El cine, ¿puede hacernos peores? Stanley Cavell y el perfeccionismo moral
2016
El filósofo norteamericano S. Cavell ha estudiado los vínculos entre el cine clásico hollywoodense y el perfeccionismo moral emersoniano. Se ofrece una exposición tanto de los presupuestos que este pensador asume en su análisis del fenómeno cinematográfico como del perfeccionismo moral que reivindica, encuadrándolos en el contexto teórico que les da sentido y sugiriendo algunas vías de crítica.
Essays on wages, promotions and performance evaluations
2017
This dissertation comprises four empirical research articles that use personnel data from a large university and worker-level panel data from Finland to examine the determinants of wages, promotions and employee performance evaluations. The first article employs personnel data to examine the importance of worker output and job seniority as predictors of employee performance evaluations and promotions. The results suggest that better-performing employees – with output measured both in absolute terms and relative to peers – were more likely to be assigned higher performance grades and had a higher probability of being promoted to more complex jobs than their peers with similar characteristics…
Alternative analysis of transient infiltration experiment to estimate soil water repellency
2019
The repellency index (RI) defined as the adjusted ratio between soil‐ethanol, Se, and soil‐water, Sw, sorptivities estimated from minidisk infiltrometer experiments has been used instead of the widely used water drop penetration time and molarity of ethanol drop tests to assess soil water repellency. However, sorptivity calculated by the usual early‐time infiltration equation may be overestimated as the effects of gravity and lateral capillary are neglected. With the aim to establish the best applicative procedure to assess RI, different approaches to estimate Se and Sw were compared that make use of both the early‐time infiltration equation (namely, the 1 min, S1, and the short‐time linear…
Development of an immunochromatographic assay based on carbon nanoparticles for the determination of the phytoregulator forchlorfenuron
2013
Rapid analytical methods enabling the determination of diverse targets are essential in a number of research areas, from clinical diagnostics to feed and food quality and safety. Herein, the development of a quantitative immunochromatographic assay for the detection of the synthetic phytoregulator forchlorfenuron (CPPU) is described. The competitive lateral flow immunoassay (LFIA) was based on the immobilization onto a nitrocellulose membrane of an ovalbumin-CPPU conjugate (test line) and on the use of an immunodetection ligand consisting of carbon nanoparticles labeled with an anti-CPPU monoclonal antibody through interaction with a secondary antibody. The presence of CPPU in horticultural…
Transformations Accompanying a Shift from Surface to Drip Irrigation in the Cànyoles Watershed, Valencia, Spain
2017
Drip irrigation is widely promoted in Spain to increase agricultural production and to save water. In the Cànyoles watershed, Valencia, we analysed the consequences of change from surface irrigation to drip irrigation over the past 25 years. There were a number of transformations resulting from, or accelerated by, this change including the 1) intensification of well construction causing a redistribution in access to groundwater, water shortages and a lowering of the groundwater table; 2) expansion of irrigation into former rain-dependent uphill areas resulting in increased water use; 3) shift to higher- value monoculture fruit crops, but with associated higher crop water requirements; 4) in…
Sociedad, Estado y Derecho en la tradición de pensamiento dialéctico
2006
Esta investigación es un síntesis de los elementos más importantes que podemos encontrar en la llamada "tradición de la escuela dialéctica". Comenzamos con una explicación de "la filosofía del Derecho" de GWF Hegel y, a continuación exponemos la contraposición de puntos de vista de la visión del Estado por parte de K. Marx(Idealismo vs. Materialismo). En el segundo capítulo, el tema es la recepción que ha efectuado la marxista "Escuela de Frankfurt" de la política y las teorías sociológicas de M. Weber. Finalmente, exponemos de manera breve la teoría sobre el Estado moderno de J. Habermas, que trata de dar una solución a los problemas de la modernidad apuntados por los autores "Escuela de F…
Una metafísica del ser en cuanto creación. Juan David García Bacca lee a Alfred North Whitehead
2017
Al considerar el tratamiento que realiza Juan David García Bacca de Process and Reality de Alfred North Whitehead, el articulo busca apreciar la afinidad entre ambos autores en su caracterización de las deficiencias de la ontología clásica y en su invención de conceptos para un nuevo enfoque de la ontología; a saber, una metafísica de la creación y la novedad.
Flexible and Efficient Computer-Aided Design Tool for Advanced Comb-Line Rectangular Waveguide Filters
2015
A very flexible and efficient computer-aided design (CAD) tool, specifically suited for advanced comb-line rectangular waveguide filters, is presented in this work. The developed software tool, which makes use of a full-wave analysis technique based on the Boundary Integral - Resonant Mode Expansion method, permits to load the considered comb-line resonators with any number of radially symmetrical partial-height metallic posts. The implemented CAD tool also allows for dealing with coupling windows of arbitrary cross-section, thus drastically enhancing the flexibility of the computer-aided design process. The excitation of the analyzed components, which is performed by using generalized coax…
O stawaniu się (o)sobą na drodze przezwyciężania samego siebie. Projekt radykalnej antropologii (neo)coachingowej
2020
Współczesny coaching dość dobrze sprawdza się w praktyce wychowawczej i terapeutycznej, ale brakuje mu solidnego fundamentu antropologicznego, to znaczy takiej koncepcji człowieka, która mogłaby stać się podstawą konstruktywnego (samo)rozwoju w duchu autentycznej wolności. Wydaje się, że w teorii coachingowej warto posłużyć się stworzoną przez Fryderyka Nietzschego koncepcją nadczłowieka. Oczekiwany przez Zaratustrę-Nietzschego nadczłowiek jest człowiekiem, który przezwyciężył własne słabości i potrafi twórczo działać w świecie, kierując się poczuciem odpowiedzialności za Ziemię. Korzystając z tej koncepcji (nad)człowieka, coach mógłby skutecznie pomagać swym podopiecznym i wychowywać ich „…
Practice for determining friction in hydraulic winch systems
2020
This paper presents a method for estimating friction in hydraulic active heave compensated (AHC) offshore winches. The method is a two-step approach where the first step is to model the friction loss in the hydraulic motors based on data from the sub-supplier. The second step requires real-life testing, where the remaining friction losses in the winch system is identified and modeled. In this context, a practice is characterized by obtaining a friction loss estimation with the highest possible accuracy over the widest possible range of operating conditions with a limited amount of experimental work. The method benefits from the use of parametric models, sub-supplier data, and real-life meas…
