The Proliferation Security Initiative was launched in 2003 by the Bush administration right after the So San incident. Its primary purpose is to interdict the spread of WMD and their delivery systems. Due to the provocative and challenging characteristics of the Initiative, which are inconsistent with conventional international law, there are some objections against the Initiative. This paper answers the highly topical questions regarding the Initiative in three parts. The first part addresses the origin and development of the Initiative. The second part critically analyzes the background of the Initiative such as the neoconservative ideology of the Bush administration and its world strategy, international terrorism, and the U.S. arms industry. The third part scrutinizes questions concerning the preemptive use of force for self-defense and the interdiction of foreign vessels on the territorial and high seas. The Initiative is also examined from a viewpoint of customary international law.

We introduce a method of identifying evidence of shocks in the X-ray emitting gas in clusters of galaxies. Using information from synthetic observations of simulated clusters, we do a blind search of the synthetic image plane. The locations of likely shocks found using this method closely match those of shocks identified in the simulation hydrodynamic data. Though this method assumes nothing about the geometry of the shocks, the general distribution of shocks as a function of Mach number in the cluster hydrodynamic data can be extracted via this method. Characterization of the cluster shock distribution is critical to understanding production of cosmic rays in clusters and the use of shocks as dynamical tracers.

L1 and L2 summaries written by Korean university students in an EFL writing class were studied to determine the causes of instances of “plagiarism.” Summaries in both L1 and L2 were evaluated holistically along with seven essays in L2. It was found that more proficient writers in L1 and L2 tend to demonstrate less Reliance on the Source Text1); and a good amount of Reliance was also present in L1 as well as L2, suggesting that L2 interference is not the only cause of Reliance. These findings indicate a relation between Reliance on the Source text and writing ability both in L1 and L2. Moreover, a closer look at instances of Reliance often revealed efforts by the writers to integrate source text material into their own texts, though these attempts often seemed like “plagiarism” to writing teachers. However, Reliance in these cases may not be plagiarism per se from students’ point of view. The results are expected to help teachers understand the causes and nature of students’Reliance on the Source text in the writing instruction.

This study addresses the phenomenon of foundational meta-narratives in North Korea’s discourses. Meta-narratives are understood here as a totalizing cultural narrative schema which orders and explains knowledge and experience. On the national level, meta-narratives refer to those over-arching, all-encompassing myths and stories that contain the historical knowledge of a country’s foundational history. This paper discusses three particularly important meta-narratives permeating North Korea’s contemporary political and cultural discourses: the meta-narrative of national ruin, of (Kim Il Sung’s) armed resistance and of constant threat of external aggression. Providing both positive and negative frames of reference, the study shows how these meta-narratives are strategically employed in contemporary discourses as ‘historical contextualizations’ in which particular interpretations of the past are used as arguments for political actions in the present, and, with recourse to history, produce a normative frame for evaluating contemporary events and actions. At the same time, the historical references and myths contained in those meta-narratives play an important role in establishing identity and fostering integration, for they level differences within the North Korean community and thus construct sameness and communality.

Anomalous X-ray pulsars (AXPs) are thought to be magnetars which are young isolated neutron stars with extremely strongmagnetic fields of >1014 Gauss. Their tremendous magnetic fields inferred from the spin parameters provide a huge energyreservoir to power the observed X-ray emission. High-energy emission above 0.3 MeV has never been detected despiteintensive search. Here, we present the possible Fermi Large Area Telescope (LAT) detection of γ-ray pulsations above 200MeV from the AXP, 1E 2259+586, which puts the current theoretical models of γ-ray emission mechanisms of magnetars intochallenge. We speculate that the high-energy γ-rays originate from the outer magnetosphere of the magnetar.
