In a variety of synaesthesia, photisms result from affect-laden stimuli as emotional words, or faces of familiar people. For R, who participated in this study, the sight of a familiar person triggers a mental image of "a human silhouette filled with colour". Subjective descriptions of synaesthetic experiences induced by the visual perception of people's figures and faces show similarities with the reports of those who claim to possess the ability to see the aura. It has been proposed that the purported auric perception may be easily explained by the presence of a specific subtype of cross-modal perception. We analyse the subjective reports of four synaesthetes who experience colours in response to human faces and figures. These reports are compared with descriptions of alleged auric phenomena found in the literature and with claims made by experts in esoteric spheres. The discrepancies found suggest that both phenomena are phenomenologically and behaviourally dissimilar

Corporate governance (CG) can be seen to operate through a 'double agency' relationship: one between the shareholders and corporate management, and another between the corporate management and the firm's employees. The CG and labour management of firms are closely related. A particularly productive way to study how CG affects and is affected by the employment relationship has been to compare CG across countries. The contributions of this paper to that literature are threefold. (1) An integration of aspects of the labour management literature in the CG debate. (2) Based on a sample of about 1000 firms from 31 countries, we find evidence of complementarities between the CG and the labour management of firms. Extreme cases, in general, outperform mixed cases. (3) Firm differences within countries are more important than scholars have assumed so far. We present the results of the study and implications for future research and for practice.

The European hummingbird hawkmoth Macroglossum stellatarum is a diurnal nectar forager like the honeybee, and we expect similarities in their sensory ecology. Using behavioural tests and electroretinograms, we studied the spectral sensitivity of M. stellatarum. By measuring ERGs in the dark-adapted eye and after adaptation to green light, we determined that M. stellatarum has ultraviolet, blue and green receptors maximally sensitive at 349, 440 and 521 nm, and confirmed that green receptors are most frequent in the retina. To determine the behavioural spectral sensitivity of foraging moths, we trained animals to associate a disk illuminated with spectral light, with a food reward, and a dark disk with no reward. While the spectral positions of sensitivity maxima found in behavioural tests agree with model predictions based on the ERG data, the sensitivity to blue light was 30 times higher than expected. This is different from the honeybee but similar to earlier findings in the crepuscular hawkmoth Manduca sexta. It may indicate that the action spectrum of foraging hawkmoths does not represent their general sensory capacity. We suggest that the elevated sensitivity to blue light is related to the innate preference of hawkmoths for blue flowers

Studies demonstrating the benefits of ethical behavior at an individual level are scarce. The business ethics literature centers its analysis on unethical behaviors and their consequences, rather than ethical behaviors and their benefits. There is now considerable debate on the role of auditors in society and the function of accounting firms in the free market capitalist system. Specifically, the eminently ethical nature of the auditor’s work has been highlighted. Therefore, the aim of our paper is to show the impact of auditors’ sustained ethical behavior: the trust it generates. This trust results in considerable benefits for the firm due to a reduction in the costs of the partner’s supervision of the auditor. The methodology chosen to validate these claims is a survey of partner of the audit firm in auditing companies. The results of this research confirm the hypotheses raised in the theoretical model.

La conocida obra Muʿǧam al-buldān (Diccionario de los países), terminada por el geógrafo y erudito Yāqūt al-Rūmī al-Ḥamawī (m. 626/1229) un año antes de su muerte, ofrece una valiosa información sobre los múltiples topónimos recogidos por este autor. Dicha información no se limita solo a los aspectos geográficos, sino también a los literarios y biográficos, y ha sido abordada en trabajos relacionados con al-Andalus. Mi propósito en el presente artículo es realizar una primera aproximación a la imagen que Yāqūt proyecta del Mágreb a través de algunos ejemplos concretos, realizando un breve recorrido de las fuentes que empleó, entre las cuales destacó especialmente el geógrafo andalusí Abū ʿUbayd al-Bakrī (m. 487/1094), muy citado en toda la obra.

In this work, we present a new approach to solve the location management problem by using the reporting cells strategy. Location management is a very important and complex problem in mobile computing which aims to minimize the costs involved. In the reporting cells location management scheme, some cells in the network are designated as reporting cells . The choice of these cells is not trivial because they affect directly to the cost of the mobile network. This article is focused on the use of high performance computing to execute a parallel heuristic that places optimally the RCs in a mobile network, minimizing its total cost. The main goal of this work is to demonstrate that the collaborative work of different evolutionary algorithms can obtain very good results. For this reason, we have implemented a parallel heuristic and six evolutionary algorithms that works in a parallel way on a cluster to solve the RCs problem

After compulsory secondary education; many teenagers face the process of choosing a university degree. This process involves uncertainties referred to their personal abilities, interests, social expectations and professional future. The present work is aimed at determining whether the reasons behind the selection of a particular university degree differ depending on the chosen degree. Another objective is determining whether these reasons differ significantly according to gender. The sample comprises 983 students belonging to the area of social and legal sciences at the University of Seville. The obtained results reveal the existence of four main reasons behind the selection of university degrees for which significant gender-related differences were observed: easy degree, job opportunities, high wages and provision of social services. Besides, these seven reasons are observed to differ widely in six of the considered degrees

Este texto muestra cómo la tradición fenomenológica de la filosofía de la tecnología ha interrogado y cuestionado a la tecnología moderna entendida como ciencia aplicada y neutral. El análisis inicia con la indagación ontológica sobre el significado de la técnica para el hombre llevada a cabo por Heidegger y Ortega, para señalar luego la pertinencia de encontrar vínculoscon otros modos de considerar la acción práctica del hombre y explicitar con ello el acercamiento entre la racionalidad técnica con el poder humanizante de la imaginación y la creatividad. Finalmente se muestra cómo este vínculo fue desarrollado por Gaston Bachelard bajo la sugerente idea de un racionalismo inventivo que debe acompañar tanto a la práctica científica del sabio como a la construcción técnica de los fenómenos por parte del ingeniero
