Objective: People with accurate representations of their own cognitive functioning (i.e., cognitive self-awareness) tend to use appropriate strategies to regulate their behavior. Due to the lack of appropriate instruments, few studies have examined the development of this ability among children. Method: This study tested the measurement properties of the self-rating and other-rating forms of the Questionnaire of Executive Self-Awareness (QESA), designed to tap children’s knowledge of their executive functioning. Participants were 317 children aged 7 to 14 years old. Results: Confirmatory factor analyses carried out on the QESA confirmed the eight-factor structure of both versions. There were significant correlations between the QESA and the parent versions of the BRIEF, DEX-C, and CHEXI. Both forms of the QESA were able to distinguish between children who had sustained a traumatic brain injury (TBI) and control participants. A self-other discrepancy score was computed to assess children’s executive self-awareness. A statistical difference was observed between the TBI and control groups on this score, suggesting that TBI may trigger self-awareness impairments in children. Conclusion: The good psychometric properties of the two forms of the QESA were established. Furthermore, results of the analyses carried on the different discrepancy scores seem to indicate that the QESA could help clinicians to detect patients with self-awareness deficits. [less ▲]

BACKGROUND: Minimally invasive valve surgery is related to certain better postoperative outcomes. We aimed to assess the role of minimally invasive mitral valve surgery in high-risk patients. METHODS: A systematic literature review identified eight studies of which seven fulfilled criteria for meta-analysis. Outcomes for a total of 1,254 patients (731 were conventional standard sternotomy and 523 were minimally invasive mitral valve surgery) were submitted to meta-analysis using random effects modeling. Heterogeneity and subgroup analysis with quality scoring were assessed. The primary end point was early mortality. Secondary end points were intraoperative and postoperative outcomes and long-term follow-up. RESULTS: Minimally invasive mitral valve surgery conferred comparable early mortality to standard sternotomy (p = 0.19); it was also associated with a lower number of units of blood transfused (weighted mean difference, -1.93; 95% confidence interval [CI], -3.04 to -0.82; p = 0.0006) and atrial fibrillation rate (odds ratio, 0.49; 95% CI, 0.32 to 0.74; p = 0.0007); however, cardiopulmonary bypass time was longer (weighted mean difference, 20.88; 95% CI, -1.90 to 43.65; p = 0.07). There was no difference in terms of valve repair rate (odds ratio, 1.51; 95% CI, 0.89 to 2.54; p = 0.12), and the incidence of stroke was significantly lower in the high-quality analysis with no heterogeneity (odds ratio, 0.35; 95% CI, 0.15 to 0.82; p = 0.02; chi2, 1.67; I2, 0%; p = 0.43). CONCLUSIONS: Minimally invasive mitral valve surgery is a safe and comparable alternative to standard sternotomy in patients at high risk, with similar early mortality and repair rate and better postoperative outcomes, although a longer cardiopulmonary bypass time is required.

The role of aerial dispersal in shaping patterns of biodiversity remains poorly understood, mainly due to a lack of coordinated efforts in gathering data at appropriate temporal and spatial scales. It has been long known that the rate of dispersal to an ecosystem can significantly influence ecosystem dynamics, and that aerial transport has been identified as an important source of biological input to remote locations. With the considerable effort devoted in recent decades to understanding atmospheric circulation in the south-polar region, a unique opportunity has emerged to investigate the atmospheric ecology of Antarctica, from regional to continental scales. This concept note identifies key questions in Antarctic microbial biogeography and the need for standardized sampling and analysis protocols to address such questions. A consortium of polar aerobiologists is established to bring together researchers with a common interest in the airborne dispersion of microbes and other propagules in the Antarctic, with opportunities for comparative studies in the Arctic.

The present paper looks into the problem of optimising the loading of boxes into containers. The goal is to minimise the unused volume. This type of problem belongs to the family of Multiple Bin Size Bin Packing Problems. The approach includes an extensive set of constraints encountered in real-world applications in the three-dimensional case: the stability, the fragility of the items, the weight distribution and the possibility to rotate the boxes. It also includes the specific situation in which containers are truncated parallelepipeds. This is typical in the field of air transportation. While most papers on cutting and packing problems describe ad-hoc procedures, this paper proposes a mixed integer linear program. The validity of this model is tested on small instances. [less ▲]

Il volume ricostruisce la genesi e lo sviluppo dell’industria video nigeriana detta Nollywood, un sistema che produce 1000-1500 film ogni anno e li distribuisce direttamente in formato home-video. I video di Nollywood circolano in quasi tutta l’Africa sub-sahariana, nei Caraibi, in Nord America, in Canada e nella maggior parte dei paesi europei. Hanno dato vita a nuove forme di pan-africanismo, grazie alla combinazione tra il modo con cui sono prodotti e distribuiti e i valori estetici, culturali e sociali che essi veicolano. È un tipo di pan-africanismo ben diverso da quello promosso dai grandi portavoce della lotta anticoloniale, ma non per questo si dimostra meno efficace e influente. Il grande successo internazionale di Nollywood ha riaperto il dibattito su cosa significhi «essere africani oggi» e sulle trasformazioni sociali e culturali che hanno attraversato l’Africa negli ultimi anni.

In this work, physico-chemical properties and photocatalytic activity of three types of dried or dried and calcined TiO2 materials, synthesized by the cogelation method, were studied: (i) a pure TiO2 xerogel ; (ii) TiO2 xerogels doped with Ag ; (iii) TiO2 xerogels co-doped with Ag and P. The presence of silver nanoparticles was observed by transmission electron microscopy (TEM) and the oxidation state of silver after calcination was examined by temperature-programmed reduction (TPR) measurements. The physico-chemical properties of xerogels were characterized by X-ray diffraction (XRD), diffuse reflectance UV-Vis spectroscopy (DR UV-Vis) and from nitrogen adsorption-desorption isotherms. The photocatalytic activity of the samples was quantified for the p-nitrophenol degradation under visible light. [less ▲]

This article proposes an open-source testbed to simulate interaction models governing the exchange of flexibility services located within a distribution network. The testbed is an agent-based system in which the distribution system operator, the transmission system operator, producers and retailers make their decisions based on mixed-integer linear programs. This testbed helps to highlight the characteristics of an interaction model, the benefits for the agents and eases the detection of unwanted or abusive behaviors which decreases the welfare. The testbed is implemented in Python and the optimization problems are encoded in the modeling language ZIMPL. A web interface is coupled with an instance generator using macroscopic parameters of the system such as the total power production. This testbed is, therefore, well suited to test the implemented interaction models on various scenarios and to extend the implementation to other models. Five interaction models developed with industrial partners are simulated over a year on a 75-bus test system. Simulations show that interaction models relying on active network management, as they have been developed, lead to substantial welfare even though they suffer from a lack of coordination between the DSO and the TSO. A conservative interaction model restricting grid users to an access range that is computed ahead of time to prevent any congestion, avoids shedding distributed generation but considerably restrains the amount of distributed production.

The mere exposure effect is usually considered a robust phenomenon whereby people’s attitudes can easily be influenced. However, recent studies suggest that some conditions must be met for this effect to emerge. In this experiment, the influence of the features of a specific material on the mere exposure effect was examined in an ecological context. Children were told that they would play a game during which they would have to buy several items in different shops. In these shops, half of the participants were incidentally exposed to two target stimuli. During a subsequent judgment phase, the target stimuli were presented to each child, either with perceptually similar items or with perceptually dissimilar items. Prior encounter with an item only influenced children’s preference choices when the test items were dissimilar. These findings are discussed in terms of the processing styles that are necessary for the mere exposure effect to appear. [less ▲]

Selective timber production is implemented over a large proportion of the world’s tropical forests. Within these forest ecosystems, the frugivore community contributes important ecological services through animal-mediated seed dispersal. However, there is no clear understanding of the impacts of logging on wildlife or of the extent to which seed dispersal is preserved in logged forests. Given its tendency for nesting in light gaps, the western lowland gorilla is likely to provide directed-dispersal services to a wide range of tree species. Production forests preserved from poaching have been reported to harbor high densities of gorillas, but the monitoring of gorilla populations subjected to logging is poorly documented. This study investigated gorilla density and nesting behavior after timber exploitation in a logging concession in southeast Gabon. Nest count censuses were performed on line transects, before and after the second felling cycle. Gorilla density dropped from 1.5 (116.7 nests km 2, 95% CI = 83.4–163.5) to 1.0 (64.9 nests km 2, % CI = 32.6–129.5) weaned gorilla km 2 4–6 months after logging, then rose to 2.6 (176.3 nests km 2, 95% CI = 113.5–274.1) gorillas km 2 9–11 months after logging. A consistent preference for nesting in open canopy terra firma forest was observed during all censuses. This study demonstrates the short-term resilience of the western lowland gorilla to selective timber harvesting, and argues that they offer a continued contribution to directed-dispersal services within months after logging. Although a long-term monitoring of gorillas in a logged forest should be undertaken, the role of this species in logged forest recovery is thought to be important. The preservation of gorilla should receive particular consideration by forest managers. [less ▲]

Two methods were assessed for the generation of common N heterocyclic carbenes (NHCs) from stable imidazol(in)¬ium precursors using convenient and straightforward continuous-flow setups with either a heterogeneous inorganic base (Cs2CO3 or K3PO4) or a homoge¬neous organic base (KN(SiMe3)2). In-line quenching with carbon disulfide revealed that the homogeneous strategy was most efficient for the preparation of a small library of NHCs. The generation of free nucleophilic carbenes was next telescoped with two benchmark NHC-catalyzed reactions, namely, the transesterification of vinyl acetate with benzyl alcohol and the amidation of N-Boc-glycine methyl ester with ethanolamine. Both organocatalytic transfor¬ma¬tions proceeded with total conversion and excellent yields were achieved after extraction, showcasing the first examples of continuous-flow organocatalysis with NHCs.

INTRODUCTION: With 18F-FDG PET/CT, tumor uptake intensity and heterogeneity have been associated with outcome in several cancers. This study aimed at investigating whether 18F-FDG uptake intensity, volume or heterogeneity could predict the outcome in patients with non-small cell lung cancers (NSCLC) treated by stereotactic body radiation therapy (SBRT). METHODS: Sixty-three patients with NSCLC treated by SBRT underwent a 18F-FDG PET/CT before treatment. Maximum and mean standard uptake value (SUVmax and SUVmean), metabolic tumoral volume (MTV), total lesion glycolysis (TLG), as well as 13 global, local and regional textural features were analysed. The predictive value of these parameters, along with clinical features, was assessed using univariate and multivariate analysis for overall survival (OS), disease-specific survival (DSS) and disease-free survival (DFS). Cutoff values were obtained using logistic regression analysis, and survivals were compared using Kaplan-Meier analysis. RESULTS: The median follow-up period was 27.1 months for the entire cohort and 32.1 months for the surviving patients. At the end of the study, 25 patients had local and/or distant recurrence including 12 who died because of the cancer progression. None of the clinical variables was predictive of the outcome, except age, which was associated with DFS (HR 1.1, P = 0.002). None of the 18F-FDG PET/CT or clinical parameters, except gender, were associated with OS. The univariate analysis showed that only dissimilarity (D) was associated with DSS (HR = 0.822, P = 0.037), and that several metabolic measurements were associated with DFS. In multivariate analysis, only dissimilarity was significantly associated with DSS (HR = 0.822, P = 0.037) and with DFS (HR = 0.834, P < 0.01). CONCLUSION: The textural feature dissimilarity measured on the baseline 18F-FDG PET/CT appears to be a strong independent predictor of the outcome in patients with NSCLC treated by SBRT. This may help selecting patients who may benefit from closer monitoring and therapeutic optimization. [less ▲]
