Bidding strategy of wind-thermal energy producers

This paper presents a stochastic mixed-integer linear programming approach for solving the self-scheduling problem of a price-taker thermal and wind power producer taking part in a pool-based electricity market. Uncertainty on electricity price and wind power is considered through a set of scenarios. Thermal units are modelled by variable costs, start-up costs and technical operating constraints, such as: forbidden operating zones, ramp up/down limits and minimum up/down time limits. An efficient mixed-integer linear program is presented to develop the offering strategies of the coordinated production of thermal and wind energy generation, having as a goal the maximization of profit. A case study with data from the Iberian Electricity Market is presented and results are discussed to show the effectiveness of the proposed approach.

The incorporation of violence by women video artists

This paper examines the way in which women video artists embodied violence in their video pieces as a strategy of critique of the patriarchal regime. Since the 1960s several generations of women artists used different strategies of self-harm or explored the physical and mental limits of their bodies to express the anguish of those who are excluded from the patriarchal society on sexist and/or racist grounds. Considering the guiding line that covers three fields – art, gender, and feminist social movements – as well as their key thinkers and scholars in Sociology, Fine Arts and the Humanities, we have built the object of study of this essay, namely, the relationship between women's video art focused on the body, violence and gender along with feminist social movements in the period ranging from 1967 to 2007, in a Western context. The methodology used had as its primary goal to create a link between the micro-sociological level of expressions, body gestures and behaviours in the videos and the macro-sociological level of broader, institutionalized social forces that are at the origin of inequalities, such as dimensions of gender and «race». This study concluded that at least since the 1960s there is the denunciation by women video artists of the general circumstances women live under, while enduring violence of various kinds, such as socio-cultural, psychological and sexual violence against women.

Mitochondrial demographic history of the Egyptian mongoose (Herpestes ichneumon), an expanding carnivore in the Iberian Peninsula

Describing the genetic patterns and the demographic history of expanding species is essential for providing insights into the processes linked with range dynamics. We analysed the mitochondrial diversity of the Egyptian mongoose (Herpestes ichneumon) across the Iberian Peninsula, where the species is currently expanding northwest. A total of 242 individuals were analysed, together with nine representatives from the North African dispersal source. Haplotype segregation and strong differentiation between Iberian and North African populations confirmed the longterm presence of the species in the Iberian Peninsula. The distribution of mitochondrial diversity fitted the pattern of a historically diversified population in southern Iberia, from which the recent dispersals into northern areas may have occurred. Higher levels of haplotype and nucleotide diversities in the northern areas, together with the heterogeneous distribution of pairwise population differentiations and the weak signal for isolationbydistance suggest the existence of longdispersal migrants across the Iberian Peninsula. Sudden and spatial expansion scenarios of H. ichneumon in the Iberian Peninsula were supported by mismatch analysis and marginally supported by neutrality tests. However, the precise time of occurrence of the detected expansion remains unclear. Future studies should incorporate additional markers in order to further clarify the population dynamics of the Egyptian mongoose in its Iberian range.
