Journey Into Shame: Implications for Justice Pedagogies
No full textBeing formed for justice can be a painful experience. Sometimes that pain takes the form of shame and contributes to the formation and exercise of conscience. But shame in other forms can be opposed to human flourishing and social justice. Psychologist James Fowler provides a spectrum of two forms of healthy shame and four forms of unhealthy shame, to which the author adds four other varieties, strategic shame and spiritual shame, at one end of the spectrum, and murderous shame and genocidal shame, at the other. Various experiences of shame are dramatically illustrated in Black Like Me, John Howard Griffin’s classic narrative of racism in the Deep South. It is crucial for social justice educators to be able to discern among these forms of shame in their own experience and when reported by students, so that healthy forms can be sympathetically honored and unhealthy forms critically examined
Eruptive hummocks: Building blocks of the upper ocean crust
No full textThe spreading axis at many slow-spreading mid-ocean ridges is marked by an axial volcanic ridge. In this study, we use a combination of high-resolution remote sensing methods to elucidate the detailed nature of volcanoes in such a ridge. We find that the “hummocks” described in previous sidescan sonar studies are dome- or cone-shaped edifices, 5–150 m high with diameters of 30–330 m. We estimate they form quickly, in single eruptions, each of which may produce several hummocks. Hummock collapse is common and hummocks of all heights are prone to failure. Collapses generally occur down the regional seafloor slope, suggesting control by local topography. Approximately 33% of hummocks lose ?40% of their volume by collapse, so ?12% of all material erupted on the axial volcanic ridge is rapidly converted to talus. The higher porosity of these deposits may increase average upper crustal porosity by several percent, contributing >0.5 km s?1 to seismic velocity decrease in the upper oceanic crust, and may be one of the dominant mechanisms for increasing porosity in upper slow-spreading oceanic crust

"Third Generation"-Type Functional Tris(2-pyridyl)borate Ligands and their Transition-Metal Complexes
No full textPhenyltris(2-pyridyl)borates (Tpyb) are a promising class of tripodal “scorpionate”-type ligands with potential utility in the development of transition metal complexes with interesting optical, electronic or magnetic properties, and as building blocks to metallosupramolecular polymers. We report here a new class of “third generation”-type Tpyb ligands that contain different functional groups attached to the boron-bound aryl moiety. The synthesis, characterization and metal ion complexation behavior of ligands with iodo and trimethylsilyl groups is discussed. The electrochemical and absorption characteristics of the corresponding low-spin Fe(II) and Ru(II) complexes are compared. We demonstrate the further elaboration of the iodo derivatives with alkynes via Sonogashira-Hagihara coupling, a process that proceeds with high yield for the Fe(II) and Ru(II) complexes, but not for the free ligand. The borylation of the silyl-substituted Ru(II) complex with BBr3 was also investigated. In addition to the expected borylation product, Ru(Tpyb-Bpin)2, the replacement of one (major product) or two phenyl groups is observed, suggesting that electrophilic borylation occurs at both the C(Ph)-Si and the C(Ph)-B aromatic carbons. The successful attachment of a range of different functional groups at the periphery of the Tpyb metal complexes is expected to provide opportunities to access new polymeric materials via C-C coupling or click-type reactions.Peer reviewe
