Detecting Detection: International Perspectives on the Uses of a Plot

One of the problems with books which are relatively general in nature is that many of the individual contributions tend to be so narrow and specialised that only the author has any knowledge of (or interest in) the issues under discussion. At first sight this appears to be the case with Detecting Detection. Fortunately, however, first impressions are deceiving. Although the essays in the volume deal with writers as diverse and disparate as the Catalano-Spanish writer Juan Marse, the Bulgarian-French philosopher Julia Kristeva and the once-vaunted giant of English literature,Graham Greene, among numerous others, there is much to be enjoyed and learnt, even if some of the works under discussion are unfamiliar to the crime fiction reader and/or scholar to whom the book initially appears to be directed.

Triggering the generation of an iron(IV)-oxo compound and its reactivity toward sulfides by RuII photocatalysis

The preparation of [FeIV(O)(MePy2tacn)]2+ (2, MePy2tacn = N-methyl-N,N-bis(2-picolyl)-1,4,7-triazacyclononane) by reaction of [FeII(MePy2tacn)(solvent)]2+ (1) and PhIO in CH3CN and its full characterization are described. This compound can also be prepared photochemically from its iron(II) precursor by irradiation at 447 nm in the presence of catalytic amounts of [Ru II(bpy)3]2+ as photosensitizer and a sacrificial electron acceptor (Na2S2O8). Remarkably, the rate of the reaction of the photochemically prepared compound 2 toward sulfides increases 150-fold under irradiation, and 2 is partially regenerated after the sulfide has been consumed; hence, the process can be repeated several times. The origin of this rate enhancement has been established by studying the reaction of chemically generated compound 2 with sulfides under different conditions, which demonstrated that both light and [Ru II(bpy)3]2+ are necessary for the observed increase in the reaction rate. A combination of nanosecond time-resolved absorption spectroscopy with laser pulse excitation and other mechanistic studies has led to the conclusion that an electron transfer mechanism is the most plausible explanation for the observed rate enhancement. According to this mechanism, the in-situ-generated [RuIII(bpy)3] 3+ oxidizes the sulfide to form the corresponding radical cation, which is eventually oxidized by 2 to the corresponding sulfoxide

Diversidad y Multiculturalidad

Esta ponencia se enmarca en la línea de anteriores trabajos nuestros, en los que se ha intentado ofrecer el panorama general de la investigación llevada a cabo en el campo de la diferenciación educativa, y, más en concreto de la educación intercultural. En «Diseños y metodologías de investigación desde la perspectiva de la educación intercultural » (Bartolomé, 1992), tras una breve clarificación de términos asociados a la educación multicultural, analizábamos los principales métodos de investigación y campos de estudio que se habían desarrollado a lo largo de este siglo en el ámbito mundial. En «Modelos de investigación en la intervención educativa diferencial» (Bartolomé, Cabrera, F., Espín, J., Marín, M.A., Del Rincón, D. y Rodríguez, M., 1993) nos centrábamos en un marco más amplio, intentando abordar el estado de la investigación en ese momento en cada una de las áreas temáticas, al tiempo que profundizábamos en los principales problemas metodológicos hallados.

Baixem de les tarimes i connectem: recerca en història medieval i innovació docent

We would like to introduce our group of research, [CONTRA TAEDIUM], created by professionals from different fields, that have contributed in this article. Our purpose is to expose our reflections based on our own experiences, not only in research, but also in teaching. We propose new forms of writing history in order to understand the dairy life of the women and men of the past, from birth to death. We would like to point out that interacting all types of sources is essential to understand our history. But, what really makes sense is to bring our students in the historical methodology and involve them in their education. Moreover, it is necessary to design new teaching materials using the new technologies, although it requires team-work and a great, but satisfying, effort
