Qu'il soit écrit ou verbal, qu'il constitue une réponse aux questions du chercheur ou qu'il résulte d'une quelconque interaction sociale, le discours occupe une place privilégiée parmi les matériaux empiriques du chercheur en sciences sociales. Ce donné, chargé de toute la complexité du langage, ne peut être valablement appréhendé par une lecture immédiate. Diverses méthodes se sont constituées avec une double visée : la mise au point de procédés d'analyse et leur adaptation à une perspective sociologique. Pour les désigner brièvement, on utilise le terme d'analyse de contenu. Mais au-delà de cette appellation commune, la diversité des méthodes laisse perplexes les utilisateurs. Dans cet ouvrage, quatre praticiens exposent et appliquent leur méthode : l'herméneutique collective, l'analyse textuelle de J. Gritti, une méthode d'analyse de l'ethos proposée par Chr. Lalive d'Epinay et l'analyse structurale. Le lecteur pourra ainsi cerner l'apport respectif de chacune de ces méthodes et sera invité à une lecture comparative et critique. Cette réflexion sera amorcée dans deux directions : celle d'une confrontation avec la tradition des sciences du langage et celle de la pertinence du lien qui s'établit entre la méthode et l'intention sociologique. L'ouvrage s'adresse à l'étudiant, au chercheur, à l'enseignant et à tout lecteur intéressé par les sciences sociales ou les analyses qualitatives.

Cet ouvrage constitue une introduction a une sociologie compréhensive du changement social, qui place l'acteur social au cœur de son questionnement. À partir d'une élucidation prospective de l'œuvre de Maurice Chaumont l'ouvrage propose un ensemble de textes qui portent sur les principales facettes du travail sociologique, tel que le concevait Maurice Chaumont : la réflexion épistémologique, l'essai, la problématisation et la construction de modèles d'analyse ainsi que l'analyse concrète. À travers l'unité du projet et la complémentarité des différents apports, une manière neuve d'aborder le changement social est proposée ici, dont l'intérêt est à la fois théorique, pratique et pédagogique. Des chercheurs de l'École des hautes études en sciences sociales à Paris (Alain Touraine), de l'Université de Sao Paulo (José-A Guilhon Albuquerque), de l'Université de Montréal (Annick Germain), des Universités du Zaïre (Benoit Verhaegen) et du Centre d'étude et de documentation africaines (Gauthier de Villers et Benoit Verhaegen), de l'Université catholique de Louvain (Guy Bajoit. Jean Ladrière, Michel Molitor et Jean Remy) et du Centre d'études sociologiques des facultés universitaires Saint-Louis (Anne Devillé, Michel Hubert, Jean Remy et Luc Van Campenhoudt participent à cet ouvrage d'hommage.

DE NOUVEAUX LIEUX D’URBANITÉ se développent-ils dans le cadre d’espaces dont l’urbanisation est récente ? Ces lieux d’urbanité reposent-ils sur la mise en place d’espaces piétons attirant des populations qui y viennent pour des motifs divers ? Leur réussite dépend-elle entre autres d’un cadre bâti conçu à l’échelle du piéton et qui accompagne les flux en contribuant à créer une certaine ambiance ? Indirectement, cela revient à s’interroger sur la rue et la place comme formes architecturales d...

Figure multiple, figure mythique aussi, la rue est au fondement de l'espace public urbain qu'elle traverse et qu'elle irrigue de la circulation des hommes et des marchandises. Elle est un lieu de sociabilité ouverte que s'approprient différemment les individus et les groupes selon des règles de coexistence modulées par un jeu de distance et de proximité. Elle est le lieu où l'on fait l'expérience de la diversité. Cet ouvrage présente une pluralité de points de vue et de thèmes sur la rue et par extension sur la ville : le public et le privé, la violence, le commerce, le mouvement, le brassage, la cohabitation... Chacun de ces points de focalisation est un des morceaux du puzzle urbain. De la typologie descriptive à laquelle se prête la diversité des terrains, on passe à une topologie interprétative riche de perspectives nouvelles.

La complexité croissante de la vie en société rend le changement social plus difficile. La transaction sociale constitue un bon outil pour comprendre et changer le monde. En 1978 et 1980, Jean Remy, Liliane Voyé et Émile Servais publiaient l’ouvrage fondateur de la transaction sociales, depuis longtemps épuisé, Produire ou reproduire ? en écho au débat qui opposait Pierre Bourdieu, défenseur de la reproduction de la société, à Alain Touraine, pour lequel il y avait production d’une société nouvelle par les mouvements sociaux. Entre ces deux visions incompatibles, les trois auteurs imaginaient des rapprochements ponctuels et partiels, ou transactions sociales. Contrairement à la transaction économique, la transaction sociale fait passer les valeurs avant les intérêts. Elle ne fait pas disparaître les conflits mais les « apprivoise » : la transaction sociale génère des compromis acceptables qui permettent de coopérer malgré des désaccords persistants. En rendant les textes majeurs accessibles à un large public, cet ouvrage en montre la fécondité comme outils d’analyse de la réalité sociale. Sa conceptualisation s’est enrichie et complexifiée en quarante ans grâce notamment aux travaux du comité de recherche « Transactions sociales, cultures, émancipations » de l’Association internationale des sociologues de langue française (AISLF).

DIAGNOSIS. ��� Rather large Pachynolophus species, LRDJ = 51- 53 mm; estimated weight about 21 kg. Buno-lophodont dentition. Ectoloph of upper molars fairly flat, devoid of mesostyle and usually without pseudomesostyle. Deeply hollowed centrocrista. Relative surface of the premolar area not greatly reduced for a Pachynolophus, estimated at 44% of that of molars. Transversally elongated upper premolars, but with a lingual contour not specially narrowed. Rather straight lophids on lower molars; the transverse ones dug at midway. Labial crest of the M/3 hypoconulid connected to the mid hypolophid. Relatively thick and high cingula, almost wholly surrounding upper premolars, only missing on lingual side of lower molars. DPC of variable length but generally less elongated than in most other Pachynolophus. DIFFERENTIAL DIAGNOSIS. ��� Larger than most Pachynolophus species, except Pa. cayluxi. More lophodont dentition than that of Pa. eulaliensis and Pa. cesserasicus, but much less than that of Pa. lavocati and Pa. zambranensis. Centrocrista of upper molars more dug than those of Pa. bretovensis and Pa. garimondi. Greater relative surface of the premolar area than that of Pa. molipontiensis, Pa. livinierensis, Pa. cesserasicus and Pa. lavocati. Less transversally elongated P4/ than in Pa. cayluxi, Pa. gaytei and Pa. cesserasicus with a less narrow lingual outline. Presence of a distinct metaconule on P4/, contrary to Pa. boixedatensis and M3/ not so large. Postero-lingual basin of P4/ less broad than that of Pa. bretovensis and Pa. garimondi. Thicker and higher cingula than in these latter species, wider also than in Pa. duvali. DESCRIPTION Upper cheek teeth The type-specimen AUM 231 is in very good condition; only the M1/ bears notable signs of wear. It is a medium-sized Pachynolophinae (LRDJ = 51.3 mm), slightly smaller than Propalaeotherium sudrei but larger than most hyracotheres. Dimensions of the whole material reported to the taxon suggest a body weight of about 21 kg following the equations in Janis (1990) (Appendix 8), with coefficients of size variability (V) mostly Pachynolophus (Remy 1972). On AUM 231, the ratio SP/SM is estimated at 44 (Appendix 21) and the PMI at 65.7. P4/ is transversely elongated; the labial bulge of paracone and metacone is very marked and the centrocrista of ectoloph less notched than on molars. P3/ has an identical shape, but it is slightly less transversally elongated, with closer outer cusps and less notched centrocrista. As molars, the premolars exhibit some morphological variability. Indeed, some premolars differ markedly from homologous teeth of the holotype. Thus, some P3/ and P4/ have a pronounced concavity of the labial outline (AUM 1553, AUM 1628). There is a strong labial cingulum on the P3/-P4/ of AUM 231, continuous and extended by a poorly developed parastyle. The latter can still be weaker (AUM 1544, AUM 1554 [P4/], AUM 1552, AUM 1566 [P3/]). The protocone of P3/-P4/ is generally axially located. It is slightly shifted forward on AUM 231, and even more forward on some P3/ (AUM 1552). The paraconule of these teeth is bulbous on AUM 231, rather separated from the protocone and clearly lower. It is weaker with the groove between paraconule and protocone being shallower on other specimens (AUM 1554 AUM 1567, AUM 1628). The rounded metaconule is labially extended by a thin rectilinear postprotocrista ridge oriented toward the centrocrista on AUM 231. The transverse lophs are more V-shaped with less distinct conules on AUM 1552 and AUM 1553. On the holotype, a thick and continuous cingulum surrounds the whole inner part of P3/-P4/ up to the ectoloph, but without any enlargement of a posterior basin unlike in some P3/ (AUM 1552, AUM 1553). The lingual cingulum is weaker and interrupted at protocone level on some P4/ (AUM 1554, AUM 1567) or P3/ (AUM 1552, AUM 1553). The P 3/ (AUM 70), which displays a particularly weak and low metaconule, has a forward shifted protocone and lacks lingual cingulum. A P2/ is preserved on the holotype. It is a small ovoid tooth, narrow mesially and wide distally. It has two very close labial cusps with the metacone hard to individualize and lower than the paracone. The other known P2/ (AUM 1552) is a bit smaller and more rounded in shape. Its high labial cusp is extended distally by a crest devoid of any hint of an incipient metacone. The ectocingulum is faint and the styles poorly defined on AUM 231. The oblique lingual cingulum is enhanced by a small elongated protocone. In the distal basin, a tiny and very low crest evokes a faint preprotocrista. On AUM 1552, the protocone is more individualized and there is no crest in the worn basin. The P1/ are preserved on AUM 1544. They are simple narrow teeth with a prominent cusp barely shifted rostrally and a surrounding cingulum. It seems that there was place for a short diastema between P1/ and P2/. The presence of a P1/ is also attested on AUM 231 by two alveoli indicating a tooth as long but narrower than P2/. There was no P1/-P2/ diastema on this specimen. The alveolus of upper canine indicates a large and rather narrow tooth. The deciduous dentition is known by an upper jaw (AUM 1618), whose teeth are unfortunately fractured and crumbled, and by a DP3/ (AUM 186). The DP4/ is molarized, has a high and rather protruding parastyle and lacks a mesostyle. The groove between paracone and protocone appears rather deep. The hypocone is less lingual in position than the protocone. The lingual cingulum is narrow and interrupted on hypocone. The DP3/ are also molariform but with a slightly oblique mesio-lingual outline. On AUM 186, the protocone is shifted labially relative to hypocone and slightly lower, with a deep lingual notch between protocone and hypocone. The paracone-protocone groove is shallower than on AUM 1618. The metaloph is curved on AUM 186 due to the presence of a small accessory distal cusp. The cingulum is thick and high, surrounding the tooth and only slightly broken at the paracone. DP2/ is an elongated narrow triangular tooth. The paracone is prominent with a close low metacone. The parastyle is welldeveloped like an anterior cusp. The inner part of the tooth is chipped. DP1/, which is not preserved, had two roots. Lower cheek teeth (Fig. 9) The lower molars are characterized by rather pointed crescents. The lophids are rather straight and lophodont. The transverse ones appear to be dug midway when unworn. The trigonid is rather short, even shorter than talonid. The preprotocristid is lowered, and curved mesially, without any trace of paraconid. The metaconid is clearly splitted. The metalophid is connected between metaconid and metastylid. The hypoconulid is well developed on the middle of distal edge of M/1 and M/2. The labial crest of hypoconulid of M/3 reaches the middle of hypolophid and the curved lingual crest bears small knobs (AUM 161, AUM 169). The ectocingulum of molars is usually well marked, relatively high (about 2 mm for a total unworn cusp height of 6 mm on AUM 161) and fairly continuous (AUM 161, AUM 217), but can be weaker and more or less interrupted on cuspids (AUM 169, AUM 185, AUM 1568, AUM 1605). Not any lower molar bears a lingual cingulum. The lower premolars are known only by isolated teeth. Those that we interpret as P/4 (see material) are rectangular and generally not narrowed mesially. The trigonid is molariform with a split metaconid (AUM 1640). The mesial crest of the protoconid is lowered; on AUM 1640 it terminates by a small, split paraconid. The talonid is slightly lower than the trigonid. The hypoconid is shifted labially. Although there is no entoconid, the hypoconid is sometimes extended by a low lingual cristid, a weak clue of an incipient cuspid (AUM 1642). The ectocingulum is generally weak, sometimes restricted to the medivallum (AUM 1629, AUM 1643). P/3 has an identical morphology, but the tooth tapers anteriorly, thus the trigonid is narrower than the talonid and somewhat more flattened (AUM 178). Like on P/4, the hypoconid is shifted labially, without any entoconid. The ectocingulum is rather weak. Three P/2 could be assigned to the species. They are simple teeth with one prominent cuspid (protoconid) slightly shifted rostrally. A parasagittal mesial ridge and a slightly linguo-distal one represent the relicts of the trigonid crescent. On AUM 1612, both ridges end with a very small knob. There is no true talonid, only another low parasagittal crest behind protoconid, terminated by a very small tubercle equivalent to a vestigial hypoconid. The ectocingulum is noticeable, but stopped on protoconid. P/1 (AUM 167), is an even more simple, bi-rooted tooth. The canines, also present on that specimen, are small suggesting it belongs to a female. The most complete canine (on the right) is eroded by a large distal surface of wear. DP/4 is molariform but can be slightly narrow mesially (AUM 1605). It differs from the molars by the lower crown height and the thinness of the enamel (AUM 1630). The paralophid is devoid of a paraconid and the metaconid is clearly split. The talonid is as high as the trigonid and the entoconid as large as the hypoconid. The presence of an hypoconulid is noticeable. The ectocingulum is weak and interrupted on cuspids. DP/3 is narrow mesially but the crescent of the trigonid is fully developed (AUM 1556). An accessory small cuspid is observed on the lingual side of the mesial cristid of the protoconid. The talonid is wide and the entoconid is as high as the hypoconid like on DP/4. Other anatomical data The length of the post-canine diastema (DPC) appears variable in the sample. On a maxilla (AUM 231), it is relatively short (17 mm, i.e. 33% of the length of the cheek teeth row LRDJ [LP2/-M3/], Appendix 20A), but on AUM 1544, it could have exceeded 50% of LRDJ. On mandibles, the length of the DPC can only be known indirectly on AUM 161, which preserves the molar row but is crushed in the premolar region. With a molar length of 33.6 mm and assuming a PMI between 0.67 and 0.70 (an average value for a Pachynolophus), the LRDJ length can be estimated at 56-57 mm. Furthermore, the socket of the canine is missing and the part of the DPC preserved until the anterior alveolus of P/2 is 23 mm long. The DPC would not therefore have been lower than 40 or 41% of LRDJ. With a length of 33 mm, the DPC of AUM 167 would have had a greater relative value, probably over 50% (Appendix 20B).

The FIO is rather rostrally situated, at 7 mm above P3/ (AUM 231, AUM 1552). On the juvenile AUM 1618, it appears above DP2/. The anterior edge of the orbit (O) levels the mesial border of M2/. The orbital floor is very low (HTMX about 5 mm), and moreover hilly by the relief of the roots of the last molars. The palate is slightly crushed (AUM 231) but appears hollow. It seems neverthe- less have been rather narrow after correction of that crash (taking into account the position of the spine of the median raphe). The maxillary zygomatic process, which is not very dorso-ventrally high (7 mm at orbit level) is expanded laterally, but the bow does not seem to have strongly diverged at the back, like on Pachynolophus livinierensis. On AUM 161, the mandibular body is not very high and only increases slightly backwards (13.3 mm under DPC; 16.8 mm under P/2; 23.4 mm under M/3). The values are close for AUM 169. On the juveniles AUM 1556 and AUM 1605, the mandibular height increases from 16 mm under DP/ 3 to 18 mm under M/2.

Genus Pachynolophus Pomel, 1847 TYPE SPECIES. ��� Pachynolophus duvali Pomel, 1847 by original designation. INCLUDED SPECIES. ��� Pa. cesserasicus Gervais, 1849; Pa. cayluxi (Filhol, 1888); Pa. livinierensis Savage, Russell & Louis, 1965; Pa. garimondi Remy, 1967; Pa. boixedatensis Crusafont & Remy, 1970; Pa. lavocati Remy, 1972; Pa. bretovensis Remy, 1988; Pa. molipontiensis Checa-Soler, 1994; Pa. zambranensis Badiola, Pereda-Suberbiola & Cuesta, 2005; Pa. eulaliensis Danilo, Remy, Vianey-Liaud, Marandat, Sudre & Lihoreau, 2013; Pa. gaytei Remy, 2015. EXCLUDED SPECIES. ��� Pachynolophus hookeri Hooker, 1994 (synonym of Cymbalophus hookeri Godinot, 1987; see Danilo et al. 2013). EMENDED DIAGNOSIS (after Danilo et al. 2013). ��� Small brachyodont equoids; nasal notch opening above the postcanine diastema, close to canine; confluent foramen ovale and middle lacerate foramen. Usually rather long DPC. Virtually complete set of cheek teeth with occasional lost of P1/ 1 in old individuals. Less bunodont dentition than in hyracotheres, up to fully lophodont. Mesostyle missing on upper molars, sometimes replaced by a ���pseudomesostyle���. Fairly developed conules. Generally weak cingula, less continuous and less high than in hyracotheres, phyletically tending to fade; the labial one frequently interrupted at paracone on upper molars. Non-molariform premolars with phylogenetic trend toward a reduction of their area relatively to molars. P3/-P4/ devoid of hypocone. Postero-lingual expansion of the distal outline of P4/ in some species. Twinned metaconid on lower molars. Large hypoconulid basin on M/3, with labial cristid of hypoconulid directed from entoconid to mid hypolophid. P/3-P/4 devoid of entoconid. NOTE Occasional absence of the first premolar on some specimens (e.g. FSL 3038 [Pa. livinierensis], ICP 3070 [Pa. boixedatensis]) could be ontogenetic in origin. This phenomenon was also observed in the genus Plagiolophus that bears relatively short premolar series like Pachynolophus (Remy 2004: 123). Indeed, many specimens of various Pachynolophus species retain their P1/1, what may be the original condition (e.g. Pa. cesserasicus FSL 2977, Pa. duvali MNHN CGR-82, Pa. lavocati MNHN Qu-7371, Pa. eulaliensis UM-SEL 45, SEL 88, SEL 05, an unpublished skull of Pa. livinierensis in the Vidalenc��� coll.)., Published as part of Remy, Jean A., Krasovec, Gabriel, Lopez, ��ric, Marandat, Bernard & Lihoreau, Fabrice, 2019, The Palaeotheriidae (Equoidea, Perissodactyla, Mammalia) from the Eocene fauna of Aumelas (H��rault department, France), pp. 525-585 in Geodiversitas 41 (13) on page 537, DOI: 10.5252/geodiversitas2019v41a13, http://zenodo.org/record/3699849, {"references":["SAVAGE D.

DP/1)- DP/2-M/3, and (alv. six I and left /C); AUM 1620, left mandible with DP/2-M/2-(M/3); AUM 1627 left mandible with M/2-M/3; AUM 1654, right M/3. DESCRIPTION The two featured upper cheek teeth series, AUM 199 and AUM 1586, are preserved in a very bad condition. AUM 199 which pertains to an old individual, is affected by a deep longitudinal fissure at the level of P3/-M2/ and the loss of ectoloph of M3/. The teeth of AUM 1586 are even more worn and molars partly broken. These specimens and other associated upper cheek teeth present rather conspicuous differences compared to Pachynolophus ruscassierensis n. sp. They are roughly 20% larger than average for most parameters. That would correspond to an estimated length of the row P2/-M3/ of at least 60 mm, and to an estimated weight of 28 kg (instead of 52 mm, 21 kg for Pa. ruscassierensis n. sp.) (Table 4; Appendix 8). As far as we can see, compared to Pa. ruscassierensis n. sp., the molars appear slightly more lophodont. The labial side of ectolophs is more slanted and indicates an IH index slightly lower. Thus the M3/ (AUM 213), although barely worn, has an IH of 0.40, near the lower variation limit of Pa. ruscassierensis n. sp. (Appendix 12). The metaloph of molars, more forwardly oriented, is directed to the distal side of paracone. The cingula are on the whole thinner and likely lower. The distal cingulum of M3/ is nevertheless fairly prominent, and it can give rise to a small hypostyle (AUM 213). The occlusal faces of P3/ and P4/ offer a more defined V shape. P3/ is more squared and has a wider lingual outline and a broader distal basin. In addition, the surface ratio of the premolar sector appears to be slightly lower than that of Pa. ruscassierensis n. sp. Thus, P4/ is somewhat smaller (SP 4/ SM3 = 49 instead of 52-59) and the ratio SP / SM (by combination of two specimens, AUM 199 and AUM 1586), could have reached only 38 to 42 instead of 44-49 (Appendix 21). P2/ is very unlike that of Pa. ruscassierensis n. sp. as it is almost rectangular and possesses two distinct labial cusps. Some mandibular fragments and lower teeth have been assigned to the same taxon on the basis of molar size. The crescents of the molars are rather sharp, not very rounded. The metastylid is not highly developed and poorly separated from metaconid. The ectocingulum is generally thin, variable in height (high on AUM 1599, lower on AUM 1617), and interrupted on cuspids except on AUM 1615. The P/4 (AUM 1599) is molariform, even if it bears only a small knob instead of a true entoconid. Its relative area is low compared to Pa. ruscassierensis n. sp. (Appendix 22). Despite P/3 (AUM 1599) is in a bad condition, we can see that the trigonid is long and tapers mesially. Its prominent protoconid overhangs a somewhat flattened crescent. The talonid is short and low, crossed by a weak ridge that ends in a small hypoconid. DP/4 is fully molariform. On AUM 332, the metastylid is clearly separated from metaconid but slightly lowered. The DP/3 outline slightly tapers mesially and the paralophid bears a tiny lingual accessory cuspid (AUM 1620). DP/2 is simple, with a prominent cusp, overhanging small mesial and distal knobs, with a very short talonid. DP/1 was bi-rooted. Other anatomical data The upper DPC is not preserved. On the mandible AUM 1617, the DPC (considered in that instance as the length /C-DP/2) measures 19.5 mm. With a teeth row length of about 63 mm, the DPC represents 31% of this value. But this specimen is a juvenile and is likely not representative of the adult condition. Due to its size, the mandibular fragment AUM 323 could perhaps be assigned to the same taxon. It shows a symphysal region not reaching alveoli of the P/1, but with both /C and the sockets of incisors. The preserved part of diastema is 24 mm long; assuming at least 6 mm for P/1 length (the DPC being the distance /C-P/2), with a tooth row length of 60 mm (estimation for AUM 199) to 63 mm (AUM 1617), this DPC (24 + 6) should have reached 48 to 50% of LRDJ. The mandibular body is more robust than that of Pa. ruscassierensis n. sp., high from 16 mm under the DPC, to 28 mm under M/3, with a minimal width of 12 to 16 mm at the DPC. On AUM 1617, a single foramen mentale is observed under DP/2. The vertical ramus is unknown. At maxillary level, the anterior opening of the infra-orbital foramen (FIO) is located above anterior half of P3/ (AUM 1586). COMMENTS The generic status of this assemblage needs some comments. It can be a priori assigned to Pachynolophus due to lack of mesostyle on upper molars, lack of hypocone or entoconid on premolars, rather sharp crescents on lower cheek teeth, long DPC. But, one might wonder whether these specimens should not rather refer to Propalaeotherium cf. gaudryi from Aumelas. Indeed, their size is identical, with variation limits overlapping almost exactly. Moreover, we know that some specimens lack mesostyle in Propalaeotherium gaudryi (Remy 2017). On the other hand several features clearly differentiate this cluster. First, the relative surface area of the premolar series seems smaller than in Pr. cf. gaudryi from Aumelas, (actually more alike than data observed in the true Pr. gaudryi !). Thus P4/ is rather small (SP 4/ SM3 = 49 instead of 50-61 in Pr. cf. gaudryi; SP 4/ SM = 18 instead of 19-22). Then, we speculate that the total surface of the premolars represents only 38 to 42% of the surface of the molars instead of 41 to 50% in Pr. cf. gaudryi (Appendices 9; 21 [caption]).

The parastyle of molars is a slightly less prominent. P3/ and P4/ have a more mesially shifted protocone with a broader distal basin. P2/ shows a more rectangular outline, with two more separated labial cusps. The lingual cingula are less developed. The associated mandibular specimens confirm this differentiation with respect to the lineage of Pr. gaudryi. Indeed, the crescents of the lobes of lower cheek teeth are less rounded and more acute. The DPC is likely longer than in Pr. gaudryi where it should not exceed 30 to 32% of LRDJ (Remy 2017). Conversely, we have seen that on the mandible AUM 323, it could have reached 50%. It seems that this set of specimens from Aumelas should not finally be brought close to a Propalaeotherium, and must rather be assigned to the genus Pachynolophus. Compared to Pa. ruscassierensis n. sp., conspicuous differences have been previously highlighted, particularly in size. The size difference with the genotypic species Pa. duvali, which is one of the smaller species of the genus, is even larger and around + 40%. Furthermore, despite some similarities that lead to bring the two forms closer together in a cladistic analysis (see below), the Aumelas specimens are quite distinct from this latter species by their P2/ even more square, their P3/ P4/ more transversely elongated. So, the Aumelas form can not be considered as affine to Pa. duvali. In fact, we are dealing with one of the largest Pachynolophus. Assuming that FSL-2977 could be a good representative of Pa. cesserasicus (see above), the specimens of Aumelas are about 15% larger for most parameters. Conversely, they are 15% smaller than the type and single specimen of Pa. cayluxi. Besides, compared to both species, the upper molars and mostly the P4/ of Aumelas are less bunodont, with ectolophs more flattened. All cingula are thinner and less continuous. P2/ is more quadrangular. Therefore, this Aumelas material probably represents an original new species, but it is too damaged and too poorly known to define a new taxon in the current state.

DESCRIPTION We gather some maxillaries or maxillary fragments of Propalaeotherium, which display differences with Propalaeotherium sudrei and that present larger measurements (Table 2). Indeed the upper cheek teeth row is on average 13% longer (60- 62 mm instead of 54 mm), and the upper molar row is 16% longer (36-38 mm instead of 32 mm). All cheek teeth are on average 10% larger in linear measures. On lower cheek teeth, the length mean difference is of 8% (Appendices 16; 17). Upper teeth areas are about 30% larger (Appendix 10). Lower teeth areas (Appendix 11) show less mean size difference (14%). Most of these differences are significant (p: Pr. sudrei, and it may lack at least on M3/ (AUM 209, AUM 1583). On protoloph, the groove between protocone and paraconule varies in depth. It is deep on the M2/ and M3/ on AUM 209, but it is shallower on other specimens (e.g. AUM 1583). The metaloph, which lacks discernible metaconule, runs first toward the distal side of the paracone, and turns to reach the mesio-lingual side of the metacone. The lingual cingulum is well developed on these molars. Although thin and disrupted in front of the cusps, the cingulum is continuous on some M1/ (AUM 209) and M2/ (AUM 1592), but limited to the medivallum on the M3/ (AUM 168). The distal outline of M3/ is convex, with a strong distal cingulum, which eventually bears small knobs (hypostyle) (AUM 168, AUM 1583). The mean PMI is estimated to 70 (ranging from 68 to 71) and the mean SP / SM surface ratio is 44 (ranging from 41 to 50; Appendix 9). P4/ is transversely elongated (L/ W 0.73 on average). The labial cusps of P4/ are bunodont and close to each other, separated by a groove. The centrocrista is slightly notched and lacks mesostyle. The ectocingulum is continuous, not salient and its external outline is strongly concave. The styles are rather low and variably protruding. The protocone is mesio-distally centered. The paraconule is well defined even if the groove between protocone and paraconule is not deeply notched. The lingual outline is variable, narrow on AUM 192, wider on AUM 1583 with a large posterior basin. On AUM 192 and AUM 1594, there is a small metaconule connected to a curved postprotocrista, a somewhat starry feature. A cingulum encircles the whole internal part of the tooth on most specimens (AUM 192 and AUM 1594), but it is interrupted at the protocone on AUM 1592, AUM 1584, and AUM 168 (very worn). P3/ offers a similar shape but is less transversely elongated; AUM 1584 is almost quadratic. The bunodont labial cusps are slightly tighter than on P4/. They display a labial continuous and concave cingulum. The parastyle is stronger and protrudes outward and forward. It appears weaker on AUM 168 with a metastyle as marked as parastyle. The lingual shape is wider than on P4/. It is even much enlarged on AUM 1584, which is nearly rectangular, with a slightly forwardly shifted protocone. Conversely on AUM 168, the internal contour remains narrow and the protocone is centered. The protoloph is not deeply notched and the paraconule is almost indistinct on AUM 1584 (more individualized on AUM 168). We note the presence of a postprotocrista that lacks a well-defined metaconule. Conversely, the metaconule is well marked on AUM 168, it is low and sinuous on AUM 1584. The lingual cingulum is always interrupted facing the protocone. P2/ seems rather variable. On AUM 168 and AUM 1584, it is a triangular tooth, barely enlarged transversely and tapering forward. On the distal crest of the prominent paracone, which is remote forward, we note the presence of a small but rather individualized low metacone. The ectocingulum is continuous, rather weak, and less thick than on P3/ and P4/. Likewise the styles are weak. The internal part of the tooth is surrounded by a continuous cingulum. A rise of this cingulum, at the widest level of the tooth, evokes a small protocone. On AUM 1584, a tiny knob is present at the place of the metaconule. AUM 1583 shows on the right P2/ a structure according to this description, but the left P2/ is transversely broader, with a well marked protocone and a rather wide posterior basin. P1/, partly preserved on the right side on AUM 1583, is a simple elongated tooth, surrounded by a circular cingulum, its prominent cusp is barely shifted oralwards. The two alveoli of P1/ are also to be seen on AUM 168. On both specimens, there was not any diastema between P1/ and P2/. Ten lower jaw fragments or isolated teeth are related to this taxon (Fig. 7). The teeth are first characterized by their dimensions larger than those of Pr. sudrei (see above). Mor- phologically, this material offers little information to differentiate the taxon compared to other Propalaeotherium, because of the weak characterization of the lower cheek teeth and of individual variations. One can only observe that the crescents of the molars are fairly rounded, and their metaconid are generally well splitted. The labial cristid of the M/3 hypoconulid is connected halfway to the hypolophid. The ectocingulum is quite variably developed. Moreover, P/4 is rather bulbous; its talonid, a bit wider than on Pr. sudrei, is slightly lower than the trigonid; it does not show any hypolophid, but a tiny entoconid is present. P/3 is narrowed mesially and the crescent of the trigonid is very flat. The anterior cingulum lacks paraconid. The protoconid is linked to the metaconid through a very oblique protolophid. The talonid is short and the metalophid is low and oblique disto-labially, free of a well-developed hypoconid. Anterior teeth are not known. Only few observations are available concerning the skull morphology. The alveolus of a rather large and mesio-distally elongated canine is preserved on AUM 168, which was likely pertaining to a male. This allows evaluating relative length of the DPC. It was 21 mm long with a LRDJ of 62 mm, and the % DPC is estimated at 33.9 (Appendix 20A). The obliquity of the nasal opening edge suggests that the notch did not likely exceed the level of P1/. The anterior opening of the infraorbital canal (FIO) is open 9 mm above the alveolar margin, its distal edge is very rostrally located, above the limit P2/-P3/. The morphology of the mandible is also only partly known. The mandibular body is not very high (26 mm under M/3; AUM 1601, AUM 1603) and it seems not to be much lowered under the premolar row. A mental foramen opens under the limit P/3-P/4, and a smaller one under P/1 (AUM 206). The angular process is broad and is not ventrally protruding. The vertical ramus seems to have been high (AUM 1606). COMMENTS As already noticed, this material is significantly larger than that of Pr. sudrei. It is also greater than Pr. voigti (oUK to MK) with differences averaging about +8% in linear measures and about +24% in surfaces (p: Pr. hassiacum and Pr. isselanum. As a result, their measures are only compatible with Pr. gaudryi from the Paris Basin or with the specimens of the Geiseltal uUK usually referred to Pr. voigti. The specimens from Rouzilhac (molassic beds of Issel, Aude, France), recently assigned to the taxon (Godinot et al. 2018) also seem to be about the same size. Actually, with the available material of Aumelas, differences of upper cheek teeth size relative to Pr. gaudryi are negligible. Likewise, as regards lower cheek teeth, the dimensions fall within variation ranges of that taxon (Appendices 16; 17). Great morphological similarities are also observed at Aumelas with Pr. gaudryi. Like in Pr. gaudryi, a mesostyle is not always present on upper molars. The degree of brachyodonty is identical, more marked than on Pr. sudrei (Fig. 4). The enamel appears rather thick. Besides, we find as in Pr. gaudryi the great development of the parastyle of upper molars, the usually moderate splitting of the protoloph. The shape of the premolars P3/ and P4/ is similar, they are more transversally elongated than on Pr. sudrei. Moreover we may observe on P4/ a metaconule distally connected to the postprotocrista as on some specimens of Pr. gaudryi (NMB TS-83). Like in Pr. gaudryi, P2/ bears two distinct labial cusps. Its shape is rather variable, from triangular, anteriorly tapering, to almost quadratic. The material of the Geiseltal uUK up to now referred to as ��� Pr. voigti ��� (see above), which presents great similarities with these specimens, might also be close to Pr. gaudryi. Nevertheless, the Aumelas material differs from Pr. gaudryi by several features that prevent a complete assimilation to this species, in the current state of knowledge. First, the relative surface of upper premolar area seems slightly greater (although the difference be not significant, failing sufficient documentation, and due to the variability of P2/). Thus the SP 4/ SM3 ratio reaches 54 (50 to 61) instead of 51 (49 to 54) for Pr. gaudryi). The material of Rouzilhac presents values close to those of Aumelas: the same ratio is 56 on the maxillary RZ-221 (Godinot et al. 2018: fig. 40-a). Then the lingual cingula are slightly less marked than with typical Pr. gaudryi, notably on premolars, and finally there is no P1/-P2/ diastema. These observations would attest to the slightly more progressive nature of the form of Aumelas (as well as that of Rouzilhac material, also recognized by the authors of the monograph) compared with Propalaeotherium gaudryi from the Paris basin. urn:lsid:zoobank.org:act: F10B45D3-0CC9-4CD4-8E38-0C568BBC7038 Finally, the Aumelas material could be closer to the taxon of Rouzilhac than to that latter.

La ville, lieu d'émancipation, d'intégration ou d'exclusion pour les femmes ? La recherche scientifique actuelle, si préoccupée du phénomène urbain, n'a pas développé de réflexion systématique sur les relations qui se sont tissées au cours des siècles entre les femmes et la ville, comme si les femmes n'avaient pas modelé leurs lieux et leurs espaces de vie. L'ouvrage ne prétend pas combler cette lacune mais participe à une première approche, historique et sociologique, amorcée au début des années 1990 et qui a suscité des travaux parallèles, notamment en France. Très vite, on le verra, l'essentiel des contributions historiques concerne le statut économique des femmes. L'émancipation par le travail - le travail reconnu et salarié - est une donnée essentielle, tandis que l'occultation de leurs activités non marchandes explique le silence de l'histoire sur leur place dans la cité. Regards d'historiennes et d'historien qui s'interrogent sur la ville et les femmes mais aussi réflexions de sociologues face aux nouveaux problèmes qui naissent de l'urbanisation, des changements profonds de la ville - de la grande ville surtout. Le débat n'est tranché, ni entre eux ni dans l'ouvrage. Il reste très largement ouvert et témoigne de la fécondité de la problématique originelle : la ville, un lieu d'exclusion ou un lieu d'émancipation pour les femmes?

Fruit de l'initiative des Facultés universitaires Saint-Louis, le présent ouvrage rend hommage, à l'occasion de son admission à l'éméritat, à Jacques Dabin qui fut titulaire de cours de philosophie morale et de droit naturel depuis 1968 et assura la fonction de Recteur des Facultés de 1973 à 1993. Reflétant à la fois ses préoccupations majeures, ainsi que la diversité des approches correspondant aux différentes composantes des Facultés, cet ouvrage réunit les actes du colloque que les Facultés ont consacré à ce thème du 20 au 22 avril 1994, ainsi que d'autres contributions émanant de membres ou amis des Facultés qui ont accepté de se joindre à cet hommage.

Le regard à partir des sciences humaines ouvre simplement une perspective latérale, par rapport à une réflexion sur le sens de notre vie humaine et chrétienne. Toutefois les analyses sociologiques peuvent aider à dégager la signification de la notion de Providence dans un contexte marqué par un sentiment de crise sociale, voire de catastrophe. Notre réponse comprendra deux temps. Dans le corps du texte, nous nous limiterons à un point de vue d’analyste. En finale, nous réagirons en chrétien q...

Introduction Les membres du personnel des crèches et des hôpitaux chrétiens définissent-ils leurs activités professionnelles ainsi que les objectifs de l’institution qui les emploie en référence à l’identité chrétienne ? Comment s’opèrent les transactions entre les divers membres du personnel (direction d’une crèche et puéricultrices, responsable du nursing d’un hôpital et infirmières...) lorsque l’identité chrétienne de l’institution est en jeu ? Comment est-elle éventuellement utilisée par ...

Plus que d’autres analyses sociologiques, les recherches orientées en vue de comprendre le changement social sont marquées au moins implicitement par un souhait que les résultats aient une valeur prédictive. De quelle manière la compréhension de la situation actuelle en liaison avec une évolution antérieure permet-elle de dégager les lignes de tendance et les points de rupture qui vont façonner l’avenir ? L’actualité et son statut analytique Une question clé, révélatrice de la position théori...

Depuis un certain temps les usagers acquièrent assez de légitimité pour s’imposer comme un acteur porteur d’un intérêt collectif réclamant un droit d’intervention. Dans la mesure où une telle transformation s’opère, les offreurs de service ne sont plus simplement face à des utilisateurs réagissant individuellement, mais ils doivent tenir compte de groupes constitués pour la défense collective d’un intérêt. Dotée d’une légitimité en référence à une conception renouvelée du bien commun, cette a...

De halfnatuurlijke landschappen zijn randgebieden, tussengebieden. Het doel van het onderzoek dat wij instellen is de talrijke aspecten van hun “marginale” status onder de aandacht te brengen; de inzet van de behandeling die hen zal ten deel vallen is het behoud van het potentieel dat zij herbergen en van de vele gebruiksmogelijkheden waarvoor zij in aanmerking komen. Verscheiden zijn de halfnatuurlijke landschappen reeds door de namen die ze worden gegeven. “Landschappen” of “halfnatuurlijke...

Le Séminaire interdiscipli­naire d'études juridiques des Facultés universitaires Saint-Louis a suscité la collaboration de juristes et de spécialistes des sciences humaines (histoire, économie, sociologie, psychologie, science administrative, philosophie) afin d'éclaircir les rapports multiples entre les notions de droit et d'intérêt. Ce thème s'est révélé si fécond qu'il est apparu nécessaire de publier les résultats de ces travaux dans trois volumes distincts. Le présent volume, premier de cette série, regroupe d'abord un ensemble de contributions qui précisent le sens et le rôle de la notion d'intérêt selon diverses perspec­tives scientifiques. Il contient ensuite des recherches de philosophie du droit qui concernent la légitimité des normes juridiques en rapport avec l'idée d'intérêt. Il présente enfin des études de théorie générale du droit qui portent sur les relations entre l'intérêt et les catégories juridiques de droit subjectif et de loi.

La signification de la ville a été affectée par des mouvements de fond qui la travaillent sur de longues périodes. Ces évolutions sont progressives. On peut en trouver de nombreux indices, notamment des le XIXème siècle. A un certain moment, ces évolutions ont atteint un effet seuil avec des ruptures d'équilibre qui modifient globalement le régime d'échanges entre les diverses composantes de la vie sociale. Il ne s'agit pas de déterminer la part des actions féminines à cette transformation où...

Dans le cadre d'un thème, comme faire revivre la ville, il convient d'abord de prendre distance et de se demander : "qu'est-ce que la ville ?". La définition est-elle associée à un mode d'appropriation territoriale et celui-ci évolue-t-il avec le développement de ce que nous appellerons le processus d'urbanisation. Nous partons de l'hypothèse que la ville est susceptible d'une pluralité de définitions dont il n'est pas sûr qu'elles renvoient à la même réalité empirique. Nous allons ainsi prop...

La loi, qui a peut-être été trop célébrée à une certaine époque, n'a pas bonne presse dans l'éthique chrétienne actuelle, c'est le moins qu'on puisse dire, puisque certains n'hésitent pas à l'en bannir purement et simplement. Il s'agit cependant d'une notion et d'une réalité fondamentales dont il faudrait redécouvrir la fonction constitutive pour l'agir humain en général et pour l'agir chrétien en particulier. Cet ouvrage veut y disposer par une réflexion pluridisciplinaire qui fait appel à la philosophie, au droit, à la sociologie, à l'exégèse, à la psychanalyse et à la théologie, en vue d'éclairer quelque peu la signification du concept de loi et, par conséquent, la fonction que celle-ci joue dans l'éthique chrétienne.

Les sites semi-naturels sont des espaces-lisières. Des espaces d’entredeux. L’objet des recherches qu’on entame est de mettre en lumière les multiples aspects de leur statut “marginal” ; l’enjeu du sort qui leur sera réservé est de garantir les virtualités qu’ils recèlent et la multiplicité des usages dont ils sont susceptibles. Divers, les espaces le sont déjà par les noms qu’on leur donne. “Sites” ou “espaces semi-naturels”, dit-on, mais ces appellations sont récentes et d’origine scientifi...

Le problème des relations, voire des tensions entre l’éthique personnelle et l’éthique collective sera abordé sous l’angle particulier d’une sociologie de l’espace social. Cela nous mettra d’emblée au cœur d’enjeux contemporains : les migrations, les régionalismes, l’ethnicité face aux mécanismes de solidarité basés sur l’Etat-nation. La mise au jour d’un certain nombre de présupposés d’une sociologie des spatialités aboutira à des interrogations sur les échanges entre sociologie et philosoph...

La méthode La méthode qui vient d’être proposée va être appliquée au texte du Cardinal Danneels. Le texte ayant déjà été analysé par F. Houtart, la comparaison permettra de mieux saisir les limites de pertinence des deux techniques et leur lien privilégié avec un objectif de recherche. Dans le cas présent, nous voudrions mettre en évidence le lien entre la technique d’analyse et l’explication des symboliques sociales. Ceci permettra de faire ressortir l’importance que revêt le récit de quête,...

Ce volume présente les résultats d’un séminaire portant sur la comparaison de quatre méthodes d’analyse de contenu à caractère qualitatif. Ce séminaire organisé par le Centre d’études sociologiques des Facultés universitaires Saint-Louis, s’est déroulé en plusieurs étapes : chaque analyste a présenté sa méthode devant le groupe de chercheurs. En fin d'année, les quatre analystes se sont retrouvés dans un colloque d’une journée réunissant une centaine de participants. Les apports de chacun ont...
