Critical rhetoric: Theory and praxis

Abstract: This essay sets forth a theoretical rationale for a critical rhetoric and presents eight “principles”; which, taken together, orient the critic toward the act of criticism The theoretical rationale encompasses two forms of critique, styled as a critique of domination and as a critique of freedom Both have in common an analysis of the discourse of power as it serves in the first case to maintain the privilege of the elite and, in the second, to maintain social relations across a broad spectrum of human activities The principles articulate an orientation that sees critique as a transformative practice rather than as a method, recognizes the materiality of discourse, reconceptualizes rhetoric as doxastic as contrasted to epistemic, and as nominalistic as contrasted to universalistic, captures rhetoric as “influential"as contrasted to “causal,”; recognizes the importance of absence as well as presence, perceives the potential for polysemic as opposed to monosemic interpretation, and as an activity that is

The last glacial termination.

Abstract: A major puzzle of paleoclimatology is why, after a long interval of cooling climate, each late Quaternary ice age ended with a relatively short warming leg called a termination. We here offer a comprehensive hypothesis of how Earth emerged from the last global ice age. A prerequisite was the growth of very large Northern Hemisphere ice sheets, whose subsequent collapse created stadial conditions that disrupted global patterns of ocean and atmospheric circulation. The Southern Hemisphere westerlies shifted poleward during each northern stadial, producing pulses of ocean upwelling and warming that together accounted for much of the termination in the Southern Ocean and Antarctica. Rising atmospheric CO2 during southern upwelling pulses augmented warming during the last termination in both polar hemispheres.

Phylogeny and classification of Rosaceae

Abstract: Phylogenetic relationships among 88 genera of Rosaceae were investigated using nucleotide sequence data from six nuclear (18S, gbssi1, gbssi2, ITS, pgip, and ppo) and four chloroplast (matK, ndhF, rbcL, and trnL-trnF) regions, separately and in various combinations, with parsimony and likelihood-based Bayesian approaches. The results were used to examine evolution of non-molecular characters and to develop a new phylogenetically based infrafamilial classification. As in previous molecular phylogenetic analyses of the family, we found strong support for monophyly of groups corresponding closely to many previously recognized tribes and subfamilies, but no previous classification was entirely supported, and relationships among the strongly supported clades were weakly resolved and/or conflicted between some data sets. We recognize three subfamilies in Rosaceae: Rosoideae, including Filipendula, Rubus, Rosa, and three tribes; Dryadoideae, comprising the four actinorhizal genera; and Spiraeoideae, comprising Lyonothamnus and seven tribes. All genera previously assigned to Amygdaloideae and Maloideae are included in Spiraeoideae. Three supertribes, one in Rosoideae and two in Spiraeoideae, are recognized.

Emotion regulation in children and adolescents.

Abstract: Within the past two decades, an "affect revolution" [Fischer and Tangney, Self-conscious Emotions: The Psychology of Shame, Guilt, Embarrassment, and Pride 1995:3-22] in research has revolutionized the ways in which emotion processes have been conceptualized and subsequently studied This review discusses the literature on emotion regulation (ER) in childhood and adolescence by first summarizing the trajectory of emotional development from infancy through adolescence, followed by a discussion of the biological and environmental influences on ER, and then a review of the literature linking ER to psychosocial functioning The penultimate section offers practical suggestions for identifying ER difficulties in children and strategies for intervention efforts Potential areas for future research conclude the review
