Jackendoff's Foundations of Language: Brain, Meaning, Grammar, Evolution attempts to reconnect generative linguistics to the rest of cognitive science. However, by minimally acknowledging decades of work in cognitive linguistics, treating dynamical systems approaches somewhat dismissively, and clinging to certain fundamental dogma while revising others, he clearly risks satisfying no one by almost pleasing everyone.

In recent decades, the expansion of economic activity has been accompanied by negative environmental impacts. In response, there have been dramatic changes worldwide in terms of an increased demand for environmentally friendly products and services. To achieve these eco-innovations, firms have sought to acquire knowledge and implement operational flexibility by cooperating with different agents such as universities through a value cocreation system that is also expected to enhance firms’ performance. Using a sample of 250 companies, the present paper examines the (...) role of cooperation with universities in the development of diverse environmental innovations and building operational flexibility and, through this, improving firm performance. Results show that firms that value cooperation with universities develop a wider range of environmental innovations and increase their sales and benefits. (shrink)

Designated bishop of Silves, diocese of Faro, Algarve, in 1334, D. Alvaro Pelayo entered in conflict with Alfonso IV (1325-57), the King of Portugal, sending him two letters in that one can notice that there he also had to defend the jurisdictional autonomy of the spiritual power, in order to the centralizing politics that the king, following his father’s steps, D. Dinis (1279-1325), gave continuity, with the purpose of restricting the political space of the high Lusitanian clergy. Past some few (...) years, (1347) for the same reason, the conflict of the relationships of power among the two authorities increased. Our purpose here is double: to analyze the historical facts related with the two mentioned conflicts, well as the aspects doctrinal contents in the two referred letters, with view to show the thought coherence and attitude of D. Alvaro Pelayo. (shrink)

En el sexagésimo aniversario de la liberación del campo de exterminio de Auschwitz, el tema de la dialéctica de la Ilustración (que se situó en el núcleo del pensamiento crítico de posguerra), sigue siendo una cuestión abierta y candente. ¿Qué proceso de transformación atraviesa la visión del mundo occidental para que los valores de la Ilustración resulten de improviso completamente inoperantes para detener la expansión de la barbarie más antihumana? Este interrogante aún desafía la construcción de una cultura universalista a (...) partir de la tradición de la modernidad, moviéndonos a un replanteamiento crítico de su trayectoria.

El motivo central de la Teoría Crítica de la Escuela de Francfort fue el concepto de dialéctica de la Ilustración. Pero la amenaza de un mundo completamente administrado por el impulso de una racionalidad formal se vuelve asimismo hacia las instancias críticas: ¿dónde puede hallarse el criterio independiente capaz de desvelar, por contraste, la mecánica del avasallamiento total de la modernización? La Teoría Crítica lo buscó a la vez en el espíritu moral de una Ilustración humanista y en el horizonte (...) del movimiento comunista internacional liderado por la URSS. Esta balance se truncó trágicamente ante la evidencia de la "perversión soviética del contenido humano del socialismo revolucionario".

The synthesis of the Critical Theory’s called essentials shapes shows the remaining and relevance of the Enlightment Dialectic’s notion. With this we can notice the relation between productive rationalization and social relations’ instrumental deformation, as constitutive character of modern culture. At time, the dialectic nature of Enlightment’s categories propitiates a melting of critical theorizations engaged with reformulated Enlightments’s ideals. This dialectic establishes some epistemologic conditions for the restoration of Critical Theory’s posibilities conditions. Around these, we feel necessary a sistematic connection (...) among materialist and hermenutic attitude on the analysis of knowledge’s historic determination. Historic interest’s concept allows the elaboration of that alternative, opening ways of reflection to Critical Theory’s revolutionary restating. This objective requires the recovering of historic experience’s extreme notion, formulated by original project of that’s most significative authors. (shrink)

The practice of physical activity (PA) contributes to the prevention of chronic diseases such as obesity, metabolic syndrome or cardiovascular diseases, being also directly related to the individual’s physical fitness. Therefore, it is necessary to measure and monitoring the levels of PA in childhood and adolescence, since it may be useful to describe their current health status and the association with physical fitness, as well as to reveal putative consequences in the future. Within the educational field, it has been shown (...) that physical education (PE) classes are a favorable context for the creation of healthy physical-sports habits and self-determined motivation could be a key for explaining the level of PA practice. For this reason, the purpose of this research was to study the mediating role of integrated regulation (IR) on the relationship between PA and physical fitness in children and adolescents. A total of 325 students between 11 and 14 years old participated in the study. The level of PA was estimated through the specific Physical Activity Questionnaire for Children (PAQ-C), while motivation and IR were measured by using the Perceived Locus of Causality scale (PLOC-2). In addition, physical fitness was measured through the Eurofit fitness battery of tests, composed of three body composition measures and seven tests of different physical capacities. The physical fitness score showed no differences when genders were compared. After regression analysis, the resulti... (shrink)

This book focuses on a key issue today: the role of values in technology, with special emphasis on ethical values. This topic involves the analysis of internal values in technology (as they affect objectives, processes, and outcomes) and the study of external values in technology (social, cultural, economic, ecological, et cetera). These values - internal and external - are crucial to the decision making of engineers. In addition, they have increasing relevance for citizens concerned with the present and future state (...) of technology, which gives society a leading position in technological issues. The book follows three main lines of research: 1) new perspectives on technology, values, and ethics; 2) rationality and responsibility in technology; and 3) technology and risks. This volume analyzes the two main sides involved here: the theoretical basis for the role of values in technology and a practical discussion on how to implement them in our society. Thus, the book is of interest for philosophers, engineers, academics of different fields, and policy-makers. The style used lends itself to broad audience. (shrink)

The problem of the limits of science — of the “barriers” and the “confines” — requires a new analysis, which is the task of this book. The issue is considered from the perspective of science as a human activity.

The focus of this study was to analyze the content, distribution, and comparative genome relationships of 996 chromosome bin-mapped expressed sequence tags accounting for 2266 restriction fragments on the homoeologous group 3 chromosomes of hexaploid wheat. Of these loci, 634, 884, and 748 were mapped on chromosomes 3A, 3B, and 3D, respectively. The individual chromosome bin maps revealed bins with a high density of mapped ESTs in the distal region and bins of low density in the proximal region of the (...) chromosome arms, with the exception of 3DS and 3DL. These distributions were more localized on the higher-resolution group 3 consensus map with intermediate regions of high-mapped-EST density on both chromosome arms. Gene ontology classification of mapped ESTs was not significantly different for homoeologous group 3 chromosomes compared to the other groups. A combined analysis of the individual bin maps using 537 of the mapped ESTs revealed rearrangements between the group 3 chromosomes. Approximately 232 of the consensus mapped ESTs matched sequences on rice chromosome 1 and revealed large- and small-scale differences in gene order. Of the group 3 mapped EST unigenes ∼21 and 32% matched the Arabidopsis coding regions and proteins, respectively, but no chromosome-level gene order conservation was detected. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Form and Argument in Late Plato ed. by Christopher Gill and Mary Margaret McCabeFrancisco J. GonzalezChristopher Gill and Mary Margaret McCabe, editors. Form and Argument in Late Plato. Oxford: Oxford University Press, 1996. Pp. xi + 345. Cloth, $65.00.This collection has the commendable aim of challenging the view that in Plato’s “late” works the dialogue form is a mere formality adding little to the argumentative content, a view (...) still widespread among “analytic” scholars. The qualification is necessary because this view has already been seriously challenged by “nonanalytic” interpreters. It is therefore surprising that the editors chose contributors who almost all “share the analytic’ approach which is prominent in Anglo-American scholarship on Plato,” despite their admission that this approach has focused more on arguments than on the dialogue form (2, 299–300). Why seek to reinvent the wheel without the help of those who have already invented it? As a result, while the volume certainly makes an important contribution to our understanding of the form of this group of dialogues, it is much more successful in providing helpful and illuminating readings of their argumentative content: the detailed and rigorous analyses of McCabe, Malcolm Schofield (both on the Parmenides), and Gail Fine (on the Theaetetus) deserve special mention. The aim of the present review, which could not even begin to do justice to what the volume provides in the latter area, is therefore limited to documenting its mixed success in addressing some fundamental questions about form that have already occupied nonanalytic scholars (perhaps too exclusively):1) Does the main speaker speak for Plato?Given the great variety of main speakers in the “late” dialogues (Socrates, Parmenides, the Eleatic Stranger, Timaeus, the Athenian Stranger), each with a distinct personality and a distinct method, no attempt to understand the form of these dialogues should avoid this question. Gill raises it (293–95) and Schofield provides the most explicit response in denying that any interlocutor in a Platonic dialogue “can be assumed to be merely a spokesman for Plato’s own views” (51). More importantly, the essays by Dorothea Frede (on the Philebus) and Catherine Osborne (on the Timaeus), probably the most valuable in the volume, show what results can be achieved without this assumption. On the other hand, Michael Frede (on the Sophist) and Christopher Rowe (on the Politicus; see 158 and cf. 172 n.48) simply assume without argument that the Eleatic Stranger = Plato. All other contributors make the “spokesman” assumption, either implicitly or explicitly (see Christopher Bobonich’s reading of the Laws, 254–55).2) What is the significance of the dramatic context, especially dramatic chronology and characterization?As often noted, the Parmenides is set in Socrates’ youth and is in this sense the earliest [End Page 311] dialogue, while the series Theaetetus-Sophist-Politicus is set immediately before Socrates’ trial and condemnation. McCabe and Schofield are silent about the first fact. M. Frede briefly discusses the second (146–47), but adds little to what has already been said by others. As for the characterization of specific interlocutors, this volume overall has surprisingly little to offer. The essays of D. Frede and Osborne, however, are exemplary in this area.3) Why did Plato choose to write these works as dialogues rather than as treatises?Bobonich, D. Frede, and Osborne succeed in demonstrating the significance and even necessity of the dialogue form, an extraordinary achievement given the dialogues they discuss. Osborne in particular brilliantly shows how the dialogue form undercuts the common tendency to read the Timaeus as a treatise on natural science. Other contributors are less successful in answering this question central to the volume’s task. Schofield takes himself to be reading the Parmenides as a dialogue (51) because he, unlike Vlastos, interprets the Third Man Argument (second version) in the wider context of other arguments in the dialogue, including those of the second half. But “reading arguments in context” is demanded by any philosophical text and has nothing per se to do with the dialogue form. Fine reads the first part of the Theaetetus as the dialectical elaboration and refutation of an opponent’s view (109), but this could just as well be... (shrink)

The relation between Wittgenstein's philosophy of mathematics and mathematical Intuitionism has raised a considerable debate. My attempt is to analyse if there is a commitment in Wittgenstein to themes characteristic of the intuitionist movement in Mathematics and if that commitment is one important strain that runs through his Remarks on the foundations of mathematics. The intuitionistic themes to analyse in his philosophy of mathematics are: firstly, his attacks on the unrestricted use of the Law of Excluded Middle; secondly, his distrust (...) of non-constructive proofs; and thirdly, his impatience with the idea that mathematics stands in need of a foundation. These elements are Fogelin's starting point for the systematic reconstruction of Wittgenstein's conception of mathematics. (shrink)

The majority of antimicrobials that are produced are administered to animals, particularly food animals. While the overall impact of antimicrobial use in animals on antimicrobial resistance in humans and the environment is unclear, it undeniably has a role. Yet, some degree of antimicrobial use in animals is necessary for animal health and welfare purposes. Balancing the benefits and risks of antimicrobial use in animals is challenging because of the complexity of the problem and limitations in available data. However, a range (...) of measures can be implemented to reduce, refine and optimize antimicrobial use in animals, with a goal of minimizing the impact on human and environmental health while maintaining necessary therapeutic use in animals. A pandemic instrument can provide the necessary foundation for the whole-of-society and whole-of government One Health approach that is required to strengthen surveillance, communication, collaboration, and action.

Little is known about the impact of context on the meaning of emotion words. In the present study, we used a semantic profiling instrument to investigate features representing five emotion components of 11 emotion words in situational contexts involving success or failure. We compared these to the data from an earlier study in which participants evaluated the typicality of features out of context. Profile analyses identified features for which typicality changed as a function of context for all emotion words, except (...) contentment, with appraisal features being most frequently affected. Those context effects occurred for both hypothesised basic and non-basic emotion words. Moreover, both data sets revealed a four-dimensional structure. The four dimensions were largely similar. The results suggest that context may not change the underlying dimensionality but affects facets of the meaning of emotion words. (shrink)

The objective of this research is to develop accurate forecasting models for chlorophyll-α concentrations at various depths in El Mar Menor, Spain. Chlorophyll-α plays a crucial role in assessing eutrophication in this vulnerable ecosystem. To achieve this objective, various deep learning forecasting techniques, including long short-term memory, bidirectional long short-term memory and gated recurrent uni networks, were utilized. The models were designed to forecast the chlorophyll-α levels with a 2-week prediction horizon. To enhance the models’ accuracy, a sliding window method (...) combined with a blocked cross-validation procedure for time series was also applied to these techniques. Two input strategies were also tested in this approach: using only chlorophyll-α time series and incorporating exogenous variables. The proposed approach significantly improved the accuracy of the predictive models, no matter the forecasting technique employed. Results were remarkable, with |$\overline{\sigma}$| values reaching approximately 0.90 for the 0.5-m depth level and 0.80 for deeper levels. The proposed forecasting models and methodologies have great potential for predicting eutrophication episodes and acting as decision-making tools for environmental agencies. Accurate prediction of eutrophication episodes through these models could allow for proactive measures to be implemented, resulting in improved environmental management and the preservation of the ecosystem.

The amount of information that is produced on a daily basis in the financial markets is vast and complex; consequently, the development of systems that simplify decision-making is an essential endeavor. In this article, several intelligent systems are proposed and tested to predict the closing price of the IBEX 35 index using more than ten years of historical data and five distinct architectures for neural networks. A multi-layer perceptron was the first step, followed by a simple recurrent neural network, a (...) gated recurrent unit network and two long-short-term memory (LSTM) networks. The results of the analyses performed on these models have demonstrated a powerful capacity for prediction. Additionally, the findings of this research point to the fact that the application of intelligent systems can simplify the decision-making process in financial markets, which is a substantial advantage. Furthermore, by comparing the predicted outcome errors between the models, the LSTM presents the lowest error with a higher computational time in the training phase. The LSTM was able to accurately forecast the closing price of the day as well as the price for the following one and two days in advance. In conclusion, the empirical results demonstrated that these models could accurately predict financial data for trading purposes and that the application of intelligent systems, such as the LSTM network, represents a promising advancement in financial technology.

Food choices are a key determinant of dietary intake, with brain regions, such as the mesolimbic and prefrontal cortex maturing at differential rates into adulthood. More needs to be understood about developmental changes in healthy and unhealthy food perceptions and preference. We investigated how food perceptions and preference vary as a function of age and how food attributes impact age-related changes. One hundred thirty-nine participants completed computerized tasks to rate high-calorie and low-calorie food cues for taste, health, and liking, followed (...) by 100 binary food choices based on each participant’s ratings. Dietary self-control was considered successful when the healthier food was chosen. Self-control success ratio was the proportion of success trials over total number of choices. Beta-weights for health and taste were calculated as each attribute’s influence on food preference. Adiposity measurements included BMI z-score and waist-to-height ratio. High-calorie foods were rated more tasty and less healthy with increasing age. Older participants liked high-calorie foods more, and β-taste was associated with age. Significant age-by-WHtR interactions were observed for health and taste ratings of high-calorie foods, β-taste, and marginally for preference of high-calorie foods. Stratifying by WHtR, we found age-related increases in taste and preference ratings of high-calorie foods in the high WHtR group alone. In contrast, age-related decreases in health ratings of high-calorie foods were significant in the low WHtR group alone. Age and β-taste were significantly associated in the high WHtR group and only marginally significant with low WHtR. Although participants rated low-calorie foods as less tasty and less healthy with increasing age, there was no association between age and preference for low-calorie foods. Participants made faster food choices with increasing age regardless of WHtR, with a significant age-by-WHtR interaction on reaction time. There were no age-related effects in self-control success ratio and β-health. These results suggest that individual differences in age and central adiposity play an important role in preference for high-calorie foods, and a higher importance of food tastiness in food choice may contribute to greater preference for high-calorie foods with increasing age.

In this paper, we address the question whether a mechanistic approach can account for evolutionary causes. The last decade has seen a major attempt to account for natural selection as a mechanism. Nevertheless, we stress the relevance of broadening the debate by including the other evolutionary causes inside the mechanistic approach, in order to be a legitimate conceptual framework on the same footing as other approaches to evolutionary theory. We analyse the current debate on natural selection as a mechanism, and (...) extend it to the rest of the evolutionary causes. We focus on three approaches that we call the stochastic view, the functional view, and the minimalist view. We argue that all of them are unable to account for evolutionary causes as mechanisms. It is concluded that the current mechanistic proposals cannot be accepted as a common framework for evolutionary causes. Finally, we outline some guidelines and requirements that any mechanistic proposal should meet in order to be applied to evolutionary theory. (shrink)
