ASSESSING MERCURY POLLUTION USING BLACK STORK EGGSHELLS
2021
Female birds whose bodies contain environmental contaminants produce eggs with shells that are likewise contaminated, making bird eggshells appropriate indicators for monitoring environmental toxins. Common contaminants include organic mercury compounds, especially methylmercury, which are known to bioaccumulate and biomagnify in the food chain. Black storks (Ciconia nigra) predominantly consume fish and are thus at risk for high mercury intake. In this study, we used eggshells of black storks as a proxy to reconstruct the concentration levels and distribution of mercury, a well-known toxic element, in various parts of Latvia. Preliminary analyses have shown that deposition levels of mercur…

Human Resource Management rules and practices in the health sector : Why do disconnected forms of social regulation persist ?
2021
International audience; This systematic review of the academic literature since 1994 on the application of HRM rules in health care sheds light on the persistence of gaps between institutional norms and standards related to human resource management (HRM) procedures and the actual practices in organizations. Contrary to the affirmation of Scandinavian institutionalism, “translation” processes do not eliminate “controversies”, nor put an end to “decoupling”. The very grounds of new public management (NPM) are brought under question. Though not well known among English-speaking academics, Reynaud’s theory of social regulation opens the way toward explaining this phenomenon and challenges neoi…

Fibromyalgia severity according to age categories: results of a cross-sectional study from a large national database
2021
ObjectiveThe role of age in influencing the severity of fibromyalgia (FM) is still controversial. The aim of this study is to define the contribution of age in the severity of FM from data from a large national database.MethodsThis cross-sectional study included adult patients with FM diagnosed according to the 2010/2011 American College of Rheumatology criteria. Disease severity was assessed with the revised Fibromyalgia Impact Questionnaire (FIQR) and the modified Fibromyalgia Assessment Status (FAS 2019mod). Patients were grouped into five age categories (between 18-40 years, between 41- 50 years, between 51-60 years, between 61-70 years, and =71 years). Differences in disease severity b…
Inhomogeneous Broadening of Photoluminescence Spectra and Kinetics of Nanometer-Thick (Phenethylammonium)2PbI4 Perovskite Thin Films: Implications fo…
2021
An outstanding potentiality of layered two-dimensional (2D) organic–inorganic hybrid perovskites (2DHPs) is in the development of solar cells, photodetectors, and light-emitting diodes. In 2DHPs, an exciton is localized in an atomically thin lead(II) halide inorganic layer of sub-nanometer thickness as in a quantum well sandwiched between organic layers as energetic and dielectric barriers. In previous years, versatile optical characterization of 2DHPs has been carried out mainly for thin flakes of single crystals and ultrathin (of the order of 20 nm) polycrystalline films, whereas there is a lack of optical characterization of thick (hundreds of nanometers) polycrystalline films, fundament…
Prognostic value of NT-proBNP and CA125 across glomerular filtration rate categories in acute heart failure.
2021
This study aimed to evaluate whether glomerular filtration rate (eGFR) during admission modifies the predictive value of plasma amino-terminal pro-brain natriuretic peptide (NT-proBNP) and carbohydrate antigen 125 (CA125) in patients hospitalized for acute heart failure (AHF).We retrospectively evaluated 4595 patients consecutively discharged after admission for AHF at three tertiary-care hospitals from January 2008 through October 2019.

Toward a Theoretical Framework of Corporate Social Irresponsibility: Clarifying the Gray Zones Between Responsibility and Irresponsibility
2021
In this conceptual article, we argue that defining corporate social responsibility (CSR) and corporate social irresponsibility (CSI) as opposite constructs produces a lack of clarity between responsible and irresponsible acts. Furthermore, we contend that the treatment of the CSR and CSI concepts as opposites de-emphasizes the value of CSI as a stand-alone construct. Thus, we reorient the CSI discussion to include multiple aspects that current conceptualizations have not adequately accommodated. We provide an in-depth exploration of how researchers define CSI and both identify and analyze three important gray zones between CSR and CSI: (a) the role of harm and benefit, (b) the role of the a…
Does clinically relevant psychopathology in adolescents necessarily require treatment or does it “grow out”?
2021
OBJECTIVE: To determine the treatment effect of psychodynamic therapy for adolescents in comparison to normative developmental progression in two groups without treatment: healthy adolescents and adolescents with juvenile diabetes. RESEARCH DESIGN AND METHODS: In a 3-wave longitudinal study, n = 531 adolescents (n = 303 treated adolescents, n = 119 healthy, n = 109 with diabetes) and their parents filled out psychopathology questionnaires (Youth Self-Report [YSR] and Child Behaviour Checklist [CBCL]).

Climate change is having a serious impact on many ecosystems. In the summer of 2018 and 2019, around two thirds of European beech trees were damaged or killed by extreme drought. It is critical to keep these beech woods healthy, as they are central to the survival of over 6,000 other species of animals and plants. The level of damage caused by the drought varied between forests. However, not all the trees in each forest responded in the same way, with severely damaged trees often sitting next to fully healthy ones. This suggests that the genetic make-up of each tree determines how well it can adapt to drought rather than its local environment. To investigate this further, Pfenninger et al. …

In addition, we outline some needs for future research in order to gain new perspectives for future studies.
A Method Based on Amplitude Probability Density Representation for Sounding High Frequency Noise in Ionospheric Channels
2021
High Frequency (HF) communications efficiency require a precise characterization of the ionospheric channel’s noise. We present a rapid and accurate method to sound the HF ionospheric channels that enables tracing of the time-availability of the channel based on imposed electric field strength thresholds. The method makes use of the amplitude probability density implemented in a real-time spectrum analyzer. Sounding of 3, 10 and 20 kHz bandwidth channels in the 4.8 – 8.8 MHz range is exemplified and specific observations are presented.

CENTRAL LIMIT THEOREM FOR KERNEL ESTIMATOR OF INVARIANT DENSITY IN BIFURCATING MARKOV CHAINS MODELS
2021
Bifurcating Markov chains (BMC) are Markov chains indexed by a full binary tree representing the evolution of a trait along a population where each individual has two children. Motivated by the functional estimation of the density of the invariant probability measure which appears as the asymptotic distribution of the trait, we prove the consistence and the Gaussian fluctuations for a kernel estimator of this density based on late generations. In this setting, it is interesting to note that the distinction of the three regimes on the ergodic rate identified in a previous work (for fluctuations of average over large generations) disappears. This result is a first step to go beyond the thresh…

Forever Young: Structural Stability of Telomeric Guanine Quadruplexes in the Presence of Oxidative DNA Lesions**
2021
International audience; Human telomeric DNA, in G-quadruplex (G4) conformation, is characterized by a remarkable structural stability that confers it the capacity to resist to oxidative stress producing one or even clustered 8-oxoguanine (8oxoG) lesions. We present a combined experimental/computational investigation, by using circular dichroism in aqueous solutions, cellular immunofluorescence assays and molecular dynamics simulations, that identifies the crucial role of the stability of G4s to oxidative lesions, related also to their biological role as inhibitors of telomerase, an enzyme overexpressed in most cancers associated to oxidative stress.

2021
Aim Arrhythmogenic cardiomyopathy (ACM) is a primary myocardial disease that typically manifests with cardiac arrhythmias, progressive heart failure and sudden cardiac death (SCD). ACM is mainly caused by mutations in genes encoding desmosome proteins. Desmosomes are cell-cell adhesion structures and hubs for mechanosensing and mechanotransduction. The objective was to identify the dysregulated molecular and biological pathways in human ACM in the absence of overt heart failure. Methods and results Transcriptomes in the right ventricular endomyocardial biopsy samples from three independent individuals carrying truncating mutations in the DSP gene and 5 control samples were analyzed by RNA-S…

Työn tuunaamisen profiilit sosiaali- ja terveysalan organisaatiossa : yhteydet työhyvinvointiin
2021
Työn tuunaaminen on oma-aloitteista työn kehittämistä työn voimavaroja ja vaatimuksia muokkaamalla. Tutkimme, millaisia tuunausprofiileja voidaan löytää kolmesta erilaisesta tuunaustavasta, jotka olivat työn voimavarojen lisääminen, työn vaatimusten lisääminen ja työn vaatimusten optimoiminen. Selvitimme myös, miten työhyvinvointi vaihtelee profiileissa. Sähköiseen kyselyyn osallistui 1 024 sosiaali- ja terveysalan organisaation työntekijää. K-keskiarvojen klusterianalyysin avulla tunnistimme neljä työn tuunaamisen profiilia: aktiiviset tuunaajat (19 %, monipuolinen tuunaaminen), optimoivat tuunaajat (21 %, työn vaatimusten optimointi), passiiviset tuunaajat (27 %, keskimääräistä vähemmän t…

El Gran rescate de la prensa española: los anticipos reintegrables durante la Primera Guerra Mundial
2021
Resumen La crisis económica que se derivó de la Primera Guerra Mundial provocó, entre otros efectos, la caída aguda de los resultados económicos de la prensa española y una amenaza real de colapso generalizado. Reconvertida a grandes empresas, con exponentes como el primer trust periodístico español, creado en 1906, los editores de periódicos plantearon por primera vez un dilema clave para el sistema representativo: si se quería que existiese prensa, el tesoro público debía colaborar mediante subvenciones a la compra de papel. Se puso en marcha, de esta forma, el primer gran rescate de la prensa española, con una aportación millonaria de dinero público a empresas privadas que, en teoría, te…
Bimanual robot control for surface treatment tasks
2021
This work develops a method to perform surface treatment tasks using a bimanual robotic system, i.e. two robot arms cooperatively performing the task. In particular, one robot arm holds the workpiece while the other robot arm has the treatment tool attached to its end-effector. Moreover, the human user teleoperates all the six coordinates of the former robot arm and two coordinates of the latter robot arm, i.e. the teleoperator can move the treatment tool on the plane given by the workpiece surface. Furthermore, a force sensor attached to the treatment tool is used to automatically attain the desired pressure between the tool and the workpiece and to automatically keep the tool orientation …
Jaws Vs. Blue ocean » : créer un « océan bleu » pour contrer la « crise requin » à l’île de La Réunion

International audience; Cet article mobilise un cadre d’analyse fondé sur la théorie des ressources et compétences et la notion d’innovation stratégique. L’innovation est présente dans la littérature portant sur le management touristique, mais elle apparait très rarement sous l’aspect de l’innovation stratégique (Hjalager, 2010) et n’est pas mobilisée dans un contexte de management de crise. Nous nous fondons sur la théorie des ressources pour proposer l’application d’une optique d’exploration et d’innovation stratégique en tant que réponse à une situation de crise dans le secteur touristique. L’analyse repose sur la technique de l’étude de cas (Stake, 1994) au travers d’interviews et de l’…

European children and adolescents spend most of their daily life and especially their school hours being sedentary which may increase their risk for chronic non-communicable diseases later in life. After the curriculum reform of Finnish basic education in 2014, most of the new or renovated comprehensive schools in Finland incorporate open and flexible classroom designs. Their open learning spaces may provide students opportunities to reduce sedentary behavior during school hours. Thus, waist-worn accelerometers were used to assess classroom-based sedentary time (ST), the number of breaks from sedentary time (BST), and physical activity (PA) among cross-sectional samples of 3rd and 5th grade…
