Citizen science encourages people to participate in scientific research projects. One of the best-known initiatives is the City Nature Challenge contest, aimed at recording biodiversity in cities through the iNaturalist application. The metropolitan region of La Paz, Bolivia, participated in this contest in 2019 and 2022 under the name Reto Ciudad Naturaleza, thanks to the promotion of the Wildlife Conservation Society (WCS) Bolivia, the Biology Department and the Ecology Institute of Universidad Mayor de San Andrés (UMSA), and the National Museum of Natural History (MNHN), who formed an organizing committee. The objective was to strengthen the bond between the urban population and nature, with the aim to generate data on the knowledge and preservation of biodiversity. The activities consisted of the promotion and dissemination of the contest, training events regarding the use of iNaturalist, photographic records, taxonomic identification, and the delivery of certificates to participants. In 2019, La Paz competed with 158 cities and ranked eighth in number of species (3005), third in number of participants (1500), and second in number of observations (46 931). In 2022, 447 cities participated, and La Paz led in all three categories of the contest, with 137 345 observations, 5320 species, and 4296 participants. Beyond these results, the commitment of La Paz citizens to their biodiversity stands out, which results in an increasingly strong bond between the urban population and their natural environment.

La literatura sobre estructura productiva y crecimiento económico muestra la relevancia de la industria en la expansión del PIB en países desarrollados y en desarrollo. Estudios recientes indican que el sector de los servicios modernos (servicios profesionales) contribuye a la innovación, al aumento de la productividad y, en consecuencia, al crecimiento económico. Este artículo plantea una discusión teórica sobre la importancia del sector de los servicios modernos para América Latina a fin de actualizar la tesis central del enfoque estructuralista latinoamericano. Los datos indican que, aun en el contexto de una transformación productiva caracterizada por una menor participación de la manufactura y el auge del sector terciario, se perpetúa la división internacional del trabajo, sobre la base de la relación centro-periferia. Los resultados muestran que el pensamiento estructuralista resulta adecuado para explicar el persistente subdesarrollo de los países latinoamericanos desde una perspectiva centrada en la economía de servicios.

This article proposes an exploratory, panoramic and summary review of the main currents, models, and theories of literature that appear in the articles of the ninety-eight published issues of Revista Chilena de Literatura. This is a diachronic, descriptive, and critical study that follows a content analysis methodology set by Klaus Krippendorf’s model. The purpose of this model is to track and map these trends in order to give not only a global image of the state of the matter related to the literary theory and its participation in the formulation of the articles of the magazine, but also to set forth critical views on these approaches. This is a cross-sectional study of historical nature, which aims to link the articles to the various theoretical, critical and speculative traditions about literary studies developed in RChL.

Thyrotoxic periodic paralysis (TPP) is a fatal complication of thyrotoxicosis, characterized by sudden hypokalemia, muscle paralysis and thyrotoxicosis. TPP, although it is becoming more frequent in our country, is still not diagnosed in a timely manner due to the lack of familiarity and the subtlety of the referred symptomatology. Early recognition by the first contact physician can prevent the mortality of said disease. A typical case of thyrotoxic paralysis is presented in a private Mexican university hospital and a review of the most current literature is made. We conducted a review of the literature in PubMed and EMBASE. Clinical, biochemical, diagnostic, therapeutic and prognostic characteristics were analyzed. TPP is a clinical entity that occurs rarely in the Mexican population, however it is important to be familiar with the diagnosis since the treatment is different from other periodic hypokalemic paralysis.

El objetivo de este trabajo es evaluar los efectos de un conjunto de variables en la desigualdad de oportunidades en el Brasil. Para ello se utilizó el método desarrollado por Li, Chen y Gao (2011). Se combinaron datos de la Encuesta Nacional de Hogares (PNAD) y Finanzas de Brasil (Finbra) sobre los estados brasileños relativos al período comprendido entre 1995 y 2012. Los resultados indican que en los últimos años, el crecimiento económico ha perdido terreno en ese debate con respecto a los demás condicionantes. El patrón actual de los gastos en educación contribuye al mantenimiento de una situación de vulnerabilidad social que impide la plena integración de los individuos en la sociedad. Por otra parte, el aumento de la educación formal y de la formalización permitió una reducción de la desigualdad de oportunidades. [ABSTRACT FROM AUTHOR]

This article proposes a reading of the work by the chilean novelist Juan Agustín Palazuelos (1936-1969) considering, first, the different impressions of its critical reception. Therefore we intend to identified the strategies of Palazuelos's poetics that had defied, exceedd and frustrated the expectations of a meager group of critics. The multiplicity of his scriptural resources will be approached from the concept of disjecta membra, trough wich it is posible to establish links with the notions of monstrosity, excess, melancholy, spectacle, anamorphosis and simulation, among others.

Neocortical development in humans is characterized by an extended period of synaptic proliferation that peaks in mid-childhood, with subsequent pruning through early adulthood, as well as relatively delayed maturation of neuronal arborization in the prefrontal cortex compared with sensorimotor areas. In macaque monkeys, cortical synaptogenesis peaks during early infancy and developmental changes in synapse density and dendritic spines occur synchronously across cortical regions. Thus, relatively prolonged synapse and neuronal maturation in humans might contribute to enhancement of social learning during development and transmission of cultural practices, including language. However, because macaques, which share a last common ancestor with humans ∼25 million years ago, have served as the predominant comparative primate model in neurodevelopmental research, the paucity of data from more closely related great apes leaves unresolved when these evolutionary changes in the timing of cortical development became established in the human lineage. To address this question, we used immunohistochemistry, electron microscopy, and Golgi staining to characterize synaptic density and dendritic morphology of pyramidal neurons in primary somatosensory (area 3b), primary motor (area 4), prestriate visual (area 18), and prefrontal (area 10) cortices of developing chimpanzees (/Pan troglodytes/). We found that synaptogenesis occurs synchronously across cortical areas, with a peak of synapse density during the juvenile period (3-5 y). Moreover, similar to findings in humans, dendrites of prefrontal pyramidal neurons developed later than sensorimotor areas. These results suggest that evolutionary changes to neocortical development promoting greater neuronal plasticity early in postnatal life preceded the divergence of the human and chimpanzee lineages.

The aim of this article is to analyze situations in which it is intended to teach punctuation as a system of marks that offers guide to reader on how the text should be understood. Instead of conceiving punctuation's system as signs that reproduce intonation and pauses in oral language, punctuation is understood as a system that organizes the meaning of the text and, therefore, guides its interpretation. W e analyzed two situations developed at a third year in Basic education in which students read and write to produce an album of personal data. One situation refers to a discussion with all the class to correct a text written by others, invented ad hoc, which present problems with speaker's position, punctuation and unnecessary repetitions. Another situation consist in revision in pairs a text written by students who have got equivalent problems. [ABSTRACT FROM AUTHOR]

In this research we show the best efficient models in the evaluation of the recognition memory: First, a general mathematical model which underlies different data records ways. Second the election, organization and the presentation time of the stimulus is controlled experimentally. Third, we show the multilevel analysis for the rating scales, and a ROC and z-ROC distribution for the discrimination between TDS models and the threshold models. The results agree mainly with a TDS model when the stimuli are high frequency words, a model of threshold (or unequal-variance) when the stimuli are open class words, whereas the low frequency words occupy an intermediate place located between the TDS model and the threshold model.

We use a previously unexploited data set to calculate the real exchange rate with respect to the U.S. dollar for Mexico for 1930.01-1960.12, and to test for purchasing power parity (PPP). The initial results from the Augmented Dickey-Fuller (ADF) test show weak support for the PPP hypothesis. The Kapetanios, Shin, and Snell test, for a unit root null with an alternative of nonlinear reversion to the mean, indicates substantial support for PPP. However, non-normality and, sometimes, heteroscedasticity are found in the test residuals. Using a wild bootstrap approach, critical values are calculated from the empirical distribution of the residuals. Reevaluating the test statistics with the new critical values, we conclude that there is evidence of nonlinear adjustment to PPP for 1930.01-1951.12 but there is no evidence that PPP held for 1952.01-1960.12, the period of import substitution in Mexico.

A model of information ethics used to analyze intellectual property rights versus public access rights (Vaagan and Koehler, 2004/2005) is refined in two ways. First, the model is expanded to include new media which have become the primary information source for many in today's globalized information society (Webster, 2004; Lievrouw and Livingstone, 2006). Second, since freedom of expression is a primary concern for a majority of new media users worldwide (BBC, 2010), there is a need to incorporate freedom of expression in the model for it to retain explanatory value in the emerging system of "mass self communication" (Castells, 2009).

Cerrillos is an Early to Middle Paracas civic-ceremonial site located in the upper Ica Valley of Perú. The site is known for its finely plastered adobe architecture, beautifully decorated ceramics, and complex textiles, many of which are decorated with camelid hair. Cerrillos was located in a strategically important place where the mountains meet the coastal desert and the Ica River bends south, a likely intersection in a road system that connected Cerrillos to contemporary sites in the Paracas region and beyond. This paper focuses on several early textiles, ceramics, and other artifacts, including ceramic palettes used for gold working and wooden earspools, that suggest that Cerrillos was involved in a cultural phenomenon or interaction sphere that linked sites as far away was Chavín de Huántar through the interchange of goods, beliefs, and practices. The paper presents a complete description of the textiles excavated at Cerrillos between 1999 and 2002, focusing on two fabric fragments with images of the Staff Deity and one with an abstract Chavín-like design. The ceramics discussed in the text demonstrate the wide variety of styles found at Cerrillos, including some that resemble the Janabarriu of Chavín de Huántar and several others that are either not Paracas or an Early Paracas style that has never been previously described.

Este estudio examinó el patrón de condenas penales en individuos con esquizofrenia a lo largo de un período de 25 años, caracterizado por la desinstitucionalización generalizada y los índices crecientes de problemas relacionados con el consumo de sustancias en individuos con esquizofrenia residentes en la comunidad. Método: Para el período comprendido entre 1975 y 2000 se compararan los antecedentes penales de 2. 861 pacientes (de los cuales 1,689 eran de sexo masculino) que experimentaran un primer ingreso hospitalario por esquizofrenia en el estado australiano de Victoria los años 1975, 1980,1985,1990 y 1995 con los ingresos de idéntico numera de individuos de control comunitarios equiparados en edad, sexo y proximidad. Resultados: En comparación con los individuos de control, los pacientes con esquizofrenia acumularon un numero total de condenas penales superior (8. 791 frente a 1,119) y tenían una probabilidad significativamente mayor de haber sido condenados por un acto delictivo (21,6% frente a 7,8 %) y un delito acompañado de violencia (8,2 % frente a 1,8 %). El porcentaje de pacientes condenados aumentó del 14,8% de la cohorte de 1975 al 25,0% de la cohorte de 1995, observándose un aumento proporcional similar del 5,1 % al 9,6% en los individuos de control. El índice de problemas de abuso de sustancias confirmados aumentó en los pacientes con esquizofrenia desde el 8,3% de 1975 al 26,1% en 1995. Se constataron unos índices significativamente mayores de condenas penales en los pacientes con problemas de abuso de sustancias que en los pacientes que no presentaban problemas de abuso (68,1% frente a 11,7%). Conclusiones: Se demostró una relación significativa entre el padecimiento de esquizofrenia y un índice superior de condenas penales, especialmente para delitos acompañados de conductas violentas. El incremento del numero de condenas a lo largo del período de estudio de 25 años fue, sin embargo, similar entre los pacientes con esquizofrenia y los individuos de control, a pesar del cambio de un régimen fundamentalmente hospitalario a un régimen asistencial comunitario y del aumento drástico del numera de problemas relacionados con el abuso de sustancias en las personas con esquizofrenia. Los resultados no confirman las teorías que intentan atribuir la presencia de conductas delictivas en la esquizofrenia a un sólo factor, como el abusa de sustancias, la presencia de síntomas activos a las características de los sistemas asistenciales, sugiriendo más bien que las conductas delictivas son el resultado de diversos factores que entran en juego antes, durante y después de los períodos activos de la enfermedad.
