Many significant intellectual developments have taken place in 20th century European social theories. Notably the first Frankfurt School and Bourdieu’s work have successfully shown how workers, social actors, etc. are alienated or dominated by capitalist social structures. But according to Habermas, neither perspective successfully allows for the possibility that people could contribute to their own emancipation. The emergence of new forms of social resistance to domination such as those embodied by the Indignados, Anonymous, Femen, the practitioners of alternative economy, movements of unemployed people or illegals compels us to envisage the possibility for emancipation, but how? In this paper we explore opportunities for accounting for this by considering the work of a range of other European social theorists, more specifically Boltanski whose critical intent is embodied in his pragmatic sociology, and evident in his coining and use of the concept of the world. In addition we will consider Latour’s own pragmatic stance as we believe that despite his disinterest in new social movements, his work, informed by pure immanence, might offer potential solutions. But we would argue that even in these innovations there is either a persistent tendency to imagine emancipation primarily as a return to some ideal state or a lack of critical engagement with alienation. In response, we propose a materialist renewal, which will lead us to ponder on the political role of sociologists. [less ▲]

From Marx to Althusser, the materialist approach has tended to assume that individuals (that is, workers, proletarians and other social actors), unconsciously reproduce the social structures of capitalism which alienate them. It is assumed that individuals accept the conditions forced upon them and no longer seek to rebel against a world which substantially impoverishes their labour, their spirit and their creativity. In this paper, I will try to show that by dint of favouring almost exclusively Marx's concept of alienation, there is a considerable risk that materialist thought will adopt only a negative path. Whilst I acknowledge Marx’s significance to materialism, I wish to argue that his stance should be combined with that of the anarchist and libertarian French thinker Proudhon. Proudhon has succeeded in presenting a conception of the worker as more than just alienated. Workers can also cooperate and experience a reciprocity seemingly at odds with the character of capitalism. Under Proudhon’s influence materialism takes a positive turn, enabling us to avoid falling into the utopianism that the theory of social economy employs to critique capitalism – a utopianism that renders its critique even less effective than that of Marx.

This work presents, compares and discusses results obtained with two indirect methods for the cal culation of aerodynamic forces and pitching moment from 2D Particle Image Velocimetry (PIV) measurements. Both methodologies are based on formulations of the momentum balance: the integral Navier-Stokes equations and the “flux equation” proposed by Noca et al. (1999), which has been extended to the computation of moments. The indirect methods are applied to spatio-temporal data for different separated flows around a plate with a 16:1 chord-to-thickness ratio. Experimental data are obtained in a water channel for both a plate undergoing a large amplitude imposed pitching motion and a static plate at high angle of attack. In addition to PIV data, direct measurements of aerodynamic loads are carried out to assess the quality of the indirect calculations. It is found that indirect methods are able to compute the mean and the temporal evolution of the loads for two-dimensional flows with a reasonable accuracy. Nonetheless, both methodologies are noise sensitive and, the parameters impacting the computation should thus be chosen carefully. It is also shown that results can be improved through the use of Dynamic Mode Decomposition (DMD) as a pre-processing step. [less ▲]

Because PU coatings offer a compromise between aesthetic and performance expectations, unachievable with other types of industrial paints, they are currently recognized as the most appropriate option to coat sculptures intended for an outdoor setting. However, the PU class includes various systems, such as two package solvent-borne, two package water-borne, one package water-borne and fluoropolymer polyurethanes, which possess very different properties. 115 reference samples of PU coatings were investigated by means of Py-GC/MS, in order to outline the differences and the similarities existing, in terms of composition, between the major PU systems used for creating as well as for conserving modern painted outdoor sculptures. The Py- GC/MS study of an extended number of reference samples showed that the composition of equivalent PU systems strongly varies depending on the product line and the manufacturer. Furthermore the comparison of all the produced pyrograms allowed defining characteristic marker compounds helpful to discriminate specific PU paint systems. [less ▲]

Like acrylics and alkyds, polyurethanes (PUs) represent an important class of industrial paints adopted by 20th and 21st artists; primarily by those creating outdoor painted sculptures (OPS). Because PU coatings offer a compromise between aesthetic and performance expectations, unachievable with other types of paints, they are commonly recognized as the most appropriate option for painted artworks intended for an outdoor setting. However, the PU class includes various systems and subgroups possessing very different properties. Through the FTIR-ATR study of 137 PU coating references from the Getty Conservation Institute (GCI) reference collection, this paper outlines the differences and the similarities existing, in terms of the composition, of two package solvent-borne, two package water-borne, one package water-borne and fluoropolymer polyurethanes. The comparison of the obtained FTIR-ATR results allowed determining markers helpful to discriminate specific PU subgroups by means of ATR-FTIR spectroscopy. The goals of this paper are to provide to the conservation professionals a better understanding of the versatility and diversity of PU coatings and to facilitate the identification of the various types initially used by the artists.

Since the Food and Drug Administration (FDA) published a guidance based on the Process Analytical Technology (PAT) approach, real-time analyses during manufacturing processes are in real expansion. In this study, in-line Raman spectroscopic analyses were performed during a Hot-Melt Extrusion (HME) process to determine the Active Pharmaceutical Ingredient (API) content in real-time. The method was validated based on a univariate and a multivariate approach and the analytical performances of the obtained models were compared. Moreover, on one hand, in-line data were correlated with the real API concentration present in the sample quantified by a previously validated off-line confocal Raman microspectroscopic method. On the other hand, in-line data were also treated in function of the concentration based on the weighing of the components in the prepared mixture. The importance of developing quantitative methods based on the use of a reference method was thus highlighted. The method was validated according to the total error approach fixing the acceptance limits at ± 15% and the α risk at ± 5%. This method reaches the requirements of the European Pharmacopeia norms for the uniformity of content of single-dose preparations. The validation proves that future results will be in the acceptance limits with a previously defined probability. Finally, the in-line validated method was compared with the off-line one to demonstrate its ability to be used in routine analyses. [less ▲]

This study analyzes the vulnerability of agricultural cropping systems based on millet and sorghum and the adoption of new technologies in Sahelian and Sudano - Sahelian areas in Mali (West Africa). Semi-structured interviews (ISS) using questionnaires addressed to the chiefs of family farm (FAE) were used for the collection of data. The descriptive statistics and matrices were realized for the data analysis using the following softwares: EXCEL and SPSS20.The results of the surveys conducted in 2014 among 360 farms in Sahelian and Sudano-Sahelian areas, shows that agricultural producers are aware of the main factors affecting the productivity of their cropping system and food security of agricultural holdings. Rainfall variability, characterized by failure and irregularity of rains is the main constraint of cropping systems based on millet and sorghum as stated by 97% of surveyed producers, followed by soil poverty 81%, and the lack of agricultural equipment 47%. The impacts of these factors at the farms level are translated by a decrease in the crops yields and on the frequency of the shortages in foodstuffs which are observed by 98% of the farms every year and more than 50% every 3 years. To reduce vulnerabilities, practices and innovations were adopted by farms as strategies. The main concern fertilizer micro dosing technics, seed soaking, improved varieties, organic and mineral fertilization, soils and water management technics, mechanical sowing, and agro forestry were adopted as strategies.

In August of 2015, the International Society of Hypnosis and Confederation Francophone d’hypnose et Therapies Breves co-sponsored a 1-day meeting among hypnosis researchers, just before the International Congress of Hypnosis in Paris, France. One of the goals of the meeting was to discuss the state-of-the- science of hypnosis research from the purview of clinical and cognitive neuroscience. The purpose of this article is to summarize the key issues that were raised during the discussions, including the points of agreement and disagreement among the participants (all of whom are authors on this article). Here we first briefly summarize what we view as (i) the most important research findings and developments in the field during the past two decades and (ii) the most salient challenges facing contemporary hypnosis research. Next, we summarize our discussion concerning directions for future hypnosis research and collaborative endeavors that could expand upon recent advances, ad- dress emerging challenges, and facilitate a reemergence of hypnosis research as a vital field within cognitive and clinical neuroscience.

Porcine reproductive and respiratory syndrome (PRRS) is a devastating disease in the swine industry. Identification of host genetic factors that enable selection for improved performance during PRRS virus (PRRSV) infection would reduce the impact of this disease on animal welfare and production efficiency. We conducted genomewide association study (GWAS) analyses of data from 13 trials of approximately 200 commercial crossbred nursery-age piglets that were experimentally infected with 1 of 2 type 2 isolates of PRRSV (NVSL 97-7985 [NVSL] and KS2006-72109 [KS06]). Phenotypes analyzed were viral load (VL) in blood during the first 21 d after infection (dpi) and weight gain (WG) from 0 to 42 dpi. We accounted for the previously identified QTL in the region on SSC4 in our models to increase power to identify additional regions. Many regions identified by single-SNP analyses were not identified using Bayes-B, but both analyses identified the same regions on SSC3 and SSC5 to be associated with VL in the KS06 trials and on SSC6 in the NVSL trials ( < 5 x 10); for WG, regions on SSC5 and SSC17 were associated in the NVSL trials ( < 3 x 10). No regions were identified with either method for WG in the KS06 trials. Except for the region on SSC4, which was associated with VL for both isolates (but only with WG for NVSL), identified regions did not overlap between the 2 PRRSV isolate data sets, despite high estimates of the genetic correlation between isolates for traits based on these data. We also identified genomic regions whose associations with VL or WG interacted with either PRRSV isolate or with genotype at the SSC4 QTL. Gene ontology (GO) annotation terms for genes located near moderately associated SNP ( < 0.003) were enriched for multiple immunologically (VL) and metabolism- (WG) related GO terms. The biological relevance of these regions suggests that, although it may increase the number of false positives, the use of single-SNP analyses and a relaxed threshold also increased the identification of true positives. In conclusion, although only the SSC4 QTL was associated with response to both PRRSV isolates, genes near associated SNP were enriched for the same GO terms across PRRSV isolates, suggesting that host responses to these 2 isolates are affected by the actions of many genes that function together in similar biological processes.

The present study principally aims at determining to which extent prenatal exercise (before and during gestation) could affect the initiation (establishment) and the expression of psychomotor sensitization induced by a representative dose of cocaine in young female and male mice. More specifically, we will assess cocaine-induced acute psychomotor-activating effects, psychomotor sensitization developing over 9 daily sessions (daily peritoneal injections of cocaine or saline) and the long-term expression of the sensitized response (30 days after the last sensitizing injection) in C57BL/6J mice born from mothers housed with or without a running wheel before and during gestation. Based on literature and on our prior results, the mice born from exercised mothers are expected to show significantly reduced levels of cocaine responsiveness in comparison with the control mice (born from unexercised mothers).

Whereas performance‐based financing (PBF) is nowdeveloping fast in the health sector in low‐ and middle‐income countries and is presented an innovative approach—concomitantly, subject to a separate research stream—it sharesmany features of the “managing for results” (MfR) and performance‐based budgeting (PBB) currents that have existed for decades. In this paper, we first argue that PBF as currently developed in the health sector in low‐ and middle‐income countries shares many features and thus can be viewed as an avatar of MfR andmore precisely PBB. Secondly,we drawlessons fromthe literature on MfR and PBB so as to (1) better apprehend PBF conceptually and (2) avoid pitfalls and better design PBF schemes in practice. We argue that the lessons from the theoretical and empirical literature on MfR and PBB offer interesting insights to feed into a “theory of change” of PBF, enabling to analyse critical aspects and better design PBF schemes. Moreover, it is hoped that just like MfR processes have been demonstrated as having the potential to boost individual performance not only through links with financial incentives but also through acting on other sources of motivation, one can demonstrate more accurately by which mechanisms the various elements of the PBF package can help improve health sector results.
