La profession au temps de la flexibilité. Vers une approchepragmatique de la notion

La notion de profession est utilisee et problematisee dans de nombreux travaux sociologiques. Elle peut y apparaitre en tant que libelle d’un groupe d’individu, en tant que qualificatif d’une pratique de travail specifique, en tant qu’element socialisateur, variable explicative de certains comportements, etc. Dans l’elaboration d’un projet de recherche sur le theme de l’articulation travail/famille ou nous nous sommes interroges sur l’effet que la profession pouvait avoir sur l’usage de dispositifs institutionnels tels que le conge parental parmi les membres de trois professions (infirmieres, assistants sociaux et policiers), une problematisation de la notion nous paraissait necessaire avant de discuter de la mediation professionnelle. C’est a une reflexion sur ce qui effectue cette mediation que nous voulons nous atteler. Cette question se pose avec d’autant plus d’acuite que depuis quelques temps, la notion de profession est percue comme mise a mal par une evolution du monde du travail vers plus de flexibilite. Dans cet article, nous saisirons donc l’occasion de ce constat en terme de flexibilite pour reprendre a nouveau frais la question de la profession et ce, dans une perspective qui vise a en faire une notion viable pour une recherche qui traite de la mediation professionnelle. On verra d’abord en quoi la profession peut se reveler etre une entite instable a partir des travaux de plusieurs auteurs qui traitent du monde du travail. Si la plupart s’accordent sur le fait que quelque chose a change dans le monde du travail par rapport a d’autres moments, et qu’il y a donc pertinence a repenser nos outils pour l’apprehender, c’est sur la mesure de l’ampleur de cette reflexion que les romains s’empoignent. Ayant fait un rapide tour d’horizon des constats poses sur l’avenement d’un contexte flexible, nous tenterons de formaliser les consequences de cette instabilite sur la profession – en tant que la notion est utilisee par des sociologues, et surtout en tant qu’elle est vecue par les individus. Dans la derniere partie, nous proposerons quelques pistes de sortie pour une refonte pragmatique de l’outil, en nous centrant sur les trois professions qui nous occupent dans le cadre de cette recherche.
Effect of Uncertainty on the Reaction Response in Fencing

Purpose: The objective was to determine the way in which the level of uncertainty produced during the execution of a lunge attack with target change (two or four possible responses) affects reaction-response time parameters and kinematic factors involved in the technical coordination of the attack. Method: Seventeen fencers from the Spanish National Men's Fencing Team participated in the study, which involved performing a lunge attack against a moving circle as fast as possible, while attempting to place the tip of the sword inside the circle that appeared in the plastron's center of symmetry. Two force platforms were used to record the anteroposterior component of force and the initiation of movement. Kinematics were measured with a three-dimensional motion-capture system that recorded the spatial positions of 11 markers. An electronic signal was used to time-synchronize all of the systems. Results:The results demonstrate a significant increase in reaction time, p < . 01, and choice reaction time, p < . 001, when uncertainty increases, while movement time, precision, and segmental participation sequence during movement are not affected when uncertainty increases.Conclusion: It is worth stressing the importance of uncertainty-reduction strategies for fencers' performance to reduce the reaction-response time. Although increased uncertainty has little influence over precision and segmental participation sequence of the movement pattern used in attacks executed by elite fencers, caution should be used when generalizing these results for fencers of a lower technical level than that of the participants in this study.
iSentenizer: An incremental sentence boundary classifier

In this paper, we revisited the topic of sentence boundary detection, and proposed an incremental approach to tackle the problem. The boundary classifier is revised on the fly to adapt to the text of high variety of sources and genres. We applied i+Learning, an incremental algorithm, for constructing the sentence boundary detection model using different features based on local context. Although the model can be easily trained on any genre of text and on any alphabet language, we emphasize the ability that the classifier is adaptable to text with domain and topic shifts without retraining the whole model from scratch. Empirical results indicate that the performance of proposed system is comparable to that of similar systems.
People are processors: coalitional auctions for complex projects

To successfully complete a complex project, be it a construction of an airport or of a backbone IT system, agents (companies or individuals) must form a team (a coalition) having required competences and resources. A team can be formed either by the client based on individual agents' offers (centralized formation); or by the agents themselves (decentralized formation) bidding for a project as a consortium---in that case many feasible teams compete for the employment contract. In these models, we investigate rational strategies of the agents (what salary should they ask? with whom should they team up? ) under different organizations of the market. We propose concepts allowing to characterize the stability of the winning teams. We show that there may be no (rigorously) strongly winning coalition, but the weakly winning and the auction-winning coalitions are guaranteed to exist. In a general setting, with an oracle that decides whether a coalition is feasible, we show how to find the winning coalitions with a polynomial number of calls to the oracle. We also determine the complexity of the problem in a special case in which a project is a set of independent tasks. Each task must be processed by a single agent, but processing speeds differ between agents and tasks.
Towards More Reality in the Recognition of Emotional Speech

As automatic emotion recognition based on speech matures, new challenges can be faced. We therefore address the major aspects in view of potential applications in the field, to benchmark today's emotion recognition systems and bridge the gap between commercial interest and current performances: acted vs. spontaneous speech, realistic emotions, noise and microphone conditions, and speaker independence. Three different data-sets are used: the Berlin Emotional Speech Database, the Danish Emotional Speech Database, and the spontaneous AIBO Emotion Corpus. By using different feature types such as word- or turn-based statistics, manual versus forced alignment, and optimization techniques we show how to best cope with this demanding task and how noise addition or different microphone positions affect emotion recognition.
Changes in nitrogen metabolism and antioxidant enzyme activities of maize tassel in black soils region of northeast China

Two varieties of maize (Zea mays L.) grown in fields in black soils of northeast China were tested to study the dynamic changes of nitrogen metabolism and antioxidant enzyme activity in tassels of maize. Results showed that antioxidant enzyme activity in tassels of maize increased first and then decreased with the growing of maize, and reached peak value at shedding period. Pattern of proline was consistent with antioxidant enzyme activity, showing that osmotic adjustment could protect many enzymes, which are important for cell metabolism. Continuous reduction of soluble protein content along with the growing of maize was observed in the study, which indicated that quantitative material and energy were provided for pollen formation. Besides, another major cause was that a large proportion of nitrogen was used for the composition of structural protein. Nitrate nitrogen concentrations of tassels were more variable than ammonium nitrogen, which showed that nitrate nitrogen was the favored nitrogen source for maize.
Reproductive Biology and Endocrinology Role of Oxidative Stress in Female Reproduction

In a healthy body, ROS (reactive oxygen species) and antioxidants remain in balance. When the balance is disrupted towards an overabundance of ROS, oxidative stress (OS) occurs. OS influences the entire reproductive lifespan of a woman and even thereafter (i.e. menopause). OS results from an imbalance between prooxidants (free radical species) and the body's scavenging ability (antioxidants). ROS are a double-edged sword – they serve as key signal molecules in physiological processes but also have a role in pathological processes involving the female reproductive tract. ROS affect multiple physiological processes from oocyte maturation to fertilization, embryo development and pregnancy. It has been suggested that OS modulates the age-related decline in fertility. It plays a role during pregnancy and normal parturition and in initiation of preterm labor. Most ovarian cancers appear in the surface epithelium, and repetitive ovulation has been thought to be a causative factor. Ovulation-induced oxidative base damage and damage to DNA of the ovarian epithelium can be prevented by antioxidants. There is growing literature on the effects of OS in female reproduction with involvement in the pathophsiology of preeclampsia, hydatidiform mole, free radical-induced birth defects and other situations such as abortions. Numerous studies have shown that OS plays a role in the pathoysiology of infertility and assisted fertility. There is some evidence of its role in endometriosis, tubal and peritoneal factor infertility and unexplained infertility. This article reviews the role OS plays in normal cycling ovaries, follicular development and cyclical endometrial changes. It also discusses OS-related female infertility and how it influences the outcomes of assisted reproductive techniques. The review comprehensively explores the literature for evidence of the role of oxidative stress in conditions such as abortions, preeclampsia, hydatidiform mole, fetal embryopathies, preterm labour and preeclampsia and gestational diabetes. The review also addresses the growing literature on the role of nitric oxide species in female reproduction. The involvement of nitric oxide species in regulation of endometrial and ovarian function, etiopathogenesis of endometriosis, and maintenance of uterine quiescence, initiation of labour and ripening of cervix at parturition is discussed. Complex interplay between cytokines and oxidative stress in the etiology of female reproductive disorders is discussed. Oxidant status of the cell modulates angiogenesis, which is critical for follicular growth, corpus luteum formation endometrial differentiation and embryonic growth is also highlighted in the review. Strategies to overcome oxidative stress and enhance fertility, both natural and assisted are delineated. Early interventions being …
Eosinophilic Gastrointestinal Disorder Presenting as Intractable Vomiting and Ascites in a Young Girl

Eosinophilic gastrointestinal disorder (EGID) is a rare disease in children that affects the bowel wall, with eosinophilic infiltration in the absence of any other causes for eosinophilia. The etiology remains unknown, but allergies and immunological imbalance are suspected triggers. We encountered a case of serosal EGID presenting as intractable vomiting and ascites in a 9-year-old girl, after influenza virus infection. Peripheral eosinophilia was not present. The diagnosis was confirmed by biopsy of the bowel wall through laparotomy and endoscopy, and controlled by 2 courses of steroid therapy due to recurring symptoms. Influenza virus infection was assumed to play a role in the onset of EGID through a Th2 response that stimulated eosinophilic infiltration in the GI tract. We therefore report this case along with a literature review.
Proposal for a conformal field theory interpretation of Watts’ differential equation for percolation

G M T Watts established that in two-dimensional critical percolation the crossing probability Πhv satisfies a fifth-order differential equation which includes another one of third order whose independent solutions describe the physically relevant quantities 1,Πh,Πhv. We will show that this differential equation can be derived from a level three null vector condition for a rational c = −24 conformal field theory and motivate how this solution may be fitted into known properties of percolation.
La subtitulación aficionada de animación japonesa: una aproximación intertextual

The present article purports to approach amateur subtitling of Japanese animation (asja) from an intertextual perspective. With this we aim to show the adequacy of the theoretical framework here used for the study of discursive activities of the complex nature of asja, as well as to provide the basis for a proper account of this particular practice.
Adaptive LSTAR Model for Long-Range Variable Bit Rate Video Traffic Prediction

Static bandwidth allocation for variable bit rate (VBR) video traffic forfeits the available bandwidth. Prediction of the next frame size is thus useful in dynamic bandwidth allocation. It has been shown that VBR video traces are long-range dependent, which makes one-frame-ahead prediction insufficient for dynamic bandwidth allocation. Several studies have been conducted based on the linear autoregressive (AR) model to address VBR traffic prediction. In this paper, we propose the use of a nonlinear model from the AR family called logistic smooth transition autoregressive (LSTAR) to predict VBR video traffic. Furthermore, we introduce adaptive algorithms, including least mean square (LMS), normalized LMS (NLMS), kernel LMS (KLMS), and normalized KLMS (NKLMS), to obtain the parameters of the LSTAR model used in long-range VBR traffic prediction. In the proposed model, we do not separate traffic of different frame types and use only one predictor, which results in lower computational complexity. The performance of the proposed predictor for different prediction steps was evaluated and compared with recently introduced predictors. The results indicate that the proposed nonlinear LSTAR-based predictor yields better results than the optimum linear AR predictor, i.e., Wiener–Hopf and others.
Anti‐Cancer Drugs Reactivate Tumor Suppressor miR‐375 Expression in Tongue Cancer Cells

Head and neck cancer is one of the deadliest malignant diseases and chemotherapy is a common treatment option. Despite the development of chemotherapies for several decades, how these drugs affect the dynamics of gene regulation is still largely unknown. In our previous study, miR‐375 was shown to be underexpressed in oral cancers and thus unable to serve as a tumor suppressor microRNA to regulate certain putative oncogenes. In this study, we found that common anti‐cancer drugs reactivated miR‐375 in tongue cancer cells. Incubation of tongue cancer cells CAL 27 and SCC‐25 in medium containing doxorubicin, 5‐fluorouracil, trichostatin A, or etoposide significantly increased the expression of miR‐375 and its primary transcript pri‐miR‐375. The dose‐ and time‐dependent effects of doxorubicin in CAL 27 were demonstrated by miR‐375 increases in response to the drug. Significant suppression of pri‐miR‐375 expression was observed in human tongue cancer specimens and this decrease was more prominent in advanced stage tumors. Bioinformatics from four publicly available mRNA microarray data sets suggested that these candidate miR‐375 targets are mainly involved in cancer biology, indicating that these targets are likely to be suppressed via miR‐375 due to the treatment with these drugs. Together, our data suggest that the four anti‐cancer drugs examined in this study induce the expression of tumor suppressor miR‐375 in tongue cancer. J. Cell.

A Fundamental Study of Wing Actuation for a 6-in-Wingspan Flapping Microaerial Vehicle

This paper investigates the hovering efficiency of the wing-actuation parameters of a flapping microaerial vehicle with a two-degree-of-freedom (2-DOF) driving mechanism, using finite-element analysis based on the arbitrary Lagrangian-Eulerian method (ALE-FEA). A 75-mm-long wing and multilinkage mechanism that consisted of thin plates and films was employed. It generated a flapping motion that consisted of horizontal stroke of the wing and twist around its leading edge, which were activated by the rotations of two motors. The application of the ALE-FEA was successfully extended to the structural behavior of the driving mechanism. The behaviors of the linkage mechanism, the wing, and its surrounding airflow were reproduced numerically. Various parameters were obtained, some of which were difficult to measure in real experiments, such as the pressure distribution on the wing. For cases of 25 combinations of wings' twist angles and flapping periods, lift forces and energy requirements for the motors were determined. Based on these results, the most efficient flapping combination that generated 1 gf lift force was calculated. In contrast with the combination that created the strongest lift force, the combination of a larger twist angle and a faster flapping cycle was found to provide the most efficient flight.
Wahrnehmung sozialer Normen und Regeln in spieltheoretischer Perspektive bei psychischen Störungen

Zusammenfassung Menschliches Zusammenleben erfordert die Fähigkeit sich in andere hineinzuversetzen, Kompromisse zu schließen und gemeinsame Normen und Werte zu entwickeln. Autismus und Schizophrenien stellen schwere psychische Erkrankungen dar, die sich auch in erheblichen Schwierigkeiten in der sozialen Interaktion und der Verletzung von Regeln und Konventionen manifestieren. Spieltheoretische Szenarien ermöglichen es, diese Aspekte experimentell zu untersuchen und Schlussfolgerungen über Gemeinsamkeiten und Unterschiede der beiden Störungsbilder auf Verhaltensebene zu ziehen. Funktionell-bildgebende Verfahren bieten die Möglichkeit die zugrunde liegenden neuronalen Mechanismen aufzuklären. Die vorliegende Übersichtsarbeit stellt einige spieltheoretische Modelle zum Verständnis von Altruismus und sozialen Normen in ihren evolutionsbiologischen und ontogenetischen Bezügen vor und stellt erste Untersuchungen bei Autismus und Schizophrenien vor, die dazu dienen, soziale Verhaltensstörungen der betroffenen Patienten besser verstehen zu können.
A novel dynamic state feedback controller for discrete-time T-S fuzzy affine systems

This paper proposes a robust H∞ dynamic state feedback (DSF) controller for discrete-time nonlinear systems through Takagi-Sugeno (T-S) fuzzy-affine models. On the basis of piecewise fuzzy quadratic Lyapunov functions (PFQLFs) and some convexification techniques, sufficient conditions for the DSF controller synthesis are obtained in terms of a set of linear matrix inequalities (LMIs). Two simulation examples are given to verify the feasibility of the developed method.
Trees increase their P:N ratio with size.

AIM Phosphorus (P) tends to become limiting in aging terrestrial ecosystems, and its resorption efficiency is higher than for other elements such as nitrogen (N). We thus hypothesized that trees should store more P than those other elements such as N when tree size increases and that this process should be enhanced in slow-growing late successional trees. LOCATION Catalan forests. METHODS We have used data from the Catalan Forest Inventory that contains field data of the P and N contents of total aboveground, foliar and woody biomasses of the diverse Mediterranean, temperate and alpine forests of Catalonia (1018 sites). We used correlation and general lineal models (GLM) to analyze the allometric relationships between nutrient contents of different aboveground biomass fractions (foliar, branches and stems) and total aboveground biomass. RESULTS Aboveground forest P content increases proportionally more than aboveground forest N content with increasing aboveground biomass. Two mechanisms underlie this. First, woody biomass increases proportionally more than foliar biomass having woody biomass higher P:N ratio than foliar biomass. Second, wood P:N ratio increases with tree size. These results are consistent with the generally higher foliar resorption of P than of N. Slow-growing species accumulate more P in total aboveground with size than fast-growing species mainly as a result of their large capacity to store P in wood. MAIN CONCLUSIONS Trees may have thus developed long-term adaptive mechanisms to store P in biomass, mainly in wood, thereby slowing the loss of P from the ecosystems, reducing its availability for competitors, and implying an increase in the P:N ratio in forest biomass with aging. This trend to accumulate more P than N with size is more accentuated in slow-growing, large, long-living species of late successional stages. This way they partly counterbalance the gradual decrease of P in the soil.
Estrogen receptor immunocytochemistry in paraffin embedded tissues with ER1D5 predicts breast cancer endocrine response more accurately than H222Spγ in frozen sections or cytosol‐based ligand‐binding assays

Historically, estrogen receptor (ER) determinations have been made by the ligand‐binding assay of tumor homogenates, primarily by the dextran‐coated charcoal method (DCC). Immunocytochemical assays (ICA) for ER are more recent and have been executed mostly on frozen sections with the monoclonal antibody H222Spγ (H222). Lately, new monoclonal antibodies derived by recombinant ER technology have been developed that work well on paraffin embedded, formalin fixed tissue sections. However, there is little information as to whether such assays prognosticate endocrine response.
Tight conditional lower bounds for counting perfect matchings on graphs of bounded treewidth, cliquewidth, and genus

By now, we have a good understanding of how NP-hard problems become easier on graphs of bounded treewidth and bounded cliquewidth: for various problems, matching upper bounds and conditional lower bounds describe exactly how the running time has to depend on treewidth or cliquewidth. In particular, Fomin et al. (2009, 2010) have shown a significant difference between these two parameters: assuming the Exponential-Time Hypothesis (ETH), the optimal algorithms for problems such as M ax C ut and E dge D ominating S et have running time 2O(t)nO(1) when parameterized by treewidth, but nO(t) when parameterized by cliquewidth. In this paper, we show that a similar phenomenon occurs also for counting problems. Specifically, we prove that, assuming the counting version of the Strong Exponential-Time Hypothesis (#SETH), the problem of counting perfect matchings • has no (2 --- e)knO(1) time algorithm for any e > 0 on graphs of treewidth k (but it is known to be solvable in time 2knO(1) if a tree decomposition of width k is given), and • has no O(n(1-e)k) time algorithm for any e > 0 on graphs of cliquewidth k (but it can be solved in time O(nk+1) if a k-expression is given). A celebrated result of Fisher, Kasteleyn, and Temperley from the 1960s shows that counting perfect matchings in planar graphs is polynomial-time solvable. This was later extended by Gallucio and Loebl (1999), Tesler (2000) and Regge and Zechina (2000) who gave 4k · nO(1) time algorithms for graphs of genus k. We show that the dependence on the genus k has to be exponential: assuming #ETH, the counting version of ETH, there is no 2O(k) · nO(1) time algorithm for the problem on graphs of genus k.
