Universidad y sociedad: la psicología aprendida mediante colaboraciones

Este material está dirigido tanto a investigadores como a profesores y estudiantes que tengan el interés de aprender nuevas formas de relacionarse para intervenir, en colaboración, en diferentes espacios sociales y realidades problemáticas. También puede resultar de interés para los directivos de instituciones públicas, privadas y organizaciones no gubernamentales que tengan a su cargo programas de intervención social, así como a luchadoras y luchadores sociales que busquen formas de organizarse para transformar situaciones particulares de vulnerabilidad. En estas páginas hay una invitación a formar universitarias y universitarios a partir de su intervención en problemáticas y escenarios vivos, a reconocer el saber colectivo de los otros que están insertos en diferentes situaciones y aprender que el conocimiento se genera a partir del vínculo y la colaboración con la diversidad.ITESO.

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Strategies and performance of the CMS silicon tracker alignment during LHC Run 2

The strategies for and the performance of the CMS silicon tracking system alignment during the 2015–2018 data-taking period of the LHC are described. The alignment procedures during and after data taking are explained. Alignment scenarios are also derived for use in the simulation of the detector response. Systematic effects, related to intrinsic symmetries of the alignment task or to external constraints, are discussed and illustrated for different scenarios
