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

Gravitational collapse of massless scalar field in f(R) gravity
No full textWe study the spherically symmetric gravitational collapse of massless scalar matter field in asymptotic flat spacetime in the Starobinsky R-2 gravity, one specific model in the f(R) gravity. In the Einstein frame of f(R) gravity, an additional scalar field arises due to the conformal transformation. We find that in addition to the usual competition between gravitational energy and kinetic energy in the process of gravitational collapse, the new scalar field brought by the conformal transformation adds one more competing force in the dynamical system. The dynamical competition can be controlled by tuning the amplitudes of the initial perturbations of the new scalar field and the matter field. To understand the physical reasons behind these phenomena, we analyze the gravitational potential behavior and calculate the Ricci scalar at center with the change of initial amplitudes of perturbations. We find rich physics on the formation of black holes through gravitational collapse in f(R) gravity.NNSF of ChinaSCI(E)[email protected]; [email protected]; [email protected]
Bianchi type-I universe in f(R, T) modified gravity with quark matter and Λ
No full text32nd International Physics Congress of Turkish-Physical-Society (TPS) -- SEP 06-09, 2016 -- Bodrum, TURKEYIn this study, we investigate homogeneous and anisotropic Bianchi type I universe in the presence of quark matter source in f (R, T) gravity (Harko et al. in Phys. Rev. D 84:024020, 2011) with cosmological constant A (where R is the Ricci scalar and T is the trace of the energy momentum tensor). For this aim we have used the anisotropy feature of Bianchi type I universe and equation of states (EoS) of quark matter. We explore the exact solution f(R, T)=R + 2f(T) model for Bianchi type I universe model. When t -> infinity, we get very small cosmological constant value, this result agrees with recent observations.Turkish Phys So
Singularity problem in the f(R) model with nonminimal coupling
No full textWe consider the nonminimal coupling between matter and the geometry in the f(R) theory. In the new theory which we established, a new scalar psi has been defined and we give it a certain stability condition. We intend to take a closer look at the dark energy oscillating behavior in the de Sitter universe and the matter era, from which we derive the oscillating frequency and the oscillating condition. More importantly, we present the condition of coupling form that the singularity can be solved. We discuss several specific coupling forms and find that logarithmic coupling with an oscillating period Delta T similar to Delta z in the matter era z > 4 can improve singularity in the early universe. The result of numerical calculation verifies our theoretic calculation about the oscillating frequency. Considering two toy models, we find the cosmic evolution in the coupling model is nearly the same as that in the normal f(R) theory when lna > 4. We also discuss the local tests of the nonminimal coupling f(R) model and show the constraint on the coupling form.
