From Confederate Deserter to Decorated Veteran Bible Scholar: Exploring the Enigmatic Life of C.I. Scofield 1861-1921.
Cyrus Ingerson Scofield portrayed himself as a decorated Confederate veteran, a successful lawyer, and a Bible scholar who was providentially destined to edit his 1909 dispensational opus, The Scofield Reference Bible. This thesis offers a multilayered image of Dr. Scofield\u27s life by considering political and regional influences, racial and gender attitudes, and religious views he encountered between 1861 and 1921. This study includes an examination of his participation in the American Civil War including his desertion of the South in 1862. After becoming a Union loyalist, Scofield excelled as a lawyer and Republican politician before corruption rumors radically altered his life in 1874. By 1882, he emerged as a minister in Dallas, Texas where he built an image as a Confederate veteran and Bible scholar. Drawing on Scofield\u27s manuscripts and other sources, this study shows the self-aggrandizing Bible editor consistently adapted his life and rhetoric to his regional and social circumstances
Relative Function: Nuclear Brain Imaging in United States Courts
Neuropsychological testing--medical imaging of the brain structure and function--allows the expert to inform the court on the brain structure and function of the forensic examinee. Supported by extensive clinical use, neuropsychological testing and structural imaging in the form of computerized tomography and structural magnetic resonance imaging have achieved general acceptance in court. However, functional imaging such as functional MRI and nuclear medicine techniques, such as positron emission tomography (PET), have faced more admissibility challenges. While functional imaging is becoming an increasingly important tool in assessing neuropsychiatric illness, we surmise that evidentiary challenges are largely related to the phase of trial in which the nuclear study is offered as evidence. This article will review the basic science of functional nuclear imaging including PET and single photon emission computed tomography. We will then review cases where admissibility of these techniques has been challenged and consider whether and how nuclear brain imaging can influence the outcome of the trial
Verifications Of The Kalman Conjecture Based On Locus Curvature
The Kaiman conjecture is verified for certain transfer functions with only negative real poles and no numerator dynamics. The results are based on the off-axis circle criterion of Cho and Narendra and a consideration of the curvature of the Nyquist locus of the transfer function. Copyright © 1974, IEEE.

Tale Of A Non-Interacting Additive In A Lithium-Ion Electrolyte: Effect On Ionic Speciation And Electrochemical Properties
New lithium electrolytes compatible with high energy density cells are critical for lithium metal battery applications, but dendrite formation associated with the use of dilute organic electrolytes complicates their realization. High-concentration electrolytes mitigate some of the issues of the electrolytes but introduce additional problems, such as low conductivity and high cost. Hence, pseudo-concentrated electrolytes, wherein a co-solvent is added to a dilute electrolyte, have been presented as a possible alternative to both dilute and concentrated electrolytes. However, the effect that the co-solvent has on the electrolyte properties at both macroscopic and microscopic levels is unknown. Here, a study of the structure and electrochemical properties of two electrolytes as a function of co-solvent concentration is presented using an array of spectroscopies (FTIR, ATR-FTIR, and nuclear magnetic resonance) and computational methods (density functional theory calculations). The chosen electrolytes comprised two different lithium salts (LiPF6 and LiTFSI) in a mixture of dimethyl carbonate (DMC) with 1,1,1,3,3-pentafluorobutane (PFB) as the co-solvent. Our results show that in the case of the LiPF6/DMC electrolyte, the addition of a co-solvent (PFB) with a larger dielectric constant results in the strengthening of the lithium-anion interaction and the formation of aggregate species since PFB does not interact with the anion. Conversely, in the LiTFSI/DMC electrolyte, the co-solvent appears to interact with the anion via hydrogen bonds, which leads to the dissociation of contact ion pairs. The change in ionic speciation of the electrolytes upon addition of PFB provides a reasonable framework to explain the different trends in both the bulk and interfacial macroscopic properties, such as conductivity, viscosity, and electrochemical stability. Overall, our findings demonstrate that the interactions between the anion and the co-solvent must be taken into consideration when adding a co-solvent because they play a major role in determining the final electrolyte properties

Finding the Five R\u27s in Exemplary Agricultural Publication Capstone Courses
This study sought to characterize three exemplary agricultural communications magazine capstone courses at three different universities. The purpose of the research was to describe the characteristics leading to the courses’ success. Following a qualitative research approach, the investigator conducted personal interviews with students and instructors in each course, made field observations, and examined syllabi. The interviews were crafted after Andreasen’s (2004) Five R’s model for quality capstone courses. Important characteristics of the three exemplary magazine capstone courses included (1) student responsibility for the entire magazine production process, (2) high-quality standards that were comparable to those expected in industry, (3) interaction with professionals in the publication and printing industry, and (4) the revisiting of previously fragmented knowledge through refresher lessons. Further, because capstone courses often serve as a rigorous “rite of passage” for agricultural communications students as they transition to their professional careers, students need positive reinforcement to make it through key moments in the course. These moments of positive reinforcement helped students gain conf idence in their skills as professionals. The researchers concluded that providing students with a real-world experience and positive reinforcement was essential to the success of these courses. Students felt expectations for deadlines, quality of work, and attendance was similar to what they would expect in the workforce. In turn, they thought this would help them prepare to enter into their careers. Recommendations for practice include integrating these characteristics into new and existing magazine capstone courses. In addition to these practical recommendations, the results also lead to the recommendation of modifications to Andreasen’s (2004) Five R’s model with changes focusing on noise and feedback
Depth-varying rupture properties of subduction zone megathrust faults
Subduction zone plate boundary megathrust faults accommodate relative plate motions with spatially varying sliding behavior. The 2004 Sumatra-Andaman (M_w 9.2), 2010 Chile (Mw 8.8), and 2011 Tohoku (M_w 9.0) great earthquakes had similar depth variations in seismic wave radiation across their wide rupture zones – coherent teleseismic short-period radiation preferentially emanated from the deeper portion of the megathrusts whereas the largest fault displacements occurred at shallower depths but produced relatively little coherent short-period radiation. We represent these and other depth-varying seismic characteristics with four distinct failure domains extending along the megathrust from the trench to the downdip edge of the seismogenic zone. We designate the portion of the megathrust less than 15 km below the ocean surface as domain A, the region of tsunami earthquakes. From 15 to ∼35 km deep, large earthquake displacements occur over large-scale regions with only modest coherent short-period radiation, in what we designate as domain B. Rupture of smaller isolated megathrust patches dominate in domain C, which extends from ∼35 to 55 km deep. These isolated patches produce bursts of coherent short-period energy both in great ruptures and in smaller, sometimes repeating, moderate-size events. For the 2011 Tohoku earthquake, the sites of coherent teleseismic short-period radiation are close to areas where local strong ground motions originated. Domain D, found at depths of 30–45 km in subduction zones where relatively young oceanic lithosphere is being underthrust with shallow plate dip, is represented by the occurrence of low-frequency earthquakes, seismic tremor, and slow slip events in a transition zone to stable sliding or ductile flow below the seismogenic zone

A new approach to generating research-quality data through citizen science: The USA National Phenology Monitoring System
Phenology is one of the most sensitive biological responses to climate change, and recent changes in phenology have the potential to shake up ecosystems. In some cases, it appears they already are. Thus, for ecological reasons it is critical that we improve our understanding of species’ phenologies and how these phenologies are responding to recent, rapid climate change. Phenological events like flowering and bird migrations are easy to observe, culturally important, and, at a fundamental level, naturally inspire human curiosity— thus providing an excellent opportunity to engage citizen scientists. The USA National Phenology Network has recently initiated a national effort to encourage people at different levels of expertise—from backyard naturalists to professional scientists—to observe phenological events and contribute to a national database that will be used to greatly improve our understanding of spatio-temporal variation in phenology and associated phenological responses to climate change.

Traditional phenological observation protocols identify specific dates at which individual phenological events are observed. The scientific usefulness of long-term phenological observations could be improved with a more carefully structured protocol. At the USA-NPN we have developed a new approach that directs observers to record each day that they observe an individual plant, and to assess and report the state of specific life stages (or phenophases) as occurring or not occurring on that plant for each observation date. Evaluation is phrased in terms of simple, easy-to-understand, questions (e.g. “Do you see open flowers?”), which makes it very appropriate for a citizen science audience. From this method, a rich dataset of phenological metrics can be extracted, including the duration of a phenophase (e.g. open flowers), the beginning and end points of a phenophase (e.g. traditional phenological events such as first flower and last flower), multiple distinct occurrences of phenophases within a single growing season (e.g multiple flowering events, common in drought-prone regions), as well as quantification of sampling frequency and observational uncertainties. These features greatly enhance the utility of the resulting data for statistical analyses addressing questions such as how phenological events vary in time and space, and in response to global change. This new protocol is an important step forward, and its widespread adoption will increase the scientific value of data collected by citizen scientists.
