No full textTransports publics et décentralisation
No full textL'ouvrage publié constitue un livre référence des 40 années de décentralisation faisant suite aux lois Defferre de 1982.
Dans le domaine des transports publics, les progrès réalisés sont incontestables. Pourtant, l’État conserve une part de ses prérogatives malgré les multiples textes publiés depuis 40 ans.
Les lois LOTI, MAPTAM, NOTRE, LOM et, bientôt, la loi L3DS caractérisent ces évolutions. Les progrès sont incontestables mais l'Etat ne se résout pas à déléguer certaines de ses prérogatives
Die Tradition der Machtbegrenzung. Über die Rolle des Bundesverfassungsgerichts, Verrechtlichung der Politik und Unterschiede zu Frankreich spricht Reinhard Müller mit Aurore Gaillet
No full textDecentralised Cross-Border Interconnection
No full textReaping the full benefits from cross-border interconnection typically requires reinforcement of national networks. When the relevant parts of the networks are complements, a lack of coordination between national transmission system operators typically results in investment below optimal levels in both interconnectors and national infrastructure. A subsidy to financially sustain interconnector building is not sufficient to restore optimality; indeed, even
when possible, such subsidisation may have to be restrained so as not to encourage cross-border capacities that will not be fully utilised due to lack of
investment in national systems
Inference for extremal regression with dependent heavy-tailed data
No full textNonparametric inference on tail conditional quantiles and their least squares analogs, expectiles, remains limited to i.i.d. data. Expectiles are themselves quan- tiles of a transformation of the underlying distribution. We develop a fully operational kernel-based inferential theory for extreme conditional quantiles and expectiles in the challenging framework of ↵-mixing, conditional heavy-tailed data whose tail index may vary with covariate values. This extreme value problem requires a dedicated treatment to deal with data sparsity in the far tail of the response, in addition to handling diffi culties inher- ent to mixing, smoothing, and sparsity associated to covariate localization. We prove the pointwise asymptotic normality of our estimators and obtain optimal rates of convergence reminiscent of those found in the i.i.d. regression setting, but which had not been estab- lished in the conditional extreme value literature so far. Our mathematical assumptions are satisfied in location-scale models with possible temporal misspecification, nonlinear regression models, and autoregressive models, among others. We propose full bias and variance reduction procedures, and simple but e↵ective data-based rules for selecting tun- ing hyperparameters. Our inference strategy is shown to perform well in finite samples and is showcased in applications to stock returns and tornado loss data
Perceived organizational support and task performance of employees with disabilities: a need satisfaction and social identity perspectives
No full textIn this article, we combine insights from basic psychological needs theory and the social identity approach to propose that perceptions of organizational support enhance the basic need satisfaction of employees with disabilities, which yields higher levels of task performance. We also suggest that disability group identification strengthens this mediational process. We tested our hypotheses with two quantitative field studies that were conducted in France and based on matched employee-supervisor data. Using a sample of employees working in companies that specialize in the employment of persons with disabilities, Study 1 aimed to provide initial evidence for the mediating role of basic need satisfaction. Study 2 aimed to replicate the findings of Study 1 in less specific contexts while testing the moderating role of disability group identification. Next, the methodological limitations of these investigations were addressed in two quantitative post hoc studies. The results of these studies support our model and generate new knowledge about whether, why and when the perception of favorable treatment contributes to the job performance of employees with disabilities. We also discuss the practical implications of our findings and provide suggestions for human resources managers
Human cumulative culture and the exploitation of natural phenomena
No full textCumulative cultural evolution (CCE)—defined as the process by which beneficial modifications are culturally transmitted and progressively accumulated over time—has long been argued to underlie the unparalleled diversity and complexity of human culture. In this paper, I argue that not just any kind of cultural accumulation will give rise to human-like culture. Rather, I suggest that human CCE depends on the gradual exploitation of natural phenomena, which are features of our environment that, through the laws of physics, chemistry or biology, generate reliable effects which can be exploited for a purpose. I argue that CCE comprises two distinct processes: optimizing cultural traits that exploit a given set of natural phenomena (Type I CCE) and expanding the set of natural phenomena we exploit (Type II CCE). I argue that the most critical features of human CCE, including its open-ended dynamic, stems from Type II CCE. Throughout the paper, I contrast the two processes and discuss their respective socio-cognitive requirements
