Employers' policies for third age employment – the case for action and the rational for reaction
This paper reports on findings from a study which explores employers’ perceptions of the careers of those in third age employment and the extent to which these organisations have in place policies and practices to manage older worker careers. Drawing on interviews with UK HR managers and advisory bodies, the study finds that there was an absence of formal policies which addressed the career needs of older works despite employers being aware of the issue associated with an aging workforce. Instead employers responded to career related requests from older workers on an ad hoc basis as they felt that specific policies for this group of people would potentially create legal issues for the organisation. Employers also believed that the aged workforce had little impact on their business and as a result did not engage in collective dialogue with older workers about their requirements and instead made assumptions about their career needs

Response to ‘Protected areas and climate change Reflections from a practitioner's perspective
Cliquet et al. 1 provide a thought-provoking analysis of the challenges posed to
the EU's protected areas by climate change. This paper seeks to build on some of
the perspectives they brought to what is a highly challenging area of nature
conservation law, policy and practice. While there is much to support in their
analysis of the relationships between protected areas and climate change, there
are two key strands we seek to develop further, based on the RSPB's experience
of this area of nature conservation policy and practice: first, is the
ecological model for adapting to climate change and second, the legal framework
provided by the Birds2 and Habitats3 Directives (the Nature Directives) as it
relates to the delivery of such adaptive actions
Development of CO2 laser Doppler instrumentation for detection of clear air turbulence, volume 2: Appendices
Analyses of the mounting and mount support systems of the clear air turbulence transmitters verify that satisfactory shock and vibration isolation are attained. The mount support structure conforms to flight crash safety requirements with high margins of safety. Restraint cables reinforce the mounts in the critical loaded forward direction limiting maximum forward system deflection to 1 1/4 inches
Traveling waves and homogeneous fragmentation
We formulate the notion of the classical
Fisher-Kolmogorov-Petrovskii-Piscounov (FKPP) reaction diffusion equation
associated with a homogeneous conservative fragmentation process and study its
traveling waves. Specifically, we establish existence, uniqueness and
asymptotics. In the spirit of classical works such as McKean [Comm. Pure Appl.
Math. 28 (1975) 323-331] and [Comm. Pure Appl. Math. 29 (1976) 553-554], Neveu
[In Seminar on Stochastic Processes (1988) 223-242 Birkh\"{a}user] and Chauvin
[Ann. Probab. 19 (1991) 1195-1205], our analysis exposes the relation between
traveling waves and certain additive and multiplicative martingales via laws of
large numbers which have been previously studied in the context of
Crump-Mode-Jagers (CMJ) processes by Nerman [Z. Wahrsch. Verw. Gebiete 57
(1981) 365-395] and in the context of fragmentation processes by Bertoin and
Martinez [Adv. in Appl. Probab. 37 (2005) 553-570] and Harris, Knobloch and
Kyprianou [Ann. Inst. H. Poincar\'{e} Probab. Statist. 46 (2010) 119-134]. The
conclusions and methodology presented here appeal to a number of concepts
coming from the theory of branching random walks and branching Brownian motion
(cf. Harris [Proc. Roy. Soc. Edinburgh Sect. A 129 (1999) 503-517] and Biggins
and Kyprianou [Electr. J. Probab. 10 (2005) 609-631]) showing their
mathematical robustness even within the context of fragmentation theory.Comment: Published in at http://dx.doi.org/10.1214/10-AAP733 the Annals of

Dynamics, Rectification, and Fractionalization for Colloids on Flashing Substrates
We show that a rich variety of dynamic phases can be realized for mono- and
bidisperse mixtures of interacting colloids under the influence of a symmetric
flashing periodic substrate. With the addition of dc or ac drives, phase
locking, jamming, and new types of ratchet effects occur. In some regimes we
find that the addition of a non-ratcheting species increases the velocity of
the ratcheting particles. We show that these effects occur due to the
collective interactions of the colloids.Comment: 4 pages, 4 postscript figures. Version to appear in Phys. Rev. Let
