Lymphoid tyrosine phosphatase (LYP) and C-terminal Src kinase (CSK) are negative regulators of signaling mediated through the T cell antigen receptor (TCR) and are thought to act in a cooperative manner when forming a complex. Here, we show that dissociation of the LYP/CSK complex is necessary for recruitment of LYP to lipid rafts, where it down-modulates TCR-mediated signaling. Our findings may also explain the reduced TCR signaling associated with a single nucleotide polymorphism, which confers increased risk for autoimmunity and results in the expression of a LYP allele that can no longer bind CSK. Development of a potent and selective chemical probe of LYP allowed us to confirm that the observed down-modulation of TCR-induced signaling was due to the LYP catalytic activity. Our compound also represents a starting point for the development of a LYP-based treatment of autoimmunity. [less ▲]

The many recently published data on vitamin D have raised much interest in the medical community. One of the consequences has been a great increase in the prescription of vitamin D concentration measurements in clinical practice. It must be reminded that only the measurement of 25-hydroxyvitamin D (25(OH)D) concentration is indicated to evaluate vitamin D status. Furthermore, since vitamin D insuffi ciency is so common, since treatment is inexpensive and has a large safety margin, and since we already have much data suggesting that besides its classic effects on bone and mineral metabolism, vitamin D may potentially be helpful for the prevention/management of several diseases, perhaps should it be prescribed to everyone without prior testing? In our opinion, there are however groups of patients in whom estimation of vitamin D status is legitimate and may be recommended. This includes patients in whom a “ reasonably ” evidence-based target concentration (i.e., based on randomized clinical trials when possible) should be achieved and/or maintained such as patients with rickets/osteomalacia, osteoporosis, chronic kidney disease and kidney transplant recipients, malabsorption, primary hyperparathyroidism, granulomatous disease, and those receiving treatments potentially inducing bone loss. Other patients in whom vitamin D concentration may be measured are those with symptoms compatible with a severe vitamin D defi ciency or excess persisting without explanation such as those with diffuse pain, or elderly individuals who fall, or those receiving treatments which modify vitamin D metabolism such as some anti-convulsants. Measurement of Vitamin D concentrations should also be part of any exploration of calcium/phosphorus metabolism which includes measurement of serum calcium, phosphate and PTH. [less ▲]

The paper singles out the key roles of US equity skewness and kurtosis in the determination of the market premia embedded in Hedge Fund returns. We propose a conditional higher-moment asset pricing model with location, trading and higher-moment factors in order to describe the dynamics of the Equity Hedge (Market Neutral, Short Selling and Long/Short strategies), Event Driven, Relative Value, and Funds of Hedge Funds styles. The volatility, skewness and kurtosis implied in the US options markets are used by Hedge Fund managers as instruments to anticipate market movements. Managers should adjust their market exposure in response to variations in the implied higher moments. We show that higher-moment premia improve a conditional asset pricing model both in terms of explanatory power (R-squares and Schwarz criterion) and specification errors across all Hedge Fund styles.

On the ground of a three years-long multi-sited, ethnographic research conducted in Southern Nigeria, Italy and the United Kingdom, my PhD dissertation analyzes the processes of transnationalization that have affected the southern Nigerian video film industry (Nollywood) during the first decade of the 2000s, and interpret their significance in relation to the industry’s history and recent developments. Transnationalization processes have affected the industry at different levels, which include its economic and social organization, its international representation, and the narrative and aesthetic features of the films it produces. The dissertation analyzes these different levels through three separated, but interrelated, sections: 1) The Nigerian video industry has experienced a transnational success since its early stages. Thanks to the informality of Nollywood’s network of distribution, pirated copies of Nigerian videos have circulated throughout the world since the mid 90s. Informal and pirated networks of circulation made videos travel long distances and create for the industry a wide transnational audience. However, as this section argues, informal production and distribution strategies and their vulnerability to piracy progressively eroded the industry’s economy. This section then argues that, once the internal Nigerian video market has started to implode because of the excess of informality and the lack of a proper distribution framework, an important section of the industry has explicitly decided to target the transnational audience generated by the global informal circulation of Nigerian video films. New modes of production and circulation emerged, which mainly target local elites and diasporic audiences. A new wave of high budget productions saw the light. The videos’ patterns of mobility transformed and, this impacted on video films’ economic accessibility for local popular audiences. 2) The second section analyzes the way videos’ discursive circulation (that is, the way in which videos, and the video phenomenon in general, have been portrayed, discussed and analyzed both in Nigeria and elsewhere) impacted on the video industry’s transformation. As with the material and economic circulation analyzed in the first section, videos’ discursive circulation interacted with the video phenomenon in at least two ways. On the one hand it made videos travel. It made them cross boundaries and reach audiences they did not even envisaged to reach. On the other hand, it opened for the video industry a field of dynamic confrontation. Nollywood has been compared to other global film industries (such as Bollywood and Hollywood), and it has been criticized for its low production quality standards. The video phenomenon has been celebrated for some of its achievement, and mocked for some of its weaknesses. This complex interaction with the global cinema arena has produced numerous effects on the video industry. Videos entrepreneurs reacted to criticism and engaged into active processes of transformation aimed at making the video industry reach international production quality standards, and escape the marginal position within which much of the mentioned discursive constructions positioned it. 3) The third section looks at videos’ aesthetics and narrative structures. The transnational mobility of the videos impacted on them in multiple ways. On the one hand, as a result of the encounter of both transnational and local aesthetic and narrative aspects, videos developed a particular aesthetic and narrative openness which made them able to address dispersed audiences and reconstitute them into a pan-African public. Through their specific film language, contents, and forms of address videos activated a debate on what it means to be African today, and shaped it around the social, cultural and historic specificities of the post-colonial, post-Structural-Adjustment era in Nigeria and, more generally, in sub-Saharan Africa. On the other hand, mobility intervened in the reformulation of videos’ narrative and aesthetic patterns. The video phenomenon has been adopted and reinterpreted by Nigerian diaporic groups in Europe and elsewhere. The specific social and economic conditions associated with the experience of living in the diaspora interacted with the videos’ production strategies and defined particular narrative and aesthetic solutions. When the Nigerian video industry entered the production crisis diasporic production companies found themselves in the position of an avant-garde in what concerns the industry’s transnational expansion: they had already experimented with economic and aesthetic solutions that could open Nigerian productions to global audiences. As a result, they became the bridge able to connect the Nigerian video film industry to transnational, non-African audiences. [less ▲]

The text is related to the calculus’s main theorem learning as it is studied by students in the last year of Belgium secondary school. We make an epistemological analysis of the theorem that inspired us the set up of a situation composed of four mathematics statements and for which we need rectilinear movements with or without variable speeds, speeding and moving laws, areas, volumes and flows. The suggested strategies for these statements and the reactions will be analysed later. [less ▲]

Ce chapitre vise à présenter les règles juridiques qui déterminent le rythme électoral. Il commence par une courte discussion sur la question de savoir quel laps de temps peut être considéré comme une durée raisonnable pour une législature. Il se poursuit par le passage en revue les normes qui établissent, pour chacune des assemblées élues du pays, la durée qui sépare en principe deux élections , et par l'examen des cas où la législature est écourtée par l’organisation d’élections anticipées. Enfin, le chapitre s'achève par une brève réflexion sur l’opportunité d’une synchronisation des différentes échéances électorales. [less ▲]

The oxygen nightglow emissions of Venus: vertical distribution and role of collisional quenching J.-C. Gérard (1), L. Soret (1), A. Migliorini (2), G. Piccioni (2), and P. Drossart (3) (1) LPAP - Université de Liège - Belgium (jc.gerard@ulg.ac.be, 0032 4 366 9711), (2) INAF - Rome, Italy, (3) LESIA, Observatoire de Paris - Meudon, France Three-body recombination of atomic oxygen produces O2 molecules excited in different electronic states such as a 1∆g, b 1 􏰀+g , A 3 􏰀+u , c 1 􏰀uand A’ 3∆u, each with a specific quantum efficiency. When they radiate, optical transitions are observed in a wide range of wavelengths extending from the ultraviolet to the near infrared. In planetary atmospheres, spontaneous radiative deexcitation compete with collisional quenching with ambient molecules and atoms. As a consequence, the corresponding airglow emission profiles may significantly differ from each other in brightness and altitude of the emitting layer. We model the volume emission rates and limb profiles of the O2 Atmospheric Infrared (a 1∆-X 3 􏰀), Herzberg I (A 3 􏰀-X 3 􏰀), Herzberg II (c 1 􏰀-X 3 􏰀), Chamberlain (A’ 3∆-a 1∆) bands expected on the Venus night side. The quenching rates are taken from laboratory and observational planetary data and we apply two different methods to determine the oxygen and CO2 density profiles. One is based on recent analysis of data collected by instruments on board the Venus Express mission. The second one uses a one-dimensional chemical-diffusive model where the free parameters are the strength of turbulent transport and the downward flux of O atoms. Both approaches indicate that the calculated intensities of each transition range over several orders of magnitude and that differences are expected in the altitude of the maximum emission. These predictions will be compared with VIRTIS/Venus Express limb observations, which make it possible to derive the vertical distribution of the O2 emissions in the visible and infrared. These measurements suggest that no difference is observed between the altitude of the peak of the IR Atmospheric and Herzberg II bands. Conclusions will be drawn about the validity of the current set of quenching coefficients used in the model. [less ▲]
