Variations sur l'affect : pensée de l'affect autour d'Ingeborg Bachmann.

Si la littérature est rarement considérée comme une science, comme vraie, comme créatrice d’un savoir, toujours un peu à l’écart, avec ses fictions, et ce malgré un médium, le langage, commun à la philosophie et dont la qualité discursive correspond au mode d’expression de la pensée, malgré sa place acquise parmi les disciplines académiques, c’est parce que nous refusons de voir quel rôle vital joue l’affect dans la naissance et l’élaboration de la pensée. Le rejet de l’affect par la science est lui-même le produit de plusieurs affects — peur, orgueil — à partir desquels nous créons le concept de « pensée » qui nous convient le mieux, qui nous rassure le plus : rationalité, linéarité, objectivité. En réalité, cette dernière est chaotique et subjective et c’est seulement à travers son expression dans le langage qu’elle s’ordonne et acquiert une apparence d’objectivité. Mais le langage est lui-même le produit d’affects : nulle vérité infaillible ne sous-tend l’élaboration de nos langues, de leurs règles grammaticales et des sens de leurs mots. Ainsi la littérature, malgré (ou à cause de) la fiction, les fables, les inventions, parce qu’elle est création langagière, parce qu’elle remet toujours en question le langage est, en réalité, plus lucide que la raison. De plus, toujours aux prises avec l’image, elle connaît, d’une certaine façon, l’affect. Elle tente de le représenter, afin de frapper et d’ébranler la conscience du lecteur. C’est à travers elle que j’ai voulu élaborer non pas un savoir rationnel, mais un savoir sur l’affect, un savoir affectif. Pensée critique et affect sont en effet deux composantes essentielles de la création littéraire, ce qui apparaît particulièrement dans l’œuvre d’Ingeborg Bachmann, qui compte à la fois une thèse en philosophie sur Heidegger, des recueils de poésie, de nouvelles, des essais et un cycle romanesque inachevé, Todesarten. Je me suis penchée plus précisément sur certaines de ses nouvelles ainsi que sur son seul roman achevé, Malina, afin d’y étudier la représentation de l’affect chez certains personnages féminins qui, pour éviter de trop souffrir, construisent autour d’elles un mur de mensonges. J’ai également porté une grande attention aux théories de Bachmann sur la littérature, qu’elle énonce dans ses Leçons de Francfort, ce qui m’a permis, en considérant en même temps ses œuvres de fiction de même que celles de quelques autres écrivains, d’expliquer (de façon non exhaustive) certains rôles de l’affect à la fois chez l’écrivain et chez le lecteur.

How do social interactions with a significant other affect PTSD symptoms? An empirical investigation with a clinical sample.

Social support and coping are both related to posttraumatic stress disorder (PTSD) symptoms, but the mechanisms underlying their relationships remain unclear. This study explores these relationships by examining the perceived frequency of supportive and countersupportive interactions with a significant other in PTSD patients. Ninety-six participants with PTSD were recruited and completed questionnaires assessing social interactions, ways of coping, and PTSD symptoms. Associations of social interactions (r2 = 4.1%–7.9%, p < .05) and coping (r2 = 15.9%– 16.5%, p < .001) with symptoms were independent, and suggested a direct association between social interactions and PTSD. Countersupportive interactions were more associated to symptoms than supportive interactions. Our findings suggest the development of psychotherapies that integrate social support interventions.

La reconnaissance émotionnelle faciale : validation préliminaire de stimuli virtuels dynamiques et comparaison avec les Pictures of Facial Affect (POFA)

Bien que des photographies d’expressions émotionnelles faciales soient couramment utilisées pour étudier le traitement des informations affectives, les ensembles de stimuli actuels comportent différentes limites méthodologiques. Dans la perspective d’améliorer la validité écologique des travaux sur la reconnaissance émotionnelle faciale (REF), l’étude propose un nouvel ensemble de stimuli dynamiques constitué de personnages virtuels exprimant les six émotions fondamentales à différentes intensités. La validation préliminaire des stimuli a été effectuée en les comparant aux stimuli du POFA. Dans l’étude 1, le contenu émotionnel de 84 avatars statiques et de 48 photographies du POFA a été évalué par 150 étudiants. Dans l’étude 2, la REF a été évaluée chez 134 étudiants à l’aide d’avatars dynamiques. L’habileté à reconnaître les émotions est similaire à celle rapportée dans la littérature scientifique ainsi qu’au POFA. Les résultats permettent de conclure que les avatars constituent un ensemble valide de stimuli pour étudier la REF, offrant une contribution significative dans le domaine de la recherche émotionnelle. L’usage d’avatars étant de plus en plus courant à des fins d’intervention et de recherche, les stimuli ouvrent aussi la voie à diverses applications, entre autres pour l’étude des comportements violents. D’autres travaux devront être réalisés afin de poursuivre leur validation.

Do romantic partners' responses to entry dyspareunia affect women's experience of pain? : the roles of catastrophizing and self-efficacy.

Introduction Entry dyspareunia is a sexual health concern which affects about 21% of women in the general population. Characterized by pain provoked during vaginal penetration, introital dyspareunia has been shown by controlled studies to have a negative impact on the psychological well-being, sexual function, sexual satisfaction, and quality of life of afflicted women. Many cognitive and affective variables may influence the experience of pain and associated psychosexual problems. However, the role of the partner's cognitive responses has been studied very little. Aim The aim of the present study was to examine the associations between partners' catastrophizing and their perceptions of women's self-efficacy at managing pain on one side and women's pain intensity, sexual function, and sexual satisfaction on the other. Methods One hundred seventy-nine heterosexual couples (mean age for women = 31, SD = 10.0; mean age for men = 33, SD = 10.6) in which the woman suffered from entry dyspareunia participated in the study. Both partners completed quantitative measures. Women completed the Pain Catastrophizing Scale and the Painful Intercourse Self-Efficacy Scale. Men completed the significant-other versions of these measures. Main Outcome Measures Dependent measures were women's responses to (i) the Pain Numeric Visual Analog Scale; (ii) the Female Sexual Function Index; and (iii) the Global Measure of Sexual Satisfaction scale. Results Controlled for women's pain catastrophizing and self-efficacy, results indicate that higher levels of partner-perceived self-efficacy and lower levels of partner catastrophizing are associated with decreased pain intensity in women with entry dyspareunia, although only partner catastrophizing contributed unique variance. Partner-perceived self-efficacy and catastrophizing were not significantly associated with sexual function or satisfaction in women. Conclusions The findings suggest that partners' cognitive responses may influence the experience of entry dyspareunia for women, pointing toward the importance of considering the partner when treating this sexual health problem.

Cereal/legume rotations affect chemical properties and biological activities in two West African soils

A more widespread use of cereal/legume rotations has been suggested as a means to sustainably meet increasing food demands in sub-Saharan West Africa. Enhanced cereal yields following legumes have been attributed to chemical and biological factors such as higher levels of mineral nitrogen (Nmin) and arbuscular mycorrhizae (AM) but also to lower amounts of plant parasitic nematodes. This study was conducted under controlled conditions to examine the relative contribution of AM, plant parasitic nematodes and increased nitrogen (N) and phosphorus (P) availability to cereal/legume rotation effects on two West African soils. Sample soils were taken from field experiments at Gaya (Niger) and Fada (Burkina Faso) supporting continuous cereal and cereal/legume rotation systems and analysed for chemical and biological parameters. Average increases in cereal shoot dry matter (DM) of rotation cereals compared with continuous cereals were 490% at Gaya and 550% at Fada. Shoot P concentration of rotation millet was significantly higher than in continuous millet and P uptake in rotation cereals was on average 62.5-fold higher than in continuous cereals. Rotation rhizosphere soils also had higher pH at both sites. For the Fada soil, large increases in Bray1-P and organic P were observed in bulk and rhizosphere soils. Plant parasitic nematodes in roots of continuous cereals were 60–80-fold higher than in those of rotation cereals. In both cropping systems mycorrhizal infection rates were similar at 37 days after sowing (DAS) but at 57 DAS AM infection was 10–15% higher in rotation sorghum than in continuous sorghum. This study provides strong evidence that cereal/legume rotations can enhance P nutrition of cereals through improved soil chemical P availability and microbiologically increased P uptake.

Leguminous cover crops differentially affect maize yields in three contrasting soil types of Kakamega, Western Kenya

Maize production in smallholder farming systems in Kenya is largely limited by low soil fertility. As mineral fertilizer is expensive, green manuring using leguminous cover crops could be an alternative strategy for farmers to enhance farm productivity. However due to variability in soil type and crop management, the effects of green manure are likely to differ with farms. The objectives of this study were to evaluate Mucuna pruriens and Arachis pintoi on (i) biomass and nitrogen fixation (^15N natural abundance), (ii) soil carbon and nitrogen stocks and (iii) their effects on maize yields over two cropping seasons in Kakamega, Western Kenya. Mucuna at 6 weeks accumulated 1–1.3 Mg ha^{-1} of dry matter and 33–56 kg ha^{-1} nitrogen of which 70% was nitrogen derived from the atmosphere (Ndfa). Arachis after 12 months accumulated 2–2.7 Mg ha^{-1} of dry matter and 51–74 kg N ha^{-1} of which 52-63 % was from Ndfa. Soil carbon and nitrogen stocks at 0–15 cm depth were enhanced by 2-4 Mg C ha^{-1} and 0.3–1.0 Mg N ha^{-1} under Mucuna and Arachis fallow, irrespective of soil type. Maize yield increased by 0.5-2 Mg ha^{-1} in Mucuna and 0.5–3 Mg ha^{-1} in Arachis and the response was stronger on Nitisol than on Acrisol or Ferralsol. We concluded that leguminous cover crops seem promising in enhancing soil fertility and maize yields in Kenya, provided soil conditions and rainfall are suitable.

How do domestic policies affect the integration of Ethiopian fertiliser markets with world markets?

Frequent shifts in policy on fertiliser markets have occurred in Ethiopia with the aim of facilitating both physical and economic access of farmers to fertiliser. The last shift was the introduction of a monopoly on each stage of the supply chain in 2008. Furthermore, government control of prices and margins as well as stockholding programmes are also present on the markets. This paper evaluates the effect of these policies on the integration of domestic with world markets of fertiliser, using cointegration methods. Time series data of diammonium phosphate (DAP) and urea prices on world, import and retail markets between 1971 and 2012 are used. The findings show high transmission of price signals from world markets to import prices for both DAP and urea. However, between import and retail prices there is no evidence of cointegration for urea, while for DAP full price transmission is concluded. In the retail market, domestic transaction costs associated with storing large volumes of fertiliser act as a buffer between import and retail prices, especially for urea. Therefore, economic benefits could be achieved by reducing the size of stocks and revising the demand estimation process.

How neuroscience and sensorial theories can affect the marketing of different companies’ products and services?

El vertiginoso y competitivo panorama actual de los negocios, hace del mercadeo una herramienta muy importante para crecer o incluso sobrevivir. Hay muchas teorías alrededor de como vender un producto, servicio o idea, sin embargo la mayoría de estas consideran sólo las preferencias expresadas de forma consciente y las decisiones racionales. Este trabajo pretende hacer un acercamiento a las teorías de la neurociencia, como la sinergía entre los sentidos del ser humano y de como estas pueden nutrir el ámbito del mercadeo, por ello, se van a estudiar bibliografía relevante en torno a esta área para enmarcar el propósito del estudio. Después de la información obtenida a través de esta revisión, se analizaran dos importantes ejemplos de empresas mundialmente conocidas que han hecho uso de la neurociencia para el desarrollo de su mercadeo. Después de esto se concluye, a través de la información estudiada y analizada, cómo la neurociencia y las teorías multisensoriales pueden afectar el mercadeo de los diferentes productos y servicios. Este documento pretende vislumbrar efectos del mercadeo sobre las preferencias que nuestros cerebros muestran a través de la neurociencia, incluso si no sabemos sobre ellas.

Does the unemployment benefit institution affect the productivity of workers? evidence from a field experiment

We investigate whether and how the type of unemployment benefit institution affects productivity. We designed a field experiment to compare workers’ productivity under a welfare system, where the unemployed receive an unconditional monetary transfer, with their productivity under a workfare system, where the transfer is received conditional on the unemployed spending some time on ancillary activities. First, we find that having an unemployment benefit institution, regardless of whether it makes transfers conditional or unconditional, increases workers’ productivity. Second, we find that productivity is higher under Welfare than under Workfare. Becoming unemployed under Welfare comes at the psychological cost of a drop in self-esteem, presumably due to the shame or stigma associated with receiving an unconditional unemployment benefit. We document the empirical relevance of precisely this channel. The differences we observe in productivity suggest that this psychological cost acts as an extra nonmonetary incentive for workers under Welfare to put a higher effort in their work.

How do inequality affect tax morale in Latin America and Caribbean?

Latin America is well known as an inequitable region. As it is recognized, inequality and corruption perception weaken the way that political institutions works and the democratic system. Focusing on Latin American and Caribbean countries, this paper analyzes what are the elements shaping tax morale. In particular, how the context influences ethical grounds decisions such as the predisposition to pay taxes is analyzed, using the survey carried out in 2005 by Latinobarometro. The objective is to analyze how country performance determines tax morale. To do so, four probitmodels are estimated using Gini index, Transparency International Corruption Perception Index and Gross Domestic Product per capita (GDPpc) as explanatory variables. As expected we found that some socio-demographic variables play a relevant role. Interestingly, we also found that, in this attitude, LAC countries do not register a gender bias. However, those are not our main contributions to the literature on the field. The most important results are linked to: 1) the levelmatters, GDPpc increases the probability of people having tax morale, 2) moreover, income distributionalso influence on tax morale but in opposite direction and 3) corruption perception also reduces tax morale. Those results show that the quality of institutions matters and therefore, the way that democracy works play a relevant role.

Can salvage logging affect seed dispersal by birds into burned forests?

The recovery of vegetation in Mediterranean ecosystems after wildfire is mostly a result of direct regeneration, since the same species existing before the fire regenerate on-site by seeding or resprouting. However, the possibility of plant colonization by dispersal of seeds from unburned areas remains poorly studied. We addressed the role of the frugivorous, bird-dependent seed dispersal (seed rain) of fleshy-fruited plants in a burned and managed forest in the second winter after a fire, before on-site fruit production had begun. We also assessed the effect on seed rain of different microhabitats resulting from salvage logging (erosion barriers, standing snags, open areas), as well as the microhabitats of unlogged patches and an unburned control forest, taking account of the importance of perches as seed rain sites. We found considerable seed rain by birds in the burned area. Seeds, mostly from Olive trees Olea europaea and Evergreen pistaches Pistacia lentiscus, belonged to plants fruiting only in surrounding unburned areas. Seed rain was heterogeneous, and depended on microhabitat, with the highest seed density in the unburned control forest but closely followed by the wood piles of erosion barriers. In contrast, very low densities were found under perches of standing snags. Furthermore, frugivorous bird richness seemed to be higher in the erosion barriers than elsewhere. Our results highlight the importance of this specific post-fire management in bird-dependent seed rain and also may suggest a consequent heterogeneous distribution of fleshy-fruited plants in burned and managed areas. However, there needs to be more study of the establishment success of dispersed seeds before an accurate assessment can be made of the role of bird-mediated seed dispersal in post-fire regeneration
