Nanotechnology in food industry II: risk assessment and legislation

Currently, there is increasing use of nanomaterials in the food industry thanks to the many advantages offered and make the products that contain them more competitive in the market. Their physicochemical properties often differ from those of bulk materials, which require specialized risk assessment. This should cover the risks to the health of workers and consumers as well as possible environmental risks. The risk assessment methods must go updating due to more widespread use of nanomaterials, especially now that are making their way down to consumer products. Today there is no specific legislation for nanomaterials, but there are several european dispositions and regulations that include them. This review gives an overview of the risk assessment and the existing current legislation regarding the use of nanotechnology in the food industry.

Humanism is a violence typical of the beasts. Philosozing with a Hammer, using Levinas and Derrida, the Measure of the Human and the Human as a measure

Levinas’s reflections arose as a critique of traditional philosophy which, since it was based on presence and identity, leads to the exclusion of the other. Instead of an onto-logical thought the Lithuanian proposes that the ipseity of the human being be constituted by alterity, and that it be so ethically, because the subject is sub-ject, that is, that which upholds, responsibility. In an attempt to take the obligatory attention to the otherness of the other even further, Derrida would develop a radical critique of the Levinasian posture. Deconstruction of every trace of ipseity and sovereignty in the relationship with the other, the reading that we have done of the work of Derrida opts for a no definable understanding of the human. That is why every de-limitation of an ethical field as a properly human implies a brutal violence that the levinasian humanism of the other tried to exceed.

Ecohumanists. Protection of physical ecology demands respect human ecology

What is the human being? Which is its origin and its end? What is the influence of the nature in the man and what is his impact on nature? Forthe animalists, men are like other animals; freedom and rationality are not signs of superiority, nor having rights over the animals. For the ecohumanists, human beings are part of nature, but is qualitatively different and superior to animals; and is the creator of the civilization. We analyze these two ecological looks. A special point is the contribution ofecohumanists -from the first half of the Renaissance, who dealt in extenso the dignity and freedom of the human being-, of Michelangelo and finally, of Mozart, through his four insurmountable operas, which display the difficulty of physical ecology to engender so much beauty, so much wealth, so much love for the creatures and so much variety.

La fictohistoria o historiografía imaginaria en las literaturas románicas desde el siglo XIX: ensayo de tipología y panorama de un género formal insospechado (II)

El doble aspecto documental y artístico de la escritura de la historia ha quedado prácticamente oculto por la insistencia en el carácter científico de la disciplina y su expulsión subsiguiente del canon literario desde el siglo XIX. El cultivo de la historiografía ficticia o imaginaria (fictohistoria) surgió entonces como un modo de salvar la literariedad de la historia, en su calidad de género formal, mediante el uso del discurso historiográfico como procedimiento retórico para conseguir un efecto de historicidad en textos que son, no obstante, claramente ficticios, y que tienen a menudo un carácter satírico o admonitorio. Esto no está reñido con el hecho de que la mayoría manifieste en primer lugar una reflexión sobre el devenir de la humanidad, es decir, sobre la Historia. Los ejemplos de este género son relativamente abundantes y se pueden clasificar en varias categorías temáticas. Esta segunda parte del estudio se centra en la historia prospectiva.
