A pesar de la abundante historiografía sobre la Unidad Popular, esta ha sido abordada principalmente desde la óptica de la historia política y de las relaciones internacionales. Existen relativamente ...pocos trabajos que se hayan aproximado a la llamada “vía chilena al socialismo” desde la historia cultural. Una historia social de las representaciones y prácticas culturales de ese periodo crucial de la Guerra Fría en América Latina permitiría estudiar con más profundidad cuestiones tales como la democratización de las instituciones culturales durante el gobierno de Allende, las iniciativas culturales y artísticas militantes surgidas entre los grupos que lo apoyaban, las numerosos relaciones culturales transnacionales que se desarrollaron en esa época y el rol jugado por los medios de comunicación masiva.
Background : In humans, the adrenal glands and gonads undergo distinct biological events between 6-10 weeks post conception (wpc), such as testis determination, the onset of steroidogenesis and ...primordial germ cell development. However, relatively little is currently known about the genetic mechanisms underlying these processes. We therefore aimed to generate a detailed genomic atlas of adrenal and gonad development across these critical stages of human embryonic and fetal development. Methods : RNA was extracted from 53 tissue samples between 6-10 wpc (adrenal, testis, ovary and control). Affymetrix array analysis was performed and differential gene expression was analysed using Bioconductor. A mathematical model was constructed to investigate time-series changes across the dataset. Pathway analysis was performed using ClueGo and cellular localisation of novel factors confirmed using immunohistochemistry. Results : Using this approach, we have identified novel components of adrenal development (e.g. ASB4 , NPR3 ) and confirmed the role of SRY as the main human testis-determining gene. By mathematical modelling time-series data we have found new genes up-regulated with SOX9 in the testis (e.g. CITED1 ), which may represent components of the testis development pathway. We have shown that testicular steroidogenesis has a distinct onset at around 8 wpc and identified potential novel components in adrenal and testicular steroidogenesis (e.g. MGARP , FOXO4 , MAP3K15 , GRAMD1B , RMND2 ), as well as testis biomarkers (e.g. SCUBE1 ). We have also shown that the developing human ovary expresses distinct subsets of genes (e.g. OR10G9 , OR4D5 ), but enrichment for established biological pathways is limited. Conclusion : This genomic atlas is revealing important novel aspects of human development and new candidate genes for adrenal and reproductive disorders.
Purpose
The aim of this paper is to determine whether the effort invested by service companies in employee training has an impact on their economic performance.
Design/methodology/approach
The study ...centres on an intensive labor sector, where the perception of service quality depends on who renders this service. To overcome the habitual problems of transversal studies, the time effect has been considered by measuring data over a period of nine years, to give panel data treatment with fixed effects.
Findings
The prepared models give clear empirical support to the hypothesis that training activities are a positive influence on company performance.
Research limitations/implications
The results obtained contribute empirical evidence about a relationship that, hitherto, has not been satisfactorily demonstrated. However, there may be some limitations related to the use of a training indicator based on effort and not on results obtained, with low representation of what happens in the smaller companies that lack structured training policies, or with no differentiation between generic or more specific training.
Practical implications
The results obtained can contribute towards increased manager awareness that training should be treated as an investment and not considered as an expense.
Originality/value
The main contributions can be resumed in three points: a training measurement has been used, based on three dimensions, which presumes to be an improvement on the more frequent method of measuring this variable. A consistent methodology was used that previously was not applied in the analysis of this relationship, and clear empirical evidence has been obtained concerning a relationship that, frequently, is mentioned with theoretical arguments, but which needs more empirical evidence.

The cinema is one of the foremost artistic and cultural media of the 20th and 21st centuries. It is also a powerful tool for mass communication. These factors have made it a primary source of great ...interest in the study of developments both in the political sphere and the collective imagination of given communities at specific historical periods. Hence the considerable number of researchers who have paid close attention to the relationship between cinema and history. One aim of this “Cinema a...
Purpose This paper aims to narrow the gap caused by the lack of literature relating the three concepts of corporate sustainability, organizational resilience and corporate purpose in the context of ...corporations. A framework that explains how these three concepts are related and effectively merged for long-term corporate survival are proposed. Design/methodology/approach A systematic review is carried out. It is explained, first, initial search strategies to identify those documents that define each concept and to identify concepts with which each concept is associated. Subsequently, it is designed a search strategy combining all three concepts and their associated concepts to gather and analyze all the possible studies that have tried to connect these concepts. Finally, it is identified some gaps in the understanding of how these three concepts are related. Findings Results indicate that corporate sustainability, organizational resilience and corporate purpose merge to achieve long-term corporate survival. There exists a two-way relationship between these three variables. Findings also present gaps and future directions that should be addressed to foster an increase in knowledge about the relationships between corporate sustainability, organizational resilience and corporate purpose. Originality/value Nowadays, some authors endeavor to explain how aspects such as corporate sustainability, organizational resilience and corporate purpose are crucial in the dynamic environment facing corporations every day. Nevertheless, there needs to be more understanding of how these three concepts are related and effectively merged for long-term corporate survival. This paper contributes to the literature by closing this gap.
No início dos anos 1960 ganha força na Argentina uma reinterpretação do movimento peronista realizada desde a esquerda. As novas tendências peronistas fazem uma “reconstrução retrospectiva” do ...justicialismo, ao qual atribuem características revolucionárias que o inserem entre os movimentos de libertação do Terceiro Mundo. Neste artigo, analisa-se como o coletivo de realizadores Grupo Cine Liberación construiu nos filmes La hora de los hornos (1968) e Los hijos de Fierro (1975) uma memória da resistência das bases peronistas durante os anos 1960 e 1970, que se inscreve dentro do peronismo revolucionário. No primeiro filme, recorre-se a material de arquivo e a entrevistas de militantes para edificar uma memória onde se destaca a unidade do movimento. No segundo, por outro lado, a referida memória se elabora de forma metafórica, a partir de uma adaptação e atualização do poema Martín Fierro (José Hernández, 1872-1879). Embora os dois longas-metragens coloquem ênfase no relato da resistência peronista, La hora de los hornos desemboca em um chamado à ação armada e em uma sacralização da figura do guerrilheiro, cujas características de sacrifício e martírio são destacadas. No entanto, em Los hijos de Fierro – concluído após a morte de Perón e realizado em plena “depuração ideológica” das correntes de esquerda do justicialismo – o relato memorial acaba por constatar a fragmentação e a divisão do peronismo.
This article intends to analyze the representation of the Independence of Argentina in the fiction feature film El santo de la espada (Leopoldo Torre Nilsson, 1970). Throughout this period, the film ...production was strongly controlled by the State – especially by the censorship laws –, at the same time, it led to the growth of the historical cinema. This genre spread an official version of history and of the foundational narratives that fit well with the nationalist speech of the dictatorship (1966-1973). These films give monumental aspect to the past in which the public could think, in an implicit or an explicit way, that the regime would be the successor and the guardian of the foundational values of the nation. Consequently, these films propose an exaltation of the Independence heroes’ military virtues and, at the same time, they don’t valorize the role played by the popular segments in the emancipation. El santo de la espada is undoubtedly the most popular successful film of this cycle (Radetich L., 2005/2006 : 60, 61).
