This paper is the second part of a new geohazards analysis applied to a large part of the Tien Shan, Central Asia, focused on landslide susceptibility computations that are based on recently compiled geographic, geological and geomorphological data. The core data are a digital elevation model, an updated earthquake catalogue, an active fault map as well as a new landslide inventory. The most recently added digital data are a new simplified geological map, an annual precipitation map, as well as river and road network maps that were produced for the Kyrgyz and Tajik parts of the Tien Shan. On the basis of these records we determine landslide densities with respect to morphological (M), geological (G), river distance (R), precipitation (P), earthquake (E) and fault (F) distance factors. Correlations were also established between scarp locations and the slope angle, distance to rivers, curvature. These correlations show that scarps tend to be located on steeper slopes, farther from rivers and on more convex terrain than the entire landslides. On the basis of the landslide density values computed for each class of the aforementioned factors, two landslide susceptibility maps are created according to the Landslide Factor analysis: ...

Capgras delusion is characterized by the misidentification of people and by the delusional belief that the misidentified persons have been replaced by impostors, generally perceived as persecutors. Since little is known regarding the neural correlates of Capgras syndrome, the cerebral metabolic pattern of a patient with probable Alzheimer’s disease (AD) and Capgras syndrome was compared with those of 24 healthy elderly subjects and 26 AD patients without delusional syndrome. Compared to the healthy and AD groups, the patient had significant hypometabolism in frontal and posterior midline structures. In light of current neural models of face perception, our patient’s Capgras syndrome may be related to impaired recognition of a familiar face, subserved by the posterior cingulate/precuneus cortex, and impaired reflection about personally relevant knowledge related to a face, subserved by the dorsomedial prefrontal cortex.

The Childhood Executive Functioning Inventory (CHEXI) is a new rating instrument for executive functioning developed by Thorell and Nyberg (2008). Through exploratory factor analyses, this inventory has been shown to tap into working memory and inhibition-related behaviors in young children. In this study, we present the psychometric characteristics of the French adaptation of the CHEXI in 8- to 11-year-old children. In addition, we explore the cross-cultural validity of the CHEXI in discriminating between children with ADHD and normally developing children in two culturally different samples (Belgian and Swedish). Confirmatory factor analyses replicated the two-factor solution, referred to as inhibition and working memory, that was identified in the original study with Swedish children. Supplementary analyses indicated that both subscales have good psychometric properties. From a clinical point of view, the CHEXI was found to discriminate, with high sensitivity and specificity, between children with ADHD and normally developing controls in both cultural samples. Cross-cultural clinical implications are discussed. [less ▲]

Customers often experience intense emotions during service encounters. Their perceptions of how well contact employees demonstrate emotional competence in emotionally charged service encounters can affect their service evaluations and loyalty intentions. Previous studies examining employees’ potential to behave in emotionally competent ways (i.e., employee emotional intelligence [EEI]) have used self- or supervisor-reported scales to predict customer outcomes, presenting EEI as stable and independent of the context. However, service firms should be more concerned with the actual display of emotionally competent behaviors by employees (employee emotional competence [EEC]), because employee behaviors vary across encounters. Moreover, a customer perspective of EEC is useful as customer perceptions of employee performance are crucial predictors of satisfaction and loyalty. Therefore, this study proposes a conceptualization and operationalization of EEC in a service encounter context. On the basis of a comprehensive literature review and in-depth interviews, the authors develop a scale to capture customer-perceived EEC, defined as an employee’s competence in perceiving, understanding, and regulating customer emotions during a discrete service encounter. The scale achieves good reliability and validity. Researchers can use it to explore the role of EEC in service contexts; managers can employ the scale to diagnose EEC and improve customers’ service encounter experiences. [less ▲]

It is usual to think of the spectacular development of the Brentano School in Austria as being tied to the rise of a specific research program, which is sometimes dubbed “Austrian phenomenology”. I discuss here some evidences for the existence of such a program. In the discussion, I highlight two claims which I take to be constitutive of the Brentanian phenomenology. The first one is the epistemological claim according to which our concepts all have an empirical origin, which has to be located in the experience we have of our own mental states. The second one is the methodological claim according to which describing a mental phenomenon P is nothing but analysing P, where “analysing P” simply means “distinctly perceiving all the constituents of P”. Although a deeper insight in those two claims would require considerable further investigations, I suggest they should be part of the picture when it comes to adjudicating on the specificity of the Brentanian program.

The Treynor and Mazuy framework is a widely used return-based model of market timing. However, existing corrections to the regression intercept can be manipulated through derivatives trading. We propose an adjustment based on Merton's option replication approach. The linear and quadratic coefficients of the regression are exploited to assess the cost of the replicating option that yields similar convexity for a passive portfolio. A similar reasoning applies for various timing patterns and in multi-factor models. The proposed framework induces a potential rebalancing risk and involves the delicate issue of choosing the cheapest option. We show that these issues can be overcome for reasonable tolerance levels.

To date, magnetic shields utilizing high-temperature superconductor materials mostly comprise bulk materials, usually shaped into a cylinder and then heat treated. We analyze the potential of thin-film technology, whereby a layer of superconductor is deposited on a substrate, to fabricate magnetic shields. Films deposited on a curved surface are inevitably granular, leading to reduced critical current density compared with crystalline films. This limits the maximum field that can be screened. Granular films also have an enhanced penetration depth compared with the bulk value, which determines the maximum possible screening at applied fields below the maximum.We demonstrate the utility of a mutual inductancemeasurement to evaluate small flat test samples of a granular film for their potential as a shielding material in a more complex geometry. Thismeasurement predicts both themaximum magnetic field that can be screened and the residual leakage at fields below the maximum. The tested film was produced by the Electrophoretic deposition of YBCO on a silver substrate. The maximum screening field was comparable with that obtained for a similar film on a cylindrical substrate. We also show comparable results from a crystalline YBCO film. [less ▲]

INTRODUCTION: Cardiopathies are the world's leading cause of mortality and morbidity. Although rare, cardiovascular accidents can occur during intense and infrequent sporting activity, particularly among those who are unaware of their heart condition. The development of cardiospecific biochemical markers has led to a reconsideration of the role of biology in the diagnosis of cardiovascular illnesses. The aim of this study therefore was, through the use of cardiac biomarker assays, to highlight the impact of sustained physical effort in the form of intense and prolonged concentric isokinetic exercise and to research potential cardiovascular risks. MATERIALS AND METHODS: Eighteen subjects participated in a maximal concentric isokinetic exercise involving 30 knee flexion-extensions for each leg. Five blood tests were taken to study the kinetics of the cardiac biomarkers. Haemodynamic parameters were measured continuously using a Portapres, and respiratory parameters were measured using a Sensormedics Vmax 29C. RESULTS: The results showed significant increases in the creatine kinase, myoglobin, homocysteine and haemoglobin cardiac markers. Evolutionary trends were also observed for the following biomarkers: NT-proBNP, myeloperoxydase and C-reactive protein. All the physiological parameters measured presented statistically significant changes. CONCLUSION: Isokinetic effort leads to the release of cardiac markers in the blood, but these do not exceed the reference values in healthy subjects. Maximal concentric isokinetic exercise does not, therefore, lead to an increased risk of cardiovascular pathologies. [less ▲]

La période fin de siècle s’accompagne, dans le champ littéraire français, du développement d’une série de groupuscules plus ou moins organisés et volontiers potaches. Au cœur de ces associations liées de près ou de loin à ce qu’Ernest Raynaud qualifiera de « mêlée symboliste » (1920-1922), le rire fonctionne comme un véritable ciment social, renforçant les liens des membres de la collectivité et redoublant l’exclusion de ceux qui n’en sont pas. Héritiers d’entreprises collectives comme Le Parnassiculet contemporain (1866) et l’Album zutique (composé en 1871 et tenu délibérément à l’écart des circuits de diffusion du livre), les agents engageant les projets des Hydropathes, des Hirsutes, des Jemenfoutistes ou de l’incontournable cabaret du Chat Noir se rassemblent non seulement dans une perspective dérisoire, mais encore se dotent-ils d’un discours qui, plus qu’un simple divertissement, présente cette dérision comme principe régulant l’activité collective. Ce sont, à l’aune des cas susmentionnés, quelques-uns de ces discours du rire collectif fin de siècle que nous explorons ici, en nous penchant sur les mécanismes rhétoriques qui les fondent et sur les grandes logiques (d’opposition à des figures spécifiques ou à des institutions) qui les motivent, en cherchant à mettre en lumière la façon dont cette omniprésence de la dérision est directement provoquée par l’état du champ littéraire de l’époque.

Purified chitin-glucan complex (CGCpure) was extracted from Komagataella pastoris biomass using a hot alkaline treatment, followed by neutralization and repeated washing with deionised water. The co-polymer thus obtained had a glucan:chitin molar ratio of 75:25 and low protein and inorganic salts contents (3.0 and 0.9 wt%, respectively). CGCpure had an average molecular weight of 4.9 × 105 Da with a polydispersity index of 1.7, and a crystallinity index of 50%. Solid-state NMR provided structural insight at the co-polymer. X-ray diffraction and FTIR analysis suggest that CGCpure has b-chitin in its structure. CGCpure presented an endothermic decomposition peak at 315 oC, assigned to the degradation of the saccharide structures. This study revealed that K. pastoris CGC has properties similar to other chitinous biopolymers and may represent an attractive alternative to crustacean chitin derived-products, being a reliable raw material for the development of new/improved pharmaceutical, cosmetic or food products.

The toxicity of methylmercury (MeHg) in humans is well established and the main source of exposure is via the consumption of large marine fish and mammals. Of particular concern are the potential neurodevelopmental effects of early life exposure to low-​levels of MeHg. Therefore, it is important that pregnant women, children and women of childbearing age are, as far as possible, protected from MeHg exposure. Within the European project DEMOCOPHES, we have analyzed mercury (Hg) in hair in 1799 mother-​child pairs from 17 European countries using a strictly harmonized protocol for mercury anal. Parallel, harmonized questionnaires on dietary habits provided information on consumption patterns of fish and marine products. After hierarchical cluster anal. of consumption habits of the mother-​child pairs, the DEMOCOPHES cohort can be classified into two branches of approx. similar size: one with high fish consumption (H) and another with low consumption (L)​. All countries have representatives in both branches, but Belgium, Denmark, Spain, Portugal and Sweden have twice as many or more mother-​child pairs in H than in L. For Switzerland, Czech Republic, Hungary, Poland, Romania, Slovenia and Slovakia the situation is the opposite, with more representatives in L than H. There is a strong correlation (r=0.72) in hair mercury concn. between the mother and child in the same family, which indicates that they have a similar exposure situation. The clustering of mother-​child pairs on basis of their fish consumption revealed some interesting patterns. One is that for the same sea fish consumption, other food items of marine origin, like seafood products or shellfish contribute significantly to the mercury levels in hair. We conclude that addnl. studies are needed to assess and quantify exposure to mercury from seafood products, in particular. The cluster anal. also showed that 95​% of mothers who consume once per wk fish only, and no other marine products, have mercury levels 0.55 μg​/g. Thus, the 95th percentile of the distribution in this group is only around half the US-​EPA recommended threshold of 1 μg​/g mercury in hair. Consumption of freshwater fish played a minor role in contributing to mercury exposure in the studied cohort. The DEMOCOPHES data shows that there are significant differences in MeHg exposure across the EU and that exposure is highly correlated with consumption of fish and marine products. Fish and marine products are key components of a healthy human diet and are important both traditionally and culturally in many parts of Europe. Therefore, the communication of the potential risks of mercury exposure needs to be carefully balanced to take into account traditional and cultural values as well as the potential health benefits from fish consumption. European harmonized human biomonitoring programs provide an addnl. dimension to national HMB programs and can assist national authorities to tailor mitigation and adaptation strategies (dietary advice, risk communication, etc.) to their country's specific requirements.

Objective: The objective of this paper is to propose, starting from the description of a clinical emblematic case, a theoretical synthesis of the work of phenomenological psychopathology dedicated to melancholia and typus melancholicus (TM), a clinical concept that describes the premorbid personality vulnerable to major depression (“melancholia” for the psychopathological tradition). Method: This is phenomenological analysis of a case study of melancolia, of its premorbid personality and pathogenic triggering situation. We adopt two main phenomenological keys to understanding the develpment of melancholia : role-identity theory and desynchronization theory. The former understands melancholia as a disorder of identity triggered by the loss of the social role with which one has previously over-identifed. The latter sees melancholia as the effect of the desynchronisation from the social environment that further develops into an inhibition of the conative–affective dynamics of life. We present the case of Jonas (64 years old), whose mother (94 years old) recently died. Before his mother’s death, Jonas’ life was entirely orchestrated by the caring for his mother and synchronized in time with this (e.g., he used to go to her house every 4 hours, took all his meals with her, etc.). Jonas, in addition to being hyper-synchronized and hyper-syntonic, fulfills all diagnostic criteria for TM, including “orderliness”, “conscientiousness”, “hyper/heteronomia” and “intolerance of ambiguity”. TM’s attach a disproportioned importance to their social roles (or external representations of identity) at the expense of their own ego-identity. Results: The passage from pre-morbid personality to melancholia is triggered by the death of Jonas’ mother that entails a profound depersonalization. Desynchronization and role loss cause Jonas fall into this severe depersonalization, whose core feature is the feeling of the loss of feeling. Conclusions: This original contribution demonstrates a clinical case can contribute to the construction and refinement of theoretical and conceptual frameworks (like princeps Tellenbach's studies). Over-synchronized tempo and over-identification with social role are emblematically in this case the two sides of the same coin. A parallelism can be established between synchronization (with the mother) and respect for the role at the expense of own identity. The clinical case of Jonas highlights a conceptual bridge between the model of melancholia as loss of social role and the model of melancholia as desynchronization. [less ▲]

One of the key steps in the procedure before the Extraordinary Chambers in the Courts of Cambodia (ECCC) is the filing of a closing order in relation to one or several suspects. In case 002, Nuon Chea, Ieng Sary, Ieng Thirith and Khieu Samphan all filed motions of appeal against several aspects of the closing order delivered on 16 September 2010, by which the Co-Investigating Judges ordered their indictment. This commentary attempts to shed some light on three decisions issued by the Pre-Trial Chamber on these appeals. Two procedural matters discussed in the decisions are first outlined, namely the right to appeal against a closing order and the latter’s impact on the regime of provisional detention. The analysis then turns to the core substantive contribution of the decisions, that is, the adjudication of the various jurisdictional challenges on the basis of the nullum crimen principle. In the end, it is submitted that, on the whole, the judges showed strict adherence to the principle of legality, thereby strengthening the ECCC’s legitimacy in the realm of global criminal justice.

Of all the royal families of ancient or modern fame, few are as iconic as the eighteenth dynasty of pharaohs of the New Kingdom of Egypt, whose opulence and deeds we are still familiar to nearly 3,500 years after their time. Tenth pharaoh of this dynasty and father of Tutankhamun, Akhenaten (Amenhotep/Amenhotep IV) still fascinates Egyptologists and history lovers through the many questions surrounding his atypical rule. One of the most striking aspects of the so-called Amarna period concerns the representations of the pharaoh himself, very confusing compared to the traditional iconography of the New Kingdom. These intriguing portraits of Pharaoh raised a whole lot of medical assumptions, more or less substantiated. We review here the main theories developed throughout history. [less ▲]

In the last three decades, the development of the artisanal and small-scale mining (ASM) sector has been increasing in the Democratic Republic of Congo (DRC), bringing more and more urban families into this flourishing business sector, and among them, children. At first glance, one could see children in the mining sector mainly as victims entangled in the flows of raw materials of unbridled capitalism. But this paper aims to look at the often unconceivable, and as a result neglected, social agency of children even when they are involved in stigmatized and prohibited types of child labour. To do so, it relies on the results of a socio-anthropological collective research project on children’s mining activities which was carried out in a small locality called La Ruashi in the city of Lubumbashi (Province of Katanga). The article aims to provide a more comprehensive understanding of what is often normatively only labelled as ‘child labour’ by looking at different spheres of social relations within which children are embedded. Examining the set of social interactions that children have with their families, the broader community and their ‘peers’, several ‘family portraits’ are offered, highlighting a heterogeneity of social interpretations regarding this ‘new’ form of child work. It will be shown that for families from middle-class background, this kind of work is often socially disruptive, at the forefront of inter-generational conflict. As for families from lower classes, social changes induced by children’s mining activities are often better incorporated into the family habitus. Common social changes encountered in all families irrespective of class belonging will also be portrayed, showing the transversal societal impact these ‘new’ forms of child economic activities can provoke at a micro level.

In this double blind, unicentre, randomized, placebo controlled study, we evaluated the changes in 25-hydroxyvitamin D (25(OH)D) serum levels in 150 young Belgian adults (18–30 years), monthly supplemented with 50,000 IU of vitamin D (VTD) or placebo for 6 months, from November 2010 to May 2011. At T0, 30% of the population presented 25(OH)D serum levels below 20 ng/mL. In the VTD-treated group, mean serum levels increased from 21.2 ± 8.2 to 30.6 ± 8.8 ng/mL (𝑃 < 0.001) at T3mo and to 36.0 ± 9.2 ng/mL (𝑃 < 0.001) at T6mo. Despite documented VTD intake, no changes in serum levels were, however, observed in 10% of the treated group. In the placebo group, mean 25(OH)D serum levels decreased from22.8 ± 8.5 to 14.0 ± 6.9 ng/mL at T3mo (𝑃 < 0.001) but returned to values not significantly different from those observed at T0 (23.5 ± 8.6 ng/mL) at T6mo. No difference between serum calcium levels was observed between the groups throughout the study. In conclusion, monthly supplementation with50,000UIofVTDinwinter canwarrant serum25(OH)Dlevels above 20ng/mL in96.2%of thosehealthy young adultswithout inducing unacceptably high 25(OH)D concentration.

AIMS: The objective assessment of maximal exercise capacity (MEC) using peak oxygen consumption (VO2) measurement may be helpful in the management of asymptomatic aortic stenosis (AS) patients. However, the relationship between left ventricular (LV) function and MEC has been relatively unexplored. We aimed to identify which echocardiographic parameters of LV systolic function can predict MEC in asymptomatic AS. METHODS AND RESULTS: Asymptomatic patients with moderate to severe AS (n = 44, aortic valve area <1.5 cm2, 66 ± 13 years, 75% of men) and preserved LV ejection fraction (LVEF > 50%) were prospectively referred for resting echocardiography and cardiopulmonary exercise test. LV longitudinal strain (LS) of each myocardial segment was measured by speckle tracking echocardiography (STE) from the apical (aLS) 4-, 2-, and 3-chamber views. An average value of the LS of the analysable segments was provided for each myocardial region: basal (bLS), mid (mLS), and aLS. LV circumferential and radial strains were measured from short-axis views. Peak VO2 was 20.1 ± 5.8 mL/kg/min (median 20.7 mL/kg/min; range 7.2-32.3 mL/kg/min). According to the median of peak VO2, patients with reduced MEC were significantly older (P < 0.001) and more frequently females (P = 0.05). There were significant correlations between peak VO2 and age (r = -0.44), LV end-diastolic volume (r = 0.35), LV stroke volume (r = 0.37), indexed stroke volume (r = 0.32), and E/e' ratio (r = -0.37, all P < 0.04). Parameters of AS severity and LVEF did not correlate with peak VO2 (P = NS for all). Among LV deformation parameters, bLS and mLS were significantly associated with peakVO2 (r = 0.43, P = 0.005, and r = 0.32, P = 0.04, respectively). With multivariable analysis, female gender (β = 4.9; P = 0.008) and bLS (β = 0.50; P = 0.03) were the only independent determinants (r2 = 0.423) of peak VO2. CONCLUSION: In asymptomatic AS, impaired LV myocardial longitudinal function determines reduced MEC. Basal LS was the only parameter of LV regional function independently associated with MEC.

Populations considered for shoulder analysis are often composed of various ratios of men and women. It is consequently hypothesized that gender has no significant effect on the joint kinematic. However the literature reports, for the shoulder, differences in the range of motion between genders. The specific influence of gender on the scapula-thoracic kinematics has not been studied yet. The dominant shoulder of two populations of men and women composed of 11 subjects each were evaluated in three dimensions for three distinct motions: flexion in the sagittal plane, abduction in the frontal plane and gleno-humeral internal/external rotation with the arm abducted at 90°. Posture, kinematics and range of motion were studied separately. For flexion and abduction and with regard to the scapular kinematic, external rotation were significantly larger for women than men. The differences were of at least 5° at 120° of humeral elevation. Upward rotations were identical. Women also showed larger average active humero-thoracic range of motion. The mean differences were of 13°, 7°, 12° and 5° for abduction, flexion, internal rotation and external rotation, respectively. No difference was observed between the scapular resting positions of both populations. The observed differences concerning both the scapular and humeral patterns would indicate that the shoulder behavior of men and women should not be expected to be similar. [less ▲]

It does so by focusing on a Nigerian couple’s (attempted) itinerary of return migration from Italy to Nigeria, and on the role played by a specific transport technology, the shipping container, within this process. It highlights how, throughout the itinerary that brings the container from Italy to Nigeria, its social meaning and value become the center of a series of tense interactions, in which different conceptions of family hierarchies, contrasting spiritual beliefs, as well as diverging imaginaries about transnational mobility, migration and life abroad come to the fore, and provoke radical transformations in the life of the people involved in the itinerary of the container itself [less ▲]

The submarine part of the North Anatolian Fault (NAF) in the Marmara Sea is a significant hazard for the city of Istanbul (Turkey). The use of paleoseismological data to provide an accurate seismic risk assessment for the area is constrained by the fact that the NAF system is submarine near Istanbul; thus a history of paleoearthquakes can be inferred only by using sediment cores. Here a record of turbidites was obtained in two cores and used to reconstruct the earthquake history along a main branch of the NAF, the Cinarcik Segment. Kullenberg core Klg04 (4 m long) was collected during Marmarascarps mission from a berm north of the fault and a second core (Klg03, 3.5 m long) was positioned in the Cinarcik Basin, 3 km south of the fault. Sedimentary sequences in the two cores were correlated using variations in Ca/Ti ratio, which reflect the local aquatic productivity compared with more terrigenous input. The turbidites between the two cores were then classified to distinguish the synchronous ones from the other ones. Radionuclide measurements suggest that the most recent turbidite recorded in both cores was triggered by the M=7.3 1894 earthquake. We conclude that the turbidites are earthquake-generated, based on: 1) their distinctive sedimentological and geochemical signatures, previously described and applied in the Marmara Sea; 2) the correlation of turbidites between cores at berm and basin sites; 3) the match of the most recent turbidites with a 19th century historical earthquake; and 4) the elimination of others processes. Because of its specific geomorphological location, core Klg04 likely records only mass wasting events related to the rupture on the Cinarcik Segment. To date older turbidites, we used 14C and paleomagnetic data to build an OxCal age model with a local reservoir correction (ΔR) of 400±50 yr. The Cinarcik Segment is found to have ruptured in AD1894, AD1509, sometime in the 14th century, AD989, AD740 and in the 5th century and have a mean recurrence interval of rupture between 243 and 396 years. Following the age model obtained we finally used the earthquake record history of the Cinarcik Segment to infer the rupture history of adjacent segments of the North Anatolian Fault during six earthquake cycles over the past 1500 years.

Although a great number of studies has already been devoted to the topic of sacred trees in Greco-Roman Egypt, this paper aims at offering a new contribution to this debate by shifting the focus of research from the hitherto dominant interest in ancient and modern botanical classifications to the study of the socio-cultural contexts (and their diachronic changes) in which sacred trees were used in Hellenistic and Roman Egypt. The analysis focuses on the case study of the tree called περσ(ε)ία / persea in Greek and Latin sources. After drawing attention to the non-complete overlap between the denomination adopted by Greek and Latin authors for this Egyptian sacred plant and its “emic” Hieroglyphic / Demotic correspondents, ἰšd and šw3b, the focus will be on patterns of continuity, innovation and re-contextualization of Egyptian religious traditions in Ptolemaic and Roman Egypt and on the social actors and contexts that were involved in the use and protection of sacred plants. When approached from this perspective, the evidence on persea provides a fruitful dossier to investigate some aspects of the dialectic between continuity and transformation in cultural traditions, with particular regard to cases where traditions were adapted beyond cultural and ethnic limits. Moreover, the persea dossier enables us to discuss ancient contexts in which, for religious reasons, nature was seen as worth of being protected and preserved against the risk of extinction. This will allow us to raise some preliminary questions concerning the limits of applicability of modern environmental thinking to ancient cultures, in contexts in which the preservation of vegetal species was seen as an important value for the identity of a community, thus requiring individual and institutional commitment.

The binomial coefficient of two words $u$ and $v$ is the number of times $v$ occurs as a subsequence of $u$. Based on this classical notion, we introduce the $m$-binomial equivalence of two words refining the abelian equivalence. Two words $x$ and $y$ are $m$-binomially equivalent, if, for all words $v$ of length at most $m$, the binomial coefficients of $x$ and $v$ and respectively, $y$ and $v$ are equal. The $m$-binomial complexity of an infinite word $x$ maps an integer $n$ to the number of $m$-binomial equivalence classes of factors of length $n$ occurring in $x$. We study the first properties of $m$-binomial equivalence. We compute the $m$-binomial complexity of two classes of words: Sturmian words and (pure) morphic words that are fixed points of Parikh-constant morphisms like the Thue--Morse word, i.e., images by the morphism of all the letters have the same Parikh vector. We prove that the frequency of each symbol of an infinite recurrent word with bounded $2$-binomial complexity is rational. [less ▲]

We evaluated the sequence in 1769 (CyTBI, n ¼ 948; TBICy, n ¼ 821) recipients of related or unrelated hematopoietic cell transplantation who received TBI (1200 to 1500 cGY) for acute leukemia from 2003 to 2010. The 2 cohorts were comparable for median age, performance score, type of leukemia, first complete remission, Philadelphia chromosomeepositive acute lymphoblastic leukemia, HLAmatched siblings, stem cell source, antithymocyte globulin use, TBI dose, and type of graft-versus-host disease (GVHD) prophylaxis. The sequence of TBI did not significantly affect transplantation-related mortality (24% versus 23% at 3 years, P ¼.67; relative risk, 1.01; P ¼.91), leukemia relapse (27% versus 29% at 3 years, P ¼ .34; relative risk, .89, P ¼.18), leukemia-free survival (49% versus 48% at 3 years, P ¼.27; relative risk, .93; P ¼ .29), chronic GVHD (45% versus 47% at 1 year, P ¼.39; relative risk, .9; P ¼ .11), or overall survival (53% versus 52% at 3 years, P ¼.62; relative risk, .96; P ¼.57) for CyTBI and TBICy, respectively.

Objective: Based on the case study of Jeanne, the objective of this article is to study patterns of anorexic people’s specific being-in-the-world. We seek to identify the core vulnerability features of anorexic existence, beyond the dimension of feeding alone. The identification of a psychopathological structure will result in a better understanding of Jeanne’s clinical situation and will help to formulate psychotherapeutic and prophylactic recommendations. Method: A phenomenological and ethological approach allows us to see past the strictly medical symptoms (eating disorder). The evolutionary perspective highlights the adaptive dimension of this disorder (e.g., in extreme situations such as famine). Specifically, Demaret’s ethological hypothesis identifies altruism (feeding altruism and generalized altruism) as the core feature of anorexic conduct. Phenomenological reflection (phenomenological psychopathology and phenomenological philosophy) appears to complement the ethological approach. Phenomenology distinguishes two kinds of bodies: the Leib (emotional, subjective and experienced in the first person) and the Körper (devitalized, objective and experienced in the second person). Merleau-Ponty’s works highlight the difference between the touching body and the touched body. These proposals show the problematic of the other in body configuration. It is in precisely this connection that anorexic existence is specific. Sartre’s phenomenology and the lived-body-for-others is the final step of our reasoning to arrive at a configuration of intersubjectivity. Results: The analysis of Jeanne’s case, combined with ethological and phenomenological perspectives, demonstrates that the real psychopathological structure of anorexic subjectivity rests on specific interaction modes. The notions of altruism, lived-body-for-others, and intersubjectivity highlight an emotional existence including shame in the eyes of others, and especially an imbalance between self-preservation and care for others. Conclusions: All our thinking suggests that so-called “denial” is a psychological mechanism that should be reconsidered. Denial is not a mechanism of anorexic subjects alone, but is also a process encountered both in the patient’s family and in the therapeutic environment. Anorexic denial is based on anosognosia and the refusal to see one’s own thinness, while other people’s denial constitutes a widespread inability to perceive the altruism and intersubjective problematic on which the existence of an anorexic subject fundamentally depends.

Burkitt lymphoma (BL) is a rare but very aggressive non-Hodgkin’s lymphoma characterized by an isolated translocation t(8;14)(q24;q32). The sporadic form is the subentity most frequently encountered in our country. Diagnosis and initial work-up must be completed rapidly to start treatment as soon as possible. Positron emission tomography (PET) scan is useful for initial staging and to evaluate the chemosensitivity of the tumor during and after treatment. After debulking, it is recommended to add rituximab to chemotherapy. Currently intensive short-cycle chemotherapies (ISCC) and low intensity chemotherapies (LIC) are two valuable options. Radiotherapy is not indicated except in case of central nervous system involvement. Patients achieving complete remission must be followed carefully during the first year to detect recurrence of the disease. More than 80% of patients sustain their remission one year following initial treatment and are considered cured. For patients in partial remission or with chemosensitive relapse, autologous stem cell transplantation is recommended following re-induction with non-cross-resistant polychemotherapy. Monitoring complete blood counts and cognitive functions is important to detect late toxicity of the applied therapies. [less ▲]

Sensitivity to initial conditions is usually associated with chaotic dynamics and strange attractors. However, even systems with (quasi)periodic dynamics can exhibit it. In this context we report on the fractal properties of the isochrons of some continuous-time asymptotically periodic systems. We define a global measure of phase sensitivity that we call the phase sensitivity coefficient and show that it is an invariant of the system related to the capacity dimension of the isochrons. Similar results are also obtained with discrete-time systems. As an illustration of the framework, we compute the phase sensitivity coefficient for popular models of bursting neurons, suggesting that some elliptic bursting neurons are characterized by isochrons of high fractal dimensions and exhibit a very sensitive (unreliable) phase response.

Background: Burn patients are at risk of vitamin D (VD) deficiency and may benefit from its pleiotropic effects as soon as acute phase. Aim of this observational study was to assess effects of a cholecalciferol (VD3) bolus on VD status in adult burn patients (Group B, GB) after admission, compared to healthy subjects (Group H, GH). Methods: Both groups received an oral dose of 100,000 IU VD3. Blood samples were collected before (D0) and 7 days (D7) after bolus to measure 250H-D, 1,25(OH)2-D, parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23). Albumin (ALB) and VD binding protein (DBP) were measured and used to calculate free 25OH-D level. Data were expressed as median (min–max) or proportions. Results: A total of 49 subjects were included: 29 in GH and 20 in GB. At D0, prevalence of VD deficiency was higher in GB: 25OH-D was 21.5 (10.1–46.3) ng/ml in GH vs 11 (1.8–31.4) ng/ml in GB. DBP and ALB were lower in GB. At D7, DBP was stable in both groups while ALB decreased in GB. 25OH-D increased by 66.6 (13.5–260.3)% in GH. In GB, changes in 25OH-D extended from 36.7% to 333.3% with a median increase of 33.1%. Similar changes were observed in each group for free 25OH-D. High FGF23 levels were observed in GB. Conclusions: This study highlighted the differences in VD status and in response to a high dose VD3 in burn patients when compared to healthy patients. Pitfalls in VD status assessment are numerous during acute burn care: 25OH-D measurement needs cautious interpretation and interest of free 25OH-D is still questionable. They should not prevent burn patients to receive VD supplements during acute care. Higher doses than general recommendations should probably be considered. [less ▲]

We examined children’s ability to employ a metacognitive heuristic based on memorability expectations to reduce false recognitions, and explored whether these expectations depend on the context in which the items are presented. Specifically, 4-, 6-, and 9-year-old children were presented with high-, medium-, and low-memorability words, either mixed together (Experiment 1) or separated into two different lists (Experiment 2). Results revealed that only children with a higher level of executive functioning (9-year-olds) used the memorability-based heuristic when all types of items were presented within the same list. However, all children, regardless of age or executive level, implemented the metacognitive rule when high- and low-memorability words were presented in two separate lists. Moreover, the results of Experiment 2 showed that participants processed medium-memorability words more conservatively when they were presented in a low- than in a high-memorability list, suggesting that children’s memorability expectations are sensitive to list-context effects.

This article emphasizes the impacts of international migration on ageing processes and norms within transnational families, and, specifically, analyses the roles of the zero generation, defined as the parents of first-generation migrants (Nedelcu 2009), both as non-migrant counterparts to their children abroad and as ageing migrants themselves. Transnational caregiving research has demonstrated that for many migrants and their families care arrangements must be negotiated across national borders, yet the agency of transnational older adults has been largely neglected. Based on qualitative fieldwork conducted from 2011 to 2013 in Liège, Belgium and Oujda, Morocco, the present article examines the circulation of care between Moroccan adult migrants and their ageing ascendants. This article exposes the duality of migrants’ ascendants as care givers and recipients, asserting firstly, that receiving care is not synonymous with passivity, and that, secondly, migrants’ ascendants are also the initiators of transnational practices. In both roles, this article underlines mobility as a strategy used by migrants’ parents to maintain family solidarity across national borders, but that this care mobility is limited by macro-level migration policies, here exemplified by the Belgian migration regime.

A majority of multiple myeloma patients present with osteolytic bone lesions that can cause bone pain, fractures or hypercalcaemia. Correct identification of these lesions is important in the initial assessment of the disease. Although the radiological skeletal survey is the gold standard to detect bone osteolytic lesions, it may miss small bone lesions or lesions located in the spine or pelvis due to the superimposed images of soft tissues. These limitations propelled newer imaging techniques such as positron emission tomography combined with computed tomography (PET/CT) and magnetic resonance imaging (MRI) in the diagnosis of multiple myeloma. In addition, 18F-fluorodeoxyglucose PET/CT and MRI have prognostic value and can be used to monitor disease. This review discusses the additional value of PET/CT and MRI in the management of MM.

Human biomonitoring (HBM) is an effective tool for assessing actual exposure to chemicals that takes into account all routes of intake. Although hair analysis is considered to be an optimal biomarker for assessing mercury exposure, the lack of harmonization as regards sampling and analytical procedures has often limited the comparison of data at national and international level. The European-funded projects COPHES and DEMOCOPHES developed and tested a harmonized European approach to Human Biomonitoring in response to the European Environment and Health Action Plan. Herein we describe the quality assurance program (QAP) for assessing mercury levels in hair samples from more than 1800 mother–child pairs recruited in 17 European countries. To ensure the comparability of the results, standard operating procedures (SOPs) for sampling and for mercury analysis were drafted and distributed to participating laboratories. Training sessions were organized for field workers and four external quality-assessment exercises (ICI/EQUAS), followed by the corresponding web conferences, were organized between March 2011 and February 2012. ICI/EQUAS used native hair samples at two mercury concentration ranges (0.20–0.71 and 0.80–1.63) per exercise. The results revealed relative standard deviations of 7.87–13.55% and 4.04–11.31% for the low and high mercury concentration ranges, respectively. A total of 16 out of 18 participating laboratories the QAP requirements and were allowed to analyze samples from the DEMOCOPHES pilot study. Web conferences after each ICI/EQUAS revealed this to be a new and effective tool for improving analytical performance and increasing capacity building. The procedure developed and tested in COPHES/DEMOCOPHES would be optimal for application on a global scale as regards implementation of the Minamata Convention on Mercury. [less ▲]

Lignocellulosic biomass residues have attracted attention for the sustainable production of molecules for material and energetic use through biochemical conversion. Their recalcitrant structure prevents a broader use and asks for the development of sustainable techniques that can efficiently separate, recover and valorize the constituting components. In a cascading concept, residual streams of such processes can be further exploited in an attempt to valorize the largest possible fraction of the initial material. Three lignocellulosic substrates, namely dried sugar beet pulp, wheat bran and miscanthus straw, were upstream fractionated by steam explosion to extract the hemicellulose fraction. This study evaluated the valorization of the residual solid fraction through mixed acidogenic fermentation for the production of volatile fatty acids (VFA) as platform chemicals. Batch experiments have been conducted for the reference material (non-treated) and the solid fraction remaining after steam explosion, with and without the addition of an external mixed inoculum. Steam explosion residues contained less hemicellulose than the initial materials. The difference in the fermentation profile between steam explosion residues and non-treated substrates is dependent on the substrate. Maximum total VFA (tVFA) concentration was 18.8 gCOD/kgmixed_liquor, and maximum yield of chemical oxygen demand (COD) conversion into tVFAwas 33 % for the case of non-treated inoculated beet pulp.

The paper first distinguishes ritual action for sovereigns, which integrates the honoured rulers at a practical level within the religious life of a community, from other, more discrete configurations of the relation between royal and divine power. Among these trends, focus is on the rhetorical and spectacular dimension of wonder. The strategies of wonder-making are first studied in theory through paradoxography, then the categories of grandeur, exoticism and technical excellence are identified in action in Alexandrian religious life and festivals. Master of an empire with universal claims and collector of everything that is beautiful, rare and precious in the world, the king distances himself from his subjects in order to make his superior status explicit. Distance is, however, only the premise for the king to manifest himself to the great public through epiphanies that can be compared with those of divine power. The paper also discusses the way the conformism of court elites not only satisfied their own need to claim for distinguished social status, but also helped royal message spread and caused loyalty to it.

This conceptual paper aims to respond to the poorly addressed question of the emergence of hybrid organizations – i.e. organizations that embrace several institutional logics. It does so by developing a model and a set of propositions focusing on the heterogeneity of the entrepreneurial team as a possible driver for hybridity throughout the entrepreneurial process and up to the emergence of a hybrid organization. As contributions to the literatures on (collective) entrepreneurship, imprinting and hybrid organizations, we advance several avenues and conditions under which the heterogeneity of the entrepreneurial team may imprint the entrepreneurial process and lead to the creation of hybrid organizations. Our propositions connect the individual, team and organizational levels and thus advance our understanding of how institutional logics can be combined across different levels of analysis and throughout the stages of an entrepreneurial process.

First in the USA and then in many other countries, scholarship on environmental inequality has sought to shed light on the unequal environmental conditions borne by poor people and ethnic minorities, and to challenge public policies and their unjust impacts on those target groups. Housing quality, especially the indoor characteristics of homes, offers an innovative perspective in this field of research. In previous research on environmental inequality in the Walloon context, housing quality has been proven to be a major determinant of quality of life and environmental well-being. This paper analyses housing quality through a twofold approach: through indoor characteristics on the one hand, and outdoor subjective and objective externalities on the other. It reveals the disparities between the most deprived and the wealthiest segments of the population. The evidence for this study is based on a housing quality survey carried out in 2012 and 2013 on 6,018 households in Wallonia (Belgium). The key findings are that poor people are found to live in housing of lower quality, in densely populated neighbourhoods and those with mixed use, with compensating amenities provided at the local level. Moreover, consistent with environmental inequality scholarship, deprived households are found to bear the burden of environmental degradation outside the home. People live in areas with poorer air quality, but are found to benefit from greater access to green spaces. The results of the survey reveal an interesting point concerning the environmental inequality literature; the interior features of housing are found to differ more widely between deprived and wealthier people than the surrounding environment does.

Dans l’une de ses conversations avec Joachim Gasquet sur le sens de sa peinture (et de la peinture en général), Cézanne aborde de front la conception qu’il se fait de la couleur, dans son rapport à la profondeur picturale et de son articulation à la surface : « La nature n'est pas en surface ; elle est en profondeur. Les couleurs sont l'expression, à cette surface, de cette profondeur. Elles montent des racines du monde ». Cet « organisme de couleurs » que constitue le monde est transcrit dans la peinture de Cézanne par une dynamique symbiotique de la couleur et du dessin, de la ligne et du pan. La couleur restitue, par sa masse, son surgissement, son homogénéité, presque sa viscosité, la véritable chaire perceptive du monde ; une vision qui tient à distance la perspective géométrique, photographique, cinématographique fondée sur la transparence et qui repose, comme le signale Merleau-Ponty, sur la « réversibilité des dimensions » (surface-profondeur) et l’entrelacement des choses. C’est cette épaisseur du visible rendu par la couleur que l’économie de l’image numérique nous permet de redécouvrir, moins dans le registre de la « tactilité » de l’image et la picturalité du pixel, que par l’intégration, entre le support et l’image (parfois indiscernables dans le régime optique), d’un « corps » algorithmique qui règle l’actualisation du visible. Certains défauts techniques du dispositif numérique, aujourd’hui élevés au rang de pratique artistique, permettent de révéler cette matrice qui utilise alors la couleur et la coulure comme mode de visibilité. C’est le cas du Datamoshing, technique de composition numérique qui revisite tout en la radicalisant la pratique de l’incrustation vidéo. Basée sur la perturbation volontaire d’éléments de la matrice, cette technique transforme les couleurs en une forme malléable et fluide révélant ainsi leur double nature spatiale : elles sont à la fois dans l’espace de l’image et l’espace de l’image lui-même. Ces expériences de défigurations d’images s’inscrivent dans le registre des « aberrations chromatiques » dont nous proposons ici une rapide généalogie avant d’interroger la couleur digitale dans ses spécificités.

This paper focuses on the computation of asymptotic standard errors (ASE) of ability estimators with dichotomous item response models. A general framework is considered and ability estimators are defined from a very restricted set of assumptions and formulas. This approach encompasses most standard methods such as maximum likelihood, weighted likelihood, maximum a posteriori and robust estimators. A general formula for the ASE is derived from the theory of M-estimation. Well-known results are found back as particular cases for the maximum and robust estimators, while new ASE proposals for the weighted likelihood and maximum a posteriori estimators are presented. These new formulas are compared to traditional ones by means of a simulation study under Rasch modeling. [less ▲]

1. Plant functional traits, in particular specific leaf area (SLA), wood density and seed mass, are often good predictors of individual tree growth rates within communities. Individuals and species with high SLA, low wood density and small seeds tend to have faster growth rates. 2. If community-level relationships between traits and growth have general predictive value, then similar relationships should also be observed in analyses that integrate across taxa, biogeographic regions and environments. Such global consistency would imply that traits could serve as valuable proxies for the complex suite of factors that determine growth rate, and, therefore, could underpin a new generation of robust dynamic vegetation models. Alternatively, growth rates may depend more strongly on the local environment or growth–trait relationships may vary along environmental gradients. 3. We tested these alternative hypotheses using data on 27 352 juvenile trees, representing 278 species from 27 sites on all forested continents, and extensive functional trait data, 38% of which were obtained at the same sites at which growth was assessed. Data on potential evapotranspiration (PET), which summarizes the joint ecological effects of temperature and precipitation, were obtained from a global data base. 4. We estimated size-standardized relative height growth rates (SGR) for all species, then related them to functional traits and PET using mixed-effect models for the fastest growing species and for all species together. 5. Both the mean and 95th percentile SGR were more strongly associated with functional traits than with PET. PET was unrelated to SGR at the global scale. SGR increased with increasing SLA and decreased with increasing wood density and seed mass, but these traits explained only 3.1% of the variation in SGR. SGR–trait relationships were consistently weak across families and biogeographic zones, and over a range of tree statures. Thus, the most widely studied functional traits in plant ecology were poor predictors of tree growth over large scales. 6. Synthesis. We conclude that these functional traits alone may be unsuitable for predicting growth of trees over broad scales. Determining the functional traits that predict vital rates under specific environmental conditions may generate more insight than a monolithic global relationship can offer. [less ▲]

BACKGROUND: Single cell biology has attracted a lot of attention these past few years and has led to numerous fundamental results pointing out the heterogeneity of clonal cell populations. In this context, microbial phenotypic heterogeneity under bioprocessing conditions needs to be further investigated. In this study, yeast based processes have been investigated by using on-line flow cytometry in combination with a fluorescent transcriptional reporter (GFP) and viability fluorescence tags (propidium iodide, PI). Methods aiming at expressing the dispersion of these fluorescence tags among the yeast populations have been investigated for different bioreactor operating conditions. RESULTS: Yeast viability was determined on the basis of PI uptake. Segregation between PI negative and positive subpopulations could be efficiently quantified on the basis of the mean-to-median ratio or the amplitude of the interquartile range. On the other hand, the same quantification could not be made for the segregation occurring at the level of GFP synthesis. Indeed, when cells were exposed to sub-lethal or mild stresses (such as in scale-down reactors) two GFP subpopulations could be visualized by real-time FC, but quantification by one of the above-mentioned methods was not possible. CONCLUSIONS: Yeast population heterogeneity was observed in representative bioreactor operating conditions. Difficulties for the determination of segregation at the level of GFP synthesis point out the fact that one needs to understand the segregation mechanisms for the applied fluorescent reporters, to judge whether simple mathematical tools may be applied or if more sophisticated computational tools are needed for the quantification of the microbial population segregation.

Technology advances can revolutionize Precision Forestry by providing accurate and fine forest information at tree level. This paper addresses the question of how and particularly when Unmanned Aerial System (UAS) should be used in order to efficiently discriminate deciduous tree species. A time series of high resolution UAS imagery was collected to cover the growing season from leaf flush to leaf fall. Full benefit was taken of the temporal resolution of UAS acquisition, one of the most promising features of small drones. The disparity in forest tree phenology is at the maximum during early spring and late autumn. But the phenology state that optimized the classification result is the one that minimizes the spectral variation within tree species groups and, at the same time, maximizes the phenologic differences between species. Sunlit tree crowns (5 deciduous species groups) were classified using a Random Forest approach for monotemporal, two-date and three-date combinations. The end of leaf flushing was the most efficient single-date time window. Multitemporal datasets definitely improve the overall classification accuracy. But single-date high resolution orthophotomosaics, acquired on optimal time-windows, result in a very good classification accuracy (overall out of bag error of 16%). [less ▲]

Immunosenescence as complex modifications of immunity with age could be related to the so-called frailty syndrome of elderly leading to an inadequate response to minimal aggression. Functional decline, the loss of ability to perform activities of daily living, is related to the decrease in physiological reserves and frailty and is a frequent outcome of hospitalization in older patients. Links between immunosenescence and frailty were explored and 20 immunological parameters were affected in seniors with functional decline. IGF-1, thymopoeisis and telomere length were part of these markers. A strong relationship between insulin-like growth factor-1 (IGF-1) and thymic ouput was evidenced. IGF-1, mediator of GH, was subsequently shown to induce IL-7 secretion in cultured primary human thymic epithelial cells (TECs). We are also exploring the ‘stress hypothesis’ according which an acute stress is the discriminator revealing a frailty susceptility. GH can counteract the deleterious immunosuppressive effect of stress-induced steroids. Under non-stressing conditions, the immunosenescent system preserves physiological responses, while in stressing conditions, the combination of immunosenescence and a defect in somatotrope axis might lead to functional decline.

The CO2 post-combustion capture with amine solvents is modeled as a complex system interconnecting process energy consumption and solvent degradation and emission. Based on own experimental data, monoethanolamine degradation is included into a CO2 capture process model. The influence of operating conditions on solvent loss is validated with pilot plant data from literature. Predicted solvent consumption rates are in better agreement with plant data than any previous work, and pathways are discussed to further refine the model. Oxidative degradation in the absorber is the largest cause of solvent loss while thermal degradation does not appear as a major concern. Using a single model, the process exergy requirement decreases by 10.8% and the solvent loss by 11.1% compared to our base case. As a result, this model provides a practical tool to simultaneously minimize the process energy requirement and the solvent consumption in post-combustion CO2 capture plants with amine solvents.

Since the early 2000s, Ethiopia has witnessed the rapid growth of a local digital film industry whose economic model is similar to the one adopted by other industries of this kind emerged in African countries such as Nigeria, Ghana and Tanzania. Films are shot in digital format, are independently funded and commercially-driven, use Amharic as main language and target local and diasporic audiences. Unlike other productions of this kind around the continent, however, Ethiopian video films are firstly released in the large cinema theatres that characterize Addis Ababa’s urban landscape, and later circulate via VCDs, in Ethiopia, and in internet, throughout the diaspora. As this essay will argue, this aspect gives to the Ethiopian video film phenomenon a number of important specificities which make the study of Ethiopian film production and distribution particularly interesting. Furthermore, within a context defined by a relatively tight governmental control on media production and circulation, the emergence of this phenomenon is introducing important transformations, and modifying the way locally-produced media are perceived and consumed within the Ethiopian public sphere. While being commercially oriented, in fact, videos do produce a social and moral commentary which portrays, and in some cases criticizes, the way the society has transformed over the past few years. This article presents the preliminary results of an ongoing research on the raising Ethiopian digital film industry, conducted as part of a post-doctoral research project which analyses and compares the economy of digital filmmaking in a few sub-Saharan African countries. The data presented here have been collected through interviews, archival research and participant observation on film sets and distribution venues during a three months research stay in Addis Ababa between the end of 2013 and the beginning of 2014. The paper is divided into four main sections: the first two trace the history of filmmaking in Ethiopia and the emergence of the video phenomenon within this context, the third focuses on the analysis of the video industry’s economy and describes its main specificities, and the fourth presents an overview of the main narrative and aesthetic trends emerged within the context of the Ethiopian film production until today.

Poly(2-dimethylamino)ethyl methacrylate (PDMAEMA) is an attractive polycation frequently proposed as a non-viral vector for gene therapy. As expected for other cationic carriers, intravenous administration of PDMAEMA can result in its ionic complexation with various negatively charged domains found within the blood. To gain more insight into this polycation hemoreactivity, we followed the binding kinetics of a free form (FF) of fluorescein labelled PDMAEMA (below 15 kDa) in normal human blood using flow cytometry. This in vitro study highlighted that platelets display higher affinity for this polycation compared to red blood cells (RBCs), with an adsorption isotherm characteristics of a specific saturable binding site. PDMAEMA (1-20μg/mL) exerted a concentration dependent proaggregant effect with a biphasic aggregation of washed platelets. Activation of platelets was also noticed in whole blood with the expression of P-selectin and fibrinogen on platelet surface. Although additional studies would be needed in order to elucidate the mechanism of PDMAEMA mediated activation of platelets, our manuscript provides important information on the hemoreactivity of FF PDMAEMA.

For more than a decade, the taxonomy of Phormidiaceae has been problematic, since morphologically similar organisms represent phylogenetically distinct entities. Based on 16S rRNA analyses, the polyphyletic genus Phormidium and other gas-vacuolated oscillatorioids appear scattered throughout the cyanobacterial tree of life. Recently, several studies have focused on understanding the oscillatorioid taxa at the generic level. At the specific level, there are few studies characterizing cyanobacterial strains using combined datasets (morphology, ultrastructure, and molecular multi-locus analyses). Using a multi-facet approach, we propose a new, well-defined genus, Cephalothrix gen. nov., by analyzing seven filamentous strains morphologically 'intermediate' between gas-vacuolated taxa and Phormidium. Furthermore, we characterize two new species: Cephalothrix komarekiana (CCIBt 3277, CCIBt 3279, CCIBt 3523, CCALA 155, SAG 75.79, and UTEX 1580) and Cephalothrix lacustris (CCIBt 3261). The generic name and specific epithets were proposed under the provisions of the International Code of Nomenclature for algae, fungi, and plants. [less ▲]

Pneumocystis fungi represent a highly diversified biological group with numerous species, which display a strong host-specificity suggesting a long co-speciation process. In the present study, the presence and genetic diversity of Pneumocystis organisms was investigated in 203 lung samples from woodmice (Apodemus sylvaticus) collected on western continental Europe and Mediterranean islands. The presence of Pneumocystis DNA was assessed by nested PCR at both large and small mitochondrial subunit (mtLSU and mtSSU) rRNA loci. Direct sequencing of nested PCR products demonstrated a very high variability among woodmouse-derived Pneumocystis organisms with a total number of 30 distinct combined mtLSU and mtSSU sequence types. However, the genetic divergence among these sequence types was very low (up to 3.87%) and the presence of several Pneumocystis species within Apodemus sylvaticus was considered unlikely. The analysis of the genetic structure of woodmouse-derived Pneumocystis revealed two distinct groups. The first one comprised Pneumocystis from woodmice collected in continental Spain, France and Balearic islands. The second one included Pneumocystis from woodmice collected in continental Italy, Corsica and Sicily. These two genetic groups were in accordance with the two lineages currently described within the host species Apodemus sylvaticus. Pneumocystis organisms are emerging as powerful tools for phylogeographic studies in mammals [less ▲]

The high species richness of tropical forests has long been recognized, yet there remains substantial uncertainty regarding the actual number of tropical tree species. Using a pantropical tree inventory database from closed canopy forests, consisting of 657,630 trees belonging to 11,371 species, we use a fitted value of Fisher’s alpha and an approximate pantropical stem total to estimate the minimum number of tropical forest tree species to fall between ∼40,000 and ∼53,000, i.e., at the high end of previous estimates. Contrary to common assumption, the Indo-Pacific region was found to be as species-rich as the Neotropics, with both regions having a minimum of ∼19,000–25,000 tree species. Continental Africa is relatively depauperate with a minimum of ∼4,500–6,000 tree species. Very few species are shared among the African, American, and the Indo-Pacific regions. We provide a methodological framework for estimating species richness in trees that may help refine species richness estimates of tree-dependent taxa. [less ▲]

Cet article prend appui sur une recherche doctorale. A partir de l’analyse de récits d’expériences marquantes, à forte charge émotionnelle, rapportées par des enseignants débutants, des schémas d’intelligibilité de ces situations vécues ont été construits. Ceux-ci rendent compte des transformations identitaires et émotionnelles des enseignants débutants au travers des dynamiques transactionnelles de reconnaissance. Ces résultats ouvrent des perspectives pour la formation initiale des enseignants et l’accompagnement des enseignants débutants. Les schémas d’intelligibilité pourront être utilisés dans une démarche de réflexivité pour faciliter le décodage de situations professionnelles à forte charge émotionnelle vécues par l’enseignant et l’aider à donner sens à ses expériences [less ▲]

L’image, sous ses divers aspects, a joué un rôle essentiel dans la vie des anciens Grecs, en particulier dans le domaine religieux, puisque elle était l’une des modalités de perception du divin. En Grèce, la figuration anthropomorphe des dieux est largement majoritaire. Toutefois, en se tournant vers un support particulier, le vase peint, et un type de représentation particulier, la statue divine, on montrera ici que l’anthropomorphisme a pu amener une certaine ambiguïté. Dans la céramique, les représentations de statues fonctionnent sur plusieurs modes, selon la chronologie. C’est ce que l’on propose d’analyser, en examinant un groupe de vases décorés d’un thème semblable et sur lesquels une divinité est représentée, mais soit sous la forme d’une figure « vivante », soit d’une statue plus ou moins bien caractérisée. Cette étude permettra d’aborder les concepts de « fixité » et de « mouvement » de/dans l’image, mais aussi d’explorer quelques pistes de réflexions sur l’image divine et, plus largement, sur les modes de représentation du divin en Grèce ancienne.
