We present an analysis of how prospective mathematics teachers identify their own arguments to solve a geometric conjecture problem. This analysis, based on our conceptual proposal of argument, resulted in an emergent coding that revealed diverse meanings of argument. These are differentiated by their communicative intent, which includes description, narration and enunciation of conjectures or rules of mathematical work. The results indicate that practices such as recognising the nature of an argument, identifying its constituent elements and establishing functional relationships between arguments require specialised training even in learning environments that promote argumentation.

Background and objective. Lip and nose symmetry are the goal of repair of unilateral cleft lip and different pre and postoperative treatments have been developed with this purpose. The objective of this study was to perform a review of the literature to evaluate the effects of postoperative nasal conformers on cleft lip and palate patients. Methods. We conduct a systematic review of the literature for studies published until March 2021 to evaluate aesthetic effect using nasal conformers after primary cheilorhinoplasty in patients with cleft lip and palate. Results. We identified 6 studies for the final analysis, which included 195 patients. The overall study quality according to Oxford CEBM and Newcastle-Ottawa scale was low. Conclusions. The results obtained from this study provides that placement of postoperative nasal conformers did not improve nasal symmetry in patients with unilateral cleft lip and palate. Based on available scientific evidence, definitive conclusions about the effectiveness of these devices on nasal symmetry after unilateral cleft lip nose repair cannot be drawn.

The article discusses the role of the National Museum of Colombia in rewriting the country's history on various themes like diversity, violence, minorities, and reconciliation. Topics include the challenge before the museum in tracing Colombia's recent history of violence while its main protagonists are still alive; and the role of the museum's curators and specialists in encouraging new reflections on citizenship by including narratives of the violence of the 1980s, 90s, and early 2000s.

During the twentieth century, democracy became a central concept when grounding and legitimizing political action. The Chilean Marxist Left was not alien to this phenomenon. Based on periodical, doctrinal journals, memoirs and public discourses, in this article we study the political and conceptual trajectories of democracy in the doctrinal and strategic elaboration of the main left-wing parties and movements between the 1950s and the 1980s. In that period, democracy and revolution became conceptually decoupled. While the conflictive construction and application of a transition project to socialism incorporated the democratic ideal, the 1973 defeat forced a general restructuring, marked by the choice to reconstruct a representative democracy rather than aspire to revolutionize social structuress.

An interpretive research study is presented. Through a nonstructured interview, semiotically mediated by the interviewer, we track the personal meaning making process that a 7th grade student carries out with respect to a specific geometric fact. The analysis, presented through vignettes, is done from a semiotic perspective, based on Peirce's triadic sign theory. We evidence that when introducing a student to activity of scientific nature an expert's semiotic mediation can notably benefit the student, particularly, to clarify, relate and express his ideas.

This article seeks to illuminate the complexity and diversity of the theoretical and practical transformations experienced by political parties of the left after the coup d'état of 1973. The analysis is made addressing the historical trajectory of the socialist party, its link with the communist party and the issue of exile as an influential factor in the different types of political renovation. [ABSTRACT FROM AUTHOR]

The objective of this article is to contribute to academic reflection on the relevance of exile in Europe to the Chilean left's political renewal and its effect on the transition to democracy. Specifically, it will focus on the process of Socialist Renewal and how the situation in the Netherlands impacted that reflection. In this way, the political reasons for the Netherlands' support of the democratic struggle for the Chilean political community, through the founding of the Institute for a New Chile, will be analyzed. This institute was key in the process of debate and circulation of the political transference contained in Renewal in exile and connected the discussions carried out in Chile. The investigation included access to the Fund of the Socialist International Archives of the Institute of Social History in Amsterdam, the Countries Fund in Chile's Ministry of Foreign Affairs' Archive and Saskia Stuiveling's personal archives, as well as interviews with key informants.

This paper examines the creation of the Colombian Indigenista Institute, CII (1942), its institutional history, and its closure (1949). The CII, influenced by the Mexican indigenista movement, fought for indigenous peoples’ visibility for eight years. In the end, however, the CII failed due to a combination of internal factors such as ideological disagreements, and internal ones, including violence, scarce resources, and lack of awareness on the part of politicians and elites about the status, challenges, and even existence of Amerindian groups in Colombia. Three Colombian scholars created the CII. They attended the First Inter-American Indigenista Congress (Pátzcuaro 1940) where they got in touch with Manuel Gamio, then director of the Interamerican Indigenista Institute. Gamio´s ideas — that Indians have the right to govern themselves, to have tribal organizations, to elect their community leaders, and to maintain and assert their cultural identity — inspired the Colombians. In this paper, I trace the influences of the Mexican indigenista movement on Colombian indigenismo projects between 1940 and 1950. I draw on a variety of sources including Colombian newspapers and magazines, as well as letters of the indigenistas housed at the Colombian library Luis Ángel Arango in Bogotá and the Nettie Lee Benson Latin American Collection at the University of Texas at Austin. I conclude by explaining why Colombian indigenismo of the decade between 1940 and 1950 ultimately failed. [ABSTRACT FROM AUTHOR]

The purpose of this study is to compare the results of the surgical treatment of cleft palate obtained using 2 different protocols. We conduct a retrospective study comparing a protocol A, using one surgical technique to address all cleft types, and a protocol B, using different surgical techniques according to our proposed classification, and determining the number of fistulas and velopharyngeal insufficiency obtained using each protocol. We have seen statistically significant differences in the number of palatal fistulas between the two protocols, on behalf of protocol B (p: 0.0001). We have not seen statistically significant differences in the number of velopharyngeal insufficiency cases between the two protocols (p: 0.64) In summary, we observed less number of fistulas using the individualized protocol (protocol B) in the surgical treatment of cleft palates showing the efficacy of the proposed classification and used techniques. These conclusions support our proposal in this article with the new classification and individualized surgical protocol. [ABSTRACT FROM AUTHOR]

We present our experience using the Kirschbaum's flap (in charretera) for reconstruction of scar retractions of the neck and face. This is a retrospective study of a series of 63 patients with burn scar contracture of the anterior portion of the neck and facial lower third, operated by the author between 1996 and 2012 in the context of the surgical campaigns developed around the country (Peru) in those geographic areas of greatest need for specialized medical attention. We use in all patients the "charretera" flap, raised from the lateral portion of the neck and the deltoid area. Patients were evaluated by physical exam and using pre and postoperative photos. We obtained improvement of the functional limitation of the neck and face areas in different degrees in all the operated cases, with total survival of the flap in 59 cases (93.65 %) and partial survival in 4 cases (6.34 %). We have no cases of total necrosis. The complication rate was low, mainly hematomas, 6 cases (52 %) and infection, 2 cases (3.17 %). The donor sites suffered hypertrophic scars in 22 cases (34.92 %). In conclusion, our experience using this surgical technique has proven useful in the treatment of burn sequels with scar retraction of the neck and face, so we considered that Kirschbaum's flap is a safe method with low rate of complications.

The cleft lip deformities present in a wide spectrum of variation and their treatment requires a very detail description of the morphology and a more individualized surgical treatment. Most of reference center around the world use one surgical technique or modifications of it, to address the different forms of cleft lip. During our first years of experience we repair all the cleft forms using only one technique (Millard for unilateral and Mulliken for bilateral) with good and bad results. This scenario stimulates us to classify the cleft lips and propose a new strategy for their surgical treatment, making them more individualized. The purpose of this study is to compare the surgical results obtained using two different protocols. This is an analytic and comparative study of 2 protocols: protocol A, using one surgical technique to address all cleft types, and protocol and B, using different surgical techniques according to our proposed classification based on number of bad results obtained using each one. To establish the type of result obtained we did anthropometric measurements in both sides of the repaired lip before the cleft palate repair under general anesthesia. In both cases, we have seen statistically significant differences in the number of bad results between the two protocols, on behalf of protocol B (p: 0.0001 and p: 0.002). We observed less number of bad results using the individualized protocol (protocol B) in the surgical treatment of unilateral and bilateral cleft lip showing the efficacy of the proposed classification and used techniques. These conclusions support our proposal in this article, with the new classification and surgical techniques. [ABSTRACT FROM AUTHOR]

This article explores the narrative capacity of the chronicle and recognizes its intrinsic ability to tell time, that is, to account for time, and to give to humanity a certificate of existence. The chronicle, as a hybrid genre, is capable of showing life through narrative, and this has been the case for centuries. An example is the conquest of the Americas and the role of the writer of chronicles in showing the monarch what there was to see in the new world, so the latter could take possession, in his imagination, of the territories. But the chronicle didn't stop there. It migrated, according to Walter Mignolo, to other disciplines; to literature and to journalism. And it is relevant to this day in the works of those who work on the plane that doesn't distinguish reality from fiction. The chronicle is alive and will continue to be a narrative vehicle that saves lives. [ABSTRACT FROM AUTHOR]

In response to Fredric Jameson's argument, this conference argues that the peculiarity of the historical novel has been to elude any stable stratification of high and low. Its evolution exhibits rather an oscillating continuum of registers, and it's the extent of this continuum that arguably sets it apart from other narrative forms. The text also investigates the reasons why the historical novel, nowadays, is widespread among the superior levels of fiction, even more than during its classical period, the first decades of the XIXth century.
