Wind energy and wind power forecast errors have a direct impact on operational decision problems involved in the integration of this form of energy into the electricity system. As the relationship between wind and the generated power is highly nonlinear and time-varying, and given the increasing number of available forecasting techniques, it is possible to use alternative models to obtain more than one prediction for the same hour and forecast horizon. To increase forecast accuracy, it is possible to combine the different predictions to obtain a better one or to dynamically select the best one in each time period. Hybrid alternatives based on combining a few selected forecasts can be considered when the number of models is large. One of the most popular ways to combine forecasts is to estimate the coefficients of each prediction model based on its past forecast errors. As an alternative, we propose using multivariate reduction techniques and Markov chain models to combine forecasts. The combination is thus not directly based on the forecast errors. We show that the proposed combination strategies based on dimension reduction techniques provide competitive forecasting results in terms of the Mean Square Error ; The second author, Pilar Poncela, acknowledges financial support from the Spanish Government, Ministry of Science, contract grant PID2019-108079GB-C22/AEI/10.13039/501100011033

The practice of karo kari allows family, especially fathers, brothers and sons, to take the lives of their daughters, sisters and mothers if they are accused of adultery. This volume examines the central position of karo kari in the social, political and juridical structures in Upper Sindh, Pakistan. Drawing connections between local contests over marriage and resources, Nafisa Shah unearths deep historical processes and power relations. In particular, she explores how the state justice system and informal mediations inform each other in state responses to karo kari, and how modern law is implicated in this seemingly ancient cultural practice

The accident at the Fukushima nuclear power plant in Japan on 11 March 2011 unleashed an environmental, economic, political and humanitarian crisis whose effects are still felt today. This study analyses press coverage of the incident by three Spanish daily newspapers, Abc, El País and La Vanguardia, to determine the prevalent frames in the news articles on the disaster. Content analysis based on the stories published between March and May 2011 suggests that the most ubiquitous frames were human interest, economic consequences, political conflict, damage and environmental risks. ; El accidente de la central nuclear de Fukushima (Japón), producido el 11 de marzo de 2011, desencadenó una crisis medioambiental, económica, política y humanitaria cuyos efectos todavía perduran. En este trabajo se aborda la cobertura del suceso por parte de los diarios españoles Abc, El País y La Vanguardia, con el propósito de determinar los frames predominantes en los textos informativos e interpretativos asociados a él. Del análisis de contenido aplicado a las piezas publicadas por las tres cabeceras entre marzo y mayo de 2011, emergen cinco enfoques: interés humano, consecuencias económicas, conflicto político, daños y riesgos medioambientales.

Neoconservatism in US foreign policy is a hotly contested subject, yet most scholars broadly agree on what it is and where it comes from. From a consensus that it first emerged around the 1960s, these scholars view neoconservatism through what we call the '3Ps' approach, defining it as a particular group of people ('neocons'), an array of foreign policy preferences and/or an ideological commitment to a set of principles. While descriptively intuitive, this approach reifies neoconservatism in terms of its specific and often static 'symptoms' rather than its dynamic constitutions. These reifications may reveal what is emblematic of neoconservatism in its particular historical and political context, but they fail to offer deeper insights into what is constitutive of neoconservatism. Addressing this neglected question, this article dislodges neoconservatism from its perceived home in the '3Ps' and ontologically redefines it as a discourse. Adopting a Foucauldian approach of archaeological and genealogical discourse analysis, we trace its discursive formations primarily to two powerful and historically enduring discourses of the American self — virtue and power — and illustrate how these discourses produce a particular type of discursive fusion that is 'neoconservatism'. We argue that to better appreciate its continued effect on contemporary and future US foreign policy, we need to pay close attention to those seemingly innocuous yet deeply embedded discourses about the US and its place in the world, as well as to the people, policies and principles conventionally associated with neoconservatism.

This original work is an unusual effort to relate modern constitutional politics to the moral character of American culture. Writing in non-technical language, Nagel demonstrates how judicial decisions embody wider social tendencies toward moral evasiveness, privatization, and opportunism. He shows that constitutional interpretation is often used to stifle political disagreement and, ultimately, to censor our own beliefs and traditions. The discussion ranges over such controversial topics as political correctness on the campus and in the case law, resistance to constitutional rights like abort.

SummaryThis paper investigates the history of the labour process in New Zealand's state-owned railway workshops and questions the idea that large-scale industry inevitably destroyed whatever agency skilled workers had enjoyed. It also shows that relations of production vary with the political and cultural contexts. Craft control of the labour process survived in New Zealand's state-owned railway workshops and the union played only a minor role. Jop control was more important in achieving bureaucratic instead of autocratic control over such matters as hiring and firing; the retention of apprentice-based crafts; the institutionalization of seniority; and in resisting both de-skilling and the "premium bonus". The strength and vitality of shop culture, based on craft control of the labour process, also survived and modified the Government's vigorous attempt to introduce "scientific management". In brief the article concludes that productive processes do not inevitably determine social relations of production, that capitalism has been neither homogeneous nor uniform, and that mechanization never inevitably results in de-skilling.
