La política agraria en Nuevo León durante el Maximato, 1928-1933

Durante el Maximato, período azotado por la crisis económica mundial, el Gobierno del Estado se encontraba orgulloso por el notable control que ejercía sobre las masas campesinas que veían cubiertas sus necesidades en forma parcial, al estar aglutinadas en una organización agraria ideada por un sistema paternalista y populista

Caída y exilio como motivos en El sueño del ángel, de Gloria Elena Espinoza

Se muestra que la novela El sueño del ángel, de la nicaragüense Gloria Elena Espinoza, se articula narrativamente alrededor de una serie de caídas, que afectan a los personajes. Son caídas que abarcan varios niveles: el natural, el antropológico, el axiológico y el divino; además, es una caída planteada desde una perspectiva milenarista y apocalíptica, que manifiesta una visión del mundo terrenal como corrupto y en decadencia. Se señala la condición del ángel caído (o exiliado) como una metáfora de la condición humana, asociada al desarraigo y a la derrota.It is shown how the Nicaraguan novel El sueño del ángel [The angel's dream] by Gloria Elena Espinoza is narrated around a series of falls affecting the characters. These falls span several levels: natural, anthropological, axiological and divine. The falls are also seen from a millenary and apocalyptical perspective, which sets forth a view of life on earth as corrupt and decadent. The condition of the fallen (or exiled) angel is explored as a metaphor for the human condition, related to alienation and defeat.

La conciencia de lo común frente a la falsa dicotomía estado-mercado. Análisis de la perspectiva de Elinor Ostrom (1933-2012)

Cada año que pasa desde que se le concediera el premio Nobel en 2009 a Elinor Ostrom por su trabajo en la gobernanza de los bienes comunes sus análisis cobran importancia y más notoriedad. El mundo que nos rodea está cambiando de forma rápida y constante, creando nuevos retos a nivel mundial. Los resultados de las investigaciones de Elinor Ostrom (1933-2012) han levantado expectativas sobre mecanismos alternativos para movernos hacia un entorno político, social, económico y natural renovado y más sostenible. En este trabajo se explora la perspectiva de esta pensadora respecto a cuestiones como la sostenibilidad de los recursos naturales, la organización social o la iniciativa individual dejando a un lado la dicotomía estado-mercado.

La política exterior expansionista y racista del Tercer Reich en Checoslovaquia y Croacia en 1933-1943

El objetivo de este estudio de caso es analizar la forma en la cual la política exterior expansionista y racista del Tercer Reich repercutió en la invasión militar de Checoslovaquia y en la creación de un régimen fascista en Croacia. El surgimiento del Tercer Reich implicó el desencadenamiento de la Segunda Guerra Mundial, generando un cambio en la configuración del Sistema Internacional. Desde el ascenso de Hitler al poder en 1933, Alemania proyectó una discursiva racista y expansionista en su política exterior, con el objetivo de configurar un nuevo ordenamiento europeo. Por lo anterior, la política exterior del Tercer Reich justificó la invasión de Checoslovaquia basándose en los principios del espacio vital que permitieron adherir el territorio al Reich, e influyó en el ascenso del régimen fascista de Ante Pavelić en Croacia, quien colaboró para la consecución del interés nacional racial alemán.

Respecting local, cultural contexts for assessment practice in an era of globalization

Dissatisfaction, internationally, with existing educational practices and outcomes since the early 1990s has led to increased educational reform. At the same time, there has also been a worldwide shift in control of education away from teachers toward the state for the purposes of restructuring economies. More bureaucratic forms of curriculum and assessment have resulted, with a return to the use of more techno-rational discourse in assessment and evaluation for purposes of efficiency, accountability, impact, and performance management. There has also been an increase in the use of economic and productivity models to study educational outcomes. These models fail to account for the range of outcomes achieved and fail to identify the factors responsible for such diversity in performance.

A visualisation framework for collaborative virtual environment usage information

Due to the popularity of modern Collaborative Virtual Environments, there has been a related increase in their size and complexity. Developers therefore need visualisations that expose usage patterns from logged data, to understand the structures and dynamics of these complex environments. This chapter presents a new framework for the process of visualising virtual environment usage data. Major components, such as an event model, designer task model and data acquisition infrastructure are described. Interface and implementation factors are also developed, along with example visualisation techniques that make use of the new task and event model. A case study is performed to illustrate a typical scenario for the framework, and its benefits to the environment development team.

Visualisation of Information Uncertainty : Progress and Challenges

Information uncertainty which is inherent in many real world applications brings more complexity to the visualisation problem. Despite the increasing number of research papers found in the literature, much more work is needed. The aims of this chapter are threefold: (1) to provide a comprehensive analysis of the requirements of visualisation of information uncertainty and their dimensions of complexity; (2) to review and assess current progress; and (3) to discuss remaining research challenges. We focus on four areas: information uncertainty modelling, visualisation techniques, management of information uncertainty modelling, propagation and visualisation, and the uptake of uncertainty visualisation in application domains.

Engaging students in programming

Poor student engagement and high failure rates in first year units were addressed at the Queensland University of Technology (QUT) with a course restructure involving a fresh approach to introducing programming. Students’ first taste of programming in the new course focused less on the language and syntax, and more on problem solving and design, and the role of programming in relation to other technologies they are likely to encounter in their studies. In effect, several technologies that have historically been compartmentalised and taught in isolation have been brought together as a breadth-first introduction to IT. Incorporating databases and Web development technologies into what used to be a purely programming unit gave students a very short introduction to each technology, with programming acting as the glue between each of them. As a result, students not only had a clearer understanding of the application of programming in the real world, but were able to determine their preference or otherwise for each of the technologies introduced, which will help them when the time comes for choosing a course major. Students engaged well in an intensely collaborative learning environment for this unit which was designed to both support the needs of students and meet industry expectations. Attrition from the unit was low, with computer laboratory practical attendance rates for the first time remaining high throughout semester, and the failure rate falling to a single figure percentage.

Green fireballs and ball lightning

This paper presents evidence of an apparent connection between ball lightning and a green fireball. On the evening of the 16th May 2006 at least three fireballs were seen by many people in the skies of Queensland, Australia. One of the fireballs was seen passing over the Great Divide about 120 km west of Brisbane, and soon after, a luminous green ball about 30 cm in diameter was seen rolling down the slope of the Great Divide. A detailed description given by a witness indicates that the phenomenon was probably a highly luminous form of ball lightning. An hypothesis presented in this paper is that the passage of the Queensland fireball meteor created an electrically conductive path between the ionosphere and ground, providing energy for the ball lightning phenomenon. A strong similarity is noted between the Queensland fireball and the Pasamonte fireball seen in New Mexico in 1933. Both meteors exhibit a twist in the tail that could be explained by hydrodynamic forces. The possibility that multiple sightings of fireballs across South East Queensland were produced owing to fragments from comet 73P Schwassmann-Wachmann 3 is discussed.

Functional role of cell surface CUB domain-containing protein 1 in tumour cell dissemination

The function of CUB domain-containing protein 1 (CDCP1), a recently described transmembrane protein expressed on the surface of hematopoietic stem cells and normal and malignant cells of different tissue origin, is not well defined. The contribution of CDCP1 to tumor metastasis was analyzed by using HeLa carcinoma cells overexpressing CDCP1 (HeLa-CDCP1) and a high-disseminating variant of prostate carcinoma PC-3 naturally expressing high levels of CDCP1 (PC3-hi/diss). CDCP1 expression rendered HeLa cells more aggressive in experimental metastasis in immunodeficient mice. Metastatic colonization by HeLa-CDCP1 was effectively inhibited with subtractive immunization-generated, CDCP1-specific monoclonal antibody (mAb) 41-2, suggesting that CDCP1 facilitates relatively late stages of the metastatic cascade. In the chick embryo model, time- and dose-dependent inhibition of HeLa-CDCP1 colonization by mAb 41-2 was analyzed quantitatively to determine when and where CDCP1 functions during metastasis. Quantitative PCR and immunohistochemical analyses indicated that CDCP1 facilitated tumor cell survival soon after vascular arrest. Live cell imaging showed that the function-blocking mechanism of mAb 41-2 involved enhancement of tumor cell apoptosis, confirmed by attenuation of mAb 41-2–mediated effects with the caspase inhibitor z-VAD-fmk. Under proapoptotic conditions in vitro, CDCP1 expression conferred HeLa-CDCP1 cells with resistance to doxorubicin-induced apoptosis, whereas ligation of CDCP1 with mAb 41-2 caused additional enhancement of the apoptotic response. The functional role of naturally expressed CDCP1 was shown by mAb 41-2–mediated inhibition of both experimental and spontaneous metastasis of PC3-hi/diss. These findings confirm that CDCP1 functions as an antiapoptotic molecule and indicate that during metastasis CDCP1 facilitates tumor cell survival likely during or soon after extravasation.
