Indira Gandhi’s last years in office as India’s prime minister ran from January 1980 to her assassination in October 1984 but until now no book has been devoted to her final term. Among the principal themes discussed in this innovative volume are how Indian politics and society changed in the 1970s, including the state of Emergency (1975-77) Congress’s response to insurgency in Punjab, Assam and Kashmir, the rise of new forms of political mobilisation in the early 1980s and the prime minister’s relationship with the key institutions of state. Maiorano also reveals how Mrs Gandhi’s policies in the 1980s impacted on the big industrialists, the middle class, the rich peasantry and the poor, thereby crucially re-orienting India’s economic strategy. Autumn of the Matriarch is the first major study of MrsGandhi’s last years in power, an important juncture in India’s recent history, as it was then that emerged trends that influenced the country for the next three decades.

DINEOF (Data INterpolating Empirical Orthogonal Functions) is a powerful tool based on EOF decomposition developed at the University of Liege/GHER for the reconstruction of missing data in satellite datasets, as well as for the reduction of noise and detection of outliers. DINEOF is openly available as a series of Fortran routines to be compiled by the user, and as binaries (that can be run directly without any compilation) both for Windows and Linux platforms. In order to facilitate the use of DINEOF and increase the number of interested users, we developed a web-based interface for DINEOF with the necessary parameters available to run high-quality DINEOF analysis. This includes choosing variable within selected dataset, defining a domain, time range, filtering criteria based on available variables in the dataset (e.g. quality flag, satellite zenith angle …) and defining necessary DINEOF parameters. Results, including reconstructed data and calculated EOF modes will be disseminated in NetCDF format using OpenDAP and WMS server allowing easy visualisation and analysis. First, we will include several satellite datasets of sea surface temperature and chlorophyll concentration obtained from MyOcean data centre and already remapped to the regular grid (L3C). Later, based on user’s request, we plan to extend number of datasets available for reconstruction. [less ▲]

The present study focused on re-cancellation behaviors in unilateral neglect (i.e., the tendency to search repeatedly items located on the right side in visual search tasks), and used a neuropsychological approach to identify the cerebral correlates of this deficit. Fourteen patients suffering from left neglect and 14 elderly age-matched controls performed a cancellation task without visual feedback. Neglect patients cancelled fewer targets than controls, and re-cancelled an abnormally high number of targets. Lesion maps were used to compare the location of brain damage in neglect patients with the highest versus the lowest percentage of re-cancellations. Anatomical data revealed that the right insula is commonly damaged in 5 out of 6 patients with the highest re-cancellation percentage, but is spared in the subgroup of patients with the lowest re-cancellation percentage. These results suggest that damage to the right insula may contribute to pathological visual search in spatial neglect, possibly by reducing interaction between the ventral and dorsal attention network (the latter being more directly involved in spatial processes).

Background: Difficulties in everyday life activities are core features of persons diagnosed with schizophrenia. Moreover, patients seem to demonstrate particular difficulties during complex and multitasking activities, such as cooking a meal (Semkovska et al., 2004). Multitasking refers to activities where the person has to: carry out and alternate between different tasks that vary in terms of priority, difficulty and duration; define the tasks’ targets; and where the person is faced with unexpected problems during the realization of these tasks (Burgess, 2000). However, at present, patients’ multitasking capacities have not been adequately examined in the literature due to an absence of suitable assessment strategies. We thus recently developed a computerized real-life activity task designed to take into account the complex and multitasking nature of certain everyday life activities where participants are required to prepare a room for a meeting – the Computerized Meeting Preparation Task (CMPT) Methods: Twenty-one individuals diagnosed with schizophrenia and 20 matched healthy controls completed the CMPT. During the CMPT, participants found themselves in a virtual room that they had to prepare for a meeting while respecting a list of instructions (the placement of the guests, the needed objects, the desired drinks, etc.). Patients were also evaluated with an extensive cognitive battery (assessing executive functions, attention, processing speed and memory), measures of symptomatology and real world functioning. To examine the ecological validity of the CMPT, 14 others patients were recruited and were given the computerized version and a real version of the meeting preparation task. Results: Results demonstrated that performance on the CMPT significantly differentiated patients and healthy controls for the total time to complete task, planning efficiency, and the respect of the instructions. Moreover, these variables were significantly correlated with executive functioning (i.e. cognitive flexibility and planning), suggesting the major implication of these cognitive processes in multitasking activities. Performance on the CMPT also significantly predicted up to 50% of real world functioning. Finally, performances on the computerized version and the real version of the meeting preparation task were highly correlated, suggesting good ecological validity. Discussion: In this study, we created a novel task involving the multitasking nature of real world activities. The results demonstrated that this approach provides a good indication of the real world functioning in patients diagnosed with schizophrenia. Moreover, results suggest a particular implication of executive functioning in multitasking activities. These findings suggest the importance of evaluating multitasking capacities in patients diagnosed with schizophrenia in order to predict real world functioning. [less ▲]

Posée à la littérature, la question du style a, de longue date, suscité engouements et suspicions. Le style littéraire est aujourd’hui considéré comme la trace écrite de l’individu et l’indice d’une distance à l’égard de la langue commune. Une telle conception participe pleinement d’une modernité littéraire ayant érigé la singularité et la nouveauté en valeurs esthétiques. En ce sens, elle est aussi le résultat d’une révision importante, à partir du milieu du XIXe siècle, de l’idéal d’un « style parfait », entendu comme un « bien écrire régi par des règles valables pour tous, respectueux de principes qui semblent défier le temps et les plumes » (Philippe 2013 : 2). Au cours de cette évolution épistémique, de norme, le style devient vecteur de création. La transition a été identifiée tantôt en termes d’« autonomisation » du champ littéraire (Bourdieu), tantôt sous l’angle du « passage d’une littérature-discours à une littérature-texte » (Vaillant) et d’un affranchissement de la rhétorique (Philippe). Dès 1753, Buffon soutient dans son Discours sur le style que « le style est l’homme même », le définissant comme la marque textuelle d’une intériorité auctoriale contrastant avec le caractère commun et extérieur des faits traités. Au cours du XIXe siècle, ces considérations sont passées sous la plume des auteurs eux-mêmes, comme l’attestent la préface d’Edmond de Goncourt à Chérie, qui revendique pour l’écrivain « une langue personnelle, une langue portant [sa] signature », et la conception de Marcel Proust, formulée dans une lettre à madame Straus de 1908, selon laquelle « la seule manière de défendre la langue, c’est de l’attaquer ». L’actualité de la recherche est animée par la question du style à travers de nouvelles perspectives qui proposent de l’étudier de manière extensive, qu’il s’agisse de l’orienter dans une perspective transdisciplinaire empruntant volontiers à l’anthropologie ou de lui conférer une dimension existentielle propre à rendre compte du vécu intime des formes et de leurs significations. Parmi ces approches qui réévaluent la part d’individualité, de créativité ou d’originalité que désigne la notion de style, la sociologie de la littérature n’est pas en reste. Pourtant, le style semble constituer pour elle un point aveugle ou un impensé, sur fond du reproche récurrent qui lui est adressé de négliger la « surface verbale » du texte littéraire (Barthes). C’est donc aux différentes possibilités d’étudier le « style littéraire » en sociologie de la littérature qu’est dédié le présent colloque. Si une place lui a été réservée par la rhétorique et si une discipline à part entière lui a été consacrée, le style semble encore résister à une approche sociologique. Les principaux points d’achoppement concernent l’intégration, dans l’analyse stylistique, des conditions matérielles de production et de réception d’une œuvre, ainsi que les corrélations à établir entre les ordres socio-économique et esthétique. De nombreuses questions restent ainsi posées : comment rendre compte des variations significatives qui engagent à la fois des conceptions artistiques et la structure du champ littéraire ? existe-t-il des définitions concurrentes du style, circulant à un même moment ? comment la sociologie littéraire peut-elle rendre compte des étapes d’une évolution qui va du respect de la norme du bien écrire à la multiplication des expressions individuelles ?

The main purpose of this paper is to argue the extent that earnings management lowers liquidity. It should increase information asymmetry and impair trading liquidity. Using a sample of French firms from 2008 to 2011, we find that firms that manage earnings have wider bid-ask spreads. Our results are robust for both of two well established measures of market liquidity. Therefore the empirical results indicate that firms that exhibit greater earnings management are associated with lower market liquidity. These findings are in line with adverse selection and shed light on the role corporate governance devices can play in the consideration of shareholder interest’s protection, which leads to improved stock market liquidity levels.

It is widely acknowledged that scientific research and science, technology and innovation (STI) policies within the US and the EU have gone through deep changes for about 30 years. Many scholars from science and technology studies and innovation studies have investigated these policy changes, and the publication of “The New Production of Knowledge” (Gibbons et al., 1994) paved the way for vigorous debates on regimes of knowledge production (Hessels & Van Lente, 2008). While different general models were proposed to describe a transition (see, e.g. “mode 2 production of knowledge”, “post normal science”, “strategic science”, “academic capitalism”), these models often posit a dichotomous history, stating that a new regime simply succeeded the previous one (Rip, 2000). In a nutshell, the old regime characterized by strong public intervention and a linear conception of innovation is replaced by a new regime where research and innovation are conceived in systemic terms, regarding their strategic interest for the economy and their societal relevance. This dichotomous conception of STI policy change has been criticized regarding its historical accuracy, e.g. with Pestre (2003), showing that the autonomy of research that characterizes the old regime, or “mode 1” is While the diagnosis of these various science and technology policy studies is not to be dispraised concerning the different effects they emphasize, These macro-perspectives are of little use when it comes to study a local situation they lack acuteness to properly describe and compare empirical observation of such policy changes. This issue is even more salient for empirical work to be conducted in states where multi-level policies are crafted on different, sometimes overlapping national and regional polities. In Belgium, the case in point in my PhD researches, the above-mentioned studies are of little use to characterize the actual state and interplay of Walloon and Flemish STI systems. Hence, there is a need to develop theoretical approaches paying greater attention to local specificities and nuances. My proposal builds on an analysis of STI policies based on coexisting, and sometimes competing “narratives”. In the vein of Stone (1989) and Radaelli (2000), this paper aims at comparing the different policy narratives that circulates as rationale for STI policies in Wallonia, to identify their variants and to study their interplay. Policy narratives give meaning to complex realities, they help making sense of things, but they also contain a plot; they are articulating elements in a logical sequence (with, e.g., causalities, cf. Stone, 1989). As such, they are resources for action: they are descriptive and prescriptive. The broad literature of innovation studies, and its diffusion through the EU or the OECD already provides the Walloon STI stakeholders with different master-narratives (Sum & Jessop, 2013). So far, I could distinguish four different master-narratives in the literature as well as in Walloon stakeholders ‘discourses: • “The Knowledge-based economy” (KBE). KBE seems to be the “dominant” master-narrative today. In a nutshell, this narrative runs as follow (see OECD, 1996): knowledge is the source of economic growth. Since innovation and market success are better encountered through network management and the intertwinement of industry and university, STI institutions must be organized accordingly, in order to achieve a sustained growth and a “better competitiveness” o Variants of this narrative are, e.g. the triple-helix model (Etzkowitz & Leydesdorff, 2000), or National innovation system (Freeman, 1987, Lundvall, 1988). • Grand societal challenges: This recent master-narrative is being promoted by the OECD and the EU (see, e.g., Lund Declaration, 2009). It states that scientific research should benefit of high (public) funding in certain areas, or regarding certain issues. High means for strategic research should help to solve major problems such as climate change, ageing population, energy supply and consumption, cancer, etc. This narrative calls for mission oriented STI policy, so the concern here is not (solely/primarily) economic (Kallerud et al 2013). • “Science, the endless frontier” - continued: famously reported by V. Bush (1945), this master-narrative is still of common use among STI stakeholders. With this narrative, science is considered a public good, the state has to fund it because the linear conception of innovation and serendipity assure technological and economic progress in the end – the rationale is based on economic aspects (the state must fund research because it is a special kind of good and the market efficiency will not work, and basic research is the source of marketable innovation). • “Science for the sake of science”: in this narrative, science is considered as common good regardless of the potential economic impacts (and usefulness to address other societal issues) – we can make a parallel with the idea that artistic creation is worth it: for the beauty, for the critique, science here is considered as a superior activity that brings rationality and knowledge to the society as long as it is independent from “external influences” (Bonneuil & Joly, 2013) – cf. “mertonian Ethos” of Communalism, Universalism, Disinterestedness, Originality and Skepticism. Other examples / variants of this narrative include the idea that science contributes to the greatness of Nation, that science fights obscurantism, and so on and so forth. (examples : peer review, excellence, Copernican revolution are compatible storylines with science for the sake of science : a self-supporting system) While these master-narratives are present in international, academic literature, this paper focuses on their local manifestations. This study compares three critical moments: in different situations, various STI stakeholders (government, researchers, administrative staff, journalists, academic authorities, etc.) publicly expressed their views on the organization and funding of scientific research and innovation activities, and the role of STI within the region. I analyzed the discourses in press articles, policy documents, public statements, allocutions and opinion paper, blogs, etc. I intentionally sampled for heterogeneity since I’m looking for variations and multiple use of narratives. The analysis of the Walloon case permits to overcome the double dichotomy of dominant vs. counter narrative and old vs. new regime. The different narratives, in context, are concurrent but they are not mutually exclusive: while the narratives purport different ideologies, different visions of the role of science and of the state intervention, one is not being erased by the advent of another. Rather, I could find out that narratives “overlap”, and one narrative does not constitute the only resource of a (group of) actors. In situation, the actors use one or multiple narratives, regarding the context, the public, the goal of a policy, etc., in a dynamic of conflict or compromise. This description of the transition is more accurate than the one provided with a sequence of two regimes, since the flexible use of multiple narratives accounts for the continuity of certain institutions (justified by, e.g., a version of “science for the sake of science”) as well as for certain reforms in STI policy (that are inspired by the KBE narrative, for example).

Culicoides biting midges (Diptera: Ceratopogonidae) serve as biological vectors for several pathogens, including the Bluetongue virus and the recently described Schmallenberg virus in northern Europe. These diseases have caused considerable direct and indirect economic losses to the sheep and cattle industries. This study undertaken between August and December 2007 on a sheep farm in the Namur province (Belgium) aims to evaluate Culicoides populations present inside a partially opened sheepfold and in a nearby sheep meadow, using light traps. The comparative analysis of insects trapped at 18 dates at regular intervals showed that Culicoides were most abundant inside this livestock building (17,450 midges) than in surrounding meadow (1,121 midges); this meadow had however a greater species diversity. The two species C. obsoletus and C. scoticus constituting the Obsoletus complex predominated for all trappings and females were much more numerous than males. Important capture of engorged females of the Obsoletus complex inside the sheepfold seems to reflect the possibility of an opportunistic endophagous behavior. Maintaining sheep inside livestock buildings in order to reduce the risk of Culicoides bites – and thus of pathogens transmission – however requires to limit biting midge populations which are likely to enter or to develop inside these buildings. Implementation of effective sanitation and hygiene measures against midges present inside farms, as well as establishing of measures to protect livestock against intrusion and improvement of “midge-proofing” of animal housing are therefore highly recommended.
