Utilisation de la spectrométrie infrarouge pour une quantification rapide du taux d’humidité dans des fibres végétales

Les fibres vegetales sont une alternative possible aux fibres de verre utilisees classiquement comme renforts dans certains materiaux composites. En plus d’avantages environnementaux, leur faible densite leur confere des proprietes mecaniques specifiques elevees. Cependant, leur comportement hydrophile marque entraine une forte absorption d’eau lors d’une utilisation en environnement humide, ce qui peut modifier leurs proprietes mecaniques. La comprehension de ces mecanismes d’absorption d’humidite est donc indispensable a leur maitrise. Dans ce travail, l’absorption d’eau a ete etudiee par spectroscopie infrarouge a transformee de Fourier sur des fibres de lin, chanvre et sisal. Ces fibres ont ete soumises a des conditions hygrometriques controlees. Les spectres infrarouges des echantillons ont ete enregistres en mode reflexion totale attenuee. Les informations spectrales ont permis de mettre en evidence les fonctions chimiques impliquees dans les mecanismes d’absorption de l’humidite et de quantifier le taux d’humidite retenu par les fibres. Pour cela, des modeles de regression partielle des moindres carres ont ete developpes en exploitant des donnees experimentales issues de mesures gravimetriques. Ces modeles se sont reveles de bons outils pour la caracterisation des cinetiques de diffusion de l’eau dans ces differentes fibres.
Do User Reviews Matter? Empirical Evidence on the Role of User Involvement in App Performance

The extant literature often presumed that user involvement was positively associated with software performance. In the context of mobile applications (apps), user reviews were collected to enlighten app developers on improvement of app quality through identifying bugs or suggesting new features. However, the value of user reviews varied a great deal due to their unmanageable volume and content irrelevance. In this study, over 40,000 user reviews with 50 apps were analyzed to empirically examine the association between customer led improvement and the revenues from the apps. Our findings indicated that customer led improvement produced significant increase in quarterly revenues. Greater growth in revenues was also observed if the developers responded to the user reviews faster. These results showed empirical support for the value of co-creation of apps with users, as customers could contribute to continuous improvement of the apps by providing experienced-based solutions.

Who Is Practicing Expedited Partner Therapy and Why? Insights From Providers Working in Specialties With High Volumes of Sexually Transmitted Infections

This qualitative study delineates specialty-specific hurdles to expedited partner therapy use among providers working in settings with high volume of sexually transmitted infections; tailored implementation strategies, particularly expedited partner therapy training, are urgently needed to improve patient/partner outcomes. Supplemental digital content is available in the text. Background Expedited partner therapy (EPT), the practice of prescribing antibiotics for sexual partners of patients, is underutilized in Georgia. This qualitative study in a large urban institution aimed to (1) characterize the clinical specialties that predominantly treat sexually transmitted infections (STIs), (2) identify perceived barriers to EPT, and (3) describe strategies to advance routine EPT use. Methods Providers in obstetrics/gynecology (OB/GYN), infectious disease (ID), and emergency medicine (EM) were interviewed using a structured discussion guide. Transcripts were double-coded and iteratively analyzed using qualitative content analysis. Barriers and strategies were summarized and supported with quotes from providers (n = 23). Results Perceived EPT barriers overlapped across OB/GYN, ID, and EM, yet the settings were diverse in their patient populations, resources, and concerns. Providers in OB/GYN were the only ones practicing EPT, yet there was a lack of standardization. Providers in ID noted that an EPT prescription from an ID provider could inadvertently disclose the HIV status of a patient to a sexual partner, posing an ethical dilemma. Providers in EM exhibited readiness for EPT, although routine empiric treatment for index patients in EM (estimated at 90%) gave some providers pause in prescribing for partners: “I do not know what I’m treating. ” Point-of-care testing could increase providers’ confidence in prescribing EPT, yet some worried it could contribute to overutilization of the emergency department as a sexually transmitted infection clinic. All settings prioritized setting-specific training and protocols. Conclusions Providers in OB/GYN, ID, and EM report unique hurdles, specific to their settings and patient populations; tailored EPT implementation strategies, particularly provider training, are urgently needed to improve patient/partner outcomes.

1Center for Reproductive Endocrinology and Infertility, Hue University of Medicine and Pharmacy, Hue University, Hue, Vietnam; 2Department of OBGYN, Hue University of Medicine and Pharmacy, Hue University, Hue, Vietnam Purpose: Metabolic syndrome (MetS) has been reported as a deleterious factor in male fertility potential, associated with hypogonadism, impaired spermatogenesis, decreased sperm concentration and motility, and increased sperm DNA damage. This study aimed to determine the prevalence of MetS in men from infertile couples and evaluate its effect on semen analysis (SA). Participants and Methods: A cross-sectional descriptive study was performed in men from infertile couples diagnosed based on the World Health Organization 2010 criteria and treated at the Hue Center for Reproductive Endocrinology and Infertility, Vietnam. General information included medical history, lifestyle, MetS factors, SA, and sperm DNA fragmentation test were collected. Based on the diagnostic criteria of the American Heart Association and the National Heart, Lung, and Blood Institute for Asian men, the study population was divided into two groups: MetS and non-MetS groups. The outcomes were analyzed for any relationship between MetS and the SA index and the DNA fragmentation index (DFI). Results: A total of 534 men from infertile couples were included in this study. The prevalence of MetS was 23.4%, and abnormal semen analysis accounted for 93.8%. Age, body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), hepatitis B and total cholesterol were related to the occurrence of MetS in infertile men (p <0.05). MetS did not reveal any impact on the parameters of SA. There was a positive correlation between waist circumference (WC), WHR, WHtR, and systolic blood pressure (BP) with abnormal sperm head and DFI (p <0.05). Conclusion: Although the prevalence of MetS was remarkable in men from infertile couples, there was no association between MetS and semen quality. However, WC, WHR, WHtR, and systolic BP were found to be significantly associated with abnormal sperm head and DFI.
The Macroeconomics of Testing and Quarantining y

We develop a SIR-based macroeconomic model to study the impact of testing/ quarantining and non-pharmaceutical interventions (NPIs) on health and economic outcomes. These policies can dramatically reduce the costs of an epidemic. Absent testing/quarantining, the main e¤ect of NPIs on health outcomes is to delay, rather than reduce, epidemic-related deaths. NPIs reduce the severity of the epidemic-related recession but prolong its duration. There is an important synergy between NPIs and testing/quarantining. NPIs buy time for PIs to come to the rescue. The bene ts of testing/quarantining are even larger when people can get reinfected, either because the virus mutates or immunity is temporary. JEL Classi cation: E1, I1, H0
Characteristics Associated with Teacher Attrition:

This study investigated possible relationships between selected teacher candidate characteristics and changes in concerns about teaching reported prior to and following teacher preparation for those candidates successfully entering or failing to enter the teaching profession. A longitudinal sample of 242 teacher candidates reported concerns about self-survival as a teacher, the task of teaching, having a positive impact upon pupils, and concerns about obtaining a teaching position prior tc and near the end of teacher preparation, and then seven years after the commencement of teacher preparation these candidates were classified as to the extent of their success in entering the teaching profession. The MANOVA procedures completed with the collected data revealed changes in concerns about teaching during preparation; no differences in teaching concerns between full-time teachers, part-time teachers, and those not teaching; and several statistical interactions. The statistical interactions revealed relationships between the candidates' degree of success in making the transition from students to teachers and the candidates' grade level of instruction, time in preparation, student teaching performance ratings, extent of initial assurance about becoming teachers, Comprehensive Test of dasic Skills scores, and Myers-Briggs personality preferences for one or more of the concerns about teaching scores.

Proﬁling and Detecting Fake News Spreaders on Social Media

: Nowadays our society is subjected to a massive spread of digital information. This spread has led to a great amount of false information, such as rumours, fake news , and extremely biased news, being shared and consumed by Internet users every day. Due to the great impact of fake news on politics, economy and health, it is becoming essential to design tools for the automatic veriﬁcation of the veracity of online information. From this point of view, this proposal aims to research about the detection and classiﬁcation of information that will help identifying internet users as fake news spreaders or reliable sources.
Using Discrete Hazard Bayesian Networks to Identify which Features are Relevant at each Time in a Survival Prediction Model

When predicting the survival time of a patient, different covariates may be important at different times. We introduce a survival prediction model, “discrete hazard Bayesian network”, that can provide individual survival curves and also identify which features are relevant for each time interval. This model encodes the discrete hazard function as a sequence of (possibly different) Bayesian networks, one for each time interval. Note each such network includes a “Death” node, which is True iff the person dies in that interval. A set of features relevant for each time interval are the nodes in the Markov blanket around that “Death” node for that interval. We also apply a “discrete hazard computation correction” based on the effective sample size – a correction that avoids biased survival curves. We first show that our model is effective by demonstrating that it can identify the time-varying relevance of the features, using the synthetic dataset. We then provide two real-world examples by analyzing the relevant features for different times on the North Alberta cancer dataset and the Norway/Stanford breast cancer dataset.
Assessment on heavy metals pollution in surface sediments of Dianchi Lake and its estuaries

In this paper,heavy metals such as As,Pb,Cd,Cr,Cu,Zn and Hg in surface sediments from Dianchi Lake and its estuaries were analyzed. Index of geo-accumulation and potential ecological risk index were utilized to assess the pollution level and potential ecological risk of heavy metals. The results showed that the highest contents of heavy metals in surface sediments were found in the north of Caohai section of Dianchi Lake. The overall intensity of heavy metals pollution in Caohai section and its estuaries was higher than that in Waihai section and its estuaries. According to Environmental quality standard for soils,As and Cd were the main pollutants in sediments. The results of index of geo-accumulation assessment showed that Cd was the main pollutant with a pollution level of severe,while other heavy metals were less than the moderate pollution level in surface sediments of Caohai section and its estuaries. However,all heavy metals were from uncontaminated to partial moderate pollution levels in Waihai section and its estuaries. The results of potential ecological risk assessment showed that the overall very high potential ecological risk was found in Caohai section and its estuaries while low risk level in Waihai section and its estuaries. The primary heavy metal pollutant with the largest contribution for the ecological risk indices( RI) was Cd,followed by Hg,As,Pb and Cu. While slight potential ecological risks were caused by Zn and Cr which had a low contribution for RI. The analysis of correlations and principal components showed that Cu,Pb,Zn,Cd,Hg and As in Dianchi Lake could have similar pollution sources,while the distribution of Cr in the lake may be mainly controlled by local geological chemical components.
A Probabilistic Model for Real-Time Semantic Prediction of Human Motion Intentions from RGBD-Data

For robots to execute their navigation tasks both fast and safely in the presence of humans, it is necessary to make predictions about the route those humans intend to follow. Within this work, a model-based method is proposed that relates human motion behavior perceived from RGBD input to the constraints imposed by the environment by considering typical human routing alternatives. Multiple hypotheses about routing options of a human towards local semantic goal locations are created and validated, including explicit collision avoidance routes. It is demonstrated, with real-time, real-life experiments, that a coarse discretization based on the semantics of the environment suffices to make a proper distinction between a person going, for example, to the left or the right on an intersection. As such, a scalable and explainable solution is presented, which is suitable for incorporation within navigation algorithms.
TESTING QCD WITH TAU DECAYS

The invariant-mass distribution of the hadronic nal state in decay can be used for testing fundamental aspects of the strong interactions. Using standard QCD techniques, it is possible to compute certain weighted integrals of the hadronic spectrum. We work out some QCD predictions which will be useful for analysing the data. They provide a direct way to simultaneously measure s(m 2 ) and the parameters characterizing the non-perturbative dynamics, allowing for a better control of the theoretical errors in the determination of s(m 2 ). *) On leave of absence from Departament de F sica Te orica, Universitat de Val encia, and IFIC, Centre Mixte Universitat de Val encia CSIC, E-46100 Burjassot (Val encia), Spain.

Early Childhood Educators’ Perspectives on Early Childhood Settings and Collaborations to Promote Kindergarten Transition

Previous research indicates that many children have difficulty transitioning from preschool to kindergarten, which may be attributed to differences between the two settings. The purpose of this study was to investigate preschool and elementary school educators’ perceptions of the similarities of and differences between the two types of settings and their perceptions of how preschool-elementary collaborations could facilitate young children’s transition to kindergarten. Sixteen early childhood educators from elementary and preschool settings were interviewed. All educators saw more differences compared to similarities between the two settings. For example, they viewed elementary school as more focused on academic domains. Educators noted that the elementary school curriculum and flow of day was generally more structured and that preschools tended to promote greater family engagement. Participants suggested that by engaging in joint activity together, these two groups of educators could learn about each other’s institutions and find ways to facilitate kindergarten transition.
Does Job Embeddedness Mediate the Effect of Resilience on Cabin Attendants’ Career Satisfaction and Creative Performance?

An increasing body of research suggests job embeddedness (JE) as a motivational variable influencing employees’ attitudinal and behavioral outcomes such as quitting intentions and task performance. Personal resources have been reported to affect JE and these outcomes. However, little work has investigated the antecedents and consequences of JE among cabin attendants. There is also a dearth of empirical research regarding the mechanism linking resilience to cabin attendants’ affective and performance outcomes. Therefore, drawing on conservation of resources and JE theories, we propose a conceptual model that examines the interrelationships of resilience, JE, career satisfaction (CSAT), and creative performance (CPERF). Moreover, the model explores JE as a mediator of the impact of resilience on CSAT and CPERF. These linkages were tested via data collected from cabin attendants and their pursers. The findings from structural equation modeling reveal that resilience boosts cabin attendants’ JE, CSAT, and CPERF. As predicted, JE is a mediator between resilience and CSAT. Our paper culminates with implications for theory and practice as well as future research directions.
Trade Unions and the Real Living Wage Final Version

A notable development in industrial relations in recent years has been the growth of civil regulation: the formation of norms, standards and codes of practice by civil society organizations (CSOs) that they seek to have adopted by employers (Williams et al. 2011). An important question that is raised by this development concerns the relationship between civil regulation and more established methods of regulating employment through trade unionism and collective bargaining. One possibility is that civil regulation can hybridize with joint regulation, serving to reinforce the institutional position of trade unions and providing them with a resource better to represent their members. A reinforcing dynamic of this kind is suggested in the literature on union revitalization, by those who argue that unions can benefit from forming coalitions with CSOs that can provide unions with additional resources, campaigning expertise, enhanced legitimacy and the ability to contact previously unorganized workers (Tattersall 2010). Coalitions might also benefit CSOs, allowing them to draw upon union resources, such as bargaining relationships with employers and political influence, to help diffuse civil regulation. A particular benefit that unions might provide to CSOs is a presence at the workplace, allowing for the monitoring and full implementation of labour standards in a manner that compensates for the lack of an ongoing workplace presence of many campaigning organizations (Heery et al. 2014; see also Harvey et al. 2017).
PPS_2100093 1..17

Pre-analysis plans (PAPs) have been championed as a solution to the problem of research credibility, but without any evidence that PAPs actually bolster the credibility of research. We analyze a representative sample of 195 PAPs registered on the Evidence in Governance and Politics (EGAP) and American Economic Association (AEA) registration platforms to assess whether PAPs registered in the early days of pre-registration (2011–2016) were sufficiently clear, precise, and comprehensive to achieve their objective of preventing “fishing” and reducing the scope for post-hoc adjustment of research hypotheses. We also analyze a subset of ninety-three PAPs from projects that resulted in publicly available papers to ascertain how faithfully they adhere to their preregistered specifications and hypotheses. We find significant variation in the extent to which PAPs registered during this period accomplished the goals they were designed to achieve. We discuss these findings in light of both the costs and benefits of preregistration, showing how our results speak to the various arguments that have been made in support of and against PAPs. We also highlight the norms and institutions that will need to be strengthened to augment the power of PAPs to improve research credibility and to create incentives for researchers to invest in both producing and policing them.
EFFECT OF ENRICHED COMPOSTS AND DIFFERENT LEVELS OF N-P-K FERTILIZERS ON PLANT HEIGHT AND DRY MATTER PRODUCTION OF SUNFLOWER GROWN IN SANDY CLAY LOAM SOIL

The present investigation comprises a pot experiment on sunflower cv. Sunbred was carried out to study the effect of different levels of chemical fertilizers and different enriched organic composts. It was conducted during April-July, 2017 at the pot culture yard of Department of Soil Science & Agricultural Chemistry, Faculty of Agriculture, Annamalai University, Annamalainagar. The initial soil of the pot experiment was sandy clay loam in texture with a pH of 7.4 and EC of 0.44 dSm. A pot experiment was conducted with the treatments of five levels of factor-A (EC0–Control, EC1 – EFYM, EC2 – EWHC, EC3 – ENLC, EC4–ESDC ). and four levels of factor-B (CF0–Control, CF1–75% RDF, CF2–100% RDF, CF3–125% RDF) (20 treatment combinations), laid out in factorial completely randomized design (FCRD) with three replications. Recommended dose of N:P2O5:K2O for sunflower is 60:90:60 kg ha -1 respectively were applied in the form of urea, SSP and MOP, respectively. Sunflower cv. Sunbred was grown as a test crop. The results revealed that application of enriched composts and different levels of chemical fertilizers significantly increased the plant height and dry matter production of sunflower at 30, 60 and at harvest stages of sunflower. Among the different treatments, the combined application of CF3–125% RDF + enriched water hyacinth compost (EWHC) recorded the highest plant height 149.40 cm and dry matter production of 99.82 g pot at harvest stage of sunflower.
