Who Do You Say That I Am? Christological Perspectives on Leadership in the Vincentian Tradition

Thomas Esselman explores who Jesus was for Vincent de Paul. He places Vincent’s christology within the context of the French school of spirituality, which countered the dogmatic theology of the day by keeping the experience of faith and of Jesus as its main concerns. As Esselman writes, “Vincent lived out of experience and out of the profound conviction that God’s presence could be found in time, events, and people. . . . He would not so much contemplate Jesus as see Jesus at work, strive to imitate him, and learn from this experience.” For Vincent, Jesus’s main work was being the evangelizer of the poor. The Congregation was to continue this while emulating his virtues and seeing him in all people, but especially in the poor. Vincent’s communities were to minister to the whole person, attending to physical and spiritual needs. Esselman explains how Vincent lived “the life of doxology,” seeing God in all experiences and loving the poor as God does. Esselman concludes with questions for reflection on how we incorporate Vincent’s vision of Jesus into our work

ISOMERIZATION BETWEEN CH2_2ClI AND CH2_2Cl-I IN CRYOGENIC MATRICES STUDIED ON ULTRAFAST TIMESCALE

Author Institution: The University of Wisconsin-Madison Department of Chemistry, 1101 University Avenue, Madison, WI, 53705; Department of Chemistry, Marquette University, Milwaukee, WI, 53233Photodissociation of species entrained in solid matrices potentially leads to reassociation of the newly formed fragments. After fixing CH$_2$ClI in various atomic and molecular matrices, we measure ultrafast transient absorptions to monitor the photolysis of the precursor and isomerization to form \emph{iso}-CH$_2$ClI. We probe the two lowest energy electronic absorption features of CH$_2$Cl-I near 435 nm and 800 nm. Probing the low energy side of the 435-nm band interrogates the formation and subsequent cooling of the hot, newly formed products. We find that the recoiling fragments, CH$_2$Cl and I, lose large amounts of energy to the environment in the initial collision with the matrix cage, which leads to formation of the isomer

Fish avoidance of ships during acoustic surveys tested with quiet uncrewed surface vessels

Acoustic surveys to estimate fish biomass and abundance are a major component of many fisheries monitoring programs. An important bias in acoustic surveys is that fish may avoid the survey vessel. Here, we utilized quiet uncrewed surface vessels (USVs) equipped with 120 kHz split beam echosounders to evaluate fish responses to motorized survey vessels. Two of these USVs were deployed in Lakes Michigan and Huron in summer 2021 and compared against three motorized vessels used in conventional fisheries acoustic surveys. Paired comparisons employed vessel-drone passes that provided the opportunity to observe fish response as vessels approached and then overtook their quiet USV counterparts. Sound originating from the vessels was primarily in the 10–1000 Hz range. Overall received sound pressure levels for ships at the closest pass were 100 dB (re 1 µPa @ 1 m) for one and 133–134 dB for the other two vessels. In contrast, sound originating from the USV was not detectable over ambient noise. We examined acoustic data from the USVs for potential changes in total acoustic backscatter, average target depth, and average in situ target strength as vessels approached. We observed weak evidence of an avoidance response by fish to the vessel with the loudest noise profile and highest survey speed but not for the other two vessels. We also compared acoustic data from 33 2-km transects surveyed by both vessels and the USVs, finding few differences between vessel and USV data for water depths between 5 and 80 m. Results from this work suggest that acoustics estimates of fishes in Lakes Michigan and Huron (primarily alewife, rainbow smelt, and bloater) are largely consistent among the vessels used in these two lakes for standard acoustic surveys and that fish avoidance is minimal in water depths \u3e 5 meters
