Le travail comme expression

Cet article replace la conception du travail developpee par la psychodynamique du travail dans la tradition philosophique de l’expressivisme et soutient la primaute de la conception expressiviste du travail sur la conception classique du travail comme poiesis. A l’issue d’une reconstruction des arguments principaux portant sur l’opposition entre poiesis (travail de production) et praxis (action morale), l’attention sera portee sur les limites de ce modele de conceptualisation du travail. Un modele alternatif est introduit a partir de la prise en compte de plusieurs dimensions du concept d’expression utilise dans le langage courant. Cela nous permet de mettre en evidence ce qui, dans le modele psychodynamique de C. Dejours, est precisement « expressiviste ». Une fois l’origine expressiviste de la theorie de Dejours etablie, plusieurs interpretations des normes d’expression sont presentees, en lien avec l’evaluation des organisations du travail contemporaines.

Automatic Summarization of Online Customer Reviews

Online customer reviews offer valuable information for merchants and potential shoppers in e-Commerce and e-Business. However, even for a single product, the number of reviews often amounts to hundreds or thousands. Thus, summarization of multiple reviews is helpful to extract the important issues that merchants and customers are concerned about. Existing methods of multi-document summarization divide documents into non-overlapping clusters first and then summarize each cluster of documents individually with the assumption that each cluster discusses a single topic. When applied to summarize customer reviews, it is however difficult to determine the number of clusters without the prior domain knowledge, and moreover, topics often overlap with each other in a collection of customer reviews. In this paper, we propose a summarization approach based on the topical structure of multiple customer reviews. Instead of clustering and summarization, our approach extracts topics from a collection of reviews and further ranks the topics based on their frequency. The summary is then generated according to the ranked topics. The evaluation results showed that our approach outperformed the baseline summarization systems, i.e. Copernic summarizer and clustering-summarization, in terms of users’ responsiveness.
Overexpression of vascular endothelial growth factor indicates poor outcomes of glioma: a systematic review and meta-analysis.

BACKGROUND Accumulated studies have revealed that vascular endothelial growth factor (VEGF) plays an essential role in the progression of glioma, but the prognostic significance of VEGF expression for patients with glioma remains unknown. METHOD AND MATERIAL A literature search of public databases (PubMed, ISI Web of Science, Science Direct, Cochrane Central Register of Controlled Trials, Wiley Online Library, China National Knowledge Infrastructure, China Biology Medicine disc, Chongqing VIP and Wan Fang Data) was conducted. A meta-analysis was performed to evaluate the association between the overexpression of VEGF and the survival for the glioma patients. Subsequently we evaluated the impact of VEGF expression on the pathological grade of glioma. RESULTS A total of 32 articles with 2307 cases contributed to this analysis, of which 31 reported overall survival (OS) and 5 reported progression-free survival (PFS). In this meta-analysis, VEGF overexpression significantly identified the unfavorable outcome on OS (HR = 1.647, 95% CI: 1.324~2.048, P < 0.001, Z = 4.48) but not on PFS (HR = 1.021, 95% CI: 0.974~1.070, P = 0.393). Subgroup analyses also revealed that high level of VEGF was associated with the poor OS for the patients with glioma according to region, case number, specimen type, method to detect VEGF and statistical method. Furthermore, the significant correlation was achieved between VEGF expression and the pathological grade of glioma (r = 0.307, P < 0.001). CONCLUSION This study suggests that VEGF expression is significantly correlated with the glioma progression and may be a valuable prognostic factor on OS for the glioma patients.
Towards a voltage regulation market

In this work, we propose a possible voltage support or voltage regulation market in which voltage service providers (VSPs) will compete for an opportunity to provide voltage support or regulation by using voltage support devices. We assume that voltage regulation market is a separate but complementary market to existing energy markets (day-ahead and real time markets). An independent system operator (ISO) will decide when the voltage regulation market is to be launched. ISO will determine the required voltages (in p.u) at some nodes and clear the market based on the submitted bids and offers by the voltage service providers. ISO can anticipate the low-voltage situation ex-ante at some locations and can initiate the voltage regulation market. The voltage regulation market problem was formulated as nonlinear AC-OPF model and was solved using improved differential evolutionary algorithm. We used an IEEE 14 bus system as a test system in which the voltage regulation market clears. We showed that the development of voltage regulation market is of practically possible and can improve both social welfare and system condition.
A new approach to the solution of Maxwell's equations for low frequency and high-resolution biomedical problems

High spatial resolution studies of the interaction of the human body with electromagnetic waves of low frequency presents a difficult computational problem. As these studies typically require at least $10^4$ points per wavelength, a huge number of time steps would be needed to be able to use the finite difference time domain method (FDTD). In this paper, a new technique is described, which allows the FDTD method to be efficiently applied over a very large frequency range, including low frequencies. In the method, no alterations to the properties of either the source or the transmission media are required. The method is essentially frequency independent and has been verified against analytical solutions within the frequency range 50 Hertz to 1 Gigahertz. As an example of the lower frequency range, the method has been applied to the simulation of electromagnetic field behavior in the human body exposed to the pulsed magnetic field gradients of a magnetic resonance image (MRI) system.
Rosiglitazone and cardiovascular risk.

In this issue of the Journal, Nissen and Wolski1 report the results of a meta-analysis of treatment trials of rosiglitazone, as compared either with other therapies for type 2 diabetes or with placebo. Eligible studies included randomized trials that lasted for at least 24 weeks. The prespecified primary end points of interest were myocardial infarction and death from cardiovascular causes. The authors identified 42 eligible studies, many of which were small or short-term trials, that included a total of 158 myocardial infarctions and 61 deaths from cardiovascular causes. They used the Peto method to combine data from the trials. In .
Transcriptional and post-transcriptional regulation of prolactin during the turkey reproductive cycle.

The present study examined turkey prolactin (PRL) transcription and PRL mRNA stability during different reproductive stages. Nuclear run-on transcription assays were performed using isolated nuclei from pituitaries of turkeys at different reproductive stages. Meanwhile, cytoplasmic PRL mRNA and plasma PRL were measured by slot blot and RIA respectively. The PRL transcription, pituitary cytoplasmic PRL mRNA abundance and plasma PRL levels increased after photostimulation and peaked at the incubating stage (P < 0.05). A decrease in PRL transcription, pituitary cytoplasmic PRL mRNA and plasma PRL (P < 0.05) was observed during the transition from incubation to photorefractoriness. Nest-deprivation reduced circulating PRL (P < 0.05), whereas pituitary cytoplasmic PRL mRNA and PRL transcription were not significantly altered from those in incubating birds (P > 0.05). The half-life of PRL mRNA was determined in pituitaries of non-photostimulated, laying, incubating and photorefractory hens. Primary pituitary cell cultures were treated with the transcription inhibitor actinomycin-D and the decay of the pre-existing PRL mRNA was quantified using Northern blot analysis. The PRL mRNA half-life was 1.5- and 1.4-fold greater in incubating and laying birds respectively than in non-photostimulated turkeys (P < 0.05). The half-life of PRL mRNA in photorefractory and incubating hens was similar in spite of great differences in pituitary PRL mRNA steady-state levels and PRL transcription. Our data suggest that photoinduced changes in pituitary PRL mRNA and plasma PRL are due to changes in both PRL transcription and PRL mRNA stability. Nest-deprivation inhibits the PRL releasing mechanism(s) independently of PRL transcription in turkeys.
Molecular Determinants for Subcellular Trafficking of the Malarial Sheddase PfSUB2

The malaria merozoite invades erythrocytes in the vertebrate host. Iterative rounds of asexual intraerythrocytic replication result in disease. Proteases play pivotal roles in erythrocyte invasion, but little is understood about their mode of action. The Plasmodium falciparum malaria merozoite surface sheddase, PfSUB2, is one such poorly characterized example. We have examined the molecular determinants that underlie the mechanisms by which PfSUB2 is trafficked initially to invasion‐associated apical organelles (micronemes) and then across the surface of the free merozoite. We show that authentic promoter activity is important for correct localization of PfSUB2, likely requiring canonical features within the intergenic region 5′ of the pfsub2 locus. We further demonstrate that trafficking of PfSUB2 beyond an early compartment in the secretory pathway requires autocatalytic protease activity. Finally, we show that the PfSUB2 transmembrane domain is required for microneme targeting, while the cytoplasmic domain is essential for surface translocation of the protease to the parasite posterior following discharge from micronemes. The interplay of pre‐ and post‐translational regulatory elements that coordinate subcellular trafficking of PfSUB2 provides the parasite with exquisite control over enzyme–substrate interactions.
The ModFM Synthesis Vocoder

Vocoders have been practical tools for synthesis and processing since the original voice encoder by Homer Dudley in the 1930s . They enable the transformation and reproduction of an input sound by the manipulation of its spectral envelope. This paper presents a new variation on the principle utilising the technique of Modified FM (ModFM) synthesis for sound generation. The general design of the vocoder is introduced, followed by a non-mathematical introduction to the ModFM synthesis algorithm. The article is completed with an outline of applications and a discussion of some basic examples of the vocoder operation.
A Printed Elliptical Monopole Antenna With Modified Feeding Structure for Bandwidth Enhancement

A printed extremely wideband antenna is studied and results presented. The proposed antenna is composed of a trapezoid ground plane and an elliptical monopole patch which is fed by a modified tapered CPW line. The simulated and measured results agree well and it indicates the antenna has a measured impedance bandwidth from 1.02 GHz to 24.1 GHz with a VSWR ≤ 2. It is shown that the antenna radiation pattern is nearly omni-directional over the entire frequency band and the antenna is suitable for wireless communication applications.
Treatment of Myasthenia Gravis Acute Exacerbations with Intravenous Immunoglobulin

The results of four randomized controlled trials were examined to assess the efficacy of intravenous immunoglobulin (IVIG) for myasthenia gravis (MG) acute exacerbations. The first trial compared plasma exchange (PE) and IVIG in 87 patients. At day 15, the mean change in the Myasthenic Muscular Score (MMS) was 16.6 (95% CI 11.6–21.6) in the PE group and 15.6 (95% CI 10.9–20.3) in the IVIG group (Wilcoxon signed rank test, P = 0.65). The second trial compared IVIG to oral methylprednisolone, and 33 patients were included. The mean (SD) sum of the two most pathological items of the Quantitative Myasthenia Gravis Score (QMGS) at day 0 was 3.9 (1.1) for the IVIG group and 4.2 (0.7) for the methylprednisolone group. At day 14, these values were 2.9 (1.4) for the IVIG group and 2.8 (1.1) for the methylprednisolone group. The third trial compared IVIG 2 g/kg versus placebo for MG worsening. The mean change in QMGS at day 14 was –2.54 in the IVIG group and –0.89 in the placebo group (P= 0.047). A significant IVIG treatment effect was observed only in patients with more severe disease; the mean difference was −0.10 for mild MG (P= 0.914) and −3.39 for moderate to severe MG (P= 0.010). The last trial compared IGIV 2 g/kg versus 1 g/kg for MG acute exacerbation in 173 patients. The mean MMS change in both groups was similar (difference = 3.84; 95% CI −1.03 to 8.71; P = 0.12). In conclusion, IVIG may be used as treatment for MG acute exacerbations. IVIG at a dose of 1 g/kg may be sufficient.
The Organizational Learning Survey: A Re-Evaluation of Unidimensionality

An earlier study by Chakrabarty and Rogé evaluated the dimensionality of the Organizational Learning Survey for assessing the learning capability of organizations developed by Goh and Richards. In this paper, the survey was re-evaluated for unidimensionality using both exploratory and confirmatory factor analysis. Retaining 18 of the original 21 items was sufficient to establish unidimensionality. A number of different confirmatory models validated the unidimensional measurement model on two independent data sets. Implications for further empirical research using this inventory are discussed.
Effect of post hatch feed deprivation on yolk-sac utilization and performance of young broiler chickens

An experiment was conducted to study the effect of post-hatch feed deprivation on yolk sac utilization and subsequent performance of young broiler chickens (280) up to 35 days of age. The experimental treatments included access to feed at 8 h intervals after hatch, up to 48 h (0, 8, 16, 24, 32, 40 or 48 h). Water was offered ad libitum to all the groups immediately after placement. Results indicated that chicks with access to feed immediately after hatch used up the residual yolk more quickly. Access to feed between 8-24 h post-hatch, supported faster utilization of residual yolk compared to those chicks that remained unfed for 40-48 h (p 10.5%) of broilers at 5 weeks of age.
Design of substrate integrated waveguides structures based on stop-band response FSSs (SBFSS-SIW)

A novel combination of Substrate Integrated Waveguide (SIW) and Frequency Selective Surface (FSS) is proposed. The FSS operates in its Stop-Band and acts as metal conductor plates of the SIW. The Substrate Integrated Waveguide using Frequency Selective Surfaces in Stop-Band (SBFSS-SIW) preserve the propagation properties and the dimensions of the conventional SIW, and have periodic isolated pads that could allow the direct integration of biased active and passive devices on the SIW surface. A set of SBFSS-SIWs for X-band have been designed, simulated and experimentally measured to demonstrate that SBFSS-SIWs can behave similar to conventional SIW structures.
Systemic sclerosis: patients' perceptions of their condition.

OBJECTIVE To examine patients' beliefs about systemic sclerosis (SSc) and to investigate the relationship between these beliefs, symptom report, and clinical and demographic variables. METHODS A total of 49 patients (7 male, 42 female) with SSc underwent clinical examination and completed the Revised Illness Perception Questionnaire. This measure assesses beliefs about symptoms, chronicity or recurrence of the condition, consequences, personal and treatment control, illness coherence, perceived causes of the condition, and patients' emotional response to their condition. RESULTS The symptoms patients most frequently associated with their SSc were stiff joints (79%), pain (75%), and fatigue (75%). The most commonly reported causes of SSc were stress (53%), altered immunity (49%), and chance or bad luck (46%). More than 96% of patients believed that their condition would be chronic and 78% believed that the condition had serious consequences on their lives. Patients with diffuse cutaneous SSc reported more significant consequences of the condition and less personal control of their SSc compared with patients with limited cutaneous disease. There were no significant differences in illness beliefs between patients with nonsevere and severe ischemia. Multiple regression analyses indicated that illness beliefs, in particular perceived consequences associated with the condition, accounted for a significant proportion of the variance in emotional response to the condition. CONCLUSIONS The beliefs held and symptoms experienced by patients with SSc are not ruled by disease subtype, skin score, functional ability, or severity of digital ischemia. This suggests patients' beliefs and emotional response are associated with the meaning they ascribe to their condition rather than its severity.
Microfabrication Technology of Biodegradable Polymers for Interconnecting Microstructures

A microtechnology for synthetic biodegradable polymers has been developed to fabricate three-dimensionally (3-D) shaped and microstructured multilayer constructs for biomedical applications. A unique micromolding method is proposed to create deep and interconnecting microstructures which facilitate cellular scale interconnection across the layers for cell-to-cell communication and the supply of nutrients and oxygen. A geometrical condition and molding setup for interconnecting microstructuring are described and demonstrated experimentally. Furthermore, various types of synthetic biodegradable polymers are explored and compared with regard to the behavior during the proposed process. Considering the thermal instability of synthetic biodegradable polymers, it is also confirmed that the proposed process does not affect the property of the polymers. Finally, microfabricated 3-D multilayer constructs is presented to demonstrate the feasibility of the technology as a unique scaffolding method
Measurement of growth and iron deposition in Sphaerotilus discophorus

Aspects of the physiology of iron deposition of an iron-precipitating strain of Sphaerotilus were investigated in laboratory culture to characterize the process. Measurement of growth (incorporated L-[3H]alanine) and iron deposition (incorporated 59Fe) demonstrated that Sphaerotilus exhibit a characteristic temporal pattern of iron deposition, which is delayed until the latter portion of the exponential or the onset of the stationary growth phase. The growth rate (mu=0.17 h-1) was apparently independent of the iron concentration in the medium. There was, furthermore, no direct correlation between the iron concentration and final cell protein yield. It was concluded from experiments involving growth on artificial substrata (glass cover slips) that sessile populations derived no phsiological advantage (manifested as differences in growth rates) over free-living cells. There was no difference in the rate or onset of iron deposition of attached compared to suspended cells. Blocking of protein synthesis by the addition of chloramphenicol suggested that, once iron deposition was initiated, continued protein synthesis was not required for full expression of this capability. The results suggested that iron deposition may be possibly mediated by certain of the constituents of the organism's sheath.
Structure–activity Relationships of Amyloid Beta‐aggregation Inhibitors Based on Curcumin: Influence of Linker Length and Flexibility

Self‐assembly of amyloid beta into fibrillar plaques is characteristic of Alzheimer’s disease and oligomers of this peptide are believed to be involved in neurodegeneration. Natural organic dyes, such as congo red and curcumin, bind tightly to amyloid beta and, at higher concentrations, block its self‐assembly. The ability of these molecules to prevent amyloid accumulation has generated interest in understanding which of their structural features contribute to inhibitory potency. In general, amyloid beta ligands tend to be flat, planar molecules with substituted aromatic end groups; however, a comprehensive structure–activity study has not been reported. To better understand these ligands, we surveyed the effect of three prominent features on inhibition of amyloid aggregation: the presence of two aromatic end groups, the substitution pattern of these aromatics, and the length and flexibility of the linker region. We found that modification of any one of the modules has profound effects on activity. Further, we report that the optimal length of the linker lies within a surprisingly narrow regime (6–19 Å). These results offer insight into the key chemical features required for inhibiting amyloid beta aggregation. In turn, these findings help define the nature of the docking site for small molecules on the amyloid beta surface.
Temporal and Spatial Variation in Survivorship of Diamondback Terrapins (Malaclemys terrapin)

Abstract The diamondback terrapin (Malaclemys terrapin) is a species of conservation concern that has experienced noticeable declines throughout its range. Mark–recapture studies have been conducted on terrapins at Kiawah Island, South Carolina, since 1983, and during the early 1990s, this population began to decline. Our objectives were to evaluate current spatial and temporal variation in survivorship and compare current estimates of survivorship with those calculated from 1983 to 1999 in a previous study. We used an 11-year data set (2003 to 2013) in a capture–mark–recapture analysis to estimate the survivorship of terrapins in 5 creeks. Among creeks, annual survivorship estimates ranged from 61% to 82% with no difference between the sexes. Survivorship was lower than that documented for this population in the early 1990s. Recent anthropogenic habitat modification, such as the construction of docks, roads, and housing developments, as well as activities such as crab-trapping, likely play a role in low annual survivorship. Results from this long-term study are essential for understanding terrapin population status and can inform conservation and coastal ecosystem management.
Reducing ultraviolet radiation exposure in children.

BACKGROUND Project SUNWISE evaluated the effectiveness of a multicomponent intervention in reducing children's ultraviolet radiation (UVR) exposure. METHODS Across four YMCAs, 48 aquatics classes (N = 169 children, mean age = 7) were randomly assigned to either the intervention or the control condition. The 6-week intervention included a UVR reduction curriculum presented at poolside by aquatics instructors and home-based activities for children and their parents. Outcome measures were (a) tanness-associated skin color dimensions assessed with a colorimeter, (b) specific daily solar protection behaviors of children as reported by parents, and (c) general solar protection behaviors. RESULTS Controlling for intraclass clustering in all analyses, at posttest, no statistically significant between-group differences were found in tanness, daily solar protection scores, or general sunscreen use. The intervention group showed significantly greater general hat use relative to controls. CONCLUSIONS The intervention failed to impact most of the outcome measures. Supplementing the behavior-focused intervention package with environmental supports may be warranted.
