Joaquim Mir y la tienda de juguetes: microhistoria de un retrato

¿Puede un retrato pictórico suscitar un ejercicio de microhistoria? Nuestra investigación tratará de aportar una respuesta positiva a esta cuestión, analizando para ello uno de los pocos retratos del pintor postimpresionista Joaquim Mir Trinxet, fechado en 1926. El protagonista representado no es otro que el suegro del pintor, Antoni Estalella i Trinxet, un insigne personaje de Vilanova y la Geltrú (Barcelona) que vivió entre dos siglos. La obra está ambientada en la tienda de juguetes de la familia, convirtiéndose así en una de las escasas pinturas que han captado el interior de una juguetería en la España anterior a la Guerra Civil. Gracias a los trabajos de archivo realizados, este artículo reúne diversos documentos inéditos que permiten reconstruir no sólo la vida del retratado, que llegó a ser corresponsal de Francisco Pi y Margall, sino también el ambiente social, artístico y comercial de Vilanova, en un período que abarca desde la década de 1870 a la primera mitad del siglo XX, en plena “Edad de Oro” de la industria juguetera. Es esta una propuesta de metodología historiográfica cuyo recorrido comienza en el oficio arcaico de la tonelería para desembocar al fin en los albores del comercio moderno de juguetes.

Genetic differentiation of Euterpe edulis Mart. populations estimated by AFLP analysis

Heart-of-palm (Euterpe edulis Mart.) is a wild palm with a wide distribution throughout the Atlantic Rainforest. Populations of E. edulis represent important renewable natural resources but are currently under threat from predatory exploitation. Furthermore, because the species is indigenous to the Atlantic Rainforest, which is located in the most economically developed and populated region of Brazil, social and economic pressures have devastated heart-of-palm forests. In order to estimate the partitioning of genetic variation of endangered E. edulis populations, 429 AFLP markers were used to analyse 150 plants representing 11 populations of the species distribution range. Analysis of the genetic structure of populations carried out using analysis of molecular variance (AMOVA) revealed moderate genetic variation within populations (57.4%). Genetic differentiation between populations (F-ST = 0.426) was positively correlated with geographical distance. These results could be explained by the historical fragmentation of the Atlantic coastal region, together with the life cycle and mating system The data obtained in this work should have important implications for conservation and future breeding programmes of E. edulis.

A 'Teague' and a 'True Briton': Charles Johnstone, Ireland, and Empire

Charles Johnstone's literary output - which included Chrysal: or, the Adventures of a Guinea (1760) and a series of novels between 1762 and 1781 prior to his departure for Calcutta in 1782 - features a marked geographical and historical preoccupation with empire. The trajectory of Johnstone's life from Carrigogunnell and Dublin in Ireland, to London, and finally to Calcutta, indicates the remarkable possibilities for self-transformation which empire from Ireland to India offered during the eighteenth century. This paper examines the significance of empire in Johnstone's oeuvre, and identifies for the first time a series of articles written by him in The Calcutta Gazette in 1785.

Psychological distress among family carers of oesophageal cancer survivors the role of illness cognitions and coping

Objective: The research aimed to determine the extent to which illness cognitions and coping explain psychological distress (fear of cancer recurrence, anxiety and depression symptoms) among family carers of survivors of oesophageal cancer.


Methods: Carers of patients registered with the Oesophageal Patients' Association in the UK were mailed a questionnaire booklet containing questions about medical and demographic variables, the Illness Perception Questionnaire-Revised, the Cancer Coping Questionnaire, the Concerns about Recurrence Scale and the Hospital Anxiety and Depression Scale.


Results: Complete responses were received from 382 family carers (75% male; mean (SD) age=62 (10.91) years). Regression models indicated that the variables measured could explain between 35 and 49% of the variance in psychological distress among carers. Illness cognitions (particularly perceptions of the cause of, consequences of and personal control over oesophageal cancer and the carer's understanding of the condition) explained the majority of this variance. Positive focus coping strategies were also found to be important in explaining psychological distress.


Conclusion: The results of this study are consistent with previous research demonstrating that illness cognitions are significant correlates of adaptive outcomes, thereby suggesting that cognition-based interventions could potentially be effective in minimizing emotional distress among family carers of oesophageal cancer survivors.

Asymptotic layer-type model of high pressure direct current glow discharge in electronegative gases

Here a self-consistent one-dimensional continuum model is presented for a narrow gap plane-parallel dc glow discharge. The governing equations consist of continuity and momentum equations for positive and negative ions and electrons coupled with Poisson's equation. A singular perturbation method is developed for the analysis of high pressure dc glow discharge. The kinetic processes of the ionization, electron attachment, and ion-ion recombination are included in the model. Explicit results are obtained for the asymptotic limits: delta=(r(D)/L)(2)--> 0, omega=(r(S)/L)(2)--> 0, where r(D) is the Debye radius, r(S) is recombination length, and L is the gap length. The discharge gap divides naturally into four layers with multiple space scales: anode fall region, positive column, transitional region, cathode fall region and diffusion layer adjacent to the cathode surface, its formation is discussed. The effects of the gas pressure, gap spacing and dc voltage on the electrical properties of the layers and its dimension are investigated. (C) 2000 American Institute of Physics.

A 64-point fourier transform chip for video motion compensation using phase correlation

Details of a new low power fast Fourier transform (FFT) processor for use in digital television applications are presented. This has been fabricated using a 0.6-µm CMOS technology and can perform a 64 point complex forward or inverse FFT on real-time video at up to 18 Megasamples per second. It comprises 0.5 million transistors in a die area of 7.8 × 8 mm and dissipates 1 W. The chip design is based on a novel VLSI architecture which has been derived from a first principles factorization of the discrete Fourier transform (DFT) matrix and tailored to a direct silicon implementation.

Appealing to the Republic of Letters: An Autopsy of Anti-venereal Trials in Eighteenth-century Mexico

This study analyses the narrative elements of a little-known report into anti-venereal trials written by an Irish military physician-surgeon, Daniel O'Sullivan (1760–c.1797). It explores the way in which O'Sullivan as the narrator of the Historico-critical report creates medical heroes and anti-heroes as a means to criticise procedures initiated by staff in the Hospital General de San Andrés, Mexico City. The resulting work depicts a much less positive picture of medical trials and hospital authorities in this period than has been recorded to date, and provides a critical and complicated assessment of one of Spain's leading physicians of the nineteenth century, Francisco Javier Balmis (1753–1819).

Hydroclimatic changes during the 8.2 ka event inferred from Irish subfossil pines

A significant cold event, derived from the Greenland ice cores, took place between 8200 and 8000 cal. BP. Modeling of the event suggests that higher northern latitudes would have experienced considerable decreases in precipitation and that Ireland would have witnessed one of the greatest depressions. However, no well-dated proxy record exists from the British Isles to test the model results. Here we present independent evidence for a phase of major pine recruitment on Irish bogs at around 8150 cal. BP. Dendrochronological dating of subfossil trees from three sites reveal synchronicity in germination across the region, indicative of a regional forcing, and allows for high-precision radiocarbon based dates. The inner-rings of 40% of all samples from the north of Ireland dating to the period 8,500-7,500 cal. BP fall within a 25-year window. The concurrent colonization of pine on peatland is interpreted as drier conditions in the region and provide the first substantive proxy data in support of a significant hydrological change in the north of Ireland accompanying the 8.2 ka event. Our results also indicate that the apparent temporal asynchrony between anomalies in proxy records at the time could be a result of differences in dating methods.

The Reintegration of Sex Offenders: Barriers and Opportunities for Employment

The process of reintegration of offenders after release from prison, or during a community sentence, is a key aim of criminal justice policy. This article provides details from recent research that investigated the barriers and opportunities to employment for sex offenders. The authors describe the barriers that are faced by sex offenders and the anxieties that employers experience when employing sex offenders. The authors conclude that the approach taken by the State is less than reintegrative and serves to increase the barriers and reduce the opportunities for employment for sex offenders.

The DietCompLyf study: A prospective cohort study of breast cancer survival and phytoestrogen consumption

DietCompLyf is a multi-centre prospective study designed to investigate associations between phytoestrogens - naturally occurring plant compounds with oestrogenic properties - and other diet and lifestyle factors with breast cancer recurrence and survival. 3159 women with grades I-III breast cancer were recruited 9-15 months post-diagnosis from 56 UK hospitals. Detailed information on clinico-pathological, diet, lifestyle and quality of life is collected annually up to 5 years. Biological samples have also been collected as a resource for subsequent evaluation. The characteristics of the patients and associations between pre-diagnosis intake of phytoestrogens (isoflavones and lignans; assessed using the EPIC-Norfolk UK 130 question food frequency questionnaire) and breast cancer (i) risk factors and (ii) prognostic factors are described for 1797 women who had complete data for all covariates and phytoestrogens of interest. Isoflavone intakes were higher in the patients who were younger at diagnosis, in the non-smokers, those who had breast-fed and those who took supplements. Lignan intakes were higher in patients with a higher age at diagnosis, in ex-smokers, those who had breast-fed, who took supplements, had a lower BMI at diagnosis, lower age at menarche and were nulliparous. No significant associations between pre-diagnosis phytoestrogen intake and factors associated with improved breast cancer prognosis were observed. The potential for further exploration of the relationship between phytoestrogens and breast cancer recurrence and survival, and for the establishment of evidence to improve dietary and lifestyle advice offered to patients following breast cancer diagnosis using DietCompLyf data is discussed.

Robust visual tracking using structurally random projection and weighted least squares

Sparse representation based visual tracking approaches have attracted increasing interests in the community in recent years. The main idea is to linearly represent each target candidate using a set of target and trivial templates while imposing a sparsity constraint onto the representation coefficients. After we obtain the coefficients using L1-norm minimization methods, the candidate with the lowest error, when it is reconstructed using only the target templates and the associated coefficients, is considered as the tracking result. In spite of promising system performance widely reported, it is unclear if the performance of these trackers can be maximised. In addition, computational complexity caused by the dimensionality of the feature space limits these algorithms in real-time applications. In this paper, we propose a real-time visual tracking method based on structurally random projection and weighted least squares techniques. In particular, to enhance the discriminative capability of the tracker, we introduce background templates to the linear representation framework. To handle appearance variations over time, we relax the sparsity constraint using a weighed least squares (WLS) method to obtain the representation coefficients. To further reduce the computational complexity, structurally random projection is used to reduce the dimensionality of the feature space while preserving the pairwise distances between the data points in the feature space. Experimental results show that the proposed approach outperforms several state-of-the-art tracking methods.
