Dancing with eyes wide open: On the role of nostalgia in education

Nostalgia rightly elicits suspicion, even derision, for to give oneself up to longing for something from the past runs the risk of compromising one's capacity to act effectively in the present. But this does not make nostalgia, by definition, either sentimentally reactionary or wistfully unreflective. On the contrary, in the education context and elsewhere, it can be the exact opposite, though its influence, which is legitimate, particularly when articulated through the optic of tradition, needs to be constrained and justified by good argument and, where relevant, sound empirical research

Ball Bearing Analysis with the ORBIS Tool

Ball bearing design is critical to the success of aerospace mechanisms. Key bearing performance parameters, such as load capability, stiffness, torque, and life all depend on accurate determination of the internal load distribution. Hence, a good analytical bearing tool that provides both comprehensive capabilities and reliable results becomes a significant asset to the engineer. This paper introduces the ORBIS bearing tool. A discussion of key modeling assumptions and a technical overview is provided. Numerous validation studies and case studies using the ORBIS tool are presented. All results suggest the ORBIS code closely correlates to predictions on bearing internal load distributions, stiffness, deflection and stresses

Singularities of the renormalization group flow for random elastic manifolds

We consider the singularities of the zero temperature renormalization group flow for random elastic manifolds. When starting from small scales, this flow goes through two particular points $l^{*}$ and $l_{c}$, where the average value of the random squared potential turnes negative ($l^{*}$) and where the fourth derivative of the potential correlator becomes infinite at the origin ($l_{c}$). The latter point sets the scale where simple perturbation theory breaks down as a consequence of the competition between many metastable states. We show that under physically well defined circumstances $l_{c} to negative values does not take place.Comment: RevTeX, 3 page

Critical incidents in a forensic psychiatric population: An exploratory study of motivational factors

This exploratory study examined the motivations for forensic clients’ engagement in critical incidents, specifically hostage-taking, barricades and roof-top protests. Using thematic analysis, a range of themes were identified. These included engaging in such incidents to seek deliberate isolation from others, gaining control, getting their needs meet, a need to communicate and being influenced by their peers. Selection of potential hostages appeared linked to feeling of grievance towards them. Yet the distress of a hostage, along with consideration as to the longer term consequences of their actions both for themselves and morally, appeared to reduce the risk of engagement in such incidents. The results are discussed in terms of Individualism, Self-Determination Theory of Motivation and Maslow’s Hierarchy of Human Needs

An Exactly Solved Model of Three Dimensional Surface Growth in the Anisotropic KPZ Regime

We generalize the surface growth model of Gates and Westcott to arbitrary inclination. The exact steady growth velocity is of saddle type with principal curvatures of opposite sign. According to Wolf this implies logarithmic height correlations, which we prove by mapping the steady state of the surface to world lines of free fermions with chiral boundary conditions.Comment: 9 pages, REVTEX, epsf, 3 postscript figures, submitted to J.
