The transient behavior of the fundamental amplitude of the photorefractive space-charge field is derived without restrictions within the band transport model. The two-wave mixing pulse excitation regime is simulated in different ranges of the main parameters, especially in the region where the nonlinear processes become important. The formation and decay of the field are analyzed, and for diffe...

In a study that focused on adolescent girls' health issues within their dating relationships, we found that nonstructured focus group conversation can be augmented with structured strategies to generate a nonthreatening environment in which participants are enabled to co-create an understanding of their experiences. The use of free writing, role playing, and body tracing helped raise participan...

Local electrochemical phenomena on the surfaces of the LaAlO(3)-SrTiO(3) heterostructure are explored using unipolar and bipolar dynamic electrochemical strain microscopy (D-ESM). The D-ESM suggests the presence of at least two distinct electrochemical processes, including fast reversible low-voltage process and slow high-voltage process. The latter process is associated with static surface def...

The purpose of this paper is to explore the use of n-gram analysis to analyze instructor and student comments elicited within My Reviewers, a web-based learning environment. Shown to be informative in a wide variety of applications, n-gram analysis is of interest in determining concept proliferation in topics, purposes, terminologies, and rubrics used in writing courses. As the present study de...

Can psychotherapy reduce the incidence of health problems? A general model of psychosomatics assumes that inhibiting or holding back one's thoughts, feelings, and behaviors is associated with long-term stress and disease. Actively confronting upsetting experiences--through writing or talking-is hypothesized to reduce the negative effects of inhibition. Fifty healthy undergraduates were assigned...

Mobile agents research is clearly aiming towards imposing agent based development as the next generation of tools for writing software. This paper comes with its own contribution to this global goal by introducing a novel unifying framework meant to bring simplicity and interoperability to and among agent platforms as we know them today. In addition to this, we also introduce a set of agent beh...

Calvin is a transaction scheduling and replication management layer for distributed storage systems. By first writing transaction requests to a durable, replicated log, and then using a concurrency control mechanism that emulates a deterministic serial execution of the log’s transaction requests, Calvin supports strongly consistent replication and fully ACID distributed transactions while incur...

T heologian John Shea, STD, writing several years ago about CHA's Mission-Centered Leadership Competency Model, said that in health ministry the first step from faith to practicality—that is, concrete action on behalf of mission—is values. "Faith convictions and narratives are expressed in the full-blown religious language of the Catholic tradition, for example, God, Christ, sin, redemption, ch...
