Abstract
The National Museum of Natural History has been carrying out, over the last several years, a study of hominid fossil skulls, which have been discovered in different regions of the world. The aim of the palaeo‐anthropological study of these skulls is to reconstruct the genealogic tree of the evolution of man and to understand better, the diversity of the homo Erectus species on the different continents. Currently, digital techniques and those of rapid prototyping offer a solution to these problems by allowing the virtual or physical reconstitution of the skulls for scientific study. This paper presents this new perspective for the world of palaeontology.

Abstract
The work deals with the topic of spare parts management in a space system. The paper is divided into three parts. The first one is dedicated to the characterization of the system structure and presents the particularities related to the spare‐elements procurement. Modelling is the object of the second part. After having exposed the bases of the problem to be solved, a macro‐model is introduced. Each of the three elements of an orbital system, namely ground, flying and transport, is then described with a Petri net. Operation specificities of every element are then listed and integrated into the model. A concrete application of this modelling is given in the last part. It concerns the Columbus laboratory of the International Space Station. A representative function is selected and several supply strategies are evaluated.

Abstract
This article presents a method of management of the initial spare parts supply. This generic problem is of particular interest in certain systems in which the difficulty of accessibility or the life cycle duration constitute risks tied to the possible depletion of the spare parts stock. In this paper we consider the spatial context. After having commented on the particularities of the management of the spare parts supply of a space station, we propose a method based on the minimization of the risk of postponement of a maintenance operation. Finally, an application to the Columbus laboratory of the International Space Station is presented.

Abstract
In a seeming attempt to legitimate or otherwise dignify social economics (Économie sociale, etc.), “named” economists (Adam Smith, Karl Marx et al.) have been dubbed social economists and/or regarded as having made significant but unrecognised contributions thereto. Conspicuously absent from that roster of celebrities are Léon Walras, économiste social par excellence, et al., who have distinguished themselves in the mainstream but also have done social economy(ics) explicitly, i.e. by that designation. Included in that illustrious et al. list are François Quesnay, J.B. Say, Friedrich von Wieser and Knut Wicksell (inter alios). Their due recognition, as per the present essay, cannot help but measurably further legitimise/dignify social economics.

Abstract
The distinction between “observed” and “observing” systems that legitimizes the rise of second‐order cybernetics also raises a number of methodological and epistemological issues. These can be generically classified into two broad groups: first, adherence to the model approach and its overemphasis on cognition, at the expense of conation and other factors responsible for the initiation of action; second, an inadequate appraisal of the nature of language and its role within the sum total of human behavior. The overall result is the perennial confusion between the behavior of the expert and that of the subjects under investigation. Underlying both of these, in the final reckoning, is the hypostatical nature of the linguistic and logical constructs employed. The ambiguity surrounding “observing systems” begins to dissipate when we realize that second‐order cybernetics is not so much about an “observer” as about a “self‐observer”. The study of self‐referentiality is not only about language; it is about other forms of behavior as well.

Abstract
Purpose
The purpose of this paper is to show that football as a sacred experience is often raised, but has never led to an argued approach. Professional football (soccer) is a genuine societal phenomenon, both through the medias’ interest they cause and through the financial stakes that are related to it. It is common to read that football, through the passions it unleashes, for example in terms of tribal violence, has become a type of religion, with its believers (the fans) and its place of worship (the stadiums).
Design/methodology/approach
The authors reviewed the literature, research reports and electronic documents on professional football practices to understand the religious dimension of fan passion in Europe (ritualism, collective beliefs, using of totemic objects, etc.).
Findings
The paper suggests a reading grid of religions, founded on four interdependent dimensions (the Community, the Law, the Way and the Experience) and applies it to professional football by underlying its relevance in the singular context of sports show.
Originality/value
Beyond well-known economic stakes, the paper clarifies the football passion from a religious perspective and identifies the main pillars of the fan conversion process according to a heteronomous logic.

Abstract
Map of this detour: This is one of a series of detours compelled by consideration of inheritance law as an aspect of cultural transmission. 1 This course draws attention to three problematic time forms (temporalities) through which the “self” and its relations with history are often written and read. These implicit time forms are all too common and all too easily go unrecognized. Each involves the illusion of some kind of exalted and immediate convergence between the self (the subject) and an object of exaggerated importance to this self (the world, the universe, the metaphysical or artistic beyond, the origin, etc.). Three figures are explored here: that of Hercules in Hegel’s Aesthetics, and those of Adrian and Breisacher in Thomas Mann’s Doctor Faustus. Each of these invites attention to a different temporality through which an exalted convergence may be imagined: the first involves a fantasy of immediate belonging to the whole of history, the second, that of escape forward from history (toward a self-created “ultimate” object), and the third, that of return to fullness in origin (before history). This detour also suggests ways of reading history (including “reading for mana through glances,” which will be explained) that protect against the problems just described. The detour closes considering implications of all of the above for U.S. inheritance law. The tutor text for this last leg is François Mauriac’s Le noeud de vipères.

Abstract
Purpose
Spatial autocorrelation in regression residuals is a major issue for the modeller because it disturbs parameter estimates and invalidates the reliability of conclusions drawn from models. The purpose of this paper is to develop an approach which generates new spatial predictors that can be mapped and qualitatively analysed while controlling for spatial autocorrelation among residuals.
Design/methodology/approach
This paper explores an alternate approach using a Fourier polynomial function based on geographical coordinates to construct an additional spatial predictor that allows to capture the latent spatial pattern hidden among residuals. An empirical validation based on hedonic modelling of sale prices variation using a large dataset of house transactions is provided.
Findings
Results show that the spatial autocorrelation problem is under control as shown by low Moran's I indexes. Moreover, this geo‐statistical approach provides coefficients on environmental amenities that are still highly significant by capturing only the remaining spatial autocorrelation.
Originality/value
The originality of this paper relies on the development of a new model that allows considering, simultaneously spatial and time dimension while measuring the marginal impact of environmental amenities on house prices avoiding competition with the weight matrix needed in most spatial econometric models.

Abstract
This chapter attempts to offer a clearer look at the historical roots of the founding of mutualist finance. Without denying that the various forms of financial mutualism may have legal and organizational roots in ancient times, the author considers what, for contemporary mutualist banks, may constitute the soul.
In its first part, the document presents the individual constructions that existed in the eighteenth and nineteenth centuries, in a context in which economic development and the industrial revolution banished the rules and standards of the former society. It refers to Utopian socialisms as opposed to the scientific solutions proposed for a new social organization and to the new solidarism according to Léon Bourgeois. Christian sources are also called to mind with social Christianity (Protestant) and social Catholicism until the birth of the social doctrine of the Church.
This frenzy of ideas as well as the confrontation with reality led to the birth, in Germany, of the first experiments with alternative finance. This is the subject of the second part of this chapter, which then develops the bank mutualism created by the founding fathers, F.W. Raiffeisen and H. Schulze-Delitzsch.
The historical description of the creation of mutualist banks brings up two major problems when talking about the “other finance”: the interest and activity of the bank. Is an ethical finance capable of proposing a credible alternative? This is a question that needs to be answered in the light of history.
This chapter attempts, more than 150 years after the fact, to demonstrate the ponderous presence of the question and the permanence of the founding ideas in order to comprehend the facts and propose ideas for analysis and construction of an “other finance.”
