In this chapter we develop an agenda for future research on the personalization of politics. To do so, we clarify the propositions of the personalization hypothesis, critically discuss the normative standard on which most studies base their evaluation of personalization, and systematically summarize empirical research findings. We show that the condemnation of personalization is based on a trivial logic and on a maximalist definition of democracy. The review of empirical studies leads us to question the assumption that personalization has steadily increased in all areas of politics. Finally, our normative considerations help us develop new research questions on how personalized politics affects democracy. Moreover, this review also makes clear that another weakness of today's empirical research on the personalization of politics lies in methodological problems and a lack of analysis of the impacts of systemic and contextual variables. Consequently, we suggest methodological pathways and possible explanatory factors for the study of personalization.
Human mimicry
(2009)
Human mimicry is ubiquitous, and often occurs without the awareness of the person mimicking or the person being mimicked. First, we briefly describe some of the major types of nonconscious mimicry -verbal, facial, emotional, and behavioral- and review the evidence for their automaticity. Next, we argue for the broad impact of mimicry and summarize the literature documenting its influence on the mimicry dyad and beyond. This review highlights the moderators of mimicry as well, including the social, motivational, and emotional conditions that foster or inhibit automatic mimicry. We interpret these findings in light of current theories of mimicry. First, we evaluate the evidence for and against mimicry as a communication tool. Second, we review neuropsychological research that sheds light on the question of how we mimic. What is the cognitive architecture that enables us to do what we perceive others do? We discuss a proposed system, the perception-behavior link, and the neurological evidence (Le., the mirror system) supporting it. We will then review the debate on whether mimicry is innate and inevitable. We propose that the architecture enabling mimicry is innate, but that the behavioral mimicry response may actually be (partly) a product of learning or associations. Finally. we speculate on what the behavioral data on mimicry may imply for the evolution of mimicry.
Agglutinated foraminiferal assemblages from the Oligocene section of an exploration well drilled in the distal part of the Congo Fan are fully documented and interpreted for palaeoenvironment. A total of 65 ditch cutting samples were analysed at 10 m intervals, from 3630 to 4270 m below rotary table. An average of 170 specimens were extracted per sample, with over 100 species being documented and described using SEM and light photography. The results reveal the most taxonomically diverse deepsea Oligocene fauna yet described. Six assemblages have been defined and analysed with Correspondence and 'Morphogroup' Analysis. These are 1. Nothia robusta / Reticulophragmium Assemblage (4110-4270 m), 2. Nothia robusta / Scherochorella congoensis / Discammilloides sp. 1 Assemblage (4000-4100 m), 3. High diversity Reticulophragmium Assemblage (3870-3990 m), 4. Portatrochammina profunda Assemblage (3790-3860 m), 5. Nothia latissima Assemblage (3730-3780 m) and 6. Low abundance Assemblage (3630-3720 m). Palaeobathymetric estimates range from middle -lower bathyal based on comparison with living taxa and morphogroup distributions. These results extend the known stratigraphic range (last occurrences) of Reticulophragmium amp/eetens into the Oligocene in the Atlantic, and possibly also Paratrochamminoides gorayskii, Paratrochamminoides olszewskii, Trochamminoides aff. proteus, Trochamminoides subcoronatus, Haplophragmoides horridus and Haplophragmoides walteri, although reworking is documented with these species. Results also extend the known first occurrences of Recurvoides azuaensis, Spiropsammina primula, Cyclammina aff. orbicularis, Discamminoides sp. and Glaphyrammina americana into the Oligocene. Large scale variations within faunas are largely assigned to documente d variations in sand content, where higher proportions of sand generally coincide with reduced diversity and abundance along with a dominance of opportunistic species such as Nothia robusta, Nothia latissima and Ammodiscus latus. A major excursion in the infaunal morpho group, suspension-feeding morpho group and diversity and abundance within Assemblage 2 is termed the 'Scherochorella Event', and does not correlate with an increase in sand. This fauna is thought to be the result of lower oxygen conditions allowing the dominance of the low oxygen morphotype Scherochorella congoensis and the opportunistic species Nothia robusta. Deep-water circulation in the Atlantic at this time is generally thought to have been strong, and this event suggests that there may have been a temporary expansion of the oxygen minimum zone during the Late Oligocene, coinciding with increased benthic 8180 values, global cooling, and increased upwelling associated with a stronger polar front. The otherwise high diversity of the fauna in the well supports the interpretation of well-oxygenated conditions.
The region of Talmont-Saint-Hilaire (Vendée, France), located at the contact between the Armorican Massif, the Aquitanian Basin and the Atlantic Ocean, has been studied by many geologists and geographers, over the last three centuries. In the years 1780, silver was mined from the sulphide-bearing ore that occurs at the base of the Jurassic limestones. The stratigraphy of the latter sediments, as well as their relationship with the hercynian basement, was investigated during the 19th and 20th centuries, mainly by Rivière, the author of the first geological map of the area (1838), Cossmann, Vasseur, Péneau, Ters and Butel. As for Gabilly, he considered the anse Saint-Nicolas as a para-stratotype of the Toarcian. A few Authors, mainly Bocquier and Ters, also studied the evolution of the Atlantic coast during Quaternary. They evidenced remnants of several surfaces fashioned by marine abrasion, the age of which was constrained by archaeological studies. In 1963, Gilbert Bessonnat discovered dinosaur footprints, which, however, had already been observed by Bocquier in the years 1930. Montenat and Lapparent studied the occurrence, which proved to be one of the richest in Europe.
In the Talmondais (Vendée) the Hettangian sedimentation locally begins with fluviatil clastic deposits prior to the deposition of shallow marine carbonates. These clastics, including the footprint-bearing beds of Le Veillon (south of Talmont- Saint-Hilaire) are subject to important and frequent variations in thickness. Drilling and geophysic data indicate a tectonic control of these variations. A fault-block pattern is proposed. At a small scale, it gives an illustration of the extensional tectonic processes related to the evolution of the Biscay rift during the early Liassic.
