Synaesthesia is a condition in which one type of stimulation evokes the sensation of another, as when the hearing of a sound produces photisms, i.e. mental percepts of colours. R is a 20 year old colour blind subject who, in addition to the relatively common grapheme-colour synaesthesia, presents a rarely reported cross modal perception in which a variety of visual stimuli elicit aura-like percepts of colour. In R, photisms seem to be closely related to the affective valence of stimuli and typically bring out a consistent pattern of emotional responses. The present case study suggests that colours might be an intrinsic category of the human brain. We developed an empirical methodology that allowed us to study the subject's otherwise inaccessible phenomenological experience. First, we found that R shows a Stroop effect elicited by photisms despite the fact that he does not show a regular Stroop with real colours. Secondly, by manipulating the colour context we confirmed that colours can alter R's emotional evaluation of the stimuli. Furthermore, we demonstrated that R's auras may actually lead to a partially inverted emotional spectrum where certain stimuli bring out emotional reactions opposite to the normal ones. These findings can only be accounted for by considering R's subjective colour experience or qualia. Therefore the present paper defends the view that qualia are a useful scientific concept that can be approached and studied by experimental methods

The book proposes an alternative model of technological development, that of engaging technologies. This model studies the way in which technological development can be perfect towards technological solutions compatible with sustainable development, with the ideals of solidarity or with cooperative and or only competitive participation. In short, the book is an analytical, descriptive and normative journey around the concept of "endearing technologies" coined by Miguel Ángel Quintanilla, which highlights the democratic values for the control of technology as opposed to the purely intrinsic values of technical efficiency and performance, as opposed to the automatic and uncontrolled tendency of technology.

The removal of water from mines was one of the key issues that former miners had to deal with. Roman colonists brought new technology to the Iberian Peninsula that addressed this problem. However, they did not invent this technology because it had already been applied to the growth of other endeavours in the Hellenistic society throughout the Eastern Mediterranean. In the mine, the Archimedes screw, waterwheels, bucket pulleys, and Ctesibius pumps were the primary drainage systems. In this essay, the primary characteristics, and modes of operation of machines are examined. Without leaving out the most significant finds made in the southwest of the Iberian Peninsula, one of the regions with the longest history of mining exploitation. To serve as a foundation for future research in this field, this work compares the primary mining mechanisms in ancient Huelva on a qualitative and quantitative level by the implementation of a TOPSIS methodology, a multi-criteria decision analysis method.

Ignorance is often a valid excuse for wrongdoing. But authors such as William FitzPatrick argued that ignorance is culpable if we could have reasonably expected the agent to take action that would have corrected or prevented it, given his capabilities and the opportunities provided by the context, but failed to do so due to vices such as laziness, indifference, disdain, etc. Guilty ignorance is still present in the debate and, in recent times, has become more pressing with the problem of technological responsibility. In this paper, an internalist perspective of culpable ignorance is adopted to analyze a form of culpability distribution in the technological context based on dispositional beliefs. Thus, two types of responsibility are found. By examining the implications of culpable ignorance, we realize that we can respond to the unambiguous idea that an engineer is morally and epistemically responsible for certain facts.
