George Argyros, Betty Hutton Williams, and G. T. "Buck" Smith at the dedication of Hutton Sports Center, 219 E. Sycamore St., Chapman College, Orange, California, on Founders' Day, November 10, 1979. The Harold Hutton Sports Center, completed in 1978, is named in honor of this former trustee, and made possible by a gift from his widow, Betty Hutton Williams.

La educación en las novelas de Jean Marie de Buck.

Estudiar en las obras 'Dios hablará esta noche' y 'El silencio de un adolescente' de Jean Marie de Buck. Las principales ideas pedagógicas contenidas en estas novelas se reducen a: realismo pedagógico. El educando tiene múltiples posibilidades y la educación actuando sobre ellas produce resultados positivos. Por estos motivos, hay que mantener en el adolescente un alto nivel de exigencia en los aspectos personal, social y trascendente. La educación es una obra que se tiene que llevar a cabo en común entre el educando y los distintos educadores que le ayudan. Dios habla a través de las personas, de las cosas de los acontecimientos. Hay que fomentar en el educando una disposición de apertura al mensaje que se le dirige y que únicamente él puede realizar.

Pedagogía de J. M. de Buck.

Señalar que J. M. de Buck en su vida y en su obra es un auténtico pedagogo. El autor hace una critica bastante dura de la burguesia, presenta una burguesia que teme el esfuerzo físico, que abusa de la comodidad, que no sabe adaptarse a una ley de acción y que vive refugiado en su orgullo de casta. En esto mismo algunas veces se contradice, en su novela 'Dios hablará esta noche' demuestra lo contrario, comprobamos que no todos estos chicos carecen de carácter y de dominio. Subraya la importancia de la formación de los padres. Se excede quizá al acusarlos siempre de ser la causa de los fracasos. Trata bastante superficial lo referente al adolescente en su evolución, no puntualiza bien. Pasa por alto la educación sexual, siendo uno de los problemas que presentan mayor dificultad a esta edad. La educación estética, aunque no la estudia por separado, la encontramos a lo largo de toda la novela, de manera especial en 'Dios hablará esta noche'. Aunque su obra no es un tratado cientifico su pedagogía convence porque está al alcance de todos, es sencilla y facilmente aplicable. Insiste en la importancia de una buena educación inicial, de donde se deduce la necesidad de formación en los padres. El factor determinante principal es el ambiente familiar. La familia es la que consolida y complementa la inteligencia y todo cuanto de social hay en la educación. Se nota la importancia que da a la educación social en la adolescencia. En cuanto al educador señala como indispensable el principio del ser. Para educar no basta saber, es necesario ante todo ser. Interés del método psicopedagogico y de la necesidad del médico para la educación no sólo de anormales sino también de los normales. Insiste en la educación positiva más que represiva: em la política de relación y de persuasión para dirigir al adolescente.

Dancy on buck passing

I defend the buck-passing account of value from Dancy's critique.

New tools to boost butterfly habitat quality in existing grass buffer strips

There are approximately 29,000 ha of grass buffer strips in the UK under Agri-Environment Schemes; however, typically they are floristically poor and as such are of limited biodiversity value. Introducing a sown wildflower component has the potential to increase dramatically the value of these buffer strips for a suite of native species, including butterflies. This study investigates management practices aiming to promote the establishment and maintenance of wildflowers in existing buffer strips. The effectiveness of two methods used to increase the establishment of wildflowers for the benefit of native butterfly species were tested, both individually and in combination. The management practices were: (1) the application of a selective graminicide (fluazifop-P-butyl) which reduces the dominance of competitive grasses; and (2) scarification of the soil which creates germination niches for sown wildflower seeds. A wildflower seed mix consisting of nine species was sown in conjunction with the scarification treatment. Responses of wildflowers and butterflies were monitored for two years after establishment. Results indicate that the combined scarification and graminicide treatment produced the greatest cover and species richness of sown wildflowers. Butterfly abundance, species richness and diversity were positively correlated with sown wildflower species richness, with the highest values in the combined scarification and graminicide treatment. These findings have confirmed the importance of both scarification as a means of introducing wildflower seed into existing buffer strips, and subsequent management using graminicides, for the benefit of butterflies. Application of this approach could provide tools to help butterfly conservation on farmland in the future.

A comparison between bond graphs switching modelling techniques implemented on a boost dc-dc converter

A Bond Graph is a graphical modelling technique that allows the representation of energy flow between the components of a system. When used to model power electronic systems, it is necessary to incorporate bond graph elements to represent a switch. In this paper, three different methods of modelling switching devices are compared and contrasted: the Modulated Transformer with a binary modulation ratio (MTF), the ideal switch element, and the Switched Power Junction (SPJ) method. These three methods are used to model a dc-dc Boost converter and then run simulations in MATLAB/SIMULINK. To provide a reference to compare results, the converter is also simulated using PSPICE. Both quantitative and qualitative comparisons are made to determine the suitability of each of the three Bond Graph switch models in specific power electronics applications

Bond graph models of DC-DC converters operating in both CCM and DCM

In this paper, Bond Graphs are employed to develop a novel mathematical model of conventional switched-mode DC-DC converters valid for both continuous and discontinuous conduction modes. A unique causality bond graph model of hybrid models is suggested with the operation of the switch and the diode to be represented by a Modulated Transformer with a binary input and a resistor with fixed conductance causality. The operation of the diode is controlled using an if-then function within the model. The extracted hybrid model is implemented on a Boost and Buck converter with their operations to change from CCM to DCM and to return to CCM. The vector fields of the models show validity in a wide operation area and comparison with the simulation of the converters using PSPICE reveals high accuracy of the proposed model, with the Normalised Root Means Square Error and the Maximum Absolute Error remaining adequately low. The model is also experimentally tested on a Buck topology.

The buck passing account of value: assessing the negative thesis

The buck-passing account of value involves a positive and a negative claim. The positive claim is that to be good is to have reasons for a pro-attitude. The negative claim is that goodness itself is not a reason for a pro-attitude. Unlike Scanlon, Parfit rejects the negative claim. He maintains that goodness is reason-providing, but that the reason provided is not an additional reason, additional, that is, to the reason provided by the good-making property. I consider various ways in which this may be understood and reject all of them. So I conclude that buck-passers cannot reject the negative claim.
