Shape of matchbox manifolds

In this work, we develop shape expansions of minimal matchbox manifolds without holonomy, in terms of branched manifolds formed from their leaves. Our approach is based on the method of coding the holonomy groups for the foliated spaces, to define leafwise regions which are transversely stable and are adapted to the foliation dynamics. Approximations are obtained by collapsing appropriately chosen neighborhoods onto these regions along a "transverse Cantor foliation". The existence of the "transverse Cantor foliation" allows us to generalize standard techniques known for Euclidean and fibered cases to arbitrary matchbox manifolds with Riemannian leaf geometry and without holonomy. The transverse Cantor foliations used here are constructed by purely intrinsic and topological means, as we do not assume that our matchbox manifolds are embedded into a smooth foliated manifold, or a smooth manifold.Comment: 36 pages.

The Retirement Expectations of Middle-Aged Individuals

We use the first three waves of the Household Income and Labour Dynamics in Australia (HILDA) Survey to examine the retirement plans of middle-aged workers (aged 45-55). Our results indicate that approximately two-thirds of men and more then half of women appear to be making standard retirement plans. At the same time, more than one in five individuals seem to have delayed their retirement planning and approximately one in ten either do not know when they expect to retire or expect to never retire. Retirement plans are closely related to current labor market position. Specifically, forming expectations about the age at which one will leave the labor market appears to be easier for workers in jobs with well defined pension benefits and standard retirement ages. Moreover, those who report that they do not know when they expect to retire do in fact appear to face greater uncertainty in their retirement planning. Those who anticipate working forever seem to do so out of concerns about the adequacy of their retirement incomes rather than out of increased job satisfaction or a heightened desire to remain employed. Finally, men alter their retirement plans in response to labor market shocks, while women are more sensitive to their own and their partners’ health changes.retirement, expectations, middle-aged workers

What happens to travel behaviour when the right to park is removed?

© 2018 Elsevier Ltd What happens to travel behaviour when the right to park at a destination is removed? This question, fundamental to travel demand management and land-use planning, has only been partially addressed in the literature so far. The impacts on travel to the destination concerned have been studied, but not the impacts on wider travel behaviour. This paper reports on a natural experiment related to destination parking, where a university removed the right of most undergraduates living off-campus to park on its main suburban campus. A survey was conducted to compare the travel behaviours of two groups of undergraduate students: the first group started before and the second group started after the introduction of the parking restriction (n = 858). The survey captured licence-holding, car availability during the term and vacation periods, and the mode of transport used to travel to campus and for the last trip to another location. The parking restriction was associated with a fall in the modal share of driving to campus of nine percentage points. Car availability during term-time fell by 14 percentage points and licence-holding fell by nine percentage points. The policy change was associated with greater changes amongst females than males. Overall, the results suggest that removing the right of young adults to park at a frequent destination delayed their acquisition of driving licences and cars. These findings may explain part of the fall in licence-holding observed amongst young adults in Great Britain in recent decades

A feasibility study in rearchitecting UML as a family of languages using a precise OO meta-modeling approach.

This report describes a feasibility study in rearchitecting UML. It develops a theory of precise OO meta-modeling in order to fulfil this task, and checks the feasibility of that theory by developing the meta-model of various aspects of UML
