Discopyge castelloi sp. nov. (Torpediniformes, Narcinidae), una nueva especie de raya eléctrica del Mar Argentino

A new species of electric ray of the family Narcinidae, Discopyge castelloi, is described from the southwestern Atlantic off Argentina. Distinctive characters of the new species are the form of the body, the posterior position of pelvic fins and the manner as pelvic fins join the caudal peduncle, the morphology of the nasal curtain and the presence of small but apparently functional eyes. Discopyge castelloi is the fourth torpediniform species reported from the area. It appears to be very rare on the shelf, though the type locality is separated from that of the paratypes by seven latitude degrees. As in the case of Torpedo puelcha, it is probable that the new species has a normal habitat deeper than that of the available specimens.

Desenvolvimento econômico e desigualdade social: um estudo sobre os aspectos sociais presentes na obra de Raúl Prebisch

This study aims to conduct an analysis on the social aspects present in the works of the Argentine economist Raúl Prebisch (1901-1986). Based on the author's research on the economic development of the peripheral countries, it will be demonstrated how the social and economic factors have interconnected in the developmental theory of the peripheral worldwide economy. To achieve this goal, the six works of Prebisch considered essentials by Economic Commission for Latin America and the Caribbean (ECLAC) were used as main bibliographic axis. Such texts are: Introduction to Keynes, The Economic Development of Latin America and Its Principal Problems, Economic development or monetary stability: the false dilemma, Towards a Dynamic Development Policy for Latin America, .Change and Development: Latin America's Great Task, Capitalismo periférico: crisis y transformación, Five stages in my thinking on development. Firstly the topics essential to economic development according to the author will be exposed, such as industrialization of peripheral countries as a means of raising the income of masses and the way it should be coordinated beyond the theoretical author's choice on historical events, the evolution of the deterioration of terms of trade between peripheral and central countries and the need for productivity gains to increase the income of the worker. Afterwards it will be exposed how such terms align with social inequalities and which definitions are incorporated by the author on the subject
