Job Satisfaction And Family Happiness: The Part-Time Work Problem
Using fixed effects ordered logit estimation, we investigate the relationship between part-time work and working hours satisfaction; job satisfaction; and life satisfaction. We account for interdependence within the family using data on partnered men and women from the British Household Panel Survey. We find that men have the highest hours-of-work satisfaction if they work full-time without overtime hours but neither their job satisfaction nor their life satisfaction are affected by how many hours they work. Life satisfaction is influenced only by whether or not they have a job. For women we are confronted with a puzzle. Hours satisfaction and job satisfaction indicate that women prefer part-time jobs irrespective of whether these are small or large. In contrast, female life satisfaction is virtually unaffected by hours of work. Women without children do not care about their hours of work at all, while women with children are significantly happier if they have a job regardless of how many hours it entails.part-time work;happiness;satisfaction;working hours;gender
Hours of Work and Gender Identity: Does Part-time Work make the Family Happier?
Taking into account inter-dependence within the family, we investigate the relationship between part-time work and happiness.We use panel data from the new Household, Income and Labor Dynamics in Australia Survey.Our analysis indicates that part-time women are more satisfied with working hours than full-time women. Partnered women's life satisfaction is increased if their partners work full-time.Male partners' life satisfaction is unaffected by their partners' market hours but is increased if they themselves are working full-time.This finding is consistent with the gender identity hypothesis of Akerlof and Kranton (2000).parttime workers;gender differences;happiness;gender identity
Arc-parallel vs back-arc extension in the Western Gibraltar arc : is the Gibraltar forearc still active?
Extremely tight arcs, framed within the Eurasia-Africa convergence region, developed during the Neogene on both sides of the western Mediterranean. A complex interplate deformation zone has been invoked to explain their structural trend-line patterns, the shortening directions and the development of back-arc basins. Updated structural and kinematic maps, combined with earthquake data covering the complete hinge zone of the western Gibraltar arc help us to explore the mode of strain partitioning from 25My ago to present. During the Miocene, the strain partitioning pattern showed arc-perpendicular shortening in the active orogenic wedge -assessed from the radial pattern of tectonic transport directions- accompained by subhorizontal stretching. Structures accommodating stretching fall into two categories on the basis of their space distribution and their relationships with the structural trend-line pattern: i) arc-parallel stretching structures in the external wedge (mainly normal faults and conjugate strike-slip faults); and ii) extensional faults developed in the hinterland zone in which transport directions are centripetal towards the AlborĂĄn back-arc basin.

Spin-polaron model: transport properties of EuB
To understand anomalous transport properties of EuB, we have studied the
spin-polaron Hamiltonian incorporating the electron-phonon interaction.
Assuming a strong exchange interaction between the carriers and the localized
spins, the electrical conductivity is calculated. The temperature and magnetic
field dependence of the resistivity of EuB are well explained. At low
temperature, magnons dominate the conduction process, whereas the lattice
contribution becomes significant at very high temperature due to the scattering
with the phonons. Large negative magnetoresistance near the ferromagnetic
transition is also reproduced as observed in EuB.Comment: 4 pages, 3 figures, accepted in Phys. Rev.
The Three Dimensional Thirring Model for Small N_f
We formulate the three dimensional Thirring model on a spacetime lattice and
study it for various even numbers of fermion flavors N_f by Monte Carlo
simulation. We find clear evidence for spontaneous chiral symmetry breaking at
strong coupling, contradicting the predictions of the 1/N_f expansion. The
critical point appears to correspond to an ultra-violet fixed point of the
renormalisation group; a fit to a RG-inspired equation of state in the vicinity
of the fixed point yields distinct critical exponents for N_f=2 and N_f=4,
while no fit is found for N_f=6, suggesting there is a critical number N_fc<6
beyond which no chiral symmetry breaking occurs. The spectrum of the N_f=2
theory is studied; the states examined vary sharply but continuously across the
transition.Comment: 50 pages LaTeX, including 16 tables and 20 figures - uses style file

Critical scaling of the a.c. conductivity for a superconductor above Tc
We consider the effects of critical superconducting fluctuations on the
scaling of the linear a.c. conductivity, \sigma(\omega), of a bulk
superconductor slightly above Tc in zero applied magnetic field. The dynamic
renormalization- group method is applied to the relaxational time-dependent
Ginzburg-Landau model of superconductivity, with \sigma(\omega) calculated via
the Kubo formula to O(\epsilon^{2}) in the \epsilon = 4 - d expansion. The
critical dynamics are governed by the relaxational XY-model
renormalization-group fixed point. The scaling hypothesis \sigma(\omega) \sim
\xi^{2-d+z} S(\omega \xi^{z}) proposed by Fisher, Fisher and Huse is explicitly
verified, with the dynamic exponent z \approx 2.015, the value expected for the
d=3 relaxational XY-model. The universal scaling function S(y) is computed and
shown to deviate only slightly from its Gaussian form, calculated earlier. The
present theory is compared with experimental measurements of the a.c.
conductivity of YBCO near Tc, and the implications of this theory for such
experiments is discussed.Comment: 16 pages, submitted to Phys. Rev.
