Saddlebags, City Streets and Cyberspace: A History of Preaching in the Churches of Christ

This innovative book traces the history of preaching in the Stone-Campbell tradition, seeing how styles of rhetoric emerged and blended together. It traces the development of debaters, peacemakers, evangelists, and the influence of media on preaching (radio, television, and internet). This book by Mike Casey is pioneering scholarship. . . Whether or not one agrees with Mike, I predict that any future studies on preaching in our movement will, of necessity, commence with this book. —Thomas Olbrichthttps://digitalcommons.acu.edu/acu_library_books/1022/thumbnail.jp

Aid and Assistance as a “Use of Force” Under the Jus Ad Bellum

Although the prohibition of the use of force is a cornerstone of international law, our understanding of what constitutes a “use of force” under Article 2(4) of the UN Charter nonetheless continues to evolve. While the term was traditionally understood to mean armed force, emerging interpretations are expanding our understanding of the prohibition’s breadth. The Charter’s text, travaux préparatoires, and subsequent interpretations and practice by States, reinforced by the persuasive reasoning of the International Court of Justice, all confirm that the notion of force extends to indirect force, which includes military support provided to parties to a conflict. Yet, to date, States have failed to meaningfully contend with the notion of indirect force, much less clarify its precise threshold. Accordingly, through the lens of the Russia-Ukraine conflict, this article examines whether and, if so, when a State\u27s military aid or assistance that contributes to another State\u27s use of force constitutes a separate and distinct use of force under international law. After concluding that aid or assistance can, under certain conditions, qualify as a use of force, the article proposes several non-exclusive factors that States are likely to consider when assessing whether aid or assistance from a supporting State crosses the prohibition’s threshold

Prisoner of War Status and Nationals of a Detaining Power

This article examines whether a Detaining State is obliged to recognize prisoner of war status for its own nationals under Article 4A of the 1949 Geneva Convention III. It begins with an assessment of that article from the perspective of established principles for construing treaty provisions. It then adds context to that assessment by examining relevant scholarship and State practice regarding its prescriptions before and after the Convention’s negotiation and adoption. Although it concludes that denying prisoner of war status to a national of the Detaining Power is the more persuasive interpretation of Article 4A, it concludes by highlighting the practical challenges of determining nationality that Detaining States may confront

Comparison of Two Zooplankton Sampling Gears in Shallow, Homogeneous Lakes

We compared two zooplankton collection gears, Wisconsin nets and column samplers, to evaluate the effectiveness of each gear in quantifying inshore and offshore zooplankton density and size structure in shallow, homogeneous lakes. Zooplankton densities (within gear) did not differ (P \u3e 0.05) between inshore and offshore sites in either study lake, with the exception of Wisconsin-netted Cyclops sp. in Lake Goldsmith. Wisconsin net samples produced a higher mean zooplankton density than column samplers for Bosmina sp., Cyclops sp., and Daphnia sp. in East Oakwood Lake and for Cyclops sp. (inshore), Daphnia sp., and Diaptomus sp. in Lake Goldsmith. Zooplankton densities had greater variability (coefficients of variation) in 4 of 5 taxa collected with the Wisconsin net in both study lakes. Zooplankton size structure did not differ (P\u3e 0.05) between gears in either study lake, with the exception of Diaptomus sp. in East Oakwood Lake. Our results suggest that column samplers have higher precision than Wisconsin nets when sampling common zooplankton species in shallow, homogeneous lakes

Femoral loading mechanics in the Virginia opossum (Didelphis virginiana): torsion and mediolateral bending in mammalian locomotion

Studies of limb bone loading in terrestrial mammals have typically found anteroposterior bending to be the primary loading regime, with torsion contributing minimally. However, previous studies have focused on large, cursorial eutherian species in which the limbs are held essentially upright. Recent in vivo strain data from the Virginia opossum (Didelphis virginiana), a marsupial that uses a crouched rather than an upright limb posture, have indicated that its femur experiences appreciable torsion during locomotion as well as strong mediolateral bending. The elevated femoral torsion and strong mediolateral bending observed in D. virginiana might result from external forces such as a medial inclination of the ground reaction force (GRF), internal forces deriving from a crouched limb posture, or a combination of these factors. To evaluate the mechanism underlying the loading regime of opossum femora, we filmed D. virginiana running over a force platform, allowing us to measure the magnitude of the GRF and its three-dimensional orientation relative to the limb, facilitating estimates of limb bone stresses. This three-dimensional analysis also allows evaluations of muscular forces, particularly those of hip adductor muscles, in the appropriate anatomical plane to a greater degree than previous two-dimensional analyses. At peak GRF and stress magnitudes, the GRF is oriented nearly vertically, inducing a strong abductor moment at the hip that is countered by adductor muscles on the medial aspect of the femur that place this surface in compression and induce mediolateral bending, corroborating and explaining loading patterns that were identified in strain analyses. The crouched orientation of the femur during stance in opossums also contributes to levels of femoral torsion as high as those seen in many reptilian taxa. Femoral safety factors were as high as those of non-avian reptiles and greater than those of upright, cursorial mammals, primarily because the load magnitudes experienced by opossums are lower than those of most mammals. Thus, the evolutionary transition from crouched to upright posture in mammalian ancestors may have been accompanied by an increas

Principles of genome evolution in the Drosophila melanogaster species group.

That closely related species often differ by chromosomal inversions was discovered by Sturtevant and Plunkett in 1926. Our knowledge of how these inversions originate is still very limited, although a prevailing view is that they are facilitated by ectopic recombination events between inverted repetitive sequences. The availability of genome sequences of related species now allows us to study in detail the mechanisms that generate interspecific inversions. We have analyzed the breakpoint regions of the 29 inversions that differentiate the chromosomes of Drosophila melanogaster and two closely related species, D. simulans and D. yakuba, and reconstructed the molecular events that underlie their origin. Experimental and computational analysis revealed that the breakpoint regions of 59% of the inversions (17/29) are associated with inverted duplications of genes or other nonrepetitive sequences. In only two cases do we find evidence for inverted repetitive sequences in inversion breakpoints. We propose that the presence of inverted duplications associated with inversion breakpoint regions is the result of staggered breaks, either isochromatid or chromatid, and that this, rather than ectopic exchange between inverted repetitive sequences, is the prevalent mechanism for the generation of inversions in the melanogaster species group. Outgroup analysis also revealed evidence for widespread breakpoint recycling. Lastly, we have found that expression domains in D. melanogaster may be disrupted in D. yakuba, bringing into question their potential adaptive significance
