Electricity is an indicator that shows the progress of a civilization; it is a product that has greatly changed the way we think about the world. Electricity price forecasting became a fundamental task in all countries due to the deregulation of the electricity market in the 1990s. This work examines the effectiveness of using multiple variables for price prediction given the large number of factors that could influence the price of the electricity market. The tests were carried out over four (...) periods using data from Spain and deep learning models. Two different attribute selection methods based on Pearson’s correlation coefficient have been used to improve the efficiency of the training process. The variables used as input to the different prediction models were chosen, considering those most commonly used previously in the literature. This study attempts to test whether using time series lags improves the non-use of lags. The results obtained have shown that lags improve the results compared to a previous work in which no lags were used. (shrink)

Although entrepreneurial intention has been widely studied using cognitive models, we still lack entrepreneurial vocation and, therefore, lack disruptive innovations. Entrepreneurship scholars have some understanding of the reasons underlying this weakness, although there is much room for improvement in our learning concerning how to promote entrepreneurship among university students, especially in the transformed context of digital technologies. This paper focuses on the early stages of start-up, and in particular seeks to evaluate what role social and psychological factors play in the (...) development of entrepreneurial intentions. Drawing on network theory, we consider the impact of social networks on entrepreneurial intention. Specifically, we analyze the influence of two types of social networks: face-to-face and online social networks, with the latter proving especially important in digital transformations. In addition, based on affective congruency theory, we relate affect with entrepreneurial intention. Particularly, we evaluate the influence of positive and negative dispositional affectivity on the formation of entrepreneurial intentions. Finally, since affect and emotions can also be related with social relationships, we analyze whether dispositional affectivities influence entrepreneurial intention through the mediation effect of social networks. Using structural equation modeling, we confirm the impact of both online and face-to-face social networks, as well as positive dispositional affectivity on entrepreneurial intention for 589 higher education students in Spain. However, negative dispositional affectivity is not seen to influence entrepreneurial intention. Furthermore, both face-to-face and online social networks are influenced by positive dispositional affectivity. Moreover, these two types of networks can even partially mediate the relationship between positive dispositional affectivity and entrepreneurial intention. Positive dispositional affectivity can thus influence entrepreneurial intention in two different ways: directly and indirectly through both face-to-face and online social networks. This study provides further insights and adds to the literature on affect, social networks, and entrepreneurial intention. From a broader perspective, we also contribute to the literature on disruptive innovations by explaining how the development of entrepreneurial intentions would have positive consequences for university students vis-à-vis achieving these disruptive innovations.

The aim of our experiment was to analyse the effect of the emotional valence (positive, negative, or neutral) on true and false recognition, matching the arousal, frequency, concreteness, and associative strength of the study and recognition words. Fifty younger adults and 46 healthy older adults performed three study tasks (with words of different valence: positive, negative, neutral) and their corresponding recognition tests. Two weeks later, they performed the three recognition tests again. The results show that words with a negative valence (...) produced less true recognition and less false recognition than words with a positive or neutral valence, in both younger and older adults, on the immediate recognition test. This pattern of results was also found in the younger adults on the delayed recognition test, whereas in the older participants, these differences disappeared. Thus, when arousal is controlled, both younger and older adults tend to recognise negative information worse than positive or neutral information, but they also commit fewer errors. Results would suggest that the greater arousal commonly associated with negative stimuli, rather than their own valence, could explain some of the contradictory results found in the literature.

Lucrecio plantea una concepción de la realidad diferente a Epicuro, sobre todo porque ejerce la separación entre dos niveles ontológicos: el de la ontología especial y el de la ontología general. Lejos de la interpretación de que Lucrecio desprecia el latín sostenemos que intencionadamente utiliza términos latinos y que no utiliza la palabra átomo, para poder distanciarse de los debates de los aristotélicos y de los propios epicúreos sobre el tema.

I defend a Deferred Ostension view of quotation, on which quotation-marks are the linguistic bearers of reference, functioning like a demonstrative; the quoted material merely plays the role of a demonstratum. On this view, the quoted material works like Nunberg’s indexes in his account of deferred ostensión in general. The referent is obtained through some contextually suggested relation; in the default case the relation will be … instantiates the linguistic type __, but there are other possibilities. In this way, the (...) deferred ostension view deals with a problem I pointed out for the identity proposal in my earlier work, that we do not merely refer with quotations to expression-types, but also to other entities related in some way to the relevant token we use: features exhibited by the token distinct from those constituting its linguistic type, features exhibited by other tokens of the same type but not by the one actually used (as when, by using a graphic token, we refer to its phonetic type), or even other related tokens (see the examples on p. 261 of García-Carpintero 1994).

This paper proposes an epistemological approach to analyse social-ecological systems from a process perspective in order to better tackle the co-constitution of the social and the ecological and the dynamism of these systems. It highlights the usefulness of rethinking our conceptual tools taking processes and relations as the main constituents of reality instead of fundamental substances or essences. We introduce the concept of experience as understood in radical empiricism to critically revise our available concepts through focusing on the concept of (...) difference, exploring apparent contradictions and engaging in assemblage thinking.

Social network sites are a new communication channel to convey CSR information. They are interactive channels that let users participate, spread content and generate positive and negative electronic word-of-mouth about companies that can dramatically affect their reputation and future business. To identify the factors behind this behaviour, we designed a causal model to explain the intention to both comment on and share a negative corporate social responsibility news posted on Facebook. We included the following as explanatory variables: social consciousness, environmental (...) consciousness, information usefulness, corporate image and attitude towards sharing and commenting on CSR news. We surveyed 208 Facebook users who evaluated a fictitious news item about an environmental issue. We observed that social and environmental consciousness influences the usefulness of information and the attitude towards behaviour, which may explain the eWOM intention of the specific news. However, corporate image can cause people to refrain from generating eWOM and spreading the news on their friend social network. (shrink)

ABSTRACTPrior research has found a relationship between perceived facial attractiveness and perceived personal trustworthiness. We examined the time course of attractiveness relative to trustworthiness evaluation of emotional and neutral faces. This served to explore whether attractiveness might be used as an easily accessible cue and a quick shortcut for judging trustworthiness. Detection thresholds and judgment latencies as a function of expressive intensity were measured. Significant correlations between attractiveness and trustworthiness consistently held for six emotional expressions at four intensities, and neutral (...) faces. Importantly, perceived attractiveness preceded perceived trustworthiness, with lower detection thresholds and shorter decision latencies. This reveals a time course advantage for attractiveness, and suggests that earlier attractiveness impressions could bias trustworthiness inferences. A heuristic cognitive mechanism is hypothesised to ease processing demands by relying on simple a... (shrink)

Recent debates on phenomenal consciousness have shown renewed interest for the idea that experience generally includes an experience of the self – a self-experience – whatever else it may present the self with. When a subject has an ordinary experience (as of a bouncing red ball, for example), the thought goes, she is not just phenomenally aware of the world as being presented in a certain way (a bouncy, reddish, roundish way in this case); she is also phenomenally aware of (...) the fact that it is presented to her. This supposed phenomenal dimension has been variously called “mineness”, “for-me-ness”, “pre-reflective self-awareness” and “subjective character”, among others. This view, associated with historical figures such as William James, Husserl, Merleau-Ponty and Sartre, is attracting a new surge of attention at the crossroads of phenomenology, analytic philosophy of mind and the philosophy of cognitive science, but also intense controversy. This book explores some of the questions running through the ongoing debate on the putative subjective dimension of experience: Does it exist?, the existence question; What is it?, the essence question; What is it for?, the function question; and What else does it explain?, the explanation question. The volume also surveys various domains of human experience, both normal and pathological, where a “sense of self” might be at play, including agency, bodily awareness, introspection, memory, emotions and values, and offers insights into the possible relations between the notions of subjective awareness involved. The first part of the book is devoted to more sceptical or deflationary views about self-experience, and the second, to more robust ones. (shrink)

The introduction of a new analytical method, due fundamentally to François Viète and René Descartes and the later dissemination of their works, resulted in a profound change in the way of thinking and doing mathematics. This change, known as process of algebrization, occurred during the seventeenth and early eighteenth centuries and led to a great transformation in mathematics. Among many other consequences, this process gave rise to the treatment of the results in the classic treatises with the new analytical method, (...) which allowed new visions of such treatises and the obtaining of new results. Among those treatises is the Arithmetic of Diophantus of Alexandria which was written, using the new algebraic language, by the French mathematician Jacques Ozanam, who in addition to profusely increasing the original problems of Diophantus, solved them in a general way, thus obtaining many geometric consequences. The work is handwritten, it has never been published, it has been lost for almost 300 years, and the known references show its importance. We will show that Ozanam’s manuscript was quoted as an important work on several occasions by others mathematicians of the time, among whom G. W. Leibniz stands out. Once the manuscript has been located, our aim in this article is to show and analyze this work of Ozanam, its content, its notation and its structure and how, through the new algebraic method, he not only solved and expanded the questions proposed by Diophantus, but also introduced a connection between the algebraic solutions and what he called geometric determinations by obtaining loci from the solutions.

In lieu of an abstract, here is a brief excerpt of the content:Diacritics 30.4 (2000) 102-122 [Access article in PDF] How To Tell a Mestizo from an Enchirito® Colonialism and National Culture in the Borderlands Michael Hames-garcia I began to think, "Yes, I'm a chicana but that's not all I am. Yes, I'm a woman but that's not all I am. Yes, I'm a dyke but that doesn't define all of me. Yes, I come from working class origins, but I'm (...) no longer working class. Yes, I come from a mestizaje, but which parts of that mestizaje get privileged? Only the Spanish, not the Indian or black." I started to think in terms of mestiza consciousness. What happens to people like me who are in between all of these different categories? What does that do to one's concept of nationalism, of race, ethnicity, and even gender? I was trying to articulate and create a theory of a Borderlands existence.... I had to, for myself, figure out some other term that would describe a more porous nationalism, opened up to other categories of identity. —Gloria E. Anzaldúa, InterviewsOne of the most crucial questions facing leftist activists and intellectuals today is the question of nationalism and its relation to liberation struggles. 1 A century ago, the period [End Page 102] of nation-state consolidation in Europe seemed to come to an end with the unification of Germany and Italy. European leftists of the era tended to address "the national question" primarily with regard to those European nations that were shut out or suppressed by nation-state formation. Debates about national culture resurfaced in a revolutionary context when independence movements swept Africa and Asia during and after World War II, and a substantial body of literature attempting to integrate anticolonial struggle, national liberation, and socialism arose from the capitalist "periphery." Much of this literature, and the wars for independence out of which it grew, adapted the language of nationalism to its own purposes. These movements gave new hope that national liberation struggles would prove compatible with greater human freedom and equality. Despite that hope, the destructive effects of nationalism are today visible everywhere: for example, the devastating wars in the Balkans, the repression of indigenous peoples by national bourgeoisie throughout the Americas, religious-national strife between Sinhalese and Tamils in Sri Lanka, the vertiginous intensification of national chauvinism in the United States, Western Europe, and Australia. Simultaneously, and in the context of feminist criticisms of nationalism [see, for example, Chatterjee, Nation; Lutz et al.; Mosse], attempts to unite the struggle to liberate "the nation" from colonial or neocolonial domination with progressive struggles against capitalist exploitation and against sexual- and gender-based domination continue [see, for example, Trask]. In Latin America, anticapitalist struggles lauded by Western socialists regularly take the form of national liberation struggles, such as the EZLN (Ejército Zapatista de Liberación Nacional [Zapatist National Liberation Army]) in Mexico and the FSLN (Frente Sandinista de Liberación Nacional [Sandinist National Liberation Front]) in Nicaragua. Additionally, lesbian and gay activists and theorists in the United States have frequently sought to appropriate nationalist rhetoric even as black and Chicano nationalist movements have been on the decline [see, for example, Berlant and Freeman; Moraga 145-74].Debates about anticolonial struggle and "Third World" nationalism may seem at first to be an odd context into which to introduce the work of Gloria Anzaldúa. Critical writing on Anzaldúa's work has tended not to consider its relevance to debates on the relations among capitalism, colonialism, and national culture. 2 Instead, her major work, Borderlands/La Frontera, is usually discussed (or, more often than not, simply cited) as a contribution to feminist and antiracist discussions about the construction of the self within multiple contexts of domination and about that self's resistance to oppression and struggle for recognition. 3 While acknowledging the importance of Anzaldúa's contributions to these discussions, this essay examines Borderlands as offering a forward-looking alternative to nationalism, specifically, to Chicano cultural nationalist positions articulated during the...

This essay concerns the causation involved in divine sustenance—the “pressure of the will of God” that continually upholds things in existence and supplies them with their properties and powers. My aim is to consolidate the theological doctrine of sustenance and a metaphysical theory of properties. Towards that end, I develop and motivate two consolidatory proposals, which together secure a more parsimonious theistic ontology and integrate the doctrine of sustenance and a theory of properties in a mutually enhancing way. The bulk (...) of the essay concerns the first proposal, which I explain and motivate in the first three sections. In the last two sections I explain and motivate the second proposal. (shrink)

Drawing on Brown and Fraser’s (in: Giles, Scherer (eds) Social markers in speech, Cambridge University Press, Cambridge, pp 33–62, 1979) framework for the analysis of communicative situations and Fuentes Rodríguez’s (Lingüística pragmática y Análisis del discurso, Arco Libros, Madrid, 2000; in Estudios de Lingüística: Investigaciones lingüísticas en el siglo XXI, 2009. https://doi.org/10.14198/ELUA2009.Anexo3.04 ) model of pragmatic analysis, this paper examines three home-made recordings featuring some of the members of the terrorist cell responsible for the 2017 vehicle-ramming attacks in Barcelona and (...) Cambrils weighted as evidence during the trial held between November 2020 and May 2021 in the Spanish National High Court. The aim of this qualitative analysis is to test whether the linguistic evidence available supports the allegation that the participation in these recordings by one of the accused, Mohamed Houli Chemlal, had been planned by his interlocutors. Results show, first, that the exchanges analyzed present features indicative of both spontaneity and (limited) planification. Second, that Houli makes key contributions to the unfolding of the interactions shown in the recordings and that he does so in a cooperative and apparently relaxed manner, which could at best provide only partial support to his allegations. It is claimed that forensic linguistic analysis can generate valuable insights within terrorism-related legal proceedings. (shrink)

Les pràctiques d’okupació que sorgeixen a mitjans dels 80 al nostre país son considerades un moviment social per múltiples autors (Calle, 2005; Pruijt, 2004; Martínez, 2002).

El presente artículo sostiene la siguiente hipótesis: la inmensa mayoría de las conceptualizaciones teóricas con las que, a inicios del siglo XXI, se intenta dar cuenta de la subjetividad contemporánea son explícita o subrepticiamente reelaboraciones del concepto de superhombre. De ciborgs a posthumanos, pasando por una amplia y variada gama de sujetos contemporáneos, se puede apreciar que el concepto de Übermensch aporta las claves fundamentales con las cuales deconstruir el concepto de identidad fija que pone en juego el universalismo abstracto. (...) Siguiendo la teorización de Nietzsche, estas nuevas posiciones teóricas proponen una forma particular y concreta de vida como alternativa a las dicotomías y trasmundos con que la metafísica construyó a los sujetos del pasado. Sin embargo, estas propuestas han pasado por alto algo fundamental. Para demostrarlo, proponemos una relectura de Nietzsche y de dichos conceptos con el objetivo de plantear una nueva manera de pensar sobre la vida. (shrink)

Dating manuscripts is a difficult task – particularly when these are not expressly datemarked, but even when they are. Factors such as the existence of successive copies that continue and repeat established models and production methods make dating a challenging task.

By means of a study protocol, errors in the dating of (...) manuscripts ms6, ms10, ms26 and ms29 are successfully detected and corrected, and alternative dating proposed. (shrink)

The aims of the study were to identify coach profiles and examine whether participants from distinct profiles significantly differed on burnout, emotions and coping. A sample of 268 athletes (Mage = 29.34; SD = 12.37), completed a series of self-reported questionnaires. Cluster analyses revealed two coach leadership profiles: (a) profile 1 with high scores of training and instruction, authoritarian behavior, social support and positive feedback, and a low score of democratic behavior; and (b) profile 2 with low levels in training (...) and instruction, authoritarian behavior, social support and positive feedback and high levels in democratic behavior. Results of MANOVAs indicated significant differences across coach profiles on reduced accomplishment, sport devaluation, happiness and seeking support and marginal differences on dejection, logical analysis, imagery/thought control, and excitement. Moreover, coach leadership profiles were not confounded by demographic variables (level of competition, gender, age, number of practice hours, professional versus no professional athletes). As a conclusion, the profile approach offered a holistic way to examine coach leadership in sport as two distinct coach profiles emerged from the cluster analyses with an unexpected combination of coach leadership dimensions.

This paper presents a systematic investigation of fuzzy Galois connections in the sense of R. Bělohlávek [1], from the point of view of enriched category theory. The results obtained show that the theory of enriched categories makes it possible to present the theory of fuzzy Galois connections in a succinct way; and more importantly, it provides a useful method to express and to study the link and the difference between the commutative and the non-commutative worlds.

A mística, embora implique certa relação com o suprassensível, apresenta traços fenomenológicos comuns com a experiência sensível do belo e com a criação artística. Este artigo pretende examinar as imprecisas fronteiras entre a mística e a estética a partir de três autores do século XX, estudiosos de Plotino: Evelyn Underhill, Vladimir Jankélévitch e Juan David García Bacca. Primeiramente, será analisado o estatuto da sensibilidade, da beleza e da arte na espiritualidade de Underhill. Em seguida, será verificado de que modo o (...) campo da inefabilidade, ressaltado ao longo da obra de Jankélévitch e, em particular, em sua estética musical, garante a aproximação entre as duas áreas. Em terceiro lugar, será investigada a confluência do caminho místico e do caminho da Beleza na leitura feita por García Bacca do itinerário, prescrito por Plotino, rumo ao Transcendente. A título de conclusão, serão destacados pontos de convergência e de divergência entre os autores. Palavras-chave: Beleza. Arte. Inefabilidade. Transcendente. Neopla¬tonismo. (shrink)

The American Society for Bioethics and Humanities promulgated standards for clinical ethics consultants and is currently developing a national Quality Attestation in Clinical Ethics Consultation to assist facilities in ensuring that those performing clinical ethics consultations meet minimum standards. As the field moves towards such professionalization, there is a need to provide access to qualified clinical ethicists at a broad range of medical facilities. Currently, however, there are insufficient numbers of trained clinical ethicists to staff all healthcare facilities, and many (...) facilities lack the necessary resources to hire staff clinical ethicists. In this review, we describe several models for providing expert clinical ethics support to remote facilities that lack access to qualified clinical ethicists. Based on this analysis, we recommend telemedicine as the optimal model providing expert support to local ethics committee members tasked with providing clinical ethics consultation services.

Since the 1980s, there has been a significant increase in the number of studies concerning Andalusian rural settlements linked to irrigated agriculture, both related to large suburban green belts and to small hydraulic systems. In the vast areas where water is scarce, the settlement apparently would have been concentrated in cities and fortified towns, leaving without population most of the dry lands between them. However, thanks to the intensive survey of one of these regions, La Mancha’s Southeastern area, we are (...) recording a dense rural settlement corresponding to a pattern unknown until now. It consists basically of small villages in plain, devoid of community defense elements, which must have been inhabited by humble peasants, judging by the modesty of the architecture and domestic goods. Surely they make use of the scanty natural resources, which have traditionally oriented the economy of the region towards livestock and rainfed agriculture. In particular, the studied settlement would be related to the demand of wool for the export oriented textile production of the region, within the framework of the commercial expansion of that period. Apparently, most of those villages could have appeared in the eleventh century, disappearing in the middle of the thirteenth century because of the Christian conquest. Their existence would be associated with a general context of population growth that pushed the competition between urban elites and peasants pursuing the privileged agricultural areas, as well as the colonization of less favorable production areas.
