The Rhetorical Construction of Corporate Logos

This research is set in the context of today’s societies, in which the corporate visual symbology of a business, corporation or institution constitutes an essential way to transmit its corporate image. Traditional discursive procedures can be discovered in the development of these signs. The rhetorical strategies developed by the great classical authors appear in the logo-symbols expressing the corporate values of today’s companies. Thus, rhetoric is emerging once again in the sense it had many centuries ago: A repertory of rules that, paradoxically, standardizes the deviations of language and whose control is synonymous with power. The main objective of this study is to substantiate the rhetorical construction of logos using as a model of analysis the classical process of creating discourse. This involves understanding logos as persuasive discourses addressed to a modern audience. Our findings show that the rhetorical paradigm can be considered as a creative model for the con­struction of an original logo consistent with a company’s image.

La visión artificial, un nuevo aliado para el análisis de imágenes artísticas

En este estudio se evalúa el rendimiento de los métodos de Bag-of-Visualterms (BOV) para la clasificación automática de imágenes digitales de la base de datos del artista Miquel Planas. Estas imágenes intervienen en la ideación y diseño de su producción escultórica. Constituye un interesante desafío dada la dificultad de la categorización de escenas cuando éstas difieren más por los contenidos semánticos que por los objetos que contienen. Hemos empleado un método de reconocimiento basado en Kernels introducido por Lazebnik, Schmid y Ponce en 2006. Los resultados son prometedores, en promedio, la puntuación del rendimiento es aproximadamente del 70%. Los experimentos sugieren que la categorización automática de imágenes basada en métodos de visión artificial puede proporcionar principios objetivos en la catalogación de imágenes y que los resultados obtenidos pueden ser aplicados en diferentes campos de la creación artística.

La recuperación mutua en personas con trastornos psicológicos o diversidad funcional a través de la práctica creativa

En el presente artículo introducimos el concepto de “recuperación mutua” y proponemos las prácticas creativas como herramientas eficientesde recuperación de personas tanto con problemas de salud mental como con algún tipo de diversidad funcional. Frente al concepto clásico de “arte-terapia” nosotros proponemos el concepto de “práctica creativa” como más compatible con el modelo de “recuperación mutua”. Para ello, en primer lugar realizamos un breve repaso crítico a la relación del arte con la locura. Seguidamente, presentamos los conceptos hermanos de “recuperación” y “recuperación mutua” en el marco de lo que se ha venido a denominar las “health humanities”. Para finalizar, describimos dos prácticas creativas que en la actualidad están siendo evaluadas en España en el contexto de un proyecto de investigacióninternacional en recuperación mutua: Los seminarios creativos con personas con trastorno mental grave en el Museo de Arte Contemporáneo de Sevilla y el grupo de teatro con personas con diversidad funcional de la Asociación Síndrome de Down-Sevilla

Effect of tailored practice and patient care plans on secondary prevention of heart disease in general practice: cluster randomised controlled trial

Objective: To test the effectiveness of a complex intervention designed, within a theoretical framework, to improve outcomes for patients with coronary heart disease. Design: Cluster randomised controlled multicentre trial. Setting: General practices in Northern Ireland and the Republic of Ireland, regions with different healthcare systems. Participants: 903 patients with established coronary heart disease registered with one of 48 practices. Intervention: Tailored care plans for practices (practice based training in prescribing and behaviour change, administrative support, quarterly newsletter), and tailored care plans for patients (motivational interviewing, goal identification, and target setting for lifestyle change) with reviews every four months at the practices. Control practices provided usual care. Main outcome measures: The proportion of patients at 18 month follow-up above target levels for blood pressure and total cholesterol concentration, and those admitted to hospital, and changes in physical and mental health status (SF-12). Results: At baseline the numbers (proportions) of patients above the recommended limits were: systolic blood pressure greater than 140 mm Hg (305/899; 33.9%, 95% confidence interval 30.8% to 33.9%), diastolic blood pressure greater than 90 mm Hg (111/901; 12.3%, 10.2% to 14.5%), and total cholesterol concentration greater than 5 mmol/l (188/860; 20.8%, 19.1% to 24.6%). At the 18 month follow-up there were no significant differences between intervention and control groups in the numbers (proportions) of patients above the recommended limits: systolic blood pressure, intervention 98/360 (27.2%) v control, 133/405 (32.8%), odds ratio 1.51 (95% confidence interval 0.99 to 2.30; P=0.06); diastolic blood pressure, intervention 32/360 (8.9%) v control, 40/405 (9.9%), 1.40 (0.75 to 2.64; P=0.29); and total cholesterol concentration, intervention 52/342 (15.2%) v control, 64/391 (16.4%), 1.13 (0.63 to 2.03; P=0.65). The number of patients admitted to hospital over the 18 month study period significantly decreased in the intervention group compared with the control group: 107/415 (25.8%) v 148/435 (34.0%), 1.56 (1.53 to 2.60; P=0.03). Conclusions: Admissions to hospital were significantly reduced after an intensive 18 month intervention to improve outcomes for patients with coronary heart disease, but no other clinical benefits were shown, possibly because of a ceiling effect related to improved management of the disease.

Neutrophil Elastase Increases Airway Epithelial Nonheme Iron Levels

Alpha-1-antitrypsin (A1AT) deficiency is characterized by increased neutrophil elastase (NE) activity and oxidative stress in the lung. We hypothesized that NE exposure generates reactive oxygen species by increasing lung nonheme iron. To test this hypothesis, we measured bronchoalveolar lavage (BAL) iron and ferritin levels, using inductively coupled plasma (ICP) optical emission spectroscopy and an ELISA, respectively, in A1AT-deficient patients and healthy subjects. To confirm the role of NE in regulating lung iron homeostasis, we administered intratracheally NE or control buffer to rats and measured BAL and lung iron and ferritin. Our results demonstrated that A1AT-deficient patients and rats postelastase exposure have elevated levels of iron and ferritin in the BAL. To investigate the mechanism of NE-induced increased iron levels, we exposed normal human airway epithelial cells to either NE or control vehicle in the presence or absence of ferritin, and quantified intracellular iron uptake using calcein fluorescence and ICP mass spectroscopy. We also tested whether NE degraded ferritin in vitro using ELISA and western analysis. We demonstrated in vitro that NE increased intracellular nonheme iron levels and degraded ferritin. Our results suggest that NE digests ferritin increasing the extracellular iron pool available for cellular uptake.

Oral Resveratrol Reduces Neuronal Damage in a Model of Multiple Sclerosis

Background: Neuronal loss in multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE), correlates with permanent neurological dysfunction. Current MS therapies have limited the ability to prevent neuronal damage. Methods: We examined whether oral therapy with SRT501, a pharmaceutical grade formulation of resveratrol, reduces neuronal loss during relapsing-remitting EAE. Resveratrol activates SIRT1, an NAD-dependent deacetylase that promotes mitochondrial function. Results: Oral SRT501 prevented neuronal loss during optic neuritis, an inflammatory optic nerve lesion in MS and EAE. SRT501 also suppressed neurological dysfunction during EAE remission, and spinal cords from SRT501-treated mice had significantly higher axonal density than vehicle-treated mice. Similar neuroprotection was mediated by SRT1720, another SIRT1-activating compound; and sirtinol, an SIRT1 inhibitor, attenuated SRT501 neuroprotective effects. SIRT1 activators did not prevent inflammation. Conclusions: These studies demonstrate that SRT501 attenuates neuronal damage and neurological dysfunction in EAE by a mechanism involving SIRT1 activation. SIRT1 activators are a potential oral therapy in MS. © 2010 by North American Neuro-Ophthalmology Society.

Convergence of partial-wave expansions for energies, scattering amplitudes and positron annihilation rates

We use many-body theory to find the asymptotic behaviour of second-order correlation corrections to the energies and positron annihilation rates in many- electron systems with respect to the angular momenta l of the single-particle orbitals included. The energy corrections decrease as 1/(l+1/2)4, in agreement with the result of Schwartz, whereas the positron annihilation rate has a slower 1/(l+1/2)2 convergence rate. We illustrate these results by numerical calculations of the energies of Ne and Kr and by examining results from extensive con?guration-interaction calculations of PsH binding and annihilation.

Fasciola hepatica: Disruption of the vitelline cells in vitro by the sulphoxide metabolite of triclabendazole

The effects of the active sulphoxide metabolite of the fasciolicide triclabendazole (Fasinex, Ciba-Geigy) on the vitelline cells of Fusciola hepatica were determined in vitro by transmission electron microscopy using both intact flukes and tissue-slice material. At a triclabendazole concentration of 15 mu g/ml the vitelline cells of intact flukes showed ultrastructural changes only after prolonged incubation periods (12-24 h). The changes observed were a swelling of the granular endoplasmic reticulum (GER) cisternae with decreased ribosomal covering in the intermediate-type cells and condensation of chromatin and disappearance of the nucleolus in the nucleus of the stem cell. Similar changes were evident more quickly (by 6 h) in whole flukes treated at the higher concentration of 50 mu g/ml. The shell globule clusters were loosely packed in the intermediate type-2 cells, and the number of intermediate type-1 cells declined with more prolonged incubation. Disruption of the nurse-cell cytoplasm was also observed from 12 h onwards. After only 6 h incubation of tissue-slice material at 50 mu g/ml, intermediate type-1 cells were absent, shell globule clusters in mature cells were loosely packed and the nurses cell cytoplasm was badly disrupted. By 12 h the vitelline cells were vacuolated and grossly abnormal. The results are discussed in relation to postulated actions of triclabendazole against the microtubule component of the cytoskeleton and against protein synthesis in the fluke.

Learning Not to Curse: Swearing, Testimony, and Truth in Olaudah Equiano’s The Interesting Narrative

This article addresses swearing and testimony in Olaudah Equiano’s The Interesting Narrative (1789) by reading the work in the context of a broader contemporary discourse concerning profane swearing and cursing. Acts of profane enunciation inform a number of key episodes in Equiano’s life, and bear particular significance for his spiritual development and abolitionist witnessing. Within the Narrative, swearing is cast as a failure of piety, civility, and humanity, and shown to be actively avenged by a retributive deity. In Britain, profane swearing was also thought to undermine the validity of legal testimony; while, in the British West Indies, slaves were denied recourse to such testimony against their oppressors. By disavowing profane swearing and cursing, the essay argues, Equiano sought to assert both the validity of his oath and the truth of his testimony against the iniquities of the British slave trade.
