Since the beginnings of the Porfiriato, the intention to renew and insert the mainstream world trends in México were two of the most important characteristics, and with that trend of thought, a series of social expectations influenced by Europe were brought in. In that context the Reglamento de Teatro de la Ciudad de Mérida from 1878 was created, the content of which is analyzed in the present article, with the goal of understanding the role of citizen regulation through emotional control and the censorship of certain contents. To that effect, the methodology used to determine is the concept of civilization coined by Norbert Elias, which is an implement to recognize the motivation behind the speech embodied in the regulation. Ultimately it is possible to stablish a connection between what is said by Elias and the original purpose of the publication.  

In southern Mexico, midwifery has an important role in the maternal health care of women and families from different social strata. The present research was carried out in the cities of Felipe Carrillo Puerto and Tumben Kuxtal where I examined the construction of publics through midwifery. The analysis is based on two types of midwifery practices: autonomous midwives that offer their services in a tourist city and attract a multicultural, middle class and high (sensu Bourdieu); traditional midwives of Felipe Carrillo Puerto and help an indigenous public of more popular strata. The choice of midwifery by women from upper-middle class families is related to the social construction of taste. This public takes into account socially constructed characteristics such as the return to "the natural" for health care, respect for the decision of women on their bodies and representations of the ancestrality and indigenity of "the Mayan."

This Dossier, entitled, “ethnography of practices and institutions in the posmodern epoch”, is composed of four studies exploring processes of change in practices and institutions previously well defined and demarcated with qualifications like “modern” and “tradicional” but, now, embodied as hybrid or alternative. These practices and institutions studied in particular localities capture changes with continuities in cosmological orientations, gender and reproduction, kinship, and in the differentiation of publics; all reflecting much more global articulations. As such, they are an integral part of the anthropological thematic though cast in a critical epochal transition.

In this paper we reproduce some of the letters exchanged by Carlos Finlay and Crescencio Carrillo and Ancona in the year 1892 and where the latter provides historical and documentary data regarding the origin of yellow fever in pre-Hispanic America. Through voice recognition software, the letters were transcribed, converting them to a new digital format. The content of the original document allows us to verify that the information provided by Carrillo and Ancona reinforces Finlay’s hypothesis regarding the endemic nature of this disease and its persistence in the American continent since ancient times. An idea that contradicts that other that maintains that this pestilence had been brought by the Spaniards after their arrival in this continent.

Due to its geographic location and economic-cultural factors, photography had an early appearance in the state of Yucatan. These photographies, from the collection of the Guerra Studio, capture the Yucatecan society from the late nineteenth century and early twentieth century.

Pronothrotherium typicum is a late Miocene–early Pliocene (Huayquerian–Chapadmalalan SALMA) nothrotheriid sloth known from the Catamarca Province of northwestern Argentina. Pronothrotherium is one of four nothrotheriid genera known from relatively complete skeletal material, but unlike the other three, the osteology of Pronothrotherium has not been formally described. The present study provides the first detailed description and illustration of the cranial anatomy of Pronothrotherium, based largely on a nearly complete, subadult skull of P. typicum from the collections of The Field Museum (Chicago, Illinois, USA), as well as a less well-preserved adult skull and isolated mandible from the same collections. A revised cranial diagnosis of P. typicum is provided in the text. The skull of this species shows a number of distinctive features, most notably a peculiar vomerine keel in the nasopharynx, terminating in a swollen knob, that is, as far we know, a unique morphology among mammals. Based on the results of the present study, there appears to be reason to recognize two contemporaneous species of Pronothrotherium, P. typicum and P. mirabilis, although the latter is less well supported. We do not accept the validity of a third described species, P. figueirasi, considering it instead to be synonymous with P. mirabilis. The present study does not resolve the uncertain phylogenetic relationships among the well-preserved nothrotheriine taxa Pronothrotherium, Mionothropus (late Miocene), and the two Pleistocene genera in Nothrotheriini, Nothrotherium and Nothrotheriops. However, we hope that the data provided will facilitate subsequent phylogenetic studies that may resolve these issues.

The systematic study of spores and algal forms recovered from the Río Turbio Formation, middle–upper Eocene of the Austral Basin is presented. Freshwater algae, bryophytes, ferns and lycophytes are described. Closterium sp. cf. C. thailandicum Songtham et al., Botryococcus sp., Coelastrum sp. 1, Catinipollis geiseltalensis Krutzsch, Bryophyta s.l. sp. 1, Kuylisporites waterbolkii Potonié, Matonisporites sp. 1, Foveotriletes sp. 1, Polypodiisporites perverrucatus (Couper) Khan and Martin, Klukisporites scaberis (Cookson and Dettmann) Dettmann, Deltoidospora cf. australis, (Couper) Pocock, Verrucosisporites sp. 1, Verrucosisporites sp. 2 are new forms for the Río Turbio Formation. The species Crassoretitriletes vanraadshooveni Germeraad et al. is a new record for Argentina and Gleicheniidites circinidites Dettmann is a new record for the Eocene of Argentina.
