Why the binding theory doesn’t apply at LF
No full textThis article argues that the relegation of the binding theory to the C-I interface (LF) is theoretically undesirable and empirically unwarranted. Recent Minimalist research has sought to eliminate the binding theory from UG by reducing its conditions to narrow-syntactic operations (Hornstein 2000, 2006; Reuland 2001, 2006; Kayne 2002; Zwart 2002, 2006; Hicks 2006). This approach remains controversial since the canonical Minimalist binding theory (Chomsky 1993; Chomsky and Lasnik 1993) views the binding conditions as interpretive rules applying at LF, supported by evidence that Condition A interacts with other interpretive phenomena assumed to be determined at LF (Lebeaux 1998; Fox and Nissenbaum 2004). While the interaction of anaphor binding and scope relations in particular is not disputed, I show that it is attributable to factors outside the binding theory, namely the requirement that variables (including anaphors) must be c-commanded by their binders at LF. Deprived of its strongest empirical argument, the LF binding theory can then be picked apart

LF-copying without LF
No full textAbstractA copying approach to ellipsis is presented, whereby the locus of copying is not a level of derived syntactic structure (LF), but rather the derivation itself. The ban on preposition stranding in sprouting follows without further stipulation, and other, seemingly structure sensitive, empirical generalizations about elliptical constructions, including the preposition stranding generalization, follow naturally as well. Destructive operations which ‘repair’ non-identical antecedents are recast in terms of exact identity of derivations with parameters. In the context of a compositional semantic interpretation scheme, the derivational copying approach to ellipsis presented here is revealed to be a particular instance of a proform theory, thus showing that the distinctions between, and arguments about, syntactic and semantic theories of ellipsis need to be revisited
Analysis of the psychometric properties of the spanish version of the diabetes empowerment scale (des-lf-s)
No full textThe purpose of this research was to analyze the psychometric properties of Anderson, Funnell, Fitzgerald y Marrero´s Diabetes Empowerment Scale, Long Form-Spanish (DES-LF-S), in 528 diabetic adults. The confirmatory factor analysis stated that the model that best adjust to the data has a tridimensional structure and replicates the structure of the scale in its original version. Items of the scale explained 63.79% of variance. The scale showed satisfactory levels of internal consistency, obtaining a Cronbach´s Alpha of .96; additionally percentiles for the interpretation of individual results were obtained. These findings support the use of DES-LF-S to evaluate self-efficacy related to diabetes in adults

El análisis factorial confirmatorio revela que el modelo que mejor se ajusta a los datos en la muestra tiene una estructura de 3 factores y replica la estructura de la escala en su versión original. Los reactivos que componen la escala explicaron el 63.79% de la varianza. La escala demostró niveles satisfactorios de consistencia interna, obteniéndose un alfa de Cronbach de .96; adicionalmente se obtuvieron los percentiles para la interpretación de resultados individuales. Los hallazgos apoyan el uso de la DES-LF-S para evaluar la autoeficacia relacionada con la diabetes en adultos con la enfermedad

Machine learning and digital twins: monitoring and control for dynamic security in power systems
No full textThe reader of the chapter will be able to connect techniques from machine learning (ML) and digital twins (DTs) to gain insights for monitoring and control of (dynamic) security for electrical power systems. DTs are validated and verified high-fidelity (hf) models providing high simulation accuracy. DTs can be used for simulation of the supervised process of system operation and are therefore able to provide synthetic studied data, where measurement data are scarce. However, for some real-time applications in monitoring and control, such high-fidelity simulation models are not appropriate due to the corresponding computational barrier. There, ML aims to create an application-specific, low-fidelity (lf) approximation of the digital twin. Such trained lf models are used in real-time applications where computational time is scarce and lf information is sufficient. The conceptual intersection of hf and lf models has been little explored and becomes increasingly complex. This chapter aims to provide a conceptual overview of how such hf and lf models can be combined. This chapter is split into two parts where the first part is to introduce ML, lf models, and digital twins, hf models, for power systems analysis, and the second chapter is to use these two types of models to form purpose-driven surrogate lf models, illustrated on the example of dynamic security assessment (DSA). In the first part, the concepts for using DTs as hf models for online power system studies and their corresponding tuning of model parameters are introduced. Subsequently, ML i.e., lf models, are introduced and their corresponding training frameworks.

Mejoramiento de la percolabilidad con el uso del Kollasol stg lf y la recuperación de oro en la Unidad Minera Pucamarca - Minsur - Tacna
No full textEl objetivo del presente estudio es mejorar la percolabilidad (permeabilidad) del lixiviante con el uso del Kollasol STG LF para la mejora de extracción de oro en la unidad minera Pucamarca-MINSUR, de utilidad para procesar mineral de sílice granular alterada. Se desarrolló una investigación de enfoque cuantitativo, aplicada y transversal de diseño explicativa experimental para muestras obtenidas por cuarteo sucesivo de 100 kg. Para medir su efectividad se consideró el consumo de surfactante, el consumo de cianuro y el porcentaje de extracción de oro. Las pruebas se realizaron haciendo un comparativo entre las pruebas en columna estándar y pruebas en columna con el tensoactivo kollasol STG LF. Los resultados de las pruebas del laboratorio realizado en columnas, muestran que con la adición de 32 ppm del tensioactivo Kollasol STG LF alcanza un incremento de 7,80 % de extracción de oro mayor a la prueba convencional, concluyéndose que el uso del KOLLASOL TG LF se logra incrementar la extracción de oro y reducir el tiempo de lixiviación al incrementar la cinética de lixiviación realizada a nivel de Laboratorio Metalúrgico.Tesi
