Dual licensing strategy with open source competition
Auteurs : Torre Dominique,Eric Darmon
Revue : Managerial and Decision Economics
Éditeur : Wiley
Année : 2016

Software firms that produce and sell proprietary software can use dual licensing (DL) strategies\,that is\, they can distribute their products under different (proprietary\, OS\, e.g.\, open source)licensing terms. We investigate the relevance and impacts of such distribution strategies in thepresence of an OS software competitor. We determine the conditions for this strategy to be profitablefor the software firm\, and its impact on price\, market share\, and welfare. We show that aDL strategy can be used to crowd the OS software out of the market. This strategy then is profitablefor the software firm only if the spillovers coming from the hybrid software (i.e.\, second distributionlaunched by the software firm) are sufficiently high and result in both a higher price anda lower market share for the proprietary software. We also consider a situation where the introductionof DL leads to a market shared between the firm's software and the OS competitor. Inthis situation\, the profitability of the DL strategy depends also on the degree of compatibilitybetween the proprietary software and its OS competitor. We show also that this situation cangenerate conflicts of interests between proprietary software vendors and users\, resulting in suboptimaloutcomes.

Shanshan Lan is an Associate Professor in the Department of Anthropology at the University of Amsterdam. She has been conducting researches for nearly twenty years on Chinese migration to the United States\, on Africans in the Chinese metropolis of Guangzhou and on whiteness in China. In the following interview\, Shanshan Lan introduces her biographical and scholarly background\, her training as an anthropologist in the United States and her distanced use of Western social sciences. She also discusses several concepts that she has developed from empirical investigations: “racial knowledge”\, “overlapping racialization”\, “grassroots interracial interaction”\, and the difference she makes between “white privilege” and “white skin privilege”.

Effects of different ways of incentivizing price forecasts on market dynamics and individual decisions in asset market experiments
Auteurs : Nobuyuki Hanaki,Eizo Akiyama,Ryuichiro Ishikawa
Revue : Journal of Economic Dynamics and Control
Éditeur : Elsevier
Année : 2018

In this study\, we investigate (a) whether eliciting future price forecasts influences market outcomes and (b) whether differences in the way in which subjects are incentivized to submit " accurate " price forecasts influence market outcomes as well as the forecasts in an experimental asset market. We consider four treatments: one without forecast elicitation and three with forecast elicitation. In two of the treatments with forecast elicitation\, subjects are paid based on their performance in both forecasting and trading\, while in the other treatment with forecast elicitations\, they are paid based on only one of those factors\, which is chosen randomly at the end of the experiment. We found no significant effect of forecast elicitation on market outcomes in the latter case. Thus\, to avoid influencing the behavior of subjects and market outcomes by eliciting price forecasts\, paying subjects based on either forecasting or trading performance chosen randomly at the end of the experiment is better than paying them based on both. In addition\, we consider forecast-only experiments: one in which subjects are rewarded based on the number of accurate forecasts and the other in which they are rewarded based on a quadratic scoring rule. We found no significant difference in terms of forecasting performance between the two.
Gender and the Publication Output of Graduate Students: A Case Study

Année : 2016

We examine gender differences among the six PhD student cohorts 2004–2009 at the California Institute of Technology using a new dataset that includes information on trainees and their advisors and enables us to construct detailed measures of teams at the advisor level. We focus on the relationship between graduate student publications and: (1) their gender; (2) the gender of the advisor\, (3) the gender pairing between the advisor and the student and (4) the gender composition of the team. We find that female graduate students co-author on average 8.5% fewer papers than men; that students writing with female advisors publish 7.7% more. Of particular note is that gender pairing matters: male students working with female advisors publish 10.0% more than male students working with male advisors; women students working with male advisors publish 8.5% less. There is no difference between the publishing patterns of male students working with male advisors and female students working with female advisors. The results persist and are magnified when we focus on the quality of the published articles\, as measured by average Impact Factor\, instead of number of articles. We find no evidence that the number of publications relates to the gender composition of the team. Although the gender effects are reasonably modest\, past research on processes of positive feedback and cumulative advantage suggest that the difference will grow\, not shrink\, over the careers of these recent cohorts.
Harvesting cereals at Dja’de el-Mughara in the northern Levant: New results through microtexture analysis of Early PPNB sickle gloss (11th millennium cal BP)

The origin of cereal domestication is a key current issue of archaeological research in the Fertile Crescent. Archaeobotanical evidence highlights a complex scenario for when and where agricultural practices started. Gloss texture analysis of sickle blades with confocal microscopy represents a new contribution to the knowledge of this process. A previous study (Ib´a˜nez et al.\, 2016) pointed to the Middle Euphrates in the Levant as one region where cereal cultivation occurred since the 13th millennium cal BP and progression towards cereal domestication was since then continuous\, culminating in the mid-10th millennium cal BP\, in the Middle PPNB. However\, the transition from the Early to the Middle PPNB – between 10\,200 9\,800 cal BP –\, a key period previous to the appearance of the first domestic cereals\, is not fully understood. This paper presents the quantitative analysis of gloss microtexture on 48 sickles blades from the Early PPNB levels of Dja’de el-Mughara (c. 10\,650–10\,350 cal BP)\, where pre-domestic cultivation of wild cereals is attested by archaeobotanical studies. Gloss texture analysis of sickle blades indicates that though reaping semi-ripe cereals associated to cutting wild cultivated cereals is dominant\, other group of tools reaped cereals in an advanced degree of maturity. Tools used for cutting green cereals are also present\, suggesting that wild cereals in natural stands were also exploited. This study exhibits the complexity of the cereal harvesting strategies at this transitional period\, suggesting the exploitation of cereal populations that were in different phases of the domestication process. The results were then compared with the previous research about 50 sickle elements from several sites from the Late Natufian (13th millennium cal BP) to the Late PPNB (late 10th millennium cal BP) in the Middle Euphrates.
L’Unesco\, à l’origine de l’antiracisme ? Ethnographie historique de la question raciale (1946-1952)
Auteurs : Elisabeth Cunin
Revue : Critique Internationale
Éditeur : Presses de Sciences Po
Année : 2020

L’Unesco est considérée comme un des principaux acteurs de l’antiracisme international qui émerge au lendemain de la seconde guerre mondiale. Pourtant\, la « question raciale » n’est pas une priorité de l’institution au tournant des années 1940-1950 et celle-ci n’a jamais été en mesure de définir et de mettre en oeuvre une politique claire et explicite sur le sujet. Une ethnographie historique des archives de l’Unesco à Paris\, notamment au moment de la création et des premières réunions du Département des sciences sociales\, révèle que ce dernier accueille les discussions sur la question raciale de façon souvent contrainte et improvisée. Loin du récit linéaire des origines de l’antiracisme\, il convient donc d’insister plutôt sur l’indétermination constitutive de l’élaboration des programmes sur la race à l’Unesco entre 1946 et 1952.
Scrutinizing the Direct Rebound Effect for French Households using Quantile Regression and data from an Original Survey
Auteurs : Fateh Belaïd,Adel Ben Youssef,Nathalie Lazaric

Éditeur : Elsevier
Année : 2020

This article develops a quantile regression model to measure the magnitude of the direct rebound effect for residential electricity demand based on micro-level data from an original survey of a representative sample of 2356 French households. We explore the rebound effect for different groups of residents. Traditionally\, debate has focused on decreased prices for energy services due to efficiency improvements and their effects on energy demand. The methodological innovation provided by this paper is that it implements two theoretical estimation strategies: (i) energy efficiency elasticity of the demand for energy services\, and (ii) price elasticity of the demand for energy services. Our findings reject the hypothesis of a backfire effect in the context of residential electricity use. Specifically\, based on energy efficiency elasticity\, we provide evidence of a rebound effect of between 72% and 86% but with substantial heterogeneity among consumption quantiles. Our results show that the direct rebound effect has critical relevance for energy efficiency policy in the face of energy invisibility in France.

This study investigated associations between executive functions (i.e.\, inhibition\, working memory\, cognitive flexibility) and individual differences in self-control and health behaviors. We examined whether executive functions predict physical activity\, sedentary activity\, and healthy and unhealthy diets\, and whether trait self-control and self-control resources mediate these associations. Three hundred and eighty-five participants completed a questionnaire assessing trait self-control and self-control resources\, physical activity\, sedentary activity\, and healthy and unhealthy diets. They also performed three randomly ordered cognitive tasks\, a stop-signal task (i.e.\, inhibition)\, a letter memory task (i.e.\, updating)\, and a number-letter task (i.e.\, switching). Structural equation modeling revealed that self-control resources predicted positively physical activity (R2 = 0.08)\, negatively sedentary activity (R2 = 0.03) and positively healthy diet (R2 = 10). Moreover\, trait self-control predicted positively healthy diet (R2 = 0.10) and negatively unhealthy diet (R2 = 0.19). Moreover\, analyses revealed that switching significantly predicted self-control resources\, and highlighted three totally mediated relations between this executive function and physical activity\, sedentary activity and healthy diet. However\, no evidence was found supporting associations between inhibition and updating\, and health behaviors\, or relations mediated by self-control for these executive functions. The findings suggest the importance of trait self-control and self-control resources for health behavior adoption and pave the way for studies exploring the role of the executive functions in an affective context.

Modeling structural change in the European metropolitan areas during the process of economic integration
Auteurs : Christian Longhi,Antonio Musolesi,Catherine Baumont
Revue : Economic Modelling
Éditeur : Elsevier
Année : 2014

The specialization patterns ofmetropolitan areas are crucial in characterizing the effects of economic integration in Europe. This paper aims to provide and estimate an econometricmodel that explains both sectoral specialization and sectoral dissimilarity\,measuredwith the GINI and the KRUGMAN indexes\, respectively\, for 35 European metro areas during the period 1980–2005. A semiparametric approach is proposed to address the issues of nonlinearity and separability. The econometric analysis indicates how the deepening of the processes of development and integration occurred in the last decades affected both specialization and similarity of the sectoral metropolitan structure\, finally supporting a “specializing alike hypothesis”

Disguising Exploitation. Immigrants in the Ecuadorian Gig Economy
Auteurs : María Belén Albornoz,Henry Chavez
Revue : Trilogía Ciencia Tecnología Sociedad
Année : 2023

Ecuador is home to approximately 556\,000 immigrants\, mostly from Venezuela (65%) and Colombia (25%)\, many of whom have an irregular immigration status. In Ecuador\, an immigrant without a visa cannot work\, which creates a scenario that favours abuse by employers and hinders immigrants’ ability to organize and negotiate their rights. Part of this population has found the platform economy to be a flexible way to find work and earn an income quickly. However\, this has also given rise to new forms of exploitation. The objective of this article is to analyse the relationship between the development of the platform economy in Ecuador and the labour conditions of the migrant population that has entered the country in recent years. We used a qualitative methodology based on direct observation\, semi-structured interviews (46) and in-depth interviews (10). The main results of this research show that the development of the platform economy and the lack of adequate legislation have produced new forms of disguised exploitation\, particularly of immigrant workers. These new forms of exploitation operate through a black market of profile and vehicle subcontracting which\, in their interaction with the algorithmic management systems of these applications\, end up worsening the already precarious working conditions of the migrant population that uses these applications as a means of survival. The article concludes with a brief analysis of these working conditions in relation to the five principles of fair work.

This manuscript aims to develop a new multivariate composite index for monitoring agricultural drought. To achieve this\, the AVHRR\, VIIRS\, CHIRPS data series over a period of 40 years\, rainfall and crop yield data as references were used. Variables include parameters for vegetative stress (SVCI\, PV\, SMN)\, water stress (PCI\, RDI\, NRDI)\, and heat stress (SMT\, TCI\, STCI)\, and a new variable related to environmental conditions was calculated through a normalized rainfall efficiency index. Then\, random forest algorithm was used to determine the weights of each component of the model by considering interannual fluctuations in cereal yields as an impact variable. The multivariate composite model was compared to the VHI\, NVSWI and SPI-12 indices for validation. The results show a large spatiotemporal concordance between the MDCI and the validation indices with a maximum correlation of 0.95 with the VHI and a highly significant p value (< 2.2e-16). Validation of the MDCI model by SPI-12 shows a significantly higher statistically significant relationship than that observed between SPI and VHI and NVSWI. P value range from 3.531e-05 to 6.137e-06 with correlations that vary between 0.6 and 0.64 depending on the station. It is also highly correlated with the Palmer drought severity index (PDSI) and climatic water deficit index (CWDI)\, with R = 0.85 and p value < 5.8e-10 and R = 0.72 and p value < 1.9e-6\, respectively. Finally\, the study provides a new direction for multivariate modeling of agricultural drought that should be further explored under various agroclimatic conditions.
L’inceste dans les pays d’Afrique subsaharienne. Analyse sociojuridique d’un tabou

Année : 2023

L’inceste est une problématique universelle\, car il touche toutes les sociétés du monde. Mais cette universalité n’empêche pas que des spécificités émergent. Tel est notamment le cas dans les pays d’Afrique subsaharienne où ce fléau présente un relief particulier. Dans un premier temps\, l’étude met en lumière la réprobation quasi unanime de l’inceste dans cette partie de l’Afrique. Cette réprobation s’est d’abord manifestée en droit coutumier à travers l’interdit incestueux\, avant d’être codifiée ensuite dans les législations modernes. Dans un second temps\, l’analyse s’intéresse au traitement de l’inceste et révèle les goulots d’étranglement qui persistent tant au niveau pénal qu’institutionnel.

Le devoir de désobéissance

Année : 2022

Le devoir d'obéissance est un principe hiérarchique structurant de l'armée. Pour autant\, la période immédiatement postérieure à la seconde guerre mondiale va faire évoluer le droit. Le militaire est alors placé juridiquement dans une situation paradoxale car il existe désormais en droit positif autant un devoir d'obéissance\, règle de base fondamentale dans l'armée\, qu'un devoir de désobéissance\, dicté par un droit de conscience impérieux\, ou encore par des normes fondamentales de droit international en ce qu'elles imposent des considérations élémentaires d'humanité. Reste que ce devoir de désobéissance est difficile à mettre en œuvre. Dès lors\, celui-ci devrait pouvoir être complété par un utile droit d'alerte qui n'est qu'à l'état embryonnaire\, au moins dans l'armée.
