[more ▼]We report the discovery from the WASP survey of two exoplanetary systems, each consisting of a Jupiter-sized planet transiting an 11th magnitude (V) main-sequence star. WASP-104b orbits its star in 1.75 d, whereas WASP-106b has the fourth-longest orbital period of any planet discovered by means of transits observed from the ground, orbiting every 9.29 d. Each planet is more massive than Jupiter (WASP-104b has a mass of 1.27±0.05 MJup, while WASP-106b has a mass of 1.93±0.08 MJup). Both planets are just slightly larger than Jupiter, with radii of 1.14±0.04 and 1.09±0.04 RJup for WASP-104 and WASP-106 respectively. No significant orbital eccentricity is detected in either system, and while this is not surprising in the case of the short-period WASP-104b, it is interesting in the case of WASP-106b, because many otherwise similar planets are known to have eccentric orbits.

[more ▼]Colour-magnitude diagrams form a traditional way of presenting luminous objects in the Universe and compare them to each others. Here, we estimate the photometric distance of 44 transiting exoplanetary systems. Parallaxes for seven systems confirm our methodology. Combining those measurements with fluxes obtained while planets were occulted by their host stars, we compose colour-magnitude diagrams in the near and mid-infrared. When possible, planets are plotted alongside very low-mass stars and field brown dwarfs, who often share similar sizes and equilibrium temperatures. They offer a natural, empirical, comparison sample. We also include directly imaged exoplanets and the expected loci of pure blackbodies. Irradiated planets do not match blackbodies; their emission spectra are not featureless. For a given luminosity, hot Jupiters' daysides show a larger variety in colour than brown dwarfs do and display an increasing diversity in colour with decreasing intrinsic luminosity. The presence of an extra absorbent within the 4.5 $\mu$m band would reconcile outlying hot Jupiters with ultra-cool dwarfs' atmospheres. Measuring the emission of gas giants cooler than 1000 K would disentangle whether planets' atmospheres behave more similarly to brown dwarfs' atmospheres than to blackbodies, whether they are akin to the young directly imaged planets, or if irradiated gas giants form their own sequence.

[more ▼]Why is it so difficult to talk about China in a nuanced and contrasting manner without falling back on superlatives and generalisations? In about thirty years, China’s GDP per capita has multiplied by eight. From a marginal economic power during the Maoist period (1949-1978), China is now ranked tenth in terms of global economic weight. “Wealth and power” (fu qiang) is the expression that embodies China’s quest for modernity since the second half of the 19th century, when China was still under the yoke of the West. This ambition is still at the heart of the “Chinese dream of rejuvenation of the Chinese nation” dear to Xi Jinping, which he set out during the Third Plenum of the 18th Central Committee of the Chinese Communist Party. But focusing only on this vision of “wealth and power” takes us back to one of the most common ways of representing China: reducing the ongoing socio-economic changes and dynamics to a set of numeric values, ultimately reified and homogenised. The increased power and internationalisation of the Chinese economy has prompted a combination of worry and enthusiasm. What does this imply about the paradigm shift in the way we portray this country? Perhaps it is still hard to leave behind the image of a subordinate, poor and voiceless China and consider the Chinese people as, at least, our equals.

[more ▼]Using our photometric observations taken between April 1996 and January 2013 and other published data, we derive properties of the binary near-Earth asteroid (175706) 1996 FG3 including new measurements constraining evolution of the mutual orbit with potential consequences for the entire binary asteroid population. We also refined previously determined values of parameters of both components, making 1996 FG3 one of the most well understood binary asteroid systems. We determined the orbital vector with a substantially greater accuracy than before and we also placed constraints on a stability of the orbit. Specifically, the ecliptic longitude and latitude of the orbital pole are 266{\deg} and -83{\deg}, respectively, with the mean radius of the uncertainty area of 4{\deg}, and the orbital period is 16.1508 +\- 0.0002 h (all uncertainties correspond to 3sigma). We looked for a quadratic drift of the mean anomaly of the satellite and obtained a value of 0.04 +\- 0.20 deg/yr^2, i.e., consistent with zero. The drift is substantially lower than predicted by the pure binary YORP (BYORP) theory of McMahon and Scheeres (McMahon, J., Scheeres, D. [2010]. Icarus 209, 494-509) and it is consistent with the theory of an equilibrium between BYORP and tidal torques for synchronous binary asteroids as proposed by Jacobson and Scheeres (Jacobson, S.A., Scheeres, D. [2011]. ApJ Letters, 736, L19). Based on the assumption of equilibrium, we derived a ratio of the quality factor and tidal Love number of Q/k = 2.4 x 10^5 uncertain by a factor of five. We also derived a product of the rigidity and quality factor of mu Q = 1.3 x 10^7 Pa using the theory that assumes an elastic response of the asteroid material to the tidal forces. This very low value indicates that the primary of 1996 FG3 is a 'rubble pile', and it also calls for a re-thinking of the tidal energy dissipation in close asteroid binary systems.

[more ▼]Nonlinear (systems of) ordinary differential equations (ODEs) are common tools in the analysis of complex one-dimensional dynamic systems. In this paper we propose a smoothing approach regularized by a quasilinearized ODE-based penalty in order to approximate the state functions and estimate the parameters defining nonlinear differential systems from noisy data. Within the quasilinearized spline based framework, the estimation process reduces to a conditionally linear problem for the optimization of the spline coefficients. Furthermore, standard ODE compliance parameter(s) selection criteria are easily applicable and conditions on the state function(s) can be eventually imposed using soft or hard constraints. The approach is illustrated on real and simulated data.

[more ▼]Recent results from the Kepler mission indicate that super-Earths (planets with masses between 1-10 times that of the Earth) are the most common kind of planet around nearby Sun-like stars. These planets have no direct solar system analogue, and are currently one of the least well-understood classes of extrasolar planets. Many super-Earths have average densities that are consistent with a broad range of bulk compositions, including both water-dominated worlds and rocky planets covered by a thick hydrogen and helium atmosphere. Measurements of the transmission spectra of these planets offer the opportunity to resolve this degeneracy by directly constraining the scale heights and corresponding mean molecular weights of their atmospheres. We present Hubble Space Telescope near-infrared spectroscopy of two transits of the newly discovered transiting super-Earth HD 97658b. We use the Wide Field Camera 3's scanning mode to measure the wavelength-dependent transit depth in thirty individual bandpasses. Our averaged differential transmission spectrum has a median 1 sigma uncertainty of 19 ppm in individual bins, making this the most precise observation of an exoplanetary transmission spectrum obtained with WFC3 to date. Our data are inconsistent with a cloud-free solar metallicity atmosphere at the 17 sigma level. They are a good match for flat models corresponding to either a metal-rich atmosphere or a solar metallicity atmosphere with a cloud or haze layer located at pressures of a mbar or higher.

As intermediate-mass planets in short orbits around aged, cool stars ($7^{+2}_{-1}$Gyr for WASP-20 and$5^{+3}_{-2}$Gyr for WASP-28; both with$T_{\rm eff}< 6250 K), their orbital alignment is consistent with the hypothesis that close-in giant planets are scattered into eccentric orbits with random alignments, which are then circularised and aligned with their stars' spins via tidal dissipation.

[more ▼]Discrete ordinal responses such as Likert scales are regularly proposed in questionnaires and used as dependent variable in modeling. The response distribution for such scales is always discrete, with bounded support and often skewed. In addition, one particular level of the scale is frequently inflated as it cumulates respondents who invari- ably choose that particular level (typically the middle or one extreme of the scale) without hesitation with those who chose that alternative but might have selected a neighboring one. The inflated discrete beta regression (IDBR) model addresses those four critical characteristics that have never been taken into account simultaneously by existing models. The mean and the dispersion of rates are jointly regressed on covariates using an underlying beta distribution. The probability that choosers of the inflated level invariably make that choice is also regressed on covariates. Simulation studies used to evaluate the statistical properties of the IDBR model suggest that it produces more precise predictions than competing models. The ability to jointly model the location and dispersion of (the distribution of) an ordinal response, as well as to characterize the profile of subject selecting an ”inflated” alternative are the most relevant features of the IDBR model. It is illustrated with the analysis of the political positioning on a ”left-right” scale of the Belgian respondents in the 2012 European Social Survey.

[more ▼]Whereas a centralized model of electricity infrastructure is still dominant today, many scholars advocate the diffusion of distributed generation technologies, implying geographically dispersed and small-scale generation units located close to consumers. However, there exist various barriers of different natures to a large-scale penetration of these technologies. In this article, we focus on the behavioral and psychological ones, emphasizing the roles that citizens have to play in this issue. More specifically, we explore a specific way of involving citizens in such diffusion, namely energy cooperatives. After presenting the driving forces of the emergence of cooperative firms in the energy sector, we examine the assets of the cooperative ownership structure from the perspectives of behavioral economics and social psychology. Our analysis enables us to build a model of how cooperatives may enhance consumer engagement in the diffusion of distributed generation technologies. This provides a basic theoretical framework for future empirical research.

[more ▼]Whereas a centralized energy supply system is still dominant today, the energy sector is currently witnessing the development of small-scale and more geographically dispersed generation units, so-called distributed generation technologies. So-called "alignment framework" proposes a very useful approach to look at this evolution. Yet, we argue in this paper that this framework does not fully take into account the inertia associated with past technological and institutional choices that may hinder future changes. Relying on the concept of socio-technical lock-in, we illustrate this point with the case of the diffusion of distributed generation technologies. Based on this analysis, we propose an adaptation of the alignment framework to integrate these elements.

[more ▼]This paper investigates whether physicians induce demand for C-sections in the days preceding leisure periods. I reject that doctors are meaningfully increasing the number of primary cesareans to accommodate their own preferences for control of deliveries around holiday Mondays. Using a sample of more than 1,300,000 deliveries, I can estimate that the induced demand due to convenience is close to zero. A small signi cant e ect is found for women having had a previous C-section. While I replicate previous results of lower C-section rates on leisure periods, I show that they are due to the way doctors schedule planned cesareans rather than to an induced demand for reason of physicians' convenience. If induced demand occurs, the decision takes place in the labor room and is not planned in advance. [less ▲]Detailed reference viewed: 10 (2 ULg) Des royaumes aux nations ?

The starting point is a spline approximation to the generator of an Archimedean copula.

The performances and properties of the spline estimate of the reference generator and the abilities of these conditional models to approximate conditional copulas are studied through simulations. Inference is made using Bayesian arguments with posterior distributions explored using im- portance sampling or adaptive MCMC algorithms. The modelling strategy is illustrated with two examples.

WASP-69b is a bloated Saturn-mass planet (0.26 M$_{\rm Jup}$, 1.06 R$_{\rm Jup}$) in a 3.868-d period around an active mid-K dwarf. We estimate a stellar age of 1 Gyr from both gyrochronological and age-activity relations, though an alternative gyrochronological relation suggests an age of 3 Gyr. ROSAT detected X-rays at a distance of 60$\pm$27 arcsec from WASP-69. If the star is the source then the planet could be undergoing mass-loss at a rate of ~10$^{12}$ g s$^{-1}$. This is 1-2 orders of magnitude higher than the evaporation rate estimated for HD 209458b and HD 189733b, both of which have exhibited anomalously-large Lyman-{\alpha} absorption during transit. WASP-70Ab is a sub-Jupiter-mass planet (0.59 M$_{\rm Jup}$, 1.16R$_{\rm Jup}$) in a 3.713-d orbit around the primary of a spatially-resolved G4+K3 binary, with a separation of 3.3 arcsec ($\geq$800 AU). We exploit the binary nature of the system to construct a H-R diagram, from which we estimate its age to be 9-10 Gyr. WASP-84b is a sub-Jupiter-mass planet (0.69 M$_{\rm Jup}$, 0.94 R$_{\rm Jup}$) in an 8.523-d orbit around an active early-K dwarf. Of the transiting planets discovered from the ground to date, WASP-84b has the third-longest period. From a combination of gyrochronological and age-activity relations we estimate the age of WASP-84 to be ~1 Gyr. For both the active stars WASP-69 and WASP-84 we find a modulation of the radial velocities with a period similar to the photometrically-determined stellar rotation period.

[more ▼]We propose to use Kepler in 2-wheel mode to conduct a detailed search for Earth-sized planets orbiting ultra-cool stars and brown dwarfs (spectral types from M7 to L3). This population of objects presents several advantages for exoplanet surveys. First, ultra-cool stars and brown dwarfs are small and thus result in favorable planet-to-star area ratios. Second, because of their low effective temperature, the inner edge of their habitable zone is extremely close (2 to 3 days only). Third, our targets are bright at infrared wavelengths, which will enable detailed follow-up studies. Our program therefore represents a unique opportunity to find a transiting Earth-size exoplanet for which atmospheric features (including biosignatures) could be detected with near-to-come facilities such as JWST. Such exoplanet has not been discovered yet. Kepler in 2-wheel mode provides the required stability and photometric precision to make this survey successful. Our initial target sample includes 60 ultra-cool stars and brown dwarfs from which we expect to detect at least one transiting planet. We propose to monitor each source for 4 days, resulting in a total program duration of ~240 days.

[more ▼]This paper investigates whether physicians induce demand for C-sections in the days preceding leisure periods. I reject that doctors are meaningfully increasing the number of cesareans to accommodate their own preferences for control of deliveries around holiday Mondays. Using a sample of more than 1,300,000 deliveries, I can precisely estimate that the induced demand due to convenience is close to zero. While I replicate previous results of lower C-section rates on leisure periods, I show that they are due to the way doctors schedule planned cesareans rather than to an induced demand for reason of physicians' convenience.

[more ▼]If governance has become, for many years, as a matter of paramount importance in traditional companies (Berle & Means, 1932), microfinance institutions have also not escaped this need (Rock et al. 1998), there are about thirty years. Considered essential to address issues related to economic and social development (Wélé, 2009), governance is also emerging as an undeniable factor for to strengthen the financial performance and to increase awareness in microfinance institutions (Rock et al., 1998; Labie, 2001 Helms, 2006). Several authors have contributed to the understanding of corporate governance by using a variety of theoretical approaches (Jensen & Meckling (1976), Fama and Jensen (1983a) for Shareholders approach, Freeman (1984), Donaldson & Preston (1995) Hung (1998) for the stakeholder approach, Meyer and Rowan (1977), Mertens (2010), Muth & Donaldson (1998), Berle & Means (1932); Labie (2005a) for alternative approaches). Applied individually in cooperatives and organizations, these approaches have proved rather one-dimensional and illuminate one aspect of the Boards of Directors (Cornforth, 2004). Hence the need for an approach that integrates the insights of these perspectives has been felt. Thus, a perspective in terms of paradox (Cornforth, 2004) helped to highlight the dilemmas, paradoxes and tensions that boards of directors are facing. Several researchers have used this paradox perspective in different organizations (Demb & Neubauer, 1992 Wood, 1996; Sundaramurthy & Lewis, 2003), but it also did not take long. Criticized for focusing only on the board, this perspective paradox is also alleged to ignore the role of contextual factors. However, as argued by DiMaggio & Powell (1983), Meyer and Rowan (1977), environmental factors play an undeniable role in the way organizations make isomorphic. Rijpens & Adam (2011) also point out that the internal and external factors to the organization involved in the debate on the governance model adopted. Hudon and Seibel (2007) argue that conflicts and disasters seriously affect the socio-economic institutions, public governance, networks and social relations of citizens, including those related to the exchange or transfer of financial resources. This article examines the influence of armed conflict on the cooperatives’ governance. It is built around three fundamental questions. (1) What overlay the systems of cooperatives governance? (2) What is the theoretical model of governance adapted to cooperatives working in conflict situations? (3) How an armed conflict does it influence the cooperatives governance? To answer these questions, this article assumes, first, the confrontation of existing theoretical approaches in the literature on corporate governance in general and cooperatives in particular. It then develops a model of governance adapted to the conflict. Finally, that model will be tested after data collect from a qualitative field study based on the triangulation of information resources and interviews with key players in organizations under study in a country where microfinance institutions have evolved conflict situations. The results will be presented in another article.

Investigations ... [more ▼]Several studies on the sources of funding for local NGOs in Africa highlight their dependence on foreign donors, while in developed countries, these organizations have multiple resources. Investigations previously done show that the majority of resources of local NGOs come from foreign donors, and most of them are dead at inception due to lack of funding. Before reaching the beneficiaries, financing goes through several players who are related by an explicit contract: Foreign donors - International NGOs - Local NGOs - Endogenous groups - beneficiaries populations. The literature points to the existence of a contractual relationship between the one who runs the activities and the one that funds them. Yet despite this explicit contract, some actors in this chain of relationships are influenced by other factors and / or their interests and make decisions that have no direct links with the mission of the organization. This leads us to ask ourselves two questions: first, the question about the factors that characterize the relationship between actors and secondly whether at all levels, the actors involve other stakeholders. The present paper aims to provide a conceptual and theoretical framework to characterize the agency chain relationship between these different actors. Although there are studies on the application of the agency theory in the governance of Nonprofit organizations, there have been very few studies done on the agency chain relationship between these organizations. It is then necessary to make new theoretical developments on how local NGOs in Africa in general, and Burundi in particular, are funded and governed; and that, in the case where the actors in the chain relationship are in different contexts. To do this, we will first mobilize and apply the agence theory and others theories of governance at this agency chain relationship. We conclude by showing the peculiarity of Africa in general, and Burundi in particular with additional elements that enhance this agency relationship, making then the conceptual model complex.

However, market prices of both products do not appear to be different. This paper addresses this puzzle. First, I confirm the preference for local products. Using choice-based-conjoint data, I evaluate that Senegalese consumers are willing to pay a positive and significant premium for these products. Then, I identify the determinants of prices, based on a unique dataset of milk products characteristics. Evidence suggests that consumers' misinformation regarding the product composition prevents them from allocating a higher price to local milk-based products.

[more ▼]IT organization design, consisting of IT governance (decision rights) and IT organization structure, is believed to affect organizational performance. This paper describes the IT organization design choices of the 50 U.S. state governments. Significant movement toward greater centralization was observed (particularly for IT services). States appeared to have adopted IT organization design innovations previously pioneered in the private sector, contrary to conventional wisdom founded on well-documented differences between the two sectors. Two commonly used explanations of IT organization design choices were examined for their ability to account for the unexpected findings — contingency and institutional theories. Both explanations were partially successful in explaining the results, but further theoretical development is needed to integrate those theories and more empirical research is needed to advance the field’s knowledge of IT organization design.

[more ▼]The meter-per-second precision achieved by today velocimeters enables the search for 1-10 M_Earth planets in the habitable zone of cool stars. This paper reports on the detection of 3 planets orbiting GJ163 (HIP19394), a M3 dwarf monitored by our ESO/HARPS search for planets. We made use of the HARPS spectrograph to collect 150 radial velocities of GJ163 over a period of 8 years. We searched the RV time series for coherent signals and found 5 distinct periodic variabilities. We investigated the stellar activity and casted doubts on the planetary interpretation for 2 signals. Before more data can be acquired we concluded that at least 3 planets are orbiting GJ163. They have orbital periods of P_b=8.632+-0.002, P_c=25.63+-0.03 and P_d=604+-8 days and minimum masses msini = 10.6+-0.6, 6.8+-0.9, and 29+-3 M_Earth, respectively. We hold our interpretations for the 2 additional signals with periods P_(e)=19.4 and P_(f)=108 days. The inner pair presents an orbital period ratio of 2.97, but a dynamical analysis of the system shows that it lays outside the 3:1 mean motion resonance. GJ163c, in particular, is a super-Earth with an equilibrium temperature of T_eq = (302+-10) (1-A)^(1/4) K and may lie in the so called habitable zone for albedo values (A=0.34-0.89) moderately higher than that of Earth (A_Earth=0.2-0.3).

We report here about the use but more particularly the algorithms, the equations and the data sets of three software belonging to the Gabriel package. The first one, Gabriel Nathalie II, is a calculator with many functionality's. It is possible to calculate the pKa or to simulate the chemical shift in 31P NMR of amino-phosphonate. Moreover it is also able to dertimine the thermodynamics data of bisphosphonate binding to human bones. The second one, Gabriel Calculatrice Savon, is used to calculate the amount of alkali needed for making a soap according to the amount and the nature of fat but also the viscosity of some oils at a desired temperature. And at least Gabriel Data Analysis is a software devoted to data analysis. Today, software for research can be used for educational and educational software can be useful for research.

[more ▼]It is generally thought that galaxies are embedded in dark matter halos extending well beyond their luminous matter. The existence of these galactic halos is mainly derived from the larger than expected velocities of stars and gas in the outskirts of spiral galaxies. Much less is known about dark matter around early-type (elliptical or lenticular) galaxies. We use gravitational lensing to derive the masses of early-type galaxies deflecting light of background quasars. This provides a robust measurement of the total mass within the Einstein ring, a circle whose diameter is comparable to the separation of the different quasar images. We find that the mass-to-light ratio of the lensing galaxies does not depend on radius, from inner galactic regions out to several half-light radii. Moreover, its value does not exceed the value predicted by stellar population models by more than a factor two, which may be explained by baryonic dark matter alone, without any need for exotic matter. Our results thus suggest that, if dark matter is present in early-type galaxies, its amount does not exceed the amount of luminous matter and its density follows that of luminous matter, in sharp contrast to what is found from rotation curves of spiral galaxies.

[more ▼]There is strong scientific interest in Ganymede (Jupiter's third Galilean moon) and its surrounding environment, which stems from the likely presence of a liquid water ocean underneath its icy crust and from its internally driven magnetic field. The interaction of the latter with Jupiter's magnetospheric plasma and its magnetic field gives rise to a unique situation in our solar system implying a mini-magnetosphere embedded within a giant-magnetosphere. This interaction generates Ganymede's ultraviolet auroral footprint in Jupiter's atmosphere. We propose to investigate the strong auroral connection between Jupiter and Ganymede and the variable characteristics of Ganymede's magnetosphere with an innovative approach, taking advantage of the large scale north-south asymmetries of Jupiter's magnetic field. The results obtained for Ganymede will be compared with the case of small injected hot plasma bubbles observed by the Galileo spacecraft and whose size and location are similar to those of Ganymede's magnetosphere. HST is currently the sole instrument capable of obtaining this information which pins down the proposed mechanisms linking the source and sink regions of auroral particles in the giant planets' magnetospheres.

[more ▼]The paper proposes an equilibrium asset pricing model that accounts of the incomplete information on returns distribution and investors' preferences. Only moments up to order four of unknown unconditional distribution can be observed, and the model does not impose that portfolio diversi fication or moments preference should hold. Using Chebyshev-type of inequalities, an intuitive risk measure (risk horizon) is introduced with reference to the speed of convergence of a security's mean return to its expectations. By an arbitrage argument, this risk measure is related to the horizon of treasury securities in a system of equations that allows the calibration of the model parameters using term structure information. In particular, the expected return on the market portfolio can be endogenously estimated inside this system. The model calibration on U.S. market data provides plausible parameters estimates and interesting cyclical patterns in the time series of the expected return. The empirical relevance of these estimates is examined with tests of statistical and economic predictive ability for stock excess returns. The results provide signi ficant evidence on the added value of the estimates when compared to popular predictors found in the literature (see a.o. Lettau and Ludvigson, 2001; Rapach and Wohar, 2006; Goyal and Welch, 2008).

[more ▼]Il sera ici question de phénomènes réflexifs qui, au sein d’un texte littéraire, produisent des écarts sensibles et rompent le processus classique de la représentation du réel. Les cas rencontrés sont étonnamment divers, tant en ce qui concerne leur structure que les effets produits. C’est pourquoi l’on se propose de les classer en six catégories distinctes : réflexivité autotélique, réflexivité poétique, réflexivité linguistique, réflexivité de l’énonciateur, réflexivité conative et réflexivité référentielle.

[more ▼]This paper discusses challenges for competition authorities in the 21st century. Those challenges were identified on the basis of a statistical review of the articles published since January 2011 in five major antitrust law journals. The assumption underlying this literature review is that the topics that statistically attract the most the attention from contemporary antitrust scholars are those that will likely constitute the main challenges for 21st century competition authorities.

This paper develops the ... [more ▼]The success of e-government is believed to depend in part on the organizational and institutional arrangements that governments enact for the management of their IT resources. This paper develops the conceptualization of IT management arrangements by considering possible interactions between two dimensions — 1) the organization of IT activities and 2) control over decisions about IT activities (also known as governance) — for each of two categories of IT activities — 1) IT projects (such as website development) and 2) IT services (such as the operation of networks). In addition, the paper provides preliminary empirical evidence obtained from applying this expanded conceptualization in the context of American state governments. Many states appear to employ centralization of IT activities to offset decentralization of IT control and vice versa. Consequently, neither dimension alone provides a good characterization of governmental IT management arrangements. These findings have the potential to enhance our understanding of the barriers to, and enablers of, e-government success.
