three Euclidean dimensions.
Exploiting the complementary strengths of these two methods we show how to make
progress in theories with large numbers of interactions, and a large number of
possible symmetry-breaking patterns. For the three- and four-field models we
find a new fixed point that arises from the mutual interaction between
different field sectors, and we establish the absence of infrared-stable fixed
point solutions for the regime of small . Moreover, we explore these
systems as toy models for theories that are both asymptotically safe and
infrared complete. In particular, we show that these models exhibit complete
renormalization group trajectories that begin and end at nontrivial fixed
points.Comment: 10 pages, 6 figures; minor changes, as published in EPJ
