This chapter is devoted to tongue root (ATR or RTR) harmony in Tungusic languages (a.o. Classical Manchu) and Mongolian languages (Khalka and Buriat), which all belong the Altaic language group. In addition to TR-harmony, most Tungusic and Mongolian languages also have a limited form of labial harmony, especially among low vowels. After discussing the Tungusic and Mongolian systems the chapter will focus on the behavior of high vowels, which do not participate in labial harmony, and are either transparent or opaque. A notable difference between Tungusic and Mongolic regards the fact that whereas [i] is transparent to labial harmony in Mongolic, it is opaque in Tungusic. High round vowels are opaque in both groups.

This chapter provides a case analysis of the Catholic Church’s Synod on the Family, an assembly of bishops convened in Rome in October 2014 and October 2015, to address the changing nature of Catholics’ lived experiences of marriage and family life. The chapter argues that the Synod can be considered a postsecular event owing to its deft negotiation of the mutual relevance of doctrinal ideas and Catholic secular realities. It shows how its extensive pre-Synod empirical surveys of Catholics worldwide, its language-group dialogical structure, and the content and outcomes of its deliberations, by and large, met postsecular expectations, despite impediments posed by clericalism and doctrinal politics. The chapter traces the Synod’s deliberations, and shows how it managed to forge a more inclusive understanding of divorced and remarried Catholics, even as it reaffirmed Church teaching on marriage and also set aside a more inclusive recognition of same-sex relationships.

High Vowels

This chapter analyzes a number of vowel harmony systems which have been described or analyzed in terms of aperture (lowering or raising, including complete harmony). This takes us into areas where the literature on vowel harmony discusses cases involving the following binary features: [± high], [± low], [± ATR], and [± RTR]. Raising has been thought of as problematic for unary ‘IUA’ systems as these systems lack a common element for high vowels. This chapter suggests that raising can be attributed to ATR-harmony. The chapter also discusses typological generalizations and analyzes metaphony in Romance languages.

ABSTRACT The presence of Fe-oxidizing bacteria in the rhizosphere of four different species of wetland plants was investigated in a diverse wetland environment that had Fe(II) concentrations ranging from tens to hundreds of micromoles per liter and a pH range of 3.5 to 6.8. Enrichments for neutrophilic, putatively lithotrophic Fe-oxidizing bacteria were successful on roots from all four species; acidophilic Fe-oxidizing bacteria were enriched only on roots from plants whose root systems were exposed to soil solutions with a pH of <4. InSagittaria australis there was a positive correlation (P < 0.01) between cell numbers and the total amount of Fe present; the same correlation was not found for Leersia oryzoides. These results present the first evidence for culturable Fe-oxidizing bacteria associated with Fe-plaque in the rhizosphere.
