No full textThis article focuses on new research conducted by various scholars in the field of language teaching from a diachronic perspective. The collected volume "Texts and ideas in the history of
language learning and teaching" brings together peer-reviewed contributions that analyze
an array of textual genres spanning diverse historical periods, countries
and cultures, and encompass various languages. The texts reflect the
evolving landscape of ideas and socio-historical paradigms pivotal to
language teaching and learning. Ranging from the 16th to the 20th century, these contributions employ diverse methodological perspectives,
with a common denominator being the historiographical slant. The
authors delve into questions such as: how – and why – were pedagogical
texts compiled across diverse countries and periods? How can these
texts be analyzed linguistically? How have other textual genres – general
and specialized press, literary texts, travel books, etc. – contributed to
enhancing the debate on foreign language teaching? How do these texts
relate to the socio-political and historical context(s)

Higher-order effects in bandwidth-limited soliton propagation in optical fibers
No full textBy means of numerical studies and soliton perturbation theory we examine the effects of higher-order linear and nonlinear terms in bandwidth-limited amplified soliton propagation. We show that these effects are responsible for strong reductions of soliton-soliton interaction in such systems
