    Despite women’s recent gains in education and employment, husbands still tend to out-earn their wives. This article examines the relationship between the partner pay gap, i.e. the difference in earned income between married, co-resident partners, and life satisfaction. Contrary to previous studies, we investigate the effects of recent changes in relative earnings within couples as well as labour market transitions. Using several waves of the UK Household Longitudinal Study, we reveal that men exhibit an increase in life satisfaction in response to a recent increase in their proportional earnings. For women their proportional earnings had no effect on life satisfaction in one model, and in a model that accounted for their recent employment changes, women exhibited decreased life satisfaction. We also find secondary-earning husbands report lower average life satisfaction than primary-earning men, while such differences were not found for women. The analysis offers compelling evidence of the role of gendered norms in the sustenance of the partner pay gap

    Analyzing Fragmentation of Simple Fluids with Percolation Theory

    We show that the size distributions of fragments created by high energy nuclear collisions are remarkably well reproduced within the framework of a parameter free percolation model. We discuss two possible scenarios to explain this agreement and suggest that percolation could be an universal mechanism to explain the fragmentation of simple fluids.Comment: 12 pages, 11 figure

    Partial energies fluctuations and negative heat capacities

    We proceed to a critical examination of the method used in nuclear fragmentation to exhibit signals of negative heat capacity. We show that this method leads to unsatisfactory results when applied to a simple and well controlled model. Discrepancies are due to incomplete evaluation of potential energies.Comment: Modified figures 3 and

    Logic and theory of representation

    Full text link
    Underlying the theory of inferences, a primary task of logic is language analysis. Such a task can be understood as depending on a general theory of representation, taking as a starting point the idea that some entities (`` representations '') can present some entites (`` contents ''). We outline a theory of representation accounting for the capacity of representational systems to access universes that extend beyond an immediate presence. We define three logical properties that any adequate representational system should have: completeness, faithfulness, coherence. We show that logical laws are laws of representation. Finally, it appears that logic can be considered as the abstract theory of representation

    Beyond Mutexes, Semaphores, and Critical Sections

    International audienceThe traditional approach to multitasking synchronization has been to use Mutexes, Semaphores, and Critical sections. However, those primitives can lead to inefficiency or, even worse, to error conditions such as, for example, dead or live locks or priority inversion. The problems with those primitive are particularly vivid with real-time systems. Also, with the rapid deployment of multi-core systems, those traditional mechanisms are showing new classes of issues. This talk will discuss how the use of non-blocking algorithms through atomic and barrier operations can lead to more robust, deterministic and higher performance systems
