Practices of legal and bureaucratic categorisation, as well normative practices of naming are key within the endless construction and reinvention of nation-states. Such practices are part of larger and complex configurations of power along with institutions, more or less formal-informal practices of social control and governing. Today’s production and circulation of categories such “illegal migrant”, “refugee”, “young delinquent”, etc. need to be thought of in relation to categories such as “the national citizen” and the core values and principles attached to such categories. In this paper, I will explore how the dialectics of legality-illegality ─ and practices of visibilisation and invisibilisation ─ can be problematized in relation to a dual process: the ritual affirmation of the Party-state authority and the identity formation of rural migrant workers in South-China. I will argue that such politics ought to be read within the political economy of South-China or what Lee Ching-Kwan has called “decentralized legal authoritarianism” (Lee 2007). By looking at the production and circulation of the category of “the three no’s” (sanwu), I will show that the ambiguity and the flexibility of how this category is used is central in order to account for its symbolic and performative power.

Transmission is a matter of life or death for pathogen lineages and can therefore be considered as the main motor of their evolution. Gammaherpesviruses are archetypal pathogenic persistent viruses which have evolved to be transmitted in presence of specific immune response. Identifying their mode of transmission and their mechanisms of immune evasion is therefore essential to develop prophylactic and therapeutic strategies against these infections. As the known human gammaherpesviruses, Epstein-Barr virus and Kaposi's Sarcoma-associated Herpesvirus are host-specific and lack a convenient in vivo infection model; related animal gammaherpesviruses, such as murine gammaherpesvirus-68 (MHV-68), are commonly used as general models of gammaherpesvirus infections in vivo. To date, it has however never been possible to monitor viral excretion or virus transmission of MHV-68 in laboratory mice population. In this study, we have used MHV-68 associated with global luciferase imaging to investigate potential excretion sites of this virus in laboratory mice. This allowed us to identify a genital excretion site of MHV-68 following intranasal infection and latency establishment in female mice. This excretion occurred at the external border of the vagina and was dependent on the presence of estrogens. However, MHV-68 vaginal excretion was not associated with vertical transmission to the litter or with horizontal transmission to female mice. In contrast, we observed efficient virus transmission to naive males after sexual contact. In vivo imaging allowed us to show that MHV-68 firstly replicated in penis epithelium and corpus cavernosum before spreading to draining lymph nodes and spleen. All together, those results revealed the first experimental transmission model for MHV-68 in laboratory mice. In the future, this model could help us to better understand the biology of gammaherpesviruses and could also allow the development of strategies that could prevent the spread of these viruses in natural populations.

Illusory recollection is the subjective detailed feeling of remembering that sometimes accompanies false remembering of events that never happened (e.g., high confidence, “Remember” judgements, or even remembrance of precise details supposedly associated with the false event). In this review, typical illusory recollection measures obtained from laboratory studies will be depicted, with a focus on the DRM paradigm (Deese, 1959; Roediger & McDermott, 1995), one of the most largely used procedures to study memory distortion and its associated illusory recollection. The theoretical explanations of illusory recollection will be described and contrasted in light of factors affecting the phenomenon, in order to shown their strengths and limits. Although the focus on the origins of illusory recollection is relatively recent, overall, this review suggests that DRM false memories can be an excellent tool to study this phenomenon under controlled conditions and to gain insights on false memories occurring in everyday life.

A scanning light microscope (SLM) is used to illustrate recent benthic foraminiferal species from surface sediment samples collected in Bermuda subtropical environments. Species illustrated here are the main foraminiferal species found in Bermuda lagoons, reefs, caves, mangroves, and ponds, but also occur in most subtropical and tropical areas. The SLM permits photography of specimens without coating and gives pictures most similar to specimens that micropaleontologists see under a dissecting reflected light microscope in a petri dish with water, in contrast to images made with scanning electron microscopes. These pictures are the first SLM illustrations of subtropical/tropical species of benthic foraminifera and will be very useful for their identification. Bermuda recent sediment hosts a benthic foraminifera fauna as diverse as in other subtropical and tropical areas, and the general trends of foraminiferal distribution and morphology are similar. Remarks on foraminiferal distribution in Bermuda and other subtropical/tropical areas are also presented. [less ▲]

Major and trace element XRF and in situ LA-ICP-MS analyses of ilmenite in the Tellnes ilmenite deposit, Rogaland Anorthosite Province, SW Norway, constrains a two stage fractional crystallization model of a ferrodioritic Fe-Ti-P rich melt. Stage 1 is characterized by ilmenite-plagioclase cumulates, partly stored in the lower part of the ore body (Lower Central Zone, LCZ), and stage 2 by ilmenite-plagioclase-orthopyroxene-olivine cumulates (Upper Central Zone, UCZ). The concentration of V and Cr in ilmenite, corrected for the trapped liquid effect, (1) defines the cotectic proportion of ilmenite to be 17.5 wt% during stage 1, and (2) implies an increase of D VIlm during stage 2, most likely related to a shift in fO2. The proportion of 17.5 wt% is lower than the modal proportion of ilmenite (ca. 50 wt%) in the ore body, implying accumulation of ilmenite and flotation of plagioclase. The fraction of residual liquid left after crystallization of Tellnes cumulates is estimated at 0.6 and the flotation of plagioclase at 26 wt% of the initial melt mass. The increasing content of intercumulus magnetite with stratigraphic height, from 0 to ca. 3 wt%, results from differentiation of the trapped liquid towards magnetite saturation. The MgO content of ilmenite (1.4–4.4 wt%) is much lower than the expected cumulus composition. It shows extensive postcumulus re-equilibration with trapped liquid and ferromagnesian silicates, correlated with distance to the host anorthosite. The Zr content of ilmenite, provided by in situ analyses, is low (<114 ppm) and uncorrelated with stratigraphy or Cr content. The data demonstrate that zircon coronas observed around ilmenite formed by subsolidus exsolution of ZrO2 from ilmenite. The U-Pb zircon age of 920 ± 3 Ma probably records this exsolution process.

The Rogaland Anorthosite Province comprises three major massif-type anorthosites, two smaller-sized anorthositic-leuconoritic bodies, as well as a large layered, dominantly noritic intrusion. A mangero-noritic intrusion is found in the northeastern part of the province and major acidic intrusions are located to the far southeast. The Rogaland Anorthosite Province was emplaced into the Sveconorwegian orogenic belt of southwest Scandinavia at 931±3 Ma. Emplacement took place at around 5.5 kbar producing a thermal aureole with osumilite and pigeonite isograds and evidence for dehydration melting. The early history of the hosting terrane most likely dates back to Gothian or late Pre-Gothian times and contain evidence for numerous episodes of folding and deformation. Contact metamorphism was superimposed on a crustal volume, which had been exposed to Sveconorwegian granulite facies metamorphism between 1024 and 970 Ma. Deformation patterns, mineral compositional considerations and geothermobarometry imply that the Rogaland anorthosites crystallized along a P-T trajectory starting at 10-13 kbar, and were emplaced in a mushy state. The possibility that primitive jotunites may be parental to the andesine anorthosites have recently been substantiated, and experimental data show that these jotunites most likely formed by melting of gabbronoritic sources in the lower crust. The 230 km2 Bjerkreim-Sokndal Layered Intrusion also derive from jotunitic parents, and jotunites form a continuous liquid line of descent filling the gap between basic and acidic rocks in Rogaland. This intrusion contains a >7000 m thick layered cumulate sequence, consisting of virtually all the rock types belonging to the anorthosite kindred. The intrusion morphology, layering and compositional variation result from a variety of magma chamber processes, which are discussed in detail. The Rogaland Anorthosite Province also hosts numerous Fe-Ti oxide deposits of variable size, grade and composition. The oxide deposits have been divided into three basic types based on their oxide-phosphate association; type 1: ilmenite-only, type 2: ilmenite + magnetite and type 3: ilmenite + magnetite + apatite. This excursion guide provides detailed itineraries to most parts of the Rogaland Anorthosite Province, with in-depth descriptions of more than 40 key localities, The itineraries cover the various anorthosites, the Bjerkreim-Sokndal Layered Intrusion, jotunitic and acidic intrusions, the hosting metamorphic complex, as well as Fe-Ti oxide and sulfide deposits.

In the framework of the International Liquid Mirror Telescope (ILMT) project, a new method for testing the optical quality of liquid mirrors has been developed. The optical quality of liquid mirrors may be affected by the presence of wavelets in the liquid layer. This talk explains how it is possible to detect these defects by measuring the deflection they induce to a laser beam reflected on the liquid surface. Moreover, this method allows to characterize the different parameters of the wavelets, making possible to simulate their impact on the point spread function of the ILMT. Focus will be done on the experimental setup of the method. [less ▲]
