This article asserts that the particularly personal nature of Lutheran preaching compels preachers to be personally present with the words they proclaim and the people in front of them as they give them the gift of the gospel. Lutheran preaching prioritizes and drives toward the explicit proclamation of Christ crucified that declares Christ's promises to be true "for you." This is personal. The gospel is proclaimed not in general for all, but for each. The preacher gives the gospel to the people in front of them, just as the bread and cup are given to the people in Holy Communion. Such an intimate task invites an intimate presence. After unpacking the term "personally present," this essay outlines three interrelated elements of Lutheran preaching that reveal the importance of the presence of the preacher, and a few words are offered to suggest ways in which these learnings may be of interest to those of other traditions. Finally, four exercises are provided to help homileticians foster this presence in their students and to assist preachers in fostering this presence during their preaching preparation.

In addition to its role in substrate selection (carbohydrate vs. fat) for oxidative metabolism in muscle, acetylcarnitine production may be an important modulator of the energetic pathway by which ATP is produced. A combination of noninvasive magnetic resonance spectroscopy measures of cytosolic acetylcarnitine and ATP production pathways was used to investigate the link between [acetylcarnitine] and energy production in vivo. Intracellular metabolites were measured in the vastus lateralis muscle of eight males (mean: 28.4 yr, range: 25-35) during 8 min of incremental, dynamic contractions (0.5 Hz, 2-min stages at 6%, 9%, 12%, and 15% maximal torque) that increased [acetylcarnitine] approximately fivefold from resting levels. ATP production via oxidative phosphorylation, glycolysis, and the creatine kinase reaction was calculated based on phosphorus metabolites and pH. Spearman rank correlations indicated that postcontraction [acetylcarnitine] was positively associated with both absolute (mM) and relative (% total ATP) glycolytic ATP production (rs = 0.95, P = 0.001; rs = 0.93, P = 0.002), and negatively associated with relative (ss = 0.81, P = 0.02) but not absolute (rs = 0.14, P = 0.75) oxidative ATP production. Thus, acetylcarnitine accumulated more when there was a greater reliance on "nonoxidative" glycolysis and a relatively lower contribution from oxidative phosphorylation, reflecting the fate of pyruvate in working skeletal muscle. Furthermore, these data indicate striking interindividual variation in responses to the energy demand of submaximal contractions. Overall, the results of this preliminary study provide novel evidence of the coupling in vivo between ATP production pathways and the carnitine system. NEW & NOTEWORTHY Production of acetylcarnitine from acetyl-CoA and free carnitine may be important for energy pathway regulation in contracting skeletal muscle. Noninvasive magnetic resonance spectroscopy was used to investigate the link between acetylcarnitine and energy production in the vastus lateralis muscle during dynamic contractions (n = 8 individuals). A positive correlation between acetylcarnitine accumulation and "nonoxidative" glycolysis and an inverse relationship with oxidative phosphorylation, provides novel evidence of the coupling between ATP production and the carnitine system in vivo.

This multi-authored article investigates how institutions theorize themselves through the pervasive cultural construct of the pioneer. Examples from Denver and Colorado are emphasized. Further problematizing the myth building and legitimization of authority of institutions of higher education within the settler state by unpacking the concept settler colonialism, the authors recognize it as a persisting structure rather than as a historic event. Through this, the contemporary practice of settler land acknowledgement is analyzed and interrogated within the context of both historical and continuous pioneer violence; next steps for land acknowledgements are then framed by Eve Tuck's desire-based research model.
