Application of a new sensory-instrumental tool for the evaluation of promising apple genotypes
No full textMost frequently, breeding programs adopt instrumental evaluation methods to assess the quality of the selections of interest. Sensory methods, when applied, are employed only at a later stage on fruit of selection chosen on the basis of previous instrumental screenings. Instrumental measurements, however, cannot replace sensory evaluation when a description of perceivable quality is needed. In this work, a detailed protocol, combining sensory and instrumental methods, is applied to define the sensory properties of 11 new apple breeding selections (Malus × domestica Borkh.) and to characterise them from their original parental genotypes. The final aim is to provide to breeders a reliable sensory profile of new selections, and a useful tool to predict sensory properties by instrumental characterisation. Descriptive sensory analysis was performed by a trained sensory panel of 14 judges through a sensory vocabulary composed of 11 attributes related to texture, taste and overall odour and flavour [1]. Simultaneously on the same samples the basic chemical composition and texture properties were assessed by a set of standard and innovative instrumental measurements [2], to allow the interpretation of the sensory description in terms of fruit chemical and physical properties. The collected data permitted to study affinities and specificities of the new selections in comparison to their parental genotypes. Instrumental measurements confirmed the existence of differences between the samples and reflected their sensory description, helping to interpret the perceivable quality in terms of chemical and physical properties. Moreover, the combined analyses allowed the development of effective prediction models, with very good results especially for the texture attributes. This is an important first step in the achievement of a reliable complete sensotyping of apples by rapid instrumental characterisation that can be applied on the large data sets usually needed in the initial phase of breeding programs.

F. R. Leavis: The Creative University
No full textThis is a critical introduction to the educational thought of F. R. Leavis (1895-1978), the greatest English literary critic of the twentieth century, providing the first in-depth examination of Leavis's ideas in relation to contemporary mass higher education. During the course of a long, prolific and controversial academic career, which saw him take issue with figures such as Wittgenstein, T. S. Eliot and C. P. Snow, Leavis became one of the most articulate advocates for the idea of the university as 'a centre of consciousness and human responsibility' in the face of what he saw as the relentless technological drive of civilisation. With the journal Scrutiny which he co-founded, as well as his critical writings, Leavis became a decisive influence on generations of teachers in Britain and overseas. Widely misrepresented as narrowly elitist, his ideas about 'the creative university', with their radical, student-centred approach to teaching, constitute a powerful resource for a higher education system grappling with the contradictory demands of continuity and change. Based on original research, the study provides an overview of Leavis's life, work and heritage and his educational world view, and a comprehensive exploration of Leavis's pedagogy from theoretical and practical perspectives. It also includes a first-hand account by the author of being taught by Leavis in person
