Behaviour of sandy soil subjected to dynamic loading

This thesis presents the kinematics occurring during lab-based dynamic compaction tests using high speed photography and image correlation techniques. High speed photography and X-ray microtomography have been used to analyse the behaviour of sandy soil subjected to dynamic impact. In particular, the densification mechanism of granular soils due to dynamic compaction is the main theme of the thesis. High speed photography and digital image correlation (DIC) techniques have enabled the deformation patterns, soil strains and strain localisations to be observed. Image correlation and X-ray scans revealed the formation, rate and growth of narrow tabular bands of intense deformation and significant volumetric change and provided answers towards a better understanding of the densification mechanism in dry granular soils due to dynamic compaction. As a quantitative tool, high speed photography has allowed the propagation of localised deformation and strain fields to be identified and has suggested that compaction shock bands control the kinematics of dynamic compaction. The displacement and strain results from high speed photography showed that soil deformation in the dynamic tests was dominated by a general bearing capacity mechanism similar to that widely stated in classic soil mechanics texts. Comparative static loading tests have been conducted to enable the dynamic effects to be clearly distinguished. This has enabled the densification process taking place below the soil surface to be investigated and identified. Simulations of the physical models were carried out using LS-DYNA finite element formulations for comparison and verification purposes. The FE simulations verified the general characteristics from the photography findings. However, simulation results were unable to predict the exact details of the strain localisation due to surface impacts during physical model tests

Being Political in German Theatre and Performance: Anna Langhoff and Christoph Schingensief

Anna Langhoff and Christoph Schlingensief are two contemporary theatre makers who sit at opposite ends of the dramatic/postdramatic theatre divide. In that both artists see themselves as critics of western neoliberalism, their different approaches to theatre and performance invite a comparative study of ‘being political’. Langhoff’s neorealist plays and Schlingensief’s performance events both demonstrate the limits of liberal society’s capacity to deal with complex social problems. But how effective is each after the event? The paper uses Han Thiess Lehmann’s study of postdramatic theatre to compare the two performance styles.The conference was sponsored by A.D.S.A., the Department of Performance Studies, the School of Letters, Arts and Media, and the Faculty of Arts of the University of Sydney

Lifespan development of personality and developmental outcome domains: A commentary

Item does not contain fulltextCommenting on the papers of this special issue, an evolutionary and lifespan perspective was taken. A model was proposed of parallels in the trajectories of the development of personality and developmental outcome domains across the life course. Despite findings of mean-level change in personality development, the hypothesis was propagated of absence of normative change in personality development and developmental outcome domains across the life course, combined with the preservation of stable individual differences for the majority of people and unstable individual differences for minorities. The role of the role of personality in psychological processes involved in problem solving on developmental outcome domains needs further systematic study.10 p

Life-span personality development: Goal-oriented agents and developmental outcome

Several historical trends are enumerated that preceded contemporary discussions concerning the development of personality dimensions, personality types, and the person as a self-organising goaloriented agent. For description of personality across the life course, the big- ve personality dimensions are related to similar dimensions in temperament. For a proper understanding of the person as an active agent in personality development, amodel for personality functioning is proposed that integrates elements of descriptive research on personality and temperament with theoretical views on personality and temperament functioning, that is, Block and Block’s (1980) views on the curvilinear relation between ego-control and ego-resiliency and Rothbart’s (1989) ideas on the distinction between reactivity and self-regulation. Typological personality studies are related to this model for personality functioning. Finally, personality development across the life course is related to the development of four developmental domains (i.e., interpersonal, achievement, self-concept, and creative domains)
